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. 展开更多

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. 展开更多

AIM:To investigate differences of clinical characteristics and disease courses between familial and sporadic inflammatory bowel disease(IBD)patients.METHODS:We obtained clinical data on Crohn’s disease(CD)(n=691)and ulcerative colitis(n=1113)from a tertiary referral medical center between 2005and 2012.Seventeen patients(2.5%)with CD and27 patients(2.4%)with ulcerative colitis(UC)were identified as having a familial history of IBD,including the first and second degree relatives.For each control case,three times the number of age-,sex-,and diagnosis year-matched CD and UC patients,without a family history of IBD,were randomly selected in this case control study.RESULTS:There were no significant differences in age or main symptom at diagnosis,extraintestinal manifestation,location/extent,behavior of disease activity,number of hospitalizations,number of operations,operation type,number of relapses,or oral medical treatment between familial and sporadic CD and UC patients.Median(min-max)follow-up periods after diagnosis of familial CD and sporadic CD patients were 84(24-312)and 36(8-240)mo,respectively(P=0.008).Familial CD patients more frequently used anti-tumor necrosis factor(TNF)antibodies compared to sporadic CD patients(17.6%vs 0%,P=0.014).CONCLUSION:In conclusion,a family history of IBD does not seem to be an important predictive factor affecting clinical characteristics or disease course even if there is a more frequent use of anti-TNF antibodies in familial CD patients compared to sporadic CD patients. 展开更多

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. 展开更多

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. 展开更多

The initial boundary value problem for a class of high-order Beam equations with quasilinear and strongly damped terms is studied. Firstly, the existence and uniqueness of the global solution of the equation are proved by prior estimation and Galerkin finite element method. Then the bounded absorption set is obtained by prior estimation, and the family of global attractors for the high-order Kirchhoff-Beam equation is obtained. The Frechet differentiability of the solution semigroup is proved after the linearization of the equation, and the decay of the volume element of the linearization problem is further proved. Finally, the Hausdorff dimension and Fractal dimension of the family of global attractors are proved to be finite. 展开更多

Coexistence of Crohn's disease(CD) and familial Mediterranean fever(FMF) is a rare condition and knowledge about this clinical situation is limited with a few case reports in the literature. The treatment of both diseases depends on their individual therapies. However, it is very hard to deal with this coexistence when CD is refractory to standard therapies. Ongoing activity of CD triggers the clinical attacks of FMF and the symptoms like abdominal pain interfere with both disease presentations which can cause problems about diagnostic and therapeutic approach. The main therapeutic agent for FMF is colchicine and diarrhea is the most common side effect of this drug. This side effect also causes problems about management of these diseases when both of them are clinically active. Here we report probably the first case in the literature with coexisting CD and FMF who was successfully treated by leukopheresis since he was refractory to conventional therapies for CD. 展开更多

Yin Yang 1(YY1) is a multi-functional transcription factor that regulates gene expression in a range of cell types,including neurons.It controls neuronal differentiation,as well as neuronal specification and migration during the development of the mammalian nervous system.Besides,YY1 also mediates the transcription of genes that are required for neuronal survival.An impairment of the transcriptional function of YY1 causes neuronal death.This review summarizes recent research findings that unveil the dysfunction of YY1 in multiple neurodegenerative disorders.The expression of disease proteins perturbs the function of YY1 via distinct molecular mechanisms,including recruitment to protein aggregates,protein degradation and aberrant nuclear/cytoplasmic shuttling.Understanding the pathogenic roles of YY1 will further broaden our knowledge of the disease mechanisms in distinct neurodegenerative disorders. 展开更多

Studies have shown that PARK1 gene is associated with the autosomal dominant inheritance of Parkinson's disease. PARK1 gene contains two mutation sites, namely Ala30Pro and Ala53Thr, which are located on exons 3 and 4, respectively. However, the genetic loci of the pathogenic genes remain unclear. In this study, blood samples were collected from 11 members of a family with high prevalence of Parkinson's disease, including four affected cases, five suspected cases and two non-affected cases. Point mutation screening of common mutation sites on PARK1 gene exon 4 was conducted using PCR, to determine the genetic loci of the causative gene for Parkinson's disease. Gene identification and sequencing results showed that a T base deletion mutation was observed in the PARK1 gene exon 4 of all 11 collected samples. It was confirmed that the PARK1 gene exon 4 gene mutation is an important pathogenic mutation for Parkinson's disease. 展开更多

Pressure is an effective and clean way to modify the electronic structures of materials,cause structural phase transitions and even induce the emergence of superconductivity.Here,we predicted several new phases of the Zr XY family at high pressures using the crystal structures search method together with first-principle calculations.In particular,the Zr Ge S compound undergoes an isosymmetric phase transition from P4/nmm-I to P4/nmm-II at approximately 82 GPa.Electronic band structures show that all the high-pressure phases are metallic.Among these new structures,P4/nmm-II Zr Ge S and P4/mmm Zr Ge Se can be quenched to ambient pressure with superconducting critical temperatures of approximately 8.1 K and 8.0 K,respectively.Our study provides a way to tune the structure,electronic properties,and superconducting behavior of topological materials through pressure. 展开更多

Understanding choice of family planning provider is fundamental for policy makers and program managers as they seek ways to both improve the coverage and increase the sustainability and efficiency of family planning services for Egypt to achieve its population objectives. This study focuses first on providing a descriptive profile of the patterns of reliance on sources of family planning services during the early 2000s. Binomial logit models are then estimated to obtain a more in depth understanding of the determinants of the choice of family planning providers in Egypt using the 2000 Egypt Demographic and Health Survey. The study offers insights into a number of aspects of family planning service provision about which there has been less previous investigation. There are marked differences in the extent to which Egyptian women rely on public or private providers for family planning services depending on the type of method they are seeking. Among the more important findings is the consistency women display in the choice of provider among women reporting multiple segments of use. With regard to the determinants of the choice of provider for family planning services, perhaps the most interesting finding is that household wealth was not a significant determinant of the choice of provider. This may reflect that private sources met the demand for family planning services of significant proportions of women in rural areas and among those in the low income groups. 展开更多

From the perspectives of the prosperity of the Sui and Tang dynasties,the rise and fall of the aristocrats and the prevalence of the imperial examination,this paper studies the impact of family precepts,rules,and ethics on children’s education.I believe that an important feature of family precepts in the Tang Dynasty was the development of the cultural tradition of poetry and literature study within the family,which promoted virtues like loyalty,filial piety,diligence,frugality and modesty and had a profound influence on future generations.The rise and fall of Tang Dynasty families was closely related to family precepts,rules,ethics,and learning.Famous and respectable families often regarded these traits as important means to maintain the family’s status,which objectively promoted the development of family scholarship and the importance of children’s education in the Tang Dynasty.The concept of learning as a“carry-on treasure”has become a common belief among scholars and has played a positive role in educating Chinese society,enriching our culture,and keeping society in order. 展开更多

For a given triangulation Δ of a region R of interest, let S_8~2(Δ): = {s∈C^2(R): s|_1∈P_8,l∈Δ} be the space of all splines of degree 8 and smoothness 2, where t denotes any triangle of Δ and P_8 the space of polynomials of total degree≤8. Furthermore, let S_8~2(Δ):={s∈S_8~3(Δ):s∈C^3 at v, v∈Δ} be a super spline subspace of S_8~2(Δ). We construel a collection of locally supported splines in S_8~2(Δ) which can be used to achieve lhe full approximation order of S_8~2(Δ) and its cardinalily is less than the di- mension of super spline space space S_8~2(Δ). 展开更多
