T was genotyped by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)in all the patients.Results The occurrence of CR in this population was 23.3%(70/300).There was CYP3A4 894C/T polymorphism in the study population.The frequencies of the three kinds of genotypes(CC,CT,TT)in CR group and non-CR(NCR)group were 45.7%,50.0%,4.3% and 63.5%,31.7%,4.8%,respectively.The frequency of TT genotype was significantly higher in NCR group than that in CR group(OR=2.06,95% CI:1.201-3.547,P=0.020).C allele carriers were more likely to develop clopidogrel resistance compared with that of T allele carriers(OR=1.59,95% CI:1.037-2.442,P=0.023).Conclusion CYP3A4 gene 894C/T polymorphism is associated with the risk of CR,and C allele carriers may be a possible genetic susceptibility factor for patients with CR.

BACKGROUND:In recent years, research on tendinopathy is becoming a hot topic in the sports medicine and rehabilitation, and the extracelular matrix plays a considerable role in the occurrence, development and healing of tendinopathy.
OBJECTIVE: To explore the relationship between tendinopathy and the extracelular matrix.
METHODS: CNKI, VIP, CBM, Wanfang, PubMed and Embase were retrieved for articles related to colagen, protein, glycoprotein and matrix remodeling published since 2000.
RESULTS AND CONCLUSION:After tendinopathy, there are obvious changes in colagen, proteoglycans, glycoprotein and related enzymes; and these changes also affect the reconstruction and repair of tendinopathy. Currently, most of researches focus on the tendon rather than the bone-tendon junction. This means that there are no in-depth studies on the correlation between many important proteins and tendinopathy, and the effects of exercise intervention.

Objective To investigate the clinical value of echocardiography combined with genetic testing in the fetal cardiac rhabdomyoma. Methods Thirty-three fetal cardiac rhabdomyoma cases diagnosed by fetal echocardiogram in Beijing Anzhen Hospital from Jan. 2011 to Oct. 2015 were enrolled in a retrospective analysis. The results of other examination and pregnancy outcomes of them were followed up, the genetic characteristics of cardiac rhabdomyoma were summarized on the basis of pathology and genetics examination results. Results The pregnancy outcomes:24 cases were terminated pregnancy, 4 cases were born and 5 cases were lost. The results of ultrasound, pathology and genetic examination were detailed in 8 cases. Pathological examination: the typical characteristics of cardiac rhabdomyoma were found in the 8 cases with cardiac rhabdomyoma. The tumor tissue was composed of irregular and swelling shape of cardiomyocytes, and the cytoplasm was vacuole like, which was characteristic of“spider like cells”through microscopic observation. The geneticdetection results: 7 cases had tuberous sclerosis complex (TSC) gene mutation, TSC gene abnormalities were not detected in 1 case. Among the 7 cases with TSC gene mutations, 6 cases were with TSC2 gene mutation and the other 1 case was with TSC1 gene mutation. The family gene was investigated in the 5 cases, which including 3 cases of TSC gene mutation in mother passed on to the fetus (1 case with family of three generations of genetic) and 2 cases of spontaneous TSC gene mutation in the fetus. Conclusions Prenatal echocardiography combined with genetic detection have important clinical significance, which not only can clear if cardiac rhabdomyomas were associated with TSC, but also can clear the TSC gene mutation source. So as to further guide the perinatal management.

Using a micro-column packed with polyethylenimine aminated glycidyl methacrylatE-grafted-polytetrafluoroethylene fiber made by ourselves as the adsorption material, the adsorption behaviors of Pb and Cd under different conditions were studied by inductively coupled plasma optical emission spectrometry. The conditions for the preconcentration of Pb and Cd such as pH, flow-rate, time and eluent acidity were optimized. The results show that the PTFE-g-GMA-PEI Fiber has excellent adsorption property and high adsorption capacity for Pb2+ and Cd2+. The Enrichment factors for Pb2+ and Cd2+ were 30 and 80, respectively and the detection limits were 3.5 μg/L and 0.15 μg/L, respectively, the relative standard derivations were 1.5% and 0.6%(n=9)respectively. When the single ion concentration was 50 μg/L, the sampling frequency was 9 and 18 times/h, respectively. The method was applied to the simultaneous determination of trace lead and cadmium of several Chinese traditional medicine samples, the standard recovery of samples was 90%-108%.
