OBJECTIVE To find out fulminate epidemiological features of Stenotrophomonas maltophilia in ICU and the ways to prevent and treat this nosocomial infection.METHODS The case histories from 4 inpatients who developed S.maltophilia infection in the same ward from Feb 5 to 16,2006,were studied retrospectively to find out the reasons of its onset and its treatment based on the sputum culture results.RESULTS The fulminate S.maltophilia was found from the rail of the patient bed,the connection part of water container of 2 respiratory machines of exhalation valve assembly and the liquid of ultrasonic aeriation machine.CONCLUSIONS The infection is a localized one.The main reasons of the infection are unthorough disinfection of respiratory machine and the contamination of medical treatment environment.Whenever the infection is found in the ward,the thorough disinfection needs immediately,and no new patient admitted.

Eleven patients underwent acetabulum revision using modified anterolateral approach due to acetabulum loosening but femoral prosthesis in sound fixation following total hip arthroplasty in Department of Joint Surgery,Tianjin Hospital between August 2002 and February 2005. During the mean follow-up of 4.2 years,all 11 patients gained primary stable fixation and good function. One patient underwent another revision due to infection; one developed femoral prosthesis loosening and underwent femoral revision. X-ray of the other patients showed no loosening or dislocation or radiotransparent region surrounding the prosthesis. One patient developed lateral femoral cutaneous nerve injury and relieved 6 months later.

From February 2002 to May 2007,9 cases(9 hips) of periprosthetic fractures during the primary total hip arthroplasty for developmental dysplasia of the hip were selected,including 1 male and 8 females aged 52-69 years.In the primary total hip arthroplasty,femoral prosthesis with the same size as intramedullary reamer and acetabular prosthesis with 2 mm diameter larger than acetabular reamer were used.The pain,function,range of motion and degree of deformity were accessed using the Harris score.The patients were followed for 1-6 years.Among the 9 patients with periprosthetic fractures,4 acetabular fractures were stable which were treated by additional augmentation screws,and 1 fracture was unstable which was treated by structural bone grafting and additional screws.And there was one Vancouver type AG fracture which was treated by cerclage wire,3 Vancouver B1 fractures which were fixed by locking compression plate(LCP) or cerclage wire,and one Vancouver type C fracture which was also fixed by LCP.No component loosening or migration was found in the postoperative X-ray.The mean Harris score was 87.2 at the final follow-up.The results of the study show that during the primary total hip arthroplasty in patients with developmental dysplasia of the hip,the oversize of the acetabular component should be controlled to equal to or less than 2 mm.For patients with severe osteoporosis,acetabular components with the same size to reamer are recommended combined with additional screws,or cemented cup.When an acetebular fracture is found during total hip arthroplasty,we could use additional screws or bone grafting.Once a periprosthetic femoral fracture occurs during the operation,methods of fixation should be selected based on the type of the fracture and stability of the prosthesis.

The prevalence of diabetic macular edema ( DME ) was 3.56％ in type 2 diabetics and i 0. 8％ in patients with DR. Diabetes duration and proteinuria were the common risk factors of DR and DME.

