A serumal metabonomics method based on UPLC/Q-TOF-MS was established to investigate the mechanism of Schisandra chinensis to treating diabetic nephropathy. The diabetic model was established by feeding with high-fat and high-sucrose chow and streptozotocin intraperitoneal injection. After intragastric administration for 12 weeks, the content of protein and creatinine in rat urine was detected. The results showed that Schisandra chinensis could reduce the content of protein in urine of diabetic rat ( p<0 . 05 ) and ameliorate the condition of diabetic nephropathy. The serum metabolic profiling was analysed by using UPLC/Q-TOF-MS and partial least squares-discriminated analysis ( PLS-DA) was used for data analysis. The score of PLS-DA showed that there was significant difference among the metabolic profile of control group, model group and Schisandra chinensis group ( WWZ ) . Potential biomarkers of Schisandra chinensis ameliorating diabetic nephropathy were selected by orthogonal partial least squares ( OPLS)-DA model. According to the results of OPLS-DA, the MS/MS data of each compound which provided greater contribution to separation of each group were searched from the HMDB databases. Seven endogenous metabolites were identified as potential biomarkers such as xanthurenic acid, palmitic amide, oleamide, uric acid, 5-hydroxyhexanoic acid, p-cresol sulfate, and p-cresol glucuronide. The results revealed that Schisandra chinensis mainly affected the pathways of tryptophan metabolism, gut microbiota metabolism, purine metabolism and fatty acid metabolism to treating type 2 diabetes mellitus. The gut microbiota metabolism and purine metabolism was an important pathway on diabetic nephropathy.

Objective To explore the relationship and the clinical significance of homeobox gene B1 (HOXB1 )and microRNA-31 75 (miR-31 75)expressions in human glioma.Methods The expression levels of HOXB1 and miR-31 75 in 60 glioma tissues and 1 5 normal brain tissues were analyzed by real-time fluores-cent quantitative PCR (qRT-PCR).Spearman rank correlation analysis was performed to explore the relation-ship between HOXB1 and miR-31 75 in human glioma tissues.The relationship between HOXB1 (or miR-31 75)and clinical pathological characteristics of glioma patients was analyzed.The correlation of HOXB1 (or miR-31 75)and survival rate was calculated by Kaplan-Meier.And COX regression models were used to assess the prognostic factors.Results Compared with normal brain tissues,the expression of HOXB1 was significant-ly decreased in glioma tissues (1 .498 ±0.323 vs.0.946 ±0.588,t =-5.680,P =0.000);and the expre-ssion of miR-31 75 was obviously increased in glioma tissues (1 .008 ±0.355 vs.2.076 ±0.841 ,t =4.274, P =0.000),and HOXB1 expression was negatively correlated with miR-31 75 expression in glioma tissues (r =-0.601 ,P =0.000).HOXB1 expression was related with histologic grade (χ2 =4.848,P =0.028), and miR-31 75 expression was related with histologic grade (χ2 =5.640,P =0.01 8)and Karnofsky score (χ2 =4.785,P =0.029).The results of Kaplan-Meier revealed that there were significant differences in median survival time between HOXB1 (or miR-31 75)high-expression group and HOXB1 (or miR-31 75)low-expression group [HOXB1 :(21 .0 ±4.0)months vs.(7.0 ±0.8)months;χ2 =7.495,P =0.006;miR-31 75:(6.0 ±0.6)months vs.(1 6.0 ±5.8)months;χ2 =9.591 ,P =0.002].COX regression models showed that tumor degree (RR =6.556,95% CI:1 .1 96-35.952,P =0.002),HOXB1 (RR =0.01 8, 95%CI:0.001 -0.31 2,P =0.006)and miR-31 75 (RR =2.098,95%CI:1 .663-7.51 3,P =0.037)were independent prognostic factors for prognosis.Conclusion The HOXB1 expression may be negatively correlated with miR-31 75 in human glioma tissues,and the expression levels of HOXB1 and miR-31 75 are associated with the glioma malignant degree,survival time and prognosis of glioma patients.

Objective To evaluate the application of high-throughput shell vial assay in a clinical laboratory for detection of respiratory viruses from patients with ILI in Guangzhou between January and June, 2009. Methods Six hundred and fifty-two pharyngeal swab specimens were taken from ILI patents. Centrifugation-enhanced shell vials including 4 cell lines (MDCK, Hep-2, LLC-MK2 and MRC-5) were used for culture of respiratory viruses for 2-3 days. The cultures were identified by observation of cytopathic effect (CPE) , hemmaglution or hemmadsorption test as well as immunofluorescence staining. Results A total of 161 swab samples (24.69% ,161/652) were shown to have any one of the 5 common respiratory viruses including influenza A viruses ( 38. 51% , 62/161 ), influenza B virus ( 54. 65% , 88/161 ), parainfluenza viruses (4. 96% , 8/161 ) , adenovirus ( 1. 24% , 2/161 ), and respiratory syncytial virus (0. 62% ,1/161). The turnaround time was 2d for influenza viruses, 3d for adenovirus and parainfluenza viruses respectively. Conclusions (1) The shell vial method was effective, rapid and high throughout for the detection of respiratory viruses in clinical laboratories.(2)Influenza viruses were dominant in the swab samples from patients with ILI in Guangzhou between January and June with the highest appearance in the summer influenza B vires was the most common pathogen in patients with ILI in this study.

Isatis indigotica Fort. (Ban-Lan-Gen) is an herbal medicine prescribed for influenza treatment. However, its active components and mode of action remain mostly unknown. In the present study, erucic acid was isolated from Isatis indigotica Fort., and subsequently its underlying mechanism against influenza A virus (IAV) infection was investigated in vitro and in vivo. Our results demonstrated that erucic acid exhibited broad-spectrum antiviral activity against IAV resulting from reduction of viral polymerase transcription activity. Erucic acid was found to exert inhibitory effects on IAV or viral (v) RNA-induced pro-inflam-matory mediators as well as interferons (IFNs). The molecular mechanism by which erucic acid with antiviral and anti-inflammatory properties was attributed to inactivation of NF-kB and p38 MAPK signaling. Furthermore, the NF-kB and p38 MAPK inhibitory effect of erucic acid led to diminishing the transcriptional activity of interferon-stimulated gene factor 3 (ISGF-3), and thereby reducing IAV-triggered pro-inflammatory response amplification in IFN-β-sensitized cells. Additionally, IAV- or vRNA-triggered apoptosis of alveolar epithelial A549 cells was prevented by erucic acid. In vivo, erucic acid administration consistently displayed decreased lung viral load and viral antigens expression. Meanwhile, erucic acid markedly reduced CD8+cytotoxic T lymphocyte (CTL) recruitment, pro-apoptotic signaling, hyperactivity of multiple signaling pathways, and exacerbated immune inflammation in the lung, which resulted in decreased lung injury and mortality in mice with a mouse-adapted A/FM/1/47-MA(H1N1) strain infection. Our findings provided a mechanistic basis for the action of erucic acid against IAV-mediated inflammation and injury, suggesting that erucic acid may have a therapeutic potential in the treatment of influenza.
