The antiplasmodial activity of the carboxylic acid metabolite of piperaquine and its pharmacokinetic profiles in healthy volunteers.

The long-acting antimalarial drug piperaquine can be metabolized into the carboxylic acid metabolite (PQM). However, the clinical relevance of PQM remains unclear. The pharmacodynamics/pharmacokinetics of PQM were studied. The antimalarial activity of PQM was studied in vitro (Plasmodium strains Pf3D7 and PfDd2) and in vivo (murine Plasmodium yoelii). The toxicity of PQM was evaluated in mice, in terms of the general measures of animal well-being, serum biochemical examination and ECG monitoring. The pharmacokinetic profiles of piperaquine and its metabolite PQM were investigated in healthy subjects after recommended oral doses of piperaquine. PQM showed no relevant in vitro antimalarial activity (IC50 > 1.0 μM) with no significant toxicity. After recommended oral administration of piperaquine to healthy subjects, the maximum concentration of PQM was less than 30.0 nM, and it did not accumulate after repeated dosing. With a low antimalarial potency, PQM should not contribute to the efficacy of piperaquine with clinically acceptable doses.

Comparison of hematologic and serum biochemical variables in Brucella-infected and Brucella-free adult Himalayan marmots (Marmota himalayana).

The Himalayan marmot (Marmota himalayana) plays a reservoir role in the epidemiology of brucellosis. However, the changes in blood biochemical parameters are still unclear in Brucella-seropositive marmots. The present study was designed to explore the hematologic and biochemical variable changes in Brucella-seropositive marmots. Blood samples were collected from the dorsalis pedis vein of Himalayan marmots (24 Brucella-seropositive marmots and 24 Brucella-free marmots). Ten hematologic and 10 serum biochemical variable examinations were performed and analyzed. Our results showed that leukocyte, platelet, neutrophil, and lymphocyte counts significantly increased, while the level of carbon dioxide combining power decreased in Brucella-infected marmots. These findings indicate that Brucella triggers an immune response in Himalayan marmots. This study provides a preliminary investigation of the changes in blood biochemical analytes in Brucella-infected marmots. The interaction between Brucella infection and blood biochemical indices in Himalayan marmots should be further explored.

Reduced myocardial work in asymptomatic heavy alcohol use and its correlation with epicardial adipose tissue volume and serum biomarkers.

It is unclear whether long-term heavy alcohol use leads to early cardiac function decline. Long-term heavy alcohol use developed reduced cardiac function in subclinical status by analyzing myocardial work (MW). Epicardial adipose tissue (EAT) volume and serum biomarkers contribute to identify potential factors sensitive in predicting early cardiac function decline. We enrolled 31 asymptomatic participants with heavy alcohol use and 33 age and sex-matching nondrinking individuals. Participants underwent echocardiography, MW analysis, EAT volume measurement, serum biochemical examinations, and body composition assessment. We used multivariate linear regression to identify correlation between MW and total cholesterol (TC), EAT volume, and placental growth factor (PlGF). To determine global work efficiency (GWE) below the normal reference value of 96%, we developed receiver operating curves with area under curve (AUC) to compare different combinations of TC, EAT volume, and PlGF. All 64 participants were male. GWE was reduced in the alcohol use group compared with the control group (96, interquartile range [IQR] = [95-97.75] vs. 97, IQR = [97-98], p = .004). TC was positively associated with GWE (β = .434, 95% confidence interval [CI] = 0.228 to 1.328, p = .008), whereas EAT volume (β = -.398, 95% CI = -0.000446 to -0.000093, p = .005) and PlGF (β = -.493, 95% CI = -1.010 to -0.230, p = .004) were inversely associated with GWE. The most significant AUC for reduced GWE was TC + EAT volume (0.851, 95% CI = 0.671 to 1, p = .006). Asymptomatic heavy alcohol use has shown early reduced cardiac function which can be associated with altered fat metabolism, suggesting individuals with alcohol use and abnormal fat metabolism need to be alert to heart damage.

Effect of the Composition of Leuzea and Cranberry Meal Extracts on Metabolic Processes in Norm and Pathology.

