Objective To evaluate the effects of application of MgCI2, ATP, and ATP-MgCl2 on the funcrions of liver, kidney, heart and lung in experimontelly ischemic injuried animals, and to study the therapeutic role of exogenous Mg2+ and energy on repairmat of this injuny ming. Freeze etching, Histochemistry, Atomic Absorhtion Spectrum (AAS) and combine LM and EM. The experiment showed that MgCl2 and ATP protectived functions damnify organic (P>0.01) ,ATP-MgCl2 protected effect it notable results (P<0.01 ). Cell membrance was complete, glycogen became enriched in the cytoplasm, the uniform-distributed protein granule on Pside of plasma membtance of cell was found. There were positive material in the membrances and similar to normal group, cell michondia calcium decreased. Conclusions The exogenous application of ATP-MgCl was beneficial to the critical patient.

Objective To evaluate the determination of glomerular filtration rate (GFR) by non-ionic contrast medium iohexol plasma clearance. Methods GFR of 93 patients, 45 male and 48 female, age ranged from 12 to 80, with different renal functions was determined. The patient underwent an overnight fast and 5 ml of iohexol was injected into peripheral vein in the morning. 2 ml plasma sample was collected 4 hours after injection, and plasma concentration of iohexol was measured by high performance liquid chromatography(HPLC) . The iohexol plasma clearance was calculated by two one-compartment model; Jacobsson's and Bubeck's model. 99mTc clearance was used as the reference method. Results Iohexol-GFR obtained by Jacobsson's model vs 99mTc-GFR yielded a correlation of r = 0. 85, standard error of the estimate (SE) = 16. 06 ml/min. There was also a high correlation between iohexol-GFR obtained by Bubeck's model and 99mTc-GFR, r = 0. 82, SE = 17. 75 ml/min. In the patients in early stage of renal failure, iohexol-GFR was the most sensitive indication as compared to Scr and Ccr. Conclusion Iohexol plasma clearance calculated by Jacobsson's and Bubeck's models is a simple and accurate method of determining GFR.

ObjectiveTo study the etiology, preoperative diagnosis and treatment of nonocclusive mesenteric ischemia(NOMI). MethodsClinical data of 3 cases of NOMI from 1992 to 1998 were analyzed retrospectively. ResultsMajor clinical presentations were abdominal pain, gastrointestinal bleeding and abdominal irritation. None was correctly diagnosed preoperatively. Partial ileectomy in 2 cases and right colectomy in 1 case was performed with a mortality of 2/3. Conclusion Early diagnosis and accurate assessment of the bowel viability in exploration were quite difficult. Resection of the infarcted bowel or ′second-look procedure′ were recommended if necessary.

Objective To evaluate the applicability of the simplified equation of MDRD to predict glomerular filtration rate(GFR)from serum creatinine in Chinese patients with chronic kidney disease(CKD),and refit the MDRD equation parameter estimates with Chinese patients data.Methods A total of 760 hospitalized CKD patients were investigated from 2002 to 2005.Patients'sex,age,height and body weight were recorded;plasma creatinine and ~ 99m Tc-GFR(standardized by body surface area)were measured in all patients;GFR was estimated with simplified equation of MDRD and Cockcroft-Gault;the accurancy of estimated GFR with MDRD and CG were compared with~ 99m Tc-GFR in different stage of CKD.Totally 670 patients were randomly selected as the training sample,the remaining 90 patients constituted the validation sample.We used stepwise multiple regression to refit the equation of MDRD and the regression models were developed by using the training sample.The refitting equation was then tested and compared with the other equation in the validation sample.Results (1)Both the MDRD and CG-GFR prediction equations seemd to systematically underestimate GFR,but the accurancy of MDRD equation was better than CG-GFR in stage Ⅰ~Ⅲ of CKD.(2)The bias of estimated GFR(MDRD or CG-GFR equation)with ~ 99m Tc-GFR was lower in stage Ⅰ~Ⅲ than in stage Ⅳ~Ⅴ of CKD.(3)Refitting of the MDRD equation parameter estimates to Chinese patients data set resulted in the following prediction equations:GFR=234.96?(Scr)~ -0.926 ?(Age)~ -0.280 ?0.828(Female).(4)Comparing with~ 99m Tc-GFR,the bias of estimated GFR calculated by the refitting MDRD equation was lower than that of estimated with MDRD or CG especially in the stage Ⅳ~Ⅴ of CKD in Chinese patients.Conclusion the simplified equation of MDRD can estimate GRF accurately,but the equation must be refitted in Chinese patients.

