Objective To study the effect of Xuebijing injection on the change of intestinal tract mucosa barriers and the expression of macrophage antihody in rats with sepsis. Method Totally 150 Wistar rats were ran-domly divided into three groups: sham group, sepsis group, and Xuebijing group. Sepsis models were estabhshed in rats by cecal ligation and puncture. The success standards of sepsis included fever, the increase of respiration rate,increased heart rate and change in leukocyte count. At 12 hours before operation, and after operation the rats in the Xuebijing group were injected with 4 mL/kg Xuebijing (once every 12 hours for 3 days), and the rats in the others two groups were injected with the same volume of saline, the image analytical system were used to detect the pathological change of intestinal tract mucosa harriers and the expression of macrophage antibody in three groups. All the data were analyzed by rank-sum test and variance analysis(F test). Results Almost all the mucous mem-brahe of small intestine in sham groups were normal. The mucous membrane lesions of small intestine developed in sepsis and Xuebijing groups after 12,24,48,72 hours, and the lesion was severer in sepsis group than that in the Xuebijing group (H=19.732, P<0.01). There were no significant differences on the expression of macrophage antibody in mucous membrane of small intestine between three groups at 3 hours. But at 12, 24, 48 and 72 hours, the expression of macmphage antibody of sepsis and Xnebijing groups increased with time (F=560.13, P< 0.05). Conclusions At the early period of sepsis, intestinal tract mucosa barriers develops varying degrees of damage, and Xnebijing can partly protect intestinal tract mucosa barriers.

Objective To evaluate the effect of curcumin on diabetic neuropathic pain (DNP) in rats. Methods Forty-eight male SD rats weighing 200-230 g were randomly divided into 6 groups ( n = 8 each) : group Ⅰ normal control (group C); group Ⅱ DNP (group D) ; group Ⅲ DNP+ DMSO (solvent of curcumin) (group DD) and group Ⅳ , Ⅴ , Ⅵ DNP + curcumin 50, 100 or 200 mg/kg ( group DC50, 100, 200 ). Diabetes was induced with intraperitoneal (IP) streptozocin 75 mg/kg in group Ⅱ -Ⅵ. Curcumin 50, 100 and 200 mg/kg were given IP once a day for 14 consecutive days starting from 14 d after streptozocin in group Ⅳ , Ⅴ and Ⅵ respectively. Venous blood samples were taken before and 72 h after IP streptosocin for determination of blood glucose level. Successful induction of diabetes was defined as blood glucose > 14.6 mmol/L. Mechanical paw withdrawal threshold to yon Frey stimuli (MWT) and paw withdrawal latency to thermal nociceptive stimulus (TWL) were measured 2 d before and 14 d after IP streptesocin and on the 1, 3, 7, 14 d of curcumin administration. Animals with pain threshold measured at 14 d after IP streptozocin decreasing by less than 15% of the baseline were excluded from the study. The animals were sacrificed after the last pain threshold measurement and the lumbar segment of the spinal cord and p65 was significantly higher in group D than in group C ( P < 0.05). Curcumin administration significantly reduced thermal and mechanical hyperalgesia induced by diabetes and down-regulated the expression of p-JNK and horn and DRG.

Objective To investigate the effect of ingredients-added Taohongsiwutang(a decoction of medicinal herbs, the decoction) on the secretion of endothelin-1 and basic fibroblast growth factor of kera-tinocytes. Methods Human keratinocytes were cultured in vitro. The viability and proliferation of kera-tinocytes treated with different concentrations of the decoction were assessed by MTT method. The concentrations of endothelin-1 and basic fibroblast growth factor in the supernatant were determined by ELISA. Results The proliferation of keratinocytes was promoted by 4.27, 5.49 and 6.1 mg/mL of the decoction, endothelin-1 secretion was stimulated by 1.83 and 5.49 mg/ml of the decoction in keratinocyte culture, but no effect on the secretion of basic fibroblast growth factor. Conclusions High concentrations of the decoction can promote the proliferation of keratinocytes. Different concentrations of the decoction can stimulate keratinocytes to secrete endothelin-1, which suggests that the decoction can stimulate keratinocytes to secrete endothelin-1 in vitro.

In this experiment, Hca-F or L615 elemene combo-TCV (H-TCV and L-TCV), H-TCV lysates, corynebacterium parvum (CP) were used to immunize 615 and Balb/c inbred mice, and their splenic DCs were prepared and pulsed in vitro with tumor cell lysates (H or L) and TCV lysates (TH or TL). The capacities of DCs to stimulate the proliferation of syngeneic nonadherent spleenic cells were tested with MTT assay. The results showed that the splenic DCs from normal mice in vitro pulsed with TH or TL could induced syngeneic noradherent splenic cells to proliferate (P<0.01), while the H or L pulsed DCs could not. The splenic DCs from H-TCV or L-TCV or TH immunized mice re-pulsed in vitro with TH or TL exhibited stronger stimulating effects than the DCs from normal mice pulsed in vitro for the firth time pulsed with TH or TL (P<0.01 or P<0.05); The capacities of DCs to induce proliferation of syngeneic nonadherent splenic cells could be further enhanced by CP immunization, especially when were pulsed with TH (P<0.01). Normal inbred 615 mice were transferred with DCs pulsed with lysates of elemene TCV (TDCs) or pulsed with lysates of Hca-F tumor cells (HDCs) on day 7 before challenged with lethal dose of live Hca-F cells, significant adoptive immunoprotective effects were seen, with 61.6% tumor inhibition rate and 25% survival in TDC adoptive transfer group. This study indicated that DCs might play a role in the mechanisms of active immunization and pulsing DCs with lysate of elemene combo TCV and isolating DCs from elemene combo TCV immunized mice were useful methods for DCs vaccine preparation.

