铁调节蛋白2基因多态性与阿尔茨海默病及血管性痴呆的相关分析

Objective To evaluate the association of 2616c/T polymorphism in iron regulatory protein 2(IRP2)gene with Alzheimer disease(AD)and Vascular dementia(VD).Methods In this study,281 patients with AD,60 with VD,and 285 normal aged were recruited.The 2616C/T polymorphism in IRP2 gene was analyzed by using polymerase chain reaction-restriction fragment length polymorphism.And the cognitive function was assessed with the Mini-Mental State Examination(MMSE).Results (1)No significant difieFences were demonstrated in IRP2 genotype or allele frequencies between AD patients and controls(χ2=2.46,P=0.292;χ2=2.17,P=0.141 respectively).However,when AD patients were stratified by disease severity.the frequency of T allele carriers in the moderate to severe AD patients was 78.0%,significantly higher than that in controls(69.8%;χ2=4.106,P＜0.05).Logistic regression analysis demonstrated that the age-,sex-and ApoE-adiusted OR of modcrate to severe AD patient with T allele was 1.62(95% CI=1.03-2.54).The frequency of T allele carriers or T allele in VD patients was higher than that of controls,but the difference was not statistically significant(P＞0.05).(2)The frequency of tit genotype or T allele in the moderate to severe AD patients was significantly higher than that in mild AD patients(25.8%vs.12.5%,χ2=5.477,P＜0.05;51.9%vs.40.3%,χ2=5.803,P＜0.05 respectively).(3)MMSE scores of the AD patients with TT genotype was significantly lower than ones with CC or CT genotype(P=0.028;P=0.014 respectively).Conclusion The 2616C/T polymorphism in the IRP2 gene is possibly associated with moderate to severe AD.but not associated with VD.And the TT genotype may be a risk factor for cognitive impairment of patients with AD in Chinese Han.

α2-巨球蛋白基因I1000V多态性与散发阿尔茨海默氏病的关联研究

目的近年来有研究发现α2-巨球蛋白基因(α2-macroglobulin，A2M)Ile1000Val多态与阿尔茨海默氏病(Alzheimer’s disease，AD)发病有关联，但也有相悖的研究结果报道。因此．我们利用较大的样本，观察了A2M基因Ile1000Val多态在广州及成都地区汉族老年人中的分布，并探讨其与散发AD的相关性。方法以广州地区257例散发AD患者和242名正常老年人、成都地区112例散发AD患者和113名正常老年人为对象进行病例一对照研究。用聚合酶链反应一限制性片段长度多态性方法分析A2M基因11000V多态性和载脂蛋白E基因(apolipoprotelnE，apoE)多态性。结果(1)在两地合并样本中，AD患者与对照组中等位基因A2M-1000V的频率分别为7．7％与8．7％，广州与成都地区AD患者与对照组中A2M基因I1000V多态的分布差异无统计学意义。(2)散发AD无论按是否伴有apoE—ε4或按发病年龄分成不同亚组后，A2M基因I1000V多态的分布在病例组与对照组之间差异无统计学意义。结论广州与成都汉族人群中A2M基因I1000V多态与散发AD不具有关联。     

新生儿窒息肌酸激酶改变与临床分析

目的观察新生儿窒息与心肌酶谱中肌酸激酶改变之间的关系.方法使用全自动生化分析仪,对108例窒息新生儿及50例非窒息新生儿行血生化动态检测.结果窒息新生儿心肌酶谱明显高于非窒息新生儿,尤以肌酸激酶(CK)最为突出,窒息越重,CK值明显增高,此外3～5天后复查,随着临床症状的好转,CK值也逐渐下降.结论早期动态行血清CK值测定,可以及时诊断和治疗心肌损害;对判断新生儿窒息程度及判断预后提供早期依据,可做为协助判断新生儿是否存在窒息及窒息程度的有效指标.     

认知行为治疗联合药物治疗强迫症疗效的meta分析

目的:通过对随机对照试验的数据进行meta分析,比较药物联合认知行为治疗(CBT)与单纯药物或CBT治疗对强迫症的疗效,为临床实践提供选择依据.方法:检索PubMed、Embase和Central数据库,收集比较药物联合CBT与单纯药物或CBT治疗强迫症疗效的随机对照试验,选取联合治疗组与单纯治疗组的耶鲁-布朗强迫量表测量数据并采用均差作为效应量,应用RevMan5软件进行meta分析.结果:共纳入7项符合标准的研究,合计样本量468人.排除可能引起异质性的1组数据后,3组数据比较了药物联合CBT与单纯药物治疗的疗效且无异质性(Q=0.48,P＞0.1),结果显示联合治疗组对强迫症状的改善优于单纯药物组(MD =6.46,Z=5.03,P≤0.05);7组数据比较了药物治疗联合CBT与单纯CBT的疗效且无异质性(Q=9.08,P＞0.1),结果显示联合治疗组与单纯CBT组对强迫症状的改善没有差别(MD =0.87,Z=1.22,P＞0.05).结论:鉴于目前结果,推测对于强迫症状的改善,药物治疗联合CBT优于单纯药物治疗而与单纯CBT相当,但仍需进一步研究证实.     

恩替卡韦联合康艾注射液治疗HBV相关性中晚期肝癌患者的肝功能、凝血、血常规和HBV-DNA水平变化的临床观察

目的观察恩替卡韦联合康艾注射液治疗HBV相关性中晚期肝癌患者的肝功能、凝血、血常规和HBV-DNA水平变化。方法将60例HBV相关性中晚期肝癌患者在化疗和放疗的基础上,随机分为两组。恩替卡韦联合康艾注射液为观察组(30例)和单用康艾注射液为对照组(30例)进行治疗,观察疗程20周。分析未治疗和治疗后两组患者的肝功能(PA、TBA、ALB、ALT、TBIL)、凝血指标(PT、PTA、APTT、TT、FIB)、血常规(WBC、PLT)和HBV-DNA水平的变化。结果恩替卡韦联合康艾注射液应用观察组的患者,在肝功能(PA、TBA、ALB、ALT、TBIL)、凝血指标(PT、PTA、APTT、TT、FIB)、血常规(WBC、PLT)和HBV-DNA的水平改善方面明显优于对照组(P<0.05)。结论恩替卡韦联合康艾注射液治疗治疗HBV相关性中晚期肝癌治疗具有较好的临床效果,能够有效地改善肝癌患者的肝功能、凝血功能、血常规指标和HBV-DNA水平。
