  • 芬氟拉明治疗难治性癫痫的研究进展

    癫痫是神经科常见病,60%在儿童期起病,最终有20%~30%发展为药物难治性癫痫。难治性癫痫是指在使用正确选择且能耐受的两种抗癫痫发作药物的情况下仍不能终止其发作的癫痫,儿童以Lennox-Gastaut综合征(Lennox-Gastaut syndrome,LGS)、Dravet综合征(Dravet syndrome,DS)等为代表,成人以颞叶癫痫为代表。难治性癫痫具有“低治愈率、高致残率、高致死率”的特点,给患者及家属造成巨大的生理和心理上的痛苦。目前,离子类抗癫痫发作药物已难在机制上实现重大突破,而非离子类抗癫痫发作药物的研究则具有广阔的前景,其机制可能涉及癫痫发生的根本机制,而近年来获批上市的芬氟拉明(Fenfluramine,FFA)就属于此类抗癫痫发作药物。多个Ⅲ期随机对照试验研究提示FFA对DS、LGS具有卓越的有效性,为难治性癫痫患者及家属带来了新希望。本文从FFA治疗难治性癫痫的作用机制、药动学、临床疗效、安全性及耐受性等方面进行综述。

  • MicroRNA as diagnostic markers of epilepsy: systematic review and meta-analysis

    ObjectiveThe aim of this meta-analysis and systematic review is to assess the effectiveness of microRNAs as a diagnostic tool for individuals with epilepsy. MethodsA systematic search of PubMed, EMBASE, the Cochrane Library, and Web of Science databases was performed to collect literature on miRNA diagnosis of epilepsy up to January 1, 2024. Two researchers independently screened and extracted the literature and resolved discrepancies by negotiation. The QUADAS-2 evaluation tool was used to assess the quality of the included studies. Statistical analysis was performed using Review Manager 5.4, Meta-Disc 1.4, and Stata 17.0. Results A total of 17 papers were included, including 942 patients with epilepsy and 932 healthy controls. miRNA in the diagnosis of epilepsy had a combined sensitivity of 0.76 [95%CI (0.71, 0.79)], combined specificity of 0.78 [95%CI (0.74, 0.82)], and area under the SROC curve of 0.84 [95%CI (0.80, 0.87)]. Subgroup analysis showed that miRNA had higher diagnostic value for temporal lobe epilepsy, especially medial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS). ConclusionThe study suggests that miRNA may be a promising tool for the diagnosis of epilepsy, especially temporal lobe epilepsy, but more high-quality studies are needed to support it.

  • Correlation between adverse reactions and curative effect in neoadjuvant chemotherapy for breast cancer

    ObjectiveTo analyze the relationship between adverse reactions and curative effect in neoadjuvant chemotherapy, this study is to explore whether the adverse reactions of chemotherapy can indirectly predict the efficacy of chemotherapy, so as to give a new definition of adverse reactions of chemotherapy.MethodsThe clinical data of 64 patients with neoadjuvant chemotherapy for breast cancer (after 4 cycles of TAC regimen) were retrospectively analyzed. The adverse reactions (weakness, nausea, vomiting, alopecia, myelosuppression, cardiotoxicity) during chemotherapy were counted. At the same time, the evaluation of chemotherapy efficacy was carried out according to the RECIST1.1 standard, and the relationship between the degree of adverse reactions of chemotherapy and the curative effect was analyzed one by one. Then, according to the severity of adverse reactions, adopting the form of scoring to assign the value, and use Pearson correlation analysis to clarify the specific relationship between adverse reactions and curative effect. Finally, four subgroups of Luminal A, Luminal B, Her2+ and Sanyin were determined according to molecular typing, and the relationship between adverse reactions and therapeutic effects among different subgroups was analyzed.ResultsThere was no difference in the adverse reactions of chemotherapy in neoadjuvant chemotherapy patients of different ages (correlation coefficient r fluctuated between –0.079 and –0.164, P value fluctuated between 0.195 and 0.533). The patients with high scores of adverse reactions showed relatively good efficacy (r=0.587, P<0.01). There was no significant correlation between fatigue, nausea and vomiting and efficacy (r=0.199, P=0.144; r=0.127, P=0.144). Among the adverse reactions, there was a significant positive correlation between alopecia, myelosuppression, cardiotoxicity and efficacy (r=0.532, r=0.621, r=0.422, all P<0.01). The above correlation was verified in the Luminal A subgroup (r=0.559, P<0.007).ConclusionsThe severity of adverse reactions in neoadjuvant chemotherapy can predict the efficacy of chemotherapy. To a certain extent, the heavier adverse reactions, the better the chemotherapy effect. Hair loss, myelosuppression, and cardiotoxicity have a clearer effect on efficacy in several common adverse reactions.

