Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

Aim To explore the protective effects and underlying molecular mechanisms of periplogenin(Ppg)in preventing acetaminophen(APAP)-induced drug-induced liver injury(DILI).Methods An APAP-induced liver injury model was established in vi-vo and in vitro.Liver/spleen indices were recorded,and serum aspartate aminotransferase(AST)and ala-nine aminotransferase(ALT)levels were measured.The pathological changes in liver tissue were observed using hematoxylin-eosin(HE)staining.The influence of Ppg on inflammatory cytokines(IL-6,TNF-α,IL-1 β)and key proteins within the associated signaling pathways was examined using enzyme-linked immu-nosorbent assay(ELISA),quantitative polymerase chain reaction(qPCR),and Western blot.Additional-ly,glutathione(GSH),malondialdehyde(MDA),and superoxide dismutase(SOD)activity levels were meas-ured.The expression of markers related to the NF-κB signaling pathway was assessed using qPCR,Western blot,and immunofluorescence.Results In vivo exper-iments showed that Ppg improved the liver and spleen index of mice with drug-induced liver injury,and the levels of AST and ALT in the serum decreased signifi-cantly,reducing the pathological damage of liver tis-sue.In vitro experiments showed that Ppg significantly inhibited the expression of IL-6,TNF-α and IL-1 β,and decreased the levels of GSH and MDA and in-creased SOD activity in AML-12 cells.Additionally,the inhibition of the NF-κB signaling pathway using pyrrolidinedithiocarbamate ammonium(PDTC),an NF-κB signaling pathway inhibitor reduced inflammato-ry cytokine expression and significantly decreased p65 nuclear translocation,showing results comparable to those observed in the high-dose Ppg group.Conclu-sions Ppg alleviates APAP-induced liver injury,po-tentially by inhibiting the NF-κB signaling pathway in hepatocytes,thereby reducing the inflammatory re-sponse and protecting liver from APAP-induced dam-age.

BACKGROUND:Foot position and seat height are important factors affecting "Sit-to-Stand",but most of the current research on "Sit-to-Stand" focuses on healthy people and Parkinson's disease patients. The kinematic and kinetic characteristics of the lower limbs of children with spastic cerebral palsy during the "Sit-to-Stand" task under different foot positions and seat heights are not known.OBJECTIVE:To investigate the effects of different foot positions and different seat height on lower limb kinematic and kinetic parameters during the "Sit-to-Stand" task in children with cerebral palsy. METHODS:Seven children with spastic cerebral palsy were selected as the research subjects. All subjects received the "Sit-to-Stand" test of six tasks,namely three seat heights (high,medium,and low stools) × two foot positions (front and back foot positions). The kinematic and dynamic data of children with cerebral palsy were collected under different foot positions and seat heights.RESULTS AND CONCLUSION:(1) The time characteristics results showed that the total time required for the children with cerebral palsy to perform the sit-to-stand transfer task was significantly smaller in the high stool condition compared to the low stool condition (P=0.046). (2) The kinetic results showed that at the moment of lifting,the knee flexion moment was significantly larger in the bipedal posterior condition than the bipedal anterior condition (P=0.049). The knee flexion moment was significantly smaller in the high stool condition compared to the medium stool condition (P<0.001). (3) It is concluded that raising the seat height and changing the foot position had an effect on the sit-to-stand transfer in children with spastic cerebral palsy. The children were able to perform the sit-to-stand maneuver with less motor compensation in the high-stool bipedal-rear position condition. Meanwhile,the high chair can be used as an aid to enhance the performance of sit-to-stand transfer in children with spastic cerebral palsy. The high stool bipedal hindfoot condition was the most effective in improving the sit-to-stand transfer in children with spastic cerebral palsy.

With the establishment of bio-psycho-social medical model,both social and psychological factors play an important role in the occurrence,development and treatment of diseases.Hypertension is a common chronic multiple disease in China,and patients are often complicated with depression and other e-motional disorders.The interaction between hypertension and depression significantly increases the risk of poor prognosis.Current studies have shown a bidirectional promoting relationship between hypertension and depression,and they have some com-mon pathogenesis.However,the specific mechanism of their co-morbidity has not been fully elucidated.Renin-angiotensin sys-tem(RAS)plays an important role in the regulation of hyperten-sion and depression and other emotions.It is composed of two antagonistic pathways.The balance is maintained by angioten-sin-converting enzyme 2(ACE2).Therefore,this article reviews the relationship and mechanism of RAS in hypertension,depres-sion and comorbid states,in order to provide new treatment ide-as for hypertension and depression.

Adipocytic tumors are the most common type of soft tissue tumors,which can be divided into lipomas and liposarcomas.Studies have found that benign lipomas resected from the same site can transform into liposarcomas,especially atypical lipomatous tumors(ALT),suggesting an underlying biological association.In this case,the patient underwent resection of a right neck mass in our hospital in 2017,and the pathology showed fibrolipoma.One year later,the mass recurred at the original site but was not treated.By 2023,the mass had significantly enlarged and extended deeply.MRI showed that the lesion had an unclear boundary with the surrounding fat,suggesting liposarcoma.Puncture and molecular pathology showed MDM2 gene amplification,and the diagnosis of ALT was made,which was confirmed by pathology after complete surgical resection.It can be seen that adipocytic tumors have great differences in biological behavior,and benign lipomas can transform into liposarcomas(especially ALT).Clinically,it is necessary to combine imaging,pathology and molecular detection(such as MDM2/CDK4)for differentiation to formulate treatment plans.

