A case of Ullrich disease with distinct pathological change of muscular dystrophy

A case of Ullrich disease was presented. The patient was a 3-year-old girl with torticollis, generalized muscle weakness and acroatonia since birth. High-arched palate, protruded calcaneus, and mild contracture of proximal joints were also recognized. Intellectual development was normal. Serum level of CPK was slightly increased. In histological and histochemical examinations of quadriceps femoris muscle, proliferated connective tissue, marked variation in the muscle fiber diameter, and a lot of degenerated and regenerated fibers were recognized. Minimal injury easily causes subcutaneous hemorrhage, but no abnormality was found in the structure of collagen.     

西药对中医脉象的影响

笔者毕业后十余年中,临床上遇到心脑血管病人大部分正在应用西药治疗,中医讲究辨证论治,西药是否影响中医的辨证,临床上脉象是否随着西药运用而改变呢?中医脉象学是中医诊病、治病重要手段,望闻问切中“切诊”是主要组成部分。脉象变化是辨证论治重要依据,求证离不开脉象,组成脉象的主要因素及原因有:①脉位:脉动显现部位的浅深,脉位表浅为浮脉,深沉为沉弦;②至数:脉搏的频率,以一个呼吸周期为单位,一息脉来四~五至为平脉,一息六至为数脉,一息三至为迟脉;③脉长:脉动应指的轴向范围长短,越超三部脉象称为长脉,应指不及三部,但见关部或寸部者…     

Changes in immune regulation in response to examination stress in atopic and healthy individuals

BACKGROUND: Stress can aggravate the allergic inflammation, but determinants of disturbed immune regulation are largely unknown. OBJECTIVE: To determine systemic immunological, local inflammatory and functional airway responses to stress in healthy and atopic individuals. METHODS: Forty-one undergraduate students, 22 with allergy of whom 16 had asthma, and 19 healthy controls, were studied in a low-stress period and in association with a large exam. Subjects completed questionnaires on stress and health behaviours, underwent lung function tests, bronchial methacholine challenge, measurements of exhaled nitric oxide and urine cortisol. Blood cells were phenotyped, and cytokines from mononuclear blood cells were analysed. RESULTS: Perceived stress and anxiety increased in both groups during the exam period while cortisol increased only in the atopy group. Cytokine production decreased broadly in response to stress in both groups, which was paralleled by an increase in the proportion of regulatory T cells (CD4(+)CD45RO(+)CD25(bright)). Interestingly, atopic individuals, but not controls, reacted with a decreased T-helper type 1/T-helper type 2 (Th1/Th2) ratio and a decrease in natural killer (NK) cell numbers in response to stress. In control subjects only, exhaled nitric oxide decreased and forced expiratory volume in one second increased during stress. CONCLUSION: Atopic and non-atopic subjects shared some immune changes in response to stress, such as a dramatic decline in cytokines and an increase in the number of regulatory T cells in peripheral blood. However, other stress-induced immune changes were unique to atopic individuals, such as a skewed Th1/Th2 ratio and reduced NK cell numbers, indicating that some pathogenic mechanisms in atopics may be more strongly affected by stress than others.     

