BACKGROUND: It has important praxis significance to penetrate into the mental health status and satisfaction with life of home-going peasant workers in order to improve their mental health level and quality of life.OBJECTIVE: To analyze the correlation the mental health and satisfaction with life of home-going peasant-workers, so as to provide a sound basis for effectively intervening their mental crisis and improving their satisfaction with life.DESIGN:A sampling survey.SETTING: Department of Educational Science of Hengyang Normal University.PARTICIPANTS: This investigation was conducted in 15 provinces of China in February 2005. Totally 300 home-going peasant-workers were surveyed during the Spring Festival.METHODS: The peasant-workers were tested individually with symptom checklist 90 (SCL-90) and the satisfaction with life scale (SWLS); they were given uniform directions and answered each question individually according to their own conditions in the latest week. All the answer papers were handed in on the spot. The data of SCL-90 and SWLS were input into the computer for statistical analysis. The SCL-90 questionnaire in which more than 5 items were left unanswered or the total score was below 95points and the SWLS questionnaire in which more than 4 items selected the answer of "neither agree nor disagree" were considered to be invalid and therefore rejected for analysis. All the datawere input into the computer and statistically analyzed with SPSS 11.0 software; the correlation analysis of the factors of SCL-90 and SWLS was surveyed with coefficient of product-moment correlation, the t test was applied for the significance of correlation coefficient.MAIN OUTCOME MEASURES: The correlation between mental health and satisfaction with life of home-goingpeasant workers was anlayzed.RESULTS: Totally 300 questionnaires were sent out, 275 were handed in,and the collective rate was 91.67%. Finally 245 effective participants entered the analysis of results, including 118 males and 127 females, aged 16-52 years old, with an average of 26.09 years old. The total score of SWLS was negatively correlated with the total score of SCL-90 and the scores of obsession-compulsion, interpersonal sensitivity, depression, anxiety and paranoid ideation (r=0.167, -0.168, -0.208, -0.214, -0.139, -0.126,-0.200, P＜0.05-0.001). The score of "In most ways my life is close to my ideal" had no obvious correlation with the total score and factor scores of SCL-90. There were significant correlations between the factor score of "The conditions of my life are excellent" and the two factor scores of interpersonal sensitivity and depression of SCL-90 (r=-0.136,-0.143, P＜0.05).The factor score of" I am satisfied with my life" had significant correlations with the total score of SCL-90, the number of positive items and the factor scores of obsession-compulsion, interpersonal sensitivity, depression,anxiety and paranoid ideation (r=-0.168, -0.148, -0.184,-0.214, -0.181,-0.162, -0.168, P＜0.05-0.001). The factor score of "So far I have gotten the important things I want in life" had significant negative correlations with the factor scores of interpersonal sensitivity, depression and paranoid ideation (r=-0.167, -0.128, -0.184, P＜0.05-0.001). The factor score of "If I could live my life over, I would change almost nothing" was in significant negative correlations with the total score of SCL-90, the number of positive items and all the factor scores of SCL-90 (r=-0.221, -0.175, -0.143,-0.179, -0.225, -0.273, -0.174, -0.176, -0.157, -0.246, -0.165, P＜0.05-0.001).CONCLUSION: There is a positive correlation between the mental health level and satisfaction with life in home-going peasant-workers.

