Objective: To investigate the association between overweight, obesity, central obesity and hypertension, so as to provide the basis for formulating targeted hypertension prevention and control strategies. Methods: Permanent residents aged ≥18 years were selected in Wenzhou City, Zhejiang Province from June 2023 to August 2024 by a multistage cluster random sampling method. Data on demographic information, lifestyle, height, weight, waist circumference (WC), blood pressure, and blood biochemical indicators were collected through questionnaire surveys, physical examinations, and laboratory tests. The prevalence of hypertension was calculated and standardized using the data of the Sixth National Population Census in 2010. Body mass index (BMI) was calculated to determine overweight and obesity, while WC was used to identify central obesity. The association between overweight, obesity, central obesity and hypertension were analyzed using multivariable logistic regression models. Results: A total of 38 593 residents were surveyed, including 19 481 (50.48%) males and 19 112 (49.52%) females. The median age was 46.00 (interquartile range, 26.00) years. The rates of overweight, obesity, and central obesity were 32.74% (12 634 individuals), 10.27% (3 963 individuals), and 27.87% (10 755 individuals), respectively. There were 11 813 cases of hypertension, with a prevalence and standardized prevalence of 30.61% and 24.41%, respectively. Multivariable logistic regression analysis showed that after adjusting for demographic information, lifestyle, diabetes and dyslipidemia, the likelihood of hypertension in the overweight and obesity groups was 1.927 (95%CI: 1.815-2.045) times and 3.724 (95%CI: 3.404-4.073) times that of the normal BMI group, respectively. The likelihood of hypertension in the central obesity group was 2.346 (95%CI: 2.214-2.486) times that of the normal WC group. The likelihood of hypertension in the central obesity only, overweight only, overweight with central obesity, obesity only and obesity with central obesity groups was 1.586 (95%CI: 1.391-1.809), 1.704 (95%CI: 1.582-1.835), 2.433 (95%CI: 2.254-2.626), 1.768 (95%CI: 1.424-2.194), and 4.466 (95%CI: 4.053-4.921) times that of the normal BMI and WC group, respectively. Conclusions Overweight, obesity and central obesity were all associated with hypertension among adult residents. The highest likelihood of hypertension was observed among adult residents with both general obesity and central obesity.

