OBJECTIVE To evaluate the efficacy and safety of total glucosides of paeonia (TGP) in the treatment of systemic lupus erythematosus (SLE). METHODS Randomized controlled trial (RCT) about TGP combined with western medicine versus western medicine alone for SLE treatment were retrieved from PubMed, Embase, Cochrane Library, Web of Science, CNKI, VIP, Wanfang Data, and CBM. The search period spanned from the inception of each database to June 1, 2025. After literature screening, data extraction, and quality assessment of the included studies, Meta-analysis was performed using RevMan 5.4 software. RESULTS Fifteen RCTs, involving 1 318 patients, were included. Meta-analysis results showed that compared with western medicine alone, TGP combined with western medicine significantly improved clinical efficacy [OR=4.96, 95%CI(3.41, 7.23), P<0.000 01], complement 3 [MD=0.18, 95%CI (0.13, 0.23), P<0.000 01] and complement 4[MD=0.08, 般021) 95%CI (0.04, 0.11), P<0.000 01], and reduced the levels of immunoglobulin G (IgG) [MD=-3.10, 95%CI (-3.59,-2.62), P<0.000 01], IgA [MD=-0.68, 95%CI (-0.78, -0.58), P<0.000 01], IgM [MD=-0.43, 95%CI (-0.53,-0.34), P<0.000 01], systemic lupus erythematosus disease activity index (SLEDAI) [MD=-1.59, 95%CI (-2.20, -0.99), P<0.000 01], recurrence rate [OR=0.23, 95%CI (0.13, 0.42), P<0.000 01] and the incidence of adverse drug reactions [OR= 0.54, 95%CI (0.36, 0.82), P=0.004]. CONCLUSIONS TGP therapy can improve clinical efficacy of SLE patients, promote the restoration of immunoglobulins and complements, reduce SLEDAI and recurrence rate and has good safety.

AIM:To analyze differential proteins associated with the pathogenesis of dry eye(DE)using bioinformatics methods, in order to reveal their potential molecular mechanisms.METHODS: Articles published in PubMed and EMBASE databases from the inception of the database to August 31, 2023, that used proteomic methods to detect protein expression in clinical samples of dry eye were searched. Differential proteins were selected and further analyzed using the STRING database and Cytoscape software for hub gene screening and module analysis. Protein-protein interaction(PPI)analysis, gene ontology(GO)functional annotation, and Kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment analysis were performed.RESULTS: A total of 21 articles were included, identifying 74 differentially expressed proteins. The most frequently occurring differential proteins were calgranulin A(SA1008), lipocalin-1(LCN1), lysozyme C(LYZ), mammaglobin-B(SCGB2A1), proline-rich protein 4(PRR4), transferrin(TF), and calgranulinB(S100A9). The top 10 hub genes were serum albumin(ALB), tumor necrosis factor(TNF), interleukin 6(IL6), IL1B, IL8, matrix metalloproteinase 9(MMP9), alpha-1-antitrypsin(SERPINA1), IL10, complement component 3(C3), and lactotransferrin(LTF). Module analysis suggested MMP9 and PRR4 as seed genes. KEGG analysis showed that differential proteins were mainly enriched in the IL17 signaling pathway(61.9%).CONCLUSION: The results reveal potential molecular targets and pathways for DE and confirm the association between the pathogenesis of DE and inflammation. Further in-depth research is needed to confirm the significance of these biomarkers in clinical practice.

Bisphenols (BPs) are extensively used in food packaging, personal care products, and plastics, making them prevalent in both living and working environments, which has raised significant concern. As endocrine-disrupting chemicals, BPs exert toxic effects on the female reproductive system by binding to estrogen receptors, thereby activating or inhibiting the expression of genes related to reproductive functions, which disrupts the normal function of the endocrine system. This paper reviewed the effects of bisphenol A (BPA), bisphenol S (BPS), and bisphenol F (BPF) on female reproductive function, focusing on three key aspects: the effects on the female reproductive organs, the occurrence of associated reproductive disorders, and the mechanisms of toxicity. Specifically, this review highlighted the effects on ovarian function, uterine morphology and function, and fallopian tube function, as well as their correlation with polycystic ovary syndrome, endometriosis, miscarriage, and eclampsia. Additionally, the toxic mechanisms of BPs exposure were summarized, providing a scientific basis for future research on the impact of BPs on the female reproductive system, as well as for the assessment of potential health risks and the development of preventive measures.

