OBJECTIVE:To study the improving effects of argatroban on the brain damage of model rats with cerebral hemor-rhage. METHODS:50 SD rats were randomly divided into normal control group(equivalent normal saline),model group(equiva-lent normal saline),argatroban high,medium and low dose groups (0.75,1.5,3 mg/kg). All groups,except for normal control group,were reproduced models with cerebral hemorrhage,and the rats in each group were treated by corresponding drugs after 30 min,ip,once a day. The rats were executed after continuous administration for 3 days. The data was detected,including the con-tents of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),activity of cysteine-containing aspartic protease 3(Caspase-3), expressions of Bcl-2,Bax,matrix metalloproteinase-2(MMP-2)and MMP-9,and the phosphorylations of nuclear factor κB(NF-κB) p65 and IκBα. RESULTS:Compared with the normal control group,the contents of TNF-α and IL-1β,the activity of Cas-pase-3,the expressions of MMP-2,MMP-9 and Bax proteins were increased;the expression of Bcl-2 was decreased;and phos-phorylations of NF- κB p65 and IκBα in model group were increased,with significant differences(P<0.01). Compared with the model group,the contents of TNF-α and IL-1β,the activity of Caspase-3,the expressions of MMP-2,MMP-9 and Bax were de-creased;the expression of Bcl-2 was increased;and phosphorylations of NF-κB p65 and IκBα in argatroban low,medium and high dose groups were decreased,with significant differences (P<0.01 or P<0.05). And it was positively correlated with the dose. CONCLUSIONS:Argatroban has dose-dependent inhibition effects on the inflammatory cytokine secretion and apoptosis of brain tissue of model rats with brain hemorrhage,and the mechanism may be related to NF-κB signaling pathway.

ObjectiveTo examine the effects of temsirolimus, an inhibitor of mammalian target of rapamycin, on bladder cancer cell lines T24 and BIU-87 in vitro and in vivo for purpose of evaluating the probability of mTOR targeted therapy for bladder cancer.MethodsAfter being treated by a different concentration of temsirolimus, T24 and BIU-87 cells were tested by MTT assay for cell proliferation activity.Cell cycle and apoptosis analysis were performed with flow cytometer. Wound scratch assay was used for cell migration activity and transwell motility assay. Western blot analysis was used to test the mTOR phosphorylation. Subcutaneous inoculation of 6-week-old nude mice was performed using 1 × 106 T24 cells in 50％ matrigel for both control (n = 10) and temsirolimus (n = 10) groups. The volume of tumors was examined and then the expression of Ki-67 was detected by immunohistochemistry.ResultsTemsirolimus significantly inhibited proliferation of T24 and BIU-87 cells in a dose- and time-dependent manner. After administration of temsirolimus on T24 and BIU-87 cell lines for 24 h, the rate of wound healing in 0 nmol/L groups were (88.9 ± 14. 1 ) ％ and ( 83.6 ± 16.3)％ , which were higher than in the 5 nmol/L groups, which were (42.7 ± 11.6) ％ and ( 36.9 ± 9.7 ) ％ ( P ＜ 0.05 ). In the transwell motility assay, the number of cells in the 0 nmol/L group was 26.5 ± 5.8 and 28.2 ± 4.6, which was higher than in the 5 nmol/L group ( 19.0 ±3. 8 and 21.3 ± 5.1, respectively) (P ＜ 0. 05). When temsirolimus was administered on T24 and BIU-87 cell lines for 48 h the percentages of cells delayed in phase G0/G1 in 5 nmol/L group were ( 77.46 ±6.11)％ and (73. 39 ± 4. 94)％ respectively, and higher than in the 0 nmol/L group, which were (65.99 ±5.01 )％ 、(60.15 ±3.98)％ (P ＜0.05). There was no statistically significant difference in the apoptosis rate between the two groups (P ＞ 0.05 ). In Western blot analysis, the ratios of p-mTOR/β-actin were 0.92 ±0.09 and 1.01 ± 0.08 in 0 nmol/L group, and higher than in the 5 nmol/L group (0.47 ±0.05、0.04 ±0. 01 ) (P ＜ 0.05 ). After administration of temsirolimus for 21 days, the tumor volume in nude mice in the control group were 351.1 ± 139.9 mm3 , which was larger than 351.1 ± 139.9 mm3 in the temsirolimus group ( P ＜ 0.05 ). The positive rate of Ki-67 expression was ( 67.3 ± 8.4 ) ％ in the control group, which was higher than in the temsirolimus group ( 35.5 ± 6.7 ) ％ ( P ＜ 0.05 ).ConclusionsThis study provides in vitro and in vivo evidence that temsirolimus may inhibit the viability of bladder cancer cells and temsirolimus could be exploited as a potential therapeutic strategy in bladder cancer.

Objective To investigate the effect of different concenrtrations of basic fibroblast growth factor (bFGF) on proliferation of human dental pulp cell in vitro,and to find out the most effective concentration of bFGF. Methods Dental pulp cells were isolated from dental pulp tissue explants.The pulp cells were divided into 5 groups randomly,bFGF was added into each group until the ultimately concentrations were 0.1,1.0,10.0 and 100.0 ?g?L-1respectively while the group without bFGF as control group.

Objective To evaluate the effects of metformin on thyrotropin(TSH)levels. Methods From the patients with type 2 diabetes mellitus or metabolic syndrome, 48 patients with primary hypothyroidism were enrolled and grouped. 17 patients were treated only with metformin(group A), 19 patients with metformin and stable L-T4substitution(group B), and the remaining 12 patients with antidiabetic drugs(other than metformin)and L-T4(group C). Meanwhile, 20 euthyroid patients with other thyroid abnormalities(group D)and 30 patients without thyroid diseases(group E)served as control. TSH, FT3, FT4, TT3, TT4, and blood glucose were determined regularly in all these subjects. Results After administration of metformin for 12 months, serum TSH were decreased in group A [(5.05±1.07 vs 2.61±0.91)mU/L, P＜0.01] and group B [(2.67±1.03 vs 1.35±0.74)mU/L, P＜0.01]. No difference was found in FT3and FT4in both groups. TSH levels were raised from(1.30±0.71)to(2.58±1.02)mU/L(P＜0.01)within 8～12 weeks in 13 out of 15 patients after metformin withdrawal. Serum TSH and thyroid hormones in the other 3 groups were not significantly changed. Conclusion Administration of metformin may lead to reduction of serum TSH level.
