Primary biliary cholangitis(PBC)is an autoimmune liver disease often observed in middle-aged women.The early clinical symptoms of PBC are not obvious,and it can progress to liver cirrhosis and lead to various complications.Ursodeoxycholic acid(UDCA)is the most effective drug for the treatment of PBC,but about 40%of the patients are still insensitive to UDCA,which can lead to slow progression of the disease.Accurate assessment of disease conditions and patient prognosis can help to optimize treatment regimens.This article reviews the research advances in prognostic models for PBC,in order to provide a reference for clinical treatment.

After ostomy surgery, patients lose the ability to control their anal sphincter, relying on ostomy pouches for excretion. Convex baseplates offer several advantages, including preventing leakage, reducing the risk of stoma and peripheral skin complications, and adapting to the dynamic stoma shapes caused by peristaltic expansion and contraction of the stoma. This article reviews the structure and features of convex baseplates, usage considerations, existing challenges, and future prospects, aiming to provide a reference for the standardized clinical use of convex baseplates and to improve patient health outcomes.

Temporomandibular joint osteoarthritis (TMJ-OA) is a common disease often accompanied by pain, seriously affecting physical and mental health of patients. Abnormal innervation at the osteochondral junction has been considered as a predominant origin of arthralgia, while the specific mechanism mediating pain remains unclear. To investigate the underlying mechanism of TMJ-OA pain, an abnormal joint loading model was used to induce TMJ-OA pain. We found that during the development of TMJ-OA, the increased innervation of sympathetic nerve of subchondral bone precedes that of sensory nerves. Furthermore, these two types of nerves are spatially closely associated. Additionally, it was discovered that activation of sympathetic neural signals promotes osteoarthritic pain in mice, whereas blocking these signals effectively alleviates pain. In vitro experiments also confirmed that norepinephrine released by sympathetic neurons promotes the activation and axonal growth of sensory neurons. Moreover, we also discovered that through releasing norepinephrine, regional sympathetic nerves of subchondral bone were found to regulate growth and activation of local sensory nerves synergistically with other pain regulators. This study identified the role of regional sympathetic nerves in mediating pain in TMJ-OA. It sheds light on a new mechanism of abnormal innervation at the osteochondral junction and the regional crosstalk between peripheral nerves, providing a potential target for treating TMJ-OA pain.

Hypoxemia is a common pathological state characterized by low oxygen saturation in the blood. This condition compromises mucosal barrier integrity particularly in the gut and oral cavity. However, the mechanisms underlying this association remain unclear. This study used periodontitis as a model to investigate the role of platelet activation in oral mucosal immunopathology under hypoxic conditions. Hypoxia upregulated methyltransferase-like protein 4 (METTL4) expression in platelets, resulting in N⁶-methyladenine modification of mitochondrial DNA (mtDNA). This modification impaired mitochondrial transcriptional factor A-dependent cytosolic mtDNA degradation, leading to cytosolic mtDNA accumulation. Excess cytosolic mt-DNA aberrantly activated the cGAS-STING pathway in platelets. This resulted in excessive platelet activation and neutrophil extracellular trap formation that ultimately exacerbated periodontitis. Targeting platelet METTL4 and its downstream pathways offers a potential strategy for managing oral mucosa immunopathology. Further research is needed to examine its broader implications for mucosal inflammation under hypoxic conditions.

Objective:To investigate the effect of Early infarct growth rate(EIGR) on the prognosis of patients with acute large vessel occlusive ischemic stroke.Methods:A total of 164 patients with acute large vessel occlusive ischemic stroke were enrolled in the emergency department of the First Affiliated Hospital of Nanjing Medical University from January 1, 2020 to December 31, 2022.According to the change of the National Institutes of Health Stroke Scale (NIHSS) score at admission and 72 h after treatment, the patients were divided into good prognosis group and poor prognosis group. The basic clinical data of the two groups were observed and compared. The risk factors of poor prognosis were analyzed by univariate regression. The effect of EIGR on prognosis after age stratification was further analyzed.Results:Comparing the clinical data of the two groups, there was no difference in EIGR (mL/h) (7.67 vs. 8.24, P=0.211) between the two groups. The product between EIGR and age was included as the interaction term, and the result of the interaction term in the model was statistically significant ( OR=1.002, 95% CI: 1.000-1.003, P=0.032) .Moreover, the result was still statistically significant after adjusting for relevant variables (gender, history of hypertension, history of atrial fibrillation, history of diabetes, history of coronary heart disease, and history of stroke) ( OR=1.002, 95% CI:1.000-1.003, P=0.027). Subgroup analysis was performed according to the median age (71 years). In the elderly group, the proportion of poor prognosis was higher with fast core infarction growth rate defined by 25 mL/h and 15 mL/h ( P < 0.05).In the younger age group, there was no significant difference in the proportion of poor prognosis in the fast core infarction growth rate compared with the slow type ( P > 0.05). Conclusions:EIGR can predict the early clinical outcome early in elderly patients with large vessel occlusive ischemic stroke.
