OBJECTIVE:To systematically review the effectiveness and safety of liraglutide in the body mass loss of patients with overweight and obesity,and provide evidence-based reference for clinical treatment. METHODS:Retrieved from Medline, EMBase,CJFD,Wanfang and VIP,randomized controlled trials(RCT)about liraglutide versus placebo in the treatment of over-weight and obesity were collected. Meta-analysis was performed by using Rev Man 5.1.0 software after data extract. RESULTS:To-tally 8 RCTs were enrolled,involving 3 560 patients. Results of Meta-analysis showed weight loss degree [MD=-1.71,95%Cl (-2.25,-1.17),P<0.001] and the percentage of proportion loss more than 5% to total patients [RR=2.20,95%CI(1.83,2.63), P<0.001] in liraglutide group were significnatly more than blank control group;while the incidences of nausea,vomiting,diar-rhea,mild-to-moderate hypoglycemia and peripheral edema were significantly higher than control group. CONCLUSIONS:Liraglu-tide is effective for overweight and obesity patients. And there is mild adverse reactions but high incidence of gastrointestinal ad-verse reactions,which should be vigilant.

OBJECTIVE:To evaluate the curative efficacy of granulocyte macrophage colony stimulating factor (GM-CSF) as an adjunctive therapy for the treatment of acute myeloid leukemia (AML). METHODS: Randomized controlled trials (RCTs) of GM-CSF in the treatment of AML were retrieved from PubMed,EMBase,Cochrane Library,CBMdisc and CNKI database by computer as well as from the leukemia-related journals manually for a quality evaluation of the methodology and Meta analysis using RevMan5.0 software. RESULTS: A total of 10 RCTs were included,of which,3 RCTs were graded as A,5 as B and 2 as C. The results demonstrated that there were no significant differences of indexes among groups as complete remission (CR) rate,relapse rate,infection rate and length of hospital stay,etc. CONCLUSION: The available clinical research results showed that GM-CSF adjunctive therapy could neither increase CR rate,nor decrease the relapse rate,infection rate or length of hospital stay.

OBJECTIVE:To systematically review the difference of phlebitis induced by Alprostadil injection with different ad-ministration routes,and to provide evidence-based reference for clinical rational use. METHODS:Retrieved from PubMed,EM-Base,Cochrane Library,CBM,CJFD,VIP and Wanfang database,RCTs about phlebitis induced by Alprostadil injection with dif-ferent administration routes were collected. Meta-analysis was conducted by Rev Man 5.2 statistical software after literature screen-ing,data extraction and quality evaluation according to Cochrane System Evaluator's Manual 5.1.0. RESULTS:A total of 20 RCTs were included,involving 2562 patients. The results of Meta-analysis showed that the incidence of phlebitis induced by intravenous injection was significantly higher than that induced by intravenous dripping [OR=4.11,95%CI(1.59,10.67),P=0.004] and intrave-nous pump [OR=3.50,95%CI(1.50,8.16),P=0.004]. The incidence of phlebitis induced by general apparatus infusion was signifi-cantly higher than that induced by fine filtering infusion [OR=0.03,95%CI(0.01,0.08),P<0.001],with statistical significance. CONCLUSIONS:The incidence of phlebitis induced by low-concentration of Alprostadil injection or fine filtering infusion is low-er,and that of intravenous injection is higher.

The paper is to report the development of an optic-fiber sensing technology method to analyze metronidazole tablets rapidly. In this fiber-optic sensing system, the light from source delivering to probe can be dipped into simple-handling sample solution, absorbed by the solution and reflected to the fiber-optic and detected in the detection system at last. Then the drug content can be shown in the screen from the ultraviolet absorption spectra and the consistency between that obtained by this method and that in China Pharmacopoeia can be compared. With regard to data processing, a new method is explored to identify the authenticity of drugs using the similarity between the sample map and the standard pattern by full ultraviolet spectrum. The results indicate that ultraviolet spectra of tablets can be obtained from this technology and the determination results showed no significant difference as compared with the method in China Pharmacopoeia (P > 0.05), and the similarity can be a parameter to identify the authenticity of drugs.

