Clinical efficacy of laparoscopic cholecystectomy combined with endoscopic papillary balloon dilation in treatment of gallbladder stones with common bile duct stones: A retrospective study.

Background: The incidence of cholelithiasis has been on the rise in recent years, but the choice of procedure is controversial.

Aim: To investigate the efficacy of laparoscopic cholecystectomy (LC) combined with endoscopic papillary balloon dilation (EPBD) in patients with gallbladder stones (GS) with common bile duct stones (CBDS).

Methods: The clinical data of 102 patients with GS combined with CBDS were selected for retrospective analysis and divided into either an LC + EPBD group ( = 50) or an LC + endoscopic sphincterotomy (EST) group ( = 52) according to surgical methods.

Efficacy and safety of endoscopic submucosal dissection for early gastric cancer and precancerous lesions in elderly patients.

Background: With advancements in the development of endoscopic technologies, the endoscopic submucosal dissection (ESD) has been one of the gold-standard therapies for early gastric cancer.

Aim: To investigate the efficacy and safety ESD in the treatment of early gastric cancer and precancerous lesions in the elderly patients.

Methods: Seventy-eight elderly patients with early gastric cancer and precancerous lesions admitted to the Third Affiliated Hospital of Qiqihar Medical University were selected and classified into two groups according to the different surgical therapies they received between January 2021 and June 2022.

[Secondary productivity of macrobenthos in rocky intertidal zone of Yushan Islands, Zhejiang Province].

In order to understand the current status of macrobenthos in intertidal zone of Yushan Islands, macrobenthos samples were collected from 5 sections in the intertidal zone in four seasons from March 2009 to January 2010, with the density, biomass, secondary productivity, and P/B value of the macrobenthos investigated by using Brey's empirical formula. The mean density of the marobenthos was 1419.5 ind x m(-2), mean biomass in ash free dry mass (AFDM) was 565.

[An association study of abdominal obesity and polymorphisms of UCP2 and SREBP1c genes].

Objective: To investigate the association of -866A/G polymorphism of uncoupling protein 2 (UCP2) gene, and 54G/C polymorphism of sterol regulatory element binding protein 1c (SREBP1c) gene with abdominal obesity in the population of type 2 diabetes mellitus families.

Methods: Eligible type 2 diabetes mellitus cases from newly diagnosed and previous hospitalized patients were choson, then their family members (siblings and parents) tracked. A set of questionnaires was administered to obtain information on demographic characteristics.
