ObjectiveTo investigate the mechanism of Acanthopanacis Senticosi Radix et Rhizoma seu Caulis extract （ASH） in treating Parkinson's disease （PD） in mice by Data-Independent Acquisition （DIA） proteomics. MethodsThe α-Synuclein （α-Syn） transgenic PD mice were selected as suitable models for PD， and they were randomly assigned into PD， ASH （61.25 mg·kg^-1）， and Madopar （97.5 mg·kg^-1） groups. Male C57BL/6 mice of the same age were selected as the control group， with eight mice in each group. Mice were administrated with corresponding drugs by gavage once a day for 20 days. The pole climbing time and the number of autonomic activities were recorded to evaluate the exercise ability of mice. Hematoxylin-eosin staining was employed to observe neuronal changes in the substantia nigra of PD mice. Immunohistochemistry （IHC） was employed to measure the tyrosine hydroxylase （TH） activity in the substantia nigra and assess the areal density of α-Syn in the striatum. DIA proteomics was used to compare protein expression in the substantia nigra between groups. IHC was utilized to validate key differentially expressed proteins， including Lactotransferrin， Notch2， Ndrg2， and TMEM 166. The cell counting kit-8 （CCK-8） method was used to investigate the effect of ASH on the viability of PD cells with overexpression of α-Syn. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were employed to determine the protein and mRNA levels of Lactotransferrin， Notch2， Ndrg2， and TMEM 166 in PD cells. ResultsCompared with the control group， the model group showed prolonged pole climbing time， diminished coordination ability， reduced autonomic activities （P<0.01）， and reduced swelling neurons. Compared with the model group， ASH and Madopar reduced the climbing time， increased autonomic activities （P<0.01）， and ameliorated neuronal damage. Compared with the control group， the model group showed a decrease in TH activity in the substantia nigra and an increase in α-Syn accumulation in the striatum （P<0.01）. Compared with the model group， the ASH group showed an increase in TH activity and a reduction in α-Syn accumulation （P<0.05）. DIA proteomics revealed a total of 464 differentially expressed proteins in the model group compared with the control group， with 323 proteins being up-regulated and 141 down-regulated. A total of 262 differentially expressed proteins were screened in the ASH group compared with the model group， including 85 proteins being up-regulated and 177 down-regulated. Kyoto encylopedia of genes and genomes （KEGG） pathway analysis indicated that ASH primarily regulated the Notch signaling pathway. The model group showed up-regulation in protein levels of Notch2， Ndrg2， and TMEM 166 and down-regulation in the protein level of Lactotransferrin compared with the control group （P<0.01）. Compared with the model group， ASH down-regulated the protein levels of Notch2， Ndrg2， and TMEM 166 （P<0.05） while up-regulating the protein level of Lactotransferrin （P<0.01）. The IHC results corroborated the proteomics findings. The cell experiment results showed that compared with the control group， the modeling up-regulated the mRNA and protein levels of Notch2， Ndrg2， and TMEM 166 （P<0.01）， while down-regulating the mRNA and protein levels of Lactotransferrin （P<0.01）. Compared with the model group， ASH reduced the mRNA and protein levels of Notch2， Ndrg2， and TMEM 166 （P<0.01）， while increasing the mRNA and protein levels of Lactotransferrin （P<0.05， P<0.01）. ConclusionASH may Synergistically inhibit the Notch signaling pathway and mitigate neuronal damage by down-regulating the expression of Notch2 and Ndrg2. Additionally， by up-regulating the expression of Lactotransferrin and down-regulating the expression of TMEM166， ASH can address brain iron accumulation， intervene in ferroptosis， inhibit mitophagy， and mitigate reactive oxygen species damage， thereby protecting nerve cells and contributing to the treatment of PD.

