An HPLC method for the determination of geniposide concentration in mouse plasma was developed and the pharmacokinetics after intranasal administration of Xingnaojing microemulsion (XNJ-M) and mPEG2000-PLA modified Xingnaojing microemulsion (XNJ-MM) were investigated. Eighty mice were treated by XNJ-M and XNJ-MM nasally. The plasma samples were collected at different times and the drug in samples was detected by HPLC. The pharmacokinetic parameters were calculated by the software of Kinetica. The pharmacokinetic parameters of geniposide of XNJ-M were C(max) (4.36 +/- 2.69) mg x L(-1), t(max) 1 min, MRT (29.73 +/- 4.54) min, AUC (53.63 +/- 14.03) mg x L(-1) x min. The pharmacokinetic parameters of geniposide of XNJ-MM were C(max) (9.75 +/- 4.14) mg x L(-1), t(max) 1 min, MRT(22.34 +/- 2.90) min, AUC (131.87 +/- 40.13) mg x L(-1) x min. Geniposide can be absorbed into blood in a higher degree after intranasal administration with XNJ-MM compared to XNJ-M, which maybe caused by its less irritating and more absorption.

OBJECTIVETo explore the repair of Xiangsha Liujunzi Decoction (XSLJZD) on interstitial cells of Cajal (ICC) and gap junction (GJ) in the gastric muscular layer of rats of Pi-qi deficiency syn- drome (PQDS).
METHODSPQDS was established using purgative method with bitter and cold drugs in 30 healthy Wistar rats. After successful modeling they were randomly divided into the treatment group and the model group, 15 in each group. Another 15 healthy Wistar rats were recruited as the healthy control group. Rats in the treatment group were gastric administered with XSLJZD at 2 mL/100 g body weight, once daily for 14 successive days. Equal volume of normal saline was gastrically administered to those in the healthy control group and the model group. The gastric muscle tissues were taken out before modeling, before intervention, and after intervention, respectively. Ultrastructural changes of ICC and GJ were observed using transmission electron microscope (TEM). The number and distribution of Connexin43 (Cx43) were detected using immunohistochemistry.
RESULTSResults of TEM indicated that compared with the healthy control group, both ICC and GJ in the model group showed obvious injury. ICC and GJ were apparently repaired after intervention in the treatment group. Compared with the same group before modeling, the integrated optical density (IOD) of the Cx43 expression significantly decreased in the model group before and after intervention (P <0.05). Compared with before intervention, the IOD of the Cx43 expression significantly increased in the treatment group (P <0.05). Compared with the healthy control group, the IOD of the Cx43 expression significantly decreased in the model group before and after intervention (P <0.05). Compared with the model group, the IOD of the Cx43 expression significantly increased in the treatment group (P <0.05).
CONCLUSIONSUltrastructures of ICC and GJ in the gastric muscular layer of rats of PQDS were obviously damaged. XSLJZD could repair the structural damage of ICC and GJ in the gastric muscle tissues of rats of PQDS.

Objective To study the treatment effect on H22 tumor-bearing mice using ultrasound (US) combined with hematoporphyrin-loaded PLGA ultrasound contrast agents (HP-PLGA). Methods Hematoporphyrin-loaded PLGA ultrasound contrast agents were prepared using the technique of double emulsion, and the properties of the contrast agents were detected. Then 30 H22 tumor-bearing mice were averagely divided into 5 groups for different treatment. The growth curve of H22 tumor was depicted within 15 days after treatment. The inhibition rate of tumor quality on the 15th day and the index about apoptosis and proliferation on tumor of each group were measured, respectively. Results Self-made hematoporphyrin-loaded PLGA ultrasound contrast agents had mean size of 602.3 nm with encapsulation efficiency of 63.50% and drug loading of 2.15%. After treatment, tumors of the E group (US+HP-PLGA) grew most slowly compared with other groups. The inhibition rate of tumor quality and the apoptotic index in E group were significantly higher than those in other four groups (P<0.05), while the proliferation index in E group was significantly lower than that in other groups (P<0.05). Conclusion Ultrasound combined with hematoporphyrin-loaded PLGA ultrasound contrast agents could inhibit growth and promote the apoptosis of H22 tumor in mice, providing a novel strategy for sonodynamic therapy on the tumor.
