Objective To analyze the incidence and mortality of cancer in Ya'an City in 2022 and its trends from 2013 to 2022. Methods The crude and age-standardized cancer incidence and mortality rates (based on the Chinese standard population) were calculated by gender and age group from the Ya'an City registry data for 2022, and their trends from 2013 to 2022 were assessed using Joinpoint regression analysis. Results In 2022, the crude incidence rate of cancer in Ya'an City was 317.19/10⁵, and the age-standardized incidence rate was 178.45/10⁵. The crude mortality rate of cancer in Ya'an City was 185.10/10⁵, and the age-standardized mortality rate was 85.22/10⁵. The top three cancer types with the highest incidence were lung cancer, colorectal cancer, and female breast cancer, and those with the highest mortality were lung cancer, colorectal cancer, and liver cancer. From 2013 to 2022, the overall age-standardized incidence rate of cancer was relatively stable but showed a downward trend in males (P<0.05) and an upward trend in females (P<0.05). The overall age-standardized mortality rate exhibited a downward trend (P<0.05). The age-standardized incidence rate of thyroid cancer, prostate cancer, and lung cancer showed an upward trend (P<0.05), whereas those of liver cancer, gastric cancer, and esophageal cancer showed a downward trend (P<0.05). The age-standardized mortality rate of gastric cancer, female breast cancer, liver cancer, and esophageal cancer showed a downward trend (P<0.05). Conclusion The burden of cancer remains severe in Ya'an City. Targeted interventions should be implemented for lung cancer, colorectal cancer, female breast cancer, liver cancer, thyroid cancer, prostate cancer, and other common cancers to effectively control the cancer burden.

OBJECTIVES: To investigate the effects of early life intervention with Bifidobacterium bifidum BD-1 (B. bifidum BD-1) on hyperactivity in a female mouse model of attention deficit hyperactivity disorder (ADHD) and explore the underlying mechanisms. METHODS: Eight newborn female Wistar-Kyoto (WKY) rats and 6 spontaneous hypertensive rats (SHRs) were gavaged with saline and another 6 SHRs were gavaged with B. bifidum BD-1 (10⁹ CFU) daily for 3 weeks. Open field test of the rats was conducted at 7 weeks, and fecal samples were collected at weaning (3 weeks) and at 7 weeks for 16S rRNA sequencing. Immunofluorescent staining was used to detect dopamine transporter (DAT) and tyrosine hydroxylase (Th) levels in the striatum and activated microglia in the prefrontal cortex. Treg cells in the mesenteric lymph nodes, spleen and blood were analyzed using flow cytometry. RESULTS: The SHRs traveled a significantly greater distance in open fields test than WKY rats, and this behavior was significantly attenuated by B. bifidum BD-1 intervention. The expression of DAT and Th in the striatum was significantly lower in the SHRs than in WKY rats, while B. bifidum BD-1 treatment obviously increased Th levels in the SHRs. B. bifidum BD-1 intervention significantly deceased the number of activated microglia and increased Treg cell counts in the spleen of SHRs. The treatment also enhanced α diversity in gut microbiota of the SHRs and resulted in a decreased Firmicutes/Bacteroidota ratio, more active Muribaculaceae growth, and suppression of Clostridia_UCG-014 proliferation. CONCLUSIONS Early life intervention with B. bifidum BD-1 alleviates hyperactivity in female SHRs by modulating the gut microbiota and peripheral immune response, suppressing neuroinflammation and improving dopaminergic system function. These findings provide evidence for early prevention strategies and support the development and application of psychobiotics for ADHD.

Objective To investigate the role and mechanism of urate in chronic kidney disease complicated with renal interstitial fibrosis(CKD-RIF).Methods Mice were continuously fed with a diet containing 0.2％adenine for a duration of 9 weeks to establish mice models with CKD-RIF.By the end of the 9-week experimental periods,collected blood samples from the posterior orbital venous plexus of mice to measure renal functions and serum urate concentrations prior to euthanizing the mice.Hematoxylin-eosin(HE)staining and periodic acid-Schiff staining(PAS)were used to investigate the pathological alternations in kidney tissues.Masson's trichrome staining was used to observe the extent of renal fibrosis.Urate staining was used to detect urate deposition in renal tissues.Western blot and immunohistochemistry were used to detect the expression of target molecules.Scratch tests were used to ex-amine the migration abilities of cells treated with different concentrations of uric acid.Results The kidney function analysis showed that a significant increase in the levels of serum urea nitrogen(P=0.006 4),creatinine(P=0.008 0)and urate(P=0.000 7)in the CKD-RIF mice compared with the normal control group.The results of HE staining and PAS staining showed a significance of renal tubule injury and infiltration of inflammatory cells in the model group.Masson's trichrome staining showed that a marked increase in collagen deposition in the model group.The results of urate staining showed a significant presence of urate crystals in kidney tissue of the model group when compared to the control group.Animal tissue immunoblotting and immunohistochemistry analysis showed a significant increase in the expression levels of vimentin,α-SMA and TGF-β1 in the model group in comparison to the control group.Conversely,in the model group,E-cadherin levels exhibited a dramatic reduction compared to the control group.The findings from the scratching tests showed that uric acid significantly enhanced cell migration.Western blot analysis showed a dramatic increase in the expression levels of vimentin and α-SMA,while E-cadherin exhibited significant decrease in the cells subjected to uric acid treatment.Conclusion Urate stimulates the secre-tion of TGF-β1 by renal tubule epithelial cells and induces epithelial-mesenchymal transdifferentiation,thereby ex-acerbating renal interstitial fibrosis in CKD.