Objective To study the association between functional genetic polymorphisms of IL-1B(T-31C,C-511T),IL-1RN and the susceptibility to gastric cancers. Methods A case-control study was conducted in 180 gastric cancer cases and 308 age-and sex-matched cancer-free controls.Genotypes were detected by PCR-restriction fragment length polymorphism(PCR-RFLP) assays,and association between genotypes,environmental factors and risk of gastric cancers were determined. Results IL-1B T-31C was in strong linkage disequilibrium with IL-1B C-511T(D'=0.862,R2= 0.721,P=0.000).Multivariate logistic regression analysis revealed that the variant genotypes of IL-1B T-31C and C-511T were not significantly associated with risks for gastric cancers(adjusted OR,0.95 and 95% CI,0.62-1.47 for IL-1B T-31C;and adjusted OR,0.85 and 95% CI,0.55-1.31 for IL-1B C-511T).The variant genotypes(1/2,2/2) in IL-1RN were associated with a non-significantly increased risks for gastric cancers(adjusted OR,1.32 and 95% CI,0.71-2.36) in all subjects and with a significantly increased risks for gastric cancers in subjects with H.pylori infection(adjusted OR,2.03 and 95%CI,1.02-4.80).Conclusion The functional genetic polymorphisms of IL-1RN may contribute to the risks of gastric cancers in high-risk population,particularly in those with H.pylori infection.

OBJECTIVETo study the relationship between compositions of hyperuricemia and metabolic syndrome among residents aged > or =20 years.
METHODSA stratified cluster sampling was conducted with 7887 dwellers recruited and examinaed. Blood samples were then collected for serum detection. Available data was analyzed using SPSS 13.0.
RESULTSThe incidence rates of obesity, hypertension and hyperglycemia for hyperuricemia were 53.4% with OR = 2.568 (95% CI: 2.103-3.137), 38.8% with OR= 2.157 (95% CI: 1.856-2.508) and 21.9% with OR = 1.850 (95% CI: 1.552-2.205) respectively. Along with the increase of uric acid, body mass index changed the most followed by triglyceridemia. The change of hyperglycemia for men and cholesterol for women were not prominent. Conclusion The relationship between compositions of hyperuricemia and metabolic syndrome was close, suggesting that hyperuricemia might serve as one of the compositions of metabolic syndrome and could contribute to the prevention and control of cardiovascular and cerebrovascular diseases.

To investigate the effect of flavonoids from Sophora flavescens in aging mice induced by D-galactose and its mechanism. Totally 60 mice were randomly divided into six groups: the control group, the model group, the piracetam group (positive control group) and flavonoids from S. flavescens low, medium and high doses groups. Except for the control group, all of the rest groups were subcutaneously injected with D-galactose (160 mg x kg(-1)) for successively 30 days to establish the sub-acute senescent model. Meanwhile, flavonoids from S. flavescens low, medium and high doses groups were respectively administered with 150, 300 and 600 mg xkg-('1)of flavonoids from S. flavescens for 30 days. The learning and memory abilities of mice were determined by avoiding darkness ex-eriment and jumping stair experiment. The contents of malondialdehyde (MDA) tumor necrosis factor-aα NF-aα the activities of superoxide dismutase (SOD) monoamine oxidase-B (MAO-B) Na'(+)K'(+)-ATPase and Ca2(+ )-ATPase in the brain of mice were deter-ined respectively after the behavioral experiments. The activity of lactic dehydrogenase ( DH) in blood serum was also determined and analyzed by microscope after HE staining to observe the changes in hippocampal organizational structure. Compared with the model group, flavonoids from S. favescens medium and high doses groups showed significantly increases in the latency of avoiding darkness and jumping stair experiments; flavonoids from S. fllvescens low, medium and high doses groups and the piracetam group showed de-reases in the numbers of errors in avoiding darkness experiment; the flavonoids from S. flavescens high dose group and the piracetam group showed reduction- n the number of errors in jumping stair experiment (P <0 . 5 or P <0 . 1). Flavonoids from S. flavescens me-ium and high doses groups and the piracetam group showed improvements in the activities of SOD, Na'(+)K'(+)ATPase in the brain of mice and declines in the contents of MDA and TNF-aα the activity of MAO-B in the brain of mice, the activity of LDH in blood serum (P <0 . 5 or P <0 . 1). Flavonoids from S. flavescens low, medium and high doses groups and the piracetam group also showed im-rovement in the activity of Ca2(+ )ATPase, with statistical difference from the model group (P <0 . 5 or P <0 . 1). The pathological result showed decreases in the number of cells of hippocampal dentate gyrus area, sparse cell arrangement, incomplete cellular mor-hology, scarce cytoplasm, blurred boundary between nucleus and cytoplasm, nuclei anachromasis, irregular pyknosis and unconspicu-us nucleoli in the model group. Compared with the model group, flavonoids from S. flavescens low, medium and high doses groups and the piracetam group showed improvements in hippocampal organization tissues. Flavonoids from S. favescens can improve the learning and memory ability of senescent mice induced by D-galactose. Its mechanism may be correlated with the enhancement of anti-oxidative actions by lowering TNF-aαcontent, which results in the stability of cell membrane and the reduction in MAO-B activity.
