Using PCR technique, the vp3 gene of chicken anemia virus (CAV) was cloned into the eukaryotic expression vector pcDNA3 to construct a recombinant pcDNA-vp3. Restriction enzyme digestion and sequencing analysis revealed that CAV vp3 gene was correctly inserted into the blank vector pcDNA3. After LipofectAMINE-mediated transfection in vitro with pcDNA-vp3 and pcDNA3 respectively, the total mRNA was extracted from liver carcinoma cell lines HepG2 and diploid cell line L-02, and RT-PCR was performed afterward. The results of RT-PCR suggested that vp3 gene was expressed in these two cell lines. At the same time, using in situ apoptotic detection assay, TUNEL kits, the apoptotic cells were found in pcDNA-vp3 transfected HepG2, but not in mock transfected cell lines. VP3 could induce cell death by apoptosis in cancer cell lines, but not in diploid cell lines. All the results indicated that CAV vp3 gene, a potential therapeutic agents, has the potential of being used for cancer treatment.

In order to construct a single chain fragment variable (ScFv) phage display library against ovarian tumor, by using RT-PCR, the human heavy chain variable region genes (VH) and light chain variable region genes (VL) were amplified from lymphocytes of ovarian tumor patients and subsequently assembled into ScFv genes by SOE. The resulting ScFv genes were electrotransformed into E. coli TG1 and amplified with the co-infection of helper phage M13KO7 to obtain phage display library. The capacity and titer of the resulting library were detected. The phage antibody library with a capacity of approximately 3 x 10(9) cfu/microg was obtained. After amplification with helper phage, the titer of antibody library reached 5 x 10(12) cfu/mL. Human ScFv library against ovarian tumor was constructed successfully, which laid a foundation for the screening of ovarian tumor specific ScFv for the radioimmunoimaging diagnosis of ovarian tumor.

ObjectiveTo observe the clinical efficacy of relaxing needling plus joint needling from the Internal Medicine in treating post-stroke spastic hemiplegia.MethodTotally 121 eligible subjects were randomized intoan ordinary acupuncture group (61 cases) and a relaxing-joint needling group (60 cases). The two groups were treated for 2 weeks, 5 sessions each week. The spasm of the lower limb was evaluated by using Fugl-Meyer Assessment Scale (FMA), modified AshworthScale (MAS), Tardieu Scale, and Activities of Daily Living (ADL) before and after treatment. Besides, 4 patients from each group were randomly selected for the three-dimensional gait analysis, and the dorsi-extension, range of motion (ROM) of ankle, strephenopodia, and heel-raising height were observed.Result and ConclusionRelaxing-joint needling and ordinary acupuncture both can produce significant efficacies in treating post-stroke spastic hemiplegia. The relaxing-joint needling produced more significant efficacies in improving the body balance, ROM, muscular tension, and lower limb spasticity compared to ordinary acupuncture. It’s plausible that relaxing-joint needling improves the strephenopodia and hemiplagia gait through renovating body balance, ROM, muscular tension, and lower limb spasticity. Since the three-dimensional gait analysis can analyze the dorsi-extension, strephenopodia, and heel-raising height, thus it can be used to evaluate the change of the spastic gait of post-stroke hemiplegia in amore objective, elaborate, and correct way.

Purpose To investigate the expression of tumor buds and its relationship with clinicopathological characteristics in endome-trial carcinoma. Methods 47 cases of endometrial carcinoma were observed and analyzed by means of clinicopathologic data and im-munohistochemical staining. The connections between tumor buds and clinicopathologic parameters were studied by statistics. Results Of the 47 endometrial carcinoma cases, tumor buds were seen in 18 cases. Tumor buds were correlated with histological grade, lymph node metastases, vascular invasion, Ki-67 index and survival. There were no associations between tumor buds with age, tumor size, pTNM stage or myometrial invasion depth. Immunohistochemistry demonstrated that the level of N-cadherin, vimentin in bud cells was higher than normal carcinoma cells while the level of CK(AE1/AE3),β-catenin and E-cadherin got the opposite results. Conclu-sion Tumor buds may play an important role in the progression of endometrial carcinoma. The immunohistochemical features of bud cells indicated that tumor buds may be a key step in epithelial-mesenchymal transition.

Objective To express protein transduction domain (PTD)-deletion proline domain (ΔPRD) Foxp3 fusion protein, and to analyze its influence on mixed lymphocyte reaction in mice.Methods We cloned mouse ΔPRD of Foxp3 gene by PCR, and inserted it into pET28a-PTD, pET28a-PTD-eGFP vector, then expressed fusion proteins in E.coli Rosetta (DE3). The fusion proteins were purified and refolded by Profinity IMAC Ni~(2+)-Charged Resin. The expression of fusion proteins was identified by Western blot. Flow cytometry assay was used to detect the effect of PTD-ΔPRD fusion protein to transduce into mouse EL-4 cells. The ability of fusion protein to inhibit the proliferation of EL-4 cells was analyzed by two-way mixed lymphocyte reaction.Results The PTD-ΔPRD fusion proteins were expressed and purified efficiently. Western blot and flow cytometry indicated that PTD-ΔPRD fusion protein was transduced into EL-4 efficiently. Mixed lympocyte reaction assay showed that PTD-ΔPRD fusion protein had the bioactivity to inhibit the proliferation of EL-4 cells.Conclusion The PTD-ΔPRD fusion protein was expressed in E.coli system and could be transduced into cells effectively, suggesting that PTD-ΔPRD fusion protein may be an inhibitor in lymphocytes from mouse spleen.
