This paper clarifies the reformation of traditional teaching methods in nursing ethics which reasonably combines nursing ethics and nursing aesthetics.Through a variety of teaching methods,clarifying the inner connection of nursing ethics and nursing aesthetics,this paper aims to improve nursing students' passion and enthusiasm for learning nursing ethics,and enhance their analyzing ability to solve related issues in nursing ethics.

Objective: Observing the effect of injecting 5- Fu into the mass of breast hyper-plasia. Methods: We randomly divide the 80 mastopathy patients into two groups ,40 patients ac-cepted the 5- Fu local injection (experiment group),and 40 patients taken orally rubixiaopian and ta-moxifen(control group). The clinical effects of the breast pain and breast lump were observed. Re-sults: The total effect of 5- Fu local injection into the lump of the mastopathy patients was 92.5 % , while control group was 75.0% , its difference was significant(P0.05)in the treatment of mastopathy lump. Conclusion: 5- Fu local injection had obvious effects to breast pain and breast lump of mastopathy.

Objective To observe the clinical efficacy and inflammation of tangential excision within 24 hours after burn with massive deep Ⅱdegree burn wounds for elderly patients. Methods From Jan. 2010 to Dec. 2013, a total of 82 elderly patients with massive deepⅡdegree burn wounds were divided into the observation group ( giveing tangential excision within 24 hours after burn) and the control group ( giveing tangential excision within 3~5 d after burn) according the time of tangential excision treatment. The amount of infused fluid, u-rine, levels of serum inflammatory factors, survival rate of skin grafts, wound healing time, hospitalization time and the complications were compared between the two groups. Results There was no significant difference in the amount of infused fluid, plasma and urine between the two groups in the first day and fifth day (P>0. 05). The levels of TNF-αsignificantly decreased after 3 days of therapy compared with the control group (P<0. 05). The levels of IL-6 significantly decreased and IL-10 significantly increased from the first day of therapy in the ob-servation group compared with the control group (P<0. 05). The survival rate of skin grafts in the observation group was significantly higher than that in the control group, and time of wound healing and hospitalization in the observation group was significantly shorter than that in the control group (P<0. 05). The complication rate of the observation group was 11. 1% which was significantly lower than that in the control group 29. 7% (P<0. 05). Conclusion To treat burn with massive deepⅡdegree burn wounds for elderly patients with tangential excision within 24 hours which can effectively reduce the inflammatory, reduce wound infection and improve the success rate of skin grafting.

Objective To investigate the effect of dexmedetomidine on the incidence of POCD and the inflammatory response of central nervous system in elderly patients with radical gastrectomy,so as to provide reference for the selection of POCD prophylaxis in elderly patients.Methods A total of 86 elderly patients aged 36-79 years with ASA grade Ⅰ-Ⅲ underwent radical gastrectomy with general anesthesia were enrolled.They were randomly divided into two groups using computer random software:dexmedetomidine group (D group) and saline group (S group),43 patients in each group.MMSE score and MoCA score were recorded 1 day before anesthesia (T0),6h after operation (T1),24h after operation (T2) and 48h after operation (T3).Interleukin-1β (IL-1β),interleukin -6 (IL-6) and C-reactive protein (CRP) were measured at different time points.The incidence of hypotension and bradycardia was recorded.Results There were no significant differences in MMSE scores and MoCA scores between the two groups 1 day before anesthesia (t =0.356,0.403,all P ＞0.05).The MMSE score and MoCA score of the D group were significantly higher than those of the S group at T1,T2 and T3 (t =5.998,6.886,5.943,6.180,6.947,7.151,all P ＜0.05).The levels of IL-1β,IL-6 and CRP in the D group were significantly lower than those in the S group at T1,T2 and T3 (t =2.239,2.731,2.134,15.47,17.28,12.93,4.583,6.444,7.544,all P ＜ 0.05).Conclusion Dexmedetomidine can significantly reduce the risk of POCD in elderly patients with radical gastrectomy,and can inhibit the inflammatory response.It is worth to use in clinic.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
