Detecting pediatric autoimmune neuropsychiatric disorders associated with streptococcus in children with obsessive-compulsive disorder and tics.

BACKGROUND: A subgroup of children with obsessive-compulsive and tic disorders are proposed to have an infectious trigger. The purpose of this study was to investigate the relationship between group A streptococcal titers and symptom fluctuations in children with a clinical course resembling that described for pediatric autoimmune neuropsychiatric disorders associated with streptococcus. METHODS: Twenty-five children with obsessive-compulsive disorder and/or tic disorder were evaluated for neuropsychiatric severity and group A streptococcal antibody titers (streptolysin O, deoxyribonuclease B, and carbohydrate A) at 6-week intervals for > or = six consecutive evaluations (total visits=277). RESULTS: Children with large symptom fluctuations (n=15) were compared with children without dramatic fluctuations (n=10). Co-movements of obsessive-compulsive/tic severity and group A streptococcal antibodies were assessed. In subjects with large symptom changes, positive correlations were found between streptococcal titers and obsessive-compulsive severity rating changes (p=.0130). These subjects were also more likely to have elevated group A streptococcal titers during the majority of observations (p=.001). Tic symptom exacerbations occurred more often in the fall/winter months than spring/summer months (p=.03). CONCLUSIONS: Patients with marked obsessive-compulsive/tic symptom changes may be characterized by streptococcal titer elevations and exhibit evidence of seasonal tic exacerbations.     

体外培养诱导外周血淋巴细胞促进大鼠面神经再生的实验研究

目的:通过在神经缺损处局部回输体外分离培养纯化的淋巴细胞,了解此种方法促进面神经损伤修复的效果。方法:将20只Wistar大鼠的面神经颊支剪断并立即缝合(其余3支反折缝合)制成面神经损伤模型大鼠,将其分成淋巴细胞组和对照组,每组10只,每组再分成2周组和8周组。淋巴细胞组局部回输体外分离培养的外周血淋巴细胞,对照组作对照。于2周和8周测定面神经颊支-触须肌复合动作电位传导速度,辣根过氧化物酶(HRP)神经逆行示踪测定面神经核团的神经元阳性数目。结果:淋巴细胞组面神经颊支-触须肌复合动作电位传导速度8周时为0.64±0.07,与对照组(0.56±0.07)相比,差异有统计学意义(P<0.05)。HRP神经逆行示踪测定面神经核团神经元阳性数目,淋巴细胞组2周及8周与对照组同时间段相比差异均无统计学意义(均P>0.05)。结论:体外分离培养纯化的淋巴细胞在局部应用于神经损伤处对面神经再生修复可起一定的促进作用。     

Transmyocardial revascularization ameliorates ischemia by attenuating paradoxical catecholamine-induced vasoconstriction

Background  The mechanism by which transmyocardial revascularization (TMR) offers clinical benefit is controversial. We hypothesized that TMR ameliorates ischemia by reversing paradoxical catecholamine-induced vasoconstriction. Methods and Results  Chronic ischemic cardiomyopathy was created in 11 dogs by placing ameroid constrictors on the proximal coronary arteries and their major branches. Six weeks later, 35 channels were created percutaneously in the left circumflex artery region, with the left anterior descending artery region serving as control. At rest, wall thickening and myocardial blood flow did not change in the treated region, whereas they deteriorated in the control bed. Contractile and myocardial blood flow reserve increased in the treated region but deteriorated in the control region. There was diminished iodine 123 metaiodobenzylguanidine uptake and a significant reduction in noradrenergic nerves in the treated region compared with the control region, with a corresponding reduction in tissue tyrosine hydroxylase activity. Conclusions  We conclude that the absence of a catecholamine-induced reduction in MBF reserve and contractile reserve in the TMR-treated region with associated evidence of neuronal injury indicates that the relief of exercise-induced ischemia after TMR most likely results from reversal of paradoxical catecholamine-induced vasoconstriction. These findings may have implications in selecting patients who would benefit from TMR. Supported in part by grants from the National Institutes of Health (R01-HL66034 and K-08-HL074290-01). Bethesda.

