目的:调查新疆奎屯高砷地区水砷含量及当地居民健康状况,分析砷对人体肝脏的损害作用,为进一步探讨砷的肝毒性作用机制提供基础资料。方法采用现场流行病学的调查方法在新疆奎屯水砷监测点进行调查,调查对象377例,其中砷暴露组137例,内对照组126例,外对照组114例;分别进行问卷调查、临床检查及样品采集,比较3组肝 B 超检查结果、尿砷含量及肝损伤血清标志物的差异。结果砷暴露组居民尿砷含量为(121.25±18.70)μg/L,高于内对照组的(22.47±19.21)μg/L 和外对照组的(18.52±15.98)μg/L,3组差异有统计学意义(F =65.491,P <0.001)。B 超检查结果显示肝功能正常者325例,异常者52例。砷暴露组和内对照组、外对照组发生肝脏异常分布比较差异有统计学意义(χ2=6.440,P =0.040)。血清肝纤维化指标检测显示砷暴露组的血清透明质酸、层粘连蛋白及Ⅳ型胶原含量与内对照组、外对照组比较差异有统计学意义;暴露组Ⅲ型前胶原肽与内对照组比较差异无统计学意义,而与外对照组比较差异有统计学意义;内对照组与外对照组的层粘连蛋白和Ⅳ型胶原差异有统计学意义。结论新疆奎屯高砷地区居民饮用高砷水与当地居民肝病高发有一定的联系,砷暴露可能是导致肝功能损害尤其是肝纤维化的主要原因之一,应进一步采取针对性措施降低肝损伤发生率,以促进高砷地区各族居民的身体健康。
目的:調查新疆奎屯高砷地區水砷含量及噹地居民健康狀況,分析砷對人體肝髒的損害作用,為進一步探討砷的肝毒性作用機製提供基礎資料。方法採用現場流行病學的調查方法在新疆奎屯水砷鑑測點進行調查,調查對象377例,其中砷暴露組137例,內對照組126例,外對照組114例;分彆進行問捲調查、臨床檢查及樣品採集,比較3組肝 B 超檢查結果、尿砷含量及肝損傷血清標誌物的差異。結果砷暴露組居民尿砷含量為(121.25±18.70)μg/L,高于內對照組的(22.47±19.21)μg/L 和外對照組的(18.52±15.98)μg/L,3組差異有統計學意義(F =65.491,P <0.001)。B 超檢查結果顯示肝功能正常者325例,異常者52例。砷暴露組和內對照組、外對照組髮生肝髒異常分佈比較差異有統計學意義(χ2=6.440,P =0.040)。血清肝纖維化指標檢測顯示砷暴露組的血清透明質痠、層粘連蛋白及Ⅳ型膠原含量與內對照組、外對照組比較差異有統計學意義;暴露組Ⅲ型前膠原肽與內對照組比較差異無統計學意義,而與外對照組比較差異有統計學意義;內對照組與外對照組的層粘連蛋白和Ⅳ型膠原差異有統計學意義。結論新疆奎屯高砷地區居民飲用高砷水與噹地居民肝病高髮有一定的聯繫,砷暴露可能是導緻肝功能損害尤其是肝纖維化的主要原因之一,應進一步採取針對性措施降低肝損傷髮生率,以促進高砷地區各族居民的身體健康。

Objective The survey is to investigate the relationship between local people′s exposure to arsenic in water in Kuitun of Xinjiang and their health status,and to analyze the damaging effect on human hepatic function,which provides the basis for further study of the mechanism of arsenic toxicity.Methods 377 subjects in Kuitun were collected and were surveyed with a questionnaire,clinic examination and sample collection by using the method of field epidemiological investigation,among whom 137 cases are in arsenic exposure group,126 cases in internal control group and 114 cases in external control group.Results The content of urine arsenic in arsenic exposure group is (121.25±18.70)μg/L,which is higher than that in the internal control group (22.47±19.21)μg/L and the external control group (18.52±15.98)μg/L.The difference between 3 groups was statistically significant (F =65.491,P < 0.001).B ultrasound examina-tion showed 325 cases of liver function were normal,52 cases of abnormal liver function.The difference of liver injury rate between arsenic exposed group and the control group was significant (χ2 = 6.440,P =0.040).Detection of serum liver fibrosis indexes showed significant differences in serum hyaluronic acid, laminin and type Ⅳ collagen content between exposure group and the control group.It showed no signifi-cant difference in type Ⅲ precollagen between the exposure group and internal control group.There was significant difference in laminin and type Ⅳ collagen between internal control group and external control group.Conclusion There is a link between drinking water with high arsenic and local residents liver disea-ses in Kuitun of Xinjiang.Arsenic exposure may cause liver damage,particularly liver fibrosis.Therefore, we should take further measures to reduce the incidence of liver injury,and to promote the health of all residents in high arsenic area.
