RESUMO

ABSTRACT Objective: To analyze the compliance with the commercialization of children's products included in the Brazilian Code of Marketing of Infant and Toddlers Food and Childcare-Related Products (NBCAL) in drugstores in Uberlândia/MG. Methods: A cross-sectional study was carried out in 143 drugstores that sold infant products: infant formula (IF), follow-up IF, nipples, teats, pacifiers and nipple shields; FI for young children, transition foods and cereal-based foods, fluid or powdered milk, modified/similar milks of plant origin and dairy compounds. The location of drugstores in the five geographic sectors was performed by geoprocessing. The data collected were: types of promotion and types of drugstore administration (drugstore chains/drugstores with independent administration). Irregular commercial promotion was expressed as absolute and relative frequencies. Results: Irregular commercial promotion was found in 11.7% of nipples, pacifiers and bottles, in 10.0% of IF and follow-up formula, in 9.5% of IF for young children, in 11.1% fluid or powdered milk, in 25.0% of transition foods and cereal-based foods and in 59.1% of dairy compounds. In commercial drugstore chains, the presence of promotion for dairy (81.8 vs. 28.6%, respectively) was higher than in drugstores with independent administration. The opposite ocurred for fluid or powdered milk, modified and similar milks of plant origin. The downtown and eastern sectors had the highest percentages of promotions (26%). Conclusions: NBCAL violations still occur in drugstores, mainly in the sale of young children's foods and in the commercial network drugstores.


RESUMO Objetivo: Analisar a conformidade da comercialização dos produtos infantis incluídos na Norma Brasileira de Comercialização de Alimentos para Lactentes e Crianças de Primeira Infância, Bicos, Chupetas e Mamadeira (NBCAL) e de compostos lácteos em drogarias de Uberlândia/MG. Métodos: Estudo transversal realizado em 143 drogarias que vendiam produtos infantis: fórmulas infantis (FI) para lactentes, FI de seguimento para lactentes, mamadeiras, bicos, chupetas e protetores de mamilo; FI para crianças de primeira infância, alimentos de transição e alimentos à base de cereais, leites fluidos/em pó, leites modificados/similares de origem vegetal e composto lácteo. A localização das drogarias nos cinco setores geográficos foi realizada por geoprocessamento. Os dados coletados foram: tipos de promoção comercial irregular e tipo de administração da drogaria (rede/independente). As promoções comerciais irregulares foram expressas em frequências absoluta e relativa. Resultados: Verificamos a presença de promoção comercial irregular em 11,7% dos bicos, chupetas e mamadeiras, em 10,0% das FI lactentes/seguimento de lactentes, em 9,5% das FI para crianças de primeira infância, em 11,1% dos leites, em 25,0% de alimentos de transição e em 59,1% dos compostos lácteos. Nas drogarias de rede, a presença de promoção comercial irregular foi maior para compostos lácteos (81,8 vs. 28,6%, respectivamente) e, para leites, foi maior nas drogarias independentes (30,8 vs. 6,0%). Os setores central e leste apresentaram os maiores percentuais de promoção comercial irregular (26%). Conclusões: As violações à NBCAL ainda ocorrem nas drogarias, principalmente para os produtos destinados às crianças de primeira infância, e nas drogarias de rede.

RESUMO

Danggui Sinitang is first recorded in the Treatise on Cold Damage written by ZHANG Zhongjing in the Han dynasty. It is composed of Angelicae Sinensis Radix, Cinnamomi Ramulus, Paeoniae Radix Alba, Asari Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma, Tetrapanacis Medulla, and Jujubae Fructus and serves as a classic formula for treating the syndrome of blood deficiency and cold reversal. This study systematically reviews the records of Danggui Sinitang in ancient Chinese medicine books of various dynasties and the modern clinical applications to probe into the composition, plant species, processing, dosage, decocting method, and indications of Danggui Sinitang, aiming to provide a reference for the development and clinical application of this classic formula. The review of the records showed that there were a variety of records of Danggui Sinitang with different composition, and the composition of this formula listed in the Treatise on Cold Damage has a significant impact on later generations and has been used by medical practitioners throughout history. Although the dosage of some drugs decreased during the Ming and Qing dynasties, the medical practitioners continued to use the original formula. In terms of processing, although there were slight changes in the processing of Angelicae Sinensis Radix, Paeoniae Radix Alba, Glycyrrhizae Radix et Rhizoma, and Tetrapanacis Medulla, the original processing method was inherited. In terms of indications, Danggui Sinitang was designed to treat cold reversal due to blood deficiency and dysentery. Furthermore, it was used to treat headache, convulsive disease, infantile convulsion, and private part adduction in the Ming and Qing dynasties. Nowadays, this formula is mostly used to treat diabetes peripheral neuropathy, rheumatoid arthritis, dysmenorrhea, Raynaud's disease and other diseases. In terms of precautions, ancient physicians believed that Danggui Sinitang should not be taken by pregnant women and should only be used for limb chills caused by blood deficiency and cold coagulation. For limb chills caused by other reasons, this formula should not be used indiscriminately. Modern research has not reported any serious adverse reactions related to this formula. Danggui Sinitang has a definite therapeutic effect. In subsequent research and development, quality control standards of Danggui Sinitang should be established while its safety is ensured, and the related preparations should be developed and applied.

