中药解郁胶囊治疗老年抑郁症的临床疗效观察

目的：观察中药解郁胶囊对老年抑郁症的临床疗效和安全性。方法：选取2020年11月至2021年12月甘肃中医药大学附属医院住院或门诊患者200例作为研究对象,按照纳入标准最终产生研究观察对象100例,健康对照组来自我院组织的年龄在60~80岁的健康体检的老年人100例。观察组中男37例,女63例,对照组中男43例,女57例。对照组采取常规治疗,观察组采取中医综合疗法治疗。对2组患者治疗前后减分情况、中医证候分析、服药及依从情况、不良反应及抑郁焦虑因子等无创性指标的影响。结果：对老年抑郁症的治疗效果主要从汉密尔顿抑郁量表减分情况及证候减分率体现,2组经过12个月中药和抗抑郁综合治疗,中医证候量表减分率（8.2±3.1）和（7.8±3.2）,比对照组的（8.8±3）与（8.4±3.6）,P值为0.001 6和0.001 3,治疗前后均有明显变化,差异有统计学意义（P<0.05）,中医证候量表减分率比较,差异有统计学意义（P<0.05）,从服药后出现的不良反应来看,中医综合观察组应明显低于对照观察组,差异有统计学意义（P<0.05）。从中医组治疗患者的依从性分析,差异有统计学意义（P<0.05）。结论：中药解郁胶囊与中医综合治疗患者治疗效果显著,依从性更佳。

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。
