RESUMO

OBJECTIVE To evaluate the comprehensive quality of Houttuynia cordata from different producing areas. METHODS Using total flavonoids, water-soluble extract, moisture, total ash and acid-insoluble ash as indicators, the entropy weight method was used to objectively weigh each indicator, and the relative correlation degree (r)i calculated by grey correlation method was used as a measure to comprehensively evaluate the quality of H. cordata. RESULTS The weights of total flavonoids, total ash, moisture, acid-insoluble ash, and water-soluble extract were 0.295 5, 0.227 3, 0.188 7, 0.145 1, and 0.143 4, respectively. The weights of total flavonoids and total ash were relatively large. The ri of 30 batches of H. cordata ranged from 0.233 2 to 0.673 9; the average ri of samples from Quanzhou County and Ziyuan County of Guangxi Zhuang Autonomous Region were the highest, which were 0.638 3 and 0.598 7, respectively, followed by samples from Lingchuan County of Guangxi Zhuang Autonomous Region (0.556 1) and Jianshui County of Yunnan Province (0.452 8). The quality of medicinal materials produced in the above producing areas was generally good and stable. CONCLUSIONS Entropy weight method combined with the grey correlation method can be used to comprehensively evaluate the quality of H. cordata. The overall quality of H. cordata produced in Quanzhou County of Guangxi Zhuang Autonomous Region is the best.

RESUMO

【Objective】 To investigate the resource allocation status of blood testing laboratories in 14 blood stations in Gansu Province, explore the impact of differences in basic conditions on the comprehensive testing ability of laboratories, so as to promote the homogenization and standardization of blood screening capacity in blood stations in Gansu and improve blood safety and effectivenes. 【Methods】 An evaluation index system of laboratory resource allocation was constructed and a question-naire was designed. The data of human resources, infrastructure and key equipment of 14 blood stations were collected. The entropy weight -TOPSIS method was used to evaluate and rank the resource allocation of 14 blood stations. 【Results】 In the comprehensive evaluation of blood testing laboratory resource allocation in 14 blood stations in Gansu, the top three were laboratories A, B and I, and the last three were laboratories G, M and J. On the whole, the main issue was unreasonable structure of human resources: most laboratories had unreasonable age structure; except for Laboratory A, there was no personnel with bachelor's degree or above in laboratories; most laboratories had not established a team with intermediate professional titles. In terms of infrastructure, the size of seven laboratories could not meet the needs of modern laboratory testing, and all eight blood stations had no spare nucleic acid laboratories nor a mutual spare laboratory with other blood stations As for the key equipment, 5 laboratories had no automatic blood grouping diagnostic instrument, 5 laboratories only had one set of enzyme immunoassay detection system, 3 laboratories had no spare equipment for the key equipment, which means if the equipment failure could not be repaired in time, the release of results would be affected. 【Conclusion】 There were significant differences in human resources, infrastructure and key equipment of blood testing laboratories in 14 blood stations in Gansu, which had a great impact on laboratory testing capacity and subsequent development. It is suggested that governments at all levels and health administrative departments optimize the input of laboratory resource allocation according to the blood collection volume of blood stations to gradually narrow the differences in resource distribution between different regions, improve the degree of laboratory automation and optimize the personnel structure, so as to build high-quality and efficient blood testing laboratories and ensure the safety of clinical blood use.

RESUMO

OBJECTIVE To optimize the processing technology of honey bran-fried Atractylodis Rhizoma, and to compare the anti-gastric ulcer effect before and after processing. METHODS Combing with entropy-weight and technique for order preference by similarity to ideal solution model, L(9 34) orthogonal experiment design was adopted to optimize the processing technology of honey bran-fried Atractylodis Rhizoma using the comprehensive score of the contents of atractylone, β-cineole, atractylenolide Ⅲ and atractylodine as evaluation index, using the ratio of excipients to medicine, frying temperature and frying time as factors. The validation tests were conducted. The gastric ulcer model of mice was induced by intragastrical administration of anhydrous ethanol; using Compound aluminum hydroxide tablet as positive control, anti-gastric ulcer effect of Atractylodis Rhizoma was compared with that of honey bran-fried Atractylodis Rhizoma using the contents of serum inflammatory factors [interleukin-2 (IL-2), IL-6, tumor necrosis factor-α (TNF-α)], ulcer index and inhibitory rate of gastric ulcer as evaluation indexes. RESULTS The optimal processing technology of honey bran-fried Atractylodis Rhizoma was as follows:ratio of adjuvant and medicinal materials of 3∶10 (g/g), frying temperature at 140 ℃ and frying time of 4 min. Results of 3 validation tests showed that the contents of 4 components (including atractylone), in honey bran-fried Atractylodis Rhizoma processed by the optimal technology kept stable (RSDs were 3.47%-5.80%, n=3); the comprehensive scores were 95.53%-95.89% (RSD=0.21%, n=3). Atractylodis Rhizoma and honey bran-fried Atractylodis Rhizoma could increase the serum content of IL-2 in mice, but reduce serum contents of IL-6 and TNF-α to varying degrees; honey bran-fried Atractylodis Rhizoma could significantly decrease its ulcer indexes (P<0.05 or P< 0.01); the improvement effect of honey bran-fried Atractylodis Rhizoma on the above indicators was generally better than that of the same dosage of Atractylodis Rhizoma (P<0.05 or P< 0.01). The inhibitory rates of low-dose, medium-dose and high-dose Atractylodis Rhizoma and honey bran-fried Atractylodis Rhizoma to gastric ulcer in mice were 9.18%, 19.30%, 30.70%, and 50.32%, 61.39%, 53.16%, respectively. CONCLUSIONS The optimal processing technology of honey bran-fried Atractylodis Rhizoma is stable and feasible, and the anti-gastric ulcer effect of Atractylodis Rhizoma has been enhanced after being fried with honey bran.

