Objective To use self-efficacy theory to intervene patients with chronic obstructive pulmonary disease (COPD),and assess its efficacy on the self management level of COPD patients.Methods 106 COPD patients hospitalized in the respiratory department of a certain hospital from October 2011 to April 2012 were randomly divided into the control group and the intervention group.Each group consisted of 53 patients.Two groups of patients received routine respiratory treatment and nursing.But patients in the intervention group were also systematically intervened under the guidance of Bandura self-efficacy theory.The self-management level of both groups of patients were assessed before the treatment and six weeks after the treatment respectively.Results The self-management level of the intervention group were significantly better than that of the control group after intervention.Conclusions Self-efficacy theory can improve the self-management level of patients with COPD.

Objective To report deep venous thrombosis (DVT) after greater saphenous vein ligation and stripping and to evaluate diagnosis,treatment and prophylaxis. Methods The clinical characteristics, diagnosis and treatment of 12 inpatients with postoperative DVT were analyzed retrospectively. Results Of these 12 cases there were 7 cases of central type DVT,2 cases of peripheral DVT,and 3 cases of mixed type DVT.Secondary pulmonary embolism was complicated in 2 cases.Clinical symptoms in these 10 cases of proximal DVT were all severe.Catheter-directed thrombolysis(CDT) through the ipsilateral popliteal vein with protective(IV)CF was applied for these 10 cases.Of 10 cases,femoral vein was found ligated in 1 case,which was repaired under open surgery. Residual greater saphenous vein thrombus extending into deep vein was proved and managed by successful thrombolectomy in one case.Cockett syndrome were found as the causes in the other 8 cases,6 cases were treated with balloon dilatation angioplasty and endovascular stenting of the iliac vein.The 2 cases of with distal DVT were treated by anticoagulation therapy.All patients were cured. Conclusions Cockett syndrome,femoral vein injury and too long residual greater saphenous vein are common causes of DVT after greater saphenous vein ligation and tripping.Careful selection of cases,correct diagnosis,standard operative manipulation,early ambulation were all important in the prevention of DVT after great saphenous vein varix procedure.

Objective To study the sonographic features of papillary thyroid carcinoma (PTC) associated with cervical lymph nodes metastasis for early diagnosis and prediction of the invaded cervical lymph nodes. Methods The sonographic features of 170 patients with pathologically confirmed PTC in First Afifliated Hospital of Harbin Medical University between 2011 and 2013 were retrospectively reviewed. There were 59 cases with neck lymph nodes metastases and 111 cases without neck lymph nodes metastases. Receiver operating characteristic (ROC) curve was aaplied to analyze the cut-off values of resistance index (RI) and peak systolic velocity (PSV) for judging the presence or absence of cercical lymph node metastasis. The Chi-square test and rank sum test were used to compare the different sonographic features between each group. The Logistic regression analysis was used to obtain the relevant factors of PTCs with cervical lymph node metastasis. Results ROC curve analysis showed that the cut-off values of RI and PSV were 0.735,13.95 cm/s. The primary tumor diameter, the existence of halo, the involvement of thyroid upper pole, the microcalciifcation, the blood suply classiifcation and the RI, PSV were statistically signiifcantly different between PTCs with and without cervical lymph node metastasis, whereas no statistical signiifcance was detected between the primary tumor echo pattern, boundary and the longitudinal/transveral ratio between the metastatic and nonmetastatic group. Logistic regression analysis showed that the PTC primary tumor diameter and PSV were independent factors coorelated with cervical lymph node metastasis. Conclusion Some sonographic features of PTC are closely correlated with lymph nodes metastasis, which are valuable in predicting the cervical lymph nodes metastasis in patients with PTC pre-operatively.

Objective To establish a rat model of glioma for MRI study.Methods Fischer 344 rats were inoculated with F98 glioma cells in caudate nucleus by stereotaxic procedure.MRI scanning and pathology examination were performed to observe the tumor growth on 6,8,10,12,and 14 d, respectively,after inoculation and their survival was also analyzed.Results After inoculation,tumors were found in all rats by MRI as early as 6 days.Most of rats died on 14 d after inoculation.The volume of tumor increased as the inoculation time lengthened.The tumor volume measured by MRI was larger than actual size by autopsy,but the both correlated positively(r=0.91,P

Objective To observe activated cerebral areas during the task of writing in second language by early and late acquisition bilinguals and explore the neuropsychological mechanism. Methods Twelve subjects were divided into group of early acquisition high proficiency bilinguals(EAHP) and group of late acquisition high proficiency bilinguals(LAHP). Each subject carried out the task of pseudo-writing and English writing. After functional imaging,statistical parametric mapping was used to compare data of the two tasks through paired- t test in both two groups. A conjunction analysis was conducted between the two groups also. Areas where the metabolism of glucose changed were analyzed. Then, the corresponding images about activated cerebral regions were obtained.Results Cerebral areas where the metabolism of glucose increased in EAHP: bilateral middle frontal gyrus( Z=4.35/2. 01 ), bilateral cerebellum ( Z = 2.97/2.53 ) and left head of caudate nucleus ( Z = 3.07 ), etc. Cerebral areas where the metabolism of glucose increased in LAHP: right superior frontal gyrus(Z=4.06), right cerebellum( Z=4.63), left putamen(Z=2.70) ,etc. Cerebral areas where the metabolism of glucose increased in compared data of LAHP with data of EAHP: right frontal gyrus ( Z = 2.92 ), right temporal lobe( Z = 2.31 ), etc. Conclusion Extensive cerebral cortex and subcortical structures participate the process of writing in the second language. Age of bilingual acquisition is one of the factors affecting cerebral localization of writing in second language.

The effects of dietary supplementation with Clostridium butyricum on growth performance and humoral immune response in Miichthys miiuy were evaluated. One hundred and fifty Miichthys miiuy weighing approximately 200-260 g were divided into five groups and reared in 15 tanks with closed circuiting culture system. The animals were fed 5 diets: basal diet only (control) or supplemented of the basal diet with C. butyricum at doses of 10(3) (CB1), 10(5) (CB2), 10(7) (CB3) or 10(9) (CB4) CFU/g. Compared with the control, the serum phenoloxidase activity was significantly increased by the supplementation (P<0.05), acid phosphatases activity was increased significantly (P<0.05) at the doses of 10(9) CFU/g. Serum lysozyme activity peaked at dose of 10(7) CFU/g and in the skin mucus at dose of 10(9) CFU/g. Immunoglobulin M level in the serum and skin mucus was increased except at dose of 10(3) CFU/g (P<0.05). The growth at the dose of 10(9) CFU/g was higher than that of the control (P<0.05). It is concluded that supplementation of C. butyricum can mediate the humoral immune responses and improve the growth performance in Miichthys miiuy.
