Introduction: The 2021 IDF-DAR risk calculator had been previously evaluated in multiple studies and subsequently widely accepted and applied in clinical practice as a practical standardized tool for patient risk stratification. Recently updated, the 2026 IDF-DAR Risk calculator enables a more individualized, evidence-related evaluation of patientrelated and disease-related risk factors, incorporating modern diabetes technologies, including continuous glucose monitoring (CGM), automated insulin delivery (AID) systems, and advanced insulin formulations to enhance risk stratification. This tool allows medical professionals to tailor Ramadan practices based on overall factors toward promoting safe fasting. Methodology: This prospective multicentre observational study recruited adults with Type 1 and Type 2 diabetes attending public hospitals nationwide. People with diabetes (PwD) intending to perform Ramadan fasting were invited to participate and assessed using the 2026 IDF-DAR Risk Calculator in the 6-week pre-Ramadan period between 30th January and 19th March 2026. Results: A total of 458 PwD were evaluated and stratified into low (15.7%), moderate (41%), and high risk (43.3%) categories. Most participants had Type 2 diabetes (83.6%), with 60.3% having a disease duration exceeding 10 years and 43% exhibiting poor glycemic control (hemoglobin A1c >9%). Insulin therapy was used by 76.4% of participants, including two individuals with Type 1 diabetes using AID systems. Most participants reported no recent hypoglycemia (76.4%), 81.0% performed glucose monitoring, and 3.3% used CGM. Severe comorbidities were uncommon, with 1.1% having unstable macrovascular disease and 4.4% advanced chronic kidney disease (estimated glomerular filtration rate <30). Notably, 72.2% received structured Ramadan education. Conclusion Majority of PwD attending tertiary diabetes clinics were in the moderate- to high-risk category and intended to fast despite medical advice against fasting in some cases. Although most participants were on insulin therapy, hypoglycemia was low in the pre-Ramadan period. Integration of modern technologies, advanced insulin therapies, and structured education may support safer fasting practices.

Objective:To construct a quality analysis model by combining the strengths-weaknesses-opportunities-threats(SWOT)analysis method and analytic hierarchy process(AHP),and to explore its application value in the quality management for operation of first aid equipment of hospital.Methods:The advantages,disadvantages,opportunities and threats of management for equipment were analyzed according to SWOT model,and the operation quality of equipment was positioning analyzed by AHP,and comprehensive management countermeasures were formulated from the aspects of personnel,system,preventive maintenance,information management and cooperation between institutes and enterprises.A total of 215 first aid equipment in clinical use in Qilu Hospital of Shandong University from January 2021 to December 2024 were selected.In these equipment,171 equipment from January 2021 to December 2022 were managed by using the conventional management mode,and 195 equipment(including 151 using equipment under the conventional management mode and 44 newly added equipment)from January 2023 to December 2024 were managed by using the strategic management mode with quality analysis model.The operation quality and management level of the two management modes for the equipment were compared.A self-made survey questionnaire was used to investigate the satisfaction scores of nurses of operating equipment,doctors of clinical department,medical engineers and administrators for the service effects of equipment under the two management modes,who use and manage the first aid equipment in hospital.Results:The average failure rate,risk rate,alarm rate and unqualified rate of first aid equipment in hospitals,which adopted the strategic management mode,were respectively(0.72±0.42)%,(1.08±0.70)%,(1.18±0.48)%and(1.33±0.63)%,all of which were lower than those of the conventional management mode,and the differences were statistically significant(t=3.629,2.792,2.179,2.396,P<0.05).The management level scores of monitors,ventilators,defibrillators,high-frequency electrosurgical knives and other first aid equipment,which adopted the strategic management mode,were respectively(94.69±1.68),(95.84±2.52),(95.38±2.85),(95.69±2.02)and(94.17±4.89)points,all of which were higher than those of the conventional management mode,and the differences were statistically significant(t=4.797,2.403,2.390,3.825,2.196,P<0.05).The satisfaction scores of nurses of operating equipment,doctors of clinical department,medical engineers and administrators for first aid equipment of adopting strategic management mode were all higher than those of adopting conventional management mode,and the difference were statistically significant(t=3.666,3.336,4.275,4.292,P<0.05).Conclusion:The quality analysis model of first aid equipment of hospital can improve the operation quality and management level of first aid equipment,and reduce the equipment's failure rate and the unqualified rate of quality inspection,and improve the service effect of first aid equipment.

