Objective To observe the effects of neuromuscular electrical stimulation (NMES) at different frequency on post-stroke pharyngeal dysphagia.Methods Forty-five stroke survivors with pharyngeal dysphagia were randomly divided into treatment group 1,treatment group 2 and treatment group 3,eachof 15 patients.Patients in the treatment group 1,2 and 3 received NMES once,twice and three times a day respectively.All the 3 groups were given conventional swallowing training.The swallowing function classification was conducted before treatment,as well as 1,2 and 4 weeks after the treatment.Before and 2 weeks after the treatment,X-ray examination of swallowing (VFSS) was taken to assess the swallowing function,and the average treating days of the 3 groups were compared.Results The swallowing function classification showed that in treatment group 1 and 2,significant improvement was observed at this time point than that at the previous time point (P＜0.05).In treatment group 3,after 1 and 2 weeks of treatment,significant improvement was found compared to those previously,but there was no difference between after 2 weeks and 4 weeks of treatment.At the same time points,the treatment group 2 and 3 showed higher efficiency than the group 1 (P＜0.05).And compared with the treatment group 2,the treatment group 3 showed higher efficiency after 1 and 2 weeks of treatment (P＜0.05),but there was nosignificant difference after 4 weeks of treatment.Two weeks after the treatment,the average VFSS scores of all groups were significantly higher than those before the treatment (P＜0.05) and that of treatmentgroup 2 (7.600± 1.793) and 3 (8.900± 1.636) was significantly higher than that in treatment group 1 (6.700±1.873),as was that of group 3 compared to group 2.Compared with the treatment group 1 and 2,the average treatment days decreased significantly in treatment group 3 (P＜0.05).Conclusion NMES is effective in treating pharyngeal dysphagia after stroke.And within a certain range (1 to 3 times every day),with the increasing of daily treatment frequency,the effectismore significant and the average time of treatment shortens.

Objective To investigate and analyze the depression situation and the influencing factors in elderly inpatients.Meth-ods The cross-sectional method was used to conduct the investigation on randomly selected 125 elderly inpatients by the geriatric depressive scale(GDS)and the general personal questionnaire.Results Among 125 elderly inpatients,41 cases were depressed eld-erly inpatients,accounting for 32.8%.Disease,marital status,length of hospital stay,self-care ability,medical expenses and hobbies were the influence factors of the elderly inpatients(P<0.05).Conclusion The prevalence of depression in the hospitalized elderly patients is relatively high,the geriatrics should pay attention to it.

MicroRNA (miRNA) is newly discovered,a class of small non-coding RNA which plays critical roles in the regulation of gene expression at the posttranscriptional level by either degrading or blocking translation of messenger RNA targets.Growing evidence that some miRNAs have crucial roles in controlling and modulating immunity,while dysregulation of miRNAs can lead to autoimmunity,and miRNA-146 seems to be a popular topic discussed much.Thyroid associated ophthalmopathy (TAO) is an organ specificity autoimmune disease which is closely associated with Graves disease.Although many clinical and experimental investigations have been done,the precise aetiology and pathogenesis of TAO remain largely unclear.Here we review the roles of miRNA-146 regulation in immune functions and in the development of autoimmunity and autoimmune disease,and outlook for the roles of miRNA-146 in the pathogenesis of TAO.

Objective To analyze the concentration changes of serum hypoxia stress peptide (HSP)and plasma nitrogen monoxidum(NO)in the entering mountain rapidly man and to explore the importance of HSP and NO in adaptation of man to altitude hypoxia.Methods The levels of serum HSP and plasma NO2-/NO3-were measured from 106 entering mountain rapidly men,105 altitude in habitant,105 altitude immigrant and 104 plain healthy controls,respectively by chromatometry and NO2-/NO3-reagent.Furthermore,the content of serum HSP was determined in 106 entering mountain rapidly men,respectively at the time of 24 h,48 h,76 h,l week and 1 month after entering mountain.Results The level of serum HSP was significantly higher in entering mountain rapidly men than in habitant,immigrant and plain controls(P＜0.05),while there was no statistical difference between in habitant,immigrant and plain controls(P＞0.05).At 24h after entering mountain rapidly,the level of serum HSP was significantly increased and reached the peak.At 48h and 76h,it was slightly decreased,but still maintained a high level.At 1 week and 1 month,it gradually and significantly went down,but was still significantly higher than that in plain controls.Similarly,the level of plasma NO2-/NO3-was significantly elevated in entering mountain rapidly man,compared with inhabitant,immigrant and plain controls(P＜0.05).It was lower in inhabitants and immigrants than plain controls,but the difference was not statistically significant(P＞0.05).Conclusion The present results demonstrated that the levels of serum HSP and plasma NO were significantly up-regulated in healthy adults after en tcring mountain rapidly in order to adapt to altitude stress,and restored gradually to the normal level as time went by.
