AIM: To investigate the RNAi effect of the inhibitory member of the ASPP family (iASPP) on the apoptosis of human breast cancer cell MCF-7 which expressed the wild type p53 gene. METHODS: The recombinant plasmid pAd-iASPP-RNAi was transfected into MCF-7 cells. The expression of iASPP mRNA and protein was analyzed by RT-PCR and Western blotting, respectively. The cell apoptosis was detected by FCM, and then the MCF-7 cells were transplanted into nude mice to set up transplantation model. The expression of iASPP RNA and protein in transplanted neoplasm were determined by RT-PCR and Western blotting, the apoptosis index was detected by FCM at the same time. RESULTS: The results showed that the expression of iASPP descended in MCF-7 cells (mRNA 95.4% and protein 96.8%, respectively, P<0.01) and the apoptosis rate and necrosis rate of MCF-7 cells increased (P<0.01) after transfection. As treated with pAd-iASPP-RNAi, the expression of iASPP in transplantation tumor cells descended 87.4% (mRNA) and 89.2% (protein), respectively (P<0.01), and the apoptosis rate and necrosis rate increased accordingly (P<0.01, P<0.05). CONCLUSION: The inhibition of iASPP may resume the ability of p53 to induce apoptosis in breast cancer cells which is able to express wild type p53.

The influence of MRI on severity grading and activity staging in thyroid associated ophthalmopathy (TAO) was evaluated.The results showed that MRI had a higher detection rate in abnormal extraocular muscle than NOSPECS scores(χ~2 = 19.37,P = 0.000).MRI had higher sensitivity,specificity,and accuracy in detection of active TAO than clinical activity score (100% vs 95.7%,88.2% vs 35.3%,96.9% vs 79.7%,respectively).Therefore,MRI improves early detection of atypical grade 4 cases.Signal intensity elevation in adipose suppressed T2WI is helpful to define active stage.

Objective To compare the effects of labor epidural analgesia initiated in latent phase and active phase on parturients and neonates. Methods One hundred twenty nulliparous women at full term (single, head presentation, ASA Ⅰ or Ⅱ ) were randomly divided into 3 groups (n=40 each):control group(group C) ; PCEA initiated in latent phase group (cervical dilatation 0.5-3.0 cm) (group L) and PCEA initiated in active phase group (cervical dilatation＞3.0 cm) (group A). Epidural catheter was placed through L2,3 interspace. 0.1% ropivacaine with fentanyl 2 μg/ml was used for PCEA. A test dose of 5 ml was followed by a loading dose of 10 ml. PCEA device was programmed to allow a bolus of 6 ml with a 30 min lockout interval. The intensity of pain was measured with VAS (0=no pain, 10=worst pain) before analgesia, at 5, 10, 15 and 30 min after beginning of PCEA and cervical dilatation of 7-8 cm and 10 cm. Degree of motor block was assessed by lower extremity muscle strength (modified Bromage scale,0=no motor block, 3=inability to flex ankle joints).Plasma cortisol in maternal venous blood obtained before analgesia and at delivery of fetus and in umbilical cord blood and plasma ropivacaine concentrations in umbilical core blood were determined.The length of every stage, duration of analgesia,delivery mode, the amount of oxytocin used, maternal satisfaction, Apgar scores of the neonates and adverse effects were recorded. Results PCEA initiated in latent phase or active phase significantly reduced VAS score, the plasma cortisol level at delivery, the duration of 1st stage of labor, and the rate of cesarean section and increased the use of oxytocin in L and A groups as compared with group C, but there was no significant difference in the above variables between L and A groups. The duration of analgesia was shorter in group A than in group L. Conclusions Labor epidural analgesia initiated in latent phase or active phase can decrease the rate of cesarean section but does not prolong the duration of labor and is safe for the newborn.
