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.

Femtosecond laser-assisted keratoplasty provides better advantages for personalized LASIK surgery. This article mainly introduces the commonly used femtosecond laser-assisted personalized LASIK surgery(FS-LASIK)in recent years, such as wavefront-optimized, wavefront-guided, topography-guided, Q value-guided(aspheric cutting), personalized surgery “Wavelight Plus” and personalized surgery when correcting patients with age-related inadequate accommodation. This article focuses on analyzing the advantages and disadvantages of different personalized FS-LASIK, as well as the research progress in recent years, and also focuses on comparing the differences between different personalized surgeries.

Objective: To investigate the efficacy，safety and feasibility of regional lymph node dissection in laparoscopic radical surgery for bladder cancer under the guidance of indocyanine green fluorescence imaging. Methods: A total of 30 patients with muscle invasive bladder cancer (T2/T3NxM0) who volunteered to enter the clinical trial were randomly divided into the indocyanine green imaging guided laparoscopic regional lymph node dissection group (n=15) and the standard pelvic lymph node dissection group (n=15).The number of positive lymph nodes，operation time，intraoperative bleeding volume，incidence of lymph leakage，and tumor recurrence and metastasis rate 2-year after surgery were collected. Results: The number of positive lymph nodes was (4.20±1.66) and (4.60±1.72) respectively in the indocyanine green and standard groups，with no statistically significant difference (P>0.05).There were no statistically significant difference in the tumor recurrence and metastasis rates 2-year after surgery between the two groups (P>0.05).However，the indocyanine green group had shorter operation time，less intraoperative bleeding volume，and lower incidence of lymphatic leakage than the standard group (P<0.05). Conclusion: Indocyanine green fluorescence imaging guided laparoscopic lymph node dissection has comparable clinical efficacy to standard lymph node dissection，but with fewer complications.

OBJECTIVE To prepare vancomycin hydrochloride （VH）-loaded polydopamine （PDA） nanoparticles （VH@PDA nanoparticles）， and study their antimicrobial effect in combination with photothermal therapy. METHODS Using PDA as the carrier， VH was loaded to prepare VH@PDA nanoparticles （PDA nanoparticles were prepared using the same method）. The nanoparticles were characterized with laser particle size analyzer， transmission electron microscope， and UV visible absorption spectrometer； the drug loading capacity and encapsulation efficiency of the nanoparticles were determined. The near-infrared laser irradiation was adopted to determine their photothermal ability. Taking Staphylococcus aureus as the research object， the bactericidal properties of the nanoparticles in combination with photothermal therapy in vitro were clarified through plate colony coating method， live/dead staining analysis， crystal violet staining. Using L929 cells as the research object， the effects of VH@PDA nanoparticles at different mass concentrations （0， 3.125， 6.25， 12.5， 25， 50 and 100 μg/mL） on cell viability were investigated to assess their biocompatibility. RESULTS VH@PDA nanoparticles were successfully loaded with VH， exhibiting uniform particle size （approximately 300 nm）， distinct pore size， and a spherical structure. The drug loading capacity was 11.34%， the encapsulation efficiency was 32.00%， the photothermal conversion efficiency reached 23.55%， and they demonstrated stable photothermal performance. The antibacterial effect results of the combined photothermal therapy demonstrated that without near- infrared laser irradiation， the antibacterial effects of VH， PDA nanoparticles， and VH@PDA nanoparticles were not significant. However， when subjected to near-infrared laser irradiation， VH@PDA nanoparticles exhibited a pronounced antibacterial effect. The results of the cell experiments revealed that after treatment with VH@PDA nanoparticles at various mass concentrations， the cell viability rates remained above 80%. CONCLUSIONS VH@PDA nanoparticles are successfully prepared， which exhibit stable photothermal properties， significant antibacterial effects when combined with photothermal therapy， and good biocompatibility.

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.

With the intensification of global aging,presbyopia has gradually become a global problem, and presbyopia correction surgery has emerged in recent years. The application of laser technology has brought great convenience to refractive surgery, and it also plays an increasingly important role in the correction of presbyopia. The emergence of excimer laser and femtosecond laser technology has opened a new world of surgical treatment for presbyopia, and brought new hope for surgical correction of presbyopia. In this paper, the application and new progress of excimer laser and femtosecond laser in presbyopia surgery are described.

As the search for effective treatments for COVID-19 continues, the high mortality rate among critically ill patients in Intensive Care Units (ICU) presents a profound challenge. This study explores the potential benefits of traditional Chinese medicine (TCM) as a supplementary treatment for severe COVID-19. A total of 110 critically ill COVID-19 patients at the Intensive Care Unit (ICU) of Vulcan Hill Hospital between Feb., 2020, and April, 2020 (Wuhan, China) participated in this observational study. All patients received standard supportive care protocols, with a subset of 81 also receiving TCM as an adjunct treatment. Clinical characteristics during the treatment period and the clinical outcome of each patient were closely monitored and analysed. Our findings indicated that the TCM group exhibited a significantly lower mortality rate compared with the non-TCM group (16 of 81 vs 24 of 29; 0.3 vs 2.3 person/month). In the adjusted Cox proportional hazards models, TCM treatment was associated with improved survival odds (P < 0.001). Furthermore, the analysis also revealed that TCM treatment could partially mitigate inflammatory responses, as evidenced by the reduced levels of proinflammatory cytokines, and contribute to the recovery of multiple organic functions, thereby potentially increasing the survival rate of critically ill COVID-19 patients.
