Obstructive sleep apnea (OSA) is an increasingly widespread sleep-breathing disordered disease, and is an independent risk factor for many high-risk chronic diseases such as hypertension, coronary heart disease, stroke, arrhythmias and diabetes, which is potentially fatal. The key to the prevention and treatment of OSA is early diagnosis and treatment, so the assessment and diagnostic technologies of OSA have become a research hotspot. This paper reviews the research progresses of severity assessment parameters and diagnostic technologies of OSA, and discusses their future development trends. In terms of severity assessment parameters of OSA, apnea hypopnea index (AHI), as the gold standard, together with the percentage of duration of apnea hypopnea (AH%), lowest oxygen saturation (LSpO₂), heart rate variability (HRV), oxygen desaturation index (ODI) and the emerging biomarkers, constitute a multi-dimensional evaluation system. Specifically, the AHI, which measures the frequency of sleep respiratory events per hour, does not fully reflect the patients’ overall sleep quality or the extent of their daytime functional impairments. To address this limitation, the AH%, which measures the proportion of the entire sleep cycle affected by apneas and hypopneas, deepens our understanding of the impact on sleep quality. The LSpO₂ plays a critical role in highlighting the potential severe hypoxic episodes during sleep, while the HRV offers a different perspective by analyzing the fluctuations in heart rate thereby revealing the activity of the autonomic nervous system. The ODI provides a direct and objective measure of patients’ nocturnal oxygenation stability by calculating the number of desaturation events per hour, and the biomarkers offers novel insights into the diagnosis and management of OSA, and fosters the development of more precise and tailored OSA therapeutic strategies. In terms of diagnostic techniques of OSA, the standardized questionnaire and Epworth sleepiness scale (ESS) is a simple and effective method for preliminary screening of OSA, and the polysomnography (PSG) which is based on recording multiple physiological signals stands for gold standard, but it has limitations of complex operations, high costs and inconvenience. As a convenient alternative, the home sleep apnea testing (HSAT) allows patients to monitor their sleep with simplified equipment in the comfort of their own homes, and the cardiopulmonary coupling (CPC) offers a minimal version that simply analyzes the electrocardiogram (ECG) signals. As an emerging diagnostic technology of OSA, machine learning (ML) and artificial intelligence (AI) adeptly pinpoint respiratory incidents and expose delicate physiological changes, thus casting new light on the diagnostic approach to OSA. In addition, imaging examination utilizes detailed visual representations of the airway’s structure and assists in recognizing structural abnormalities that may result in obstructed airways, while sound monitoring technology records and analyzes snoring and breathing sounds to detect the condition subtly, and thus further expands our medical diagnostic toolkit. As for the future development directions, it can be predicted that interdisciplinary integrated researches, the construction of personalized diagnosis and treatment models, and the popularization of high-tech in clinical applications will become the development trends in the field of OSA evaluation and diagnosis.

Isosteviol is a tetracyclic diterpenoid compound obtained by hydrolysis of natural stevia glycoside under acidic conditions. It has many pharmacological activities, such as anti-tumor, hypoglycemic, anti-inflammatory and antibacterial. Due to its low water solubility, low activity and low bioavailability, isosteviol has poor performance. In order to overcome these shortcomings, scholars have obtained a large number of isosteviol derivatives with novel structures and excellent activity. In this paper, we review the recent progress in the research on the structure modification, biological activity, structure-activity relationship and microbial transformation of isosteviol, in order to provide a reference for the development of new drugs of isosteviol and its derivatives.

