[ Objective] To discuss the characteristics of death among elderly people aged 60 years and above in Shanghai, who were classified into different age groups, and to provide a basis for making public health policy. [ Methods] On the basis of the data covering whole population death registry system in Shanghai, data on the elders aged 60-plus was collected and classified into 3 age groups according to WHO standards for descriptive analysis. [ Results] The crude death rate among the elders aged 60-plus in shanghai in 2014 was 3 001.76/105 ,accounting for 88.37%of the total mortality.The crude death rate of male was higher than that of female in each age group.The main causes of death in 60-74 age-group were cancer and coronary heart disease ( CHD) which had shorter course of disease with worse prognosis. The main causes of death in 75-89 age-group were cardiovascular and cerebrovascular diseases and chronic obstructive pulmonary disease ( COPD) which had longer course.The main causes of death in 90-pluse group included functional degradation and accidental fall, apart from cardiovascular and cerebrovascular diseases and COPD.And 54.35%of the elders aged 60-plus died in hospital, while 34.12%at home,and 6.63%at nursing home.The proportion of death at home was higher in non-central urban area than in central urban area.And the proportion of death in hospital decreased with increasing age. [ Conclusion] The proportion of the elderly death was large in total mortality.As the characteristics of death varied in different age groups, government should adopt different prevention and control measures.Rational allocation of medical and rehabilitation resources, as well as terminal care, need more attention and exploration by all institutions concerned.

With the development of social economy and improvement of people's health condition， life expectancy continues to extend and people are more concerned about the quality of life. Nowadays people's attention has shifted from living longer lives to living healthier lives. Life expectancy can only reflect the length of life， but not the health condition and quality of life. Meanwhile， healthy life expectancy contains death and disability information， which comprehensively reflects the length and quality of life and evaluates the health status of the population comprehensively. Through literature search and review， the article summarized the research on healthy life expectancy in recent years， including the concept proposal， index development， calculation， and application progress of health life expectancy. The research methods of healthy life expectancy are summarized in order to provide academic reference for further research.

OBJECTIVETo exam the effect and safety of conventional acupuncture (CA) on cardiac arrhythmia.

METHODSNine medical databases were searched until February 2016 for randomized controlled trials. Heterogeneity was measured by Cochran Q test. Meta-analysis was conducted if I was less than 85% and the characteristics of included trials were similar.

RESULTSNine qualified studies involving 638 patients were included. Only 1 study had definitely low risk of bias, while 7 trials were rated as unclear and 1 as high. Meta-analysis of CA alone did not have a significant benefit on response rate compared to amiodarone in patients with atrial fibrillation (Af) and atrial flutter (AF) [relative risk (RR): 1.09; 95% confidence interval (CI): 0.79-1.49; P=0.61; I=61%, P=0.11]. However, 1 study with higher methodological quality detected a lower recurrence rate of Af in CA alone as compared with sham acupuncture plus no treatment, and benefits on ventricular rate and time of conversion to normal sinus rhythm were found in CA alone group by 1 study, as well as the response rate in CA plus deslanoside group by another study. Meta-analysis of CA plus anti-arrhythmia drug (AAD) was associated with a significant benefit on the response rate when compared with AAD alone in ventricular premature beat (VPB) patients (RR, 1.19, 95% CI: 1.05-1.34; P=0.005; I=13%, P=0.32), and an improvement in quality-of-life score (QOLS) of VPB also showed in 1 individual study. Besides, a lower heart rate was detected in the CA alone group by 1 individual study when compared with no treatment in sinus tachycardia patients (MD-21.84 [-27.21,-16.47]) and lower adverse events of CA alone were reported than amiodarone.

CONCLUSIONSCA may be a useful and safe alternative or additive approach to AADs for cardiac arrhythmia, especially in VPB and Af patients, which mainly based on a pooled estimate and result from 1 study with higher methodological quality. However, we could not reach a robust conclusion due to low quality of overall evidence.

Objective: To predict B cell and T cell epitopes of 22-kDa, 47-kDa, 56-kDa and 58-kDa proteins. Methods: The sequences of 22-kDa, 47-kDa, 56-kDa and 58-kDa proteins which were derived from Orientia tsutsugamushi were analyzed by SOPMA, DNAstar, Bcepred, ABCpred, NetMHC, NetMHC II and IEDB. The 58-kDa tertiary structure model was built by MODELLER9.17. Results: The 22-kDa B-cell epitopes were located at positions 194-200, 20-26 and 143-154, whereas the T-cell epitopes were located at positions 154-174, 95-107, 17-25 and 57-65. The 47-kDa protein B-cell epitopes were at positions 413-434, 150-161 and 283-322, whereas the T-cell epitopes were located at positions 129-147, 259-267, 412-420 and 80-88. The 56-kDa protein B-cell epitopes were at positions 167-173, 410-419 and 101-108, whereas the T-cell epitopes were located at positions 88-104, 429-439, 232-240 and 194-202. The 58-kDa protein B-cell epitopes were at positions 312-317, 540-548 and 35-55, whereas the T-cell epitopes were located at positions 415-434, 66-84 and 214-230. Conclusions: We identified candidate epitopes of 22-kDa, 47-kDa, 56-kDa and 58-kDa proteins from Orientia tsutsugamushi. In the case of 58-kDa, the dominant antigen is displayed on tertiary structure by homology modeling. Our findings will help target additional recombinant antigens with strong specificity, high sensitivity, and stable expression and will aid in their isolation and purification.
