Acute respiratory distress syndrome (ARDS) is a common diseases in critical ill patients, which is an acute-onset hypoxic condition with radiographic bilateral lung infiltration. And it can be divided into two phases in pathophysiology: an acute exudative phase combining diffuse alveolar damage and lung edema followed by a later fibro proliferative phase. The early prediction and risk assessment of patients with ARDS is still very poor in the clinical. In recent years, researchers gradually focus their research on exploration of biomarkers of ARDS. The article mainly aims to sum up the development of biomarkers exploration.

OBJECTIVE:
To explore the genetic basis for a Chinese pedigree affected with inherited afibrinogenemia.
METHODS:
For the proband and his family members, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), Fibrin(ogen) degradation products (FDPs), D-dimer (D-D), plasminogen activity (PLG:A) and the TT mixed experiment with protamine sulfate were determined with a STAGO-R automatic coagulation analyzer. The activity and antigen of fibrinogen (Fg) in plasma were measured with the Clauss method and immunonephelometry method, respectively. All exons and flanking regions of the fibrinogen genes (FGA, FGB and FGG) were amplified by PCR and directly sequenced. Human Splicing Finder software was used to predict and score the change of splicing site caused by the mutation.
RESULTS:
The proband showed normal FDPs and D-D but significantly prolonged TT, PT and APTT. The activity and antigen of fibrinogen in plasma were significantly decreased (<0.1 g/L). His young sister and parents showed slightly prolonged TT (18.20-18.50 s) and decreased fibrinogen activity (1.27-1.54 g/L) and fibrinogen antigenic content (1.34-1.56 g/L). Genetic testing revealed that the proband has carried homozygous IVS7-12A>G (g.4147A>G) mutations of the FGG gene, for which his parents and young sister were heterozygous. As predicted by Human Splicing Finder and Mutation Taster software, the variant may generate a new splicing site which can extend the sequence of exon 7 by 11 bp, with alteration of the coding sequence. PROVEAN suggested the variant to be deleterious.
CONCLUSION
The afibrinogenemia of the proband may be attributed to the FGG IVS7-12A>G variant, which was unreported previously.

Objective:To analyze the phenotype and genotype of two Chinese family with inherited dysfibrinogenemia and the molecular pathogenic mechanism.Methods:In the probands and their family members, coagulation routine, fibrinogen activity(Fg∶A) and fibrinogen antigen(Fg∶Ag) were detected . To find the mutation and exclude single nucleotide polymorphisms, all the exons and exons-intron boundaries of fibrinogen genes ( FGA, FGB and FGG) were amplified by Ploymerase Chain Reaction (PCR), then sequenced. Bioinformatics prediction softwares were used to predict and score the change of function caused by the variant. PyMol were used to analyze the structure of protein caused by the variant. Clustal X software was used to analyze the conservation of the mutant amino acids. Results:The thrombin time(TT) of the two was slightly prolonged and could not be corrected by protamine sulfate, and the fibrinogen activity was significantly reduced (1.25 g/L and 1.17 g/L), but the fibrinogen antigen content was normal, respectively (3.50 g /L and 3.81 g/L). Genetic analysis showed that both probands were heterozygous missense variants( FGB exon 7 c. 1115 T>A (p.Val372Glu)), both of which originated from the paternal line. The prediction results of the four bioinformatics softwares indicate that this variant could be disease causing. Clustal X software showed that Val372 is highly conserved among homologous species. Based on the guidelines of the American College of Medical Genetics and Genomics, c. 1115 T>A was predicted to be likely pathgenic(PM2+ PP1+ PP2+ PP3+ PP4). PyMol shouwed p. Val372Glu variant changes the secondary structure and three-dimensional structure of fibrinogen protein were changed caused by p. Val372Glu variant. Conclusion:Inherited dysfibrinogenemia of the probands maybe caused by variant of FGB c. 1115 T>A(p.Val372Glu), and the variant was firstly reported.
