Objective:To analyze the current employment status and the reasons for not engaging in general practice among general practice residents who completed training during 2018-2020.Methods:This study was a cross-sectional study. A questionnaire survey on the current employment was conducted among general practice residents who completed redidency training from 2018 to 2020, participants were selected by stratified random sampling in 57 training centers from each 5 provinces(municipalities) of the eastern, middle and western regions in China. The reasons for not engaging in general practice were investigated through telephone contact.Results:Of the 1 037 general practice residents who responded to the questionnaire, 677 residents(65.3%, 677/1 037) were engaged in general practice after training, while 360 residents(34.7%, 360/1 037) left general practice career or were awaiting employment. The three provinces with the highest proportion of residents leaving general practice career were Hubei(76.5%, 26/360), Sichuan(74.4%, 29/360) and Shandong provinces(59.6%, 28/360). There were significant differences in proportion of residents leaving general practice career after completing the training among eastern, middle and western regions(χ 2=42.911, P<0.001). A total of 261 participants(25.2%, 261/1 037) were engaged in non-general practice clinical career like internal medicine, surgery, gynecology, pediatrics or medical imaging; and the proportion in the eastern(27.3%, 67/245) and middle(33.3%, 106/318) regions was significantly higher thant that in the western region(18.6%, 88/474)(χ 2=6.855, P<0.05; χ 2=21.651, P<0.05). Among 259(71.9%, 259/360) participants who left general practice career, the main reasons were personal choice(63.3%, 164/259) or employers′ arrangement(22.4%, 58/259); the three provinces with the highest percentage of personal choice were Hubei(92.0%, 23/25), Sichuan(85.2%, 23/27) and Henan provinces(80.0%, 20/25). The proportion of personal choice in the middle region(82.4%, 84/102) was significantly higher than that in the eastern(52.1%, 37/71) and western(50.0%, 43/86) regions(χ 2=16.799, P<0.05; χ 2=20.830, P<0.05). The three provinces with the highest proportion of employers′ arrangement were Xinjiang Uygur Autonomous Region(66.7%, 22/33), Zhejiang province(9/13), and Inner Mongolia Autonomous Region(38.5%, 10/26). The proportion of employers′ arrangement in the western region(41.9%,36/86) was significantly higher than that in the eastern(18.3%, 13/71) and middle(8.8%, 9/102) regions(χ 2=8.980, P<0.05; χ 2=26.186, P<0.05). Conclusions:The majority of general practice residents are engaged in general practice after training. The proportion of residents who left the general practice career and the related reasons in different regions are not the same.

Objective To investigate the effects of cucurbitacin B (CucB) on alleviating skin lesions and inflammation in psoriasis mice via the cGAS-STING signaling pathway. Methods The expression of genes associated with the cGAS-STING signaling pathway in psoriatic lesions and non-lesional skin was analyzed, and hallmark gene set enrichment analysis was performed. The cytotoxicity of CucB on BMDMs was evaluated using the CCK-8 assay. The expression levels of genes and proteins related to the cGAS-STING signaling pathway, along with the secretion of inflammatory cytokines, were measured at different concentrations of CucB using quantitative PCR, Western blotting, and ELISA. Imiquimod-induced psoriasis BALB/c mice were divided into four groups: normal group, model group, low-dose CucB group [0.1 mg/ (kg.d)], and high-dose CucB group [0.4 mg/ (kg.d)], with five mice per group. PASI scoring was performed to assess the severity of psoriasis after 6 days of treatment, and HE staining was conducted to observe pathological damage. Meanwhile, the mRNA levels of inflammatory cytokines and their secretion were detected by qPCR and ELISA. Results Most cGAS-STING signaling-related genes were upregulated in lesional skin of psoriasis patients, and the hallmark gene set enrichment analysis revealed that the most significantly upregulated genes were primarily associated with immune response signaling pathways. CucB inhibited dsDNA-induced phosphorylation of interferon regulatory factor 3 (IRF3) and STING proteins in both bone-marrow derived macrophages(BMDMs) and THP-1 cells. CucB also suppressed dsDNA-induced mRNA expression of IFNB1, TNF, IFIT1, CXCL10, ISG15, and reduced the secretion of cytokines such as IFN-β, IL-1β, and TNF-α in THP-1 cells. In the imiquimod-induced psoriasis mouse model, CucB treatment reduced psoriatic symptoms, alleviated skin lesions, and attenuated inflammation. ELISA and qPCR results showed that CucB significantly reduced serum secretion levels of IL-6, TNF-α, and IL-1β, as well as the mRNA levels of IL23A, IL1B, IL6, TNF, and IFNB1. Conclusion CucB inhibits cytoplasmic DNA-induced activationc of the GAS-STING pathway. CucB significantly attenuates skin lesions and inflammation in IMQ-induced psoriatic mice, and the potential molecular mechanism may be related to the down-regulation of the cGAS-STING pathway.

