非那雄胺在慢性中心性浆液性脉络膜视网膜病变患者中的应用

目的评估非那雄胺治疗慢性中心性浆液性脉络膜视网膜病变(central serous chorioretinopathy,CSC)的有效性及安全性。方法选取2017年3月至2019年6月在本院确诊的慢性CSC患者31例40眼,采用单臂试验对患者进行非那雄胺治疗。使用非那雄胺治疗后6个月,对患者的视网膜神经上皮层(retinal neuroepithelial layer,RNL)下积液状况,ETDRS视力以及黄斑中心凹视网膜厚度(central foveal thickness,CFT)进行检查。结果非那雄胺治疗后1个月,有10眼(25.0%)RNL下积液完全消退。持续治疗2个月、3个月、4个月、5个月、6个月,分别有7眼(17.5%)、6眼(15.0%)、7眼(17.5%)、3眼(7.5%)及3眼(7.5%)RNL下积液消退,仅有4眼(10.0%)在治疗后6个月RNL下积液仍存在。患眼EDTRS视力非那雄胺治疗后1个月为(50.00±16.11)个字母,与治疗前(46.16±16.67)个字母差异无统计学意义(P=0.2213);治疗后2个月(53.39±14.67)个字母,较治疗前显著升高(P=0.0003);治疗后3个月、4个月、5个月、6个月,分别为(57.39±12.76)个字母、(58.52±12.39)个字母、(59.13±10.76)个字母及(60.42±10.96)个字母,与治疗前相比差异均有统计学意义(均为P<0.0001)。而患眼CFT自治疗后1个月、2个月、3个月、4个月、5个月、6个月分别为(274.10±22.74)μm、(273.00±17.22)μm、(263.50±12.81)μm、(263.90±10.62)μm、(259.70±12.48)μm及(252.60±11.00)μm,与治疗前(296.60±35.41)μm相比,差异均有统计学意义(均为P<0.05)。所有患者均无服药后身体不适或并发症发生。结论非那雄胺对于慢性CSC的治疗安全且有效,有望成为慢性CSC的治疗选择。     

Searching for Serum Antibodies to Neuronal Proteins in Patients With Myalgic Encephalopathy/Chronic Fatigue Syndrome

PurposeA role for the immune system in causing myalgic encephalopathy/chronic fatigue syndrome (ME/CFS) is long suspected, but few studies have looked for specific autoantibodies that might contribute to the symptoms. Our aim was to look for evidence of antibodies to neuronal proteins in patients with ME/CSF.MethodsSera samples from 50 patients and 50 healthy individuals were sent coded to the Neuroimmunology Laboratory in Oxford. Screening for antibody binding to neuronal tissue was performed on brain tissue and neuronal cultures. Specific serum antibodies were assessed by antigen-specific cell-based assays and radioimmunoassays. After antibody testing, the associations between seropositive status and clinical data were investigated.FindingsOverall, 8 patients and 11 participants were found to have some serum immunoreactivity toward neuronal or neuromuscular junction proteins, but only 1 patient and 2 participants had specific serum antibodies. Nevertheless, seropositive status in patients with ME was associated with shorter duration since onset and a more severe disease.ImplicationsThe results indicate no overall increased frequency of antibodies to neuronal proteins in ME/CSF and no evidence of a specific antibody that might be causative or contribute to clinical features in patients. However, the association of seropositive status with shorter duration of disease and more severe symptoms suggests a possible role of antibodies at onset in some patients and should be the focus of future studies.     

Research Priorities in Pelvic Venous Disorders in Women: Recommendations from a Multidisciplinary Research Consensus Panel

Pelvic venous disorders (PeVDs) in women can present with chronic pelvic pain, lower-extremity and vulvar varicosities, lower-extremity swelling and pain, and left-flank pain and hematuria. Multiple evidence gaps exist related to PeVDs with the consequence that nonvascular specialists rarely consider the diagnosis. Recognizing this, the Society of Interventional Radiology Foundation funded a Research Consensus Panel to prioritize a research agenda to address these gaps. This paper presents the proceedings and recommendations from that Panel.     

