Objectives To investigate the practical application of modified peritoneal equilibration test (modified PET) employing 4.25% glucose exchange in peritoneal dialysis patients and to assess the reference values and clinical significance of the test. Methods Modified PETs were performed in 97 patients without peritonitis for at least 4 weeks. Mass transfer area coefficient (MTAC) was calculated according to the Garred model. Creatinine D/P concentration ratio at 4 hr (4 h D/Pcr), sodium D/P concentration ratio at 1 hr (1 h D/PNa+) and net ultrafiltration (nUF) were also assessed. Ultrafiltration 0.05). 4 h D/Pcr and MTACcr of modified PET were significantly correlated with 4h D/Pcr of standard PET (P

Objective To investigate the risk factors, diagnostic evaluation, etiology, and treatment in young patients with ischemic stroke. Methods The clinical data of young patients (age range 18 - 45 years) with ischemic stroke (within 2 weeks of stroke onset) admitted to the Stroke Center, the First Affiliated Hospital of Sun Yat-sen University from August 2008 to July 2013 were registered prospectively. Results A total of 300 patients were enroled, their age was 37. 8 ± 6. 8 years. There were 227 males (75. 7% ). The age of 84 patients (28. 0% ) was ≤35 years. The most common risk factors were smoking (43. 3% ), hypertension (38. 7% ), and hypercholesterolemia (38. 0% ). The positive result detection rates were lower in the antinuclear antibody (8/278), anticardiolipin antibody (34/250), 24-h Holter monitoring (2/60 ), and transthoracic echocardiography (38/232). According to the MRI findings, the detection rate of the white matter changes, old infarcts, single acute infarcts, and multiple acute cerebral infarcts were 40/282, 77/282, 145/282, and 137/282, respectively. The stroke subtypes of TOAST: large artery atherosclerosis (26. 7% ), smal artery occlusion (18. 0% ), cardioembolism (10. 0% ), other determined etiology (23. 0% ), and undetermined etiology (22. 3% ). Large artery atherosclerosis was mainly involved in anterior circulation (69/80) and intracranial arteries (75/80). In other definite causes, cerebral artery dissection was most common (36/69), and other causes included moyamoya disease (7/69) and infectious vasculitis (7/69), etc. The average length of hospital stay was 15. 4 d. The mean National Institutes of Health Stroke Scale score on admission was 7. 0, and the mean modified Rankin scale score at discharge was 2. 5. The complication rate during hospitalization was 9. 7% . 80. 3% and 48. 3% of patients received anti-platelet drugs and statins therapy during hospitalization.Conclusions This study used a prospective single-center method. It conducted a comprehensive analysis of risk factors, diagnostic evaluation, treatment, and etiology in current Chinese young patients with ischemic stroke. Its research data wil provide useful information for establishing a diagnostic strategy of high performance cost ratio, in-depth understanding of its pathophysiological mechanisms, and improving treatment strategies in Chinese young patients with ischemic stroke.

Objective To investigate the values of conventional magnetic resonance imaging (MRI),magnetic resonance angiography (MRA),and high-resolution MRI for diagnosing intracranial arterial dissection (IAD)caused ischemic stroke. Methods From August 2008 to April 2015,59 consecu-tive patients (age 45 ±15years,41males)with IAD caused ischemic stroke admitted to the First Affiliated Hos-pital of Sun Yat-Sen University were enrolled prospectively. All patients underwent conventional cranial MRI/MRA examination,25 of them underwent whole brain DSA examination,and 10 underwent high-resolution MRI. The findings of conventional MRI/ MRA and high-resolution MRI of IAD were analyzed. For patients undergoing DSA,the proportions of detection and compliance of IAD were compared between DSA and conventional MRI / MRA. Results (1)Conventional MRI / MRA revealed typical sign of artery dissection in 42 patients (71. 2%),among them,the intramural hematoma (n = 22,52. 4%)was most common. Other common signs included intimal flap/ double lumen sign (n = 13,31. 0%)and long irregular or thread-like stenosis (n = 9,21. 4%);while dissecting aneurysm (n = 7,16. 7%)and rat tail-shaped occlusion (n = 3, 7. 1%)were relatively rare. In 17 patients (28. 8%)with IAD that conventional MRI/ MRA did not detect the typical dissection sign,the dissections were involved in the middle cerebral artery (11 / 17,64. 7%), they were more common than the 42 patients with IAD (10 / 42,23. 8%)detected the typical dissection sign by conventional MRI/ MRA. There was significant difference (P = 0. 006). (2)Among the 25 patients undergoing DSA,DSA revealed that 15 patients (60%)had the typical dissection sign,and conventional MRI/ MRA only revealed 8 of them (32%)with the typical dissection sign,but there was no significant difference (P = 0. 088). In 15 patients with IAD that DSA detected the typical dissection sign;conventional MRI / MRA detected the typical dissection sign in 8 of them. The diagnostic coincidence rate was 8 / 15. (3)Both conventional MRI/ MRA and DSA revealed non-specific limitation stenosis or cut-off occlusion in 10 patients (16. 9%)with IAD,while the high-resolution MRI revealed intimal flap in 5 of them,intramural hematoma in 4,and intimal flap and intramural hematoma in 1. Conclusion Conventional cranial MRI/MRA is an effective technique for revealing IAD,whereas high-resolution MRI has the unique advantages for diagnosing IAD without typical dissection in other vascular imaging.

