基于外邪理论探讨肿瘤的发病机制

肿瘤防控是当今世界性一大难题，目前我国每年新发肿瘤病例即将突破400万。近年来，我国肿瘤总体发病率和死亡率呈现逐年上升趋势，肿瘤的高死亡率和低治愈率已严重威胁我国居民健康，很大程度影响了患者的生存质量，大大降低患者的生活水平，危害患者的身心健康。中医认为，肿瘤发病的病因复杂，病机变化多端，是内外因相互影响、相互作用的结果。若在外邪作用于人体之初，及时辨证施治，防止伏邪入里发生传变，将大大减少肿瘤疾病的发生和发展。因此，外邪理论与肿瘤的发病机制亟待进一步探究。在中国知网（CNKI），Public Medline（PubMed）数据库中以外感、邪气、中医、肿瘤、发病机制等关键词进行检索，本文共纳入67篇中英文文献为参考，对外邪理论与肿瘤发病机制进行全面探讨。强调了外邪在肿瘤发病中的重要作用，以及中医药在早期防治肿瘤中具有显著的优势。外邪如风邪、寒邪、湿邪、火邪、从口鼻皮表而入的邪气等因素，使得肿瘤的发生更具复杂性。中医药可以在肿瘤发展早期进行有效的防护和干预，可大大提高防病抗肿瘤的目的，减少肿瘤的发生、发展、传变，使临床用药更有效、更精准、更具靶向性，不至使肿瘤的治疗错失良机，为临床治疗肿瘤提供更明确的指导方向。     

中药对癫痫相关信号通路调控作用的研究进展

癫痫是一种常见的神经系统疾病，其反复发作，迁延难愈，对患者的身心造成极大危害。抗癫痫药带来良好的治疗作用的同时也伴发着诸多身心损伤的不良反应。中医药治疗癫痫由来已久，目前除不断丰富传统中医理论治疗癫痫的认知理论外，从分子生物学角度研究中医药治疗癫痫的细胞信号传导机制发展迅速。通过对国内外文献检索发现，癫痫发生与细胞增殖、凋亡、自噬、炎症反应、免疫应答等病理生理过程密切相关；同时中西药的现代医学研究表明，无论是中药单体、单味中药甚至中药复方治疗癫痫的机制的研究均与文中所述信号通路有着直接或间接的关系，其可以通过调控相应信号通路的关键分子表达，达到抑制癫痫发生，控制癫痫发作，保护癫痫脑损伤的作用。该文通过对国内外研究现状进行总结，具体如下：①桔皮素，银杏内酯B等能通过激活磷脂酰肌醇3-激酶/蛋白激酶B（PI3K/Akt）信号通路，抑制凋亡及氧化应激反应。②黄芩苷，蛇床子素等能通过抑制哺乳动物-雷帕霉素靶蛋白（mTOR）信号通路，抑制自噬。③灵芝多糖，黄芪甲苷等能通过抑制丝裂原活化蛋白激酶（MAPK）信号通路，减少细胞凋亡。④红景天苷，白藜芦醇等能通过激活核因子E2相关因子2/抗氧化反应元件/血红素加氧酶1（Nrf2/ARE/HO-1）信号通路，抗氧化应激反应及抑制凋亡。⑤姜黄素，黄芩苷等能通过抑制核转录因子-κB（NF-κB）信号通路，降低炎症反应及减少凋亡。以上总结旨在为中药治疗癫痫的深入研究提供参考依据，也为临床中药治疗癫痫提供新的思路。     

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.

Chinese herbal injections combined with rt-PA intravenous thrombolysis for acute ischemic stroke: A systematic review and meta-analysis protocol

Background:Acute ischemic stroke (AIS) is an important factor leading to adult death and disability globally. For AIS patients who meet certain conditions, recombinant tissue plasminogen activator (rt-PA) intravenous thrombolysis is an important method recommended by national guidelines to achieve vascular recanalization. However, complications such as hemorrhagic transformation and vascular reocclusion after thrombolysis are still unsolved problems in clinical. Several systematic reviews of clinical randomized controlled trials (RCTs) in the past have shown that Chinese herbal injections (CHIs) can improve the neurological function of patients, increase the tolerance of ischemic tissues to hypoxia, and inhibit platelet aggregation. Therefore, this study conducted a meta-analysis of AIS treatment with intravenous thrombolysis alone and compared it with the combined application of CHIs. To evaluate whether CHIs have a synergistic effect on thrombolytic therapy and provide a basis for clinical application.Methods:The following databases will be searched until September 2020: ①English databases: PubMed, Cochrane Library, Embase; ②Chinese databases: CNKI, Wanfang database, Weipu database, SinoMed. RCTs will be included to compare the efficacy of thrombolysis combined with CHIs and thrombolysis alone in the treatment of AIS. Data extraction and risk of bias assessments will be carried out by 2 verifiers independently. The risk of bias will be evaluated through the Cochrane risk of bias tool. Review Manager software 5.3 will be used for statistical analysis.Results:This study will provide comprehensive evidence for the treatment of AIS by CHIs combined with intravenous thrombolysis from multiple aspects.Conclusion:The conclusion of the meta-analysis will provide a basis for judging whether CHIs combined with intravenous thrombolysis is an effective measure for the treatment of AIS.Ethics and dissemination:Ethical approval is not needed because this study will be based on data that already published. We will publish the findings of this study in a peer-reviewed journal and related conferences.PROSPERO registration number:CRD42020215546.     