Cardiovascular disease (CVD), chronic kidney disease (CKD), and metabolic disorders are the 3 major chronic diseases threatening human health, which are closely related and often coexist, significantly increasing the difficulty of disease management. In response, the American Heart Association (AHA) proposed a novel disease concept of “cardiovascular-kidney-metabolic (CKM) syndrome” in October 2023, which has triggered widespread concern about the co-treatment of heart and kidney diseases and the prevention and treatment of metabolic disorders around the world. This review posits that effectively managing CKM syndrome requires a new and multidimensional paradigm for diagnosis and risk prediction that integrates biological insights, advanced technology and social determinants of health (SDoH). We argue that the core pathological driver is a “metabolic toxic environment”, fueled by adipose tissue dysfunction and characterized by a vicious cycle of systemic inflammation and oxidative stress, which forms a common pathway to multi-organ injury. The at-risk population is defined not only by biological characteristics but also significantly impacted by adverse SDoH, which can elevate the risk of advanced CKM by a factor of 1.18 to 3.50, underscoring the critical need for equity in screening and care strategies. This review systematically charts the progression of diagnostic technologies. In diagnostics, we highlight a crucial shift from single-marker assessments to comprehensive multi-marker panels. The synergistic application of traditional biomarkers like NT-proBNP (reflecting cardiac stress) and UACR (indicating kidney damage) with emerging indicators such as systemic immune-inflammation index (SII) and Klotho protein facilitates a holistic evaluation of multi-organ health. Furthermore, this paper explores the pivotal role of non-invasive monitoring technologies in detecting subclinical disease. Techniques like multi-wavelength photoplethysmography (PPG) and impedance cardiography (ICG) provide a real-time window into microcirculatory and hemodynamic status, enabling the identification of early, often asymptomatic, functional abnormalities that precede overt organ failure. In imaging, progress is marked by a move towards precise, quantitative evaluation, exemplified by artificial intelligence-powered quantitative computed tomography (AI-QCT). By integrating AI-QCT with clinical risk factors, the predictive accuracy for cardiovascular events within 6 months significantly improves, with the area under the curve (AUC) increasing from 0.637 to 0.688, demonstrating its potential for reclassifying risk in CKM stage 3. In the domain of risk prediction, we trace the evolution from traditional statistical tools to next-generation models. The new PREVENT equation represents a major advancement by incorporating key kidney function markers (eGFR, UACR), which can enhance the detection rate of CKD in primary care by 20%-30%. However, we contend that the future lies in dynamic, machine learning-based models. Algorithms such as XGBoost have achieved an AUC of 0.82 for predicting 365-day cardiovascular events, while deep learning models like KFDeep have demonstrated exceptional performance in predicting kidney failure risk with an AUC of 0.946. Unlike static calculators, these AI-driven tools can process complex, multimodal data and continuously update risk profiles, paving the way for truly personalized and proactive medicine. In conclusion, this review advocates for a paradigm shift toward a holistic and technologically advanced framework for CKM management. Future efforts must focus on the deep integration of multimodal data, the development of novel AI-driven biomarkers, the implementation of refined SDoH-informed interventions, and the promotion of interdisciplinary collaboration to construct an efficient, equitable, and effective system for CKM screening and intervention.

Aim To screen and study the effects of Tao Hong Si Wu decoction(THSWD)-mediated treat-ment on circular RNA(circRNA)expression profiles in rats with middle cerebral artery occlusion(MCAO),and investigate the possible roles and molecular mecha-nisms of THSWD.Methods Next-generation RNA sequencing was conducted to identify circRNA expres-sion profiles in MCAO rats after treatment with THSWD and compared with the MCAO model group and control group.Bioinformatics analysis was performed to predict the potential target microRNAs and mRNAs.Gene On-tology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analyses for the potential target mRNAs were applied to explore the potential roles of differentially expressed circRNAs.RT-qPCR was performed to verify circRNAs with significant differences in expression.Results We identified 87 significantly differentially expressed circRNAs between the MCAO group versus the control group,and 86 sig-nificantly differentially expressed circRNAs between the MCAO group versus the THSWD group.respective-ly.Among them,17 circRNAs induced by the MCAO model were reversed via treatment with THSWD.To demonstrate the roles of mRNAs targeted by DECs,the GO and KEGG databases were used.Further analysis revealed that five circRNAs may play important roles in the development of MCAO.Conclusions The com-prehensive expression profile of circRNAs in rats with middle cerebral artery occlusion after THSWD treat-ment is determined for the first time,suggesting that the therapeutic effect of THSWD on MCAO may be a-chieved by regulating the expression of circRNAs.

