Objective: To evaluate the compensation level of the Urban Employee Basic Medical Insurance ( UEBMI ) and Urban Resident Basic Medical Insurance ( URBMI ) in Jiangsu province . Methods: Take catastrophic health expense as the bottom line of compensation ratio for the basic medical insurance, the benefit of hospitalization expenses of those joining the insurance as the actual line of compensation ratio, and quartile division was used to comparatively analyze the differences between the bottom line of compensation ratio and the actual line of compensation ratio. Results: Take 10%as the critical value of catastrophic health expense, the actual line of compensation level is higher than the bottom line of compensation level in UEBMI, and there is reverse in URBMI. Conclusion: In some extent, the compensation level of UEBMI has relieved the economic burden of the poor jointed group because of sickness, while limited compensation level of UEBMI is in need of further improvement.

To discover factors affecting the inpatient’ actual reimbursement rate of urban resident basic medical insurance ( URBMI ) . Methods: Using the method of correlation analysis and multiple stepwise regression modeling to identify the influencing factors. Results: The per capita funding criteria, rate of inpatient out of pocket payment over resident annual per capita disposable income and per capita hospitalization rate have significant effect on the actual reimbursement rate of URBMI. Conclusion: It is needed to establish a sustainable steady financing mechanisms for URBMI, improve the evaluation system of reimbursement policy and gradually raise the level of actual reimbursement.

Objective:To investigate the nutritional status of patients with locally advanced nasopharyngeal carcinoma (NPC) and its relationship with prognosis. Methods: From August 2015 to March 2018, 53 patients with locally advanced NPC hospitalized for treatment at the Department of Radiotherapy at Hubei Cancer Hospital, Wuhan, China, were enrolled in this study. The patient-generated subjective global assessment (PG-SGA), anthropometry measurements, hematological indexes, and side-effects of radiation and chemotherapy were used to evaluate the nutritional status. Survival and its influencing factors were further analyzed using the Kaplan-Meier estimator and a Cox proportional hazards regression model. Results: 94.3% of the locally advanced NPC patients lost weight. The average weight loss was 6.89 ± 0.54 kg. Of those NPC patients who lost weight, 50.94 % had more than 10% weight loss. According to the PG-SGA score, 84.9% of the NPC patients had severe malnutrition (PG-SGA≥9). A highly negative correlation was observed among lymphocyte count (TLC), red blood cell (RBC), hemoglobin (Hb) level, albumin (ALB) level, and PG-SGA scores (all P<0.05). A highly positive correlation was observed among oral mucositis, difficulty swallowing or pain, anorexia, rate of weight loss, and PG-SGA scores (all P<0.05). Univariate and multivariate analyses showed that a high TNM stage and more than 10% weight loss during treatment were associated with an unfavorable prognosis. A high level of white blood cells (WBC), within the normal range, was associated with a better survival rate (All P<0.05). Conclusions: Patients with locally advanced NPC had a high incidence of malnutrition in this study. PG-SGA combined with anthropometry measurements, hematological indexes, and side-effects of radiation and chemotherapy can help evaluate the nutritional status of patients with NPC more comprehensively. A high TNM stage, more than 10% weight loss during treatment, and high WBC counts were independently associated with prognosis and survival among patients with locally advanced NPC.

AIM:To investigate the expression of poly (ADP-ribose) polymerase-1 (PARP-1) in the epithelial ovarian cancer ( EOC) and its relationship with epithelial-mesenchymal transition ( EMT) .METHODS:The expression of PARP-1, E-cadherin, vimentin and Snail was detected in the EOC and benign ovarian tumor tissues by immunohistochemi -cal method and real-time PCR.The expression of PARP-1, E-cadherin, vimentin and Snail proteins in the SKOV3 cells treated with efficient PARP-1 inhibitor PJ34 was determined by Western blotting .RESULTS:The positive expression rates of PARP-1, vimentin and Snail were significantly higher in the EOC than that in the benign ovarian tumor tissues , whereas the positive expression rate of E-cadherin was the opposite (P<0.05).The expression of PARP-1, E-cadherin, vimentin and Snail in the EOC was associated with the histological grade , clinical stage and lymphatic metastasis (P<0.05), but no relationship with age and pathological types was observed .The expression of E-cadherin in the EOC was negatively co-related to that of PARP-1.In contrast, the expression of vimentin and Snail in the EOC was positively co-related to that of PARP-1.The relative mRNA expression of PARP-1, vimentin and Snail in the EOC was significantly higher than that in the benign ovarian tumor tissues ( P<0.05) , while the mRNA expression of E-cadherin in the EOC was remarkably lower than that in the benign ovarian tumor tissues (P<0.05).The protein expression of PARP-1, vimentin and Snail in the SKOV3 cells was significantly decreased (P<0.05), while E-cadherin protein was increased after treated with PJ 34(P<0.05). CONCLUSION:PARP-1 may contribute to the onset of EMT in the EOC by regulating the expression of E -cadherin, vim-entin and Snail.The role of PARP-1, which is relevant to EMT, might be important in the development of ovarian cancer .

Effect of new calcium antagonist m-nisoldipine (m-Nis) on MCT-induced PH in rats and its mechanisms were investigated. Rats were injected with a single doxe(60mg·kg-1)of MCT subcutaneously to induce PH. Pulmonary haemedynamic measurement and lung tissue morphological investigations were undertaken. The MDA production and SOD activity in the serum were tested. PCNA,ERK1 and p-ERK expressions were analyzed by Western blotting. The expressions of 5-HT and PCNA were observed with immunohistochemistry. Results suggested that the PAP, right ventricular index and the degree of muscularization of small pulmonary artery were elevated markedly in MCT group, which was attenuated by m-Nis treatment. A significant reduction in MDA production and an increase in the SOD activity in the serum were also observed in all three m-Nis groups. The number of PCNA and 5-HT positive smooth muscle cells increased significantly in MCT group, and m-Nis treatment attenuated the expression obviously. Western blotting results suggested that the protein expression of PCNA and the ratio of p-ERK/ERK1 increased markedly in MCT group and decreased by m-Nis. In conclusion, m-Nis protected against MCT-induced PH by decreasing PAP, right ventricular index, PAMSCs proliferation and pulmonary artery remodelling, which may be related to the reduction of 5-HT and the suppression of the ERK/MAPK signal pathway.
