Objective To observe the effect of iodine excess(HI),polyinosinic-polycytidylic acid[Poly(I:C),Poly]and thyroglobulin(TG)on the thyroid of mice by the expression of Toll-like receptor 3(TLR3)to reveal the functional role of TLR3 in autoimmune thyroiditis.Methods Forty-two non-obese diabetic mice,body weight (20±3)g,were divided into six groups:control group,HI group,Poly group,TG group,HI+TG group,HI+Poly group. Fed with deionized water and injected intraperitoneally with physiological saline 0.1 ml each day for a week, the mice in control group were injected with physiological saline every other day at the same dose for 1 week before they were sacrificed; HI group drank 0.05% NaI water and were injected intraperitoneally with physiological saline same as control group; Poly group drank deionized water and were injected intraperitoneally with poly 0.1 ml (1 g/L)each day of the week, then the mice were injected with Poly every other day at the same dose for 1 week before they were sacrificed; TG group drank deionized water and were injected intraperitoneally with physiological saline same as control group, immunized with 0.1 mg TG by subcutaneously injecting and the immunization was enhanced after they were fed half dose for 4 and 8 weeks separately. In HI + Poly group, the treatment was the same as HI group and Poly group; HI + TG group: the treatment was the same as HI group and TG group. Eight weeks later, mice were sacrificed and thyroids were taken to make frozen sections, Hematoxylin-Eosin (HE) staining was employed to observe the morphological change of the thyroids. The expression of TLR3 of thyroids was observed under fluorescence microscope after Immumofluorescence using TLR3 antibody and TR3-positive cells were analyzed in the thyroid density. Results HE staining showed thyroids of Poly group had no inflammation under microscope.There were different degrees of inflammatory cell infiltration in HI group and TG group. The inflammatory cell infiltration and the damage of follicular thyroid of HI + TG group and HI + Poly group were serious, and the degrees of inflammation were higher over "++". Thyroid follicular epithelial cell with TLR3 expression could be seen in Poly group and HI group, meanwhile, there were TLR3 strong positive inflammatory cells in HI group under fluorescent microscope. Using stereological analysis of TLR3-positive cell density in the thyroid, the difference between groups was statistically significant(F=7.870, P<0.01 ). TLR3-positive cell density in the thyroid of HI + Poly group was higher[ (9.287 ± 0.522)mm2] than control group[ (0.062 ± 0.025)mm2, P < 0.01] significantly, meanwhile, the density in HI + Poly group was higher than HI group [ (2.574 ± 0.257 )mm2] and Poly group[ (1.361 ± 0.148 )mm2, all P < 0.01]. The density in HI + TG group[ (4.843±0.405)mm2] was higher than HI group and TG group[(1.601 ±0.268)mm2, all P < 0.01 )]. Conclusions Excessive iodine and thyroglobulin can induce thyroiditis, and stimulate the expression of TLR3 in the thyroid follicular epithelial, Poly aggravated thyroiditis induced by iodine excess in NOD mice; TLR3 positive inflammatory cells also appeared in inflammatory region, suggesting that TLR3 is involved in the pathogenesis of autoimmune thyroiditis

To prepare transdermal drug delivery system (TDDS) of felodipine and metoprolol and to study its pharmaceutical characteristics, pharmacokinetics and bioavailability in rabbits, an HPLC assay was established for the simultaneous determination of felodipine and metoprolol in the permeation receptor and patch. The permeation rate and permeation mechanism of felodipine-metoprolol-TDDS through rabbit skin in vitro was examined. The determination of drug content, the examination of content uniformity and stability of the TDDS were carried out. GC-ECD assays were established for the determination of felodipine and metoprolol in plasma separately and then employed to study the pharmacokinetics and bioavailability of felodipine and metoprolol after a single dose of oral or transdermal administration in rabbits. The results indicated that the permeation of flodipine and metoprolol from the patch through excised rabbit skin exhibited zero-order kinetic characteristics. The determination of drug content and the quality control of content uniformity of the patch accorded with Pharmacopoeia of the People's Republic of China of 2005 edition and the pharmaceutical characterization showed good stability. In contrast to oral delivery, relatively constant, sustained blood concentration with minimal fluctuation and prolonged peak time were observed over a long period after transdermal administration. The relative bioavailability of felodipine and metoprolol were 275.37% and 189.76% versus oral administration respectively. It was evident that the felodipine-metoprolol-TDDS exhibited good controlled release properties that satisfied the demands of original design that enhancing bioavailability and maintaining appropriate blood levels for a prolonged time without adverse effects associated with frequent oral administration.

