Objective:To evaluate the relationship between blood transfusion factors (massive transfusion, transfusion of stored red blood cells and anhepatic transfusion) and early postoperative outcomes in the patients undergoing orthotopic liver transplantation.Methods:Patients with end-stage liver disease who underwent orthotopic liver transplantation and intraoperative blood transfusion from January 2021 to March 2022 in our hospital were retrospectively selected, and their clinical data were collected. The patients were divided into massive transfusion group (M group, total red blood cell transfusion ≥10 U) and non-massive transfusion group (NM group) according to the amount of intraoperative blood transfused. The patients were divided into fresh blood group (NS group) and stored blood group (S group, red blood cell storage time > 2 weeks) according to the storage time of red blood cells transfused. The patients were divided into transfusion in anhepatic stage group (group T) and nontransfusion in anhepatic stage group (group NT) according to whether blood was transfused in the anhepatic stage. Multivariate logistic regression, generalized linear model and generalized linear mixed model were used to analyze the relationship between blood transfusion factors and primary outcome measures (postoperative pulmonary complications, circulation overload, acute kidney injury, abdominal infection, thrombosis) and between blood transfusion factors and secondary outcome measures (duration of ICU stay, postoperative hospitalization, postoperative temperature ≥38.5 ℃ at any time point after surgery, postoperative liver and kidney function index, coagulation function index, platelet count and preoperative difference).Results:One hundred and six patients were enrolled in this study. The results of multivariate logistic regression analysis: Massive blood transfusion and infusion of stored blood were risk factors for postoperative pulmonary complications, massive blood transfusion was a risk factor for abdominal infection, Child-Turcotte-Pugh score for liver function and time of anhepatic phase were risk factors for postoperative acute kidney injury, Child-Turcotte-Pugh score was a risk factor for circulatory overload, and age and massive blood transfusion were risk factors for thrombosis ( P<0.05). The results of generalized linear model analysis: Intraoperative stored blood transfusion and blood transfusion during the anhepatic phase were risk factors for prolonged duration of ICU stay, massive blood transfusion, intraoperative stored blood transfusion and blood transfusion during the anhepatic phase were risk factors for prolonged hospitalization ( P<0.05), and there was no correlation between massive blood transfusion, intraoperative stored blood transfusion and blood transfusion during the anhepatic phase and temperature ≥38.5 ℃ at any time point after surgery ( P>0.05). The results of generalized linear mixed model analysis: There was statistically significant difference in the difference between preoperative and postoperative liver and kidney function indexes, coagulation function indexes and platelet counts in the patients with or without massive transfusion, stored blood transfusion or blood transfusion during the anhepatic phase ( P<0.05). Conclusions:Massive blood transfusion and infusion of stored blood are the main risk factors for early adverse outcomes after orthotopic liver transplantation in the patients.

Obsjective To analyze the inflammation characteristics and changes of small airway function in patients with eosinophil and neutrophil asthma, and provide evidence for individualized treatment of asthma. Methods:Using a cross-sectional study, 46 patients with eosinophilic asthma and 42 patients with neutrophilic asthma confirmed by cytology of induced sputum were recruited from July 1, 2017 to June 30, 2019 at the respiratory Department of Respiratory Medicine,Jinshan Branch of the Sixth People's Hospital of Shanghai. Patients were divided by asthma category into eosinophilic asthma group and neutrophilic asthma group.The severity of acute attack, the score of asthma control test (ACT) and the concentration of serum C-reactive protein (CRP) were compared between the two groups The fraction of exhaled nitric oxide (FeNO), related cytokines(interleukin-4(IL-4), interleukin-5(IL-5), interleukin-13(IL-13), interleukin-17(IL-17) and interferon γ(IFN-γ)) in peripheral blood and induced sputum supernatant and lung function indicators (forced exhalation volume in one second (FEV1)% percent predicted (%pred), maximal mid-expiratory flow (MMEF)% pred, forced expiratory flow (FEF) 75% pred, forced expiratory flow at 50% of FVC exhaled (FEF50%) pred were detected. Independent sample t-test was used for the comparison between measurement data groups comforming to normal distritution, rank sum test was used for the comparison