ABSTRACT
Objective To explore the correlation of fatigue with health-promoting lifestyle in the udnergraduate students, so as to provide scientific evidence for the intervention. Methods A cross-section trial was carried out in the undergraduate students from a medical university in Guangzhou. By a self-designed questionnaire, the incidence of fatigue in the undergraduate students was figured out after data processing and statistical analysis. Results A total of 6 100 questionnaires were released, and 5 843 were responded, with a respondent rate being 95.79%. The number of effective questionnaires arrived 5 676. The results showed that the prevalence of fatigue among undergraduate students was 49.6%. The female had a higher risk than the male ( 51.6% vs 45.8%, P0.05). The students with poor level of health-promoting lifestyle had a higher risk of suffering from fatigue (OR=6.647, 95%CI: 4.913-8.993). Conclusion Fatigue is prevalent among the undergraduate students. The incidence of fatigue can be reduced by increasing the level of self-actualization, physical exercise and pressure management.
ABSTRACT
Objective To investigate the changes of traditional Chinese medical constitution types with menstrual cycle of sub-health state women, thus to explore the affectability of diseases during menstrual cycle. Methods Sub-health State Questionnaire and Menstruation State Questionnaire established in our previous study were used for the epidemiological survey of 330 women outpatients aged 20-45 years admitted by the disease-preventive department of Tianhe District Hospital of Traditional Chinese Medicine. Results In 330 cases, the cases of sub-health state accounted for 64.5%, in which 21.5%had pure sub-health state without any chronic diseases, and 43.0% had sub-health state together with some diseases. The diseases of hyperplasia of mammary glands, vaginitis, cervical spondylosis, hyperlipemia, chronic appendagitis, and uterus myoma had higher morbidity rate in order. At premenstrual phase, constitution types of Qi stagnation, damp heat, and blood stasis had the higher incidences; at menstruation phase, Qi stagnation, blood stasis, and damp heat had the higher incidences; at postmenstrual phase, yang deficiency, Qi deficiency, and damp heat had the higher incidences. Most of the sub-health state women had the complex constitution types, accounting for 93%. Conclusion Traditional Chinese medical constitution types are correlated with menstral cycle of sub-health state women, and show some effects on the affectability and progress of diseases. The investigation results of dynamic changes and the distribution of traditional Chinese medical constitution types during menstrual cycle will supply some evidence for the prevention and treatment of irregular menstruation and sub-health state of the women with Chinese medine.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship between the occurrence of sub-health and health promotion lifestyle in Guangdong province to provide epidemiological evidences for prevention of sub-health.</p><p><b>METHODS</b>A 1:1 nested case-control study was carried out involving 133 cases from the cohort study paired with 133 control case matched for gender and age.</p><p><b>RESULTS</b>The univariate conditional logistic regression model showed no significant association of marital status, education level, or body mass index with the occurrence of sub-health, but a significant correlation was found between lifestyle and sub-health with an odd ratio of 5.90 (95% CI: 3.12-11.16, P=0.000). Analysis of the multivariate conditional logistic regression model on the 6 subscales of health promotion lifestyle showed that stress management was significantly correlated with the occurrence of sub-health with an odd ratio of 4.00 (95% CI: 1.54-10.40, P=0.004).</p><p><b>CONCLUSION</b>A unhealthy lifestyle, especially in terms of stress management, is the major risk factor contributing to the occurrence of sub-health.</p>

Objective To evaluate the biological safety of 125I-filled carbon nanotubes covered with metallic esophageal stent with regard to the normal esophagus before clinical application.Methods 125I-filled carbon nanotubes covered with metallic esophageal stent was prepared.Eighteen of New Zealand rabbits were randomly divided into three groups with 6 rabbits in each group.Three groups of stents,non-radioactive,low radio-activity ( 3.7 - 5.6 MBq),and high activity ( 11.1 - 13.0 MBq ) were placed in the midpiece of esophagus of rabbits.Esophagus opacification and three-diamensions DSA were performed at 0.5 h,7,14 and 30 d after insertion of the stents,respectively.The rabbits were killed at 30d after insertion of the stents,and histologic examinations of the esophageal walls were performed.Results In non-radioactive and low activity groups,1 of 6 rabbits died of wound infection at 1 and 3 d after surgery due to pulmonary infection,respectively.All specimens were obtained from 16 rabbits.Microscopically,in all rabbits of low activity and high activity groups,there were membrana mucosa necrotic and swell and breakage of the muscle fiber in esophageal submucosa and muscularis,submucosal inflammation,which were more severe in high activity group.In low activity group,one esophagus ectal membrane was involved,however,esophageal perforation did not develop.In high activity group,3 of 6rabbits esophageal perforation had developed,in which one esophagus mediastinum fistula developed,without inflammation.In non-radioactive group,it was almost normal in mucosa layer,a small amount of inflammatory cells were found in submucosal layer,and part of muscle fibers was fractured and no pathological changes of necrosis was found.Conclusions Radioactive 125I carbon nanotubes covered metallic stent with low activity(3.7 -5.6 MBq) can be used as intraluminal palliative brachytherapy,which is safe and effective.
ABSTRACT
Objective To evaluate the rationale and indcations for exploring common bile duct through cystic duct without placing"T"tube after choledochotomy.Methods Exploring 30 patients'common bile duct through cystic duct without placing"T"tube after choledochotomy.The results was compared with that of traditional procedure.Results Average postoperative hospital stay was 8 days.while 16 days in patients with a"T"tube drainage.Complications often seen in"T"tube drainage were avoided.Conclusion When properly,exploring of common bile duct through cystic duet without"T"tube was safe.
