Objective To investigate the effect of ambroxol pretreatment on the inflammatory response and lipid peroxidation during one-lung ventilation (OLV) .Methods Forty-five ASA I or II patients aged 37-64 yr weighing 53-65 kg undergoing thoracotomy under general anesthesia were randomly divided into 3 groups ( n = 15 each): group A two-lung ventilation (TLV); group B OLV and group C ambroxol 1 mg/kg + OLV. Anesthesia was induced with midazolam, fentanyl, propofol and atracurium and maintained with propofol infusion and intermittent iv boluses of fentanyl and atracurium. The patients were mechanically ventilated (VT8-10 ml/kg, RR 12 bpm during TLV, VT 6-7 ml/kg, RR 16 bpm during OLV, I: E 1:2, FiO2 100% ). In group C ambroxol 1 mg/kg in normal saline ( NS) 100 ml was infused at 25 min before OLV (infusion rate 4 ml/min) , while in group A and B equal volume of NS was infused instead of ambroxol. Blood samples were obtained from radial artery before induction of anesthesia and OLV (T0.1 ) and at 0.5, 1, 2 h of OLV (T2-4 ) and 1, 2 h of TLV (T5,6 ) and at 24 h after operation (T7) in group B and C for determination of serum SOD activity and TNF-α, IL-6 and IL-8 concentrations and WBC and neutrophil granulocyte counts. The same indexes were detected in group A at the corresponding time points.Results Serum SOD activity was significantly lower and serum TNF-α, IL-6 and IL-8 concentrations and WBC and neutrophil granulocyte counts were significantly higher in group B than in group A. Serum SOD activity was significantly higher and serum TNF-a, IL-6 and IL-8 concentrations and WBC and neutrophil granulocyte counts were significantly lower in group C than in group B. Conclusion Pretreatment with ambroxol 1 mg/kg can inhibit inflammatory response and lipid peroxidation during OLV.

Objective To investigate the effects of autologous blood transfusion and allogeneic blood transfusion on postoperative complications and outcome of patients underwent craniotomy with traumatic brain injury.Methods All transfusional cases underwent emergency craniotomy with trau-matic brain injury from January,2012 to June,201 6,1 61 males and 38 females,ASA physical statusⅠ-Ⅳ,were respectively analyzed and divided into autologous blood group (n = 108)and allogeneic blood group (n =91)based on whether or not using cell salvage.The restrictive transfusion strategy was applied in the two groups and the red blood cells were infused to maintain the hemoglobin concen-tration at 70-100 g/L.The incidence of postoperative complications and adverse transfusion reaction were analyzed and the clinical outcome was judged by Glasgow outcome score (GOS).Results The incidence of postoperative complications (33% vs.56%,P <0.01 )and adverse transfusion reaction (5% vs.14%,P <0.05)of the autologous blood group were lower than that in the allogeneic blood group,and the clinical outcome was better (P <0.01).Logistic regression analysis showed that allo-genetic transfusion (OR =1.953,95%CI 1.381-2.529)was an independent risk factor of postopera-tive complications.Conclusion The use of autologous blood transfusion in patients with traumatic brain injury can reduce the incidence of postoperative complications and the risk of blood transfusion and improve clinical outcome.

【Objective】 To establish an information management platform for provincial rare blood group bank to achieve the interconnection and sharing of data such as rare blood group types, donor information and blood inventory, so as to enhance the supply security of rare blood group blood. 【Methods】 The information barriers of rare blood group management in each business link and among blood stations in Zhejiang province were analyzed using fishbone diagram. Data modeling technology was introduced based on the unified blood collection and supply business system and blood cloud platform of Zhejiang, the database view of rare blood group donors and rare blood group was constructed through demand analysis and model design, and a unified query platform was developed to achieve the sharing of rare blood group information. 【Results】 The system integrated, retrievaled and displayed rare blood type information, achieving the interconnection of information among various business links and blood stations within blood banks. Up to now, in addition to RhD negative blood group, there were 8 types of rare red blood cells in the bank, covering 7 blood group systems, 289 rare blood group donors and 216 units of frozen red blood cells of rare blood group. 【Conclusion】 The information system based on data modeling can improve the overall efficiency and collaboration of the system, and reduce the workload of system development and operation. It can provide reference for standardized data management and application, and also provide a model for establishing and improving of a national rare blood group information network.
