Objective To present an assessment method based on oscillometric upper-arm cuff pressure wave for realizing home-based detection of arteriosclerosis.Methods An upper-arm cuff pressure wave acquisition device based on an electronic blood pressure monitor was designed to implement data collection for cuff inflation and deflation,as well as the 15 s pressure holding phase.Following preprocessing of the data collected during this holding phase,individual pulse waves were extracted for pulse decomposition analysis(PDA).A novel model that superimposed a logarithmic normal function with two Gaussian functions,and an optimization method that combined template matching and particle swarm optimization were proposed to efficiently and accurately extract PDA features.Gaussian process regression was employed for multifeature fusion analysis,leading to the proposal of a new predictive indicator for arteriosclerosis.Results The mean absolute error of PDA was less than 1.2%,and the average processing time for a single pulse wave was less than 0.2 s.The regression determination coefficient R2 between the obtained indicators and baPWV was 0.8178.Conclusion The analysis on upper-arm cuff pressure wave provides a new reference for non-invasive arteriosclerosis detection,and it can be applied to electronic blood pressure monitors for home-based monitoring,offering significant practical value.

This study aims to establish an efficient protoplast-mediated genetic transformation sys-tem for Pochonia chlamydosporia(P.chlamydosporia)to facilitate gene transformation,genetic modification,and subsequent biological function research.Through orthogonal testing,the study systematically optimized key factors influencing electroporation,including voltage,osmotic stabi-lizer,pulse time,nucleic acid concentration,and protoplast concentration.The results showed that the optimal electroporation conditions were:voltage of 250 V,osmotic stabilizer as 0.6 mol/L su-crose solution,pulse time of 10 ms,plasmid concentration of 1％,and protoplast concentration of 1×107 protoplasts/mL,yielding a transformation efficiency of 0.4 × 103 CFU/pg.The interaction analysis revealed that the five factors affected transformation efficiency in the following order:plasmid concentration＞protoplast concentration＞pulse time＞osmotic stabilizer type＞voltage.Based on the positive transformants,the study further evaluated their colony morphology,growth rate,conidial yield,mycelial dry weight,and the ability to infect the eggs of three types of animal gastrointestinal nematodes.The results indicated that the electroporation process did not signifi-cantly affect the biological functions of P.chlamydosporia.The transformants successfully ex-pressed enhanced green fluorescent protein(EGFP),and PCR analysis confirmed the successful in-tegration of the thiostrepton resistance gene.In conclusion,this study successfully established a protoplast-based electroporation-mediated genetic transformation system for P.chlamydosporia,providing a valuable foundation for further research into the mechanism of egg parasitism and the underlying genes involved in its biocontrol activity.

The pathogenesis and progression of depression are closely associated with functional dysregula-tion in the brain's reward and emotion-modulating circuits.As the central hub of the reward system,the nucleus accumbens(NAc)forms aberrant neural circuits with multiple brain regions-including the ventral tegmental area(VTA),medial prefrontal cortex(mPFC),amygdala(AMY),hippocampus(HIP),and paraventricular nucleus of the thalamus(PVT)-which have been empirically linked to depressive symptomatology.Acupuncture,with its multi-target therapeutic profile,aligns well with the multifactorial and multisystem dysregulation characteristic of depressive disorders.This review systematically examines the functional alterations of the NAc-centered neural circuitry in depression and explores the potential mechanisms of acupuncture intervention.Evidence suggests that acupuncture holistically ameliorates depression by:modulating dopaminergic transmission in the VTA-NAc pathway,enhancing neurotransmitter equilibrium in the mPFC-NAc circuit,bidirectionally regulating emotional stability via the AMY-NAc loop,attenuating HIP-NAc glutamatergic hyperactivity,and optimizing excitatory signaling in the thalamus-NAc circuit.Furthermore,this synthesis emphasizes a systems-level integration of circuit mechanisms,highlighting both the clinical applicability of acupuncture in depression treatment and recent advances in mechanistic research.The findings provide robust theoretical foundations and practical guidance for clinical practice,bridging translational neuroscience with therapeutic innovation.

The patient was hospitalized for treatment due to ovarian cancer 22 months post-surgery and recurrence for 3 months.During chemotherapy,carboplatin was administered intravenously following pretreatment with dexamethasone and diphenhydramine to mitigate potential adverse reactions.Thirteen minutes after the administration of carboplatin,the patient developed an acute allergic reaction manifesting as chest tightness and skin itching,followed by a significant increase in heart rate and blood pressure,a decrease in blood oxygen saturation,laryngeal edema,and respiratory distress.In response to this emergency,the administration of carboplatin was immediately halted,fluid was extracted from the PICC line,and epinephrine,dexamethasone,and diphenhydramine were given for treatment.Additional supportive measures included oxygen therapy and fluid resuscitation.Following these interventions,the patient's condition stabilized,with blood oxygen saturation,heart rate and blood pressure returning to normal levels.

With the rapid advancements in minimally invasive spine surgery and the increasingly sophisti-cated concept of visualization,transforaminal endoscopic lumbar discectomy(TELD)has become a primary treatment for lumbar disc herniation.Among the critical preoperative steps in TELD,foraminalplasty plays a pivotal role,as its quality directly impacts surgical outcomes and postoperative recurrence rates.This article systemati-cally reviews the evolution of foraminalplasty techniques,evaluates the selection and application of plasty sites,examines factors influencing stability after lumbar foraminalplasty,and highlights recent advancements in computer-assisted navigation.The goal is to serve as a comprehensive reference for clinicians.
