Neurodegenerative diseases are global public health problems that seriously affect the quality of human life. The incidence of neurodegenerative diseases is increasing year by year and there has been no effective treatment. Acanthopanax senticosus is a Chinese medicine for tonifying kidney and has a long medicinal and edible history. It contains many active ingredients such as saponins, coumarins, flavonoids, organic acids and polysaccharides, with pharmacological effects of anti-oxidation, anti-age, anti-inflammation, anti-fatigue and immune regulation. Modern medical studies have found that A. senticosus can act on the central nervous system, and its extracts and active ingredients can improve learning and memory ability, playing vital roles of anti-oxidation, anti-inflammation, anti-apoptosis, antagonizing against amyloid β protein(Aβ) toxicity, modulating neurotransmitter release, signaling pathways and brain energy metabolism, maintaining the structure and function of mitochondria, and epigenetic regulation. It treats neurodegenerative diseases via multiple components, multiple targets, and multiple pathways, with the characteristics of low toxic side effects. This study reviewed the pharmacological reports of A. senticosus on neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease and ischemic stroke in China and abroad in recent ten years, and summarized the active ingredients and the mechanism underlying the neuroprotective effects of A. senticosus. Additionally, the significant advantages of A. senticosus in the treatment of neurodegenerative diseases and the limitations of the reports were discussed from the aspects of traditional Chinese medicine(TCM) theory and modern medical research. This study provided theoretical support for the drug development and clinical application of A. senticosus in treating neurodegenerative diseases and also facilitated the prevention and treatment of neurodegenerative diseases by kidney-tonifying method in TCM.

Leaf blight is the main disease of Asarum. At present, chemical treatment is main measure for disease control, and there is no report on biological control. In order to achieve the biological control of Asarum leaf blight, the biocontrol strains with antagonistic effect on Asarum leaf blight were screened. The rhizosphere bacteria of healthy Asarum plants were isolated by soil dilution method, and the isolated strains were screened by the methods of antagonistic antifungal and fermentation liquid antifungal, then the strains were identified and the control effect in vivo was determined. Abiocontrol bacterial strains S2-31 which with high antagonism to leaf blight was obtained from more than 100 isolated strains. The inhibitory rates of antagonistic antifungal and fermentation liquid antifungal reached 92.47% and 60.56%, respectively. It was identified by morphology and 16 S rDNA sequence analysis, and the strain was identified as Brevibacillus laterosporus. The results of indoor potted experiment showed that the control effect was 79.87%, 71.44% and 66.82% on the 3 rd, 5 th and 7 th day after inoculation, respectively, which indicated that S2-31 could reduce the disease index and control the development of Asarum leaf blight.

To systemically evaluate the efficacy and safety of salvianolate intravenous drip in combination with hydration against contrast-induced nephropathy( CIN),and guide clinical medication. Chinese and English databases( PubMed,EMbase,the Cochrane Library,CBM,VIP,Wan Fang database,CNKI) were retrieved to collect the randomized controlled trials( RCTs) about the efficacy of salvianolate intravenous drip in combination with hydration( trial group) vs routine hydration( control group) in the prevention of contrastinduced nephropathy. The methodological quality of the RCTs was evaluated by using the Cochrane 5. 1. 0 Bias Risks Assessment Tool.The data were extracted and Meta-analysis was conducted by Reviewer Manager 5. 3. Egger's test and non-parametric clipping method were used to evaluate publication bias. A total of 9 RCTs with 2 186 participants were included. RESULTS:: of Meta-analysis showed that the incidence of contrast-induced nephropathy of trial group was significantly higher than that of control group( RR = 0. 46,95% CI[0. 35,0. 59],P<0. 001). Subgroup analysis showed that the incidences of CIN in patients with acute coronary syndrome( ACS) undergoing PCI,in patients with the average age≥65 years,in patients who received mean contrast volume ≥200 m L,in patients with serum creatinine( Scr) ≥ 80 μmol,or in patients who received intraoperative administration of salvianolate or PCI were higher than those in control group,with statistically significant differences( P<0. 05). The experimental group was superior to the control group in improving the indexes of renal function after operation,and the difference was statistically significant( P<0. 05). No study reported the incidence of adverse reactions( ADRs). The funnel plots of the incidence of CIN showed potential publication bias. The results of Egger's linear regression showed that there was certain publication bias. Sensitivity analysis,funnel plot,and " trim and fill" showed that the results of this study were stable and reliable. Salvianolate combined with routine hydration showed definite clinical efficacy in the prevention of contrast-induced nephropathy. However,exact conclusion should be further verified by additional high-quality,multi-centre,and large-scale RCT studies.

