Objective To explore the efficacy and safety of oral solution of magnesium sodium potassium sulfate in bowel preparation before colonoscopy. Methods Patients who planned to undergo colonoscopy at the digestive department of the Ninth People’s Hospital, affiliated to School of Medicine of Shanghai Jiao Tong University from January 2023 to August 2023 were selected and eligible subjects were divided into two groups: Group A took polyethylene glycol （PEG） and Group B took oral solution of magnesium sodium potassium sulfate （OSS）. The quality, drug tolerance, and safety of intestinal preparation were evaluated. The quality of bowel preparation was evaluated by the boston bowel preparation scale （BBPS）. Results The right colon BBPS score of Group B was (2.39±0.82) points, which was significantly higher than of Group A (2.11±0.43) points （P<0.05）. The overall score of Group B was higher than that of Group A （P<0.05）. OSS was easier to take than PEG, with a good taste and overall sensation. Patients were willing to use OSS to clean their bowels even when they were willing to undergo another examination （P<0.05）. There was a significant difference in nausea and vomiting symptoms between the two groups （P<0.05）, and there were no significant changes in renal function and electrolytes before and after medication in the two groups of patients. Conclusion OSS had a higher quality of bowel cleaning and was easier for patients to accept.

This study aims to explore whether Naoxintong Capsules improve multiple cerebral infarctions and myocardial injury via promoting angiogenesis, thereby exerting a simultaneous treatment effect on both the brain and heart. Male SD rats were randomly divided into six groups: sham-operated group, model group, high-dose, medium-dose, and low-dose groups of Naoxintong Capsules(440, 220, and 110 mg·kg~(-1)), and nimodipine group(10.8 mg·kg~(-1)). Rat models of multiple cerebral infarctions were established by injecting autologous thrombus, and samples were collected and tested seven days after modeling. Evaluations included multiple cerebral infarction model assessments, neurological function scores, grip strength tests, and rotarod tests, so as to evaluate neuromotor functions. Morphological structures of brain and heart tissue were observed using hematoxylin-eosin(HE) staining, Nissl staining, and Masson staining. Network pharmacology was employed to screen the mechanisms of Naoxintong Capsules in improving multiple cerebral infarctions and myocardial injury. Neuronal and myocardial cell ultrastructures were observed using transmission electron microscopy. Apoptosis rate in brain neuronal cells was detected by TdT-mediated dUTP nick end labeling(TUNEL) staining, and reactive oxygen species(ROS) levels in myocardial cells were measured. Immunofluorescence was used to detect the expression of platelet endothelial cell adhesion molecule-1(CD31), antigen identified by monoclonal antibody Ki67(Ki67), hematopoietic progenitor cell antigen CD34(CD34), and hypoxia inducible factor-1α(HIF-1α) in brain and myocardial tissue. Western blot, and real-time quantitative polymerase chain reaction(RT-qPCR) were used to detect the expression of HIF-1α, vascular endothelial growth factor(VEGF), vascular endothelial growth factor receptor 2(VEGFR2), sarcoma(Src), basic fibroblast growth factor(bFGF), angiopoietin-1(Ang-1), and TEK receptor tyrosine kinase(Tie-2). Compared with the model group, the medium-dose group of Naoxintong Capsules showed significantly lower neurological function scores, increased grip strength, and prolonged time on the rotarod. Pathological damage in brain and heart tissue was reduced, with increased and more orderly arranged mitochondria in neurons and cardiomyocytes. Apoptosis in brain neuronal cells was decreased, and ROS levels in cardiomyocytes were reduced. The microvascular density and endothelial cells of new blood vessels in brain and heart tissue increased, with increased overlapping regions of CD31 and Ki67 expression. The relative protein and mRNA expression levels of HIF-1α, VEGF, VEGFR2, Src, Ang-1, Tie-2, and bFGF were elevated in brain tissue and myocardial tissue. Naoxintong Capsules may improve multiple cerebral infarctions and myocardial injury by mediating HIF-1α/VEGF expression to promote angiogenesis.

Following the core outcome set standards for development(COS-STAD), this study aims to construct core outcome set(COS) for clinical research on traditional Chinese medicine(TCM) treatment of simple obesity. Firstly, a comprehensive review was conducted on the randomized controlled trial(RCT) and systematic review(SR) about TCM treatment of simple obesity that were published in Chinese and English databases to collect reported outcomes. Additional outcomes were obtained through semi-structured interviews with patients and open-ended questionnaire surveys for clinicians. All the collected outcomes were then merged and organized as an initial outcome pool, and then a preliminary list of outcomes was formed after discussion by the working group. Subsequently, two rounds of Delphi surveys were conducted with clinicians, methodology experts, and patients to score the importance of outcomes in the list. Finally, a consensus meeting was held to establish the COS for clinical research on TCM treatment of simple obesity. A total of 221 RCTs and 12 SRs were included, and after integration of supplementary outcomes, an initial outcome pool of 141 outcomes were formed. Following discussions in the steering advisory group meeting, a preliminary list of 33 outcomes was finalized, encompassing 9 domains. Through two rounds of Delphi surveys and a consensus meeting, the final COS for clinical research on TCM treatment of simple obesity was determined to include 8 outcomes: TCM symptom scores, body mass index(BMI), waist-hip ratio, waist circumference, visceral fat index, body fat rate, quality of life, and safety, which were classified into 4 domains: TCM-related outcomes, anthropometric measurements, quality of life, and safety. This study has preliminarily established a COS for clinical research on TCM treatment of simple obesity. It helps reduce the heterogeneity in the selection and reporting of outcomes in similar clinical studies, thereby improving the comparability of research results and the feasibility of meta-analysis and providing higher-level evidence support for clinical practice.

