【Abstract】 Background There are general individual differences in the clinical efficacy of clopidogrel,which is related to race and affected by genotype.Objective To investigate the correlation of CYP2C19 genetic polymorphism with clopidogrel resistance and prognosis in patients with acute coronary syndrome(ACS) in order to provide a basis for individualized antiplatelet therapy guided by genotyping.Methods From March to December 2012,98 consecutive patients with ACS who were hospitalized at the Department of Cardiology of Aerospace Central Hospital were enrolled.After admission,patients were given clopidogrel at a first dose of 300 mg and then 75 mg/d orally,or administered directly at a regular dose of 75 mg/d.The platelet aggregation rate,platelet inhibition rate and clopidogrel resistance in all ACS patients were evaluated at the time of admission and after a clopidogrel therapy of 3 days.Meanwhile,CYP2C19 gene polymorphisms were determined by Taqman-PCR.Based on CYP2C19 gene test results,according to whether or not the mutant gene A was carried,patients were divided into wild-type group(without mutant gene A in both G681A in fifth exon and G636A in fourth exon,n=34) and mutant group(with mutant gene A in either G681A in fifth exon or G636A in fourth exon,n=64).Follow-up was applied,and major adverse cardiovascular events(MACEs) were recorded.Results The genotypes of CYP2C19*2 and CYP2C19*3 were in accordance with Hardy-Weinberg′s law of equilibrium(P＞0.05),which suggested that the sample included in the study had a good population representativeness.There was no significant difference in baseline platelet aggregation rate between the patients with different CYP2C19*2 genotypes(P＞0.05).In genotype CYP2C19*2 patients,clopidogrel resistance rate was significantly higher in GA patients than in GG patients after 3 days′ clopidogrel therapy(P＜0.05),and clopidogrel resistance rate was significantly higher in AA patients than in GG and GA patients after 3 days′ clopidogrel therapy(P＜0.05).In genotype CYP2C19*2 patients,GA and AA patients had lower platelet inhibition rate than GG patients(P＜0.05).In CYP2C19*2 patients,the platelet aggregation rate in GG and GA genotype patients after clopidogrel therapy of 3 days was less than that at admission(P＜0.05).There was no significant difference in platelet aggregation rate at admission,platelet aggregation rate after 3 days of treatment and platelet inhibition rate in different CYP2C19*3 genotype patients(P＞0.05).In CYP2C19*3 genotype patients,the platelet aggregation rate in GG and GA genotype patients after clopidogrel therapy of 3 days was less than that at admission(P＜0.05).Compared with mutant group,wild-type group had lower clopidogrel resistance(P＜0.05);compared with mutant group,wild-type group had lower lower MACEs(P＜0.05).In genotype CYP2C19*2 patients,GG patients had lower incidence of MACEs than AA patients(P＜0.05),and GA patients had lower incidence of MACEs than AA patients(P＜0.05).There was no significant difference in the incidence of MACEs in genotype CYP2C19*3 patients(P＞0.05).Conclusion CYP2C19 gene polymorphism was associated with antiplatelet effects of clopidogrel in patients with ACS.Patients with CYP2C19 fifth exon mutation had reduced antiplatelet effects and poor prognosis after receiving conventional dose of clopidogrel,but the fourth exon mutation had relatively little effect on the prognosis of the patients.

【Abstract】 Background The prognosis of patients with early and advanced extranodal nasal NK/T-cell lymphoma(ENKTCL) is significantly different.However,ENKTCL is usually misdiagnosed as other diseases in clinical practice.Some previous studies suggested that misdiagnosis of ENKTCL might be related to the nonspecific nature of its initial symptoms.Objective To analyze the relationship between initial symptoms of ENKTCL and time of diagnosis,and explore the factors influencing time of ENKTCL diagnosis in order to provide reference for the early diagnosis of ENKTCL.Methods We retrospectively collected the clinical data of patients who diagnosed with ENKTCL and met the inclusion criteria between 2009 and 2012 in West China Hospital,Sichuan University.The relationship between initial symptoms of the patients and time of diagnosis and the influencing factors of diagnosis time were analyzed.Results One hundred and seventy-seven ENKTCL patients were enrolled finally.The median age was 42（22） years.Males were in the majority(accounting for 71.2%).The common initial symptom was nasal congestion(54.8%),followed by nasal rhinorrhea(21.5%),fever(18.1%) and oropharyngeal pain(14.1%).Relatively rare initial symptoms were tinnitus（1.1%）,decreased vision（1.1%）,hyposmia（1.1%）,etc.No one presented weight loss.The diagnosis time of ENKTCL patients was 4（10） months.When the initial symptom was nasal congestion,it was positively correlated with time of diagnosis（rs=0.228，P=0.004）.When the initial symptom was oropharyngeal pain or fever,it was negatively correlated with time of diagnosis（rs=-0.203 and -0.258,respectively;P=0.007 and 0.001,respectively）.When the initial symptom was epistaxis,rhinalgia,rhinorrhoea,oropharyngeal ulcer,cough,dizziness/headache,night sweats,nodules or masses，it was no linear correlation with time of diagnosis（P＞0.05）.The results of generalized multivariate linear model showed that it had linear regression relation with the time of diagnosis when the initial symptom was nasal congestion 〔β=0.355，95%CI（0.022,0.687），χ2=4.372，P=0.037〕.Conclusion Nasal congestion is the most common initial symptom of ENKTCL patients,and the patients with nasal congestion require a longer time of diagnosis.For patients with long-term nasal congestion,the doctor should seriously consider the risk of ENKTCL,and repeated pathological biopsies should be performed in time if necessary.

