| 3 | Transcatheter arterial chemoembolization followed by immediate radiofrequency ablation for large solitary hepatocellular carcinomas显示文摘AIM: To assess the technical safety and efficacy of transcatheter arterial chemoembolization (TACE) combined with immediate radiofrequency ablation (RFA) for large hepatocellular carcinomas (HCC) (maximum diameter ≥ 5 cm). METHODS: Individual lesions in 18 patients with HCCs (mean maximum diameter: 7.5 cm; range: 5.1-15.5 cm) were treated by TACE combined with percutaneous RFA between January 2010 and June 2012. All of the patients had previously undergone one to four cycles of TACE treatment. Regular imaging and laboratory tests were performed to evaluate the rate of technical success, technique-related complications, local-regional tumor responses, recurrence-free survival time and survival rate after treatment.RESULTS: Technical success was achieved for all 18 visible HCCs. Complete response (CR) was observed in 17 cases, and partial response was observed in 1 case 1 mo after intervention. The CR rate was 94.4%. Local tumors were mainly characterized by coagulative necrosis. During follow-up (2-29 mo), the mean recurrencefree survival time was 16.8 ± 4.0 mo in 17 cases of CR. The estimated overall survival rate at 6, 12, and 18 mo was 100%. No major complications were observed. Levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the blood of 17 patients transiently increased on the third day after treatment (ALT 200.4 ± 63.4 U/L vs 24.7 ± 9.3 U/L, P < 0.05; AST 228.1 ± 25.4 U/L vs 32.7 ± 6.8 U/L, P < 0.05). Severe pain occurred in three patients, which was controlled with morphine and fentanyl. CONCLUSION: TACE combined with immediate RFA is a safe and effective treatment for large solitary HCCs. Severe pain is a major side effect, but can be controlled by morphine. | Zhi-Jun Wang Mao-Qiang Wang Feng Duan Peng Song Feng-Yong Liu Zhong-Fei Chang Yan Wang Jie-Yu Yan Kai Li | 2013 | World Journal of Gastroenterology2013,19,26: | 24 |
| 4 | Holocene high lake-levels and pan-lake period on Badain Jaran Desert显示文摘Many lakes exist in southeastern Badain Jaran Desert and its hinterland, including 110 perennial lakes and some seasonal or extinct lakes. Geomorphological, sedimentological, and bioglyph evidence obtained from field investigations on Badain Jaran Desert lake group, alongside measurements and dating performed on lake relic, prove that these lakes expanded while the climate was relatively wet during early and middle Holocene. The dating results suggest that the pan-lake period of the Badain Jaran Desert began at 10 cal kyr BP, before which the limnic peat period occurred(11–10 cal kyr BP). Many lakes reached their maximal water-level during 8.6–6.3 cal kyr BP and retreated or dried up in the late Holocene(about 3.5–0 cal kyr BP). During that period, the precipitation at Badain Jaran Desert may have reached 200 mm yr^(-1) for 7.7–5.3 cal kyr BP, inferred from both the age and precipitation rate of calcareous root tubes. The water balance calculation shows that wetter and warmer climate and the increase of underground water recharge were key factors in maintaining and developing the lake group at both centennial and millennial time scales. Furthermore, lake surface expansion and the increasing fresh water availability set the background for the prosperous prehistoric culture. | WANG NaiAng NING Kai LI ZhuoLun WANG YiXin JIA Peng MA Ling | 2016 | Science China Earth Sciences2016,59,8: | 19 |
| 5 | YAP promotes osteogenesis and suppresses adipogenic differentiation by regulatingβ-catenin signaling显示文摘YAP(yes-associated protein) is a transcriptional factor that is negatively regulated by Hippo pathway, a conserved pathway for the development and size control of multiple organs. The exact function of YAP in bone homeostasis remains controversial. Here we provide evidence for YAP's function in promoting osteogenesis, suppressing adipogenesis, and thus maintaining bone homeostasis.YAP is selectively expressed in osteoblast(OB)-lineage cells. Conditionally knocking out Yap in the OB lineage in mice reduces cell proliferation and