Résumé
Objective:To compare the efficacies of thoracoscopic segmentectomy and lobectomy in the treatment of elderly non-small cell lung cancer.Methods:260 elderly patients with non-small cell lung cancer(NSCLC)aged>65 years were randomly divided into a control group and a study group, with 130 in each group.The control group received lobectomy via the thoracoscope, while the study group received segmentectomy via the thoracoscope.Data from parameters for surgical performance of the two groups were analyzed and compared.The forced expiratory volume in one second(FEV1)and forced vital capacity(FVC)before and after surgery were compared between the two groups.Results:There was no significant difference between patients in the study group and the control group in the volume of intraoperative bleeding, the number of lymph node resection and the postoperative VAS score(all P>0.05). The operative time of the study group was(136.5±34.9)min, clearly longer than that of the control group(120.8±30.2)min, and the difference between the groups was significant( t=3.876, P<0.001), and the drainage time and total hospital stay for patients in the study group were(4.2±0.5)d and(7.2±1.6)d, respectively, which were much shorter than those for the control group(4.9±0.8)d and(8.7±2.1)d, respectively, and the differences between the groups were significant( t=8.445 and 6.421, P<0.001 for both). For the control group, the preoperative FEV1 and FVC were(99.25±7.15)% and(99.60±7.54)%, respectively, and the postoperative FEV1 and FVC were(65.08±13.06)% and(68.64±13.04)%, respectively; for the study group, the preoperative FEV1 and FVC were(98.42±8.99)% and(100.50±7.35)%, respectively, and the postoperative FEV1 and FVC were(85.09±10.04)% and(86.79±15.88)%, respectively.For both groups, the FEV1 and FVC levels after surgery were significantly lower than those before surgery( P<0.05), but the FEV1 and FVC levels in the study group were significantly higher than those in the control group( t=13.850 and 24.268, P<0.001 for both). There was no significant difference in the incidence of complications between the two groups( P>0.05). Conclusions:Compared with thoracoscopic lobectomy, thoracoscopic segmentectomy is more helpful to reduce postoperative drainage time and hospitalization time for elderly patients with non-small cell lung cancer, and can better protect patients' lung function.

Objective:To study the effect of permissive hypercapnia on pulmonary infection in patients underwent thoracoscopic combined with laparoscopic radical esophagectomy.Methods:From 2018 to 2020, 90 who patients underwent thoracoscopic laparoscopy combined with radical esophagectomy were divided into 3 groups by random who number table method, including 30 patients in experimental group 1, 30 patients in experimental group 2, and 30 patients in control group.PaCO 2 was maintained in the range of 56 mmHg-65 mmHg in experimental group 1, 46 mmHg-55 mmHg in experimental group 2 and 35 mmHg-45 mmHg in control group. The peak airway pressure (Ppeak) , lung dynamic compliance (Cdyn) and oxygenation index (OI) were observed and compared among the three groups after endotracheal intubation (T1) , 30 min after right artificial pneumothorax (T2) and 30 min after right lung recruitment (T3) ;The clinical pulmonary infection score (CPIS) , serum procalcitonin (PCT) on the 1st, 4th and 7th day after operation were analyzed and compared. Results:At T2, observation group A had the highest dynamic lung compliance (25.13 ± 5.70 vs 22.28 ± 4.26 vs 19.99 ± 4.36), the fastest heart rate (102.04 ± 10.91 vs 96.46 ± 9.91 vs 92.28 ± 8.08) and the lowest airway pressure (17.62 ± 1.79 vs 18.96 ± 1.90 vs 20.39 ± 1.71) ( P < 0.05). Observation group A had the lowest CPIS on the 1st, 4th and 7th day after operation compared with observation group B and control group (1.12±0.77 vs 1.71±0.90 vs 2.64±1.07) (6.08±1.20 vs 7.43±1.10 vs 8.31±1.55) (1.69±1.12 vs 2.32±0.98 vs 3.44±1.25) ( P<0.05) . Conclusion:Permissive hypercapnia can reduce airway resistance, improve lung compliance and reduce the risk of postoperative pulmonary infection.

Objective To investigate the effect of bisdemethoxycurcumin on the proliferation and apoptosis of melanoma B16-F10 cells. Methods The B16-F10 cells were incubated with bisdemethoxycurcumin for 24 h, and MTT assay was used to detect the proliferation of B16-F10 cell. Flow cytometry was used to detect cell cycle and cell apoptosis. A C57BL/6 mouse melanoma model was established to investigate the effect of bisdemethoxycurcumin on the proliferation of melanoma. Expression of BCL-1 in B16-F10 cells and tissues was detected by western blotting assay. Results bisdemethoxycurcumin could significantly inhibit B16-F10 cell proliferation, induce B16-F10 cell apoptosis and block the cell cycle at S phase. The intravenous dosing of bisdemethoxycurcumin could inhibit the growth of melanoma. Bisdemethoxycurcumin could inhibit the expression of BCL-1. Conclusion Bisdemethoxycurcumin can inhibit the proliferation of B16-F10 cell, resulting from its role in promoting cell apoptosis.
