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.

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.

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 evaluate the correlation of interval from injury to surgery with outcome for central cervical spinal cord injury syndrome.Methods A retrospective analysis was done for 31 patients with central cervical spinal cord injury syndrome treated surgically between March 2007 and March 2011.According to the timing of surgical intervention,the patients were divided into early operative group (＜7 days from injury,n =14) and late operative group (≥7 days from injury,n =17).Japanese Orthopedic Association (JOA) score on admission,at postoperative half-year and at final follow-up were recorded and compared between the two groups.JOA recovery rate was determined and analyzed for correlation with operation time point.Results Mean follow-up was (16.1 ± 4.5) months (range,12-25 months).All patients had different degree of neurological recovery.JOA recovery rate in early operative group was apparently better than that in late operative group at final follow-up (P ＜ 0.01).JOA recovery rate at follow-up was negatively correlated with intervals between injury and surgery (r =-0.763,P ＜ 0.01).Conclusion For patients with central cervical spinal cord injury syndrome,time from injury to surgery is negatively correlated with outcome,indicating that early surgery may be associated with better outcomes.

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).
