RESULTS & CONCLUSIONS: Among those suitable strategies, which include scale enlargement, service differentiation, and countryside & community market expansion etc, small and medium enterprises should choose different kinds of strategies according to their special characteristics. Meanwhile they should incessantly enhance their real strength and spare no effort to cultivate their own competitive advantage to seek survival and development.

Changes of pulmonary ?_1-and ?-adrenergic receptor (?_1-AR and ?-AR)during endotoxin-induced acute lung injury in rates were oberved to find out the rela-tionship between them and the mechanism of change. Results showed that there was amarked decrease of B_max of both ?_1-AR and ?-AR by 35% and 43% respectively, dur-ing acute lung injury. The down regulation of ?-AR might be one of causes of acutelung injury while that of ?_1-AR seems to be a protective response. Active oxygen playedan important role in endotoxin-induced down regulation of AR in the rat lungs. The increa-sed level of norepinephrine and epinephrine was not the main factor that initiate the downregulation of AR. Intravenous injection of tumor necrosis factor (5?10~6U/kg ) exerts noiafluence on the changes of pulmonary AR in rats.

Objective To evaluate the relationship between protein kinase B (AKT) and protein kinase (PKCθ) and morphine-induced inhibition of differentiation of T helper (Th) cells.Methods Peripheral venous blood samples were taken from 20 healthy volunteers..Peripheral blood mononuclear cells (PBMCs) were extracted by density gradient centrifugation method.CD4+ T lymphocytes extracted were purified by magnetic bead separation.CD4+ T lymphocytes were randomly assigned into 5 groups (n =3 each) using a random number table.CD4 + T lymphocytes were incubated routinely in group C.CD4 + T lymphocytes were incubated in the presence of PMA 25 ng/ml + ionomycin 1 μg/ml (group PI),PMA 25 ng/ml + ionomycin 1 μμg/ml + morphine 50 μμg/ml (group M),or PMA 25 ng/ml + ionomycin 1 μμg/ml + morphine 50 μg/ml + naloxone 50 μμg/ml (group N).The cells were incubated for 4 h in the incubator containing 5％ CO2 at 37 ℃.The expression of interferon (IFN)-γ and interleukin-4 (IL-4) was detected by flow cytometry.The expression of IFN-γ and IL-4 was used to reflect the percentage of Th1 and Th2 cells,respectively.The ratio of Th1/Th2 was calculated.The expression of AKT,phosphorylated AKT (p-AKT),PKCθ and phosphorylated PKCθ (p-PKCθ) was detected by Western blot,and the ratio of p-AKT/AKT and p-PKCθ/PKCθ was calculated to reflect the activities of AKT and PKCθ,respectively.Results Compared with group C,the percentage of Th1 and Th2 cells and ratio of Th1/Th2 were significantly increased in PI,M and N groups,the activities of AKT and PKCθ were increased in PI and N groups,and the activity of PKCθ was increased in group M (P ＜ 0.05).Compared with group PI,the percentage of Th1 cells,ratio of Th1/Th2 and activity of AKT were significantly decreased in group M,the ratio of Th1/Th2 was decreased in group N (P ＜0.05),and no significant change in the activity of PKCθ was found in M and N groups (P ＞ 0.05).Compared with group M,the percentage of Th1 cells,ratio of Th1/Th2 and activity of AKT were significantly increased (P ＜ 0.05),while no significant change in the activity of PKCθ was observed in group N (P ＞ 0.05).Conclusion The mechanism by which morphine inhibits the differentiation of Th cells through activating opioid receptors is related to inhibition of AKT activation,but not related to PKCθ.

Objective To evaluate the relationship between GATA-3 and T-bet and inhibition of the differentiation of human T helper cells by morphine.Methods Ten healthy volunteers,aged 20-50 yr,weighing 50-70 kg,were enrolled in the study.Peripheral venous blood samples were taken in the early morning.Peripheral blood mononuclear cells (PBMCs) were isolated and assigned into 5 groups (n=10 each).PBMCs were incubated routinely (group C).PBMCs were incubated in the presence of PMA and ionomycin (group P),morphine 50 μg/ml (group M),morphine 50 μg/ml + naloxone 50 μg/ml (group MN) or naloxone 50μg/ml (group N),and were then stimulated with PMA and ionomycin for another 4 h.The percentage of Th1 and Th2 cells was detected by flow cytometry.The Th1/Th2 ratio was calculated.Interferon (IFN)-γ and interleukin (IL)-4 concentrations in the supematant were determined using ELISA.The activities of GATA-3 and T-bet were analyzed by EMSA.Results Compared with group P,the percentage of Th1 and Th2 cells,Th1/Th2 ratio,IFN-γand IL-4 concentrations in the supernatant,and GATA-3 and T-bet activities were significantly decreased in group M,the percentage of Th1 cells,Th1/Th2 ratio,and IFN-γ concentration in the supernatant were significantly decreased in group MN (P ＜ 0.05 or 0.01).Compared with group M,the percentage of Th1 and Th2 cells,Th1/Th2 ratio,IFN-γ and IL-4 concentrations in the supernatant,and GATA-3 and T-bet activities were significantly increased in group MN (P ＜ 0.05 or 0.01).There was no significant difference in the indexes mentioned above between groups N and C (P ＞ 0.05).Conclusion Morphine inhibits the differentiation of human T helper cells by activating opioid receptors,which may be related to the inhibition of GATA-3 and T-bet activities.

