The authors give an account of the basic concept and classification of cytotoxic drugs. A center for compounding cytotoxic drugs has been set up in their hospital by using for reference the management experience of the US in this aspect. The center stresses centralized management in compounding cytotoxic drugs, strict operating rules and protective actions, and reduction of possible toxic damages resulting from cytotoxic drugs and infection caused by them in other sectors, thus guaranteeing the physical and mental health of the medical staff. At the same time, the authors call on all medical institutions to pay attention to the disposition of cytotoxic drugs and exert efforts to help a relevant national standard to come out as soon as possible.

The exact scales of volume and density of human internal organs were measured synchronously with the intelligentized volum-densimeter, which was made. by ourself. These primary values of normal and diffuse pathologic changes can refer easily and used for the diagnosis in human autopsy of pathology and forensic pathology. It is expectated to be co-operated widely in that the basic values of volume and density will be obtained from all organs of the human body with the population of different races. But up to now, we are still lack these primary values in anthropology and medicine.

Objective:To evaluate the effectiveness of Orem self-care model for elderly patients with hip fracture.Methods:The databases including Medline, Embase, Web of Science, Cochrane Library Database, Wanfang, CNKI, VIP, and CMB were searched from inception to September 2020. All randomized controlled trials (RCTs) of the Orem self-care model applied in elderly patients with hip fracture were included. Two investigators independently screened research, extracted data and assessed the quality of literature based on standard methods. RevMan 5.3 software was performed to conduct the Meta-analysis.Results:A total of 11 RCTs were included, involving 1 088 patients. Compared with conventional nursing model, self-care model could effectively reduce the incidence of complications during hospitalization ( RR=0.26, 95% CI 0.18-0.39, P<0.001) and improve the Harris scores ( MD=13.33, 95% CI 11.09-15.57, P<0.001) of elderly patients with hip fracture. However, the impacts of self-care model on alleviating postoperative pain was still uncertain. Additionally, the self-care model could shorten hospital stay, but the combined effect size was unavailable due to the high heterogeneity between related studies. Conclusions:In comparison with conventional nursing model, the Orem self-care model was more beneficial to shorten the hospitalization stay, reduce the incidence of postoperative complications and promote hip joint function of elderly patients with hip fractures. To confirm the effectiveness of self-care models in pain management for elderly patients with hip fractures, multicenter RCTs with high quality and large samples are needed.

Objective To investigate the safety and feasibility of robotic nephrectomy,work bench surgery with robotic kidney autotransplantation in the treatment of complex renal tumors.Methods The clinical data of 5 patients with renal tumors admitted from January 2018 to July 2018 were analyzed retrospectively.There were 4 males and 1 females.The median age was 49 years old,ranging 32-66 years.The median body mass index was 25.6 kg/m2,ranging 21.1-27.8 kg/m2.Serum creatinine level was 87.2 μmol/L,ranging 78.0-88.9μmol/L before bench surgery.5 patients had multiple bilateral renal tumors and had undergone laparoscopic or robotic partial nephrectomy on the contralateral kidney.For bench surgery kidney,4 cases were on the left side and 1 case was on the right side.Each kidney has more than 2 separate tumors,combined with complete endophytic tumors,tumors larger than 7 cm in diameter or hilar tumors.5 patients were all performed robotic nephrectomy,work bench partial nephrectomy with robotic kidney autotransplantation under general anesthesia.The patient was first in a lateral decubitus position for robotic nephrectomy,and the kidney was removed through a median 6 cm periumbilical incision.After kidney removal,kidney tumors were resected and kidney was reconstructed on a hypothermic working table.Then the kidney was packed in a plastic bag,filling with ice slush.The corresponding parts of the plastic bag were cut to expose the renal artery and vein.Finally,the patient was moved to lithotomy position with Trendelenburg tilt of 20°,and the autologous kidney wrapped in the plastic bag was placed through the previous periumbilical incision into the abdominal cavity for robotic kidney autotransplantation.The renal artery and vein were anastomosed end-to-side with the right external iliac artery and vein.The ureter and bladder were anastomosed.Autologous kidneys were placed in abdominal cavity in 4 cases,and placed in right iliac fossa with retroperitonealization in 1 case.Ice slush on the surface of the autologous kidney did not completely melt before the blood supply was restored during the operation,and the autologous kidney immediately urinated after the blood supply was restored.Results All surgeries were performed successfully without conversion to open surgeries.The total operation time was 460 min,ranging (415-645 min),the time of robotic nephrectomy was 120 min,ranging (74-300 min),the time of robotic kidney autotransphntation was 135 min,ranging(103-163 min),the warm ischemia time was 3 min,ranging (1.5-6.0 min),the cold ischemia time was 182 min,ranging(135-210 min),the rewarming time was 50 min,ranging(45-55 min),the estimated blood loss during operation was 100 ml,ranging(50-300 ml),and the hospital stay was 6 d,ranging(5-9 d).The number of resected tumors was 4,ranging(2-6).The pathology reveals clear cell carcinoma in 3 cases and chromophobe cell carcinoma in 2 cases.The surgical margins were all negative.The serum creatinine levels were 111.1 μmol/L (87-217.6 μ mol/L) and 106.1 μmol/L (87.1-172 μmol/L) on the 7th and 30th day after operation,respectively.One month after operation,CT showed that the function and morphology of the autologous kidneys were fine.No recurrence or metastasis was found in 5 patients during a median follow-up of 7 months,ranging (5.4-11.7 mon).Conclusions For patients with complex renal tumors who cannot undergo in situ partial nephrectomy,robotic nephrectomy,work bench surgery with robotic kidney autotransplantation can completely remove the tumors,maximize the preservation of renal function and minimize the trauma of patients,making the ultimate means of nephron-sparing surgery for patients with complex renal tumors more minimally invasive and safe.

Objective:To explore the definition and implications of occupational attractiveness among long-term caregivers.Methods:The Walker and Avant concept analysis method was used to define the concept of occupational attractiveness among long-term caregivers.Results:Attributes of occupational attractiveness of long-term caregivers were: (ⅰ) a strength or ability; (ⅱ) mutual attraction between long-term care occupations and incumbents and potential job seekers; (ⅲ) to attract potential job seekers and satisfying their willingness to work; (ⅳ) to retain and motivate in-service long-term care personnel, and enabling them to develop the professional identity and career development.Conclusions:This concept is defined from the perspective of nursing practice in the elderly care service industry in China and combined with the characteristics of long-term caregivers at this stage. It provides clear conceptual support for further relevant research, and provides certain theoretical and practical guidance for the long-term care work of elderly care institutions, communities and families in China.
