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 effects of various media, salt intensity, and organic components on the growth of Salvia miltiorrhiza adventitious roots and the synthesis of tanshinone ⅡA and protoca-techuic aldehyde. MethodsThe adventitious roots were obtained through tissue culture by manipulation of various media, salt intensity, and organic components and the contents of tanshinone ⅡA and protocatechuic aldehyde were determined by HPLC. ResultsThe effect of media MS, LS, B5, White, and SH on adventitious roots of S. miltiorrhiza was observed. Adventitious roots grew better under high salt intensity while secondary metabolite biosynthesis was accelerated under low salt intensity in MS basal medium.The reciprocity of five organic components had significant effect on root growth; glycin favored the synthesis of tanshinone ⅡA; scarcity of one of inosital, glycin, VB1, and VB6 inhibited the synthesis of protocatechuic aldehyde. ConclusionMS Basal medium is used for adventitious root culture. The results show that salt intensity and organic components have significant effects on adventitious root culture of S. miltiorrhiza and secondary melabolite synthesis.

Objective To study the effects of carbon, nitrogen, and phosphate sources on the growth of Salvia miltiorrhiza adventitious roots and the contents of tanshinone ⅡA and protocatechuic aldehyde. Methods The adventitious roots were obtained through tissue culture by manipulation of carbon, nitrogen, and phosphate sources and the contents of tanshinone ⅡA and protocatechuic aldehyde were determined by HPLC. Results Carbon, nitrogen, and phosphate sources were necessary for the culture of S. miltiorrhiza adventitious roots. The highest times of root multiplication were achieved at sucrose level of 30 g/L after 20 d culture, 60 g/L sucrose and low level sucrose were favorable for biosyntheses of tanshinone ⅡA and protocatechuic aldehyde, respectively. The highest root yield and tanshinone ⅡA content on day 25 were obtained by intermittent sugar adding during cultivation, and the production of adventitious roots and tanshinone ⅡA were 2.3-and 2.4-fold compared with those of control, respectively. The maximum root growth rate, contents of tanshinone ⅡA and protocatechuic aldehyde were achieved while NH4+-NO3-was 1∶4, 1∶4, and 1∶1, respectively when concentration of total nitrogen source was kept at 60 mmol/L. To compare with the control group, changing of KH2PO4 concentration could favor for the adventilious root growth, but high KH2PO4 concentration inhibited tanshinone ⅡA biosynthesis. ConclusionThe results show that various carbon, nitrogen, and phosphate sources have the significant effects on adventitious root culture of S. miltiorrhiza. The best carbon source and its concentration, nitrogen and phosphate sources for the growth of S. miltiorrhiza adventitious root and the synthesis of secondary metabolite are confirmed.

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:To investigate the relationship of family history , psychosocial factors of PD (Parkinson's Disease) in a rural population in north China. Methods: A case control study was conducted in rural population in China. Cases (n=77) have been diagnosed by a two-phase screening by neurologists and interviewers in May, 2000. Controls (n=154), randomly selected from the same cohort, who were matched with patients (control/cases ra-tio=2) for sex, age (?5 years). Information of participants' characteristics came from the interview in 2001. Data was analyzed by using conditional logistic regression by SAS 6.12. Results: Family history (OR=13.54) .negative life events (OR=3.02), interpersonal communication (OR=2.10) were associated with a significantly elevated risk for the onset of PD. Conclusion: These results indicate that family history, psychosocial factors were risk factors of PD.

Objective To investigate the effects and the possible mechanisms of berberine in human cervical cancer Hela cell line in vitro. Methods Cell growth rate was determined with MTT assay. TUNEL was used to examine cell apoptos rate. The expression of COX-2 and Bcl-2 proteins were detected by immunocytochemistry method. Results Berberine induced cytotoxicity and apoptosis in human cervical carcinoma Hela cells in time-dependent and dose-dependent manner. Berberine could down-regulated the Bcl-2 protein expression of Hela cells,but had no significant influence in the expression of COX-2 protein. Conclusion Berberine can inhibit Hela cell growth of cervical carcinoma and induce apoptosis in vitro. Down-regulation of the Bcl-2 protein expression may be involved in berberine-induced apoptosis of HeLa cells.
