Objective: To discuss the management principles and skills for treatment of intractable ureterostenosis under ureteroscope. Methods: Our management experience on 19 patients with intractable ureteral stenosis was retrospectively analyzed. The 19 cases included urological TB-caused multiple ureteral stenosis, oncothlipsis to ureters from intestinal tract or gynecology, restenosis 3 months to 12 years after pelviureteric junction plasty, operative site stenosis after ureterolithotomy, double ureter back flow accompanied by stenosis, ureter imperforation after renal parenchyma lithotomy without placing double "J", ureter imperforation 3 months after extracorporeal shock-wave lithotripsy due to ureterolith, tubal bladder stoma stenosis after renal transplantation, restenosis after tubal bladder stoma due to distal ureterostenosis, and so on. All the patients were treated under ureteroscope. The management methods included: the Wolf 8/9. 8 CH12° and Wolf 6/7. 6 CH5° ureteroscope was used as a dilator to dilate the stenoses; balloon expanding under ureteroscope was used to dilate the stenoses; the ureter pliers was used to expand the stenoses to different directions; the cold knife was used to open the stenoses; if the diameter of stenoses were smaller than the that of the ureteroscopes, F4. 5 or F3 double "J" tubes were inserted guided by a wire under ureteroscope; and 2 or 3 weeks later, a larger tube or two tubes were introduced into the stenoses already dilated partly by the former tube. Results: Ureteroscopic method failed in treating 2 patients in our group and succeeded in treating all the other patients. The outcomes of patient were fine during 2 months to 3 years' follow-up. Conclusion: It is difficult to treat patients with intractable ureterostenoses. With good experience in manipulation of ureteroscope, the flexible application of several techniques according to the different conditions of different patients can guarantee successful treatment in most patients.

ObjectiveTo explore the influence of peritoneal transport characteristics on the nutritional status of patients with continuous ambulatory peritoneal dialysis(CAPD).MethodsSeventy-three CAPD patients were involved in this cross-sectional study.According to the results of peritoneal equilibration test(PET),the patients were divided into high transport group with 43 cases and low transport group with 30 cases.Nutritional status was evaluated with the subjective global assessment (SGA) score and the differences were analyzed between two groups in the albumin (ALB),total protein (TP),hemoglobin (Hb),primary disease,age,weight,dialysis time,ultrafiltration,blood urea nitrogen ( BUN ),serum creatinine (SCr) and so on.Results There was no difference between two groups in age,weight,ultrafiltration,systolic blood pressure,diastolic blood pressure,Hb,SGA score,BUN and SCr (P＞0.05).However,the dialysis time,the case number of diabetic nephropathy (DN) as original disease,the case number of non DN as original disease,TP and ALB between high transport group and low transport group had significant differences [(14.35±13.88) months vs.(24.20 ±19.62) months,16 cases vs.12 cases,27 cases vs.18 cases,( 64.98±7.59 ) g/L vs.( 68.73 ± 6.96 ) g/L,( 34.61 ± 5.43) g/L vs.( 38.71±3.82 ) g/L,P ＜ 0.05 ].Conclusions The nutritional status of CAPD patients with different transport characteristics have significant differences.CAPD patients with high transport characteristics are complicated with worse nutritional status,compared with those patients with low transport characteristics.

ObjectiveTo evaluate the effect of radical proctectomy with TME for the treatment of rectal carcinoma in the prevention of postoperative local recurrence. Method78 patients undergoing this procedure were followed up for 5 years.ResultLocal recurrence developed in 10 cases during 5 year′s follow up, with recurrence related mortality of 7/78, local recurrence rate of 10/78 (13%). Tumor malignancy and Dukes′ grade were in direct proportion with the recurrence. The 5 year′s survival rate was 88%(69/78). The postoperative 5 year′s survival rate in Dukes′ A, B and C patients was respectively 100%(9/9), 92%(51/54), and 64%(9/14). ConclusionRadical proctectomy with TME is superior to that without TME in terms of low postoperative local recurrence rate for the treatment of rectal carcinoma.

Objective To explore a surgical therapy on close depressed fracture of the skull.Methods Ni-Ti form memory-alloy cramps were fixed on between the depressed bone and the normal surrounding skull in 16 patients with close depressed fracture of the skull.Results The follow up was 5～54 months(average 26 months).It indicated that there was no displacement and depressing of the fixed bone, no subcutaneous collection of fluid, no reject reaction and inflammation, and no erosion. The fixed bone and skull density showed normal by X ray and the fixed cramp did not disturb CT and MR scaning. All patients declared no mental burden and felt safe.Conclusion The Ni-Ti form memory-alloy cramp has a good mechanical restoration force and a good plastic effect,but no complication,it can increase the ability to resist external force in fracture region, and the surgical procedure is very simple, therefore it is ideal to treat the depressed fracture of skull.

