OBJECTIVE:Circulating microRNAs have been recognized as promising biomarkers for various diseases. The present study aimed to explore the potential roles of circulating miR-149, miR-424 and miR-765 as non-invasive biomarkers for the diagnosis of coronary artery disease in middle-aged (40–60-year-old) patients.METHODS:Sixty-five stable coronary artery disease patients (49–57 years old), 30 unstable coronary artery disease patients (49–58 years old), and 32 non-coronary artery disease patients (49–-57 years old) who were matched for age, sex, smoking habits, hypertension and diabetes were enrolled in this study. Total RNA was isolated from plasma with TRIzol reagent. Circulating miRNA levels were measured by quantitative real-time polymerase chain reaction.RESULTS:Circulating miR-149 levels were decreased 4.49-fold in stable coronary artery disease patients (1.18 ± 0.84) and 5.09-fold in unstable coronary artery disease patients (1.04 ± 0.65) compared with non-coronary artery disease patients (5.30 ± 2.57) (p<0.001). Circulating miR-424 levels were reduced 3.6-fold in stable coronary artery disease patients (1.18 ± 0.60) and 5-fold in unstable coronary artery disease patients (0.86 ± 0.54) compared with non-coronary artery disease patients (4.35 ± 2.20) (p<0.001). In contrast, circulating miR-765 levels were elevated 3.98-fold in stable coronary artery disease patients (6.09 ± 2.27) and 5.33-fold in unstable coronary artery disease patients (8.17 ± 2.77) compared with non-coronary artery disease patients (1.53 ± 0.99) (p<0.001). Receiver operating characteristic curve analysis revealed that the respective areas under the curve for circulating miR-149, miR-424 and miR-765 were 0.938, 0.919 and 0.968 in stable CAD patients and 0.951, 0.960 and 0.977 in unstable coronary artery disease patients compared with non-coronary artery disease patients.CONCLUSION:Our results suggest that circulating miR-149, miR-424 and miR-765 might be novel, non-invasive biomarkers for the diagnosis of coronary artery disease in middle-aged patients. However, future prospective trials in large patient cohorts are necessary before reaching a solid conclusion. 相似文献

PurposeTumor-associated microRNAs have been detected in cancer, though whether plasma microRNA-155 (miR-155) could be a potential biomarker for laryngeal squamous cell carcinoma (LSCC) prognosis is unclear. We aimed to determine how miR-155 can be used to predict the clinical characteristics of patients with LSCC and correctly diagnose them.ResultsA total of 280 LSCC patients and 560 age- and sex-matched controls were included in the study. The miR-155 level was more up-regulated in LSCC tissue than in the non-tumor tissues (13.6±2.4 vs. 3.1±0.80, p<0.001). Additionally, a significantly higher miR-155 level in plasma samples from LSCC patients than in those of the controls (8.9±1.25 vs. 1.8±0.8, p<0.001) was reported. Tissue miR-155 showed an area under the curve (AUC) of 0.933, with a sensitivity of 82.6% and a specificity of 89.2%. The AUC for plasma miR-155 was 0.757, with a sensitivity of 58.4% and a specificity of 69.5%. When early LSCC in TNM I stage was considered, tissue miR-155 showed an area under the curve of 0.804, with a sensitivity of 85.2% and a specificity of 87.3%.ConclusionThe expression of tissue and plasma miR-155 were significantly up-regulated in patients with LSCC. Our work will serve as a basis for further investigation, preferably large-scale validation in clinical trials. 相似文献

Objectives: Activation of hepatic stellate cells (HSCs) into collagen producing myofibroblasts is critical for pathogenesis of liver fibrosis. Transforming growth factor-β1 (TGF-β1) is one of the main profibrogenic mediators for HSC transdifferentiation. Recent studies have shown effect of microRNAs (miRNAs) on regulating TGF-β1-induced HSC activation during liver fibrosis. Here, we aimed to explore the roles of miR-144 and miR-200c in human liver fibrosis. Methods: Expression of TGF-β1 was detected in 42 fibrotic and 18 normal human liver tissues by quantitative real time polymerase chain reaction (qRT-PCR) and immunohistochemistry, and its correlation with α-smooth muscle actin (α-SMA) was calculated. miR-144 and miR-200c expression level in fibrotic liver tissues were also detected by qRT-PCR. The correlation of TGF-β1 expression with miR-200c and miR-144 in the fibrotic liver was analyzed. Results: The results showed that TGF-β1 expression was much higher in fibrotic liver than that in normal liver tissues (P<0.05). TGF-β1 protein high expressing liver fibrosis showed α-SMA positive cells in the liver parenchyma indicating activated HSCs. Expression of TGF-β1 in fibrotic liver was significantly correlated with α-SMA expression (R=0.633, P<0.001). Furthermore, miR-144 was less expressed in liver fibrosis (P<0.05) and was significantly correlated with expression of TGF-β1 in fibrotic liver tissues (R=-0.442, P<0.01). However, miR-200c did not show significant difference between normal and fibrotic liver (P=0.48) and correlation with TGF-β1 expression (R=0.106, P=0.51). Conclusion: All the results indicate that miR-144 can be a novel regulator of TGF-β1-induced HSC activation during liver fibrosis. 相似文献

