Screening for the etiology of non-cirrhotic splanchnic vein thrombosis should be taken seriously in clinical practice / 临床肝胆病杂志

Non-cirrhotic splanchnic vein thrombosis （NC-SVT） mainly includes portal vein thrombosis， superior mesenteric vein thrombosis， splenic vein thrombosis， and hepatic vein thrombosis （Budd-Chiari syndrome）， and its prevalence rate is increasing with the increase in the incidence rates of related underlying diseases. Due to the harm of NC-SVT， there have been significant improvements in the awareness and ability for diagnosis among clinicians. However， anticoagulation and intervention therapies for thrombosis are often taken seriously in treatment， while the screening for risk factors or underlying diseases leading to SVT is ignored， which may affect the treatment outcome of thrombus in some patients and delay the diagnosis and treatment of the underlying disease. This article mainly introduces the acquired， hereditary， systemic， and local underlying diseases associated with the development of NC-SVT.

Progress in subclinical research of kidney xenotransplantation / 器官移植

Xenotransplantation is an efficient pathway to solve the problem of transplant organ source deficiency in clinical settings. With the increasing progress of gene editing technique and immune suppression regimen, important development has been achieved on researches regarding pig to non-human primate kidney xenotransplantation, which provides a good condition for the introduction of the technique in the clinical application. In view of the substantial difference between human and non-human primate, and to meet the needs of current ethic requirements, it is necessary to perform subclinical studies for pig to human kidney xenotransplantation. In recent years, such subclinical studies with regard to the genetically modified pig to brain death recipient kidney xenotransplantation had been performed, indicating that kidney xenotransplantation gradually began to transit to the clinical development stage. However, donor/recipient selection and immune suppression regimen has not reached a consensus yet, and has to be clarified in subclinical studies. In this article, the current status and confronted problems of donor/recipient selection, immune suppression regimen and post transplantation management in the subclinical studies of kidney xenotransplantation were reviewed, aiming to promote the clinical transformation of kidney xenotransplantation to the clinical application.

Serum thyroid function, hs-CRP expression, and coagulation function in syphilis patients / 公共卫生与预防医学

Objective To investigate the serum levels of thyroid function and hs-CRP expression in patients with syphilis and their relationship with coagulation function. Methods A total of 80 syphilis patients admitted to Bazhong Central Hospital from January 2020 to January 2022 were selected as the study subjects and set as the observation group. In addition, 80 healthy individuals were selected as the control group, and 80 psoriasis patients were selected as the disease control group. Thyroid function, hs-CRP and coagulation function among different groups were compared. The correlation between thyroid function, hs-CRP, and coagulation function in patients with syphilis was analyzed, and the effectiveness of these parameters in predicting syphilis was analyzed. Results The values of FT3, FT4, TSH and hs-CRP in the observation group were higher than those in the control group and the disease control group (P<0.05). The abnormal rates of thyroid function and hs-CRP level in the observation group were higher than those in the control group and the disease control group (P<0.05). PT, APTT, and TT of the observation group were higher than those of the control group and the disease control group (P<0.05). The abnormal rate of coagulation function in the observation group was higher than that in the control group and the disease control group (P<0.05). The levels of FT3, FT4, TSH, hs-CRP, PT, APTT, and TT in the first stage were lower than those in the second and third stages, while these parameters in the secondary stage were lower than those in the third stage (P<0.05). The severity of syphilis was positively correlated with FT3, FT4, hs-CRP, APTT, and TT (P<0.05). Among these indicators, TT was more effective in the diagnosis of syphilis. Conclusion Syphilis patients have hyperthyroidism, accompanied by coagulation dysfunction and abnormal increase in hs-CRP, which are all related to the condition of syphilis patients. The combined prediction of syphilis patients has high effectiveness.

Prothrombin time, APTT, INR and D-dimer means had significant differences versus disease categories.

