抑郁症焦虑症状和焦虑症的抑郁症状

目的　探讨抑郁症和焦虑症的抑郁和焦虑症状的差异 ,为鉴别诊断提供依据。方法　使用HAMD和HAMA对5 5例抑郁症患者和 2 0例焦虑症患者进行评定。结果　 (1)抑郁症组绝大部分为中、重度抑郁 (92 .7% ) ,焦虑症组无一例为重度抑郁 ;(2 )抑郁症组的HAMD总分和除焦虑 /躯体化以外的因子分均显著高于焦虑症组 (P <0 .0 5或P <0 .0 1) ,(3)抑郁症患者和焦虑症患者的HAMD和HAMA评分均呈显著性正相关 (P <0 .0 0 1)。结论　HAMD总分有助于鉴别抑郁症和焦虑症。     

Manic episode with psychotic symptoms induced by subthalamic nucleus stimulation in a patient with Parkinson's disease.

Deep brain stimulation of the subthalamic nucleus (STN-DBS) is an established therapy for Parkinson's disease (PD). A manic episode with psychotic symptoms induced by STN-DBS occurred in a previously psychiatrically healthy patient, focusing on the role of STN-DBS in influencing not only motor but also emotional behaviour.     

Upper gastrointestinal tract dysfunction in bulimia

Bulimia nervosa is a health problem of increasing magnitude that is estimated to affect 2–5% of the American adolescent and young adult female population. Because of the magnitude of this clinical problem and because of the importance of the upper gastrointestinal tract in its expression, a intradepartmental program of health care for patients affected with the disease was initiated. Eleven consecutive symptomatic bulimic individuals have been evaluated jointly by the gastroenterology and the psychiatry departments of the University of Pittsburgh. Five of these 11 individuals were found to have clinically important upper gastrointestinal pathology including ulcerative esophagitis, erosive gastritis, duodenal ulcer, and delayed gastric emptying. These gastrointestinal conditions could have been either a result of or have contributed to the symptomatology of these five patients. These data suggest that bulimic subjects have clinically important gastroenterological disease processes that require specific diagnosis and treatment independent of the psychiatric treatment provided for the bulimic condition.This work was supported in part by grants from NIDDK AM 32556.     

Characteristics of open- and closed-loop smooth pursuit responses among obsessive-compulsive disorder, schizophrenia, and nonpsychiatric individuals

Twenty obsessive-compulsive disorder patients and comparison samples of 20 schizophrenia and 20 nonpsychiatric individuals were presented with (a) a step-ramp task designed to measure smooth pursuit initiation and (b) a regular ramp task designed to measure steady-stale tracking performance. Obsessive-compulsive disorder and non-psychiatric individuals had statistically similar pursuit reaction time and average eye accelerations during the open-loop interval. They also had similar closed-loop performance. Schizophrenia patients, however, had delayed pursuit reaction times and reduced eye acceleration during the last 60 ms of the open-loop interval. These findings suggest that brain regions supporting smooth pursuit performance are unimpaired among obsessive-compulsive disorder patients. Furthermore, the deficits found in the schizophrenia patients replicate and extend the results of previous smooth pursuit studies.     

血脂代谢紊乱与冠状动脉病变严重程度的关系

目的:分析血脂代谢异常与冠状动脉狭窄程度的关系.方法:对366例因胸痛而就诊的患者行选择性冠状动脉造影,按冠状动脉狭窄程度分为正常对照组、单支病变组、双支病变组、多支病变组.同时观察患者血脂各成分,并对各组指标进行统计学分析.结果:总胆固醇(TC)、甘油三脂(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C),在各组之间存在差异,尤其多支病变组与正常组之间差异显著(P＜0.01).TC、TG、LDL-C随冠状动脉病变加重而增加,HDL-C随冠状动脉病变加重而减少,LDL-C与冠状动脉狭窄程度呈正相关,HDL-C与冠状动脉狭窄程度呈负相关.结论:血脂代谢紊乱与冠状动脉狭窄的发生发展有内在的联系,对于预测有无冠状动脉病变及其进展有一定临床意义.     

以中医神志学说辨析百合病

运用神魂魄意志五神与五藏、五官、五体的配属关系．结合文献对百合病命名、病位、症状、病机及愈期判断加以探讨。提出百合病属中医神志失和类病变，由热病伤阴，余邪未尽．心肺阴虚，神志失养，加之情怀不畅，气郁不舒，百脉失调，形神失和而发病。     

儿茶酚-邻-甲基转移酶基因多态性与强迫症

目的：探索儿茶酚-邻-甲基转移酶(COMT)基因多态性同强迫症临床特征的关系。方法：采用聚合酶链反应扩增技术与限制性片段长度多态(PCR-RFLP)测定120例强迫症(OCD)患者和130例健康对照者的基因型；根据Yale-Brown强迫量表评分将强迫症划分亚型。结果：强迫症患者COMT基因型与等位基因分布与健康对照者之间无显著差异；强迫行为组与强迫思想组的COMT基因型分布存在差异；G／A基因型多见于强迫行为组。结论：COMT基因多态可能对强迫症的发病没有直接的作用，但G／A基因型可能对症状是否表现为强迫动作有一定的影响。     

丁螺环酮和阿普唑仑治疗广泛性焦虑研究

目的：比较国产丁螺环酮和阿普唑仑治疗广泛性焦虑的疗效和不良反应。方法：对78例广泛性焦虑按照就医顺序分为两组，分别服用丁螺环酮(38例)和阿普唑仑(40例)。疗程6周。于治疗前及治疗第1、2、4、6周末进行汉密尔顿焦虑量表(HAMA)及副反应量表(TESS)评定疗效和不良反应。结果：丁螺环酮和阿普唑仑的疗效相仿，丁螺环酮的不良反应少且轻微，无过度镇静和肌肉松弛作用，不产生药物依赖。结论：丁螺环酮是治疗广泛性焦虑较为理想的药物。     

Pituitary volume in pediatric obsessive-compulsive disorder.

BACKGROUND: Abnormalities in the limbic-hypothalamic-pituitary-adrenal (LHPA) axis have been implicated in the pathogenesis of obsessive-compulsive disorder (OCD). To our knowledge, however, no prior study has measured pituitary gland volume in OCD. METHODS: Volumetric magnetic resonance imaging studies were conducted in 31 psychotropic drug-na?ve children (10 boys, 21 girls) aged 8-17 years and 31 case-matched healthy comparison subjects. RESULTS: Pituitary volume was significantly smaller in patients with OCD as compared with healthy control subjects (11% smaller). Smaller pituitary volume in patients with OCD was associated with increased compulsive but not obsessive symptom severity. Boys with OCD had smaller pituitary gland volumes compared with control boys (20% smaller). No significant differences in pituitary volume were observed between girls with OCD and control girls. Boys with OCD had significantly smaller pituitary volumes than girls with OCD (31% smaller), whereas control boys also had smaller pituitary gland volumes compared with control girls (21% smaller). CONCLUSIONS: These findings provide new evidence of reduced pituitary volume in pediatric OCD that seems to be more prominent in male patients. The observed alterations in pituitary volume are consistent with neuroendocrine studies that have reported abnormalities in the LHPA axis in OCD.
