Journal of Traditional Chinese Medicine 1992;0(11):-
Objective: To observe effect of combination of TCM-WM with high colonic lavement for delaying renal failure. Methods: 98 cases of renal failure at compensatory phase were randomly divided into a treatment group treated with high colonic lavement, twice each week. 2 hours each time, and a control group treated with oral administration of coated aldehyde oxystarch,10g each time, thrice each day, 3 months constituting one course. Results: After lavenment. symptoms were improved, deceaseing velosity of the clearance rate of endogenous creatinine in blood and urine slowed lowered, renal survival rate of kidney increased, and the interval of dialasis and other replacement therapy obviously postponed in the treatment group as compared with that before treatment and the control group. Conclusion: The high colonic lavement has obvious therapeutiv effect in delaying renal failure velosity with a smaller stimulation to the stomach and smal intestine. It is an effective way for conservation treatment of renal failure.

Objective To study and compare the clinical and MR imaging characteristics of common intracranial ring enhanced lesions.Methods MR imaging studies of 65 intracranial ring enhanced lesions were reviewed retrospectively. The lesions included 17 glioblastomas, 17 metastasises, 12 brain abscesses, 8 acoustic neurinomas, 7 craniopharyngiomas, 3 neurocysticercosises, 1 malignant lymphoma. All cases were confirmed by surgery and pathology. Results The ring enhancement of tumors presented heterogenous thickness of thick walls and irregular forms. Among them, the highly malignant tumors appeared very obviously heterogeneous thickness of the walls, especially the inner walls were uneven and coarse. While the ring enhancement of the non-tumor lesions usually were of homogeneous thickness of the walls, regular shapes and smooth inner walls. Conclusion The different patterns of intracranial ring enhanced lesions on MR can supply important diagnostic information. Combining the patients' history, age, location and the information of magnetic resonance imaging, we may make correct diagnosis.

Objective To determine the added clinical applications of MR virtual endoscopy (MRVE) plus MRCP in cholangiopancreatography. Methods In 14 month, 44 patients with obstructive jaundice and symptomatic bile trace were assessed by MRVE in biliary tract.The 2D data of heavily T 2 weighted images with FSE(non breath hold, respiratory trigger) and SSFSE(breath hold, multi slice single shot fast spin echo) sequence were transferred to the computer workstation. Navigator software (GEMS) was used to display intraluminal views of the pancreaticobiliary tract with a surface rendering technique. Results Patients suffered from neoplasm ( n =18), bile stone (17), postoperative complications of cholecystectomy( n =3), and other disease of biliary tract( n =6). MRVE could clearly demonstrate the anatomical structures in biliary tract, extended pancreas tract,biliary meatus narrowing and obstruction, bile duct stones, duct branches, and the inner wall of pathological obstruction.The main limitation of virtual endoscopy was inability to evaluate mucosa and lack of histological diagnosis. Sensitivity for detection of bile duct dilatation and site of obstruction was: 2D FSE 91 7%, and SSFSE 97 9%. Conclusion MRVE provided noninvasively endoscope like display of biliary tract.Its display ability was a supplement to image biliary trace. MRVE effect of multi slice SSFSE sequence was better than that of fast spin echo.
