Objective To study the clinical outcomes of titanium-coated interbody fusion system in treating lumbar isthmic spondylolisthesis.Methods A retrospective study was made in 22 cases with lumbar isthmic spondylolisthesis including 15 with degree I spondylolisthesis and seven with degree II spondylolisthesis treated by posterior lumbar interbody fusion using titanium-coated fusion cages from June 2002 to December 2003 in our hospital.There were six males and 16 females,with age range of 41-68 years(mean 52.5 years).In all cases,double cages were implanted with additional posterolateral bone graft,supplemented with pedicle screw systems.The average preoperative and postoperative disc space height,foraminal height,segmental and lumbar lordosis,spondylolisthesis and domain of sagittal rotation on flexion-extension radiographs were measured and fusion state observed.The Oswestry disability index (ODI)was used to evaluate the clinical outcome.Results The fusion rate was 95.4%.There was significant recovery of disc space height,foraminal height and domain of sagittal rotation.ODI decreased significantly.Conclusion The anatomic titanium-coated fusion system is effective and safe in treatment of lumbar isthmic spondylolisthesis because it has advantages in restoring sagittal alignment and keeping bony endplate intact.

0.37).Meanwhile a good correlation (Y=0.99X-0.18,r=0.987) was obtained. Though Westergren method correlated preferably with MICROTEST 1 (Y=0.86X+1.27,r=0.906),there was a markedly different (t=3.174,P=0.001).At last different references values were collected, according to sex and age.Male,32.5 mm/1 h(60 years old);Female, 34.03 mm/1 h(50 years old).Conclusions MICROTEST 1 correlated preferably with Westergren method.The examination by MICROTEST 1 needs small quantity of sample and fewer time.Furthermore,it has good repeatability and stability.The factors such as temperature and Hct have little influence on the results.The result suggested that it is suitable to apply MICROTEST 1 to large- scale clinical laboratory or other labs.But the reference value of ESR was influenced by age,which should be considered in clinical usage.

Objective To discuss the strategy and intervention measures of the iodine deficiency disorders (IDD)control in coastal salt.producing areas so as to shoot the problem of non-iodized salt causing IDD.Methods Accordinng to different areas,periods and crowds,eomplicatd measures and strategies were taken such as supply of iodized salt to peopie in special need while universalizaion of iodized salt,health promotion,private salt factory censu8 and close.iodized salt quality monitoring and promotion of technology of iodized salt producion in Xiamen, where the probiem of non-iodized salt Was serious since 1995.Results Iodized salt manufactured Was qualified in a increased rate from 89.50% in 1995 to 96.17% in 1997,stablized at 99.00%since 2000.Qualified iodized salt sold in the shops waft increased from 87.33%in 1996 to 96.33%in 1998.Popularization covered by iodized salt in urban areas increaased from 0.92%in 1 995 to 100.00%in 2000,and it Was increased from 0 to 99.00%in suburban area8 and increased from 0 to 89.00%in rural areas.Since 2001 iodized salt covered up 93.00%of the people.The rate of child goitre in urban,suburban and rural areas respectively Wag 16.44%(228/1387), 20.57%(266/1293) and 24.93%(651/2611).Moreover,beginning from 1996,it reduced tO below of 5.00%respectively in 1999,2001 and 2005.The median of urinary iodine of children in urban,suburban and rural areas respectively was 137.50, 102.12,94.66 μg/L in 1995,since 1997 it reached 100.00μg/L and kept at 120.00μg/L In 2007 the median of urinarv iedine of children respectively was 271.10,240.40,198.10μg/L in urban,suburban and rural areas.The pereentage of awareness of IDD knowledge was 74.00%(444/600)in students in 1997 and reached 95.00% since 2000.Conclusion The paRern of eliminating iodine deficiency dis ease in Xiamen has successful established,which works efficiently and sets an example for iodized salt supplement in non-iodized salt areas and continually eliminating the iodine deficiency disease.

AIM:To study the feasibility of recombinant adeno-associated virus(rAAV)as a vector to transfer the green fluorescent protein(GFP)gene as a target gene into rabbit retina.METHODS:Intravitreal injection of rAAV-gfp was performed in either eye for each rabbit with the other eye taken as control.At the 3rd,7th,and 14th day after injection,the eyeballs were removed,and the retinas were flat-mounted on glass slides to inspect the retinal fluorescence,respectively.RESULTS:After intravitreal injection of rAAV-gfp,the presence of fluorescent spots in the cytoplasm of retinal cells indicated that GFP gene was efficiently transferred and expressed in the rabbit retina.CONCLUSION:Recombinant adeno-associated virus is a reliable and simple vector for transferring target gene,e.g.,GFP gene,to the retina.

Objective To analysis the quality of life of patients with active ankylosing spondylitis (AS).Methods The quality of life was assessed in 52 patients with active AS using SF-36 and was compared with the general population.The correlation between the quality of life and the clinical measures of disease,in- cluding the Bath AS disease activity index(BASDAI),Bath AS functional index(BASFI),Bath AS metrology index(BASMI),patient's global assessment(PGA),spinal inflammation,total back pain,nocturnal back pain, and enthesis index(EI),were determined.Results The patients with active AS reported significant decreased scores on all dimensions of SF-36.The score of physical health components was poorer than that of mental health components.BASFI was the strongest factor correlated with the score of SF-36,followed by BASDAI and PGA.BASMI and total back pain were correlated with three dimensions only.In multivariate regression analysis,BASFI showed relative closer relationship to the qulity of life with active AS than other clinical mea- sures of disease and it accounted for 50.3%,35.2% and 47.9% of the variance in the physical health compo- nents,the mental health components and the overall score of SF-36,respectively.Conclusion The quality of life in patients with active AS is significantly declined compared with general population.The physical aspects seem to be more severely affected.Functional status of the patients with active AS are correlated with the quality of life closely.

Inositol requiring enzyme 1 alpha (IRE1α), a widespread transmembrane protein in mammals, is an endoplasmic reticulum stress (ER stress) receptor. Among the three signaling pathways of the unfolded protein response (UPR), the IRE1α pathway is the most conservative. And there is a growing body of evidence that the occurrence and development of tumors is closely related to the over-expression of IRE1α. Therefore, the study of the IRE1α inhibitors is of great significance to the discovery of new anti-tumor drugs and has been attracting more and more attention. In the hope of providing ideas for the research of targeting IRE1α for cancer therapy, this paper reviewed the data of representative IRE1α inhibitors, including inhibitory activity, the mechanism of action, structural characteristics, and so on.
