【Objective】 To explore the perioperative blood management in patients with pancreatic pseudocyst combiend with coagulation factor Ⅴ(FⅤ) deficiency. 【Methods】 Preoperative: In order to determine the effect of cryoprecipitated antihemophilic factor and fresh frozen plasma (FFP) on the elevation level of factor Ⅴ, we alternately infused cryoprecipitate and FFP in the resting state. TEG, coagulation function and coagulation factor activity were monitored before and 1 h, 24 h and 48 h after infusion, and intraoperative and postoperative blood transfusion strategies were formulated. FFP 600 mL and cryoprecipitate 10 U were supplemented preoperatively. Intraoperative: The operation procedure was performed for 7 hours with an infusion of 600 mL FFP without significant bleeding. Postoperative: FFP was infused. 【Results】 Preoperative: The coagulation factor Ⅴ activity on pre-operation was 1.9% and 1.8%. After alternating infusion cryoprecipitate 10 U and FFP 1 200 mL, the FⅤactivity increased to 5.1% and 6.0%, respectively. There was no significant difference in TEG parameters, PT and ATPP results were decreased to varying degrees. Intraoperative: The operation was successful without obvious bleeding. Postoperative: FFP 500 mL was infused 2 h after operation, and FFP 250-500 mL was injected daily from 1 to 7 days after surgery. No significant bleeding was observed in the wound, the results of TEG, PT, APTT and hemoglobin (Hb) did not change significantly compared with those before surgery. The patient was discharged successfully 12 days after surgery. The genetic test results showed that he had inherited coagulation factor Ⅴ deficiency, which was a compound heterozygous variation. 【Conclusion】 Perioperative blood management in patients with FⅤ deficiency combined with surgical disease, requiring pre-transfusion evaluation and post-transfusion evaluation in combination with laboratory investigations and clinical manifestations, cryoprecipitate and fresh frozen plasma can be effective in supplementing coagulation factors. The TEG seems to be better than the Seven items of coagulation function in judging the clotting status of patients with FⅤ deficiency.

【Objective】 To explore the effect of allogeneic platelet gel on hemostasis and repair of vascular anastomoses and wounds in patients with giant aortic aneurysms during surgery. 【Methods】 One adult dose of allogeneic platelets, applied as platelet rich plasma (PRP), was prepared as platelet gel (PG) (about 220 mL) for spraying or smearing at the vascular anastomosis and thoracic wound during the surgery of giant aortic aneurysms. 【Results】 The gel formation was presented about 30 seconds after spraying or smearing with PG on the anastomotic and wound surface. The hemostatic effect is good, with less postoperative drainage fluid from pericardium and mediastinum than usual, and the ICU stay was 4 days. 【Conclusion】 Allogeneic platelets as a source of PRP to prepare PG may be applied to obtain the clotting and healing during surgical operation.

【Objective】 To investigate the clinical efficacy and safety of centrifugal plasma separation combined with plasma adsorption in the treatment of hypertriglyceridemia. 【Methods】 The data of 42 patients with hypertriglyceridemia from February 2019 to October 2020 were retrospectively collected and analyzed. The patients were treated with plasma component exchange by centrifugal plasma separation combined with plasma adsorption (PA) lipid-lowering therapy. The plasma was separated by an automatic blood cell separator, and was then adsorbed by membrane plasma component absorber. Conditions for plasma component exchange were sodium citrate as anticoagulant, the whole blood flow rate at (30~80) mL/min, the plasma circulation volume 2 500 mL, the treatment time 2 h, and the discarded plasma 200 mL. The treatment was performed once every two weeks, twice in total, and the efficacy was evaluated 6 weeks later. The changes of serum total protein (TP), blood lipid indexes and hemorheology indexes before and after treatment were observed, and the adverse reactions during treatment were recorded. 【Results】 The effective rate of 42 patients after treatment was 95.24%. The values of TP, TC, TG and LDL-C decreased significantly (82.53±6.37 vs 74.26±5.91, 7.46±1.83 vs 3.88±1.06, 5.91±2.16 vs 2.20±1.13, 4.23±1.02 vs 3.17±0.85) while HDL-C increased significantly(0.92±0.15 vs 1.23±0.26) after the treatment (P<0.05). After the treatment, the levels of whole blood high-cut viscosity, whole blood low-cut viscosity, plasma viscosity, hematocrit and fibrinogen decreased significantly (7.53±1.21 vs 5.16±0.88, 18.27±3.15 vs 12.04±2.32, 2.46±0.37 vs 1.68±0.29, 52.24±5.31 vs 32.53±4.42, 4.28±0.76 vs 3.14±0.45)(P<0.05). The incidence of adverse reactions was 14.3%, and no serious adverse reactions were observed. 【Conclusion】 The centrifugal plasma separation combined with plasma adsorption in the treatment of hypertriglyceridemia is safe and effective.

【Objective】 To investigate the efficacy of autologous ozoneized blood transfusion(AOBT) in improving consciousness and motor function in convalescent stroke patients. 【Methods】 A total of 44 patients who were diagnosed as convalescent cerebral apoplexy and received treatment in Rehabilitation Department of our hospital from August 2016 to September 2021 were randomly divided into the experimental group and control group by blind method.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.