ObjectiveTo observe the change of cardiac function after acute myocardial infarction (AMI) in rabbit model,and to study MRI characteristics of left ventricular remodeling (LVR).Methods Forty-five japanese white rabbits underwent chest-opening coronary artery ligation surgery to obtain rabbit myocardial infarction model The animals were scanned on a 1.5 T MR scanner ( GE Healthcare,Chalfont St.Giles,UK) at six time-points as surgery,1,2,4,6,8 weeks after surgery. Cardiac function parameters were measured,including left ventricular end diastolic volume ( EDV ),stroke volume ( SV ),ejection fraction (EF),peak ejection rate ( PER ) and peak firing rate (PFR).At each time point,5 rabbits were randomly selected and performed re-thoracotomy to obtain heart specimen.Each specimen was examined by MRI with the diffusion tensor imaging ( DTI ).The value of ADC and fractional anisotropy (FA) were collected. Cardiac function data sets of different time points were analyzed using repeated measures data of ANOVA.The FA and ADC values of infarction myocardium set of different time points or different parts of the myocardium were analyzed using one-way ANOVA. The average was compared statistically between two adjacent groups using LSD-t test. Results Left ventricular EDV increased in progress with the time.It was increased from ( 2.21 ± 0.35 ) ml preoperatively to ( 3.15 ± 0.57 ) ml 8-week postoperatively.But the difference was not statistical significant ( F =1.384,P =0.220).EF was decreased from(57.31 ± 11.11 )％ to( 34.71 ± 8.72 )％.It dropped significantly and the difference was statistically significant (F =27.134,P =0.001 ).EF showed a downward trend with the increase of EDV.By linear regression analysis,an equation was set up with y =- 5.58x + 57.7 ( F =8.855,P =0.005 ).On the other hand,PER showed a progressive decline from (27.31 ± 13.06) ml/s to ( 17.31 ± 6.41 ) ml/s ( F =2.105,P =0.037 ),and PFR decreased from ( 23.79 ± 14.15 ) ml/s to ( 12.07 ± 6.91 ) ml/s ( F =2.366,P =0.011 ).FA value decreased from 0.442 ±0.093 to 0.107 ±0.037( F =12.61,P =0.001 ),and ADC valueshowed upward trend from (5.07 ± 1.15) ×10-4 mm2/s to(6.39 ±0.78) ×10-4 mm2/s (F=4.166,P =0.022 ).FA values of infarct,adjacent and remote region were 0.201 ± 0.049,0.316 ± 0.127 and 0.323 ± 0.117 respectively( F =3.896,P =0.004 ),and the ADC values in these regions were (6.19 ± 1.78 ) ×10 -4,(5.44 ± 2.63 ) × 1 0 -4,(5.29 ± 2.02 ) × 10 -4 mm2/s respectively ( F =3.248,P =0.018 ).FA and ADC values were significantly different between the infarct region and adjacent region ( t =7.327,P =0.001 ;t =3.292,P =0.005,respectively),but there was no significantly different between adjacent region and remote region ( t =1.024,P =0.129 ; t =1.467,P =0.164,respectively ).ConclusionsMRI measurement of parameters of cardiac function can be used to monitor the process of left ventricular function remodeling after AMI.The process of micro-structural remodeling of myocardium can be reflected by DTI.MRI provides a feasible imaging modality for LVR after AMI.

Objective To construct bispecific antibody BsAb1/17 against both IL-1β and IL-17A,express and purify the biologically active BsAbl/17 protein in prokaryotic system for further studies and applications. Methods VH1VL17-CL and VL1VH17-CH1 gene segments were constructed by overlap-PCR.Restriction enzyme sites Nco Ⅰ and BamH Ⅰ were designed at the 5'and 3' end primers respectively. The products of overlap-PCR were ligated to the Nco Ⅰ/BamH Ⅰ -prepared pET-27b vector. The recombinant plasmids pET-27b-VH1 VL17-CL(petA) and pET-27b-VL1 VH17-CH1 ( petB ) were transformed into E. coliRosetta separately. The expressing products were analyzed by SDS-PAGE and Western blot. Neutralization activity of the bispecific antibody for blocking the induction of IL-18 expression by IL-1β in human T cells was determined by real-time PCR. Neutralization activity of the bispecific antibody for blocking the induction of IL-6 expression by IL-17A in HeLa cells was determined by ELISA assay. Results The structure of the plasmids pET-27b-VH1 VL17-CL(petA) and pET-27b-VL1 VH17-CH1 (petB)was confirmed by DNA sequencing. After induction, the fusion proteins were expressed mainly as inclusion bodies. The purity of the both proteins exceeded 90%. SDS-PAGE analysis suggests the relative molecular mass of both products expressed by petA and petB were approximately 38× 103, which is in accordance with the theoretical value. The results of Western blot and ELISA test demonstrated that BsAb1/17 molecule had binding ability to both IL-1β and IL-17A. The BsAb1/17 could block IL-1β to stimulate human T cell to express IL-18 and block IL-17A to stimulate HeLa cell to express IL-6. Conclusion We successfully constructed a novel bispecific antibody BsAb1/17 against both IL-1 β and IL-17A, and expressed biologically active BsAb1/17 protein in prokaryotic system.
