Background: Recent development of extracorporeal magnetic stimulation (ECMS) which uses current‐changing magnetic fields allows the induction of electrical stimulation in the desired deep tissue. Recent study showed the sacral nerve stimulation reduces corticoanal excitability that may play a functional role in anal continence mechanisms. Preliminary study shows that ECMS of sacral nerve can modify pelvic floor function and expel rectal balloon in patients with pelvic floor dyssynergia (PFD). Aims: To evaluate the effect of ECMS compared with biofeedback therapy (BF) in patients with PFD. Methods and Materials: Thirty‐eight patients who fulfilled Rome II criteria for PFD by colon transit time and anorectal function tests, were randomly treated with 8 sessions of ECMS (2/weeks; n = 19) at prone position or BF (2/weeks; n = 19) at sitting position. Stimulation parameters were set at 50–80% of maximum intensity, 10 and 50 Hz frequency, 3 s burst length with 3 and 6 s off using arm‐typed stimulator (BioCom‐1000, Mcube Co., Korea). Symptom scores for constipation with/without anorectal function test were repeatedly measured after each treatment. Response was defined as 50% or more decreased symptom score after treatment (partial response: 30–50%, poor: <30%). Results: Fifteen patients (age 49.1 ± 13.4 years, mean ± SD; 4 men) completed 8 session of BF and 14 patients (54.5 ± 17.6 years, 3 men) completed 8 session of ECMS. Four patients of BF group discontinued treatment due to unsatisfactory therapeutic effect (n = 1) and withdrew consent (n = 3) and 5 patients of ECMS group discontinued treatment because of same reasons (n = 1, 4). Total symptom scores were significantly decreased after treatment of 8 session in both treatment groups (13.4 ± 6.6 vs. 4.3 ± 4.0 for BF, p = 0.009; 14.9 ± 5.6 vs. 3.4 ± 4.0 for ECMS, p < 0.001). Bowel movements per week were also significantly increased after treatment in both groups (median 2 vs. 7 for BF, p = 0.035; median 2 vs. 7 for ECMS, p = 0.008). Thirteen out of 15 patients showed response in BF group and 12 out of 14 showed good response in ECMS group. No adverse effects in both groups. Conclusions: ECMS is as effective as BF for the treatment of PFD. Long‐term effect of ECMS for the patients with pelvic floor dyssynergia need to be evaluated in the near future. 相似文献

Background
Information on young patients with Brugada syndrome (BrS) and arrhythmic events (AEs) is limited.Objectives
The purpose of this study was to describe their characteristics and management as well as risk factors for AE recurrence.Methods
A total of 57 patients (age ≤20 years), all with BrS and AEs, were divided into pediatric (age ≤12 years; n = 26) and adolescents (age 13 to 20 years; n = 31).Results
Patients’ median age at time of first AE was 14 years, with a majority of males (74%), Caucasians (70%), and probands (79%) who presented as aborted cardiac arrest (84%). A significant proportion of patients (28%) exhibited fever-related AE. Family history of sudden cardiac death (SCD), prior syncope, spontaneous type 1 Brugada electrocardiogram (ECG), inducible ventricular fibrillation at electrophysiological study, and SCN5A mutations were present in 26%, 49%, 65%, 28%, and 58% of patients, respectively. The pediatric group differed from the adolescents, with a greater proportion of females, Caucasians, fever-related AEs, and spontaneous type-1 ECG. During follow-up, 68% of pediatric and 64% of adolescents had recurrent AE, with median time of 9.9 and 27.0 months, respectively. Approximately one-third of recurrent AEs occurred on quinidine therapy, and among the pediatric group, 60% of recurrent AEs were fever-related. Risk factors for recurrent AE included sinus node dysfunction, atrial arrhythmias, intraventricular conduction delay, or large S-wave on ECG lead I in the pediatric group and the presence of SCN5A mutation among adolescents.Conclusions
Young BrS patients with AE represent a very arrhythmogenic group. Current management after first arrhythmia episode is associated with high recurrence rate. Alternative therapies, besides defibrillator implantation, should be considered. 相似文献6.