Objective To explore the level of the oxidative stress and the DNA oxidative damage of peripheral blood mononuclear cells (PBMCs) in pulmonary embolism (PE) patients after remission and in acute exacerbation.Methods The PBMCs DNA damage in 35 PE patients (test group) after remission and in acute exacerbation respectively and in 33 healthy persons (control group) was detected by single-cell gel electrophoresissingle (Comet assay).The total antioxidative capacity (TAC) in blood plasma was measured by phenanthroline colorimetric analysis.The contents of malondialdehyde (MDA) in blood plasma was measured by thiobarbituricacid colorimetric analysis.The capacity of glutathion peroxidase (GSH-PX) in blood plasma was measured by the method of improved Hafeman direct determination method (DNTB).Results The level of TAC,GSH-PX in test group after remission were significantly higher than those in acute exacerbation[(6.86 ± 1.21) kU/L vs.(5.18 ± 1.13) kU/L,(165.25 ± 41.96) kU/L vs.(137.23 ± 38.52) kU/L] (P ＜0.01),and they were all significantly lower than those in control group [(7.85 ± 1.44),(189.92 ± 51.32) kU/L] (P ＜ 0.01).The level of MDA in test group after remission was significantly lower than that in acute exacerbation [(5.58 ± 1.89) μmol/L vs.(7.26 ± 2.25) μmol/L] (P ＜ 0.01),and they were significantly higher than that in control group [(3.71 ± 1.52) μmol/L] (P ＜ 0.01).The arbitrary units (AU) of PBMCs DNA damage in PE patients after remission (29.01 ± 6.75) was significantly lower than that in acute exacerbation (42.13 ± 8.01),and they were all significantly higher than that in control group (15.12 ± 4.36),there were significant differences (P＜ 0.01).There were negative correlations between the PBMCs DNA damage and the level of TAC in PE patients after remission and in acute exacerbation (r =-0.695,P ＜ 0.01 ;r =-0.536,P ＜ 0.01).There were positive correlations between the PBMCs DNA damage and the contents of MDA in PE patients after remission and in acute exacerbation (r =0.513,P ＜ 0.01 ;r =0.628,P ＜ 0.01).There were negative correlations between the level of TAC and the contents of MDA in PE after remission and in acute exacerbation respectively (r =-0.534,P ＜ 0.01 ;r =-0.486,P ＜ 0.05).There were positive correlation between the level of TAC and GSH-PX in PE patients after remission and in acute exacerbation (r =0.512,P ＜ 0.01 ;r =0.497,P ＜ 0.01).Conclusions There are oxidation/antioxidation imbalance,oxidative stress and the PBMCs DNA damage in PE patients.There is positive correlation between the PBMCs DNA damage and the oxidative stress.After remission,the level of the oxidative stress and the PBMCs DNA oxidative damage in the same PE patients is improved respectively.

Objective To observe the latency and amplitude characteristics of event-related potential P300 under different target stimu-lus. Methods During January to December, 2014, 35 patients with memory impairment received P300 test under the percentage of target stimuli of 0.10 and 0.25. The latency, amplitude and area under amplitude were compared. Results There was no significant difference in la-tency (t<0.256, P>0.800), but the amplitude and area under amplitude increased under 0.10 compared with those under 0.25 (t>4.259, P<0.05). Conclusion Less target stimulation may improve the patients' attention and increase amplitude of P300, but no more interference in la-tency, suggesting latency of P300 is more stable for assessment of cognitive function.

0.05). VIP, however, could inhibit the Con A-induced proliferation of T-cells from control subjects more significantly than that from asthmatics (P0.05). The cAMP level in T-cells, however, increased more significantly in the control group than that in the asthmatic group after the treatment of VIP or NaF (P0.05). CONCLUSION: Inhibition effect of VIP on Con A-induced proliferation of T-cells was less in asthmatics than in control subjects, which may be related to insufficiency of Gs ? coupled VIP receptor on T-lymphocytes in asthmatics.
