ObjectiveTo observe the effects of Danggui Shaoyaosan on macrophage polarization and renal inflammation in db/db mice with diabetic kidney disease （DKD）， and to explore its renal protective effects and underlying mechanisms. MethodsEight db/m mice were assigned to the normal group， and forty db/db mice were randomly divided into a model group， low-， medium-， and high-dose Danggui Shaoyaosan groups （8.39， 16.77， 33.54 g·kg^-1）， and an irbesartan group （0.025 g·kg^-1）. All mice were administered treatment by gavage for 12 consecutive weeks. General conditions of the mice were observed during the intervention. At the end of the 12-week intervention， 24-h urine samples were collected using metabolic cages， after which the mice were anesthetized for sample collection. Blood was collected by enucleation and centrifuged to obtain serum for the determination of glycated serum protein （GSP）， serum creatinine （SCr）， blood urea nitrogen （BUN）， total cholesterol （TC）， and triglycerides （TG）. The urinary albumin-to-creatinine ratio （UACR） was measured. Renal pathological changes were observed using hematoxylin-eosin （HE） staining， periodic acid-Schiff （PAS） staining， and Masson staining. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum tumor necrosis factor-α （TNF-α）， interleukin-10 （IL-10）， and monocyte chemoattractant protein-1 （MCP-1） levels. Immunofluorescence （IF） was performed to detect F4/80 expression in renal tissue， and immunohistochemistry （IHC） was used to assess CD206 expression. Real-time quantitative polymerase chain reaction （Real-time PCR） was employed to measure the mRNA expression of TNF-α， IL-10， inducible nitric oxide synthase （iNOS）， and arginase-1 （Arg-1）. Western blot analysis was used to detect the protein expression of iNOS， Arg-1， CD86， and CD206 in renal tissue. ResultsCompared with the normal group， the model group showed increased levels of GSP， UACR， SCr， BUN， TC， and TG， elevated levels of the inflammatory factor TNF-α and the chemokine MCP-1， and decreased IL-10 levels （P<0.01）. Pathological examination revealed glomerular hypertrophy， mesangial cell proliferation with marked mesangial expansion， inflammatory cell infiltration， vacuolar degeneration of renal tubular epithelial cells， prominent glycogen deposition， and increased collagen fiber deposition. In addition， relative F4/80 fluorescence intensity was enhanced， CD206 expression in the glomeruli and renal interstitium was reduced， and TNF-α and iNOS mRNA expression was increased. IL-10 and Arg-1 mRNA expression was decreased， iNOS and CD86 protein expression was increased， and Arg-1 and CD206 protein expression was decreased （P<0.05， P<0.01）. Compared with the model group， the Danggui Shaoyaosan groups and the irbesartan group showed decreased levels of GSP， UACR， SCr， BUN， TC， and TG， reduced serum TNF-α and MCP-1 levels， and increased IL-10 levels. Renal pathological damage was improved to varying degrees. Relative F4/80 fluorescence intensity was reduced， CD206 expression in the glomeruli and renal interstitium was increased， and TNF-α and iNOS mRNA expression was decreased. IL-10 and Arg-1 mRNA expression was increased， iNOS and CD86 protein expression was reduced， and Arg-1 and CD206 protein expression was increased （P<0.05， P<0.01）. ConclusionDanggui Shaoyaosan can improve renal function and alleviate renal pathological damage in db/db mice. Its mechanism may be related to inhibiting M1 pro-inflammatory macrophage polarization， promoting M2 anti-inflammatory macrophage polarization， reducing inflammatory responses， delaying the progression of renal fibrosis， improving renal pathological injury， and thereby exerting renal protective effects.

