Neonatal diabetes mellitus （NDM） is a rare monogenic disorder primarily caused by insufficient insulin secretion resulting from mutations in the KCNJ11 and ABCC8 genes. Sulfonylureas， represented by glibenclamide， have become the standard therapy for this type of NDM by precisely closing the mutated ATP-sensitive potassium channels in pancreatic β cells， thereby restoring insulin secretion. Clinical studies confirm that sulfonylureas enable over 90% of patients to successfully transition from insulin to oral treatment， achieving long-term stable glycemic control and improving neurological outcomes to a certain extent. In terms of safety， severe hypoglycemia induced by sulfonylureas is relatively rare and gastrointestinal reactions are mild； moreover， sulfonylureas show good long-term tolerability， and have no adverse effects on child growth and development. In the future， by further refining the full-chain management pathway of “rapid genetic diagnosis-early intervention-specialized dosage forms-long-term follow-up”， the clinical application of sulfonylureas is expected to provide NDM patients with an optimized treatment regimen and maximize their health benefits.

Anti-CD20 monoclonal antibodies for the treatment of refractory nephrotic syndrome （RNS） in children. The first- generation rituximab is the most widely used in clinical practice； it shows definite efficacy in children with RNS， is recommended by guidelines， particularly for achieving a high remission rate in minimal change nephrosis， and can significantly reduce the cumulative use of glucocorticoids and immunosuppressants. The second-generation ofatumumab has potential as an alternative treatment for patients who are intolerant or resistant to rituximab， while the third-generation obinutuzumab has shown efficacy in complex cases such as rituximab resistance or post-transplant recurrence. However， there is still controversy regarding the optimization of rituximab treatment dosage and whether ofatumumab and obinutuzumab offer greater advantages than rituximab for the treatment of RNS in children. The most common adverse reaction induced by anti-CD20 monoclonal antibodies is infusion reactions， and long-term adverse events mainly include increased risks of sustained immunosuppression and infections. Rituximab has significant economic advantages for the treatment of RNS， but additional pharmacoeconomic research based on China’s healthcare environment is needed to evaluate the cost-effectiveness of ofatumumab and obinutuzumab in this population. Given that the current use of ofatumumab and obinutuzumab in this field is considered off-label use， clinical application should only proceed after a rigorous evaluation of the patient’s benefits and risks.

Organoids are three-dimensional (3D) cellular structures formed through the differentiation and self-organization of pluripotent stem cells or tissue-derived cells, showing considerable potential in the research on disease mechanism, personalized medicine, and developmental biology. However, the development of organoids is limited by the complex composition, batch-to-batch variations, and immunogenicity of basement-membrane matrix in the current culture system, which hinders the clinical translation and in vivo applications of organoids. Hydrogels are highly hydrated 3D polymer network materials, with modifiable mechanical and biochemical properties by engineering, representing an ideal alternative to basement-membrane matrix. This article reviews the research progress in engineered hydrogels with defined composition currently used in organoid culture. We introduce the structural characteristics and engineering design considerations of hydrogels, emphasize the latest research progress and specific application cases, and discuss the future development of these engineered hydrogels, provide valuable insights for the further advancement and optimization of engineered hydrogels for organoid.

Objective:To explore the effectiveness of find-organize-clarify-understand- select-plan-do-check-act (FOCUS-PDCA) cycle management in improving the accuracy of Nutritional Risk Screening 2002 (NRS 2002) scoring in inpatients.Methods:This study was a retrospective study. Data from a continuous quality improvement project, namely Improving the Accuracy of Nutritional Risk Screening for Inpatients from People's Hospital of Longhua in 2021 were selected. The NRS 2002 scores of newly admitted patients from 8 departments with relatively high nutritional risk (departments of gstroenterology, neurology, nephrology, respiratory medicine, oncology and hematology, neurosurgery, gastrointestinal surgery, and critical care medicine) from April 10, 2021 to April 29, 2021 (before intervention) were collected. The NRS 2002 scores were evaluated by a multidisciplinary nutrition support team in terms of accuracy and error types. Possible issues in the process of nutritional screening were analyzed and mitigated using the FOCUS-PDCA cycle management method. The NRS 2002 scores from July 18, 2021 to August 8, 2021 (after intervention) were collected in real time to summary the data on accuracy and error types and to evaluate the effect of FOCUS-PDCA.Results:The accuracy of NRS 2002 score in the 8 departments was increased from 52.97% (294/555) to 81.13% (473/583) after intervention, and the difference was statistically significant ( χ2=102.606, P<0.001). The accuracy of nutritional status impairment score was 64.14% before intervention, compared with 90.57% after intervention ( χ2=114.484, P<0.001). The accuracy of disease severity score was 78.56%, compared with 89.54% after intervention( χ2=25.736, P<0.001). The false-negative rate was 68.02% before intervention and 31.87% after intervention, and the difference was statistically significant ( χ2=31.501, P<0.001). Conclusion:FOCUS-PDCA can improve the accuracy of NRS 2002 scoring in inpatients, reduce the risk of failing to identify patients at nutritional risk, and contribute to further nutritional diagnosis and treatment.

Objective To evaluate the left ventricular systolic function of patients with type 2 diabetes mellitus(T2DM)combined with renal insufficiency(CKD)by applying automated myocardial motion quantifica-tion(aCMQ)and to investigate its correlation with clinical biochemical indexes.Methods 80 patients with T2DM were enrolled,divided into DM group(without CKD,n=40)and DN group(with CKD,n=40),and 40 healthy volunteers were selected as the control group.The general clinical data of all subjects were recorded,and routine echocardiography and aCMQ were performed to obtain routine ultrasonographic measurements and aCMQ-related parameters.Results Comparison of aCMQ-related parameters:The differences in LV global longitudinal strain(LVGLS),LV apical 2-chamber longitudinal strain(LVAP2LS),LV apical 3-chamber longitudinal strain(LVAP3LS),and LV apical 4-chamber longitudinal strain(LVAP4LS)among the three groups were all statistically significant(P<0.05).The differences in LV global circumferential strain(LVGCS)between the DN group and the other two groups were statistically significant(P<0.05).The differences in LV short-axis basal segment cyclic strain(LVSAXBCS),LV short-axis middle segment cyclic strain(LVSAXMCS),and LV short-axis apical segment cyclic strain(LVSAXACS)were not statistically significant(P>0.05).LV strain was negatively correlated with Hs-CRP,GA,HbA1c,creatinine,urea,and uric acid,and positively correlated with eGFR.Correlation.High-sensitivity C-reactive protein(Hs-CRP),glycated albumin(GA)and eGFR showed good correlation with LV strain parameters.Conclusion The aCMQ technique can detect the deterioration of left ventricular function in patients with type 2 diabetes mellitus combined with renal insufficiency at an early stage,and the correlation between left ventricular strain parameters and hs-CRP,GA and eGFR can help to better assess their cardiac involvement.
