| 1 | Laparoscopic low anterior resection for rectal carcinoma:Complications and management in 132 consecutive patients显示文摘AIM:To analyze the clinical manifestations and risk fac-tors of complications in laparoscopic low anterior resection(LAR)for rectal cancer patients.METHODS:A series of 132 consecutive patients who received laparoscopic LAR for rectal cancer in our center were included.The etiology,diagnosis,treatment and prevention of rectal cancer were studied among the patients with surgery-related complications using both univariate and multivariate regression analysis.RESULTS:No conversion to open surgery was observed and 5 cases converted to hand-assisted laparoscopic operation.The overall morbidity rate was 20.5%.Complications occurred during the operation in 7 patients(5.3%),within 30 postoperative days in 24 patients(18.2%),and within 3 mo in 2 patients(1.5%).The most significant complications were anastomotic leak-age(9.1%)and anastomotic hemorrhage(5.3%).Sizeand location of tumor,pathological staging and preoperative nutrition were significant factors associated with LAR complications,while gender,age and pathological type showed no relevance.Binary logistics regression showed that the size and location of tumor,and pathological staging were independent factors of laparoscopic LAR.All the complications were treated during their onset of clinical manifestations by interventional or conservative therapy.CONCLUSION:Anastomotic leakage is a major com-plication in laparoscopic LAR.The complications may be associated with tumor size and site,and pathological stage.Interventional therapies are of value in the management of laparoscopic LAR complications. | Qian-Lin Zhu,Bo Feng,Ai-Guo Lu,Ming-Liang Wang,Wei-Guo Hu,Jian-Wen Li,Zhi-Hai Mao,Min-Hua Zheng,Department of General Surgery,Shanghai Ruijin Hospital,Shanghai Jiao Tong University School of Medicine,Shanghai 200025,China Shanghai Minimally Invasive Surgery Center,Shanghai 200025,China | 2010 | World Journal of Gastroenterology2010，16，36： | 23 |
| 2 | Simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy for synchronous carcinoma of rectum and stomach显示文摘Laparoscopic resection of rectal cancer or gastric cancer has been advocated for the benefits of a reduced morbidity,a shorter treatment time,and similar outcomes.However,simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy for synchronous carcinoma of rectum and stomach are rarely documented in literature.Endoscopic examination revealed a synchronous carcinoma of rectum and stomach in a 55-year-old male patient with rectal bleeding and epigastric discomfort.He underwent a simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy with regional lymph nodes dissected.The operation time was 270 min and the estimated blood loss was 120 mL.The patient required parenteral analgesia for less than 24 h.Flatus was passed on postoperative day 3,and a solid diet was resumed on postoperative day 7.He was discharged on postoperative day 13.With the advances in laparoscopic technology and experience,simultaneous resection is an attractive alternative to a synchronous gastrointestinal cancer. | Qian-Lin Zhu,Min-Hua Zheng,Bo Feng,Ai-Guo Lu,Min-Liang Wang,Jian-Wen Li,Wei-Guo Hu,Lu Zang,Zhi-Hai Mao,Feng Dong,Jun-Jun Ma,Ya-Ping Zong,Department of General Surgery,Ruijin Hospital Affiliated to Shanghai Jiaotong University Shanghai Minimally Invasive Surgery Center,Shanghai 200025,China | 2008 | World Journal of Gastroenterology2008，14，21： | 11 |
| 3 | Reasonable choice of surgical procedures for patients with portal hypertension显示文摘OBJECTIVE: To assess individualized therapeutic protocol for patients with portal hypertension on thebasis of accumulated knowledge about the mechanism of portal hypertension.DATA SOURCES: Patients data on shunt and other surgical procedures from Ruijin Hospital, Shanghai,China and the published papers.RESULTS: The direction of blood flow of the collateral vessels in the gastro-splenic region is animportant factor in deciding surgical strategy because there is a close relationship between surgical riskand the classification of liver function. Clinically it is confirmed that each patient needs an individualizedsurgical procedure and that prophylactic operation is suitable for patients with splenomegaly, splenismassociated with