Tumors exhibit abnormal glucose metabolism, consuming excessive glucose and excreting lactate, which constructs a tumor microenvironment that facilitates cancer progression and disrupts immunotherapeutic efficacy. Currently, tumor glucose metabolic dysregulation to reshape the immunosuppressive microenvironment and enhance immunotherapy efficacy is emerging as an innovative therapeutic strategy. However, glucose metabolism modulators lack specificity and still face significant challenges in overcoming tumor delivery barriers, microenvironmental complexity, and metabolic heterogeneity, resulting in poor clinical benefit. Nanomedicines, with their ability to selectively target tumors or immune cells, respond to the tumor microenvironment, co-deliver multiple drugs, and facilitate combinatorial therapies, hold significant promise for enhancing immunotherapy through tumor glucose metabolic reprogramming. This review explores the complex interactions between tumor glucose metabolism-specifically metabolite transport, glycolysis processes, and lactate-and the immune microenvironment. We summarize how nanomedicine-mediated reprogramming of tumor glucose metabolism can enhance immunotherapy efficacy and outline the prospects and challenges in this field.

Objective:To explore the value of the "sandwich" feedback method based on the PDCA (plan, do, check, action) cycle in improving the ability of faculty in the department of radiology in teaching clinical radiological image interpretation during standardized residency training.Methods:The study involved six faculty members engaged in standardized residency training in the department of radiology from January 2023 to January 2024. The "sandwich" feedback method based on PDCA cycle was adopted to improve their ability in teaching clinical radiological image interpretation quarterly. The teaching ability was evaluated by residents and peer faculty members. A survey on teaching satisfaction was carried out.Results:Comparison of the teaching ability between PDCA cycles demonstrated a progressive increase in scores as rated by both residents and peer faculty members (scores from quarter 1 to quarter 4 were (77.00±2.53)/(80.33±3.26), (79.16±2.04)/(82.83±2.86), (81.83±1.17)/(85.16±1.17), (83.00±1.41)/(86.00±1.41). ANOVA of repeated measures indicated that quarter had a significant impact on both peer faculty member and resident evaluations ( P<0.001), and the results remained significant after Greenhouse-Geisser correction (G-G) and Huynh-Feldt correction (H-F). Moreover, a steady increase was observed in the scores of common deficiencies. The questionnaire survey showed that 88.88% (24/27) of the faculty members were "satisfied" or "very satisfied" with the feedback model. There were no significant differences in the scores of teaching feedback is necessary and aids in standardized teaching activities, creating an atmosphere before feedback is essential and effective "sandwich" feedback is helpful in improving the ability of faculty in teaching radiological image interpretation, and "sandwich" feedback can promote teaching reflection among faculty" between resident and peer faculty member evaluations ( P>0.05). Conclusions:The "sandwich" feedback method based on the PDCA cycle can effectively improve the ability of faculty in teaching clinical radiological image interpretation in the department of radiology and provide new ideas for achieving teaching homogeneity.

Objective:To explore the application of 1 565 nm non-ablative fractional laser in the treatment of enlarged facial pores.Methods:It was a longitudinal cohort study. From September 2020 to September 2021, 68 patients with enlarged facial pores, including 5 male patients and 63 female patients, aged between 20 and 41 (29.3±4.6) years, were treated at the Department of Plastic and Reconstructive Surgery of Ningbo Sixth Hospital. They received 1 565 nm non-ablative fractional laser once every month for a total of 3 times. The number, score and percentile ranking of facial pores before and after treatment were recorded and compared by VISIA, and adverse reactions were observed.Results:The facial pores number before and after treatment were 890.75±312.61 and 834.37±289.94, the facial pores score were 25.76±1.08 and 24.81±8.59, respectively, indicating a statistically significant decrease in facial pores number and score compared to before treatment ( t=4.19, 2.65, P<0.05). The facial pores percentile ranking before and after treatment were 4.00% (2.00%, 7.00%) and 5.00% (2.25%, 8.00%), respectively, indicating a statistically significant increase in facial pores percentile ranking compared to before treatment ( Z=-3.35, P<0.05). Three patients had transient pigmentation, all of which were gradually faded within 1 month after the last treatment. One patient had a few inflammatory papules scattered on the cheek, which faded in 3 days by using erythromycin eye cream. Conclusions:The 1 565 nm non-ablative laser can effectively improve enlarged facial pores with light adverse reactions.

