The introduction of treatment and the cultural adaptability of western psychotherapies for eating disorders in China

In the past 40 years, the prevalence of eating disorders (ED) in China has shown an increasing trend, leading to an urgent need to develop efficient treatment modes and methods. Since the beginning of the new century, the diagnosis, treatment, and research of ED in China have been under development. This article gives an introduction and commentary on the treatment modes, treatment methods and their applications in ED in China. There are two main treatment forms for ED until now, that is, inpatient treatment and outpatient treatment. Inpatient treatment is recommended as the first choice. Since 2008, clinical psychotherapies such as cognitive behavioral therapy (CBT), dialectical behavioral therapy (DBT), and family-based treatment (FBT), which are effective for pathological symptoms of ED, have been introduced into China and developed clinically. Group CBT and group DBT for patients with ED and group FBT for caregivers might be the most efficient psychotherapy in China nowadays. A multi-family FBT support group could be developed as the basic treatment of ED patients. Although these new types of psychotherapy have observed effectiveness in clinical application, the Randomized Controlled Trials (RCT) are rare and need to be developed.     

Identification and characterization of lipopolysaccharide-binding proteins on human peripheral blood cell populations.

Previous research in this laboratory, using photoactivatable radioiodinated lipopolysaccharide derivatized with sulfosuccinimidyl-2-(p-azidosalicylamide)-1,3'-dithiopropionate (125I-ASD-LPS), has resulted in the identification of a specific LPS receptor with a molecular mass of approximately 73 kDa on murine lymphocytes and splenic macrophages. The experiments presented in this report investigated whether a similar LPS-binding protein was also expressed on human peripheral blood populations, including monocytes, lymphocytes, neutrophils, platelets, and erythrocytes. Each cell population was incubated with 125I-ASD-LPS, UV irradiated, washed, reduced, and solubilized, and the cell lysates were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis followed by autoradiography. On all of the cell populations, except erythrocytes, a similar 73-kDa LPS-binding protein was present. In addition, each population also expressed lower-molecular-weight secondary LPS-binding proteins, some of which were conserved among the populations. Binding of the photoactivatable LPS probe was found to be both time and temperature dependent. These data support the concept that the 73-kDa LPS-binding protein is conserved on multiple cell types from a variety of species.

模式翻转视觉诱发电位快速提取的可行性再研究

目的把模式翻转视觉诱发电位快速提取法应用于视神经病变的病人,探讨其临床应用价值。方法应用Galileo视觉诱发电位检测系统对30例正常健康人和17例视神经疾病病人分别进行全视野的PRVEP检测熏每一结果重复检测3次。所得结果应用少次提取法进行处理而得VEP波形。然后将正常对照组3次重复结果两两间分别进行配对t检验,探讨其可重性,并计算出正常值范围,最后参照正常值,分析视神经疾病组的检测结果。结果3次重复结果两两间配对t检验,得P1=0.425>0.05,P2=0.179>0.05,P3=0.110>0.05;参照本研究得出的正常值范围,对病人组的检测结果进行分析,得出这种少次提取法对视神经疾病检测的敏感度90.0%(18/20),特异度92.5%(13/14),准确度91.1%(31/34)。结论用这种少次提取法提取PRVEP,可重性好,稳定可靠。很有临床应用价值。     

不同机制大动脉粥样硬化型脑卒中基线特征和血管内治疗后结局比较

目的 本研究旨在比较颅内大血管伴/不伴同侧颈内动脉闭塞的大动脉粥样硬化型脑卒中患者基线特征以及行血管内治疗后结局的差异。方法 对DIRECT-MT亚组进行回顾性分析,以比较前循环大动脉粥样硬化（large-artery atherosclerosis,LAA）型卒中串联闭塞和颅内闭塞接受血管内治疗（endovascular treatment,EVT）的患者的基线特征和预后,分析不同机制学特征（动脉粥样硬化或动脉-动脉栓塞）对临床结局的影响。结果 LAA型卒中患者共108例,其中串联闭塞63例,颅内闭塞45例。颅内闭塞组患者高血压史率高于串联闭塞组（77.8% vs. 52.4%, P=0.007）。颅内闭塞组闭塞部位最常见于大脑中动脉M1段（88.6%）,而串联闭塞组颅内闭塞主要位于颈内动脉颅内段（49.2%）和大脑中动脉M1段（49.2%）（P＜0.001）。两组患者在年龄、性别、术前抗栓、他汀类药物的使用,卒中、房颤、吸烟史,基线mRS、NIHSS评分,是否静脉溶栓,侧枝循环,以及救治流程时间差异均无统计学意义（P均＞0.05）。90天mRS 0-2分的患者比例两组差异无统计学意义（53.3% vs. 41.9%, P=0.243）。颅内闭塞组术后成功再灌注率高于串联闭塞组（93.3% vs. 77.4%, P=0.026）,但术后24-72小时血管再通的比例前组低于后组（57.1% vs. 77.2%, P=0.034）。最终梗死体积,颅内闭塞组小于串联闭塞组（20.1 vs. 34.5, P=0.025）。术后NIHSS评分,90天EQ-5D-5L评分和BI指数等其他次要结局,两组间差异无统计学意义（P均＞0.05）。两组在90天内的死亡率,发生的无症状性和症状性颅内出血率,5-7天时在另外的血管区域新发脑梗死,以及新流域栓塞的患者百分比相似,差异无统计学意义（P均＞0.05）。结论 动脉粥样硬化导致的串联闭塞相较于孤立颅内闭塞,末次造影成功再灌注率较低,梗死体积更大,但术后24-72小时再通率更高,且神经功能良好预后率以及不良事件发生率均与颅内闭塞相仿。
