Journal of China Pharmaceutical University 2009;40(4):342-347
Aim: To establish an analytical method to study the chemical components in Zhizi-Gancao-Chi(ZGC) decoction, and investigate its anti-depressant effect. Methods: An LC-PDA-MS/MS method was established and applied. The separation was performed on an ODS C_(18) column (250 mm ×4. 6 mm, 5 μm) with a gradient elu-tion. The mobile phase consisted of water/acetic acid( 1 %, v/v) and methanol. The main components were identi-fied according to the UV and MS. The anti-depressant effect was evaluated with mice tail-suspension test and forced swimming test. Results: The components of the ZGC decoction were separated isolated and ten of them were identified. These compounds are classified to iridoid glycosides, flavonoids and triterpene saponins. In addi-tion, its anti-depressant effect was observed for the first time. Conclusion: The LC-PDA-MS/MS method can ef-fectively separate and identify the components of ZGC decoction, which has significant anti-depressant effect. The relationship between the chemical component and its anti-depressant effect needs further study.

Objective To compare the effects and complications of lumboperitoneal shunt ( LP ) and ventriculoperitoneal shunt ( VP ) in the treatment of post?traumatic hydrocephalus. Methods Eighty patients with post?traumatic hydrocephalus treated in the neurosurgery department of Zhangjiagang Hospital of Traditional Chinese Medicine from March 2014 to March 2010 were retrospectively analyzed. The patients were randomly divided into two groups,40 patients treated with LP were assigned into the LP group and 40 patients undergone VP treatment were seen as the VP group. All patients were followed up for 1 year to investigate and compare the symptom improvement rate,neurological deficit score and the incidence of complication of the two groups. Results The total effective rate of hydrocephalus disappearance in the LP group was 41. 50% ( 37/40) and 87. 50%( 35/40) in the VP group. The difference between the two groups was not statistically significant (χ2=0. 556,P=0. 456);the neurological deficit scores before treatment in the LP group and VP group were (28. 35±8. 64) points and (29. 13±7. 98) points,there was no significant difference between the two groups (t=0. 419,P=0. 676) . The difference in the scores of neurological deficit after treatment in the LP and VP group was not statistically significant ( (19. 32±5. 34) points vs. (21. 62±4. 86) points,t=1. 480,P=0. 143),the average scores of neurological deficits in the two groups were significantly better than those before treatment ( t=5. 623, 5. 084,P<0. 001 ) . There was no significant difference in the average score of improvement of urinary incontinence between the two groups before and after treatment ( t=0. 376,1. 265,P>0. 05) ,the average score of urinary incontinence improvement after treatment in both groups were better than those before treatment ( t=4. 891,5. 370,P<0. 001) . In the LP group,the incidence of bleeding,infection,shunt related complications and shunt abnormality were all 2. 50% ( 1/40 ) , the overall complication rate was 10. 00%, the incidence of bleeding,infection,shunt related complications and shunt abnormality in the VP group were 7. 50% (3/40), 10% ( 4/40 ) , 5% ( 2/40 ) 10%, ( 4/40 ) , the overall complication rate was 32. 50%, there was significant difference between the two groups (χ2=6. 050,P=0. 014) . Conclusion LP and VP have significant curative effect on the treatment of post?traumatic hydrocephalus,but the overall incidence of LP complication after 1 year is significantly lower than that of VP,and is worth popularizing widely in clinical practice
