Objective To investigate the effects of various intensity of 1 Hz repetitive transcranial magnetic stimulation (rTMS) on up-per limbs motor function after stroke. Methods From December, 2014 to December, 2015, sixty patients with ischemic stroke were random-ly divided into high density group (HD, n=20), low density group (LD, n=20) and control group (n=20). They all received routine rehabilita-tion and medication. The HD group received rTMS over contralesional motor cortex twice a day, while the LD group received rTMS once a day, and the control group received sham stimulation, 10 minutes a time for 10 days. They were tested with motor-evoked potentials (MEPs), Fugl-Meyer Assessment (FMA) of upper limbs and modified Barthel Index (MBI) before and after treatment. Results The ampli-tude of MEPs of the affected cortex, the scores of FMA and MBI were more in HD and LD groups than in the control group after treatment (P<0.01), and were more in HD group than in LD group (P<0.01). No serious side-effect was found. Conclusion rTMS was feasible for pa-tients with stroke to improve the upper limbs motor function. It is more effective as more times a day.

ObjectiveTo investigate the influence of dysphagia on nutritional status of stroke patients. MethodsSwallowing function of stroke patients were studied with videofluoroscopy. They were divided into study group and control group according to the results of videofluoroscopy (60 cases in each group). Their nutritional status were compared. ResultsThe triceps skin fold, mid-upper arm muscle circumference and serum albumin in the study group were lower significantly than those in the control group (P<0.05). ConclusionDysphagia is associated with poor nutrition in stroke patients.

Objective To investigate the therapeutic effects and relative mechanisms when constraint-induced movement therapy (CIMT) is used in patients with upper extremity disorders after head injury, and to compare the effects of CIMT with those of traditional rehabilitation (TR). Methods Thirty-six hemiparesis patients were randomly divided into a CIMT group and a TR group. Patients in the CIMT group were treated with intensive shaping training for 5 h a day for 3 weeks, as well as having their unaffected arms constrained. Meanwhile, the patients in the TR group were treated with traditional rehabilitation with no constraint of their unaffected arms. Motor activity logs (MALs) were compiled, and the Wolf Motor Function Test ( WMFT) and Barthel Index ( BI) were used to evaluate the therapeutic effects before treatment and at 0 d, 1 month and 3 month after treatment. Results Compared with the scores before treatment, the therapeutic effects were significant in the CIMT group, and the effect lasted to the follow-up period. Significant differences were also found between the CIMT group and the TR group in the improvement of dexterity by means of WMFT, and the usage of unaffected upper extremity as recorded in the MAL. There were no significant differences in therapeutic effects between the 2 week and 3 week treatments in the CIMT group. Conclusion CIMT significantly improved upper extremity function and ability in the activities of daily living ( ADL) of hemiplegia patients in the subacute period. The effectiveness of CIMT is superior to that of traditional rehabilitation methods.

ObjectiveTo investigate the effect of constraint-induced movement therapy(CIMT) on improving the flexibilty of upper extremities and the ability of daily living(ADL) of patients with hemiplegia.Methods36 patients with hemiparesis were randomized to two groups: CIMT and traditional rehabilitation(TR).In CIMT group,18 patients received intensive shaping training of 5 h/d,lasting 3 weeks, with the constraint of unaffected arms.In TR group,patients received traditional rehabilitation in the same times,without the constraint of unaffected arms. They were evaluated with Action Research Arm(ARA) Test and Barthel Index(BI) before intervention,immediate after intervention,4 and 12 weeks after intervention respectively.Patients in CIMT group were also evaluated with ARA tests 2 and 3 weeks after training.ResultsSignificant difference was found between CIMT and TR group on the improvement of ARA test(P<0.05).There was no significant difference between 2 and 3 weeks after training in CIMT group.Significant difference in BI was also found in CIMT group(P<0.01),but has not been found between CIMT and TR group.ConclusionCIMT significantly improved the flexibilty of upper extremities and ADL of patients with hemiplegia,which is superior to the traditional rehabilitation.

Objective To explore the effects of videofluoroscopic swallowing study (VFSS) in the assessment of dysphagia in post-stroke patients. To study the representation and rehabilitative outcome of dysphagia following stroke. Methods Seventy post-stroke patients and 80 normal adults were assigned to study group and control group and underwent VFSS. Abnormal signs on VFSS were compared between 2 groups. Aspiration patients received swallowing therapy for 4 weeks followed by VFSS again. Abnormal signs on VFSS were compared with those of pre-treatment. Results Penetration/aspiration, oral retention and pharyngeal retention occurred respectively at a frequency of 5.0%, 13.4% and 25.3% in control group in mild status, 45.0%,46.5%, 48.9% in study group in moderate to severer status. 10 times of silent aspiration were seen, accounting for 24.4% of all aspiration. The frequency of severe penetration/ aspiration decreased after the treatment (P

