The Effects and Safety of Chinese Herbal Medicine on Blood Lipid Profiles in Placebo-Controlled Weight-Loss Trials: A Systematic Review and Meta-Analysis

Anti-obesity potential of bioactive guided fractions of Annona squamosa linn. leaves extract: a combination of in-vitro, in-vivo and in-silico studies along with profiling of lead compounds by HPTLC MS-MSn method

The antiobesity potential of bioactive fractions derived from Annona squamosa was approached using a combination of in vitro, in silico and in-vivo studies. The study was analyzed to validate and select the potent bioactive fractions of A. squamosa leaves extract through in vitro and in vivo activities targeting obesity. The phytochemical properties of the bioactive fractions were investigated utilizing total flavonoid, total phenolic and total steroidal content. Further, in vitro antioxidant assays such as nitric oxide (NO2), DPPH, ABTS, and Hydrogen peroxide (H2O2) scavenging assays were performed whereas pancreatic lipase, Alpha-amylase and Alpha glucosidase assays were carried out for enzyme inhibition activities. The overall study revealed that fractions F2 and F3 had shown significant in vitro activities targeting obesity. The selected potent fractions (F2 and F3) were orally bio-screened for efficacy in MSG-HFD-induced obese mice at 80 mg/kg/bw. The invivo study confirmed that fractions 2 and 3 with a dose of 80 mg/kg/bw had a significant potency compared to obese control and standard for various parameters. Body weight and lipid metrics were significantly reduced, and histological examinations revealed considerable beneficial alterations in the organs of the animals. Further HPTLC MS-MSn was used to characterize and identify the major compounds in the potent bioactive fractions, which confirmed the presence of seven major compounds: Ascorbic acid, Gallic acid, Quercetin, β-sitosterol, Stigmasterol, Caffeine and Epigallocatechin gallate. An in silico model was then employed to determine the best binding activity of the identified compound towards the specific receptors targeting obesity, confirming the most effective docking score towards stigmasterol and sitosterol. The in vitro and in vivo studies of derived bioactive fractions of A. squamosa leaves extract revealed a possible therapeutic approach towards anti-obesity activity for the first time.

Status of traditional Chinese medicine healthcare services in nursing homes across China

This study aimed to elucidate the status of traditional Chinese medicine (TCM) healthcare services provided in nursing homes across China. We investigated 484 nursing homes using self-compiled questionnaires with a convenient sampling method. Chi-squared and Wilcoxon rank-sum tests were used for univariate analysis and binary logistic regression for multi-factor analysis. Of the 443 nursing homes finally included, 215 (48.5%) provided TCM healthcare services. Nursing home leaders majored in integrated TCM and Western medicine, leaders with a better understanding of TCM and government policies, nursing homes charging over 5,000 CNY/month, and those with ≥500 beds were more likely to provide improved TCM healthcare services. Massage, moxibustion, cupping or scraping, plaster therapy, decocting pieces, and acupuncture were the most prevalent and popular TCM services. Lack of professionals, financial investment, and policy support were the most common factors limiting the provision of TCM healthcare services in Chinese nursing homes.
