Background and purpose:Inhibitor of apoptosis-stimulating protein of p53 (iASPP) is one of the ASPP family. It binds to p53 to inhibit the transcriptional activity of p53-target genes and cell apoptosis, which is asso-ciated with tumor formation. Previously, we found a new subtype of iASPP, iASPP splice variant (iASPP-SV), which is a nuclear protein containing 407 amino acid residues and can bind to p53, inhibiting p53 transcriptional activity. However, the relationship of iASPP-SV and breast cancer is still obscure. Therefore, the purpose of this research was to study the role of iASPP-SV on breast cancer tumorigenesis and progression.Methods:5’-rapid ampliifcation of cDNA ends (RACE) was used to identify the 5’-end of iASPP-SV mRNA in MCF-7 cells. HEK 293 cells were transfected with pFLAG-iASPP-SV and pFLAG-iASPP (828). Then Western blot was used to identify whether endogenous iASPP-SV was expressed in HEK 293 cells and 8 types of human tumor cell lines. This study established the stable clones of NIH 3T3 expressing FLAG-iASPP-SV and FLAG-iASPP (828). Cell proliferation assay, colony formation and soft agar colony formation assay were used to identify whether iASPP-SV and iASPP (828) can promote cell proliferation and iASPP-SV is an oncogene. Real-time lfuorescent quantitative polymerase chain reactive (RTFQ-PCR) was used to de-tect the levels of iASPP-SV and iASPP (828) mRNA in primary breast cancers. Luciferase assays were used to identify the relationships between iASPP-SV, iASPP (828), p53 and NF-κB p65.Results:The study identiifed that iASPP-SV was encoded by previously reported NF-κB p65 subunit (RelA)-associated inhibitor (RAI), and endogenously expressed in many human cancer cell lines. Analysis of cell proliferation, colony formation assay and soft agar assay for colony formation identiifed that similarly to iASPP (828), iASPP-SV promoted tumor cell proliferation and acted as an onco-gene. RTFQ-PCR result showed that the median values of iASPP-SV and iASPP (828) in breast cancers with wild-type p53 were more signiifcantly over-expressed than those of mutant p53. Luciferase assays showed that iASPP-SV and iASPP (828) could suppress NF-κB p65 transcriptional activity. Thus iASPP family may participate in the regulation of p53 and NF-κB activity, which imply that iASPP perhaps shows pro- or anti-survival activities when it interacts with different proteins.Conclusion:These ifndings indicate that iASPP-SV may be a potential target for breast cancer thera-py.

Objective To investigate the efficacy observation of transcranial direct current stimulation (tDCS)for improving the attention in patients with infarction in basal ganglia area. Methods Sixty consecutive patients with basal ganglia infarction admitted to the Department of Rehabilitation Medicine,the First Affiliated Hospital of Nanchang University from May 2015 to May 2016 were enrolled. They were randomly divided into either a control group or a test group according to the random number table (n = 30 in each group). The patients in both groups received routine rehabilitation training,and those in the test group received tDCS therapy synchronously,and the control group received the sham tDCS stimulation. The evaluations and analyses were conducted with the Montreal cognitive assessment (MoCA),d2 test of attention,and event-related potential-P300 (ERP-P300),respectively in all patients before intervention and 4 weeks after intervention,and they were compared between the groups. Results There was no significant difference before intervention between the two groups (all P > 0. 05). Compared with before intervention,the ERP-P300 latencies were reduced,the amplitudes were increased after intervention in the patients of the test group and the control group (all P < 0. 05). The MoCA total scores (the test group:22. 7 ± 2. 7 vs. 15. 5 ±
2. 4;the control group:17. 2 ±2. 5 vs. 15. 6 ±2. 3),attention dimension scores (the test group:4. 6 ± 1. 2 vs. 2. 4 ± 1. 6;the control group:3. 6 ± 1. 5 vs. 2. 5 ± 1. 5),and the total completion of d2 attention test task, total scores,and concentration degree scores (the test group:295 ± 31 vs. 250 ± 45,279 ± 38 vs. 223 ± 52, 97 ± 22 vs. 75 ± 25;the control group:276 ± 33 vs. 247 ± 45,257 ± 39 vs. 211 ± 56,84 ± 23 vs. 71 ± 24) were all increased (all P < 0. 05),and all the indexes of the test group were better than those of the control group (all P < 0. 05). Conclusion tDCS contributes to the improvement of the attention in patients with infarction in the internal capsule-basal ganglia region.

Objective: To explore the inhibitory effect of gallotannin (GLTN) on the proliferation of rat glomerular mesangial cells (GMC)induced by high sugar stimulation and the influence in the cell cycle of the rats, and to clarify the prevention effect of GLTN in the occurrence and development of diabetic nephropathy (DN). Methods:The experimental cells were divided into normal control group (D-glucose 5.5 mmol·L-1 ,NC group), high glucose group (D-glucose 30 mmol· L-1 ,HC group),high glucose + 5 mmol· L-1 3 - AB group (AB group),high glucose + 20 μmol·L-1 GLTN group (G20 group),high glucose + 40 μmol· L-1 GLTN group (G40 group).The proliferation of GMC in different groups at different time points (4,8,24,48 and 72 h)was observed by MTT assay.The changes of cell cycle of GCM under different culture conditions were examined by flow cytometry,and the expression levels of TGF-β1 and CTGF were detected by Western blotting method. Results:Compared with NC group,the proliferation levels of GMC in HC group were increased (P <0.01),and reached the peak at 48 h ;the percentage of S phase cells was increased (P <0.01).Compared with HC group,the proliferation levels of GMC in 3-AB group and GLTN group were significantly decreased (P < 0.01 ),and the percentages of S phase cells were decreased (P <0.01).Compared with NC group,the protein expression levels of TGF-β1 and CTGF in each drug group were increased (P < 0.05 or P < 0.01),but they were significantly lower than those in HC group (P < 0.01).Conclusion:GLTN can inhibit the proliferation of GMC under high sugar stimulation through arresting the cell cycle and down-regulating the expressions of TGF-β1 and CTGF and delay the occurrence and development of DN.
