Objective To evaluate the levels and changes in occupational individual external radiation dose in non-medical nuclear utilization units in Nanning City, and to provide a basis for radiation protection in such units. Methods Thermoluminescent dosimeters were used to monitor individual radiation doses among radiation workers in 38 non-medical nuclear utilization units in Nanning City. The results were subjected to statistical analysis. Results From 2021 to 2023, a total of 3724 person-times were monitored in 38 non-medical nuclear utilization units in Nanning City. The mean annual effective dose was 0.101 mSv in 2021, 0.060 mSv in 2022, and 0.094 mSv in 2023, with a three-year average of 0.085 mSv, all well below the occupational exposure limit of 1.0 mSv. Significant differences in mean annual effective doses were observed across occupations and sexes (P<0.05). Female workers received significantly lower mean annual effective dose than male workers. Workers in the cement manufacturing industry had a significantly higher mean annual effective dose compared to those in government institutions and industrial flaw detection practitioners (F = 2.913, P<0.05). No significant differences were found among workers exposed to unsealed radioactive sources, sealed radioactive sources, and radiation-generating equipment (F = 0.585, P>0.05). Conclusion The occupational individual external radiation doses in non-medical nuclear utilization units in Nanning City are at low levels. There are no significant differences in mean annual effective dose across different nuclear utilization units. However, differences in occupational roles between males and females significantly affect the mean annual effective dose.

OBJECTIVES: To analyze the differentially expressed exosomal miRNAs in patients with chronic heart failure (CHF) complicated by hyperuricemia (HUA) and explore their potential as novel diagnostic molecular markers and their target genes. METHODS: This study was conducted among 30 CHF patients with HUA (observation group) and 30 healthy volunteers (control group) enrolled between September, 2020 and September, 2023. Peripheral blood samples were collected from 6 CHF patients with HUA for analyzing exosomal miRNAs by high-throughput sequencing, and the results were validated in the remaining 24 patients using qRT-PCR. GO and KEGG enrichment analyses were performed to predict the the target genes of the identified differential miRNAs. We also validated the differentially expressed miRNAs by animal experiment. RESULTS: A total of 42 differentially expressed exosomal miRNAs were detected in observation group by high-throughput sequencing; among them, miR-27a-5p was significantly upregulated (P=0.000179), and miR-139-3p was significantly downregulated (P=0.000058). In the 24 patients with both CHF and PUA, qRT-PCR validated significant upregulation of miR-27a-5p (P=0.004) and downregulation of miR-139-3p (P=0.005) in serum exosomes. When combined, miR-27a-5p and miR-139-3p had a maximum area under the curve (AUC) of 0.899 (95% CI: 0812-0.987) for predicting CHF complicated by HUA. GO and KEGG enrichment analyses suggested that the differential expressions of miR-27a-5p and miR-139-3p was associated with the activation of the AMPK-mTOR signaling pathway to activate the autophagic response. We obtained the same conclusion from animal experiment. CONCLUSIONS Upregulated exosomal miR-27a-5p combined with downregulated exosomal miR-139-3p expression can serve as a novel molecular marker for diagnosis of CHF complicated by HUA, and their differential expression may promote autophagy in cardiomyocytes by activating the AMPK-mTOR signaling pathway.

OBJECTIVE To investigate the improvement effects of Runchang granules on the constipation in mice and its potential mechanism. METHODS The mice were randomly divided into normal control group， model group， Runchang granules low-dose and high-dose groups （5， 10 g/kg）， mosapride group （0.003 g/kg， positive control）， with 6 mice in each group. The latter 4 groups were given loperamide intragastrically （0.004 g/kg）， twice a day， for 3 consecutive days. Normal control group and model group were given purified water intragastrically， and administration groups were given relevant medicine intragastrically for 7 consecutive days. After the last medication， fecal moisture content and intestinal motility of mice were determined， while the structures of colon and ileum， and the secretion of colonic mucus were observed. Protein expressions of tyrosine kinase receptor （c-kit）， mucin 2 （MUC2） and stem cell factor （SCF） were determined in colon； meanwhile， the mRNA expression levels of inflammatory factors [tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， IL-1β， inducible nitric oxide synthase （iNOS）] as well as factors related to promoting intestinal motility [neuronal nitric oxide synthase （nNOS）， smooth muscle myosin light chain kinase （smMLCK）， 5-hydroxytryptamine 4 receptor （5-HT4R）， MUC2， SCF， c-kit] were determined. RESULTS Compared with model group， the fecal water content， intestinal propulsion rate， protein expression of c-kit in colon， relative expressions of MUC2 and SCF protein， and mRNA expressions of factors related to promoting intestinal motility （except for nNOS and SCF in Runchang granules low-dose group） were all increased significantly in Runchang granules low-dose and high-dose groups， and mosapride group （P＜0.05 or P＜0.01）. mRNA expression levels of inflammatory factors were decreased significantly（P＜0.05 or P＜0.01）. Both colon and ileum injuries improved， and the secretion of colon mucus was increased significantly in Runchang granules high-dose group （P＜0.01）. CONCLUSIONS Runchang granules have laxative effect and can improve constipation in mice， and its mechanism may be related to the promotion of the secretion of colon mucus and MUC2 expression， and the activation of SCF/c-kit signaling pathway.

