Objective To investigate the relationship between single nucleotide polymorphisms (SNPs) of UGT1 A6 and aspirin response in a cohort of Chinese Han population.Methods A total of 323 ischemic stroke patients consecutively registered in Nanjing Stroke Registry Program from September 2011 to October 2014 were enrolled.Three SNPs (rs6759892,rs2070959 and rs1105879) of UGT1A6 were genotyped in these ischemic stroke patients.Association of genotypes and aspirin response was evaluated by generalized linear model.Indicated with the inhibition rate of platelets,aspirin response was assessed by thromboelastograph.Results The mutation allele (G) of rs2070959 was positively related to platelets inhibition (β =0.084,P =0.010,Pcorrected =0.029),especially in male (β =0.098,P =0.006,Pcorrected =O.019).The dominant models of rs6759892,rs1105879 were also modestly related to aspirin response (P=0.015,Pcorrected=0.046 in both SNPs) in male.Thus the polymorphisms of UGT1A6 showed a relationship with aspirin response,especially in males.Conclusions The results indicated that genetic polymorphism of UGT1A6 might have an effect on individuals' aspirin response,especially in males.These findings can help clinicians to optimize the antiplatelet therapy for ischemic stroke patients.

The blocking effect of selenium-enriched malt (Se-malt) on AFB1-in-duced UDS was reported. When the rats were fed with food containing lppm Se in form of Se-malt for two weeks, the UDS values of leukocytes treated with 6?10-7M AFB1 in vitro was decreased from 54.8 ?14.0 opm/106 WBC to 35.1?10.0 cpm/106 WBC (p

Stroke has become the leading cause of death in Chinese residents. As the cornerstone of the primary and secondary prevention of ischemic stroke, aspirin can prevent the occurrence and recurrence of ischemic stroke in a certain extent. However, some patients stil have vascular events after taking aspirin regularly or higher platelet aggregation rate. This phenomenon is caled aspirin resistance or aspirin low reactivity. This article reviews the occurrence, detection methods, and treatment measures of aspirin resistance in patients with ischemic stroke.

Objective Toinvestigatetheeffectofrehabilitationrobothandontheupperlimbmotor functioninpatientswithstrokeandhemiplegia.Methods Theeffectsoftraditionalrehabilitation therapy or robot rehabilitation treatment of 15 stroke patients with hemiplegia were analyzed retrospectively. There were 4 females and 11 males. According to the group order,they were divided into either a robot rehabilitation group (n=8 )or a general rehabilitation group (n =7 ). The patients of the general rehabilitation group received general rehabilitation training at the Department of Rehabilitation Medicine for 4 weeks,3 times a week,and 30 min for each time. At the same time,they also conducted family rehabilitation training,5 times a week,once for 1 h;the patients of the robot rehabilitation group received the general rehabilitation training for the same length of time as the general rehabilitation group,and they also performed robot rehabilitation training,5 times a week,once for 1 h. The patients of both groups were evaluated with the modified Ashworth scale (MAS )scores,Fugl-Meyer motor assessment of the upper extremity(FMA-UE),andWolfmotorfunctiontest(WMFT)beforeandaftertreatment.Results Compared with before training,the MAS score of the robot rehabilitation group was decreased significantly after four weeks of training. The time in WMFT was shortened significantly and the function score was improved obviously. The scores of upper extremity,hand score,and total FMA score in FMA-UE were improved significantly,and there were significant differences (all P <0. 05 ),while there were no significant differences in various indicators in the general rehabilitation group (all P>0. 05). Comparing the effects after four weeks of rehabilitation in both groups,the robot rehabilitation group was superior to the general rehabilitationgroupforthehandscoreinFMA-UE(allP<0.05).Conclusion Therehabilitation robot hand effectively lowered the upper limb spasticity. It has significant effect for recovery motor function of hand;however,it did not have a significant effect for motor rehabilitation on wrist.

Objective To investigate the effect of X-ray irradiation on the expression of free ubiquitin in the serum, small intestine, and heart tissues of C57 BL/6N mice. Methods The amount of free ubiquitin protein in the serum and tissue homogenates was analyzed quantitatively with ELISA and Western Blotting assay. The mRNA expressions of free ubiquitin in the tissues were detected by RT-PCR. Results At 24 or 48 h after radiation, the free ubiquitin level in the serum and small intestine tissue increased asymptotically with increasing of radiation dose (F=183?1, 435?3, P <0?01). After 5 and 10 Gy X-ray irradiation, the concentration of serum free ubiquitin increased asymptotically with the extended response time (F=131?4, 442?9, P<0?01). Compared with the normal control group, at 24 h after 10 Gy X-ray irradiation, the expressions of free ubiquitin protein and mRNA in small intestine tissue were significantly up-regulated (t= -18?7, -10?1, P<0?01). However, there was no difference in the expressions of free ubiquitin protein and mRNA in the heart tissues between irradiated and nonirradiated groups (t = -2?0, 3?1, P >0?05). Conclusions Because of the high expressions of free ubiquitin protein in the radiosensitive mice tissues, X-ray radiation could increase the concentration of free ubiquitin in serum. The changes of free ubiquitin may be related to cellular radiosensitivity and tissue injury.

