Objective To study the threshold effect of government health expenditure on residents' health.Methods Using threshold panel data model to perform the empirical research.Results There is threshold effect of government health expenditure on residents' health.There are two threshold values.As the increase of the proportion of the government health expenditure to the total fiscal expenditure,it has two changes of the impact on the health of residents.Conclusion The government should increase the health expenditure,and increase the proportion of the government health expenditure to the total fiscal expenditure,but the government should not blindly pursue the high input of health expenditure,focus on the efficiency of health expenditure,and avoid of resource waste.

Objectives To detemline whether apoptotic cell death is involved in rat cardiac allograft rejection and investigate the relevance of apoptosis with acute rejection and its implication.Methods Groups of Wistar rats underwent heterotopic heart transplantation from allogeneic SD or syngeneic Wistar rats.The cardiac grafts were harvested at 1,3,5,or 7 days after transplantation and underwent the detection of apoptotic cell death using in situ terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling(TUNEL).Histopathological rejeclion grade and apoptotic index(AI)were analyzed.Results The incidence of apoptotic cells was increased steadily over time in allografts,in contrast to syngeneic grafts.The apoptotic cells in allografts were mainly cardiac myocytes and few infiltrating lymphocytes.The AI of rejection grade 1,2,3 and 4 was significantly higher than that of rejection grade 0(P<0.01).Conclusions TUNEL can display apoptosis of single cell in situ.Apoptosis is an important mechanism of tissue injury in acute cardiac allograft rejection in rats.Myocyte apoptosis can be used as a valuable index to estimate the injury of grafts and monitor acute rejection.

Objective To evaluate the effect of Toxoplasma gondii infection on immune function of the rat recipients and onset of Toxoplasmosis after heart transplantation and its correlation with the use of Cyclosporin A(CsA). Methods ELISA was used to detect recipient's specific circulating antigen (CAg) and antibodies (IgG, IgM) after the transplantation. T lymphocyte subsets in peripheral blood were examined by using immunofluorescence stain and flow cytometry (FCM) before and after heart allograft 5,10,15,20 days in rats. Results The use of CsA increased the risk of infection by T. gondii and accelerated the increase of CD8 + T lymphocyte after the transplantation. The incidence of donor acquired T.gondii infection was higher than that of reactivated silent infection in recipients before operation. The percentage of CD8 + T lymphocyte was evidently elevated due to the onset of toxoplasmosis and the ratio CD4 +/CD8 + was reduced or inverted in the meanwhile. Conclusion The immune suppression after use of CsA was the main reason leading to an activation of the silent infection of T.gondii . CD8 + was the main cytotoxic cell elevated during the infection.

Objective To explore the relationship between peripheral Th17 cell number and chronic gastritis in Helicobacter pylori(H.pylori)-infected children.Methods Children were diagnosed as chronic gastritis by endoscopy.The degree and activity of inflammation were graded by histopathology examinations.The patients with both 13C urea breath test and urease test positive were diagnosed as H.pylori infection.The peripheral Th17 cell number was measured by flow cytometry and expressed as a ratio to total T cell.Results The Th17 cell number in HP group (chronic gastritis with H.pylori infection,n =33),non-HP group (chronic gastritis without H.pylori infection,n =24) and normal controls (n =15) were (1.55 ±0.30)％,(1.06 ±0.33)％,and (1.04 ±0.35)％,respectively.HP group included a statistically higher Th17 cell number than the other groups (all P ＜ 0.05),while no obvious difference was found between non-HP group and controls (P ＞ 0.05).According to the degree of inflammation,the chronic gastritis with H.pylori infection was categorized into non-apparent (n =10),mild (n =8),moderate (n =9) and severe (n =6) subgroups.The Th17 cell number in each subgroup was (1.64 ± 0.21)％ (non-apparent),(1.61 ± 0.23)％(mild),(1.25 ± 0.29) ％ (moderate) and (1.75 ± 0.20) ％ (severe),respectively.The moderate group had a lowest Th17 cell number among 4 groups (P ＜ 0.05).And significant differences did not exit in the other 3 groups (P ＞ 0.05).The HP group patients with different inflammatory activity had a Th17 cell number of (1.23 ±0.25)％ in nonapparent (n=15),(1.53 ±0.15)％ in mild (n=6),(1.55 ±0.32)％ in moderate (n=6) and (1.71 ±0.35)％ in severe (n =6) subgroup,respectively.However,there were no significant differences among 4 subgroups (P ＞ 0.05).Conclusions In the progress of chronic gastritis with H.pylori infection,Th17 cells may play a role as a double-edged sword by protecting and fighting against H.pylori infection and immunopathologic insults.This would provide more insights into the treatment of H.pylori infection.

