FOXM1 is a member of the FOX family of transcription factors and has been confirmed to participate in cell prolifera-tion and cell cycle progress. FOXM1 has been reported to play an important role in more than 20 types of human neoplasms, and its up-regulation promotes tumor cell proliferation, invasion, metastasis, chemotherapy drug resistance, and resistance to apoptosis. In recent years, various studies have shown that FOXM1 also plays an important role in tumor metabolism. The metabolism of cancer cells deter-mines the growth and survival of cancer, and metabolic alteration is a key feature of tumor cells. The connection between metabolic ab-normalities and tumorigenesis has been reported. The O-linkedβ-N-acetylglucosamine transferase regulates the expression of FOXM1, which helps tumor cells survive without damage caused by oxidative stress. This review aims to summarize the known relationships of FOXM1 and tumor cell metabolism, as well as its role in the potential pathways of tumor metabolism.

The application of human embryonic stem cell(hES cell) contributes a lot to the disease treatment,and shows a great potentiality especially in organ transplantation and tissue engineering.Although hES cell therapy has not reached clinical application,some newly achieved results are encouraging.This review mainly presents results recently published in applying hES cell for disease treatment.

Objective To study the efficacy, safety and compliance of insulin human analog insulin aspart (NovoRapid) and insulin zinc protamine analog (Basulin) in the application on type 2 diabetes mellitus(T2DM)pafients during perioperative period. Methods Sixty T2DM patients were divided into 3 groups (n=20). Group A was treated with NovoRapid+Basulin, group B was treated with insulin human (Humulin R + Humulin N) and group C was treated with insulin pump (Humulin and NovoRapid). Blood glucose was detected in all of the patients before the meal, 2 hours after meal, before the sleep and during the operation. Results Blood glucose could all achieve the control level with the three methods of treatment. The rates of hypoglycemia in the three groups were 10%, 30% and 5% respectively, and the rates of patient satisfaction were 95%, 70% and 100% respectively. Conclusions Insulin human analog could control blood glucose effectively and safely, the compliance is also high. It is feasible of applying insulin human analog in the blood glucose control during perioperative period.

OBJECTIVE: To develop a sensitive and specific reverse-phase high-performance liquid chromatography (RP-HPLC) method to determine propofol in follicular fluid. METHODS: Thymol was added into follicular fluid samples as the internal standard, and the samples were then precipitated with methanol. After centrifugation at 20000 r·min-1 for 15 min, 20 μL of supernatant was directly injected into an Agilent Extend-C18 column (4.6 mm×250 mm, 5 μm). The mobile phase was composed of methanol-water (77:23). Analysis was run at a flow rate of 1.0 mL ·min-1. Fluorescence detection was applied with excitation and emission wavelengths of 276 and 310 nm, respectively. RESULTS: The calibration curves had good linearity in the range of 0.108-5.4 mg·L-1. The linear regression equation was A=0.2074ρ-0.0012(r=0.9993). The limits of detection and quantity proved to be 54 and 108 μg·L-1, respectively. The method recoveries for low, intermediate and high concentrations were 117.9%, 101.7% and 99.4%, respectively. The RSDs of inter-day assay were 4.10%, 1.28% and 0.20%(n=5), and intra-day assay were 4.34%, 2.33% and 0.61%(n=5), respectively. CONCLUSION: The method is accurate and convenient. It can be used to determine propofol for studying its clinical pharmacokinetics.

Objective To investigate the effects of simultaneous hepatic artery and portal revaseularization on the expression of TNF-α during bile duet ischemia-reperfusion injury in rats liver transplantation.Methods Male Spragne-Dawley rats were used to establish an autologous orthotopic liver transphmtation model.Model rats were random divided two groups,simultaneous revascularization group(sroup P)and portal vein revascularization group(group N).The animals were separately killed at the 2nd hour,6th hour and 24th hour after reperfusion.Plasma samples were collected for ALT,AST,GGT,AKP,TBiL and DBiL test.Bile duct tissues were collected to detect the histolosical changes,MPO activit,and the expression of TNF-α mRNA.Results The serum levels of GGT in group P was significantly lower than that in group N at the 6th hour and 24th hour after reperfusion(P＜0.05).And the serum levels of AKP,TBiL and DBiL and the morphological scores of bile duct in group P were significantly lower than that in group N at the 24th hour after reperfusion(P＜0.05).The activity of MPO in group N was significantly higher than that in group P at the 6th hour after reperfusion(P＜0.05).Compared with group N,the expression of TNF-αmBNA was reduced significantly in group P at the 2nd hour and 6th hour after reperfusion(P＜0.05).Conclusion Simultaneaus hepatic artery and portal revascularization can alleviate I/R induced bile duct injury of rat liver grafts,and the protective mechanism may be asseciated with inhibition the expression of TNF-α and decrease of neutrophil infiltration.

In continuation of our investigation, a new diterpene, rabdonervosin C (Ⅰ), was isolat-ed from the leaves and stems of Rabdosia nervosa (Hemsl.) C. Y. Wu et H. W. Li. Its structure wasidentified as lα, 15β, -dihydroxy-6β-ethoxy-6, 7-B-seco-ent-kaur-16-en-6, 20-epoxy-7, 20-δ-olide on thebasis of spectroscopic (MS, IR, 1HNMR, 13CNMR, DEPT and 2D-NMR) data and in comparison with theknown rabdonervosin A(Ⅲ) and B (Ⅱ).
