| 1 | Prognostic significance of expression of cyclooxygenase-2 and vascular endothelial growth factor in human gastric carcinoma显示文摘AIM: To investigate the role of cyclooxygenase-2(COX-2)and vascular endothelial growth factor (VEGF) in the development of gastric carcinoma and correlation between expression of COX-2 and VEGF and clinicopathologic features in tissues from patients with gastric carcinoma.METHODS: 281 patients with gastric carcinoma who underwent surgical resection between 1990 and 1999 at the First Affiliated Hospital, Anhui Medical University, PRC, were followed up. Expression of COX-2 and VEGF was investigated retrospectively in 232 gastric carcinoma tissues and 60noncancerous specimens by using immunohistochemistry.RESULTS: The 5-year survival rates of early gastric carcinoma (EGC) and advanced gastric carcinoma (AGC) were 93.4 %and 59.0 %, respectively. Survival time was highly correlated with lymph node metastasis, vascular invasion, depth of invasion and treatment with chemotherapy. Compared with paired noncancerous tissues, expression of COX-2 and VEGF and microvessel density (MVD) value in carcinoma tissue were significantly higher. The MVD value was much higher in COX-2-positive group and VEGF-positive group than that in COX-2-negative group and VEGF-negative group.Expression of COX-2 and VEGF, as well as MVD value were highly correlated with lymph node metastasis and vascular invasion. The 5-year survival rate of patients with expression of COX-2 or VEGF was significantly lower than that of patients without COX-2 or VEGF expression. Multivariate analysis revealed that VEGF overexpression, lymph node metastasis,COX-2 overexpression, depth of invasion and vascular invasion were all independent prognostic factors of gastric carcinoma.CONCLUSION: Overexpression of COX-2 and VEGF in patients with gastric carcinoma can enhance the possibility of invasion and metastasis, implicating a poor prognosis.They may serve as the fairly good prognostic factors to indicate biologic behaviors of gastric carcinoma. | Hai Shi Jian-Ming Xu Nai-Zhong Hu Hui-Jun Xie Department of Gastroenterology,the First Affiliated Hospital,Anhui Medical University,Hefei 23022,Anhui Province,China | 2003 | World Journal of Gastroenterology2003，9，7： | 64 |
| 2 | Fast-track surgery could improve postoperative recovery in radical total gastrectomy patients显示文摘AIM: To assess the impact of fast-track surgery (FTS) on hospital stay, cost of hospitalization and complications after radical total gastrectomy. METHODS: A randomized, controlled clinical trial was conducted from November 2011 to August 2012 in the Department of Digestive Surgery, Xijing Hospital of Digestive Diseases, the Fourth Military Medical University. A total of 122 gastric cancer patients who met the selection criteria were randomized into FTS and conventional care groups on the first day of hospitalization. All patients received elective standard D2 total gastrectomy. Clinical outcomes, including duration of flatus and defecation, white blood cell count, postoperative pain, duration of postoperative stay, cost of hospitalization and complications were recorded and evaluated.Two specially trained doctors who were blinded to the treatment were in charge of evaluating postoperative outcomes, discharge and follow-up. RESULTS: A total of 119 patients finished the study, including 60 patients in the conventional care group and 59 patients in the FTS group. Two patients were excluded from the FTS group due to withdrawal of consent. One patient was excluded from the conventional care group because of a non-resectable tumor. Compared with the conventional group, FTS shortened the duration of flatus (79.03 ± 20.26 hvs 60.97 ± 24.40 h, P = 0.000) and duration of defecation (93.03 ± 27.95 h vs 68.00 ± 25.42 h, P = 0.000), accelerated the decrease in white blood cell count [P < 0.05 on postoperative day (POD) 3 and 4], alleviated pain in patients after surgery (P < 0.05 on POD 1, 2 and 3), reduced complications (P < 0.05), shortened the duration of postoperative stay (7.10 ± 2.13 dvs 5.68 ± 1.22 d,P = 0.000), reduced the cost of hospitalization (43783.25 ± 8102.36 RMBvs 39597.62 ± 7529.98 RMB,P = 0.005), and promoted recovery of patients. CONCLUSION: FTS could be safely applied in radical total gastrectomy to accelerate clinical recovery of gastric cancer patients. | Fan Feng Gang Ji Ji-Peng Li Xiao-Hua Li Hai Shi Zheng-Wei Zhao Guo-Sheng Wu Xiao-Nan Liu Qing-Chuan Zhao | 2013 | World Journal of Gastroenterology2013，19，23： | 44 |