ObjectiveTo explore the personality traits of Han Chinese women with recurrent depression.MethodsAssessed by the Big Five Inventory (BFI),a comparison research was conducted between 118 Han Chinese women with recurrent depression and 65 sex,race and culture background matched health controls.Results Han Chinese women with recurrent depression scored lower in extraversion,conscientiousness and openness ( 17.93± 5.43,30.24 ± 5.94,30.03 ± 7.33 ) than matched controls ( 20.72 ± 3.79,31.94 ± 3.84,32.75 ± 5.32 ),while scored higher in neuroticism (21.38 ± 3.91) than the later one ( 27.57 ± 6.19 ).A binary logistic regression model,with group (case vs.control) as dependent variable and extroversion,conscientiousness,openness and neuroticism as independent variables,was built to assess each personality dimension's independent impact on recurrent depression.It came out to be that only extraversion ( OR =0.881,95％ CI =0.083-0.966,P=0.007) and neuroticism ( OR =1.225,95％ CI =1.134-1.323,P ＜ 0.01 ) were statistically significantly associated with recurrent depression ( P＜ 0.05 ).ConclusionIn the big five personality model,extraversion and neuroticism might act as independent personality traits to impact Han Chinese women with recurrent depression in a positive and negative way respectively.

BACKGROUND: Matrix metalloproteinase (MMP) is a kind of protease family, its activity can be inhibited by tissue inhibitor of metalloproteinase (TIMP), especially by TIMP-3.OBJECTIVE: To fully isolate and purify natural TIMP-3, and to create enzyme-linked immunoassay of TIMP-3.DESIGN: Single-sample observation SETTING: Central Laboratory of Shenyang Medical College MATERIALS: Human placenta from Department of Obstetrics & Gynecology, Fengtian Hospital Affiliated to Shenyang Medical College (Informed consent was obtained from the relatives of patients) and MMP-1 from Research Institute. Fuji Chemical Industries, Ltd.METHODS: This experiment was conducted in the Central Laboratory of Shenyang Medical College between March 2001 and May 2002. Firstly,4 mol/L urea Tris-buffer solution (pH8.0) was used to prepare homogenate solution of placenta. Secondly, homogenate solution was performed chromatography through CM52 positive ion-exchange resin and Sephacryl S200 gel filtration. Thirdly, relative molecular weight and purity were detected by SDS- polyacrylamidedel gel electrophoresis (SDS-PAGE).Fourthly, Western blotting was used to identify the characters of purified protein. Fifthly, the inhibitory rate of TIMP-3 to MMP-1 was measured with immumofluorescence method.MAIN OUTCOME MEASURES: ① The relative molecular mass of protein showed by PAGE. ② Results of Western blot. ③ The inhibitory rate of TIMP-3 for MMP-1. ④ The recovery rate of TIMP-3 following purification.RESULTS: ①The isolated and purified TIMP-3 from human placenta consisted of non-glycosylated and glycosylated protein, with relative molecular mass of 24 000 and 27 000, respectively. ② The inhibitory concentration of non-glycosylated and glycosylated TIMP-3 was 1.1×1010 mol/L and 1.2×1010 mol/L respectively to MMP-1. The inhibitory concentration of placenta-derived TIMP-3 was significantly higher than that of recombinant TIMP-3 for MMP-1. ③ The recovery rate of TIMP-3 was 23.4% following two-step chromatography.CONCLUSION: Extracellular matrix of human placenta-derived TIMP-3 consists of non- glycosylated protein and glycosylated protein; Two kinds of purified TIMPs-3 have remarkable inhibitory concentration for MMP-1, and significantly higher in comparison with recombinant metalloproteinase inhibitory factor-3.
