概括
炎症在肝病回归中持续存在,即使在原因被消除后,也会导致门门高血压. 这种持续的炎症对门口压力的影响比静态肝脏变化更大.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 免疫学 免疫学 免疫学
- 胃肠病学 胃肠病学
背景情况:
- 门高血压 (PH) 导致肝脏并发症,即使在解决病因因素后也会持续存在.
- 静态和动态的肝内变化是PH的关键驱动因素.
- 了解疾病回归期间的PH动态对于管理肝病至关重要.
研究的目的:
- 为了研究炎症在肝病回归期间对门高血压 (PH) 的动态成分的影响.
- 在毒素诱导的肝硬化和与酒精有关的肝硬化的人类患者的动物模型中评估PH动态.
- 探索在疾病回归过程中促炎标志物和门压之间的关系.
主要方法:
- 通过毒素诱导小鼠肝硬化,然后在毒素撤销后进行回归期.
- 128名与酒精相关的肝硬化和禁酒患者同时接受了肝静脉压梯度 (HVPG) 和肝硬度测量 (LSM).
- 线性模型评估了炎症对动态PH成分的影响,将测量的压力与静态成分 (小鼠的原比例面积,患者的LSM) 预期的压力进行比较.
主要成果:
- 在小鼠中,毒素停止降低了门压 (PP),炎症和促炎性基因表达.
- 在患者中,酒精戒断与较低的HVPG/LSM和减少的炎症标志物 (CRP,IL-6,IgA,IgG) 相相关.
- 在小鼠和患者中,持续的低级炎症状态与高于预期的PP/HVPG有关,这表明炎症在动态PH中的作用.
结论:
- 消除病因因子可以改善肝病,但持续的肝炎性环境仍然是动态PH的重要驱动因素.

01:24Esophageal Varices-I: Introduction
72
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

01:24Chronic Pancreatitis I: Introduction
71
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

01:17Gastritis-II: Pathophysiology
242
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

01:28Esophageal Varices-II: Clinical Features and Management
46
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...