| 5 | Epidemiology of Diabetes in Adults Aged 35 and Older from Shanghai,China显示文摘Objective This study aimed to investigate the epidemiology of diabetes in adults from Shanghai, aged 35 and older, in 2013. Methods We estimated the diabetes prevalence in a representative sample of 18,736 adults who were selected through a multistage stratified cluster sampling process. A standard questionnaire containing questions about demographic characteristics and lifestyle factors was distributed. After an overnight fast of at least 10 hours, a venous blood sample was collected from each participant. For each patient without a history of diabetes, another blood sample was drawn 120 min after an oral glucose tolerance test to identify undiagnosed diabetes and prediabetic condition. Results Among Shanghai residents aged 35 and above, the overall weighted prevalence of diabetes was 17.6% [95% confidence interval(CI): 16.4%-18.8%]. The prevalences were 19.3% in men and 15.8% in women as well as 19.1%, 15.4%, and 16.1% in urban, suburban, and rural residents, respectively. In addition, the weighted prevalence of prediabetes was 16.5%(95% CI: 15.3%-17.8%), with the prevalences of 16.5% in men, 16.6% in women, 15.2% in urban residents, 18.0% in suburban residents, and 18.5% in rural residents. Among all patients with diabetes, 68.1%(95% CI: 64.3%-71.6%) were aware of their status, 63.5%(95% CI: 60.0%-66.9%) received diabetes treatment, but only 35.1%(95% CI: 32.4%-37.8%) had adequate glycemic control. Conclusion In Shanghai, diabetes and prediabetes are highly prevalent. However, 1/3rd of diabetes cases are undiagnosed, and the rate of glycemic control is low. | RUAN Ye YAN Qing Hua XU Ji Ying YANG Qun Di YAO Hai Hong LI Rui SHI Yan | 2016 | Biomedical and Environmental Sciences2016，29，6： | 22 |

| 7 | Experimental study on the angle of repose of pulverized coal显示文摘An experimental study on the angle of repose(AoR)of pulverized coal with different particle sizes and different moisture contents(MC)was conducted.Three different measurement methods,free-base piling,fixed-base piling and sliding,were used.The data were analyzed by one-way and two-way analysis of variance.The results showed that the AoRs of pulverized coal with particle sizes smaller than 150 m were in the range of 30-50°.The characterization of the flowability of pulverized coal was some cohesiveness or true cohesiveness.The increase of MC will increase AoR and thus decrease the flowability of the powder.However,the particle size effect is bifurcated.Below a critical size,the decrease of particle size decreases the flowability;while above the critical size,the decrease of particle size increases the flowability.It was found that the value of the critical size strongly depends on the powder density.Moreover,the AoR dependence on particle size could be linked with the Geldart's particle classification.The critical size at the turning point is on the boundary between Group A and Group B in Geldart's classification diagram.Based on the experimental results,there is no significant cross interaction between particle size and MC.The AoRs measured by free-base method and fixed-base method are close,but both remarkably smaller than that measured by the sliding method. | Wei Wang Jiansheng Zhang Shi Yang Hai Zhang Hairui Yang Guangxi Yue | 2010 | Particuology2010，8，5： | 20 |

| 9 | Salt-responsive genes in rice revealed by cDNA microarray analysis显示文摘We used cDNA microarrays containing ~9,000 unigenes to identify 486 salt responsive expressed sequence tags (ESTs) (representing ~450 unigenes) in shoots of the highly salt-tolerant rice variety, Nona Bokra (Oryza sativa L. Ssp.Indica pv. Nona). Some of the genes identified in this study had previously been associated with salt stress. Howeverthe majority were novel, indicating that there is a great number of genes that are induced by salt exposure. Analysis of the salt stress expression profile data of Nona provided clues regarding some putative cellular and molecular processes that are