Tanshinone ⅡA improves Alzheimer’s disease via RNA nuclearenriched abundant transcript 1/microRNA-291a-3p/member RAS oncogene family Rab22a axis

BACKGROUND Alzheimer’s disease(AD)is a neurodegenerative condition characterized by oxidative stress and neuroinflammation.Tanshinone ⅡA(Tan-ⅡA),a bioactive compound isolated from Salvia miltiorrhiza plants,has shown potential neuroprotective effects;however,the mechanisms underlying such a function remain unclear.AIM To investigate potential Tan-ⅡA neuroprotective effects in AD and to elucidate their underlying mechanisms.METHODS Hematoxylin and eosin staining was utilized to analyze structural brain tissue morphology.To assess changes in oxidative stress and neuroinflammation,we performed enzyme-linked immunosorbent assay and western blotting.Additionally,the effect of Tan-ⅡA on AD cell models was evaluated in vitro using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay.Genetic changes related to the long non-coding RNA(lncRNA)nuclear-enriched abundant transcript 1(NEAT1)/microRNA(miRNA,miR)-291a-3p/member RAS oncogene family Rab22a axis were assessed through reverse transcription quantitative polymerase chain reaction.RESULTS In vivo,Tan-ⅡA treatment improved neuronal morphology and attenuated oxidative stress and neuroinflammation in the brain tissue of AD mice.In vitro experiments showed that Tan-ⅡA dose-dependently ameliorated the amyloid-beta 1-42-induced reduction of neural stem cell viability,apoptosis,oxidative stress,and neuroinflammation.In this process,the lncRNA NEAT1-a potential therapeutic target-is highly expressed in AD mice and downregulated via Tan-ⅡA treatment.Mechanistically,NEAT1 promotes the transcription and translation of Rab22a via miR-291a-3p,which activates nuclear factor kappa-B(NF-κB)signaling,leading to activation of the pro-apoptotic B-cell lymphoma 2-associated X protein and inhibition of the anti-apoptotic B-cell lymphoma 2 protein,which exacerbates AD.Tan-ⅡA intervention effectively blocked this process by inhibiting the NEAT1/miR-291a-3p/Rab22a axis and NF-κB signaling.CONCLUSION This study demonstrates that Tan-ⅡA exerts neuroprotective effects in AD by modulating the NEAT1/miR-291a-3p/Rab22a/NF-κB signaling pathway,serving as a foundation for the development of innovative approaches for AD therapy.

The Impact of Nursing Staff’s Work Attitude on the Fear of Patients Recovering from Benign Tumors:Family Support as a Mediating Variable

The perception of nursing staff’s attitude influences patient fear.Understanding this dynamic is crucial for fostering a supportive environment conducive to patient well-being and effective healthcare practices.The purpose of this research is to investigate how the attitudes and behaviours of nursing staff influence the fear and anxiety levels of patients recovering from benign tumors,aiming to improve patient care and recovery outcomes.Data was collected from a sample of 100 participants,comprising 20 nursing staff and 80 patients recovering from benign tumors.Surveys were administered to gather quantitative data on attitudes and fear levels.Participants were selected randomly from hospital records and outpatient clinics.Our analysis encompassed nursing staff attitude,patient fear levels,the influence of family support,progression of tumor recovery,patient-reported satisfaction,and the quality of healthcare services provided.The quantitative aspect utilized PLS-SEM software to perform regression analysis,evaluating both direct and indirect effects.Statistical analysis assessed the relationships between nursing staff attitudes,patient fear during benign tumor recovery,and the mediating role of family support.The findings of the study demonstrate that better nurse attitudes(Hypothesis 1,β=0.45,p<0.001)and stronger family support(Hypothesis 2,β=0.32;p<0.001) are linked to lower levels of patient fear.Partially mediating the relationship between nurse attitudes and patient fear,according to Hypothesis 3(β=0.28,p<0.002),is family support.Patients’perceptions of family support are highly influenced by nursing behaviour,as demonstrated by Hypothesis 4(β=0.38;p<0.001).Our research showed a strong relationship between the attitudes of nursing personnel and patient fear levels.Family support demonstrated a strong mediating effect on patient fear.Patient-reported satisfaction is positively correlated with family support.However,no significant relationship was found between healthcare service quality and patient fear.

