Objective To study the value of the changes of signal intensity at the jugular bulb in diagnosing sigmoid sinus thrombosis.Methods MR imaging examinations were performed in 27 cases with cerebral venous sinus thrombosis(transverse and sigmoid sinuses).The signal intensity at the jugular bulb was evaluated in comparison with that in 20 healthy persons,and the results were dealed with Wilcoxon rank sum test statistically.Results In sigmoid sinus thrombosis,the signal intensity at ipsilateral jugular bulb was higher than that in healthy group(P

Objective To explore the clinical meanings of serum CA19-9 levd in hepatocirrhosis patients. Methods 61 hepatitis B and hepatocirrhosis patients were as treatment group, and 35 normal were as control group. The content of serum CA19-9 was measured by dectrochemistry lighting and the liver function was determined too. According to Child-Pugh liver function integral method,the treatment group was divided into 27 cases of A grade,20 cases of B grade and 14 cases of C grade. Results The serum CA19-9 level in hepatocirrhosis patients was higher than that of normal group significantly(P< 0. 005 ). The serum CA19-9 level decreaed obviously through the treat- ment,thereinto A and B grade fell evidendy in the Child-Pugh liver function integral method( P < 0. 005). C grade was not significantly different(P<0.05 ). The serum CA19-9 levd was positivdy associated with TBiL, ALT and AST of liver function integral method. Conclusion The serum CA19-9 levd of hepatocirrhosis patients is improved in different degrees. And it can be a prognostic target and used to estimate the degree of damage of liver function of hepatocirrhosis patients.

Objective To investigate the endovascular treatment of peripheral vascular anomaly in children and its efficacy.Methods Eighty-three children with peripheral vascular anomaly were treated via endovascular means. Before and during the endovascular operation,all the cases were diagnosed as follows: arteriovenous fistula in 23 cases, cirsoid angioma 32 and cavernous hemangioma 28. The endovascular approaches included:①transcatheter embolization using coils or gelfoam sponge;② transcatheter embolization combined with local cirrhosis agents treatment.Results Immediate angiography after embolization showed all the arteriovenous fistulas and hemangiomas were efficiently occluded and the clinical presentation and symptoms improved greatly. Follow-up one to three years after operation demonstrated 100% of efficacy and 68.7% curative rate with no complications. Conclusions Endovascular approach for peripheral vascular anomaly in children is a micro-invasive, safe and effective way.

Objective:To investigate the significance of regulatory T cells in peripheral blood of chronic renal insufficientce.Methods:The peripheral blood samples were collected from 40 patients with chronic renal insufficient.The ratios ot CD4+T cell in lymphocyte and CD4+CD127-Treg and CD4+CD25+CD127-Treg in CD4+T were detected by flow cytometry.Results:The number of CD4+T in lymphocyte of chronic renal insufficient was higher than in healthy control group and there wasn’t significantly difference of the CD4+CD25+CD127-Treg ratios in CD4+T between chronic renal insufficience and healthy central.The ratio of CD4+T cells in lymphocytes of chronic renal insufficience was lower than in healthy control group except compensatory stage.There was no correlation between CD4+T cell ratios in lymphocytes,CD4+CD127-Treg or CD4+CD25+CD127-Treg ratios in CD4+T cells and the values of BUN,Cr among the hypertension patients.Conclusion:The number of CD4+T cells increases,and CD4+CD127-Treg decreases in the patients with chronic renal insufficience and their immune functions are shown in disoroler .

Objective To detect the change of discharge phase of guinea pig hippocampal CA1 pyramidal cells during visual discriminative task with an effective and convenient program we designed. Methods Five guinea pigs were performed by extracellular single unit recording in vivo when they were performing visual discriminative task. Discharge signals of individual pyramidal cells were extracted from different frequency signals by wavelet transform (WT), which made it feasible to calculate discharge phase of pyramidal cells in terms of time correlation between discharge and ? rhythm. Results The discharge phase of CA1 pyramidal cells in the 1 to 5s interval before visual discriminative task (172??1.8?) was obviously earlier than that in the 6 to 10s interval after visual discriminative task (189??3.7?) ( P0.01). Conclusion The program we designed is capable of detecting discharge phase of pyramidal cells. Regular shift of discharge phase of hippocampal CA1 pyramidal cells emerges before and after performing visual discriminative task.

