Neck dissection(ND)is one of the main treatment methods for oral and maxillofacial malignancies.Although ND type is in con-stant improvement,but intraoperative peal-pull-push injury of the accessory nerve,muscle,muscle membrane,fascia and ligament induced shoulder syndrome(SS)is still a common postoperative complication,combined with the influence of radiochemotherapy,not only can cause pain,stiffness,numbness,limited dysfunction of shoulder neck and arm,but also may have serious impact on patient's life quality and phys-ical and mental health.At present,there is still a lack of a systematic evaluation and rehabilitation management program for postoperative SS of oral and maxillofacial malignant tumors.Based on the previous clinical practice and the current available evidence,refer to the relevant lit-erature at home and abroad,the experts in the field of maxillofacial tumor surgery and rehabilitation were invited to discuss,modify and reach a consenusus on the etiology,assessment diagnosis,differential diagnosis,rehabilitation strategy and prevention of SS,in order to provide clinical reference.

Type I interferons play an important role in the pathogenesis of autoimmune diseases such as systemic lupus erythematosus(SLE).Monoclonal antibody shows therapeutic potential by blocking the signaling pathway.This study used recombinant human subunit 1 of the type I interferon receptor(IFNAR1)protein to immunize New Zealand white rabbits,and applied B cell cloning technology to screen and obtain rabbit parental antibodies.After humanization modification,QX006N was obtained.In vitro biological studies showed that QX006N could specifically bind to human IFNAR1 with an affinity of 108 pmol/L,and neutralize the type I interferon signaling pathway and this pathway mediated biological effects.This study provides a solid foundation for the development of antibody drugs targeting the type I interferon signaling pathway for the treatment of SLE.

Objective: To analyze the usage and influencing factors of quantified recipes in schools in the pilot areas of the Nutrition Improvement Program for Rural Compulsory Education Students (NIPRCES), and to provide references for student meal quality improvement. Methods: In 726 national pilot counties in 22 provinces where the NIPRCES was implemented, a total of 7 808 schools were included in the analysis as the survey objects in 2019. Data, including the usage of quantified recipes in schools and related factors, were collected through questionnaires. Multivariate Logistic regression was used to analyze the influencing factors of the schools use of quantified recipes. Results: Among the national pilot counties where the NIPRCES was implemented, 66.6 % of the monitored schools used quantified recipes, of which 69.7% of schools in the central region used quantified recipes, it was higher than that in the west region(65.2%) ( χ 2=15.13, P <0.01). Multivariate Logistic regression analysis showed that factors such as the schools in the central region, county based schools, the training frequency of canteen with 1-2 times per semester or once or more per month, regular training of nutrition knowledge, recipes provided by other departments, consideration of nutrition matching when formulating recipes, using catering software, providing local dietary allowances were positively correlated with the use of quantified recipes in schools( OR=1.31,0.72,1.44,1.73,1.75,3.20,2.15,2.72,1.17,P <0.05). Conclusion The proportion of using quantified recipes of schools in the NIPRCES area was relatively low, which might be affected by factors including the regional economic level, canteen training, and recipes sources. It is recommended to strengthen the construction of professional teams and canteen training. Schools need to be encouraged to use quantified recipes and promote school catering scientifically to improve healthy growth of students.

Objective: To analyze the status of parents sharing meal expenses in the national pilot areas of the Nutrition Improvement Program for Rural Compulsory Education Students (NIPRCES) and its influencing factors, so as to provide scientific data for promoting the proper implementation of the NIPRCES and the healthy development of students. Methods: In the 726 national pilot counties in 22 provinces where the NIPRCES was implemented, 8 109 primary and junior high schools were selected as the survey objects and included in the analysis according to the three feeding methods of canteen feeding, enterprise feeding and mixed feeding. Data such as the basic information of the schools and counties, and the status of parents sharing meal expenses were collected through questionnaires. Multivariate Logistic regression analysis was used to analyze the influencing factors of parents sharing meal expenses. Results: In the national pilot areas of the NIPRCES, schools where parents shared meal costs accounted for 30.2% of all monitored schools in 2019. In central and western areas, the proportion of schools where parents shared meal costs were 51.5% and 20.3%, respectively. In schools where parents shared meal costs, no matter in primary school or junior high school, the difference in the amount of meal expenses shared by parents of students in middle and western schools was statistically significant ( χ 2= 181.78 , 89.54, P <0.01). Among 38.7% of the parents of primary school students in the central region shared meal expenses of ≥2 yuan, and 47.5% of the parents of primary school students in the western region. Multivariate Logistic regression analysis showed that the parents of schools in the central region, junior high schools or nine year system schools, canteen feeding or other feeding, large school size, the nutritious meal subsidy used for lunch, middle and high family income level, medium and low input level of the monitoring counties, monitoring counties with other nutrition public welfare projects and insufficient working funds share a higher proportion of meal expenses ( OR=3.22, 1.51, 1.36, 1.74, 3.74, 1.38, 11.58, 2.40, 3.15, 1.50, 2.12, 3.36, 1.34, P < 0.05). Conclusion The proportion of meals shared by parents of school students in the NIPRCES implementation area was relatively low, which may be affected by factors such as economic level, feeding mode, school scale, etc.

