Chinese Journal of Spine and Spinal Cord 2014;(5):433-439
Objectives: To compare the efficacy of patient-controlled epidural analgesia and patient-controlled intravenous analgesia in postoperative analgesia after spinal fusion. Methods: The CNKI, Wanfang, CBM, Pubmed, Embase, Ovid, Cochrane library databases were searched by computer. The randomized controlled trails with patient-controlled epidural analgesia or patient-controlled intravenous analgesia after spinal fusion published from May 1985 to July 2013 were selected. All of them were assessed by the standard of Cochrane systematic review. Data of postoperative VAS and the rate of side effects after using the analgesic drugs were extracted into an electrical sheet, which was synthesized by a Meta-analysis with RevMan 5.2 software. Re-sult: Eight randomized controlled trails involving 482 patients met the inclusion criteria. And the quality grade of 3 literatures was A, 5 literatures was B. The result of meta-analysis showed that: ①Visual analogue score(VAS). The postoperative first day′s VAS[WMD=-0.47, 95%CI(-0.74, -0.20)], second day′s VAS[WMD=-0.66, 95%CI(-1.14, -0.19)] showed that the patient-controlled epidural analgesia had a good analgesic effect compared with the patient-controlled intravenous analgesia, and both had statistic differences(P<0.05). No dif-ference in the postoperative third day′s VAS[WMD=-0.58, 95%CI(-1.38, 0.21)] was observed between the two methods, and no statistic difference(P>0.05); ②The side effects. The patient-controlled epidural analgesia had a higher incidence of skin itch[RR=1.53, 95%CI(1.08, 2.16)], paresthesia[RR=3.34, 95%CI(1.12, 9.98)] after surgery than the patient-controlled intravenous analgesia, and both had statistic differences(P<0.05). While two groups had no a significant deviation about nausea [RR=1.05, 95%CI (0.79, 1.40)], vomiting [RR=0.80, 95%CI (0.48, 1.31)], and no statistic difference(P>0.05). Conclusions: The patient-controlled epidural analgesia has better analgesic effects on the postoperative first and second day after spinal fusion, but obviously has a high-er incidence of skin itch and paresthesia than the patient-controlled intravenous analgesia.

Objective To determine the anatomical and visual outcome of indocyanine-green (ICG)-assisted internal limiting membrane (ILM) peeling for idiopathic macular holes. Methods Thirty-one eyes of 31 patients with 3- (14 eyes, 45.2%) and 4-staged (17 eyes, 54.8%) primary idiopathic macular holes were analyzed. All the patients underwent the subtotal pars plana vitrectomy with removal of the posterior vitreous. ICG solution with the concentration of 1.25 mg/ml was injected into vitreous cavity. The ILM was stained and removed in a circular fashion of 2 to 3 disc-diameter from the edge of the hole. At the end of the surgery, 14% C 3F 8 mixed gas was used and the patients were required to maintain a prostrate posture for two weeks postoperatively. The mean follow-up duration was 9.1 months. Results The preoperative median visual acuity was 20/200. In the final follow-up, 28 eyes (90.3%) had anatomical restoration of the macular holes, 21 eyes had improvement of two lines or more of visual acuity. There was no direct complication or toxicity related to ICG-assisted ILM peeling except one patient with retinal detachment caused by peripheral retinal hole. Conclusion ICG-assisted retinal ILM removal appears beneficial and safe for primary idiopathic 3 and 4-staged macular holes.

Esophageal cancer is a cause of cancer mortality and accounts for the sixth most common cause of cancer-related death. The focus of recent study has shifted towards testing novel agents that target specific molecular abnormalities known to occur in esophageal squamous cell carcinoma (ESCC). The preclinical studies involving various cancer models, including ESCC, epidermal growth factor receptor (EGFR) over-expression, are linked to epithelial cell proliferation, differentiation and migration, and have an inverse relationship to tumor chemotherapy curability. Nimotuzumab is a humanized anti-EGFR monoclonal antibody that binds to the extracellular domain of the EGFR and inhibits EGF binding. In many phase Ⅱ trials, nimotuzumab showed marked antiproliferative, proapoptotic and antiangiogenic effects in tumors that overexpress EGFR. Some phaseⅢtrials are ongoing.

