Objective To explore the effect of valproate(VPA) on body mass index(BMI),leptin and serum lipids in children with epilepsy.Methods (Twenty-)four cases with epilepsy were selected.BMI and serum levels of leptin,total cholesterol(TC),(triacylgly)-cerol(TG),high density lipoprotein-cholesterin(HDL-C),low density hipoprotein-cholesterin(LDL-C) after treated with VPA for 3 months and 6 months were determined.Results The levels of BMI,leptin,TC,TG,LDL-C after treated 3 months were all significantly higher than those of initial(all P0.05).Those in treated 6 months were same as levels of treated 3 months.Only LDL-C level was lower than that of 3 months and same as level of before treatment.Conclusion VPA do have efficacy to cause obesity in children with epilepsy,and most of the cases occur in the first 3 months after VPA treatment.

Objective To discuss the CT characteristics of AIDS's brain common disease,so that to improve the diagnostic level.Methods CT features of brain lesions in 25 patients with AIDS were retrospectively analyzed.Results Acute HIV encephalitis(n=6),CT features included low density at the basis festival area and the ventriculi laterals,no enhancement on contrast-enhanced scan in 1 case.Subacute HIV brain illness(n=5),CT images showed different degree of atrophy.Toxoplasmosis(n=4),CT images showed iso-dense tubercles with edema in the deep part of brain white matter or iso-dense circle at the edema area.Cytomegalovirus encephalitis(n=3),CT images showed symmetrical low density at bilateral cerebral occipital lobe,internal capsule and thalamus.Progressive multifocal leukoencepathy(n=3),CT showed multiple low density at the inferior surface of brain cortex,the gyri close of focus was clearer,and far of tapetum room system.Mixed infectious(n=4),mixed CT characteristics.Conclusion CT is beneficial in the differential diagnosis of brain disease in AIDS.

ObjectiveTo investigate the effect of β-adrenergic receptor(β2AR) stimulation on vascular smooth muscle cell apoptosis in physiological state and receptor overexpression model.Methodsβ2AR overexpression model was established by transgenic techniques. Hoechst 33342 staining as well as flow cytometer(FCM) detected were chosen to measure the incidence of vascular smooth muscle cell apoptosis.ResultsVascular smooth muscle cell exhibited significantly fewer viable cell rate when stimulated with β2AR agonist isoproteronol for 48 hours compared with control (P<0.01),while no difference at the time point of 24 hours. Much fewer viable rate detected by FCM and high apoptotic rate by Hoechst staining were observed when VSMCs overexpressing β2AR were stimulated with isoproteronol for 24 hours (P<0.01).ConclusionStimulation of physiological and overexpressing β2AR could induce apoptosis of vascular smooth muscle cell.

Among them, compounds 1-3, 6-9, 11, and 14 were isolated from E. dracunculoides for the first time, and compounds 10, 12, 13, 15, and 16 were firstly obtained from the genus Euphorbia. Their structures were elucidated by spectroscopic analysis, including 1H-NMR, 13C-NMR, and ESI-MS.

Objective To investigate the prevalence of integrons in A.baumannii isolates,analyze the correlation between inte- grons and resistance of A.baumannii,and study the resistance genes in integrons.Methods A total of 106 strains of A.bau- mannii were collected to test the antibiotic susceptibility by disk diffusion method.The classification of integrons was per- formed by analyzing the positive PCR products using restriction fragment length polymorphism (RFLP).The variable region of integrons was amplified by integron PCR.RFLP and DNA sequencing were used to analyze the resistance genes in integrons. Results About 52.8% (56/106) of the isolates showed integron positive.PCR-RFLP analysis revealed that they were all class I integrons.About 94.6%(53/56) of the positive strains with integrons owned the variable region,which was confirmed by integron PCR.The sizes of the amplicons ranged from 0.15 kb to 2.8 kb.All together 7 different cassette arrays were detec- ted,including genes coding resistance to aminoglycosides (aadA1,aadA2,aadA5,aadB,aacA4),sulphonamides (dfrⅫ, dfr17),?-lactam compounds (bla_(ara-10)),chloramphenicol (catB-like,catB8),and two open reading frames (orfF,orfI) with unknown function.A novel cassette array orfI-aadA1 was reported,and its GenBank accession number was DQ092497.Conclu- sions Class I integrons are widespread in A.baumannii isolates in Nanjing.The integrons are closely associated with the resist- ance and multidrug resistance in A.baumannii isolates.

Objective To study the effects of pulsed electromagnetic fields(PEMFs)of 15Hz and lmT on osteoblast differentiation of bone marrow mesenchymal stem cells.Methods The bone marrow mesenchymal stem cells were isolated and cultured in vitro,the third passage cells were harvested and half of them was exposed to PEMFs,another half exposed to sham PEMFs served as the control.The activity of ALP was measured.And the ex- pression of osteoblast and adipogenesis was measured with the semi-quantitative RT-PCR,adipogenic differentiation was observed with the Oil Red O Staining.Results When compared with the control,PEMFs of 15 Hz and 1 mT significantly increased the activity of ALP(P

ObjectiveTo investigate the value of a digital three-dimensional reconstruction technique in the treatment of hepatic alveolar echinococcosis (HAE).MethodsThe computed tomography scan data for 13 patients with HAE who were admitted to the First Affiliated Hospital of Xinjiang Medical University from February 2011 to October 2011 were reconstructed and analyzed by a three-dimensional reconstruction system to assess resectability,and to facilitate surgical planning and individualized virtual surgery.The results of preoperative analysis were compared with the results of actual operations.ResultsThe three-dimensional models of the liver were reconstructed successfully,and intrahepatie lesions and vessels were clearly displayed.One patient received an autologous liver transplantation,10 underwent hepatectomy,and 2 received percutaneous transhepatic cholangial drainage.Virtual operation planning was carried out for 11 patients using the three-dimensional reconstruction system.The mean volume of the liver to be resected was predicted to be 920 ml (range,339-2678 ml),and the mean percentage of liver to be resected to the total liver volume was predicted to be 45％ ( range,23％ -68％ ).The mean volume o[ the actual liver resection was 834 ml (range,315-2250 m[),and the mean percentage of actual liver resected to the total liver volume was 42％ (range,22％ -70％ ),which was consistent with the results of preoperative three-dimensional reconstruction.All patients were followed up for 2-8 months,and no severe complications such as liver failure,hemorrhage and bile leakage were detected.ConclusionDigital three-dimen-sional reconstruction is helpful in the diagnosis and treatment of HAE and effectively reduces surgical risks.

OBJECTIVETo investigate whether intracytoplasmic sperm injection (ICSI) can improve the clinical outcomes of the male patients with 100% teratozoospermia.

METHODSWe retrospectively analyzed the clinical data of 152 couples undergoing in vitro fertilization-embryo transfer (IVF-ET), including 75 cycles of IVF and 77 cycles of ICSI. We compared the rates of normal fertilization, high-quality embryos, transferrable embryos, implantation, clinical pregnancy, and abortion between the two groups.

RESULTSIn the 100% teratozoospermia patients the number of transferrable embryos was significantly lower in the IVF than in the ICSI group (78.91% vs 84.92%, P < 0.05), while the rates of normal fertilization and implantation were higher in the former than in the latter (60.26% vs 57.87% and 48.00% vs 39.55%, both P > 0.05). There were no statistically significant differences between the two groups in the female age, Gn days, Gn dose, BMI, infertility duration, endometrial thickness, and basal serum FSH and E2.

CONCLUSIONICSI cannot improve the clinical outcomes of the male patients with 100% teratozoospermia.
