Human papilloma virus (HPV), a cancer-causing DNA virus, is a most common sexually transmitted virus and one of the major public health problems worldwide currently. Although HPV infection is relatively common in men, routine HPV detection is still difficult to be applied in clinical practice due to the lack of standard HPV detection methods and the complexity of its detection. Recent studies have explored the relationship between HPV and genitourinary tumors, revealed different results because of geographic differences, histological subtypes and detection methods, and stressed the importance of clarifying the role of HPV in the development and progression of genitourinary tumors. This review focuses on the complicated relationship of HPV with male genitourinary tumors, reveals its main carcinogenic mechanisms, and presents a new insight into the impact of HPV on the genitourinary system.

BACKGROUND:The use of vancomycin in total knee arthroplasty is a controversial strategy for the prevention of incisional infection.At present,there is little evidence to evaluate the efficacy of this preventive measure in China. OBJECTIVE:To evaluate the efficacy of local vancomycin in the prevention of early postoperative incision infection during total knee arthroplasty. METHODS:120 patients with osteoarthritis of the knee who received unilateral total knee arthroplasty for the first time at Department of Joint Surgery of First Affiliated Hospital of Anhui Medical University from March to June 2022 were included in this study.They were randomly divided into the observation group and the control group,with 60 cases in each group.All patients gave informed consent to the treatment plan.In the observation group,1 g of vancomycin was applied intraoperatively;in the control group,no vancomycin was applied intraoperatively.Erythrocyte sedimentation rate,C-reactive protein,fever rate on seven consecutive days after surgery,degree of knee joint swelling,cumulative drainage volume,and incidence of periprosthetic joint infection were recorded in two groups of patients on days 1,3,and 5 after surgery so as to evaluate the efficacy of topical vancomycin in total knee arthroplasty for the prevention of incision infection in the early postoperative period. RESULTS AND CONCLUSION:(1)The differences in erythrocyte sedimentation rate and C-reactive protein between the two groups on days 1,3,and 5 after surgery were not significant(P>0.05).(2)The difference in fever rate between the two groups for 7 consecutive days after surgery was not significant(P>0.05).(3)There was no significant difference in the degree of postoperative knee swelling and cumulative drainage flow between the two groups(P>0.05).(4)The difference in the incidence of periprosthetic joint infection one year after surgery was not significant between the two groups(P>0.05).(5)The results suggest that the local use of vancomycin in total knee arthroplasty has not shown significant efficacy in preventing incision infection in the early postoperative period.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective:To investigate the effect of anthoxanthin on the proliferation and apopto-sis of human gastric cancer cell line SGC7901 and its possible mechanism.Methods:SGC7901 was cultured in the medium containing different concentrations(0,20,40,80 μ mol/L)of antho-cyanin.Hoechst staining,MTT colorimetry and flow cytometry were used to verify the effect of Form on the inhibition rate,cell cycle,nuclear morphology and apoptosis.Western Blotting was used to test the level of β-Catenin、p-β-Catenin,CyclinD1,CDK4,p-AKT,AKT,BCL-2,BAX,caspase3 and other proteins.The mRNA expression of BCL-2,CDK4,CDK6,AKT,CyclinD1,BAX,Caspase3 was detected by RT-PCR.Results:MTT results showed that the inhibitory effect of Form on SGC7901 was concentration dependent and time dependent.Hoechst staining showed that the cells in the experimental group(20,40,80 μ mol/L),the phenomenon of pyknosis and dissolution of the nucleus,even granular aggregation after rupture.Flow cytometry showed that the apoptosis rate of the experimental group(20 μ mol/L,40 μ mol/L,80 μ mol/L)was 17.0％,21.5％,32.5％respectively after treated with different concentrations of Form for 48 hours,which was positively correlated with the drug concentration.RT-PCR showed that caspase3 and BAX mRNA expression increased with the increase of Form intervention concentration(P＜0.01);the mRNA expression of BCL-2,CDK4,CDK6,AKT,CyclinD1 decreased(P＜0.01).WB results showed that β-Catenin、p-β-Catenin,Cy-clinD1,CDK4 and p-AKT,AKT,BCL-2 decreased with the increase of Form intervention concentra-tion(P＜0.01);The relative expression of caspase3,BAX and other proteins increased(P＜0.01).Con-clusion:Form can promote apoptosis of SGC7901,and the possible mechanism is to inhibit Wnt/β-Catenin signal;it also mediates the activation of Caspase family.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the molecular mechanism of verbascoside against acute lung injury(ALI)by network pharmacology and molecular docking methods,and to validate the findings experimentally.Methods The 2D structure of verbascoside was obtained from the Pubchem database.Active ingredient targets of verbascoside were acquired from Pharmmapper database and Swiss Target Prediction database.Active component targets of ALI were acquired from datebase such as Gene Cards,OMIM,and DisGeNET.Common targets between verbascoside and ALI were determined by overlapping these sets.PPI network for potential targets was constructed using String database and Cytoscape software.The intersection targets were imported into the DAVID database for enrichment analysis of GO biological processes,KEGG signaling pathway and the pathway target genes.Molecular docking between verbascoside and core targets was performed using Autodock vina software.The mRNA expression level of core genes was validated using real-time quantitative PCR(RT-qPCR),and the expression of related proteins was detected using Western blotting.Results A total of 150 target genes of verbascoside against ALI were screened,and the key targets of verbascoside against ALI mainly involve pathways such as Rap1 signaling pathway,PI3K-Akt signaling pathway and MAPK signaling pathway.Verbascoside docked well with the core target molecules.RT-qPCR results showed that,compared with the control group,the mRNA expression levels of HSP90AA1,ALB,TP53,TNF,INS,and HRAS were significantly decreased in cells after the effect of verbascoside(P<0.05);Western blotting indicated that,compared with the model group,verbascoside treatment significantly reduced the expression of p-Akt,p-p38,and p-ERK proteins(P<0.05).Conclusion Verbascoside could inhibit MAPK,Rap1 and PI3K/Akt signaling pathways to exert its anti-ALI effects.

