Efficacy of apolipoprotein 2-Jifusheng in the treatment of osteomyelitis in rabbits / 中国骨伤

OBJECTIVE@#To evaluate the effect of one-stage treatment of bone morphogenetic protein 2 combined with Jifusheng in the experimental model of osteomyelitis in rabbits.@*METHODS@#The model of chronic osteomyelitis of tibia was established in 30 3-month-old male New Zealand white rabbits with a body weight of (2.0±0.5) kg, and the model was verified 4 weeks after operation. Thirty rabbits with osteomyelitis were randomly divided into 3 groups with 10 rabbits in each group (@*RESULTS@#At 4 weeks after operation, 30 rabbits with osteomyelitis were successfully validated. The results of serological examination showed that the hypersensitive C-reactive protein (CRP) and white blood cell count(WBC)in the model group were significantly higher than those in the blank group at 2 and 4 weeks after operation. Eight weeks after treatment, the detection of blood indexes showed that the white blood cell count (WBC)and hypersensitive C reactive protein (CRP)in treatment group A and treatment group B were significantly lower than those in the model group (@*CONCLUSION@#The combined application of apolipoprotein 2-Jifusheng can promote bone repair and reduce the inflammation of the focus. it can treat rabbits with osteomyelitis in one stage, provide objective basis for the formulation of clinical treatment strategy of osteomyelitis and further promote clinical research.

Effect of plasma fibrinogen level-based defibrase therapy in patients with acute cerebral infarction / 南方医科大学学报

<p><b>OBJECTIVE</b>To evaluate the therapeutic effect of individualized defibrase therapy according to the level of plasma fibrinogen (FIB) in patients with acute cerebral infarction (ACI).</p><p><b>METHODS</b>Sixty patients with ACI (within 72 h after onset) were randomly divided into defibrase group (n=30) and control group (n=30). The patients in defibrase group received intravenous defibrase infusion at different first doses (15, 10, and 5 U) according to plasma FIB level (>4 g/L, 2-4 g/L, and 1.3-2 g/L) before treatment. Plasma FIB was measured every 12 h after the first dose of defibrase, and when plasma FIB was over 1.3 g/L, intravenous infusion of 5 U defibrase was given to maintain plasma FIB within the range of 0.70-1.13 g/L over a period of 7 days. The plasma prothrombin time (PT), activated partial thromboplastin time (APTT) and FIB before and after the 7-day treatment were measured, and the scores of Chinese stroke scale (CSS) after 14 days of treatment and Activity of Daily Living (ADL) after 3 months were recorded.</p><p><b>RESULTS</b>After 7 days of treatment, plasma PT and APTT were significantly prolonged lengthened and plasma FIB was lowered in defibrase group. The scores of CSS improved in defibrase group after 14 days of treatment, showing significant difference from those of the control group. The clinical effective rate was 80% in defibrase group, significantly higher than that in the control group (50%). The scores of ADL after 3 months were similar between the 2 groups, but the percentage of independent living and mild dependency was significantly higher in defibrase group (93.3% vs 70.0%). No intracerebral and extracerebral hemorrhage occurred in defibrase group the during treatment, no did death occur after 3 months of treatment.</p><p><b>CONCLUSION</b>Defibrase therapy based on plasma FIB level can rapidly and effectively lower plasma FIB, reduce neurological impairment and improve the quality of life in patients with ACI.</p>
