ObjectiveTo investigate the technical success rate and outcome of transjugular intrahepatic portosystemic shunt (TIPS) in preventing esophageal variceal rebleeding in patients with portal vein thrombosis (PVT) after splenectomy. MethodsA retrospective analysis was performed for the clinical data of 46 patients with PVT after splenectomy who were admitted to Shandong Provincial Hospital from December 2009 to January 2017 and underwent TIPS to prevent esophageal variceal rebleeding. According to the success or failure of TIPS, the patients were divided into TIPS success group with 38 patients and TIPS failure group with 8 patients. The two groups were compared in terms of postoperative variceal rebleeding, stent dysfunction, hepatic encephalopathy (HE), and survival. The paired t-test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier curve was used to analyze variceal rebleeding-free rate, stent patency rate, HE-free rate, and survival rate, and the log-rank test was used for comparison of cumulative rebleeding-free rate and cumulative survival rate. ResultsThe technical success rate of TIPS was 82.6%. There were significant differences in 6-, 12-, and 24-month cumulative rebleeding-free rates between the TIPS success group and the TIPS failure group (94.3%/89.8%/89.8% vs 85.7%/85.7%/28.6%, χ2=4.563, P=0.033). In the TIPS success group, the 6-, 12-, and 24-month cumulative stent patency rates were 79.3%, 74.3%, and 69.0%, respectively, and the 6-, 12-, and 24-month cumulative HE-free rates after TIPS were 72.1%, 55.5%, and 55.5%, respectively. There were significant differences in 6-, 12-, and 24-month cumulative survival rates between the TIPS success group and the TIPS failure group (94.0%/94.0%/86.2% vs 714%/71.4%/71.4%, χ2=4.988, P=0.026). ConclusionTIPS is a safe and feasible method for preventing esophageal variceal rebleeding in patients with PVT after splenectomy, and TIPS combined with a percutaneous transhepatic approach may promote technical success.

OBJECTIVETo investigate the predictive value of hepatic venous pressure gradient (HVPG) for early bleeding after esophageal variceal ligation (EVL) by analyzing the differences in HVPG in patients with and without post-EVL bleeding.
METHODSThe medical records of patients who had been diagnosed with cirrhosis and esophageal varices and who had pre-EVL HVPG measurement data were surveyed. The study population included 105 patients from October 2010 to March 2014. Data of HVPG value, previous treatment history, endoscopic manifestation, and whether bleeding and serious complications occurred within 2 weeks after the ligation procedure were investigated as independent risk factors.
STATISTICAL METHODSincluded the chi-square test and Wilcoxon test, logistic regression modeling and receiver operating characteristic (ROC) analysis using the SPSS software version 16.
RESULTSOnly HVPG value was identified as an independent risk factor of early bleeding after EVL.According to the ROC analysis, the area under the curve (AUC) of HVPG for early bleeding after EVL was 0.866; when HVPG was more than or equal to 16 mmHg, AUC was 0.838. The sensitivity was 90.9% and the specificity was 76.4%.
CONCLUSIONHVPG is an independent factor of early bleeding after EVL and when HVPG cut-off value of more than or equal to 16 mmHg is used the predictive ability has certain accuracy and high sensitivity and specificity.

