理气中药组方对糖尿病大鼠胃排空延迟的作用

目的:观察理气中药经验组方对糖尿病大鼠胃排空延迟的干预作用。方法:雌雄各半成年SD大鼠110只,随机分为正常组(A组)、糖尿病中药组(B组)、糖尿病胃复安组(C组)、糖尿病组(D组)。A组、D组1次/d按10 mL/只予0.9%生理盐水灌胃,B组1次/d按8 mL/只予中药煎剂灌胃,C组1次/d按0.5 mg/只予胃复安片灌胃。喂养12周后,行13C胃排空实验及甲基橙水溶液胃排空实验,观察各组大鼠胃排空情况。结果:糖尿病大鼠胃排空较正常大鼠明显延迟(P0.01),糖尿病大鼠胃排空延迟模型制作成功。糖尿病中药组和糖尿病胃复安组大鼠胃排空较糖尿病组快(P0.01);糖尿病中药组大鼠胃排空较糖尿病胃复安组大鼠快(P0.05)。结论:常规喂养12周后糖尿病大鼠出现胃排空延迟。理气中药陈皮、枳实、木香、香附组方煎剂和胃复安均能促进糖尿病大鼠胃排空,理气中药组方煎剂的效果优于胃复安。     

Cardiac Denervation for Arrhythmia Treatment with Transesophageal Ultrasonic Strategy in Canine Models

Stellate ganglion (SG) modification has been investigated for arrhythmia treatment. In this study, transesophageal SG imaging and intervention were explored using a homemade 30F integrated focused ultrasonic catheter in healthy mongrel canines in vivo. Anatomic details of SGs were ultrasonically imaged and evaluated. SG had a heterogeneous echoic structure and characteristic profiles sketched by hyper-echoic outlines in an ultrasonogram. Left SGs in the experimental group were successfully ablated through the esophagus under ultrasonic guidance provided by the catheter itself. Two weeks after the ablation, the QT and QTc of the experimental group decreased compared with those of the sham group and at baseline (both p values < 0.001). Histologic examination revealed that left SGs were destroyed. No major complications were observed. This approach may be further explored as a method for ganglia remodeling evaluation and as a strategy of ganglia modification for arrhythmia and for other diseases.     

健康支持性环境对四川农村人群的不同血压水平的影响分析

目的 探讨健康支持性环境中的不同特征变量对四川省农村人群的不同血压水平的影响。方法 采用多阶段整群抽样的方法，随机抽取四川省7个县（区）8400名的18岁以上常住居民为调查对象。问卷调查一般人口学特征、身体活动行为特征和环境等信息。采用标准方法测量身高、体重、腰围和血压。采用无序多分类logistic回归分析。结果 本调查人群中共检出正常高值血压者4270例，检出率为50.83%，标化率为37.02%，平均年龄（56.22±14.89）岁；高血压患者1498例，检出率为17.83%，标化率为7.92%，平均年龄（65.26±11.28）岁。无序多分类logistic回归结果显示，住宿环境好、获得运动方面的健康信息和参与中等强度活动150Symbol~A@300min/周是正常高值血压和高血压人群的共同保护因素；住宿便利（OR=0.789, 95%CI:0.649~0.958, P=0.017）、医疗服务可及性便利（OR=0.686, 95%CI:0.509~0.924, P=0.013）、对健身步道和健身广场满意为高血压人群的保护因素。结论 多途径合理构建健康支持性环境，对农村正常高值血压者和高血压患者具有保护作用，对遏制农村高血压的流行现状起到一定作用。     

