Objective To evaluate the expression of Yes-associated protein (YAP) in colorectal carcinoma and analyze its influence on tumor cell proliferation.Methods The expressions of YAP in 94paired colorectal carcinomas and pericancerous normal tissues were detected by using immunohistochemistry method.The expressions of YAP in colorectal carcinoma cell line HCT116 were inhibited with a YAP-spe-cific siRNA.Cell proliferation was then determined by methyl thiazolyl diphenyl-tetrazolium bromide (MTT) assay.Results The positive rate of YAP in colorectal carcinomas was significantly higher than that in pericancerous normal tissues [69.1％ (65/94) vs 22.3 ％ (21/94),P ＜ 0.001].The expression of YAP was associated with tumor Node Metastasis(TNM) stage and lymph node metastasis(P ＜0.05),but not associated with gender,age,tumor location and histological grade(P ＞0.05).After YAP-specific siR-NA was transfected into HCT116 using lipofectamine,the expression of YAP mRNA and protein in the experimental group were reduced by (78.2 ±2.1)％ and (81.7 ± 1.5)％,respectively,with a statistically significant difference (t =67.55,91.601,P ＜0.01).The growth of HCT116 was significantly inhibited and the reduced rate of cell proliferation was (28.1 ± 1.6) ％,(34.7 ± 2.4) ％ and (24.7 ± 1.2) ％ at the time point of 48 h,72 h and 96 h,respectively.Conclusions Expression of YAP was upregulated in colorectal carcinomas and downregulation of YAP expression could inhibit growth of colorectal carcinoma cells.YAP can be used as a new candidate target for diagnosis and treatment of a colorectal carcinoma.

Objective To evaluate the therapeutic efficacy of endovascular embolism in treating aneurysms located at the bifurcation of middle cerebral artery. Methods During the period from Jan. 2009 to May 2013 at authors’ hospital, a total of 21 patients with intracranial aneurysms located at the bifurcation of middle cerebral artery were treated with interventional embolization. Of the 21 cases , steel coils were used in 7, stent-assistant embolization was adopted in 12, and dual-microcatheter technique was employed in 2. The results were analyzed. Results Postoperative angiography showed that complete embolization of the aneurysm was achieved in 14 patients, residual neck was detected in 2 patients and subtotal obliteration of the aneurysm was seen in 5 patients. Procedure-related complications occurred in 2 patients, including cerebral bleeding during operation (n = 1) and postoperative small area cerebral infarction. Seventeen patients were followed up for 6 months, and follow-up angiography showed that no recurrence of aneurysm was seen. Conclusion For un-ruptured, or ruptured with no big hematoma, intracranial aneurysms located at the bifurcation of middle cerebral artery, endovascular interventional embolization is the treatment of choice.

Objective To discuss the feasibility and effect of labeled antibody on targeting therapy of systemic lupus erythematosus(SLE) associated thrombocytopenia.Methods MTX-IVIG conjugate was prepared by indirect and direct cross linking,and the binding ability of it to Fc fragment was detected by indirect immunofluor-escence.The killing activity of the conjugate was detected by MTT method using murine macrophage with Fc receptor and strain U937 of human monocytic leukemia cell as targets.Results Conjugation showed stronger cytotoxicity upon target cells than free MTX,and it showed less cytotoxic effect on Fc receptor negative cells compared with the positive ones.IVIG-HSA-MTX restrained the phagocyte of macrophage.The killing effect of IVIG-HSA-MTX was significantly stronger than that of IVIG-MTX.Conclusion The conjugation can show a highly specific cytotoxicity upon mononuclear-macrophage in vitro.

Objective:To study the effects of several herbal medicines on SMMC-7721 liver cancer cells with Fourier transform infrared spectrometer(FTIR). Methods: FTIR was employed to determine the infrared spectra(IRs) of SMMC-7721 liver cancer cells cultivated for 20 h with the extracts of Spica prunellae, Herba houttuyniae, Radix bupleuri and Herba artemisiae scopariae. Cluster analysis of IRs was also performed. Results: IR spectral parameters such as band shape, intensity and frequency of the blank, control and herbal-extract-treated cells were compared. There existed obvious blue shift of ? s(PO 2 -), ? as (PO 2 -) bands, red shift of ? as (CH 3), ?(CH 2) bands on the herbal-extract-treated cells IRs. The decreasing ratio of ? as (CH 3) to ? s(CH 2) peak intensity and the increasing ratio of ? s(PO 2 -) to ?(N-H) peak area indicated the destructive effect of herbal extracts on the membrane structure of SMMU-7721 cells and inhibitory effect on the DNA replication respectively. Cluster analysis successfully discriminated the herbal-extract-treated cells from the blank cells and the liver-oriented medicines from the non-liver-oriented medicine. Conclusion: FTIR provides another fast and effective approach to analyze the changes of cells treated with Chinese herbal medicines, which may help to illuminate the functional mechanism of Chinese herbal medicines.

