Bladder cancer is the most common malignant solid tumor in urinary system. More than 75% cases of bladder cancer have been diagnosed as non-muscle-invasive bladder cancer ( NMIBC ) . Transurethral resection of bladder tumor ( TURBT ) is the standard method for the diagnosis and treatment for bladder cancer, however, due to its problem of recurrence, adjuvant intravesical therapy with either immunotherapy or chemotherapy has been used to reduce recurrence and achieve better efficacy for the patients in appropriate stages. The review focused on current progress in chemotherapy agents, targeted bladder drug delivery systems and treat-ment strategies for NMIBC, which would provide guidance for clinical intravesical chemotherapy.

Objective To study the antidepressant effect of total timosaponin(TT)and its mechanism.Methods The antidepressant effect of TT was examined by mice forced swimming test(FST),learned helplessness(LH)experiment,chronic mild stress(CMS)model,yohimbine induced lethality test and 5-HTP induced head-twitches test.Results TT(25 or 50 mg?kg-1,ig,qd?14 d)markedly shortened the immobility time in the FST,but didn't affect the autonomic activity.TT(12.5,25 or 50 mg?kg-1,ig,qd?14 d)significantly decreased the number of escape deficits in the LH mice.TT(25 or 50 mg?kg-1,ig,qd?21 d)markedly enhanced the locomotor activity and increased consumption of sucrose solution in CMS mice.TT(50 mg?kg-1,ig,qd?14 d)enhanced the mortality of mice after administration of yohimbine for 4 h,and distinctly increased the head-twitch number in the 5-HTP induced head-twitches test.Conclusion TT has antidepressant effects in various depression mouse models.Its mechanism may be related to the reinforcement of NE and 5-HT nerves system.

OBJECTIVE:To provide reference for clinical individual medication of voriconatole. METHODS:The distribution of MIC of voriconazole to Aspergillus fumigatus and Candida albicans were summarized as well as the pharmacokinetic parameters of voriconazole in different populations. Using probability of target attainment(PTA)and cumulative fraction of response(CFR)as indexes,crystal ball software 11.1.2.4 was used for Monte Carlo simulation of different dosage regimens of same population and same dosage regimen of different populations. RESULTS:For children with impaired immunity,when the drug doses of were 4,6 mg/kg and MIC was lower than 0.125 mg/L,PTA was higher than 90%;when the drug doses was increased to 8 mg/kg and MIC was lower than 0.125 mg/L,PTA was higher than 90%. For different populations receiving same dosage regimens(4 mg/kg),MIC of teenagers with impaired immunity was lower than 0.25 mg/L and those of healthy adults,patients underwent hematopoietic stem cell transplantation and adults with impaired immunity were all lower than 0.5 mg/L,PTA was higher than 90%. CFR to A. fumigatus were 42.53%,58.41%,77.74%,70.16%,89.40%,93.72%,95.42% and CFR to C. albicans were 96.68%,97.13%,97.94%, 97.54%,98.07%,98.28%,98.35%among children with impaired immunity receiving different drug doses(4,6,8 mg/kg)and dif-ferent populations receiving drug dose of 4 mg/kg(teenagers with impaired immunity,healthy adults,patients underwent hemato-poietic stem cell transplantation,adults with impaired immunity). CONCLUSIONS:Various dosage regimens of different popula-tions included in this study could effectively control C. albicans infection. It is necessary to increase the drug dose of children and teenagers with impaired immunity in order to meet the needs of A. fumigatus infection treatment.

Objective To observe the effect of silencing Snail gene on the invasion and proliferation ability of human pancreatic cancer cell line PANC1.Methods Lentiviral vectors that can express small hairpin RNA(shRNA) targeting human Snail gene(shRNA-Snail) or shRNA sequence that did not match any known mRNA(shRNA-NC) were constructed,and transfected into PANC1 cells.Untransfected cells served as control.mRNA and protein expression of Snail,α-smooth muscle actin (α-SMA) and E-cadherin was determined by real time quantitative PCR and Western blotting,respectively.In vitro invasion ability was tested by Transwell model.Proliferation ability was measured by CCK-8 assay.Results Compared with those in shRNA-NC group,Snail mRNA (0.27 ± 0.02 vs 0.92 ± 0.03) and protein level (0.26 ± 0.02 vs 0.80 ± 0.02),and α-SMA mRNA (0.33 ±0.04 vs 0.97 ±0.07) and protein level (0.31 ±0.04 vs 0.74 ±0.06) in shRNA-Snail group were obviously decreased,but E-cadherin mRNA (1.57 ± 0.45 vs 0.95 ± 0.08) and protein level (0.86 ± 0.03 vs 0.20 ± 0.03) were greatly increased.The number of cells permeating the septum of transwell [(6.80 ± 0.73)/400 magnification vs (26.80 ± 2.52)/400 magnification,P ＜0.01] was significantly decreased,and cell proliferation was inhibited (0.74 ± 0.05 vs 1.47 ± 0.04,P ＜ 0.01).All the differences above were statistically significant (all P ＜ 0.01).No significant differences were observed between shRNA-NC and normal control group.Conclusions Silencing Snail gene may restrain the invasion and proliferation ability of PANC1 cells to a certain degree.

