Objective To investigate the association between lifestyle and risk of heart disease and diabetes in the elderly population in Xi'an City. Methods From January 2021 to January 2024, a staged cluster sampling method was used to investigate the lifestyle and the occurrence of heart disease and diabetes in elderly population aged 60 years and above in the communities of Xi'an. Multivariate logistic regression was used to analyze the relationship between lifestyle and the risk of heart disease and diabetes. Results A total of 413 elderly people were investigated, of which 31.96% had heart disease, 27.12% had diabetes, and 10.90% had diabetes with heart disease. Multivariate logistic regression analysis revealed that age, BMI, family history, sweet food preference, smoking, and sitting and lying for a long time were risk factors for diabetes in the elderly population (P<0.05). Age, BMI, family history, history of diabetes, preference for salted products, smoking, drinking, and sitting and lying for a long time were risk factors for heart disease in the elderly population (P<0.05). Conclusion The incidence rates of heart disease and diabetes are high in the elderly population in Xi'an City. The risk of diabetes is related to unhealthy lifestyles such as sweet food preference, smoking, and sitting and lying for a long time, while heart disease is related to unhealthy lifestyles such as preference for salted products, smoking, drinking, and sitting and lying for a long time.

In recent years, potato scab caused by Streptomyces scabies is aggravating year by year, becoming an industrial problem urgently to be resolved. Screening antagonistic bacteria with good inhibitory effect and wide adaptability is the main measure to realize effective prevention and control of the disease. This study screened three strains of antagonistic bacteria DXT2-4, T2-1 and 21-14 with good inhibitory effect on S. scabies by using plate standoff test, and identified them as Bacillus altitudinis, Bacillus safensis and Bacillus pumilus, respectively, based on morphological characteristics, physiological and biochemical properties, and 16S rRNA gene sequences. DXT2-4, T2-1 and 21-14 showed the pot control efficacy of 68.83%, 48.57%, and 57.14%, respectively. The field control efficacy of the three strains was 59.48%, 34.58% and 51.75% in Hulun Buir, Inner Mongolia Autonomous Region and 55.14%, 36.05%, and 49.05% in Huizhou, Guangdong. The three strains could grow normally in the media with pH 1.0-13.0 and with 1%-11% NaCl, and they had inhibitory effects on Rhizoctonia solani, Verticillium dahliae, Alternaria solani, and Fusarium oxysporum. The indole-3-acetic acid yields of DXT2-4, T2-1, and 21-14 were 2.23, 1.11, and 1.67 mg/L, respectively. DXT2-4 and 21-14 demonstrated strong abilities to solubilize phosphorus. The optimal carbon source, nitrogen source, and inorganic salt for fermentation of strain DXT2-4 were 2% molasses+2% corn starch, 2% soybean meal, and 0.3% MgSO₄·7H₂O, respectively. These findings suggest the three strains of bacteria can efficiently inhibit the growth of S. scabies and have strong environmental adaptability. Particularly, DXT2-4 has the best effects of inhibiting the disease and promoting plant growth, showing a high development value and broad application prospects, this is of great significance for promoting sustainable potato production and ensuring the environmentally sound utilization of resources.

Objective:To identify the factors associated with the care needs of the older adults aged 65-105 by age groups,and to compare these factors across different age groups.Methods:A total of 12 244 older adults from the Chinese longitudinal healthy longevity survey(CLHLS)conducted in 2018 were included in the analyses.The participants were categorized into three age groups:young-old(aged 65-79),middle-old(aged 80-89),and oldest-old(aged 90-105).The level of disability was measured by the disability index(DI)in four dimensions,reflecting their care needs.Potential factors associated with care needs were selected based on the health ecological model(HEM),including per-spectives of personal characteristics,behavioral characteristics,interpersonal network,living and working conditions,and policy environment.Multifactor analysis was performed using multinomial Logistic regres-sion.Results:Among China's 12 244 older adults,43.4％had medium or high care needs.Factors for higher care needs of older adults included higher age,higher number of chronic diseases,no exercise habit,excessive sleep duration(≥9 h/d),depressive tendency,living with children or spouse,and un-educated(all P＜0.05).In addition,the young-old group who were past smokers(OR=2.009,95％CI:1.019-3.959),were past drinkers(OR=2.213,95％CI:1.141-4.291),and reported self-per-ceived poverty(OR=2.051,95％CI:1.189-3.540),had higher level of care needs.The middle-old group who were female(OR=1.373,95％CI:1.038-1.817),never drank alcohol(OR=1.551,95％CI:1.059-2.269),and were lack of medical insurance(OR=1.598,95％CI:1.053-2.426),and had higher level of care needs.The oldest-old group who were female(medium care needs vs.low care needs:OR=1.412,95％CI:1.062-1.878;high care needs vs.low care needs:OR=1.506,95％CI:1.137-1.993),reported self-perceived poverty(OR=2.064,95％CI:1.282-3.323),and were lack of medical insurance(OR=1.621,95％CI:1.148-2.291),and had higher level of care needs.Conclusion:The identical factors associated with care needs across different age groups include age,chronic disease,exercise,sleep,depression,living arrangement,and education.Smoking,alcohol consumption,and economic status are specific factors among the young-old group of the older adults,while gender and medical insurance are specific factors among the middle-old and the oldest-old group of the older adults.We recommend conducting prospective cohort studies and intervention studies among specific age groups on the above factors to provide reliable evidence for policy formulation.