serious esophageal varices and hemorrhagic tendency under endoscopy but acceptableliver function. The shunt diameter (SD) (SD=0.67×PVD) is determined in our patients according toindividualized hemodynamics. The rehemorrhagic rate after shunt being higher than that in others may berelated to lesioned gastric mucosa caused by portal hypertension or bleeding and temporary melena. Thisfinding is good for prevention of hepatic encephalopathy. The life quality and labor ability of patients willbe improved because of hepatopetal flow in the portal vein. With strict indications for reoperation,selective operation is performed as soon as possible when hemorrhage is controlled conservatively andliver function improved. Once the patient with cirrhosis associated with portal hypertension is scheduledfor liver transplantation, treatment of hemorrhage should aim to keep the patient in good condition and toavoid the protocol that may be disadvantageous to liver transplantation in the future.CONCLUSION: Surgical procedures for patients with portal hypertension should follow the principle ofindividualization. To obtain the best outcome, the choice of reasonable surgical procedure is expected. | Guang-Wen Zhou Zong-Yuan Tao Cheng-Hong Peng Hong-Wei Li the Surgical Department and Shanghai Digestive Surgical Institute, Ruijin Hospital, Shanghai Second Medical University, Shanghai 200025, China | 2003 | Hepatobiliary & Pancreatic Diseases International2003，2，3： | 8 |
| 4 | Diagnosis and treatment of solidpseudopapillary tumors of the pancreas显示文摘Solid-pseudopapillary tumors (SPTs) of the pancreas have been reported as rare lesions with' low malignant potential' occurring mainly in young women. This study was designed to define the clinicopathological characteristics and the effect of surgical intervention. METHODS:A retrospective clinical analysis was made of 21 patients with solid-pseudopapillary tumor of the pancreas admitted from June 1994 to December 2004. RESULTS:Abdominal pain as the major complaint was found in 13 patients, and palpable abdominal mass in 7. Imaging examination showed the abdominal mass clearly, but diagnosis was not defined. In 12 patients, tumors were located in the pancreatic head and in 9 patients, in the pancreatic tail. The average diameter of the tumor was 9.5 cm (range, 3-20 cm). One patient had liver metastasis. The diagnosis of the tumor was proved pathologically during operation in 14 patients, and other 3 patients who had been diagnosed as having insulinoma and other malignant tumors were confirmed by paraffin section and enzyme labeling after operation. Eighteen patients (85.7% ) were followed up with a median period of 24 months, 1-60 months without tumor recurrence. CONCLUSION:Huge pancreatic masses of the pancreas in young women are suggestive of solid-pseudopapillary tumors. Aggressive surgical therapy can result in good prognosis in these patients. | Xi Chen, Guang-Wen Zhou, Hui-Jiang Zhou, Cheng-Hong Peng and Hong-Wei Li Department of Surgery, Shanghai Institute of Digestive Surgery, Ruijin Hospital, Shanghai Second Medical University, Shanghai 200025, China | 2005 | Hepatobiliary & Pancreatic Diseases International2005，4，3： | 7 |
| 5 | Pancreatectomy combined with superior mesenteric-portal vein resection: report of 32 cases显示文摘BACKGROUND: Resection of the superior mesenteric- portal vein (SMPV) during pancreatoduodenectomy is dis- puted. Although the morbidity and mortality of patients af- ter this operation are acceptable, survival is limited. In this study, we evaluated the morbidity, mortality and survival of patients with ductal adenocarcinoma of the pancreas who had undergone pancreatectomy with en bloc portal vein re- section. METHODS: A total of 32 patients with ductal adenocarci- noma of the pancreas who had undergone pancreatectomy with SMPV resection between 1999 and 2003 were retro- spectively analyzed. In addition, they were categorized in- to two groups according to the invasion of the wall of the portal vein: group A (n =12), extended compression of the wall of the portal vein by surrounding carcinoma without true invasion and group B (n =20), true invasion including intramural and transmural invasion. RESULTS; The morbidity of the 32 patients was 31.25%. There was no operative death, and the overall 1-,3-year survival rates were 59% and 16%, respectively. The mean survival time of patients with microscopically positive mar- gin was only 5. 