RESUMEN
Aim To explore the possible mechanism of "component-target-pathway" of Radix Hedysari against target organ damage caused by radiotherapy and chemotherapy, and to verify the " dose-effect" relationship of the main active components. Methods TCMSP, Uniprot, Swiss Target Prediction, GeneCards, Cytoscape, Omicshare and other platforms were used for network pharmacology analysis. Autodock, Pymol and Ligplot were used for molecular docking. The water extract of Radix Hedysari was used for animal experiment verification. The contents of eight main components were determined by HPLC. Results Four active components, eight key targets and four key pathways of Radix Hedysari were identified to resist the damage of target organs caused by radiotherapy and chemotherapy. Molecular docking showed that formononetin and quercetin had good binding activity with HSP90AA1, naringenin and MAPK3, and ursolic acid and TP53. Animal experiments showed that gastrointestinal factors MTL and VIP increased significantly, liver and kidney factors Cr, BUN, AST and ALT decreased significantly, inflammatory factor IL-10 increased significantly and TNF-a decreased significantly. The content of ononm was the highest (2 . 884 8 µg • g "
RESUMEN
Objective To provide a reference for avoiding the harm to critical target organs following considerable inhalation exposure to the transuranium element americium (Am) as well as post-accident decorporation or other radiation protection measures. Methods We established calculation programs based on the generic criteria for internal radiation emergency preparedness and response in the IAEA Safety Guide No.GSG-2 and current new ICRP biokinetic models and parameters, taking an inhalation of 241Am (activity mean aerodynamic diameter of 5 μm, σ = 2.5) by an adult worker as an example; and determined that the critical target organs were the lung AI region, red bone marrow, and the main source organs leading to acute doses to the critical target organs were the lung AI region, blood, and trabecular bone surface. Results The retention fractions in the main source organs over time after 241Am inhalation were calculated. Conclusion After being absorbed into blood, Am moves quickly to other parts, and Am of different absorption types shows similar early changes in retention fractions in blood: the retention fractions of Am of S, M, and F types in blood peak around 0.03 d, and then halve around 1.7 d. Inhaled Am shows different changes over time in retention fractions in the lung AI region and trabecular bone surface in the early stage: the retention fractions of S- and M-type Am in the lung AI region change little with time, while F-type Am transfers quickly from the lung to blood; In trabecular bone surface, S-type Am increases quickly in the first 7 d, M-type Am gradually increases mainly in the first 2 weeks, and F-type Am increases quickly in the first 2 d.
RESUMEN
Objective:To summarize the correlation between anterior pituitary function and tumor size in patients with different hormone-secreting pituitary adenomas.Methods:This was a retrospective case series study. The clinical data of 1 946 patients with pituitary adenoma hospitalized in the First Medical Center of Chinese PLA General Hospital from January 1, 2005, to December 31, 2020, were collected. The correlation between tumor size and anterior pituitary hormone levels was analyzed using Spearman rank correlation analysis in different types of pituitary adenomas.Results:The median age of the 1 946 patients was 45.1 years, of which 857 (44.0%) were men. The maximum tumor diameter of the patients [ M ( Q1, Q3)] was 22 (14, 30) mm. Tumor size in nonfunctioning adenomas ( n=1 191) was negatively correlated with adrenocorticotropic hormone (ACTH) ( r=-0.11, P<0.001), growth hormone ( r=-0.13, P<0.001), and luteinizing hormone (men: r=-0.26, P<0.001, women: r=-0.31, all P<0.001). The tumor size of somatotropic adenomas ( n=297) was positively correlated with growth hormone ( r=0.46, P<0.001), but negatively correlated with male testosterone ( r=-0.41, P<0.001). The tumor size of ACTH-secreting pituitary adenomas ( n=155) was positively correlated with the ACTH level at 8∶00 AM ( r=0.25, P<0.001); however, no correlation was found with cortisol at 8∶00 AM ( P>0.05). The tumor size of prolactinomas ( n=303) was positively correlated with the prolactin level (men: r=0.34, P=0.001; women: r=0.13, P=0.070). Conclusions:The correlation between the function of the anterior pituitary and size of the tumor depends on the cellular origin of the pituitary adenoma and specific type of hormone secretion. In somatotroph adenomas, ACTH-secreting pituitary adenomas, and prolactinomas, there is a positive correlation between tumor size and level of hormones secreted by the corresponding tumors. In patients with nonfunctioning adenomas, the tumor size was negatively correlated with the hormone levels of the pituitary-adrenal and pituitary-growth hormone axes.
