Objective To investigate the effect of antisense inhibitor of telomerase on growth of tumor cells.Methods:Phosphorothioate antisense oligonucleotides (PS-ASON) with sequence TAGGGTTAGACAA which can recognize the RNA template region of telomerase and PS-random primer with 13-nucleotides were incubated with RCZ cell line derived from renal cell carcinoma (RCC).The number of cells was counted from 1 to 43 days,doubling time was calculated and inhibiting rate was determined by MTT method.Results ASON group reduced the number of cells (P<0.01), lengthened doubling time (P<0.005),and elevated the inhibiting rate (P<0.01) compared with random primer control and empty control.The efficacy depended on the dose of ASON (P<0.05) and it was of sequence-selective specificity.Conclusion The ASON targeted to the RNA template has an inhibition effect on the growth of RCZ cell and may have potential significance in tumor therapy.

Objective To explore the influence of salinomycin in the growth, apoptosis and invasion of human bladder cancer 5637 cells,and to clarify its possible mechanism.Methods The human bladder cancer 5637 cells cultured invitro at logarithmic growth phase were divided into control group and different doses of salinomycin(15, 30 and 60μmol·L-1 )groups.The inhibitory rate of the growth of 5637 cells in various groups was measured by MTT assay. Flow cytometry was used to detect the apoptotic rates of 5637 cells in various groups. The invasiveness of 5637 cells was tested by Matrigel Invasion Assay.The expression levels ofβ-catenin protein in 5637 cells in various groups were determined by Western blotting method. Results Compared with control group,the inhibitory rates of growth of human bladder cancer 5637 cells in different doses of salinomycin groups were increased significantly(P<0.05);the apoptotic rates were increased(P<0.05).the number of cells passed the Matrigel was decreased(P<0.05),and the expression level ofβ-catenin protein was decreased (P<0.05).Compared with low dose of salinomycin group,the inhibitory rate of growth of 5637 cells in high dose of salinomycin group was increased(P<0.05);the apoptotic rate was increased(P<0.05),the number of cells passed the Matrigel was decreased (P < 0.05 ), and the expression levels of β-catenin protein was decreased (P<0.05). Conclusion Salinomycin can inhibit the growth of 5637 cells significantly,increase the apoptosis,and decrease the cell invasion;the inhibitory effect may act by inhibiting the Wnt/β-catenin pathway.

The growth changes of glutathione (GSH) and ergosterol in Saccharomyces cerevisiae (CICC1447 and CICC1339) were detected under 0.5Mpa pressure with compressed high-pure air (O-2∶N-2=21∶79). The results showed that logarithmic phases of the two strains were delayed; their biomass and special growth rate were lower than those of control sample (0.1MPa) and the double time were prolonged under 0.5MPa. High-pressure could increase the content of GSH obviously, compared to ambient atmosphere control samples. When the holding time was 3h, the content of GSH and ergosterol in CICC1447 increased 42.6% and 20.1%, respectively. However, the content of GSH in CICC1339 increased 58.7% when the holding time was 6h, while ergosterol content reduced. The results indicated that different yeast strains have different stress-response mechanism to copy with high-pressure shock.

To explore the correlation between nucleated red blood cell (NRBC) count and perinatal asphyxia in neonates.Full-term newborns born from May 2011 to November 2012 were recruited and divided into perinatal asphyxia (n =40) and normal (n =30) groups.Apgar score was recorded immediately at delivery.The umbilical arterial blood was also collected into anticoagulant-treated tube and NRBC was counted by Japan OlympusCX41 biological microscope.NRBC count for perinatal asphyxia group [(10.70 ± 2.61)/100 WBC] was significant higher than that for normal group [(2.67 ± 0.35)/100 WBC].A statistically significant negative correlation existed between NRBC and umbilical arterial blood pH,Apgar score at 1 min,BE value (r =-0.802,P ＜ 0.05 ; r =-0.639,P ＜ 0.05 ; r =-0.566,P ＜ 0.05).Associated with perinatal asphyxia in neonates,NRBC may be used as a simple index for assessing the severity of neonatal perinatal asphyxia.

Objective To explore the outcome of monoclonal gammopathy of undetermined significance (MGUS). Methods The data from 14 MGUS patients in our hospital including clinical features, outcome and change of M protein concentration were analyzed retrospectively. Results The MGUS didn't have the clinical manifestations of multiple myeloma (MM), the time of outcome from MGUS to MM was about 4-20 years (mean time, 10 years). The most types of MM were IgA and IgG, 6 cases were IgA type, 6 cases were IgG type and 2 cases were light chain type. The concentration of immune globulin in general showed an upward trend year by year. A few showed fold lines ascend. Conclusions The elevated monoclonal immunoglobulin may develop into MM after many years. We must follow up frequently to avoid error diagnosis and missed diagnosis.

Objective:To investigate the safety and effect of complete mesocolie excision (CME) combined with arterial infusion chemotherapy (AIC) and intra-peritoneal interstitial sustained-release chemotherapy (IPISRC). Methods:A total of 104 patients were classified under the experimental group and underwent CME combined with AIC and IPISRC. The other 98 patients were classified un-der the control group and only received radical surgery. Pre-and post-operative blood routine examinations, as well as liver and kidney function tests, were conducted for both groups. Post-operative adverse reactions and incidence of complications were recorded. Cancer and para-neoplastic tissues were sampled in experimental group. The post-surgery 5-fluorouracil (5-FU) concentration in the drainage fluid as well as those in the peripheral blood , were determined. Three-year follow-ups were conducted, during which the local recur-rence rate, liver metastasis, progression-free survival rate, and total survival rate were recorded. Results: No significant differences were found in the white blood cell count, hemoglobin count, liver and renal functions of the patients before and after the surgery, and rate of adverse reaction and complications between the two groups after surgery (P>0.05). In experimental group , the 5-FU concentra-tion was significantly higher in the cancer tissues than in the para-neoplastic tissues . The 5-FU concentration in experimental group was also significantly higher in the intra-peritoneal drainage liquid and reached its peak in the peripheral blood on day 3 post-surgery . Local recurrence and liver metastasis rates were significantly lower in experimental group than those in control group, whereas the pro-gression-free and three-year overall survival rates were significantly higher in experimental group than in control group (P<0.05). Con-clusion:The tharepy of pations of experimental goup is safe and effective. This method significantly improves the progression-free and three-year survival rates of the patients as well as significantly reduces the local recurrence and liver metastasis rates of colon cancer.
