OBJECTIVE: To investigate the effect of zedoarondiol on neovascularization of atherosclerotic (AS) plaque by exosomes experiment. METHODS: ApoE^-/- mice were fed with high-fat diet to establish AS model and treated with high- and low-dose (10, 5 mg/kg daily) of zedoarondiol, respectively. After 14 weeks, the expressions of anti-angiogenic protein thrombospondin 1 (THBS-1) and its receptor CD36 in plaques, as well as platelet activation rate and exosome-derived miR-let-7a were detected. Then, zedoarondiol was used to intervene in platelets in vitro, and miR-let-7a was detected in platelet-derived exosomes (Pexo). Finally, human umbilical vein endothelial cells (HUVECs) were transfected with miR-let-7a mimics and treated with Pexo to observe the effect of miR-let-7a in Pexo on tube formation. RESULTS: Animal experiments showed that after treating with zedoarondiol, the neovascularization density in plaques of AS mice was significantly reduced, THBS-1 and CD36 increased, the platelet activation rate was markedly reduced, and the miR-let-7a level in Pexo was reduced (P<0.01). In vitro experiments, the platelet activation rate and miR-let-7a levels in Pexo were significantly reduced after zedoarondiol's intervention. Cell experiments showed that after Pexo's intervention, the tube length increased, and the transfection of miR-let-7a minics further increased the tube length of cells, while reducing the expressions of THBS-1 and CD36. CONCLUSION Zedoarondiol has the effect of inhibiting neovascularization within plaque in AS mice, and its mechanism may be potentially related to inhibiting platelet activation and reducing the Pexo-derived miRNA-let-7a level.

OBJECTIVES: Verrucous epidermal nevus (VEN), seborrheic keratosis (SK), verruca plana (VP), verruca vulgaris (VV), and nevus sebaceous (NS) are common verrucous proliferative skin diseases with similar clinical appearances, often posing diagnostic challenges. Dermoscopy and reflectance confocal microscopy (RCM) can aid in their differentiation, yet their specific features under these tools have not been systematically described. This study aims to summarize and analyze the dermoscopic and RCM features of VEN, SK, VP, VV, and NS. METHODS: A total of 121 patients with histopathologically confirmed verrucous proliferative skin diseases were enrolled. Dermoscopy and RCM imaging was used to observe and analyze the microscopic features of these conditions. RESULTS: Under dermoscopy, the 5 diseases displayed distinct characteristics: VEN typically showed gyriform structures; SK was characterized by gyriform structures, comedo-like openings, and milia-like cysts; VP and VV featured dotted vessels and frogspawn-like structures; NS presented as brownish-yellow globules. RCM revealed shared features such as hyperkeratosis and acanthosis across all 5 diseases. Specific features included gyriform structures and elongated rete ridges in VEN; pseudocysts and gyriform structures in SK; evenly distributed ring-like structures in VP; vacuolated cells and papillomatous proliferation in VV; and frogspawn-like structures in NS. CONCLUSIONS These 5 verrucous proliferative skin conditions exhibit distinguishable features under both dermoscopy and RCM. The combination of these 2 noninvasive imaging modalities holds significant clinical value for the differential diagnosis of verrucous proliferative skin diseases.

OBJECTIVE: Psoriasis, a common chronic inflammatory skin condition with genetic underpinnings, is traditionally managed with cupping therapy. Although used historically, the precise mechanical effects and therapeutic mechanisms of cupping in psoriasis remain largely unexamined. This study aimed to evaluate cupping therapy's efficacy for psoriasis and investigate its role in modulating inflammatory responses and cellular metabolism. METHODS: Psoriasis was induced in mice using topical imiquimod (IMQ). The effects of cupping on psoriatic lesions were assessed using the Psoriasis Area and Severity Index score, histology, immunohistochemistry, and immunofluorescence staining. polymerase chain reaction sequencing (RNA-seq) and Western blotting were conducted to examine changes in mRNA expression and the AMP-activated protein kinase (AMPK) signaling pathway. RESULTS: Cupping therapy significantly reduced inflammation, epidermal thickness, and inflammatory cell infiltration in mice with IMQ-induced psoriasis. Immunohistochemistry and immunofluorescence showed lower expression of inflammatory markers and a shift in T-cell populations. RNA-seq and Western blotting indicated that cupping upregulated Piezo1 and activated the AMPK pathway, improving energy metabolism in psoriatic skin. CONCLUSION Cupping therapy reduces epidermal hyperproliferation and inflammation in psoriasis, rebalancing the local immune microenvironment. Mechanistically, cupping promotes calcium influx via Piezo1, activates AMPK signaling, and supports metabolic homeostasis, suggesting therapeutic potential for psoriasis.

