Objective:To explore the application of comprehensive simulated delivery room skill training combined with improved objective teaching in obstetric nursing teaching.Methods:A total of 84 nurses who practiced in the Department of Obstetrics of Nanjing Hospital of Traditional Chinese Medicine from August 2019 to August 2020 were selected as the research objects, and were divided into control group and research group according to the sequence of admission of practice nurses, with 42 nurses in each group. The control group adopted traditional teaching methods, and the research group adopted comprehensive simulated delivery room skill training combined with improved target teaching mode. The teaching effect of the two groups of practice nurses was evaluated by theoretical assessment, skill operation assessment and teaching satisfaction rate. SPSS 22.0 was used for t test and chi-square test. Results:The total score of theory assessment, single choice, multiple choice, blank filling, noun explanation, short answer and case analysis of practical nursing students in the study group were better than those in the control group, with statistically significant differences ( P<0.05). The results of practical skills operation and comprehensive quality ability evaluation of practice nurses in the study group were better than those in the control group, and the difference was statistically significant ( P<0.05). The teaching satisfaction rate of practice nurses in the control group was 80.95%(34/42), and that in the research group was 97.62%(41/42), with statistically significant differences ( χ2=6.10, P=0.014). Conclusion:The skill training of comprehensive simulated delivery room combined with improved objective teaching can improve the theoretical knowledge, practical skills and comprehensive quality of obstetric practice nurses, and improve the teaching satisfaction rate and obstetric nursing teaching quality of practical nurses.

Objective:To observe the clinical characteristics and prognosis of patients with rapidly progressive glomerulonephritis (RPGN) caused by lupus nephritis, antineutrophil cytoplasmic antibodies (ANCA) - associated vasculitis, or primary glomerulonephritis who were treated with peritoneal dialysis (PD) and then withdrew PD because of renal recovery.Methods:Data of the above patients were retrospectively analyzed. The patients were diagnosed as RPGN and received PD therapy in Kidney Disease Center, the First Affiliated Hospital, College of Medicine, Zhejiang University from February 2009 to August 2018. The patients were divided into early withdrawal group (PD time≤183 days, n=24) and late withdrawal group (PD time>183 day, n=24). The differences of clinical characteristics between the two groups were compared. The cumulative incidence of adverse events in both groups was analyzed using Kaplan-Meier curves. Cox proportional hazards model was used to analyze the risk factors influencing the prognosis of patients. Results:Forty-eight RPGN patients were included. The median time of maintaining PD was 178(76, 378) days. Compared with the late withdrawal group, the patients in early withdrawal group had lower levels of urine volume, serum albumin and parathyroid hormone, and lower rates of gross hematuria and hypertension at the beginning of PD, and received higher rates of methylprednisolone impulse, combined immunosuppressive agents, and hemodialysis or continuous renal replacement therapy (all P<0.05). At the time of PD withdrawal, the levels of serum creatinine, serum calcium, serum albumin and parathyroid hormone in the early withdrawal group were significantly lower than those in the late withdrawal group (all P<0.05). The Kaplan-Meier curves showed that there was no significant difference in the cumulative survival of patients in both groups (log-rank test χ2=3.485, P=0.062). Cox regression analysis revealed serum creatinine≥209 μmol/L at the time of PD withdrawal was an independent risk factor for poor prognosis ( HR=5.253, 95% CI 1.757-15.702, P=0.003). Conclusions:PD can be used for RPGN patients caused by lupus nephritis, ANCA-associated vasculitis and primary nephritis. Serum creatinine≥209 μmol/L at the time of PD withdrawal is an independent risk factor for poor prognosis.

Objective: To evaluate the clinical value of high-risk factors in combination with stratification method in predicting the clinical prognosis of patients diagnosed with N_2-3M₀ nasopharyngeal carcinoma (NPC). Methods: A total of 226 N_2-3M₀ NPC patients who underwent IMRT from November 2013 to May 2015 were enrolled in this study. The relationship between tumor volume, cervical metastatic lymph node characteristics (necrosis and fusion) and T and N staging was analyzed. The high-risk factors that affected the survival were identified. The value of high-risk factors combined with stratification method in predicting the clinical prognosis was assessed. Results: N₃ staging, V_n≥47.15cm³ and lymph node fusion (LNF) were the high-risk factors for distant metastasis in patients with stage N_2-3M₀ NPC. All patients were classified into the low-risk, medium-risk, high-risk and extremely high-risk groups according to high-risk factors. For patients in the low-risk, medium-risk, high-risk and extremely high-risk groups, the 3-year overall survival rates were 84.2%, 76.7%, 58.7% and 36.4%(all P<0.001), 87.3%, 85.2%, 54.5% and 12.1% for the distant metastasis-free survival (DMFS) rates (all P<0.001), 76.8%, 74.3%, 49.2% and 12.1%for the progression-free survival (PFS) rates (all P<0.001), and 89.2%, 88.5%, 91.5% and 88.3% for the loco-regional recurrence-free survival (LRRFS) rates (P=0.914), respectively. The risk stratification method showed the best curve separation for DMFS compared to the V_n, N staging and LNF classification groups (all P<0.05). Conclusion High-risk factors in combination with stratification method has the highest clinical value in predicting the clinical prognosis of N_2-3M₀ NPC patients.

