Objective To investigate the effects of Xuezhikang (XZK) on carotid atherosclerosis plaque and blood lipids in patients with transient ischemic attack (TIA). Methods 65 patients with TIA were randomly divided into two groups: XZK group and control group.XZK group received XZK and Aspirin for 6 months, while the control group received Aspirin only. The intima-midia thickness (IMT) of carotid artery,the area of carotid atherosclerosis plaque, and levels of blood lipids, oxidized low density lipoprotein cholesterol (ox-LDL) and serum nitric oxide (NO) were measured before and after treatment.Incidence rate of cerebrovascular event in the two groups were compared in 6 months. Results After 6 months of treatment, the total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and ox-LDL concentrations decreased significantly in XZK group, however high density lipoprotein (HDL) and NO levels increased markedly (all P0.05).Conclusion It is shown that XZK not only effectively adjusts blood lipids, inhibits peroxide of lipids and protects vascular endothelial, but also regresses the atherosclerosis and stabilizes the plaque.

Objective:To study the clinical and genetic characteristics of familial paroxysmal exercise-induced dyskinesia with Parkinson-like manifestations in the elderly.Methods:Clinical data of 9 family members were analyzed, including 2 patients(both received treatment)consenting to appropriate therapy and prediction protocols.DNA was extracted from peripheral blood samples, and then second-generation sequencing mutation screening.Results:The tremor of two probands in the family was completely brought under control by oxcarbazepine treatment.In 5 family members, a heterozygous mutation of base G>C in exon 2 c. G366C: P.QCon122H at position 29824741 of the PRRT2 gene was found, resulting in the mutation of the amino acid at 122 from glutamine to histidine, which was predicted by SIFT and M-CAP to be harmful.Sanger sequencing of pedigree samples showed that the sisters, brothers and nephews of the proband were heterozygous and their nieces were of the wild type.Conclusions:Q122 of PRRT2 protein can cause the Parkinson-like limb tremor phenotype, and antiepileptic drugs are also effective for paroxysmal exercise-induced dyskinesia in the elderly.
