Autophagy dysregulation, mitochondrial dynamic abnormality and cell cycle re-entry are implicated in the vulnerable neurons of patients with Alzheimer's disease. This study was designed to testify the association among autophagy, mitochondrial dynamics and cell cycle in dividing neuroblastoma (N2a) cells. The N2a cells were cultured in vitro and treated with different concentrations of 3-methyladenine (3-MA). The cell viability was detected by methyl thiazolyl tetrazolium (MTT) assay. They were randomly divided into control group (cells cultured in normal culture medium) and 3-MA group (cells treated with 10 mmol/L 3-MA). The cell cycle was analyzed in the two groups 3, 6, 12, and 24 h after treatment by flow cytometry. Western blotting was used to evaluate the expression levels of mitofission 1 (Fis1), mitofusin 2 (Mfn2), microtubule-associated protein 1 light chain 3 (LC3), cell cycle-dependent kinase 4 (CDK4) and cdc2. The flow cytometry revealed that the proportion of cells in G(2)/M was significantly increased, and that in G0/G1 was significantly reduced in the 3-MA group as compared with the control group. Western blotting showed that the expression levels of Fis1, LC3, and CDK4 were significantly up-regulated in the 3-MA group at the four indicated time points as compared with the control group. Mfn2 was initially decreased in the 3-MA group, and then significantly increased at 6 h or 12 h. Cdc2 was significantly increased in the 3-MA group at 3 h and 6 h, and then dropped significantly at 12 h and 24 h. Our data indicated that 3-MA-induced suppressed autophagy may interfere with the cell cycle progression and mitochondrial dynamics, and cause cell death. There are interactions among cell cycle, mitochondrial dynamics and autophagy in neurons.

An iodine analysis instrument with sequential injection of urine samples was developed. A method for measurement of urine iodine was also developed by combining sequential injection and catalysis kinetics,and making use of catalysis facilitation of the iodine in the redox reaction of As~(3+) and Ce~(4+) . The sequential injection and stopped-flow stabilization determination were made possible by the program-controlled injector with controlled flow rate and the 16-hole program-controlled selection valves. The arsenic-cerium reaction with iodine-catalyzed at constant temperature state might proceed with the constant temperature flow cell. Using the syringes with program-controlled velocity,pushing and suction,Using the digital connected circuit and micro-iodine determination software,the reaction temperature of (32.0±0.1)℃,injection time of 45 s,stabilization time of 60 s,detection time of 20 s,injection volume of 400μL,linear range of 15 -600μg/L,detecting limitation of 5.01 μg/L(n=11) and recovery rate of 94. 1 % - 105. 1 % were obtained. With this method,the detecting result of the National Standard Reference (GBW09109 and GBW09110) materials was within a given standard range. Through this method,the detecting results had no significant differences comparing with those by standard method of National Health Service(P >0.05).

ObjectiveTo investigate the expression of Snail in bladder urothelial carcinoma and evaluate its relationship with E-cadherin and a subset of T cell groups.MethodsImmunohistochemical method was used to detect the expression of Snail and E-cadherin proteins in tissue from 156 cases of bladder urothelial carcinoma and 80 cases of the para-cancerous mucosa. The proteins expression status was analyzed with clinico-pathological data. Meanwhile, correlations with Snail and CD4+, CD8+, CD4+/CD8+ were analyzed.ResultsThe positive rate of Snail in bladder urothelial carcinoma was 65.4％ , which was significantly higher than that in para-cancerous mucosa (48.8％). The expression of Snail was significantly correlated with the clinical stage, pathological grade, tumor quantity, distant metastasis and tumor recurrence.There was negative correlation between the expression of Snail and E-cadherin in bladder urothelial carcinoma. Positive expression of Snail had a negative correlation with the number of CD4+ and CD4+/CD8+ , whereas it had no significant correlation with the number of CD8+.ConclusionsBy inhibition of the E-cadherin expression and inducing local immunosuppression, Snail might play an important role in the process of the invasion and metastasis of bladder urothelial carcinoma.

Objective To study the clinical characteristics of bulbar myasthenia gravis (MG). Methods Retrospective review was performed on 166 patients with bulbar type of myasthenia gravis, diagnosed at Tongji Hospital in the period of May 1983 through October 2005.Results Bulbar MG was a relatively rare type of MG,accounting for 5.7% (166/2888) of MG classifications.Females were more often affected than males (the ratio of male:female was 1:1.35).The peak of onset age was at 20—40 years.The incidence of myasthenia crisis in the group was 26.5% (44/166).Myasthenic crisis occurred in 10.8% (18/166) of the bulbar MG patients within 6 months after onset,resulting in a mortality rate of 6.0% (10/166) in the group.Out of the group,30 cases experienced puhnonary infections (18.1%). Thirty cases were initially misdiagnosed as other diseases such as nasopharyngeal disorders (33/166, 19.9%).The routine therapy was not very satisfactory.Median dose cyclophosphamide therapy appeared to be effective for ameliorating refractory MG.Thymectomy was performed in 25 patients,with optimistic efficacy rate up to 80.0% (20/25) in a 3-year follow-up.Conclusions The clinical analysis in the current study suggested that the bulbar MG had its own characteristics in such aspects as progression of the disease, complications,treatment and prognosis.The information of the clinical manifestations presented in this study may be useful in diagnosing and treating bulbar MG.
