The factors of doctors'prescription for essential medicines are work experience,average monthly income, policy awareness, recognition, training willingness, training times, hospital support, medication preferences,and drug marketing.Conclusion The prescription rate of essential medicines in the sampled hospitals is low,and the targeted comprehensive intervention measures should be taken to promote prescription rate of essential medicines in county hospitals.

Objective:Using the method-point-factor to construct a system of evaluation indexes for clinician positions in county-level public hospitals to assess the relative value of clinician positions in county-level public hospitals in Anhui province.Methods:Questionnaire survey was used for a questionnaire survey of 12 county-level public hospitals in northern Anhui, central Anhui and southern Anhui in the province from July to August 2019. The content of the questionnaire survey mainly includes such doctor′s basic information as gender, age, and department, as well as the doctor′s score on the four dimensions of " post qualification, skills, risks and responsibilities, work intensity and environment" . In this study, Excel 2010 and SPSS 16.0 were used to perform descriptive statistical analysis on the collected data.Results:In this study, a job evaluation system for doctors in county-level public hospitals was established, covering 4 level-1 indicators, 10 level-2 indicators, and 37 level-3 indicators. Among the 1 895 clinical doctors participating in the survey in 12 county-level public hospitals, the average score of doctor′s job evaluation was 768.4 points, of which the neurosurgeons had the highest average score of 800.90 points and endocrinologists had the lowest average score of 735.40 points. There were differences in the overall score rate in the four dimensions of job evaluation, in the order of " risk and responsibility, work intensity and environment, skills, job qualification" (80.09%>79.49%>79.24%>66.72%).Conclusions:The results and grades of clinical doctors′ job evaluation were reasonable. The overall trend of the scores was in line with the job characteristics of doctors, and provided a theoretical basis for improving the internal performance salary distribution system of county-level public hospitals.

Objective:To form the workload relative value of 10 general surgery projects in Anhui province based on the theoretical framework of resource-based relative value scale(RBRVS).Methods:Cluster sampling was used to identify the 12 county-level public hospitals surveyed from July to August 2019; Expert consultation method was used to select the benchmark project of general surgery and the measured projects; Magnitude estimation was used by doctors surveyed to find the relative evaluation of the surgeries selected, and RBRVS principle was used to find surgeon workload relative value of the 10 surgeries; Pearson correlation analysis was used to analyze the relationship between the charging price of surgeries and the relative value of surgeons′ workload in Anhui province.Results:The study found the time consumption, work intensity relative value and surgeon work load relative value of 10 general surgeries; The relative value of the current surgical item price was positively correlated with the relative value of the doctor′s workload, and the correlation coefficient was r=0.928, P<0.01(bilateral). But in some surgeries, the pricing fails to represent the relative value of the workload. Conclusions:Based on RBRVS theory, 10 localized relative value scales of general surgeons′ workload were developed via empirical studies from such dimensions as time consumption, mental labor, physical labor and risk stress; Pearson′s correlation analysis found part of the pricing in general surgeries as groundless.

ObjectiveTo encourage development of county-level hospitals by building a performance appraisal indicator system for such institutions. Methods Using the PATH model ( a performance appraisal tool for hospital ) quality improvement, an appraisal system was built for such institutions. Centering on patients, this system encompassed such dimensions as public benefits, quality of care and safety, staff and hospital development. Results This system consisted of six level-1 indicators, 21 level-2 indicators and 70 level-3 indicators, each given due weight. Conclusions This indicator system centers on patients, follows guidance of public benefits, and aims at continuous quality improvement, making it an effective in evaluating hospital performance and providing reference for the decision-makers to promote and adjust medical reform policies.

