Objective To compare the efficacy of rcmifentanil combined anesthesia and fentanyl or sufentanil combined anesthesia in patients undergoing cardiac surgery.Methods We searched the Coehrane library,PubMed,EMBASE,OVID and Chinese Biomedical Database for prospective randomized controlled trials involving the comparison of the efficacy of remifentanil combined anesthesia and fentanyl or sufentanil combined anesthesia in patients undergoing cardiac surgery.The quality of the studies was evaluated by the method recommended by Cochrane Collaboration.Evaluation indexes included the mechanical ventilation time after operation,duration of stay in hospital,and level of cardiac troponin,mortality,requirement for positive inotropic drugs and incidence of hyperalgesia and myocardial infarction during perioperative period.Meta-analysis was conducted using the RevMan 5.0 software.Results Sixteen prospective randomized controlled trials involving 1473 patients were included in our Meta-analysis.The patients were divided into 2 groups:fentanyl or sufentanil group ( n =644) and remifentanil group ( n =573).Compared with fentanyl or sufentanil group,the mechanical ventilation time after operation and duration of stay in hospital were significantly shortened,the level of cardiac troponin during the perioperative period was significantly decreased and the requirement for positive inotropic drugs during the perioperative period was significantly reduced ( P ＜ 0.05),and no significant change was found in the incidence of hyperalgesia or mortality of myocardial infarction during the perioperative period in remifentanil group ( P ＞ 0.05 ).Conclusion The efficacy of remifentanil combined anesthesia is better than that of fentanyl or sufentanil combined anesthesia in patients undergoing cardiac surgery.

OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy and repair of the injured posteromedial complex structure of the knee joint in the treatment of posterolateral knee dislocation with multiple ligament injuries.

METHODSFrom March 2008 to August 2012,22 patients (16 males and 6 females, ranging in age from 20 to 53 years old, with an average of 30.5 years old) with posterolateral dislocation of the knee were treated with primary reconstruction of ACL and PCL, combined with the repair of injuries in the posteromedial complex and soft-tissue. Eight patients had injuries caused by sports,5 patients road accidents and 9 patients falling down. The ACL was reconstructed using the gracilis and semitendinosus tendons. The PCL was reconstructed using LARS artificial ligaments (14 cases), or gracilis and semitendinosus tendons (8 cases). Suture repair was performed in 17 patients with posteromedial ligament injuries,and self-semitendinosus strengthening operations were performed in 5 patients. Continuouspassive montion (CPM) and active exercises were executed after operation at early stage. The IKDC and Lysholm system were used to evaluate therapeutic effects.

RESULTSAll the patients were regularly followed up, and the duration ranged from 11 to 56 months (averaged, 39 months). According to the IKDC scale,9 patients got a grade A result, 10 got a grade B result, and 3 got a grade C result. The IKDC subject score was 89.6±3.1 and the Lysholm scores was 90.7±1.8 at the latest follow-up, which were both better than those before operation.

CONCLUSIONReconstructing the ACL and PCL and repairing injured posteromedial complex of the knee followed by an active rehabilitation is an effective method to treat posterolateral knee dislocation.

