A series of paeonol derivatives have been synthesized by simple acylation and etherification of the paeonol. Anti-tumor activities of the synthesized compounds were evaluated against HeLa and MCF-7 cells lines in vitro by the standard MTT assay. It was found that the derivatives were more active against HeLa than MCF-7. The results also indicated that 4-methoxy group is the synergistic group of paeonol's anti-tumor activity and ketone carbonyl side chain is essential functional group of paeonol's anti-tumor activity. Compound 2d had stronger antiproliferative activities than paeonol against HeLa and MCF-7 cell lines with IC50 values of 2.67 and 4.74 micromol x L(-1) respectively. The results showed that paeonol derivatives were worth to be intensively studied further.

ObjectiveTo observe the clinical efficacy and safety of traditional Chinese medicine （TCM） triple therapy in the treatment of spontaneous bacterial peritonitis （SBP） with damp-heat stagnation and toxin-blood stasis syndrome in liver cirrhosis patients， and to explore its potential mechanisms of action. MethodsEighty-six patients were randomly divided into the experimental group and the control group， with 43 patients in each group. Both groups received standard western medicine treatment， while the experimental group additionally received TCM triple therapy， including oral Qingre Liangxue Jiedu Decoction （清热凉血解毒汤）， retention enema with Dachengi Decoction （大承气汤）， and abdominal application of Qingre Zhitong Lishui Fomulation （清热止痛利水方） with lotus leaf. Both groups were treated for 2 weeks. Before and after treatment， various indicators were measured， such as TCM syndrome scores， ascites volume measured by abdominal ultrasound， liver function indicators including total bilirubin （TBIL）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， and albumin （ALB）， infection markers， including neutrophil percentage （NEUT%）， C-reactive protein （CRP）， and procalcitonin （PCT）， inflammatory factors， such as tumor necrosis factor-alpha （TNF-ɑ）， interleukin-6 （IL-6）， and interleukin-10 （IL-10）， intestinal mucosal barrier function markers， including endotoxin （ET）， diamine oxidase （DAO）， D-lactic acid （D-Lac）， occludin， and zonula occludens-1 （ZO-1）， and peritoneal polymorphonuclear （PMN） cell counts at 72 hours post-treatment. ResultsA total of 82 patients were included in the final analysis， with 41 patients in each group. The total effective rate for TCM syndrome in the experimental group was 92.68% （38/41）， which was significantly higher than the 80.49% （33/41） in the control group （P＜0.05）. Compared with pre-treatment values， both groups showed significant reductions in TCM syndrome scores， ascites volume， TBIL， ALT， AST， NEUT%， CRP， PCT， TNF-α， IL-6， ET， DAO， D-Lac， Occludin， and ZO-1， with an increase in IL-10 levels and a decrease in PMN count in ascites 72 hours post-treatment （P＜0.05）. Furthermore， the experimental group outperformed the control group in all the above indicators after treatment （P＜0.05）. The disappearance time of fever and abdominal pain was shorter in the experimental group than in the control group （P＜0.01）. There were no significant changes in routine urine and stool tests， renal function， electrolytes， or electrocardiogram in either group compared with pre-treatment values. ConclusionTCM triple therapy in addition to western medicine routine treatment could significantly improves clinical symptoms in patients with liver cirrhosis and SBP with damp-heat stagnation and toxin-blood stasis syndrome， alleviates liver inflammation， improves liver function， accelerates the resolution of ascites， and increases clinical efficacy. The potential mechanism may be related to the regulation of the inflammatory response and the promotion of intestinal mucosal barrier repair.

The sirtuin family of deacetylases widely exists in human cells and can regulate the post-translational chemical modification of various proteins by acting on mitochondria, endoplasmic reticulum and nucleus, thereby influencing the process of biological metabolism. The sirtuin family is also involved in a variety of pathophysiological reactions in nonalcoholic fatty liver disease (NAFLD). This article reviews the research advances in the association between the sirtuin family of deacetylases and nonalcoholic fatty liver disease, so as to provide a potential approach for NAFLD treatment in the future.

Pancreatogenic diabetes is a type of diabetes secondary to pancreatic exocrine disease,and it was officially named by American Diabetes Association in 2014.Chronic pancreatitis and pancreatic cancer are the most common causes of pancreatogenic diabetes.The pathogenesis of this disease remains unclear,and there is still a lack of systematic treatment regimens,which leads to the extremely high misdiagnosis rate of pancreatogenic diabetes in China and globally.In addition,studies have shown that compared with patients with type 2 diabetes,patients with pancreatogenic diabetes tend to have higher risks of death and readmission,which brings great challenges to the health and clinical treatment of patients.Therefore,the comprehensive understanding and early accurate identification and diagnosis of pancreatogenic diabetes are of great significance in reducing the disability and mortality rates of this disease.This article elaborates on the possible pathogenesis of pancreatogenic diabetes.

Hepatocellular carcinoma (HCC) is the most common type of liver cancer in China, and the development and progression of HCC is a complex pathological process. As a new way of cell death, ferroptosis has huge potential in the treatment of HCC. This article introduces the mechanism of action of the tumor suppressor p53 in regulating ferroptosis and briefly describes its role in the development and progression of HCC. The tumor suppressor p53 can promote or inhibit ferroptosis by affecting solute carrier family 7 member 11, spermidine/spermine N1-acety-ltransferase 1, glutaminase 2, dipeptidyl peptidase 4, and cyclin-dependent kinase inhibitor 1A, which in turn affects the progression of HCC. The treatment of HCC by regulating the ferroptosis pathway has great application prospects.

