The present application relates to the technical field of online car-hailing risk control, and particularly relates to a method for implementing an online car-hailing pick-up and drop-off abnormality risk control dynamic rule engine based on flink CEP. In the online car-hailing service, after a passenger issues an order on a mobile phone, the driver is affected by external environmental factors, vehicle condition factors, other human factors and complex environments during the process of picking up and dropping off the passenger, which may result in a variety of abnormal situations such as pick-up timeout, driver driving in the opposite direction, driver not moving and the like. A related risk control system is established in each service system. The present application uses mysql to dynamically load rules to ensure the dynamic scalability of the rules, and uses flink CEP to calculate the rules to ensure the timeliness and accuracy of the calculation results. The overall scheme supports the timeliness and dynamic scalability requirements of abnormal indicators in the risk control system under the premise of not stopping service when the rules are changed.

The invention provides a fusion gene and an HPV nucleic acid vaccine. A fusion gene is obtained through research and optimization, and the fusion gene is obtained by sequentially connecting an L1 gene of an HPV 16 type, an E5 gene, an E6 gene and an E7 gene of the HPV 16 type and an E5 gene, an E6 gene and an E7 gene of an HPV 52 type. The inventor finds that an HPV vaccine prepared by taking the fusion gene as an antigen component can effectively promote cellular immune response and formation of long-term protective memory, promote hair growth center response and formation of humoral immune memory, remarkably improve the proportion of NKT cells, successfully activate systemic anti-tumor cell immune response of mice, and improve the anti-tumor effect of the mice. The anti-tumor immune effect is greatly improved. The traditional Chinese medicine composition has the dual effects of prevention and treatment, has the prevention capability, can effectively inhibit tumor growth and has the tumor treatment capability. The HPV vaccine also has the advantages of high safety, good stability and the like, and has a wide application prospect.
