Abstract
Objective: To investigate the endoscopic combined serological diagnosis strategy for G1 and G2 gastric neuroendocrine neoplasms (G-NENs), and to evaluate the safety, short-term, and long-term efficacy of two endoscopic treatment procedures: endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD). Methods: This study retrospectively analyzed the clinical data of 100 consecutive patients with G-NENs who were hospitalized at the Cancer Hospital of the Chinese Academy of Medical Sciences from January 2011 to October 2023. These patients underwent endoscopic treatment, and propensity score matching (PSM) was used to compare clinicopathological characteristics, as well as short-term and long-term efficacy of lesions in the EMR group and ESD group before and after treatment. Results: Among the 100 patients with G-NENs, the median age was 54 years old. Before surgery, 29 cases underwent endoscopic combined serological examination, and 24 of them (82.2%) had abnormally elevated plasma chromogranin A. The combined diagnostic strategy for autoimmune atrophic gastritis (AIG) achieved a diagnostic accuracy of 100%(22/22). A total of 235 G-NEN lesions were included, with 84 in the ESD group and 151 in the EMR group. The median size of the lesions in the ESD group (5.0 mm) was significantly larger than that in the EMR group (2.0 mm, P<0.001). Additionally, the ESD group had significantly more lesions with pathological grade G2[23.8%(20/84) vs. 1.3%(2/151), P<0.001], infiltration depth reaching the submucosal layer [78.6%(66/84) vs. 51.0%(77/151), P<0.001], and more T2 stage compared to the EMR group[15.5%(13/84) vs. 0.7%(1/151), P<0.001]. After PSM, 49 pairs of lesions were successfully matched between the two groups. Following PSM, there were no significant differences in the en bloc resection rate [100.0%(49/49) vs. 100.0%(49/49)], complete resection rate [93.9%(46/49) vs. 100.0%(49/49)], and complication rate [0(0/49) vs. 4.1%(2/49)] between the two groups. During the follow-up period, no recurrence or distant metastasis was observed in any of the lesions in both groups. Conclusions: The combination of endoscopy and serology diagnostic strategy has the potential to enhance the accuracy of diagnosing G1 and G2 stage G-NENs and their background mucosa. Endoscopic resection surgery (EMR, ESD) is a proven and safe treatment approach for G1 and G2 stage G-NENs.

Abstract
PirB is an inhibitory cell surface receptor particularly prominent on myeloid cells. PirB curtails the phenotypes of activated macrophages during inflammation or tumorigenesis, but its functions in macrophage homeostasis are obscure. To elucidate PirB-related functions in macrophages at steady-state, we generated and compared single-cell RNA-sequencing (scRNAseq) datasets obtained from myeloid cell subsets of wild type (WT) and PirB-deficient knockout (PirB KO) mice. To facilitate this analysis, we developed a novel approach to clustering parameter optimization called "Cluster Similarity Scoring and Distinction Index" (CaSSiDI). We demonstrate that CaSSiDI is an adaptable computational framework that facilitates tandem analysis of two scRNAseq datasets by optimizing clustering parameters. We further show that CaSSiDI offers more advantages than a standard Seurat analysis because it allows direct comparison of two or more independently clustered datasets, thereby alleviating the need for batch-correction while identifying the most similar and different clusters. Using CaSSiDI, we found that PirB is a novel regulator of Cebpb expression that controls the generation of Ly6Clo patrolling monocytes and the expansion properties of peritoneal macrophages. PirB's effect on Cebpb is tissue-specific since it was not observed in splenic red pulp macrophages (RPMs). However, CaSSiDI revealed a segregation of the WT RPM population into a CD68loIrf8+ "neuronal-primed" subset and an CD68hiFtl1+ "iron-loaded" subset. Our results establish the utility of CaSSiDI for single-cell assay analyses and the determination of optimal clustering parameters. Our application of CaSSiDI in this study has revealed previously unknown roles for PirB in myeloid cell populations. In particular, we have discovered homeostatic functions for PirB that are related to Cebpb expression in distinct macrophage subsets.

Abstract
Biallelic pathogenic variants in the USH2A gene result in Usher syndrome type Ⅱ and non-syndromic retinitis pigmentosa, both of which entail the progressive loss of photoreceptors leading to blindness. The cDNA of the USH2A gene is extensive, consisting of 15 606 base pairs, rendering it impractical for delivery via adeno-associated virus vectors for gene replacement therapy. Notably, exon 13 has emerged as a focal point for therapeutic intervention, given its predilection for harboring the most pathogenic variants within USH2A. Recent intervention studies targeting USH2A exon 13 through the utilization of antisense oligonucleotides, genome editing, and RNA editing approaches have exhibited promising therapeutic potential. This paper provides a comprehensive overview of the molecular mechanisms, outcome data, and the challenges associated with the application of these interventions in this domain.

Abstract
Objective: This study aimed to investigate the epidemiological characteristics of cardio-metabolic risk factors among children and adolescents aged 7-17 years in (Hebei, Zhejiang, Shaanxi, Hunan) 4 provinces of China and the influence of demographic and economic characteristics on them. Methods: A total of 1 747 children and adolescents aged 7-17 from a Community-based Cohort Study on Nervous System Disease in 2018 were selected. High waist circumference, central obesity, elevated TG, elevated TC, elevated LDL-C, decreased HDL-C, elevated blood pressure, elevated blood glucose, and clustering of risk factors was analyzed. χ2 test was used for univariate analysis, multivariate logistic regression was used to analyze the correlation between demographic and economic factors and risk factors, and the Cochran-Armitage trend test was used for trend analysis. Results: The detection rates of high waist circumference, decreased HDL-C, elevated blood pressure, elevated TG, elevated blood glucose, central obesity, elevated TC, and elevated LDL-C were 29.08%, 15.28%, 13.17%, 13.05%, 11.79%, 7.33%, 6.53%, and 5.15%, respectively. The rate of clustering of risk factors was 18.37%. Multivariate logistic regression analysis showed that the risk of high waist circumference in girls was higher than that in boys (OR=1.67, 95%CI: 1.26-2.22), and the risk of elevated blood glucose and clustering of risk factors was lower than that in boys (OR=0.69, 95%CI: 0.49-0.99; OR=0.72, 95%CI: 0.53-0.99). The risk of high waist circumference, decreased HDL-C, and clustering of risk factors in 13-17 years old group was higher than that in the 7-year-olds group (OR=2.24, 95%CI: 1.65-3.04; OR=1.59, 95%CI: 1.20-2.11; OR=1.75, 95%CI: 1.26-2.44), but the risk of central obesity was lower (OR=0.54, 95%CI: 0.37-0.78). The risk of elevated TC, elevated TG, and decreased HDL-C in children and adolescents in southern was higher than that in northern parts of China (OR=1.88, 95%CI: 1.25-2.83; OR=1.61, 95%CI: 1.17-2.22; OR=1.55, 95%CI: 1.19-2.04), but the risk of high waist circumference and central obesity was lower than that in northern China (OR=0.57, 95%CI: 0.43-0.75; OR=0.62, 95%CI: 0.42-0.90). The risk of decreased HDL-C in rural children and adolescents was higher than in urban children and adolescents (OR=1.36, 95%CI: 1.02-1.83). The risk of multiple risk factors increased with the increase in average monthly household income per capita and BMI level. Conclusions: High waist circumference, decreased HDL-C and elevated blood pressure were prominent cardio-metabolic risk factors among children and adolescents aged 7-17 years in 4 provinces of China in 2018. The region, average monthly household income per capita, and BMI were the main influencing factors of cardio-metabolic risk factors.

