0.05).The positive expression rate of CXCR4 was 96% in cancer cells in regional metastasized lymph nodes.And its expression was lower than that in primary tumors(P

Objective: To study the effect of Resen heche tablets (RSHC) on tonyfing and warming Shen Yang. Methods: The mice model of Shen Yang deficiency was established by injecting hydrocortisone. The body weight, autonomic activity and swimming time in ice water in model mice were observed. The level of superoxide dismutase (SOD) in red cell and lipid peroxide (LPO) in plasma of aged rats were analyzed. The effect on anti stress in mice was examined. Results: RSHC had the remarkable effect to improve body weight and autonomic activity and to prolong swimming time in ice water in model mice, and to increase SOD activity and reduce LPO in blood of aged rats, and to elevate the ability of anti fatigue and anoxic tolerance in mice. Conclusion: RSHC drug has the effect on tonifying and warming Shen Yang; can promote growth, enhance organism activity, elevate the adaptation to circumstances and protect injury from free radicals.

The pathological changes in myocardial cell of diabetic rats were consistent with diabetic cardiomyopathy. The levels of adiponectin and the expression of T-cadherin in diabetic group were increased gradually,and higher than in normal control group

Objective To investigate the expression of activator protein-1 (AP-1) in PBMCs from patients with dermatomyositis (DM) and glucocorticoid effect on the expression.Methods PBMCs were isolated from 15 normal human controls and 20 patients (including 12 patients with primary DM who had never received glucocorticoid treatment and 8 patients with recurrent DM who had stopped glucocorticoid treatment for more than 1 month),and classified into two parts:one was cultured in RPMI 1640 medium with dexamethasone of 80 μmol/L and 10％ calf serum for 48 hours,and the other was frozen at -80 ℃ and reserved.Electrophoretic mobility shift assay (EMSA) was carried out to detect the activity of AP-1 in these cells.Results The expression (grayscale area) of AP-1 in the PBMCs from the normal controls was 4.93 ± 0.15 mm2.A significant decrease was induced by the treatment with dexamethasone in the expression (grayscale area) of AP-1 from PBMCs of patients with primary DM and those with recurrent DM (5.59 ± 0.39 vs.30.23 ± 0.49 mm2,5.69 ± 0.39 vs.34.79 ± 0.61 mm2,F =13812.64,P ＜ 0.01 ).The activity of AP-1 was statistically higher in the PBMCs from patients with recurrent DM than in those from patients with primary DM before the treatment with dexamethasone (P ＜ 0.01 ).Conclusions The enhanced activity of AP-1 may be an important factor inducing the inflammatory reaction in and recurrence of DM.Glucocorticoids may suppress the AP-1 activity to a certain degree.

Objective To investigate the association of expressions of neutrophil extracellular trap (NET) and B lymphocyte in renal tissue with lupus activity in patients with lupus nephritis (LN). Methods Immunohistochemistry was.used to detect the expression of NET (citrullinated histone H3 as the marker) and the infiltration of B lymphocyte (CD19 as the marker)in renal specimens of three groups [LN group,n=20; minimal change disease (MCD) group,n=8;healthy control group,n=3].The chronic index and SLE-disease activity index (SLE-DAI) in renal tissues of LN and their correlations with NET and B lymphocytes were examined. Results The expression of NET was not found in the renal tissues of healthy control group and MCD group,while it increased significantly in LN group,especially in glomeruli with moderate and severe mesangial cells proliferation, cellular crescents, and tubulointerstitium with inflammatory cell infiltration.Compared with other types of glomeruli,the expression of NET was significantly upregulated in glomeruli with moderate and severe mesangial cell proliferation (P＜0.01).In the glomeruli with moderate and severe glomerular mesangial cell proliferation,the mean number of =NET positive cells was positively correlated with renal pathological active index (r=0.620,P=0.004),the score of SLE-DAI (r=0.492,P=0.027) and the mean number of NET positive tubular cells (r=0.558,P=0.011).In renal interstitium,the NET positive cells were positively correlated with CD19 positive B lymphocytes (r=0.573,P=0.008) and renal pathological chronic index (r=0.645,P=0.002). Conclusion NET is widely expressed in the renal tissues of lupus nephritis,which may play a role in the active damage of glomeruli.

