ABSTRACT
Cholestatic liver diseases (CLD) are a series of hepatobiliary diseases characterized by dysfunction of bile formation, secretion and excretion and are induced by immune, genetic and environmental factors. The development and pathogenesis of CLD is still unclear, and it has a risk of progression to liver fibrosis and cirrhosis. Traditional medicines such as ursodeoxycholic acid (UDCA), glucocorticoids and immunosuppressants have certain limitations. More and more studies provide new insights into the mechanism of cholestasis to explore the therapeutic targets, and various drugs such as all-trans retinoic acid, microecologics and norursodeoxycholic acid emerge as new therapeutic drugs. This article reviewed the advances in treatment of CLD.
ABSTRACT
With the changes in people’s lifestyle and dietary structure, the incidence rate of nonalcoholic fatty liver disease (NAFLD) has been increasing year by year, and NAFLD has become a serious threat to human health. The treatment of NAFLD has always been a hot topic of basic and clinical research on liver diseases. In recent years, many studies have revealed that omega-3 polyunsaturated fatty acids (ω3-PUFA) can promote fatty acid oxidation, improve intestinal homeostasis, and thus improve lipid metabolism and liver inflammation, and therefore, more and more clinical studies have applied ω3-PUFA in the treatment of NAFLD. However, the mechanism of ω3-PUFA in the treatment of NAFLD is still unclear, and there are certain limitations in related clinical studies. This article mainly introduces the role of ω3-PUFA in NAFLD and the results of related clinical studies and further discusses the problems that need to be solved in ω3-PUFA for the treatment of NAFLD.
ABSTRACT
Non-alcoholic fatty liver disease (NAFLD) is a liver manifestation of the metabolic syndrome. The "second strike" theory implies that cytokines play vital roles in the pathogenesis of NAFLD. Tumor necrosis factor-α (TNF-α), an important member of the tumor necrosis factor family, is widely available and has various biological effects. The expression of TNF-α in vivo is tissue-specific and participates in various cellular activities. Low concentration of TNF-α is involved in anti-inflammation, while excessive TNF-α impairs systematic immune balance and contributes to pathological changes along with other inflammatory cytokines. This article reviewed the role of TNF-α in progression of NAFLD.
ABSTRACT
Liver fibrosis is a common reversible pathological change in chronic liver injury and may progress to liver cirrhosis, liver failure, and portal hypertension. In recent years, several studies have shown a significant change in chemokine profiles in patients with liver fibrosis, which is closely associated with the progression of liver fibrosis. Monocyte chemoattractant protein 1 (MCP-1) belongs to the family of CC chemokines and can induce the activation, recruitment, and migration of inflammatory cells during liver fibrosis. MCP-1 may be involved in the activation of hepatic stellate cells, the development of insulin resistance, and the progression to hepatocellular carcinoma. This article mainly reviews the potential role of MCP-1 and CC chemokine receptor in the progression of liver fibrosis and related therapies.
ABSTRACT
Objective To observe the temporomandibular joint spaces changes after the plastic surgery of combined zygoma with mandibular angel.Methods We randomly selected 59 patients with prominent zygoma and mandibular angle,screening periodontal disease,TMJ pain and partial jaw.Bilateral zygomatic arch coarctation,jaw edge of the mandibular angle ostectomy and the mandibular body outer panel split were used.All patients accepted CT scan and three-dimensional reconstruction before operation,10 days after operation and 6 months after operation,and then image analysis softwares were used to measure the line distance of corresponding angle (0°,60°,120°,and 180°)at the TMJ sagittal plane.The 0° (EE 'pitch) and 60° (AA'pitch) represented for pre-space,the 60° and 120° (PP'pitch) was upper-space,the 120° and 180° (SS'pitch) was posterior-space.Results 0° and 60° had the same change trend,which slightly increased at 10 days after operation.The difference before operation and 10 days,6 months after operation were not statistically significant (P ＞ 0.05);120° and 180° had the same change trend,which increased at 10 days after operation.The difference between before operation and 10 days after operation was statistically significant (P ＜ 0.05),but the difference between before operation and 6 months after operation was not statistically significant (P＞ 0.05).Conclusions In the short term after plastic surgery of zygoma combined with mandibular angel,the TMJ upper and posterior spaces are changed,and the interspace reduced.This may indicate that the TMJ has compensatory ability,and short-term changes can return to normal.
