ObjectiveTo investigate the therapeutic effects and mechanism of decoctions from four kinds of processed products of Aconiti Radix Lateralis Praeparata(ARLP) in deficiency-cold syndrome. MethodsA total of 36 SD rats were randomly divided into the control group, model group, Shengfupian(SFP) group, Paofuzi(PFZ) group, Heishunpian(HSP) group and Paofupian(PFP) group with 6 rats in each group. Except for the control group, rats in other groups were administered hydrocortisone sodium succinate via intramuscular injection to induce a cold deficiency syndrome model. After 14 consecutive days, each ARLP decoction pieces was administered via continuous gastric lavage at a dose of 12 g·kg-1·d-1 for 7 d, while the control and model groups received an equivalent volume of physiological saline. After the end of administration, body weight, spleen weight and thymus weight were measured for calculating the spleen and thymus indexes. Hematoxylin-eosin(HE) staining was used to observe the pathological morphology of adrenal tissue. The fully automatic biochemistry analyzer was used to measure the total cholesterol(TC), triglyceride(TG), lactic dehydrogenase(LDH) and lactate(LAC) levels in serum. Enzyme-linked immunosorbent assay(ELISA) was employed to measure the contents of 17-hydroxycorticosteroid(17-OHCS), cortisol(CORT), triiodothyronine(T3), thyroxine(T4), thyrotropin(TSH), immunoglobulin(Ig) M, IgG, cyclic adenosine monophosphate(cAMP) and cyclic guanosine monophosphate(cGMP). Western blot was used to measure the protein expression levels of protein kinase A(PKA), cAMP response element-binding protein(CREB), silent information regulator 1(Sirt1) and peroxisome proliferator-activated receptor γ coactivator-1α(PGC-1α). And high performance liquid chromatography(HPLC) was used to determine the content of major alkaloids, followed by Pearson correlation analysis with pharmacodynamic indicators. ResultsAfter modeling, compare with the control group, the model rats exhibited symptoms such as lethargy and loose stools, mild abnormalities were observed in adrenal tissue structure, and both spleen and thymus indices were significantly reduced(P<0.01). Thyroid, adrenal and immune system functions were suppressed, with decreased serum cAMP level and significantly elevated cGMP level(P<0.01). Compared with the model group, the adrenal injury by hydrocortisone sodium succinate were repaired and the spleen index were increased significantly in all four ARLP groups(P<0.05, P<0.01). The thymus index in SFP and PFZ groups were increased significantly(P<0.05). The contents of T3, TSH, 17-OHCS and CORT were increased significantly in SFP and PFZ groups(P<0.05). In addition, the content of IgG in SFP, PFZ and PFP groups were increased significantly(P<0.01), while the content of IgM in PFZ and HSP groups were also increased significantly(P<0.05). Regarding the cyclic nucleotide system, PFZ significantly elevated cAMP level while reducing cGMP level(P<0.05), exhibiting the most pronounced effect among the four decoction pieces. For energy metabolism indicators, PFZ significantly improved abnormal markers including TC, TG, LDH, and LAC(P<0.05). HSP showed marked improvement effects on TG, LDH, and LAC(P<0.05). Both PFZ and SFP significantly elevated the expression levels of PKA, CREB, Sirt1, and PGC-1α proteins(P<0.01). Additionally, the diester alkaloids in ARLP showed a strong positive correlation with TG, IgG, and CORT, a strong negative correlation with LAC, a moderate positive correlation with T4, and moderate negative correlations with cAMP and spleen index. Monomeric alkaloids showed strong positive correlations with TG and IgG, strong negative correlations with LAC, moderate positive correlations with CORT and T4, and moderate negative correlations with cAMP and spleen index. However, the content of water-soluble alkaloids showed strong positive correlations with TC, LDH, 17-OHCS, T3, TSH, and thymus index, moderate positive correlations with cAMP, CORT, T4, and spleen index, and moderate negative correlation with cGMP. ConclusionAmong different processed ARLP decoction pieces, PFZ processed according to ZHANG Zhongjing's method exhibits the most potent warming and cold-dispelling effects. Its pharmacological actions are mediated through regulating the thyroid, adrenal, immune, cyclic nucleotide systems, and material-energy metabolism pathways. Among these, water-soluble alkaloids show strong or moderate correlations with more indicators of deficiency-cold syndrome and exhibit the highest content in PFZ. Therefore, PFZ processed according to ZHANG Zhongjing's method may exert its warming and cold-dispelling effects through water-soluble alkaloids.

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.

