OBJECTIVE: To study the antineoplastic mechanism of Pingfei Mixture. METHODS: Thirty C57BL mice bearing Lewis pulmonary carcinoma were randomly divided into 3 groups: saline control group, Pingfei Mixture group and cisplatin group. Fifteen days later, tumor tissues and spleens were taken out and made into unicellular suspension. Argyrophil staining was taken to carcinoma cells and cultured T cells. KL-2 style cell image analysis system was used to analyze the rate between AgNORs and nuclear region (I.S). RESULTS: There were dense brownish-black granules in tumor cell nuclear of saline control group. The brownish-black granules of Pingfei Mixture group and cisplatin group were less than those of saline control group. The differences of T cell I.S in these three groups were significant. The I.S of Pingfei Mixture was higher than that of the other groups, and the I.S of the cisplatin group was the lowest. CONCLUSION: Pingfei Mixture can inhibit tumor cell proliferation, although the effect is inferior to cisplatin. Pingfei Mixture can also promote T cell proliferation and its effect was superior to cisplatin.

There lack scientific methods for evaluating the treatment of cancer pain with external therapies of traditional Chinese medicine (TCM). The level of clinical study in this field needs to be improved. The authors assert that when external therapies of TCM are applied to treat cancer pain, different types of cancer pain should be distinguished and treatment should be applied according to such a differentiation. Under this framework scientific evaluation can be conducted. The authors also assert that the findings of randomized, blinded and controlled trials should be given particular attention, and it is necessary to include titration of morphine into clinical trails of external therapies for the treatment of cancer pain, not only complying with the three-ladder principle for treating cancer pain suggested by the World Health Organization, but also not influencing the effect evaluation of external therapies of TCM on cancer pain. Patient diaries recording pain were revised as observation indexes. The primary indicator of efficacy was the pain intensity score and the secondary indicators were the equivalent of morphine and the remission rate of pain. The time to onset, remission duration and comparison of assessment of pain influence can mirror the characteristics of external therapies of TCM on cancer pain.

Objective To study the effect of elemene on transcription factor ELK1 and its target gene in human cervix cancer Hela cell. Methods The cell proliferation was assessed by MTT assay. The luciferase activity of transcription factor ELK1 was determined by the Dual-Luciferase Reporter Assay System. The protein expression of phosphorated ELK1 and its target gene c-fos were determined by Western Blot. Results Elemene can remarkably inhibited the growth of Hela cell and its IC50 was 80.6 ?g/mL. The luciferase activity of transcription factor ELK1 in Hela cells treated with elemene was inhibited. The protein expression of phosphorated ELK1 and its target gene c-fos in Hela cells treated with elemene were down-regulated. Conclusion Elemene can inhibit human cervix cancer Hela cell proliferation,which may be related with suppression of c-fos gene through inhibiting expression of phosphorated ELK1.

Objective To observe the clinical efficacy of applying Sweat Reduction Formula (SRF) externally in the treatment of cancer-linked hyperhidrosis. Methods 45 tumor patients, who exhibited excessive perspiration, were selected and recruited randomly into an experimental group (Sweat Reduction Formula group) with 24 patients in it and a control group (Placebo group) with 21 patients in it. The experimental group was treated with SRF and the control group was administrated with placebo. Neuropad diagnostic patches were used to observe the period of time that required for any visual changes in color before and after medication. These observations were then matched with the commonly seen signs and symptoms scoring table, to evaluate the changes of symptoms and KPS. Results The color changing time of the experimental group was 14.45±3.91 min. and 19.51±5.30 min. before and after medications respectively. And the changing time in the control group was 13.49±4.96 min. After medication. The results were highly significant with P<0.05. There were also different levels of significant improvements in terms of spontaneous perspiration, night sweating, dry mouth, feverish sensation over hand-foot centers and body, aversion to cold etc after the treatment in the experimental group. Conclusion It would be more objective to evaluate the clinical efficacy of applying SRF on navel to treat cancer-linked hyperhidrosis with neuropad diagnostic patches.

Objective To analyze the dose rate effect and potentially lethal damage repair in DNA double strand break repair deficient murine cells (SCID) irradiated by ? ray. Methods The wild type(CB.17+/+) and SCID cells were exposed to ? ray at high and low dose rates. The high dose rate exposure was fractionated into two equal doses at 24?h intervals. The survival rates of irradiated cells were calculated by clony forming analysis. Results When ? ray was given to wild type(CB.17+/+) cells in two fractions at 24?h intervals, the survival rate was significantly higher than that when the same total dose was given singly. In contrast, there was no difference in the survival rates between the single and fractionated exposure in SCID cells. SCID cells were more sensitive than CB.17+/+ cells to both low and high dose rates ? ray exposure for cell killing. The survival rate by low dose rate exposure was significantly higher than that by high dose rate exposure, not only in CB.17+/+ cells but also in SCID cells. Conclusions SCID cells are deficient in repairing ? ray induced double strand breaks. There is dose rate effect in both SCID and CB.17+/+ cells.

BACKGROUND:Regulatory T cels (Treg) are classified into two subsets, nature Treg (nTreg) and induced Treg (iTreg). Although there is consensus that CD4+CD25+FoxP3+CD127-is the widely accepted phenotype of Treg, it remains unclear what is the difference in phenotypes including cytokine patterns of nTreg and iTreg. OBJECTIVE:To understand and compare the plasticity of nTreg and iTreg and to search the exact mechanism of cytokine secretion in Tregs. METHODS: We investigated the frequency and cytokine pattern of CD4+CD25+FoxP3+CD127-nTreg in freshly separated peripheral blood mononuclear cels of five healthy individuals using 8-color fluorescence flow cytometry (FACSCanto II). Subsequently, after 9 days of alostimulation in mixed lymphocytes, the frequency and cytokine pattern of CD4+CD25+FoxP3+CD127-iTreg were determined and analyzed. RESULTS AND CONCLUSION:In fresh cels, (1.5±0.70)% of CD4+ T cels were CD4+CD25+FoxP3+CD127- nTregs. Almost al these cels expressed interferon (IFN)-γ-, interleukin (IL)-2- or transforming growth factor-β+, and partial cels expressed IL-10+ or IL-10-. After 9-day alostimulation, the number of CD4+CD25+FoxP3+CD127- iTreg expressing IFN-γ+, IL-2-, IL-2+, IL-10+ or TGF-β+increased strongly. The main subsets of human nTregs were CD4+CD25+FoxP3+CD127-IFN-γ-IL-2-IL-10+TGF-β+and CD4+CD25+FoxP3+CD127-IFN-γ-IL-2-IL-10-TGF-β+ T cels. The proportion of each subset in CD4+ T cels was (1.1±0.59)% and (0.39±0.16)%, respectively. Whereas the main subsets of human iTregs were CD4+CD25+FoxP3+CD127-IFN-γ+IL-2-IL-10+TGF-β+ and CD4+CD25+FoxP3+CD127-IFN-γ+IL-2+IL-10+TGF-β+. Human nTregs were characterized as IFN-γ-IL-2- double negative, producing IL-10 and TGF-β or only TGF-β without IL-10, and not proliferatingin vitro. During the alostimulation in mixed lymphocytes, IFN-γ+ iTregs proliferated remarkably. One-third of IFN-γ+ iTreg expressed IL-2+, and two-thirds of IFN-γ+ iTregs expressed IL-2, both of which produce IL-2 and TGF-β. Our results imply that CD4+CD25+FoxP3+CD127- Treg are potentialy immunosuppressive probably because of their mandatory TGF-β and optional IL-10 production.