Re-understanding of the mechanism of coagulation disorder in liver cirrhosis / 临床肝胆病杂志

The liver plays an important regulatory role in maintaining the dynamic balance of coagulation and anticoagulation in the body. Such dynamic balance is fragile in patients with liver cirrhosis， and the risk of bleeding can be increased due to reductions in coagulation factors and platelet count and excessive fibrinolysis； meanwhile， thrombus can be formed due to the increases in von Willebrand factor and coagulation factor Ⅷ， the reductions in anticoagulant protein C and anticoagulant protein S， the increase in thrombin-generating potential， and alterations in antifibrinolytic components. This article reviews the mechanisms of coagulation disorder in liver cirrhosis， so as to help clinicians with the prevention and treatment of bleeding or thrombotic disorders in patients with liver cirrhosis.

Present situation and progress of xenotransplantation at home and abroad / 器官移植

Organ shortage has become one of the major challenges hindering the development of organ transplantation. Xenotransplantation is one of the most valuable methods to resolve global organ shortage. In recent years, the development of genetic engineering technique and research and development of new immunosuppressant have provided novel theoretical basis for xenotransplantation. International scholars have successively carried out researches on xenotransplantation in genetically modified pigs to non-human primates or brain death recipients, making certain substantial progresses. However, most of the researches are still in the preclinical stage, far from clinical application. Therefore, according to the latest preclinical experimental research progress at home and abroad, the history of xenotransplantation, the development of gene modification technology, xenotransplantation rejection and immunosuppression regimens were reviewed, aiming to provide reference for subsequent research of xenotransplantation, promote clinical application of xenotransplantation and bring benefits to more patients with end-stage diseases.

Influência do tratamento fisioterapêutico na independência funcional de pessoas com hemofilia submetidas à sinovectomia radioativa / Influence of physiotherapeutic treatment on the functional independence of people with hemophilia submitted to radioactive sinovectomy

A sinovectomia radioativa (SR) é considerada o tratamento de eleição no controle da sinovite crônica não responsiva ao tratamento conservador, sendo recomendado tratamento fisioterapêutico para a melhora da funcionalidade. Objetivo: Verificar a influência do tratamento fisioterapêutico na independência funcional e saúde articular de hemofílicos após tratamento com SR. Método: Trata-se de um estudo descritivo, retrospectivo, analítico e metodologia quali-quantitativa. Realizou-se avaliação fisioterapêutica, aplicação do HJHS para avaliação da saúde articular e Escore FISH para avaliação da independência funcional. Os participantes foram subdivididos em dois grupos de acordo com a realização ou não da fisioterapia após a SR. Resultados: Participaram do estudo 8 pessoas com hemofilia A, sexo masculino, média de idade de 19±5,3 anos. Foram 12 articulações submetidas a SR, dessas 41,67% cotovelos, 33,33% joelhos e 25% tornozelos. Na comparação dos grupos, não houve diferença estatística entre os eles nas variáveis: saúde articular e a Independência Funcional. Conclusão: O estudo é uma primeira tentativa de descrever o impacto da fisioterapia na independência funcional e saúde articular de hemofílicos submetidos à SR. Embora possua limitações, foi possível observar que o grupo que não realizou fisioterapia apresentava melhor saúde articular e melhor independência funcional previamente à SR em comparação ao grupo que realizou fisioterapia; porém, o grupo fisioterapia apresentava pior quadro global, com a funcionalidade impactada por outras articulações e não somente aquela tratada com SR, apresentando maior número de articulações alvo.

Radioactive synovectomy (RS) is considered the treatment of choice in the control of chronic synovitis resistant to conservative treatment, and physiotherapy is recommended to improve functionality after procedure. Objective: The aim was to verify the effects of physiotherapy on functional independence and joint health after RS. Method: This is a descriptive, retrospective, analytical study with qualitative/quantitative methodology. Physiotherapeutic evaluation, Hemophilia Joint Health Score (HJHS) application for joint outcome assessment and Functional Independence Score in Hemophilia (FISH) were used to measure the patient's functional ability. The participants were divided into two groups: one group underwent a physiotherapy program and one not treated with physiotherapy after RS. Results: The study included 8 people with hemophilia A, all male, their mean age was 19±5.3 years. Twelve joints were submitted to RS, in which 41.67% elbows, 33.33% knees and 25% ankles. In the comparison of the groups, there was no statistically significant difference between them in joint health and functional independence. Conclusion: The study is a first attempt to describe the impact of physiotherapy on functional independence and joint health of hemophilic patients submitted to SR. Although this study has limitations, it was possible to observe that the group not treated with physiotherapy had better joint health and better functional independence prior to SR compared to the group that underwent physiotherapy, but the group treated with physiotherapy had worse overall health and have their functionality impacted by joints other than those treated with RS, presenting a higher number of target joints.

