Esophageal variceal bleeding is a major complication of liver cancer and a major cause of death in patients with liver cancer.This article summarizes the current status of the treatment of liver cancer complicated by esophageal variceal bleeding, including drugs and endoscopic and interventional treatment, with an emphasis on treatment options for liver cancer complicated by esophageal variceal bleeding.

Multi-species solid-state fermentation in a mud pit is one of the typical features of strong-flavor baijiu, in which archaea plays important roles, however, the archaeal community distribution and diversity during fermentation are still lack of research. The biomass, composition and succession of archaea communities in fermented grains and pit mud were analyzed by high throughput sequencing. The potential interaction between archaea and bacteria was analyzed by co-occurrence network. Results demonstrate that the average biomass of archaea in pit mud was about 200 times higher than that of fermented grains. There was no significant difference in archaeal community structure between fermented grains and pit mud (r=0.017, P=0.074), but succession patterns between them showed significant correlation (r=0.30, P=0.03). Methanobacterium was the most abundant archaea in fermented grains and pit mud, and other dominant groups included Methanosarcina, Methanocorpusculum, Methanoculleus, and Methanobrevibacter. The co-occurrence network analysis showed that Methanobacterium was positively correlated with most bacteria in fermented grains and pit mud, especially with Hydrogenispora and Caproiciproducens, the dominant bacteria in pit mud. Our results revealed the temporal and spatial distribution characteristics and potential functions of the archaeal community in the mud pit of strong-flavor baijiu.

Oxidative stress, due to the disruption of the balance between reactive oxygen species (ROS) generation and the antioxidant defense system, plays an important role in the pathogenesis of rheumatoid arthritis (RA). Excessive ROS leads to the loss of biological molecules and cellular functions, release of many inflammatory mediators, stimulate the polarization of macrophages, and aggravate the inflammatory response, thus promoting osteoclasts and bone damage. Therefore, foreign antioxidants would effectively treat RA. Herein, ultrasmall iron-quercetin natural coordination nanoparticles (Fe-Qur NCNs) with excellent anti-inflammatory and antioxidant properties were constructed to effectively treat RA. Fe-Qur NCNs obtained by simple mixing retain the inherent ability to remove ROS of quercetin and have a better water-solubility and biocompatibility. In vitro experiments showed that Fe-Qur NCNs could effectively remove excess ROS, avoid cell apoptosis, and inhibit the polarization of inflammatory macrophages by reducing the activation of the nuclear factor-κ-gene binding (NF-κB) pathways. In vivo experiments showed that the swollen joints of mice with rheumatoid arthritis treated with Fe-Qur NCNs significantly improved, with Fe-Qur NCNs largely reducing inflammatory cell infiltration, increasing anti-inflammatory macrophage phenotypes, and thus inhibiting osteoclasts, which led to bone erosion. This study demonstrated that the new metal-natural coordination nanoparticles could be an effective therapeutic agent for the prevention of RA and other diseases associated with oxidative stress.

Ankylosing spondylitis (AS) combined with spinal fractures with thoracic and lumbar fracture as the most common type shows characteristics of unstable fracture, high incidence of nerve injury, high mortality and high disability rate. The diagnosis may be missed because it is mostly caused by low-energy injury, when spinal rigidity and osteoporosis have a great impact on the accuracy of imaging examination. At the same time, the treatment choices are controversial, with no relevant specifications. Non-operative treatments can easily lead to bone nonunion, pseudoarthrosis and delayed nerve injury, while surgeries may be failed due to internal fixation failure. At present, there are no evidence-based guidelines for the diagnosis and treatment of AS combined with thoracic and lumbar fracture. In this context, the Spinal Trauma Academic Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate the Clinical guideline for the diagnosis and treatment of adult ankylosing spondylitis combined with thoracolumbar fracture ( version 2023) by following the principles of evidence-based medicine and systematically review related literatures. Ten recommendations on the diagnosis, imaging evaluation, classification and treatment of AS combined with thoracic and lumbar fracture were put forward, aiming to standardize the clinical diagnosis and treatment of such disorder.
