Postoperative development of sarcopenia is a strong predictor of a poor prognosis in patients with adenocarcinoma of the esophagogastric junction and upper gastric cancer

Background

There were few studies assessed the postoperative sarcopenia in patients with cancers. The objective of present study was to assess whether postoperative development of sarcopenia could predict a poor prognosis in patients with adenocarcinoma of esophagogastric junction, (AEG) and upper gastric cancer (UGC).

隐性心肌缺血者血脂及血液流变学指标的检测及意义

目的:观察隐性心肌缺血者血脂及血液流变指标的变化,为早期发现和防治冠心病提供实验室依据。方法:选择性别和年龄大致相同的隐性心肌缺血者和心电图正常的健康对照人群,同时进行血脂和血液流变学指标检测,比较两组两类指标的差异。结果:隐性心肌缺血者的总胆固醇、甘油三酯和血液低、中、高切粘度及红细胞聚集指数、变形指数均明显高于正常对照组,每项指标的异常率在两组间相差明显。结论::血脂和血液流变学检测结果可作为隐性心肌缺血和冠心病早期诊断的实验室指标。     

无症状心肌缺血心率变异性分析

目的:探讨无症状心肌缺血的昼夜节律变化与心脏自主神经的关系。方法:对无症状心肌缺血者及健康者均进行24小时动态心电监护,从而分析其心率变异性(HRV)。结果:无症状心肌缺血组的HRV较正常对照组的HRV明显下降(P<0.05);无症状心肌缺血组其白天的HRV较夜间下降更低,存在明显的昼夜节律变化(P<0.05)。结论:无症状心肌缺血的发生与交感神经活性增强、迷走神经活性减低有关,自主神经受损是无症状心肌缺血的一个重要因素。

目的:探讨川芎嗪、丹参、银杏达莫注射液组合治疗糖尿病性微量白蛋白尿的疗效.方法:75例住院治疗的2型糖尿病患者随机分成丹参组(n=35)和银杏组(n=45),分别接受川芎嗪注射液160 mg 丹参注射液20 mL和川芎嗪注射液160mg 银杏达莫注射液20 mL,每日静滴1次,连续14日的治疗.在治疗前、后采集血、尿标本,测定血糖各项、血脂各项、肾功能和尿微量白蛋白等,并进行统计学分析处理.结果:治疗前,丹参组的甘油三脂和胆固醇脂较银杏组显著地升高(均P＜0.05),年龄、病程、血压、BMI、血糖各项、肾功能和尿微量白蛋白排泄量等指标,组间比较无显著性差异;治疗后,丹参组与银杏组的血糖均显著下降(均P＜0.01),丹参组的尿微量白蛋白排泄量未减少,银杏组的则显著的减少(P＜0.01),组间比较有显著性差异(P＜0.01).结论:川芎嗪与丹参注射液可能组合不当,不能减少尿微量白蛋白排泄量,川芎嗪与银杏达莫注射液组合能显著地减少尿微量白蛋白排泄量.     

Experimental Referred Pain Extends Toward Previously Injured Location: An Explorative Study

Facilitated pain mechanisms have been demonstrated in musculoskeletal pain, but it is unclear whether a recent painful injury leaves the pain system sensitized. Pain characteristics were assessed in individuals who recently recovered from ankle pain (recovered pain group; n?=?25) and sex-matched control subjects (n?=?25) in response to tonic pressure pain and saline-induced pain applied at the shin muscle. Pain intensity and pain referral patterns were recorded bilaterally after the painful muscle stimulus. Pressure pain thresholds were measured at the lower legs and shoulder. Cuff pressure algometry on the lower leg was used to assess pain detection threshold, pressure evoking 6-cm pain score on a 10-cm visual analog scale, pain tolerance, temporal summation of pain, and conditioned pain modulation. Compared with in control subjects, saline-induced and pressure-induced pain in the shin muscle were more frequently felt as referred pain in the previously painful ankle (P < .05), and the pain area within the previously affected ankle was larger after saline-induced pain (P < .05). In the recovered pain group, conditioned pain modulation responses and the cuff pressure needed to reach a 6-cm pain score on a 10-cm visual analog scale was higher in the previously painful leg compared with in the contralateral leg (P < .05). No group differences were found in pressure pain threshold, pain detection threshold, pain tolerance, and temporal summation of pain.

Identification and characterization of SMI32-immunoreactive amacrine cells in the mouse retina

Mammalian neurons express the neural intermediate filament protein neurofilament (NF). In the retina, NFs have been detected primarily in the axons and processes of retinal ganglion and horizontal cells. We found an amacrine cell type that was immunolabeled with an antibody against SMI32, a non-phosphorylated epitope on neurofilament proteins of high molecular weight, in the mouse retina. This type of amacrine cell was non-randomly distributed, and these cells exhibited a central-peripheral density gradient. Most of these cells co-expressed GABA and ChAT, but not glycine or any other amacrine cell marker. These results suggest that some SMI32-immunoreactive amacrine cells belong to a GABAergic population, and that SMI32 can therefore be used as a marker for a subset of amacrine cells in addition to ganglion cells and horizontal cells in the mouse retina.     

Arsenic methylation capacity is associated with breast cancer in northern Mexico

Exposure to environmental contaminants, dietary factors and lifestyles may explain worldwide different breast cancer (BC) incidence. Inorganic arsenic (iAs) in the drinking water is a concern in many regions, such as northern Mexico. Studies in several countries have associated the proportion of urinary monomethylarsenic (%MMA) with increased risks for many As-related diseases, including cancer. To investigate the potential relationships between the risk of BC and the capacity to methylate iAs, a hospital-based case–control study (1016 cases/1028 controls) was performed in northern Mexico. Women were directly interviewed about their reproductive histories. The profile of As metabolites in urine was determined by HPLC-ICP-MS and methylation capacity was assessed by metabolite percentages and indexes. Total urinary As, excluding arsenobetaine (TAs-AsB), ranged from 0.26 to 303.29 μg/L. Most women (86%) had TAs-AsB levels below As biological exposure index (35 μg/L). Women with higher %MMA and/or primary methylation index (PMI) had an increased BC risk (%MMA OR_Q5vs.Q1 = 2.63; 95%CI 1.89,3.66; p for trend < 0.001; PMI OR_Q5vs.Q1 = 1.90; 95%CI 1.39,2.59, p for trend < 0.001). In contrast, women with higher proportion of urinary dimethylarsenic (%DMA) and/or secondary methylation index (SMI) had a reduced BC risk (%DMA OR_Q5vs.Q1 = 0.63; 95%CI 0.45,0.87, p for trend 0.006; SMI OR_Q5vsQ1 = 0.42, 95%CI 0.31,0.59, p for trend < 0.001). Neither %iAs nor total methylation index was associated to BC risk. Inter-individual variations in iAs metabolism may play a role in BC carcinogenesis. Women with higher capacity to methylate iAs to MMA and/or a lower capacity to further methylate MMA to DMA were at higher BC risk.
