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 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 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.

BACKGROUND:Previous studies have demonstrated that amblyopic patients have a variety of dysopsia compared with normal people.Engineered visual system could find amblyopia through detection of human visual system.OBJECTIVE:To screen sensitive indexes for amblyopia through visual function examination to establish a intemet-based amblyopia screening method.DESIGN,TIME AND SETTING:Randomized,blinded,and controlled experiment.The study was performed at Department of Optometry,People's Hospital of Guangxi Zhuang Autonomous Region from September to November 2008.PARTICIPANTS:A total of 80 volunteers undergoing visual examination in Department of Optometry,People's Hospital of Guangxi Zhuang Autonomous Region were selected,aged 4-19 years.All people had no organic diseases of eyes.They were divided into normal group (n=40) and ambiyopic group (n=40) according to their corrected visual acuity (whether ＞ 4.9).METHODS:Using vision system,the various visual function indexes of each participant were examined.The data from single eye and both eyes were collected and analyzed using Fisher.The sensitive indexes were selected to establish identification function for amblyopia screening.MAIN OUTCOME MEASURES:Age,visual noise,orientation identification and contour integration of participants were examined.RESULTS:Results showed that age,visual noise,orientation identification and contour integration were clinically significant indexes,and cross validation suggested that the identification correct rate was 92.5%.The discriminant function of amblyopia was Y1=1.175X1+0.786X2+0.928X3+1.061X4-0.225X5+2.547X6+1.313X7-18.651;the discdminant function of normal vision was Y2=1.369X1+ 1.728X2+1.779X3+1.549X4-1.912X5+2.665X6+0.387X7 26.640.CONCLUSION:Visual noise,orientation identification and contour integration in vision detection system could be used to screen amblyopia in children,in particular with assistance of internat.

Objective To assess the feasibility of laryngeal mask anesthesia under spontaneous ventilation in pulmonary resection with uniportal video-assisted thoracoseopic.Methods Forty patients with pulmonary masses were randomized into two groups(n =20 in each group) to undergo pulmonary resection with uniportal videoassisted thoracoscopic,full implementation of thoracoscopic lobectomy and mediastinal lymph node dissection.Patients in two groups were induced by intravenous anesthesia,and the skin of the fifth intercostal space were infiltrated with ropivacaine.Patients in two both groups were maintained by intravenous ancsthesia and sevoflurane anesthesia.Muscle relaxants were administered in endotracheal inmbation group but not in the LMA group.Patients in the LMA group and tracheal intubation group underwent with spontaneous breathing and one-lung ventilation respectively.Results No significant differences were found in surgery time,intraoperative lowest SpO2,preoperative PaCO2,1-h postoperative blood gas analysis between the two groups.The anesthesia induction time,extubation time,and the stay time for the recovery of anesthesia and postoperative hospital stay were significantly shorter than those in the tracheal intubation group.The increments in MAP and HR after intubation operation were smaller than those in the LMA group.The total dosage of sulfentanyl and propofol per kg in the LMA group were significantly less than those in the control group.The PaCO2 after pulmonary resection and the intraoperative maximum level of PETCO2 in the former group were significantly higher than those in the tracheal intubation group,however the incidence of throat discomfort and the hospitalization cast were significantly decreased.Conclusion In view of patient rehabilitation and in hospitalization cast,laryngeal mask anesthesia under spontaneous ventilation in uniportal video-assisted thoracoscopic surgery was better than the procedure performed under intubation anesthesia.

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.