Objective:To examine whether the combination of quantitative regional apparent diffusion coefficient (ADC) and amplitude-integrated electroencephalogram (aEEG) can predict the outcome of comatose patients with severe traumatic brain injury (sTBI).Methods:A prospective study was conducted. The patients with coma caused by sTBI [Glasgow coma scale (GCS) < 8] admitted to Suqian First Hospital from January 2016 to June 2019 were enrolled. All patients underwent aEEG examination and magnetic resonance imaging (MRI) scan within 1 week after emergency treatment. The ADC values of 9 regions of interest (frontal gray matter and white matter, parietal gray matter and white matter, temporal gray matter and white matter, caudate nucleus of basal ganglia, lenticular nucleus and thalamus) were measured by head MRI, and the mean ADC values of frontal lobe, parietal lobe, temporal lobe and basal ganglia were calculated respectively. According to the follow-up results after 12 months, the differences of each index between patients with poor prognosis [Glasgow outcome score (GOS) 1-2] and patients with good prognosis (GOS 3-5) were compared; the receiver operating characteristic curve (ROC curve) was drawn to evaluate the predictive ability of aEEG and ADC for the good prognosis of patients with sTBI, and the predictive value of the combination of aEEG and ADC.Results:A total of 52 patients with sTBI were enrolled, with mean age of (36.7±13.9) years old, 35 of whom were male. Within 12 months follow-up, 29 patients had achieved favorable outcomes and 23 patients had unfavorable outcome. There were 21, 17 and 14 patients with aEEG , and grade, respectively, and 19, 10 and 0 patients had good prognosis respectively. ADC values of 9 regions of interest in patients with good prognosis were significantly higher than those in patients with poor prognosis (×10 -6 mm 2/s: 924±107 vs. 531±87 in frontal gray matter, 804±95 vs. 481±74 in frontal white matter, 831±93 vs. 683±72 in temporal gray matter, 726±87 vs. 654±63 in temporal white matter, 767±79 vs. 690±75 in parietal gray matter, 716±84 vs. 642±62 in parietal white matter, 689±70 vs. 465±68 in caudate nucleus, 723±84 vs. 587±71 in lenticular nucleus, 807±79 vs. 497±67 in thalamus, all P < 0.01). ROC curve analysis showed that the area under ROC curve (AUC) of aEEG for predicting good prognosis of sTBI patients was 0.826, when the cut-off value of aEEG was < 1.5, the sensitivity was 94.7% and the specificity was 72.8%. Among the ADC value prediction abilities in the interested areas, the prediction of ADC value in frontal lobe and basal ganglia area were better than that in sTBI patients. AUC was 0.817 and 0.903 respectively. The best cut-off values were > 726×10 -6 mm 2/s and > 624×10 -6 mm 2/s respectively, the sensitivity of predicting prognosis were both 100%, and the specificity was 63.4% and 61.8%. A model combining frontal ADC and basal ganglia ADC with aEEG was 91.0% sensitive and 93.7% specific for favorable outcome of sTBI patients. Conclusion:Combination of the quantitative measurement of regional ADC and aEEG may be useful for predicting the outcome of the patients with sTBI.

Objective: : The function of B7H3, a member of the B7 family of proteins, in neuroblastoma (NB) remains poorly characterized. Here we examine the expression pattern of B7H3 in clinical NB specimens and characterize the phenotype of B7H3 knock-down in NB cell line. Methods: : Immunohistochemical (IHC) staining was carried out to assess the expression of B7H3 in clinical NB specimens. Survival association was analyzed using five Gene Expression Omnibus (GEO) datasets (GSE85047, GSE45480, GSE62564, GSE16476, GSE49710). Clonogenic survival and flow cytometry were performed after B7H3 knockdown to assess the cellular proliferation and cell survival in vitro. Impact of B7H3 silencing on NB growth was examined in vivo using the SH-SY5Y xenograft model. Results: : On IHC staining, B7H3 was widely expressed in clinical NB specimens. Analysis of the transcriptional profiles of five GEO datasets clinically annotated NB specimens revealed that decreased B7H3 expression was associated with improved overall survival. B7H3 knockdown suppressed the proliferation of the SH-SY5Y NB model in vitro and in vivo. Cell cycle analysis revealed that B7H3 silencing induced G1/S arrest. This arrest was associated with the suppression of E2F1 expression and induction of Rb expression. Conclusion : Our results demonstrate that B7H3 expression correlate with clinical survival in NB patients. Preliminary studies suggest that B7H3 may mediate the G1/S transition.

