一起农户自制年糕出现变色事件的调查处理报告

2005年春节前我所陆续接到了本市部分农户反映自制年糕出现异常变色的情况报告，经对调查情况和相关样品检测结策进行综合分析。我所最终认定引起年糕变色事件的主要原因是农户浸泡年糕所有的明矾（硫酸铝铵）中含有大量铁所致。     

铁块煅毛发饮治疗鼻衄

取长约10cm人毛发15根，除去杂质，用碱水洗去油垢，清水漂净，晾干备用；取一可放于碗中大小的铁块，以略生锈为宜，除去杂质，清水漂洗3～5次，晾干后置于火上，烧至通红，取出放于碗中。将上述备好的毛发撤于铁块上，毛发旋即炭化，兑入开水，使水面淹没铁块，加盖浸泡10min，取汁去沉淀后，加红糖适量搅拌即可。笔者以此饮治疗各种鼻衄数十例，均1～2剂而愈，其中以青春期鼻衄疗效最佳。毛发煅炭可收敛止血，化瘀生新，止血而不留瘀，明显缩短凝血时间；铁块尤其是煅铁块能促进红细胞新生，补血生血及平抑相火妄动。

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.

充血性心力衰竭与血清铁镁锌关系的探讨(附86例报告)

本文采用火焰原子吸收光谱法对86例充血性心力衰竭患者和40例健康者进行了血清微量元素铁镁锌的检测,并进行了对比分析,随访病期动态改变。结果表明:充血性心衰各组血清铁镁锌水平与对照组存在显著差异(P<0.01),且随着心衰的加重血清铁镁锌下降明显(P<0.01),随着心功能的改善,血清铁镁锌渐回升,提示血清铁镁锌的含量与充血性心衰的发生发展密切相关,能反应心衰的程度并可做为判断预后的指标。适当补充铁镁锌有助于心功能的改善。
