Objective:To evaluate the antileukemic activity and side effects of topotecan in patients with refractory and relapsed acute myelogenous leukemia(AML).Method:12cases of refractory and relapsed AML were treated with topotecan combined with chemotherapy,8 accepted 1 course,and the others accepted 2 courses.Result:4 patients achieved complete remission.3 had partial remission.The total response rate was 58%.The main side effect was myelosuppression.Conclusion:The topotecan-based induction therapy has antileukemic effect in some patients with refractory and relapsed AML.

Objective　To investigate the direct antitumor effect of several surface molecules of Bifidobacterium bifidum 1101 such as whole peptidoglycan (WPG), lipoteichoic acid (LTA), and polysaccharides (PS) on human colonic adenocarcinoma cell line LoVo. Methods　MTT assay and flow cytometry (FCM) were used to evaluate the effect of Bifidobacterial surface molecules on the growth of LoVo cells. Morphological study, fluorescent polarimetry and differentiation-specific enzyme analysis were used to determine whether LTA treatment could induce the differentiation of the cells. Results　LTA but not WPG or PS significantly inhibited the proliferation of LoVo cells in a dose and time dependent manner. Cell cycle analysis by FCM revealed that LTA induced changes in cycle distribution resulting in G0/G1 phase commitment. Morphological alterations observed by light and electron microscopy indicated maturity of cytoplasm and nucleus following treatment by 50μg/ml of LTA. Membrane fluidity was also altered, and intestinal alkaline phosphatase specific for the differentiation of LoVo cells roused dramatically during culture in LTA. It was further found that LTA elevated ［Ca2+］i which resulted from Ca2+ influx instead of the release of stored calcium. Conclusion　These observations indicated that LTA was able to inhibit the growth of LoVo cells and induce the differentiation of the cells. Calcium influx may play an important role in this process.

ObjectiveTo evaluate the application effect of clinical pathways in hospitalized inguinal hernia patients by using the Meta- analysis. MethodsPublished randomized controlled trials (RCT)in hospitalized inguinal hernia patients were searched and screened in CNKI、VIP、CBMdisc and Wanfang datebase under present standards.The quality of the included studies were evaluated and statistically analyzed by RevMan5.0 software. ResultsTotally 16 literatures including 1649 cases were eligible to the criteria (816 in clinical nursing pathways group and 833 in the traditional health education group)altogether.The Meta-analysis showed there were significant difference between the clinical pathway group and the traditional health education group in grasp of health knowledge,rate of patients,satisfaction degree,length of hospital stay and hospitalization expenses. ConclusionsClinical pathways is superior compared with the traditional health education for hospitalized inguinal hernia patients.

Objective To study the effect of femoral offset reconstruction ON the Harris hip score and the hip ROM (range of motion) after artificial hip replacement in femoral neck fractures. Methods Follow-ups were conducted for 47 patients who had undergone artificial hip replacements for their unilateral femoral neck fractures. We took X-ray pictures to compare the femoral offsets at the affected and unaffected hips. The operated hips were evaluated by the Harris hip score. Statistical analyses were performed with SPSS l2.0 software. Results The Harris hip score of the operated hip was positively related to femoral offset reconstruction(t=7.25,P＜0.001).There was a significant and positive correlation between femoral offset and the hip abductor ROM(r=0.80,P＜0.001).The rate of femoral offset reconstruction had no significant difference between total hip arthroplasty and bipolar hip arthroplasty (χ2=0,P＞0.05).Conclusions Reconstruction of femoral offset after artificial hip replacement in the femoral neck fractures can improve funetional recovery and ROM of the hip. Femoral offset reconstruction is uncorrelated to the selection of total hip arthroplasty or bipolar hip arthroplasty.

OBJECTIVE:To explore consumers’perceptions for pharmaceutical care by community pharmacist when purchas-ing OTC drugs. METHODS:Semi-structured interview was conducted for 100 consumers who were recruited in Xingqing District, Jinfeng District and Xixia District of Yinchuan,Ningxia Hui Autonomous Region,their expection for pharmaceutical care by com-munity pharmacists was summarized. RESULTS:Totally 100 residents were interriewed,and 97 completed a full interview with ef-fective interview rate of 97%. Consumers still did not clearly on distinguishing the OTC drugs. The majority of consumers chosen OTC drugs were based on experience and brand,a handful of consumers were under the guidance of community pharmacists. Con-sumers were most concerned about the efficacy,adverse reactions and drug quality in using OTC drugs. Most consumers were not satisfied with the pharmaceutical care in purchasing OTC drugs. Nevertheless,due to a lack of medicine knowledge,consumer had a great demand for pharmaceutical care and willingness to accept it. Low professional level of community pharmacist and staff in current community pharmacy and lack of effective communication between pharmacist and consumer were the obstacles of develop-ing pharmaceutical care. CONCLUSIONS:Because of their distrust on competence of community pharmacist,consumers seek less pharmaceutical care of OTC drugs at community pharmacy though they had expectations on pharmaceutical care of OTC drugs by community pharmacist. Consumers’rely on self-choice of drugs make them exposed to more drug risks.

In recent years,thyroid cancer incidence increased year by year,after the effective prevention of iodine deficiency disorders in many countries,which caused widespread attention in academia.Whether is this increasing trend related to the implementation of policy of iodized salt in many countries? Currently,the association between iodine intake and thyroid cancer is unclear.This review article describes the metabolic and nutritional status of iodine,and the epidemiology of thyroid cancer,and further elaborates the relationship and the pathogenesis of iodine and thyroid cancer.

Objective:In the performance appraisal of public hospitals,the lack of detailed degree of personalized appraisal,inadequate attention of hospital leaderships and unreasonable performance appraisal indexes were analyzed to provide measurement.Methods:Using the equity theory to conduct specific analysis on the problem.Results:To promote the stable and sustainable development of public hospitals,it mobilized the enthusiasm,initiative and creativity of the employees.Conclusion:It needed to create more economic and social benefits and enhance the core competitiveness of the hospital.

Background and purpose:The mutation of BRCA1 gene is widely acknowledged to be related to the incidence of triple-negative breast cancer (TNBC). The aim of this study was to investigate the association between TNBC and single nucleotide polymorphisms (SNPs) of BRCA1-associated genes. Methods:This study investigated the associations between the BRCA1-A complex genes and risk of developing TNBC in a case-control study of Chinese Han Women population including 414 patients with TNBC and 354 cancer-free controls diagnosed in the Fudan University Shanghai Cancer Center during 2008-2011. This study also detected 37 common variants in Abraxas, BRE, Rap80, NBA1 and BRCC36 genes encoding the BRCA1-A complex and evaluated their genetic susceptibility to the risk of TNBC. An additional cohort with 652 other types of breast cancer (non-TNBC) cases and 890 controls were used to investigate the associations between TNBC-speciifc SNPs genotype and non-TNBCs susceptibility. Results:This study found that rs7250266 in the promoter region of NBA1 confers a decreased risk to TNBC (P<0.01). Compared with CC genotype, women with the GC genotype (OR=0.70, 95%CI:0.51-0.97) and GG genotype (OR=0.48, 95%CI:0.21-1.07) had a lower risk of developing TNBC (P=0.03). In addition, the haplotypes containing two polymorphisms rs7250266 and rs2278256 were associated with a lower chance of TNBC development. In the second part of the study, the result showed that there was no difference in rs7250266 expression between non-TNBC and normal people (0.19 vs 0.18, P=0.85).Conclusion:Genetic variants in NBA1 may be an important genetic determinant of TNBC susceptibility in Chinese women.
