Objective:To investigate the expression of heterogeneous nuclear ribonucleoprotein A2B1 (HNRNPA2B1) in human esophageal cancer tissues and its clinical significance.Methods:Single-cell data for esophageal cancer were downloaded from the Gene Expression Omnibus (GEO) database (GSE160269 dataset, last updated on November 29, 2020) to analyze the expression of HNRNPA2B1. Transcriptional sequencing data for esophageal cancer from The Cancer Genome Atlas (TCGA) database, including the fragments per kilobase of transcript per million mapped reads (FPKM) quantitative data (173 samples, consisting of 162 esophageal cancer tissues and 11 adjacent normal tissues), and survival data in the phenotype category were downloaded. Analysis of FPKM quantitative data from the TCGA database for esophageal cancer was performed. The top 250 genes most correlated with HNRNPA2B1 were selected and the R4.3.0 clusterProfiler package was used to conduct Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses on the selected gene set. FPKM quantitative data from the TCGA database for esophageal cancer were imported into the CIBERSORTx website to obtain immune cell abundance scores, and the correlation between HNRNPA2B1 and the degree of immune cell infiltration was analyzed. The clinicopathological data of patients from esophageal cancer tissue microarrays including 114 cases of esophageal squamous cell carcinoma tissues and 66 cases of adjacent normal tissues were collected. The patients underwent surgery from January 2006 to December 2008, and the follow-up period extended until July 2015. Cytokeratin (CK) and HNRNPA2B1 expression in esophageal cancer tissue microarrays were detected by using multi-color immunohistochemical (mIHC) staining, and multispectral tissue imaging was conducted. The R4.3.0 survival package and survminer package in TCGA database were used to calculate the optimal cut-off value of HNRNPA2B1 expression and the proportion of CK + HNRNPA2B1 + cells in tissue microarrays was used to calculate the cut-off value of HNRNPA2B1 expression based on which patients were categorized into high and low expression groups. The overall survival (OS) of both groups was compared and the factors influencing OS were analyzed by using the Cox proportional hazards model. Results:In the GSE160269 dataset of single-cell data for esophageal cancer, the expression level of HNRNPA2B1 in tumor epithelial cells was higher than that in normal epithelial cells, and HNRNPA2B1 was highly expressed in various immune cell subtypes. The high expression level of HNRNPA2B1 was positively correlated with regulatory T cells, naive B cells and memory CD4 + T cells. GO enrichment analysis revealed that HNRNPA2B1 was primarily involved in the biological process of nuclear division, cellular components were mainly enriched in chromosomal regions, and molecular functions were mainly enriched in ATP hydrolysis activity. KEGG enrichment analysis indicated that HNRNPA2B1 was primarily involved in biological processes such as the cell cycle, spliceosome, and DNA replication. Results from mIHC and multispectral tissue imaging demonstrated that CK was predominantly expressed in the cell membranes of tumor cells and normal esophageal epithelial cells, while HNRNPA2B1 was primarily expressed in the nuclei of tumor cells and normal esophageal cells. The expression level of HNRNPA2B1 in esophageal cancer tissues was higher than that in the normal paracancerous tissues ( U = 2 984.00, P < 0.05). Results of tissue microarrays and the survival analysis on the data in the TCGA database indicated that esophageal cancer patients with low HNRNPA2B1 expression had a better OS compared to those with high expression (both P < 0.05). Cox multivariate regression analysis revealed that age ( HR = 1.919, 95% CI: 1.158-3.182, P = 0.011), TNM stage ( HR = 2.404, 95% CI: 1.374-4.207, P = 0.002), T stage ( HR = 2.349, 95% CI: 1.150-4.789, P = 0.019), and the expression of HNRNPA2B1 in tumor epithelial cells ( HR = 2.160, 95% CI: 1.280-3.647, P = 0.004) were independent factors influencing OS in esophageal cancer patients. Conclusions:The high expression of HNRNPA2B1 protein in esophageal cancer tissues may play a role in the developement and progression of esophageal cancer, serving as a crucial biological indicator for prognostic assessment of esophageal cancer.

