A research on epilepsy source localization from scalp electroencephalograph based on patient-specific head model and multi-dipole model / 生物医学工程学杂志

Accurate source localization of the epileptogenic zone (EZ) is the primary condition of surgical removal of EZ. The traditional localization results based on three-dimensional ball model or standard head model may cause errors. This study intended to localize the EZ by using the patient-specific head model and multi-dipole algorithms using spikes during sleep. Then the current density distribution on the cortex was computed and used to construct the phase transfer entropy functional connectivity network between different brain areas to obtain the localization of EZ. The experiment result showed that our improved methods could reach the accuracy of 89.27% and the number of implanted electrodes could be reduced by (19.34 ± 7.15)%. This work can not only improve the accuracy of EZ localization, but also reduce the additional injury and potential risk caused by preoperative examination and surgical operation, and provide a more intuitive and effective reference for neurosurgeons to make surgical plans.

Mechanisms of Tong-Du-Huo-Luo Exercise in Treating Ankylosing Spondylitis / 国际中医中药杂志

Objective To expound the mechanism and the clinical features of Tong-Du-Huo-Luo exercise in treating ankylosing spondylitis.Methods Besides taking SASP per os,the patients in treatment group did Tong-Du-Huo-Luo exercise twice daily. Patients in control group took SASP only.The patients in both groups had accepted the treatments for 6 months.Results Compared with western medicine treatment,the Tong-Du-Huo-Luo exercise can bring better effects on ability of expanding chest,finger-floor distance,pulvinar-wall distance,and improving the results of Schober test and blood sedimentation test.Conclusions Tong-Du-Huo-Luo exercise is an effective method in treating ankylosing spondylitis patients.

Effect of intravenous drip infusion of cyclophosphamide with high-dose Astragalus injection in treating lupus nephritis / 中西医结合学报

OBJECTIVE: To observe the effect of high-dose Astragalus injection and cyclophosphamide (CTX) on infection, urine protein and immune function of the patients with lupus nephritis. METHODS: Forty-three patients diagnosed as systemic lupus erythematosus (SLE) complicated by kidney damage and qi-deficiency syndrome were randomly divided into trial group (n=23) and control group (n=20). Patients in both groups were treated for 3 months. Intravenous drip infusion of 0.8 g CTX was administered to all patients once a month, while intravenous drip infusion of 20 ml Astragalus injection was only administered to patients in the trial group every day for 12 days in each month. RESULTS: The decrease of active clinical symptom score after the treatment in the trial group was greater than that in the control group (P<0.05). The infection rates of the trial group and the control group were 4.35% and 25% respectively. The decrease of 24-hour urine protein and CD8, and the increase of red blood cell count and serum albumin in the trial group were greater than those in the control group, and there were significant differences between the two groups (P<0.05). White blood cell count in the trial group was decreased less than that in the control group after the treatment (P<0.05). CONCLUSION: High-dose Astragalus injection used together with CTX is more effective than CTX alone in decreasing infection rate and urine protein and improving immune function for patients with lupus nephritis.

Therapeutic Effect of Ziyin Yangxue Qingre Formula on Sjogren's Syndrome:A Clinical Observation on 33 Cases / 中医杂志

Objective To observe the therapeutic effect of Ziyin Yangxue Qingre Formula (Formula for enriching yin,nourishing blood and clearing heat) on primary Sjogren's Syndrome (pSS).Methods Totally 64 female pSS patients were randomized into a treating group (33 cases),and a control group (31 cases).The control group was administered Hydroxychloroquine Sulfate Tablet.In addition,the treating group was prescribed Ziyin Yangxue Qingre Formula.Three-month treatment was as one course.After one course of treatment,the changes in symptom scores,salivation quantity,tear quantity,and immuno-infective indices were observed to compare the effect between both groups.Results The total effective rate of the treating group(87.88%) was significantly higher than that (64.52%) of the control group (P