Objective: To explore the application value of MRI quantitative analysis in evaluation on therapeutic effect of rheumatoid arthritis (RA) of the wrist. Methods: Totally 30 patients with RA after regular treatment for 1 year were enrolled. The wrist joint was scanned before and after treatment, and the volume of synovitis and bone marrow edema before and after treatment were measured by using the quantitative analysis software. The erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and disease activity score of 28 (DAS28) were also obtained. Changes of synovitis, bone marrow edema, CRP, ESR and DAS28 were analyzed before and after treatment, correlation analysis was performed on the changes of synovitis and bone marrow edema with changes of CRP, ESR and DAS28. Results: After treatment, the volume of synovitis, the range of bone marrow edema, CRP, ESR and DAS28 of the patients reduced significantly (all P<0.05). Synovitis was strongly correlated with changes in bone marrow edema (r=0.61, P<0.01). Changes in synovitis and bone marrow edema were not significantly correlated with those of ESR and CRP (all P>0.05), while changes in synovitis and bone marrow edema were moderately correlated with changes of DAS28 (r=0.50, 0.56, P=0.01,<0.01). Conclusion: MRI quantitative analysis can be used as accurate and Objective: quantitative indices for monitoring and evaluating therapeutic effect of RA.

Objective:To verify the determination method of iodine in serum by inductively coupled plasma mass spectrometry (ICP-MS) and to evaluate the consistency between ICP-MS and As 3+-Ce 4+ catalytic spectrophotometry in determination of serum iodine. Methods:Serum iodine concentration was determined by ICP-MS, 187Re was used as an internal standard, and ralated parameters were optimized. Eighty-eight serum samples were simultaneously determined by ICP-MS and As 3+-Ce 4+ catalytic spectrophotometry, and the evaluation indexes included determination range of standard curve, detection limit, precision, accuracy. In addition, we also evaluated the consistency of the two methods through inter-group correlation analysis, intra-group correlation coefficient analysis, Passing-Bablok regression and Bland-Altman analysis. Results:The linear range of ICP-MS standard curve was 0 - 300 μg/L. There was a good linear correlation between iodine concentration value and iodine response value, and the correlation coefficient range was 0.999 8 to 0.999 9. The detection limit of the ICP-MS method was 1.96 μg/L. The relative standard deviation ( RSD) ranged from 0.2% to 1.4% and from 0.4% to 1.8% for intra and inter-batch precision tests of serum samples. The recovery rate ranged from 90.44% to 108.71%. The correlation analysis of 88 serum samples showed that there was a good correlation between the two methods ( r = 0.934, P < 0.05), and the intra-class correlation coefficient was 0.932. The results of Passing-Bablok regression showed that there was no significant difference between the two methods ( P > 0.05). Bland-Altman diagram suggested that the results of the two methods were consistent. Conclusions:ICP-MS method has low detection limit, high precision and accuracy. ICP-MS method is simple, rapid, easy and suitable for determination of iodine in large quantities of serum samples. The results of the two methods for determining serum iodine are consistent.

Objective To evaluate MRI diagnostic value for single lesion characteristics in the splenium of corpus callosum.Methods MRI features,clinical data,and parts of follow-up results of 9 cases with single lesion in the splenium of corpus callosum were analyzed retrospectively.Results (1)Clinical manifestations:headache and dizziness occurred in 4 cases,syncope in 3 cases,fever in 2 cases, physical activity barriers in 2 cases.(2)Clinical diagnosis:hypoglycemic encephalopathy were rescaned one month later in 3 cases, in which the previous lesion completely disappeared.Clinical experience of encephalitis were improved after treatment in 2 cases. Cerebral infarction,epilepsy,brain injury and degeneration were diagnosed respectively in each one case,in which lesion still existed after treatmented.(3)Image findings:despite the different clinical manifestations,image features of all cases were quite similar. Round or foliated like lesions of slightly long T1 and long T2 signals in the splenium of corpus callosum were presented in all cases. High signals on diffusion weighted imaging and low signals on the ADC were showed with same lesions,andno obvious enhancement after contract media injected was seen.Conclusion Single lesions in the splenium of corpus callosum are showed in many diseases. The image features of hypoglycemic encephalopathy or encephalitis have certain characteristics (single lesion is reversible).Accurate diagnosis need to combine with clinical data and medical history.
