ABSTRACT
Objective To compare the effects and complications of lumboperitoneal shunt ( LP ) and ventriculoperitoneal shunt ( VP ) in the treatment of post?traumatic hydrocephalus. Methods Eighty patients with post?traumatic hydrocephalus treated in the neurosurgery department of Zhangjiagang Hospital of Traditional Chinese Medicine from March 2014 to March 2010 were retrospectively analyzed. The patients were randomly divided into two groups,40 patients treated with LP were assigned into the LP group and 40 patients undergone VP treatment were seen as the VP group. All patients were followed up for 1 year to investigate and compare the symptom improvement rate,neurological deficit score and the incidence of complication of the two groups. Results The total effective rate of hydrocephalus disappearance in the LP group was 41. 50% ( 37/40) and 87. 50%( 35/40) in the VP group. The difference between the two groups was not statistically significant (χ2=0. 556,P=0. 456);the neurological deficit scores before treatment in the LP group and VP group were (28. 35±8. 64) points and (29. 13±7. 98) points,there was no significant difference between the two groups (t=0. 419,P=0. 676) . The difference in the scores of neurological deficit after treatment in the LP and VP group was not statistically significant ( (19. 32±5. 34) points vs. (21. 62±4. 86) points,t=1. 480,P=0. 143),the average scores of neurological deficits in the two groups were significantly better than those before treatment ( t=5. 623, 5. 084,P0. 05) ,the average score of urinary incontinence improvement after treatment in both groups were better than those before treatment ( t=4. 891,5. 370,P<0. 001) . In the LP group,the incidence of bleeding,infection,shunt related complications and shunt abnormality were all 2. 50% ( 1/40 ) , the overall complication rate was 10. 00%, the incidence of bleeding,infection,shunt related complications and shunt abnormality in the VP group were 7. 50% (3/40), 10% ( 4/40 ) , 5% ( 2/40 ) 10%, ( 4/40 ) , the overall complication rate was 32. 50%, there was significant difference between the two groups (χ2=6. 050,P=0. 014) . Conclusion LP and VP have significant curative effect on the treatment of post?traumatic hydrocephalus,but the overall incidence of LP complication after 1 year is significantly lower than that of VP,and is worth popularizing widely in clinical practice
ABSTRACT
Objective:To explore the clinical characteristics of Haff disease in our hospital,be familiar with the disease and provide some experience in diagnosis and treatment.Methods:Inpatients with Haff disease in our Kidney disease center between July and August 2016 were retrospectively analyzed.The clinical data of patients was collected and statistically analyzed.Results:There were 66 patients (28 of male and 38 of female) in total with Haff disease between July and August 2016 in our ward.The average onset age was 35.5 years old (18-76 years old) and the average latency period was 5.6 hours (1-24 hours).All the patients had crayfish before the onset of the disease.The initial symptoms included muscle pain and concentrated brown urine (19 cases,28.8％).Laboratory tests suggested that transaminase and myotropin were increased significantly (alanine aminotransferase,aspartate aminotransferase,lactate dehydrogenase,creatine kinase,myoglobin and creatine kinase isoenzyme).A trace of blood (45％) and protein (16.7％) was present in some patients' urine test.After treatment,muscle pain was alleviated and urine color turned to clear in all patients.All the transaminase and muscle enzymes were significantly decreased (P＜0.05).No blood or protein was detected in the urine test.Conclusions:The epidemiology of Haffdisease in summer at Nanjing was related to the intake of crayfish.The latency period was short and the initial symptoms were mostly muscle soreness,with or without myoglobinuria.Laboratory tests showed serum creatine phosphokinase,myoglobin,creatine kinase isoenzymes were increased significantly.The treatment period was short with good prognosis.Generally no sequelae was observed.
ABSTRACT
Urate is produced as the major end product of purine metabolism. In the last decade, the incidence of hyperuricemia increased markedly, and similar trends in the epidemiology of metabolic syndrome have been observed. Hyperuricemia is associated with renal disease, and recent studies have reported that mild hyperuricemia results in hypertension, intrarenal vascular disease, and renal injury. This has led to the hypothesis that uric acid may contribute to renal fibrosis and progressive renal disease. Our purpose was to investigate the relationship between uric acid and renal tubular injury. We applied the method of intraperitoneal injection of uric acid to generate the hyperuricemic mouse model. Compared with the saline injection group, the expression of lysyl oxidase (LOX) and fibronectin in kidneys was increased significantly in hyperuricemic groups. In vitro, uric acid significantly induced NRK-52E cells to express the ECM marker fibronectin, as well as LOX, which plays a pivotal role in ECM maturation, in a time- and dose-dependent manner. Upregulation of the urate transporter URAT1, which is located in the apical membrane of proximal tubules, sensitized the uric acid-induced fibronectin and LOX induction, while both knocking down URAT1 expression in tubular epithelial cells by RNA interference and inhibiting URAT1 function pharmacologically attenuated LOX and fibronectin expression. Furthermore, knockdown of LOX expression by a small interfering RNA strategy led to a decrease in fibronectin abundance induced by uric acid treatment. In addition, evidence of a uric acid-induced activation of the NF-kappaB signaling cascade was observed. Our findings highlight a need for carefully reevaluating our previous view on the pathological roles of hyperuricemia in the kidney and nephropathy induced by uric acid in clinical practice.
