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.

Using universal primer Tyl-copia retrotransposon RT, the conserved reverse transcriptase domain of about 260 bp was amplified by RT-PCR from the Dendrobium officinale which induced by 100 micromol x L(-1) abscisic acid (ABA), indicating these retrotransposons activated by 100 micromol x L(-1) ABA. The amplicons were recovered and cloned,then sequenced and analyzed by related bioinformatics software. Forty-two Ty1-copia like retrotransposon RT transcriptionally activated were obtained with high heterogeneity. The length of these sequences varied from 247 to 266 bp, and was rich in AT and homology ranged from 46.3% to 98.9%. The same to Ty1-copia like retrotransposon RT of genome, different c/s-acting regulatory elements induced by stress conditions and the starting transcription signals, corresponding to CAAT box, TATA box conserved sequences and some other regulatory elements. The c/s-acting regulatory elements induced by stress conditions of reverse transcriptase transcriptionally activated of Tyl-copia retrotransposons were significantly increased than that of Ty1-copia like retrotransposon RT of genome. When being translated into amino acids, fifteen sequences presented stop codon mutation, nineteen sequences presented frameshift mutation, and all sequences presented conserved sequence "SLYGKQ" mutation. Five categories were identified through phylogenic analysis after alignment analyses of their amino acid sequences, and with Ty1-copia like retrotransposon RT of genome having low homology, which indicated that reverse transcriptase transcriptionally activated of Ty1-copia retrotransposons which induced by ABA had Significantly differences with Ty1-copia like retrotransposon RT of genome.

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.

OBJECTIVE:
To construct a W203X-mutant mouse model of cblC type methylmalonic acidemia based on the CRISPR/Cas9 technology.
METHODS:
At first, BLAST was used to compare the conservative nature of the cblC gene and protein sequences in humans and mice, and then, the CRISPR/Cas9 technology was used for microinjection of mouse fertilized eggs to obtain heterozygous F1 mice. Hybridization was performed for these mice to obtain homozygous W203X-mutant mice. The blood level of the metabolite propionyl carnitine (C3) was measured for homozygous mutant mice, heterozygous littermates, and wild-type mice.
RESULTS:
The gene and protein sequences of MMACHC, the pathogenic gene for cblC type methylmalonic acidemia, were highly conserved in humans and mice. The homozygous W203X-mutant mice were successfully obtained by the CRISPR/Cas9 technology, and there was a significant increase in C3 in these mice at 24 hours after birth (P<0.001).
CONCLUSIONS
A W203X-mutant mouse model of cblC type methylmalonic acidemia is successfully constructed by the CRISPR/Cas9 technology.

OBJECTIVETo observe the changes of sex hormones and sexual function in male patients with Graves' disease (GD) after Radioiodine-131 (I-131) therapy.
METHODSThirty-four male GD patients, aged 21 -40 (32.3 +/- 6.7) years, were treated with I-131 at the dose of 111 - 407 (237.8 +/- 51.8) MBq. The levels of serum sex hormones were measured, and the patients'scores on erectile function (IIEF-5) were obtained before and 3 and 6 months after the treatment. Another 20 healthy men aged 25 - 37 (31 +/- 3.1) years were enlisted as controls.
RESULTSThe baseline levels of estrogen (E2), testosterone (T) and luteinizing hormone (LH) were (132.5 +/- 40.4) pmol/L, (21.6 +/- 4.6) nmol/L and (10.1 +/- 4.4) IU/L in the GD patients, significantly higher than (80.4 +/- 31.2) pmol/L, (14.5 +/- 4.2) nmol/L and (6.2 +/- 1.9) IU/L in the healthy controls (P < 0.05). The E2, T and LH levels showed a significant decrease in the GD patients after 3 months of treatment ([110.2 +/- 20.6] pmol/L, [17.7 +/- 5.5] nmol/L and (9.4 +/- 3.9) IU/L, P < 0.05), but exhibited no statistically significant differences from the healthy controls at 6 months ([82.6 +/- 30.1] pmol/L, [13.8 +/- 3.4 ] nmol/L and [6.6 +/- 1.5] IU/L, P > 0.05). The IIEF-5 score of the GD patients was 5 - 25 (15.5 +/- 3.5) before I-131 treatment, significantly lower than that of the controls (19 - 25, 24 +/- 0.5) (P < 0.05), and it was 8 - 25 (19.5 +/- 1.0) at 3 months and 10 - 25 (23.5 +/- 1.5) at 6 months, significantly higher in the latter than in the former (P < 0.05), and with no significant difference between the 6-month treated patients and the healthy controls (P > 0.05).
CONCLUSIONThe E2, T and LH levels are increased while the IIEF-5 score decreased markedly in male GD patients. Six-month treatment with I-131 can not only restore the E2, T and LH levels to normal but also significantly improve the patient's sexual function.

The purposes of this study were to investigate the effect of emodin on expression of BKCa channel β1 subunit in basilar artery smooth muscle cells (BASMCs) and electrophysiological characteristics of vascular smooth muscle cells in spontaneously hypertensive rats (SHR). Tail artery pressure measurement instrument was used to measure the change of SHR systolic blood pressure before and after emodin intervention. Single vascular smooth muscle cell was electrically recorded by whole-cell patch-clamp technique. Immunohistochemistry and Western blotting were used to study the distribution and expression of the BKCa channel β1 subunit. The results showed that emodin decreased blood pressure of SHR from (223 ± 16) mmHg to (127 ± 12) mmHg (P < 0.01). There was no difference of blood pressure between emodin-treated SHR and Wistar rats. Emodin significantly increased outward currents of smooth muscle cells in SHR (P < 0.05), and this effect could be reversed by specific inhibitor of BKCa channel, IbTX. Emodin also up-regulated BKCa channel β1 subunit expression in BASMCs. These results suggest that emodin relaxes cerebral basilar artery by enhancing BKCa current via increasing β1 subunit expression in BASMCs.
