Objective To explore the effects of botulinum toxin type A (BTX-A) on the F-waves of the tibial nerve and the walking ability of stroke patients.Methods Twenty stroke patients with spastic hemiplegia of a lower limb were randomly divided into experimental and control groups with 10 patients in each group.All received four weeks of conventional rehabilitation,including walking training,balance training and muscle strength training.In the experimental group,a total of 300 IU of BTX-A was injected into the gastrocnemius (200 IU) and soleus muscles (100 IU)before the start of routine rehabilitation,guided by using the electrical stimulation.Muscle tone was assessed using the modified Ashworth scale(MAS).Walking ability was assessed with the timed up and go test (TUGT) and a 10 m free walking test.F-wave parameters were recorded in the tibial nerve before,two weeks and four weeks after the injection.Results In the experimental group there was a significant difference in F-wave amplitude between those recorded before treatment and after two weeks of treatment.The control group showed no statistically significant difference.In experimental group there was also a statistically significant difference in triceps muscle tension before and after treatment which was not observed in the control group.Walking ability improved significantly in both groups.Conclusions Local injection of BTX-A into the lower limbs can reduce the F-wave amplitudes of spinal cord motor neurons.BTX-A injection combined with rehabilitation training can significantly improve the walking ability of stroke patients.

Objective To investigate the effects of penehyclidine (PHCD) pretreatment on nuclear factor kappa B ( NF-kB ) activity during lipopolysaccharide ( LPS )-induced acute lung injury ( ALl ) in neonate rats.Methods Thirty 7-day old Wistar rats of both sexes weighing 18-21 g were randomly divided into 3 groups ( n =10 each): group Ⅰ control (group C); group Ⅱ LPS; group Ⅲ PHCD. Group Ⅱ and Ⅲ received intraperitoneal ( group IP) LPS 3 mg/kg. In group Ⅲ PHCD 5 mg/kg was administered IP at 30 min before LPS respectively. The animals were killed at 4 h after LPS administration. The lungs were immediately removed. The W/D lung weight ratio was measured. The TNF-α, IL-1 βand IL-10 content in the lung were detected by ELISA and expression of NF-kB p65 was detected by immuno-histochemical staining.Results LPS significantly increased W/D lung weight ratio, TNF-α, IL-1 β, IL-10 content and NF-kB p65 expression in the lung as compared with control group. PHCD administered before LPS significantly attenuated the LPS-induced changes. Electron microscopy showed that PHCD before LPS significandy ameliorated the LPS-induced histological damages. Conclusion Pretreatment with PHCD can attenuate LPS-induced acute lung injury though inhibition of NF-kB activation and inflammatory response of lung tissue in neonate rats.

Objective To detect the levels of the mRNA expression of TIM-3,TIM-1,T-bet,GATA-3,IFN-γ,IL-4 and Galectin-9 in the peripheral blood monocytes (PBMCs) of the patients with Graves disease(GD),and to explore their potential role in the pathogenesis of GD.Methods We used fluorescence quantitative real-time reverse transcription-polymerase chain reaction to measure the mRNA expression of TIM-3,TIM-1 and other associated genes in PBMCs of 70 patients with GD and 22 healthy controls.In addition,we analyzed the relationship of TIM-3,TIM-1 and other associated genes.Results The expression of TIM-3 and TIM-1 mRNA in the PBMCs from GD patients were abnormally higher,the GD patients with Graves' ophthalmopathy group had significantly higher level of TIM-3 mRNA expression than that of GD patients without Graves' ophthalmopathy group,but no statistically significant difference was found in the expression of TIM-1 mRNA.Untreated GD patients had significantly higher level of TIM-3 mRNA expression than that of GD patients in recurrence group,however the expression of TIM-1 mRAN was opposite.But no statistically significant difference was found in TIM-3 mRNA expression of recovery GD patient and healthy control group.Though the expression of TIM-1 mRNA was significantly decreased,it was still higher than that of the normal control group.Conclusion TIM-3 and TIM-1 may participate in the occurrence,development and turnover of GD.TIM-3 or TIM-1 may prove to be an important target for developing new drugs and treatments to GD.

Objective:In order to ascertain the lateral operation and medial maxillectomy affect on nasal airway.Method:Report 16 cases of nasal cavity or nasal sinus neoplasm who were therapied by lateral rhinotomy and medial maxillectomy.They were observed by acoustic rhinometer (AR) and CT examination in 1～2.5 years after the surgery. Result:The feeling of nasal obstruct were disappeared in 3 months after the surgery. The nasal airway resistance(NAR) of the ill nasal cavity was markedly decreased after the surgery, and the total NAR were decreasing unmarkably. The mucous proliferation was notable only in the first year after surgery, and especially on remains of the inferior turbinate or extra wall of nasal cavity.Conclusion:Lateral rhinotomy operation and medial maxillectomy have less impact on nasal airway and the functions.

Objective:To study the distribution and expression of STAT6 and to examine the suggested roles of STAT6 in the pathogenesis of eosinophil infiltration in nasal polyps and to evaluate the role of STAT6 in the pathogenesis of nasal polyps.Method:All selected cases met the enrollment criteria.Thirty samples of nasal polyps were obtained from patients undergoing nasal polypectomy, and 10 samples of inferior turbinate tissues were from patients undergoing nasal septal reconstruction.STAT6 in nasal polyp tissues from 30 nasal polyposis patients and 10 samples of inferior turbinate tissues were detected with immunohistochemistry(SP) method.SPSS13.0 system was used to perform the statistical analysis.Result:The positive expression of STAT6 was significantly higher in epithelium of nasal polyps than that of the control. The number of eosinophils was significantly higher in epithelium of nasal polyps than that of the control. The difference between these two groups was statitically significant(P<0.05). STAT6 positive cell were localized on epithelium, gland cells and on inflammatory cell of nasal polyps. STAT6 expression was positively correlated with the recruitment of eosinophils in nasal polyps.Conclusion:The high expression of STAT6 protein and the suggested roles of STAT6 in the recruitment of eosinophils in nasal polyps may contribute to the initiation and progression of nasal polyps.
