Purpose To explore the expression of Aurora kinase A (Aurora-A), minichromosome maintenance protein 7 (MCM7) and human papillomavirus type 16 E7 protein (HPV 16 E7) in uterine cervical squamous cell carcinoma (CSCC) and to investigate their relationship with clinicopathological factors. Methods Immunohistochemical method was employed on 20 cases of low-grade cervical intraepithelial neoplasia (CIN1) , 30 cases of high-grade cervical intraepithelial neoplasia (CIN2+3), 40 cases of CSCC, and 20 ca-ses of chronic cervicitis. Results (1) Aurora-A localized in the cytoplasm and nucleus. MCM7 protein positive staining localized in the nucleus. In the nucleus, and (or) the cytoplasm appeared brown particles positive for HPV 16 E7. (2) The expression of Aurora-A, MCM7 and HPV 16 E7 were higher in the group of CIN2+3 and CSCC than that in the group of chronic cervicitis or CIN1 ( P<0. 0083). (3) In cervical cancer, the expression of Aurora-A, HPV 16 E7 showed positive correlation (P<0. 001, rs =0. 657). The expression of MCM7, HPV 16 E7 showed positive correlation (P<0. 001, rs =0. 616). The expression of Aurora-A, MCM7 showed positive correlation (P<0. 001, rs =0. 597). (4) Aurora-A expression levels was associated with tumor cell differentiation, clinical stage and lymph node metastasis (P<0. 05). MCM7 expression levels was associated with tumor cell differentiation and clinical stage (P<0. 05). HPV 16 E7 expression had no correlation with patient age, tumor size, tumor differentiation, clinical stage and lymph node metastasis (P>0. 05). Conclusion Aurora-A, MCM7 and HPV 16 E7 expression are gradually increased with disease progres-sion, and closely related to the occurrence and development of cervical cancer, they are expected to be early diagnosis, early treatment of biological indicators of cervical cancer.

Objective To evaluate the efficacy and safety of recombinant adenovirus-p53 (rhAd-p53) combined with neoadjuvant chemotherapy in treatment of locally advanced cervical cancer.Methods Forty patients with stage Ⅰ R2-Ⅲ A locally advanced cervical cancer were randomly divided into 2 groups,gene therapy + neoadjuvant chemotherapy group (rhAd-p53+PVB group,n =20.They received one course of chemotherapy consisting of PVB.rhAd-p53 solution 1 ×1012 VP was injected intratumorally every three days for three circles since the 3rd day of PVB chemotherapy) and chemotherapy group (PVB group,n=20,the above course of chemotherapy was conducted).The volums of tumors was observed.Patients were monitored for adverse event.The expression of VEGF,p53 pertein and MVD in tumor tissue was detected by immunohistochemistry.Results The evaluation was performed three weeks after the completion of chemotherapy.The PVB group response rate (CR+PR) was 75 ％,while the effective rate was 95 ％ of the PVB combined with gene group.After using of the PVB chemotherapy,the tumor was shrunk by (11.42±2.78) cm2.However,the volums of tumor were significantly shrunk by (15.25±4.00) cm2 using the PVB combined with gene therapy,and P ＜ 0.05.The positive expression rate of VEGF,p53 protein and MVD were reduced respectively in PVB group and rhAd-p53 + PVB group with statistic significance.There were no additional adverse events by recombinant adenovirus-p53 combined with neoadjuvant chemotherapy.Conclusion A potentially gene therapeutic agent for cervical cancer treatment,intratumoral injection of rhAd-p53 is effective.

Objective To explore the effects of the extracellular regulated protein kinase’s (ERK1/2) inhibitor PD98059 and ino-sitol triphosphate kinase (PI3K/PKB) signaling pathway’s inhibitor LY294002 on extracellular matrix (ECM) deposition in pulmonary arterial smooth muscle cells (PASMCs) stimulated by connective tissue growth factor (CTGF). Methods PASMCs of SD rat were cul-tured in vitro. The PASMCs were divided into control group, CTGF group, CP (CTGF+PD98059) group, CL (CTGF+LY294002) group and CPL (CTGF+PD98059+LY294002) group. Real-time lfuorescent quantitative RT-PCR was used to detect the expression of colla-gen III and ifbronectin mRNA of PASMCs, and the expression of collagenШprotein of PASMCs was detected by immunohistochem-istry and western-blot. Results The expressions of collagenШand ifbronectin mRNA of PASMCs stimulated with CTGF (50 ng/ml) for 48 h were signiifcantly higher than those in control group, and the collagen proteinШof PASMCs was decreased signiifcantly after stimulation with CTGF (50 ng/ml) for 72 h (P<0.05). The expressions of collagenШand ifbronectin mRNA in PASMCs cultured with PD98059 (20μmol/L) and/or LY294002 (10μmol/L) for 48 h was signiifcantly lower than those in CTGF group (P<0.05). The collagen proteinШin PASMCs cultured with PD98059 (20μmol/L) and/or LY294002 (10μmol/L) for 72 h was increased (P<0.05). The expres-sions of collagenШand ifbronectin mRNA of PASMCs stimulated with both PD98059 and LY294002 were more signiifcant. Conclu-sions CTGF may increase the expression of collagenШand ifbronectin mRNA in PASMCs, which may contribute to the deposition of ECM in PASMCs during pulmonary vascular remodeling. PD98059 and LY294002 may repress ERK1/2 and PI3K/PKB signaling pathways and interfere with the biological effect of CTGF.