Objective To comprehensively analyze the clinical outcomes of total cavopulmonary connection (TCPC) in the treatment of functional single ventricle combined with heterotaxy syndrome (HS). Methods A retrospective analysis was conducted on the patients with functional single ventricle and HS who underwent TCPC (a HS group) in Guangdong Provincial People's Hospital between 2004 and 2021. The analysis focused on postoperative complications, long-term survival rates, and identifying factors associated with patient survival. Early and late postoperative outcomes were compared with matched non-HS patients (a non-HS group). Results Before propensity score matching, 55 patients were collected in the HS group, including 42 males and 13 females, with a median age of 6.0 (4.2, 11.8) years and a median weight of 17.0 (14.2, 28.8) kg. Among the patients, there were 53 patients of right atrial isomerism and 2 patients of left atrial isomerism. Eight patients underwent TCPC in one stage. TCPC procedures included extracardiac conduit (n=39), intracardiac-extracardiac conduit (n=14), and direct cavopulmonary connection (n=2). Postoperative complications included infections in 27 patients, liver function damage in 19 patients, and acute kidney injury in 11 patients. There were 5 early deaths. The median follow-up time was 94.7 (64.3, 129.8) months. The 1-year, 5-year, and 10-year survival rates were 87.2%, 85.3%, and 74.3%, respectively. After propensity score matching, there were 45 patients in the HS group and 81 patients in the non-HS group. Compared to the non-HS group, those with HS had longer surgical and mechanical ventilation time, higher infection rates (P<0.05), and a 12.9% lower 10-year survival rate. Multivariate Cox regression analysis identified asplenia was a risk factor for mortality (HR=8.98, 95%CI 1.86-43.34, P=0.006). Conclusion Compared to non-HS patients, patients with HS have lower survival rates after TCPC, and asplenia is an independent risk factor for the survival of these patients.

Objective: To investigate the effect of G protein-coupled receptor 108(GPR108) gene knockout on systemic inflammation in lipopolysaccharide(LPS)-induced sepsis mice. Methods: Male C57BL/6 mice and GPR108 gene knockout mice were randomly divided into 4 groups: WT group, WT-LPS group, KO group, KO-LPS group. The physiological characteristics of mice in different groups were observed, and the morphological changes of liver and lung tissues were observed. Macrophages were extracted from bone marrow and subjected to flow cytometry to detect their M1 polarization status. The expression levels of IL-6 in liver and lung tissues, macrophages, and serum were also measured. Results: KO-LPS group mice showed significant liver and lung tissue damage, with a significantly greater number of bone marrow-derived macrophages polarizing towards M1 in the KO-LPS group compared to the WT-LPS group. Additionally, at the tissue, cellular, and serum levels, the expression of IL-6 in the KO-LPS group mice was significantly higher than that in the WT-LPS group mice(P<0.05). Conclusion During the systemic inflammatory infection induced by LPS in mice, the lack of GPR108 exacerbates the systemic inflammatory response. GPR108 has an inhibitory effect on the inflammatory response in mice with LPS-induced sepsis.

Objective To make a preliminary investigation of the effect of the immune pathway mediated by live Lacticaseibacillus paracasei N11 15 on the development of primary hippocampal neurons cultured in vitro.Methods Live Lacticaseibacillus paracasei N1115 suspension of an appropriate concentration was used as the experimental group.Peptidoglycan(PGN)and lipopolysaccharide(LPS)were used as positive controls,and RPMI1640 medium served as the blank control.These were co-cultured with RAW264.7 cells to obtain the co-culture mediums and the total cellular RNA,and to measure the expression and secretion of cytokines.After centrifugation,the supernatants were co-cultured with primary hippocampal neurons at appropriate ratios.The co-culture mediums were collected,and the total cellular RNA was extracted to measure the expression of genes related to synaptic development in neurons.Following immunofluorescence staining of the primary hippocampal neurons,the presynaptic and presynaptic membrane-associated proteins,including synaptophysin(SYP)and the postsynaptic density protein 95(PSD95),and neuronal cell maturation markers,including microtubule-associated protein 2(MAP-2),and doublecortin(DCX)were quantitatively analyzed.Additionally,the morphological development of the neurons were measured.Results Compared with the blank control,the mRNA expression levels of interleukin(IL)-6 and tumor necrosis factor-α(TNF-α)increased by 7471％and 926％,respectively,after the RAW264.7 cells were treated with live Lacticaseibacillus paracasei N1115,while their secretion levels increased by 184.16 pg/mL and 12320.76 pg/mL,respectively,all showing statistically significant differences(P＜0.05).The activation ability of N1115 live bacteria was stronger than that of PGN but weaker than that of LPS,showing statistically significant differences(P＜0.05).Compared with the blank control,following the intervention with the supernatant from the co-culture of N1115 live bacteria and RAW264.7 cells,the viability of primary hippocampal neurons in the 10％supernatant intervention group increased by 19.25％,showing statistically significant differences(P＜0.05),and the mRNA expression of SYP and PSD95 increased by 137％and 159％,respectively,showing statistically significant differences(P＜0.05).The total neurite length(489.88 μm)of the neurons of the group intervened with the supernatant of N11 15 live bacteria was increased compared to that of the blank control group(381.51 μm),and the cell body area(2092.22 μm2),maximum neurite length(184.78 μm),total neurite length,average neurite length(108.38 μm),and branching points(4.84 s)were higher than those in the two positive control groups,showing statistically significant differences(P＜0.05).Conclusion Lacticaseibacillus paracasei N1115 can significantly activate the immune regulatory function of macrophages,thereby promoting the morphological development and synaptic function of nerve cells.
