Objective To study the etiology,clinical characteristics,electroencenphalography(EEG),mental degree of Lennox-Gastaut syndrome(LGS). Method Retrospectively analyzed etiology,sex,age,seizure types,EEG,mental degree of 54 children diagnosed as LGS. Results The number of male was 36,female was 18,seizure onset from 1 month to 8 years,diagnosing age from 3 months to 11years. The EEG reveals 1.5-2.5 Hz spike-wave discharges and a slow baseline activity. Conclusions LGS is one of the most difficult epilepsys to treat and need frequently more than 2 antiepilepsy drugs. It is characterized by variable etiology,multiple types of intractable seizures, and has enormous detrimental effects on patient′s developmental health.

We have found the parallel relationship between the live cell number of several tumor cell lines and the formation of MTT formazan with MTT colorimetric assay. The MTT colorimetric assay was compared with ~3H-Tdr incorporation assay for the proliferation of mouse spleen cells induced by mitogens or the activity of rat/mouse IL2,the results suggested that the ~3H-Tdr incorporation assay can be replaced by MTT colorimetric assay. MTT colorimetric assay have the advantages of simplicity, rapidity,save any radioisotope and no specific equivepment, etc, so under some conditions it would be a useful method for measuring cell proliferation or cytotoxicity in a laboratory.

Objectives To investigate and evaluate the preventive and therapeutic effects of celecox ib,a selective cyclooxygenase-2(COX-2)inhibitor,on multiple colorectal adenorna and compare it with aspirin.Methods Ninty-six patients with colorectal multiple adenoma were randomly divided into A,B and C groups.Adenomas in all patients were removed with high-frequency eleetrocoagulation,electroexci- sion or argon plasma coagulation(APC)under colonoscopy.Then,group A were administered celecoxib 200 mg twice daily,group B aspirin 50 mg twice daily,group C served as control.Colonoscopy was per formed every 6 months in the first year,and every year in order to observe and evaluate the recurrence rate of adenoma and the side effects after the treatment.Results Twenty-seven patients in group A,26 pa- tients in group B and 27 patients in group C had completed the treatment.At the end of the treatment, on PP/ITT analysis,the cure rate of the eolorectal adenoma were 84.4%/100% ,78.1%/96.2% and 75.0%/88.9% in group A,B and C,respectively.During the first year of follow-up,there were 1 ,1 and 6 cases which were found recurrences of the adenomas in group A,B and C,respectively.The recurrence rates of coloreetal adenomas in group A(3.7%)and group B(4.0%)were significantly low er than that in group C(24.0%) (P＜0.05 and＜0.05,respectively).At the end of follow-up,the total recurrence rate of colorectal adenomas in group A(14.80%)and group B(19.2%)were significant- ly lower than that in group C(46.2%)(P＜0.05 and＜0.05).While the side-effective rate regroup A (3.3%)was significantly lower than that in group B(22.5%)(P＜0.05).Conclusions After re- section of the multiple colorectal adenomas,both the selective inhibitor of COX-2,celeeoxib and the non- selective inhibitor of COX-2,aspirin,may reduce its recurrence rate,but the former has a good tolerance and lower side-effects.

Objective To investigate the changes of serum cardiac troponin I(cTnI)and brain natriuretic peptide(BNP)in heart failure of children with pneumonia and their relationship with heart function.Methods Thirty healthy children aged from 5 months to 3 years old were randomly selected with 17 male and 13 female(healthy group).Thirty children with severe heart failure aged from 3 months to 2 years old were selected at the same time with 21 male and 9 female(heart failure group).Thirty children with ordinary pneumonia aged from 3 months to 3 years old were also sampled with 16 male and 14 female(ordinary pneumonia group).The peripheral bloods of 2-3 mL of all children were taken.The BNP level were measured by enzyme-linked immunosorbent assay and the cTnI level was determined by micro-particle enzyme immunoluminescent.Left ventricular ejection fraction(LVEF) and left ventricular fractional shor-tening(LVFS)were detected by echocardiography.SPSS 11.0 software was used to analyze the data.Results The levels of cTnI [(0.389?0.030) ?g/L] and BNP [(0.572?0.090) ?g/L] of heart failure group increased significantly compared with healthy and ordinary pneumonia group,while their LVEF and LVFS decreased significantly(Pa

Objective To explore the related diseases,main causes and clinical features of children with basal ganglia calcification(BGC).Methods Thirty cases with BGC detected by CT were studied retorspectively,and its clinical symptoms and image were summarized.Results Many factors and diseases were related to BGC,such as hypothyroidism,intrauterine infection,intrauterine hypoxia,epilepsy,posttraumatic cerebral lacunar infarction.Main clinical manifestations of BGC in children were twich,mental retardation,disorders of limb movements etc.The CT scan showed localized punctuate calcification in basal ganglia.Conclusions The main causes of BGC in children are hypothyroidism,intrauterine infection and intrauterine hypoxia,and the clinical manifestations are diverse.For children with CT-detected BGC should diagnose its causes;and for unknown causes cases should strengthen follow-up.