RESUMEN
Hypertension is a common cardiovascular disease. At present， the prevalence and mortality of hypertension in China continue to rise， the morbidity and mortality of complications remain high. The continuous increase of blood pressure can cause damage to multiple target organs such as heart， brain， kidney and blood vessels. This article reviews the research progress of signal pathways related to the prevention and treatment of hypertension target organ damage by traditional Chinese medicine， and summarizes six signal pathways related to RhoA/ROCK， renin-angiotensin-aldosterone system， endothelin-1/nitric oxide， transforming growth factor-β1/Smads， phosphatidylinositide 3-kinases/protein kinase B， and Toll-like receptor 4/nuclear transcription factor-κB， in order to provide theoretical evidence for further research on clinical diagnosis and treatment of hypertension and its target organ damage.
RESUMEN
Aim To investigate the protective effect of hesperidin (HES) on cardiorenal damage induced by DOCA/Salt hypertension and the underlying mechanisms. Methods Eighteen male SD rats were randomly divided into normal group (Ctrl), model group (DOCA/Salt), and DOCA/Salt with hesperidin group (DOCA/Salt + HES). HES was administered for four weeks. Blood pressure, serum creatinine and blood urea nitrogen were measured. The pathological changes in heart and kidney were examined by HE, Masson and Sirius red staining. The expression of α-SMA, collagen I and TGF-β were detected by Western blot. The mRNA levels of Nlrp3, TNF-α, IL-1β, IL-6 and NOXs were measured using qRT-PCR. Results Compared with the model group, HES administration significantly attenuated the occurrence of DOCA/Salt hypertension, improved renal function indicators of hypertensive rats, reduced renal and cardiac fibrosis, deduced the expression of α-SMA, collagen I and TGF-β, inhibited the expression of Nlrp3, TNF-α, IL-1β and IL-6, and decreased the expression of NOXs in renal and cardiac tissues. Conclusions HES can delay the occurrence of hypertension and protect against hypertension-induced renal and cardiac tissue damage, which may be related to the reduction of inflammatory reaction and oxidative stress by HES.
RESUMEN
Trichloroethylene (TCE) is a common industrial organic solvent and environmental contaminant. People are exposed to TCE through occupational contact or environmental pollution, which leads to serious human health hazards. A large number of studies have shown that oxidative stress plays an important role in the TCE-induced multi-target organ toxicity. However, the research of related signaling pathways remains to be deepened. In this review, we summarized the epidemiological, animal, and cellular studies correlated to liver toxicity, kidney toxicity, cardiac developmental toxicity, placental developmental toxicity, neurodevelopmental toxicity, and autoimmune response induced by TCE. In addition, the possible molecular mechanisms of oxidative stress in TCE-induced toxicity were concluded, including DNA damage, mitochondrial dysfunction, cell apoptosis, and abnormal activation of the immune system. Through literature review, we proposed that nuclear factor E2 related factor 2 may play an important role in mediating TCE-induced target organ toxicity, providing a theoretical basis for the prevention and treatment of adverse health effects caused by TCE.
