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.

Objective To investigate the effects of Shenfu injection ( SF,a Chinese herbal medicine preparation made of Codonopsis pilosula and Aconitum carmichaeli) on the cell apoptosis of focal cerebral ischemic-reperfusion injured rats and the expression of heme oxygenase-1 (HO-1). Methods Forty-two male Sprague-Dawley rats used for producing unilateral brain ischemia reperfusion model were randomly divided into three groups:sham operation group ( Sham group),ischemia reperfusion group ( IR group),and SF Injection group (SF group).The model of focal cerebral ischemia-reperfusion injury was induced by transient occlusion of middle cerebral artery (ischemia for 2 h,and reperfusion for 3,6 h respectively).In SF group,SF ( 10 mg/kg) was intraperitoneally injected duri(n)g reperfusion.Cell apoptosis rate in brain tissue was detected by the technique of Annexin-V-PI double staining and was counted in flow cytometer.Expression of HO-1 in brain was measured by RT-PCR,while the pathological and ultra structure changes of cerebral tissue were also observed.Results Cell apoptosis rate of brain tissue were significantly higher in IR group than that in Sham group (P ＜0.01 ),while SF group had less significant changes in cell apoptosis rate, HO-1 level of brain tissue than IR group (P ＜ O.01 ).The ultra structure change of brain tissue was less in SF group than that in IR group.Conclusions During early stage of brain IR injury,SF inhibits cellular apoptosis and in turn protects the brain from injury which is attributed to the increase in HO-1 expression induced by SF.

Background:Fibroscan is the noninvasive method widely used to evaluate quantitatively the liver fibrosis and monitor the long-term efficacy of anti-fibrosis therapy. Aims:To study the use of Fibroscan for evaluating the efficacy of combined therapy with FuFang BieJia RuanGan tablet and antiviral drugs in patients with hepatitis B virus( HBV)-related cirrhosis. Methods:A total of 90 patients with HBV-related cirrhosis from March 2013 to September 2014 at Shanghai Ren Ji Hospital were recruited,and divided into treatment group and control group. Patients in treatment group received FuFang BieJia RuanGan tablet,and patients in control group received conventional liver-protective drugs,all the patients took nucleoside antiviral drugs at the same time. The treatment courses in both groups were 6 months. Liver stiffness measurement( LSM)was detected by Fibroscan before and after treatment. Biochemical parameters,width of portal vein and clinical symptoms were recorded. Results:After treatment,LSM was significantly decreased in both groups( P <0.05). Liver function,width of portal vein and Child-Pugh score were improved in both groups(P <0. 05),and no significant differences were found between the two groups(P>0. 05). LSM was closely associated with Child-Pugh score both before and after treatment(r=0. 484,P<0. 01;r=0. 523,P<0. 01). Patients with Child-Pugh A had lower LSM than those with Child-Pugh B or Child-Pugh C(P<0. 01). Conclusions:FuFang BieJia RuanGan tablet combined with oral antiviral drugs can remarkably improve the liver function of cirrhotic patients and prevent progression of cirrhosis. Dynamic detection of LSM can be used for monitoring drug efficacy and disease progression in patients with cirrhosis.

