Objective To investigate the change of apoptosis and drug resistance after multiple thermotherapy On the HepG2 Cell. Methods After HepG2 cell were treaded by ten repeated cycles of exposure at 43 degree C for 80 minutes twice a day，the sensibility of HepG2 cell to Adfiamyein was analyzed by MTr assay.The apoptosis Was detected by kit，and the expression of Bcl-2 or Bax protein and mRNA were detected by immunohistochemical method and RT-PCR respective.Results The drug resistance to Adfiamycin Was gained by HepG2 cell after multiple thermotherapy.The rate of apoptosis was decreased，the expression of Bcl一2 protein and mRNA Was strengthened，and the ratio of Bcl-2/Bax increased.Conclusions The resistance of heated HepG2 cell to chemotherapeutics Was related with the decreased rate of apoptosis，overexpression of Bcl-2 protein and mRNA，and increased ratio of Bcl-2/Bax.

Objective To investigate therapeutic effect and mechanism of hyperbaric oxygen and ulinastatin respectively or combinatively used to treat acute necrotizing pancreatitis (ANP). Methods One hundred and twenty SD rats were divided into 6 groups randomly: group of normal control, group receiving sham operation, group of untreated acute necrotizing pancreatitis (ANP group), group of acute necrotizing pancreatitis treated with hyperbaric oxygen (HBO group), group of acute necrotizing pancreatitis treated with ulinastatin (ULT group), and group of acute necrotizing pancreatitis treated with combined hyperbaric oxygen and ulinastatin (HBO+ULT group). The rat model of acute necrotizing pancreatitis was established according to Aho HJ et al. Concentrations of amylase, TNF?, TXB-2 and 6-keto-PGF- 1? in blood were measured through ELISA or radioimmunoassay. Changes of pancreatic histopathology were investigated. SPSS 10.0 was used in statistical analysis. Results The concentrations of amylase, TNF?, TXB-2 in the ANP-treated groups were significantly lower than those of ANP group (P

Objective To investigate the expression change of ghtathione S-transferase π(GSTπ)protein and mRNA in the HepG2 cell after multiple thermotherapy.Methods HepG2 cells were treaded by ten repeated cycles of exposure at 43 degree C for 80 minutes twice a day，the sensibility of HepG2 cell to Adriamycin was analyzed by MTr assay，and the expression of QSTπprotein and mRNA were detected by immunohistochemical method and RT-PCR.Results The drug resistance to Adriamycin was gained by HepG2 cells after multiple thermotherapy，and the expression of GSTπ protein and mRNA wag strengthened.Conclusions The resistance of heated HepG2 cells to chemotherapeutics was concerned with overexpression of GSTπ protein and mRNA.

renal dysfunction.Logisitic regression showed that cardiovascular disease and hypoalbuminemia were correlated with perioperative death rate significantly. Conclusions Improving the perioperative management is very important for lowering the perioperative mortality in elderly patients with digestive tract disease.

OBJECTIVE: To study the expression of intedeukin-5 (IL-5) mRNA and protein in Nasal polyps and in the inferior turbinate, and to explore the relationship between the expression and the Clinical features. METHOD: Real time fluorescent quantitative PCR(RT-qPCR) and immunohistochemical staining were used to detect the expression of intedeukin-5 (IL-5) mRNA and protein in nasal polyps of 24 cases and in inferior turbinate of 15 cases. RESULT: The expression of IL-5 mRNA in Nasal polyps was 7.52 times higher than that in the inferior turbinate (P < 0.01). The expression rate of IL-5 protein in Nasal polyps was 79.17%, significantly higher than that in the inferior turbinate (26.67%) (chi2 = 10.52, P < 0.01). The differece of expression of IL-5 mRNA was not associated with the sexual distinction, unilateral or bilateral nasal polyps and primary or recurrent nasal polyps (P > 0.01), but was associated with the single or multiple nasal polyps, nasal polyps with or without allergic rhinitis and/or asthma. The differece of expression of IL-5 protein was not associated with the sexual distinction, unilateral or bilateral nasal polyps, primary or recurrent nasal polyps, nasal polyps with or without allergic rhinitis and/or asthma, but was associated with the single and multiple nasal polyps. CONCLUSION The high expression of IL-5 mRNA and protein is closely related with the formation edema and development of nasal polyps. Some clinical features of Nasal polyps related to the expression level of IL-5 in nasal polyps.

Objective To study the effect of hyperbaric oxygen(HBO) treatment on plasma endotoxin,sCD14 and plasma endotoxin inactivation capacity(EIC) in acute necrotizing pancreatitis(ANP) in rats and its possible mechanism.Methods SD rats were randomly divided into control group,sham operation group,ANP group and ANP+HBO group.Rat ANP models were made by retrograde injection of 3.5% sodium(taurocholate)(2.5mL/kg) into the pancreatic duct.Thirty minues after models had been made,ANP+HBO group was treated by hyperbaric oxygen for 2h.At 3h,6h,and 10h after establishment of rat models,the plasma endotoxin,sCD14,EIC,TXB_2 and 6-K-PGF_(1a) leves were determined in each group.Results At 3h and 6 h after rat models were established,the levels of endotoxin,sCD14,and TXB_2 in ANP+HBO group were significantly lower than those in ANP group(P

Objective To investigate the Relationship between the CYP2C19 polymorphism and the efficacy of triple therapy with lansoprazole on Helicobacter pylori infection. Methods 125 elderly patients diagnosed with H.pylori infection were treated with triple therapy. Polymorphism of CYP2C19 was measured by AS-PCR. 105 young patients were selected as control group. The relationship between the polymorphism and eradication rate were analyzed. Results Among the 125 patients,eradication rate of extensive metabolizer group,internal metabolizer group and poor metabolizer groups was 85.29%,76%and 89.39%, respectively. There was no significant difference between groups (P > 0.05). Eradication rate showed no difference between experimental and control group either (P>0.05)(P>0.05). Conclusion The results suggests that the CYP2C19 polymorphism has no correlation with the eradication rate of Helicobacter pylori infection by triple therapy with lansoprazole in elderly patients.