RESUMEN
Background: Urinary albumin excretion has been purported to be strongly linked to cardiovascular events in hypertensive patients. The prevalence of microalbuminuria in patients with essential hypertension and its relationship with target organ damage was evaluated with the present study, as the correlation of microalbuminuria and target organ damage except cardiovascular events has not been deliberated upon much in the past.Methods: One hundred and twenty cases of essential hypertension were enrolled sequentially. Prevalence of urinary albumin excretion and its correlation with target organ damage (left ventricular hypertrophy, retinopathy and stroke) was analyzed. Urinary albumin excretion was assessed by turbidimetry method, while microalbuminuria was calculated by urine albumin to creatinine ratio.Results: Microalbuminuria was observed in 57.7% cases of essential hypertension. Target organ damage was observed in 62.5% (75) patients, out of which 78.66% patients had associated microalbuminuria (p<0.05). Higher prevalence was observed in patients with longer duration and greater severity of hypertension, increased body mass index and dyslipidemia.Conclusions: The assessment of microalbuminuria in hypertensive patients is a great value addition for the evaluation of target organ damage. Prompt control of hypertension and lipid levels along with weight management may lead to decreased risk of microalbuminuria.
RESUMEN
OBJECTIVE: To investigate the chronic toxicity and carcinogenicity of kresoxim-methyl in rats. METHODS: Specific pathogen free SD rats were randomly divided into control group and low-, medium-and high-dose groups according to the body weight of rats, 120 rats in each group with half male and half female rats. The chronic toxicity and carcinogenesis was induced in rats for 104 weeks by oral feeding. The dose of kresoxim-methyl in feed of male and female rats was 0, 75, 300 and 1 200 mg/kg. During the process of experiment, the body weight of rats was weighed. The blood biochemistry, organ coefficient and histopathology were examined at the end of the exposure, and the tumor incidence was calculated. RESULTS: There was no significant difference in mortality of the female or male rats in the four groups(P>0.05). At the 32 nd, 48 th and 56 th week after exposure, the body mass of female rats in the high dose group was lower than that in control group(P<0.05); at the 8 th, 16 th, 24 th and 32 nd week, the body mass of male rats in the high dose group was lower than that in the control group(P<0.05). The organ coefficients of heart and adrenal gland of female rats in the high dose group were higher than those in the control group and the low dose group(P<0.05). The organ coefficient of liver of male rats in the high dose group was lower than that in the control group(P<0.05). The alkaline phosphatase of male rats in the three dose groups was lower than that in the control group(P<0.05). The blood glucose of male rats in the high dose group was higher than that in the control group(P<0.05). The aspartate aminotransferase of male rats in the high dose group was lower than that in the control group(P<0.05). There was no significant difference among the three indexes in female rats(P>0.05). The tumor incidence of the control group and the low, medium and high dose groups were 68.3%, 75.0%, 75.0% and 78.8%, respectively, with no significant difference(P>0.05). The tumor incidence of the female rats was higher than that of the male rats(87.0% vs 61.5%,P<0.01).The tumor multiplicity of the above four groups were 38.3%, 35.8%, 35.0%, 39.8%, respectively, with no significant difference(P>0.05). The tumor multiplicity in female rats was higher than that in male rats(56.9% vs 17.6%,P<0.01). CONCLUSION: The no observed adverse effect level of kresoxim-methyl to female and male SD rats was 24.726 and 20.002 mg/(kg·d), respectively. No carcinogenicity of kresoxim-methyl to SD rats was observed.

Resumen: La hipertensión arterial (HTA) en niños y adolescentes es una importante patología, de reservado pronóstico, asociada a factores modificables y no modificables. La prevalencia estimada es de apro ximadamente un 3,5%, la cual va aumentando progresivamente con la edad. El método ideal para su diagnóstico es la medición de la presión arterial (PA) con instrumentos auscultatorios. De acuerdo a la Academia Americana de Pediatría (AAP) la PA debe ser medida en niños mayores de 3 años una vez al año, y en niños menores de 3 años, si presentan factores de riesgo. Una vez confirmada la HTA, la evaluación debe dirigirse hacia la detección de una enfermedad causal y/o a la búsqueda de factores de riesgo asociados a una HTA primaria. El objetivo del tratamiento de la HTA primaria y secundaria en pediatría es lograr un nivel de PA que disminuya el riesgo de daño de los órganos blanco. Las opciones terapéuticas incluyen: tratamiento según etiología específica, no farmacológico y farmacológico. En esta Guia se presenta la posición de la Rama de Nefrología de la Sociedad Chile na de Pediatría con el objetivo de orientar a pediatras y nefrólogos infantiles en correcto manejo de la HTA en la infancia. En esta segunda parte se presentan las recomendaciones sobre el tratamiento antihipertensivo, haciendo énfasis en los cambios de estilo de vida.