Objective To explore how to achieve isolation of clinical trial fees and general medical expenses of hospitalized subjects through information technology.Methods This article analyzed various methods for separating clinical trials fees from medical insurance and suggested that all methods need to protect subjects'medical insurance reimbursement rights and ensure that they do not occupy medical insurance funds.Based on this principle,A clinical trial cost segregation information module was developed based on inpatient's workstation.Results Through this information module,subjects could choose their medical status according to the actual medical situation.Doctors could issue medical orders in hospital information system(HIS)according to normal medical or trail needs,change the nature of the orders by adding or deleting clinical trial tags.The system automatically intercepts the clinical trial orders for reimbursement of medical insurance,while other expenses are reimbursed according to rules of medical insurance.Conclusion The application of this information module has improved the subjects'enthusiasm and compliance to participate in clinical trials,reduced their economic burden,and ensured their rights to enjoy reimbursement of medical insurance,which can be used as a reference example for newly registered clinical trial institution.

Objective To observe the intervention effect of acupuncture at"Zusanli"(ST36)or"Neiguan"(PC6)on the ulcerative colitis(UC)model mice.And to analyze the similarities and differences of gene transcription expression between the diseased colon and the non-diseased heart after acupuncture intervention by using transcriptomics,to explore whether there are efficacy differences between the two acupoints.Methods The UC mouse model was established by inducing dextran sulfate sodium salt(DSS).After successful modeling,the mice were randomly divided into model group,Zusanli group,and Neiguan group,with 9 mice in each group.Zusanli group and Neiguan group intervened with acupuncture at"Zusanli"and"Neiguan",respectively,30 min each time,once a day,for 5 consecutive days.The control and model groups were only bound without acupuncture.Observe the general situation of mice in each group,calculate the disease activity index(DAI),observe the morphological changes of colon tissue by HE staining.Use transcriptome sequencing technology to sequence and biologically analyze the colon tissue of mice in each group,and compare and study whether the two acupoints have differences in acupoint efficacy from the perspective of diseased tissue.At the same time,take the heart tissues of each group for comparative analysis,and discuss whether the effects of the two acupoints are different from the perspective of non-diseased tissue.Results Compared with control group,the DAI score of the model group increased significantly(P<0.001),and HE staining results showed significant pathological damage;after acupuncture at Zusanli or Neiguan,the DAI scores of UC mice were reduced considerably(P<0.05),and the pathological damage was significantly improved.The results of transcriptome sequencing and bioinformatics analysis showed that the effects of acupuncture at Zusanli or Neiguan on the colon of diseased tissue involved multiple genes,and 825 differential genes with similar changes(co-DEGs)were mainly enriched in white blood cells and chemokine pathways;there were 168 differentially expressed genes(ST36 only-DEGs)affected only by Zusanli,which were enriched to gastric acid secretion and other pathways;there were 325 differentially expressed genes(PC6 only-DEGs)only affected by Neiguan,which were enriched in cytokine-cytokine receptor interaction and other pathways.There were 95 co-DEGs in the heart of non-diseased tissue,which were mainly enriched in positive regulation of defense response and response to interleukin-1;there were 28 ST36 only-DEGs;there were114 PC6 only-DEGs,which were enriched in cardiovascular diseases and other pathways.Conclusion Acupuncture of"Zusanli"and"Neiguan"could improve UC mice's symptoms and pathological colon changes.However,through transcriptomic analysis,it was found that the two acupoints had differences in gene transcription effects on the colon of diseased tissue and the heart of non-diseased tissue,suggesting that acupoints with different distribution positions had some similarities in macro efficacy.Still,there were some differences at a micro level.

