Objective To investigate the semen variation of the uremia patients after renal transplantation. Methods The semen samples from 10 uremia patients before (group A) and after (group B) renal transplantation and 12 normal volunteers(group C) were analyzed,and the main semen parameters of the 3 groups were compared. Results The mean sperm motilities of groups A,B and C were (13.8? 2.8 )%、(48.3?7.2)% and (63.8?3.6)%,respectively,the vitalities were (24.2?4.1)%、(76.3?3.9)% and (80.4?2.2)%,and the normal sperm morphologies were (15.6?2.3)%、(17.7?1.9)% and (33.8?3.7)%.The sperm motility and vitality of group B were significantly improved than group A(both P 0.05). Conclusions The successful renal transplantation can improve the semen parameters of the uremia patients.

Objective To explore the safety, feasibility, and techniques of hand-assisted laparoscopic splenectomy (HSLS) for massive splenomegaly. Methods Between January 2005 and December 2006, 40 patients with massive splenomegaly owning to portal hypertension were treated with HSLS or open splenectomy (OS). The two groups were comparable in age, sex, hepatic function by Child classification, and size of the spleen. Results No serious complications occurred in both the groups. Compared with the OS group, patients in the HALS group had more blood loss [ (312?61) ml vs (235?105) ml, t=2.583, P=0.014], longer operation time [(95?20) min vs (73?16) min, t=3.832, P=0.000], earlier recovery of intestinal function [(48?1) h vs (98?1) h, t=-153.093, P=0.000], and shorter postoperative hospital stay [(6?2) d vs (10?2) d, t=-6.124, P=0.000]. Conclusions HSLS is feasible and safe for patients with massive splenomegaly. Despite a longer operation time, the procedure is superior in postoperative recovery.

Objective To discuss the application value of DWI and ADC on predicting therapeutic effect of radiotherapy treatment in NPC. Methods Twenty four local recurrent cases and 38 non-recurrent cases after radiotherapy treatment in NPC were reviewed. MRI and DWI-MRI were performed at pre-radiotherapy and 3, 6, 12 months after treatment, the ADC values of the lesions were analyzed by SPSS 18.0 statistical software. ROC curves based on the ADC values were measured in 3, 6, 12 months after treatment plotted to analyze the threshold ADC value for confirming recurrence. Results The recurrent group and newly diagnosed group showed significantly high signal on DWI, while the non-recurrent group acquired low or mixed signal. The ADC values of the primary tumor in the recurrent group and the non-recurrent group were (0.709 ± 0.078) × 10-3 and (0.693 ± 0.089) × 10-3mm2/s, respectively, t=-0.717,P>0.05, respectively.The ADC values of the primary and recurrent tumor in the recurrent group were (0.730± 0.068) × 10-3mm2/s and (0.709 ± 0.078) × 10-3mm2/s, t=-1.000,P>0.05 , respectively.There were statistical differences between the recurrent group and the non-recurrent group for ADC in 3, 6, 12 months after treatment:(1.128 ± 0.179) × 10-3 and (1.358 ± 0.145) × 10-3mm2/s, t=5.567,P<0.01;(1.164 ± 0.174) and (1.450 ± 0.102) × 10-3mm2/s, t=7.310,P<0.01;(1.107 ± 0.180) × 10-3 and (1.584 ± 0.125) × 10-3mm2/s, t=11.189,P<0.01;respectively. Take 1.29 × 10-3 mm2/s,1.32 × 10-3mm2/s,1.37 × 10-3mm2/s respectively in 3, 6, 12months after treatment as the diagnostic threshold to predict tumor recurrence. The sensitive , specificity, and accuracy were (83.3%, 73.7%, 77.4%), (83.3%, 89.5%, 87.1%), (100.0%, 94.7%, 96.3%).Conclusions Both DWI and ADC value are important for diagnosing and predicting recurrent NPC after radiotherapy treatment, DWI and ADC can be used to regular follow-up after radiotherapy, to further improve the rate of early diagnosis of recurrent NPC.

