Evaluation of secretory activity in carp pancreatocytes (Cyprinus carpio L. ) when using lactobacillus-based chelate and probiotic supplemental feed complexes / Avaliação da atividade secretora em pancreatócitos de carpa (Cyprinus carpio L. ) ao usar quelato à base de lactobacilos e complexos suplementares de alimentação probiótica

The experimental research was carried out on the juvenile carp (Cyprinus carpio L.). The impact from supplemental feeds consisting of variable concentrations of chelate compounds, biogenic trace elements and probiotic lactobacillus-based product Bacillus subtilis VKPM B-2335 was evaluated. Optical and qualitative parameters of the lactobacillus base were studied in order to identify the major group of substances potentially able to influence the end result. The purpose of this research was to identify changes in the structure of the zymogen granules and their dimensions at which supplemental feeds produce a stimulating effect on the synthesis of zymogens in exogenous cells of the secretory part of pancreas. At the outcome of the study, for the first time, it was possible to prove that the integrated action of chelates and lactobacillus-based probiotics complemented each other. Metal chelate compounds contributed to enlargement of the zymogen granules, if compared to the control values. The bacterial products accelerated production of the zymogen granules in acinar cells diffusely located in carp hepatopancreas.

Analysis of Formulation and Characteristics of Provincial Standards for Traditional Chinese Medicine Dispensing Granules / 中国实验方剂学杂志

In order to standardize the quality control of traditional Chinese medicine（TCM） dispensing granules， the Chinese Pharmacopoeia Commission has promulgated and implemented 200 national drug standards for TCM dispensing granules， but there are still varieties of TCM dispensing granules without unified standards. Many provinces have actively invested in the formulation of provincial standards for TCM dispensing granules to make up for the gaps in standards for varieties of traditional Chinese medicine dispensing granules other than the national standards. By the end of July 2022， 29 provincial-level administrative regions have successively promulgated and implemented a total of 5 602 provincial standards for TCM dispensing granules， involving more than 400 varieties. In order to better understand the formulation and characteristics of provincial standards， this study took 105 provincial standards that have been promulgated and implemented in Henan province as an example， and comprehensively analyzed the formulation and characteristics through quality control indicators such as dry extract rate of raw materials， contents of index components and their transfer rates， specifications and so on. The formulation and characteristics of the same TCM dispensing granules in the provincial standards of different provinces were further analyzed， in order to provide reference for the formulation of provincial standards of TCM dispensing granules and the implementation of national standards.

Exploration of “six-step”management mode to reduce the utilization rate of intravenous infusion in inpatients / 中国药房

OBJECTIVE To explore and establish a long-term mechanism for rational control of intravenous fluids in hospitals. METHODS On the basis of the establishment of rules and regulations， through the exploration and implementation of the core technical strategy of “six-step method”， a new mode of intravenous infusion control was established. The contents of the “six-step method” were as follows： the first step was to sort out the diseases that did not require intravenous infusion； the second step was to sort out the alternative drugs/dosage forms； the third step was to sort out the alternative routes of infusion； the fourth step was to develop drug specifications； the fifth step was to explore the personalized medication needs of clinical departments； the sixth step was to develop a department-specific integrated infusion regimen. The utilization rate of intravenous fluids in inpatients and the average daily amount of intravenous fluids per bed in inpatients were used as the main indicators to evaluate the control effect. RESULTS The comparison of the average values of three months before and after the implementation of the “six-step” management mode in the department of thoracic surgery of our hospital showed that after management and control， the average utilization rate of intravenous fluids in inpatients decreased by 1.74%， the average daily use of intravenous fluids in inpatients per bed decreased by 0.30 bags/bottle， and the per capita use of infusion drugs under key control gradually decreased. CONCLUSIONS The “six-step” management mode can reduce the utilization rate of intravenous fluids in inpatients， and this management mode is practical and feasible.

Discussion on the use of occupational contraindication cardiovascular disease in Technical Specifications for Occupational Health Surveillance (GBZ 188-2014) / 中华劳动卫生职业病杂志

Technical Specifications for Occupational Health Surveillance (GBZ 188-2014) has played an important role in screening occupational contraindications and preventing occupational diseases since its implementation.