Background/Aims
Cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) are up-regulated in hepatocellular carcinoma (HCC). To investigate the levels of COX-2 and VEGF expression in chronic hepatitis (CH), cirrhosis, and HCC.Methods
The immunohistochemical expressions of COX-2 and VEGF were evaluated in tissues from patients with CH (n=95), cirrhosis (n=38), low-grade HCC (LG-HCC; n=6), and high-grade HCC (HG-HCC; n=29).Results
The COX-2 expression scores in CH, cirrhosis, LG-HCC, and HG-HCC were 3.3±1.9 (mean±SD), 4.2±1.7, 5.5±1.0, and 3.4±2.4, respectively (CH vs. cirrhosis, P=0.016; CH vs. LG-HCC, P=0.008; LG-HCC vs. HG-HCC, P=0.004), and the corresponding VEGF expression scores were 0.9±0.8, 1.5±0.7, 1.8±0.9, and 1.6±1.1 (CH vs. cirrhosis, P<0.001; CH vs. LG-HCC, P=0.011; LG-HCC vs. HG-HCC, P=0.075). Both factors were correlated with the fibrosis stage in CH and cirrhosis (COX-2: r=0.427, P<0.001; VEGF: r=0.491, P<0.001). There was a significant correlation between COX-2 and VEGF in all of the tissue samples (r=0.648, P<0.001), and between high COX-2 and VEGF expression scores and survival (COX-2: P=0.001; VEGF: P<0.001).Conclusions
The expressions of both COX-2 and VEGF are significantly higher in cirrhosis and LG-HCC than in CH. High COX-2 and high VEGF expressions are associated with a high survival rate. 相似文献7.

IntroductionWhile vitamin deficiency after bariatric surgery has been repeatedly described, few studies have focused on adequate micronutrient status. In this study, we examine the prevalence of vitamin and micronutrient deficiency for the first 3 years after surgery.MethodsOut of 1,216 patients undergoing surgery, 485 who underwent postoperative follow-up in an outpatient clinic between 2010 and 2019 were included in this evaluation (76.9% women, mean age 42 ± 12 years, mean BMI: year 1, 33.9 ± 19.2; year 2, 29.7 ± 8.7; year 3, 26.2 ± 4.0). Weight and cardiovascular risk factors as well as ferritin, vitamin B12, folic acid, 25-OH-vitamin D, vitamin A, vitamin E, zinc, copper, and selenium were evaluated. Deficits were defined as follows: ferritin <15 µg/L, vitamin B12 <197 pg/mL, folic acid <4.4 ng/mL, 25-OH-vitamin D <75 nmol/L, vitamin A <1.05 µmol/L, vitamin E <12 µmol/L, zinc <0.54 mg/L, copper <0.81 mg/L, and selenium <50 µg/L. All patients underwent dietary counselling and substitution of the respective deficits as appropriate.ResultsOne year after bariatric surgery, 485 patients completed follow-up. This number decreased to 114 patients in year 2, and 80 patients in year 3. Overall, 42.7% (n = 207) underwent sleeve gastrectomy, 43.7% (n = 211) Roux-en-Y-gastric bypass, and 13.9% (n = 67) gastric banding. The following deficits were found (year 1/2/3): ferritin, 21.6/35.0/32.5%; vitamin B12, 14.3/1.8/6.3%; folic acid, 29.7/21.6/15.3%; 25-OH-vitamin D, 70.8/67.0/57.4%; vitamin A, 13.2/8.9/12.8%; vitamin E, 0%; zinc, 1.7/0/1.5%; copper, 10.4/12.2/11.9%; selenium, 11.1/4.3/0%.ConclusionAs seen in other studies, the follow-up frequency decreased over the years. Despite intensive substitution, the extent of some deficiencies increased or did not improve. These results suggest reinforcing measures to motivate patients for regular follow-up visits, considering closer monitoring schedules, and improving supplementation strategies. 相似文献

