Objective To observe the expression of Galectin-3 in peritoneal dialysis (PD) fluid in patients with different dialysis ages, and to conduct correlation analysis with vascular endothelial growth factor (VEGF) , fi-bronectin (FN) and related clinical indicators.Methods A total of 109 PD patients who were regularly followed up in the department of nephrology were divided into four groups according to different peritoneal dialysis ages.The concentrations of Galectin-3, VEGF and FN were determined by enzyme-linked immunosorbent assay.The expres-sion of Galectin-3 in peritoneal dialysate of the 4 groups was compared, the correlation with VEGF, FN and clinical related indexes was analyzed, and the correlation was analyzed by Spearman test.Results The concentration of VEGF in peritoneal dialysis patients in group D significantly increased (P<0.05) .Galectin-3 expression levels were positively correlated with VEGF (r =0.358 , P =0.022) , but not significantly correlated with FN (r =0.121, P=0.452).Galectin-3 was positively correlated with clinical indicators parathyroid hormone (PTH) (r=0.201, P=0.037), C-reactive protein (CRP) (r=0.357, P<0.001), left ventricular posterior wall dimensions (LVPWD) (r=0.213, P=0.026), and negatively correlated with clinical indicators total cholesterol (TC) (r=-0.316, P=0.001).Conclusion The concentration of Galectin-3 in the dialysate of long-term peritoneal dialy-sis patients is significantly elevated, indicating that the expression of galectin-3 increases with the extension of peri-toneal dialysis time, suggesting that the detection of galectin-3 levels may be helpful for the evaluation of early peri-toneal fibrosis.The positive correlation with VEGF may suggest its role in promoting peritoneal angiogenesis and fi-brosis.Moreover, it is positively correlated with clinical indicators PTH, CRP and LVPWD, suggesting that it has certain clinical guiding significance on microinflammatory state and myocardial remodeling.

Objective To analyze the transcriptome data of Zika virus(ZIKV)-infected human neuroblastoma cells SH-SY5Y by bioinformatics method,and to identify the potential genes involved in the pathogenic mechanism of ZIKV.Methods SH-SY5Y cells were infected with ZIKV.The total RNA was extracted and the differentially expressed genes(DEGs)were screened by transcriptome sequencing.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were performed to predict the biological processes,molecular functions,and signaling pathways mainly involved in the DEGs,and the results were verified by quantitative polymerase chain reaction(qPCR).Results A total of 259 DEGs were identified,including 172 up-regulated genes and 87 down-regulated genes.GO functional enrichment analysis showed that the DEGs were mainly related to extracellular matrix,response to stimulus,antimicrobial humoral response,and developmental process.KEGG pathway enrichment analysis revealed that the DEGs were predominantly associated to inflammatory reaction and immune response.The qPCR validation results of DEGs were basically consistent with the transcriptome sequencing results.Conclusion The expression of genes involved in extracellular matrix,response to stimulus,and regulation of inflammatory reaction is significantly altered in SH-SY5Y cells after ZIKV infection,suggesting that ZIKV may cause neurological lesions by remodeling the extracellular matrix and regulating inflammatory reaction.

Background/Aims: Inflammatory bowel disease (IBD) may contribute to the development of hematologic malignancies. In this study, the potential relationship between IBD and hematologic malignancies was investigated. Methods: We searched the PubMed, Web of Science, Embase, and Cochrane Library databases for all cohort studies comparing the incidence of hematologic malignancies in non-IBD populations with that in IBD patients, and we extracted relevant data from January 2000 to June 2023 for meta-analysis. Results: Twenty cohort studies involving 756,377 participants were included in this study. The results showed that compared with the non-IBD cohort, the incidence of hematologic malignancies in the IBD cohort was higher (standardized incidence ratio [SIR]=3.05, p<0.001). According to the specific types of IBD, compared with the non-IBD patients, the incidences of hematologic malignancies in ulcerative colitis patients (SIR=2.29, p=0.05) and Crohn's disease patients (SIR=3.56, p=0.005) were all higher. In the subgroup analysis of hematologic malignancy types, compared with the control group, the incidences of non-Hodgkin's lymphoma (SIR=1.70, p=0.01), Hodgkin's lymphoma (SIR=3.47, p=0.002), and leukemia (SIR=3.69, p<0.001) were all higher in the IBD cohort. Conclusions The incidence of hematologic malignancies, including non-Hodgkin's lymphoma, Hodgkin's lymphoma, and leukemia is higher in patients with IBD (ulcerative colitis or Crohn's disease) than in non-IBD patients.

