[ABSTRACT]OBJECTIVETo observe the correlation of laryngopharyngeal reflux disease(LPRD) with anxiety and depression symptoms, and to study the treatment efficacy.METHODSThe clinical data of 98 cases with LPRD were retrospectively analyzed from March 2014 to December 2014. According to the result of the Hospital Anxiety and Depression Scale(HADS) scores, 56 cases were normal and 42 cases were abnormal. The abnormal group were randomly divided into treatment group(21 cases) and control group(21cases).The control group and normal HADS group were treated by omeprazole capsules, treatment group was given omeprazole capsules and flupenthixol melitracen tablets with psychological adjustment.RESULTS The effective rate of treatment group and control group was 66.67% and 14.29% respectively, the difference was statistically significant(χ2=11.958,P<0.05). The difference between the normal HADS group and the control group also was significant(χ2=8.843,P<0.05). The difference between the normal HADS group and the treatment group was not significant(χ2=1.372,P>0.05).CONCLUSION Laryngopharyngeal reflux in some patients exist state of anxiety or depression. Individualized treatment in patients with laryngopharyngeal reflux can improve the efficacy.

Hyperhomocysteinemia, which is an independent risk factor for atherosclerosis, may cause aberrant methylation and dysregulation of gene expression, but the characteristics of the aberrant methylation and its key links involved in its pathogenic mechanisms are still poorly understood. The effect of hyperhomocysteine on DNA methylation in vascular smooth muscle cells, its characteristics and the underlying mechanism of Hcy-induced changing in DNA methylation patterns were investigated. Clinical relevant concentrations of homocysteine was added into the cultured vascular smooth muscle cells of the Homo sapien umbilical vein for 24 h. The level of SAM and SAH was detected by HPLC. The activity of SAH Hydrolase was detected by real-time quantitative reverse transcription-PCR and Western blotting analysis. The level and patterns of DNA methylation were measured by endogenous C-5 DNA methyltransferase(C-5 MT-ase) activity and capacity of genomic DNA to accept methyl groups and methylation-dependent restriction analysis. The results indicated that an increased Hcy concentration induced elevated SAH, declined SAM and the ratio of SAM/SAH, reduced expression of SAH Hydrolase, but increased activity of C-5MT-ase. The methylation status of gDNA analyzed by methyl-accepting capacity of gDNA uncovered a demethylation process in gDNA, or homocysteine-caused hypomethylation in gDNA.With different methylation-dependent restriction endonucleases, the aberrant demethylation was found to prefer C↓CGG sequences to CpG islands. The impacts of different dosage of Hcy showed that the varied detrimental effects of Hcy could be attributed to different concentrations via different mechanisms. In mild and moderate hyperhomocysteinemia, the Hcy may primarily influence the epigenetic regulation of gene expression through the interference of transferring methyl-group metabolism, while in more higher Hcy concentration, the notorious impacts may be more directly caused via oxidative stress, apoptosis, inflammation etc.

Objective To investigate the effect of cell proliferation and apoptosis induced by Pingyangmycin (PYM)and dexamethasone (DEX) on human umbilical vein endothelial cells (HUVEC)in vitro, so as to provide therotical evidence for treatment of aneurysm with PYMand DEX. Methods Control, PYM, DEX and PYM group were established after HUVEC were cultured for 24 hours. Cell morphology was observed by inverted microscope.The effect of cell proliferation and apoptosis were detected with CCK-8reagents and flow Cytometry. The apoptotic protein expression of caspase-3 was testedthrough Western blot. Results Descend of adherent cell density and the ascend of floating cells could be observed after treated with PYM and DEX for 24 hours. HUVEC could be inhibited effectively with concentration-dependent on PYM and DEX. The significant statistical difference of cell apoptosis rate between the group used for PYM alone and the group combined low-concentration PYM with DEX through Flow Cytometrywas found. There was significant statistical difference of apoptotic protein expression of caspase-3 through Western blot compared with the group used for PYM alone and the group combined low-concentration PYM with DEX. Conclusion PYM and DEXcould inhibitthe proliferation of HUVEC alone. The better effects could be observed combination low-concentration PYM with DEX , the mechanism of which might beapoptosis with low-concentration PYM and necrosis with high-concentration PYM.

