The effect of Fufangkushen on gastric cancer cell killing by lines SGC-7901 human γδT cell

Objective To explore the effect of Fufangkushen on gastric cancer cell killing by human γδT cells. Methods Isopentenyl pyrophosphate method was used to amplify human peripheral blood γδT cells in vitro. Fufangkushen at various concentrations was used to induce γδT cells and gastric cancer cell lines SGC-7901 for 24 hours, MTr assays was used to detect inhibitory effect of Fufangkushen on these cell lines, LDH assays was used to measure the cytotoxic activity of γδT cells, and flow cytometry was used to detect apoptosis of γδT cells and SGC-7901 before and after the treatment. Results Ten days after cultivation, proliferation ra-tio of γδT cells increased from 4.21% to 70.35% and CD44 was up to 94.0%. Inhibitory rate of Fufangkush-en on SGC-7901 at various concentrations was significantly higher than that on γδT cells (22.3% vs-22.4%, P<0.05). The negative inhibitory ratio on γδT cells showed a dose-dependent manner with Fufangkushen's concentrations ranging from 1/5 to 1/400. γδT cells cytotoxic activity to SGC-7901 induced by Fufangkushen for 24 h was higher than control group, (83.6% vs 71.2%, P<0.05). Apoptotic rate was significantly lower in γδT cells than in SGC-7901 (4.64% vs49.23%, P<0.05). Conclusion Fufangkushen, within routine concentration ranges, can promote γδT cells' proliferation, inhibit tumor cell growth and enhance γδT cells' cytotoxic activity. This may be beneficial to tumor adoptive immunotherapy and provide evidence for the appli-cation of Fufangkushen in the treatment of tumors.

SII联合hs-CRP预测内镜逆行胰胆管造影术后并发胰腺炎的风险

目的 探讨经内镜逆行胰胆管造影(endoscopic retrograde cholangiopancreatography, ERCP)术后并发胰腺炎(post-ERCP pancreatitis, PEP)与全身免疫炎症指数(systemic immune inflammatory index, SII)及高敏感度C反应蛋白(high-sensitivity C-reactive protein, hs-CRP)水平的关系,进一步分析SII与hs-CRP联合对PEP的预测价值。方法 回顾性分析2021年1月~2022年12月在徐州医科大学第一临床医学院行ERCP治疗患者的临床资料。采用限制性立方样条(restricted cubic spline, RCS)来确定SII和hs-CRP与PEP风险之间的相关性。采用多因素Logistic回归分析影响PEP的因素。采用受试者工作特征(receiver operating characteristic, ROC)曲线评价SII、hs-CRP及其联合对PEP的预测价值。结果 RCS分析结果显示,当SII>669.06×10⁹/L和h-sCRP>13.94mg/dl时,与PEP的发生率呈正相关。PEP的发生率随着炎性状态的增加而升高。SII联合hsCRP的ROC曲线下面积(area under the curve, AUC)为0.819,高于单独SII或hs-CRP。多因素Logistic回归分析结果显示,女性、胆总管较大的结石最大径、术后3h血淀粉酶以及SII和hsCRP水平升高是PEP的高危因素。结论 在一定范围内,炎症标志物SII和hs-CRP水平升高是患者行ERCP术后发生PEP的危险因素。SII和hs-CRP联合使用比单独使用任何一种生物学标志物都更能准确地预测PEP的风险。
