Objective: To investigate the causes and treatment of congenital absence of clotting factor VII. Method: The clinical data of one infant with the disease of congenital absence of clotting factor VII in our department were retrospectively analyzed. Result: The infant was transferred to neonatal ICU because of the skin bleeding for no apparent reason. The determination of coagulation factor VII was C 0.5%, revealing the coagulation factor VII deficiency. The coagulation factor VII C of the infant's parents and sister was respectively 28.5%, 31.0% and 25.2%, indicating the relationship with genetic factors. After repeated infusion of fresh frozen plasma and prothrombin complex, the infant recovered and was discharged from hospital. Conclusion: In clinical work, coagulant function abnormality of neonatal repeatedly, we should check the clotting factor as soon as possible in order to avoid missed diagnosis, misdiagnosis and delay treatment.

Utilizing the Liapunov functional method and combining the inequality of matrices technique to analyze the existence of a unique equilibrium point and the global asymptotic stability for delayed cellular neural networks (DCNNs), a new sufficient criterion ensuring the global stability of DCNNs is obtained. Our criteria provide some parameters to appropriately compensate for the tradeoff between the matrix definite condition on feedback matrix and delayed feedback matrix. The criteria can easily be used to design and verify globally stable networks. Furthermore, the condition presented here is independent of the delay parameter and is less restrictive than that given in the references.
