There are reports about the chemical compounds of Ciwujia herbs, but with no study report about the chemical material basis of Ciwujia injection (CWJI). In this study, LC-MS(n) and LC-Q-TOF-MS techniques were adopted for a qualitative analysis on phenylpropanoids in CWJI. The Ultmate XB-C18 column (4.6 mm x 250 mm, 5 microm) was adopted and eluted with the mobile phase of 0.5% formic acid-water and acetonitrile, with the flow rate at 0.8 mL x min(-1) and the column temperature at 20 degrees C. Based on the data of high-resolution and multi-stage MS, control products and literatures, altogether 54 phenylpropanoids were identified in Ciwujia Injection, including 34 phenylpropanoids, 16 ligans and 4 coumarins. Among them, 28 were reported for the first time in Ciwujia, and 14 compound structures were identified in comparison with the control products. The method established in this study could be used to simply and rapidly identify phenylpropanoids in CWJI. The findings provide scientific data for defining the chemical material basis of CWJI.

Xuefu Zhuyu decoction (XFZYD) is a famous traditional Chinese medicine (TCM) formula, is widely used in the treatment of cardiovascular and cerebrovascular diseases in China over one hundred years. But its effect on antioxidant and drug-metabolizing enzymes are unknown. This study was to observe the effects of Xuefu Zhuyu decoction (XFZYD) on the activities of antioxidant and drug metabolism enzymes (DMEs) in liver of rats. Male SD rats, treated with XFZYD at the dosage of 3.51, 7.02 and 14.04 g x kg(-1) per day for 15 days, serum were collected, tissue fluid, cytosols and microsomes isolated from liver tissues were prepared by centrifugation according to the standard procedure, the activities of antioxidant enzymes and drug-Metabolizing Enzymes were determined by UV-V is spectrophotometer. In serum, the activities of AST was not significantly affected by the treatment with XFZYD, at the high- est dose, the levels of ALT, Cr and BUN were significantly decreased (P < 0.05). GPX were significantly increased at the dose of 7.02, 14.04 g x kg(-1) (P < 0.05), CAT were significantly increased at the highest dose (P < 0.05). T-SOD was not significantly af- fected by this treatment. In the liver tissue, GPX was significantly increased at the dose of 3.51, 7.02 g x kg(-1) (P < 0.05), GST, CAT and T-SOD were not significantly affected following this treatment. In cytosols, GST was significantly increased at the dose of 3.51 g x kg(-1) (P < 0.05), T-SOD was remarkable induced at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05). In microsomes, XFZYD had no significant effect on Cytochromeb5, NADPH-Cytochrome P450 reductase, CYP3A, CYP2E1 and UGT, XFZYD significantly in- duced GST at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05), and the level of GSH were significantly increased by XFZYD at the dose of 3.51, 7.02 and 14.04 g kg(-1) (P < 0.05). These findings suggest XFZYD can induce the activities of GPX, CAT, SOD, GST and increase GSH level in liver of rats, which indicate XFZYD may have detoxification and antioxidant functions.

Objective To study the effect of low intensity laser irradiation on wound healing and the expression of transforming growth factor beta-1 (TGF-β1) and interleukin beta-1 (IL-1β) in wounded tissue.Methods Steam was used to scald 60 BALB/c mice.They were then randomly divided into a laser group and a control group with 30 in each group.The wounds in the laser group were irradiated with a low-intensity He-Ne laser,while the control group was given the same treatment except that the instrument was turned off.The wound healing rate was calculated,and the full wound thickness was measured and a reverse transcription polymerase chain reaction (RT-PCR) was used to detect the expression of TGF-β1 and IL-1β right after the scalding and 1,3,7 and 14 days later.Results Seven and 14 days later,the wound healing rates in the laser group were (51.48 ± 5.89) ％ and (73.96 ± 7.25) ％,respectively.Compared with the control group at the same time points,the difference was statistically significant.In the laser group the expression of TGF-β1 had increased significantly at days 1 and 3,then increased to a maximum at day 7.It was significantly greater than in the control group at all three of those time points.At day 14 the expression of TGF-β1 in the laser group was significantly lower than in the control group.The expression of IL-1 β in the laser group had decreased significantly at days 1 and 3,and gradually reduced to a minimum at day 7.It was significantly lower than in the control group at all three of those time points.Conclusion Low intensity He-Ne laser irradiation can accelerate wound healing after scalding,at least in mice.Its effect may be related to its regulation of the expression of IL-1 β and TGF-β1.

Objective To explore the mechanism of Zibu Piyin Recipe (ZBPYR) on spleen yin deficiency diabetes-associated cognitive disorder (DACD). Methods The rats were randomly divided into control group, diabetes mellitus (DM) group, spleen yin deficiency group, spleen yin deficiency DM group and spleen yin deficiency DM+ZBPYR group (treatment group). Type 2 DM models were established by high-fat food feeding and low dose STZ intraperitoneal injection for 4 weeks. Then the classical compound method was used to construct spleen yin deficiency rat models by improper diet, over exertion and yin fluids exhaustion. The treatment group was given ZBPYR by gavage for 15 days, and the other groups were given the same amount of normal saline. Then cerebral cortex, hippocampus, stomach and liver were obtained and the changes of protein expression of PDHE1α in them were observed by Western Blot. Results The protein expression of PDHE1αin cortex of DM group and spleen yin deficiency DM group were lower than control group (P<0.05). PDHE1α expression of treatment group in cortex and stomach increased more significantly than spleen yin deficiency DM group (P<0.05). The expression of PDHE1α protein showed no significant difference among all groups in hippocampus and liver. Conclusion ZBPYR improved spleen yin deficiency DACD by regulating PDHE1αin cortex and stomach.