Objective:To detect the expression of microRNA (miR)-211-5p, erythropoietin hepatocyte kinase receptor B2 (EphB2) and erythropoietin hepatocyte kinase ligand B2 (ephrin B2) in spinal cord tissues as well as nerve cells after spinal cord injury (SCI), and to explore their mechanisms and effects on neurological recovery in SCI rats.Methods:The study was conducted from May 2020 to June 2021 using Sprague Dawley (SD) rats and PC12 cells. SD rats were divided into sham-operated group and SCI group of 30 rats each, and Basso-Beattie-Bresnahan (BBB) score were performed at different postoperative time points (1, 3, 7, 14, 21 and 28 d), and the relative expression of miR-211-5p and Eph/ephrin B2 mRNA was measured by quantitative real-time polymerase chain reaction (qPCR); the SCI rats were divided into recombinant lentiviral vector LV-miR-211-5p group (group A), empty lentiviral vector LV-eGFP (group B) and saline group (group C), with 15 rats in each group, respectively. The recombinant lentiviral vector, empty lentiviral vector and saline were injected on the cephalic and caudal sides of the spinal cord injury, and the relative expression of miR-211-5p and Eph/ephrin B2 mRNA in the spinal cord tissue was measured at 1, 7 and 14 d after surgery. In addition, a PC12 injury cell line model was established with 150 μmol/L hydrogen peroxide (H 2O 2), and the apoptosis rate and apoptosis-related proteins and contents of different cell lines were detected by flow cytometry and Western blot, respectively. MiR-211-5p was verified to target EphB2 by dual luciferase reporter gene. Results:The results of the animal experiments showed that at different postoperative time points, the miR-211-5p levels in the SCI group were lower than those in the SHAM group: 0.70 ± 0.03 vs. 1.00 ± 0.10, 0.60 ± 0.04 vs. 1.00 ± 0.05, 0.45 ± 0.10 vs. 1.00 ± 0.12, 0.30 ± 0.06 vs. 1.00 ± 0.15, 0.20 ± 0.05 vs. 1.00 ± 0.13, 0.10 ± 0.02 vs. 1.00 ± 0.07. In contrast, levels of Eph/ephrin B2 were higher in the SCI group compared to the SHAM group: 1.10 ± 0.05 vs. 1.00 ± 0.01, 1.80 ± 0.01 vs. 1.00 ± 0.08, 2.30 ± 0.01 vs. 1.00 ± 0.10, 2.60 ± 0.01 vs. 1.00 ± 0.05, 2.80 ± 0.01 vs. 1.00 ± 0.06, 3.00 ± 0.01 vs. 1.00 ± 0.07 and 1.20 ± 0.05 vs. 1.00 ± 0.02, 1.60 ± 0.01 vs. 1.00 ± 0.03, 2.10 ± 0.10 vs. 1.00 ± 0.01, 2.40 ± 0.11 vs. 1.00 ± 0.09, 2.70 ± 0.13 vs. 1.00 ± 0.05, 2.90 ± 0.12 vs. 1.00 ± 0.03 ( P<0.05). At 14 d after surgery, Group A exhibited higher BBB scores than Groups B and C: (14.0 ± 1.1) points vs. (8.0 ± 1.1) and (8.2 ± 1.2) points, while miR-211-5p levels were higher than those in Groups B and C: 1.90 ± 0.10 vs. 0.40 ± 0.01 and 0.50 ± 0.02, and Eph/ephrin B2 levels were lower than those in Groups B and C: 0.70 ± 0.10 vs. 1.80 ± 0.04 and 1.90 ± 0.06, 0.60 ± 0.03 vs. 2.00 ± 0.04 and 2.10 ± 0.05 ( P<0.05). Immunofluorescence staining showed that the levels of GAP-43 and synaptophysin in group A were higher than those in groups B and C at 14 d after surgery ( P<0.05). Cellular assays showed that overexpression of miR-211-5p inhibited the apoptosis rate of H 2O 2-induced PC12 cells and the expression of the apoptosis-related gene Cleaved-caspase3 ( P<0.05). Knockdown of miR-211-5p increased the apoptosis rate of H 2O 2-induced PC12 cells and the expression of the apoptosis-related gene Cleaved-caspase3 ( P<0.05). Dual luciferase reporter gene assay confirmed that EphB2 was a target gene of miR-211-5p and overexpression of EphB2 antagonized the inhibitory apoptosis effect of miR-211-5p on H 2O 2-induced PC12 cells. Conclusions:This study showed that miR-211-5p could promote neurological repair in SCI by inhibiting the expression of Eph/ephrin B2 signaling pathway, suggesting that using miR-211-5p as a target to inhibit Eph/ephrin B2 signaling pathway may have a protective effect on SCI.

Objective To investigate the effect of Yantiao Fang on apoptosis of intestinal epithelial cells in mice with acute gastrointestinal injury caused by sepsis by regulating the Rho/ROCK signaling pathway.Methods Seventy BALB/c mice were randomly divided into normal,sham,and model groups.Except for normal and sham groups,mice were subjected to cecal ligation and perforation to establish a mouse model of acute gastrointestinal injury caused by sepsis.The mouse models were randomly divided into model,Low,Medium,and High dose of Yantiao Fang,and ROCK inhibitor groups.Histopathological changes of the ileum were observed by HE staining.Serum levels of IL-1β,IL-6,TNF-α,and IL-10 were measured by ELISA.PCNA and Ki-67 expression was detected by immunohistochemistry.Cleaved caspase3 and Bax expression was detected by Western blot.ROCK and MLC mRNA expression in the ileum was measured by RT-qPCR.Results Compared with normal and sham groups,Chiu's pathological score,proinflammatory factor(IL-1β,IL-6,and TNF-α)levels,cleaved caspase3 and Bax protein expression,and ROCK and MLC mRNA levels were increased in the model group(P＜0.05).Moreover,anti-inflammatory mediator IL-10 and expression of PCNA and Ki-67 in the ileum were decreased in the model group(P＜0.05).Compared with the model group,histopathological changes of the ileum in all Yantiao Fang groups were improved by various degrees with the increase in dose.Chiu's pathological score,IL-1β,IL-6,and TNF-α serum levels,cleaved caspase3 and Bax protein expression,and ROCK and MLC mRNA levels were decreased in Yantian Fang groups(P＜0.05).The IL-10 level and expression of PCNA and Ki-67 in the ileum were increased in Yantian Fang groups(P＜0.05).Conclusions Yantiao Fang may inhibit apoptosis of intestinal epithelial cells in mice with acute gastrointestinal injury due to sepsis by regulating the Rho/ROCK signaling pathway,thereby alleviating intestinal tissue inflammation and ultimately preventing intestinal mucosal tissue injury.

