Objective To probe into a doctor-seeking medical management model for China's urban hypertension patients under medical insurance, and enhance the level and quality of medical insurance management. Methods Hypertension patients were surveyed with a structured questionnaire, and the staff at community health centers and medical insurance management centers received qualitative interview. Results The hypertension patients are found to see doctors mostly at community health centers and tertiary hospitals; complaints among hypertension patients for existing medical insurance vary with their areas, mostly targeting on complicated reimbursement procedure, high threshold of medical insurance payment and low level of reimbursement. Recommendation Experiment with the single-disease payment for hypertension, with the total prepayment in per capita and per disease; greater efforts in hypertension control in communities, with more favorable medical insurance policies for communities;elevated collaboration with medical institutions at all levels, and building and standardizing the management information network for hypertension patients.

Objective To proceed deep data mining in large database obtained by Cancer Genome Anatomy Project and to distinguish the difference expression genes of gastric carcinoma.Methods The 300,783 serial analysis of gene expression records from 4 libraries of gastric cancer and 2 libraries of normal gastric tissue in database of the Cancer Genome Anatomy Project were analyzed by digital gene expression displayer.Results The 201 difference expression tags represented 136 genes(54 up-regulated and 82 down-regulated) and 65 ESTs(24 up-regulated and 41 down-regulated) were distinguished,and these genes were involved in biological process and signal transduction pathways,such as cell cycle regulation,cell proliferation and apoptosis.The gene expression profile in whole body normal and cancer tissues of PTMA were constructed by digital Northern based on serial analysis of gene expression database and by virtual Northern based on cDNA database,respectively.Conclusion The difference expression genes of gastric cancer can be distinguished effectively with bioinformatics,and the results will guide our further molecular biology research.If validated by molecular biology experiment,the difference expression genes will be used as molecular targets of gastric carcinoma.

Objective To investigate the incidence and influence factors of stress ulcer SU) in traffic injury patients. Methods Clinical data of 362 traffic injury patients were studied retrospectively.Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ) score was carried out for all the patients.All the patients had gastroscopy and a comparative analysis was done on the SU patients with or without bleeding and the patients without SU. Results The patients with extensive burn in traffic injury were more susceptible to SU as compared with other trauma patients,with statistical difference ( X2 =7.028,P ＜ 0.05 ).The incidence of SU or hemorrhage was increased with higher APACHE Ⅱ score.The incidence of SU hemorrhage in patients with diabetes or cardiopulmonary disease was significantly higher than that in patients without diabetes or cardiopulmonary disease ( P ＜ O.05 ). Conclusions Traffic injury patients should receive routine gastroscopy.APACHE Ⅱ score has some predictive value for SU or hemorrhage.The incidence of SU hemorrhage is also determined by combined factors of underlying diseases and treatment methods.

The effects of mifepristone (RU486) on the productions of plasminogen activator and progesterone in rat granulosa cells and luteal cells were studied by fibrin overlay method and radioimmunoassay method. The results showed that RU486 could significantly antagonize tPA activity and progesterone production enhanced by human chorionic gonadotropin (hCG). Secretion of tPA from luteal cells was significantly promoted by RU486 with or without prostaglandin F2a (PGF2α), but progesterone production in luteal cells was markedly inhibited with the same treatment. With method of tissue culture, the results showed that RU486 was capable of stimulating tPA and urokinase (uPA) activity in endometrium of pregnant rats. These findings indicated that antifertility of RU486 might be partly mediated through plasminogen activator-plasminogen activator inhibitor system.

Objective To evaluate the risk factors for the postoperative acute renal failure requiring dialysis (ARF-D)after heart valve surgery. Methods Adult patients (age≤18 years) underwent valve surgery with preoperative serum creatinine ＜300 μmol/L were included between January 2005 and December 2008. Fifty patients developed ARF-D within 30 days postoperatively (ARF-D group). While random 220 patients had the same operation without ARF-D served as the control group. Univariate analysis and multivariable logistic regression were used to identify risk factors of ARF-D after valve surgery.Results The incidence of ARF-D was 1.78%, and the early mortality rate was 65.5%. Multivariate analysis identified the following independent risk factors of ARF-D: age, previous cardiac surgery, preoperative serum creatinine, NYHA class Ⅳ,and low cardiac output syndrome. ARF-D group had a longer hospital stay and ICU stay than that of the control group ( P ＜0.001 ). Conclusion Conclusion ARF-D had a higher mortality rate and longer hospital stay following heart valve surgery.Age, previous cardiac surgery, preoperative serum creatinine, NYHA class Ⅳ, and low cardiac output syndrome were the independent risk factors of ARF-D after heart valve surgery.