Management and treatment of terminal metastatic castration-resistant prostate cancer (mCRPC) remains heavily debated. We sought to investigate the efficacy of programmed cell death 1 (PD-1) inhibitor plus anlotinib as a potential solution for terminal mCRPC and further evaluate the association of genomic characteristics with efficacy outcomes. We conducted a retrospective real-world study of 25 mCRPC patients who received PD-1 inhibitor plus anlotinib after the progression to standard treatments. The clinical information was extracted from the electronic medical records and 22 patients had targeted circulating tumor DNA (ctDNA) next-generation sequencing. Statistical analysis showed that 6 (24.0%) patients experienced prostate-specific antigen (PSA) response and 11 (44.0%) patients experienced PSA reduction. The relationship between ctDNA findings and outcomes was also analyzed. DNA-damage repair (DDR) pathways and homologous recombination repair (HRR) pathway defects indicated a comparatively longer PSA-progression-free survival (PSA-PFS; 2.5 months vs 1.2 months, P = 0.027; 3.3 months vs 1.2 months, P = 0.017; respectively). This study introduces the PD-1 inhibitor plus anlotinib as a late-line therapeutic strategy for terminal mCRPC. PD-1 inhibitor plus anlotinib may be a new treatment choice for terminal mCRPC patients with DDR or HRR pathway defects and requires further investigation.

The twenty-first century has already recorded more than ten major epidemics or pandemics of viral disease, including the devastating COVID-19. Novel effective antivirals with broad-spectrum coverage are urgently needed. Herein, we reported a novel broad-spectrum antiviral compound PAC5. Oral administration of PAC5 eliminated HBV cccDNA and reduced the large antigen load in distinct mouse models of HBV infection. Strikingly, oral administration of PAC5 in a hamster model of SARS-CoV-2 omicron (BA.1) infection significantly decreases viral loads and attenuates lung inflammation. Mechanistically, PAC5 binds to a pocket near Asp49 in the RNA recognition motif of hnRNPA2B1. PAC5-bound hnRNPA2B1 is extensively activated and translocated to the cytoplasm where it initiates the TBK1-IRF3 pathway, leading to the production of type I IFNs with antiviral activity. Our results indicate that PAC5 is a novel small-molecule agonist of hnRNPA2B1, which may have a role in dealing with emerging infectious diseases now and in the future.
