ObjectiveTo observe the effects of Xiaoyaosan on glucagon-like peptide-1 (GLP-1)/GLP-1 receptor (GLP-1r) and protein kinase A (PKA)/cAMP response element binding protein (CREB)/brain-derived neurotrophic factor (BDNF) signaling pathways in the hippocampal CA1 region of rats under chronic restraint stress (CRS),and to explore the mechanism of this formula to alleviate anxiety and depression-like behaviors. Methods40 specific pathogen-free male Sprague-Dawley (SD) rats were randomly divided into normal,model,Xiaoyaosan,and fluoxetine groups,with 10 rats in each group. CRS was used to induce anxiety and depression-like behaviors. The rats in the Xiaoyaosan group were gavaged with aqueous solution of traditional Chinese medicine formula granules (7.36 g·kg-1·d-1),while those in the fluoxetine group were gavaged with aqueous solution of fluoxetine (2 mg·kg-1·d-1). Body weight was measured on days 0,7,14,and 21 of the experiment. On days 0 and 22 of the experiment,the sucrose preference test (SPT),forced swimming test (FST),and open field test (OFT) were performed. The pathological morphology of the hippocampal CA1 region was observed by Nissl staining. The relative mRNA expression of post-synaptic density protein-95 (PSD95) and synapsin (SYP) was detected by reverse transcription quantitative real-time polymerase chain reaction. Immunohistochemistry and Western blot were used to detect expression of proteins in the GLP-1/GLP-1r and PKA/CREB/BDNF pathways in the hippocampal CA1 region. ResultsAfter CRS modeling,compared with the normal group,the rats of the model group had anxiety and depression-like behavioral manifestations,neuronal damage in the hippocampal CA1 region,significantly downregulated expression of synaptic plasticity markers PSD95 and SYP genes (P<0.01),and inhibition of GLP-1/GLP-1r and PKA/CREB/BDNF signaling pathways (P<0.05,P<0.01). Compared with the model group,the Xiaoyaosan group exhibited alleviated anxiety and depression-like behaviors,reduced neuronal damage in the hippocampal CA1 region, significantly increased expression of PSD95 and SYP genes (P<0.01),and the activation of the GLP-1/GLP-1r and PKA/CREB/BDNF signaling pathways (P<0.05,P<0.01). ConclusionXiaoyaosan can alleviate anxiety and depression-like behaviors in CRS rats by improving synaptic plasticity in the hippocampal CA1 region. The mechanisms may be related to the activation of the GLP-1/GLP-1r pathway and its mediated PKA/CREB/BDNF signaling pathway by the formula.

Objective:
The cross sectional study aimed to identify predominant co-occurrence patterns among six common mental health issues in college students, so as to provide empirical basis for designing targeted interventions.
Methods:
From October 2024, a total of 9 837 students from 4 universities in Xiangtan City, Hunan Province, participated in the current study by multistage random cluster sampling method. Participants completed self report measures, including the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder 7 item Scale (GAD-7), Young s Internet Addiction Diagnostic Questionnaire, the Adolescent Insomnia Symptom Self rating Scale, the Ottawa Self injury Inventory, and the Brief Community Assessment of Psychic Experiences Questionnaire. Demographic and co-occurrence characteristics were first compared using Chi square or trend Chi-square tests, followed by application of the Apriori algorithm to mine association rules for primary co-occurrence patterns.
Results:
The detection rate of co-occuring the common mental health issues was 46.44%. The detection rate was significantly higher in female than in male students (50.42%, 43.61%; χ 2=44.46) and in students from rural versus urban areas (47.22%, 44.60%; χ 2=5.67) (both P <0.05). Significant differences were observed among freshmen, sophomores, juniors, and seniors (46.63%, 48.35%, 45.05% , 43.66%, respectively; χ 2=9.22, P <0.05), although no statistically significant trend was detected ( χ 2 trend =3.75, P = 0.05 ). Association rule mining identified “anxiety + depression” “anxiety + psychotic experiences + depression” and “anxiety + sleep disorder + depression” as the combinations with the highest support. In addition, “anxiety+depression+Internet addiction+psychotic experiences =>sleep disorder (>= refered to the occurrence of the latter item under the condition that the former item occurs)” and “anxiety + depression+Internet addiction=>sleep disorder” were combinations with relatively high confidence.
Conclusions
Co-occurrence of these mental health issues among college students is high and exhibits diverse patterns. Strategies to address this burden should prioritize integrated interventions that target these specific combinations of factors.

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.

