Irregular practices in drugstores in the offer of products for children under three years old / Práticas irregulares em drogarias na oferta de produtos para crianças menores de três anos

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.

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.

Mechanism of Yiqi Jiedu Formula Against Ischemic Stroke Based on Microbial-gut-brain Axis / 中国实验方剂学杂志

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.

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.

Application of data mining algorithms in research on traditional Chinese medicine formula / 中国药房

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.

The Effect of Shenqi Jianxin Formula （参芪健心方） on Cardiomyocyte Pyroptosis in Chronic Heart Failure Model Rats Based on the NLRP3/Caspase-1 Signaling Pathway / 中医杂志

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.

History and Clinical Application of Classic Famous Formula Danggui Sinitang / 中国实验方剂学杂志

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.

Energy Dense Feeding in Premature Infants and Its’ Associated Outcomes (Pemakanan Tumpat Tenaga dalam Bayi Pramatang dan Kesan Berkaitan) / Jurnal Sains Kesihatan Malaysia

@#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.

Insulina tópica en el tratamiento del defecto epitelial persistente posúlcera corneal grave

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.

Intraocular lens formula calculation in pediatric eyes: Do we have an answer? A retrospective comparison between Sanders–Retzlaff–Kraff II and Barret’s formula

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.

Breastfeeding practices and head circumference in young children: a systematic review

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.

Tipos de leite consumidos durante o primeiro ano de vida e estado nutricional de lactentes do Sul do Brasil / Types of milk consumed during the first year of life and nutritional status of infants in Southern Brazil

Resumo Introdução A Organização Mundial da Saúde (OMS) recomenda o aleitamento materno exclusivo até o 6º mês de vida da criança e a sua manutenção com alimentação complementar até pelo menos os 2 anos de idade. Apesar da sua importância, a ingestão de substitutos do leite materno é altamente prevalente, sendo uma preocupação em saúde pública. Objetivo Avaliar a associação entre os tipos de leite ingeridos e o estado nutricional no primeiro ano de vida. Método Estudo longitudinal observacional com crianças brasileiras pertencentes a um estudo multicêntrico. Aos 3, 6, 9 e 12 meses de idade foram investigados os tipos de leite consumidos por meio de questionário de frequência alimentar (QFA) e foi realizada antropometria. As associações brutas e ajustadas foram avaliadas por intermédio de regressão linear. Resultados Das 2.965 duplas de mães-bebês rastreadas, 362 atenderam aos critérios e aceitaram participar do estudo (50% meninos). Aos 12 meses de idade, os maiores escores-z de peso para idade e de peso para comprimento foram observados nos meninos que consumiam apenas fórmula ou apenas leite de vaca. Os maiores escores-z de comprimento para idade foram encontrados entre as meninas que ingeriam apenas fórmula ou apenas leite de vaca aos 9 e 12 meses. Ambos foram comparados àqueles que ingeriam apenas leite materno nas mesmas idades. Conclusão Os tipos de leite consumidos associaram-se ao estado nutricional no primeiro ano de vida, sendo observadas diferenças entre os sexos. Os maiores índices antropométricos nas crianças que não recebiam leite materno chamam a atenção para a persistência futura desses desvios, em direção ao excesso de peso.

Abstract Introduction The World Health Organization (WHO) recommends exclusive breastfeeding up to the 6th month of life of the child and its maintenance with complementary feeding until at least 2 years of age. Despite its importance, the intake of breast milk substitutes is highly prevalent and a public health concern. Objective To evaluate the association between the types of milk ingested and nutritional status in the first year of life. Method Observational longitudinal study with Brazilian children from a multicentric study. At 3, 6, 9, and 12 months of age, the types of milk consumed were investigated using a food frequency questionnaire (FFQ), and anthropometric measurements were performed. Crude and adjusted associations were assessed by linear regression. Results Of the 2,965 pairs of mothers-babies screened, 362 met the criteria and accepted to participate in the study (50% of boys). At 12 months of age, higher weight-for-age and weight-for-length z-scores were observed in boys who consumed only formula or only cow's milk, compared to boys who consumed only breast milk. Higher length-for-age z-scores were found among girls who consumed only formula or only cow's milk at 9 and 12 months, compared to girls who consumed only breast milk at the same ages. Conclusion The types of milk consumed were associated with nutritional status during the first year of life, with differences between boys and girls. The higher anthropometric indexes in children who did not receive breastmilk call our attention to the persistence of such deviations toward excessive weight status in the future.

