Objective To characterize the growth curve of Brucella in Bact/Alert blood culture system which may be helpful to predict the growth of Brucella strain for earlier clinical diagnosis of brucellosis.Methods The epidemiological,clinical and labo-ratory data including growth curve of Brucella were reviewed and analyzed retrospectively for 15 cases of brucellosis as con-firmed by positive serological test and brucellosis agglutination test.Results All the 15 patients had irregular fever and history of animal exposure,even though their clinical feature and signs varied greatly.The growth curve of Brucella in blood culture showed the same chracteristics in the 15 patients,including:the time to positive alarm was about 72 hours,a longer lag phase, shorter logarithmic phase,a shorter vertical axis corresponding to the logarithmic phase,and a flat stable phase.Conclusions The clinical manifestation of brucellosis is variable and non-specific.Lack of awareness of this disease makes the clinicians mis-diagnose it easily.Therefore,blood culture is critical for clarifying the etiology in febrile patients.The growth curve of bacteria during blood culture is useful for early diagnosis of brucellosis and prevention of laboratory infections.

Objective To evaluate the efficacy of parecoxib sodium for preemptive analgesia.Methods PubMed,EMBASE,Cochrane Library,and CNKI database were searched for randomized placebo-controlled trials involving the efficacy of parecoxib sodium for preemptive analgesia.The modified Jadad scale was used for quality assessment.Evaluation indexes included VAS scores at 1,6,12 and 24 h after operation,consumption of morphine within 24 h after operation,and incidences of nausea and vomiting after operation.Meta-analysis was conducted using the Cochrane Collaboration's RevMan 5.0.2 software.Results Fourteen randomized placebo-controlled trials involving 1086 patients were included in our meta-analysis.The modified Jadad scale scores for the 14 studies were ≥ 4.The patients were divided into 2 groups:placebo group and parecoxib sodium 40 mg injected before operation group.The results of meta-analysis showed that VAS scores at 1,6,12 and 24 h after operation were significantly decreased,the consumption of morphine within 24 h after operation was reduced,and the incidences of nausea and vomiting after operation were decreased in parecoxib sodium 40 mg injected before operation group as compared with placebo group (P ＜ 0.05).Conclusion Intravenous injection of parecoxib sodium 40 mg before operation can produce significant preemptive analgesic efficacy and is helpful in decreasing the adverse effect of postoperative analgesia.

Objective To explore the relationship between administration of different doses of colloid before general anesthesia induction and general anesthesia-induced hypotension. Methods Fifty patients for selective gastrointestinal operations were randomly divided into 5 groups according to the volume of colloid administered 30 min before general anesthesia induction: 0 mL/kg group (control group), 4 mL/kg group, 8 mL/kg group, 12 mL/kg group and 15 mL/kg group. To replace the deficit of hypovolemia before operation, crystalloid was given to each patient. Anesthesia was induced with propofol 25 min after infusion. Hemodynamic parameters were compared before and after anesthesia induction among groups. Results The changes in diastolic blood pressure and mean arterial blood pressure were related to colloid supplementation volume (r=-0.657, P<0.01). There were significant differences between control group and 8 mL/kg group, 12 mL/kg group and 15 mL/kg group (P<0.05), while there was no significant difference among 8 mL/kg group, 12 mL/kg group and 15 mL/kg group. Conclusion Administration of colloid before general anesthesia induction attenuates the severity of general anesthesia-induced hypotension, especially when the dose of colloid is over 8 mL/kg.

Objective To summarize the clincal effect of open reduction and internal fixation with locking-proximal-humerus-plate(LPHP)to treat proximal humeral fractures.Methods A total of 19 eases with proximal humeral fractures were treated with LPHP from August 2003 to February 2006 in this study.Their mean age was 58.6 years old.According to Neer classification,two cases were with two- part fractures,nine with three-part fractures and eight with four-part fractures including seven cases with osteoporosis.Redaction and fixation was done via deltopeetoral-groove approach.Bone graft was applied for five eases.Results The follow-up period was 3 to 32 months(mean 17 months).All cases were healed and the union period of 3-5 months.According to the Near shoulder score,the results showed that ten cases were excellent,6 cases good,with excellent rate of 84%.Conclusion The LPHP method is suitable for osteoporosis and comminuted proximal humeral fractures and enhances the treatment effect.

OBJECTIVE To investigate the clinical distribution and drug resistance status of Stenotrophomonas maltophilia and provide clinical guidance for treatment.METHODS Sixty clinical isolates of S.maltophilia were identified with GNI+ cards of VITEK-32.Drug sensitivitiy were detected by Kirby-Bauer disc diffusion method.The data were analyzed by WHONET5.3 software.RESULTS Thirty-eight strains were isolated from sputum(63.3%).Infection caused by S.maltophilia mainly occurred at the departments of respiratory diseases,ICU,old cadre,et al.Sixty isolates of S.maltophilia were highly resistant to imipenem,aminoglycosides and most of ?-lactam antibiotic,but showed the lowest resistance rate(16.7%) to SMZ/TMP.Then resistance rate of S.maltophilia to minocycline,levofloxacin,cefoperazone/sulbactam,piperacillin/tazobactam,and ticarcillin/clavulanic acid was 18.3%,20.0%,21.7%,25.0% and 30.0%,respectively.CONCLUSIONS The drug resistance of S.maltophilia is extremely severe.Among different areas of china the drug resistance is obviously different.Treatment based on drug susceptibility test should be adapted as soon as possible.

This article aimed to study the antigenicity of nucleocapsid proteins (NPs) in six pathogenic phleboviruses and to provide theoretical evidence for the development of serological diagnostic reagents. NPs of six pathogenic phleboviruses were expressed and purified using a prokaryotic expression system and rabbits were immunized with individual recombinant NPs. Cross-reactions among NPs and rabbit sera were determined by both indirect ELISA and Western blotting analyses, and the sera titer was determined by indirect ELISA. Furthermore, sera from SFTS patients were also detected by each recombinant NP as a coating antigen using indirect ELISA. The cross-reactions and the sera titer were subsequently determined. Both the concentration and purity of recombinant NPs of six pathogenic phleboviruses met the standards for immunization and detection. The results of indirect ELISA and Western blotting showed that each anti-phlebovirus NP rabbit immune serum had potential serological cross-reactivity with the other five virus NP antigens. Furthermore, the sera from SFTS patients also had cross-reactivity with the other five NP antigens to a certain extent. Our preliminary study evaluated the antigenicity and immune reactivity of six pathogenic phleboviruses NPs and laid the foundation for the development of diagnostic reagents.

Two recombinant plasmids pVAX/Sj23 and pVAX/mIL-18 containing Schistosoma japonicum 23 000 membrane protein (Sj23) and murine IL-18 were evaluated for their ability to induce immune responses and to protect against S. japonicum challenge in mice. All animals vaccinated with pVAX/Sj23 alone or plus pVAX/mIL-18 developed specific anti-SWAP (soluble worm antigen preparation) ELISA antibody and splenocyte proliferation response,and co-injection of pVAX/mIL-18 significantly increased the production of IFN-γ and IL-2 compared with pVAX/Sj23 alone, indicating that IL-18 enhances the Th1-dominant immune response. The challenge experiment showed that worm reduction rates in pVAX/Sj23 group compared with control group (pVAX1) was 26.5% and in the pVAX/Sj23 plus pVAX/mIL-18 group was 41.9% ,and the hepatic egg reduction rates were 42.7 and 49.6%,respectively. These results indicated that co-injection of an IL-18 plasmid with Sj23 DNA vaccine efficiently improves the protective effect against S. japonicum infection.