ObjectiveTo analyze the effects of the progestin-primed ovarian stimulation (PPOS) protocol on embryo euploidy rate and clinical pregnancy outcomes in infertile patients. MethodsWomen who underwent Preimplantation genetic testing for aneuploidy (PGT-A) cycles were selected as study participants (a total of 656 cycles and 3 081 blastocysts). Participants were divided into two age groups (≤35 years and >35 years) and further stratified by ovarian stimulation protocol: the Progestin-Primed Ovarian Stimulation (PPOS) group (n=48 and 60, respectively), the Luteal Phase Long Protocol (LP) group (n=160 and 57, respectively), and the Gonadotropin-Releasing Hormone Antagonist Protocol (AP) group (n=220 and 111, respectively). Baseline characteristics, ovarian stimulation outcomes, and embryo development parameters were compared among the three protocols within each age group. Additionally, clinical pregnancy outcomes of the first frozen embryo transfer (FET) cycle were compared. The primary outcome measure was the embryo euploidy rate. Results① In the ≤35 years age group, baseline follicle-stimulating hormone (bFSH) levels were significantly higher in the PPOS group compared to the LP and AP groups, and the bFSH/bLH ratio was significantly higher in the PPOS group than in the AP group (P < 0.05). In the >35 years age group, bFSH levels in both the PPOS and AP groups were significantly higher than in the LP group (P < 0.05).② In the ≤35 years group, there were no significant differences in the rates of metaphase II (MII) oocytes, 2-pronuclei (2 PN) zygotes, cleavage, 2 PN cleavage, blastocyst formation, high-quality embryos, or embryo euploidy between the PPOS group and either the LP or AP groups. However, the PPOS group showed significantly lower values for the following parameters compared to the other two groups: total oocytes retrieved, number of MII oocytes, number of 2 PN zygotes, number of cleaved embryos, number of 2 PN cleaved embryos, number of blastocysts formed, number of high-quality embryos, number of high-grade blastocysts, number of transferable embryos, number of cryopreserved embryos, number of biopsied blastocysts, number of euploid embryos, and the rate of obtaining at least one euploid embryo. In the >35 years group, no significant differences were observed among the PPOS, LP, and AP groups in the rates of MII oocytes, 2 PN cleavage, blastocyst formation, or in the number of euploid embryos, euploidy rate, and the rate of obtaining at least one euploid embryo. However, the PPOS group had significantly lower numbers of total oocytes retrieved, MII oocytes, 2 PN zygotes, cleaved embryos, 2 PN cleaved embryos, blastocysts formed, transferable embryos, and cryopreserved embryos compared to the LP group (P<0.05). The high-quality embryo rate was significantly lower in the PPOS group than in the AP group (P<0.05). The numbers of high-quality embryos, high-grade blastocysts, and biopsied blastocysts were significantly lower in the PPOS group than in both the LP and AP groups (P<0.05). Notably, the 2 PN fertilization rate was significantly higher in the PPOS group than in the AP group, and the cleavage rate was significantly higher in the PPOS group than in both the LP and AP groups (P<0.05).③ No significant differences were found among the three groups in the biochemical pregnancy rate, clinical pregnancy rate, live birth rate, early miscarriage rate, and late miscarriage rate following the first FET cycle. ConclusionCompared to the other two protocols, the PPOS protocol does not significantly affect embryo euploidy or clinical pregnancy rates. However, in freeze-all cycles with PGT-A, the PPOS protocol does not reduce the rate of chromosomally normal embryos but may decrease the total number of available embryos. It may not be the optimal choice for younger women, but it can be considered as a viable option for women of advanced maternal age.

With the continuous deepening of the concept of precision diagnosis and treatment for lung cancer, how to achieve higher efficiency and accuracy in the screening, diagnosis, and treatment pathways in clinical practice has become an important issue that urgently needs to be overcome. The current clinical difficulty lies in the fact that despite continuous advancements in imaging and molecular diagnostic technologies, there are still limitations in manual efficiency and subjective experience when it comes to massive data analysis and multi-scale feature extraction. Artificial intelligence (AI), especially algorithm systems based on deep learning, is an innovative technology capable of deeply empowering medical big data. This method utilizes algorithms such as convolutional neural networks, combined with radiomics, pathomics, and multi-modal data fusion analysis, demonstrating immense potential in early precise detection and benign-malignant differentiation of pulmonary nodules, digital pathological subtype recognition and non-invasive prediction of driver genes, precise 3D surgical planning and automatic delineation of radiotherapy target volumes, as well as dynamic risk warning during follow-up. This innovative technology provides a brand-new solution for realizing intelligent and individualized lung cancer diagnosis and treatment models. This consensus, based on the latest evidence from evidence-based medicine and combined with the development trends in the AI field and real-world clinical needs, was ultimately formed by gathering the consensus opinions of multidisciplinary experts in radiology, pathology, thoracic surgery, and other fields. The main content covers the application specifications of AI in the three core scenarios of lung cancer screening, diagnosis, and treatment, the technical standards for data collection and algorithm validation, as well as the ethical and regulatory challenges faced at the current stage. It aims to clarify the applicable boundaries of AI as a clinical auxiliary decision support tool, providing scientific guidance and standardized exploration directions for peers currently engaged in or planning to carry out AI-assisted clinical diagnosis, treatment, and translation of lung cancer.

