PURPOSE: Hepatocellular carcinoma (HCC) is a common cancer worldwide. Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), a long noncoding RNA (lncRNA), has been reported to be aberrantly expressed in hypoxic cancer cells. MALAT1 plays a significant role in many malignancies, including HCC. The aim of this study was to explore the role of MALAT1 in hypoxic HCC cells and its underlying regulatory mechanism. MATERIALS AND METHODS: Quantitative reverse transcription PCR (qRT-PCR) assay was performed to detect the mRNA levels of MALAT1 and microRNA-200a (miR-200a) in HCC cells. Cell invasion and migration ability were evaluated by Transwell assay. Starbase v2.0 and luciferase reporter assay were employed to identify the association between MALAT1 and miR-200a. Cell proliferation and apoptosis were measured by MTT assay and flow cytometry, respectively. RESULTS: MALAT1 levels were significantly upregulated in HCC cells under hypoxia. Hypoxia promoted proliferation, migration, and invasion, and blocked apoptosis in Hep3B cells, which were weakened by knockdown of MALAT1. Starbase v2.0 showed that MALAT1 and miR-200a have a complementarity region, and luciferase reporter assay verified that MALAT1 interacted with miR-200a in Hep3B cells. Moreover, MALAT1 negatively regulated the expression of miR-200a. miR-200a levels were dramatically downregulated in HCC cells under hypoxia. Upregulation of miR-200a inhibited proliferation, migration, and invasion, and induced apoptosis in Hep3B cells under hypoxia. Interestingly, downregulation of miR-200a partially reversed the tumor-suppressive effect of knockdown of MALAT1 on Hep3B cells in hypoxic condition. CONCLUSION: LncRNA MALAT1 was involved in proliferation, migration, invasion, and apoptosis by interacting with miR-200a in hypoxic Hep3B cells, revealing a new mechanism of MALAT1 involved in hypoxic HCC progression.

Objective To investigate the risk factors of proximal junctional kyphosis (PJK) after posterior long segmental lumbar fusion for degenerative lumbar disease. Methods From October, 2012 to July, 2014, 118 degenerative lumbar disease patients who accepted posteri-or long segmental fusion and followed up at least 1.5 years were reviewed. All the PJK were evaluated with X-ray. Results Sixty-six pa-tients completed the follow-up (mean of 3.2 years), in which 12 patients with PJK (PJK group), and the others without (non-PJK group, n=54). There was significant difference in body mass index, bone density and the last Oswestry Disability Index scores (t>2.194, P<0.05) be-tween both groups, as well as the rate of the upper instrumented vertebra (UIV) located in the thoracolumbar segment (T11-L1) (χ2=4.63, P<0.05). The PJK angle was more in PJK group than non-PJK group pre-surgery, post-surgery and finally (t>3.862, P<0.001). Binary Logistic regression showed that osteoporosis (OR=5.328, 95% CI: 1.110~25.581), UIV located in the thoracolumbar segment (T11-L1) (OR=6.239, 95%CI:1.157~33.648) and the pre-surgery PJK angle>10° (OR=5.789, 95%CI:1.075~31.183) were the independent risk factors of PJK. Conclusion Osteoporosis, UIV located in the thoracolumbar segment (T11-L1) and the pre-surgery PJK angle>10° are risk factors of PJK af-ter posterior long segmental lumbar fusion.

OBJECTIVETo investigate possible differences in the prognosis in children with severe nocturia who received different drug withdrawal schedules.
METHODSNinety-seven children with severe nocturia were randomly assigned to two groups: control (n=47) and observed (n=50). The control group accepted drug withdrawal immediately, while the observed group accepted dose tapering gradually after a 12-week treatment course. The frequency of enuresis was observed three months after complete drug withdrawal.
RESULTSDuring the treatment, the frequency of enuresis in all of children from both the control and the observed groups was reduced by over 90%. Forty-six children (92%) from the observed group showed the frequency of enuresis was reduced by over 90%, but 28 children (60%) from the control group (p<0.01) three months after the complete drug withdrawal. There were no significant differences in the adverse effect and the medication compliance between the two groups.
CONCLUSIONSThe different schedules of drug withdrawal may lead to different prognosis, and the schedule of gradual drug withdrawal may be superior to the immediate one in children with nocturnal enuresis.
