RESUMEN

El crecimiento del número de organizaciones criminales y su complejidad, en la variedad conceptual, las implicancias teóricas y sus desafíos empíricos, han dificultado a los investigadores la generación de suficientes teorías, estudios de causas y escalas que permitan una categorización y explicación de sus fenómenos. La caracterización de estas organizaciones y el abordaje de su definición resultan complejos tanto por la diversidad de sus impactos sociales como por lo frondoso de las áreas temáticas que la abordan. Este estudio muestra las tendencias de investigación y estudio de las organizaciones criminales mediante la realización de una revisión sistemática de literatura de los años 2022 y 2023, utilizando el método PRISMA y explorando las tendencias actuales en la investigación académica y producción bibliográfica sobre el tema.


The growth in the number of criminal organisations and their complexity, in terms of conceptual variety, theoretical implications and empirical challenges, have made it difficult for researchers to generate sufficient theories, studies of causes and scales to categorise and explain the phenomena. The characterisation of these organisations and the approach to defining them is complex both because of the diversity of their social impacts and because of the broad range of thematic areas they address. This study shows the trends in research and study of criminal organisations by conducting a systematic literature review of the years 2022 and 2023, using the PRISMA method and exploring current trends in academic research and bibliographic production on the subject.

RESUMEN

Screening and evaluating the diseases responding specifically to traditional Chinese medicine (TCM) will help to highlight the advantages of TCM treatment, and the evaluation method should be standardized with consideration to the unique characteristics of the diseases. The incidence of Sjögren's Syndrome (SS) is increasing year by year, while the pathogenesis of this disease remains unclear. Modern therapies for this disease include biological agents and immunosuppressants, which generally have unsatisfactory efficacy. The TCM treatment of SS focuses on the harmony of the physical and mental health. The Rheumatology Branch of the China Association of Chinese Medicine organizes experts in TCM, Western medicine, and evidence-based medicine to form working groups. Delphi method and bibliometric method were used for analysis, and SS was selected as a disease responding specifically to TCM. Furthermore, the evaluation system was established for this disease, and the consensus regarding this disease was reached after seminar discussion. This paper summarized the whole process of the evaluation of the advantages of TCM treatment of SS. First, because TCM atomization is widely used in clinical practice and enriches TCM administration methods, this therapy is included after other non-drug therapies were taken as characteristic therapies. Second, the evaluation indicators of therapeutic effect should be determined with consideration to international acceptance and the current research status. Third, the expression method should be accurate, standardized, and objective, highlight the natural advantages of TCM, and avoid arbitrary extension. This paper provides a reference for clinicians to explore other diseases responding specifically to TCM.

RESUMEN

OBJECTIVE To establish a method for the content determination of 11 components such as protodioscin in Guge fengtong tablets, and to evaluate the comprehensive quality of Guge fengtong tablets by combining with chemometric analysis and entropy weight-technique for order preference by similarity to ideal solution (EW-TOPSIS) method. METHODS HPLC method was adopted. The determination was performed on Agilent Eclipse Plus C18 column with a mobile phase consisted of acetonitrile- 0.2% phosphoric acid solution at the flow rate of 1.0 mL/min by gradient elution. The column temperature was set at 30 ℃ . The detection wavelengths were set at 203 nm (0-28 min, protodioscin, methyl protodioscin, pseudoprotodioscin, dioscin) and 280 nm (28-60 min, catechin, epicatechin, liquiritigenin, medicarpin, 6-gingerol, 8-gingerol, 10-gingerol); the sample size was 10 μL. Using epicatechin as the internal reference, quantitative analysis of multi-components by single marker (QAMS) method was used to determine the contents of protodioscin, methyl protodioscin, pseudoprotodioscin, dioscin, catechin, liquiritigenin, medicarpin, 6-gingerol, 8-gingerol and 10-gingerol, which were compared with the results of the external standard method. SPSS 26.0 software and SIMCA 14.1 software were used for principal component analysis and orthogonal partial least squares-discriminant analysis, with variable importance in projection (VIP) value greater than 1 as the standard, to screen for differential markers that affect the quality; the EW-TOPSIS method was adopted to evaluate the quality of 15 batches of samples comprehensively.RESULTS The contents of protodioscin, methyl protodioscin, pseudoprotodioscin, dioscin, catechin, liquiritigenin, medi-carpin, 6-gingerol, 8-gingerol and 10-gingerol determined by HPLC combined with QAMS were 6.330-10.863, 1.150-2.274, 0.431- 0.740, 2.818-4.823, 0.826-1.510, 0.043-0.094, 0.079-0.231, 0.479-1.020, 0.146-0.288, 0.118-0.318 mg/g, respectively; there were no statistical significances, compared with the external standard method (P>0.05). A total of 15 batches of samples were clustered into 3 groups, with S1-S6, S7-S10, and S11-S15 clustered into one group, respectively. The VIP values of protodioscin, epicatechin, dioscin and 6-gingerol were greater than 1. Euclidean closeness values of the optimal solution (C)i for 15 batches of samples were 0.163 5 to 0.703 7, and Ci values of S11-S15 were all higher than 0.6. CONCLUSIONS The established QAMS method is accurate and simple, and can be used for comprehensive quality evaluation of Guge fengtong tablets, by combining with chemometric analysis and EW-TOPSIS method. Protodioscin, epicatechin, dioscin and 6-gingerol are the differential markers that affect the quality of Guge fengtong tablets. Samples S11-S15 have better quality.

