Objective To evaluate the efficacy and safety of endoscopic versus open component separation technique (CST) for abdominal hernia.Methods Systematic review was carried out to identify the controlled clinical studies comparing endoscopic CST with open CST for abdominal hernia.The Meta-analysis was performed with RevMan 5.2 software.Results The selection criteria was met in five studies.A total of 185 patients with abdominal hernia were included.Analysis of the data suggested that there was no significant differences in recurrence rate between endoscopic CST and open CST(P =0.84,risk difference =-0.01,95％ CI-0.12 to 0.10).However,endoscopic CST compared with open CST was associated with a significant reduction of postoperative wound complications (P ＜ 0.000 1,odds ratio =0.19,95％ CI 0.09 to 0.41).And there was no significant differences in operation time,intraoperative blood loss and postoperative hospital stay (all P ＞ 0.05).Conclusions As compared to open CST,endoscopic CST show equivalent clinical effects with similar recurrence rate.However,endoscopic CST was associated with a significant reduction of postoperative wound complications,and there was no significant differences in in operation time,intraoperative blood loss and postoperative hospital stay.

Objective To explore the application value of the extra-glissonian pedicle transection approach guided by arantius' ligament in laparoscopic left hemihepatectomy.Methods The retrospective cohort study was conducted.The clinical data of 57 patients who underwent laparoscopic left hemihepatectomy in the First Affiliated Hospital of Fujian Medical University from January 2015 to January 2018 were collected.There were 18 males and 39 females,aged from 29 to 75 years,with an average age of 57 years.Of the 57 patients,22 undergoing the laparoscopic left hemihepatectomy with extra-glissonian pedicle transection approach guided by arantius' ligament and 35 undergoing laparoscopic left hemihepatectomy with regular intra-glissonian pedicle transection approach were allocated into the extra-glissonian transection group and intra-glissonian transection group,respectively.Observation indicators:(1) intraoperative situations and postoperative short-term outcomes;(2) postoperative complications;(3) follow-up.Patients were followed up by outpatient examination and telephone interview to investigate postoperative recurrence of diseases up to June 2018.Measurement data with normal distribution were represented as Mean±SD and comparison between groups was analyzed using the t test.Count data were described as absolute number or percentage and comparison between groups was analyzed using the chi-square test.Results (1) Intraoperative situations and postoperative short-term outcomes:the operation time,dissection time of left hepatic pedicle,volume of intraoperative blood loss were (123± 37) minutes,(14± 5) minutes,(337± 169) mL in the extra-glissonian transection group and (148± 27) minutes,(22± 3) minutes,(495±203) mL in the intra-glissonian transection group,respectively,showing statistically significant differences between the two groups (t =2.992,7.733,3.045,P＜0.05).Cases with intraoperative blood transfusion,time of gastrointestinal recovery,time for postoperative drainage-tube removal,duration of postoperative hospital stay were 1,(1.8±0.9)days,(3.2±0.9)days,(8.2± 1.7)days in the extra-glissonian transection group and 4,(2.0± 0.8)days,(3.6±0.8)days,(10.0±4.0)days in the intra-glissonian transection group,respectively,showing no statistically significant difference between the two groups (x2 =0.171,t=1.304,1.857,1.622,P＞0.05).There was no uncontrolled hemorrhage or air embolism in the two groups.(2) Postoperative complications:3 patients had complications of Clavien-Dindo classification Ⅰ in the extra-glissonian transection group including 1 of pulmonary infection,1 of abdominal infection,1 of incisional infection and 7 had complications in the intraglissonian transection group including 2 of pulmonary infection,2 of liver sectional effusion,1 of subphrenic abscess,1 of biliary leakage,1 of incisional infection,showing no statistically significant difference between the two groups (x2=0.066,P＞0.05).Patients with postoperative complications were cured and discharged after symptomatic treatment.There was no perioperative death in the two groups.(3) Follow-up:57 patients were followed up for 5-41 months,with a median time of 23 months.Two and 1 patients had tumor recurrence and hepatolithiasis recurrence in the intra-glissonian transection group,without recurrence of hepatic hemangioma or cholangiocarcinoma.Five patients had tumor recurrence in the intra-glissonian transection group,without recurrence of hepatic hemangioma,hepatolithiasis or cholangiocarcinoma.The disease recurrence rate was 13.6％ (3/22) and 14.3％(5/35) in the extra-glissonian transection group and intra-glissonian transection group,respectively,showing no statistically significant difference between the two groups (x2 =0.104,P＞0.05).Conclusions Extraglissonian pedicle transection approach guided by arantius' ligament in laparoscopic left hemihepatectomy is feasible and effective,which can control hepatic blood inflow of left liver,simplify the surgery procedure and shorten dissection time of left pedicle,in order to save operation time and reduce volume of intraoperative blood loss.

