Objective Henoch-Sch?nlein purpura(HSP)is a common multisystemic vasculitis in children ,but the exact pathogenesis remains unknown. Pentraxin 3(PTX3),a new kind of inflammatory cytokines,has a strong inflammatory effect,and is involved in occurrence and develop-ment of a variety of autoimmune diseases. The objective of this study is to evaluate the expression of PTX3,interleukin-8(IL-8),tumor necrosis fac-tor-α(TNF-α)and high sensitivity C-reactive protein(hs-CRP)in children with HSP,and explore the clinical significance of PTX3 in HSP devel-opment. Methods Thirty-six children(HSP group)and 17 healthy children(control group)were enrolled in the study. Serum levels of PTX3,IL-8 and TNF-α were detected by enzyme-linked immunosorbent assay. Serum hs-CRP levels were measured by automatic biochemical analyzer. Re-sults The serum levels of PTX3,IL-8,TNF-α,and hs-CRP were up-regulated in HSP group compared with the control group(P<0.05). The levels of PTX3,IL-8,TNF-α,and hs-CRP in patients with joint symptoms,or/and gastrointestinal symptoms,or/and kidney injury were significant-ly higher than those patients without joint symptoms,or/and gastrointestinal symptoms,or/and kidney injury(P<0.05). The expression of PTX3 was positively correlated with the expression of IL-8 and TNF-α(r=0.514,0.833,all P<0.05),but there was no correlation between PTX3 and hs-CRP(r=0.292,P>0.05). The expression of PTX3,IL-8,TNF-α and hs-CRP in HSP patients had no gender difference(all P>0.05). Con-clusion The high expression of PTX3 is related to the degree of inflammation in children with HSP. The up-regulated expression of PTX3 may play an important role in pathogenesis of HSP in children.

Objective To investigate the influence of electroacupuncturing Neiguan points on mitochondrial Ca2+release and cardiomyocyte apoptosis of diabetic cardiomyopathy in rats. Methods 30 Wistar rats were randomly divided into a control group, a model group and a treatment group(10 in each group). In the treatment group, after eight weeks electroacupuncture Neiguan point treating diabetic cardiomyopathy in rats, the myocardium was quickly removed,mitochondrial was extracted,dual-beam UV spectrophotometer was adopted to detecting Ca2+transportation by testing Ca2+indicator A Ⅲ absorbance, and Cardiomyocyte apoptosis was evaluated by terminal-deoxynucleotidyl transferase mediated deoxy-UTP nick end labeling (TUNEL). Results Ca2+ indicator A Ⅲ absorbance detection(0.051±0.014) and cardiomyocyte apoptosis(0.49±0.36)were more depressed in the treatment group than in the model group[(0.077±0.025), (0.53±0.04)], there were significantly different(P<0.05) Conclusion Effect of Electroacupuncturing Neiguan points decreased myocardial apoptosis index in rats with diabetic cardiomyopathy, which may be related to the reduction of mitochondrial Ca2+influx.

Objective To observe the change of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene expression during 3T3-L1 adipocyte differentiation as well as other reference gene expressions.Methods The mRNA expressions of several common reference genes were detected by real time-PCR on day 0,1,3,5,and 7 of 3T3-L1 adipocyte differentiation.Western blot was used to confirm the protein expressions of three common reference genes.Results (1) GAPDH and transferrin receptor(TFRC) mRNA expressions were significantly increased during adipocyte differentiation.GAPDH mRNA level was increased by 5.7,7.6,22.0,and 24.5 folds on day 1,3,5,and 7 after induction of adipocyte differentiation,but no apparent changes of β-actin,α-tubulin,peptidylprolyl isomerase A (PIPA),and 18S mRNA expressions were detected.The expression changes of key transcript factors for adipocyte differentiation such as PPARγ2,C/EBPα,and C/EBPβ were under-estimated by real time-PCR if GAPDH was chosen as the reference gene.Western blotting results showed that the GAPDH protein level increased gradually during adipocyte differentiation,especially on day 5 and 7 after adipocyte differentiation.There were no obvious changes of β-actin and α-tubulin protein expressions.(2) Berberine significantly inhibited mRNA and protein expressions of GAPDH in the process of adipocyte differentiation.GAPDH mRNA levels were reduced by 68.1％ and 66.3％ on day 5 and 7 after induction of adipocyte differentiation,but with no significant change in other reference genes.Conclusion It is not suitable for GAPDH to be used as an endogenous reference gene during 3T3-L1 adipocyte differentiation.

