Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

【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.

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.

【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. The experimental group (n=22) received general rehabilitation training (such as exercises, occupational therapy, acupuncture and transcranial magnetic stimulation) plus AOBT (200 mL venous phlebotomy at the median elbow), once every 2 to 3 days and 12 occasions as a course of treatment; the control group solely recieved general rehabilitation training. The consciousness (GCS score) and ability of daily living (Barthel index score) score of the two groups before and after treatment were statistically compared, and Ueda motor function grade, Brunnstrom stage and muscle tone grade were observed and evaluated. 【Results】 After the treatment, the experimental group and the control were compared as follows: 1) the GCS score and Barthel score was 14.82±0.39 vs 12.41±2.52, 61.14±12.24 vs 52.05±11.72(P<0.05); 2) The recovery rate of motor function was 95.45% (21/22) vs 63.64% (14/22) (P<0.05); 3) The total recovery rate of muscle tone was 90.91% (20/22) vs 63.64% (14/22) (P<0.05). 【Conclusion】 AOBT, with somewhat high safety and effectiveness, can improve the state of consciousness, motor function and muscle tone in convalescent patients with stroke.

Autologous ozonized blood transfusion (AOBT) is a therapeutic method that mixes blood with medical ozone in vitro and then reinfuses it into the body. It has been widely used in the auxiliary treatment of ischemia, hypoxia, autoimmune diseases and cancer. The mechanism of ozone therapy is still unclear, and no unified standard for the concentration, frequency and course of AOBT treatment has been established. This article aims to review the mechanism and clinical application of AOBT.

Objective:To compare the clinical effects of different approaches of unilateral thyroid lobectomy in the treatment of papillary thyroid microcarcinoma (PTMC) .Methods:From Jun. 2019 to Jun. 2022, 70 patients with PTMC from Thyroid and Breast Surgery Department of Taihe Hospital and Dongfeng General Hospital were selected for prospective study. They were divided into transoral group with 35 cases according to random number table method. Trans-oral endoscopic thyroidectomy (TOET) was adopted in 11 males and 24 females, aging (40.71±5.09) years old, ranging from 23 to 60 years old; 35 cases in the trans-axillary group, using trans-axillary approach Endoscopic thyroidectomy by areola approach (ETAA) including 13 males and 22 females, aging (40.25±5.06) years old, ranging from 24 to 59 years old. Perioperative indicators, inflammatory factors, and stress indicators were recorded in the two groups. The level and complications were followed up for 3 months to evaluate the aesthetics of surgical incisions. The comparison of measurement data between groups was performed by independent t test, and the comparison of count data was conducted by χ2 test. Results:The number of lymph nodes dissected and intraoperative blood loss in the oral cavity group were significantly better than those in the axillary group [ (8.71±0.93) vs (6.85±0.82), (23.05±3.51) ml vs (26.14±3.96) ml] ( t=8.88, 3.46, P<0.05) ; The first day after operation, serum norepinephrine (NE) and cortisol (Cor) in the oral cavity group were significantly lower than those in the axillary group [ (275.31±30.41) ng/L vs (300.22±33.25) ng/L, (180.25±19.75) nmol/L vs (205.36±22.41) nmol/L] ( t=3.27, 4.97, P<0.05) ; The first day after operation, the levels of serum C-reactive protein (CRP) and interleukin-6 (IL-6) in the oral cavity group were significantly lower than those in the axillary group [ (7.05±0.86) mg/L vs (8.74±1.02) mg/L, (4.33±0.62) pg/L vs (6.45±0.81) pg/L] ( t=7.49, 12.30, P<0.05) ; there was no significant difference in the incidence of complications between the groups ( P>0.05) ; Three months postoperatively, the aesthetics of the incision in the oral cavity group (94.29%) was significantly higher than that in the axillary group (77.14%) ( χ2=4.20, P<0.05) . Conclusion:When unilateral thyroid lobectomy is performed for papillary thyroid microcarcinoma, the transoral vestibular approach is less invasive than the transaxillary approach, and the effect of lymph node dissection is better, which is beneficial to reduce the surgical stress response of patients, and the aesthetics of the surgical incision are higher.

Granulocyte is granular leukocytes in blood, which play an important role in anti-infection treatment and cancer-killing activity. In clinical, allogeneic granulocyte transfusion can be applied for anti-infection treatment when the patients are seriously infected but the antibiotic treatment is ineffective, especially the WBC counts are extremely low. Recently, some progress has been made in the researches about treating cancer with granulocyte infusion. It is possible to use allogeneic granulocyte infusion with high killing activity to treat the certain types of cancers.

【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.