Ventilators are currently the most commonly used auxiliary mechanical ventilation equipment in clinical practice, and play an important role in the treatment of hypoxemia. Ventilator-associated pneumonia (VAP) is a special type of pulmonary parenchymal inflammation of nosocomial infection in patients with mechanical ventilation, which leads the increase of mortality and affects the prognosis of patients. The non-standard management of ventilator pipeline joints and the aerosol formed by bacterial condensate splashed from ventilator pipeline pollute the air, resulting in cross infection, which are the important reasons for VAP. The existing ventilator pipeline joint cap can achieve the effect of preventing pollution, but the clinical application compliance is not high. Based on the above factors, teachers, students and medical staff of the School of Public Health and Management, Guangxi University of Chinese Medicine and other units have designed a device for preventing pollution and air pollution of the ventilator pipeline joint, and obtained the national utility model patent of China (ZL 2020 2 1361981.X). The device is composed of a model lung, a mask body, a suspension part and a beam mouth part, etc. The use method is simple, and can be applied to the pollution avoidance of invasive ventilator and non-invasive ventilator pipeline joints, to reduce the occurrence of VAP in patients and the occupational exposure of medical staff.

Objective:To determine the expression of Brahma-related gene 1 (BRG1) in cutaneous squamous cell carcinoma (cSCC) tissues and cells, and to investigate molecular mechanisms underlying the regulatory effect of its interaction with activating transcription factor 2 (ATF2) on the proliferation, migration and invasion of cSCC cells.Methods:From 2015 to 2021, 66 paraffin-embedded actinic keratosis (AK) tissue samples and 80 paraffin-embedded cSCC (including squamous cell carcinoma in situ) tissue samples were collected from the Department of Dermatology, Affiliated Hospital 2 of Nantong University, and the diagnoses of all the cases were confirmed histopathologically; at the same time, 35 paraffin-embedded normal skin tissue samples obtained by cosmetic surgery served as normal control group. Immunohistochemical staining was performed to determine the BRG1 expression in cSCC, AK, and normal skin tissues, and correlations between BRG1 expression and clinicopathological parameters of cSCC patients were analyzed. Fresh tissue samples were collected from 12 cSCC patients and 12 healthy controls, and cSCC cell lines A431 and Scl-1 and a human immortalized keratinocyte cell line HaCaT were routinely cultured; real-time fluorescence-based quantitative PCR (qRT-PCR) was performed to determine the mRNA expression of BRG1 in tissues and cells, and co-immunoprecipitation assay and cellular immunofluorescence staining were conducted to analyze the interaction between BRG1 and ATF2. The expression of BRG1 (BRG1 siRNA1 - 5 groups) and ATF2 (ATF2-shRNA group) in A431 and Scl-1 cells was knocked down by RNA interference, and cells transfected with negative control siRNA or shNC served as controls (control siRNA group and shNC group, respectively), cell counting kit-8 (CCK8) assay, colony formation assay, cell scratch assay, and Transwell assay were conducted to evaluate effects of knocking down BRG1 and ATF2 on the proliferation, migration, and invasion of cSCC cells. Comparisons of measurement data among multiple groups were conducted using one-way analysis of variance, and multiple comparisons were conducted using Dunnett- t test. Results:Immunohistochemical staining showed that the expression intensity of BRG1 protein was significantly lower in the cSCC and AK tissues than in the normal skin tissues ( χ2 = 44.40, P < 0.001). qRT-PCR showed that the mRNA expression level of BRG1 was significantly lower in the cSCC tissues (1.345 ± 0.956) than in the normal skin tissues (2.499 ± 1.501, t = 2.25, P = 0.035), and also significantly lower in A431 and Scl-1 cells (0.041 ± 0.002, 0.026 ± 0.003, respectively) than in HaCaT cells (0.135 ± 0.033, t = 4.95, 5.73, P = 0.008, 0.005, respectively). The low expression of BRG1 was associated with tumors at sun-exposed sites ( P = 0.041), low tumor differentiation ( P = 0.001), and high Broder′s grade ( P < 0.001) in the cSCC patients. In both A431 cells and Scl-1 cells, the BRG1 siRNA1 group and BRG1 siRNA2 group showed significantly increased numbers of cell colonies, migratory cells and invasive cells, as well as cell migration rates compared with the control siRNA group (all P < 0.05). Co-immunoprecipitation assay showed that BRG1 protein could bind to ATF2 protein in A431 and Scl-1 cells, and immunofluorescence staining showed that the two proteins were co-localized; compared with the control siRNA group, the BRG1 siRNA1 group (both A431 and Scl-1 cells) and BRG1 siRNA2 group (A431 cells) both showed increased phosphorylation and activation of ATF2 (all P < 0.05) ; in both A431 cells and Scl-1 cells, the shATF2 group showed significantly decreased numbers of cell colonies (both P = 0.001), cellular proliferative activity at 24 - 96 hours (all P < 0.001), and numbers of migratory cells and invasive cells compared with the shNC group (all P ≤ 0.001) . Conclusion:BRG1 was lowly expressed in the cSCC and AK tissues, and could inhibit the proliferation, migration, and invasion of cSCC cells; ATF2 could promote the proliferation, migration, and invasion of cSCC cells; BRG1 may exert an anti-tumor effect by interacting with ATF2 protein and inhibiting phosphorylation-dependent activation of ATF2.

