Objective:To explore the feasibility, practicality, and safety of the day surgery management model for the treatment of patent ductus arteriosus with Da Vinci robotic surgery in children.Methods:A non-randomized controlled study was conducted.The clinical data of children with patent ductus arteriosus who underwent Da Vinci robotic surgery at Children′s Hospital, Zhejiang University School of Medicine from August 2020 to December 2023 were collected and retrospectively analyzed.The patients were divided into day surgery group and non-day surgery group according to whether they had discharged within 24 hours. t-test and Chi-square tests were used to compare the differences in clinical features, perioperative complications and prognosis between the two groups of patients.In addition, the satisfaction of the treatment effect was surveyed. Results:A total of 276 children were included in this study, with an age ranging from 6 to 154 months with a median of 34 months.The weight ranged from 6.2 to 63.2 kilograms, with a median of 13.5 kilograms.The operation time ranged from 23 to 90 minutes, with a median of 45 minutes.One hundred and thirty-five patients underwent day surgery and 141 patients underwent non-day surgery.The average age and average weight of the patients in the day surgery and non-day surgery groups was (43.7±30.8) months vs.(42.4±30.2) months and (15.0±6.4) kg vs.(14.8±6.9) kg, respectively.There was no statistically significant difference in age and weight between the two groups (all P>0.05).There was no difference in perioperative data and incidence of perioperative complications between the two groups (all P>0.05).However, the length of hospital stay of the day surgery group was significantly shorter than that of the non-day surgery group[(1.0±0) days vs.(2.5±0.9) days, t=-20.993, P<0.001], and the hospitalization cost of the day surgery group was also significantly lower than that of the non-day surgery group[(50 800±1 100) yuan vs.(53 500±3 900) yuan, t=-10.040, P<0.001].Both families of the two groups were satisfied with the treatment results, and there was no difference in satisfaction between the two groups ( χ2=0.501, P=0.479). Conclusions:The day surgery management model of Da Vinci robotic surgery for the treatment of pediatric patent ductus arteriosus is safe and feasible.To a certain extent, it can reduce the length of hospital stay, treatment costs, and treatment burden.

Objective:To explore the psychometric characteristics of the Chinese version of the health-related social capital scale.Methods:From March to May 2020, after the original scale was translated into Chinese following the Brislin improved translation model, 251 community-dwelling senior citizens aged 65 and above were selected by convenient sampling method. Data analysis was conducted using SPSS 22.0 and AMOS 22.0, including tests of significance, correlation analysis, exploratory factor analysis, and confirmatory factor analysis.Results:Exploratory factor analysis extracted three factors: social participation, social cohesion, and reciprocity, which accounted for a cumulative contribution rate of 61.72%. Confirmatory factor analysis showed that the three-factor model fitted well(χ 2/ df=1.22, RMSEA=0.04, CFI=0.98, GFI=0.93, IFI=0.98, TLI=0.97). Social capital was significantly correlated with perceived social support positively ( r=0.36, P<0.01), and with loneliness negatively ( r=-0.30, P<0.01). The three factors were significantly correlated with the total scale ( r=0.85, 0.50 and 0.52, respectively, all P<0.01). And correlations between the items of each factor were 0.24-0.55, 0.30-0.59, 0.44-0.70, respectively(all P<0.01). The Cronbach's α coefficients of the total scale and three factors were 0.74, 0.72, 0.65 and 0.62, respectively(all P<0.01), and their retest reliability were 0. 92, 0. 87, 0. 82 and 0. 96, respectively(all P<0.01). Conclusion:The Chinese version of health-related social capital scale conforms to the three-factor model with good reliability and validity, which can be used to assess the social capital status of community-dwelling older adults in China.

Objective:To explore the effect of problem-oriented evidence-based nursing on postoperative neurological complications in patients with aortic dissection aneurysm (ADA) .Methods:Using the convenient sampling method, a total of 82 ADA patients who underwent surgical treatment in Henan Provincial People's Hospital were selected as the research objects from September 2018 to May 2020. They were randomly divided into the study group and the control group, with 41 cases in each group. The control group was given routine nursing intervention, while the study group was given problem-oriented evidence-based nursing intervention based on routine nursing. The incidence of postoperative neurological complications in ADA patients was compared between the two groups.Results:The incidence of postoperative neurological complications in the study group was 4.88% (2/41) , lower than 24.39% (10/41) in the control group, and the difference was statistically significant ( P<0.05) . Conclusions:The problem-oriented evidence-based nursing model can effectively reduce the incidence of postoperative neurological complications in ADA patients.

