AIM To observe the inhibitory effects of tricin on the airway inflammation in low concentration LPS induced asthma mice.METHODS The model of asthma mice with airway inflammation was induced by low concentration LPS plus OVA.There were four groups:blank control group,asthma model group,tricin treatment group and dexamethasone (positive drug) treatment group.The levels of inflammatory factors,including NO,TNF-α and IL-1β,in bronchoalveolar lavage fluid (BALF) were detected by ELISA;the pathology of lung tissue was observed by HE staining;the mRNA and protein expressions of TLR4,MyD88 and NF-κB p65 in alveolar macrophages were detected using real-time quantitative PCR (RT-PCR) and Western blot.RESULTS Tricin could significantly decrease the levels of NO,TNF-α and IL-1β in BALF of asthma mice and improve lung inflammation.It could also down-regulate the relative mRNA and protein expressions of TLR4,MyD88 and NF-κB p65.CONCLUSION Tricin has inhibitory effects on airway inflammation in asthma mice,whose mechanism may be related to the intervention of TLR4/MyD88/NF-κB pathway.

Cold-heat problem is one core of traditional Chinese medicine theory. This paper summarizes the experimental research related to the biological basis of cold-heat essence in cold-heat syndrome, cold-heat body constitution and cold-heat property of Chinese herbs. In view of the classical physiological and biochemical indices, gene expression, protein expression and metabolic differences, differences in cold-heat syndrome or cold-heat constitution are mainly based on neurotransmitter, thyroid function, sex hormone, cyclic nucleotide system, and energy metabolism relating to the corresponding gene and protein expression. Furthermore, this paper analyses the change of correlation indices that accompany with a dynamic development process of "constitution-syndrome-herbal intervention", implying that the research of biological basis of cold-heat essence has turned from single index to multiple indices, and from dispersion research to system research.

Methods: With the commercially available package and at 40℃ ± 2℃, RH (75% ± 5%) for six months,the stability of WMG was inspected. Guinea pig skin sensitization test, rabbit skin irritation test and cell toxicity test were used to investigate the safety. Results:Compared to the results of 0 month, there was no difference in the sample character, containing paste percentage, adhesion, shape, weight difference and all theindices in TLC identification. Cell toxicity test showed that WMG had slight cytotoxicity. Guinea pig skin sensitization test and rabbit skin irritation test indicated that the grade of skin reaction was zero and the primary stimulus index of skin tissues was also zero. Conclusion:The quality of WMG is stable and the production preparation technology is feasible. Moreover, it is safe in transder-mal administration.

Objective:This study aimed to identify the morphology of mast cells by using a modified toluidine blue staining scheme,so as to provide a powerful reference for the experimental basis research of mast cells.Methods:Bone marrow-derived mast cells were induced in vitro.After 4 weeks,the cells were collected,fixed,and stained.Mast cells were fixed at different temperature during different time.The optimum condition was determined by comparing the effects of toluidine blue staining.Results:Bone marrow cells were induced to differentiate into mast cells by SCF and IL-3 in vitro.When mast cells were stained with modified toluidine blue staining,the staining effect was better.Mast cells were round or oval and the cell membrane was complete and the cytoplasm was filled with a large number of purple particles.Conclusion:In this study,we successfully applied a modified toluidine blue staining method to mast cells cultured in vitro.The results showed that the condition at 37 ℃ full fixation with staining could reduce the degeneration of mast cells.This method was easy to operate with good stability.It was suitable for the morphological observation of mast cells cultured in vitro.

Ginsenoside Rb3 (GRb3) is one of the main components in plasma of Panax quinquefolius Saponin of stem and leaf (PQS), which can be into human plasma. Previous studies have found PQS has estrogen-like vascular protective effects. In the present study, we investigated the estrogen-like protective effect of GRb3 on oxidative stress and dysfunction of endothelial cells induced by oxidized low-density lipoprotein. The activities of SOD, NOS and the contents of MDA in the cell lysate were examined by enzyme method or spectrophotometry. The NO and ET-1 concentrations in the cell culture supernatant were measured by ELISA method. The iNOS and eNOS mRNA expression were measured by real time RT-PCR, while the phosphorylation levels of Akt was measured by Western blotting. The results showed that GRb3 could enhance the activity of SOD, reduce the content of MDA, increase the level of NOS, NO, ET-1 and iNOS mRNA expression while decrease the eNOS mRNA expression and the phosphorylation level of Akt. These effects were blocked by estrogen receptor antagonist ICI182780. GRb3 can play a role in protecting vascular endothelial cells by estrogen receptors, the protective mechanism is similar to 17-β estrodiol.
