Objective To explore the impact of preoperative neoadjuvant chemotherapy on the expressions of multi-drug resistance genes in patients with cervical cancer and its relationship with the effect of chemotherapy. Methods Ninety-eight cervical cancer patients with TP regimen selected to perform preoperative chemotherapy were enrolled in the Affiliated Hospital of Guiyang Medical College between January 2010 and June 2014. Immunohistochemisty (En vision method) was used to determine the expressions of P-gP, GST-π and TopoII of the same patients before and after neoadjuvant chemotherapy and explore the relationship with the effect of chemotherapy. Results The positive expression rates of P-gp and GST-π were 71.43% and 64.29% before chemotherapy and 80.61%and 74.49%after chemotherapy, respectively. The former two had significant differences (P<0.01). The positive expression rates of TopoII was 48.98%before chemotherapy and 28.57%after chemotherapy , respectively, showing significant differences (P < 0.01). The expressions of P-gp, GST-π and TopoⅡ gene were not affected by the clinical and pathological features of cervical cancer (P > 0.05). Before neoadjuvant chemotherapy, the positive expression of GST-π in the ineffective group was statistically higher than that in the effective group (P<0.05). The positive expressions of P-gp and Topo II showed no statistical significance between the effective group and the ineffective group (P > 0.05). There was significant correlation in the expressions of P-gp, GST-π and TopoⅡ(P < 0.05) before and after neoadjuvant chemotherapy. Conclusions The expression of P-gp, GST-πand TopoⅡgene may not be affected by the clinical and pathological features of cervical cancer, but may change expressions of multi-drug resistance genes in cervical cancer by neoadjuvant chemotherapy. Monitoring their expression has a guiding significance for drug selection, prognostic judgment, and the following treatment regimen decision. The GST-π, expression level can be used as a biological parameter to predict the effect of TP regimen neoadjuvant chemotherapy.

ObjectiveTo investigate the rule of changes of the soleus mass and expression of myosin heavy chain (MHC) isoforms mRNA.Methods40 female Wistar rats were divided randomly into the control group and three spinal cord transection (ST) groups, ST7, ST15, and ST30 with 10 animals in each group. Rats in ST groups were subjected to a complete ST between T8 and T10 levels. The right soleus was dissected and weighed at 7, 15, 30 days after ST, and the expression of MHC mRNA isoforms was measured by semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR).ResultsThe Absolute and relative soleus masses in three ST groups were lower significantly than those of control group (P<0.05). The soleus mass in ST15 and ST30 groups were lower than that of ST7 group (P<0.05). The soleus of control group predominantly expressed MHC-I and some MHC-IIa, whereas the soleus began to express MHC-IIx and MHC-IIb after ST, except for MHC-I and MHC-IIa. ST induced consistently down-regulation of MHC-I mRNA and up-regulation of MHC-IIx and MHC-IIa at three time points after ST. The level of MHC-IIb mRNA expression was very low at three time points after ST.ConclusionST can influence the soleus mass at early stage after ST. ST induces a shift toward a faster muscle phenotype from slow to fast MHC isoform. MHC demonstrates plasticity in response to decrease neuromuscular activation.

Objective To evaluate whether estradiol can inhibit and cure the inflammation of experimental preeclampsia in rats. Methods Experimental preeclampsia was induced in 14-day-pregnant rats by infusion of endotoxin (1.0 ?g/kg). Rats with normal pregnancy were infused with sodium chloride solution.A group of preeclampsia rats was injected with 17?-estradiol (17?-E_2, 1 mg?kg -1 ?d -1 ). Blood pressure, albuminuria,inflammation associated adhesion molecule CD_ 49d and tumor necrosis factor-?(TNF-?) were assessed. Results On pregnant day 19, for normal pregnancy group(group C) the blood pressure was (120.4?2.0)mm Hg (1 mm Hg=0.133 kPa),urinary protein (0.47?0.06)mg/24 hours;for experimental preeclampsia group(group A) blood pressure was (134.2?2.4) mm Hg,urinary protein(0.79?0.10)mg/24 hours; for experimental preeclampsia with 17?-E_2 treatment group (group B) blood pressure was(123.3?1.7)mm Hg,urinary protein (0.51?0.08)mg/24 hours. A significant increase of blood pressure and urinary albumin was observed in group A. CD_ 49d expression and TNF-? concentration were also increased. 17?-E_2 reduced the expression of CD_ 49d , concentration of TNF-?,blood pressure and albuminuria of experimental preeclampsia. However, the weight of fetuses in 17?-E_2 treatment group were less than that in other groups. Conclusion 17?-E_2 can improve the symptoms of experimental preeclampsia,but its effects on fetus need to be further studied.
