Research progress on the role of SHP-2 in tumor-associated macrophages / 中国比较医学杂志

Tumor-associated macrophages(TAMs)are the predominant cell group in the tumor microenvironment(TME)and are the most important regulatory cells of immune system suppression and tumor cell proliferation in TIME.Src homology-2 domain-containing protein tyrosine phosphatase 2(SHP-2)is a non-receptor protein tyrosine phosphatase that plays an important role in the transmission of signals from the cell surface to the nucleus.SHP-2 is a key intracellular regulatory factor mediating cell proliferation and differentiation and is involved in a variety of growth factor and cytokine signaling pathways linking the cell surface to the nucleus.Recent studies have shown that SHP-2 is a key enzyme in determining the function of TAMs,but because of its variable function,it plays different or even opposite roles in different solid TMEs.This paper reviews the function of SHP-2 in TAMs and related solid tumors to provide a comprehensive reference for tumor immunity and targeted therapy research.

"The experience and thinking of the standardized training of resident in the mode of""social beings""" / 中华医学教育探索杂志

'Social beings' model of standardized training program for residents in Shanghai is one of the important measures in the health care reform. According to the requirements of the standardized training of residents in thoracic surgery, the article preliminarily explored the standardized training model for residents from four aspects such as individualized treatment of different professional backgrounds, focus-ing on the training needs of residents with different starting point of social beings, developing training programs for different training time and combining the master's degree graduate education. And based on the characteristics of thoracic surgery, it also summed up the past experience and explored the clinical practice teaching.

Application of nutrition gastrostomy in the retrosternal route for esophageal reconstruction after operation / 中国肿瘤临床

Objective:Esophageal cancer has high morbidity in China, and surgery is the main treatment for this disease. Postop-erative nutrition is also important for the patients. In this article, we discuss the possibility of retrosternal route gastrostomy feeding (RGF). Methods: The data of 127 esophageal cancer patients between 2011 and 2013 were retrospectively analyzed. RGF was per-formed in all the patients, and post-operation complications were studied. Results: Bowel obstruction, catheter displacement, and wound infection did not occur. Conclusion:RGF is a safe and effective nutrition method for patients who underwent retrosternal recon-struction.

The application of standardized patients in cardiothoracic surgery teaching / 中华医学教育探索杂志

The mode of using standardized patients has been applied in cardiothoracic surgery teaching to assess students efficiency.It alleviates the conflict of the shortage of resource for clinical teaching and improves the quality of teaching and achieves good results.
