Objective:To put forward some suggestions for the national health development in the filed of health expenditure indicators .Methods:Two health expenditure indicators and four health outcomes indicators were chosen from WB and WHO official websites , and researches on the relationship between health expenditure and outcomes were conducted .We put forward proposed value of the health cost indicator .Results: With different levels of GDP per capita , the scatter diagram of health expenditure and GDP per capita had different rules .When health outcomes were taken into consideration , the rules were the same .When GDP per capita was at different level , better health outcomes were not related to higher health expenditure .Input-output ratio should be taken into consideration fully . Suggestions:The study should be dynamic as GDP develops .More factors can be added in the research , if the data of the factors is available .In this study , the GDP per capita was divided into 4 sections .The division standard of the GDP per capita can be more delicate .What is more important for the development of health expenditure is not contin-uing input , but better input-output ratio because of diminishing of marginal returns .One set of standards cannot be a-dapted to all countries and districts .We should give full consideration to the improvement of people's health instead of increasing input because the ultimate goal is the former .

OBJECTIVETo investigate the effect of total flavonoids of astragalus on the expression of endoplasmic reticulum chaperone, calumenin and connecxin 43 (CX43) in suckling mouse myocardium with myocarditis caused by coxsackievirus B3 (CVB3).

METHODSThe primary culture of suckling mouse myocardium cells were randomly divided into control group, CVB3 infected group and total flavonoids of astragalus group. Firstly, to confirm the identity of the suckling mouse myocardium, α-SMA was monitored by immunohistochemistry method. Then the protein expression changes of endoplasmic reticulum chaperone-glucose regulatory protein 78 ( GRP78), calumenin and CX43 were detected by Western blot.

RESULTS(1) Compared with that of the control group, the GRP78 expression level in CVB3 infected group was improved, the expression levels of calumenin and CX43 were all reduced. (2) Compared with that of CVB3 infected group, GRP78 expression level was decreased, and the expression levels of calumenin and CX43 were increased in total flavonoids of astragalus group.

CONCLUSIONCVB3 infection may cause endoplasmic reticulum stress of rat myocardium cells by increasing the expression of GRP78 and decreasing the expression of calumenin and CX43. On the other hand, total flavonoids of astragalus can reduce the expression of GRP78 and increase the expression of calumenin and CX43.The results of this experiment may be closely related to the effects of anti-arrhythmia with viral myocarditis caused by CVB3.

Objective To study the correlation of HBV infection pretransplantation and posttrans-plantation and HCMV recurrence after liver transplantation (LT). Methods We reviewed historical patient medical records of LT patients in recent two years in our hospital. All the patients were divided into HBV in-fection group and a control group based on a peripheral blood HB antigen assay before LT. The HBV infec-tion group was divided into HBV reactive infection group and HBV non-relapse group. HCMV antigen pp~65 was detected by immunohistochemical methods. HB antigens and antibodies were detected by time-resolved fluorescence immunoassay, and liver enzyme levels were detected by conventional methods. Results Com-paring two groups of patients, pp65-positive rates of LT patients with HBV infection and control group pa-tients were 84.3% and 57.9% respectively (P=0.024). While in HBV recurrence infection group and non-recurrence infection group, the incidences of HCMV recurrence were 90.9% and 83.3% (P=0.843). The changes in the liver transaminases level in both groups have no statistical significance (P>0.05). Conclusion Pretransplantation HBV infection may increase the incidence of HCMV recurrence. Posttrans-plantation HBV reactive infection, however, may not increase the incidence of HCMV reactive infection. Meanwhile, compare with either HBV infection or HCMV infection alone, co-infection may not serious in liv-er enzymes levels.

Objective To evaluate the role of the beta3 subunit of the voltage-gated sodium channel (Scn3b) in neuropathic pain in mice.Methods The target gene Scn3b was embedded in the vector pBROAD-mcs and pBROAD3-mcs-Scn3b plasmid was then obtained.The primary mice were bred.The primary mice mated with C57/B6 mice and the transgenic mice were then generated.DNA,RT-PCR and Western blot experiments were performed to confirm the mice in which Scn3b was over-expressed.The mice with Scn3b over-expression multiplied rapidly to carry out the follow-up experiment.Ten transgenic mice (Scn3b group) and 10 control mice in the same litter (Con group) of both sexes,aged 2 months,weighing 25-30 g,were randomly chosen to establish the model of neuropathic pain.The mechanical pain threshold was measured before operation and on 3,5,7 and 14 days after operation.Results There was no significant difference in the mechanical pain threshold at each time point between the two groups (P ＞ 0.05).Conclusion Scn3b is not involved in the development and maintenance of neuropathic pain in mice.

