According to the base complementation, the principle antisense technology is the sequence specific binding of complementary antisense nucleic acids or their chemical modification to the nucleic acids in cells, resulting in the suppression or prevention of gene translation. For the treatment of cancer, a lot of antisense drugs have been designed, which target the genes involved in the pathogenesis of cancer. And some of them have been in clinical trials. The author reviewed the progress of the clinical trials of these antisense drugs.

OBJECTIVETo explore the curative effect and safety of acupuncture for mild cognitive disorders after stroke.

METHODSRandomized controlled trial was adopted and one hundred cases conforming to criteria were divided into a combined acupuncture and medication group (group A) and a medication group (group B), 50 cases in each group. The basic treatment of cerebrovascular disease was applied in two groups. The group A treated was with acupuncture at Baihui (GV 20), Shenting (GV 24) and Qucha (BL 4) etc. and oral administration of Nimodipine. In group B, Nimodipine was taken orally. The treatment lasted for 3 months, the scores of Mini-Mental State Examination (MMSE), modified Hasegawa Dementia Scale (HDS-R) and Barthel Index (BI) were observed before and after treatment in two groups.

RESULTSThe total effective rate in group A was 66.7% (32/48), which was superior to 30.4% (14/46) in group B (P < 0.05). The scores of MMSE, HDS-R and BI after treatment were apparently improved as compared with those before treatment in two groups (all P < 0.01). The improvements in group A were superior to those in group B (all P < 0.05). There was no adverse event reported during the treatment in two groups.

CONCLUSIONAcupuncture can improve activity of daily living and has significant effect in treating mild cognition disorders after stroke without adverse reactions.

This study is to investigate the protective effect of mangiferin on NF-kappaB (P65) and IkappaBalpha expression in peripheral blood mononuclear cell (PBMC) in rats with cigarette smoke induced chronic bronchitis. The rat model with chronic bronchitis was established by cigarette smoke. Real-time fluorescence RT-PCR was executed for evaluating the NF-kappaB (P65) and IKkappaBalpha gene expression in mononuclear cell, and flow cytometry for their protein expression. The serum hs-CRP (high-sensitivity C-reactive proteins) and TNF-alpha (tumor necrosis factor-alpha) were detected by enzyme-linked immunosorbent assay. The histopathological score was obtained from lung tissue HE staining slides of lung tissue. The results showed that mangiferin could markedly suppress the NF-kappaB (P65) mRNA and protein expression in mononuclear cell, while promote the IkappaBalpha mRNA and protein expression. Furthermore, mangiferin could lower serum hs-CRP and TNF-alpha level, and reduce the chronic inflammatory damage of bronchiole. These results suggested that mangiferin could notably ameliorate chronic bronchiole inflammation induced by cigarette smoke, and this protective effect might be linked to the regulation of NF-kappaB (P65) and IkappaBalpha expression in mononuclear cell.

Objective To study the elongation factor 1α(EF-1α) gene functions in prostate cancer cell line DU145 in the aspects of cell proliferation and clone formation by using the RNA interference technique. Methods DU145 cell lines were divided into control group, transfection control group transfected with scramble siRNA and experimental group transfected with EF-1α siRNA. After transfecting EF-1α siRNA into DU145 cell line, the down-regulation of EF-la expression in DU145 cell line was confirmed by Western blotting and immunofluorescence staining. Then, the cell proliferation and clone formation assays were carried on in these 3 groups of DU145 cells. Results Compared with controls, the specific down-regulation of EF-1α expression was achieved in experimental group only. Compared with control group, after the down-regualtion of EF-1α in DU145 cell line, the cell proliferation rate decreased from day 4 to day 7 after transfection by 45. 9%, 53. 5% , 35. 3% and 38. 1% , respectively(P<0. 05). The clone formation number in experimental group decreased by 67.0% (P<0. 01). Conclusions The down-regulation of EF-1α has a negative impact on prostate cancer cell proliferation and clone formation. EF-1α might be an appropiate targeting gene in prostate cancer targeting therapy.

Objective To study the effect of down-rdgulation of EF-1 alpha gene in prostate cancer cell line DU-145 on cancer cell migration and invasion by using RNA interference technique. Methods The prostate cancer cell line DU-145 was divided into three groups: the control group (untransfected with siRNA), randomly control group (randomly transfected with siRNA) and experimental group (transfected with EF-1 alpha siRNA). Localization of EF-1 alpha and its relationship with F-actin in cytoplasm were analyzed by immunofluorescence technique. Cancer cell migration and invasion capability of DU145 cells were studied by transwell technique in these three groups. Results EF-1 alpha expression in DU145 cell line was down-regulated by using RNA interference technique. EF-1 alpha was localized in cytoplasm and co-located with F-actin. The down-regualtion of EF-1 alpha did not change the F-actin distribution in cytoplasm. The cell migration and invasion study showed that after seeding 20×104 DU145 cells into the upper chamber of transwall for 12 hours, the cells collected in the lower chambers were (10.6±1.0)×104 in control group, (11.2±0.8)×104 in randomly control group and (3.9±0.6)×104 in experimental group. Compared with controls, the cancer cell migration and invasion capability was significantly inhibited to only 37.1% (t= 13.9, P<0.05) after the specific down-regulation of EF-1 alpha expression in DU145 cells. Conclusions The down-regulation of EF-1 alpha expression has negative impacts on prostate cancer cell migration and invasion. EF-1 alpha plays important roles in prostate cancer local invasion.

