Objective: To explore the association between types of obesity and 10-year risk of atherosclerotic cardiovascular disease (ASCVD) among hypertensive patients, so as to provide the basis for formulating ASCVD prevention strategies for hypertensive patients. Methods: From January to December 2021, hypertensive patients who were under follow-up management and completed health examinations at three community health service centers in Linping District, Hangzhou City were selected by a cluster sampling method. Basic information, lifestyle, disease history, height, weight, waist circumference (WC), and blood biochemical indicators were collected through health examination data. Based on assessments of body mass index (BMI) and WC, participants were categorized into four types: non-obese, general obesity only, central obesity only, and combined obesity. The Prediction for ASCVD risk in China (China-PAR) was used to assess 10-year ASCVD risk, which was categorized as low, moderate, and high risk. Multivariable logistic regression models were used to analyze the association between different types of obesity and ASCVD risk among hypertensive patients. Results: A total of 10 408 hypertensive patients were included, with a median age of 68.00 (interquartile range, 10.00) years. There were 4 301 (41.32%) males and 6 107 (58.68%) females. The proportions of non-obese, general obesity only, central obesity only, and combined obesity were 34.93% (3 635 individuals), 22.85% (2 378 individuals), 4.32% (450 individuals), and 37.90% (3 945 individuals), respectively. There were 3 389 (33.52%) cases at high risk of ASCVD. Among them, high ASCVD risk was observed in 1 107 (30.45%), 896 (37.68%), 122 (27.11%), and 1 364 (34.58%) patients with non-obese, general obesity only, central obesity only, and combined obesity, respectively. Multivariable logistic regression analysis showed that after adjusting for gender, age, smoking, drinking, physical activity, and diabetes, the risk of high ASCVD in hypertensive patients with general obesity only and combined obesity was 1.383 times (95%CI: 1.235-1.548) and 1.225 times (95%CI: 1.109-1.354) that of non-obese hypertensive patients, respectively. Conclusions General obesity only and combined obesity can increase the 10-year high risk of ASCVD among hypertensive patients. It is necessary to strengthen comprehensive management of body weight and WC among hypertensive patients to reduce the risk of ASCVD.

Objective To explore the effect of remote ischemic preconditioning (RIPC) on preoperative heart rate variability in patients with heart valves. Methods Patients scheduled to undergo on-pump cardiac valve surgery in the Department of Cardiovascular Surgery, General Hospital of Northern Theater Command, between January and July 2022 were initially enrolled. Eligible patients were randomly assigned at a 1 : 1 ratio to either the RIPC group or the control group. Relevant indicators of heart rate variability [standard deviation of NN interval (SDNN), standard deviation of mean value of NN interval in every five minutes (SDANN), mean square root of difference between consecutive NN intervals (RMSSD), percentage of adjacent RR interval>50 ms (PNN50), low frequency (LF) component, high frequency (HF) component and LF/HF] at 8 hours in the morning on the surgical day between two groups were compared. Results A total of 118 patients were initially assessed. After screening, 58 patients were excluded, and 60 patients provided written informed consent and were enrolled in the trial, with 30 allocated to the RIPC group and 30 to the control group. Seven patients in the control group and 5 patients in the RIPC group were subsequently excluded due to missing heart rate variability data resulting from cancelled operations. Finally, 23 patients in the control group and 25 patients in the RIPC group were included in the analysis. There was no statistical difference in baseline characteristics between the two groups, and there was no significant difference in heart rate variability 24 hours before intervention (P>0.05). After the intervention measures were taken, the comparison of the results of heart rate variability at 8 hours on the day of operation showed that SDNN and SDANN of patients in the RIPC group were higher than those in the control group, with statistical differences (P<0.05). Conclusion RIPC can stabilize the preoperative heart rate variability of patients undergoing cardiac valve surgery.