This study was conducted to evaluate the effects of long-term administration of a new herbal composition of leuzea and cranberry meal extracts at a dose of 70:500 mg/kg in healthy and pathological mice. After 4 weeks of daily composition administration to healthy CD-1 mice and C57BL/6 mice with diet-induced metabolic syndrome, oral glucose tolerance test (OGTT), serum biochemical examination and histology of internal organs were performed. Additionally, histological examination of white and brown adipose tissue was performed to evaluate the ability of the composition to prevent abdominal obesity in C57BL/6Ay (agouti yellow) mice. The results showed that the composition increased tissue sensitivity to glucose in healthy CD-1 mice; at the same time, it did not worsen the course of pathological processes in pathological mice. In both cases, the application of the developed composition was safe and contributed to the restoration of metabolic parameters.

Anti-triple-negative breast cancer metastasis efficacy and molecular mechanism of the STING agonist for innate immune pathway

Background With high recurrence and metastatic rates, triple-negative breast cancer (TNBC) has few therapy choices. The innate immune stimulator of interferon genes protein (STING) pathway has emerged as a critical foundation for improving anticancer immunotherapy. Although 2’,3’-cGAMP has been shown to have therapeutic potential as a STING agonist in subcutaneous solid tumour treatments in mice, the effect of cGAMP in metastatic malignancies has received less attention. Methods Bioluminescence imaging technology was applied to monitor TNBC tumour cell metastasis in living mice. Serum biochemical test and blood routine examination of mice were used to demonstrate cGAMP administration had no toxicity. The activation of DCs and CD8+ T cells was demonstrated by flow cytometry. The pharmacological mechanism of cGAMP for suppressing breast tumour metastasis was also explored. Results cGAMP treatment substantially suppressed tumour development and metastasis without adverse effects. cGAMP activated the cGAS-STING-IRF3 pathway, which modified the tumour immune milieu to reverse the Epithelial-Mesenchymal Transition (EMT) and PI3K/AKT pathways and prevent tumour metastasis. It was postulated and proven that cGAMP had a pharmacological mechanism for reducing breast tumour metastasis. Conclusion The findings suggest that cGAMP could be useful in the immunotherapy of immune-insensitive metastatic breast cancer.

Urea Transporter Inhibitor 25a Reduces Ascites in Cirrhotic Rats

Ascites is a typical symptom of liver cirrhosis that is caused by a variety of liver diseases. Ascites severely affects the life quality of patients and needs long-term treatment. 25a is a specific urea transporter inhibitor with a diuretic effect that does not disturb the electrolyte balance. In this study, we aimed to determine the therapeutic effect of 25a on ascites with a dimethylnitrosamine (DMN)-induced cirrhotic rat model. It was found that 100 mg/kg of 25a significantly increased the daily urine output by 60% to 97% and reduced the daily abdominal circumference change by 220% to 260% in cirrhotic rats with a water intake limitation. The 25a treatment kept the serum electrolyte levels within normal ranges in cirrhotic rats. The H&E and Masson staining of liver tissue showed that 25a did not change the cirrhotic degree. A serum biochemical examination showed that 25a did not improve the liver function in cirrhotic rats. A Western blot analysis showed that 25a did not change the expression of fibrosis-related marker protein α-SMA, but significantly decreased the expressions of type I collagen in the liver of cirrhotic rats, indicating that 25a did not reverse cirrhosis, but could slow the cirrhotic progression. These data indicated that 25a significantly reduced ascites via diuresis without an electrolyte imbalance in cirrhotic rats. Our study provides a proof of concept that urea transporter inhibitors might be developed as novel diuretics to treat cirrhotic ascites.