Objective To approach the effective treatment for simple bone cyst in adult. Methods Forty-eight cases were divided into two groups by visiting order, 20 cases (steroid group) were treated by prednisolone acetate and 28 cases (open resection and allograft group) were treated by open resection and allograft. The curative effect were contrasted between two groups. Results The follow-up time was 5-46(26.58 ± 10.81) months. Aecording to the Chigira's healing criteria for simple bone cyst, grade Ⅰ , Ⅱ , Ⅲ,V were 1, 2, 10 and 7 cases respectively in steroid group, contrasting to 0, 3, 5 and 20 cases respectively in open resection and allograft group. The recovery rate was 85.0%(17/20) in steroid group and 89.3%(25/28) in open resection and allograft group, which was no statistically significant difference between two groups (P＞0.05). Conclusions Although the two remedies are no obvious difference in curative effect,simple bone cyst at lower extremity of weight-bearing with obvious osteolysis in adult is recommended to open resection and allograft, otherwise or at upper extremity to steroid injection.

OBJECTIVETo discuss the relative association of soft tissue tension and cervical physiological curvature chang in patients with scapula muscle fasciitis.

METHODSFrom February 2012 to December 2012,29 patients with scapula muscle fasciitis were investigated. There were 10 males and 19 females with an average age of 27.77 years old (ranged from 22 to 40 years old). Routine AP and lateral cervical X-rays were done in all patients. Cervical lordosis was measured according to Borden's method and the pain point tension was measured by soft tissue tension meter. Finally,perform statistic analysis to bove data.

RESULTSLateral X-rays showed 9 cases were normal cervical lordosis, 18 cases were cervical lordosis decreased, 2 cases were cervical lordosis increased. The regression equation of cerical lordosis changes D(Y) and soft tissue tension displacement D0.5 kg (X) was Y = -15.069 + 3.673X.

CONCLUSIONThere is linear relationship between soft tissue tension and cervical physiological curvature change. With the soft tissue tension increases, the cervical lordosis trend to decrease.

Background and purpose:Correct target positioning is an important factor affecting the precision of stereotactic body radiotherapy (SBRT) in patients with lung tumors. This study investigated the setup errors in patients with malignant lung tumors receiving SBRT with cone-beam CT (CBCT) and analyzed the factors influencing setup errors.Methods:Twenty-nine patients with solitary malignant lung tumors were enrolled in the study. Each patient underwent SBRT with CBCT before each treatment. Setup errors in CBCT were obtained according to the matched and planned CT images in anterior-posterior (AP), superior-inferior (SI) and left-right (LR) directions. The expanding margins of clinical target volume (CTV) to planning target volume (PTV) according to the analyzed setup errors were then calculated. And the influencing factors of setup errors were analyzed.Results:A total of 155 CBCT images from 29 patients were obtained during the treatment. The setup errors were (-1.68±3.62), (-1.34±3.90) and (0.36±2.15) mm in the AP, SI and LR directions, respectively. The absolute setup errors were (3.16±2.42), (3.29±2.48) and (1.74±1.30) mm in the AP, SI and LR directions, respectively. The suggested expanding margins of CTV to PTV were 9.6, 10.0 and 5.3 mm in the AP, SI and LR directions according to the setup errors. The setup errors in the AP direction of peripheral lesions and in the SI direction of inferior, right and metastatic lesions were relatively larger(P=0.007, 0.008, 0.000 and 0.000)..Conclusion:In patients with malignant lung tumors receiving SBRT, the setup errors were more obvious in the SI and AP directions. Tumor motion management techniques including CBCT, breath-holding technique are required to reduce the setup error in patients with lung tumors receiving SBRT.

OBJECTIVE:To systematic review the relationship between CYP4F2 gene polymorphism and warfarin maintenance dose in Chinese population,and to provide evidence-based reference for clinical treatment. METHODS:Retrieved from Cochrane library,PubMed,EMBase,CJFD,VIP and Wanfang database,studies about the relationship between CYP4F2 gene polymorphism and warfarin maintenance dose in Chinese population were collected,and Meta-analysis was performed by using Rev Man 5.0 statis-tics software. RESULTS:A total of 13 studies were included,involving 2 958 patients. The type of gene was type TT,type CT and type CC. Results of Meta-analysis showed the relationship between 3 gene polymorphism and warfarin maintenance dose was type TT>type CT>type CC,and there were significant differences among groups. CONCLUSIONS:CYP4F2 gene polymorphism in Chinese population has significant correlation with warfarin maintenance dose. However,due to the limit of methodological quali-ty,large-scale and high quality studies are required for further validation of the conclusions.
