ObjectiveTo investigate the mechanism by which Gegen Qinliantang（GQT） improves skeletal muscle insulin resistance. MethodsThe db/m mice were used as the normal group， while db/db mice were assigned to a model group， low-dose （3.12 g·kg^-1）， medium-dose （6.24 g·kg^-1）， and high-dose （12.48 g·kg^-1） GQT groups， and a Western medicine group （semaglutide， 0.045 mg·kg^-1），n=6 in each group. All groups received corresponding interventions. Intraperitoneal glucose tolerance test （IPGTT）， intraperitoneal insulin tolerance test （IPITT）， and hematoxylin-eosin （HE） staining were used to evaluate insulin resistance and therapeutic efficacy. Serum lipid levels were measured using an automatic biochemical analyzer， and apoptosis in skeletal muscle was assessed via TUNEL assay. Transcriptome sequencing combined with gene ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） analyses was performed to identify differentially expressed genes （DEGs）. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to validate gene expression. Molecular docking was applied to evaluate the binding patterns between active components of GQT and key regulatory genes to elucidate pharmacological mechanisms. ResultsCompared with the model group， the medium-dose and high-dose GQT groups showed significantly reduced fasting blood glucose （FBG） levels （P<0.01）. Triglycerides （TG）， total cholesterol （TC）， and low-density lipoprotein cholesterol （LDL-C） were markedly decreased （P<0.01）， while high-density lipoprotein cholesterol （HDL-C） was significantly increased （P<0.01）. IPGTT， IPITT， and HE staining demonstrated that GQT enhanced insulin sensitivity and restored skeletal muscle morphology. GQT also alleviated apoptosis in skeletal muscle tissue. Transcriptome analysis revealed that GQT primarily affected biological processes such as oxidative phosphorylation， metabolic pathways， cellular processes， and protein binding. Real-time PCR results showed that CBR2， CDK6， F830016B08Rik， IL-1β， Rab27b， and COLEC12 were key regulatory genes. Molecular docking demonstrated that CBR2， IL-1β， Rab27b， and COLEC12 formed stable binding with the main active components of GQT. The therapeutic effects of high- and medium-dose GQT were comparable to those of the semaglutide group. ConclusionGQT improves skeletal muscle insulin resistance， potentially by regulating apoptosis as part of its underlying biological mechanism.

ObjectiveTo investigate the effects of salidroside （SAL） on the impaired bioactivity of endothelial progenitor cells （EPCs） in atherosclerotic （As） mice and the potential mechanisms regarding AMP-activated protein kinase （AMPK）. MethodsAtherosclerosis was induced in 8-week-old male ApoE^-/- mice with high-fat diet. Intragastric administration of SAL was given to one mice group to investigate the effects of SAL on aortic plaque burden， plasma NO level， the migration and angiogenic capabilities of bone marrow-derived EPCs （BM-EPCs）. The proliferation， migration and vasculogenic properties of EPCs isolated from As mice were investigated in vitro. AMPK-sh-RNA or the AMPK inhibitor Compound C was used to investigate the role of AMPK/Akt/eNOS pathway in the regulatory effects of SAL. ResultsCompared with As group， NO level was significantly elevated in SAL group. The sizes of atherosclerotic plaques at the aortic root were reduced with smaller lipid cores in SAL group compared with As group. Moreover， the migration and angiogenesis capacity of EPCs markedly decreased in As mice， while SAL treatment reversed these impairments. Incubation with SAL at concentrations of 20， 40， and 80 μmol/L for 48 hours significantly promoted the proliferation， migration， and angiogenesis of EPCs. AMPK-sh-RNA transfection abrogated the 20 μmol/L SAL improvement in EPC biological activities. Western blot analysis further demonstrated that treatment with Compound C blocked the activation of AMPK/Akt/eNOS signaling pathway induced by SAL. ConclusionSAL upregulates the biological functions of EPCs through activating the AMPK/Akt/eNOS signaling pathway， thereby ameliorating EPC dysfunction during the pathological progression of atherosclerosis.

