ABSTRACT
Liver fibrosis is a chronic liver injury caused by various etiologies and a complex pathological change with the activation of hepatic stellate cells as the central link, and various signaling pathways are involved in the regulation of such complex lesions. It has the dual nature of repair and damage and may eventually progress to liver cirrhosis, liver failure, and even liver cancer. In recent years, rapid progress has been made in the basic research on the cell signal transduction pathways associated with liver fibrosis, and some achievements have been made in the research on the treatment strategy of liver fibrosis. This article briefly reviews the cell signaling pathways associated with the development of liver fibrosis, including the JAK/STAT signaling pathway, the NF-κB signaling pathway, the MAPK signaling pathway, the TGF-signaling 1/Smad signaling pathway, the Wnt signaling pathway, the Hedgehog signaling pathway, and the Notch signaling pathway, and also introduces the potential therapeutic strategies for liver fibrosis at present.
ABSTRACT
Objective To evaluate the clinical efficacy and safety of ritonavir-boosted danoprevir (DNVr) combined with daclatasvir (DCV) in the treatment of patients with genotype 1b chronic hepatitis C (CHC).Methods Thirty-three patients with genotype 1b CHC admitted in the Department of Infectious Diseases of the First Affiliated Hospital of Nanchang University from August 2018 to February 2019 were enrolled.All the patients received DNVr +DCV antiviral treatment.HCV RNA levels were detected before and 2, 4, 12 weeks after treatment, and after drug withdrawal , respectively.Indicators of liver and kidney function and adverse events were observed.ANOVAV of repeated measurement was used to analyze the data. Results The baseline viral loads of 33 patients ranged from 1.12×104 to 1.76×107 IU／mL.Two weeks after treatment the viral loads of all patients were down to the lowest limit of detection (＜500 IU／mL). Serum ALT, AST and TBil levels returned to norml ( F＝58.26, 14.49 and 20.16, all P＜0.05) and sustained virologic response reached 100%12 weeks after drug withdrawal.Three cases had minor adverse reactions during the treatment.Conclusion DNVr combined with DCV can achieve a rapid and strong virological response in the treatment of patients with genotype 1b CHC with good safety.
ABSTRACT
This article sumed up the therapeutic principle and treatments of ‘toxin' in Treatise on the Causes and Manifestation of Diseases,including sterilizing,alexipharmacon,Daoyin technique,perspiration,vomiting,inducing stool and vomiting,and external treatment.These treatments offered theoretical evidence for clinical treatment.
