Objective Our aim was to observe the effects of prenatal nicotine exposure on development of cerebral cortex and hippocampus in the offsprings of pregnant mice and expressions of NCAM proteins. Methods We established prenatally nicotine exposed(PNE) animal models.We investigated the offspring's structural changes of cerebral cortex and hippocampus with HE staining.Using immunohistochemistry and Western blotting we observed the changes of expressions of NCAM proteins in the neonatal mice. Results Cerebral cortex and hippocampus as well as hippocampal cell layers of the PNE offsprings were thinner than that of the control group.The expressions of PSA-NCAM in cerebral cortex and hippocampus of the PNE offsprings were higher than the control group while the expressions of NCAM-180,140 and 120 weaker.Conclusion Prenatally nicotine exposure can prevent normal morphogenesis of cerebral cortex and hippocampus of mice and can change the expressions of NCAM proteins in cerebral cortex and hippocampus of neonatal mice.

Objective: Our aim was to evaluate the biocompability of porcelain compounded with nanostructured material. Methods：The proliferation of the NIH3T3 cells were investigated using a tetrazolium-based colorimetric assay(MTT assay).Maceration extract of four tested materials were added into culture plate .The samples were tested with ultraviolet spectrophotometer in 490 wavelength at 1，3，5，7 days after the addition of extract. Morphology of these cells was also observed with phase-contrast microscope. Results： There was no obvious difference among three kinds of prosthetic materials in the optical absorbance and the cells growing in the extract showed normal morphology. Conclusion: The toxicity graduation of the porcelain compounded with nanostructured material is 0. This material has a good biocompability and can be used clinically.

Objective To study the diagnostic value of high-frequency color Doppler ultrasound (CDU) on the obstruction of proximal deferent duct. Methods One hundred and twenty-three patients with scrotal diseases (aged 23-67 years old) were examined by CDU with 5-10 MHz transducer. Among the cases, infertility was in 88, vasoligation in 8, and epididymal nodes in 27. The sonographic appearances of the obstruction of the deferent duct were analysed, compared with that of normal deferent duct. Results Of the 123 cases, the obstruction of the deferent duct was in 72, included absence of deferent duct in 6, epididymal malformation in 9, epididymitis in 37, epididymal neoplasms in 5, and dilatation of testic rete and testic efferent duct in 3. Twenty-two patients underwent surgery, confirmed the sonographic appearances of the obstruction of proximal deferent duct. Conclusions Obstruction of proximal deferent duct could be assessed by high-frequency CDU. It is helpful for distinguishing the causes of the obstruction of proximal deferent duct and choosing their therapy scheme.

0.05). CO decreased at T2, T3, T4 and T5 compared with that at T0 in both groups (P

Objective To examine clusters of anti-nuclear antibodies (ANA) and their associations with clinical features in patients with systemic lupus erythematosus (SLE).Methods It was a retrospective study.113 SLE patients were reviewed from March 2010 to May 2012 in Department of Rheumatology,Jinhua Central Hospital.ANA and specific autoantibodies to 15 kinds of nuclear antigens were tested by indirect immunofluorescence assay (IIF) and line immunoassay (LIA) respectively.Hierarchical clustering method was performed to analyze specific clusters of ANA profiles in SLE.Chi-square tests were used to investigate relationship between antibody clusters and clinical features of SLE.Results The positive rate of LIA for ANA was 97.3％,consistent with IIF method,and the total accordance rate of the both methods was 98.2％.Thirteen kinds of antigen-specific antibodies were detected in SLE patients by LIA.Clustering analysis for these antibodies showed three specific clusters in SLE,Nuc/His/dsDNA cluster (C1),low-Ro/low-La cluster (C2),and Ro/Sm/RNP cluster (C3),accounting for 36.3％,24.8％,38.9％ of the total cases respectively.There were significant difference of AST levels among three clusters [(32.62 ± 21.92)U/L,(25.56 ± 16.63) U/L,(50.41 ± 60.86) U/L respectively for C1,C2 and C3].High incidences of chronic cutaneous lupus,abnormal renal indicators and inflammatory synovitis were found in all three clusters.Besides,there were significant differences among three clusters for the incidences of chronic cutaneous lupus (39.0％,39.3％,63.6％ respectively for C1,C2,C3) and leukopenia/lymphopenia (56.1％,25.0％,56.8％ respectively for C1,C2,C3) (P ＜ 0.05).Patients in Ro/Sm/RNP cluster showed higher incidences of lupus nephritis (43.2％/26.8％ or 39.3％); patients in low-Ro/low-La cluster showed low risk of hypertension (7.1％/19.5％ or 22.7％) ; patients in Nuc/His/dsDNA cluster showed high incidences of thrombocytopenia (41.5％/21.4％ or 25.0％) and high risk of lung or upper respiratory tract infection (46.3％/28.6％ or 29.5％),but low incidence of neurologic symptoms (0％/ 3.6％ ％ or 11.4％).Conclusion Three characterized ANA clusters are identified in SLE patients in this pilot study.Different clusters are associated with certain clinical features and complications ofSLE.However,the correlations found in this study need to be investigated further in larger populations.

