A digital beamformer in medical ultrasound imaging systems conventionally requires that the returning signals received by transducers are sampled at a rate significantly higher than the Nyquist rate. This paper presents a digital beamformer that employs zero padding followed by digital interpolation filtering to achieve vernier beamformer delays. The experimental results show that the digital interpolation beamformer can greatly decrease the complexity of A/D converter circuitry.

Background Posterior capsular opacification (PCO)affects the pseudoaccommodation of 1CU accommodative intraocular lens (1CU AIOL).At present,few studies on the effect of PCO and Nd∶ YAG laser capsulotomy on intraocular shifting of 1CU AIOL are published.Objective The present study was to evaluate the effect of PCO and Nd∶YAG laser capsulotomy on the shifting of 1CU AIOL.Methods A respective serial caseobservational study was designed.Written informed consent was obtained from each patient prior to this study.Twentyfour eyes of 20 patients with PCO after phacoemulsification and implantation of 1CU AIOL were included in this study.Ocular examination was performed 3 months after IOL implantation,1 day before Nd:YAG laser capsulotomy and 3 months after Nd∶YAG laser capsulotomy to evaluate the distance corrected near visual acuity(DCNVA).The difference in the anterior chamber depths before and after administering 1％ pilocarpine topical eye drops was measured with the IOLMaster to determine the intraocular shifts of the IOL.The extent of IOL shifting was compared among 3 time points to assess the factors influencing IOL accommodation after 1CU AIOL implantation.Results The shifting amplitude of 1CU AIOL was(0.44±0.21)mm 3 months after implantation of 1CU AIOL,(0.27±0.11)mm 1 day before Nd ∶ YAG laser capsulotomy,and (0.34±0.10) mm 3 months after Nd ∶ YAG laser capsulotomy,showing a significant difference among them(F=7.180,P=0.001).The shifting amplitude of 1CU AIOL significantly declined 1 day before Nd∶YAG laser capsulotomy in comparison with 3 months after implantation of 1 CU AIOL(P =0.006).The shifting amplitude 3 months after Nd∶YAG laser capsulotomy increased slightly in comparison with 1 day before Nd∶YAG laser capsulotomy(P=0.059).DCNVA was(3.1±0.9)J 3 months after implantation of 1CU AIOL,(6.2±0.8) J 1 day before Nd ∶ YAG laser capsulotomy and(3.4±0.7) J 3 months after Nd ∶ YAG laser capsulotomy,with a significant difference among them (F =110.270,P =0.000).DCNVA was lower 1 day before Nd∶ YAG laser capsulotomy than 3 months after implantation of 1CU AIOL(P＜0.05).However,DCNVA was higher 3 months after Nd∶YAG laser capsulotomy than that of 1 day before Nd∶YAG laser capsulotomy (P＜0.05).There was no significant correlations between DCNVA and IOL movement 3 months after IOL implantation,1 day before Nd∶ YAG laser capsulotomy and 3 months after Nd ∶ YAG laser capsulotomy (r1 =-0.150,P1 =0.486,r2 =-0.320,P2 =0.122,r3 =-0.100,P3 =0.633).Conclusions The shifting amplitude of 1CU AIOL markedly declines due to PCO.No clinically significant influence of Nd ∶ YAG laser capsulotomy on the shifting amplitude of 1 CU AIOL is found.DCNVA can improve after Nd∶YAG laser capsulotomy.Multiple inter-related factors concerning pseudophakic accommodation may influence DCNVA.

Objective To evaluate the relationship between children interleukin-1 receptor antagonist gene(IL-1RN) polymorphisms and susceptibility to febrile seizures(FS).Methods Matching case-control study was carried out,blood samples from 52 patients with FS and 53 healthy children were collected.Genomic DNA was extracted and examined by polymerase chain reaction(PCR) amplification for judging IL-1RN genetype.Results Only Ⅰ/Ⅰ,Ⅰ/Ⅱ,Ⅱ/Ⅳ genetypes of IL-1RN were found in the surveyed Chinese population of Han nationality in Guangdong Province.No significant differences of these genotypes were observed in patients and controls.But the allele frequencise of Ⅰ,Ⅱand Ⅳ in patients were 95.2%,3.8% and 1.0%,respectively,while these frequencise in controls were 84.9%,10.4% and 4.7%,respectively.The allele frequency of IL-1RNⅠin patients was obviously higher than that in controls(P
