Objective To summarize the clinical features,serological features,blood transfusion protocols and treatment of 3 cases of passenger lymphocyte syndrome(PLS)after ABO-incompatibility liver and renal transplantation in our hospital,in order to provide guidance for comprehensive clinical understanding and recognition of this disease,especially early recogni-tion and treatment.Methods By collecting the basic information of the patients and the time of cross-matching incompatibility of homologous blood after transplantation,observing the skin yellow staining,detecting hemoglobin value and other hemolysis indexes,and blood group serological detection results before and after transfusion,the diagnosis and analysis were performed.The diagnosis and treatment effect of PLS were analyzed by collecting the clinical outcome information after immunization and blood transfusion.Results Three cases of ABO-incompatible liver transplantation showed decreased hemoglobin and hemoly-sis,incompatible cross-matching of homologous blood,and anti-A and anti-B IgG antibodies were confirmed by serological test.After treatment such as immunosuppression and plasma exchange,blood transfusion was effective,hemolysis was im-proved,and antibodies gradually disappeared.Conclusion ABO blood group antibody screening,unexpected antibody screening and direct antiglobulin test(DAT)should be performed regularly for ABO-incompatible liver and renal transplantation cases,in order to detect the PLS early.A series of laboratory tests related to PLS should be performed in time to diagnose and adjust the treatment plan,including transfusion strategy,when homologous cross-matching is incompatible.

Objective:To investigate the facilitators and hindrances of smoking cessation in patients with chronic obstructive pulmonary disease (COPD), and to provide a basis for developing individualized smoking cessation intervention strategies for COPD patients.Methods:Based on the health ecology theory and using a phenomenological approach in qualitative research, purposive sampling was used to select 15 COPD patients with smoking history who were admitted to Tianjin Fourth Central Hospital from March to May 2023 and face-to-face semi-structured interviews were conducted. Colaizzi seven-step analysis was used to analyze the interview content.Results:A total of 15 COPD patients were interviewed, including 13 males and 2 females, aged 61-75 years old. The facilitators of smoking cessation in COPD patients included complications, sequelae of novel coronavirus infection, fear of death, smoking cessation counseling by medical staff, heavy family financial burden, and smoke-free environment. The hindrances of smoking cessation in COPD patients included milder disease symptoms of COPD, higher levels of nicotine dependence, false disease-related perceptions, family supervision and control, and occupational experience.Conclusions:Smoking cessation in COPD patients is influenced by five factors: personal characteristics, behavioral characteristics, interpersonal network, living and working conditions, and policy environment. Medical staff and relevant national institutions should formulate corresponding smoking cessation strategies according to address the facilitators and hindrances of smoking cessation in COPD patients, so as to further reduce the smoking prevalence of COPD patients, promote the health of patients and reduce the burden of disease.

Objective To investigate the prognostic value of plasma thrombomodulin(TM)in patients with septic shock.Methods A retrospective analysis was conducted on the clinical data of 180 patients with septic shock admitted to the intensive care unit of the 908th Hospital from May 2018 to November 2022.The patients were divided into survival group(106 cases)and death group(74 ca-ses)based on the 30-day follow-up outcomes.Propensity score matching(PSM)was used to match 57 surviving patients with 57 de-ceased patients in a 1∶1 ratio,based on confounding factors such as age,gender,underlying diseases,primary infection site,laborato-ry results and disease severity scores.TM and other coagulation molecular markers were compared between the two groups,and logistic regression,receiver operating characteristic(ROC)curve,survival and correlation analyses were performed.Results After PSM,the TM levels in the death group(18.3[13.2,22.3]TU/mL)were significantly higher than those in the survival group(13.7[9.0,18.3]TU/mL)(P＜0.05).Multivariate logistic regression analysis showed that TM was an independent risk factor for 30-day mortality in the patients with septic shock(OR=1.137,95％CI:1.023-1.262,P＜0.005).ROC curve analysis revealed that the areas under the curve(AUCs)for predicting 30-day mortality were 0.665,0.627 and 0.600 for TM,Acute Physiology and Chronic Health EvaluationⅡ(APACHE Ⅱ)and Sequential Organ Failure Assessment(SOFA)scores,respectively.Kaplan-Meier survival analysis stratified by the optimal TM cut-off value(17.9 TU/mL)showed that the 30-day survival rate of the TM＜17.9 TU/mL group was 1.56 times that of the TM≥17.9 TU/mL group(Log-Rank test,P＜0.000 1).Spearman correlation analysis demonstrated that TM levels were positively correlated with APACHE Ⅱ(r=0.10,P＜0.005)and SOFA scores(r=0.35,P＜0.005).Conclusion Plasma TM has showed a good predictive value for assessing the prognosis of patients with septic shock and may serve as a potential biomarker for determining the prognosis of septic shock.

