Mucosal adjuvants play important roles in vaccine development. By now, the common used mucosal adjuvants can be divided into three categories: the bacterial derivatives, cytokines and chemokines, and antigen delivery systems. Progresses of the three kinds of adjuvants were reviewed to give a reference to novel vaccine research.

Objective To investigate the effects of different concentrations of propofol on the apoptosis in hippocampal neurons in neonatal rats in vitro.Methods Primary hippocampal neurons were prepared from newborn Sprague-Dawley rats (aged 7 days) and cultured for 7 days.The neurons were randomly divided into 7 groups (n =8 each):control group (group C),propofol 4,8 and 12 μg/ml groups (groups P1-3),and fat emulsion 4,8and 12 μg/ml groups (groups F1-3).The cells were cultured for 24 h in the culture medium containing propofol 4,8 and 12μg/ml in groups P1-3,respectively.The cells were cultured for 24 h in the culture medium containing fat emulsion 4,8 and 12 μg/ml in groups F1 3,respectively.The cell morphology was examined by microscopy after 24 h culture.The expression of caspase-3 (by immuno-histochemistry) and neuronal apoptosis were detected.The neuronal apoptosis rate was calculated.Results Compared with group C,the neuronal apoptosis rate and caspase3 expression were significantly increased in groups P1-3 (P ＜ 0.05 or 0.01).The neuronal apoptosis rat and caspase-3 expression were increased in a concentration-dependent manner in groups P1-3 (P ＜ 0.05).The neuronal apoptosis rate and caspase-3 expression were significantly lower in groups F1-3 than in groups P1-3 (P ＜ 0.05).There was no significant difference in the neuronal apoptosis rate and caspase-3 expression between groups F1-3 (P ＞ 0.05).The damage to neurons was induced in groups P1-3 and most severe in group P3.Conclusion Propofol can promote the apoptosis in hippocampal neurons in neonatal rats in vitro in a concentration-dependent manner.

Treatment options of retinoblastoma should be individualized. Patients with early intraocular stage may be managed with focal treatments, including cryotherapy, thermotherapy, laser photocoagulation, brachytherapy and so on. Patients with middle in- traocular stage may be treated with chemoreduction plus focal therapy. In patients with advanced stage, enucleation and chemotherapy are recommended, with the addition of orbital radiation for patients with extraocular retinoblastoma. Patients with systemic metastases require intensive chemotherapy and consolidation with autologous hematopoietic stem cell rescue.

Objective To describe the work of quality control for lipids measurement in CNHS 2002.Methods The quality control was applied over the whole project including staff training,making standard operating procedure(blood collection,separation,temporary storage,transportation,final storage),lab materials assignment,internal quality control in central lab and participating US Disease Control Center's Lipids Standard Program(LSP)as external quality control.Results Seven times of national training programs were held and 326 technicians from CDCs in 31 provinces,autonomous regions, municiplalities and 132 surveyed counties received related trainings.During the program,321 persons passed examination (98.5%)and among them 205 got the A score(62.9%);The field work was implemented strictly according to the procedure. Three automatic biochemical instruments were used in the measurement and there is no significant difference between means of serum TC,TG and HDL-C from several batches of quality control serum.Parallel measurements were conducted in five percent randomly selected samples,the ratio of bias less than 3% was 99.05%,96.40% and 98.30% for TC,TG and HLD-C, respectively.Compared with means of LSP control sera,the results showed that all bias was less than 5% except one bias of TG result(7.02%)in one batch of LSP controls.Conclusion The work of quality control in this survey guaranteed the accuracy of plasma lipids measurement,and provided the basic data for the epidemiological description of dyslipidemia status among Chinese and the further analysis.

