[Network Meta-analysis of different Chinese medicine injections combined with conventional western medicine in treatment of acute heart failure].

This study aims to evaluate the efficacy and safety of Chinese medicine injection in the treatment of acute heart failure. PubMed, Cochrane Library, EMbase, Web of Science, CNKI, VIP, Wanfang, and SinoMed were searched for the randomized controlled trial(RCT) of Chinese medicine injection combined with conventional western medicines in the treatment of acute heart failure with the time interval from the inception to July 10, 2023. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias in the included studies.

Predictive factors for lymph node metastasis and defining a subgroup treatable for laparoscopic lymph node dissection after endoscopic submucosal dissection in poorly differentiated early gastric cancer.

Aim: To investigate the predictive factors of lymph node metastasis (LNM) in poorly differentiated early gastric cancer (EGC); to guide the individual application of a combination of endoscopic submucosal dissection (ESD) and laparoscopic lymph node dissection (LLND) in a suitable subgroup of patients with poorly differentiated EGC.

Methods: We retrospectively analyzed 138 patients with poorly differentiated EGC who underwent gastrectomy with lymphadenectomy between January 1990 and December 2015. The association between the clinicopathological factors and the presence of LNM was retrospectively analyzed by univariate and multivariate logistic regression analyses.

[Wetland landscape pattern change based on GIS and RS: a review].

Wetland is an ecological landscape with most biodiversity in nature, which has unique ecological structure and function, and contains abundant natural resources to provide material guarantee for human's living and development. Wetland landscape pattern is the comprehensive result of various ecological processes, and has become a hot issue in wetland ecological study. At present, the combination of geographic information system (GIS) and remote sensing (RS) technologies is an important way to study the wetland landscape pattern change.
