OBJECTIVE:To evaluate the effect of comprehensive intervention management mode on the use of proton pump inhibitors(PPIs)injection in oncology department of hospital. METHODS:Simple random sampling method was conducted to col-lect 1 457 discharged medical records used PPIs injection in oncology department of our hospital from Jan. 2012 to Dec. 2013(be-fore intervention)and 793 records from Jan. to Dec. 2014(after intervention). The utilization of PPIs injection before and after ad-ministrative intervention,technical intervention and information management was compared. RESULTS:After comprehensive inter-vention,the utilization rate of PPIs injection in oncology department of our hospital decreased from 62.59%(before intervention) to 60.70%,without significant difference(P>0.05). There were significant differences in the proportion of PPIs injection’s con-sumption amount in total medical costs and per capita consumption amount before and after intervention(P<0.05);the utilization rate of Lansoprazole for injection increased from 19.70%(before intervention) to 34.68%,and the Omeprazole for injection de-creased from 34.45%(before intervention)to 25.60%,with significant differences(P<0.05),while there were no significant dif-ferences in the utilization rate of Pantoprazole for injection and Esomeprazole for injection(P>0.05). The proportion of irrational use of PPIs injection decreased from 73.99%(before intervention)to 55.86%,among which,the proportions of no indications of medication,repeated administration and too long duration decreased from 40.01%,17.09% and 26.90%(before intervention)to 32.41%,9.08% and 18.03%,with significant differences(P<0.05),while there was no significant difference in the proportion of inappropriate dose selection before and after intervention (P>0.05). CONCLUSIONS:Comprehensive intervention manage-ment mode can improve the clinical utilization of PPIs injection in oncology department of our hospital to some extent,but the irra-tional use of PPIs injection in our hospital is still not optimistic,which needs further improve intervention to promote its clinical rational use.

Japan has accumulated much mature experience in hospital management, which is worthy of being drawn upon by hospital managers in China. By means of an account of the model of ward rounds by doctors at three levels, the system of academic previews and the system of regular meetings for copying down and reading medical papers in foreign languages in Japanese hospitals and in light of the situation of domestic hospital management, the paper discusses measures for improving the system of ward rounds and scientific research management. The goal is to enhance the medical expertise levels, scientific research capabilities and foreign languages proficiency of medical workers in China so as to deliver better medical and healthcare services to the broad masses of the people.

To prokaryotic express prokaryotically and to purify the efaA protein from Enterococus faecalis so as to provide the basis for the further study on the pathogenesis and clinical sero-diagnosis of endocarditis caused by E.faecalis, efaA gene of E.faecalis was amplified by PCR, the PCR-amplified product was digested with restriction enzymes and cloned into prokaryotic vector pET32a to construct the recombinant plasmid pET30a/efaA. This recombinant plasmid was confirmed by double enzyme digestion with BamhI and Xhol and then subjected to sequencing, and transformed to E.coli BL21 (DE3). Expression of the fusion protein was induced by IPTG, and analyzed by SDS-PAGE and Western blotting. The recombinant fusion protein was purified by His-binding affinity chromatography.It was shown that efaA gene of 943 bp in size was amplified from Enterococus faecalis and the recombinant plasmid pET30a,/ efaA was successfully constructed and expressed in E.coli BL21. The purified product was found to be 34 kDa in molecular weight as demonstrated by SDS-PAGE and Western blotting. It is evident that the efaA protein of E.faecalis can be successfully expressed and purified.

Objective To evaluate the effects of an intervention programme of health education and life style modification on postmenopausal osteoporosis women. Methods A total of 120 postmenopausal osteoporosis women were enrolled in this one-year randomized controlled follow-up study and assigned to the intervention group ( Group A, n = 60) or the control group ( Group B, n = 60). Both groups were treated with alendronate sodium. In Group A, education program was performed once a season in the form of face-to-face consultation or group session. In Group B, no additional intervention was used. The primary outcome was patients' compliance in follow-up. The secondary outcomes were change in bone mineral density (BMD).BMD was measured by dual-X-ray absorptiometry (DXA) on lumbar spine and hip at baseline and 12 months after the intervention. Results After one-year intervention,51 subjects in Group A and 38 in Group B completed the follow-up. Groups A showed better compliance. BMD on lumbar spine and hip was significantly increased in both groups when compared with baseline. The changes of BMD on lumbar (0.042+0.067 vs 0.026±0.070,P=0. O29) or Words region (0.029 +0. 129 vs 0.023±0. 143,P=0. 041 ) showed statistical significance between the two groups. Conclusion For alendronate sodium treatment, health management ensures the effectiveness of the therapy and improves the compliance of the patients.

