[摘 要] 目的：探究炎症标志物对晚期非小细胞肺癌（NSCLC）患者抗PD-1治疗疗效及安全性的预测价值。方法：动态监测2018年1月至2020年12月在海军军医大学第一附属医院接受抗PD-1治疗的222例晚期NSCLC患者的血清炎症标志物，应用ROC曲线计算最佳截断值并将炎症指标分为高和低水平两组。以Log-Rank检验和Kaplan-Meier法分析患者临床病理特征及各炎症标志物水平与患者预后的关系，单因素和多因素Cox回归分析估算PFS和OS的风险比。Fisher精确检验分析各炎症标志物基线水平高和低两组与免疫相关不良反应（irAE）的相关性，Wilcoxon秩和检验比较治疗前（基线）与首次PR、PD时及发生irAE时各炎症标志物水平的差异。结果：血清炎症标志物NLR、MLR、PLR、LDH、CRP和IL-6基线水平升高与患者的PFS和OS显著缩短有关（圴P<0.01）。多因素分析结果显示，基线升高的PLR、MLR和LDH是PFS和OS的独立危险因素（P<0.05或P<0.01）。NLR、LDH、CRP和IL-6水平在患者首次获得PR时显著降低（P<0.05或P<0.01），LDH、CRP、IL-6和TNF-α水平在出现PD时显著升高（P<0.05或P<0.01）。发生irAE时，LDH、CRP、IL-6、IL-10和TNF-α水平与基线水平相比显著升高（P<0.05或P<0.01）。结论：晚期NSCLC抗PD-1治疗中炎症标志物水平的下降提示患者病情改善，其水平的上升则提示病情进展且与irAE的发生相关，动态监测炎症标志物可以预测抗PD-1治疗的疗效及安全性，有助于筛选抗PD-1治疗的最佳晚期NSCLC人群。

Objective: To explore the effect of perioperative chemotherapy on the prognosis of gastric cancer patients under real-world condition. Methods: A retrospective cohort study was carried out. Real world data of gastric cancer patients receiving perioperative chemotherapy and surgery + adjuvant chemotherapy in 33 domestic hospitals from January 1, 2014 to January 31, 2016 were collected. Inclusion criteria: (1) gastric adenocarcinoma was confirmed by histopathology, and clinical stage was cT2-4aN0-3M0 (AJCC 8th edition); (2) D2 radical gastric cancer surgery was performed; (3) at least one cycle of neoadjuvant chemotherapy (NAC) was completed; (4) at least 4 cycles of adjuvant chemotherapy (AC) [SOX (S-1+oxaliplatin) or CapeOX (capecitabine + oxaliplatin)] were completed. Exclusion criteria: (1) complicated with other malignant tumors; (2) radiotherapy received; (3) patients with incomplete data. The enrolled patients who received neoadjuvant chemotherapy and adjuvant chemotherapy were included in the perioperative chemotherapy group, and those who received only postoperative adjuvant chemotherapy were included in the surgery + adjuvant chemotherapy group. Propensity score matching (PSM) method was used to control selection bias. The primary outcome were overall survival (OS) and progression-free survival (PFS) after PSM. OS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the last effective follow-up or death. PFS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the first imaging diagnosis of tumor progression or death. The Kaplan-Meier method was used to estimate the survival rate, and the Cox proportional hazards model was used to evaluate the independent effect of perioperative chemo therapy on OS and PFS. Results: 2 045 cases were included, including 1 293 cases in the surgery+adjuvant chemotherapy group and 752 cases in the perioperative chemotherapy group. After PSM, 492 pairs were included in the analysis. There were no statistically significant differences in gender, age, body mass index, tumor stage before treatment, and tumor location between the two groups (all P>0.05). Compared with the surgery + adjuvant chemotherapy group, patients in the perioperative chemotherapy group had higher proportion of total gastrectomy (χ(2)=40.526, P<0.001), smaller maximum tumor diameter (t=3.969, P<0.001), less number of metastatic lymph nodes (t=1.343, P<0.001), lower ratio of vessel invasion (χ(2)=11.897, P=0.001) and nerve invasion (χ(2)=12.338, P<0.001). In the perioperative chemotherapy group and surgery + adjuvant chemotherapy group, 24 cases (4.9%) and 17 cases (3.4%) developed postoperative complications, respectively, and no significant difference was found between two groups (χ(2)=0.815, P=0.367). The median OS of the perioperative chemotherapy group was longer than that of the surgery + adjuvant chemotherapy group (65 months vs. 45 months, HR: 0.74, 95% CI: 0.62-0.89, P=0.001); the median PFS of the perioperative chemotherapy group was also longer than that of the surgery+adjuvant chemotherapy group (56 months vs. 36 months, HR=0.72, 95% CI:0.61-0.85, P<0.001). The forest plot results of subgroup analysis showed that both men and women could benefit from perioperative chemotherapy (all P<0.05); patients over 45 years of age (P<0.05) and with normal body mass (P<0.01) could benefit significantly; patients with cTNM stage II and III presented a trend of benefit or could benefit significantly (P<0.05); patients with signet ring cell carcinoma benefited little (P>0.05); tumors in the gastric body and gastric antrum benefited more significantly (P<0.05). Conclusion: Perioperative chemotherapy can improve the prognosis of gastric cancer patients.

Objective To study the clinic value of digital three-dimensional shaping titanium mesh in repairing skull defects and reconstructing temporal muscle attachment points. Methods Eighty-two patients with skull defects from December 2013 to January 2016 were enrolled in this study. They were divided into two groups according to patients' will with 41 patients in each group. The patients in control group received traditional hand-shaping titanium mesh repair, the patients in observation group received individual digital forming technology to produce titanium mesh repair and reconstruct the temporal muscle attachment points at the titanium mesh temporal corresponding position. The rate of appearance satisfaction, operation time, the number of titanium nail and the rate of postsurgery adverse reaction was compared between the two groups. Results The rate of appearance satisfaction in observation group was significantly higher than that in control group: 97.56%(40/41) vs. 80.49%(33/41), P<0.05. The operation time and the number of titanium nail and in observation group was significantly lower than that in control group:(8.9 ± 1.6) h vs. (12.4 ± 2.4) h, (10.3 ± 0.9) pieces vs. (11.8 ± 1.8) pieces, P < 0.01. The rate of postsurgery adverse reaction in observation group was significantly lower than that in control group: 0 vs. 9.8%(4/41), χ2 = 4.21, P < 0.05. Conclusions The operation of repairing skull defects and reconstructing temporal muscle attachment points with digital three-dimensional shaping titanium mesh is simple. It can shorten the operation time, decrease the postsurgery adverse reaction, and increase the appearance satisfaction.
