Objective:To understand the status quo of general practice postgraduate researches through visualized analysis of masters′ theses.Methods:The master′s theses in general medicine from January 2007 to December 2022 were retrieved from China Knowledge and Wanfang databases. The number and regional distribution of theses, the degree-granting institutions were analyzed; the performed keywords were visualizde with CiteSpace and VOSviewer softwares.Results:A total of 1 688 master′s theses in general practice were included in the analysis. The highest number of theses ( n=345) were published in 2022. The theses from institutions in the eastern, central and western regions of China accounted for 45.67% (771/1 688), 22.16% (374/1 688) and 32.17% (543/1 688), respectively, and those in Shaanxi Province accounted for the highest proportion at 13.68% (231/1 688). A total of 3 755 keywords were included in the theses, and the top three were diabetes mellitus (115/3 755), risk factors (77/3 755) and clinical efficacy (71/3 755). The results of keyword clustering and timeline mapping showed that the research topics were mainly clustered around five themes: clinical treatment and drug efficacy/safety for diabetes mellitus, training of general practitioners and evaluation of general practice services, risk factors related to common chronic diseases in the community, risk factors and cognitive changes in cerebrovascular diseases, and pathogenic mechanisms of cardiovascular diseases. The results of the emergent words showed that recent research hotspots mainly included obesity, older adults, and cognitive function. Conclusions:The number of general practice master′s theses published in China is increasing rapidly with an uneven regional distribution; and the research topics are diverse, mainly focusing on the diagnosis and treatment of chronic diseases and analysis of related risk factors.

Purpose To investigate the clinicopathological features of traditional serrated adenoma(TSA).Methods A retrospective analysis was conducted on the clinical data,endoscopic,and pathological features of 200 TSA patients.HE staining and immunohistochemical staining were performed.The clinical pathological features were statistically analyzed using x2 test,and relevant literature was reviewed.Results There were 114 males(57.0％)and 86 females(43.0％),with ages ranging from 27 to 92 years(mean age 56.2 years).Among the patients,147(73.5％)were aged ≥ 50 years,and 53(26.5％)were aged＜50 years.Of the 207 TSA lesions,143(69.1％)were located in the distal colon and rectum,while 57(27.5％)were in the proximal colon and rectum.Endoscopic features included 72 lesions(34.8％)with a perpendiculated appearance,48 lesions(23.2％)with a flat appear-ance,and some exhibiting a pinecone-like appearance.The maximum diameter of the lesions was ≤ 10 mm in 136 ca-ses(65.7％),and＞10 mm in 71 cases(34.3％).The typical histopathological features of TSA included serrated contours,eosinophilic cytoplasm,pencil-like nuclei,and ectopic crypt foci.The most common pathological type was the classic TSA(152 lesions,73.4％),followed by the mucin-rich TSA(39 lesions,18.8％).12 cases(5.8％)of TSA exhibited high-grade intraepithelial neoplasia(HGIN)and 3 case(1.5％)of TSA progressed to carcinoma,con-sistent with TSA-originated colorectal cancer(TSA-CRC).Immunophenotype:in 34 cases TSA,Ki67 showed diffuse positivity in basal cells and scattered positivity on the surface.In all 35 cases TSA,p53 showed weak positive nuclear positivity(1％to 60％),and PTEN and MLH1 were retained.In the 12 cases of TSA with HGIN and 3 cases of TSA-CRC,Ki67 showed diffusely positive,CK20 was strongly positive diffusely,and MLH1 was retained.In 9 cases of TSA with HGIN,p53 was diffusely strongly positive,and in 12 cases,PTEN was lost.All 3 cases of TSA-CRC showed dif-fuse strong nuclear p53 positivity.The molecular detection showed there were BRAF V600E gene mutation in 8 cases.There were 6 cases with KRAS G12V mutation as well as 1 case with KRAS G13D mutation among the 7 cases of KRAS mutation.The primary surgical approach(111 cases,53.6％)was endoscopic mucosal resection(EMR).Conclu-sion TSA exhibits characteristic histological and endoscopic features.Lesions with a maximum diameter＞10 mum are more likely to progress to HGIN or adenocarcinoma.It is crucial to enhance the awareness of pathologists and clini-cians,particularly regarding TSA with atypical hyperplasia or invasive carcinoma,to avoid misdiagnosis and missed di-agnoses.