Treatment effects of phosphorylated Chrysanthemum indicum polysaccharides on duck viral hepatitis by protecting mitochondrial function from oxidative damage

To define the underlying mechanism of the beneficial role of Chrysanthemum indicum polysaccharides (CIPS) and phosphorylated Chrysanthemum indicum polysaccharides (pCIPS) in duck viral hepatitis (DVH), we evaluated the protective effects of the CIPS and pCIPS against DVH in terms of antioxidation and mitochondrial function. Fluorescence probes and several assay kits were used to determine the oxidative stress and mitochondrial dysfunction in vitro and vivo. Additionally, transmission electron microscopy was applied to observe the changes of mitochondrial ultrastructure in the liver tissue. Our results indicate that the CIPS and pCIPS significantly enhanced the survival of duck hepatitis A virus type 1 (DHAV-1) infected ducklings. Moreover, the CIPS and pCIPS suppressed oxidative stress and preserved mitochondrial function, such as enhanced antioxidant enzyme activity, increased ATP production, and stabilized mitochondrial membrane potential (MMP). Meanwhile, the results of hematoxylin-eosin (HE) staining and serum biochemical examination demonstrated that treatment with the CIPS and pCIPS could decrease focal necrosis and infiltration of inflammatory cells, which in turn reducing liver injury. Furthermore, the CIPS and pCIPS were able to preserve liver mitochondrial membrane integrity in DHAV-1 challenged ducklings. Notably, the pCIPS was significantly outperformed the CIPS on all measures of liver and mitochondrial function. These results suggested that mitochondrial homeostasis plays an important role in alleviating oxidative damage in the livers, and the hepatocyte protective effects of the CIPS were enhanced after phosphorylation modification.

Rosmarinic acid alleviates acetaminophen-induced hepatotoxicity by targeting Nrf2 and NEK7-NLRP3 signaling pathway

Rosmarinic acid (RA) is a natural polyphenol with various biological activities, such as anti-oxidative, anti-fibrotic, and hepatoprotective properties. The objective of this study was to investigate the protective effect of RA against acetaminophen (APAP)-induced hepatotoxicity (AILI) and explore the underlying mechanisms. Kunming mice were treated with RA (20, 40, or 80 mg/kg, i.g) for 7d, followed by an intraperitoneal injection of APAP (500 mg/kg). The liver injury was evaluated by serum biochemical and liver histopathological examinations. Human HepG2 cells were pre-treated with RA (20, 40, or 80 μmol/L) and then incubated with APAP (25 mmol/L) for 24 h. The MTT assay, wound healing assay, transwell migration assay, flow cytometry, and western blotting were employed to further evaluate RA’s protective effects on AILI and explore the mechanisms. The results indicated that RA pre-treatment lowered the serum ALT and AST levels, ameliorated the histological damage to the liver, and reduced ROS generation and the production of IL-1β and IL-18 in the liver tissues in APAP-treated mice. Moreover, pre-treatment with RA could promote the cell viability and migration ability and inhibit apoptosis in APAP-treated HepG2 cells. Mechanistically, RA could significantly suppress the APAP-induced activation of the NEK7-NLRP3 signaling pathway. Notably, depletion of Nrf2 by short hairpin RNA (shRNA) partly eliminated the protective effects of RA on AILI and the suppression of NEK7-NLRP3 signaling by RA. In summary, these results indicate that RA has a protective role against AILI through Nrf2-mediated inhibition of ROS production and suppression of the NEK7-NLRP3 pathway.

​​Evaluation of Hematological and Serum Biochemical Alterations in Dogs Affected with Congestive Heart Failure

Background: Congestive heart failure (CHF) is common disorder of dogs that occur most frequently as a result of Dilated Cardiomyopathy (DCM), Degenerative Mitral Valve Disease and pericardial diseases. An early diagnosis can be carried out through the use of specific diagnostic techniques such as x-rays, echocardiography etc. The goal of this study was to see if dogs with CHF go through any substantial alterations in their hematology or serum biochemistry. Methods: The current investigation was conducted during the period April, 2020 to April 2021 at Veterinary Clinical Complex, Khanapara, Assam. Thirty four (n=34) dogs with CHF confirmed by echocardiography and eight (n=8) healthy dogs were considered for the study. Blood samples from all selected dogs were subjected to routine hematological and serum biochemical examination. Result: The hematological assessment revealed no significant alterations. During the course of the study, there were significant alterations in the serum biochemical parameters viz. LDH, BUN, creatinine, AST, ALT, total serum protein, albumin and albumin: globulin ratio. Findings of the study revealed that hematology and biochemistry were more useful in ruling out CHF or in identifying concurrent diseases than diagnosing CHF itself.

