High performance liquid chromatography-time-off-flight mass spectrometer (HPLC-TOFMS) technology coupled with partial least squares discriminant analysis (PLS-DA) processed by SIMCA-P software was applied to investigate serum endogenous metabolites alternations of valsartan in spontaneous hypertension rats (SHR). And MetPA platform was used to connect identified potential biomarkers in corresponding metabolic pathways to find possible therapeutic mechanism of valsartan. Valsartan significantly declined the blood pressure of SHRs (P < 0.05) at fourth week. The metabolic profiling significantly changed and four metabolites involved in G protein-coupled pathway were identified. Metabolomics is able to detect holistic and microcosmic alternations in organism, so as to elucidate therapeutic mechanism of drugs.

Thirty SHRs were obtained randomly to hypertension, model group, captopril group and Qingre jiangya capsule group. Ten Wistar rats were used as control group. The hippocampus tissue was removed to explore the damage of spontaneously hypertensive rats (SHR) and the protective effect of Qingre jiangya capsule after continuously administered for 14 days. And then the data were processed by principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA). The research results revealed captopril group was significantly different from the other three groups. The classification of other three groups is also very clear after captopril group removed. This suggested that Qingre jiangya capsule could improve the overall metabolism compared with captopril. Four metabolites were identified: dimethylglycine, glycerophosphocholine, aldosterone and noradrenaline. Hypertension hippocampus damage may mainly be expressed in tyrosine metabolism, aldosterone-regulated sodium, vascular smooth muscle contraction reabsorption, and Qingre jiangya capsule could reverse the hippocampus tissue damage of SHR.

Objective To profile the phenotype and pathogens of cutaneous and mucous mycoses in a dermatology outpatient clinic in Nanchang region. Methods A review was performed to assess cutaneous and mucous mycoses diagnosed in the dermatology outpatient clinic of Dermatology Hospital of Jiangxi Province from 2006 to 2008. The relationship of clinical phenotype and pathogens to season, patients' age and gender was analyzed. Results A total of 7251 cases were collected, and the ratio of male to female patients was 2.3: 1. The most prevalent mycoses included tinea cruris (2702, 37.1%), pityriasis versicolor (1505, 20.8%) and tinea manus (727, 10.0%). In total, 4953 fungal strains were isolated from all the patients except for those with pityriasis versicolor, of them, Trichophyton rubrum accounted to 69.9%, Candida to 20.4%, and Trichophyton violaceum to 4.5%. Season, patients' age and gender were found to be associated with clinical phenotypes and pathogens of mycoses. Conclusions In the dermatology outpatient clinic of Nanchang region, tinea cruris is the most common superficial fungal disease, with the predominant pathogen being Trichophyton rubrum. Trichophyton violaceum is the primary pathogen of tinea capitis, which is different from other reports.

To reveal the colonization characteristics in host of endophytic biocontrol bacteria NJ13 isolated from Panax ginseng, this study obtained the marked strain NJ13-R which was double antibiotic resistant to rifampicin and streptomycin through enhancing the method of inducing antibiotic. The colonization characteristics in ginseng and its biocontrol efficiency against Alternaria spot of ginseng in the field were studied. The results showed that the strain could colonize in root, stem and leaf of ginseng and the colonization amount was positive correlated with inoculation concentration. Meanwhile, the strain could infect and then transfer in different tissues of ginseng The colonization amount of strain in roots and leaves of ginseng increased first and then decreased. However, the tendency of colonization amount of strain in stems was ascend at first and then descend slowly, and was more than that in roots and leaves along with time, which had a preference to specific tissue of its host. In field experiment, the endophytic bacteria NJ13 was proved to be effective in controlling Alternaria leaf spot of ginseng. The biocontrol efficiency of fermentation broth at the concentration of 0.76 x 10(8) cfu x mL(-1) reached 75.62%, which was close to the controlling level (73.06%) of 0.67 mg x L(-1) 50% cyprodinil WG.

Objective: To explore the points selection pattern of acupuncture for sleep apnea syndromes by data mining technique. Methods: Clinical literature about acupuncture therapy for sleep apnea syndromes was derived from China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), PubMed and Science Direct between the time that databases were created and March 25th,2017. Relevant excel database was established and descriptive studies and association rules were analyzed. Results: The most frequently used point was Lianquan (CV 23) and the most frequently used meridian was the Stomach Meridian. The analysis of association rules showed that the clinical choice of acupuncture points was highly correlated, among which the combination of the highest degree of confidence and the highest degree of support was Shenmen (HT 7) and Sishencong (EX-HN 1); Lieque (LU 7), lianquan (CV 23) and Zhaohai (KI 6). Conclusion: Acupuncture treatment of sleep apnea syndromes has specific selection rules of points, providing certain references for clinical and scientific research.

To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) and TACE alone for hepatocellular carcinoma (HCC), Pubmed, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Datebases were searched for the randomized controlled trials (RCTs) and retrospective cohort studies from the establishment of the databases to January 2014. The bibliographies of the included studies were searched, too. After study selection, assessment, data collection and analysis were undertaken, we performed this meta-analysis by using the RevMan5.2 software. Seventeen studies involving 1116 patients met the inclusion criteria with 530 treated with RFA-plus-TACE and 586 with TACE alone. The results of meta-analysis showed that the combination of TACE and RFA was obviously associated with higher 1-, 2-, and 3-year overall survival rates (OR1-year=3.98, 95% CI 2.87-5.51, P<0.00001; OR2-year=3.03, 95% CI 2.10-4.38, P<0.00001; OR3-year=7.02, 95% CI 4.14-11.92, P<0.00001) than TACE alone. The tumor complete necrosis rate in patients treated with TACE and RFA was higher than that of TACE alone (OR=13.86, 95% CI 8.04-23.89, P<0.00001). And there was a significant difference in local recurrence rate between two different kinds of treatment (OR=0.24, 95%CI 0.14-0.44, P<0.00001). Additionally, combination of TACE and RFA was associated with higher complete tumor necrosis rates than TACE mono-therapy in the treatment of HCC. However, RFA plus TACE was found to be associated with a lower local recurrence rate than TACE monotherapy. TACE-plus-RFA treatment was associated with a higher response rate (RR) than the TACE-alone treatment (OR=3.90, 95% CI=2.37-6.42, P<0.00001). TACE-plus-RFA treatment did not differ from the TACE-alone treatment in terms of stable disease (SD) rate (OR=0.38, 95% CI=0.11-1.26, P=0.11). Meta-analyses showed that the combination of RFA and TACE was associated with a significantly lower progressive disease (PD) rate (OR=0.15, 95% CI=0.05-0.43, P=0.0005). The rate of AFP reducing or returning to normal in serum in RFA plus TACE group was obviously lower than TACE alone group (OR=4.62, 95% CI 2.56-8.34, P<0.00001). The effect of TACE plus RFA for HCC is better than TACE mono-therapy. The combined therapy can elevate the patients' overall survival rate, tumor necrosis rate and the rate of AFP reducing or returning to normal in serum and decrease local recurrence rate, PD rate compared with TACE alone.
