Objective To compare the effect and adverse reaction of ultrasound-guided ESWL and UPL in the treatment of ureteral stones.Methods According to the different treatment method,80 patients with ureteral stones were divided into URL group and ESWL group.The effective rate and the incidence rate of complications were compared between the two groups.Results In ESWL group,the success rate for upper gravel was 92.3％,the success rate of lower ureteral stone lithotripsy was 55.6％,there was significant difference between them(x2 =0.049,P ＜ 0.05).In UPL group,the success rate of lower ureteral stone lithotripsy was 96.0％,and the total success rate of stone was 87.5％,while those in ESWL group were 55.6％ and 75.0％,the differences were significant between the two groups(x2 =0.001,0.032,all P ＜ 0.05),but there was no significant difference in the success rate of upper gravel between the two groups(P ＞ 0.05).The incidence rate of hematuria in ESWL group was 82.5％,which was significantly lower than 97.5 ％ in the UPL group (x2 =0.034,P ＜ 0.05).The incidence rates of fever,pain in renal region,nausea and vomiting were 17.5％,42.5％,37.5％ in the ESWL group,which were significandy higher than those in the UPL group (x2 =0.023,0.033,0.004,all P ＜ 0.05).Conclusion Compared with ESWL,UPL has high success rate of lower ureteral stone lithotripsy,less complications.

Objective To evaluate renal vascular damage (RVLs) and detect the expression of miR-145 in children with lupus nephritis (LN).Methods Clinical data of 41 cases of LN diagnosed by renal biopsy from the children with systemic lupus erythematosus (SLE) were collected. Glomerular damage score and RVLs were evaluated. The children were divided into groups according to RVLs score and pathological pattern. In situ hybridization was performed to detect the expression of miR-145 in kidney blood vessel. Differences in RVLs, miR-145 expression in the renal blood vessels and glomerular damage score were observed among the groups with different renal pathological pattern. Differences in clinical parameters, glomerular damage score and miR-145 expression in the renal blood vessels were investigated among groups with different RVLs. Results Among the groups with different pathological pattern, there was no difference in RVLs (P>?0.05) while signiifcant different were found in the expression of miR-145 and glomerular damage score (P??0.05) while a statistical different was found in the expression of miR-145 (P?

0.975). The deviation of medical decision level was within 1.6. Conclusion Comparison among various analyzers were improved after the other analyzers corrected by the one comparable analyzer through the result of the fresh serums determined by it.

Objective To explore the change of serum high-sensitivity cardiac troponin T(hs-cTnT),myoglobin(MYO),creatine kinase isoenzyme(CK-MB)mass(CK-MB mass)and N-terminal pro-brain natriuretic peptide(NT-proBNP)levels in the patients with renal dysfunction.Methods The inpatients with renal dysfunction(excluding cardiac and skeletal muscle diseases)in our hos-pital were collected and divided into the compensation period group(30 cases),decompensation period group(24 cases)and uremia group(22 cases)according to serum urea and creatine concentration,and 36 healthy individuals were selected as the control group. Venous blood was collected on an empty stomach and separated for obtaining serum.Serum levels of hs-cTnT,MYO,CK-MB mass and NT-proBNP were measured by the electrochemiluminescent immunoassay.Results Serum hs-cTnT levels in the compensation period group,decompensation period group,uremia group and the control group were 16.4(10.9-24.2),17.0(13.0-25.5),25.9 (16.5-33.8),13.7(9.4 -19.7 )pg/mL respectively.Serum MYO levels were 52.4 (40.0 -96.5 ),87.9 (57.7 -118.3 ),115.7 (94.2-175.8),34.8(24.3-48.1)ng/mL,respectively.Serum CK-MB mass levels were 1.03(0.82 -1.75),1.31 (1.08 -1.69), 1.66(1.01-2.46),1.88(1.63-2.43)ng/mL,respectively.Serum NT-proBNP levels were 292.5(123.3-576.2),363.3(192.3-893.3),1 357.2(536.5 -4 662.9),110.3 (70.1 -196.3)ng/mL,respectively.The serum hs-cTnT,MYO and NT-proBNP levels were increased with renal function decrease.The nonparametric Kruskal-Wallis H test showed statistically significant difference a-mong groups(H =14.46,49.81 and 35.00,P <0.05 ).The CK-MB mass level had no statistically significant difference among groups(P >0.05).Conclusion The patients with renal dysfunction have the higher risk rate for complicating the cardiovascular e-vents.Early detection of cardiac markers conduces to the diagnosis of myocardial injury,the evaluation of the risk rate of myocardial infarction occurrence in future and the diagnosis of heart failure and evaluation of the risk rate of heart failure occurrence in future.