RESUMO

ObjectiveTo explore the possible mechanism of the Yiqi Jiedu formula (YQ) in treating ischemic stroke (IS) from the perspective of the microbial-gut-brain axis (MGBA). MethodRats were randomly divided into five groups, with six in each group, including sham surgery group, model group, and low, medium, and high dose YQ groups (1, 5, and 25 mg·kg-1). Except for the sham surgery group, all other groups were established with a middle cerebral artery occlusion (MCAO) model using the thread occlusion method. The success of modeling was determined through neurobehavioral scoring, and the protective effect of YQ on IS was evaluated. Then, the changes in gut microbiota before and after MCAO modeling and YQ administration were compared using 16S rDNA sequencing technology, and the possible biological pathways related to the effect of this formula were analyzed. The expression of inflammatory factors such as interleukin-6 (IL-6), interleukin-17A (IL-17A), and interleukin-10 (IL-10) in serum was detected by enzyme-linked immunosorbent assay (ELISA). Western blot was used to detect the expression of tight junction proteins ZO-1 and Occludin in brain and intestinal tissue, and hematoxylin-eosin staining (HE) was used to observe pathological changes in the cerebral cortex and colon, so as to validate the possible mechanism of action. ResultYQ significantly improved the neurobehavioral score of MCAO rats (P<0.01) and played a good regulatory role in intestinal microbial disorders caused by enriched pathogens and opportunistic pathogens during the acute phase. Among them, significantly changed microorganisms include Morgentia, Escherichia Shigella, Adlercreutzia, and Androbacter. Bioinformatics analysis found that these bacteria may be related to the regulation of inflammation in the brain. Compared with the blank group, the detection of inflammatory factors in the serum of IS model rats showed an increase in inflammatory factors IL-6 and IL-17A (P<0.01) and a decrease in the content of anti-inflammatory factor IL-10 (P<0.01). Compared with the model group, the content of inflammatory factors IL-6 and IL-17A in the serum of the treatment group decreased (P<0.05), and that of anti-inflammatory factor IL-10 increased (P<0.01). The expression results of barrier proteins ZO-1 and Occludin in brain and intestinal tissue showed that the expression levels of both decreased in IS model rats (P<0.05), while the expression levels of both increased in the treatment group (P<0.05). ConclusionAcute cerebral ischemia can lead to an imbalance of intestinal microbiota and damage to the intestinal barrier, and it can increase intestinal permeability. YQ can regulate intestinal microbiota imbalance caused by ischemia, inhibit systemic inflammatory response, and improve the disruption of the gut-blood brain barrier, preventing secondary cascade damage to brain tissue caused by inflammation. The MGBA may be an important mechanism against the IS.