聚羟基丁酸己酸酯/聚碳酸亚丙酯共混材料作为血管组织工程支架的性能特征 总被引:2,自引:3,他引:2
目的:为改善生物材料聚羟基丁酸己酸酯(PHBHHx)的力学性能和聚碳酸亚丙酯(PPC)的可加工性,将两者共混,制备不同比例的共混材料,并对共混膜上血管平滑肌细胞的黏附和共混材料制成的管形支架的力学性能进行评价,以选出合适比例的共混材料作为血管组织工程支架。
方法:实验于2006-08/2007-04在清华大学生物科学与技术系生物膜与膜生物工程国家重点实验室完成。①制备5种不同比例(PHBHHx∶PPC分别为0∶10,3∶7,5∶5,7∶3,10∶0)的共混材料,利用CCK-8试剂测定兔主动脉平滑肌细胞在共混膜上培养24h后的黏附数量。②采用热致相分离和冷冻干燥法制备管形支架,通过反复浸渍和晾干,在多孔支架外层形成一层晾干的膜层。利用扫描电镜观察支架形貌、压汞仪测量孔隙率和孔径分布,利用自制装置以6.65kPa/s的加压速度测定管形支架的破裂强度,万能材料试验机测定支架的缝合强度,以羊颈动脉为对照。
结果:①兔主动脉平滑肌细胞在各种膜上培养24h后,在5∶5比例PHBHHXx/PPC共混膜和PPC膜上相对黏附量高于PHBHHXx膜(P〈0.05)。②PHBHHx和共混材料均可制备成管形支架,而单纯PPC支架在制备晾干层时溶化,无法维持原形。管形支架的孔径随PPC含量的增加而增大,孔隙率提高。③支架的破裂强度与羊颈动脉相似(P〉0.05);缝合强度均强于羊颈动脉,以5∶5和3∶7PHBHHx/PPC共混材料制备的管形支架的缝合强度高于PHBHHx支架。
结论:①与PHBHHx相比,5∶5PHBHHx/PPC共混膜和PPC膜上兔主动脉平滑肌细胞的黏附更好。②共混材料均可以制备成管形支架,并且力学强度符合移植的要求,缝合强度以5∶5和3∶7的PHBHHx/PPC共混材料最佳。 相似文献

mRNA encoding the recently discovered P2Y(14) receptor has been reported in platelets, but the presence of P2Y(14) receptor protein and its functionality have not been studied. If P2Y(14) is expressed along with P2Y(1) and P2Y(12) receptors it may have a role in haemostasis. It was the objective of this study to investigate the presence of the P2Y(14) receptor in platelets and its role in platelet function. The effects of the agonist UDP-glucose were compared with those of sulprostone, a selective EP(3) receptor agonist. Expression of P2Y(14) receptor was investigated by immunoblotting and confocal microscopy. Platelet aggregation in platelet-rich plasma (PRP) and whole blood was measured using light absorbance and platelet counting. VASP phosphorylation was investigated using flow cytometry. Immunoblotting provided evidence for P2Y(14) receptor protein and microscopy confirmed its presence on platelets. Despite this, UDP-glucose (up to 100 muM) did not induce platelet aggregation in either PRP or whole blood, and did not potentiate aggregation induced by other agonists. P2Y(14) did not substitute for P2Y(12) in experiments using the P2Y(12) antagonist AR-C69931. No effect of UDP-glucose was seen on adenylate cyclase activity as measured by VASP phosphorylation. In contrast, sulprostone acting via the EP(3) receptor promoted platelet aggregation with effects on adenylate cyclase activity. EP(3) also partially substituted for P2Y(12) receptor. We have demonstrated the presence of P2Y(14) receptor protein in platelets, but no contribution of this receptor to several measures of platelet function has been observed. Further studies are necessary to determine whether the P2Y(14) receptor in platelets has any functionality. 相似文献
