Colorectal cancer (CRC) poses a severe global health challenge with high incidence and mortality rates. USP37 has been identified as the bona fide deubiquitinase of SND1, playing a critical role in stabilizing SND1, thereby augmenting its oncogenic potential. The interaction between USP37 and SND1 was confirmed through extensive proteomics, ubiquitinomics, and interactomics, underscoring their synergistic effects on CRC proliferation and metastasis. Additionally, CDK1 has emerged as a pivotal regulator of USP37, phosphorylating it at threonine 631 rather than serine 628, enhancing its deubiquitinase activity, and consequently stabilizing SND1 to drive CRC malignancy further. Histological analyses of human CRC samples linked the upregulation of CDK1 and USP37 with increased SND1 levels and poor patient prognosis. High-throughput virtual screening and subsequent experimental validation identified Dacarbazine as a pharmacological inhibitor of USP37, and its inhibition disrupted SND1 stability, hindering CRC cell proliferation and metastasis. This study reveals a novel and promising molecular mechanism driving CRC progression through the CDK1-USP37-SND1 axis, highlighting the clinical importance of targeting this pathway to improve patient outcomes.

Objective To analyze the clinical value of temperature-controlled ablation radio-frequency(TCAR)as a surgical option for the treatment of pediatric snoring.Method This study selected 120 children with snoring from January 2021 to December 2022 for observation.They were divided into the control group(n=60,receiving tonsil removal+nasal underopia gland scraping therapy)and the observation group(n=60,using TCAR to remove patients with gland samples and tonsils)using a random number table method.The clinical efficacy,surgery-related situation and sleep quality were compared.Results The effective rate of observation group was 93.33%,which was significantly higher than 76.67%of the control group.The intraoperative blood loss in the observation group was less than that in the control group,the operation time,symptom remission time and hospital stay were shorter,and the VAS was lower than those in the control group,with statistical significance(P<0.05).There was no statistically significant difference in the comparison of Quebec sleep questionnaire(QSQ)score,Epworth sleepiness scale(ESS),and disease specific quality of life for children with obstructive sleep apnea 18 items survey(OSA-18)between the two groups of patients before surgery(P>0.05);The postoperative ESS and OSA-18 of the observation group were lower than those of the control group,while the QSQ score was higher than that of the control group,with statistical significance(P<0.05).After surgery,the QSQ scores of the two groups were higher than before surgery,while the ESS and OSA-18 of the two groups were lower than before surgery,with statistical significance(P<0.05).The postoperative complications in the observation group(1.67%)was lower than that of the control group(11.67%),with statistical significance(P<0.05).Conclusion Compared with traditional surgery,TCAR for tonsillectomy and adenoidectomy in children with snoring can improve clinical efficacy,further improve ventilation capacity,reduce patient pain,shorten symptom relief time,improve sleep quality and living standards,and reduce the risk of postoperative complications.

OBJECTIVE:To establish an HPLC method for determining the contents of Quercetin and Isorhamnetin in Bupleurum.smithii var.parvifolium Shan et Y.Li.METHODS:The HPLC was performed on Kromasil column C18(250mm? 4.6mm,5? m),using methanol-0.4% phosphoric acid(55∶ 45)as mobile phase,with flow rate at 1.0mL? min-1 and detection wavelength at 256nm.RESULTS:The linear range of Quercetin was 0.08~ 0.40? g(r=0.999 6),with an average recovery rate of 101.02%(RSD=1.53%);that of Isorhamnetin was 0.06~ 0.30? g(r=0.999 2),with an average recovery rate of 101.26%(RSD=2.95%).CONCLUSION:This method is simple and accurate with good reproducibility.It is suitable for the quality control of Bupleurum.smithii var.parvifolium Shan et Y.Li.