Objective Toinvestigatetheriskoflong-termrecurrenceofstrokeanditspredictorsin youngpatientswithischemicstroke/transientischemicattack(TIA).Methods Theclinicaldataofthe consecutive young patients (18-45 years)with ischemic stroke/TIA (within 2 weeks after onset)admitted to the department of neurology in the First Affiliated Hospital of Sun Yat-Sen University between August 2008 and July 2013 were enrolled prospectively. All patients were regularly followed up for a long time (The patients were followed up at the 1 st,6 th,and 12 th month after onset;then they were followed up once for every 6 months)in order to investigate stroke recurrence. The Kaplan-Meier curves were used to analyze the cumulative stroke recurrence rate of all patients. The last contact time for patients lost to follow was used as censored data to be enrolled in the analysis. The univariate analysis of the related risk factors for stroke recurrence using Log-rank test. Multivariate Cox proportional hazard regression was used to detect the related risk factors associated with stroke recurrence (adjusting for age and sex). The variables of the results of Log-ranktestP≤0.1wasselectedandenrolledinthemultivariateregressionanalysis.Results Atotalof 312 patients were enrolled in the analysis,including 294 with ischemic stroke and 18 with TIA. Their mean follow-up time was 34 ± 19 months. Thirty-four patients had recurrent stroke,including 23 with ischemic stroke,7 with TIA,and 4 with cerebral hemorrhage. The cumulative recurrence rates of stroke at 1 ,3 , and 6 years after onset were 6. 2%,10. 3%,and 16. 4%,respectively. The results of multivariate Cox proportional hazards regression analysis showed that hypertension (risk ratio [RR]2. 159;95% confidence interval [CI]1. 048-4. 447,P=0. 037)and cardioembolism (RR,2. 869;95%CI 1. 119-7. 357,P=0.028)weretheindependentpredictorsforstrokerecurrence.Conclusion Theoverall6-yearriskof recurrent stroke is not high in the Chinese young patients with ischemic stroke/TIA,but the risk of stroke recurrence is relatively higher in the first year. Hypertension and cardioembolism are the potential predictors of stroke recurrence;therefore,attention should be paid in clinical practice.

Objective:The feasibility of a minimally invasive cosmetic transbilical laparotomy was studied in fifty-seven pediatric patients.The advantages of this technique will be discussed.Methods:The circumferential incision was made following the ring fold of the right umblilicus,which was less than 2700.The peritoneum was opened in the midline via rectus abdominis.Intra-peritoneal lesions were detected and explored.The surgical procedures were able to be carried out either inside or outside of the peritoneum.After closure of peritoneum,the umbilical incision was closed subcutaneously with an absorbable suture.Results:From January 2001 to January 2005,58 procedures via transumbilical route have been done in 57 pediatric patients.None of those cases required conversion to a traditional abdominal incision.The duration of surgery was from 20 to 170 minutes.All patients were discharged five days postoperatively and follow-up was conducted from 3 months to 4 years.No complications were observed in all but one patient.This patient had a leaking anastamosis.No visible scars were present and the cosmetic results were excellent.All patients had shorter hospital stay and lower operating cost.Conclusion:Transumbilical approach is a feasible,safe,economical,minimally invasive procedure with excellent cosmetic results which appears to be superior to traditional procedures.It suggests that the transumbilical route should be widely used clinically and might be applicable for elder children and possibly would be of benefit in the treatment of other conditions.

Objective To compare the outcomes of patients starting peritoneal dialysis (PD)within two weeks and more than two weeks after catheter implantation.Methods All the patients undergoing Tenckhoff catheter implantation and initiating PD in Renji Hospital from January 2001 to December 2010 were enrolled in the study.Patients started PD within 2 weeks after catheter insertion were defined as urgent group,and those started PD 2 weeks later were defined as planned group.Kaplan-Meier curves and Log-rank tests were used to compare outcomes between two groups.Results Among 657 patients in this study,median break-in period was 6 days of 469 (71.4％)patients in urgent group and 26 days of 188 (28.6％) patients in planned group.Compared to planned group,patients of urgent group were younger [(52.6± 17.3) vs (56.1± 15.3) year,P =0.017],had less eGFR [(5.36±2.03) vs (6.50±2.50) ml· min-1 · (1.73 m2)-1,P ＜ 0.01],lower serum albumin [(34.0±5.7) vs (36.2±5.9) g/L,P ＜ 0.01] and hemoglobin [(76.9± 18.8) vs (80.8 ± 17.9) g/L,P =0.018],and higher phosphate [(2.19±0.67) vs (1.98±0.52) mmol/L,P＜ 0.01].Urgent group presented more catheter dysfunctions needed to transfer to hemodialysis (2.1％ vs 0％,P =0.044).The 1-,2-,3-and 5-year technique survival rates of urgent and planned group were 94％ vs 98％,92％ vs 94％,90％ vs 92％and 86％ vs 85％ respectively.There was no significant difference in technique survival (Log-rank =1.536,P =0.22) and peritonitis-free survival (Log-rank =0.035,P =0.85) between two groups.The 1-,2-,3-and 5-year patient survival rates of urgent and planned group were 90％ vs 95％,81％ vs 90％,74％ vs 79％ and 67％ vs 74％ respectively,and no significant difference was found (Log-rank =2.364,P =0.12).Conclusions Although patients needing urgent initial PD have poorer residual renal function and nutritional condition compared to those of planned initial PD,their outcomes are similar.Peritoneal dialysis may be a feasible and safe dialysis modality for patients who need urgent start.
