Methods: A total of 150 patients with diabetic peripheral neuropathy who had received treatment in the Hospital between January 2017 and July 2018 were selected. The patients were randomly divided into two groups, with 75 cases in each group. The control group was treated with Xueshuangtong Injection and Kallikrein, and the observation group was treated with lipoic acid plus medicines given to the control group. The nerve conduction velocity, blood pressure and blood glucose, serum lipids, and serum inflammatory factors were compared between the two groups. Results: The CPT values of the median nerve-ulnar nerves, bilateral superficial peroneal nerves and deep peroneal nerves in the observation group at 5 Hz, 250 Hz, and 2000 Hz were lower than those in the control group, and the difference was statistically significant. After treatment, the SOD in the observation group was higher than that in the control group, and the MDA and Hs-CRP were lower than those in the control group, where the difference was statistically significant. After treatment, the levels of blood pressure and blood glucose in the observation group were lower than those in the control group, and the difference was statistically significant. After treatment, LDL-C, TC, and TG in the observation group were lower than those in the control group, and HDL-C was higher than that in the control group. The difference was statistically significant. Conclusion: For patients with type 2 diabetes, lipoic acid can help improve the clinical treatment, which can improve the levels of blood glucose, blood pressure and blood lipid, increase nerve conduction velocity, and reduce the damage to sensory nerve subgroup.展开更多

Methods Enzyme linked immnunosorbent assay (ELISA) was used to determine the content of IL-2 and sIL-2R. The immunoadsorption was employed to examine the erythrocytic immune activity and its regulating function. Streptavidin-peroxidase(S-P) was used to determine the cell number of CD3 (cluster of differentiation3), CD4 and CD8. Results The content of IL-2 in the group with hypertensive cerebral hemorrhage was significantly lower than that in the control group (P<0.01), and the content of sIL-2R increased. Red blood cell C_ 3b receptor (RBC.C_ 3b R) and RBC immune adherence enhancing factor (RFEB) dropped greatly (P<0.01), while RBC immune complex rosette (RBC.ICR) and RBC immune adherence inhibiting factor (RFIR) increased greatly. The cell number of CD3 and CD4decreased (P<0.01) and there was no obvious change in CD8 (P<0.05). Conclusion The decrease of immune function was observed in patients with hypertensive cerebral hemorrhage. The determination of the content of IL-2, sIL-2R, erythrocytic immunity and the activity of T subgroup has an important clinical significance in the occurrence, development, treatment, and prognosis of hypertensive cerebral hemorrhage.展开更多