Abstract
Mutations in IDH1, IDH2, and TET2 are recurrently observed in myeloid neoplasms. IDH1 and IDH2 encode isocitrate dehydrogenase isoforms, which normally catalyze the conversion of isocitrate to α-ketoglutarate (α-KG). Oncogenic IDH1/2 mutations confer neomorphic activity, leading to the production of D-2-hydroxyglutarate (D-2-HG), a potent inhibitor of α-KG-dependent enzymes which include the TET methylcytosine dioxygenases. Given their mutual exclusivity in myeloid neoplasms, IDH1, IDH2, and TET2 mutations may converge on a common oncogenic mechanism. Contrary to this expectation, we observed that they have distinct, and even opposite, effects on hematopoietic stem and progenitor cells in genetically engineered mice. Epigenetic and single-cell transcriptomic analyses revealed that Idh2R172K and Tet2 loss-of-function have divergent consequences on the expression and activity of key hematopoietic and leukemogenic regulators. Notably, chromatin accessibility and transcriptional deregulation in Idh2R172K cells were partially disconnected from DNA methylation alterations. These results highlight unanticipated divergent effects of IDH1/2 and TET2 mutations, providing support for the optimization of genotype-specific therapies.

Abstract
Objective: To explore the effect of vestibular rehabilitation and to identify factors that can affect rehabilitation outcomes. Methods: From December 2018 to October 2020, patients who underwent vestibular rehabilitation in the Eye, Ear, Nose and Throat Hospital of Fudan University were prospectively followed up. A battery of vestibular function examinations and psychological status evaluations were applied before and after rehabilitation initiation. The main outcomes were vertigo/dizziness and unsteadiness, measured by visual analogue scale (VAS); Secondary outcomes were daily activities and participation, assessed by vestibular activities and participation measure (VAP). Paired t-test was used to compare the effects before and after rehabilitation. Binary logistic regressions were applied to analyze the influencing factors of rehabilitation outcomes. Results: A total sample of 171 patients was followed up regularly with a median time of 11 months. Of the 171 patients evaluated, 72 were males and 99 were females; age ranged from 10 to 89 years old with a median age of 55 years old. At 6-month follow-up, the difference of VAS score of vertigo/dizziness and unsteadiness pre-post rehabilitation was 1.79±1.80 and 1.56±1.76, respectively; The difference of activity and participation domain of VAP score was 2.51±13 and 1.27±3.75, respectively. All differences pre-post rehabilitation exhibited statistically significant with P values<0.01. Regression analysis demonstrated that the length of symptom onset was a significant predictor of poor balance recovery (OR=6.52; 95%CI:2.10, 20.27). Visual dependence (OR=5.44; 95%CI: 1.38, 21.47) and suspectable anxiety (OR=6.45; 95%CI: 1.49, 28.30) were identified as risk factors for poor recovery of vertigo/dizziness. Conclusions: Vestibular rehabilitation effectively reduces dizziness, promotes balance, and improves the function of daily activities. Time from the onset, visual dependence and suspectable anxiety are the main factors hindering a desirable rehabilitation outcome.

Abstract
Objective: Using propensity score matching method(PSM) to investigate the clinical effect of surgical plus radio(chemo)therapy and non-surgery chemoradiotherapy treatment strategies for advanced tonsillar squamous cell carcinoma. Methods: A retrospective analysis was conducted on the clinical data of 324 patients diagnosed with advanced tonsillar squamous cell carcinoma and treated in Peking Union Medical College Hospital from 2000 to 2018, confirmed by pathology and without distant metastasis. Survival analysis was performed using Kaplan-Meier estimates, the Cox proportional hazards model, and propensity score matching(PSM). Results: Of the 324 patients, 102 were treated with non-surgery chemoradiotherapy treatment strategies and 222 with surgical plus radio(chemo)therapy treatment. Cox multivariate analysis showed that the non-surgery treatment group had a favorable prognosis than the surgical treatment group, however, these outcomes were not significantly different [overall survival(OS): adjusted Hazard Ratios(aHR): 0.92, 95% confidence interval(CI): 0.60-1.42; disease-specific survival(DSS): aHR: 0.71, 95%CI: 0.43-1.20; disease-free survival(DFS): aHR: 0.82, 95%CI: 0.53-1.28]. The new patient cohort consisted of 102 subpairs after PSM. There were no significant differences between two groups(OS: aHR: 0.85, 95%CI: 0.51-1.40; DSS: aHR: 0.62, 95%CI: 0.35-1.11; DFS: aHR: 0.80, 95%CI: 0.49-1.33). Conclusion: Our findings indicate that patients with non-surgical treatment do not have significantly better survival outcomes compared to surgical treatment group, while non-surgical treatment has advantages in improving the quality of life of patients, so comprehensive treatment based on radiotherapy and chemotherapy may be recommended for advanced tonsillar squamous cell carcinoma.

Abstract
Objective: To analyze the epidemiological characteristics of a local outbreak of COVID-19 caused by SARS-CoV-2 B.1.617.2(Delta) variant in Liwan district, Guangzhou, and provide evidence for the further prevention and control of the Delta variant of COVID-19. Methods: From May 21 to June 18, 2021, the incidence data of COVID-19 caused by Delta variant were obtained from National Notifiable Disease Report System of Chinese Disease Prevention and Control Information System and Liwan District Center for Disease Control and Prevention of Guangzhou.Frequency analysis (proportions), histograms, and percentage stacked area plots were used to describe the epidemiological characteristics of the outbreaks. The incubation period and time-varying reproduction numbers (Rt) estimations were used for the further analysis. Results: By June 18, 2021, a total of 127 COVID-19 cases caused by Delta variant was reported in Liwan district. The youngest case was aged 2 years and the oldest was aged 85 years. There were 18.9% (24/127) aged <18 years, 43.3% (55/127) aged 18-59 years, and 37.8% (48/127) aged ≥60 years, the male to female ratio of the cases was 1∶1.35 (54∶73). The cases were mainly retired people (32.3%, 41/127), the jobless or unemployed (18.1%, 23/127), and students (16.5%, 21/127). The infections mainly occurred in Baihedong (70.1%, 89/127) and Zhongnan street (23.6%, 30/127) communities in the southern area of Liwan district. The median incubation period of the Delta variant infection was 6 days (range: 1-15 days). The clinical classification were mainly common type (64.6%, 82/127). The basic reproduction number (R0) was 5.1, Rt which once increased to 7.3. The transmissions mainly occurred in confined spaces, such as home (26.8%), restaurant (29.1%), neighborhood (3.9%), and market (3.1%), the household clustering was predominant. Close contacts tracing (66.1%) and community screening (33.1%) were the main ways to find the infections. Conclusion: The COVID-19 outbreak caused by Delta variant in Liwan district of Guangzhou was highly contagious, with the obvious characteristics of household clustering and high proportions of cases in adults aged 18-59 years and elderly people aged ≥60 years.

