  • Expression of aquaporin-1 in rat model of carrageenan-induced pleural effusion

    Objective To investigate the expression of aquaporin-1(AQP-1) on pleura in rats with carrageenan-induced pleural effusion and explore the role of AQP-1 in effusion formation.Methods Fifty-six healthy Wistar rats were randomly divided into a normal control group and 6 pleuritis groups(6,12,24,36,48 and 72 h groups respectively).The rat model of inflammatory pleurisy was induced by injecting l-Carrageenan into the pleural cavity.The expression of AQP-1 on pleura was detected with immunohistochemistry.The mRNA and protein expression of AQP-1 on visceral pleura and parietal pleura were measured by RT-PCR and Western blot assay respectively.The volume of pleural effusions were measured.Results The volume of pleural effusion was 2.10±0.22,4.10±0.15,4.40±0.36,3.20±0.27,2.60±0.18,0.12±0.02 mL in the 6,12,24,36,48 and 72 h pleuritis groups respectively.AQP-1 were mainly expressed on visceral and parietal pleural mesothelial cells and capillary endothelial cells,and significantly increased in all pleuritic rats The mRNA and protein expression of AQP-1 on parietal pleura increased after 6 h and reached peak level at 24 h in pleuritic groups.The mRNA and protein expression of AQP-1 on visceral pleura increased after 12 h and reached peak level at 24 h in pleuritic groups.The expression of AQP-1 on parietal pleura at 12 h and 24 h in pleuritic groups was correlated positively with the volume of pleural effusion(r=0.857,r=0.846,all Plt;0.01).The expression of AQP-1 on visceral pleura at 24 h in pleuritic groups was positively correlated with the volume of pleural effusion(r=0.725,Plt;0.05).Conclusion The expression of AQP-1 on pleura were increased in rats with e carrageenan-induced pleural effusion.AQP-1 may play a role in pleural fluid transportation in pleural effusion.

  • Progress in clinical treatment of extrinsic allergic alveolitis

    Extrinsic allergic alveolitis is a general term for type Ⅲ or Ⅳ allergic pneumonia caused by repeated inhalation of various antigenic organic dusts and low molecular weight chemicals in susceptible people. The lesions involve alveolar, pulmonary interstitial, and airway. The main clinical manifestations are cough, expectoration, and dyspnea. Clinically, extrinsic allergic alveolitis is classified into acute, subacute, and chronic forms. Extrinsic allergic alveolitis has a great impact on the pulmonary function of patients. Timely treatment will improve clinical symptoms and inhibit the development of disease. The current treatment plan is mainly avoiding exposure to antigen, glucocorticoid therapy, immunosuppressive therapy, anti-fibrotic therapy, and lung transplantation.

  • Access to healthcare and its determinants among Chinese diabetic patients

    ObjectiveTo provide policy suggestions concerning the distribution of health resources between urban and rural areas and management and education of diabetes, this study depicted the current status of access to healthcare and analyzed its determinants among Chinese diabetic patients.MethodsMultivariate ordinal logistic regression and multivariate binary logistic regression were employed to analyze the effects of socioeconomic status and urban-rural disparities on health access.ResultsMultivariate results suggested that urban patients were more likely to conduct more blood glucose tests (P<0.000 1) and receive more self-care suggestions from physicians (P=0.02). After controlling all other covariates, patients graduated from secondary schools and those with vocational school degrees or above were 1.61 and 2.44 times more possible to take more blood glucose tests.Conclusions There exists significant urban-rural disparities of access to healthcare among Chinese diabetic patients. Education may be a key factor of access to healthcare among Chinese diabetic patients. It’s highly recommended to implement education programs on diabetes management in rural areas, where the education status and demographic factors should be considered. The distribution of health resource in rural areas requires more policy and governmental support.

  • Research on the operation mode of scientific research incentive mechanism in a large general hospital

    The operation mode of scientific research incentive mechanism in West China Hospital of Sichuan University is closely connecting individual needs with organizational objectives, and coordinating and adjusting again through communication and feedback. It can play an incentive role continuously and actively promotes the development of hospital scientific research. But the incentive mode, research funding management, research output rate, strengthening of effective communication and other aspects need to be constantly optimized and improved. Based on Porter Lawler’s comprehensive incentive theory, this paper explores and summarizes the operation mode of scientific research incentive mechanism in West China Hospital of Sichuan University. Finally, the paper puts forward suggestions, which aims to provide reference for the construction of scientific research incentive mechanism in large general hospitals.

Methods Two communitis in Chengdu were selected by randomized cluster sampling method. The morbidity and mortality in 132 303 people were calculated by prospective tracing. Results The annual incidence was 217.68 per 100 000, and the annual mortality was 49.13 per 100 000 in 2008. The annual incidence was 239.60 per 100 000, and the annual mortality was 41.57 per 100 000 in 2009. The age-standardized incidence was 216.01 per 100 000, and the age-standardized mortality was 43.61 per 100 000 in the two years. Ischemic cerebral apoplexy exceeded half of all and had a highest constituent ratio. The incidence Increased with the age (χ2=1 095.11, Plt;0.001), while there was no significant difference between the male and female (χ2=2.367, P=0.124). Conclusion The incidence of cerebral apoplexy in Chengdu City is similar to the average incidence of our country, and the mortality is lower than that of the average mortality.

    Objective To investigate the expression of aquaporin-1( AQP-1) in pleural mesothelial cells ( PMCs) and the influence of glucose thereupon. Methods Rat PMCs were isolated, cultured, and divided into two groups, ie. a glucose group, cultured with glucose of different concentrations for 24 hours,and a control group, cultured in D-MEM/ F-12 medium. The 100 mmol / L glucose group was administered at the time points of 6, 12, 18, and 24 hours respectively. RT-PCR and Western blotting were used to analyze the mRNA and protein expression of AQP-1. Results The absorbance values of AQP-1 protein expression were 54. 02 ±4. 61, 127. 84 ±9. 41, and 231. 62 ±22. 63, respectively in the PMCs treated with glucose of the concentrations of 50, 100, and 200 mmol / L, all significantly higher than those in the control group( 22. 45 ±2. 16, all P lt; 0. 01) . The absorbance values of AQP-1 protein expression were 24. 68 ±2. 56, 58. 68 ±3. 67, 89. 61 ±6. 62, and 113. 41 ±7. 65 in the PMCs treated with glucose of the concentration of 100 mmol / L after 6, 12, 18, and 24 hours, all significantly higher than those in the control group ( 11. 81 ±1. 45, P lt;0. 01) .Conclusions Glucose induces the expression of AQP-1 mRNA and protein.