OBJECTIVE To explore the expression of Maspin in invasive fungal rhinosinusitis (IFRS) and the value of Maspin in the diagnosis of IFRS. METHODS Forty two cases of fungal rhinosinusitis (FRS) were set as the experimental group, which included 12 cases of IFRS and 30 cases of noninvasive fungal rhino-sinusitis (NIFRS). At the same time, 30 cases of chronic rhino-sinusitis were set as control group. Immunohistochemistry (IHC) was used to detect the expression of Maspin. RESULTS Compared with the control group, the expression of Maspin in FRS group decreased statistically (t=-3.367, P<0.05). The IFRS group, compared with other two groups, had the lowest expression of Maspin (t=-3.390, P<0.05; t=-4.143, P<0.05). By using Maspin score of 5.70 as the cut-off point, the sensitivity and specificity for the diagnosis of IFRS was 91.7% and 88.3% respectively. CONCLUSION The expression of Maspin is very low in IFRS group. Down-regulation of Maspin expression may be a potential indicator for diagnosis of IFRS.

Objective:To explore the expression and distribution of ciliary neurotrophic factor (CNTF) in laryngeal nerve degeneration and regeneration. Methods:Transection of the recurrent laryngeal nerves in 8 dogs and suture following transection in 12 cases were performed. Both proximal and distal ends of transected or sutured region were sectioned at various survival times for CNTF immunohistochemistry and CNTF mRNA in situ hybridization. The area and intensity of reactive product were measured by computer image processing system. Results:After nerve transection, reactive product of CNTF mRNA and its protein reduced rapidly in distal stumps, after neurorrhaphy, they were observed in thin Schwann cell processes ensheathing axons and not found in the proliferating Schwann cells which didn′t ensheathe axons. CNTF immunoreactivity was also detected in the regenerated nerve axons. CNTF expression increased with survival time, but even at the longest survival time, it was still significantly less than that in intact nerve. The same change was observed in a short segment proximal to the transected or sutured region. Conclusion:CNTF expression is in the down regulation and is collected with Schwann cell axon in peripheral nerve degeneration and regeneration. The changed distribution of CNFT might provide a supportive environment for axonal regeneration.

OBJECTIVE:
To compare the effectiveness of vocal cord cyst excision with electronic laryngoscope (EL) and self-retaining laryngoscope (SRM).
METHOD:
Nightly-two patients, diagnosed as vocal cord cyst with strobolaryngoscope or electronic laryngoscope, were randomly divided into two groups. One group was 48 cases treated with electronic laryngoscope and another group was 44 cases treated with self-retaining laryngoscope. Electronic laryngoscopy examination and voice function assessments were performed to all patients, preoperatively and postoperatively at one week, three months and six months.
RESULT:
One failed cases under SRM, difficult exposure of glottic portion, were treated under EL. The recurrence rate of the two groups was of no statistical significance in three months after operation. Voice function assessment of the two groups was of no statistical significance at one week, three months and six months after operation.
CONCLUSION
The operation under electronic laryngoscope is a minimal invasive procedure to the laryngeal mucosa. Electronic laryngoscope had advantages such as clear view, accurate operation. Furthermore, it can be used for those that could not be treated under self-retaining laryngoscope.

Objectives To explore therapeutic effect,indication and timing of nerve decompression for traumatic recurrent laryngeal nerve injury inducing vocal cord paralysis. Methods A total of 42 patients with recurrent laryngeal nerve injury inducing vocal cord paralysis within six months, were divided into nerve decompression group (15 cases), end to end anastomosis of recurrent laryngeal nerve group (six cases) and nonsurgical treatment (21 cases). Nerve decompression was performed in the patients who were operatively found to have compressing sutures or compression due to cicatricial hypertrophy. Results In 13 patients with a course less than four months, nerve decompression restored normal functional adductory and abductory motion of the vocal cord in 11 patients and motionless in two. Although functional motion of vocal cord was not seen in two patients with a course less than four months and two longer than four months, the mass and tension of the reinnervated vocal cord became much the same as the contralateral normal vocal cord, thus resuming symmetric vibration of the vocal cords and physiological phonation. End-to-end anastomosis of recurrent laryngeal nerve failed to restore motion of the glottis. Nevertheless, the procedures enabled adductory muscles to be reinnervated and then restored normal voice. Although nonsurgical treatment improved severe hoarseness, the vocal cord didn't restore normal functional motion of the vocal cord and normal voice. Conclusions Early and mid-stage recurrent laryngeal nerve decompression may restore normal motion of the vocal cord. End-to-end anastomosis of recurrent laryngeal nerve enables adductory muscles to be reinnervated and thus restores normal voice.