Abstract
In order to sustain proficient life-long hematopoiesis, hematopoietic stem cells (HSCs) must possess robust mechanisms to preserve their quiescence and genome integrity. DNA-damaging stress can perturb HSC homeostasis by affecting their survival, self-renewal, and differentiation. Ablation of the kinase ataxia telangiectasia mutated (ATM), a master regulator of the DNA damage response, impairs HSC fitness. Paradoxically, we show here that loss of a single allele of Atm enhances HSC functionality in mice. To explain this observation, we explored a possible link between ATM and the tumor suppressor phosphatase and tensin homolog (PTEN), which also regulates HSC function. We generated and analyzed a knockin mouse line (PtenS398A/S398A), in which PTEN cannot be phosphorylated by ATM. Similar to Atm+/-, PtenS398A/S398A HSCs have enhanced hematopoietic reconstitution ability, accompanied by resistance to apoptosis induced by genotoxic stress. Single-cell transcriptomic analyses and functional assays revealed that dormant PtenS398A/S398A HSCs aberrantly tolerate elevated mitochondrial activity and the accumulation of reactive oxygen species, which are normally associated with HSC priming for self-renewal or differentiation. Our results unveil a molecular connection between ATM and PTEN, which couples the response to genotoxic stress and dormancy in HSCs.

Abstract
Objective: To explore the clinical characteristics and risk factors of pediatric patients with Wiskott-Aldrich syndrome (WAS). Methods: This was a case-control study. Clinical data of 165 cases of pediatric patients with WAS, who visited the Department of Rheumatology, Children's Hospital of Chongqing Medical University between January 2007 and August 2020 were retrospectively analyzed and divided into death group and survival group (control group) according to the prognosis in the follow-up. Two independent samples t-test, Welch approximate t-test, Mann-Whitney U test, Pearson χ² test, Yates corrected χ² test, or Fisher exact probability test were used for comparison between groups. Risk factors were analyzed by multivariate Logistic regression analysis. Results: A total of 165 patients with Wiskott-Aldrich syndrome were enrolled in this study, including 40 cases in the death group and 125 cases in the survival group. The WAS score was (4.1±0.8) score in the death group and (3.1±1.2) score in the survival group. The age was 19 (9, 28) months in the death group and 60 (36,86) in the survival group. The episode rates of recurrent infection and (or) severe infection, intracranial hemorrhage and eczema in the death group were significantly higher than those in the survival group (95.0% (38/40) vs.32.0% (40/125),25.0% (10/40) vs. 2.4% (3/125), 90.0% (36/40) vs. 72.0% (90/125), χ²=48.253, 18.325, 5.440, all P<0.05). Infection (22 cases, 55.0%) and intracerebral hemorrhage (15 cases, 37.5%) were the main causes of death, 3 cases (7.5%) died of severe graft-versus-host disease after transplantation. The Logistic regression model indicated that repeated infection and (or) severe infection and non-use of intravenous immunoglobulin (IVIG) replacement therapy were risk factors for death in Chinese WAS patients (OR values were 8.999 and 2.860, 95% CI were (2.041-39.667) and (1.375-5.950), respectively, all P<0.05). Conclusions: Recurrent and (or) severe infection is the main risk factor of death for WAS patietns. Regular IVIG treatment can improve the survival rate of patients with WAS.

Abstract
AIMS The short-term effects of different organic manure nitrogen (N) input on soil ammonia-oxidizing archaea (AOA) and bacterial (AOB) activity and community structure at maturity stages of early rice and late rice were investigated in the present paper, in a double-cropping rice system in southern China. METHODS AND RESULTS A field experiment was done by applying five different organic and inorganic N input treatments: (i) 100% N of chemical fertilizer (M0), (ii) 30% N of organic manure and 70% N of chemical fertilizer (M30), (iii) 50% N of organic manure and 50% N of chemical fertilizer (M50), (iv) 100% N of organic manure (M100) and (v) without N fertilizer input as control (CK). Microbial community changes were assessed using fatty acid methyl esters, and ammonia oxidizer (AO) changes were followed using quantitative PCR. The results showed that AOA were higher than that of AOB based upon amoA gene copy at maturity stages of early rice and late rice. Also, the abundance of AOB and AOA with M30, M50 and M100 treatments was significantly higher than that of CK treatment. Manure N input treatments had significant effect on AOB and AOA abundance, and a higher correlation between AOB and manure N input was observed. AOB correlated moderately with soil organic carbon content, and AOA correlated moderately with water-filled pore space. CONCLUSIONS This study found that abundance of AOB and AOA was increased under the given organic N conditions, and the soil AOB and AOA community and diversity were changed by different short-term organic manure N input treatments. SIGNIFICANCE AND IMPACT OF THE STUDY Soil microbial community and specific N-utilizing microbial groups were affected by organic manure N input practices.

Objective: Based on the application and funding of Otorhinolaryngology Head and Neck Surgery (H13) funded by the Nature Science Foundation of China (NSFC), we analyzed the basic research status of the field of Otorhinolaryngology Head and Neck Surgery, and provided the references for developing the discipline development plan, optimizing the discipline strategic layout and promoting the discipline progress. Method: The data of both applied and funded grants of Otorhinolaryngology Head and Neck Surgery in NSFC from 2009 to 2019 were collected for further analysis. Results: From 2009 to 2019, H13 received 5 103 applications, accounting for 1.00% of the total number of applications in the department of health science, and 922 applications were funded (mainly from the General Projects and the Youth Science Fund Projects), with a funding rate of 18.07% and a funding amount of 445.509 million yuan, accounting for 1.02% of the total funding amount of the department of health science. Among the seven sub-categories of H13, H1304 (Hearing abnormal and balance disorders) received 1 845 applications, and 352 were funded. H1301 (Disease of smell, nose and anterior skull base) received 1 217 applications, and 248 were founded, H1303 (Ear and lateral skull base disease) and H1305 (Otorhinolaryngology and developmental related diseases) received 498 and 488 applications,and 83 and 112 were founded respectively. The National Science Fund for Distinguished Young Scholars received 33 applications, and 5 were founded, with a funding rate of 15.15%. Clinicians accounted for 81% of the General Projects principals, and researchers and technicians accounted for 19%. Clinicians accounted for 72% of the Youth Science Fund Projects principals, and researchers and technicians accounted for 24%. Conclusion: The basic research of Otorhinolaryngology Head and Neck Surgery in China has some shortcomings, such as small volume, uneven development of various disciplines, less leading academic leaders, less training of young leading talents, less major projects, more clinicians instead of researchers engaged in the basic scientific research.

Abstract
Objective: To explore the change of hypothalamic-pituitary-thyroid axis hormones and it's role in depression in obstructive sleep apnea-hypopnea syndrome. Methods: Seventy-three male OSAHS patients [age (39±11) years] and 13 male controls [age (36±7.5) years] were enrolled from August 2013 to May 2017 in the 1(st) Hospital of China Medical University. Overnight polysomnography and depression were assessed. The serum TRH, TSH, FT4 and FT3 levels were measured on the next morning. The relationship between depression and hypothalamic-pituitary-thyroid axis was analyzed. Results: Compared with the control group, severe hypoxia group had higher serum FT3 level [(4.5±0.6) ng/L vs. (5.4±0.7)ng/L, P<0.05)] and depression score (30±7 vs. 40±10, P<0.05). Further analysis revealed that serum FT3 level (5.0±0.5 ng/L vs. 5.5±0.7ng/L, P<0.05) and FT4 level [(16.2±1.9) ng/L vs. (18.2±2.3) ng/L, P<0.05] were lower in the patients with depression than those without. Conclusion: The decrease of serum FT3 and FT4 levels in OSAHS patients with severe hypoxia was closely related to the occurrence of depression.

