Objective High expression of the valosin-containing protein ( VCP) gene can enhance the metastasis of osteosar-coma via the AKT/PI3K/NF-KappaB/MMP-9 signaling pathway, but the molecular mechanisms underlying the up-regulation of VCP in osteosarcoma cells remains unknown .This study aimed to determine whether miRNA-129-5p can regulate the VCP expression and its targets in human osteosarcoma cells . Methods The microRNA target-predicting software TargetScanhuman 6.2 ( http://www.tar-getscan.org/) was used to predict the possible targets of miRNA-129-5p on the VCP gene.Then, two recombinant gene report vectors containing the wild VCP gene 3′UTR ( psi-VCP vector ) and mutant VCP gene 3′UTR ( psi-VCPmut vector ) were constructed , se-quenced, and identified.The human osteosarcoma U2-OS cells were co-transfected with miRNA-129-5p mimic and psi-VCP vector or psi-VCPmut vector, respectively.A non-specificity mimic transfection served as negative control , and the luciferase activity was detec-ted in each group. Results The software prediction showed only one conserved function site of miRNA-129-5p on the VCP gene 3′UTR163-169 bp.Luciferase activity was significantly lower in the psi-VCP vector +miRNA-129-5p transfection group (15.529 ± 1.902) than in the VCP control group (21.781 ±0.854), VCP mutation experimental group (19.978 ±1.377), and VCP mutation control group (21.952 ±1.516) (P<0.05), with no remarkable difference between the VCP mutation control and VCP control groups (P=0.276). Conclusion miRNA-129-5p can probably regulate the targets of the VCP gene in human osteosarcoma U 2-OS cells.

Objective To investigate the effects of down-regulating phosphorylated human epidermal growth factor receptor 2 (HER2) on the proliferation and metastasis in human osteosarcoma cells (U2-OS) in vitro. Methods Various concentrations of HER2 phosphorylation inhibitor lapatinib ditosylate (5, 10, 20, 30 and 40 μmol/L) were adopted to deal with U2-OS. MTT assay was performed to evaluate the cell proliferation during various times (24, 48 and 72 h), and the IC50 value in 24 h was calculated. The value of 10μmol/L (IC50=22.15μmol/L) was chosen to deal with U2-OS cells. The expres-sion level of phosphorylated HER2 (p-HER2) was measured by Western blot assay. The cell migration and invasion abilities were detected by Wound healing and Transwell invasion assays. Results The cell proliferation of U2-OS was significantly inhibited by HER2 phosphorylation inhibitor lapatinib ditosylate in a concentration- and time-dependent manner. During 24 hours, the p-HER2 level was significantly lower in lapatinib ditosylate group than that of negative control group (0.093± 0.033 vs 0.306±0.033), the cell migration rate was significantly lower in lapatinib ditosylate group than that of negative con-trol group (32.70%±3.00%and 94.52%±4.76%), and the trans-membrane cells were significantly lower than those of nega-tive control group (37/HP±5/HP and 85/HP±10/HP), respectively. Conclusion The down-regulating p-HER2 in U2-OS could efficiently inhibit the cell proliferation, migration and invasion in vitro. HER2 has the potential to become a molecular target for anti-osteosarcoma metastasis.

Artificial anus is the important surgical treatment for low colorectal cancer. However, fecal incontinence caused by artificial anus has significant influence on quality of life of patients. A series of novel therapy devices have been invented to solve the problem. According to the different applying methods, these devices can be divided into artificial sphincter and occluder. Artificial sphincter is implanted surgically and more automatic but its complicated design increased risk of complications such as infection and gastrointestinal symptoms. By comparison, occluder is less automatic and needs daily cleaning or replacement, but more comfortable, concealed and safer. For most of occluder are disposable or replaced frequently, advanced devices will greatly increase the economic burden on patients. With the progress of science and technology, artificial anal devices will become more intelligent, automatic and miniaturization.

Objective To investigate the efficacy and safety of domestic oseltamivir in patients with influenza. Methods A randomized, single-blinded, controlled clinical trial was performed.Patients in the study group received domestic oseltamivir, while the patients in control group received foreign oseltamivir. The doses were both 75 mg every time, twice a day. The treatment durations in both groups were 5 days. Chi square test was performed to compare baseline characteristics and the difference of side effects. Paired t test was used to compare the efficacy. Results Two hundred and nine patients were enrolled in this study (98 cases in study group. 111 cases in control group). The trend in body temperature change was similar in the two groups (t = 0. 061, P>0. 05). The score of symptom severity decreased more quickly in patients treated with foreign oseltamivir compared to those treated with domestic oseltamivir during the period from 24 h to 48 h. However, the difference between the two groups diminished gradually and was not statistically significant at 72 h (t=0. 875,P>0. 05). The safety of the domestic and foreign oseltamivir were comparable(X2 = 0. 197,P>0. 05). Conclusion The domestic oseltamivir is as effective and safe as the foreign oseltamivir.

Colorectal cancer (CRC) as a common malignancy in the digestive tract, its incidence and mortality increase significantly in China. Cancer stem cells (CSCs) are defined as a small fraction of tumor initiating cells that are endowed with both self-renewal and tumor growth potential. They may be responsible for tumor progression, metastasis, relapse and drug-resistance. Therefore, the isolation and characterization of tumorigenic CSCs in CRC may help to devise novel diagnostic and therapeutic procedures. This review briefly discusses the most recent advances in research on colorectal cancer stem cells including definition of the cancer stem cells, origin and specific markers of the colorectal CSCs. Transduction signal pathway involved in CSCs, potential therapeutic strategies targeting CSCs, and current issues in CSCs related research are also discussed.

OBJECTIVETo study in vivo the endogenous self-repair mechanism in immature white matter induced by ischemia in neonatal rats with periventricular leukomalacia (PVL).

METHODSFive-day-old neonatal Sprague-Dawley (SD) rats were randomly divided into sham and PVL groups. Rat model of PVL was prepared by ligation of the right common carotid artery following 2 hours of exposure to 8% oxygen. Pathological changes and myelination in the white matter were assessed under light and electron microscopy at 7 and 21 days after PVL. O4-positive OL precursor cells in the white matter were determined with immunofluorescence staining. Activation, proliferation, migration and differentiation of glial progenitor cells in SVZ were observed using immunofluorescent double labeling of either NG2 (marker of progenitor cells) and 5-bromodeoxyuridine (BrdU), or O4 (marker of OL precursor cells) and BrdU.

RESULTSAll rats in the PVL group manifested either mild or severe white matter injury under light microscopy, and had higher pathological scores of white matter compared with the sham group at 7 and 21 days after PVL (P<0.05). Electron microscopy showed that the number and thickness of myelin sheath in the PVL group were significantly reduced compared with the sham group (P<0.01). O4-positive OL precursor cells in the white matter observed under fluorescence microscopy were significantly reduced in the PVL group compared with the sham group (P<0.05). BrdU/NG2-positive cells in the SVZ increased significantly in the PVL group 48 hours after PVL and migrated into the periventricular area, reaching a peak on day 7 after PVL. BrdU/O4-positive newborn cells began to appear in the periventricular area 72 hours after PVL, and the number of BrdU/O4-positive cells in the PVL group was statistically more than in the sham group on day 21 after PVL (P<0.05).

CONCLUSIONSIschemia may induce brain self-repair in neonatal rats, resulting in activation and proliferation of NG2 glial progenitor cells in the SVZ migration and differentiation into OL precursor cells in periventricular white matter.