RESUMO

ObjectiveTo observe the clinical effectiveness and safety of She medicine (畲药) Diren Zishen Formula(地稔滋肾方) combined with acupuncture as adjunctive treatment for primary biliary cholangitis with liver and kidney yin deficiency syndrome. MethodsSeventy patients of primary biliary cholangitis with liver and kidney yin deficiency syndrome were randomly divided into a control group and a treatment group, with 35 patients in each group. The control group received oral ursodeoxycholic acid capsules (250 mg per dose, three times daily). The treatment group received She medicine Diren Zishen Formula oral decoction (one dose daily, 200 ml per dose in the morning and evening, served warm) and acupuncture [bilateral Sanyingjiao (SP6), Taichong (LR3), Ganshu (BL18), Zusanli (ST36), Fenglong (ST17), once daily, 5 consecutive days per week] in addition to the same treatment as the control group. The treatment duration was three months for both groups. Comparisons were made between the two groups before and after treatment for the following parameters, which were four traditional Chinese medicine (TCM) symptoms scores (skin itching, fatigue, jaundice, and flank pain), TCM syndrome scores, liver function indicators including aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT) and total bilirubin (TBiL), liver fibrosis markers including serum laminin (LN), serum hyaluronic acid (HA), serum type Ⅳ collagen (Ⅳ-C) and serum type Ⅲ procollagen (PC-Ⅲ), and inflammatory factor indicators including serum interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α). The effectiveness of TCM syndrome between the two groups was compared and safety evaluations were also conducted after treatment. ResultsA total of 32 cases were finally analyzed in the treatment group, while the control group had 31 cases. The total effective rate of TCM syndrome in the treatment group (87.50%, 28/32) was higher than that in the control group (67.74%, 20/31) (P<0.05). After treatment, the TCM symptom scores, syndrome scores, liver function, and liver fibrosis markers in both groups signi-ficantly decreased, while in the treatment group, the inflammatory factor indicators decreased after treatment, and more decreases were found than those in the control group (P<0.05 or P<0.01). Both groups had good safety, and no adverse reactions were observed. ConclusionThe combination of She medicine Diren Zishen Formula and acupuncture as an adjunctive treatment for primary biliary cholangitis can significantly improve the clinical effectiveness, improve liver function, reduce inflammatory response, and alleviate liver fibrosis, with good safety.

RESUMO

In recent years, data mining algorithms have been widely employed in scientific research within the field of traditional Chinese medicine (TCM). The data mining algorithms are used to effectively handle and analyze the complex data in TCM formulas, providing a rational explanation for the mechanism of action. This method has proven particularly useful in uncovering patterns of compatibility and frequent combinations of herbs in TCM, thereby enhancing the reliability and accuracy of clinical diagnosis, target screening, and the study of new drugs. This paper reviews and analyzes 147 papers on TCM formula research that utilize data mining algorithms. The results indicate that data mining algorithms play a unique advantage in six sub- areas, including the study on the mechanism of action in TCM formula, the dose-efficacy of TCM formulas, the identification of core drugs pairs/groups, mining the relationships among “formulas-drug-symptom”, the discovery of new formulas, and mining the compatibility law. Notably, association rules and clustering algorithms are the most representative.

RESUMO

ObjectiveTo investigate the possible mechanism of Shenqi Jianxin Formula (参芪健心方) in the treatment of chronic heart failure (CHF) from the perspective of pyroptosis. MethodsFifty-two rats were randomly divided into sham operation group (n=8) and modeling group (n=44). In the modeling group, the anterior descending branch of the left coronary artery was ligated to construct CHF rat model. Forty successfully-modelled rats were randomly divided into model group, Entresto group, Shenqi Jianxin Formula group, MCC950 group and the combination group (Shenqi Jianxin Formula plus MCC950), with 8 rats in each group. In Shenqi Jianxin Formula group, 7.4 g/(kg·d) of Shenqi Jianxin Formula was given by gavage, while in Entresto group, 68 mg/(kg·d) of Entresto suspension was given by gavage; in MCC950 group, MCC950 was injected intraperitoneally with 10 mg/kg once every other day, and in the combination group, 7.4 g/(kg·d) of Shenqi Jianxin Formula was given by gavage, and MCC950 was injected intraperitoneally with 10 mg/kg once every other day; 10 ml/(kg·d) of saline was given by gavage in the sham operation group and the model group. After 3 weeks of continuous intervention, serum brain B-type natriuretic peptide (BNP), creatine kinase isoenzyme MB (CK-MB), interleukin 1β (IL-1β), and interleukin 18 (IL-18) levels were detected by ELISA; HE staining and MASSON staining were used to observe pathological changes in rat myocardium. Except for the Entresto group, western blot technique was used to detect the expression of NOD-like receptor protein 3 (NLRP3), caspase-1, and apoptosis-associated speck-like protein possessing a caspase-recruiting domain (ASC); RT-PCR was used to detect the expression of NLRP3 and caspase-1 mRNA. ResultsCompared with the sham operation group, HE staining of rats in the model group showed obvious myocardial injury, while MASSON staining showed increased area of collagen fibrosis, and serum BNP, CK-MB, IL-1β, IL-18, myocardial tissue NLRP3, caspase-1, ASC protein expression and NLRP3, caspase-1 mRNA expression were all elevated (P<0.05). Compared with those in the model group, cardiomyocyte injury of rats and collagen fibrosis area were reduced, and serum BNP, CK-MB, IL-1β, and IL-18 contents were all reduced in Shenqi Jianxin Formula group, Entresto group, MCC950 group, and the combination group; except for Entresto group, myocardial tissue NLRP3, caspase-1, ASC protein expression and NLRP3, caspase-1 mRNA expression were reduced in the remaining three medication group (P<0.05). Compared with Shenqi Jianxin Formula group, the MCC950 group and the combination group showed decreased serum IL-1β and IL-18 content, collagen fibrosis area, myocardial tissue NLPR3, caspase-1 protein expression, and caspase-1 mRNA expression, and decreased ASC and NLRP3 mRNA expression was shown in the combination group (P<0.05). Compared with MCC950 group, collagen fibrosis area was reduced, and serum IL-18 content, NLRP3, caspase-1 mRNA expression were reduced in the combination group (P<0.05). ConclusionShenqi Jianxin Formula can effectively improve the myocardial injury and heart failure in rats with CHF, and its mechanism may be related to the inhibition of cardiomyocyte pyroptosis through NLPR3/Caspase-1 pathway to reduce the level of intramyocardial inflammation. The combined use of MCC950 with Shenqi Jianxin Formula could more effectively inhibite myocardial pyroptosis, with better therapeutic result than single use of each part.

