Background The sex hormones plays an important role in the incidence of dry eye,especially for the regulation of function.However,the effects of sex hormones on lacrimal gland epithelial cells are below understand.Objective This study was to investgate the effects of estradiol and testosterone on the apoptosis of lacrimal gland cells induced by H2O2.Methods The lacrimal gland tissue was obtained from 2- or 3-month-old clean male New Zealand rabbits and the lacrimal gland epithelial cells were cultured in vitro using esplant culture method.The cells were identified by pan cytokeratin antibodies with immunocytochemistry.lacrimal gland epithelial cells were incubated in the 96 well plate at the density of 5 × l04 cells/ml for 44 hours.Estradiol or testosterone with the concentrations of 1 × 10-5,1 × 10-6,1 × 10-7,1 × 10-8 mol/L were added into the medium for 24 hours respectively and 1× 10-4 mol/L H2O2 treated the cells for 1 hour to induce the apoptosis in experimental groups.The cells treated by only 1 × 10-4 mol/L H2O2 were used as apoptotic control group,and the cells cultured by regular method were used as blank control group.The cell viability in different groups was detected using MTT at 570 nm ( A570 ),and the apoptotic rates of the cells were assayed using Annexin V/PI double staining.This use and maintain of experimental animals followed the Regulation for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The cultured cells showed the irregular polygon in shape,and about 80％ cells was positive response for cytokeratin.MTT assay showed that the lower A570 values were detected in the H2O2-induced group,various concentrations of estradiol or testosterone groups compared with blank control group (P＜0.01 ).The A570 values in 1 × 10-5,1 × 10-6,1 × 10-7 mol/L estradiol groups or 1 × 10-6 mol/L testosterone group were significantly higher than ones of H2 O2-induced group (P＜0.01 ).Compared with corresponding concentrations of testosterone groups,the A570values in various concentrations of estradiol groups were elevated( P＜0.01 ).The apoptosis rates at the early and later phase were significantly declined in both estradiol group and testosterone group in comparison with H2 O2-induced group (P ＜ 0.01,P＜ 0.05 ),and those in estradiol group were lower than the testosterone group( P＜0.01,P＜0.05 ).Conclusions Estradiol and testosterone suppress the apoptosis of lacrimal gland cells induced by H2O2,and the stronger effect is found in estrogen.The inhibition of estrogen on lacrimal gland cell apoptosis show a dose-dependent manner to some extent.

OBJECTIVETo observe the efficacy of treatment of acute leukemia by Shengfu Injection (SFI) in combination with chemotherapy and the effect of treatment on T-lymphocyte subsets (CD4, CD8, CD4/CD8), serum interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha).

METHODSSixty-one patients with acute leukemia of initiatory treating were randomly divided into two groups, the 31 patients in the treated group were treated with SFI plus chemotherapy and the 30 patients in the control group treated with chemotherapy alone. The remission rate, changes of absolute number of peripheral mature neutrophils, T-lymphocyte subsets, serum levels of IL-6 and TNF-alpha before and after treatment were observed.

RESULTSThe remission rate was higher in the treated group than that in the control group but the difference was insignificant (P > 0.05). The restoring of peripheral mature neutrophils in the treated group was higher than that in the control group, from the 3rd week of treatment, the difference was significant (all P < 0.05). CD4 and CD4/CD8 ratio after treatment increased in both groups, the increment was more obvious in the treated group than that in the control group significantly (P < 0.05). Serum levels of IL-6 and TNF-alpha lowered in both groups after treatment significantly(all P < 0.01), but the decrement was greater in the treated group with significant difference to the control group (P < 0.05).

CONCLUSIONSFI could improve and regulate the immune function in acute leukemia patients undergoing chemotherapy and enhance the therapeutic effect.

OBJECTIVETo observe the effect of Shenfu injection (SFI) and influence on T-lymphocyte subset, serum level of interferon-gamma(IFN-gamma), tumor necrosis factor-alpha(TNF-alpha), interleukin-2(IL-2) in patients with chronic aplastic anemia (CAA) based on treating with stanozol and cyclosporin A.

METHOD60 patients with CAA were randomly divided into two groups, 30 patients in the SFI group were treated with SFI (100 mL which contains Ginsenoside 0.8 mg x mL(-1) and aconitine 1.8 microg x mL(-1) by adding it in 500 mL of 5% glucose every day) plus stanozol and cyclosporin A and 30 patients in the control group treated with slanozol and cyclosporin A alone for 2 months. The clinical efficacy was observed. The change of T-lymphocyte subset analyzed by flow cytometry and the levels of serum IFN-gamma, TNF-alpha, IL-2 measured with ELISA method were also observed before and after treatment.

RESULTAfter treatment, the total effective rate of the SFI group was higher than that in the control group, but it did not showing significant difference. The CD4/CD8 levels were significantly increased (1.76+/-0.49, P< 0.01) and CD8 levels were significantly lowered (22.57+/-6.30, P < 0.01) in the SFI group after treatment. Serum levels of lFN-gamma, TNF-alpha and IL-2 were lower in both groups, and the level of TNF-alpha and IL-2 in the SFI group (0.710+/-0.213) ng x L(-1) and (0.639+/-0.247) ng x L(-1) was significantly lowered than that in the control group (P < 0.05, P < 0.01).

CONCLUSIONSFI might believe the hemopoietic inhibition so as to promote the recovery of hemopoietic function through improving the T-lymphocyte subset and reducing the release of hemopoietic negative regulatory factors such as IFN-gamma, TNF-alpha and IL-2.

