Objective To observe the recent effects and toxicity in advanced gastric carcinoma by two kinds of neoadjuvant chemotherapies ( PF and FOLFOX).Methods A total of 60 patients with advanced gastric cancer ( Ⅲ ～ Ⅳ ),they were randomly divided into 2 groups; PF group ( 30 cases) and FOLFOX group ( 30 cases).All patients were given 3 cycles of docetaxel or L-OHP chemotherapy preoperatively,to observe the recent effects and toxicity in advanced gastric carcinoma.Results The total effective rate in PF group was 77.67％,while it was 50.00％ in FOLFOX group,it had significant difference between in two groups ( x2 =4.59,P ＜ 0.05 ).There is no difference in the incidence of neutropenia,transaminase elevation,nausea and diarrhea two groups.The incidence of hair loss in PF group is higher than in FOLFOX group,but there is no difference between two groups; The incidence of peripheral nerve paresthesia in FOLFOX group is higher than that in PF group( x2 =5.08,P ＜0.05).Conclusion PF as neoadjuvant chemotherapy is a very effective and well-tolerated regimen in patients with advanced gastric cancer.

Objective To investigate the possible influence of immunosuppressive therapy,including sirolimus (SRL) and calcineurin inhibitors (CNI, tacrolimus), on level of Treg in the liver allo-graft recipients, Methods Forty-seven liver transplant recipients with stable liver function were assessed for at least 2 years, and divided into two groups: one composed of 15 patients receiving SRL,and another, of those receiving CNI (32 patients with tacrolimus). Thirty-eight age-matched healthy subjects (HS) were used as normal controls. We examined the expression of CD4, CD25, and Foxp3 in peripheral blood monouclear cells. Treg of every group was analyzed using Cell Quest software.Results SRL significantly increased the prevalence of CD4+ CD25high T cells, compared with HS and CNI group. The prevalence of CD4+ CD25high T cells of CNIs group was significantly lower than that of HS. The percentage of CD4+ CD25high T cells in the total CD4+ T cells was 1.88 % (1.56 %-2. 60 %), 1. 15 % (0. 57 %-l. 48 %) and 0. 84 % (0. 46 %-1. 45 %) in SRL, NS and CNI group,respectively (P<0. 01 or P<0. 05). Foxp3 was expressed in more than 95 % of CD4 + CD25high T cells and less than 20 % of CD4+ CD25low T cells, whereas not expressed in CD4+ CD25- T cells.Conclusion Different immunosuppressive therapy (SRL or CNI) might have different roles in tolerance induction in liver transplant recipients. Namely, SRL promoted the induction of allo-antigen tolerance, but CNI hampered the progression.

Using a UPLC-MS/MS (MRM) and cocktail probe substrates method, the metabolic fingerprint of the compatibility of Radix Aconite (RA) and Radix Paeoniae Alba (RPA) and its effect on CYP450 enzymes were investigated. These main CYP isoforms include CYP 1A2, CYP 2C, CYP 2E1, CYP 2D and CYP 3A. Compared with the inhibition effect of RA decoctions on CYP450 isoforms, their co-decoctions of RA and RPA with different proportions can decrease RA' inhibition on CYP3A, CYP2D, CYP2C and CYP1A2, but can not reduce RA' effect on CYP2E1. The metabolic fingerprints of RA decoction and co-decoctions with different proportions of RPA in CYP450 of rat liver were analyzed by UPLC-MS. Compared with the metabolic fingerprints of RA decoction, the intensity of diester-diterpenoid aconitum alkaloids decreased significantly, while the intensity of monoester-diterpenoid alkaloids significantly increased in the metabolic fingerprints of co-decoctions of RA and RPA. The results suggest that RA coadministration with RPA increased the degradation of toxic alkaloid and show the effect of toxicity reducing and efficacy enhancing.

OBJECTIVE: To explore whether pre-administration of Ganoderma lucidum spore (GASP) can reduce incidence of neural tube defects (NTDs) induced by all-trans retinoic acid (ATRA) in pregnant mice. METHODS: Twenty pregnant mice were randomly divided into four groups: normal control group, solvent-treated group, ATRA-induced group, and GASP-treated plus ATRA-induced group. GASP solution, which was prepared with solvent (sodium carboxymethyl cellulose), was fed to the pregnant mice in the GASP-treated plus ATRA-induced group twice a day from embryo (E) 0 d to E10.5 d. The same dose of solvent was given to the pregnant mice in the solvent-treated group. At E7.75 d, ATRA (50 mg/kg) was given to the pregnant mice in both ATRA-induced group and GASP-treated plus ATRA-induced group for single time. Embryos were sampled from pregnant mice at E10.5 d. Then the incidence rate of NTDs in mouse embryo was calculated and the crown-rump length of mouse embryo was measured. The positive rate of nestin expression and the distribution of cell cycle of embryonic neural tube neuroepithelial cells were detected by histochemical staining technique and flow cytometry respectively. Reverse transcription-polymerase chain reaction method was used to detect the gene expressions of cyclin-dependent protein kinase 2 (Cdk2) and Cdk4 mRNAs. RESULTS: The incidence rates of NTDs in mouse embryos in the ATRA-induced group and the GASP-treated plus ATRA-induced group were 79.41% and 21.67% respectively, while the crown-rump length of mouse embryos in these two groups were (3.62+/-1.27) mm and (5.84+/-0.92) mm respectively. The positive rate of nestin expression in embryonic neural tube neuroepithelial cells of mouse embryo at E10.5 d in the ATRA-induced group was 32.44%, while that in the GASP-treated plus ATRA-induced group was 77.65%. The cell cycle of embryonic neural tube neuroepithelial cells was obviously arrested at G(0)/G(1) phase in the ATRA-induced group as compared with that in the GASP-treated plus ATRA-induced group. The Cdk4 mRNA was transcripted at a high level in embryonic neural tube in the GASP-treated plus ATRA-induced group, but the Cdk2 mRNA was not detected in this group. CONCLUSION: Pre-administration of GASP can reduce the incidence of NTDs induced by ATRA in pregnant mice.
