Research progress and advances in endoplasmic reticulum stress regulation of acute kidney injury.

Acute kidney injury (AKI) is a common and severe clinical disorder in which endoplasmic reticulum (ER) stress plays an important regulatory role. In this review, we summarize the research progress on the relationship between ER stress and AKI. It emphasizes the importance of maintaining a balance between promoting and protecting ER stress during AKI and highlights the potential of ER stress-targeted drugs as a new therapeutic approach for AKI.

Molecular mechanisms of endoplasmic reticulum stress-mediated acute kidney injury in juvenile rats and the protective role of mesencephalic astrocyte-derived neurotrophic factor.

Objectives: This study examined the role of endoplasmic reticulum stress in pediatric acute kidney injury and the therapeutic effect of midbrain astrocyte-derived neurotrophic factor.

Methods: Two-week-old Sprague-Dawley rats were divided into: Sham, ischemia-reperfusion injury-induced acute kidney injury (AKI), mesencephalic astrocyte-derived neurotrophic factor (MANF)-treated, tauroursodeoxycholic acid (TUDCA)-treated. Analyses were conducted 24 h post-treatment.

Using scalp EEG to predict seizure recurrence and electrical status epilepticus in children with idiopathic focal epilepsy.

Purpose: Some individuals with idiopathic focal epilepsy (IFE) experience recurring seizures accompanied by the evolution of electrical status epilepticus during sleep (ESES). Here, we aimed to develop a predictor for the early detection of seizure recurrence with ESES in children with IFE using resting state electroencephalogram (EEG) data.

Methods: The study group included 15 IFE patients who developed seizure recurrence with ESES.

Multiple mediation of the association between childhood emotional abuse and adult obesity by anxiety and bulimia - a sample from bariatric surgery candidates and healthy controls.

Bulimia, which means a person has episodes of eating a very large amount of food (bingeing) during which the person feels a loss of control over their eating, is the most primitive reason for being overweight and obese. The extended literature has indicated that childhood emotional abuse has a close relationship with adverse mood states, bulimia, and obesity. To comprehensively understand the potential links among these factors, we evaluated a multiple mediation model in which anxiety/depression and bulimia were mediators between childhood emotional abuse and body mass index (BMI).

Causal effect of age first had sexual intercourse and lifetime number of sexual partners on cervical cancer.

Objective: In this study, we aimed to investigate whether age first had sexual intercourse (AFSI) and lifetime number of sexual partners (LNSP) have a direct causal effect on cervical cancer by Mendelian randomization (MR) analysis.

Methods: Four approaches were used for MR Analysis, including MR-Egger, weighted method, weighted median, and inverse variance weighted (IVW). MR Pleiotropy RESidual Sum and Outlier (MR-PRESSO) as well as MR-Egger regression analysis were conducted to detect whether there was pleiotropy between IVs and outcome, and the outlier SNPs can be detected by MR-PRESSO.

Clinical Presentation and Genetic Analysis of Neonatal 11β-Hydroxylase Deficiency Induced by a Chimeric Gene.

In terms of prevalence, 11β-hydroxylase deficiency (11β-OHD), a common form of congenital adrenal hyperplasia, closely follows 21-hydroxylase deficiency. 11β-OHD has been attributed to diminished enzymatic activity owing to gene variants, mainly encompassing single nucleotide variations and insertions-deletions. The involvement of chimeric genes in 11β-OHD has rarely been reported.

A novel MAMLD1 variant in a newborn with hypospadias and elevated 17-hydroxyprogesterone.

Purpose: Disorders of sex development (DSD) have complex pathogenesis, and evidence suggests an association between MAMLD1 defects and DSD. MAMLD1 is expressed in gonadal tissues and affected males exhibit hypospadias, steroid hormone abnormalities, or gonadal underdevelopment. We performed genetic testing on a newborn patient with severe hypospadias and an elevation of 17-hydroxyprogesterone (17α-OH) for the diagnosis of DSD.

Identification of biomarkers, pathways, and therapeutic targets for EGFR-TKI resistance in NSCLC.

This study aimed to map the hub genes and potential pathways that might be involved in the molecular pathogenesis of EGFR-TKI resistance in NSCLC. We performed bioinformatics analysis to identify differentially expressed genes, their function, gene interactions, and pathway analysis between EGFR-TKI-sensitive and EGFR-TKI-resistant patient-derived xenotransplantation samples based on Gene Expression Omnibus database. Survival analysis was performed via the GEPIA database (GEO).