Objective To investigate an appropriate megavoltage computed tomography ( MVCT ) protocol to guide helical tomotherapy ( HT) for multiple metastases. Methods According to the location of target volume, 48 patients with multiple metastases undergoing HT were divided into head/chest group ( n=15), head/pelvis group (n=15), and chest/pelvis group (n=18). Each target volume received MVCT scans during the treatment. The obtained MVCT images were registered to CT images and the setup errors were recorded. The CTV?PTV margins were calculated. Comparison was made by paired t test. Results In the head/chest group, there was no significant difference in the setup error in x?axis between the head and chest (-0.15±1?25 vs. -0.21±2?34, P=0?71), while the head had significantly smaller setup errors in y?and z?axis than the chest (0.73±1?22 vs. 1.56±2?54, P=0?00;0.93±1?44 vs. 2.65±1?88, P=0?00). In the head/pelvis group, the head had significantly smaller setup errors in x?, y?, and z?axis than the pelvis (-0.16±1?31 vs. -1.29±3?72, P=0?00;0.81±1?34 vs. 3.20±3?90, P=0?00;1.24±1?75 vs. 5.49±2?80, P=0?00) . In the chest/pelvis group, there were no significant differences in setup errors in x?or y?axis between the chest and pelvis (-0.25± 2?90 vs. -0.22± 3?65, P=0?06;0.35± 3?60 vs. 0.38± 3?78, P=0?87), while the chest had a significantly smaller setup error in z?axis than the pelvis (1.95±2?81 vs. 3.35± 3?05, P=0?00) . In the three groups, the CTV?PTV margins of lower target volume were reduced in three dimensions after the correction of upper target volume, in which y?axis showed the largest reduction of CTV?PTV margins (5?13 vs. 4?01;9?17 vs. 8?30;8?52 vs. 7?13). Conclusions The setup error of individual target volume should not be used for correction of the overall setup error in HT for multiple metastases with isolated target volume. An MVCT protocol that provides image?based guidance for multiple target volumes is recommended.

Objective To explore the diagnostic value of MRE for differentiating hepatic benign and malignant tumors.Methods 36 patients with liver tumor (a total of 39 lesions,including 20 hepatocellular carcinomas,7 hemangiomas,5 cholangiocellular carcinomas,3 metastases,2 hepatic angiomyolipomas,1 carcinosarcoma,1 castleman’s disease)and 9 healthy volunteers were evaluated with MRE.The elastogram were generated with FUNCTOOL post processing program.The mean value of elasticity of hepatic malignant tumors,hepatic benign tumors,hepatic parenchyma around the malignant tumors,hepatic parenchyma around the benign tumors and the normal liver of healthy volunteers were measured and compared.Results The mean value of elasticity of malignant tumors [(7.39±1.70)kPa]was significantly higher than these of benign tumors [(4.11±0.37)kPa,P < 0.001],peripheral parenchyma around the malignant tumors [(3.50±0.73)kPa,P < 0.001],peripheral parenchyma around the benign tumors [(2.61±0.45)kPa,P < 0.001] and normal liver of healthy volunteers [(2.38±0.24)kPa,P <0.001].The mean value of elasticity of parenchyma around the malignant tumors [(3.50±0.73)kPa]was significantly higher than that of hepatic parenchyma around the benign tumors [(2.61 ± 0.45)kPa,P <0.001].The mean value of elasticity of hepatic parenchyma around the benign tumors [(2.61±0.45)kPa]was slightly higher than normal liver of healthy volunteers [(2.38±0.24)kPa],and there was no significant difference between the two (P >0.05).A cutoff value of 5.08 kPa can accurately differentiate malignant tumors from benign tumors and normal liver parenchyma.Conclusion MRE could be used in diagnosis of hepatic focal tumors,which is helpful for differentiating benign and malignant liver tumors.