Hemofilia adquirida tipo A

La hemofilia adquirida es un trastorno hemostático causado por la presencia de autoanticuerpos inhibidores contra el F VIII de la coagulación. Clínicamente se presenta como sangrado espontáneo, principalmente en piel y tejidos blandos, y a diferencia de la hemofilia congénita, la hemartrosis es rara. Se presenta el caso de un paciente de sexo masculino, de 60 años, previamente sano, que acude a consulta por cuadro de 8 días de evolución de aparición de hematomas a nivel de miembro superior e inferior. Durante su evolución presenta TTPA alargado y concentraciones bajas de F VIII.

Acquired hemophilia is a hemostatic disorder caused by the presence of inhibitory autoantibodies against coagulation F VIII. Clinically it presents as spontaneous bleeding, mainly in the skin and soft tissues, and unlike congenital hemophilia, hemarthrosis is rare. We present the case of a 60-year-old male patient, previously healthy, who came to the clinic due to an 8-day history of hematomas on the upper and lower limbs. During its evolution it presents prolonged APTT and low concentrations of F VIII.

Acute promyelocytic leukemia in childhood and adolescence: treatment results of a modified AIDA protocol at a Brazilian center

ABSTRACT Introduction: Acute promyelocytic leukemia currently presents an excellent chance of cure with protocols based on all-trans-retinoic acid (ATRA) and anthracycline or only differentiation agents. However, high early mortality rates continue to be reported Methods: Between 2000 and 2018, patients were enrolled and retrospectively analyzed by medical records. A modified AIDA protocol, with a 1-year shortening of the treatment duration, reduction in the number of drugs and a strategy to reduce early mortality by the postponement of the initiation of anthracyclines were employed. Overall and event-free survival rates and toxicity were analyzed Results: Thirty-two patients were enrolled, of whom 56% were female, with a median age of 12 years and 34% belonged to the high-risk group. Two patients had the hypogranular variant and three had another cytogenetic alteration, in addition to the t(15;17). The median start of the first anthracycline dose was 7 days. There were two early deaths (6%) due to central nervous system (CNS) bleeding. All patients achieved molecular remission after the consolidation phase. Two children relapsed and were rescued by arsenic trioxide and hematopoietic stem cell transplantation. The presence of disseminated intravascular coagulation (DIC) at diagnosis (p = 0.03) was the only factor with survival impact. The five-year event-free survival (EFS) was 84% and 5-year overall survival (OS) was 90% Conclusion: The survival results were comparable to those found in the AIDA protocol, with a low rate of early mortality in relation to the Brazilian reality.

Resumen: Introducción: Las pruebas de coagulación carecen de valor para determinar el riesgo de sangrado perioperatorio. Material y métodos: Se realizó un estudio observacional, descriptivo, y transversal en 2,114 pacientes en la consulta de Anestesiología del Hospital Universitario «Dr. Celestino Hernández Robau¼, los resultados se evaluaron mediante estadística descriptiva. Resultados: El tiempo de coagulación y sangrado se realizó en 100% de los casos y el conteo de plaquetas en 93.99%, mientras que el tiempo de protrombina y tiempo de tromboplastina parcial activado se efectuó en 66.27 y 55.62% de los casos respectivamente. De 8.834 exámenes realizados se encontraron 49 alterados en 0.55%. Los pacientes con exámenes alterados fueron 33 en 1.56%, los enfermos en riesgo de sangrado por exámenes de coagulación fueron 30 en 1.42% y los pacientes en riesgo sin antecedentes de sangrados detectados por exámenes de coagulación fueron tres en 0.14%. Se reportó sangrado perioperatorio en 16 pacientes en 0.76%, siete pacientes con interrogatorio positivo y exámenes normales y nueve pacientes con interrogatorio negativo y exámenes normales. Conclusiones: La historia clínica y el examen físico del paciente son las mejores herramientas para predecir el riesgo de sangrado quirúrgico y los exámenes aislados de coagulación no constituyen un buen predictor del sangrado perioperatorio.

