贵州省地方性氟中毒地区人群GSTP1基因Ile105Val位点多态性分析

Objective To investigate plasma glutathione S-transferase(GSTs) activity and GSTP1 gene Ile105Val polymorphism in Bijie City, Guizhou Province, a coal-burning fluorosis endemic area. Methods One hundred and sixty villagers from Yachi Twon using non-improved cooking stoves were selected as the non-intervened group in Bijie City, Guizhou Province where coal-burning fluorosis was prevailing; 153 villagers as the intervented group were chosen from Changchun Twon, where cooking stoves were improved; 151 villagers were served as the control group from Baiyunshan Twon, Changshun County without endemic fluorosis. The activity of GSTs was tested by colorimetric analysis with spectrophotometer. The genotype of the GSTP1 gene Ile105Val polymorphism, presenting as either homozygous wild-type (AA), or heterozygous mutation type (AG), or homozygous mutation type (GG), was detected through the PCR-RFLP procedure. Results The activity of GSTs in plasma of non-intervened group [(12.44±4.97) kU/L]was significantly lower than that of intervened group (P < 0.05), and that of intervened group[(20.78±6.20)kU/L]was significantly lower than that of control group[(24.30±6.27)kU/L, P< 0.05]. The difference of the enzyme activity of three groups were statistically significant (F = 51.71, P < 0.05), but this enzyme activity did not vary significantly in each sex of each grnup(P > 0.05). Compared intervened group [AA:67.3%(103/153), AG:29.4%(45/153),GG:3.3%(5/153)]and non-intervened group[AA:66.9%(107/160), AG:30%(48/160), GG:3.1%(5/160)]with control group[AA:74.8%(113/151), AG:25.2%(38/151), GG:0 (0/151)], the Ile105Val polymorphism site of GSTP1 gene had significant difference(χ2= 6.04,6.07, both P< 0.05), but not significant between intervened and non-intervened groups(χ2 = 0.02, P>0.05). Conclusions Fluorosis can decrease the activity of GSTs and introduce the GSTP1 gene Ile105Val polymorphism, intervention with the fluorine intake will improve the effect of fluoride on the body.

Pavlik吊带治疗6个月内婴儿髋关节发育不良

目的探讨Pavlik吊带治疗6个月内婴儿髋关节发育不良的方法和疗效以及高频超声在诊断治疗中的价值。方法回顾性总结我院2004年1月至2012年1月收治的102例(124髋)6个月内发育性髋关节异常的婴儿,其中男性14例,女性88例,单侧80例,双侧22例,年龄3~24周。据Graf超声波髋关节分型,20髋为Ⅱa(-)型,50髋为Ⅱb型,34髋为Ⅱc型,18髋为Ⅲ型,2髋为Ⅳ型。常规新生儿体检均发现有双侧臀纹不对称,或伴有髋关节屈曲外展受限,经Garf静态超声技术确认。均采用Pavlik吊带治疗,平均间隔2~3周超声监测髋关节发育变化。吊带治疗时间4~20周,随访时间15~30个月,平均24个月。结果 92例(112髋)经Pavlik吊带治疗后,复查超声和X线片指标恢复正常,确认治愈。4例(5髋)治疗过程中超声指标改善明显,58°α角60°,年龄超过8个月后,改用髋外展矫形器固定,4周后X线片指标恢复正常。6例(7髋)年龄超过6个月,指标未恢复正常,且伴有内收肌紧张,予以内收长肌松解后石膏固定。在此6例患儿中,3例(3髋)随访至18个月,髋臼指数大于25°,Sheton氏线不连续,行Salter骨盆截骨术。所有患儿均无股骨头无菌性坏死等并发症。结论 Pavlik吊带对于GrafⅡ型患儿治愈率高,而对于GrafⅢ、Ⅳ型患儿,Pavlik吊带治愈率降低,部分患儿需后续进一步治疗。超声检查可动态观察Pavlik吊带治疗效果。早期超声检查为及时应用Pavlik吊带治疗提供了可能,对减轻患儿晚期畸形和并发症有重要意义。
