ABSTRACT

Objective@#To analyze the cumulative effect of preadolescent lifestyles on the prevalence and incidence of elevated blood pressure (EBP) in children, and to provide evidence for early hypertensive intervention.@*Methods@#In 2017, a cohort study on pubertal development was conducted in Xiamen, Fujian Province. Participants underwent a physical examination and questionnaire survey. Between 2017 and 2019, this study carried out a 2-year follow-up of 1 316 students whose complete data were obtained. Preadolescent lifestyles were assessed by referring to baseline survey results obtained in 2017, and the prevalence and incidence of EBP were determined according to blood pressure levels that were determined in 2019. The logistic regression model was used to analyze the influence of healthy lifestyles on the prevalence and incidence of EBP after adjusted for confounding factors.@*Results@#The prevalence of EBP in 2017 and 2019 was 25.0% and 23.3%, respectively, and its incidence was 18.9% after the 2-year follow-up. Children with a healthy lifestyle had a lower prevalence and incidence of EBP. The regression analysis showed that children who have more healthy lifestyle factors were at a lower risk of EBP (P<0.05). Compared with students with 0-2 healthy lifestyle factors, the OR value of EBP prevalence was 0.52 (95% CI=0.30-0.90) and the RR value of EBP incidence was 0.60(95%CI=0.29-1.22) in children with 4-5 healthy lifestyle factors. Among them, children who were overweight or obese were at a significantly lower risk of EBP prevalence (OR=0.29, 95%CI=0.10-0.81).@*Conclusion@#Preadolescent lifestyles seemed to have a cumulative effect on the occurrence of EBP. Maintaining a healthy lifestyle had a positive effect on reducing the risk of EBP, particularly in overweight and obese children, and this was due to their adoption of a comprehensive healthy lifestyle.

ABSTRACT

Objective:To explore the effect of intermittent theta-burst stimulation (iTBS) of the cerebellum on the excitability of the M1 zone in the bilateral motor cortex and the duration of any effect.Methods:Twenty healthy youths were randomly assigned to a left or a right cerebellum iTBS group, each of 10. The resting motor threshold and motor evoked potential (MEP) of the motor cortex were determined before giving 600 pulses of iTBS. Then MEP was measured at the 5th, 10th, 15th, 20th, 25th, 30th, 35th and 40th minute after the intervention ended. Any changes in MEP amplitude were also analyzed.Results:①The average MEP amplitude in the right motor cortex had increased significantly in the left cerebellum iTBS group from the 5th to the 15th minute. The increase lasted at least 10 minutes. Then it had returned to the baseline value at the 35th minute. ②The MEP amplitude in the left motor cortex decreased slightly after iTBS of the left cerebellum began, but there were no significant changes. ③The MEP amplitude in the left motor cortex had a tendency to decrease after iTBS was administered to the right cerebellum, but that change too was not significant. ④The MEP amplitude of the right motor cortex decreased significantly only for the first 30 minutes.Conclusions:iTBS of the cerebellum can increase the excitability of the contralateral motor cortex. The effect can last 25 minutes. It can also decrease the excitability of the ipsilateral motor cortex for 30 minutes.

ABSTRACT

Objective:To investigate any change in the effective connectivity between the bilateral anterior central gyruses after transcranial magnetic stimulation (TMS).Methods:Twenty-one healthy subjects were examined using resting state functional magnetic resonance imaging (rs-fMRI) before and after receiving continuous theta burst stimulation (cTBS). The brain atlas of the Institute of Automation of the Chinese Academy of Sciences was used for fine partitioning of the bilateral anterior central gyruses. Granger causality analysis was used to compare any changes in the effective connectivity between them.Results:After the cTBS inhibited the right M1 area, significant changes in effective connectivity among the sub-regions of the bilateral M1 area were observed. The effective connectivity of the right upper limb to the left upper limb and the left head to face were weakened, while that of the left upper limb to the right head, as well as of the face to the right upper limb was enhanced.Conclusion:For people whose right M1 area has been inhibited by cTBS, the effective connectivity changes in both upper limb functional areas of the M1 region reflect inter-hemispheric inhibition. Opposite changes were found in the trunk and upper limbs.

