ObjectiveTo explore the expression of N-cadherin and β-catenin mRNA in human brainstem and supratentorial gliomas. MethodsN-cadherin and β-catenin mRNA expression in 18 cases of brainstem gliomas and 18 cases of supratentorial gliomas tissues were detected with PT-PCR. Resultsβ-catenin mRNA expression was more in human brainstem gliomas than in supratentorial gliomas （t=2.255,P<0.05）, but was not significantly different of N-cadherin mRNA (P＞0.05). The expression of N-cadherin mRNA in human brainstem gliomas of grades Ⅰ～Ⅱ were less than those in human gliomas of grades Ⅲ～Ⅳ (t=2.711，P<0.05), but was not of β-catenin mRNA (P＞0.05). N-cadherin mRNA expression was positively correlated with the β-catenin mRNA expression in either brainstem gliomas or supratentorial gliomas （r=0.480，r=0.809 respectively, P<0.05）. ConclusionThe over expressions of N-cadherin and β-catenin may play an important role in the invasion and malignant progress of human brainstem gliomas.

Objective To observe the effect of aralia saponins on the expression of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) in the kidney of diabetic nephropathy mice.Methods After 10 days of adaptive feeding,90 clean Kunming mice were randomly divided into the normal group (n =10) and 5 model groups (model group,positive drug benazepril intervention group,aralia saponins low,middle and high doses treatment groups).Excepted the normal group,the kidney damage model of type 2 diabetes mellitus in mice was induced by high-fat and high-sugar diet for one month plus disposable streptozotocin (STZ).The model was successfully constructed and killed after 6 weeks of treatment.A total of 25 mice failed to establish the model.And totally 55 mice were randomly divided into 5 groups with 11 mice in each group.The serum changes of blood urea nitrogen (BUN),serum creatinine (SCr),insulin,inflammatory factors interleukin-1α (IL-1α),interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in each group were detected.The expression of vascular endothelial growth factor and MMP-9 protein in renal tissue were detected by immunohistochemistry and Western blot.Results Compared with the normal group,the levels of blood glucose,insulin,BUN,SCr,IL-1α,IL-6 and TNF-α in the model group were significantly increased (P ＜ 0.05).The above indexes were decreased in positive drug group and aralia saponins treatment groups.The contents of insulin,BUN and SCr in the high dose of aralia saponins group were significantly lower than those parameters in benazepril group (P ＜ 0.05).In addition,the contents of blood glucose,IL-1α,IL-6 and TNF-α in the three dose aralia saponins groups were significantly lower than those parameters in the benazepril group (P ＜ 0.05).Compared with the normal group,the expression level of VEGF protein in the model group was significantly higher (P ＜ 0.05),and the expression level of MMP-9 protein was significantly lower (P ＜ 0.05).Compared with the model group,both benazepril and aralia saponins can reduce VEGF (P ＜ 0.05),increase MMP-9 (P ＜ 0.05).In addition for VEGF and MMP-9,the high dose of aralia saponins group and benazepril group was basically same.Conclusions Aralia saponins can significantly reduce blood glucose,insulin and serum inflammatory factors,while downregnlate VEGF and increase MMP-9 protein levels,thereby protecting the kidneys of diabetic nephropathy mice.

