Objective To compare the efficacy of Lichtenstein and transabdominal preperitoneal patch repair(TAPP) in the treatment of primary inguinal hernia in adults. Methods The clinical data of 223 patients who received Lichtenste and 121 patients who underwent TAPP in our hospital between January 2002 and January 2006,were analyzed retrospectively.The efficacy and complications of the two methods were compared.Results The rate of intraoperative injury of the inner organs in the TAPP group was significantly higher than that in the Lichtenstein group [5.8%(7/121) vs 0.4%(1/223),?2=7.626,P=0.006],while no significant difference was detected in the rate of abdominal organ injury between the two groups [0.8%(1/121) vs 3.1%(7/223),?2=0.969,P=0.325].The rate of postoperative complications in the TAPP group was significantly lower than that in the Lichtenstein group [14.0%(17/121) vs 36.3%(81/223),?2=18.881,P=0.000].In the TAPP group,during a follow-up of(14?7) months,one case of recurrence was found(0.8%).Whereas in the Lichtenstein group,the patients were followed up for(16?8) months,two of them had recurrence(0.9%).No significant difference existed in the recurrence rate between the two groups(?2=0.000,P=1.000).Conclusions Both the Lichtenstein and TAPP have benefits and drawbacks.Individulized therapy is recommended for the patients with inguinal hernia.It is important for surgeons to know the indications of the operations.

Objective To investigate the effectiveness of organ dose modulation (ODM) technology with respect to dose reduction and image quality of the sensitive organs during CTA of craniocervical arteries. Methods Ninety one patients suspected of arterial vascular disease and evaluated by CTA of craniocervical arterires were enrolled in this study. Patients were divided into group A (n=46) and group B (n=45) according to the order of examination. All patients hadCTA examination of craniocervical arteries. The ODM technique was used only in plain phase in group A and was used both in the plain phase and enhanced phase in group B. The tube current in the four direction (anterior,posterior,left,right) of thyroid and orbital area and radiation dose were recorded. The image quality of group A and group B was evaluated by objective indicators [CT attenuation values and contrast-to-noise ratio (CNR) of vessels in the thyroid area and orbital region ]and the subjective score. The independent samples t test was used for the statistical analysis of the objective indicators and nonparametric rank sum Mann-Whitney U test were used for subjective score. Results For A group, There were significant differences for the tube current at all directions of the thyroid gland and orbital area between the plain phase and the enhanced phase except the current at the posterior of the thyroid gland area(P value all<0.05),and the current in plain phase lower than that in enhanced phase. The mean current of thyroid gland and the orbital area were (604±43) mA and (656± 22) mA in the plain phase and (341±54) mA and (409±63) mA in enhanced phase. The differences were significant (t values were -10.909 and -38.454,P<0.01).CTDIvol and ED were (15.6±1.4) mGy and (1.44± 0.17) mSv in the plain phase and (17.4 ± 1.4) mGy and (1.60 ± 0.18) mSv in the enhanced phase, the differences were significant (t values were - 42.008 and - 32.130, P<0.01) . There was no significant differences for the objective indicators and the subjective score between group A and group B(P>0.05). Conclusion ODM technique can provide protective effect on the sensitive organs during craniocervical CTA examination without compromising the image quality.

This paper presents the preliminary design of data acquisition system of a portable uroflowmeter. The system uses double-hole cantilever pressure sensor. The signal is transferred to ATmega644PA microprogrammed control unit (MCU), converted by A/D (analog to digital) convertor. Then the further data are processed and get the corresponding relationship of weight-time and two curves of urine flow and urinary flow rate. In the measurement accuracy of the device about urine flow, two factors about the placement and height of the data acquisition are analyzed to show the accuracy of the equipment through the Origin 8.0 data analysis software. The design is characterized by low cost and high speed of data collection, real-time, high accuracy.

Objective To investigate the influence of low-tube current in combination with simultaneous iterative reconstruction algorithm on bone mineral density (BMD) of T12 and image quality with a chest phantom.Methods An adult male chest phantom was selected.CT scan of the chest was performed at tube voltage of 120 kV and five different tube currents (20,30,40,50,60 mAs) in combination with filtered back projection (FBP),iDose4 (Level 4) and iterative model reconstruction (IMR,Level 2),respectively.BMD of T12 in chest phantom and objective evaluation results on different tube currents and simultaneous iterative reconstruction techniques were compared.The subjective scoring of mediastinum and lung window imaging qualities at tube current of 20 mAs with IMR and tube current of 60 mAs with FBP were compared.The consistency between two observers was evaluated.Results There was no significant difference between BMD values nor CT values on different tube currents and simultaneous iterative reconstruction techniques of chest phantom (all P＞ 0.05),but the differences between SD values were statistically significant (P＜ 0.001).SD values obtained with IMR were lower than those of iDose4 and FBP at same tube currents (all P＜0.001).At tube current of 60 mAs with FBP,the consistency of two observers in mediastinum window was the best (Kappa=1,P＜0.001),while in lung window was medium (Kappa=0.64,P=0.002).At tube current of 20 mAs with IMR,the consistency of two observers in mediastinum window was medium (Kappa=0.64,P=0.002),while in lung window was the best (Kappa=1.00,P＜0.001).Conclusion Low-tube current in combination with simultaneous iterative reconstruction algorithm can reduce radiation dose without affecting the accuracy of BMD.

Objective To investigate the reproducibility and accuracy of spinal BMD (bone mineral density) by low mA using adaptive statistic iterative reconstruction based on phantom model.Methods European spine phantom (ESP) was scanned with 5 different tube currents (40,60,80,100 and 120 mA) on the GE Revolution prototype.All data were transferred to the quantitative CT (QCT) PRO workstation for measuring the bone mineral density (BMD).And all data were reconstructed using different adaptive statistical iterative reconstruction veo (ASiR-V) weighting percentages from ASiR-V 0 filtered back projection(FBP) to ASiR-V 100％,at interval of 20％.Quantitative measurements of CT value,noise,and contrast noise ratio (CNR) of L1,L2 and L3 were measured in each group.The singlefactor analysis of variance (ANOVA) was used to compare the bone mineral density values of different mA and ASiR-V weighting percentages.Results Volume CT dose index(CTDIvol) and dose length product (DLP) were positively correlated with tube current(r =1).The BMD of ESP phantoms had no statistically significant differences among the multi-center lumbar spines L1,L2 and L3 at different doses under the same ASiR-V weighting percentages (P ＞ 0.05),as well as at the same dose under different ASiR-V weighting percentages(P ＞ 0.05).The error of bone density accuracy was within 6％.Conclusions Low dosage of 120 kV and 40 mA using ASiR-V without affecting the accuracy of BMD has the potential effect to reduce radiation dose without compromising image quality.
