Dendritic fibromyxolipoma in the latissimus dorsi: a case report and review of the literature

Dendritic fibromyxolipoma is an uncommon benign soft tissue tumor. Here, we report a case in a 53-year-old man presenting a painless mass located deep in the latissimus dorsi of the right back. Microscopically, the tumor was mainly consisted of small spindle and stellate cells, abundant myxoid stroma, collagen bundles and mature adipose tissue. Immunohistochemical study showed the spindle and stellate cells were positive for CD34, Bcl-2 and Vimentim, but not for Keratin, EMA, SMA and Desmin. To date, one year after operation, the patient is well without evidence of recurrence or metastasis. The implication of this report is to provide insights into further understanding of this rare tumor with review of the literature.

定量组织速度成像对家兔肺动脉栓塞模型的动态观察

目的 评价定量组织速度成像技术对检测家兔肺动脉栓塞模型右室功能的应用价值。方法 家兔22只, 经耳缘静脉注入栓子制成急性肺动脉栓塞模型。分别于造模前、造模后即刻、造模后1周及3周观察家兔右心室动态变化情况。存储心尖四腔心切面定量组织速度成像(QTVI)图像并进行脱机分析。结果 造模后即刻, 右室游离壁基底段, 中间段的收缩期峰值速度(V_P)均较造模前明显减低, 达峰时间(T_Vp)延长, 三尖瓣口舒张早期峰值血流速度/舒张晚期峰值血流速度(Ve/Va)大于1。差别具有显著性意义(P<0.05)。造模后1周, 右室游离壁基底段, 中间段的收缩期峰值速度(V_P)均较造模前减低, 达峰时间(T_Vp)延长, 较造模后即刻组差别无显著性意义, 但Ve/Va小于1。造模后3周, 右室游离壁基底段, 中间段的收缩期峰值速度(V_P)较造模前仍减低, Ve/Va比值小于1。较造模后1周组差别具有显著性意义(P<0.05)。组内比较收缩期峰值速度, 右室游离壁基底段均较中间段增大, 差别具有显著性意义。但收缩期达峰时间, 两者差别无显著性意义。结论 定量组织速度成像能够直观反映家兔右室舒张及收缩功能状况,是评价动物肺动脉栓塞模型右室功能的重要手段。     

Serum cholesterol as a predictor of mortality among the elderly patients with pneumonia in the emergency department

BackgroundReduced cholesterol levels are associated with poor outcomes in critically ill patients. However, the effect of reduced cholesterol levels on the prognosis of patients with community-acquired pneumonia (CAP) is unclear. This study aimed to investigate the association between serum total cholesterol levels and the clinical outcomes of elderly patients with CAP.MethodsThis was a retrospective observational study that included elderly (≥65 years) CAP patients hospitalized through emergency department between January 2016 and December 2019. We collected their baseline characteristics and laboratory data, including total cholesterol levels at the time of admission. Univariate and multivariate analyses were performed to determine the association between total cholesterol levels and 14-day in-hospital mortality.ResultsA total of 380 patients were included. The overall 14-day in-hospital mortality rate was 12.37%. Survivors had higher total cholesterol levels than non-survivors (median, 125 mg/dL; interquartile range [IQR], 102–151 mg/dL versus median, 100 mg/dL; IQR, 83–126 mg/dL; p < 0.001). Multivariate analysis using a logistic regression model showed that a total cholesterol level of <97 mg/dL was independently associated with 14-day in-hospital mortality in patients with CAP (odds ratio, 2.93; 95% confidence interval, 1.13–7.599; p = 0.027).ConclusionsA decreased level of total cholesterol was associated with increased short-term mortality in elderly patients with CAP. Initial total cholesterol levels may be a useful biomarker to predict the outcome of patients with CAP.     

导滞排石方对单纯性肾阳性结石患者24h尿THP及尿钙水平影响的研究

目的：观察复方导滞排石方对单纯性肾阳性结石患者24 h尿THP（Tamm-Horsfall蛋白）及尿钙水平的影响。方法：120例单纯性肾阳性结石患者采用区组随机观察化方法分配到G1组、G2组、G3组和G4组。所有入选患者均在充分术前准备的情况下根据结石实际情况施行体外冲击波碎石（ESWL）或经皮肾镜下气压弹道碎石术或二者结合治疗。术后G4组按西医常规治疗,其它3组则在西医常规治疗的基础上配合口服导滞排石方。G1组每天3次,每次200 mL温服;G2组每天2次,每次200 mL温服;G3组每天1次,每次200 mL温服。用药7 d为1个疗程,共4个疗程。所有患者分别于术后第1天、第5天、第7天按《外科术后康复评价量表》进行评分,并运用双抗体夹心酶联免疫吸附法（ELISA）及全自动生化分析仪对所有患者治疗前后的24 h尿THP及尿钙进行测定。结果：治疗前4组间基线特征均衡性良好（P〉0.05）;治疗后G1、G2和G3组中所有患者24 h尿THP水平显著升高,尿钙水平明显下降,其中G1组效果最佳（P〈0.05）;而G4组中所有患者治疗前后24 h尿THP及尿钙水平变化不大（P〉0.05）。治疗后所有患者按《外科术后康复评价量表》进行评分,发现G1组中患者外科术后康复评分情况要明显优于其他3组（P〈0.05）。结论：复方导滞排石方不仅能够显著影响患者24 h尿THP（Tamm-Horsfall蛋白）及尿钙水平,还可提高患者术后康复评分,改善症状,促进术后恢复。