Los niños obesos tuvieron un tiempo de lactancia exclusiva más corto y consumieron alimentación suplementaria y leche de fórmula por un período de tiempo más largo que los niños con un peso normal.

Introduction: Childhood obesity globally is an unresolved health problem, becoming increasingly present in all countries with not appropriate standard treatment strategies. Objective: To describe the relationship between breastfeeding, complementary feeding and formula milk in childhood obesity. Method: An observational cross-sectional study was conducted in 126 children, aged of 6 months to 2 years, treated at the Hospital General Docente Ambato, Ecuador, in 2019. The variables studied were as follow: age, sex, nutritional status, exclusive breastfeeding duration, time of initiation in complementary feeding and duration providing formula milk. Descriptive statistics and the nonparametric Mann-Whitney U test were applied. Results: Infants between the age of 6 to 12 months (50.8%) and female sex (55.2%) predominated. Of the total of children, 62.1% apply in obese profile, 70.6 % were exclusively breastfed in their early 6 months (2 months less than obese patients). The same behavior was observed in those who received complementary feeding and in those who consumed formula milk for 2.5 months. Conclusions: Most children in the study were classified as obese. Obese children had a short frequency of exclusive breastfeeding and consumed complementary feeding and formula milk for a longer period of time rather than children with normal weight.

Stable Angina Pectoris with Sleep Disorders Treated by Modified Tongmai Anshen Formula （通脉安神方加减）： An Clinical Observation of 74 Cases / 中医杂志

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.

Construction and Application of Liver Injury Risk Prediction Model of Chinese Medicinals based on Indirect Toxicity / 中医杂志

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.

A Novel Chinese Medicine Formula Inhibits Non-small Cell Lung Cancer by Triggering Oxidative Stress Dependent on Pentose Phosphate Pathway / 中国肺癌杂志

BACKGROUND@#Non-small cell lung cancer (NSCLC) is one of the most lethal malignancies worldwide. A novel Chinese medicine formula-01 (NCHF-01) has shown significant clinical efficacy in the treatment of NSCLC, but the mechanism of this formula in the treatment of NSCLC is not fully understood. The aim of this study is to investigate the molecular mechanism of NCHF-01 in inhibiting NSCLC.@*METHODS@#Lewis lung cells (LLC) tumor bearing mice were established to detect the tumor inhibitory effect of NCHF-01. The morphological changes of tissues and organs in LLC tumor-bearing mice were detected by hematoxylin-eosin (HE) staining. NSCLC cells were treated by NCHF-01. The effects of cell viability and proliferation were detected by MTT and crystal violet staining experiment. Flow cytometry was used to detect cell cycle, apoptosis and reactive oxygen species (ROS). Network pharmacology was used to predict the mechanism of its inhibitory effect of NSCLC. Western blot and immunohistochemistry (IHC) were used to detect the expression of related proteins.@*RESULTS@#NCHF-01 can inhibit tumor growth in LLC tumor-bearing mice, and has no obvious side effects on other tissues and organs. NCHF-01 could inhibit cell viability and proliferation, induce G2/M phase arrest and apoptosis, and promote the increase of ROS level. Network pharmacological analysis showed that NCHF-01 exerts anti-NSCLC effects through various biological processes such as oxidative stress and central carbon metabolism. NCHF-01 can reduce the protein expression and enzyme activity of the key enzymes 6-phosphate glucose dehydrogenase (G6PD) and 6-phosphogluconate dehydrogenase (6PGD) in the pentose phosphate pathway (PPP).@*CONCLUSIONS@#NCHF-01 can inhibit NSCLC through oxidative stress dependent on the PPP.

The traditional Chinese medicines treat chronic heart failure and their main bioactive constituents and mechanisms

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.

