Objective To observe the effectiveness and safety of Kang′ai injection combined with docetaxel or gemcitabine chemotherapy in treatment of elderly patients with advanced non-small cell lung cancer(NSCLC). Methods A multi-center,randomized and parallel control study was carried out in 150 elderly patients with ad-vanced NSCLC treated in 3 hospitals during the period from June 2013 to August 2014.The patients were randomly divided into platinum-based group(platinum-based doublet chemotherapy)and Kang′ai group(Kang′ai injection combined with single agent chemotherapy). The clinical efficacy,quality of life and adverse reactions were ob-served and compared between the two groups. Results There was no significant difference in the disease control rate between the two groups group(79.66% vs 81.82%)(χ2=0.101,P=0.751)while the effective rate of Kang′ai group was significantly higher than that of platinum-based group(30.51% vs 14.29%)(χ2=5.240,P=0.022). The effective rate of clinical symptom relief in Kang′ai group after treatment was significantly higher than that in platinum-based group(69.49% vs 48.05%)(χ2=6.278,P=0.012),and the increase rate of PS score in Kang′ai group after the treatment was also significantly higher than that in platinum-based group(18.64% vs 3.90%)(χ2=7.868,P=0.005).There was no significant difference in quality of life between two groups(P>0.05).The quali-ty of life score of Kang′ai group was significantly higher than that of platinum-based group at the second course of treatment(P<0.05).The incidence of adverse reactions in Kang′ai group was significantly lower than that in the platinum-based group(47.46% vs 71.42%)(χ2= 8.070,P < 0.05). Conclusion Kang′ai injection combined with single agent chemotherapy can effectively relieve clinical symptoms and reduce the tumor size in elderly patients with advanced NSCLC,with high safety.

This paper focused on the research progress of the assessment methods of carers′ fall concern for the elderly. The content of this review included the definition of carers′ fall concern, and the advantages and disadvantages of various assessment method of carers′ fall concern for the caregivers to the elderly, such as qualitative interviews, questionnaires, and scales. Through this review, the authors hoped to provide a reference for selecting or developing a localized carers′ fall concern assessment tool.

Objective:To construct a core competency evaluation index system for ophthalmic specialist nurses so as to provide theoretical reference for cultivation and evaluation of ophthalmic specialized nurses in China.Methods:A research group was set up in October 2020, and the core competency evaluation index system for ophthalmic specialist nurses was initially formed by means of literature review, semi-structured interview and group discussion. From December 2020 to January 2021, an online questionnaire was used to conduct Delphi letter consultation among 23 experts in related fields nationwide, and the items were screened and modified. The weight of indicators was determined by the proportional distribution method.Results:Two rounds of consultation were conducted. The positive coefficients of experts were respectively 91.30% and 100.00%, Kendall's concordance coefficients were respectively 0.172 and 0. 192 ( P<0.05) , and the expert authority coefficient was 0.90. Finally, an index system consisting of 5 first-level indicators, 12 second-level indicators and 58 third-level indicators was formed. Conclusions:The core competence evaluation index system of ophthalmic specialist nurses constructed in this study has a high degree of enthusiasm and authority of experts, which reflects the characteristics of the ophthalmic nursing specialty and provides theoretical reference for cultivation and ability evaluation of ophthalmic specialist nurses in China.

Objective:To develop a Core Competency Scale for Ophthalmic Specialist Nurses and test its reliability and validity.Methods:This study was a questionnaire development study. This study transformed the core competency evaluation indicators for ophthalmic specialist nurses constructed through literature review, semi-structured interviews, expert consultations, and other methods to form the initial draft of the Core Competency Scale for Ophthalmic Specialist Nurses. From October 2022 to March 2023, a survey was conducted on 364 ophthalmic specialist nurses in China using purposive and snowball sampling. Item analysis, exploratory factor analysis, and reliability testing were performed on the scale.Results:The final Core Competency Scale for Ophthalmic Specialist Nurses included six dimensions of ophthalmic specialized knowledge, ophthalmic specialized skills, essential nursing practice ability, communication and education ability, scientific research ability, and professional competence, totaling 30 items. Exploratory factor analysis extracted six common factors, with a cumulative variance contribution rate of 73.077%. The total Cronbach's α coefficient of the scale was 0.955, the half reliability coefficient was 0.796, and the retest reliability coefficient was 0.973.Conclusions:The Core Competency Scale for Ophthalmic Specialist Nurses has good reliability and validity, which can be used to evaluate the core competency of ophthalmic specialist nurses.
