Objective:To explore the clinical efficacy of chemoembolization with doxorubicin-infused gelatin sponge microparticles in the amelioration of arterioportal shunting (APS) in patients afflicted with hepatocellular carcinoma (HCC).Methods:A retrospective investigation was conducted on 9 HCC patients admitted between January 2020 and December 2022 with concomitant moderate-to-severe APS who underwent GSM-transarterial chemoembolization (TACE). Hepatic artery digital subtraction angiography (DSA) was employed to ascertain the magnitude of improvement in arteriovenous shunts, utilization of modified response evaluation criteria in solid tumors facilitated the appraisal of short-term clinical outcomes. Follow-up records documented survival duration, along with quantitative parameters such as the longest diameter of tumor lesions and serum alpha-fetoprotein (AFP) levels before and after treatment. The Wilcoxon rank-sum test was utilized to compare the differences of these quantitative parameters before and after treatment.Results:The APS amelioration rates were 100% and 88.9% at immediate and recent postoperatively, respectively. The oncological response rate was 77.8% (7/9), and the complete necrosis rate was 22.2% (2/9) at three months postoperatively, the 1-year survival rate was 100%. Following treatment, a significant reduction was observed in the tumor′s longitudinal diameter [4.32(3.88,6.63)cm] and serum AFP levels [13.50 (7.55, 29.60) μg/L], compared to the pre-treatment values of the tumor′s longitudinal diameter [5.20(4.58,8.57)cm] and serum AFP levels [524.30 (320.65, 1 046.15) μg/L] ( P<0.05 for all). Conclusion:Doxorubicin-infused GSM-TACE is both feasible and efficacious in the first treatment of HCC concomitant with APS and represents a better clinical alternative.

Periodontitis is the most widespread oral disease and is closely related to the oral microbiota. The oral microbiota is adversely affected by some pharmacologic treatments. Systemic antibiotics are widely used for infectious diseases but can lead to gut dysbiosis, causing negative effects on the human body. Whether systemic antibiotic-induced gut dysbiosis can affect the oral microbiota or even periodontitis has not yet been addressed. In this research, mice were exposed to drinking water containing a cocktail of four antibiotics to explore how systemic antibiotics affect microbiota pathogenicity and oral bone loss. The results demonstrated, for the first time, that gut dysbiosis caused by long-term use of antibiotics can disturb the oral microbiota and aggravate periodontitis. Moreover, the expression of cytokines related to Th17 was increased while transcription factors and cytokines related to Treg were decreased in the periodontal tissue. Fecal microbiota transplantation with normal mice feces restored the gut microbiota and barrier, decreased the pathogenicity of the oral microbiota, reversed the Th17/Treg imbalance in periodontal tissue, and alleviated alveolar bone loss. This study highlights the potential adverse effects of long-term systemic antibiotics-induced gut dysbiosis on the oral microbiota and periodontitis. A Th17/Treg imbalance might be related to this relationship. Importantly, these results reveal that the periodontal condition of patients should be assessed regularly when using systemic antibiotics in clinical practice.

OBJECTIVES:
To investigate the prevalence of pathogenic germline mutations of mismatch repair (MMR) genes in prostate cancer patients and its relationship with clinicopathological characteristics.
METHODS:
Germline sequencing data of 855 prostate cancer patients admitted in Fudan University Shanghai Cancer Center from 2018 to 2022 were retrospectively analyzed. The pathogenicity of mutations was assessed according to the American College of Medical Genetics and Genomics (ACMG) standard guideline, Clinvar and Intervar databases. The clinicopathological characteristics and responses to castration treatment were compared among patients with MMR gene mutation (MMR+ group), patients with DNA damage repair (DDR) gene germline pathogenic mutation without MMR gene (DDR+MMR- group) and patients without DDR gene germline pathogenic mutation (DDR- group).
RESULTS:
Thirteen (1.52%) MMR+ patients were identified in 855 prostate cancer patients, including 1 case with MLH1 gene mutation, 6 cases with MSH2 gene mutation, 4 cases with MSH6 gene mutation and 2 cases with PMS2 gene mutation. 105 (11.9%) patients were identified as DDR gene positive (except MMR gene), and 737 (86.2%) patients were DDR gene negative. Compared with DDR- group, MMR+ group had lower age of onset (P<0.05) and initial prostate-specific antigen (PSA) (P<0.01), while no significant differences were found between the two groups in Gleason score and TMN staging (both P>0.05). The median time to castration resistance was 8 months (95%CI: 6 months-not achieved), 16 months (95%CI: 12-32 months) and 24 months (95%CI: 21-27 months) for MMR+ group, DDR+MMR- group and DDR- group, respectively. The time to castration resistance in MMR+ group was significantly shorter than that in DDR+MMR- group and DDR- group (both P<0.01), while there was no significant difference between DDR+MMR- group and DDR- group (P>0.05).
CONCLUSIONS
MMR gene mutation testing is recommended for prostate cancer patients with early onset, low initial PSA, metastasis or early resistance to castration therapy.