Objective： The current study was designed to investigate the effect of heat shock protein 70(HSP70) on stability of mutant p53 protein. Methods： Retroviral recombinant expressing antisense HSP70 RNA was constructed and transfected into MCF7/Adr breast cancer cells. The existence of foreign DNA was identified by PCR method and the HSP70 protein level was determined by Western blot analysis. The half-life of mutant p53 protein(mtp53) was measured by p53 stability assay. Results： The stable expressing strain(MAp70) from transfected cells was obtained through G418 selection. The foreign DNA in transfectant cells were confirmed by PCR, and the repression rate of HSP70 protein was 42％ . The half-life of mutant p53 in MAp70 cell was 12 hours, significantly lower than that of the control cells. Conclusion： Antisense HSP70 RNA can decrease the HSP70 protein level and significantly increase instability of mutant p53 protein in MCF7/Adr breast cancer cell.

Objective To estimate the association between three B-vitamin intakes and sociodemographic factors among adults in China.Methods We derived our data from the China Health and Nutrition Survey (CHNS) among 12,241 individuals aged 18–64 years. Log binomial regression was used to estimate adjusted prevalence ratios for factors associated with the inadequate intake of B-vitamins.Results Females with low incomes and living in the north had a higher prevalence of inadequate riboflavin intake than those with high incomes and living in the south. Both males and females living in a village had a higher prevalence of inadequate riboflavin intake than adults living in a city. Adults with low income, low education, and living in the north or in a village had a higher prevalence of inadequate niacin intake than adults with a high income, high education, and living in the south or in a city.Conclusion We found that income, region, and area of residence were associated with riboflavin intake. Education, income, region, and area of residence were associated with niacin intake. Well-tailored strategies and policies are needed to improve nutritional status in China.

Objective To discuss the clinical value of transabdominal sonography after bowl preparation in diagnosis of ileocecal valve syndrome ( IVS) .Methods The ultrasonic features of IVS in 37 cases were summerized and correlated with the follow-up findings after conservative treatment or the pathologic results after operation .Twenty-eight cases were confirmed by follow-up and 9 cases by operative pathology.Results Among the 37 cases of IVS,28 were idiopathic IVS (75.7%,28/37) and 9 were secondary IVS (24.3%, 9/37%).For the secondary cases, the primary diseases included 5 acute appendicitis,2 Meckel diverticulum,1 terminal ileitis and 1 carcinoma of ascending colon .The diagnostic accuracy rate of ultrasound was 89.2%(33/37).Misdiagnosis rate was 10.8%(4/37),including 1 case of idiopathic and 3 cases of secondary IVS .The IVS ultrasonic images coulde be displayed clearly using 7.0-10.0 MHz probes.In fasting examination,three ultrasonic characteristic signss were found in interminal ileum region at the right lower abdomen .And these features were bagel-shaped sign [91.9%(34/37),average size (1.9 ±1.6) cm ×(0.8 ±0.3) cm],short sleevelet-shaped sign [91.9% (34/37,average size (2.1 ± 0.4)cm ×(1.3 ±0.2) cm],and rose-shaped sign [83.8% (31/37),average size (1.4 ±0.2) cm × (1.0 ±0.2) cm].The shapes of some signs were changeable when the probe compressed .In the case of idiopathic IVS ,several pathologic changes could be seen on sonography after intestinal tract filling of oral 20%mannitol,including slight thickened mucosa and submucosa of erminalileum ,enlarged ieocecal valve and the crocodile-mouth sign.Conclusions Transabdominal ultrasonic examination with high frequency probe after bowl preparation plays an important role in diagnosis of IVS .The method is simple and accurate and should be recommended and applied clinically .

The liver injury induced by Polygonum multiflorum Thunb. (PM) was investigated based on idiosyncratic hepatotoxicity model co-treated with lipopolysaccharide (LPS) at a non-hepatotoxic dose. Sprague-Dawley (SD) rats were intragastrically administered with three doses (18.9, 37.8, 75.6 g crude drug per kg body weight) of 50% alcohol extracts of PM alone or co-treated with non-toxic dose of LPS (2.8 mg·kg(-1)) via tail vein injection. The plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities were assayed and the isolated livers were evaluated for histopathological changes. The dose-toxicity relationships of single treatment of PM or co-treatment of LPS were investigated comparatively to elucidate the idiosyncratic hepatotoxicity of PM. The results showed that no significant alterations of plasma ALT and AST activities were observed in the groups of solo-administration of LPS (2.8 mg·kg(-1), i.v.) or different dosage (18.9, 37.8 and 75.6 g·kg(-1), i.g.) of PM, compared to normal control group (P > 0.05); while significant elevations were observed in the co-administration groups of PM and LPS. Treatment with LPS alone caused slight infiltration of inflammatory cells in portal area but no evident hepatocytes injury. Co-treatment with LPS and PM (75.6 g·kg(-1), i.g.) caused hepatocyte focal necrosis, loss of central vein intima and a large number of inflammatory cell infiltration in portal areas. When further reduce the dosage of PM, significant increases of plasma ALT and AST activities (P < 0.05) were still observed in co-administration groups of LPS and PM (1.08 or 2.16 g·kg(-1)), but not in LPS or PM solo-administration groups. Nevertheless, the co-treatment of low dosage of PM (0.54 g·kg(-1)) with LPS did not induce any alteration of plasma ALT and AST. In conclusion, intragastric administration with 75.6 g·kg(-1) of PM did not induce liver injury in normal rats model; while the 2 folds of clinical equivalent dose of PM (1.08 g·kg(-1)) could result in liver injury in the LPS-based idiosyncratic hepatotoxicity model, which could be used to evaluate the idiosyncratic hepatotoxicity of PM.