Diagnostic performance of type I hypersensitivity-specific markers combined with CRP and IL-6 in complicated acute appendicitis in pediatric patients.

Objective: In this study, the diagnostic value of C-reactive protein (CRP), interleukin-6 (IL)-6, and specific markers for type I hypersensitivity were evaluated in pediatric patients with severe acute appendicitis.

Methods: A total of 140 pediatric patients with "acute appendicitis" who underwent surgery at the Department of General Surgery of the Anhui Provincial Pediatric Patients' Hospital between December 2022 and April 2023 were studied retrospectively. The data collected included the gender, age, onset time, white blood cell count (WBC), CRP, procalcitonin (PCT), serum IgE, serum IL-4, serum IL-5, serum IL-6, serum IL-9, and serum IL-13 levels.

Activatable probes with potential for intraoperative tumor-specific fluorescence-imaging guided surgery.

Owing to societal development and aging population, the impact of cancer on human health and quality of life has increased. Early detection and surgical treatment are the most effective approaches for most cancer patients. As the scope of conventional tumor resection is determined by auxiliary examination and surgeon experience, there is often insufficient recognition of tiny tumors.

A Case of Ulcerative Colitis Induced by Paraneoplastic Syndrome?

Background: Paraneoplastic syndromes often cause endocrine, neurological, cutaneous, and hematologic pathologies, and cases with digestive symptoms as prominent cases are rare.

Case Description: A 1-year-old child admitted to the emergency department with severe abdominal distension was later diagnosed with sacrococcygeal yolk cystoma with ulcerative colitis. After symptomatic management, surgical removal of the tumor, and JEB chemotherapy, the symptoms of ulcerative colitis disappeared completely.

Analysis of type I hypersensitivity-induced inflammatory response in children of different age groups with acute appendicitis.

Objective: To explore the differences in type I hypersensitivity-induced inflammatory response among children of different age groups with acute appendicitis.

Methods: We selected children diagnosed with "acute appendicitis" who underwent surgery in the Department of General Surgery of Anhui Provincial Children's Hospital from January 2022 to June 2022 and collected their basic data. We divided them into two groups according to age: the infant group (less than 3 years old) and the pediatric group (3-14 years old).

Growth restriction and congenital heart disease caused by a novel mutation: A case report.

Congenital heart disease (CHD) is a malformation present from birth caused by the abnormal development of the heart and large blood vessels during the prenatal development. The TGF-β activated kinase 1 (MAP3K7) binding protein 2 (TAB2) gene plays an important role in the embryonic development of heart tissue. When haploid dosage is insufficient, it can lead to CHD or cardiomyopathy.

The functional change of the P2X7R containing the Ala to Thr polymorphism is associated with the pathogenesis of gout.

Our previous study has shown that ATP action on P2X7R could be the second signal to induce the onset of gouty arthritis. However, the functional changes of P2X7R single nucleotide polymorphisms (SNPs) on the effects of ATP-P2X7R-IL-1β signaling pathway and uric acid remained unknown. We aimed to investigate the association between the functional change of P2X7R containing the Ala to Thr polymorphisms (rs1718119) and the pathogenesis of gout.

Precision shaping of elastic stable intramedullary nail for the treatment of metaphyseal diaphysis junction fracture of the distal radius in children: a preliminary report in two centers.

Methods: Data about DRMDJs were collected from February 1, 2020, to April 31, 2022 at two hospitals, retrospectively. All patients were treated with closed reduction and ESIN-RPS fixation.

Tivantinib alleviates inflammatory diseases by directly targeting NLRP3.

NLRP3 inflammasome-mediated immune responses are involved in the pathogenesis of multiple inflammatory diseases, but few clinical drugs are identified that directly target the NLRP3 inflammasome to treat these diseases to date. Here, we show that the anticancer agent tivantinib is a selective inhibitor of NLRP3 and has a strong therapeutic effect on inflammasome-driven disease. Tivantinib specifically inhibits canonical and non-canonical NLRP3 inflammasome activation without affecting AIM2 and NLRC4 inflammasome activation.

Immune checkpoint inhibitors in advanced and recurrent/metastatic cervical cancer.

Cervical cancer (CC) poses a serious threat to women's health. Although many early-stage patients have a good prognosis, there are still a lack of effective therapies for advanced and recurrent/metastatic CC. In this context, immunotherapy and immune checkpoint inhibitors (ICIs) are particularly likely to play a role in the treatment of cervical tumors in a variety of disease settings.
