Objective To explore the acquired deficiencies of vitamin K-dependent coagulation factors in etiology, clinical characteristics and treatment. Methods Retrospective analysis was performed on the data of etiology, clinical manifestations of 45 patients with acquired deficiencies of vitamin K-dependent coagulation factor. All patients were treated with Vitamin K1 10 -40 mg/d, i. v. , for three months. Some patients with severe blooding were additionally treated with fresh freezing plasma or prothromibin complex. Prothrombin time(PT) and activated partial thromboplastic time(APTT) were measured using Stago automatic blood coagulation analyzer before and after treatment. Ⅱ , Ⅶ, Ⅸ and Ⅹ were measured in some patients. Results Among the 45 cases, no certain cause was found in 19 cases (42.2%), anticoagulant rodenticides poison was a common cause ( 11 cases,42.3% ). The main presentations was hemorrhage, the most common bleeding sites were mucosa (77.8%) (35/45)and hematuria (46.7%) ( 21/45 ). After vitamin K1 treatment, PT and APTT had shortened remarkably from ( 110.35 ± 35.36 ) s,(98.91 ±48.98)s to (13.48 ±2. 17)s,(33.25 ±6.95)s,respectively(t=19.10 and 6.19,Ps ＜0.01)and the activities of factor Ⅱ、Ⅶ、Ⅸ、Ⅹ had rapidly increased from ( 17.48 ± 10.93 ) %, ( 10.23 ± 5.68 )%, ( 11.98 ±4.69)%,(12.93±7.48)% to (70. 12 ±21.31)%,(92.76 ±29. 15)%,(88.64 ±40. 21)%,(63.97 ±20.11)%(t=12.13,14.43,13.27and9. 74,respectively,Ps＜0. 01).Conclusions The histories of patients with acquired deficiencies of vitamin K-dependent coagulation factors are usually hiding, therefore it is easily misdiagnosed. It is worth of detecting PT and APTT in diagnosis and monitoring. Using vitamin K1 10 -40 mg/d is effective and safety.

A suitable ultra-high performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) method was developed for the determination of 11 mycotoxins with isotope internal standard in malt. The mycotoxins in malt were extracted and purified by one-step ultrasonic extraction procedure using acetonitrile/water/acetic acid (80 : 19 : 1), and then detected and confirmed by UPLC-MS/MS, and quantified by isotope labeled AFB1 ([13C17]-AFB1) and ZEN ([13C18]-ZEN) internal standards. Rapid separation of the 11 mycotoxins was successfully achieved on a Phenomenex Kinetex C18 column (100 mm x 2.1 mm, 2.6 μm) with gradient elution using the mobile phase of methanol containing 0.1% formic acid and 2 mmol x L(-1) ammonium acetate in water. Simultaneous acquisition was performed in multiple reaction monitoring (MRM) mode with electrospray ionization (ESI) source operated in both positive and negative ionization modes. The established method provided a good linearity for the 11 mycotoxins within their respective linear ranges with correlation coefficients all higher than 0.999 1. The average recoveries ranged from 75.0% to 117.0% with relative standard deviations (RSDs) below 5.1%. The limits of detection (LODs) and quantitation (LOQs) ranged from 0.05 to 30 μg x kg(-1) and 0.15 to 87.5 μg x kg(-1), respectively, which were below the maximum residue levels (MRLs) set by the European Union. Twenty malt samples were analyzed and nine samples were detected with mycotoxins, which were confirmed according to the same fragment ions found in positive samples and the standards at the same retention time. This study has demonstrated that the one-step extraction procedure of mycotoxins from complex matrices coupled to UPLC-MS/MS method is simple, quick, accurate and sensitive for quantitative and qualitative analysis of multiple mycotoxins in malt.