Objective To observe the clinical efficacy of auricular point sticking plus basic nursing for constipation of excessive syndrome in acute stage of stroke.Method Ninety patients with constipation of excessive syndrome in acute stage of stroke were randomized into a treatment group and a control group, 45 cases in each group. The treatment group was intervened by auricular point sticking plus basic nursing, while the control group was by basic nursing alone. The major symptom scores were observed before intervention and after 2-treatment courses, and the clinical efficacies were compared between the two groups.Result Respectively after 1 and 2 treatment courses, there were significant differences in comparing the major symptom scores between the two groups (P<0.05). The total effective rates were respectively 60.0% and 67.5% in the treatment group respectively after 1 and 2 treatment courses, versus 37.5% and 45.0% in the control group, and the differences were statistically significant (P<0.05). Conclusion Auricular point sticking is an effective approach in treating constipation of excessive syndrome in acute stage of stroke.

Objective:To study the behavior problems in children with Tourette syndrome and related family factors.Methods:132 children with Tourette syndrome were collected as our sample. Their parents completed CBCL (child behavior checklist) and FES (family environment scale).Results:The rate of behavior problems in this group was 26.5%, much higher than that of normal children (13.6%). The main factors having influence on this included expressiveness, independence and initiative, entertainment and moral religion. The Wald of the four factors in Logistic regression were 13.73, 10.35, 7.97 and 5.62(P

Objective To investigate the changes of ubiquitin C-terminal hydrolase-L1 (UCH-L1) and glial fibrillary acidic protein (GFAP)in acute phase of cerebral infarction. Methods From March 2011 to June 2012,95 patients with early cerebral infarction from the Neurology Clinic,the Emergency Department and the Cerebral Apoplexy Screening Project Base,and the Neurology Ward of Renhe Hospital were used as an infarction group;61 non-stroke subjects received physical examination in the Physical Examination Center of our hospital in the same period were used as a control group. The cerebral infarction group and the patients with cerebral infarction in different onset of time groups (an onset < 12 h group and an onset 12-24 h group),the different National Institutes of Health Stroke Scale (NIHSS)score groups (NIHSS 0 -4 group and NIHSS 5 -19 group),and the levels of UCH-L1 and GFAP in the control group were measured and compared among the groups. The receiver operating characteristic (ROC)curve was established. The cut-off values of the relevant parameters in the diagnosis of cerebral infarction,and the sensitivity and specificity of diagnosis were obtained. Results The UCH-L1 and GFAP values of the cerebral infarction group were all higher than those of the normal control group (0. 13[0. 09,0. 21]μg/ L vs. 0. 05[0. 02,0. 13]μg/ L,0. 030[0. 008,0. 130]μg/ L vs. 0. 004[0. 004,0. 020]μg/ L,Z values were 3. 62 and 4. 95 respectively;all P < 0. 01). The UCH-L1 and GFAP values of the NIHSS score 5 -19 group were higher than those of the NIHSS score 0 -4 group (0. 12[0. 08,0. 21]vs. 0. 09[0. 08,0. 18],0. 07 [0. 01,0. 11]vs. 0. 04[0. 01,0. 10];all P < 0. 05). There was no significant difference in the UCH-L1 and GFAP values between the onset 12 -24 h group and the onset < 12 h group (0. 12[0. 08,0. 21]μg/ L vs. 0. 09[0. 08,0. 18]μg/ L,0. 030[0. 010,0. 110]μg/ L vs. 0. 040[0. 008,0. 100]μg/ L;all P > 0. 05). The analysis results of ROC curve of UCH-L1 and GFAP for diagnosis of acute cerebral infarction showed that when the plasma UCH-L1 was ≥0. 18 μg/ L,the sensitivity and specificity of UCH-L1 were 68% and 74%respectively;When the plasma GFAP was ≥0. 11 μg/ L,the sensitivity and specificity of GFAP were 70% and 86% respectively. The area under the ROC curve of UCH-L1 and GFAP diagnosis of cerebral infarction were 0. 64 and 0. 71 respectively. Conclusions UCH-L1 and GFAP have obvious change in acute phase of cerebral infarction. UCH-L1 and GFAP may have certain correlation with the severity of stroke.

AIM: To evaluate the effect of carbon monoxide(CO) on the permeability of brain blood barrier(BBB) in cerebral ischemic rats. METHODS: SD rats were divided into three groups. Saline, hemin or ZnPP were injected intraperitoneally 12 h before middle cerebral artery occlusion (MCAO), respectively. The concentration of blood CO and the permeability of BBB at 24 h after MCAO were measured. RESULTS: The CO concentration in blood in hemin group was higher than that in saline group( P 0.05). CONCLUSION: CO reduced the permeability of BBB as a messenger gas molecular when its intrinsic concentration was elevated.
