Objective To explore the difference of plasma pentraxin 3 (PTX3) levels in acute coronary syndrome (ACS) patients,and to evaluate the correlation between plasma PTX3 levels and ACS as well as hypersensitive C-reaction protein (hs-CRP), through detecting the plasma levels of PTX3 and serum levels of hs-CRP in ACS patients, stable angina pectoris (SAP) patients and normal controls. Methods According to coronary angiography results,78 subjects were divided into control group (n = 20), stable angina pectoris (SAP) group (n = 22), and acute coronary syndrome (ACS) group (n = 36). The plasma levels of PTX3 and serum hs-CRP as well as routine blood biochemical markers were detected on the second day after admission. SPSS10.0 was used for one-factor analysis of variance and Logistic regression analysis. Results The logarithm level of plasma PTX3 in ACS group was significantly higher than that of the other two groups (P <0.05). The difference between the SAP group and the control group was not statistically significant (P > 0.05). Logistic regression analysis revealed that the estimated value of the plasma PTX3 logarithm level was 2.32 (P < 0.05), that of the serum hs-CRP was 0.447 (P > 0.05). Conclusion The plasma PTX3 level in ACS group is significantly higher than that of the SAP group and the control group. The correlation between plasma FTX3 levels and the ACS is stronger than that of the serum hs-CRP levels.

Objective:To investigate the role of CD8 + T cells in lethal Plasmodium yoelii 17XL ( Py 17XL) infection. Methods:BALB/c mice and C57BL/6 mice were infected with Py 17XL-infected red blood cells (1×10 6 cells/0.1 ml) through intraperitoneal injection to establish the mouse models of Py 17XL infection. Parasitemia (the percentage of erythrocytes infected with Py 17XL) and the survival rates of the mice was observed dynamically. Flow cytometry was used to detect the number of effector T cells (T EFF) and central memory T cells (T CM) of CD8 + T cell subpopulations, the expression of IFN-γ and granzyme B (GB) levels, and the expression of surface chemokine receptors CXCR3, CXCR6 and CX3CR1. FTY720 blocking experiment was conducted on Py 17XL-infected C57BL/6 mice to analyze the impact of CD8 + T cell migration on Py 17XL infection. Results:The parasitemia of BALB/c mice increased rapidly 5 d after infection and reached the peak on 8 d [(79.57±3.82)%]. Besides, the parasitemia was higher in BALB/c mice than in C57BL/6 mice 5-8 d after infection ( P<0.000 1). All BALB/c mice died on 9 d. The parasitemia of C57BL/6 mice reached the peak on 14 d [(48.19±3.19)%] and then decreased to 0 on 26 d. There was statistically significant difference in the survival rate between the two groups ( P<0.000 1). Flow cytometry results showed that compared with the BALB/c mice, the absolute number of CD8 + T cells in spleen and liver tissues and the number of CD8 + T EFF and CD8 + T CM cells in spleen and lymph nodes of C57BL/6 mice increased significantly ( P<0.05). Compared with the BALB/c mice, the levels of GB, IFN-γ and chemokines expressed by CD8 + T cells in spleen and liver tissues of C57BL/6 mice increased significantly ( P<0.05). The FTY720 blocking experiment showed that the survival rate, the absolute number of CD8 + T cells in liver and spleen, and the number of CD8 + CXCR3 + T cells decreased significantly in the experimental group ( P<0.05). Conclusions:CD8 + T EFF and CD8 + T CM cells contribute to resistance against Py 17XL infection by secreting GB and IFN-γ. The chemokine receptor CXCR3 plays an important role in mediating the chemotaxis of CD8 + T cells to spleen and liver.