BackgroundTriptorelin depot is largely used to treat central precocious puberty (CPP) in children, and a 3-month depot has been introduced. However, data about the 3-month gonadotropin-releasing hormone use for treatment of CPP in Korean girls are not available. This study was conducted to compare the efficacy of a triptorelin 11.25 mg 3-month depot with that of a 3.75 mg 1-month depot in suppressing pubertal development for the treatment of CPP.MethodsA retrospective study, including 106 girls with CPP treated with triptorelin, was conducted. Fifty patients were treated with a triptorelin 3-month depot, and 56 were treated with a triptorelin 1-month depot. Serum luteinizing hormone (LH), follicle-stimulating hormone, and estradiol levels were analysed every 6 months after the visit. The height and bone age of each patient was evaluated at the beginning of treatment, after 6 months, and one year after therapy.ResultsThe baseline characteristics of the girls treated with a 3-month depot were similar to those of the girls treated with a 1-month depot. A suppressed levels of LH to the triptorelin injection (serum LH < 2.5 IU/L) at 6 months was seen in 90.0% and 98.2% of the girls treated with the 3-month and 1-month depots, respectively (P = 0.160). After 1 year of treatment, a suppressed levels of LH was seen in 93.5% and 100% of the girls treated with the 3-month and 1-month depots, respectively (P = 0.226). Height velocity showed no significant difference between the two groups. Degree of bone age advancement decreased from 1.22 ± 0.07 and 1.22 ± 0.08 years at baseline (P = 0.914) to 1.16 ± 0.07 and 1.17 ± 0.08 in the girls treated with the 3-month and 1-month depots after 1 year, respectively (P = 0.481).ConclusionThis study showed that the efficacy of long-acting triptorelin 3-month was comparable to 1-month depot regarding hormonal suppression and inhibition of bone maturation. The triptorelin 11.25 mg 3-month depot is an effective treatment for girls with CPP. 相似文献

IntroductionThe current study was designed to analyze whether polymorphisms of miR-146a and miR-155 are related to Behçet’s disease (BD) in the Egyptian population.Material and methodsA total of 96 unrelated BD patients and 100 healthy subjects were genotyped for miR-146a (rs2910164) and miR-155 (rs767649) using real-time polymerase chain reaction.ResultsThe results showed significant elevation in the frequency of rs2910164 GG and CC genotypes in BD patients compared with controls (adjusted OR = 22.156, 95% CI: 4.728–103.818; p < 0.001 and adjusted OR = 40.358, 95% CI: 8.928–182.440; p < 0.001, respectively). Also, the rs2910164 G allele conferred a higher risk of developing BD (adjusted OR = 3.665, 95% CI: 2.013–6.671; p < 0.001). MiR-146a (rs2910164) polymorphism was a risk factor for susceptibility to BD in dominant, recessive and additive models of inheritance (all p < 0.001), while the miR-155 (rs767649) polymorphism was a risk factor in the recessive model only (p = 0.021). GG and CG genotypes of rs2910164 were associated with higher Behcet’s disease current activity index (BDCAI) and ocular involvement compared with CC genotype (p = 0.005 and p = 0.004, respectively). Genotype AT of rs767649 was related to higher BDCAI (p = 0.026) compared with TT and AA genotypes.ConclusionsmiR-146a (rs2910164) and miR-155 (rs767649) are likely to play an important role in the Egyptian population in development of BD and also influence disease severity. 相似文献