Objective To observe the effect of berberine on glucose transport in 3T3-L1 adipocytes and to investigate its mechanism. Methods The glucose consumption of the cells was determined by the glucose oxidase method. The glucose transportation rate of the cells was assayed by the uptake of 2-deoxy-〔 3H〕-D-glucose. Protein kinase B (Akt) activity was detected by immunoprecipitation and Western blot. The gene expression of c-Cbl-associated protein (CAP) was detected by Northern blot. Results 0.1～200 ?mol/L berberine significantly increased glucose consumption in 3T3-L1 adipocytes with a dose-dependent effect, which was independent of insulin. The glucose transportation was significantly increased in adipocytes incubated with 0.1～10 ?mol/L berberine; the action began at 2 h and reached a peak value at 12 h. The results of immunoprecipitation and Western blot showed that berberine did not enhance Akt activity. The result of Northern blot indicated that berberine significantly decreased CAP mRNA expression. Conclusion Adipocytes are the important target cells of berberine. Berberine significantly increases glucose transportation and consumption in adipocytes, the action appeares to be independent of insulin signal pathway.

Objective To study the role of pancreatic renin-angiotensin system (RAS) on insulin secretion, proliferation, apoptosis, oxidative stress, and fibrosis of β-cells. Methods The effect of angiotensin Ⅱ on βTC3 cells was studied and the role and mechanism of AT1 R were analyzed with RNAi technology. The expression of AT1 R was measured by Western Blotting. The change of intracellular calcium was detected by microfluorimetry with Furo3-1oaded cells. Peroxide-sensitive fluorescent probe DCFH-DA was used to analyze intracellular ROS by flow cytometry. Real-time PCR was performed to evaluate mRNA levels related to proliferation and fibrosis in βTC3 cells. Apoptosis was detected by flow cytometry and Tunel method. Results Insulin secretion was significantly increased up to four fold and the level of intracellular calcium was sharply increased in response to high glucose in βTC3 cells. Angiotensin Ⅱ has no direct effect on insulin secretion in βTC3 cells and its role in secretion was associated with the role in proliferation. Oxidative stress in βTC3 cells caused by angiotensin Ⅱ may be partially mediated through AT1R, protein kinase C and NAD(P) H. With the decrease of AT1R expression by RNAi technology, apoptosis, and fibrosis of βTC3 cells induced by angiotensin Ⅱ might be ameliorated.Conclusions By means of AT1R, angiotensin Ⅱ plays an important role in insulin secretion, proliferation,apoptosis, oxidative stress and fibrosis in β-cells.

Isolated freshly rat islets were transferred to 24-well plates and incubated with different concentrations of glucose or resveratrol for 1 or 24 h.The results showed that resveratrol dose-dependently inhibited glucose-stimulated insulin secretion from isolated rat islets after 1 h incubation,with 10%,35%,and 80% (P<0.05 or P<0.01) decrease at the concentrations of 1,I0,and 100 μmol/L.10 μmol/L resveratrol decreased the intracellular calcium concentration by 60% (P<0.05).After incubation for 24 h,resveratrol increased palmitatesuppressed insulin secretion to 75% (P<0.01) of control.These results suggest that resveratrol acutely inhibits insulin secretion from primary pancreatic islet via regulating intracellular calcium ion concentration,and in the long run resveratrol may protect β-cells from lipotoxicity.
