OBJECTIVE:To systematically review the efficacy and safety of ramucirumab in the treatment of adenocarcinoma in stomach or gastroesophagealjunction,and provide evidence-based reference for clinic. METHODS:Retrieved from Wanfang database,CJFD,PubMed,EBSCO,Medline and Cochrane Library,randomized controlled trials(RCT) oframucirumab and (or) other medicines or other chemotherapy (test group) versus placebo or and Clinical Trials. gov other antibiotics(control goroup) were collected with time limit from establishment to Sept. 2015. Meta-analysis was performed by using Rev Man 5.3 software after data extraction and quality evaluation by Cochrane systematic review manual 5.1.0. RESULTS:Totally 3 RCTs involving 1 188 patients were enrolled,including 652 patients in the test group and 536 patients incontrol group. Results of Meta-analysis showed, the overall survival[HR=0.83,95%CI(0.72,0.95),P=0.006] and progression-freesurvival[HR=0.66,95%CI(0.47,0.92),P=0.01] in test group were significantly longer than control group,the difference was statistically significant;there was no significant difference in the objective response rate[RR=1.31,95%CI(0.81,2.11),P=0.28]. The incidence of severe adverse reactions(degree level:3-4 grade) in test group was significantly higher than control group,the difference was statistically significant [RR=1.14, 95%CI (1.00,1.29),P=0.04].CONCLUSIONS:Ramucirumab can extend overall survival and progression-free survival of adenocarcinoma in stomach or gastro-oesophageal junction,but the incidence of adverse reactions should be noticed.

BACKGROUND: Previous studies demonstrate that interleukin 1β(IL-1β) plays a great role in the degeneration of articular cartilage in knee joints which was caused by the anterior cruciate lagement (ACL) rupture; however, the role of IL-1β in the degeneration of lateral meniscus remains poorly understood. OBJECTIVE: To investigate the changes and significance of the expression of IL-1βin the lateral meniscus of rabbits with ACL rupture. METHODS: A total of 48 male, New Zealand, white rabbits, were matched mode pairs and prepared for ACL rupture models. In the experimental side, the ateral meniscus of rabbits was cut down to prepare ACL rupture models, simultaneously, the control sides were exposed without cut down. A total of 12 rabbits were secdficed under anesthesia at weeks 1, 3, 6 and 8 after model preparation. Degeneration scores of lateral meniscus and expression of IL-1β in lateral meniscus were performed. RESULTS AND CONCLUSION: With time prolonged, the scores of lateral meniscus degeneration were increased, which was higher in the experimental group than those in the control group at each time points (P < 0.05). The positive rate of IL-1β was greater in experimental group than that in the control group (P < 0.05). In addition, the positive rate of IL-1β in the experimental group was greater at weeks 3 and 6 than weeks 1 and 8 (P < 0.05), which was higher in week 8 than week 1 (P < 0.05). The results demonstrated that the highly expressed IL-1β in the experimental sides hints that IL-1β maybe a promotional factor which causes the degeneration of lateral meniscus. The decreasing of the expression of IL-1β is not a stopping signs of lateral meniscus degeneration.