6 months as compared with 20 months in patients with microscopically negative margin. No diffe- rences in tumor size, margin positivity, nodal positivity, and 1-, 3-year survival rates were observed between the two groups. CONCLUSIONS; If selected carefully, pancreatectomy combined with SMPV resection can be performed safely, without increase in the morbidity and mortality. SMPV re- section should be performed only when a margin-negative resection is expected to be achieved. SMPV invasion is notassociated with histologic parameters suggesting a poor prognosis. | Guang-Wen Zhou, Wei-Ding Wu, Wei-Dong Xiao, Hong-Wei Li and Cheng-Hong Peng Shanghai, China Department of Surgery, Shanghai Institute of Diges- tive Surgery, Ruijin Hospital, Shanghai Second Medical University, Shang- hai 200025, China | 2005 | Hepatobiliary & Pancreatic Diseases International2005，4，1： | 6 |
| 6 | Surgical treatment for Nevin stage IV and V gallbladder carcinoma: report of 70 cases显示文摘BACKGROUND: The role of aggressive surgery for end-stage gallbladder carcinoma is controversial. This retrospective study was designed to evaluate the outcome of surgical treatment for Nevin stage Ⅳ and Ⅴ gallbladder carcinoma at a single institution. METHODS: A retrospective analysis was made on 70 patients with Nevin stage Ⅳ and Ⅴ gallbladder carcinoma undergoing surgical treatment from January 1993 to June 2004. RESULTS: There were 22 cases of stage Ⅳ and 48 of stage V. Cholecystectomy was performed in 37 cases with a resection rate of 53%,9 cases received radical resection, 13 extended radical resection, and 15 palliative resection. The curative resection rate was 31% and the morbidity rate was 36%. Postoperative 1-, 3-, 5-year survival rates of curative and palliative resection were 69%, 33%, 8% and 27%, 13%, 0, respectⅣely (P <0.01). The 1- and 3-year survival rates of patients undergoing exploratory laparotomy only were 3% and 0, respectively. CONCLUSIONS: Nevin stage Ⅳ and Ⅴ gallbladder carcinoma should be treated by aggressive surgery. Curative resection is promising in the improvement of long-term survⅣal rate. | Wei-Dong Xiao,Cheng-Hong Peng,Guang-Wen Zhou,Wei-Ding Wu, Bo-Yong Shen, Ji-Qi Yan,Wei-Ping Yang and Hong-Wei Li Department of Surgery, Ruijin Hospital, Shanghai Second Medical University, Shanghai 200025, China First author’s present address: Deparment of General Surgery, the First Affiliated Hospital, Nanchang University, Nanchang 330006, China | 2005 | Hepatobiliary & Pancreatic Diseases International2005，4，4： | 5 |
| 7 | Color Doppler ultrasonographic assessment of the risk of injury to major branch of the midddle hepatic vein during laparoscopic cholecystectomy显示文摘OBJEGTIVE: To investigate the causes of hemorrhage from the gallbladder bed during laparoscopiccholecystectomy.METHODS: 617 patients who had received laparoscopic cholecystectomy from September, 2000 to March,2001 at this hospital were reviewed retrospectively. Ninety-one of these patients were selected randomly forprospective observation. Color Doppler ultrasound was used to examine the cause of venous hemorrhage fromthe gallbladder bed during laparoscopic cholecystectomy and to examine the anatomic relationship betweenthe gallbladder bed and the branches of the middle hepatic vein in 91 patients preoperatively.RESULTS: A large branch of the middle hepatic vein extended closely behind the gallbladder bed in all91 patients. The mean distance between the closest point (C point) of this branch to the gallbladderbed was 5.0±4.6 mm. The branch of the middle hepatic vein was completely adherent to the gallbladderbed in 14 (15.38%) of the 91 patients. The distance between this branch and the gallbladder bed waswithin I mm in 10 (10.99%) of the 91 patients. The inside diameter at C point of this branch was3.2±1.1 mm. The C point was found on the left side of the longitudinal axis of the gallbladder in 31(34.66%) of the 91 patients, on the right side in 39 patients (42.86%), just on the axis in 21 patients(23.08%). The venous blood flow rate at the C point was 9.9±3.3 cm/s.CONCLUSIONS: A large branch of the middle hepatic vein passes behind the gallbladder. The insidediameter of this branch