ObjectiveTo observe the effects of Tongluo Baoshen prescription （TLBS）-containing serum on the rat podocyte injury induced by lipopolysaccharide （LPS） and explore the potential mechanisms. MethodsSD rats were used to prepare the blank serum， losartan potassium-containing serum， and low-， medium-， and high-dose TLBS-containing sera. Rat podocytes were cultured in vitro， and the effects of drug-containing sera on podocyte viability were detected by the cell counting kit-8 （CKK-8） method. The optimal intervention volume fraction of drug-containing sera and the optimal concentration of LPS for inducing the podocyte injury were determined. Rat podocytes were grouped as follows： normal control （NC， 10% blank serum）， model control （MC， 20.00 mg·L^-1 LPS+10% black serum）， losartan potassium （LP， 20.00 mg·L^-1 LPS+10% losartan potassium-containing serum）， low-dose TLBS （TLBS-L， 20.00 mg·L^-1 LPS+10% low-dose TLBS-containing serum）， medium-dose TLBS （TLBS-M， 20.00 mg·L^-1 LPS+10% medium-dose TLBS-containing serum）， and high-dose TLBS （TLBS-H， 20.00 mg·L^-1 LPS+10% high-dose TLBS-containing serum）， and the interventions lasted for 48 h. The ultrastructure of podocytes was observed under a transmission electron microscope. The podocyte apoptosis was detected by the terminal deoxynucleoitidyl transferase mediated nick-end labeling （TUNEL） kit. Immunofluorescence was used to detect the expression of gasdermin D N-terminal fragment （GSDMD-NT） in podocytes. The mRNA and protein levels of G protein-coupled receptor family C group 5 member B （GPRC5B）， nuclear factor-κB （NF-κB） p50， NF-κB p52， NF-κB p65， Rel B， c-Rel， NOD-like receptor protein 3 （NLRP3）， cysteinyl aspartate-specific protease-1 （Caspase-1）， GSDMD-NT， interleukin （IL）-1β， IL-18， nephrin， integrin α₃， and integrin β₁ in podocytes were determined by real-time quaritiative polymerase chain reaction （Real-time PCR） and Western blot， respectively. ResultsCompared with the NC group， the MC group showed reduced podocyte protrusions and organelles， segmental missing of cell membranes， increased and swollen mitochondria， irregular nuclear membranes， light chromatin， increased TUNEL fluorescence-positive nuclei （P<0.01）， obviously enhanced fluorescence intensity of GSDMD-NT， up-regulated mRNA and protein levels of GPRC5B， NF-κB p50， NF-κB p52， NF-κB p65， Rel B， c-Rel， NLRP3， caspase-1， GSDMD-NT， IL-1β， and IL-18 （P<0.01）， and down-regulated mRNA and protein levels of nephrin， integrin α₃， and integrin β₁ （P<0.01） in podocytes. Compared with the MC group， the LP， TLBS-M， and TLBS-H groups showed improved ultrastructure of podocytes with increased protrusions， intact cell membranes， reduced organelles， and alleviated mitochondrial swelling， decreased TUNEL fluorescence-positive nuclei （P<0.01）， weakened fluorescence intensity of GSDMD-NT， down-regulated mRNA and protein levels of GPRC5B， NF-κB p50， NF-κB p52， NF-κB p65， Rel B， c-Rel， NLRP3， caspase-1， GSDMD-NT， IL-1β， and IL-18 （P<0.01）， and up-regulated mRNA and protein levels of nephrin， integrin α₃， and integrin β₁ （P<0.05， P<0.01）. Moreover， the changes above were the most obvious in the TLBS-H group. ConclusionThe TLBS-containing serum can regulate the GPRC5B/NF-κB/NLRP3 pathway to inhibit pyroptosis， thereby ameliorating the podocyte injury induced by LPS.

Obesity has become a major global public health issue,and the situation in China is also becoming increasingly severe.Adipose tissue is categorized into white adipose tissue(WAT)and brown adipose tissue(BAT),which regulates metabolic homeostasis by secreting various adipokines.Mitochondria,as the core organelles of energy metabolism,its dysfunction are closely related to obesity.In the state of obesity,mitochondrial dynamics imbalance,oxidative stress,and metabolic dysfunction can all lead to energy metabolism disorders and adipose tissue dysfunction.Moreover,mitochondrial dysfunction not only affects adipose tissue but also extends to multiple organs such as muscles and livers,thereby exacerbating obesity and related metabolic diseases.In recent years,although numerous therapeutic strategies targeting mitochondrial dysfunction have been actively explored,their clinical translation faces challenges.This review explores the association between mitochondrial dysfunction in adipose tissue and obesity,analyses its mechanism and existing treatment strategies,aiming to provide a new perspective for the diagnosis and treatment of obesity.
