In order to further deepen the reform of public hospitals, to improve the qualified personnel training in Qingpu, and to enhance the overall level of medical health development, Qingpu Municipal Commission of Health and Family Planning In October 2011, a new round of disciplinary construction and personnel training project was also started.Moreover, financial support has been provided to the project.By assessing the whole process, not only has the level of discipline personnel training and medical technology shown significant improvement, the tutors who provided the training also express academic interest and have new a vision for talent cultivation.Qingpu Municipal Commission of Health and Family Planning launched a new round of comprehensive program on researcher training and disciplinary construction in 2011, aimed to further deepen the reform of public hospitals,improve the capacity of health research in Qingpu, Shanghai.We have assessed this program and found that this program has significantly improved the quality of training, and medical technology level in those hospitals;in addition, trainees has shown the increase in the interesting in conducting research and raised vision and prospects.

Objective:To investigate the mutations of the epidermal growth factor receptor (EGFR) gene and its clinical signifi-cance in non-small cell lung cancer (NSCLC). Methods:The EGFR gene mutations of exons 18 to 21 in NSCLC were detected by us-ing the ADx-ARMS? detection kit method. Results:The total mutation percentage in exons 18 to 21 of the EGFR gene was 45.8%(98/214) in NSCLC. These mutations predominantly occur in exons 19 and 21. EGFR gene mutation percentages were found in exons 18 (0.93%, 2/214), 19 (22.0%,47/214), 20 (2.3%, 5/214), and exon 21 (20.6%, 44/214) in the NSCLC. Two NSCLC cases were identified to have double EGFR gene mutations of exons 19 and 21. EGFR gene mutations were more frequently observed with adenocarcinoma histology (50.3%, 93/185) than with squamous cell carcinoma (17.2%, 5/29) (P=0.001). EGFR gene mutations occur more frequently in NSCLC cases in women than in men (P=0.002). EGFR gene mutations were significantly higher in NSCLC with lymphatic metastasis (66.7%) than in NSCLC without lymphatic metastasis (39.5%) (P<0.05). However, no evident association was found between EGFR gene mutations and age, as well as tumor grade and clinical stage of NSCLC (P>0.05). Conclusion:NSCLC, especially lung adenocar-cinomas, has exhibits frequent EGFR gene mutations in China. EGFR gene mutations in exons 19 and 21, combined with the clinical pathological features of lung cancer, can serve as the molecular marker to evaluate the efficacy of EGFR TKI for NSCLC patients.

OBJECTIVE: To explore the relation between methylation status of RAS association domain family 1A (RASSF1A) in patients with advanced epithelial ovarian cancer and the clinical efficacy of cisplatin based neoadjuvant therapy. METHODS: Forty patients with advanced epithelial ovarian cancer were selected and the methylation status of RASSF1A was evaluated by methylation specific PCR (MSP). The clinical efficacy was compared between patients with different methylation statuses of RASSF1A. RESULTS: The response rate of 15 patients with methylation status in the promoter region was 26.6% and that of 25 patients without methylation status was 48.0%, with significant difference (P<0.05). CONCLUSION The methylation status of RASSF1A can influence the clinical efficacy of neoadjuvant therapy in patients with advanced epithelial ovarian cancer.

Objective To identify novel tumor suppressor genes at chromosome 3p24-26 in human nasopharyngeal carcinoma (NPC).Methods Twenty epithelial-derived expressed sequence tags (EST) were selected from chromosome 3p24-26. RT-PCR and Northern blot were used to detect the expression of the ESTs in NPC cell line, HNE-1, and primary cultures of normal nasopharyngeal epithelial cells. One EST, which was substantially downregulated in the HNE-1 cell line, was detected in 19 NPC biopsy samples, cDNA library screening was used to get its full sequence and the sequence of this novel gene was analyzed.Results A novel gene located at chromosome 3p25.3 was obtained and named NAG-7. It was downregulated in 26.3％ (5/19) of NPC biopsy samples. Its 1677 bp full length cDNA had a potential open reading frame predicting a 94 amino acid protein with a molecular weight of 11023.87 Dalton. Analysis of the NAG-7 gene showed that it was a transmembrane protein containing a protein kinase C phosphorylation site and a myristyl site. It has no significant homology to any reported genes in the database of GenBank. Conclusion NAG-7 is a novel gene downregulated in NPC, suggesting that it may be involved in the development of NPC.

Objective To investigate the effectiveness of team-based learning(TBL)combined with research-based learning(RBL)in enhancing evidence-based nursing practice skills of undergraduate nursing interns.Methods A total of 114 undergraduate nursing students who interned in the operating room of a ⅢA hospital in Guangzhou from July 2021 to April 2022 were selected as study subjects.A randomized cluster sampling method based on a random number table was used to divide the students into a control group and a trial group.The control group received traditional teaching methods,while the trial group was taught using a combination of TBL and RBL.The two groups were compared in terms of evidence-based practice skills,critical thinking abilities,and their evaluations on the teaching methods.Results The differences in evidence-based practice skills and critical thinking abilities before and after the internship were significantly higher in the observation group compared to the control group(t=35.108,35.897;both P<0.05).Additionally,post-internship evaluation scores for the teaching methods in the trial group were significantly higher than those in the control group(t=-17.580,P<0.05).Conclusion TBL combined with RBL effectively enhances the evidence-based nursing practice skills and critical thinking abilities of undergraduate nursing interns.This approach also improves students'evaluations on the teaching methods and fosters the cultivation of excellent clinical evidence-based nursing professionals.
