ObjectiveTo evaluate the effects of Wuhua herbal tea on chronic unpredictable mild stress (CUMS)-induced depression and explore its mechanism of action in combating depression.MethodsWe tested the antidepressant effects of Wuhua herbal tea in a rat model of CUMS-induced depression using fluoxetine as a positive control. The rats were divided into four groups: control group, model group, fluoxetine group, and Wuhua herbal tea group. The rats underwent body weight measurements, sucrose preference test, and open-field test. Enzyme-linked immunosorbent assay kits were used to detect the serum levels of serotonin, dopamine, adrenocorticotropic hormone (ACTH), corticosterone, norepinephrine, and interleukin-6. Intergroup comparisons and detection of brain-derived neurotrophic factor (BDNF), cAMP-response element binding protein (CREB), Janus kinase 2 (JAK2), and signal transducer and activator of transcription 3 (STAT3) mRNA expression in the hippocampus were performed using RT-PCR. Immunohistochemistry was used to identify the expression of phosphorylated JAK2 (p-JAK2) and phosphorylated STAT3 (p-STAT3) proteins in hippocampal paraffin sections of CUMS rats.ResultsCompared with the control group, the model group rats had depressive tendencies, exhibiting low vitality and interest in various behavioral indicators which were signs of despair. The Wuhua herbal tea group statistically increased the levels of serotonin and dopamine in the serum of CUMS rats to varying degrees (P = .015 and P = .002); reduced serum levels of ACTH, corticosterone, norepinephrine, and interleukin-6 (all P .05); and decreased mRNA expression of BDNF, CREB, JAK2, and STAT3 in the hippocampus (all P .05); and decreased p-STAT3 protein levels (P = .006).ConclusionWuhua herbal tea shows antidepressant potential in CUMS rats by modulating the HPA axis and inhibiting JAK2-STAT3 overactivation, alleviating neuroinflammation. It also restores BDNF-CREB pathway function, reducing depressive symptoms.

Gentiopicroside(GPS)is the main active ingredient extracted from Gentiaceae.It has anti-inflammatory,antioxidant,analgesic,anti-fibrosis,inhibition of tumor cell proliferation and improvement of glucose and lipid metabolism.Gentiaceae shows a wide range of application prospects in the treatment of diabetes,liver diseases,bone and joint diseases and other diseases.This paper reviewed the pharmacokinetics of gentiopicrin,including its pharmacokinetic properties in different animal models,and its mechanism and targets in the treatment of diabetes mellitus and its complications,liver injury,bone and joint diseases.Studies have shown that gentiopictin exerts its therapeutic effects by regulating various signaling pathways,such as PI3K/AKT,FOXO1,PPAR-γ,NF-κB,etc.Although the current research has made some progress,there are still limitations,such as most studies focused on animal models and in vitro experiments,lack of high-quality clinical evidence-based trials support.Future studies should further explore the new targets and signal transduction pathways of gentiopicroside,improve its bioavailability,and strengthen the research of traditional Chinese medicine compounds,so as to give full play to the advantages of holistic treatment of traditional Chinese medicine.

Objective:To evaluate the efficacy and safety of Rituximab (RTX) combined with short-term use of glucocorticoids in the treatment of the initial episode of steroid-sensitive nephrotic syndrome (SSNS).Methods:A retrospective case summary.A total of 30 children with SSNS treated in the Department of Intrarenal Rheumatism and Immunology, Xuzhou Children′s Hospital from December 2021 to March 2023, were enrolled in this study.They were given a standard dose of RTX (375 mg/m 2) and glucocorticoids for a short term.The patients were followed up for 1 year, and the general condition, changes in CD19 + B lymphocytes expression after RTX treatment, the relapse rate, the median relapse-free survival and adverse reactions of RTX were recorded.Kaplan-Meier method was used to analyze the relapse-free survival time. Results:CD19 + B lymphocytes were depleted 2 weeks after RTX treatment, and the median time required for CD19 + B lymphocytes reconstitution was 5 months after RTX treatment.The 1-year relapse-free rate was 90.00%, and the median relapse-free survival was 11 months.The glucocorticoid discontinuation rate was 93.33% in 3 months after RTX treatment, and 100% in 6 and 12 months after RTX treatment.Adverse reactions included infusion reactions in 7 cases (23.33%), neutropenia/leukopenia in 5 cases (16.67%), hypoimmunoglobulinemia in 10 cases (33.33%), infections in 4 cases.One case was complicated with severe influenza A virus infection after CD19 + B lymphocytes reconstruction. Conclusions:A standard dose of RTX can significantly reduce the relapse frequency, maintain long-term remission of proteinuria, and reduce the dose of glucocorticoids in patients at the initial episode of SSNS.Thus, it is worthy of clinical promotion.

