OBJECTIVE: To evaluate the sustained efficacy of 2-year sublingual immunotherapy (SLIT) and 1 year after 2-year SLIT in children with allergic rhinitis (AR). METHOD: This study is a randomized, open and prospective trial. One hundred twenty children (between 4 and 11 years old) suffering from AR duo to mite were chosen from November, 2008 to June, 2009 in department of otolaryngology in our hospital divided into two groups: 60 underwent 2-year course of SLIT and one year follow-up combined with 3-year drug therapy as SLIT group; 60 received only drug therapy as control group. The patients were evaluated at three time points (baseline, end of SLIT and 1 year after SLIT discontinuation) regarding symptom scores including total nasal symptom score (TNSS), sneezing, rhinorrhoea, nasal obstruction, nasal itching and total medication scores (TMS) and adverse reaction. RESULT: (1) At the end of SLIT, the symptom scores excepting sneezing and total medication scores in SLIT group are obviously lower than those in control group (P < 0.01). At 1 year after SLIT discontinuation, all of the score including sneezing (P < 0.05) in SLIT group are lower than those of control group. (2) At the end of SLIT and 1 year after SLIT discontinuation, all of the scores are lower than those at baseline in SLIT group (P < 0.01); the scores were no different in SLIT group between the end of SLIT and 1 year after SLIT discontinuation (P > 0.05). But at the end of SLIT and 1 year after SLIT discontinuation, TMS was higher than it at baseline in control group (P < 0.01). At 1 year after SLIT discontinuation, nasal obstruction score was higher than it at baseline (P < 0.05). CONCLUSION SLIT can obviously improve the AR and the efficacy can sustain after 1-year SLIT discontinua tion. Drug increased in 3 years without SLIT.

Purpose To explore CT manifestations of thyroid carcinoma and its correlation with neck lymph node metastasis. Materials and Methods CT findings of 165 patients with thyroid carcinoma confirmed by surgical pathology were studied, including number, shape, size, calcium, necrosis, surrounding invasion and enhancement of substantial part, and its correlation with neck lymph node metastasis was also analyzed. Results 107 out of 165 patients (64.85%) suffered from neck lymph node metastasis. Different tumor number, calcium and necrosis were not associated with the rate of neck lymph node metastasis (χ2=0.009, 2.606, 1.522;P>0.05);tumor shape, size, surrounding invasion and enhancement were significantly different from the rate (χ2=26.510, 75.995, 68.922, 20.819;P<0.05). Patients age, tumor shape, size, enhancement and surrounding invasion were positively correlated with lymph node metastasis (r=0.124, 0.243, 0.276, 0.287, 0.395;P<0.05);the sequence of correlation was as follows:surrounding invasion>enh ancement>shape>size>age. However, patients gender, tumor number, calcium and necrosis showed on correlation (r=0.074, 0.126, 0.005, 0.121;P>0.05). Conclusion Lymph node metastasis is mainly associated with factors like age, tumor shape, size, enhancement and surrounding invasion. It is advisable that patients with high risk rate may consider selective cervical lymph node dissection.

[ ABSTRACT] AIM: To investigate the effects of bone marrow mesenchymal stem cells ( BMSCs) modified by programed death ligand-1 immunoglobulin ( PDL1 Ig) gene on immune rejection of orthotopic liver transplantation in rats. METHODS:Rat BMSCs were cultured and identified.The protein expression of PDL1 Ig in the BMSCs 72 h after infection with pAdEasy-1/PDL1 Ig was detected by Western blot.Mixed lymphocyte reaction was used to detect the inhibitory effect of BMSCs on the viability of T-lymphocytes in peripheral blood.The male Wistar rats were used as donors (n=40), and the male SD rats were used as recipients ( n=40 ) .The rat model of orthotopic liver transplantation was established by im-proved cuff method for observing acute rejection.The rats were randomly divided into control group, BMSCs treatment group, BMSCs/GFP treatment group and BMSCs/PDL1 Ig treatment group with 10 pairs each.Five rats were executed at the 7th day and the remains were used for measuring the survival time.RESULTS:The expression of PDL1 Ig in the BM-SCs was detected after pAdEasy-1/PDL1 Ig infection.The effect of BMSCs/PDL1 Ig on the viability of the lymphocytes was stronger than that of BMSCs/GFP.The level of IL-4 in BMSCs/PDL1 Ig group was significantly higher than that in the other 3 groups, while the levels of IFN-γand IL-2 were significantly decreased.The liver function in BMSCs/PDL1 Ig group was significantly improved and the levels of ALT, AST and TBil were almost recovered to normal at the 7th day after transplan-
tation.Severe rejection reaction was observed in control group, and rejection reactions were decreased with different degrees in BMSCs treatment group and BMSCs/GFP treatment group.Much slighter rejection reaction and significantly longer sur-vival time were showed in BMSCs/PDL1 Ig group than those in the other 3 groups.CONCLUSION:PDL1 Ig-modified BM-SCs inhibit the rejection of liver transplantation in rats and induce the immune tolerance, and the effect is better than that of BMSCs alone.

Objective No uniform standards has been established for the clinical diagnosis of schizophrenia .The article was to investigate the differentially expressed microRNA ( miRNA) profile and explore its clinical significance . Methods Differentially expressed miRNAs were screened by FlashTag TM Biotin RNA chips and SAM software in serum of patients with schizophrenia and healthy controls , then the validation was performed by real-time fluorescent quantitative reverse transcription polymerase chain reaction ( RT-PCR) . Results Three differentially expressed miRNAs were screened , including up-regulated hsa-miR-1281 ( fold change =1.50881) and two down-regulated miRNAs:hsa-miR-2861(fold change=0.642) and hsa-miR-638 (fold change=0.516).The com-parative analysis of RT-PCR by SPSS 17.0 Kruskal Wallis H Test validated the expression levels of hsa-miR-2861 and hsa-miR-638 in patients with schizophrenia decreased significantly in comparison to healthy controls (χ2 =4.089,χ2 =4.083, P<0.001).While the expression level of hsa-miR-1281 in patients with schizophrenia was in higher expression level compared with control group (χ2 =5.333, P<0.001). Conclusion There are differentially expressed miRNA profile in serum of patients with schizophrenia , in which miR-1281 , miR-2861 and miR-638 could be new serum markers for diagnosis of schizophrenia .

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.

OBJECTIVETo investigate the regularity of cervical lymph-node metastasis in oral squamous cell carcinoma patients and determine the treatment principle to cN0 patients.

METHODS1,024 oral squamous cell carcinoma cases who underwent neck dissection between 1980-2001 were investigated retrospectively.
