Comparison of Liver diseases between Japan and China using Screenig of Ultrasonography

肝细胞癌（HCC）在亚洲是一个高发病率的疾病.为了减少该病的死亡，日本推荐通过超声筛查进行早期诊断，但在中国仍未推荐。本研究是济济医学院与北京医科大学在肝癌高危人群中开展的超声筛查研究。北京市居民共检查18604例，其中高危组11284例，对照组4526例，随访组2254例。高危组发现肝癌10例（0.86%），门诊组发现肝癌97例（0.96%），对照组未发现肝癌。这些结果与日本的结果一致。超声引导穿刺55例以上，明确病理诊断。肝硬化慢性肝损害随访发现肝癌10例（1.2%）。肝癌的早期诊断在我国已初步建立，本研究将为肝癌的进一步研究奠定基础。

Hepatocellular carcinoma (HCC) is known to be suffered high population in Asia. To reduce the death of this disease, early diagnosis by ultrasonic screening is recommended in Japan, but still not in China. This study is designed for ultrasonic screening to find HCC,as the co-research between Jichi Medical School and Beijing Medical University in high risk group. 18604 examinations were at the citizen in Beijing, the 11284 in high risk group, 4526 in control group, 2254 in follow up group. The HCC were found 10 cases (0.86%) in high risk group and 97cases (0.96%) in the out patient group, but not found in control group. These results were consistent with those in Japan. Ultrasonic guided puncture were in over 55 cases to identify the pathological diagnosis. The 1.2% (10/844 cases) of HCC were found in follow up study in chronic liver damage of liver cirrhosis. To establish of early diagnosis in HCC is yielded in China, and this study will be effective to make other or more advanced researches.
