Objective To investigate the effect and safety of Sintilimab combined with Endostar injection in the treatment of programmed cell death ligand-1(PD-L1)positive lung squamous cell carcinoma(LSCC)in elderly patients.Methods A total of 94 elderly patients with PD-L1 positive LSCC diagnosed and treated from November 2019 to November 2021 were selected as the research subjects,and they were divided into the observation group(n=47)and the control group(n=47)by random number table method.The observation group was treated with Sintilimab combined with Endostar injection,and the control group was treated with Sintilimab.Twenty-one days constituted one treatment cycle,and they were treated for 3 consecutive cycles.The clinical efficacy and improvement rate of Karnofsky performance status(KPS)score in the two groups were statistically analyzed,as well as the tumor markers[carcinoembryonic antigen(CEA),cancer antigen 125(CA125),cytokeratin 19 fragment(CYFRA21-1)],angiogenesis factors[endostatin,insulin-like growth factor-1(IGF-1),vascular endothelial growth factor(VEGF),basic fibroblast growth factor(bFGF),and platelet-derived growth factor(PDGF)],apoptosis factor[B-cell lymphoma-2 gene(Bcl-2),Bcl-2-associated X protein(Bax),Livin protein,programmed cell death 5(PDCD5)]before and after treatment.The toxic and side effects during treatment,progression-free survival(PFS)and median survival time at 2-year follow-up were compared between the two groups.Results After treatment,the objective remission rate and disease control rate of the observation group were higher than those of the control group(P<0.01);after treatment,the improvement rate of KPS score in the observation group was higher than that in the control group(P<0.01).After treatment,the levels of serum CEA,CA125,and CYFRA21-1 in both groups decreased,and which were lower in the observation group than in the control group(P<0.05,P<0.01).After treatment,the levels of endostatin increased in both groups,while IGF-1,VEGF,bFGF,and PDGF decreased;the levels of endostatin in the observation group were higher than those in the control group,while the levels of IGF-1,VEGF,bFGF,and PDGF were lower than those in the control group(P<0.05,P<0.01).After treatment,the levels of Bcl-2 and Livin decreased in both groups,while Bax and PDCD5 increased;the levels of Bcl-2 and Livin in the observation group were lower than those in the control group,while the levels of Bax and PDCD5 were higher than those in the control group(P<0.05,P<0.01).There was no significant difference in toxic and side effects between the two groups during treatment(P>0.05).The 2-year survival rate and median survival time of the observation group were higher or longer than those of the control group(P<0.05).Conclusion The treatment of PD-L1 positive LSCC in elderly patients with Sintilimab combined with Endostar injection can improve the therapeutic effect and the survival status of patients,inhibit tumor angiogenesis,induce tumor apoptosis,prolong the survival time of patients,and has good safety.

Urinary incontinence is a common complication following robot-assisted radical prostatectomy (RARP). Urethral length has been identified as a factor affecting postoperative continence recovery. In this meta-analysis, we examined the association between use of the maximal urethral length preservation (MULP) technique and postoperative urinary continence in patients undergoing RARP. We conducted a comprehensive search of PubMed, Web of Science, Embase, and the Cochrane Library up to December 31, 2023. The quality of the literature was assessed using the Newcastle-Ottawa Scale. A random-effects meta-analysis was performed to synthesize data and calculate the odds ratio (OR) from eligible studies on continence and MULP. Six studies involving 1869 patients met the eligibility criteria. MULP was positively associated with both early continence (1 month after RARP; Z = 3.62, P = 0.003, OR = 3.10, 95% confidence interval [CI]: 1.68-5.73) and late continence (12 months after RARP; Z = 2.34, P = 0.019, OR = 2.10, 95% CI: 1.13-3.90). Oncological outcomes indicated that MULP did not increase the overall positive surgical margin rate or the positive surgical margin status at the prostate apex (both P > 0.05). In conclusion, the use of the MULP technique in RARP significantly improved both early and late postoperative continence outcomes without compromising oncological outcomes.

Migratory birds are found worldwide.These birds are natural carriers of pathogens,because of their long-distance mi-grations across different climatic and geographic regions.The pathogens carried by migratory birds can enter ecosystems along migra-tory routes through direct and indirect contact between animal hosts,thereby potentially threatening the health of local poultry and even humans.Herein,we systematically analyzed evidence of pathogen spillover between migratory birds and poultry,and summa-rized the three modes of long-distance pathogen transmission by migratory birds(internal carriage,surface carriage,and environmen-tal contamination),as well as the two pathways of pathogen spillover between migratory birds and poultry(direct contact and indirect contact).Furthermore,this study proposes a multi-tiered mitigation strategy,grounded in the One Health framework,for targeting animal-environment-human interfaces to decrease the pathogen transmission risks associated with migratory birds.Key interventions include establishing an early-warning surveillance system for migratory flyways,enhancing biosecurity protocols in poultry production systems,and developing cross-regional risk assessment models for pathogen spread.Our findings provide critical theoretical founda-tions and empirical evidence for preventing zoonotic disease emergence and safeguarding sustainable poultry production.This inte-grated approach advances the coordinated development of biosafety measures and global health security.

Globally,emerging zoonotic diseases have revealed the close links among human,animal and environmental health,and the difficulties in addressing such complex health problems through a single entity.The concept of One Health has emerged,emphasizing the common strength of cross-sectoral,multidisciplinary,and social participation in addressing global health threats from a holistic perspective.China's action to address emerging infectious diseases since 2020 are reviewed,and the current status of and challenges in China's One Health governance of emerging infectious disease prevention and control systems are analyzed and summarized.The outlook for the development of a One Health governance system to help prepare for future pandemic diseases is also discussed.

Objective To investigate the clinical efficacy and safety of the combination therapy of multi-targeted small molecule tyrosine kinase inhibitors(MTKIs)with immune checkpoint inhibitors(ICIs)for late-stage solid tumor in the patients with failed standard treatment regimens.Methods The patients with advanced solid tumors who had been hospitalized in our hospital from January 2021 to January 2023 after failure of≥2 standard treatment regimens were selected and treated with MTKIs combined with ICIs.The efficacy and safety of this regimen were retrospectively studied.Results A total of 21 patients were included.As of March 1,2022,the overall popula-tion had an ORR of 38%,a DCR of 67%,a median progression free survival(mPFS)of 10 months,and a median survival(mOS)of 15 months.Common adverse reactions were pneumonia and oral ulcers.Conclusion For the patients with advanced solid tumors who have failed standard treatment,MTKIs combined with ICIs may be a treat-ment option,but prospective studies with a larger sample size are needed to confirm the efficacy and safety of this combination therapy and to explore the population most likely to benefit from this treatment method.

Patients with operable non-small cell lung cancer (NSCLC) receiving neoadjuvant or adjuvant chemotherapy have a very limited improvement in 5-year survival rate. Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI) have made a breakthrough in the treatment of EGFR-mutant advanced NSCLC, which shed light for the exploration of perioperative targeted therapy in NSCLC patients. Significant progress has been made in the research of targeted therapy of the first and third generation EGFR-TKI in perioperative patients. The availability of novel potent and less toxic targeted therapy has brought new treatments for the operable NSCLC. This article reviews the progress and existing problems of adjuvant and neoadjuvant targeted therapy in NSCLC harboring EGFR mutation.
