Abstract: To evaluate the potential value of the plasma level of receptor- interacting protein kinase 3 (RIPK3), a key protein involved in the activation of necroptosis, as a biomarker for the differential diagnosis of lung cancer in patients with lung lesions detected by chest computed tomography. The subjects of this study were divided into 3 groups: lung cancer (n = 30), benign disease (n = 13), and healthy controls (n = 33). The measurement of plasma RIPK3 was performed by enzyme-linked immunosorbent assay. The plasma RIPK3 level in patients with lung cancer (1467.4 ± 347.4 pg/ml) was significantly higher than that in patients with benign disease (1219.8 ± 156.4 pg/ml) and healthy controls (746.2 ± 255.3 pg/ml). Besides, plasma RIPK3 levels that were greater than 970.06 pg/ml provided 96.7% sensitivity and 84.8% specificity for lung cancer. Our results show that plasma RIPK3 levels are higher in lung cancer patients. We suggest that plasma RIPK3 level could be used as an auxiliary tool for distinguishing lung cancer from benign lesions and healthy lungs.

Abstract: The treatment of ischemic heart disease mainly depends on the formation of blood vessels and the survival of cardiac myocytes. This paper will research the enhancement of EPC cells by mesenchymal stem cells in the treatment of ischemic heart disease. Mouse bone marrow was collected, MSCs cells were isolated and cultured. Flow cytometry was used to test the expression of CD34 and CD44. Then MSCs cells and endothelial progenitor cells co-culture 48 h, and 24 Wistar rats were randomly divided into EPCs group, EPCs MSCs + group and the control group. MSCs 2×10⁶, EPCs 2×10⁶, EPCs 2×10⁶, and PBS buffer were injected into five different regions around ischemic myocardium. The changes in cardiac function were assessed by echocardiography after 4 weeks. MSCs 2×10⁶, EPCs 2×10⁶, EPCs 2×10⁶, and PBS buffer were injected into five different regions around ischemic myocardium. The changes in cardiac function were assessed by echocardiography after 4 weeks. The rats were sacrificed, and the expression of VEGF was detected by immunohistochemistry and immunofluorescence. The surface markers CD34 and CD44 of MSCs and EPCs were differentially expressed. We successfully isolated MSCs and EPCs cells. Meanwhile, the proliferation index Ki67 was highly expressed, suggesting that MSCs could effectively promote the proliferation activity of EPCs. Echocardiography showed that after MSCs+EPCs treatment, the left ventricular ejection fraction, end-diastolic volume and cardiac volume of the rats were significantly improved, with statistically significant differences from the control group and the EPCs group (P<0.05), Meanwhile, the expression of VEGF in MSCs+EPCs group was also significantly increased (P<0.05). Mesenchymal stem cells can enhance the therapeutic effect of EPC cells in ischemic heart disease, which can promote myocardial angiogenesis, improve ventricular remodeling and cardiac function.

Abstract:  Autism Spectrum Disorders have for some time been the focus of intense interest for clinicians and researchers because of the high prevalence of the disorders among children in the community. Particular attention has been paid to the early diagnosis of the disorder and to the intensive therapeutic intervention. Currently the best prognosis for autism lays in the early diagnosis and intervention. But diagnosis of autism at an early age is challenging due to the existing phenotypic and etiological heterogeneity among ASD individuals. There are many screening scales for autism, but their specificity and sensitivity vary to varying degrees. Therefore, an efficient early diagnosis method is needed. This paper presents a review of the early detection of ASD.
