Traditional Chinese medicine Curcuma Zedoary ( E'Zhu) contains essential oil, curcuminoid and other effective constituents, with such pharmacological actions as anti-platelet aggregation, lowing blood lipid, anti-oxidation and anti-inflammation. In recent years, studies have showed that certain extracts and chemical components of E'Zhu could mitigate myocardial cell mitochondria injury and protect vascular endothelium by enhancing heme oxygenase-1 activity, inhibit nuclear factor NF-kappaB, target genes interleukin-associated kinase-1 (IRAK-1), tumor necrosis factor receptor-6 (TRAF-6) and vascular cell adhesion molecule-1 (VCAM-1), reduce inflammatory infiltration, and inhibit growth factor-induced smooth muscle cells (SMCs) proliferation and migration by impacting oxidation of cellular phosphatases. Due to its different functions in vascular endothelial cells and smooth muscle cells, E'Zhu has been applied in drug-eluting stents, with a potential effect in preventing in-stent restenosis and thrombogenesis. In this paper, studies on pharmacological effects and mechanisms of extracts and main chemical constituents from E'Zhu in preventing vascular restenosis were summarized.

Objective To study the influence of low-iodine diet on the expression of homeobox gene Nkx-6.1 and Nkx-6.2 in rat cerebrum tissue, and to explore the possible molecular mechanism of cerebrum development retardation caused by low-iodine. Methods Twenty female Wistar rats were randomly equally divided into two groups: low-iodine group and control group, both fed with low-iodine diet as low as 13.66 μg/kg determinated by spectrophotometry in Tianjin Institute of Endocrinology and the former with deionized water, the later 200 μg/L potassium iodate. Thyroid hormone level was detected using chemiluminescence immunoassay 3 months later and they were mated with male rats normally fed. Rats of 16-day pregnancy, new-born and 20th days old were detected the content of Nkx-6.1 and Nkx-6.2 mRNA in the cerebrum tissue by real-time fluorescence quantitative PCR 0.61), (3.28±0.80)pmol/L] were lower than the control group[(1.04±0.06), (39.42±14.68)nmol/L, (4.83±0.33), day pregnancy, new-born and 20th days old of control group was (1.90±0.23)×10-3,(1.86±0.40)×10-4, (1.11± 0.27)×10-4(F=827.58, P<0.01), Nkx-6.1 mRNA expression level gradually decreased along with aging(all P<0.05). The intra-group difference was significant (F=297.25, P<0.01) and the Nkxr.1 mRNA expression level during 16 days of pregnancy was the highest(P<0.01). It was higher in the control group than in the low-iodine group during 16 days of pregnancy (t=10.14, P<0.01) as well as in the low-iodine group than in the in 16-day pregnancy, new-born and 20th days old of control group was respectively(1.03±0.19)×10-2, (1.33± 0.10)×10-3, (8.79±0,87)×10-3, and that of low-iodine group was (0.31±0.03)×10-2, (1.53±0.13)×10-3, (7.51±0.86)×10-2. The intra-group difference was significant(F=1293.02,1065.83, all P<0.01). Nkx-6.2 expression level during 20th days old was the highest(P<0.01) and that of newborn was the lowest(P<0.01). The Nkx6.2 mRNA expression level in control group were higher than the low-iodine group during 16-day pregnancy and 20th days old(t=14.35, 4.05, all P<0.01). It was higher in the low-iodine group than in the control group during newboru(t=4.78, P<0.01). Conclusions The difference in the expression of Nkx-6.1 and Nkx-62 is highly related to the brain development retardation caused by low-iodine.

To investigate the absorption kinetics of Cu B-SDC/PLC-MMs in rat different intestinal segments and compared with the absorption of Cu B suspension. The in vitro everted gut sacs model was established to study the absorption characteristics of Cu B-SDC/ PLC-MMs in rat duodenum, jejunum, ileum and colon, and the content of cucurbitacin B was detected by HPLC method, and the effects of concentrations on intestinal absorption were evaluated as well. The results showed that the absorption of Cu B-SDC/PLC-MMs was linearity at different intestine segment and different concentrations (R2 > 0.9), which was consistent with zero order rate process. The Ka of different intestine segments showed a concentration-dependent increasing along with the raised concentration of Cu B-SDC/ PLC-MMs, indicating that it was likely to be a mechanism of passive absorption. The best absorption site of Cu B-SDC/PLC-MMs was ileum, and its absorptions in different intestinal segments were superior to cucurbitacin B suspension. SDC/PLC-MMs could significantly enhance the intestinal absorption of cucurbitacin B, and the study of intestinal absorption kinetics of Cu B-SDC/PLC-MMs had gave a support to its further reasonable solidfication.

To explore the feasibility of chemical and biological method in evaluation of the in vitro dissolution rate of Liuwei Wuling tablet (LWT), this experiment investigated the inhibitory effect of LWT dissolving solutions on LX-2 hepatic stellate cells in 0.1% SDS dissolution medium in different dissolving periods. From these results, the cumulative dissolution rate of LWT was obtained based on the cell inhibitory rate. The dissolution rates of deoxyschizandrin, phillyrin, and Specnuezhenide were determined by HPLC method. A novel approach of self-defined weighting coefficient had been created to establish the integrated dissolution rate model. Then f2 similar factor method was used to evaluate the relevance of these two methods. The results showed that f2 values for deoxyschizandrin, phillyrin, Specnuezhenide, and the integrated dissolution were 61, 43, 61 and 75 respectively, indicating that the dissolution of multi-component integration could fully reflect the biological potency of the whole recipe. The dissolution evaluation method for multicomponent integration based on biological activity is expected to be one of the effective means for in vitro dissolution test of LWT.

To study the influence of stir-baked with sand on active ingredients, diarrhea and hepatoprotection of Herpetospermum caudigerum, the contents of herperione and herpetin in H. caudigerum before and after stir-baking with sand were analyzed by HPLC. The effect of stir-baked with sand on diarrhea of H. caudigerum TL was evaluated using the mean stool rate (MSR) and mean diarrheal index ( MDI) and the influence of stir-baked with sand on hepatoprotective effect of H. caudigerum TL was examined using a mouse model of CCl4-induced liver injury based on the analysis of serum ALT and AST activities. The results of HPLC analysis showed the content of herperione in H. caudigerum after stir-baking with sand decreased by 40.9% (P < 0.01) and the content of herpetin had no change. Pharmacodynamic results showed that the MSR and MDI of high-dose and middle-dose group of H. caudigerum TL after stir-baking with sand were significantly lower than that of high-dose and middle-dose group of H. caudigerum TL without stir-baking with sand; The high-dose and middle-dose of H. caudigerum TL with/without stir-baking with sand significantly alleviated liver injury as indicated by the decreased levels of serum ALT and AST, but the ALT and AST levels of high-dose and middle-dose group of H. caudigerum TL after stir-baking with sand were higher than that of H. caudigerum TL without stir-baking with sand. The results revealed that the stir-baking with sand could effectively relieve diarrhea effect of H. caudigerum TL, while it also reduces the hepatoprotection of H. caudigerum TL.