ObjectiveTo investigate the immunomodulatory effect of polysaccharides from Astragali Radix-Angelicae Sinensis Radix herb pair(Qi-gui polysaccharides) on lipopolysaccharide(LPS)-induced RAW264.7 macrophages and to characterize the structure of the active component Qi-gui homogeneous polysaccharide(AAPS-4a), and evaluate its protective effect on ulcerative colitis(UC). MethodsThe effects of six Qi-gui polysaccharides(0.01-100 mg·L-1) on the proliferation of RAW264.7 cells were assessed by cell proliferation and activity assay(CCK-8), and enzyme-linked immunosorbent assay(ELISA) was used to investigate the effects of the six polysaccharides(3, 10 mg·L-1) on the secretion levels of tumor necrosis factor(TNF)-α, interferon(IFN)-β, and nitric oxide(NO) in LPS-induced RAW264.7 cells. After screening for active polysaccharides, high-performance size-exclusion chromatography(HPSEC) was used to determine its homogeneity and relative molecular weight, then its characteristic functional groups were identified by Fourier transform infrared spectroscopy(FT-IR), monosaccharide composition was analyzed by high performance liquid chromatography(HPLC), methylation analysis combined with gas chromatography-mass spectrometry(GC-MS) was performed to determine the types and linkage modes of sugar residues, and one- and two-dimensional nuclear magnetic resonance(NMR) were used to identify the sugar residue composition and configuration of the active polysaccharide. Finally, experimental animals were divided into the normal group, model group, AAPS-4a low-dose group(50 mg·kg-1), AAPS-4a high-dose group(100 mg·kg-1), and sulfasalazine(SASP) group (75 mg·kg-1). Except for the normal group, the acute UC mouse model was induced using 3.5% dextran sulfate sodium salt(DSS). Each treatment group was administered the corresponding dose via oral gavage for 7 days, and changes in body weight were recorded. After treatment, the spleen index and disease activity index(DAI) score were calculated, TNF-α and interleukin-6(IL-6) levels in the serum were detected by ELISA, and histopathological changes in colon tissue were observed by hematoxylin-eosin(HE) staining. ResultsAt the cellular level, AAPS-4a exhibited a dose-dependent inhibition of LPS-induced increases in TNF-α, IFN-β, and NO levels(P<0.01). Structural characterization of AAPS-4a revealed that it was a homogeneous polysaccharide with a relative molecular weight of 7.6×103 Da, consisting of mannose(Man), glucose(Glc), and galactose(Gal) in a molar ratio of 1.3∶23.9∶1.0. It was primarily composed of five sugar residues of 1,6-α-D-Glcp, T-α-D-Glcp, 1,3-β-D-Galp, 1,4-α-D-Manp, and 1,2-α-D-Galp. In vivo experiments showed that compared with the normal group, the model group demonstrated markedly increased DAI score and spleen index, significantly reduced colon length, and significantly elevated levels of TNF-α and IL-6(P<0.01). Compared with the model group, the AAPS-4a high-dose group significantly reduced the DAI score and spleen index, as well as TNF-α and IL-6 levels, and improved colonic atrophy(P<0.05, P<0.01). Pathological observations showed that AAPS-4a significantly inhibited inflammatory cell infiltration in colon tissue and alleviated pathological damage. ConclusionAAPS-4a, a neutral homogeneous polysaccharide composed of 1,6-α-D-Glcp, T-α-D-Glcp, 1,3-β-D-Galp, 1,4-α-D-Manp and 1,2-α-D-Galp, is identified as a key bioactive component contributing to the anti-UC effect of the Qi-gui herb pair. Its immunoregulatory and anti-UC properties suggest its potential as a therapeutic agent for UC.

OBJECTIVE:
To investigate the effectiveness of digital three-dimensional (3D) assisted unilateral biportal endoscopy (UBE) in the treatment of highly isolated lumbar disc herniation (LDH) with translaminar approach.
METHODS:
The clinical data of 59 patients who met the selection criteria and underwent UBE treatment due to highly isolated LDH between January 2022 and December 2023 were retrospectively analyzed. Among them, 25 cases were treated with digital 3D assisted translaminar approach (observation group) and 34 cases were treated with interlaminar approach (control group). There was no significant difference in gender, age, disease duration, surgical segment, and preoperative visual analogue scale (VAS) score and Oswestry disability index (ODI) between the two groups ( P>0.05). The operation time, intraoperative blood loss, and lateral articular surface preservation rate were recorded and compared between the two groups. VAS score and ODI were used to evaluate the improvements of pain and function before operation and at 3 and 6 months after operation. The modified MacNab criteria was used to evaluate the effectiveness at last follow-up.
RESULTS:
One patient in the control group had dural tear, and the other patients had no nerve injury, infection, dural tear, or other related complications. There was no significant difference in operation time and intraoperative blood loss between the two groups ( P>0.05). Patients in both groups were followed up 6-13 months, with an average of 8.3 months. The lateral articular surface preservation rate in the observation group was significantly higher than that in the control group ( P<0.05). Three patients in the observation group and 2 patients in the control group had calf muscle venous thrombosis, which was cured after anticoagulant treatment with rivaroxaban and delayed exercise time. There was no recurrence or second operation during the follow-up period. The VAS score and ODI of the two groups at 3 and 6 months after operation significantly improved when compared with those before operation ( P<0.05). There was no significant difference between the two groups at each time point after operation ( P>0.05). At last follow-up, the effectiveness was evaluated according to the modified MacNab criteria, and there was no significant difference in the evaluation grade and excellent and good rate between the two groups ( P>0.05).
CONCLUTION
UBE via translaminar approach is safe and effective for the treatment of highly isolated LDH, which is beneficial to protect the facet joint, maintain spinal stability, and reduce soft tissue injury. With the assistance of digital 3D technique, preoperative planning can be performed accurately.