Objective:To evaluate the compliance of colonoscopy screening and the detection rate of colorectal lesions with colonoscopy in urban areas of Henan province from 2013 to 2019.Methods:The study objects were derived from the Cancer Screening Program in Urban Henan Province, China. From October 2013 to October 2019, 282 377 residents, who had lived in the local area for more than three years, were recruited from Zhengzhou, Zhumadian, Anyang, Luoyang, Nanyang, Jiaozuo, Puyang and Xinxiang. The cancer risk assessment questionnaire was used to collect basic demographic characteristics, eating habits, living environment and habits, psychology and emotions, past disease history and family history of cancer, and women′s physiological and reproductive history. The cancer risk assessment model was used for evaluating the risk of colorectal cancer. The data related to colonoscopy screening was obtained from the participating hospitals. Chi-square test was used to analyze the compliance rate among different groups.Results:The 282 377 subjects were (55.26±8.68) years old, of which 44.80% (126 505) were males, and 67.63% (190 694) had junior/senior/tertiary education background. A total of 39 834 (14.11%) subjects were assessed to be at high risk for colorectal cancer, of which 7 454 took the following colonoscopy screening, yielding a participation rate of 18.71%. The screening rate was higher in those aged 50 to 54 (20.42%) and 55 to 59 (20.43%) years, and lowest in those aged 70 years and older (12.30%) ( P<0.001). A total of 17 colorectal cancer cases were detected, with a detection rate of 0.23% (17/7 454). Conclusion:Colonoscopy as a means of screening for colorectal cancer is helpful for early detection of colorectal lesions, but the participation rate is poor.

Objective:To observe the effect of early exercise intervention on the corticospinal tract of rats with cerebral infarction.Methods:Eighteen male Sprague-Dawley rats were randomly divided into a sedentary group (SED), a 1 day later exercise group (1D) and a 1 week later exercise group (1W), each of 6. A modified Longa′s method was used to occlude the middle cerebral artery to model a stroke. Rats in the 1D and 1W groups started exercising 1 day and 1 week after the modeling, while those in the sedentary group were placed on a stationary treadmill for 30 minutes every day. Modified neurological severity scores (mNSSs) were used to quantify neurological functioning after 1, 4 and 8 weeks. Magnetic resonance imaging was used to calculate the infarct volume ratio, and diffusion tensor imaging was used to detect the fractional anisotropy ratio (rFA) of the corticospinal tract for correlation with the mNSS scores. The corticospinal cord′s morphology was observed using DTT.Results:After 1 week the average mNSS score of the 1D group was significantly lower than the other two groups′ averages. At 4 weeks the average mNSS scores of both the 1D and the 1W group were significantly lower than the sedentary group′s average. At 8 weeks the 1D group′s average mNSS score was significantly lower than those of the other two groups, while that of the 1W group was significantly lower than the sedentary group′s average. At 1 and 4 weeks after modeling the average infarct volume ratio in the 1D group was significantly lower than those of the other groups. By 4 weeks the average infarct volume ratio of the 1W group was significantly lower than that of the sedentary group, and by 8 weeks the average infarct volume ratios of both the 1D and 1W groups was significantly lower than that of the sedentary group. After 1 week the average rFA of the 1D group was significantly lower than that of the sedentary group, but by 4 weeks the averages of the 1D group and the 1W group were both significantly higher than the sedentary group′s average. At 8 weeks the 1D group′s average rFA was significantly above that of the 1W group and of the sedentary group, and that of the 1W group was significantly higher than that of the sedentary group. After 8 weeks the corticospinal tracts in the 1D group appeared to be more symmetrical than those of the other 2 groups. The rFA results correlated strongly with the mNSS scores ( r=-0.707). Conclusions:Exercise can promote corticospinal cord remodeling and improve neurological function after cerebral infarction, at least in rats. It should be started as early as possible.

Objective:To explore effects of four postures nursing on oxygen partial pressure, pain and comfort degree of affected limbs in patients with lower extremity atherosclerotic occlusive disease (LEAOD) .Methods:A total of 357 patients with LEAOD who were admitted in Henan Provincial People's Hospital of Henan University from March 2018 to February 2019 were selected as the research objects by convenient sampling. All patients were respectively treated with four postural nursing methods, including supine position, sitting position, lower limb ptosis position and lower limb elevation position. The differences in oxygen partial pressure, pain value and comfort level of patients in different posture nursing states were compared.Results:Among 357 patients, 106 patients had no pain. Compared with the other three positions, the oxygen partial pressure level of the lower limb elevated position was the lowest, and the pain score and comfort score were the highest. The differences among the groups were statistically significant ( P<0.01) . The oxygen partial pressure level of lower limb ptosis position was the highest, and the pain score and comfort score were significantly lower than the other three positions. The differences were all statistically significant ( P<0.01) . Among the four postures, the changes of oxygen partial pressure in sitting position and lower limb ptosis position were the most significant, and the differences were statistically significant ( Z=145.433, P<0.01) . Conclusions:In the nursing of supine position, sitting position, lower limb ptosis position and lower extremity elevation position, lower extremity ptosis position has a more obvious improvement effect on oxygen partial pressure, comfort degree and pain value of patients with LEAOD compared with the other three positions. However, long-term prolapse of the affected limbs can easily cause blood stasis and discomfort symptoms. Therefore, it is necessary to set a reasonable nursing method and time for the affected limbs according to the condition of patients.