Abstract: Introduction: Coagulation tests are no value to determine the risk of perioperative bleeding. Material and methods: An observational descriptive cross-sectional study was carried out in 2,114 patients in the anesthesiology consultation of the University Hospital «Dr. Celestino Hernández Robau¼. Results: The clotting and bleeding time was performed in 100% of cases, the platels count in 93.99%. While the prothrombin time and activated partial tromboplastin time were performed in 66.27 and 55.62% respectively. Of 8,834 tests carried out, 49 were found to be altered for 0.55%. Patients with altered tests were for 1.56%, patients at risk of bleeding from coagulation tests were 30 for 1.42% and patients at risk with no history of bleeding detected by coagulation tests were three for 0.14%. Perioperative bleeding was reported in 16 patients for 0.76%, seven patients with positive questioning and normal tests and nine patients with negative questioning and normal tests. Conclusions: The patient's medical history and physical examination are the best tools to predict the risk of surgical bleeding and isolated coagulation tests do not constitute a good predictor of perioperative bleeding.

Argon Beam Coagulation as an Adjuvant for Extended Curettage for Giant Cell Tumors of the Bone: A Study of 50 Cases / Coagulação por plasma de argônio como adjuvante à curetagem estendida em tumores de células gigantes do osso: Um estudo de 50 casos

Abstract Objective Extended curettage with adjuvants of giant cell tumors of bone is associated with a lower rate of recurrence of the tumor while preserving the adjacent joint. The present study was conducted to estimate the recurrence rate and functional outcome after using argon beam as an adjuvant for extended curettage. Methods We selected 50 patients with giant cell tumors, meeting all the inclusion criteria, who underwent extended curettage using high speed burr and argon beam photocoagulation between July 2016 to January 2019. On their follow-up visit, they were assessed for any complaints of pain and signs like tenderness, locally raised temperature, and decreased range of motion of the adjacent joint. Radiologically, the patients were assessed for any increased lucency around the cement mantle and uptake of the subarticular graft. Musculoskeletal Tumor Society Score (MSTS) was administered to the patients, and range of motion of the adjacent joint was compared with the contralateral joint. Results Recurrence was found in 4 patients, that is, an 8% recurrence rate. Twenty-six out of 28 patients with a tumor in the lower limb had a grade-5 weight bearing status 6 months from the surgery, and their range of motion was comparable to contralateral healthy joint with an average MSTS score of 27 (18-30). Conclusion Extended curettage of giant cell tumors using argon beam coagulation is associated with low recurrence rates of the tumor and is an effective modality in the treatment of these tumors besides having a functional outcome comparable to the healthy limb.

Resumo Objetivo A curetagem estendida com adjuvantes de tumores de células gigantes do osso está associada a uma menor taxa de recidiva da neoplasia e à preservação da articulação adjacente. Este estudo foi feito para estimar a taxa de recidiva e o resultado funcional após o uso de plasma de argônio como adjuvante à curetagem estendida. Métodos Cinquenta pacientes com tumores de células gigantes que atendiam a todos os critérios de inclusão foram selecionados para o estudo e submetidos à curetagem estendida com broca de alta velocidade e fotocoagulação com plasma de argônio entre julho de 2016 e janeiro de 2019. À consulta de acompanhamento, os pacientes foram avaliados quanto a quaisquer queixas de dor e sinais como sensibilidade, aumento local da temperatura e diminuição da amplitude de movimento da articulação adjacente. Radiologicamente, os pacientes foram avaliados quanto à presença de qualquer aumento de radiotransparência ao redor do manto de cimento e incorporação do enxerto subarticular. O questionário Musculoskeletal Tumor Society Score (MSTS) foi administrado aos pacientes e a amplitude de movimentação da articulação adjacente foi comparada à articulação contralateral. Resultados Quatro pacientes apresentaram recidiva, o que corresponde a uma taxa de 8%. Seis meses após a cirurgia, 26 de 28 pacientes com tumor no membro inferior tinham capacidade de sustentação de peso de grau 5 e amplitude de movimento comparável à articulação saudável contralateral, com pontuação MSTS média de 27 (intervalo de 18 a 30). Conclusão A curetagem estendida de tumores de células gigantes com coagulação por plasma de argônio está associada a baixas taxas de recidiva da neoplasia; é uma modalidade eficaz no tratamento desses tumores e o resultado funcional é comparável ao do membro saudável.