BACKGROUND:In vitro construction of tissue-engineered intestinal models plays an important role in intestinal regeneration and intestinal disease research.The interaction of intestinal nervous system and intestinal epithelial barrier to maintain body homeostasis is a hot topic in the bionic construction of tissue-engineered intestinal tract.OBJECTIVE:To construct a bionic model that can mimic the enteric nervous system in vivo.METHODS:Using fibroin protein with villus structure as scaffold,human induced neural stem cells solidified with collagen were added to intestinal epithelial cells(Caco-2 and HT29-MTX-E12)for 3-day culture to construct a co-culture system of intestinal epithelial cells and nerve cells(co-culture group).Human induced neural stem cells or intestinal epithelial cells cultured alone that were inoculated with fibroin scaffolds were set as controls.Cell morphology was observed by scanning electron microscopy and hematoxylin-eosin staining.Cell activity was detected by Live/Dead cell staining.Human induced neural stem cell differentiation was detected by β-microtubulin immunofluorescence staining.Intestinal epithelial histological properties and barrier function were detected by microvillin,sucrase-isomaltase,tight junction protein 1,E-calmodulin,and mucin-2 immunofluorescence staining.The function of mucus secretion from intestinal epithelial cells was detected by Alcian blue staining.Alkaline phosphatase staining was performed to detect differentiation of intestinal epithelial cells,at the same time,sucrase-isomaltase,tight junction protein 1,and alkaline phosphatase mRNAs were detected by RT-qRCR.RESULTS AND CONCLUSION:The neuralized intestinal mucosal co-culture model with villi structure was successfully constructed,and neural stem cells and intestinal epithelial cells on the fibroin scaffold showed good cellular activities.After neuralization,the activity of alkaline phosphatase and sucrase-isomaltase in intestinal epithelial cells was enhanced,while the expression level of tight junction protein 1 was up-regulated.To conclude,the neuralized bionic intestinal epithelial model is beneficial to the maturation of intestinal mucosal epithelial cells and the formation of barrier function.

Based on the typical cases from Case Records as a Guide to Clinical Practice （《临证指南医案》） where YE Tianshi applied the "morning and evening differential treatment"， the main types are summarized as follows. When there is middle-lower interlocking injury， and yin deficiency with wind stirring， the method of restraining and consolidating in the morning can be used to restrict jueyang （厥阳）. For deficiency of the extraordinary vessels and heart-spleen ying （营） impairment， the method of consolidating should be used to raise yang in the morning， while the method of moistening and nourishing ying-yin in the evening is used. For lower jiao （焦） depletion with phlegm turbidity obstructing the orifices， it is recommended to tonify lower jiao in the morning and fortify spleen and dissolve phlegm in the evening. If there is kidney-yin depletion with dampness obstructing the qi， it is suggested to supplement kidney and improve qi reception in the morning， while purify upper jiao in the evening. For deficiency and impairment of the collateral vessels， the method of moistening and nourishing ying-yin in the evening can be used. For heart-spleen qi knot， it is recommended to dissolve phlegm and dispel stasis in the evening. In clinical practice， the same medicinal formula can be used with different methods which change according to the syndrome. Taking Sishen Pills （四神丸） and Yuhu Elixir （玉壶丹） as examples， employing different methods in accordance with the primary and secondary pathomechanisms can help transform complex， multiple pathomechanisms into organized treatment steps， providing ideas for managing complicated syndromes with modern Chinese medicine in clinical practice.

Background: and Purpose In patients with large vessel occlusion (LVO), intravenous thrombolysis (IVT) frequently alters thrombus location; however, the clinical impact of this phenomenon remains unclear. We aimed to compare post-IVT thrombus dynamics between tenecteplase and alteplase and to evaluate the association between thrombus dynamics and 3-month outcomes. Methods: This retrospective study analyzed prospectively collected, multicenter data from consecutive patients with LVO who underwent bridging therapy between January 2022 and December 2024. Thrombus dynamics were classified as resolution, migration, or stability. Analyses incorporated propensity score matching with weighting to balance baseline characteristics. Results: Of the 806 initially included patients, 746 were included after matching (373 treated with tenecteplase and 373 treated with alteplase). The incidence of thrombus migration was significantly higher in the tenecteplase group than in the alteplase group (19.3% vs. 11.3%; odds ratio [OR]: 1.92; 95% confidence interval [CI] 1.27–2.91). The advantage of tenecteplase over alteplase was restricted to patients with an IVT-to-puncture time of <60 minutes (18.6% vs. 6.2%; p=0.001) and was no longer significant when the interval ≥60 minutes (19.7% vs. 15.0%; p=0.204; pinteraction=0.043). Additionally, thrombus migration was associated with a better functional outcome (OR: 1.62; 95% CI 1.04–2.53). Finally, tenecteplase was associated with improved functional independence compared with alteplase (OR: 1.43; 95% CI 1.04–1.95). Conclusions Tenecteplase demonstrated superior efficacy in inducing thrombus migration compared with alteplase, particularly within 60 minutes of IVT administration. Thrombus migration independently predicted improved functional independence. These findings support the preferential use of tenecteplase for bridging therapy in patients with LVO.

