OBJECTIVETo evaluate the safety and efficacy between endoscopic papillary balloon dilatation (EPBD) and endoscopic sphincteropapillotomy ( EST) for common bile duct stones using meta-analysis method.

METHODSRandomizd controlled trials comparing EPBD with EST for common bile duct stones and published from January 1990 to July 2012 were recruited. This meta-analysis was conducted to estimate short-term and long-term complications. Fixed random effect model or random effect model was established to analyze the data.

RESULTSTwelve randomizd controlled trials were included in this analysis. These studies included 1865 patients, 925 of them were treated with EPBD and 940 were treated with EST. The analysis of basic characteristics of these included studies showed that: compared to EST, patients in the EPBD group were younger (OR = -1.16, 95% CI: -1.49 to -0.84, P = 0.00), while in two groups, there were no significant difference (P > 0.05) in gender proportion, average size of stones, number of gallstones, previous cholecystectomy, the number of merged duodenal diverticulum, common bile duct diameter, the total follow-up time. Also, compared to EST, the overall stone clearance in the EPBD group was lower (OR = 0.64, 95% CI: 0.42 to 0.96, P = 0.03), pancreatitis incidence was higher (OR = 2.67, 95% CI: 1.61 to 4.43, P = 0.00), incidence of bleeding (OR = 0.12, 95% CI: 0.04 to 0.34, P = 0.00), acute cholecystitis (OR= 0.39, 95% CI: 0.18 to 0.84, P = 0.02), total long-term complication rate (OR = 0.53, 95% CI: 0.36 to 0.77, P = 0.01), stone recurrence rate more than a year were lower (OR= 0.48, 95% CI: 0.26 to 0.90, P = 0.02). While in two groups, there were no significant difference (P > 0.05) in the stone removal on 1 '' attempt, the total near-term complications and acute cholangitis.

CONCLUSIONSOn the basis of lower rates of bleeding, EPBD seems to be preferred strategy over EST for endoscopic remove of common bile duct stones in patients who have coagulopathy. Although stone recurrence rate more than a year of EPBD is lower, but the overall stone clearance rate is lower and the risk of pancreatitis is higher than that of EST.

OBJECTIVETo study the transmission route and epidemiological features of Clonorchis sinensis infection in Shenzhen area--the biggest immigration city of Southern China.

METHODSIn this study, we examined 1473 individuals (710 males and 763 females) to determine the current status of C. sinensis infection among the people in one village in Zhujiang river region, Guangdong province, China. Blood samples were detected on antibody of C. sinensis with enzyme linked immunosorbent assay,and stool specimens from sera positive cases were examined by modified Kato-Katz thick smear to confirm the density of infection. People were interviewed on their life styles under the structured questionnaire which was administered by trained staff members. Major content of the questionnaire included eating raw fish, using the same utensils for both raw fish and cooked food, using feces of domestic animals and human feces to feed fish and so on.

RESULTSAmong 1473 people examined, 70 (4.75%) were found infected with C. sinensis. By counting eggs per gram feces (EPG), it was found that heavy intensities of infection in males was stronger than that of females,and the overall average EPG was 41.87. Of 1473 interviewees, 54% of them did not know about fluke disease or its transmission route, 12% of those who knew about the fluke but believed that the infection caused no harm or only slight harm to their health. 27% of the interviewees ate raw fish at least 1-2 times per months with 5% of the families using the same utensils for both raw fish and cooked food. 40% of the fish ponds owners fed their fish with the feces of domestic animals and human feces.

CONCLUSIONTogether with these results, unhealthy behaviors, poor knowledge, inappropriate farming/fishery practices, eating raw fish were important factors influencing the C. sinensis prevalence in humans.

OBJECTIVE: To investigate the changes of collagen fibers and the expression of osteopontin in the left ventricle in cases of hypertrophic cardiomyopathy (HCM), along with the significance of their potential forensic application. METHODS: Fifteen cases of HCM, 15 cases of coronary heart disease with cardiac hypertrophy and 20 cases of traffic accidents were selected as HCM group, coronary heart disease group and control group, respectively. Collagen volume fraction and osteopontin expression were observed and compared by HE staining, Masson trichrome staining and immunohistochemistry methods. Imaging and statistical methods were used for quantitative analysis. RESULTS: Collagen volume fraction in left ventricle of HCM and coronary heart disease were significantly higher than that in the control group (P < 0.05), which was not significantly different between the HCM group and the coronary heart disease group. The integral light density value of osteopontin in left ventricular cardiomyocytes of the HCM group and the coronary heart disease group were significantly higher than that of the control group (P< 0.05), and the value of the HCM group was also significantly higher than that of coronary heart disease group (P < 0.05). CONCLUSION The increased contents of collagen fibers and the overexpression of osteopontin may play an important role in myocardial fibrosis, and they can be used as markers in aid of diagnosing sudden death due to HCM.

