To investigate the effects of carbamazepine (CBZ) on the plasma concentrations of valproic acid (VPA) and its toxic metabolite 2-propyl-4-pentenoic acid (4-ene VPA) in epileptic patients, the plasma concentrations of VPA and 4-ene VPA were determined, and the effect of CBZ on pharmacokinetics of VPA was evaluated. All patients had been divided into two groups (VPA group, n = 87; and VPA+CBZ group, n = 19). As compared to VPA group, the combination of CBZ significantly (P < 0.01) decreased the trough concentration of VPA [VPA group, (69.5 +/- 28.8) microg x mL(-1); VPA+CBZ group, (46.3 +/- 25.6) microg x mL(-1)] and does-adjusted VPA trough concentration [VPA group, (4.89 +/- 2.21) microg x mL(-1) x mg(-1) x kg(-1); VPA+CBZ group, (3.14 +/- 1.74) microg x mL(-1) x mg(-1) x kg(-1)]. However, the addition of CBZ did not influence the concentration of 4-ene VPA. The present study revealed that coadministration of CBZ can reduce VPA plasma concentration and may impact VPA clinical effect, therefore therapeutic drug mornitoring of VPA should be used when combined use of CBZ and VPA.

Objective To analyze clinical data of 6 cases of idiopathic hypertrophic pachymeningitis and review related literatures before, so as to offer a guidance for its clinical diagnosis and therapy. Methods We analyzed the clinical and imaging features and data of follow_up in the patients who were treated in our hospital 2005-2006. Results Idiopathic hypertrophic pachymeningitis was always accompanied by immune fimction abnormality to different degrees. The main clinical manifestation was headache which was found in every case. In these cases, headache was the onset and recur symptom. In addition to headache, various symptoms of nervous system dysfunction especially the cranial nerves could be found in some cases. In these cases, a localized or diffuse thickening of tentorium of cerebellum and/or falciform process of cerebrum was found in MRI, and intensification was presented in enhancement scanning. Corticosteroid was effective to all of the cases. Conclusions Idiopathic hypertrophic pachymeningitis may be an autoimmune disorder, of which the symptoms are various, and need to be discriminated from other diseases. MR/of cranium is important criteria for diagnosis.

OBJECTIVETo investigate the effects of the self-developed anti-heparanase polypeptide antibodies on growth and invasion of human hepatocellular carcinoma HCCLM6 cells.
METHODSUsing MTT, flow cytometry, plate clone formation, transwell invasion and heparan degrading enzyme assay, the growth and invasion changes of human hepatocellular carcinoma HCCLM6 cells by co-culture with each of three self-developed rabbit anti-heparanase polyclonal antibodies were detected.
RESULTSCompared with normal rabbit IgG, in the presence of each anti-heparanase polypeptide antibody, the growth, cell cycle and clone formation remained unchanged, and under the P1 or P2 anti-heparanase polypeptide antibody (with final concentration 100 microg/ml), the cell invasiveness was inhibited by 52.5% and 36.6%, respectively, and the heparanase activity was inhibited by 42.9% and 39.1%, respectively.
CONCLUSIONThe P1 and P2 anti-heparanase polypeptide antibodies can effectively inhibit the invasion ability and heparanase activity of liver cancer HCCLM6 cells. However, All the three antibodies have no effects on its growth, cell cycle and clone formation.

To investigate the influence of G-CSF mobilization on functions of donor T lymphocyte subpopulation and acute graft-versus-host disease, peripheral blood samples of 20 healthy donors were collected before and after G-CSF mobilization. The whole blood was diluted with IMDM in ratio of 1:1 and then incubated with PMA + ionomycin + monensin at 37 degrees C, 5% CO2 for 4 hours. After being mobilized and stained, the IL-4, IFN-gamma and IL-2 positive cells were counted with three-color flow cytometry. The results showed that before G-CSF mobilization, the percentages of donor's CD3(+)IFN-gamma(+), CD4(+)IFN-gamma(+), CD8(+)IFN-gamma(+) T cells were 3.2% (0% - 45.9%), 1.3% (0% - 23.8%) and 1.5% (0% - 22.2%) respectively. The percentage of above mentioned cells in donor increased to 19.2% (0% - 53.9%), 9.5% (0% - 49.5%), 7.5% (0% - 38.1%) respectively after G-CSF mobilization. The IL-2 positive CD3(+), CD4(+) and CD8(+) T cell percentage in pre-G-CSF mobilized donors was 1.5% (0% - 31%), 0.8% (0% - 30.0%) and 0% (0% - 5.3%) respectively and subsequently increased to 25.7% (0% - 51%), 19.8% (0% - 39.7%), 4.6% (0% - 20.9%) respectively after G-CSF mobilization. The IL-4 positive T subpopulation did not increased significantly after G-CSF mobilization. In the early stage after peripheral blood stem cell transplantation, donor's Tc1 percentage in aGVHD group was significantly higher than that in non-aGVHD group. The morbidity of severe aGVHD in high Tc2 percentage group was significantly lower than that in low Tc2 percentage group. It is concluded that the donor's type I T cells increase after G-CSF mobilization, the Tc1 percentage of G-CSF mobilized donor is correlated with the occurrence of aGVHD in the early stage after HSCT, the percentage of Tc2 in donor is negatively correlated with aGVHD morbidity in recipients.