Objective To investigate the correlation between CT perfusion parameters of pulmonary carcinoma and standardized uptake values(SUV)derived from ~(18)F-fluoro-deoxyglucose positron emission tomography(~8F-FDG PET)and tumor microvessel density(MVD),and to determine the validity of CT perfusion in assessing tumor angiagenic activity of pulmonary carcinoma.Methods Fifty patients(mean age 57.5,17 females)with pulmonary carcinoma underwent CT perfusion using 16-slice helical CT.Blood flow(BF,ml?100g~(-1)?min~(-1)),blood volume(BV,ml?100g~(-1)),mean transmit time(MTF,s)and permeability surface area product(PS,ml?100g~(-1)?min~(-1))were analyzed.SUV of PET was calculated in 14 patients.The CD34 immunohistochemical staining was used for tumor microvessel counting.CT perfusion parameters of pulmonary carcinoma were correlatively studied with SUV and tumor MVD.Pearson's correlation analysis was performed to evaluate the association between CT perfusion parameters and SUV and MVD.Results The average values of BF,BV,MTT and PS were 97.30 ml?100g~(-1)?min~(-1), 8.86 ml?100g~(-1),6.75 s and 34.52 ml?100g~(-1)?min~(-1),respectively.The average value of MVD was 61.82/FOV.The mean value of SUV was 5.96.There was positive correlation between BF and SUV(r= 0.727,P

Objective To study effectiveness and effect on the internal environment of exchange transfusion using peripheral arteries and veins.Methods Exchange transfusion were performed through the peripheral arteries and veins on 22 cases of newborn infants with severe hyperbilirubinemia.Blood electrolyte,blood routine,blood bio- chemistry were measured before and after change blood.Vital signs were monitored electronically recorded.Results Total bilirubin was(595.28?134.44)?mol/L before exchange transfusion and(275.17?74.05)?mol/L after ex- change transfusion(P

Objective To investigate JC virus(JCV) infection in kidney transplant recipients and its influence on graft function and also initially explore JCV infection factors. Methods A total of 49 kidney transplant recipients and 24 health examination persons were enrolled in our study, JCV DNA was measured using nested qualitative polymerase chain reaction assays of urine, while CMV DNA was measured by common qualitative polymerase chain reaction assays of urine. JCV infection factors, such as age, male, immunosuppressive therapy, cytomegalovirus(CMV) infection were analyzed by Binary Logistic Regression, and glomerular filtration rate(GFR) was selected as a index of kidney function and the difference of GFR between JCV-infected and non-infected patients was compared using t test. Results JCV was detected in 42.9% of kidney transplant patients and 4.2% health examination persons. CMV infection and Pred + MMF + CsA triple immunosuppressive regimen were found to be the risk factors of JCV infection. No difference of GFR was observed between JCV infected and non-infected patients (86.470 ± 29.990 and 84.060 ± 33. 729 for each; t =0. 259, P =0.797). Conclusion JCV is frequently detected in kidney transplant recipients. CMV infection and using of Pred + MMF + CsA triple immunosuppressive regimen can significantly increase the risk of JCV infection. While, graft function was not influenced by JCV infection in kidney transplant patients.

OBJECTIVETo study the effect of matrine and oxymatrine on proliferation and the expression of Stat3, Stat5 mRNA in SMMC-7721 cell line.

METHODTreated with matrine and oxymatrine, the inhibitory effect on SMMC-7721 cell proliferation was detected by MTT, double fluorescence labeling was applied to measure the apotosis ratios of SMMC-7721cells, the expression of Stat3 and Stat5 mRNA in SMMC-7721 cell line were assessed with RT-PCR.

RESULTMatrine and oxymatrine could inhibit the proliferation and induce the apoptosis of SMMC-7721 cells and it was time and dose dependent, the expression of Stat3 and Stat5 mRNA in SMMC-7721 cell with matrine and oxymatrine were significantly lower than those in control group (P<0.05 or P<0.01). Compared with the same dose of matrine and oxymatrine, matrine showed stronger effect on cell proliferation, apoptosis, and Stat3 and Stat5 mRNA (P<0.05 or P<0.01).

CONCLUSIONMatrine and oxymatrine inhibited the proliferation and induced the of SMMC-7721 cells significantly, the mechanism of which might be related to the down-regulation of stat3 and stat5 mRNA and inhibition of the signaling transduction pathway.

The study was to investigate the proliferation and apoptosis effect of nociceptin/orphanin FQ (OFQ) on 562 cells in vitro. Inhibition of K562 cells proliferation was measured by MTT assay. Morphological assessment of apoptosis was performed with Wright staining and transmission electron microscope. The apoptosis peak was measured by flow cytometry. DNA fragmentation was visualized by agarose gel electrophoresis. The results showed that OFQ time-dependently and no-dose-dependently inhibited the proliferation of K562 cells at concentrations of 10(-6) - 10(-13) mol/L. Discrete maximum of cytolytic activity was detected at concentrations of 10(-6) - 10(-7), 10(-9), 10(-12) mol/L. Compared with the control group K562 cells, the cells treated with OFQ at concentration of 10(-9) mol/L for 72 hours showed typical characteristics of apoptosis under transmission electron microscope. Apoptosis peak was found by FCM at concentration of 0, 10(-7), 10(-8), 10(-9) mol/L of OFQ for 72 hours, apoptosis rates were 0%, 22.8%, 23.8% and 26.5% respectively. DNA agarose gel electrophoresis revealed nuclear fragmentation (DNA ladder). It is concluded that OFQ can inhibit the proliferation of K562 cells and induce the apoptosis in K562 cells.
