Evading host immunity killing is a critical step for virus survival. Inhibiting viral immune escape is crucial for the treatment of viral diseases. Serine/threonine kinase 39 (STK39) was reported to play an essential role in ion homeostasis. However, its potential role and mechanism in viral infection remain unknown. In this study, we found that viral infection promoted STK39 expression. Consequently, overexpressed STK39 inhibited the phosphorylation of interferon regulatory factor 3 (IRF3) and the production of type I interferon, which led to viral replication and immune escape. Genetic ablation or pharmacological inhibition of STK39 significantly protected mice from viral infection. Mechanistically, mass spectrometry and immunoprecipitation assays identified that STK39 interacted with PPP2R1A (a scaffold subunit of protein phosphatase 2A (PP2A)) in a kinase activity-dependent manner. This interaction inhibited DDB1 and CUL4 associated factor 1 (DCAF1)-mediated PPP2R1A degradation, maintained the stabilization and phosphatase activity of PP2A, which, in turn, suppressed the phosphorylation of IRF3, decreased the production of type I interferon, and then strengthened viral replication. Thus, our study provides a novel theoretical basis for viral immune escape, and STK39 may be a potential therapeutic target for viral infectious diseases.

Congenital orofacial cleft, the most common birth defect in the maxillofacial region, exhibits a wide range of prognosis depending on the severity of deformity and underlying etiology. Non-syndromic congenital orofacial clefts typically present with milder deformities and more favorable treatment outcomes, whereas syndromic congenital orofacial clefts often manifest with concomitant organ abnormalities, which pose greater challenges for treatment and result in poorer prognosis. This consensus provides an elaborate classification system for varying degrees of orofacial clefts along with corresponding diagnostic and therapeutic guidelines. Results serve as a crucial resource for families to navigate prenatal screening results or make informed decisions regarding treatment options while also contributing significantly to preventing serious birth defects within the development of population.

OBJECTIVE To preliminarily assess the horizontal sound localization and its influencing factors in patients with unilateral sudden sensorineural hearing loss during the acute phase.METHODS The azimuth discrimination test and azimuth identification test were completed,with the speech sound(65 dB SPL)as the stimulus.The minimum audible angle(MAA)and root-mean-square error(RMSE)were obtained,and the RMSE of the affected side and the healthy side were calculated respectively.According to the WHO(2021)hearing loss classification criteria,the data were analyzed based on the pure-tone average(PTA)of the affected ear.And the best resident hearing at each frequency of the affected ear was recorded.RESULTS The performance of the unilateral sudden sensorineural hearing loss patients in the sound localization varied greatly.Some performed close to the normal level,while others completely lost the ability to localize sound.The RMSE of the moderate hearing loss group(≥35 dB HL)was significantly higher than that of the normal hearing group(P<0.01),the MAA of the moderate to severe hearing loss group(≥50 dB HL)showed statistically significant differencescompared with normal hearing group(P<0.001).The RMSE of the affected side of patients in the severe and above hearing loss group was significantly larger than that of the healthy side.Regression analysis showed that the best resident hearing at each frequency of the affected ear was the most significant factor affecting MAA(R2=0.572,P<0.001)and RMSE(R2=0.768,P<0.001).CONCLUSION The horizontal sound localization of unilateral sudden sensorineural hearing loss patients in the acute phase varies greatly.When the PTA of the affected side reaches moderate hearing loss,the localization ability is significantly lower than that of normal-hearing individuals.The best resident hearing at each frequency of the affected ear is the key factor affecting the localization ability.