Objective To investigate laryngeal reinnervation for recurrent laryngeal nerve injury caused by thyroid surgery. Methods Included in this series were 42 patients with recurrent laryngeal nerve injury, undergoing nerve decompression in 8 cases, end-to-end anastomosis of recurrent laryngeal nerve in 6, anastomosis of main branch of ansa cervicalis to recurrent laryngeal nerve in 21, end-to-end anastomosis of recurrent laryngeal nerve in 6 cases, phrenic nerve graft combined with nerve muscular pedicle (NMP) technique or nerve decompression in 7. All cases were subjected to preoperative and postoperative videolaryngoscopy, voice recording, acoustic analysis and electromyography. Results In 5 patients with unilateral injury and with a course less than four months, nerve decompression restored functional adductory and abductory motion of the vocal cord. Although functional motion of vocal cord was still absent in two patients receiving nerve decompression with a course longer than 4 months and in one less than 4 months, and in all cases with unilateral vocal cord paralysis receiving ansa cervicalis anastomosis and end to end anastomosis of recurrent laryngeal nerve, these procedures did result in symmetric vibration of the vocal cords and physiological phonation. Good inspiratory abductent motion of the glottis was observed on the reinnervated sides by the phrenic nerves in 6 cases with bilateral vocal cord paralysis and the vocal cord excursion was from 3 to 5 mm. On the opposite reinnervated sides, 2 cases with nerve decompression restored functional adductory and abductory motion of the vocal cord; while 4 cases with NMP technique restored only slight abductent motion or no motion. These patients have achieved sufficient airway so that exercise to tolerance for daily activities is adequate without a tracheotomy. In no case was the voice weakened, no was there any problem with aspiration. Conclusions Nerve decompression seems to be the best procedure in laryngeal reinnervation; Main branch of ansa cervicalis technique achieves satisfactory reinnervation of adductor muscles; Phrenic nerve graft yields more satisfactory vocal cord abductory motion than NMP technique. Selection of the laryngeal reinnervation protocols should depend on the course, severity, type of nerve injury.

OBJECTIVE:
To explore the effective method to treat the glottic carcinoma invading the anterior commissure, we observed the difference of three kinds of operation to the anterior commissure of dogs by semiconductor laser.
METHOD:
Twelve dogs were divided into 3 groups at random, A: to cauterize to the thyroid cartilage's inner membrane of the anterior commissure, the right ventricular bands and vocal cord, the anterior and 1/3 of the left vocal cord; B: to cauterize part of the thyroid cartilage of the anterior commissure besides A; C: to open a window about 5 mm x 5 mm on the thyroid cartilage of the anterior commissure besides B. To take photos to observe the dogs' laryngeal wound with digital camera or electrolaryngoscope immediately, 1 week and 4 weeks, then to record the hoarseness, body weight and complications etc.
RESULT:
All the dogs' laser surgery were completed successfully. To observe the gross specimen, it was identical between the extent of excising and the design preoperation. One week later, the neonatal membrane covered the wound incomplete. Edematization, inflammatory reaction, pseudomembrane and the hoarseness were not heavy too. No obvious complication in group A. The neonatal membrane covered the wound incomplete. Edema, inflammatory reaction, pseudomembrane and granulation can be seen in group B. Exudation was heavy in local, erosion and infected, the hoarseness was severe. No other obvious complications in C. Different extent of adhesion could be seen at the anterior commissure in group A, B and C after 4 weeks, the laryngeal web formed, and the length of vocal cord was shorter than before. The color and luster of anterior commissure membrane was normal basically, the inflammatory reaction was not heavy in A and B groups. The anterior commissural membrane appeared the dark red chronic inflammatory reaction; the window was closed by neonatal membrane completely and had no infection in group C. To observe the gross specimen: the wound of anterior commissure was covered by prosthetic epithelia completely in three groups. The window was closed by complete membrane at the anterior commissure. The No. 1- 3 dog's conditions of hoarseness in three groups after 4 weeks: slight in A group, little severe in B and C group. The change of weight was not obvious at the pre or postoperative in group A and B. No obvious complication happened in each group postoperation.
CONCLUSION
The three operative methods have satisfied effects,the recovery of wound can cure well finally and no severe complications happened. It is valuable in clinic.
