Objective To investigate the expression of thymidylate synthase (TS) in bladder urothelial carcinoma(BUC) and its clinical significance, and to evaluate its prognostic value, thus to help predict the prognosis and choose therapy protocal. Methods The expression of TS was assessed by immunohistochemistry in 54 BUC and 15 normal bladder specimens, and all these clinical data were retrospectively analyzed after surgery. Expression of TS,clinicopathologic findings and two prognostic variances (relapse-free survival (RFS) and overall survival (OS)) were determined. The prognostic value of TS was estimated by survival curve and Cox proportional hazards model. Results Immunohistochemistry showed that 25 of 54 BUC cases (46. 30%) had high TS expression. In these cases,there was 29. 41%o (5/17) for G1 ,46. 43% (13/28) for G2,77. 78% (7/9) for G3 ;21.43% (3/14) for Ta, 26. 32% (5/19) for T1, 86. 67% ( 13/15 ) for T2,66.67% (2/3) for T3,66.67% (2/3) for T4. Expression of TS was positively associated with the grade and stage of carcinorma ( Kruskal - Wallis H, P = 0. 0 3 and P ＜ 0. 0 0 1 ). The recurrence and case - fatality of patients with high TS expression was 60. 00% (15/25) and 44. 00% (11/25) ,respectively. The survival analysis and Cox regression analysis showed that expression of TS were independent predictor for recurrence ( RR = 2. 65,95% CI was 0.80～8.81,P＜0.05) anddeath (RR=1.42,95%CIwas0. 36～5.58,P＜0. 05). Conclusions The probability of BUC progress and recurrence increases with the increasing of TS expression. Detection of TS expressing level can contribute to select appropriate treatment and follow-up schema.

Objective To identify the existence of chromosome 9 open reading frame 72 (C9ORF72) intermediate hexanucleotide (GGGGCC) repeat expansions as well as the mutation-related clinical phenotypes in familial amyotrophic lateral sclerosis (fALS) population from mainland China.Methods DNA samples and clinical data of 62 fALS cases were collected,then the pathological GGGGCC repeat expansions were detected.Haplotype analysis for 20 single nucleotide polymorphisms (SNPs) was performed finally.Results The C9ORF72 intermediate repeat expansions were found in one fALS patient (1.61％,1/62),and repeat number was 24.In addition,2 siblings of this fALS patient also had a 24 repeats allele.These 24 repeat alleles were associated with the pathogenic founder haplotype.Conclusions This study illustrates the existence of the C9ORF72 intermediate repeat expansions in fALS population from mainland China for the first time.An intermediate repeat length in C9ORF72 is related to fALS in mainland China.

This experiment was based on a full-length SAMDC sequence from the drought stress induced cDNA library of Cleistogenes songorica.Two methods,absolute quantification and relative quantification,were used to analyze the gene expression under different tissue and drought stress treatment by real-time quantitaive PCR experiments and were compared each other,while CsSAMDC gene was used as a case.Leaves and roots tissue were sampled from the plants at 0,4,6,8,and 10 d of drought stress and 1 and 4 d after rewatering.The 2-CT method was used to analyze the relative changes in gene expression from quantitative real-time PCR experiments.A standard curve was generated by the purified plasmid DNA.The primer concentration in the realtime PCR was optimized.All absolute quatification data were normalized by the normalization factor from the most stable house-keeping genes in C.songorica.Relative quantification results using 2-CT method showed that CsSAMDC transcripts increased 5.93?0.71 fold in roots,down regulated 0.62?0.13 fold in leaves,under drought stress.Absolute quantification results showed that CsSAMDC transcripts up-regulated in roots significantly under drought stress as 1ong as 8 to 1 0 days after drought stress,while down-regulated in both roots and leaves after drought stress within 6 days and 1 to 4 days after rewatering,compared with control.CsSAMDC transcipt showed similar tendency of gene expression compared by using relative and absolute quantification methods.

Objective To explore the effects of Compound Malt Pill on gene expressions of androgen receptor (AR) and insulin receptor (INSR) in polycystic ovarian syndrome (PCOS) rats; To discuss its relevant mechanism of action.Methods Letrozole was used to induce and establish rat models. Rats were randomly divided into normal group, model group, Diane-35 group, low-, medium- and high-dose Compound Malt Pill groups. The normal group and model group received normal saline by gavage; the Diane-35 group was given Diane-35 by gavage; Compound Malt Pill groups were respectively given different concentrations by gavage for 21 d. The levels of serum testosterone (T) and insulin were measured by ELISA, and the gene expressions of AR and INSR were measured by RT-PCR. Results Compared with normal group, the serum T, insulin and the gene expressions of AR and INSR in model group increased significantly (P<0.05,P<0.01); compared with model group, the serum T, insulin and the gene expressions of AR and INSR in low-, medium- and high-dose Compound Malt Pill groups decreased significantly (P<0.05, P<0.01).Conclusion Compound Malt Pill can adjust endocrine-metabolic disorder in PCOS rats.

Objective To investigate the effect of fusidic acid cream on inflammatory reaction caused by skin barrier damage.Methods Eight male SKH-1 hairless mice were included in this study.The back of each of these mice were equally divided into six regions measuring 1 cm × 2 cm in size,which were then assigned into six groups:blank control group remaining untreated,barrier-impaired group,barrier-impaired and fusidic acid-treated group,barrier-impaired and vehicle-treated group,barrier-unimpaired and fusidic acid-treated group,barrierunimpaired and vehicle-treated group.Stratum corneum was removed by adhesive tape stripping to establish an animal model of acute skin barrier damage in the corresponding skin regions of these mice,and fusidic acid cream or vehicle was topically applied to the corresponding regions once.Twelve hours later,skin surface swab samples were collected from the back of these mice followed by bacterial culture and colony counting.Mice were then sacrificed,and skin tissue specimens were resected from these mice,and subjected to real-time fluorescence-based quantitative PCR for the measurement of the mRNA expressions of myeloid differentiation factor 88 (MyD88),interleukin-1α (IL-1α),IL-6,epidermal antibacterial peptides S100a8 and S100a9.Statistical analysis was carried out by repeated-measures analysis of variance (ANOVA) and least significant difference (LSD) test.Results The mRNA expressions of MyD88,IL-1α,IL-6,S100a8 and S100a9 were all significantly higher in the barrier-impaired group than in the blank control group (all P ＜ 0.05).Specifically,the mRNA expression level of MyD88 in the barrier-impaired group was 8 times that in the blank control group (8.3 ± 3.0 vs.0.8 ± 0.4).Compared with the barrier-impaired group,the barrier-impaired and fusidic acid-treated group showed a significant decrease in the mRNA expressions of IL-1α (2.8 ± 0.3 vs.20.1 ± 10.0,F =47.11,P ＜ 0.01),IL-6 (1.6 ± 2.3 vs.9.4 ± 4.0,F =16.18,P＜ 0.01),S100a8 (1.5 ± 1.4 vs.5.0 ± 1.6,F=59.71,P＜ 0.05) and S100a9 (1.2 ± 0.7 vs.3.4 ± 1.6,F=21.94,P ＜ 0.05).Conlusions Fusidic acid cream could attenuate the inflammatory reaction caused by acute skin barrier damage,which might partly explain its action mechanism in the treatment of inflammatory skin diseases.
