Background Vascular endothelial damage associated with endothelial progenitor cell dysfunction is considered as an initiating step of hypertension and target organ damage, in which oxidative stress plays a key role. High-intensity intermittent exercise is an effective prevention and treatment method of various chronic diseases; however, little attention has been paid to its effects and mechanisms on endothelial progenitor cells. Objective To observe the effect of high-intensity intermittent exercise on the function of endothelial progenitor cells in patients with hypertension and explore the mechanism of oxidative stress. Methods A total of 60 patients with essential hypertension were randomly divided into a control group and an exercise group. The control group received conventional drug treatment (including diuretics, calcium blockers, and beta-blockers), and the exercise group performed high-intensity intermittent exercise for 8 weeks (3 times·week−1) in addition to the treatment plan of the control group. Before and after intervention, brachial artery flow-mediated vasodilation (FMD) was used to evaluate vascular endothelial function; venous blood was sampled to perfrom circulating endothelial progenitor cell counts; endothelial progenitor cells were cultured in vitro, and the modified Boyden chamber assay and Matrigel lumen formation assay were used to detect their migration and tube formation ability, superoxide fluorescent anion probe method to detect reactive oxygen species levels, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining method to detect cell apoptosis, Western blotting to determine protein expression of reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 2, NADPH oxidase 4, and superoxide dismutase. Results Four patients (13.3%) in the control group and 2 patients (6.7%) in the exercise group dropped out; the completion rate of the exercise group's training plan was 94.9%. Compared with the before-intervention indicators, blood pressure decreased, brachial artery FMD increased, number of circulating endothelial progenitor cells increased, their migration and tube formation ability were enhanced, reactive oxygen species levels and cell apoptosis rate were reduced, NADPH oxidase 2 and NADPH oxidase 4 protein expressions were down-regulated, and superoxide dismutase protein expression was up-regulated in the after-intervention exercise group, and the differences were all statistically significant (P < 0.05). There was no significant difference in the above indicators in the control group between before and after intervention (P > 0.05). Conclusion High-intensity intermittent exercise regulates oxidative stress mediated by NADPH oxidase, improves endothelial progenitor cell function, and restores vascular endothelial disorders in patients with essential hypertension.

【Objective】 To study the molecular mechanism of 95 samples of serological ABO subtypes. 【Methods】 A total of 95 samples with discrepancy between forward and reverse blood grouping were subjected to serological confirmation, and genotyped by polymerase chain reaction with sequence-specific primers (PCR-SSP). For those subtype alleles could not be detected by PCR-SSP, ABO gene exon 1-7 sequencing and gene single strand sequencing were performed successively to determine the mutation site and the gene location. 【Results】 A total of 34 ABO alleles were detected in 95 samples. Five common ABO alleles (ABO*A1.01, ABO*A1.02, ABO*B.01, ABO*O.01.01 and ABO*O.01.02) and 29 rare ABO alleles were identified, including 16 named alleles by ISBT (ABO*A2.01, ABO*A2.05, ABO*A2.13, ABO*A3.07, ABO*AW.37, ABO*AEL.05, ABO*B3.01, ABO*B3.05, ABO*BW.03, ABO*BW.07, ABO*BW.27, ABO*BEL.03, ABO*cisAB.01, ABO*cisAB.05, ABO*BA.02, ABO*BA.04) and 5 named alleles by dbRBC(A223, B309, Bw37, Bel09, Bw40)and eight unnamed alleles [ABO*B.01+ 978C>A, ABO*A1.02+ 248A>T, ABO*B.01+ 125dupT, ABO*B.01+ (98+ 1G>A), ABO*A1.02/ABO*B.01+ 1A>G, ABO*A1.02/ABO*O.01.01+ 28G>T, ABO*A1.02/ABO*B.01+ 538C>T, ABO*A1.02/ABO*O.01.01+ 797insT] .The last four samples could not be verified by single strand because of insufficient samples. In 95 samples, 76 samples (21 named alleles of ISBT and dbRBC) were identified by PCR-SSP, and the remaining 19 samples were identified by exon 1-7 sequencing of ABO gene, of which 8 were identified as unnamed alleles, and the remaining 11 samples were not identified as subtype alleles. 【Conclusion】 The molecular genetic mechanism of 95 serological ABO subtypes was revealed, and 8 rare novel alleles were identified. The detection of ambiguous blood groups is influenced by factors such as patient pathology and physiology, therefore the combination of serological testing and genetic testing is suggested for the identification of ABO subtype.

Objective:To explore the influence of pancreatic stents of different lengths on the incidence of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP).Methods:Data of 299 patients with biliary tract diseases who received endoscopic retrograde cholangiopancreatography (ERCP) and 5 Fr prophylactic pancreatic stents placement at the First Affiliated Hospital of Air Force Medical University from January 2013 to January 2022 were retrospectively analyzed. Patients were divided into the short-stent group (<5 cm, n=163) and the long-stent group (>5 cm, n=136). Baseline data, intraoperative procedures, and postoperative outcomes were compared between the two groups and propensity score matching (PSM) was used for complementary analysis. The primary endpoint was the incidence of PEP. The risk factors for PEP in patients with prophylactic pancreatic stents placement was explored by logistic regression analysis . Results:The overall PEP incidence was 11.0% (33/299). There was no significant difference in the PEP incidence [11.7% (19/163) VS 10.3% (14/136), χ 2=0.140, P=0.708], moderate-to-severe PEP incidence [1.8% (3/163) VS 2.2% (3/136), χ 2=0.000, P=1.000], or spontaneous stent dislodgement rate within two weeks [81.7% (103/126) VS 78.4% (87/111), χ 2=0.421, P=0.516] between the two groups. After PSM, 123 patients were included in each group, and the overall PEP incidence was 8.9% (22/246). There was no significant difference in PEP incidence [8.9% (11/123) VS 8.9% (11/123), χ 2=0.000, P=1.000], moderate-to-severe PEP incidence [0.8% (1/123) VS 1.6% (2/123), χ 2=0.000, P=1.000], or spontaneous stent dislodgement rate within two weeks [80.6% (75/93) VS 78.6% (77/98), χ 2=0.126, P=0.722] between the two groups. Logistic regression analysis showed that normal liver function ( OR=2.36, 95% CI:1.01-5.51, P=0.046) and failed bile duct cannulation ( OR=7.51, 95% CI:2.18-25.96, P=0.001) were independent risk factors for PEP in patients with biliary tract diseases who received prophylactic pancreatic stents placement. Conclusion:Longer 5 Fr pancreatic stents (>5 cm) do not further reduce the overall risk of PEP or moderate-to-severe PEP compared with 5Fr-5 cm stent. Normal liver function and failure of bile duct intubation were independent risk factors for PEP after prophylactic pancreatic stent placement in patients with biliary diseases.
