RESUMEN
Objective To investigate the change pattern of perioperative plasma D-dimer levels in patients with lung cancer, and the relationship between plasma D-dimer level and clinical pathological features thereof. Methods A to-tal of 64 patients with lung cancer were taken as cancer group, and 15 cases of benign lung disease were used as control group. The plasma levels of D-dimer were determined 2 days before operation, 1 day, 5 days and 9 days after operation in two groups. The clinical pathological parameters and type of surgery were evaluated at the same time. Results Plasma D-dimer levels were significantly higher in patients with lung cancer than those in control group (t=3.087, P<0.05). D-dimer levels were significantly lower in patients of TNM stageⅠthan those in patients of stageⅡorⅢ(P<0.05, respectively). Plas-ma D-dimer levels were significantly higher in patients with small cell cancer than those of patients with non-small cell can-cer (P<0.05). The perioperative plasma levels of D-dimer changed with time trends (P<0.001). In cancer group, D-dimer levels increased on the first day after operation, and then significantly decreased on the fifth and ninth day after operation (P<0.05). In control group, D-dimer levels increased on the first day after operation. The level of D-dimer was the same lev-el on the fifth day and the first day after operation (P=0.174). The level of 9 days after operation decreased to the level before operation (P=0.631). There was significant difference in overall data between cancer group and control group (P=0.005). D-dimer levels were significantly higher in cancer group than those of control group except for the fifth day after operation. Con-clusion Plasma D-dimer levels were much higher before operation in patients with lung cancer than those of controls. Plas-ma D-dimer levels were associated with TNM stage and cell type. D-dimer levels were significantly increased from the first day after operation, and then decreased significantly until the 9-day after operation, which were lower than that before opera-tionin lung cancer patients. But the level was still higher than that in patients with benign lung diseases.
RESUMEN
Objective To explore the treatment and clinical characteristic of posterior mini-incision surgery for the single segment of the lumbar disc herniation.Methods Clinical data of 260 cases with single segment lumbar disc herniation were analyzed retrospectively.Results Follow-up for 6 months to 5 years,with an average of 24 months.According to Nakai effect criteria,109 cases of excellent,good in 132 cases,17 cases of fair,two cases of poor,12 cases of cerebrospinal fluid leakage,2 cases of wound hematoma,one case of vertebral space infection,resulting in 92.7%.Conclusion Advantages of posterior mini-incision surgery for the single segment of the lumbar disc herniation are small incision,less trauma,shorter operative time,less bleeding,quick recovery and low costs.Stressed the need to accuratel position preoperation.
