广东省梅县重点人群碘营养状况调查分析

Objective To estimate the present salt iodine content and iodine nutrition need of high risk population of iodine deficiency disorder in Meixian County. Methods Each primary school was selected from urban and rural areas(Xiyang Town, 20 kilometers away from Meixian County), the goiter rate of 8 to 10 year-old students was examined and urinary iodine and household salt iodine was sampled. Twenty to 40 year-old women of childbearing age nearby schools around the urban and villages around Xiyang Town were selected to collect their urine and salt samples. At urban hospitals and rural health centers, 0 to 2 year-old infant urine samples were collected, Thyroid gland was palpated and urinary iodine was determined by iodine in urine by As3+-Ce4+catalytic spectrophotometry, salt iodine was determined by direct titration. Results The goiter rates of 8 to 10 year-old students were 1.5 % (3/200), 1.0% (1/100) for the urban area and 2.0% (2/100) for rural area. Median of urinary iodine in 8 to 10 year-old students, infants, women of childbearing age averaged at 237.1 μg/L and 280.1, 234.7,187.6 μg/L respectively, with each being 287.4,245.0,205.5 μg/L in urban area and 278.9,228.5,176.4 μg/L in rural area. Women of childbearing age had a higher percentage of urinary iodine < 50.0 μg/L than students,students had a higher percentage than infants, each being 7.5%(15/200), 4.5%(9/200), 4.0%(4/100). The ration of urinary iodine > 300.0 μg/L was more in infants than in students, that in students was more than that in women of childbearing age, each being 33.0% (33/100), 30.0% (60/200),22.5% (45/200). The median of salt iodine was 27.2 mg/kg. The coverage of iodized salt was 100.0%(400/400). Ninty-seven percent(194/200) and 96.0% (192/200) of qualified iodized salt were consumed in urban area and in rural area. Conclusions The amount of iodine added to salt meets the requirement in the 3 kinds population risk of iodine deficiency disorder. But a higher iodine status has been found out in students and infants. It is reasonable to decrease the present salt iodine content.     

阴离子间隙及预计代偿值在糖尿病酮症酸中毒中应用的研究

为探讨糖尿病酮症酸中毒（ＤＫＡ）酸碱失衡,我们于１９９５年１１月～１９９７年１１月收治２１例ＤＫＡ患者,测定其血气、电解质值,运用阴离子间隙（ＡＧ）、预计代偿值２种方法进行分析,并与综合判断方法进行比较,现报道如下。１　资料和方法１．１　一般资料　２１例ＤＫＡ患者,男１０例,女１１例;年龄１３～６９岁,平均３８．５岁。急查血糖１３．３～２７．１ｍｍｏｌ／Ｌ,平均２０．１ｍｍｏｌ／Ｌ;尿糖、尿酮体＋＋～＋＋＋;动脉血气：ｐＨ６．８５～７．３２,平均７－１１,碱剩余（ＢＥ）－６．９～－２８．０,平均…     

马齿苋的研究概况及开发利用

<正> 马齿苋又名马舌菜或马齿菜,为马齿苋科植物马齿苋Protulaca deracea L.的全草。《本草纲目》谓其:“散血、消肿、利肠滑胎、解毒通淋、治产后虚汗”。具有生命力强、易采集、价格低、药食两用等特点。近年,其临床应用和开发日趋广     

抗-N致ABO血型正反不符

目的探讨献血员ABO血型复查时出现正反不符的原因。方法常规微柱凝胶卡法对献血员进行ABO、Rh D血型复查,发现1例献血员血样出现ABO正反不符现象,排除自身凝集后进行不规则抗体筛查、抗体鉴定试验。结果经抗体鉴定与MN血型鉴定试验确定该献血员血样中检出Ig M类抗-N抗体。结论医院输血科在进行献血员ABO血型复查时能够及时发现由于盐水反应性冷抗体所引起的ABO正反定型不符从而发现ABO以外不规则抗体,将减少不必要的疑难交叉配血。     

新生儿血型鉴定困难的探讨

目的探讨分析疑似B亚型的ABO溶血新生儿的血型。方法对患儿进行新生儿溶血病检测,对患儿ABO血型进行血清学鉴定和基因检测。结果 ABO血型血清学鉴定疑似B3,基因检测结果为B101/O01基因型。结论新生儿ABO血型鉴定困难时可以通过基因检测技术来进一步确认,待年龄到一周岁以后复查血型来验证为佳。     

合同护士权益保障与护理质量关系探讨