补阳还五汤加伸筋草治疗脑梗死后痉挛型偏瘫疗效研究

目的:探讨补阳还五汤重用伸筋草治疗脑梗死后痉挛型偏瘫的作用。方法:收集脑梗死后痉挛型偏瘫患者共88例,分为两组,对照组44例,西医治疗加康复训练和补阳还五汤治疗; 研究组44例,西医治疗加康复训练及补阳还五汤重用伸筋草治疗。比较治疗前后患者患侧上下肢肌张力、临床疗效、NIHSS、日常生活能力Barthel指数以及上下肢运动功能和不良反应发生率。结果:治疗后,两组患者患侧上下肢肌张力≤1级者占比均升高,且研究组中≤1级者占比均高于对照组,组间比较有统计学意义(P<0.05)。两组临床疗效等级分布和总有效率比较,差异有统计学意义(P<0.05)。治疗后两组患者NIHSS评分均降低,且研究组NIHSS评分低于对照组,治疗后两组患者Barthel指数和患侧上下肢FMA评分均升高,且研究组均高于对照组,组间比较有统计学意义(P<0.05)。两组不良反应发生率比较,差异无统计学意义(P>0.05)。结论:补阳还五汤重用伸筋草能够显著降低患者患侧上下肢肌张力,改善临床疗效和神经功能缺损,提高患者日常生活能力和患侧运动功能,且安全性良好。     

乳腺弥漫大B细胞淋巴瘤临床特点及预后分析

目的:探讨乳腺弥漫大B细胞淋巴瘤（DLBCL）患者的临床特征及预后。方法:回顾性分析2014年5月起至2018年12月我院收治的18例乳腺DLBCL患者的临床特点及预后。结果:在18例患者中，17例为女性，中位年龄为57岁，病变主要累及右侧乳腺（11/18，61.1%）。将其分为原发性乳腺DLBCL（PB-DLBCL）和继发性乳腺DLBCL（SB-DLBCL）两大类。11例（57.6%）PB-DLBCL与7例（42.4%）SB-DLBCL相比，其具有Ann Arbor分期多为Ⅰ-Ⅱ期（P＜0.01）、B症状少（P=0.013）、相对更高的白细胞计数（P=0.041）、骨髓未累及（P=0.043）、完全缓解（CR）率高（P=0.049）等特点。生存分析发现PB-DLBCL患者5年总生存期（OS）显著长于SB-DLBCL患者（P=0.013）。本研究以非生发中心B细胞型（non-GCB）居多，生发中心型（GCB）与non-GCB型之间OS无显著差异（P=0.885）。所有获得CR患者的生存期均显著延长（P=0.008）。结论:乳腺DLBCL多见于中年女性，以右侧乳腺肿块为主要临床表现，分子分型多为non-GCB型。与SB-DLBCL患者相比，PB-DLBCL患者具有Ann Arbor分期早、B症状少、相对更高的白细胞计数、骨髓未累及、CR率高等特点，并且生存期显著延长。无论是PB-DLBCL和SB-DLBCL，还是GCB型和non-GCB型，获得CR提示预后良好。     

Elevated serum levels of Interleukin‐37 are associated with inflammatory cytokines and disease activity in rheumatoid arthritis

Interleukin‐37 (IL‐37) is closely associated with several inflammatory diseases. However, the role of IL‐37 in the pathogenesis of rheumatoid arthritis (RA) remains unclear. The aim of this study was to assess the associations between serum levels of IL‐37 and disease activity, inflammatory cytokines, and bone loss in patients with RA. Serum cytokines levels were examined by Enzyme‐linked immunosorbent assay (ELISA). Radiographic bone erosion was assessed using the van der Heijde‐modified Sharp score and bone mineral density (BMD) was measured using DXA. Serum IL‐37 levels in RA patients were significantly higher than those in HCs (p < 0.001), and were significantly positively correlated with clinical parameters of disease activity and serum levels of IL‐17 and IL‐23. In addition, serum IL‐37 levels were significantly higher in patients with stage IV of radiographic bone erosion than those with stage III and stage I–II, and they were significantly higher in those with osteopenia and osteoporosis than in those with normal BMD. Our results suggest that serum IL‐37 levels were increased in patients with RA and were positively associated with disease activity, IL‐17/IL‐23 and bone loss in RA, suggesting that IL‐37 may play a critical role in the pathogenesis of RA.
