Objective To evaluate the clinic value the technique of Cuboid stereotactic catheter (TCSC) in the treatment of small-volume traumatic extradural hematoma in non-functional areas.Methods We performed a retrospectively analysis of 65 patients with small-volume(15-30 mL) traumatic extradural hematoma in non-functional areas. All of which were divided into two groups according to the different treatments. 35 cases treated with drugs were control group, while the rest of 30 cases with both drugs and TSCS were treatment group. The complication incidence and hematoma clearance rate in hospitalization time, recurrence rate of headache, anxiety,hematoma clearance rate at 3 and 6 months follow-up were compared between the two groups.Results The hematoma clearance rate in control group and treatment group were 25.7% and 66.7%,respectively. (P=0.001), while the complication rate was no obvious differences. The recurrence rate of headache, anxiety and hematoma clearance rate at 3 months follow-up were different between the two groups. These conditions were not happened at 6 months follow-up.Conclusion TCSC may eliminate the hematoma within a short hospitalization time by avoiding extra complication coincidence, improve the short-term life quality of patients such as relief the symptoms like headache and anxiety in the patients with small-volume(15~30 mL) traumatic extradural hematoma in non-functional areas. Above of results indicates the impact of this technique on neurosurgical practice.

:23-25
 
目的 探讨A超和IOL Master测量人工晶状体度数的精确性,为白内障手术提供客观的临床数据。方法 选取300例300眼老年性白内障患者,术前采用A 超和IOL Master测量眼轴长度、自动验光仪测量角膜曲率,A超组利用自动验光仪的角膜曲率数据,IOL Master组利用仪器自带的角膜曲率数据,均使用SRK-T公式计算需要植入的人工晶状体度数,观察术后3 m的屈光状态,使用自动验光仪检测患者屈光状态并分析。结果 所有被列入研究的患眼随机分为A超组和IOL Master组, A超组测得的平均眼轴长度为(23.21±0.59)mm,IOL Master组测得的眼轴长度为(23.22±0.59)mm,两组数据对比差异无统计学意义(P>0.05);利用自动验光仪测量的术前平均角膜曲率为(44.01±1.79)D,利用IOL Master测量的术前平均角膜曲率为(44.13±1.62)D,两者比较差异无统计学意义(P>0.05);A超组和IOL Master组术后的平均绝对屈光误差(mean absolute refractive error,MAE)分别为(0.43±0.26)D、(0.42±0.17)D,两组比较差异无统计学意义(P>0.05)。结论 IOL Master在操作上略优于A超,但在人工晶体度数测量上与A超比较没有发现明显优势,不能完全取代A超,两者结合更能确保人工晶体度数测量的精确性。
Objective By discussing the accuracy of A-scan and IOL Master in intraocular lens power measurement, to offer Objective clinical data for cataract surgery.Methods Three hundred patients(300 eyes)with age-related cataract were included in the study. Before surgery,axial length was measured by A-scan and IOL Master respectively and corneal curvature was measured by auto refractometer. A-scan group used the corneal curvature data of the auto refractometer. IOL Master group used the corneal curvature data from the instrument. Intraocular lens power was calculated according to the SRK-T formula.We observed the refractive state of 3m after operation, detected and analyzed the patient's refractive data by the auto refractometer.Results All patients who were included in the study were randomly divided into A-scan group and IOL Master group.The mean axial length was (23.21±0.59) mm measured by A-scan, the mean axial length was (23.22±0.59) mm measured by IOL Master. There was no significant difference between them (P>0.05). The preoperative mean corneal curvature measured by the auto refractometer was (44.01±1.79)D. The preoperative mean corneal curvature measured by IOL Master was (44.13±1.62)D. There was no statistically significant difference between them (P>0.05). The mean absolute refractive error ( MAE) in A-scan group was (0.43±0.26)D and in IOL Master group was (0.42±0.17)D. There was no statistically significant difference between them (P>0. 05).Conclusion IOL Master group operated slightly better than A-scan group, but we did not find a significant advantage in intraocular lens power measurement with A-scan group. IOL Master may not completely replace A-scan. The combination of the two ensures the accuracy of the measurement in intraocular lens power.

Objective Few studies has been conducted concerned Glomerular Filtration Rate(GFR) estimationequations about Cockcroft-Gault equation(CG equation)and Chinese Modification of Diet in Renal Disease equation(c-MDRD equation)in systemic lupus erythematosus(SLE). Our study aims to assess performance of two equations for renal function evaluation in patients with SLE.Methods 193 participants were enrolled in this study. Measured GFR was obtained by renal dynamic imaging method and Serum Creatinine (SCr)was determined for each participant. eGFR was gained by CG equation and c-MDRD equation respectively. Performance of equations were compared from different aspects.Results mGFR(median), eGFR-CG(median), eGFR-cMDRD(median)of the 193 participants were 75.01,70.22,70.67 mL/(min·1.73 m2)respectively. The participants were divided into two groups including mGFR≥60 (n=108)as well as mGFR<60 mL/(min·1.73 m2)(n=85). For overall participants, bias for CG equation and c-MDRD equation were 0.64, 3.91 mL/(min·1.73 m2) respectively. In terms of precision and accuracy, CG equation was better than c-MDRD equation. In subgroup, CG equation was still superior to c-MDRD equation except for bias in CG equation which is higher than c-MDRD equation in mGFR<60 ml(min·1.73 m2).Conclusion Compared with c-MDRD equation, CG performed better in GFR estimation in patients with SLE.

Objective: To discuss the value of ADMIRE reconstruction technique in the liver plain CT scan by the comparison of displays to the liver separately by ADMIRE and traditional FBP reconstructions after DSCT scan. Methods: 48 patients who were clinically doubted to have hepatic lesions were scanned by DSCT in liver, then six groups of images for FBP and ADMIRE 1-5 on the average CT value, noise, signal to noise ratio ( SNR ), contrast to noise ratio (CNR) and subjective scoring on image quality were compared. Results: 6 groups of images were compared,and the average CT value of liver parenchyma has no statistical differences (P>0.05);The differences were statistically significant (P<0.05)on noise, SNR, CNR and subjective scoring,ADMIRE5 reconstruction has the least noise and the largest SNR and CNR.For the images of ADMIRE1 and ADMIRE5, the image subjective scoring is lower than that by FBP; for the images of ADMIRE2 and ADMIRE4, the image subjective scoring is higher than that by FBP; and ADMIRE-3 has the highest score.But for the rate of lesion detection, all the images were the same. Conclusion: ADMIRE reconstruction strength 3 makes the best image quality.ADMIRE reconstruction can decrease noise and improve SNR and CNR,as well as have a potential effect decreasing the scan dose.
