Aim To study inhibitory effect of 5-fluorouracil encapsulated by galactosylceramide liposomes (5-Fu-GCL)on 5-Fu-resistent HepG_2 cells and its mechanisms. Methods Inhibitory effect of 5-Fu-GCL on established model of 5-Fu-resistant HepG_2 cells was assessed with MTT assay in vitro. The concentration-time course of 5-Fu-GCL in intracellular fluid was detected with high performance liquid chromatography (HPLC). Thymidylic acid synthase (TS) expression was observed with immunohistochemical method,and NO content was determined with chemical method. Results Obvious inhibitory effects of 5-Fu-GCL (75,150,300,600,1200?mol?L-1) on 5-Fu-resistant HepG_2 cells were observed with IC_ 50 of 158.6 ?mol?L-1,far lower than that of free 5-Fu (400.9 ?mol?L-1). 5-Fu-GCL (300 ?mol?L-1) inhibited 5-Fu-resistant HepG_2 cells in a time-dependent manner,and the inhibitory effect of 5-Fu-GCL was stronger than that of free 5-Fu during 12～48 h. Compared with free 5-Fu,5-Fu-GCL (300 ?mol?L-1) increased the content of intracellular fluid in 5-Fu-resistant HepG_2 cells. 5-Fu-GCL(62.5,300,1200 ?mol?L-1) not only inhibited the expression of TS,but also increased the production of NO in 5-Fu-resistant HepG_2 cells,and these effects of 5-Fu-GCL(300,1200 ?mol?L-1) were stronger than those of free 5-Fu. Conclusion 5-Fu-GCL has inhibitory effect on 5-Fu-resistant HepG_2 cells. The effect may be related to the increased concentration of 5-Fu-GCL in intracellular fluid,inhibited expression of TS and increased production of NO.

Objective To examine mycological profile of eryptococcal meningitis in patients with non-acquired immune deficiency syndrome (AIDS) during treatment and follow-up so that to support clinical therapy. Methods Data of 28 cuhure-confirmed cryptoeoccal meningitis patients with non-AIDS were retrospectively analyzed. Fungat smear, count, culture and latex agglutination test of cerebrospinal fluid (CSF) were done during treatment and follow-up. Initial treatment included intravenous amphotericin B plus oral flucytosine or f;uconazole for at least 6 weeks, and consolidation treatment included oral fluconazole and (or) itraeonazole for at least 2 months. All 28 patients were cured. The data were analyzed by rank-sum test. Results The positive rate of CSF fungal smear was 92.9% before treatment and gradually decreased, and the fungal count was significantly reduced over time after treatment. While fungal smears of some patients were still positive after initial treatment. Fungal growth time in culture was gradually extended, and fungal culture turned to be negative in all patients after 2 weeks of treatment. The positive rate of latex agglutination test of CSF was 100%. Cryptococcal antigen titer decreased steadily after treatment, which was not correlated with the decrease of fungal count. Conclusion Mycological tests of patients with eryptococcal meningitis should be interpreted comprehensively during treatment, and result of each test should be specifically analyzed.

A novel drug delivery system combining oral fast dissolving film with sodium deoxycholate/phospholipid mixed micelles was prepared to increase the absorption of cucurbitacin B that is a poor aqueous solubility substance. Encapsulation efficiency, particle size, zeta potential, polydispersity coefficient, investigated the morphology, disintegration time of oral fast dissolving film and the pharmacodynamic properties of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles before and after solidified in mice were evaluated and compared. The oral fast dissolving film prepared in this study showed a homogeneous pale yellow and could completely disintegrated in the 30 s. It could meet the requirements of rapidly disintegrating fully. The encapsulation efficiency, particle size, zeta potential, polydispersity coefficient of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles loaded in oral fast dissolving film were (43.36 +/- 2.12)%, (108.82 +/- 5.2) nm, (-34.18 +/- 1.07) mV, 0.088 +/- 0.012, respectively. The encapsulation efficiency, particle size, zeta potential, polydispersity coefficient of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles in solution were (41.26 +/- 2.22)%, (181.82 +/- 4.48) nm, (-30.67 +/- 0.81) mV, 0.092 +/- 0.012, respectively. The difference of pharmacodynamics among film of cucurbitacin B-loaded micelles, cucurbitacin B-loaded micelles and free cucurbitacin B in vivo was compared. Solubility of cucurbitacin B loaded in sodium deoxycholate/phospholipid-mixed micelles has also been greatly improved. The tumor inhibition rate of cucurbitacin B loaded in sodium deoxycholate/phospholipid-mixed micelles was significantly improved and did not change significantly before and after solidified. These showed that the sodium deoxycholate/phospholipid-mixed micelles could enhance the antitumor activities of cucurbitacin B and the stability of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles was improved significantly after solidified by oral fast dissolving film technology without pharmacodynamic properties changed significantly.

