Objective To investigate the application value of bedside ultrasound monitoring of quadriceps muscle changes in mechanically ventilated children in the early treatment of ICU-acquired muscle weakness (ICU-AW). Methods Eighty-two pediatric ICU patients with mechanical ventilation for>48 hours were selected. On the day of admission (D0) and on day 7 (D7), bedside ultrasound was performed to measure the thickness and cross-sectional area of the rectus femoris and vastus intermedius muscles. Patients were classified using Medical Research Council scores into control group (n = 63) and muscle weakness group (n = 19). Muscle parameters and atrophy rates were compared between groups. Diagnostic performance was assessed using receiver operating characteristic curves. Results The incidence of ICU-AW was 23.17%. At both D0 and D7, the average thickness of the rectus femoris, the average thickness of the vastus intermedius, the average area of the rectus femoris, and the average area of the vastus intermedius were significantly different between the two groups (P<0.05). The atrophy rates of the thickness of the rectus femoris and the area of the vastus intermedius were lower in the control group than in the muscle weakness group at both D0 and D7 (P<0.05). The area under the receiver operating characteristic curve for quadriceps parameters in diagnosing ICU-AW was 0.871, with a sensitivity of 89.47% and a specificity of 79.37%. Conclusion Bedside ultrasound dynamic monitoring of quadriceps changes enables early identification of ICU-AW and provides a basis for clinical intervention.

A 62-year-old male, was admitted to the hospital, with a chief complaint of fever lasting over 10 days and leukopenia and thrombocytopenia for 2 days. Ten days prior to admission, the patient experienced intermittent fever without obvious incentive factors. The breath sounds in both lungs were coarse, without accompanying dry or moist rales. Color Doppler Ultrasound indicated mild splenomegaly and multiple lymphadenectasis in the bilateral cervical, axillary, and inguinal regions. Morphological examination of bone marrow cells demonstrated abnormally large blasts, with some of the nuclei being rather irregular and cytoplasmic vacuoles. Immunophenotyping results identified this group of blast cells as immature monocytes. Karyotype analysis of chromosomes showed clonal abnormalities, with 19 out of 20 cells exhibiting near-tetraploid karyotypes, including complex karyotypic abnormalities involving chromosome17.Targeted next-generation sequencing (NGS) detected gene mutations associated with hematological malignancies that have definite or potential clinical significance,including TP53, SRSF2, STAG2, and ARID2, with variant allele frequencies (VAF) of 63.10%, 30.30%, 0.80%, and 0.60%, respectively. Integrating laboratory findings, the diagnosis was diagnosed as AML-M5 at high-risk. After receiving chemotherapy with the regimen of azacitidine combined with venetoclax, the patient passed away more than 20 days later.

ObjectiveTo provide a new idea for exploring the molecular genetic approach to the pathogenesis of schizophrenia via construction of microRNA-messenger RNA (miRNA-mRNA) regulatory network in schizophrenia. MethodsThe microarray datasets of GSE54578 miRNA expression profiles in peripheral blood and GSE145554 mRNA expression in the anterior cingulate in postmortem brain of schizophrenic subjects were downloaded from Gene Expression Omnibus (GEO) database since July 2021. The GEO2R was used to identify the differentially expressed miRNAs and mRNAs, screen the miRNA with target differentially expressed mRNA, and predict their potential upstream transcription factors. The overlapping genes from the mRNA targeted by the differentially expressed miRNA and the mRNA differentially expressed in GSE145554 dataset were collected. Then the biological features of hub genes were analyzed via Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, and the protein-protein interaction (PPI) network and miRNA-mRNA regulatory network of hub genes were constructed. ResultsA total of 8 up-regulated differentially expressed miRNAs with targeted mRNA were screened out in GSE54578 datasets regarding schizophrenia, which involved in the regulation of 10 transcription factors, 247 down-regulated differentially expressed mRNAs were screened out in GSE145554 datasets, and 17 overlapping mRNAs were obtained. GO analysis showed that the target mRNAs were mainly involved in astrocyte differentiation and development. KEGG pathway enrichment analysis showed that the target mRNAs were mainly involved in Rap1 and Ras signaling pathways. PPI network analysis showed that the mRNAs (KRAS and CD28) might be key genes in schizophrenia. ConclusionThe integrated bioinformatics analysis based on GEO database can identify potential susceptibility genes in schizophrenia, and it also contributes to the construction of miRNA-mRNA regulatory network in schizophrenia.

