To investigate the principal metabolites of 1-(1-(6-methoxyl-2-naphthyl) ethyl)-2-(4-nitrobenzyl)-6,7-dimethoxyl-1,2,3,4-tetrahydroisoquinoline hydrobromide (code designation: P91024) in rats after ig administration by LC-MS/MS, the phase I metabolites were discovered by comparing the fullscan and SIM chromatograms of the test samples with the corresponding blanks. The structures of phase I metabolites were identified by ESI-MS spectra and the product spectra of the corresponding adduct ions. The phase II metabolites were identified in the test samples after the phase I metabolites were completely removed with solvent extraction and then treated with glucuronidase for enzymolysis of phase II glucuronide conjugates and the hydrolysates. Two phase I metabolites of P91024 were identified in rat feces, one phase I and five phase II in bile, one phase I and three phase II in urine, and four phase I and one phase II in plasma. Their structures were elucidated, separately. P91024 was extensively metabolized in rat. The metabolites can be easily screened and identified by LC-MS/MS method.

Objective To develop zoledronic acid (ZA)-loaded collagen membranes, and to study its effect on osteoclast and osteoblast so as to investigate whether ZA-loaded membranes can inhibit local bone resorption and promote bone formation. Methods ZA-loaded double-layer (Bio-Gide(R)) and singlelayer(BME-10X(R)) collagen membranes were prepared and divided into eight groups according to the concentrations of ZA in the membrane, namely Group BG0, BG1, BG2, BG3 and BM0, BM1, BM2, BM3 (BG refers to Bio-Gide(R), BM refers to BME-10X(R), 0, 1,2, 3 refer to the concentrations of ZA, 0, 1 ×10-4, 1 × 10-3, 1 × 10-2 mol/L respectively). Blank control group was set without using collagen membrane. The effects of ZA-loaded membranes on osteoclast and osteoblast were assessed using in vitro cell culture models. Results In vitro coculture of ZA-loaded membrane with osteoclast for seven days showed that the percentage of bone resorption area in BG1, BG2, BG3, BM1, BM2, BM3 were 18.80%,14.75%, 14.28%, 20.51%, 15.77%, 15.12% respectively, which were lower than that in BG0 (31.53%) and BM0(32.22%, P <0.05), and the higher ZA loading was, the stronger its inhibition to osteoclast was. In vitro coculture of ZA-loaded membrane with osteoblast for four days indicated that alkaline pbosphatase(ALP) activities in BG2 (154.67 U/g), BM2 (154.33 U/g), BG3 (155.33 U/g), BM3 (152.00 U/g) were higher than that in BG0(129.33 U/g) and BM0(127.67 U/g, P < 0.05). What's more, results from seven-day coculture showed that proliferation index in BG2(7.00) was higher than that in BG0(6.90). Conclusions ZA-loaded collagen membrane can not only inhibit osteoclastic bone resorption but also improve proliferation of osteoblast.

On the basis of the well-established principles and techniques about flow chamber, we have designed and made a kind of parallel plate system to apply steady fluid shear stress to osteoclast-like cells etc. in vitro. Biocompatible rubber and metal clamping apparatus made of aluminium alloy are used to seal the flow chamber without changing its even height designed beforehand. The influence of hydrostatic pressure on cells is minimized by adjusting the glass slide and the fluid surface in the upper reservoir to the same horizontal plane. This system can be used to investigate the responses of osteoclast-like cells etc. to fluid shear force in terms of morphology, physiology or biochemistry.

This study was aimed to discriminate the alleles in the HLA-C*07:01:01G and HLA-C*07:02:01G groups and analyze their associations with HLA-B locus. Samples previously typed as HLA-C*07:01:01G and HLA-C*07:02:01G were collected. The nucleotide sequences in exons 1 to 7 of the HLA-C locus were sequenced by polymerase chain reaction sequence-based typing (PCR-SBT) and HLA-B genotyping was also preformed by PCR-SBT in these samples. The results showed that 4 samples (30.8%) were confirmed as HLA-C*07:01:01 and 9 samples (69.2%) were HLA-C*07:06 among 13 samples previously typed as HLA-C*07:01:01G. Linkage disequilibrium (LD) analysis showed that HLA-C*07:06 allele was strongly related with HLA-B*44:03. All samples were typed as C*07:02:01 among 102 individuals previously typed as C*07:02:01G. LD analysis showed that C*07:02:01 was strongly related with HLA-B*51:01, B*46:01, B*39:01, B*40:01, B*38:02, B*15:02 alleles. It is concluded that HLA-C*07:01:01 and HLA-C*07:06 alleles are confirmed in the HLA-C*07:01:01G group and HLA-C*07:02:01 is a preferred allele in the HLA-C*07:02:01G.
