Objective To explore the effect of isometric contraction-induced ischemic burden for evoking maximal intrinsic femoral artery collateral circulation. Methods Twenty-four adult New Zealand rabbits weighing (2.0±0.5) kg were subjected to a model of isometric contraction-induced ischemia. An electrode was implanted in the sciatic nerve of the left hind limb for evoking isometric contraction of the gastrocnemius, which blocked local blood flow and induced local ischemia. Femoral artery collateral blood flow (FCBF) was measured using a micro-sphere technique. Results Local blood flow was the lowest at 40% of the maximal isometric contraction (IEmax), and reached plateau at 60% of IEmax. FCBF increased gradually and reached a plateau at 40% of IEmax in the 4th min. After 4 minutes at 40% of IEmax, FCBF had increased to higher than pre-stimulus, peaking in the 2nd minute, and then decreasing gradually to baseline at the 5th minute after reperfusion. It ceased to increase when reperfusion was prolonged to 8 or 10 min. Conclusions The minimal ischemic burden for full obstruction of the femoral artery is 40% of IEmax, and the shortest stimulus duration is 4 min. The maximal FCBF opening duration is no more than 5 min.

Objective: To study the origin, morphological structure, and functional regulation of osteoclast(OC) for further investigation on the mechanism and regulation of bone resorption. Methods: The OCs were isolated by two kinds of traditional method. Osteoclasts were isoclated from neonatal rat long bones. The cytochemistry was observed. The osteoclast-like cells (OLC) were derived from the mouse bone marrow cells in the presence of 1,25(OH)2VitD3 in vitro. Results: Both morphological and functional studies showed that the isolated cells shared some of the typical characteristics of osteoclasts, that is A. multinuclearity; B. developing spreading and pseudopodial activity when cultured on glass; C. high tartrate-resistant acid phosphatase (TRAP); D. resorption lacunae could be found when the cells were cocultured with devitalized bone slices and the number was increased as the time followed. OLC had the same histological and structural traits as the OCs by the former method. The concentration of Ca 2+ and acid phosphatase (ACP) increased gradually. Conclusion: Different kinds of method fit different experiments. The OC obtained by the first method has more activity of bone resorption. The OLC by the second method has more in quantity and can be used in the study of cell differentiation.

Objective Abnormal activation of mitogen-and stress-activated kinase (MSK1) plays an important role in the development of various cancers.This study was to explore the effect of small interfering RNA (siRNA)-mediated MSK1-silencing on the proliferation of human nasopharyngeal carcinoma (NPC) cells and its underlying mechanism.Methods The siRNA vector targeting MSK1 was constructed and transfected into CNE2 cells, and the NPC cell line stably expressing MSK1 was established.Then the cells were divided into a blank control (without transfection of the plasmid), a negative control (with stable transfection of the negative control plasmid), and an experimental group (with stable transfection of the positive recombinant plasmid).The expressions of MSK1 mRNA and protein were detected by real-time quantitative PCR and Western blot, respectively, the proliferation of the cells determined by CCK-8 and colony formation assays, the cell cycles analyzed by flow cytometry, the level of histone H3 phosphorylation at Ser10 examined by Western blot, and The transcriptional activity and expression of the c-jun protein measured by dual-luciferase reporter gene assay and Western blot.Results Compared with the blank control, the inhibition rates of cell proliferation at 48, 72 and 96 hours were significantly reduced in the experimental group (P<0.05), and so were the colony formation ability of the cells (P<0.01) and the expression and transcriptional activity of the c-jun protein (P<0.05).In comparison with the negative control, the experimental group showed significant decreases in the rate of cell growth after 24 hours, the inhibition rates of cell proliferation at 48, 72 and 96 hours (P<0.05), the number of formed colonies ([221.00±20.08] vs [99.67±15.57] / 300 cells, P<0.01), the proportion of S-phase cells (P<0.01), and the expression of the c-jun protein in the CNE2 cells ([100.00±0.00] vs [48.77±10.71] %, P<0.05), but a remarkable increase in the percentage of G0/G1-phase cells (P<0.01).Furthermore, histone H3 phosphorylation at Ser10 was markedly reduced (P<0.01) but no significant change was observed in the expression of the total c-jun protein in the experimental group.Conclusion Knockdown of MSK1 using siRNA can significantly inhibit the growth and proliferation of CNE2 cells, which may be closely related to the decreased phosphorylation of histone H3 and subsequently down-regulated transcriptional activity of c-jun.

Objective To investigate the specific immune therapeutic effect of the T cell fusion peptide vaccine from group II allergens from Dermatophagoides pteronyssinus(Der p2). Methods Thirty mice were randomly divided into three groups, namely a negative control group(a PBS group),positive control group(an asthma group)and protein Der p2 T cell fusion epit?ope for specific immunotherapy(SIT)group(a Der p2 T group). The extract of house dust mites(HDM)was used to establish the asthmatic models in BALB/c mice,and the PBS group was always used with PBS buffer. Thirty minutes before spray inhala?tion from 25 to 27 days,the mice of the Der p2 T group were respectively injected subcutaneously with the therapeutic proteins for SIT,then the serum and bronchoalveolar lavage fluid(BALF)were collected. ELISA was used to assay the levels of IFN?γ, IL?4,and IL?13 in BALF,as well as serum levels of specific IgE and IgG2a. The lung tissue sections were stained with haematox?ylin and eosin(H&E)for pathological examinations. Results The ELISA detection revealed that the number of eosinophil in BALF of the asthmatic mice was(5.57 ± 0.64)× 105/ml,which was significantly higher than that in the PBS group[(0.50 ± 0.30)× 105/ml,P < 0.01],the number of eosinophil in the Der p2 T immunotherapy group decreased significantly[(3.45 ± 0.36)×105/ml,P<0.01]. The content of IFN?γin the PBS group,asthma group and Der p2 T group were(267.00 ± 21.98), (155.80 ± 20.53)pg/ml and(234.40 ± 24.46)pg/ml respectively. Compared with the asthma group,the mice with Der p2 T vac?cine specific immune treatment produced a high level of IFN?γ(P<0.01). The content of IL?4 in the PBS group,asthma group and Der p2 T group were(23.40 ± 5.96),(53.28 ± 8.26)pg/ml and(30.00 ± 5.50)pg/ml respectively. Compared with the asth?ma group,the content of IL?4 in the mice of the Der p2 T treatment group was significantly lower(P<0.01). Compared with the asthma group[(308.10 ± 28.32)pg/ml],the content of IL?13 in BALF of the mice in the Der p2 T treatment group was signifi?cantly decreased,which was[(174.50 ± 25.99)pg/ml,P<0.01]. The content of IL?13 in the PBS group was(95.99 ± 31.14) pg/ml. The lung tissue sections showed that the lung inflammation in the p2 T Der group was significantly less than that in the asthma group,and the inflammatory cell infiltration was significantly decreased,and airway epithelial construction remodeled. Conclusion The Der p2 T cell fusion epitope,which is as vaccines for specific immunotherapy with asthma models,can allevi?ate effectively allergic inflammation of airway and lung in the mice,and it may be used as a candidate vaccine for asthma.
