Engelhardia Leschen. ex Blume (Juglandaceae) is native to southern and southeastern Asia and used to be traditional medicines and health tea. Hitherto, a large amount of chemical constituents had been isolated from genus Engelhardia and more pharmacological effects were found due to the presence of the second metabolites. There have been few comprehensive reports about Engelhardia plants especially the chemical constituents by now. The traditional usage of Engelhardia plants were for treating cold fever, detoxication, rheumatism, diarrhea, obesity, gastrointestinal problem and so on. While the modern pharmacological activities showed antioxidant activity, anti-ischemia/reperfusion injury, anticancer activity, anti-inflammatory activity, immunosuppression activity, antidiabetic activity, antitubercular activity and so on. In this review, constituents of this genus would be introduced and classified by structures, the pharmacological effects of which would be described as well.

Objective To screen the extraction process of Wenfei Jiangzhuo Recipe (WJR) by pharmacodynamics and acute toxicity test, and to optimize it by orthogonal experiment to determine the best extraction process of WJR. Methods Acute toxicity test was carried out on different WJR samples. The improvement of learning and memory of vascular dementia (VD) rats was used as the efficacy index, and the results of the acute toxicity and efficacy experiments determined the best process plan. Using contents and yield rate as index, orthogonal test was used to screen the amount of solvent, extraction time and extraction times. Results The results of acute toxicity test showed that all mice survived without obvious toxicity. The results of pharmacodynamic test showed that the best extraction plan of WJR was as follows: Extracting white prepared lateral root of Aconite, Codonopsis Radix, and Glycyrrhizae Radix et Rhizoma Praeparata cum Melle with water, and Notoginseng Radix et Rhizoma, Zingiberis Rhizoma, and wine processing Rhei Radix et Rhizoma with ethanol. The optimized extraction technology were as follows: The former were 10-fold water reflux extraction for three times and 1 h each time, with white prepared lateral root of Aconite first reflux 2 h; The latter were 6-fold 70% ethanol reflux extraction three times and each time 1.5 h. Conclusion WJR can significantly improve the learning and memory ability of VD model rats. The optimized extraction conditions are reasonable and feasible, and can provide the basis for the subsequent development of WJR.

Objective: Our aim was to investigate the polymorphism and forensic meaning of the Y-chromosomal loci DYS390 and DYS389Ⅰ/Ⅱ in Han nationality in Liaoning Province. Methods: By amplifying these loci with polymorase chain reaction (PCR) followed by polyacrylamide gel electrophoresis and silver staining, the allele frequencies of these loci among 98 unrelated men of Han nationality were investigated. Results: Five alleles with different frequencies from 0.010 to 0.480 were detected of DYS390， and three alleles with different frequencies from 0.224 to 0.439 were detected of DYS 389Ⅰ. Locus DYS 389Ⅱ was detected in five alleles and the frequencies ranged from 0.020 to 0.367. The probability discrimination of these loci were 0.637, 0.644 and 0.723. These loci were found to generate at least 31 different haplotypes and the power of discrimination was 0.948. Conclusion: The loci DYS390 and DYS389Ⅰ/Ⅱ are very important when detect mixed samples, especially in deficiency cases of paternity test.

OBJECTIVETo discuss the protective effect of Mailuoning injection on ischemia/reperfusion (I/R) injury in rats and its mechanism.

METHODHealthy male adult Sprague-Dawley (SD) rats were randomly divided into the sham operation group, the model group, the edaravone (3 mg x kg(-1)) control group, and Mailuoning high, middle and low-dose groups (4, 2, 1 mL x kg(-1)), with 10 rats in each group, and administered with drugs through tail intravenous injection. The middle cerebral artery occlusion (MCAO) was adopted to establish the rat ischemia/reperfusion model. After the ischemia for 2 h and reperfusion for 24 h, the pathological changes in neurovascular units (NVU) of brain tissues at the ischemia side was observed by HE staining. The expressions of glialfibrillary acidic protein (GFAP) and ionized calcium-binding adaptor molecule 1 (Ibal) were detected by the immunohistochemical method. The expressions of tumor necrosis factor-alpha (TNF-alpha), interleukin 1beta (IL-1beta), vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) were detected by the western blotting technique.

RESULTMailuoning injection could significantly improve the pathological changes in cortical penumbra brain tissue UVN of (I/R) rats, reduce the number of GFAP and Ibal positive cells, and significantly decrease the expressions of TNF-alpha, IL-1beta, VCAM-1 and ICAM-1 of brain tissues of I/R rats.

CONCLUSIONMailuoning injection shows an obvious protective effect on UVN of I/R rats. Its mechanism may involve the inhibition of the activation of astrocyte and microglia and the secretion and expression of various inflammatory factors.

In order to provide scientific basics for exploitation and sufficient application of Dendrobium officinale leaves resources, the phenol-sulfuric acid method was applied to determine the polysaccharide content. The monosaccharides were derivated by PMP and the derivatives were identified by HPLC-DAD-ESI-MS(n) and the contents of mannose and glucose were determined simultaneously. Similarity evaluation system for chromatographic fingerprint of traditional Chinese medicine (2004A) was employed to generate the mean chromatogram and similarity analysis of the samples was carried out. The results demonstrated that polysaccharide content, monosaccharide compositions and composition ratio had an obvious difference between stems and leaves. The polysaccharide content of stems was higher than that of leaves. Monosaccharide composition in leaf was significantly different from that in stem. The polysaccharide from stems was composed of mannose and glucose, however the polysaccharide of leaves was acid heteropolysaccharide and was mainly composed of five monosaccharides, including mannose, galacturonic acid, glucose, galactose and arabinose. The similarity value of the 14 batches was above 0.9, indicating that similarity of fingerprints among different samples was high. The study can provide evidence for expanding the medicinal parts of D. officinale.
