Chronic kidney disease (CKD) is a global health problem, and its incidence increases year by year. Studies have revealed that the progression of CKD into end-stage renal disease (ESRD) is related to its inability to effectively eliminate toxins due to decreased renal function. Additionally, intestinal microflora produces a large amount of gut-derived uremic toxins (GDUTs) during protein fermentation. The theory of gut-kidney axis holds that gut and kidney interact with each other, and CKD reduces the ability to remove uremic toxins (UTs), resulting in the accumulation of UTs in the blood. The accumulation of UTs also accelerates the deterioration of renal function, leading to a vicious circle. This paper focused on the sources of indoxyl sulfate and p-cresol sulfate in GDUTs and their mechanisms against CKD (such as inducing renal tubular cell death, oxidative stress and endothelial injury, promoting renal fibrosis and down-regulating renal protective protein) as well as the sources of trimethylamine oxide and its mechanisms against CKD (such as promoting renal fibrosis and inflammation). Moreover, starting from gut-kidney axis, this paper summarized the ways of diet and nutrition regulation, toxin adsorption, enhanced dialysis to increase the clearance, inhibiting the sources of gut-derived toxins and traditional Chinese medicine (TCM) therapy (TCM preparations and TCM active ingredients) to regulate intestinal microecology and reduce the generation of GDUTs, aiming to provide new therapeutic ideas for delaying the progression of CKD.

Bivalves are species-rich mollusks with prominent protective roles in coastal ecosystems.Across these ancient lineages,colony-founding larvae anchor themselves either by byssus produc-tion or by cemented attachment.The latter mode of sessile life is strongly molded by left-right shell asymmetry during larval development of Ostreoida oysters such as Crassostrea hongkongensis.Here,we sequenced the genome of C.hongkongensis in high resolution and compared it to reference bivalve genomes to unveil genomic determinants driving cemented attachment and shell asymmetry.Importantly,loss of the homeobox gene Antennapedia(Antp)and broad expansion of lineage-specific extracellular gene families are implicated in a shift from byssal to cemented attachment in bivalves.Comparative transcriptomic analysis shows a conspicuous divergence between left-right asymmetrical C.hongkongensis and symmetrical Pinctada fucata in their expression profiles.Especially,a couple of orthologous transcription factor genes and lineage-specific shell-related gene families including that encoding tyrosinases are elevated,and may cooperatively govern asymmet-rical shell formation in Ostreoida oysters.

Objective:To explore the value of a radiomics nomogram based on T 1WI for prediction of the relapse of osteosarcoma after surgery within 1 year from multicenter data. Methods:The imaging and clinical data of 107 patients with pathologica1ly confirmed osteosarcoma who received neoadjuvant chemotherapy before surgery from 6 hospitals from January 2009 to October 2017 were retrospectively analyzed. A training cohort consisted of 75 patients from firstly enrolled 4 hospitals and an independent validation cohort of 32 patients from other 2 hospitals. Pretreatment T 1WI was used to extract radiomics features. Least absolute shrinkage and selection operator (LASSO) regression was applied to reduce the dimension and then the radiomics signature was constructed to predict the relapse of osteosarcoma after surgery within 1 year in training cohort. Independent clinical risk factors were screened using one-way logistic regression, and then a radiomics nomogram incorporated the radiomics signature and MRI characteristics was developed by multivariate logistic regression. The predictive nomogram was evaluated using receiver operating characteristic (ROC) curve in the training cohort, and validated in the independent validation cohort. The calibration curve was used to evaluate the agreement between prediction and actual observation and the decision curve was used to demonstrate the clinical usefulness. Results:Based on T 1WI from multicenter institutions, the radiomics signature was built using 2 valuable selected features that were significantly associated with relapse within 1 year. Two selected features included 1 gray-level co-occurrence matrices (GLCM) feature (L_G_1.0_GLCM_homogeneity1, LASSO coefficient 3.122) and 1 gray-level run length matrix (GLRLM) feature (GLRLM_RP, LASSO coefficient -2.474). The prediction nomogram including radiomics signature and MRI characteristics (joint invasion and perivascular involvement) showed good discrimination with the area under the ROC curve of 0.884 and 0.821 in the training and validation cohorts, respectively. The calibration curve showed that the nomogram achieved good agreement between prediction and actual observation. Decision curve analysis demonstrated that the radiomics nomogram was clinically useful when the threshold probability was greater than 21%. Conclusion:The radiomics nomogram based on T 1WI can be used as a non-invasive quantitative tool to predict relapse of osteosarcoma within 1 year before treatment, which provides support for clinical decision-making in osteosarcoma.

