高海拔地区精神分裂症患考临床特征分析

目的:了解高海拔环境对精神分裂症的影响。方法:对106例高海拔地区精神分裂症患者(高海拔组)的临床特征、疗效、药物副作用进行调查,与同期106例平原精神分裂症患者(平原组)对照。结果:高海拔组临床症状以幻觉、疑病妄想、夸大妄想、紧张冲动行为及焦虑、抑郁等精神症状出现频率较高,而对照组以被害妄想、情感淡漠等精神症状出现频率较高(P<0.01或P<0.05);入院时高海拔组总体病情较重(P<0.01);两组间疗效无显著性差异;高海拔组药物不良反应多于平原组。结论:高海拔地区精神分裂症患者临床特征、总体病情严重程度、药物不良反应与平原地区有一定区别,可能与高海拔环境有关。     

The Present and Future of Clinical Psychology in Private Practice

This article discusses clinical psychologists' current concerns, challenges, and opportunities in private practice. The future of clinicians in independent practice is presented within two paradigms, namely, psychology as a health profession, and psychology as life enhancement. Finally, the author argues that psychotechnology, corporate clinical psychology, and psychology as life enrichment will evolve within the future of clinical psychological independent practice.     

模拟舰船磁场与噪声、高温复合对机体作用的方差分析

目的 研究模拟舰船两种剂量水平磁场复合噪声、高温对机体联合作用的特点。方法 采用有交互作用的三因素二水平的正交试验设计方法及方差分析法，按正交表L8（2^7）的要求安排8种复合暴露剂量组合，分别将兔和大鼠分为8个复合暴露组和8个对照组。结果 兔球结膜毛细血管管径、大鼠肝和脾脏HSP70的分析结果显示出磁场是对其影响的主因素（均为P〈0．01），其次是高温（均为P〈0．05）,大鼠下丘脑AVP和大鼠脑组织HSP70的分析结果显示出磁场是对其影响的主因素（均为P〈0．05）。兔血浆内皮素的分析结果显示出磁场与噪声交互作用所对应的F值有非常显著性意义（P〈0．01），磁场与噪声、高温三者之间交互作用所对应的F值也有显著性意义（P〈0．05）。结论 磁场是对上述指标影响的主因素，而高温也是重要因素；磁场与噪声有交互作用，磁场与噪声、高温三者之间也有交互作用；应该重视舰船环境因素对舰船人员的复合作用。     

Acute Inflammatory Syndrome Induced by Mycophenolate Mofetil in a Patient Following Kidney Transplantation

Mycophenolate mofetil (MMF) is increasingly used to prevent acute and chronic rejection following kidney transplantation and in autoimmune diseases. Here, we report on a patient after kidney transplantation, who developed an acute inflammatory syndrome characterized by fever and oligoarthritis within 1 week after increasing the MMF dosage. MMF was discontinued resulting in a complete resolution of the syndrome within 48 h. We demonstrated in vitro that the patient's phorbol myristate acetate (PMA-) and formyl Met-Leu-Phe (fMLP-) stimulated polymorphonuclear neutrophils (PMNs) developed increased oxidative burst when incubated with MMF. This report demonstrates that MMF can also induce acute inflammatory syndrome in patients following kidney transplantation and that this syndrome might be due to a paradox, pro-inflammatory reaction of PMNs.     

Comparison of parent and teacher reports of attention-deficit/hyperactivity disorder symptoms from two placebo-controlled studies of atomoxetine in children.

