This study aimed to examine the influence of the Neuregulin-1 (NRG1)/ERBB4 signaling pathway on the function of human pulmonary artery endothelial cells (HPAECs) and investigate the underlying mechanisms. Enzyme-linked immunosorbent assay indicated that ERBB4 levels in the serum of patients with pulmonary embolism (PE) were significantly higher than those of healthy controls ( < 0.05).

However, the association between per- and polyfluoroalkyl substance (PFAS) exposure and BAs in children is scarce. To address this need, we selected 252 children from the Maoming Birth Cohort and measured 32 PFAS, encompassing short- and long-chain perfluorocarboxylic acids (PFCAs) and perfluorosulfonic acids (PFSAs) in the cord blood.

Objective: To evaluate the expression level of melatonin and its effects on immune function in aplastic anemia (AA) patients.
Methods: The enzyme-linked immunosorbent assay (ELISA) was used to detect the plasma levels of melatonin in AA patients, and the correlation between melatonin levels and laboratory indexs was analyzed. The activation, proliferation, and apoptosis of T cells from AA patients were analyzed by flow cytometry with or without melatonin .

Objective: To explore the difference of lymphocyte subsets in peripheral blood (PB) between aplastic anemia (AA) and hypoplastic myelodysplastic syndrome (hypo-MDS) patients, meanwhile to compare the clinical parameters obtained from PB and bone marrow (BM).
Methods: The lymphocyte subsets in hypo-MDS (=25) and AA (=33) patients were investigated by flow cytometry. Meanwhile, the differences in PB cell counts, biochemical indicators, BM cell counts and abnormal chromosomes between the two groups were analyzed.
Background: High levels of thymidylate synthase (TS) and dihydrofolate reductase (DHFR) expression in tumour tissues are an indicator of ineffective responses to pemetrexed-based chemotherapy in various tumours, including non-small cell lung cancer (NSCLC). However, tumour tissues are highly heterogeneous, so a single biopsy may not reflect genetic alterations during disease progression. This study investigated the potential use of plasma TS and DHFR mRNA levels as biomarkers for predicting sensitivity to pemetrexed-based chemotherapy.

Based on theoretical analysis, we conclude that carbon taxes could stimulate innovation and green transition as well as subsidies when technology is mature. On the other hand, the effectiveness of carbon taxes decreases with immature technology.

Objective: To detect the expression of miRNA in de novo and complete response SAA patients and predict the targets of the miRNAs.
Methods: The expression profiles of miRNA from bone marrow mononuclear cells of the SAA patients with de novo and CR were detected by miRNA microarray.
Results: Totally 35 up-regulated and 37 down-regulated miRNA were identified in CR SAA patients in comparison with de novo SAA patients.

Objective: To explore the clinical characteristic, therapeutic efficacy and prognosis of patients with hepatitis-associated aplasitc anemia (HAAA).
Methods: the clinical data and labrotatory examination results of 30 cases of HAAA were analyzed retrospectively, the 6-month response ratio and overall survival (OS) were assessed.
Results: HAAA most commonly occured in males, with the occurence rate of males and females was 4:1, the median onset age was 16 (4-43) years old, HAAA oriented focus on sever aplastic anemia (SAA)(4 cases,13%) and very sever aplastic anemia (VSAA)(22 cases,73%).

Objective: To investigate the clinical characteristics and gene mutations of patients with Gilbert syndrome complicated with myeloproliferative neoplasms (MPN).
Methods: Peripheral blood samples from 1 patient with Gilbert syndrome complicated with MPN and his son were collected to analyse all exon mutations of UGT1A1 gene.
Results: The patient with leukocytosis, thrombocythemia, mild anemia and positive JAK2/V617F mutation was initially diagnosed as MPN.
Background: Whether or not uniportal video-assisted thoracoscopic surgery (VATS) is beneficial for spontaneous pneumothorax remains inconclusive. This meta-analysis aimed to summarize the available evidence to assess the feasibility and advantages of uniportal VATS for the treatment of spontaneous pneumothorax compared with three-port VATS.
Methods: Eligible publications were identified by searching the Cochrane Library, PubMed, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data databases and CQVIP.

Objective: To investigate the abnormalities of iron metabolism, the prevalence and risk factors of iron overload and clinical characteristics of patients with aplastic anemia (AA).
Methods: A cross-sectional study was conducted on 520 newly diagnosed AA patients.
Results: Iron overload was observed in 66(13%) of 520 AA patients,in which a higher prevalence of iron overload was seen not only in patients with infections(19/86, 22%)than those without infections (47/434, 11%, P<0.

Objective: To analyze the clinical characteristics and risk factors on responses and survival of myelodysplastic syndromes (MDS) patients with paroxysmal nocturnal hemoglobinuria (PNH) clones.
Methods: The clinical data of 31 MDS cases with PNH clones from October 2004 to June 2012 were retrospectively analyzed to reveal the influence of PNH clone size on responses and survival.
Results: ①The chromosome karyotypes were analyzed in all patients, 23 patients with normal karyotype, 7 patients with abnormal karyotype [including 3 patients with +8, 2 -Y, 1 del(7q) and 1 Xp+] and 1 patient with no mitosis.
Objective: To assess the short term curative efficacy and long-term survival outcomes of severe aplastic anemia patients following antithymocyte globulin/lymphoglobulin (ATG/ALG) with or without cyclosporine (CsA).
Methods: A total of 345 cases hospitalized in our hospital between December 1982 and June 2011 were enrolled into this study. We assessed the response rates 3 and 6 months after ATG/ALG, and estimated the overall survival (OS) by Kaplan-Meier method for this cohort of patients.

Objective: To explore the clinical significance of genetic detection and changes of red cell enzyme activities of pyrimidine 5' nucleotidase (P5'N), pyruvate kinase (PK) and glucose-6-phosphate dehydrogenase (G-6-PD) in patients with α-thalassaemia (α-thal).
Methods: Three α-thal patients were further processed to gene detection by PCR-trans-dot blot and gap-PCR, and red cell enzymes activities by absorbance at 260 and 280 nm (A) for P5'N and fluorescence spot test for PK and G-6-PD.
Results: Red cells in 3 α-thal cases were microcytic hypochromic with obvious augmented target cells and basophilic stippling erythrocytes.
Background: The -493G/T polymorphism in the microsomal triglyceride transfer protein (MTP) gene is associated with lower serum low-density lipoprotein cholesterol (LDL-C) and triglyceride (TG) levels and longevity in several populations, but the results are inconsistent in different racial/ethnic groups. The current study was to investigate the plausible association of MTP -493G/T polymorphism with serum lipid levels and longevity in Zhuang long-lived families residing in Bama area, a famous home of longevity in Guangxi, China.
Methods: The MTP -493G/T was genotyped by PCR-restriction fragment length polymorphism in 391 Bama Zhuang long-lived families (BLF, n = 1467, age 56.