Objective To evaluate the role of activator protein-1 (AP-1) in the up-regulation of heme oxygenase-1 (HO-1) expression during lipopolysaccharide (LPS)-induced acute lung injury (ALI) in rats.Methods Forty-eight healthy male Sprague-Dawley rats,weighing 200-220 g,aged 2.5-3.0 months,were randomly divided into 4 groups (n=12 each): normal control group (group C),ALI group,curcumin + ALI group (group Cur+ ALI),and curcumin group (group Cur).In groups C and ALI,normal saline 0.5 ml and LPS 10 mg/kg (0.5 ml) were injected intravenously,respectively,30 min after 0.1％ dimethyl sulfoxide (the vehicle for curcumin) 0.5 ml was injected intraperitoneally.In groups Cur+ ALl and Cur,curcumin 20 mg/kg (0.5 ml) was injected intraperitoneally,and 30 min later LPS 10 mg/kg and normal saline 0.5 ml were injected,respectively.The rats were then sacrificed at 6 h after injection of LPS.The lungs were removed for microscopic examination.The pathological changes of the lung were scored.The malondialdehyde (MDA) content,superoxide dismutase (SOD)activity and expression of HO-1,AP-1 and HO-1 mRNA in lung tissues were determined.Results Compared with group C,the pathological score and MDA content were significantly increased,the SOD activity was significantly decreased,and the expression of HO-1,AP-1 and HO-1 mRNA was up-regulated in groups ALl and Cur +AL(l) (P ＜ 0.05),and no significant change was found in the parameters mentioned above in group Cur (P ＞ 0.05).The pathological score and MDA content were significantly higher,and the SOD activity and expression of HO-1,AP-1 and HO-1 mRNA were significantly lower in group Cur + ALl than in group ALI(P ＜ 0.05).Conclusion Transcription factor AP-1 activation is involved in the up-regulation of HO-1 expression during LPS-induced ALI in rats.

Objective To investigate the awaken effect of naloxon on dexmedetomidine anesthetized mice and its mechanism. Methods Thirty Kunming mice of clean grade were randomly divided into 3 groups which included NAL group (Naloxon group), ATI group(Atipamezole group)and NS group (Normal Saline group). All groups were given dexme?detomidine 1 mg·kg-1 intraperitoneally. Naloxon 2 mg·kg-1, atipamezole 2 mg·kg-1 and normal saline 10 mL·kg-1 were ran?domly given intraperitoneally to the NAL, ATI and NS group respectively 90 minutes after dexmedetomidine administration. At timepoints prior to dexmedetomidine administration and 5, 15, 30, 60, 90, 95, 105, 120, 180 minutes after it, the sedative and analgesic effects besides recovery time (based on restore of righting reflex loss) were assessed. Results Sedation and analgesia effects became apparent within 5 minutes, and peaked at approximately 60 minutes then spontaneously recovered at 180 minutes after injection of dexmedetomidine. The sedative and analgesic effects were reduced in both ATI and NAL groups. Compared with ATI group, the sedation scores were higher at 95, 105 and 120 minutes after dexmedetomidine admin?istration than those in NAL group (P<0.05) but the scores were not statistically significant at 180 minutes between these two groups. Compared with NS group, the sedation scores were lower at time points of 95, 105, 120 and 180 minutes than those in NAL group (P>0.05). The analgesic scores were not statistically significant at time points of 95, 105, 120 and 180 min?utes between NAL group and ATI group, but they were lower in NAL group compared with NS group at timepoints of 95, 105 and 120 minutes (P>0.05). The recovery time in ATI and NAL group were shorter than that in NS group (F=1 793.368, P<0.05), but it showed no statistical difference between ATI group and NAL group (P>0.05). Conclusion Naloxone had a certain awaken effect on dexmedetomidine anesthetized mice.

Objective To investigate the role of apelin-13, a vasoactive peptide, in rat myocardial ischemia-reperfusion injury in vivo and explore its signal transduction pathway. Methods Rats were randomly divided into control group (n=10) and Apelin-13 group (n=15), and in vivo models of rat myocardial ischemia-reperfusion injury were established. Normal saline (control group) or Apelin-13 (Apelin-13 group) was administered intravenously 5 min before reperfusion. TTC and Evan's blue staining were used to determine the infarction size (IS) and area at risk (AAR), apoptotic cells were quantified by TUNEL method, and the expression of ERK1/2 was determined by Western blotting. Results IS/AAR and apoptosis index of Apelin-13 group were significantly lower than those in control group [(38.33±12.95) % vs (52.61±11.00)% and (0.21±0.02) vs (0.31±0.05)](P <0.05). The expression of p-ERK1/2 in Apelin-13 group was significantly increased than that in control group [(1.15±0.16) vs (0.63±0.07)](P < 0.05). Conclusion Apelin-13 may protect rat hearts from in vivo ischemia-reperfusion injury, reduce infarction size and attenuate myocardial apoptosis, which may be mediated by the activation of ERK1/2 MAPK signal transduction pathway.
