Telomere maintenance plays a critical role in cancer progression.Approximately 85% human cancer cells maintain their telomere length through activation of telomerase.Other 15%of cancers maintain telomere length independently of telom-erase by alternative lengthening of telomeres (ALT)pathway. Both events are equally important for telomere length mainte-nance of cancer cells.Human telomere consists of a series of G rich DNA sequences,which could form G-quadruplex.The for-mation of this structure can block the extension of telomeres by telomerase or ALT,resulting in cancer cell death.Thereby,G-quadruplex has been one of the focuses of anticancer therapy in recent years.This review focuses on the latest progress of G-quadruplex stabilizers.

Objective To study the repeatability and consistency of normal female pelvic floor structure using transperineal real‐time three‐dimensional ultrasound .Methods Forty‐two cases of normal adult female were evaluated by two different experience operator ,using the real‐time three‐dimensional ultrasound diagnostic apparatus .The bladder neck movement degrees and the levator hiatus area were observed after Valsalva condition .Differences between the groups were compared .Intraclass correlation coefficient (ICC) ,the coefficient of variation (CV) and Bland‐Altman analysis of consistency were evaluated . Results The bladder neck movement degrees and the levator hiatus area measured by the experienced operator (operator 1) and less experienced operator(operator 2) were (18 4.8 ± 5 8.4)cm and (17 7.9 ± 5 4.8) cm ,(17 5.3 ± 3 9.5)cm2 and (17 3.1 ± 4 3.2)cm2 ,respectively .There was no significant difference between the two operators ( P > 0 0.5) .The intra‐ICC were 0 8.9 and 0 9.0 ,CV were 7 2.6% and 3 0.3% .Experienced operator repeatability (ICC= 0 9.9 ,0 9.4) was slightly higher than the less experienced researchers (ICC 0 9.2 ,0 8.1) .The analysis results of Bland‐Altman image showed good consistency between two different operators .Conclusions The current study proves real‐time three‐dimensional ultrasound is a reproducible method for female pelvic floor structure assessment ,and the reproducibility is very well .The detection performance of experienced operator slightly better than the one with less experience ,strengthen the training of junior doctors may further improve the accuracy of measurement .

Objective To investigate the diagnostic parameters,criteria and diagnostic value of pelvic floor ultrasound in female stress urinary incontinence(SUI).Methods Simple factor logistic regression analysis was used to compare the difference of ultrasonic parameters between SUI patients(260 cases) and asymptomatic subjects(60 cases) to find the relevant diagnostic indexes,and to evaluate the diagnostic criteria and diagnostic value by the ROC curve.Results There were significant differences in urethral inclination angle and levator hiatus area in resting and bladder neck position,bladder position,urethral inclination angle,retrovesical angle,levator hiatus area in Valsalva state and urethral rotation angle,bladder neck mobility between the two groups (all P ＜ 0.05).There was no significant difference in age,BMI,bladder neck position,bladder position,retrovesical angle between resting in the two groups (all P ＞0.05).Using the ROC curve analysis,the cut-off points of urethral inclination angle and levator hiatus area in resting,bladder neck and bladder position,urethral inclination angle,retrovesical angle,levator hiatus area in Valsalva,bladder neck mobility and urethra rotation angle to diagnose SUI were 16.5°,13.5 cm2,3.5 mm,0.5 mm,29.5°,139.5°,19.5 cm2,24.5 mm,45.5°,respectively.The sensitivity/specificity were 54.6％/66.7％,49.2％/80.0％,68.1％/95.0％,64.2％/98.3％,67.3％/93.3％,73.5％/50.0％,68.8％/81.7％,70.0％/95.0％,67.2％/85.0％,respectively.The area under the curve were 0.625,0.668,0.855,0.854,0.817,0.622,0.811,0.866,0.817,respectively.Conclusions Pelvic floor ultrasound is a better way to diagnose stress urinary incontinence,and it provides an objective basis for the diagnosis of SUI.

gluconate in both G1 phase and S phase cells.The permeability of G1 phase cells to I-was higher than that in S phase cells,but to gluconate was lower than that in S phase cells.CONCLUSIONS: The density of the volume-activated Cl-current,the anion permeability of the channel and the sensitivity of the current to tamoxifen were different between the CNE-2Z cells in G1 phase and those in S phase.The results suggest that the expression of tamoxifen-sensitive,volume-activated chloride channels is differentiated at different stages of the cell cycle.

AIM:To investigate the type of chloride channel activated by cisplatin in poorly differentiated na -sopharyngeal carcinoma cells (CNE-2Z cells).METHODS:The technique of whole-cell patch-clamp was used to investi-gate the role of Ca 2+in the activation of cisplatin-activated chloride currents and to analyze the effect of hypertonic stress on these currents in CNE-2Z cells.RESULTS:Chloride currents were induced when the cells were exposed to the calcium -free cisplatin solution , showing the similar density to the currents induced by cisplatin with the presence of extracellular cal -cium.However , the latency and the peak time of cisplatin-activated currents in the absence of extracellular calcium were prolonged.The activation of cisplatin-activated chloride currents was insensitive to the depletion of intra-and extracellular calcium.Calcium channel antagonist nifedipine had no effect on the cisplatin -activated chloride currents , while hypertonic solution completely inhibited those currents .CONCLUSION:The cisplatin-activated chloride currents are independent on intra/extracellular calcium .The chloride channels activated by cisplatin are not calcium-activated chloride channels , but are probably volume-sensitive chloride channels .