Objective Scutellarin (SCU), a Chinese traditional medicine, has a protective effect against ischemia-reperfusion (IR) induced myocardial injury, but it is not yet clear whether SCU acts against vascular endothelial IR injury via extracellular signal-regulated kinase 1/2 (ERK1/2).The aim of this study was to explore the effect of SCU on hypoxia-reoxygenation (HR)-induced injury to human cardiac microvascular endothelial cells (HCMECs) and its influence on the ERK1/2 signaling pathway.Methods HCMECs were subjected to normal culture and divided into a normal control, a DMSO, an SCU 1 μmol/L, and an SCU 10 μmol/L group.The model of HR injury was established by exposing the HCMECs to 12-h hypoxia and 12-h reoxygenation after treated with DMSO or SCU at 1 and 10 μmol/L for 2 hours.Then, the survival rate of the HCMECs was detected by MTT and trypan blue staining, the concentration of malondialdehyde (MDA) in the cells measured, and the expressions of the p-ERK1/2, ERK2 and GAPDH proteins determined by Western blot.Results SCU at 1 and 10 μmol/L significantly increased the survival rate of the normally cultured HCMECs ([110.40±2.34] and [122.00±1.25] %) as compared with that of the normal control (100%) (P<0.05), while HR injury markedly decreased the vitality of the HCMECs ([68.00±4.06] %) in comparison with that of the blank control (100%) (P<0.05).The survival rate of the HCMECs was remarkably higher in the HR+SCU 1 μmol/L and HR+SCU 10 μmol/L groups than in the HR model group ([90.53±3.67] and [92.04±2.32] %) (P<0.05), and so was their vitality in the SCU 10 μmol/L group than in the normal control ([96.78±2.01] vs [90.06±1.85] %, P<0.01), while their survival rate was significantly lower in the HR model than in the blank control ([73.72±4.91] vs [91.83±2.34] %, P<0.01) and remarkably higher in the SCU 10 μmol/L ([87.59±2.64] %) than in the HR model group (P<0.05).The MDA concentration in the HCMECs was markedly increased in the HR model and HR+DMSO groups as compared with the blank control (P<0.01), but decreased in the HR+SCU 1 μmol/L and HR+SCU 10 μmol/L groups in comparison with the HR model group (P<0.05).The expression of the p-ERK1/2 protein was significantly down-regulated in the HR model group as compared with the blank control (P<0.01), but up-regulated in the HR+SCU 10 μmol/L group in comparison with the HR model (P<0.01).Conclusion HR injury reduces the vitality of HCMECs, increases the MDA concentration, and down-regulates the expression of the p-ERK1/2 protein in HCMECs, while SCU acts against ischemia-reperfusion injury to HCMECs by increasing ERK phosphorylation.

Objective To investigate whether miR-200b suppresses proliferation and induces apoptosis of non-small cell lung cancer cells by targeting DNMT3A. Methods A qRT-PCR was employed for detecting the expression of miR-200b in different non-small cell lung cancer cells and human bronchial epithelial cells. A549 cells were transfected with miR-200b mimics, scramble, DNMT3A-siRNA and control-siRNA, respectively. The scramble and control-siRNA were served the negative control of miR-200b mimics and DNMT3A-siRNA, respectively. Western blot assay was conducted to detect the expression of DNMT3A protein in A549 cells. MTT and Annexin V/propidium iodide staining were employed to detect the proliferation ability and apoptosis rate of A549 cells. The effects of miR-200b mimics and DNMT3A-siRNA on the proliferation and apoptosis rate of A549 cells were compared between groups. Results Results of qRT-PCR showed that the expression of miR-200b was significantly down-regulated in A549, H1299, L78 and H460 cells than that of 16HBE cells. Among them, the most obviously reduction was found in A549 cells (P<0.05). Western blot assay showed that the level of DNMT3A protein was inhibited by restored miR-200b or knock-down DNMT3A in A549 cells. After transfection of miR-200b mimics or knock-down DNMT3A for 48 h, 72 h and 96 h, MTT showed that the OD values, which reflected the optical density of cell proliferation were significantly lower than those in the control group (P<0.05). Annexin V/propidium iodide staining showed that apoptosis rates of A549 cells after transfection of miR-200b mimics or knock-down DNMT3A were (23.33%±0.90%and 20.41%±0.70%), compared with the control group (5.28%± 0.55%and 5.68%±0.47%, P<0.01). Conclusion miR-200b suppresses cell proliferation and induces apoptosis by targeting DNMT3A in non-small cell lung cancer.
