Objective To investigate the mechanisms underlying the protection by punicalagin against ultraviolet B (UVB)-induced damage to keratinocytes.Methods Cultured human HaCaT keratinocytes were divided into several groups:blank control group receiving no treatment,punicalagin groups treated with various concentrations of punicalagin,UVB group irradiated with UVB at 30 mJ/cm2,combination groups pretreated with different concentrations of punicalagin followed by UVB radiation at 30 mJ/cm2.The concentrations of punicalagin were 5,10,20,40 and 80 μmol/L in the cell proliferation assay,10,20 and 40 μmol/L in the other assays.After additional culture for different durations,methyl thiazolyl tetrazolium (MTT) assay was performed to evaluate the proliferation of HaCaT cells,Hoechst and propidium iodide (PI) staining as well as flow cytometry to detect the apoptosis in cells,reverse transcription-PCR to quantify the mRNA expressions of matrix metalloproteinase-1 (MMP1) and tissue inhibitor of metalloproteinase-1 (TIMP1) in HaCaT cells,Western blot to determine the phosphorylation levels of the mitogen-activated protein kinase (MAPK) pathway-related proteins including P38,JNK and ERK.Statistical analysis was carried out by t test,one-way analysis of variance,and Dunnett's t-test.Results As the MTT assay showed,punicalagin at 10-40 μmol/L showed stronger pre-protective effects against UVB-induced damage to HaCaT cells compared with punicalagin at the other concentrations.The number of cells highly positive for both Hoechst and PI staining was larger in the UVB group than that in the blank control group,but smaller in the combination groups than in the UVB group.The percentage of apoptotic cells increased significantly in the UVB group compared with the blank control group (9.82％ ± 0.11％ vs.1.24％ ± 0.91％,P ＜ 0.01),but decreased significantly in the three combination groups (punicalagin (10,20 and 40 μmol/L) + UVB) compared with the UVB group (6.38％ ± 0.14％,5.24％ ± 0.17％ and 3.77％ ± 0.11％ vs.9.82％ ± 0.11％,all P＜ 0.01).Theexpression of MMP1 mRNA was significantly higher,but that of TIMP1 mRNA was significantly lower in the UVB group than in the blank control group (both P ＜ 0.01),whereas no statistically significant difference was observed in the expression of MMP1 or TIMP1 mRNA between the punicalagin groups and blank control group (all P ＞ 0.05).The pretreatment with punicalagin significantly reduced the expression level of MMP1 mRNA (P ＜ 0.01),but elevated that of TIMP1 mRNA (P ＜ 0.01) in the combination groups compared with the UVB group.As Western blot showed,the phosphorylation levels of P38,JNK and ERK were markedly increased in the UVB group (all P ＜0.01),but experienced no significant changes in the punicalagin groups (all P ＞ 0.05) compared with the blank control group,and decreased to different degrees in the combination groups compared with the UVB group (all P ＜0.01).Conclusion Punicalagin has a pre-protective effect on UVB-induced damage to HaCaT cells.

Objective To evaluate the effects of tacrolimus on the secretion of IL-6 and sIL-2R as well as the expression of IL-6 and sIL-2R mRNA by lymphocytes.Methods Jurkat human lymphoma cells were cultured and treated with tacrolimus of different concentrations.Enzyme linked immunosorbent assay was performed to determine the levels of IL-6 and sIL-2R in the supernatant of Jurkat cells at 48 hours after treatment with tacrolimus of 0,10,102,103 and 104 nmol/L,and real time reverse transcription PCR to measure the expression of IL-6 mRNA and sIL-2R mRNA of Jurkat cells at 48 hours after treatment with tacrolimus of 102 nmol/L.Results Tacrolimus of 102 - 104 nmol/L could suppress the secretion of IL-6 and sIL-2R from Jurkat cells (all P＜ 0.05),with a more marked suppressing effect achieved by the use of tacrolimus at 103 - 104 nmol/L.The expressions of IL-6 and sIL-2R mRNA from Jurkat cells were downregulated by tacrolimus of 102 nmol/L (both P ＜ 0.05).Conclusion Tacrolimus at certain concentrations could downregulate the secretion of IL-6 and sIL-2R as well as the expression of IL-6 and sIL-2R mRNA by lymphocytes.

Objective The regulation of ornithine decarboxylase (ODC) gene expression and enzyme activity by corticosterone, the main glucocorticoid in rat, during rat liver regeneration induced by partial hepatectomy (PH) was evaluated.Methods Bilateral adrenaleetomies (ADX) and sham-ADX were performed on ether-anesthetized rats 3 days before PH.Corticosterone in sesame oil was injected subcutaneously to adrenalectomied rats. ODC mRNA, ODC protein and enzyme activity were detected by RT-PCR, Western blotting and high performance liquid chromatography (HPLC), respectively. Results The ODC mRNA levels, protein accumulation and enzyme activity were lower in the intact liver compared to the regenerating liver.After PH, mRNA levels were remarkably enhanced in all groups (n=6 in each group) and peaked at 5 hours post-PH. Till 7 hours, the contents in all groups from high to low were ADX group,control group (Sham-ADX group), ADX treated with 10mg/kg and 40mg/kg body weight corticosterone group, respectively. ODC protein accumulation in ADX rats was higher than that in control rats (n=13, the same below), but it decreasod in corticosterone-treated (10mg/kg) rats until 24 hours post-PH, with a strong decline seen in 40mg/kg corticosterone-treated rats. ODC activity was rapidly promoted, and the highest levels were observed at 6 hours after PH in all groups (n=6 in each group). After corticosterone treatment, the activities declined significantly at 6 hours post-PH, with the lowest value found in the 40mg/kg group. Conclusion Corticosterone treatment results in dose-dependent decreases in ODC mRNA and enzyme protein both in the intact liver and the regenerating liver. The change in ODC activity is partially related to alterations of ODC mRNA and protein accumulation.

ObjectiveTo investigate the L-hydroxyproline (L-Hyp) changes in rats' skin after exposed to different doses of ultraviolet C irradiation (UVC) and the effect of UVC radiation on collagen synthesis.MethodsAfter the animal model was set up, each male Wistar rat was made three fresh skin wounds, and three skin wounds of rats were divided into the 15 MED UVC irradiation (15mJ/cm2),60 MED UVC irradiation (60mJ/cm2) and control (without UVC irradiation). Then the chemistry method was utilized to research changes of L-Hyp contents of the granulation.ResultsFrom the 21st to the 28th day after UVC irradiation, contents of L-Hyp in the 15 MED group were higher than that in controls (P<0.05). While at the 28th day, L-Hyp level in the 60 MED group increased greatly and was higher than that in other two groups (P<0.01).ConclusionUVC irradiation increases L-Hyp level in rat's wound skin, so it accelerates the collagen synthesis and is helpful to promote wound healing, and the effect of 60 MED dose is superior to that of 15 MED.