OBJECTIVE:To provide references for the evolvement of Chinese drug safety credit system construction.METHODS:The status quo of Chinese drug safety credit system was analyzed by applying the credit management theory,and some corresponding developmental countermeasures were put forward by drawing experiences from abroad.RESULTS &CONCLUSION:The fundamental strategy for the construction of standardized economic order in pharmaceutical market is to establish and perfect drug safety credit system.The drug safety credit system should be constructed comprehensively from the credit laws,credit information databank,credit ratings,credit supervision,credit agency,credit awards and punishments,etc.

Objective To study the expressions of S100B and glial fibrillary acidic protein(GFAP) in the central nervous system of Sprague-Dawley rats during postnatal development. Methods Twenty-four male SD rats were divided equally into four groups according to different postnatal times:7-day group,14-day group,21-day group and adult group.Immunohistochemistry was used to investigate the expressions of S100B protein and GFAP in the brain and the spinal cord. Results The amount and density of S100B positive astrocytes decreased significantly in frontal cortex,hippocampus,striatum,substantia nigra and spinal cord during postnatal development.It seemed that the second through the third week after birth was a critical period for these changes.The amount and density of GFAP positive AST increased gradually in the brain,but it was the opposite in the spinal cord.Double-labeled immunofluorescence of S100B and GFAP in hippocampus CA1 area showed that S100B positive stains were evenly distributed in the pyramidal,polymorphic and molecular layers from the seventh till the twenty first day after birth,but apparently decreased in each layer especially in the molecular layer in adult hippocampus while the immunoreactivities of GFAP increased.The proportion of double labeled cells also increased with the aging and more of them were found in the pyramidal and polymorphic layers.Conclusion Different patterns of the expressions of S100B and GFAP exist during postnatal development.It may reflect the different roles of these proteins on the glial cell development.And it may also indicate that the expressions of S100B and GFAP are regulated by different mechanisms during the course of development,which reflects the differentiation of subpopulations of astrocytes during ontogenesis.

Objective To analyze the clinical features and its influencing factors of depression pa?tients with and without psychotic symptoms. Methods According to the presence of psychotic symptoms, 374 patients with major depression were divided into psychotic major depression ( PMD group,79 case) and nonpsychotic major depression ( NMD group,268 case) . All patients completed social demographic question?naire ( including gender,age,marital status,educational level,family history,positive family history of psychi?atric disorder,disease onset age,frequency of attack,times of hospitalization,etc.) and Hamilton's depression scale (HAMD?24). Results Positive family history(PMD group 47/79,NMD group 104/268, P<0.01), psychiatric disorder positive family history(PMD group 19/79,NMD group 26/268, P<0.01) and times of hospitalization(PMD group(2.52±1.29),NMD group(1.39±1.31), P<0.01) in the PMD group were signifi?cantly higher than the NMD group.HAMD total scores(PMD total score(47.85±8.69),NMD total score (43.44±8.51), P<0.01),the factor score of anxiety/somatization(PMD group(11.40±3.28),NMD group (9.19±3.54), P<0.01) and cognitive impairment(PMD group(12.24±3.77),NMD group(9.45±3.68), P<0.01) in the PMD group were significantly higher than the NMD group.Disease onset age(PMD group(30.09 ±5.17),NMD group(35.95±9.06), P<0.01),the course of the disease(PMD group(1.58±0.76),NMD group(3.02±2.87), P<0.01),the factor score of day and night change(PMD group(0.76±0.46),NMD group(1.01±0.51), P<0.01) in PMD group were significantly lower than the NMD. Logistic regression anal?ysis showed the major depression with positive family history of mental disorders( β=3.278) ,attack in early age( β=-2.524),seriously cognitive dysfunction in patients( β=3.836) may indicate the psychotic symp? toms( P<0.05).Conclusion PMD patients more positive family history,psychiatric disorder positive family history,likely to be hospitalization,severe symptoms and attack in early age compared with NMD. With posi?tive family history of mental disorders,attack in early age,seriously cognitive dysfunction in patients with ma?jor depression may indicate the psychotic symptoms.
