Objective:To improve the clinical recognition of hereditary fibrinogen deficiency.Methods:The diagnosis and treatment process of a patient with acute promyelocytic leukemia (APL) complicated with hereditary fibrinogen deficiency who was admitted to the second Affiliated Hospital of Anhui Medical University in December 2018 was retrospectively analyzed, and the relevant literature was reviewed.Results:The patient was initially diagnosed as APL, and the complete remission was obtained after dual-induction therapy of all-trans retinoid acid and arsenous acid. During the first consolidation treatment, repeated reviews of fibrinogen fluctuated between 1.0-1.5g/L, and further improving the fibrinogen gene sequencing to diagnose APL combined with hereditary fibrinogen deficiency.Conclusion:For APL patients in remission who have decreased fibrinogen for many times and patients with hereditary fibrinogen deficiency who have significantly decreased fibrinogen in a short period, bone marrow biopsy and genetic testing should be further conducted to determine the pathogenesis.

Immune cascade due to inflammasome has become a research hotspot in recent years, and the role of NLRP3 inflammasome in the development and progression of liver diseases has attracted more and more attention. This article analyzes the action characteristics and regulatory mechanism of NLRP3 inflammasome in liver diseases, such as viral hepatitis, liver fibrosis, nonalcoholic fatty liver disease, liver failure, and liver cancer, and establishes targeted therapy based on NLRP3 inflammasome to regulate immune response triggered by inflammasome, in order to provide new ideas for the prevention and treatment of liver diseases.

Bile acids (BAs) are produced in the liver and are the final product of cholesterol catabolism, with a wide range of biological effects. This article reviews the research advances in the synthesis, transport, and metabolism of BAs and the role of BAs in regulating hepatocytes and immunity via enterohepatic circulation, as well as the current research on traditional Chinese medicine in the regulation of BAs, in order to further understand the mechanism of action of BAs in affecting intestinal flora and liver function, expand the knowledge of its regulatory mechanism, explore the mechanism of action of traditional Chinese medicine and related pathways in regulating BAs, and provide new ideas for the prevention and treatment of liver-related systemic diseases by regulating BAs.

OBJECTIVE: To summarize and analyze the diagnostic ideas of new occupational lung tumors in Guangdong Province.METHODS: According to the Law of the People′s Republic of China on the Prevention and Control of Occupational Disease and the GBZ 94-2002 Diagnostic Criteria of Occupational Cancer, the key diagnostic points of 6 new occupational lung tumors diagnosed in Guangdong Province from 2010 to 2011 were analyzed. RESULTS: There were 9 cases of 6 new kinds of new occupational tumors were diagnosed in Guangdong Province in 2010-2011. The cases included 3 occupational lung cancer of coke oven workers, 2 occupational lung cancer caused by asbestos, 1 occupational mesothelioma caused by asbestos, 1 occupational lung cancer caused by arsenate, 1 occupational lung cancer caused by chromate salt, and 1 occupational lung cancer caused by asphalt. During the process, the diagnosis was based on the principles of the comprehensive analysis and the attribution diagnosis, combined with occupational history, occupational disease hazard exposure history, clinical data and auxiliary examination results. If the patients were diagnosed with a primary tumor, the patients′ exposure history to occupational carcinogens should be tracked, traced and confirmed, and the diagnosis should be confirmed by referring to the list of occupational carcinogens and literature reports of the International Labor Organization, and not limited to only the personnel in a particular industry. CONCLUSION: During the diagnostic process of occupational tumors, attention should be paid to confirm the exposure history of occupational carcinogen. The key is to determine the exposure of corresponding occupational carcinogen, the route and the time of exposure and the incubation period.
