丁元庆从三阳论治痤疮经验

丁元庆认为痤疮属于阳证而好发于三阳经循行之处,三阳气机郁闭,郁而化热化火,火热内结是痤疮发病的病机关键,热结、瘀阻、滞毒于三阳经脉,外蒸而结于肌肤是痤疮的病理基础。临证从三阳论治,针对郁热、火热、湿热、毒热病机,太阳痤疮用麻黄连翘赤小豆汤、翘荷汤、泻心汤、黄连解毒汤化裁;阳明痤疮用茵陈蒿汤、葛根芩连汤、桃核承气汤或茵陈蒿汤合桃核承气汤、三物白散或小陷胸汤、清胃散合升麻鳖甲汤化裁;少阳痤疮用柴胡陷胸汤、柴胡桂枝汤、桂枝茯苓丸合三物白散化裁。     

全胸腔镜与开胸三尖瓣手术后患者炎症反应及心肌损伤情况的比较

目的 全胸腔镜三尖瓣手术是一种微创治疗方式,本次研究重点比较患者接受全胸腔镜及开胸三尖瓣手术后炎症反应和心肌损伤标记物的变化趋势。 方法 回顾性分析2018年1月至2019年4月前来我院手术的88例三尖瓣疾病患者[男53例,年龄（49 ± 19）岁,左室射血分数（63 ± 6）%],其中56例患者接受全胸腔镜手术（三尖瓣成形术50例）,32例患者接受传统开胸手术,全部患者均接受单纯单瓣膜手术。我们将白细胞和C反应蛋白水平作为全身炎症反应的指标,将乳酸脱氢酶、肌酸激酶、肌酸激酶同工酶、天冬氨酸转氨酶和肌钙蛋白水平等作为心肌损伤的标志物。 结果 两组患者入院时各项指标无统计学差异,全身炎症反应于术后第2日达到高峰期,随后逐渐减少。腔镜组患者的炎症指标及心肌损伤标志物水平显著低于开胸组。 结论 与传统开胸三尖瓣手术相比,全胸腔镜三尖瓣手术能明显减少术后心肌损伤和全身炎症反应。     

反义miR-30a-5p抑制脑胶质瘤生长的体内实验研究

ObjectiveTo study the inhibitory effect of knocking down miR-30a-5p on the U87 human glioma xenograft growth and its possible mechanism. MethodsNude mice bearing subcutaneous U87 human glioblastoma were established and treated with miR-30a-5p antisense oligonucleotides (AS-miR-30a-5p) subcutaneous injection. Tumor size was measured every other day until the observation period ended. Researchers executed the animals after the treatment, stripped tumor tissues and extracted RNA and protein. Real-time PCR were conducted to detect the expression of miR-30a-5p. The histopathological characteristics and proliferation and apoptosis biological characters (including SEPT7, PCNA, cyclinD1, MMP-2, apoptosis related factor P53, bcl-2 and caspase3)were evaluated by HE and immunohistochemical staining, Western blot analysis respectively, and the cell apoptosis was detected by TUNEL method.ResultsIn AS-miR-30a-5p treated group, the tumor growth was delayed and the final tumor volume was smaller than that in the control and scr-ODN treated group (F=7.167, P＜0.05), and the expression of miR-30a-5p was knocked down. The expression of PCNA、cyclinD1 were significantly down-regulated while P53、SEPT7 and caspase3 up-regulated. Apoptotic index was increased significantly. ConclusionAs-miR-30a-5p suppresses the growth of U87 human gliomas xenografts significantly. Malignant phenotype of tumors are reversed to a considerable degree. Therefore, miR-30a-5p can be a candidate for targeted therapy of human glioma.     

益气化痰方降脂及抗凝作用的实验研究

益气化痰方以治疗“中风不语，痰蒙清窍”的古代名方“涤痰汤”为基础化裁而成。研究以实验性高脂血症家兔为对象，观察了益气化痰方的降脂作用及其对凝血功能的影响，结果表明，益气化痰方能明显降低高脂血症家兔的血浆胆固醇（ＴＨ）、甘油三酯（ＴＧ），并使高密度脂蛋白——胆固醇含量增高（ＨＤＬ－ＣＨ）；延长血浆凝血酶原时间（ＰＴ）、凝血酶时间（ＴＴ）、白陶土部分凝血活酶时间（ＫＰＴＴ），显示出对凝血过程的抑制。由此提示，益气化痰方既能降低血脂，又可抗凝，认为这是其治疗心脑血管疾病，祛除痰浊，消除瘀滞，畅通血脉的作用机制之一。     

反义miR-21抑制异种移植U251人脑胶质瘤生长的体内研究

目的 探讨敲低miR-21表达抑制裸鼠荷皮下U251人腩胶质瘤生长的疗效和机制. 方法 原位注射miR-21反义寡聚核苷酸(AS.miR-21)治疗裸鼠皮下荷U251人脑胶质瘤.定时测量肿瘤大小评估原位注射AS-miR-21治疗效果:使用Real time PCR和原位杂交方法鉴定治疗后miR-21表达水平下调;采用HE染色和免疫组织化学染色(PCNA、PTEN、MMPs、和Septins)评价治疗后肿瘤牛物学性状改变;TUNEL法检测肿瘤细胞凋亡. 结果 肿瘤生长曲线显示AS-miR-21治疗组肿瘤生长速度及体积小于空白对照与无义序列治疗组(F=52.458,P=0.000);Real-time PCR法:AS-miR-21治疗组miR-21表达下调为对照组的0.018±0.009:原位杂交显示AS-miR-21治疗组miR-21表达水平较对照与无义序列治疗组下调:组织病理学检测表明AS-miR-21治疗后肿瘤恶性度降低;TUNEL法检测可见AS-miR-21治疗组细胞凋亡数显著高于对照与无义序列治疗组(F=141.021,P=0.000).结论 以miR-21作为靶点抑制异种移植U251人脑胶质瘤生长,miR-21可能通过上调抑癌基因PTEN抑制胶质瘤的生长,可以作为人脑胶质瘤基因治疗的侯选靶点.