Aim To evaluate the bioequivalence of two oral preparations of rivaroxaban tablets(test preparation T and refe-rence preparation R)in fasting/postprandibular state in healthy Chinese subjects.Methods A randomized,open,single-dose,four-cycle,completely repeated crossover experiment was used in this study.A total of 70 healthy male and female subjects were enrolled,including 38 subjects in the fasting group and 32 sub-jects in the postprandial group.Rivaroxaban tablets(2.5 mg/tablet)were taken orally once per cycle and their reference preparations were tested.The plasma rivaroxaban concentration was determined by LC-MS/MS method.The pharmacokinetic parameters of rivaroxaban tablets were calculated by WinNonlin software,and the parameters were analyzed and processed.Re-sults The PK parameters of rivaroxaban tablets and reference preparations in fasting group were as follows:Cmax was(72.48±17.08)and(66.36±15.64)μg·L-1,respectively.AUC0-t were(383.49±101.06)and(370.43±102.16)h·ng·mL-1,and AUC0-inr were(389.58±102.28)and(375.84±103.01)h·μg·L-,respectively.Main PK parameters of subjects taking rivaroxaban tablets orally after meals:Cmax were(66.48±15.64 and 60.87±13.44)μg·L-1,AUC0-t were(404.44±72.58)and(381.80±79.93)h·μg·L-1,re-spectively.AUC0_inf was(410.88±73.55)and(393.64±69.71)h·μg·L-1,respectively.Under fasting and postmeal conditions,subjects took rivaroxaban test and reference prepara-tion orally,one tablet(2.5 mg/tablet)each time.The geometric mean of the main pharmacokinetic parameters of rivaroxaban in plasma(Cmax,AUC0-t,AUC0-inf)and their corresponding values had a 90％confidence interval ranging from 80.00％to 125.00％.No serious adverse events or unexpected adverse e-vents occurred in both groups.Conclusion Rivaroxaban tablets are bioequivalent and safe in vivo under fasting and postprandial conditions.

AIM To investigate the ameliorative effects of Compound Fufangteng Mixture(CFM)on cyclophosphamide(CTX)-induced immunosuppression in mice.METHODS Forty-eight male C57BL/6J mice were randomly divided into the blank control group,the model group,the levamisole hydrochloride group(40 mg/kg)and the low-dose,medium-dose and high-dose CFM groups(3.75,7.5,10 g/kg),with 8 mice in each group,and given respective intervention orally once daily for 14 days.On the 5th to 7th day of administration,with the blank control group given normal saline intraperitoneally,the other groups underwent intraperitoneal CTX injections(80 mg/kg).24 hours after the last administration,organ indices of thymus and spleen were calculated;splenic histopathological alterations were assessed by HE staining;serum levels of IL-2,IL-6 and IgG were quantified using ELISA;splenic CD4+,CD8+T lymphocytes,alongside CD86+and CD206+macrophages populations were analyzed by flow cytometry;and splenic expression of CD4,CD8 and F4/80 was evaluated by immunohistochemical staining.RESULTS In CTX-treated mice,CFM administration mitigated body weight loss;enhanced thymus weight and thymic index;ameliorated splenic immune cell populations,elevated serum levels of cytokines IL-2,IL-6 and IgG in serum;and upregulated splenic levels of CD45+CD3+T lymphocytes and F4/80+CD11b+macrophages,alongside increasing the expression of CD4,CD8 and F4/80 surface markers.CONCLUSION CFM alleviates CTX-induced immunosuppression state in mice by modulating immune cells,restoring immune function and enhancing anti-inflammatory and tissue repair capabilities.

Radiation-induced thrombocytopenia (RIT) faces a perplexing challenge in the clinical treatment of cancer patients, and current therapeutic approaches are inadequate in the clinical settings. In this research, oxymatrine, a new molecule capable of healing RIT was screened out, and the underlying regulatory mechanism associated with magakaryocyte (MK) differentiation and thrombopoiesis was demonstrated. The capacity of oxymatrine to induce MK differentiation was verified in K-562 and Meg-01 cells in vitro. The ability to induce thrombopoiesis was subsequently demonstrated in Tg (cd41:enhanced green fluorescent protein (eGFP)) zebrafish and RIT model mice. In addition, we carried out network pharmacological prediction, drug affinity responsive target stability assay (DARTS) and cellular thermal shift assay (CETSA) analyses to explore the potential targets of oxymatrine. Moreover, the pathway underlying the effects of oxymatrine was determined by Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses, Western blot (WB), and immunofluorescence. Oxymatrine markedly promoted MK differentiation and maturation in vitro. Moreover, oxymatrine induced thrombopoiesis in Tg (cd41:eGFP) zebrafish and accelerated thrombopoiesis and platelet function recovery in RIT model mice. Mechanistically, oxymatrine directly binds to toll-like receptor 2 (TLR2) and further regulates the downstream pathway stimulator of interferon genes (STING)/nuclear factor-kappaB (NF-κB), which can be blocked by C29 and C-176, which are specific inhibitors of TLR2 and STING, respectively. Taken together, we demonstrated that oxymatrine, a novel TLR2 agonist, plays a critical role in accelerating MK differentiation and thrombopoiesis via the STING/NF-κB axis, suggesting that oxymatrine is a promising candidate for RIT therapy.
