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 investigate the clinical characteristics,treatment methods,and prognosis of a-cute leukemia patients with extramedullary infiltration.Methods The clinical characteristics and treatment methods of 47 acute leukemia patients with extramedullary infiltration admitted to the Affiliated Hospital of Guizhou Medical University from April 2014 to April 2023 were retrospectively analyzed.Subgroup analysis was performed according to whether there was extramedullary infiltration before transplantation,and whether there was isolated extramedullary recurrence after transplantation.Based on this analysis,the patients were di-vided into the pre-transplantation radiotherapy group and pre-transplantation non-radiotherapy group,the post-transplantation radiotherapy group and post-transplantation non-radiotherapy group.According to the treatment methods of central nervous system leukemia(CNSL),the patients were divided into the intrathecal injection group(n=12)and combination of intrathecal injection and radiotherapy group(n=13).The local remission situation,survival duration,and toxic and side effects of radiotherapy and chemotherapy were com-pared.Results For acute leukemia patients with extramedullary infiltration,the overall survival time(OS)in the radiotherapy group was better than that in the non-radiotherapy group(median OS:706 d vs.151 d,P=0.015).Subgroup analysis showed that the OS of the pre-transplantation radiotherapy group was better than that of the pre-transplantation non-radiotherapy group(median OS:592 d vs.386 d,P=0.035).For CNSL,the combination of intrathecal injection and radiotherapy group had a better OS than the intrathecal injection group(median OS:547 d vs.388 d,P=0.045).The event-free survival time(EFS)of the radiotherapy group was better than that of the non-radiotherapy group(median EFS:175 d vs.50 d,P=0.005).The COX pro-portional-hazards model showed that treatment with or without radiotherapy had a significant impact on the OS of acute leukemia patients with extramedullary infiltration.The risk of death in the pre-transplantation non-radiotherapy group was 2.231 times higher than that in the pre-transplantation radiotherapy group(HR=3.231,95％CI:1.021-10.227,P=0.046).Compared with the non-radiotherapy group,the radiother-apy group had a higher local remission and a lower risk of haematological toxicity,infection,and haemorrhage.Conclusion Radiotherapy can rapidly alleviate the local symptoms of acute leukemia complicated with extr-amedullary infiltration,prolong the survival time of these patients,and reduce the risk of hematologic toxicity,infection,and haemorrhage.

AIM To explore the effects of Rosa roxburghii Radix on ulcerative colitis(UC)in rats based on pyroptosis and neutrophil extracellular traps(NETs).METHODS Rats were randomly divided into the normal group and the model group.The successfully established UC rat models by trinitrobenzene sulfonic acid(TNBS)/ethanol enema were then randomly divided into the model group,the sulfasalazine group(0.3 g/kg)and the low,medium and high dose R.roxburghii Radix groups(2,4,8 g/kg),followed by dosing of corresponding drugs by gavage.21 days later,the rats had their disease activity index(DAI)score calculated;their pathological changes of colon tissue observed by HE staining;their levels of serum interleukin(IL)-18,IL-1β and myeloperoxidase(MPO)detected by ELISA;and their protein expressions of NE,MPO,NLRP3,caspase-1 and GSDMD in colon tissue detected by Western blot and immunohistochemistry.RESULTS Compared with the normal group,the model group displayed increased DAI score(P＜0.01),increased serum levels of IL-1β,IL-18 and MPO(P＜0.01),and increased protein expressions of NE,MPO,caspase-1,NLRP3 and GSDMD in colon tissue(P＜0.01).Compared with the model group,the groups intervened with sulfasalazine,or medium,or high dose R.roxburghii Radix demonstrated with decreased DAI scores(P＜0.05,P＜0.01),decreased serum levels of IL-1β,IL-18 and MPO(P＜0.01),and decreased protein expressions of NE,MPO,caspase-1,NLRP3 and GSDMD in colon tissue(P＜0.05,P＜0.01).CONCLUSION R.roxburghii Radix may alleviate the inflammatory reaction in a rat model of UC and improve its pathological injury of colon via regulating pyroptosis and NETs.

