Objective To investigate the current policy of medical insurance expenditure control in Shanghai and put forward feasible advice. Methods Survey in 5 tertiary first-class hospitals in Shanghai involving 400 doctors and patients was conducted.The result of the questionnaire was tracked with Microsoft Excel 2000.The expense reports during 2001 to 2006 from the Office of Medical Insurance of Shanghai Renji Hospital was collected.All the data were statistically analysed. Results The global budget system was accepted by both the doctors and patients.Charging based on disease categories was proved a relatively satisfying method.Drug expenditure control was concerned by both the doctors and patients. Conclusion Ever since the global budget system of medical insurance is implemented in Shanghai,the medical insurance expenditure has been effectively controlled.The key point is the restraint of irrational consumption during the medical treatment.

The feasibility of using cord blood mesenchymal stem/progenitor cells (CB-MSPCs) to regenerate cardiomyocytes and the optimal inducing conditions were investigated. The CB mononuclear cells were cultured in low serum DMEM medium to produce an adherent layer. After expansion, the adherent cells were added into cardiomyocyte inducing medium supplemented with 5-azacytidine. Cardiogenic specific contractile protein troponin T staining was performed to identify the cardiomyocyte-like cells. The results showed that the frequency of CB-MSPCs clones in CB mononuclear cells was 0.5 x 10(-6) and about 1.3 x 10(7)-fold expansion was achieved within 20 sub-cultivation. After cardiogenic induction, 70% CB-MSPCs was differentiated into cardiomyocyte-like cells. It was indicated that low serum culture could expand CB-MSPCs extensively and the expanded CB-MSPCs could be induced to differentiate into cardiomyocyte-like cells in high efficiency.

Chlamydial infection in human urogenital tract induces inflammation and causes tissue damage and scarring. It is thought that cytokine production by the Chlamydia-infected cells plays a key role in chlamydial disease processes. Although many cytokines have been detected during chlamydial infection, little is known about the molecular mechanisms on how Chlamydia triggers and sustains the inflammatory cytokine cascades. In the current study, chlamydial infection of the human cervical epithelial cell line HeLa cells can induce the production of IL-8, IL-1α, IL-1β and IL-6. Using inhibitors for probing intracellular kinase signaling pathways required for the Chlamydia-induced cytokines, it was found that the Chlamydia-activated MAPK / P38 pathway is required for the chlamydial induction of IL-1α and IL-6 while both the Chlamydia-activated MAPK/ERK and MAPK/P38 pathways contribute to the production of IL-8.

Objective To evaluate the value of mistral-air inflatable blanket in neonatal temperature,postoperative complications,and the influence of the blood coagulation function after surgery undergoing general anesthesia.Methods A total of 60 newborns with laparotomy operation undergoing general anesthesia were randomly divided into two groups,the control group and the observation group,30 persons each group.The newborns were given mistral-air inflatable blanket in the observation group,and conventional methods in the control group,two groups were transferred to Postanesthesia Care Unit by incubator at 37℃.The introperative nasopharyngeal temprature,HR,MAP and SpO2 were recorded before induction (T0),30 minutes during operation (T1),extubated instantly (T2),15 minutes during PACU (T3),30 min during PACU (T4).The extubation time and the incidence of apnoea and hyoxemia were recorded after operation.PT,APTT,TT and Fib were tested before induction and extubated instantly.Results The temperature of intraoperative and postoperative period were higher in the observation group than the control group,the difference was significant(P ＜ 0.05).The heart rates of intraoperative and postoperative period is significantly higher in the control group than the observation group,the difference was significant(P ＜ 0.05);the mean arterial pressure were no significant statistical difference(P ＞ 0.05).The observation group extubation time were less than the control group,the difference was significant (P ＜ 0.05).There was no significant difference about the incidence of hypoxemia and apnea in two groups(P ＞ 0.05).The PT,APTT,TT and Fib in the observation group were better than the control group,the difference between the groups was significant(P ＜ 0.05).Conclusion Mistral-air inflatable blanket can effectively prevent the decrease of the body temperature during operation and PACU,reduce the exduction time and postoperative complications,and protect blood coagulation function.

Objective To observe the effect of electroacupuncture on improvement of learning and memory ability and the expression of connective tissue growth factor(CTGF)mRNA and protein in hippocampus in diabetic rats with cognitive impairment.Methods The rat diabetes model was induced by injecting streptozotocin(20 g/L),and then the rats were randomly divided into three groups:electro-acupuncture group(EA),diabetes-mellitus-untreated group(DM)and control group(CN).After four weeks of electroacupuncture treatment,blood glucose level was determined and the effect of electroacupuncture on learning and memory was examined with the device of Morris water maze.RT-PCR was used to detect CTGF mRNA level,and immunohistochemistry was used to detect CTGF protein expression.Results Blood glucose level and the latency period in DM group were increased compared with those in EA and CN groups(P

Objective:To determine whether implantation of an intraocular lens(IOL) with a modified prolate anterior surface results in reduced spherical aberration and improved contrast sensitivity after cataract surgery.Methods: Consecutively 72 eyes were selected from 53 senile cataract patients who had received phacoemulsification and IOL implantation in Peking University Eye Center.Each was randomly assigned to receive Tecnis Z9001 IOL or Sensar AR40e(both made by AMO).Three months after operation,the eyes underwent several tests including visual acuity,optometry and wavefront aberration examination.Mesopic contrast sensitivity test was measured with ROLAND BA-4 Contrastometer.Results: The eyes treated with Tecnis Z9001 had significantly less spherical aberration.The eyes treated with Tecnis IOL got lower C12 coefficient and RMS4 than those with Sensar AR40e(P value

The recombinant fusion protein staphylokinase-hirudin(rSFH) was purified from the high density-fermented engineered E.coli by means of ion-exchange chromatography (IEC) and gel filtration (GF). The purity of rSFH reached to more than 98% determined by RP-HPLC and SDS-PAGE, and the yield was up to 0.7g per liter of fermentation broth. The analysis of homologous dimmer of rSFH appeared during the purification and calculation of the surface hydrophobic area had been carried out by means of hydrophobic chromatography and MALD-TOF. The influence of sodium chloride and temperature on the behavior of rSFH reversible dimerization was analyzed by high performance sized- exclusive chromatography(HPSEC). It is concluded that the hydrophobic interaction played an important role in the reversible dimerization of rSFH.

The strain of DG7 isolated from the oilwater sample in DAGANG oilfield could produce surfactant ?acids and gas in the culture medium in which the diesel was sole carbon source .The strain was Gram-negative, motive, rod and growed facultatively in the 0 to 18.5% NaCl. Based on its characters, the strain was identified as a member of the genus Aeromonas, but there were some differences between this strain and the described species of this genus in some biochemical features, suggesting that it could be a new species of the genus.
