Pathological mechanism of immune disorders in diabetic kidney disease and intervention strategies

Diabetic kidney disease is one of the most severe chronic microvascular complications of diabetes and a primary cause of end-stage renal disease.Clinical studies have shown that renal inflammation is a key factor determining kidney damage during diabetes.With the development of immunological technology,many studies have shown that diabetic nephropathy is an immune complex disease,and that most patients have immune dysfunction.However,the immune response associated with diabetic nephropathy and autoimmune kidney disease,or caused by ischemia or infection with acute renal injury,is different,and has a complicated pathological mechanism.In this review,we discuss the pathogenesis of diabetic nephropathy in immune disorders and the intervention mechanism,to provide guidance and advice for early intervention and treatment of diabetic nephropathy.

Clarifying the relationship and analyzing the influential factors of bronchial asthma in children with attention-deficit hyperactivity disorder

BACKGROUND Bronchial asthma is closely related to the occurrence of attention-deficit hyperactivity disorder(ADHD)in children,which can easily have adverse effects on children’s learning and social interactions.Studies have shown that childhood asthma can increase the risk of ADHD and the core symptoms of ADHD.Compared with children with ADHD alone,children with asthma and ADHD are more likely to show high levels of hyperactivity,hyperactive-impulsive and other externalizing behaviors and anxiety in clinical practice and have more symptoms of somatization and emotional internalization.AIM To explore the relationship between ADHD in children and bronchial asthma and to analyze its influencing factors.METHODS This retrospective cohort study was conducted at Dongying People's Hospital from September 2018 to August 2023.Children diagnosed with ADHD at this hospital were selected as the ADHD group,while healthy children without ADHD who underwent physical examinations during the same period served as the control group.Clinical and parental data were collected for all participating children,and multivariate logistic regression analysis was employed to identify risk factors for comorbid asthma in children with ADHD.RESULTSSignificant differences were detected between the ADHD group and the control group in terms of family history ofasthma and allergic diseases, maternal complications during pregnancy, maternal use of asthma and allergymedications during pregnancy, maternal anxiety and depression during pregnancy, and parental relationshipstatus (P < 0.05). Out of the 183 children in the ADHD group, 25 had comorbid asthma, resulting in a comorbidityrate of 13.66% (25/183), compared to the comorbidity rate of 2.91% (16/549) among the 549 children in the controlgroup. The difference in the asthma comorbidity rate between the two groups was statistically significant (P <0.05). The results of the multivariate logistic regression analysis indicated that family history of asthma and allergicdiseases, maternal complications during pregnancy, maternal use of asthma and allergy medications duringpregnancy, maternal anxiety and depression during pregnancy, and parental relationship status are independentrisk factors increasing the risk of comorbid asthma in children with ADHD (P < 0.05).CONCLUSIONChildren with ADHD were more likely to have comorbid asthma than healthy control children were. A familyhistory of asthma, adverse maternal factors during pregnancy, and parental relationship status were identified asrisk factors influencing the comorbidity of asthma in children with ADHD. Clinically, targeted interventions basedon these factors can be implemented to reduce the risk of comorbid asthma.

Exposure to proton pump inhibitors and risk of diabetes:A systematic review and meta-analysis

BACKGROUND Exposure to proton pump inhibitors(PPIs)has been reported to have a potential role in the development of diabetes.AIM To determine the association between PPIs and diabetes.METHODS This meta-analysis is registered on PROSPERO(CRD42022352704).In August 2022,eligible studies were identified through a comprehensive literature search.In this study,odds ratios were combined with 95%confidence intervals using a random-effects model.The source of heterogeneity was assessed using sensitivity analysis and subgroup analysis.The publication bias was evaluated using Egger’s test and Begg’s test.RESULTS The meta-analysis included 9 studies with a total of 867185 participants.Results showed that the use of PPIs increased the risk of diabetes(odds ratio=1.23,95%confidence interval:1.05-1.43,n=9,I2=96.3%).Subgroup analysis showed that geographic location and study type had significant effects on the overall results.Both Egger’s and Begg’s tests showed no publication bias(P>0.05).Sensitivity analysis also confirmed the stability of the results.CONCLUSION The results of this study indicated that the use of PPIs was related to an increased risk of diabetes.However,more well-designed studies are needed to verify these results in the future.

Small cell lung cancer starting with diabetes mellitus: Two case reports and literature review

BACKGROUND Small-cell lung cancer(SCLC)is a type of fatal tumor that is increasing in prevalence.While these are unpleasant facts to consider,it is vitally important to be informed,and it is important to catch the disease early.Typically,lung cancer does not show severe clinical symptoms in the early stage.Once lung cancer has progressed,patients might present with classical symptoms of respiratory system dysfunction.Thus,the prognosis of SCLC is closely related to the early diagnosis of the disease.Ectopic adrenocorticotropic hormone(ACTH)syndrome(EAS)is related to cancer occurrence,especially for SCLC with the presence of Cushing's syndrome,which is dependent on markedly elevated ACTH and cortisol levels.CASE SUMMARY In the current report,we describe two middle-age patients who were originally diagnosed with diabetes mellitus with no classical symptoms of lung cancer.The patients were eventually diagnosed with SCLC,which was confirmed by bronchoscopic biopsy and histopathology.SCLC-associated diabetes was related to EAS,which was an endogenous ACTH-dependent form of Cushing’s syndrome with elevated ACTH and cortisol levels.Multiple organ metastases were found in Patient 1,while Patient 2 retained good health at 2 years follow-up.EAS symptoms including thyroid dysfunction,hypercortisolism and glucose intolerance were all resolved after anticancer treatment.CONCLUSION In conclusion,SCLC might start with diabetes mellitus and increased cortisol and hypokalemia or other EAS symptoms.These complex clinical features were the most significant factors to deteriorate a patient’s condition.Early diagnosis and treatment from clinicians were essential for the anti-cancer treatment for patients with SCLC.

A New Method of Solving the Index Problem for Sturm-Liouville Eigenvalues

Based on some recent results for interlacing eigenvalue intervals from 1-parameter families of se- quences of eigenvalue inequalities, a new method is given to solving the index problem for Sturm-Liouville eigenvalues for coupled self-adjoint boundary conditions in the regular case. The key is a new characteristic principle for indices for Sturm-Liouville eigenvalues. The algorithm corresponding on the characteristic princi- ple are discussed, and numerical examples are presented to illustrate the theoretical results and show that the algorithm is valid.
