Acute-on-chronic liver failure (ACLF) is a group of clinical syndromes related to severe acute liver function damage and multiple organ failure caused by various acute inducing factors on the basis of chronic liver disease. Due to its serious condition, rapid progression and high mortality, it has attracted more and more attention. Recent studies have shown that the pathogenesis of ACLF mainly includes direct injury and immune injury. As the main immune cells in the liver, the immunoregulatory role of liver macrophages in ACLF has been increasingly recognized. Liver macrophages have excellent phenotype conversion function and plasticity characteristics under the influence of epigenetic reprogramming or local microenvironment. This adaptive expression ability can use key mediators to promote the early conversion of anti-inflammatory phenotype to alleviate liver injury. A large number of studies have shown that liver macrophages have a certain potential in reversing the process of ACLF. Therefore, from the perspective of the plasticity characteristics of liver macrophages, this paper expounds the role of liver macrophages in ACLF and the research on the intervention of ACLF disease process, and summarizes its potential significance in the treatment of ACLF.

Sjogren's syndrome is a refractory disease for which TCM demonstrates certain advantages in its treatment. "Prevalent dryness affecting the liver" is a classical theory from Huangdi Neijing (Huangdi's Internal Classic), which has important guiding significance for the treatment of Sjogren's syndrome with TCM. In this paper, the connotation and development of the theory of "prevalent dryness affecting the liver" is comprehensively analyzed in combination with clinical practice. Sjogren's syndrome is closely related to the liver itself, its functions, and the coordination between the liver and other viscera. The liver itself pertains to yin, and it nourishes blood and moistens dryness. The liver's functions pertain to yang, and they help to move body fluids without any sign of dryness. It's also of great significance that the liver and other viscera are well coordinated. In ancient books and modern studies, many clinical manifestations of Sjogren's syndrome, including anxiety and depression, are closely related to the liver. Therefore, the treatment methods based on regulating and soothing the liver are summarized, such as soothing the liver qi, clearing the liver heat and nourishing the liver yin, taking into account all the five zang organs, and dredging the channels and collaterals. Taking the theory of "prevalent dryness affecting the liver" as the breakthrough point, this paper systematically sorts out the onset, pathogenesis, pattern differentiation, and the significance of addressing the liver in the treatment of Sjogren's syndrome to provide reference for clinical practice.

Objective To summarize the clinical features of optic neuritis (ON) complicated with chronic hepatitis B virus (HBV) infection, and evaluate the effectiveness of different treatment regimens, recurrence of ON, visual prognosis, HBV reactivation, liver function and liver structure changes. Methods and Results Total 19 patients (23 eyes) with acute ON complicated with chronic HBV infection admitted to Beijing Tongren Hospital, Capital Medical University from January 2015 to June 2021 were included. There were 13 females and 6 males, 15 cases with monocular onset, 17 cases with unidirectional course of disease, and 6 cases with optic disc edema. The time to the worst visual acuity (peak time) was 3 (2, 7) d after onset, and 16/23 eyes had severe visual impairment. Enhanced MRI showed abnormal intensity in orbital, intraductal or intracranial segments of optic nerve, even involving optic nerve sheath and optic chiasm. Anti-nuclear antibody (ANA) was positive in 5 cases and A type Sjögren's syndrome antibody (SSA) was weakly positive in one case. Cerebrospinal fluid (CBF) pressure decreased in 1/7 cases and white blood cell count increased in 2/7 cases. HBV DNA positive group (HBV DNA ≥ 100 IU/ml, 10 cases and 11 eyes) had more severe visual impairment than negative group (HBV DNA < 100 IU/ml, 9 cases and 12 eyes), the difference was statistically significant (Fisher's exact probability: P = 0.005, 0.003). HBV DNA positive group was treated with entecavir, and the recurrence of ON was ignored during follow-up. HBV DNA negative group didn't receive antiviral therapy, one case progressed to cirrhosis, 3 cases had abnormal liver function, and 2 cases had HBV reactivation. Conclusions The visual function of patients with ON complicated with chronic HBV infection was seriously impaired, and the response to glucocorticoid therapy was not good. The visual impairment of patients with positive HBV DNA was more serious than patients with negative HBV DNA. Patients with ON complicated with chronic HBV infection should be treated with antiviral drugs in combination with glucocorticoid therapy. [ABSTRACT FROM AUTHOR]

Accurately and efficiently contour extraction for the liver CT image sequence is one of the key problems of the abdominal soft-tissue model reconstruction and visualization. This paper proposed a contour extraction method based on a priori knowledge model. Firstly, it employed the Laplace transformation algorithm for image enhancement, and then proposed lasso model based on a priori knowledge of edges for semi-automatic initialization. Finally, it extracted contours of the liver accurately by an improved Snake algorithm. Furthermore, after the first image extraction, it proposed to initialize other CT images automatically according to the correlation between sequence, i. e. extraction result of previous image was employed as the initialization points of the next image, and so on. In this way, it preformed the whole extraction in a very elegant batch fashion. The experimental results on both liver images and lung images show that the proposed algorithm greatly reduces the dependence on initializing accuracy while effectively solve the problem of the liver contour extraction.
