1.Renal replacement therapy in pediatric acute kidney injury
Chinese Pediatric Emergency Medicine 2013;20(4):348-351
Acute kidney injury(AKI) is defined as functional and structural disorder or signs of renal damage including any defect from blood and urine test,or tissue imaging that is less than 3 months.The current treatment for AKI includes therapeutic agents and renal replacement therapy (RRT).The goal of RRT is to remove endogenous and exogenous toxins,inflammatory mediator,pathogenic factor,and to maintain fluid,electrolyte,and acid-base balance until renal function returns.The principal methods of RRT include intermittent hemodialysis,continuous renal replacement therapy,peritoneal dialysis,plasmaphresis exchange and hemoperfusion.In this article,we discussed the timing,choice of therapeutic mode,indication and common technical issues of RRT in pediatric AKI.
2.Update on diagnosis and therapy of juvenile myasthenic crisis
Chinese Pediatric Emergency Medicine 2015;22(10):667-671
Myasthenia gravis is an autoimmune disorder resulting from the production of antibodies against acetylcholine receptors leading to the destruction of the postsynaptic membrane at the neuromuscular junction.Myasthenic crisis is defined as any myasthenia gravis exacerbation necessitating mechanical ventila-tion or post-operation extubation delayed beyond 24 hours because of respiratory weakness.Most patients presenting with myasthenic crisis have an identifiable risk factor.The diagnosis of myasthenic crisis should be suspected in all patients with respiratory failure,particularly those with unclear etiology.Acute management of myasthenic crisis includes ventilatory therapy,removal of the offending trigger and immunomodulatory treat-ments.The latter includes plasma exchange or intravenous immunoglobulin,and high dose corticosteroids therapy.

The investigation was conducted among eight untrained male and six well-trained male cyclists with the purpose of finding out the relationship between muscle fiber composition and lactate threshold. Muscle biopsy samples were taken of vastus lateralis to determine the composition of fiber type (Ⅰ, Ⅱ). Maximal oxygen uptake was measured in a progressive cycle ergometer test, while blood lactate threshold was determined on the basis of a systematic increase in BLa above baseline warm-up values. Analyses show that the percentage of type Ⅰ is closely correlated with lactate threshold in both groups of subjects and that muscle fiber composition plays (?) important role in determining lactate threshold. Therefore, an assessment of muscle fiber composition is useful for spotting athletes with high potential for endurance performance.

Objective:To investigate the expressions of matrix metalloproteinase 9 (MMP-9), matrix metalloproteinase 2 (MMP-2), migration-inducing protein 7 (MIG-7) and filamin A (FLNa) in colon cancer tissues and their effects on prognosis.Methods:The tumor specimens and corresponding adjacent normal tissues of 899 colon cancer patients undergoing surgical resection in the Affiliated Huai'an No. 1 People's Hospital of Nanjing Medical University from January 2013 to December 2015 were collected. The expression levels of MMP-9, MMP-2, MIG-7 and FLNa in colon cancer tissues and adjacent normal tissues were measured by using enzyme-linked immunosorbent assay (ELISA), and the relationship between their expression levels and clinicopathological characteristics as well as prognosis of colon cancer was analyzed.Results:The expression levels of MMP-2, MMP-9 and MIG-7 in colon cancer tissues were (481±69) ng/ml, (262±85) ng/ml,(156±23) ng/ml, respectively, which were higher than those in adjacent normal tissues [(136±33) ng/ml, (191±21) ng/ml, (98±18) ng/ml], and the differences were statistically significant ( t was 41.591, 120.224, 59.896, all P < 0.01); the expression level of FLNa in colon cancer tissues was (19.5±3.2) ng/ml, which was lower than that in adjacent normal tissues [(65.4±8.3) ng/ml], and the difference was statistically significant ( t = 154.902, P < 0.05). The expression levels of MMP-9, MMP-2, MIG-7 and FLNa in colon cancer tissues were correlated with tumor diameter, Dukes stage, lymph node metastasis and degree of differentiation (all P < 0.05). Cox multivariate analysis showed that the high expressions of MMP-9, MMP-2, and MIG-7 and the low expression of FLNa were independent factors affecting the prognosis of patients (all P < 0.05). Kaplan-Meier analysis showed that the median overall survival time of patients with low expression of MMP-9, MMP-2 and MIG-7 was 55 months (95% CI 25-78 months), 56 months (95% CI 26-79 months) and 54 months (95% CI 25-78 months), respectively, which were longer than those with high expression, while the median overall survival time of patients with high expression of FLNa was 58 months (95% CI 27-80 months), which was longer than those with low expression, and the difference was statistically significant ( P < 0.05). Conclusions:MMP-9, MMP-2, MIG-7 and FLNa are closely related to the occurrence and progression of colon cancer. The high expression levels of MMP-9, MMP-2 and MIG-7 and the low expression level of FLNa have influences on the prognosis of colon cancer patients, and it can be used as important indicators for clinical prognosis judgement.