The improvement of nonalcoholic steatohepatitis by Poria cocos polysaccharides associated with gut microbiota and NF-κB/CCL3/CCR1 axis

BackgroundNonalcoholic steatohepatitis (NASH) has been linked to inflammation induced by intestinal microbiota. Poria cocos polysaccharides (PCP) possesses anti-inflammation and immunomodulation functions; however, its preventive effects against NASH and potential mechanisms need to be explored. MethodsThe composition of PCP was determined using ion chromatography. C57BL/6 mice were administered the methionine and choline deficient (MCD) diet for 4 weeks to establish the NASH model or methionine-choline-sufficient (MCS) diet to serve as the control. Mice were assigned to the MCS group, MCD group, low-dose PCP (LP) group, and high-dose PCP (HP) group, and were administered the corresponding medications via gavage. Serum biochemical index analysis and liver histopathology examination were performed to verify the successful establishment of NASH model and to evaluate the efficacy of PCP. The composition of intestinal bacteria was profiled through 16S rRNA gene sequencing. Hepatic RNA sequencing (RNA-Seq) was performed to explore the potential mechanisms, which were further confirmed using qPCR, western blot, and immunohistochemistry. ResultsPCP consists of glucose, galactose, mannose, D-glucosamine hydrochloride, xylose, arabinose, and fucose. PCP could significantly alleviate symptoms of NASH, including histological liver damage, impaired hepatic function, and increased oxidative stress. Meanwhile, HP could reshape the composition of intestinal bacteria by significantly increasing the relative abundance of Faecalibaculum and decreasing the level of endotoxin load derived from gut bacteria. PCP could also downregulate the expression of pathways associated with immunity and inflammation, including the chemokine signaling pathway, Toll-like receptor signaling pathway, and NF-kappa B signaling pathway. The expression levels of CCL3 and CCR1 (involved in the chemokine signaling pathway), Tlr4, Cd11b, and NF-κb (involved in the NF-kappa B signaling pathway), and Tnf-α (involved in the TNF signaling pathway) were significantly reduced in the HP group compared to the MCD group. ConclusionsPCP could prevent the development of NASH, which may be associated with the modulation of intestinal microbiota and the downregulation of the NF-κB/CCL3/CCR1 axis.

A randomized, placebo-controlled, double-blind trial to evaluate efficacy and safety of Shen-Yuan-Dan capsules, a traditional Chinese medicine, for treatment of peri-procedure myocardial injury following percutaneous coronary intervention

BackgroundPeri-procedural myocardial injury (PMI) is a common complication of percutaneous coronary intervention (PCI), which cannot be entirely avoided using available treatments. The findings of earlier research have shown that Shen-Yuan-Dan (SYD) capsules, a traditional Chinese medicine, can potentially alleviating PMI. This study aimed to confirm further this hypothesis in a rigorous, well-designed randomized controlled study. MethodsOur clinical trial was randomized, double-blinded, and placebo-controlled. A total of 181 patients with unstable angina (UA) undergoing elective PCI were randomized to pretreatment with SYD or a placebo under the basis of conventional treatment; 87 patients were pretreated with SYD (4 capsules, 3 times a day, with a further 4 capsules 2 h before PCI) 3 days before the procedure, and 94 patients were given a placebo. No patients received reloading statins before PCI, and SYD or placebo was maintained for 1 month after PCI. The primary endpoint was the incidence of PMI. The secondary endpoint was calculating the incidence rate of all 30-day major adverse cardiovascular events (all-cause mortality, non-fatal myocardial infarction, unplanned revascularization). The safety outcomes, including abnormalities in electrocardiogram and serum biochemical examinations caused by drug use, were also tested. ResultsThe levels of creatine kinase-myocardial band (CK-MB) in both the SYD and placebo groups were increased at 4 h and 24 h after PCI compared with before the procedure (P < 0.05). The incidence rate of PMI in the SYD group (10.3 %) was lower than that in the placebo group (34 %) (absolute difference, 23.7 % [95 % CI, 11.7–34.8 %], P < 0.01). After taking SYD, the relative risk reduction (RRR) and absolute risk reduction (ARR) were 69.7 % and 24.3 %, respectively; further, number needed to treat (NNT) was 4.2. The 30-day major adverse cardiovascular event (MACE) rate was not statistically different between the SYD and placebo groups (6.9 % vs. 9.6 %, P = 0.352). There were no abnormal situations during the trial. ConclusionThese findings showed that pretreatment with SYD could safely reduce the incidence rate of PMI in patients with UA undergoing elective PCI. Further study on the effects of SYD and how it can improve adverse cardiovascular events outcomes is needed.