There was a significant change in the score of doctor-patient communication after the course in the community group (63.00±13.84 vs. 78.69±7.10, t/Z=-4.33, P<0.05) and the residency training group (60.00±15.50 vs. 70.88±6.44, t/Z=-2.12, P<0.05). There was also a significant change in the score of medical record writing after the course in the community group (60.19±17.96 vs. 79.69±14.25, t=-2.96, P<0.05), the specialist group (47.77±12.59 vs. 80.31±12.93, t=-6.26, P<0.05), and the residency training group (37.00±15.50 vs. 75.88±15.88, t=-7.25, P<0.05). The score of medical record writing before the course was 60.19±17.96 in the community group, 47.77±12.59 in the specialist group, and 37.00±15.50 in the residency training group, with a significant difference between the three groups ( χ2=13.04, P=0.001); after the course, the score of medical record writing was 78.69±7.10 in the community group, 63.46±19.40 in the specialist group, and 70.88±6.44 in the residency training group, with a significant difference between the three groups ( χ2=10.13, P=0.006). Conclusions:In the course of clinical reasoning in general practice, BTBL can improve teaching efficiency, save teaching resources, and play the role of promoting strengths and avoiding weaknesses.

The wide application of assisted reproductive technology (ART) has brought the hope of fertility to infertile couples worldwide. However, with the gradual popularization of ART, the long-term health status of ART children has attracted extensive attention from society. Adolescence is a critical developmental period for individuals to transition from childhood to adulthood, with significant physical and psychological changes, so the health status of ART offspring during this period has a profound impact on their overall future health. This article reviews the existing studies, focusing on the effects of ART on multiple aspects of adolescent health, especially growth and development, cardiovascular health, endocrine function, fertility, cancer risk, atopic diseases, mental health, epigenetic changes and other aspects. The possible mechanisms leading to these health problems, including genetic factors, environmental exposures, and the long-term effects of early life interventions, were explored. Future research should continue to explore the long-term effects of ART on the health of offspring and further clarify the mechanisms of these effects, so as to provide a scientific basis for the development of effective prevention and intervention measures.

This study aims to investigate the effect of Lactiplantibacillus plantarum LP12 on obe-sity prevention.In our study,Lactiplantibacillus plantarum LP12 was added to the diet for feed-ing,and the blood biochemistry status of rabbit,as well as the antioxidant effect of serum and liver samples were analyzed by determining the body weight change and feed intake of Japanese White rabbits.The changes in colony structure and abundance were also analyzed by 16S rDNA sequen-cing.The results showed that supplementation of Lactiplantibacillus plantarum LP12 inhibits weight gain,decreases serum glucose and ALT levels,and increases SOD activity in the liver.16S RNA gene sequencing analysis showed that the addition of Lactiplantibacillus plantarum LP12 increases the abundance of Bacteroidetes and Desulfovibrioides at the phylum level,and the supple-mentation of Lactiplantibacillus plantarum LP12 increases the abundance of Muribaculaceae at the genus level.Predictive analysis of microbiota function revealed that the supplementation of Lactiplantibacillus plantarum LP12 positively regulated iron-sulfur clusters and Zn-dependent proteases.In conclusion,the addition of Lactiplantibacillus plantarum effectively inhibits weight gain in Japanese White rabbits,enhances the antioxidative activity of the liver,and induces altera-tions in the gut microbiota composition of these rabbits.These findings lay an experimental foun-dation for further exploring the mechanisms by which Lactobacillus plantarum LP12 exerts its preventive effects against obesity and promotes metabolic health.

Patient-Reported Outcomes(PRO)is a subjective outcome indicator based on the concept of"patient-centered",in which patients report their own information such as health status,functional status,and treatment feelings,which is an ef-fective supplement to traditional objective outcome indicators.Based on the development status of the Patient Reported Outcome Measure(PROM),it systematically analyzed the concepts related to PRO with the goal of clarifying the Patient Experience Data(PED)with research value,and proposed six core types of PROs in the medical field,including health-related quality of life,health preference,health behavior,symptom burden,functional status and patient-reported experience.For each type of PRO,the key characteristics of the study were analyzed,the evidence and application directions of related PED and the production based on PED were described,and the existing international mainstream PROMs were reviewed.It is hoped that the connotation of PRO-related concepts can be comprehensively expounded,and PEDs with research significance and value can be explored,so as to provide guidance for the focus of PRO-related research in China,so as to promote the application and development of PRO in China.

