Objective To test the reliability and validity of the Chinese Version of the Depressive Cognition Scale (DCS) among the older people.Methods The sample consisted of 570 old people,collected by a demographic questionnaire,the Chinese version of DCS,and the Center for Epidemiological Studies Depression Scale (CES-D),then all the data was analyzed by SPSS 21.0.Results The item-to-total correlation coefficients of DCS ranged from 0.65 to 0.84 (P＜0.01),and the average coefficient was 0.77.The content validity index(CVI) was 0.88.The result of exploratory factor analysis (EFA) was that one factor explained 59.72％ of the total variances,and the concurrent validity between DCS and CES-D was positive related (r=0.24-0.82,P＜0.01).Regarding CES-D as the gold standard,the sensitivity was 84.7％ and the specificity was 90.7％.The inter-item correlation coefficients of DCS ranged from 0.40 to 0.73 (P＜0.01);the Cronbach α was 0.82,and the retest reliability (intra-class correlation coefficient,ICC) was 0.92 (95％CI=0.86-0.95,P＜0.01).Conclusion DCS is proved to be a reliable and valid instrument,and it can be used to assess the depressive cognition and screen the early depressive symptoms of Chinese old adults.

Objective To test the reliability and validity of the Chinese version of the sense of coherence (SOC) scale (13-items) among the older people.Methods A random sample of 1 032 old adults was selected from community in Jinzhou,Shenyang,Dalian of Liaoning.A demographic questionnaire,the SOC-13 scale,the WHO-5 and the Center for Epidemiological Studies Depression Scale (CES-D) were used to collect the data.All the data was analyzed by SPSS 21.0 and AMOS17.0.Results The item-total correlation coefficients of SOC-13 ranged from 0.625 to 0.760 (P＜ 0.01).The result of exploratory factor analysis (EFA) was that three factors explained 74.745％ of the total variances,and the CFA confirmed the hypothesized three-factor model.SOC scale had an ideal criterion(x2/df =2.908,CFI =0.975,GFI =0.949,NFI =0.963,IFI=0.975,RMSEA=0.061).Criterion related validity test showed that the total score of SOC-13 was negatively correlated with CES-D(r=-0.55,P＜0.01),and positively correlated with WHO-5 (r=0.73,P＜ 0.01).SOC-1 3 had a Cronbach's α of 0.916,the Guttman split-half coefficient was 0.828,and the retest reliability (intra-class correlation coefficient,ICC) was 0.872 (P＜0.01).Conclusion SOC-13 is a reliable and valid instrument,which can be used to measure the lever of sense of coherence among Chinese old adults.

Objective To adopt the cone beam computed tomography(CBCT) to analyze the bone thickness of infrazygomatic crest with different vertical skeletal facial types in teenagers.Methods Sixty teenagers of skeletal class were collected,including each 20 cases of high angle,average angle and low angle.The CBCT scanning data of oral maxillofacial region were collected.The bone thickness at different coronary slices in buccal side of infrazygomatic crest region at 13,15,17 mm above the maxillary occlusal plane was measured.The measured data were analyzed statistically.Results The bone thickness of infrazygomatic crest was gradually thinned from down to up,and the difference was statistically significant(P＜0.05);the bone thickness(except 3 points at 13 mm from maxillary plane) at each measured point in the high,average and low angle groups showed the change trend of low angle ＞average angle＞high angle,the difference was not statistically significant(P＞0.05).Conclusion In teenagers,the bone thickness of infrazygomatic crest in skeletal class Ⅱ is gradually thinned from cranial direction and rearward,the high angle is thinnest and the low angle is thickest.

Objective To investigate the clinical features, diagnostic criteria and treatment of primary pulmonary lymphoma (PPL). Methods 11 patients with PPL, the diagnosis of which was made with pathological study of biopsy specimen, admitted from 1997 to 2006 to General Hospital of PLA, were retrospectively analyzed. The data collected for the present study, combined with some references, were reviewed concerning the clinical characteristics, X-ray features, pathologic features, bronchoscopic observations, diagnostic criteria as well as treatment. Results PPL was a rare disease, and was hard to have a definite diagnosis for lack of specific clinical symptoms. The most common clinical symptoms of PPL were cough, chest distress, fever etc. X-ray features included solitary or multiple nodules, ground-glass opacity, filamentous shadow and consolidation shadow. Such signs could be seen at the same time, commonly accompanied with air bronchogram. No distinct changes could be found in bronchofibroscopy. Final diagnosis of PPL could be made when a CT guided biopsy was done, followed by pathological examination with immunohistological study, or study of the tumor after surgery. Surgical operation and chemotherapy were the major effective therapeutic approach for the treatment of PPL. Prognosis was favorable in patients with low degree of malignancy of the tumor. Conclusion The clinical characteristics and X-ray image of PPL are not specific. Misdiagnosis occurs commonly. The final diagnosis of PPL depends on the pathologic examination of the PPL tissue. Appropriate CT guided biopsy is necessary for an early diagnosis. Surgery as well as ancillary chemotherapy after operation could get satisfactory results.

Objective To investigate the changes in concentration of plasma von Willebrand factor (vWF) and the effects of heme oxygenase-1 (HO-1) in rabbits with endotoxin (ET)-induced acute lung injury (ALI). Methods Twenty four male New-Zealand rabbits were randomly assigned to three groups: control group, ET group and hemin-treatment group. Saline was iv. injected into the animals of control group; in animals of ET-treatment group ALI model was reproduced with endotoxin iv. injection (700 ?g/kg); animals of hemin-treatment group received intraperitoneal injection of heme for 2 days before ET challenge (40?mol/kg, 2 times per day). Arterial blood gas assay was performed and the plasma vWF concentration was determined with ELSIA at 0h (pre-experiment), 0.5, 1, 2 and 4h time points for the animals in all three groups. When the rabbits were sacrificed, the dry/wet weight ratio of lung and HO-1 (mean density) were determined and the pathological changes in lung tissue were examined. Results Compared with control group, the partial pressure of oxygen (PaO2) and oxygenation index (PaO2/FiO2) declined, meeting the diagnostic criteria of ALI, and plasma vWF concentrations increased obviously (P

Objective To evaluate the value of transvaginal ultrasound in the diagnosis of tubal pregnancy.Methods The retrospective analysis was made according to transvaginal ultrasound inspection on 77 patients and their sonographic appearance and ultrasonic diagnosis of tubal pregnancy proved by surgery and pathology.Results The two-dimensional sonogram mainly showed the adnexal masses and the liquid area opaca in the pelvic cavity.The masses were divided into three types:germ heart-beat type,gestational sac type,and uneven mixed mass type.According to distinctive two-dimensional sonographic appearance,the accuracy rates of transvaginal ultrasound in the diagnosis of rupture,nonrupture,and abortion tubal pregnancy were 87.23%,100%,and 34.62%,respectively.In combination with pelvic mass,indirect sign of effusion,and patient history,the accuracy rates of ultrasonic diagnosis in the above clinical classifications were 95.74%,100%,and 84.61%,respectively.The accuracy rate of the total ultrasonic diagnosis was 92.21%.Conclusions Transvaginal ultrasound has higher accuracy in the diagnosis of rupture and nonrupture tubal pregnancy,but it lacks distinctive sonographic appearance in the diagnosis of the majority of abortion tubal pregnancy,which is the main reason for affecting the accuracy of ultrasonic diagnosis of tubal pregnancy.
