ObjectiveTo explore the relative factors of the compliance in schizophrenic out-patients.Methods118 schizophrenic out-patients chosen randomly were investigate with the compliance and assessed with Clinical Global Impression-Severity of Illness (CGI-SI), Social Disability Screening Schedule (SDSS), Brief Psychiatric Rating Scale (BPRS) and Treatment Emergent Symptom Scale (TESS) by telephone. Logistic regression analysis was used to confirm the relative factors of the compliance.Results56.8% of all patients were of full compliance. The risk factors of compliance in schizophrenic out-patients were the frequency of medicine taken, the scores of CGI-SI and the insight of the illness. ConclusionIt is important to choose effective and convenient antipsychotic drugs and improve the insight of the illness to enhance the compliance of the schizophrenic out-patients.

Changes in behaviour relevant to the vestibular system were studied in Long-Evans rats which were fertilized, born and housed in 2 acceleration of gravity for 4 months and thereafter exposed to 1 acceleration of gravity, and expression of Fos protein in the brain stem was examined. Data from the hypergravity rats were compared respectively with those from the rotation group and the labyrinthectomized group. Static and locomotion modes of the hypergravity rats were changed, tension of extensor was enhanced and the abilities in locomotion equalization and orientation in swimming and air-righting response were reduced. The adaptation process varied with different behaviours. The time for recovery of the ability of orientating in swimming was the longest, taking more than 1 month. The Fos protein expression provides a useful tool for mapping brain functional activities after sensory stimulation, showing a low basal level in normal and labyrinthectomized groups. The hypergravity rats, on the other hand, exhibited more Fos-positive cells in the superior colliculus, inferior colliculus, periaqueductal gray, raphe dorsal nucleus and solitary nucleus. In contrast, the inferior olivary nuclei, locus coeruleus and vestibular nuclei were not strongly labeled. These spatial patterns of Fos expression suggest that a decrease in gravity-inertial force may activate a neural pathway different from the vestibulo-olivar pathways activated by an increase in gravity-inertial force.

This paper, from the aspects of neuroendocrine, emotion, learning etc, analyzed comprehensively the characteristics of the influence of prenatal stress (PS) on offspring, including intensity of PS, timing of exposure and individual differences. Despite the variety in methodology, most studies on it indicate that the prenatal stressful events lead to offspring's increased plasma glucocorticoid (GC) level, more depressed-related behaviors and impaired learning abilities. Although mechanism of prenatal stress is still unclear, most studies show that it is concerned with hypothalamio-pituitary-adneral (HPA) axis,dopaminergic (DA-ergic) system, neuropeptide Y (NPY)and serotoninergic (5-HT ergic) system. Moreover, further studies are proposed to pay more attention to the relationship and interaction of various related substances.

OBJECTIVETo assess the changes of neurobehavioral function in a neonatal mouse model of excitotoxic brain damage.

METHODSFifty-five 5-day-old ICR neonatal mice were randomly assigned to three groups: blank (no intravenous) control (n=20), saline control (n=20) and excitotoxic brain damage model (ibotenic acid treatment, n=15). Behavioral function was evaluated by the surface righting reflex test (postnatal days 6-10), the swimming test (postnatal days 8-12) and the Y-maze discrimination learning test (postnatal days 33-34).

RESULTSRighting time in the surface righting reflex test in the ibotenic acid treatment group on postnatal days 6-10 was more prolonged than that in the two control groups (p<0.05). Swimming test scores in the ibotenic acid treatment group were significantly lower than those in the two control groups (p<0.05). In the Y-maze discrimination learning test, the mice from the ibotenic acid treatment group performed significantly worse than two control groups, presenting with increased learning times (19.79+/-2.42 vs 16.29+/-2.48 or 16.30+/-2.37; p<0.05) and achieving a lower correct percentage (86.7% vs 96.5% or 95.0%) (p<0.05).

CONCLUSIONSThe developmental reflexes and learning and memory functions were impaired in neonatal mice following excitotoxic brain damage. Behavioral testing is useful in the evaluation of early developmental reflexes and long-term neurobehavioral outcome in neonatal mice with excitotoxic brain damage.

The present study aimed to investigate the neuro-cognitive features in the processing of vocabularies of date in Chinese, using block-design functional magnetic resonance imaging (fMRI). Nineteen normal right-handed volunteers whose native language was Chinese performed judgments of vocabulary of month (JVM), the orientation of digit (JOD) and the meaning of words (JMW) respectively, while the fMRI data were recorded by Signa HDe 1.5T MR machine. All design of three tasks was adapted from previous studies with slight modification. The JOD and JWM were investigated as contrast conditions. JVM asked the subjects to determine whether the month belonged to the first half of the year. JOD was to tell whether the third digit had the same orientation (upright orientation or italic orientation) as the first two, and JMW was to determine whether the two-Chinese-character word was animate. The subjects responded according to the task instruction with a button pressing. Statistical parametric mapping (SPM2) was employed to process data and localize functional areas. We compared the average activation intensity of each activated brain regions in the same task against the rest and the activation intensity of the same regions in different tasks respectively. The activations in inferior parietal (BA40) and inferior occipital (BA18/19) were found in the JVM and JOD. The same areas in middle frontal (BA6), fusiform (BA18), posterior in right cerebellum areas were activated during the JVM and JMW. When the activation of the JMW was subtracted from the JVM, many areas concerning numerical processing, such as left anterior cingulate (BA32), post central (BA2), and the right superior temporal (BA39), superior parietal (BA7), as well as the inferior parietal (BA40), precuneus (BA7/19) of the bilateral hemispheres, were significantly activated. When the activation of the JOD was subtracted from the JVM, the left inferior occipital and the fusiform (BA18) of the bilateral hemispheres, which were also involved in the linguistic processing according to previous studies, were significantly activated. The above results prove that the processing of vocabulary of months in Chinese involves not only linguistic processing but also numerical processing; and these results further indicate that Chinese people might gain access to the cognitive experience of number during the process of acquisition of native language.

