Podocyte infolding glomerulopathy (PIG) is a pathologic type of podocyte glomerulopathy reported recently. The characteristic is that the ultrastructure related to podocytes, such as microspheres and microtubules, are folded into the glomerular basement membrane (GBM) under electron microscope. At present, there are few reports about this disease at home and abroad, and most of them are concentrated in Japan. The clinical characteristics and pathogenesis of PIG are still unclear. In this paper, we report a case of clinical manifestations of nephrotic syndrome, renal biopsy indicated PIG, after the treatment of glucocorticoid, hydroxychloroquine and tacrolimus, the patient's clinical symptoms were relieved and urinary protein decreased.

We report a case of a male patient who developed persistent fever and central nervous system symptoms after eating raw snails for 10 days.

The patient recovered after receiving albendazole anthelmintic and dexamethasone anti-inflammatory therapy. This article incorporates literature review to sort out the diagnosis and treatment of this patient, in order to provide feasible reference for clinicians.

This paper aims to analyze the clinical efficacy of cognitive behavioral therapy for insomnia （CBTI） in chronic insomnia treatment， with a view to providing a theoretical basis for promoting the clinical use of CBTI and providing a reference for the non-pharmacological treatment of chronic insomnia patients in China. Chronic insomnia is a common disorder， and CBTI has emerged as the first approach to treating chronic insomnia， so this review focuses on the current status， clinical efficacy， adverse effects， existed problems and management strategies of CBTI for chronic insomnia treatment from the perspectives of physiological mechanisms and neuroimaging.

Objective:To investigate the enrollment scale and distribution of Master's Degree in Pediatrics programs in China, and to provide a reference for promoting pediatric education and disciplinary development.Methods:Data on colleges and universities authorized to award Master's Degree in Pediatrics in 2023 were collected, sorted, and analyzed for the number, structure, distribution, and enrollment scale and direction of these institutions using descriptive statistics.Results:Among the 117 clinical medicine academic master's degree programs in China, 72 enroll pediatric academic master's degree candidates, with an enrollment of 260 students. Among the 120 master's degree programs in clinical medicine, 104 enroll professional master's degree candidates, enrolling 1 195 students. Enrollment is mainly concentrated in East China, "non-double first-class" colleges and universities, medical colleges and universities with subject level B, and enrollment is carried out in the direction of secondary disciplines.Conclusions:The number of colleges and universities authorized to award Master's Degree in Pediatrics was small, and the distribution of these colleges and universities was unbalanced. The enrollment scale was small and the orientation of Professional Master's Degree was not reasonable. Some colleges and universities were authorized to award Master's Degree in Pediatrics, but did not enroll any students. It is suggested to increase the number of colleges and universities authorized to award Master's Degree in Pediatrics and strengthen the staffing of pediatric departments. The aim is to expand the enrollment scale of candidates for Master's Degree in Pediatrics, improving the differential training of candidates for Academic Master's Degree and Professional Master's Degree, and attach importance to the construction of pediatrics.

OBJECTIVE To assess the long-term cost-effectiveness of five glucagon-like peptide-1 receptor agonists （GLP- 1RAs） in the treatment of poorly controlled type 2 diabetes mellitus （T2DM） treated with metformin. METHODS Baseline data from patients in previously published meta-analysis and included randomized controlled trials （RCTs） were extracted to predict survival， long-term efficacy， and costs for each group using the United Kingdom prospective diabetes study outcome model 2.1. The cost-effectiveness of 5 GLP-1RAs （liraglutide， lixisenatide， exenatide， dulaglutide， and semaglutide） was analyzed by cost- utility analysis. Sensitivity analysis and scenario analysis were also performed to verify the uncertainty of basic analysis results. RESULTS A total of 21 RCTs with 6 796 patients were included. Survival analysis curves showed the superiority of semaglutide in reducing the risk of death from cardiovascular disease and dulaglutide in reducing the risk of all-cause mortality over other GLP- 1RAs. The cost-utility analysis showed that the five drugs were economically superior to inferior in the order of lixisenatide， semaglutide， exenatide， dulaglutide， and liraglutide； one-way and probabilistic sensitivity analyses indicated that the results were robust. The scenario analysis results indicated that the price of semaglutide should decrease by at least 54.64% to 369.21 yuan， which is cost-effectiveness compared to lixisenatide. CONCLUSIONS For T2DM patients in China with poor glycemic control after treatment with metformin， lixisenatide and semaglutide may be considered as the preferred regimen.

Objective:To investigate the current situation of satisfaction with graduate education among recent medical graduates in China, and analyze the differences between different populations, and to propose countermeasures and suggestions.Methods:From June to July 2023, a self-made questionnaire was used to survey 16 903 medical graduates who had recently earned a post-graduate degree from 78 institutions about their satisfaction with curriculum sessions, practical sessions, research training, tutoring, and institutional management. The degrees of satisfaction with education among different populations were compared through the t test and analysis of variance with the use of SPSS 26.0. Results:The scores of satisfaction of the graduates with tutoring, curriculum sessions, practical sessions, institutional management, and research training were 4.44, 4.03, 4.02, 3.90, and 3.82, respectively. Satisfaction scores for individual dimensions were significantly higher for males, doctors, non-transfers, comprehensive universities, non-agricultural household registration, moderate-to-high annual household income per capita, parents with high educational levels, and parents with mid- or senior-level occupations ( P<0.05). Conclusions:There is room for improvement in students' satisfaction with medical graduate education. To improve the quality of medical graduate education, attention should be paid to key populations, education policies, school management, and tutoring to provide appropriate education for different students.

