Objective To investigate whether IL-17 could stimulate the vascular endothelial growth factor (VEGF) production on HaCaT cells alone. We also investigated whether shikonin could inhibited the proinflamation effects of interleukin-17(IL-17) acting on HaCaT cells. MethodsWe examined the expression of VEGF by double antibody sandwich enzyme-linked immunosorbent assay ( ELISA ) and realtime polymerase chain reaction(RT-PCR) in HaCaT cells and the cell supernatant. The viability of HaCaT cells in the drug group was detected by the Cell Counting Kit-8 (CCK-8). ResultsThe expression of VEGF in different time IL-17-stimulated groups on HaCaT cells and the cell supernatant were higher than the control group( P<0.001 ). The expression of VEGF in different drug treatment groups on HaCaT cells and the cell supematant were lower than the stimulated group by IL-17 ( P<0. 001 ). The cell viability of different drug treatment groups have no significant difference( P>0.05 ). ConclusionWe show that IL-17 specifically and time-dependently augmented and induced VEGF expression on HaCaT cells and the cell supernatantThen shikonin markedly inhibited the increase tengency of IL-17 effection on HaCaT cells and the cell supematant level.

Objective To study the effect of tranilast on cyclosporine A (CsA)-induced epithelial-to-mesenchymal transition in human renal tubular epithelial cells, and investigate the mechanism of its antifibrotic effect. Methods Cultured HK-2 cells were divided into four groups: (1)In the control group, cells were treated without any medicine; (2) The cell were treated with CsA (4. 2μmol/L) for 72 h; (3) The cells were treated with a combination of CsA (4. 2 μmol/L) and tranilast (100μmol/L); (4) The cells were treated with tranilast (100 μmol/L) alone for 72 h.Morphological changes of the cells were assessed by phase-contrast microscopy. The immunofluorescence and Western blotting were adopted to detect the expression of E-cadherin, α-SMA and OPN mRNA and proteins respectively. Results Tranilast could markedly ameliorate the morphological changes of HK-2 cells stimulated by CsA. The irmmunofluorescence staining revealed the expression of E-cadherin was markedly decreased in HK-2 cells stimulated with CsA for 72 as compared with the control group, while the expression of α-SMA and OPN was significantly higher in CsA group than the control group. The expression of E-cadherin in the CsA + Tranilast group was higher than the CsA group, while the expression of α-SMA and OPN in the CsA + Tranilast group was lower than the CsA group. Western blotting showed that protein expression level of E-cadherin in CsA group was dramatically lower than that in the control group (P<0. 05), while that of α-SMA and OPN in CsA group was significantly higher than in the control group (P<0.05). The protein expression level of E-cadherin in HK-2 cells in the CsA + Tranilast group was markedly higher than in the CsA group (P<0.05), and that of α-SMA and OPN in CsA + Tranilast group was significantly lower than in the CsA group (P<0. 05). Conclusion Tranilast can block the CsA-induced epithelialto-mesenchymal transition in HK-2 cells probably by suppressing the expression of OPN.

This study aims to investigate the function of two SNPs (rs8904C > T and rs696G >A) in 3' untranslated region (3'UTR) of NFKBIA gene by constructing luciferase reporter gene. A patient's genomic DNA with rs8904 CC and rs696 GA genotype was used as the PCR template. Full-length 3'UTR of NFKBIA gene was amplified by different primers. After sequencing validation, these fragments were inserted to the luciferase reporter vector, pGL3-promoter to construct recombinant plasmids containing four kinds of haplotypes, pGL3-rs8904C/rs696G, pGL3-rs8904C/rs696A, pGL3-rs8904T/rs696G and pGL3-rs8904T/rs696A. Then these plasmids were transfected into LS174T cells and the luciferase activity was detected. Compared with pGL3-vector transfected cells (negative control), the luciferase activity of the four kinds of recombinant plasmids was significantly decreased (P < 0.001). For rs696G > A, the luciferase activity of the recombinant plasmids containing A allele (pGL3-rs8904C/rs696A and pGL3-rs8904T/rs696A) was about 45.1% (P < 0.05) and 56.1% (P < 0.001) lower than those containing G allele (pGL3-rs8904C/rs696G and pGL3-rs8904T/rs696G), respectively. For rs8904C > T, there were no significant differences in the luciferase activity between the recombinant plasmids containing T allele and those with C allele. Together, the luciferase reporter gene vectors containing SNPs in NFKBIA gene 3'UTR were constructed successfully and rs696G > A could decrease the luciferase activity while rs8904C >T didn't have much effect on the luciferase activity.