Abstract
Objective: To investigate the effects of chronic intermittent hypoxia on somatotropic axis hormone levels in rats. Methods: Mature male Wistar rats were exposed to air or intermittent hypoxia randomly.The serum levels of growth hormone-releasing hormone (GHRH), growth hormone (GH) and somatostatin (SS) were measured before exposure, at the 4th, 8th, and 12th week after exposure. Different hormone levels in two groups were compared and analyzed. Results: Compared with the control group, GHRH levels in chronic intermittent hypoxic group showed a significant decline at the 4th week [(732.77±46.99)pg/ml vs. (893.59±40.00) pg/ml, P<0.05], while SS levels at the 8th week [(30.71±2.27) pg/ml vs. (44.69±3.36) pg/ml, P<0.05] and GH levels at the 12th week [(1.20±0.29) ng/ml vs. (2.06±0.13) ng/ml, P<0.05] were similarly reduced. As the duration of intermittent hypoxia was prolonged, the GHRH levels did not decrease further [4th week (732.77±46.99) pg/ml vs. 8th week (607.54±131.61) pg/ml vs. 12th week (730.05±40.63) pg/ml, P>0.05].However, the serum SS levels decreased further from the 8th week to the 12th week [(30.71±2.27) pg/ml vs. (24.41±4.06) pg/ml, P<0.05]. Conclusion: Chronic intermittent hypoxia might inhibit the function of somatotropic axis. Hypothalamic hormones are the earlyonesto be influenced, thereafter the entire axis.

Abstract
OBJECTIVE To explore the association between SPRY gene family and the risk of non-syndromic oral clefts among Chinese populations, in respect of single nucleotide polymorphisms (SNPs) association and parent-of-origin effects. METHODS Based on case-parent design, this study used the data of SPRY gene family in a next generation sequencing study of 183 non-syndromic cleft lip with or without cleft palate (NSCL/P) case-parent trios (549 participants) recruited from 2016 to 2018, to analyze the effects of SNP association and parent-of-origin. The sequencing study adopted a two-stage design. In the first stage, whole exome sequencing was conducted among 24 NSCL/P trios with family history to explore potential signals. Then in the second stage, another 159 NSCL/P trios were used as validation samples to verify the signals found in the first stage. The data of general information, disease features and parental environmental exposures for participants were collected through questionnaires. Blood samples were collected from each participant for DNA extraction and sequencing. Transmission disequilibrium tests (TDT) were conducted to test for the association between SNPs and NSCL/P, while Z score tests were applied to analyze parent-of-origin effects. The analyses were performed using Plink (v1.07). TRIO package in R (v3.5.1). Besides, famSKAT analyses were conducted in the first stage to combine the effect of SNPs located on the same gene, using famSKAT package in R(V3.5.1). Bonferroni method was adopted to correct multiple tests in the second stage. RESULTS Twenty-two SNPs in SPRY gene family were included for analyses after the quality control process in the first stage. Based on the variants annotation, functional prediction and statistical analysis, rs1298215244 (SPRY1) and rs504122 (SPRY2) were included in the second verification stage. TDTs in the verification stage revealed that rs1298215244: T>C, rs504122: G>C and rs504122: G>T were associated with the risk of NSCL/P after Bonferroni corrections, where rs504122: G>T was a rare variation. Although the test for parent-of-origin effect of rs1298215244: T>C reached nominal significance level, no SNP showed significant association with NSCL/P through parent-of-origin effect after Bonferroni corrections. CONCLUSION This study found that SNPs (including both common and rare variants) among the SPRY gene family were associated with the risk of NSCL/P among Chinese populations. This study failed to detect parent-of-origin effects among the SPRY gene family.

Abstract
Objective: Non-syndromic cleft lip with or without cleft palate (NSCL/P) is a common birth defect with its genetic evidence widely explored. This study explored the potential the parent-of-origin (PoO) effect of WNT pathway on the risks of NSCL/P, using a case-parent trio design. Methods: Data on the single nucleotide polymorphism (SNP) of WNT genes were selected from a genome-wide association study (GWAS). A total of 806 Chinese non-syndromic cleft lip patients, with or without cleft palate (NSCL/P) case-parent trios, were gathered from an international consortium. PoO effect of WNT pathway genes and its haplotypes were explored by log-linear models. Additional Wald tests were performed to assess: a) the heterogeneity of PoO effect between different maternal exposures, b) the interaction between PoO effect, c) maternal exposure to environmental tobacco smoke (ETS), and d) multivitamin supplementation during pregnancy. The threshold for statistical significance was adjusted as 3.47×10(-4), according to Bonferroni correction. Results: After quality control, a total of 144 SNPs within seven genes were included for analyses, among which 8 SNPs were of potential PoO effect (P<0.05). However, none of them achieved the statistical significance after Bonferroni correction. The haplotype rs4074668-rs12725747 (T-A) on WNT9A showed significant PoO effect, based on the haplotype test for PoO (P=2.74×10(-4)). In addition, no statistically significant interaction was found in further exploration of this haplotype under environmental exposures as ETS or multivitamin supplementation. Conclusions: Genes in the WNT pathway may influence the NSCL/P risks through the potential PoO effect. Particularly, the haplotype rs4074668-rs12725747 (T-A) on WNT9A presented significant PoO effect on NSCL/P, statistically. From this current study, findings on WNT pathway related risks among the NSCL/P, need to be further validated by independent samples in the future.

Abstract
e15610 Background: Sorafenib, which was the only choice of systemic therapy in the past ten years in HCC. But sorafenib alone achieves limited efficacy. Reversing sorafenib resistance was difficulty for oncologist. Based on previous study, we investigated whether NT157 augmented antitumor activity of sorafenib and underlying mechanisms. Methods: HCC cell lines and xenografts were employed to determine antitumor activity of NT157 combined with sorafenib and explore underlying mechanisms. Results: NT157 inhibited proliferation and induced apoptosis in dose and time dependent manner in HCC cells. HCC tumor was efficiently inhibited by NT157 in vivo. Mechanistic investigations elucidated NT157 induced phosphorylation of IRS1 by ERK pathway, and blockade of Stat3 pathway was independent of ERK pathways. NT157-activated p-ERK committed them to degradation by proteasome. CCL20 and CXCL8 were selected as efficacy markers by sequence, which effectively and minimal invasively predict efficacy. No major toxicity of liver, kidney and hemogram was observed, but SII (systemic immune-inflammation = N*P/L) was much lower, implying NT157 may influence immune and inflammatory reaction. Combination of NT157 and sorafenib increased percentage of apoptotic cells, c-caspase3 and PARP. Besides, sorafenib can reverse transient elevation of p-ERK by NT157, which may be potential mechanism of two drugs performing synergy. In vivo tumor volume and weight decreased in combination group compared with monotherapy. NT157 decreased p-AKT, which was overexpressed in resistant cell, implying NT157 may reverse sorafenib resistance by inhibiting AKT. To explore mechanism of sorafenib resistance in HCC, we established sorafenib-resistant HCC cell. Combination of two drugs inhibited cell viability, increased the percentage of apoptotic cells and activated of caspase3 and PARP cleavage in resistant cell. Conclusions: Our findings demonstrate NT157 displays potent antitumor effect in HCC via blockade IRS1 and STAT3 pathways. Combination of NT157 and sorafenib has potential therapeutic effect, even in sorafenib-resistant HCC cell. These findings identify a novel therapeutic strategy for HCC using a combination of NT157 and sorafenib.

