正常与缺血性心肌梗死及心肌肥厚大鼠超声心动图参数变化趋势比较

目的 通过对正常和心血管疾病状态下的大鼠进行连续超声心动图检测,获得客观准确的大鼠心脏超声参数的变化趋势。方法 建立缺血性心肌梗死和压力负荷增高诱导心肌肥厚的大鼠模型,分别在术前、术后1、2和4周进行超声心动图检测,在相同时间点对正常大鼠进行超声心动图检测,并记录超声参数数据。结果 正常大鼠各心脏参数随时间的变化均有所升高,属正常生长状态。心肌梗死大鼠心脏变化以心室重构和功能障碍为主,心室内径和心室容积随时间变化显著增加,射血分数和短轴缩短率显著降低,差异均有统计学意义（P＜0.05）。心肌肥厚大鼠心脏变化以形态改变为主,左室前、后壁厚度随着时间的延长显著增加,收缩末期容积显著下降,射血分数和短轴缩短率代偿性升高,差异均有统计学意义（P＜0.05）。结论 应用超声心动图可获得正常和疾病状态下较为客观准确的大鼠心脏超声数据,为后续应用大鼠实验模型研究各种心血管疾病提供了数据参考。     

伴有面转代偿头位的先天性下直肌麻痹临床特征与手术治疗

目的：描述伴有面转代偿头位的先天性单纯下直肌麻痹患者的临床表现,并分析其手术治疗效果。

方法：回顾性分析2014-05/2018-07伴有明显面转代偿头位的先天性下直肌麻痹患者,手术前后患者面转程度的变化借助骨科量角器来检查,垂直、水平斜视度变化通过三棱镜交替遮盖试验来测量,旋转斜视度变化通过眼底对眼球客观旋转状态评估。下直肌缩短术是主要治疗方案。

结果：在15例研究对象中,有13例行下直肌缩短术或者联合上直肌后徙术术后疗效好,下直肌运动不足明显改善,眼球运动协调,以面转为主的代偿头位消失,垂直、水平、旋转斜视得到矫正; 并得出：每缩短1 mm下直肌可矫正1.54±0.93°内旋斜视。而行下斜肌断腱术治疗的垂直斜视度小的患者,面转改善不理想,仍遗留眼球运动不协调。

结论：先天性单纯的下直肌麻痹以面转代偿头位为主,下直肌缩短术治疗效果好,轻度的过矫及欠矫不影响手术疗效。

The attenuation effect of potassium 2‐(1‐hydroxypentyl)‐benzoate in a mouse model of diabetes‐associated cognitive decline: The protein expression in the brain

Aims dl‐PHPB (potassium 2‐(1‐hydroxypentyl)‐benzoate) has been shown to have neuroprotective effects against acute cerebral ischemia, vascular dementia, and Alzheimer''s disease. The aim of this study was to investigate the effects of dl‐PHPB on memory deficits and preliminarily explore the underlying molecular mechanism.MethodsBlood glucose and behavioral performance were evaluated in the KK‐A^y diabetic mouse model before and after dl‐PHPB administration. Two‐dimensional difference gel electrophoresis (2D‐DIGE)‐based proteomics was used to identify differentially expressed proteins in brain tissue. Western blotting was used to study the molecular mechanism of the related signaling pathways.ResultsThree‐month‐old KK‐A^y mice were given 150 mg/kg dl‐PHPB by oral gavage for 2 months, which produced no effect on the level of serum glucose. In the Morris water maze test, KK‐A^y mice treated with dl‐PHPB showed significant improvements in spatial learning and memory deficits compared with vehicle‐treated KK‐A^y mice. Additionally, we performed 2D‐DIGE to compare brain proteomes of 5‐month KK‐A^y mice treated with and without dl‐PHPB. We found 14 altered proteins in the cortex and 11 in the hippocampus; two of the 25 altered proteins and another four proteins that were identified in a previous study on KK‐A^y mice were then validated by western blot to further confirm whether dl‐PHPB can reverse the expression levels of these proteins. The phosphoinositide 3‐kinase/protein kinase B/glycogen synthase kinase‐3β (PI3K/Akt/GSK‐3β) signaling pathway was also changed in KK‐A^y mice and dl‐PHPB treatment could reverse it.ConclusionsThese results indicate that dl‐PHPB may play a potential role in diabetes‐associated cognitive impairment through PI3K/Akt/GSK‐3β signaling pathway and the differentially expressed proteins may become putative therapeutic targets.

Use of the optimized sodium thiosulfate regimen for the treatment of calciphylaxis in Chinese patients

BackgroundSodium thiosulfate (STS) can be used to treat patients diagnosed with calciphylaxis, which is a rare life-threatening syndrome. However, our patients treated with the recommended STS regimen presented with serious adverse events, resulting in treatment withdrawal. Then an optimized STS regimen was used to increase the tolerance of patients to STS and improve treatment continuation. The curative effect of the new regimen is not yet definite. Therefore, this study aimed to evaluate the response to the use of the optimized STS regimen for the treatment of calciphylaxis in Chinese patients during the first three courses of treatment.MethodsDemographic, clinical, and laboratory data were retrospectively collected on 31 calciphylaxis patients with chronic kidney disease (CKD) or end-stage kidney disease (ESKD) treated with the optimized STS regimen. The primary outcome was a clinical improvement. The secondary outcomes included survival rate and adverse events.ResultsTwenty-five patients (over 80%) achieved clinical improvement considering improvement or nonspecific changes of skin lesions (80.65%) and pain relief (100%). Furthermore, 54.84% of patients did not experience any adverse events and none died from complications. During a median follow-up of 9 months (interquartile range 4‒19), 27 patients (87.10%) survived; additionally, 13 patients (41.94%) survived after a one-year follow-up period.ConclusionThe optimized STS regimen is relatively safe, associated with satisfactory outcomes, and well tolerated by patients for short to medium treatment duration. Hence, it is a promising approach for the treatment of patients diagnosed with calciphylaxis.