Alacrima-achalasia-mental retardation syndrome(AAMR) is an extremely rare autosomal recessive genetic disorder caused by mutation in the GMPPA gene. Its pathogenesis is associated with congenital disorders of glycosylation. The clinical manifestations involve multiple system impairments, with alacrima, achalasia, and mental retardation as the core features. This article reports the diagnosis, treatment process and long-term follow-up outcomes after deep brain stimulation in one patient with AAMR complicated with dystonia, aiming to improve clinicians' understanding of this disease.

OBJECTIVE To evaluate the characteristics of adverse drug event （ADE） associated with five therapeutic agents for Gaucher disease（imiglucerase， velaglucerase alfa， taliglucerase alfa， eliglustat，and miglustat）. METHODS ADE reports related to the above five drugs were retrieved from the FDA Adverse Event Reporting System （FAERS） database from January 2004 to September 2025. The reporting odds ratio （ROR） and proportional reporting ratio （PRR） methods were applied for data mining. system organ class （SOC） and preferred term （PT） from the Medical Dictionary for Regulatory Activities （MedDRA， version 26.0） drug ADE terminology were used for classification and statistical analysis of ADE. RESULTS A total of 4 329， 1 740， 500， 1 329 and 998 ADE reports were retrieved for the aforementioned five drugs， respectively， generating 4 612， 2 605， 776， 1 157 and 2 185 ADE signals. These signals involved 26 SOC， affecting 25， 26， 16， 19， and 19 SOC， respectively. The predominant SOCs were various injuries， poisoning and procedural complications， as well as infections and infestations. The top one PTs of each drug were as follows： bone infarction， zinc deficiency， failure to perform drug monitoring steps， ichthyosis， abnormal nerve conduction examination. New suspected PTs included weight gain and spontaneous abortion for imiglucerase and velaglucerase alfa， weight gain for taliglucerase alfa and eliglustat， and neuropsychiatric manifestations such as dementia and apathy for miglustat. In terms of severe ADEs， other serious medical events were predominant for imiglucerase and taliglucerase alfa； prolonged hospital stays were the main severe ADE for velaglucerase alfa and eliglustat； and death was the leading severe ADE for miglustat. CONCLUSIONS In clinical medication， apart from common ADE，for imiglucerase， clinicians should be alert to bone infarction， weight gain and spontaneous abortion， and strengthen monitoring related to bones， metabolism and pregnancy. For velaglucerase alfa， attention should be paid to zinc deficiency， bone infarction， weight gain and spontaneous abortion， with focused monitoring of nutritional status and pregnancy risks. For taliglucerase alfa， failure to perform drug monitoring steps and weight gain require vigilance， and medication procedures should be standardized along with regular weight monitoring. For eliglustat， clinicians need to watch out for ichthyosis and weight gain and pay close attention to skin conditions. For miglustat， bone infarction， abnormal nerve conduction examination and dementia should be closely monitored， with enhanced surveillance on nervous system function， infections and prognosis of critically ill patients，to ensure patient medication safety.