Amyloid protein （AP） is used to describe the fibrous aggregates that form when proteins are misfolded， and it is associated with a series of amyloidosis diseases. When AP is deposited in the liver， it will lead to liver amyloidosis， thereby inducing related pathological changes that affect the normal physiological function of the liver； however， this disease is rarely reported and often neglected in clinical practice. This article reviews the physiological and pathological effects and mechanisms of AP in the liver， so as to improve the understanding of AP-related diseases and provide a reference for related research and clinical treatment.

Objective To observe the feasibility of cardiac MR tissue tracking(CMR-TT)technique for quantitatively evaluating myocardial strain of patients with myocardial amyloidosis(CA).Methods Cardiac MRI were collected from 20 patients of immunoglobulin amyloid light-chain CA(AL-CA,group A),20 cases of transthyretin CA(ATTR-CA,group B)and 20 healthy subjects(group C),and myocardial strain parameters were obtained using CMR-TT technique.Left ventricular cardiac function parameters were compared among 3 groups,so were strain parameters of each myocardial segment of left ventricle and global myocardium,including 3D longitudinal strain(LS),3D radial strain(RS)and 3D circumferential strain(CS).Results Compared with those in group C,significant differences of left ventricular cardiac function parameters were found in both group A and B(all P＜0.01),while no statistical difference was found between group A and B(all P＞0.05).Except for apical segment RS(P=0.81),strain parameters in group A and B were both lower than those in group C(all P＜0.01),while no significant difference was detected between group A and B(all P＞0.05).Conclusion CMR-TT technique could be used to quantitatively evaluate left ventricular myocardial strain of CA patients.

Radiation-induced liver disease （RILD）， also known as radiation hepatitis， is subacute liver injury induced by radiation. As the focus of senescence-related studies， the deacetylase family Sirtuins （SIRTs） have the molecular functions including DNA repair and chromatin regulation， which makes SIRTs a hub for regulating genome and epigenome stability. Radiation-induced hepatic DNA damage and reaction is the primary physiological and pathological process of RILD， which is similar to the function of SIRTs. This article briefly introduces the structure and function of the SIRTs protein family， elaborates on the basic concepts and progress of the physical physiology of radiation therapy， discusses the internal relationship between SIRTs and RILD from the perspective of radiobiology， and points out the possibility of SIRTs as a target for the prevention and treatment of RILD.

Hepatic fibrosis is a pathological reparative response of the liver to chronic injury and a crucial step in the progression of chronic liver disease， characterized mainly by the activation of hepatic stellate cells and diffuse deposition of extracellular matrix. Currently， there is no ideal specific drug for the treatment of liver fibrosis in clinical practice. In recent years， with the development and progress of traditional Chinese medicine （TCM） in the treatment of liver fibrosis， TCM has been widely recognized for its significant therapeutic effect and fewer adverse reactions. The phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway is an important pathway that affects the formation and development of liver fibrosis. It mainly plays a role in liver fibrosis by inhibiting the activation and proliferation of hepatic stellate cells， promoting their apoptosis， reducing oxidative stress in liver cells， decreasing the deposition of extracellular matrix， and enhancing liver cell autophagy. This article summarized the mechanisms by which Chinese medicinal monomers regulated the PI3K/Akt pathway to exert their effects on liver fibrosis and their synergistic effects with other signaling pathways， providing a theoretical basis and references for the development of new drugs for the treatment of liver fibrosis with TCM.

Hepatocellular carcinoma （HCC） is one of the common malignant tumors of the digestive tract and seriously threatens the life of patients due to a high incidence rate， a high degree of malignancy， strong invasion and metastasis， and poor prognosis. At present， the main methods for the prevention and treatment of HCC include drugs， surgery， and interventional treatment， but all of these methods have certain adverse reactions and side effects. As an important intracellular signal transduction pathway in the human body， the JAK/STAT signaling pathway mainly exerts an anti-HCC effect by regulating cell invasion， metastasis， proliferation， growth， apoptosis， autophagy， angiogenesis， inflammation/immune response， iron metabolism， and drug resistance. Therefore， targeting the JAK/STAT signaling pathway plays an important role in the prevention and treatment of the development and progression of HCC. Traditional Chinese medicine has attracted wide attention due to its advantages of multiple targets， pathways， components， and levels in the treatment of HCC， and many cell or animal experiments on traditional Chinese medicine in the treatment of HCC have shown that the JAK/STAT signaling pathway is an important target for the prevention and treatment of HCC， with the effects of improving liver function， reducing HCC recurrence， and improving immunity. Based on this， this article analyzes the mechanism of action of the JAK/STAT signaling pathway in HCC， as well as the intervention effect of traditional Chinese medicine monomers， traditional Chinese medicine extracts， and traditional Chinese medicine compounds on the JAK/STAT signaling pathway， in order to provide theoretical basis and reference for the prevention and treatment of HCC and the research and development of new traditional Chinese medicine drugs.