undertaken by this tolerant rice variety in response to salt stress. Namely, we found that multiple transcription factors were induced during the initial salt response of shoots. Many genes whose encoded proteins are implicated in detoxification, protectant and transport were rapidly induced. Genes supporting photosynthesis were repressed and those supporting carbohydrate metabolism were altered. Commonality among the genes induced by salt exposure with those induced during senescence and biotic stress responses suggests that there are shared signaling pathways among these processes. We further compared the transcriptome changes of the salt-sensitive cultivar, IR28, with that of Nona rice. Many genes that are salt responsive in Nona were found to be differentially regulated in IR28. This study identified a large number of candidate functional genes that appear to be involved in salt tolerance and further examination of these genes may enable the molecular basis of salt tolerance to be elucidated. | Dai Yin CHAO Yong Hai LUO Min SHI Da LUO Hong Xuan LIN | 2005 | Cell Research2005，15，10： | 17 |

| 14 | Helminth infections and intestinal inflammation显示文摘Evidence from epidemiological studies indicates an inverse correlation between the incidence of certain immune-mediated diseases, including inflammatory bowel diseases (IBD), and exposure to helminths. Helminth parasites are the classic inducers of Th2 responses. The Th2-polarized T cell response driven by helminth infection has been linked to the attenuation of some damaging Th1 driven inflammatory responses, preventing some Th1-mediated autoimmune diseases in the host, including experimentally induced colitis. Helminth parasites (the porcine whipworm, Trichuris suis ) have been tested for treating IBD patients, resulting in clinical amelioration of the disease. As a result, there is a great deal of interest in the research community in exploring the therapeutic use of helminth parasites for the control of immune-mediated diseases, including IBD. However, recent studies have provided evidence indicating the exacerbating effects of helminths on bacterial as well as non-infectious colitis in animal models. Therefore, a better understanding of mechanisms by which helminths modulate host immune responses in the gut may reveal novel, more effective and safer approaches to helminth-based therapy of IBD. | Li Jian Wang Yue Cao Hai Ning Shi | 2008 | World Journal of Gastroenterology2008，14，33： | 10 |
| 15 | Mycoplasma pneumoniae Macrolide Resistance and MLVA Typing in Children in Beijing,China,in 2016:Is It Relevant?显示文摘Objective The aim of this study is to investigate the macrolide resistance rate and molecular type with multiple-locus variable-number tandem-repeat analysis(MLVA)of Mycoplasma pneumoniae of Beijing in 2016 in pediatric patients.Methods Real-time quantitative polymerase chain reaction(PCR)was used to identify M.pneumoniae,and MLVA was performed.The domain V of the 23 S rRNA was sequenced to detect macrolide-resistant point mutations.We also investigated the activities of antibiotics against M.pneumoniae isolates in vitro.Results The PCR detection rate of M.pneumoniae in children in Beijing was 40%,and the macrolide resistance rate was 66%.The A2063 G mutation in the 23 S rRNA V region is the dominant mutation(137/146,93.84%),whereas the A2064 G mutation is rare(9/146,6.16%).Seventy-three samples were typed successfully by MLVA typing,including 86.3%(63/73)were MLVA type 4-5-7-2,and 13.7%(10/73)were MLVA type 3-5-6-2.No other types were found.No strains were resistant to levofloxacin or tetracycline.Conclusion In 2016,a specific decrease in the macrolide resistance rate occurred in Beijing.The detection rate and macrolide resistance rate of outpatients are lower than those of inpatients.The A2063 G mutants M.pneumoniae have high levels of resistance to erythromycin and azithromycin.The primary MLVA type is 4-5-7-2,followed by 3-5-6-2.No other MLVA types were detected.No strains resistant to tetracycline or levofloxacin were found in vitro. | DOU Hai Wei TIAN Xiu Jun XIN De Li WEI Ran ZHOU Wei WANG Hong QIN Xuan Guang SHAO Jun Yan XU Bao Ping GE Li Xia SHI Da Wei | 2020 | Biomedical and Environmental Sciences2020，33，12： | 9 |
