Objective To investigate the safety,therapy and prophylactic effect of Omeprazole on stress ulcer in children with epidemic type B encephalitis.Methods Before and after medication,chest X-ray examination was performed.The result of occult blood(OB) was confirm by Colloidal gold assay in stool and/or gastric juice.Based on the result of OB,the patients were divided into therapy group[besides conventional therapy for encephalitis,Cimitidine group and Omeprazole group with positive result OB,was administered with 0.9% normal sodium 100 mL+Cimitidine 20-40 mg/(kg?d),iv,q12 h and normal sodium 100 mL+Omeprazol 0.5-0.8 mg/(kg?d),iv,qd,respectively] and prophylaxis group(Cimitidine group,Omeprazole group and control group,with negative result OB,were administered with same medicines as therapy group,respectively.Except control group being administered only 0.9%NS 100 mL,iv,(q12 h)).The effects of drugs on hemostasis,preventing hemorrhage,and the potential risk of acquired pneumonia result from drugs used were observed.Results In therapy group,the average time of hemostasis in Omeprazole group was obviously shorter than that of in Cimitidine group,there was significant difference between two groups(P0.05).Conclusions Both of the drugs is safety and effect to therapy or prophylaxis for the latent stress ulcer in short term.The effect of Omeprazole is better than those of Cimitidine.Using Cimitidine and Omeprazole,neither therapy nor prophylaxis for stress ulcer increaseds the potential risk of acquired pneumonia in children with epidemic type B encephalitis in this study.

Metformin is the most commonly prescibed drug for type 2 diabetes mellitus as it is inexpensive, safe, and efficient in ameliorating hyperglycemia and hyperinsulinemia. Numerous epidemiological studies indicate that diabetic population is not only at increased risk of cardiovascular complications, but also at substantially higher risk of many forms of malignancies. Meanwhile, epidemiological and clinical observation studies have shown that metformin use reduces risk of cancer in patients with type 2 diabetes mellitus and improves prognosis and survival rate of the cancer patients. Furthermore, metformin has been used for cancer therapy in clinical trials. Thus, metformin is emerging as a new cancer therapy or adjuvant anticancer drugs. This review summarizes recent progress in studies of metformin use and its molecular mechanism.

To improve the accuracy of finite element method used in medicine field, it is necessary to build the finite element model including real structural information of tissues in human body. In this study, an edge extracting method was introduced on CT image of human body, and the method of building the two-dimensional finite element model from the extracted edges was then raised. Using the above methods, a finite element model of human body containing real structural information can be successfully made. The methods were used for many CT images of hospitals and tested to be simple, fast and adaptable. The study makes a good foundation for further finite element analysis based on medicine images.

Objective To investigate the effects of Par-4 gene silence on hydrogen peroxide-induced apoptosis in alveolar epithelial cells. Method The alveolar epithelial cells A549 were cultured and exposed to hydrogen peroxide. The siRNA sequences targeted Par-4 gene was chemically synthesized and transfected to A549 cells with or without the exposure of hydrogen peroxide. The cells were divided into normal control groups, hydrogen peroxide-treated group(The cells were treated with 0. 1 mmol/L hydrogen peroxide), hydrogen peroxide and Par-4-siRNA-treated group(The cells were treated with 0. 1 mmol/L hydrogen peroxide after transfection of Par-4-siRNA), Non-specific DNA sequence transfection control group. The apoptosis of A549 cells was quantified by flow cytometry. The expression of Smac protein was detected by Western blot.Electrophoretic mobility shift assay was applied for evaluating the change of E2F1 DNA binding activity. Relative activity of Caspase-3 was detected by clolorimetric assay. Results The percent of apoptotic cells in hydrogen peroxide and Par-4-siRNA-treated group was (29.7 ± 2.3) %, which was significantly lower than that of hydrogen peroxide-treated group [(54.2 ± 4.1)%, q= 8.91, P ＜ 0.01)]. Par-4 siRNA could significantly suppress the increase of Smac protein, E2F1 DNA binding activity and caspase-3 activity induced by hydrogen peroxide in A549 cells. Conclusions Par-4 gene silence induced by siRNA might inhibit the apoptosis of alveolar epithelial cells, which might be resulted from suppression of the up-regulation of Smac gene expression, E2F1 DNA binding activity and caspase-3 activity.
