Objective To construct an oncolytic adenovirus CNHK600-IL24, and to observe the in vivo effects of CNHK600-IL24 in treating breast cancer. Methods The IL-24 gene was cloned into adenovirus shuttle vector SG502-△CR2, and CNHK600-IL24 was obtained by cotransfection of SG502-INSIL24 and pPE3 plasmids and subsequent recombination in 293 cells. Based on the establishment of the athymic mice model of breast cancer in situ and imitated metastatic breast cancer by injection in the vena caudalis and the left artrium, we administered the virus by the tail vein. We used the optical imaging in vivo system to monitor the effects. Results The oncolytic adenovirus CNHK600-IL24 was correctly constructed and confirmed by restriction DNA sequence analysis and PCR. The titer of CNHK600-IL24 reached 1.9 ×1010pfu/ml. Establishing athymic mice model of breast cancer in situ, the volume and photon number of the tumors in the control group was significantly larger than those of the CNHK600-IL24 group( P ＜0. 05). The tumor had conspicuous necrosis after the treatment of CNHK600-IL24. There was noticeable apoptosis of the tumor cells. Immunohistochemistry showed the expression of IL-24 and the Hexon protein in the tumor cells.In athymic mice model of imitated metastatic breast cancer by infusion into the vena caudalis, most of the mice in the control group died before 38 days, the mice of the CNHK600-IL24 group survived significantly longer(P ＜0. 05 ). Using athymic mice model of imitated metastatic breast cancer by infusion in the left artrium, the optical imaging in vivo system showed obvious difference between the control group and the CNHK600-IL24 group. Conclusions The high-titer oncolytic adenovirus CNHK600-IL24 was successfully constructed and purified. The oncolytic adenovirus had obvious antitumor effect on breast cancer.

Objective To evaluate the value of contrast-enhanced ultrasound in superficial lymphadenopathy. Methods Ninty-four superficial enlarged lymph nodes were studied by 2-dimensional, color Doppler ultrasound, and contrast-enhanced ultrasound. Then the contrast-enhanced images were analyzed by Philips Q-LAB software. All the results were compared with pathological diagnosis. Results For the 94 superficial lymph nodes examined,44 were benign,33 were metastases and 17 were lymphomas. The sensitivity, specificity,and accuracy of contrast-enhanced images were 84% ,74% and 790//oo respectively. Contrast-enhanced ultrasound examination showed intense homogeneous enhancement in 39 of 44 benign lymph nodes; high or low homogeneous enhancement in 25 of 33 and 7 of 33 in metastases respectively;intense homogeneous, and scarce enhancement in 6 of 17 and 9 of 17 in lymphomas respectively. Time-intensity curves showed that compared with metastasis lymph nodes and lymphomas, benign lymph nodes had higher peak intensity and larger area under the curve (P<0.01). Conclusions The diagnosis accuracy was significant increased when contrast-enhanced ultrasound was test against conventional ultrasound. The character of contrast agent enhancement and Q-LAB time-intensity curves provide valuable diagnosis information for differential diagnosis of benign,metastasis lymph nodes and lymphomas.

Objective To investigate the relationship of Maternal-fetal interface local cytokine GM-CSF and its receptor with the occurrence of early spontaneous abortion. Methods From August 2009 to December 2011,we collected 30 villi tissue samples with artificial abortion and 30 villi tissue samples with spontaneous abortion. At the same time, we collected 30 villi tissue samples with artificial abortion and 30 decidua tissue samples with spontaneous abortion,and 30 decidua tissue samples with spontaneous abortion. The human chorionic gonadotropin ( HCG) was detected by radioimmunoassay in every group. The expressions of granulocyte-macrophage colony-stimulating factor (GM-CSF) and granulocyte-macrophage colony-stimulating factor receptor (GM-CSFR ) were detected by Immunohistochemical staining and Western Blot in the villi tissue and decidua tissue in every group. Results The concentration of HCG in the spontaneous abortion group was lower than that in the artificial abortion group ( <0.05) . The protein expressions of GM-CSF and GM-CSFR were found in villus and deciduas tissues in both groups. The protein expression levels of GM-CSFR in the villus tissues were higher in spontaneous abortion group than those in artificial abortion group ( <0.05), the protein expression of GM-CSF was upregulated, but there was no statistically significant difference between two groups. In deciduas tissues, the protein expressions of GM-CSF and GM-CSFR were upregualted in spontaneous abortion group ( <0.05) . Conclusions The suitable concentrations of GM-CSF and GM-CSFR in decidua tissue maintain the pregnancy continued. However,the higher concentrations of GM-CSF and GM-CSFR in the decidua tissue may be one of reasons of spontaneous abortion.

