Objective:To study the changes of food characters in early swallowing recovery in patients with different laryngeal function preservation surgery.Methods:Collected patients with laryngeal cancer hypopharyngeal cancer who underwent laryngeal function preservation surgery in Lihuili Hospital of Ningbo Medical Center from January 2019 to March 2020. By fiberoptic endoscopic evaluation of swallowing (FEES) combined with Penetration and Aspiration Scale (PAS), prospectively observed the aspiration and invasion of solid, paste, fluid and other food in the early stage of trial feeding in patients with laryngeal hypopharyngeal cancer undergoing open laryngeal function preservation.Results:Among the 69 patients, 21 had vertical partial laryngectomy and 19 had partial pharyngeal partial laryngectomy. 15 days after the operation, 2 groups of patients after solid and paste food adaptability scored (1.14±0.36), (1.29±0.56) and (2.53±2.04), (2.84±2.31) points, Friedman Mtest for comparison difference had statistical significance ( Mvalues were 23.463 and 22.227, P<0.01); the liquid food for adaptability scored (2.10±1.09), (4.42±2.24) points, the pairwise comparison of liquid, solid and paste showed statistically significant differences ( tvalues were-0.976 to 1.105, P<0.05). The pairwise comparison of the adaptability of the two groups on 20 days after surgery showed no statistically significant difference ( P>0.05).Throat on the cricoid cartilage resection-ring hyoid epiglottis anastomosis (SLCP-CHEP) was 17 cases, laryngeal glottis level partial resection was 12 cases; postoperative 15 days the adaptability on the behavior of three kinds of food grade 2 groups of patients (4.65±1.90), (5.59±1.46), (6.53±1.13) points and (6.67±1.07), (4.50±2.07), (6.92±0.79) points, respectively; Minspection differences were statistically significant ( Mvalues were 29.525, 22.136, P<0.01).The pairwise comparison of solid and paste food in the two groups 20 days after the operation showed no statistically significant difference ( P>0.05), while the difference of liquid and paste was statistically significant ( tvalues were-1.375 to-0.853, P<0.05). Conclusion:In the early recovery of patients undergoing laryngeal function preservation surgery, the vertical group and the partial pharyngeal partial laryngectomy group has better adaptability to solid and paste food. The horizontal group has better adaptability to paste, the CHEP group has better adaptability to solid, and the four groups has the worst adaptability to convection, the recovery time of convective mass between the CHEP group and the horizontal group was longer. To understand the adaptability of patients with different surgical methods to food traits at the early stage of trial feeding can help to implement targeted rehabilitation programs, carry out progressive diet training, and reduce the complications of misinvasion, aspiration, aspiration pneumonia and other complications in the recovery cycle.

AIM:To explore the role of Bcl-2 and PCNA expression in the injury of rat myoblasts induced by hydrogen peroxide (H2O2).METHODS:Rat myoblasts at growth phase were divided into 4 groups based on basic fibroblast growth factor (bFGF) and H2O2 levels:normal control group, bFGF group, model group (H2O2 group) and treatment group (bFGF+H2O2 group).The expression of Bcl-2 and Bax was observed by immunohistochemistry and fluorescence methods.The protein levels of Bax, Bcl-2 and PCNA were determined by Western blot.RESULTS:Compared with model group, both immunofuorescence and fluorescence in treatment group showed enhanced Bcl-2 and low expression of Bax.Furthermore, the results of Western blot showed up-regulated PCNA and Bcl-2 protein and decreased Bax expression in treatment group.CONCLUSION:Oxidative stress results in the pathologic changes of myoblasts, and the up-regulation of Bcl-2 and PCNA may attenuate myoblast injury.

Objective To explore the diagnostic value of pink sign of iodine staining for early esophageal carcinoma. Methods Data of 312 lesions of 306 patients with suspected early esophageal carcinoma who received iodine staining from November 2015 to October 2017 were analyzed retrospectively. Lesions were divided into positive pink sign group and negative pink sign group according to the result of iodine staining. The relationship between pink sign and pathology were analyzed. Lesions recorded onset time of pink sign were divided into 4 groups by the onset time of pink sign, 0-30 s,>30-60 s,>60-90 s and>90-120 s, the diagnostic value of which was assessed with the receiver operating characteristic ( ROC) curve. Results Among the 312 lesions, 208 were identified positive pink sign, including 28 of inflammation or low-grade intraepithelial neoplasia ( LGIN ) , 180 of high-grade intraepithelial neoplasia ( HGIN ) or carcinoma, and 104 lesions were identified negative pink sign, including 69 of inflammation or LGIN, 35 of HGIN or carcinoma. The sensitivity, specificity and accuracy of positive pink sign in the diagnosis of HGIN and early esophageal carcinoma was 83. 7%, 71. 1% and 79. 8%, respectively. Multivariate analysis showed a significant association between the onset time of pink sign and histopathology ( P=0. 000, OR=0. 016, 95%CI=0. 042-0. 324) . The onset time of pink sign was recorded in 89 lesions in the positive group. The area under ROC curve of the onset time of pink sign was 0. 899, and the optimal cut-off value was 60 s, which indicated the good validity of the test with the sensitivity, specificity and accuracy of 92. 8%, 84. 2%and 91. 0%, respectively. Conclusion The pink sign of iodine staining for diagnosis of early esophageal carcinoma shows a high consistance rate, especially that appears within 60 s.

Objective:To evaluate the efficacy and safety of budesonide viscous suspension (BVS) in preventing extensive esophageal stenosis after endoscopic submucosal dissection(ESD).Methods:Data of 62 cases of early esophageal neoplasms or precancerous lesions receiving ESD whose postoperative mucosal defects were more than half the circumference of the esophageal lumen at Fujian Provincial Hospital from October 2014 to December 2018 were retrospectively studied. The patients were divided into the BVS group who received BVS therapy (n=24) and the control group who received no intervention (n=38). The incidence of postoperative stenosis, the number of bougie dilation procedures and complications were compared between the two groups. Risk factors for postoperative stricture were analyzed by logistic regression.Results:The incidence of postoperative stenosis [16.7% (4/24) VS 47.3% (18/38), P=0.005], the number of bougie dilation procedures (1.50±0.58 VS 2.70±1.09, P=0.039) in the BVS group were significantly lower than those in the control group. No serious adverse events such as perforation or massive hemorrhage related to BVS were observed in the BVS group. Multivariate logistic regression analysis showed circumferential extension ≥3/4 ( OR=37.970, 95% CI: 6.338-227.482) and non-intervention with BVS( OR=20.962, 95% CI: 3.374-130.243) were the independent risk factors for esophageal stricture after ESD. Conclusion:Administration of BVS is an effective and safe method to reduce the incidence of stenosis and the number of bougie dilation procedures for extensive esophageal stenosis after ESD.
