Primary cilia—those solitary, microtubule-based projections extending from the surface of most eukaryotic cells—are increasingly recognized not merely as cellular appendages, but as sophisticated signaling hubs. By compartmentalizing specific receptors (e.g., GPCRs) and effectors within a microdomain guarded by the transition zone, these organelles function effectively as high-gain sensors capable of integrating mechanical stimuli with metabolic cues. In this review, we examine the pivotal role of primary cilia across the nervous, bone-vascular, and renal landscapes, arguing for a unified “mechano-metabolic coupling” framework. Here, conserved ciliary modules are not static; rather, they are differentially deployed to uphold systemic homeostasis. Within the central nervous system, we position primary cilia as upstream integrators. We highlight how hypothalamic neuronal cilia concentrate metabolic receptors, such as the melanocortin 4 receptor (MC4R), to interpret energy status. Moreover, the recent identification of serotonergic “axon-cilium synapses” points to a direct mode of neurotransmission, wherein 5-HT6 receptors drive nuclear signaling and chromatin accessibility to rapidly modulate gene expression. Through these mechanisms, central cilia modulate sympathetic tone and neuroendocrine output, effectively establishing the mechanical and metabolic “boundary conditions” under which peripheral organs operate. Dysfunction in these central hubs is linked to obesity and neurodevelopmental disorders, including Bardet-Biedl syndrome. In peripheral tissues, cilia serve as versatile mechanotransducers that convert physical forces into biochemical responses. Regarding the bone-vascular system, we discuss the translation of mechanical loads and fluid shear stress into structural remodeling. In osteoblasts, specifically, ciliary integrity is intrinsically linked to cholesterol and glucose metabolism, fine-tuning the balance between Hedgehog and Wnt/β-catenin signaling to govern osteogenesis and bone repair. A similar dynamic exists in the vasculature, where endothelial cilia sense shear stress to modulate KLF4 expression and endothelial-to-mesenchymal transition—processes critical for valvulogenesis and vascular remodeling. Meanwhile, in the kidney, tubular cilia act as terminal effectors within a “shear-cilia-metabolism” axis. Here, fluid shear stress engages ciliary signaling to trigger AMPK-mediated lipophagy and mitochondrial biogenesis, thereby securing the ATP supply required for solute transport. Notably, dysregulation of this axis leads to metabolic reprogramming and aberrant proliferation, acting as a hallmark driver of cystogenesis in polycystic kidney disease (PKD). Crucially, this review attempts to dissect the often-conflated logic of cross-system integration by distinguishing 3 non-equivalent pathways: direct communication via ciliary extracellular vesicles, though this remains largely hypothetical in long-range signaling; “physiology-mediated cascades”, where ciliary dysfunction in a single organ—such as the kidney—precipitates systemic pathology through hemodynamic and metabolic shifts (e.g., altered blood pressure, fluid volume, or uremic toxins); and “parallel molecular defects”, where shared genetic mutations in ubiquitous components like the IFT machinery cause simultaneous, independent failures across multiple organ systems. Building on these distinctions, we propose a nested-loop model that links central set-points with peripheral feedback via physiological variables. Furthermore, we construct a “causality-to-translation” roadmap that pinpoints structural repair (e.g., targeting IFT assembly) and metabolic rescue (e.g., AMPK activation or autophagy induction) as promising therapeutic avenues. Ultimately, this framework provides a theoretical basis for deciphering the shared pathological mechanisms of multisystem ciliopathies, offering a strategic guide for the development of targeted interventions that go beyond symptomatic treatment.

Objective: To investigate the correlation between color parameters (L*, a*, b*, Eab*) and the contents of reducing sugars, total polysaccharides, total oligosaccharides, as well as four saccharides (fructose, glucose, sucrose, and kestose) during the nine cycles of steaming and sun-drying processing of Polygonatum kingianum, and to preliminarily explore the optimal processing duration.
Methods: The color changes were objectively evaluated using a colorimeter. The anthrone-sulfuric acid method was employed to determine total polysaccharides and oligosaccharides. The 3,5-dinitrosalicylic acid (DNS) colorimetric method was used to measure total reducing sugar content. High-performance liquid chromatography coupled with charged aerosol detection (HPLC-CAD) was applied for quantitative analysis of fructose, glucose, sucrose, and kestose. Multivariate statistical analysis was conducted to assess samples from different processing stages.
Results: Significant variations in color and component contents were observed across processing stages. The herbal pieces progressively darkened with increased processing cycles: brightness (L*) and total color difference (Eab*) initially decreased then stabilized, while a* (red-green) and b* (yellow-blue) values first increased then declined. Total polysaccharides and oligosaccharides showed overall decreasing trends, whereas reducing sugars initially increased before stabilizing. Fructose and glucose levels rose continuously, while sucrose and kestose decreased progressively, becoming undetectable after five cycles.
Conclusion: The chromatic alteration and saccharide composition of P. kingianum showed significant correlation with processing duration. Both total color difference (Eab*) and reducing sugar content stabilized after four processing cycles (12 hours), suggesting that four cycles of steaming and sun-drying may represent the optimal processing duration.

