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.

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.

Objective To observe the protein expression of grow thassociated protein-43 (GAP-43) in mid-brain ventral tegmental area in morphine withdrawal rats at different time, and to evaluate the effect of GAP-43 on morphine withdrawal memory. Methods Rat models of morphine dependent 1 week, 2 weeks and 4 weeks were established by morphine hydrochloride intraperitoneal injection with increasing doses to establish natural withdrawal. The protein expression of GAP-43 in midbrain ventral tegmental area was observed by im munohistochemical staining and the results were analyzed by Im age-Pro Plus 5.1 im-age analysis system . Results With prolongation of dependent time, the expression of GAP-43 was de-creased then increased in midbrain ventral tegmental area . Conclusion GAP-43 could play arole in morphine withdrawal memory in midbrain ventral tegmental area.

Objective To evaluate the effects of hydroxyapatite (HA) extensively-coated prosthesis on elderly patients undergoing hip arthroplasty.Methods From February 1997 to May 1999,96 patients Were treated with hydroxyapatite (HA) coated prosthesis and followed up for their hip arthroplasty.Their results were studied clinically and roentgengraphically to evaluate chiefly their Harris scores,complications and thigh pain.The survival of prosthesis was evaluated according to Kaplan-Meier methods.Results The 60 cases were followed up for eight years on average(range,sevon to nine years).Their mean Harris scores were improved from 42 preoperatively to 90 postoperatively.Fifty-eihgt cases felt no pain at their hip,but two did at their thigh.No radiolucent lines were observed.All the prostheses achieved bony stabilization and remolding.Conclusions HA coated prosthesis can achieve fine fixation,because it helps bone conduction,resists axial force and torsion,and reduces operative risks.

Objective To report the experiences in the endovascular embolization treatment of intracranial aneurysm. Methods A total of 29 patients with intracranial aneurism were treated with Gugliemi detachable coils(GDC). Results Complete occlusion was found in 15 cases, 90% occlusion in 12 and 80% in 2. Three patients had different degrees of headache. The coil escaping from the sac of the aneurysm and suspending in the parent artery of the aneurysm was seen in 1 patient. Two patients died: one was due to disruption of aneurysm and another severe bleeding in digestive tube. Conclusion Endovascular embolization of intracranial aneurysm is a minimally traumatic, safe and effective method for the treatment of intracranial aneurysm. GDC system is of easy operation, high safety and low incidence of complications.

Objeetive To explore the effectiveness of early warning assessment and management for maternity on perinatal outcomes.Methods From January 1,2013,a cohort prospective study was conducted on 49 261 pregnant women who registered initially at 6-13 gestational weeks and were followed up at 246 community health centers from 17 districts or counties of Shanghai.The first screening was conducted in community health centers for gestational age verification,medical history collection and physical examination.The pregnant women would be marked as green alert if all of the above three indices were normal.A woman would be transferred to level two or above hospitals if the first screening results were abnormal and the early warning signs were divided into five categories,including green alert (normal),red alert (complicated with sever mobility and complications during pregnancy),orange alert (complicated with sever mobility and complications during pregnancy,but not as severe as that of red alert),purple alert (concomitant communicable diseases during pregnancy),yellow alert (complicated with milder mobility and complications during pregnancy compared with that of red alert).The low risk pregnancy referred to yellow alert,and the high risk ones referred to orange,red or purple alert.We offered corresponding management and follow-up program for women with different warning signs,and analyzed the in-process indices such as screening-transport time,transport-diagnosis time,diagnosis-feedback time,feedback-initial-follow-up time,times of follow-up and regular or irregular follow-up.The association between in-process indices and perinatal outcomes (women with severe diseases during pregnancy and delivery,maternal mortality,preterm and low birth weight children and neonatal mortality) in both low and high risk pregnant women were analyzed using logistic regression model.Results Out of the 49 261 pregnant women,10 485(21.28％) were positive in the first screening and 38 776 (78.72％) were negative.For early warning classification,36 250(73.59％) were classified as green alert,12 277(24.92％) as yellow alert,625(1.27％) as orange alert,8(0.02％) as red alert,and 101(0.21％) as purple alert.The regular follow-up rate for low risk pregnant women was 82.7％(10 153/12 277),and that of high risk women was 74.1％(544/734).Prolonged feedback-initial-follow-up time increased the risk of maternal mortality (OR=1.051,95％CI:1.015-1.088,P=0.008) among low and high risk pregnant women.The increased times of follow-up for risk pregnancies decreased the occurrence of critical illed complications (OR=0.851,95％CI:0.725-0.999,P=0.049) and maternal mortality (OR=0.534,95％CI:0.307 0.930,P=0.014).Prolonged diagnosis-feedback time increased the risk of preterm birth (OR=l.009,95％CI:1.004-1.015,P=0.000).Prolonged feedback-initial-follow-up time increased the risk of neonatal mortality (OR=1.019,95％CI:1.001-1.038,P=0.045).However,the increase of followup times decreased the risk of preterm birth (OR=0.803,95％CI:0.762-0.847,P＜0.001),low-birth weight (OR=0.882,95％ CI:0.775-0.873,P＜0.001) and neonatal mortality (OR=0.653,95％CI:0.543-0.785,P＜0.001),so did regular follow-up (OR=0.432,95％CI:0.353-0.528;OR=0.494,95％CI:0.392-0.621;OR=0.226,95％CI:0.117-0.435;all P＜0.001).Conclusions The system of early warning assessment and management for pregnancy is effective on perinatal outcomes to some in both low and high risk gravidas extend and is worthwhile to be generalized and to form long-term mechanism.

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.

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.
