The dry paste yield was utilized as the evaluation criterion, in conjunction with the actual production conditions. Thin layer chromatography was employed to identify Radix Astragali, Lycii Fructus, Herba Dendrobii, and Rhizoma Polygoni Cuspidati. Ethanol served as the solvent for the determination of ethanol-soluble extractives using the cold immersion method.[Results] The preparation process was conducted as follows: the specified quantity of medicinal materials was combined with water for extraction purposes, performed in two separate stages. In each stage, eight times the amount of water was added. The first extraction lasted for 1.5 h, while the second extraction was completed in 1.0 h. The resulting liquid was then concentrated into a thick paste with a relative density ranging from 1.25 to 1.30 at a temperature of 60 ℃. The thin-layer chromatography analysis of Radix Astragali, Lycii Fructus, Herba Dendrobii, and Rhizoma Polygoni Cuspidati demonstrated distinct spots, effective separation, and the absence of interference from negative samples. Additionally, the ethanol-soluble extractives yielded a minimum of 8.0% in terms of dry weight.[Conclusions] The preparation process for Rougan Huaxian ointment is both stable and feasible. Furthermore, the quality standards established for this preparation are unique and reproducible, thereby facilitating effective quality control.展开更多

The law enforcement relies on a monitoring and reporting system to inform the European Commission and the public, for it is the citizens' right to be informed about harmful air quality. With sectoral measures, air quality could be improved in the past 20 years, but some emissions concentrations have stagnated in recent years and emissions temporarily exceed thresholds in nearly half of the Member States. The European Emission Inventory allows the commission to identify the substances, areas, and times of exceedances, and to implement sectoral measures leading to air quality improvements, all of which have to be made available publicly. This manuscript introduces the air quality legislation and reviews the quality of European air for recent years.展开更多

Calculated results of criteria values using popular species sensitivity distribution (SSD) methods were evaluated through data analysis. The comprehensive methodology of emergency water quality standards (EWQSs) was established on the basis of the SSD method of Australia and New Zealand according to the evalu- ation results. The affected fractions of the aquatic organisms were set to be 5 %, 15 %, 30 % and 50 %, corre- sponding to the risk grades of Ⅰ,Ⅱ,Ⅲ and IV, and four-grade EWQSs, respectively. The EWQSs for Cr6+ and Hg2. in the Liao River were derived and the corresponding risk indicators were also proposed. The results showed that the four-grade EWQSs for Cr6+ were 2.85 μg/L, 21.0 μg/L, 161 μg/L and 797 μ/L, respec- tively, and the risk indicators were daphnia (grade Ⅱ ), shrimp (grade Ⅲ), and the bighead fish or tadpole (grade IV). The four-grade EWQSs for Hg2+ were 0.59 μg/L, 2.32 μg/L, 6.25 μg/L and 15.6 μg/L, respective- ly, and the risk indicators were crucian carp or daphnia (grade Ⅱ), shrimp (grade Ⅲ), and worm or crab (grade IV). The results provided valuable information for the risk analysis of sudden ambient water environmen- tal pollution accident.展开更多

The change of accounting standards adopted by Turkey started to be implemented, and this created a number of qualitative and quantitative results. This study examines the impact of change of accounting standards on accounting quality. In order to determine how switching standard reflects accounting quality, first of all, the earnings management, timely loss recognition, and value relevance variables pertaining to accounting quality were listed and the findings were stated after subjecting the obtained data to statistical analyses. Accordingly, by the transition to International Financial Reporting Standards (IFRS), the earnings management practices were observed to decrease as compared with the pre-IFRS period and the timely loss recognition and value-relevance values were observed to increase, which constitute the dimensions of accounting quality. It was also concluded that by the switch from domestic accounting standards to International Accounting Standards (IAS), the quality of accounting in the country was improved and the market became more active than it was before.展开更多

Wedd. [Methods] Microscopic identification and thin layer chromatography were used to identify and determine the moisture, total ash and extract contents. [Results] According to the microscopic results, the stem transection is round and has five longitudinal edges at which the cell wall is obviously thickened. Bristles can be observed. A series of collenchyma cells are arranged closely inside the epidermis. There are several rows of parenchyma cells. The vascular bundles are of different sizes;and the ray part is wide, and at the junction of the ray and the cortex, there are often scattered secretory cells. The center is a broad medulla. The powder is brown. There are many starch grains. The bristles are unicelluar, and have warty protrusions and expanded base. The fibers are bundled, and the cells are large. The epidermal cells are in the shape of an elongated spindle, in a mosaic arrangement, and the cell wall is slightly thickened. From the thin layer identification chromatograms of tested L. bulbifera, it can be seen that spots were observed at the same positions as the control medicinal material, and the durability of the method was good. The extract content should not be less than 12.00% by hot extraction with water as solvent, and not be less than 3.00% by cold extraction with ethanol as solvent. The moisture content should not be more than 16.50%. The total ash content should not be more than 14.00%. The acid-insoluble ash content should not be more than 2.50%. [Conclusions] The microscopic identification results are reliable and can be used as the identification basis of L. bulbifera. The thin layer identification method and the test results can provide a basis for quality control of L. bulbifera.展开更多