RESUMO

@#COVID-19 infection in pregnant mothers is associated with higher risk of intrauterine growth retardation and premature births. Very low birth weight infants are more susceptible to neurodevelopmental and chronic respiratory problems. An infant delivered at 33 weeks via caesarean section to a COVID-19 Stage 5A positive mother, weighing 1.43kg at birth. She was kept nil by mouth with parenteral nutrition (PN) support since day five of life until referred to dietitian on day 22 of life for enteral nutrition (EN) establishment. Feeding was administered intermittently via oro-gastric Ryles tube. She was kept under non-invasive ventilation (NIV) mode and had difficulty in weaning from ventilation, leading to slow feeding progress. Initially, enteral trophic feeding was administered using premature infant formula fortified with modular products. In the later stage of feeding, modular products were tapered off and the formula was concentrated. Frequency of bowel output when using fortified formula is lesser compared to when using concentrated and supplemented formula. There is no significant difference in renal profile observed in both stages of feeding. Increasing energy intake using easily digestible sources is preferable as opposed to concentrating feeds even further due to concerns about osmolality and excess administration of other solutes. Intermittent bolus feeding mode may have an effect on dependency on oxygen since intermittent feeds can decrease tidal volume, minute ventilation and dynamic compliance. Additional research is necessary to establish optimal caloric density and nutritional compositions of feedings, feeding mechanisms and its’ effect on feeding tolerance.

RESUMO

El tratamiento del defecto epitelial refractario es un reto y está sujeto al desarrollo de estudios preclínicos y clínicos con el objetivo de obtener tratamientos eficaces, entre los que emerge la insulina tópica. El objetivo del presente artículo fue describir la respuesta cicatrizal del epitelio corneal bajo tratamiento con colirio de insulina. Se presentan dos pacientes con diagnóstico de defecto epitelial persistente posúlcera corneal. Se indicó insulina tópica una gota cada 6 horas, con evolución hacia la epitelización corneal total a los 10 días de iniciado el tratamiento. Se sugiere el mecanismo por el cual la insulina promueve la cicatrización corneal al lograr la restauración de los nervios corneales y favorecer la migración de células epiteliales. En ambos casos el colirio de insulina logró la promover la cicatrización epitelial total de la córnea por lo que se es útil en el tratamiento de defecto epitelial persistente.


The treatment of refractory epithelial defect is a challenge and depends upon the development of preclinical or clinical studies aimed at obtaining effective treatments, among which topical insulin emerges. The objective of this article was to describe the healing response of the corneal epithelium under treatment with insulin eye drops. The cases are presented of two patients with a diagnosis of persistent post-corneal ulcer epithelial defect. Topical insulin was prescribed at one drop every six hours, with evolution towards total corneal epithelialization ten days after the treatment started. The mechanism is suggested by which insulin promotes corneal healing, thus restoring corneal nerves and favoring epithelial cell migration. In both cases, the insulin eye drops were able to promote total epithelial healing of the cornea, making it useful in the treatment of persistent epithelial defect.