The Development of Community-Based Family Healthcare: A Cross-Sectional Study in Haidian, Beijing, China

The outbreak of Covid-19 affects China’s health delivery system, and the current status of primary health services after the Covid-19 pandemic is not yet clear. To further explore the current status of demands of family health services, we conducted a cross-sectional survey, in the community of Haidian District, Beijing. Chi-square test analysis and multivariate logistic regression models were used to identify factors influencing residents’ demands for family healthcare services. Results show that population of married (OR = 3.108), living with parents (OR = 2.171), degree of Junior high school and above (OR = 7.250) and high school (OR = 7.670), Annual income: 0 - 56,000 (OR = 3.680) and 72,001 - 88,000 (OR = 1.690) have significant demands for family health care. The approach to building primary health services in Haidian District is worth promoting, but it is also important to pay attention to the health inequalities that can occur when patients are moved down to the grassroots level. .

A family nurse-led intervention for reducing health services’utilization in individuals with chronic diseases:The ADVICE pilot study

Objectives:Intensive health services'utilization is common in older individuals affected by chronic diseases.This study assessed whether a structured family nurse-led educational intervention would be effective in reducing health services'use(readmissions and/or emergency service access)among older people affected by chronic conditions.Methods:This is a non-randomized before-after pilot study.A sample of 78 patients was recruited from two general practices in Italy and 70 among them were followed for 8 months.Standard home care was provided during the first four months'period(months 1-4),followed by the educational intervention until the end of the study(months 5-8).The intervention,based on the teach-back method,consisted of by-weekly 60-min home sessions targeting aspects of the disease and its treatment,potential complications,medication adherence,and health behaviours.Rates of health services'use were collected immediately before(T0),and after the interventions(T1).Differences in utilization rates were examined by the McNemar's test.Potential factors associated with the risk of health services'use were explored with a Cox proportional hazard regression model.Results:The sample(n=78)was predominantly female(n=50,64.1%),and had a mean age of 76.2(SD=4.8)years.Diabetes mellitus was the most frequent disease(n=27,34.6%).McNemar's test indicated a significant reduction in health services'use at T1(McNemar χ^(2)==28.03,P<0.001).Cox regressions indicated that time and patient education,as well as their interaction,were the only variables positively associated with the probability of health services'use.Conclusion:A teach-back intervention led by a family nurse practitioner has the potential to reduce health services'use in older patients with chronic diseases.

Clinical Utilization of Nursing Process in Improving Patient’s Outcome and Its Associated Factors: A Cross-Sectional Study among Nurses and Midwives Working at Njombe Regional Referral Hospital, Tanzania

Background: Improvement of patient care in any hospital depends primarily on the quality of nursing care. Nursing care is enhanced by the nursing process, which outlines the nursing activities to be provided for a patient. Methods and Materials: A cross sectional design employing quantitative methods was conducted in Njombe RRH in December 2021. Quantitative data were collected from nurses and midwives from all wards by simple random sampling techniques using a sample-size calculator. SPSS version 26.0 was used to analyse data whereby a p-value of 0.05 was considered a decision mark for the significance of the result;Chi-square and Logistic regression respectively were used to find out the association and its strength between variables. Result: Majority of the respondents, 41 (85.4%), had inadequate knowledge and 33 (68.8%) found them people with a negative attitude to the nursing process. Significantly, there is an association between knowledge and clinical utilization (AOR 2.24;95% CI: 1.6 - 2.5;P 0.04), attitude and clinical utilization (AOR 4.32;95% CI: 1.8 - 3.7;P Conclusion: A knowledge gap in relation to the utilization of the nursing process and a negative attitude were noted to be associated significantly with the utilization of the nursing process among nurses and midwives. It is recommended on-job training, supportive supervision, and Value Clarification and Attitude Transformation (VCAT) are the best interventions to address the knowledge gap and negative attitudes respectively.

A Family of Global Attractors for the Generalized Kirchhoff-Beam Equations

In this paper, we discuss the existence and uniqueness of global solutions, the existence of the family of global attractors and its dimension estimation for generalized Beam-Kirchhoff equation under initial conditions and boundary conditions, using the previous research results for reference. Firstly, the existence of bounded absorption set is proved by using a prior estimation, then the existence and uniqueness of the global solution of the problem is proved by using the classical Galerkin’s method. Finally, Housdorff dimension and fractal dimension of the family of global attractors are estimated by linear variational method and generalized Sobolev-Lieb-Thirring inequality.

Family and twin studies in inflammatory bowel disease

Studies examining the inheritance of inflammatory bowel disease （IBD） within different family groups have been the basis for recent molecular advances in the genetics of IBD. The derived heritability in Crohn＇s disease （CD） is higher than in many other complex diseases. The risk of IBD is highest in first-degree relatives of a CD proband, but first-degree relatives of a proband suffering from ulcerative colitis （UC） and more distant relatives are also at increased risk. Disease concordance rates in IBD have been examined in multiplex families and in three large European twin studies.

