Objective To explore the clinical effect of nursing under nutritional risk assessment(NUNRA)in patients with mandibular tumors undergoing fibula musculocutaneous flap grafting.Methods A total of 120 patients with mandibular tumor who underwent fibula musculocutaneous flap grafting in the Department of Otolaryngology of the First Affiliated Hospital of Nanjing Medical University from January 2018 to December 2022 were selected as research objects.They were numbered in the order of 1-120 and divided into control group and intervention group according to odd and even numbers,with 60 cases in each group.The control group received routine rehabilitation nursing.The intervention group were given NUNRA.The mandibular joint function,nutritional index and complications were compared between the two groups before intervention and 14 d after intervention.Results There was no significant difference in the mandibular joint function or nutrition index between the two groups before intervention(P>0.05).After 14 d of intervention,the scores of mandibular movement,joint pressing diagnosis and muscle pressing diagnosis of the intervention group were higher than those of the control group(P<0.05);the nutritional indexes,such as transferrin(TRF),albumin(ALB),total protein(TP)and prealbumin(PAB)in the intervention group were superior to those in the control group(P<0.05);and the incidences of gastrointestinal disorders,infection,wound swelling and malnutrition in the intervention group were lower than those in the control group(P<0.05).Conclusion NUNRA can improve mandibular function and nutrition index and reduce the incidences of postoperative complications in patients with mandibular tumors undergoing fibula musculocutaneous flap grafting.

Objective: To investigate the e-cigarette use and its influencing factors among middle school students in Ningbo City, Zhejiang Province, so as to provide insights into e-cigarette control among adolescents. Methods: Students of junior high schools, high schools and vocational high schools in Ningbo City were sampled using a multi-stage stratified cluster random sampling method from September to October 2021. Students' general information, cigarette and e-cigarette use and e-cigarette advertising exposure were collected using 2021 China Youth Tobacco Survey Questionnaire, and proportions of e-cigarette current use and attempt to use were analyzed. Factors affecting the attempt to use e-cigarettes were identified using a multivariable logistic regression model. Results: Totally 1 591 questionnaires were allocated, and 1 574 valid questionnaires were recovered, with an effective rate of 98.93%. The respondents included 863 males (54.83%) and 711 females (45.17%); 787 junior high school students (50.00%), 535 high school students (33.99%) and 252 vocational high school students (16.01%). The proportion of current e-cigarette use was 1.91% and the proportion of attempt to use e-cigarettes was 6.61%. Multivariable logistic regression analysis identified males (OR=2.544, 95%CI: 1.438-4.501), living in rural areas (OR=2.084, 95%CI: 1.195-3.634), having close friends who were smokers (OR=4.828, 95%CI: 2.936-7.940), witnessing teachers smoking at school (OR=2.766, 95%CI: 1.642-4.659), e-cigarette advertising exposure (OR=2.155, 95%CI: 1.315-3.532), current cigarette use (OR=9.365, 95%CI: 2.610-33.603) and attempt to use cigarettes (OR=7.519, 95%CI: 4.115-13.737) as promoting factors for the attempt to use e-cigarette. Conclusions There are e-cigarette use behaviors among middle school students in Ningbo City. Having teachers or close friends who were smokers, cigarette use behaviors and e-cigarette advertising exposure may increase the risk of attempt to use e-cigarettes among middle school students.

Objective: To investigate the attitude and behaviors towards tobacco control among civil servants in smoke-free governments of Ningbo City, so as to provide insights into the construction of smoke-free governments. Methods: Ten governments were randomly sampled from city-level and county/district-level smoke-free governments in Ningbo City using a stratified random sampling method, and 10 civil servants were sampled from each government using a convenient sampling method. Participants' demographics, attitude and behaviors towards tobacco control and second-hand smoke exposure were collected using a self-designed questionnaire and descriptively analyzed. Results: A total of 1 100 civil servants were recruited, including 466 men (42.36%) and had a mean age of (39.02±9.38) years. There were 1 005 participants favoring “civil servants should refuse smoking firstly” (91.36%), 1 058 participants favoring “governments should build a smoke-free environment firstly” (96.18%), 1 075 participants favoring “smoking should be completely banned in any indoor public places” (97.73%), 913 participants thinking that smoking should be completely banned in any indoor public places (83.00%) and 813 participants thinking that tobacco control regulations are implemented satisfactorily in their workplaces (73.91%). The overall prevalence of current smoking was 11.91% among participants, and the prevalence of current smoking was 28.11% among male participants. Among all current smokers, 84 attempted to quit smoking (64.12%), and 89 had willingness or plans to quit smoking (67.94%). The proportion of second-hand smoke exposure in workplaces was 40.97% among non-smokers in the past one week. Conclusions The civil servants in Ningbo City has correct awareness of smoke-free governments, active attitudes towards tobacco control and low prevalence of smoking. However, smoke-free regulations remain to be improved and long-term tobacco control mechanisms remain to be created in governments in Ningbo City

