Objective To study the effect of different cag pathogenicity island in Helicobacter pylori ( Hp ) from Chinese patients and various kinase inhibitors on Hp induced interleukin 8 (IL 8) secretion in Chinese gastric epithelial cells. Method Chinese gastric epithelial cells(MGC 803) were cocultured with Chinese clinical cagA +cagE +, cagA +cagE -,cagA -cagE +,cagA -cagE - Hp in vitro, respectively. At the end of culture, IL 8 protein secretion was assayed by ELISA. The effect of the inhibitor of protein kinase A(PKA), C, G, protein tyrosine kinase(PTK) was analyzed on IL 8 protein secretion in gastric epithelial cells by Hp stimulation. Results cagA +cagE + Hp induced IL 8 protein secretion higher than cagA + cagE - or cagA -cagE + Hp , but cagA -cagE - Hp didn′t increase IL 8 protein secretion in gastric epithelial cells. Further studies with gastric epithelial cell showed that IL 8 protein secretion induced by cagA +cagE + Hp was blocked by the PTK inhibitor herbimycin A but not by PKA inhibitor H7, PKC inhibitor calphostin C, and PKG inhibitor KT5823. Conclusion cagA +cagE + Hp significantly increases IL 8 protein secretion and it depends on PTK activation in gastric epithelial cells.

Objective To investigate the relationshp among Gp Ⅱ b/ⅡⅢ a、CD62p in platelet activation mark-er and high-sensitivity C-reactive protein (hs-CRP) in elderly patients with chronic cor pulmonary exacerbation. Methods The subjects were divided into four groups (42 elderly patients with cor pulmonary exacerbation,42 eld-erly patients with cot pulmonary remission,30 cases of healthy elderly subjects and 30 cases of healthy non-elderly subjects) . The expression of Gp Ⅱ b/Ⅲ a and CD62p were measured with tricolor flow cytometry. Hs-CRP levels were measured by nephelometry and turbidimetry in patients and normal controls. Results Compared with cor pul-monary remission group,healthy elderly group and healthy non-elderly group, the levels of Gp Ⅱ b/Ⅲ a, CD62p and hs-CRP increased significantly in patients with chronic cor pulmonary exacerbation ( all P < 0.001 ). Gp Ⅱ b/Ⅲ a and CD62p results of the elderly patients with cot pulmonary remission were higher than those in healthy elderly subjects (P <0.05) and healthy non-elderly subjects (P < 0. 001 ) . The expressions of both Gp Ⅱ b/Ⅲa and CD62p in healthy elderly subjects were statistically higher than that in healthy non-elderly subjects ( P < 0.05 ). There was a positive con'elation between the Gp Ⅱ b/Ⅲ a、CD62p and hs-CRP in elderly patients with chronic cot pulmonary exac-erbation(r =0.59,P<0.01 ; r=0.54,P<0.01 ). Conclusions The platelet in elderly patients with chronic cot pulmonary exacerbation is overactivated,which is correlated with hs-CRP.

The effects of estradiol and tamoxifen on the proliferation of estrogen receptor positive cells and the relationship between the tamoxifen tolerance and cell origin were investigated. The tissues of human endometrium and breast cancer were randomly selected following dissection for primary cell culture. After the breast cancer cells and endometrial cells were treated with 1 x 10(-8) mol/L estradiol and/or 1 x 10(-6) tamoxifen, 3H-labelled thymine nucleotide was used to trace the kinetics of cell proliferation. There was no significant difference in the inhibition on the human endometrial cells between tamoxifen-treated group (6.3%) and control group (6.4%), but tamoxifen could significantly inhibit the proliferation of the human breast cancer cells (45.84%) as compared with control group (52.72%). Moreover, tamoxifen could significantly stimulate the proliferation of tamoxifen resistant breast cancer cells (9.64%) as compared with control group (6.32%). Estradiol could significantly stimulate the proliferation of all the three kinds of cells as compare with control group. The combined use of estradiol and tamoxifen could inhibit the proliferation of the endometrial cells and breast cancer cells as compared with estradiol used alone, but on the tamoxifen resistant breast cancer cells, they could more significantly stimulate the proliferation than E2. It was concluded that E2 could stimulate the proliferation of these three kinds of cells. However, the inhibitive effects of tamoxifen on the proliferation of these cells were dependent on the estradiol.

Objective To study on the value and safety of early endoscopic retrograde cholangiopan-creatography (ERCP)and endoscopic sphincterotomy (EST) in acute biliary pancreatitis. Methods Ninety-two patients with acute biliary pancreatitis underwent early ERCP (within 72 hours) and received endoscopic therapy (ERCP group). Another 40 patients with acute biliary pancreatitis were treated conservatively without ERCP (control group). The disappearance of abdominal pain, decrease of serum amylase level, the mean days and costs of hospitalization and complications were observed in all patients. Results In ERCP group, all patients were performed EST, stones in 72 choledocholithiasis patients had been removed with net-basket or air pocket. Ten cases of severe acute biliary pancreatitis received endoscopic pancreatic duct stents drainage. Ninety two cases of acute biliary pancreatitis received endoscopic nasal catheter bile drainage. The days of the disappearance of abdominal pain, the decrease of serum amylase levels, the cost of the hospitalization and the days of the hospitalization were significantly shorter in the early ERCP group than in the control group. The mortalities in ERCP and control group were 8. 3% and 33. 3% respectively. Conclusion Early ERCP endoscopic therapy is a safe procedure has the superiorities in lowering the mortality, hospital days and expense.
