2.A Survey about Psychosomatic Symptoms and Related Psychosocial Factors of Nursing Students in Military School
Chinese Mental Health Journal 2002;0(08):-
Objective:To study the relationship between psychosomatic symptoms and psychosocial factors of nursing students in military school.Methods:469 nursing students of a military medical school were investigated by SCL-90,EPQ,PSSS,Coping style inventory and self-esteem scale and so on.Results:Nursing students had lower SCL-90 score than the norm of Chinese female and that of military medical students.Their SCL-90 score correlated with EPQ-E、EPQ-L negatively and EPQ-N、EPQ-P positively.It also correlated with passive coping style positively; with positive coping style,self-esteem negatively.Conclusion:Nursing students of military school have less psychosomatic symptoms than medical students.The influential factors are similar to other populations.

Objective To analyze the clinical features and risk factors of migraine patients with white matter le-sions (WMLs). Methods One hundred ten clinically diagnosed migraine patients who underwent magnetic resonance im-aging (MRI) scans from October, 2010 to August, 2013 were enrolled in Shandong Provincial Hospital. One hundred ten migraine patients were divided into two groups:WMLs group and non-WMLs group based on the presence or absence of WMLs in MRI scans. The clinical features of the patients and location and number of WMLs were investigated. Noncondi-tional multivariate stepwise logistic regression after univariate analysis was used to analyze the data. Odds ratio (0R) and 95 confidence interval after adjustment for possible confounding variables were calculated. Results①There were 36 patients with WMLs among the 110 migraine patients. The incidence of WMLs in migraine patients was 32.7%. The WMLs in migraine patients were predominantly present in the frontal and parietal lobes (59.1%). ② Compared with non-WMLs group, there were significant increases in disease duration (5.3±3.7 vs. 7.6±4.9, P﹤0.01), frequency of head-ache attack (3.5 ± 2.3 vs. 4.6 ± 2.2, P﹤0.05), aura (18.9%vs. 36.1%, P﹤0.05) and family history of migraine (12.2%vs. 44.4%, P﹤0.01) in WMLs group.③The independent risk factors of WMLs in migraine patients were family history of mi-graine (OR=5.995), aura (OR=3.067) and long disease duration (OR=1.165). Conclusions Family history of migraine, au-ra and disease duration are the predictive risk factors of WMLs in migraineurs.

Objective To evaluate the reliability and validity of a medication dependence questionnaire in mi?graineurs of the Chinese version. Methods One hundred fifteen migraine patients with drug dependence syndrome were included and their clinical data were then collected. All the subjects were interviewed with the medication dependence questionnaire in migraineurs of the Chinese version. The reliability and validity of the questionnaire were evaluated ac?cording to test-retest reliability and internal consistency reliability, and the content validity and construct validity respec?tively. Results The test-retest reliability of the questionnaire items was 0.725~1.000 except item 11 (0.558) and item16 (0.443). The internal consistency coefficient of the questionnaire was 0.820, internal consistency coefficient of each di?mension was above 0.7. Every item score was positively correlated with corresponding dimension score (r=0.595~0.962). Seven factors with latent roots greater than 1 could explain 76.3%of total variance, and these factors were relatively pow?erful in related items. Conclusions The medication dependence questionnaire in migraineurs of the Chinese version shows preferable reliability and validity. Thus, this is a promising assessment tool to evaluate the medication dependence in Chinese migraineurs in future clinical practice.

Objective To observe the effect applicated of endoscopic sinus joint laryngoscope in laryngeal microsurgery.Methods 68 patients with laryngeal lesions were randomly divided into the multi-mirror combination group (34 cases) and the single laryngoscope group (34 cases).The multi-mirror combination group was taken with laryngeal microsurgery under endoscopic Joint laryngoscope.The single laryngoscope group was only taken with laryngeal microsurgery under laryngoscope.The efficacy and surgical situation of the two groups were compared.Results The total effective rate of the multi-mirror combination group was 97.06%,which was significantly higher than that of the single-laryngoscope group (85.30%) (x2 =4.031,P < 0.05).Compared with the case of surgery and complications and recurrence rate,the multi-mirror combination group was superior to the single laryngoscope group (all P < 0.05).Conclusion The endoscopic joint laryngoscope has the function of expanding the scope of the operative field and increasing the focus and clarity,and also has the advantages of small traumatic for patients,fewer complications,low recurrence rate,easy operation and high accuracy.

Choroidal metastasis is one of the most common malignant tumors inside the eyes. It causes pain, hypopsia and some other related symptoms. It reduces the quality of the patients' life. It's significant for the patients to be detected and treated early, therefore they will have better vision and longer life. The treatments of choroidal metastasis are developing quickly. Both the vitreous cavity injection of targeted drug and gene therapy are hot topics of research. This paper summarizes the etiology, development, diagnosis and treatment of choroidal metastasis nowadays.