Objective To investigate the effect of glutamine in combination with umbilical cord blood mesenchymal stem cells ( MSCs) transplantation on intestinal ischemia-reperfusion injury in rats.Methods Umbilical cord blood mesenchymal stem cells were isolated, and were labeled with CM-DiI fluorescent dye.Eighty Sprague-Dawley rats were randomly divided into normal control group, ischemia reperfusion injury group, glutamine group, MSCs transplantation group and combined group with 15 rats in each group.The control group received saline enema.The injury group was treated with TNBS ( ethanol dilution) enema.The glutamine group at 1 h after TNBS received intravenous injection of 0.45 g/kg glutamine.The rats of MSCs transplantation group had tail vein injection of 1 ×1010/L umbilical cord blood mesenchymal stem cell suspension, and the combined group received intravenous injection of glutamine 0.45 g/kg and 1 ×1010/L umbilical cord blood mesenchymal stem cell suspension.ELISA was used to detect the midgut fatty acid binding protein (iFABP), interleukin 6 (IL-6), and superoxide dismutase (SOD) content in the rat serum.The water content of intestinal tissue was detected at 1 h and 3 h after reperfusion in each group.The expressions of NF-kB, Bcl-2 and caspase-3 mRNA and proteins in the rat intestinal epithelial cells after treated with glutamine in combination with MSCs were detected by RT-PCR and Western blot assays.Results The fluorescent tracer method revealed that the transplanted MSCs cells were distributed in the intestinal mucosal lymphoid tissues and glandular epithelial cells, indicating that MSCs might be involved in the repair process of intestinal ischemia-reperfusion injury.The content of serum IFABP and IL-6 in the injured group was significantly higher than that in the control group, while significantly reduced in the glutamine group, MSCs transplantation group and combined group, with the most obvious in the combined group.The content of SOD in the injury group was significantly lower than that in the control group, and significantly increased than that in the glutamine group, MSCs transplantation group, with the most striking in the combined group ( P<0.05 for all) .The water content of intestinal tissue in the injury group at 1 and 3 hours after reperfusion was significantly higher than that in the control group, significantly lower in the glutamine group, MSCs transplantation group and the combined group, with the most decreased in the combination group, and there was no significant difference between the glutamine group and MSCs transplantation group (P>0.05).Compared with the control group, the caspase-3 and NF-kB mRNA and protein expressions in the intestinal mucosal epithelial cells of the injury group were significantly increased, and the expressions of Bcl-2 mRNA and protein were significantly reduced ( P <0.05 ) , the expressions of caspase-3 and NF-kB mRNA and protein were significantly reduced in the glutamine group, MSCs transplantation group and combined group.The expressions of Bcl-2 mRNA and protein were significantly increased ( P<0.05) , while no significant difference was shown between the glutamine group and MSCs transplantation group (P>0.05), but there was a significant difference between these two groups and the combined group (P<0.05).Conclusions After treated with glutamine and MSCs transplantation, the degree of intestinal ischemia reperfusion injury is obviously reduced in rats.It may be mediated through inhibiting the expression of caspase-3 and NF-kB and promoting the expression of Bcl-2.

BACKGROUND:Bone marrow mesenchymal stem cel s can repair intestinal ischemia-reperfusion injuny by interfering inflammatory reactions after intestinal ischemia-reperfusion to protect intestinal barrier functions. In recent years, umbilical cord blood mesenchymal stem cel s are gradual y used as a substitute source of bone marrow mesenchymal stem cel s. OBJECTIVE:To investigate the effects of umbilical cord blood mesenchymal stem cel s on acute intestinal ischemia-reperfusion injury. METHODS:Umbilical cord blood mesenchymal stem cel s were induced, isolated in vitro and tracked by CM-DiI fluorescent labeling. Sixty-three Sprague-Dawley rats were equivalently randomized into three groups:control group received normal saline enema, intestinal ischemia-reperfusion injury group with ethanol diluted trinitro-benzene-sulfonic acid and transplantation group administrated with 1×1010/L umbilical cord blood mesenchymal stem cel suspension via the tail vein at 1 hour after trinitro-benzene-sulfonic acid modeling. At 3 days after transplantation, colon tissues were removed in each group to observe pathological changes of the intestinal tract by hematoxylin-eosin staining. Besides, expression of leptin mRNA in the colon tissues and cyclooxygenase-2 in the mucosa were detected by RT-PCR and immunohistochemistry method, respectively. RESULTS AND CONCLUSION:Transplanted umbilical cord blood mesenchymal stem cel s distributed in the intestinal lymphoid tissue and among glandular epithelial cel s, suggesting that these stem cel s might be involved in the process of intestinal ischemia-reperfusion injury repair. Compared with the control group, intestinal injury in the injury group was significantly aggravated, and most intestinal epithelial cel s shed;and the transplantation group appeared to have significantly reduced intestinal damage and significantly less cel shedding. Expression of leptin mRNA was significantly higher in the injury group than the transplantation group fol owed by the control group, and there were significant differences among the three groups (P<0.05). Additional y, expression of cyclooxygenase-2 in the injury group was significantly higher than that in the control group (P<0.05);compared with the injury group, expression of cyclooxygenase-2 was significantly lower in the transplantation group (P<0.05). To conclude, leptin and cyclooxygenase-2 may be involved in acute intestinal ischemia-reperfusion injury, and umbilical cord blood mesenchymal stem cel transplantation significantly lessens intestinal ischemia-reperfusion injury, which provides an experimental basis for human treating acute intestinal ischemic injury.

Objective To explore the expression and significance of signal transducer and activator of transcription 3 (Stat 3), glucose transporter protein 1 (GluT-1) and proliferation cell nuclear antigen (PC NA) in lesions of condylomata acuminata (CA). Methods SP immunohistochemistry method was used to measure the expression of Stat 3, GluT-1 and PCNA in tissue samples from 40 cases of CA and 20 normal skin controls. Results The positivity rates of Stat 3, GluT-1 and PCNA were 85.0% (34/40), 87.5% (35/40) and 85.0%(34/40), respectively in CA tissue, 35.0% (7/20), 30.0% (6/20)and 55.0% (11/20),respectively in the control tissue; statistical difference was observed in these rates between the two groups (all P ＜ 0.05). The expression intensity of Stat 3, GluT-1 and PCNA was also higher in CA tissue than that in the controls. In addition, the expression intensity of PCNA was correlated with that of Stat 3 and GluT-1in CA tissue (both P＜ 0.05). Conclusions There is an overexpression of Star 3, GluT-1 and PCNA in CA tissue, and the overexpression of Stat 3 and GluT-1 may be associated with the over-proliferation of CA tissue.
