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.

Purpose To investigate the incidence and risk of malignancy(ROM)of the Bethesda class Ⅰ/Ⅲ di-agnosis of thyroid nodules due to insufficient number of follicular cells,and to analyze the correlation between their in-sufficient cell volume and the characteristics of the nodules themselves from the perspective of ultrasound and histology.Methods Clinical data were collected from fine needle aspiration cytology(FNAC)of the thyroid gland.Review and statistical analysis was performed on cases with the Bethesda class Ⅰ/Ⅲ diagnosis due to insufficient cell volume.The incidence and the ROM of Bethesda class Ⅰ/Ⅲ diagnosis were calculated.BRAF V600E(+)or postoperative patho-logical indicating papillary thyroid carcinoma(PTC)was used as the criterion for malignancy.Then,we matched the Bethesda class Ⅱ/Ⅵ cases with sufficient cell volume as the control group.The ultrasound characteristics and histo-logical images of the two groups were compared and analyzed in order to reveal the correlation between the insufficient amount of penetrating cells and the objective characteristics of the nodule itself.Results There were 39 solid thyroid nodules with the Bethesda class Ⅰ diagnosis,with an incidence of 3.3％and a ROM of 38.5％,and 160 nodules with the Bethesda class Ⅲ diagnosis,with an incidence of 13.5％and a ROM of 59.4％.The incidence and ROM of nod-ules with C-TIRADS ≥4b(22.4％,67.6％)were higher than those of C-TIRADS ≤4a(12.7％,39.8％),and the differences were statistically significant(P＜0.001).Compared to the Bethesda class Ⅱ/Ⅵ nodules with sufficient cell volume,occurrence of the Bethesda class Ⅰ/Ⅲ nodules were significantly correlated with small nodules(maximal diameter＜5 mm),vertical growth(aspect ratio ≥ 1)and poor blood supply(no or little blood flow signals)(r=0.131,-0.230,0.237,P=0.008,＜0.001,＜0.001).They were also significantly correlated with the pathologic histologic structure of diffuse significant fibrosis of the interstitium and low parenchyma/interstitium composition ratio(about 1:1)(r=-0.269,-0.396,P=0.019,＜0.001).Conclusion Thyroid Bethesda class Ⅰ/Ⅲ nodules have a high ROM,and BRAF V600E detection is recommended as a tool of tiered management.Bethesda class Ⅰ/Ⅲ diagnosis of insufficient cell volume is more likely when the nodules are too small,grow vertically and lack blood sup-ply,presumably associated with extensive interstitial fibrosis and sparse parenchymal cells.

AIM:To investigate the effects and underlying mechanisms of paeoniflorin(PF)on lipopolysac-charide(LPS)-induced intestinal injury in septic mice,using a combination of network pharmacology,molecular docking,and animal experiments.METHODS:Network pharmacology was used to identify key active components and therapeutic targets of Red Peony for treating sepsis.Molecular docking was performed to explore the binding affinity be-tween PF and silent information regulator 1(SIRT1).An LPS-induced mouse model of sepsis with intestinal injury was es-tablished.Samples were collected 24 h after modeling,and hematoxylin-eosin(HE)staining was performed to observe pathological changes in intestinal tissues.Chiu's scoring system was utilized to evaluate the extent of intestinal injury.En-zyme-linked immunosorbent assay(ELISA)was employed to measure levels of inflammatory factors in intestinal tissues,including interleukin-1β(IL-1β)and IL-18,as well as indicators of intestinal permeability such as diamine oxidase(DAO)and intestinal-type fatty acid-binding protein(I-FABP),alongside serum levels of D-lactate and the aerobic gly-colysis product L-lactate.Western blot analysis was performed to assess changes in protein levels of SIRT1,M2-type pyru-vate kinase(PKM2),and NOD-like receptor protein 3(NLRP3)in intestinal tissues.RESULTS:Network pharmacolo-gy suggested that paeoniflorin,an active component of Red Peony,treats sepsis by targeting SIRT1 among other proteins.Molecular docking revealed a strong binding affinity of PF with SIRT1.In vivo experimentation revealed significant patho-logical damage in intestinal tissues in the LPS group compared to the control group as evidenced by HE staining.Chiu's score,along with levels of IL-1β,IL-18,D-lactate,and L-lactate were significantly elevated,while DAO and I-FABP levels were reduced(P＜0.05).SIRT1 expression decreased,while PKM2 and NLRP3 levels increased(P＜0.05).In contrast,the LPS+PF group displayed reduced intestinal histopathological injury,lower Chiu's scores,and decreased levels of IL-1β,IL-18,D-lactate,and L-lactate,along with increased DAO and I-FABP levels(P＜0.05).Notably,SIRT1 protein expression increased while PKM2 and NLRP3 levels decreased(P＜0.05).Furthermore,compared to the LPS+PF group,the LPS+PF+EX527 group exhibited exacerbated intestinal histopathological injury,increased Chiu's scores,as well as elevated levels of IL-1β,IL-18,D-lactate,and L-lactate,alongside reduced DAO and I-FABP levels(P＜0.05),decreased SIRT1 expression,and increased PKM2 and NLRP3 levels(P＜0.05).CONCLUSION:Paeoni-florin effectively alleviates intestinal injury in mice with sepsis,potentially through the upregulation of SIRT1 expression and the inhibition of PKM2-mediated aerobic glycolysis,which subsequently reduces the activation of NLRP3 inflamma-somes,mitigates the release of inflammatory factors,and lessens intestinal inflammation.

