ABSTRACT
Objective To analyze the core genes of lung ischemia-reperfusion injury and construct a competitive endogenous RNA (ceRNA) network. Methods Original data of GSE145989 were downloaded from the Gene Expression Omnibus (GEO) database as the training set, and the GSE172222 and GSE9634 datasets were used as the validation sets, and the differentially-expressed genes (DEG) were identified. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed. Protein-protein interaction (PPI) network was constructed, and the core genes were screened, and the diagnostic values of these core genes and the immune infiltration levels of immune cells were evaluated. The ceRNA network was constructed and validated. The targeted drugs based on ceRNA network were assessed. Results A total of 179 DEG were identified, including 61 down-regulated and 118 up-regulated genes. GO analysis showed that DEGs were associated with multiple biological processes, such as cell migration, differentiation and regulation, etc. They were correlated with cell components, such as vesicle membrane, serosa and membrane raft, etc. They were also associated with multiple molecular functions, such as chemokine receptor, G protein-coupled receptor, immune receptor activity and antigen binding, etc. KEGG pathway enrichment analysis revealed that DEG were involved in tumor necrosis factor (TNF), Wnt, interleukin (IL)-17 and nuclear factor (NF)-κB signaling pathways, etc. PPI network suggested that CD8A, IL2RG, STAT1, CD3G and SYK were the core genes of lung ischemia-reperfusion injury. The ceRNA network prompted that miR-146a-3p, miR-28-5p and miR-593-3p were related to the expression level of CD3G. The miR-149-3p, miR-342-5p, miR-873-5p and miR-491-5p were correlated with the expression level of IL-2RG. The miR-194-3p, miR-512-3p, miR-377-3p and miR-590-3p were associated with the expression level of SYK. The miR-590-3p and miR-875-3p were related to the expression level of CD8A. The miR-143-5p, miR-1231, miR-590-3p and miR-875-3p were associated with the expression level of STAT1. There were 13 targeted drugs for CD3G, 4 targeted drugs for IL-2RG, 28 targeted drugs for SYK and 3 targeted drugs for lncRNA MUC2. No targeted drugs were identified for CD8A, STAT1 and other ceRNA network genes. Conclusions CD8A, IL2RG, STAT1, CD3G and SYK are the core genes of lung ischemia-reperfusion injury. The research and analysis of these core genes probably contribute to the diagnosis of lung ischemia-reperfusion injury and providing novel research ideas and therapeutic targets.
ABSTRACT
ObjectiveTo investigate the efficacy and safety of cinobufagin tablets combined with thalidomide/dexamethasone （TD） regimen in the treatment of newly diagnosed multiple myeloma （NDMM） with phlegm and stasis obstruction. MethodsThe clinical data of 50 patients with NDMM of phlegm and stasis obstruction who were hospitalized at the Jiangsu Province Hospital of Chinese Medicine from June 1st， 2015 to July 31th， 2019 were retrospectively analyzed， and they were divided into a control group （bortezomib/dexamethasone-containing regimen， 27 cases） and an observation group （cinobufagin tablets combined with TD regimen， 23 cases）. The clinical efficacy and safety were compared between the two groups after two or three courses of treatment. The primary outcomes were clinical remission rate including overall response rate and deep remission rate， one-year and two-year overall survival rate， and adverse effects. The secondary outcomes were the proportion of plasma cells in bone marrow， hemoglobin， β2-microglobulin， lactate dehydrogenase， serum creatinine， blood urea nitrogen， bone pain score， and KPS functional status score （KPS score） before and after treatment. ResultsIn terms of clinical efficacy， there was no statistically significant difference （P＞0.05） in the overall response rate ［the observation group 69.57%（16/23） vs the control group 70.37% （19/27）］ and deep remission rate ［the observation group 56.52% （13/23） vs the control group 55.56% （15/27）］ between groups after the treatment. The one-year overall survival rates of the observation group and the control group were 90.9% and 92.4%， and the two-year overall survival rates were 81.8% and 80.9% respectively， with no statistically significant differences between groups （P＞0.05）. During the treatment， no renal function injury occurred in both groups. The incidence of peripheral nerve injury in the observation group was 8.70%， which was lower than 48.15% in the control group （P＜0.01）. After the treatment， the proportion of myeloma plasma cells， β2-microglobulin， serum creatinine level， and bone pain score decreased， while the hemoglobin level and KPS score increased in both groups （P＜0.05 or P＜0.01）. Compared between groups after treatment， the bone pain score of the observation group was lower than that of the control group， while the KPS score was higher than that of the control group （P＜0.05）. ConclusionThe clinical efficacy of cinobufagin tablets combined with TD in the treatment of NDMM is equivalent to bortezomib/dexamethasone-containing regimen， but the former is more helpful in relieving the pain and improving the quality of life， and has better safety.
