Objective To investigate the clinical efficacy of the self-retaining laryngeal microsurgical operation in the treatment of Reinke ’ s edema of vocal cords . Methods There were 24 cases of Reinke ’ s edema who were treated with self-retaining laryngoscope mucosal stripping surgery of vocal cords from January 2004 to December 2009 ( traditional group ) , while another group of 32 cases of Reinke ’ s edema were treated with self-retaining laryngoscopic microsurgery lateral submucosal incision micro-flap operation of vocal cords from January 2010 to December 2015 ( laryngeal microsurgery group ) .The two groups were executed with electronic laryngoscopy and subjective voice evaluation GRBAS ( The Speech and Language Institute of Japanese in 1979, G: Grade, R:Roughness, B:Breathness, A:Asthenia, S:Strain) in pre-operation and post-operation (1 week, 3 weeks, 8 weeks).The wound healing time of vocal cords , hoarseness improved time and voice improvement were retrospectively compared between the two groups . Results The patients in laryngeal microsurgery group had earlier voice hoarse improvement and more rapid mucosal epithelial of vocal cords recovery time in post-operation as compared with the patients in the traditional group [voice improving time, (7.3 ±1.9) d vs. (11.3 ±2.7) d, t=-6.481, P=0.000;mucosal epithelial of vocal cords recovery time , (12.2 ±3.1) d vs.(20.1 ±3.4) d, t=-9.062, P=0.000].The results of pre-operative voice evaluation with GRBAS showed no significant differences between the two groups, but the results of post-operative evaluation of each session (1 week, 3 weeks, 8 weeks) showed that the main data were statistically different.The GRBAS score of laryngeal microsurgery group was lower than that of traditional group in post -operation, especially after 8 weeks (8 weeks after post-operation, G:1.0 ±0.8 vs.1.6 ±0.2, t=-3.584, P=0.000; R:1.0 ±0.9 vs. 1.5 ±0.4, t=-2.536, P=0.014;B:1.0 ±0.6 vs.1.4 ±0.5, t=-2.647, P=0.011).In laryngeal microsurgery group, 24 cases were cured , 5 cases were effective and 3 cases were invalid , contrasting in the traditional group with 11 cases of cured , 7 cases of effective and 6 cases of invalid respectively, with a significant difference (Z=-2.239, P=0.025).No significant difference in effective rate between the two groups [90.6%(29/32) vs.75.0%(18/24),χ2 =1.459, P=0.227]. Conclusion The clinical efficacy of self-retaining laryngoscope microsurgery in the treatment of Reinke ’ s edema of vocal cords is faster and better comparing traditional operation , with a more significant pronunciation quality improvement .

Recent studies have demonstrated that hyperhomocysteinemia is an independent risk factor for stroke,which may cause vascular endothelial injury by multiple mechanisms,destroy blood coagulation and fibrinolytic systems,and influence on lipid metabolism.Methylenetetra hydrofolate reductase(MTHFR)is a key enzyme of homocysteine metabolic pathway in the human body.If it is insufficient or its activity decreases,it will directly result in the accumula tion of homocysteine in the human body,and callse hyperhomocysteinemia.Although a number of studies have found that MTHFR gene mutation is the main cause of MTHFR insufficient and its activity decrease,the correlation between MTHFR gene mutation and ischemic cerebral vascular disease is quite controversial now.This article reviews the relationship between MTHFR gene polymorphisms and ischemic stroke.

Objective To evaluate the difference of myocardium strain between myocadial infarction and ventricular aneurysm (VA) by two-dimensional speckle-tracking imaging in rabbits.Methods 26 healthy New Zealand white rabbits were enrolled in this study,6 were put into the control group and 20 in the experimental group.models of myocardial infarction concomitant with VA were prepared by the ligation of the middle segment of left anterior descending artery and left circumflex artery.At 4 weeks after the procedure,according to the pathological inspect and echocardiography for whether VA formed,the experimental animals were divided into the VA group and the myocadial infarction group.Echocardiography was performed to measure the LV cavity size and cardiac function.Radial strain rate (SrR) and circumferential strain rate(SrC) indexes were measured by 2D-STI software for each animal at the level of apex in left ventricular short-axis view,and then calculated the strain rate decrease percentage in each segment.Results 1)Compared with the control group,SrR-S,SrR-E,SrR A,SrC-S,SrC-E,SrC-A in all segments were reduced significantly in the VA group and the myocadial infarction group (P ＜ 0.05),the VA group was the most significant.2)Compared with the myocadial infarction group,the strain rate decrease percentage of SrR-S,SrR-E,SrR-A,SrC-S,SrC-E,SrC-A in all segment had significant in the VA group.Comparison between the each section,the strain rate decrease percentage of SrR-Santerior wall,SrR-Sateral wall,SrC-Santerior wall,SrC-Slateral wall were the most significant.3)There were the tighter relationship between the strain rate decrease percentage of SrR-Santerior wall,SrC-Santerior wall,SrR-Slateral wall,SrC-Slateral wall and left ventricular ejection fraction (r =0.82,0.72,0.75,0.71,repectively,all P ＜ 0.05).4) The ROC curve analysis showed that when the strain rate decrease percentage was 60％ as the critical point,the strain rate decrease percentage of SrC-Santerior wall,SrC-Slateral wall,SrR-Santerior wall,SrR-Slateral wall had a sensitivity of 83.30 ％,84.40％,83.30％,67.70％％ and a specificity was 73.60％,78.20％％,69.70％,83.30％ for prognosis ventricular aneurysm,repectively.Conclusions After ventricular aneurysm formation,anterior and lateral wall myocardial strain were give priority to the myocardial mechanics reconstruction,thus systolic myocardial strain rate decrease percentage can be important indicator of infarction myocardial developing into ventricular aneurysm.

OBJECTIVE: To explore the diagnosis, treatment and surgical approaches of parapharyngeal space tumors. METHOD: This retrospective study consisted of 112 patients with parapharyngeal space tumors underwent surgeries. The data included clinical symptoms and signs, pathological types, imaging examinations, surgical approaches and postoperative complications. RESULT: Computerized tomography (CT), magnetic resonance imaging (MRD and digital subtraction angiography (DSA) made clear the tumor size, localization and its relation to adjacent structures. The postoperative histopathology varied and showed benign in 98 cases consisting of salivary gland tumors (52 cases), neurogenic tumors(33 cases) and other types (13 cases). During the 3 years follow-up period, local recurrence appeared in 3 patients with salivary pleomorphic adenoma and 1 patient with neurofibromatosis. These recurrent tumor cases were cured with second surgery. In 14 patients with malignant tumors reported, 8 cases survived for 5 years, 2 cases (1 adenoid cystic carcinoma and 1 carcinoma in pleornorphic adenoma) recurred in the two and a half years cured with second surgery affiliated radiation therapy through 3 years follow-up time and the rest were followed up 1 to 3 years without recurrence. Peripheral facial paralysis was observed in 25 patients, and 3 patients experienced hypoglossal nerve palsy. Only 1 patient encountered vagus nerve injury, and 2 patients appeared Horner's syndrome, and 4 patients endured Frey syndrome. Gills leakage was discovered in 3 cases and cavity infection was noted in 1 patient. CONCLUSION CT, MRI and DSA were important in the diagnosis and differential diagnosis of parapharyngeal space tumors. The key to successful treatment is knowing the anatomy of the parapharyngeal space, preoperative assessment and appropriate surgical approach.