Abstract
Objective: To compare the difference of preoperative planning parameters between 3D-printing non-coplanar template (3D-PNCT) and 3D-printing coplanar template (3D-PCT) in the treatment of pelvic wall recurrent gynecological malignant tumor with radioactive seeds implantation, and to guide the clinical application. Methods: From January 2016 to March 2018, 33 patients with pelvic wall recurrent gynecological malignant tumor were treated with radioactive seeds implantation assisted by 3D-printing template and in Peking University Third Hospital. All patients underwent 3D-PNCT and 3D-PCT preoperative planning. The D(90) of target remained similar for the same patient. The parameters were compared with Wilcoxon test or Kruskal-Wallis test. Results: D(90) was similar between the two groups (P>0.05). The number of inserting needles through intestine and bone in 3D-PNCT group was less than that in 3D-PCT group (0 (0-13), 0 (0-25), Z=-2.941, P<0.05;0 (0-3), 0 (0-25), Z=-2.232, P<0.05). Conclusion: For patients with gynecological malignancies with pelvic recurrence, both of the two peroperative plans could achieve prescription dose, but 3D-PNCT is more safer.

Abstract
Objective: To describe the study design, the characteristics of participants as well as the pedigrees included in the baseline survey of Fujian Tulou Family Cohort Study. Methods: Fujian Tulou Family Cohort Study was a prospective open cohort study with a biological sample bank. A baseline survey was conducted in Tulou areas of Nanjing county in Fujian province from 2015 to 2018, including questionnaire survey, physical and biochemical indicators examinations, and blood sample collection in adults aged ≥18 years. In addition, family relationship of the participants was also recorded. The pedigree information of the juveniles under 18 years old were also collected. Results: The baseline survey included 2 727 individuals in two clans, of whom 2 373 (87.0%) were adults, and 2 126 participants completed questionnaires, physical examinations and biochemical tests. The average age of the 2 126 participants was (57.9±13.3) years, with 39.4% being males. The current smoking rates in male and female participants were 41.2% and 2.1%, respectively. The corresponding rates of current alcohol consumption were 19.0% and 2.6%. For common chronic diseases, the prevalence rates were 51.3% for hypertension, 9.7% for diabetes and 26.7% for hyperlipemia according to the self-reported disease diagnoses, health examination results and biochemical examination results in class Ⅱ or Ⅲ hospitals. Based on the family relationship information and genealogical data, 710 pedigrees were finally identified, consisting of 5 087 family members. The numbers of five, four, three, and two generations pedigrees were 3, 88, 238 and 381, respectively. The pairs of the first to the fifth degree relatives were 12 039, 2 662, 1 511, 202 and 31, respectively. Conclusion: The establishment of Fujian Tulou Family Cohort provides valuable resources for exploring the genetic risk factors, environmental risk factors and gene-environment interactions contributing to the risk of common chronic diseases.

Abstract
Objective:Pharyngeal stenosis as a postoperative complication following pharyngeal surgery (tonsillectomy/adenoidectomy) with coblation is rare and may be difficult to treat. This report is to explore the causes of pharyngeal stenosis and presents our successful treatment experience. Method:From Jan 2012 to July 2016, 5 children with pharyngeal stenosis (2 nasopharyngeal stenosis and 3 nasopharyngeal stenosis combined with oropharyngeal stenosis) secondary to pharyngeal surgery (tonsillectomy/adenoidectomy) in Peking Union Medical College Hospital were analyzed. Five cases with severe nasopharyngeal stenosis received surgery of scar resection, horizontal-to-vertical pharyngoplasty and local pharyngeal flap rotation; and three of them received free skin transplantation. After stenosis repair surgery, prolonged nasopharyngeal hollow stents were used for more than 6 months. To evaluate the therapeutic effect, pharyngeal cavities and symptoms of difficulty nasal breathing, mouth breathing, difficulty in blowing nose, hyponasal speech, snoring, restless sleep, anosmia, dysphagia were assessed and compared before and after surgery. Result:With 7-46 months follow-up, all symptoms of the 5 cases are ameliorated and the diameters of nasopharyx are more than 1.5 cm. No velopharyngeal insufficiency complication happened. Conclusion:Improper operation with coblation can cause severe pharyngeal stenosis. Flap rotation, horizontal-to-vertical pharyngoplasty and prolonged use nasopharyngeal hollow stents are reliable methods to correct pharyngeal stenosis following children's pharyngeal surgery.

Abstract
Objective: To investigate the effect of GHRH on the cognitive function of OSAHS patients by detecting the serum GHRH levels and assessing their cognitive function in patients with OSAHS. Methods: A total of 70 moderate-severe OSAHS patientsand 32 adults with snoring from October 2013 to May 2017 were enrolled for overnight polysomnography(PSG) and cognitive function assessment. Blood samples were taken at the next morning and serum GHRH levels were measured by ELISA. Results: There was no significant difference between OSAHS group (318.73±186.66)pg/ml and control group (291.48±147.36)pg/ml. Compared with control group, the serum GHRH levels were significantly increased in OSAHS patients without cognitive impairment (370.31±197.33)pg/ml, and evidently decreased in those with cognitive impairment (193.63±70.97)pg/ml (both P<0.05). The cognitive function of OSAHS patients was influenced by serum GHRH levels (OR=0.42, 95%CI: 0.24-0.73), body mass index (OR=2.23, 95%CI: 1.03-4.79), and daily sleepiness score (OR=1.80, 95%CI: 1.04-3.09). Conclusion: Serum GHRH levels in patients with moderate-severe OSAHS may play a protective role in patients' cognitive function.

Abstract
Objective: To evaluate the relationship of dosimetry parameters and efficacy of (125)I seeds implantation for pelvic recurrent cervical cancer (PRCC) after external beam radiotherapy(EBRT) under CT guidance. Methods: A retrospective analysis was made on 30 PRCC patients after EBRT in Peking University Third Hospital with (125)I seeds implantation under CT guidance. Postoperative plans were made to evaluate the dosimetric parameters. Kaplan-Meier method was used to calculate local progression free survival (LPFS) rate and overall survival (OS) rate, and Log-rank test and Cox regression were used for univariate and multivariate analysis. Results: The 1-year and 2-year LPFS rate was 39.4% and 22.5%, respectively. The 1-year and 2-year OS rate was 57.3% and 27.4%, respectively. On postoperative plan, D(90) was (132±47) Gy, D(100) was (51±24) Gy, V(100) was 88%±10%, V(150)was 69%±15%, V(200) was 51%±18%.LPFS time would be longer while D(90) ≥105 Gy or D(100) ≥ 55 Gy or V(100) ≥ 91% (all P<0.05). D(100) was significantly related to LPFS (P<0.05). But these dosimetry parameters got no effect on OS. Conclusions: LPFS time of (125)I seeds implantation for PRCC after EBRT under CT guidance would be longer when D(90)≥105 Gy or D(100)≥ 55 Gy, or V(100)≥ 91%. D(100) is an independent factor related to LPFS.

