Objective To determine the relationship between chronic colonic schistosomiasis and colorectal carcinoma.Methods Expression levels of c-erbB-2 and DPC4 were detected by two-step and SP immunohistochemical method respectively in normal colonic mucosa of 15 cases,in colonic mucosa of 15 cases with simple schistosomiasis,20 cases of colorectal carcinoma with schistosomiasis and 20 cases of colorectal carcinoma without schistosomiasis.Results c-erbB-2 was expressed in each group with different levels,but the level in colonic mucosa with schistosomiasis was the highest compared to other groups,which had statistical significance(P

Objective To explore the effect of valproate(VPA) on body mass index(BMI),leptin and serum lipids in children with epilepsy.Methods (Twenty-)four cases with epilepsy were selected.BMI and serum levels of leptin,total cholesterol(TC),(triacylgly)-cerol(TG),high density lipoprotein-cholesterin(HDL-C),low density hipoprotein-cholesterin(LDL-C) after treated with VPA for 3 months and 6 months were determined.Results The levels of BMI,leptin,TC,TG,LDL-C after treated 3 months were all significantly higher than those of initial(all P0.05).Those in treated 6 months were same as levels of treated 3 months.Only LDL-C level was lower than that of 3 months and same as level of before treatment.Conclusion VPA do have efficacy to cause obesity in children with epilepsy,and most of the cases occur in the first 3 months after VPA treatment.

Ovarian endometrioma is a common form of endometriosis, which may cause infertility, dysmenorrhea and pelvic pain in women of reproductive age. Although surgery is the treatment of choice for endometriomas, recurrence poses a formidable frustration. This study investigated potential risk factors of endometriomas recurrence, aiming to better understand its pathogenesis. A total of 307 patients with endometriomas were followed up for an average of 28.6 months and the 1-, 2- and 3-year cumulative recurrence rate was 9.5%, 21.9%, and 29.2%, respectively. Twenty-one potential risk factors for endometriomas recurrence were evaluated using Cox's proportional hazards models. Total revised American Fertility Society (rAFS) score was significantly associated with higher recurrence (OR=1.858, 95% CI=1.122-3.075, P=0.016), as well as younger age at surgery (OR=0.953, 95% CI=0.915-0.992, P=0.020). Semiradical surgical treatment was defined as surgical removal of cyst plus hysterectomy with preservation of bilateral or unilateral ovary, and was a significant factor that was associated with lower recurrence than the conservative surgery (OR=0.318, 95% CI=0.107-0.951, P=0.040). Postoperative pregnancy was favorable factors for disease recurrence (OR=0.217, 95% CI=0.102-0.460, P=0.000). The results suggest that endometrioma recurrence is inversely associated with age at surgery and postoperative pregnancy, and may correlate with total rAFS score and conservative surgery method.

Objective To evaluate MR findings and clinical features in patients with spontaneous spinal epidural hematoma (SSEH). Methods Eight patients (5 men, 3 women; aged 16-50 years ) with SSEH underwent MR imaging during 1994-2001, including 7 cases without history of trauma or coagulation disorders and 1 case with history of hypertension. MR imaging was performed from 4 hours to 3 days after the onset of symptoms in all 8 patients with surgical and pathologic diagnosis. Results The hematomas were in lateral posterior or posterior epidural space, including 3 cases in cervical vertebra, 2 cases in thoracic vertebra, 2 cases in cervical and thoracic junction region, and 1 case in thoracic and lumbar part. The MRI confirmed an encapsulated hematoma caused by arteriovenous malformation in 1 case and two hematomas associated with disc herniation. The signal intensity of the hematoma varied with the hematoma age, but T 1-weighted images reflected its typical signal changes. Sagittal and coronal T 1- weighted images revealed isointense (7 cases) and slight high-intense (1 case) signal; Sagittal and axial T 2-weighted images revealed mixed-intensity (6 cases) and mixed high-intensity (2 cases). Conclusion MR imaging has an important value on localization, identification, and differential diagnosis of the lesion, therefore, it is the most helpful diagnostic tool for this condition.

Purpose To explore the effect of ultrasonic section,patient position and other factors on Young's modulus and shear wave velocity measurement of the muscle,and to study the consistency between Young's modulus and shear wave velocity on reflection of muscle hardness.Materials and Methods Shear wave elastography was used to detect 10 healthy young men and 10 women.Longitudinal and transverse detection of the Young's modulus and shear wave velocity of gastrocnemius and soleus were performed in natural ankle joint position,maximum plantar flexion and maximum dorsiflexion position.Results ① Comparison of the elasticity measurement between gastrocnemius and soleus.There were significant differences in the Young's modulus in the maximum plantar flexion and Young's modulus and shear wave velocity in maximum dorsiflexion position in longitudinal detection (P＜0.05) that gastrocnemius measurements were higher than soleus measurements.There were significant differences in Young's modulus and the shear wave velocity (P＜0.05) in natural position and maximum dorsiflexion position that soleus measurements were higher than gastrocnemius measurements.② In the positions of the ankle joints,the differences between longitudinal detection values and transverse detection values of gastrocnemius or soleus were statistically significant (P＜0.01) and longitudinal detection values were higher than transverse detection values.③ Comparison of the elasticity measurement of gastrocnemius and soleus muscle among different positions of the ankle joints.The measurement in natural position and in the maximum plantar flexion were evidently higher than that in the maximum dorsiflexion position (P＜0.01) in longitudinal detection.The maximum dorsiflexion position showed higher elasticity measurement.Only elasticity measurement in natural position and the maximum plantar flexion of the soleus was statistically different from that in the maximum dorsiflexion position (P＜0.01) that it was higher in the maximum dorsiflexion position.Conclusion The ultrasound elasticity measurements of gastrocnemius and soleus are related with the ultrasonic longitudinal or transverse section and the relative ankle positions.Moreover,there are some differences in elasticity measurements between these two muscles.should be given to all of these in quantitative evaluation of muscle hardness using shear wave ultrasound elastography.