OBJECTIVETo investigate the relationship between sensitivity to cisplatin (DDP) and the expression of HSP70 in cervical cancer cells in vitro.
METHODSCervical cancer Hela229 cells treated with different concentrations of DDP and the HSP70 inhibitor (PFT-µ) were examined for cell viability using MTT assay and colony forming ability. The cell apoptosis was analyzed by flow cytometry with propidium iodide staining and DAPI staining, and JC-1 staining was used to determine mitochondrial membrane potential. The expressions of HSP70, Bcl-2, Bax and caspase-3 were measured with Western blotting. A nude mouse model bearing Hela229 cell xenograft was used to evaluate the effect of DDP and PFT-µ on tumor growth.
RESULTSHela229 cells expressed a higher level of HSP70 than normal cervical cells. The combined use of PFT-µ significantly enhanced the inhibitory effect of DDP (P<0.01) and increased the cell apoptosis in Hela229 cells. JC-1 staining demonstrated that DDP combined with PFT-µ more obviously reduced mitochondrial membrane potential. DDP combined with PFT-µ more strongly lowered Bcl-2 expression and increased the expressions of casepase-3 and Bax than DDP alone. In the nude mouse model, PFT-µ significantly enhanced DDP sensitivity of Hela229 cell xenografts (P<0.01).
CONCLUSIONSInhibition of HSP70 expression can enhance the sensitivity of cervical cancer cell to DDP both in vivo and in vitro possibly by promoting cell apoptosis, suggesting the potential of HSP70 as a new target for gene therapy of cervical cancer.

Objective To investigate the influence of iodine excess on expression of TRAIl/TRAIL-sR1 in NOD and Balb/c mice and to study the effect of TRAIl/TRAIL-sR1 on the pathogenesis of experimental autoimmune thyroiditis(EAT). Methods Both Balb/c and NOD mice were divided randomly into control and iodine excess group by feeding with water containing no NaI or 0.05% Nal. The mice were sacrificed after 8 weeks. TRAIL and TRAIL-sR1 mRNA levels were detected by RT-PCR. The function, morphology and apoptosis of thyroids were also observed by ELISA and Tunnel stain. Results Treated by HI, enlarged follicles and flattened epithelium by accumulation of colloid were found in thyroids of both NOD and Balb/c mice. But significant lymphoid cell infiltration and local fibrosis were only found in thyroids of NOD HI group. The relative weight of thyroids of NOD mice in HI group[(104.8±14.5)mg/kg]was heavier than that of control group [(71.8±20.4)mg/kg]. The level of TT4 declined in HI group[(30.77±3.59)mmol/L]compared with control group[(36.43±2.66)mmol/L], meanwhile, the level of TSH was higher in HI group[(6.98±0.66)μg/L]than that in control group [(5.55±0.56)μg/L]. The difference being statistically significant(t=7.773,-9.526,-4.458, all P < 0.05). The relative weight of thyroids of Balb/c mice of HI group[(155.8±20.8)mg/kg]also heavier than that of control group [(105.1±22.0) mg/kg]. The level of TT4 droped in HI group [(19.75±3.32) mmoL/L]was higher than that in control group[(23.46±6.21)mmoL/L], the level of TSH in HI group[(4.14±1.71)μg/L]was higher than that in control group[(3.55±1.41)μg/L], the difference being statistically significant(t=7.554,-7.239,3.140, all P< 0.05). A great deal of apoptotie ceils observed in NOD (3.97±0.91) and Balb/c mice (1.05±0.45) by Tunnel stain were greater than control groups (0.21±0.15, 0.10±0.03), the difference being statistically significant in beth of the two species(t=-7.167,-17.772, both P < 0.05). The apoptosis index of thyroid follicular epithelium in NOD was obviously higher than Balb/c(t=-7.625, P<0.05). The level of TRAIL mRNA did not remarkably change in Balb/c between control group(0.000 59±0.000 39) and HI group(0.001 24±0.000 46, t=-1.940, P>0.05), but it increased apparently in NOD mice HI group(0.018 88±0.005 77) than that of control group(0.009 61± 0.00591, t=-2.71, P<0.05). The level of the expression of TRAIL-sR1 mRNA increased in HI groups of NOD (0.000 53±0.000 15) and Balb/c mice(0.000 42±0.000 09) than that in control groups of NOD(0.000 28± 0.000 05) and Balb/c mice (0.000 17±0.000 06) and the differences were statistically significant between the two species(t=3.050,3.990, all P<0.05). The differences of the expression of TRAIL and TRAIL-sR1 mRNA between the two species were significant(t=-3.37,-4.76, all P<0.05). Conclusions Iodine excess induces colloid goiter in beth species of mice and thyroiditis in NOD mice. The increase of TRAIL and TRAIL-sR1 influenced by iodine excess is one of the molecular bases of follicular epithelium apoptosis and inflammation in thyroids. Genetic factor is a key factor in the pathogenesis of thyroiditis.