Objective: To evaluate the efficacy and safety of fecal microbiota transplantation (FMT) in the treatment of autism spectrum disorder (ASD). Methods: A longitudinal study was conducted. Clinical data from ASD patients with gastrointestinal symptoms and who underwent FMT in the Tenth People's Hospital affiliated to Tongji University or Jinling Hospital between May 2012 to May 2021 were retrospectively collected. Scores derived from the autism behavior checklist (ABC), the childhood autism rating scale (CARS), the Bristol stool form scale (BSFS), and the gastrointestinal symptom rating scale (GSRS) were analyzed at baseline and at the 1st, 3rd, 6th, 12th, 24th, 36th, 48th and 60th month after FMT. Records of any adverse reactions were collected. Generalized estimating equations were used for analysis of data on time points before and after FMT. Results: A total of 328 patients met the inclusion criteria for this study. Their mean age was 6.1±3.4 years old. The cohort included 271 boys and 57 girls. The percentage of patients remaining in the study for post-treatment follow-up at the 1st, 3rd, 12th, 24th, 36th, 48th and 60th month were as follows: 303 (92.4%), 284 (86.7%), 213 (64.9%), 190 (57.9%), 143 (43.6%), 79 (24.1%), 46 (14.0%), 31 (9.5%). After FMT, the average ABC score was significantly improved in the first 36 months and remained improved at the 48th month. However, the average score was not significantly different from baseline by the 60th month (1st-36th month, P<0.001; 48th month, P=0.008; 60th month, P=0.108). The average CARS score improved significantly during the first 48 months and remained improved at the 60th month (1st-48th month, P<0.001; 60th month, P=0.010). The average BSFS score was also significantly improved in the first 36 months (with an accompanying stool morphology that resembled type 4). This improvement was maintained at the 48th month. However, the average score was similar to baseline at the 60th month (1st-36th month, P<0.001; 48th month, P=0.008; 60th month, P=0.109). The average GSRS score was significantly improved during the first 24 months, but not afterwards (1st-24th month, P<0.001; 36th month, P=0.209; 48th month, P=0.996; 60th month, P=0.668). The adverse events recorded during treatment included abdominal distension in 21 cases (6.4%), nausea in 14 cases (4.3%), vomiting in 9 cases (2.7%), abdominal pain in 15 cases (4.6%), diarrhea in 18 cases (5.5%), fever in 13 cases (4.0%), and excitement in 24 cases (7.3%). All adverse reactions were mild to moderate and improved immediately after suspension of FMT or on treatment of symptoms. No serious adverse reactions occurred. Conclusion: FMT has satisfactory long-term efficacy and safety for the treatment of ASD with gastrointestinal symptoms.

The plant root-associated microbiomes include root microbiome and rhizosphere microbiome, which are closely related to plant life activities. Nearly 30% of photosynthesis products of plants are used to synthesize root compounds, there is evidence that root compounds regulate and significantly affect the root microbiome Tanshinones are the main hydrophobic components in Salvia miltiorrhiza. In order to study whether these compounds can regulate the root-associated microbiomes of S. miltiorrhiza, our study first identified a white root S. miltiorrhiza(BG) which contains little tanshinones. Retain of the fifth intron of tanshinones synthesis key enzyme gene SmCPS1 leading to the early termination of the SmCPS1 gene, and a stable white root phenotype. Further, wild type(WT) and BG were planted in greenhouse with nutrient soil(Pindstrup, Denmark) and Shandong soil(collected from the S. miltiorrhiza base in Weifang, Shandong), then high-throughput sequencing was used to analyze the root-associated microbiomes. The results showed that the tanshinones significantly affected the root-associated microbiomes of S. miltiorrhiza, and the impact on root microbiomes was more significant. There are significant differences between WT and BG root microbiomes in species richness, dominant strains and co-occurrence network. Tanshinones have a certain repelling effect on Bacilli which belongs to Gram-positive, while specifically attract some Gram-negative bacteria such as Betaproteobacteria and some specific genus of Alphaproteobacteria. This study determined the important role of tanshinones in regulating the structure of root-associated microbiomes from multiple angles, and shed a light for further improving the quality and yield of S. miltiorrhiza through microenvironment regulation.