between measurement data groups not conforming to normal distribution, and χ 2 test was used for the comparison of counting data. Results:There were no significant differences in the general data and ACT scores between the two groups (all P>0.05). The ratio of severe and critical degree (52.38%(22/42)), uncontrolled and partially controlled patients (59.52%(25/42)), CRP level (24.6(7.1, 35.0) mg/L) in neutrophil asthma group were higher than those in eosinophilic asthma group(30.43% (14/46), 36.96% (17/46), and 8.5 (2.0, 12.0) mg/L, respectively) (χ 2=4.37, χ 2=4.48, Z=4.76; P=0.036, P=0.034, P<0.001). The concentration of FeNO was higher in eosinophilic asthma group (76(54,93) ppb) than that in neutrophil asthma group(27(15,41) ppb),and the differences was statistically significant ( Z=6.52, P<0.001). The values of FEV1% pred ((56.13±21.51)%), MMEF% pred ((62.03±23.97)%), FEF75% pred ((54.42±20.49)%), FEF50% pred ((66.89±26.47)%) in neutrophil asthma group were lower than those in eosinophilic asthma group ((68.53±29.81)%, (72.16±23.05)%, (65.38±25.46)% and (79.86±27.61)%), and the difference between the two groups was statistically significant( t values were 2.25, 2.02, 2.21, 2.24; P values were 0.027, 0.046, 0.030, 0.027). The concentrations of serum IL-4((49.42±24.46) ng/L), IL-5((104.89±43.91) ng/L) and IL-4((44.49±19.12) ng/L), IL-5((95.45±28.58) ng/L) in induced sputum supernatant were higher than neutrophilic asthma group((32.29±14.19), (50.35±22.30), (33.33±15.08), (55.61±26.41) ng/L). The difference between the two groups was statistically significant ( t values were 4.06, 7.44, 3.02, 6.77, P values were <0.001, <0.001, 0.003, <0.001). In eosinophilic asthma group, the concentrations of serum IL-13 ((76.18±20.62) ng/L), IL-17 ((31.32±9.32) ng/L), IFN-γ ((18.27±5.56) ng/L) and IL-13((71.08±20.08) ng/L), IL-17((26.29±6.70) ng/L), and IFN-γ((17.61±5.94) ng/L) in induced sputum supernatant were lower than those in neutrophilic asthma group((153.83±44.53 ) ng/L, (55.27±18.89) ng/L, (26.46±10.08) ng/L, (120.32±28.41) ng/L, (44.99±12.66) ng/L, (23.91±7.66) ng/L). The difference between the two groups was statistically significant ( t values were 10.33, 7.43, 4.66,9.31,8.54,4.33, respectively; all P<0.001). Conclusion:Eosinophilic asthma and neutrophil asthma have different inflammation, small airway function characteristics and different response to treatment. The small airway function changes in early stage of neutrophil asthma are more obvious.

Objective To evaluate the lung protection of residual pump blood processed by microaggregate blood filter-reinfusion in patients undergoing cardiac surgery under cardiopulmonary bypass (CPB).Methods A total of 40 patients,aged 28-55 yr,weighing 46-66 kg,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,with New York Heart Association of Ⅱ or Ⅲ,with left ventricular ejection fraction＞50％,scheduled for elective cardiac valve replacement under general anesthesia,were divided into 2 groups (n =20 each) using a random number table method:residual pump blood reinfusion group (group C) and residual pump blood processed by microaggregate blood filter-reinfusion group (group M).Residual pump blood was collected immediately after the end of CPB.The residual pump blood was stored in sterile blood collection bags without being filtered in group C.The residual pump blood was stored in sterile blood collection bags after being processed by microaggregte blood filter in group M.Residual pump blood was intravenously reinfused after the CPB pipe was removed.At 10 min before CPB (T1),immediately after the end ofCPB (T2),immediately after processing (T3) and at 12 and 24 h after residual pump blood reinfusion (T4,5),blood samples were collected to measure blood components and serum tumor necrosis factor-alpha and intedeukin-6 concentrations (by enzyme-linked immunosorbent assay).Airway plateau pressure was recorded,arterial blood samples were collected for blood gas analysis,and static lung compliance,oxygenation index and respiratory index were calculated at T1.5.The postoperative mechanical ventilation time,duration of intensive care unit stay,length of hospital stay,and incidence of hypoxemia and pulmonary infection were recorded.Results Compared with group C,white blood cell count was significantly decreased at T3-5,and static lung compliance and oxygenation index were increased,respiratory index was decreased,serum tumor necrosis factor-alpha and interleukin-6 concentrations were decreased,postoperative mechanical ventilation time and duration of intensive care unit stay were shortened,and the incidence of hypoxemia was decreased at T4.5 in group M (P＜0.05).Conclusion Residual pump blood proccessed by microaggregate blood filter-reinfusion can reduce systemic inflammatory responses and exerts lung protection to some extent in the patients undergoing cardiac surgery under CPB.

