基于VAS评价右美托咪定在宫颈癌根治术后镇痛及术后快速康复中的临床效果

目的:研究右美托咪定在宫颈癌根治术后镇痛及术后快速康复中的临床应用效果。方法:将2015年7月至2018年7月在本院行宫颈癌根治术的86例患者随机分为对照组和观察组各43例。对照组术后镇痛采用舒芬太尼和格拉司琼，观察组术后镇痛加用右美托咪定。采用视觉模拟评分法（VAS）评价患者术后1 h、6 h、12 h、24 h、48 h疼痛情况，采用Ramesay评分法评价患者不同时间点镇静状况，记录并比较两组患者不同时间点收缩压、舒张压、心率及呼吸频率变化，比较两组患者不良反应发生情况。结果:观察组患者术后6 h、12 h、24 h、48 h VAS评分均明显低于对照组（P＜0.05），Ramesay评分均明显高于对照组（P＜0.05）；观察组和对照组患者术后不同时间点呼吸频率比较，差异无统计学意义，但术后6 h、12 h、24 h观察组患者收缩压、心率均明显低于对照组（P＜0.05），术后1 h、6 h观察组患者舒张压明显低于对照组（P＜0.05）；观察组患者恶心呕吐、高血压发生率较对照组明显减低。结论:右美托咪定用于宫颈癌根治术后镇痛，可以提高镇痛镇静效果，稳定患者血流动力学，有助于术后快速康复。     

基于TCGA、THPA、GEO数据库挖掘PTTG1在乳腺癌中的表达及预后意义

目的:通过对癌症基因组图谱(The Cancer Genome Atlas，TCGA)、人类蛋白组图谱(The Human Protein Atlas，THPA)和人类肿瘤相关的基因表达汇编(Gene Expression Omnibus，GEO)数据库的数据挖掘，探索垂体肿瘤转化基因1（pituitary tumor-transforming gene 1，PTTG1）在乳腺癌中的表达及预后意义。方法:从TCGA、THPA和GEO数据库提取PTTG1在乳腺癌及正常组织中mRNA和蛋白水平的变化和患者临床病理资料，GEO在线预后分析数据库Kaplan-Meier Plotter(http://kmplot.com)检索PTTG1乳腺癌预后的相关性。结果:在数据库中，PTTG1 mRNA和蛋白水平在乳腺癌队列中表达显著高于正常乳腺组织(P<0.01)；PTTG1 mRNA在不同的分子亚型中表达存在显著差异(P<0.05)；PTTG1 mRNA在ER和PR阳性乳腺癌患者组织中表达显著低于ER和PR阴性乳腺癌患者(P<0.05)；PTTG1 mRNA在进展期乳腺癌患者组织中表达显著高于早期乳腺癌患者(P<0.05)；PTTG1 mRNA随着乳腺癌患者组织学分级程度升高而降低(P<0.05)。PTTG1低表达乳腺癌患者的预后显著好于其高表达患者(P<0.001)；PTTG1高表达的ER和PR阳性、HER-2阴性乳腺癌患者的预后均显著差于其低表达者(P<0.05)。PTTG1高表达乳腺癌样本富集到细胞因子受体相互作用、趋化因子信号通路、细胞周期、自然杀伤细胞介导细胞毒性、Toll样受体信号通路和T细胞受体信号通路等相关基因集。结论:PTTG1 mRNA和蛋白在乳腺癌组织中高表达，PTTG1 mRNA表达与乳腺癌预后相关且在不同分子分型的乳腺癌中具有不同的预后监测意义，可以作为乳腺癌预后判断的标志物。     

Analysis of Interventional Clinical Research Protocols Related to Coronavirus Disease 2019 and Future Expectations

A case of successful treatment of Fordyce spots with a single insulated microneedle radiofrequency device

Fordyce spots are ectopic sebaceous glands which typically present as asymptomatic, multiple whitish, or yellowish 1–3‐mm sized papules on the lips. Several therapeutic approaches have been proposed such as laser, electrical or chemical ablation, and micropunch excision. However, these modalities pose the risk of scarring from inevitable surface damage. In this report, we present a case of Fordyce spots which was successfully treated with intralesional electrocoagulation using a proximally insulated microneedle and monopolar radiofrequency device, resulting in marked cosmetic improvements without surface damage.

Mixed Reality Combined with Three‐Dimensional Printing Technology in Total Hip Arthroplasty: An Updated Review with a Preliminary Case Presentation

Three‐dimensional (3D) printing technology, virtual reality, and augmented reality technology have been used to help surgeons to complete complex total hip arthroplasty, while their respective shortcomings limit their further application. With the development of technology, mixed reality (MR) technology has been applied to improve the success rate of complicated hip arthroplasty because of its unique advantages. We presented a case of a 59‐year‐old man with an intertrochanteric fracture in the left femur, who had received a prior left hip fusion. After admission to our hospital, a left total hip arthroplasty was performed on the patient using a combination of MR technology and 3D printing technology. Before surgery, 3D reconstruction of a certain bony landmark exposed in the surgical area was first performed. Then a veneer part was designed according to the bony landmark and connected to a reference registration landmark outside the body through a connecting rod. After that, the series of parts were made into a holistic reference registration instrument using 3D printing technology, and the patient's data for bone and surrounding tissue, along with digital 3D information of the reference registration instrument, were imported into the head‐mounted display (HMD). During the operation, the disinfected reference registration instrument was installed on the selected bony landmark, and then the automatic real‐time registration was realized by HMD through recognizing the registration landmark on the reference registration instrument, whereby the patient's virtual bone and other anatomical structures were quickly and accurately superimposed on the real body of the patient. To the best of our knowledge, this is the first report to use MR combined with 3D printing technology in total hip arthroplasty.
