The prevalence and adjusted rate of Mental Retardation(M. R.) were 2.70% and 2.68% in the Qin-Ba Mountain Area in South-Shaanxi; 2.78% and 2.80% in childhood respectivety. These rates were all higher than overall rates in Shaanxi and in It is obvious that the prevalence of M. R. could be reduced by the social-environmental factors such as natural geographic situation, social development level, mean income per capita, mother's schooling, the family relationship with stepmother/stepfather, etc. Reducing prevalence rate of M. R., we need to take the multiple measures and services. It may help the reduction of M. R. prevalence and it is very important to continuously supply iodine salt in these area.

Ohjective To study the indications,clinical effect and complications of hysterectomy so as to im- prove therapeutic effect.Methods The clinical data involving 320 cases of hysterectomy in this hospital from 2000 to 2006 were reviewed,and the pathogenesis,operation mode,curative effect and post-operation complications were analysed.Results Patients who received hysterectomy due to benign gynecologic diseases were cured well cliniclly; those who received hysterectomy due to malignant gynecologic diseases or diseases with the tendency of malignant change were cured well in early stage but the effect was not so satisfactory in later stage.The operation mode was de- cided by considering the pathogenesis and individual difference.Conclusion For benign gynecologic diseases,hys- terectomy can be conducted with good effect after conservative treatment becomes ineffective.For malignant gyneco logic diseases,early treatment will bring good resuh,while late treatment will generate not so satisfactory effect.Indi- cations for operation should be controlled strictly for hysterectomy to guard against complications.

ObjectiveTo study the factors which affect the nurses' implementation of cardiac rehabilitation. MethodsData of 134 nurses who worked or are working in cardiology ward in No.1 and No.2 hospital of China Medical University was analyzed by using descriptive and inferential statistics.ResultsThe overall barriers is at a moderate level. The types of the barriers in order of mean score were no formal rehabilitation program, lack of knowledge, lack of facility, lack of support, and lack of understanding. Conclusions In order to improve the motivation of nurses to implement cardiac rehabilitation nursing, something must be done to improve nursing practice , nursing administration, and nursing education.

Objective To investigate the ontogeny of the islet amyloid polypeptide(IAPP)and explore the relationship IAPP and other classical hormones in human fetal colon and rectum. Methods The localization of IAPP immunoreactive(IR) cells and 5 hydroxytryptamine(5 HT) IR cells in 31 human fetal colon and rectum from 9\|27 weeks of gestation was investigated with immunohistochemical SABC method. Results At 9 weeks of fetal age,a lot of 5 HT IR cells were found in the colon,but IAPP IR cells appeared at 18 weeks.In the rectum,both 5 HT and IAPP IR cells were present at 11 weeks,the number of 5 HT IR cells ascended gradually with fetus aged,reached a peak at 20 weeks and dropped gradually after 21 weeks,while in the whole fetus period,IAPP IR cells appeared fewer and scattered.The co localization of IAPP and 5 HT in some cells of colon and rectum was proved as compared with adjacent sections.Immunohistochemical double staining procedures on the same tissue section also showed that IAPP co existed with 5 HT in some cells.Conclusion\ During the human fetus,IAPP were synthesized and co existed with 5 HT in endocrine cells of the colon and rectum.The possible function on the co existence of IAPP and 5 HT in the colon and rectum of fetal was discussed.

OBJECTIVE: To analyze Technical Barriers to Trade(TBT) of herbal medicines in European Union(EU) und-er The Directive 2004/24/EC and to provide thoughts for the export of traditional Chinese medicines(TCM).METHODS: TheTBT set by European Medicines Evaluation Agency (EMEA) was discussed from aspects of the simplification of restrictions on application, technical standard specifications and authentication system, and documents for registration etc, and some suggestions for the export of TCM were put forward. RESULTS & CONCLUSION: Firstly, Chinese government should strengthen the communication and cooperation with European governments. Secondly, more advanced TCM quality specification should be set up. Thirdly we need to seek for support through multinational investment. Finally we should set up some information consultancy agents and to get access to information related to TBT.

Objective To discuss the advantages of combined use of intravenous indwelling needle and infusion connector joint.Methods 120 cases of children in our hospital receiving chemotherapy through intravenous infusion were randomized into the control group and the experimental group with 60 cases in each group.The control group used heparin cap,after each infusion was completed,with 12.SU/ml 3～5ml of heparin saline pulse-type sealing.The experimental group adopted infusion connector joint,after the infusion completed,3～5 ml normal saline was injected into the joint to flush the blessing sealed tube.The complications rate was calculated in two groups.Results The experimental group and the control group showed differences in the incidence of complications and the patients' approval to nurses.Conclusions Combination of intravenous indwelling needle and infusion connector joint can reduce the complications significantly,and improve patients' approval to nurses.

Obfectives:The purpose of the present study was to compare the effects of different early enteral nutrition formula (containing either MCT/LCT or LCT only) on improving nutritional status of burned patients. Methods:This was a prospective,randomized,single blind and controlled study.Thirty cases of burned patients injured by varous causes with total burn surface area (TBSA) more than 30% were collected and randomized into two groups:①Group F:enteral feeding with Fresubin 750 MCT containing MCT/LCT as fat source,②Group N:enteral feeding with Nutrison,containing only LCT as fat source.All of the thirty patients received isocaloric,isonitrogenous,and isolipidic enteral feeding,with intragastric tube and enteral feeding pump,started within 24 h postburn.The several parameters were observed on postburn day(PBD) 1,4,7 and 10,such as serum concentrations of transferrin and prealbumin and plasma concentrations of prostaglandin E 2(PGE 2) and insulin.Nitrogen in urine per day and excretion of 3 methylhistidine in urine on day 1,7 and 10 postburn were determined. Results:The results showed that the patients of F group had an increased blood concentration of transferrin,prealbumin and insulin,and a decreased plasma concentration of PGE 2.Excretion of nitrogen and 3 methylhistidine in urine was also markedly reduced in patients fed with nutrients containing MCT/LCT compared with LCT. Conclusions :We have shown that an enteral diet containing MCT/LCT can improve the nutrition status of burned patients more effectively.

This research applied the theory of customer satisfaction model in the evaluation of the clinical information system. By means of qualitative and quantitative methods, it made validity and reliability measurement on the measurement tools in use. In addition, it extracted the structure validity of the factor regulating scale via a factor analysis, and developed the scale for clinical information system measurement These efforts provided the hospitals with the useful measurement tool to improve their information system, promoting positive and practical hospital informationziation.

Objective To study the current status of morning blood pressure peak in elderly masked hypertension patients and study the correlation between morning blood pressure peak and cognitive function.Methods A total of 72 elderly masked hypertension patients were selected in this study,.Morning blood pressure peak was measured by ABPM examination.The patients were divided into three groups according to the morning blood pressure peak.Morning blood pressure peak ≤ 30 mmHg were divided into non-Morning blood pressure surge group ( NMS group),morning blood pressure peak ＞30 mmHg were divided into Morning blood pressure surge group ( MS group).The cognitive function scale was determined (MMSE and MoCA).T-test and linear regression analysis were performed.Results MMSE score(27.69±2.04) and MoCA scores(24.85 ± 1.52) in MS group were lower than NMS group (28.87 ± 1.34,26.54± 1.53) ( P ＜0.01 ).MMSE and MoCA scores were negatively correlated with the morning blood pressure peak ( r =- 0.308,- 0.447,P ＜ 0.01 ).Conclusions Elderly masked hypertension patients remained the phenomenon of the morning blood pressure peak,the morning blood pressure peak could lead to cognitive impairment.
