At present, the objective of cutting and pruning Cistanche deserticola is to harvest in successive years and enhance the harvesting yield and quality of C. deserticola in the process of the artificial cultivating C. deserticola. An experiment was conducted focusing on cutting and pruning C. deserticola in artificial forests of Haloxylon ammodendron drip-irrigated with saline water at the hinter-land of the Taklimakan desert, according to different growth stages and lengths. The results were following: (1) The effect of cutting on C. deserticola was similar to that of pruning, which resulted in three kinds of morphological types, not related to the bloom and size of C. deserticola. (2) The growth forms were diversified after pruning. Among them, there had sprouting new body, died or maintaining life with no sprouting, mildewed on its surface layer, etc. However, some of new bodies were sprouting from the lower part of the old body. The death rate of bloomed C. deserticola was higher than that of the underground, and the death rate of the 40 cm in stubble height for C. deserticola was higher than those with the stubble height of 20 cm and 5 cm. (3) Most of the diameter of living C. deserticola after pruning was increasing, but some of them changed little. (4) The mildew and rot of C. deserticola and the broken of the roots of the H. ammodendron and the fallen of the point of the inoculated when it was dug, which would cause the death of the C. deserticola. On the other, the yield-increasing effect and the economic benefit of the techniques of the pruning of Cistanche would need further research and evaluate. Therefore, the application of this technique needs to be cautious.

OBJECTIVETo explore the therapeutic effects and mechanisms of Zhubi capsule on adjuvant arthritis (AA) in rats.

METHODThe model of rat was induced by intradermal injection of CFA. The perimeter of ankle joint was measured at different time points. Con A-induced splencyte proliferation was examined by MIT assay and the expression of IL-1, IL-6 in synovium was determined by immunohistochemical method.

RESULTAfter the preventive administration of Zhubi capsule (5.2, 2.6, 1.3 g x kg x d(-1), x 25 d), it was found that Zhubi capsule significantly inhibited the primary and secondary ankle joint swelling. The increased Con A-induced splencyte proliferation reaction and the activated IL1, IL-6 expression of AA rat were suppressed by the treatment with Zhubi capsule.

CONCLUSIONZhubi capsule has a therapeutic effect on AA rats, and its mechanism is related to the immunoregulative function.

To prepare the derivatives of salicylic acid-g-chitosan and study their synergistic and complementary actions, the synergism of anti-inflammatory action of the derivatives was investigated with the experiments of xylene-induces mice ear edema, the analgesic activities by the tartaric emetic-induced mice twist test and the hot-plate test, and the complementary effects between salicylic acid and chitosan through morphological changes of stomach mucous membrane of rat, separately. The anti-inflammatory activities of salicylic acid-g-chitosan derivatives for anti-inflammatory activities were more potent than that of salicylic acid and chitosan and dexamethasone cream in external use, and more potent than that of aspirin orally. However, immediate analgesic activity of the derivatives was lower than that of aspirin and persistent activity was similar as that of aspirin. And the stomach mucous membrane morphology change of the derivatives was much milder than that of aspirin. The salicylic acid grafted chitosan derivatives showed synergistic and complementary effect on the anti-inflammatory and analgesic activities and so on.