Objective:To investigate the factors influencing the occurrence of deep vein thrombosis(DVT)in patients with knee osteoarthritis after artificial total knee arthroplasty(TKA)and to construct a nomogram prediction model.Methods:A total of 120 patients with knee osteoarthritis underwent TKA from Dec 2020 to Dec 2022 were selected.The patients were divided into DVT group(n=20)and non-DVT group(n=100)according to whether DVT occurred after surgery.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of each influencing factor to the occurrence of DVT.Multivariable logistic regression was used to analyze the factors affecting the occurrence of DVT.The nomogram prediction model of DVT was constructed by the R software 4.0"rms"package.The calibration and decision curves were used to internally validate and clinically assess the predictive efficacy of the nomogram prediction model.Results:There were significant differences between DVT group and non-DVT group in age,body mass index(BMI),diabetes mellitus,hyperlipidaemia,plasma D-dimer level,operative time,intraoperative haemorrhage,post-operative bedrest,and anaesthesia modality(P<0.05).ROC curve showed that the AUC for age,BMI,plasma D-dimer,operative time,intraoperative haemorrhage,and postoperative bedrest were 0.663,0.678,0.985,0.856,0.925 and 0.925,respectively.Multivariable logistic regression analysis showed that age≥71 years old,BMI≥25.47 kg/m2,diabetes mellitus,hyperlipidaemia,plasma D-dimer level≥0.69 mg/L,and general anaesthesia were independent risk factors for postoperative DVT(P<0.05).The calibration curve of the nomogram prediction model was close to the original and ideal curves,with a C-index of 0.813(0.721-0.905),indicating a high degree of fit.The threshold value of the nomogram prediction model was>0.17,which could provide a net clinical benefit.And its net clinical benefit was higher than age,BMI,diabetes mellitus,hyperlipidemia,plasma D-dimer,and anaesthesia mode.Conclusions:The factors affecting the occurrence of DVT in patients with knee osteoarthritis after TKA are age,BMI,diabetes mellitus,hyperlipidaemia,plasma D-dimer level,operative time,intraoperative haemorrhage,postoperative bedtrest,and anaesthesia mode.The personalized neomorph prediction model constructed by these predictive factors can help to predict and evaluate whether DVT will be occurred in patients with knee osteoarthritis after TKA,so as to intervene early,reduce the incidence and improve the prognosis.

Purpose To evaluate the differential diagnostic value of 5.0T MRI susceptibility-weighted imaging(SWI)in hepatocellular carcinoma(HCC)and mass-forming intrahepatic cholangiocarcinoma(MICC).Materials and Methods A total of 56 patients with HCC and 36 patients with MICC confirmed by pathology from March 2023 to November 2024 in Anhui Provincial Hospital were retrospectively enrolled.Two radiologists independently analyzed three features of the lesions,including the low-signal rims around the lesion,hemorrhage within the lesion,and the relationship between lesions and adjacent vessels,on the SWI sequence between the two groups,respectively,via inter-rater consistency analysis.These above features between the two groups were compared and contrasted them with those obtained from conventional MR plain and enhanced scans,respectively.For intralesional hemorrhages,the diagnostic value was quantified by calculating the internal tissue susceptibility signal.Results The radiologists showed good consistency in the low-signal rims,intratumoral hemorrhage as well as the relationship between the lesion and the blood vessel on the SWI in the HCC group and the MICC group(Kappa=0.802-0.929,all P<0.001).Compared with conventional MR plain,SWI significantly enhanced the detection rates of perilesional low-signal rims and intratumoral hemorrhage(χ2=89.409,46.210,both P<0.001).These findings were more prevalent in HCC patients.The internal tissue susceptibility signal grading showed that HCC predominantly exhibited grade 3,whereas MICC predominantly exhibited grade 1,with statistically significant differences(Z=-4.059,P<0.05).Additionally,compared with enhanced MRI,SWI demonstrated higher accuracy in diagnosing the relationship between lesions and blood vessels in both groups;however,these differences were not statistically significant(χ2=0.275,0.247,P=0.871,0.619).In the HCC group,the relationship between tumors and blood vessels was primarily characterized by compression and tumor thrombus formation,while in the MICC group,it was predominantly marked by invasive changes,including vessel encasement,stenosis or occlusion,with a statistically significant difference between the two groups(Z=-6.809,P<0.001).Conclusion SWI sequence of 5.0T MRI provides clear visualization of the internal and peripheral structures of HCC and MICC.It can accurately delineate the relationship between lesions and blood vessels without the need for contrast agents,offering significant clinical utility in differentiating these two conditions.
