AIM: To study the effects of artemisunate on anoikis resistance in human breast cancer cells. METHODS: After breast cancer MCF-7 cells were treated with artemisunate, the growth of anchorage independence of breast cancer MCF-7 cells was examined in soft agar colony formation, and apoptosis of breast cancer were evaluated by terminal deoxynucleatidyl transferase-mediated deoxyuridine triphosphate nick end labeling (TUNEL) and DNA ladder. RESULTS: Artemisunate significantly inhibited the growth of anchorage independence of breast cancer MCF-7 cells in soft agar colon formation in a dose-dependent manner. Artemisunate induced apoptosis in breast cancer cells was conformed by DNA ladder and TUNEL assay, which was in a time-and dose-dependent manner. CONCLUSION: Artemisunate inhibits the growth of anchorage independence of breast cancer MCF-7 cells, which is related to anoikis.

Objective: To investigate into the etiological factor,distribution of syndrome(patterns),pathogenesis features as well as the curative effects of small compound prescriptions of(Traditional) Chinese Medicine(TCM) in the treatment of acute stroke in stroke unit.Methods:(Cases) corresponding to diagnosis standards were randomly divided into control group(102 cases) and treatment group(156 cases).Conventional treatment methods were given to cases in control group.On the base of control group,small compound prescriptions were added to in treatment group,successively 14-21 days.The relation between types and time and TCM scale(TCMS),the NIH stroke scale(NIHSS) and Barthel index(BI) were observed in the two groups.Results: Stroke was age-related,the older,the more stroke patients.Stroke was closely related to hypertension.Ascending hyperactivity of liver yang was main type in the previous three days,this type(decreased) with the time going on.On the contrary,the type of wind phlegm and blood stasis was secondly main type in the previous three days,it increased with the time going on.Types of ascending hyperactivity of liver yang,wind phlegm and blood stasis as well as phlegm heat and constipation covered 95 per cent of all patients in the previous 21days.In the two groups,the mean scale of TCM and NIH decreased,and BI increased after treatment,this statistical difference could also be seen between the two groups.Conclusion: Excessive types are main types in the acute stage of stroke.Types of ascending hyperactivity of liver yang,wind phlegm and blood stasis as well as phlegm heat and constipation are its main types.Transferring of ascending hyperactivity of liver yang into endogenous wind may be trigger of reaction link of wind,fire,phlegm and blood stasis in TCM theory.Small compound prescriptions of TCM aiming to clearing away liver fire to stop wind,to activate blood for removing blood stasis and phlegm,to removing phlegm and heat from discharge can reduce scale of TCM and NIH,increase BI in the treatment of patients in stroke unit,which provide beneficial proofs for evaluation of effects of TCM.

Objective:To evaluate the effect of continuing intervention on prophylactic application of antibiotics in sterile operation in urology department by clinical pharmacist to provide reference for the clinical prophylactic application of antibiotics. Methods:All cases of discharged patients underwent sterile operation in urology department of our hospital from July 2010 to June 2014 were divided into three groups according to the intervention time and methods: non-intervention group(n=141), stage Ⅰ intervention group(n=139), stage Ⅱ intervention group (n=162) and stage Ⅲ intervention group (n=137). The prophylactic application of antibiotics was statistically analyzed. Results:After the continuing intervention, the prophylactic application rate of antibiotics in the three inter-vention groups was decreased significantly from 100% before the intervention respectively to 34. 5%,18. 5% and 14. 6% after the in-tervention (P<0. 01). The rationality rate of prophylactic application was improved significantly from 36. 9% before the intervention respectively to 58. 3%, 63. 3% and 85. 0% after the intervention (P<0. 01). The course of prophylactic application was decreased significantly from (138.2 ±31.6)h respectively to (89.9 ±48.0)h,(72.8 ±32.5)h and(45.1 ±29.5)h (P<0.01) and the post-operative infection rate was decreased from 2. 8% respectively to 2. 1%,1. 8% and 1. 4%. Conclusion:The pharmaceutical interven-tion is feasible and valid to improve the rational prophylactic use of antibiotics in urological surgery.

Objective To analyze the policy support of rural doctors for the essential medicine system,and explore the main influence factors and mechanism affecting the support degree.Methods 621 rural doctors from five cities in Shandong province were subject to a stratified random sampling for a quantitative questionnaire,to build a hypothesis model of policy support of rural doctors,which is verified using factor analysis and path analysis.Results 59.1% of rural doctors support the essential drugs policy.It was found that the essential medicine factor,the factor to influence the practitioner,and the supporting policy factor had a direct impact on policy support of rural doctors,with the effect of 0.305, 0.1 59 and 0.135 respectively;Essential medicine factor and the supporting policy factor indirectly influence the policy support of rural doctors through the factor to influence practitioners,with the effect of 0.065 and 0.032 respectively.Conclusion The essential medicine system needs to emphasize such rationality as the quality,list and pricing of essential medicines;it is imperative for the government to better oversee the purchase and supply of essential drugs,to cater to the interests of rural doctors,to encourage the enforcement of the system,and promote the development of village clinics.

OBJECTIVE:To investigate the effect of clinical pharmacist intervention on prophylactic application of antibiotics in cardiothoracic surgery. METHODS:Medical records of patients underwent cardiothoracic surgery were collected from our hospi-tal during Mar. to Apr. in 2014 (before intervention) and during Jun. to Jul. in 2014 (after intervention). Those were divided into pre-intervention group(n=115)and post-intervention group(n=119). The prophylactic application effect of antibiotics was com-pared before and after intervention. RESULTS:After intervention,the rates of prophylactic application were decreased significantly from 96.5% to 72.3%;the rationality rate of antibiotics selection was improved significantly from 27.9% to 94.2%;The course of prophylactic medication decreased significantly from(5.4±2.8)days to(2.3±1.8)days;the difference had statistical significance before and after intervention(P<0.01). The postoperative infection rate was decreased from 13.0% to 5.9%,the difference had no statistical significance(P=0.074). The average hospitalization time,average drug costs,and average hospitalization expenses were decreased significantly,the difference had statistical significance(P<0.05 or P<0.01). CONCLUSIONS:Clinical pharmacist inter-vention to prophylactic application of antibiotics in cardiothoracic surgery can control the infection effective and guarantee reason-able and safe use of drugs during perioperative period.