| 16 | Experimental study on operative methods of pancreaticojejunostomy with reference to anastomotic patency and postoperative pancreatic exocrine function显示文摘AIM:To assess the patency of pancreaticoenterostomy and pancreatic exocrine function after three surgical methods. METHODS: A pig model of pancreatic ductal dilation was made by ligating the main pancreatic duct. After 4 wk ligation, a total of 36 piglets were divided randomly into four groups. The piglets in the control group underwent laparotomy only; the others were treated by three anastomoses: (1) end-to-end pancreaticojejunostomy invagination (EEPJ); (2) end-to-side duct-to- mucosa sutured anastomosis (ESPJ); or (3) binding pancreaticojejunostomy (BPJ). Anastomotic patency was assessed after 8 wk by body weight gain, intrapancreatic ductal pressure, pancreatic exocrine function secretin test, pancreatography, and macroscopic and histologic features of the anastomotic site. RESULTS: The EEPJ group had significantly slower weight gain than the ESPJ and BPJ groups on postoperative weeks 6 and 8 (P < 0.05). The animals in both the ESPJ and BPJ groups had a similar body weight gain.Intrapancreatic ductal pressure was similar in ESPJ and BPJ. However, pressure in EEPJ was significantly higher than that in ESPJ and BPJ (P < 0.05). All three functional parameters, the secretory volume, the flow rate of pancreatic juice, and bicarbonate concentration, were significantly higher in ESPJ and BPJ as compared to EEPJ (P < 0.05). However, the three parameters were similar in ESPJ and BPJ. Pancreatography performed after EEPJ revealed dilation and meandering of the main pancreatic duct, and the anastomotic site exhibited a variable degree of occlusion, and even blockage. Pancreatography of ESPJ and BPJ, however, showed normal ductal patency. Histopathology showed that the intestinal mucosa had fused with that of the pancreatic duct, with a gradual and continuous change from one to the other. For EEPJ, the portion of the pancreatic stump protruding into the jejunal lumen was largely replaced by cicatricial fibrous tissue. CONCLUSION: A mucosa-to-mucosa pancreatico- jejunostomy is the best choice for anastomotic patency when compared with EEPJ. BPJ can effectively maintain anastomotic patency and preserve pancreatic exocrine function as well as ESPJ. | Ming-Dong Bai Liang-Qun Rong Lian-Chen Wang Hai Xu Rui-Fang Fan Pei Wang Xiao-Peng Chen Liu-Bin Shi Shu-You Peng | 2008 | World Journal of Gastroenterology2008，14，3： | 9 |
| 17 | Correlation of An Ultrasonic Scoring System and Intraoperative Blood Loss in Placenta Accreta Spectrum Disorders: A Retrospective Cohort Study显示文摘Objective This study aims to investigate the correlation of an ultrasonic scoring system with intraoperative blood loss(IBL) in placenta accreta spectrum(PAS) disorders.Methods A retrospective cohort study was conducted between January 2015 and November 2019.Clinical data for patients with PAS have been obtained from medical records. Generalized additive models were used to explore the nonlinear relationships between ultrasonic scores and IBL. Logistic regressions were used to determine the differences in the risk of IBL ≥ 1,500 m L among groups with different ultrasonic scores.Results A total of 332 patients participated in the analysis. Generalized additive models showed a significant positive correlation between score and blood loss. The amount of IBL was increased due to the rise in the ultrasonic score. All cases were divided into three groups according to the scores(low score group: ≤ 6 points, n = 147;median score group: 7-9 points, n = 126;and high score group: ≥ 10 points, n = 59). Compared with the low score group, the high score group showed a higher risk of IBL≥ 1,500 m L [odds ratio, 15.09;95% confidence interval(3.85, 59.19);P ≤ 0.001] after a multivariable adjustment.Conclusions The risk of blood loss equal to or greater than 1,500 m L increases further when ultrasonic score greater than or equal to 10 points, the preparation for transfusion and referral mechanism should be considered. | CHEN Lian SHI Hui Feng JIANG Hai SHI Xiao Ming WANG Yuan Yuan ZHANG Ai Qing CHONG Yi Wen ZHAO Yang Yu | 2021 | Biomedical and Environmental Sciences2021，34，2： | 9 |
