OBJECTIVE： To observe the effect of UBIO on the nerve function and activities of K^＋-Na^＋-ATPase and Ca2^＋-Mg2^＋-ATPase activities on the red blood cell （RBC） membrane of patients with acute cerebral infarction. DESIGN： A randomized and controlled study.SETTING： Department of Neurology, Xiangfan Central Hospital.PARTICIPANTS： From January 2000 to December 2001, excluding those above 70 years old, 58 cases of 700 patients with acute cerebral infarction admitted in the Department of Neurology, Xiangfan Central Hospital, were recruited and divided into two groups according to the random number table： UBIO treated group （n=28）, including 17 males and 11 females, aged 40-68 years; and control group （n=30）, including 20 males and 10 females, aged 44-69 years. All the patients agreed to participate in the therapeutic program and detected items. The general informations were comparable without obvious differences between the two groups （P 〉 0.05）.METHODS： ① The patients in both groups received routine treatments, besides, those in the UBIO treated group were given UBIO treatment by using the XL-200 type therapeutic apparatus produced in Shijiazhuang, whose ultraviolet wave was set at 253.7 nm with the energy density of 0.568 J/m^2 per second, UBIO treatment started from the second day after admission, once every other day, with a single course consisting of 5-7 treatments. ② In the UBIO treated group, the venous blood was sampled before and after the first, third and the completion of the treatment course respectively, the venous blood was taken at each corresponding time point in the control group. After centrifugation of the blood at 10 000 rounds per minute, the RBC membrane was separated and then the activities of K^＋-Na^＋-ATPase and Ca2^＋-Mg2^＋-ATPase were detected by means of phosphorus determination.③ The nerve function was scored before and after treatment in both groups with European stroke scale, which included 13 items, the total score was 0-100 points, the higher the score, the better the nerve function. MAIN OUTCOME MEASURES ：①Score of European stroke scale before and after treatment in both groups.② Comparison of the activities of K^＋-Na^＋-ATPase and Ca2^＋-Mg2^＋-ATPase on RBC membrane between the two groups before treatment and after the first, third and the completion of the treatment. RESULTS： All the 58 patients with cerebral infarction were involved in the analysis of results.① The score of European stroke scale had no obvious difference between the two groups [（49.31±11.48）, （50.58±12.63）, P 〉 0.05], and it was obviously higher in the UBIO treated group than in the control group after treatment [84.66±13.75）, （77.05±11.17）, P 〈 0.05].②The activity of K^＋-Na^＋-ATPase on RBC membrane in the UBIO treated group was significantly increased after the first and third treatment as compared with before treatment [（31.56±19.25）, （27.64±15.83）, （17.67±13.83）, P 〈 0.01], it was still higher after the completion of the treatment than before treatment without obvious difference [（20.86±14.53）, P 〉 0.05]. After the first and third treatment, it was obviously higher in the UBIO treated group than in the control group [19.31±11.88）, （17.44±10.42）, P 〈 0.01]. ③ In the UBIO treated group, Ca2^＋-Mg2^＋-ATPase activity on RBC membrane significantly increased after the first treatment and remained higher than the pre-treatment level throughout the treatment [（27.49±14.72）, （17.41±4.82）, P 〈 0.01]. The activity of Ca2^＋-Mg2^＋-ATPase on RBC membrane was markedly higher in the UBIO treated group than in the control group after after the first, third and the completion of treatment respectively [（24.83±12.88）, （17.70±5.69）; （28.08±13.44）, （16.32±5.29）; （17.42±6.04）, P〈 0.05-0.01]. CONCLUSION： The effect of UBIO treatment against acute cerebral infarction may be mediated by the increased K^＋-Na^＋ ATPase and Ca2^＋-Mg2^＋-ATPase activities on RBC membrane, which enhances the RBC transformation ability so as to lower RBC aggregation and correct high blood viscosity.展开更多

Methods: 30 SD rats were made into renal hypertension rats(RHR) by clamping the kidney arteries with silver clip. 42 days later, their bilateral common carotid arteries were blocked repeatedly to cause cerebral ischemia. The Hypertension vascular dementia model was then set up. Then they were randomly divided into VD model group, EA groupand medication group (Dihydroergotoxine, DHET), with 10 cases in each group. The therapeutic course was 28 days. The ability of learning and memory was using an obs erved by water maze, and the function of red blood cell immune was detected after treatment. Results: the latecy of the EA group and medication group was shorter than that of model group (P<0.05, P<0.005), and that of EA group was shorter than medication group (P<0.05, P<0.005). EA and medication could increase the RBCC 3b receptor flower circle rate and reduce the RBCIC flower circle rate significantly(P<0.05, P< 0.01). Conclusion: The results indicated that EA therapy could raise the ability of learning and memory and improve the function of red cell immune in VD rats, while the therapeutic effect of EAis better than DHET.展开更多

Methods Forty-nine Kashin-Beck patients in endemic area aged 13-16 years were divided into two groups and were orally given either selenized yeast or sodium selenite to provide 200 μ g selenium per day for 12 weeks. Erythrocyte selenium level, glutathione peroxidase activity, the rosette formation rates of red blood cells complement receptor typeⅠ(CR1), the immune function of red blood cells, and circulating immune complexes(CIC) were determined. Results After supplementing with selenium for 12 weeks, erythrocyte selenium level, glutathione peroxidase activity, the rosette formation rates of red blood cells CR1 were significantly increased. But the difference in rosette formation rates of IC and CIC content was not significant between before and after Se supplementation. Conclusion The increase of the immune function of the erythrocyte by selenium-supplement may be one of the effective mechanisms for the prevention of Kashin-Beck disease.展开更多