Objective Based on the traditional Chinese medicine theory of"simultaneous regulation of the liver and kidney,"this study integrated network pharmacology prediction,molecular docking,and animal experimental validation to analyze the multi-target regulatory network of Duzhong Xionghua(the male flower of Eucommia ulmoides)-Sanqi Hua(Sanchi flower)herb pair(hereinafter called"herb pair")in modulating glucolipid metabolic disorders in type 2 diabetes mellitus(T2DM),thereby elucidating its underlying molecular mechanism.Methods Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform,China National Knowledge Infrastructure,VIP Database for Chinese Technical Periodicals,and Wanfang Data were used to obtain the active ingredients of the male flower of Eucommia ulmoides and Sanchi flower.PubChem Compound,SwissTargetPrediction,and SuperPred were used to screen and predict the targets of the drugs;The Human Gene Database,The Online Mendelian Inheritance in Man,and Therapeutic Target Database were used to screen the key gene targets of T2DM.A"component-target-pathway"network diagram was constructed using Cytoscape software,and Gene Ontology functional annotation and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis were employed to identify the functions of the relevant target genes and pathways.Molecular docking was used to verify the binding activities of the core components and the key targets.For animal experiments,spontaneous T2DM model mice were used,in which the normal group consisted of six mice(wild type)from the same litter,and the 24 successfully modeled mice were randomly divided into model,metformin(0.26 g/kg),high-dose herb pair(2.6 g/kg),and low-dose herb pair groups(1.3 g/kg)according to the blood glucose levels and body weights,with six mice per group.The drugs were administered by gavage daily for six consecutive weeks.The body weight and fasting blood glucose(FBG)levels were measured weekly,and an oral glucose tolerance test was performed in the fifth week.At the end of drug administration,body weight,naso-anal length,liver and bilateral epididymal adipose mass were measured;pathological changes in the liver were observed using HE staining;serum levels of aspartate transaminase(AST),alanine amino-transferase(ALT),total cholesterol(TC),triglyceride(TG),low-density lipoprotein cholesterol(LDL-C),and high-density lipoprotein cholesterol(HDL-C)were detected using colorimetric assay;and liver tissue phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT)/glycogen synthase kinase-3β(GSK-3β)signaling pathway protein expressions were determined using Western blotting.Results Network pharmacology screening identified 38 active components and 669 potential targets of the herb pair.Intersection analysis with 1,275 T2DM-related targets yielded 185 common targets.Protein-protein interaction network analysis and pathway enrichment revealed the PI3K/AKT signaling pathway as a key mechanism.Molecular docking confirmed the strong binding affinity of the core components to key targets such as AKT1,suggesting that the herb pair may activate the PI3K/AKT pathway and inhibit GSK-3β activity via beta-sitosterol etc.Animal experiments demonstrated that,compared with the model group,the metformin group exhibited reduced FBG,AST,and ALT levels(P<0.01),but failed to improve body weight,Lee's index,or epididymal fat coefficient.Both herb pair doses significantly lowered Lee's index,hepatic index,and the epididymal fat coefficient(P<0.01),with the low-dose herb pair group showing attenuated body weight gain in mice.In contrast,the high-dose herb pair group exhibited decreased FBG,improved glucose tolerance,reduced TC,TG,and LDL-C levels,and increased HDL-C level(all P<0.01).HE staining revealed that all metformin and the herb pair markedly restored hepatic structure and alleviated steatosis in model mice,with more pronounced effects in the high-dose group than in the low-dose group.Western blotting result indicated that in the low-dose herb pair group,phospho-PI3K(p-PI3K),AKT,and phospho-GSK-3β(p-GSK-3β)protein expressions significantly increased(P<0.05 or P<0.01),whereas GSK-3β decreased(P<0.05).The high-dose group exhibited enhanced PI3K,p-PI3K,AKT,phospho-AKT,and p-GSK-3β protein expressions(all P<0.01),accompanied by reduced GSK-3β expression(P<0.01).Conclusion The male flower of Eucommia ulmoides-Sanchi flower herb pair may ameliorate T2DM-related glucolipid metabolic disorders by modulating the PI3K/AKT/GSK-3β pathway.