Objective To investigate the preventive effect of schisandrin(SCH)on fetal neural tube defects(NTDs)of mice and its mechanism.Methods C57BL/6 mice were mated with female and male at a ratio of 2:1.Pregnant female mice with vaginal plug after mating were randomly divided into control group,model group,SCH group,and folic acid group,with 9 mice in each group.The NTDs fetal mice model was induced by intraperitoneal injection of all-trans retinoic acid(atRA)(7.5 mg/kg)on embryonic day 7.5(E 7.5 d).During E 0.5 d-E 11.5 d,pregnant rats in folic acid group were given folic acid[61.0 μg/(kg·d)]by gavage once a day,and pregnant rats in SCH group were given SCH[8.0 mg/(kg·d)]by gavage once a day.Fetal mice were removed by cesarean section on E 11.5 d.PC12 cells were divided into control group,model group and SCH group.PC12 cells were treated with atRA(20 μmol/L)for 12 hours to establish cell damage model in model group,and treated with SCH(2.5 μmol/L)for 24 hours in SCH group.Fetuses were identified NTDs by stereoscopic microscopy.HE staining was used to observe the closure of the neural tube.The expression levels of p-PI3K,Akt and p-Akt molecules in PI3K/Akt signaling pathway were detected by Western Blotting.Results Compared with control group,the incidence of NTDs was significantly increased in mice of model group(P<0.01);compared with model group,the incidence of NTDs was decreased in folic acid group and SCH group(P<0.01);compared with folic acid group,SCH group had a lower incidence of NTDs(P<0.01).Western Blotting results showed that compared with control group,the expression of p-PI3K and p-Akt protein in fetal tissues of model group was significantly decreased(P<0.01,P<0.05);compared with model group,there was no significant difference in expression of p-PI3K and p-Akt in fetal tissues of folic acid group(P>0.05),while the expression of p-PI3K and p-Akt protein in SCH group was significantly higher(P<0.05).Compared with control group,PC12 cells in model group showed lower expression levels of p-PI3K and p-Akt(P<0.05);compared with model group,PC12 cells in SCH group showed higher expression levels of p-PI3K and p-Akt(P<0.05).Conclusions SCH can reduce the incidence of atRA-induced NTDs in fetal mice,and its preventive effect is better than folic acid,which may be related to the activation of the PI3K/Akt signaling pathway.

ABO blood groups have been associated to increased susceptibility in allergic diseases, including asthma and atopic dermatitis. Although few studies demonstrated the association of ABO blood groups with allergic rhinitis, the evidences are still generally scarce and involved certain population. Therefore, this study aimed to investigate the association of ABO blood groups and allergic rhinitis in the Malaysian population. Further analysis was conducted to investigate the association between ABO blood groups and specific allergens, such as house dust mites, in patients with allergic rhinitis. A total of 163 patients with allergic rhinitis and 163 controls were recruited from AMDI, USM, Penang and HUSM, Kelantan. Blood samples were collected from both groups, and ABO phenotypes were identified using the tube method. The Pearson Chi-square test was employed to determine the association. Statistical significance was set for an alpha error of 5% (p-value < 0.05). O blood was identified as the most common blood group. However, no significant associations of ABO blood groups were observed in the allergic rhinitis patients. The result was also not significant with the O blood group being the highest prevalence and the AB blood group being the least prevalence to house dust mites allergy. This study provides beneficial information for future studies on the predictive role of blood groups in clinical practices. In our study, most of the participants recruited were Malays which might cause genetic bias. Therefore, employing a multi-centered and multiracial approach with larger sample size is recommended for future research.

