Objective To investigate the effect of integrin-linked kinase (ILK) on inducing mesenchymal stem cells (MSCs) to neuron stem-like cell in vitro. Methods MSCs isolated from umbilical cord were transfected with plasmid DNA encoding green fluorescent protein (GFP) and GFP-fusion ILK, wild and mutant, respectively; and cultured in serum-free media with basic fibroblast growth factor, epidermal growth factor and B27. It was assessed with the proliferative activity and the efficiency of differentiation into neural stem-like cell. Results MSCs transfected with GFP-fusion wild ILK expressed ILK and kinase-dead mutant ILK stably. The activity of proliferation increased and more of them differentiated into neural stem-like cell, which express CD133 and Nestin validated by PCR and Western blotting, and more of wild than of mutant. Conclusion Integrin-linked kinase may play a positive role in MSC differentiation into neural stem-like cell, which may associate with the activity of kinase.

Objective To investigate the inhibitory effect of testosterone on oxidized low-density lipoproteins ( ox-LDL)-stimulated phenotypic transition and proliferation of vascular smooth muscle cells ( VSMCs) in vitro, and to explore its possible mechanisms. Methods Rat VSMCs cultured in vitro were divided into control group, ox-LDL group(50μg/mlox-LDL),fetalbovineserum(FBS)group(10% FBS),andtestosteronegroups(5×10-8 or5×10-7 mol/L testosterone plus 50μg/ml ox-LDL) . The effect of testosterone on ox-LDL-induced proliferation of VSMCs was explored by WST-1 assay. The cell cycle distribution was determined using flow cytometry. Western blotting was used todetecttheexpressionsofmitofusin2(Mfn2),phosphorylatedextracellularsignal-regulatedkinases1/2(p-ERK1/2) , proliferating cell nuclear antigen ( PCNA) ,α-smooth muscle actin (α-SMA) ,and osteopontin ( OPN) . Results Compared with control group, the proliferation of VSMCs was promoted by ox-LDL, the number of VSMCs decreased in G0/G1 phase and increased in S phase significantly, the expression levels of Mfn2 and α-SMA were significantly reduced, and the expression levels of p-ERK1/2, PCNA, and OPN were significantly raised in ox-LDL group. Compared with ox-LDL group, the proliferation of VSMCs was inhibited, the number of VSMCs increased in G0/G1 phase and decreased in S phase in two testosterone groups, along with the increased expressions of Mfn2 andα-SMA, and the descended expressions of p-ERK1/2, PCNA, and OPN. Conclusions Testosterone inhibits phenotypic transition and proliferation of VSMCs induced by ox-LDL in vitro, which may be related to the up-regulated expression of Mfn 2 and the suppression of ERK1/2 pathway.

Objective To estimate the influence of palmitic acid (PA) on the proliferation of and production of inflammatory mediators by a human keratinocyte line HaCaT.Methods Cultured HaCaT cells were treated with PA of eight concentrations (0-200 μmol/L) for 3-24 hours followed by the evaluation of cell proliferation by using the cell counting kit-8.According to the proliferation assay,four concentrations (75,100,125,150 μmol/L) of PA were selected and used to treat HaCaT cells for 24 hours,then,fluorescence-based immunohistochemical staining was performed to observe the nuclear translocation of nuclear factor (NF)-κB p65,enzyme linked immunosorbent assay (ELISA) to determine the level of interleukin (IL)-6 in the supernatant of culture medium,real-time PCR to detect the mRNA expressions of peroxisome proliferator-activated receptor oα (PPARα) and IL-6,and Western blot to quantify the protein expressions of PPARα as well as total and nuclear NF-κB p65.Those HaCaT cells receiving no treatment served as the control group.Statistical analysis was carried out by one-factor analysis of variance using the GraphPad Prism 5.0 software.Results The HaCaT cells treated with PA of 50-175 μ mol/L showed accelerated proliferation compared with the control HaCaT cells (all P ＜ 0.05).PA from 75 to 150 μmol/L enhanced the nuclear translocation of NF-κB p65,mRNA and protein expressions of PPARα,as well as the mRNA expression and supernatant level of IL-6 in a dose-dependent manner.The relative expression level of nuclear NF-κB p65 protein was 0.4536 ± 0.0173,0.5184 ± 0.0206,0.5333 ± 0.0231,0.6160 ± 0.0297,and the supernatant level of IL-6 was (31.5677 ± 0.2268),(32.3773 ± 0.4156),(32.9837 ± 0.0029) and (33.6890 ± 0.0936) ng/L,in HaCaT cells treated with PA of 75,100,125 and 150 μmol/L,respectively,compared to 0.3237 ± 0.0114 (all P ＜ 0.01) and (30.4577 ± 0.5131) ng/L (all P ＜ 0.01) in the control HaCaT cells,respectively.Conclusions PA can accelerate the proliferation of HaCaT cells,enhance NF-κB nuclear transfer,PPARα expression and IL-6 secretion in a dose-dependent manner within a certain concentration range,and may exert a promoting role in the activation and expression of some inflammatory factors.

