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 study the influence of hierarchical model on the professional attitude and quality improvement of nurses and supply references for the apphcation of hierarchical model.Methods 310 nurses were divided into the control group(158 cases)and the practice group(152 cgses).The practice group adopted hierarchical model while the control group did not.Investigation was carried out in 15 aspects such as training requirement,choosing of nursing posts and departure intention,etc.Results The nursing teaching pest and nursing management post in the aspect of post requirement between the two groups had no statistical difference(P＞0.05),but statistical difference existed in other items(P＜0.05).In the aspect of training requirement evident difference existed in two groups(P＜0.05).Conclusion Application of hierarchical model proved to be a pivotal method to improve the professional passion and loyalty of nurses.

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 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.

Objective To discuss the application value of shear wave elastography (SWE) and superb microvascular imaging (SMI) in pathological grading of breast invasive ductal carcinoma (IDC).MethodsSixty patients with breast tumor were selected,which were totally 64 lesions.Before operation,SWE and SMI pattern were started to detect the lesions.And images in SWE and SMI pattern were saved.All lesions were proved to be IDC and pathological gradings were got according to the pathological result.The mean of Young′s modulus(AveT1) and maximum of Young′s modulus(AveT2) were recorded in SWE pattern,and degree of blood was recorded in SMI pattern followed Adler′s grading standard.Then differences of AveT1,AveT2 and degree of blood in different pathological grading of invasive ductal carcinoma were evaluated.Results ①In pathological grading 1 group,the average of AveT1 was (62.1±10.4)kPa,and the average of AveT2 was (93.0±20.1)kPa.In pathological grading 2 group,the average of AveT1 was (79.8±8.6)kPa,and the average of AveT2 was (120.6±18.7)kPa.In pathological grading 3 group,the average of AveT1 was (92.6±12.1)kPa,and the average of AveT2 was (137.3±21.5)kPa.The AveT1 and AveT2 were gradually growing with higher pathological grading of breast invasive ductal carcinoma,which were statistically significant (P<0.05).②In pathological grading 1 group,there were 7 cases in the degree of blood 0-Ⅰ and 14 in the degree of blood Ⅱ-Ⅲ.In pathological grading 2 group,there were 3 cases in the degree of blood 0-Ⅰ and 18 cases in the degree of blood Ⅱ-Ⅲ.In pathological grading 3 group,there were only 1 case in the degree of blood 0-Ⅰ and 21 cases in the degree of blood Ⅱ-Ⅲ.There were more lesions of rich blood with higher pathological grading of breast invasive ductal carcinoma,which was statistically significant (P<0.05).Conclusions There are differences of elastography and degree of blood in different pathological grading of breast invasive ductal carcinoma,SWE and SMI can prompt pathological grading and provide important clinical reference value.
