OBJECTIVE To optimize the simmering technology of Rheum palmatum from Menghe Medical School and compare the difference of chemical components before and after processing. METHODS Using appearance score， the contents of gallic acid， 5-hydroxymethylfurfural （5-HMF）， sennoside A+sennoside B， combined anthraquinone and free anthraquinone as indexes， analytic hierarchy process （AHP）-entropy weight method was used to calculate the comprehensive score of evaluation indicators； the orthogonal experiment was designed to optimize the processing technology of simmering R. palmatum with fire temperature， simmering time， paper layer number and paper wrapping time as factors； validation test was conducted. The changes in the contents of five anthraquinones （aloe-emodin， rhein， emodin， chrysophanol， physcion）， five anthraquinone glycosides （barbaloin， rheinoside， rhubarb glycoside， emodin glycoside， and emodin methyl ether glycoside）， two sennosides （sennoside A， sennoside B）， gallic acid and 5-HMF were compared between simmered R. palmatum prepared by optimized technology and R. palmatum. RESULTS The optimal processing conditions of R. palmatum was as follows: each 80 g R. palmatum was wrapped with a layer of wet paper for 0.5 h， simmered on high heat for 20 min and then simmered at 140 ℃， the total simmering time was 2.5 h. The average comprehensive score of 3 validation tests was 94.10 （RSD＜1.0%）. After simmering， the contents of five anthraquinones and two sennosides were decreased significantly， while those of 5 free anthraquinones and gallic acid were increased to different extents； a new component 5-HMF was formed. CONCLUSIONS This study successfully optimizes the simmering technology of R. palmatum. There is a significant difference in the chemical components before and after processing， which can explain that simmering technology slows down the relase of R. palmatum and beneficiate it.

Objective To establish a rat model of hyperuricemic nephropathy(HN)using a multifactorial induction method of potassium oxazinate combined with adenine and yeast feed to observe the intervention effect of Qiling granules(QLG).Methods Fifty-eight SPF-grade male SD rats were selected,and 10 rats were randomly allocated to the normal control(NC)group.The remaining rats were induced by multiple factors to establish HN rat models.After 2 weeks of modeling,submandibular blood samples were taken to detect serum UA,CREA,BUN,TG,and TC.Forty HN rats with bleeding clearance UA and body weight close to the mean were selected.They were randomly divided into a model(M)group,QLG low dose(QLG-L)groups,QLG high dose(QLG-H)group,and a positive control(PC)group,with 10 rats in each group,using a stratified randomization method.Each group was given corresponding drugs by gavage daily,and after continuous administration for 4 weeks,submandibular blood samples were taken to detect serum UA,CREA,BUN,TG,and TC.After euthanasia of the rats,liver tissue was taken to detect XOD and ADA activity.Renal tissue was taken for HE and Gomori hexamine silver staining,and the protein expression of GLUT9,OAT1,VCAM-1,and TGF-β in the kidneys was observed using immunohistochemistry and Western blot method.Results Compared with the NC group,the M group's serum levels of UA,CREA,BUN,TC,and TG,as well as liver XOD and ADA activities,were significantly increased(P＜0.01).The renal tissue of the model rats showed significant pathological changes.The area of renal tubules positive for urate and the expression of GLUT9,VCAM-1,and TGF-β proteins in the kidneys were significantly increased(P＜0.01,P＜0.05),while the expression of OAT1 was significantly reduced(P＜0.01).Compared with the M group,each treatment group showed significantly reduced serum UA levels,liver XOD,ADA activity,and renal VCAM-1 protein expression(P＜0.01,P＜0.05).The serum CREA and BUN levels and renal TGF-β protein expression of rats in the QLG-L group were significantly reduced(P＜0.05,P＜0.01).The serum CREA and BUN levels and renal GLUT9 protein expression of rats in the QLG-H group were also significantly reduced(P＜0.01,P＜0.05).The urate deposition and renal injury caused by each treatment were reduced to varying degrees,but there were no significant differences among groups(P＞0.05).Conclusions A stable HN rat model can be induced by gavage of potassium oxyzinate and adenine in combination with yeast feed.QLG can effectively treat HN by improving UA metabolic disorders,reducing the renal inflammation and urate deposition that cause renal damage in HN model rats.Its mechanism of action is related to a reduction in serum UA,CREA,BUN,and TG levels;liver XOD and ADA activities;and the expression of GLUT9,OAT1,VCAM-1,and TGF-β proteins in the kidneys.