ABSTRACT
【Objective】 To investigate the risk factors of transfusion-related circulating overload (TACO) in hospitalized patients and to analyze its impact on clinical outcome. 【Methods】 The clinical data of 295 patients with blood transfusion admitted to our hospital from June 2020 to June 2022 were retrospectively analyzed. The patients were divided into TACO group (n=23) and control group (n=272) according to the incidence of TACO. The risk factors of TACO were analyzed by Logistic regression, and the differences of hospital stay and mortality between the TACO group and the control group were compared. 【Results】 TACO occurred in 23 of 295 patients, accounting for 7.80% of all transfusion reactions. The incidence of TACO in different transfusion components was different. Elder age, history of heart failure, history of chronic kidney disease, large mean blood transfusion volume, positive fluid balance [OR(95%CI)): 2.022 (1.212-3.372), 1.917(1.258-2.922), 1.719 (1.155-2.560), 2.252 (1.256- 4.039), 2.221 (1.358-3.633)] were the main risk factors for TACO (P<0.05). 【Conclusion】 Elder age, history of heart failure, history of chronic kidney disease, large blood transfusion volume and positive fluid balance were risk factors for TACO, and TACO was associated with increased length of stay and mortality during hospitalization.
ABSTRACT
Objective:To evaluate perioperative coagulatory parameters and transfusion rates of lung transplantation recipients.Methods:Clinical data were retrospectively reviewed for 178 lung transplant recipients at China-Japan Friendship Hospital from March 2017 to July 2019. According to whether extracorporeal membrane oxygenation(ECMO)was used during perioperative period, they were divided into two groups of ECMO(131 cases)and without ECMO(47 cases). Clinical data, laboratory examinations and blood transfusion status of two groups were compared. In ECMO group, excluding secondary thoracotomy for hemostasis(7 cases)and incomplete data(2 cases), the remainders were divided into the groups of no red blood cell transfusion(63 cases), red blood cell transfusion(59 cases), plasma transfusion <1 000 ml(99 cases)and plasma transfusion≥1 000 ml (23 cases), no platelet transfusion(93 cases)and platelet transfusion(29 cases). Clinical data, laboratory examinations and ECMO-related parameters of recipients were analyzed by Bary Logistic regression.Results:Statistically significant inter-group differences existed in body mass index(BMI), disease course, primary disease, bilateral lung transplantation, laboratory examinations, postoperative blood transfusion volume, postoperative red blood cell and plasma transfusion ratio between groups with and without ECMO( P<0.05). Bilateral lung transplantation, ASA grade, differences in BMI, disease course, postoperative hemoglobin<100 g/L, postoperative PT/APTT/INR abnormalities and postoperative PLT count <100×10 9/L were independent risk factors for postoperative transfusion during ECMO. Conclusions:The application of ECMO during lung transplantation may affect the perioperative transfusion volume and demand.Fully assessing blood transfusion requirements, optimizing coagulation monitoring and identifying the independent influencing factors of postoperative blood transfusion facilitate clinical scientific and rational blood transfusions.