Objective To investigate the therapeutic effect of Huangkui capsules on targeted drug-related proteinuria in patients with hepatocellular carcinoma (HCC). Methods A retrospective analysis was conducted on clinical data of HCC patients with targeted drug-related proteinuria from June 2023 to December 2024 at Zhongshan Hospital, Fudan University. According to the treatment plan, patients were divided into the conventional treatment group and the Huangkui combination treatment group (Huangkui capsules combined with conventional treatment), and the clinical efficacy between the two groups was compared. The logistic regression analysis was used to identify the main factors affecting treatment efficacy. Results The Huangkui combination treatment group (n=29) showed a significantly higher overall effective rate (79.3% vs 42.3%, P=0.005), and an earlier proteinuria improvement (median time: 3 months vs 6 months, P=0.008) than the conventional treatment group (n=26) . The multivariate logistic regression analysis showed angiotensin-converting enzyme inhibitor (ACEI) or angiotensin Ⅱ receptor blocker (ARB) using (OR=0.190, 95%CI 0.045-0.808, P=0.025), targeted drug adjustment (OR=0.132, 95%CI 0.030-0.581, P=0.007), and Huangkui capsules using (OR=0.168, 95%CI 0.039-0.730, P=0.017) were protective factors for treatment efficacy of targeted drug-related proteinuria. Conclusions On the basis of conventional treatment, additive treatment with Huangkui capsules can alleviate targeted drug-related proteinuria faster and more effectively in HCC patients.

ObjectiveTranscranial magneto-acoustic stimulation (TMAS) is an emerging non-invasive neuromodulation technique that may provide a novel non-pharmacological intervention strategy for Parkinson's disease (PD). PD is characterized by the progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNc), leading to motor impairments such as bradykinesia, tremor, and rigidity. Increasing evidence indicates that mitochondrial dysfunction and impaired mitochondrial quality control are central mechanisms underlying dopaminergic neuronal loss. In particular, abnormalities in mitophagy and mitochondrial fission-fusion balance contribute substantially to oxidative stress, energy metabolic failure, and neuronal injury. At present, most clinical treatments for PD mainly alleviate symptoms but do not effectively halt disease progression. Therefore, exploring new interventions targeting the core pathological mechanisms is of considerable significance. This study aims to investigate whether TMAS can improve neural damage and motor dysfunction in PD mice by regulating mitophagy and the fission/fusion dynamic balance, thereby providing theoretical and experimental support for its application in PD treatment. MethodsMale C57BL/6 mice were used in this study. A PD model was established by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) for 7 consecutive days. After model induction, mice in the intervention group received TMAS once daily for 14 consecutive days, whereas the corresponding control group received sham stimulation. The stimulation target was positioned over the primary motor cortex (M1). Motor performance was evaluated using the pole test and the open-field test. To verify the activation effect of TMAS on the target cortical region, c-Fos immunohistochemistry was performed in the M1. To assess nigral dopaminergic neuronal injury, tyrosine hydroxylase (TH) immunohistochemistry was used to quantify TH-positive neurons in the SNc. Mitochondrial function was evaluated by measuring reactive oxygen species (ROS) levels and adenosine triphosphate (ATP) content in the SNc. Western blot was further performed to determine the expression of mitophagy-related proteins, including PINK1, Parkin, LC3-II, and p62, as well as mitochondrial dynamics-related proteins, including Drp1 and Opa1. ResultsTMAS significantly increased the number of c-Fos-positive cells in M1 (P<0.000 1), indicating effective activation of neurons in the targeted cortical region. Compared with the control group, MPTP-treated mice exhibited marked motor dysfunction, including a significant reduction in total distance traveled in the open-field test (P<0.000 1) and mean speed (P=0.000 1), as well as significant prolongation of turn time and total climbing time in the pole test (P<0.000 1). These behavioral impairments were accompanied by a substantial loss of TH-positive dopaminergic neurons in the SNc, whereas TMAS significantly increased TH-positive neuron survival (P<0.000 1). In parallel, MPTP induced a pronounced increase in ROS levels and a significant reduction in ATP content, indicating severe mitochondrial dysfunction and energy metabolism impairment (P<0.01). TMAS treatment significantly improved motor performance, as reflected by the reversal of MPTP-induced impairment in the open-field and pole tests, and significantly reduced ROS accumulation (P<0.01) while restoring ATP production (P<0.001). At the molecular level, MPTP markedly downregulated PINK1 and Parkin, decreased p62 expression, increased LC3-II accumulation, elevated Drp1 expression, and reduced Opa1 expression, whereas TMAS significantly reversed these abnormalities, suggesting restoration of mitophagy-related mitochondrial quality control and re-establishment of mitochondrial fission-fusion balance. Collectively, these findings indicate that TMAS ameliorates MPTP-induced neurotoxicity and restores mitochondrial homeostasis and energy metabolism. ConclusionTMAS effectively attenuates neural damage and improves motor dysfunction in MPTP-induced PD mice. Its neuroprotective effects are closely associated with multidimensional regulation of the mitochondrial quality control system, including restoration of PINK1/Parkin-mediated mitophagy and rebalancing of Drp1/Opa1-related mitochondrial dynamics. Rather than acting only as a symptomatic neuromodulatory intervention, TMAS may influence a key pathological axis of PD by improving mitochondrial homeostasis in SNc and protecting nigral dopaminergic neurons. These findings provide experimental evidence supporting TMAS as a promising non-invasive physical intervention for PD.

