The occurrence of epilepstic seizures in patients with cerebral palsy (CP) remains a serious event and is very disruptive for children who already suffered from orther disabilties. Data from population-based studies or neurodevelopmental clinic studies showed that 8%~62% of patients with CP suffer from epilepsy. The incidence is highest in spastic tetraplegia and hemiplegia. Half of the patients were onset within the first year of age. Children with tetraplegia CP tended to have an earlier onset of epilepsy than chlidren with other CP types. Partial seizures were the most common seizure types, followed by infantile spasms and Lennox-Gastaut syndrome. Low birth weight, neonatal seizures, family history of epilepsy, lower intelligence and grey matter damage were found to be related to significantly increased risk of epilepsy. Epilepsy in children wih CP usually had poor outcome, half of them were intractable and needed polytherapy. Only 37%~65.2% of patients became seizure-free.

The antagonism of two strains B1 and B2 of Bacillus spp. against pea root rot pathogen Fusarium oxysporum f. sp. pisi was studied. The result of pairing culture showed that B1 and B2 strains of Bacillus spp. had strong antifungal activity to the pathogen. The colonial color of the pathogen changed from gray to white, aerial hyphas increased and entangled into group after treatment with the cell-free fermentational filtrate of B1 or B2. Observation under optical microscope showed that hyphas and spores of the pathogen swelled and distorted with concentrated cytoplasm after treatment, the spores could not germinate or germinated abnormally . A lot of vesicles appeared at the top of the hyphas, and the hyphas stopped growing and broke finally, their cytoplasm spilled from the cell. The cell-free fermentational filtrate of B1 or B2 strains contained 1795.53?g/mL and 1345.93?g/mL protein respectively, from which two antifungal proteins of 103.5 kD (B1 ) and 127.6 kD (B2) were purified.

Objective To investigate the relationship between polycystic ovary syndrome (PCOS) susceptibility single nucleotide polymorphisms (SNP) and metabolic phenotypes in glucose and lipid metabolism and explore the pathophysiological mechanism of the susceptibility genes.Methods Three of PCOS susceptibility locus 2p16.3 (rs13405728 of LHCGR gene),2p21 (rs13429458,rs12478601 of THADA gene) and 9q33.3 (rs2479106,rs10818854 of DENNDIA gene) were selected and the metabolic phenotypes were compared between different genotypes of SNP in PCOS patients (using dominant model).Results Low-density lipoprotein cholesterol was significantly increased in CC genotype group than in TC + TT groups at rs12478601 of THADA gene [(2.5 ± 0.8),(2.4 ± 0.8) mmol/L; P =0.01].Serum insulin level of 2 hours after 75 g glucose intake was significantly higher in GG + AG groups than that of AA group at rs2479106 of DENND1A gene[(71 ±65),(64 ±50) mU/L;P =0.05],and the prevalence of type Ⅱ diabetes in first-degree relatives of patients were also increased [9.9% (66/666),6.9% (52/751) ; P < 0.05].No association was found between metabolic phenotypes and genotypes of rs13429458,rs10818854,and rs13405728.Conclusions Genetic factors probably have effect on the metabolic characteristics of PCOS.THADA gene is related to lipid metabolism,while DENND1A gene may be involved in insulin metabolism in patients with PCOS.

Objective To study the protective effect of total flavones of hawthorn leaf (TFHL) on renal ischemia/reperfusion (I/R) in rats.Methods A model of renal I/R was made by clamping double renal pedical for 60 min and reperfusion for 24 h.TFHL (30 or 60 mg/kg) was injected before clamping renal ischemia. The level of serum urea nitrogen(BUN), serum creatinine(Scr), tumor necrosis factor-?(TNF-?),interleukin-1(IL-1) in serum were detected after reperfusion for 1 and 24 h,respectively,and the level of malonaldehyde (MDA) and erythrocuprein (SOD) in renal tissues were measured after reperfusion for 24 h.Results TFHL significantly decreased the level of BUN and Scr, decreased the concentration of TNF-? and IL-1 in serum. Pretreatment with TFHL also enhanced the activity of SOD reduced the concentration of MDA in renal after I/R.Conclusions TFHL has significantly protective effect on renal I/R and markedly improve the renal function. The mec-hanisms are associated with decreasing the lipid peroxidation reaction and reducing the level of TNF-? and IL-1.

