2.ifferentiation inducing effect of Bifidobacterial surface molecules on human colonic cancer cells
Chinese Journal of Microbiology and Immunology 2001;21(2):186-190
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.

Chinese Journal of Practical Nursing 2012;28(26):68-72
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.
4.Effect of femoral offset on hip joint function reconstruction after arthroplasty in femoral neck fractures
Chinese Journal of Orthopaedic Trauma 2008;10(8):711-714
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.
5.Mechanism of psoriasis generation in animal models.
Acta Pharmaceutica Sinica 2013;48(6):809-13
Psoriasis is a chronic inflammatory disease related to genome-wide and surroundings, it is important to develop a suitable animal model to research psoriasis pathogenesis and evolve pharmacotherapeutics. With the development of transgenetic technology in the past few years, psoriasis virulence gene animal model become a hotspot. Research of animal model of human psoriasis genes is reviewed in the paper.
6.Investigation of Residents’Perceptions for Pharmaceutical Care When Purchasing OTC Drugs in Yinchuan
China Pharmacy 2016;27(30):4197-4199
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.

The long term efficacy of the stent is in progress.
8.Multiple ultrasonographic indexes in diagnosis of unruptured ectopic pregnancy
Chinese Journal of Medical Imaging Technology 2010;26(2):307-309
Objective To evaluate the methods for improving diagnostic ratio of unruptured ectopic pregnancy with ultrasonography. Methods A total of 139 patients of small adnexal cysts with thick wall were predicted respectively with sonographic indexes. All patients (61 with unruptured ectopic pregnancy and 78 with small corpusluteum) were confirmed postoperatively or with long-term follow up, and the results were compared. Results The diagnostic sensitivity of with hyperecho or isoecho compared with endometrium, hyperecho compared with ovarian tissue, adnexal cyst without small follicle around was 86.89%, 93.44% and 96.72%, and the specificity of three predictors was 93.59%, 85.90% and 70.51%, respectively. Two sonographic indexes together had a sensitivity of 98.36% and a specificity of 94.87% for diagnosing ectopic pregnancy. Conclusion Observing the relation of adnexal cyst and ovarian and the echogenic of cyst wall are specific and sensitive for the diagnosis of ectopic pregnancy.