Abstract: Hypertension (HTN) in children and adolescents is an important pathology, of, guarded prognosis, associated with modifiable and non-modifiable factors. The estimated prevalence is around 3.5% which increases progressively with age. The ideal method for its diagnosis is the measurement of blood pressure (BP) with auscultatory instruments. According to the American Academy of Pedia trics (AAP), BP should be measured in children older than three years of age once a year, and in children younger than three years of age if they present risk factors. Once the HTN is confirmed, the evaluation should be directed towards the detection of a causative disease and/or the search for risk factors associated with a primary HTN. The objective of treating primary and secondary HTN in pediatrics is to achieve a BP level that decreases the risk of target organ damage. Therapeutic op tions include treatment according to specific etiology, non-pharmacological and pharmacological one. This paper presents the position of the Chilean Society of Pediatrics Nephrology Branch with the aim of guiding pediatricians and pediatric nephrologists in the correct management of HTN in childhood. In this second part, recommendations on antihypertensive treatment are presented with an emphasis on lifestyle changes.

The mortality rate from cardiovascular disease (CVD) in India is higher than the global figures (272 per 100,000 persons vs. 235 per 100,000 persons, respectively). Smoking, obesity, hypertension, diabetes and dyslipidemia are the known risk factors for atherosclerotic cardiovascular disease (ASCVD). The treatment of either condition aims to reduce the risk of ASCVD. This goal is achievable only when a holistic, simultaneous treatment is initiated and is monitored to reduce the blood glucose, blood cholesterol, and BP. India heralds a huge population of nearly 73 million people with diabetes. Diabetes is one of the major contributors of ASCVD, dyslipidemia and hypertension often coexist with diabetes. Patients diagnosed with either condition need risk stratification, followed by defining the treatment target for each risk category and developing appropriate treatment strategies based on the risk category. Unfortunately, there is no clear guideline that defines the treatment targets and subsequent management. This statement has been created based on the vast experience and an extensive literature review conducted by experts from multidisciplinary teams to address several treatment dilemmas that are routinely faced by clinicians when treating their patients with diabetes. An attempt is made to provide well-defined answers to these quandaries. This statement discusses screening, diagnosis, risk stratification, treatment targets, and management of dyslipidemia and/or hypertension in patients with diabetes and provides a roadmap for the treatment of Indian patients to curtail the risk of ASCVD.
RESUMEN
Childhood obesity has been an important public health issue worldwide. We searched PubMed, CNKI, and Wanfang databases to perform a systematic review of how to identify early target organ (including heart, vessel, kidney and liver etc) damage in children, the effects of obesity on early target organ damage (including left ventricular hypertrophy, left ventricular diastolic dysfunction, increased carotid intima-media thickness, increased arterial stiffness, impaired glomerular filtration rate, and non-alcoholic fatty liver disease, etc), the possible biological mechanisms (including hemodynamic changes, abnormal metabolic indices, and effects of cytokines and inflammatory factors, etc), and the effects of exercise training and dietary interventions on target organ damage in obese children. Thus, it is important to take effective measures to prevent and control childhood obesity, and finally to reduce the prevalence of target organ damage.