is relatively larger. The bleeding of this branch during operation can only bestopped by transfixion. The closest point of this vein to the gallbladder is mostly situated on the rightside of the longitudinal axis of the gallbladder. Patients with large branches of the middle hepatic veinclose to the gallbladder bed are at risk of hemorrhage during laparoscopic cholecystectomy and shouldbe identified preoperatively with ultrasound. | Bai-Yong Shen Hong-Wei Li Man Chen Min-Hua Zheng Lu Zang Shao-Min Jiang Jian-Wen Li Yu Jiang the Department of Surgery, Ruijin Hospital, Shanghai Second Medical University, Shanghai 200025, China Department of Ultrasonography, Ruijin Hospital, Shanghai Second Medical University, Shanghai 200025, China | 2003 | Hepatobiliary & Pancreatic Diseases International2003，2，1： | 4 |
| 8 | A Heat Budget Study on the Mechanism of SST Variations in the Indian Ocean Dipole Regions显示文摘By using a new heat budget equation that is closely related to the sea surface temperature (SST) and a dataset from an ocean general circulation model (MOM2) with 10-a integration (1987-1996), the relative importance of various processes determining SST variations in two regions of the Indian Ocean is compared. These regions are defined by the Indian Ocean Dipole Index and will be referred to hereafter as the eastern (0°-10°S, 90°-110°E) and western regions (10°S-10°N, 50°-70°E), respectively. It is shown that in each region there is a falling of SST in boreal summer and a rising in most months of other seasons, but the phases are quite different. In the eastern region, maximum cooling rate occurs in July,whereas in the western region it occurs in June with much larger magnitude. Maximum heating rate occurs in November in the eastern region, but in March in the western one. The western region exhibits another peak of increasing rate of SST in October, indicating a typical half-year period. Net surface heat flux and entrainment show roughly the same phases as the time-varying term, but the former has much larger contribution in most of a year, whereas the latter is important in the boreal summer. Horizontal advection, however, shows completely different seasonal variations as compared with any other terms in the heat budget equation. In the eastern region, it has a maximum in June/November and a minimum in March/September, manifesting a half-year period; in the western region, it reaches the maximum in August and the minimum in November. Further investigation of the horizontal advection indicates that the zonal advection has almost the opposite sign to the meridional advection. In the eastern region, the zonal advection is negative with a peak in August, whereas the meridional one is positive with two peaks in June and October. In the western region, the zonal advection is negative from March to November with two peaks in June and November, whereas the meridional one is positive with one peak in July.Different phases can be clearly seen between the two regions for each component of the horizontal advection. A detailed analysis of the data of 1994, a year identified when the Indian Ocean dipole event happened, indicates that the horizontal advection plays a dominant role in the remarkable cooling of the eastern region, in which zonal and meridional advections have the same sign of anomaly. However, in the western region in 1994 no any specialty was shown as compared with other years, for the SST anomaly is not positive in large part of this region. All these imply that the eastern and western regions may be related in a quite complex way and have many differences in dynamics. Further study is needed. | HU Ruijin LIU Qinyu LI Chongyin | 2005 | Journal of Ocean University of China2005，4，4： | 3 |
