Objective To investigate the effect of 60Co γ-ray irradiation on the quality of theleukocyte-filtrated red blood cells suspension.Methods Thirty bags of leukocyte-filtrated red blood cells were randomly divided into irradiation group(n =15) which was given 60Co γ-ray irradiation and control group(n =15) which was not given 60Co γ-ray irradiation.The content of extracellular K +,Na +,free hemoglobin (FHb),adenosine triphosphate (ATP) and 2,3-diphosphoglyceric acid (2,3-DPG) and pH value of the leukocyte-filtrated red blood cells were detected in the two groups.Results The content of K+,Na+,FHb,ATP,2,3-DPG and pH value in irradiation group was (5.20 ± 0.37) mmol · L-1,(140.22 ± 0.05) mmol · L-1,(0.44 ±0.04) mg· L-1,(5.18 ± 0.13)μmol· L-1,(3.34±0.30) mmol· L-1 and 6.85±0.02;the content of K +,Na +,FHb,ATP,2,3-DPG and pH value in the control group was(5.00 ± 0.40)mmol · L-1,(140.47 ± 0.83)mmol · L-1,(0.42 ± 0.08) mg · L-1,(5.22 ± 0.06) μmol · L-1,(3.56 ± 0.52) mmol · L-1 and 6.84 ± 0.05;there was no statistic difference in the content of K +,Na +,FHb,ATP,2,3-DPG,and pH value between the two groups(t =1.93,-1.67,-1.64,-2.02,1.77,1.82;P ＞ 0.05).Conclusion 6o Co γ-ray irradiation of the leukocyte-filtrated red blood cells can not effect the activity and function of red blood cells.

Objective To evaluate clinical effect of Compound Fanshiliu Recipe(CFR) for the treatment of over-weighted type 2 diabetes mellitus(T2DM). Methods One hundred and twenty over-weighted T2DM patients were randomized into treatment group and control group, 60 cases in each group. Both groups were given oral use of Metformin Hydrochloride Enteric-Coated Tablets, and additionally the treatment group was treated with CFR orally. The treatment of both groups lasted for 12 continuous weeks. Before and after treatment, we detected the waist circumference (WC), body mass index (BMI), and the levels of fasting blood glucose(FBG), postprandial 2-hour blood glucose(P2hBG), glycosylated hemoglobin(HbA1c), total cholesterol(TC), triglyceride (TG), and free fatty acid (FFA). The therapeutic effect of the two groups was also evaluated after treatment. Results (1) The total effective rate for traditional Chinese medical symptoms was 95.00% in the treatment group, and was 70.00%in the control group, the difference being significant(P<0.01).(2) After treatment, WC and BMI were decreased in the treatment group(P<0.01 compared with those before treatment), but had no significant decrease in the control group(P>0.05). The decrease of WC and BMI of the treatment group was superior to that of the control group(P<0.05).(3) After treatment, levels of FBG, P2hBG, HbA1c, TC, TG, and FFA of both groups were significantly improved (P<0.05), and the improvement of the treatment group was superior to that of the control group(P<0.05).(4) Three patients of the treatment group suffered from slight gastric discomfort, and the discomfort was relieved without any special treatment. Other patients of the two groups had no adverse reaction. Conclusion Treatment of CFR combined with Metformin has been proved to be an effective and safe approach to decrease blood glucose and blood lipid levels, promote weight loss, and ameliorate traditional Chinese medical symptoms.