Analysis of APTT Mixing Test Results in Factor Ⅷ Inhibitor-Positive Hemophilia Patients / 中国实验血液学杂志

OBJECTIVE@#To analyze the results of activated partial thromboplastin time (APTT) mixing test in coagulation factor Ⅷ inhibitor-positive hemophilia patients, so as to increase the value of APTT mixing test in the screen of factor Ⅷ inhibitor.@*METHODS@#Eighty plasmas samples with different titers of coagulation factor Ⅷ inhibitors had been collected and diluted for routine immediate APTT mixing test and at 37 ℃ 2 hours incubation APTT mixing test. Fifteen samples were selected for immediate and normal temperature incubation for 15 min, 30min, 1 hour, 2 hours and 37 ℃ for 30 min, 1 hour, 2 hours APTT mixing test.@*RESULTS@#The results of APTT mixing test were significantly correlated with the titers of coagulation factor Ⅷ inhibitors. The ROC curve result showed that the best diagnostic cut-off value for 2 hours incubation APTT mixing test at 37 ℃ to determine the presence or absence of coagulation factor Ⅷ inhibitors was 43.8 s (sensitivity and specificity was 85.90% and 100%, respectively), while the best diagnostic cut-off value for distinguishing high-titer and low-titer Ⅷ inhibitors was 52.4 s (sensitivity and specificity was 98.18% and 95.65%, respectively). The critical coagulation factor Ⅷ inhibitor titer that could not be corrected by immediate APTT was 5.14 BU/ml, while that could not be corrected by 37 ℃ 2 hours incubation APTT was 1.31 BU/ml. Paired samples t -test was performed on the APTT mixing test results at different times and temperatures, and the differences were statistically significant (P < 0.05).@*CONCLUSIONS@#The APTT mixing test can be used as a screening index for coagulation factor Ⅷ inhibitors. APTT mixing test result shows a significant time-temperature dependence with lower titers of coagulation factor Ⅷ inhibitor. Patients with hemophilia who cannot be corrected by immediate APTT mixing test should be alert to the possibility of high titer of coagulation factor Ⅷ.

Why anticoagulant studies on sepsis fail frequently --- start with SCARLET / 中华创伤杂志(英文版)

The Sepsis Coagulopathy Asahi Recombinant LE Thrombomodulin (SCARLET) trial has many defects, and thus cannot be the terminator of recombinant thrombomodulin (rTM). On the contrary, it provides sufficient evidence for further research. Based on analysis focusing on the failure of SCARLET and several previous anticoagulant studies, it is most important for new studies to grasp the following two points: (1) The enrolled cases should have sufficient disease severity and a clear standard for disseminated intravascular coagulation; (2) Heparin should not be used in combination with the investigated drugs. Multiple post-hoc analyses show that no combination of heparin will not increase the risk of thromboembolism. In fact, the combination of heparin can mask the true efficacy of the investigated drug. Due to the complexity of sepsis treatment and the limitations of clinical studies, the results of all treatment studies should be repeatedly verified, rather than be determined at one stroke. Some research conclusions contrary to disease physiology, pharmacology and clinical practice may be deceptive, and should be cautious rather than be simply accepted. On the other hand, the dissenting voices in the "consensus" scene are often well discussed by the authors and should be highly valued.