OBJECTIVE: To study the mechanism of the anti-tumor effect of Morinda citrifolia (noni). METHODS: The influences of noni juice on cell proliferation, apoptosis, invasion, migration and the activity of AKT/nuclear factor- κ B (NF- κ B) signaling pathway in A549 human lung cancer cells were detected by MTT, cell counting kit-8, colony formation, Annexin V/PI double labeling, transwell, scratch test and immunoblotting assay, respectively. A549 cells were inoculated into the right axilla of nude mice, followed by noni juice treatment. The body weight of the nude mice was weighed, and the tumor volume and weight were measured. Cell proliferation and expression of apoptosis-related proteins were measured by immunohistochemistry, and the activity of NF- κ B signaling pathway was measured by immunoblotting. RESULTS: The in vitro studies showed that noni juice inhibited the A549 cells proliferation, migration and invasion. Noni juice also promoted cells apoptosis in A549 cells. Immunoblotting assay showed that the phosphorylation level of AKT, p50, and STAT3 proteins was inhibited to different extents after noni juice treatment. The in vivo studies showed that noni juice effectively suppressed tumor formation of A549 cells in nude mice. Noni juice treatment inhibited the expression of Ki67, PCNA, and Bcl-2 protein in the tumor; while promoted the expression of caspase-3 protein. Additionally, we also found that noni juice treatment could restrain the activity of AKT/NF- κ B signaling pathway in the tumor tissue. CONCLUSION Noni juice inhibited the proliferation of A549 lung cancer cells, induced apoptosis, and inhibited cell invasion and migration via regulating AKT/NF- κ B signaling pathway.

Small for gestational age ( SGA ),one of the major adverse pregnancy outcomes, significantly increases the risk of perinatal death and metabolic diseases in adulthood. It is of great significance to strengthen early surveillance and intervention for SGA prevention. Dyslipidemia during pregnancy, as a common metabolic disorder, has been considered to correlate with the increased risk of SGA; however, the epidemiological evidence is still controversial. We have systematically reviewed the recent studies related to the association between serum lipid level during pregnancy and the risk of SGA, so as to provide reference for prevention and intervention of SGA.

Objective:To investigate the predicting value of cardiac serum troponin I (cTnI) levels for the clinical outcome of patients with aneurismal subarachnoid hemorrhage (aSAH) after endovascular coil embolization.Methods:Patients with aSAH treated with endovascular coil embolization in the Department of Neurology, Fujian Provincial Hospital from January 2017 to December 2019 were enrolled retrospectively. The baseline data, clinical grade, serum cTnI and N-terminal-pro B-type natriuretic peptide (NT-proBNP) levels, electrocardiogram, aneurysm characteristics, endovascular treatment status, and complications of the patents were collected. The outcomes were evaluated by the modified Rankin Scale (mRS) at 90 d after onset. Poor outcome was defined as >2 points. Multivariate logistic regression analysis was used to identify the independent risk factors for poor outcomes. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of serum cTnI levels for poor outcomes. Results:A total of 316 patients were enrolled, among them, 256 had good outcomes (81.01%), 60 had poor outcomes (18.99%) and 13 died (4.11%). Forty-seven patients (14.87%) had elevated serum cTnI levels. The proportion of patients with elevated serum cTnI levels in the poor outcome group was significantly higher than that in the good outcome group (45% vs. 7.81%; P<0.001). Compared with the good outcome group, the Glasgow Coma Scale score of the poor outcome group was lower, and the Hunt-Hess grades and Fisher grades were higher ( P<0.001). The proportion of patients with elevated NT-proBNP levels and abnormal electrocardiogram in the poor outcome group (all P<0.001) were also significantly higher than those in the good outcome group. The proportion of receiving stent-assisted coil embolization, cerebrospinal fluid replacement and ventricular drainage, as well as the incidence of complicated with cerebral infarction, hydrocephalus, seizure and rebleeding in the poor outcome group were significantly higher than those in the good outcome group (all P<0.01). Multivariate logistic regression analysis showed that after adjusting for other confounding factors, Hunt-Hess grading 3-5 (odds ratio [ OR] 6.615, 95% confidence interval [ CI]2.158-20.278; P=0.001), Fisher grading 3-4 ( OR 3.719, 95% CI 1.479-9.352; P=0.005), cerebral infarction ( OR 15.814, 95% CI 4.978-50.235; P<0.001), rebleeding ( OR 13.324, 95% CI 2.092-84.881, P=0.006) and elevated serum cTnI levels ( OR 3.874, 95% CI 1.406-10.672; P=0.009) were significantly and independently associated with the poor outcomes, which could independently predict the poor outcomes after the onset of aSAH at 90 d. The area under the ROC curve for serum cTnI levels predicting poor outcomes was 0.747 (95% CI 0.666-0.828; P<0.001). The best cut-off value was 0.025 μg/L, the sensitivity and specificity were 60.0% and 87.9%, respectively. Conclusion:The elevated serum cTnI levels have certain predictive value for the poor outcomes of patients with aSAH after endovascular coil embolization.