Three novel sesquiterpenoid heterodimers,designated as auckcostusolides A-C(1-3),were isolated from Aucklandia costus leaves.The structures of compounds 1-3 were elucidated through comprehensive spectroscopic analysis,with their absolute configurations established using a combination of X-ray single-crystal diffraction and electronic circular dichroism(ECD)calculations.Notably,compounds 1 and 2,despite sharing identical planar structures derived from two identical sesquiterpenoids,exhibited oppos-ite configurations at C-11 and C-8'.This configurational difference can be attributed to distinct Diels-Alder cycloaddition processes between the sesquiterpenoid monomers.Additionally,the cytotoxic effects of compounds 1-3 were evaluated against colorectal can-cer HCT116 cells,fibrosarcoma HT1080 cells,and hepatocellular carcinoma HepG2 cells.Compounds 1-3 induced cell death was characterized by endoplasmic reticulum(ER)swelling and cytoplasmic vacuolization,typical morphological changes associated with paraptosis.Mechanistic studies revealed that compounds 1 and 3 triggered paraptosis-like cell death through the accumulation of react-ive oxygen species(ROS),activation of ER stress,and stimulation of the MAPK signaling pathway.

Objective:The Self-Compassion Scale(SCS)is used to evaluate self-compassion in general popu-lation.The study was designed to evaluate the validity and reliability of the Chinese version of SCS in patients with eating disorders.Methods:Ten experts in the related disciplines completed the content validity evaluation.A total of 136 patients who met the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)eating dis-order diagnostic criteria were surveyed with SCS to evaluate structural validity.Using the Rosenberg Self-Esteem Scale(SES),Satisfaction with Life Scale(SWLS),and Eating Disorder Examination Questionnaire 6.0(EDE-Q 6.0)as gold criterion,the criterion validity of SCS was measured.Twenty patients were selected for retesting to e-valuate test-retest reliability.Results:The item-level content validity index(I-CVI)of each item was between 0.70 and 1.00,and the average scale-level content validity index(S-CVI/Ave)was 0.96,indicating good content validi-ty.Factor analysis indicated a good fit for the six-factor model with reasonable factor loadings:x2/df=1.70,RM-SEA=0.07,CFI=0.92,TLI=0.91.The Chinese version of the SCS had an ICC of 0.31 with both SES and SWLS,and a negative correlation with EDE-Q 6.0 scores(r=-0.32).The test-retest reliability of the scale was 0.80.Conclusion:The Chinese version of the SCS has moderate validity and high reliability in patients with eating disorders,and can provide a clinical measure tool for psychological assessment in the Chinese population with eating disorders.

Objective:To investigate the effects of the Y-box binding protein 1(YBX1)on the proliferation and apoptosis of granulosa cells by regulating silent information regulator 1(SIRT1),and explore the differential ex-pression of YBX1 and SIRT1 of premature ovarian insufficiency(POI)patients and health controls,as well as its clinical significance.Methods:We recruited patients with POI and patients with normal ovarian function during in vitro fertilization(IVF)/intracytoplasmic sperm injection(ICSI)assisted pregnancy in the Department of Reproduc-tive Medical Center of the Fourth Affiliated Hospital of Jiangsu University from June 2022 to July 2023.The granu-losa cells and serum were collected.Western-Blot(WB)to detect YBX1 protein expression.Real-time quantitative polymerase chain reaction(RT-qPCR)to detect YBX1 and SIRT1 mRNA levels,and the correlation between the abundance of YBX1 and SIRT1 in serum and follicle stimulating hormone(FSH),luteinizing hormone(LH),estra-diol(E2),anti-Mullerian Hormone(AMH),and antral follicle count(AFC)were analyzed.5-bromo-2-deoxyuracil(EdU)and cell counting Kit-8(CCK8)were applied to detect cell proliferation;TdT-mediated dUTP-biotin nick end labeling assay(TUNEL)to detect cell apoptosis;RT-qPCR to detect cell proliferating cell nuclear antigen(PC-NA),B cell lymphoma 2(Bcl2),Bcl2 associated X protein(BAX),and cysteine-aspartate protease 3(Caspase-3)mRNA expression;RNA Immunoprecipitation(RIP)experiment to detect the interaction between YBX1 and SIRT1.Results:The expression of YBX1 protein and SIRT1 mRNA in granulosa cells and serum of POI patients were significantly lower than that of the control group(P＜0.05).The expression of YBX1 and SIRT1 mRNA in serum were negatively correlated with FSH,LH(r＜0,P＜0.05),and positively correlated with E2,AMH and AFC(r＞0,P＜0.05).Upregulating YBX1 in granulosa cells increased SIRT1 protein expression,SIRT1 mRNA stabili-ty,EdU positive rate,cell viability,PCNA mRNA expression level,Bcl2/BAX ratio(P＜0.05),while decreased Caspase-3 mRNA expression level,TUNEL positive rate(P＜0.05).Conclusions:The expression levels of YBX1 and SIRT1 in POI patients were significantly reduced and correlated with clinical ovarian function indicators.YBX1 can bind to SIRT1 mRNA and enhance its stability,which may promote the proliferation of granulosa cells,and in-hibit apoptosis.These findings suggested that YBX1 and SIRT1 are expected to become new targets for POI diag-nosis and treatment.