Objective:To explore the value of MRI signs in assessing the presence or absence of hernia sacs in fetuses with congenital diaphragm hernia.Methods:MRI images of 57 patients with congenital diaphragm hernia confirmed by postpartum surgery were analyzed from November 2016 to December 2020 in Xinhua Hospital, Shanghai Jiao Tong University School of Medicine, with a gestational age of 20－40 (28±5) weeks. In postpartum surgery, 18 cases were found with hernia sacs (hernia sac group) and 39 cases without hernia sacs (hernia-free group). Seven MRI signs were analyzed, including hernia peripheral enveloping sensation, smooth lung-hernia interface, crescent-shaped lung compression, residual lung tissue on the affected side, heart displacement, effusion above the lung-hernia interface and effusion below the lung-hernia interface. The differences in MRI signs between the hernia sac and hernia-free groups were compared using the χ 2 test or Fisher′s exact probability method. The diagnostic efficacy of each sign was calculated. The MRI signs with statistical differences between the two groups were included in the predictive integration model, and 1 point was scored for each sign, the imaging score of each fetus was calculated, and the efficacy of imaging points in diagnosing the presence or absence of hernia sacs was assessed by the subject manipulation receiver operating characteristics (ROC) curve. Results:There were statistically significant differences in 5 MRI signs between the hernia sac and the hernia-free groups, namely hernia peripheral enveloping sensation (χ2=25.74, P<0.001), smooth lung-hernia interface (χ2=48.20, P<0.001), crescent-shaped lung compression (χ2=57.00, P<0.001), residual lung tissue on the affected side (χ2=12.14, P<0.001) and effusion above the lung-hernia interface (χ2=4.31, P=0.022). Among them, the sign of crescent-shaped lung compression had the highest diagnostic efficacy, and the sensitivity, specificity and accuracy all were 100%. Five statistically significant MRI signs were included in the predictive integration model, and the area under the ROC curve was 0.999, the sensitivity was 100%, the specificity was 94.9%, and the optimal threshold was 2 points. Conclusion:Fetal MRI signs and predictive integration model can effectively identify the presence or absence of hernia sacs in fetuses with congenital diaphragm hernia, which has certain clinical significance.

Objective:To investigate the expression changes of farnesoid X receptor (FXR) in the evolution of normal intestinal mucosa, colorectal adenoma (CRA) and colorectal cancer (CRC), and the correlation of FXR expression with clinicopathological features and prognosis of patients with colorectal tumors.Methods:The UALCAN website tool was used to analyze the expression level of FXR gene transcripts of CRC and normal colorectal tissues in The Cancer Genome Atlas (TCGA) database. The patients undergoing colonoscopy and treatment in the Aerospace Center Hospital from January 2019 to September 2020 were selected, and the immunohistochemistry was used to detect the expression of FXR protein in 100 CRA tissues, 47 CRC tissues and 11 normal colonic mucosal tissues from healthy people (healthy control). Combining with clinical data, the relationship between FXR protein expression and clinicopathological characteristics of patients with colorectal tumors was analyzed. According to the Kaplan-Meier Plotter online database, the median expression level of FXR gene transcripts in CRC patients was analyzed, and the patients were divided into FXR low-expression group and high-expression group, the relationship between the expression of FXR gene and prognosis of CRC patients was investigated.Results:The analysis of data from TCGA database showed that the expression level of FXR gene transcripts in CRC tissues was lower than that in normal colorectal tissues ( P < 0.01). Immunohistochemical examination of the collected tissues showed that the positive rate of FXR protein gradually decreased from the cecum to the rectum. The positive rates of FXR protein in healthy control, CRA patients and CRC patients were 90.9% (10/11), 24.0% (24/100), 6.3% (3/47), and the difference was statistically significant ( χ2 = 35.56, P < 0.01); the positive rate of FXR protein in cancer tissues from CRC patients was lower than that in normal tissues adjacent to cancer [6.3% (3/47) vs. 65.2% (15/23)], and the difference was statistically significant ( χ2 = 27.98, P < 0.01). There was no statistical difference in the positive rate of FXR among CRA patients with different gender, age, maximum diameter of adenoma, and aggression (all P > 0.05). There was also no statistical difference in the positive rate of FXR among CRC patients with different gender, age, tumor site, maximum diameter of tumor, degree of differentiation, TNM staging, and vascular tumor thrombus (all P > 0.05). According to the survival analysis of Kaplan-Meier Plotter online database, the recurrence-free survival of CRC patients with high expression of FXR was better than that of patients with low expression of FXR ( P = 0.003). Conclusions:The expression level of FXR gradually decreases in the intestinal tissues of healthy people, CRA patients and CRC patients. The prognosis of CRC patients with low FXR expression is poor.