Based on the Political Economic Social Technological(PEST)-Strengths Weakness Opportunity Threats(SWOT)model,by sorting out the macro-environmental factors such as politics,economy,society and technology,and combining the internal strengths and weaknesses of the hospital as well as the external opportunities and threats,it puts forward the strategies to optimize the comprehensive budget management.It is found that hospitals face problems in total budget management such as disconnection between budgeting and strategy,and low level of informatization,but they also have advantages such as resource optimization and support for decision-making.The external environment provides opportunities such as health insurance reform and financing channel expansion,while there are threats such as industry competition and data security.It is suggested to improve the budget management level and promote the high-quality development of hospitals by expanding funding sources,strengthening cost control,and promoting the integration of industry and finance.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

The aim of this research was to investigate the mechanism of chelidonine on H2 O2-in-duced inflammatory injury in porcine intestinal epithelial cells(IPEC-J2)through transcriptome sequencing.IPEC-J2 cells in the logarithmic growth phase were divided into the blank group(K group),H2O2 group(S group)and chelidonine group(L group),with three replicates in each group.Total RNA was isolated from each group for the purpose of constructing a sequencing li-brary.The assembled data underwent functional annotation,differential gene analysis,as well as GO and KEGG enrichment analyses.qPCR was used to confirm the expression of key differentially expressed genes(DEGs),and ELISA was utilized to assess the effect of chelidonine on the permea-bility of IPEC-J2 cells.The results indicated that the sequencing data met the necessary criteria and demonstrated a strong correlation between samples.The GO functional annotation results suggest that the intervention effects of chelidonine involve biological processes such as oxidative stress re-sponse and G2/M phase transition regulation of the mitotic cycle,and are closely associated with molecular functions,such as transmembrane transport activity.The KEGG enrichment analysis indicates that following H2 O2 treatment,DEGs in IPEC-J2 cells are predominantly enriched in the p53 signaling pathway,the coagulation cascade,the FoxO signaling pathway,and various other sig-naling pathways.Following pretreatment with chelidonine,the DEGs exhibit significant enrichment in several signaling pathways related to inflammation,including the TNF signaling pathway,syn-aptic vesicle cycle,and IL-17 signaling pathway.The results of qPCR were consistent with the se-quencing results.Chelidonine has also been found to effectively inhibit LDH release,elevate GLN content,and decrease DOA content.In conclusion,it can be seen that chelidonine can reduce cell permeability and alleviate H2 O2-induced inflammatory injury in IPEC-J2 cells by modulating in-flammation-related pathways such as the TNF signaling pathway.

Objective To study the correlation between the serum ferritin level and the pathological classification,tumor stage,PD-L1 expression,disease control rate(DCR),and survival period of patients with lung cancer.Methods A total of 85 patients with lung cancer admitted to our hospital from February 2020 to February 2021 were selected as the research subjects.All patients received immunotherapy,and the serum ferritin levels of patients before and after immunotherapy were detected.Meanwhile,according to the difference in serum ferritin levels before and after immunotherapy,the patients were divided into the increased group(31 cases)and the decreased group(54 cases).The correlation between the serum ferritin level and the pathological classification,tumor stage and PD-L1 expression level of patients was analyzed,and the DCRs and survival periods of patients with serum ferritin level≥300 ng/mL and<300 ng/mL before treatment were compared,as well as the increased group and the decreased group.The survival curve of patients in each group was analyzed by the Kaplan-Meier.Results Patients with tumor stage Ⅰ to Ⅲ showed significantly lower serum ferritin levels than patients with tumor stage Ⅳ(P<0.05).The DCR,3-year survival rate and progression-free survival(PFS)of patients with serum ferritin level≥300 ng/mL were significantly lower/shorter than those of patients with serum ferritin level<300 ng/mL(P<0.05).The DCR,3-year survival rate and PFS of patients in the increased group were significantly lower/shorter than those in the decreased group(P<0.05).Conclusion The increased serum ferritin level in lung cancer patients before treatment and the further increase after treatment are significantly associated with the reduced efficacy of immunotherapy and the shortened survival period.The combination of baseline serum ferritin levels before treatment and dynamic changes after treatment may serve as a clinical biomarker panel for predicting immunotherapy outcomes.

Sustainability is a critical issue in China's medical and health assistance and cooperation with Africa.As China enters a new phase in this field,achieving sustainability presents both opportunities and challenges.Summarizing past successes and identifying barriers are of great practical significance for future development.This study examines the current state of China's medical and health assistance and cooperation with Uganda and finds that China has actively sought to integrate into local communities by collaborating with Ugandan medical institutions.However,several factors continue to constrain the sustainability of these efforts,including Uganda's fragmented public-private healthcare system heavily reliant on external aid,the personnel structure of Chinese medical teams,and linguistic and cultural barriers between China and Uganda.Based on official policy documents from both countries and field research findings,this study recommends supporting and assisting Uganda in establishing an independent healthcare system,with a particular focus on maternal and child health,youth health,and chronic disease management.Furthermore,strengthening cultural exchanges can contribute to the sustainable development of China-Uganda and broader China-Africa medical and health assistance and cooperation.

