Objective To compare the difference in pharmacokinetics characteristics of vancomycin in cerebrospinal fluid between administration by continuous infusion and interim infusion.Methods Twenty postoperative patients in the Department of Neurosurgery of Beijing Tiantan Hospital, Capital Medical University admitted into intensive care unit (ICU) to receive vancomycin for prophylaxis of intracranial infection were enrolled, and they were randomly distributed to a continuous intravenous infusion group and a interim intravenous infusion group, each group 10 cases. In continuous intravenous infusion group, the patients received a loading dose of vancomycin (15 mg/kg) by continuous intravenous pump infusion for 1 - 2 hours followed by 30 mg/kg vancomycin in a constant pump infusion rate for 24 hours; while in interim intravenous infusion group, the patients received 15 mg/kg vancomycin administered by intravenous pump infusion for 1 - 2 hours, once every 12 hours. The concentration of vancomycin in the cerebrospinal fluid at different time points was measured by two-dimensional liquid chromatography (2D-LC) method, the parameters of pharmacokinetics were calculated in the two groups, and the adverse reaction was observed.Results The comparison between the ratio of areas under the concentration-time curves (AUC) and minimum inhibitory concentration (MIC) of the continuous and interim groups showed no significant difference (19.7±14.0 vs. 16.1±6.4,P > 0.05). However, in the continuous intravenous infusion group, the drug concentration reached the peak value (0.96± 0.77)μg/mL at 12 hours, and later revealed a plateau concentration 0.91-0.93μg/mL for 12 hours; while in the intravenous infusion interim group, the drug concentration reached the peak value (0.92±0.47)μg/mL at 16 hours, in the later 2 hours declined to (0.84±0.45)μg/mL, and afterwards still had a tendency of persistent declination. In all the patients, no any adverse reaction related to the drug occurred.Conclusion Continuous intravenous infusion and interim intravenous infusion of vancomycin for the postoperative neurosurgical patients without intracranial infection have the similar efficacy of medication, but the former can achieve the peak concentration faster and later the fluctuation of drug concentration in cerebrospinal fluid is smaller than those in the latter.

Aim To illustrate the role of Tanshinone IIA(TanIIA)extracted from dan-shen root in atherosclerosis and its different targets by investigating the effect on the expression of NF-?B、I?B-? and the mRNA of ICAM-1 and VCAM-1 in human umbilical vascular endothelial cell 304(ECV304).Mehods The TNF-?-induced cultured ECV-304 cell injury model was established to analyze the expression of NF-?B、I?B-? by cell ELISA method and the mRNA of ICAM-1 and VCAM-1 by RT-PCR method of the cells cultured with different denses of TanIIA.Results The results of ELISA method showed that the expression of the NF-?B was reduced significantly and the expression of the I?B-? was enhanced significantly in ECV304 which were cultured with higher denses of TanIIA.The results of RT-PCR method showed that the mRNA of ICAM-1 and VCAM-1 induced by TNF-? was significantly refrained.Conclusions TanIIA has a significant effect on inhibiting the mRNA of ICAM-1 and VCAM-1 induced by the NF-?B activation,so it can play an impotant role in resisting atherosclerosis.

30nm) accounted for 3.5% of these contacts. The mean maximum diameter of the vesicles was 49.4 nm, the volume density was 0.023 and profile density was 36. The distribution of the vesicles was as following: 29.1% opened onto or touched the abluminal membrane, 44,9% without visible connection to either surfaces, 26% opened onto or touched the luminal membrane. It was concluded that the mechanism of lymph formation in the stomach seems to be different from that of those organs such as heart, liver, kidney and thyroid. The present study suggested that the intercellular pathway may act as the primary route for lymph formation and macromolecule transportation, and the intracytoplasmic vesicular system may also play certain role in the transport of macromolecules.

Natural cyclopeptides are hot spots in chemical and pharmaceutical fields because of the wide spreading bio-resources, complex molecular structures and various bioactivities. Bio-producers of cyclopeptides distribute over almost every kingdom from bacteria to plants and animals. Many cyclopeptides contain non-coded amino acids and non-pepditic bonds. Most exciting characteristic of cyclopeptides is a range of interesting bioactivities such as antibiotics gramicidin-S (2), vancomycin (3) and daptomycin (4), immunosuppressive cyclosporin-A (1) and astin-C (8), and anti-tumor aplidine (5), RA-V (6) and RA-VII (7). Compounds 1-4 are being used in clinics; compounds 5-8 are in the stages of clinical trial or as a candidate for drug research. In this review, the progress in chemical and bioactive studies on these important natural bioactive cyclopeptides 1-8 are introduced, mainly including discovery, bioactivity, mechanism, QSAR and synthesis.