General practice standardized residency training is a crucial part of postgraduate education for cultivating general practitioner. The factors influencing the quality of general practice residency training cover various aspects such as the residents themselves, teaching staff, management and decision-making levels, as well as teaching resources. Guided by the goal of "fostering virtue through education", and integrated the spirit of Norman Bethune and modern innovation theories and the educational philosophy, the China-Japan Union Hospital of Jilin University has carried out comprehensive reforms in this field. It has constructed a PDCA cycle management system based on the concept of total quality management to improve the quality of education from multiple links such as quality planning and process monitoring. In terms of faculty development, based on the dissipative structure theory, a mechanism of "selection, evaluation, incentive, and elimination" has been established. Teacher communities have been formed and a training college has been established to strengthen the teaching team. In terms of platform construction, the linkage between "teaching base-community" and "on campus-off campus" has been strengthened and resources have been integrated. The reform has achieved remarkable results, and our practice may provide a reference for general practice medical education.

Objectives:This study aimed to investigate the impact of quantitative flow ratio(QFR)-guided revascularization on outcome of elderly patients with coronary artery disease(CAD)undergoing valve surgery.Methods:We retrospectively analyzed 750 consecutive patients with angiographically confirmed CAD(≥50%stenosis)who underwent valve surgery at Zhongshan Hospital,Fudan University,between January 2016 and December 2021.According to the patients'ages,they were divided into the younger group(age<70 years old,n=532)and the elderly group(age≥70 years old,n=218).Revascularization strategies were evaluated using anatomical(angiography-based)and functional(QFR-based)criteria.Anatomical complete revascularization(CR)was defined as bypass grafting for all lesions with≥70%diameter stenosis in major coronary arteries or≥50%stenosis in the left main coronary artery.Functional CR referred bypass grafting for all lesions with QFR≤0.80.Incomplete revascularization(ICR)was defined as failure to meet CR criteria.According to the anatomical and functional definitions,the younger group and the elderly group were further divided into the incomplete revascularization subgroup and the complete revascularization subgroup respectively.Major adverse cardiovascular events(MACE),including death,myocardial infarction,repeat revascularization,and stroke,were assessed as the composite endpoint.Results:Over a follow-up of(3.7±1.8)years,the overall MACE rate was 13.3%.The younger group exhibited significantly lower MACE rates than the elderly group(10.7%vs.19.7%,P=0.001).In the younger group,anatomical ICR did not increase MACE risk(HR=1.46,95%CI:0.81-2.62,P=0.164),whereas functional ICR significantly increased MACE risk(HR=2.27,95%CI:1.24-4.15,P=0.001).In the elderly group,neither anatomical ICR(HR=1.22,95%CI:0.62-2.41,P=0.540)nor functional ICR(HR=1.52,95%CI:0.78-2.96,P=0.172)was associated with increased MACE risk.Conclusions:In patients undergoing valve surgery with CAD,functional ICR correlated with adverse outcomes in the younger group,whereas neither anatomical nor functional ICR significantly affected prognosis in elderly patients.These findings suggest that a moderately conservative revascularization strategy may be more appropriate for elderly populations.

Community acquired pneumonia (CAP) is one of the common infectious diseases in clinic, with a high mortality. With the aging population, continuous variation of pathogens, and increasingly severe antibiotic resistance, the treatment difficulty of CAP continues to increase. This disease belongs to the categories of traditional Chinese medicine diseases such as " wind warm lung heat disease" and " cough". Traditional Chinese medicine treatment can effectively improve symptoms of CAP, control disease progression, shorten hospital stay, and also have certain advantages in prevention. This article mainly provides an overview of the diagnosis, etiology and pathogenesis, syndrome differentiation and treatment, and prevention of CAP, providing reference for the clinical diagnosis, treatment, and prevention of CAP in traditional Chinese medicine.