RESUMO

Purpose: The ideal formula for intraocular lens (IOL) power calculation following cataract surgery in pediatric eyes till date has no answer. We compared the predictability of the Sanders–Retzlaff–Kraff (SRK) II and the Barrett Universal (BU) II formula and the effect of axial length, keratometry, and age. Methods: This was a retrospective analysis of children who were under eight years of age and who underwent cataract surgery with IOL implantation under general anesthesia between September 2018 and July 2019. The prediction error of SRK II formula was calculated by subtracting the target refraction and the actual postoperative spherical equivalent. Preoperative biometry values were used to calculate the IOL power using the BU II formula with the same target refraction that was used in SRK II. The predicted spherical equivalent of the BU II formula was then back?calculated using the SRK II formula with the IOL power obtained with the BU II formula. The prediction errors of the two formulae were compared for statistical significance. Results: Seventy?two eyes of 39 patients were included in the study. The mean age at surgery was 3.8 ± 2 years. The mean axial length was 22.1 ± 1.5 mm, and the mean keratometry was 44.7 ± 1.7 D. The group with an axial length >24 mm showed a significant and strong positive correlation (r = 0.93, P = 0) on comparison mean absolute prediction errors using the SRK II formula. There was a strong negative correlation between the mean prediction error in the overall keratometry group using the BU II formula (r = ?0.72, P < 0.000). There was no significant correlation between age and refractive accuracy using the two formulae in any of the subgroups of age. Conclusion: There is no perfect answer to an ideal formula for IOL calculation in children. IOL formulae need to be chosen keeping in mind the varying ocular parameters.

RESUMO

ABSTRACT OBJECTIVE To review observational studies on the association between breastfeeding (BF) practices and head circumference (HC) of children < 2 years old. METHODS A systematic review was conducted using the following electronic databases of health sciences: PubMed, Latin American and Caribbean Literature in Health Sciences (Lilacs), Web of Science and Scopus. We selected observational studies published in any language from January 01, 2010 to November 19, 2021, from different populations that investigated the association between BF practice and HC among healthy children < 2 years old. Titles and abstracts were screened independently by two evaluators. RESULTS From the 4,229 articles identified, 24 were included in this review: 6 cross-sectional, 17 longitudinal, and 1 case-control. The studies varied in their definition of the variables for BF and in reporting its practice, frequency, duration, and feeding method. Regarding HC, the authors analyzed the mean differences, abnormal values (z-score above + 2SD or below -2SD according to the World Health Organization (WHO) growth standards, 2007), and longitudinal growth parameters. The findings of this review suggest that BF may have a positive relationship with HC at the beginning of life. CONCLUSIONS Our findings suggest that BF, especially exclusive BF, may play a protective role against abnormal HC values in young children. However, more robust evidence with standardized BF indicators and WHO growth standards (2007) are required.

RESUMO

ObjectiveTo observe the clinical efficacy of the Modified Tongmai Anshen Formula (通脉安神方加减, MTAF) in the treatment of stable angina pectoris (SAP) with sleep disorders. MethodsA total of 148 patients suffering from SAP with sleep disorder were included and randomly divided into control group and treatment group, with 74 patients in each group. The control group received conventional western medicine, and the treatment group additionally received MTAF (1 dose per day), both for 4 weeks. The changes in angina pectoris symptoms, traditional Chinese medicine (TCM) syndromes, sleep quality, quality of life, serological indicators including serum intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1), brain-derived nerve growth factor (BDNF) and tyrosine kinase receptor B (TrkB) were compared between groups before and after treatment, and the safety was evaluated. ResultsIn the treatment group and the control group, the total effective rates of TCM syndromes(82.43% vs 52.70%), angina pectoris (79.73% vs 64.86%) and sleep (89.19% vs 68.92%) showing significant difference (P<0.001). After treatment, the total TCM syndrome score, primary symptom score, secondary symptom score, and secondary symptoms sleeplessness, restlessness, tiredness and fatigue individual score, angina pectoris score, PSQI total score and each item score were all significantly reduced in both groups, while the SF-36 single item score significantly increased (P<0.05). The total TCM syndromes and primary symptom scores, secon-dary symptoms sleeplessness, restlessness, tiredness and fatigue individual score, angina pectoris score, time to fall asleep, sleep quality, hypnotic medication, sleep disturbance, daytime dysfunction score and PSQI total score were significantly lower in the treatment group than those in the control group after treatment (P<0.05), while the somatic pain, general health status, social functioning, emotional functioning, mental health, and health change were significantly higher in the treatment group (P<0.05). After treatment, ICAM-1 and VCAM-1 level significantly decreased (P<0.05), and BDNF and TrkB levels increased (P<0.05) in the treatment group, while BDNF level significantly decreased in the control group (P<0.05). The TrkB level was significantly higher in the treatment group compared to the control group after treatment (P<0.05). A total of four adverse events occurred during the treatment, none of which were considered to be related to this study. ConclusionMTAF can significantly improve angina pectoris symptoms, TCM syndromes, sleep quality and quality of life in patients suffering from SAP with sleep disorders, the mechanism of which may be related to the protection of vascular endothelial function and central neurons.

