Objective To explore sub-clinical items in evaluating the prognosis of epileptic patients,the study on differences of regional cerebral blood flow (rCBF) in both effective treated and incomplete-controlled patients with idiopathic generalized tonic clonic seizure (GTCS) was carried out.Methods Interictal rCBF measurements using 99m Tc-ethyl cysteinates dimmer (ECD) SPECT was performed on 29 effective treated idiopathic GTCS patients and 12 incomplete controlled idiopathic GTCS patients. The rCBF distribution was semi-quantitatively analyzed by regions of interest (ROIs) comparing with abnormal rate of interictal hypoperfusion rCBF,clinical seizure time and EEG.Results ROI analysis showed that rCBF decreased in basal ganglia and thalamus of incomplete controlled patients with idiopathic GTCS compared to that of effective treated ones′ significantly ( P

Ion trap performances are investigated based on digital ion trap technique with different collision gases at different pressures. Collision gases of helium (4 amu), nitrogen (28 amu) and argon (40 amu) with various pressures are adopted in ion excitation and dissociation stages to investigate the ion trap performances, including mass resolution, signal intensity, tandem mass spectrometric analysis ability and low-mass cut off (LMCO) effect. It is found that when heavy gas of argon is used, energy can be efficiently transferred and LMCO effect is decreased with higher ion capture and dissociation efficiencies but with low mass resolution. Higher mass resolution is realized with helium as collision gas. Furthermore, at the same gas pressure, heavy gas is beneficial to abundant fragment ions and structural information of precursor ion.

Objective To compare the scores of amplitude-integrated electroencephalogram (aEEG) tracings between preterm infants who were smaller for gestational age (SGA) and those who were appropriate for gestation (AGA).Methods A total of 139 preterm infants were collected in the Neonatal Intensive Care Unit of the Affiliated Hospital of Guangdong Medical College during the period of Mar.2013 to Feb.2014.One hundred and fourteen patients met the inclusion criteria with gestational ages from 32 to 36 weeks at birth,including 54 SGA infants and 60 AGA infants.The aEEG recordings were obtained within 72 h after birth by using the NicoletOne monitor.Duration of each recording was at least 3 h.Five aspects of each tracing,such as continuity (Co),sleep-wake cycling (Cy),amplitude of the lower border (LB),bandwidth (B) and total maturation scores,were evaluated and compared between 2 groups by applying a aEEG scoring system.Results 1.As SGA infants,scores for Co,Cy,LB,B as well as total maturation scores were progressively increased with gestational age advancing(all P ＜ 0.05).As AGA infants,scores for Cy,B and total maturation scores progressively increased with advancing gestational age (all P ＜ 0.05),but there were no statistical differences between each gestational ages in Co,LB scores (all P ＞ 0.05).2.Linear regression analysis of SGA infants' gestational age to Co,Cy,LB,B and total maturation scores showed positively correlation,and the correlation coefficients were 0.438,0.597,0.385,0.606 and 0.608,respectively (all P ＜ 0.05).As AGA infants,a positive correlation between gestational age and Cy,B as well as total maturation scores were observed,and the correlation coefficients were 0.528,0.615 and 0.635,respectively (all P ＜ 0.05).3.At the same gestational age,both the B scores and total maturation scores in SGA group were lower than those in AGA group.Conclusions SGA and AGA,Co,Cy and total maturation scores can be used to evaluate the maturation of cerebral function.At the same gestational age,the scores of B and total maturation scores are lower in the SGA,and this might be associated with their delayed neuromotor development.

Urinary 8-oxoGsn/Cre levels were positively correlated with age, time of 5-times sit to stand test, AGEs, fasting blood glucose, mercury and aluminum( rs=0.443, 0.292, 0.357, 0.205, 0.316 and 0.214, P<0.05), and negatively correlated with trunk muscle mass, appendicular skeletal muscle mass, fat-free mass, grip strength, silicon and manganese( rs=-0.334, -0.333, -0.332, -0.366, -0.246 and -0.234, P<0.05), with statistical significance. Conclusions:Increased urinary 8-oxoGsn/Cre levels are correlated with decreased muscle mass, poor physical function, accumulation of AGEs, decreased trace element levels and increased heavy metal levels.Therefore, 8-oxoGsn has the potential to be a broadly representative and sensitive indicator for health assessment.