OBJECTIVE: Age-related diseases, including neurodegenerative diseases, are associated with oxidative stress and lipid peroxidation, and increase the levels of cholesterol auto-oxidation products such as 7β-hydroxycholesterol (7β-OHC). Thus, it is imperative to identify agents that can prevent 7β-OHC-induced side-effects. METHODS: We evaluated the potential protective effects of Carpobrotus edulis ethanol-water extract (EWe) on murine oligodendrocytes (158N) cultured in the absence or presence of 7β-OHC (20 μg/mL, 24 h). The cells were incubated with EWe (20-200 µg/mL) 2 h before 7β-OHC treatment. Mitochondrial activity and cell growth were evaluated with the MTT assay. Photometric methods were used to analyze antioxidant enzyme [catalase (CAT) and glutathione peroxidase (GPx)] activities and the generation of lipid and protein oxidation products [malondialdehyde (MDA), conjugated diene (CD), and carbonylated proteins (CPs)]. RESULTS: Treatment with 7β-OHC induced cell death and oxidative stress (reflected by alteration in CAT and SOD activities). Overproduction of lipid peroxidation products (MDA and CDs) and CPs was also reported. The cytotoxic effects associated with 7β-OHC were attenuated by 160 μg/mL of EWe of C. edulis. Cell death induced by 7β-OHC treatment was ameliorated, GPx and CAT activities were restored to normal, and MDA, CD, and CP levels were reduced following C. edulis extract treatment. CONCLUSION These data demonstrate the protective activities of C. edulis EWe against 7β-OHC-induced disequilibrium in the redox status of 158N cells, indicative of the potential role of this plant extract in the prevention of neurodegenerative diseases.

Peach brown rot, caused by Monilinia fructicola, is one of the most serious peach diseases. A strain belonging to the Actinomycetales, named Streptomyces blastmyceticus JZB130180, was found to have a strong inhibitory effect on M. fructicola in confrontation culture. Following the inoculation of peaches in vitro, it was revealed that the fermentation broth of S. blastmyceticus JZB130180 had a significant inhibitory effect on disease development by M. fructicola. The fermentation broth of S. blastmyceticus JZB130180 had an EC₅₀ (concentration for 50% of maximal effect) of 38.3 µg/mL against M. fructicola, as determined in an indoor toxicity test. Analysis of the physicochemical properties of the fermentation broth revealed that it was tolerant of acid and alkaline conditions, temperature, and ultraviolet radiation. In addition, chitinase, cellulase, and protease were also found to be secreted by the strain. The results of this study suggest that S. blastmyceticus JZB130180 may be used for the biocontrol of peach brown rot.

A transgenic maize event ZD12-6 expressing a Bacillus thuringiensis (Bt) fusion protein Cry1Ab/Cry2Aj and a modified 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) protein G10 was characterized and evaluated. Southern blot analysis indicated that ZD12-6 is a single copy integration event. The insert site was determined to be at chromosome 1 by border sequence analysis. Expression analyses of Bt fusion protein Cry1Ab/Cry2Aj and the EPSPS protein G10 suggested that they are both expressed stably in different generations. Insect bioassays demonstrated that the transgenic plants are highly resistant to Asian corn borer (Ostrinia furnacalis), cotton boll worm (Helicoverpa armigera), and armyworm (Mythimna separata). This study suggested that ZD12-6 has the potential to be developed into a commercial transgenic line.