RESUMO

ObjectiveTo explore and establish the liver injury risk prediction model of indirect toxicity of Chinese medicinals under the condition of compound formulas, and provide new ideas and methods for the study of evaluation of liver injury of Chinese medicinals based on indirect toxicity. MethodsTaking Buguzhi (Fructus Psoraleae) pre-parations as model drug, the combined Chinese medicinals with Buguzhi (Fructus Psoraleae) of high frequency are screened out, and their components and action targets were obtained through TCMSP, TCMIP and PharmMapper databases. The association strength value and risk value of Chinese medicinals that acted on the nuclear factor κB (NF-κB) pathway were analyzed. For those having greater values than the median association strength value and risk value were regarded as indirect Chinese medicinals of liver injury risk. In this way, a prediction model of liver injury risk of Chinese medicinals was constructed based on immune activation-related indirect liver injury process (taking NF-κB pathway as an example). And verification of the prediction model was performed using Heshouwu (Radix Polygoni Multiflori) preparations. ResultsThe prediction model of liver injury risk based on important immunoactivated pathway (taking NF-κB pathway as an example) found that Yinyanghuo (Herba Epimedii) (association strength value = 0.18, risk value = 0.25) was a Chinese medicinal with potential risk of indirect liver injury within Buguzhi (Fructus Psoraleae) prepartions, which may increase the risk of liver injury by positively regulating Bruton's tyrosine kinase (Btk) and protein kinase C theta (PKCθ) on NF-κB pathway. Further verification of prediction model by Heshouwu (Radix Polygoni Multiflori) preparations showed that Buguzhi (Fructus Psoraleae) (association strength value = 0.25, risk value = 0.33) and Tusizi (Semen Cuscutae) (Semen Cuscutae, association strength value = 0.34, risk value = 0.33) may increase the liver injury risk of Heshouzu. ConclusionThe liver injury risk prediction model of indirect toxicity of Chinese medicinals has been constructed in this study, providing metho-dological reference for the identification of Chinese medicinals of indirect liver injury risk under the condition of compound formulas.

RESUMO

In this study, ultra-performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS~E) was used to analyze the plasma components of Danzhi Xiaoyao Formula after oral administration. Forty-nine plasma components were found in the serum of rats by comparing the compound extract, drug-containing serum, and blank serum. Components, such as 6-hydroxycoumarin, poricoic acid F, deoxoglabrolide, 30-norhederagenin, kanzonol R, 3',6'-di-O-galloylpaeoniflorin, 16α-hydroxytrametenolic acid, 16-deoxyporicoic acid B, 3-O-acetyl-16α-hydroxytrametenolic acid, and 16α,25-dihydroxydehydroeburiconic acid, were first found in rat serum. Behavioral tests, including the tail suspension test, novel object recognition test, and novelty-suppressed feeding test, were conducted for behavioral analysis. It was confirmed that this formula had therapeutic effects on perimenopausal depression. Furthermore, in combination with the network pharmacology method, 53 core targets including MAPK1, HRAS, AKT1, EGFR, and ESR1 were screened, and these targets participated in 165 signaling pathways, including PI3K-AKT, AMPK, VEGFA, MAPK, and HIF-1. In summary, the potential effects of Danzhi Xiaoyao Formula in treating perimenopausal depression are associated with mechanisms in accelerating inflammation repair, improving neuroplasticity, affecting neurotransmitters, regulating estrogen levels, and promoting new blood vessel formation.

RESUMO

This study comprehensively analyzed the active components of Sanhan Huashi Formula using qualitative and quantitative mass spectrometry techniques, laying the foundation for understanding its pharmacological substance basis. UHPLC-LTQ-Orbitrap-MS and GC-MS technologies were used to analyze and identify the volatile and non-volatile components in Sanhan Huashi Formula. UHPLC-QQQ-MS/MS technology was used to simultaneously determine the content of 27 major active components in the formula. The results showed that 308 major chemical components were identified in Sanhan Huashi Formula, among which 60 compounds were identified by comparing with reference standards, mainly including alkaloids, flavonoids, coumarins, triterpenoid saponins, amino acids, and nucleosides. GC-MS technology preliminarily identified 52 volatile compounds, with γ-eudesmol and β-eudesmol as the main components. The quantitative results demonstrated good linearity(r>0.99) for the 27 active components, indicating the stability, simplicity, and reliability of the established method. Among them, amygdalin, nodakenin, arecoline, ephedrine, and pseudoephedrine had relatively high content and were presumably the main pharmacologically active substances. In conclusion, this study systematically and comprehensively characterized the major chemical components and patterns in Sanhan Huashi Formula, providing a basis for understanding its pharmacological mechanisms and clinical applications.