Objective: To investigate the correlation between the color parameters (L*, a*, b*, Eab* values) of Polygoni Multiflori Radix Praeparata powder prepared by different processing techniques and the contents of 2,3,5,4’-tetrahydroxystilbene-2-O-β-D-glucopyranoside, emodin, physcion, emodin-8-O-β-D-glucopyranoside, physcion-8-O-β-D-glucopyranoside.
Methods: The L*, a*, b* and Eab* values of Polygoni Multiflori Radix Praeparata powder prepared by different processing techniques were determined by spectrophotometer, and the contents of the five components were determined by high performance liquid chromatography. Secondly, SPSS 26.0 software and Simca 14.1 software were used to analyze the correlation.
Results: Through the hierarchical cluster analysis (HCA), it was found that the steamed samples and black bean steamed samples could be obviously divided into two categories: raw products and processed products. The processed products could be further divided into 2-8 h and 12-48 h. Pearson correlation analysis showed that the content of stilbene glycoside was significantly positively correlated with L*, a* and b* values (P<0.01). The a* value was significantly positively correlated with the content of emodin and physcion (P<0.01). Emodin-8-O-β-D-glucoside was positively correlated with L* value and b* value, while physcion-8-O-β-D-glucoside was negatively correlated with a* value. Partial least squares discriminant analysis (PLS) showed that 2,3,5,4’-tetrahydroxystilbene-2-O-β-D-glucoside (VIP=1.69) and emodin-8-O-β-D-glucoside (VIP=1.06) were the key variables affecting chromaticity characteristics (P<0.01).
Conclusion: The three processes of steaming, black bean steaming and black bean stewing are consistent in composition transformation and chromaticity variation, and stilbene glycoside can be used as a specific index component to characterize the processed color. Chromatic parameters can effectively reflect the processing progression and serve as quality monitoring indicators during production.

Diabetic microvascular complications (DMC) are major chronic complications of diabetes,primarily including diabetic kidney disease (DKD),diabetic retinopathy (DR),diabetic cardiomyopathy (DCM),and diabetic peripheral neuropathy (DPN). These complications significantly impact patients' quality of life and prognosis. Modern medicine primarily focuses on symptomatic control in the treatment of DMC,with limited ability to reverse the disease progression. Endoplasmic reticulum stress (ERS),as a central event under hyperglycemic toxicity,is not only a key cause of pancreatic β-cell dysfunction (reduced insulin synthesis and secretion) but also a core driver of damage in various target organs of DMC. It activates three signaling pathways of the unfolded protein response (UPR)-inositol-requiring enzyme 1 (IRE1),activating transcription factor 6 (ATF6),and protein kinase R-like endoplasmic reticulum kinase (PERK),intertwining processes such as autophagy,apoptosis,oxidative stress,and calcium homeostasis imbalance. Traditional Chinese medicine (TCM) offers multi-target and multi-pathway therapeutic advantages and can curb the pathological progression of DMC by regulating ERS. This article systematically reviews the relationships of ERS with pancreatic β-cell function,insulin synthesis,and insulin secretion,and elucidates the core signaling pathways through which ERS mediates DMC. Furthermore,it categorizes and summarizes experimental evidence and mechanisms of single medicinal herbs and their extracts,TCM compound formulas,and modern TCM preparations in regulating ERS for the treatment of various DMC subtypes. Finally,this article proposes ERS as a molecular bridge for integrating traditional Chinese and Western medicine in DMC treatment. Future research should leverage emerging technologies such as network pharmacology,multi-omics analysis,and nano-formulations to establish a synergistic network combining modern hypoglycemic drugs and TCM regulation of ERS. This approach is expected to achieve dual efficacy,enhance drug targeting and bioavailability,deepen the understanding of scientific connotation of TCM,and pave new avenues for the prevention and treatment of DMC.