OBJECTIVETo evaluate the impact of nutritional status on postoperative outcomes for patients with colorectal cancer.
METHODSData of 289 colorectal cancer patients from the Affiliated Hospital of Putian Medical College between January 2006 and December 2009 were collected prospectively. Nutritional status was evaluated according to Reilly Nutrition Risk Score(Reilly NRS) and Nutrition Risk Screening 2002(NRS-2002).
RESULTSThe postoperative mortality was 3.5%(10/289) and the complication rate was 29.4%(82/297). Patients were stratified into those at nutrition risk(n=89) and those not at risk(n=200) according to Reilly NRS and the two groups were similar in mortality rate(5.6% vs. 2.5%, P>0.05) and complication rate(36.1% vs. 26.5%, P>0.05). When stratified using NRS-2002, patients at nutritional risk(n=105) had a similar mortality rate (5.7% vs. 2.2%, P>0.05) but a higher complication rate(38.4% vs. 24.4%, P<0.05). NRS-2002 remained as an significant predictor of postoperative complications(P=0.007, OR=3.14, 95% CI:1.63-6.29) on multivariable logistic regression analysis.
CONCLUSIONAs a nutritional evaluation tool, NRS-2002 may predict postoperative complication for colorectal cancer.

Objective To observe apelin and its receptor (APJ) expressions in human osteoblasts and evaluate the effect of apelin on osteoblasts.Methods The expressions of apelin and APJ in human osteoblasts were tested by RT-PCR and Western blot.After human osteoblasts were treated with apelin,cell proliferation was measured by [~3H] thymidine incorporation and cell counting.Cell function was measured by alkaline phosphatase (ALP) activity,the secreted osteocalcin level and typeⅠcollagen production .The activation of signaling cascades was tested by Western blot.Small-interfering RNA (siRNA) to blockade APJ was applied to observe effects of apelin on cell proliferation and the activation of signaling cascades.Results Both apelin and APJ were expressed in human osteoblasts.Apelin increased the proliferation and did not show the influences on ALP activity, osteocalcin secretion and type I collagen production in human osteoblasts.Apelin induced activation of phosphatidylinositol-3 kinase (PI3K) downstream effector (Akt),but not mitogen-activated protein kinase (MAPK) such as c-jun N-terminal kinase (JNK),p38 and ERK1/2 in human osteoblasts.Suppression of APJ with siRNA or LY294002 (PI3K inhibitor) abolished the apelin-induced cell proliferation and the activation of Akt.Conclusion Human osteoblasts express apelin and APJ.Apelin stimulates the proliferation of human osteoblast via APJ/PI3K/Akt pathway,but has no effect on osteoblast differentiation.

Objective:This study aimed to investigate the effect of lipohypertrophy induced by insulin injection on blood glucose fluctuation in patients with type 1 diabetes mellitus.Methods:A total of 80 patients with type 1 diabetes mellitus were recruited between June 2021 and December 2021 from the First Affiliated Hospital of Nanjing Medical University. And these patients all received insulin injection more than six months. Lipohypertrophy was assessed by ultrasound scanning, and blood glucose fluctuation was evaluated using the flash glucose monitoring system(FGM). Univariate analysis and multivariate linear regression were used to analyze the relationship of lipohypertrophy and and core indicators of blood glucose fluctuation.Results:Compared with patients without lipohypertrophy, patients with lipohypertrophy had higher mean amplitude of glycemic excursions(MAGE), coefficient of variation(CV), mean of daily differences(MODD), standard deviation(SD) of blood glucose, time above range(TAR), and high blood glucose index(HBGI; all P<0.05), while time in range(TIR) of glucose markedly become lower( P<0.01). Moreover, multivariate linear regression analysis showed that lipohypertrophy detected by ultrasound was an independent influencing factor of TIR( β=-9.423, P=0.032), MAGE( β=1.114, P=0.039), CV( β=4.304, P=0.041), MODD( β=0.717, P=0.046) after adjusting for age at diagnosis, duration of insulin injection, fasting C-peptide, and daily dose of insulin per unit weight. Conclusion:Lipohypertrophy increases glycemic variability and imposes negative impact on glycemic control rate in patients type 1 diabetes mellitus.