RESUMEN
Objective@#To evaluate the non-carcinogenic health risk of heavy metals (As, Cd, Cr, Cu, Mn, Pb and Zn) in residential indoor dust for young children around an e-waste dismantling area in South China.@*Methods@#A village around an e-waste dismantling area in South China was selected as a research site in October 2016. Convenience sampling method was used to select 36 houses in the village and 36 dust samples were collected by vacuum cleaner. The concentrations of heavy metals (Cd, Cr, Cu, Mn, Pb and Zn) in each sample were determined and expressed by the average value. Non-carcinogenic health risk assessment was conducted using the US Environmental Protection Agency (EPA) Health Risk Assessment (HRA) model, the American Toxicology and Disease Registry (ATSDR) Target-organ Toxicity Dose (TTD) approach and the ATSDR Binary Weight-of-Evidence (BINWOE) model.@*Results@#The mean ± SD of concentrations of As, Cd, Cr, Cu, Mn, Pb and Zn were (48.90±33.91), (5.95±3.89), (173.57±580.37), (412.71±1 190.00), (612.82±540.70), (297.41±293.22) and (1 052.81±1 156.48) mg/kg, respectively. The HI value of TTD (2.670) and BINWOE (2.933) were higher than the safety threshold of EPA recommended non-carcinogenic health risk. The HI value of TTD and BINWOE were 1.93 and 2.12 times higher than the HI value of HRA (1.386).@*Conclusion@#There was non-carcinogenic health risk of heavy metals (As, Cd, Cr, Cu, Mn, Pb and Zn) via residential indoor dust around the e-waste dismantling area for local children.
RESUMEN
The segmental neuronal connection plays an important role in acupoint-target organ specific correlation. The acupoint-target organ correlation includes acupoint-visceral correlation and acupoint-somatic correlation. The acupoint-viscera correlation involves both the primary central (spinal cord) mechanism and the peripheral (dorsal root ganglion, DRG) mechanism implemented by segmental nerve reflex via the spinal cord and axonal reflex via DRG respectively, while the acupoint-somatic correlation mainly involves the axonal reflex.
RESUMEN
Objective: To investigate the effects of allicin (All) in combination with lycopene (Lyc) against target organ damage and oxidative stress induced by hypertension in spontaneously hypertensive rats (SHRs). Methods: SHRs aged 10 weeks were randomly divided into four groups (n=8 in each group): SHR, SHR+All, SHR+Lyc, and SHR+All+Lyc. SHR in SHR+All, SHR+Lyc and SHR+All+Lyc groups were intraperitoneally or intragastrically administered with 15 or 7.5 mg/(kg•d) of All and Lyc at the same time daily for 6 weeks. Male WKY rats were intraperitoneally injected with the same volume of normal saline and served as normotensive controls (WKY group). Six weeks later, histopathological changes of thoracic aorta and kindeys were evaluated by HE staining and according to Paller's method. The indexes of oxidation (MDA) and antioxidants (SOD, CAT and GSH) in serum or thoracic aorta were determined by enzyme-linked immunosorbent assay (ELISA). Production of intracellular superoxide anion was stained by dihydroethidium (DHE) staining and detected using laser scanning confocal microscope. Results: SHR+Lyc+All group significantly ameliorated arterial wall thickening and inflammatory injury of the kindey in SHR compared with SHR+All group and SHR+Lyc group. Administration of All combined with Lyc significantly increased activities of antioxidative enzymes (SOD and GSH) and the content of CAT in aortas when compared with those of SHR and SHR receiving All or Lyc administration alone (P<0.05). In addition, the combined treatment of All with Lyc also significantly reduced the contents of MDA and O2- of SHR compared to SHR (P<0.05). Conclusion: This combination of All and Lyc can reduce target organ damage and level of oxidative stress induced by hypertension, which may be attributed to their regulations on ROS level, antioxidant and anti-inflammatory abilities.
RESUMEN
Diabetes mellitus (DM) is a metabolic disease characterized by hyperglycemia, with a high incidence and many complications. It has become an increasingly serious public health problem in the world, and has seriously affected the quality of life. Phosphatidylinositol-3-kinases (PI3K)/protein kinase B (Akt) signaling pathway is the main pathway of insulin signal transmission and the main signal channel for regulating blood glucose. The abnormal signal molecule of PI3K/Akt may cause abnormal signal transduction pathway, so as to impact the proliferation, apoptosis, metastasis and invasion of the corresponding tissues and organs, and lead to the occurrence of disease. Study of PI3K/Akt signal channel has a positive significance for investigating whether traditional Chinese medicine(TCM) has a definite and stable hypoglycemic effect. Currently, there are many TCM and Western medicines to treat diabetes, however, most drugs, especially Western medicines, have a relatively poor effect in controlling complications. To understand the progress of TCM in treatment of diabetes, in expectation of better studying the comprehensive therapeutic effect and mechanism of TCM on diabetes, and further developing the multi-target, multi-way and multi-channel advantages and features of TCM in the treatment of diabetes, this paper focuses on a systematic analysis on the progress of in vivo and in vitro studies on DM based on PI3K/Akt signaling channel in recent years, including the effect of the signaling channel on insulin secretion, the three main target organs of insulin (liver, skeletal muscle and fat), and its effect on the four main complications of diabetes (brain, kidney, heart, testis), and also provides certain ideas and guidance for the study of hypoglycemic mechanism of TCM monomer, TCM and compound medicine.