In vivo Antioxidant Related Effect of Orally Administered Aqueous Extract of Saliva triloba in Human Volunteers

Saliva triloba, belongs to the Lamiaceae family, is one in all the vital medicinal plant species. This work aims to study the antioxidant-related effects of trilobite saliva in the human body through in vivo studies and the effects on liver, kidney, and heart function tests. For five days, nine healthy participants consumed 250 mL of trilobite saliva extract orally. On the fifth day, blood samples were taken one hour before and after the first dosage of water extract (samples I and II, respectively), and again one day after the last dose (ie, day 6, sample III). Before the first dosage, the first blood sample was taken (ie sample I) was used as a control for the subsequent II and III samples. Subsequent determinations were performed: serum total antioxidant status (TAS), red blood cell reduced glutathione (GSH), red blood cell superoxide dismutation (SOD) A activity, malondialdehyde (MDA), and serum-selected biochemical tests. After 5 days of oral administration of trilobite saliva extract in healthy volunteers, serum TAS, erythrocyte GSH and erythrocyte SOD activity were significantly increased, and had no influence on serum biochemical examinations of kidney, liver, heart, pancreas, etc., contrasted with zero-time management. In Conclusion, salivary clover extract has effective anti-oxidation related effects in vivo. Because these findings were obtained in healthy people without oxidative stress, it means that clover saliva will enhance the bottom line of the defense system against probable oxidative stress while having no adverse effects, decreasing or avoiding pathological diseases associated with oxidative stress

Ameliorative effect of ethanolic extract of Limnophila rugosa (Scrophulariaceae) in paracetamol- and carbon tetrachloride-induced hepatotoxicity in rats

BackgroundLimnophila rugosa (Scrophulariaceae) is a perennial aquatic plant used as a diuretic and digestive tonic as well as in the treatment of diarrhea, dysentery, dyspepsia and urinary ailments. Genus Limnophila has been reported as hepatoprotective. The present study was undertaken to evaluate the hepatoprotective activity of the ethanolic extract of L. rugosa aerial part in paracetamol- and carbon tetrachloride-induced (CCl4) hepatotoxicity in albino Wistar rats. Ethanolic extract was subjected to high-performance liquid chromatography (HPLC) analysis for the estimation of phenolic and flavonoid compounds and gas chromatography–mass spectrometry (GC–MS) analysis for phytochemical analysis. The in vitro antioxidant activity was carried out by 2,2-diphenyl-1-picrylhydrazyl, nitric oxide radical and hydrogen peroxide assay. Hepatoprotective potential of L. rugosa was studied in paracetamol (750 mg/mg)- and CCl4 (1.25 ml/kg)-induced liver damage in albino rats at dose 200 and 300 mg/kg using silymarin (100 mg/kg) as standard. Lipid peroxidation, superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) were determined in liver tissue homogenate. Serum biochemical and histopathological examination was performed. Molecular docking analysis was performed to understand the molecular mechanism of hepatoprotective activity.ResultsHPLC analysis revealed predominance of rutin. GC–MS analysis revealed camphor as principal component. Ethanolic extract exhibited significant concentration-dependent scavenging efficacy. The altered biochemical chemical parameters: aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, bilirubin, cholesterol, albumin, globulin and total protein, were significantly improved at 200 and 300 mg/kg in experimental rats. