ABSTRACT
Objective To investigate the effect of three-dimensional conformal radiotherapy (3D-CRT)combined with PC chemotherapy (paclitaxel + carboplatin)on non-small cell lung cancer (NSCLC) patients and the serum levels of CA125,tissue inhibitor of metalloproteinase-1 (TIMP-1),serum amyloid A (SAA)and T-lymphocyte subsets. Methods A total of 100 patients with NSCLC treated in Affiliated Hospital of Guangdong Medical University from May 2015 to December 2017 were selected as the study subjects. They were divided into control group and observation group according to random number table method,with 50 cases in each group. The observation group was treated with 3D-CRT combined with PC chemotherapy,while the con-trol group was treated with PC chemotherapy. The two groups were treated for 4 cycles. The therapeutic effect, serum CA125,TIMP-1,SAA,T-lymphocyte subsets and adverse reactions were compared between the two groups. Results Four cases were lost to follow-up both in the two groups. The overall response rate in the observation group (43. 48％,20 / 46)was higher than that in the control group (23. 91％,11 / 46;χ2 = 3. 941, P = 0. 047). The serum levels of CA125,TIMP-1 and SAA of the two groups had no significant difference be-fore treatment,and the levels of these indexes decreased after treatment. The serum levels of CA125,TIMP-1 and SAA in the observation group after treatment were (12. 31 ± 1. 13)U/ ml,(275. 31 ± 13. 69)pg/ ml and (47. 21 ± 7. 21)mg/ L,which were lower than those in the control group [(30. 36 ± 1. 98)U/ ml,(320. 36 ± 17. 23)pg/ ml,(65. 92 ± 8. 36)mg/ L],with significant differences (t = 53. 699,P < 0. 001;t = 13. 884, P < 0. 001;t = 11. 495,P < 0. 001). The levels of CD3 +,CD4 +,CD8 + and CD4 + / CD8 + of the two groups had no significant difference before treatment,and the levels of these indexes decreased after treatment. The levels of CD3 +,CD4 +,CD8 + and CD4 + / CD8 + in the observation group were (35. 27 ± 10. 31 )％, (20. 27 ± 6. 72)％,(15. 89 ± 3. 37)％ and 0. 91 ± 0. 37,which were higher than those in the control group [(30. 77 ± 9. 27)％,(15. 27 ± 5. 73)％,(12. 02 ± 2. 69)％ and 0. 75 ± 0. 39],with significant differences (t = 2. 201,P = 0. 030;t = 3. 840,P < 0. 001;t = 6. 087,P < 0. 001;t = 2. 019,P = 0. 047). There were no significant differences in the adverse reactions such as nausea and vomiting [63. 04％ (29 / 46)vs. 43. 48％(20 / 46);χ2 = 3. 537,P = 0. 060],phlebitis [6. 52％ (3 / 46)vs. 4. 35％ (2 / 46);χ2 = 0. 000,P >0. 999],abnormal liver function [6. 52％ (3 / 46)vs. 2. 17％ (1 / 46);χ2 = 0. 261,P = 0. 609]and myelo-suppression [8. 70％ (4 / 46)vs. 6. 52％ (3 / 46);χ2 = 0. 000,P > 0. 999]between the observation group and the control group. Conclusion For patients with NSCLC,3D-CRT combined with PC chemotherapy can im-prove the overall response rate,decrease the levels of serum CA125,TIMP-1 and SAA,and improve the im-mune function of patients. The therapeutic effect is remarkable and the safety is good. The therapeutic scheme is suitable for the treatment of NSCLC.

ABSTRACT
Background and purpose:Lung cancer is the leading cause of cancer-related deaths worldwide. Approximately 15%of all histological types consist of small cell lung cancer (SCLC). Chemotherapy is one of the major treatment methods. Though the current front-line standard chemotherapy regimen for SCLC is active in most SCLC cases, however, the disease recurs shortly after the ifrst successful treatment with multi-drug resistance phenotype. Our previously study showed that zinc ifnger protein X-linked (ZFX) was overexpressed in SCLC cells. This study aimed to investigate the expression of ZFX in SCLC tissues, and to clear their possible associations with clinical parameters and provide basis for therapy of SCLC. Methods:A total of 98 surgical specimens of small cell lung cancer were collected. The expression of ZFX was examined by quantiifcational real-time polymerase chain reaction in 78 specimens taken from patients with complete clinical data. Results:The expression of ZFX was signiifcantly increased in extensive stages than in limited stages. The expression of ZFX was associated with tumor stage, the sensitivity of chemotherapy, and survival times (all P0.05). Conclusion: ZFX expression might be associated with the development of SCLC, and may be a potential prognosis predictor.
ABSTRACT
Objective To study the relationship between the expression of nm23- H1 gene product and early distant metastases in nasopharyngeal carcinoma (NPC). Methods The S- P immunohistochemical method was used to detect the expression of nm23- H1 in 95 cases of NPC. Results The positive rate of nm23- H1 was 47.4 % (45/95). The positive rate of nm23- H1 in early distant metastases group (26.7 %) was much lower than those without distant metastases group (60.0 %) (P
