5-Fluorouracil(5-FU)has been widely used to treat gastrointestinal,head,neck,chest and ovarian malignant tu-mors since 1957. As an analogue of pyrimidine,5-FU plays anti-cancer roles by inhibiting thymioylate synthase and integrating its me-tabolites into DNA and RNA. Although 5-FU is one of the first-line therapeutic compounds for gastrointestinal malignant tumor as a sin-gle drug or in combination with other drugs,its effectiveness is hindered by its low efficiency,which may be due to chemotherapy re-sistance. 5-FU chemotherapy resistance may stem from enzyme abnormality,genetic abnormality and tumor microenvironment. In this paper,we make a review about 5-FU actions and the mechanisms underlying chemotherapy resistance.

OBJECTIVE:To investigate the effect of insulin use intervention and self management of blood glucose in the treat-ment of cystic fibrosis related diabetes. METHODS:In prospective cohort study,during Apr. 2007-Apr. 2013,1 295 CFRD inpa-tients selected from 14 hospitals of Shanghai were randomly divided into trial group (743 cases) and control group (552 cases). Control group maintained the dose of insulin,and trial group adjusted the dose of insulin every week and received patient education about self management of blood glucose. Blood glucose,blood lipid,quality of life,the ability of self management and other in-dex were detected,recorded and compared between 2 groups 1 year after intervention. RESULTS:1 year after intervention,fasting blood glucose,postprandial 2 h blood glucose and HbA1c of trial group were significantly lower than those of control gorup,with statistical significance(P<0.05). The time of blood glucose reaching the standard,the dose of insulin,the number of hyperglycemia and hypoglycemia in trial group were all significantly shorter or lower than control group,with statistical significance (P<0.05). There was statistically significant difference in the rate of standard blood glucose between trial group [93.5%(695/743)] and control group [59.6%(329/552)]. TG of trial group decreased while HDL increased,there was statistically significant difference between 2 groups (P<0.05). There was statistically significant difference in the quality of life score between trial group (196.24 ± 15.80) and control group(180.33±16.29)(P<0.05). The ability of self management in trial group was significantly higher than control group, with statistical significance(P<0.05). CONCLUSIONS:Insulin use intervention and self management of blood glucose can control the level of blood glucose in CFRD patients,and improve the quality of life,medication compliance and therapeutic effect.

BACKGROUND:Bionic structure is one of the most important goals of scaffold design in tissue engineering. However, the majority of the bionic scaffolds do not have the capacity of sustained release of growth factors.
OBJECTIVE:To fabricate a novel biomimetic nanofibrous heparin/gelatin scaffold and investigate the characterization of the scaffolds including the microstructure, the mechanical strength andin vitro recombinant human bone morphogenetic protein-2 (rhBMP-2) release.
METHODS:Heparin-conjugated gelatin was prepared by chemical crosslinking and mixed with gelatin at different ratios. Nanofibrous composite scaffolds with different ratios of heparin-conjugated gelatin (0, 20% and 40%) were fabricated by using a thermaly induced phase separation combined with particle leaching technique. The amount of conjugated heparin in the scaffolds, scaffold microstructures and mechanical strength were detected and observed. The release kinetics of rhBMP-2 from the scaffolds with different concentrations of heparin conjugated gelatin was detected using ELISA method.
RESULTS AND CONCLUSION:The composite scaffolds possessed abundant porosities, good mechanical properties, and biomimetic nano-structures. The macroporous size was 250-420 μm. When the ratio of heparin-conjugated gelatin was 0, 20% and 40%, the content of heparin in the scaffolds was 0, (12.82±2.49) and (25.08±3.69) mg/g, respectively, with significant differences; the elastic modulus of the composite scaffolds was (299±38), (286±40) and (236±33) kPa, respectively, with insignificant differences (P > 0.05). With the increase in the content of heparin-conjugated gelatin, the rhBMP-2 adsorption capacity of the nanofibrous heparin/gelatin scaffold is improved, thereby significantly reducing the burst release of rhBMP-2 and prolonging the releasing time.

Objective To investigate the protective effects of ursolic acid (UA) on global cerebral ischemic-reperfusion injury in rats.MethodsThe experimental rats were divided into the sham operation group, the model group, the UA low, medium and high dose groups, 20 in each group. Except the rats in the sham operation group, the rats in other groups were dealed by four arteries occlusion to made global cerebral ischemia-reperfusion model. The rats in the UA low, medium, high dose groups were given UA as 40, 80, 120 mg/kg immediately after the occlusion line was inserted; the rats in the sham operation group and the model group were given equal-volume saline. And 6 hours later, the recovery time of righting reflex and electrical activity of brain were recorded, water content of the brain were evaluated, and the activity of LDH, MDA, SOD, CAT in brain tissue were determined; the inflammatory cytokines content of TNF-α, IL-1β, IL-6 were determined by ELISA. Results Compared with the model group, the recovery time of righting reflex (20.6 ± 7.2 min, 18.2 ± 6.9 min vs. 27.3 ± 8.8 min) and electrical activity of brain (16.2 ± 5.8 min, 14.9 ± 5.6 min vs.24.1 ± 7.2 min) of the UA medium and high dose groups were shortened (P<0.05 orP<0.01); the water content were significantly decreased (79.0% ± 0.7%, 78.6% ± 0.5%vs. 80.7% ± 0.9%;P<0.05 orP<0.01); the activity of SOD (158.5 ± 8.4 U/mg, 165.4 ± 9.0 U/mgvs. 143.0 ± 7.1 U/mg), CAT (3.3 ± 1.4 U/mg, 3.9 ± 1.5 U/mgvs. 2.4 ± 0.9 U/mg) in brain tissue of the UA medium and the high dose groups were significantly improved; the content of LDH (16.0 ± 2.6 mmol/g, 18.4 ± 2.8 mmol/gvs. 12.4 ± 1.9 mmol/g) were significantly increased; the content of MDA (18.6 ± 2.8μmol/g, 17.2 ± 2.4μmol/gvs. 24.9 ± 3.4μmol/g), TNF-α (45.8 ± 6.3 nmol/L, 40.1 ± 5.6 nmol/Lvs. 56.3 ± 7.2 nmol/L), IL-6 (187.2 ± 18.5 nmol/L, 136.8 ± 15.7 nmol/Lvs. 238.4 ± 22.9 nmol/L) were significantly decreased, and the content of IL-1β in UA 120 mg/kg treated group was significantly decreased (713.6 ± 56.3 nmol/L vs. 915.7 ± 70.5 nmol/L;P<0.05 orP<0.01).Conclusion UA can effectively promote righting reflex and EEG recovery, reduce brain water content, which perhaps related with its pharmacological effects of enhanceing the activity of antioxidant enzymes, lower oxidative stress, and inhibit inflammation.

Objective To evaluate the changes of hepatic blood perfusion of liver cirrhosis patients and the role of pericardial devascularization (PCDV)on them.Methods Hepatic artery and portal vein perfusions of 22 liver cirrhotic patients (LC) pre and post P CDV compared with control were evaluated with rheohepatogram(RHG) and ultrasonogram(USG).Results Compared with control,both hepatic and portal effective perfusion of LC were decreased on RHG, PCDV could increase portal perfusion of LC patients without significant effect on hepatic artery.USG showed that portal vein diameter and blood quantity of LC increased and PCDV didn't influence liver perfusion;No correlation between RHG and USG parameters were seen by STATA analysis. Conclusions RHG is an effective way to evaluate comprehensive blood perfusion of cirrhotic livers,the effect of operation on blood perfusion and prognosis.