Objective To study the in-vitro anti-tumor activities of physalin B (PhB) extracted from Physalis angulata L.. Methods Th e effect of PhB on the cell proliferation and the morphology changes of tumor cell strains HepG2 and SGC7901 was observed by methyl thiazolyl tetrazolium (MTT) assay and by phase contrast microscopy respectively, and the results were compared to positive control anti-cancer drug hydroxycamptothecine (HCTP) . Apoptosis of HepG2 and SGC7901 cells induced by PhB was determined by 4’ , 6-diamidino-2-phenylindole ( DAPI) staining method. Results MTT results showed that the growth of HepG2 and SGC7901 was significantly inhibited by PhB in dose-and time-dependent manner, and the inhibitory effect of high concentration of PhB was better than the positive control medicine HCTP. Phase contrast microscopy results showed that the cellular morphology was improved by PhB, which was accorded with the results showed by MTT assay. DAPI staining results showed that the apoptosis of HepG2 and SGC7901 was enhanced by PhB. Conclusion PhB extracted from Physalis pubescens L. exerts certain inhibitory effect on the proliferation of HepG2 and SGC7901 cells.

Objective To explore the effects of zinc finger E-box binding protein (ZEB)2 3′UTR gene transfection on proliferation, invasion and migration in human gastric epithelial cell line GES-1. Methods The synthetic ZEB2 3′UTR and miR-200b micmics were transfected into GES-1 cell line by lipofectamine 2000. We set up control grop, the mutation group and ZEB2 3′UTR group. Real-time quantitative PCR was performed to evaluate the expression levels of miR-200a/b/c and ZEB1/ZEB2 mRNAs after transfection.And then we set up control group, ZEB2 3′UTR group, ZEB2 3′UTR+negative control group and ZEB2 3′UTR+miR-200b micmics group. The protein expression levels of ZEB1, ZEB2, matrix metallopro-teinases (MMP) 2/9 and proliferating cell nuclear antigen (PCNA) were detected by Western blot assay. The invasion and mi-gration capability were analyzed by transwell assay and wound healing test. MTT assay was used to detect the proliferation ability. Results Compared with control group and mutation group, the expressions of miR-200a/b/c were significantly de-creased, especially for miR-200b. And the expressions of ZEB1/ZEB2 were significantly increased at both mRNA and pro-tein levels after transfected with the ZEB2 3′UTR, enhancing the capability of migration,invasion,and proliferation (P <0.05). Compared with ZEB2 3′UTR group, the capabilities of proliferation,invasion and migration were significantly lower in combined group. Conclusion ZEB2 3′UTR can increase the ability of cell proliferation, invasion and metastasis through regulating the levels of miR-200a/b/c, and then influence the regulation of transcription of the target gene, which could lead to malignant transformation of GES-1 cells.

Objective:To explore the effect and mechanism of miRNA sponge on the epithelial-mesenchymal transition (EMT) of gastric carcinoma cell lines SGC7901. Methods:Synthetic ZEB2 3'UTR plasmid and siRNA targeting ZEB2 were transfected into the SGC7901 cell line by Lipofectamine 2000. Real-time quantitative polymerase chain reaction was performed to evaluate the expres-sion levels of miR-200a/b/c. Finally, the migratory, invasive, and proliferative activities of the gastric carcinoma cells in vitro were ana-lyzed by the scratch test, the Transwell cell invasion, and the cell cloning assay. The expression of the target protein was detected by Western blot. Results:Compared with the control group, the expressions of miR-200a/b/c significantly decreased, and their migration, invasion, and proliferation capabilities were considerably higher after they were transfected with ZEB2 3'UTR. Although the expres-sions of miR-200a/b/c significantly increased, the migratory, invasive, and proliferative activities of SGC7901 cells also degraded after they were transfected with siRNA targeting ZEB2. The expression of ZEB2 increased, and that of E-cadherin decreased at the protein level after they were transfected with ZEB2 3'UTR. The protein expression of Vimentin in SGC7901 cells significantly increased. The indicators show the opposite trend when cells were transfected with siZEB2, and the differences between the control and mutation groups were insignificant. Conclusion:ZEB2 3'UTR can regulate EMT course by regulating the miR-200a/b/c expression in gastric car-cinoma, consequently regulating the invasion and migration of carcinoma cells.
