AIM:To research the effects of lithium chloride on transforming growth factor beta (TGF-β) and connective tissue growth factor (CTGF) in cultured human Tenon capsule fibroblasts (HTFs) and explore its mechanism.METHODS:HTFs were cultured and identified by vimentin staining with immunofluorescence and the morphological characteristics.The experimental group was processed 48h with LiCl in concentration of 80mmol/L, the control group without LiCl.The mRNA expression of TGF-β and CTGF in two groups were analyzed with real-time fluorescent quantitative polymerase chain reaction (real time-qPCR) and the protein expression was detected with Western blot.RESULTS:The cultured HTFs expressed TGF-β and CTGF.The mRNA expression of TGF-β and CTGF significantly decreased compared with the control group(t=20.042, 14.995, P<0.05).the protein expression of TGF-β and CTGF also decreased significantly compared with the control group(t=46.058、12.452, P<0.05)CONCLUSION:The cultured HTFs can express TGF-β and CTGF in mRNA and proteins' level.LiCl can reduce the expression of TGF-β and CTGF both in gene and proteins' level.LiCl has the potential to modulate wound healing for glaucoma filtration surgery.

Journal of Experimental Hematology 2009;17(4):1111-1117
Chemotherapy with traditional standard dose or autologous stem cell transplantation (ASCT) after chemotherapy with high dose have some remission effect for multiple myeloma, but relapse still exists. The maintenance treatment would prolonged the remission stage. These treatments included the use of alkylating agent, interferon, corticosteroids, thalidomide and so on. Every maintenance treatment has some advantages and some side effects. The truly effective maintenance treatment would not only minimize the harm of the disease, but also would prolong the overall survival, progression-free survival and the event-free survival. This article summarizes the current progress in the maintenance treatments for multiple myeloma.

Objective:To evaluate the immunogenicity of recombinant factor H binding protein(fHBP) by detecting serum antibody titer and serum bactericidal antibody test (SBA).Methods:fHBP sequence was selected and synthesized, connected to plasmid pET43.1a, transformed to Escherichia coli BL21(DE3), and expressed two recombinant fHBP proteins, included two subfamilies, fHBPA and fHBPB. After purification, the recombinant fHBP proteins were immunized to rabbits and mice. The immune antiserum titer and the bactericidal titer to epidemic strains of meningococcal bacteria group B were measured by ELISA and SBA respectively. Results:The antiserum titer of fHBP immunized rabbits was greater than 2.0×10 6, and that of immunized mice was not less than 1.0×10 6. fHBP immunized rabbit serum had bactericidal titer more than 1∶128 to 41 strains A subfamily and 20 strains B subfamily in the SBA against 69 endemic strains, and there was no cross-protection between the subfamily bacteria. The bactericidal titers of mouse serum immunized fHBPA to strains A subfamily such as Nm210902 Nm211009、Nm450522 were 1∶1 024, 1∶608、1∶861, to Nm510703、Nm311304、Nm431002 were 1∶234、1∶861、1∶430 respectively, and mouse serum immunized fHBP B to strains B subfamily Nm311302、Nm311304、Nm431002 were 1∶876、1∶274、1∶1858, all of three strains were positive in bactericidal titers. Conclusions:the titer of fHBP antiserum was higher than 1.0×10 6, the bactericidal titer was no less than 1∶128 to 61 epidemic strains, and it has a 94.2% protective effect on 69 meningococcal epidemic strains group B.

Objective To elucidate the effects of SP600125 at different concentrations on the proliferation and osteo-differentiation of human adipose-derived stem cells (hASCs).Methods The hASCs harvested were cocuhured with SP600125 at concentrations of 0 μmol/L,1 μmol/L,5 μmol/L and 10 μmol/L in growth medium (OM group) and in osteogenesis medium (OM group),respectively.The DNA quantitative assay was carried out to evaluate proliferation of the hASCs;flow cytometry was used to determine the effect of SP600125 on the cell cycles of hASCs;Alkaline phosphatase level (ALP) and calcium deposition tests were conducted to observe the effects of SP600125 at different concentrations on osteogenic differentiation of the hASCs.Results The proliferation of hASCs was inhibited by 42.1% when the cells were cocultured with SP600125 at the concentration of 10 μmol/L;the suppression decreased with decreased concentration of SP600125.The hASCs of phase G0/G1 in GM cocultured with SP600125 at the concentration of 10 μmol/L were more than those in GM cocultured with dimethylsulfoxide at the same concentration.ALP test revealed that after 10 days of culture in vitro the staining was more and more weakened and scattered and the ALP activity was more and more decreased with the increased concentration of SP600125.The extracellular calcium deposition of hASCs after 14 days of culture in vitro showed that the size and number of calcium nodules decreased with the increased concentration of SP600125.Conclusion SP600125 can suppress the proliferation and osteogenic differentiation of hASCs in vitro.

This study is to establish an HPLC-DAD-ELSD method for simultaneous determination of 5 flavones and saponins in Rhizoma Anemarrhenae including neo-mangiferin, mangiferin, timosaponin B II, timosaponin B III and timosaponin A III. Samples were analyzed on a Merck Purospher STAR column(4.6 mm x 250 mm, 5 μm). The mobile phase consisted of acetonitrile( A) and 0. 1% formic acid (B) with gradient elution at a flow rate of 1.0 mL · min(-1). The column temperature was set at 40 °C. The DAD detector wavelength was set at 254 nm. The ELSD conditions were as follows: the nebulizing gas flow rate was 2.0 L · min(-1) and temperature of drift tube was 105 °C. The volume was 10 μL. The five compounds were well separated with good linear correlations. The mean recoveries were between 102.0%-104.0%. This method was quick and reliable which provides a foundation for quality control of R. Anemarrhenae.

OBJECTIVE:
To investigate the diagnostic significance of basophil activation test (BAT) in anaphylaxis to non-ionic contrast media through testing the content of CD63, mast cell-carboxypeptidase A3 (MC-CPA3), and terminal complement complex SC5b-9 of the individuals by testing their levels in the normal immune group and the anaphylaxis groups to β-lactam drugs and non -ionic contrast media.
METHODS:
The CD63 expression of basophilic granulocyte in blood was detected by flow cytometry. The levels of MC-CPA3 in blood serum and SC5b-9 in blood plasma were detected by ELISA.
RESULTS:
The CD63 expression of basophilic granulocyte in blood, the levels of MC-CPA3 and SC5b-9 of anaphylaxis to non-ionic contrast media and β-lactam drugs were significantly higher than that in normal immune group (P < 0.05).
CONCLUSION
There is activation of basophilic granulocytes, mast cells and complement system in anaphylaxis to non-ionic contrast media. BAT can be used to diagnose the anaphylaxis to non-ionic contrast media.
