Objective To explore the effect of health education on improving awareness of preven-tion of upper respiratory tract infection of parents of leukemia children. Methods 25 parents were ran-domly chosen, and comprehensive health education interventions were provided, including lectures, advisory guidance and brochures. The awareness of prevention of upper respiratory tract infection of parents was e-valuated before and after health education,and the results underwent χ<'2> test. Results After health educa-tion, the awareness of prevention of upper respiratory tract infection of parents significantly improved com-pared with that before. Conclusions Health education can improve awareness of prevention of upper res-piratory tract infection of parents and decrease the incidence of upper respiratory tract infections.

Objective To evaluate the expression and activity of GFP/TRAIL gene activated by the hTERT promoter on colon cancer cell line DLD-1. MethodsGFP/TRAIL gene activated by the hTERT promoter was transfected into DLD-1 with adenoviral vector,expression and apoptosis inducing ability of GFP/TRAIL protein was determined by fluorescence-activated cell sorting (FACS). [WT5”HZ]ResultsThe expression of GFP gene is 41.63% and 54.07% with either hTERT promoter or CMV promoter in DLD1 cells;GFP/TRAIL gene was able to inhibit cell growth(93.50%) and induce apoptosis(56.97%) of DLD-1 ,there was significant difference between Ad/hTERT-gTRAIL and the other two control groups (PBS and Ad/hTERT-LacZ)( P

AIM: To explore the influence of Chrysanthemum morifolium Ramat on TNF-related apoptosis inducing ligand (TRAIL)-mediated apoptosis in human colon cancer cell line DLD-1 and its possible mechanism. METHODS: Adenovirus-mediated TRAIL gene AD/hTERT-gTRAIL was applied either alone or by combination with Chrysanthemum morifolium Ramat in human colon DLD-1 cell line. Cell growth and apoptosis were measured by inverted microscope, MTT method and flow cytometry. The expression of TRAIL mRNA, TRAIL-Rs mRNA and TRAIL protein expression after exposure to Chrysanthemum morifolium Ramat were measured by semi-quantitive RT-PCR and FACS, respectively. RESULTS: The suppression percentages and apoptotic rate of DLD-1 by Ad/hTERT-gTRAIL alone were 31.4% and 13.5%, respectively. Combination of TRAIL gene transfection with Chrysanthemum morifolium Ramat, the suppression and the apoptosis rate raised to 93.1% and 45.4%, respectively (P

Objective:To investigate the changes and clinical significance of serum matrix metalloproteinase-9 (MMP-9), squamous cell carcinoma antigen (SCC), cytokeratin 19 fragment (CYFRA21-1), carcinoembryonic antigen (CEA) and neuron-specific enolase (NSE) in peripheral lung cancer.Methods:Sixty-eight patients with peripheral lung cancer who received treatment in Luqiao Hospital of Taizhou Enze Medical Center (Group) between January 2017 and January 2020 were included in the observation group. Sixty-five patients with benign lung diseases who concurrently received treatment in the same hospital were included in the observation group 1, and another 65 healthy participants who concurrently received physical examination were included in the control group. Serum levels of MMP-9, CYFRA21-1, SCC, NSE and CEA were compared among the three groups. The sensitivity and specificity of using these indicators alone and in combination in the diagnosis of peripheral lung cancer were compared.Results:Serum levels of MMP-9, CYFRA21-1, SCC, NSE and CEA in the observation group (14.98 ± 2.10) ng/mL, (17.13 ± 2.71) ng/mL, (1.98 ± 0.41) μg/mL, (24.13 ± 2.10) ng/mL and (17.10 ± 2.10) ng/mL, respectively, which were significantly higher than those in the observation group 1 [(9.12 ± 1.41) ng/mL, (10.12 ± 1.58) ng/mL, (1.37 ± 0.31) μg/mL, (16.31 ± 1.78) ng/mL, (12.13 ± 1.79) ng/mL] and control group [(5.10 1 ± 0.68) ng/mL, (6.02 ± 0.94) ng/mL, (0.71 ± 0.11) μg/mL, (11.10 ± 1.02) ng/mL, (8.13 ± 1.02) ng/mL] ( F1 = 932.781, F2 = 737.100, F3 = 368.591, F4 = 989.851, F5 = 462.291, all P < 0.05). Serum levels of MMP-9, CYFRA21-1, SCC, NSE and CEA in patients with stage I-II peripheral lung cancer were (11.12 ± 2.10) ng/mL, (9.12 ± 1.85) ng/mL, (1.52 ± 0.21) μg/mL, (18.12 ± 3.02) ng/mL, (7.52 ± 1.02) ng/mL, respectively, which were significantly lower than those in patients with stage III-IV peripheral lung cancer [(15. 89 ± 2.18) ng/mL, (21.56 ± 2.11) ng/mL, (2.04 ± 0.31) μg/mL, (28.15 ± 2.62) ng/mL, (15.12 ± 1.55) ng/mL, t1 = 9.013, t2 = 25.146, t3 = 7.714, t4 = 14.586, t5 = 22.705, all P < 0.05]. The sensitivity (83.33%) and specificity (86.67%) of combined detection of all indicators were significantly higher than those of single detection of MMP-9 (50.00%, 59.68%), CEA (50.00%, 61.29%), CYFRA21-1 (66.67%, 58.06%), SCC (50.00%, 54.84%) or NSE (66.67%, 58.06%) (all P < 0.05). Conclusion:Serum levels of MMP-9, CYFRA21-1, SCC, NSE and CEA in patients with peripheral lung cancer are significantly increased, which has an important value in the diagnosis of peripheral lung cancer. The combined detection of the above indicators can increase the diagnostic accuracy of peripheral lung cancer in the clinic.