Objective:To further explore the symptom experience and coping strategies of patients with multiple myeloma, so as to provide reference for the formulation of symptom management programs.Methods:Objective sampling method was used to conduct semi-structured in-depth interviews on 15 patients with multiple myeloma in Hematology Department of Nanjing Drum Tower Hospital from December 2021 to June 2022 and the model of symptom management theory was used as the framework to construct an interview outline. The Colaizzi 7-step analysis method was used to analyze data and extract themes.Results:Three main themes were summarized: symptom experience (obvious symptom perception, poor symptom assessment ability, negative symptom response); symptom management strategy (vague knowledge of symptom management, hope to get professional guidance, expect to get continuity of management); symptom management outcomes (recurrent anxiety, reordering, adaptive behavior).Conclusions:Patients with multiple myeloma have diverse and complex real symptom experience in different periods. Medical staff should pay attention to patients′ symptom response and coping needs and develop a systematic symptom management plan, so as to help them create better self-management and improve their quality of life.

Objective To explore the impact of Jiawei Taoren Chengqi Decoction on autophagy in rats with mechanical ventilation-induced lung injury(VILI)through adenylate-activated protein kinase(AMPK)/mammalian target of rapamycin(mTOR)signaling pathway.Methods Sixty SPF male rats were randomly grouped into the sham operation group,the model group,the low-dose Jiawei Taoren Chengqi Decoction group(TCM-L group,2.85 g/kg),the high-dose Jiawei Taoren Chengqi Decoction group(TCM-H group,8.55 g/kg)and the high-dose Jiawei Taoren Chengqi Decoction + AMPK inhibitor Compound C group(TCM-H+CC group,Jiawei Taoren Chengqi Decoction 8.55 g/kg+ Compound C 250μg/kg),12 in each group.Oxygenation index(OI)was measured immediately after intubation and at 1 h,2 h and 4 h after mechanical ventilation.Bronchoalveolar lavage fluid(BALF)was collected after mechanical ventilation,levels of tumor necrosis factor(TNF)-α,interleukin(IL)-1β and IL-18 in BALF were detected by enzyme-linked immunosorbent assay(ELISA).Rats were sacrificed,and lung tissue was taken to measure the wet/dry weight(W/D)ratio.HE staining was used to observe pathological changes of lung tissue in each group of rats.Lung injury scores were carried out.Morphology of alveolar epithelial cells was observed by transmission electron microscopy.RT-qPCR was applied to detect mRNA expression levels of AMPK and mTORC1 in rat lung tissue.Western blot assay was applied to detect expression levels of AMPK,p-AMPK,mTORC1,p-mTORC1 and autophagy-related proteins in rat lung tissue.Results Compared with the sham group,the pathological damage of lung tissue was serious,lung W/D,levels of TNF-α,IL-1β and IL-18 in BALF,lung injury score,mTORC1 mRNA expression level,and p-mTORC1 protein expression were increased in the model group(P＜0.05).OI values at 2 h and 4 h of mechanical ventilation,AMPK mRNA expression level,p-AMPK,LC3-II/LC3-I and Beclin-1 protein expression in lung tissue were decreased(P＜0.05).Compared with the model group,the pathological damage of lung tissue was alleviated in the Chinese medicine-H group,and the trend of changes in related indexes was opposite to the above(P＜0.05).Autophagosomes in alveolar epithelial cells were increased.Compound C attenuated the protective effect of Jiawei Taoren Chengqi Decoction on VILI rats(P＜0.05).Conclusion Jiawei Taoren Chengqi Decoction may promote autophagy and reduce VILI in rats by activating AMPK/mTOR signaling pathway.

