Objective To explore the expression level of serum long non-coding RNA(lncRNA)T342620 in patients with hepatocellular carcinoma(HCC)and the clinical value of single or combined detection with al-pha-fetoprotein(AFP)for HCC.Methods Case-control studies were conducted.A total of 69 patients with primary hepatocellular carcinoma(HCC group),32 patients with hepatitis B(hepatitis B group),20 patients with liver cirrhosis(liver cirrhosis group),30 patients after transcatheter hepatic arterial chemoembolization(TACE)for primary hepatocellular carcinoma(HCC postoperative group)and 50 healthy patients(health ex-amination group)treated in the General Hospital of Southern Theatre Command of PLA from April 2021 to May 2023 were selected as the study objects.The serum total RNA was extracted and the relative expression level of lncRNA T342620 in serum was detected by real-time quantitative PCR.Combined with the clinical di-agnosis and treatment data of patients,the correlation between its expression and pathological characteristics and serological indexes was analyzed,and the specificity and sensitivity of lncRNA T342620 alone and in com-bination with AFP in the diagnosis of HCC were analyzed by receiver operating characteristic(ROC)curve.The diagnostic efficacy was judged according to the area under the curve,and its application value in the diag-nosis of HCC was evaluated.The chi-square test was used for comparison between groups,and the Spearman method was used for correlation analysis.Results The serum expression levels of lncRNA T342620 in liver cancer group and postoperative liver cancer group were higher than those in healthy physical examination group,hepatitis B group and liver cirrhosis group,and the differences were statistically significant(P＜0.001).Clinical pathological and serological index analysis revealed that as the tumor size increased,the serum lncRNA-T342620 expression level also increased.In the HCC group,the serum lncRNA T342620 expression level was negatively correlated with albumin(ALB)and the A/G ratio(P＜0.05),while it was positively cor-related with α-L-fucosidase(AFU)and HBV-DNA(P＜0.05).In patients from the HCC postoperative group,the serum lncRNA T342620 expression level was positively correlated with total bile acid(TBA)(P＜0.05).ROC curve analysis demonstrated that when using serum lncRNA T342620 to distinguish,the sensitivi-ty and the specificity were 55.1％and 94.1％,respectively,indicating good diagnostic value.When combined with AFP detection,the sensitivity and the specificity improved to 91.3％and 91.2％,respectively,which were higher than those of individual indicators and had a superior diagnostic efficiency with area under the cuve(AUC)of 0.954 compared to AUC of AFP or lncRNA-T342620 alone(0.906,0.758),and the differ-ences were statistically significant(P＜0.05).Conclusion Serum lncRNA T342620 may be a new serological index for the auxiliary diagnosis of HCC.

