Objective:To determine the relationship between brachia l artery blood pressure and radial artery blood pressure in children and whether blood pressure measured from the radial artery can replace blood pr essure measured from the brachial artery. Methods:Brachial and rad ial artery pressures in 105 children were measured using an electronic sphygmomanometer.Results:There was no significant difference between the average values of blood pressures of the brachial and radial arteries in the 105 children studied (P>0.05). Linear regression and correlation analyses showed that there was a positive linear correlation between the systolic pressure of the b rach ial artery and the radial artery in the 105 children, as well as a posit ive linear correlation between the diastolic pressures of the brachial and the radial arteries. Conclusion:Blood pressure values from the radial artery can completely replace blood pressure values from the brachial artery.

Resveratrol is a natural polyphenolic compound. It possesses a variety of biological properties including neuroprotective effects, cardiovascular protection, anti-inflammatory and anti-cancer effects. In recent years, the anti-tumor effects of resveratrol have attracted a lot of attention. Its anti-tumor effects may be mediated by inhibiting tumor initiation, inhibiting tumor cell proliferation, promoting tumor cell apoptosis and inhibiting tumor cell invasion.

Toll-like receptor (TLR) is an important pattem recognition receptor (PRR) which partici pates in innate immunity and regulates adaptive immunity.TLR can be expressed in immune cells and malig nant tumors recognize conservative molecular structure,mediate response of inflammation,tissue injury and repair,which plays an important role in the process of tumor.Research results about some molecules and signal pathways of TLR demonstrate that it can act anti or pro-tumor dual functions,which has an extensive prospects in prevention and treatment of tumor.

Chemokine receptor 4 (CXCR4) belongs to G protein-coupled receptor superfamily.It can induce immune cells-directed chemotaxis,thus keeping their homeostasis.CXCR4 expresses on a variety of tissues and cells.In different tumors and at different stages of tumors,CXCR4 expression is significantly higher than that in normal tissues.CXCR4 plays an important role in tumor progression since it is involved in tumor cell proliferation,adhesion,invasion and metasta.

Objective To investigate the effect of miR-27a mimic and inhibitor on proliferation and apoptosis in melanoma cell line WM239. Methods The miR-27a mimic,inhibitor and its negative control were transfected into WM239 cells. The transfection efficiency was evaluated by fluorescence microscope. The expres-sion of miR-27a was detected by real-time fluorescent quantitative PCR. The proliferation of cells was detected by MTT. The cell apoptosis and cell cycle were analyzed by flow cytometry. Results The transfection efficiency in WM239 cells was 80% to 90%. The expression of miR-27a was markedly up-regulated in miR-27a mimic group (2-△△CT value is 26. 98 ± 0. 01),with statistically significant difference(t= -1 123. 67,P=0. 00);and the miR-27a inhibitor group showed lower expression of miR-27a(2-△△CT value is 0. 96 ± 0. 02),there was no statisti-cally significant difference compared with normal control group(t=0. 04,P=0. 06). The proliferation of cells was obviously inhibited in miR-27a mimic group,and there was statistically significant difference compared with normal control group[absorbance of 72 h(0. 45 ± 0. 02)∶(0. 72 ± 0. 01),F=129. 56,P﹤0. 05]. The percent-age of WM239 cells in G0-G1 phase was increased[(74. 83 ± 1. 46)∶(63. 73 ± 1. 25),F=30. 33,P﹤0. 05], and the percentage of WM239 cells in S phase and G2-M phase were decreased[(21. 33 ± 1. 75)∶(27. 50 ± 1. 25),F=14. 98,P﹤0. 05;(3. 90 ± 1. 31)∶(8. 80 ± 2. 10),F=3. 66,P﹤0. 05]. The apoptosis rate of cells was significantly increased in miR-27a mimic group compared with normal group[(29. 67 ± 0. 91)%∶(1. 44 ± 0. 85)%,F=530. 90,P﹤0. 01],but the inhibitor group had no obvious effect on cell cycle and cell apoptosis. Conclusion MiR-27a can suppress melanoma cell proliferation and act as a tumor suppressor gene,which is rel-evant to induce cell apoptosis and block cell cycle in G0-G1 phase.

OBJECTIVE: To investigate the mRNA and protein expression of MICA in laryngeal squamous cell carcinoma tissue and the Hep-2 cells. METHOD: Reverse transcriptase-polymerase chain reaction (RT-PCR) and Western-blot were used to detect the expression of MICA mRNA and protein levels in the Hep-2 cells and laryngeal cancer tissues. RESULT: The MICA mRNA showed higher expression in Hep-2 cells by RT-PCR. Compared with the control, the mRNA expression of MICA was significantly enhanced in laryngeal cancer tissues (t = 11.878, P < 0.01). The intensity of MICA expression is not related to the clinical stage of cancer. MICA protein demonstrated higher level expression by Western blot. The intensity of MICA protein expression was decreased with increased clinical stage in laryngeal cancer tissues. CONCLUSION The MICA mRNA showed stronger expression in Hep-2 cells and laryngeal cancer tissues. The intensity of its expression is not related to clinical stage of cancer. The MICA protein expression was strong in Hep-2 cells. The intensity of MICA protein expression was decreased with increased clinical stage in laryngeal cancer tissues. MICA may play an important role in laryngeal carcinoma process.

Objective To observe clinical therapeutic effect of treating insomnia by moxibustioning Balhui (DU20)and Sisbencong(EX-HN 1) . Methods 276 cases of insomnia were divided into treatment group and control group. The treatment group was treated by moxibustioning on Baihui (DU 20) and Sishencong(EX-HN 1); while the control group was treated by moxibutioning on Zusanli (ST 36). Evaluate the therapeutic effects and PSQI index of the two groups. Results Clinical symptoms got improvement in the both groups. The treatment group was better than the control group in terms of therapeutic effect of the (P＜0.05) and the improvement of PSQI (P＜0.01).

Objective: To explore the role of human hematopoietic growth factors (HGFs) in proliferation and differentiation of cord blood CD34+ cells. Methods: Human cord blood mononuclear cells (MNC) were cultured with different combinations of HGFs (including rhIL-1,rhIL-3, rhIL-6, rhG-CSF, rhGM-CSF and rhSCF). The expansion folds of MNC, the changes of cellular surface markers by FACS, and CFU-GM of hematopoietic cells were observed. Results: The total nucleated cells expanded by 44 folds after cultured with 6 cytokines for 20 days. The number of CFU-GM increased by 14 .74 folds after cultured in liquid for 8 days, but decreased heavily after 18 days. The total number of CD34+ cells increased by 127. 79 ~ 196 .40 folds at 6 to 8 day, but decreased to 101.51 folds at 18 day. Conclusion: Human hematopoietic growth factors can increase the expansion of cord blood CD34+ cells and CFU-GM significantly.
