全自动毛细管电泳技术在柳州市新生儿地中海贫血筛查的应用及价值

目的探究全自动毛细管电泳技术在柳州市新生儿地中海贫血筛查的应用及意义。方法选择柳州市10971名新生儿为研究对象,采取全自动毛细管电泳技术对其足跟血进行检测,收集并记录数据,来探究全自动毛细管电泳技术在柳州市新生儿地中海贫血筛查的临床意义。结果全自动毛细管电泳技术测定10971名新生儿足跟血标本。HBbarts的阳性（α地中海贫血）例数为1129例,所占比例为10．29％,而其中含量范围0—10％（静止型＋轻型）为1108例,占阳性比例的98．14％（1108／1129）;HBA区〈9％（可疑B地中海贫血）的有1064名,所占比例为9．70％。结论全自动毛细管电泳技术具有操作简单、结果明了、准确率高等优点,能较准确的进行地中海贫血的筛查,具有较高的临床价值,值得在基层推广。

Parkin基因启动子区-258T/G多态性与广西地区散发性帕金森病的相关性分析

Objective To investigate the association between the-258T/G polymorphism.in the pro-moter of parkin gene and the risk for sporadic parkinson's disease (SPD) in Guangxi Province, and in relationto the age of onset, of PD patients. Methods PCR-RFLP and sequence analysis were used to determine thegenotype of-258T/G polymorphism between all patients and healthy controls. Results The G allele was morecommon in patients than controls (55.20%:43.33% ,x2=6.898, P<0.05, OR=1.61, 95% CI: 1.13 ～2.30). The frequency of GG genotype was higher in patients than in controls (28.00 %: 18.33%, x2=7.159, P<0.05, OR=2.75, 95% CI : 1.31 ～ 5.77). The frequency of TG + GG genotype was higher in pa-tients than in controls (82.40%:68.33%, x2=6.551, P<0.05, OR=2.17.95%CI: 1.20 ～3.93). Afterbeing stratified by onset age, the frequencies of the G allele and GG genotype were significantly higher in pa-tients with onset age over 50 years than those in controls respectively. On the other hand, the frequency was notsignificantly different between the younger onset PD patients and the controls. Conclusion The parkin promot-er-258T/G polymorphism might be a risk factor for PD in Guangxi Province, and the G allele was increasedwith increasing age.