AIMTo investigate the effects of RLI on plasma nitric oxide (NO) and NO synthase (NOS) isoforms of healthy humans.

METHODS30 healthy human subjects (aged from 40 - 70 years old) were recruited. RLI was induced by five 5 min cycles of ischemia of non dominant arm (200 mmHg, 5 min interval). Blood pressure, heart rate, and the feelings of ischemic arm were continuously monitored. Venous plasma was collected in contralateral arm at Pre, Post-0 h, Post-4 h, and Post-24 h. Plasma level of NO was measured by Griess reaction, and NOS was measured by chemical method.

RESULTSBlood pressure and heart rate varied in normal range. The uncomfortable feeling was decreased with the increasing numbers of ischemic cycles. Plasma level of NO, and iNOS in plasma were significantly increased at Post-0 h, Post-4 h, and Post-24 h compared to Pre (P < 0.05). tNOS was also significantly increased at Post-0 h and Post-4 h compared to Pre (P < 0.05). No significant change in plasma cNOS was shown at following three time points than Pre.

CONCLUSIONThese findings suggest that RLI can elevate plasma level of NO, tNOS, and iNOS in healthy humans. RLI might be a safe method as a rIPC, and it would have important possibility to be performed in clinic.

To generate transgenic mice in which both hygromycin (hyg) and neomycin (neo) resistance genes are expressed in murine fibroblast cells (MEFs), which are required for conditional gene knock-out and screening of drug resistant ES cell clones. To construct HygR-neoR expression vector, pTK-hygR-pA and PGK-neoR-pA were cloned into pBluescript vector. DNA fragments of tandem genes ( 4245bp ) were prepared by Kpn I and Xba I digestion and transgene was microinjected into pronucleus of zygotes to generate transgenic mice. Transgenic mice were identified by PCR and Southern blot; expression of hygR and neoR gene transcripts were detected by RT-PCR. 7 founder mice carrying hyg-neo resistant genes were obtained and 6 transgenic mouse lines were successfully established. The hygR and neoR gene transcripts were detected in the liver and/or ovary of transgenic mice from hn30, hn33, hn66 and hn67 mouse lines. In MEFs isolated from the mice of line hn66 and hn30, expression of hyg and neo resistant genes was also detectable. Transgenic mouse lines expressing two anti-drug genes have been established. The hyg and neo resistant gene transcripts were detected in the MEFs of two transgenic mouse lines.

OBJECTIVETo analyze the characteristic of bacterial infections, and the relationship between antibiotics treatment and bacterial infections after liver transplantation, and to prevent antibiotic-resistant bacterial infections.

METHODS86 liver transplant recipients were retrospected. Different indexes including limited daily dose, the frequency of medication, drug use index were used to evaluate the rationality of the use of antibiotics, three-dimensional test was used to explore extended-spectrum beta-lactamase and AmpC enzyme of Gram-negative bacteria.

RESULTSThe major pathogens of infection after liver transplantation were Enterococcus faecalis, Enterobacter cloacae, fungi and E. coli. Pre-operative antibiotic utilization rate was 83.7%, it was mainly a single use of antibiotics; After- operative antibiotic usage was 100.0%, it was mainly joint use of two or three antibiotics; The top 3 antibiotics used were cephalosporins, the combined enzyme inhibitors and penicillin. Antibiotics with drug utilization index (DUI) more than 1.1 included ampicillin and Lalin proxy. 43.3% and 31.8% of Gram -Negative bacteria produced ESBLs and AmpC, respectively, while 21.3% Gram -Negative bacteria produced two enzymes.

CONCLUSIONThere is high incidence of bacterial infections after liver transplantation. The use of antibiotics is high dose, high-frequency and reasonable; High resistance of bacterial infections was prone to develop and the prevention of the high resistance of bacterial infections is very important.
