Purpose To explore the role of histone H2B monoubiquitination in primary colonic carcinoma and clinicopathological pa-rameters of colonic carcinoma. Methods To detecte the expression of histone H2B monoubiquitination in 116 cases of primary colonic carcinoma and 15 cases of normal colonic mucosal tissue by avidin-biotin-peroxidase complex ( ABC)-immunohistochemistry. Results The level of histone H2B monoubiquitination was significantly reduced in poorly differentiated colonic carcinoma 19. 4% (6/31) compared with that of well-differentiated colonic carcinoma 49. 4%(42/85), moderately differentiated colonic carcinoma 49. 4% (42/85) and normal colonic mucosal tissue 86. 7% (13/15) (P<0. 05). The expression of histone H2B monoubiquitination was closely correlated with tumor differentiation, Dukes stage, TNM stage and lymph node metastasis (P<0. 05), but not depended on sex or age (P>0. 05). Conclusion Histone H2B monoubiquitination is obviously associated with the progression of primary colonic carcinoma. Although its specific mechanism still remains unclear, histone H2B monoubiquitination could be a novel potential molecular marker for early diagnosis, clinic treatment and prognosis evaluation.

Objective: To analyze chromosome aberrations in bladder transitional cell carcinoma with exfoliated cells, and to evaluate the clinical value of fluorescence in situ hybridization (FISH) in bladder cancer. Methods: FISH was performed using centromeric probes of 3, 7, 17 and locus probe of p16 to examine chromosome aberrations of exfoliated cells of 56 bladder cancer patients and 20 healthy controls to analyze the correlation of chromosome aberration with the pathological features of bladder cancer. The urine cytology of the 56 bladder cancer patients was performed. Results: The rates of aneuploidy of chromosomes 3, 7, and 17 were 58.9%, 39.3%, 58.9% and 75.0% for aberration of p16 in exfoliated cells from the 56 bladder cancer patients. All of the aberrations had no correlation with tumor stage (P>0.05). The aberrations of chromosomes 3, 7, and 17 were significantly correlated with pathological grade (P<0.05). The sensitivity of the 4 chromosome probes for detecting bladder cancer was 80.4%. The detection rate of FISH was obviously higher than that of udne cytology. Conclusion: Chromosome aberration is correlated with the growth of bladder cancer. The detection of FISH has significance for early di-agnosis, prognosis evaluation, and recurrence monitoring of bladder cancer.

Objective To investigate the effects of aquatic Taiji Quan on balance function of patients with incomplete spinal cord injury. Methods From March to December, 2015, 30 patients with incomplete spinal cord injury received aquatic Taiji Quan exercise based on rou-tine rehabilitation, 30 minutes every day, five times a week for five weeks. They were assessed with Berg Balance Scale (BBS) before and after exercise. Dynamic balance function and static balance function were also assessed with Active Balancer assessment. Results The BBS score significantly improved after exercise (t=-9.652, P<0.001). The track length and area of gravity movement with eyes open and closed decreased (t>3.528, Z>-2.590, P<0.01). No improvement was observed in the deflection center displacement of X and Y axes (P>0.05). The dynamic stability limit range enlarged (t=-4.516, P<0.01), and the time to target significantly shortened (t=4.530, P<0.001). Conclusion Aquatic Taiji Quan can improve the balance function of patients with incomplete spinal cord injury.

Using universal primer Ty1-copia retrotransposon RT,43 Ty1-copia like retrotransposon RT with high heterogeneity, stop codon mutation and frameshift mutation were amplified by PCR from genomic DNA of Zhejiang Lin'an (C15) and Yunnan Guangnan (A39) of Dendrobium officinale. The length of these sequences varied from 260 to 266 bp, and was rich in AT and consistency ranged from 47.1% to 97.7%. Different c/s-acting regulatory elements induced by low temperature, heat, light, all kinds of plant growth regulating substances and the starting transcription signals, corresponding to CAAT box, TATA box conserved sequences and some other regulatory elements. When being translated into amino acids, ten sequences presented stop codon mutation, five sequences presented frameshift mutation, and thirty-seven sequences presented conserved sequence "SLYGKQ" mutation. Six categories were identified through phylogenic analysis after alignment analyses of their amino acid sequences, and with other plants (eg. Triticum aestivum, Eleocharis quinqueflora) having high homology, which indicated that horizontal transmission of retrotransposon occurred among the plants in the past.

Objective To observe the effects of electrical acupuncture for the treatment of neurogenic detrusor overactivity (DO) caused by spinal cord injury (SCI).Methods Twenty SCI patients with DO were included in this study. There were 18 males and 2 females;age ranged from 17 to 58 years. Patients were given electro-acupuncture treatment at the bilateral S3 foramen at the lateral position during the vidio-urodynamic investigation when the detrusor of the patients began to contract.The different intensities of electrical stimulation were used when the DO appeared during cystometry and the most effective intensity to inhibit DO was determined. Then, the bladder was emptied and the stimulation with selected intensity was used at the beginning of cystometry. The changes of parameters in the urodynamics, the urinary incontinence times per day and the pad used per day were recorded. The acute effects were observed. Ten days were set as one course and after 3 courses and 9 courses the patients underwent urodynamic test again. The long-term effects were observed.Results After treatment, the urinary incontinence times per day and the pad used per day decreased obviously (P<0. 05). The bladder capacity increased significantly and the maximum intravesical pressure decreased significantly. There were 3 patients having the long terms treatment. Conclusions The Chinese electro-acupuncture at S3 foramen in the SCI patients with DO is demonstrated effective. After the treatment bladder capacity could increase and the times of the urinary incontinence per week decrease.