Objective To evaluate the efficacy and safety of a novel intravascular lithotripsy(IVL)balloon—Vesscrack shockwave balloon—for vascular preparation before stent implantation in patients with severe coronary artery calcification(CAC).Methods This was a prospective,single-arm,multicenter study conducted in China from June 2022 to October 2022.Patients with severe CAC were treated with the Vesscrack shockwave balloon for lesion preparation,followed by drug-eluting stent(DES)implantation.Of these,33 patients underwent optical coherence tomography(OCT).The primary endpoint was procedural success,defined as successful stent implantation with residual stenosis≤30％and the absence of in-hospital major adverse events,including cardiac death,target vessel-related myocardial infarction,or target lesion revascularization.Results A total of 170 patients[mean age:(65.9±7.9)years,116 males]were enrolled.After treatment with IVL and DES,the minimum lumen diameter increased significantly compared to baseline[(2.34±0.40)mm vs.(0.95±0.33)mm,P＜0.001],the degree of stenosis was significantly reduced[(13.24±6.60)％vs.(65.18±10.59)％,P＜0.001].Procedural success was achieved in 100％of cases,and device success was 98.8％.The 30-day patient-related cardiovascular clinical composite endpoint(POCE)rate was 0.0,with no target lesion failure,no confirmed or potential thrombotic events were observed.The shockwave energy generator demonstrated excellent stability and ease of use.Among the 33 patients assessed with OCT,after IVL intervention,the maximum calcified area of the lumen[(3.51±1.51)mm2 vs.(2.85±1.80)mm2,P＜0.001],and the minimum lumen area within the target lesion[(3.08±1.04)mm2 vs.(2.02±0.75)mm2,P＜0.001],and after DES intervention,the luminal area of the largest calcified site[(6.59±1.64)mm2 vs.(2.85±1.80)mm2,P＜0.001]and the minimum luminal area within the target lesion[(6.19±1.45)mm2 vs.(2.02±0.75)mm2,P＜0.001]were significantly increased,and the differences were statistically significant.Conclusions The Vesscrack shockwave balloon is effective and safe for vascular preparation in patients with severe CAC prior to stent implantation.It achieves significant calcified plaque modification,high procedural success rates,and minimal complications.

Objective To evaluate the efficacy of the manual cyclotorsion compensation method based on the obser-vation screen in the correction of with-the-rule astigmatism during small incision lenticule extraction(SMILE).Methods This prospective study enrolled 40 patients who underwent SMILE and another 40 patients who underwent Q-value-guided femtosecond laser-assisted laser in situ keratomileusis(FS-LASIK)at the Ophthalmology Center of the Second Affiliated Hospital of Nanchang University from April to September 2024.Through the random number method,one eye of each pa-tient who underwent SMILE was assigned to the manual cyclotorsion compensation group(the cyclotorsion group,40 eyes),while the contralateral eye was assigned to the non-cyclotorsion group(the non-cyclotorsion group,40 eyes).Meanwhile,one eye of each patient who underwent FS-LASIK was randomly selected for the FS-LASIK group(40 eyes).The age,uncorrected distance visual acuity(UDVA),spherical power,cylindrical power,spherical equivalent(SE),and corrected distance visual acuity(CDVA)were recorded before surgery and 3 months after surgery,respectively.Astigma-tism was subjected to Alpins vector analysis,and the indicators for assessing astigmatism included target-induced astigma-tism(TIA),surgically-induced astigmatism(SIA),difference vector(DV),correction index(CI),success index(IOS),angle of error(AE),and absolute value of angle of error(|AE|).Results Before surgery,there was no significant difference in age,spherical power,cylindrical power,SE,and CDVA among the cyclotorsion group,the non-cyclotorsion group,and the FS-LASIK group(all P＞0.05).At 3 months after surgery,the cyclotorsion group showed better UDVA and lower cylindrical power than the non-cyclotorsion group,with statistically significant differences(both P＜0.05);howev-er,there was no significant difference in CDVA,spherical power,and SE between the two groups(all P＞0.05).Besides,there was no significant difference in UDVA,CDVA,or refractive parameters between the cyclotorsion and FS-LASIK groups(all P＞0.05).The Alpins vector analysis of astigmatism 3 months after surgery revealed better SIA,CI,IOS,and|AE|in the cyclotorsion group compared with the non-cyclotorsion group,with statistically significant differences(all P＜0.05);however,there was no significant difference in TIA,DV,and AE between the two groups(all P＞0.05).No signifi-cant differences were found between the cyclotorsion and FS-LASIK groups in any astigmatism vector parameter(all P＞0.05).The linear regression analysis results indicated a high linear correlation between TIA and SIA in all groups.Conclu-sion The manual cyclotorsion compensation method based on the observation screen in the correction of with-the-rule astigmatism during SMILE is comparable to Q-value-guided FS-LASIK and superior to the conventional central tear film marking method in SMILE.