This study aimed to investigate the differences in peripheral blood lymphocyte subsets among patients with different immune statuses in the early postoperative period after liver transplantation, as well as the dynamic changes during the early post-transplantation period. A retrospective study was conducted, selecting a total of 82 patients who underwent liver transplantation at the General Hospital of PLA Southern Theater Command from January, 2018 to December, 2023. Based on the patients′ postoperative immune status, they were categorized into stable group ( n=40), infection group ( n=21), and rejection group ( n=21). Peripheral blood samples of 2-3 ml were collected from patients at weeks 1 to 4 postoperatively, and flow cytometry was employed to measure the absolute values of peripheral blood lymphocyte subsets. For metric data conforming to normal distribution and homogeneity of variance, multiple group comparisons were conducted using ANOVA and Bonferroni multiple comparisons; for non-normally distributed data, the Kruskal Wallis test was used. Friedman test was used to compare different time periods within 4 weeks after liver transplantation. The results showed that there were no statistically significant differences in the absolute values of lymphocyte subsets among the three groups in the first week after liver transplantation ( P>0.05); however, significant differences were observed in the absolute values of lymphocyte subsets among the three groups in the second, third, and fourth weeks postoperatively ( P<0.05). In the second week, the rejection group showed significantly higher absolute counts of T cells, CD4 +T cells, CD8 +T cells, NK cells, and B cells compared to the infection group (585.0 vs. 199.0; 324.0 vs.113.0; 188.0 vs.56.0; 57.0 vs.11.0; 145.0 vs.65.0 cells/μl), with statistically significant differences ( Z=-3.972, P<0.001; Z=-3.590, P=0.001; Z=-3.978, P<0.001; Z=-3.072, P=0.006; Z=-2.472, P=0.040). In the third week, the rejection group showed significantly higher absolute counts of T cells, CD4 +T cells, and CD8 +T cells compared to the infection group (660.0 vs.216.0; 350.0 vs.123.0; 184.0 vs.76.0 cells/μl), with statistically significant differences ( Z=-3.019, P=0.008; Z=-3.492, P=0.001; Z=-2.845, P=0.013). In the fourth week, the rejection group showed significantly higher absolute counts of T cells, CD4 +T cells, CD8 +T cells, and B cells compared to the infection group (690.0 vs.273.0; 405.0 vs.168.0; 214.0 vs.96.0; 117.0 vs.48.0 cells/μl), with statistically significant differences ( Z=-3.379, P=0.002; Z=-3.068, P=0.006; Z=-3.007, P=0.0086; Z=-2.330, P=0.020). Within 4 weeks after liver transplantation, the absolute values of T cells, CD8 +T cells, and NK cells in the fourth week were higher than those in the first week, with statistically significant differences ( Z=-3.825, P=0.001; Z=-3.466, P=0.003; Z=-3.526, P=0.003); however, the absolute values of B cells showed an overall decreasing trend, and were significantly lower in the fourth week than in the first and second weeks, with statistically significant differences ( Z=3.705, P=0.001; Z=2.630, P=0.009). The changes in lymphocyte subset absolute values in the rejection group were more significant than those in the infection group, with T cells, CD4 +T cells, and CD8 +T cells showing significant increases in the second, third, and fourth weeks postoperatively compared with the first week, with statistically significant differences ( Z=-3.466, P=0.003; Z=-4.661, P<0.001; Z=-5.020, P<0.001; Z=-2.749, P=0.036; Z=-4.422, P<0.001; Z=-4.542, P<0.001; Z=-3.466, P=0.003; Z=-3.765, P=0.001; Z=-4.482, P<0.001); NK cell absolute values in the third and fourth weeks postoperatively were significantly higher than those in the first week, with statistically significant differences ( Z=-2.570, P=0.061; Z=-3.765, P=0.001). In summary, monitoring the differences and dynamic changes of lymphocyte subsets in patients after liver transplantation may have certain guiding significance for evaluating the immune function status of patients and adjusting treatment plans.

Objective:To construct an evaluation index system for comprehensive budget management at public hospitals and conduct empirical research for reference in evaluation of comprehensive budget management at public hospitals.Methods:From May to June 2022, based on the Implementation Measures for the Comprehensive Budget Management System of Public Hospitals and its interpretations, literature analysis, and expert interviews, a preliminary evaluation index system was developed for comprehensive budget management of public hospitals. Then the Delphi method was applied for two rounds of expert consultation, with experts invited to evaluate the importance of indexes, while the analytic hierarchy process was used to calculate the weight values of indexes. Based on such a comprehensive budget management evaluation index system, a questionnaire was developed, and tertiary public hospitals were selected based on the principle of convenient sampling. Then a questionnaire survey was conducted from June to October 2022. The questionnaire was filled out by hospital level leaders(chief accountants), finance/audit leaders, and directors of finance/audit/operation management departments from the sample hospitals with professional knowledge and rich operational management experience in budget management. The comprehensive budget management level of the sample hospital was thus evaluated based on the survey results. Results:The comprehensive budget management evaluation index system for public hospitals was composed of 2 first-level indexes, 4 second-level indexes, and 20 third-level ones. The weights for the 2 first-level indexes of target building and management orientation were both 0.500, while the weights for the 4 second-level indexes, namely strategic implementation, comprehensive coverage, performance evaluation, and adaptation matching were all 0.250. Among the third-level indexes, the weights of budget execution, system improvement, system establishment, organizational construction, and revenue and expenditure business ranked top five, with weights of 0.070, 0.069, 0.066, 0.066, and 0.064, respectively. A total of 95 hospitals were selected for questionnaire survey, and the evaluation found 46 of them with a comprehensive budget management level of " excellent" and " good" , 27 with a " moderate" level, and 22 with a " poor" and " very poor" level. Scores of the third-level indexes were between 39-94 points, while the score of 6 third-level indexes were below 60 points, namely interconnection, budget analysis, compatibility and adaptation, system improvement, participation level, and assessment application.Conclusions:The evaluation index system for comprehensive budget management at public hospitals in this study proves rational and practical, serving as a reference for the evaluation of comprehensive budget management at public hospitals and related researches.

