目的 探讨银屑病患者自我概念与社交回避及苦恼的关系.方法 运用自我概念量表(SCS)和社交回避及苦恼量表(SADS)对80例银屑病住院患者进行调查,并进行相关性分析.结果 银屑病患者的SCS得分为122.35±10.03.处于中度负性水平;SADS得分为16.32±6.13.显著高于正常人(P<0.01);银屑病患者的自我概念及各因子与社交回避及苦恼存在显著负相关(P<0.05,P<0.01).结论 银屑病患者的自我概念与社交回避及苦恼现象应引起护理人员高度重视,需提高患者的正性自我概念,以改善其社交回避及苦恼状况.     

Connectome spectrum electromagnetic tomography: A method to reconstruct electrical brain source networks at high-spatial resolution

Connectome spectrum electromagnetic tomography (CSET) combines diffusion MRI-derived structural connectivity data with well-established graph signal processing tools to solve the M/EEG inverse problem. Using simulated EEG signals from fMRI responses, and two EEG datasets on visual-evoked potentials, we provide evidence supporting that (i) CSET captures realistic neurophysiological patterns with better accuracy than state-of-the-art methods, (ii) CSET can reconstruct brain responses more accurately and with more robustness to intrinsic noise in the EEG signal. These results demonstrate that CSET offers high spatio-temporal accuracy, enabling neuroscientists to extend their research beyond the current limitations of low sampling frequency in functional MRI and the poor spatial resolution of M/EEG.     

表浅型食管癌经内镜黏膜下剥离术导致非治愈性切除的危险因素及长期生存分析

目的探讨表浅型食管癌(SEC)经内镜黏膜下剥离术(ESD)后导致非治愈性切除的危险因素及其预后情况。方法回顾性分析214处SEC病变(207例患者)行食管ESD治疗的情况。共随访15～102月,中位随访时间48月。结果所有病例中,整块切除率89.25%(191/214),完全切除率80.84%(173/214),治愈性切除率70.09%(150/214),非治愈取切除率29.91%(64/214),切除标本最大长径110 mm。单因素分析结果显示,年龄、性别、肿瘤体积、术时病灶抬举情况和手术时间与术后导致非治愈性切除相关(P<0.05)。多因素分析结果显示:女性、肿瘤长径≥50 mm、术时病灶抬举欠佳是术后导致非治愈性切除的危险因素。在非治愈切除组中,ESD后无任何相关治疗的患者与接受开放手术的、放化疗的患者的无癌生存期、生存期差异均无统计学意义。结论对于一般状况差的、不愿行外科手术及放化疗的非治愈性切除患者,定期内镜检查亦不失为一个可能的选择。

Moxibustion treatment increases the survival rate of lung infection of patients bed-ridden due to osteoporotic fracture of the spine via regulation of the inflammatory responses

IntroductionThis study aimed to investigate the potential role of moxibustion (MOX) in the treatment of lung infection in patients bed-ridden due to osteoporotic fracture of the spine.Methods96 senile patients with pulmonary infection who were bed-ridden due to osteoporotic fracture of the spine were grouped into a MOX (–) group and a MOX (+) group. An animal model was established as a SHAM group, a PRIMED group, a MOX 15’ group and a MOX 30’ group.ResultsFor the patients’ study, we found that the survival rate was higher for patients who received MOX. Moreover, tumor necrosis factor-α, interleukin (IL) 1β, IL-6 and IL-18 were down-regulated while IL-10 was up-regulated by MOX. MOX time-dependently increased the survival while reducing the bacteria left in infected mice.ConclusionsMoxibustion significantly alleviated the inflammatory responses, thus leading to a better survival rate of patients bed-ridden due to osteoporotic fracture of the spine.     

High hemoglobin fluctuation was a protective factor for cardiovascular‐related death in peritoneal dialysis (PD) patients: A retrospective analysis of 232 patients with PD

ObjectivesThis study aimed to investigate the effect of hemoglobin (Hb) fluctuation after dialysis on the prognosis of cardiovascular‐related and all‐cause deaths in peritoneal dialysis (PD).MethodsAccording to the Hb fluctuation, patients were divided into low fluctuation group, moderate fluctuation group, and high fluctuation group, and then, the effects of Hb fluctuation after dialysis on the prognosis of cardiovascular‐related and all‐cause death in PD were analyzed by regression analysis.ResultsA total of 232 patients were selected in this study. Compared with the low Hb fluctuation group, the moderate and high fluctuation groups had lower body mass index (BMI), estimated glomerular filtration rate (eGFR), and baseline Hb, and the moderate fluctuation group had less erythropoietin (EPO) and dialysis dose. Compared with survivors, patients with cardiovascular‐related and all‐cause deaths had lower mean Hb and Hb fluctuation (all p < 0.05). Cox regression analysis showed that before and after adjusting for confounding factors, Hb fluctuation was still independently correlated with cardiovascular prognosis, and higher Hb fluctuation was still a protective factor for cardiovascular‐related death in the Hb‐substandard group, but there was no significant correlation between Hb fluctuation and all‐cause death. Multivariate linear regression analysis revealed that Hb fluctuation was positively correlated with Kt/V and EPO dosage, but negatively correlated with the baseline Hb.ConclusionHigh Hb fluctuation was a protective factor for cardiovascular‐related death in PD with substandard Hb. Compared with Hb fluctuation, correction of anemia timely and making Hb reaches the standard level had a greater impact on reducing cardiovascular‐related death in PD.
