针刀松解联合丹参注射液关节腔注射治疗骨性关节炎模型兔

文题释义： 针刀疗法：用一个完整的语言来概括应该是一种介于手术方法和非手术疗法之间的闭合性松解术。针刀疗法是将东方中医学的基本理论和西方医学的手术解剖基本理论融为一体，针刀疗法其操作的特点是在治疗部位刺入深部到病变处进行轻松的切割、剥离等不同的刺激，以达到止痛祛病的目的。 丹参注射液：其化学成分主要是水溶性酚酸类化合物，通过多种靶标起到促进血液循环和祛瘀的作用。动物研究表明，丹参注射液可通过抑制IκBα磷酸化来抑制NF-κB信号通路的激活。保护软骨下骨及软骨细胞，有效防治骨关节炎。 背景：丹参注射液与针刀松解术都是临床中治疗骨关节炎很常用的技术，目前缺乏对2种治疗方法联合使用的研究。 目的：对比单独使用针刀松解术、单独使用丹参注射液与两种方法联合使用治疗兔模型骨关节炎的效果。 方法：实验方案经黑龙江中医药大学动物实验伦理委员会批准。50只新西兰白兔分为5组：空白对照组；模型组；丹参注射液组；针刀组；针刀联合丹参注射液组。除空白对照组外，其他4组兔均制备膝关节骨关节炎模型。造模成功后，对针刀组兔内外侧支持带、内外侧膝眼，膝关节上方髌上囊、股四头肌各肌肌腹，膝关节内侧股薄肌肌腹及止点、收肌肌群肌腹及止点和胫骨平台附近部位进行针刀松解；空白对照组及模型组兔关节腔注射生理盐水0.3 mL；丹参注射液组兔关节腔每次注射0.3 mL丹参注射液；针刀联合丹参注射液组：每周进行1次针刀治疗同针刀组，每次针刀干预之后，关节腔注0.3 mL丹参注射液。上述干预每周1次，持续5周。对各组兔膝关节软骨进行大体观察及病理切片组织学观察，ELISA 检测关节液白细胞介素1、肿瘤坏死因子α水平。 结果与结论：①大体观察：模型组膝关节磨损较为严重，针刀组、丹参注射液组、针刀联合丹参注射液组膝关节轻度磨损；②病理切片评分：丹参注射液组评分略高于针刀组和针刀联合丹参注射液组差异无显著性意义；③ELISA 检测结果：针刀联合丹参注射液组白细胞介素1、肿瘤坏死因子α水平显著低于或针刀组或丹参注射液组(P < 0.05)；④结果说明，在兔膝关节骨关节炎模型中降低白细胞介素1、肿瘤坏死因子α水平方面，针刀松解术结合丹参注射液关节腔注射治优于单独使用针刀或单独使用丹参注射液关节腔注射。ORCID: 0000-0003-4119-633X(刘广宇) 中国组织工程研究杂志出版内容重点：组织构建；骨细胞；软骨细胞；细胞培养；成纤维细胞；血管内皮细胞；骨质疏松；组织工程     

