Objective To investigate the correlation between gut microbiota characteristics and immunotherapy efficacy in patients with advanced microsatellite stable (MSS) advanced gastrointestinal tumors. Methods Thirty patients with advanced MSS gastrointestinal tumors, including fourteen cases of gastric cancer and sixteen cases of colorectal cancer, who were admitted from November 1, 2022, to July 31, 2025 were enrolled. All patients underwent gut microbiota testing and received corresponding interventions on the basis of the results, followed by treatment with antiangiogenic agents combined with immunotherapy. Some patients additionally received probiotics or fecal microbiota transplantation. The primary endpoints were disease control rate (DCR) and objective response rate (ORR). The secondary endpoints were progression-free survival (PFS) and overall survival (OS). Univariate and multivariate Cox regression analyses were used to assess potential prognostic factors. Results Among the thirty patients, no complete response was observed. Two cases of partial response (PR), twelve cases of stable disease, and sixteen cases of progressive disease were recorded. The ORR was 6.7%, and the DCR was 46.7%. The median PFS was 6.4 months, and the median OS was 8.3 months. Both PR patients were classified as having a medium risk of gut microbiota dysbiosis and exhibited a Bacteroides-dominated enterotype. Multivariate analysis indicated that tumor type, liver metastasis, and bone metastasis were potential prognostic factors for PFS and OS. Conclusion Patients with a medium risk of gut dysbiosis may exhibit a relatively favorable response to immunotherapy, suggesting that gut microbiota status could serve as a potential biomarker for predicting treatment efficacy in advanced MSS gastrointestinal tumors.

Journal of Sun Yat-sen University(Medical Sciences) 2026;47(3):419-428
Chronic excessive alcohol consumption is a major global public health concern that severely endangers human health. Excessive alcohol intake disrupts the functions of multiple organs and systems in the human body through diverse mechanisms. The alcohol-sensitive microbiota-gut-brain axis plays a critical role in maintaining systemic homeostasis, immune maturation, and endocrine metabolism. Chronic excessive alcohol consumption not only alters the composition of the gut microbiota and the levels of its metabolites, but also compromises intestinal barrier integrity, increases intestinal permeability, and allows harmful metabolites to enter the systemic circulation, thereby triggering a variety of diseases including alcohol-related brain injury. Alcohol-related brain injury is one of the most severe consequences of unrecognized or inadequately treated alcohol use disorder (AUD), which can lead to extensive neuronal damage and neurocognitive dysfunction. Although the potential role of the microbiota-gut-brain axis in alcohol-related brain injury has been proposed, the exact underlying mechanisms have not yet been fully elucidated. Therefore, in this review, we systematically analyze the associations among chronic excessive alcohol consumption, the microbiota-gut-brain axis, and alcohol-related brain injury, and explore the potential mechanisms underlying alcohol-induced brain damage via this axis.

OBJECTIVE:
To evaluate the clinical significance of a hemizygous c.1042-10G>C variant of the SLC9A7 gene NM_001257291.2) previously identified in individuals with neurodevelopmental disorders, and to provide an evidence-based guidance for prenatal genetic counseling.
METHODS:
Four families presented at the Medical Genetics Center of Henan Provincial People's Hospital between December 2022 and July 2024 were included in this study. Phenotypic information and biological samples were collected from family members. Genomic DNA was extracted and subjected to whole-exome sequencing and copy number variation analysis to identify candidate pathogenic variants. Sanger sequencing was performed for familial co-segregation analysis. Reverse-transcription PCR was used to assess the RNA splicing pattern of the variant in peripheral blood samples. Quantitative PCR was employed to analyze the expression profiles of various SLC9A7 transcripts in fetal brain tissue and peripheral blood samples. Pathogenicity of the variant was classified based on guidelines from the American College of Medical Genetics and Genomics (ACMG). This study was approved by the Medical Ethics Committee of Henan Provincial People's Hospital (Ethics No.: 2021-171).
RESULTS:
Six hemizygous males carrying the SLC9A7 c.1042-10G>C variant were identified among the four families, which included three adult males and two male infants with normal phenotypes. Only one affected male from family 3 exhibited global developmental delay, short neck, webbed neck, ocular dysplasia, and congenital corneal leukoma. He also had a history of perinatal asphyxia and carried an additional hemizygous variant HUWE1 c.12283C>G. Reverse-transcription PCR showed no aberrant splicing in heterozygous or hemizygous carriers compared to healthy controls, suggesting that the variant does not affect RNA splicing. Quantitative PCR revealed that NM_001257291.2 is the predominant transcript expressed in fetal brain tissue and peripheral blood.
CONCLUSION
The SLC9A7 c.1042-10G>C variant does not alter RNA splicing and is present in multiple phenotypically normal males, which supported its classification as a benign variant.

OBJECTIVE:
To investigate the clinical phenotype and genetic characteristics of an infertile woman carrying a novel PADI6 gene variant.
METHODS:
An infertile woman who visited the Medical Genetics Center of Henan Provincial People's Hospital on April 29, 2024 was selected as the study subject. Clinical data of the proband and her family members were collected. Peripheral blood samples were obtained from the proband and her husband for genomic DNA extraction. Whole-exome sequencing (WES) was performed. Candidate variant was verified among the family members by Sanger sequencing. The pathogenicity of candidate variant was classified according to the American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Interpretation of Sequence Variants. Relevant literature on the pathogenic variants of the PADI6 gene was reviewed for genotype-phenotype correlation analysis. This study was approved by the Medical Ethics Committee of Henan Provincial People's Hospital (Ethics No.: 2021-171).
RESULTS:
The proband was a 35-year-old woman who underwent two oocyte retrieval cycles, yielding a total of five oocytes, with all embryos arrested at day 3 post-fertilization. WES identified a homozygous PADI6 variant, c.367+4_367+7del. In vitro splicing assay confirmed that this variant can cause skipping of exon 3, leading to a frameshift and alterations in the protein structure or premature termination of translation. Literature review identified 12 relevant publications, and the PADI6 c.367+4_367+7del was determined to be a novel variant.
CONCLUSION
The homozygous PADI6 c.367+4_367+7del variant probably underlay the pathogenesis of infertility in the proband.

Autism spectrum disorder(ASD) is a neurodevelopmental disorder, and social impairment was one of the core symptoms of ASD, which can seriously affects the social life of patients.The pathogenesis of social impairment in ASD is unclear and it may involves many brain abnormalities.The related theories and hypotheses are numerous and there is no unified conclusion. Studies have shown that the cerebellum has extensive connections with brain networks and is involved in the regulation of social cognition, but its role in ASD has not been fully emphasized.The structural and functional abnormalities of the cerebellar-cortex (CC) loop in ASD patients can lead to language communication disorders, empathy disorders, difficulties in interpreting social cues, abnormal social reward processing and emotional regulation disorders, which are closely related to ASD social impairment. Noninvasive brain stimulation of the superficial cerebellum can improve the abnormal CC circuit in ASD patients, and the cerebellum can be considered as a target for the treatment of social disorders in ASD in the future.Based on the clinical and basic researches on social impairment in ASD in recent years, this article reviews the relevant manifestations of disorders which cerebellar and CC circuit involved, aiming to promote the development of related research in the future.