Objective? To explore the nursing cooperation of laparoscopic radical distal gastrectomy. Methods? From January 2014 to December 2017, we summarized the main points of nursing cooperation among 41 patients with laparoscopic radical distal gastrectomy at Xi'an Gaoxin Hospital. Results? Among 41 patients, all operations were successful except four of them with laparotomy because of difficult peripheral tissue isolation of stomach or uncontrolled bleeding. The operation time, intraoperative blood loss and postoperative hospital stay were 240 to 350 min, (200±42) ml and (7.0±2.3) d respectively. No patients developed surgical complications during their hospital stay. Conclusions? During operations, nurses are familiar with the surgical procedure, performance as well as methods of application of laparoscopic instruments, and cooperate reasonably and precisely in operation which is the key to carrying out laparoscopic radical distal gastrectomy successfully.

Objective To investigate the effects of serum uric acid (SUA) on all?cause death and cardiovascular death in patients of maintaining peritoneal dialysis (PD). Methods One thousand and sixty?three PD patients in the First Affiliated Hospital of Zhejiang University Medical College were included. The SUA levels at 6 months after PD start were measured. Patients with SUA≥420 μmol/L were grouped in hyperuricemia group (492 cases) and patients with SUA<420 μmol/L were grouped in normal uric acid group (571 cases). The effects on all ? cause mortality and cardiovascular mortality were retrospectively analyzed. Results The median age of the patients was 51(41, 62) years; 557 cases were male (52.40％); the median follow?up time was 33(20, 54) months (6?96 months); 167 cases (15.71％) died during the follow?up period, including 64 cases (6.02％) withcardiovascular causes. The mortality in hyperuricemia group was 19.11％(94/492) and the cardiovascular mortality was 7.93％(39/492), both rates were higher than those in normal uric acid group, and the differences were statistically significant (P=0.005, P=0.015, respectively). Hyperuricemia (SUA≥420μmol/L) at 6 months after PD start (HR=1.572, 95％CI 1.155-2.141, P=0.004), high uric acid level (continuous variable) at 6 months after PD start (HR=1.002, 95％CI 1.001-1.004, P=0.008), and age≥65 years (HR=3.571, 95％CI 2.556-4.990, P<0.001), serum albumin≤30 g/L (HR=1.907, 95％CI 1.278-2.845, P=0.002), high Charlson comorbidity index (HR=1.209, 95％CI 1.032-1.417, P=0.019) at the beginning of PD start were independent risk factors for all ? causes death in PD patients. Hyperuricemia (SUA≥420 μmol/L) at 6 months after PD start (HR=1.734, 95％CI 1.033-2.912, P=0.037) and age≥65 years (HR=1.761, 95％CI 1.024-3.209, P=0.041), with diabetes (HR=2.775, 95％CI 1.358-5.671, P=0.005) at the beginning of PD start were independent risk factors for cardiovascular death in PD patients. Conclusions SUA at 6 months after PD is an independent risk factor for all?cause death and cardiovascular death in PD patients.

Objective To understand the status quo of medical students' integrity in examinations and to explore the influencing factors. Methods 2013-2015 undergraduate students from Clinical Medi-cine, Preventive Medicine and other professional subjects were included in Shanxi Medical University. A total of 221 questionnaires were issued for each grade by stratified random sampling. The database was built with EpiData 3.1. All statical analyses were performed with SPSS software (version 22.0) by means of chi-square test and binary logistic regression. Results Among the 600 medical students, 16.5% of the students had cheating. A statistically significant difference was observed in the cheating rate among the medical stu-dents in terms of gender, grade, academic performance, medical knowledge, memory, family factors, and invigilators' attitude (P<0.05). Litter pressure from the family, the teacher's proctoring is rigorous invigilation, and top scores were the protective factors for medical students' cheating in exams. Conclusion Through the analysis of the influencing factors for the medical students' integrity in examinations, corresponding measures are formulated to provide reference for relevant medical personnel in various medical colleges and universities.