Objective To investigate the clinical values of heparinase-modified thromboelastography(hmTEG)in heparin monitoring during continuous renal replacement therapy.Methods A total of 97 cases who were undergoing continuous renal replacement therapy(CRRT)in the intensive care unit of the 94th People's Liberation Army Hospital from Jan 2014 to Jun 2019 were enrolled in this stud-y.The patients were divided into TEG group and APTT group according to different means of heparin monitoring during continuous renal replacement therapy.In total,278 hemofilters were used in all the blood purification therapies.Complication of bleeding,CRRT time,total heparin dose and SOFA(sequential organ failure assessment)score of the patients were compared between the TEG and APTT groups.The filter life span and survival time in hospital were also compared using Kaplan-Meier analysis.Rusults Compared with APTT group,the total heparin dose in TEG group were significantly higher(P＜0.05).The CRRT time of patients and the average filter life span in TEG group were significantly longer than those of APTT group(P＜0.05).Compared to APTT group,the 28-day SOFA in TEG group was significantly lower(P＜0.05).Survival analysis showed that the 28-day risk of death in the patients of APTT group was 2.01 times higher than that in TEG group(P＜0.05).The 72-hour filter life of TEG group was significantly longer than that of APTT group(P＜0.05).Conclusion The use of hmTEG for monitoring heparin in blood purification should be superior in terms of safety and efficacy with longer filter life span and higher survival rate of patients.

Objective:To investigate the clinical significance of plasma thrombin-antithrombin complex (TAT) levels in patients with sepsis-induced cardiomyopathy(SIC).Methods:One hundred and seven sepsis patients who were admitted to intensive care units (ICU) of the 908th Hospital of Chinese PLA Logistical Support Force were enrolled in the study. Patients were divided into sepsis group ( n=79) and the sepsis-induced cardiomyopathy group ( n=28) according to whether the cardiac ultrasound examination in 2 hours after admission, and the differences of each indicators between the two groups were compared including acute physiological and chronic health score (APACHEⅡ), lactate, blood routine, liver and kidney function, cardiac troponin I, N-terminal?pro-brain?natriuretic?peptide (NT-pro BNP), conventional coagulation tests and molecular markers of coagulation [tissue plasminogen activator-inhibitor complex (t-PAIC), thrombomodulin (TM), TAT, plasmin-α2-plasmin inhibitor complex (PIC)].Logistical?regression?was?used?to analyze the?risk?factors?for sepsis-induced cardiomyopathy and the receiver operating characteristic (ROC) curve was to analyze their cut-off values. The effect of low-molecular-weight heparin anticoagulation therapy on sepsis patients with TAT>8.26 ng/ml was evaluated by Kaplan-Meier analysis. Results:Compared with the cardiac troponin I[0.02(0.01, 0.09) ng/ml], NT-proBNP [1 118.09 (333.25, 2687.00) pg/ml], lactate[1.35(0.90, 2.60) mmol/L], TAT[6.50(3.94, 12.14) ng/ml], PIC[1.256 (0.668, 2.045) μg/ml] and t-PAIC[10.50 (6.70, 21.30) ng/ml] in sepsis group, the cardiac troponin I [0.75(0.01, 6.02) ng/ml], NT-proBNP[12 125.14(4 185.89, 33 611.62) pg/ml], lactate[2.35(1.43, 4.34) mmol/L], TAT[19.85 (9.08, 45.78) ng/ml], PIC[2.115 (0.878, 4.114) μg/ml] and t-PAIC [22.03(15.61,33.20) ng/ml] levels in the sepsis-induced cardiomyopathy group were significantly increased ( P<0.05). Logistical regression showed that positive NT-pro BNP and elevated TAT levels were independent risk factors for sepsis-induced cardiomyopathy. ROC curve analysis showed that the area under the curve of plasma TAT level for predicting sepsis-induced cardiomyopathy was 0.78. The sensitivity and specificity at the cut-off value of plasma TAT level with 8.26 ng/ml were 0.82 and 0.63, respectively. Conclusions:The elevated TAT level was an independent risk factor for the development of sepsis-induced cardiomyopathy. Low-molecular-weight heparin anticoagulation therapy can improve the 28-day survival rate of sepsis patients with TAT>8.26 ng/ml.
