OBJECTIVE:To observe therapeutic efficacy and side effect of perospirone in the treatment of elderly depression. METHODS:64 elderly patients with depression were randomly divided into paroxetine combined with perospirone group (drug combination group) and paroxetine group (single drug group) with 32 patients in each group. Both groups were given paroxetine 20-40 mg/d,and drug combination group was additionally given perospirone 4-8 mg/d. HAMD and CGI-SI were adopted to evalu-ate therapeutic efficacy after 8 weeks treatment,and side effect was evaluated with TESS scale;those were compared between 2 groups. RESULTS:After 8 weeks treatment,the effective rate of drug combination group and single drug group were 75.0% and 50.0%;there was statistical significance(P<0.05). There was statistically significant difference in HAMD and CGI-SI scores be-tween two groups(P<0.05). There was no statistically significant difference in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Small-dose of perospirone can improve therapeutic efficacy of paroxetine in the treatment of elderly depression with less side effect and good safety.

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.

OBJECTIVETo explore the mechanisms involved in the ligustrazine alleviation of the pulmonary artery hypertension (PAH) in patients of chronic obstructive pulmonary disease (COPD) associated with chronic cor pulmonale (CCP) during exacerbation.

METHODSSeventy patients of COPD and CCP with acute exacerbation were randomly and equally divided into control group and treatment group. The control group received standard treatment with antibiotics, antiasthmatic and expectorant medications, and oxygenation; and the ligustrazine treatment group received ligustrazine treatment (80 mg/d; i.v.; for 2 weeks) in addition to the standard treatment. Before and at the end of 2 week treatment, the clinic responses of the two regimens were evaluated, plasma levels of endothelin-1 (ET-1) and nitric oxide (NO) were determined; arterial oxygen partial pressure (PaO2, mean pulmonary arterial pressure (mPAP), outflow tract of right ventricle (RVOT), and internal diameter of right ventricle (RV) were measured.

RESULTSGood clinic benefits were achieved in both the standard and ligustrazine regimens, plasma level of ET-1, values of mPAP, RV and RVOT decreased significantly, plasma level of NO and PaO2 values decreased (all P < 0.01 vs pre-treatment to all parameters). Compared with the control group, ligustrazine greatly enhanced the clinic efficacy from 77.1% to 97.1% (P < 0.05), and also resulted in more significant changes of all these parameters (P < 0.01 vs control group for all parameters). For both groups, the levels of plasma ET-1 were positively correlated with values of mPAP, RVOT, and RV (r = 0.710, 0.853, and 0.766, respectively, all P = 0.000), and negatively correlated with plasma NO and PaO2 (r = - 0.823, and - 0.752, respectively, all P = 0.000).

CONCLUSIONLigustrazine is effective in treating pulmonary artery hypertension during acute exacerbation of COPD and CCP in patients from the plateau area. The observed changes in the plasma levels of NO and ET-1 in response to ligustrazine treatment suggest that ligustrazine may act through the selective effect on pulmonary blood vessels to enhance the synthesis and release of NO and suppress those of ET-1 from lung vascular endothelial cells, thus reducing pulmonary artery pressure and decreasing pulmonary arterial hypertension.

Objective To study the macrophage colony-stimulating factor(M-CSF)expression levels of serum and synovial fluids from patients with spondyloarthropathy(SPA)and its contribution to the pathogen- esis of SpA.Methods Eleven SpA synovial tissue samples were compared to those from peripheral blood mononuclear cells(PBMC)of 10 normal subjects using a 1176 gene array.M-CSF was detected in both serum samples and synovial fluids by enzyme linked immunosorbent assay(ELISA).Two groups of AS subjects were tested.The first group consisted of 41 ankylosing spondylitis(AS)patients who had not been treated with bio- logics.The second group consisted of 13 subjects whose serum samples were collected before and 14 weeks af- ter initiation of infliximab.These were compared to serum samples from 28 normal subjects,and synovial fluid samples from 15 SpA patients.Results Expression of M-CSF could be detected in both serum samples and synovial fluids.The concentration of M-CSF in the group of 41 AS patients not treated with biologics correlated with the Bath Ankylosing Spondylitis Disease Activity Index(BASDAI)values(r=0.41,P=0.004).Treatment of infliximab in AS patients led to a significant decrease in the values of BASDAI(P=0.000 07),but no signif- icant change in the serum M-CSF values.Conclusion M-CSF is a promising candidate for research on the mechanisms of SpA and its signaling on pathway in SpA is different from tumor necrosis factor(TNF)-?,and it may provide new basis for developing new anti-biologics for SpA.

Amyloid β-peptide (Aβ) stimulating inducible nitric oxide synthase (iNOS) induces neuron death or apoptosis through the transcription factor NFκB (nuclear factor κB) signal pathway mechanism. Aβ functiones together with microglia and astrocyte to stimulate the inflammatory responsecorrelative with expression ofiNOS, the activation of the NFκB signal pathway and the expression ofiNOS,which results in significant peroxynitrite damage to neurons and the neurodegeneration in Alzheimer's disease (AD). Activation of CD36 signaling in microgila by Aβ fibrils initiates the association of the Src-family kinase Lyn with CD36. Together with another Src kinase, Fyn, Lyn activates a MAPK signaling response and results in the activation of inflammatory programs such as the production of MCP-1 and ROS.In parallel, Syk-family kinase activity specifically regulates increased cytokine production in response to Aβstimulation. After the stimulation, NFκB works independent of Src and Syk activation. Aβ-stimulated microglial secretes TNF-α and O2-, resulting in iNOS overexpression and excessive peroxynitrite and neuronal apoptosis.