IntroductionData from randomized controlled trials show that liraglutide 3.0 mg, in combination with diet and exercise, is associated with greater weight loss than diet and exercise alone in patients with obesity. In practice, the utilization of weight loss drugs is influenced by various factors, including the cost of treatment. We conducted a retrospective, observational study to assess the effectiveness of liraglutide 3.0 mg and patients'' persistence on treatment, in a real-world setting.MethodsData were extracted from de-identified electronic medical records from an obesity management clinic in Switzerland. Changes in body weight and blood pressure were evaluated in the full cohort (N = 277, 19% of whom had undergone bariatric surgery) and subgroups who were persistent on liraglutide 3.0 mg for at least 4 months (n = 236), 7 months (n = 159), or 12 months (n = 71).ResultsMedian persistence on liraglutide was 6.8 months. Median maximum dose received was 1.5 mg, and 13.7% of patients reached the maintenance dose of 3.0 mg. Mean 7-month weight change from baseline in the full cohort was −4.1 kg (95% confidence interval: −5.0, −3.2; p < 0.001; −4.2%). Weight change was −4.4 kg (−4.7%) in the ≥4-month persistence subgroup at 4 months, −5.1 kg (−5.3%) in the ≥7-month persistence subgroup at 7 months, and −7.5 kg (−7.1%) in the ≥12-month persistence subgroup at 12 months (all p < 0.001). In the full cohort, 40% and 14% of patients lost ≥5% and >10% of body weight at 7 months, respectively. Weight loss did not differ significantly according to history of bariatric surgery (p = 0.94). Diastolic blood pressure decreased (from 87.0 to 83.9 mm Hg at 7 months; p = 0.018), with no significant changes in systolic blood pressure. Approximately two-thirds of patients did not have health insurance that could cover the cost of liraglutide.ConclusionIn a real-world setting with low insurance coverage and with most patients not reaching the recommended maintenance dose of 3.0 mg, the use of liraglutide, in combination with diet and exercise, was associated with clinically meaningful weight loss. 相似文献

IntroductionDespite the abundance of data addressing the influence of patient''s age on surgery-related complications, its impact on cardiometabolic outcomes following bariatric surgery has been overlooked.MethodsRetrospective unicentric study of 1,728 obese patients who underwent bariatric surgery between January 2010 and June 2015. Patients were divided in 3 age groups, according to their age at surgery: ˂40 (n = 751), 40–59 (n = 879), and ≥60 years (n = 98). Parameters with cardiometabolic impact, such as body anthropometric measures, lipid profile, and glycemic status, before and 24 months after surgery, were compared between these groups. A multiple linear regression was performed, adjusting differences between groups for sex, surgery type, and body mass index variation.ResultsThe group ˂40 years presented more weight loss (−35.4 ± 9.0 kg, p ˂ 0.001), greater BMI reduction (−15.8 ± 6.1 kg/m<sup>2</sup>, p ˂ 0.001), and larger changes in waist (−34 ± 13.8 cm, p ˂ 0.001) and hip circumferences (−28.7 ± 11.9 cm, p ˂ 0.05). The group of ≥60 years presented the heaviest reduction in fasting glucose (−17.7 ± 32.8 mg/dL, p ˂ 0.001) and HbA1c (0.7 ± 1.0, p ˂ 0.001), and also had a tendency to have the biggest changes in systolic blood pressure (−14.7 ± 18.7 mm Hg, p = 0.071).ConclusionPatients with ≥60 years benefit the most from bariatric surgery regarding cardiometabolic parameters, presenting heavier reductions in fasting glucose, as well as HbA1c and a tendency towards a higher decrease in systolic blood pressure. No clinically significant differences in lipid profile were observed between groups. 相似文献

IntroductionWeight loss in old age increases the risk of sarcopenia caused by the age-related reduction of fat-free mass (FFM). Due to the strong correlation between FFM and resting energy expenditure (REE), the maintenance of this must also be considered. Besides, the physical function (PF) must be maintained.ObjectiveThe impact of protein intake on changes in FFM, REE, and PF during weight loss in overweight postmenopausal women was investigated.MethodsFifty-four postmenopausal women (BMI 30.9 ± 3.4; age 59 ± 7 years) were randomized into 2 groups receiving energy-restricted diets with either 0.8 g (normal protein; NP) or 1.5 g protein/kg body weight (high protein; HP) for 12 weeks, followed by a 6-month follow-up phase with an ad libitum food intake. FFM, REE, and PF (strength, endurance, and balance) were measured at baseline, after weight loss, and after follow-up.ResultsForty-six women completed the weight loss intervention and 29 were followed up. The weight loss was −4.6 ± 3.6 kg (HP) and −5.2 ± 3.4 kg (NP; both p < 0.001) and the weight regain during follow-up was 1.3 ± 2.8 kg (HP; p = 0.03) and 0.4 ± 2.5 kg (NP; p = 0.39), with no differences between groups. Similar decreases in FFM (−0.9 ± 1.1 [HP] vs. −1.0 ± 1.3 kg [NP]) and REE (−862 ± 569 [HP] vs. −1,000 ± 561 kJ [NP]; both p < 0.001) were observed in both groups. During follow-up, no changes in FFM were detected in either group, whereas in the NP group the REE increased again (+138 ± 296; p = 0.02). The main determinants of FFM loss were the energy deficit and the speed of weight loss. In the NP group, the Short Physical Performance Battery score improved with weight loss (+0.6 ± 0.8; p < 0.001) and handgrip strength decreased (−1.7 ± 3.4 kg; p < 0.001), whereas no changes were observed in the HP group.ConclusionsAn HP weight-loss diet without exercise had no impact on preservation of FFM and REE but may help to maintain muscle strength in postmenopausal women. 相似文献