Objective To investigate the value of endovascular surgery for the treatment of thromboangitis obliterans (TAO). Methods Sixteen patients (18 limbs) with thromboangitis obliterans were treated by percutaneous transluminal plasty (PTA). Results Angiographic success on the limb basis was achieved in 15 of 18 treated limbs and the initial technical success rate was 83.34%. Doppler anklebrachial index (ABI) increased from 0.33±0.16 to 0.79±0.23 one week after PTA. The follow-up time was 2～24 months, the average time was 10.84 months. The 3-month, 12-month accumulated primary patency rate were 81.33% and 60. 23% respectively. Conclusion PTA is effective primary invasive treatment for thromboangitis obliterans yielding acceptable primary clinical success with a low complication rate and resulting in moderate long-term clinical patency and a high limb salvage rate.

Objective To evaluate the surgical techniques and clinical applications of single-port transumlilical laparoscopic dismembered pyeloplasty for the treatment of ureteropelvic junction obstruction (UPJO). Methods From August 2009 to March 2010, 15 patients were treated with single-port transumbilical laparoscopic dismembered pyeloplasty. There were 12 males and 3 females,aged 12 to 55 years with an average age of 20 years, who were diagnosed by diuretic renography,IVU, and MRU et al. A single umbilical incision of 3. 5cm was made for single-port trocar and a flexible-tip 0°digital video-laparoscope was used in all cases. The procedures were performed according to the methods used in classical laparoscopic dismembered pyeloplasty with general instruments. ResultsAll operations were performed successfully without conversion to open surgery. The mean operative time was 90 (75-145) min, and the mean hospital stay length was 6 days. No organs injury occurred during operation, and no urine leakage was found afer operation. The symptoms of low back pain disappeared and hydronephrosis reduced apparently or dispeared without any anastomotic stenosis after follow-up of 4-6 months. Conclusions Single-port transumbilical laparoscopic dismembered pyeloplasty is feasible, effective and safe for the treatment of UPJO.

Objective To investigate the clinical value of cardiac troponin Ⅰ(cTnⅠ) and creatinine kinase MB(CK-MB) in early diagnosis of myocardial injury(MCI) in neonatal asphyxia.Methods The serum cTnⅠ and CK-MB in neonates [34 with asphyxia and MCI,38 with asphyxia but no MCI(NMCI)],and 30 cases of normal control(NC) were measured with direct immunoassay chemiluminometric technology and immunoinhibition enzymes-activated assay.Results The cTnⅠ level in NC group had no changes within 10 days after birth,MCI group were significantly higher than those in NMCI and NC groups(all P0.05).The diagnostic sensitivity,specificity and accuracy of cTnⅠ for neonates with MCI were 91%,88% and 89%,respectively;and of CK-MB were 85%,68% and 74%,respectively.Conclusions cTnⅠ and CK-MB can be taken as early diagnostic markers of MCI in neonates with asphyxia,(cTnⅠ) is better than CK-MB.

OBJECTIVEThe purposes of this study was to investigate the effects of luting agents on the resultant color of IPS e.max all-ceramic veneer restorations, and to evaluate the similarity of try-in pastes and the corresponding luting agents on the final color.

METHODSDisc-shaped ceramic specimens were fabricated and seated on four shades of resin specimens to mimic the complex of ceramic veneer laying on tooth substrates. Try-in pastes and luting agents (Shades of TR, B0.5, A1, A3, W0) were applied into the inter-layer of ceramic and resin specimens, respectively. The color of the combinations was measured using a spectrophotometer and subsequently converted to CIE L*a*b* values. Color changes after luting agent applied, and between try-in paste and corresponding luting agent were calculated and registered as DeltaEresin and DeltaEpaste-resin.

RESULTSDeltaEresin value of A2, A3 backgrounds was more than 1.0. DeltaEresin value of A4, A5 backgrounds was less than 1.0. The DeltaEpaste-resin value of A3 backgrounds was more than 1.0, whereas, A2 was less than 1.0 (except for shade W0). The DeltaEpaste-resin value of shade W0 was significantly different from other shades of luting agents.

CONCLUSIONThe color of ceramic veneer restorations were affected by luting agents with A2, and A3 background colors. The agreement of the try-in paste and the corresponding luting agent was excellent for A2 background (except for W0).