Objective To assess the efficacy and safety of different dosages of oxycodone plus acetaminophen for treating acute pain after oral surgery,in order to provide a reasonable dosage of combination in clinic. Methods Randomized controlled trials ( RCTs ) on effect of combination of oxycodone plus acetaminophen on pain relief after oral operation were searched from the following data-bases:PubMed,EMbase,MEDLINE ( Ovid) ,the Cochrane Library,CNKI,and WANFANG from the date of their establishment to January 2015. The data of RCTs meeting the inclusive criteria were extracted according to Cochrane methods by two reviewers independently,and after the quality was evaluated and cross-checked,meta-analyses were conducted using RevMan 5.2 software. Results A total of 11 studies in 10 literatures involving 1 028 patients were included and were designated to 3 different dosage groups (5 mg/325 mg,10 mg/650 mg,10 mg/1 000 mg,respectively). The results of Meta-analyses showed that pain remission rate was significantly higher in the 3 different dosages of oxycodone plus acetaminophen groups than in the placebo group (RR5 mg/325 mg=3.35,95%CI [1.74,6.45],I2=38%,P=0.000 3;RR10 mg/650 mg=6.88,95%CI [4.00,11.83],I2=0%,P<0.000 01;RR10 mg/1 000 mg=4.94,95%CI [3.23,7.56],I2=81%,P=0.005). In additional,the RR of oxycodone 10 mg/acetaminophen 650 mg and placebo groups for pain remission rate was higher than that of the other 2 dosages groups,moreover,more studies were enrolled and its low heterogeneity led to high reliability. Usage rate of remedial painkillers was significally lower in oxycodone plus acetaminophen groups than in the placebo group (RR5mg/325mg=0.71,95%CI [0.60, 0.85],P<0.000 01;RR10mg/650mg=0.50,95%CI [0.41,0.61],P<0.000 01;RR10mg/1000mg=0.77,95%CI [0.66,0.90],P=0.001) ,In addition, the RRs of usage rate in oxycodone 10 mg/acetaminophen 650 mg and placebo groups were significantly lower than the other 2 dosages groups. Incidence rates of adverse effects were similar in the 3 different dosages groups and higher than that of the placebo group. However,the adverse events were generally described as mild to moderate in severity and rarely led to drug withdrawal according to all reports in the studies ( only one event ) . Conclusion The present study showed that combination of oxycodone plus acetaminophen can provide better analgesia in acute pain after oral surgery with high safety. In addition,combination of oxycodone 10 mg plus paracetamol 650 mg may be better for acute pain relief after oral surgery.

Objective To reveal the influential factors on scalp electroencephalogram (EEG)recording and provide valuable information for localization of the epileptic focus by analyzing the characteristics of spikes with continuous focal periodic discharges on scalp and cortical EEG. Methods Five patients with refractory epilepsy who had low amplitude spikes with continuous focal periodic discharges on interictal scalp EEG were studied. Intracranial EEG recording was also performed in patients. The amplitudes of spikes and cortical areas of spike-wave foci were measured by DaVinci system. Patterns of continuous periodic activity were determined by autocorrelograms,power spectral density and coherence analysis using Matlab and Spike2 software.T-test was employed to compare the mean amplitudes of spikes on the scalp and cortical EEG.Results The amplitudes of spikes recorded on scalp EEG of the 5 patients were:(22.2±4.8),(30.4±7.1),(20.7±3.2),(58.4±10.1),(23.4±3.9) μV.The amplitudes of spikes recorded on cortical EEG of the 5 patients were:(1253.8 ± 199.3),(806.5 ± 161.4),( 1585.7 ±305.7),(922.5 ± 140.6),(736.8 ±70.9) μV.The amplitudes of spikes on scalp EEG were significantly higher than those on cortical EEG ( t =6.394,P ＜ 0.05 ).The cortical areas of spike-wave foci of the 5 patients were:4.0,6.0,3.5,5.5,6.5 cm2.Power spectral density and autocorrelugrams showed 1-3 Hz oscillations on the cortical of spike-wave foci. Cross-correlation and coherence analysis showed synchronization of electrical activity in two contacts of intracranial electrodes. Conclusion The low amplitude spikes with continuous focal periodic discharges on interictal scalp EEG provide valuable information for localization of the epileptic focus.

AIM:To study the differentiation of rat marrow-derived mesenchymal stem cells(MSCs) into myoid cells in vitro . METHODS:The MSCs of SD rat were cultured?passaged?induced and differentiated in vitro used by routine culture technique, and evaluated by FACScan flow cytometer,detected by immunohistochemistry and analyzed by Hitachi H-600 transmission electron microscope(TEM). RESULTS:FACScan shows that cells expressed the antigens of CD29 and CD44, not those of CD11b and CD45; cells show positive response of staining with desmin and myoglobin after processing by two compounds of 5-azacytidine and amphotericin B. There were stripform zone of myofilament without any organells beside the edge of membrane in myoid cell of induction and differentiation checked by TEM. CONCLUSION: The passaged cells were MSCs and the MSCs may have specific gene structures that can differentiate into myoid cells. The demethylation or hypomethylation may conduct by compounds of 5-azacytidine and amphotericin B, which could be involved in activating phenotype-specific genes to differentiate MSCs into myoid cells. There are good outlook on clinical treatment of illness of myatrophy using by MSCs.