Objective To study the relationship between microalbuminuria and inflammation media of C-reactive protein(CRP) and interleukin-6(IL-6) in type 2 diabetes mellitus,and to explore the clinical significance.(Methods)Ninety-six patients with type 2 diabetes mellitus were divided into 3 groups according to the urine albumin excretion rate(UAER): normal albuminuria group(NA),microalbuminuria group(MA) and clinical proteinuria group(CP).The serum levels of CRP,IL-6,fasting plasma glucose,creatinine and fasting insulin were measured in all the cases. Results The levels of CRP and IL-6 in MA group were significantly higher than those in NA group(P

Objective To explore the feasibility of using the modified continuous balloon dilatation substituting the traditional membrane-covered stent in the treatment of benign esophageal stenosis in children.Methods A retrospective analysis of the clinical data of 25 cases with esophageal stenosis from January,2012 to February,2014 was conducted.Preoperative esophageal stenosis was confirmed by angiography,and the expansion of the stenosis segment was examined after 2-4 weeks postoperatively.According to the age and the location of the esophageal stricture,25 cases were classified into two groups.Twelve cases of group A without obvious contraindications were treated by continuous balloon dilatation,while 13 cases of group B with age of less than 3 years or upper esophageal stenosis,retrievable stent implantation was performed.All cases were followed up from 6 months to 2 years.Clinical symptoms,swallowing fluency and the degree of esophageal stricture were followed up at 1,3,and 6 months postoperatively,and the effect of treatment was evaluated.Results Two groups of patients were successfully treated,and the stents were removed successfully after 2-4 weeks.The average diameter of the stenosiswas significantly increased after treatment,swallowing was improved obviously,with no perforation,hematemesis and melena and other serious complications.The balloon moved down happened in one case,which was adjusted under perspective observation.One case in group A underwent colonic interposition for esophageal replacement because of recurrence of restenosis.The balloon dilatation was effective in 10 cases.In Group B,5 patients had stent migration or displacement,3 cases had recurrent esophageal stricture,and the treatment was effective in 5 cases.There was significant difference in complications between the group A and B (x2=5.23,P＜0.05).Conelusions Continuous balloon dilatation is a simple,effective procedure with fewer complications in the treatment of children with benign esophageal stenosis.In addition to stenting,it may be another ideal choice for benign esophageal stenosis in children.

Objective To analyze the relationship between the levels of plasma total homocysteine (Hcy) and umbilical arterial with color doppler ultrasound with the severity of preeclampsia(PE).Methods A total of 70 cases of the third trimester of normal pregnancy, 72 cases of mild PE, and 66 cases of severe PE were selected.Then plasma Hcy levels and umbilical arterial with color doppler ultrasound were detected.Results Hcy levels were statistically significant difference among the normal control group,mild PE group,and severe PE group((8.950±0.585), (11.116±0.615), (14.648±0.620) μmol/L,P＜0.05).Umbilical artery blood flow parameter S/D values in severe PE group was significantly higher in mild PE group and in contrg.1 group (3.43 ±0.72 vs.2.86 ± 0.82 vs 2.75 ± 0.56, P＜ 0.05), while the control group, mild PE group had no significant difference(P＞0.05).Resistance index(RI) ,Pulsatility index(PI) in mild PE group and severe PE group were significantly higher than control group(0.60±0.05,0.78±0.07 vs.0.57±0.06;1.24±0.21,1.47±0.64 vs.0.67±0.35), and the differences among three groups were significant(P＜0.05), while the mild PE, severe PE group had no significant difference(P＞0.05).Hcy of mild PE group was positively correlated with S/D, RI and PI(r=0.548,P=0.009;r=0.587,P=0.008;r=0.324,P=0.02).Hcy of severe PE group was positively correlated with S/D,RI and PI(r=0.752,P=0.001;r=0.627,P=0.003;r =0.438,P=0.024).Hcy and the severity of PE was positively correlated (r =0.450, P ＜ 0.05), S/D and the severity of PE was positively correlated(r=0.316, P =0.002).RI, PI and the severity of PE was no correlation (r =0.024, P =0.726;r =0.054,P =0.649).Conclusion The levels of Hcy and S/D were related to the severity of PE.To reduce Hcy,and monitor S/D were new ways for the diagnosis and treatment of pre-eclampsia.

Objective To explore risk factors,prevention and treatment of common complications of benign esophageal stenosis treated with the retrievable covered stents in children.Methods Fifteen cases,diagnosed as benign esophageal stenosis by barium esophagogram were treated with retrievable covered stents under fluoroscopy,Then the stents were removed after 2-3 weeks.The cases were followed-up and complications were observed.Results The stents were successful implanted in all cases.The diet was improved obviously after operation,and gradually transformed from liquid,semiliquid to normal feeding.At the same time,narrow section gradually expanded from 0.1-0.6 cm to 0.6-1.5 cm.Postoperative follow-up was in 1,2,3 weeks and 3 months.Main complications were stents shift in 5 cases,esophageal restenosis in 2 cases,esophageal-tracheal fistula in 1 case,postoperative dull pain behind sternum and foreign body sensation in 6 cases.Relevant preventions and treatments were performed based on different complications.Conclusion It should not be ignored that complications after covered stent placement are more in children than in adults,preventions and treatments should be taken positively.
