Clinicopathological features,diagnosis, and treatment of sessile serrated adenoma/polyp with dysplasia/carcinoma

Sessile serrated adenoma/polyps (SSA/Ps) are early precursor lesions in the serrated neoplasia pathway, which results in BRAF‐mutated colorectal carcinomas with not only high levels of microsatellite instability but also microsatellite stable. SSA/Ps with advanced histology, including cytological dysplasia or minimally invasive carcinomas, are important lesions because SSA/Ps are considered major contributors to “interval cancers” and these lesions can rapidly become dysplastic or invasive carcinomas. Clinicopathologically, SSA/Ps with dysplasia or invasive carcinoma were associated with advanced age, female sex, and proximal colon. Although SSA/Ps with submucosal invasive carcinoma were smaller and invaded less deeply into the submucosal layer than conventional tubular adenomas with submucosal invasive carcinoma, SSA/Ps with submucosal invasive carcinoma frequently had a mucinous component and exhibited a higher potential for lymphatic invasion and lymph node metastasis. In an SSA/P series, endoscopic characteristics, including (semi)pedunculated morphology, double elevation, central depression, and reddishness, may help accurately diagnose SSA/Ps with advanced histology. Removal of SSA/Ps with dysplasia or invasive carcinoma was recommended. Endoscopic treatment such as endoscopic mucosal resection or endoscopic submucosal dissection is useful for those lesions. However, surgical resection with lymph node dissection might be indicated when SSA/Ps with invasive carcinoma are endoscopically suspected, because these have the high risk of lymph node metastasis. Greater awareness may promote further research into improving the detection, recognition, and complete resection rates of SSA/Ps with dysplasia or invasive carcinoma and reduce the interval cancer rates.     

Psychological characteristics and physiological reactivity to acute stress in mothers of children with autism spectrum disorder

Stress related to parenting a child with autism spectrum disorder can differently affect caregiver's physiological reactivity to acute stress. Here, parental stress levels, psychological characteristics, and coping strategies were assessed alongside measures of heart rate, heart rate variability, and cortisol during a psychosocial stress test in mothers of children with ASD (M‐ASD, n = 15) and mothers of typically developing children (n = 15). M‐ASD reported significantly higher levels of parental stress, anxiety, negative affectivity, social inhibition, and a larger preference for avoidance strategies. M‐ASD showed larger heart rate and cortisol responses to the psychosocial stress test. A positive relationship was found between parental stress levels and the magnitude of the cortisol stress response in both groups. The present findings indicate exaggerated physiological reactivity to acute psychosocial stress in M‐ASD and prompt further research to explore the role of individual differences in mediating the effects of parental stress on physiological stress responses.     

C.B‐17 SCID mice develop epicardial calcinosis with unaltered cardiac function

Inbred mouse strains are the most widely used mammalian model organism in biomedical research owing to ease of genetic manipulation and short lifespan; however, each inbred strain possesses a unique repertoire of deleterious homozygous alleles that can make a specific strain more susceptible to a particular disease. In the current study, we report dystrophic cardiac calcinosis (DCC) in C.B‐17 SCID male mice at 10 weeks of age with no significant change in cardiac function. Acquisition of DCC was characterized by myocardial injury, fibrosis, calcification, and necrosis of the tissue. At 10 weeks of age, 38% of the C.B‐17 SCID mice from two different commercial colonies exhibited significant calcinosis on the ventricular epicardium, predominantly on the right ventricle. The frequency of calcinosis was more than 50% for mice obtained from Taconic's Cambridge City colony and 25% for mice obtained from Taconic's German Town colony. Interestingly, the DCC phenotype did not affect cardiac function at 10 weeks of age. No differences in echocardiography or electrocardiography were observed between the calcinotic and non‐calcinotic mice from either colony. Our findings suggest that C.B‐17 SCID mice exhibit DCC as early as 10 weeks of age with no significant impact on cardiac function. This strain of mice should be cautiously considered for the study of cardiac physiology.     

自血穴位注射疗法联合马来酸茚达特罗治疗老年稳定期慢性阻塞性肺疾病的临床分析

目的探讨自血穴位注射疗法联合马来酸茚达特罗治疗老年稳定期慢性阻塞性肺疾病(COPD)的临床疗效及其对患者炎性因子、免疫功能及肺功能的影响。 方法将2015年5月至2016年5月我院收治的86例老年缓解期COPD患者分为观察组与对照组。对照组给予马来酸茚达特罗治疗，观察组在对照组治疗基础上另给予自血穴位注射疗法。治疗12周后，评价2组临床疗效。治疗前及治疗12周后，分别检测2组患者肺功能指标(FEV₁、FVC与PEF)，炎性因子(IL-8、α1-AT、IL-6及TNF-α)，免疫功能指标(IgG、IgA、CD3^＋及CD4^＋)水平。治疗期间，对2组患者的不良反应进行密切观察。 结果治疗后二组患者各项检测指标均优于治疗前。治疗12周后，观察组总有效率为90.7%，明显高于对照组的72.1%(P<0.05)。治疗12周后，观察组FEV₁、FVC与PEF等肺功能指标，IgG、IgA、CD3^＋及CD4^＋等免疫功能指标水平均明显高于对照组(P<0.05)，而IL-8、α1-AT、IL-6及TNF-α含量分别为(23.23±3.87)ng/L、(3.43±0.41)g/L、(52.25±5.38)ng/L及(43.12±3.98)ng/L，改善程度均明显优于对照组(P<0.05)。治疗期间，2组患者均未出现严重不良反应。 结论自血穴位注射疗法联合马来酸茚达特罗治疗老年稳定期COPD疗效确切，可有效改善患者炎症水平，值得进行深入研究。
