Objective To evaluate the accuracy of the soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) and lipopolysaccharide binding protein (LBP) as diagnostic indices for neonatal serious bacterial infections (SBI). Methods A total of 171 newborns were enrolled in the study, and were classiifed into SBI group (including early-onset and late-onset), non-SBI group according to clinical manifestations, laboratory examinations and the time of disease onset. Serum sTREM-1, LBP and C-reactive protein (CRP) levels were measured. Receiver operator characteristic curve (ROC) was drawn, and the area under curve (AUC) was calculated. Each index was evaluated for the diagnostic value of neonatal SBI. Results The sTREM-1 and LBP levels were signiifcantly higher in SBI group than those in non-SBI group (P=0.000). The AUC of ROC for sTREM-1, LBP and CRP in early-onset SBI was 0.888, 0.839 and 0.706, respectively. The AUC of ROC for sTREM-1, LBP and CRP in late-onset SBI was 0.860, 0.865 and 0.705, respectively. Conclusions Both sTREM-1 and LBP are useful for the diag-nosis of neonatal SBI.

BACKGROUND: Fiber posts are currently perceived as promising alternatives to cast metal posts, as their elastic modulus are similar to that of dentin, producing a favorable stress distribution and providing more esthetic outcomes for endodontically treated teeth. Failure of a fiber post and composite resin core often occurs at the junction between the two materials. This failure process requires better characterization.OBJECTIVE: To compare the bond strength of fiber posts after three surface treatments to a composite resin. METHODS: The coronal portions of 20 mandibular premolars with a single root canal were removed and were endodontically treated. After post space preparation, the roots were divided into four groups and the fiber posts and resin cores were lured. In the three testing groups, the surfaces of fiber posts were silaned, sandblasted or etched with hydrogen peroxide. In the control group, the surfaces of fiber posts were not treated. All specimens were exposed to cyclic loadings and thermal cycles. The roots were sectioned into slices with 1 mm thickness and their bond strengths were tested with a universal material testing machine. Test piece following testing was placed under optical microscope to observe the breakage method.RESULTS AND CONCLUSION: Stickiness strength was significantly greater in the sandblasted and hydrogen peroxide groups compared with the control group (P < 0.05). No significant difference in stickiness strength was determined between the sandblasted and hydrogen peroxide groups (P > 0.05). No significant difference in stickiness strength was detected between the silaned and control groups (P > 0.05). The splicing destruction among each group was the main breakage method between materials and fiber posts. The surface treatment of fiber posts with sandblast or hydrogen peroxide significantly enhanced the bond strength of the composite resin tested. The surface treatment of fiber posts with silane did not enhance the bond strength of the composite resin.

Objective To evaluate the blood-saving effect of tranexamic acid in elderly patients undergoing total hip replacement.Methods One hundred and sixty ASA Ⅱ or Ⅲ patientss of both sexes,aged 65-70 yr,with a body mass index of 16-22kg/m2,undergoing total hip replacement,were randomly divided into 2 groups(n =80,each):control group(group C)and tranexamic acid group(group T).Anesthesia was induced with midazolam,fentanyl,etomidate and atracurium.The patients were tracheal intubated and mechanically ventilated.PEr CO2 was maintained at 35-45 mm Hg.Aneslhesia was maintained with propofol,remifentanil and atracurium.Before the skin incision,tranexamic acid 15 mg/kg was infused over 15 m in in group T,while the equal volume of normal saline was given instead in group C.Hemoglobin(Hb),platelet count(PLT),prothrombin time(PT),and activated partial thromboplastin time(APTT)were monitored during operation to guide blood transfusion.Intraoperative and postoperative blood loss and allogeneic blood transfusion were recorded.Postoperative complications were also recorded.Results There was no significant difference in the amount of intraoperative blood loss between the two groups(P ＞ 0.05).The amount of postoperative blood loss was significantly smaller and less allogeneic red blood cell was transfused in group T than in group C(P ＜ 0.05).No complications occurred after operation in either group.Conchusion Tranexamic acid has blood-saving effect in elderly patients undergoing total hip replacement,but the clinical value is limited.

OBJECTIVETo observe the effect of catgut implantation at acupoint on the content of tumor necrosis factor alpha (TNF-alpha), and to explore its mechanism for treatment of ankylosing spondylitis (AS).

METHODSSeventy-four AS patients were randomly assigned to the observation group and the control group by digit random table, 37 in each group. Patients in the control group took Sulfasalazine Enteric-coated Tablet (SECT), 0.5 g each time, three times daily for 3 months. Those in the observation group additionally received catgut implantation at acupoint for 3 months. Changes of visual analogue scale (VAS), Schober test, pillow wall distance, thoracic activity, erythrocyte sedimentation rate (ESR), C reactive protein (CRP), and TNF-alpha were compared after 3 months of treatment.

RESULTSThere was obvious change in VAS, Schober test, pillow wall distance, thoracic activity, ESR, CRP, and TNF-alpha after treatment in the both groups, showing statistical difference when compared with before treatment (P < 0.05, P < 0.01). The aforesaid indices were obviously improved after treatment in the observation group (P < 0.05, P < 0.01).

CONCLUSIONCatgut implantation at acupoint, as an assistant therapy, could significantly improve clinical symptoms and signs, decrease the level of TNF-alpha, and its effect was superior to that of oral SECT administration alone.