Aim To investigate the effects of Agrimonia pilosa(AP)on the proliferation and apoptosis of non-small cell lung cancer(NSCLC)H1299 cells using non-targeted metabolomics and other methods,and to explore the underlying molecular mechanisms.Meth-ods Taking H1299 cells as the research object,the effect of AP on cell proliferation and apoptosis was de-tected through CCK-8 method,colony formation,LDH,Hoechst 33258 staining,AO/EB staining,flow cytometry detection,RT qPCR and other experiments.The main differential metabolites were detected by the metabolomics method of ultra-high phase liquid chro-matography and mass spectrometry(UHPLC-Q-Orbi-trap MS),and related metabolic pathways were ana-lyzed.Results Compared with the control group,AP treatment was able to significantly inhibit the prolifera-tion and colony formation of H1299 cells,while the re-lease of LDH increased in a dose-dependent manner.Fluorescence microscopy and flow cytometry and RT-qPCR analysis revealed that H1299 cells underwent crumpling and increased nuclear fragmentation after AP administration,blocked in G0/G1 phase,up-regulated apoptotic genes caspase-3 and Bax,and down-regulated apoptosis-inducing effects of Bcl-2.Metabolomics anal-ysis screened 35 differential metabolites,which were PC(O-30∶1),D-Glutamic acid,PE(18∶0/15∶0),etc.The main metabolic pathways involved includ-ed amino acid metabolism,glycerophospholipid metabo-lism and purine metabolism so on.Conclusions AP may exert its pharmacological effects by interfering with multiple metabolic pathways in H1299 cells,inhibiting cell proliferation and promoting apoptosis.

Aim To investigate the effects of the fangchinoline derivative LYY-32 on the biological prop-erties of the BLM642-1290 DNA helicase,in order to lay a foundation for further research on its antitumor activity.Methods Fluorescence polarization assay,malachite green-phosphate and ammonium molybdate colorime-try,and fluorescein-labeled DNA gel electrophoresis experiments were conducted to study the effects of fangchinoline derivative LYY-32 on the DNA binding activity,ATPase activity,and DNA unwinding activity of BLM642-1290 DNA helicase.The effects of LYY-32 on the DNA unwinding activity of DNA helicase in cells were studied using fluorescent techniques and time-lapse microscopy.Ultraviolet spectral scanning was used to investigate the effects of LYY-32 on the confor-mation of the BLM642-1290 DNA helicase.Results At a concentration of 10 μmol·L-1,the inhibition rate of LYY-32 on BLM642-1290 DNA helicase binding to dsDNA was 53.17％.At a concentration of 5 μmol·L-1,the inhibition rate of LYY-32 on BLM642-1290 DNA helicase binding to ssDNA was 88.49％.The inhibition rate of LYY-32 on the ATPase activity of BLM642-1290 DNA he-licase was 89.3％at a concentration of 50 μmol·L-1.When the concentration of LYY-32 exceeded 5μmol·L-1,its inhibition rate on the DNA unwinding activity of BLM642-1290 DNA helicase was 100％.LYY-32 also significantly inhibited the DNA unwinding ac-tivity of DNA helicase in cells.However,LYY-32 had no effect on the conformation of BLM642-1290 DNA heli-case.Conclusion The DNA binding activity,AT-Pase activity,and DNA unwinding activity of BLM642-1290 DNA helicase could be significantly inhibi-ted by the fangchinoline derivative LYY-32.