Objective To evaluate the application value of the MR three-dimensional double inversion recovery(3D DIR)sequence in the diagnosis of optic neuritis(ON).Methods A retrospective analysis was conducted on MRI images from 40 patients with sus-pected ON.All patients underwent conventional T2 WI fat suppression(FS)and 3D DIR sequences.The lesion detection rate and diag-nostic accuracy of the intraorbital,intracanalicular,and intracranial segments of the optic nerve were compared between the two sequences,respectively.The receiver operating characteristic(ROC)curves were used to assess the diagnostic performance,and the intraclass correlation coefficient(ICC)were used to analyze interobserver consistency.Imaging assessments were independently performed by two senior and two junior radiologists.Results The sensitivity(SEN),specificity(SPE),and accuracy(ACC)in lesion detection of 3D DIR sequence were significantly better than those of conventional T2 WI FS sequence[odds ratio(OR)221 vs 104,P＜0.001].Notably,3D DIR sequence exhibited superior performance in detecting lesions in the intraorbital segment[area under the curve(AUC)0.915,OR=102]and intracanalicular segment(AUC 0.858,OR=51)compared with conventional T2WI FS sequence.Additionally,3D DIR sequence significantly improved diagnostic consistency among junior radiologists(ICC value increased from 0.469 to 0.655),bring-ing their diagnostic performance closer to that of senior radiologists(AUC improved to 0.883,ACC reached 90.1％).Conclusion The 3D DIR sequence has outstanding diagnostic efficacy in detecting ON lesions,significantly improving ACC and interobserver consistency,thereby offering strong support for the precise diagnosis of ON.

AIM To observe the effects of Yiqi Jiedu Tongluo Formula(YQJDTL)on renal microvascular endothelial function and prevention of renal injury in a rat model of type 2 diabetes mellitus(T2DM).METHODS The SD rats were randomly divided into a normal group and a model group.The model group was administered with high-fat diet combined with a single intraperitoneal injection of STZ to establish the T2DM model.The successfully modeled rats were randomly divided into the model group,the canagliflozin group(9 mg/kg),and the low-dose and high-dose YQJDTL groups(4.77,9.45 g/kg).The corresponding doses of the drug were administered by gavage for a total of 12 weeks,during which the rats underwent observation of their general condition and blood glucose changes.After the end of administration,the rats had their levels of renal index,24-hour UP,serum SCr,BUN,TC,TG,HDL-C,LDL-C,ET-1 and NOS measured;their changes in renal microvasculature and the degree of renal fibrosis observed using HE staining,Masson staining,PAS staining,and PASM staining;their ultrastructure of the glomeruli observed using transmission electron microscopy;their renal protein expressions of TGF-β,SMAD2,SMAD3,Col-1,VEGFA and PKC detected by immunohistochemical staining and Western blot;and their renal mRNA expressions of VEGFA,TGF-β,SMAD2 determined by RT-qPCR.RESULTS Compared with the model group,the high-dose YQJDTL group showed decreased levels of renal index,blood glucose,TG,TC,HDL,24 h UP,BUN,SCr and ET-1(P＜0.05,P＜0.01);increased LDL and NOS levels(P＜0.05,P＜0.01);reduced renal inflammatory infiltration and fibrosis degree,inhibited fusion of foot processes and thickening of basement membrane;decreased renal protein expressions of TGF-β,SMAD2,SMAD3,VEGFA,PKC and Col-1(P＜0.05,P＜0.01);and decreased mRNA expressions of VEGFA,TGF-β and SMAD2(P＜0.01).CONCLUSION In the rat models of T2DM,YQJDTL can reduce their levels of blood glucose and lipids by improving the renal indices levels and the renal microvascular endothelial functions to alleviate renal fibrosis and microangiopathy as well,and the mechanism may be associated with the down-regulated expressions of TGF-β/SMAD and VEGF pathway-related proteins.

