Objective:To evaluate the predictive value of pretreatment platelet-to-lymphocyte ratios (PLRs) in response to neoad-juvant chemotherapy and prognostic outcome in patients with International Federation of Gynecologists and Obstetricians (FIGO) Stag-es IB2-IIB cervical cancer. Methods:An investigation was conducted from January 2010 to December 2012 on 75 patients with FIGO Stages IB2-IIB cervical cancer, who underwent neoadjuvant chemotherapy and radical surgery in Changhai Hospital, Shanghai. A re-ceiver operating characteristic (ROC) curve was used to determine the best PLR cut-off value in predicting the response to neoadjuvant chemotherapy. The relationships between the pretreatment variables and the response to neoadjuvant chemotherapy were assessed in univariate and multivariate settings. The overall three-year survival rates were analyzed using the log-rank test and Cox regression mod-el. Results:The response to neoadjuvant chemotherapy was associated with PLR. At the threshold of 123.0, the PLR was 88.5%sensi-tive and 52.2%specific. Multivariate analysis showed that the low independent PLR predicted the response to neoadjuvant chemothera-py well. Based on the log-rank test, the three-year survival rate was lower in patients with PLR >123.0 than those with PLR <123.0 (59.8%vs. 82.4%), but no statistically significant differences were observed between them (P=0.116). Mono-factorial analysis showed that vascular invasion (a tumor that is>4 cm in diameter) and lymph node metastasis influenced the three-year survival rate. In the Cox regression model, only the lymph node metastasis was identified as an independent risk factor for poor prognosis (RR:5.375;95%CI:1.351-21.379; P=0.017). Conclusion: Pretreatment PLR is an easily measured, reproducible, and inexpensive marker of systemic in-flammation and thus shows a prognostic and independent predictive value for the response to neoadjuvant chemotherapy in cervical can-cer. However, pretreatment PLR is not a clinically significant factor for the assessment of cervical cancer prognosis.

The effects of pioglitazone on the expressions of hypoxia-inducible factor-1 α (HIF-1 α) and vascular endothelial growth factor (VEGF) in renal tissues of diabetic rats were observed. Diabetic rat model was established by feeding high-carbonhydrate-fat diet and injecting streptozotocin. After the treatment with pioglitazone, the kidney index, 24 h urinary albumin, blood urea nitrogen, serum creatinine, fasting blood glucose, fasting insulin, homeostasis model assessment for insulin resistance (HOMA-IR), total cholesterol,triglycerides, and low-density lipoprotein-cholesterol of diabetic rats were significantly lower than those of untreated ones, high-density lipoprotein-cholesterol was increased, the expressions of HIF-1α and VEGF in renal tissue were decreased ( all P<0. 01 ). It suggested that pioglitazone may improve renal function and the balance of glucose-lipid metabolism in diabetic rats via down-regulating HIF-1/VEGF pathway.
