AIMTo investigate the impact of CYP2C9 * 3 on the pharmacokinetics of glibenclamide and lornoxicam.

METHODSCYP2C9 * 3 was measured in 83 non-related Chinese subjects by PCR-RFLP. The pharmacokinetics of lornoxicam and glibenclamide were investigated in 18 subjects (7 with CYP2C9 * 1/* 3 genotype and 11 with * 1/* 1 genotype). Glibenclamide and lornoxicam in plasma were determined by the sensitive liquid chromatography-tandem mass spectrometry, separately.

RESULTSAfter a single oral dose of 2.5 mg glibenclamide, C(max) was (70.0 +/- 11.5) microg x L(-1) in CYP2C9 * 1/ * 3 subjects and (51.9 +/- 12.3) microg x L(-1) in * 1/ *1 subjects. AUC(0-infinity) were (435 +/- 47) vs (287 +/- 95) microg x h x L(-1) (in * 1/ * 3 vs * 1/ *1 subjects), and CL/F were (96 +/- 9.3) vs (160 +/- 51) mL x min(-1), respectively. Statistic analysis results indicated that glibenclamide AUC(0-infinity) was significantly higher (1.5-fold) and subsequently CL/F was significantly lower (40%) in CYP2C9 * 1/ * 3 subjects than those in * 1/ * 1 subjects (P < 0.01). After a single oral dose of 8 mg lornoxicam, C(max) was (1.54 +/- 0.24) mg x L(-1) in CYP2C9 * 1/ * 3 subjects and (1.19 +/- 0.37) mg x L(-1) in * 1/ * 1 subjects. AUC(o-infinity were (14.9 +/- 2.2) vs (6.92 +/- 1.48) mg x h x L(-1) (in * 1/ *3 vs * 1/ * 1 subjects), and CL/F were (9.1 +/- 1.2) vs (20.1 +/- 4.6) mL x min(-1), respectively. Statistic analysis results indicated that lornoxicam AUC(0-infinity) was significantly higher (2. 2-fold) and subsequently CL/F was significantly lower (55% ) in CYP2C9 * 1/ * 3 subjects than those in * 1/ * 1 subjects (P < 0.001).

CONCLUSIONCYP2C9 * 3 greatly affects both the pharmacokinetic profiles of glibenclamide and lornoxicam. The elimination of these drugs significantly decreased in subjects with CYP2C9 * 1/ * 3 genotype, especially lornoxicam.

This study was designed to investigate the correlation between autophagy and polarization of macrophages in atherosclerosis (AS) plaque in arteriosclerosis obliterans amputees. Femoral artery specimens from arteriosclerosis obliterans amputees were performed hematoxylin and eosin (HE) staining, oil red O and immunofluorescence staining to observe the morphology of atherosclerotic plaque, phenotype of macrophages and autophagy in plaque; using real-time quantitative RT-PCR technology to detect the mRNA level of M1 and M2 type markers in arterial tissue; to analyze polarized signal pathway and autophagy protein levels in macrophages by Western blotting. Arterial specimens staining showed obvious lipid deposition and obvious infiltration of amount of foam cells and inflammatory cells. Macrophages were mainly expression M1 type in percentage in fibrous plaque. Although both M1 and M2 macrophages were upregulated in atheromatous plaque, the increase was dominant in M2 type in percentage. The level of autophagy was significantly higher in the atheromatous plaque than that of fibrous plaque. The expression of tumor necrosis factor- α (TNF-α), monocyte chemotactic protein-1 (MCP-1), inducible nitric oxide synthase (iNOS), interleukin-6 (IL-6) and interleukin-12 (IL-12) mRNA was significantly higher in fibrous plaque than that of atheromatous plaque (P < 0.01 or 0.05), and arginase-1 (Arg-1), transforming growth factor-β (TGF-β), CD163 and interleukin-10 (IL-10) mRNA was significantly lower than that in atheromatous plaque (P < 0.01). The levels of p-STAT1 and NF-κB were significantly increased in fibrous plaque (P < 0.01), while p-STAT6 expression was significantly increased in atheromatous plaque (P < 0.01). The level of LC3-II was significantly higher in atheromatous plaque than that in fibrous plaque (P < 0.01). Macrophages in early atherosclerotic plaque were induced to M1 type through p-STAT1/NF-κB pathway and expressed moderate levels of autophagy; while macrophages in advanced plaques were induced to polarization of M2 type through p-STAT6 pathway. M2 macrophages expressed a higher level of autophagy than M1 macrophages.

Mongolian folk medicine resource is the origin of Mongolian medicine development, even more important of which is the specialized Mongolian folk medicine resources with regional and high medicine quality, it processes distinctive national characteristics with irreplaceable important position in traditional Mongolian medicine. Nevertheless, due to the serious destroy of ecological environment and sharp increase of demands, etc. A lot of specialized Mongolian folk medicine resources were endangered, and there still existed some problems in the protection and exploitation and utilization. This paper intends to provide comprehensive insight into the species protection and exploitation and utilization states of specialized Mongolian folk medicine resources. The application and protection status and the existing problems were reviewed, and the development strategies of Mongolian folk medicine resource were analyzed.

OBJECTIVETo evaluate the influence of fast-track surgery in perioperative period on the clinical outcomes of patients with esophageal cancer.

METHODSClinical data of 117 patients with esophageal cancer between January 2011 and June 2011 were retrospectively analyzed. Sixty-three cases (study group) were treated with fast-track surgery and 54 cases(control group) were treated according to routine protocol in the perioperative period.

RESULTSThe operative time, time to drainage tube removal, and length of hospital stay were significantly shorter in the study group than those in the control group(all P<0.05). Compared with the control group, the medical cost was lower(P<0.05). The overall postoperative complication rate was 7.9% in the study group and 24.1% in the control group(P<0.05).

CONCLUSIONFast-track surgery in the perioperative period for patients with esophageal cancer can promote bowel function recovery and decrease morbidity.

To study the effects of recombinant human tumor necrosis factor-alpha (rhTNF-alpha) on HL-60 cells in vitro and in vivo, MTT and colony forming assay were used to examine the effects of rhTNF-alpha on proliferation of HL-60 cells; AO/EB (acridine orange-ethidium bromide) staining, Annexin-V flow cytometry analysis and TUNEL assay were used to detect apoptotic cells. The effect of rhTNF-alpha on xenograft growth of HL-60 cells was evaluated by tumor inhibition rate, histology, ultrastructure and TUNEL assay. The results showed that rhTNF-alpha inhibited the proliferation of HL-60 cells in a dose-dependent manner. Staining of cells with AO/EB revealed that rhTNF-alpha induced nuclear chromatin condensation and fragmentation. Positive Annexin V-FITC on cell membrane showed that rhTNF-alpha induced apoptosis of HL-60 cells in a dose-dependent manner. TUNEL assay showed that the apoptotic percentage of HL-60 cells reached 37.5% when incubated with 3200 U/ml rhTNF-alpha for 48 hours. In vivo rhTNF-alpha inhibited xenograft growth of HL-60 cells with the highest inhibition rate of 60.33%. Pathologically it was found that there were necrotic areas in the tumors of groups treated with rhTNF-alpha. There were more apoptotic cells in treatment groups than in that control group by transmission electron microscopy (TEM) and TUNEL assay. It is concluded that rhTNF-alpha is able to inhibit the proliferation of HL-60 cells and to induce apoptosis of HL-60 cells in vitro and in vivo.