Depression is a common mental disorder that falls under the category of "stagnation syndrome" in traditional Chinese medicine （TCM）. Its complex pathogenesis poses challenges for the development of novel therapeutic agents. Currently， clinically used antidepressants are often accompanied by significant side effects， and statistics show that about one-third of patients do not respond to these medications. TCM demonstrates advantages in the treatment of depression through multi-target， multi-pathway and multi-mechanistic approaches. Pinelliae Rhizoma， a phlegm-resolving herb， exhibits effects such as drying dampness and resolving phlegm， as well as eliminating stuffiness and reducing masses. The characteristics of harmonizing Yin and Yang and resolving stagnation in the middle energizer align precisely with the pathogenesis of depression syndrome， demonstrating therapeutic efficacy in affected patients. Literature studies have found that the active ingredients of Pinelliae Rhizoma， such as cavidine， baicalein， β-sitosterol， as well as Pinelliae Rhizoma herb pairs， such as Pinelliae Rhizoma-Magnoliae Officinalis Cortex， Pinelliae Rhizoma-husked sorghum， Pinelliae Rhizoma-Prunellae Spica， exhibit significant antidepressant effects. Furthermore， TCM formulas containing Pinelliae Rhizoma as the principal therapeutic agent， such as Banxia Xiexin Tang， Banxia Houpo Tang， and Wendan Tang， as well as formulas incorporating Pinelliae Rhizoma like compound Xiaochaihu Tang， Chaihu Jia Longgu Muli Tang， and Erchen Tang， have also demonstrated favorable antidepressant efficacy. The antidepressant mechanism of these agents may involve modulation of 5-hydroxytryptamine （5-HT） and dopamine （DA） levels， up-regulation of brain-derived neurotrophic factor （BDNF） expression， regulation of the hypothalamus-pituitary-adrenal （HPA） axis， reduction of oxidative stress， modulation of nuclear transcription factor-κB （NF-κB） signaling pathway， and inhibition of microglia-mediated inflammatory responses. This review summarized the antidepressant mechanisms and clinical applications of the active components， herb pairs， and TCM formulas containing Pinelliae Rhizoma， aiming to provide a reference for modern research on the use of Pinelliae Rhizoma in antidepressant therapy.

Background/Aims: Liver transplantation (LT) following total hepatectomy is a life-saving treatment for hepatocellular carcinoma (HCC). The HCC recurrence after LT hinders the effectiveness of the procedure. The objective of this study is to develop a pre-operative risk stratification model based on a liquid biopsy. Methods: We conducted a comprehensive multi-omics study of 260 HCC patients from three centers, including clinical data, low-coverage whole-genome sequencing of cell-free DNA (cfDNA) from plasma, as well as whole-exome, single-nucleus RNA, and spatial transcriptomics from matched tumor and non-tumor tissues. Results: We identified cfDNA-derived copy number alteration (CNA) signatures associated with post-transplant recurrence. By integrating cfDNA-derived CNA profiles with single-cell transcriptomic data, we traced recurrence-associated cfDNA to a distinct subpopulation of malignant cells within the primary tumor. These cells were embedded in a pro-metastatic microenvironment of specialized endothelial subtypes and cancer-associated fibroblasts. Notably, most recurrence-associated lesions were detectable in cfDNA prior to liver transplantation (LT). Building on these insights, we developed the ZJU Criteria based on CNA fragments and tumor markers, a pre-LT risk prediction tool that integrates conventional clinical factors with cfDNA-derived CNA signatures, and validated it using internal and independent external cohorts. Conclusion Our findings suggest that post-transplant recurrence commonly originates from advanced subclones that emerge late during tumor evolution. The ZJU Criteria provides an accurate, non-invasive strategy that significantly improves pre-LT risk stratification and clinical decision-making for patients with HCC.

Cilia,as cellular sensory organelles,actively partici-pate in and regulate cellular processes such as autophagy and metabolic breakdown during their generation and transportation.Autophagy,on the other hand,is a cell self-protection mecha-nism that maintains cellular homeostasis by clearing aggregates and damaged organelles.Combining recent research findings,this review comprehensively elucidates the bidirectional crosstalk between primary cilia and autophagy.Specifically,it highlights the crucial role of cilia-dependent signaling pathways in activa-ting cellular autophagy and how autophagy regulates cilia genera-tion and length by degrading specific ciliary proteins.Moreover,the dysregulation of primary cilia and autophagy is closely asso-ciated with the clinical manifestations and pathogenesis of vari-ous ciliopathy-related diseases such as polycystic kidney disease and tuberous sclerosis.In terms of pharmacotherapy,this review provides a comprehensive and in-depth overview of small mole-cule inhibitors targeting ciliogenesis,including cytoskeletal drugs and Hedgehog signaling pathway inhibitors.Despite the current limitations in clinical use,these drugs lay the groundw-ork for developing highly specific targeted small molecule inhibi-tors of ciliogenesis and for the treatment of ciliopathies and canc-ers.By systematically discussing ciliogenesis,autophagy,disea-ses and drugs,this review offers new insights for further elucida-ting the crosstalk between ciliogenesis and autophagy,exploring their pathological mechanisms in disease development,and de-veloping therapeutic strategies in the future.

