Objective To analyze clinical materials and follow-up results of acute ECHO viral encephalitis in 35 children for improving recognition of this disease.Methods A total of 35 cases of acute ECHO viral encephalitis were retrospectively analyzed and followed-up,which were diagnosed.Results The clinical manifestations were as follows:headache(35 cases,100%),fever(35 cases,100%),vomiting(27 cases,77%),convulsion(8 cases,23%), positive meningeal irritation syndrome(30 cases,85%);the number of cells was(0～0.136)?10~9/L and the peak of protein was 0.8g/L in spinal fluid.30 cases(86%)had abnormal electroencephalogram,10 of which had abnormal CT scanning.18 patients were followed up,and 3(11%)of them had epilepsy seizure.The time of recovery of elec- troencephalogram was different and the longest time was 8 months.Conclusion The clinical features of ECHO viral encephalitis are non-specific of which mainly is meningoencephalitis with slighter state and better comprehensive treatment.The time for recovery of electroencephalogram is longer.Only few patients have epilepsy sequelae.

Objective To study the application and management of direct DR system and evaluate the imaging quality and reliability of DR system in Drum Tower Hospital since 2007.Methods General X-ray machines were reassembled into DR system,and new DR systems were purchased,in order to digitalize the radiological examination.Results 32,000 films were obtained by DR system.Conclusion DR system,with high-quality imaging,low radiation dose and high efficiency,can enhance the quality of clinical diagnosis.

Objective:To compare the positive rate and its coincidence with biopsy of HE staining-Pap's classification and Pap's staining-The Bethesda System(TBS).Methods:HE staining-Pap's classification were used to examine 4005 smears from January to June in 2001, while 2947 smears from April to August in 2002 were screened by Pap's staining-TBS. Meanwhile the abnormal cases were finally diagnosed by histopathology.Results:The positive rate of Pap's staining-TBS (5.29%) were significantly higher than that of traditional Pap's classification(0.32%)( P

Objective To investigate the efficacy and effects on cognitive functioning of antipsychotic addition to serotonin reuptake inhibitors in patients with treatment-refractory obsessive-compulsive disorder. Methods 58 therapy-resistant OCD patients were randomly grouped and receipt 8-week quetiapine-augmentation treatment or placebo respectively. At baseline and post-treatment, in order to evaluate symptom, executive functions, attention and memory, all patients were measured with Yale-Brown Obsessive-Compulsive Scale and cognitive functioning test, which included Wisconsin Card Sorting Test, Stroop Color Word Test,Continuous Performance Test and Memory Scale. Results Comparing quetiapine-augmentation group and placebo, there was significant difference of Y-BOCS total score between baseline and post-treatment (baseline:28.5±4.4,26.3±6.5,post-treatment:18.5±6.4,25.7±5.4, respectively,P=0.01). There was no major effects on cognitive functioning, apart from a failure to maintain set on the WCST (baseline:1.2±1.1,1.3±1.4,post-treatment:1.6±1.0,1.5±1.2,respectively,P=0.03).Conclusion It was effective of quetiapine-augmentation treatment on refractory OCD. There was no major effects on cognitive functioning of quetiapine-augmentation treatment.

Objective To study the effect of Fructus Aurantii Immaturus Decoction on defecating function of constipated mice.Methods Constipation mice models were induced by Compound Diphenoxylate.Defecating effects of Fructus Aurantii Immaturus on normal and constipation mice were observed.Results Middle and high dose of Fructus Aurantii Immaturus decoction could increase impelling rate of small intestine,shorten the time for the first dark stools(P<0.05 or P<0.01).and add the amount of dark stools within 6 hours(P<0.01).Conclusion Fructus Aurantii Immaturus has the functions of loosening bowel to relieve constipation.

Objective To explore the relationship between seizures and lacunar infarction in the elderly patients.Methods Totally 32 patients with seizures defined by International League Against Seizures (ILAE) and history of lacunar infarction as seizures group and 40 cases with lacunar infarction without seizures as control group were enrolled in our hospital Department of Neurology from Jan.2008 to May 2011.All patients were screened for risk factors of cerebrovascular disease and received magnetic resonance imaging (MRI) of the brain,electroencephalogram (EEG) and minimental state examination (MMSE). Results No significant differences between two groups were observed in vascular risk factors,distribution of the lacunar infarction focus (P＞0.05).The average score of MMSE were (22.31 ± 5.90) in seizures group and (21.85 ± 5.72) in control group with no difference (t=1.99,P=0.42).The focal or diffuse slow wave and epileptiform discharge on EEG appeared in 5 cases,7 cases and 3 cases in seizures group and in 4 cases,5 cases and zero case in control group,respectively,with remarkable difference in epileptiform discharge between two groups (x2 =3.91,P=0.04). Conclusions Seizures induced by lacunar infarction in elderly patients may be related to wide range of cerebral ischemia and hypoxia.

SUMMARY Rett syndrome (RTT) , an X-linked dominant neurodevelopmental disorder characterized by regression of language, stereotype hand movement and loss of purposeful hand use, is primarily caused by mutation of menthyl-CpG-binding protein 2 ( MECP2 ). The 76 kb human MECP2 is characterized by three sab'ent features; a very large intron 2 (60 kb) , an 8. 5 kb 3'-UTR with highly conserved regions and different polyadenylation sites, and a 40 kb intergenic region separating MECP2 from the nearest upstream gene. There are two isoforms of MeCP2, MeCP2el and MeCP2e2. The differences between the two isoforms, the function of the 3'-UTR and the long-range cis-regulatory sequences in the intergenic region were extensively studied. In contrast to initial report, recent studies show that MeCP2 binds not only to methylated promoters and silence transcription, but also to the sites outside of genes containing only a few of CpG islands. Furthermore, MeCP2 can function as both an activator and a repressor of transcription.

The effects of cytochalasin D (CD), isolated from Engleromyces goetzii found in our country, on cells of established human esophageal cancer line (ECa-109 cell line) were investigated. It was demonstrated that CD was capable of inhibiting the growth of the cells at the concentration of 0.2?g/ml as indicted by growth curve. The action of CD, however, is reversible, and the cells will gradually grow again normally following the withdrawal of CD. The result also indicated that some proportion of the cells became binucleated or multinucleated after CD treatment. And as the duration of exposure time to CD increased. the multinucleated cells increased in number also. At the concentration of 0.5?g/ml of CD, a phenomenon of extrution of nucleus can be seen among the cells. The nucleus is departed from the cell body but still linked by a fine cytoplasm bridge (Fig. 2). The CD-treated cells bacame enucleated when they subjected to centrifugation following CD treatment. The minicells obtained from enucleation appeared to be normal morphologically with nucleoli but retained only a little cytoplasm around the nucleus. Electromicroscopic observation showed that mitochondria and tonofibrils increased after CD treatment, but we failed to find any changes of microfilaments within the cells.
