To investigate the effect of Tanreqing injection on immune activity of peripheral blood lymphocytes of patients with lung cancer. The peripheral blood lymphocytes of patients with lung cancer and healthy persons were separated by the density gradient centrifugation method for subsequent experiments, with those from healthy persons as the positive control. The effect of Tanreqing injection on stimulating the proliferation of lymphocytes with phytohemagglutinin (PHA) was determined by MTT method. The effect of Tanreqing injection on the lymphocyte secretions of IFN-γ and TNF-α and the subset ratio of lymphocytes cultured separately or with Tanreqing injection of different concentrations were examined by ELISA and flow cytometry (FCM) respectively. In addition, the LDH release assay was used to detect the cytotoxicity of cytotoxic T cells (CTL) and natural killer cells (NK). According to the findings, all of immunological indexes of lymphocytes from patients with lung cancer were weaker than that of healthy persons, but with the obvious increases in proliferation activity and IFN-γ and TNF-α secretions of lymphocytes co-cultured with Tanreqing Injection (P < 0.05). Among lymphocyte subsets co-cultured with Tanreqing Injection, CD3+, CD3+ CD4+ and CD3- CD16 + 56+ cell ratios notably increased, whereas CD4+ CD25+ Treg cell ratio obviously decreased (P < 0.05). In the meantime, Tanreqing injection can markedly promote the cytotoxicities of CTL and NK (P < 0.05). In conclusion, Tanreqing injection shows a significant effect in promoting the immune activity of lymphocytes from patients with lung cancer and their anti-tumor immunity.

Under indoors simulating natural growing condition, the 4th-instar Mythimna separata larvae were fed by using poi- son leaf disk method. The effect of total ginsenosides on the protective enzymes (PPO, T-SOD, CAT and POD) of M. separata larvae was studied. The total ginsenosides could influence the protective enzymes of 4th-instar M. separata larvae significantly. After treated by total ginsenosides, the PPO activities increased firstly then decreased, and tended to equilibrium, and reached the maximum after 48 h. Furthermore, the total ginsenosides disturbed the dynamic balance of SOD, CAT and POD of M. separata larvae, and the yield of O2-* speeded. The results suggest that the total ginsenosides influence the protective enzymes of 4th-instar M. separata larvae, and disturb the original dynamic balance of protective enzymes. Consequently the insect suffers from the harm of O2-*.

Epigenetics comprises the modifications made in gene expressions without changing the DNA sequence itself. Significant epigenetic changes take place during spermatogenesis and fertilization and exert direct influences on embryogenesis. This article provides an overview of the latest researches on epigenetics of male germ cells and a brief discussion on the correlation of sperm with embryogenesis in four aspects: DNA methylation, histone modification, regulation of non-coding RNAs, and genomic imprinting.

OBJECTIVETo study the regulatory effect of Ligustrazine Injection (LI) on the cellular immune function in patients undergoing autologous blood transfusion (ABT).

METHODSEnrolled were 60 patients scheduled for receiving selective lumbar surgery at the Department of Spinal Orthopedics, First Hospital Affiliated to Guangzhou University of Traditional Chinese Medicine during October 2009 to June 2010. They were equally randomized into two groups, the trial group and the control group. LI was given to patients in the trial group by intravenous dripping at the dose of 2 mg/kg 30 min before autologous blood collection. The LI (at the final concentration of 0.005%) was added in the heparin saline solution and the washing saline for recycle blood. No LI was given to patients in the control group. They received the same treatment of the trial group. The operation time, the amount of blood loss and blood transfusion were recorded. Patients' venous blood samples were collected for determining cytokines including interleukin-2 (IL-2), interleukin-10 (IL-10), interferon-gamma (IFN-gamma) by ELISA and calculating IL-2/IL-10 ratio before surgery (T1), 1 h (T2), 1 day (T3), and 5 days (T4) after ABT.

RESULTSThere was no statistical difference in the amount of blood loss and blood transfusion, the levels of IL-2, IL-10, IFN-gamma, or IL-2/IL-10 at T1 between the two groups (P>0.05). Compared with T1 of the same group, the level of IL-2 decreased at T(2-4), IL-10 increased and IL-2/IL-10 decreased at T(2-3) in the two groups. The level of IFN-gamma decreased at T(2-4), IL-2/IL-10 increased at T4, the level of IL-10 decreased at T4 in the control group (P<0.05, P<0.01). The level of IL-10 decreased at T4 in the trial group with statistical difference (P<0.05, P<0.01). Compared with the control group, the level of IL-2, IFN-gamma, and IL-2/IL-10 at T(2-4) were obviously higher in the trial group. But the IL-10 level was lower in the trial group than in the control group at T(2-4) (P<0.05, P<0.01).

CONCLUSIONThe application of LI in ABT had regulatory effects on the balance of cytokines.