Objective To develop a single-person breast surgery teaching system to improve the teaching efficiency of breast surgery.Methods The single-person breast surgery teaching system consisted of a magnetic suspension and retraction device and a breast model.The magnetic suspension and retraction device was composed of a magnetic suspension component and a magnetic retraction component,of which,the magnetic suspension component included a bracket,an outer magnet and an inner magnet and the magnetic retraction component comprised a magnetic base and an elastic grasping forceps.The breast model was established with porcine abdominal tissue obtained from slaughterhouses.Twelve surgical trainees were randomized into an experimental group(n=6)and a control group(n=6),and the 2 groups performed flap release operations on the breast model with skin-preserving mastectomy as the target procedure.The operation was carried out with the developed system in the experimental group and with the traditional procedure in the control group.Results The two groups had the flap-free operation on the breast model finished successufully,which had no significant differences in the length of incision(P>0.05);the experimental group gained advantages over the control group in the number of assistants required,operation time,times of skin flap injuries,times of glandular injuries and effect of exposure,with the differences being statistically significant(all P<0.05).Conclusion The single-person breast surgery teaching system enhances the effect of exposure efficiently,meets the reequirements for single-person training and improves the teaching efficiency.[Chinese Medical Equipment Journal,2025,46(7):34-38]

Objective:To investigate the prognostic value and safety of thoracic radiotherapy in patients with synchronous oligometastatic, driver gene-negative non-small cell lung cancer (NSCLC) receiving immune checkpoint inhibitors (ICIs) as first-line treatment.Methods:Data were retrospectively collected from 55 patients diagnosed with synchronous oligometastatic, driver gene-negative NSCLC who received first-line ICIs from January 2017 to March 2022. These patients were categorized into two groups based on the administration of thoracic radiotherapy: the thoracic radiotherapy group ( n = 27) and the non-thoracic radiotherapy group ( n = 28). Comparative analyses were conducted to evaluate survival outcomes and safety profiles between the two groups. Results:Among the 55 patients, 27 (49.1%) received thoracic radiotherapy. The median follow-up time was 37.0 months (2.2-76.7 months). Patients in the thoracic radiotherapy group exhibited significantly improved median overall survival (OS: 53.4 vs. 21.3 months, P = 0.049) and median progression-free survival (PFS: 13.6 vs. 8.3 months, χ2=4.11, P = 0.043) compared to those in the non-thoracic radiotherapy group. Multivariate Cox regression analysis identified thoracic radiotherapy as an independent prognostic factor for OS ( HR = 0.39, 95% CI: 0.17-0.90, P = 0.027) and PFS ( HR = 0.53, 95% CI: 0.28-0.99, P = 0.046). The most common grade 3 or higher toxicity was bone marrow suppression, occurring in seven patients (12.7%). There was no significant difference between both groups in the incidence of grade 3 or higher treatment-related adverse events, including pneumonitis. Conclusion:In patients with driver gene-negative, synchronous oligometastatic NSCLC, first-line immunotherapy combined with thoracic radiotherapy may improve survival outcomes without increasing the incidence of severe treatment-related adverse events. Further large-scale, randomized prospective trials are needed to verify the findings of this study.

Objective To explore the association between psychological resilience and internet addiction among senior primary school students,so as to provide a scientific basis for formulating strategies for preventing internet addiction and enhancing psychological resilience in this group.Methods A stratified cluster sampling method was employed.In May 2021,a total of 1 618 fourth-and fifth-grade students from 5 primary schools in Jiading District,Shanghai were surveyed on psychological resilience and internet addiction through questionnaires.Independent sample t-tests,chi-square tests,and Logistic regression models were used for data analysis.Results Among the 1 618 students,the prevalence rate of internet addiction was 8.8%(142 students).The total score of psychological resilience(t=6.215,P<0.001)and the scores of three dimensions,namely family support(t=3.509,P<0.001),goal focus(t=6.965,P<0.001),and positive perception(t=5.887,P<0.001),of those reported with internet addiction were all significantly lower than those without internet addiction.Multivariate logistic regression analysis showed that compared with individuals with low psychological resilience,those with moderate(aOR=0.395,95%CI:0.267-0.584,P<0.001)and high psychological resilience(aOR=0.167,95%CI:0.077-0.365,P<0.001)had a lower probability of internet addiction.The three sub-dimensions of psychological resilience,namely goal focus,positive perception and family support,also showed a statistically significant negative association with internet addiction in these students.Conclusion Nearly one-tenth senior primary school students in Jiading District self-reported internet addiction.Higher levels of psychological resilience were associated with a lower probability of internet addiction among senior primary school students.Focusing on enhancing the goal focus,positive perception and family support dimensions in psychological resilience may be of great significance for preventing internet addiction among senior primary school students.

