目的 探讨康复护理日常生活活动（RNADL）评定在小儿脑性瘫痪（脑瘫）手术后护理的价值。 方法 选择2012年6月－10月200例脑瘫术后患儿为研究对象，随机分为观察组和对照组，每组100例，采用 RNADL对两组患儿进行功能障碍分型判断及障碍等级评定，并分别实施相应治疗方案及护理措施，并就2个月后的康复效果进行评价。 结果 与入组时比较，观察组患儿在2个月时的RNADL评分显著增高（P＜0.01），其2个月时重度障碍的患儿较对照组明显减少（P＜0.05）。 结论 RNADL评定是脑瘫患儿康复治疗的前提和基础，通过正规RNADL评定后采取合理有效的康复治疗方案能明显改善患儿的日常生活能力。
目的 通过检测浸润性乳腺癌中白细胞介素18（IL-18）和血管内皮生长因子（VEGF）的表达情况，探讨其表达相关性及与临床病理学参数的关系。 方法 应用免疫组织化学法检测IL-18和VEGF在42例浸润性乳腺癌组织和12例正常乳腺组织中的表达情况。 结果 IL-18和VEGF在42例浸润性乳腺癌中的表达阳性率均显著高于12例正常乳腺组织（P＜0.05）。且在42例浸润性乳腺癌组织中，IL-18阳性组中VEGF阳性率（87.1%）显著高于IL-18阴性组中VEGF阳性率（12.9%），差异有统计学意义（P＜0.05）。在亚组分析中，IL-18的表达只与有无腋窝淋巴结转移有相关性（P＜0.05），而VEGF的表达与有无腋窝淋巴结转移和TNM分期有相关性（P＜0.05）。 结论 在浸润性乳腺癌中，IL-18的表达上调与VEGF的表达上调显著相关，IL-18可能具有促进肿瘤新生血管形成的作用。
Transcatheter aortic valve replacement (TAVR) is an important treatment for patients with symptomatic severe aortic stenosis. The 2020 updated version of Chinese Expert Consensus on Transcatheter Aortic Valve Replacement was born in the process of Chinese exploration for TAVR. It is of epochal guiding significance for TAVR in China, which has entered a stage of rapid development from the initial stage. Moreover, it further promotes the standardized and healthy development of TAVR in China. The 2020 updated version of Chinese Expert Consensus on Transcatheter Aortic Valve Replacement, based on its 2015 version, has included aortic valve stenosis with a low risk of surgical operation as an indication, made more detailed recommendations on the operating specifications of balloon dilation and valve placement during TAVR, added the antithrombotic program after TAVR, and important opinions on the treatment of coronary atherosclerotic heart disease, renal insufficiency, and emergency TAVR. In this article, we will focus on all these updates to interpret the updated consensus in detail.

The AC impedance of human hepatoma SMMC-7721 cells were measured in our laboratory by Agilent 4294A impedance analyzer in the frequency range of 0.01-100 MHz. And then the effect of hematocrit on electrical impedance characteristics of hepatoma cells was observed by electrical impedance spectroscopy, Bode diagram, Nyquist diagram and Nichols diagram. The results showed that firstly, there is a frequency dependence, i.e., the increment of real part and the imaginary part of complex electrical impedance (ΔZ', ΔZ″), the increment of the amplitude modulus of complex electrical impedance (Δ|Z*|) and phase angle (Δθ) were all changed with the increasing frequency. Secondly, it showed cell volume fraction (CVF) dependence, i.e., the increment of low-frequency limit (ΔZ'0, Δ|Z*|0), peak (ΔZ″p, Δθp), area and radius (Nyquist diagram, Nichols diagram) were all increased along with the electric field frequency. Thirdly, there was the presence of two characteristic frequencies: the first characteristic frequency (fC1) and the second characteristic frequency (fC2), which were originated respectively in the polarization effects of two interfaces that the cell membrane and extracellular fluid, cell membrane and cytoplasm. A conclusion can be drawn that the electrical impedance spectroscopy is able to be used to observe the electrical characteristics of human hepatoma cells, and therefore this method can be used to investigate the electrophysiological mechanisms of liver cancer cells, and provide research tools and observation parameters, and it also has important theoretical value and potential applications for screening anticancer drugs.
ObjectiveTo systematically review the efficacy and safety of dust mite sublingual immunotherapy (SLIT) in the treatment of children with allergic rhinitis. MethodsRandomized controlled trials (RCTs) about SLIT treating allergic rhinitis in pediatric patients was searched in PubMed, EMbase, CBM, Ovid, The Cochrane Library (Issue 5, 2014), CNKI, VIP and WanFang Data from inception to May 2014. Two reviewers independently screened literature according to inclusion and exclusion criteria, extracted data, and assessed methodological quality of included studies. Then meta-analysis was conducted using RevMan 5.3 software. ResultsA total of nine RCTs including 663 patients were finally included. The results of meta-analysis indicated that:the trial group was superior to the control group in reducing the scores of drug use (SMD=-0.61, 95%CI-0.94 to-0.27, P=0.000 4) and mite-specific serum IgE levels (follow-up time > 22 weeks:SMD=0.71, 95%CI 0.31 to 1.12, P=0.000 5). However, no significant difference was found between the two groups in the scores of nasal symptoms (SMD=0.06, 95%CI-0.13 to 0.25, P=0.55) and the incidence of adverse reaction (OR=1.3, 95%CI 0.89 to 1.90, P=0.17). ConclusionSLIT could decrease the use frequency of antihistamine, β-agonist and nasal spray steroids, and it has less adverse reaction and better safety in the treatment of children with allergic rhinitis. But SLIT could neither effectively alleviate nasal symptoms nor reduce mite-specific serum IgE levels of pediatric patients with allergic rhinitis in a short time.
Objective To systematically review and analyze the risk factors of epilepsy in children, to explore the related etiology of epilepsy in children, and to provide evidence-based strategies for reducing the occurrence of epilepsy in children. Methods PubMed, Embase, VIP, CNKI, Web of science, Cohrane, and CBM were searched for relevant studies on risk factors for childhood epilepsy since the establishment of the database, and the study type was selected as a case-control study. After screening and quality evaluation, the literatures that met the requirements were finally selected for inclusion in the study, and the extracted target data were statistically analyzed by RevMan5.3 software. Results A total of 9 literatures were included for Meta-analysis of the risk factors of epilepsy in children. A total of 3792 cases were studied, including 1 922 cases in the control group and 1 870 cases in the case group. Meta-analysis results showed that adverse perinatal period, family history of epilepsy, febrile seizures, and central nervous system infection were closely related to the occurrence of epilepsy in children, and the OR values were OR=3.46, 95%CI (2.51, 4.79), OR=4.77, 95%CI (3.83, 5.95), OR=7.81, 95%CI ( 5.64, 10.80), OR=3.00, 95%CI (1.44, 6.26), P values were all less than 0.05. Conclusions Adverse perinatal period, family history of epilepsy, febrile seizures, and central nervous system infection are the current risk factors for childhood epilepsy.
