Objective:To evaluate the efficacy and safety of tirofiban,a platelet glycoproteinⅡb/Ⅲa Inhibitor,in percutaneous coronary intervention(PCI)of patients with acute non-ST segment elevation myocardial infarct(NSTEMI).Methods:A total of 114 patients with acute NSTEMI were enrolled in the trial from Sep.2005 to Jan.2007;they were randomly divided into 2 groups:tirofiban group(n=57)and placebo group(n=57).Patients in tirofiban group were given tirofiban for 24 h after PCI.All patients were routinely given heparin,aspirin and clopidogrel before CPI.The composite occurrence of death,myocardial infarction(MI),need for target vessel revascularization(TVR)after PCI,and the adverse effects(hemorrhage and thrombocypenia)were compared between the 2 groups.Results:One(1.8%)patient had angina pectoris and the other(1.8%)developed subacute thrombus in control group within 24 h after PCl;there was no such event in the tirofiban group.Two(3.6%)patients developed angina pectoris and 2(3.6%) developed subacute thrombus within 30 days after PCI in control group;one patient(1.8%)in birofiban group developed angina pectoris and one patient in birofiban group developed subacute thrombus.Each group had one case(1.8%)of upper digestive tract bleeding during hospitalization.No intracranial hemorrhage,skin/ mucosa hemorrhage,thrombocytopenia,or-death occurred in the 2 groups.Intravenous tirofiban treatment reduced the composite occurrence of death of NSTEMI patients after PCI(P
8.Reduction and screw fixation of condyle sagittal fracture.
Chinese Journal of Stomatology 2009;44(12):709-712
OBJECTIVETo investigate the technique and clinical effect in the surgical reduction and screw fixation of sagittal condylar fractures.
METHODSOpen treatment was performed on 21 cases (23 condyles) with sagittal condylar fractures. The condylar fracture segment was reduced and fixed by screw (long screw or lag screw). The patients began the mandible movement exercise early after the operation, and follow-up was performed in the first half year after the operation.
RESULTSFavorable results were obtained in all cases. Slight malocclusion was observed in 3 cases accompanied with mandible fracture, but normal occlusion was almost reestablished after one week of intermaxillary traction. The CT examination indicated the ideal condition of reduction and fixation of these condylar fractures. During the follow-up, the mouth opening was normal, and mandible movement and function was satisfactory.
CONCLUSIONSThe technique of reduction and screw fixation in condyle sagittal fracture can obtain stable reduction and fixation.

Objective To investigate the role of signal transduction of toll-like receptors(TLRs)in immunological pathogenesis in children with acute idiopathic thrombocytopenic purpura(ITP).Methods Thirty children with actue ITP and 30 age-matched healthy children were studied.Real-time fluorescent quantitative PCR was used to evaluate the levels of TLR 1-10 and signal transducing molecules,and cytokines associated with TLRs,such as IL-1?,granulocyte-macrophage colony-stimulating factor(GM-CSF),macrophage colony-stimulating factor(M-CSF)and IFN-?/? mRNA.Expressions of co-stimulatory molecules such as CD40,CD80 and CD86 in mo-nocyte/macrophage(MC)was analyzed by flow cytometry.Results Compared with healthy control group,the mRNA levels of TLR3,7,8 and 9 in ITP group were significantly up-regulated(Pa0.05).Transcription le-vels of MyD88-dependent and-independent pathway molecules such as MD-2,MyD88,IRAK-4,TRAF6,TAK1,TRIF,TRAM,TBK-1 and IFN-? were significantly up-regulated in acute ITP(Pa0.05).Conclusion Aberrant activation of toll-like receptors signaling may be one of the initiating factors of immune dysfunction in children with acute ITP.

Objective To investigate the features of chronic prostatitis during puberty(CPP)and the effects of pelvic floor biofeedback therapy.Methods Totally,25 CPP children (mean age,16 years) and 15 children (mean age,16 years) with normal lower urinary tract as controls were included.In CPP group,NIH-CPSI scores were evaluated,expressed prostatic secretions (EPS) were examined,and bacterial culture was done;and CPP patients were categorized based on the definitions of NIH types.In both groups, urodynamic examination was performed,including evaluation of uroflow curve,maximum flow rate (Q_(max)), post-voiding residual urine (PVR),detrusor-sphincter dyssynergia (DSD),maximum detrusor pressure (P_(det,max))and maximum urethral closure pressure (MUCP).CPP patients underwent biofeedback therapy, and 10 weeks later the effects were assessed.Results In CPP group,NIH typing showedⅡ,ⅢA andⅢB in 1,3 and 21 cases,respectively.Before treatment in CPP and control groups,the incidence of staccato voiding (20 cases vs 1 case),DSD (22 cases vs 1 case),Q_(max)(10.7?3.7 vs 15.0?4.3ml/s),PVR (7.7?4.1vs 3.2?2.6ml),P_(det,max)(115.1?33.6vs 76.8?16.6cm H_2O)and MUCP(176.5?45.7 vs 86.2?28.5cm H_2O)all showed significant differences between the 2 groups(P<0.05).In CPP group,the differences in pain(4.6?2.2 vs 2.1?1.6),urination (7.9?2.0vs 2.2?1.7),life impact (9.4?2.2vs 2.6?2.1)and total scores(22.0?5.2vs 7.0?4.2) of NIH-CPSI and Q_(max)(10.7?3.7 vs 14.9?5.6) between pre-and post-biofeedback were significant (P<0.05).Conclusions The main type of CPP is categoryⅢB.The primary symptom is voiding disorder,which leads to greater psychological stress in patients.Children with CPP have pelvic floor dysfunctions and multiple abnormal urodynamic param- eters.The short-term effect of biofeedback strategies for CPP is satisfactory.