Objective To systematically assess the relation between angiotensin-I converting enzyme(ACE) gene insertion/deletion (I/D) variation and type 2 diabetic nephropathy (T2DN) onset risk among Chinese population.Methods The related literatures were retrieved from the China National Knowledge Infrastructure (CNKI) and Wanfang Data until June 1st,2016.The RevMan 5.0 was used to conduct the statistical analysis.The merge OR value and corresponding 95% confidence interval(95%CI) were used to assess ACE gene I/D polymorphism and T2DN onset risk.Results Totally 29 papers with 4 357 subjects were included according to the inclusion and exclusion standard,including 2 208 cases of DN and 2 149 cases of T2DM without DN.Meta analysis showed that compared with ACE gene I/D polymorphism I allele,D allele could significantly increase the risk of T2DM patients suffering from DN,the OR value and corresponding 95%CI were 1.44(1.25,1.66);the gene analysis showed that ACE gene I/D polymorphism loci were significantly correlated with DN onset risk in the Asian population.The corresponding relative onset risk OR and 95%CI were 1.42(1.15,1.76) and 1.75(1.46,2.10) in the dominant and recessive genetic model.The Begg′s test showed that the included data had no obvious publication bias existence.Conclusion ACE gene I/D polymorphism is closely correlated with the onset risk of T2DN,and D allele might be a risk genetic factor for DN occurrence in the patients with T2DM.

Objective To explore effects of different urostomy education paths in patients undergoing cystectomy with creation of a urostomy.Methods 42 cases of patients after radical cystectomy with creation of a urostomy were randomly divided into the control group and the observation group. The control group received the original version of urostomy education path, while observation group received modified version of urostomy education path. Knowledge of urostomy, stoma bag replacing skills, and length of hospital stay were compared between the two groups. Results Patients in the observation group who received modified version of urostomy education path showed better knowledge of urostomy and skills of replaceing stomy bag, as well as shorter hospital stay (P<0.05).Conclusions Our modified version of urostomy education path results in improved self-care ability among patients and their family members. It suggests the urostomy education needs constant innovation and enhancement on the basis of practice.