0.5 cm or beneficial anatomical vari- ations displayed on MRCP,were obviously improved and there were no significantly different among the 4 types hilar eholangiocarcinoma.Conclusion MRCP could accurately make the preoperative diagnosis and type of hilar cholangiocarcinoma; the image of second branch of bile duct and the variation of the confluence of hepatic hilar displayed on MRCP has great clinical significance for operative regimes of hilar cholangiocar- cinoma,especially for typeⅣ.It does benefit not only to improve the resection and radical rate of some hilar cholangiocarcinomas, but also to select suitable method of biliary enteric anastomosis and avoid injuring the bile duct in operation.

ObjectiveTo investigate the association between the common variant rs1512268 single nucleotide polymorphism(SNP) of NKX3.1 gene and the risk of prostate cancer,and to explore its interaction with related risk factors.MethodsTotally 122 patients with prostate cancer and 105 age matched male people (prostatic specific antigen ＜ 4 μg/L,without family history of prostate cancer) as control group were enrolled.Polymerase chain reaction - high resolution melting curve(PCR - HRM) combined with gene sequencing methods were used to determine the distribution of allele and genotype frequencies of the rs1512268 SNP.ResultsThe distributions of GG,AG,AA genotypes were 42 cases(33.4％),66 cases(54.1％),14 cases(11.5％) in patients with prostate cancer,and 45 cases(42.9％),51 cases(48.6％),9 cases(8.6％) in healthy control,respectively.There were no significant differences in the distribution of genotype(x2 =1.70,0.69,0.52) and allele frequency (x2 =1.575) between the two groups(P＞ 0.05).The different genotypes of rs1512268 of NKX3.1 gene were not associated with age,Gleason score,PSA levels and clinical stage of prostate cancer (P＞0.05). Conclusions rs1512268 SNP of NKX3.1 gene is not obviously associated with prostate cancer and may be not the genetic risk factor in Chinese.

This article introduced the experience of Professor YU Yun in treating the primary carcinoma of liver by using acupuncture after pulse diagnosis. Professor YU thinks that the overall pathogenesis of liver cancer is deficiency of zang-fu organs, so the cancer cells can invade and occupy in the liver. Therefore, Professor YU uses the way of supporting the healthy qi and driving out the cancer as the treatment principle from multiple organs and meridians. On the basis of the theories of Nei Jing, Professor YU creates the acupuncture after pulse diagnosis. He feels the pulse on the basis of four pulses: Cunkou, Renying, Chongyang, and Taixi. According to the feelings of the pulses, he compares the size and speed, strong or weak, smooth or nonfluency of the four pulses. In treatment, he uses reducing method when the pulse is strong and fast, and tonic method when the pulse is weak and slow. He chooses the main acupuncture points on head, face, belly, flank and lower limbs. According to the experience, Professor YU uses gold needle in tonic method and uses silver needle in reducing method. In this way, the acupuncture after pulse diagnosis can regulate zang-fu organs and meridians, yin and yang, qi and blood, and promote blood circulation for removing blood stasis and resolving dampness, and attack the retained fluid and tumour in the liver, and combined with adjunct points to treat cancer.
