Indirect fluorescent antibody test (IFAT) using frozen sections of Brugia malayi adult worms as antigen was employed in the diagnosis and epidemiological investigation of human filariasis. Sera were collected from 704 cases with bancroftian or malayan microfilaremia. the positive rate was 92.8-99.1%. Of 150 healthy people from non-endemic areas, only one showed a positive reaction (false positive rate 0.7%) (Table 1). This technique proved to be highly sensitive and specific for the diagnosis of filariasis and the antigen is easy to prepare. It might be used in sero-epidemiological investigation for the assessment of filariasis control.

OBJECTIVE To investigate dopamine level changes in the Nucleus Accumbens (NAc) of the limbic system by salicylate and the role of dopamine in the mechanisms of tinnitus.METHODS We recorded the change of dopamine before and after sodium salicylate injection in rats by microdialysis combined with electrochemical methodologies in the nucleus accumbens (NAc).RESULTS Salicylate produced significant increase in dopamine level in the NAc, to a maximum of (321±97)% of baseline and then remain stable. In contrast, saline only produced slight increase.CONCLUSION The increase of dopamine in the NAc may be related to the generation of tinnitus. The data in vivo provide direct evidence of the important role that the dopaminergic system plays in the generation of tinnitus.

Objective To study the effects of community-based rehabilitation on cerebral apoplexy patients with cognitive disorders.Methods 30 cases of cerebral apoplexy patients were enrolled according to relevant standards,who were given standard rehabihtation care in Community Health Service Center(training group) ,while another 30 similar cases from subordinate health service stations (control group) given only rehabilitation guidance once a week.Two groups were not do professional cognitive training.All patients were assessed with Mini Mental State Examination( MMSE), Fugl-Meyer Assessment(FMA) and modified Bathel index rating scale(MBI) to evaluate their cognition ,movement function and activity of daily living(ADL) before training as well as after 4-week and 8-week training.Results There was no signficant difference in cognition,movement functions and ADL between training group and control group before treatment(P>0.05).The differences in the assessment of Brounnstrom scale and MBI between two groups after 4-week training were not significant( P > 0.05 ).The scores of Fugl-Meyer scale, MMSE and Barthel index of the training group after 8-week training were significantly higher than those of control group( all P < 0.05 ).Conclusion Community-based rehabilitation training could improve the movement functions and ADL,and cognitive functions of cerebral apoplexy patients.

Emblic medicine is a popular natural source in the world due to its outstanding healthcare and therapeutic functions. Our preliminary results indicated that the quality of emblic medicines might have an apparent regional variation. A rapid and effective geographical traceability system has not been designed yet. To trace the geographical origins so that their quality can be controlled, an integrated spectroscopic strategy including spectral pretreatment, outlier diagnosis, feature selection, data fusion, and machine learning algorithm was proposed. A featured data matrix (245 × 220) was successfully generated, and a carefully adjusted RF machine learning algorithm was utilized to develop the geographical traceability model. The results demonstrate that the proposed strategy is effective and can be generalized. Sensitivity (SEN), specificity (SPE) and accuracy (ACC) of 97.65％, 99.85％ and 97.63％ for the calibrated set, as well as 100.00％ predictive efficiency, were obtained using this spectroscopic analysis strategy. Our study has created an integrated analysis process for multiple spectral data, which can achieve a rapid, nondestructive and green quality detection for emblic medicines originating from seventeen geographical origins.

Objective:To explore the association between resting heart rate(RHR) and all-cause mortality among the Chinese oldest-old aged more than 80.Methods:Using a total of seven surveys or follow-ups data (1998, 2000, 2002, 2005, 2008, 2011 and 2014) from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). A total of 17 886 elderly over 80 years old were selected as subjects, their resting heart rate were measured though baseline survey and the survival outcome and death time of the subjects were followed up. The subjects were divided into 6 groups according to their resting heart rate. Cox regression model was used to estimate the effect of resting heart rate on mortality risk. The interaction of age, gender and resting heart rate was also analyzed by likelihood ratio test.Results:The age of subjects M( P25, P75) was 92 (86, 100) years old, including 10 531 females (58.9%) and there were 13 598 participants died, the mortality rate was 195.5 per 1 000 person-years. Multivariate Cox regression analysis showed that compared to the control group (60-69 pbm/min), the hazard ratio of the elderly are 1.06 (95% CI: 1.02, 1.11), 1.09 (95% CI: 1.04, 1.15), 1.23 (95% CI: 1.14, 1.34), 1.25 (95% CI: 1.08, 1.44) in the group of RHR between 70-79, 80-89, 90-99 and ≥100 pbm/min and Pvalues are all less than 0.05. Likelihood ratio test showed that RHR and age had an interaction effect. ( P for interaction=0.011). Conclusion:The risk of all-cause death increased with the increase of resting heart rate and this relationship was stronger between the 80-89 years old people.
