AIM To investigate the roles of Cl- channels in Ca2+ influx induced by activaion of al- adrenoceptor subtypes in transfected-CHO cells. METHODS The effects of drugs on ?1A、?1B and ?1D- AR-induced Ca2+ influx were investigated with Fura2 fluorescence technique. RESULTS The ?1A-AR- induced Ca2+ influx was inhibited by furosemide(2 .5 ~ 10 M?mol?L- 1 )and SK&F96365(5- 15 ?mol?L- 1 ) in a concentration- dependent manner respectively; The ?1B-AR-induced Ca2+ influx could also be inhibit inhibited by NFA(2. 5 ~ 10 ?mol? L-1 ), whereas the alD AR-induced Ca2+ influx was only suppressed by NFA. In ?1B-CHO cells, Adr-triggered Ca2+ influx could be further inhibited by NFA or furosemide after the maximal inhibition by SK&F96365;SK&F96365 could further inhibit Ca2+ influx which had been inhibited by NFA or furosemide. In ?1A-CHO cells, Adr-triggered Ca2+ influx could be further inhibited by SK&F96365 after had been inhibited by furosemide; furosemide could not further inhibite Ca2+ influx which had been inhibited by S&F96365. CONCLUSION There are different characteristics of CI- channels related to ?1A、 ?1B and ?1D-AR-induced Ca2+ influx.

ObjectiveTo explore the mechanism of Montelukast combined with Huang Qi Huai in the treatment of asthma.MethodsForty male Sprague-Dawley (SD) rats were chosen and randomly divided into five groups:control group (Control),model group (Model),Montelukast group (MK),Huang Qi Huai group (H),Montelukast + Huang Qi Huai group (MK + H),each group has 8 rats.The other four groups except the control group were built to chronic rat asthma model.The treatment groups were administered intragastrically with Montelukast,Huang Qi Huai and Montelukast + Huang Qi Huai respectively.All animals were sacrificod; plasma and bronchoalveolar lavage fluid (BALF) and superior lobe of right lung tissues were collected.Superior lobes of right lung tissues were used to measure the expression of IL-17 in lung tissue by immunohistochemistry.The airway inflammation was analyzed by histochemistry staining with H.E.Total cells score and differential score in BALF were counted.The levels of IL-17 in the plasma and BALF were measured by Enzyme-linked immunosorbent assay (ELISA).ResultsCompared with the control group,the degree of inflammatory cell around the airway in the model group were significantly higher (P ＜ 0.05).Compared with group model,the degree of inflammatory cell around the airway in the Group MK,group H and group MK + H were significantly ameliorated ( P ＜0.05).Compared with Group MK,the degree of inflammatory cell around the airway in group MK + H was significantly ameliorated ( P ＜O.05),the expression of IL-17 in lung tissues was significantly lower ( P ＜0.05),the numbers of total cells and the concentration of IL-17 in plasma and BALF were decreased too ( P ＜0.05).Correlation analysis showed that the level of IL-17 in the plasma and BALF was positively correlated with the level of IL-17 in the lung tissue( P ＜ 0.05 ).ConclusionsCombined Huang Qi Huai adjuvant Montelukast treatment of asthmatic rat further reduced the concentration of IL-17 in the plasma and BALF,reduced the expression of IL-17 in lung tissue,improved the airway inflammation.Down regulation the expression of IL-17 was probably one of the mechanisms of anti-inflammatory.

Aquaporins (AQP), abundant in diversity, are the member of the major intrinsic proteins (MIPs) family with extraordinary ability to transport water, and thus, play important roles in modulation of water relations in plants. The recent advances in classification, structural characteristics, and physiological functions during plant growth and development as well as the various regulation modes of the activity and the effects of several abiotic stresses (water stress and salt stress) and phytohormones (ABA, GA and ethylene) on the gene expression of AQP were reviewed.

BACKGROUND:Col agen type II and proteoglycan loss are two most obvious manifestations of cartilage damage in the onset of osteoarthritis. Changes in col agen type II and proteoglycan as the main components of cartilage matrix directly lead to cartilage degeneration and subsequently result in osteoarthritis. How to reverse or prevent the development of this process becomes the focus of medical research. OBJECTIVE:To observe the effect of warming yang and benefiting marrow recipe on the expression of col agen type II and proteoglycan in the articular cartilage of knee osteoarthritis rabbits as wel as to further explore the mechanism underlying chondrocyte protection. METHODS:Ninety-six New Zealand rabbits, aged 9 months old, male and female, were selected to prepare osteoarthritis models in extension position using cast immobilization method, and were randomly divided into four groups:blank group (untreated), model group (simple modeling), Chinese medicine group (intragastric administration of extracts of warming yang and benefiting marrow recipe, 24 mL/kg/d) and western medicine group (intragastric administration of glucosamine hydrochloride, 24 mL/kg/d). Intragastric administration was done once a day for 6 weeks. RT-PCR technology was used to observe the effect of warming yang and benefiting marrow recipe on the expression of col agen type II and proteoglycans in the articular cartilage, and pathological examination was also done. RESULTS AND CONCLUSION:The cartilage surface was smooth in the blank group and Chinese medicine group, with uniform toluidine blue staining, but in the model group and western medicine group, the cartilage surface was rough and the toluidine blue staining was extremely uneven with obvious loss of surface and middle layer dying. The expressions of cartilage proteoglycan and col agen type II in the model group were significantly lower than those in the blank group (P<0.01) as wel as in the Chinese medicine group and western medicine group (P<0.05). In addition, the expressions of cartilage proteoglycan and col agen type II in the Chinese medicine group were higher than those in the western medicine group (P<0.05). These findings indicate that the recipe of warming yang and benefiting marrow can enhance the expressions of col agen type II and proteoglycan, which can maintain the normal col agen phenotype and protect the articular cartilage.
