The correlation of allergic rhinitis and trace elements in Ningxia region / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the correlation of allergic rhinitis and trace elements and to provide a reference for clinical diagnosis, treatment and prevention of allergic rhinitis.</p><p><b>METHODS</b>One hundred and six patients were diagnosed as allergic rhinitis in General Hospital of Ningxia Medical University between January and December in 2010, including 48 cases of perennial allergic rhinitis and 58 cases of seasonal allergic rhinitis. In the same time, one hundred and three healthy volunteers were selected as control. Intravenous blood 3-5 ml were obtained from all subjects both in experimental group and in control group. The content of Ca, Ni, Fe, Mg, Zn, Sr, Mn, Cu, Se in serum and hair was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). The t-test (SPSS 16.0) was used to compare the results of trace elements in serum between allergic rhinitis and control group.</p><p><b>RESULTS</b>The testing results of trace elements in AR patients serum and normal controls serum were as follows: Cu, Ni (1 002.18 ± 104.62) µg/L, (21.58 ± 5.54) mg/L were super than control group, (832.78 ± 50.45) µg/L, (17.04 ± 4.93) mg/L (t value was 15.545, 5.154, both P < 0.05). But the content of Zn, Se (793.48 ± 46.88) µg/L, (84.25 ± 12.77) µg/L lower than control group (908.53 ± 31.26) µg/L, (98.35 ± 15.21) µg/L (t value was -24.175 and -7.797, both P < 0.05) . The testing results of trace elements in AR patients hair and normal controls hair were as follows: Cu, Ni (42.43 ± 5.03) µg/g, (31.72 ± 5.49) µg/g were super than control group, (23.00 ± 4.45) µg/g, (8.94 ± 7.53) µg/g (t value was -8.633 and 4.236, both P < 0.05). But the content of Zn, Se (92.16 ± 4.54) µg/g , (0.28 ± 0.04) µg/g lower than control group (189.09 ± 8.45) µg/g, (0.39 ± 0.06) µg/g (t value was -28.71 and -8.633, both P < 0.05).</p><p><b>CONCLUSIONS</b>The content of Zn, Se in AR patients serum are lower than that in control group. But the content of Cu, Ni in AR patients serum are super than that in control group. There are no significant difference of trace elements in the serum between pennial allergic rhinitis and seasonal allergic rhinitis.</p>

Clinical Correlation between Plasm Homocysteine Levels and Cerebral Infarction / 昆明医科大学学报

Objective To investigate the relationship between the plasma homocysteine (Hcy) and cerebral infarction.Methods 84 patients with cerebral infarction in our department were selected as study group and 56 cases from medical examination center were selected as control group. The fasting plasma homocysteine (Hcy) was determined in both groups . Result The level of Hcy in cerebral infarction group was significantly higher than the control group, there was a significant difference ( <0.01) .Conclusion High homocysteine levels is an important independent risk factor of cerebral infarction.
