Anti-inflammatory and hepatoprotective effects of total flavonoid C-glycosides from Abrus mollis extracts

The aim of this study was to evaluate the anti-inflammatory and hepatoprotective effects of the total flavonoid C-glycosides isolated from Abrus mollis extracts（AME）. In the anti-inflammatory tests, xylene-induced ear edema model in mice and carrageenan-induced paw edema model in rats were applied. The hepatoprotective effects of AME were evaluated with various in vivo models of acute and chronic liver injury, including carbon tetrachloride（CCl4）-induced hepatitis in mice, D-galactosamine（D-GalN）-induced hepatitis in rats, as well as CCl4-induced hepatic fibrosis in rats. In the acute inflammation experiment, AME significantly suppressed xylene-induced ear edema and carrageenan-induced paw edema, respectively. In the acute hepatitis tests, AME significantly attenuated the excessive release of ALT and AST induced by CCl4 and D-GalN. In CCl4-induced hepatic fibrosis model, AME alleviated liver injury induced by CCl4 shown by histopathological sections of livers and improved liver function as indicated by decreased liver index, serum ALT, AST, TBIL, and ALP levels and hydroxyproline contents in liver tissues, and increased serum ALB and GLU levels. These results indicated that AME possesses potent anti-inflammatory activity in acute inflammation models and hepatoprotective activity in both acute and chronic liver injury models. In conclusion, AME is a potential anti-inflammatory and hepatoprotective agent and a viable candidate for treating inflammation, hepatitis, and hepatic fibrosis.

The extract used resulted in mean %WMI of 94.44%, as observed when the worms were put in lukewarm buffer for 30 min after exposure to different treatments. The mean mortality index of the sample was 0.95. The lethal concentration （LCs0）was 0.11 mg·mL ^-1. Cell lines were exposed to concentration of 100 μg·mL^-1 of extract for 48 h, which reduced the viability of these cell lines. The same plant extract also showed 55.58% DPPH radical scavenging activity.     

Evaluation of anti-inflammatory and anti-arthritic property of ethanolic extract of Clitoria ternatea

Objective: Clitoria ternatea is a well-known bioactive plant used to treat several inflammatory ailments in Ayurvedic system of medicine in India. The present investigation aimed to determine the anti-inflammatory and anti-arthritic activity of ethanolic extract of Clitoria ternatea roots (EECT) in animal models. Methods: The anti-inflammatory activity of the EECT was evaluated by carrageenan and histamine-induced paw edema. Results: EECT showed a significant reduction in mean paw edema volume in both carrageenan and histamine-induced inflammation. The efficacy of EECT in rheumatoid arthritis was tested against Freund’s complete adjuvant (CFA) induced arthritic models in Wistar rats. The anti-arthritic effect of EECT was determined by systematic scoring of arthritis symptoms and measuring paw edema. A considerable decrease in paw diameter was observed in the EECT (200 and 400 mg/kg) and diclofenac (10 mg/kg) treated groups after day 7. Diclofenac (10 mg/kg) and EECT (400 mg/kg) showed a significant reduction in paw diameter from day 14 compared with CFA control (P < 0.001). The anti-arthritic activity was also confirmed from the altered biochemical, haematological (Hb, RBC and WBC) and anti-oxidant parameters (SOD, MDA, CAT, and GSH). EECT (400 and 200 mg/kg) also showed a marked inhibition of joint destruction. Conclusion: This study provides a pharmacological rationale for the traditional use of C. ternatea against inflammation and rheumatoid arthritis in India.

