格林—巴利综合症血清唾液酸、磷脂、胆固醇的测定及其临床意义

本文应用硫代巴比妥酸(TBA)法对34例格林—巴利综合征(GBS)患者51次血清唾液酸(SA)测定。结果显示:患者血清SA含量显著高于50例对照组,血清SA阳性率亦显著高于对照组;GBS患者四肢肌力与血清SA呈负相关;以重型GBS血清SA含量显著高于轻型,病程初期高于患病后期;血清磷脂含量GBS明显高于对照组,而血清胆固醇两组变化无显著性意义。本文提示GBS血清SA含量变化能够反映周围神经损伤的程度。     

广西毛南族农村妇女铁营养状况调查

对450名广西环江县毛南族农村育龄妇女进行血清铁蛋白(SF)、红细胞游离原卟啉(FEP)及血红蛋白(Hb)3项铁指标测定.结果发现:铁缺乏症患病率为27.8%(其中ID4.2%,IDE 7.8%,IDA 15.8%).随着孕次或产次的增加,血红蛋白水平逐渐下降,铁缺乏症患病率逐渐增高.有妊娠或分娩史的妇女与未孕或未生育的妇女血红蛋白水平与铁缺乏症患病率比较均有显著性差异(P<0.05).     

5种拟钉螺酯酶同工酶酶谱的比较研究

采用聚丙烯酰胺凝胶垂直平板电泳技术，对湖北和四川两省５种拟钉螺的酯酶同工酶酶谱进行比较研究，并以湖北钉螺作对照，５种拟钉螺酯酶同工酶共分离出８条酶带，酶谱可分成３区，即ＥＳＴ－１、ＥＳＴ－２、ＥＳＴ－３，其基本特征与钉螺显著不同，很容易通过酶谱将拟钉螺与钉螺区分开，同时，５种拟钉螺的酯酶同工酶酶谱之间均存在一定的差异，说明拟钉螺种间酯酶同工酶存在多态，而种间差异程度似与地域隔离的远近有关。结果提示拟钉螺酯酶同工酶的酶谱特征既有助于拟钉螺属的鉴定，又有助于拟钉螺近缘种的区分，从而对拟钉螺的分类有较大的参考价值。     

复发性口腔溃疡患者血Cu,Fe,Zn含量分析

目的：探讨微量元素在复发性口腔溃疡发病中的作用。方法：检测了44例复发性口腔溃疡患者血清微量元素Cu,Fe,Zn含量，并与正常健康人对照，统计结果用t检验。结果：复发性口腔溃疡患者血清Zn含量明显低于对照组，而Fe含量高于对照组。结论：提示缺Zn是诱发复发性口腔溃疡的因素之一。     

Serum intact parathyroid hormone levels in elderly Chinese females with hip fracture

Summary Serum intact parathyroid hormone (PTH), 25 hydroxyvitamin D(25OHD), 1,25 dihydroxyvitamin D (1,25(OH)₂D), albumin, and ionized calcium were measured in 61 Chinese female patients with hip fracture and 61 control subjects. Hip fracture patients had low albumin, ionized calcium, and 250HD levels. Serum PTH and 1,25 (OH)₂D values were not different between the two groups. We conclude that although 250HD level in hip fracture patients is low, there is no evidence of secondary hyperparathyroidism, suggesting that the low 250HD levels may be a secondary phenomenon in response to the fracture.     

Close correlation between high-density lipoprotein and triglycerides in normotriglyceridaemia.

The relationship between high-density-lipoprotein (HDL) particle size subclasses and the levels of the major lipoprotein lipids was studied in 74 men consecutively referred to the lipid clinic. HDL (density 1.070-1.21 kg l-1) was separated by polyacrylamide gradient gel electrophoresis (GGE) into five size-defined subclasses, in order of decreasing size as follows: HDL2b, HDL2a, HDL3a, HDL3b and HDL3c. Cholesterol and triglyceride concentrations in very-low-density (VLDL), low-density (LDL) and high-density (HDL) lipoproteins were determined. The level of VLDL triglycerides was negatively correlated with HDL2b (r = -0.66, P less than 0.0001), and positively correlated with HDL3b concentrations (r = 0.65, P less than 0.0001). Both correlations were restricted to subjects with VLDL triglyceride concentrations of less than 1.80 mmol l-1, i.e. those with normotriglyceridaemia. Patients with a history of myocardial infarction and/or angina pectoris (n = 18) had significantly lower HDL2b levels than subjects with asymptomatic hyperlipidaemia (n = 50), i.e. 0.16 vs. 0.22 mg protein ml-1 (P less than 0.05), despite essentially similar cholesterol and triglyceride levels in the VLDL, LDL and HDL fractions, including HDL2 and HDL3 cholesterol.