To evaluate effects of reinfusion of the remaining blood filtered by leukocyte depletion filter on postoperative cellular immune function after cardiopulmonary bypass (CPB). Methods Forty patients who underwent selective cardiac valve replacement surgery with CPB in department of anesthesiology of Haikou Municipal Hospital from January to June in 2018 were enrolled. All the patients were divided into the control group and experimental group according to the random number table method, with 20 patients in each group. In the experimental group, patients received residual pump blood transfusion which had been filtered by leukocyte depletion filter and stored in sterile blood collection bags. In the control group, patients received residual pump blood transfusion which was stored in sterile blood collection bags without being filtered. The remaining blood was reinfused after CPB in two groups. Blood samples were taken before CPB (T1), 2 hours following CPB (T2), and 1, 3, 5 days after reinfusion of the remaining blood (T3, T4, T5), the levels of T lymphocyte subsets CD3+, CD4+, CD8+ and natural killer cells (NK cells) were detected by flow cytometer, and CD4+/CD8+ ratio was calculated. The levels of plasma tumor necrosis factor-α (TNF-α), interleukins (IL-2, IL-6, IL-8) were measured by enzyme linked immunosorbent essay (ELISA). The duration of mechanical ventilation, the length of intensive care unit (ICU) stay, the length of hospital stay, and incidence of wound and pulmonary infection after surgery were compared between two groups. Results Among 40 patients, there were 22 males and 18 females; with an age of (47.88±12.29) years old; and with 25 cases of American Society of Anesthesiologists (ASA) physical status Ⅱ, and 15 cases of ASAⅢ. There was no statistical difference in the volume of the remaining blood between the two groups (mL: 959.00±116.84 vs. 971.50±115.68, P > 0.05). Compared with T1, the levels of T lymphocyte subsets CD3+, CD4+, CD8+, NK cells and plasma levels of IL-2 were significantly decreased from T2, the CD4+/CD8+ ratio was significantly decreased from T3 in two groups, but there was no statistical difference in CD3+, CD4+, CD8+, NK cells, CD4+/CD8+ ratio or plasma level of IL-2 at each time between the two groups. Compared with T1, the plasma levels of TNF-α, IL-6 and IL-8 were significantly increased at T2 in two groups and then decreased gradually. The plasma levels of TNF-α, IL-6 and IL-8 from T3 in experimental group were lower than those in control group [TNF-α (ng/L): 28.49±4.66 vs. 33.82±4.30, IL-6 (ng/L): 25.98±4.51 vs. 31.38±5.42, IL-8 (ng/L):38.98±4.67 vs. 45.76±5.33, all P < 0.05], they restored to the level of T1 at T5. In addition, compared with control group, the duration of mechanical ventilation, the length of ICU stay in experimental group were significantly decreased (hours: 8.07±1.30 vs. 9.16±1.52, 28.22±2.78 vs. 31.25±3.18, both P < 0.05), and there was no statistical difference in the length of hospital stay (days: 20.65±2.76 vs. 22.45±3.22), incidence of wound and pulmonary infection (25.0% vs. 15.0%, 5.0% vs. 15.0%) between the two groups (all P > 0.05). Conclusion Reinfusion of the remaining blood filtered by leukocyte depletion filtercan inhibit inflammatory responses and don't affect the function of cellular immunity, and don't increase the incidence of infection.

