Study on Photocatalytic Properties of TiO2 with Special Morphology by Using Natural Template
Get PDFThe TiO₂ photocatalysts with special morphology were synthesized in this paper. The authors used malus micro malus leaves and in docalamus leaves as template, and tetrabutyl titanate (TBT)as Ti source. The special shaped TiO₂ photocatalysts have high photocatalytic activity because of its unique morphology and s tructure. The structure and morphology of TiO₂ were characlerized by XRD and SEM, respectively. The photocatalytic activities were examined by the photodegradation of methylene blue (MB) under ultraviolet light (λ=365nm) iradiation. The results indicated that the TiO2 photocatalyst,using indocalamus leaves as templates, exhibited better adsorption and photocatalytic performance in degrading MB than using malus micro malus leaves, when the amount of nitric acid was 20 mL and following heat treatment at 600 ℃
The Influence of Polygonatum King ilium on the Activity of Calcium-Regulating Enzymes and Calcium Ion Concentration in SH-SY5Y Cells Damaged by Aβ25-35 In Vitro
Get PDFObjective To explore the effects of Polygonatum King ilium and Earthworm Formula (RPEWM) on the activity of calcium-regulating enzymes and free calcium ion (Ca2+) concentration in SH-SY5Y cells with Aβ damage in vitro. Methods SH-SY5Y cells were induced to differentiate with retinoic acid, then damaged by Aβ to mimic Alzheimer\u27s disease (AD) injury. RPEWM extract was added during the AD injury to protect the cells, and its effects on cell proliferation, apoptosis, and the activity of cellular Ca2+-ATPase､Ca2+-Mg2+- ATPase ,as well as free calcium ion concentration were observed. Results RPEWM extract significantly protected cells from AD injury, resisted apoptosis, and promoted cell proliferation; it increased the activity of intracellular Ca2+-ATPase､Ca2+-Mg2+- ATPase, reduced Ca2+ concentration, and showed a dose-dependent relationship. Conclusion RPEWM has a good protective effect on differentiated SH-SY5Y cells with Aβ25-35damage and has a certain therapeutic effect on AD
Therapeutic effects investigation of physical therapy and pharmacotherapy in the treatment of persistent allergic rhinitis
Get PDFTo investigate the therapeutic effects of physical therapy and pharmacotherapy in the treatment of persistent allergic rhinitis. Methods:192 patients were randomly divided into 3groups, A group 72 cases, B group 70 cases. A and B group were treated with focused ultrasound and radiofrequency ablation respectively under the endoscope and using spraying Mometasone Furoate Nasal Spray for 1month after the operation. Patients of C group use the Mometasone Furoate Nasal Spray and Cetirizine Hydro- chloride Tablets for 1 month. Follow up for 6 months after treatment and evaluate the curative effect with soring method. Results: Total effectiveness was as fllowed:1st months: A group 97.2%, B group 97.1%C group 96.0%;6 months: A group 90.3%, B group 87.1%, C group 64.0%. The curative effect score of three group after the treatment for 1month have no significant difference (P>0.05). Comparing the efficiency of patients in three groups after treatment for 6 months, there was significant difference of stat is tactically significance. The efficiency of A and B group were higher than group C(P<0.05).A group was better than B group with the score of sneezing after the treatment ,the difference was significant(P<0.05).But B group was better than A group with the score of nasal congestion ,the difference was significant(P<0.05).Conclusion: The curative effect of treatment with two physical therapy methods combined with mometasone furoate for persistent allergic rhinitis, the former is better than the latter for sneezing ,but the improvement of nasal congestion is less than the latter. Long-erm therapeutic effect of drug with AR is less than physical therapy in combination with drug. The treatment with focused ultrasound combined with mometasone furoate for persistent AR is worth promoting, especially suitable for medium and severe persistent AR patients
Research on the modification technology of beta molecular sieve
Get PDFThe influence of temperature and time of the acid washing and hydrothermal treatment on Beta zeolite properties was examined in detail, the results revealed that acid washing at 2h and 80℃and 2h hydrothermal treatment at 650℃are the best modification operating conditions. The different SiO2/Al2O3ratio of Beta zeolite are systematically modified using optimized modification operating conditions. Beta zeolite modified from higher SiO2/Al2O3ratio of the starting Beta also has higher SiO2/Al2O3 ratio. Crystallinity of starting Beta zeolite has less effect on the modified Beta zeolite. As the SiO2/Al2O3 ratio of starting Beta increased, total acid amount of modified Beta decreased. When the SiO2/Al2O3 ratio of starting Beta is bigger, the surface area and pore volume is higher
Study on the correlation between ultrasonic signs and molecular biological expression in breast cancer
Get PDFObjective: To explore the correlation between ultrasonic signs and molecular biological expression in breast cancer, in order to improve the diagnostic level of ultrasound for breast cancer and provide reliable imaging information for the treatment and prognosis assessment of breast cancer. Methods: A total of 50 patients with breast cancer confirmed by surgical pathology were randomly selected and underwent high-frequency breast ultrasound examination, focusing on observing the shape, edge, posterior echo, microcalcification, internal blood flow, and axillary lymph nodes of the mass; immunohistochemistry was used to detect the expression of ER, PR, and CerbB-2 genes, and their relationship with ultrasound performance was analyzed. Results: ① The detection rate of microcalcification in breast cancer <2cm was the highest, followed by spiculated edge; the detection rate of irregular shape was higher in tumors >2cm. ② The positive rate of ER and PR in patients with a tumor aspect ratio >1 was 77.8% and 61.1%, respectively, which was higher than those with an aspect ratio ≤1 (P<0.05); ③ The positive rate of ER and PR in patients with spiculated edge signs was 65.5% and 55.2%, respectively, which was higher than those without spiculated edge (P<0.05); ④ The positive rate of ER and PR in patients with peripheral high echo dizzy was 73.3% and 60.0%, respectively, both higher than those without high echo dizzy (P<0.05); ⑤ The positive rate of PR in patients with anechoic area was 22.2%, lower than those without anechoic area (P<0.05); ⑥ The positive rate of CerbB-2 in patients with microcalcification was 83.3%, higher than those without microcalcification (P<0.05). Conclusion: There is a certain relationship between the ultrasound performance of breast cancer and the expression of molecular biological indicators, and the biological characteristics of the tumor affect the ultrasound performance of breast cancer. Ultrasound examination can provide imaging basis for the prognosis assessment and clinical treatment selection of breast cancer

Adolescent core literacy cultivation and institutional framework development
Get PDFThe core literacy of adolescents is the starting point and the ultimate goal of education, serving as a touchstone for assessing the quality of talent and the level of education, and also as a guiding compass for the development, reform, and construction of education. Countries around the world attach great importance to the core literacy of adolescents, showing characteristics of macro cognitive consistency, diversified element selection, and specific operational aspects. To achieve the goals of core literacy for our country\u27s adolescents, it is necessary to influence the attitudes, concepts, behavioral habits, and interactive relationships of participants and stakeholders in the educational process, including the government, schools, enterprises, families, and students. It is also necessary to improve the literacy monitoring mechanism, reform the educational examination system, transform the educational evaluation methods, improve the employer\u27s employment orientation, optimize the social education environment, innovate the educational supply mode, and strive to build a modern educational system to create a good atmosphere for enhancing the core literacy of adolescents
