Objective To discuss the influence of Open resetlogs on Oracle database recovery. Methods Database backup was used to recover database before resetlogs. Before Oracle 9i, Oracle database was recovered through two steps; after Oracle10g, Oracle archived redo log by new format. Results Both methods could recover Oracle database by using backups before resetlogs. Conclusion Before Oracle9i, the recovery steps are complex, so it is suggested a consistent database backup should be made after resetlogs. By using the new archived redo log format after Oracle10g, it is easy to recover database through resetlogs.

BACKGROUND:Upright rat intervertebral disc degeneration model can prove that intervertebral fusion can aggravate the adjacent-segment intervertebral disc degeneration, but cannot affirm that spinal non-fusion technology has more advantages. OBJECTIVE:Base on the affirmed intervertebral disc degeneration models of Beagle dog, we performed intervertebral fusion to affirm whether or not the intervertebral fusion can aggravate the adjacent-segment intervertebral disc degeneration. METHODS:Twelve Beagle dogs were randomly divided into two groups. The control group animals were stabbed percutaneous to injure L5/6 disc. The experimental group animals were stabbed percutaneous to injur L5/6 disc. One month later, we made L4/5 intervertebral fusion. At 3 and 6 months postoperatively, lumbar MRI was conducted. L5/6 discs were harvested and subjected to histological observation and PCR. RESULTS AND CONCLUSION:(1) MRI:in the experimental group, 3 and 6 months after fusion, different degrees of intervertebral disk herniation appeared. In the control group, no obvious intervertebral disk herniation appeared. (2) Histological observation:6 months after fusion, in the experimental group, intervertebral disc annulus and nucleus pulposus were disordered;there was a gap in the fold, and the number of nucleus pulposus cel s decreased. In the control group, nucleus pulposus and anulus fibrosus boundary was clear;col agen was loose and arranged regularly. Cel number was more. Anulus fibrosus was close to normal. Col agen fibers were regular and dense. In the experimental group, 3 and 6 months after fusion, type II col agen-positive cel s were less than the control group (P<0.05). Moreover, type II col agen-positive cel s were less at 6 months than at 3 months in the experimental group (P<0.05). (3) PCR:Bone morphogenetic protein 15 and tissue inhibitor of matrix metal oproteinase 1 gene expression was higher in the experimental group than in the control group at 3 and 6 months after fusion (P<0.05). Bone morphogenetic protein 15 and tissue inhibitor of matrix metal oproteinase 1 gene expression was higher in the experimental group at 6 months than that at 3 months (P<0.05). (4) These results suggest that intervertebral fusion can aggravate the adjacent-segment intervertebral disc degeneration.

Objective:To establish a method based on the iPLEX analysis of MassARRAY mass spectrometry platform to detect multiplex genetic mutations among Chinese lung cancer patients. Methods:We reviewed the related literature and data of lung cancer treatments. We also determined 99 mutation hot spots in 13 target genes, namely, EGFR, KRAS, ALK, FGFR1, FGFR2, FGFR3, PIK3CA, BRAF, PTEN, MET, ERBB2, AKT1, and STK11, which are closely related to the pathogenesis, drug resistance, and metastasis of lung cancer and are associated with relevant transduction pathways. A total of 297 primers comprising 99 paired forward and reverse amplification primers and 99 matched extension primers were designed by using Assay Design in accordance with the mutation label and format requirements of the MassARRAY platform. The detection method was established by analyzing eight cell lines and six lung cancer specimens;the proposed method was then validated through comparisons with a LungCarta kit. The sensitivity and specificity of the proposed method were evaluated by directly sequencing EGFR and KRAS genes in 100 lung cancer cases. Results:The proposed method could detect multiplex genetic mutations in the lung cancer cell lines, and this finding is consistent with that observed using previously reported methods. The proposed method could also detect such mutations in clinical lung cancer specimens;this result is also consistent with that observed by using the LungCarta kit. However, an FGFR2 mutation was detected only by using the proposed method. The measured sensitivity and specificity were 100%and 96.3%, respectively. Conclusion:The proposed MassARRAY technology-based method could detect multiplex genetic mutations among Chinese lung cancer patients. Indeed, the proposed method can be potentially applied to detect mutations in cancer cells.

Objective:To explore whether the phospholipidoproteinaceous material deposit within the alveoli by a high-ifeld 3T MRI has signal characters and its application for diagnosing pulmonary alveolar proteinosis.Methods:A total of 11 patients with pulmonary alveolar proteinosis previously diagnosed by ifberoptic bronchoscope lung biopsy underwent 64-slice helical CT scans and 3T MRI scans, and the CT scans and the MRI scans were compared.
Results:hTe phospholipidoproteinaceous material deposit within the alveoli presented longer or equal T1 relaxation time and longer T2 relaxation time, without characters of fatty or deposits of protein-like substance signals and enhancement. The distribution, form, number and size of the lesions at T2WI were almost the same as those at CT, the lesions were irregular in morphology, and there was a clear boundary between the lesions and the adjacent normal lung tissues. Dynamic contrast-enhanced MRI showed thickened pulmonary arteriolae and venulae in the lesions with more obviously thickened pulmonary venulae, which were in conformity with the pulmonary artery and venule enhancement. CT scan in 1 out of the 11 cases showed lesions in both lungs mainly consisted of stripe-shaped and reticular structures, and no obvious sign of pulmonary alveolar proteinosis residue was found. MRI scan detected alveolar proteinosis that failed to be shown by CT scan.
Conclusion:3T MRI T2WI can easily detect the lesions of long T2 signals formed by the lipoproteinaceous material deposit within the alveoli. In the lesions, geographic appearance was presented, and the crazy paving pattern was dimly visualized. MRI can relfect the morphological characters of PAP like CT and it is slightly better compared with CT in such aspects as evaluating the theraputic effect of lung lavage. As supplement to CT, high-field 3T MRI can serve as an important examination for lung diseases.