Objectives:To evaluate the efficacy and safety of adalimumab (ADA) biosimilar in the treatment of Crohn′s disease (CD) .Methods:A retrospective cohort study was conducted. The patients with CD treated with ADA biosimilar in the Sixth Affiliated Hospital of Sun Yat-sen University from January 2019 to March 2022 with complete data were enrolled. The disease activity of patients at baseline was evaluated by Harvey-Bradshaw index (HBI) . The patients were divided into active group and remission group according to the activity. The primary endpoints were clinical response rate and remission rate at the 12th week in patients with active CD. The secondary endpoints included the clinical response rate and the remission rate in patients with active CD at the 26th week, maintenance remission rate at the 12th and the 26th weeks in patients with remission CD, and safety report.Results:Forty-eight patients were included. There were 20 patients whose HBI was 7 (6, 8) points in active group and 28 whose HBI was 3 (2, 4) points in remission group. In patients with active CD, the clinical response rate was 70.0% (14/20) and clinical remission rate was 60.0% (12/20) at the 12th week. The clinical response rate and clinical remission rate were both 61.5% (8/13) at the 26th week. The maintain remission rate of patients with remission CD was 96.4% (27/28) and 92.3% (12/13) at the 12th and the 26th weeks respectively. During the follow-up period, adverse reactions occurred in 2 patients (4.2%) and no serious adverse reaction was found.Conclusion:ADA biosimilar has good efficacy and safety in short-term induction and maintenance of clinical remission in Chinese patients with mild to moderate active CD.

Objective:To evaluate the efficacy, predictive factors, and safety of thalidomide monotherapy in the maintenance treatment of intestinal Behcet's disease.Methods:From January 2013 to March 2022, patients with intestinal Behcet's disease received thalidomide in the Sixth Affiliated Hospital of Sun Yat-sen University were retrospectively enrolled for analysis. The primary end points were the maintained steroid-free remission at 6 and 12 months. The secondary end points were the mucosal healing at 6 and 12 months, the long-term maintained steroid-free remission, predictive factors and adverse events.Results:A total of 28 patients with active intestinal Behcet's disease were enrolled. The maintained steroid-free remission at month 6, 12, 24 and 36 were 85.7%, 74.0%, 63.5% and 50.4% respectively. The median duration of maintained steroid-free remission was 49.5 (35.4, 63.6) months. Mucosal healing was 40.0% and 35.0% at month 6 and 12 respectively. Multivariate Cox regression analysis indicated that high disease activity index for intestinal Behcet's disease at baseline ( P = 0.014, HR = 1.057, 95% CI 1.011-1.104) was independently associated with lower likelihoods of maintaining steroid-free remission. During follow-up, 14 patients (50.0%) got adverse reactions and the incidence of limb numbness was 28.6%, with a median duration of 9.5 (5.5, 22.5) months. The drug dosage reduction rate was 14.3%, and the drug discontinuation rate was 17.9% due to side effects respectively. The median duration of drug discontinuation was 10.5 (23.5, 40.3) months. Conclusion:Thalidomide shows good effectiveness in maintaining long term steroid-free remission in intestinal Behcet′s disease, but the high incidence of limb numbness deserves attention.

Clinical undergraduates generally have the following problems during their radiology internship: short internship period, low motivation, teachers using traditional teaching mode, and insufficient hardware and software facilities for image reading. In this study, RadiAnt DICOM Viewer and case-based learning (CBL) model were applied in online practice teaching for clinical undergraduates in the radiology department, which achieved good results. The results showed that the clinical undergraduates had a pass rate of 91.18% (124/136) in the image reading quiz and a mean score of (85.71±10.99) in the in-class quiz, with a pass rate of 91.91% (125/136). The satisfaction survey showed that 84.56% (115/136) of the students were more satisfied with the application of RadiAnt DICOM Viewer in image reading teaching; 80.88% (110/136) of the students expressed more interest in radiology after this training course; 90.44% (123/136) of the students thought that online practice teaching of radiology is feasible.
