ABSTRACT
Objective:To elucidate the correlation between urinary 11-dehydro-thromboxane B2 ( 11 dhTxB2 ) and clinical efficacy of aspirin treatment in patients with type 2 diabete and coronary artery disease ( CAD) . Methods:In this prospective cohort study, 169 aged patients with type 2 diabete accom-panying CAD in Peking University First Hospital were enrolled. The level of urinary 11dhTxB2 was detec-ted using enzyme-linked immuno-sorbent assay. Low aspirin response or high on aspirin platelet reactivity (HAPR) was defined as urinary 11dhTxB2>1 500 ng/g. All the included patients were divided into two groups based on the results, HAPR group and No-HAPR group. Results:Baseline urinary 11dhTxB2 of the patients with type 2 diabete accompanying CAD was ( 3 687 ± 3 052 ) ng/g, while the urinary 11dhTxB2 was (1 954 ± 859) ng/g in patients after 100 mg/d aspirin treatment (P<0. 001). Preva-lence of HAPR in patients with type 2 diabete accompanying CAD were 32 . 5%. Within a mean follow-up time of 12 months, the outcomes occurred more frequently in HAPR group than in No-HAPR group ( P<0 . 05 ) . Conclusion:Urinary 11 dhTxB2 can be recognized as an effective indicator in evaluating aspirin clinical efficacy of patients with type 2 diabete accompanying CAD.
ABSTRACT
Objective: To elucidate the correlation between the single nucleotide polymorphism of CKLF-like MARVEL transmembrane member 5 ( CMTM5 ) gene rs723840 and the occurrence of high on aspirin platelet reactivity ( HAPR) . Methods:The present study is a case-control study. A total of 210 hospitalized patients in Peking University First Hospital were enrolled. Aspirin response was assessed by 0. 5 g/L arachidonic acid (AA)-induced platelet aggregation ratio (PR), and ≥3/4 quartile of PR of the population was defined as HAPR. Accordingly all the enrolled 210 coronary artery diseases ( CAD) patients were divided into HAPR group and No-HAPR group. The genotypes were determined by poly-merase chain reaction ( PCR) and sequencing analysis for rs723840 of CMTM5 gene. Results:The geno-type frequencies in rs723840 C>T of CMTM5 gene conformed well to the Hardy-Weinberg equilibrium in both HAPR group and No-HAPR group. Between the two groups, the genotypes frequencies in HAPR and No-HAPR groups were 48 . 4%, 51 . 6%, 0 . 0% and 73 . 7%, 22 . 9%, 0 . 034%, respectively ( P=0. 004). The C, T allele frequencies were significantly different in the two groups (P =0. 031,OR =0 . 501 , 95%CI:0 . 264-0 . 947 ) . Conclusion:Our study finds a significant correlation between CMTM5 gene rs723840 polymorphism and high on aspirin platelet reactivity.
ABSTRACT
Objective To investigate and analyze the mental health status of the students from poor families and non-poor students by comparative study.Methods Conducting the cluster sampling methods,the author investigated 885 medical students with questionnaires.We input data with Epidata 3.0 software and described it with SPSS 11.0 statistical software,which also did the nonparametric rank sum test.Results 92.7％(667/719) students from poor families considered their economic status among the general level or much lower level.There were 41.9％(294/702) students from poor families who thought families' financial difficulties had positive effects on mental health.92.3％(664/719) students from poor families were never afraid that people around knew they were in work-study program.87.5％(629/719) students from poor families were satisfied with their life.Facing psychological problems,there's no difference with dissatisfaction in daily life and recourses for help between students from poor families and non-poor students except psychological consultation center and lovers P＞0.05).Conclusion Compared with non-poor students,the mental health of students from poor families in medical universities is good.The universities are supposed to pay more attention to the mental health of students who are neither poor nor non-poor and few students from poor families who are negatively impacted by their families' financial difficulties.
