熊磊教授基于“脾为痰源”辨治儿童癫痫临证思路探赜

熊磊教授以理脾为本，将治痰贯穿始终。根据小儿脾常不足、肾常虚、肝常有余的生理特点，癫痫发作期治疗主以涤痰开窍，辅以理气健脾，同时配合活血化瘀通窍与平肝息风潜阳。主要选方为柴芍温胆汤、天麻钩藤饮、桃红四物汤加减；缓解期则以补肾养肝为主，兼以健脾化痰，主要选方为杞菊地黄丸合定痫丸加减，取得较好临床疗效。

背景：原发性线粒体病具有高度的临床和遗传异质性，其中周围神经是线粒体病的常见受累器官之一。 目的：总结COX20基因变异相关周围神经病的临床表型及遗传学特征。 设计：病例系列报告。 方法：回顾性收集2018年5月至2020年5月复旦大学附属儿科医院诊治的COX20基因变异相关周围神经病患儿的临床资料，总结其临床表现、基因检测结果及治疗效果，并以“COX20”、“线粒体复合物Ⅳ缺乏症（Complex Ⅳ deficiency）”为关键词检索中英文数据库。检索时间均为从建库至2021年12月。总结已报道COX20基因变异与临床表型的关系。 主要结局指标：临床表型和COX20基因变异位点。 结果：4例患儿纳入分析，男、女各2例，其中3例自幼运动发育落后。4例均在儿童期起病，均以行走不稳为首发症状。肌电图均提示多发性周围神经损害改变，感觉神经轴索受累为主。4例患儿均携带COX20基因复合杂合变异，包括错义变异2个，无义变异和移码变异各1个，其中移码变异c.262delG(p.E88Kfs*35)尚未见报道。文献复习目前共报道COX基因变异18个家系22例患儿（包括本文病例）,起病中位年龄为5（1.0~17）岁，22例均以行走困难或步态不稳起病，11例（50.0%）有精神运动发育迟滞，病程中14例(63.6%)出现构音障碍，14例(63.6%)出现肌力下降和/或足部畸形，8例（36.4%）出现共济失调，6例(27.3%)出现肌张力障碍，5例（22.7%）存在认知倒退等。21例患儿行神经传导及肌电图检查，19例(90.5%)提示多发性周围神经病变。头颅（18例）及脊髓（10例）MR检查提示，脊髓萎缩4例（40%），小脑萎缩4例（22.2%）。9例患儿已无法独立行走，丧失独立行走能力中位年龄为10（7~21）岁。目前共报道9个变异位点，4种变异类型，其中错义变异5个，剪切变异2个，无义变异和移码变异各1个。 结论：COX20基因变异患者多早期起病，以周围神经系统病变为主要表现，可合并构音障碍、共济失调、肌张力障碍、认知倒退等，病情逐渐进展，致残率高。COX20基因变异类型以错义变异最常见。     

Silencing KLF16 inhibits oral squamous cell carcinoma cell proliferation by arresting the cell cycle and inducing apoptosis

Krüppel-like factor 16 (KLF16), a member of the Krüppel-like factor (KLF) family, has been extensively investigated in multiple cancer types. However, the role of KLF16 in oral squamous cell carcinoma (OSCC) remains unknown. Thus, we conducted this study to investigate its related mechanism. KLF16 expression in OSCC cell lines was quantified by western blotting. Then, OECM1 and OC3 cells were divided into Blank, siCtrl, siKLF16#1 and siKLF16#2 groups. Subsequently, cell proliferation was detected using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assays, cell migration and invasion were detected with wound healing and Transwell assays, and cell cycle distribution and cell apoptosis were detected via flow cytometry. KLF16, p21, CDK4, Cyclin D1 and p-Rb expression was detected by western blotting. Finally, xenograft models were established in nude mice to observe the in vivo effects of KLF16 on OSCC. KLF16 protein expression was upregulated in OSCC cells. Compared to the cells in the Blank group, the OECM1 and OC3 cells in the siKLF16#1 group and siKLF16#2 group exhibited a sharp decrease in proliferation but a remarkable increase in apoptosis. Moreover, the proportion of cells in the G0/G1 phase notably increased and that in the S phase decreased, with evident decreases in cell invasion and migration. Moreover, KLF16, cyclin-dependent kinase 4 (CDK4), Cyclin D1 and p-Rb protein expression was upregulated, but p21 expression was downregulated. The mice in the siKLF16#1 and siKLF16#2 xenograft model groups exhibited slower tumour growth and smaller tumours with evident downregulation of Ki67 expression compared to the mice in the Blank group. KLF16 expression was upregulated in OSCC cells, and interfering with KLF16 led to cell cycle arrest, inhibited OSCC cell growth and promoted cell apoptosis.     

