[Objectives]This study aimed to study the effects of Shenge Yifei capsule on the TGF-β1/Smad signaling pathway in rats with chronic obstructive pulmonary disease(COPD).[Methods]Ten rats were randomly selected as the control group,and the other 40 rats were selected for modeling by fumigation combined with Klebsiella pneumoniae infection.A total of 38 rats were successfully modeled.They were randomly divided into model group(8 rats),low-dose Shenge Yifei capsule group(10 rats),high-dose Shenge Yifei capsule group(10 rats)and theophylline group(10 rats)in accordance with the principle of half male and half female.The rats in the model and control groups were given with distilled water by gavage,and the rats in the drug administration groups were given with corresponding drugs.The TGF-β1 level in the serum,and the expression levels of TGF-β1,Smad2,Smad3 and Smad7 and TGF-β1,Smad3 and Smad7 in airway tissues were detected.[Results]After 12 weeks,the serum TGF-β1 levels of the theophylline group and high-dose Shenge Yifei capsule group were lower than that of the low-dose Shenge Yifei capsule group(P<0.05).The expression levels of TGF-β1 and Smad3 in the theophylline group and high-dose Shenge Yifei capsule group were lower than that in the low-dose Shenge Yifei capsule group(P<0.05).The expression levels of TGF-β1 and Smad3 in the high-dose Shenge Yifei capsule group were lower than those in the low-dose Shenge Yifei capsule group and theophylline group(P<0.05).The expression levels of Smad7 and the proteins in the model group were lower than those in the other groups(P<0.05).The expression levels of Smad7 in the theophylline group and high-dose Shenge Yifei capsule group were higher than that in the low-dose Shenge Yifei capsule group(P<0.05).After 18 weeks,no significant difference was found in serum TGF-β1 level among the theophylline group and low and high-dose Shenge Yifei capsule groups(P>0.05).The expression levels of Smad7 and the proteins in the model group were lower than those in the other groups.The expression level of Smad7 in the high-dose Shenge Yifei capsule group was lower than that in the theophylline group(P<0.05).[Conclusions]Shenge Yifei capsule can regulate the TGF-β1/Smads signaling pathway.They can down-regulate the expression of TGF-β1,Smad2 and Smad3 and up-regulate the expression of Smad7,reducing the degree of airway modeling,delaying the development of COPD disease.Conventional high-dose Shenge Yifei capsule is more effective in inhibiting the expression of Smad2. 展开更多

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 diet.AIM 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 diet.METHODS 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.RESULTS 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 in the pancreas, heart, spleen, lung, and liver; myeloperoxidase expression levels in the lung; and pathological scores in the liver.CONCLUSION Obesity may aggravate the inflammatory reaction and pathological multipleorgan injury in AP rats, and SJP may alleviate multiple-organ inflammatory injury in AP in rats fed a high-fat diet. 展开更多

The translation of this masterpiece exposes a most difficult task for translators. The author picks out two well-accepted translated versions:one is Ruo Jingguo's Ode To The Sound Of Autumn and L. Cranmer-Byng's Autumn, as the author sees it, they are the typical example of semantic translation and communicative translation of the source text respectively. From this perspective, the writer aims to make a comparative study and demonstrate the differences between the two. 展开更多

AIM To investigate the mechanisms by which Sheng-jiang powder(SJP) ameliorates obesity-induced pancreatic inflammatory injury.METHODS 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 assessed.RESULTS 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 activation.CONCLUSION SJP may ameliorate obesity-induced pancreatic inflammatory injury in rats by regulating key molecules of the adiponectin-AMPK signalling pathway. 展开更多

Since the advent of the cultural turn in translation studies in the 1970s, the focus of translation studies has been shifted to the subjectivity of translators. This paper attempts to make a tentative probe into the translator's subjectivity manifested in the translation of Fu Sheng Liu Ji by Shen Fu on the basis of George Steiner's fourfold translation motion theory, namely"trust", "aggression","incorporation"and"compensation". By the study, we may obtain scientific understanding of how the translation is shaped by the translator's subjectivity, thus affirming the importance and necessity of the later in literary translation. 展开更多