Objective:To explore the association between maternal bisphenol A (BPA) exposure during pregnancy and neurobehavioral development in infant.Methods:Participants were from the Ma’anshan Birth Cohort, which was established from October 2008 to October 2010 based on four municipal medical and health institutions in Ma'anshan. High-performance liquid chromatography-tandem mass spectrometry was applied for the determination of serum BPA concentration in 1 783 pregnant women sampled at their first filing, and during 2.97 to 28.1 months age of the infants. Neurobehavioral development were assessed by 0-6-year-old pediatric examination table of neuropsychological development. Generalized linear model was used to analyze the association between serum BPA levels during pregnancy and infants’ neurobehavioral development.Results:A total of 931 mother-child pairs had complete data on serum BPA detection during pregnancy and assessment of infants’ neurobehavioral development status. The age of pregnant women at their first filing was (26.67±3.45) years old, and the M ( P25, P75) of serum BPA concentration (ng/ml) was 0.23 (0.11, 0.52), with a detection rate of 84.1% (783/931). The age of infants was (13.18±5.46) months, and 53.5% (498) were boys. The developmental quotient scores of large motor, fine motor, adaptive ability, language ability and social behaviors of infants were (97.88±16.32), (97.16±15.35), (99.64±15.47), (95.3±16.04) and (98.95±14.76) points, respectively. Generalized linear model showed that after adjusting for factors such as delivery mode, feeding mode, family per capita monthly income, preterm delivery, gender, maternal age, residence, pre-pregnancy body mass index and residence time, serum BPA level in pregnancy was negatively associated with infant’s development of social behavior [β (95% CI):-2.42 (-4.71, -0.12)]. The post-stratification analysis by infant age revealed that the serum BPA level in pregnancy was only negatively associated with the development of language and social behavior developmental quotient scores in infants between the ages of 12 and 18 months, with β (95% CI) about -6.66 (-13.06, -0.25) and -7.401 (-12.97, -1.83), respectively. Conclusion:BPA exposure during pregnancy affects language and social behavior development in infants, and the detection window is between 12 and 18 months old of the infant.

Objective To investigate the clinicopathologic features and possible causes of granulomatous lobular mastitis(GLM). Methods Three hundred cases of GLM were collected from surgical specimens diagnosed at Longhua Hospital, Shanghai University of Traditional Chinese Medicine from January 2015 to November 2017. Morphologic features were reviewed using HE staining. A total of 116 cases were investigated by Gram staining. The expression of CD3, CD20, CD68, IgG, IgG4, CD38 and CD138 was detected by immunohistochemical staining. Results The age of the patients was 23 to 47 years and the median age was 32 years. All patients were female, 96.7% (290/300) had a history of lactation.There were 143 cases of left breasts, 138 cases of right breast and 19 cases of bilateral breasts. Serum prolactin increased in 39.7%(119/300) patients. Within 15.7%(47/300) of patients were associated with nodular erythema or joint swelling and pain of the lower extremities. Pathological observation showed that lobular?centric suppurative granulomatous inflammation, accompanied by dilatation of intralobular and interlobular ducts. There were 16 cases accompanied with duct ectasia. Immunohistochemistry showed CD3?positive lymphocytes were more than CD20?positive lymphocytes in the peripheral aggregation zone of neutrophils within granulomatous lesions. Gram positive bacteria were found in the lipid vacuoles of the 51.7%(60/116) patients. Conclusions GLM has distinctive histologic features. It may be related to corynebacterium infection, or accompanied by the increase of serum prolactin and erythrocyte sedimentation rate. The age, location and history of the disease are importance in the diagnosis and differential diagnosis.

Objective: To study serum zinc level in pregnancy and umbilical cord blood and their association with newborn birth weight. Methods: Pregnant women accepting obstetric examination in Ma'anshan Maternal and Child Care Center were recruited from May 2013 to September 2014. The follow up was conducted during their first, second and third trimesters of pregnancy and the self-designed questionnaire was used to collect information of social and demographic characteristics. Blood samples in the first, second pregnancy period and umbilical cord blood samples were collected and serum concentrations of zinc were assayed. 3 239 mother-infant entered the final analysis. We divided serum zinc level into low (<P₂₅), medium (P₂₅-P₇₅) and high (>P₇₅) groups according to their exposure concentrations at each trimesters. Non-conditional multivariate logistic regression model was conducted to evaluate the association between serum zinc level in first, second trimesters of pregnancy and umbilical cord blood with small for gestational age (SGA) and large for gestational age (LGA). Results: Serum zinc level in P₅₀ (P₂₅-P₇₅) during the first, second trimesters and cord blood were 1 016.18 (907.09-1 145.60), 813.36 (732.47-897.89) and 903.44 (808.71-1 015.64) μg/L, respectively. The prevalence of zinc deficiency during the first, second trimesters and cord blood were 1.5% (44/2 957), 15.9% (492/3 087) and 6.5% (176/2 707), respectively. The prevalence of total SGA and LGA were 9.7% (313/3 239) and 16.5% (536/3 239), respectively. Compared to high-level serum zinc group, the risk of SGA (OR (95%CI) in low-level serum zinc group during first trimesters was 1.51 (1.05-2.19)). Serum zinc level among second pregnancy period and umbilical cord blood had no statistically significant effect on SGA and LGA (both P values >0.05). Conclusion Zinc nutritional status of pregnant women in Ma'anshan city was at a good level. The low serum zinc level in first trimester increased the risk of SGA.