Abstract
Objective: To summarize the clinical characteristics of congenital pyriform fistula with acute suppurative thyroiditis as the initial presentation. Method: A total of 71 patients with congenital pyriform sinus fistula were treated, of which 33 cases had acute suppurative thyroiditis as the first symptom. For the patients with congenital pyriform sinus fistula who have acute suppurative thyroiditis as the first symptom, infection should be controlled first. Full drainage should be done when necessary, and the lesion should be completely excised during the stable period. Result: All the patients were followed up for 6 months to 216 months. No recurrence was found during follow-up. Conclusion: For patients with acute suppurative thyroiditis, the possibility of congenital pyriform sinus fistula should be considered.If the diagnosis of congenital pyriform sinus fistula is clear,the lesion should be completely resected by surgery. .

Abstract
Objective: To investigate the etiology, clinical and pathological characteristics of laryngeal leukoplakia and the predictive risk factors of recurrence and malignant transformation. Methods: Clinical data of 263 patients with laryngeal leukoplakia between January 2000 and December 2015 were analyzed retrospectively. Results: The pathological diagnoses included squamous epithelial hyperplasia (54.4%), mild dysplasia (17.9%), moderate dysplasia (12.2%), severe dysplasia and carcinoma in situ (12.5%), and invasive carcinoma (3.0%). Age and the extent of lesion were statistically different among different pathological groups (P<0.05). Gender, smoking and alcohol consumption did not show statistical differences among different pathological groups (P>0.05). Follow-up of 215 patients, excluding 6 cases of invasive carcinoma. The recurrence rate was 20.6%(43/209), and the malignant transformation rate was 5.3%(11/209). Multivariate analysis showed that pathological classification of moderate to severe dysplasia was the independent risk factor for recurrence and malignant transformation of laryngeal leukoplakia (P<0.05). In patients with severe dysplasia and carcinoma in situ, the recurrence proportion of conservative treatment, vocal cords (partial) resection and radiotherapy were 8/10, 0/10 and 2/11 respectively. Conclusions: Laryngeal leukoplakia occurs frequently in elderly men with long-term smoking history. Pathological diagnoses are different. The grade of dysplasia is the predictive risk factor for the recurrence and malignant transformation of laryngeal leukoplakia. More aggressive treatment and closer follow-up should be warranted for patients with moderate dysplasia, severe dysplasia and carcinoma in situ.

Abstract
Objective:To investigate the expression of LINC00261 in laryngeal carcinoma and to discuss their relevance and the roles in carcinogenesis and development of laryngeal carcinoma. Method:The expressions of LINC00261 in laryngeal carcinoma tissue and paired adjacent normal tissue was determined by real-time PCR. The relationship between the expressions of LINC00261 and the clinic pathological characteristics including clinical stage, pathological type, histological grade and lymph node metastasis in LSCC was analysed according to the clinical data. Result:①The expression of LINC00261 was significantly decreased in the LSCC tissue compared with the normal laryngeal tissue(P<0.01).②In clinical stage grouping, there were no statistical differences of the quantity of LINC00261 expression among supraglottic, glottic and subglottic LSCC(P>0.05).In histological differentiation grouping, LINC00261 had no significant changes in poorly differentiated LSCC compared with the well and moderately differentiated LSCC(P>0.05). In histological grade grouping, the expression of LINC00261 in T1+T2 stages was significantly higher than T3+T4 stages(P<0.05). Moreover, the expression of LINC00261 in LSCC with lymph node metastasis was significantly lower than that without of lymph node metastasis(P<0.05). Conclusion:Down regulation of LINC00261 in laryngeal carcinoma may contribute to the carcinogenesis and development of laryngeal carcinoma. The decreased expression of LINC00261 maybe relative to T term degree and lymphamatic metastasis of laryngeal carcinoma.

Abstract
In 2008, American Academy of Otolaryngology-Head and Neck Surgery Foundation(AAO-HNSF)published the first clinical practice guideline for Benign Paroxysmal Positional Vertigo (BPPV) based on evidence-based methodology. The primary purposes of this guideline were to improve quality of care and outcomes for BPPV by enhancing the accuracy and efficacy of diagnosis of BPPV, reduce the inappropriate use of vestibular suppressant, and decrease the inappropriate use of ancillary examinations. The guideline was updated in 2017. This paper aimed at interpreting the updated guideline with a focus on diagnosis and ancillary tests section. Changes from the prior guideline include removal of the "no recommendation" for audiometric; expansion of the recommendations with respect to radiographic and vestibular testing, and broadening out the overall framework of differential diagnosis regarding BPPV.

Abstract
Sparganosis is a parasitic disease caused by plerocercoid larvae of the genus Spirometra. In China, the main source of sparganosis is from Guangdong, 16.1% of the country's human sparganosis cases occur in this province. Frequent international trade of amphibians and reptiles in Guangdong may introduce new species of Spirometra into the local market. In this study, a large-scale, high-intensity sampling survey was conducted to find out the causative species and epidemic situation of Sparganosis in Guangdong. The prevalence of sparganum infection in five species of frogs (Boulengerana guentheri, Fejervarya multistriata, Hoplobatrachus chinensis, Pelophylax nigromaculatus and Quasipaa spinosa) and nine species of snakes (Elaphe carinata, Lycodon rufozonatum, Hypsiscopus plumbea, Ptyas dhumnades, P. korros, P. mucosa, Naja atra, Sinonatrix annularis and Xenochrophis piscator) was investigated in Guangdong, Southern China from May 2014 to August 2015. The results showed that 9.8% (50/511) of the frogs and 40.8% (141/ 346) of snakes were found to be infected by plerocercoids (spargana). To identify the species of the collected spargana, a partial sequence of the mitochondrial cytochrome c oxidase subunit1 gene (cox1) was amplified and sequenced. Phylogenetic analysis identified all the spargana specimens as Spirometra erinaceieuropaei. Our study indicated that S. erinaceieuropaei, a highly pathogenic parasite, is the only causative agent of sparganosis in Guangdong, China. This study suggests that the large numbers of frogs and snakes in food markets in Guangdong may impact public health in China by transmitting S. erinaceieuropaei sparganum. Additional steps should be considered by the governments and public health agencies to prevent the risk of food-associated Spirometra infections in humans in China.

Abstract
Non-syndromic oral clefts (NSOC) are among the most common birth defects. The prevalence of NSOC is 1.13-1.30 per 1 000 live births in China, which is higher than those in other major ethnic groups. The etiology of NSOC is complex and heterogeneous, which involves both genetic and environmental risk factors. Although genome-wide association studies have identified a number of risk loci, these loci can only account for a small proportion of the heritability of NSOC. The next-generation sequencing research provides new ideas for further exploring the genetic risk factors of NSOC. This paper summaries the progress in the next-generation sequencing research of NSOC.