Objective To explore the value of the combination of serum hemoglobin A1c(HbA1c),Alarin and Ficolin-3 in predicting adverse pregnancy outcomes in patients with gestational diabetes mellitus(GDM).Methods From March 2021 to March 2023,129 GDM patients who underwent prenatal examination and hospital delivery in Yantai Yeda Hospital were collected as the GDM group,while 133 pregnant women with normal glucose tolerance test results were regarded as the control group.Fully automated glycated hemoglobin analyzer was applied to detect serum HbA1c level.Enzyme linked immunosorbent assay(ELISA)was applied to detect serum Alarin and Ficolin-3 levels.Pearson method was used to analyze the correlation between serum HbA1c,Alarin,Ficolin-3 levels and 2 hour postprandial glucose(2 h PG),fasting blood glucose(FBG)and homeostasis model assessment method for insulin resistance(HOMA-IR)in GDM patients.Logistic regression was applied to analyze the relationship between HbA1c,Alarin,Ficolin-3 levels and adverse pregnancy outcomes in GDM patients.Receiver operating characteristic(ROC)curve was plotted to analyze the value of serum HbA1c,Alarin and Ficolin-3 levels in predicting adverse pregnancy outcomes in GDM patients.Results The 2 h PG,FBG,HOMA-IR,and serum HbA1c,Alarin,and Ficolin-3 levels were significantly higher in the GDM group than those in the control group(P＜0.05).The serum levels of HbA1c,Alarin and Ficolin-3 were positively correlated with 2 h PG,FBG and HOMA-IR in GDM patients(P＜0.05).The serum HbA1c,Alarin and Ficolin-3 levels were greatly higher in GDM patients with poor blood glucose control than those in GDM patients with good blood glucose control(P＜0.05).The above levels of three indicators in GDM patients with adverse pregnancy outcomes were significantly higher than those in GDM patients without adverse pregnancy outcomes(P＜0.05).Elevated levels of HbA1c,Alarin and Ficolin-3 were independent risk factors for adverse pregnancy outcomes in GDM patients(P＜0.05).The area under the curves of HbA1c,Alarin and Ficolin-3 alone and in combination were 0.840,0.865,0.815 and 0.979,respectively in predicting adverse pregnancy outcomes in GDM patients.Conclusion The serum HbA1c,Alarin and Ficolin-3 levels are abnormally elevated in GDM patients,and the combined detection of the three can improve the value in predicting adverse pregnancy outcomes.

Objective:To develop an automated landmark location system applicable to the case of landmark missing.Methods:Four and eighty-one lateral cephalograms, which contained 240 males and 241 females, with an average age of (24.5±5.6) years, taken from January 2015 to January 2021 in the Department of Orthodontics, Capital Medical University School of Stomatology, and met the inclusion criteria were collected. Five postgraduate orthodontic students were the annotators to manually locate 61 possible landmarks in 481 lateral cephalograms. Two assistant professors in the department as reviewers performed calibration. Two professors as arbitrators, made final decision. Data sets were established (341 were used as training set, 40 as validation set, and 100 as test set). In this paper, an automatic landmarks identification and location model based on convolutional neural networks (CNN), CephaNET, was developed. The model was trained by feeding the original image into the feature extraction module and convolutional pose machine (CPM) module to locate landmarks with high accuracy using deep supervision. Training set was enhanced to 1 684 images by histogram equalization, cropping, and adjustment of brightness. The model was trained to compare the Gaussian heat maps output from the network with the set threshold to identify landmark missing cases. Test set of 100 lateral cephalograms was used to test the accuracy of the model. The evaluation criteria used were success detection rate of missing landmark, mean radial error (MRE) and success detection rate (SDR) in the range of 2.0, 2.5, 3.0, 3.5 and 4.0 mm.Results:The model identified and located 61 commonly used landmarks in 0.13 seconds on average. It had an average accuracy of 93.5% in identifying missing landmarks. The MRE of our testing set was (1.19±0.91) mm. SDR of 2.0, 2.5, 3.0, 3.5 and 4.0 mm were 85.4%, 90.2%, 93.5%, 95.4%, 97.0% respectively.Conclusions:The model proposed in this paper could adapt to the absence of landmark in lateral cephalograms and locate 61 commonly used landmarks with high accuracy to meet the requirements of different cephalometric analysis methods.
