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 report the clinic experience of tr eatment of severe pelvic fracture in order to improve the early diagnosis and operation of the injury.Methods We retrospectively studied the clin ic data of106patients admitted to our hospita l for severe pelvic fracture from Apr il 1994to May 2002.Results The main causes for pelvic fracture were traffic accident injury(69cases,65.1%)and falling accident injury(31cases,29.3%).87cases were in the survival group,and 19cases in the death group,with t he mortality of about 17.9%.In the death group,10di ed from hemorrhagic shock,4of severe cerebral injury,3from MOF,and 2from ARDS.32cases with pelvic f ractures were treated by opening red uction and internal fixation,91.7%of which achieved good results.Conclusion In the treatment of severe pelvic fra ctures,prehospital emergency care is very important.Complicated severe injuries should be treated pr omptly and pelvic fractures be fixed with internal fixation as soon as possibl e.

Objective To study the clinical outcome of thoracolumbar fractures treated by ante rior route decompression,bone-graft-fusion and internal fixation.Methods 51cases of thoracolumbar fractures from Jun1994to Mar 2002were treated by anterior route decompression,bone-graft-fusion and internal fixation,of w hich32cases by Kaneda system and 19cases by Z-Plate system.Their clinical data were analyzed.Results The patients were followed up from five months to eight years(average of 3.5years).45cases had a good anatomic reduction and maintain thoracic-lu mbar lordosis.48cases gained one to three Frankel grades of neurologic r e-covery as a consequence of operation.Conclusion Kaneda internal fixation has the characteristics of low cost,neurological decompression and reliable fixation;and Z-Plate systems has the advantages of simple manipul ation,intrinsic stability,less complications and good biocompatibility.

AIM: To determinate the content of verbascoside in Shenqiyinao Capsules (Fructus Lycii, Herba Cistanches, Rhizoma Polygonati, etc.). METHODS: Waters C 18 column was used and acetonitrile-methyl alcohol-1% acetic acid solution was used as a mobile phase. The detection wavelength was set at 334nm. RESULTS: The linear range was in the range of 0.206~1.85?g, and the average recovery was 96.6% and RSD was 2.5%, respectively. CONCLUSION: The method can prevent from impurities effectively and can be applied to the quality control of Shenqiyinao Capsules.

Objective To study the feature of immunoglobulin complementarity determining region 3 (CDR3) gene in neonates of different gestational age (GA), and the effect of neonatal maturity on the diversity of CDR3 nucleotide sequence. Methods DNA were extracted from cord blood of 10 neonates of very immature (25-30 weeks), 12 immature (31-36 weeks), and 11 mature (37-41 weeks). CDR3 sequence was amplified suing nested PCR technique then cloned and sequenced. Results 1. There was a CDR3 length of 29.4±7.8, 32.4±9.2 and 40.8±10.7bp, including NDN length of 13.5±5.6, 16.1±7.8 and 22.0±8.5bp respectively in very immature, immature and mature neonates. 2. DP73 and DP75 were preferentially used in very immature and immature neonates, VH5, DP73 and DP75 were used in mature neonates. The usage rate of DP73 and DP75 reduced, whereas VH5 was raised with GA increasing. 3. For D gene segment, there was a frequent use of DN, DQ52 and DXP in very immature neonates, whereas DXP, DLR and DN in immature and mature neonates. 4. JH4 usage was preferential, followed by JH6 in all neonates, and their usage rate was decreased with GA increasing. 5. 63.3%, 68.8% and 92.0% of CDR3 sequence respectively in very immature, immature and mature neonates have an open reading frame with 303bp long encoding 101 residues. Conclusion During the early life of neonates, VH-D-JH rearrangement of IgH gene is in an active condition, but the diversity is limited. Humoral immunity is a gradual development with increasing GA. Both heterogeneity and similarity of CDR3 sequence exists in neonates with different GA.

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.
