The promulgation of regulations of coping with public health affairs outbreak bring the prevention and cure of atypicalpneumonia into a legal system, and it has an important meaning of overcoming the atypicalpneumonia. In order to cope with all kinds of public health affairs outbreak more effectively, we must perfect the public health legal system, establish scientific system of meeting emergency, strengthen the popularization and education of legal knowledge, and enhance the whole social consciousness of prevention epidemic diseases by law.

Background and purpose:Cytokine-induced killer (CIK) has both the advantages of T lympho-cytes’ powerful anti-tumor activity and NK cells’ tumor killing capacity without MHC restriction. It could directly kill tumor cells, regulate and enhance immune function, without damaging the structure and functions of the immune sys-tem. Its effects on the treatment of malignant solid tumors has been widely recognized. This study aimed to evaluate the anti-proliferation effects of CIK cells obtained and cultivated from lung cancer patients’ lymph nodes. Meanwhile, the safety of clinical transfusion was observed.Methods:The peripheral blood and lymph nodes of 6 surgery patients with lung cancer from Shanghai Chest Hospital were used to cultivate CIK cells for 14 days. The phenotypes of CIK cells were detected by lfow cytometry. The anti-proliferation activities of CIK cells on A549 lung cancer cells were detected by CCK8 assay. The morphological changes of CIK cells were observed by invert microscope. The expression of CEA level and adverse events were evaluated after CIK transfusion.Results:The proportion of CD3+CD56+T lymphocyte in two groups were both more than 30%. The CCK8 assay showed that the suppression rate of lymph nodes group was higher than that of peripheral blood group at each effect/target ratio(P<0.05). The adverse effect of CIK transfusion was mild and tolerable. The expression of CEA level decreased in patients.Conclusion:Lymph nodes of surgery patients with lung cancer can be used for cultivation of CIK cells. The anti-tumor activity of CIK isolated from lymph nodes is better than that of CIK cells cultivated from peripheral blood. Preclinical experiments showed high safety.

Background and purpose:Checkpiont targeted immunotherapy in the field of solid tumor therapy has huge potential, triggering a boom in the study of immune targeted drugs. A study has provided a basis for the follow-up study of ipilimumab combined with chemotherapy in the treatment of non-small cell lung cancer(NSCLC) patients. This study counted the adverse event statistics that ipilimumab or placebo combined with paclitaxel and carboplatin as first-line therapy for the treatment of stage Ⅳ or recurrent squamous cell carcinoma to evaluate the safety of ipilimumab combined with chemotherapy in the treatment of advanced squamous cell carcinoma.Methods:This study selected 13 patients with ECOG scores≤1 and stage ⅣA or ⅣB squamous cell carcinoma in the Shanghai Chest Hospital, Shanghai Jiao Tong Uni-versity. Randomized controlled double blind trial was used in this study. The patients of experimental group were treated with ipilimumab combined with paclitaxel and carboplatin, while the patients of control group were treated with the placebo combined with paclitaxel and carboplatin. Adverse events (AEs) were counted in the process of treatment.Results:The most common AEs were the 1/2 grade AEs. Immune-related AEs (irAEs) reported in the ipilimumab group included level Ⅰ of diarrhea and pruritus, level Ⅱ of rash and pruritus and level Ⅲ of hypophysitis.Conclusion:The side effects of ipilimumab were mild, tolerable and manageable.