To investigate the value of renal resistive index (RRI) in early predictor and discriminator of severe acute pancreatitis (SAP)-related acute kidney injury (AKI). Methods A retrospective observational study was conducted. SAP patients complicated with AKI (within 1 week of onset) and admitted to intensive care unit (ICU) of Ruijin Hospital Shanghai Jiaotong University School of Medicine from January 2016 to June 2019 were enrolled. The RRI within 24 hours admission was measured. Clinical data such as acute physiology and chronic health evaluation Ⅱ(APACHEⅡ), heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), intra-abdominal pressure (IAP), arterial blood lactate (Lac), oxygenation index (PaO2/FiO2), base excess (BE), serum creatinine (SCr), urine output, norepinephrine (NE) and RRI were collected. Within 24 hours and 7 days after ICU admission, patients were grouped according to AKI classification criteria of Kidney Disease: Improving Global Outcomes (KDIGO), and the differences of relevant parameters were statistically analyzed. Influence factors of AKI grading were screened by Logistic regression analysis. Pearson correlation analysis was used to analyze the correlation between RRI and other parameters. The predictive value of RRI for AKI classification was analyzed by receiver operating characteristic (ROC) curve. Results A total 57 patients were included, with an average age of (54.6±13.5) years old, and APACHEⅡscore of 21.8±5.6. Within 24 hours, the number of patients suffered from stage 1-3 AKI were 19 (33.3%), 18 (31.6%) and 20 (35.1%), respectively. On day 7, the number of patients suffered from stage 0-3 AKI were 21 (36.9%), 8 (14.0%), 9 (15.8%) and 19 (33.3%), respectively. The higher APACHEⅡ score, CVP, IAP, Lac, NE dosage and RRI were found in the group with higher AKI grades, especially in the group with stage 3 AKI on day 7. RRI of patients with stage 3 AKI was significantly higher than that of patients with stage 1 and 2 AKI within 24 hours (0.74±0.04 vs. 0.65±0.05, 0.68±0.05, both P < 0.05). Similarly, RRI of patients with stage 2 and 3 AKI were significantly higher than that of patients with stage 0 and 1 AKI on day 7 (0.70±0.04, 0.74±0.04 vs. 0.65±0.05, 0.66±0.05, all P < 0.05). Multivariate Logistic regression analysis showed that RRI was an independent factor of AKI classification [odds ratio (OR) = 3.15, 95% confidence interval (95%CI) = 1.09-9.04, P < 0.05], and IAP and CVP also had significant impacts on AKI grading [OR value was 2.11 (95%CI = 1.16-4.22), 3.78 (95%CI = 1.21-12.90), both P < 0.05]. ROC curve analysis showed that the area under curve (AUC) of RRI for predicting AKI ≥2 stage was 0.87 (P < 0.05); the cut-off ﹥ 0.71, sensitivity was 71% and specificity was 83%. The correlation analysis showed that RRI was positively correlated to a certain extent with IAP and lactic acid (r1 = 0.49, r2 = 0.39, both P < 0.05). Conclusion High RRI on ICU admission was a significant predictor for development of severe AKI during the first week, and RRI can help predict the tendency of AKI in SAP.

Objective To explore the molecular mechanism of Xiaojin Pills in the treatment of breast cancer using an integrated network pharmacology and experimental verification.Methods The chemical components and potential targets of Xiaojin Pills were obtained from TCMSP,TCM-ID,ETCM and SwissTargetPrediction databases.Breast cancer related targets were collected from GeneCards,OMIM and KEGG databases.The overlapped targets were imported into STRING database to analysis a protein-protein interaction(PPI).The key targets of PPI networks were screened based on node topology parameter values through Cytoscape 3.8.0.DAVID database was used to analyze the GO and KEGG pathway enrichment to build drug-chemical components-key targets-signaling pathway network.The breast cancer cell lines MDA-MB-231 and SK-BR-3 were used to study the effects of Xiaojin Pills extract on cell apoptosis,migration and invasion,and to verify the key pathway obtained by enrichment analysis.Results Totally 181 chemical components in Xiaojin Pills were obtained,including quercetin,myricetin,pinocembrin and β-sitosterol.615 potential targets were identified for the anti-breast cancer effects of Xiaojin Pills.After overlapping,170 key targets against breast cancer were identified based on the topological analysis,which included SRC,ERK1/2,AKT1,EGFR,etc.KEGG analysis enriched pathways including pathways in cancer,MAPK signaling pathway,endocrine resistance,PI3K-AKT signaling pathway,EGFR tyrosine kinase inhibitor resistance,apoptosis,and HIF-1 signaling pathway,which may play important roles in the therapeutic effects of Xiaojin Pills against breast cancer.GO enrichment was involved in protein phosphorylation,inflammatory response,negative regulation of apoptosis,and positive regulation of ERK1 and ERK2 cascades.Cell experiments showed that Xiaojin Pills further induced mitochondria-dependent apoptosis by inhibiting the activation of MAPK and PI3K-AKT pathways.At the same time,the expressions of ZO-1 and β-catenin increased,and the epithelial-mesenchymal transformation process was reversed to inhibit the metastasis of breast cancer cells.Conclusion The key targets and signaling pathways of Xiaojin Pills in the treatment of breast cancer are studied through network pharmacology combined with in vitro experiments,which provided a basis for further study of its pharmacodynamic material basis,mechanism of action and clinical application.
