Serum levels of nerve injury markers, nerve cytokines and inflammatory cytokines were detected before as well as 1 d and 7 d after thrombolytic therapy.Results:1 d and 7 d after thrombolysis, serum nerve injury markers NSE, S100B, MDA and 8-OHdG as well as inflammatory cytokines IL-1β, IL-18, TNF-α and sVCAM-1 levels of both groups of patients were significantly lower than those before treatment while nerve cytokines BDNF, NGF and VEGF levels were significantly higher than those before treatment, and serum nerve injury markers NSE, S100B, MDA and 8-OHdG as well as inflammatory cytokines IL-1β, IL-18, TNF-α and sVCAM-1 levels of rt-Pa group were significantly lower than those of UK group while nerve cytokines BDNF, NGF and VEGF levels were significantly higher than those of UK group. Conclusion: Alteplase thrombolysis for acute cerebral infarction can reduce nerve injury, improve neurotrophic state, and inhibit inflammatory response.展开更多

Methods Acupuncture was applied at the eight points surrounding the umbilicus: bilateral Tianshu (天枢ST 25), Huaroumen (滑肉门ST 24) and Wailing (外陵ST 26), Yinjiao (阴交CV 7) and Shuifen (水分CV 9), and also Guanyuan (关元CV 4) and Zusanli (足三里ST 36), and the ear embedding method was used in combination in 50 cases of simple obesity. The changes in FBG, INS, ISI, TC, TG, LDL-C and HDL-C after the treatment were observed. The changes in waistline (WL) and hip circumference (HC), their ratio (WL/HC), body weight (BW) and body mass index (BMI) after the treatment were also observed, and the therapeutic effects were compared between the patients with obesity in Grade Ⅰ and Grade Ⅱ. The aforementioned values were compared with those in the control group comprised of 30 normal subjects. Results Hyperinsulinemia (HI) appeared in the patients with simple obesity, and the value of ISI was obviously decreased, compared with that in normal subjects ( P<0.01 ). After the treatment, the values of WL, HC, WL/HC, BW and BMI were all obviously decreases ( P<0.05 ), and those of FBG, INS, TC, TG and LDL-C also reduced ( P<0.01 ), but those of ISI and HDL-C obviously increased ( P<0.05 ). Conclusion Acupuncture can not only efficiently improve the parameters in body fat in the patients with simple obesity, but also regulate their abnormal lipid metabolism and improve the situation of insulin resistance.展开更多