Abstract
Autoimmune hepatitis (AH) is usually manifested as chronic hepatitis in clinics; it may evolve to liver cirrhosis, hepatic failure, and even death if treatment is delayed. To investigate the clinical efficacy of glucocorticoids in combination with ursodesoxycholic acid in the treatment of glucocorticoids in combination with ursodesoxycholic acid, one hundred and twenty patients with AH who were admitted to the hospital from February 2014 and February 2016 were selected and randomly divided into an observation group and a control group using random number table. Patients in the control group were treated by glucocorticoids only, while patients in the observation group were treated by ursodesoxycholic acid and glucocorticoids. Patients in both groups were treated for six months. The clinical efficacy of the two groups was evaluated after treatment. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), direct bilirubin (DBIL) and total bilirubin (TBIL) of the two groups both decreased after treatment (P less than 0.05), the improvement of the level of liver function of the observation group was superior to that of the control group, and the difference was statistically significant (P less than 0.05); after treatment, the levels of serum immunoglobulin G (IgG) and immunoglobulin m (IgM) of both groups significantly reduced after treatment, and the difference within groups before and after treatment had no statistical significance (P less than 0.05). The reduction of the immunological indicators of the observation group was more remarkable after treatment, and the difference between the two groups had statistical significance (P>0.05). The complete remission rate of the observation group was significantly higher than that of the control group; the incidence of adverse reactions was lower than that of the control group, and the difference had statistical significance (P less than 0.05). Thus it can be concluded that glucocorticoids in combination with ursodesoxycholic acid has favorable efficacy in treating AH as it can promote the improvement of liver function and effectively reduce the dose of glucocorticoids and the incidence of adverse reactions. The therapy is of great clinical values.

Abstract
Magnetic reconnection is believed to be the main driver to transport solar wind into the Earth's magnetosphere when the magnetopause features a large magnetic shear. However, even when the magnetic shear is too small for spontaneous reconnection, the Kelvin-Helmholtz instability driven by a super-Alfvénic velocity shear is expected to facilitate the transport. Although previous kinetic simulations have demonstrated that the non-linear vortex flows from the Kelvin-Helmholtz instability gives rise to vortex-induced reconnection and resulting plasma transport, the system sizes of these simulations were too small to allow the reconnection to evolve much beyond the electron scale as recently observed by the Magnetospheric Multiscale (MMS) spacecraft. Here, based on a large-scale kinetic simulation and its comparison with MMS observations, we show for the first time that ion-scale jets from vortex-induced reconnection rapidly decay through self-generated turbulence, leading to a mass transfer rate nearly one order higher than previous expectations for the Kelvin-Helmholtz instability.

Abstract
OBJECTIVE To compare the difference between non-operative and operative treatment of humeral shaft fractures. METHODS From March 2005 to October 2012, 252 cases of humeral shaft fractures were treated and were adequately followed up. According to the treatment methods, the patients were divided into 2 groups: the non-operative group and the operative group. In the non-operative group, there were 76 cases treated with plaster/small splint fixation,meanwhile there were 176 cases treated with internal fixation either by plating or by nailing in the operative group. The follow-up parameters included: fracture healing rate, fracture union time, complications rate, Constant- Murley shoulder score and Mayo elbow score. RESULTS The mean follow-up period was (31.24±20.06) months (ranging 6 to 103 months). There were no statistical differences in age, open fracture number, fracture site and Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification between the non-operative group and the operative group. The fracture healing rate: the non-operative group: 96.1%(72/76), the operative group: 97.7%(172/176), P=0.46; the fracture union time: the non-operative group: (10.24±2.93) weeks, the operative group: (10.69±2.51) weeks, P=0.22; the complication rate: the non-operative group: 5.3%(4/76),the operative group: 15.3%(27/176), P=0.03. The complications included: nonunion: the non-operative group: 3.95%(3/76), the operative group: 2.3%(4/176), P=0.434; radial nerve palsies: the non-operative group: 0%(0/76), the operative group: 5.7%(10/176), P=0.035; bone split: the non-operative group: 0%(0/76), the operative group: 1.7%(3/176), P=0.556; elbow stiffness: the non-operative group:1.3%(1/76), the operative group: 0.6%(1/176), P=1.000; shoulder pain: the non-operative group:0%(0/76), the operative group: 5.1%(9/176), P=0.061. The Constant-Murley shoulder score: the non-operative group: 97.37±4.94, the operative group: 96.34±6.88, P=0.244. The Mayo elbow score: the non-operative group: 99.80±1.72, the operative group: 99.49±2.73,P=0.923. CONCLUSION The results of non-operative treatment of humeral shaft fractures appeared with excellent results with lower complications rate compared with that of the operative treatment.

Abstract
Objective: To explore the safety and validity of endoscopic cricopharyngeal myotomy in patients with cricopharyngeal achalasia. Methods: A total of 19 patients with cricopharyngeal achalasia suffered from sustained dysphagia were enrolled in this study. The patients were divided into transcervical cricopharyngeal myotomy(CPM) group and endoscopic CPM (ECPM) group. Swallowing function and complications were evaluated.SPSS7.0 software was used to analyze the data. Results: The swallowing function improved significantly in seven patients in ECPM group, and 9 patients improved in CPM group.The video fluoroscopic swallowing study(VFSS)-swallowing score, VFSS-aspiration score and drinking test score were (3.1±1.1), (3.4±0.8) and (2.0±0.6)in post-ECPM, (3.4±1.4), (3.0±0.9) and (2.2±0.6)in post-CPM. No statistical difference was found in validity between CPM group and ECPM group(t=-0.435, t=1.086, t=-0.607, P>0.05). No statistical difference was observed on the occurrence of complication between two groups. Only one patient had subcutaneous emphysema after operation in ECPM. Conclusions: New surgical instruments and endoscopic surgical technique were safe and effective for cricopharyngeal achalasia. Because these instruments are cheaper, laryngeal endoscopic cricopharyngeal myotomy is easier to be popularized more easily than microscopic laser assistted CPM.

Abstract
Objective:The aim of this study is to investigate the distribution of IL-10, CD14 and CD68 in the tumor microenvironment of LSCC with the clinicopathologic factors. Method:We detected the expressions of IL-10, CD14 and CD68 in 46 primary LSCC tumor tissues by immunohistochemistry staining and explore the relationship between them and clinicopathologic factors. Result:We found that the expressions of IL-10, CD14 and CD68 were significantly correlated with clinical stage and T stage (P<0.01). IL-10 and CD14 were correlated with lymph node metastasis (P<0.01), and CD68 was correlated with pathological differentiation (P<0.05). There is a positive correlation trend between the expression of IL-10 and CD14 (P<0.01). Conclusion:We confirm that the high level expressions of IL-10, monocytes and TAMs contribute to the tumor development of LSCC and there is a positive correlation between the expression of IL-10 and monocytes.

