Objectives: To analyze the relationship between cardiac troponin I autoantibody (cTnIAAb) and left ventricular remodeling in patients with acute myocardial infarction (AMI). Methods: A total of 131 AMI patients were enrolled. Serum levels of cTnIAAb were measured by ELISA. Echocardiography was examined at the onset of AMI and 1 year follow-up evaluation. Taking left ventricular end systolic volume (LVESV) increasing>15% as left ventricular remodeling, 2-classified logistic stepwise regression analysis was conducted to screen 12 risk factors related to left ventricular remodeling. Results: 23/131(17.6%) patients were with positive cTnIAAb and 82.4% with negative cTnIAAb. 49 patients lost contact and in the rest 91 patients, 21.1% were with positive cTnIAAb. Clinical information was similar between cTnIAAb positive and negative patients upon admission, P>0.05; echocardiography showed that 28 (42.2%) patients had LVESV increasing>15% by 1 year follow-up study whom including 10 (52.6%) patients with cTnIAAb positive and 18 (25.4%) negative. 2-classified logistic stepwise regression analysis indicated that BNP peak and positive cTnIAAb were the risk factors for left ventricular remodeling (OR=1.001, 95% CI 1.001-1.002) and (OR=3.552, 95% CI 1.148-10.989), both P=0.028. Conclusions: Serum cTnIAAb was positive in part of AMI patients which was related to increased risk of left ventricular remodeling; cTnIAAb might be involved in pathophysiological process of left ventricular remodeling in AMI patients.

To evaluate the efficacy of an ultrasound-based quantitative method to diagnose liver fibrosis using a rat model. Ultrasonography was performed on the livers of 90 Sprague-Dawley rats with or without thioacetamide-induced fibrosis. The liver capsule thickness and 13 texture parameters of gray level co-occurrence matrix were extracted from the standard sonograms. After sacrifice, severity of liver fibrosis (S0-S4 classification) was diagnosed by histopathology. Analysis of variance and correlation statistical tests were used to analyze the differences between groups and determine the relationships between each of the 14 quantitative ultrasound index points and the histological results, respectively. Discriminant analysis models were developed for quantitative diagnosis of liver fibrosis, and the leave-one-case-out method was used to verify the efficiency of models. All 14 indices were significantly correlated with the histological stages of fibrosis (P less than 0.05). The accuracy of the discriminant model for S0, S1, S2, S3 and S4 was 83.3%, 84.2%, 70.0%, 50.0% and 88.2%, respectively. In addition, 73.3% of cross-validated rats were accurately classified. Grouping S0 as no fibrosis, S1 as mild fibrosis, S2 with S3 as moderate to severe fibrosis and S4 as early cirrhosis increased the accuracy of the discriminant model for these four groups (respectively, 91.7%, 84.2%, 69.0% and 88.2%) and allowed for 78.9% of cross-validated rats to be correctly identified. Ultrasonography combined with texture analysis was a novel and accurate method to diagnose liver fibrosis in a rat model; further studies may provide insights into its applicability for quantitating liver fibrosis in other animal models or in clinic.

Objective:To investigate the effect of flipped classroom model in the theory teaching of psychiatry for medical undergraduates.Methods:A total of 121 students from grade 2014 were randomly divided into observation group and control group. The observation group was given flipped classroom teaching and the control group was given traditional teaching. In order to evaluate the teaching effect of flipped classroom, the students in the observation group were evaluated by comparing the test scores of the two groups in class and using the self-made questionnaire. SPSS 18.0 was used to conduct t-test. Results:The results showed that the average score of the observation group was significantly higher than that of the control group ( P < 0.05). The results of teaching effect showed that there were 60 students in the observation group, among which 96.7% (58 students) believed that flipped classroom teaching was beneficial to promoting pre-class preview, improving teamwork ability, autonomous learning ability and teacher-student communication; 95.0% (57 students) thought they were satisfied with flipped classroom teaching, which was conducive to linking theory with practice; 93.3% (56 students) thought that they could arouse their interest in learning, improve their attention, and improve their ability to analyze and solve problems; 90.0% (54 students) thought flipped classroom was superior to traditional classroom and helpful to their future study; 86.7% (52 students) did not think their study burden was increased. Conclusion:The flipped classroom model can stimulate students' interest and attention, and promote the combination of independent learning and interactive learning, which has a better effect than the traditional teaching model in the theory teaching of psychiatry and is easily accepted by students. Therefore, it holds promise for application.

Non-small cell lung cancer (NSCLC) accounts for 80%-85% of all lung malignancies and good diagnosis and prognosis of NSCLC are critical to the increase of its survival rate. Tumor-associated macrophages (TAM) abundantly present in numerous cancer types, and the role of TAMs in tumor biology and their prognostic value in cancer become major topics of interest. After various stimulations in the tumor microenvironment, TAMs develop into a M1 (tumor-inhibitory) phenotype or M2 (tumor-promoting) phenotype. Recent studies show that traditional Chinese medicine (TCM) monomers have markedly inhibitory actions for NSCLC through M1/M2 modulation. Due to the TCM monomers mainly covered five categories, i.e. terpenoids, flavonoids, polysaccharides, natural polyphenols, and alkaloids. Thus, we will discuss the regulation of TCM monomers on TAM involve in these five parts in this review. In addition, the potential role of TAMs as therapeutic targets will be discussed.

