Résumé
In recent years， the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine， the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances， TCM theories of etiology and pathogenesis， the role and advantages of TCM in the whole course management of pulmonary nodules， contents and methods of research on pulmonary nodules， and science popularization work， aiming to provide a reference for clinical practice and scientific research. After discussion， the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness， blood stasis， and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules， improving physical constitution， ameliorating multi-system nodular diseases， reducing anxiety and avoiding excessive diagnosis and treatment， and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present， the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed， which needs to be further studied from multiple perspectives such as clinical epidemiology， biology， and evidence-based medicine. The primary task of current research is to find out the advantages， effective prescriptions， and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time， basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized， scientific， and accurate effective diagnosis and treatment.

Objective:To investigate the clinical significance of coagulation function related indicators in the prognosis of non-small cell lung cancer.Methods:The clinical data of 248 patients with non-small cell lung cancer from June 2014 to December 2017 in the Department of Oncology, Beijing Hospital of Traditional Chinese Medicine, Capital Medical University, were retrospectively analyzed. The receiver operating characteristic (ROC) curve was used to determine the best cutoff values of prognostic indicators,the Cox regression model was used for multivariate analysis, and the Kaplan-Meier method was used for survival analysis.Results:ROC curve analysis showed that the best cutoff values for D-dimer (D-D), fibrinogen (FIB) and prothrombin time (PT)were 0.18 mg/L, 4.25 g/L and 12.0 s, respectively. Cox multivariate regression analysis showed that increased expression of D-D ( HR=1.197, 95% CI 1.100-1.303), PT ( HR=1.111, 95% CI 1.049-1.176) and FIB ( HR=1.510, 95% CI 1.276-1.788) were risk factors for the prognosis of non-small cell lung cancer ( P<0.001). Kaplan-Meier survival analysis results showed that the overall survival in the high expression group of D-D, FIB and PT was shorter than in of the low expression group ( P<0.001). Conclusion:D-D, PT and FIB are independent factors affecting the prognosis of non-small cell lung cancer.

Objective Subcutaneous transplantation Lewis lung carcinoma model is commonly used in experimental studies.Researchers often choose different transplantation sites to create the models while little attention was paid on the effect of different inoculation sites on the formation of transplanted tumors.The aim of this study was to compare the effect of tumor cell inoculation at different sites on tumor formation in mice.Methods Lewis lung adenocarcinoma (ll2-luc-m38) cells stably expressing luciferase protein were subcutaneously injected into C57 BL/6 mice at the right armpit, right groin, or footpad, respectively.An IVIS spectrum in vivo imaging system was used to observe the tumor and metastasis formation.The survival time and mortality were recorded.H-E stained pathology was performed to examine the histological changes of the lung tissues and tumor metastesis.Results The tumor formation time was earlier in the armpit and groin groups, both with a tumor formation rate of 100%, while the tumors occurred later, with a tumor formation rate of 33% in the footpad group.The pulmonary metastasis rate was 70% in the groin group, 50% in the ampit group, and 0% in the footpad group, at the 21st day after inoculation.The footpad group had a high mortality.The tumors in the groin group and armpit group can be surgically resected, with a postoperative survival rate of 100%.Conclusions In this mouse model of subcutaneously transplanted Lewis adenocarcinoma, the groin and ampit groups have advantages such as a high tumor formation rate, good tolerance of tumor resection, low surgical mortality rate, easy to monitor, simple operation and high reproducibility.The axillary group has an even higher metastasis rate.

Objective To observe the effects of dredging collaterals and activating blood worm Chinese materia medica on angiogenesis related factors of lung cancer in hypoxic environment. Methods The lung cancer A549 cells were cultured in vitro to simulate tumor hypoxia microenvironment by the hypoxia workstation, and different concentrations of Scorpio, Scolopendra and Gecko medicated serum were added. MTT method was used to detect cell proliferation and screen the best medicine concentration and duration of action. Lung cancer A549 cells were administrated by the three kinds of medicated serum, and cells were collected and supernatant was cultured. Contents of VEGF, TGF-β1, and bFGF were detected by ELISA. Results Three kinds of medicated serum had the inhibitory effect on both added normoxia and hypoxia in cultured A549 lung cancer cells. 7.5% concentration of medicated serum was selected, and 24 h later were used in later experiments. Scorpio, Scolopendra and Gecko medicated serum can more reduce the contents of VEGF, TGF-β1 and bFGF in the supernatant of A549 cell compared with the control group (P<0.05, P<0.01). Conclusion Dredging collaterals and activating blood worm Chinese materia medica had inhibitory effect on cancer cells and the regulation of angiogenesis related cytokines in the condition of normoxia and hypoxia.

Objective To investigate the effectiveness of intermittent pneumatic compression (IPC) devices combined with anticoagulants for the prevention of deep vein thrombosis (DVT) after joint replacement surgery.Methods All of 400 patients were involved in this prospective randomized control study with 100 total knee arthroplasty (TKA) patients and 100 total hip arthroplasty (THA) patients in each group.All patients were operated under the general anesthesia.Patients in the control group received 10 mg of rivaroxaban per day beginning 6-8 hours after the surgery.Besides the prescription of rivaroxaban, IPC devices were used just after the anesthesia in the operating theater and lasted for 48 hours in the experimental group.The diagnosis of DVT in the lower extremities was made by color Duplex sonography on the second postoperative day.The incidence rate of DVT and symptomatic pulmonary embolism was recorded.The incidence rates of total DVT, proximal DVT (p-DVT, proximal to the trifurcation of the popliteal vein), distal DVT (d-DVT, in the anterior tibial vein, posterior tibial vein or peroneal vein) and intermuscular DVT were recorded.CT pulmonary angiography was used to confirm the pulmonary embolism if it was suspected.Results The incidence rates of overall, proximal, distal and intermuscular DVT were 9.5％, 0.5％, 0.5％, 8.5％ in the experimental group and 30％, 0.5％, 5.5％, 24％ in the control group respectively.The incidence rates of total DVT, distal DVT and intermuscular DVT were significantly lower in the experimental group.The incidence rate of DVT in TKA patients and THA patients were significantly lower in the experimental group than in the control group respectively.For patients with DVT, enoxaparin was used instead of rivaroxaban, and DVT was found disappeared by color Duplex sonography 10-12 days postoperatively.Conclusion Compared with the use of rivaroxaban alone, IPC devices combined with anticoagulants can significantly reduce the incidence rate of distal DVT and intermuscular DVT in the early postoperative period after joint replacement surgery.
Résumé
Third-generation aromatase inhibitors (AIs) have been considered as standard adjuvant endocrine therapy for hor-mone-responsive breast cancer in postmenopausal women. Aromatase inhibitor-associated musculoskeletal symptoms (AIMSS) are prevalent among patients undergoing AI therapy;these symptoms result in reduced quality of life and poor dependence to AI treatment. The mechanisms mediating AIMSS and the effective management of AIMSS have not been extensively investigated. This article re-views the incidence, clinical characteristics, possible mechanisms, and treatment of AIMSS.