Objective To compare the effects of BOSU ball exercise and treadmill walking on lower limbs function in patients after stroke. Methods 40 patients more than 6 months after stroke were randomly divided into BOSU ball group (n=20) and treadmill group (n=20), who accepted BOSU ball or treadmill exercise on the basis of routine rehabilitation. They were assessed with Berg Balance Scale (BBS), 30-s chair stand (CS-30), sit and reach (SR), 6 minutes walk test (6MWT) and modified Barthel Index (MBI) before and 12 weeks after treatment. Results The scores of all the assessment improved in both groups after treatment (P<0.05), and the socres of BBS and MBI improved more in the BOSU ball group than in the treadmill group (P<0.05). Conclusion BOSU ball exercise can improve more of the balance and activities of daily living in post-stroke patient than treadmill walking.

Objective To investigate the diagnostic value of CT-guided craniocerebral puncture biopsy, and to discuss its clinical safety. Methods During the period from April 2013 to June 2014 at authors’ hospital CT-guided craniocerebral puncture biopsy was carried out in 23 patients. All patients had clinical symptoms or signs of nervous system. Imaging examination revealed that all patients had intracranial space-occupying lesions. CT-guided craniocerebral puncture biopsy was performed to make pathological or bacteriological examinations. The results were statistically analyzed. Results In this group of patients, definite pathological diagnosis was made in 19 cases, biopsy positive diagnosis rate of biopsy was 82.6% (19/23), among them oncology-pathological diagnosis was obtained in 14 cases (60.9%), mainly including glioma, non-Hodgkin lymphoma, dysembryoplastic neuroepithelial tumor, choroid plexus papillary tumor, epidermoid cyst, etc. Non-neoplastic lesion was confirmed in 5 cases (21.7%), including suppurated meningitis, cerebral gliosis hyperplasia, cerebral telangiectasis, etc. Small amount of subdural hemorrhage was observed in one case (4.3%). No severe complications, such as intracranial infection or epilepsy, occurred in all patients. Conclusion CT-guided craniocerebral puncture biopsy is minimally-invasive with fewer complications, it can provide definite diagnosis for intracranial lesions, therefore, this technique has a broad development prospect in clinical practice.

Objective To explore the influence of the lentiviral vectors-mediated mouse genetic engineering regulatory T cells (Treg) infused after allogeneie bone marrow transplantation (allo-BMT)on graft-versus-host disease (GVHD) in mice.Methods Lentivirus-mediated expression of Forkhead box P3 (Foxp3) converted CD4~+ CD25~- T cells from Balb/c mice into engineered Tregs in vitro.An allo-BMT model of Balb/c→C57BL/6 mice was established.Mice were randomly assigned into four groups:(1) The recipients in engineering Treg group were injected with 5×10~6 donor bone marrow cells and 5×10~6 splenoeytes plus 5×10~6 genetic engineering Treg;(2)The recipients in transplantation control group were iniected with 5×10~6 donor bone marrow cells and 5×10~6 splenocytes;(3) The recipients in radiation group were injected with 0.2 ml RPMI 1640;(4)The recipients in empty vector control group were injected with 5×10~6 donor bone marrow cells and 5×10~6 splenocytas plus 5×10~6 empty vector transduced CD4~+ CD25~- T cells.Survival time,clinical GVHD Score or histopathological analysis(skin,liver and small intestine) were observed after allo-BMT.Chimerism of bone marrow cells from recipients survived for 60 days after transplantation was measured Results The mean survival times in radiation group, transplantation control group,erIgineering Treg group and empty vector control group were (8.8±0.6),(36.7±2.5),(51.6±4.0) and (34.1±2.3)days respectively.The survival time in engineering Treg group was signiticantly prolonged as compared with other groups as judged by the log-rank test(P<0.05).Histopathological ahalysis in several target organs (skin,liver and small intestine)confirmed the presence of severe GVHD in transplantation control group and empty vector control group. No histological signs of GVHD were observed in recipients in engineering Treg group and clinical GVHD scores in this group were significantly decreased compared to transplantation control group and empty vector control group. Conclusion Co-injection of genetic engineering Treg can efficiently prevent recipients from lethal GVHD during allo-BMT in mice
