Objective:To investigate the application value of fluorescence imaging in single-port thoracoscopic anatomic segmentectomy.Methods:The clinical data of 280 patients (145 patients with fluorescence method and 135 patients with modified inflation-deflation method) who underwent thoracoscopic anatomic segmentectomy were retrospectively studied in the Anhui Chest Hospital from June 2020 to June 2021. There were 113 patients in the simple segmentectomy group and 167 patients in the complex segmentectomy group. The baseline data of the fluorescence method and the modified inflation-deflation method in the complex segmentectomy group were corrected by propensity score matching, and the perioperative results were compared between the groups.Results:There were no significant differences in segmental resection time, intraoperative blood loss, postoperative drainage, postoperative pain, postoperative extubation time, length of hospital stay, incidence of complications and cost of hand-holding between the fluorescence method and the modified method of the simple segmentectomy group.In the complex segmentectomy group, the time of segmental resection with the fluorescence method was significantly shorter than that with the modified inflation-deflation method( P<0.05), and other indexes had no significant difference. Conclusion:Fluorescence method single-port thoracoscopic anatomic segmentectomy has the same perioperative safety and short-term efficacy as modified inflation-deflation method, which can significantly shorten the operative time and improve the operative efficiency in complex anatomic segmentectomy.

Objective: To explore the effect of Huangqi-Baoxin decoction combined with conventional western medicine on the cardiac function of the patients with diabetic cardiomyopathy (DCM). Methods: A total of 103 DCM patients who met the inclusion criteria were divided into the control group (51 cases) and the research group (52 cases) by random number table method. The control group was treated with conventional therapy, while the study group was treated with Huangqi-Baoxin decoction on the basis of the control group. Both groups were treated for 3 months. TCM syndromes were scored before and after treatment. The serum GSH-Px, SOD and CRP levels were measured by ELISA. Left ventricular ejection fraction (LVEF) and E/A ratio of early diastolic peak velocity to late diastolic peak velocity (E/A) were measured by echocardiography and then evaluate the clinical efficacy. Results: The total effective rate was 92.3% (48/52) in the study group and 76.5% (39/51) in the control group. There was significant difference between the two groups (χ²=4.922, P=0.027). After treatment, the scores of palpitation, shortness of breath, chest tightness and chest pain, fatigue, hypochondriac mass, spontaneous sweating, edema and total scores in the study group were significantly lower than those in the control group (t values were 10.603, 9.997, 10.546, 10.074, 5.211, 3.981, 6.438, 13.502, P<0.01). After treatment, LVEF (46.03% ± 1.70% vs. 42.33% ± 1.63%, t=11.271) and E/A (1.02 ± 0.17 vs. 0.90 ± 0.16, t=3.796) in the study group were significantly higher than those in the control group (P<0.01). After treatment, the serum GSH-Px and SOD levels in the study group were significantly higher than those in the control group (t values were 7.585, 6.816, P<0.01), and CRP level was significantly lower than the control group (t=10.854, P<0.01). Conclusions The Huangqi-Baoxin decoction combined with routine western medicine therapy can improve the clinical symptoms and cardiac function of DCM patients, reduce oxidative stress injury and inhibit inflammation.