Objective:To investigate the vaccination status, characteristics and prognosis of patients suffering from a combination of COVID-19 and chronic lymphocytic anemia (CLL) in China.Methods:Clinical data of 328 patients with chronic lymphocytic leukemia (CLL) who were first diagnosed with COVID-19 and treated in the Department of Hematology of Jiangsu Provincial People’s Hospital between November 2022 and February 2023 were retrospectively analyzed. Univariate and multivariate analysis of data of patients with severe/critical COVID-19 were conducted by applying the binary logistic regression model.Results:The median age of the CLL patients was 60 (24-87) years. 23.5% (77/328) of these patients suffered from severe/critical COVID-19 infection. Univariate analysis of the data demonstrated that a combination of factors including age >67 years ( OR=2.15, 95% CI 1.24- 3.73, P=0.006), diabetes ( OR=2.09, 95% CI 1.05-4.20, P=0.037), chronic hepatitis B ( OR=2.91, 95% CI 1.30-6.51, P=0.010), CLL progressive ( OR=3.79, 95% CI 1.57-9.15, P=0.003) and CD20 antibody-based treatments within three months prior to the COVID-19 infection ( OR=2.79, 95% CI 1.35-5.77, P=0.006) were the risk factors for severe/critical COVID-19. According to the multivariate analysis, CLL progressive ( OR=2.98, 95% CI 1.10-8.10, P=0.033) was an independent risk factor for severe/critical COVID-19 and administration of the BTK (Bruton tyrosine kinase) inhibitor monotherapy might exert a protective effect and influence a positive outcome of the COVID-19 infection ( OR=0.38, 95% CI 0.16-0.90, P=0.028). Among the 242 patients who were followed up until October 2023, 9.1% (22/242) had multiple subsequent COVID-19 infections (≥3), and 2.1% (5/242) had persistent COVID-19 infections (patients with persistent positive test for the SARS-CoV-2 antigen testing until missing follow-up for any reason). The peak value of the anti-SARS-CoV-2-IgG titres was observed between three and four months post symptom onset (median: 3.511 S/CO vs 1.047 S/CO, P<0.05). The levels of immunoglobulin A gradually decreased following infection with COVID-19, and its trough levels were attained between two to four weeks post infection (median: 0.30 g/L vs 0.74 g/L, P<0.05). According to this study the mortality of patients suffering from a combination of COVID-19 infection and CLL was 2.7% (9/328), and the main reason for their death was respiratory failure and heart failure. Conclusions:A low rate of COVID-19 vaccination and a high rate of severe/critical COVID-19 infection was observed in the CLL patients. CLL progressive was associated with severe/critical COVID-19. Anti-CD20-based treatments received within the past three months might be a risk factor for exacerbation of COVID-19 infection, whereas a monotherapy with BTK inhibitors exert a protective effect and improve outcome of COVID-19 infection.

OBJECTIVE:
To evaluate the clinical features of preterm infants with a birth weight less than 1 500 g undergoing different intensities of resuscitation.
METHODS:
A retrospective analysis was performed for the preterm infants with a birth weight less than 1 500 g and a gestational age less than 32 weeks who were treated in the neonatal intensive care unit of 20 hospitals in Jiangsu, China from January 2018 to December 2019. According to the intensity of resuscitation in the delivery room, the infants were divided into three groups:non-tracheal intubation (
RESULTS:
Compared with the non-tracheal intubation group, the tracheal intubation and ECPR groups had significantly lower rates of cesarean section and use of antenatal corticosteroid (
CONCLUSIONS
For preterm infants with a birth weight less than 1 500 g, the higher intensity of resuscitation in the delivery room is related to lower rate of antenatal corticosteroid therapy, lower gestational age, and lower birth weight. The infants undergoing tracheal intubation or ECRP in the delivery room have an increased incidence rate of adverse clinical outcomes. This suggests that it is important to improve the quality of perinatal management and delivery room resuscitation to improve the prognosis of the infants.

With continuous discovery of tumor immune targets and continuous changes in antibody research and development technology, antibody drugs are becoming more and more widely used in clinical practice. However, some targets are not only expressed on tumor cells, but also on red blood cells. Therefore, the clinical application of antibodies against the corresponding targets may interfere with the detection of blood transfusion compatibility, resulting in difficulty in blood matching or delay of blood transfusion. This consensus summarizes the current solutions for the interference of CD38 monoclonal antibody (CD38 mAb) in transfusion compatibility testing. After analyzing the advantages and disadvantages of different methods, polybrene and sulfhydryl reducing agents [dithiothreitol (DTT) or 2-mercaptoethanol (2-Me)], as a solution for CD38 mAb interference in blood compatibility testing, are recommended for Chinese patients, so as to eliminate blood transfusion interference produce by CD38 mAb and further provide a pre-transfusion workflow for clinicians and technicians in Department of Blood Transfusion.