Objective:To analyze the clinical efficacy of pasteurization-inactivated tumor bone replantation combined with intramedullary vascularized fibula for reconstructing bone defects after surgery for malignant bone tumors in children and adolescents.Methods:A retrospective analysis was performed on the data of 54 patients who underwent pasteurization-inactivated tumor bone replantation combined with intramedullary vascularized fibula reconstruction for bone defects after surgery for malignant bone tumors at the Bone and Soft Tissue Tumor Treatment Center of Peking University People's Hospital from September 2015 to September 2023. There were 39 males and 15 females, with an age of 12.4±5.6 years (range, 4 to 23 years). The tumor types included 33 cases of osteosarcoma, 19 cases of Ewing sarcoma, and 2 cases of soft tissue sarcoma. All cases were at Enneking stage IIB. The tumor locations were 30 cases in the femur, 19 cases in the tibia, 4 cases in the ilium, and 1 case in the humerus. The survival rate, bone healing time, tumor recurrence, and metastasis were observed. The limb function was evaluated using the Musculoskeletal Tumor Society (MSTS)-93 score.Results:All patients successfully completed the surgery and were followed up, with a follow-up time of 44.6±27.1 months (range, 12 to 96 months). The operation time was 527±132 min (range, 150 to 730 min), and the blood loss was 730±591 ml (range, 300 to 2,800 ml). The length of inactivated tumor bone was 16.5±4.5 cm (range, 9.1 to 24.0 cm), the defect length accounted for 43.4%±12.2% of the total length of the affected bone (range, 23.8% to 75.5%), the proximal osteotomy of the long bones in the extremities was 14.1±8.3 cm from the articular surface (range, 1.9 to 31.1 cm), the distal osteotomy was 9.4±6.2 cm from the articular surface (range, 1.7 to 22.9 cm), and the length of the harvested vascularized fibula was 18.0±4.0 cm (range, 11.0 to 26.4 cm). At the last follow-up, 51 patients were alive, including 47 with no evidence of tumor and 4 with tumor; 3 patients died of tumor progression. Local recurrence occurred in 5 patients, including 4 with soft tissue recurrence in the surgical area (3 underwent surgical resection and 1 received radiotherapy) and 1 with recurrence at the site of inactivated bone. Distant metastasis occurred in 11 patients, including 5 with lung metastasis only, 2 with bone metastasis only, and 4 with combined lung and bone metastasis. Among the 5 patients with lung metastasis only, lung metastases were resected, with 3 surviving with tumor, 2 surviving without tumor; the 2 patients with bone metastasis only underwent surgical resection of bone metastases, both surviving without tumor. Among the 4 patients with combined lung and bone metastasis, 3 died of tumor progression and 1 survived with tumor. The Kaplan-Meier curve showed a 5-year survival rate of 90.8%±6.2% and a 5-year recurrence-free and metastasis-free survival rate of 68.7%±7.9%. The osteotomy healing time at the diaphysis was 8.4±2.3 months (range, 4 to 13 months), the osteotomy healing time at the metaphysis was 5.9±1.7 months (range, 3 to 10 months), and the healing time between inactivated tumor bone and fibula was 6.4±2.0 months (range, 4 to 11 months). No nonunion occurred. The MSTS-93 score at the last follow-up was 94.4%±4.8% (range, 80% to 100%).Conclusion:Pasteurization-inactivated tumor bone replantation combined with intramedullary vascularized fibula reconstruction for bone defects after surgery for malignant bone tumors in children and adolescents has satisfactory clinical efficacy, high bone healing rate, and low rates of local recurrence and distant metastasis.
