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 evaluate the value of susceptibility-weighted imaging (SWI)sequence in the diagnosis of metastatic en-cephaloma pre and after radiotherapy by comparing the appearance of the SWI and contrast-enhanced T1-weighted imaging(T1 WI). Methods Thirty-eight lung cancer patients with brain metastases underwent SWI and contrast-enhanced T1-weighted imaging re-spectively before and 2-3 months after radiotherapy.Evaluated the two methods by score(the score ranged from 0-3,0 represen-ted no showing,1 represented not showing clearly,2 represented could judging,3 represented showing obviously).Results Before radiotherapy,SWI detected 1 61 lesions of metastases and could obviously show tumor vascular in brain metastases (mean score 2.73±0.05).Contrast-enhanced T1 WI detected 1 61 lesions(mean score 1.93±0.04 ).SWI showed significantly higher score than enhanced T1 WI(P <0.05)through paired sample t test.After radiotherapy,SWI found 98 lesions (mean score 1.47±0.1 1 )and en-hanced T1 WI found 140 lesions (mean score 1.80±0.07),enhanced T1 WI had significantly higher score than SWI(P <0.05).Con-clusion SWI is superior to contrast-enhanced T1 WI to show the metastases before radiotherapy and can show tumor vascular in brain metastases obviously.SWI is inferior to enhanced T1 WI after radiotherapy.It has some value and may provide a new method for evaluating effects of radiotherapy.

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 evaluate the protective effect of propofol on liver in severely scalded rabbits.Methods Twenty healthy male New Zealand rabbits, aged 3-4 months, weighing 2.3-2.5 kg, were randomly divided into either scald group (group S, n =10) or propofol group (group P, n =10).Thirty percent of the total body surface was shaved chemically with 10％ sodium sulphate and then exposed to 98 ℃ water for 20 s to produce third degree thermal injury at the back and buttocks of anesthetized rats.In group P, propofol was injected at a dose of 1.5 mg/kg at 1 h after scald, followed by an infusion of 4 mg· kg-1 · h 1 for4 h.The equal volume of normal saline was given in groupS.Before scald (T1), at 1 h after scald (T2) , and at 6, 12 and 24 h after administration of propofol or normal saline (T3-5) , blood samples were taken from the internal jugular vein for determination of serum alanine aminotransferase (ALT) activity (by lactate dehydrogenase method), aspartate aminotransferase (AST) activity (by MDH), and tumor necrosis factor-alpha (TNF-α) concentrations (by enzyme linked immunosorbent assay).The rabbits were sacrificed at T5, and their livers were removed and cut into sections which were stained with haematoxylin and eosin and examined under microscope.Results The serum ALT and AST activities and TNF-α concentrations were significantly higher at T2-5 than at T1.Compared with the values at T2, the serum ALT and AST activities and TNF-α concentrations in group S and serum TNF-α concentrations in group P were significantly increased at T3-5, and no significant change was found in the serum ALT and AST activities at T3-5 in group P.Compared with group S, the serum ALT and AST activities and TNF-α concentrations were significantly decreased at T3 5, and the pathological changes were mitigated in group P.Conclusion Propofol provides protective effect on liver in severely scalded rabbits.

Aim: To investigate the analgesic effect of the new triazole compounds Ⅱ_3 and effects on cycloxygen-ase-1(COX-1) as well as cycloxygenase-2( COX-2). Methods: The hot plate and the stretching settings in mice were utilized to study the effects of compounds Ⅱ_3 on acute pain. Radioimmunologic kits were used to assay the contents of PGE_2 in macrophage and 6-keto-PGF_(1α) in endodermis, which represents the activities of COX-2 and COX-1, respectively. Results: CompoundsⅡ_3( 15,30,60 mg/kg) prolonged the pain liminal value and the writ-hing response time in the initial appearance, and reduced the frequency of the writhing response in 15 min after exposure of the mice to glacial acetic acid( P < 0. 05, P < 0. 01). CompoundsⅡ_3, at the concentrations of 1×10 ~(-5),1×10 ~(-6), and 1×10 ~(-7) mol/L, markedly inhibited the production of PGE_2 in macrophage, and also impeded the activity of COX-2 at 1×10 ~(-6) mol/L But the inhibition of 6-keto-PGFla in endodermis using the same settings of compounds Ⅱ_3 was found to be limited. Conclusion: CompoundsⅡ_3 has analgesic effects on the acute pain and selective inhibition on COX-2.

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.

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.