[Methods] According to relevant methods specified in Appendix to 2010 Chinese Pharmacopoeia,the water content,total ash,and extracts of Shoushen and Naishoushen were detected,and thin layer chromatography( TLC) was applied to make qualitative identification. Gastrodin was used as the reference substance,extracted with 70% methanol,and then sprayed with ethyl acetate-formic acid-water( 9∶ 1∶ 0. 2) as the developing solvent,and then sprayed with 10% phosphomolybdic acid ethanol solution and heated at 105℃ to clear spot color. UV-Visible spectrophotometry and high performance liquid chromatography( HPLC) were used to analyze the content of polysaccharides and gastrodins in Shoushen and Naishoushen. The chromatographic column was a ZOBB AX eclipse XDB-C_(18)( 4. 6 mm × 250 mm,5 cm) column with the methanol-0. 04% phosphoric acid solution( 8∶92) as the mobile phase,the flow rate of 1. 0mL/min,the detection wavelength of 222 nm,and the column temperature of 30℃.[Results]In the thin-layer chromatography test,spots of the same color appeared at the positions corresponding to the chromatogram of the reference substance. Gastrodin eluted under high pressure reached baseline separation. Gastrodin had a good linearity in the concentration range of 0. 009-0. 09 mg/m L. The regression equation was Y = 586 866 X + 425 821( R^2= 0. 999 6),and the average recovery rate was100. 1%. Precision test,reproducibility test,and stability test conformed to the requirements. The results of extracts of three batches of samples were 26. 13%-42. 58%,water content was 3. 47%-5. 31%,and total ash was 5. 43%-6. 33%. [Conclusions] The quality control method has high reliability,high sensitivity,high specificity,high accuracy,and high stability. The results are expected to provide a scientific basis for the identification,resource utilization,and improvement of quality standard for Shoushen and Naishoushen.展开更多

The EWQSs for Cr6+ and Hg2. in the Liao River were derived and the corresponding risk indicators were also proposed. The results showed that the four-grade EWQSs for Cr6+ were 2.85 μg/L, 21.0 μg/L, 161 μg/L and 797 μ/L, respec- tively, and the risk indicators were daphnia (grade Ⅱ ), shrimp (grade Ⅲ), and the bighead fish or tadpole (grade IV). The four-grade EWQSs for Hg2+ were 0.59 μg/L, 2.32 μg/L, 6.25 μg/L and 15.6 μg/L, respective- ly, and the risk indicators were crucian carp or daphnia (grade Ⅱ), shrimp (grade Ⅲ), and worm or crab (grade IV). The results provided valuable information for the risk analysis of sudden ambient water environmen- tal pollution accident.

文摘With the promulgation of the National Standard for the Teaching Quality of Undergraduate Majors in Ordinary Colleges and Universities, the state has made clear regulations on the standard for the cultivation of Chinese pharmacy talents. Based on their own actual conditions, major colleges and universities have implemented different talent training modes, including talent training modes of running talent classes, "2+1+1", "Chinese Medicine Research Practice Class", employment-oriented professional talent training mode, three-level three-type diversified talent training mode, and talent training mode oriented with adapting to the characteristics of ethnic regions. Various talent training modes have different training objectives, and corresponding training programs are formulated to meet the requirements of the National Standard for the Teaching Quality of Undergraduate Majors in Ordinary Colleges and Universities. In addition, according to the notice on Solidly Promoting Labor Education into the "National Standard for the Teaching Quality of Undergraduate Majors in Ordinary Colleges and Universities" issued by the Department of Higher Education of the Ministry of Education, the introduction of labor education to the teaching of Chinese pharmacy majors will be a trend, and Chinese pharmacy professionals are required to achieve comprehensive and coordinated development of morality, intelligence, physique, beauty, and labor. How to integrate labor education with high quality and high efficiency into the training of Chinese pharmacy professionals is a problem that major universities will think about.