Characterization and evaluation in vivo of baicalin-nanocrystals prepared by an ultra-sonic-homogenization-fluid bed drying method简

AIM： To improve the absorption and bioavailability of baicalin using a nanocrystal （or nanosuspension） drug delivery system. METHODS： A tandem, ultrasonic-homogenization-fluid bed drying technology was applied to prepare baicalin-nanocrystal dried powders, and the physicochemical properties of baicalin-nanocrystals were characterized by scanning electron microscopy, photon correlation spectroscopy, powder X-ray diffraction, physical stability, and solubility experiments. Furthermore, in situ intestine single-pass perfusion experiments and pharmacokinetics in rats were performed to make a comparison between the microcrystals of baicalin and pure baicalin in their absorption properties and bioavailability in vivo. RESULTS： The mean particle size of baicalin-nanocrystals was 236 nm, with a polydispersity index of 0.173, and a zeta potential value of-34.8 mV, which provided a guarantee for the stability of the reconstituted nanosuspension. X-Ray diffraction results indicated that the crystallinity of baicalin was decreased through the ultrasonic-homogenization process. Physical stability experiments showed that the prepared baicalin-nanocrystals were sufficiently stable. It was shown that the solubility of baicalin in the form of nanocrystals, at 495 ug·mL-1, was much higher than the baicalin-microcrystals and the physical mixture （135 and 86.4 ug·mL- 1, respectively）. In situ intestine perfusion experiments demonstrated a clear advantage in the dissolution and absorption characteristics for baicalin-nanocrystals compared to the other formulations. In addition, after oral administration to rats, the particle size decrease from the micron to nanometer range exhibited much higher in vivo bioavailability （with the AUC（0-t） value of 206.96 ± 21.23 and 127.95 ± 14.41 mg·L-1·h-1, respectively）. CONCLUSION： The nanocrystal drug delivery system using an ultrasonic-homogenization-fluid bed drying process is able to improve the absorption and in vivo bioavailability of baicalin, compared with pure baicalin coarse powder and micronized baicalin.     

Qingkailing injection for the treatment of acute stroke： a systematic review and Meta-analysis

OBJECTIVE: To evaluate systematically the clinical efficacy and safety of Qingkailing(QKL) injection in the treatment of acute stroke.METHODS: Searches for randomized controlled trials into acute stroke treated with QKL injection were performed in the China National Knowledge Infrastructure Database, China Science and Technology Journal Database, Wan fang Database,Chinese Biomedical Literature Database, PubMed and Cochrane Library, from January 1979 to March2013. Two reviewers independently retrieved the RCTs and extracted the information. The Cochrane risk of bias method was used to assess the quality of the included studies, and a Meta-analysis was conducted with Review Manager 5.2 software.RESULTS: A total of 13 studies with 1110participants were included. The quality of the studies was generally low. The Meta-analysis indicated that the combined use of QKL and Western Medicine was significantly superior to control group therapy in terms of the total effective rate. The relative risk(RR) in the acute cerebral hemorrhage(ACH) sub-group was 1.17 [95%confidence interval(CI)(1.08, 1.26), P=0.0001]. In the acute cerebral infarction(ACI) sub-group, RR was 1.27 [95% CI(1.14, 1.42), P0.0001], and in the ACH and ACI mixed sub-group, RR was 1.34 [95% CI(1.20,1.50),P0.00001]. Additionally, QKL promoted the absorption of hematoma [mean difference(MD)=﹣3.73, 95%CI(﹣4.48, ﹣2.98), P0.000 01],decreased neurological damage in ACI [MD=﹣5.60, 95% CI(﹣8.50, ﹣2.70), P=0.0002] and ACH[MD= ﹣ 4.08, 95% CI( ﹣ 8.00, ﹣ 0.16), P=0.04],promoted the recovery of awareness [RR=1.56, 95%CI(1.09, 2.21), P=0.01] and reduced the whole blood viscosity coefficient [MD=﹣ 0.75, 95% CI( ﹣1.47, ﹣0.03), P=0.04]. There were no adverse drug reactions reported in the included studies.CONCLUSION: Based on this systematic review,QKL combined with conventional therapy was effective compared with control treatment.However, because the articles used in the study were not of high quality, further studies should be conducted into the efficacy and safety of QKL in treating acute stroke.

CONCLUSION： Moxibustion has an analgesic effect and increases hypothalamic POMC and PDYN mRNA expression levels and plasma β-EP content inRArats.Theanalgesiceffectinmoxibustiongroup ⅡisbetterthanthatinmoxibustiongroupⅠ.     

