[Objective] To sum up researches on components, pharmacological actions and toxicity of Polygonum multiflorum Thunb(Heshouwu). [Method] The research reference about Heshouwu in CNKI, VIP and PUBMAD database is col ected and calssified to three aspects on components, pharmacological actions and toxicity.[Result]①On components:Heshouwu contains stilbene, lecithin, anthraquinone, flavonoids, tannin and trace elements. The stilbene and anthraquinone are the mainly active components. Producing area, growth years, harvest time and processing methods are factors affecting the content of the components such as TSG in Heshouwu; Macroporous adsorption resin is the main separation method for preconcentration of TSG and anthraquinone constituents; ② On pharmacological actions and toxicity: Heshouwu has effects of hypolipidemic and liver protection, antioxidative, anti-osteoporosi, hpyerglycemic, antidepressive and antibiosis, the hypolipidemic and liver protection are the main effects which have been studied more. A reversible liver injury which displays as abnormal liver function parameter and bile metabolic disorder would be induced if the Heshouwu is administrated with a large dosage for long term. The possible components which would induce the toxicity in Heshouwu are tannin and anthraquinone, and the anthraquinone is the component with double effects of toxicity and therapy which should be considered in clinical application. [Conclusion]Reducing lipid and protecting liver is the main pharmaceutical function of the herb. As a commonly used Chinese herb for liver protection, the studies on alcoholic hepatic injury protection of Heshouwu may be a point for the researchers to focus on. The comparison studies on hypolipidemic and liver protection between Hesouwu and its processing products, and the correlations between components and pharmacological actions are worth study further.

The basement membrane (BM) is crucial in regulating the physical and biological activities of esophageal epithelial cells which attach to the underlying BM. In order to simulate the natural construction of BM, we prepared the fibrous scaffolds using biodegradable polylactide (PLA) and silk fibroin (SF) as the materials via electrospinning technology. BM's proteins containing collagen (IV), laminin, entactin and proteoglycan were extracted from porcine esophagus and coated on the eletrospun fibers. Morphology, mechanical strength, biodegradability and cytocompatibility of the coated and uncoated scaffolds were tested and evaluated using scanning electron micrography, mechanical test system, immunofluorescence assay and western blotting with CK14 as the primary antibody. The fibrous scaffold PLA or PLA/SF, generated from the present protocol had good formation and mechanical and biodegradable properties. After coating with BM's proteins, the scaffold could enhance the growth and differentiation of esophageal epithelial cells, which would contribute to remodel and regenerate the tissue engineered epithelium and further contribute to engineer the whole esophagus in future.

Objective Plasma phospholipid metabolism analysis was employed to investigate plasma metabolic profile of acute renal graft rejection in order to find potential disease biomarkers and reveal its pathophysiological changes.Methods Selected 33 patients which did renal transplant in our hospital during 2009 to 2010,named preoperative group.14 patients were diagnosed as acute graft rejection,and 19 patients were non-acute graft rejection.Then use ultra performance liquid chromatography (UPLC) coupled with quadrupole time of flight mass spectrometry (qTOF-MS) to establish the metabolic fingerprint in those patients.The date was preprocessed with software Markerlynx,and analyzed with partial least squares discriminant analysis (PLS-DA),and data from conventional laboratory techniques were used for assessing renal function.Results In the plasma of renal transplant patients,seventeen biomarkers were discovered:creatinine,four sphingomyelins (SM),nine phosphatidylcholines (PC),three lysophosphatidylcholine (LPC).While the creatinine was increased,the others were reduced obviously.Conclutions UPLC-qTOF-MS based metabonomics can analyze the plasma phospholipid metabolism in patients with renal transplantation,reveal the law of phospholipids metabolic changes in the process of acute rejection.The levels of plasma phosphatidylcholine's esterlysis and fatty acids' β-oxidation are increased.The immunosuppressive therapy can reduce the activity of phospholipase,inhibit the level of plasma phosphatidylcholine's esterlysis and fatty acids' β-oxidation,which restraines the development of acute rejection after renal transplantation.Therefore it may be a promising new technology in diagnosing acute renal graft rejection after renal transplantation.

Objective To investigate the intensive atorvastatin therapy on B7-H4 in peripheral blood monocytes of patients with unstable angina PCI undergoing percutaneous coronary intervention. Methods 80 patients with unstable angina were randomized to pretreatment with intensive dose (80 mg/day ,n = 40) and conventional dose(20 mg/day,n=40)of atorvastatin. Peripheral blood were subsequently obtained prior to PCI,and 18 ~ 24 h after PCI. Peripheral blood serum level of IL-4,IL-10 and IFN-γ were quantified using enzyme-linked immunosorbent assays. Fluorescence-based quantitative real-time PCR was used to measure levels of periph-eral blood monocytes B7-H4 mRNA. Results Levels of IL-10 ,sB7-H4 and B7-H4 mRNA increased in patients of both groups after PCI. The increase in intensive dose group is more significant (P < 0.05). IL-4 and IFN-γ decreased in patients of both groups after PCI. The decrease in intensive dose group is more significant (P <0.05). Conclusion Intensive dose atorvastatin treatment improve post-PCI immune inflammation in patients with unstable angina,possibly by promoting the expression of B7-H4 in peripheral blood monocytes.

To compare the microcalorimetric fingerprint profiles of Lonicerae japonicae Flos (Lj.F) and Lonicerae Flos (L.F), microcalormietry was applied to find the heat change regularity of Bacillus shigae (B. shigae) metabolism affected by Lj.F and L.F (we choose Lonicera macranthoides Hand.-Mazz in this paper) with different concentrations. The thermogenic curves and thermodynamics parameters were investigated as evaluation index, and then the date of experiment was studied by similarity analysis. All the results indicated that the Lj.F and Lonicera macranthoides Hand.-Mazz (L.m.H-M) significantly impacted the microbial growth and had good similarity in its inhibitory activities. The combination approach of chemical analysis with bioassay was developed and employed to ensure the safety and efficacy of Chinese herbal medicines.

Objective To study the rational daily administration times of Yinchenhao Decoction (YCHD) when it was used to treat experimental jaundice in rats based on pharmacodynamics/pharmacokinetics model.MethodsRats were modeled by 4％ 1-naphthylisothiocyanate (75 mg/kg) for 48 h,then YCHD was drenched with doses of 0.324 g/kg (extract,calculated with the clinical dosage) once,0.162 g/kg twice,and 0.108 g/kg thrice a day,respectively.The total bile and the flow rate of bile were observed after the first administration; Blood samples collected from the orbital sinus at different intervals were used to investigate the levels of liver enzymes (ALT and AST) and bilimbins (TBIL and DBIL),and determine the concentration of 6,7-dimethoxycoumarin (DME) in the plasma using UPLC at the same time,then we obtained the time-effect and time-dose curves.The rational daily administration times of YCHD when treating experimental jaundice were determined based on the comprehensive analysis of time-effect and time-concentration relationships.ResultsWithin 10 h the total bile of rats which were administered once daily (G1) was I.65 and 1.33 times higher than that of twice and thrice (G2 and G3) a day,respectively,and the four biochemical indexes (TBIL,ALT,DBIL,and AST) of Gl decreased faster than those of G2 and G3 (P ＜ 0.05).On the other hand,the blood drug level of DME when administrated once daily could maintain at a higher level for a longer time,and its Cmax and AUC0→t were higher than those of G2 and G3,which might be the main reason why its effect was the most significant.ConclusionIt is more appropriate to administrate once daily when YCHD is used to treat jaundice.