The evaluation of glomerular filtration rate is important in the diagnosis,treatment, and prognosis for patients. Although there are different equations widely used and convenient,the accuracy of them on the specific populations, including diabetic patients and the elderlys, still needs further discussion. We recommend using the Chronic Kidney Disease Epidemiology Collaboration ( CKD-EPI) from creatinine and cystatin C in the elderlys. For diabetic patients, however, this equation should be recommended with cautions.

Objective To analyze the technique and clinical effect of percutaneous nephrolithotomy combined with endoscopic balloon dilation in the treatment of upper ureterostenosis with recurrent renal calculi.Methods From February 2009 to May 2012,20 ureteral stenosis patients with the history of ureteral open surgery,postoperative residual or recurrent kidney renal calculi were treated.Fifteen cases were with hydronephrosis of 2-4 cm,4 cases were with hydronephrosis of 5-6 cm and 1 case was with hydronephrosis ＞ 6 cm.Subsequent calculi size ＜ 1 cm was found in 16 cases,1-3 cm in 3 cases,＞ 3 cm in 1 case.All patients were treated with percutaneous nephrolithotomy ultrasonic lithotripsy combined with balloon dilatation.The calculi clearance rate,hydronephrosis changes,complications,intraverous urography (IVP) and CT urography (CTU) situation before and after surgery were analyzed.Results All the 20 cases were completed surgery successfully.There was 1 case with renal hemorrhage 3 d after surgery and controlled with DSA hemostasis.There was 1 case accepted adjusting double-J tube by ureteroscopy.Seventeen patients'calculi were completed removed.Two cases with residual calyceal calculi size ＜ 5 mm was not further treated.There was 1 case treated with nephrectomy because of renal calculi with infection.The patients were followed up for 6-39 (12.5 ± 1.9) months.Hydronephrosis improved significant changes [2.1-4.0 (2.2 ±0.9) cm vs.2.5-7.5 (3.9 ± 1.2) cm,P ＜ 0.05].All patients achieved significant improvement in IVP and CTU comparing of preoperative and postoperative data.Conclusion The use of percutaneous nephrolithotomy combined with endoscopic balloon dilation is a safe and effective treatment option in the treatment of kidney calculi with ureteral stenosis.

Objective To observe 125I seed treatment effect and environmental radiation in the treatment of recurrent glioma.Methods 64 patients with recurrent glioma patients,according to the wishes of patients and their families were divided into observation group of 30 cases and a control group of 34 patients.Clinical outcomes and follow-up of 125I seeds around radiation were compared between the two groups.Results The treatment efficiency of observation group and control group was 60.0％ (18/30),and 35.3％ (12/34),respectively,which was statistically significant(x2 =8.39,P ＜0.05).Follow-up from 0 to 6 months,the ambient radiation rapidly decreased as the distance increaseing with the implantation point,radiation dose in a distance of 40cm has been close to the natural basis of radiation dose;125I seeds measured radiation dose continued to decay with increasing time after implantation.Four months later,it was close to the natural basis of radiation dose.Conclusion Conclusion 125I radioactive particles in the treatment of recurrent glioma have good curative effect.The effects of radiation on the surrounding environment crowd are easily protected.