实验性腹主动脉瘤瘤体外径与iNOS相关性分析及分期研究

Objective To construct new model of experimental abdominal aortic aneurysm (AAA) and detect the AAA outer diameter and the change of induce nitric oxide synthase(iNOS) in the abdominal aor-tic aneurysm in different period,and analysis the correlation between experimental AAA and iNOS.Methods During the operation of the experiment group,the vascular prosthesis of PTFE was implanted to the rabbit abdominal aorta to form an aneurysm,while sham operation was done in the control group.The tissue of ab-dominal aortic aneurysm was harvested in 1 d,7d,14d,and 28d after operation,respectively.The tissue bo-mogenate concentration of iNOS in the abdominal aortic aneurysm were detected by enzyme linked immu-nosorbent assay (ELISA).Results In experimental group,mean concentration of the tissue bomogenate concentration of iNOS in the abdominal aortic aneurysm in 1 d,7 d,14 d,28 d were (22.129 ±2.518)μ/mL,(27.337±5.321) μ/mL,(36.047±4.584)μ/mL,(44.756±1.799)μ/mL,respectively;In control group,that was (12.499±1.807)μ/mL.The concentration of iNOS in experimental group was significantly higher than that of control group (P < 0.01).The difference during the experimental group all had statisti-cal significance (P < 0.05).Conclusion It is possible that iNOS has some biological function during the formation and progression of the abdominal aortic aneurysm.     

Smoothing the mosaic subclinical melanoderma by calcipotriol

BACKGROUND: The observation of photo-exposed skin under ultraviolet light reveals a mosaic pattern of varying intensity in epidermal melanization. Several patterns of mosaic subclinical melanoderma (MSM) have been described using a specially designed CCD camera and the ultraviolet light-enhanced visualization (ULEV) method. Vitamin D(3) and its analogues influence the biology of keratinocytes and melanocytes. OBJECTIVE: To assess the effect of calcipotriol on MSM. METHODS: This randomized split-face study was conducted in 27 men to compare the effect of once daily applications of 5% calcipotriol cream or a moisturizing cream on the heterogeneity of facial MSM. Computerized image analysis of video images was used at 1-month intervals before and during a 2-month treatment, as well as during a 3-month follow-up. RESULTS: At both sites, the average melanin content of the epidermis showed no significant change over time. However, the mottled appearance was smoothened at the calcipotriol site, whereas it was increased at the site receiving the moisturizer. CONCLUSION: The decreased heterogeneity in MSM after calcipotriol applications suggests a control of the epidermal melanocyte unit by the vitamin D(3) derivative.     

红景天对高原去势大鼠骨质疏松症的血清IL-6、TNF-α和尿DPD影响

目的:探讨高原高寒地区低氧环境去势大鼠骨质疏松症与血清白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)和尿脱氧吡啶酚(DPD)的关系及红景天预防骨质疏松的作用。方法:选用Wistar雌性大白鼠75只,分别摘除卵巢或假性去卵巢。分为A组(假手术组),B组(切除卵巢组),C组(切除卵巢 尼尔雌醇组),D组(切除卵巢 红景天混合饲料组),E组(切除卵巢 红景天浸液组)。每组15只,术后在海拔3100m青海海北州地区饲养,术后3个月处死,应用放免方法测定血清IL-6、TNF-α和化学发光法测定尿中DPD含量。结果:B组血清IL-6、TNF-α和尿DPD含量显著高于A、C、D、E组。C、D、E组血清IL-6、TNF-α和尿DPD含量与A组比较差异无显著性统计学意义。结论:红景天的抗高原骨质疏松症的作用可能与降低血清IL-6、TNF-α含量和尿中DPD浓度有关。