Objective To evaluate the clinical effects of endovascular angioplasty and stenting for the treatment of TASC B,C arteriosclerotic occlusion(ASO) of lower extremity.Methods After the identification of the occlusion by angiography via femoral artery access by Seldinger method,the occluded arteries (mean length 7.5cm; range 1~20 cm) in 40 patients(47limbs) were treated by percutaneous transluminal angioplasty and stent placement. Results The primary recanalization was successful in 45 of 47 limbs. The technical successful rate was 96%. Thirty one self-expanding stents were deployed. PTA without stent placememt was performed in 16 limbs(of them,11 were blow knee).The ankle brachial pressure index (ABI) increased from (0.36?0.14) preoperatively to (0.82?0.15) on the 7th postoperative day. All patients were follow-uped for 1 to 48 months. Stents were occluded in 4 patients. Restenosis was observed in 1 limbs. All of the rest remained patent in the follow-up period.Conclusion Endovascular angioplasty and stenting can be an effective method for the treatment of long segmental (including below-knee) arteriosclerotic occlusion of lower extremities.

BACKGROUND:The elastic modulus of the fiber post is close to that of the dentine, so they can form a homogeneous whole and share the masticatory force, which can ease the stress concentration of dentine and prevent from tooth fracture. OBJECTIVE:To observe clinical effects of anterior teeth with flared root canals restored by fiber posts using three application methods. METHODS:Anterior teeth with flared root canals from 48 patients were involved. They were divided into three groups, then restored with three post-core crowns respectively: a single fiber post, rehabilitation with composite resin, and fiber post combined with accessory post. Al patients were folowed up for 2 years to observe post and core loosening, fracture and root fracture. RESULTS AND CONCLUSION:The group of a single fiber post was failed in eight teeth including four cases of post and core loosening and four cases of post and core fracture, with a successful rate of 64%. The group of rehabilitation with composite resin was failed in three teeth including two cases of post and core loosening and one case of post and core fracture, with a successful rate of 90%. The group of fiber post combined with accessory post was failed in two teeth of post and core loosening, with a successful rate of 93%. The successful rate of the group of a single fiber post was lower than that of the groups of rehabilitation with composite resin and fiber post combined with accessory post (P < 0.05) . The difference between the groups of rehabilitation with composite resin and fiber post combined with accessory post was not statisticaly significant (P > 0.05). The clinical effects of rehabilitation with composite resin and fiber post combined with accessory post are better than that of a single fiber post. But the method of combination fiber post with accessory post is recommended because of easy operation.

Objective To discuss the effects of applying electric heating pattern instrument in experimental teaching of fixed partial denture technology.Methods Totally 98 prosthodontic undergraduates of 2008 and 2009 grades were selected in this study； 46 students of 2008 grade were taken as control group and 52 students of 2009 grade were taken as experimental group.Students in experimental group made wax patterns with electric heating pattern instruments to melt inlay wax while those in control group made wax patterns with instruments heated by alcohol lamps.Teaching effects were evaluated by experimental test scores and questionnaires.Results Test scores of experimental group were (22.6± 1.8),obviously higher than those of (22.6-± 1.8) in control group (P ＜ 0.05).Satisfaction degree of experimental group were increased significantly compared with that of control group based on the resuits of questionnaire.Conclusions Applying electric heating pattern instrument in making wax patterns in experimental teaching of fixed partial denture technology is easy to operate and can improve the quality of wax pattern and working efficiency as well as enhance students' confidence,therefore it is worthy further spreading.

BACKGROUND:The elastic modulus of the fiber post is close to that of the dentine, so it can form a homogeneous whole and share the masticatory force, which can ease the stress concentration of dentine and prevent from tooth fracture. ＜br> OBJECTIVE:To investigate the effect of alveolar bone height and fiber post length on the fracture resistance of endodontical y treated maxil ary central incisors. ＜br> METHODS:Forty-eight human maxil ary central incisors were assigned randomly to six groups (n=8) of three different post insertion depths (5, 7, 9 mm) and two alveolar bone levels (2 and 5 mm) from the cement-enamel junction. Al of them were restored by glass fiber posts with composite resin core and cast metal crown. The samples were loaded in a testing machine with a crosshead speed of 1 mm/min at a 45° angle to the long axis of the tooth on the palatal surfaces until tooth fracture occurred. The maximum load and failure mode were recorded. ＜br> RESULTS AND CONCLUSION:Alveolar bone height had a significant influence on the fracture resistance (F=560.943, P>0.05), but fiber post length did not have a significant influence on it (P>0.05). Significant differences were found between the normal and resorbed alveolar bone groups in the number of repairable fracture patterns (χ2=5.689, P＜0.05). Under the circumstance of lowered alveolar bone height, lengthening fiber post cannot enhance fracture resistance of the teeth.