ABSTRACT

Objective:To assess the urethral mobility of normal parous women in China and explore the impacts of related risk factors on it using translabial ultrasound.Methods:Females who met the inclusion criteria in 37 tertiary hospitals from February 2017 to August 2018 were included. All women underwent standardized translabial ultrasound examination and the urethral rotation angle (URA), bladder neck position at maximum Valsalva maneuver (BNP-V) and bladder neck descent (BND) were measured. Questionnaires were used to collect basic information including age, height, weight, body mass index (BMI), past medical history, maternity history, and urinary incontinence related history. Mann-Whitney U test and multiple linear regression analysis were adopted to explore the influences of age, BMI, delivery mode and parity on normal parous women′s urethral mobility. Then, the study subjects were divided into different groups and the corresponding values of URA, BNP-V and BND were compared. Results:Compared with parous women with normal BMI and no history of vaginal delivery, those who were overweight and/or had a history of vaginal delivery were more likely to gain greater URA and BND ( P<0.05). The URA and BND were not significantly different between women with different times of cesarean sections ( P>0.05); while for women with a history of vaginal delivery, these two parameters increased with the increase of the number of transvaginal deliveries ( P<0.05). Conclusions:BMI and vaginal delivery are important risk factors for the urethral mobility of normal parous women. The urethral mobility increases with the increase of BMI and the number of vaginal deliveries.

ABSTRACT

Objective:To analyze the incidence and risk factors of non-acute symptomatic portal vein thrombosis (PVT) after endoscopic gastric variceal injection (GVI) in the treatment of liver cirrhosis with gastric variceal bleeding (GVB).Methods:66 patients with GVB who were treated with GVI for the first time from July 2017 to October 2019 in Minhang Hospital Affiliated to Fudan University were retrospectively analyzed. The data of gender, age, preoperative Child-Pugh grade, preoperative platelet count, preoperative plasma D-dimer concentration, preoperative splenic length, preoperative portal vein velocity, preoperative splenic vein velocity, preoperative portal vein diameter, preoperative splenic vein diameter, treatment times, total number of injection points, total dose of sclerosing agent and tissue adhesive agent were collected. The patients were divided into PVT group and non-PVT group according to the occurrence of non-acute symptomatic PVT within one year after GVI. Univariate analysis was performed first, and then the factors with P<0.2 were included in the binary logistic regression model to screen the risk factors of PVT after GVI. Results:There were 25 cases (37.88%) in PVT group and 41 cases (62.12%) in non-PVT group. There were significant differences in D-dimer concentration, spleen length, Child-Pugh grade and total dose of sclerosing agent between the two groups ( P<0.05). The D-dimer concentration ( OR=2.319, 95% CI:1.359-3.956), spleen length ( OR=1.044, 95% CI:1.007-1.081) and total dose of sclerosing agent ( OR=1.075, 95% CI:1.004-1.152) were independent risk factors for PVT ( P<0.05). Conclusions:Preoperative D-dimer concentration, spleen length and total dose of sclerosing agent can predict the risk of PVT after GVI. In order to reduce the risk of PVT after GVI, the dose of sclerosing agent should be reduced as much as possible.

ABSTRACT

Objective:To investigate the therapeutic effect of cardiac rehabilitation exercise on ventricular remodeling in patients with acute myocardial infarction undergoing percutaneous coronary intervention.Methods:A total of 100 patients with acute myocardial infarction undergoing percutaneous coronary intervention who received treatment in Wenzhou Central Hospital from June 2018 to June 2019 were included in this study. They were randomly divided into a rehabilitation group and a conventional treatment group ( n = 50/group). Patients in the conventional treatment group underwent conventional postoperative rehabilitation education while those in the rehabilitation group received targeted cardiac rehabilitation exercise. After surgery, all patients were followed up for 12 months. Real time three-dimensional echocardiography was used to evaluate ventricular remodeling (left ventricular ejection fraction, left ventricular end-diastolic volume , left ventricular end-systolic volume, left ventricular remodeling index) and ventricular synchrony (Tmsv-16dif, Tmsv-16sd, Tmsv16-dif%, Tmsv16-sd%) before and 3, 6 and 12 months after surgery. In addition, serum levels of ventricular remodeling indexes (fibroblast growth factor 23, PICP and PIIINP) were measured. The incidence of cardiovascular end-point events within 12 months was calculated. Results:At 3, 6 and 12 months after surgery, left ventricular ejection fraction was (51.81 ± 5.43)%, (55.88 ± 5.46)%, (55.63 ± 5.57)% in the rehabilitation group, which was significantly higher than (47.16 ± 5.38)%, (52.31 ± 5.44)%, (51.84 ± 5.59)% respectively in the conventional treatment group ( t = 4.302, 3.275, 3.396, all P < 0.05). At 3, 6 and 12 months after surgery, left ventricular end-diastolic volume was (124.65 ± 15.56) mL, (98.54 ± 14.54) mL, (99.82 ± 13.18) mL, respectively in the rehabilitation group, which was lower than (132.64 ± 16.58) mL, (112.55 ± 15.61) mL and (114.84 ± 17.35) mL, respectively in the conventional treatment group ( t = 2.485, 4.644, 4.874, all P < 0.05). At 6 and 12 months after surgery, left ventricular end-systolic volume was (52.26 ± 5.48) mL and (52.15 ± 5.32) mL respectively in the rehabilitation group, which was significantly lower than (57.92 ± 5.46) mL and (58.51 ± 5.72) mL in the conventional treatment group ( t = 5.174, 5.757, both P < 0.05). At 6 and 12 months after surgery, left ventricular remodeling index was (1.75 ± 0.42) g/mL and (1.74 ± 0.35) g/mL respectively in the rehabilitation group, which was significantly higher than (1.52 ± 0.37) g/mL and (1.50 ± 0.32) g/mL, respectively in the conventional treatment group ( t = 2.906, 3.579, both P < 0.05). At 3, 6 and 12 months after surgery, Tmsv-16dif ( t = 2.753, 4.283, 4.088, all P < 0.05), Tmsv-16sd ( t = 5.134, 4.326, 4.670, all P < 0.05), Tmsv-16dif% ( t = 7.714, 8.587, 7.800, all P < 0.05) and Tmsv16-sd% ( t = 9.004, 14.061, 10.305, all P < 0.05) respectively in the rehabilitation group, were significantly lower than those in the conventional treatment group. At 3, 6 and 12 months after surgery, fibroblast growth factor 23 ( t = 6.303, 5.053, 4.619, all P < 0.05). PICP ( t = 3.772, 2.798, 3.788, all P < 0.05) and PIIINP ( t = 3.110, 5.912, 4.294, all P < 0.05) in the rehabilitation group were significantly lower than those in the conventional treatment group. Within 12 months, the total incidence of cardiovascular end-point events in the rehabilitation group [12.00% (6/50)] was significantly lower than that in the conventional treatment [32.00% (16/50)] ( χ2 = 5.828, P < 0.05). Conclusion:Cardiac rehabilitation exercise can improve ventricular remodeling and synchrony in patients with acute myocardial infarction undergoing percutaneous coronary intervention and reduce the incidence of cardiovascular end-point events.

