N-acetyl-p-aminophenol （APAP） is an antipyretic analgesic commonly used in clinical practice， and APAP overdose can cause severe liver injury and even death. In recent years， the incidence rate of APAP-induced liver injury （AILI） tends to increase， and it has become the second most common cause of liver transplantation worldwide. Autophagy is a highly conserved catabolic process that removes unwanted cytosolic proteins and organelles through lysosomal degradation to achieve the metabolic needs of cells themselves and the renewal of organelles. A large number of studies have shown that autophagy plays a key role in the pathophysiology of AILI， involving the mechanisms such as APAP protein conjugates， oxidative stress， JNK activation， mitochondrial dysfunction， inflammatory response and apoptosis. This article elaborates on the biological mechanism of autophagy in AILI， in order to provide a theoretical basis for the treatment of AILI and the development of autophagy regulators.

The incidence rate of drug-induced liver injury （DILI） is increasing year by year with unknown mechanisms， and the treatment methods for DILI mainly include drugs， liver support systems， and liver transplantation， all of which have certain limitations. Therefore， the search for safer and more effective treatment methods has become a research hotspot at present. Studies have shown that mesenchymal stem cells and their exosomes can alleviate liver injury by reducing liver inflammation， promoting hepatocyte proliferation and regeneration， inhibiting the apoptosis of hepatocytes， improving oxidative stress， and regulating immunity. This article briefly reviews the role of mesenchymal stem cells and their exosomes in the treatment of DILI， so as to provide a reference for further research.

In recent years, the number of patients with vaginal relaxation has increased year by year, and the minimally invasive vaginal contraction has been carried out more and more widely in clinical practice, but the treatment normalization and safety have not been thoroughly studied. We summarized six cases of characteristics and treatment measures for patients with various complications after minimally invasive vaginal contraction surgery from September 2021 to December 2023 at Department of Plastic and Aesthetic Surgery, Peking Union Medical College Hospital. The patients' age ranged from 26 to 44 years. Two cases accepted vaginal contraction with embedded vaginal thread, and four accepted vaginal contraction with acellular allogenic dermis. One patient showed vaginal hyper-tightness, one patient showed subcutaneous suture nodules, two patients showed explosion of acellular allogenic dermis, and three patients showed vaginal infection symptoms such as yellow leucorrhea and peculiar smell. All patients had sexual pain and discomfort. One patient underwent vaginal orifice dilation, one patient underwent suture extraction and secondary vaginal contraction, one patient underwent acellular allogenic dermis extraction and immediate vaginal contraction, two patients underwent acellular allogenic dermis extraction and secondary vaginal contraction, and one patient underwent secondary vaginal contraction. The symptoms of all six patients were relieved after treatment. Despite the short operation time and fast postoperative recovery of minimally invasive vaginal contraction, there are still complications after surgery, causing physical and mental damage to patients. Plastic surgeons, therefore, should be cautious in the treatment process to avoid collateral damage, so that patients get the best treatment effect.

Autoimmune hepatitis(AIH)is a type of chronic hepatitis caused by the attack of hepatocytes by the autoimmune system,and with the prolongation of disease course,it may gradually progress to liver cirrhosis and even hepatocellular carcinoma.Although great achievements have been made in the understanding and treatment of AIH,its etiology and pathogenesis still remain unclear.T cells play a crucial role in the development and progression of AIH,and by focusing on follicular helper T cells,this article elaborates on the research advances in follicular helper T cells in AIH,in order to provide new ideas and strategies for the clinical treatment of AIH.

Autoimmune hepatitis(AIH)is chronic hepatitis caused by the attack of live cells by the immune system,and at present,the pathogenesis of AIH remains unclear.Inflammasomes are important components of innate immunity and are involved in a variety of pathophysiological processes.Studies have shown that inflammatory response associated with nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)plays an important role in the pathogenesis of AIH,which mainly mediates the release of proinflammatory factors and pyroptosis,thereby participating in the pathophysiological process of AIH.Therefore,the development and progression of AIH can be delayed by inhibiting the activation of NLRP3 inflammasomes,which provides new ideas for the prevention and treatment of AIH.

As the guiding theory for the diagnosis and treatment of encephalopathy in traditional Chinese medicine （TCM）， The marrow sea theory has important theoretical connotation and clinical value. This paper summarized the clinical research literature on the differentiation and treatment of common encephalopathy based on the marrow sea theory published in recent years， analyzed the treatment method and effects from eight aspects in terms of stroke， dizziness， insomnia， headache， constraint syndrome， dementia， tremor syndrome， and atrophy syndrome， and discussed the possible mechanism based on the relevant basic research. It is believed that marrow sea depletion is the common pathogenesis of encephalopathy in TCM. Guided by the method of supplementing essence and boosting marrow， the corresponding formulas and medicinals are recommended in accordance with differentiated syndromes， which can effectively improve the symptoms of the disease， delay the progression， increase the daily life ability of the patients， and improve the quality of life. Based on the marrow sea theory， the method of supplementing essence and boosting marrow， rectifying healthy qi and dispelling pathogen can be used to highlight the advantages of TCM and provide ideas for the diagnosis and treatment of encephalopathy in TCM.

Programmed death-1 and programmed death-ligand 1(PD-1/PD-L1)are regulatory immune checkpoint molecules that inhibit T cell activation and,therefore,play an important role in tumor immunotherapy.In recent years,increasing numbers of targeted therapeutic agents have been developed,but single immune checkpoint blockers cannot completely inhibit tumor occurrence,and tumor escape sporadically occurs.Consequently,combination therapy of targeted drugs is considered a useful method to inhibit tumorigenesis and tumor development.T cell immunoglobulin and immunoreceptor tyrosine-based inhibition motif(ITIM)domain(TIGIT)is an inhibitory type 1 poliovirus receptor that has recently been a hotspot of targeted drug therapy research.It has been shown that the combination therapy of TIGIT plus PD-1/PD-L1 can reduce tumor escape and inhibit tumorigenesis more effectively.Therefore,this review summarizes and discusses the progress on the dual blockade of TIGIT and PD-1/PD-L1 pathways in tumor immunotherapy to provide a theoretical basis for tumor im-munotherapy.
