Persistent fifth aortic arch associated with 22q11.2 deletion syndrome.

BACKGROUND: Chromosome 22q11.2 deletion is frequently associated with conotruncal malformations and aortic arch anomalies. This study investigated the association of chromosome 22q11.2 deletion with clinical manifestations in four pediatric patients with persistent fifth aortic arch. METHODS: Four patients with persistent fifth aortic arch treated between July 1997 and June 2004 were included in this retrospective study. There were two girls and two boys, aged 2 days to 11.3 years, with persistent fifth aortic arch and cardiac conotruncal malformations. Chart recordings, plain chest films, two-dimensional and Doppler echocardiograms, cardiac catheterization with angiograms, surgical findings, and cytogenetic study were analyzed. RESULTS: Clinically, all four patients had the cardinal phenotypic features of 22q11.2 deletion syndrome, including cardiovascular malformations (conotruncal malformations and aortic arch anomalies), abnormal facies, thymic hypoplasia, canopy anomaly of the palate (high-arched palate, rather than cleft palate), and hypocalcemia (or hypoparathyroidism). All four patients were confirmed to have chromosome 22q11.2 deletion. CONCLUSION: Congenital conotruncal malformations, including tetralogy of Fallot with pulmonary atresia or stenosis, and aortic arch anomalies including a persistent fifth aortic arch or a right aortic arch, should lead to suspicion of chromosome 22q11.2 deletion when manifested together with any one of the other four cardinal phenotypic features.

我院2000-2004年医院感染革兰阴性杆菌耐药性趋势的研究

[目的]了解2000年～2004年院内感染革兰阴性杆菌分布及其耐药性。[方法]主要使用MicroScan-4微生物鉴定及药敏仪对2000年1月～2004年12月引起院内感染革兰阴性杆菌进行鉴定及药物敏感试验，结果录入Whonet5．3软件进行分析、统计。[结果]5年间，革兰阴性杆菌所致医院感染中，大肠埃希菌比例最高，在32．8％～38．1％之间，阴沟肠杆菌、不动杆菌比例呈上升趋势。细菌的耐药率在逐年上升，其中阴沟肠杆菌和鲍曼不动杆菌，耐药性高于其它革兰阴性杆菌（P〈0．05），对第三代头孢菌素耐药率分别达到60％～80％、40％～70％。对亚胺培南耐药的菌株日益增多。[结论]细菌的耐药性逐渐增强，阴沟肠杆菌、鲍曼不动杆菌成为非常重要的医院感染病原菌，医务工作者要重视医院感染，加强耐药性监测，合理使用抗生素。     

Relationship between Mandarin speech reception thresholds and pure-tone thresholds in the geriatric population.

BACKGROUND/PURPOSE: In the geriatric population, the reliability of pure-tone threshold (PTT) is sometimes poorer than that in young adults because of various reasons. This study assessed the relationship between Mandarin speech reception thresholds (SRTs) and PTTs in the aged and developed SRT as a measure for corroborating PTT. METHODS: This prospective study enrolled 46 consecutive subjects over 60 years of age. The results of SRT and PTT were collected from one ear randomly selected from each subject. Simple linear and multiple regressions were used to determine the correlation and linear regression coefficients between SRTs and PTTs at various frequencies. RESULTS: In the simple regression analysis, the correlation coefficient was highest at 1000 Hz (r = 0.949) and 500 Hz (r = 0.922), followed by 250 Hz (r = 0.850) and 2000 Hz (r = 0.792). In the multiple regression model with SRT as the dependent variable and PTTs as predictor variables, the resultant multiple correlation coefficient R was 0.967, while R2 was 0.936. In this model, PTTs at the frequencies of 500 Hz and 1000 Hz contributed significantly to the variance in SRTs with p values of 0.029 and < 0.001, respectively. These results demonstrated that the Mandarin SRT is strongly associated with PTTs at the frequencies of 500 Hz and 1000 Hz. CONCLUSION: This study established the agreement between Mandarin SRTs and PTTs in the low tone area of speech frequencies in the geriatric population. In clinical settings, SRT test can be rapidly and easily performed and is relatively inexpensive. It is a vital indicator of the accuracy of PTT measurement.     

The Influence of Intramammary Lipopolysaccharide Infusion on Serum Ca,P, Vitamin D,Cytokines and Cortisol Concentrations in Lactating Sows

Ten multiparous lactating sows were used to investigate whether intramammary infusion of lipopolysaccharides (LPS; Escherichia coli 0111:B4; 2.0 μg/kg of body weight) would affect the circulating concentrations of Ca, P, 25‐hydroxyvitamin D (25‐OHD), tumour necrosis factor‐α (TNF‐α), interleukin‐6 (IL‐6) and cortisol. The sows were randomly allotted to either control group (control) or LPS‐treated group with five individuals per group and were infused with either physiological saline solution or LPS solution. The rectal temperature and udder quarter appearance were recorded at 0 (just before infusion), 1, 3, 7, 12 or 24 h after infusion. Blood samples were taken at 0, 1, 3, 7, 12 or 24 h after infusion. Before infusion, the rectal temperatures of all sows were below 39.2°C. At 3 and 7 h after infusion, the sows in the LPS group had a rectal temperature over 39.4°C. At 24 h after infusion, the rectal temperatures returned to pre‐infusion levels. Serum Ca and P concentrations in the LPS group decreased (P < 0.05) after LPS infusion compared with the control group at 1 h after infusion. No significant differences (P > 0.05) in the concentrations of 25‐OHD were observed between groups control and LPS at any sampling time. Increased (P < 0.01) concentrations of serum TNF‐α, IL‐6 and cortisol were observed in the LPS group compared with the control group at 3 and 7 h after infusion respectively. In conclusion, the elevation of serum concentrations of TNF‐α, IL‐6 and cortisol and the alterations of circulating concentrations of Ca and P following LPS infusion indicate that the immune system has been activated and immune activation may affect macromineral homeostatic regulation, which might have important implications for metabolic health of lactating sows. Lowered serum Ca and P following immune activation also shows a causative mechanism whereby immune activation increases the risk of secondary disorders such as mastitis‐metritis‐agalactia syndrome. However, immune activation did not affect circulating concentrations of vitamin D metabolites.

谁抢了我的维生素

肤色晦暗不一定是皮肤需要做美容，吃饭时咬到舌头也不一定就是馋肉，诸如此类的现象，也许都是维生素缺失引起的。 维生素是维持正常生命活动所必需的小分子有机化合物，它既不供给能量，也不构成组织成分。在体内不能合成或合成甚微，而且必须由食物供给。 尽管需要量很少，但绝对不可或缺，它对物质代谢起着重要的调节作用。[编者按]
