BACKGROUND: At present, it is affirmed that coping style is the important mediator between stress and health both on mental and body. The coping theory is descripted as three orientations: trait view, contextual view and interaction person-environment view. The conception and classification of the coping styles still remains to be explored. OBJECTIVE: To probe into the dimensions of coping styles, the characteristics of different coping styles and the correlation between coping styles and psychological adaptation among college students.DESTGN: Questionnaire investigation.SETTING: School of Psychology, Beijing Normal University.PARTICIPANTS: Altogether 343 college students were randomly chosen from Tianjin University, Tianjin University of Commerce, Tianjin Normal University and Tianjin University of Finance and Economics. The college students, including 161 males and 182 females, were aged (19±2) years, ranging from 19 to 22 years. According to body health examniation records of them, all the college students had no serious chronic or acute illness. Written informed consents were obtained from all the college students.METHODS: The college students were measured collectively in their own classroom respectively from September to December in 1999. There were totally 16 class units. Altogether 422 copies of questionnaire files were sent out. Each copy includes Coping Styles Scales, Adolescent Psychological Adaptation Scales, and SCL-90.The questionnaires were collected once the college students completed. Copying styles were assessed with Coping Style Scale revised by Liang Baoyong, which includes 20 items. Each item gives one kind of coping strategies in daily life. For example, "To tell myself,my trouble is nothing matter When comparing with others, it is no worthy to be annoyant". The college students should be asked to answer on the 5-point Likert scale. These 20 items covered majority of coping styles which were used by adolescents. Two indexes were used as the results of psychological adaptation: one is Adolescent Psychological Adaptation Scale developed by Chen Huichang, including 20 items. Scores were collected on the 5-point Likert scale in which high scores mean better adaptation. Another result variable is the amount of SCL-90. High scores mean more symptoms with mental or physical state which stands for lower adaptation level. All the assessment data were input into Foxbase data-base, then were analyzed using factor analysis and cluster analysis in order to attain different kinds of college students coping styles. Correlation analysis was used to examine the correlation between coping style and adaptation. MAIN OUTCOME MEASURES: Coping styles of college students and correlation between different coping styles and adaptation results.RESULTS: A total of 422 copies of questionnaires were sent out, and 362 copies were drawn back, 19 copies were invalid questionnaires due to either there were missing answers or the answer had reflective tendency. At last, 343 sets of data entered the analysis procedure. ① According to factor analysis results, the main coping styles used by college students were F1 (seeking support), F2(positive thinking), F3(cognitive adjustment), F4(passive blame oneself), F5(facing reality), F6(avoidance), F7(emotional catharsis).There were three main coping styles from cluster analysis, that was, A (positive confrontation), B (passive avoidance) and C(passive catharsis).② Those who were more adaptive used A coping style more frequently, and those who had lower adaptation level used B or C coping style more frequently. But few students used C coping style. A coping style was significantly negatively correlated with mental or physical symptoms (r= -0.258,P＜ 0.01 ),but significantly positively correlated with adaptation level (r =0.467, P ＜ 0.01);But both B and C coping styles were significantly positively correlated with mental or physical symptoms (r=0.338, 0.364, P ＜ 0.01 ), B coping style was significantly negatively correlated with psychological adaptation(r =-0.140, P ＜ 0.05). It seemed that C coping style had no correlation with long-term adaptation. A and C coping styles were two dependent styles respectively. In addition, different levels of stress were significantly correlated with three styles. Few A coping styles were used under high level of stress, but more B and C coping styles did.CONCLUSION: Coping style is complex. Use of different copying styles is significantly correlated with psychological adaptation levels. But the direction of correlation is effected by the factors, such as individuals, index of results and degree of stress.

Objective To investigate the relationship between myeloperoxidase(MPO) and ankle brachial index(ABI) in patients with htypehypertension.Methods A total of 133 patients were enrolled in this study,and divided in to htypehypertention group(n=72),non-htypehypertension group(n=30) and normotension group(n=31).Their Hcy,ABI and MPO levels were measured and compared.Results The ABI in htypehypertention group and non-htypehypertension was significantly lower than that in normotension group (P<0.05),ABI in non-htypehypertension group was lower than that of htypehypertonsion group(P<0.05).MPO and CRP in the htypehypertension group was significant higher that those of normotension group(P<0.05).The ABI was negatively related with the serum MPO and CRP levels in htypehypertention group (r=-0.712,-0.722,P<0.05).Conclusion ABI is closely related with MPO,and play an important role in diagnosis of artery function impairment and high risk of htypehypertension patients.

BACKGROUND: Colonic manometry is a widely used method to assess digestive tract function and is of crucial importanoe in evaluating colonic activity disorder.OBJECTIVE: To analyze the kinematic and kinetic eatures f intestinal tract pressure signal of healthy volunteers and patients with abnormal colonic pressure.DESIGN: Contrast observation experiment.SETTING: People's Hospital of Shanghai Pudong New Area.PARTICIPANTS: Two groups of participants were organized. The patient group consisted of six patients ith abnormal colonic function. They received treatment in the People's Hospital, Shanghai Pudong New Area etween January 2000 and August 2001. These patients were not allowed to take any medicine or foods that ould affect intestinal motility within two weeks prior to the study. The control group consisted of nother 2 healthy volunteers who received health examination homeochronously. Informed consents were btained from all the participants. Gastrointestinal tract functionamonitor manufactured by CTD2SYNETICS ompany (Sweden) was employed.METHODS: Participants were asked to lie down on their left sides for 30 inutes quietly before the manometer entered the ileum with the help of an enteroscope. A water bag was ttached to the end of manometer and was filled with water to increase the end weight. The enteroscope was sed to inhale the intra-intestinal gas while it was pulled out. Afterwards, the water bag was emptied. Easurement began after the participant was asked to lie down for another 30 minutes to deplete the bnormal contraction of intestinal tract caused by enteroscope. Every inspection took about 20 minutes. Ubsequently, the water bag was filled with 50 mL water and the gas bag with 50 mL air to simulate the timulation of faeces. The simulation inspection also lasted about 20 minutes. During the measurement rocess, the precise position was determined by a B-type ultrasonic inspection system. The manometer was hen pulled out 20 cm and the same inspection process was repeated. Fractal dimension of intestinal tract ressure was calculated with the method from Higuchi to distinguish normal and abnormal colonic pressure ignal.MAIN OUTCOME MEASURES: Fractal dimension analysis of intestinal tract pressure signals.RESULTS: xtensive analysis was conducted for pressure signals of two healthy volunteers and six patients. The racta dimensions of intestinal tract pressure data from normal subjects basically kept around a certain alue, while those from patients varied greatly. There was something wrong with colonic contractions of ntestinal tract of the patients, as the associated fractal dimensions, were around "1".CONCLUSION: ractal imension of intestinal tract pressure signals is calculated, and the resultant fractal dimension can be sed as an index to distinguish normal and abnormal colonic pressure signals.