Objective:
To investigate the effect of maternal passive smoking during pregnancy and girls’ overweight /obesity on the age at menarche(AAM), and to provide a reference for improving healthy development of children and adolescents.
Methods:
Based on the school entrance physical examination in 2016, a cross-section study was conducted by convenient sampling method, in a total of 2 722 students of 7th grade, from 26 middle schools in urban areas of Guangzhou. Multivariate logistic regression model was used to investigate the relationship between maternal passive smoking during pregnancy and girls’ overweight /obesity and AAM. A four-way decomposition method was used to explore the mediated effect of girls’ overweight/obesity on the relationship between maternal passive smoking during pregnancy and AAM.
Results:
The proportion of girls who had menstruate was 90.82%(2 472/2 722). The median AAM was 12.00 years old, with an early menarche rate of 34.91%(863/2 472). Compared with girls whose mother hadn’t passive smoking during pregnancy, the risk of early AAM in girls with mother passive smoking during pregnancy≤3 days/week increased by 32%(OR=1.32, 95%CI=1.06-1.65), the risk in girls with maternal passive smoking during pregnancy>3 days/week increased by 58%(OR=1.58, 95%CI=1.21-2.07). Multivariate Logistic regression analysis showed that, overweight or obesity girls had a 77% higher risk of early AAM than non-overweight/obesity girls(OR=1.77, 95%CI=1.36-2.31). The four-way decomposition analysis showed 79.60% of early AAM risk could be accounted by maternal passive smoking during pregnancy(P<0.01).
Conclusion
Girls’ overweight/obesity and maternal passive smoking during pregnancy were associated with early menarche. The effect on daughters’ age at menarche is mainly in a direct effect manner of maternal passive smoking during pregnancy.
9.Influence of birthweight and delivery mode on obesity among primary school students in Guangzhou
Chinese Journal of School Health 2021;42(2):277-281
Objective:
To explore the influence of birthweight and delivery mode on overweight/obesity and abdominal obesity in primary school students, and to provide evidence for childhood obesity prevention.
Methods:
After physical examination, questionnaire survey was conducted among 3 361 students and their parents from 3 primary schools in Guangzhou selected through stratified clustering sampling. Information about birthweight and delivery mode was collected. Logistic regression model was used to analyze the association of birthweight and delivery mode with overweight/obesity and abdominal obesity. The multiplicative interaction term and the Delta method was used to explore the potential interaction.
Results:
The prevalence rate of overweight and obesity for primary school students was 21.33%, and the rate of abdominal obesity was 12.08%. Multivariate Logistic regression analysis showed that delivery by cesarean section was associated with 44% increased risk of overweight/obesity(OR=1.44, 95%CI=1.16-1.80), as compared to vaginal delivery. Higher birthweight was linked to increased risk of overweight/obesity(OR=1.62, 95%CI=1.09-2.42). There was no significant association of birth weight and delivery mode with abdominal obesity in multivariate analysis(P>0.05). Additionally, a positive additive interaction was seen between delivery mode and parental obesity for students risk of overweight/obesity(RERI=0.33, 95%CI=0.02-0.65), as well as for the risk of abdominal obesity(RERI=0.39, 95%CI=0.12-0.65).
Conclusion
Cesarean section delivery and higher birthweight are linked to increased risk of overweight and obesity in primary school students. The synergistic effect of cesarean section and parental obesity may increase the risk of childhood obesity.

BACKGROUND AND OBJECTIVEHow to prolong progression free survival (PFS) and overall survival (OS) of patients with small cell lung cancer (SCLC) has been one of the hottest issues. We retrospectively reviewed our data to compare the survival of immediate with delayed topotecan after first-line therapy in SCLC.
METHODSIn our retrospective study, 53 patients with SCLC were divided into two groups as follow: patients receiving topotecan-containing regimen as maintenance/consolidation (maintenance/consolidation chemotherapy group) and salvage chemotherapy (salvage chemotherapy group). The Log-rank test was used to assess the difference in OS between two groups. Cox regression model was used for the multivariable analysis of independent prognostic factors.
RESULTSTwenty-nine patients received topotecan as maintenance/consolidation treatment, whereas 24 patients salvage chemotherapy. The response rates were 51.7% and 41.7%, respectively. The median survival time were 20 months and 27 months respectively (P = 0.89). Multivariate Cox regression analyses identified sex and stage as independent prognostic factors.
CONCLUSIONEfficacy of first-line therapy was improved by topotecan maintenance/ consolidation treatment, which did not result in any significant survival benefits in SCLC.
