Objective By comparing the prevalence of mental disorders and social demographic characteristics, to analyze the influencing factors of mental disorders in Xiamen city residents. Method Using multi-stage stratified cluster random sampling, 12 071 subjects aged 18 years and older were identified in Xiamen city. Eventually 10 764 subjects completed the survey, including 4 957 males, 5 807 females, 8 588 urban population and 2 176 rural population. The subjects were screened with the expanded version of GHQ-12, the Structured Clinical Interview for DSM-Ⅳ-TR as a diagnostic tool, and made a determination whether they had mental disorder and specific diagnosis. Result The overall prevalence of mental disorders in Xiamen city was lower than that in other provinces and cities; it was only 3.46%(Shandong province 19.48%, Zhejiang province 17.27%, Qinghai province 18.04%, Hebei province 16.24%, Tianshui city 17.90%, Chengde city 17.71%, Baoding city 13.62%). The one of most common mental disorders was the alcohol use disorders in various provinces and cities, except in Xiamen city. The constituent ratio of Xiamen residents surveyed was 79.78%for urban, higher than those of other provinces and cities (Shandong province 24.91%,χ2=6 624.955,P<0.001;Zhejiang province 32.95%,χ2=3 601.752, P<0.001;Qinghai province 23.55%,χ2=4 991.289,P<0.001;Hebei province 15.95%,χ2=11 547.016,P<0.001;Tianshui city 16.05%,χ2=6 484.483,P<0.001;Chengde city 15.60%,χ2=2 930.811,P<0.001;Baoding city 11.80%,χ2=6 973.770,P<0.001). Most residents of Xiamen enjoyed at least one kind of health insurance (83.06%), higher than those of other provinces and cities (Zhejiang province 23.30%,χ2=8 868.617,P<0.001;Hebei province 8.68%,χ2=17 434.576,P<0.001;Tianshui city 11.20%,χ2=10 862.305, P<0.001;Chengde city 8.69%,χ2=5 884.478,P<0.001;Baoding city 9.54%,χ2=10 728.632,P<0.001). Conclusion The overall current prevalence of mental disorders in Xiamen city residents was lower than those of other provinces and cities. The reasons may be that there was higher degree of urbanization, better health care, no heavy drinking habits and other factors. There might be other protective factors which need to be further studied.

AIM: To explore the clinical efficacy of traditional Chinese acupuncture combined with conventional rehabilitation therapy onoculomotor nerve palsy patients.METHODS: From May 2005 to September 2012, 110 cases ofoculomotor palsy were divided into treatment group and control group with 55 cases in each group according to different methods of treatment. The control group received rehabilitation therapy, the treatment group received acupuncture combined with rehabilitation therapy. Before and after 8wk treatment, the light reflex, diopter case, eye fissure width, and eye movement to improve the overall efficiency of the situation were observed between the two groups.
RESULTS: After treatment of 8wk, light reflex, diopter case, eye fissure width, and eye movement therapy total effective rate of the treatment group were all better than the control group (P<0. 05);The eye movement improved in the treatment were 47 cases which accounting for 85-5%, in the control group there were 36 cases which accounting for 65. 5%, the treatment group had a higher improvement (P<0. 05).
CONCLUSION: Acupuncture therapy combined with rehabilitation training method significantly reduces the oculomotor nerve palsy in patients with clinical symptoms and improves the patient's quality of life.

Thyroid function [triiodothyronine(T3), thyroxine(T4), free T3(FT3), free T4(FT4),and thyroid stimulating hormone (TSH) ] were tested by radioimmunoassay in 56 depressive patients with attempted suicide, 85 patients without suicide attempt and 40 healthy subjects (controls).The serum levels of T3 and FT3 in the patients with attempted suicide were lower than those in the patients without suicide attempt and the controls ( F = 4.937 and 5.01 1, both P ＜ 0.05 ).The lower serum levels of T3 and FT3might be the risk factor of suicide in depressive patients.

Objective To explore the characteristics of both clinical symptoms and thyroid function between depressive patients with and without attempted suicide behavior. Methods Depressive patients were divided into two groups. The first group was composed of patients with attempted suicide behavior (n = 56) and the second group without attempted suicide behavior ( n = 85 ). Thyroid function (FT3, FT4 )were determined by radioimmunoassay method. The patients were evaluated by symptom checklist 90 (SCL90). Results The score of depressive factor in the group with attempted suicide [(2. 90 ± 1. 01 ) score]was higher than that of the group without attempted suicide [(2.51±0.77) score] ( ( t =2. 127, P =0. 036). The serum level of FT3 in the group with attempted suicide [(3.92 ±0. 52) pmol/L] was lower than that of the group without attempted suicide[(4.18 ±0.71) pmol/L] ( t =-2.219, P =0.028).Conclusions There were certain characteristics on clinical symptoms of depressive patients with attempted suicide. The low serum levels of FT3 might play an important role in the risk of suicide in depressive patients.

BACKGROUND: With the fast development of computer technology,biomechanical study of cervical vertebra is not limited in animal or human corpses,because computer model can provide a more accurate model.OBJECTIVE: To develop a three-dimensional,finite element model of a human C2-7 based on previous studies,and to provide experimental data for the biomechanical study of the cervical spine.METHODS: A normal young 28-year-old male,without obvious cervical spondylosis history,was selected,and C-spine X-rays at posteroanterior,oblique,and over extension and over flexion position were performed to deplete cervical spondylosis.The CT scanning images were dealed with Software Mimics and Geomagic to obtain the finite element,and software ANSYS was used to study the response of the model.Under a 1.8 N·m segmenal movement and force displacement response were observed and compared with abroad experimental results.RESULTS AND CONCLUSION: The new finite element model was composed of six vertebrae(C2-7),five discs(C2/3-6/7)and main ligaments.The model consisted of solid elements with 23 348 nodes and 215 749 units.The results of the biomechanical study were better correlated with the available experimental data.It indicates that the finite element model of cervical spine at C2-7 can be used to imitate the biomechanical experiment of cervical spine.