RESUMO

Based on the CX3C chemokine ligand 1(CX3CL1)-CX3C chemokine receptor 1(CX3CR1) axis, this study explored the potential mechanism by which Zuogui Jiangtang Jieyu Formula(ZGJTJY) improved neuroinflammation and enhanced neuroprotective effect in a rat model of diabetes mellitus complicated with depression(DD). The DD rat model was established by feeding a high-fat diet combined with streptozotocin(STZ) intraperitoneal injection for four weeks and chronic unpredictable mild stress(CUMS) combined with isolated cage rearing for five weeks. The rats were divided into a control group, a model group, a positive control group, an inhibitor group, and a ZGJTJY group. The open field test and forced swimming test were used to assess the depression-like behaviors of the rats. Enzyme-linked immunosorbent assay(ELISA) was performed to measure the expression levels of the pro-inflammatory cytokines interleukin-1β(IL-1β) and tumor necrosis factor-α(TNF-α) in plasma. Immunofluorescence staining was used to detect the expression of ionized calcium-binding adapter molecule 1(Iba1), postsynaptic density protein-95(PSD95), and synapsin-1(SYN1) in the hippocampus. Hematoxylin-eosin(HE) staining, Nissl staining, and TdT-mediated dUTP nick end labeling(TUNEL) fluorescence staining were performed to assess hippocampal neuronal damage. Western blot was used to measure the expression levels of CX3CL1, CX3CR1, A2A adenosine receptor(A2AR), glutamate receptor 2A(NR2A), glutamate receptor 2B(NR2B), and brain-derived neurotrophic factor(BDNF) in the hippocampus. Compared with the model group, the ZGJTJY group showed improved depression-like behaviors in DD rats, enhanced neuroprotective effect, increased expression of PSD95, SYN1, and BDNF(P<0.01), and decreased expression of Iba1, IL-1β, and TNF-α(P<0.01), as well as the expression of CX3CL1, CX3CR1, A2AR, NR2A, and NR2B(P<0.01). These results suggest that ZGJTJY may exert its neuroprotective effect by inhibiting the CX3CL1-CX3CR1 axis and activation of hippocampal microglia, thereby improving neuroinflammation and abnormal activation of N-methyl-D-aspartate receptor(NMDAR) subunits, and ultimately enhancing the expression of synaptic-related proteins PSD95, SYN1, and BDNF in the hippocampus.

RESUMO

This study aimed to investigate the effect and mechanism of Zuogui Jiangtang Qinggan Formula(ZGJTQG) on the glucolipid metabolism of type 2 diabetes mellitus(T2DM) complicated with non-alcoholic fatty liver disease(NAFLD). NAFLD was induced by a high-fat diet(HFD) in MKR mice(T2DM mice), and a model of T2DM combined with NAFLD was established. Forty mice were randomly divided into a model group, a metformin group(0.067 g·kg~(-1)), and high-and low-dose ZGJTQG groups(29.64 and 14.82 g·kg~(-1)), with 10 mice in each group. Ten FVB mice of the same age were assigned to the normal group. Serum and liver tissue specimens were collected from mice except for those in the normal and model groups after four weeks of drug administration by gavage, and fasting blood glucose(FBG) and fasting insulin(FINS) levels were measured. The levels of total cholesterol(TC), triglyceride(TG), and low-density lipoprotein(LDL) were detected by the single reagent GPO-PAP method. Very low-density lipoprotein(VLDL) was detected by enzyme-linked immunosorbent assay(ELISA). Alanine aminotransferase(ALT) and aspartate ami-notransferase(AST) were determined by the Reitman-Frankel assay. The pathological changes in the liver were observed by hematoxylin-eosin(HE) staining and oil red O staining. Real-time fluorescence-based quantitative polymerase chain reaction(real-time PCR) and Western blot were adopted to detect the mRNA and protein expression of forkhead transcription factor O1(FoxO1), microsomal triglyceride transfer protein(MTP), and apolipoprotein B(APOB) in the liver. The results showed that high-dose ZGJTQG could signi-ficantly reduce the FBG and FINS levels(P<0.05, P<0.01), improve glucose tolerance and insulin resistance(P<0.05, P<0.01), alleviate the liver damage caused by HFD which was reflected in improving liver steatosis, and reduce the serum levels of TC, TG, LDL, VLDL, ALT, and AST(P<0.05, P<0.01) in T2DM mice combined with NAFLD. The findings also revealed that the mRNA and protein expression of FoxO1, MTP, and APOB in the liver was significantly down-regulated after the intervention of high-dose ZGJTQG(P<0.05, P<0.01). The above study showed that ZGJTQG could effectively improve glucolipid metabolism in T2DM combined with NAFLD, and the mechanism was closely related to the regulation of the FoxO1/MTP/APOB signaling pathway.