OB differentiation and increases adipocyte formation, resulting in a trabecular bone loss. Mechanistically, YAP interacts with β-catenin and is necessary for maintenance of nuclear β-catenin level and Wnt/β-catenin signaling. Expression of β-catenin in YAP-deficient BMSCs(bone marrow stromal cells) diminishes the osteogenesis deficit. These results thus identify YAP-β-catenin as an important pathway for osteogenesis during adult bone remodeling and uncover a mechanism underlying YAP regulation of bone homeostasis. | Jin-Xiu Pan Lei Xiong Kai Zhao Peng Zeng Bo Wang Fu-Lei Tang Dong Sun Hao-han Guo Xiao Yang Shun Cui Wen-Fang Xia Lin Mei Wen-Cheng Xiong | 2018 | Bone Research2018,6,2: | 19 |

| 7 | Wheel/rail dynamic interaction due to excitation of rail corrugation in high-speed railway显示文摘Characteristics of wheel-rail dynamic interaction due to the rail corrugation in a high-speed railway are analyzed based on the theory of vehicle-track coupled dynamics in this paper.Influences of the corrugation wavelength and depth on the wheel-rail dynamic performance are investigated.The results show that,under the excitation of a measured rail corrugation,the wheel-rail dynamic interaction of high-speed railway is enhanced obviously,and the high-frequency dynamic force between wheel and rail is generated,which has an obvious impact on the vibrations of the wheelset and rail,and little effect on the vibration of the frame and carbody.If the corrugation wavelength is shorter than the sensitive wavelength,the wheel-rail vertical force will increase with the growth of the corrugation wavelength,otherwise,it will decrease.However,the wheel-rail vertical force keeps increasing with the growth of corrugation depth.Furthermore,if the corrugation wavelength is shorter than the sensitive wavelength,the wheel-rail vertical force will increase with the decrease of the running speed,otherwise,it will decrease.It is also found that the critical wavelength of corrugation increases with the growth of the corrugation depth and the running speed,and the critical depth of corrugation is nonlinearly related to the sensitive wavelength. | WANG Kai Yun LIU Peng Fei ZHAI Wan Ming HUANG Chao CHEN Zai Gang GAO JianMin | 2015 | Science China(Technological Sciences)2015,58,2: | 17 |
| 8 | Surgical treatment for hepatocellular carcinoma and secondary hypersplenism显示文摘BACKGROUND: Hepatocellular carcinoma (HCC) is a common disease with high mortality and serious effect on the life quality of patients. Operation is still the most effective treatment. Currently, in China, patients with HCC are often complicated by hepatitis B related liver cirrhosis and secondary hypersplenism. This study was undertaken to evaluate the effect and indications of synchronous hepatectomy and splenectomy for HCC patients with hypersplenism. METHODS: The clinical records and treating processes of 24 patients with HCC and hypersplenism during the period of January 1991 to July 2004 were analyzed retrospectively. RESULTS: Sixteen patients underwent hepatectomy and splenectomy, including extensive devascularizasion around the cardia (9 patients). Seven patients were treated with microwave ablation and splenectomy plus extensive esophagogastric devascularization. One patient underwent hepatectomy combined with microwave ablation and splenectomy plus extensive esophagogastric devascularization. There were no deaths during the operation. During the first week after operation, the symptoms of hypersplenism disappeared and the platelet (Plt) and white blood cell (WBC) counts were significantly elevated (Plt: 247×109/L vs. 45.9×109/L, WBC: 13.0×109/L vs.3.3×109/L,P<0.01). CONCLUSIONS: Synchronous splenectomy can increase the safety of hepatectomy in selected patients with HCC and secondary hypersplenism by reducing bleeding complications. Splenectomy enhances patients’ immunity against tumor in a long period as well. | Qian Wang, Kai Sun, Xiang-Hong Li, Bao-Gang Peng and Li-Jian Liang Department of Hepatobiliary Surgery, First Affiliated Hospital, Sun Yat-Sen University, Guangzhou 510080, China | 2006 | Hepatobiliary & Pancreatic Diseases International2006,5,3: | 14 |
