Objective:To investigate the molecular mechanisms of proliferation and apoptosis by penta-brominated Diphenyl Ethers through regulation of mRNA and protein expression of Bcl-2 and Bax in breast cancer MCF-7 cells.Methods:Human breast cancer MCF-7 cells were grown in DMEM medium,MTT assay was employed to investigate cell proliferation.RT-PCR and immunohistochemistry was performed to determine mRNA and protein expression of Bcl-2 and Bax,Results:Within the range of 1?(10~(-8)～10~(-4))mol/L,5-BDEs stimulated proliferation in MCF-7 cells with a dose-dependent and time-dependent fashion.RT-PCR and immunohistochemistry analyses revealed that treatment with 1?(10~(-8)～10~(-4))mol/L for 72h resulted in increased mRNA and protein expression of Bcl-2 and inhibition of Bax.Conclusion:5-BDE possessed estrogenic activity and could markedly stimulate proliferation in estrogen responsive breast cancer MCF-7 cells.Up-regulation of Bcl-2 mRNA and protein expression was suggested to be involved in this biological effect.

Objective To investigate the effect and function analysis by sulfentanyl in patients with tongue cancer postoperative analgesia.Methods A total of 74 patients with radical resection of tongue cancer in department of anesthesiology with general anesthesia from our hospital were collected, patients or their families signed consent, according to postoperative self-controlled intravenous analgesia drugs divided into experimental group and control group with 37 cases in each group.Patients in control group were treated by fentanyl self-controlled intravenous analgesia;patients in experimental group were treated by sulfentanyl self-controlled intravenous analgesia, determination of the analgesic effect, sedative effect and the changed of vital signs postoperative 2, 4, 8, 12, 24, 48 h,at the same time recorded complications.Results After operation, at different time points analgesic effect and sedative effect were changed in the two groups, the VAS scored of the experimental group was lower than the control group postoperative 2, 4, 8, 12, 24, 48 h time points, the Ramsay Sedation scored of the experimental group was lower than the control group postoperative 2 h, 4 h, 8 h, 12 h time points ( P <0.05 ); the changed of vital signs and adverse reactions between the two groups had no difference within 48 hours ( P >0.05 ) . Conclusion Sulfentanyl in the treatment of patients with radical resection of tongue cancer the analgesic effect and sedative effect are better than fentanyl, has no effect on the vital signs, and the role is security and exact.

OBJECTIVETo investigate the effects of closed reduction and ulna intramedullary nail fixation for the treatment of fresh Monteggia fractures of Bado type I and II in children.

METHODSTwenty-three children patients with Monteggia fracture during July 2010 to September 2013 were treated by closed reduction and ulna intramedullary nail fixaion including 18 boys and 5 girls with an average age of 9.3 years old ranging from 6 to 13 years old. Among them,15 cases were Bado type I and 8 cases were Bado type II. There were 9 cases with radial nerve injury. The operation time,the recovery of nerve injury, the fracture healing and the function of elbow were observed and recorded.

RESULTSAll patients were followed up for 6 to 24 months (12 months on average). All patients were obtained bone healing. According to Anderson standard, at the final follow-up, 20 cases got excellent result, 2 cases got good result, and one case got fair result.

CONCLUSIONTreatment of the fresh Monteggia fractures in children by closed reduction and ulna intramedullary nail fixation has advantages of simple operation, less trauma and good results.

OBJECTIVE: To establishes an HPLC method for determination of the contents of Osthol and Berberine in Kangfuyan effervescent suppository. METHODS: HPLC was carried out on a column of Diamonsil (250 mm?4.6 mm,5 ?m) with mobile phase consisted of acetonitrile-0.2% phosphate acid (52∶48,Lauryl sulfonic acid sodium 0.1 g was contained in every 100 mL) with flow rate at 1 mL?min-1.The detection wavelength was set at 322 nm and the column temperature was set at room temperature. RESULTS: The linear range was 0.019 8～0.396 0 ?g(r=0.999 97) for Osthole versus 0.056 65～1.133 00 ?g(r=0.999 99) for Berberine. The average recoveries of Osthol and Berberine were 101.06% (RSD=1.10%) and 101.88%(RSD=0.98%), respectively. CONCLUSION: This method is simple, accurate and reproducible, and applicable for the quality control of Kangfuyan effervescent suppository.

OBJECTIVE:To survey and evaluate the present situation and trend of the anticancer drugs used in 6 cities of the Yangtse valley METHODS:The anticancer drugs,used in 138 hospitals of 6 cities in the Yangtse basin during the period 1999～2001,were analysed in respect to the cost,sales volume of pharmaceutical enterprises and situation of clinical application RESULTS:The costs of anticancer drugs consumption were 19 460,24 421 and 32 227 million yuan in 1999,2000 and 2001,respectively with an average annual cost of 10 238 yuan per sickbed Some new anticancer drugs derived from nature plants and monoantibodies were going to the clinical practice And gene therapy has been introduced to the treatment of cancer CONCLUSION:The anticancer drug is an important kind of drugs used in hospitals The cost per sickbed was much high and was increasing year by year Furthermore,the anticancer drugs derived from nature plants,monoantibody and the gene therapy will be the predominant measures in the future

OBJECTIVE:To analyze the present situation and trend of the application of antituberculotics in hospitals of 6 cities METHODS:The antituberculotics used in 138 hospitals of 6 cities during the 1999～2001 period were analysed in respect to the cost,sales volume of pharmaceutical enterprises and situation of clinical application RESULTS:The costs of consumption of antituberculotics were 6 227 520,7 204 738 and 7 537 601 yuan in 1999,2000 and 2001 respectively with a rising trend year by year The average annual cost of antituberculotics was 282 yuan per sickbed CONCLUSION:The antituberculotics are fewer in kind and inexpensive in price but they occupy an important place in a hospital and their consumption is unceasingly increasing

Objective To investigate and analysis the prevalence rate of hospital infection and community infection,and to reduce the incidence of hospital infection.Methods First we investigated hospitalized patients in September 9,2013 by two ways which in-clude bedside investigation and reviewing the medical records;and then described the prevalence case of infection and the usage of antimicrobial agent by descriptive approach.Results Seven hundred and seventy patients were investigated with the rate of 100.00%;18 patients were hospital infection cases,the infection rate was 2.34%;most of the hospital infection cases was occur in lower respiratory tract;228 patients were community infection cases.The infection rate was 29.61%;the primary affected areas of community infection were respiratory and gastrointestinal tract;the structure of hospital infection pathogens were almost the same with the community infection,most of them were G- bacteria;186 patients were used antimicrobial agent in that day,the usage rate was 24.16%.Conclusion Promoting the managements of high risk departments and susceptible affected areas,making relevant rules of operation are the focus of our works in the future.
