Objective To investigate the effect of mitogen-activated protein kinase(MAPK)pathway on the transcriptional expression of mdr1 gene induced by doxorubicin ( DOX)and study the transcription regulation of mdr1 gene.Methods K562 cells were treated with DOX(0.01 μg/ml)with the initial concentration of 0.01 μg/ml for 24 hours,then change the culture media without DOX.K562 cells were cultured until the its status wag recovered.Subsequently the cells were treated with DOX(0.02μg/ml)for 24 hours again.The concentration of DOX was increaged until 0.05 μg/ml by following the protocol above.K562 cells were collected at the concentration of 0.01 μg/ml,0.03μg/ml and 0.05μS/ml DOX.Expression of mdr1 gene were examined by reverse transcription-polymerase chain reaction(RT-PCR).Pglycoprotein(P-gP)wag detected by flow cytometry.Western blot wag performed to detect ERK and P-ERk.K562 cells were pretreated with MAPK inhibitor PD98059 for 1 hour.and then DOX was added.RT-PCR and FCM were used to detect the expression of mdr1 mRNA and P-gp.Results When K562 cells were exposured to DOX.the phosphorylation of ERK wag increaged.the mdr1 gene wag highly expressed as well as its corresponding protein P-gp.When the concentration of DOX was 0.05μg/ml,the expression of mdr1 gene and P-gp were increased over 5 fold.When K562 cells were pretreated with MAPK inhibitor PD98059,the expression of mdr1 gene induced by DOX(the concentration was 0.03 μg/ml and 0.05 μg/m1)was effectively inhibited by(74.1±0.11)%and(70.2±0.14)%respectively.Conclusions DOX could induce the expression of mdr1 gene in K562 cells accompanied by the activation of MAPK/ERK pathway.The block of activation of ERK could inhibit the induced expression of mdr1 gene.

Background and purpose: Increasing evidence has indicated that polymorphisms in the microRNA (miRNA, miR) binding site of target gene can alter the ability of miRNA and modulate the risk of cancer. We aimed to investigate the association between a miR-520a binding site single nucleotide polymorphism (SNP) rs141178472 in the PIK3CA 3’UTR and the risk of colorectal cancer in a Chinese Han population. Methods:The polymorphism rs141178472 was analyzed in a case-control study, including 386 colorectal cancer patients and 394 age-and sex-matched controls. The relationship between the polymorphism and the risk of colorectal cancer was examined by statistical methods. Results:Individuals carrying the rs141178472 CC genotype or C allele had an increased risk of developing colorectal cancer (CC vs TT, OR=1.716, 95%CI:1.084-2.716, P=0.022;C vs T, OR=1.258, 95%CI:1.021-1.551, P=0.033). Furthermore, the expression of PIK3CA was detected in the peripheral blood mononucleated cell of colorectal cancer patients, suggesting that mRNA levels of PIK3CA might be associated with SNP rs141178472. Conclusion:These ifndings provide evidence that a miR-520a binding site polymorphism rs141178472 in the PIK3CA 3’UTR may play crucial roles in the etiology of colorectal cancer.

Objective To observe the effects of individual prehabilitation on the functional outcome six weeks after total knee arthroplas-ty (TKA). Methods The patients undergoing TKA from March, 2013 to August, 2015 were randomly divided into prehabilitation group (n=30) and control group (n=29). The prehabilitation group received individual rehabilitation since enrolled in the study. The control group re-ceived no prehabilitation. All the patients received regular pre-surgical education, surgery and post-surgical rehabilitation. Both groups were evaluated with Numerical Rating Scale (NRS) of pain, active range of motion (AROM), Manual Muscle Test (MMT), fall index, TimedUp and Go(TUG), and Hospital for Special Surgery-Knee Scale (HSS-KS). Results The scores of NRS reduced six weeks after TKA (t>2.342, P<0.05) in both groups, and was lower in the prehabilitation group than in the control group before and six weeks after TKA (t>2.827, P<0.01). There was no significant difference in AROM of knee flexion when enrolling and before TKA in both groups (t<0.648, P>0.05), and it increased in the control group six weeks after TKA (t>3.555, P<0.01), and no increasement was found in the prehabilitation group (t<1.608, P>0.05);the AROM of knee extension increased before TKA in the control group (Z=-2.257, P=0.024), and no increasement was found in the prehabilitation group (Z=0, P=1.000), and it decreased six weeks after TKA in both groups (Z>2.247, P<0.05). The muscle strength of trunk extention and flexion enhanced before TKA in the prehabilitation group (t>2.387, P<0.05), and no change was found in the control group (t<0.940, P>0.05). The muscle strength of trunk extensor and the upside of rectus abdominis showed no statistical difference between two groups six weeks after TKA (t<1.656, P>0.05), the muscle strength of the downside of rectus abdominis and external oblique was more in the prehabilitation group than in the control group (t=2.585, P=0.013). There was no significant difference in the fall index be-fore TKA (t<0.350, P>0.05), and it was lower in the prehabilitation group than in the control group six weeks after TKA (t=-2.837, P=0.007). The time of TUG shortened before TKA in the prehabilitation group (t=3.554, P=0.002), and it prolonged in the control group (t=-4.507, P<0.001), there was no significant difference in it between two groups six weeks after TKA (t=-0.497, P=0.622). The score of HSS-KS increased before TKA (t=-2.621, P=0.015) in the prehabilitation group, and no increasement was found in the control group (t=2.073, P=0.053), and they were higher in the prehabilitation group than in the control group before and six weeks after TKA (t>2.092, P<0.05). Conclusion Individual prehabilitation could reduce pain, and improve the trunk muscles, the ability of walking and the function of the knee before and six weeks after TKA.