自血穴位注射疗法联合马来酸茚达特罗治疗老年稳定期慢性阻塞性肺疾病的临床分析

目的探讨自血穴位注射疗法联合马来酸茚达特罗治疗老年稳定期慢性阻塞性肺疾病(COPD)的临床疗效及其对患者炎性因子、免疫功能及肺功能的影响。 方法将2015年5月至2016年5月我院收治的86例老年缓解期COPD患者分为观察组与对照组。对照组给予马来酸茚达特罗治疗，观察组在对照组治疗基础上另给予自血穴位注射疗法。治疗12周后，评价2组临床疗效。治疗前及治疗12周后，分别检测2组患者肺功能指标(FEV₁、FVC与PEF)，炎性因子(IL-8、α1-AT、IL-6及TNF-α)，免疫功能指标(IgG、IgA、CD3^＋及CD4^＋)水平。治疗期间，对2组患者的不良反应进行密切观察。 结果治疗后二组患者各项检测指标均优于治疗前。治疗12周后，观察组总有效率为90.7%，明显高于对照组的72.1%(P<0.05)。治疗12周后，观察组FEV₁、FVC与PEF等肺功能指标，IgG、IgA、CD3^＋及CD4^＋等免疫功能指标水平均明显高于对照组(P<0.05)，而IL-8、α1-AT、IL-6及TNF-α含量分别为(23.23±3.87)ng/L、(3.43±0.41)g/L、(52.25±5.38)ng/L及(43.12±3.98)ng/L，改善程度均明显优于对照组(P<0.05)。治疗期间，2组患者均未出现严重不良反应。 结论自血穴位注射疗法联合马来酸茚达特罗治疗老年稳定期COPD疗效确切，可有效改善患者炎症水平，值得进行深入研究。     

Absence of FGFR3–TACC3 rearrangement in hematological malignancies with numerical chromosomal alteration

FGFR–TACC, found in different tumor types, is characterized by the fusion of a member of fibroblast grown factor receptor (FGFR) tyrosine kinase (TK) family to a member of the transforming acidic coiled-coil (TACC) proteins. Because chromosome numerical alterations, hallmarks of FGFR–TACC fusions are present in many hematological disorders and there are no data on the prevalence, we studied a series of patients with acute myeloid leukemia and myelodysplastic syndrome who presented numerical alterations using cytogenetic traditional analysis. None of the analyzed samples showed FGFR3–TACC3 gene fusion, so screening for this mutation at diagnosis is not recommended.     

Acute sensorineural hearing loss in hemodialysis patients

Abstract

Background: Approximately, 30–40% of patients experienced hearing loss under regular hemodialysis.

Objective: This study reviewed our experience on treating acute hearing loss in patients under regular hemodialysis over the past two decades.

Methods: Twenty-six patients having acute hearing loss under hemodialysis were divided into two groups based on their etiologies. Sixteen patients (16 ears) with sudden sensorineural hearing loss (SSHL) were assigned to Group A and 10 patients (13 ears) with endolymphatic hydrops (EH) were assigned to Group B.

Results: No significant difference was noted between Groups A and B, regardless of hemodialysis duration, clinical manifestation, underlying systemic diseases, blood examination, and vestibular test battery. In contrast, serum osmolality was significantly lower in Group B (292?±?11 mOsm/kg) than in Group A (310?±?11 mOsm/kg). Furthermore, Group B (40?±?14?dB) had better mean hearing level than Group A (87?±?21?dB) in the initial audiogram, and a higher hearing improvement rate (69%) than Group A (19%).

Conclusions and significance: Both SSHL and EH are major causes for precipitating acute hearing loss in hemodialysis patients. Compared to SSHL, the less deteriorated MHL and lower serum osmolality in EH provide two clues for differentiating acute hearing loss in hemodialysis patients.
