2.Comparison of the analgesic efficacy between the epidural and intravenous analgesia after spinal fusion:a Meta-analysis
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 To investigate the renal function of the patients with acute myocardial infarction (AMI) and its effect on patients' outcome.Methods The renal function of 680 patients with AMI,received the conventional therapies, such as thrmbolysis, antiplatelet and antianginal therapies were investigated. According to it, 228 patients with renal dysfunction[GFR <90ml · min-1 · ( 1.73m2 ) -1]were divided into observation group,while the others[GFR≥90ml · min-1 · (1.73m2) -1]were divided into control group. To analyse their clinical characteristics、the inhospital mortality、one year mortality and the heart ocurrence rate in one year. Results Compared with the patients in the control group,the patients in the observation group were older、more likely to be women、and more likely to have hypertension、diabetes mellitus、coronary heart disease. The inhospital and one year mortality were higher ( 17. 8% vs 9.74% ,P <0. 01 ;25.00% vs 14. 44% ,P <0. 01 ) and the heart ocurrence rate was higher(57. 14% vs38. 96% ,P < 0. 01 ) in one year in the observation group than that in the control group. ConclosionThe AMI patients with renal dysfunction were more likely to have concomitant diseases, worse ill condition and outcome. Renal dysfunction was an independent risk factor for the outcome in the patients with AMI.

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.

Objective To observe the brain abnormalities of the white matter and myelination in patients with BH4 deficiency using MRI examination, and to further estimate the effect of treatment. Methods Eleven patients with BH4 deficiency aged 17 weeks to 4 years were observed, including 9 cases who were detected by newborn screening program. Although those patients were treated with low phenylalanine diet, and the blood phenylalanine 1evels maintained to 120-240 ?mol/L, the patients presented progressive hypotonia, convulsion, and mental retardation. All cases were diagnosed as BH4 deficiency by analysis of urinary pterins profile, BH4 loading test, and determination of dihydropteridine reductase in RBC. The patients received MRI examination using a 0.5 T MR system. Results Delayed myelination was found in 11 cases (100%) in frontal lobe, 8 cases (72.2%) in occipital lobe, 4 cases (36.3%) in temporal lobe, and 3 cases (27.3%) in parietal lobe. Delayed myelination of corpus callosum could be found in 6 cases (54.5%). There were abnormal diffuse high signals in the white matter on T_2WI in all cases. Conclusion Patients with BH4 deficiency demonstrate a high occurrence of brain abnormalities in the white matter. Those abnormalities are related not only with hyperphenylalaninemia, but also due to the decreased synthesis of neurotransmitters, such as L-Dopa and 5-HTP, all of these could be the reasons of adverse effect of the development of white matter.
