血管生成素样蛋白与胰岛素抵抗和糖代谢的关系及在多囊卵巢综合征中的作用

多囊卵巢综合征（polycystic ovary syndrome,PCOS）是育龄期女性最常见的内分泌及代谢性疾病之一,PCOS患者发生心血管疾病和2型糖尿病的风险增加。越来越多的研究支持胰岛素抵抗（insulin resistance,IR）是PCOS重要的病理机制之一。血管生成素样蛋白（angiopoietin-like proteins,ANGPTLs）家族是一类与血管生成素结构相似的分泌型糖蛋白,目前已发现8个成员,即ANGPTL1~ANGPTL8。ANGPTLs在PCOS患者血液中表达水平升高,并且与IR程度密切相关,ANGPTLs通过促进脂肪组织炎症、调节胰岛素分泌及磷脂酰肌醇3激酶/蛋白激酶B（PI3K/Akt）信号通路等参与了IR和糖代谢,这很可能与PCOS的发病有关。综述ANGPTLs参与IR和糖代谢的机制及其在PCOS中的作用,以期进一步探讨ANGPTLs参与PCOS发病的机制,为预测和治疗PCOS提供新思路。     

农村老年人老化期望现状及影响因素研究

目的 了解农村老年人的老化期望现状，分析其影响因素，为针对干预提供参考。 方法 采用一般资料调查表、UCLA孤独感量表简化版、老化期望量表、简版自我感知老化量表对199名农村老年人进行问卷调查。 结果 老化期望总分为32.72±9.18，孤独感得分为15.11±3.82，自我感知老化得分为52.75±2.76；多元线性回归分析显示，性别、婚姻状况、患慢性病种数、独居、孤独感、自我感知老化及经济来源是农村老年人老化期望的影响因素（调整R2=0.612，均P＜0.05）。 结论 农村老年人的老化期望水平较低，女性、孤独、无配偶、患慢性病较多、老化态度消极及低收入人群是关注的重点。     

主动脉出口血压对左心室血流特性的影响

采用Mimics对心脏进行三维重构，用3-matic进行模型优化以及模型误差分析，对左心室室壁运动做速度分布假设，基于UDF宏文件对左心室室壁运动编写程序，将血液视为非牛顿流体，采用动网格技术研究不同血压对左心室血液流动的影响。模拟发现当左心室收缩时，压力梯度明显，内部压力减小。当左心室舒张时，内部压力逐渐增高。二尖瓣口处的速率先增大后减小。血压升高，左心室内剪切应力持续增大，极易破坏红细胞结构，产生溶血现象，导致心脏功能紊乱。     

Effect and Safety of Tongyan Spray (通咽喷雾剂) on Hyoid Motion in Patients with Dysphagia after Ischemic Stroke

Objective: To observe the effects and safety of Tongyan Spray (通咽喷雾剂) on the range and time of hyoid motion in patients with ischemic post-stroke dysphagia. Methods: Seventy-two patients with ischemic post-stroke dysphagia were selected and randomly assigned to a treatment group (36 cases) and a control group (36 cases) by a random number table from January 2013 to October 2014. All patients swallowed 4 kinds of barium meals with different traits respectively, and each patient underwent video fluoroscopy (VF) examination twice. In the treatment group, Tongyan Spray was sprayed to the pharynx on both sides and the middle part once respectively. The spray was applied 30 min before the second examination. Purified water at room temperature was used as placebo in the control group. The changes in the range and time of hyoid motion in both groups were observed before and after treatment. Results: Six patients dropped out in each group, and 60 patients completed the study and were included in the final analysis. Significant improvement was observed in the range of superior hyoid excursion distance and the time of hyoid motion in the treatment group compared with the control group (P<0.05). There were no obvious adverse reactions observed in oral mucosa in both groups during the whole study. Conclusion: Tongyan Spray was an effective and safe medicine for improving swallowing function in patients with ischemic post-stroke dysphagia.     

血清淀粉样蛋白A联合神经元特异性烯醇化酶对脑出血的诊断价值

目的探讨血清淀粉样蛋白A(serum amyloid A,SAA)联合神经元特异性烯醇化酶(neuron-specific enolase,NSE)对诊断脑出血的临床价值。方法选取2018-03—2020-03郑州大学第二附属医院80例脑出血患者为观察组,其中轻度组40例,重度组40例;另外选取同期40例健康体检者为对照组。应用ROC曲线对血清淀粉样蛋白A联合NSE检测对脑出血的诊断价值进行分析。结果重度组血清中SAA、NSE水平均高于轻度组和对照组(P<0.05);联合检测的灵敏度、特异度高于SAA或NSE单独检测。结论SAA联合NSE对脑出血患者的早期诊断、临床干预具有重要意义。     

Huayu Pill (化瘀丸) Promotes Fluorescent Doxorubicin Delivery to Tumors in Mouse Model of Lung Cancer

Objective: To study the effect and mechanism of Huayu Wan (化瘀丸, HYW) in combination of chemotherapy of tumor treatment. Methods: HYW serum was added in Lewis cells to assess its impact on fluorescent doxorubicin delivery in vitro. Then, Lewis tumor cells was implanted in C57BL/6 mice via xenograft transplantation. Tumor growth was measured and signal intensity corresponding to blood flow was assessed by laser doppler perfusion imaging (LDPI). Finally, the effect of HYW on the efficacy of doxorubicin was studied. Results: HYW can improve the transfer of fluorescent doxorubicin into cells. The blood flow signal in the tumor tissues of the HYW group was higher than that of the control group (P<0.01). Furthermore, HYW improved drug delivery of doxorubicin to tumor tissues, and this activity was associated with HYW-induced microvascular proliferation (P<0.01). Conclusions: HYW can promote microangiogenesis and increase blood supply in tumor tissues, which in turn may increase the risk of metastasis. At the same time, HYW increases drug delivery and improves the efficacy of chemotherapy drugs through vascular proliferation. Therefore, rational judgment must be exercised when considering applying HYW to an antitumor regimen.