Objective:To assess the effects of noninvasive positive pressure ventilation on premature infants' cardiac function using Tei index combined with corrected QT dispersion (QTcd) and B- type natriuretic peptide (BNP).Methods:This prospective study involved premature infants from 28 to 32 weeks of gestational age diagnosed with respiratory distress syndrome (RDS) and treated with noninvasive positive pressure ventilation in the Neonatal Intensive Care Unit of Xuzhou Central Hospital from December 2017 to December 2020. According to the mean airway pressure (MAP) during noninvasive positive pressure ventilation, the patients were divided into the low-pressure group (≤6 cmH 2O, 1 cmH 2O=0.098 kPa), medium-pressure group (>6-<9 cmH 2O), and high-pressure group (≥9 cmH 2O). The right ventricular Tei index, QTcd, and blood BNP were monitored during the first 2 h of noninvasive positive pressure ventilation and 12 h after continuous ventilation with stable MAP. Chi-square test, one-way analysis of variance, paired t-test, and Pearson product-moment correlation coefficient were adopted for statistical analysis. Results:Totally 178 premature infants were enrolled, including 75 in the low-pressure, 62 in the medium-pressure, and 41 in the high-pressure group. After continuous ventilation with stable MAP for 12 h, the right ventricle Tei index and QTcd in the high-pressure group were higher than those in the medium- and low-pressure group [Tei index: (0.38±0.05) vs (0.33±0.04) and (0.33±0.04), F=29.18; QTcd: (27.6±4.2) vs (22.8±4.4) and (22.2±4.2) ms, F=23.26, all P<0.001], and the comparison between the medium- and the low-pressure group did not differ significantly. No significant difference was observed in blood BNP levels among the three groups ( F=1.33, P=0.267). The right ventricle Tei index and QTcd increased in the high-pressure group after continuous ventilation with stable MAP for 12 h as compared with those within the first 2 h of noninvasive positive pressure ventilation [Tei index: (0.38±0.05) vs (0.34±0.04), t=－6.61; QTcd: (27.6±4.2) vs (23.4±4.4) ms, t=－5.06, all P<0.001]. However, the figures did not change significantly in the medium- or the low-pressure group (all P>0.05). There were no significant changes in blood BNP in the three groups (all P>0.05). The right ventricle Tei index and QTcd were moderately positively correlated with MAP ( r=0.56 and 0.50, both P<0.001). Conclusions:For the premature infants with RDS, noninvasive positive pressure ventilation has no significant effect on the cardiac function when MAP is less than 9 cmH 2O, but would have a certain effect on the right ventricular function when used at higher pressure (MAP≥9 cmH 2O) and for longer time (>12 h).