Objective:To analyze the distribution and drug resistance of pathogens of bacterial bloodstream infection in patients with hematological diseases in the Department of Hematology of Tianjin Medical University General Hospital, and to provide etiological data for clinical empirical anti-infection treatment.Methods:A retrospective analysis was conducted on the general clinical information, pathogenic bacteria and drug susceptibility test results of patients with hematological diseases diagnosed with bacterial bloodstream infection by menstrual blood culture in our center from January 2016 to December 2022.Results:Patients included 498 inpatients, with a total of 639 bacterial strains. Among the patients, 86.9% patients had malignancies, and 76.7% had agranulocytosis. Symptoms of concurrent infections, including those of the respiratory tract, oral mucosa, skin and soft tissues, and abdominal sources were observed in 68.3% patients. Gram-negative bacteria (G -) accounted for 79.0% of the isolated bacteria, and gram-positive bacteria (G +) accounted for 21.0%. The top five isolated pathogens were Klebsiella pneumoniae (22.5%), Escherichia coli (20.8%), Pseudomonas aeruginosa (15.0%), Enterococcus faecium (5.5%), and Stenotrophomonas maltophilum (5.0%). Escherichia coli exhibited a decreasing trend of resistance to quinolones, cephalosporins, and carbapenems. Klebsiella pneumoniae exhibited increasing rates of resistance to quinolones and cephalosporins between 2016 and 2018, but the rated decreased after 2019. The resistance rate to carbapenems exhibited by Pseudomonas aeruginosa was approximately 20%. Carbapenem-resistant strains of Pseudomonas aeruginosa strains were first detected in 2017, with a peak resistance rate of 35.7%, detected in 2019. A 60.0% resistance rate to methicillin was observed in methicillin-resistant coagulase-negative staphylococci (MRCNS), and one case of linezolid-resistant MRCNS was detected. Conclusions:Pathogenic bacteria of bacterial bloodstream infections were widely distributed in our center, and precautions are warranted against carbapenem resistant P. aeruginosa and Klebsiella pneumoniae.

BackgroundInsomnia disorder has become a common disease in the current society. Cognitive Behavior Therapy for Insomnia （CBTI） is one of the non-drug treatment methods for insomnia disorder， but relevant studies of its effect on sleep quality and cognitive function of patients with insomnia disorder are limited. ObjectiveTo explore the effects of CBTI on sleep quality and cognitive function in patients with insomnia disorder， so as to provide references for non-drug treatment of insomnia disorder. MethodsA total of 47 patients with insomnia disorder were recruited as the study subjects. They all met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） and have visited Sichuan Mental Health Center from January 2021 to October 2022. The patients underwent CBTI for 6 weeks. Before the treatment， depression and anxiety symptoms were assessed using Hamilton Depression Scale-24 item （HAMD-24） and Hamilton Anxiety Scale （HAMA）. Sleep status and cognitive function were assessed using Pittsburgh Sleep Quality Index （PSQI） and Montreal Cognitive Assessment （MoCA） before and 6 weeks after the treatment. Spearman correlation analysis was used to examine the correlation between the reduction of PSQI score and the increase of MoCA score after treatment. ResultsAfter the 6-week treatment， the factor scores and total score of PSQI across 6 subscales （the sleep quality， sleep onset time， sleep time， sleep efficiency， sleep disorder and daytime dysfunction） were lower than those before the treatment， and the score differences were of statistical significance （t=5.569~15.290， P<0.01）. Both factor and total scores of MoCA across 6 items （visuospatial and executive， naming， attention， language， abstraction and memory） were significantly higher than those before the treatment with score differences reaching statistical significance （t=-11.273~-4.277， P<0.01）. Spearman correlation analysis demonstrated that there was a positive correlation between the decrease in PSQI total score and the increase in MoCA total score after the 6-week CBTI treatment （r=0.323， P=0.027）. ConclusionCBTI may help improve sleep quality and cognitive function in patients with insomnia disorders. The improvement of sleep quality after CBTI intervention may be related to the improvement of cognitive function. ［Funded by Scientific Research Project of Sichuan Provincial Health Commission （number， 19PJ216）］

Neurons in the primary auditory area (AUDp) innervate multiple brain regions with long-range projections while receiving informative inputs for diverse functions. However, the brain-wide connections of these neurons have not been comprehensively investigated. Here, we simultaneously applied virus-based anterograde and retrograde tracing, labeled the connections of excitatory and inhibitory neurons in the mouse AUDp, and acquired whole-brain information using a dual-channel fluorescence micro-optical sectioning tomography system. Quantified results showed that the two types of neurons received inputs with similar patterns but sent heterogeneous projections to downstream regions. In the isocortex, functionally different areas consistently sent feedback-dominated projections to these neurons, with concomitant laterally-dominated projections from the sensory and limbic cortices to inhibitory neurons. In subcortical regions, the dorsal and medial parts of the non-lemniscal auditory thalamus (AT) were reciprocally connected to the AUDp, while the ventral part contained the most fibers of passage from the excitatory neurons and barely sent projections back, indicating the regional heterogeneity of the AUDp-AT circuit. Our results reveal details of the whole-brain network and provide new insights for further physiological and functional studies of the AUDp.