BACKGROUND: As a typical small cluster of social vulnerable groups in China, peasant-workers have aroused extensive attention because of their social situation. Therefore, it has important praxis significance for establishing harmonious society to penetrate into the status of their satisfaction with life and improve their quality of life.OBJECTIVE: To investigate the status of satisfaction with life of homegoing peasant-workers so as to provide a sound basis for improving their quality of life.DESIGN: A simple random sampling survey.SETTING:Department of Educational Science of Hengyang Normal University.PARTICIPANTS: This investigation was conducted in 15 provinces of China in February 2005. Totally 300 home-going peasant-workers weresurveyed during the Spring Festival.METHODS: The peasant-workers were tested individually with the Satisfaction with Life Scale (SWLS). It was made up of 5 items:The first item was "In most ways my life is close to my ideal ", the second was "The conditions of my life are excellent", the third was "I am satisfied with my life", the fourth was "So far I have gotten the important things I want in life", the fifth was "If I could live my life over, I would change almost nothing". Using the 1-7 scale below: 1-Strongly disagree, 2-Disagree, 3-Slightly disagree, 4-Neither agree nor disagree, 5-Slightly agree, 6-Agree, 7-Strongly agree.The test-retest reliability of this scale was higher than 0.80, the content-related validity was 0.60, and the crieterionrelated validity was higher than 0.50. They were given uniform directions and answered each question individually according to their own conditions in the latest week. All the answer papers were handed in on the spot. The data of SWLS were input into the computer for statistical analysis. The questionnaire in which more than 4 items were selected the answer of "neither agree nor disagree" were considered to be invalid and therefore rejected for analysis. All the valid data were input into the computer and statistically analysed with SPSS 11.0 software; differences among groups were compared with t test or analysis of variance.MAIN OUTCOME MESURES: The scores of SWLS answered by the peasant-workers.RESULTS: Totally 300 questionnaires were distriluted and 275 of them were collected, with a recovery rate of 91.67%, of which 245 were valid for result analysis, including 118 males and 127 females aged from 16 to 52 years old with the mean age of 26.09 years. They came from 15 provinces of China and from 16 kinds of vocation. Their monthly-earning was from 200 yuan to 8 000yuan. The investigated results of SWLS showed that: ①29.8% of the tested home-going peasant-workers were inclined to be satisfied with their life, and 41.6% of them were inclined to be unsatisfied. ②There was obviously sexual difference in the item of "I am satisfied with my life"among the tested homegoing peasant-workers.[(4.50±1.70,3.95±1.53) (t=2.65,P ＜ 0.001 )]. ③Earning markedly affected their feeling of "The conditions of my life are excellent" and "So far I have gotten the important things I want in life" [(3.79±1.85, 3.98±1.64,4.07±1.44,4.84±1.14) (F=3.068,P ＜ 0.05); (4.64±2.03,3.72±1.68,4.07±1.67,4.19±1.28) (F=2.813,P ＜ 0.05)]. ④there was no significant difference of satisfaction with life of the tested home-going peasant-workers in educational level and term on duty. CONCLUSION: Majority of the home-going peasant-workers were unsatisfied with their living. Sex and earning were the important factors that affected their satisfaction with life, educational level and term on duty had weakly correlated with it.

BACKGROUND: As a typical puny cluster in China, peasant-workers have aroused extensive attention because of their social situation. Therefore, it has important praxis significance for establishing harmonious society to penetrate into their mental health status and improve their mental health level.OBJECTIVE: To investigate the mental health status of home-going peasant-workers, so as to provide a reliable basis for the effective intervention of their mental crisis.DESING: A cross-sectional survey.SETTING: Department of Educational Science of Hengyang Normal University.PARTICIPANTS: The investigation was conducted in 15 provinces of China in February 2005. By means of cross-sectional survey, 300 randomly selected home-going peasant-workers were surveyed during the Spring Festival.METHODS: The peasant-workers were tested individually with symptom checklist-90 (SCL-90); they were given uniform directions and answered each question individually according to their own conditions in the latest week. All the answer papers were handed in on the spot. The data of SCL90 were input with Optical Mark Reader 2000 (OMR2000) into the computer for statistical analysis. The questionnaire in which more than 5 items were left unanswered or the total score was below 95 points was considered to be invalid and therefore rejected for analysis. All the data were input into the computer and statistically analyzed with SPSS 11.0 software; the intergroup differences of the measurement data were compared with the t test or analysis of variance.MAIN OUTCOME MEASURES: ① general mental health status of the home-going peasant-workers; ② mental health status compared among the home-going peasant-workers of different gender, educational level, term on duty and earning.RESULTS: Totally 300 questionnaires were sent out, 275 were handed in,and the collective rate was 91.67%. Finally 245 effective participants entered the analysis of results, including 118 males and 127 females, aged 16-52 years old, with an average of 26.09 years old. The investigated results of SCL-90 showed that ① The total score and number of positive items of SCL-90 in the tested peasant-workers were significantly higher than those of Chinese adult norm (173.13±44.35, 129.96±38.70, t=15.237,P ＜ 0.001; 52.96±20.27, 24.92±18.14, t=21.654, P ＜ 0.001). ②The scores of somatization, obsession-compulsion, interpersonal sensitivity, depression,anxiety, hostility, phobia anxiety, paranoid ideation and psychoticism of the tested peasant-workers were significantly higher than those of the Chinese adult norm (1.73±0.55, 1.37±0.48, t=10.260, P ＜ 0.001; (2.12±0.56, 1.62 ±0.58, t=14.092, P ＜ 0.001; 2.10±0.59, 1.65±0.61, t=12.076, P ＜ 0.001;1.99±0.59, 1.50±0.59, t=13.072, P ＜ 0.001; 1.88±0.53, 1.39±0.43; t=14.260,P ＜ 0.001; (1.98±0.69, 1.46±0.55, t=11.951, P ＜ 0.001; 1.74±0.58,1.23±0.41, t=13.692, P ＜ 0.001; 2.00±0.61, 1.43±0.57, t=14.647, P ＜ 0.001;1.81±0.57, 1.29±0.42, t=14.472, P ＜ 0.001). ③ The mental health status had no obvious differences among the peasant-workers of different gender,educational level, earning and term on duty.CONCLUSION: The mental health status of the home-going peasant workers is significantly lower than that of Chinese norm, gender, educational level, earning and term on duty have great influence on the mental health of the home-going peasant-workers.

