Objective:To analyze the fail mode of neoadjuvant therapy combined with surgery for locally advanced esophageal squamous cell carcinoma (ESCC) after long-term follow-up.Methods:Clinical data of consecutive 238 patients with locally advanced resectable ESCC who underwent neoadjuvant therapy combined with surgery in Zhejiang Cancer Hospital from September 2012 to October 2019 were retrospectively analyzed. The failure mode in the whole cohort was analyzed after long-term follow-up. The overall survival (OS) and disease free survival (DFS) rates were analyzed by Kaplan-Meier method. Survival differences were determined by log-rank test.Results:The pathological complete response (pCR) rate was 42.0% in 238 patients. After a median follow-up of 46.1 months, tumor progression occurred in 96 patients (40.3%), including 25 patients (10.5%) with local recurrence, 61 patients (25.6%) with distant metastases, and 10 patients (4.2%) with simultaneous local recurrence and distant metastases. The median OS and DFS were 64.7 months and 49.9 months. And the 3-, 5-, and 7-year OS and DFS rates were 70.0%, 52.8%, 36.4% and 63.5%, 42.5%, and 30.0%, respectively. The 3-, 5-, and 7-year locoregional recurrence-free survival rates and distant metastasis-free survival rates were 86.0%, 71.4%, 61.2% and 70.6%, 55.9%, 43.0%. Compared with non-pCR patients, the overall progression rate and distant metastasis rate of pCR patients were lower (26.0% vs. 50.7%, 16.0% vs. 32.6%, both P<0.05). And the 3-, 5-, and 7-year OS (83.0% vs. 60.2%, 69.7% vs. 41.7%, 50.4% vs. 27.7%, all P<0.001) and DFS rates (80.4% vs. 51.4%, 63.9% vs. 31.2%, 45.9% vs. 20.3%, all P<0.001) were significantly better in pCR patients. Conclusions:Distant metastasis is the main failure mode of patients with locally advanced ESCC after neoadjuvant therapy. Patients with postoperative pCR can achieve better long-term survival.

Background: Esophageal mucosal injury induced by gastroesophageal reflux is a key link to the development of Barrett's esophagus-associated adenocarcinoma. However, the molecular mechanism is still not elucidated. Aims: To investigate the role of differentially expressed genes (DEGs) after stimulating esophageal cells with acid and bile acid in the development of esophageal adenocarcinoma (EAC). Methods: The DEGs were obtained through bioinformatics methods after stimulating esophageal cells with low pH and deoxycholic acid, and GO, KEGG enrichment analysis were performed. Protein-protein interaction (PPI) network was performed to screen the hub genes, and their relationships with prognosis and tumor stage of EAC patients were analyzed. The role of co-expressed genes of GADD45B in EAC was also analyzed. Results: Thirty-one overlapping DEGs were obtained after stimulating esophageal cells with low pH and deoxycholic acid, which mainly enriched in the cytokine-cytokine receptor interaction, transcription factors activity, and regulation of cell proliferation and apoptotic process. High expression of GADD45B was correlated with the survival prognosis and tumor stage of EAC patients. GADD45B and its co-expressed genes were involved in the production of tumor necrosis factor. Conclusions: The high expression of GADD45B induced by acid and bile acid is correlated with the prognosis and tumor stage of EAC patients, and is a potential diagnosis and treatment target for Barrett's esophagus-associated adenocarcinoma.

Objective To investigate and analyze the reasons for the omission of adjuvant radiotherapy after breast-conserving surgery (BCS) in patients with breast cancer.Methods The clinicopathologial characteristics and socioeconomic data of 55 breast cancer patients undergoing BCS without postoperative adjuvant radiotherapy in our hospital from 2012 to 2016 were retrospectively analyzed.Results Among the 55 patients who did not receive radiotherapy,25 patients were due to low local recurrence risk,12 patients were due to economic or family reasons,12 patients were due to fear of adverse reactions of radiotherapy,and 5 patients were not recommended by primary physicians for radiotherapy.In addition,3 cases with multiple distant metastases and 3 cases with concomitant thyroid cancer didn't received radiotherapy.Conclnsions Low risk local recurrence is the main reason for the omission of adjuvant radiotherapy,followed by the fear of radiation-induced toxicity and poor financial support.Patient education and medical insurance may improve the adjuvant radiotherapy compliance.

The "student-centered" concept highlights the dominant position of students in the teaching process and makes up for the deficiency of traditional teaching mode.Based on the above idea,the teaching team of the author's department tried to improve teaching effect through effective teaching design in biochemistry.Firstly,the teaching goal (the goal of knowledge,ability and emotion) and the important situational factors the learning situation analysis,the characteristics of the course and the class,etc)should be identified.suitable teaching strategies he inspiration strategy,exploration strategy and problem solution strategy,etc.),teaching method (discussion,case study,problem based learning,etc.) and proper assessment (such as the summative assessment with formative evaluation) should be determined to organize classroom teaching.At the end of the class the timely feedback and the teaching reflection should be carried outto extend classroom teaching to extra-curricular class.The results showed that effective teaching designismore likely to stimulate students' learning enthusiasm,promote students' deep learning and achieve better teaching effects.

The purpose of education is to cultivate talents who can master the ability of self-learning lifelong. With the rapid development of multimedia technology, the knowledge carrier represented by micro curriculum plays a very important role in improving students' self-learning ability. In traditional Chinese medicine college, due to the short of time, weak learning foundation, the ability of self-learning is hard to improve in the modern medical courses such as biochemistry. This is not conducive to the cultivation of modern talents of Chinese medicine. In this paper, we chose the biochemistry teaching in TCM college as an example, and discuss how we can make the application of micro courses reasonably in the teaching process. This study was regarded as a starting to improve the students' self-learning ability effectively.

Objective To evaluate the high?risk factors for brain metastases after prophylactic cranial irradiation ( PCI), and to provide a basis for personalized treatment. Methods A retrospective analysis was performed in 188 patients with limited?stage small?cell lung cancer who received PCI in our hospital from 2005 to 2010. The Kaplan?Meier method was used to calculate the cumulative rate of brain metastases. The log?rank test and the Cox model were used for the univariate and multivariate analyses of the potential factors for the cumulative incidence of brain metastases, respectively. Results In the 188 patients, 31 ( 16?5%) had brain metastases. The 1?, 2?, and 3?year cumulative incidence rates of brain metastases were 4%, 15%, and 20%, respectively. The univariate analysis showed that staged Ⅲ disease before treatment, elevated levels of tumor markers, incomplete remission after chemoradiotherapy, and local?regional relapse were risk factors for high incidence of brain metastases ( P= 0?044, 0?037, 0?005, 0?007) . The multivariate analysis revealed that incomplete remission after chemoradiotherapy and local?regional relapse after chemoradiotherapy were risk factors for high incidence of brain metastases after PCI ( P= 0?003, 0?040 ) . Conclusions Patients with incomplete remission or local?regional relapse after chemoradiotherapy have high incidence of brain metastases after PCI. For those patients, a frequent follow?up of the central nervous system plus salvage cranial irradiation might provide an alternative to PCI.

Three weeks’ training, visiting and demonstrating classes in Michigan State University gave us an opportunity to understand the education system, the teaching characteristics and the “students centered”teaching principle of USA. Some reasonable teaching methods were applied in the class which may embody the student-oriented teaching aim and develop the students’ subjective initiative. The teaching effect showed that most students were fond of the teaching strategies and they also did good job in final tests.
