Objective To analyze the relationship between pre - pregnancy body mass index ( BMI) ,gestational weight gain ( GWG) and the birth weight of infants,and explore the effect of weight change before and during pregnancy on low birth weight ( LBW) and macrosomia. Methods Women were enrolled by the Chinese Pregnant Women Cohort Study during first trimester. Each respondent's weight before and during pregnancy and the birth weight of infant were collected after fellow up. Prepregnancy BMI was divided into underweight,normal and overweight /obesity groups and GWG was divided into suitable, insufficient and excessive groups. Multivariate Logistic regression was adopted to explore the relationship be- tween pre-pregnancy BMI,GWG and newborn's birth weight. Results Women's prepregnancy BMI and GWG were associated with neonatal birth weight ( all P<0. 05) . Prepregnancy overweight or obesity ( OR=2. 339,95% CI: 1. 674-2. 282,P<0. 001) and excessive GWG ( OR= 1. 398,95% CI: 1. 188-1. 978,P= 0. 048) were shown as risk factors for macrosomia. Insufficient GWG increased LBW risk ( OR = 1. 479, 95% CI: 1. 461-1. 679,P= 0. 035) while excessive GWG declined LBW risk ( OR= 0. 428,95% CI: 0. 225 -0. 817,P= 0. 010) . Under weight-insufficient GWG was risk factor of LBW ( OR= 1. 335,95% CI: 1. 048 -2. 319,P= 0. 048) while normal BMI-excessive GWG ( OR= 1. 088,95% CI: 1. 016-1. 675,P= 0. 038) and overweight /obesity-excessive GWG ( OR= 1. 498,95% CI: 1. 244-2. 017,P= 0. 046) were associated with higher risk of delivering macrosomia. Conclusions Prepregnancy BMI and GWG were associated with infant's birth weight and women were suggested to maintain their weight in recommended range before and during pregnancy.

Microscopic identification and NIRS methods were applied to identify Clematidis Radix et Rhizoma of two different origins. The results showed that both methods could identify the samples. NIRS could identify the two samples nondestructively, and provides a basis for establishment of a standard herbs radix clematidis NIRS fingerprint in the future.

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 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.

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.

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.