New insights for infection mechanism and potential targets of COVID-19: Three Chinese patent medicines and three Chinese medicine formulas as promising therapeutic approaches / 中草药·英文版

The coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with high pathogenicity and infectiousness has become a sudden and lethal pandemic worldwide. Currently, there is no accepted specific drug for COVID-19 treatment. Therefore, it is extremely urgent to clarify the pathogenic mechanism and develop effective therapies for patients with COVID-19. According to several reliable reports from China, traditional Chinese medicine (TCM), especially for three Chinese patent medicines and three Chinese medicine formulas, has been demonstrated to effectively alleviate the symptoms of COVID-19 either used alone or in combination with Western medicines. In this review, we systematically summarized and analyzed the pathogenesis of COVID-19, the detailed clinical practice, active ingredients investigation, network pharmacology prediction and underlying mechanism verification of three Chinese patent medicines and three Chinese medicine formulas in the COVID-19 combat. Additionally, we summarized some promising and high-frequency drugs of these prescriptions and discussed their regulatory mechanism, which provides guidance for the development of new drugs against COVID-19. Collectively, by addressing critical challenges, for example, unclear targets and complicated active ingredients of these medicines and formulas, we believe that TCM will represent promising and efficient strategies for curing COVID-19 and related pandemics.

Bushen Jianpi Jiedu Liyan Formula Regulates Homing-associated Cell Adhesion Molecules in Rat Model of IgA Nephropathy / 中国实验方剂学杂志

ObjectiveTo investigate the effect of Bushen Jianpi Jiedu Liyan formula on the expression of integrin alpha 4 beta 1 （α4 β1）， vascular cell adhesion molecule-1 （VCAM-1）， stromal-derived factor-1 （SDF-1）， and chemokine receptor-4 （CXCR4） in the small intestine and bone marrow of the rat model of immunoglobulin A（IgA） nephropathy. MethodA total of 120 male SD rats were used to establish the IgA nephropathy model by intragastric administration of bovine serum albumin （BSA）， subcutaneous injection of CCl4， and tail vein injection of lipopolysaccharide （LPS）. The successfully modeled rats were randomized into blank， model， lotensin （63 mg·kg-1）， and low-， medium-， and high-dose （10.4， 20.81， 41.62 g·kg-1， respectively） Bushen Jianpi Jiedu Liyan formula groups （n=16）. The rats were treated with corresponding drugs according to their body weight. After 7 weeks of administration， the rats were sacrificed for the collection of samples， and the protein and mRNA levels of α4 β1， VCAM-1， SDF-1， and CXCR4 in the small intestine and bone marrow were determined by immunohistochemistry and real-time fluorescence quantitative polymerase chain reaction， respectively. ResultCompared with the blank group， the model group showed increased red blood cell count in the urine at the 10th， 12th， 14th， 16th weeks （P<0.01）， and such increases were reduced in the drug intervention groups （P<0.05）， especially in the medium-dose Bushen Jianpi Jiedu Liyan formula group （P<0.05）. Compared with those in the blank group， the protein levels of α4 β1， VCAM-1， SDF-1， and CXCR4 in the intestinal lamina propria in the model group were up-regulated （P<0.05）， and such un-regulations were inhibited in the drug intervention groups （P<0.05）. Compared with the model group， medium-dose Bushen Jianpi Jiedu Liyan formula down-regulated the protein levels of SDF-1 and CXCR4 in the intestinal lamina propria （P<0.05）. Compared with the blank group， the model group showed down-regulated mRNA levels of α4 β1 and SDF-1 and up-regulated mRNA levels of VCAM-1 and CXCR4 （P<0.05）. Compared with the model group， the drug intervention groups showed down-regulated mRNA levels of SDF-1 and CXCR4 （P<0.05）. ConclusionBushen Jianpi Jiedu Liyan formula regulates the expression of α4 β1， VCAM-1， SDF-1， and CXCR4 in the intestinal lamina propria to inhibit the homing effect of plasma cells， which may be associated with the Toll-like receptor-mediated activation of immune response. Bushen Jianpi Jiedu Liyan formula can down-regulate the expression of adhesion molecules to inhibit the proliferation of plasmocytes in circulation， so as to reduce the renal injury of IgA nephropathy.
