Chinese Journal of Biologicals 2024;37(5):627-633
COVID-19 is a respiratory disease caused by SARS-CoV-2 infection,which has strong infectivity and seriously threatens human health all over the world. Vaccination is the most effective means to prevent SARS-CoV-2 infection. World Health Organization(WHO)has required the use of Global Standard 1(GS1)for the tracking and traceability of COVID-19vaccines and therapeutics. Traceability identification system is the basis and core of traceability system,as well as the premise of implementation of traceability,throughout the whole product traceability process. By carrying out unique global coding for all levels of packaging and logistics units of export vaccine products,and establishing vaccine traceability codes and logistics unit traceability codes,we can help export vaccine manufacturers establish traceability systems,realize the traceability of product information in production,circulation,use and other links,strengthen the quality and safety supervision of export vaccine products,strengthen the risk monitoring,early warning and effective disposal,as well as strengthen the recall of defective products and analysis of causes,so as to enhance the international market's trust and recognition of Chinese vaccine safety. This paper summarizes the importance of establishing traceability system for export vaccine products,the application of GS1 system in medical field at home and abroad,the traceability identification coding,barcode representation and quality requirements of export vaccine products,in order to provide a reference for establishing traceability identification system for export vaccine products in China and meeting the requirements of international standards and regulations.

Objective To study the analysis of non-small cell lung cancer patients with multiple brain metastases with erlotinib combined with whole brain radiation therapy clinical observation and effect of C on vascular endothelial growth factor level. Methods 40 cases of non - small cell lung cancer patients with multiple brain metastases treated in Taizhou tumor hospital from January 2015 to April 2016 were selected and randomly divided into the control group and the experimental group, with 20 patients in each group. The control group and the experimental group patients were given clinical treatment of whole brain radiotherapy, the control group was given routine treatment, the experimental group received erlotinib. The clinical effects of the 2 groups were compared and analyzed. Results After the corresponding treatment, the experimental group of 20 patients, 8 cases of complete remission, 7 cases of partial remission, the number of effective treatment for 15 cases, the treatment rate was 75.0%. Of the patients in the control group, 6patients had complete remission, and 4 patients had partial remission. The effective rate was 50%. Available, the effective rate of the treatment group (75.0%) was significantly higher than that of the control group (50.0%), with statistical difference (P<0.05). The survival rate of the experimental group after one year (80.0%) was significantly higher than that of the control group (60.0%), with statistical difference (P<0.05). The level of vascular endothelial growth factor (C) in the experimental group was significantly lower than that in the control group (P<0.05). Conclusion Non small cell lung cancer patients with multiple brain metastases with erlotinib combined with radiotherapy in the clinical treatment effect of whole brain is better, can improve the survival rate in a large extent, improve the endothelial growth factor C levels, with the further promotion of the clinical significance.