自制32P敷贴器治疗瘢痕疙瘩

目的：观察自制32P敷贴器局部敷贴治疗不同类型瘢痕疙瘩的临床疗效。 方法：105例瘢痕疙瘩患者中，39例病变厚度≤ 0.3 cm的行单纯敷贴治疗，病变厚度> 0.3 cm的66例随机分为2组，单纯敷贴组36例，手术+敷贴组30例。单纯敷贴根据病变表面积大小及形状剪取敷贴片，根据剂量率和衰变校正计算每天敷贴时间，直接贴于病变表面，每天4.0~5.0 Gy/(部位•次)，连续4 d为一疗程，每疗程间隔4周，总治疗4~6个疗程。幼儿单次剂量控制在每天4 Gy/(部位•次)以下。手术+敷贴组患者手术切除瘢痕疙瘩，待手术伤口无渗出后根据伤口形状剪取敷贴片对准伤口敷贴，剂量及疗程同单纯敷贴组。 结果：单纯敷贴治疗对病变厚度≤0.3 cm的39例瘢痕疙瘩治愈32例(82%)，总有效率98%；对病变厚度> 0.3 cm的瘢痕疙瘩单纯敷贴和手术+敷贴两组治疗总有效率分别为56%和93% ，两组差异有显著性意义(P < 0.01)，其中病程< 9个月的患者治疗有效率分别为25%和75%，病程较长患者治疗有效率分别为13%和77%。治疗过程中有26例在敷帖过程中出现局部皮肤烧灼和刺痛感，均以炉甘石洗剂局部外用处理后缓解；5例出现Ⅰ度放射性皮炎，2例出现Ⅱ度放射性皮炎，以百多邦软膏局部外用后缓解，无出现Ⅲ度以上放射性皮炎病例。治愈患者局部皮肤均有不同程度的色素沉着或皮肤颜色改变。 结论：32P敷贴治疗瘢痕疙瘩治疗安全有效，对病程较短或病变厚度小于0.3 cm的患者可单纯敷贴治疗，病程较长或病变厚度大于0.3 cm患者建议先手术后再敷贴治疗。     

Cross-cultural invariance of the Academic Expectations Stress Inventory: Adolescent samples from Canada and Singapore

We provide further evidence for the two-factor structure of the 9-item Academic Expectations Stress Inventory (AESI) using confirmatory factor analysis on a sample of 289 Canadian adolescents and 310 Singaporean adolescents. Examination of measurement invariance tests the assumption that the model underlying a set of scores is directly comparable across groups. This study also examined the cross-cultural validity of the AESI using multigroup confirmatory factor analysis across both the Canadian and Singaporean adolescent samples. The results suggested cross-cultural invariance of form, factor loadings, and factor variances and covariances of the AESI across both samples. Evidence of AESI's convergent and discriminant validity was also reported. Findings from t-tests revealed that Singaporean adolescents reported a significantly higher level of academic stress arising from self expectations, other expectations, and overall academic stress, compared to Canadian adolescents. Also, a larger cross-cultural effect was associated with academic stress arising from other expectations compared with academic stress arising from self expectations.     

Modified Epworth Sleepiness Scale in Chinese children with obstructive sleep apnea: a retrospective study

Background and objective  The purpose of this study is to assess whether Chinese children with high apnea–hypopnea index (AHI) are sleepier by a modified Epworth Sleepiness Scale (ESS). Materials and methods  Records were retrospectively reviewed. We included children who were between 3 and 12 years old, admitted for overnight polysomnogram because of suspected obstructive sleep apnea syndrome (OSAS). A modified ESS was used to assess excessive daytime sleepiness (EDS) of the children. Results  One hundred ninety-two Chinese children were included. Children with high AHI, defined as AHI > 5.0, were sleepier than children with AHI less than or equal to 5. After adjustment by age, gender, and obesity, children with high AHI remained significantly sleepier. Modified ESS was significantly correlated with AHI (rho = 0.124, 95% CI = 0.004–0.281). Modified ESS score of >8 was the best cutoff point with the sensitivity and specificity of 0.29 and 0.91, respectively. The odds ratio of children with modified ESS > 10 having high AHI was 4.231 (95%CI = 1.248 to 14.338) and children with modified ESS > 8 had the highest odds ratio, 4.295(95%CI = 1.66 to 11.1), of having high AHI. Conclusion   Chinese children with high AHI appear to be sleepier than children with low AHI. Children with suspected OSAS and high modified ESS, i.e., ESS > 8, had significantly higher odds ratio of having high AHI. Increased sleepiness is a specific but not a sensitive symptom in snoring children with high AHI. Screening for EDS in snoring children may help us identify those with high AHI and prioritize the management of those children. All authors worked and the study was carried out in Kwong Wah Hospital in Hong Kong. There was no conflict of interest and no specific source of funding for the study.
