Chinese Journal of Orthopaedic Trauma 2014;16(7):591-598
Objective To compare the clinical efficacy of intramedullary pin versus plate fixation for displaced mid-shaft clavicle fractures.Methods The databases,PubMed,CENTAL and CBM,were searched according to the standards of the Cochrane Collaboration for all the randomized controlled trials (RCTs) and clinical controlled trials (CCTs) comparing intramedullary pin with plate fixation for treatment of displaced mid-shaft clavicle fractures.In addition,hand search was also conducted in relevant journals.Time limit for search was from the beginning till December 2013.Trial quality was assessed using the modified Jadad scale and effective data were pooled for Meta analysis with software RevMan5.2.7,including wound infection,hospital stay,wound size,intraoperative blood loss,operation duration,implant irritation,implant problems,delayed union,malunion,nonunion,total complications and Constant scoring.Results Three RCTs and 7 CCTs with 697 patients were included in our study.The modified Jadad scoring showed fine quality of the 10 trials.Intramedullary fixation was significantly superior to plate fixation in wound size,intraoperative blood loss,operation duration,hospital stay,wound infection,and symptomatic hardware (P < 0.05),but led to a significantly higher rate of implant problems (P < 0.05).However,no significant differences were identified in total complication rate,delayed union,nonunion,malunion or Constant score (P > 0.05).Conclusions The superiority of intramedullary fixation for displaced mid-shaft clavicle fracture lies in its advantages of minimally invasion,such as limited incision,less intraoperative bleeding,shorter operation time and hospital stay,less wound infection and implant irritation.Ahhough intramedullary fixation may lead to a higher rate of implant problems,it shows no significant differences from plate fixation in bone healing and functional recovery.

Background Increase of lens thickness at incipient cataract is a key factor of onset of primary angle-closure glaucoma (PACG).Phacoemulsification (Phaco) or phacotrabeculectomy (Phacotrabe) have been documented to be effective for the patients of PACG associated with cataract.However,which surgery is more effective and safe is lack of evidence.Objective This study was to assess and compare the clinical effectiveness of Phaco versus Phacotrabe for PACG with cataract.Methods The relevant literature was searched electronically from the PubMed (1966 to June 2011),EMB Reviews (1966 to June 2011) and Cochrane Library (Issue 1,2011).The manually searching of relevant conference proceedings was used as the supplement.The articles of randomized controlled trial (RCT) about the clinical effectiveness of Phaco versus Phacotrabe for PACG with cataract were included.The methodology quality of included literature was graded.The analysis indexes included intraocular pressure (IOP)-lowing range,postoperative administration of glaucoma drugs,incidence of positive complication,postoperative best corrective visual acuity (BCVA) and perimetry damage.The RevMan4.2 software from Cochrane Collaboration was used for the Meta analyses.Results Three RCTs about phaco versus Phacotrabe for PACG with cataract were selected in this study with the 164 eyes of 164 cases.Meta analysis showed that the IOP-lowing range was larger in the Phacotrabe group compared to only Phaco group with the WMD of 1.17 and 95% CI of 0.06-2.27 (P =0.040),and the drug dosage of anti-glaucoma was less in the Phacotrabe group in comparison with the Phaco group with the WMD of 0.5 and 95% CI of 0.24-0.77 (P =0.000).However,the incidence of postoperative complication was higher in the Phacotrabe group than that of the Phaco group with the RR of 0.08 and 95% CI of 0.02-0.33 (P =0.000).No significant difference was found in the BCVA (WMD =0,95% CI:-0.13-0.13,P=1.00) andperimetry (WMD =1.01,95%CI:0.56-1.82,P=0.98).Conclusions Compared with Phaco,Phacotrab has a better IOP-lowing effectiveness and slightly worse safety.Phaco and Phacotrab have a fairly influencc in the postoperative BCVA and perimetry.As the sample sizes of the included trials are relatively small,more welldesigned large-scale RCTs are needed.

Objective To observe the relationship of awake bispectral index (BISawake) and the postoperative cognitive dysfunction (POCD). Methods 100 patients aged 60~75 years with ASA status Ⅰ~Ⅱ, underwent elective lower abdominal surgery with intravenous anesthesia (propofol, remifentanyl and rocuronium). The BIS was adjusted in 40~60 during the surgery. Their cognitive function was assessed with the neuropsychological test battery commended by International study of postoperative cognitive dysfunction (ISPOCD). Results 8 patients withdrew for unwilling or serious complications. The BISawake was more than 65 in 68 patients (group A), and less than 65 in 24 patients (group B). The difference of the verbal learning immediate and delayed of Hopkins Verbal Learning Test-Revised was more in the group B than in the group A. Conclusion Lower BISawake may be associated with the decline of postoperative cognitive function.

OBJECTIVETo investigate the pathogenic factors of human cytomegalovirus (HCMV) infections.
METHODSTotally 36 serum samples were obtained from early pregnant woman and examined with ELISA for anti-HCMV antibody IgG and IgM. After artificial abortion,chorionic villus and decidua were also examined with polymerase chain reaction (PCR) for HCMV-DNA. When the results of PCR were positive, pathological changes of these chorionic villus and decidua were analyzed.
RESULTSThe results showed that only 10 samples were PCR positive while IgG and/or IgM antibody to HCMV was positive. After infection with HCMV, different changes occurred in chorionic villus and decidual trophoblastic cells placental villus were hyperplasic and decidua cells degenerated and necrotized followed by lymphocytes infiltration.
CONCLUSIONThese pathological changes may be one of pathogenic factors of HCMV.

OBJECTIVEThe present study was undertaken to design antisense oligodeoxynucleotides (AS-ODNs) of glial glutamate transporter-la (GLT-1a) and to evaluate the effectiveness of the designed AS-ODNs on the expression of GLT-1a.
METHODSFive sequences of GLT-1a AS-ODNs were designed according to the C terminus specific sequences of GLT-1a mRNA using antisense design software of IDT Com- pany. Western blot analysis was used to evaluate the inhibition effects of the five GLT-1a AS-ODNs on the expression of GLT-la.
RESULTSThe sequence of GLT-1a AS-ODNs with sequence of 5'-GGTTCTTCCTCAACACTGCA-3' could specifically inhibit the expression of GLT-1a in the hippocampal CA1 subfield of rats, while it had no effect on the expression of GLT-1b. This sequence showed similar inhibition on the expression of GLT-la in sham and ceftriaxone (Cef)-treated rats. It could also significantly inhibit the cerebral ischemic preconditioning (CIP)-induced up-regulation in the expression of GLT-1a. The magnitude of the inhibition in sham, Cef- or CIP-treated rats was similar by more than 60%.
CONCLUSIONFrom the designed five sequences of GLT-1a AS-ODNs, we obtained an effective sequence which can specifically inhibit the expression of GLT-1a.