ObjectiveTo observe the clinical efficacy and safety of Tianmeng Lingjiao Formula(天礞羚角方, TLF) as an adjunctive therapy for paroxysmal atrial fibrillation (PAF) with phlegm-heat harassing the interior syndrome. MethodsNinety patients with PAF and phlegm-heat harassing the interior syndrome were enrolled and randomly assigned in a 2∶1 ratio to test group (60 cases) and control group (30 cases). The control group received conventional western medicine, while the test group received TLF in addition to the conventional treatment, with one dose administered daily. The treatment course for both groups was 4 weeks. The efficacy of traditional Chinese medicine (TCM) syndrome and the rate of atrial fibrillation (AF) conversion were compared between groups. Assessments included AF burden, frequency and duration of AF episodes, TCM syndrome scores, and European Heart Rhythm Association (EHRA) AF symptom classification before and after treatment. Safety indicators such as blood routine, urine routine, stool routine, liver function, kidney function, and electrolytes were also monitored. Adverse events were recorded. ResultsA total of 82 patients completed the study (54 in the test group and 28 in the control group). After treatment, AF burden, the frequency and duration of AF episodes, and TCM syndrome scores were significantly reduced in both groups, and the test group showed lower indicators than the control group (P<0.01 or P<0.05). The AF conversion rate was 25.93% (14/54) in the test group, significantly higher than 3.57% (1/28) in the control group (P<0.05). The total effective rate for TCM syndrome efficacy was 83.33% (45/54) in the test group, which was significantly higher than 67.86% (19/28) in the control group (P<0.05). After treatment, the EHRA atrial fibrillation symptom severity in the test group showed significant improvement, and the improvement in atrial fibrillation symptoms was superior to that in the control group (P<0.01or P<0.05). No significant abnormalities were observed in safety indicators, and no adverse events occurred during the trial. ConclusionTLF as an adjunctive therapy can reduce AF burden, enhance the conversion rate of AF, decrease the frequency and duration of episodes, and improve clinical symptoms in patients with paroxysmal atrial fibrillation presenting with phlegm-heat harassing the interior syndrome, with a favorable safety profile.

Objective:To analyze the effect of influenza vaccination on influenza cluster epidemic in primary and secondary schools in Beijing during the 2023-2024 surveillance season and provide evidence for the improvement of influenza vaccination strategies.Methods:The incidence data of influenza cluster epidemic and influenza vaccination coverage in the schools in Beijing during 2023-2024 were collected. Descriptive epidemiological methods were used to analyze cluster epidemic characteristics, and χ2 test was used to compare incidence differences between groups, and OR value and vaccine effectiveness [VE=(1- OR)×100%] were calculated. A negative binomial regression model was used to evaluate the association between school vaccination rates and cluster epidemic risk. Joinpoint regression was used to analyze trends in relative risk ( RR) with increasing vaccination coverage and to determine the optimal vaccination threshold. Results:A total of 126 influenza cluster epidemic were reported in 115 primary and secondary schools in Beijing during 2023-2024 with the median size of 15 case, the average attack rate was 36.26% (2 033/5 607). The epidemics mainly occurred in urban area (70, 55.56%). Primary schools were the main setting (78, 61.90%), and influenza A(H3N2) was the predominant subtype (108, 85.71%). The overall influenza vaccination coverage in the primary and secondary students was 54.26%, while the average vaccination in classes affected by the epidemics was 58.57%. The overall protection rate was 47.62%, the protection rate was higher in primary schools (49.65%) than in secondary schools (46.60%). The protection rates against influenza A(H1N1)pdm09 (80.93%) and influenza B (Victoria lineage) (81.65%) were significantly higher than that against influenza A(H3N2) (44.19%). When school vaccination coverage reached ≥76.00%, the epidemic risk decreased by 52.82%.Conclusions:Even the match between influenza vaccine strains and circulating strains is suboptimal, increasing influenza vaccination coverage in schools can effectively reduce the risk for influenza cluster epidemic. In the future, measures such as policy guidance and public health education should be taken to further improve vaccination coverage, thereby establishing herd immunity and reducing the transmission risk of influenza in schools.

Rheumatic diseases are a group of chronic disorders characterized by abnormalities in the immune system, while portal hypertension occurs due to increased blood flow or heightened resistance in the portal venous system or obstruction of hepatic venous outflow. Both rheumatic diseases and their medications can lead to noncirrhotic portal hypertension. The hypercoagulable state associated with rheumatic diseases can result in thrombosis within the portal and hepatic venous systems, and damage to the intrahepatic portal system and hepatic sinusoidal endothelial system can lead to porto-sinusoidal vascular disease and hepatic sinusoidal obstruction syndrome. Moreover, drugs used for the treatment of rheumatic diseases may cause liver parenchymal injury, which further leads to liver fibrosis and cirrhosis, or they may damage the hepatic vascular endothelium and thus cause noncirrhotic portal hypertension. This article elaborates on the mechanisms and characteristics by which common rheumatic diseases and their therapeutic agents lead to portal hypertension, in order to provide insights and assistance for clinical diagnosis, treatment, and follow-up monitoring.