The Osseous Pathology of Purpura Fulminans in a TwoYear-Old Child: A Case Report

@#Purpura fulminans (PF) is a severe clinical manifestation of Neisseria meningitides infection that is associated with high mortality rates in children. Survivors are frequently left with debilitating musculoskeletal sequelae. There is a paucity of reports on the musculoskeletal pathology of purpura fulminans. We report on a 2-year-old boy with purpura fulminans due to meningococcemia. The child developed distal gangrene in both the upper and lower limbs. Amputations were done for both lower limbs. Histological examination of the amputated specimens showed an inflammatory process and features of osteonecrosis. The latest follow-up at the age of 6 years showed a right knee valgus due to asymmetrical growth arrest of the proximal tibia. PF and its complications are challenging to treat and may require a multidisciplinary approach to improve patient’s functional ability.

Effects of acute normovolemic hemodilution combined with intraoperative recycled autotransfusion on blood transfusion volume and coagulation function in elderly patients undergoing cardiac surgery / 中国输血杂志

【Objective】 To explore the effects of acute normovolemic hemodilution (ANH) combined with intraoperative recycled autotransfusion on blood transfusion volume and coagulation function in elderly patients undergoing cardiac surgery. 【Methods】 A total of 94 elderly patients undergoing cardiac surgery in the hospital were enrolled and randomly divided into observation group (n=47) and control group (n=47) between March 2020 and March 2022. The observation group was given ANH combined with intraoperative recycled autotransfusion, while control group was given routine allogeneic transfusion. The blood transfusion volume, oxygenation status, immune function, inflammatory indexes and adverse reactions in the two groups were compared. 【Results】 The banked blood transfusion volume was less in observation group than control group [(1.73±0.43) U vs (5.71±1.71) U, P<0.05]. At 6 h after surgery, blood oxygen saturation (SvO2) level was higher [(74.59±7.20) % vs (67.22±6.19) %], while oxygen uptake rate (ERO2) level was lower[(0.29±0.06) % vs (0.34±0.05) %] in observation group than control group (P<0.05). At day 1 after surgery, levels of CD3+, CD4+, CD4+ /CD8+ and natural killer cells (NK) were higher [(65.11±5.14) %, (46.93±5.17) %, (1.86±0.30), (8.35±1.23) % vs (57.45±7.24) %, (43.58±4.85) %, (1.47±0.36)%, (7.34±1.38) %], while CD8+ was lower [(25.17±4.01) % vs (30.39±5.06) %] in observation group than control group (P<0.05). At day 1 after surgery, levels of serum interleukin 6/8 (IL-6/8) and tumor necrosis factor-α (TNF-α) were lower in observation group than control group [(104.51±12.55) ng/L vs (125.81±14.96) ng/L, (351.42±52.86) ng/L vs (394.27±55.78) ng/L, (254.93±49.94) ng/L vs (323.60±52.63) ng/L, P<0.05]. The incidence of adverse reactions was lower in observation group than control group (4.26% vs 17.02%), P<0.05. 【Conclusion】 Recycled autotransfusion can reduce allogeneic transfusion volume in elderly patients undergoing cardiac surgery. There is no difference in the effects on blood routine or coagulation function between recycled autotransfusion and allogeneic transfusion. Compared with allogeneic transfusion, recycled autotransfusion can significantly improve oxygenation status, relieve immunosuppression and inflammation response, and reduce the risk of adverse reactions.

Effect of intraoperative cell salvage on allogeneic blood transfusion requirements, coagulation function and electrolytes in postpartum hemorrhage of cesarean section / 中国输血杂志

【Objective】 To explore the effect of intraoperative cell salvage on allogeneic blood transfusion requirements, coagulation function and electrolytes in postpartum hemorrhage patients. 【Methods】 A study on postpartum hemorrhage patients undergoing cesarean section in the Third Affiliated Hospital of Guangxi Medical University form September 2016 to May 2022 was conducted retrospectively. A total of 137 patients were enrolled and divided into experimental group (n=70) and control group (n=67) according to whether intraoperative cell salvage was used during operation. The blood loss, proportion and volume of allogeneic red blood cells (RBCs) and coagulation component transfusion, hemoglobin (Hb) level, coagulation function, electrolyte, the incidence of complications, proportion of ICU admission, ICU stay and in-hospital stay were compared between the two groups. 【Results】 The proportion of patients receiving allogeneic RBCs in the experimental group and in the control group was 31.4% vs 100.0% (P0.05). 【Conclusion】 This study demonstrated that intraoperative cell salvage could reduce the requirement for allogeneic RBCs without compromising coagulation function in postpartum hemorrhage patients undergoing cesarean section, but the changes of calcium need to be concerned after transfusion.