RESUMO

This study aimed to explore the molecular mechanism of Juanbi Qianggu Formula(JBQGF), an empirical formula formulated by the prestigious doctor in traditional Chinese medicine, in the treatment of rheumatoid arthritis based on network pharmacology and cell function experiments. The main active components and targets of JBQGF were obtained through Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and Encyclopedia of Traditional Chinese Medicine(ETCM), and the core targets underwent functional enrichment analysis and signaling pathway analysis. Cytoscape 3.6.0 was used to construct a visualized "active component-target-signaling pathway" network of JBQGF. After screening, nine potential pathways of JBQGF were obtained, mainly including G protein-coupled receptor signaling pathway and tyrosine kinase receptor signaling pathway. As previously indicated, the fibroblast growth factor receptor 1(FGFR1) signaling pathway was highly activated in active fibroblast-like synoviocytes(FLS) in rheumatoid arthritis, and cell and animal experiments demonstrated that inhibition of the FGFR1 signaling pathway could significantly reduce joint inflammation and joint destruction in collagen-induced arthritis(CIA) rats. In terms of the tyrosine kinase receptor signal transduction pathway, the analysis of its target genes revealed that FGFR1 might be a potential target of JBQGF for rheumatoid arthritis treatment. The biological effect of JBQGF by inhibiting FGFR1 phosphorylation was preliminarily verified by Western blot, Transwell invasion assay, and pannus erosion assay, thereby inhibiting matrix metalloproteinase 2(MMP2) and receptor activator of nuclear factor-κB ligand(RANKL) and suppressing the invasion of fibroblasts in rheumatoid arthritis and erosive effect of pannus bone. This study provides ideas for searching potential targets of rheumatoid arthritis treatment and TCM drugs through network pharmacology.

RESUMO

Traditional Chinese medicine(TCM) formula granules are highly praised for the advanced, convenient, and modern use of Chinese medicinal materials. The safety of TCM formula granules has long been a concern of regulatory authorities and the medical industry. A multi-center, prospective, open, non-interventional, and centralized monitoring was carried out for the patients treated with TCM formula granules in 252 medical institutions from February 5, 2020 to April 19, 2022. All the case data and the incidence of adverse drug reactions/events were recorded. This study evaluated the safety of TCM formula granules, aiming to provide a reference for the clinically use. A total of 20 547 patients were included in this study. Four adverse events were recorded, including 3 adverse drug reactions with an adverse drug reaction rate of 0.015%, all of which occurred in the digestive system. There was no serious adverse event, and no factors related to adverse drug reactions/events were identified. The incidence of adverse drug reactions/events associated with China Resources Sanjiu Medical & Pharmaceutical Co., Ltd. TCM formula granules was rare, which proved their safety in clinical use. A comprehensive data mining and objective analysis was carried out for the medicines with high frequency in TCM formula granules, the commonly used medicine pairs and combinations, and departmental medication. The drug use characteristics, prescription rules, and departmental use of TCM formula granules were summarized, which can shed light on the prescription compatibility and clinical application.

RESUMO

Chronic heart failure (CHF) is a severe public health problem with increasing morbidity and mortality, any treatment targeting a single session is insufficient to tackle this. CHF is characterized by reduced cardiac output resulting from neurohumoral dysregulation and cardiac remodeling, which might be related to oxidative stress, inflammation, endoplasmic reticulum stress, apoptosis, autophagy, mitochondrial function, and angiogenesis. These molecular mechanisms interact with each other through crosstalk. Historically, Chinese medicinal herbs have been widely applied in the treatment of CHF, and therapeutic effects of Chinese medicinal herbs and their ingredients have been scientifically confirmed over the past decades. Traditional Chinese medicine (TCM) with multiple components can confront the different pathogenesis of CHF through multiple targets. This review analyzes commonly used TCM patent drugs and TCM decoctions that are applicable to different stages of CHF based on clinical trials. Diverse bioactive ingredients in Chinese medicinal herbs have been found to treat CHF via multiple molecular mechanisms. This review comprehensively covers the key works on the effects and underlying mechanisms of TCM, herbal ingredients and synergistic effects of constituent compatibility in treating CHF, providing additional ideas to address this threat.
