Cylindromatosis gene is a kind of tumor suppressor genes, whose mutation or deletion will lead to the development of a cylindrical tumor. The deubiquitinating enzyme CYLD protein encoded by it is a member of the deubiquitinating enzyme family. CYLD alters the function of the target molecules by removing the ubiquitin chain linked to the substrate protein K63, and participates in the regulation of signaling pathways, such as NF-κB, JNK and Wnt. This article reviews the recent year’s research progress of CYLD, especially its negative regulatory role in the progression of liver-related diseases.

Objective:To investigate the effect of posterior nasal neurectomy(PNN) with pharyngeal neurectomy (PN) on chronic sinusitis with nasal polyps (CRSwNP)complicated with perennial allergic rhinitis (PAR). Methods:83 patients with perennial allergic rhinitis combined with chronic group-wide sinusitis with nasal polyps who attended our hospital from July 2020 to July 2021 were selected. All patients underwent conventional functional endoscopic sinusitis surgery(FESS)+ nasal polypectomy. Patients were divided according to whether they underwent PNN+PN. 38 cases in the experimental group underwent FESS combined with PNN+PN; 44 cases in the control group underwent conventional FESS alone. All patients underwent the VAS, RQLQ, and MLK before treatment, and at 6 months and 1 year after surgery. Meanwhile, other relevant data were collected and the preoperative and postoperative follow-up data were collected and analyzed to assess the differences between the two groups. Results:The total postoperative follow-up period was 1 year. The recurrence rate of nasal polyps at 1 year postoperatively and the nasal congestion VAS score at 6 months postoperatively were not statistically significant in the two groups(P>0.05). However, the patients in the experimental group had statistically significantly lower effusion and sneezing VAS scores, MLK endoscopy scores and RQLQ scores at 6 months and 1 year postoperatively, and nasal congestion VAS scores at 1 year postoperatively compared to the control group(P<0.05). Conclusion:For patients with perennial AR complicated with CRSwNP, the combination of the PNN+PN in FESS can significantly improve the short-term curative effect, and PNN+PN is a safe and effective surgical treatment.

Objective:
The aim of this study is to evaluate the efficacy of endoscopic surgery and conventional surgery combined with radiotherapy in the treatment of Neuroblastoma.
Method:
Forty-three patients with olfactory neuroblastoma undergoing surgery combined with radiotherapy were retrospectively analyzed. The patients were divided into endoscopic surgery and conventional surgery. All patients received postoperative radiotherapy at a dose of 60-70 Gy, the 5-year survival rate and local recurrence time of the two groups were compared, and the therapeutic effects of endoscopic surgery and traditional surgery were compared.
Result:
Through survival analysis, the 5-year overall survival rates of the traditional surgery group and the endoscopic surgery group were 50% and 58% (P=0.560), the local recurrence rates were 44% and 48% (P=0.288), and the mean recurrence time was 5.6 months and 12.5 months (P=0.032).
Conclusion
There was no difference between endoscopic surgery and conventional surgery combined with radiotherapy in the treatment of Neuroblastoma, and the time of local recurrence was significantly prolonged. In early Neuroblastoma, endoscopic sinus surgery may be superior to open surgery in terms of efficacy and patient survival.

The secondary structures of hepatitis C virus (HCV) RNA and the cellular proteins that bind to them are important for modulating both translation and RNA replication. However, the sets of RNA-binding proteins involved in the regulation of HCV translation, replication and encapsidation remain unknown. Here, we identified RNA binding motif protein 24 (RBM24) as a host factor participated in HCV translation and replication. Knockdown of RBM24 reduced HCV propagation in Huh7.5.1 cells. An enhanced translation and delayed RNA synthesis during the early phase of infection was observed in RBM24 silencing cells. However, both overexpression of RBM24 and recombinant human RBM24 protein suppressed HCV IRES-mediated translation. Further analysis revealed that the assembly of the 80S ribosome on the HCV IRES was interrupted by RBM24 protein through binding to the 5'-UTR. RBM24 could also interact with HCV Core and enhance the interaction of Core and 5'-UTR, which suppresses the expression of HCV. Moreover, RBM24 enhanced the interaction between the 5'- and 3'-UTRs in the HCV genome, which probably explained its requirement in HCV genome replication. Therefore, RBM24 is a novel host factor involved in HCV replication and may function at the switch from translation to replication.