OBJECTIVE: To study the effect of Jianpi Huoxue Jiedu (JPHXJD) prescription on prevention of the postoperative metastasis of gastric cancer and to observe the changes of immunity and whole blood viscosity after treatment. METHODS: JPHXJD prescription and chemotherapy were administered to the treated group for 12 successive months, while only chemotherapy was given to the control group. RESULTS: The effective rate of anti-metastasis in the treated group was obviously better than that in the control group. In the aspects of enhancing Karnofsky scores, reducing whole blood viscosity and improving immunity after treatment, the treated group was better than the control group (P<0.05). CONCLUSION: JPHXJD prescription combined with chemotherapy shows apparent effect on anti-metastasis. It can improve the quality of life of the patients, lower the whole blood viscosity and improve the immunity function.

Objective To study the expression and the distribution of Tropic 1808 gene expressional protein in the lesioned sciatic nerves of adult SD rats. Methods Both distal and proximal segments of 12 days cut-off sciatic nerves of SD rats were obtained.Then immunohistochemistry and dual fluorescent-immunohistochemistry were performed to observe the expression of Tropic 1808 gene expressional protein in the lesioned sciatic nerves.The positive intensity and area of immuno-response were detected by the image analyses system. Results The Schwann cells's membranes which in the distal and proximal of lesioned sciatic nerves appeared to have positive expression of Tropic 1808 gene expressional protein.The positive intensity and area of immuno-response in the distal end were denser and larger than those in the proximal.Conclusion Tropic1808 gene expressional protein expresses in the Schwann cell's membranes of the distal and the proximal after the peripheral nerves were injured.The positive expression in the distal was higher than that in the proximal.;

Objective To study the reconstructive treatment of the different types of neurofibroma and neurofibromatosis in different locations. Methods 37 patients with neurobibroma or neurofibromatosis were reviewed, including 8 cases with simple suture after excision, 9 cases with skin grafting in situ, 12 cases with skin flap grafting. The main points of the treating methods for different types of neurofibroma and neurofibromatosis were discussed, and the chief clinical manifestations, therapeutic principle and notices of the operation were then summarized.Results These 37 patients, including 25 cases of neurofibroma, 11 cases of neurofibromatosis typeⅠ and 1 case of neurofibromatosis type Ⅱ, were satisfied with the results after reconstructive operation. Conclusion The methods of reconstructive operation of neurofibroma and neurofibromatosis, such as simple suture after excision, skin grafting in situ, skin flap grafting, the use of skin soft tissue expansion, microskin grafting and so on, must be selected according to the different type and location of the neurofibroma and neurofibromatosis. The reconstructive operation must guarantee the best recovery of the visage and the function on the basis of the most degree of tumor excision.