中医药治疗耳鼻咽喉头颈外科领域临床优势病种的探讨

小细胞肺癌CT影像学特征及其组织病理特征相关性分析

小细胞肺癌(small cell lung cancer,SCLC)是一种恶性程度高,具有高度侵袭性神经内分泌功能的肿瘤[1-2]。SCLC病情进展快,预后效果较差,研究报道局限期SCLC治愈机率为20%~25%,而广泛期SCLC采用的治疗以放化疗为主[3-4]。由于SCLC发病时具有隐匿特点,早期诊断与鉴别诊断难度较高。但随着临床病理研究的深入,影像学技术水平不断成熟,采用低剂量CT进行肺癌筛查可提高肺癌的早期检出率,并且联合手术、CT引导下穿刺活检、气管镜以及胸水细胞学等辅助检查可进一步增强早期SCLC诊断准确率,临床中尽早了解SCLC CT影像学特征与组织病理特征对于治疗具有临床价值。     

Inhibition of autophagy enhances apoptosis induced by bortezomib in AML cells

Bortezomib is a novel proteasome inhibitor, which has been successfully used to treat mantle cell lymphoma and multiple myeloma. However, the direct effects of bortezomib on acute promyelocytic leukaemia (APL) have not been fully investigated. In the present study, the WST-8 assay, western blotting, flow cytometry, monodansylcadaverine staining and transmission electron microscopy were performed. It was demonstrated that bortezomib treatment induced a time- and dose-dependent decrease in the viability of NB4 cells. Bortezomib treatment induced cell apoptosis in NB4 cells, as assessed by Annexin V/propidium iodide analysis, and the detection of cleaved caspase-3, cleaved poly(ADP-ribose) polymerase, Bax and Bcl-2 expression. Furthermore, bortezomib treatment induced autophagy in NB4 cells, as indicated by autophagosome formation, p62 degradation, LC3-I to LC3-II conversion and formation of acidic autophagic vacuoles. Notably, autophagy induced by bortezomib was initiated prior to apoptosis. Inhibition of autophagy by knocking down Beclin-1 expression increased bortezomib-induced apoptosis in NB4 cells. Therefore, the present study revealed that the combination of bortezomib and autophagy inhibition may be a potential treatment strategy for APL.     

Huayu Pill (化瘀丸) Promotes Fluorescent Doxorubicin Delivery to Tumors in Mouse Model of Lung Cancer

Objective: To study the effect and mechanism of Huayu Wan (化瘀丸, HYW) in combination of chemotherapy of tumor treatment. Methods: HYW serum was added in Lewis cells to assess its impact on fluorescent doxorubicin delivery in vitro. Then, Lewis tumor cells was implanted in C57BL/6 mice via xenograft transplantation. Tumor growth was measured and signal intensity corresponding to blood flow was assessed by laser doppler perfusion imaging (LDPI). Finally, the effect of HYW on the efficacy of doxorubicin was studied. Results: HYW can improve the transfer of fluorescent doxorubicin into cells. The blood flow signal in the tumor tissues of the HYW group was higher than that of the control group (P<0.01). Furthermore, HYW improved drug delivery of doxorubicin to tumor tissues, and this activity was associated with HYW-induced microvascular proliferation (P<0.01). Conclusions: HYW can promote microangiogenesis and increase blood supply in tumor tissues, which in turn may increase the risk of metastasis. At the same time, HYW increases drug delivery and improves the efficacy of chemotherapy drugs through vascular proliferation. Therefore, rational judgment must be exercised when considering applying HYW to an antitumor regimen.

医学生人格特质与共情能力的相关性研究

目的  测评医学生的共情能力现状，探讨人格特质对其共情能力的影响,为培养医学生的共情能力提供对策。方法  以上海市3所高校临床医学专业学生为研究对象，采用班级整群抽样的方式进行问卷调研。采用杰斐逊共情量表-医学生版（JSPE-S）和大五人格量表（NEO-FFI）分别评估医学生的共情和人格特质。结果  共发放问卷2 020份，回收有效问卷1 958份，有效率为96.93%。医学生的共情能力总分均值为（103.24±14.35）。共情能力总分与大五人格中的“外向性”“开放性”“宜人性”“严谨性”维度呈显著正相关（r=0.154~0.406, P<0.01），与大五人格中的“神经质”维度呈显著负相关（r=-0.175, P<0.01）。分层回归结果表明：“共情重要性”和“大五人格”量表的5个维度进入回归方程。其中，人格因素占可解释方差变异量的16.2%（P<0.01）。结论  我国医学生的共情能力低于国外医学生，重视人格特质的塑造有助于提高其共情能力。
