Objective To evaluate the curative effect of valproate and levetiracetam in children with epilepsy.Methods32 patients in the first people's hospital of Xiaoshan district from March 2015 to November 2016 application of levetiracetam in treatment of children with epilepsy as the study group, another year over the same period in 35 cases of infantile epilepsy in children in our hospital using sodium valproate treatment as the observation group, two groups of children with different drugs in the treatment of the obtained to compare therapeutic effect.ResultsCompared with the control group (71.9%), the effective rate of the treatment group was significantly higher than that of the control group (P<0.05), and the effective rate was 85.7%.ConclusionSodium valproate is an ideal drug for the treatment of epilepsy in children, the two drugs have a certain anti epileptic effect, but compared to the effect of sodium valproate in the treatment of clinical advantages.

Objective To investigate the effect of artorvastatin on macrophage accumulation in tubulointerstitium of unilateral ureteral obstructive (UUO) nephropathy and its possible mechanism.Methods Twenty-one rats were randomly divided into three groups: sham-operatipn, UUO, UUO+ artorvastatin. Immunohistochemistry staining of CD68 and M-CSF was used to define the macrophage accumulation and expression of interstitial M-CSF. Lipid profile in these groups was also determined. Results CD68 + cells and M-CSF expression were significantly increased at day 10 after UUO operation, this kind of CD68 + cell accumulation and M-CSF expression up-regulation were ameliorated by artorvastatin treatment. In UUO and atorvastatin treated groups, the number of macrophage was positively correlated with tubulointerstitial M-CSF expression. There was no significant difference about serum lipid among the three groups. Conclusion Atorvastatin can reduce interstitial macrophage accumulation in UUO nephropathy. This therapeutic effect might relate to down-regulation of tubulointerstitial M-CSF expression.

Objective To compare the curative effect of magnesium isoglycyrrhizinate and compound ammonium glycyrrhetate in patients with liver cirrhosis of decompensated.Methods Eighty-six patients with liver cirrhosis of decompensated were enrolled into the study and randomly divided into two groups: the treatment group(n=43) were given magnesium isoglycyrrhizinate once a day in addition to routine treatment;the control group(n=43) were given compound ammonium glycyrrhetate once a day in addition to routine treatment.The clinical manifestation,including symptoms,signs and hepatic function were observed.The clinical lab data,including blood routine examination,urine routine test and kidney function of all patients from two groups were collected before and after the treatments.The adverse drug reactions were monitored throughout the whole therapy.Results ALT and AST turned to normal in 97.7%(42/43) and 90.7%(39/43) of patients respectively in the treatment group,which were significantly higher than those of 72.1%(31/43) and 74.4%(32/43) respectively in the control group( x2=9.86 and 4.73,respectively,Ps＜0.05). Time to turning to normal in ALT and AST were(21.6±9.1)d and(23.1±10.6)d in the treatment group,which were significantly lower than those of(37.5±17.8)d,and(46.7±19.4)d respectively in the control group(t=5.23 and 7.01,respectively,Ps＜0.01).Conclusion The results suggested that magnesium isoglycyrrhizinate had better effect on alleviating symptoms and decreasing enzyme in treatment of liver cirrhosis of decompensated stage.

Objective To characterize the expression of surfactant protein A (SP-A) in normal and acute pyelonephritic rat kidneys and to study the correlation of infection and inflammation with SP-A expression. Methods Twenty-one rats were randomly assigned into three groups: control, sham operation and pyelonephritic group. HE staining was used to determine tubulointerstitial inflammation. Reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blotting were used to determine the mRNA expression and protein level of SP-A. Immunohistochemical staining was used to label the localization and intensity of SP-A expression in kidney tissue. The correlation between intensity of SP-A expression and interstitial inflammation was also evaluated. Results In pyelonephritic group, tubulointerstitial inflammation was more prominent than that in control and sham groups (54.3?11.5,6.4?1.4, 8.6?1.9,respectively). RT-PCR and Western blotting revealed that SP-A expression was up-regulated in pyelonephritic group (in mRNA level: 2.2+0.58, 0.9?0.25, 1.1? 0.30; in protein level: 0.45?0.09, 0.24?0.05, 0.26?0.05, respectively). Immunohistochemical staining demonstrated that SP-A expression was mainly localized on epithelial cells in outer medullary and collecting tubules in normal group and sham group, but strong staining extended to collecting tubules in pyelonephritic group. The tubulointerstitial inflammation score was positively correlated with the intensity of SP-A expression (r=0.67,P

Objective To investigate the effect of surfactant protein A (SP-A) on the production of MIP-2 and binding activity of NF-?B in rat tubular epithelial cells, and evaluate its possible role in renal inflammation. Methods Confluent cultures of NRK-52E cells (a renal tubular epithelial cell line of rat origin) were pretreated with various concentrations of SP-A(0 to 80 ?g/ml) and stimulated by lipopolysaccharide (LPS) (10 ?g/ml) with 2% serum. MIP-2 expression was measured by enzyme-linked immunosorbent assay (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR). The effect of SP-A on NF-?B binding activity was assessed by electrophoretic mobility shift assay (EMSA). Results MIP-2 mRNA and protein was expressed and up-regulated in NRK-52E cells stimulated by LPS. The expression of MIP-2 was down-regulated by SP-A. NF-?B binding activity was inhibited by SP-A in a concentration-dependent manner. Conclusion SP-A binding activity and down-regulates the expression of MIP-2 in renal tubular epithelial cells, which may play an important role in the modulation of renal tissue inflammation.