OBJECTIVETo investigate the association between microRNA (miR)-146a gene polymorphisms and susceptibility to gastrointestinal cancer.

METHODSPubMed, Medline and Ovid full text databases, China Journal Full-text Database (CNKI), Articles Database and Chinese Biomedical Literature Database were researched to retrieved literatures about the association between miR-146a gene polymorphism and susceptibility to gastrointestinal cancer published from July 2010 to March 2014. Modified Jadad quality score was used to evaluate the quality of the literatures and Stata 11.0 software was used to analyze and calculate OR value of the following 5 different genotypes: allele (G vs. C), the dominant genetic model (GC+GG vs. CC), a recessive genetic model (GG vs. GC+CC) and homozygote (GG vs. CC) and heterozygote (GC vs. CC) to assess the association.

RESULTSA total of 16 studies were enrolled, including 7090 cancer patients and 9928 healthy controls. Meta-analysis showed that people with G allele was more susceptible to gastrointestinal cancer than those with C(gastric cancer: OR=1.1,95% CI:1.04-1.17, P=0.001, colorectal cancer: OR=1.09,95% CI:1.01-1.18, P=0.020); dominant model (GC+GG) was more susceptible to gastric cancer than CC (OR=1.12, 95% CI:1.02-1.22, P=0.016); recessive genetic model GG was more susceptible to gastrointestinal cancer than CC+GC (gastric cancer: OR=1.16, 95% CI:1.05-1.27, P=0.004, colorectal cancer: OR=1.13, 95%CI:1.00-1.28, P=0.047); GG homozygote was more susceptible to gastrointestinal cancer than CC (gastric cancer: OR=1.20, 95% CI:1.06-1.35, P=0.003, colorectal cancer: OR=1.19, 95% CI:1.01-1.41, P=0.042). Dominant genetic model GC+GG and CC in colorectal cancer as well as heterozygous GC and CC in gastrointestinal cancer were not significantly different(P>0.05).

CONCLUSIONmiR-146a cancer susceptibility gene polymorphism is closely associated with gastrointestinal cancers.

Objective To survey the status of knowledge and management capability on diabetic kidney disease (DKD) among general practitioners (GPs) in community health service centers (CHCs) of Shanghai.Methods A questionnaire survey was conducted among 152 GPs from 6 CHCs in 3 districts of Shanghai during May 2015 and March 2016.Results In the current survey,138 (90.8％) valid questionnaires of DKD knowledge and 152 (100.0％) valid questionnaires of DKD management capability were retrieved.The overall accuracy rate of DKD knowledge was 60.2％ (1 246/2 070);the accurate rates of epidemiology,diagnosis,treatment,and community management knowledge were 62.7％ (173/276),62.8％ (520/828),60.6％ (502/828)and 35.5％ (49/138),respectively.There were significant differences in accuracy rates of treatment related questions among GPs with different years of working (P =0.032 2);but no significant differences were observed in accuracy rates of 4 aspects related questions among GPs with different education and professional title (P ＞0.05).Among 152 participants,113 (74.3％) responded to conduct DKD screening in clinic work;97(63.8％) chose renal function,86 (56.6％) chose urine routine and 86 (56.6％) chose urinary microalbumin for screening,respectively.The top three answers to "how to intervene patients with DKD" were blood glucose control(107,70.4％),medication of ACEI or ARB (77,50.7％),and high-quality low protein diet (68,44.7％).Conclusion The knowledge and management capability on DKD among GPs in CHCs are insufficient.The capability of diagnosis and treatment of DKD should be improved by joint efforts of GPs,trainers,and community health administrators.

Endothelial cell injury is a major contributor to cardiovascular diseases.The 2,3,5,4’-Tetrahydroxystilbene-2-O-β-D-Glucoside (TSG) contributes to alleviate human umbilical vein endothelial cells (HUVECs) injury through mechanisms still know a little. This study aims to clarify the TSG effects on gene expression (mRNA and microRNA) related to oxidative stress and endoplasmic reticulum stress induced by H2O2 in HUVECs. We found that TSG significantly reduced the death rate of cells and increased intracellular superoxide dismutase activity. At qRT-PCR, experimental data showed that TSG significantly counteracted the expressions of miR-9-5p, miR-16, miR-21, miR-29b, miR-145-5p, and miR-204-5p. Besides, TSG prevented the expression of ATF6 and CHOP increasing. In contrast, TSG promoted the expression of E2F1. In conclusion, our results point to the obvious protective effect of TSG on HUVECs injury induced by H2O2, and the mechanism may through miR16/ATF6/ E2F1 signaling pathway.
