Ultrasonic vocalizations and maternal-infant interactions in a rat model of fetal alcohol syndrome

When isolated from their dams and littermates, rat pups emit ultrasonic vocalizations to elicit attention and retrieval from their dams. This study examined the effects of perinatal alcohol exposure on ultrasonic vocalizations and maternal-infant interactions. Alcohol was administered throughout gestation to the dams and during the early postnatal period to the pups. Control groups consisted of a nontreated control and an intubated, pair-fed control. Ultrasonic vocalizations were measured on postnatal day (PD) 5 under varying conditions of isolation. Maternal behaviors were examined on PD2, 4, 6, 8, and 10. Maternal behaviors were not significantly affected by prior alcohol administration to either the dams or the pups. However, ethanol-exposed rat pups vocalized more on PD5 than controls regardless of condition. The heightened vocalization response of the ethanol-exposed pups might be an underlying factor in the persistent effects of perinatal ethanol exposure on social behavior.     

A multi-systemic disease (lupus-like) preceding bronchioloalveolar carcinoma

Summary A patient with a multi-systemic disease (lupus-like) that preceded the onset of a bronchioloalveolar carcinoma is described, and a brief review of the literature is presented. We suggest that this tumor be listed among the neoplasms responsible for multi-systemic diseases with lupus-like characteristics.     

群体辨证论治的传承创新与现实意义

目的：纠正对辨证论治的理解偏差,全面精准应用该体系指导临床诊疗实践。方法：通过回顾辨证论治形成与发展的历史脉络,分析人们对辨证论治体系认识局限性原因,找到正确应用的路径。结果：辨证论治从古至今都包含整体与个体二个方面,可现在大家只强调其个体辨证论治的一面,忽略了群体辨证论治的临床应用。结论：完整的辨证论治体系包含个体辨证论治和群体辨证论治二个方面,二者同等重要,不可偏废。随着大数据时代和循证医学的推进,中医群体辨证论治理论具有更加突出的临床现实指导意义。     

Diarrhea Predominant-Irritable Bowel Syndrome (IBS-D): Effects of Different Nutritional Patterns on Intestinal Dysbiosis and Symptoms

Irritable Bowel Syndrome (IBS) is a chronic functional gastrointestinal disorder characterized by abdominal pain associated with defecation or a change in bowel habits. Gut microbiota, which acts as a real organ with well-defined functions, is in a mutualistic relationship with the host, harvesting additional energy and nutrients from the diet and protecting the host from pathogens; specific alterations in its composition seem to play a crucial role in IBS pathophysiology. It is well known that diet can significantly modulate the intestinal microbiota profile but it is less known how different nutritional approach effective in IBS patients, such as the low-FODMAP diet, could be responsible of intestinal microbiota changes, thus influencing the presence of gastrointestinal (GI) symptoms. The aim of this review was to explore the effects of different nutritional protocols (e.g., traditional nutritional advice, low-FODMAP diet, gluten-free diet, etc.) on IBS-D symptoms and on intestinal microbiota variations in both IBS-D patients and healthy subjects. To date, an ideal nutritional protocol does not exist for IBS-D patients but it seems crucial to consider the effect of the different nutritional approaches on the intestinal microbiota composition to better define an efficient strategy to manage this functional disorder.     

中枢性疲劳症候群临床与血清色氨酸的研究

目的：对珠海市中学生中枢性疲劳症候群的临床,患病率及与血清色氨酸的关系进行研究。方法：采用单纯随机抽样和整群一级抽样方法,对4年中学1594人进行问卷调查作为初筛,筛出有症状的部分人在医院进行以排除其它疾病为 的精查,并做血清色氨酸含量的测量,结果：临床表现自主神经症状,睡眠障碍,精神症状,推测珠海市中学生中患病率为11％,血清色氨酸含量较正常对照组低,两组有显著差异（P＜0．01）,结论：中枢性疲劳症候群是珠海地区中学生中的常见病,应积极于以防治;血中色氨酸含量的测定对诊断该疾病有一定的价值。     

术前孤立性CRP升高与体外循环术后并发症的相关性

目的探讨无感染的、术前孤立性C-反应蛋白(CRP)增加,对于体外循环心脏术后的结果,是否有预测性价值。方法分术前孤立性CRP升高(10.5～70.2mg／L)50例(A组)与CRP正常(＜10mg／L)50例对照(B组),B组匹配A组在年龄、性别和疾病种类,两组均进行体外循环心脏手术。结果A组脓毒性并发症(20％)比对照组(2％)多(P＜0.01)。这些病人微生物学阳性仅10％。A组中需要儿茶酚胺支持的占28％,而B组仅12％(P＜0.05)。A组较B组术后需呼吸机支持的时间明显延长(25.2±6.2h比6.6±0.5h)(P＜0.01)、ICU滞留时间也较B组长(4.6±0.8d比2.6±0.3d)(P＜0.05)。结论术前孤立性CRP升高的病人,体外循环术后,发生脓毒性并发症的可能性明显增加。且大多数病例微生物学实验阴性,推测大多数脓毒性并发症是由于全身炎症反应综合征的原因。     

益气止血药对脾不统血证模型动物前列腺素的作用

采用复合因素的脾不统血证大鼠模型 ,以 6 酮 前列腺素F1α(6 酮 PGF1α)和血栓素B2(TXB2 )作为观测指标 ,对益气止血药对脾不统血证模型大鼠血浆和子宫前列腺素的影响进行了研究。结果 :大剂量组益气止血药能降低脾不统血证模型血浆和子宫的 6 酮 PGF1α及子宫 6 酮 PGF1α/TXB2 比值。说明 6 酮 PGF1α及 6 酮 PGF1α/TXB2 比值升高可能是脾不统血证的重要机理之一。