Study ObjectivesInsufficient sleep is believed to promote positive energy balance (EB) and weight gain. Increasing weekend sleep duration to “recover” from weekday sleep loss is common, yet little is known regarding how weekend recovery sleep influences EB. We conducted a randomized controlled trial to assess how: (1) 2 days and 8 days of insufficient sleep and (2) ad libitum weekend recovery sleep impact EB (energy intake [EI] – energy expenditure [EE]).MethodsFollowing ten baseline days with 9 h per night sleep opportunities, participants completed one of three 10-day experimental protocols with ad libitum EI: control (9 h sleep opportunities; n = 8; 23 ± 5 years [mean ± SD]); sleep restriction (SR; 5 h sleep opportunities; n = 14; 25 ± 5 years); sleep restriction with weekend recovery sleep (SR + WR; 5 days insufficient sleep, 2 days ad libitum weekend recovery sleep, 3 days recurrent insufficient sleep; n = 14; 27 ± 4 years).ResultsTwenty-four hour EB increased (p < 0.001; main effect) by an average of 797.7 ± 96.7 (±SEM) kcal during the 10-day experimental protocol versus baseline with no significant differences between groups. Percent change from baseline in 24 h-EE was higher (p < 0.05) on day 2 of insufficient sleep (SR and SR + WR groups; 10 ± 1%) versus adequate sleep (control group; 4 ± 3%).ConclusionsIn this between-group study, the effects of adequate sleep and insufficient sleep, with or without or weekend recovery sleep, on 24 h-EB were similar. Examining EB and body weight changes using within-subject cross-over designs and “free-living” conditions outside the laboratory (e.g. sleep extension) are needed to advance our understanding of the links between insufficient sleep, weekend recovery sleep and weight-gain. 相似文献

Background and purpose: To investigate the clinical significance of microRNA (miR)-23a and miR-23b expression in human gastric cancer (GC). Methods: Quantitative RT-PCR was performed to detect the expression changes of miR-23a and miR-23b in 160 human GC tissues and paired normal mucosa. The associations between miR-23a and miR-23b expression, and the selected clinicopathological characteristics and patients’ prognosis were also evaluated. Results: MiR-23a (GC vs. Normal: 3.98 ± 1.23 vs. 2.29 ± 1.12, P < 0.001) and miR-23b (GC vs. Normal: 3.70 ± 1.24 vs. 1.58 ± 1.18, P < 0.001) expression were both increased dramatically when compared with paired normal mucosa. Notably, the expression levels of miR-23a in GC tissues were positively correlated with those of miR-23b (Spearman correlation coefficient r = 0.77, P < 0.001). Then, the coexpression of miR-23a and miR-23b (miR-23a-high/miR-23b-high) in GC tissues was significantly associated with the advanced TNM stage (P < 0.001), the presence of lymph node metastasis (P = 0.008) and the great depth of invasion (P = 0.02). Furthermore, both univariate and multivariate analyses showed that miR-23a/miR-23b co-expression was an independent predictor for unfavorable overall survival. Conclusions: These results suggest that the dysregulation of miR-23a and miR-23b may be implicated in the progression of human GC. Combined expression of miR-23a and miR-23b appears to be a valuable marker for prognosis of this disease. 相似文献