Objective:To survey the post competency of general practitioners who had completed residency training in China.Methods:This study was a cross-sectional survey. An online questionnaire survey was conducted among general practitioners, institution leaders and patients from January to February 2021. The participants were selected from 45 general practice residential training bases in the eastern, central and western regions of China by a combination of stratified sampling and proportional random sampling methods. The post competency self-assessment questionnaire was used for the general practitioners, and the competency evaluation questionnaire was used for institution leaders and the patients.Results:A total of 677 valid self-assessment questionnaires were returned from general practitioners, 600 from institution leaders, and 2 579 from patients. The professionalism and humanistic literacy of the self-assessment questionnaire had the highest score (4.41±0.60),and the teaching, learning and research abilities had the lowest score(3.57±0.84). There was no significant difference in the post competency score of general practitioners among different regions ( P>0.05). The highest score of general practitioners′ post competency evaluated by leaders was the professionalism and humanistic literacy (4.64±0.57), and the lowest one was the basic public health service ability (4.31±0.95). The score of professionalism and humanistic ability in the eastern region was significantly higher than that in the central and western regions ( P<0.05). The highest score of general practitioners′ post competency evaluated by patients was the professionalism and humanistic literacy (4.73±0.55), and the lowest score was the basic medical service ability (4.11±1.35). There were significant differences in scores of the ability for basic medical service, ability for basic public health service, ability for interpersonal communication and ability for professionalism and humanistic literacy among different regions ( P<0.05). For institution leaders, 68.2% (409/600) believed that the general practitioners were fully competent for their current jobs, 28.7% (172/600) believed that the general practitioners were basically competent for their current jobs. For patients, 70.5% (1 817/2 579) were very satisfied with the general practitioners′ service, and 27.1% (700/2 579) were basically satisfied with the general practitioners′ service. Conclusions:The competency of general practitioners who had received training in some provinces is basically up to standard, but the basic public health service ability and teaching, learning and research ability need to be improved.

Objective: This study examined the gut bacterial communities of dogs from different breeds, all kept under identical domestication conditions. Methods: Noninvasive sampling and 16S rRNA high-throughput sequencing were used to compare the composition and function of the gut microbiota of three dog breeds: the Chinese Kunming dog (CKD), German Shepherd dog (GSD), and Belgian Malinois dog (BMD). Results: The gut microbiota of the three dog breeds consisted of 257 species across 146 genera, 60 families, 35 orders, 15 classes, and 10 phyla. The dominant bacterial phyla across the three breeds were Firmicutes (57.44%), Fusobacteriota (28.86%), and Bacteroidota (7.63%), while the dominant bacterial genera across the three breeds were Peptostreptococcus (21.08%), Fusobacterium (18.50%), Lactobacillus (12.37%), and Cetobacter (10.29%). Further analysis revealed significant differences in the intestinal flora of the three breeds at the phylum and genus levels. The intestinal flora of BMD was significantly richer than that of CKD and GSD. The functional prediction and Kyoto Encyclopedia of Genes and Genomes analysis showed that the primary functions of the gut microbiota in these breeds were similar, with significant enrichment in various metabolic pathways, including carbohydrate and amino acid metabolism, secondary metabolite biosynthesis, and microbial metabolism in different environments. The intestinal flora of these breeds also played a crucial role in genetic information processing, including transcription, translation, replication, and material transport. Conclusions and Relevance: These results provide novel insights into the intestinal flora of intervention dogs and suggest novel methods to improve their health status, which help increase microbial diversity and normalize metabolite production in diseased dogs.