Objective To delimit the natural infectious focus, including the distribution of wildlife,species, ecology of intermediate hosts and final host of Angiostrongylus cantonensis, as well as the routes of transmission and epidemiological characteristics and wildlife of human Angiostrongylus cantonensis, based on human diverging cases identified in Shenzhen, southern area of China. Methods Data including rate of infection and density of Angiostrongylus cantonensis among different hosts in 12 different areas in Shenzhen was collected, using microscope to inspect homogenate liquids of snails. Wild mice were captured with mouse cage to examine the adult Angiostrongylus cantonensis. Using larva isolated from wild-snails-infected rats to observe the life cycle of Angiostrongylus cantonensis. Results Wild life of Angiostrongylus cantonensis existed in the southwest part of Shenzhen with its majority intermediate hosts as Achatina fulica. The overall rate of infection was 31% in wildlife and final host was found to be Rattus andersoni, Achatina fulica which were extensively distributed in the shrub region of Shenzhen because of suitable climate,humidity and vegetation for generating the life cycle of Achatina fulica. Human infected Angiostrongylus cantonensis was mainly due to eating raw snails or vegetables contaminated by larva of Angiostrongylus cantonensis.The peak of infection was seen from April to November in Shenzhen area.Conclusion Wildlife of Angiostrongylus cantonensis existed in the southwest part of Shenzhen with major wildlife reservoir including fresh water snail and wild mouse. The existence of natural focus Angiostrongylus cantonensis was now recognized as an important source of human angiostrongliasis in Shenzhen area.

OBJECTIVEAn accurate clinical TNM staging of lung cancer is essential for the precise determination of the extent of the disease in order that an optimal therapeutic strategy can be planned. This is especially true in patients with marginally resectable tumors. Clinical over-staging of the disease may deny a patient the benefit of surgery, whereas under-staging may oblige a patient to accept a fruitless or even harmful surgery. We aimed to analyze preoperative clinical (c-TNM) and postoperative surgico-pathologic staging (p-TNM) of lung cancer patients in order to evaluate the accuracy of our clinical staging and its implications on the surgical strategy for lung cancer.

METHODSWe did a retrospective comparison of c-TNM and p-TNM staging of 2007 patients with lung cancer surgically treated from January 1999 to May 2003. Preoperative evaluation and c-TNM staging of all patients were based on physical examination, laboratory studies, routine chest X-ray and CT scan of the chest and upper abdomen. Other examinations included sputum cytology, bronchoscopy, abdominal ultrasonography, bone scintiscan, brain CT/MRI, and mediastinoscopy whenever indicated.

RESULTSIn the present study the comparison of c-TNM and p-TNM staging of 2007 patients with lung cancer revealed an overall concurrence rate of only 39.0%. In the entire series the extent of disease was clinically underestimated in 45.2% and overestimated in 15.8% of the patients. Among all c-TNM stages the c-IA/B stage of 1105 patients gave the highest rate (55.2%) of underestimating the extent of disease. Clinical staging of T subsets was relatively easy with an overall accuracy rate of 72.9%, while that of N subsets was relatively more difficult with an overall accuracy rate of 53.5%. Analysis also showed that c-IV stage may not be an absolute contraindication to surgery, because in half of the patients, c-M1 turned out to be p-M0, providing the possibility of resectional surgery depending on the status of T and N.

CONCLUSIONFor reasons to be further determined, the present preoperative clinical TNM staging of lung cancer remains a crude evaluation. Further efforts to improve its accuracy are needed.

Objective: During laparoscopic pelvic operational procedure for obese patients with rectal cancer, the large amount of fat in the abdominal cavity often impairs the exposure of the surgical field, resulting in technical difficulty. In contrast, robotic surgery has the advantages of being more minimally invasive, precise, and flexible. This study compared the clinical efficacy of robotic and laparoscopic radical resection of rectal cancer for overweight and obese patients. Methods: A retrospective cohort study was conducted. Clinical data of 173 patients with rectal cancer and a body mass index (BMI) ≥ 25 kg/m(2) who received robotic or laparoscopic radical rectal resection at the First Affiliated Hospital of Nanchang University from January 2015 to February 2019 were retrospectively collected. Of 173 patients, 90 underwent robotic surgery and 83 underwent laparoscopic surgery. The intraoperative parameters, postoperative short-term and follow-up status were analyzed and compared between the two groups. The follow-up ended in December 2019. Results: Of 173 patients, 103 were male and 70 were female with a median age of 62 (range 29 to 86) years. The average BMI was (27.2±1.6) kg/m(2) in the robotic group and (27.3±1.5) kg/m(2) in the laparoscopic group. No significant differences in baseline data were observed between two groups (all P>0.05). As compared to the laparoscopic group, the robotic group had less intraoperative blood loss [(73.0±46.8) ml vs. (120.9±59.9) ml, t=-5.881, P<0.001] and higher postoperative hospitalization expense [(61±15) thousand yuan vs (52±13) thousand yuan, t=3.468, P=0.026]. The conversion rate in the robotic group was 1.1% (1/90), which was lower than 6.0% (5/83) in the laparoscopic group, but the difference was not statistically significant (P=0.106). There were no statistically significant differences between the two groups in operative time, number of intraoperative blood transfusion, number of harvested lymph nodes, time to the first flatus, postoperative hospital stay and morbidity of total postoperative complications (all P>0.05). Five (6.0%) patients in the laparoscopic group developed urinary dysfunction, while no case in the robotic group developed postoperative urinary dysfunction (P=0.024). The 173 patients were followed up for 8-59 months, with a median follow-up of 36 months. The 3-year overall survival rate of robotic group and laparoscopic group was 89.8% and 86.6%, respectively without significant difference between the two groups (P=0.638). The 3-year disease-free survival rate of the robotic group and the laparoscopic group was 85.6% and 81.5%, respectively without significant difference as well (P=0.638). Conclusions: Robotic radical surgery is safe and feasible for overweight and obese patients with rectal cancer. Compared with laparoscopic radical surgery, it has advantages of clear vision of surgical exposure, less intraoperative blood loss, less pelvic autonomic nerve damage, and operation in a narrow space.