ABSTRACT

@#AIM: To evaluate the effect of stereoscopic 4D(S4D)technology as a visual training system in children with hyperopic amblyopia and hyperopic anisometropic amblyopia.<p>METHODS: Totally 48 patients aged 3-9 years with hyperopic amblyopia and hyperopic anisometropic amblyopia were recruited, including 18 hyperopic amblyopia(36 eyes)and 30 hyperopic anisometropic amblyopia(30 eyes). All patients excluded other eye diseases and received S4D technology training on the basis of refractive correction and reasonable covering. The initial training was mainly to improve visual acuity. Those with visual acuity above 0.6 were treated with disinhibition training and binocular visual function training. The changes of visual acuity and binocular stereopsis before and after training were compared.<p>RESULTS: The 18 patients(36 eyes)with hyperopic amblyopia were divided into mild amblyopia group(<i>n</i>=13), moderate amblyopia group(<i>n</i>=19)and severe amblyopia group(<i>n</i>=4). 30 patients(30 eyes)with hyperopic anisometropic amblyopia were divided into mild amblyopia group(<i>n</i>=5), moderate amblyopia group(<i>n</i>=13)and severe amblyopia group(<i>n</i>=12). The visual acuity was significantly improved after 60 times of treatment. After 60 times of treatment, stereopsis was significantly improved, which had nothing to do with the initial diopter(<i>P</i>>0.05), but positively correlated with the visual acuity initially and finally(<i>P</i><0.05), and positively correlated with the amount of anisometropia(<i>P</i><0.05). <p>CONCLUSION: S4D technology training combined with traditional treatment can effectively improve the visual acuity and binocular function of 3-9 years old children with anisometropic amblyopia and hyperopic anisometropic amblyopia.

ABSTRACT

The chemical constituents from the stems and leaves of Morinda citrifolia were isolated and purified by column chromatography methods with silica gel, ODS, Sephadex LH-20 and preparative high performance liquid chromatography(HPLC). The structures of the isolated compounds were identified by physicochemical properties and spectroscopic analysis, as well as comparisons with the data reported in literature. 17 compounds were isolated from the 90% ethanol extract of the stems and leaves of M. citrifolia, and were identified as 9,10-dihydroxy-4, 7-megastigmadien-3-one(1), 5,12-epoxy-6,9-hydroxy-7-megastigmen-3-one(2), fukinone(3), β-eudesmol(4), sarmentol F(5), 4, 5-dihydroblumenol A(6), 3-hydroxy-β-ionone(7), aristol-8-en-1-one(8), ergosta-7-en-3β-ol(9), ergosta-7-ene-3β,5α,6β-triol(10),(22E)-5α,8α-epidioxyergosta-6,22-dien-3β-ol(11), olivil(12), 4-epi-larreatricin(13), chushizisin Ⅰ(14), rabdosia acid A(15), glycerol monolinoleate(16) and(9Z,12Z,15Z)-2,3-dihydroxypropyl octadeca-trienoate(17). All compounds were isolated from M. citrifolia for the first time. All isolated compounds were evaluated for their anti-rheumatoid arthritis activities via examining their inhibitory activities on the proliferation of synoviocytes in vitro using MTS met-hod. Compounds 1-11 showed significant anti-rheumatoid arthritis activities, displaying the inhibitory effects on the proliferation of MH7 A synovial fibroblast cell with the IC_(50) values ranging from(38.69±0.86) to(203.45±1.03) μmol·L~(-1).

