Methods The insertion/deletion (I/D) polymorphism of ACE gene was detected by the polymerase chain reaction (PCR) in 43 patients with DCM and 53 normal controls. The exons 13,14 of cardiac ?-MHC gene from 43 patients and 53 controls were amplified restrictively by using PCR. The amplified products of PCR were digested by restrictive en-donuclease DdeⅠ and NlaⅢ to identify the mutations at No. 8848 and 9124 nucleotide of ?-MHC gene. Results The frequency of ACE DD genotype and the frequency of the allele D was remarkably higher in individuals with DCM than those in normal control people ( P

Objective To assess the effects of gastric bypass versus medical therapy in patients with obesity and type 2 diabetes. Methods The Cochrane library, Embase, PubMed, Chinese biomedical literature database and Wanfang database up to April 2014 were searched. Randomized controlled trails(RCTs) of frequently-used bariatric surgery for obese patients with type 2 diabetes were included. Study selection, data extraction, quality assessment, and data analyses were performed according to the Cochrane standards. Results Four RCTs involving 157 patients in the gastric bypass groups and 152 patients in the medical therapy group were enrolled. Compared with medical therapy, gastric bypass for type 2 diabetes significantly decreased the levels of HbA1C(mean difference = -1. 85% , 95% CI -2. 15 ~ -1. 56, P< 0. 01), fasting blood glucose( standard mean difference = - 0. 90 mmol/ L, 95% CI-1. 24 ~ -0. 57, P<0. 01), body weight(mean difference=-23. 39 kg, 95% CI -29. 17 ~ -17. 61, P<0. 01), waist circumference(mean difference= -15. 36 cm, 95% CI -17. 51 ~ -13. 22, P<0. 01) and the dose of hypoglycemic medicine; while it increased the number of patients with HbA1C<6% (RR=5. 49, 95% CI 2. 22 ~ 13. 56, P<0. 01), the rate of adverse events(RR=1. 96, 95% CI 1. 42 ~ 2. 70, P<0. 01), and the level of high-density lipoprotein-cholesterol(mean difference=1. 24 mmol/ L, 95% CI 0. 64 ~ 1. 84, P<0. 01). Conclusions Gastric bypass surgery is more effective compared with medical therapy alone for obese patients with type 2 diabetes. Further intensive RCTs of high-quality in multiple centers with long-term follow-up should be carried out to provide more reliable evidences.

Ultraviolet light(UV)-sensitive disorders refer to a group of diseases due to damages to the nucleotide excision repair mechanism which cannot effectively repair DNA damage caused by ultraviolet radiation. The inheritance pattern of such diseases, mainly including xeroderma pigmentosum, Cockayne syndrome and trichothiodystrophy, is autosomal recessive and known to involve 13 genes. As proteins encoded by such genes are involved in DNA repair and transcription pathways. There is overlap between the symptoms of such diseases, and their genotype - phenotype correlations are quite complex. To facilitate genetic and prenatal diagnosis for such diseases, a summary of the research progress is provided, which mainly focused on mutation research and genotype - phenotype correlation studies. We also propose a strategy for their genetic diagnosis based on recent findings of our group.

Objective: This study aimed to analyze and summarize the implementation of the primary prevention program for stroke in Shanghai rural community and evaluate its preventive effect. Methods: A cluster sampling method was used to select approximately 50 000 community natural population from a town in Fengxian District of Shanghai. A primary stroke prevention program was established and implemented in the community from 2008 to 2010 and from 2012 to 2015. The prevention program inclueded stroke health education for the whole population, screening of high risk population of stroke, and therapeutic intervention and management plan for individuals aged≥50 years. The intervention measures were followed up every 2 months. From 2008 to 2015, new stroke cases were monitored dynamically and reviewed annually with classification of stroke diagnosis. The effect of community primary prevention of stroke program was evaluated by the dynamic changes in stroke incidence. Results: From 2008 to 2015, a total of 422 600 individuals were monitored, including 20 500 men and 217 600 women. In 2008, 7 828 individuals were screened and 2 129 individuals were at high risk of stroke were screened, with a high risk rate of 27.2%. In 2012, 2 877 individuals were screened, and 725 individuals were at high risk of stroke were screened, with a high risk rate of 25.2%. The standardized incidence of stroke in this community was 158.1, 105.4, 86.6, 77.6, 89.3, 77.4, 50.7, and 42.3 per 100 000 respectively. The overall incidence image roughly showed a downward trend except 2012(trend test P<0.01). There was no significant difference in the incidence of stroke between men and women in each year. The incidence of stroke increased significantly with age (trend test P<0.01). The age composition of stroke patients is slightly different between different sexes. The proportion of male patients with stroke aged <70 years was significantly higher than that of female patients with stroke, while the proportion of female patients with stroke age>70 years was significantly higher than that of male patients with stroke (P<0.01). Cerebral hemorrhage, cerebral infarction, and subarachnoid hemorrhage accounted for 20.76%, 75.14%, and 4.10%, respectively. Conclusion Based on lifestyle intervention and treatment and control of risk factors, screening high-risk individuals for therapeutic intervention in community population can significantly reduce the incidence of stroke.
