Identification of the iridoids of Hedyotis diffusa Willd and its mechanism on renal fibrosis based on network pharmacology / 药学学报

To identify the composition of iridoids from Hedyotis diffusa Willd and explore the mechanism on its anti-renal fibrosis effect based on network pharmacology, LC-Q/TOF-MS (liquid chromatograpy-quadrupole/time of flight mass spectrometry) was used to analyze the iridoid ingredients and the related targets of renal fibrosis were obtained by DisGeNET database and MalaCards database. The potential targets were screened by SYBYL-X7.3 software. We then imported the identified ingredients and potential target genes into Cytoscape3.7.1 to construct the compound-target network and the protein-protein interaction (PPI) network. Finally, the gene ontology (GO) functional enrichment analysis and KEGG pathway enrichment analysis of the selected core genes were made to explore the mechanism of iridoids against renal fibrosis. There were 10 active iridoid compounds and 111 corresponding targets including dimethylarginine dimethylaminohydrolase 1 (DDAH1), heparanase (HPSE), human kirsten rat sarcoma viral oncogene (KRAS), moesin (MSN), etc. in compound-target network. The GO functional enrichment analysis obtained 211 GO entries. Twenty related signal pathways including Toll-like receptor signaling pathway, transforming growth factor-beta (TGF-β) signaling pathway, renal cell carcinoma signaling pathway, and the Janus kinase/signal transducer and activator of tran-ions (Jak-STAT) signaling pathway were selected by KEGG enrichment analysis. We preliminarily investigated the mechanism of the iridoid compounds on renal fibrosis to provide guide information for the subsequent experimental research and clinical application.

Pretreatment elevated fibrinogen level predicts worse oncologic outcomes in upper tract urothelial carcinoma / 亚洲男科学杂志(英文版)

This study aimed to further validate the prognostic role of fibrinogen in upper tract urothelial carcinoma (UTUC) in a large Chinese cohort. A total of 703 patients who underwent radical nephroureterectomy were retrospectively identified. Fibrinogen levels of ≥4.025 g l-1 were defined as elevated. Logistic regression analysis was performed to determine the association between fibrinogen and adverse pathological features. Kaplan-Meier analysis and Cox regression models were used to assess the associations of fibrinogen with cancer-specific survival (CSS), disease recurrence-free survival (RFS), and overall survival (OS). Harrell c-index and decision curve analysis were used to assess the clinical utility of multivariate models. The median follow-up duration was 42 (range: 1-168) months. Logistic regression analysis revealed that elevated fibrinogen was associated with higher tumor stage and grade, lymph node involvement, lymphovascular invasion, sessile carcinoma, concomitant variant histology, and positive surgical margins (all P < 0.05). Multivariate Cox regression analysis demonstrated that elevated fibrinogen was independently associated with decreased CSS (hazard ratio [HR]: 2.33; P < 0.001), RFS (HR: 2.09; P < 0.001), and OS (HR: 2.09; P < 0.001). The predictive accuracies of the multivariate models were improved by 3.2%, 2.0%, and 2.8% for CSS, RFS, and OS, respectively, when fibrinogen was added. Decision curve analysis showed an added benefit for CSS prediction when fibrinogen was added to the model. Preoperative fibrinogen may be a strong independent predictor of worse oncologic outcomes in UTUC; therefore, it may be valuable to apply this marker to the current risk stratification in UTUC.

The application of MSCT 3D reconstruction technology without contrast on pulmonary arteriovenous malformation / 实用放射学杂志

Objective To evaluate the application of MSCT 3D reconstruction technology without contrast on pulmonary arterio-venous malformation(PAVM).Methods The clinical and imaging data of 12 cases with PAVM confirmed by DSA were analyzed ret-rospectively.The plain scan with 16 slice spiral CT scanner performed pulmonary 3D reconstruction at post-processing work station by methods of MPR,MIP and VR.Results All cases could be diagnosed accurately,and images could clearly show the spatial struc-tures and its relations of the feeding arteries,draining vein and aneurysmal sac.Conclusion MSCT post-processing technique of PAVM without contrast is able to make a precise diagnosis,and to show the configuration of PAVM,which does not need contrast medium and acquirelow radiation dose.

Clostridium difficile colonization and/or infection during infancy and the risk of childhood allergic diseases / 소아과

PURPOSE: The gut microbiota can influence several diseases through immune modulation; however, the exact role of microbes such as Clostridium difficileand the relationship between microbiota colonization and allergic diseases are not well known. This study aimed to determine the relationship between C. difficilecolonization and/or infection (CDCI) during infancy and allergic diseases during early childhood. METHODS: Infants 1–12 months of age presenting changes in bowel habits for more than 2 weeks were enrolled in this study. After dividing them into 2 groups according to the presence and absence of C. difficile, the risk of allergic disease development during childhood was identified and compared. RESULTS: Sixty-five patients were included in this study; 22 (33.8%) were diagnosed with CDCI. No significant differences were observed in baseline characteristics between the C. difficile-positive and -negative groups except for antibiotic exposure (22.7% vs. 60.5%, P=0.004). Compared to the C. difficile-negative group, the risk of developing at least one allergic disease was higher in the C. difficile-positive group after adjusting other variables (adjusted odds ratios, 5.61; 95% confidence interval, 1.52–20.74; P=0.007). Furthermore, food allergies were more prevalent in the C. difficile-positive group (P=0.03). CONCLUSION: CDCI during infancy were associated with a higher risk of developing allergic diseases during early childhood. These results suggest that CDCI during infancy might reflect the reduced diversity of the intestinal microbiota, which is associated with an increased risk of allergic sensitization. To identify the underlying mechanism, further investigation and a larger cohort study will be needed.

Lack of Efficacy of Ulinastatin Therapy During Cardiopulmonary Bypass Surgery / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>It was believed that inflammatory response induced by cardiopulmonary bypass (CPB) was blamed for complications after cardiac surgery. To improve the outcome, many pharmacological interventions have been applied to attenuate inflammatory response during CPB. The objective of this study was to investigate the effect of ulinastatin (urinary trypsin inhibitor [UTI]) on outcome after CPB surgery.</p><p><b>METHODS</b>Totally, 208 patients undergoing elective valves replacement between November 2013 and September 2014 were divided into Group U (n = 70) and Group C (n = 138) based on they received UTI or not. Categorical variables were compared between groups using Fisher's exact test, and continuous variables using unpaired Student's t-test or Mann-Whitney U-test. One-way analysis of variance and Dunnett's or Tukey's tests were used to compare values at different time points within the same group. The risk of outcomes was estimated and adjusted by multivariable logistic regression, propensity scoring, and mixed-effect models for all measured variables.</p><p><b>RESULTS</b>Both the serious complications in total, including death, acute lung injury, acute respiratory distress syndrome and acute kidney injury, and the other complications, including hemodialysis, infection, re-incubation, and tracheotomy were similar between the two groups (P > 0.05). After adjusted by multivariable logistic regression and the propensity score, UTI still cannot be found any benefit to improve any outcomes after cardiac surgery. Also, no statistical differences with regard to duration of postoperative mechanical ventilation, the length of Intensive Care Unit and hospital stays (P > 0.05).</p><p><b>CONCLUSION</b>UTI did not improve postoperative outcomes in our patients after cardiopulmonary bypass surgery.</p>