RESUMEN

It has become an industry consensus that self-assembled nanoparticles (SAN) are formed by molecular recognition of chemical components in traditional Chinese medicine during the decoction process. The insoluble components in the decoction are mostly in the form of nanoparticles, which can improve the problem of poor water solubility. However, the transfer rate of these insoluble components in the decoction is still very low, which limits the efficacy of the drug. This study aimed to refine the traditional decoction self-assembly phenomenon. The self-assembled nanoparticles were constructed by micro-precipitation method (MP-SAN), and characterized by particle size, zeta potential, stability index and morphology. The formation of MP-SAN and alterations in related physicochemical properties were evaluated using modern spectroscopic and thermal analysis techniques. The quality value transmitting pattern of lignan components within the MP-SAN was assessed via high performance liquid chromatography (HPLC). The MP-SAN showed sphere-like structure with uniform morphology, particle size of (245.3 ± 3.2) nm, polydispersity index (PDI) of (0.13 ± 0.03), zeta potential of (-48.9 ± 5.9) mV and stability index (SI) of (86.05% ± 2.27%). Comprehensive analyses using ultraviolet visible spectroscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry, and other techniques confirmed molecular recognition between the decoction and ethanol extraction, leading to electron rearrangement under the influence of non-covalent bonding. This resulted in the formation of nanoparticles possessing superior thermal stability. As determined by HPLC, the encapsulation rates of the index components in the MP-SAN were all greater than 75% (dehydrodiconiferyl alcohol: 77.00%; herpetolide A: 78.57%; herpetrione: 94.53%), and the transfer rates were all higher than 65% (dehydrodiconiferyl alcohol: 96.01%; herpetolide A: 67.86%; herpetrione: 65.55%), which were 1.34, 1.38 and 4.81 times compared with those of the traditional decoction. In summary, this study successfully constructed the MP-SAN based on micro-precipitation method to achieve high transfer rate and high encapsulation rate of insoluble components in docoction, which provides a pharmaceutics idea for the efficient utilization of pharmacodynamic substance basis of traditional Chinese medicine.