IntroductionIn patients with severe obesity, albuminuria can be improved by both conventional medical therapy and bariatric surgery. The purpose of this study was to compare the impact of weight loss achieved through conventional medical therapy or laparoscopic sleeve gastrectomy (LSG) on albuminuria in Japanese subjects with severe obesity and identify the factors involved.MethodsWe retrospectively evaluated the clinical characteristics including the urinary albumin/creatinine ratio (UACR) of 340 consecutive subjects with a body mass index ≥35 who received LSG (n = 242) or medical therapy (n = 98) between 2010 and 2018 and were followed for at least 12 months.ResultsThe baseline of the UACR was not different between the 2 groups. At the 12-month follow-up, total weight loss (TWL) and decreases in glycosylated hemoglobin (HbA1c) and log<sub>e</sub> UACR were greater in the LSG group than in the medical therapy group (body weight; −35.7 kg vs. −8.0 kg, p < 0.001, HbA1c; −1.4% vs. −0.7%, p < 0.001, log<sub>e</sub> UACR; −0.3 vs. 0.9, p < 0.001). The rate of complete remission of diabetes was significantly higher in the LSG group than in the medical therapy group. At 12 and 36 months (n = 111 in the medical therapy group, n = 56 in the LSG group at 36 months), log<sub>e</sub> UACR increased in the medical therapy group, while it remained unchanged or decreased in the LSG group. In subjects with microalbuminuria and macroalbuminuria, changes in the log<sub>e</sub> UACR correlated with percent total body weight loss (%TWL) in both groups at 12 months. Percent TWL contributed independently to the change in the log<sub>e</sub> UACR, irrespective of whether LSG was performed. In receiver-operating characteristic analysis, a weight loss of 7.8% predicted a decrease in the UACR (∆UACR <0 at 12 months).ConclusionOur analysis suggests that albuminuria may increase over time if only medical therapy is continued. To improve albuminuria, weight loss may be more important than whether LSG is performed. 相似文献

IntroductionThe aim of this study was to evaluate the benefit and tolerability of two dosages of a proprietary flaxseed mucilage (IQP-LU-104) in reducing body weight in overweight and moderately obese individuals.MethodsIn a double-blind, randomized, placebo-controlled, bi-center trial, 108 participants (body mass index [BMI] 25–<35 kg/m<sup>2</sup>) were randomly allocated to receive either IQP-LU-104 high dose (104HD), IQP-LU-104 low dose (104LD), or placebo. Participants were instructed to consume 1 sachet of the investigational product (containing IQP-LU-104 or matching placebo) before or with main meals twice daily and to follow a balanced but hypocaloric diet (20% reduction of individual''s daily energy requirements) for 12 weeks. At week 0 (baseline), and weeks 4, 8, and 12 of the intervention periods, the participants'' body weight, BMI, body fat composition, and waist and hip circumferences were measured. Blood samples were collected for safety assessment at screening visit (week −2) and at the end of the study. Adverse events were assessed by the investigators through interviewing the participants and were recorded at every visit post screening.ResultsAt the end of the 12-week study, body weight reduction was greater in the 104HD group (4.96 ± 1.89 kg, p < 0.001 vs. placebo) and 104LD group (3.70 ± 2.57 kg, p < 0.001 vs. placebo) compared to the placebo group (1.33 ± 2.05 kg). 68% and 46% of participants in the 104HD group (p < 0.001 vs. placebo) and 104LD group (p = 0.002 vs. placebo), respectively, experienced at least 5% weight loss, compared to 9% of participants in the placebo group. Significant decreases in waist and hip circumferences were observed in both the 104HD and 104LD groups compared to the placebo group (each p < 0.001). 104HD group had significantly higher reduction in body fat mass (4.25 ± 5.86 kg) than the placebo group (1.06 ± 3.20 kg) (p = 0.002). Respiratory tract infections and gastrointestinal symptoms were the main adverse events reported and none of the adverse events were related to the intake of IQP-LU-104.ConclusionResults demonstrated IQP-LU-104 is safe and efficacious in body weight reduction at both dosages in overweight and moderately obese individuals. 相似文献