Methods: The epidemiological data of tobacco use among adolescents in Ningbo City in 2021 were collected, including demographics, tobacco use, parents' and close friends' smoking status, secondhand smoke exposure and tobacco advertisement exposure. The intention to smoke, current smoking, secondhand smoke exposure and tobacco advertisement exposure were descriptively analyzed among middle school students, and the factors affecting intention to smoke, current smoking were identified using a multivariable logistic regression analysis. Results: Totally 1 591 questionnaires were allocated to middle school students, and 1 574 valid questionnaires were recovered, with an effective recovery rate of 98.93%. The respondents included 787 junior high school students, 535 high school students and 252 vocational high school students, and the prevalence was intention to smoke and current smoking was 6.73% and 1.78% among the respondents, respectively. Multivariable logistic regression analysis identified boys (OR=2.398, 95%CI: 1.466-3.922), high school students (OR=2.051, 95%CI: 1.212-3.470), vocational high school students (OR=2.011, 95%CI: 1.108-3.650), more than 100 yuan disposable pocket money per week (OR=2.534, 95%CI: 1.301-4.935) and close friends' smoking (OR=4.310, 95% CI: 2.755-6.757) as risk factors of intention to smoke, and boys (OR=12.420, 95%CI: 1.645-93.753), close friends' smoking (OR=11.628, 95%CI: 4.348-31.250) and parents' smoking (OR=2.667, 95%CI: 1.029-6.897) as risk factors of current smoking among middle school students. The prevalence of secondhand smoke exposure and tobacco advertisement exposure was 76.43% and 51.65%, and television/video/cinema was the most likely route of tobacco advertisement exposure (42.06%). Conclusions The prevalence of intention to smoke and current smoking is low among middle school students in Ningbo City; however, the proportions of exposure to secondhand smoke and tobacco advertisement are relatively high. Tobacco control interventions are recommended to be intensified targeting high-risk populations, such as vocational high school students.

Objective: To analyze the prevalence of smoking among adults in Ningbo City from 2018 to 2021, so as to provide the scientific evidence for improving the tobacco control policy and evaluating the effectiveness of the tobacco control policy. Methods: The permanent residents at ages of 15 to 69 years were recruited from 10 counties ( districts ) in Ningbo City using the stratified multistage random sampling method from 2018 to 2021, and subjects' demographic features, smoking and secondhand smoke exposure were collected using the National Questionnaire for Surveillance on Healthy Literacy and Tobacco Epidemic in Chinese Residents. All data were standardized to the Sixth National Population Census in 2010. The prevalence of smoking, smoking cessation and exposure to secondhand smoke and the trends for the prevalence were estimated among adults in Ningbo City from 2018 to 2021. Results: A total of 6 581, 6 340, 6 380 and 6 400 valid questionnaires were recovered from 2018 to 2021, and the effective recovery rates were 99.20%, 97.46%, 97.76% and 98.02%, respectively. The respondents had male to female ratios of 1∶1.05, 1∶1.07, 1∶1.05 and 1∶1.14, and had urban-rural population ratios of 1∶0.75, 1∶0.62, 1∶0.60 and 1∶0.78 from 2018 to 2021, respectively. The prevalence of current smoking was 21.99%, 21.42%, 22.07% and 20.30%, and the standardized prevalence was 22.03%, 20.12%, 21.33% and 19.38% from 2018 to 2021, respectively, appearing no significant changing trend ( χ2trend=3.751, P=0.053 ). The prevalence of current smoking was significantly higher among rural residents than among urban residents, and higher in men than in women ( all P<0.05 ). The prevalence of smoking cessation was 24.44%, 27.11%, 26.97% and 29.59%, and the standardized prevalence was 21.96%, 26.90%, 24.92% and 28.38% from 2018 to 2021, appearing a tendency towards a rise ( χ2rend=11.193, P=0.001 ). The prevalence of exposure to secondhand smoke was 52.40%, 50.18%, 48.99% and 44.58%, and the standardized prevalence was 54.08%, 51.45%, 49.95% and 46.76% from 2018 to 2021, showing a tendency towards a decline ( χ2rend=62.094, P<0.001 ) . Conclusions The prevalence of current smoking was approximately 20% among adults in Ningbo City from 2018 to 2021, with a tendency towards a decline in the prevalence of exposure to secondhand smoke and a tendency towards a rise in the prevalence of smoking cessation. Rural male residents are key targets for tobacco control.