正念行为护理对肺癌合并肺结核患者的护理效果观察

目的探讨正念行为护理对肺癌合并肺结核患者的护理效果。方法选取2019年1月至2020年1月间陕西省结核病防治院收治的97例肺癌合并肺结核患者,采用随机数表法分为对照组和观察组。对照组49例患者采用亲情护理,观察组48例患者采用正念行为护理。比较两组患者的屈服、回避和面对评分、自我效能感量表(GSES)、抑郁自评量表(SDS)和焦虑自评量表(SAS)评分及生活质量。结果护理后,两组患者的屈服、回避、SDS和SAS评分均较护理前降低,且观察组均低于对照组,差异均有统计学意义(均P<0.05)。护理后,两组患者的面对、GSES、情绪功能、社会功能、认知功能、躯体功能和角色功能评分均较护理前升高,且观察组均高于对照组,差异均有统计学意义(均P<0.05)。结论正念行为护理能促进肺癌合并肺结核患者养成积极的应对方式,提高自我效能,减轻不良情绪,提高生活质量,值得推广。     

扶正法治疗精神疾病的心悟

慎察精神疾病患者之症象,准确辨证,若系正气虚匮或不足,予相应之扶正方药、针灸等主治或辅治之,收效颇佳。反之,审证不清,“实而误补,固必增邪”(《顾氏医镜》)。同时,宜鼓励患者多做活动锻炼,增强体质,提高正气,亦可谓一种较好的扶正辅助疗法。

Patterns of patient reluctance to receive complementary-medicine treatments in a hospital setting: A cross-sectional study

ObjectiveWe aim to characterize the patient population that exhibits reluctance to undergo complementary medicine (CM) treatments in a hospital setting.MethodsWe conducted a cross-sectional prospective study among patients prior to hospitalization using structured questionnaires in a single center in Israel. Participants were asked to rate their degree of consent to receiving CM treatments during hospitalization.ResultsThe CM-reluctant group was 7.1 % of the study cohort. The CM modalities most commonly refused were spiritual guidance, acupuncture, and energy and healing therapies. The CM-reluctant population showed a weaker relation to spiritual content and tended to value complementary medicine's effectiveness less in comparison to the CM-consenting group. The main reason for reluctance was skepticism of the perceived effectiveness of CM.ConclusionsWith skepticism playing a major role in decision making, we should question whether the Stakeholders in the field of CM and public health services are succeeding in explaining the benefits and risks of CM treatments.     

基于方剂构成信息的知识发现和关联网络构建挖掘海洋中药海马历代用药经验＊

目的 通过对含海马方剂构成信息进行数据挖掘和知识发现，构建关联网络，分析海马的历代应用情况，挖掘海马用药配伍经验，发现海马潜在功效和主治病症，为海马的临床应用和开发提供依据。方法 以《中医方剂大辞典》《中国药典》《中华医典》等多部著作为方源，收集含有海马的相关方剂，并进行频数分析、关联规则挖掘和关联网络的构建。结果 共筛选有文献记载的含海马方剂154首。从剂型看，大多为散剂，从方剂分布年代来看，海马的应用虽然有很长历史，但是古代应用并不广泛，现代应用较多。通过对配伍药物进行分析发现，与海马配伍频率较高的是“鹿茸”、“熟地黄”、“肉苁蓉”等补益药物。从功效主治方面看，大多数方剂具有“补肾”、“温阳”、“益精”等传统功效外，还具有健脑等功效；主治病症中，除“阳痿”、“癥瘕”、“疔疮”等《中国药典》所记载的疾病之外，还可治疗“虚劳”、“健忘”、“瘿病”、“不寐”、“痹证”、“小便淋沥或不通”等。对其进行关联关系分析发现，海马配伍补肾温阳的效果较为明显，多用于治疗阳痿，且腰痛、虚劳、遗精、健忘、不育等疾病的治疗与补肾关系密切；在治疗癥瘕时，多与醋、樗鸡、干漆、硇砂、斑蝥、水蛭、没药、当归配伍。结论 该研究不仅发现了含海马方剂的常用剂型、分布年代和药物配伍规律，发现了历代医家应用海马的临床经验，还探索了海马的潜在应用价值。海马作为一味海洋中药，具有温、补、托、消等特性，除常用于治疗阳痿外，还可用于治疗腰痛、健忘、瘿病、不寐、痹证等病症，这些研究结果可为拓展海马的临床应用提供理论基础及依据。
