OBJECTIVE:To investigate the effects of Wenxin granule on the related indexes of senile patients with primary hy-pertension and acute left cardiac failure. METHODS:160 senile patients with primary hypertension and acute left cardiac failure were randomly divided into control group(80 cases)and observation group(80 cases). Control group received 12.5 mg captopril, orally,twice to 3 times a day (if patients had taken plenty of diuretic drugs,in low sodium and/or low blood volume,patients with normal or low blood pressure,the initial dose was 6.25 mg,3 times a day). Observation group additionally given 9 g of Wenxin granule,3 times a day. The treatment course for both groups was 4 weeks. SBP,DBP,PP,SDANN,SDNN-Index,RMS-SD,PNN50,improvement of cardiac functions before and after treatment,and incidence of adverse reactions in 2 groups were ob-served. RESULTS:After treatment,the SBP,DBP and PP in 2 groups were significantly lower than before,and observation group was lower than control group,SDNN,SDANN,SDNN-Index、RMSSD and PNN 50 were significantly higher than before,and ob-servation group was higher than control group,the differences were statistically significant(P<0.05). And there was no significant difference in the incidence of adverse reactions(P>0.05). CONCLUSIONS:Based on conventional treatment,wenxin granule can significantly reduce the bloop pressure of senile patients with primary hypertension and acute left cardiac failure,improve cardiac functions and inhibit autonomic disorders,with good safety.

AIM: To study the role of acylation stimula ting protein (ASP) in the differentiation of 3T3-F442A preadipocytes. METHODS: Differentiation of 3T3-F442A preadipocytes was induced by ASP. The morphological changes were observed by Oil-Red O staining and the di fferentiation rate was compared. TG synthesis and TG mass in these cells were al so assayed. DNA synthesis was measured by -TdR incorporation. A typical differentiation inducer, insulin, was used as a positive control to compare thes e results. RESULTS: (1) 3T3-F442A preadipocytes were induced to differentia te by ASP alone. Fat droplets were clearly visible in the cytoplasm of 3T3-F442A cells. The differentiation rate was high (90%), but no significant difference w as observed, compared with that in insulin group (95%). (2) In ASP group, TG syn thesis and TG mass were significantly increased, both of them were higher than t hat in control group (P0.05). CONCLUSION: As a new adipocytes hormone, ASP plays an important biological role in the differentiation of preadipocytes.

Objective To study the cell-cycle specificity of tamoxifen-induced apoptosis in the ER(+) breast cancer cells in vitro and in vivo. Methods ER(+) MCF-7 cell line (in vitro) and primary cultured ER(+) breast cancer cells (in vivo) were treated with tamoxifen, and the cell cycle specificity of cell apoptosis and the apoptotic rate were dertermined by flow cytometry. Results Both MCF-7 and primary cultured breast cancer cells were induced to apoptosis with G 0/G 1 phase specificity by tamoxifen. And the apoptotic rate in MCF-7 was higher than that in primary cultured breast cancer cells. Conclusion Tamoxifen could induced G 0/G 1 phase specific apoptosis in the ER(+) breast cnacer cells, and tamoxifen-induced apoptotic rate was higher in vitro than in vivo.

Objective To detect estrogen receptor and DNA index in breast cancer by flow cytometry. Methods 32 cases of fresh specimens of breast cancer resected by operation were used in this study. Single cells suspension was prepared from those specimens, and estrogen receptor expression was analyzed by flow cytometry. At the same time, the status of ploid and S phase cell ratio were determined. Results Flow cytometry analysis could measure the expression level of estrogen receptor in the fresh breast cancer specimens, which was more sensitive and needed less volume of tumor tissue compared with immuohistochemical method. The information on the status of ploid and S phase cell ratio were simultaneously obtained. Conclusion The detection of estrogen receptor in breast cancers by flow cytometry was more helpful for evaluating prognosis and selecting treatment.