| 9 | Analysis of vibration reduction characteristics and applicability of steel-spring floating-slab track显示文摘A coupled dynamics computation model for metro vehicles,along with a steel-spring floating-slab track,is developed based on the theory of vehicle-track coupled dynamics.Using the developed model,the influences of the thickness,length and mass of floating-slab,spring rate and its arrangement space,running speed,etc.on the time and frequency domain characteristics of steel-spring fulcrum force are analyzed.The applicability of steel-spring floating-slab track is discussed through two integrated example cases of metro and buildings possessing distinct natural vibra-tion characteristics.It is concluded that,it is quite significant,in the optimization modular design of the parameters of steel-spring floating-slab track,to take the matching relationship of both the amplitude-frequency characteristics of steel-spring fulcrum force and natural vibration characteristics of integrated structures into comprehensive considera-tion.In this way the expensive steel-spring floating-slab track can be economically and efficiently utilized according to the site condition,and at the same time,the economic losses and bad social impact resulted from the resonance during usage of steel-spring floating-slab track can be avoided. | Wanming ZHAI Peng XU Kai WEI | 2011 | Journal of Modern Transportation2011,19,4: | 14 |

| 11 | Immunohistochemical study of hepatic oval cells in human chronic viral hepatitis显示文摘AIM To detect immunohistochemically the presence of oval cells in chronic viral hepatitis with antibody against c-kit.METHODS We detected oval cells in paraffin-embedded liver sections of 3 normal controls and 26 liver samples from patients with chronic viral hepatitis, using immunohistochemistry with antibodies against c-kit, π-class glutathione Stransferase ( Tr-GST ) and cytokeratins 19(CK19).RESULTS Oval cells were not observed in normal livers. In chronic viral hepatitis, hepatic oval cells were located predominantly in the periportal . region and fibrosis septa,characterized by an ovoid nucleus, small size,and scant cytoplasm. Antibody against stem cell factor receptor, c-kit, had higher sensitivity and specificity than π-GST and CK19. About 50% -70% of c-kit positive oval cells were stained positively for either π-GST or CK19.CONCLUSION Oval cells are frequently detected in human livers with chronic viral hepatitis, suggesting that oval cell proliferation is associated with the liver regeneration in this condition. | Xiong Ma De Kai Qiu Yan Shen Peng Shanghai Institute of Digestive Diseases, Renji Hospital, Shanghai Second Medical University, Shanghai 200001, China | 2001 | World Journal of Gastroenterology2001,7,2: | 13 |

| 13 | Comparison of breast-conserving surgery and mastectomy in early breast cancer using observational data revisited:a propensity score-matched analysis显示文摘Recent observational studies showed that breast-conserving surgery(BCS) resulted in superior survival compared to mastectomy in breast cancer patients. This study compared the clinical outcomes of BCS and mastectomy using propensity score(PS)matching analysis, which had advantages over conventional methods in reducing bias. Nonmetastatic breast cancer patients who underwent BCS and mastectomy were matched 1:1 based on their PS. We used the Kaplan-Meier method and Cox-regression model to estimate the treatment effects. A total of 2,866 patients with a median follow-up time of 67 months were included in the original study population. Although the mastectomy cohort(N=1,219) had more advanced disease compared to the BCS cohort(N=1,647), LRFS was similar between the two groups(93.8% vs. 92.4%, P>0.05). BCS(vs. mastectomy) was associated with improved DFS(73.8% vs. 58.7%, P<0.01) and CSS(91% vs. 78.2%, P<0.01) in the original population. In the PS-matched population(N=1,668), clinicopathological features were equally distributed between the two cohorts. BCS(vs. mastectomy) was not associated with improved DFS(70.7% vs. 66.9%, P>0.05) or CSS(87.5% vs. 84.9%, P>0.05). We found that PS methods reduce bias when estimating treatment effects using observational data. BCS and mastectomy show equivalent outcomes in nonmetastatic breast cancer patients. | Kai Chen Zihao Pan Liling Zhu Tingting Hu Min Peng Weijuan Jia Fengxi Su Shunrong Li Erwei Song | 2018 | Science China(Life Sciences)2018,61,12: | 12 |
