Using a syngeneic transplantable leukemia model of 615 inbred mice, named L615, we (1) compared the adoptive immunoprophylactic(AIP) effects of spleen cells from various normal dornor mice with different genetic background and from different immune-deficient mice;(2) studied the adoptive immunotherapeutic (AIT) and adoptive chemo-immunotherapeutic(ACIT) effects of immune spleen cells from those survival mice in the AIP groups;(3) analysed the antitumor activities of various murine spleen cells either nonspecifically activated in vitro or specifically induced in vivo and resensitized in vitro by MMC-treated L615 tumor cell vaccine (TCV).Our results might provide some new experimental evidences for clinical application of cancer ACI.

The result showed that CD3AK induced and expanded in vitro could kill MHC I class - negative K562 (NK - sensitive) and Daudi (NK - resistant) tumor cells in a MHC - nonrestricted manner. Induction of necrosis and / or apoptosis of target cells were responsible for the tumorlytic effect mediated by CD3AK.

This essay investigated the in vitro tumoricidal activity of Con A primed murine LAK cells (Con A-LAK), discussed the role of mTNF-? in the killing effect. The results showed that Con A-LAK cells could kill NK sensitive YAC-1, TNF sensitive L929 and H-2 low/non expression HCa-F target cells; The cytotoxicitity of Con A-LAK cells was performed by direct contact, the non-secretary pathway mediated by interaction of surface ligands of effector cells and receptors of target cells play an important role; Con A-LAK cells expressed mTNF-?, which participated in the killing of TNF sensitive tumor cells and might be one of the important effector molecules in MHC non-restricted, antigen non-specific cvtotoxicitv.

This article summarized clinical studies and mechanism research literature on acupuncture in treating chemotherapy induced nausea and vomiting in the latest 20 years. It found that the domestic and foreign researches tend to regard acupuncture as an effective method for the treatment of chemotherapy induced nausea and vomiting, which still requires further high-level clinical researches to verify. Acupuncture may prevent and treat chemotherapy induced nausea and vomiting through multiple mechanisms, and studies on these mechanisms show extensive research prospect.

Objective:To find out the role of JNK/SAPK signaling-transduction pathway in the effect of elemene against hepatocarcinoma, offering the clue to ilustrate the molecular mechanisms of antitumor effects of elemene. Methods: The detection of the distribution of elemene in Hca-F cells was detected by gas chomatography and apoptotic changes in elemene treated. SMMC7721 cells were examined by TEM. After elemene treatment, the activation of JNK/SAPK in HepG2 cellls and the DAXX gene expression in SMMC7721 cells were detected by Western blotting and RT-PCR respectively. Results: Gas chomatography showed that elemene was detected at 8. 42 minute. The SMMMC7721 cells treated by elemene for 3 hours began to show typical apoptotic changes . The JNK/SAPK activity in HepG2 cell treated with heat shock was the highest of all groups and the group treated with elemene was the next and the control group is the lowest one. There was no DAXX gene expression in SMMC7721 cells treated with elemene. Conclusion: Elemene can diffuse into cells. Tumor cell apoptosis treated with elemene may be induced by JNK/SAPK activating and DAXX signal pathway may not play key role in JNK/SAPK activation induced by elemene.