RESUMO

Based on the concept of quality by design(QbD), the Box-Behnken design-response surface methodology combined with standard relation(SR) and analytic hierarchy process(AHP)-entropy weight method(EWM) was applied to optimize the extraction process of the classic prescription Yihuang Decoction. The content of geniposidic acid, phellodendrine hydrochloride, and berberine hydrochloride in Yihuang Decoction, the extract yield, and fingerprint similarity were used as the critical quality attributes(CQAs) of the extraction process. The extraction time, water addition, and extraction times were used as the critical process parameters(CPPs). After determining the levels of each factor and level through single-factor experiments, response surface experiments were designed according to the Box-Behnken principle, and the experimental results were analyzed. The SR between each sample and the reference sample under various evaluation indicators of different extraction parameters was calculated. The weights of the five evaluation indicators were determined using AHP-EWM, followed by comprehensive evaluation. A function model between CPPs and CQAs characterized by comprehensive scores was established to predict the optimal extraction process parameters. In the final comprehensive weight coefficients, the yield rate accounted for 43.1%, and the content of berberine hydrochloride, phellodendrine hydrochloride, and geniposidic acid accounted for 35.1%, 6.3%, and 15.5%, respectively. After comprehensive score analysis with SR, the established second-order polynomial model was statistically significant(P<0.01, and the lack of fit was not significant). The predicted optimal extraction conditions for Yihuang Decoction were determined as follows: 8-fold volume of water, extraction time of 1.5 h, and extraction once. The mean comprehensive score of the validation experiment was 85.77, with an RSD of 0.99%, and it met the quality control stan-dards for the reference sample of Yihuang Decoction. The results indicate that the optimized extraction process for Yihuang Decoction is stable and reliable, and the water extract is close in quality attributes to the reference sample. This can serve as a foundation for the research and development of granules in the future. Box-Behnken design-response surface methodology combined with SR and AHP-EWM can provide references for the modern extraction process research of other classic prescriptions.

RESUMO

Analytic hierarchy process(AHP)-entropy weight method(EWM) and network pharmacology were employed to identify the potential quality markers(Q-markers) of Gei Herba. According to the new concept of Q-markers in traditional Chinese medicine(TCM), the AHP-EWM was applied to quantitatively identify the Q-markers of Gei Herba. The AHP was used for the weight analysis of primary indicators(factor layer), and the EWM for the analysis of literature and experimental data of secondary indicators(control layer). In addition, network pharmacology was employed to build the "component-target-disease-efficacy" network for Gei Herba, and the components showing strong associations with the Qi-replenishing, spleen-invigorating, blood-tonifying, Yin-nourishing, lung-moistening, and phlegm-resolving effects of Gei Herba were screened out. According to the results of AHP-EWM and network pharmacology, four components, i.e., ellagic acid, gallic acid, gemin G, and gemin C, were finally identified as potential Q-markers of Gei Herba. In this study, the AHP-EWM and network pharmacology were employed to screen the Q-markers of Gei Herba, which provided ideas for the quantitative evaluation and identification of Q-markers of TCM.

RESUMO

To study the effects of different drying methods on the quality of male flowers of Eucommia ulmoides(MFOEU), we treated fresh MFOEU samples with drying in the shade(DS), vacuum freeze drying(VFD), high-or low-temperature hot air drying(HTHAD, LTHAD), microwave drying(MD), and vacuum drying(VD), respectively. The color, total flavonoid content, total polysaccharide content, and main active components such as geniposide, geniposidic acid, rutin, chlorogenic acid, galuteolin, pinoresinol diglucoside, and aucubin in MFOEU were taken as the evaluation indicators. The quality of MFOEU was comprehensively evaluated by entropy weight method combined with color index method, partial least squares discriminant analysis and content clustering heat map. The experimental results showed that VFD and DS basically kept the original color of MFOEU. The MFOEU treated with MD had higher content of total polysaccharides, phenylpropanoids, lignans, and iridoids. The MFOEU treated with LTHAD had higher content of total flavonoids and that treated with VD had lower content of active components. According to the results of comprehensive evaluation, the quality of MFOEU dried with different methods followed the order of MD>HTHAD>VFD>LTHAD>DS>VD. Considering the color of MFOEU, the suitable drying methods were DS and VFD. Considering the color, active components, and economic benefits of MFOEU, MD was the suitable drying method. The results of this study are of a reference value for the determination of suitable methods for MFOEU processing in the producing areas.