Therefore, this paper mainly discussed the connotation and quantitative standards of organic heart disease, arrhythmia, hypertension in the occupational contraindication cardiovascular disease in the specification for "homogenization".

Quality evaluation of Cnidii Fructus in commodity grade based on theory of "quality evaluation through morphological identification" / 中国中药杂志

From the perspective of market classification of Cnidii Fructus, this paper revealed the scientific connotation of evaluating the quality grade of Cnidii Fructus by its appearance traits. Thirty batches of Cnidii Fructus in different grades were selected as the research objects. The canonical correlation analysis and principal component analysis(PCA) were used to explore the measurement values of 15 appearance traits and intrinsic content indexes. The results of correlation analysis showed that except the aspect ratio, the 5 appearance trait indexes(length, width, 1 000-grain weight, broken grain weight proportion, and chroma) and 9 internal content indexes(the content of moisture, total ash, acid insoluble ash, osthole, imperatorin, 5-methoxy psoralen, isopimpinellin, xanthotoxin, and xanthotol) showed significant correlation to varying degrees. In addition, there was a significant positive correlation between the first typical variable U_1 composed of appearance traits and the first typical variable V_1 composed of internal content indexes(CR_1=0.963, P<0.01). The results of PCA showed that the classification results of appearance traits for 30 batches of Cnidii Fructus were consistent with the actual information of the samples. Under the same analysis conditions, 30 batches of Cnidii Fructus were reclassified by 9 groups of internal content indexes, and the analysis results were consistent. From the classification standard of the appearance traits of the system study, the statistical results of 6 appearance traits of Cnidii Fructus showed a correlation with grades. There was a good correlation between the appearance and the internal content of Cnidii Fructus, and the appearance quality effectively predicted the level of the internal content. There is a certain scientific basis for the quality classification of Cnidii Fructus by main appearance traits. Appearance classification can replace quality grading to realize the "quality evaluation through morphological identification" of Cnidii Fructus.

Analysis and prospects of common problems in clinical data mining of traditional Chinese medicine prescriptions / 中国中药杂志

Mining data from traditional Chinese medicine(TCM) prescriptions is one of the important methods for inheriting the experience of famous doctors and developing new drugs. However, current research work has problems such as to be optimized research plans and non-standard statistics. The main problems and corresponding solutions summarized by the research mainly include four aspects.(1)The research plan design needs to consider the efficacy and quality of individual cases.(2)The significance of the difference in confidence order of association rules needs to be further considered, and the lift should not be ignored.(3)The clustering analysis steps are complex. The selection of clustering variables should comprehensively consider factors such as the frequency of TCM, network topology parameters, and practical application significance. The selection of distance calculation and clustering methods should be improved based on the characteristics of TCM clinical data. Jaccard distance and its improvement plan should be given attention in the future. A single, unexplained clustering result should not be presented, but the final clustering plan should be selected based on a comprehensive consideration of TCM clinical characteristics and objective evaluation indicators for clustering.(4)When calculating correlation coefficients, algorithms that are only suitable for continuous variables should not be applied to binary variables. This article explained the connotations of the above problems based on the characteristics of TCM clinical research and statistical principles and proposed corresponding suggestions to provide important references for future data mining research work.

Reviewing and writing expert consensus in a scientifically rigorous manner / 中华消化外科杂志

The development of medicine has shifted from empirical medicine to evidence-based medicine, providing more scientific and precise clinical evidence for the diagnosis and treat-ment of human diseases, and to guide clinical practice and bring benefits to patients. However, there are still some diseases for which it is difficult to obtain large-scale evidence-based medical evidence for various reasons, especially some rare diseases and difficult and serious diseases. These rare diseases and difficult and serious diseases are often difficult to diagnose and treat in clinical practice, and need guidance and advice from highly qualified experts, thus, various expert consensuses have emerged. The authors analyze the recent expert consensus in the field of digestive diseases at home and abroad, and focus on the methods and pathways for the development of the international common clinical expert consensus. It is proposed that the current stage is in line with China's national condi-tions, based on the international perspective, and mastering the international consensus Delphi pathway, in order to further standardizing the method of developing expert consensus in the clinical field of China, significantly improve the academic level of expert consensus in China, provide scientific, standardized, and international-level expert consensus for the majority of clinical workers, and finally serve the majority of patients and ultimately serving clinical patients.
