Abstract Background To investigate the main environmental factors of hypertension and the relationship between hypertension and circular RNAs in peripheral blood lymphocytes. Methods This was a case–control study. A total of 681 hypertension patients and 485 subjects without hypertension were recruited between April 2017 and October 2018. All participations completed the questionnaire investigation, physical examination, and laboratory detection. Quantitative real-time polymerase chain reaction was used to analyze circRNAs (hsa_circ_0001946 and hsa_circ_0125589) in peripheral blood leukocytes in 84 hypertensives and 84 controls. Multivariate logistic regression and crossover analysis were used to analyze the interaction and association between environmental factors and circRNAs in hypertension. Results After adjusted by gender, age and marital status, overweight/obesity (odds ratio (OR) = 1.66, 95% confidence interval (CI) 1.24–2.22), abdominal obesity (OR = 2.17, 95% CI 1.54–3.04), anxiety (OR = 2.15, 95% CI 1.41–3.28), family history of hypertension (OR = 4.26, 95% CI 3.18–5.70), and higher levels of hsa_circ_0001946 (OR = 4.13, 95% CI 1.85–9.21) were risk factors for hypertension, while levels of hsa_circ_0125589 were not associated with hypertension. Crossover analysis showed that the risk of hypertension was 13.12 times higher (95% CI 3.89–44.23) in overweight subjects with high hsa_circ_0001946 levels compared with normal weight subjects with low hsa_circ_0001946 levels. Further, the risk of hypertension was 17.78 times higher (95% CI 1.88–168.61) in subjects with anxiety and high hsa_circ_0001946 levels. Conclusions Hypertension is the result of both environmental factors and genetic factors. Higher hsa_circ_0001946 levels, overweight and anxiety may increase the risk of hypertension, while hsa_circ_0125589 levels are not related to hypertension.

Abstract Infection of peripheral blood mononuclear cells (PBMNCs) has been demonstrated to be a crucial event in the vertical transmission of viruses, and it is known that hepatitis C virus (HCV) can infect PBMNCs. The relationship between vertical transmission of HCV and the presence of positive and negative strands of HCV-RNA in the PBMNCs of HCV-carrier mothers was investigated using reverse transcriptase–polymerase chain reaction (RT-PCR). During the study, 13 consecutive mothers who transmitted infection to their offspring and 53 consecutive mothers who did not were examined. The positive strand of HCV-RNA was identified in the PBMNCs of all mothers who transmitted the infection and in 13 of 53 mothers who did not (P < 10−6). The HCV-RNA−strand was found in 5 of 13 mothers who transmitted the infection, and the strand was not found in the mothers who did not transmit the infection (P = .0001). Neither maternal PBMNC infection nor HCV transmission to the offspring was significantly related to the viral genotype or to the maternal viral load. These data show that maternal PBMNC infection by HCV and viral replicative activity in PBMNCs are important factors in the transmission of HCV from mother to child. The mechanism through which HCV infection of PBMNC favors vertical transmission of the virus is still incompletely understood.

Abstract Background Pulmonary arterial hypertension (PAH) caused by congenital heart disease (CHD) is very common in clinics. Some studies have shown that PAH is related to the number of endothelial progenitor cells (EPCs), but there is no report on the relationship between PAH and the number of EPCs in children with CHD. Methods In this study, a total of 173 cases with CHD (from 0 to 6 years old) were collected. According to the mean pulmonary arterial pressure (mPAP) measured by right heart catheterization, these cases were divided into PAH groups (including high PAH group, mPAP> 25 mmHg, n = 32, and the middle PAH group, 20 mmHg ≤ mPAP≤25 mmHg, n = 30) and non-PAH group (mPAP< 20 mmHg, n = 111). Peripheral blood was taken for flow cytometry, and the number of EPCs (CD133+/KDR+ cells) was counted. The number of EPCs /μL of peripheral blood was calculated using the following formula: EPCs /μL = WBC /L × lymphocytes % × EPCs % × 10− 6. Results The median EPCs of the non-PAH group, middle PAH group and high PAH group is 1.86/μL, 1.30 /μL and 0.98/μL, respectively. The mPAP decreases steadily as the level of EPCs increases (P < 0.05). After adjustment of gender, age and BMI, the number of EPCs was significantly associated with a decreased risk of high PAH (OR = 0.37, 95% CI: 0.16–0.87, P < 0.05). However, EPCs was not significantly associated with middle PAH (P > 0.05). Conclusion The findings revealed that the EPCs and high PAH in patients with CHD correlate significantly and EPCs may become an effective treatment for PAH in patients with CHD. EPCs may be a protective factor of high PAH for children with CHD.

Abstract We planned a prospective analysis involving 3 multicentric national studies of the GIMEMA (Gruppo Italiano Malattie Ematologiche Adulto) CML Working Party (WP) to evaluate the correlation between conventional cytogenetics (CC) and FISH response in CML pts in chronic phase (CP) treated with Imatinib. Karyotype and FISH analyses were performed on bone marrow (BM) cells in 26 local laboratories and in 12 WP reference labs. Peripheral blood samples for quantitative RT-PCR were centralized in Bologna. The data are reported in Figure 1 and in Table 1. Fig 1 shows the relationship between CC and FISH (r=0.91;p=0.008). Tab 1 shows the demonstration of FISH data according to CC data and the number of metaphases available for CC. Of 217 pts in CCgR by CC and &gt; 20 metaphases studied, 81.6% were FISH negative, 15.2% showed a low rate of FISH positive cells (1–5%) and 3.2% an higher rate. Of 94 pts in CCgR by CC but with &lt; 20 metaphases studied, 71.3% were FISH negative, 21.3% showed a low rate of FISH positive cells (1–5%) and 7.4% an higher rate. Of 43 pts in PCgR by CC and FISH positive, 48.8% showed 1– 5% positive cells. Moreover, 358 samples were performed simultaneously by CC, FISH and quantitative RT-PCR: 179 (50%) samples in CCgR showed major molecular response (MMolR, defined as a BCR-ABL × 100 ratio &lt; 0.1%): 164 (91.6%) were FISH negative and 15 (8.4%) were FISH positive (1.3–10% positive cells). We conclude that interphase FISH is a very releable method of monitoring the CCgR once it has been achieved. The relationship of FISH on BM cells with molecular response is at least as good as the relationship of CC with molecular response. It remains to be shown if the same results can be obtained on peripheral blood cells, that are already widely used for molecular monitoring.

Immunoglobulin A nephropathy (IgAN) is a primary glomerulonephritis characterized by abnormal immune response-mediated deposition of polymeric IgA (pIgA) in mesangium. As a type of important immune cells, the relationship of CD3 or CD4 with the pathogenesis of IgAN remains poorly understood. In this study, 38 patients with IgAN, 7 patients with idiopathic membranous nephropathy (MN) and 46 healthy adults without history of kidney disease were enrolled. Peripheral blood was collected for further evaluation of the expressions of CD3 and CD4 and IgA by flow cytometry, quantitative polymerase chain reaction (qPCR) and Western blot. Meanwhile, the expression of IgA was detected by ELISA. The result showed that expression of CD3 T cells was down-regulated in patients with IgAN, while amounts of CD4 T cells and IgA level were significantly increased compared to normal control (P < 0.05). However, no signficant changes in CD3, CD4 T cells were found in patients with MN. Our study demonstrates that CD3 and CD4 T cells as well as IgA are involved in the pathogenesis of IgAN and these targets might be beneficial for the treatment of IgAN.
