Object To assess the genetic diversity among ten natural populations in Ophiopogon japonicus (L f ) Ker Gawl and O. bodinieri Levl (Liliaceae) in Sichuan Province Methods Forty random decamer primers were screened for Random Amplified Polymophic DNA (RAPD) fragments Results Based on cluster analysis of 515 DNA bands amplified by 11 primers, a DNA molecular dendrogram was established, and the relationship of the populations and seeds between O japonicus and O bodinieri was set up Conclusion 1 Distinct genetic differences and extensive genetic diversity are presented among the samples The genetic differences are related to morphological differences, but not to geographic regions; 2 Quite genetic differences are presented between O japonicus and O bodinieri, it suggests that they have farther relationships

Objective To detect the change and clinical significance of homocysteine (Hcy),hypersensitivity C response protein (hs-CRP) and hypersensitivity troponin I (hs-TnI) in patients with acute myocardial infarction (AMI).Methods Ninety-six cases of AMI were selected as the research group and 60 cases of coronary heart disease without AMI were enrolled in the control group.Blood samples were collected to measure the contents of serum Hcy,hs-CRP and hs-TnI.ROC curve was drawn and Logistic regression model was established to analyze the role of each index alone and combined detection in the diagnosis of AMI.Results The levels of Hcy,hs-CRP and hs-TnI in the research group were significantly higher than those in the control group (Hcy: (29.29±7.65) mol/L vs.(17.23±4.68) mol/L;hs-CRP: (15.47±5.01) mg/L vs.(9.21±3.15) mg/L;hs-TnI: (40.88±9.18) ng/mL vs.(7.34±2.12) ng/mL,t=2.78,8.66,34.36,P<0.05).The area under the ROC curve of Hcy,hs-CRP,hs-TnI were 0.802 (95%CI(0.729~0.874)),0.71(95%CI(0.62~0.792)),0.929 (95%CI(0.891~0.967)),respectively.The area under the combine detection curve was 0.971 (95%CI,0.950~0.992).The sensitivity of Hcy,hs-CRP and hs-TnI in the diagnosis of AMI were 79%,57%,87%,respectively,the specificity of the three groups were 72%,70%,90%,the sensitivity and specificity of combined detection were 96% and 88%.Conclusion Combined detection of Hcy,hs-CRP and hs-TnI plays a better role in the diagnosis of AMI than that of Hcy,hs-CRP,hs-TnI alone and has a high specificity and sensitivity in the diagnosis of AMI.

Bioimprinting is a new developed technique to improve the characteristics of enzymes.Bioimprinting by lauric acid was conducted to improve the esterification activity of lipase PS in sol-gel immobilization process with methyltrimethoxysila(MTMS) and tetramethoxysila(TMOS) as the precursors.Results generated by checking the esterification activity and scanning electron microscope showed that bioimprinting can enhance the specific activity and thermal stability of lipase PS.The bioimprinting system was optimized by orthogonal experiment,and the optimal condition for lipase bioimprinting is water/silane molar ration(R) 12,polyethylene glycol(PEG) 120?l,and lauric acid 0.15 mmol.Compared with the free enzyme and the non-imprinted enzymes,the specific activity of imprinted enzymes has been improved 44.3 fold and 2.4 fold,respectively.Imprinted lipase show better thermal stability,and the relative activity is 58% after incubated in 80 ℃ for 0.5 h,while no activity was detected for the free enzyme.