Objective:To investigate the impact of perceived barriers to cardiac rehabilitation on adherence to cardiac rehabilitation and the mediating effect of cardiac impact denial in elderly patients after percutaneous coronary intervention (PCI) .Methods:This study was a cross-sectional survey. From August 2023 to July 2024, 336 elderly patients with PCI who were discharged from the First Affiliated Hospital of Wenzhou Medical University and needed phaseⅡ cardiac rehabilitation were selected for the study. General Information Questionnaire, Adherence of Cardiac Rehabilitation Assessment Scale in Patients with Coronary Heart Disease (ACRAS-CHD) , Cardiac Rehabilitation Barriers Scale (CRBS) , and Cardiac Denial of Impact Scale (CDIS) were used to survey the patients. Bootstrap method was used to sample 5 000 for mediating effect tests.Results:A total of 336 questionnaires were distributed and 324 valid questionnaires were recovered, with a valid recovery rate of 96.43% (324/336) . Among 324 elderly patients after PCI, ACRAS-CHD score, CRBS score, and CDIS score were (73.19±5.46) , (79.35±6.60) , and (30.57±3.66) , respectively. The direct effect of perceived barriers to cardiac rehabilitation on adherence to cardiac rehabilitation in elderly patients after PCI was -0.368, which accounted for 74.49% (-0.368/-0.494) of the total effect. The mediating effect of cardiac impact denial between perceived barriers to cardiac rehabilitation and adherence to cardiac rehabilitation in elderly patients after PCI was -0.126, which accounted for 25.51% of the total effect (-0.126/-0.494) .Conclusions:Elderly patients after PCI have poor adherence to cardiac rehabilitation. Perceived cardiac rehabilitation barriers reduce cardiac rehabilitation adherence in elderly patients after PCI, and cardiac impact denial exerts a partial mediating effect between perceived cardiac rehabilitation barriers and cardiac rehabilitation adherence.

ObjectiveTo investigate the correlation among the botanical characteristics， biological characteristics， chemical composition， and medicinal properties and efficacy of traditional Chinese medicines （TCM） from latex-containing plants， so as to strengthen the theory of "identifying symptoms for qualities" and provide a reference for the development and utilization of the latex-containing plant resources. MethodStatistics on the meridians for properties and tastes， efficacy， medicinal parts， family and genus， and chemical components of TCM from latex-containing plants were carried out. A total of 53 TCM from latex-containing plants included in the 2020 edition of the Chinese Pharmacopoeia were screened by mining the Chinese Botanical Journal， Chinese Materia Medica， Dictionary of Traditional Chinese Medicines， and related literature. In addition， their meridians for properties and tastes， medicinal parts， chemical components， and TCM classifications were summarized and statistically analyzed by using Excel 2013 and ChiPlot 2023.3.31 software. ResultIt was found that latex-containing plants were mainly distributed in one kingdom， one phylum， two classes， and 20 families， and most of the TCM from latex-containing plants belonged to Dicotyledonaceae under Angiosperms. In terms of properties and tastes， plain>cold>warm>cool>hot and bitter>pungent>sweet>sour>salty. In terms of meridians， liver>lung>kidney>spleen=large intestine=stomach>heart>bladder=gallbladder=small intestines. In terms of medicinal parts， roots （root， rhizomes， tuberous root， and root bark）>resin>seed>whole herb （whole herb and above-ground part）>stem （stem and branch）>fruit>leaf>flower=skin. In terms of research on chemical components， they were mostly glycosides. In terms of TCM classification， they were mostly medicines for activating blood circulation and removing blood stasis. ConclusionThe TCM from latex-containing plants is mainly plain， with a uniform warm and cold distribution. The tastes are mainly bitter and pungent， and the major meridians are the liver and lung. The roots and resins are mainly used as medicines. The components mostly contain glycosides， alkaloids， and volatile oils， and most of them are medicines for activating blood circulation and removing blood stasis， as well as for removing heat and toxins. There is a certain degree of correlation among the growth habits， medicinal parts， chemical components， and the properties， tastes， and efficacy of the TCM from latex-containing plants. It may provide a reference for resource development and utilization of TCM from latex-containing plants.

