Objective:To investigate the clinical application value of argon-helium knife cryoablation combined with radioactive seed implantation in the treatment of non-small cell lung cancer(NSCLC).Methods:A total of 117 patients with NSCLC admitted to Oncology Department of Fifth Affiliated Hospital of Zhengzhou University from January 2015 to January 2017 were included in our study.And they were divided into the combination group(n=63)treated with CT guided argon-helium knife cryoablation combined with radioactive 125I seeds implantation and the control group(n=54)treated only with argon-helium knife ablation.The changes of blood routine indexes, tumor markers, tumor ablation target volume and CT value were observed before and 1, 3, 6 months after treatment.Adverse reactions during treatment and the evaluation results of efficacy were compared between the two groups.Patients were followed up for 24 months to observe the recurrence and survival rates between the two groups. Results:In the combination group, seeds of(12.49±4.91)were implanted, and the X-ray exposure was(123.16±42.75)Gy.There was no significant difference in general clinical data between the two groups before treatment( P>0.05). At 1, 3 and 6 months after treatment, as compared with control group the combination group showed the significantly decreased platelet count( t=3.154, 3.586, 2.233, P=0.027、0.019、0.034), while, there was no significant difference in white blood cell count, red blood cell count and hemoglobin level between the two groups(all P>0.05). The levels of carcinoembryonic antigen(CEA), neuron-specific enolase(NSE)and tumor volume were significantly lower in combination group than in control group at 3 and 6 months after treatment( t3=3.142, 2.926 and 4.281, t6=4.094, 5.382 and 4.535, all P<0.05), showing significant improvements of illness.While, the above levels showed no significant differences at 1 month after treatment between two groups( t=1.065, 1.037, P=0.197, 0.255). At each monitoring time, the CT value of tumor target area showed a steady downward trend( P<0.05). During the treatment, the incidence of thrombocytopenia was higher in the combination group than in the control group(47.6% or 30/63 vs.24.1% or 13/54, χ2=6.935, P=0.008), while there were no significant differences in the incidence of postoperative fever, pneumothorax, myoglobinuria, pain, bleeding and nausea and vomiting between the two groups(all P>0.05). After 6 months of treatment, the remission rate was higher in the combination group(73.0% or 46/63)than in the control group(48.1% or 26/54). The survival time and relapse-free time of the combination group were longer than those of the control group[(21.81±4.31)months vs.(18.93±5.94)months, (20.48±5.76)months vs.(16.93±7.14)months, Log Rank χ2=8.229 and 9.656, P=0.004 and 0.002)]. Conclusions:Argon-helium knife Cryoablation combined with radioactive seed implantation can effectively control the local progression of NSCLC, reduce the risk of tumor recurrence, and has high safety.

Objective To discuss the effect and advantage of the navigation-assisted system in total knee arthroplasty (TKA) of the knees with anatomical abnormality. Methods The study involved five patients with anatomical abnormality of the knees who were treated with arthroplasty under the navigation-assisted system from December 2007 to October 2008. Meanwhile, five patients with normal anatomy of the knees treated with total knee arthroplasty without using the navigation-assisted system were used as control. The α, β, γand δ angles were measured based on the X-ray images and the active range of the knee joint was determined. Results No complication caused by navigation occurred. There was no significant difference in the α, β, γ and δ angles between the two groups, but the range of extremum in the navigation group was less than that of the control group. The mean postoperative active range of the knee joint in the navigation group ( 112.67°) was higher than that of the control group ( 106.98° ), while the preoperative active range of the knee joint of the navigation group [(70.87 ± 10.87)°] was significantly lower than that of the control group [( 105.08 ± 30.67)°]. Conclusions Compared with conventional methods, navigation-assisted TKA showas no obvious advantage in short-term outcome but has great advantages in improving the accuracy and the joint movement, especially for the knees with anatomical abnormality.
