[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. Stata 15.1 was used to perform network Meta-analysis. A total of 117 RCTs were included, involving 10 529 patients and 7 Chinese medicine injections: Shenfu Injection, Shenmai Injection, Danhong Injection, Puera-rin Injection, Xinmailong Injection, Shengmai Injection, and Yiqi Fumai Injection. Network Meta-analysis yielded the following results.(1) In terms of improving the total response rate, the surface under the cumulative ranking curve(SUCRA) ranking was Shengmai Injection + conventional western medicine > Danhong Injection + conventional western medicine > Shenmai Injection + conventio-nal western medicine > Shenfu Injection + conventional western medicine > Xinmailong Injection + conventional western medicine > Yiqi Fumai Injection + conventional western medicine > Puerarin Injection + conventional western medicine > conventional western medicine.(2)In terms of reducing brain natriuretic peptide(BNP), the SUCRA ranking was Danhong Injection + conventional western medicine > Xinmailong Injection + conventional western medicine > Yiqi Fumai Injection + conventional western medicine > Shenfu Injection + conventional western medicine > Shenmai Injection + conventional western medicine > Puerarin Injection + conventional wes-tern medicine > Shengmai Injection + conventional western medicine > conventional western medicine.(3)In terms of reducing N-terminal pro-brain natriuretic peptide(NT-proBNP), the SUCRA ranking was Shenmai Injection + conventional western medicine > Yiqi Fumai Injection + conventional western medicine > Xinmailong Injection + conventional western medicine > Shengmai Injection + conventional western medicine > Shenfu Injection + conventional western medicine > Puerarin Injection + conventional western medicine > Danhong Injection + conventional western medicine > conventional western medicine.(4) In terms of improving the left ventricular ejection fraction(LVEF), the SUCRA ranking was Shenmai Injection + conventional western medicine > Xinmailong Injection + conventional western medicine > Shenfu Injection + conventional western medicine > Yiqi Fumai Injection + conventional western medicine > Puerarin Injection + conventional western medicine > Danhong Injection + conventional western medicine > Shengmai Injection + conventional western medicine > conventional western medicine.(5) In terms of decreasing the left ventricular end-diastolic diameter(LVEDD), the SUCRA ranking was Shenmai Injection + conventional western medicine > Shenfu Injection + conventional western medicine=Xinmailong Injection + conventional western medicine > Shengmai Injection + conventional western medicine > Yiqi Fumai Injection + conventional western medicine > conventional western medicine > Puerarin Injection + conventional western medicine.(6) In terms of increasing the 6-min walk trail(6MWT), the SUCRA ranking was Xinmailong Injection + conventional western medicine > Shenfu Injection + conventional western medicine > Shenmai Injection + conventional western medicine > Yiqi Fumai Injection + conventional western medicine > conventional western medicine.(7) In terms of reducing the Minnesota heart failure quality of life scale(MLHFQ) scores, the SUCRA ranking was Xinmailong Injection + conventional western medicine > Shenmai Injection + conventional western medicine > Shenfu Injection + conventional western medicine > conventional western medicine.(8)In terms of safety, the group of Chinese medicine injection combined with conventional western medicine had lower incidence of adverse reactions than the control group. The current evidence shows that combining Chinese medicine injection with conventional western medicine treatment can improve the therapeutic effect on acute heart failure, with high safety. Due to the limited number and quality of included studies, the above conclusions need to be verified by more high-quality 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. Odds ratios (OR) with 95% confidence interval (95%CI) were calculated. We further examined the relationship between the positive number of the significant predictive factors and the LNM rate. RESULTS: The tumor diameter (OR = 13.438, 95%CI: 1.773-25.673, P = 0.029), lymphatic vessel involvement (LVI) (OR = 38.521, 95%CI: 1.975-68.212, P = 0.015) and depth of invasion (OR = 14.981, 95%CI: 1.617-52.844, P = 0.024) were found to be independent risk factors for LNM by multivariate analysis. For the 138 patients diagnosed with poorly differentiated EGC, 21 (15.2%) had LNM. For patients with one, two and three of the risk factors, the LNM rates were 7.7%, 47.6% and 64.3%, respectively. LNM was not found in 77 patients that did not have one or more of the three risk factors. CONCLUSION: ESD might be sufficient treatment for intramucosal poorly differentiated EGC if the tumor is less than or equal to 2 cm in size and when LVI is absent upon postoperative histological examination. ESD with LLND may lead to the elimination of unnecessary gastrectomy in poorly differentiated EGC.

[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. This paper reviewed the research progress in the wetland landscape change based on GIS and RS from the aspects of the research methods of wetland landscape pattern, index of wetland landscape pattern, and driving forces of wetland landscape pattern evolution, and discussed the applications of the combination of GIS and RS in monitoring the wetland landscape pattern change, the index selection of wetland landscape pattern, and the driving mechanisms of the combined action of human and nature. Some deficiencies in the current studies were put forward, and the directions of the future-studies were prospected.
