ABSTRACT
Objective:To investigate the mental health status of postgraduates in a medical university in southwest China and analyze its influencing factors.Methods:A total of 622 clinical medical postgraduates from a medical university were investigated by basic information questionnaire and symptom Checklist-90 (SCL-90). Logistic regression was performed for data analysis. Excel 2010 was used for data entry, and SPSS 22.0 was used for statistical analysis.Results:The scores of each factor were as follows: somatization=1.24±0.44, compulsion=1.62±0.64, interpersonal sensitivity=1.4±0.54, depression=1.45± 0.64, anxiety=1.37±0.56, hostility=1.31±0.50, fear=1.18±0.42, paranoia=1.27±0.51, psychosis=1.25± 0.46, others=1.36±0.53. Besides, 169 (27.2%) people had positive mental health symptoms, and the top three symptoms were compulsion, depression and interpersonal sensitivity. The results of multivariate logistic regression analysis showed that grade, professional satisfaction, postgraduate study motivation and family education style were the influencing factors of mental health status of postgraduates in medical colleges and universities.Conclusion:The mental health status of postgraduates in medical colleges is worse than before. According to the influencing factors, targeted measures should be taken to improve the mental health level of postgraduates.
ABSTRACT
Objective To study the clinical effect of interventional therapy and cryosurgery by bronchoscopy in the treatment of bronchial tuberculosis.Methods 70 cases with bronchial tuberculosis were randomly divided into two groups 35 cases in each group.The drug treatment group was treated by internal medicine,and the combination therapy group was treated by the interventional therapy of the bronchus mirror on the basis of the drug treatment group.The total effective rate,the improvement time of cough and dyspnea,the number of treatment,the quality of life of patients were compared between the two groups.Results The total effective rate of the combination therapy group was higher than the drug treatment group (94.24％ vs 77.14％,x2 =4.200,P =0.04).The improvement time of cough and dyspnea in the comprehensive treatment group was shorter than those in the drug treatment group,the treatment times was less than that in the drug treatment group[comprehensive treatment group:(7.51 ± 1.41) d,(4.51 ± 1.61) d,(5.62 ± 1.21) times;drug treatment group:(9.39 ± 2.77) d,(5.39 ± 2.57) d,(7.61 ± 2.59) times;t =8.213,9.153,10.242,all P =0.00].Before treatment,the life quality scores between the two groups had no significant difference (P ＞ 0.05).After treatment,the improvement of quality of life in the combination therapy group was more significant[before treatment and after treatment of combination therapy group:physiological function:t =15.539,P ＜ 0.001;emotional function:t =11.789,P ＜ 0.001;social function:t =8.753,P ＜ 0.001.Before treatment and after treatment of drug treatment group:physiological function:t =10.128,P ＜ 0.001;emotional function:t =8.132,P ＜ 0.001;social function:t =6.931,P ＜ 0.001.After treatment,combination therapy group compared with drug treatment group:physiological function:t =7.433,P ＜ 0.001;emotional function:t =4.692,P ＜0.001;social function:t =3.297,P ＜ 0.001].Conclusion The clinical efficacy of bronchoscopic interventional cryotherapy in the treatment of bronchial tuberculosis is effective,it can effectively improve the clinical symptoms,improve lesions absorption,shorten symptoms subsided time,reduce the number of treatment,it is helpful to improve the quality of life of patients and worthy of popularization and application.
ABSTRACT
Objective To explore the correlation between the genetic dissimilarity and heterozygosity of mates and the patho?genicity of Schistosoma japonicum in the definitive host. Methods By using seven microsatellite loci markers,S. japonicum genotyping of sixteen pairs randomly mated was performed,the genetic dissimilarity and heterozygosity were calculated between the mates,and the correlation between the genetic dissimilarity and heterozygosity of the mates and the pathogenicity of S. japon?icum in the definitive host was evaluated. Results There was a significant correlation between the genetic similarity of S. ja?ponicum mates and the mean number of eggs per worm pair in the liver and intestinal tissue (r = 0.501 6 ,P 0.05;r=0.265 3,P>0.05,respectively)and the average diameter of granuloma in the liver(r=-0.272 7,P>0.05),respec?tively. There was no correlation between the heterozygosity of the mates and all the pathological parameters of S. japonicum in the definitive host(P > 0.05). Conclusions There is the correlation between the genetic dissimilarity of the mates and the pathogenicity of S. japonicum in the definitive host,and the genetic dissimilarity is greater,pathogenicity is weaker. There is no correlation between heterozygosity of the mates and the pathogenicity of S. japonicum in the definitive host.
ABSTRACT
Objective To retrospectively analyze the effect of two kinds of biological agents in volume -re-duced bullae .Methods 11 patients who suffered from bullae were operated under large C-arm locating ,and infused two kinds of biological agents through micro catheter of fibreoptic bronchoscopy .All of them were randomly divided into the two groups .The biological agents in group A were fibrinogen and diluent thrombin , and that of group B was Porcine Fibrin Sealant Kit .In group A,the micro catheter with diameter of micro thread less than 1.2mm was placed in bullae through fibreoptic bronchoscope ,and then the 2mL lidocaine,5 ml fibrinogen,and double of 500u diluent thrombin were inproperorder injected through micro catheter .In group B,the Porcine Fibrin Sealant Kit was injected at the same method,and then the suspension fluid was exacted .The operation time was recorded ,and then the clinical efficacy and incidence rate of complications were compared .Results The operation time of group A was 5-15 minutes, and that of group B was 6-20 minutes.For all the patients ,4 cases were totally effective ,2 cases were significantly effective,and 2 cases were totally non-effective.The total effective rate was 81.82%(9/11).The incidence rates of common complications in group A and B were 52.38%(22/42),58.33%(14/24),respectively,the difference was not significant (χ2 =0.22,P>0.05).Moreover,there were no serious complications in all cases .Conclusion The security and effect of two kinds of biological agents might be well enough ,but in view of less cases ,they were worth to further popularized and applied in clinical practice .
