Decreased gastric body mucosa obestatin expression in abdominal obesity patients with normal body mass index / 生物医学与环境科学（英文）

The aim of the study was to investigate whether the expression of obestatin in gastric body mucosa in abdominal obesity patients with normal body mass index (BMI) is different compared with healthy controls. Twenty abdominal obesity patients with normal BMI and twenty healthy controls were included in the study. The number of obestatin-positive cells in gastric body mucosa was significantly lower in abdominal obesity patients with normal BMI than that in healthy subjects. There was a positive correlation between the numbers of obestatin-positive cells in the gastric body mucosa and plasma obestatin levels in abdominal obesity subjects and control group.

Observation on therapeutic effect of eye-needling combined with medication for treatment of ophthalmoplegia / 中国针灸

<p><b>OBJECTIVE</b>To observe the therapeutic effect of eye-needling combined with medication for treatment of ophthalmoplegia and explore the possible mechanism.</p><p><b>METHODS</b>One hundred and twenty cases were randomly divided into a treatment group and a control group. According to etiological factors, the control group were treated with medication and the treatment group with the medication plus eye-acupuncture at main point ocular muscles. Changes of the rima oculi, the range of ocular movement and the dialopia angle after treatment were recorded and statistically analyzed in the two groups.</p><p><b>RESULTS</b>The total effective rate was 93.4% and the cured rate was 54.1% in the treatment group, and 74.6% and 18.6% in the control group, with significant difference between the two groups (P < 0. 01).</p><p><b>CONCLUSION</b>Eye-needling combined with medication has an obvious therapeutic effect which is better than simple medication for ophthalmoplegia.</p>

Oxidative damage to DNA and its relationship with diabetic complications / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To detect the oxidative DNA damage in diabetic patients and to investigate the relationship of oxidative DNA damage with diabetes and diabetic nephropathy.</p><p><b>METHODS</b>Single cell gel electrophoresis (SCGE) was used to detect the DNA strand breaks in peripheral blood lymphocytes, and oxidative DNA damage product and serum 8-OHdG were determined by a competitive ELISA in 47 cases, including 25 patients without diabetic complications, 22 patients with diabetic nephropathy and 25 normal control subjects.</p><p><b>RESULTS</b>Diabetic patients showed greater oxidative damage to DNA. The percentage of comet cells and the length of DNA migration (comet tail length) of peripheral blood lymphocytes were significantly increased in patients with diabetes, and significantly higher in patients with diabetic nephropathy than in diabetic patients without vascular complications (P < 0.05). There was a significant increase in serum 8-OHdG in diabetic patients compared with normal subjects (P < 0.05). Moreover, serum 8-OHdG was much higher in patients with diabetic nephropathy than in diabetic patients without vascular complications (P < 0.05).</p><p><b>CONCLUSION</b>There is severe oxidative DNA damage in diabetic patients. Enhanced oxidative stress may be associated with diabetes, especially in patients with diabetic nephropathy.</p>