=2.071,P>0.05).Conclusions HCC patients with PVTT have larger tumor diameter and worse liver dysfunction,and are prone to peritoneal effusion.HCC patients with different LVI undergo surgery.There is better prognosis in HCC patients with BDTT,and good prognosis in patients with HVTT,while poorer prognosis in patients with PVTT.The postoperative survival of HCC patients with PVTT is associated with TT type,and patients will have better prognosis after tumor resection + TT removal if TT type is confirmed earlier.The postoperative survival of HCC patients with BDTT is not associated with TT type,tumor resection + TT removal maybe prolong postoperative survival time.

Objective:To evaluate the effect of antiviral therapy on HBV reactivation and liver function after liver resection in patients with hepatocellular carcinoma (HCC). Methods:A total of 174 HBV-DNA(?) HCC patients were recruited into two groups:antiviral ther-apy group (66 cases) and control group (108 cases). In the antiviral group, patients were given entecavir dispersible tablet, whereas no antiviral therapies were given in the control group. The HBV reactivation and liver function index rates were statistically analyzed. Re-sults:Rates of HBV reactivation after hepatectomy were 3.0%and 27.8%in the antiviral therapy group and control group, respectively. Multivariate analysis revealed that minor hepatectomy (HR, 4.695;95%CI, 1.257-17.537, P=0.021) and no antiviral therapy (HR, 8.164;95%CI, 1.831-36.397, P=0.006) were independent risk factors for HBV reactivation. The levels of ALT, TBil, ALB, and PT within 7 days af-ter liver resection were similar between the antiviral therapy group and the control group and between the reactivation group and no-reactivation group. However, the ALT and ALB levels were significantly better in the antiviral group compared with that in the control group after 30 days. Conclusion:HBV reactivation can occur after liver resection for HBV-DNA(?) HCC patients. Preoperative antiviral therapy can reduce the risk of HBV reactivation, thus protecting liver function in patients undergoing liver resection.

Objective To evaluate the reproducibility of normal liver ADC measurements by different respiratory motion compensation techniques. Methods A total of 31 young healthy volunteers who are 20 to 40 years old without any hepatic diseases were selected to research. Each volunteer underwent liver DWI twice in 24 hours with the same parameters and location. The imaging was performed with free-breath(FB), breathhold(BH), rspiratory-triggered(RT)and navigator-triggered(NT)techniques, and the ADC values of the left hepatic lobe and right hepatic lobe (upper, middle and lower) was acquired with two scans. Analysis the the ADC values of various anatomic locations of liver with two-way analysis of variance of randomized block design. Reproducibility of ADCs was assessed with the Bland-Altman method. Analysis of variance and paired-sample t test was used to assess ADCs from both right and left liver lobe among the four techniques. Result The ADC values acquired from the four techniques were significant differences (P<0.01),and the ADC values of the right lobe were less than the left lobe's(P<0.01). It showed a trend to decrease moving from superior to inferior levels in both left and right lobes, and the ADC values among The middle and lower were significant differences (P<0.01). The limit of agreement of ADC of twice imaging among the four techniques were as follow: the right lobe was less than the left lobes, and the breathhold was less the others. As the result, reproducibility in the right liver lobe was better to that in the left and the reproducibility with breathhold was better than the other respiratory motion compensation techniques. Conclusions Both anatomic location and DWI technique influence the liver ADC measurements and their reproducibility. The reproducibility of BH is the best.

Listeria monocytogenes (L. monocytogenes, LM) is an excellent tumor vaccine vector. In this study, recombinant LM vaccine candidate expressing human papillomavirus type 16 (HPV16) E7 protein was constructed and its charactericts were determined. Through homologous recombination, E7 gene was cloned in frame with the LM4 Phly promoter-signal sequence, and introduced into the chromosome of LM4. The recombinant strain named LM4△hly::E7 with the plasmid-free and antibiotic-resistant gene-free was constructed. LM4△hly::E7 could express and secrete E7-LLO fusion protein; its size is 66 kDa and has immunological activity. Furthermore, LM4△hly::E7 could multiply in RAW264.7 macrophages by confocal laser scanning microscope. Additionally, LM4△hly::E7 could induce specific antibodies against E7 in immunized mice in ELISA. Also, the 50% lethal dose (LD₅₀) of LM4△hly::E7 strain was 3.863×10⁹ CFU (Colony-Forming Units) in C57BL/6 mice with intraperitoneal immunization, which was more attenuated than wild type LM4. Mice immunized with LM4△hly::E7 did not show obvious pathological change. These data show that LM4△hly::E7 expressing E7-LLO fusion protein has good safety, which may provide the materials for research of antitumor effect and would be a promising vaccine candidate for cervical cancer.