| 9 | Split liver transplantation: a reliable approach to expand donor pool显示文摘Orthotopic liver transplantation as a successful treatment of end-stage liver disease is hampered by a persistent lack of cadaveric organs. Split liver transplantation, which was first successfully performed by Medical School of Hannover in 1988, has become a mature surgical technique to expand the donor pool. Between 1993 and 1999, split liver transplantation activities have increased in Europe from 1. 2% to 10. 4% in all performed liver transplantations. Current data have strongly supported that the survival rate of patients after split liver transplantation is not significantly different from that of patients after whole-size orthotopic liver transplantation. The most important step of donor graft selection is surgeon’ s observation judged by the experience of individual transplant center. The paper aims to provide the guideline of donor selection, hepatic graft splitting, and recipient management as well. DATA SOURCES: Medical School of Hannover has accumulated plentiful experience of split liver transplantation for more than 10 cases ever since 1998. Besides that, we also reviewed a variety of literatures from other famous European and American centers specialized in this field for many years. RESULTS:According to our experience combined with the view points of others, the donor should meet the following criteria as well: (1) age less than 50 years; (2) hemodynamics stable; (3) ICU less than 5 days; (4) Na less than 170 mmol/L or better if less than 150 mmol/L. In 1996 and 1997, the Hamburg group and the UCLA group separately introduced a breakthrough technique performing split liver transplantation in situ. Evidently, the in situ technique has been limited by prolonged time of donor organ procurement , coordination with other organ procurement teams, and even extra burden on donor hospital. Some groups, therefore, have restored the ex situ or bench splitting technique , and fortunately the transplant outcomes of the ex situ technique are equivalent to those of the in situ one. Recently some new techniques have been introduced to split the liver for two adult patients, including the split-cava technique. CONCLUSIONS:It is clear that the most important factor for determining the prognosis of the patient is the time of receiving liver transplantation, not the type of liver transplantation. We still need to pay close attention to the graft to recipient weight ratio (GRWR) and the UNOS classification or MELD score before the patient is subjected to split liver transplantation. | Ji-Qi Yan, Thomas Becker, Cheng-Hong Peng, Hong-Wei Li and Juergen Klempnauer Department of Surgery, Ruijin Hospital Affiliated to Shanghai Second Medical University, Shanghai 200025, China ( Yan JQ, Peng CH and Li HW) Department of Abdominal and Transplant Surgery, Medical School of Hannover, Carl-Neuberg-Str. 1 , 30625 Hannover, Germany | 2005 | Hepatobiliary & Pancreatic Diseases International2005，4，3： | 3 |
| 10 | Magnetic resonance imaging of hepatocellular carcinoma induced by diethylnitrosamine in Sprague-Dawley rats显示文摘Diethylnitrosamine (DENA) is able to induce various benign and malignant liver lesions in rats with a high success rate and a low mortality rate. It provides a more appropriate model that better simulates the various lesions occurring in humans than the usual model of tumor implantations. The aim of the present study was to evaluate MRI liver examination in Sprague-Dawley(SD) rats as a routine method to detect hepatocellular carcinoma (HCC) nodules induced by DENA and to follow up their growth. METHODS:Hepatic carcinogenesis was induced in 80 male SD rats using oral DENA solution. All animals were imaged for liver tumor detection with a 1.5 Tesla magnet (Siemens Sonata,Erlangen, Germany) using correspondence scan parameters and a radio-frequency knee coil. Macroscopic examinations were performed along the axial MRI sections to evaluate magnetic resonance imaging (MRI) findings, and histopathological assessment was also performed. RESULTS:No false negative results were obtained on MR images. Hepatic tumors in 72 rats were confirmed macro-scopically and 68 rats were detected by MRI till the 20th week. The smallest and the largest nodules detected by MRI were 2 mm and 37 mm in diameter respectively. The agreement rate of MRI with macroscopic observation was 39. 1% and 97. 4% respectively for 2 mm to 5 mm and more than 5 mm nodules. CONCLUSIONS:The hepatic tumor induced by DENA provides a more representative range of tumors for imaging diagnosis and interventional treatment. MRI is the best approach for scrutinizing pathological changes of rat livers in the period of observation. | Department of Radiology, West China Hospital, Sichuan University, Chengdu 610041, China (Li X, Zhou XP and Guan YS) Department of Radiology, Ruijin Hospieal.