OBJECTIVETo study the genetic aberrations of ocular extranodal marginal zone B-cell lymphomas of mucosa-associated lymphoid tissue (MALT) type occurring in patients from southern China.

METHODSFifty seven paraffin-embedded ocular MALT lymphoma specimens from patients in southern China were studied by interphase fluorescence-in-situ hybridization (FISH) for genetic aberrations including t(11;18)(q21;q21)/API2-MALT1, t(1;14)(p22;q32)/IgH-bcl-10, t(14;18) (q32;q21)/IgH-MALT1 and bcl-6/FOXP1 gene translocations.

RESULTSAmongst the 57 cases studied, 9 cases (15.8%) showed chromosome translocations, including 4 cases (7.0%) of t(11;18)(q21;q21)/API2-MALT1, 1 case (1.8%) of t(14;18) (q32;q21)/IgH-MALT1, 1 case (1.8%) of bcl-6 gene-related chromosome translocation and 3 cases (5.3%) of IgH-unknown translocation partner. FISH revealed 17 cases (29.8%) with 3 copies of bcl-6 gene, 21 cases (36.8%) with 3 copies of MALT1 gene and 12 cases (21.1%) with 3 copies of both genes.

CONCLUSIONSThe MALT lymphoma-associated chromosome translocations t(11;18)(q21;q21)/API2-MALT1 and t(14;18) (q32;q21)/IgH-MALT1 are demonstrated in ocular MALT lymphomas of southern Chinese patients. The prevalence is significantly different from that reported in northern Chinese and northern American patients, indicating a geographic heterogeneity in the MALT lymphoma-associated genetic aberrations. The presence of 3 copies of bcl-6 and MALT1 genes is the commonest genetic abnormalities observed in ocular MALT lymphomas, suggesting a possible role in MALT lymphomagenesis.

To investigate the mechanisms of a compound (FF16), compatibility of Rhodiola crenulata, Cordyceps militaris, and Rheum palmatum, on glucose metabolic disorders, the IRF mice charactered with insulin resistance and glucose metabolic disorders induced by high-fat diet in C57BL/6J mice were randomly divided into 3 groups; IRF, rosiglitazone (Rosi) and FF16. The glucose metabolism was evaluated by fasting blood glucose (FBG) levels and intraperitoneal glucose tolerance test (IPGTT). The insulin sensitivity was estimated by insulin tolerance test (ITT), fasting serum insulin levels and the index of HOMA-IR. The expressions of Akt and its phosphorylation levels, GSK3beta and its phosphorylation levels in liver were detected by Western Blot. The results showed that FF16 significantly improved the glucose metabolic disorders through reducing FBG by 15.1%, decreasing AUC values in glucose tolerance tests by 22.3%. FF16 significantly improved the insulin sensitivity through decreasing AUC values in insulin tolerance tests by 22.1%, reducing the levels of serum insulin by 42.9% and of HOMA-IR by 49.5%, comparing with model control, respectively. After the treatment with FF16, the levels of p-Akt and p-GSK3beta were increased by 116.4% and 24.9%, respectively, in the liver of IRF mice. In conclusion, compound FF16 could improve glucose metabolic disorders in IRF mice through enhancing the glyconeogenesis.

Previous studies indicated that B7-H4, the youngest B7 family, negatively regulates T cell-mediated immunity and is significantly overexpressed in many human tumors. Tumor stem cells are purported to play a role in tumor renewal and resistance to radiation and chemotherapy. However, the link between B7-H4 and tumor stem cells is unclear. In this study, we investigated B7-H4 expression in the medium of human glioma U251 cell cultures. Immunofluorescence results showed that U251 cells cultured in serum-free medium (supplemented with 2% B27, 20 ng/mL epidermal growth factor, 20 ng/mL basic fibroblast growth factor) maintained stem-like cell characteristics, including expression of stem cell marker CD133 and the neural progenitor cell markers nestin and SOX2. In contrast, U251 cells cultured in serum-containing medium highly expressed differentiation marker glial fibrillary acidic protein. Flow cytometry analysis showed serum-free medium-cultured U251 cells expressed higher intracellular B7-H4 than serum-containing medium-cultured U251 cells (24%-35% vs. 8%-11%, P < 0.001). Immunofluorescence in purified monocytes from normal human peripheral blood mononuclear cells revealed moderate expression of B7-H4 after stimulation with conditioned medium from U251 cells cultured in serum-containing medium. Moreover, conditioned medium from U251 stem-like cells had a significant stimulation effect on B7-H4 expression compared with serum-containing conditioned medium (P < 0.01). Negative costimulatory molecule B7-H4 was preferentially expressed in U251 stem-like cells, and conditioned medium from these cells more effectively induced monocytes to express B7-H4 than conditioned medium from U251 cells cultured in the presence of serum. Our results show that U251 stem-like cells may play a more crucial role in tumor immunoloregulation with high expression of B7-H4.