RESUMEN
Background: Critical amount of urinary albumin excretion has long been reported to be one strong predictor of cardiovascular events in hypertensive patients. Very few studies have been conducted till now depicting correlation of microalbuminuria and target organ damage in patients with essential hypertension, except cardiovascular events. We evaluated the prevalence of microalbuminuria in patients with essential hypertension and its relationship with target organ damage.Methods: Total 120 patients of essential hypertension were studied. Prevalence of urinary albumin excretion and its correlation to target organ damage (left ventricular hypertrophy, retinopathy and stroke) was analysed. Urinary albumin excretion was assessed by turbidimetry method and microalbuminuria was assessed by urine albumin to creatinine ratio.Results: Microalbuminuria was found to be present in 57.7% patients. Target organ damage was observed in 62.5% (75) patients, out of which 78.66% patients had associated microalbuminuria (p <0.05). Amongst them, higher prevalence was observed in patients with longer duration and greater severity of hypertension, increased body mass index and dyslipidemia.Conclusions: Microalbuminuria assessment in hypertensive patients is an important test for the evaluation of target organ damage. Optimal management of hypertension, weight control, and maintenance of normal lipid levels leads to decreased risk of microalbuminuria.
RESUMEN
Objective To investigate the target organs function damage in elderly patients with H type hypertension and its association with blood pressure variability.Methods Ninety-two patients with H type hypertension in the Affiliated Hospital of Inner Mongolia Medical University from January 2014 to January 2016 were collected as the observation group and contemporaneous 135 elderly patients with non-H type hypertension were collected as the control group.The main observation indicators included 24 h systolic/diastolic blood pressure variability,24 h average systolic/diastolic blood pressure,glomerular filtration rate(GFR),serum creatinine,24 h urinary microalbumin,carotid intima-media thickness and left ventricular mass index.Results Compared with the control group,24 h systolic blood pressure variability,24 h diastolic blood pressure variability,creatinine,24 h urinary microalbumin,carotid intima-media thickness and left ventricular mass index in the observation group were significantly increased(P＜0.05);GFR was significantly decreased (P＜0.05).The multiple linear regression analysis showed that 24 h systolic blood pressure variability was the factors affecting GFR (P＜0.05);24 h systolic blood pressure variability was the factor affecting~the creatinine level (P＜0.05);24 h systolic blood pressure,24 h systolic blood pressure variability and 24 h diastolic blood pressure variability were the influence factors of carotid intima-media thickness (P＜0.05);24 h systolic blood pressure variability was the influence factor of left ventricular mass index (P＜0.05).Conclusion The target organs function damage in the patients with H type hypertension is serious,and the blood pressurevariability enlargement is the influencing factor of target organs function damage.
RESUMEN
Prehypertension is an independent risk factor for end stage of heart, brain and renal diseases. The immune inflammatory imbalance promotes the occurrence of damage of target organs in the pre-hypertension stage. This article focuses on the relationship between the immune-inflammation and prehypertension and its target organ damage. It was found that acupuncture treatment can lower blood pressure, postpone the development of prehypertension, improve vascular endothelia function and immune function, down-regulate the levels of serum proinflammatory cytokines, and reduce inflammatory reactions of the heart and kidney, possible by way of regulating cellular signal pathways as TLR 4/NF-κB, p 38/MAPK, CaM-eNOS-NO, TGF-β 1/Smads, etc. and playing a protective effect on the target organs. However, its detailed mechanisms remain largely unknown up to now.