| 11 | Pancreatic insulinomas: diagnosis and surgical treatment of 74 patients显示文摘Objective: To summarize retrospectively the experi-ence in diagnosis and surgical treatment of pancreaticinsulinoma.Method: 74 patients who had been operated on andconfirmed pathologically from July 1967 to July 2001were enrolled. They were 37 men and 37 women,aged 41.91 years on average.Results: In all patients with typical Whipple’s triad,the ratio of insulin to glucose was measured over 0.3for at least one time. 52.70 % of the patients wereonce misdiagnosed, and only 20.27 % of them werecorrectly diagnosed in a year after onset of symp-toms. Their average course of the disease was 3.36years. B-ultrasonography and endoscopic ultrasonog-raphy (EUS) showed a low positive rate for localiza-tion of insulinoma. CT and magnetic resonance ima-ging (MRI) could correctly detected 63.41% and63.64 % of tumors respectively, in sharp contrast toa localization rate of 90 % for arterial stimulation andvenous sampling (ASVS). Single insulinoma was ob-served in 66 patients (89.19 %), multiple insulinomain 2 (2.70 %), hyperplasia in 4 (5.41%), and malig-nant insulinoma in 2 (2. 70%). Most (85. 29%) ofthe benign insnlinomas were less than 2 cm in diame-ter. Simple enucleation was the major operative pro-cedure for benign tumors. In 88. 52% of the pa-tients, glycemia increased to normal in 30 minutesafter tumor excision, and in the remaining patientswithin 2 hours. 97. 26% of the patients experiencedtemporary hyperglycemia but recovered in a week.The major complications of insnlinoma included pan-creatic fistulae (27.27 %) and pancreatitis (5. 19 %).Conclusions: Better recognization of insulinoma andits rational examination are essential to early diagno-sis. CT can be first used for localization, otherwiseASVS is used. Surgery is the major choice for thetreatment of insulinoma, but cautions should betaken to pancreatic fistulae after operation. | Xi Chen Wei-Yao Cai Wei-Ping Yang Hong-Wei Li the Department of Surgery, Ruijin Hospital, Shang-hai Second Medical University, Shanghai 200025, China | 2002 | Hepatobiliary & Pancreatic Diseases International2002，1，3： | 3 |
| 12 | Abdominal cluster transplantation and management of perioperative hemodynamic changes显示文摘BACKGROUND: Multivisceral transplantation (MTX, or cluster transplantation) is defined as the transplantation of three or more abdominal organs en bloc, namely the liver together with the pancreatoduodenal complex, the stomach as well as the small bowel with/without the right hemicolon. Up to May 1999, only 72 cases were reported to the Intestinal Transplant Registry. Organ cluster transplantation may carry with complex hemodynamic alterations. Based on our experience in two cases of abdominal cluster transplantation, we describe the technical details of multivisceral transplantation and the management of hemodynamic changes. METHODS: A Swan-Ganz catheter was placed to assist in monitoring the patients’ hemodynamic status. After the transplantation, the 2 patients were closely observed in the intensive care unit in terms of vital signs; disseminated intravascular coagulation (DIC) including activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), fibrinogen (Fg) and D-dimer, and arterial blood gas; and quantity and characteristics of drainage. Additionally, intra-abdominal hemorrhage was supervised by bedside B-ultrasonography or enhanced computed tomography (CT) examination. Whole blood viscosity was monitored 2 weeks after transplantation. The blood flow of the hepatic artery and portal vein and arterial resistant index were assessed routinely by Doppler ultrasonography. RESULTS: Hemodynamic changes were observed during perioperation. Liver and renal function recovered within one week after transplantation. Enteral feedings and oral intake were gradually increased with a reciprocal decrease in parenteral nutrition. Despite