Objective To explore the mechanism of long chain noncoding RNA RORin regulating prolifer-ation and apoptosis of pancreatic cancer cell. Methods Pancreatic cancer cell line BxPC-3 was selected. The RNA level of lncRNA ROR and notch1 was detected by RT-PCR.Notch1 protein level was detected by Western blot. The regulating relationship between lncRNA ROR and notch1 was analyzedby RNAhybird and luciferase re-porter assay. At last ,CCK-8 and TUNEL were applied to detectthe proliferation and apoptosis of cell line. Re-sults lncRNA ROR and notch1 were highly expressed in pancreatic cancer tissue ,compared with normal tis-sues. There was positive correlation between them. lncRNA ROR was over-expressed in BxPC-3,cell proliferation activity was increased and the percentagesof DNA damaged positive cells was decreased ,accompanied by in-creased levels of notch1 mRNA and protein. Luciferase assay confirmed that ROR could bind to notch1and inhibit its activity by miR-137. Compared with control group ,the proliferation of pcDNA-ROR + si-notch1 cells reduced and the proportion of TUNEL positive cells increased. The differences were statistically significant. Conclusionl ncRNA ROR regulated the proliferation and apoptosis of pancreatic cancer cells by promoting the expression of notch1.

HSP90, which is the biomarker of cell stress and endogenous protective protein, functions as a molecular chaperone. Many client proteins of HSP90, including EGFR, Met, Raf-1, IKK and p53, play important roles in the occurrence and development of tumor. Binding of HSP90 inhibitors triggers the deactivation of HSP90, resulting in client protein degradation, and hence inhibits the tumor growth by blocking multiple targets involved in signaling of tumor proliferation. This review summarizes recent development of small molecule inhibitors bound to N-terminal of HSP90.

Objective To analyze the motion, elastic and derived parameters of normal common carotid artery (CCA) wall in short-axis orientation with velocity vector imaging (VVI) technique. Methods Two-dimensional dynamic images of CCA in 40 healthy volunteers people were obtained in short-axis view with Siemens Acuson Sequoia 512 color Doppler ultrasound. The motion, elastic and derived parameters were analyzed in right CCA including 6 segments: Anterior wall, posterior wall, anterolateral wall, anterior internal wall, posterolateral wall and posterointernal wall. Relationship between these parameters and the influencing factors were analyzed as well. Results There was no statistical difference of the elastic parameters among 6 walls (P>0.05). Some of the motion parameters of the lateral wall and anterior wall were higher than those of the posterior wall and internal wall (P<0.05). Age and intima-media thickness were negatively correlated with some elastic parameters and some motion parameters (P<0.05). Heart rate were positively correlated with some elastic parameters and some motion parameters (P<0.05). Elastic parameters were positively correlated with motion parameters (P<0.05) and positive correlation was found between time to peak of elastic and motion parameters (P<0.05). Conclusion VVI is an effective technique for observing CCA mechanical characteristics of the movement in normal human, and has potential for studying some of related factors of the characteristics.

BACKGROUND:With the development of microsurgical techniques, free flap transplantation has been widely used, which can solve the problem of insufficient local tissues.
OBJECTIVE:To observe the clinical effects of latissimus dorsi free flap transfer on the repair of al kinds of body surface defects, as wel as the role in complete tissue and functional reconstruction.
METHODS:From 2010 to 2013, 18 cases of various types of body surface defects were selected and using the microsurgical techniques, these complex wounds were repaired with free latissimus dorsi myocutaneous flaps. According to defect reason, primary wounds were treated for arteriovenous separation in the recipient zone. Most of the flaps were latissimus dorsi myocutaneous flaps at the affected side which were cut according to the wound size. If the cut muscle flap had a larger size and secondary wounds were difficult to be directly sutured, free skin grafts could be used to cover the residual secondary wounds.
RESULTS AND CONCLUSION:After transplantation, al the flaps survived with normal blood supply and wel-recovered function. Patients were more satisfied with the flap appearance. Latissimus dorsi myocutaneous flaps characterized as large donor area and secluded location have a great advantage in the repair of complex wounds using microsurgical techniques that can improve the survival rate of latissimus dorsi myocutaneous flaps.

BACKGROUND: It has reported that nicotinamide is capable of protecting intervertebral disc (IVD) against interleukin-1β (IL-1β) or tumor necrosis factor-alpha (TNF-α) induced degeneration. However, the protective mechanism of nicotinamide on IVD cells apoptosis and proliferation remains unclear.OBJECTIVE: To investigate regulatory effects of nicotinamide on rabbit nucleus pulposus cell apoptosis and proliferation in vitro.DESIGN, TIME AND SETTING: Randomized control grouping design, which was carried out in the Laboratory of Orthopaedics and Stem Cell Center, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology from April to October 2007.MATERIALS: Ten Japanese white rabbits (aged 2-3 months weighing 1.5-2.0 kg) were used in this study. Furthermore, nucleus pulposus cells obtained from L1-6 lumbar spine were harvested and cultured for further experiments.METHODS: The NP cells were divided into 6 groups, including control group (without any drug as control), nicotinamide group (0.5 g/L nicotinamide), IL-1β group (10 μg/L IL-1β), IL-1β + caspase group (10 μg/L IL-1β and non-specific caspase inhibitor Z-VAD-FMK), IL-1β + small-dose nicotinamide group (10 μg/L IL-1β and 0.05 g/L nicotinamide), and IL-1β + large-dose nicotinamide group (10 μg/L IL-1β and 0.5 g/L nicotinamide). After 3 days of culture, the cells were examined with Annexin V-PI staining, caspase-3, 8 and 9 activity staining and MTT assay.MAIN OUTCOME MEASURES: The apoptotic rates, the positive rates of caspase-3, 8 and 9 activity staining and the absorbance of MTT assay of each group.RESULTS: ① As compared to IL-1β group, the apoptotic rates were decreased in the IL-1β + caspase group and IL-1β + large-dose nicotinamide group (P < 0.01). ②As compared to IL-1β group, the positive rates of caspase-3, 8 and 9 activity staining were decreased in the IL-1β + caspase group, IL-1β + large-dose and small-dose nicotinamide groups (P < 0.01 or P < 0.01). ③As compared to IL-1β group, the absorbance was increased in the IL-1β + caspase group and IL-1β + large-dose nicotinamide group (P < 0.01).CONCLUSION: Nicotinamide is capable of promoting cell proliferation and inhibiting IL-1β induced apoptosis of nucleus pulposus cells in vitro. The inhibition of apoptosis mainly acts via inhibition of the mitochondrial pathway.
