Objective:To translate the English version of Edmonton Frail Scale into Chinese version and to test its reliability and validity.Methods:The translation and cross-cultural adaptation of the English version of Edmonton Frail Scale were generated by Beaton's translation and back-translation method. From April to August of 2019, at the department of geratology of the First affiliated Hospital of China Medical University in Shenyang, a sample of 303 hospitalized elderly adults who met the inclusion and exclusion criteria were selected via convenience sampling method to test its psychometric properties.Results:The scale level content validity index and item level content validity index of the Chinese version of the Edmonton Frail Scale were both 1.0. The criterion validity between the Chinese version of Edmonton Frail Scale and the Tilburg Frailty Indicator was 0.723 ( P<0.01), confirmed by Pearson correlation coefficients. Using the Tilburg Frailty Indicator as an external criterion, the Edmonton Frail Scale showed satisfactory diagnostic accuracy for frailty (area under the curve=0.924). The optimal cut-point for frailty was 6 (sensitivity: 77.6%, specificity: 94.7%). More frail individuals were recognized by the Chinese version of Edmonton Frail Scale among older and female participants than their counterparts( P<0.05). The Cronbach'α of the Chinese version of Edmonton Frail Scale was 0.599, the test-retest reliability within a 7-day interval of the scale was 0.822. Conclusions:The Chinese version of Edmonton Frail Scale presents good validity and reliability and can apply to Chinese hospitalized elderly people.

Objective To investigate the risk factors of color-ectal cancer and to provide scientific basis for prevention of colorectai canc-er. Methods A 1:1 matched case-control study was carried out in Dalian including 200 cases with colorectal cancer and 200 controls. We analyzedthe data with the univariate analysis and mutivariate conditional logistic re-gressiou,theu calculated the Odds Ratio and the 95% confidence. Results Conditional logistic regression showed that history of constipation, family history of other tumor,intake much bloat food ten yeats ago and easily an-gry were the risk factors of colorectal cancer, and intake much fresh vegeta-bles ten years ago was the protective factors of colorectal cancer. One way analysis showed that following factors were the risk factors of coloroctal cancer:there were pollution factor around home 10 years ago, belly CT test,sleep over twelve o'clock at night,family history of coloroctal cancer, history of pries, appendicitis and the operation history of appendicitis, intake much fry and bake food,seashell and animal liver before ten years ago,of-ten feel strew, don't like to communicate with others,pessimism,don't harmonization with colleague. And iutaking much chicken meat, bean prod-ucts,garlic ten years ago,doing exercise and the frequency of exercise,high income were the protective factors of colorectal cancer. Conclusion Coloroctal cancer was the result of many factors. But the incidence of that in Dalian city was related to history of constipation, family history of other tumor, easily angry, intake less fresh vegetables and intake much bloat food ten years ago.

Objective To study the signal transduction pathway of norepinephrine (NE)-induced expressions of oncogenes c-fos and c-myc in the rat heart. Methods mRNA levels of c-fos and c-myc in the left ventricle of the Langendorff-perfused rat heart was quantitated by reverse transcription and polymerase chain reaction (RT-PCR). Results NE increased the expressions of c-fos and c-myc while the effects of NE on the expressions of c-fos and c-myc were blocked by ? 1-adrenergic blocker prazosin (5?10 -6 mol/L) completely. Neomycin (5 mmol/L) and ruthenium red (10 ?mol/L) decreased the NE-induced c-fos and c-myc mRNA levels. Conclusion NE can induce the expressions of oncogenes c-fos and c-myc in the ventricle mediated by ? 1-adrenergic receptor. The signal transduction pathway of NE-induced c-fos and c-myc expressions may be associated with inositol phosphates-Ca 2+ system and diacylglycerol-protein kinase C system.

Subclinical thyroid dysfunction including subclinical hypothyroidism and subclinical hyperthyroidism, subclinical hypothyroidism is more common in the general population. Subclinical thyroid dysfunction may increase the incidence of risk factors of stroke, like hypertension, diabetes melitus, dyslipidemia, atherosclerosis, atrial fibrilation, homocysteinemia and so on. Subclinical thyroid dysfunction may be associated w ith the outcomes in patients after acute ischemic stroke.