Objective:To explore the material basis and mechanism of Sangjiang Ganmao injection （SG） in the treatment of common cold by ultra-performance liquid chromatography-quadrupole/electrostatic field orbitrap high resolution mass spectrometry （UPLC-Q-Orbitrap HRMS） and network pharmacology. Method:UPLC-Q-Orbitrap HRMS was used to identify the chemical components of SG with mobile phase of acetonitrile （A）-0.1% formic acid aqueous solution （B） for gradient elution （0-10 min， 4%-15%A； 10-35 min， 15%-30%A； 35-45 min， 30%-33%A； 45-55 min， 33%-60%A； 55-58 min， 60%A）， flow rate of 0.2 mL·min^-1， electrospray ionization （ESI） and scanning range of m/z 100-1 500 under positive and negative ion modes. Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and GeneCards 5.0 database were used to screen and predict the potential targets of chemical components in SG， STRING 11.0 database and Cytoscape 3.7.2 software were used to construct protein-protein interaction （PPI） network model， gene ontology （GO） analysis and pathway analysis were performed on potential targets by Metascape 3.5， Reactome database and Kyoto Encyclopedia of Genes and Genomes （KEGG）， Cytoscape 3.7.2 software was used to build the network of "herbs-ingredients-key targets". Result:A total of 54 components in SG were identified， and 80 potential targets of SG for treatment of common cold were predicted and screened based on this. SG exerted therapeutic effects by acting on targets such as interleukin （IL）-6， tumor necrosis factor （TNF） and IL-10， and signaling pathways such as IL-17 signaling pathway， TNF signaling pathway and interaction of cytokine receptors. Conclusion:SG may interfere with the expression of inflammatory cytokines by acting on related targets and pathways such as inflammation and immune system， and regulate the immune function of the body as a whole， thereby exerting a therapeutic effect.

OBJECTIVETo compare the short-term outcomes of surgical treatment for non-small cell lung cancer (NSCLC) by video-assisted thoracoscopic surgery (VATS) and open thoracotomy (OT).

METHODSData of 737 consecutive NSCLC patients who underwent surgical treatment for non-small cell lung cancer by video-assisted thoracoscopic surgery and 630 patients who underwent pulmonary resection via open thoracotomy (as controls) in Cancer Institute & Hospital, Chinese Academy of Medical Sciences between January 2009 and August 2011 were retrospectively reviewed. The risk factors after lobectomy were also analyzed.

RESULTSIn the 506 NSCLC patients who received VATS lobectomy, postoperative complications occurred in 13 patients (2.6%) and one patient died of acute respiratory distress syndrome (0.2%). In the 521 patients who received open thoracotomy (OT) lobectomy, postoperative complications occurred in 21 patients (4.0%) and one patient died of pulmonary infection (0.2%). There was no significant difference in the morbidity rate (P > 0.05) and mortality rate (P > 0.05) between the VATS group and OT group. In the 190 patients who received VATS wedge resections, postoperative complications occurred in 3 patients (1.6%). One hundred and nine patients received OT wedge resections. Postoperative complications occurred in 4 patients (3.7%). There were no significant differences for morbidity rate (P = 0.262) between these two groups, and there was no perioperative death in these two groups. Univariate and multivariate analyses demonstrated that age (OR = 1.047, 95%CI: 1.004 - 1.091), history of smoking (OR = 6.374, 95%CI: 2.588 - 15.695) and operation time (OR = 1.418, 95%CI: 1.075 - 1.871) were independent risk factors of postoperative complications.

CONCLUSIONSTo compare with the NSCLC patients who should undergo lobectomy or wedge resection via open thoracotomy, a similar short-term outcome can be achieved via VATS approach.