OBJECTIVE:
To observe the effect of "Zhibian" (BL54)-to-"Shuidao" (ST28) needling technique on the reproductive function of the mice with poor ovarian response (POR) and explore the molecular mechanism of acupuncture on early embryos after in vitro fertilization-embryo transfer (IVF-ET) in POR mice.
METHODS:
Of 70 female C57BL/6 mice, 60 mice with regular estrous cycle were screened and 30 of them were randomly divided into a blank group, a model group, and an acupuncture group, 10 mice in each one. Mice in the model and acupuncture groups were administered with tripterygium glycosides suspension (50 mg·kg-1·d-1) via gavage for 2 weeks to prepare POR models; while in the blank group, the mice received an equal volume of 0.9% sodium chloride solution via gavage. After successful modeling, mice in the acupuncture group underwent "Zhibian" (BL54)-to-"Shuidao" (ST28) needling technique, once daily, for 20 min each time and lasting 2 consecutive weeks. After intervention completion, subsequently, all the three groups underwent ovulation induction, orbital blood collection, and ovary extraction and fresh denuded oocyte collection. Denuded oocytes, after incubated, together with the sperms from 15 male C57BL/6 mice, were transferred into the oviducts of 30 donor pseudopregnant C57BL/6 female mice via IVF-ET; and the embryonic tissue was collected on day 7 of implantation. After successful modeling and intervention completion, the general conditions of mice in each group were observed, and the estrous cycle disorder rate was compared among the groups. After intervention completion, the numbers of oocyte, ovarian wet weight and ovarian index were recorded in each group; the levels of anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) in the serum were measured using ELISA; and ovarian morphology and mitochondrial ultrastructure were examined using HE staining and transmission electron microscopy. The transcriptome sequencing technology was employed to identify differentially expressed genes (DEGs) in early embryos of each group, followed by bioinformatics analysis; and the reversed DEGs with significant difference were verified using quantitative real-time PCR (qRT-PCR).
RESULTS:
After intervention, compared with the blank group, the mice in the model group presented poor spirits and declined water and food intake, reduced activity, the higher rate of estrous cycle disorder (P< 0.01); the decrease of the numbers of oocyte, ovarian wet weight, and ovarian index (P<0.01), reduced AMH and E2 in the serum (P<0.01), elevated FSH and LH in the serum (P<0.01); more atresia follicles in ovarian tissue, disorganized granulosa cells, reduced the numbers of mitochondria, vacuoles appeared and cristae breakage. When compared with the model group, in the acupuncture group, the spirits of mice, food intake and activity were improved, the rate of estrous cycle disorder was reduced (P<0.01); the numbers of oocyte, ovarian wet weight, and ovarian index were higher (P<0.01, P<0.05), the levels of AMH and E2 in the serum increased (P<0.01), the levels of FSH and LH in the serum decreased (P<0.01); the atresia follicles were reduced, the numbers of follicle increased at all levels, the numbers of mitochondria got higher, vacuoles and cristae breakage were declined. In comparison between the blank group and the model group, and between the model group and the acupuncture group, a total of 258 intersecting DEGs were identified, and 194 DEGs of them exhibited a trend of reversion before and after intervention. The top 5 reversed DEGs with significant difference included dexamethasone-induced Ras-related protein 1 (Rasd1), gene regulated by estrogen in breast cancer 1 (Greb1), leucine-rich repeat-containing G protein-coupled receptor 6 (Lgr6), Fraser syndrome 1 (Fras1), and apolipoprotein D (Apod). Compared with the blank group, the mRNA expression of Rasd1, Greb1, Lgr6, Fras1 and Apod in embryonic tissues decreased in the model group (P<0.01, P<0.05); and when compared with the model group, the mRNA expression of Rasd1, Greb1, Lgr6, Fras1 and Apod in embryonic tissues increased in the acupuncture group (P<0.05, P<0.01). These findings were consistent with the DEGs screening results. Gene ontology (GO) analysis revealed that the reversed genes of co-expression were primarily participated in the biological processes such as myoblast differentiation, endocardial cushion development, and cardiac morphogenesis. Kyoto encyclopedia of genes and genomes (KEGG) analysis indicated that the reversed genes of co-expression are enriched in the Wnt signaling pathway, and they were associated with various types of cardiac diseases.
CONCLUSION
The "Zhibian" (BL54)-to-"Shuidao" (ST28) needling technique may ameliorate the decline of ovarian response in mice with POR, promote normal follicle development and ovulation, thereby improve embryo quality and reduce the risk of developmental defects and deformity in the organs such as the embryonic heart. The underlying mechanism may be related to the regulation of the expression pattern of embryonic key genes through the Wnt signaling pathway.