The fungal microbiota from self-retained soil and tongue coating of 18 patients with precancerous lesions of upper gastrointestinal (PLUG) were sequenced. The diversity of α, β in and the structure of the microbial community were analyzed, and the association of them was quantified by using the Spearman rank correlation method. The richness index (1.67±2.79) and the diversity index (0.25±0.10) of the fungal microbiota from tongue coating of PLUG patients were significantly lower than those from soil (4.00±4.69; 0.99±0.18) (all P values<0.001). The relative abundance of 11 taxa from tongue coating of these PLUG patients was positively associated with that from soil (all P values<0.05).

Objective To compare the sonographic features as well as clinical histopathological features of follicular variant papillary thyroid carcinoma(FVPTC) and conventional papillary thyroid carcinoma (CPTC) in pediatric patients.Methods From Jan.2006 to Dec.2017,26 FVPTC patients and 82 CPTC patients were enrolled in this study.The clinical histopathological findings and the sonographic features were compared between the two groups.FVPTCs and CPTCs were divided into PTC-like and follicular neoplasm(FN)-like based on sonographic characteristics.Results The mean nodule size of FVPTCs was larger than that of conventional PTCs.Extrathyroid invasion and cervical lymph node metastasis did not have significant difference between CPTC and FVPTC patients(53.8％ vs 62.2％ and 76.9％ vs 82.9％,respectively).Multiple nodules(P=0.000)and distant pulmonary metastases(P=0.024) were more frequent in CPTCs than in FVPTCs(P＜0.05).The rate of an ill-defined margin (P=0.000) and calcification (P=0.003)in terms of sonographic features were lower in FVPTCs than conventional PTCs(P＜0.05).A Ⅴ+Ⅵ diagnosis of PTC on FNAC of FVPTCs was less common than that of conventional PTCs (P=0.014).Multifocality(P=0.000),extrathyroidal invasion (P=0.000),and lymph node metastasis (P=0.000) were significantly different between PTC-like FVPTCs and FN-like FVPTCs.Conclusion FVPTC in children and adolescents shows a relatively larger size,more benign sonographic features,and a lower diagnostic rate of PTC by FNAC compared with conventional PTCs in pediatric patients.

Objective To assess cognitive impairment and its correlation with power of quantitative electroencephalogram (qEEG) in patients with temporal lobe epilepsy (TLE).Methods Fifty-five patients with TLE seen consecutively in Suqian First Hospital and 40 healthy controls (HC) were assessed by Mini-Mental State Examination (MMSE),Brief Cognitive Battery (BCB) and qEEG.The global interhemispheric and intrahemispheric difference values for power spectral ratios (Dv-PSR) were calculated.Cognitive functions and Dv-PSR of the TLE patients and the HC were compared,and correlation between cognitive impairment and power of qEEG was assessed using Spearman correlation analysis.The significance level was set at P≤0.05.Results Statistical analysis showed that MMSE scores did not have statistically significant difference between the TLE patients and the HC (26.9±2.4 vs 27.3±2.6,t=0.502,P=0.549).However,BCB examination showed that immediate memory,incidental memory,delayed recall,learning test,verbal fluency and recognition differed significantly between the TLE and the HC groups (7.34± 1.33 vs 8.92±1.37,6.05±1.12 vs 7.93±1.20,6.77±1.08 vs 8.19±1.14,11.87±4.47 vs 16.8±4.56,8.52±1.74 vs 9.75 ± 1.36,8.74 ± 1.19 vs 9.87 ± 1.18,respectively;t=2.916,Z=3.204,t=2.549,Z=3.937,t=1.341,t=2.791,P＜ 0.05).Interhemispheric Dv-PSR in frontal,central,temporal and parietal area was higher in the TLE group than in the HC group (0.478±0.043 vs 0.252±0.028,0.441±0.051 vs 0.306±0.039,0.394±0.027 vs 0.247± 0.018,0.511±0.036 vs 0.224±0.021,respectively;t=3.711,2.403,3.144,4.327,P＜0.05),and intrahemispheric Dv-PSR in frontal,central,parietal and occipital area (minus temporal area respectively) was also higher in the TLE group than in the HC group (0.521±0.024 vs 0.221±0.017,0.249±0.012 vs 0.167±0.008,0.187± 0.013 vs 0.104 ± 0.007,0.313 ± 0.021 vs 0.127 ± 0.009,respectively;t=4.208,3.192,2.611,3.737,P＜0.05).Spearman analysis showed positive correlations between intrahemispheric,interhemispheric Dv-PSR and several cognitive domains impairment assessed by BCB (P＜0.05).Conclusion There was mild cognitive impairment in TLE patients,which was significantly associated with Dv-PSR assessed by qEEG,suggesting that Dv-PSR measurement may be used as a marker for cognitive impairment in epilepsy.