Objective To study the clinical effect of sequent anti-coagnlation treatment of ischemic cerebral vascicular disease. Methods 28 frequent TIA and 30 progressive ischemic stroke patients were studyed.The patients with progressive stroke were given gener- al anti-coagnlation and other common therapy firstly.Those who got worse clinical symptoms and signs received uarfafin orally.The effects of before and after uarfarin therapy were compared.Results Of all the 58 patients,24.1% patients recovered completely,50% improved obviously,17.3% improved and 8.6% had no effects,before and after takeing medicines the score Comparison about neurological impair- ment degree has a highly signifient difference(P

Objective: To investigate the Ventral Pallidrm′s function of cardiovascular adjustment by observing the changes of the rats′blood pressure. Methods:Ten SD rats′blood pressure were respectively observed through a catheter in one of the common carotid arteries after unilateral Ventral Pallidum stimulation by certain concertration,certain volume glutamate solution under stereotaxic guidance. Results:Glutamate stimulation on Ventral Pallidum caused elevation of the rats′blood pressure,thechanges were significant. Conclusion:Ventral Pallidum has a role in regulating blood pressure. It belongs to behavior related pattern and sympathetic regulated.

Objective To study the association between vitamin D status and bone mineral density(BMD) in aged people.Methods A total of 118 patients admitted in cadre department aged (77.7±11.2) years were selected from July 2010 to May 2011.The BMD at lumbar spine (L1-4) and femoral neck was measured by dual energy X-ray absorptiometry (DEXA).According to BMD,patients were divided into two groups:osteoporosis and non-osteoporosis group.The data of serum 25-hydroxy vitamin D3 [25(OH)D3]concentration,height,weight and age of patients were collected at the same time.Results The age and body mass index (BMI) in osteoporosis group were (81.6 ±5.6) years and (22.5 ± 4.0 ) kg/m2,while (79.4 ± 6.9 ) years and (24.1± 4.2 ) kg/m2 in nonosteoporosis group (t=1.80 and -2.01,P＞0.05).The concentrations of serum 25(OH)D3 in two groups were(21.6± 10.3)nmol/L and (32.0± 13.8) nmol/L,respectively(t=-4.20,P＜0.01).And there were 95.3 ％ (41/43 )and 81.3 ％ (61/75) of patients whose serum 25 (OH)D3 level were ≤50nmol/L in osteoporosis and non- osteoporosis group,respectively(x2 =4.58,P＜0.05).Furthermore,the 25 (OH) D3 level was positively correlated with BMD at femoral neck(r=0.22,P＜0.05),but not correlated with BMD at L1-4 ( r=0.18,P＞0.05).Conclusions Vitamin D status is correlated with BMD at femoral neck in aged people.

Objective: The aim of our study was to analyse the death cause and related factors of death in hospital of patients after cardiac valve replacement (CVR). Methods: Regression analysis of 34 patients' data was executed. Results: Death rate was 9.9 %, death cause: (1) L.ow cardiac output syndrome is the first complication and death cause (2.6 % ), which was closely related to cardiac function (grade Ⅳ ) before operation, LVEDD＞8.0 cm, LVEF＜0. 40, GR ＞80%, emergency operation, long time of arterial block, etc; (2) Ventricular tachycardia、 ventricular fibrillation is the second cause of death (2. 1%); (3) Respiratory failure (4) Post-operation hemorrhage inducing pericardial tamponade and shock; (5) Postoperation infection of replaced valve and brain complications. Conclusion: The success rate of operation can be increased by selecting patients strictly, improving operation methods, enhancing periopertive monitor.

0.05). Significant differences of post-operative VA, time of retinal detachment, and neurepithelial thickness were found (P0.05). Conclusions The time of retinal detachment and post-operative VA in patients with retinal detachment relate to the neurepithelial thickness detected by OCT. When the duration of retinal detachment becomes longer, the macular neurepithelium becomes thicker, the histomorphological changes increase, and the post-operative VA decreases.