Objective:To introduce the clinical application of "page-turning" superior pancreatic lymph node dissection in laparoscopic D2 radical gastrectomy for gastric cancer.Methods:Patients who were confirmed to have adenocarcinoma by preoperative gastroscopy and pathological biopsy, with tumor staging evaluated by imaging as cT1~4aN0~3M0, without neoadjuvant therapy, and without absolute surgical contraindications, underwent laparoscopic radical gastrectomy for gastric cancer with "page-turning" superior pancreatic lymph node dissection. The "page-turning" superior pancreatic lymph node dissection was performed in four steps: (1) Expose the posterior gastric mesentery and dissect No.11p lymph nodes; (2) Expose the left gastric mesentery and dissect No.7, No.8a and No.9 lymph nodes; (3) Expose the right gastric mesentery and dissect No.5 lymph nodes; (4) Expose the left edge of the portal vein and dissect No.12a lymph nodes.Results:From April 2018 to October 2024, 112 patients with gastric cancer underwent laparoscopic D2 radical gastrectomy with "page-turning" superior pancreatic lymph node dissection, including 21 cases in the First Affiliated Hospital of Guangzhou University of Chinese Medicine, 78 cases in the Second Affiliated Hospital of Guangzhou University of Chinese Medicine, and 13 cases in the Department of Gastrointestinal Surgery, Jilin Provincial People's Hospital. The TNM staging of all patients was as follows: 31 cases in stage Ⅰ, 24 cases in stage Ⅱ, and 57 cases in stage Ⅲ; 62 cases of differentiated adenocarcinoma and 50 cases of undifferentiated adenocarcinoma; the median length of tumors was 3.8 cm. All patients successfully completed the operation without conversion to open surgery, no intraoperative massive hemorrhage or postoperative death. The median total number of lymph nodes dissected in all patients was 32, and the median number of positive lymph nodes was 4.5. The overall postoperative complication rate was 5.4% (6/112), all of which were Clavien-Dindo grade Ⅱ, including pulmonary infection, pleural effusion, and incisional infection, all cured by symptomatic treatment. The median follow-up was 41.8 (2-78) months, with 7 cases lost to follow-up. During the follow-up period, 27 cases (25.7%) had tumor recurrence and 16 cases (15.2%) died.Conclusions:The "page-turning" superior pancreatic lymph node dissection technique is safe and feasible in laparoscopic radical gastrectomy for gastric cancer.

Objective:To investigate lymph node metastasis(LNM)in the prostatic anterior fat pad(PAFP)of PCa patients after robot-assisted radical prostatectomy(RARP),and analyze the clinicopathological features and prognosis of LNM in the PAFP.Methods:We retrospectively analyzed the clinicopathological data on 1 003 cases of PCa treated by RARP in the Department of Urolo-gy of PLA General Hospital from January 2017 to December 2022.All the patients underwent routine removal of the PAFP during RARP and pathological examination,with the results of all the specimens examined and reported by pathologists.Based on the pres-ence and locations of LNM,we grouped the patients for statistical analysis,compared the clinicopathological features between different groups using the Student's t,Mann-Whitney U and Chi-square tests,and conducted survival analyses using the Kaplan-Meier and Log-rank methods and survival curves generated by Rstudio.Results:Lymph nodes were detected in 77(7.7％)of the 1 003 PAFP samples,and LNM in 11(14.3％)of the 77 cases,with a positive rate of 1.1％(11/1 003).Of the 11 positive cases,9 were found in the upgraded pathological N stage,and the other 2 complicated by pelvic LNM.The patients with postoperative pathological stage≥T3 constituted a significantly higher proportion in the PAFP LNM than in the non-PAFP LNM group(81.8％[9/11]vs 36.2％[359/992],P=0.005),and so did the cases with Gleason score ≥8(87.5％[7/8]vs 35.5％[279/786],P=0.009).No statisti-cally significant differences were observed in the clinicopathological features and biochemical recurrence-free survival between the pa-tients with PAFP LNM only and those with pelvic LNM only.Conclusion:The PAFP is a potential route to LNM,and patients with LNM in the PAFP are characterized by poor pathological features.There is no statistically significant difference in biochemical recur-rence-free survival between the patients with PAFP LNM only and those with pelvic LNM only.Routine removal of the PAFP and inde-pendent pathological examination of the specimen during RARP is of great clinical significance.