systemic antibiotics were given according to the results of frequent cultures, patient 1 died from cytomegalovirus (CMV) infection 4 months after transplantation and patient 2 died of a systemic sepsis 2 months after the operation. CONCLUSIONS: Many factors contribute to the success of multivisceral transplantation. In order to maintain hemodynamics stable during perioperation, preoperative coagulatory function should be corrected, and stable circulation, serum electrocyte balance, and normal body temperature should be kept during the operation in addition to the treatment of intra-abdominal hemorrhage and making up for the loss of body fluid. However, complicatiom, infection and rejection are barriers for the improvement of graft survival. | Hui-Xing Chen, Lu Yin, Cheng-Hong Peng, Guang-Wen Zhou, Bai-Yong Shen, Hao Chen, Chuan Shen and Hong-Wei Li Department of Surgery and Center of Organ Transplantation, Ruijin Hospital, Shanghai Second Medical University, Shanghai 200025, China | 2006 | Hepatobiliary & Pancreatic Diseases International2006，5，1： | 2 |
| 13 | Deep-red emitting Mg2Ti04:Mn^(4+)phosphor ceramics for plant lighting显示文摘In this study,deep-red emitting Mg2T i04:Mn4 phosphor ceramics were synthesized by the high temperature solid-state reaction method.The ceramics can be excited by the 465 nm blue light and had a narrow emission with a full width at half maximum(FWMH)value of 31 nm.The peak wavelength was located at 658 nm,which matched the demanded wavelength for photosynthesis.The crystal field strength(Dq)and the Racah parameters(B and C)were estimated by the Tanabe-Sugano diagram.The thermal conductivity of the Mg2Ti(0.999)O4:0.001Mn^(4+)ceramic was 7.535 W/(m·K)at room temperature,which was one order of magnitude higher than that of the traditional packaging method using the silicone gel.A set of phosphor converted LEDs were fabricated by mounting the phosphor ceramics onto the 460 nm blue LED chips and the CIE coordinates can move from the blue region to the purple light region with the thickness of the ceramic increasing.These results indicated that the Mg2Ti04:Mn^(4+)phosphor ceramic was suitable for plant lighting when combined with a blue LED chip. | Zixin WANG Hui LIN Dawei ZHANG Yiming SHEN Yang LI Ruijin HONG Chunxian TAO Zhaoxia HAN Lei CHEN Shengming ZHOU | 2021 | Journal of Advanced Ceramics2021，10，1： | 2 |
| 14 | Liver regeneration after split liver transplantation显示文摘BACKGROUND: The number of split liver transplantations (SLT) has increased in the last 5 years. Regeneration after the loss of hepatic tissue is a fundamental response to liver injury. Because partial-liver grafts may not be an optimal size for recipients, the purpose of this study was to investigate the regeneration of graft liver after SLT. METHODS: Four recipients have undergone SLT at our hospital since 2002. The graft liver volume (GLV) in the postoperative day ( POD) was measured by computed tomography (CT) and the serum levels of aspartate amino-transferase (AST) , alanine aminotransferase (ALT) , total bilirubin ( TB ), prealbumin ( PA ) and albumin ( ALB ) were monitored. The GLV at different postoperative times was compared to the recipient’ s standard liver volume ( SLV) and the liver volume regeneration ratio ( LVRR) was calculated. In order to compare SLV in recipient 2, we measured the total liver volume including the graft and the residual native liver as the GLV. RESULTS: The GLV/SLV at POD120 and POD360 of recipient 1 was measured 114% (1159.32 cm3 71016.95 cm3) , 97% (986.44 cm371016.95 cm3 ) with the LVRR being -11.0%, -24.3%, respectively. For recipient 2, it was measured 96% (927.32 cm3 7965.96 cm3) and 100% (968. 98 cm37965. 96 cm3 ) , with the LVRR being 24. 4% , 30. 0% , respectively. The initial graft volume of segment Ⅱ ,Ⅲ was 265.36 cm3 and increased to 335.24 cm3 and 360.56 cm3 at POD120 and POD360, respectively, with the LVRR being 26.3% and 35.9%, respectively. The GLV/SLV at POD60 of recipient 3 was 86% (893. 