  • PROGRESS OF OSTEOSARCOMA THERAPY

    Objective To review the research progress of the treatment of osteosarcoma, and to thoroughly understand its current state of research and prospect so as to lay a sol id foundation for the cl inical treatment. Methods The cl inical and experimental research l iteratures about treatment of osteosarcoma were extensively reviewed and analyzed. Results The present treatment of osteosarcoma is still need to comprehensive therapy which combine chemotherapy and surgical treatment. There are some progresses in gene therapy and molecular targeting therapy which can improve survival rate. Furthermore, well-designed studies and cl inical trials are needed to evaluate the potential therapeutic impact before they are used in cl inical. Conclusion Advancement in chemotherapeutic regimens has improved survival and l imb-sparing surgery in the treatment of osteosarcoma, but the progress of gene therapy and molecular targeting therapy gives new hope for osteosarcoma patients.

  • Advances in targeted blocking of angiotensin-converting enzyme 2 receptor for prevention of SARS-CoV-2 infection

    Vaccines and antibodies are currently effective intervention strategies for preventing and treating COVID-19. Angiotensin-converting enzyme 2 (ACE2), a primary binding receptor for SARS-CoV-2, is a potential target for the prevention and treatment of COVID-19. At present, therapeutics based on the strategies that block the binding of SARS-CoV-2 Spike protein to the ACE2 receptor have entered clinical trials. On December 5, 2022, the journal Nature published the results of a pharmacological intervention to downregulate ACE2 expression for prevention of SARS-CoV-2 infections. The study found that a nuclear receptor, farnesoid X receptor for bile acids, regulated ACE2 expression. The clinical drug ursodeoxycholic acid that was used to treat liver diseases could downregulate ACE2 expression and prevent SARS-CoV-2 infections, showing a new potential pathway in managing COVID-19.

  • Research progress on KRAS mutation in pancreatic tumorigenesis and pancreatic cancer therapy

    ObjectiveTo summarize the research progress of KRAS mutation in pancreatic tumorigenesis and therapy.MethodThe research progress of KRAS mutation in pancreatic tumorigenesis and therapy were summarized by reading the domestic and international literatures published in recent years.ResultsPancreatic cancer had the title of " king of cancer”. More than 90% of pancreatic cancer patients had KRAS mutation. KRAS had a complex relationship with pancreatic cancer through downstream signaling pathways, including Raf (rapidly accelerated fibrosarcoma)-mitogen-activated protein kinase kinase (MEK)-extracellular signal-regulated kinase (ERK), phosphatidylinositol-4, 5-bisphosphate 3-kinase (PI3K)-protein kinase B (AKT), and RalGDS-Ral. Although basic research on pancreatic cancer was deepening, there was still a lack of effective molecular targeted drugs.ConclusionsKRASgene plays an important role in the occurrence of pancreatic cancer. The treatment associated with KRAS mutation provides a more effective prognostic possibility for pancreatic cancer patients.

  • Meta-analysis of Anti-Vascular Endothelial Growth Factor Agents Therapy for Advanced Renal Cell Carcinoma

    Objective To evaluate the efficacy and safety of anti-vascular endothelial growth factor (VEGF) agents for advanced renal cell carcinoma. Methods We searched MEDLINE, EMbase, The Cochrane Library, CBMdisc and China Academic Periodical database from the establishment of each database to April 2009. We included randomized controlled trials (RCTs) that evaluated anti-VEGF agents (sunitinib, sorafenib and bevacizumab). The quality of the included trials was evaluated by two reviewers independently. Meta-analyses were conducted by the Cochrane Collaboration’s RevMan 4.2 software. Results Four RCTs involving 2 320 patients were identified. According to the different interventions for advanced renal cell carcinoma, we divided the patients into two groups: anti-VEGF agents monotherapy and anti-VEGF agents plus interferon combination treatment. Our meta-analyses showed: monotherapy was superior to interferon on inhibition of tumor progression [OR=0.38, 95%CI (0.29, 0.51), Plt;0.01] and control of tumor [OR=2.53, 95%CI (1.87, 3.43), Plt;0.01], but was not significantly different from interferon on the overall effective rate [OR=1.97, 95%CI (0.20, 19.57), P=0.56] and serious side effects [OR=1.98, 95%CI (0.90, 4.34), P=0.09]. There were significant differences between anti-VEGF agents plus interferon and interferon alone on inhibition of tumor progression [OR=0.67, 95%CI (0.53, 0.84), P=0.000 5], overall effective rate [OR=2.65, 95%CI (1.94, 3.61), Plt;0.01], control of tumor [OR=2.14, 95%CI (1.65, 2.78), Plt;0.01] and serious side effects [OR=2.63, 95%CI (2.09, 3.31), Plt;0.01]. Conclusion Compared with interferon, anti-VEGF agents could inhibit tumor progression more effectively. Moreover, the combination therapy with interferon could offer a more favorable overall effective rate for advanced renal cell carcinoma, but then followed by more serious side effects. We need to weigh the merits and demerits of drugs before making a clinical decision for advanced renal cell carcinoma.

  • Research progress on drug therapy for metastatic colorectal cancer

    Objective To understand the latest research progress of chemotherapy, targeted therapy and immunotherapy drugs in the treatment of metastatic colorectal cancer. Method The literature on the efficacy of different treatment drugs for metastatic colorectal cancer in recent years both domestically and internationally was retrieved and reviewed. Results There had been many clinical research progress in the treatment of metastatic colorectal cancer, new drugs had emerged, targeted drugs were particularly prominent, and more trials of therapeutic drugs and drug combination treatment regimens were also being carried out. Different treatment methods were applied to patients according to the mutation status of RAS/RAF and the expression of mismatch repair protein, the survival benefit varied greatly. Conclusion Precision medicine is becoming increasingly important, screening patients to choose appropriate treatment modality can further improve survival benefit.

  • 葡萄膜黑色素瘤抗血管生成靶向治疗的研究进展

    放射治疗、手术切除、经瞳孔温热疗法、巩膜敷贴治疗、化学药物治疗、免疫治疗等单独或联合应用对改善葡萄膜黑色素瘤(UM)患者生存率无明显差异。抗血管内皮生长因子(VEGF)抑制剂等抗血管生成靶向治疗与化学药物治疗、放射治疗等联合应用可明显提高疗效。但单独使用抗VEGF治疗UM效果并不理想, 而且还存在VEGF抑制剂导致肿瘤形成和转移播散的风险。虽然UM的抗血管生成靶向治疗取得了一些进展, 但是离真正的临床应用还有相当长的距离。需要进一步加强对UM的发病机制研究, 特别是UM新生血管发生发展机制方面的研究, 探索可能的干预靶点; 同时加强UM的转化医学研究, 筛选靶向治疗UM的新药物、新方法。
