Objective:To explore the status and influencing factors of participation in cardiac rehabilitation of cardiovascular nurses.Methods:This is a cross-sectional study. From January to February 2022, a total of 3 047 cardiovascular nurses in members of China Cardiovascular Health Alliance were selected as research objects by convenience sampling method. General data questionnaire and Cardiovascular Nurses Participated in the Cardiac Rehabilitation Questionnaire (CNPCRQ) were used to investigate cardiovascular nurses. Multiple linear regression analysis was used to investigate the influencing factors of participation in cardiac rehabilitation of cardiovascular nurses. A total of 3 047 questionnaires were distributed in this study, and 2 704 valid questionnaires were effectively received, with an effective recovery rate of 88.74%.Results:The total score of CNPCRQ of cardiovascular nurses was (93.23±31.58), which was at a moderate level. Multiple linear regression analysis results showed that age, education, professional title, hospital location, hospital level, position type and hospital type were the influencing factors of participation in cardiac rehabilitation of cardiovascular nurses.Conclusions:The status of participation in cardiac rehabilitation of cardiovascular nurses in China needs to be improved. Role and job content of cardiovascular nurses should be further clarified, and cardiac rehabilitation knowledge and skills training should be strengthened in the future, so as to promote the profession development of cardiac rehabilitation and improve patients' health outcomes.

Objective:To investigate clinical efficacy and safety of dupilumab in the treatment of atopic dermatitis (AD) .Methods:An ambispective study was conducted on 123 AD patients treated with dupilumab in Department of Dermatology, the Second Xiangya Hospital of Central South University from July 2020 to March 2022, clinical data were collected, and efficacy and safety of dupilumab were evaluated. Primary outcomes included scores of eczema area and severity index (EASI) , patient-oriented eczema measure (POEM) , peak pruritus numerical rating scale (NRS) and dermatology life quality index (DLQI) before and after 4-, 8-, 12- and 16-week treatment, and adverse reactions and events were recorded. Comparison of scores before and after treatment was performed using paired t test or repeated measures analysis of variance, Mann-Whitney U test was used for the comparison of efficacy among patients with different types of skin lesions or different IgE levels, and multiple regression model based on robust standard errors was used to analyze factors influencing the efficacy. Results:Among the 123 AD patients, 107 were enolled into the efficacy analysis, and 85 (79.44%) completed at least 4 weeks of treatment, including 6 (7.06%) achieving EASI75 and 23 (27.06%) achieving EASI50, and the EASI, NRS, POEM, DLQI scores (10.41 ± 6.72, 4.12 ± 1.74, 8.60 ± 4.29, 7.81 ± 4.38, respectively) significantly decreased compared with those before treatment (18.08 ± 10.69, 7.21 ± 2.01, 16.88 ± 5.74, 12.95 ± 5.95, respectively; all P < 0.001) in the 85 patients. Among the 107 patients, 47 (43.93%) completed at least 16 weeks of treatment. Among the 47 patients, 23 (82.14%) of 28 adults and 17 (89.47%) of 19 adolescents and children achieved 75% or greater improvement in EASI score; the EASI, NRS, POEM and DLQI scores before the treatment all significantly differred from those 4, 8, 12, 16 weeks after the treatment (all P < 0.001) , and all the scores were significantly lower at weeks 4, 8, 12 and 16 than at the previous adjacent time points (all P < 0.05) . At week 4 during the treatment, the EASI improvement rate was significantly lower in the AD patients with prurigo nodularis than in those without ( U = 151.00, P = 0.006) , while there was no significant difference in the EASI improvement rate between the AD patients with xeroderma and those without ( P > 0.05) ; at week 16 during the treatment, there was no significant difference in the EASI improvement rate between patients with prurigo nodularis or xeroderma and those without (both P > 0.05) . Multiple regression analysis based on robust standard errors at week 16 showed that the improvement degree in the EASI score was not correlated with the type of skin lesions ( β = 3.20, P = 0.075) , but correlated with age ( β = -0.22, P = 0.030) , whether patients were in adulthood ( β = 9.54, P = 0.049) , immediate family history ( β = 7.46, P = 0.017) ; the improvement degree in the NRS score was correlated with the type of skin lesions ( β = 0.55, P = 0.032) , age ( β = -0.04, P = 0.033) , weight ( β = -0.05, P = 0.020) , whether patients were in adulthood ( β = 2.06, P = 0.003) and whether patients received combined treatment with antihistamines ( β = -1.91, P = 0.001) . Adverse reactions: among the 123 patients, 6 (4.88%) developed conjunctivitis, and 2 (1.63%) developed facial erythema. Adverse events: vitiligo-like changes occurred on the right forehead of 1 patient, and 3 patients discontinued the treatment with dupilumab due to Henoch-Sch?nlein purpura, distal axonal damage in peripheral nerves in both upper limbs, and epilepsy, respectively. The causal relationship between these adverse events and dupilumab was unclear. Conclusion:Dupilumab is effective in the treatment of AD with high overall safety, and can serve as a new treatment option for AD patients with an unsatisfactory response to traditional treatment.

