ABSTRACT
Objective:To investigate the effect of posterior nasal neurectomy(PNN) with pharyngeal neurectomy (PN) on chronic sinusitis with nasal polyps (CRSwNP)complicated with perennial allergic rhinitis (PAR). Methods:83 patients with perennial allergic rhinitis combined with chronic group-wide sinusitis with nasal polyps who attended our hospital from July 2020 to July 2021 were selected. All patients underwent conventional functional endoscopic sinusitis surgery(FESS)+ nasal polypectomy. Patients were divided according to whether they underwent PNN+PN. 38 cases in the experimental group underwent FESS combined with PNN+PN; 44 cases in the control group underwent conventional FESS alone. All patients underwent the VAS, RQLQ, and MLK before treatment, and at 6 months and 1 year after surgery. Meanwhile, other relevant data were collected and the preoperative and postoperative follow-up data were collected and analyzed to assess the differences between the two groups. Results:The total postoperative follow-up period was 1 year. The recurrence rate of nasal polyps at 1 year postoperatively and the nasal congestion VAS score at 6 months postoperatively were not statistically significant in the two groups(P>0.05). However, the patients in the experimental group had statistically significantly lower effusion and sneezing VAS scores, MLK endoscopy scores and RQLQ scores at 6 months and 1 year postoperatively, and nasal congestion VAS scores at 1 year postoperatively compared to the control group(P<0.05). Conclusion:For patients with perennial AR complicated with CRSwNP, the combination of the PNN+PN in FESS can significantly improve the short-term curative effect, and PNN+PN is a safe and effective surgical treatment.

Growth stimulating gene 2 (ST2) protein is a member of the interleukin-1 receptor family. It is mainly divided into a soluble secreted form sST2 and a transmembrane form ST2L. sST2 is a decoy receptor that competitively binds to interleukin-33 to block the interleukin-33/ST2L signaling pathway, worsening myocardial hypertrophy, fibrosis, and ventricular dysfunction. Measuring sST2 is of important value for diagnosis and/or prognosis evaluation of cardiovascular diseases. This paper mainly reviews the research progress in the relationship between cardiovascular diseases such as heart failure, coronary heart disease, hypertension, atrial fibrillation, myocarditis, cardiomyopathy, acute aortic dissection, and pulmonary hypertension, and sST2.

Among the indexes of PSG, there was no significant difference in AHI and LSaO2 values before and after operation, but AHI decreased and LSaO2 increased.@*Conclusion@#Nasal cavity ventilation expansion techniques can effectively alleviate the symptoms of nasal obstruction in OSAHS patients and improve their sleep and quality of life.
ABSTRACT
Objective@#To investigate the migration and invasion behaviors of Hep-2 after the targeted knockdown of yes-associated protein (YAP).@*Methods@#Hep-2 cells were knock-downed for YAP by shRNA as YAP-shRNA group, Hep-2 treated with non-specific shRNA as YAP-NC group, and Hep-2 with no treatment as control. Glucose uptake and lactate production in the cells were examined to assess Warburg effect. The migration and invasion behaviors of cells in three groups were observed. The expressions of vimentin and E-cadherin were detected by RT-PCR and Western Blot. The statistical software GraphPad Prism 7.0 was used to analyze significance of data. Two tailed Student′ s t-tests was used to determine significance when only two groups were compared. P values of less than 0.05 was considered statistically significant.@*Results@#Downregulation of YAP led to a obvious decrease in glucose uptake [(18.51±1.72)%] and lactate production [103.40±8.32] in Hep-2 cells compared with control [(41.20±1.11)% and 743.69±19.49, t=19.20 and 52.33, respectively, both P<0.01] and YAP-NC group [(39.60±0.78)% and 705.22±17.20, t=19.34 and 54.56, respectively, both P<0.01]. Compared with the control group (78.32±4.04) and YAP-NC group (77.28±3.11), the scratch healing ability of Hep-2 cells was significantly decreased in YAP-shRNA group (44.71±4.68). The P value was less than 0.01 (t=9.42 and 10.04). The number of cells with YAP-shRNA (33.30±4.19) passing through compartments was remarkable fewer than the control group (133.71±6.72) and YAP-NC group (126.32±4.21). The P value was less than 0.01 (t=21.96 and 27.13). The expression of E-cadherin protein in cells of YAP-shRNA group (6.16±0.11) was up-regulated compared with control (0.97±0.10, t=35.70, P<0.01) and YAP-NC group (1.13±0.09, t=36.28, P<0.01), while the expression of vimentin protein in cells of YAP-shRNA group (1.08±0.09) was down-regulated compared with control (5.67±0.12, t=29.91, P<0.01) and YAP-NC group (5.51±0.12, t=29.04, P<0.01).@*Conclusions@#The down-regulation of YAP in Hep-2 inhibits the migration and invasion of cells via suppressing Warburg and EMT program.

