Objective To evaluate the efficacy of combining the replenishing qi and nourishing yin empirical formula with anti-vascular endothelial growth factor (VEGF) in diabetic macular edema (DME). Methods A retrospective analysis was conducted on 59 patients diagnosed with DME at Tongji Hospital of Tongji University or Shanghai Nanxiang Hospital, Jiading District from June 2019 to December 2022. Among them, 29 cases received intravitreal injection of ranibizumab (anti-VEGF group), while 30 cases received both intravitreal injection of ranibizumab and oral administration of the replenishing qi and nourishing yin empirical formula (combined treatment group). The best corrected visual acuity (BCVA), central macular thickness (CMT), and the traditional Chinese medicine (TCM) syndrome score were compared between the two groups before treatment and at 4, 8, 12, 16, 20, and 24 weeks after treatment. Results Compared with before treatment, BCVA significantly improved (P＜0.05) and CMT significantly decreased (P＜0.05) at different time points after treatment in both groups. At 16, 20, and 24 weeks after treatment, BCVA in the combined treatment group was superior to that in the anti-VEGF group (P＜0.01). At 12, 16, 20, and 24 weeks after treatment, CMT in the combined treatment group was lower than that in the anti-VEGF group (P＜0.01). Starting from week 8 after treatment, the TCM syndrome scores in the combined treatment group were lower than those in the anti-VEGF group (P＜0.01). Conclusions The replenishing qi and nourishing yin empirical formula could improve the efficacy of anti-VEGF therapy in DME patients, indicating that integrating traditional Chinese and Western medicine has certain clinical application value in treating DME.

[Objective]To explore Professor XU Guangxing's experience in differentiating and treating gastric cancer based on the"Yangming Weihe(stomach closed)"theory.[Methods]Through clinical shadowing,organizing and analyzing medical cases,and studying relevant literature,combined with Professor XU Guangxing's understanding of gastric cancer,this paper summarizes his experience in differentiating and treating gastric cancer based on the"Yangming Weihe"theory from the perspectives of theoretical connotation,etiology,pathogenesis and medication strategies.A medical case is included for validation.[Results]The theory of"Yangming Weihe"originates from the opening-closing-pivot theory.The Yangming closing mechanism serves as a component of the ascending and descending movement of Qi in the human body.Together with the Taiyin opening mechanism and the Jueyin closing mechanism,it collectively regulates the physiological functions of the stomach.Professor XU Guangxing proposes that the etiology and pathogenesis of gastric cancer can be categorized into three patterns:dysfunction of the Yangming closing mechanism;impaired Taiyin-Yangming opening-closing coordination;dual dysfunction of the Jueyin-Yangming closing mechanisms.His therapeutic strategies focus on:clearing heat,moistening dryness and promoting descending with bitter flavors to unblock Yangming;strengthening the spleen and harmonizing the middle-Jiao to support the opening-closing mechanism;dispersing wind pathogens and consolidating dissipation to restore the dual closing mechanisms.The attached medical case involved a postoperative gastric cancer patient,diagnosed as dual Jueyin-Yangming closing mechanism failure according to the"Yangming Weihe"theory.The treatment protocol emphasized:clearing dryness,nourishing Yin and unblocking-tonifying Yangming;dispersing wind,astringing dissipation and consolidating-descending Jueyin.The herbal regimen achieved stable and positive outcomes.[Conclusion]Professor XU Guangxing's approach to treating gastric cancer based on the"Yangming weihe"theory is characterized by unique insights into the etiology and pathogenesis,distinctive features in syndrome differentiation and treatment,and notable clinical efficacy.This methodology merits further research and broader promotion.

Animal experiments are essential tools in biomedical research, serving as a bridge between basic research and clinical trials. Systematic reviews and meta-analyses (SRs/MAs) of animal experiments are crucial methods for integrating evidence from animal experiment, which can facilitate the translation of findings into clinical research, reduce translational risks, and promote resource integration in basic research. With the continuous development of the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology, its application in SRs/MAs of animal experiments has gained increasing attention. This article first outlines the principles and specific applications of the GRADE methodology in SRs/MAs of animal experiments, including qualitative descriptive systematic reviews, meta-analyses, and network meta-analyses. It then deeply analyzes the misuse of the GRADE methodology in practice, including incorrect evidence grading, improper classification of evidence, misapplication in qualitative systematic reviews, inconsistencies between the documentation of the upgrading and downgrading process and results, and inappropriate use for making recommendations. Furthermore, this article comprehensively discusses the factors influencing the grading of evidence certainty in SRs/MAs of animal experiments, including the impact of bias risk, indirectness, inconsistency, imprecision, and publication bias on evidence downgrading, as well as the role of large effect sizes and cross-species consistency in evidence upgrading. Finally, in response to the issues discussed, improvement strategies are proposed, including further research and optimization of the GRADE methodology for SRs/MAs of animal experiments, the development of reporting guidelines tailored to the characteristics of SRs/MAs in animal experiment research, and enhanced professional training for researchers in the GRADE methodology. This article aims to improve the quality of evidence in SRs/MAs of animal experiments, strengthen their reliability in clinical decision-making, and promote the more efficient translation of findings from animal experiment research into clinical practice.

