Objective To compare the pass rates of two primary hearing screening times and to determine the appropriate screening time.Methods The newborns born in 2004 and 2005 at our hospital were divided into two groups: group A and group B.Group A received hearing screening with distortion product otoacoustic emission(DPOAE) on the 3rd day after birth,while group B screened in one month after birth.The newborns who failed the initial screening were rescreened one month later.The babies with positive screening findings were referred to full auditory assessments.Results Group A(n=2 305) had pass rate 81.9% at the initial screening and 85.2% at rescreening.Group B(n=1 348) had pass rate 93.9%(?2=103.99,P

Objective To explore the action mechanism of basic fibroblast growth factor (bFGF) on vascular smooth muscle cells (VSMCs) in spontaneously hypertensive rats (SHR).Methods Ts were obtained from SHR and SD rats.The aortic VSMCs were cultured in vitro by tissue explant method.VSMCs were treated with different concentration of exogenous bFGF (0 ng/ml,20 ng/ml,40 ng/ml,60 ng/ml,80 ng/ml,100 ng/ml) for 48 h,then cell proliferation was detected by 3 (4,5 dimethylthiazol)2,5 diphenyltetrazolium bromide (MTT) colorimetric assay.VSMCs from SHR in control group were treated with bFGF (100 ng/ml) for 48h.VSMCs from SHR in treatment group were treated with bFGF (100 ng/ml) plus Proteinkinase C(PKC) inhibitor (staurosporine) for 48 h.Results After treatment with different concentration (0 ng/ml,20 ng/ml,40 ng/ml,60 ng/ml,80 ng/ml,100 ng/ml) of bFGF for 48 h,the values measured by MTT colorimetric method were 0.402 ± 0.103,0.605 ±0.090,0.696 ± 0.131,0.812 ± 0.080,0.901 ± 0.065,1.056±0.078 respectively in aortic VSMCs from SD rats,and 0.404±0.065,0.507±0.078,0.608±0.057,0.704 ± 0.107,0.812 ± 0.097,0.908 ± 0.032 respectively in aortic VSMCs from SHR.Compared with control group,the values measured by MTT colorimetric method were decreased in treatment group (P＜0.05).The proliferative effect of bFGF in aortic VSMCs from SHR was attenuated after administration of PKC inhibitor staurosporine.Conclusions Exogenous bFGF administration promotes VSMCs proliferation in SHR and SD rats in a concentration-dependent manner.PKC plays an important role in the signal transduction mechanism in VSMCs proliferation by exogenous bFGF.

OBJECTIVEThe purpose of this study was to investigate the relationship between the results of flowcytometry analyses of different clinical stage, location, pathologic grade and cell origin of oral and maxillofacial non-Hodgkin's lymphoma (NHL), and the diagnostic value of flowcytometry analysis in lymphoma.

METHODThis study analyzed 50 oral and maxillofacial NHL cases and 10 reactive lymph nodes (formalin fixed and paraffin embedded) by flowcytometry (FCM).

RESULTSReactive lymph nodes were all diploid. The diploid rate of NHL was 54%, and aneuploidy rate was 46%. There was statistically significant difference between reactive lymph nodes and NHL in the DNA ploidy status and cell cycle data (SPF, CV, S + G2/M, DI). The S phase fraction (SPF) and S + G2/M had close relationship with the grade of NHL. SPF value and DNA ploidy status had no obvious relationship with the prognosis.

CONCLUSIONThe results suggested that the FCM had diagnostic value in NHL, especially when the morphological diagnosis was difficult. Although the cell cycle data had no prognostic value, SPF and SPF + G2/M can show the proliferative status of NHL, which can help clinical doctor select therapeutic method.

Objective To discuss the characteristics and clinical results of rotating platform high flexion(RDHF)total knee replacement TKR. Methods A total of 61 patients(78 knees)including 13males(15 knees)and 48 females(63 knees)at age range of45-79 years(mean 64.3 years)were treated with Sigma(RP-HF)rotating platform high flexion total knee replacement.Osteoarthritis was found in 56patients and rheumatoid arthritis in 5.By medial parapatella approach,denervation and facet repair of the patella were done,without replacing them. Results All 78 knees were followed up for 3-16 months (mean 10.5 months).the X-ray film demonstrated no prosthesis loosening,patella dislocation or subluxation.According to the knee society scoring system,the preoperative score was 48 points(33-72 points)and the knee functional score was 41 points(28-63 points)on average.After surgery,the knee score was 97points(88-100 points),the functional score 96 points(84-99 points),and the range of motion(ROM)130.(110.-150.)on average.No spin-out or infection were detected. Conclusions The Sigma RP-HF knee system provides sufficient contact area.full range of patella locus and sufficient axial rotation,which helps reach a stable and durable high flexion performance.Our short-term clinical follow up result is good but the advantages of low wear and longevity of the Sigma RP-HF prosthesis still need further study.