RESUMO

The potential quality markers(Q-markers) of Polygoni Perfoliati Herba were studied based on analytic hierarchy process(AHP)-entropy weight method(EWM), network pharmacology, and spectrum-effect relationship analysis. The AHP-EWM was used for quantitative identification of the Q-markers. To be specific, AHP was applied for the weight analysis of the validity, testability, and specificity of the first-level indexes, and EWM for the analysis of the second-level indexes supported by literature and experimental data. Based on literature and network pharmacology, the validity analysis was to study the component-target-disease-efficacy network, and select the components with the strongest correlation with the efficacy of clearing heat and removing toxin, diuresis and alleviating edema, and relieving cough. For the testability analysis, the high performance liquid chromatography(HPLC) and literature research were used to determine the 10 components in Polygoni Perfoliati Herba, and the fingerprints of Polygoni Perfoliati Herba were established at the same time. The specificity analysis was based on the statistics of the number of plants in which the components existed. Thereby, the 11 compounds: quercetin, oleanolic acid, ellagic acid, gallic acid, kaempferol, rutin, esculetin, quercetin-3-O-glucuronide, ursolic acid, protocatechuic acid, and ferulic acid, were identified as potential Q-markers. The 11 compounds were identified to have high anti-inflammatory activity, indicating that the 11 Q-markers may be the functional material basis. The result in this study is expected to serve as a reference for the quality control of Polygoni Perfoliati Herba.

RESUMO

@#To promote the construction of first-class disciplines of "Double First-Class" universities in China, the construction of a comprehensive evaluation system was explored, so as to provide suggestions for the development of these disciplines.Essential Science Indicators (ESI), InCites and Derwent Innovation Index databases, together with range transformation method and entropy weight method, were employed to analyze the data in the field of pharmacology and toxicology from some universities; the construction approaches and index performance of the system were studied. The score performances of the sample universities in the index system are different from their ESI rankings, suggesting that the system has certain practical value.ESI rankings cannot fully reflect the development levels of disciplines, while the multi-dimensional index evaluation system can overcome this shortcoming to a certain extent.This paper establishes an evaluation system with published papers and granted patents as the main evaluation objects, covering as many multi-angle indicators of scientific research output as possible, and trying to overcome the disadvantages due to lack of information in a single or few index systems.It is suggested that universities should formulate their discipline development plans from the perspectives of publishing high-quality original research results, leading or widely participating in scientific research cooperation, strengthening university-enterprise cooperation, promoting the application of research results, promoting open science and encouraging open access.

RESUMO

OBJECTIVE To identify and evaluate the risk factors in the operation process of the vaccine supply chain ,clarify the importance of each process risk in the overall risk of the vaccine supply chain ,and provide reference for stakeholders in the vaccine supply chain to formulate risk management and control strategies. METHODS In the supply chain operation reference model,the risk factors existing in the operation of vaccine supply chain were identified ,and the vaccine supply chain risk evaluation index system was constructed. The best-worst method and entropy weight method were used to determine the subjective and objective weight of the index ,and the Lagrange multiplier method was used to solve the optimal combination weight value of the index. RESULTS & CONCLUSIONS A vaccine supply chain risk evaluation index system with 18 indexes was established. Only 67% of the indexes reflected 85% of the vaccine supply chain risk information. The construction of the system was reasonable. The results showed that the risk weight of production process was 0.607,which accounts for the highest weight in the overall risk of vaccine supply chain ,followed by procurement (0.234),distribution(0.102),planning(0.053)and return (0.004) process risk . When managing and controlling risks ,enterprises should attach great importance to the risk factors in vaccine production;at the same time ,enterprises should also focus on other risks such as unqualified materials for products ,mixed use of materials and so on.

RESUMO

The quality markers (Q-markers) of traditional Chinese medicine (TCM) have become a topic of interest in TCM research in recent years. Nonetheless, there is still no consensus on how to scientifically characterize TCM Q-markers. Our study establishes an identification method for TCM Q-markers based on the analytical hierarchy process (AHP) and the entropy weight comprehensive method. By constructing an evaluation system encompassing the target layer, the factor layer and the control layer, AHP can be used to analyze the weight of three core TCM quality attributes, including effectiveness, testability and specificity. Following that, the entropy weight method is employed to analyze the specific indicators for each attribute based on the literature and experimental data. Finally, the comprehensive weight of each index is obtained by combining the two weights, and the comprehensive weight and the specific value of each component is multiplied and summed to obtain the integrated score ranking, and thereby identify the TCM Q-markers. Taking Shaoyao Gancao decoction as an example, the analysis revealed that the top 8 components are as follows: paeoniflorin > quercetin > albiflorin > glycyrrhizic acid > naringenin > liquiritin > oxypaeoniflorin > benzoylpaeoniflorin, and can be identified as Q-markers of Shaoyao Gancao decoction. This study not only provides support for the establishment of quality standards and process quality control of TCM formulae, but also provides innovative ideas and methods for quantitative evaluation and accurate identification of TCM Q-markers.