文摘In a developing country, modernization and change of the accounting regime are possible if the standards are in compliance with global ones. The change of accounting standards adopted by Turkey started to be implemented, and this created a number of qualitative and quantitative results. This study examines the impact of change of accounting standards on accounting quality. In order to determine how switching standard reflects accounting quality, first of all, the earnings management, timely loss recognition, and value relevance variables pertaining to accounting quality were listed and the findings were stated after subjecting the obtained data to statistical analyses. Accordingly, by the transition to International Financial Reporting Standards (IFRS), the earnings management practices were observed to decrease as compared with the pre-IFRS period and the timely loss recognition and value-relevance values were observed to increase, which constitute the dimensions of accounting quality. It was also concluded that by the switch from domestic accounting standards to International Accounting Standards (IAS), the quality of accounting in the country was improved and the market became more active than it was before.
文摘Statistics from a recent national sampling survey Indicate that per capita income is rising nationally For example.adjusted per capita family income in]992 for rural residents was more than three times as hugh as that of 1978:similarly,the income for urban residents was more than two times as high for the same period.Although the margin of increase favoured farmers,there still exists a large gap between the Income level of rural compared with urban residents.

文摘[Objectives] This study was conducted to establish the quality control standards for Laportea bulbifera(Sieb. et Zucc.) Wedd. [Methods] Microscopic identification and thin layer chromatography were used to identify and determine the moisture, total ash and extract contents. [Results] According to the microscopic results, the stem transection is round and has five longitudinal edges at which the cell wall is obviously thickened. Bristles can be observed. A series of collenchyma cells are arranged closely inside the epidermis. There are several rows of parenchyma cells. The vascular bundles are of different sizes;and the ray part is wide, and at the junction of the ray and the cortex, there are often scattered secretory cells. The center is a broad medulla. The powder is brown. There are many starch grains. The bristles are unicelluar, and have warty protrusions and expanded base. The fibers are bundled, and the cells are large. The epidermal cells are in the shape of an elongated spindle, in a mosaic arrangement, and the cell wall is slightly thickened. From the thin layer identification chromatograms of tested L. bulbifera, it can be seen that spots were observed at the same positions as the control medicinal material, and the durability of the method was good. The extract content should not be less than 12.00% by hot extraction with water as solvent, and not be less than 3.00% by cold extraction with ethanol as solvent. The moisture content should not be more than 16.50%. The total ash content should not be more than 14.00%. The acid-insoluble ash content should not be more than 2.50%. [Conclusions] The microscopic identification results are reliable and can be used as the identification basis of L. bulbifera. The thin layer identification method and the test results can provide a basis for quality control of L. bulbifera.

文摘[Objectives] To systematically identify and analyze pharmacognostical features of Mongolian medicine Shoushen and Naishoushen( dairy tablets) to provide scientific basis for the establishment and identification of its quality standard. [Methods] According to relevant methods specified in Appendix to 2010 Chinese Pharmacopoeia,the water content,total ash,and extracts of Shoushen and Naishoushen were detected,and thin layer chromatography( TLC) was applied to make qualitative identification. Gastrodin was used as the reference substance,extracted with 70% methanol,and then sprayed with ethyl acetate-formic acid-water( 9∶ 1∶ 0. 2) as the developing solvent,and then sprayed with 10% phosphomolybdic acid ethanol solution and heated at 105℃ to clear spot color. UV-Visible spectrophotometry and high performance liquid chromatography( HPLC) were used to analyze the content of polysaccharides and gastrodins in Shoushen and Naishoushen. The chromatographic column was a ZOBB AX eclipse XDB-C_(18)( 4. 6 mm × 250 mm,5 cm) column with the methanol-0. 04% phosphoric acid solution( 8∶92) as the mobile phase,the flow rate of 1. 0mL/min,the detection wavelength of 222 nm,and the column temperature of 30℃.[Results]In the thin-layer chromatography test,spots of the same color appeared at the positions corresponding to the chromatogram of the reference substance. Gastrodin eluted under high pressure reached baseline separation. Gastrodin had a good linearity in the concentration range of 0. 009-0. 09 mg/m L. The regression equation was Y = 586 866 X + 425 821( R^2= 0. 999 6),and the average recovery rate was100. 1%. Precision test,reproducibility test,and stability test conformed to the requirements. The results of extracts of three batches of samples were 26. 13%-42. 58%,water content was 3. 47%-5. 31%,and total ash was 5. 43%-6. 33%. [Conclusions] The quality control method has high reliability,high sensitivity,high specificity,high accuracy,and high stability. The results are expected to provide a scientific basis for the identification,resource utilization,and improvement of quality standard for Shoushen and Naishoushen.