Patient-Reported Outcomes(PRO)refers to a subjective outcome measure based on the concept of"patient-cen-tered",in which patients report their own health status,functional status,treatment feelings and other information,which is an ef-fective supplement to traditional objective outcome indicators.With the continuous promotion of PRO research,its application in the world is also constantly enriched.It takes the different application scenarios of PRO as the starting point and the evidence-based evidence that PRO can generate as the evaluation object,reviews the application status of PRO in the US,the European Union,the UK,Canada and other countries,regions or organizations,and summarizes the main application methods of PRO in different medical decision-making scenarios,in order to provide international experiences for the application research of PRO in China.

Objective To analyze and compare the efficacy of DNA barcode,i.e.,Cytochrome b(Cytb)and 12S ribosomal RNA(12S rRNA)gene sequences,in the species identification of wildlife.Methods DNA extraction,quantification,PCR amplification of Cytb and 12S rRNA gene fragments,Sanger sequencing,and sequence alignment analysis were performed on ten wildlife samples.Results Both gene fragments were successfully amplified in six samples,while Cytb alone was successfully amplified in 1 sample,and 12S rRNA alone in 3 samples.Sequence analysis indicated that Cytb enabled species-level identification for 6 samples(Gallinula chloropus,Streptopelia orientalis,Phasianus colchicus,Falco naumanni,Myiopsitta monachus and Lynx lynx)and genus-level identification for 1 sample(Lepus).In contrast,12S rRNA achieved species-level identificaggion for 8 samples(Gallinula chloropus,Lepus sinensis,Phasianus colchicus,Myiopsitta monachus,Muntiacus reevesi,Macaca mulatta and Lynx lynx),representing seven species,and genus-level identification for 1 sample(Falco).However,by combining Cytb and 12S rRNA,all samples could be identified to the species level.Conclusion When applying DNA barcodes to wildlife identification,the Cytb and 12S rRNA gene regions analyzed here can effectively identify common species such as Gallinula chloropus and Streptopelia orientalis,but face difficulties in distinguishing closely related species within the same genus.Therefore,when conducting wildlife species identification,it is recommended to use two or more DNA barcode markers.

Objective:To evaluate the role of interferon regulatory factor 3 (IRF3) in renal fibrosis in a mouse model of renal ischemia-reperfusion injury.Methods:Twelve male C57BL/6J wild-type mice and 12 macrophage IRF3 conditional knockout C57BL/6J mice, aged 8-10 weeks, weighing 20-25 g, were divided into 2 groups ( n=6 each) using a random number table method: wild-type sham operation group (WT-Sham group) and wild-type renal ischemia-reperfusion injury group (WT-I/R group); IRF3 conditional knockout sham operation group (cKO-Sham group) and IRF3 conditional knockout I/R group (cKO-I/R group). The model of renal I/R injury was established by occluding bilateral renal pedicles for 45 min followed by reperfusion in anesthetized animals. The orbital blood samples and renal tissues were collected at 14 days of reperfusion for determination of the concentrations of blood urea nitrogen (BUN) and creatinine (Cr) in serum, expression of fibronectin, collagen-I, alpha-smooth muscle actin (α-SMA) (by immunofluorescence), F4/80-α-SMA double positive cell count, and mRNA expression of interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) and transforming growth factor-β1 (TGF-β1) in renal tissues (by real-time polymerase chain reaction) and for observation of pathological changes which were scored. The area of renal fibrosis was measured. Results:For two types of mice, compared with group Sham, the levels of serum BUN and Cr, area of renal fibrosis and renal injury score were significantly increased, the expression of fibronectin, COL-Ⅰ and α-SMA protein and IL-6, IL-1β, TNF-α and TGF-β1 mRNA was up-regulated, and the F4/80-α-SMA dual positive cell count was increased in group WT-I/R ( P<0.05). Compared with group WT-I/R, the concentrations of BUN and Cr in serum, area of renal fibrosis and renal injury score were significantly decreased, the expression of fibronectin, COL-Ⅰ and α-SMA protein and IL-6, IL-1β, TNF-α and TGF-β1 mRNA was down-regulated, and the F4/80-α-SMA dual positive cell count was decreased in cKO-I/R group ( P<0.05). Conclusions:IRF3 is involved in the process of renal fibrosis in a mouse model of renal ischemia-reperfusion injury, and the mechanism may be associated with the promotion of inflammatory responses and the transformation of macrophages into myofibroblasts.