  • Efficacy of adjuvant radiotherapy for lower thoracic esophageal squamous cell carcinoma patients after radical operation with anastomosis above aortic arch

    Objective To analyze the efficacy of and recurrence mode after adjuvant radiotherapy for lower thoracic esophageal squamous cell carcinoma (TESCC) patients after radical operation with anastomosis above aortic arch. Methods Sixty-three patients with lower TESCC who received adjuvant radiotherapy after R0 radical operation with anastomosis above aortic arch between February 2011 and February 2019 were retrospectively enrolled. The clinical tumor volume (CTV) included anastomotic stoma, and lymph node drainage area in mediastinum and upper abdomen. The survival status, recurrence and metastasis of tumors, and the influencing factors were analyzed. Results The 1-, 2-, and 3-year overall survival rates were 98.3%, 83.3%, and 63.7%, respectively. The median disease-free survival (DFS) was 33 months [95% confidence interval (23.2, 42.8) months], and the 1-, 2-, and 3-year DFS rates were 76.3%, 58.5%, and 41.7%, respectively. Patients with N0-1 had longer DFS than those with N2-3 (median: not reached vs. 15 months, P=0.045). The recurrence rate of anastomotic site was 7.9%. The recurrence rates of lymph nodes in supraclavicular region, upper middle mediastinum, and upper abdomen were 4.8%, 15.9%, and 1.6%, respectively. The distant metastasis rate was 17.5%. The incidence of grade 2-3 radiation pneumonitis, grade 3 anastomotic stenosis, and grade 3 tracheal fistula were 4.8%, 3.2%, and 1.6%, respectively. Conclusions N2-3 is a poor prognostic factor for such patients. Regional lymph node recurrence is mainly revealed in the middle and upper mediastinum. Whether the CTV should include anastomotic stoma and lymph node drainage area in lower mediastinum and upper abdomen is questionable.

  • A governance framework for public health emergencies taking major infectious disease outbreaks as an example: a scoping review

    Objective To summarize and analyze the characteristics, advantages and disadvantages of the current governance framework for public health emergencies in China. Methods The CNKI, VIP, WanFang Data, CBM and PubMed databases were electronically searched to collect studies on the management of major infectious disease outbreaks in China from inception to April 15, 2023. The basic information and governance elements included in the study were extracted and analyzed. Results A total of 30 studies were included, and the time of issuance was from 2020 to 2022. Most of the studies were on COVID-19, focusing on the governance framework of big data governance, holistic governance, and multi-agent collaborative governance. The governance elements were mainly concentrated in three aspects: governance subject, governance cycle and institutional guarantee. The governance entities were concentrated on multi-agent collaborative governance, with the governance cycle mainly focused on in process governance, and the basic guarantee is a multiple guarantee with information technology big data as the main body. Conclusion The governance body of China's major infectious disease epidemic management framework has transitioned from a single entity to a multi entity collaborative governance. While increasing prewarning governance, attention should also be paid to governance during the post recovery period. In terms of system, comprehensive guarantees such as epidemic public opinion control system guarantees, privacy security guarantees, and psychological counseling guarantees should be added.
