1.AFFECTING FACTORS OF THE PREVALENCE OF MENTAL RETARDATION IN THE QIN-BA MOUNTAIN AREA IN SOUTH- SHAANXI(1987)
Journal of Xi'an Jiaotong University(Medical Sciences) 1981;0(03):-
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.
3.Clinical analysis of 320 cases of hysterectomy
Chinese Journal of Primary Medicine and Pharmacy 2006;0(07):-
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.
4.An information system evaluation tool built with customer satisfaction model theory
Chinese Journal of Hospital Administration 2010;26(5):361-364
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.
5.A method to estimate the short-term fractal dimension of heart rate variability based on wavelet transform.
Journal of Biomedical Engineering 2006;23(5):981-985
A new method of calculating fractal dimension of short-term heart rate variability signals is presented. The method is based on wavelet transform and filter banks. The implementation of the method is: First of all we pick-up the fractal component from HRV signals using wavelet transform. Next, we estimate the power spectrum distribution of fractal component using auto-regressive model, and we estimate parameter 7 using the least square method. Finally according to formula D = 2- (gamma-1)/2 estimate fractal dimension of HRV signal. To validate the stability and reliability of the proposed method, using fractional brown movement simulate 24 fractal signals that fractal value is 1.6 to validate, the result shows that the method has stability and reliability.

8.Hemophilia B replacement therapy drugs.
Chinese Journal of Biotechnology 2016;32(2):164-171
Hemophilia B is an X chromosome linked hereditary hemorrhagic disease, which is caused by the lose function mutation of factor IX (FIX), and significantly affects the patients' lifespan and life quality. The severity of hemophilia B depends on the FIX level in the plasma. By referring to the relevant literatures, we reviewed and summarized hemophilia B replacement therapies. Specifically, we focus on recombinant factor IX products on the market and those in the pipeline, especially on the long-acting factor IX drugs, to provide the basis for researches of new hemophilia B drugs.

9.Efficacy of nasotracheal intubation using blind tracheal intubation device combined with end-tidal carbon dioxide monitoring technique in patients with difficult airway
Chinese Journal of Anesthesiology 2012;32(5):579-581
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.
10.The correlation of morning blood pressure peak with cognitive function in elderly masked hypertension patients
Journal of Chinese Physician 2011;13(10):1353-1355
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.
