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.

Objective:To observe the efficacy of acupuncture plus tuina therapy for insomnia.
Methods:Totally 100 eligible patients were randomized into a treatment group (n=51) and a control group (n=49) by using the random number table. The treatment group was intervened by acupuncture at Baihui (GV 20), Fengchi (GB 20), Wangu (GB 12), Shenting (GV 24), Anmian [Extra, locates at the midpoint between Yiming (EX-HN 14) and Fengchi (GB 20)], and Neiguan (PC 6) plus tuina treatment; the control group was intervened by acupuncture alone. For both groups, the treatment was given once a day, 10 sessions as a treatment course, and the efficacies were evaluated and compared after 3 treatment courses.
Results:Of the 51 subjects in the treatment group, 46 cases completed 3 treatment courses, and 17 cases were cured, 18 cases showed marked efficacy, 7 cases were improved, 4 cases had invalid result, and the total effective rate was 91.3%. Of the 49 subjects in the control group, 46 cases completed 3 treatment courses, and 8 cases were cured, 12 cases showed marked efficacy, 14 cases were improved, 12 cases had invalid result, and the total effective rate was 73.9%. The total effective rate of the treatment group was significantly higher than that of the control group (P<0.05).
Conclusion:Acupuncture plus tuina can calm the mind and activate meridian qi in treating insomnia, and it can produce a more significant efficacy than pure acupuncture treatment.

Objective To explore ladder and compensation system of nurse-staffing which is suitable for the situation of our country.Methods The ladder management and compensation system to nursestaffing of National Health Service (NHS) in UK were given detailed introduction and analysis through the official documents,references and personal study experiences,and summarize its scientific and referenced aspects.Results NHS has formed a set of mature competency-based ladder system,and linked the ladder system to compensation system,made a relative scientific performance appraisal system,realized the scientific competency matches the level,salary changes along with the level model.Conclusions It provides references and thinking to the in-depth reform of public hospitals in our country,and the development of high quality nursing service,as well as the implementation of nursing ladder management and compensation reform.

Objective To evaluate the effiicacy of nasotracheal intubation using blind tracheal intubation device and end-tidal carbon dioxide monitoring technique in patients with difficult airway.Methods Sixty ASA Ⅰ or Ⅱ patients of both sexes,aged 35-60 yr,weighing 55-75 kg,requiring nasotracheal intubation,undergoing selective oral and maxillofacial surgery,were involoved in this study.All of them were expected to have difficuh airway such as mouth opening ＜ 3 cm,neck upward degree ＜ 30° and Mallampati classification Ⅲ or Ⅳ,The patients were randomly divided into 2 groups(n =30):group Ⅰ received tracheal intubation with the blind tracheal intubation device and group H received tracheal intubation with the blind intubation device combined with end-tidal carbon dioxide monitoring technique.The number of successful intubation,the inlubation time and adverse effects during intubation(epistaxis,tachycardia,hypertension and hypoxemia)and after operation(sore throat and hoarseness)were recorded.Results The rate of successful intubation in the two groups was 100％.Tachycardia,hypertension,hypoxemia and hoarseness were not found in the two groups.Compared with group I,the rate of successful intubation at first attempt was significantly increased,the intubation time was significantly shortened,and the incidence of epistaxis and sore throat was decreased in group Ⅱ(P ＜ 0.05).Conclusion The blind intubation device combined with end-tidal carbon dioxide monitoring technique used in diffficult airway can shorten the intubation time,increase the success rate of tracheal intubation,and decrease the occurrence of adverse effects.

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.

Objective To evaluate the prevalence of aspirin resistance in old-aged patients with cerebral infarction and to analyze the mechanisms and clinical predictors of aspirin resistance. Methods 300 old-aged patients with cerebra] infarction were selected and the platelet aggregation ratio was determined by nephelometry with CHRONO-LOG PA-meter. And some information of these patients, such as age, sex, smoking, taking non-steroid anti-inflammatory drug (NSAD)or proton pump inhibitor (PPI), obesity, coronary artery disease (CAD), peripheral vascular disease, hyperpiesia, diabetes and hyperlipemia were recorded. Results 112 cases (37.33%) were aspirin sensitiveness, 108 cases(36.0%) were aspirin semi-resistance and 80 cases (26.67%) were aspirin resistance. These cases were divided into two groups. One was aspirin sensitive (AS) group, which included 112 patients of aspirin sensitiveness. The other was aspirin resistant (AR) group, which consisted of 188 patients of aspirin semi-resistance and aspirin resistance. The prevalence of CAD, hypercho]esteremia and RBC count in AR group was higher than that in AS group The percentage of patients who took NSAD, PPI and smoke in AR group was also higher than that in AS group. Conclusion Aspirin resistance existed in old-aged patients with cerebral infarction to great extent, and which was correlated with CAD, hypercholesteremia, smoking, RBC count, taking NSAD and PPI.