Objective To investigate the correlation between apolipoprotein E gene polymorphism and car-dio-cerebrovascular diseases. Methods Gene chip method was used to determine ApoE genotypes in 1427 pa-tients with cardiovascular disease and 450 health controls. Levels of serum lipid were compared. Results The highest genotype frequency of ApoE was ε3/3 in the patient group and control group. The allele frequency of ApoE from high to low wasε3,ε2 andε4. The genotype ofε3/3 in patient group was significantly lower than that in con-trol group(χ2 = 12.562,P < 0.01),whileε3/4 was significantly higher than that in control group(χ2 = 36.112, P < 0.01). No significant differences were found between patient groups in genotype or allele frequency of ApoE. The level of TCH,TG,LDL-c and sdLDL in the patient group were significantly higher than those in the control group,and HDL-c was significantly lower than those in the control group(P>0.05). The level of TCH and LDL-c significantly decreased in patients with E2 genotype,and increased in patients with genotype E4(P < 0.05). No significant differences were found in other indexes(P>0.05). Positive relationship was found between ApoE geno-type and phenotype of ApoE and LDL-c. Conclusions ApoE gene polymorphism plays an important role in the oc-currence and development of cardio-cerebrovascular diseases.

Objective This study examined the value of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1)in serum and exhaled ventilator condensate (EVC)in early diagnosis and prognosis of ventilator-associated pneumonia (VAP). Methods A total of 37 adult patients undergoing mechanical ventilation were evaluated after treatment,including 24 patients with infection,13 without infection.Of the 24 patients with infection,10 patients were assigned to ineffective subgroup and 14 to effective subgroup.Levels of sTREM-1 in serum and EVC were measured on days 1,3,5,and 7 for all patients.sTREM-1 in serum and EVC were determined in patients by double antibody sandwich enzyme-linked immunosorbant assay (DAS-ELISA).The early diagnostic and prognostic value was assessed by receiver operating characteristic (ROC)curve analysis.Re-sults On Day 1,the sTREM-1 levels in serum and EVC did not show significant difference between the three groups (P>0.05).On Day 3 and Day 5,the level of sTREM-1 in the infection group was higher than that in the non-infection group (P <0.01).On Day 7,the sTREM-1 levels of serum and EVC in ineffective subgroup were higher than those in the effective subgroup and non-infection group (P <0.01). There were no difference between the non-infection group and effective subgroup (P >0.05).For ROC analysis,area under the curve (AUC)of serum sTREM-1 was 0.897,and AUC of EVC sTREM-1 was 0.909 on Day 3.When the cut-off value of EVC sTREM-1 was set at 4.70 ng/mL on Day 3,the sensitivity was 85.8%,specificity was 92.3%.Conclusions The results suggest that the levels of sTREM-1 in serum and EVC are conducive to the early diagnosis of VAP.The levels of sTREM-1 in serum and EVC on Day 7 are helpful for estimating the prognosis.EVC sample is easier to collect than serum.

ObjectiveTo investigate the role of OPN in human breast cancer cell line ( MDA-MB-231) by using small interfering RNA to specifically knockdown OPN expression. MethodsOPN ShRNA expression vector was stably transfected to MDA-MB-231 cell line.The expression of OPN mRNA and protein were analyzed using reverse transcription polymerase chain reaction (RT-PCR)and Western blot,respectively.The growth of MDA-MB-231 cells were observed by MTT.The effect of OPN siRNA on the transplanted tumor growth and tumor hypoxia were assessed in nude mice. ResultsThe expression level of OPN in MDA-MB-231 cells were significantly lower under hypoxia or normoxia(P ＜ 0.05 ).OPN silence with RNAi significantly inhibited the invasion ability and proliferation of MDA-MB-231 cell lines (P ＜ 0.01 ).Inhibition of OPN with RNAi significantly inhibited the growth ability of MDA-MB-231 cells in vivo(P ＜0.05).The tumor hypoxia significantly decreased(P ＜ 0.05). ConclusionsOPN silence with RNAi can effectively inhibit cell proliferation and tumor growth of MDA-MB-231 cells,and decrease the bypoxia level of MDA-MB-231 transplanted tumor in nude mice.
