Objective:To explore and analyze the effect of massive transfusion protocol (MTP) in early massive transfusion and prevention of coagulation disease for patients with multiple injuries.Methods:A retrospective analysis was made in 117 patients with multiple injuries admitted to Yiwu Central Hospital from March 2015 to May 2019.According to different blood transfusion schemes, they were divided into control group(53 cases) and observation group(64 cases). The patients in the control group received routine blood transfusion scheme, and the patients in the observation group received MTP blood transfusion scheme.The changes of blood routine and coagulation function, the amount of blood loss within 24h, the amount of allogeneic blood component input, the length of hospital stay and mortality were compared between the two groups.Results:The levels of Hb, HCT and PLT in the two groups after 24h of blood transfusion were significantly higher than admission[(112.73±12.73)g/L vs.(96.74±10.28)g/L, (115.28±19.27)g/L vs.(95.37±11.47)g/L, (39.72±5.21)% vs.(31.47±4.22)%, (39.10±4.97)% vs.(30.56±4.13)%, (220.93±54.28)×10 9/L vs.(142.83±36.47)×10 9/L, (216.87±64.03)×10 9/L vs.(148.96±40.22)×10 9/L, t=7.818, 6.464, 9.844, 9.621, 9.554, 6.538, all P<0.05], but there were no statistically significant differences between the two groups( t=0.681, 1.172, 0.864, 0.746, 0.740, 1.363, all P>0.05). After 24h of blood transfusion, the time of Pt and APTT in the observation group were significantly lower than admission[(13.21±2.93)s vs.(16.28±4.26)s, (46.28±3.97)s vs.(54.37±6.42)s, t=4.705, 8.574, all P<0.05], but there were no statistically significant changes in the control group[(15.84±3.62)s vs.(16.93±5.17)s, (54.02±6.39)s vs.(55.29±7.02)s, t=0.212, 0.332, all P>0.05]. The time of Pt and APTT in the observation group after 24h of blood transfusion were significantly lower than those in the control group ( t=4.344, 8.006, all P<0.05). There were no statistically significant differences in FIB levels between the two groups[(4.30±0.48)g/L vs.(4.36±0.56)g/L, (4.41±0.58)g/L vs.(4.51±0.63)g/L, t=0.651, 0.934, all P>0.05]. There were no statistically significant differences in 24h bleeding volume and fresh frozen plasma(RBC) input between the two groups[(2 684.92±703.47)mL vs.(2 725.86±810.32)mL, (17.28±3.74)U vs.(17.02±2.95)U, t=0.293, 0.411, all P>0.05]. The input amount of red blood cell suspension(PF) and the ratio of PF: RBC in the observation group were significantly higher than those in the control group[(9.28±3.27)U vs.(6.29±3.18)U, (0.55±0.12) vs.(0.39±0.10), t=4.985, 7.733, all P<0.05]. The observation group had significantly lower SOFA scores and ICU stays compared with the control group[(5.93±1.64)points vs.(7.28±2.10)points, (7.21±1.85)d vs.(9.10±2.37)d, t=3.814, 4.732, all P<0.05], and the mortality rate in the observation group was significantly lower than that in the control group[6.25%(4/64) vs.20.75%(11/53), χ 2=5.457, P<0.05]. Conclusion:The standardized rescue strategy of a large number of blood transfusion treatment schemes and the early proportion of components of blood products (erythrocyte suspension, fresh frozen plasma, platelets) can significantly improve the coagulation function of patients with multiple injuries, reduce the incidence of coagulopathy and help reduce the fatality rate of major bleeding, which is worthy of clinical promotion.

Objective:Metabolic syndrome (MS) patients and determine factors related to platelet hyperactivation.Methods:A total of 999 participants (822 males and 177 females) were enrolled. Participants were divided into two groups according to the metabolic index: MS group (501) and normal control (NC) group (498). Platelet function was tested with PFA100 (Siemens USA, Deerfield, Illinois) which measures the time it takes for blood to occlude an aperture (closure time, CT) following stimulation with collagen and adenosine diphosphate. Statistical analyses were performed using the SPSS statistical software package, version 22.0 (IBM Corporation, Armonk, NY, USA).Results:MS group had significantly shorter CT values compared with NC group (106.6±27.8s) vs (113.7±27.9s). Higher BMI, WC, BP, TC, TG, LDL-C, UA, and PRL were correlated with shorter CT values (all P<0.05). Conclusion:Our results indicated platelet hyperactivation exists in MS which was related to obesity and elevated blood pressure, blood lipids, uric acid, and PLR.