Objective:To evaluate the role of virtual bronchoscopy intelligent system in improving the theory and operation level of bronchoscopy in pulmonary and critical care medicine (PCCM) teaching for standardized training specialists.Methods:A total of 50 PCCM physicians who had participated in virtual bronchoscopy training in Xijing Hospital, Air Force Medical University from 2018 to 2021 were selected as research subjects. In this study, self-controlled method was adopted to evaluate the change of assessment indicators after 1 week and 2 weeks of training. Questionnaire survey was also used to evaluate the training effect. SPSS 23.0 software was used for paired t-test and Chi-square test. Results:All the 50 PCCM physicians successfully completed the training of virtual bronchoscopy operation. The theoretical score was significantly improved after the training [(80.0±5.2) points vs. (92.4±3.8) points]. The basic operation time [(1 050.9±103.3) s vs. (386.4±47.7) s], and the number of hitting the bronchial wall [(88.3±12.7) times vs. (27.0±5.3) times] were significantly reduced. The recovery rate of alveolar lavage fluid [(27.6±7.4)% vs. (58.0±8.2)%] and the positive rate of biopsy [(19.2±13.1)% vs. (86.8±10.8)%] were significantly increased. The learning curve of the final score indicated that the score improved more rapidly in the first week of training, and the score improved more slowly in the second week of training. Questionnaires before and after the training indicated that virtual intelligent training could significantly improve the confidence and proficiency of students in bronchoscopy.Conclusion:Through the systematic training of virtual bronchoscopy intelligent system, the PCCM physicians have significantly improved their theoretical knowledge and operational proficiency. Therefore, the virtual bronchoscopy training system has practical significance for improving the overall training effect of clinical bronchoscopy for PCCM trainees, which is worthy of promotion.

ObjectiveTo investigate the prevalence of overweight or obesity in community patients with schizophrenia in Shanghai and to explore the related factors. MethodsStratified cluster sampling method was used and the general condition， physical examination and laboratory examination data of patients with schizophrenia who voluntarily participated in 2020 free health examination of National Basic Public Health Service were analyzed. ResultsA total of 3 200 patients were included into the study ，and the prevalence of overweight and obesity was 36.75% and 17.19%， respectively. Multivariate logistic regression analysis indicated that age between 40 and 60 （OR=1.333， 95%CI： 1.030‒1.724）， intake of first-generation antipsychotics （OR=1.413， 95%CI： 1.112‒1.796）， intake of second-generation antipsychotics （OR=1.573， 95%CI： 1.288‒1.921）， high-normal blood pressure （OR=1.549， 95%CI： 1.245‒1.927）， high-abnormal blood pressure （OR=2.824， 95%CI： 2.204‒3.619）， elevated ALT （OR=1.874， 95%CI： 1.386‒2.535）， elevated FBG （OR=1.270， 95%CI： 1.066‒1.513）， and elevated TG （OR=1.652， 95%CI： 1.335‒2.044） were the related factors that associated overweight or obesity in patients with schizophrenia. ConclusionOverweight and obesity are highly prevalent among community patients with schizophrenia in Shanghai. Age between 40 and 60， taking first-generation and second-generation antipsychotics， blood pressure higher than 120/80 mmHg， elevated ALT， elevated FBG， and elevated TG are associated with overweight or obesity in patients with schizophrenia. To provide personalized health guidance， medical staff in primary health care institutions should pay more attention to high-risk groups of overweight and obesity in schizophrenia patients at annual physical examination.

Internal auditing for infrastructure projects carried at multi-campuses of a hospital to support hospital strategic growth, is a crucial means in raising the business performance and capacity. A public hospital made a research-based audit to examine infrastructure projects across multi-campuses since 2021. At the pre-trial stage, the audit plan was created in a " two-coordination" manner to define the scope of authority and responsibility of audit objectives; at the in-trial stage, audit priorities were focused on in advance through intelligent early warning, and full-course audit guidance and quality control was made through online real-time audit operation system; at the post-trial stage, efforts were focused on resolving problems, summarizing audit findings. The authors introduced the practice of the hospital and further explained the specific application methods and achievements through case analysis, providing reference for internal audit of infrastructure projects in multi-campus hospitals, for reference in likewise internal auditing.