Objective:To understand the commercial homosexual behavior characteristics of men who have sex with men (MSM) and the factors associated with unprotected anal intercourse (UAI) in this population, and provide reference for the development of intervention strategy in MSM.Methods:Men who were aged ≥16 years and had anal sex with men in the past 6 months were recruited through internet in Fuzhou from January to December 2023 for a cross-sectional study with a sample size of 283. Multivariate logistic regression model was used to analyze the factors associated with the incidence of UAI in the past 6 months in MSM. The SPSS 25.0 software was used for statistical analysis.Results:In 4 484 MSM, the proportion of those with commercial homosexual behaviors was 9.59% (430/4 484), the average age was (27.00±9.07) years. In the MSM with commercial homosexual behaviors, 70.00% (301/430) had anal sex in the past one week, and 43.02% (185/430) had anal sex with more than 10 partners in the past 6 months. The proportion of MSM with UAI was 75.58% (325/430) in the past 6 months. The results of multivariate analysis showed showed that in MSM with commercial homosexual behaviors in the past 6 months, compared with those who were students, age >18 years at the first sexual intercourse, had not anal sex in the past one week, and anal sex with less than 10 partners in the past 6 months, the risk for UAI was higher in those who were not students (a OR=1.99,95% CI:1.18-3.36), those who were aged ≤18 years at first sexual intercourse sex (a OR=2.04,95% CI:1.26-3.29), those who had anal sex in the past one week (a OR=2.04,95% CI:1.25-3.33), and those who had anal sex with more than 10 partners in the past 6 months (a OR=1.97,95% CI:1.16-3.35). Conclusions:The risk for UAI was high in MSM with commercial homosexual behaviors in Fuzhou, so it is necessary to improve the awareness of safe sex and promote sex with regular partners and condom use, and preventing drug abuse in MSM.

Objective:To analyze the changes in cardiac structure and function in women with different types of hypertensive disorders in pregnancy (HDP) and explore their influencing factors.Methods:A total of 1 967 pregnant women diagnosed with HDP who delivered at Peking University Third Hospital from January 1, 2014 to April 15, 2022 were included in the study. They were categorized into four groups based on specific HDP diagnoses: gestational hypertension (506 cases, 25.7%), pre-eclampsia (589 cases, 29.9%), pregnancy complicated with chronic hypertension (332 cases, 16.9%) and chronic hypertension with pre-eclampsia (540 cases, 27.5%). Differences in cardiac structure and function among four groups were retrospectively analyzed. Cardiac structure indicators included left atrial diameter (LAD), left atrial area (LAA), right atrial area (RAA), left ventricular end-diastolic diameter (LVEDD), interventricular septal thickness (IVST), left ventricular posterior wall thickness (LVPWT), systolic function indicators included left ventricular ejection fraction (LVEF), lateral systolic mitral annular velocity (Sm), diastolic function indicators included peak early diastolic mitral in flow velocity (E)/peak late diastolic mitral in flow velocity (A), and E/peak early diastolic myocardial velocity of the lateral mitral annulus early diastolic velocity (Em). Influencing factors on cardiac structure and function were analyzed using generalized linear regression. Influencing factors were assessed by generalized linear regression.Results:(1) General clinical data: the differences in age, gestational week at delivery, blood pressure, proportion of diabetes, and length of hospital stay were statistically significant among four different HDP types (all P<0.05). (2) Compared with pregnant women with pregnancy complicated with chronic hypertension, pre-eclampsia, and gestational hypertension, those with chronic hypertension with pre-eclampsia had larger LAD, LAA, RAA and LVEDD (all P<0.001), thicker IVST and LVPWT (all P<0.001), and reduced left ventricular diastolic function (E/A, lateral Em, E/Em) and systolic function (lateral Sm; all P<0.001). Pregnant women with gestational hypertension had the least changes in cardiac structure and function. Compared with pregnant women with pre-eclampsia, those with pregnancy complicated with chronic hypertension had smaller RAA ( P<0.001) and lower E/A ( P<0.001), with no significant difference in other indicators (all P>0.05). (3) Chronic hypertension with pre-eclampsia, pregnancy complicated with chronic hypertension, and pre-eclampsia were associated with larger LAD, LAA, and LVEDD, and lower lateral Em (all P<0.05). Conclusions:Different types of HDP are associated with distinct changes in cardiac structure and function. Chronic hypertension with pre-eclampsia demonstrates the most pronounced alterations, followed by pre-eclampsia and pregnancy complicated with chronic hypertension, and gestational hypertension showed the least changes.
