AIM: To investigate the state of infection, replication site, pathogenicity and clinical significance of transfusion transmitted virus (TTV) in patients with hepatitis, especially in patients of unknown etiology. METHODS: Liver tissues taken from 136 cases of non-A non-G hepatitis were tested for TT virus antigen and nucleic acid by in situ hybridization (ISH) and nested-polymerase chain reaction (PCR). Among them, TT virus genome and its complemental strand were also detected in 24 cases of autopsy liver and extrahepatic tissues with ISH. Meanwhile, TTV DNA was detected in the sera of 187 hepatitis patients by nested-PCR. The pathological and clinical data of the cases infected with TTV only were analyzed. RESULTS: In liver, the total positive rate of TTV DNA was 32.4% and the positive signals were located in the nuclei of hepatocytes. In serus, TTV DNA was detected in 21.4% cases of hepatitis A-G, 34.4% of non-A non-G hepatitis and 15% of healthy donors. The correspondence rate of TTV DNA detection between liver tissue with ISH and sera with PCR was 63.2% and 89.3% in the same liver tissues by ISH and by PCR, *** double-strand probes and single-strand probes designed to detect TTV genome, the correspondence rate of TTV DNA detected in liver and extrahepatic tissues was 85.7%. Using single-strand probes, TTV genome could be detected in liver and extrahepatic tissues by PCR, but its complemental strands (replication strands) could be observed only in livers. The liver function of most cases infected with TTV alone was abnormal and the liver tissues had different pathological damage such as ballooning, acidophilia degeneration, formation of apoptosis bodies and focus of necrosis, but the inflammation in the lobule and portal area was mild. CONCLUSION: The positive rate of TTV DNA among cases of hepatitis was higher than that of donors, especially in patients with non-A non-G hepatitis, but most of them were coinfected with other hepatitis viruses.

慢性乙型肝炎功能性治愈的定义是在停止抗病毒治疗后至少24周,HBsAg<0.05 IU/mL,血清HBV DNA<10 IU/mL。这需要抑制HBV复制、降低病毒抗原产生,同时恢复对HBV感染的免疫应答。约30%~50%接受核苷(酸)类似物治疗并经严格选择的慢性乙型肝炎患者,加用或单用聚乙二醇干扰素α治疗,或经核苷(酸)类似物有限疗程治疗后HBsAg<100 IU/mL者,可获得功能性治愈。目前有40余种新的抗HBV药物和免疫调节剂正在进行临床试验。抑制HBV复制、降低病毒抗原,以及提高HBV感染免疫应答药物的联合应用,可能是慢性乙型肝炎功能性治愈的理想治疗策略。但确定最佳的联合、用药时间、用药顺序和治疗期限等尚需进一步研究。

ICA-Net: improving class activation for weakly supervised semantic segmentation via joint contrastive and simulation learning

引用

Optoelectronics Letters 2025年第3期21卷 188-192页

作者： YE zhuang LIU Ruyu SUN Bo School of Information Engineering Chengdu Aviation Vocational and Technical College School of Computer Science and Engineering Hangzhou Normal University Quanzhou Institute of Equipment Manufacturing Haixi Institutes Chinese Academy of Sciences

In the field of optoelectronics, certain types of data may be difficult to accurately annotate, such as high-resolution optoelectronic imaging or imaging in certain special spectral ranges. Weakly supervised learning can provide a more reliable approach in these situations. Current popular approaches mainly adopt the classification-based class activation maps (CAM) as initial pseudo labels to solve the task.