Objective To explore the relationship between health-risk behaviors and personality disorders in undergraduates.Methods A total of 290 undergraduates were surveyed with the Adolescent Health Related Risky Behavior Inventory (AHRBI) and the Personality Diagnostic Questionnaire-4+ (PDQ-4+),and the whole data was analyzed by t-test and Pearson's correlation analysis.Results (1) The factors scores of AHRBI were significantly positively related with the factor scores of PDQ-4+ in the undergraduates (r=0.12-0.48,P＜0.05).(2) The positive groups of Paranoid,schizoid,schizotypal,histrionic,narcissistic,borderline,antisocial and depressive personality disorders performed higher scores of AHRBI (1.57±0.44,1.63±0.52,1.54±0.40,1.78±0.73,1.54 ±0.41,1.62± 0.41,1.61 ± 0.41,1.54 ± 0.37 respectively) than those of the corresponding negative groups (1.37 ±0.24,1.38±0.26,1.37±0.26,1.38±0.25,1.37±0.25,1.35±0.22,1.35±0.21,1.38±0.27 respectively) (P＜0.05).Conclusion Personality disorders are closely related with health-risk behaviors of undergraduates,and different health-risk behavior possesses different vulnerability of personality disorder.

BACKGROUND: College students of normal universities, the major supply of teachers, have influences on their latter career of teacher man.OBJECTIVE: To investigate the mental health of freshmen of local normal university in 2005, so as to provide the basis for mental health education and mental counselling.DESIGN: Cluster sampling and cross-sectional investigation.SETTING: Department of Education Science, Hengyang Normal University.PARTICIPANTS: This experiment was carried out in Hengyang Normal University in October 2005. Totally 3 089 freshmen of Hengyang Normal University in 2005 were selected as the participants, including 1 211 male and 1878 female with the mean age of 18.72 years.METHODS: The freshmen were tested by Symptom Check List- 90 (SCL-90)in groups after their enrolment a month later. Before answering the questions, they were given uniform directions and answered every question individually according to their own conditions in the latest week. All the answer papers were handed in on the spot. The data of SCL-90 were inputwith Optical Mark Reader 2000 (OMR2000) into Psychometrics Toolbox STD V3.0 of Psychology Exploring System for calculation of total score and the score of each factor. The unanswered items in SCL-90 were labelled as "never", if more than 5 items were unanswered, the questionnaire was considered to be invalid and therefore rejected for analysis. The total score below 95 points in a questionnaire was considered to suggest low reliability of answers and the questionnaire was also rejected. All the data was input into computer and statistically analysed with SPSS 11.0 software. Differences among groups were compared by using t test.MAIN OUTCOME MEASURES: The scores of SCL-90.RESULTS: Totally 3 089 questionnaires were distributed and 2 994 of them were collected, with the effective rate of 96.92%, including 1 180male, 1 814 female, 2 847 freshmen of liberal arts and 1 147 freshmen of science. All the nine SCL-90 factor scores of the tested freshmen were significantly higher than those of Chinese youth's norm (P＜0.01). The female freshmen had significantly higher scores than the male freshmen in the factors of somatization, obsessive-compulsive, interpersonal sensitivity,depression, anxiety and phobia anxiety(P＜0.05-0.01 ), and contra in the factor of hostility(P＜0.01). There was no significant sex difference in the factor of paranoid ideation and psychoticism. The freshmen of liberal arts had significantly lower scores than the freshmen of science in the factors of obsessive-compulsive, hostility and psychoticism(P＜0.05-0.01 ), and contra in the factor of phobia anxiety(P＜0.05), there was no significant difference in the other factors between the two groups.CONCLUSION: The mental health level of freshmen of local normal university is lower than the average level of Chinese youth. The mental health status of the female freshmen is lower than that of the male freshmen. In obsessive-compulsive, hostility and psychoticism items,the freshmen of liberal arts and science are better than the freshmen of science, but in phobic anxiety items, it is contrary.