【Abstract】 Background Chronic obstructive pulmonary disease(COPD) is a lung disease that includes two main types,chronic bronchitis and emphysema,characterized by chronic incompletely reversible airflow.It is one of the leading causes of pulmonary hypertension.However,its occurrence and development mechanism is not yet fully clear.Objective To explore the TLR-4 expression in distal pulmonary artery smooth muscle cells(PASMCs) of COPD model rats induced by lipopolysaccharide(LPS),so as to provide a theoretical basis for studying the role of TLR-4 signaling pathway in inflammation and immune response to COPD.Methods This study was conducted from December 2015 to March 2016.Twenty-four SPF grade Wistar rats(half males and half females) aging between 6 and 8 weeks were randomly divided into normal group and model group,12 rats in each after feeding adaptively for 1 week.Rats in model group and normal group were respectively administered with 200 μl LPS(1 μg/ml),and 200 μl sodium chloride(0.9%) solutions,via the trachea on the 1st and the 14th day after intervention,and treated by passive inhaling of cigarette smoke in plexiglass cabin for 1 h once daily for 8 weeks.After the intervention,2 rats respectively randomly selected from both groups were sacrificed and the lung tissues were took out for observing the pathological changes via HE staining,and TLR4 expression in PASMCs determined with immunohistochemical(IHC) staining.Six model rats ranomly selected from remaining rats were sacrificed and the distal PASMCs were isolated and cultured.Cultured cells at passages 3-6(logarithmic phase) were used for experiments.The morphology of PASMCs was observed under the optical microscope(the images were magnified 100 times) and α-SM-actin expression in PASMCs stained by immunohistochemistry was observed under the immunofluorescence microscope(the images were magnified 200 times),then they were randomly divided into control group(no intervention),LPS 12 h group(treatment with 10 μl LPS of 1 μg/ml for 12 h),LPS 24 h group(treatment with 10 μl LPS of 1 μg/ml for 24 h),LPS 48 h group(treatment with 10 μl LPS of 1 μg/ml for 48 h) and LPS 72 h group(treatment with 10 μl LPS of 1 μg/ml for 72 h).The TLR-4 protein expression in PASMCs in these 5 groups were measured with Western blotting.Results The pathological changes in lung tissues found in the model group were rupture of alveolar walls,alveolar fusion,formation of bullae,dramatically thickened PASMCs layer in artery,a large number of inflammatory cell infiltration,all these were consistent with COPD typical features.TLR-4 expression in pulmonary artery smooth muscle layer:under the inverted phase contrast microscope,in model group,the TLR-4 expression in pulmonary artery smooth muscle layer was seen to be positive,the pulmonary artery smooth muscle layer was yellow,and it was much deeper than that in the normal group.PASMCs morphology and their α-SM-actin expression:under optical microscope,PASMCs were spindle shaped and presented irregular growth.With the extension of culture time,the number of layers were increased,leading to the formation of "peak valley";under immunofluorescence microscopy,it could be seen that α-SM-actin expression in PASMCs was positive,the cytoplasm had a radial distribution of filaments to the cell poles,parallel to the long axis of the cell,the morphology was clear.TLR-4 expression in PASMCs of LPS 12 h group,LPS 24 h group,LPS 48 h group and LPS 72 h group was higher than that of control group(P<0.05);TLR4 expression in PASMCs of LPS 24 h group,LPS 48 h group and LPS 72 h group was higher than that of LPS 12 h group(P<0.05);TLR4 expression in PASMCs of LPS 48 h group and LPS 72 h group was higher than that of LPS 24 h group(P<0.05).Conclusion TLR-4 expression level increases in distal PASMCs of COPD model rats induced by LPS;it is speculated that LPS could induce the synthesis and secretion of PASMCs through the TLR4 signaling pathway,which aggravated the inflammatory response and pulmonary vascular remodeling.