Objective:To construct an evaluation index system for the reform of public hospital salary system and conduct empirical research, for reference in deepening the reform of public hospital salary system.Methods:Based on the building blocks of health systems and the Guiding Opinions on Pilot Work of Public Hospital Salary System Reform (Human Resources and Social Security Ministry 〔2017〕 No. 10), a preliminary index system was constructed. And the expert consultation method was used to determine the evaluation index system for public hospital salary system reform. The authors selected representative hospitals in Chaoyang district of Beijing with reform experiences of such salary system, and applied this index system for empirical research. Objective indexes were extracted from the hospital information system, which were used to evaluate relevant data before the reform (from 2016 to 2017) and after the reform (from 2018 to 2019); a questionnaire was customized based on the subjective indexes in the index system, which was used for a questionnaire survey on hospital staff, outpatient patients, and inpatients. A descriptive analysis was made on such indexes as hospital revenue and expenditure, medical expenses, salary levels, and satisfaction. The comparison of relevant data before and after the reform was conducted using one-way ANOVA. Results:This study constructed a public hospital salary system reform evaluation system, comprising 4 first-level indexes, 8 second-level indexes, and 38 third-level indexes. second-level indexes were salary level and structure, salary governance and information construction, health manpower and service provision, medical products and technology. There were 28 objective indexes and 10 subjective ones. The evaluation results of 4 representative public hospitals showed that the proportion of labor costs, hygiene materials income, treatment income, nursing income, and physician service fees to the total income increased as compared to that before the reform, with statistical significance ( P<0.05); The average medical expenses of discharged patients and the proportion of drug income (excluding traditional Chinese medicine slices) to total income decreased compared to that before the reform, and the difference was statistically significant ( P<0.05); The difference between the average medical expenses per outpatient visit and the proportion of surgical income to total income was not statistically significant ( P>0.05). There was no statistically significant difference in salary levels among employees of different genders, seniority, and educational backgrounds ( P>0.05). On the other hand, there was a statistically significant difference in salary levels among employees of different ages, majors, professional and technical titles, and employment types ( P<0.05). The actual salary of 636 employee was only 56.26% of the expected salary, and their total score of salary satisfaction was (3.33 ± 0.86) points. The scores of public service motivation, medical service quality, and job satisfaction were (3.52 ± 0.78) points, (3.91 ± 0.77) points, and (3.72 ± 0.65) points, respectively. The satisfaction scores of outpatient and inpatient patients were (4.64 ± 0.23) and (4.82 ± 0.45), respectively. Conclusions:The evaluation system for the reform of the salary system in public hospitals constructed in this study can comprehensively evaluate the effectiveness of hospital reform from a multidimensional perspective, combining quantitative and qualitative, subjective and objective aspects. It proves scientific and practical.

Objective To study the effect of aralia total saponins on renal function of type 2 diabetic mice, and its effect on the Bax and Bcl-2 protein in renal tissues, in order to provide some references for the development of aralia total saponins. Methods The mice were divided into the normal group, model group, positive control group, low, medium and high dose aralia total saponins group by random number method. Except the normal group, the others were received with high-fat diet for one month+one-time large dose of streptozotocin (STZ) to induce type 2 diabetic model, and then the mice in the normal group and the model group were intragastrically administered with the same volume of normal saline, and the mice in the positive control group was given 1 mg/kg of benazepril solution, and the low, medium and high dose groups were given 30, 60, 120 mg/kg aralia total saponins. The body weight of 1 ml/kg mice was intragastrically administered once a day. After treatment for 6 weeks they were sacrificed, and the serum insulin, and SOD and MDA levels were measured, the urine creatinine (Cr), urea nitrogen (UN), and uric acid (UA) levels were also measured. The immunohistochemistry and Western blot were used to detect the Bax and Bcl-2 protein expression in kidney tissues. Results Compared with the model group, the blood glucose and insulin resistance index in the low, medium and high doses aralia total saponins group were significantly decreased (P<0.05); the levels of urine UN, Cr and UA significantly decreased (P<0.05); The serum SOD level increased and the MDA level significantly decreased (P<0.05). The average gray value of Bcl-2 increased (92.26 ± 11.36, 107.17 ± 9.26, 132.65 ± 8.45 vs. 56.42 ± 16.24) in kidney tissue. The average gray value of Bax (152.62 ± 9.86, 124.48 ± 10.36, 92.29 ± 10.10 vs. 171.38 ± 15.18) significantly decreased ( P<0.05); Bax protein (0.81 ± 0.06, 0.75 ± 0.07, 0.52 ± 0.09 vs. 2.02 ± 0.09) significantly decreased, but Bcl-2 protein (0.92 ± 0.08, 0.94 ± 0.12, 1.27 ± 0.07 vs. 0.30 ± 0.09) significantly increased (P<0.05). Conclusions The aralia total saponins can reduce blood sugar levels, meanwhile improve renal function in type 2 diabetic mice. The mechanism may be may be that aralia total saponins could improve the antioxidant capacity and inhibition of renal cell apoptosis.