Objective To investigate the effects of adiponectin on the development of atherosclerosis.Methods The in vivo role of adiponectin on the development of atherosclerosis in rabbits was investigated mainly using adiponectin-producing adenovirus(Ad-APN)and intravascular ultrasound(IVUS).On day 14 after Ad-APN local transfer to the intima of abdominal aortas,abdominal IVUS images were recorded and then rabbits were sacrificed.Abdominal aortas were collected and performed histochemical analysis.Results Ultrasonography revealed a significantly reduced atherosclerotic area,in abdominal aortas of rabbits infected through intima with Ad-APN,by 36.39% compared with the area in adenovirus expressing β galactosidase gene(Ad-βgal)treated rabbits(P<0.01),and by 37.50% compared with that before treatment(P<0.01).The lumen area stenosis was also reduced by 23.37%(P<0.05)and 33.15%(P<0.01),respectively.In rabbits with Ad-APN infection,the atherosclerotic plaque area as seen on Oil Red O staining was reduced significantly,by 30.70%(P<0.05)and the greatest thickness of plaque was reduced,by 20.83%(P<0.05)as compared with those in Ad-βgal-treated rabbits,respectively.Conclusions Intravascular ultrasound analysis is a valuable method in the in vivo study about the effects of adiponectin on the development of atherosclerosis.

Background Central corneal thickness (CCT)is an important parameter to evaluate corneal healthy status and is crucial for surgical planning.However,clinical study found that the center of cornea does not correspond to the thinnest point of cornea.Thus,it is essential to characterize the minimum corneal thickness(MCT) and its location.Objective Present study was to determine the thickness and location of MCT and its relationship to the fellow eye using Pentacam High Resolution technique.Methods The 564 eyes from 282 Chinese myopic patients were reviewed in this study.The CCT,MCT,pupillary central corneal thickness(PCT) and x-y coordinate of thinnest point were bilaterally measured.Written informed consent was obtained prior to the ocular biomedical measurement.Results CCT was (540.07±31.78) μm in the right eyes and (539.24±31.06) μm in the lefi eyes; PCT was (540.25±30.75)μm in the right eyes and (539.48±31.00)μm in the left eyes.MCT was (537.87± 31.91)μm in the right eyes and (536.35±31.24)μm in the left eyes,showing significant differences in all the parameters between the right eyes and left eyes expect for PCT(CCT:P=0.046;PCT:P=0.065 ;MCT:P=0.000).The C CT,PCT and M CT were significantly correlated between the right eyes and left eyes (r =0.97,0.97,0.98,P< 0.01).Bland-Altman plot showed a good consistence between the both eyes.The mean distance from the center was (0.50±0.21) mm in the right eyes and (0.56±0.22)mm in the left eyes,showing a significant difference (P =0.000).The difference between CCT and MCT was approximately (2.20±1.74)μm in the right eyes and (2.88±1.75) μm in the left eyes.The location of MCT in both the right eyes and left eyes tended to symmetry along the vertical midline.The distance between the R (x,y) to transformed L (x,y) was (0.29 ± 0.17)mm and the angular distance was (28.28±28.21)degree.Conclusions This study offers a range of MCT and its location in Chinese myopic patients.The difference exists between the CCT and MCT in bilateral eyes.The location of the thinnest point tends to be symmetrical along the vertical midline between the both eyes.The changes of these parameters may be helpful for the diagnosis of some corneal diseases.
