According to the different teaching methods, the control group adopted routine online teaching mode and the experimental group adopted online PBL teaching mode. SPSS 21.0 was used to compare scores of the theoretical knowledge, nursing evaluation, nursing plan, clinical operation and total scores of the two groups. Results:There was no significant difference in theoretical knowledge between the two groups ( P>0.05). The nursing evaluation, nursing plan, clinical operation and total scores of the anesthesia nursing students in the experimental group were significantly higher than those in the control group( P<0.05), and the experimental group had a significantly higher degree of teaching satisfaction than the control group ( P<0.05). Conclusion:During the special period of the COVID-19 epidemic, the online PBL teaching has achieved good teaching effect of online practice of anesthesia nursing specialty, which has ensured "classes suspended but learning continues", and improved the comprehensive examination results of the students. This teaching mode has gained good teaching satisfaction, worthy of clinical promotion and further study.

Objective To investigate the pain management ability of obstetric nurses in puerperants undergoing cesarean section, and to provide some reference for improving the professional knowledge and service ability of obstetric nursing staff. Methods From November 2017 to November 2018, 162 staff in charge of nursing puerperants undergoing cesarean section in Obstetrics Department of 3 ClassⅢ Grade A hospitals were selected by convenience sampling method. General Information Questionnaire, Nurses' Knowledge and Attitudes Survey Regarding Pain(NKAS) were used to investigate and study and compare the pain management ability of nurses with different data. A total of 162 questionnaires were sent out and 156 valid questionnaires were recovered with a recovery rate of 96.30%. Results The scores of NKAS scale of 156 nurses were (15.16±5.42). The scores of "general knowledge of pain", "knowledge of analgesics","knowledge of pain assessment" and "knowledge of pain intervention" were (3.47±0.95), (6.89±1.24), (3.07±0.73) and (1.65±0.98), respectively. There was significant difference in NKAS scores between nurses with different ages, nurses' professional level, education and working years, and the difference was statistically significant (P＜0.05). Multiple linear regression analysis showed that nurses' education and working years were the influencing factors of their pain management ability (P＜0.05). Conclusions The pain management ability of obstetric caesarean section nurses in Nanjing Class Ⅲ Grade A Hospital is low. It is suggested to strengthen the training of pain management ability of obstetric caesarean section nurses with short working length and low professional levels in order to provide better nursing service for puerperants.

Objective To analyze and integrate the best evidence of perioperative assessment and management in patients with chronic obstructive pulmonary disease(COPD).Methods Guideline websites,Chinese and English databases,related society websites were searched systematically to search and extract for guidelines,clinical decisions,recommended practice,evidence summaries,sys-tematic reviews and expert consensus on perioperative assessment and intervention in patients with COPD.The retrieval time was from the establishment of the database to January 31,2023.Results A total of 14 literatures were included:5 guidelines,3 expert consensus,3 clinical decisions,and 3 systematic reviews.Twenty-six pieces of evidence were collected from seven aspects,including gener-al principles,risk factors,nursing assessment,pulmonary rehabilitation nursing,airway manage-ment,effectiveness evaluation and shift management.Conclusion This study summarizes the best evidence of perioperative evaluation and intervention in patients with COPD,which can provide evi-dence-based evidence for perioperative management in patients with COPD.

To target the pivotal BCR/ABL oncoprotein in chronic myeloid leukemia (CML) cells, tyrosine kinase inhibitors (TKIs) are utilized as landmark achievements in CML therapy. However, TKI resistance and intolerance remain principal obstacles in the treatment of CML patients. In recent years, drug repositioning provided alternative and promising perspectives apart from the classical cancer therapies, and promoted anthelmintic mebendazole (MBZ) as an effective anti-cancer drug in various cancers. Here, we investigated the role of MBZ in CML treatment including imatinib-resistant CML cells. Our results proved that MBZ inhibited the proliferation and induced apoptosis in CML cells. We found that MBZ effectively suppressed BCR/ABL kinase activity and MEK/ERK signaling pathway by reducing p-BCR/ABL and p-ERK levels with ABL1 targeting ability. Meanwhile, MBZ directly targeted the colchicine-binding site of β-tubulin protein, hampered microtubule polymerization and induced mitosis arrest and mitotic catastrophe. In addition, MBZ increased DNA damage levels and hampered the accumulation of ataxia-telangiectasia mutated and DNA-dependent protein kinase into the nucleus. This work discovered that anthelmintic MBZ exerts remarkable anticancer effects in both imatinib-sensitive and imatinib-resistant CML cells in vitro and revealed mechanisms underlying. From the perspective of drug repositioning and multi‐target therapeutic strategy, this study provides a promising option for CML treatment, especially in TKI-resistant or intolerant individuals.