| 14 | Circular RNA circVAPA promotes chemotherapy drug resistance in gastric cancer progression by regulating miR-125b-5p/STAT3 axis显示文摘BACKGROUND Gastric cancer(GC)is a prevalent malignancy,leading to a high incidence of cancer-associated death.Cisplatin(DDP)-based chemotherapy is the principal therapy for clinical GC treatment,but DDP resistance is a severe clinical challenge and the mechanism remains poorly understood.Circular RNAs(circRNAs)have been identified to play crucial roles in modulating the chemoresistance of gastric cancer cells.AIM To explore the effect of circVAPA on chemotherapy resistance during GC progression.METHODS The effect of circVAPA on GC progression and chemotherapy resistance was analyzed by MTT assay,colony formation assay,Transwell assay,wound healing assay,and flow cytometry analysis in GC cells and DDP resistant GC cell lines,and tumorigenicity analysis in nude mice in vivo.The mechanism was investigated by luciferase reporter assay,quantitative real-time PCR,and Western blot analysis.RESULTS CircVAPA expression was up-regulated in clinical GC tissues compared with normal samples.CircVAPA depletion inhibited proliferation,migration,and invasion and increased apoptosis of GC cells.The expression of circVAPA,STAT3,and STAT3 downstream genes was elevated in DDP resistant SGC7901/DDP cell lines.CircVAPA knockdown attenuated the DDP resistance of GC cells.Mechanically,circVAPA was able to sponge miR-125b-5p,and miR-125b-5p could target STAT3 in the GC cells.MiR-125b-5p inhibitor reversed circVAPA depletion-enhanced inhibitory effect of DDP on GC cells,and STAT3 knockdown blocked circVAPA overexpression-induced proliferation of DDPtreated SGC7901/DDP cells.The depletion of STAT3 and miR-125b-5p inhibitor reversed circVAPA depletion-induced GC cell apoptosis.Functionally,circVAPA contributed to the tumor growth of SGC7901/DDP cells in vivo.CONCLUSION CircVAPA promotes chemotherapy resistance and malignant progression in GC by miR-125b-5p/STAT3 signaling.Our findings present novel insights into the mechanism by which circVAPA regulates chemotherapy resistance of GC cells.CircVAPA and miR-125b-5p may be considered as the potential targets for GC therapy. | Peng Deng Ming Sun Wen-Yan Zhao Bin Hou Kai Li Tao Zhang Feng Gu | 2021 | World Journal of Gastroenterology2021,27,6: | 11 |
| 15 | Diagnostic value of elevated serum carbohydrate antigen 199 level in acute cholangitis secondary to choledocholithiasis显示文摘AIM To investigate the diagnostic value of abnormal serum carbohydrate antigen 199(CA199) level in acute cholangitis secondary to choledocholithiasis.METHODS In this retrospective cohort study, the clinical data of 727 patients with choledocholithiasis admitted to the Third Affiliated Hospital of Zunyi Medical College from June 2011 to June 2017 were collected. Among these patients, 258 patients had secondary acute cholangitis and served as observation group, and the remaining 569 choledocholithiasis patients served as the control group. Serum liver function indexes and tumor markers were detected in both groups, and the receiver operating characteristic(ROC) curves were constructed for markers showing statistical significances. The cutoff value, sensitivity, and specificity of each marker were calculated according to the ROC curves. RESULTS The results of liver function tests showed no significant differences between the two groups(P > 0.05). Tumor markers including serum CA125, CA153, carcinoembryonic antigen, and alpha fetoprotein levels were also not significantly different(P > 0.05); however, the serum CA199 level was significantly higher in the observation group than in the control group(P < 0.05). The ROC curve analysis showed that the area under the curve was 0.885(95%CI: 0.841-0.929) for CA199, and the cutoff value of 52.5 kU/L had the highest diagnostic accuracy, with a sensitivity of 86.8% and a specificity of 81.6%.CONCLUSION Abnormally elevated serum CA199 level has an important value in the diagnosis of acute cholangitis secondary to choledocholithiasis. It may be a specific inflammatory marker for acute cholangitis. | Yong Mei Li Chen Ci-Jun Peng Jun Wang Peng-Fei Zeng Guo-Xing Wang Wen-Ping Li Yan-Qing Luo Chao Du Kai Liu Kun Xiong Kai Leng Chun-Lin Feng Ji-Hu Jia | 2018 | World Journal of Clinical Cases2018,6,11: | 11 |