ABSTRACT
Objective@#To investigate the cause and urgent management of internal carotid artery injury during transnasal endoscopic skull base surgery.@*Methods@#Five cases of internal carotid artery injury encountered during transnasal endoscopic skull base surgery in Department of Otorhinolaryngology Head and Neck Surgery, the First Affiliated Hospital of University of Science of Technology of China, Anhui Provincial Hospital from December 2010 to July 2017 were analysed retrospectively. There were 2 cases of adenoid cystic carcinoma, 1 case of salivary gland-type adenocarcinoma, 1 case of petrous apex cholesterol granulomas and 1 case of squamous carcinoma. The cause of internal carotid artery injury and subsequent treatment were analysed, in order to prevent internal carotid artery injury during transnasal endoscopic surgery.@*Results@#Intraoperatively, all these 5 cases were packed with vaseline strip successfully. Two cases underwent subsequent intravascular covered stent graft implantation; 1 case underwent replacement of packing with muscle fascia graft; 1 case was packed with vaseline strip in nasal and nasopharyngeal cavity; 1 case accepted ligation of common carotid artery after failure of nasal packing. Four cases were successfully treated without craniocerebral or ocular complications. Otherwise, 1 case demonstrated with extremity paralysis after ligation. Follow up ranged from 6 to 84 months, no patient died.@*Conclusion@#The injury of internal carotid artery is related with improper operative procedures and anatomic localization, which should be treated properly with emergent hemostasis, and an experienced multidisciplinary team to repair vascular damage is very important.
ABSTRACT
OBJECTIVE To explore and evaluate the value of CT in diagnosis of malignant tumor of maxillary sinus and the accuracy of the involved bone wall by comparing the preoperative CT imaging with the pathologic examination.METHODS 11 patients without maxillary sinus squamous cell carcinoma and lymph node metastasis received pathological examination and enhanced CT scan before operation,partial or total maxillary resection were implemented according to the CT features and scope.The position and azimuth of the cut bone tissue samples were marked.The specimens were routinely fixed,decalcified,embedded,sliced and HE stained to observe the bone tissue pathological changes on the bone wall under light microscope.RESULTS Nasal sinus enhancement CT scan showed that the medial wall of maxillary sinus were all resorped and invaded(4 cases lack inner wall).Anterior wall was invaded in 6 cases,superior wall in 7 cases and bottom wall in 3 cases,posterior and exterior wall in 9 cases;After ruling out the cases without internal wall of maxillary sinus,the inner wall of the maxillary sinus was invaded by cancer cells,so was the front wall and the bottom wall.Those showed bone wall erosion on preoperative CT with continuous change but without interruption and accompanied by bone wall thickening and hardening were found without tumor invasion by postoperative pathological verification.CONCLUSION Bone wall damage on preoperative CT does not mean tumor invasion,and the probability of each maxillary sinus wall invasion is different;the comprehensive analysis found that for wormhole like change of bone wallon preoperative CT with continuous bone wall thickening and hardening of the 'reconstruction of bone destruction',there was no tumor invasion by postoperative pathological validation;Routine selection analysis of bone tissue pathology can supplement the extent diagnosis of malignant tumor of maxillary sinus on preoperative CT scan,so it can accurately estimate the T staging of tumor.It may provide a more effective basis for selection of minimally invasive surgery,postoperative evaluation of surgical effect and formulating more comprehensive treatment protocol.
ABSTRACT
Objective: To explore sarcoplasmic reticulum ryanodine receptor2 (RyR 2) expression and calcium releasing function in chronic heart failure (CHF) rabbits and to study the impact of long term valsartan treatment in relevant animals. Methods: HF model was established by volume overloading with pressure overloading in experimental rabbits. 27 rabbits were divided into 3 groups: Sham group, HF group and HF+valsartan group. n=9 in each group and the animals were treated for 7 weeks. Left ventricular structure, hemodynamic parameters, expression and functional changes of myocardiocyte sarcoplasmic reticulum RyR 2 were observed and compared among different groups. Results: Compared with Sham group, HF group had increased left ventricular mess index (LVMI), left ventricular end diastolic pressure (LVEDP) and decreased left ventricular shortening fraction, LVEF, all P<0.05. Compared with HF group, HF+valsartan group showed decreased LVMI, LVEDP and increased left ventricular shortening fraction, LVEF, all P<0.05. Sarcoplasmic reticulum RyR 2 expression and calcium releasing function were lower in HF group than Sham group, P<0.05; while they were both higher in HF+valsartan group than HF group, P<0.05. Conclusion: Long term application of valsartan could improve the cardiac function which might be related to increased myocardial sarcoplasmic reticulum RyR 2 expression and calcium releasing function in experimental CHF rabbits.