ObjectiveTo observe the clinical efficacy of Anzi Tiaochong decoction combined with aspirin and the effects of this therapy on the peripheral blood phospholipid antibody titers, coagulation function, and CD19+CD24hiCD27+regulatory B (Breg) cells in patients with obstetric antiphospholipid syndrome (OAPS) (pattern of kidney deficiency and blood stasis). MethodsPatients who meet the inclusion criteria were randomly allocated into an observation group (50 patients, with 4 patients dropped out and 46 patients completed) and a control group (50 patients, with 2 patients dropped out, 1 patient excluded, and 47 patients completed) through a random number table method. The control group was treated with aspirin enteric-coated tablets, 75 mg/time, once a day, and the observation group with Anzi Tiaochong decoction, 1 bag/day on the basis of the therapy in the control group. The treatment course for both groups was 8 weeks, and the patients were followed up for 4 weeks. The traditional Chinese medicine (TCM) symptom scores, titers of peripheral blood phospholipid antibodies [anti-cardiolipin antibody IgM (ACA IgM), anti-cardiolipin antibody IgG (ACA IgG), anti-β2-glycoprotein 1 antibody IgM (β2GP1-IgM), and anti-β2-glycoprotein 1 antibody IgG (β2GP1-IgG)], D-dimer (D-D), thromboelastography parameters [clotting factor activity (R), platelet function maximum amplitude (MA), coagulation composite index (CI), and clot strength (G)], CD19+CD24hiCD27+ Breg expression rate, and adverse drug reactions were recorded for the two groups before and after treatment. ResultsAfter treatment, both groups showed decreased ACA IgM, ACA IgG, β2GP1-IgM, β2GP1-IgG, D-D, MA, and G (P<0.05) and increased R (P<0.05). There was no statistically significant difference in CI. Compared with the control group, the observation group showed more significant decreases in TCM symptom scores and phospholipid antibody titers (P<0.05). After treatment, the expression rate of Breg in the observation group was higher than that before treatment (P<0.05).There was no significant difference in Breg expression rate before and after treatment in the control group. Neither group experienced significant adverse reactions. ConclusionAnzi Tiaochong decoction combined with aspirin can alleviate the symptoms, reduce the phospholipid antibody titers, and restore the coagulation status of patients with obstetric antiphospholipid syndrome (pattern kidney deficiency and blood stasis). It may exert the therapeutic effects by regulating Breg to maintain the patient's immune balance.

ObjectiveTo investigate the safety and efficacy of transparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy (EHL). MethodsA retrospective analysis was performed for the clinical data of 60 patients with large common bile duct stones who were admitted to Department of Gastroenterology, Jilin People’s Hospital, from May 1, 2023 to January 31, 2026, and according to the treatment method, the patients were divided into transparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group and peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group, with 30 patients in each group. The two groups were compared in terms of the rate of successful single-session stone fragmentation and removal, procedural time, duration of electrohydraulic lithotripsy, clinical success rate, and complications. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsCompared with the peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group, the transparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group had a significantly higher technical success rate (83.33% vs 60.00%, χ2=4.022, P=0.045) and significantly shorter procedural time [46.00 (42.25 — 49.00) min vs 54.50 (42.00 — 65.00) min, Z=2.012, P=0.044] and duration of electrohydraulic lithotripsy [8.00 (6.25 — 11.75) min vs 13.50 (9.25 — 17.75) min, Z=2.749, P=0.006]. Both groups achieved a clinical success rate of 100%, with no significant difference in the incidence rate of complications (P>0.05). ConclusionTransparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy has a high rate of successful single-session stone fragmentation and removal and a short procedural time, with good safety and efficacy, and therefore, it holds promise for clinical application.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

This article reports 2 cases of urinary retention in Alzheimer's disease with agitation treated by acupuncture. Based on patients' clinical symptoms, the etiology and pathogenesis were determined, and acupuncture was applied to Baihui (GV20), Sishencong (EX-HN1), Shenting (GV24), and bilateral Ciliao (BL32), Zhongliao (BL33), Fengchi (GB20), Taiyang (EX-HN5), etc. to regulate the mind and promote water metabolism. The positive and negative electrodes of the SDZ-Ⅴ type electroacupuncture device were attached to ipsilateral Ciliao (BL32), Zhongliao (BL33) respectively, with continuous wave, at the frequency of 15 Hz, and the current of 3 to 10 mA, depending on patients' tolerance. The needles were retained for 20 min. The treatment was delivered once every other day, 3 interventions a week and 12 interventions as 1 course. Both patients reported the micturition desire after 1 intervention with acupuncture and the catheter was removed on the same day. The urination was ameliorated without dysuresia after 1-2 courses of treatment, and the agitated behavior was alleviated. It can be the reference for the clinical treatment of urinary retention in patients with Alzheimer's disease with agitation.