To summarize the nursing experience of a pediatric patient who underwent hematopoietic stem cell transplantation following liver transplantation for erythropoietic protoporphyria,several key nursing points were identified.These included implementing plasma exchange to prevent liver failure,employing light-avoidance therapy to reduce photosensitivity,enhancing skin and mucosal care to minimize bacterial colonization,and strengthening caregiver management to prevent cross-infection.After hematopoietic stem cell transplantation,the main focus of nursing care shifted towards drug management to mitigate liver damage,closely monitoring the patient's condition for potential nervous system lesions,implementing effective diarrhea management strategies to prevent perianal infection,prioritizing psychological support in order to alleviate negative emotions experienced by the patient,and providing individualized health education and follow-up management plans aimed at promoting rehabilitation.Because of meticulous nursing provided by a dedicated multidisciplinary team,the child showed significant improvement within 34 days post-transplantation and continued recovering well during outpatient follow-up visits conducted 4 months after hospital discharge.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the changes of liver pathology and its influencing factors in patients with chronic hepatitis B viral (HBV) infection and low level of serum alanine aminotransferase (ALT).Methods:The clinical data of 135 with chronic HBV infection patients, in whom the serum ALT levels were less than two times of the upper limit of normal (ULN), were collected from the Affiliated Hospital of Medical School of Ningbo University and the First Affiliated Hospital, Zhejiang University School of Medicine during July 2017 and July 2019. The result of hepatic histological examination was reviewed, and the risk factors of obvious liver inflammation (G≥2) or fibrosis (S≥2) in patients were analyzed with Logistic regression analysis.Results:The pathological examination of liver tissue revealed G≥2 or S≥2 in 52 cases (38.5%). The univariate analysis showed that age, family history of HBV infection, ALT 1-<2×ULN, aspartate aminotransferase(AST)≥1×ULN, low platelet count(PLT)and prolongation of prothrombin time(PT)were associated with G≥2 or S≥2 in chronic HBV infection patients with low level ALT ( P<0.05 or <0.01). Multivariate Logistic regression analysis showed that age( OR=1.052, 95% CI 1.007-1.100), family history of HBV infection( OR=5.448, 95% CI 2.191-13.548)and AST( OR=1.042, 95% CI 1.005-1.081)were independent risk factors of G≥2 or S≥2 in chronic HBV infection patients with low level ALT ( P<0.05 or <0.01). Conclusion:Age, family history of HBV infection and AST level can be used to judge the severity of liver pathological changes and necessity of antiviral treatment for patients with chronic HBV infection having ALT<2×ULN.

Objective:To explore the predictive value of China Nanjing persistent vegetative state scale (CNPVSS) on the curative effect of the patients with chronic disorder of consciousness, by analyzing the curative effect of the rehabilitation treatment combined with hyperbaric oxygen (HBO) for patients with chronic disorder of consciousness.Methods:A total of 48 patients with chronic disorder of consciousness admitted to Nanjing Zijin Hospital to receive rehabilitation treatment combined with HBO from the September of 2016 to the May of 2019 were selected according with the analytical criteria. Before the treatment, the patients were evaluated by CNPVSS and received electroencephalogram (EEG) and evoked potentials (EPs) examinations. The patients′ consciousness was evaluated again before discharge, the results of CNPVSS and electrophysiological examinations were recorded, and the correlation between the results and the changes of the consciousness was analyzed statistically.Results:The results of CNPVSS was positive correlated with near-term curative effect ( r=0.401, P=0.005); the rate of awakening after treatment was 46.2% among those who were scored as minimally conscious state (MCS) by CNPVSS; the rate of awakening after treatment was 17.1% among those who were at vegetative state (VS) or in a coma; the rate of awakening after treatment of the MCS patients was higher than those of the patients at VS or in a coma ( χ2=4.255, P=0.039). The recordings of right somatosensory evoked potentials (SSEPs) N20 was positive correlated with curative effect ( r=0.312, P=0.031); and the left visual evoked potentials (VEPs) V100 was positive correlated with curative effect ( r=0.285, P=0.049). There were no statistical significance found between other electrophysiological recordings with curative effect. Conclusion:CNPVSS can be an important tool to predict the outcome of the rehabilitation treatment combined with HBO for the patients with chronic disorder of consciousness, and the recordings of SSEPs and VEPs also are of a certain reference value in predicting the prognosis.