Background:Optimizing cultivation techniques for traditional Chinese medicine has become a crucial means to improve the quality of medicinal materials.Microbial agents,as environmentally friendly and efficient plant growth promoters and soil conditioners,have increasingly attracted attention in eco-agriculture research.Objective:Our understanding remains limited regarding how the application of microbial agents,alone or in combination,affects changes in the rhizosphere microbiome and its association with the bioactive components of medicinal materials.Methods:In this study,Epimedium pubescens Maxim.was employed as a model plant to examine the effects of 2 microbial agents(Paenibacillus mucilaginosus and Bacillus subtilis)applied individually and in combination on plant growth and the accumulation of bioactive components.Additionally,this study explored the relationship between the rhizosphere microbiome and plant development.Results:The application of microbial agents increased the yield of E.pubescens leaves by 20.30％to 33.66％and enhanced the total flavonol glycosides content by 11.40％to 29.94％.Meanwhile,microbial treatments reshaped the rhizosphere microbiome,promoted the enrichment of beneficial microorganisms(e.g.,Frankia and Paenibacillus),suppressed phytopathogenic fungi such as Didymella and Scytalidium,and enhanced the stability of the soil microbial co-occurrence network.The partial least squares path model suggested that microbial agents not only directly impact the quality of medicinal herbs but also indirectly alter the accumula-tion of bioactive components by modulating the soil microbiome.Conclusion:These findings deepen our understanding of the relationship between medicinal plant quality and rhizosphere micro-biomes as mediated by microbial agents.They also provide a basis for designing and manipulating synthetic microbial communities to promote sustainable development in eco-agriculture.

Objective:To investigate the clinical efficacy and safety of a baby smoothing and special caring cream in reducing the recurrence of atopic dermatitis (AD) in infancy.Methods:A randomized controlled trial was conducted. Children with moderate AD (with overall investigator's global assessment [IGA] scores of 3 - < 4) were enrolled from Shunyi Maternal and Children′s Hospital of Beijing Children′s Hospital from April 2021 to June 2024. During the induction period, all children were topically treated with 0.1% hydrocortisone butyrate cream twice daily on the lesional skin, as well as with a baby smoothing and special caring cream at least twice daily throughout the body; at the 2-week visit, patients with an IGA score of ≤ 1 point entered the maintenance phase, while those with an IGA score of > 1 point continued the treatment for another 2 weeks; at the 4-week visit, patients with an IGA score of ≤ 1 point entered the maintenance phase, while those still with an IGA score of > 1 point were withdrawn from the study, and received conventional treatment. Patients who entered the maintenance period were randomly divided into the test group and the control group in a 1∶1 ratio using a random number table. In the test group, the hydrocortisone butyrate cream was discontinued, while the baby smoothing and special caring cream was continued twice daily for 8 consecutive weeks; in the control group, both the hydrocortisone butyrate cream and the baby smoothing and special caring cream were discontinued. IGA and Scoring AD (SCORAD) scores were assessed by clinicians at weeks 4 and 8 in the maintenance phase, while the patient-oriented eczema measure (POEM) score was evaluated weekly by patients' parents. The Kaplan-Meier survival analysis and Breslow test were used to compare recurrence rates in the two groups (the primary efficacy outcome), and a generalized estimating equation model was used to evaluate the changes in IGA, SCORAD, and POEM scores in the two groups (the secondary efficacy outcomes). Adverse reactions were monitored throughout the study to evaluate safety.Results:A total of 68 children with moderate AD aged from 3 months to 2 years were included. There were 38 females and 30 males, aged 11.72 ± 6.03 months. Fifty-two patients entered the maintenance phase; 2 were lost to follow-up, and 50 were included in the per-protocol set, with 28 in the test group and 22 in the control group. The recurrence rate during the maintenance phase was 7.14% (2/28) in the test group and 31.82% (7/22) in the control group, showing a significant difference between the two groups ( χ 2 = 5.08, P = 0.032). At weeks 4 and 8 in the maintenance phase, the IGA scores were significantly lower in the test group than in the control group (Wald χ 2 = 5.06, P = 0.024), whereas the SCORAD scores showed no significant differences between the two groups (Wald χ 2 = 2.92, P = 0.087). During weeks 1 - 8 in the maintenance phase, the POEM scores showed no significant differences between the two groups or over time (both P > 0.05), while the two groups showed different change trends in POEM scores over time (Wald χ 2interaction = 55.37, Pinteraction < 0.001). Throughout the entire study period, no adverse reactions were observed among all 68 subjects. Conclusion:With a high safety profile, the baby smoothing and special caring cream could reduce the recurrence rate during the maintenance phase, showing promise as an adjuvant therapy for the maintenance treatment of AD in infancy, and is worthy of clinical application.