Objective To explore the mechanisms of integrin β1 on connective tissue growth factor(CTGF)-induced proliferation,migration,change of cytoskeleton of pulmonary arterial smooth muscle cell(PASMC) in vitro,and to investigate the effects of CTGF-integrin β1 signal pathway on pulmonary vascular remodeling in pulmonary arterial hypertension (PAH).Methods Pulmonary artery smooth muscle cells of SD rats were cultured in vitro.WST-1 assay was used to detect the effects of anti-integrin β1 antibody on CTGF-induced proliferation of PASMC.Transwell chambers were used to observe the effects of anti-integrin β1 antibody on CTGF-induced migration of PASMC.The cytoskeletal rearrangement was observed with coomassie brilliant blue R250 staining and Confocal Lasar Scanning Microscopy (CLSM).Results Different concentration of anti-integrin β1 antibody could inhibit the proliferation of PASMC induced by CTGF,which presents concentration dependent pattern (P ＜ 0.05).The higher the concentration of anti-integrin β1 antibody,the more severity the proliferation of PASMC induced by CTGF was inhibited.and inhibition rate of PASMC proliferation was the highest at 72 hours.Anti-integrin β1 antibody(15 mg/L) decreased significantly the number of PASMC passing through Transwell induced by CTGF,compared with CTGF group (P ＜ 0.01).Meanwhile,antiintegrin β1 antibody could change cytoskeletal rearrangement of PASMC induced by CTGF.Conclusions Integrin β1mediates the proliferation,migration,cytoskeletal rearrangement of PASMC induced by CTGF.The CTGF-integrin β1signal pathway may play a key role in proliferation,migration,cytoskeletal rearrangement PASMC.

Objective To observe the clinical efficacy of cerebral palsy children with liver strong spleen weak syndrome treated with integrated traditional Chinese medicine therapy. Methods Eighty cerebral palsy children with liver strong spleen weak syndrome were divided into treatment group (40 cases) and control group (40 cases). Patients in control group were treated with conventional therapy (including exercise therapy, occupational therapy, guidance education, physical factors, and psychological therapy), and patients in treatment group were treated with integrated traditional Chinese medicine therapy (acupuncture and traditional Chinese medicine medicated bath) additionally. Three months were set for a course of treatment, and the whole treatment lasted for a total of four courses. TCM clinical symptoms were scored every six months, muscle tone (MAS), gross motor function (GMFM), and daily life activity ability (MBI) were evaluated every three months for both groups. Results There were significant differences in the total scores of TCM clinical symptom, MAS, GMFM, and MBI at different treatment time points in the two groups, compared with that before treatment (P<0.01). There were significant differences in the total scores of clinical symptom for Chinese medicine, MAS, GMFM, and MBI at different treatment time points for treatment group, compared with that of control group (P<0.05). Conclusion Integrated traditional Chinese medicine therapy (acupuncture and traditional Chinese medicine medicated bath) for cerebral palsy children on the basis of western medicine therapy can more effectively improve function and life quality of children patients.

BACKGROUND:Cytoskeleton plays an important role in the transduction of mechanical signal, and intermittent tensile stress can promote osteogenic differentiation. However, there is no relevant study about the change of cytoskeleton in osteoporosis rat bone marrow mesenchymal stem cells under intermittent tensile stress. OBJECTIVE:To investigate the effects of intermittent tensile stress on the cytoskeleton of osteoporosis rat bone marrow mesenchymal stem cells during osteogenic differentiation. METHODS:Bone marrow mesenchymal stem cells were obtained from osteoporosis rats and cultured in vitro. The 5%, 10%and 15%tensile stress were strained on the bone marrow mesenchymal stem cells through FX-4000T Flexcell. No stress was in the control group. Osteogenic differentiation of bone marrow mesenchymal stem cells was observed through alkaline phosphatase staining, while the change of cytoskeleton was observed by confocal laser scanning microscopy with figures col ected for analysis by Image-ProPlus 6.0 software. The area of cells, ratio of length to width and integrated fluorescence intensity of cytoskeleton protein F-actin were measured. RESULTS AND CONCLUSION:Under tensile stress, bone marrow mesenchymal stem cells from osteoporosis rats arranged in the direction vertical to mechanical stimulation. cells under different tensile stress differentiated towards osteoblasts. The result of alkaline phosphatase staining showed the most significant difference in 10%group, and quite an amount of cells lining lost succession in the 15%group. Under stress, the F-actin filaments were rearranged in paral el accordingly, which showed a reconstruction of cytoskeleton. Imaging analysis indicated that the area of bone marrow mesenchymal stem cells was decreased in 10%and 15%groups (P<0.05) with the increased ratio of length to width (P<0.05), and expression of F-actin increased in5%, 10%, 15%groups (P<0.05) after tensile stress. Under mechanical stimulation, the cytoskeleton of bone marrow mesenchymal stem cells from osteoporosis rats is shown to have corresponding alterations during osteogenic differentiation.
