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 the mutations of CLCNKB gene in a family with classic Bartter syndrome. Methods Genetic DNA was extracted from peripheral blood leucocytes of family members.The coding exons and intron exon junctions of CLCNKB gene were amplyfied by PCR and sequenced directly.Fifty unrelated healthy subjects were selected to exclude the possibility of polymorphism. Results A heterozygous(missense)mutation(482T>G,L161R)was detected in the exon 4 of patients.The hetemzygous mutation(L161R)was found in the mother,while no mutation was found in the father of this family.L161R had not been reported and was a novel mutation when referring to literatures and human genomic database home and abroad.Conclusion A new CLCNKB gene mutation(L161R)is identified for the first time.

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 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 investigate the protective effect of theaflavins on thymus injury caused by total body irradiation (TBI).Methods Twenty-five C57BL/6 mice were randomly divided into 5 groups:control group,4 Gy TBI group,4 Gy TBI + 25 mg/kg theaflavins group,4 Gy TBI + 50 mg/kg theaflavins group and 4 Gy TBI + 100 mg/kg theaflavins group.Thymus index and total number of thymocytes were detected at the 14th d post-irradiation to determine the optimal dose of theaflavins.According to this optimal dose,32 C57BL/6 mice were randomly divided into 4 groups:control group,theaflavins group,4 Gy TBI group and 4 Gy TBI + theaflavins group.Thymus histomorphology,CD4CD8 T cell subsets,and reactive oxygen species (ROS) in thymocytes were examined at the 14th d post-irradiation.Results The irradiated thymus exhibited decreased thymus index and total number of thymocytes (P ＜ 0.05),aberrant histomorphology and T cell subsets (P ＜ 0.05),and increased ROS level in thymocytes (P ＜ 0.05).Compared with 4 Gy TBI group,the thymus index and total number of thymocytes were significantly increased in 4 Gy TBI + 50 mg/kg theaflavins group (P ＜ 0.05).The total number of thymocytes was significantly higher in 4 Gy TBI + 50 mg/kg theaflavins group than that in 4 Gy TBI + 25 mg/kg theaflavins group (P ＜ 0.05).Therefore,50 mg/kg theaflavins was chosen as the optimal dose for subsequent experiments.Moreover,the aberrant histomorphology of irradiated thymus was alleviated by theaflavins.A decline in the percentage of CD4-CD8-T cells and an elevation of CD4+CD8-and CD4+CD8+ T cells were found in irradiated mice administered with theaflavins (P ＜ 0.05).Compared with 4 Gy TBI group,the ROS level was significantly decreased in 4 Gy TBI + theaflavins group (P ＜ 0.05).Conclusion Theaflavins exhibits a protective effect on radiation-induced thymus injury.
