Background::Hypertension and non-alcoholic fatty liver disease (NAFLD) share several pathophysiologic risk factors, and the exact relationship between the two remains unclear. Our study aims to provide evidence concerning the relationship between hypertension and NAFLD by analyzing data from the National Health and Nutrition Examination Survey (NHANES) 2017-2018 and Mendelian randomization (MR) analyses.Methods::Weighted multivariable-adjusted logistic regression was applied to assess the relationship between hypertension and NAFLD risk by using data from the NHANES 2017-2018. Subsequently, a two-sample MR study was performed using the genome-wide association study (GWAS) summary statistics to identify the causal association between hypertension, systolic blood pressure (SBP), diastolic blood pressure (DBP), and NAFLD. The primary inverse variance weighted (IVW) and other supplementary MR approaches were conducted to verify the causal association between hypertension and NAFLD. Sensitivity analyses were adopted to confirm the robustness of the results.Results::A total of 3144 participants were enrolled for our observational study in NHANES. Weighted multivariable-adjusted logistic regression analysis suggested that hypertension was positively related to NAFLD risk (odds ratio [OR] = 1.677; 95% confidence interval [CI], 1.159-2.423). SBP ≥130 mmHg and DBP ≥80 mmHg were also significantly positively correlated with NAFLD. Moreover, hypertension was independently connected with liver steatosis ( β = 7.836 [95% CI, 2.334-13.338]). The results of MR analysis also supported a causal association between hypertension (OR = 7.203 [95% CI, 2.297-22.587]) and NAFLD. Similar results were observed for the causal exploration between SBP (OR = 1.024 [95% CI, 1.003-1.046]), DBP (OR = 1.047 [95% CI, 1.005-1.090]), and NAFLD. The sensitive analysis further confirmed the robustness and reliability of these findings (all P >0.05). Conclusion::Hypertension was associated with an increased risk of NAFLD.

Objective:To investigate the status of postoperative sore throat and hoarseness in patients undergoing general anesthesia with double-lumen endotracheal intubation and analyze its influencing factors.Methods:Using the convenient sampling method, a total of 129 patients with double-lumen endotracheal intubation who underwent elective surgery in a Class Ⅲ Grade A general hospital in Wuhan in Hubei Province from July to December 2020 were selected as the research objects. The general information questionnaire, Visual Analogue Scale (VAS), Labial and Tongue Mucosa Scale and Hoarse Voice Scale were used to investigate the patients.Results:The incidence of sore throat in 129 patients with double-lumen endotracheal intubation at 1, 6, 24, 48 and 72 hours after surgery were 68.22%, 44.96%, 76.74%, 64.34% and 48.84%, respectively. Among them, the incidences of sore throat in resting state were respectively 10.9%, 6.2%, 1.6%, 0 and 1.6%, incidences of sore throat in swallowing state were respectively 18.6%, 8.5%, 3.1%, 0 and 0, and the incidences of hoarseness were respectively 66.67%, 45.74%, 78.29%, 65.89% and 48.84%. There were statistically significant differences in the occurrence of hoarseness in patients of different ages and preoperative fasting time 1 hour after extubation ( t=2.499, 2.106; P<0.05). The VAS scores of patients with hoarseness in resting state and swallowing state were higher than those in patients without hoarseness, and the differences were statistically significant ( t=3.688, 2.818; P<0.01). Correlation analysis showed that hoarseness was negatively correlated with the condition of lip and tongue mucosa ( r=-0.309, P<0.01) . Conclusions:The incidence of postoperative throat pain in patients undergoing general anesthesia with double-lumen endotracheal intubation is high. With the extension of time, pain can be gradually relieved. The self-healing effect of hoarseness over time is not ideal. Advanced age, prolonged water fasting before operation and dry lip and tongue mucosa are the influencing factors of postoperative sore throat. Early identification and effective measures should be given in nursing evaluation to reduce the occurrence of postoperative sore throat.

