Han Jiangbo. Department of Theoretical Mechanics, Luoyang Industry College. Luoyang Since January 1982 we have relocated the insertion of a part of pectoralis major or deltoid muscle in the treatment of 5 cases of habitual dislocation of shoulder. After over a year of follow-up no recurrence of dislocation has been found in all the cases. The shoulder joint seemed to be stable, the range of movements increased, and disturbance in supination was corrected. The operative procedure was studied in fresh cadavers and human skeleton. Studies on mechanical model of shoulder joint, with theoretical calculation of changes in pronation after muscle displacement, showed that movements of pronation were remarkably increased after displacement of partial pectoralis major and deltoideus. It could also compensate the weatened subscapularis.

Objective:To investigate therapeutic effect of cisplatin sequential recombinant human vascular endostatin thoracic perfusion in treatment of malignant pleural effusion.Methods:A total of 80 patients with malignant pleural effusion in Maoming People's Hospital from January 2018 to February 2021 were enrolled, and all patients were divided into 2 groups according to the random number table methods, each group with 40 cases. The control group was treated with small-bore catheter minimally invasive drainage combined with cisplatin thoracic perfusion, and the study group was treated with small-bore catheter minimally invasive drainage combined with cisplatin sequential recombinant human vascular endostatin thoracic perfusion. And then the clinical efficacy, expressions of vascular endothelial growth factor (VEGF) expression, pain degree and adverse reactions were compared of both groups.Results:The treatment efficacy rate of the study group was higher than that of the control group [90% (36/40) vs. 75% (30/40)], and the difference was statistically significant ( χ2 = 5.04, P < 0.05). After treatment, the level of VEGF in pleural fluid and serum of the study group was lower than that of the control group [(304±106) pg/ml vs. (598±159) pg/ml,(103±43) pg/ml vs. (189±49) pg/ml], and the difference was statistically significant ( t = 6.62, P < 0.001; t = 6.23, P < 0.001). After treatment, the visual analogue scale (VAS) score of the study group was lower than that of the control group [(3.7±0.3) scores vs. (4.4±0.7) scores], and the difference was statistically significant ( t = 2.10, P < 0.05). The incidence of adverse reactions including stethalgia, fever, nausea and vomiting in both groups had no statistically significant differences (all P > 0.05). Conclusions:Cisplatin sequential recombinant human vascular endostatin thoracic perfusion combined with small-bore catheter minimally invasive drainage can effectively ameliorate clinical symptoms, inhibit the expression of VEGF, and alleviate pain degree with no serious adverse reactions in patients with malignant pleural effusion.

OBJECTIVETo test validity and reliability of Personality Diagnostic Questionnaire-fourth vision (PDQ-4) and a self-report DSM-IV axis-II personality disorder (PD) assessing instrument as well as to study the prevalence of personality dysfunction among students of first grade senior high schools in Beijing.

METHODSAmong 100 PD patients, 91 non-PD patients with mental disorder, and 100 normal people, sensitivity, specificity and consistency were tested by ICD-10 criteria. By means of stratified cluster sampling, 10 039 students from 25 senior high schools in urban and rural in Beijing were studied using PDQ-4.

RESULTSPDQ-4 had high sensitivity and moderate specificity for most axis II disorders when compared with ICD-10. Among different samples, PDQ-4 yielded various levels of sensitivity and specificity. Meanwhile, the test-retest consistency was 92.2%. Among 130 adults, the total PDQ-4 score was 18.9 +/- 9.8. The score in males was 20.6 +/- 10.1, versus 17.1 +/- 9.2 in females with significant difference (t = 2.09, P < 0.05). Scores in different age groups were 21.5 +/- 10.5 in age 16 - 25, 16.9 +/- 11.3 in age 26 - 35, 16.4 +/- 9.7 in age 36 - 45, 16.2 +/- 7.9 in age 46 - 55, and 20.0 +/- 7.8 in age 56 and over respectively. No statistical significant difference of scores at age groups was found (F = 2.07, P > 0.05). Among 9 547 students, the total PDQ-4 score was 25.4 +/- 9.6, being significantly higher than that of adult sample. The prevalence of personality dysfunction was 5.6%. Regarding the distribution of personality dysfunction in gender, residential area, and type of school, data showed that the prevalence rates were higher in males, rural area and lower-ranking schools.

CONCLUSIONPDQ-4 can be used as a PD screen tool in psychiatric institutions and community settings. The distributions of personality dysfunction in Beijing were significantly different on gender, residential area and type of schools. Attention should be paid to personality dysfunction during adolescence.

Objective To compare the effects of different anesthetics on the recovery of neurologi-cal function after intracranial aneurysm embolization. Methods One hundred patients of both sexes with aneurysmal subarachnoid hemorrhage, aged more than 18 yr, with body mass index of 18. 5-24. 0 kg∕m2 , of American Society of Anesthesiologists physical status Ⅱ or Ⅲ and WFNS grade Ⅰ-Ⅳ, with the thick-ness of subarachnoid hemorrhage more than 4 cm, were divided into 2 groups (n= 50 each) using a random number table: propofol group (group P) and sevoflurane group (group S). After anesthesia induction, group P received intravenous infusion of propofol 100-300 μg·kg-1 ·min-1 , while the end-tidal sevoflu-rane concentration was maintained at 1. 4％-3. 5％ in group S. Immediately before induction (T0 ), imme-diately after the end of induction (T1 ), immediately after successful embolization of aneurysm (T2 ) and at 1, 2, 3 and 5 days after surgery (T3-6 ), central venous blood samples were collected for determination of plasma neuron-specific enolase and S100β protein concentrations by enzyme-linked immunosorbent assay. The development of postoperative cerebral vasospasm and delayed ischemic neurological deficit was recorded. The patients were followed up, and the Glasgow outcome score and occurrence of newly developed cerebral infarction were recorded within 6 months after surgery. Results There was no significant difference in the concentrations of plasma neuron-specific enolase and S100β protein at each time point, incidence of postop-erative cerebral vasospasm and delayed ischemic neurological deficit, or Glasgow outcome score and inci-dence of newly developed cerebral infarction within 6 months after surgery between two groups (P>0. 05). Conclusion Propofol and sevoflurane exert no effect on the recovery of neurological function after intracra-nial aneurysm embolization.