Abstract
Objective: To investigate the clinical and immunological laboratory features, mutations in SH2D1A gene and SAP protein expression in four children of two families with X-linked lymphoproliferative disease type 1(XLP-1). Method: Four patients (Family A including Patient 1 and Patient 2, Family B including Patient 3 and Patient 4) and their maternal relatives were enrolled in this study. The clinical manifestation, EBV infection status and chest CT scan were analyzed. The absolute and relative numbers of lymphocyte subsets, T lymphocyte proliferative response, SAP protein expression were assessed by flow cytometry. Quantification of signal joint TCR rearrangementexcision circle (sjTRECs), CDR3 spectratyping of TCRvβ and gene mutation of SH2D1A were detected by PCR based on genomic DNA or cDNA. Result: Four male patients from two families were diagnosed with XLP-1. The ages of disease onset were more than 1 year, more than 1 year, more than 1 month and 6 months. The ages at diagnosis were nine years and ten months, sixteen years and eight months, fourteen years and ten months, four years and nine months. All patients had recurrent infections and EBV infection. Patients 1, 2, and 3 had agammaglobulinemia and Patient 4 had hypogammaglobulinemia. Chest CT scan showed all patients had atelectasis and pneumonia, and Patient 3 had bronchiectasis. Patient 3 was diagnosised as Burkitt lymphoma. For immunological function, all patients exhibited reduced CD4/CD8 ratios, increased numbers of exhausted T lymphocyte, decreased number of NK cell. The numbers of total B lymphocyte and naïve B lymphocyte were normal, but the number of memory B lymphocyte declined in all cases. Four patients' copy numbers of sjTRECs were low and CDR3 spectratypings of TCRvβ showed mildly skewed. But their T lymphocyte proliferative response was normal. SAP protein expression in four cases were measured by flow cytometry. Two patients from Family A were absent and two patients from Family B showed decreased values. SH2D1A gene sequence analysis showed that the patients of Family A harbored a nonsense mutation (c.163 C>T; p.R55X) in exon 2. Their mother and two sisters were carriers. A missense mutation of SH2D1A gene (c.278 G>A; p.G93D) in exon 3 was found in the patients of Family B. The mother was carrier. Four patients remain survived, Patient 3 gave up treatment, other three patients received IVIG therapy. Conclusion: Four patients with XLP-1 from two families characterized by agammaglobulinemia have an extreme vulnerability to Epstein-Barr virus (EBV) infection. The functions of T cell, B cell and NK cell are impaired at different stages. The detection of SAP protein and SH2D1A gene are the key methods for diagnosis of XLP-1.

Abstract
Many cases of liver carcinoma miss the opportunity of surgical treatment because of hidden onset and delayed diagnosis. In recent years, interventional treatment has gradually become a non-surgical method for treating liver carcinoma. To discuss the effects of oxaliplatin in combination with epirubicin in the treatment and its influence on prognosis, this study randomly selected 218 advanced primary liver carcinoma patients from Binzhou Peoples Hospital, Binzhou, China and divided them into a control group (n=109) and an observation group (n=109). Patients in both groups were given interventional treatment. Patients in the control group were perfused with oxaliplatin, while patients in the observation group were perfused with oxaliplatin and epirubicin. The effectsat 6-month and 12-month survival rates were compared between the two groups. The results demonstrated that the overall effective rate and clinical benefit rate of the observation group were much higher than those of the control group (30.3% vs 11.9%; 79.8%; vs 44.3%) (P less than 0.05). The serum Alpha Fetal Protein (AFP) and Carcino Embryonie Antigen (CEA) levels of the observation group were much lower than those of the control group; the Karnofsky performance score of the observation group was much lower than that of the control group; the two differences had statistical significance (P less than 0.05). The 6-month survival rate of the observation group was 91.67%, higher than that of the control group (86.11%) (P>0.05). The 12-month survival rate of the observation group was 83.33%, much higher than that of the control group (61.11%) (P less than 0.05). The difference of the incidence of adverse reactions between the two groups had no statistical significance (P>0.05). Thus, it can be concluded that oxaliplatin in combination with epirubicin can improve survival quality, extend survival time, and decrease the serum AFP and CEA levels in the treatment of primary liver carcinoma, with definite effects but without aggravating toxic and side effects. Therefore, the therapy has important clinical value.

Abstract
T-cell proliferation is regulated by ubiquitination but the underlying molecular mechanism remains obscure. Here we report that Lys-48-linked ubiquitination of the transcription factor KLF4 mediated by the E3 ligase Mule promotes T-cell entry into S phase. Mule is elevated in T cells upon TCR engagement, and Mule deficiency in T cells blocks proliferation because KLF4 accumulates and drives upregulation of its transcriptional targets E2F2 and the cyclin-dependent kinase inhibitors p21 and p27. T-cell-specific Mule knockout (TMKO) mice develop exacerbated experimental autoimmune encephalomyelitis (EAE), show impaired generation of antigen-specific CD8+ T cells with reduced cytokine production, and fail to clear LCMV infections. Thus, Mule-mediated ubiquitination of the novel substrate KLF4 regulates T-cell proliferation, autoimmunity and antiviral immune responses in vivo. The E3 ligase Mule has been previously reported to be essential for B cell development and function by modulating p53 ubiquitination and degradation. Here Hao et al. identify KLF4 as a novel ubiquitination target of Mule and show it controls T cell proliferation and autoimmunity.

Abstract
Objective:To describe the therapeutic effect of transoral endoscopic minimally invasive surgery for hypopharyngeal postcricoidarea and upper esophageal lesions. Method:Transoral endoscopic minimally invastive surgery was carried out in fifteen patients.There were 7 patients with primary tumors on the postcricoid area, including three squamous cell carcinoma(2 cases T2N0M0,1 case T2N2cM0),two cavernous hemangioma, one giant fibrovascular polyp and one recurrent lipofibroma. The transoral endoscopic tumors resection en bloc was performed in all of them. Adjuvant postoperative radiation therapy was applied in cases of cancer, and bilateral neck dissections was performed in the T2N2cM0 case; There were other eight patients with upper esophageal lesions , seven cases dysphagia was caused by stroke and one case was Zenker diverticulum, treated by endoscopic cricopharyngeal myotomy ordiverticulotomy. Result:The en bloc resection endoscopically was achieved in all of patients with tumors on the postcricoid area. All surgical resection margins were negative.The two cases of postcricoid cancer and four benign tumor were followed up 16-30 months and 2-12 months respectively, and all of the cases were not local recurrence. A recent patient with postcricoid cancer had not finished postoperative adjuvant radiation therapy. The endoscopic cricopharyngeal myotomy was effective in 4 out of 7 patients,nasogastric feeding was no longer required.Significant improvement occurred in Zenker diverticulotomy patient, due to the return of physiological deglutition, and Barium swallow study showing disappearance of the diverticulum after one month.The effects of minimally invasive threatment were satisfactory,such as not need tracheotomy and early oral feeding, shorter hospital stay and less postoperative complications. Conclusion:Transoral endoscopic surgery is minimally invastive, safe and effective treatment alternative for some hypopharyngeal postcricoid area and upper esophageal lesions.

Abstract
Mutations in the isocitrate dehydrogenase-1 gene (IDH1) are common drivers of acute myeloid leukemia (AML) but their mechanism is not fully understood. It is thought that IDH1 mutants act by inhibiting TET2 to alter DNA methylation, but there are significant unexplained clinical differences between IDH1- and TET2-mutant diseases. We have discovered that mice expressing endogenous mutant IDH1 have reduced numbers of hematopoietic stem cells (HSCs), in contrast to Tet2 knockout (TET2-KO) mice. Mutant IDH1 downregulates the DNA damage (DD) sensor ATM by altering histone methylation, leading to impaired DNA repair, increased sensitivity to DD, and reduced HSC self-renewal, independent of TET2. ATM expression is also decreased in human IDH1-mutated AML. These findings may have implications for treatment of IDH-mutant leukemia.
