Purpose To investigate clinicopathological features,diagnosis and differential diagnosis of tubular carcinoma of the breast.Methods Morphological observation and immunohistochemistry were applied in 29 cases of tubular carcinoma of the breast, and the literatures were also reviewed.Results The tumors were composed of open tubules, infiltrating haphazardly in the cellular desmoplastic stroma. The neoplastic tubules were enclosed by a single layer of epithelial cells with insignificant atypia or rare mitoses.The tumors were often associated with lobular neoplasm, columnar cell lesion, ductal atypical hyperplasia or carcinoma in situ. Immunostaining displayed that myoepithelial cells were absent or incomplete.Conclusions Tubular carcinoma of the breast is a peculiar subtype of breast carcinoma with good prognoses, which is easily confused with microglandular adenosis, radial sclerosing lesions,or low grade invasive ductal carcinoma.Immunohistochemistry is useful for the differential diagnosis.

Objective To construct anti-IL-4R murine anti-human single-chain variable fragment (scFvs) antibodies through BL21 (DE3) prokaryotic expression system. Methods The anti-IL-4R scFv sequence was optimizated on the basis of previous findings. The optimized scFv sequence was analyzed. The recombinant plasmid pET-32a-scFv was constructed. The recombinant plasmid was detected through enzyme identification, and was turned into BL21 (DE3) prokaryotic expression bacteria to express the pET-32a-scFv recombinant protein in E.coli BL21 (DE3). The purification and renaturation were researched, and SDS-PAGE analysis was studied. The molecular weight of ScFv against IL-4R was analyzed by SDS-PAGE. The expression of the fusion protein was detected by Western-blot assay. Results The length of fusion gene scFv-MLT sequence was 761 bp. The molecular weight of the recombinant expression of proteins of anti-IL-4R single antibody was approximately 45 ku. The recombinant proteins showed high specificity with anti-6 × His-tag antibody. Conclusion This experiment successfully constructs pET-32a-scFv prokaryotic expression system of recombinant protein with high immune reactivity, which provides the basis for further study of anti-IL-4R single chain antibody as drug target.

Objective To evaluate the safety and efficacy of the temporary bedside cardiac pacing in controlling torsades de points (TdP) in patients with acquired long QT syndrome (LQTS). Methods Twelve patients with acquired LQTS were enrolled from April 2003 to August 2007 consecutively and their clinical data were analyzed. Bedside cardiac pacing was adopted when other methods couldn't terminate the repeated TdP. Results Twelve patients successfully experienced the temporary bedside cardiac pacing via femoral venous. The average time spent in bedside cardiac pacing was about (10.5±2.4) min. After cardiac pacing the interval of QT and QTc were shortened [ (0.42±0.03 ) svs (0.52±0.06) s, P < 0.05; (0.43± 0.04 ) s vs (0.53±0.05 ) s, P <0.05 ]. The TdP occurred (4.6±1.2 ) times per day before cardiac pacing and it didn't reoccur any more after bedside cardiac pacing. The average time for cardiac pacing was(3.8±1.4) d. When the patients were discharged, the interval of QT and QTe were (0.41±0.02) s and (0.42±0.05) s respectively, there were significant differences compared with that before cardiac pacing(P< 0.05). During 1 year follow-up, the patients didn't experience TdP any more, and the interval of QT and QTe were (0.41± 0.06) s and (0.42±0.05) s respectively. Conclusion The immediate bedside cardiac pacing is a safe and effective way to control the repeated TdP.

Objective To assess the efficiency and safety of mycophenolate mofetil (MMF) in patients with multiple sclerosis (MS) and neuromyelitis optica (NMO). Methods Twenty-seven patients with MS or NMO were selected, and the patients were divided into 2 groups:MMF group (MMF combined with glucocorticoid treatment group, 10 cases) and glucocorticoid group (only glucocorticoid treatment group, 17 cases). There were 5 cases with MS and 5 cases with NMO in MMF group. There were 13 cases with MS and 4 cases with NMO in glucocorticoid group. The therapeutic efficacy 6 months after treatment, expanded disability status scale (EDSS) before treatment and 6 months after treatment, and annualized relapse rate (ARR) were compared; and the safety was observed. Results There was no statistical difference in efficacy rate 6 months after treatment between MMF group and glucocorticoid group: 9/10 vs. 11/17, P>0.05. The EDSS scores 6 months after treatment in MMF group and glucocorticoid group were significantly lower than those before treatment: (2.41 ± 2.05) scores vs. (3.40 ± 2.05) scores and (1.17 ± 0.92) scores vs. (2.38 ± 1.28) scores, and there were statistical differences (P<0.05), particularly for the patients with MS. The ARR 6 months after treatment in MMF group was significantly lower than that before treatment: 0 time/year vs. 0.75 times/year, and there was statistical difference (P<0.05). The difference of ARR before and after treatment in MMF group was significantly higher than that in glucocorticoid group: 0.75 times/year vs.- 0.46 times/year, and there was statistical difference (P<0.01), particularly for the patients with MS. Only 1 female patient had myalgia when taking higher dosage of MMF, and the symptom tended to relieve after the dosage was reduced. Conclusions MMF is effective in the treatment of MS and NMO. MS can improve the neurological function and reduce the recurrence of the disease;and the safety is high.
