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.

The 23 patients in the experimental group received one-week wet compress with 5g/100ml flos lonicerae twice to five times per day. While the 19 patients in the control group were given wet compress with tepid water. The efficacy on day 3 and day 7 were observed. Results The efficacy on erythra was better in the experimental group than that of control group P<0.05. Conclusion The wet compress with flos lonicerae is effective,safe and economical for the treatment of cetuximab correlative erythra,which is deserved to be applied in clinical practice.

Objective To investigate the relationship between cardiac vagus nerves and changes of connexins(Cx)and intracellular gap junction(GJ)distribution pattern in superior vena cava(SVC)myosleeve in dog with atrial fibrillation(AF).Methods Twenty four hybrid dogs were divided into sham operation group(Sham group,n=8),SVC-AO fat pad removed group(RM group,n=8)and SVC-AO fat pad reserved group(RS group,n=8).In RM group and RS group,right atrial pacing was performed at a frequency of 500～650/min for 6 weeks to establish AF model.AF was induced by programmed stimulation or burst stimulation of atrial pacing.The expression and distribution of Cx40 and Cx43 in the SVC myosleeve tissue in three groups were analyzed by immunofluorescence staining.Transmission electron microscopy was used to observe the uhrastructural organization of gap junction(GJ).Results The rate of inducing sustained AF(＞ 15 min)in RS group was significantly higher than that in RM group (P ＜ 0.01).The expression of Cx40 and Cx43 in the SVC myosleeve in sham group and RS group were significantly higher than that in RM group(P ＜ 0.05).Furthermore,the expression of Cx40 and Cx43 in RS group were obviously higher than that in sham group(P ＜0.05).The ratio of end-to-end to side-to-side in RS group was lower than that in Sham group and RM group.Comparing with RM group,the channel of GJ became shorter and wider in RS group(P ＜0.05).Sarcomere was dissolved and mitochondrion showed vacuole degeneration in RS group.Conclusion The remodeling of Cx40 and Gx43 in SVC myosleeve tissue may be mediated by vagus nerves.It is conducive to the maintenance and stability of AF.However,this effect can be weakened by removing SVC-AO fat pad of canine.

Objective:To evaluate the clinical outcomes of patients after intensity modulated radiation therapy (IMRT) for hepatocellu-lar carcinoma (HCC) with portal vein tumor thrombosis (PVTT) or inferior vena cava tumor thrombosis (IVTT). Methods:A registry data-base of 41 patients treated with IMRT for HCC with PVTT or IVTT in Radiotherapy Center of No.3 Hospital of Beijing Chinese People Armed Police Forces between January 2013 and May 2015 were analyzed retrospectively. The biological effective dose of radiation was ranged 48-94Gy. Short-term effects and prospective efficacy were observed. Log-rank test, Cox regression were used for survival analysis and prognostic factor identification. Results: Grade 2 or higher level gastrointestinal reaction was observed in 12 patients (29.3%). Hematological toxicity was observed in 11 patients (26.8%), and radiation-induced liver disease was observed in 6 patients (14.6%). We found that 29.3%of patients achieved a complete response and 31.7%of patients achieved a partial response. The stable and progressive disease rates were 39.0%and 0.0%, respectively. Median patient survival was 11 months, and the 1-year survival rate was 34.1%. The significant independent variables associated with the overall survival included Child-Pugh grade, AFP test, and CHE lev-el. Conclusion:IMRT is a safe and effective treatment for PVTT or IVTT in patients with HCC.

Objective: To investigate the clinical efficacy of acupuncture combined with tuina in treating patients with cervical vertigo. ＜br> Methods: According to the principle of randomization, 258 cases with cervical vertigo who met the inclusion criteria for the study were randomly divided into an observation group and a control group, with 129 cases in each. The patients in the observation group received acupuncture combined with tuina therapy, while those in the control group were just treated by the same acupuncture therapy as in the observation group. After 10-day continuous treatments, the clinical efficacies of the two groups were analyzed and compared. ＜br> Results: The total effective rate of the observation group was 100%, versus 86.0% of the control group, and the difference was significant (P＜0.05). After treatment, cervical range of motion (ROM) scores in both groups were statistically significantly different from those before treatment (allP＜0.05); in addition, there was a statistically significant difference in inter-group comparison of ROM score (P＜0.05). ＜br> Conclusion: Compared with simple acupuncture treatment, acupuncture combined with tuina therapy has a better effect in improving the ROM of cervical vertigo patients, with higher clinical efficacy.

Phthaloyl dichloride (1)was reacted with LiAlSeH2 to give benzo[c]selenophene-1;3-dione (2);which was treated with the Grignard reagents to generate hydroxyl compounds 3a-3h.These compounds were finally converted to target products 4a-4h by treatment with hydriodic acid.The structures of 4a-4h were confirmed by MS and 1 H NMR.Their inhibitory activity against adenosine diphosphate (ADP)-induced platelet aggregation was evaluated by Born′s turbidimetric assay;free radical scavenging activity was assayed by xanthine oxidasemethod and 1;10-phenanthroline spectrophotometric method.It was found that compound 4 f displayed more potent inhibi-tory effect on platelet aggregation than 3-n-butylphthalide and comparable hydroxyl free radical scavenging activity in vitro to that of edaravone.Therefore;compound 4 f might be the candidate for further investigation.
