Conclusion Lateral collateral ligament reconstruction surgery combined with arthroscopy in treatment of chronic lat-eral ankle instability has better clinical efficacy,the recurrence rate is low,and has less complications.

Objective To explore the relationship between Confucian coping and life meaning searching and assertion. Methods 378 undergraduates were assessed by the subscale " Meaning Searching and Assertion" in the life attitude profile scale (LAP) and the Confucian coping questionnaire. Results The role of adversity to individual growing,optimism in the adversity and the responsibility as human being were significantly related to life meaning searching and assertion,as well as each factor( r = 0. 412, r = 0. 630, r = 0. 374, P＜0. 01). The viewpoints to "fate" was significantly related to life purpose and life control( r= -0. 113, r= -0. 141, P＜0. 05). Regression analysis showed the role of adversity to individual growing,optimism in the adversity and the responsibility as human being are main predictor of life meaning searching and assertion. Conclusion Confucian coping can predict the individual level of life meaning searching and assertion.

Objective To explore the classification of abnormal electroencephalogram of children with cerebral palsy (CP) and the relationship between the electroencephalogram and the CP type.Methods152 CP children were examined with the electroencephalogram. The data of electroencephalogram were analyzed.ResultsThe abnormal electroencephalogram rate of 152 CP children was 40.13%. The abnormal electroencephalogram rate of the children with athetoid was lower (8.33%). The abnormal electroencephalogram rate of the children with spastity hemiplegia was higher (71.43%).ConclusionThe abnormal electroencephalogram rate of the CP children is related with the location of cerebral injury.

ObjectiveTo examine the relationship between belief in a just world of college students and prosocial tendencies.Methods400 college students were examined by using the belief in a just of Chinese versions ( BJW ) and the prosocial tendencies scales.Results①There was a marginally significant difference on college student's general belief in a just world and personal belief in a just world among different grades ( F=3.90,F=3.05,P ＜ 0.05 ).②The personal belief in a just world and general belief in a just world was significantly posilively correlated with the prosocial tendencies of college students ( r =0.25,r =0.24,P ＜ 0.01 ).③Significant differences existed between the high-scoriug,the middle group and the low-scoring BJW group in prosocial tendencies and its sub-dimensions ( F =3.36 ～ 12.87,P ＜ 0.05,P ＜ 0.01 ),expect the openness dimension of prosocial tendencies( F =1.71,P ＞ 0.05 ).The scores of those three groups on prosocial tendencies ( (3.74 ± 0.43 ),( 3.57 ± 0.42),( 3.44 ± 0.43 ) ) and its sub-dimensions shows a decreasing trend from high to low.④Layer multivariate linear regression analysis showed that general belief in a just world were significant predictors of the prosocial tendencies( β =0.18,P＜ 0.01 ).ConclusionsThe intensity of belief in a just world has a certain impact on the prosocial tendencies of college students.

Objective:To study the tissue speciality of endothelium-dependent vascular relaxation mediated by endothelial protein activated by acetylcholine (EPA)and its relationship with atherosclerosis.Methods:The tension of the isolated artery preparations was recorded using isometric-tension method and the isolated endothelium-intact vessels derived from normal and hyperlipidemic animal artery.Results:The EPA-mediated endothelium-dependent vascular relaxation was exhibited in rabbit aorta, renal, femoral, carotid, pulmonary arteries and cat aorta, renal, femoral, mesentery, coronary arteries but with different EC50. The sensitivity of EPA to ACh in descending order: pulmonary>renal>aorta>femoral>carotid arteries in rabbits. In cats,coronary>aorta>femoral>mesentary>renal. The endothelium-dependent vascular relaxation mediated by EPA in aorta, carotid and pulmonary arteries decreased significantly in hyperlipidemia rabbits.Conclusions:EPA effect existed wildly in testing artery and was of different tissue sensitivity. The decrease in EPA potency was closely related to occurence of atheroclerosis.

OBJECTIVE: To explore the clinical application of gastric pharyngeal anastomosis assisted by laparoscope. METHOD: Apply laparoscope in the gastric pharyngeal anastomosis for 4 cases of advanced hypopharyngeal carcinoma and cervical esophageal carcinoma patients. RESULT: Gastric pharyngeal anastomosis assisted by laparoscope were successfully completed in all 4 patients, all patients avoided thoracotomy or laparotomy, one patient occurred pharyngeal fistula, and died six months later. One patient had cervical lymph node metastasis a year and a half later, without treatment again because of economicissue. The remaining two patients were still alive, one patient had survived 3 years and a half after operation, the other had survived 2 years and a half after operation. CONCLUSION Gastric pharyngeal anastomosis assisted by laparoscope is feasible. It can reduce the operation wound, improve the safety of operation and patients' life quality.
