数据说明

Conditions: Cirrhoses, Liver, Decompensated Cirrhosis of Liver. Cirrhosis of liver accounts for approximately 1 million deaths per year. In addition to its clinical burden, it causes significant morbidity, impairment of health-related quality of life (HRQL), and economic burden (Younossi et al. 2023). It is the final pathway for a wide variety of chronic liver diseases, a pathologic entity defined as diffuse hepatic fibrosis with the replacement of the normal liver architecture by nodules (Feldman et al. 2015). It is currently the 9th leading cause of death in South East Asia and Europe; 10th leading cause of death in Africa ; and the 5th leading cause of death in the Eastern Mediterranean (Devarbhavi et al. 2023). According to World Health Organization, cirrhosis of liver is the 〖10〗^th leading cause of death in Bangladesh for both male and female (World Health Organization , 2021). Alcohol consumption, chronic hepatitis C infection, and NAFLD are the most common causes of cirrhosis in Western countries, while chronic hepatitis B is the predominant cause in the Asia-Pacific region. Other causes include inherited conditions like hemochromatosis and Wilson’s disease, along with primary biliary cholangitis, primary sclerosing cholangitis, and autoimmune hepatitis. In some cases, the cause of cirrhosis is unknown or cryptogenic (Zhou et al. 2014). Cirrhosis is classified in two main prognostic stages: compensated and decompensated cirrhosis. Decompensation means cirrhosis with one of the following: ascites, bleeding varices, hepatic encephalopathy or jaundice. Median survival in the compensated stage exceeds 12 years where as it is only 2 years in patients who develop decompensation (D’Amico et al. 2006). Cirrhosis advances from a compensated stage to a decompensated stage at a rate of 5%-7% annually (Kaur et al. 2025). The gut-liver axis functions as a crucial system that helps protect the body from potentially harmful substances and microorganisms, while also preserving the balance and stability of the immune system (Ponziani et

数据加载示例（图像类）

from PIL import Image
import glob, os

files = (glob.glob(os.path.join(path, "**", "*.png"), recursive=True)
       + glob.glob(os.path.join(path, "**", "*.jpg"), recursive=True)
       + glob.glob(os.path.join(path, "**", "*.tif"), recursive=True))
print("图像文件数:", len(files))
img = Image.open(files[0]); print("尺寸/模式:", img.size, img.mode)

# torchvision Dataset 方式:
# from torchvision import datasets
# ds = datasets.ImageFolder(path)  # 要求 子目录=类别