ABSTRACT
【Objective】 To explore the influencing factors of perioperative red blood cell transfusion in patients underwent lung transplantation, so as to provide reference for perioperative blood management (PBM) of lung transplantation patients. 【Methods】 The clinical data of 173 lung transplant patients completed in China-Japan Friendship Hospital from March 2017 to June 2019 were retrospectively analyzed. The patients were divided into two groups according to perioperative red blood cell transfusion volume: large blood transfusion group (transfusion red blood cell volume ≥6 U, n=66) and non-large blood transfusion group (red blood cell transfusion volume <6 U, n=107). The basic information, preoperative laboratory test results, and surgical status of the two groups were statistically analyzed.The clinical data of the two groups were analyzed by univariate analysis. The factors of P<0.15 were included in the binary logistic regression analysis, and the independent influencing factors of perioperative massive blood transfusion in patients with lung transplantation were found. 【Results】 Univariate analysis of clinical data of the two groups of patients (large blood transfusion group vs. non-large blood transfusion group) showed that the differences of smoking history ratio [44(66.7%) vs 87(81.3%)], BMI(20.8±4.5 vs 22.5±4.0)(P<0.05), preoperative Hb [124(111, 138.8) vs 138(126, 149)], preoperative Hct [37.9(34.8, 42.5) vs 41.3(37.9, 44.6)], surgery duration(327.9±107.7 vs 238.4±77.0), intraoperative blood loss(1 108.6±1342.0 vs 341.8±270.8) and single lung transplantation [28(42.4%) vs 84(78.5%)] (P<0.01) were statistically significant. Logistic regression analysis showed that intraoperative blood loss (OR=1.001, P<0.05), surgery duration (OR=1.006, P<0.05), preoperative Hb (OR=0.973, P<0.01), lung transplantation type(single or double lung transplantation)( OR=0.247, P<0.05) and extracorporeal membrane oxygenation (ECMO) (OR=0.187, P<0.01) were independent factors influencing red blood cell transfusion during lung transplantation. 【Conclusion】 Intraoperative blood loss and surgery duration are risk factors for massive blood transfusion during the perioperative period. And the use of ECMO, preoperative Hb, single lung transplantation (compared to double lung transplantation) are protective factors for perioperative massive blood transfusion.
ABSTRACT
【Objective】 To study the effect of intravenous immunoglobulin(IVIG) on the detection of blood transfusion compatibility in patients. 【Methods】 56 patients, submitted to our Hospital from March 1, 2017 to December 31, 2020, were enrolled as the research objects. They had negative unexpected antibody screening, major crossmatch incompatibility with the same blood type donors, and had a history of IVIG infusion. ABO and RhD blood groups typing, unexpected antibodies screening, crossmatch, direct antiglobulin test, indirect antiglobulin test, and acid elution test were all conducted by microcolumn gel method. 【Results】 After IVIG infusion, the initially major crossmatch incompatibility with the same blood type donors turned into compatiblity with O-type donors. Among them, 2 patients had transient discrepancy in ABO forward and reverse blood typing due to the IVIG infusion. IgG anti-A were detected in the red blood cell elution of 37 A-type patients; IgG anti-B in 2 B-type patients; 3 cases of IgG anti-A+ anti-B and 14 cases of solo IgG anti-A in 17 AB-type patients. 3 batches of IVIG preparations were detected randomly, IgG anti-A titer was 32-64, and IgG anti-B titer was 8-16. 【Conclusion】 The discrepancy in ABO forward and reverse blood typing and major crossmatch incompatibility with the same blood type donors may occur after non-O type patients received IVIG, which contains IgG types of anti-A and anti-B. In this situation, it is recommended to prepare major crossmatched O-type washed red blood cells to ensure the safety and effectiveness of clinical blood transfusion.
