ABSTRACT
Objective:To observe the effect of 3 Hz and 10 Hz repetitive transcranial magnetic stimulation (rTMS) on upper limb motor function and activities of daily living in patients with ischemic stroke. Methods:From June, 2016 to September, 2017, 60 inpatients with ischemic stroke were randomly divided into sham rTMS group (n = 19), 3 Hz-rTMS group (n = 21) and 10 Hz-rTMS group (n = 20). All the patients received routine training and their own rTMS for two weeks. Their rest motor threshold (RMT) was measured, and they were assessed with modified Ashworth Scale (MAS), Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and modified Barthel Index (MBI) before and after treatment, and at six weeks follow-up. Results:There were 48 patients completing the trial, while five in 3 Hz-rTMS group, five in 10 Hz-rTMS group and two in the sham rTMS group dropped. The RMT increased in 3 Hz and 10 Hz rTMS groups (t > 2.390, P < 0.05) after treatment, but there was no significantly difference among the three groups (F = 0.164, P > 0.05). The MAS scores of elbow and wrist decreased gradually over time in 3 Hz and 10 Hz rTMS groups (P < 0.05), and the MAS scores of elbow was less in 3 Hz and 10 Hz rTMS groups than in the sham rTMS group at follow-up (P < 0.05). The interaction of time and group was significant on the FMA-UE scores (F = 14.243, P < 0.001), and the FMA-UE scores improved more in 3 Hz and 10 Hz rTMS groups than in the sham rTMS group at different stages (P < 0.01). The interaction of time and group was not significant in MBI score (F = 1.481, P > 0.05), and there was no significant difference among the three groups at any time (F < 2.925, P > 0.05). Conclusion:Both 3 Hz and 10 Hz rTMS can promote the recovery of upper limb motor function in ischemic stroke patients safely and effectively, and 10 Hz rTMS is recommended as less time is needed.

ABSTRACT
@#Objective To observe the effect of high-frequency repetitive transcranial magnetic stimulation(rTMS)on hand function in patients after stroke. Methods From June,2016 to September,2017,30 stroke patients were randomly divided into control group(n=30)and experimental group(n=30).Both groups received routine training after sham rTMS or 3 Hz rTMS.Fugl-Meyer Assessment(FMA),modified Ashworth Scale(MAS)and modified Barthel Index(MBI)were used to evaluate the hand function and the activities of daily living before and after treatment. Results Finally 27 patients completed the experiment.After treatment, the FMA score increased in both groups (Z>2.070, P<0.05), and the difference value was higher in the experimental group than in the control group (Z=-2.296,P<0.05);the MAS score improved in the experimental group(Z=-2.456,P<0.05),no difference was found in the control group(Z=-0.816,P>0.05),and the difference value was higher in the experimental group than in the control group(Z=-2.792,P<0.01);the MBI score improved in both groups(t>3.085,P<0.01),howev-er,no difference was found in the MBI score and the difference value between two groups(t<0.246,P>0.05). Conclusion High-frequency rTMS could promote the hand function in patients after stroke.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the prevalence of cagA, vacA, and iceA genotypes in the isolated strains of Helicobacter pylori (H.pylori) from children with gastroduodenal diseases in Jiangxi, China, as well as the association between cagA, vacA, and iceA genotypes and the type of gastroduodenal diseases.</p><p><b>METHODS</b>The samples of gastric antral mucosa were collected from 316 children with gastroduodenal diseases in Jiangxi, and a total of 107 strains of H.pylori were isolated. The genomic DNA of these strains was extracted, and PCR was used to determine the ureA, cagA, vacA, and iceA genotypes.</p><p><b>RESULTS</b>Of all the 107 isolated strains of H.pylori, the detection rates of ureA and cagA genes were 100% (107/107) and 94.4% (101/107) respectively. The overall detection rate of vacA gene was 100% (107/107), and the detection rates of vacAs1a, vacAs1c, vacAm1, and vacAm2 genes were 74.8% (80/107), 25.2% (27/107), 29.9% (32/107), and 69.2% (74/107) respectively, with both vacAm1 and vacAm2 genes detected in 0.9% (1/107) of all H.pylori strains. In the chimera of vacA gene, the detection rates of vacAs1a/m1, vacAs1a/m2, vacAs1c/m1, and vacAs1c/m2 genes were 26.2% (28/107), 51.4% (55/107), 3.7% (4/107), and 17.8% (19/107) respectively (P<0.001). The detection rates of iceA1 and iceA2 genes were 79.4% (85/107) and 9.3% (10/107), respectively (P<0.001), and both iceA1 and iceA2 genes were detected in 7.5% (8/107) of all strains. The detection rates of the genotypes of H.pylori showed no significant differences between the peptic ulcer, chronic gastritis, and duodenal bulbar inflammation groups (P>0.05).</p><p><b>CONCLUSIONS</b>The dominant genotypes of H.pylori are cagA, vacAs1a/m2, and iceA1, and there are mixed infections with H.pylori strains of different genotypes in children with gastroduodenal disease from Jiangxi, China. The genotypes of H.pylori are not associated with the type of gastroduodenal disease.</p>