Oligodeoxynucleotide containing unmethylated cytosine phosphate-guanosine motif(CpG ODN) may induce high expression of CD80, CD86, CD83, HLA I and HLAⅡ molecules on dendritic cells(DC) and stimulate DC to produce high level of IL-6, IL-12, TNF-? and IFN-?. CpG ODN is demonstrated in vivo to be a very potent adjuvant for Th1 cells, regulating Th0 cells to develop toward Th1 cells. Its role for DC is characteristics of CpG ODN sequence specificity and species specificity. CpG ODN is, at present, considered as a pathogen associated molecular pattern which binds its specific receptor,Toll-like receptor 9,then functions through TLR/IL-1R signaling pathway. It may represent a new therapeutic drug for broad applications in infectious disease, autoimmune disease, allergy and cancer therapy.

Objective To discuss the rule of distribution of TCM syndromes of Psoriasis (Ps).Methods The 205 Ps vulgaris outpatients were investigated and the case research forms were filled in.Based on the diagnosis standard of TCM syndromes,the patients were differentiated into different syndromes.The correlation between the syndromes and clinical materials were discussed.Results The main TCM syndromes of Ps were blood heat,blood stasis,blood dryness,blood heat-stasis,blood heat-dryness and blood stasis-dryness.The distribution of these six main syndromes in different ages,disease stages,and recurrent time in different groups was significantly different (P

Objective To examine the expression of protein kinase C (PKC), connexin43(Cx43) and non-phosphorylated Cx43 in ovarian cancer, and discuss the role of phosphorylated of Cx43 in chemoresistance in ovarian cancer. Methods We examined the expression of Cx43, non-phosphorylated Cx43 and PKC in ovarian cancer tissue by immunohistochemistry, and compared their expression in chemosensitivity group and ehemoresistance group. Cisplatin resistant ovarian cancer cell line SKOV3/DDP cells were treated by staurosporine (a kind of PKC inhibitors). Then expression of Cx43, non-phosphorylated Cx43 and PKC were tested. Meanwhile, we tested chemosensitivity of SKOV3/DDP cells by ATP bioluminescence tumor chemosensifivity assay (ATP-TCA). Results (1) Immunohistochemically,the rates of positive expression of Cx43 and non-phospharylated Cx43 were 54%, 14% respectively in the chemoresistance group, which were 83%, 59% in the chemosensitivity group respectively (P<0.05). The rate of positive expression of PKC in 28 chemoresistance ovarian cancer cases (64%) was higher than that in 29 chemosensitivity cases (31% ,P<0.05). Both of them were significantly lower in ehemoresistanee group than in chemosensitivity group (P<0.05). In addition, the expression of PKC was negatively correlated with the expression of Cx43 and non-phosphorylated Cx43. The correlation coefficients were -0. 626 and -0. 714, respectively (P<0.05). (2) Immunohistochemically, PKC was down regulated, and Cx43 and non-phosphorylated Cx43 were up regulated in SKOV3/DDP cells after staurosporine treatment. The longer the staurosporine worked, the more expression of Cx43 was. (3) By ATP-TCA, SKOV3/DDP cells were resistant to paclitaxel and cisplatin. The tumor growth inhibition was higher in the group of paclitaxel or cisplatin combined staurosporine than in the group of paclitaxel or cisplatin alone. The sensitivity was intermediate in the group combined with low concentration staurosporine (1×10-8 moL/L), and the sensitivity was high in the group combined with high concentration staurosporine (1×10-7 mol/L). Conclusions Phosphorylation of Cx43 caused by PKC leads to decrease in the expression of Cx43. This effect makes ovarian cancer cells less chemosensitive. Phosphorylation of Cx43 caused by PKC can be inhibited by staurosporine.