04 cm3/ 1038. 42 cm3 ) and the LVRR was 12. 0%. For recipient 4, it was 90% (567. 48 cm3/630. 54 cm3 ) whereas the LVRR was 20. 0%. The serum levels of ALT, AST and TB in all recipients declined gradually and returned to normal while the serum levels of PA and ALB increased to normal. The serum levels of ALT and AST peaked within 3 days after SLT. The neurological symptoms of Wilson ’s disease in recipient 2 were improved markedly. The levels of serum copper and copper-protein decreased to 30 mg/L, 120 mg/L at POD 120 and the Kayser-Fleischer rings began to obliterate. CONCLUSIONS: The size of the transplanted liver after SLT tends to converge to the standard liver volume with time and it is adequate clinically for SLT to meet the need of the body’s metabolic demands. The functional recovery of the graft liver occurs earlier than the morphological restoration. | Hui-Xing Chen, Guang-Wen Zhou,Lu Yin,Cheng-Hong Peng and Hong-Wei Li Shanghai, China Department of Surgery and Center of Organ Transplantation, Ruijin Hospital, Shanghai Second Medical University, Shanghai 200025,China | 2005 | Hepatobiliary & Pancreatic Diseases International2005，4，4： | 2 |
| 15 | Non-destructive testing method of microdebonding defects in composite insulation based on high power ultrasonic显示文摘It is crucial to ensure the adhesive quality of the interface in composite insulation equipment for power grid security.Due to viscoelasticity of silicone rubber and roughness of interface,the thickness of the local air layer in the defective interface is<100μm.This kind of defect is called micro-debonding defect in this paper,and it is significantly smaller than the millimetre-scale air gaps which could be defected by the x-ray,THz,and traditional ultrasonic method.It remains challenging to detect the micro-debonding in composite insulation by non-destructive testing methods.In this paper,the acoustic model and bi-linear stiffness model for micro-debonding in different stages are established.Accordingly,a conjecture is proposed that the bonding property of composite insulation is related to the acoustic impedance of interface and non-linear distortion of its constitutive relation.The result obtained from numerical simulation with and without defect is compared with the high-power ultrasonic experimental data to validate the correctness of the theoretical model.In addition,it can be concluded that the non-linear distortion of high-power ultrasonic wave can be effectively used to diagnose micro-debonding defect at the interface of composite insulation in its early stage(1-20μm). | Hanqing Wang Li Cheng Ruijin Liao Sida Zhang Lijun Yang | 2019 | High Voltage2019，4，3： | 2 |

| 20 | Study on the detection method of holes in composite insulator rods显示文摘The holes in composite insulator rods are a type of quality defects.However,not all holes can be identified by the dye penetration test according to existing standards and some holes can cause abnormal heating of the composite insulator during operation.Micro‐computed tomography is used to study the structure of these holes.Based on the pore structure,the holes are classified as dependent or independent.The dependent hole is formed by several interconnected adjacent pores and the overlong equivalent penetration path makes it cannot be effectively identified by the standard dye penetration test.Considering the structure of the dependent hole,ethanol gas was used to increase the effectiveness of the dye penetration test.The experimental results show that the detection rate of dependent holes is approximately 80%as the ethanol concentration is close to saturation,and the porosity can be inferred based on the number of penetration points. | Sida Zhang Li Cheng Yunfan Liu Ruijin Liao Tingting Wang Huan Huang | 2021 | High Voltage2021，6，5： | 1 |