BACKGROUND:Electrical stimulation is a physical method that can be used to induce various cellular activities such as cell proliferation,differentiation,and apoptosis.The induction of osteogenic differentiation of stem cells will be beneficial in the field of bone regeneration. OBJECTIVE:To observe whether micro-current field can promote the proliferation and osteogenic differentiation of human umbilical cord mesenchymal stem cells. METHODS:The fresh human umbilical cord tissue was cut to obtain umbilical cord mesenchymal stem cells,which were inoculated into a 6-well plate after cell culture and passage to the third generation.After 24 hours,the cells were cultured under a stimulation of 0,50,and 100 mV/mm micro-electric field,at a frequency of 1 hour per day for 3 continuous days.The growth and morphological changes of human umbilical cord mesenchymal stem cells were observed by a microscope.The cell proliferation was detected by CCK-8 assay and EdU staining.Alizarin red staining was used to detect the osteogenic differentiation ability of cells.Western blot assay was used to determine the expression of ERK signal pathway proteins. RESULTS AND CONCLUSION:(1)The optical density value and the number of proliferating cells in 50 and 100 mV/mm groups were significantly higher than those of the unstimulated group(P<0.05).(2)Human umbilical cord mesenchymal stem cells could be induced to differentiate into osteocytes before and after micro-electric field stimulation,but the differentiation rate of 50 and 100 mV/mm groups was faster than that of unstimulated groups.(3)The protein expression of p-ERK1/2 in the 50 and 100 mV/mm groups was higher than that in the unstimulated group,and significant difference was detected between the 100 mV/mm group and the unstimulated group(P<0.05).(4)Micro-electric field can promote the proliferation of human umbilical cord mesenchymal stem cells,and the mechanism may be achieved by promoting the phosphorylation of ERK.

Objective:To explore the method and curative effect evaluation of repairing and rebuilding the long segmental bone defect after resection of long bone malignant tumors in adolescents.Methods:Reviewed our experience in 10 patients. Among them, 4 were male and 6 were female. The age was 10.2 years old (range, 6-16 years old). Including 7 cases of osteosarcoma, 3 cases of Ewing's sarcoma; 2 cases of humerus tumors, 7 cases of femoral tumors, and 1 case of tibial tumors-who presented between April 2015 and October 2019, in which the proportion of bone defect account for 71.4%-89.3% of the total length of diseased bone after tumor resection, with an average value of 80.9%. Considering the epiphyseal growth of young people, on the premise of ensuring enlarged tumor resection, we use traditional fibula autograft and prosthesis combined with steel plate, 3D printing design to retain the super-prosthesis of the epiphysis, and 3D printing bone trabecular was processed for the sake of making it grow successfully into the binding part of prosthesis and bone as we expect, simultaneously, the design of the short-force arm retaining the bilateral epiphysis can assit the steel plate and interlocking screws to enhance the stability.Results:The operation was completed successfully, and there were no complications such as nerve and blood vessel injury during the operation. After follow-up of 4-8 months, with an average follow-up of 22.9 months. One patient's review of X-ray film after 2 years of the operation showed that the transplanted fibula had a sign of bone resorption, and the internal fixation was in it's original position without obvious abnormalities. Two cases' auxiliary steel plates had fractured within one and a half to two years after surgery. With replacing the fractured steel plates, the internal fixation was good until now. According to the evaluation standards of the International Society of Limb Salvation: 2 cases of humerus osteosarcoma were respectively scored 23 points, 26 points, an average of 24.5 points; 4 cases of femoral osteosarcoma and 3 cases of femoral Ewing's sarcoma respectively scored 26 points and 25 points, 19 points, 30 points, 27 points, 24 points, 28 points (average, 25.6 points); 1 case of tibial osteosarcoma scored 26 points; all obtained relative satisfying treatment results.Conclusion:The combination of 3D printing and traditional machining techniques to produce an individualized long segmental prosthesis that preserves the epiphysis which applicated in the limb salvage treatment of bone malignant tumors can achieve excellent therapeutic effect.