| 18 | Relationship between Maternal PBMC HBV cccDNA and HBV Serological Markers and its Effect on HBV Intrauterine Transmission显示文摘Objective To investigate the relationship between maternal peripheral blood mononuclear cells (PBMC) hepatitis B virus(HBV) covalenty closed circular deoxyribonucleic acid(cccDNA) and other HBV serological markers and its effects on HBV intrauterine transmission. Methods We enrolled 290 newborns and their hepatitis B surface antigen(HBsAg) positive mothers. HBV cccDNA in PBMC and HBV DNA in serum were detected by a real‐time PCR‐TaqM an probe while HBV serological markers were detected with an electrochemiluminescence immunoassay. Results There was a positive correlation between the levels of PBMC HBV cccD NA and serum HBV DNA and HBeA g(r = 0.436 and 0.403, P < 0.001). The detection rate of pattern A [‘HBsA g(+), HBeA g(+), and anti‐HBc(+)’] was significantly higher in the PBMC HBV cccD NA positive group than in the control group(χ^2 = 48.48, P < 0.001). There was a significant association between HBV intrauterine transmission and PBMC HBV cccD NA(χ^2 = 9.28, P = 0.002). In the presence of serum HBV DNA, HBeA g, and PBMC HBV cccD NA, the risk of HBV intrauterine transmission was three times higher(OR = 3.69, 95% CI: 1.30‐10.42) than that observed in their absence. The risk of HBV intrauterine transmission was the greatest(OR = 5.89, 95% CI: 2.35‐14.72) when both PBMC HBV cccD NA and pattern A were present. A Bayesian network model showed that maternal PBMC HBV cccD NA was directly related to HBV intrauterine transmission. Conclusion PBMC HBV cccDNA may be a direct risk factor for HBV intrauterine transmission. Our study suggests that serological markers could be combined with PBMC‐related markers in prenatal testing. | WANG Dan Dan YI Lin Zhu WU Li Na YANG Zhi Qing HAO Hai Yun SHI Xiao Hong WANG Bo FENG Shu Ying FENG Yong Liang WANG Su Ping | 2019 | Biomedical and Environmental Sciences2019，32，5： | 8 |
| 19 | Malnutrition and Quality of Life in Chinese Cancer Patients: a Clinical Study of 23,994 Subjects显示文摘Background Malnutrition is common in patients with cancer,and can negatively impact their quality of life(QoL)and even survival.However,there is currently no large data available on the prevalence of malnutrition in Chinese cancer patients.This study evaluated the prevalence of malnutrition and the QoL of Chinese patients with locoregional,recurrent or metastatic cancer.Methods We conducted a nationwide observational,multi-center,hospital-based cross-sectional study within the Chinese Society of Nutritional Oncology(CSNO)Network.All of the patients were diagnosed with one of the following 18 different types of malignant tumors:lung cancer,gastric cancer,liver cancer,colorectal cancer,breast cancer,esophageal cancer,cervical cancer,endometrial cancer,nasopharyngeal carcinoma,malignant lymphoma,leukemia,pancreatic cancer,ovarian cancer,prostate cancer,bladder cancer,brain cancer,biliary tract malignant tumors or gastrointestinal stromal tumors.These patients were enrolled from 72 hospitals located in different regions of China.The patients’nutritional status was evaluated based on the body mass index(BMI),loss of bodyweight,laboratory measurements and patient generated-subjective global assessment(PG-SGA)scores.The cancer patients’physical status and QoL were assessed by the Karnofsky Performance Status(KPS)questionnaire and the European Organization for Research and Treatment of Cancer(EORTC)QLQ-C30 questionnaire,respectively.Results From December 2013 to April 2016,23,994 patients hospitalized for cancer treatment(such as surgery,chemotherapy or radiotherapy)were enrolled in the study.The patients included 12,494(52.9%)males and 11,124(47.1%)females.The mean age was 55.8±13.7 years.The proportions of patients in cancer stagesⅠ,Ⅱ,Ⅲ,Ⅳand uncertain were 11.5%,20.3%,27.5%,30.2%and 10.5%,respectively.Among the 23,994 inpatients,the proportions of patients who were underweight(BMI<18.5 kg/m2),normal(18.5 kg/m2 | Hong Xia Xu Chun Hua Song Zhen Ming Fu Chang Wang Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Fu Xiang Zhou Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Min Weng Qing Hua Yao Jiu Wei Cui Wei Li Han Ping Shi the Investigation on Nutrition Status and Clinical Outcome of Common Cancers(INSCOC)Group | 2021 | Journal of Nutritional Oncology2021，6，1： | 8 |