Objective To investigate the clinical and pathological characteristics of renal involvement in Beh(c)et's disease (BD).Methods A retrospective analysis was carried out in BD patients complicated with renal damage who were admitted to Peking Union Medical College Hospital from June 1998 to July 2012.Results Twenty patients with renal involvement constituted 3.2％ of all the 618 hospitalized BD patients.The presentation of renal disease was chronic glomerulonephritis in 6 patients (1 with nephrotic syndrome),renal tubular acidosis in 1 patient,renal artery stenosis in 7 patients,renal vein thrombosis in 1 patient,and chronic renal failure of unknown etiology in 5 patients.Kidney biopsy was performed in 5 patients,3 of them revealed glomerular minor lesion,mild mesangial proliferative glomerulonephritis and chronic tubularinterstitial nephropathy,respectively.The other 2 patients underwent a second biopsy,one with glomerular minor lesion transforming into IgA nephropathy of grade Ⅲ on Lee's glomerular grading system after 6 years,and the other with IgA nephropathy of grade Ⅱ progressing to grade Ⅳ after 2 years.After the diagnosis of renal BD,one patient with uremia underwent peritoneal dialysis,while the remaining 19 patients received immunosuppressant (or with combination of glucocorticoid,angiotensin converting enzyme inhibitors and angiotensin Ⅱ receptor blockers.etc.) therapy.Among the 8 patients with renal vascular involvement,2 underwent surgery,and several received anticoagulant therapy.During the follow-up of 13 patients,the urine protein quantifications were reduced,and renal functions remained relatively stable.Conclusion Renal damage is relatively uncommon in BD patients.There are various clinical spectrums for renal BD.Routine screening with urinalysis,serum creatinine and imaging studies should be carried out for the early diagnosis of renal BD.

Radiation?induced brain injury is a common adverse reaction to radiotherapy for head and neck carcinoma, and may develop into radiation?induced brain necrosis in some patients. The disease has a substantial impact on the quality of life and 5?year survival in patients. Early diagnosis and prevention are important for the clinical treatment of radiation?induced brain injury. On the other hand, recurrence and pseudoprogression as complications of malignant tumor radiotherapy are also key problems for clinical diagnosis and identification of radiation?induced brain injury. Magnetic resonance imaging ( MRI) , especially functional MRI, provides an important approach for basic and clinical studies of radiation?induced brain injury.

BACKGROUND:Clinical application of neural stem cells is under exploration.Currently,the indicative differentiation of neural stem cells into specific neurons to replace lost and degenerative neurons needs to solve.OBJECTIVE:To explore the effect of 83 ku protein in rat hippocempi on inducing neural stem cell differentiation into acetylcholine esterase (ACHE) positive neurons.DESIGN,TIME AND SETTING:In vitro controlled observation of cytology was performed at the Medical College of Nantong University between October 2003 and April 2008.MATERIALS:A total of 12 SD rats,of clean grade,and SD fetal rats,aged 17 days,were provided by the Experimental Animal Center of Nantong University.METHODS:The normal hippocampi and hippocampi on the 14th day after the hippocampal fimbria transection were prepared into homogenate used for 10% native-polyacrylamide gel electrophoresis,and the differential proteins of 83 ku were electroeluted.The protein concentration was adjusted to 300 mg/L.The forebrain tissues of fetal rats were harvested and neural stem cells were isolated and in vitro cultured:blank control cells were cultured in serum-free DMEM/F12 medium;83 ku normal and 83 ku transection groups were separately cultured in serum-free DMEM/F12 medium containing 10 mg/L 83 ku protein from normal and hippocampal fimbria transection rats for 12 days.MAIN OUTCOME MEASURES:AChE histochemical staining was used to detect the differentiation of neural stem cells into AChE positive neurons.RESULTS:After 12 days of culture,there was a large amount of AChE positive neurons in 83ku transection group and their bodies were very big and the processes were abundant;The AChE positive neurons in 83ku normal group were less than 83 transection group,and their bodies were small with short processes.A few of AChE positive neurons were seen in control group.There were significant differences in number of AChE positive neurons among three groups (P＜0.05).CONCLUSIONHippocampal 83 ku protein can induce neural stem cells to differentiate into AChE positive neurons.
