Objective:To investigate the correlation between preoperative blood platelet-to-lymphocyte ratio (PLR) and clinico-pathological features, as well as the effect of PLR on the prognosis of non-small cell lung cancer (NSCLC) patients after surgical resec-tion. Methods:Retrospective analysis was performed for 255 cases with histologically confirmed NSCLC that underwent curative re-section from January 2004 to December 2007. All patients were classified into two groups based on the median value of PLR. The rela-tionship between PLR and clinicopathological features was studied. Univariate and multivariate analyses were performed to assess the prognostic effect of preoperative PLR. Results:The median value of preoperative PLR was 130 (range:45.45 to 272.66). Based on the cut-off value of 130, all patients were divided into two groups:low PLR (≤130, n=127) and high PLR (>130, n=128). PLR was corre-lated with tumor site, T stage, and clinical stage. Five-year survival rates of low and high PLR patients were 49.6%and 33.6%, respec-tively, which indicated a statistically significant difference (χ2=12.577, P<0.001) between the two groups. Univariate analysis showed that smoking status, histological differentiation, clinical stage, T stage, N stage, postoperative adjuvant therapy and PLR were associat-ed with survival (P<0.05 for all). Multivariate analysis identified N stage, postoperative adjuvant therapy, and PLR as independent prog-nostic factors of all the patients. In addition, stratified analysis showed that the five-year survival rate of the low PLR group was higher than that of the high PLR group with or without lymph node metastasis, and the differences were statistically significant (P=0.020 and 0.037). Conclusion:An elevated blood preoperative PLR indicates poor prognosis in NSCLC patients. Preoperative PLR is an indepen-dent prognostic factor of NSCLC after curative resection.

Objective To explore the effect of iliac bone flap combined with cancellous bone graft in the treatment of traumatic avascular necrosis of the femoral head (TFHIN). Methods The patients were treated with iliac bone flap and cancellous bone graft. The operation time, intraoperative blood loss, fracture healing time, follow-up time and the postoperative complications were recorded.The degree of hip movement (flexion, external rotation, internal rotation, abduction and adduction) was recorded;the hip functions of patients with different stages were analyzed;the long-term curative effect of postoperative was analyzed. Results The operation time was (68.36 ± 6.81) min, intraoperative blood loss was(93.65 ± 10.42)ml, fracture healing time was(4.31 ± 1.25)months, follow-up time was 35-62 (48.92 ± 2.61)months, and the postoperative complication was 1.42%(3/212).The scores of hip function were significantly improved in each postoperative stage, joint flexion, external rotation, internal rotation, abduction and adduction range was significantly expanded: (94.86 ± 12.37)° vs. (118.24 ± 15.25)°, (32.07 ± 10.34)° vs. (43.64 ± 10.82)°, (28.33 ± 9.61)° vs. (33.41 ± 11.85)°, (19.44 ± 8.37)° vs. (24.36 ± 7.65)°, and the differences were statistically significant (P<0.05). At the last follow-up, the total excellent and good rate of hip function recovery was 88.74%(205/231).The stability rate of imaging was 80.09%(185/231). Conclusions In patients with TFHIN, treatment with the iliac bone flap pedicled with cancellous bone could the blood pressure of the femoral head, restore the blood supply to the damaged site, participate in the bone induction, and improve the hip movement and function,which has a good effect.