Distinct from the complementary inhibition mechanism through binding to the target with three-dimensional conformation of small molecule inhibitors, targeted protein degradation technology takes tremendous advantage of endogenous protein degradation pathway inside cells to degrade plenty of “undruggable” target proteins, which provides a novel route for the treatment of many serious diseases, mainly including proteolysis-targeting chimeras, lysosome-targeting chimeras, autophagy-targeting chimeras, antibody-based proteolysis-targeting chimeras, etc. Unlike proteolysis-targeting chimeras first found in 2001, which rely on ubiquitin-proteasome system to mainly degrade intracellular proteins of interest, lysosome-targeting chimeras identified in 2020, which was act as the fastly developing technology, utilize cellular lysosomal pathway through endocytosis mediated by lysosome-targeting receptor to degrade both extracellular and membrane proteins. As an emerging biomedical technology, nucleic acid-driven lysosome-targeting chimeras utilize nucleic acids as certain components of chimera molecule to replace with ligand to lysosome-targeting receptor or protein of interest, exhibiting broad application prospects and potential clinical value in disease treatment and drug development. This review mainly introduced present progress of nucleic acid-driven lysosome-targeting chimeras technology, including its basic composition, its advantages compared with antibody or glycopeptide-based lysosome-targeting chimeras, and focused on its chief application, in terms of the type of lysosome-targeting receptors. Most research about the development of nucleic acid-driven lysosome-targeting chimeras focused on those which utilized cation-independent mannose-6-phosphonate receptor as the lysosome-targeting receptor. Both mannose-6-phosphonate-modified glycopeptide and nucleic aptamer targeting cation-independent mannose-6-phosphonate receptor, even double-stranded DNA molecule moiety can be taken advantage as the ligand to lysosome-targeting receptor. The same as classical lysosome-targeting chimeras, asialoglycoprotein receptor can also be used for advance of nucleic acid-driven lysosome-targeting chimeras. Another new-found lysosome-targeting receptor, scavenger receptor, can bind dendritic DNA molecules to mediate cellular internalization of complex and lysosomal degradation of target protein, suggesting the successful application of scavenger receptor-mediated nucleic acid-driven lysosome-targeting chimeras. In addition, this review briefly overviewed the history of lysosome-targeting chimeras, including first-generation and second-generation lysosome-targeting chimeras through cation-independent mannose-6-phosphonate receptor-mediated and asialoglycoprotein receptor-mediated endocytosis respectively, so that a clear timeline can be presented for the advance of chimera technique. Meantime, current deficiency and challenge of lysosome-targeting chimeras was also mentioned to give some direction for deep progress of lysosome-targeting chimeras. Finally, according to faulty lysosomal degradation efficiency, more cellular mechanism where lysosome-targeting chimeras perform degradation of protein of interest need to be deeply explored. In view of current progress and direction of nucleic acid-driven lysosome-targeting chimeras, we discussed its current challenges and development direction in the future. Stability of natural nucleic acid molecule and optimized chimera construction have a great influence on the biological function of lysosome-targeting chimeras. Discovery of novel lysosome-targeting receptors and nucleic aptamer with higher affinity to the target will greatly facilitate profound advance of chimera technique. In summary, nucleic acid-driven lysosome-targeting chimeras have many superiorities, such as lower immunogenicity, expedient synthesis of chimera molecules and so on, in contrast to classical lysosome-targeting chimeras, making it more valuable. Also, the chimera technology provides new ideas and methods for biomedical research, drug development and clinical treatment, and can be used more widely through further research and optimization.

BACKGROUND:Bone defects can directly affect the success rate and long-term stability of dental implants.Studies have shown that salidroside has the ability to promote the proliferation and differentiation of osteoblasts,but less is reported on its pathways related to osteogenic differentiation. OBJECTIVE:To investigate the effects of salidroside on the proliferation and differentiation of MC3T3-E1 cells and the expression of related genes and proteins through in vitro cell experiments. METHODS:Cell counting kit-8 test and alkaline phosphatase test were used to determine the optimal concentration of salidroside(0.5,1,5,10,and 50 μmol/L)in promoting the proliferation and differentiation of MC3T3-E1 cells.There were four groups in the experiment:control group,salidroside group,salidroside+LY294002 group,and LY294002 group,which were cultured with osteogenic induction solution,osteogenic induction solution containing 10 μmol/L salidroside,osteogenic induction solution containing 10 μmol/L salidroside+10 μmol/L LY294002,and osteogenic induction solution containing 10 μmol/L LY294002,respectively.The effects of salidroside and LY294002,an inhibitor of the PI3K/Akt signaling pathway,on the expressions of genes and proteins related to osteogenesis were observed. RESULTS AND CONCLUSION:Cell counting kit-8 assay and alkaline phosphatase assay showed that salidroside promoted the proliferation of MC3T3-E1 cells most significantly at 10 μmol/L.Compared with the control group,salidroside could promote mineralization,promote cell adhesion,reduce cell death,increase mRNA expression of Runx-2,osteocalcin and osteopontin(P<0.01),and increase protein expression of Runx-2 and p-Akt(P<0.01).However,the addition of LY294002 reversed the above results.These findings indicate that salidroside can promote the mineralization of MC3T3-E1 cells and the expression of osteogenesis-related genes and proteins,which may be related to the activation of PI3K/Akt signaling pathway.