Objective To observe the effect of treatment of the diabetide foot with the fresh skin of the bufo bufo gargarizans cantor. Methods 42 diabetic foot patients were randomized into the control group and the treatment group with 21 patients in each. In the control group the patients were treated with disinfection routinely and dressing changing. In the treatment group the patients were treated with the fresh skin of the bufo bufo gargarizans cantor covering the infected feet after routine disinfection treatment. The treatment effect, the healing time and the length of antibiotics treatment course were compared between the two groups. Results The treatment effect of the treatment group was 100.00%, significantly higher than 80.95% of the control group. The healing time of the treatment group was (9.05 ±4.09) days, shorter than (17.41±4.20)days of the control group. The length of the antibiotics treatment course of the treatment group was(9.33±4.73)days, shorter than (17.10±4.83) days of the control group. Conclusions The fresh skin of the bufo bufo gargarizans cantor can improve the recovery rate, shorten the healing time and the length of the antibiotics treatment course by covering the infected feet.

BACKGROUND: Child neglect is one of the most important aspects of child abuse and has become a serious problem influencing children's development all over the world. Therefore, it is necessary to nderstand the current conditions and influential factors of child neglect and establish effective evaluation methods in China.OBJECTIVE: To investigate the current conditions and influential factors of urban child neglect in Suzhou city.DESIGN: A comparative analysis of sampling survey.SETTING: Department of Children's Health Care, Soochow University Affiliated Children's Hospital.PARTICIPANTS: This study was conducted in one public kindergarten and two private kindergartens of urban areas in Suzhou city between March and October 2003. Totally 370 children (196 boys and 174 girls) aged between 4 to 6 years old without obvious physical and mental diseases were voluntarily investigated, and they had been living with the person that answered the questionnaire regarding to child neglect in China in the recent 1 year. METHODS: Questionnaire regarding to child neglect in China was sent to each volunteer.he questionnaire evaluates the current conditions of child neglect by 20 items of 5 aspects including physical care (buy fruit for child, consider the nutritional need of child, care about the body height and body mass of child), emotional care (chat with child, play and tour with child, encourage child to do the things whatever they can, listen to what the child feels, introduce the child to the guests when they come to your home, let him or her stop immediately when child cries, care about the activities in kindergarten), education care (buy books for child, tell stories to child, recognize and correct the bad behavior of child, answer the questions asked by child seriously), safety care (protections against fire and electricity at home, warn child against matches, knives and other sharp things, teach child how to cross the road) and health care (prepare the common medicine for child at home, urge child to brush teeth, correct the bad posture). The volunteers were asked to answer each question objectively according to the conditions of child within the recent 1 year, and each question should be answered by selecting only one choice (never, occasionally, usually, always), and anyone should not be omitted. Meanwhile,the educational background and occupation of the parents were also investigated.MAIN OUTCOME MEASURES: The general status of child neglect and the effects of different family educational background and occupation of parents on child neglect were observed. RESULTS: Totally 370 questionnaires were sent out, and 370 qualified ones were recollected, the effective rate was 100%. ① In Suzhou city, the children were given better regards and good care in the aspects of education, medicine and safety, but neglects on children's physical and mental care still exists in a few families. ② Families of different educational background could think highly of the medical care, safety and psychical care of children, but neglects on education and emotional development more commonly existed in the families with the educational background under university. ③ All the families with different occupation could think highly of the medical care, safety and physical care of the children, but education and emotional development were better in the cadre families than in the ordinary families.CONCLUSION: In Suzhou city, the children are given better regards and good care in the aspects of education, medicine and safety, but some bad manifestations of child neglect exist in education and emotion, which are associated with the educational background and occupation of the parents.Further studies about the evaluation, prevention and intervention are needed for child neglect in China.