Objective:To evaluate the clinical effect of modified posterior pharyngeal flap surgery in the treatment of velopharyngeal insufficiency.Methods:Clinical data of patients with cleft lip and palate diagnosed with velopharyngeal insufficiency and undergoing modified posterior pharyngeal flap surgery in Peking University School and Hospital of Stomatology from January 2018 to May 2022 were retrospectively analyzed. The traditional posterior pharyngeal flap surgery was improved by combining the modern concept and method of soft palate muscle reconstruction, and performed modified posterior pharyngeal flap surgery to correct velopharyngeal insufficiency. Preoperative and postoperative follow-up were performed including speech evaluation (classifying as none, mild, moderate, moderate to severe hypernasality and nasal emission), nasopharyngeal fiberscope (classifying velopharyngeal insufficiency as mild, moderate, or severe), lateral cephalometric radiographs (resting position and /i/ position), and the Nasal Obstruction Symptom Evaluation (NOSE) scale. The recovery of velopharyngeal function and nasal ventilation after the operation were statistically analyzed. The difference of resting velar length (RVL), effective working length (EWL) and angel of velar lifting (AVL) before and after the operation was compared by paired t-test to evaluate the clinical effect of surgery. P<0.05 indicates a statistically significant difference. Results:A total of 83 patients with velopharyngeal insufficiency were enrolled, including 44 males and 39 females, aged (13.04±11.31) years (4-53 years). 83 patients were followed up for 6-18 months after surgery, and all patients had primary wound healing without postoperative bleeding, perforation, or posterior pharyngeal flap detachment; 78 cases achieved complete velopharyngeal closure, the surgical success rate was 94%, three patients still had mild hypernasality and nasal emission after surgery, one patient still had moderate hypernasality and nasal emission after surgery, and one patient had severe hypernasality after surgery. The RVL was (29.27±6.01) mm before the operation and (36.88±6.51) mm after the operation.The EWL of the soft palate was (18.53±5.04) mm before the operation and (25.76±5.17) mm after the operation.The angel of velar lifting was 11.42°±11.65° before the operation and 15.91°±8.54° after operation. The differences were statistically significant ( P<0.01). 98%(81/83) patients had subjective nasal obstruction symptom in the short period after surgery (within one month), the nasal obstruction symptom evaluation (NOSE) score was 8.61±3.64. The long-term postoperative follow-up showed that the NOSE score was 3.06±2.92, and the difference was statistically significant ( P<0.01). Conclusion:Modified posterior pharyngeal flap surgery can significantly increase the resting velar length and effective working length, improve the movement ability of the soft palate, acquire functional reconstruction of velopharyngeal closure, improve speech function and achieve effectively surgical results.

Objective:To explore the association between polymorphisms of transforming growth factor-β(TGF-β)signaling pathway and non-syndromic cleft lip with or without cleft palate(NSCL/P)among Asian populations,while considering gene-gene interaction and gene-environment interaction.Methods:A total of 1 038 Asian NSCL/P case-parent trios were ascertained from an international consortium,which conducted a genome-wide association study using a case-parent trio design to investigate the genes affec-ting risk to NSCL/P.After stringent quality control measures,343 single nucleotide polymorphism(SNP)spanning across 10 pivotal genes in the TGF-β signaling pathway were selected from the original genome-wide association study(GWAS)dataset for further analysis.The transmission disequilibrium test(TDT)was used to test for SNP effects.The conditional Logistic regression models were used to test for gene-gene interaction and gene-environment interaction.Environmental factors collected for the study in-cluded smoking during pregnancy,passive smoking during pregnancy,alcohol intake during pregnancy,and vitamin use during pregnancy.Due to the low rates of exposure to smoking during pregnancy and al-cohol consumption during pregnancy(＜3％),only the interaction between maternal smoking during pregnancy and multivitamin supplementation during pregnancy was analyzed.The threshold for statistical significance was rigorously set at P=1.46 × 10-4,applying Bonferroni correction to account for multiple testing.Results:A total of 23 SNPs in 4 genes yielded nominal association with NSCL/P(P＜0.05),but none of these associations was statistically significant after Bonferroni's multiple test correction.How-ever,there were 6 pairs of SNPs rs4939874(SMAD2)and rs1864615(TGFBR2),rs2796813(TGFB2)and rs2132298(TGFBR2),rs4147358(SMAD3)and rs1346907(TGFBR2),rs4939874(SMAD2)and rs1019855(TGFBR2),rs4939874(SMAD2)and rs12490466(TGFBR2),rs2009112(TGFB2)and rs4075748(TGFBR2)showed statistically significant SNP-SNP interaction(P＜1.46 × 10-4).In contrast,the analysis of gene-environment interactions did not yield any significant results after being cor-rected by multiple testing.Conclusion:The comprehensive evaluation of SNP associations and interac-tions within the TGF-β signaling pathway did not yield any direct associations with NSCL/P risk in Asian populations.However,the significant gene-gene interactions identified suggest that the genetic architec-ture influencing NSCL/P risk may involve interactions between genes within the TGF-β signaling path-way.These findings underscore the necessity for further investigations to unravel these results and further explore the underlying biological mechanisms.