Introduction
This study was conducted to determine if there was a link among heart rate at rest (rHR), muscle volume changes, and single photon emission computed tomography (SPECT) parameters after 6-month cardiac rehabilitation in patients with acute myocardial infarction (AMI).Material and methods
Twenty-nine consecutive AMI patients (mean age: 63.0 ±9.1 years) who received appropriate percutaneous coronary intervention on admission were enrolled. 99mTc-Sestamibi myocardial SPECT images were obtained at the early (30 min) and delayed (4 h) phases after tracer injection at 2 weeks (0M) and 6 months (6M) after the onset of AMI. Within a few days of SPECT, all patients underwent cardiopulmonary exercise test for evaluation of cardiac rehabilitation effects. Before the initiation of exercise test, leg muscle volume was measured. All patients were stratified into the ≥ 70 beats per minute (bpm) (n = 15) or < 70 bpm (n = 14) group based on rHR at 6M.Results
There were no significant differences in the recanalization time, peak cardiac enzyme, or initial left ventricular ejection fraction between the two groups. After the 6-month training, the muscle volume changes in the lower limbs (< 70 bpm, 0.23 ±0.22; ≥ 70 bpm, –0.07 ±0.26, p < 0.05) were significantly greater in the < 70 bpm group than the ≥ 70 bpm group. The decreased rate of rHR had a significant correlation with the improved global severity (r = 0.62, p = 0.001) and extent (r = 0.48, p = 0.017) of left ventricle evaluated by 99mTc-Sestamibi myocardial SPECT delayed phase.Conclusions
The result of this preliminary study demonstrated that improved myocardial perfusion was closely related to decreased rHR after cardiac rehabilitation. 相似文献19.
Purpose
The effect of radiofrequency catheter ablation (RFCA) on left atrial (LA) volume and function in patients with paroxysmal atrial fibrillation (PAF) has not been extensively studied. The aim of this study was to evaluate the long-term impact of RFCA on LA volume and function in patients with PAF.Materials and Methods
A total of 90 patients with drug-refractory PAF who had sinus rhythm on the initial echocardiogram were examined at baseline, 3 months and 1 year after ablation. We measured LA volume index, LA ejection fraction (LAEF; maximal-minimal LA volume/maximal LA volume), and LA active emptying fraction (LAAEF; mid-diastolic-minimal LA volume/mid-diastolic LA volume).Results
After 12±1 months, 78 patients returned, and 61 patients (78%) had sinus rhythm. After 3 months, the LA maximal volume indices decreased (from 33±13 to 28±12 mL/m2; p<0.001). But, LAEF and LAAEF also decreased (from 48±13 to 39±12; p<0.001, from 27±13 to 19±11; p<0.001). After 1 year, LA volumes, LAEF, and LAAEF remained similar at 3 months. In patients without atrial fibrillation (AF) recurrence, LAEF and LAAEF decreased after 3 months (from 50±12 to 40±11; p<0.001, from 29±13 to 22±11; p<0.001) and did not change after 1 year. However, in patients with AF recurrence, those who did not have decreased levels after 3 months had significantly decreased after 1 year (from 43±14 to 34±11; p=0.026, from 22±12 to 15±10; p=0.012).Conclusion
Successful RFCA of PAF decreased LA volume and function at 3 months. At one year, LA volume and function was remained unchanged in successfully ablated patients whereas LA function in patients with AF recurrence worsened. 相似文献20.

OBJECTIVE:Evaluate the efficiency and safety of bipolar plasma vaporization using plasma-cutting and plasma-loop electrodes for the treatment of posterior urethral stricture. Compare the outcomes following bipolar plasma vaporization with conventional cold-knife urethrotomy.METHODS:A randomized trial was performed to compare patient outcomes from the bipolar and cold-knife groups. All patients were assessed at 6 and 12 months postoperatively via urethrography and uroflowmetry. At the end of the first postoperative year, ureteroscopy was performed to evaluate the efficacy of the procedure. The mean follow-up time was 13.9 months (range: 12 to 21 months). If re-stenosis was not identified by both urethrography and ureteroscopy, the procedure was considered “successful”.RESULTS:Fifty-three male patients with posterior urethral strictures were selected and randomly divided into two groups: bipolar group (n=27) or cold-knife group (n=26). Patients in the bipolar group experienced a shorter operative time compared to the cold-knife group (23.45±7.64 hours vs 33.45±5.45 hours, respectively). The 12-month postoperative Qmax was faster in the bipolar group than in the cold-knife group (15.54±2.78 ml/sec vs 18.25±2.12 ml/sec, respectively). In the bipolar group, the recurrence-free rate was 81.5% at a mean follow-up time of 13.9 months. In the cold-knife group, the recurrence-free rate was 53.8%.CONCLUSIONS:The application of bipolar plasma-cutting and plasma-loop electrodes for the management of urethral stricture disease is a safe and reliable method that minimizes the morbidity of urethral stricture resection. The advantages include a lower recurrence rate and shorter operative time compared to the cold-knife technique. 相似文献
