  • Efficacy of dendritic cells vaccines in colorectal cancer: a systematic review

    ObjectivesThe aim of this meta-analysis was to evaluate the adjuvant efficacy of dendritic cell (DC) vaccines against advanced colorectal cancer.MethodsCNKI, CBM, WanFang Data, VIP, PubMed, Web of Science, The Cochrane Library and EMbase were searched to identify studies on dendritic cell vaccine for CRC up to August 13rd, 2017. After independently screening the literature and extracting data, two researchers evaluated the risk of bias in the studies, and used RevMan 5.3.5 software for meta-analysis.ResultsA total of 10 studies involving 2 050 patients were included. Meta-analysis showed that cellular immunotherapy based on DC vaccine treatment can improve the 2-year and 3-year overall survival rate of patients with advanced colorectal cancer (HR=0.33, 95%CI 0.17 to 0.27; 0.26, 95%CI 0.12 to 0.56, P<0.05), while there was no statistically significant difference in 1-year overall survival rate (HR=0.48, 95%CI 0.19 to 1.20, P=0.12); DC-CIK-based cellular immunotherapy could improve 2-year and 3-year overall survival rates (HR=0.27, 95%CI 0.10 to 0.75; HR=0.15, 95%CI 0.04 to 0.54, P<0.05), the difference of 1-year overall survival rate was not statistically significant (HR=0.39, 95%CI 0.13 to 1.13, P=0.08); DC combined with chemotherapy could improve 2-year and 3-year overall survival (HR=0.24, 95%CI 0.10 to 0.56; HR=0.22, 95%CI 0.04 to 0.54, P<0.05); the difference of 1-year overall survival rate was not statistically significant (HR=0.34, 95%CI 0.06 to 2.03, P=0.24); median overall survival in the DC vaccine group (MSR=1.25, 95%CI 1.16 to 1.34, P<0.05) and median progression-free survival (MSR=1.39, 95%CI 1.25 to 1.53, P<0.05) were superior to the control group. Fever was the most common adverse reaction and most patients could be relieved after treatment.ConclusionsDendritic cells vaccines-based immunotherapy can effectively improve the later overall survival rate and prolong median OS of patients with advanced colorectal cancer with mild adverse reactions, however the improvement of short term survival rate is not obvious.

  • Research progress of BCL-2 family apoptotic regulation and its mediated drug resistance after antitumor drug therapy

    Apoptosis is an important means to regulate cell proliferation and maintain homeostasis. Recent researches have shown that the B-cell lymphoma-2 (BCL-2) family not only plays a dominant role in the regulation of normal cell apoptosis, but also plays a crucial role in the formation of tumor genesis, progression and subsequent drug resistance mediated by the escape mode of apoptosis. The phenomenon that BCL-2 family antagonized the apoptosis induced by antitumor drugs and then acquired drug resistance has been reported in the clinical treatment of hematologic lymphatic system tumors, breast cancer, lung cancer, gastric cancer and other diseases. Thus, specific inhibitors targeting anti-apoptotic members of the BCL-2 family have emerged with the development of research. In this paper, we systematically reviewed the regulation of apoptosis mediated by BCL-2 family and the drug resistance mediated by BCL-2 family. Meanwhile, we summarized the research advances of BCL-2 family specific inhibitors to provide new strategy for solving the problems on tumor therapeutic resistance and for finding new therapeutic targets in the future.

  • Study on Hydrolyzate from Aconitine-type Alkaloids in Monkshoo Decoction of Radix Aconiti

    【摘要】 目的 考察用乌头碱水解物、新乌头碱水解物、次乌头碱水解物的含量作为附片水煎剂及附片质量控制指标的可行性。 方法 采用高效液相色谱分析法,色谱柱为Shimpack CLC-ODS,以甲醇-乙酸铵溶液(0.2 mol/L)(200︰210)为流动相,流速1.0 mL/min,检测波长为241 nm,对乌头碱新,乌头碱、次乌头碱水解物的含量测定进行研究。 结果 3种水解物检测方法测得水解物在进样范围有良好线性关系,重现性好,稳定性好,生药提取时间宜选定为40 min,不同批号的附片中3种水解物含量差别较大。 结论 此方法简便,使用新乌头碱、乌头碱、次乌头碱的水解物作为含附片制剂的质量控制指标是可行的。【Abstract】 Objective To examine the feasibility of regarding the hydrolyzate from aconitine, new aconitine, and hypaconitine to be the decoction of radix aconite and the quality control index.  Methods High performance liquid chromatographic method (HPLC) method was adopted. Shimpack CLC-ODS column with UV detection at 241 nm was used. The mobile phase consisted of (200∶210), and the flow rate was 1.0 mL/min. Results The content of the hydrolysis objects in the water decoction and toxicity were correlated with each other, and the contents of hydrolysis were significantly different among different groups of radix aconiti. Conclusion This method is simple, accurate and effective for content research of hydrolyzate from aconitine-type alkaloids in Monkshoo decoction of Radix Aconiti, and it is feasible to take it as the quality control index.

  • The feasibility of using high-definition thoracoscopy to identify sympathetic ganglia during endoscopic thoracic sympathicotomy for primary palmar hyperhidrosis

    Objective To explore the feasibility of using high-definition thoracoscopy to identify sympathetic ganglia during endoscopic thoracic sympathicotomy for primary palmar hyperhidrosis. MethodsThe clinical data of patients with primary palmar hyperhidrosis who underwent thoracoscopic sympathectomy in Taikang Xianlin Drum Tower Hospital from June to July 2023 were retrospectively analyzed. At the same time, the operation video of patients with previous fluorescent thoracoscopic surgery was retrospectively analyzed.Results Finally 100 patients were collected, including 54 females and 46 males, with an average age of 21.92±6.56 years. Five patients were intravenously administered with indocyanine green before operation. During operation, the rate of ganglion display was 92.5% (740/800), the rate of ganglion variation was 32.0% (237/740), and the improvement rate of hand sweat was 100.0% (100/100). In 5 patients with near-infrared fluorescence imaging, the coincidence rate between the ganglion identified under white light and the ganglion displayed by fluorescence was 100.0% (38/38). The display rate of ganglion under white light was 95.5% (107/112), and the display rate under near infrared fluorescence imaging was 96.4% (108/112), and the coincidence rate was 99.1% (107/108). Conclusion With the wide clinical application of high-definition thoracoscopy, accurate thoracic sympathectomy has the feasibility of clinical application.