经Ⅰ期造瘘口单部位腹腔镜辅助Martin-Duhamel术在全结肠型巨结肠症治疗中的应用

目的探讨经Ⅰ期造瘘口单部位腹腔镜辅助Martin-Duhamel术在先天性全结肠型巨结肠症患儿治疗中的应用价值,并对患儿术后排便功能进行评价。方法回顾性分析2014年6月至2017年6月间河北医科大学第二医院小儿外科收治的15例先天性全结肠型巨结肠症患儿的诊治及术后随访资料,其中男11例,女4例,月龄(5.11±2.67)个月,所有患儿Ⅰ期行回肠末端造瘘术,Ⅱ期行腹腔镜辅助Martin-Duhamel手术。术后随访2年,采用李正肛门功能临床评分法进行排便功能评分。定期肛管直肠测压,记录和比较患儿排便频率、性状及近远期并发症情况。结果15例均顺利完成手术,无中转开腹和死亡病例。手术时间(184.43±30.46)min,出血量(27.57±10.63)mL,肠功能恢复时间(3.29±0.91)d,术后住院时间(7.86±1.77)d。术后1~3个月排便频率为8~20次/日,术后6~9个月排便频率为4~8次/日,术后1~2年排便频率为2~4次/日(接近正常水平)。术后3个月和术后6个月排便评分无显著性差异(P=0.115),术后6个月和术后1年排便评分有显著性差异(P=0.040),术后1年和术后2年排便评分无显著性差异(P=0.542)。肛管直肠测压从术后6个月开始逐渐恢复至正常范围,与术前比较有显著性差异(肛管反射舒张压P=0.027;肛管静息压P=0.010;直肠静息压P=0.034)。术后6个月内因排便次数多致肛周湿疹、皮肤破溃6例,予以造口粉、氧化锌或芦荟软膏涂抹后恢复;小肠结肠炎1例,经保守治疗后缓解;无便秘等其他并发症发生。结论经Ⅰ期造瘘口单部位腹腔镜辅助Martin-Duhamel术治疗全结肠型巨结肠症患儿安全可行;排便功能可在术后6个月至1年逐渐恢复至接近正常儿童的水平。     

Assessment of endometrial receptivity during implantation window in women with unexplained infertility

Abstract

This study aimed to assess the endometrial receptivity during implantation window in women with unexplained infertility. A prospective study recruited 168 women with unexplained infertility and 169 fertile women. Ultrasonic parameters and biomarkers in the uterine fluid were detected. The endometrial vascularization index (VI), flow index (FI) and vascularization flow index (VFI) were significantly higher in fertile women as compared with unexplained infertile women, and the integrin αvβ3, vascular endothelial growth factor (VEGF), tumor necrosis factor alpha (TNF-α), and leukemia inhibitory factor (LIF) levels in uterine fluid were significantly higher in fertile women. The biochemical pregnancy rate, clinical pregnancy rate, and ongoing pregnancy rate in fertile women were 20.12%, 18.34%, and 17.75%, respectively, which were significantly higher compared with unexplained infertile women (7.14%, 5.36%, and 4.17%, respectively). Endometrial thickness (ET), endometrial volume (EV), VI, FI, and VFI measured by ultrasound, and the integrin αvβ3, VEGF, TNF-α, and LIF levels in uterine fluid were all significantly higher in pregnant women as compared with nonpregnant women. The best parameters of ultrasonic indicators for predicting endometrial receptivity in women with unexplained infertility were FI(AUC = 0.894, sensitivity 93.8%, and specificity 83.1%). Integrin αvβ3 had the best predictive value for endometrial receptivity among biomarkers in the uterine fluid (AUC = 0.921, sensitivity 96.7%, and specificity 89.5%). Women with unexplained infertility present declined endometrial receptivity. Endometrial ultrasonic parameters detected by three-dimensional power Doppler and biomarkers in the uterine fluid may be effective indicators to predict endometrial receptivity.

Artificial intelligence-assisted psychosis risk screening in adolescents: Practices and challenges

Artificial intelligence-based technologies are gradually being applied to psych-iatric research and practice. This paper reviews the primary literature concerning artificial intelligence-assisted psychosis risk screening in adolescents. In terms of the practice of psychosis risk screening, the application of two artificial intelligence-assisted screening methods, chatbot and large-scale social media data analysis, is summarized in detail. Regarding the challenges of psychiatric risk screening, ethical issues constitute the first challenge of psychiatric risk screening through artificial intelligence, which must comply with the four biomedical ethical principles of respect for autonomy, nonmaleficence, beneficence and impartiality such that the development of artificial intelligence can meet the moral and ethical requirements of human beings. By reviewing the pertinent literature concerning current artificial intelligence-assisted adolescent psychosis risk screens, we propose that assuming they meet ethical requirements, there are three directions worth considering in the future development of artificial intelligence-assisted psychosis risk screening in adolescents as follows: nonperceptual real-time artificial intelligence-assisted screening, further reducing the cost of artificial intelligence-assisted screening, and improving the ease of use of artificial intelligence-assisted screening techniques and tools.
