The modification of histone is an important mechanism of epigenetics,furthermore histone acetylation and deacetylation is one of the key modifications of histone.There are enhanced expression of histone acetylation and reduced expression and activity of histone deacetylases in asthma,which lead to the unbalance.Glucocoticoids modulate the inflammation of airway in asthma through restoring the balance of the two kinds of enzymes.Theophylline can restore the activity of histone deacetylation in steroid-resistant athma,thereby restoring corticosteroid function.It maybe a new way to find selective histone acetyltransferase inhibitors to therapy asthma.

Objective To evaluate the efficacy,indications and clinical outcomes of the treatment of thoracolumbar fractures by short segmental pedicle screws fixation at the level of the fracture.Methods Thirtytwo patients with thoracolumbar fracture,who underwent surgical procedure of short segmental pedicle screws fixation at the level of the fracture from 2007 to 2010,were followed up.X rays were performed preoperatively and postoperatively to locate the injured vertebral segment height and fractured kyphosis vertebral (Cobb angle).Frankel standard was used to assess the spinal cord function.Results All patients were followed up for 12 to 20 months and were in satisfying condition in the reduction of fracture.After surgery,the height of fractured vertebral body leading edge recovered from preoperative (32.4％ ～69.3％,averaged (51.6 ± 17.8)％ ) to (85.6％ ～99.2％,averaged (92.8 ±6.2)％ ) after two weeks and (90.6％ ～97.8％,averaged (93.8 ±3.6)％ ) at the last follow-up.Fractured vertebral Cobb angle was recovered from the preoperative ( 12.8 ° ～ 30.5 °,averaged [20.8±9.1] °) to (0° ～7.8 °,averaged [4.9 ±3.2] °) two weeks later and (2.0° ～ 12.0°,averaged [ 6.2 ± 4.6 ] o at the last follow-up.Cobb angle of the injured vertebral segment and the extend of vertebral compression were significantly improved after the angle was corrected ( P ＜0.01 ).Conclusion Using reduction and short segment pedicle screw fixation at the fracture level would be helpful to correct kyphotic vertebral compression and restore the height of injured vertebrate,which was also of benefit to increase the stability of short-segment posterior fixation system and reduce the loss of correction in a long run.

Objective To investigate the effects of Tirofiban on the expression of matrix metalloproteinase(MMP-9)and sCD40L in patients with acute coronary syndrome(ACS)after percutaneous coronary intervention(PCI)and to explore the potential mechanism of anti-artherosclerosis and stabilize plaque by Tirofiban.Methods Eighty-six patients with ACS were enrolled and were randomly divided into the control group and the Tirofiban group with different time periods after PCI.The expression of MMP-9 and sCD40L were tested by ELISA at 6 h,12 h,24 h,36 h after PCI.Results After application of Tirofiban 6 h,12 h,24 h,36 h,the expression of MMP-9 decreased from(228.25 ±0.015)ug/L to(53.56 ±0.02)μg/L and the expression of sCD40L decreased from(321.12 ±0.02)ng/L to(123.32 ±0.02)ng/L,compared with the control group,the difference was significant(P ＜ 0.05).Conclusions Tirofiban can inhibite the expression of sCD40L and MMP-9,the inhibition of the expression of MMP-9 may be related to the CD40/CD40L pathway.This effect may be one of the mechanism of reducing atherosclerotic plaque inflammation and preventing plaque rupture by Tirofiban.

AIM: To explore the relationship between methylation status of promoter region 5′CpG island and the biological phenotype in human colorectal cancer RKO cell lines. METHODS: RKO cells were treated with selective DNA methyltransferase (DNMTs) inhibitor, 5-Aza-2′-deoxycytidine (5-Aza-CdR), for 72 h. Methylation-specific PCR (MSP), T-A clone and DNA sequence analysis were used to detect 5′CpG island methylation status of p16/CDKN2 tumor suppresor gene. Cell growth, cell cycle arrest and apoptosis were analyzed by MTT, flow cytometry (FCM), fluorescent dye staining and transmission electron microscope. RESULTS: DNMTs inhibitor (5-Aza-CdR) effectively reversed the hypermethylation status of 5′CpG island. The effects of 5-Aza-CdR on cell growth inhibition (P

OBJECTIVEBy using orthogonal design method to optimnize prescription of pulsed electric field at Jiaji (EX- B 2) points for spinal cord injury (SCI).

METHODSFifty six patients of SCI were selected, in which 36 cases were divided into orthogonal design trial and 20 cases were into clinical verification. With 36 patients who received orthogonal design trial, Frankel grading scale was used as observation index to screen optimal prescription of pulsed electric field. Pulse frequency (factor A) included low frequency (factor A(I), 10(2) Hz). moderate frequency (factor A(II), 10(4) Hz) and high frequency (factor A(III), 10(3) Hz); pulse amplitude (factor B) included 0-30 V (factor B ), 0-60 V (factor B(II)) and 0-90 V (factor B(III)); pulse width (factor C) included 0.1 ms (factor C(I)). 0.6 ms (factor C(II)) and 0.9 ms (factor C(III)); acupuncture time (factor D) included one month (DI), three months (D(II)) and five months (D(III)). Twenty patients were used for clinical efficacy observation and the effects of screened optimal pre scription of pulsed electric field at Jiaji (EX-B 2) points combined with regular rehabilitation training on spasm se- verity, score of sensory and motor functions, Barthel index and Frankel score were observed.

RESULTS(1) As results of orthogonal design trial, the optimal prescription was A(III) B(III), C(I), D(III), which were high frequency (10(3) Hz), 0-90 V of pulse amplitude, 0.4 ms of pulse width and 5 months of treatment time. (2) As results of 20 patient clinical verification, Ashworth score, tendon reflex and clonus were all significantly improved (P<0.001, P<0.01), the scores of sensory and motor functions were evidently improvedtl (P<0.001, P<0.05), and Barthel in dex and Frankel score were also enhanced (P<0.001, P<0.05).

CONCLUSIONThe optimal prescription of pulsed electric field at Jiaji (EX-B 2) points for spinal cord injury is high frequency (10& Hz), 0-90 V of pulse amplitude, 0.4 ms of pulse width and 5 months of treatment time. The optimal prescription of pulsed electric field at Jiaji (EX-B 2) points combined with regular rehabilitation could obviously improve spasm severity, enhance senso- ry and motor functions, and ameliorate activity of daily life and Frankel score.