Effects of feeding tyrosine and phenylalanine on the accumulation of phenylethanoid glycosides to Cistanche deserticola cell suspension culture

AIM： To investigate the effects of feeding phenylalanine （Phe） and tyrosine （Tyr） on the accumulation of total phenolic compounds and four phenylethanoid glycosides （PeGs） to a cell suspension culture of the parasitic plant Cistanche deserticola.METHOD： A cell suspension culture of C. deserticola was established and precursors of different concentrations were fed. In each group, the cell was sampled at the 24^th day after inoculation. The content of total phenolic compounds and four PeGs compounds were determined using the Folin-Ciocalteu method and an HPLC method, respectively.RESULTS： In the Phe fed cells, the maximum PeGs yield was achieved when Phe was fed at 1.5 mmol·L^-1 and the yield reached 1.13 times the control cell concentration. In the Tyr fed cells, the maximum yield of PeGs was 1.60 times of control when 0.75 mmol·L^-1 Tyr was fed to the cells. Furthermore, it was found that the salidroside yield was 4.01 times of control group when 5 mmol·L^-1 Tyr was fed.CONCLUSION： Tyr is a better precursor for PeGs accumulation compared with Phe, and the rate limiting enzymes might be involved in the Tyr branch.     

Hypercoagulability in cancer patients grouped by syndromes differentiated with the theory of abnormal hilit in traditional Uyghur medicine

OBJECTIVE： To investigate the relationship in ma- lignant-neoplasm patients of hypercoagulability between syndromes differentiated with the theory of abnormal hilit in traditional Uyghur medicine（TUM）. METHODS： A total of 248 patients with malignant tumors were enrolled. Based on the theory of TUM they were divided into two groups： abnormal Sav- da and abnormal Non-Savda（including abnormal Khan, abnormal Sepra and abnormal Belghem types）; fifty healthy volunteers were selected as controls. Platelet（PLT）, prothrombin time（PT）, plas- ma fibrinogen（FIB）, thrombin time（TT）, activated partial thromboplastin time（aPTT） and D-Dimer（D-D） were measured in both groups. RESULTS： Compared with the control and abnor-mal Non-Savda groups, in the abnormal Savda group the PLT count increased（P0.05）, the PT was lengthened（P0.01）, and the FIB significantly in- creased（P0.01）. D-Ds in the three groups were sig- nificantly different（P0.05）. No significant differ- ence was found inTT and aPTT values（P0.05）. CONCLUSION： Hypercoagulability existed in pa- tients with malignant tumors in the different types of TUM syndromes, especially in the abnormal Sav- da group; this was characterized by increased blood viscosity, platelet aggregation and thrombo- sis. D-D appears to be a significant predictor for the therapeutic effect of TUM in relation to malignant tumor therapies.     

Effects of Chaiyuwendan decoction on endocannabinoids levels in adipose tissue of rats with chronic stress-induced depression

OBJECTIVE： To investigate how Chaiyuwendan de- coction（CWD） affects endocannabinoid levels in the adipose tissue of depressed rats. METHODS： Twenty-four male Sprague-Dawley rats were randomly divided into four groups with six rats in each. One group was randomly selected as the control group. The remaining three groups were subjected to chronic stress to induce depression. Groups were randomly assigned as a model group, CWD group, and amitriptyline group. CWD was giv- en to the CWD group once a day from the second day of modeling. The amitriptyline group was ad- ministered amitriptyline intragastrically（10 mg/kg） once a day. After treatment for 21 days, body weight and fat weight were measured and the lev- els of N-arachidonoylethanolamine（AEA）, 2-arachi- donoylglycerol（2-AG）, and N-palmitoylethanol- amine（PEA） in adipose tissue were determined with liquid chromatography-mass spectrometry.RESULTS： Compared with the control group, body weight, fat weight, AEA, and PEA were significantly lower, and 2-AG was higher, in the model group（P 0.05, P0.01）. Compared with the model group, body weight, fat weight, the AEA, and PEA levels were significantly higher, and 2-AG level was signifi- cantly lower in the CWD group（P0.05）. However, the levels did not differ significantly between the CWD group and the amitriptyline group. CONCLUSION： CWD could regulate the levels of AEA, 2-AG, and PEA in rats with depression induced by chronic stress.