| 16 | Retrospective evaluation of lymphatic and blood vessel invasion and Borrmann types in advanced proximal gastric cancer显示文摘BACKGROUND The Borrmann classification system is used to describe the macroscopic appearance of advanced gastric cancer,and Borrmann typeⅣdisease is independently associated with a poor prognosis.AIM To evaluate the prognostic significance of lymphatic and/or blood vessel invasion(LBVI)combined with the Borrmann type in advanced proximal gastric cancer(APGC).METHODS The clinicopathological and survival data of 440 patients with APGC who underwent curative surgery between 2005 and 2012 were retrospectively analyzed.RESULTS In these 440 patients,LBVI+status was associated with Borrmann typeⅣ,low histological grade,large tumor size,and advanced pT and pN status.The 5-year survival rate of LBVI+patients was significantly lower than that of LBVI– patients,although LBVI was not an independent prognostic factor in the multivariate analysis.No significant difference in the prognosis of patients with Borrmann typeⅢ/LBVI+disease and patients with Borrmann typeⅣdisease was observed.Therefore,we proposed a revised Borrmann typeⅣ(r-BorⅣ)as Borrmann typeⅢplus LBVI+,and found that r-BorⅣwas associated with poor prognosis in patients with APGC,which outweighed the prognostic significance of pT status.CONCLUSION LBVI is related to the prognosis of APGC,but is not an independent prognostic factor.LBVI status can be used to differentiate Borrmann typesⅢandⅣ,and the same approach can be used to treat r-BorⅣand Borrmann typeⅣ. | Shan Gao Guo-Hui Cao Peng Ding Yang-Yang Zhao Peng Deng Bin Hou Kai Li Xiao-Fang Liu | 2019 | World Journal of Gastrointestinal Oncology2019,11,8: | 11 |

| 18 | Combination of mild therapeutic hypothermia and adipose-derived stem cells for ischemic brain injury显示文摘Mild therapeutic hypothermia has been shown to mitigate cerebral ischemia, reduce cerebral edema, and improve the prognosis of patients with cerebral ischemia. Adipose-derived stem cell-based therapy can decrease neuronal death and infiltration of inflammatory cells, exerting a neuroprotective effect. We hypothesized that the combination of mild therapeutic hypothermia and adipose-derived stem cells would be neuroprotective for treatment of stroke. A rat model of transient middle cerebral artery occlusion was established using the nylon monofilament method. Mild therapeutic hypothermia(33°C) was induced after 2 hours of ischemia. Adipose-derived stem cells were administered through the femoral vein during reperfusion. The severity of neurological dysfunction was measured by a modified Neurological Severity Score Scaling System. The area of the infarct lesion was determined by 2,3,5-triphenyltetrazolium chloride staining. Apoptotic neurons were detected by terminal deoxynucleotidyl transferase-mediated d UTP-biotin nick end labeling(TUNEL) staining. The regeneration of microvessels and changes in the glial scar were detected by immunofluorescence staining. The inflammatory responses after ischemic brain injury were evaluated by in situ staining using markers of inflammatory cells. The expression of inflammatory cytokines was measured by reverse transcription-polymerase chain reaction. Compared with mild therapeutic hypothermia or adipose-derived stem cell treatment alone, their combination substantially improved neurological deficits and decreased infarct size. They synergistically reduced the number of TUNEL-positive cells and glial fibrillary acidic protein expression, increased vascular endothelial growth factor levels, effectively reduced inflammatory cell infiltration and down-regulated the m RNA expression of the proinflammatory cytokines interleukin-1β, tumor necrosis factor-α and interleukin-6. Our findings indicate that combined treatment is a better approach for treating stroke compared with mild therapeutic hypothermia or adipose-derived stem cells alone. | Kai Zhao Rui Li Sheng Bi Yu Li Long Liu Yu-Long Jia Peng Han Chang-Cong Gu Xi-Ze Guo Wan-Ping Zhang Chun Wang Chun-Ying Pei Lin-Lu Tian Li-Xian Li | 2018 | Neural Regeneration Research2018,13,10: | 9 |
