RESUMO
Non-small cell lung cancer （NSCLC） is a malignant tumor of the respiratory system with a high incidence. The early symptoms are not typical， and most patients are diagnosed at an advanced stage， which seriously threatens the lives and health of people. Surgery， chemotherapy， and targeted therapy are the main means of treatment at present， but the consequent drug resistance and adverse reactions restrict these treatment methods with certain limitations. In recent years， with the development of traditional Chinese medicine （TCM） in tumor resistance， TCM has attracted extensive attention for its obvious therapeutic effect and fewer adverse reactions. Numerous signaling pathways are involved in the formation and development of NSCLC， where phosphatidylinositol 3 kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway is one of the key regulatory pathways. The PI3K/Akt/mTOR signaling pathway affects the proliferation， invasion， and metastasis of NSCLC cells by affecting the cycle， inhibiting the apoptosis， inhibiting the autophagy of tumor cells， and promoting tumor neovascularization. As revealed by the recent literature， Chinese medicine plays an indispensable role in NSCLC cell autophagy， cell cycle， apoptosis， invasion and metastasis， neovascularization， and reversal of drug resistance by regulating the PI3K/Akt/mTOR signaling pathway. Although some Chinese medicinal extracts or compounds have made great breakthroughs in some mechanisms of action in the treatment of NSCLC， these studies only remain at the level of in vitro cell experiments and animal studies in vivo. Researchers are faced with the great challenge of "transforming the research results of Chinese medicines into clinical applications". Based on the current research status in China and abroad， this paper reviewed Chinese medicine in the intervention in NSCLC through the regulation of PI3K/Akt/mTOR signaling pathway in recent years， in order to open up new ideas for NSCLC drug therapy research and also provide a useful reference for further mechanism research.
RESUMO
Pro-inflammatory cytokines selectively induce specific signals to regulate host responses. Since the immunological imbalance caused by abnormal release of cytokines is involved in the development of many diseases, cytokine-specific detections are of great clinical significance for disease diagnosis and efficacy monitoring. Aptamers are single-stranded nucleic acid sequences which can bind to the target with high selectivity and affinity. It has attracted much attention in the development of novel aptamers-based methods for the detection of specific biomarkers of inflammatory diseases. This paper reviewed recent advances in electrochemical and optical aptasensors for the detection of tumor necrosis factor-α, interleukin-6, transforming growth factor-β, interferon-γ and interleukin-8. The findings offered valuable insights into the clinical application potential and challenges of nucleic acid aptamers in the detection of key inflammatory cytokines, providing a meaningful reference for the development of aptamer-based cytokines sensitive detection point-of-care testing equipment and novel diagnostic strategies for inflammatory disorders.
RESUMO
Objective To observe the therapeutic efficacy of bronchial artery embolization(BAE) and pulmonary artery embolism(PAE) for massive hemoptysis.Methods 48 cases with massive hemoptysis were treated with embolization,of them,43 underwent selective bronchial arteriography and BAE with microballoon of Baiji,three cases underwent selective bronchial arteriography and treated with PAE at the same time,two cases underwent PAE.Results The abnormal features of arteriography were displayed in all hemoptysis stopped after operation 48 h later.Three cases recurred during followed up six months later,but the hemoptysis decreased.Conclusion Pulmonary arteriography and PAE therapy should be preformed when BAE fails for massive hemoptysis.
RESUMO
Objective To evaluate the therapeutic effect of pulmonary carcinoma by bronchical arterial infusion (BAI) and bronchical arterial infusion with the addition of pulmonary arterial infusion (PAI).Methods Totally 69 cases with pulmonany cancinoma were treated by intervention therapy .Of them ,38 cases were undergone the bronchical arteriography and arterial infusion and 31 cases were undergone the brochical pulmonany arterial dual infusion.Results The bronchical arteryies taken part in the blood supply of neoplasmin all cases ,while the pulmonany artery only in 77% of cases .The effective ratio of BAI +PAI was 87%, and BAI was 65.7%,there were markly different (?
