Our previous studies showed that the anti-inflammatory effects of Paeonia lactiflora roots extract may be mediated, at least in part, through its gallic acid content, and this effect may be regulated in part by an inhibition on c AMP-phosphodiesterase（PDE）. To explore the anti-inflammatory effect and mechanism, the influence of gallic acid on neutrophils PDE4 activity and expression, TNF-α and IL-6 content and rat arthritis model were further studied. PDE4 activity and gene express were calculated respectively by substrate c AMP change examined with HPLC and real-time RT-PCR. The concentration of IL-6 and TNF-α in supernatant were assayed by ELISA method. Model of rat arthritis was caused by complete Freund＇s adjuvant. Results showed that gallic acid had a dose-dependent restraint on PDE4 activity of neutrophils in vitro, promoted significantly PDE4 A expression（P〈0.01）, and had no influence on the expressions of PDE4 B and 4D. However, PDE4 C expression was not detected. Gallic acid could promote IL-6 release（P〈0.05）, and inhibit TNF-α release of neutrophils（P〈0.05）. The experiment in vivo showed that gallic acid had obvious restraint on local inflammation of animal model（P〈0.05）. Therefore, the anti-inflammatory effect of gallic acid may be mediated in part through an inhibition on PDE4 activity and further an increase of IL-6 and a decrease of TNF-α of neutrophils, and this effect seemed to have no relationship with PDE4 expression.

BACKGROUND Obesity worsens inflammatory organ injury in acute pancreatitis(AP), but there is no effective preventive strategy. Sheng-jiang powder(SJP) has been shown to alleviate multiple-organ inflammatory injury in rats with high-fat diet-induced obesity. Hence, SJP is supposed to have an effect on multiple-organ inflammatory injury in AP in rats fed a high-fat *** To explore how obesity may contribute to aggravating inflammatory organ injury in AP in rats and observe the effect of SJP on multiple-organ inflammatory injury in AP in rats fed a high-fat *** Rats were randomly assigned to a control group(CG), an obese group(OG), and an SJP treatment group(SG), with eight rats per group. The rats in the OG and SG were fed a high-fat diet. From the third week, the rats in the SG were given oral doses of SJP(5 g/kg of body weight). After 12 wk, AP was induced in the three groups. Serum amylase level, body weight, Lee's index, serum biochemistry parameters, and serum inflammatory cytokine and tissue cytokine levels were assessed, and the tissue histopathological scores were evaluated and *** Compared with the CG, serum triglyceride, total cholesterol, interleukin-6, and interleukin-10 levels were significantly higher in the OG, and serum high-density lipoprotein cholesterol level was significantly lower in the OG. Moreover,enhanced oxidative damage was observed in the pancreas, heart, spleen, lung,intestine, liver, and kidney. Evidence of an imbalanced antioxidant defense system, especially in the pancreas, spleen, and intestine, was observed in the obese AP rats. Compared with the OG, serum high-density lipoprotein cholesterol, interleukin-10, and superoxide dismutase expression levels in the pancreas, spleen, and intestine were increased in the SG. Additionally, SJP intervention led to a decrease in the following parameters: body weight; Lee's index; serum triglyceride levels; serum total cholesterol levels; malondialdehyde expression levels

AIM To investigate the mechanisms by which Sheng-jiang powder(SJP) ameliorates obesity-induced pancreatic inflammatory *** Sprague-Dawley rats were randomized into three groups: normal group(NG), obese group(HLG), or SJP treatment group(HSG). Obesity was induced by feeding a high-fat diet in the HLG and HSG, while the NG received standard chow. Rats were euthanized after 12 wk, and blood and pancreatic tissues were collected for histopathological analyses. Nuclear factor kappa-light-chain-enhancer of activated B cells(NF-κB) and transforming growth factor beta(TGF-β) expression, serum triglyceride and adiponectin levels, and apoptosis in pancreatic acinar cells were assessed. A high-fat AR42 J acinar cell injury model was established using very low-density lipoprotein(VLDL). AR42 J acinar cell culture supernatant, treated with different interventions, was applied to seven groups of pancreatic stellate cells(PSCs). The proliferation of PSCs and the expression of fibronectin and type I collagenase were *** Compared with the NG, we found higher pathological scores for pancreatic tissues, lower serum adiponectin levels, higher expression levels of NF-κB in pancreatic tissues and TGF-β in pancreatic inflammatory cells, and increased apoptosis among pancreatic acinar cells for the HLG(P < 0.05). Compared with the HLG, we found reduced body weight, Lee's index scores, serum triglyceride levels, and pathological scores for pancreatic tissues; higher serum adiponectin levels; and lower expression levels of NF-κB, in pancreatic tissue and TGF-β in pancreatic inflammatory cells for the HSG(P < 0.05). The in vitro studies showed enhanced PSC activation and increased expression levels of fibronectin and type I collagenase after SJP treatment. An adenosine 5‘-monophosphate-activated protein kinase(AMPK) inhibitor inhibited PSC *** SJP may ameliorate obesity-induced pancreatic inflammatory injury in rats by regulating key molecules of the

[Objective]To investigate the population genetic structure of Keerqin fine wool sheep. [Method]The genetic parameters of wool traits in Keerqin fine wool sheep were calculated by employing paternal half sib correlation method. [Results]The traits with high heritability( h≥0. 3) included wool length( 1-year old),wool yield( 1-year old) and wool yield( 2-year old); that with medium heritability( 0. 1≤h≤0. 3) included wool fineness( 1-year old),wool fineness( 2-year old),wool length( 3-year old) and wool yield( 3-year old). There were extremely significant positive correlations between wool fineness( 1-year old) and wool fineness( 2-year old),between wool fineness( 1-year old) and wool fineness( 3-year old),between wool length( 1-year old) and wool length( 2-year old),between wool length( 1-year old) and wool length( 3-year old),and between wool fineness( 2-year old) and wool fineness( 3-year old),with the correlation coefficients of 0. 653 0,0. 625 8,0. 489 6,0. 578 8,0. 578 4 and 0. 554 6 respectively. The results showed that the phenotypic correlation was poorer than genetic correlation among the wool traits. [Conclusion]The wool fineness,wool yield and body weight of Keerqin fine wool sheep all fail to meet the excellent level and need to be improved further.
