Objective To investigate the predictive value of combined analysis on single nucleotide polymorphisms (SNPs) of X-ray cross-complementing1 ( XRCC1 ) gene 194 and 399 codon,xeroderma pigmentosum group D (XPD) gene 312 codon and glutathione S-transferase P1 (GSTP1) gene 105 codon in platinum based chemotherapy.Methods Direct sequencing was performed to detect XRCC1,XPD and GSTP1 genotypes in peripheral blood from 50 cancer patients receiving platinum-based chemotherapy.Genetic polymorphisms of these genes related to sensitivity of platinum were reviewed.Results Favorable genotypes were Arg/Trp and Trp/Trp in XRCC1 194 codon,Arg/Arg in XRCC1 399 codon,Asn/Asn in XPD 312 codon and Val/Val in GSTP1 105 codon.The response rate to chemotherapy was 57.1％,75.0％,60.9％,85.7％ and 87.5％,respectively.The response rate for patients possessing ≥2 favorable genotypes and those possessing 1 or 0 favorable genotype was 78.9％,36.4％ and 0,respectively.Patients possessing ≥2 favorable genotypes demonstrated higher sensitivity to platinum based chemotherapy,compared with those possessing 1 or 0 favorable genotype ( x2 =25.79,P ＜ 0.01 ).Conclusions Combination analysis of genomic polymorphisms of XRCC1,XPD and GSTP1 may be useful in predicting sensitivity of platinum based chemotherapy.

ObjectiveTo explore the cause of early death (death within 3-12 months after hemodialysis) and the related influencing factors patients undergoing maintenance hemodialysis (MHD) as to provide a scientific basis for the prevention of early death.Methods A retrospective matched controlled study was conducted. Fifty-one patients who underwent MHD from January 2004 to April 2014 and died within 3-12 months after hemodialysis in hemodialysis center of the 174th Chinese People's Liberation Army Hospital were included in the case group by retrospective analysis method. According to 1∶2 matched controls, 102 patients underwent hemodialysis in the same period (±2 months) and survived over 12 months were selected as control group. All patients received regular hemodialysis (dialysis 2-3 times per week), with conventional limitation of water and sodium intake, routine treatments such as control of blood pressure, treatment of anemia and disorders of calcium and phosphorus contents. Causes of short-term death were analyzed. Clinical and biochemical parameters of two groups were collected when dialysis was started, and the single factor and multiple factors logistic regression was used to analyze the related risk factors when dialysis was started. Receiver operating characteristic curve (ROC) was plotted to evaluate the value of above parameters in predicting the early death in patents with MHD.Results The main causes of early death of 51 patients with MHD were mainly cardiovascular and cerebrovascular diseases (27 cases, 52.9%), and infections (15 cases, 29.4%). It was shown by single factor analysis that the age [odds ratio (OR) = 6.625, 95% confidence interval (95%CI) = 3.232-13.580,P = 0.000], diabetes (OR = 3.875, 95%CI = 0.654 - 10.622,P = 0.031), specialist intervention time before dialysis (OR = 0.349, 95%CI =0.287 - 0.572,P = 0.004), the emergence of cardiovascular and cerebrovascular events before dialysis (OR = 9.667, 95%CI = 4.632 - 20.174,P = 0.000), the first dialysis for emergency dialysis (OR = 3.875, 95%CI = 1.713 - 8.765, P = 0.005), blood albumin level (OR = 0.294, 95%CI = 0.068 - 0.550,P = 0.008), leukocyte count (OR = 6.286, 95%CI = 1.648 - 23.982,P = 0.026), neutrophil count (OR = 2.833, 95%CI = 1.630 - 4.923,P = 0.001) might be the factors correlating with early death. Eight independent factors were statistically significant, and their effect on the MHD patients was analyzed by logistic regression analysis inα = 0.05 level. The results showed that patients with old age (OR = 1.054, 95%CI = 1.019-1.090,P = 0.002), and the emergence of cardio-cerebrovascular events (OR = 7.469, 95%CI = 2.474 - 22.545,P = 0.000)were early death risk factors of MHD patients, and early specialist intervention before dialysis was a protective factor (OR = 0.286, 95%CI = 0.113-0.722,P = 0.008). ROC curve showed that age had moderate diagnostic value for early death of MHD [area under ROC curve (AUC) = 0.756], the cut-off value was 59.0 years old, the sensitivity was 66.7%, and the specificity was 77.5%. The diagnostic value of early specialist intervention before dialysis was relatively low (AUC = 0.367), the cut-off value was 0.875 years, the sensitivity was 39.2%, and the specificity was 33.3%.Conclusion Old age, the emergency of cardiovascular and cerebrovascular events before dialysis is associated with early death, and specialist intervention ahead of dialysis can reduce the risk of early death.

Recently, microRNAs (miRNAs) have been shown to be involved in multiple biological pathways that can influence tumor progression and metastasis and they can serve as prognostic biomarkers in many cancers. The present study examined the prognostic significance of miR-215 in cervical cancer. The paraffin-embedded paired cervical scrape samples and tumor tissue samples from 302 patients with stage II cervical cancer were detected for the expression of miR-215 by using qRT-PCR. A miR-215-based classifier was established by using the Cox regression model. The prognostic and predictive accuracy of this classifier was determined in both the internal testing group of 138 patients, and the external independent group of 280 patients. Moreover, cervical cancer HeLa cells overexpressing miR-215 (HeLa-miR-215) were constructed and subcutaneously injected into the nude mice to examine the effect of miR-215 on tumor growth and metastasis in vivo. The results showed that the expression level of miR-215 was significantly higher in cervical cancer tissues than in paired normal tissues (P<0.0001). When patients were classified into high- and low-risk cancer progression groups according to miR-215 level, the 5-year disease-free survival in high- and low-risk groups were 43% (95% CI: 32.1-51.6) and 67% (95% CI: 48.6-77.3) (hazard ratio [HR] 2.02, 95% CI: 1.16-3.52; P=0.013) respectively. Moreover, the expression level of miR-215 was negatively associated with survival rate in patients at TNM stage T3 (HR: 3.317; 95% CI: 1.18-5.14, P=0.017) and TNM stage T4 (HR: 3.48; 95% CI: 1.49-4.45, P=0.008). Tumor volume in nude mice injected with HeLa-miR-215 cells was significantly larger than that in mice injected with control HeLa cells. It was concluded that the expression level of miR-215 is associated with cervical tumor progression and worse survival rate, suggesting that it may serve as a potential prognostic marker to identify patients at higher risk of recurrence.
