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.

Porcine reproductive and respiratory syndrome (PRRS) is a highly contagious disease caused by porcine reproductive and respiratory syndrome virus (PRRSV), which causes great economic losses. At the moment, no effective neutralizing antibody is available for scientific research and treatment. Therefore, developing a method for screening the neutralizing monoclonal antibodies is of great significance for the prevention and treatment of PRRSV and the screening of antigen sites. Monoclonal antibodies have been widely used in the treatment and diagnosis of many human and animal diseases. Therefore, screening effective neutralizing antibodies for different pathogens is an urgent task. Among the methods for monoclonal antibody screening, B cell immortalization is an effective method to obtain neutralizing monoclonal antibody. Specifically, in this study, the bcl-6 and bcl-xl genes were connected by f2a and then the yielded product was ligated to a vector for retrovirus packaging. The swine lymphocytes immunized with PRRSV were infected the yielded mature viruses and cultured in the complete medium containing CD40L and IL21 cytokines. Then, CD21 was used as the marker to screen B cells with the magnetic bead method. Finally, monoclonal B cells were obtained and the secretion of antibodies was tested. The results showed that the plasmid, either being transfected alone or with the packaged plasmids, could be expressed, and that the packaged retrovirus could infect the cells. Moreover, the infected lymphocytes secreted antibodies, so did the screened B cells. Therefore, the method for screening monoclonal antibody against PRRSV was successfully established.

Objective:To investigate the protective effect of nicotinamide phosphoribosyltransferase (NAMPT) on abdominal aortic aneurysm by delaying the senescence of aortic vascular smooth muscle cells (VSMC).Methods:The primary VSMC cells from normal and patients with abdominal aortic aneurysm were cultured by tissue adherence method. Cells were divided into normal human-derived VSMC group (Ctrl-VSMC group), abdominal aortic aneurysm patient-derived VSMC group (AAA-VSMC group), and angiotensinⅡ(AngⅡ) in vitro abdominal aortic aneurysm model group (AngⅡ-VSMC group, 100 nmol/L AngⅡ treated normal human-derived VSMC for 48 hours), AngⅡ+P7C3 group and AAA+P7C3 group after NAMPT agonist P7C3 intervention (adding 5 μmol/L P7C3 on the basis of AngⅡ-VSMC group and AAA-VSMC group, respectively). Immunofluorescence staining was used to identify VSMC; cell proliferation-associated antigen Ki67 staining was used to detect cell proliferation; senescence associated β-galactosidase (SA-β-gal) staining was used to detect cell senescence in each group; Western blotting was used to detect the protein expression levels of senescence-related proteins p21, p16 and NAMPT in each group. Results:Compared with the Ctrl-VSMC group, the positive rate of SA-β-gal staining and the expression levels of senescence-related proteins p21 and p16 in the AAA-VSMC group and AngⅡ-VSMC group were significantly increased [SA-β-gal staining positive rate: (74.1±4.4)%, (68.6±5.5)% vs. (36.8±10.3)%, p21/GAPDH: 0.61±0.07, 0.51±0.03 vs. 0.31±0.03, p16/GAPDH: 0.77±0.03, 0.72±0.06 vs. 0.33±0.26, all P < 0.01]. However, the expression of NAMPT was significantly decreased (NAMPT/GAPDH: 0.88±0.07, 0.79±0.14 vs. 1.29±0.02, both P < 0.01). Compared with the AngⅡ-VSMC group, the positive rate of SA-β-gal staining and the expressions levels of senescence-related proteins p21 and p16 in the AngⅡ+P7C3 group were significantly lower [SA-β-gal staining positive rate: (49.1±3.2)% vs. (68.6±5.5)%, p21/GAPDH: 0.35±0.06 vs. 0.51±0.03, p16/GAPDH: 0.47±0.08 vs. 0.72±0.06, all P < 0.05], while the expression of NAMPT was significantly increased (NAMPT/GAPDH: 1.15±0.06 vs. 0.79±0.14, P < 0.01). Compared with the AAA-VSMC group, the positive rate of SA-β-gal staining and the expression levels of senescence-related proteins p21 and p16 in the AAA+P7C3 group were significantly lower [SA-β-gal staining positive rate: (54.1±6.0)% vs. (74.1±4.4)%, p21/GAPDH: 0.38±0.02 vs. 0.61±0.07, p16/GAPDH: 0.50±0.13 vs. 0.77±0.03, all P < 0.05], but the expression of NAMPT was significantly increased (NAMPT/GAPDH: 1.25±0.28 vs. 0.88±0.07, P < 0.01). Conclusion:NAMPT agonist P7C3 can delay the senescence of VSMC and play a protective role in abdominal aortic aneurysm.