Objective To evaluate the feasibility of application of video-laparoscopy to the treatment of acute severe inflammatory pelvic pain in women. Methods Forty-two women patients with severe acute inflammatory pelvic pain were divided randomly into two groups with 21 patients in each group. Conservative therapies were carried out in Group A while laparoscopic operations in Group B. Results Eighteen cases (85.7%) in Group A returned to health, and in the remaining 3 (14.3%), conservative measures failed and thus exploratory operations were performed. Meanwhile all the patients in Group B were treated successfully, with the operative time (42.5?20.6) min, the average blood loss 20ml and the mean hospital stay 7 days. Body temperatures returned to normal on the day of operation and no complications occurred. Conclusions Laparoscopy may be feasibly applied to the treatment of women with severe acute inflammatory pelvic pain, producing results superior to conservative therapies.

Objective To study the bacteriostatic effect of the volatile oil from Artemisia argyi. Methods Minimal inhibitory concentration (MIC) was measured with double-fold didution method. Protective effect of the volatile oil from Artemisia argyi were determined by experimental treatment of infected mice in vivo.

Conclusion The volatile oil from Artemisia argyi has better inhibiting effect on Staply lococcus aureus, Escherichiacoli and Pseudomona than Erythromycin. It has better protective effect for infected mice.

Objective To evaluate the efficacy of inferior vena cava filter placement guided by digital subtraction angiography(DSA) for the prevention of pulmonary embolism(PE) after deep vein thrombosis(DVT) of the lower extremities.Methods Under the guidance of DSA,inferior vena cava filter placement was performed in 14 cases of deep vein thrombosis of the lower extremities from October 2003 to December 2004.Of the 14 cases,12 cases were given a simultaneous thrombectomy and 2 cases were treated conservatively.Results Filters were successfully placed in all the cases.The operation time was 85~115 min(mean,95 min).No complications were found during a follow-up of 1~14 months(mean,6 months).No recurrence of pulmonary embolism was seen included 5 patients who had survived previous pulmonary embolism attacks before the placement.Conclusions Inferior vena cava filter placement is a simple,safe,and effective method in the prevention of pulmonary embolism after deep vein thrombosis of the lower extremities.

Objective:Defensins from human neutrophils exhibit a broad antimicrobial activity.The transfection of the gene fused by human neutrophil peptide 1(HNP1) with the J chain into other cells may induce the in vitro expression of HNP1 to play antimicrobial roles.The authors analyzed the influencing factors on the expressed proteins of HNP1 and the J chain gene in COS-7 cells.Methods: Western blot was used to analyze the technical factors influencing the HNP1 protein expression.Results: Recombinant J-HNP1 was expressed in the cells successfully.Conclusion: The expression of J-HNP1 can be detected inside and outside the cells by Western blot.

Objective To probe the effects of the size and location of cranial defect on the neurological symptoms of patients with skull bone defect.Methods The patients were classified into the following groups according to the influence to symptoms by changes in body position and changes of symptoms before and after craniectomy: True syndrome of the trephined(ST,Ⅰ), partial ST patients(Ⅱ), other patients or symptom-free patients (Ⅲ).Results The group I consisted of 33 cases, their defects were located in the parieto-occipital region in 23 cases, frontoparietal in 10 cases. All these patients had flaccid skin flaps that became concave while in the upright position. The group Ⅱ was composed of seven cases, their defects were located in frontoparietal and parieto-occipital region in three respectively. All these patients had flaccied skinflap in defects pars.Group Ⅲ included twelve patients, flat and rigid skin flaps were usually demonstrated , predominantly in the tempora and parietal regions.Conclusions The size and location of the cranial could play an important role in the development of the neurological symptoms.