Quality evaluation of cryoprecipitate coagulation factors from buffy coat-derived plasma at different time periods / 中国输血杂志

【Objective】 To investigate the quality of cryoprecipitates prepared from buffy coat-derived plasma of fresh whole blood at room temperature 20℃-24℃ isolated at different time periods, explore the optimal time for preparing cryoprecipitates, so as to improve the utilization rate of blood. 【Methods】 A total of 250 bags of whole blood collected by CPDA-1 and stored at 20℃-24℃ from October 2020 to December 2020 were randomly selected as the experimental group, and divided into groups A1 (0-8 h), A2 (8-10 h), A3 (10-12 h), A4 (12-14 h) and A5 (14-16 h) (with 50 bags in each group) according to the preparation time point. The upper-buff-coat plasma was separated and quickly frozen as the source for cryoprecipitates. Meanwhile, another 50 bags of fresh frozen plasma prepared within 0-16h after routine storage at 2℃-6℃ were randomly selected as the control group (group B), which was used as the raw plasma to make cryoprecipitate. Coagulation factor Ⅷ (Ⅷ factor) and fibrinogen (FIB) were detected, and the effect of different preparation time and different storage temperature on the content of factor Ⅷ and FIB and the pass rate were compared. 【Results】 In comparison to the control group, the Ⅷ factor content of groups A4 and A5 was significantly decreased, and the differences between groups A4, A5 and B were statistically significant (P0.05). The Factor Ⅷ content ≥60 IU/ bag prepared from buffy coat-derived plasma accounted for 96.4% (1.5 U) in the experimental group. 【Conclusion】 The buffy coat-derived plasma prepared within 12 h at 20℃-24℃ is suitable for preparing 2 U cryoprecipitate coagulation factor, while that prepared within 12-16 h is suitable for preparing 1.5 U cryoprecipitate coagulation factor.

Effect of recombinant human coagulation factor Ⅶa combined with Bakri balloon compression on oxidative stress and coagulation in patients with refractory postpartum hemorrhage / 中国输血杂志

【Objective】 To investigate the effects of recombinant human coagulation factor Ⅶa combined with Bakri balloon compression on oxidative stress and coagulation in patients with refractory postpartum hemorrhage. 【Methods】 Prospectively, 80 patients with refractory postpartum hemorrhage in Chengdu Fifth People′s Hospital from June 2019 to June 2022 were selected and grouped according to the random number table method. The control group (n=40) was treated with Bakri balloon compression, and the observation group (n=40) was treated with recombinant human coagulation factor Ⅶa combined with Bakri balloon compression. The bleeding-related indexes and adverse effects were observed in both groups, and the prenatal and 24 h postpartum oxidative stress, coagulation function and inflammatory factors were compared between the two groups. 【Results】 The blood loss in the observation group and the control group was (683.96±146.52) vs(796.63±152.41)mL during operation, (812.46±161.53) vs(965.39±166.22)mL in 2 h after delivery, (899.53±178.74) vs(1 084.31±203.67)mL in 24 h after delivery, and the transfusion volume was (512.31±104.76) vs(683.25±113.52)mL, and the onset time of hemostasis was (14.63±3.18) vs (21.72±5.29) min (P0.05). At 24 h postpartum, NE, Cor, SOD and MDA were higher than those before delivery in both groups, but the observation group was lower than the control group (P<0.05); TT, APTT and PT were longer and Fib was lower in both groups than before delivery, but TT, APTT and PT were shorter and Fib was higher in the observation group than in the control group (P<0.05); CRP, IL-8 and TNF-α were higher in both groups than before delivery, but the observation group was lower than in the control group (P<0.05). 【Conclusion】 Hemostasis in patients with refractory postpartum hemorrhage treated with recombinant human coagulation factor Ⅶa combined with Bakri balloon compression was effective, which can improve coagulation, reduce transfusion, decrease oxidative stress injury and inflammatory response without increasing adverse effects.