RESUMEN

ObjectiveThree methods were applied to conduct occupational health risk assessment for the working positions exposed to silicon dusts in a sanitary ceramic manufacturing factory, and the evaluation results were compared to explore the applicability of different occupational health risk assessment methods. MethodsOne large sanitary ceramic product manufacturing enterprise in Songjiang District, Shanghai was selected to conduct occupational health risk assessment for the working positions exposed to silicon dusts, using occupational hazard risk index evaluation method, exposure ratio evaluation method, and International Council on Mining and Metals (ICMM) quantitative occupational health risk assessment method . The consistency of the evaluation results of the three methods was tested using weighted Kappa method. ResultsFourteen working positions exposed to silicon dusts were identified, and three positions had excessive dust concentration: composite forming position of phase 2 workshop (0.80 mg·m-3), addition forming position of phase 2 workshop (1.00 mg·m-3), and glazing position of 1F in phase 2 workshop (1.50 mg·m-3), with an excessive rate of 21.42%. The occupational hazard risk index evaluation method assessed 6 positions with no harm, 6 positions with mild harm, and 2 positions with moderate harm. The ICMM quantitative occupational health risk assessment method assessed 6 positions with potential risks, 2 positions with tolerable risks, and 6 positions with intolerable risks. The exposure ratio evaluation method assessed 8 positions with medium risk, 5 positions with high risk, and 1 position with extremely high risk. The consistency test results of the three evaluation methods were poor. The Kappa coefficient between the occupational hazard risk index evaluation method and the ICMM quantitative occupational health risk assessment method was 0.15. The Kappa coefficient between the occupational hazard risk index evaluation method and the exposure ratio evaluation method was -0.09. The Kappa coefficient between the ICMM quantitative occupational health risk assessment method and the exposure ratio evaluation method was 0.04. The RR values obtained by the three evaluation methods were significantly correlated: the correlation coefficients between RRICMM quantitative assessment method and RRexposure ratio evaluation method, RROccupational hazard risk index evaluation method and RRICMM quantitative assessment method, RROccupational hazard risk index evaluation method and RRexposure ratio evaluation method were 0.915, 0.604, and 0.594, respectively. The correlation between the assessment result level and CTWA was strong. ConclusionThe occupational hazard risk index evaluation method is suitable for the working positions with low silicon dust exposure concentration, the ICMM quantitative occupational health risk assessment method and the exposure ratio evaluation method are suitable for the positions with high silicon dust exposure concentration, but all these three evaluation methods have limitations. It is more reasonable to use multiple methods at the same time in actual evaluation work.

RESUMEN

Due to the difference between the system of weights and measures, and the dosage of clinical prescriptions of traditional Chinese medicine in various historical periods, the dosage and conversion standard of prescriptions in past dynasties are different. Therefore, when discounting the dosage of famous classical formulas, the principles of inheriting the essence, making the past serve the present, linking the past and the present, and forming a consensus should be followed, firstly, the dosage of the prescription was converted according to the weights and measures system of the past dynasties. If the converted dosage significantly exceeds the provisions of the 2020 edition of Chinese Pharmacopoeia, then on the premise of ensuring that the proportion of the original prescription drug dosage remains unchanged, the conversion shall be based on expert consensus and drug safety evaluation. For drugs measured in non-standard units, a conversion range is provided based on comprehensive literature analysis and physical measurements. For the conversion of service volume, the original text was used as the basis for the conversion with reference to the measurement standards of different eras. If the original dosage is not clear, the converted dosage will be determined based on the historical evolution of the formula, referring to relevant ancient books, and combining modern applications. Eventually, the converting standard for famous classical formulas was determined as follows:during the Han and Tang dynasties, one Liang(两) was equivalent to 13.8 g and one Sheng(升) was equivalent to 200 mL, in the Tang dynasty, one Fen(分) was equivalent to 3.45 g, during the Song, Jin and Yuan dynasties, one Qian(钱) was equivalent to 4.13 g and one Zhan(盏) was equivalent to 300 mL, during the Ming and Qing dynasties, one Qian(钱) was equivalent to 3.73 g, and one Bei(杯) and one Zhong(盅) were equivalent to 200 mL. For drugs recorded in non-standard units of measurement, it is necessary to conduct actual measurements to determine their conversion standards based on comprehensive analysis to determine their origin. If necessary, different records of the dosage of drugs with the same or similar efficacy and indications in medical books of similar ages can be used to assist in determining the conversion standards. The analysis of the principle of dosage conversion for Chinese medicine is helpful for the clinical application and development of famous classical formulas.