Objective : To study the guidance effects of fibroblast growth factor 3 ( FGF3) on the prethalamic γ⁃aminobutyric acid (GABA) inhibitory axons, and to explore the effect of FGF3 on the formation of thalamic axonal network. Methods : Expression and localization of FGF3 and prethalamic GABA marker gene in chicken embryonic diencephalon were detected by immunofluorescence. Early orientation of GABA axons was tracked by DiI. Three⁃dimensional gel co⁃culture experiment was carried out to investigate guidance effects of FGF3 on early prethalamic GABA inhibitory axons. Results : Prethalamic GABA cells were adjacent to the FGF3 + hypothalamas, located above the hypothalamus. DiI tracing experiments revealed that prethalamic GABA inhibitory axons had already extended into the thalamus at E6. Compared with the blank control group, FGF3 not only significantly promoted the growth of prethalamic GABA inhibitory nerve fibers in the prethalamus, but also repelled the newborn prethalamic axons to the dorsal thalamus. The number of prethalamic axons was significantly less in proximal section (towards FGF3 beads) than that in distal section (away from FGF3 beads) (P < 0. 01) . Moreover, the guidance effects of FGF3 on prethalamic axons could be blocked by the FGF pathway inhibitor SU5402. Conclusion FGF3, an axon guidance molecule expressed in hypothalamus, exerts guidance effects on the pathway selection of adjacent prethalamic GABA inhibitory nerve fibers.

Objective: To investigates the prevalence of depression and anxiety among middle school students at different times, and to provide a reference for mental health promotion among adolescents. Methods: A total of 1 505 middle school students, selected from Chongqing in 2021 by using multi stage stratified random sampling method, were surveyed by using the Center for Epidemiologic Studies Depression Scale(CSE-D) and Zung Self Rating Anxiety Scale (SAS). Results: At the beginning of the semester, 434(27.6%) and 601 students( 38.2 %) reported depressive and anxiety symptoms,respectively. While at the end of the semester showed that 463 cases (30.8%) were prone to depression, and 653 cases ( 43.4 %) reported depressive and anxiety symptoms,respectively. The detection rate of depressive symptoms at the end of the semester was significantly higher than that at the beginning of semester. (43.4%, 38.2 %, χ 2=8.55, P <0.05). Depressive of female students at the end of the semester( 52.8 %) was higher than that at the beginning of the semester(46.3%)( χ 2=6.19, P <0.05) The detection rate of anxiety symptoms in senior high school students at the end of the semester(44.9%) was significantly higher than that of at the beginning of the semester(28.6%) ( χ 2= 43.33 , P <0.01). No significant difference in anxiety symptoms boys and junior high school students between the beginning and the end of the semester ( χ 2=2.34, 0.71, P >0.05). Conclusion Substantial changes are observed in anxiety symptoms among female middle school students and depressive and anxiety symptoms among high school students in different periods of a semester. When investigating depression and anxiety of middle school students, time effect should be considered.

ObjectiveTo apply ultrasonography to quantitatively evaluate the structure and biomechanical properties of gastrocnemius muscle in children with spastic cerebral palsy. MethodsFrom December, 2020 to December, 2021, 36 children with spastic diplegia or hemiplegia were selected as experimental group, and other 30 healthy children matched age and gender were as control group during the same period. All the subjects were measured muscle thickness (MT), muscle fiber length (FL), pinnate angle (PA) and shear wave velocity (SWV) with two-dimensional ultrasound imaging and shear wave elastography on the medial gastrocnemius of the affected side (hemiplegia), more serious side (diplegia) or random side (control group), while the gastrocnemius muscle tone and gross motor function of the experimental group were assessed with modified Ashworth Scale (MAS) and Gross Motor Function Measure (GMFM). ResultsMT and FL were less in the experimental group than in the control group (|t| > 3.937, P < 0.001), while PA and SWV were more (|t| > 6.105, P < 0.001). MT and FL positively correlated to GMFM score (r > 0.391, P < 0.05), while SWV positively correlated to MAS score (r = 0.734, P < 0.001). ConclusionUltrasonography can be used to quantitatively evaluate the structure and stiffness of gastrocnemius muscle for children with spastic cerebral palsy.