Objective:To investigate the efficacy and safety of electric microneedling combined with recombinant collagen liquid dressing, compound glycyrrhizin tablets, and hydrocortisone butyrate ointment for the treatment of mild to moderate alopecia areata in children.Methods:This is a prospective study. A total of 72 children with mild to moderate alopecia areata, admitted to the Department of Dermatology, Zunyi Maternal and Child Health Hospital from November 2023 to June 2024, were included in this study. The children were randomly assigned to either the experimental group, which received electric microneedling combined with treatment, or the control group, which received treatment without microneedling, based on the order of their visits. All patients received oral compound glycyrrhizin tablets and topical hydrocortisone butyrate ointment for treatment. In the experimental group, electric microneedling was used to puncture the alopecia lesions while simultaneously applying recombinant collagen liquid dressing. The control group did not receive electric microneedling treatment and only had the recombinant collagen liquid dressing applied to the lesions. The treatment lasted for 12 weeks. The efficacy and incidence of adverse reactions were compared between the two groups. After treatment, all patients were followed up for 3 months to check for any recurrence of this condition.Results:There was no significant difference in response rate between the experimental and control groups [81.58% (31/38) vs. 73.53% (25/34), χ2 = 0.67, P = 0.412). No significant difference in cure rate was observed between the experimental and control groups [57.89% (22/38) vs. 47.06% (16/34), χ2= 0.85, P = 0.358]. The time to effect in the experimental group was shorter than that in the control group [(3.16 ± 0.73) weeks vs. (4.60 ± 1.08) weeks, t = 5.15, P < 0.001]. The incidence of adverse reactions did not differ significantly between the experimental and control groups [7.89% (3/38) vs. 0, Fisher value = 0.24, P = 0.242]. There was no significant difference in recurrence rate between experimental and control groups [6.45% (2/31) vs. 12.00% (3/25), χ2 = 0.06, P = 0.801). Conclusions:The combination of electric microneedling, recombinant collagen liquid dressing, compound glycyrrhizin tablets, and hydrocortisone butyrate ointment provides a rapid onset of effect and is safe and effective for the treatment of mild to moderate alopecia areata in children.

Fatty liver is common disease of nutritional metabolism in the perinatal period,character-ized by elevated levels of NEFA in the blood and disorders of lipid metabolism.High concentra-tions of NEFA damage mitochondria and promote the release of reactive oxygen species(ROS).At the same time,lipid peroxidation occurs in lipid accumulation in hepatocytes,producing free radi-cals such as ROS,which leads to oxidative stress in the liver.When the level of intracellular ROS increases,thioredoxin-interacting protein(TXNIP)activates nucleotide-binding oligomerization structure-like protein 3(NLRP3)inflammasomes,and oxidative stress can regulate pyroptosis,but it is unclear whether reactive oxygen species(ROS)produced by oxidative stress in hepatocytes can mediate pyroptosis and induce liver injury in dairy cows through the TXNIP/NLRP3 pathway.In this study,liver tissue samples from healthy dairy cows and fatty liver cows were collected,and NEFA was used to construct a fatty liver cell model,and triglyceride(TG)content and oxidative stress related indicators were detected by kit.Western blot was used to detect the activation of NL-RP3 inflammasomes,the inflammatory pathway of NF-κB and the expression levels of pyroptosis-related proteins.Fluorescence quantitative PCR was used to detect the relative expression level of inflammatory factor mRNA.The results showed that compared with the healthy(control)group,the TG content of fatty liver tissue and fatty liver cells was significantly increased(P＜0.05),the activities of SOD and GSH-Px were significantly decreased(P＜0.05),and the protein expression levels of TXNIP,NLRP3,GSDMD-N and Caspase-1 were significantly up-regulated(P＜0.05).The results of the antioxidant model of fatty hepatocytes using NEFA and antioxidants(NAC)showed that compared with the fatty hepatocyte model,the content of ROS in hepatocytes was sig-nificantly reduced,and oxidative stress,NLRP3 inflammasome activation and pyroptosis were alle-viated.In summary,this study found that when fatty liver disease occurs in dairy cows,ROS pro-duced by oxidative stress in the liver can mediate pyroptosis through the TXNIP/NLRP3 path-way,which can lead to liver injury in fatty liver cows.

Objective To investigate the effect and potential molecular mechanism of PTGS2 on the prognosis of colon cancer patients.Methods The transcriptomic and proteomic data of pan-cancer were collected from TCGA,HPA,UALCAN and other databases,and the expression pattern and prognostic value of PTGS2 were analyzed by combining the clinical data such as staging,histology,survival time and so on.Based on GSEA,the biological functions which were significantly activated in patients with high expression of PTGS2 were iden-tified and the colon cancer cell line SW480 was used as an example for in vitro validation.PTGS2 over-expressing cell strains were constructed,and the effect on cell proliferation was determined by CCK8 method.Different concen-trations of H2O2 were used to form gradient oxidative stress,and the changes in cell antioxidant capacity were detected.The regulatory mechanism was preliminarily verified by Western blot.Results The transcription and expression of PTGS2 were found to be significantly up-regulated in colon cancer patients(P<0.05),and the increased expression of PTGS2 was associated with an increased mortality risk(P<0.05).Data analysis and in vitro experiments showed that over-expression of PTGS2 may promote the proliferation of colon cancer cells by activating the mTOR pathway.The antioxidant effect of cells was regulated by up-regulating oxidative stress regulatory proteins SOD2 and NRF2.Conclusions PTGS2 is a potential risk factor for colon cancer and its over-expression promotes cell proliferation,enhances cell antioxidant effect and is associated with poor progno-sis of colon cancer patients.