RESUMEN

ObjectiveTo investigate the attenuating effect of Dioscoreae Bulbiferae Rhizoma(DBR) processed with Phaseoli Radiati Semen(PRS) juice, and explore the attenuating mechanism based on ferroptosis of the main toxic target organ. MethodSixty male ICR mice were randomly divided into blank group, DBR group, water roasted DBR group(hereinafter referred to as water group), PRS juice-roasted DBR group 1(DBR-PRS 10∶1, stuffy moistening for 40 min, stir-fried at 130 ℃ for 18 min, hereinafter referred to as group 1), PRS juice-roasted DBR group 2(DBR-PRS 10∶1, stuffy moistening for 80 min, stir-fried at 100 ℃ for 14 min, hereinafter referred to as group 2), PRS juice-roasted DBR group 3(DBR-PRS=20∶3, stuffy moistening for 40 min, stir-fried at 160 ℃ for 14 min, hereinafter referred to as group 3). The raw and processed groups of DBR were gavaged with their corresponding 95% ethanol extract at a dose of 3 g·kg-1·d-1, while the blank group was gavaged with an equal volume of 0.5% sodium carboxymethyl cellulose, once a day for 14 consecutive days. Hematoxylin-eosin(HE) staining was used to observe the histopathological changes of mouse liver. Alanine aminotransferase(ALT) and aspartate aminotransferase(AST) levels in serum, as well as malondialdehyde(MDA), ferrous ions(Fe2+), reduced glutathione(GSH) and superoxide dismutase(SOD) levels in liver tissue were detected by the biochemical detection. Western blot was used to detect the expression of iron key proteins such as ferritin heavy chain 1(FTH1) and glutathione peroxidase 4(GPX4). ResultHE staining results showed that the liver tissue structure of the blank group was clear, the morphology of hepatocytes was normal, the cytoplasms of hepatocytes in the DBR group and water group were loose and vacuolar, with obvious pathological damages, and the pathologic damages of mice in the group 1-3 were significantly improved. Compared with the blank group, the levels of ALT, AST, MDA and Fe2+ in mice from the DBR group were significantly increased(P<0.01), while GSH and SOD levels were significantly reduced(P<0.01), and the protein expression levels of FTH1 and GPX4 were significantly decreased(P<0.01). Compared with the DBR group, the ALT, AST,MDA and Fe2+ levels of mice in the group 1-3 were significantly reduced(P<0.05, P<0.01), the GSH and SOD levels and the protein expression levels of FTH1 and GPX4 were significantly increased(P<0.01). Compared with the water group, the AST and MDA levels of mice in the group 1-3 were significantly reduced(P<0.05, P<0.01), the SOD level significantly increased(P<0.05, P<0.01), the FTH1 protein expression significantly increased(P<0.01), and the serum ALT level of mice in the group 2-3 significantly reduce(P<0.01), Fe2+ level significantly reduced(P<0.01), GSH level significantly increased(P<0.05, P<0.01), and GPX4 protein expression significantly increased(P<0.05, P<0.01). Among the group 1-3, the group 3 had the best detoxification effect. ConclutionProcessing with PRS juice can reduce the liver injury induced by DBR, and the mechanism may be related to the inhibition of ferroptosis in the liver.

RESUMEN

Background Healthy lifestyle is one of the important factors affecting individual health. How to promote residents' cognition of healthy lifestyle has become an urgent practical problem for the whole society. However, there is no residents' healthy lifestyle cognitive indexes available with consideration of carbon peaking and carbon neutrality. Objective To construct a cognitive index system for providing effective assessment on residents' cognition of healthy lifestyle under the background of carbon peaking and carbon neutrality. Methods Based on the health belief model, a preliminary cognitive index system of residents' healthy lifestyle under the background of carbon peaking and carbon neutrality was proposed after literature study and relevant policy review. Then three rounds of indicator importance evaluation and screening by Delphi method were conducted before the index system was finally constructed. The weights of all levels of indicators were determined using analytic hierarchy process. In addition, a self-assessment questionnaire was developed based on the index system. The questionnaire was utilized to conduct a survey among 200 residents by convenience sampling in Shenyang, Liaoning Province from November to December 2021. The survey was used to examine the reliability and validity of the indicator system. Results The effective recovery rates of the three rounds of Delphi method were all 100%. The authority coefficient was 0.84. The Kendall's W consistency test showed good expert consistency (P<0.001). Finally, a cognitive index system of residents' healthy lifestyle under the background of carbon peaking and carbon neutrality was initially constructed, including 4 first-level indicators, 8 second-level indicators, and 35 third-level indicators. Among them, the weights of the first-level indicators were 0.4541 for practice cognition, 0.2248 for benefit and obstacle cognition, 0.1626 for action clue cognition, and 0.1585 for risk cognition, respectively. The correlation coefficients between each indicator were from 0.586 to 0.977 (P<0.01). The overall Cronbach's α coefficient was 0.95, indicating high reliability. Invited experts agreed that the entries were representative and the content validity of the constructed indicator system was good. The factor analysis also showed that the structure validity was good. Conclusion The proposed index system for residents' cognition of healthy lifestyle show good reliability and validity, which can be used as an effective assessment tool for residents' healthy lifestyle cognition under the background of carbon peaking and carbon neutrality. It can provide a scientific and theoretical basis for promoting residents' cognition and practice of healthy lifestyle.