Objective To investigate the relationship between ultrasonographic features of papillary thy-roid carcinoma(PTC)and lateral cervical lymph node metastasis (LCLNM).Methods A total of 449 eligible ca-ses with 633 PTC nodules was selected and divided into two groups:LCLNM group included 135 nodules(91 pa-tients);Without metastatic groups included 498 nodules(135 patients).Ultrasonographic features of PTC nodules and the relationship with LCLNM were analyzed by χ2 test and logistic regression analysis .Results In univariate analysis,the significant factors were male,age<45yrs,multifocal,maximal diameter(d>1 cm),multi-microcal-cificaltion(d<2 mm),mixed flow,wider than tall,CCLNM,extrathyroid extension,located in upper(P<0.05 or P<0.017).Multivariate analysis showed that multi -microcalcificaltion(d<2 mm),wider than tall,CCLNM,ex-trathyroid extension,located in upper pole were predictive factors of LCLNM (P<0.005,OR=1.626,2.644, 0.479,2.579).Conclusion High-frequency ultrasound can accurately describe the sonographic appearance of thyroid nodules;it can be used to remind the risk of LCLNM before operation ,and will be informative for the treat-ment of surgery .

Objective To investigate the changes in intrapulmonary shunting during controlled hypotension induced by sodium nitroprusside(SNP)in patients undergoing naso-endoscopic operation.Methods Forty ASAⅠorⅡpatients of both sexes(23 male,17 female)aged 16-50 yrs weighing 50-75 kg undergoing naso-endoscopic operation under general anesthesia with muscle relaxation and mechanical ventilation were studied.Radial artery was cannulated for direct BP monitoring and blood sampling.Right internal jugular vein was cannulated and the catheter was advanced into right ventricle.Blood sample taken from right ventricle was used as mixed venous blood instead of blood from pulmonary artery.ECG,MAP,HR and P_(ET) CO_2 were continuously monitored during operation Cardiac output was monitored with noninvasive cardiac function monitor(NC-COM.)based on impedance principle.SNP infusion was started at the beginning of operation at 1-3?g?kg~(-1)?min~(-1) and was then adjusted.MAP was reduced by 30%-40% and maintained at this level until the end of operation.Blood samples were taken from artery and right ventricle simultaneously before SNP infusion(T_1,baseline)at 30 and 60 min of hypotension(T_2,T_3)and at 20 min after BP returned to the baseline level(T_4)for blood gas analysis.Qs/Qt was calculated.Results Qs/Qt was significantly increased during controlled hypotension at T_2 and T_3 as compared to the baseline value(P＜0.01)and returned to the baseline level at T_4.HR was increased and cardiac output and stroke volume was significantly reduced during hypotension as compared to the baseline value.Conclusion The intrapulmonary shunting is increased and the hemodynamics is depressed during SNP-induced controlled hypotension and they return rapidly to baseline level after SNP is discontinued.No hypoxemia develops during SNP- induced hypotension.

Objective To investigate the alteration of peripheral tissue`s temperature of the coagulation zone of microwave ablation in brain tissue, and to provide experimental evidence for clinical application. Methods Twelve canines were treated by microwave ablation in brain tissue. Each was ablated for 180 s with microwave output power of 20 W, 30 W, and 40 W. During the operation the peripheral temperature at the distance of 0.5 cm, 1.0 cm, 1.5 cm and 2.0 cm from the ablation center was recorded respectively. The ultrasound was performed 1 hour after the operation, and then the animals were executed and the microscopic changes of the ablation lesion were observed. Results Eleven canines suffered well for the ablation, while 1 presented abnormal respiration during the operation and died 2 hours later. During the operation, the temperature of the area 0.5 cm from the center rose signiifcantly, with the maximum temperature was (96.40±1.46)℃at the power of 20 W, and 100℃at the power of 30 W and 40 W. The temperature of the area 1.0 cm from the center rose faster, with the maximum temperatures at different powers all above the 46℃. The temperature of the area 1.5 cm from the center rose slower, with the maximum temperature below 46℃at the power of 20 W and 30 W and above 46℃at the power of 40 W. The maximum temperatures of the area 2.0 cm from the center at different powers were all below 46℃. The difference of the maximum temperature at different distances (1.0 cm, 1.5 cm, and 2.0 cm from the center) was signiifcant (F=776.78, 2640.64 and 3025.53, all P<0.05). The length and width of the ablation lesion as well as the area of edema increased with the power. At the power of 20 W, 30 W, and 40 W, the length of the ablation lesion was (29.3±1.8) mm, (32.7±2.1) mm and (34.2±2.4) mm, the width was (22.5±1.5) mm, (23.7±1.7) mm and (27.1±2.0) mm, and the width of the edema zone was (2.3±0.4) mm, (2.6±0.4) mm and (2.7±0.5) mm. The differences of the length and width of the ablation lesion at different powers were signiifcant (F=11.46, 14.49, both P<0.01). The difference of the edema area at different powers was insigniifcant (F=1.94, P=0.169). Conclusions Microwave ablation is a safe therapeutic modality. However, the shorter distance from the ablation center and greater ablation power give rise to larger ablation lesion, higher maximum temperature, and faster temperature increase. Therefore, 2.0 cm from the ablation center is a safe area.
