OBJECTIVE To study the synchronous electromyograhic features of suprahyoid muscles [anterior digastric muscle(AD), posterior digastric muscle(PD),stylohyoid muscle(STH),mylohyoid muscle(MH)and geniohyoid muscle(GH)] and intrinsic laryngeal muscles [lateral cricoarytenoid muscle(LCA)and posterior cricoarytenoid muscle(PCA)]. METHODS Synchronous electromyograhic features of 13 dogs were observed under the circumstances of breath, swallowing and phonation. RESULTS ①AD, PD, STH, MH, GH and PCA discharged during inspiratory phase, while LCA discharged during expiratory phase. ②During swallow, suprahyoid muscles and LCA showed intensive synchronous discharge. The myoelectricity of PCA was suppressed while myopotential can be detected during intermission. ③During phonation, AD, PD, LCA and PCA showed an intensive synchronous discharge, while emergence time of PCA was later. GH and STH showed no myoelectricity activities. CONCLUSION①During phonation and swallowing, MH is synchronized with LCA. It can be chosen as the backup muscle for the reestablishment of glottic adduct function. ②During inspiratory phase, GH is synchronized with PCA. It can be chosen as the backup muscles for the reestablishment of vocal cord abduct function.

Coronary heart disease(CHD) is the leading cause of death among women worldwide.Recent technological advances in cardiovascular diagnosis and treatment have not led to significant declines in mortality for women with CHD when compared to the dramatic declines for men.Owing to the gender differences of physiology and social circumstances,women with CHD may have different manifestations as compared to men with CHD.Recently,research has shown that women with CHD had mainly the following characteristics:special risk factors,atypical ischemia symptoms,multiple risk factors and comorbidities at initial physician consultation,higher under-treatment rate and higher mortality rate.At the same time,most CHD researches have paid little attention to women.Therefore,the current CHD guidelines may not be completely suitable for women.In order to improve the prevention and treatment of CHD in women,we advocate to enhance research and clinical work for women with CHD.

Background:MicroRNAs ( miRNAs ) is a class of small non-coding RNAs that regulate gene expression at posttranscriptional level. They are considered to play a critical role in the tumorigenesis and development of various tumors. Aims:To identify the recurrence-specific miRNAs in peripheral blood of patients with recurrent colorectal adenoma by miRNA array for providing sensitive and specific molecular markers for recurrence prediction. Methods:Fifty colorectal adenoma patients who had undergone polypectomy by colonoscopy were re-examined from Aug. 2012 to Sep. 2013. Four recurrent and four non-recurrent patients were selected and miRNA array was used to detect the expression profiles of miRNAs in peripheral blood samples. Differentially expressed miRNAs were identified between recurrent and non-recurrent patients. Real-time PCR was applied to verify the differentially expressed miRNAs identified by microarray. Results:Seven up-regulatedmiRNAs(hp hsa-miR-548ai,hsa-miR-4446-3p,hsa-miR-139-3p,hsa-miR-27a-5p,hsa-miR-10a,hsa-miR-23a and hsa-miR-486-3p)and 4 down-regulated miRNAs( hsa-miR-124,hsa-miR-3613-5p,hsa-miR-495 and hsa-miR-485-5p)were identified by microarray between recurrent and non-recurrent patients. Among them,seven miRNAs were validated by real-time PCR as consistent with microarray. Conclusions:Some differentially expressed miRNAs may be involved in the recurrence of colorectal adenoma,which gives clues for further investigation on recurrence predictors.