Objective To study the effects of xanthoxylin on platelet aggregation and freeCa2+ level induced by CaCl2 and A23187. Methods Platelet aggregation and free Ca2+ level in the platelet cytosol were measured by turbidimetry and fluorimetry of Fura-2/AM. Results Xanthoxylin at the concentration of 0.037, 0.185, 0.924, 9.240, 92.40 μmol/L significantly inhibited CaCl2 and A23187-induced platelet aggregation, with the inhibition rates ranging from 9.0% to 67.1% for CaCl2 and from 18.1% to 72.5% for A23187. A23187-induced free-Ca2+ level in the platelet cytosol was also significantly reduced (from 12.8% to 63.4%). Conclusion The inhibition rate of platelet aggregation was positively correlated with the reduction rate of cytosolic free-Ca2+ level by xanthoxylin.

OBJECTIVETo investigate results of total knee arthroplasty using the long-stem tibial component combined with metallic wedge of knee prosthesis for the treatment of proximal defects.

METHODSFrom January 2011 to May 2013, 10 patients (11 knees) were treated with total knee arthroplasties using the long-stem tibial component with metallic tibial wedge of knee prosthesis. All the patients were female and the average age was 67 years old (ranged, 60 to 77 years old). All the patients were osteoarthritis. All the patients were classified as T2A style. The patients were evaluated according to knee score system (KSS).

RESULTSAll the patients were followed up for 12 months on average (ranged 3 to 29 months). The clinical outcome was assessed using KSS score, including knee pain score, knee stability score, knee range of motion score and knee walking score, knee stairs score. There were significantly differences at 6 weeks, 3 months, 6 months and 12 months between pre-and postoperative KSS score.

CONCLUSIONThe mechanical stability of tibial fixation in primary TKA is significantly increased by using the long-stem tibial component with metallic wedge of knee prosthesis, even in the presence of poor proximal bone.

This study was aimed to explore the effect of bone marrow-derived mesenchymal stem cells (MSC) on proliferation and activity of natural killer (NK) and NK-T cells. MSC was co-cultured with peripheral mononuclear cells from healthy donors in presence of IL-2, phytohemagglutinin (PHA) and mouse anti-human CD3 McAb (culture condition known to expand NK cells). The ratio of NK cells and NK-T cells was measured by flow cytometry and the effect of MSC on killing activity of NK cells against K562 cells was detected by MTT method after co-cultured with different densities of MSC. The results showed that MSC inhibited the production of NK cells in a dose-dependent manner generally. At the densities of 0, 1 × 10(5) and 5 × 10(5)/ml, the ratios of NK cells in the co-culture conditions were (16.9 ± 4.6), (14.0 ± 8.6) and (6.4 ± 4.6), respectively (P < 0.05). However, MSC could promote the formation of NK cells at lower MSC density (1 × 10(4)/ml), the ratio of NK cells reached to (20.9 ± 7.1), which was higher than that of culture condition without MSC (P < 0.05). The different densities of MSC in the co-culture conditions had no much influence on the ratio of NK-T cells (P > 0.05). MTT assay showed that the killing activity of suspended cells in co-culture system against K562 cells was parallel with the ratio of NK cells. Different densities of MSC regulated bidirectionally killing activity of NK to K562 cells by regulating bidirectionally ratio of NK cells. It is concluded that the MSC can promote the formation of NK cells and enhance its activity against tumor cells in the lower doses, while suppress the formation of NK cells and attenuate its tumor-killing effect in higher dose condition.
