After the reading behaviors ( reading altitude, reading frequency, reading habits and reading types) of 141 students in medical school were investigated and analyzed, the efficiencies of literature retrieval teaching in classroom were summarized, and the future direction was proposed.

Objective To explore the risk factors analysis of patients with hemorrhagic stroke in Zhongshan district of Dalian city in order to providing the Corresponding intervention measures.Methods From Oct 2010 to Aug 2013,183 cases of patients with hemorrhagic stroke(age ＞ 60 years old) and 158 cases healthy physical people in Zhongshan Hospital Affiliated to Dalian University were served as observation group and control group.Clinical information and life habit of two groups were recorded,the height and weight were measured,body mess index (BMI) was calculated,blood lipid level and plasma fiber protein level were detected.Results The rate of male,age ＞70 years,BMI index ≥25 kg/m2,smoking,history of hypertension,TG ≥ 1.7 mmol/L,TC ≥ 5.7 mmol/L,fibrinogen ＜ 4.0 g/L in observation group were 68.85 ％ (126/183),65.03％ (119/183),61.75％ (113/183),77.05％ (141/183),32.24％ (59/183),51.37％ (94/183),62.30％ (114/183),68.31％ (125/183) respectively,higher than those of control group (51.90％ (82/158),44.94％ (71/158),39.87％ (63/158),17.72％ (28/158),18.99％ (30/158),29.11％ (46/158),36.08％ (57/158),82.91％ (131/158),the differences were statistically significant (x2 =8.725,27.167,12.742,95.064,5.825,14.056,18.478,7.314,P ＜ 0.05).However,there were no significant differences in terms of diabetes history,drinking,high density lipoprotein-cholesterol level and low density lipoprotein-cholesterol between two groups.Conclusion Hemorrhagic stroke is closely related to many factors.Sex,age ＞ 70 years,smoking,obesity,history of hypertension,high cholesterin (TC ≥ 5.7 mmol/L) are independent risk factors of patients with hemorrhagic stroke in elderly.Through the control target population's blood pressure and blood lipids,rational diet,appropriate exercise,quit smoking and alcohol,adjust the good point of view,we can prevent the occurrence old hemorrhagic stroke.

OBJECTIVE: To study the preventive and therapeutic effect of Weitong injection(WTI) on the postoperative intestinal adhesion of rats.METHODS: Forty SD rats were randomly divided into five groups: blank control group,model control group,Dexamethasone group and high-dose WTI group and low-dose WTI group.Postoperative intestinal adhesion model was established in all the rats except those in the blank control group.On the operative day,the blank control group and the model control group received Normal saline(1 mL?kg-1);the Dexamethasone group received Dexamethasone(5 mg?kg-1),and WTI group received WTI(4 mg?kg-1 and 2 mg?kg-1,respectively) all via vena caudalis for 7 consecutive days.On day 8,laparotomy was performed on the rats for the evaluation of the degree of intestinal adhesion and the tissue of cecum was collected for the determination of the content of hydroxyproline(Hyp) and the pathological section test.RESULTS: The degree of postoperative intestinal adhesion of rats was attenuated by WTI(either high dose or low dose) or Dexamethasone.Furthermore,WTI significantly reduced the Hyp concentration in cecum tissue of rats with intestinal adhesion(P

Objective To recognize normal sinus rhythm (NSR), ventricular tachycardia (VT) and ventricular fibrillation (VF) from each other accurately and promptly. Methods A nonlinear descriptor based on multi-scale analysis, Hurst index, as a feature to quantify the nonlinear dynamics behavior of the ECG signal, was quoted in this paper. Results The nonlinear technique, Hurst index was examined and evaluated with ECG signals extracted from MIT-BIH Arrhythmia Database, MIT-BIH Malignant Ventricular Ectopy Database, and CU Ventricular Tachyarrhythmia Database under a specific moving-window length. The experiment showed good performance of this nonlinear descriptor. When the window length was 5 s long, the recognition accuracy for each of NSR, VT and VF was 100%. Besides, the computing speed was much faster than the speed obtained with a traditional non-linear technique, the complexity measure algorithm. Conclusion The Hurst index has a strong potential for life-threatening ventricular arrhythmia recognition in clinical applications.

OBJECTIVE:To reduce dispensing errors in Pharmacy intravenous admixture service(PIVAS),improve compound-ing quality of transfusion and guarantee the safety and rationality of clinic transfusion. METHODS:The case tracking method was applied to analyze each link of the work in PIVAS to find the reasons of configuration errors and control risk;and then the system tracking method was applied to analyze the hidden safety risk and the crack of quality from the inside of the system and work flow. Countermeasures and supporting continuous improvement were established to evaluate the effect of management before and after 6 months. RESULTS:Tracer methodology(TM)was adopted to find out the weakness in the key link and work flow of the cause of the configuration errors,the relative work pattern and work environment was improved,the relative system was formulated and completed,strength of rewards and punishment was increased. Through the implementation of the countermeasures,the number of dispensing errors was reduced from 81 to 38,and the error rate was reduced from 0.035% to 0.011%(P<0.01). CONCLU-SIONS:TM can be adopted in the key link and work flow of the cause of the configuration errors,aim at formulate and strictly carry out relative countermeasures to reduce errors in PIVAS,and promote the safety of drug use.

In recent years,many breast cancer therapeutic vaccines have been entered several clinical trials,which bring a new promising treatment for breast cancer.These trials reveal the advantages and characteristics of tumor-associated antigens,and put forward the questions waiting to be solved.

Psychotherapy is a sort of arts based on science following the general principles of social science and natural science.Meanwhile,the content of psychotherapy,the process of the practice,and the relationship be-tween the help-seekers and the helpers reflect substantial humanistic connotation and are bound up with cultural and subcultural transmission and reality context.This paper is a commentary on the article written by an Indonesian fel-low T.Citraningtyas discussing the mother's role in the matriarchal society and its modern meanings.We discussed that the phenomenon of being cultural extinctionalso presents in China.Although the main stream in Chinese cul-ture is still patriarchic familism,the remainder of matriarchal society still exists in the basic emotional models of parent-child relationship.The deprivation and frustration related with filial piety and kinship may cause the conse-quence of cultural extinctionin the individual level.Referring the theory of Wen-Shing Tseng on the mechanisms of the cultural influence on psychopathology,from the perspective of understanding psychology,we emphasized the importance of cultural empathy and recommended the systemic clinical thinking way of empathic considering and contextualizing.Last but not least,we discussed the second case of the overseas migrant workers and their left-at-home childrenin this article within Chinese context.Moreover,besides the 61 million left-at-home children in rural areas,there are a large amount of substitute-raised children by their grandparents who might be also in the risk of being impaired physically and psychologically.This problematic phenomenon may relate to the living stress and the cultural encouragement as well.By providing a critique discussion with the related theories of correlation of the in-secure attachment with psychological disorders in childhood and adulthood,this commentary encouraged humble learning from our Indonesian fellows and appealed for greater appreciation of separate mothers and their children a-mong Chinese clinicians.

Objective: To study the effective treatment methods of arteriovenous malformation(AVM) in jaw bone through retrospective review. Methods:33 patients with jaw AVM were analyzed by history, treatment methods and outcome. Results: Among the 33 patients 6 were treated by embolization only, 12 by curretting, 10 by resection of the bone lesions. The cure rate in the three groups was 2/6,11/12 and 10/10 respectively. Conclusions: Embolization combined with curretting may be the effective methods to treat facial bone AVM without resection of bone.