Objective:To observe the effect of Tongxie Yaofang on the expressions of colon serotonin transporter （SERT）， liver 5-hydroxytryptamine_2A receptor （5-HT_2AR） protein， serum 5-HT and inflammatory factors in ulcerative colitis （UC） model rats of liver stagnation and spleen deficiency， in order to explore the basis of syndrome of liver stagnation and spleen deficiency and the intervention mechanism of Tongxie Yaofang. Method:Fifty male SD rats were randomly divided into blank control group， model group， high， medium and low-dose Tongxie Yaofang group （10，5，2.5 g·kg^-1）， and salazosulacil group （0.3 g·kg^-1）. The ulcerative colitis model of liver depression and spleen deficiency was established by 2，4，6-trinitrobenzene sulfonic acid （TNBS）/ethanol solution enema + restraint stress + diet loss. After successful modeling， the samples were collected after 21 days of drug intervention. Htoxylin eosin （HE） staining and oil red staining were used to observe the pathological changes of colon and liver in each group. Serum interleukin-6 （IL-6）， IL-9， 5-HT and superoxide dismutase （SOD） were detected by enzyme linked immunosorbent assay （ELISA）. Protein expressions of SERT in the colons and 5-HT_2AR in liver of rats were detected by Western blot. Result:Compared with the normal group， obvious ulcers were formed in the colon and lipid droplets in the liver increased in the model group， serum levels of IL-6， IL-9 and 5-HT in the model group increased， while the level of SOD decreased （P<0.05）. The protein expression of SERT in colon decreased， whereas the protein expression of 5-HT_2AR in liver increased （P<0.05）. Compare with model group， the pathological damage of colon was improved， and the formation of lipid droplets in liver was reduced in high， medium-dose Tongxie Yaofang groups and sulfasalazine group. The serum levels of IL-6， IL-9 and 5-HT decreased， while the level of SOD increased in Tongxie Yaofang group and sulfasalazine group （P<0.05）. The protein expression of SERT in colon increased in high，low-dose Tongxie Yaofang groups and sulfasalazine group， and the protein expression of 5-HT_2AR in liver decreased in medium， low dose Tongxie Yaofang groups and sulfasalazine group （P<0.05）. Conclusion:Tongxie Yaofang may reduce the content of 5-HT， and regulate the intestinal motility and sensory system by up-regulating the expression of SERT in the colon， inhibit the expressions of IL-6，IL-9 and other inflammatory factors， and play an anti-inflammatory role， reduce the content of 5-HT and the expression of 5-HT_2AR in the liver， increase the level of SOD， regulate emotion and lipid metabolism in the liver， and then exert the intervention effect on ulcerative colitis with liver depression and spleen deficiency on the whole.

The paper aims to compare the protective effect of Salvia miltiorrhiza and Anemarrhena asphodeloides on AD cell model and investigate its protective mechanism by cell metabolomics platform. AD cell model was established by the abnormal phosphorylation of Tau protein in SH-SY5Y cells induced by okadaic acid. The protective effect of the extract of Salvia miltiorrhiza and Anemarrhena asphodeloides on the model was evaluated by cell proliferation-toxicity experiment. The metabolomics platform was used to study the efficacy of Salvia miltiorrhiza and Anemarrhena asphodeloides comprehensively, explore the potential biomarkers related to AD and the effect of drugs on the potential biomarkers. Salvia miltiorrhiza extract had a certain protective effect on the AD model (P < 0.05), while the Anemarrhena asphodeloides extract had no significant protective effect (P > 0.05). 45 significant differential metabolites and the related 12 metabolic pathways were identified using UHPLC-QTOF/MS platform, which were related to the AD cell model. After administration of Salvia miltiorrhiza extract, 30 different metabolites appeared callback, while after intervention of Anemarrhena asphodeloides extract, 7 metabolites appeared callback. The results showed that the extracts of Salvia miltiorrhiza and Anemarrhena asphodeloides had certain protective effects on the AD cell model with Tau protein abnormal phosphorylation, but Salvia miltiorrhiza had more extensive targets and could significantly improve the cell viability. The mechanism may be related to the regulation of the metabolic pathways of AD cell model induced by okadaic acid.

ABC transporters on the intestinal barrier, blood-brain barrier and on tumor cells will affect drug bioavailability, transport across the blood-brain barrier and multidrug resistance. The active ingredients of traditional Chinese medicines can affect the function and expression of ABC transporters. When combined with pharmaceuticals the potential interaction between the two can change the efficacy of the medicines. We review the ABC transporter superfamily and their distribution with regard to their relationship and interactions with traditional Chinese medicine on the intestinal barrier and the blood-brain barrier, as well as their role in tumor multidrug resistance mediated by ABC transporters. We summarize the research progress over the past five years.