RESUMEN

Simmering method is one of the traditional processing methods of Chinese materia medica, which has been documented in the herbal literature and medical books of the past dynasties and has a great variety, but at present, there are not many specific varieties of Chinese materia medica involved, and there are few related researches. By reviewing the ancient and modern related information, the authors have organized and analyzed the historical evolution, processing purpose, modern representative Chinese materia medica(processing technology, quality evaluation, pharmacological research) of simmering method. After sorting out, it was found that the simmering method was widely used in ancient times, which was first seen in Huashi Zhongzangjing of the Eastern Han dynasty, and was enriched and developed through the Tang, Song, Jin, Yuan, Ming and Qing dynasties, and entered its heyday in Ming and Qing dynasties along with the economic prosperity and development of the Ming dynasty, involving as many as 159 varieties of Chinese materia medica, and gradually perfecting the processing theory of the simmering method. However, the number of varieties that still use the simmering method in modern times significantly decreased. The main purposes of using simmering method in modern Chinese materia medica are to reduce adverse reactions, moderate medicinal properties, enhance therapeutic effects, remove non-medicinal parts, and facilitate further processing, etc. This paper combed the key information of simmering methods for Chinese materia medica from ancient to modern times, which can provide a literature basis for the clinical application and modern research of simmered products of Chinese materia medica.

RESUMEN

To construct a simple and two-way interactive doctor-patient communication mode, in order to provide guidance tools for doctor-patient communication, improve the effectiveness of doctor-patient communication for cancer patients, optimize medical experience, reduce doctor-patient disputes, and provide new perspectives and ideas for the study of doctor-patient communication. Literature review and qualitative research were used to construct the index framework of ESER doctor-patient communication model, and Delphi method was used to revise and improve the index content, and evaluate its reliability and validity. The results showed that after two rounds of expert letter consultation, the final ESER doctor-patient communication mode was established, including 4 primary-level indicators, 8 second-level indicators and 40 third-level indicators. The positive coefficient of experts was 100% in both rounds. The authority coefficient of experts was 0.85 in the first round and 0.91 in the second round, indicated a high degree of overall authority. Coefficient of variation (CV) were less than 0.25, and the Kendall’s W coefficient for significant χ2 test, P values were less than 0.05, which was statistically significant. It can be considered that the coordination degree of experts was high; Cronbach’s α coefficients in the first and second rounds of importance evaluation were 0.952 and 0.971, respectively, which indicated that the index framework had good reliability and validity.

RESUMEN

Refractory angina is characterized by recurrent and persistent angina with a duration of not less than three months, which is related to reversible ischemia and hypoxia caused by coronary stenosis and obstruction. It mainly involves obstructive coronary artery disease and non-obstructive coronary artery disease with coronary artery spasm and coronary microvascular dysfunction. “Stasis and toxin” play an important role in the pathogenesis of cardiovascular diseases. The pathogenesis of stasis and toxin is stubborn filthy turbidity featured by slow accumulation and sudden onset,and rapid changes,which coincides with the characteristics of refractory angina which is complex and changeable,prolonged and difficult to cure. The pathogenesis of refractory angina involves a combination of underlying deficiency and excessive manifestation, with "stasis and toxin" playing a crucial role as an important pathological factor in the whole process of refractory angina. Traditional Chinese medicine (TCM) employs a holistic approach known as "activating blood circulation and removing toxins", which is supplemented by various methods to tonify Qi and warm Yang, nourish the kidneys and invigorate the spleen, clear heat and transform phlegm. This approach applies anti-inflammatory measures, regulates lipid metabolism, inhibits oxidative stress and thrombus formation, protects endothelial function in blood vessels, as well as establishes collateral circulation for the prevention and treatment of refractory angina. Therefore,based on the theory of "stasis and toxin",combined with TCM theory and modern medical research,this paper discusses the pathogenesis of refractory angina and the prevention and treatment strategy of TCM,and elucidates the reasons for the difficulty in curing refractory angina and the relationship between refractory angina and common angina pectoris,coronary microvascular dysfunction,coronary artery spasm and obstructive coronary artery disease,hoping to provide certain theoretical basis and clinical ideas for the prevention and treatment of refractory angina with TCM.