BACKGROUND:There are differentially expressed genes in acute intracerebral hemorrhage,which are related to the occurrence and development of intracerebral hemorrhage. OBJECTIVE:To screen differentially expressed genes and key genes in brain tissue of a rat model with acute intracerebral hemorrhage,to validate them through qPCR,and to analyze the relationships between key genes and the neurological function and brain tissue water content after intracerebral hemorrhage. METHODS:Seventy-eight Sprague-Dawley rats were randomly divided into two groups:in intracerebral hemorrhage group,a rat model of acute intracerebral hemorrhage was made using collagenase injection at the right caudate nucleus;and in sham-operated group,rats were injected with equal amount of saline at the same site.RNA was extracted from rat brain tissues of both groups using the TRIzol method and transcriptome sequencing technology was used to identify differentially expressed genes in brain tissues of acute intracerebral hemorrhage,which were then verified by qPCR and analyzed for the relationships between the genes and neurological function and brain tissue water content after intracerebral hemorrhage.And the key genes were analyzed by GO and KEGG functional enrichment analysis in combination with bioinformatics. RESULTS AND CONCLUSION:Ten key genes were identified,including CXCL8,SERPINE1,TFPI2,CXCR4,GDA,KCNQ5,ERICH3,SCN3B,CACNA1E,and CCL20.The contents of GDA,KCNQ5,ERICH3,SCN3B,and CACNA1E in the intracerebral hemorrhage group were lower than those in the sham-operated group(P＜0.05).The contents of CXCL8,SERPINE1,TFPI2,CXCR4 and CCL20 in the intracerebral hemorrhage group were higher than those in the sham-operated group(P＜0.05).The contents of GDA,KCNQ5,ERICH3,SCN3B,and CACNA1E were positively correlated with brain tissue water content and neurologic deficit score(P＜0.05),while the contents of CXCL8,SERPINE1,TFPI2,CXCR4 and CCL20 were negatively correlated with brain tissue water content and neurologic deficit score(P＜0.05).GO analysis indicated that differentially expressed genes were mainly enriched in two biological processes(leukocyte chemotaxis and chemokine-mediated signaling pathways),two cell components(cation channel complexes and ion channel complexes),and two molecular functions(gated channel activity and ion channel activity).KEGG analysis indicated that differentially expressed genes were concentrated in tumor necrosis factor signaling pathway,glutamatergic synapses and GABAergic synapses.To conclude,the differentially expressed genes in intracerebral hemorrhage include CXCL8,SERPINE1,TFPI2,CXCR4,GDA,KCNQ5,ERICH3,SCN3B,CACNA1E,and CCL20,and these genes are related to brain tissue water content and neurological function after intracerebral hemorrhage.These genes are mainly enriched in cell components,binding functions,cellular protrusions,and other related biological functions.

The Spt-Ada-Gcn5-acetyltransferase (SAGA) is an ancillary transcription initiation complex which is highly conserved. The ADA1 (alteration/deficiency in activation 1, also called histone H2A functional interactor 1, HFI1) is a subunit in the core module of the SAGA protein complex. ADA1 plays an important role in plant growth and development as well as stress resistance. In this paper, we performed genome-wide identification of banana ADA1 gene family members based on banana genomic data, and analyzed the basic physicochemical properties, evolutionary relationships, selection pressure, promoter cis-acting elements, and its expression profiles under biotic and abiotic stresses. The results showed that there were 10, 6, and 7 family members in Musa acuminata, Musa balbisiana and Musa itinerans. The members were all unstable and hydrophilic proteins, and only contained the conservative SAGA-Tad1 domain. Both MaADA1 and MbADA1 have interactive relationship with Sgf11 (SAGA-associated factor 11) of core module in SAGA. Phylogenetic analysis revealed that banana ADA1 gene family members could be divided into 3 classes. The evolution of ADA1 gene family members was mostly influenced by purifying selection. There were large differences among the gene structure of banana ADA1 gene family members. ADA1 gene family members contained plenty of hormonal elements. MaADA1-1 may play a prominent role in the resistance of banana to cold stress, while MaADA1 may respond to the Panama disease of banana. In conclusion, this study suggested ADA1 gene family members are highly conserved in banana, and may respond to biotic and abiotic stress.

