Objective: To explore the mechanism of Chinese medicinal therapy for nourishing blood and softening Gan in treating senile pruritus through observing the impact of Guishen Zhiyang Recipe (GZR) on serum levels of stem cell factor (SCF) and dynorphin (DYN) in patients suffered from the disease of blood-deficiency and Gan-hyperactive syndrome type (BDGH)., Methods: Sixty patients with senile pruritus were equally randomized into two groups, the patients in the treated group (33 cases) were treated by GZR, and those in the control group (28 cases) were treated by Fuyang Granule, all for 8 weeks. Changes of symptoms and skin lesions as well as blood levels of SCF and DYN were observed before and after treatment., Results: Three patients were rejected from the treated group. Twenty patients in the treated group were cured after treatment, the cure rate being 66.7%, which was significantly higher than that in the control group (10 patients, 35.7%, P < 0.05). Levels of SCF and DYN in the treated group significantly lowered after treatment (all P < 0.01), and were lower than those in the control group (P < 0.05 and P < 0.01, respectively)., Conclusion: GZR shows favorite effect in treating senile pruritus of BDGH type and it may be achieved by regulating SCF and DYN levels to improve the pruritus associated inflammatory media.

Objective: To observe the clinical effect of TCM treatment for dissolving phlegm and dispelling stasis (DP-DS) on acute cerebral infarction (ACI) and its influences on plasma protein C and S and soluble thrombomodulin (TM)., Methods: One hundred and twenty-two patients were randomly assigned to two groups, the treated group (62 cases) and the control group (60 cases). They were all treated with the conventional treatment, and DP-DS treatment was given to the treated group additionally. The treatment course was 14 days. The changes in scores of TCM syndrome and neurofunction impairment (NIHSS), levels of plasma protein C (PC), protein S (PS) and TM before and after treatment in the two groups were observed., Results: The total effective rate of TCM syndrome in the treated group was higher than that in the control group (P= 0.00). After treatment, NIHSS in the two groups was significantly different (P=0.00), and the score in the treated group was superior to that in the control group (P = 0.00). NIHSS score and levels of PC and PS were improved in both groups (P = 0.024, 0.028), and the improvement of PC in the treated group was superior to that in the control group respectively (P = 0.049). But no significant change of TM was shown after treatment., Conclusion: TCM DP-DS treatment shows significant effect in improving TCM syndrome and neurofunction impairment of the patients with acute cerebral infarction, and raise the levels of PC and PS.
