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.

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 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.

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 evaluate the therapeutic effects of aminoguanidine(AG) on cerebral ischemia-reperfusion damage in rats. Methods The intravascular thread models with 2 h of occlusion and 22 h of reperfusion were made in the rats.The brain infarction size and the degree of blood brain barrier(BBB) disruption in the ischemic regions were evaluated by staining with 2,3,5-triphenyl tetrazolium chloride and observing with Evans blue fluorescence microscope.HE staining was utilized for observing neutrophil infiltration. Results The brain infarction(volume,) the area of BBB disruption and the degree of neutrophil infiltration were dramatically decreased in the treatment group as compared to the control group(P

BACKGROUND:Airway epithelial regeneration can effectively inhibit submucosal hyperblastosis and the occurrence of obliteration. Studies demonstrated that ventilation could accelerate the regeneration of airway epithelium. OBJECTIVE:To establish and improve an orthotopic tracheal transplantation model and to further observe the effects of ventilation on trachea in alogeneic mice. METHODS:C57BL/6 mouse's tracheal served as donor, and BALB/c mouse's tracheal as recipient. This experiment contained two groups. In the experimental group, the membranous part of trachea was longitudinaly dissected in two donors and sutured into an enlarged trachea, which was implanted in the recipient. In the control group, donor's trachea was implanted into the recipient in situ. Samples were obtained and detected at 28 days after surgery. RESULTS AND CONCLUSION: Hematoxylin-eosin staining results demonstrated that compared with the control group, wel-differentiated ciliated epithelium was visible in the epithelial lamina of tracheal lumen, accompanying a few non-ciliated single or stratified squamous epithelium, mild submucosal fibrosis and inflammatory cel infiltration. Morphological analysis revealed that ciliated epithelial proportion in the experimental group was higher than in the control group (P < 0.05). The ratio of lamina propria to the tracheal cartilage, submucous fibrous tissuearea and the degree of lymphocyte infiltration were lower in the experimental group than in the control group (P < 0.05). Immunohistochemical staining demonstrated that the transplanted tracheal epithelium in both groups was recipient epithelial phenotype. Results verified that a modified orthotopic tracheal transplantation model was successfuly established. The increased ventilation of the tracheal alografts can accelerate the differentiation of tracheal epithelium. The wel-differentiated airway epithelium inhibited the proliferation of fibroblast.

PurposeTo evaluate the value of dual-source CT angiography (DSCTA) in the diagnosis of carotid atherosclerosis, and to explore the relationship between carotid atherosclerosis and diabetes mellitus (DM).Materials and Methods 145 patients with ischemic stroke were divided into DM group (n=80) and non-DM group (n=65). All patients underwent DSCTA. The location and characteristic of carotid atherosclerosis were analyzed using curve planE reconstruction (CPR), maximum intensity projection (MIP), multi-plane reformation (MPR) and volume rendering (VR). The differences between two groups were analyzed.Results Compared with non-DM group, the body mass index and high blood cholesterol were higher in DM group (t=6.197,P<0.05;χ2=8.372,P<0.01). The incidence of carotid atherosclerosis and vulnerable plaques were also higher in DM group than non-DM group (χ2=11.617 and 9.388,P<0.01). There was no significant difference between DM group and non-DM group in the location of carotid atherosclerosis (χ2=0.160, 0.509, 0.419 and 0.016,P>0.05). Carotid atherosclerosis was more common in carotid bifurcation and carotid artery siphon.Conclusion DSCTA can demonstrate the location and characteristics of carotid atherosclerosis in ischemic stroke patients with diabetes mellitus. Diabetes is a risk factor for the formation of carotid atherosclerosis, especially vulnerable plaques.

A selective precolumn derivatization liquid chromatography-tandem mass spectrometric (LC-MS/MS) method for the determination of glucosamine in human plasma and urine has been developed and validated.Glucosamine was derivatized by o-phthalaldehyde/3-mercaptopropionic acid.Chromatographic separation was performed on a Phenomenex ODS column (150 mm × 4.6mm,5μm) using linear gradient elution by a mobile phase consisting of methanol (A),and an aqueous solution containing 0.2％ ammonium acetate and 0.1％ formic acid (B) at a flow rate of 1 mL/min.Tolterodine tartrate was used as the internal standard (IS).With protein precipitation by acetonitrile and then the simple one-step derivatization,a sensitive bio-assay was achieved with the lower limit of quantitation (LLOQ) as low as 12 ng/mL for plasma.The standard addition calibration curves suitable for clinical sample analysis showed good linearity over the range of 0.012-8.27 μg/mL in plasma and 1.80-84.1 μg/mL in urine.The fully validated method has been successfully applied to a pharmacokinetic study of compound glucosamine sulfate dispersible tablets in health Chinese volunteers receiving single oral doses at 500,1000 and 1500 mg of glucosamine sulfate,as well as multiple oral doses of 500 mg t.i.d.for 7 consecutive days.
