Objective To evaluate the diagnostic value of sympathetic skin response(SSR)in patients with vestibular vertigo.Methods SSR tests were performed on 1 20 patients with acute vestibular system vertigo,including 70 cases of central vertigo and 50 eases of peripherM vertigo.60 healthy subjects were also examined to serve as controls.Results In those with central vertigo,the abnormality rate in the SSR results was 87.1%(61/70).SSR latency was longer and its amplitude wag lower than in those with peripheral vertigo and in the heMthy controls.In those with peripheral vertigo the abnormality rate was 18.0%(9/50),but the average latency and amplitude were not significantly different from those of the healthy controls.Conclusion Persons with acute central vestibular vertigo may have sympathetic nerve dysfunction.SSR test results can be used as an electrophysiological index to distinguish central from peripheral vestibular vertigo.

Objective Analysis and adscription of volatiles from Guizhi Tang and study on its improvement of the learning and memory in dementia mice induced by scopolamine.Methods The volatile oil from Guizhi Tang(GZT),Guizhi and Shengjiang was extracted using steam distillation method and was analyzed by GC-MS. Morris water maze and step-down test were carried out for obtain the difference of the learning and memory improvement in 40 ICR mice from randomized groups, such as the control group, the model group, the donepezil group (2 mg/kg), the low dose of volatile oil of GZT (5 mg/kg), and the high dose of volatile oil of GZT (20 mg/kg), and ACh, AchE, BchE and chE in serum were detected by ELISA. Results Among 38 identyfied volatile ingredients from GZT, 18(44% in weight) was from Guizhi, and 9 was from Shengjiang. Compared with the model group, the low and high dose of GZT volatile oil significantly increased swimming distance ratio in destination quadrant (26.74% ± 16.42%vs.9.42% ± 8.50%, P<0.05); goal quadrant time scale (43.51% ± 25.12%vs. 14.50% ± 12.23%,P<0.05)) increased significantly than the model group ; the number of errors in the experiment platform (1.63 ± 1.19vs. 0.25 ± 0.46, P<0.05) obviously increased than model group ; platform test in the made errors times (0.57 ± 0.98vs. 4.43 ± 2.4, P<0.05) significantly reduced. The GZT total volatile oil groups significantly reduced cognitive obstacles small rat serum in the cholinester enzyme (chE) (140.90 ± 3.27, 144.79 ± 6.71vs. 134.49 ± 3.36,P<0.05); acetylcholinesterase (AchE) (3.30 ± 1.31, 3.94 ± 0.78 vs.8.52 ± 3.39,P<0.05); butyrylcholinesterase (BchE) (3.22 ± 0.45, 3.66 ± 0.53vs. 7.99 ± 0.79,P<0.05); and acetylcholine (Ach) (4.10 ± 0.38, 3.03 ± 0.25vs.1.72 ± 0.50, P<0.05) significantly increased.Conclusions The GZT volatile oil mainly from Guizhi and Shengjiang can improve the learning and memory ability in dementia mice induced by scopolamine via a cholinergic mechnism.

Objective To systematically review the efficacy and safety of repetitive transcranial magnetic stimulation (rTMS)for post-stroke dysphagia. Methods The clinical trials about rTMS for post-stroke dysphagia were searched on Pubmed,EMbase,MEDLINE,Cochrane library,China National Knowledge Infrastructure (CNKI),Chinese BioMedical Literature Database on disc (CBMdisc),and Wanfang database with computers. Two independent reviewers selected the literatures by the inclusion and exclusion criteria,data extraction and cross-checking,and then conducted the analysis. Results A total of seven trails (228 patients,136 of them in a rTMS group and 92 in a control group)were included. Four randomized controlled trials (RCTs)were used for Meta-analysis (54 patients in the rTMS group,42 in the control group). The other three non-RCTs were only reviewed systematically. (1)Meta-analysis showed that the improvement of swallowing function score after rTMS was better than that of the control group (SMD=1. 73,95%CI 0. 45 to 3. 01;P=0. 008). (2)After high-frequency rTMS (>1 Hz),there was significant difference in the improvement of swallowing function score between the two groups (SMD=1. 60,95%CI 0. 10 to 3. 11;P=0. 04). Compared to the control group,there were also significant differences in the improvement of some swallowing function scores in low-frequency rTMS (1 Hz),suggesting the potential advantages of low-frequency therapy. (3)After rTMS,there was no significant difference in the improvement of Barthel index in patients with stroke compared with the control group (MD= -21. 60,95%CI-36. 21 to-7. 00;P=0. 004). (4)In terms of adverse reactions,seven trials did not report any adverse events, such as headache,tinnitus or epilepsy,etc. Conclusion Using rTMS may significantly promote the recovery of swallowing function for patients with post-stroke dysphagia,and it is both safe and effective.
