BACKGROUND: Studies have showed that Chengzai pill is of distinct significance in the treatment of steroid-induced osteonecrosis of femoral head through increasing bone mineral density, bone weight, bone strength and rigidity, it also reverses the low levels of estrogen. OBJECTIVE: To explore the effect of Chengzai pill on the genes of cell adhesion molecules on bone cells of steroid-induced ostaonecrotic rats, and to understand the role to resume normal blood transport in femoral head of steroid-induced osteonecrosis. DESIGN, TIME AND SETTING: Grouping controlled observation was performed in the Pharmacological Laboratory of Wangjing Hospital of China Academy of Chinese Medical Sciences and laboratory of CapitalBio Corporation between March and August in 2006. MATERIALS: Six male SD rats of 6 months old and weighing (280:1:20) g were used in this study. Chengzai pill was consisted of 22 Chinese medicines, such as Chinese Angelica, Eucommia Bark, Milkvetch Root, Barbary Wolfberry Fruit, Degelatined Deer-hom, Desertliving Cistanche, Eupolyphaga seu Steleophaga, Leech, Danshen Root and Himalayan Teasel Root, which were offered by Beijing Boran Pharmaceutical Co., Ltd. METHODS: The lipopolysaccharide and methylprednisolone were applied to prepare a rat model of steroid-induced osteonecrosis of femoral head. Six rats were divided into model group and Chengzai pill group at random with 3 rats in each group. The rats in the Chengzai pill group were administrated with methylprednisolone for the first time and then 1.5 g/kg Chengzai pill solution, once a day, totally for 6 weeks. The total RNA was extracted from femoral head in all rata 6 weeks later and then gene expression profiling was analyzed. MAIN OUTCOME MEASURES: Gene action pathway of cell adhesion molecules in gene expression profile. RESULTS: Compared with model rats, there were totally 8 downregulated genes of cell adhesion molecules which changed by a minimum of 1.5 folds in cell adhesion molecules pathway of Chengzai pill group, three rats were present with 633 genes (506 down-regulated and 127 up-regulated), 883 genes (640 down-regulated and 243 up-regulated) and 593 genes (408 down-regulated and 185 up-regulated), respectively. MAS software classification analysis showed 79 action pathways were involved in 297 genes.CONCLUSION: Following Chengzai pill administration, those downregulated genes recover the cognitive functions of macrophage and target cell in rats, also renew the normal survival condition of epithelial cells including vascular endothelial cells. Cell adhesion molecules action pathway returns to normal levels. This is the key to resume normal blood transport in femoral head of steroid-induced osteonecrosis.

OBJECTIVETo explore the relationship between salivary proteome and dental caries and to promote the biomarker studies of dental caries susceptibility by comparing the salivary proteome of caries-active children and caries-free children with electrospray ionization ion-trap tandem mass spectrometry (ESI-MS/MS).

METHODSTen caries-active children and ten caries-free children were sampled. The salivary proteome of the two groups was studied, and the differential protein between the two groups was analyzed by ESI-MS/MS after sodium dodecyl sulfate polyacrylamide gel electrophoresis, filter-aided sample preparation, and liquid chromatography.

RESULTSThe concentration of salivary protein was higher in the caries-active group than in the caries-free group. The polypeptide counts of thecaries-active and caries-free groups were 602 and 481, which belonged to 286 and 227 proteins, respectively. The differential polypeptide count of the two groups was 361, and the differential protein count was 118. The detected proteins included matrix metalloproteinase-9 (MMP9), mucin-7 (MUC7), lactotransferrin (LTF), carbonic anhydrase 6 (CA6), azurocidin (AZU), and cold agglutinin.

CONCLUSIONThe total salivary protein was higher in the caries-active group than in the caries-free group. The preliminary detection of differential proteins (MMP9, MUC7, LTF, CA6, AZU, and cold agglutinin) may lay some foundation for biomarker research of dental caries susceptibility.

Cyclophosphamide (CPA) is the most common alkylating antineoplastic agent, as well as a strong immunosuppressant that is frequently applied to autoimmune diseases and organ transplantation. It is metabolized by cytochrome P450 oxidases (CYPs) to its active metabolite which played a critical role in therapy. CPA has serious and even fatal side effects, and its efficacy and adverse reactions are significantly varied among individuals. In this review, the association of the genetic polymorphisms in the metabolic enzymes and transporters involved in the disposition of CPA with the efficacy and adverse effects of CPA were summarized, thereby providing fundamental reference for further pharmacogenomic study of CPA.

Objective: To seek the optimal acupuncture time for primary dysmenorrhea and provide clinical basis for optimal acupuncture treatment protocol. Methods:A total of 90 eligible cases were randomly allocated into three groups, 30 cases in each group. Points Guanyuan (CV 4), bilateral Zusanli (ST 36) and Sanyinjiao (SP 6) were selected for patients in all three groups, with a different treatment duration: 15 min in group A, 30 min in group B and 45 min in group C. Then the clinical efficacy in each group was evaluated by pain symptom scoring. Results:As for the pain symptom scores, there were statistically significant intra-group differences between before and after treatment in three groups (allP<0.05); coupled with statistically significant inter-group differences between group B and the other two groups (bothP<0.05). As for clinical efficacy, there were statistical differences between group B and the other two groups (bothP<0.05), indicating that 30 min of acupuncture is the optimal duration in the treatment of dysmenorrhea. Conclusion:With the same needling manipulation, 30 min of acupuncture treatment achieves a better efficacy for primary dysmenorrhea.

This paper aims to develop a method for the determination of aloe-emodin, rhein, chrysophanol and physcion and study the pharmacokinetic properties of four anthraquinones in rat plasma after oral administration of gardenia and rhubarb decoction. The plasma concentrations at different time points of four anthraquinones were determined by HPLC-FLD method. Plasma samples were extracted with liquid-liquid extraction procedure. Plasma samples were separated on a C18 column (4.6 mm x 150 mm, 5 μm), using 0.2% acetic acid and methanol as mobile phase at a flow rate of 1.0 mL min(-1) with gradient elution. The excitation and emission wavelengths were set at 430, 525 nm, respectively. DAS 2.0 software was applied to calculate the pharmacokinetic parameters. The results showed four anthraquinones can be absorbed. The main parameters of aloe-emodin, rhein, chrysophanol and physcion were as follows: C(max) for aloe-emodin was (0.085 ± 0.058), (3.772 ± 1.152), (0.464 ± 0.267), (0.028 ± 0.008) mg x L(-1) respectively; t(max) for rhein was (1.042 ± 0.510), (0.805 ± 0.307), (1.167 ± 0.283), (0.616 ± 0.162) h respectively; t½ for chrysophanol was (3.557 ± 1.250), (6.879 ± 1.126), (5.196 ± 2.032), (4.337 ± 1.816) h; AUC(0-t) for physcion was (0.504 ± 0.130), (9.558 ± 1.106), (2.545 ± 1.554), (0.052 ± 0.018) mg x h x L(-1).