Objective: To analyze the status of domestic surgical treatment of synchronous peritoneal carcinomatosis from colorectal cancer in China. Methods: Clinicopathological data of patients who underwent surgery from October 2003 to October 2018 in 16 domestic medical centers was retrospectively analyzed. Excel database was created which covered 77 fields of 7 parts: baseline information of patients, laboratory tests, imaging tests, chemoradiotherapy information, intra-operative findings, postoperative pathology and follow-up data. The Wilcoxon rank-sum test was used for comparison of the measurement data between groups. The χ² test was used for comparison of the categorical data between groups. The survival curve was calculated by the Kaplan-Meier method. Results: Of the 1 003 patients, there were 575 male and 428 female patients with the age of (58.5±14.1) years (range: 18 to 92 years). In a total of 920 patients, the carcinoma of sigmoid colon was performed in 292 cases (31.8%) with the highest ratio. The proportion of patients with liver metastasis and lung metastasis were 27.9% (219/784) and 8.3% (64/769). Preoperative detection of carcino-embryonic antigen level was the most common method in China (87.74%, 880/1 003), and the positive rate was 64.5% (568/880). The correct rate of preoperative imaging tests was 40.7% (280/688). The ratio of peritoneal carcinomatosis index (PCI) scores between 0 and 10 was the highest (59.6%, 170/285). Two hundred and sixty-two (27.0%) patients were performed by totally laparoscopic operation in 971 patients. The resection of primary tumor was performed in 588 of the 817 patients (72.0%). In a total of 457 cases, 253 (55.4%) patients were performed cytoreduction which group scored completeness of cytoreduction (CCR) 0. The postoperative hyperthermic intraperitoneal chemotherapy was implemented in 70 of the 334 cases (21.0%). Among 1 003 cases, 562 cases (56.03%) had complete follow-up data and the median overall survival was 15 months. The primary tumor resection and the CCR scores were affected by the PCI scores. The patients underwent primary tumor resection (187/205 vs. 26/80, χ²=105.085, P=0.000) and the patients were performed cytoreduction which scored CCR 0 or CCR 1 (162/204 vs. 8/78, Z=-10.465, P=0.000) had significant difference between the groups of PCI<20 and ≥20. There was a close correlation between the surgical method and the CCR scores (Z=-3.246,P=0.001).When the maximum degree of tumor reduction was planned, most surgeons would choose laparotomy. The overall survival time was longer in patients with primary tumor resection (P=0.000). The median survival time was 18.6 months in the group of primary tumor resection. Conclusions It is difficult to diagnose the synchronous peritoneal carcinomatosis from colorectal cancer before the operation. Primary tumor resection has an obvious effect to prolong the survival time. It is necessary to standardize the treatment of peritoneal metastasis.

Objective To study the clinical characteristics,cardiac magnetic resonance (CMR)features,and genetype of hypertrophic cardiomyopathy (HCM) in neonates.Method HCM newborns diagnosed at pediatric department of Anzhen Hospital Affiliated to Capital Medical University from January 2015 to December 2018 were retrospectively collected.The clinical manifestations,imaging features and genetype were analyzed.Result During the study period,there were 11 227 deliveries and 11 397 live births.52 of the parturient women were diagnosed as HCM before or during pregnancy (0.46％,52/11 227).54 neonates were delivered from HCM mothers.Among them,5 were diagnosed as HCM (5/11 397,0.04％).In addition,there was another infant patient who was admitted from another hospital.In total,6 HCM infants were included in this study,with 4 males and 2 females.The average gestational age of the infants was (36.6 ± 1.2) weeks,with 3 preterm infants,and the others were full-term infants.The median age of diagnosis was 1 day.The clinical manifestation was that 4 patients needed rest in the course of suckling,3 of them also had accompanied symptoms,with pale face,cyanosis while crying and sweating in each case.CMR showed that the ventricular septum was (6.80 ± 1.78)mm,ejection fraction was (60.0 ± 2.8)％.All six patients showed septal thickening on CMR,including a case with right ventricular myocardial hypertrophy,another with left ventricular outflow tract obstruction and late gadolinium-enhanced.The infants were all treated with metoprolol.They were followed up until 6 months to 2 years old.Among them,4 cases had no progress in myocardial thickening.Two cases had progressive myocardial thickening,one of them was diagnosed as end-stage HCM at 2 year-old.Three MYBPC3 mutations,one MYH7 gene mutation,one MYH7 gene mutation combined with TMPO gene mutation and one RYR2 gene mutation were detected.Conclusion The neonatal HCM is characterized by thickening of ventricular septum,outflow tract obstruction and delayed enhancement of CMR.The most common HCM mutations were MYBPC3 and MYH7,the most common clinical symptoms were breast feeding interruption,followed by cyanosis,pale and sweating.It is suggested that beta-blockers should be recommended for neonates with hypoxic episodes or outflow tract obstruction.

Objective: To conduct the visualization analysis of literatures about problem-based learning (PBL) teaching in nursing based on the Web of Science database, so as to comprehend the development vein, main research power and knowledge foundation in this field. Methods: The relevant literatures retrieved from Web of Science TM Core Collection were statistically analyzed through the website and uploaded into the CiteSpace software to generate knowledge mapping for visualization analysis. Results: A total of 259 relevant literatures were included and the annual publication volume showed a remarkable rising trend. Among those literatures, the work of Professor Barrows had the biggest influence in this field; the United States was the country with the largest publication; the Hong Kong Polytechnic University had the top publication amount; PBL teaching literatures included by Journal of Advanced Nursing, Medical Education and Nurse Education Today were able to reflect the research foundation of this field to some extent. In addition, our study also found four classic literatures, which discussed the scientific rationality of PBL teaching in nursing education from different angles and had significance for laying foundations. Conclusion PBL teaching receives more and more attention in nursing education, but high-yielding authors are few, the distribution of national and institutional research power is uneven, and the overall research foundation is relatively weak, which still needs to be further explored.