Objective:To analyze intestinal microecological differences and their correlation with psychological status in patients with constipated irritable bowel syndrome(IBS-C)and functional constipation(FC).Methods:A total of 160 patients with IBS-C and FC attending the outpatient and inpatient departments of the Department of Gastroenterology at the General Hospital of Ningxia Medical University from January 2021 to January 2024 were selected and grouped according to the type of disease into the IBS-C group(80 patients)and the FC group(80 patients),and 80 patients who had a health checkup during the same period were selected as the control group.Fresh fecal specimens were taken from all subjects,and 16S rRNA sequencing was used to detect the intestinal flora,and the indices of intestinal microecological diversity(Ace index,Chao index,Shannon index,and Sobs index)were detected,and the psychological state of the subjects was assessed by using the Self-Assessment Scale for Anxiety(SAS)and the Self-Depression Scale(SDS).Pearson's correlation method was used to analyze the correlation between intestinal microecology and correlation with psychological state in IBS-C and FC patients.Result:Bifidobacteria and Lactobacillus levels were lower in both the FC and IBS-C groups compared with the control group,and the decrease was more pronounced in the IBS-C group(P＜0.05).Enterobacteriaceae and Enterococci contents were higher in patients in the FC and IBS-C groups(P＜0.05),with the greatest increase in the IBS-C group(P＜0.05);Microbial diversity analysis showed that there were differences in Ace,Chao,Shannon and Sobs indices among the three groups(P＜0.05).All diversity indices were lower in the FC and IBS-C groups than in the control group,and the degree of reduction was more pronounced in the IBS-C group than in the FC group(P＜0.05);The SAS and SDS scores of both FC and IBS-C groups were higher than those of the control group,and the scores of the IBS-C group were higher than those of the FC group(P＜0.05);correlation analysis showed that,in the IBS-C and FC groups,Bifidobacterium and Lactobacillus,Ace index,Chao index,Shannon index,and Sobs index were negatively correlated with SAS and SDS scores.Enterobacteriaceae and Enterococci were positively correlated with SAS and SDS scores(P＜0.05).Conclusion:There are possible differences in the gut microbiota between IBS-C and FC patients.The imbalance of gut microbiota is more significant in IBS-C patients,and gut microbiota is closely related to psychological status.Clinical treatment of IBS-C and FC should pay attention to the regulation of gut microbiota and intervention of psychological status.

Objective·To explore the clinical efficacy and safety of sticky bone[deproteinized porcine bone mineral granules combined with advanced platelet-rich fibrin(A-PRF)and liquid platelet-rich fibrin(L-PRF)]in the repair of unilateral alveolar cleft.Methods·Patients diagnosed with unilateral alveolar cleft who met the inclusion and exclusion criteria were recruited from December 1,2023 to August 31,2024.The patients were randomly divided into 2 groups.The experimental group received sticky bone grafts,and the control group received autologous iliac cancellous bone grafts for alveolar cleft repair.The primary efficacy index was the bone resorption rate at 6 months post-surgery,calculated by measuring the grafted bone volume immediately after surgery and at 6 months using Simplant Pro 17.01 software based on patients'computed tomography data collected before surgery,immediately after surgery,and 6 months post-surgery.Secondary efficacy indices included bone density at 6 months after surgery,the occurrence of postoperative complications in patients,and the scores on the oral health-related quality of life scale.Prism 10 software was used for data analysis,and t-test and Pearson correlation analysis methods were adopted.Results·Seventeen patients with unilateral alveolar cleft were included in the experimental group,and 15 in the control group.The remaining bone volume in the experimental group at 6 months after surgery was more than that in the control group.The bone resorption rate in the experimental group was 33.24%±17.16%,significantly lower than 66.31%±17.98%in the control group(P<0.001).One patient in the experimental group had vestibular mucosal dehiscence accompanied by bone powder discharge 2 weeks after surgery;3 patients in the control group had vestibular mucosal dehiscence accompanied by cancellous bone discharge 1 month after surgery,with one case of grafted bone necrosis 4 months after surgery.The bone density in the experimental group at 6 months after surgery was significantly higher than that in the control group(P<0.001),and the scores on the oral health-related quality of life scale were lower.Conclusion·Compared with iliac cancellous bone,when sticky bone is used in the treatment of patients with unilateral alveolar cleft,it shows a lower bone resorption rate and higher bone density,indicating better osteogenic ability.Fewer number of complications and lower scores on the oral health-related quality of life scale suggest greater safety,thereby supporting its strong potential for clinical promotion and application.
