Objective To observe the effectiveness and safety of Kang′ai injection combined with docetaxel or gemcitabine chemotherapy in treatment of elderly patients with advanced non-small cell lung cancer(NSCLC). Methods A multi-center,randomized and parallel control study was carried out in 150 elderly patients with ad-vanced NSCLC treated in 3 hospitals during the period from June 2013 to August 2014.The patients were randomly divided into platinum-based group(platinum-based doublet chemotherapy)and Kang′ai group(Kang′ai injection combined with single agent chemotherapy). The clinical efficacy,quality of life and adverse reactions were ob-served and compared between the two groups. Results There was no significant difference in the disease control rate between the two groups group(79.66% vs 81.82%)(χ2=0.101,P=0.751)while the effective rate of Kang′ai group was significantly higher than that of platinum-based group(30.51% vs 14.29%)(χ2=5.240,P=0.022). The effective rate of clinical symptom relief in Kang′ai group after treatment was significantly higher than that in platinum-based group(69.49% vs 48.05%)(χ2=6.278,P=0.012),and the increase rate of PS score in Kang′ai group after the treatment was also significantly higher than that in platinum-based group(18.64% vs 3.90%)(χ2=7.868,P=0.005).There was no significant difference in quality of life between two groups(P>0.05).The quali-ty of life score of Kang′ai group was significantly higher than that of platinum-based group at the second course of treatment(P<0.05).The incidence of adverse reactions in Kang′ai group was significantly lower than that in the platinum-based group(47.46% vs 71.42%)(χ2= 8.070,P < 0.05). Conclusion Kang′ai injection combined with single agent chemotherapy can effectively relieve clinical symptoms and reduce the tumor size in elderly patients with advanced NSCLC,with high safety.

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.
