1. Association between variable number of tandem repeat polymorphism of thymidylate synthase gene and efficacy of pemetrexed in the treatment of advanced non-small cell lung cancer
Tumor 2012;32(7):539-545
Objective: To investigate the association between variable number of tandem repeat (VNTR) polymorphism in 5'-untranslation region (5'-UTR) of thymidylate synthase (TS ) gene and the efficacy of pemetrexed-based treatment in non-small cell lung cancer (NSCLC). Methods: Peripheral blood samples were collected from 90 patients with advanced NSCLC and the genomic DNAs were extracted from these blood samples. The VNTR polymorphism in 5'-UTR of TS gene was detected by fluorescent labeled PCR and multiplex short tandem repeat polymerase chain reaction in combination with capillary electrophoresis. Results: The homozygosis (3R/3R and 2R/2R) and heterozygosis (2R/3R and 3R/4R) of VNTR polymorphism in 5'-UTR of TS gene were not associated with the efficacy of pemetrexed. The progression-free survivals, disease control rates and the objective response rates in patients harboring homozygosis (3R/3R and 2R/2R) and heterozygosis (2R/3R and 3R/4R) were 112 and 94 d (P = 0.549), 64.3% and 67.6% (P = 0.745), and 12.5% and 8.8% (P = 0.591), respectively. The patients harboring 2R alleles had similar clinical outcomes as compared with those harboring 3R alleles (progression-free survival: P = 0.518; disease control rate: P = 0.631; objective response rate: P = 0.541). Conclusion: TS gene VNTR polymorphism may not be associated with clinical outcomes of advanced NSCLC treated with pemetrexed. Copyright © 2012 by TUMOR.
2.Dual role of dendritic cells in the pathological mechanism of atherosclerosis
International Journal of Surgery 2013;40(12):831-834
Atherosclerosis is a chronic inflammatory immune disease,which is one of the causes of human lower limb disability.Dendritic cells are the most powerful professional antigen presenting cell in immune system,and dendritic cells have the dual role of immunogenicity and tolerability.As a professional antigen presenting cell,the immunogenicity of dendritic cells present self abnormal antigen and course immune system disorder,which may be one role of dendritic cells participate in atherosclerosis.However,the tolerability of dendritic cells can course the generation of immune tolerance,which makes dendritic cells exert a regulatory role in atherosclerosis.This paper makes an introduction about how dendritic cells are involved and play a regulatory role in the pathogenesis of atherosderosis.
3.Qualitative research of post-traumatic growth in caregivers of dementia patients
Modern Clinical Nursing 2015;(8):42-45,46
Objective To analyze post-traumatic growth of Chinese caregivers of dementia patients and to explore the caregivers′positive and potential energy, in order to formulate more perfect nursing intervention measures. Method Useing phenomenological method of qualitative research in selecting 6 dementia caregivers in-depth interviews to understand possible posttraumatic growth. Result Five major themes were found: changes in individual cognitive, changes in relations with others, promote their children′s education, reflections and concerns on status of pension-related changes in philosophy of life. Conclusions Dementia caregivers also have the positive performance of posttraumatic growth, in addition to the negative experience. Clinical nurses should actively explore the potential and power from the growth perspective. This is conducive to the caregivers with more health caring for life, so as to improve the quality of care, and ultimately improve the quality of life.

Objective To investigate the clinical significance of detection of growth differentiation factor 3(GDF3), prostate specific antigen(PSA) combined with mucin 1(MUC1)for diagnosis of breast cancer.Methods50 cases of breast cancer were selected as the breast cancer group, 50 cases of benign breast disease were selected as the benign breast disease group, and 50 healthy people were selected as the normal group.GDF3, PSA, MUC1 and tumor markets carbohydrate antigen(CA)15-3,CA125,carcinoembryonic antigen(CEA) were detected, and sensitivity, specificity and accuracy were analyzed.ResultsCompared with benign breast disease group and normal group, GDF3, PSA and MUC1 in breast cancer group were higher(P<0.05), CA15-3, CA125 and CEA were higher(P<0.05).The sensitivity, specificity and accuracy of PSA+MUC1 were higher than other group(P<0.05),the sensitivity, specificity and accuracy of combined detection of GDF3, PSA and MUC1 were higher(P<0.05).ConclusionDetection of GDF3 combined with MUC1 and PSA for early diagnosis of breast cancer has more diagnostic significance.

OBJECTIVE:To analyze the chemical constituents of the essential oil extracted from Mosla chinensis seeds. METHODS: The essential oil was extracted from Mosla chinensis seeds by steam distillation method and identified by GC-MS, and its relative content was determined using normalization method. RESULTS: A total of 20 chromatographic peaks were detected and 17 chemical compounds were identified, which made up 99.06% of the total essential oil content. The major chemical constituents were carvacrol(57.01%), thymol(30.72%), thymol acetate(2.56%), carvacrol acetate(2.14%) and ?-caryophyllene(1.62%). CONCLUSION: The results in our study provides scientific basis for further exploitation and utilization of Mosla chinensis and serves as reference for establishing quality standard of Mosla chinensis herbal medicine.

BACKGROUND:Polyester fabric as a common clinical consumable item is characterized by simple drawing, low cost, and high toughness and ductility, and can serve as a good repair material. OBJECTIVE:To investigate the clinical efficacy of polyester fabrics used for huge chest wal repair. METHODS: Totaly 46 patients with chest wal tumors, aged 39-73 years, including 29 males and 17 females. These patients were randomly and equaly divided into observation group and control group. After the removal of chest wal tumors, patients in the observation group underwent polyester fabric repair of huge chest wal defects, and those in the control group were treated with autologous pedicle flap for repair of huge chest wal defects. The clinical efficacy and patient satisfaction were recorded in the two groups. RESULTS AND CONCLUSION: After treatment, al the patients could feel up to their daily work, and there were no death and serious complications. Only two cases developed postoperative local effusion, and then recovered after wound drainage. Thoracic appearance was good in al patients, and the patients did not feel discomfort at the reconstruction site during breathing and movement. At the end of 6-24 months of folow-up, X-ray review showed good reconstruction of the thorax, and there were no loose transplants, foreign body rejection, chest wal deformity, recurrence and serious complications. Clinical efficacy and patient satisfaction were better in theobservation group than the control group (P < 0.05). These results show that polyester fabrics for the repair of huge chest wal defects are effectively, safe and reliable.
