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 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.

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.

Unilateral hip and knee arthroplasty were performed at the same time, strengthen the management of incisions and catheters after the operation, actively prevent complications, and guide patients to perform functional rehabilitation exercises under the conditions of good pain management and safe coagulation factor activity; pay attention to the nursing of coagulation factor replacement treatment in the whole perioperative period.Results:After careful nursing, no serious complications occurred during the patient's hospitalization, and the position and force line of the prosthesis were satisfactory by imaging examination before discharge.Conclusion:The perioperative care of this patient proved that the above-mentioned nursing measures are effective for hemophilic arthritis patients with hepatitis C undergoing unilateral hip and knee arthroplasty at the same time.

Objective: To obtain the antibody against N terminal of 1A6/DRIM, and thereafter get the profile of 1A6/DRIM expression in different cell lines. Methods: The N terminal of 1A6/DRIM (aa 577 714) was cloned into pGEX 4T 3. Multiple antigenic peptides (MAPs)(aa638 661) was synthesized as the antigen with Fmoc/PyBOP method. Rabbits were immunized by injecting the MAPs and the immunized sera were analyzed with ELISA and Western Blot. The Western Blot and immunofluorescence were performed to analyze the expressing profiles of the 1A6/DRIM in different tumor cell lines. Results: The antibody specifically recognized the full length of 1A6/DRIM as a 310 kDa band, which was also recognized by C terminal monoclonal antibody shown by Western Blot. 1A6/DRIM is expressed in multiple tumor cell lines and mainly located in the nuclei. Conclusion: Preparation of the antibody with MAPs is a useful technique when the fusion proteins can not be induced in E coli . The antibody we got via MAPs has supplied a good tool for further studies on the functions of the novel gene 1A6/DRIM.

Objective To evaluate glycemic control,complication and influence factors of glycosylated hemoglobin(HbA1c) in type 2 diabetic(T2DM) patients with hypertension in retired and veteran of military communities in Kunming.Methods Cross-sectional study was conducted and 216 T2DM patients with hypertension were enrolled in current study.A self-made questionnaire was used to collected information including age,course of the disease,complication,hypoglycemic agents and status of glucose controlling.The levels of HbA1 c,fasting blood-glucose (FBG),2h postprandial blood glucose (2hPBG),total cholesterol (TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol (LDL-C),Blood urea nitrogen(BUN),creatinine(Cr) and uric acid(UA) were measured.Relative factors of HbA1c were analyzed.Patients were divided into the standard (HbA1c ＜ 7％) and substandard groups (HbA1c ≥ 7％) according to the level of HbA1c,and divided into the oral-medication,insulin-treatment and oral medication combined insulin groups according to therapeutic regimens.Results The goal attainment rate of HbA1c(HbA1c ＜7％) in retired and veteran of military communities in Kunming was 44.9％ (97/216).The levels of FBG,postprandial plasma glucose(PPBS) and TG in standard group were (6.1 ± 1.2) mmol/L,(9.4 ± 1.8) mmol/L and (1.9 ± 1.3) mmol/L,significant different from those in substandard groups [(7.8 ± 1.6) mmol/L,(11.5 ±2.2) mmol/L and (2.4 ± 1.3) mmol/L],and the differences were significant (t =11.6,9.1,2.2; P ＜ 0.05 or P ＜ 0.01).Meanwhile,the rate of cardiovascular disease,cerebrovascular disease,proteinuria,peripheral neuropathy and retinopathy were 69.8％,34.5 ％,20.5％,20.5％,29.6％,respectively,significantly different between the standard and substandard groups (P ＜ 0.05).HbA1 c level was linear correlated with FBG (r =0.76,P ＜ 0.01),PBG (r =0.61,P ＜ 0.01),TG (r =0.24,P ＜ 0.05) and the frequency of glucose monitoring (r =-0.55,P ＜ 0.01).As the increasing of the stage of diabetes,the selected therapeutic regimen were oral anti-diabetic agents,followed by insulin and insulin combined oral antidiabetic agents.The levels of PBG and serum creatinine in patients with insulin monotherapy were higher than those in other groups (P ＜0.05).Conclusion The level of glucose controlling of retired and veteran of military communities in Kunming is better.The prevalence of diabetic chronic complications is higher in patients with poor glucose controlling.HbA1c level is correlated with FBG,PBG,TG and the frequency of glucose monitoring.Oral antidiabetic agents is the primary therapeutic regimen.