Objective To investigate the prevalence and risk factors of mild cognitive impairment (MCI) among the old people in Chongqing, China. Methods From October to November, 2015, 1850 persons more than 60-year-old in Chongqing were cluster sampled. They were investigated with self-made general situation questionnaire, Mini-Mental State Examination (MMSE), Instrumental Activity of Daily Living Scale (IADL) and Geriatric Depression Scale (GDS) through face-to-face interview. Enumeration data were tested withχ2 test and multiple Logistic regression. Results MCI prevalence was 11.73%in the old people in Chongqing, and various with the residential re-gions, ages, marital status, literacy, career, smoking, drinking, seafood-eating, egg-eating, exercising, intensive labor, low intensity of labor, housework, outdoor activities, Mahjong/chess/cards playing, TV-watching/radio-listening/newspaper-reading, social activities, obesity, hy-pertension, diabetes, stroke, hyperglycemia, cerebrovascular insufficiency and depression (χ2>4.092, P<0.05). According to multiple Logis-tic regression, living in rural areas, aging, celibacy, obesity, hypertension and depression were the risk factors of MCI;while middle school and above years of schooling, mental workers, smoking cessation, frequent seafood-eating and egg-eating, exercising, daily intensive labor and low intensity of labor, daily and sometimes housework, daily and weekly outdoor activities at least once, daily Mahjong/chess/cards playing and daily TV-watching/radio-listening/newspaper-reading were the preventing factors. Conclusion The morbidity of MCI is high in the old people in Chongqing. It is necessary to take effective intervention in view of the related factors of MCI as early as possible, to delay or prevent the development of MCI to dementia.

Objective To investigate the prevalence status and risk factors of mild cognitive impairment (MCI) in old people in pension facilities in Chongqing, China. Methods From October to November, 2015, the people above 60 years old in four pension facilities in Chongqing were cluster sampled. They were interviewed with Mini-Mental State Examination, Instrumental Activity of Daily Living Scale, self-made general situation questionnaire for the elderly and the Geriatric Depression Scale. Results There were 25 MCI patients identified in 84 old people selected, with the prevalence of 29.76%. MCI prevalence was different with the factors such as genders, educational levels, economical status, smoking, eating freshwater fish frequently, participating in outdoor activities frequently, playing Mahjong/chess/cards fre-quently, watching TV/listening to broadcast/reading newspaper frequently, participating in social activities frequently, having religious be-liefs, suffering high blood pressure (χ2>4.271, P<0.05). Based on multivariate Logistic regression analysis, male was the protective factor (OR=0.055, 95%CI:0.005~0.618), while high blood pressure was the risk factor (OR=8.281, 95%CI:1.278~53.646) to the MCI. Conclu-sion MCI is prevalent in old people in pension facilities in Chongqing, which needs intervention targeted to the risk foctors.

OBJECTIVE: To explore the relation between diabetes mellitus and clinicopathological factors and the incidence of radiation pneumonitis in patients with non-small cell lung cancer. METHODS: The data of 332 patients with non-small cell lung cancer, who were admitted to the Department of Oncology of Third Xiangya Hospital of Central South University between January 2007 and August 2009, were collected retrospectively. The patients were divided into a diabetes mellitus (DM) group (n=45) and a non-diabetes mellitus (NDM) group (n=287). The clinicopathological factors were compared between the two groups. The patients who received radiotherapy were further divided into a diabetes mellitus (DMR) group (n=33) and a non-diabetes mellitus group (NDMR) group(n=287), and the incidence of radiation pneumonitis was compared. RESULTS: A total of 45 patients (13.55%)developed diabetes mellitus. There was significant difference in the body-weight, age and hypertension (P<0.05), while no significant difference in the pathologic factors, such as tumor pathological type, degree of differentiation, and classification of malignant tumors (TNM) stage between the two groups(P>0.05). No significant difference in the irradiation area was found between the DM group and the NDM group(P>0.05). The incidence of radiation pneumonitis in the DMR group was 42.42%(14 out of 33), while 21.31%(39 out of 183) in the NDMR group, with significant difference in the incidence of radiation pneumonitis between the DMR group and the NDMR group(P<0.05). The risk value in the DMR group was 2.721 folds (95%CI, 1.253-5.910) that in the NDMR group in patients with non-small cell lung cancer companied with diabetes mellitus. CONCLUSION Diabetes mellitus is the risk factor of radiation pneumonitis for patients with nonsmall cell lung cancer who receive radiotherapy.
