Objective To examine the precise function of influenza A virus target genes(IATGs)in malignancy. Methods Using multi-omics data from the TCGA and TCPA datasets,33 tumor types were evaluated for IATGs.IATG expression in cancer cells was analyzed using transcriptome analysis.Copy number variation(CNV)was assessed using GISTICS 2.0.Spearman's analysis was used to correlate mRNA expression with methylation levels.GSEA was used for the enrichment analysis.Pearson's correlation analysis was used to examine the association between IATG mRNA expression and IC50.The ImmuCellAI algorithm was used to calculate the infiltration scores of 24 immune cell types. Results In 13 solid tumors,IATG mRNA levels were atypically expressed.Except for UCS,UVM,KICH,PCPG,THCA,CHOL,LAMI,and MESO,most cancers contained somatic IATG mutations.The main types of CNVs in IATGs are heterozygous amplifications and deletions.In most tumors,IATG mRNA expression is adversely associated with methylation.RT-PCR demonstrated that EGFR,ANXA5,CACNA1C,CD209,UVRAG were upregulated and CLEC4M was downregulated in KIRC cell lines,consistent with the TCGA and GTEx data. Conclusion Genomic changes and clinical characteristics of IATGs were identified,which may offer fresh perspectives linking the influenza A virus to cancer.

Objective To explore the clinical efficacy of video-assisted thoracoscopic intrathoracic fixation in the treatment of multiple rib fractures.Methods Clinical data of 93 cases of multiple rib fractures in our department from August 2019 to April 2022 were retrospectively compared.They were divided into thoracoscopic group(n=50)and traditional group(n=43)according to surgical methods.In the thoracoscopic group,the memory alloy rib plate was used for thoracoscopic intrathoracic fixation,and in the traditional group,the memory alloy rib plate was used for traditional thoracotomy to treat multiple rib fractures.The operation time,intraoperative blood loss,postoperative hospital stay,postoperative catheter duration,postoperative pain time,postoperative drainage volume,and postoperative complications were compared between the two groups.Results As compared with the traditional group,the thoracoscopic group had significantly shorter operation time[(96.1±24.7)min vs.(110.2±29.1)min,t=-2.526,P=0.013],less intraoperative blood loss[(76.0±38.4)ml vs.(140.2±80.8)ml,t=-4.767,P=0.000],shorter postoperative catheter duration[(3.9±1.6)d vs.(6.2±1.8)d,t=-2.739,P=0.008],less postoperative drainage volume[(132.4±53.9)ml vs.(157.9±50.5)ml,t=-2.345,P=0.021],shorter postoperative hospital stay[(5.8±2.5)d vs.(9.7±2.5)d,t=-4.397,P=0.000],and shorter pain time[(4.9±1.2)d vs.(5.8±1.4)d,t=-2.199,P=0.030].The incidence of postoperative pneumonia,atelectasis,and pleural effusion in the thoracoscopic group was significantly lower than that in the traditional group(P<0.05).Follow-ups at 1,3,and 12 months after surgery showed that the rib plate was firmly fixed without any displacement,deformation,or detachment.Conclusion Video-assisted thoracoscopic intrathoracic fixation in the treatment of multiple rib fractures has advantages of less trauma,less pain,faster recovery,and definite clinical results,which is worthy of clinical application and promotion.

This article aimed to explore the theoretical connotation and mechanism of clearing damp-heat method in the treatment of chronic kidney disease (CKD), provide theoretical support for clearing damp-heat method in the treatment of chronic kidney disease, and further explain the modern scientific connotation of "damp-heat impairing kidney". Modern Traditional Chinese Medicine (TCM) believes that damp-heat is an important pathogenesis of kidney damage. Clearing damp-heat method plays a key role in inhibiting CKD immune inflammatory response, improving oxidative stress and antagonizing renal fibrosis. The mechanism is mainly related to the regulation of TNF-α level, blocking NF-κB signaling pathway, inhibiting inflammatory cytokines, antagonizing TGF-β1 secretion and other pathways.

Cutaneous T-cell lymphomas are a relatively rare group of mature T-cell lymphomas mainly manifesting in the skin, and its common subtype is mycosis fungoides. Total skin electron irradiation is one of the important conventional treatment methods, but there are many disadvantages, such as uneven dose distribution, poor position repetition, and long treatment time, which affect the clinical efficacy and patient prognosis. With the emergence and gradual popularization of helical tomotherapy in recent years, more and more medical institutions are gradually expanding their applications in total skin irradiation due to their ability to treat ultra-long targets and achieve dose-sculpted distribution, aiming to further explore its good or bad, and confirm whether it can replace the traditional total skin electron irradiation. In this article, research progress on total skin irradiation using helical tomotherapy was reviewed, the development of treatment technology, clinical efficacy and current concerns and controversies were illustrated.

Objective:To explore the changing characteristics of self-efficacy, social support, psychological stress in patients with osteoporotic vertebral compression fractures (OVCFs) receiving conservative treatment at different treatment stages and their correlations with the recovery of lower back function.Methods:A total of 116 patients with acute OVCFs who were admitted to the Affiliated Hospital of Medical School, Ningbo University were selected from January 2017 to May 2019. Oswestry Disability Index (ODI) Questionnaire, General Self Efficacy Scale (GSES) , Perceived Social Support Scale (PSSS) and Perceived Stress Scale (PSS) were used to assess the lower back function, self-efficacy, social support and psychological stress of OVCFs patients. Questionnaires were filled out during outpatient reexamination or in-home follow-up, and the evaluation time was at the time of treatment and 1, 3, 6, and 12 months after conservative treatment. Analysis of variance and SNK- q test were used to explore the characteristics of each score over time, and linear regression analysis was used to explore the effects of GSES, PSSS, and PSS on ODI. Results:With the prolongation of treatment time, ODI, GSES, PSSS and PSS scores of OVCFS patients under conservative treatment showed a downward trend, and the scores at 3, 6 and 12 months after treatment were lower than those at 1 month after conservative treatment ( P<0.05) . The scores at 6 and 12 months after conservative treatment were lower than those at 3 months after conservative treatment ( P<0.05) . The scores at 12 months after conservative treatment were lower than that those at 6 months after conservative treatment ( P<0.05) . GSES, PSSS (total score, in-family support, out-of-family support) and PSS were independent influencing factors of ODI at one month after treatment ( P<0.05) . GSES, PSSS (total score, in-family support) and PSS were the influencing factors of ODI at 3 months after treatment ( P<0.05) . Conclusions:The self-efficacy and social support of conservatively treated patients with OVCFs are positively correlated with their lower back function, while psychological stress will reduce lower back function of such patients. It is suggested to add these non-physical factors to the rehabilitation nursing model and take appropriate intervention measures.