Objective:To explore the correlation between nurses′ workplace adaptability, moral dilemma and resilience after suffering workplace violence in emergency department, in order to provide reference about improving the workplace adaptability and formulating intervention.Methods:A cross-section survey was conducted, we selected 248 nurses who had suffered workplace violence in the emergency department of five tertiary hospitals in Qingdao from January 2022 to January 2023 by convenient sampling method, and used self-designed general information questionnaire, moral dilemma scale, resilience evaluation scale for medical staff and nurses′ workplace adaptability scale to conduct a questionnaire survey on nurses who had suffered workplace violence, and found out the factors affecting their workplace adaptability.Results:The score of workplace adaptability of 248 nurses who had suffered workplace violence was (39.37 ± 12.77) points. Univariate analysis showed that education, length of emergency service, department or social part-time job, professional title, number of night shifts and sleep condition were the influencing factors of workplace fitness for emergency nurses ( t/ F values were -12.72 to 132.15, all P<0.05). The correlation analysis showed that the nurses′ workplace adaptability after workplace violence was negatively correlated with the scores and total scores of all dimensions of moral dilemma ( r values were -0.725 to -0.194, P<0.05), and positively correlated with the scores and total scores of all dimensions of resilience ( r values were 0.135 to 0.732, P<0.05). Multi-factor results showed that education background, department/social part-time job, working years, professional title, sleep status, moral dilemma and resilience were the influencing factors of nurses′ workplace adaptability after workplace violence ( t values were -9.25 to 15.25, P<0.05). Conclusions:Nurses with specialized education, emergency service for 1-3 years, no department/social part-time job, primary professional title, sleep disorder, higher degree of moral dilemma and low level of resilience have low occupational adaptability. Nursing managers should focus on such nurses and improve their occupational adaptability.

Objective:To summarize the situation of dead newborns and their parents after parents gave up treatment, and analyze the reasons and emotional needs of parents who gave up treatment, so as to provide reference for reducing neonatal mortality and negative emotions of parents.Methods:A retrospective study was conducted to collect the data of neonates and mothers who died after giving up treatment reported in Hunan Children′s Hospital from January 2019 to December 2021. The general information, perinatal risk factors, and the incidence of in-hospital diseases were analyzed. Then, semi-structured interviews were conducted with parents of newborns who died after giving up treatment from February to December 2021. Understand why parents give up treatment and their emotional needs.Results:A total of 172 newborns died after giving up were included in the analysis, including 103 males (59.88%) and 74 premature infants (43.02%); Umbilical cord, placenta and amniotic fluid abnormalities were 21 cases (12.21%), 39 cases (22.67%) and 25 cases (14.53%), respectively. Birth asphyxia was 31 cases (18.02%), including severe asphyxia in 18 cases (10.46%); There were 21 (12.21%), 35 (20.35%) and 30 (17.44%) cases of maternal infection in the third trimester, hypertension in pregnancy and diabetes in pregnancy, respectively. The top three causes of death were septicemia (18.02%), congenital malformation (16.86%) and severe pneumonia (10.47%). The main reason why parents give up treatment was that the child′s disease was critical and irreversible, and parents had strong emotional needs for hospice care in their hearts.Conclusions:There are many high risk factors of perinatal death of newborns after giving up treatment. Sepsis is the primary cause of death, and strengthening perinatal health care is fundamental. Parents have a strong demand for hospice care, so it is of practical significance to implement family-centered hospice care model for such special newborns.

【Objective】 To explore the predictive value of preoperative liver function for massive blood transfusion (MBT) in patients undergoing ascending aorta surgery. 【Methods】 Data from 238 patients undergoing ascending aorta surgery in the Department of Cardiovascular Surgery at The Affiliated Lihuili Hospital of Ningbo University were collected. Preoperative liver function tests were performed for all patients. Based on the perioperative transfusion volumes of red blood cell suspension, patients were divided into the MBT group, non-MBT group, and no blood transfusion (NBT) group. Clinical data during the perioperative period were compared among different groups. Receiver operating characteristic curve (ROC curve) analysis was used to assess the predictive value of liver function indicators for MBT and determine cut-off values. 【Results】 Compared with the non-MBT group and NBT group, the MBT group showed statistically significant differences in preoperative levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), direct bilirubin (DBIL), and serum albumin (SA) (P<0.05). ROC curve analysis revealed that AST had the largest area under the curve (AUC) for predicting MBT, with a value of 0.723. ALT had the highest specificity for predicting MBT at 86.7%, and SA had the highest sensitivity at 89.7%. When AST >28.50 U/L, ALT >40.00 U/L, SA ≤34.55 g/L, and DBIL >4.25 μmol/L, there was a significant increase in the transfusion volume of various blood components and the incidence of MBT. 【Conclusion】 Preoperative liver function indicators (AST, ALT, SA, DBIL) have a moderate predictive value for MBT in patients undergoing ascending aorta surgery.
