Objective A retrospective study was conducted to evaluate the clinical significance of Video EEG monitoring in the diagnosis of epilepsy and other paroxysmal events Methods Video EEG monitoring under the state of awaking and sleeping and evoked tests were performed continuously in 216 patients with epilepsy and other paroxysmal events Results The characteristic events were captured in 130(60%) of the 216 patients And out of the 130 patients, 53 had clinical events accompanying epileptiform discharge 73 patients had no epileptiform discharge in both ictal and interictal period Seizure types were defined in 80%of 80 patients with epileptiform discharge, and classification was different from the original 42% of the 64 patients Conclusions Video EEG can record much more epileptiform discharge than routine EEG It should be an effective method in both diagnosis and classification of epilepsy

Messenger RNA was isolated directly from lung cancer cell line A549 using magnetic particles. First strand synthesis from mRNA was driven by M-MLV(Moloney Murine Leukemia Virus) reverse transcriptase and random hexam-eric primer, followed by second strand synthesis using RNase H and DNA polymerase I After treatment with T4 DNA polymerase to flush the ends, the double-stranded cDNA was cloned into the plasmid expression vector digested with EcoRI and followed by removing cohesive end. The number of independent clones of the resulting cDNA library was about 9.0 x 105. The estimated percentage of colonies with inserts was about 85 % . The insert size ranges from 0.5 kb ~ 4 kb. The CPP32 gene coding for death protease was obtained by PCR with the cDNA library from lung cancer cells as a template for the first time. Construction of the cDNA library laid a foundation for screening other genes regulating death of lung cancer cells.

The quality and function of the donor liver is one of the main factors which influence the success and prognosis of liver transplantation.At present,the major source of donor liver for transplantation is Donor of Brain Death (DBD) all over the world,which has unstable circulation.When the brain death occurs,a series of serious physiological function changes will be induced within a few minutes and affect the hemodynamics and homeostasis of the body,which will greatly influence the liver quality and function,and consequently the success and prognosis of liver transplantation,finally leading to the loss of potential donor organs.Therefore,it is necessary to identify the physiological function changes induced by the process of brain death and its injury to liver and take immediate proper protective measures,which can effectively reduce the organ injury,improve liver function and enhance the organ utilization and liver transplantation success.In this paper,the changes and maintenance measures of liver physiological function in DBD will be reviewed.

Objective To investigate the effect of tourniquet compression on axonal transport in sciatic nerve of rats.Methods Twenty-four 12-week old male SD rats weighing 250-300 g were randomly divided into 4groups according to the duration of tourniquet compression(n=6 each):1,2,4 and 12 h.The tourniquet was applied to the middle 1/3 of thigh.In each animal whether the left or right thigh was compressed was determined by a flip of coin.The tourniquet was released for 10 min after every hour of compression.A 3-cm segment of sciatic nerve was removed at the end of tourniquet compression(1.5 cm proximal and 1.5 cm distal to the site of compression).Immuno-histochemistry was used to measure the expression of insulin-like growth factor-1(IGF-1)in the sciatic nerve.The ratio of average optic density of the compressed sciatic nerve to that of control was used to estimate the degree of IGF-1 accumulation.The regression equation of the interaction between the duration of compression and accumulation of IGF-1 was analyzed.Results There was significant accumulation of IGF-1 in the sciatic nerve proximal to the compressed site.The accumulation increased with the duration of compression.There was no significant accumulation of IGF-1 in the sciatic nerve distal to the compressed site.The regression equation of the interaction between the duration of compression(X)and accumulation of IGF-1(Y)was Y=0.422X+0.887.Conclusion Tourniquet compression of sciatic nerve can inhibit axonal transport.The accumulation increases with the duration of compression.

Objective To quantify the white matter hyperintensity (WMH) with serial MRI in elderly people with cerebrovascular disease, and to evaluate the risk factors that may have impact on their progression.Methods One hundred and thirty-eight patients with cerebrovascular disease underwent twice MRI scans with a 1.5T MR scanner at least one year apart (mean = 13.8 months). The clinical data of all patients, including age, gender, systolic blood pressure, blood glucose level, serum lipid level, alcohol consumption and smoking were recorded at baseline, as well as the historical informations concerning hypertension, diabetes mellitus and hypercholesterolemia. Besides, the overall severity of cognitive impairment and neural deficit of patients were rated by Mini-Mental State Examination (MMSE) and the National Institute of Health Stroke Scale (NIH). MRI measures included volume of gray matter infarction, volume of white matter infarction, and baseline volume of WMH. The volumetric changes of WMH between the twice scans were assessed using a semi-automated software. The influence of risk factors on changes of WMH volume was analyzed. Correlation coefficients were calculated between clinical scales and the change of WMH volume. Results The Baseline WMH volume was(13155?18782) mm3, and the volumetric change of WMH was(7687?9079) mm3. Multiple regression analyses revealed that the occurrence of infarction in cortex and in white matter was significantly associated with the volumetric change of WMH, as well as the baseline WMH volume. The volumetric changes of WMH were related to MMSE and NIH score (r=-0.266,P=0.002; r=0.257,P=0.002). The total infarcted volumes were associated with the volumetric change of WMH (r=0.416,P

Objective To investigate the correlation between microalbuminuria (MAU) and obesity and its indexes, including BMI, waist circumference(WC), and waist-to-hip ratio(WHR) , among partial community population in Beijing. Methods A total of 2080 subjects who took physical examination in Beijing, including 810 men and 1270 women with a mean age of(50. 9 ± 13. 1 )years, were enrolled. The informed consent has been achieved from each patients. BMI and WHR were calculated based on collected data of height, weight, WC, and hipline. Urine albumin-creatinine ratio(ACR) within the range of 30-300mg/g was classified as MAU. The subjects were divided into normal albuminuria ( NAU ) group and MAU group. The correlations between MAU and different obesity indexes including BMI, WC and WHR, were analyzed. Results Among the 2080 subjects, there was a positive correlation between BMI (r = 0. 1276,P＜0.01) and ACR, and WC (r = 0.0840, P ＜0.01) and ACR. WHR and ACR was irrelevant ( P ＞ 0. 05 ). In univariate analysis, there was significant difference in BMI ≥ 28 kg/m2 ( OR = 2. 02 ) and WC ≥85 cm (male) or≥80 cm (female) (OR = 1.69 ) between NAU group and MAU group (P ＜ 0. 05 ).There was no significant difference in BMI 24-＜ 28 kg/m2, and WHR ≥0. 90 (male) or ≥0. 85 (female)between NAU group and MAU group( P≥0. 05 ). Multivariate logistic regression analysis revealed that BMI ( OR = 1.06) was an isolated independent risk factor of MAU from age ( OR = 1.01 ), female ( OR = 1.42),systolic blood pressure (OR=1.01), TC (OR=1.93) and HDL-C (OR=0.54). Conclusions Obesity is an independent risk factor of MAU among partial community population in Beijing. The correlation between different obesity indexes and MAU also differs.