BACKGROUND: The validity of parent reports regarding children's attention-deficit/hyperactivity disorder (ADHD) symptoms has been questioned. This study assessed whether parent reports were as sensitive as teacher reports to document change in ADHD symptoms during clinical trials with atomoxetine. METHODS: Data were compared from two randomized, double-blind, placebo-controlled clinical trials of atomoxetine using different versions (parent or teacher) of the same rating scale (Attention-Deficit/Hyperactivity Disorder Rating Scale-IV [parent or teacher] Version: Investigator Administered and Scored - ADHD RS). Exclusion criteria included history of bipolar disorder, psychosis, seizures, alcohol abuse, or positive drug screen. Patients (6-16 years old) were treated with atomoxetine (titrated to a maximum dose of 1.8 mg/kg/day) administered once daily for up to 7 weeks. Parent and teacher ratings were compared using an analysis of covariance (ANCOVA) model. RESULTS: The analysis (n = 318) showed that treatment effects (mean change, baseline to endpoint) were similar between parent and teacher ratings (total, p = .762; inattention, p = .519; hyperactive/impulsive, p = .955). Effect sizes also were similar based on total scores (parent ratings = .69; teacher ratings = .63). CONCLUSIONS: Parent reports are as sensitive as teacher reports in assessing the efficacy of long-acting pharmacologic treatment for ADHD in children during clinical trials using the nonstimulant atomoxetine.

Critical study of hair growth analysis with computer-assisted methods

BACKGROUND: Computer-assisted image analysis has been proposed for human hair growth studies. METHODS: The performances of Trichoscan, a commercially available automated system combining epiluminiscence microscopy with digital image analysis, developed for office-based hair growth measurements, have been evaluated comparatively on the same skin sites using standardized photographic equipment and calibrated processing for contrast-enhanced phototrichogram (CE-PTG) analysis. This reference method has been validated with scalp biopsies and histological examination of serial sectioning. RESULTS: Besides edge effects, hair fibres escaped the Trichoscan analysis for various reasons including, but not limited to, thickness, pigmentation, closeness and crossing. CONCLUSION: Most of these problems have been identified in the late 1980s and remain largely unsolved by the processing software that was evaluated in 2004. Therefore claims promoting the Trichoscan method for accurate hair measurements in clinical trials on scalp and body hair are not supported by the present investigation. The speed at which the analysis is performed is outweighed by the errors in signal detection. Therefore we suggest that improvements must be clearly documented before Trichoscan is established for quantified diagnostic purposes and detailed hair cycle monitoring during hair trials.     

菜心富硒规律及其对营养成分的影响

选用菜心作为富硒的研究对象，采用不同质量浓度的亚硒酸钠进行喷施处理，测定总硒和有机硒的含量以及不同的富硒浓度对菜心植株产量和各营养成分的影响。结果显示：喷施低浓度硒可以增进菜心品质而高浓度硒则抑制了菜心植株的正常生长和生理代谢。在富硒菜心中，75％以上的硒以有机硒的形式存在，体内的无机硒主要以6价硒存在，6价硒占总无机硒的94％以上；硒可以明显的提高菜心叶绿素、蛋白质、维生素C和氨基酸的含量，但可溶糖的含量降低。     

The multiform and variable patterns of onset of orofacial granulomatosis

BACKGROUND: The recurrent chronic orofacial swelling caused by orofacial granulomatosis (OFG) can cause significant cosmetic and functional problems but can be prevented if the disease is diagnosed early and promptly treated. Although the enlargement of the lips is described to be the most common presenting complaint, the clinical onset of OFG may be characterized by minor associated mucosal and neurological manifestations, making early diagnosis very difficult or, sometimes, merely presumable. PATIENTS AND METHODS: We retrospectively analyzed the clinical manifestations of 19 patients with OFG, who were examined at our institution between 1998 and 2002, in order to determine their initial manifestations and presenting symptoms. RESULTS: A total of 10 patients showed classical recurrent enlargement of the lips (six lower; four upper) as presenting symptom. In the other nine patients, OFG onset was characterized by transient unilateral facial nerve palsy (two cases), intraoral manifestations (two cases), recurrent swelling of the periorbital area (two cases), of the chin (one case), of the zygomatic area (one case), and of the cheeks (one case). CONCLUSION: Our data underlined that OFG onset could be frequently characterized by widely variable, multiform, and temporary clinical findings. Involvement of atypical sites of the orofacial region and presence of single minor manifestations may occur as presenting symptoms, often preceding the development of traditional clinical findings.