Objective:To explore the mediating effect of perceived professional benefits between the humanistic literacy and spiritual care competence among oncology nurses.Methods:From September to October 2022, convenience sampling was used to select 354 oncology nurses from 11 ClassⅢ Grade A hospitals in Sichuan Province, Guangdong Province, and Hubei Province as the research subject. A survey was conducted on oncology nurses using the General Information Questionnaire, Nurses' Perceived Professional Benefit Questionnaire, Nurses' Humanistic Literacy Scale, and the Chinese version of the Spiritual Care Competence Scale (SCCS) . Pearson correlation was used to analyze the relationship between nurses' humanistic literacy, perceived professional benefits, and spiritual care competence. AMOS 26.0 software was used to analyze mediating effects. A total of 354 questionnaires were distributed, and after excluding 7 unqualified questionnaires, 347 valid questionnaires were collected, with a valid response rate of 98.02%.Results:Among 347 oncology nurses, the score of the Chinese version of SCCS was (77.60±19.04) . The total score of the SCCS was positively correlated with the total scores of the Nurses' Humanistic Literacy Scale, the Nurses' Perceived Professional Benefit Questionnaire, and scores of all dimensions, with statistically significant differences ( P<0.01) . Bootstrap test showed that the mediating effect of perceived professional benefits among oncology nurses between humanistic literacy and spiritual care competence was 0.284 [95% CI (0.408, 0.860) ] , accounting for 50.90% of the total effect. Conclusions:The perceived professional benefits of oncology nurses play a partial mediating role between humanistic literacy and spiritual care competence. We should strengthen training on the humanistic literacy of oncology nurses, enhance their perceived professional benefits, form a virtuous cycle of employment, and thereby improve their spiritual care competence.

ObjectiveTo investigate the key compounds affecting the irritation and to clarify the effect of heating and the addition of ginger juice as the auxiliary material during the processing on the irritation of Magnoliae Officinalis Cortex(MOC) by comparing the irritation and composition of volatile oil in MOC and its different processed products. MethodVolatile oil in raw products, water-processed products, ginger-dried products, ginger-fried products(the amounts of ginger were 10%, 50%, respectively) of MOC were extracted by steam distillation and subjected to rabbit eye irritation experiment, and the volatile components of each sample were detected by gas chromatography-mass spectrometry(GC-MS). Principal component analysis(PCA)and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to analyze the data of each sample by SIMCA 14.1. The relative contents of different processed products were compared two by two with those of and raw products or ginger-fried products, and the markers that might be related to the irritation were sorted out according to the principles of variable importance in the projection(VIP) value >1 and P<0.05, and the factors influencing the differences in irritation were analyzed. ResultCompared with the blank group, the administration groups all had irritation to the eyes of rabbits, and the degree of irritation was in the order of raw products>water-processed products>ginger-dried products>ginger-fried products(10%)>ginger-fried products(50%). The results of PCA and OPLS-DA showed that there were differences in the volatile oil from raw products and different processed products. According to VIP value>1 and P<0.05, and combined with the results of eye irritation experiment, ten volatile compounds related to irritation changes were screened out. Among them, cis-cinnamaldehyde was only detected in raw products, the relative contents of β-caryophyllene, (+)-delta-cadinene, α-humulene, γ-muurolene, (-)-isoledene and citral all increased to different degrees, the contents of p-cymene, 1(10)-4-cadinadien-15-ol and β-eudesmol all decreased to different degrees. ConclusionThe irritation of MOC is reduced after heating and processing with ginger juice, and the synergistic effect of both is more effective for reducing irritation. Among the differential markers associated with changes in irritation, the increase in the relative content of citral is closely related to the addition of ginger juice, while the decrease in the relative contents of cis-cinnamaldehyde, p-cymene, 1(10)-4-cadinadien-15-ol is related to heating, and the changes of other components may be related to the synergistic effect of heating and ginger juice.