Objective: To investigate the effect of nimodipine combined with cerebrospinal fluid replacement on hemoglobin concentration, Toll-like receptor 4 (TLR4) expression level and cerebral vasospasm (CVS) in patients with CVS after aneurysmal subarachnoid hemorrhage (aSAH). Methods: One hundred and twenty patients with CVS after aSAH admitted to the Department of Neurosurgery, the Sixth Medical Center of PLA General Hospital from May 2013 to May 2015 were selected. They were randomly divided into control group and observation group (n=60 in each group). The control group received conventional treatment and nimodipine infusion after embolization of the aneurysms, and the observation group underwent cerebrospinal fluid replacement by lumbar puncture on this basis. The clinical efficacy, Glasgow Coma Scale (GCS) scores, hemoglobin concentration and TLR4 expression levels before and after treatment, and adverse reactions were compared between the two groups. Results: One month after treatment, the improvement rate of vasospasm in the observation group was significantly higher than that in the control group (86.7% vs. 60.0%; χ²=9.590, P=0.002). Three months after the treatment, the good rate of clinical outcome (the modified Rankin Scale score 0-2) was significantly higher than that of the control group (88.3% vs. 58.3%; χ² =13.807, P<0.001). Before treatment, there were no significant differences in hemoglobin concentration and TLR4 expression levels between the two groups; after treatment, the hemoglobin concentration and TLR4 expression levels of both groups were significantly reduced (P<0.05). Compared with the control group, the hemoglobin concentration (119.9±19.8 g/L vs. 137.6±17.8 g/L; t=3.270, P=0.001) and TLR4 expression level (2.5±1.2 vs. 4.5±1.5; t=8.060, P<0.001) in the observation group decreased more significantly. Multivariate logistic regression analysis showed that hypertension (odds ratio [OR] 5.19, 95% confidence interval [CI] 2.31-6.71), hyperlipidemia (OR 2.70, 95% CI 1.93-4.86), previous history of stroke or transient ischemic attack (OR 6.29, 95% CI 3.23-7.32), smoking (OR 4.80, 95% CI 2.18-6.19), and the TLR4 expression level before treatment (OR 3.28, 95% CI 2.87-6.93) were independently correlated with the lack of improvement in CVS, and cerebrospinal fluid replacement was independently correlated with CVS improvement (OR 0.40, 95% CI 0.14-0.89). There was no significant difference in the incidence of adverse reactions such as blood pressure drop, obstructive hydrocephalus and gastrointestinal hemorrhage between the observation group and the control group, but the incidence of delayed CVS (13.3% vs. 36.7%; χ²=7.510, P=0.006) and secondary cerebral infarction (8.3% vs. 31.7%; χ²=8.800, P=0.003) in the observation group were significantly lower than those of the observation group. Conclusion Nimodipine infusion combined with cerebrospinal fluid replacement by lumbar puncture affected the hemoglobin concentration and TLR4 expression levels, improved the CVS improvement rate, and significantly improved the clinical outcome in patients with CVS after aSAH.

Objective? To explore the effects of Omaha system-based nursing intervention on patients after percutaneous coronary intervention (PCI). Methods? Totally 200 patients receiving PCI in Ningbo First Hospital from February 2016 to November 2017 were selected using convenient sampling and divided into the control group (n=100) and the observation group (n=100) according to the random number table. Patients in the control group received conventional nursing care, while patients in the observation group received nursing care based on Omaha system. The incidence of postoperative vascular complications was evaluated between the two groups. Self-Depression Scale (SDS), Self-Anxiety Scale (SAS) and the nursing satisfaction questionnaire were used to evaluate the effects of intervention. Results? The incidence rate of postoperative vascular complications was lower in the observation group than in the control group (P＜ 0.05); the SAS and SDS scores of the observation group were lower than those of the control group (P＜0.05); and the satisfaction at discharge of the observation group was higher than that of the control group (P＜ 0.05). Conclusions? Omaha system-based nursing interventions can reduce the incidence rate of postoperative vascular complications, ameliorate patients' negative emotions and improve their satisfaction, which is worth promoting in clinical practice.
