Combined effects of cadmium and simulated acid rain on soil microbial communities in the early cultivation of Populus beijingensis seedlings.

The combined cadmium (Cd) and acid rain pollution poses a significant threat to the global ecological environment. Previous studies on the combined adverse effects have predominantly focused on the aboveground plant physiological responses, with limited reports on the microbial response in the rhizosphere soil. This study employed Populus beijingensis seedlings and potting experiments to simulate the impacts of combined mild acid rain (pH=4.

Good learners or trouble makers? Study on the relationship between academic performance and antisocial behavior of junior high school students.

The school bullying incident has aroused widespread concern in current society. How to manage students' anti-social behavior has become an increasingly serious problem for administrators. This study uses a sample of 8270 junior high school students to examine the mechanism of academic achievement on students' antisocial behavior.

Laparoscopic versus open surgery in children with choledochal cysts: a meta-analysis.

Objective: To compare the safety and efficacy between laparoscopic and open cyst excision with hepaticojejunostomy for children with choledochal cysts using meta-analysis.

Methods: Studies comparing the laparoscopic and the open choledochal cyst excision that met the inclusion criteria for data extraction were identified from electronic databases (PubMed, Embase, Science Citation Index, and the Cochrane Library) up to November 2014. The proceedings of relevant congress were also searched.

[Application of pancreaticojejunostomy procedures selection strategy in pancreaticoduodenectomy and risk factors analysis of pancreatic fistula after operation].

Objective: To evaluate the pancreaticojejunostomy procedures selection strategy in pancreaticoduodenectomy and to analyze risk factors of pancreatic fistula.

Methods: Clinical data of 352 patients who received pancreaticoduodenectomy from September 2009 to September 2012 were retrospectively analyzed. For patients with soft pancreas, binding pancreaticojejunostomy was applied to 153 patients.

Potential biomarkers for sensitivity of gallbladder cancer cells to gemcitabine.

Gemcitabine (Gem)-based chemotherapies are the main therapeutic regimens for patients with unresectable advanced or metastatic gallbladder cancer (GBC). However, the modest ORR and mild benefit on survival demonstrates the need for finding biomarkers for sensitivity to Gem and hence improving the therapy. In present work, two GBC cell lines with vast difference in sensitivity to Gem were subjected to DNA microarray analysis.

Inducible costimulator (ICOS) enhances the cytolytic activity of cytokine-induced killer cells against gallbladder cancer in vitro and in vivo.

The generation of genetically modified immunological effector cells is of potential therapeutic value in the treatment of malignancies. Cytokine-induced killer cells (CIKs) have been described as highly efficient cytotoxic effector cells capable of recognizing and lysing tumor cell targets in a non-major histocompatibility complex restricted fashion. In the present study, we evaluated the effects of inducible costimulator (ICOS) on the cytotoxicity of CIK cells against gallbladder cancer.

Outcome of gallbladder preservation in surgical management of primary bile duct stones.

Aim: To evaluate the methods and outcome of gallbladder preservation in surgical treatment of primary bile duct stones.

Methods: Thirty-five patients with primary bile duct stones and intact gallbladders received stone extraction by two operative approaches, 23 done through the intrahepatic duct stump (RBD-IDS, the RBD-IDS group) after partial hepatectomy and 12 through the hepatic parenchyma by retrograde puncture (RBD-RP, the RBD-RP group). The gallbladders were preserved and the common bile duct (CBD) incisions were primarily closed.