Structure and function of the contactin-associated protein family in myelinated axons and their relationship with nerve diseases

The contactin-associated protein （Caspr） family participates in nerve excitation and conduction, and neurotransmitter release in myelinated axons. We analyzed the structures and functions of the Caspr family- CNTNAP1 （Casprl）, CNTNAP2 （Caspr2）, CNTNAP3 （Caspr3）, CNTNAP4 （Caspr4） and CNTNAP5 （Caspr5）, Casprl-5 is not only involved in the formation of myelinated axons, but also participates in maintaining the stability of adjacent connections. Casprl participates in the formation, differentiation, and proliferation of neurons and astrocytes, and in motor control and cognitive function. We also analyzed the relationship between the Caspr family and neurodegenerative diseases, multiple sclerosis, and autoimmune encephalitis. However, the effects of Caspr on disease course and prognosis remain poorly understood. The effects of Caspr on disease diagnosis and treatment need further investigation.

Adenomas of the common bile duct in familial adenomatous polyposis

Familial adenomatous polyposis(FAP)or Gardner’s syndrome is often accompanied by adenomas of the stomach and duodenum.We experienced a case of adenomas of the common bile duct in a 40-year-old woman with FAP presenting with acute cholangitis.Only 8 cases of adenomas or adenocarcinoma ofthe common bile duct have been reported in the literature in patients with FAP or Gardner’s syndrome.Those patients presented with acute cholangitis or pancreatitis.Local excision or Whipple procedure may be the reasonable surgical option.

Effects of harvest intensity on the marketable organ yield,growth and reproduction of non-timber forest products(NTFPs):implication for conservation and sustainable utilization of NTFPs

Background:Non-timber forest products(NTFPs)are an important part of forest biodiversity,and the subsistence and trade of local people,especially in less developed countries.Because of the high ecological and economic value,NTFPs have faced the problem of over-exploitation,and the key to solve this problem is to determine the feasible way of sustainable utilization of NTFPs.Harvest intensity is one of the most important and easily controlled utilization factors,which can greatly influence the plant individual survival,growth and reproductive performances,and even the population structure and dynamics.Therefore,we chose two common and important NTFPs species with different marketable parts(i.e.,Acanthopanax senticosus with tender leaves and Aralia elata with tender buds)as our study objects.Aiming to determine the optimum harvest intensity for sustainably utilizing both NTFPs species,five levels of harvest intensity treatments(i.e.,control,light,medium,high and severe)were designed to assess the effects of harvest intensity on their marketable organ yield,plant growth and reproductive performances.Results:The biomass growth rates of marketable organ and plant growth of A.senticosus under light harvest intensity treatment were significantly higher than those under other harvest intensities.The plant height growth and 1000-seed weight of A.elata under severe harvest intensity treatment were significantly lower than those under control treatment.Conclusions:The light harvest intensity with 25% leaf removal and the high harvest intensity with all terminal buds harvested are the optimum harvest intensity to maintain the sustainable utilization of A.senticosus and A.elata,respectively.These findings could provide managers with basic but practical guidance for making decisions about the sustainable harvest management plan for the cultivated NTFPs species,and further provide a theoretical basis for managers to establish the harvest regulations for wild NTFPs species.Consequently,the local residents or communities can improve their income while ensure the sustainable development of wild NTFPs.

Family history and disease outcomes in patients with Crohn's disease:A comparison between China and the United States

AIM To investigate the differences in family history of inflammatory bowel disease(IBD) and clinical outcomes among individuals with Crohn's disease(CD) residing in China and the United States.METHODS We performed a survey-based cross-sectional study of participants with CD recruited from China and the United States.We compared the prevalence of IBD family history and history of ileal involvement,CD-related surgeries and IBD medications in China and the United States,adjusting for potential confounders.RESULTS We recruited 49 participants from China and 145 from the United States.The prevalence of family history of IBD was significantly lower in China compared with the United States(China:4.1%,United States:39.3%).The three most commonly affected types of relatives were cousin,sibling,and parent in the United States compared with child and sibling in China.Ileal involvement(China:63.3%,United States:63.5%) and surgery for CD(China:51.0%,United States:49.7%) were nearly equivalent in the two countries.CONCLUSION The lower prevalence of familial clustering of IBD in China may suggest that the etiology of CD is less attributed to genetic background or a family-shared environment compared with the United States.Despite the potential difference in etiology,surgery and ileal involvement were similar in the two countries.Examining the changes in family history during the continuing rise in IBD may provide further insight into the etiology of CD.