ABSTRACT

Photoperiod plays an important role in transformation from vegetative growth to reproductive growth in plants. CONSTANS (CO), as a unique gene in the photoperiod pathway, responds to changes of day length to initiate flowering in the plant. In this study, the expression level of FaCONSTANS (FaCO) gene under long-day, short-day, continuous light and continuous darkness conditions was analyzed by real-time quantitative PCR. We constructed the over-expression vector p1300-FaCO and infected into Arabidopsis thaliana by Agrobacterium-mediated method. We constructed the silencing vector p1300-FaCO-RNAi and infected into Festuca arundinacea by Agrobacterium-mediated method. The expression of FaCO gene was regulated by photoperiod. The over-expression of FaCO promoted flowering in wild type of Arabidopsis thaliana under long day condition and rescued the late flowering phenotype in co-2 mutant of Arabidopsis thaliana. Silencing FaCO gene in Festuca arundinacea by RNAi showed late-flowering phenotype or always kept in the vegetative growth stage. Our understanding the function of FaCO in flowering regulation will help further understand biological function of this gene in Festuca arundinacea.

ABSTRACT

BACKGROUND@#Epigenetics, especially DNA methylation, plays an important role in the pathogenesis of primary Sjogren syndrome (pSS). Our study aimed to reveal the role of DNA methylation in peripheral monocytes of pSS patients.@*METHODS@#A total of 11 pSS patients and five age-matched healthy controls (HCs) were included in this study. Monocytes were isolated from peripheral blood mononuclear cells using magnetic microbeads. DNA methylation profiles were generated using Human Methylation 850K BeadChips.@*RESULTS@#In monocytes from pSS patients, we identified 2819 differentially methylated positions (DMPs), comprising 1977 hypomethylated- and 842 hypermethylated-DMPs, corresponding to 1313 unique genes when compared with HCs. IFI44L, MX1, PAARP9, and IFITM1, which influence the interferon (IFN) signaling pathway, were among the genes hypomethylated in pSS. Functional analysis of genes with a minimum of two DMPs showed involvement in antigen binding, transcriptional regulation, cell adhesion, IFN-γ pathway, type I IFN pathway, antigen presentation, Epstein-Barr virus infection, human T-lymphotropic virus type 1 virus infection, and metabolic disease-related pathways. In addition, patients with higher serum IgG levels exhibited enrichment in Notch signaling and metabolic-related pathways. Upon comparing monocytes with salivary gland epithelial cells, an important overlap was observed in the cell cycle, cell senescence, and interleukin-17 signaling pathways. The differentially methylated genes were more enriched in the ribosome- and AMP-activated protein kinase signaling pathway in anti-Ro/SSA and anti-La/SSB autoantibodies double-positive patients.@*CONCLUSION@#Genome-wide DNA methylation profiling revealed significant differences in DNA methylation in monocytes isolated from patients with pSS.

ABSTRACT

INTRODUCTION@#Associations of variations in PLA2R1 and HLA-DQA1 genes with susceptibility to idiopathic membranous nephropathy (IMN) have been well documented. Association with spontaneous remission, however, is poorly defined in the Chinese Han population.@*METHODS@#A Chinese cohort of 117 IMN patients and 138 healthy controls were recruited between July 2009 and November 2019. Case-control studies for single-nucleotide polymorphisms (SNPs) within HLA-DQA1 (rs2187668) and PLA2R1 (rs35771982, rs4664308, rs3749117, rs3749119) genes were performed. The contributions of these polymorphisms to predict susceptibility, titre of autoantibodies against the M-type phospholipase A2 receptor (anti-PLA2R1), glomerular PLA2R1 expression, and spontaneous remission were analysed.@*RESULTS@#We found that variations in PLA2R1 (SNPs rs35771982, rs4664308, rs3749117) were strongly associated with IMN susceptibility, while SNP (rs2187668) within HLA-DQA1 did not increase the risk of IMN. All SNPs in PLA2R1 and HLA-DQA1 were not statistically associated with anti-PLA2R1 titre, glomerular PLA2R1 expression and spontaneous remission after Bonferroni correction (@*CONCLUSION@#This study confirms that variations in PLA2R1 (SNPs rs35771982, rs4664308, rs3749117) are risk factors for IMN. We found excellent association of serum albumin level, anti-PLA2R1 titre and glomerular PLA2R1 positivity with non-spontaneous remission in IMN.