Background Eicosapentaenoic acid(EPA)function as the critical lipid mediators involved in several biological events in human body and play important role in suppressing the genesis of vascular endothelial growth factor (VEGF),migration and proliferation of vascular endothelial cells.Many ocular diseases were proved to be associated with neovascularization.Objecfive The purpose of this study was to investigate the inhibitory effect of EPA on the proliferation of human umbilical vein endothelial cells (HUVEC) indueed by VEGF. Methods HUVEC strain was cultured and passaged,and difierent concentrations of EPA were added to the medium with and without VEGF.The cultured cells were identified by antiofactor Ⅷ polyclonal antibody.The suppressing role of different concentrations of EPA on the proliferation of VEGF-induced or-uninduced HUVEC was assessed by MTT method.The influence of difierent concentrations of EPA on the cellular cycle of VEGF-induced HUVEC was assayed using flow eytometry.The expression of Flk-1,a receptor of VEGF,in the HUVEC Was detected by immunohistochemistry. Results Cultured HUVEC showed the ftlsiform in shape and presented with the cobblestone-like arrangement with the positive response for Ⅷ factor-related antigen.Various concentrations of EPA showed obviously inhibitory effect on VEGF-induced or-unindueed HUVEC at a dose-dependent manner (F=23.072.P=0.000).The inhibitory ability of EPA on VEGF-induced HUVEC was stronger than VEGF-uninduced HUVEC(F=41.417,P=0.000).In 24,48 and 72 hours,the action of EPA on the proliferation of HUVEC was gradually enhanced with the prolong of time(F=1.495,P=0.236).Cell cycle analysis indicated that EPA arrested VEGF-induced HUVEC in G0/G1 phase.The ratio of HUVEC in G0/G1 phase in EPA group was(75.83±1.56)%,and that in control groups was(68.62±1.44)%,showing a significant difference between them(t=-5.88,P=0.00),and no apoptosis of HUVEC was found in both groups.Flk-1 was strongly expressed in the cellular nucleus and cytoplasm in control group.However,the positive expressing intensity of Flk-1 in the HUVEC weakened,and the positive cell number was evidently less in EPA group. Conclusion EPA can inhibit the proliferation of VEGF induced HUVEC through arresting the synthesis of DNA of HUVEC and downregulate the expression of Flk-1 in HUVEC.These results suggest that EPA might exert an antiangiogenic effect.

Background Researches showed that as the non-optical factors,cognitive has certain influence on the regulating system.So accurately experimental design is one of the key steps that evaluates the non-optical factors on regulating system.Objective The present study was to investigate the influence of presenting pattern of target and watching way on the level and amplitude of accommodative fluctuate and to analyze the effect of focus gaze of cognitive on regulating system and the relationship between focus gaze condition under near work and the development of myopia.Methods This study complied with Declaration of Helsinki,and the permission of Ethic Committee and written informed consent was obtained before entering in this trial.Thirty healthy volunteers were included with the mean age (24.80 ± 1.98) years old,equivalent refractive diopter (-1.92 ± 2.02) D and mean cylinder (-0.19±0.58) D.The presenting pattern of the targets was designed as focus gaze and relaxed gaze.The accommodative response and accommodative fluctuation in the complete corrected right eyes for the different targets at the 40 cm under the gazing state was recorded with Grand Seiko WAM 5500 automatic infrared refractor in the experiment.Results The mean accommodative response value was (1.86±0.26) D under the focus gaze and (1.27±0.39) D under the relax gaze,showing a statistically significant difference (t=-8.052,P=0.000).The mean fluctuate value was(0.17±0.06) D under the focus gaze,with a significant lowing in comparison with (0.28±0.17) D under the relax gaze (t =3.600,P =0.001).Conclusions These results demonstrate that the different presenting patterns of sighting target and watching ways of the subjects affect accommodation system.The accommodative response was relatively more accurate with a smaller microwavc moving under the focus gaze condition.

Objective To investigate the effects of naloxone (Na) on pneumocyte apoptosis and expression of heme oxygenase-1 (HO-1) during ischemia reperfusion injury of lung in rats. Method Forty-two male Sprague-Dawley rats were made models of ischemia reperfusion injury of unilateral lung, and were randomly( random number) divided into three groups: sham operation group (Sh group), ischemia reperfusion group (IR group) and naloxone group (Na group). The hilus of lung was clamped for 45 minutes and the clamp was taken off to build the I/R model. After 3-6 hours reperfusion, naloxone in dose of 1 mg/kg was injected intra-peritoneally in rats of Na group. The rate of cell apoptosis in lung tissue was detected with the way of Annexin-V-PI in flow cy-tometer. The wet to dry weight ratio (W/D) of lung tissue was measured. The expression of HO-1 in lung was measured by using RT-PCR and the ultra-structure change of lung tissue was observed under electron microscope. Results The rate of pneumocyte apoptosis and W/D ratio of lung tissue were significantly higher in IR group than in Sh group (P < 0.01), and the rate of pneumocyte apoptosis and W/D ratio of lung tissue were negatively correlated with the expression of HO-1 mRNA in lung tissue. Compared with IR group, the rate of cell apoptosis and W/D ratio were lower and the expression of HO-1 mRNA was higher in Na group (P < 0.01). The ultra- structure changes of lung tissue were lessened in Na group than in IR group. Conclusions During early period of lung IR injury, HO-1 induced by naloxone can inhibit the cellular apoptosis and protect the lung tissue.