| 19 | Stress and deformation analysis on deep surrounding rock at different time stages and its application显示文摘Based on the characteristics of the deep circular tunnel, the surrounding rock was divided into three regions: the cracked region, the plastic region and the viscoelastic region. The process of rock stress deformation and change was divided into three stages after the roadway excavation. By using the elastic-plastic mechanics theory, the analytical solutions of the surrounding stress and displacement at different stages and the radii of cracked and plastic regions were formulated. We additionally explained the surrounding rock stress and displacement which appeared in practical project. Simultaneously, based on the problem which emerged from a mine in Xuzhou during the excavating process of rock roadway's transport, we got the theoretical solutions for the stress and displacement in the process of rock roadway's excavation and considered that the broken area of rock roadway was largely loosing circle. The results indicate that according to the rheological characteristics of surrounding rock, in the primeval excavation of rock roadway, we should increase the length of anchor bolt and cooperate it with anchor nets cable-U steel supporting frame. In addition, when the deformation rate of the surrounding rock is descending after the 15 days' excavation, we should use the ''three anchor'' supporting method (anchor bolt spray, anchor note and anchor rope) and set aside about 20 cm as the reserved deformation layer. | Li Ming Mao Xianbiao Yu Yuanlin Li Kai Ma Chao Peng Yan | 2012 | International Journal of Mining Science and Technology2012,22,3: | 9 |
| 20 | The gut microbial metabolite, 3,4-dihydroxyphenylpropionic acid, alleviates hepatic ischemia/reperfusion injury via mitigation of macrophage pro-inflammatory activity in mice显示文摘Hepatic ischemia/reperfusion injury(HIRI) is a serious complication that occurs following shock and/or liver surgery. Gut microbiota and their metabolites are key upstream modulators of development of liver injury. Herein, we investigated the potential contribution of gut microbes to HIRI.Ischemia/reperfusion surgery was performed to establish a murine model of HIRI. 16 S r RNA gene sequencing and metabolomics were used for microbial analysis. Transcriptomics and proteomics analysis were employed to study the host cell responses. Our results establish HIRI was significantly increased when surgery occurred in the evening(ZT12, 20:00) when compared with the morning(ZT0, 08:00);however, antibiotic pretreatment reduced this diurnal variation. The abundance of a microbial metabolite3,4-dihydroxyphenylpropionic acid was significantly higher in ZT0 when compared with ZT12 in the gut and this compound significantly protected mice against HIRI. Furthermore, 3,4-dihydroxyphenylpropionic acid suppressed the macrophage pro-inflammatory response in vivo and in vitro. This metabolite inhibits histone deacetylase activity by reducing its phosphorylation. Histone deacetylase inhibition suppressed macrophage pro-inflammatory activation and diminished the diurnal variation of HIRI. Our findings revealed a novel protective microbial metabolite against HIRI in mice. The potential underlying mechanism was at least in part, via 3,4-dihydroxyphenylpropionic acid-dependent immune regulation and histone deacetylase(HDAC) inhibition in macrophages. | Rui Li Li Xie Lei Li Xiaojiao Chen Tong Yao Yuanxin Tian Qingping Li Kai Wang Chenyang Huang Cui Li Yifan Li Hongwei Zhou Neil Kaplowitz Yong Jiang Peng Chen | 2022 | Acta Pharmaceutica Sinica B2022,12,1: | 8 |
