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.

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 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.

Objective To observe the protective effects of mycelium of cultured Cordyceps sinensis on testis in diabetic Wistar rats. Methods 21 rats were divided into control group(C), diabetes group(D) and treatment group (T) at random. Diabetic model was reproduced by intraperitoneal injection of alloxan. After having been treated with Jinshuibao capsule for 8 weeks, serum levels of glucose, insulin, testosterone and levels of high energy phosphate compound, MDA, SOD, GSH-Px, and ATPases in the testis were determined respectively. Results Compared with control group, testicular mitochondria showed lipid peroxidase injury, with disturbed energy metabolism, and the activity of ATPases was lowered. All the changes in serum and testes were improved when Jinshuibao capsule was given. Conclusion Mycelium of cultured Cordyceps sinensis might have protective effects on the testis in diabetic Wistar rats.

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.

[ ABSTRACT] AIM: To observe the effect of microRNA-19a ( miR-19a) on the lipid catabolism of hepatocyte LO2, and to explore the potential mechanism.METHODS: miR-19a was over-expressed or silenced by transfection of miR-19a mimics or miR-19a inhibitor into LO2 cells, then the mRNA level of miR-19a was detected by real-time PCR.The potential target of miR-19a was found by the method of bioinformatics through internet website.The effect of miR-19a on the 3’ UTR of peroxisome proliferator-activated receptorα(PPARα) was measured by dual luciferase reporter assay, and the protein level of PPARαand its 2 major downstream rate-limiting enzymes involved in lipid catabolism, acyl-coenzyme a dehydrogenase (ACADM) and carnitine palmitoyltransferase 1A ( CPT1A), were detected by Western blotting.Mean-while, the effect of miR-19a on the generation of ketone body was measured by beta-hydroxybutyric acid (β-OHB) detec-tion assay.RESULTS:The mRNA level of miR-19a was dramatically elevated by the transfection of miR-19a mimics, and sharply decreased by the transfection of miR-19a inhibitor (P<0.05).PPARαwas found as a potential target of miR-19a, and dual luciferase reporter assay and Western blotting confirmed the regulatory effect of miR-19a on the expression of PPARα, with the protein level changes of ACADM and CPT1A.miR-19a mimics down-regulated, while miR-19a inhibitor up-regulated the concentration ofβ-OHB in LO2 cells (P<0.05).CONCLUSION:miR-19a regulates the lipid catabo-lism of hepatocytes by targeting the PPARαand its 2 downstream rate-limiting enzymes.

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.
