Laparoscopic total mesorectal excision versus transanal total mesorectal excision for mid and low rectal cancer: A systematic review and meta-analysis.

Background: Laparoscopic total mesorectal excision (LaTME) and transanal total mesorectal excision (TaTME) are popular mid and low rectal cancer trends. However, there is currently no systematic comparison between LaTME and TaTME of mid and low rectal cancer. Therefore, we systematically study the perioperative and pathological outcomes of LaTME and TaTME in mid and low rectal cancer.

[Emissions Inventory of Smoldering Chinese Kangs and Their Contribution to PM Pollution in Lanzhou City].

Considering regional differences in economic development, the activity level of smoldering Chinese kangs was confirmed by surveys in typical areas in Lanzhou City. An emissions inventory of smoldering Chinese kangs in Lanzhou City in 2016 was established using the emissions factor approach. The emissions amounts of SO, NO, NH, CO, volatile organic compounds (VOCs), PM, PM, organic carbon (OC) and elemental carbon (EC) were 340.

Evaluation of the Direct and Indirect Regulation Pathways of Glutathione Target to the Hepatotoxicity of Microcystin-LR.

Glutathione (GSH) plays crucial roles in regulating the hepatotoxicity of Microcystin-LR (MCLR) by inhibiting oxidative stress or by toxin conjugation. Based on MCLR conjugation product preparation and purification, the direct and indirect regulation pathways for GSH were fully evaluated. Protein phosphatase inhibition analysis verified that GSH conjugation was an effective pathway to regulate the inhibition effect of MCLR, while GSH had slight influence on the toxicity of MCLR.

[Study of effects of drugs on myocardial hypertrophy due to overload].

Objective: To study the relation of expression change of tumor necrosis factor-alpha (TNF-alpha), angiotensin II (Ang II), and endothelin-1 (ET-1), and the effect of imidapril on myocardial hypertrophy due to overload.

Methods: Sixty-three rats were randomly divided into four groups: sham operation (n=15), overload group (n=16), imidapril group (n=16), and Caweidiluo group (n=16). Hypertrophic myocardium was reproduced in rats by constricting abdominal aorta.