ObjectiveTo evaluate the efficacy and possible mechanism of Wei's Huoxue Tongluo Formula (韦氏活血通络方,WHTF) in treating atrophic-stage non-arteritic anterior ischemic optic neuropathy (NAION) with qi deficiency and blood stasis. MethodsA total of 82 atrophic-stage NAION patients with qi deficiency and blood stasis were randomly divided into a treatment group and a control group, with 41 cases in each group. The treatment group was given oral administration of WHTF twice a day plus acupoint injection of distilled water 2 ml at Taiyang (EX-HN5) once daily, while the control group received injection of compound anisodine injection 2 ml at Taiyang (EX-HN5) once daily and oral administration of WHTF placebo twice a day. Both groups received treatment for a course of 14 days. The best-corrected visual acuity (BCVA), optic disc perfusion density (PD), flux index (FI), macular superficial PD, vascular density (VD), and traditional Chinese medicine (TCM) syndrome scores were compared between groups before treatment and on day 7 and day 14 of treatment. Additionally, mean defect (MD) and mean sensitivity (MS) of visual fields were measured before treatment and on day 14, along with safety evaluation. ResultsAfter treatment, both groups showed significant improvement in BCVA, visual field MD and MS, and TCM syndrome scores (P<0.05 or P<0.01). On day 14 of treatment, the TCM syndrome score in the treatment group was significantly lower than that in the control group (P<0.05). There was no significant improvement in optic disc PD and FI, and macular superficial PD and VD after treatment in either group (P>0.05) except that on day 7 the macular superficial foveal PD in the control group was significantly better than that in the treatment group (P<0.05). During the treatment period, no serious adverse events occurred in either group. ConclusionWHTF can improve the visual function indicators including visual acuity and visual field, as well as TCM syndrome scores in atrophic-stage NAION patients with qi deficiency and blood stasis. It shows clinical safety, although it does not appear to have a significant effect on optic disc or macular blood flow.

Objective To study the photodynamic performance and the killing effect of photodynamic therapy on lung cancer of novel chlorin compounds 2-(4-(5,15,20-triphenyl-7H,8H-porphyrin-10-yl) phenoxy) acetic acid(D1)and 4-(4-(5,15,20-triphenyl-7H,8H-porphyrin-10-yl) phenoxy) butanoic acid (D2). Methods The ultraviolet visible absorption spectrum and fluorescence spectrum of D1 and D2 were determined. The singlet oxygen generation capacity of D1 and D2 was measured by using DPBF as singlet oxygen capture agent. Fluorescence assay was used to detect the cellular phagocytosis rate of the compounds in A549 cells, and MTT assay was used to detect their dark toxicity and phototoxicity. A nude mouse model of lung cancer was established to investigate the antitumor activity of the compounds mediated photodynamic action in vivo, and the blood concentration of D2 in nude mice, its distribution in tumor tissue and skin tissue were further detected. Results D1 and D2 had strong absorption at 652 nm with the best excitation wavelength at 429 nm and 427 nm, and the optimal emission wavelength was at about 659 nm. They also had a higher singlet oxygen generation rate than the control drug m-THPC. D1 and D2 had no dark toxicity at concentrations below 10 μmol/L, and could be ingested by A549 cells, basically reaching saturation in 18~24 hours. After laser irradiation at 650 nm wavelength, D1 and D2 showed significant antitumor activity in vivo and in vitro (P<0.01). However, D2 could selectively accumulate in tumor tissues after administration, and the optimal treatment time was less than 30 min after administration. Conclusion D2 had excellent photodynamic antitumor activity and could selectively aggregate in tumor tissues, which had the potential to be a candidate drug for photosensitizer and treatment of lung cancer with independent intellectual property rights, and was worth further research.