Objective To evaluate the safety and effectiveness of laparoscopic radical resection of colorectal cancer without indwelling gastric tube during the perioperative period for postoperative rehabilitation of patients.Methods A total of 90 patients who underwent laparoscopic radical resection for colorectal cancer in our hospital from January 2021 to January 2023 were selected as the study objects,they were randomly divided into the observation group and the control group,with 45 cases in each group.The time of first postoperative exhaust and defecation,postoperative hospital stay,and the occurrence of complications such as throat pain,nausea and vomiting,pulmonary infection,intestinal obstruction,and anastomotic fistula of patients were compared between the two groups.Results The time of first postoperative exhaust and defecation and postoperative hospital stay of patients in the observation group were shorter than those in the control group,with statistically significant differences(P<0.05).The incidence of throat pain and nausea and vomiting of patients in the observation group was lower than that in the control group,with statistically significant difference(P<0.05);However,there was no statistically significant difference in postoperative complications such as pulmonary infection,intestinal obstruction,and anastomotic fistula of patients between the two groups(P>0.05).Conclusion Laparoscopic radical resection of colorectal cancer without indwelling gastric tube during the perioperative period will not increase the incidence of postoperative complications such as pulmonary infection,intestinal obstruction,and anastomotic fistula,instead,it can reduce the incidence of postoperative throat pain and nausea and vomiting,shorten hospital stay,and accelerate postoperative recovery of patients.

Objective:To investigate the expression of NOD-like receptor protein 3(NLRP3)inflammasome and its relation-ship with granulosa cell apoptosis in patients with polycystic ovary syndrome(PCOS).Methods:Follicular fluid and ovarian granulosa cells were collected from 17 PCOS patients(PCOS group)and 20 non-PCOS patients(control group),and the expression levels of pro-inflammatory factor,TNF-α,IL-1β and IL-18 in follicular fluid were detected by ELISA.RT-PCR and Western blot were used to de-tect NLRP3 mRNA and NLRP3 inflammasome associated protein NLRP3,ASC and cleaved caspase-1 and autophagy related protein LC3-Ⅱ/LC3-Ⅰ and p62 expression level in granulosa cells.TUNEL assay was used to detect the apoptotic level of granulosa cells in both groups.NLRP3 silenced siRNA(si-NLRP3)and negative control sequence(si-NC)were transfected into human ovarian cancer granulosa cell line KGN cells by siRNA interference technique in vitro.TNF-α was used to simulate PCOS-related cell damage.KGN cells were divided into 4 groups according to different treatment methods:Ctrl group,TNF-α group,TNF-α+si-NLRP3 group and TNF-α+si-NC group.The levels of DHEA,testosterone,IL-1β and IL-18 in supernatant were detected by ELISA.TUNEL assay was used to detect the apoptosis level of KGN cells.The LC3-Ⅱ/LC3-Ⅰ and p62,NLRP3,ASC and cleaved caspase-1 protein expression levels,and NF-κB p-p65 level(NF-κB p-p65/NF-κB p65)in KGN cells were detected by Western blot.Results:Compared with con-trol group,the concentration of TNF-α,IL-1β,and IL-18 in follicular fluid of PCOS patients,and LC3-Ⅱ/LC3-Ⅰ,NLRP3 mRNA and the protein expression of NLRP3,ASC,and cleaved caspase-1 in granulosa cells of and apoptosis were significantly increased(P<0.05 or P<0.01),while the protein expression of p62 was significantly decreased(P<0.01).Compared with Ctrl group,the levels of DHEA,testosterone,IL-1β and IL-18 in supernatant of TNF-α group,TNF-α+si-NC group,and TNF-α+si-NLRP3 group,and LC3-Ⅱ/LC3-Ⅰ,ASC and cleaved caspase-1 protein expression,and the level of NF-κB p-p65 and apoptosis were significantly increased(P<0.05 or P<0.01),while p62 protein was significantly decreased(P<0.01).NLRP3 was significantly decreased except in TNF-α+si-NLRP3 group(P<0.01),while in the TNF-α group and TNF-α+si-NC group was significantly increased(P<0.01).However,com-pared with TNF-α group,the above indexes in TNF-α+si-NLRP3 group were significantly decreased(P<0.05),and TNF-α+si-NC group had no significant change(P>0.05).Conclusion:The over-activated NLRP3 inflammasome in granulosa cells may promote cell inflammatory injury and autophagy apoptosis in PCOS patients through NF-κB pathway.