Objective:To investigate the effect and possible molecular mechanism of mannan-binding lectin-associated serine protease (MASP) 1 on the biological behavior of hepatocellular carcinoma(HCC) cells.Methods:From January 10 to October 25, 2022, 20 pairs of fresh liver cancer tissue and adjacent (3 cm from cancer tissue) normal tissue samples of patients who underwent hepatic cancer resection at the Affiliated Hospital of Nantong University were collected, and the expression of MASP1 was analyzed. From March 1, 2012 to May 20, 2017, the cancer tissue and adjacent (3 cm from cancer tissue) normal tissue samples of 67 patients with HCC were collected from the tissue sample bank of the Department of Pathology, the Affiliated Hospital of Nantong University and the correlation between the expression level of MASP1 and clinical data of patients with HCC were analyzed. Human hepatoma cells lines SK-Hep1 and Hep3B were cultured, and MASP1 overexpression and MASP1 knockdown cell lines were constructed. SK-Hep1 negative control group, SK-Hep1 MASP1 overexpression group, Hep3B negative control group and Hep3B MASP1 knockdown group were set up. The effect of MASP1 on the proliferation of HCC cells was detected by subcutaneous tumor transplantation experiment in nude mice. The effect of MASP1 on the expression of epithelial-mesenchymal transition related proteins (N-cadherin, matrix metalloproteinase 9(MMP9), and E-cadherin), and the effects of MASP1 on the expression of phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR) pathway related proteins and their phosphorylation levels were detected by Western blotting. Independent sample- t test, paired- t test and chi-square test were used for statistical analysis. Results:The results of immunohistochemical staining of 20 pairs of fresh tissue samples showed that the expression level of MASP1 in liver cancer tissue was lower than that in adjacent normal tissue (3.73±1.03 vs. 6.76±1.46), and the difference was statistically significant ( t=16.97, P<0.001). The correlation analysis of MASP1 expression level and clinical data of 67 patients with HCC revealed that the expression level of MASP1 was related to vascular invasion of the tumor, and the difference was statistically significant( χ2=5.20, P=0.023). The subcutaneous tumor transplantation experiment in nude mice showed that the volume and weight of subcutaneous tumor of mice in SK-Hep1 MASP1 overexpression group were lower than those of the SK-Hep1 negative control group((165.42±149.08) mm 3vs. (260.42±179.78) mm 3, (0.13±0.12) g vs. (0.18±0.12) g), and the differences were statistically significant ( t=5.15 and 3.89, both P<0.05). The results of Western blotting showed that the expression levels of N-cadherin and MMP9 in SK-Hep1 MASP1 overexpression group were lower than those of SK-Hep1 negative control group, while the expression level of E-cadherin was higher than that of SK-Hep1 negative control group (0.73±0.01 vs. 1.02±0.02, 0.40±0.01 vs. 0.69±0.01, 0.91±0.02 vs. 0.78±0.02), and the differences were statistically significant ( t=24.23, 36.87 and 9.27, all P<0.001). The expression levels of N-cadherin and MMP9 in Hep3B MASP1 knockdown group were higher than those in Hep3B negative control group, and the expression levels of E-cadherin was lower than that in Hep3B negative control group (1.04±0.01 vs. 0.31±0.01, 0.54±0.02 vs. 0.04±0.01, 0.56±0.01 vs. 0.93±0.01), and the differences were statistically significant ( t=163.20, 53.16, 60.74, all P<0.001). The expression levels of phosphoinositide PI3K, phosphoinositide Akt, and phosphoinositide mTOR of SK-Hep1 MASP1 overexpression group were lower than those of SK-Hep1 negative control group (0.59±0.01 vs.1.02±0.01, 0.64±0.01 vs. 1.12±0.02, 0.10±0.01 vs. 1.05±0.02); the expression levels of phosphoinositide PI3K, phosphoinositide Akt, and phosphoinositide mTOR of Hep3B MASP1 knockdown group were higher than those of Hep3B negative control group (0.96±0.01 vs. 0.55±0.01, 0.99±0.01 vs. 0.38±0.01, 0.93±0.02 vs. 0.06±0.01), and the differences were statistically significant ( t=40.87, 40.91, 87.30, 44.17, 107.50, 67.28, all P<0.001). Conclusions:The expression level of MASP1 is low in HCC tissue, and is significantly correlated with the poor prognosis of HCC patients and the occurrence of tumor vascular invasion. MASP1 may affect the proliferation and migration of liver cancer cells by regulating the PI3K/Akt/mTOR signaling pathway, suggesting that MASP1 may become a key gene in the treatment of HCC.