A total of 207 general practitioners who participated in the "Beijing-Hong Kong Community Health Service Training Demonstration Center Project" training from 2013 to 2017 were selected for this questionnaire survey. A self-designed questionnaire was used, which contained the basic information of the trainees, the training purpose, the shortcomings of training, the satisfaction and suggestions for training. Total 192 valid questionnaires were retrieved with a recovery rate of 92.8%. The in-depth personal interviews were conducted among 8 trainees who served as key trainers in community health service centers and 4 managers from their institutions, to investigate the subsequent application of the learning results after they returning to work. The survey showed that the reasons of participating in training were knowledge updates (165, 85.94%), competence requirements (128, 66.67%), and due to administration decision (127, 66.15%). The highest comprehensive scores of training needs were improvement of general practice thinking ability (4.63), followed by clinical diagnosis and treatment ability (4.44), and general practice skills (3.97). For teaching contents, participants were most interested in diagnosis ability (4.03) and clinical operative techniques (3.20). For the training form, the participants more favored the case discussion method (80.73%, 155/192), clinical practice (52.08%, 100/192) and community practice (38.02%,73/192). The trainees were highly satisfied with the overall training organization, training time, training form, and training teachers of the Beijing-Hong Kong training project, and had a good grasp of the training content. Half of trainees (97, 50.52%) thought that the main shortcomings of training was the discrepancy between training content and practical work. Interviewees showed that after the training, the team management, communication skills and disease management ability for some minor specialties had been significantly improved; the enthusiasm for scientific research had been stimulated; they had a certain managerial thinking; and were able to apply what they leant in community health service. In summary, the training project has reached the initial training goals to promote the comprehensive ability of trainees.

Objective:To compare epidemic characteristics between severe acute respiratory syndrome (SARS) and coronavirus disease 2019 (COVID-19).Methods:The general information, including epidemiological and clinical data of the confirmed cases during the epidemic period of the two infectious diseases was collected. The data of SARS in Guangzhou was derived from the technical files of Guangzhou Center for Disease Control and Prevention (GZCDC), including the statistical report and brief report of the epidemic situation (from January 2 to May 11, 2003);The data of COVID-19 in Wuhan was derived from the epidemic data published by Wuhan health and Health Committee's official website and other publicly reported documents (from December 9, 2019 to March 11, 2020). Descriptive analysis was used for a comparativeanalysis of the time and age characteristics, the number of cases, basic reproduction number (R0), proportion of medical staff in confirmed cases (%), crude mortality, etc.Results:A total of 1 072 cases of SARS in Guangzhou were included in the study. The incidence ratio of male to female was 1∶1.26. 43 cases of death were reported with a mortality rate of 4.01%. The median age was 36 years old. The proportion of medical staff in the early stage of the epidemic was 29.04% (88 cases). As to COVID-19 in Wuhan, a total of 49 978 cases were included, The incidence ratio of male to female was 1.04∶1. The 2 423 cases of death were reported with a mortality rate of 4.85%. The median age was 56 years old. The proportion of medical staff in the early stage of the epidemic was 30.43% (42 cases).Conclusion:The COVID-19 in Wuhan has the characteristics of high incidence and wide population. However, the epidemic situation is falling rapidly, and the prevention and control strategy needs to be adjusted timely. The prevention and control of nosocomial infection should be addressed in future.