Objective: To assess the immunological effects by orally administering chicken type Ⅱ collagen(CCⅡ) on collagen-induced arthritis(CIA)mice. To assess the effect on producing IL-1 of peritoneal macrophage in adjuvant arthritis rats by orally administering CCⅡ. Methods: Arthritis were induced in Kunming mice by immunization with chicken type Ⅱ collagen with Freund's complete adjuvant, followed by an interperitoneal injection of CCⅡ 3 weeks later.Chicken type Ⅱ collagen was orally administered from 5 days prior to the induction of arthritis to 14 days after inducing arthritis model. The animals were examined visually twice weekly for polyarthritic signs of swollen and erythemic limbs. Quantitation of antibody level of CIA mice was measured by ELISA method. Subpopulations of T lymphocytes in mice were evaluated by flow cytometry method. IL-1 assay was evaluated by ELISA method. Results: Joint swelling was significantly reduced at a dose of 5 μg.kg-1 and 50 μg.kg-1 of CCⅡ, but not at 250 μg.kg-1. The level of anti-collagen antibodies was also reduced at a dose of 5 μg.kg-1 and 50μg.kg-1 (OD value from CIA model control 0.242±0.073 to CCⅡ 5 μg.kg-1 0.123±0.029 and CCⅡ 50 μg.kg-1 0.110±0.075 respectively). Subpopulations of T-lymphocytes were changed by orally administering of CCⅡ, and the ratio of L3T4+/Lyt-2+ was lowered (the ratio from 1.71 of CIA model control to 1.21, 1.51 of administered CⅡ 5 μg.kg-1, 50μg.kg-1 respectively.) after administering CCⅡ. IL-1 level can be reduced (the value from adjuvant arthritis model control 62.8±0.9 to 43.4±1.3, 49.7±0 ng.L-1 administered CⅡ 5 μg.kg-1, 50μg.kg-1 respectively). Conclusion: Arthritis sign in CIA animal model can be suppressed by oral CCⅡ. The effects may be involved by influencing the mechanisms both humoral and cellular immunity. The effects occurred at lower doses of CCⅡ. These results demonstrated the biologic relevance of by-stander suppression associated with oral tolerance, and the potential use of this approach to treat human inflammatory joint diseases.

Objective: To investigate the mechanism of Glytan lowering portal pressure induced by biliary liver fibrosis. Methods: SD male rats, 240-260g weight around, were randomly divided into sham-operation group, model group, propranolol group, Glytan high-dose, middle-dose and low-dose group according to the weight. Portal hypertension was induced by common bile duct ligation in rats. After two and four weeks, measured the portal pressure(PP) of each group, observed the histological changes of liver by HE staining, tested liver function and the concentration of endothelin-1 in systemic circulation and mesenteric circulation radioimmnuoassay. Results: After two and four weeks, portal pressure of model group rats increased significantly. Both Glytan and propranolol can decrease PP after two and four weeks, and the pressure-relief effect was similar between the two drugs. HE staining showed that Glytan can significantly inhibit the formation of collagen, promote the recovery of liver tissue structure; liver function indicated a significant decrease in serum AST, ALT, TBIL and Na+ concentration. In addition, Glytan decreased the concentration of endothelin -1 in systemic circulation, increased it in mesenteric circulation after two weeks. Conclusion: Glytan decrease PP by improving liver function and microcirculation, inhibiting collagen formation and water-sodium retention after long-term therapy, ameliorating hyperdynamic circulation at the early stage.

Objective:To determine the correlation of BCG concentration in Freund complete adjuvant ( FCA) and severity of arthritis during arthritis establishment in DBA 1/j male mice induced by bovine type Ⅱcollagen.Methods:CIA was induced by the im-munization of DBA1/j mice with bovine type Ⅱcollagen and BCG of various concentrations dissolved in FCA.To ascertain the effects administering the collagen booster,CIA-related features(including body weight,clinical scoring of arthritis),TNF-αin serum and the histopathological changes in the spleen and the joints regions were measured.Results:4 mg/ml BCG induced more serious arthritis than 1 mg/ml in DBA1/j mice after collagen exposure.Conclusion:There is a positive correlation of arthritis severity with BCG.Which indicates that selection of adjuvant with suitable BCG concentration could determine pathological outcome in CIA mouse model .