Objective:To explore the different characteristics of early postoperative kinesiophobia in elderly patients with total hip arthroplasty (THA) and analyze the influencing factors, so as to provide reference for formulating targeted nursing strategies.Methods:This study was a cross-sectional study. Using the convenient sampling method, a total of 225 elderly THA patients admitted to the Second Affiliated Hospital of Air Force Medical University of PLA from May 2022 to June 2023 were selected as the research objects. The evaluation was conducted using the general information questionnaire, Tampa Scale for Kinesiophobia (TSK), Numeric Rating Scale, Pain Catastrophizing Scale and Groningen Orthopedic Social Support Scale.Results:A total of 225 questionnaires were distributed and 210 valid questionnaires were collected, with an effective response rate of 93.33%. The TSK score of 210 elderly THA patients was (38.76±8.52), among which 49.52% (104/210) of patients had kinesiophobia (TSK>37 points). The latent profile analysis results showed that early postoperative kinesiophobia in elderly THA patients could be divided into three potential categories, such as catastrophic cognition-high kinesiophobia group (48.57%, 102/210), uncertain cognition-moderate kinesiophobia group (20.48%, 43/210) and positive cognition-low kinesiophobia group (30.95%, 65/210). The results of Logistic regression analysis showed that age greater than or equal to 76 years old, education level of primary school or below, high comorbidity, moderate to severe pain and positive catastrophic pain were the influencing factors for patients in the catastrophic cognition-high kinesiophobia group ( P<0.05), while education level of primary school or below and low social support were the influencing factors for patients in the uncertain cognition-moderate kinesiophobia group ( P<0.05) . Conclusions:There is significant heterogeneity in early postoperative kinesiophobia among elderly patients with total hip arthroplasty, with the main influencing factors being advanced age, physical pain, social support and educational level. It is suggested that medical staff should carry out psychological counseling according to the characteristics of early kinesiophobia of different categories of patients, strengthen social support to correct wrong cognition of patients, reduce their kinesiophobia and improve early rehabilitation training behavior.

Perilla frutescens,a short-day plant,is rich in biologically active substances and nutrients.Current research on Perilla frutescens focuses on agronomic traits such as yield and fatty acid accumula-tion,with limited exploration of the flowering process and floral organ development.The molecular regu-latory mechanisms underlying these aspects remain unclear.FLOWERING LOUC T(FT)is a florigen in Arabidopsis,plays critical roles in floral transition.PfFT3 is unannotated by genome but annotated by transcriptomics data to the FT-like subfamily.Its function in controlling flowering is yet to be explored.Here subcellular localization analysis showed that PfFT3 is localized in the nucleus and cytoplasm.The plant over-expression vector pCAMBIAI1303-PfFT3 was constructed and transformed into wild-type(Col-0)and mutant fd-2,fd-3,and ft-10 plants by agrobacterium-mediated inflorescence infiltration as a means of obtaining genetically stable and pure overexpression and backfill transgenic lines in Arabidopsis,respectively.Analysis of the results showed that overexpression of PfFT3 significantly promoted early flowering in Arabidopsis and rescued the late-flowering phenotype of the mutants fd-2,fd-3,and ft-10,and that expression of the exogenous PfFT3 promoted the expression of the downstream endogenous flow-ering genes AtSOC1,AtAP1,AtFUL,and AtLFY.This study demonstrates the positive role of PfFT3 in promoting flowering,providing a foundation for further investigation of PfPEBP function and advancing the breeding of early-flowering Perilla frrutescens cultivars.