ObjectiveThe relevant laws among the biological characteristics， medicinal parts， growth environment， and medicinal properties and efficacy of traditional Chinese medicines （TCM） from fungi were excavated， so as to strengthen the theory of distinguishing symptoms for quality and provide a reference for the development and utilization of TCM from fungi. MethodThe medicinal parts， meridians for properties and tastes， heterotrophic mode， and efficacy of commonly used TCM from fungi were summarized. By consulting the Compendium of Materia Medica， Shennong Materia Medica， Flora of China， and literature， the TCM from fungi indexed in the 2020 edition of the Chinese Pharmacopoeia and some local pharmacopeias were checked. ResultA total of 28 common TCM from fungi were selected. Different TCMs from fungi have different meridians for properties and tastes， medicinal parts， habits， and growth environments. The relevant information was counted. Among the four properties， plain>cold>warm. Among the five tastes， sweet>bitter>light>pungent=salty. In terms of medicinal parts， fruiting body>sclerotia>complex>spermia=outer skin=other. In terms of meridians， lung>liver=heart>spleen=kidney>stomach. In terms of habits， parasitism>saprophysis>symbiosis=facultative parasitism=facultative saprophysis. ConclusionTCM from fungi are mainly parasitic and saprophytic， and the plain property and sweet taste the most. The meridians are mostly lung， heart， and liver. Nourishment and diuresis are the main efficacy. There is a certain correlation between the color， habit， medicinal parts， and growth environment of TCM from fungi and their properties， tastes， and efficacy， providing comprehensive literature reference and theoretical basis for their in-depth research， clinical use， and resource development.

ObjectiveTo investigate the functions and characteristics of traditional Chinese medicine （TCM） from plant skin and their Chinese patent medicines and explore the related laws of the medicinal tissue， property， taste， efficacy， and clinical application， so as to strengthen the theory of identifying symptoms for qualities and provide references for the development and utilization of TCM from plant skin and their Chinese patent medicines. MethodBy reviewing the 2020 edition of the Chinese Pharmacopoeia and some local pharmacopeias， TCM from plant skin and their Chinese patent medicines were screened out， and the characteristics， functions， and precautions of TCM from plant skin and their Chinese patent medicines were summarized. Statistical analysis was carried out with Excel. ResultA total of 62 TCM from plant skin were found， mainly distributed in one kingdom， three phyla， and 31 families. In terms of the family genus， Rutaceae>Leguminosae>Cucurbitaceae. In terms of the medicinal tissue， bark>root bark>fruit bark>seed bark. In terms of property and taste， warm>cold>plain>cool>hot， and bitter>sweet=pungent>acidic. In terms of meridians， lung>liver>spleen>heart>colorectal>kidney>stomach=bladder. In terms of TCM classification， most of them belong to the category of heat-clearing medicines. There were 485 types of Chinese patent medicines from plant skin， with the most Chinese patent medicines containing Citri Reticulatae Pericarpium. Among the forms of administration， pills were the most predominant. In terms of the tastes of the medicines， bitter and sweet flavors predominated. In terms of functions， medicines for strengthening the body resistance were the most. For the precautions， contraindications during pregnancy were the most common. ConclusionThere is a correlation among medicinal tissue， property， taste， efficacy， and clinical application of TCM from plant skin. It is also necessary to pay attention to the contraindications of the medicines and rationally choose TCM from plant skin and their Chinese patent medicines under the guidance of TCM theory based on syndrome differentiation and treatment.

Morita therapy has been bom for more than 100 years.Inpatient Morita therapy is highly oper-able and easy to master.It can improve many refractory neuroses through four-stage treatment.But more neuroses are treated in outpatient clinics,and Morita therapy cannot be used in hospitalized patients.Therefore,the formula-tion of expert opinions on outpatient operations is particularly important.This paper is based on domestic and for-eign references,and after many discussions by domestic Morita therapy experts,and then drew up the first version of the expert opinions on operation of outpatient Morita therapy.Meanwhile the operation rule of Morita therapy in three stages of outpatient treatment was formulated:in the etiological analysis stage,under the theoretical guidance of Morita therapy,analyze the pathogenic factors,to improve treatment compliance and reduce resistance;during the operating stage,guide patients to engage in constructive and meaningful actions,realizing the achievement of letting nature take its course principle;in the cultivating character and enriching life stage,pay attention to positive infor-mation,expanding the scope and content of actions,improving the ability to adapt to complex life,and preventing recurrence caused by insufficient abilities.It will lay a foundation for the promotion of Morita therapy in domestic outpatient clinics,so that more patients with neurosis and other psychological diseases could receive characteristic Morita therapy treatment in outpatient clinics.
