Journal of Chongqing Medical University 1987;0(01):-
Objectives :To investigate the effect of BCG - PSN on the mechanical properties of adhesion between lung cancer cells and human umbilical vein endothelial cells. Methods: Micropipette aspiration technique was used to investigate quantitatively the adhesion force (Fa) and the relative adhesion stress (S1) between high metastatic human lung giant cell carcinoma (PG) cells or low metastatic lung adenocarcinoma (PAa) cells and human umbilical vein endothelial cells (HUVEC). Further,we Invistgated the effect of bacillus of Calmette and Guerin - polysaccharide nucleic acid (BCG - PSN) on Fa and S1. Results: The adhesion force (Fa) of PG cells to HUVEC were higher than that of PAa cells under the experimental condition. With treatment using BCG - PSN, the values of the adhesion force of PAa cells to HUVEC decreased in a concentration - dependent and time - dependent manner. For PG cells, treatment with a concentration of 50?g/ml or higher resulted in a continuous decrease of the cell adhesion force. And the adhesion force to HUVEC decreased continuously with the duration of treament from 30 minutes to 48 hours, but they increased significantly again in 72 hours after treatment. The relative adhesion stress between lung cancer cells and HUVEC,S1,changed almost in the same tendency as the adhesion force,Fa. Conclusion :The adhesion forces of PG cells to HUVEC were higher than that of PAa cells under the experimental condition. The adhesion forces of both of the lung cancer cells to HUVEC can be inhibited by BCG - PSN. These results might be relative to the high metastatic potential of PG cells through blood circulation, and to the antitumor action of HCG-PSN.

5.The role of intraoperatve radiotherapy in the management of breast cancer
China Oncology 2013;(8):590-595
Breast cancer is the most common disease in women worldwide, which not only threatened the women’s survival time, but also inlfuenced their quality of life as well. Within this challenge, it’s important to optimize the current multidisciplinary treatment stratagem for breast cancer. Radiotherapy is one of the most important treatment modality for patients with breast cancer, with the trend to shrink the irradiated volume and shorten the total fraction times in recent years. Intraoperative radiation therapy (IORT) as a fast and convenient procedure has the ability to deliver a high, single-fraction radiation dose to tumor beds with minimal exposure of surrounding tissues (lung, heart, etc.), which could be displaced or shielded right after the tumor removal during the surgical procedure. Right now, IORT has been either integrated as a boost technique in multimodal approaches using postoperative EBRT in the treatment of early breast cancer patients undergoing breast conservation surgery or used as a single dose accelerated partial breast irradiation technique for these patients. This review discussed the rationale of IORT, the beneifts and limitations of IORT, the indication and the clinical results of this procedure, including treatment related side-effects as well in order to provide the preliminary evidence based approach for early breast cancer patients.
6.Surgical treatment of coronary artery lesions caused by Kawasaki disease
Chinese Journal of Applied Clinical Pediatrics 2021;36(10):789-793
Kawasaki disease is an acute self-limiting systemic vasculitis syndrome and usually occurs in children.The small and medium arteries of the whole body are mainly invaded, and marked with coronary arteries.Coronary artery dilation and aneurysm formation mainly occur in the early period.Thrombi, intimal hyperplasia, and calcification could be formed during the later period.Consequently, sometimes, it develops intochronicischemic cardiopathy or myocardial infarction.In that, Kawasaki disease has become the leading cause of acquired heart disease for children in developed countries.Presently, the treatment of coronary artery lesions caused by Kawasaki disease includes drug therapy, and interventional and surgical treatment.However, medications usually fail to solve severe coronary conditions, and only interventional and surgical treatment can we choose.Therefore, the development and indications of interventional and surgical treatment of coronary artery lesions caused by Kawasaki disease were reviewed in this article.
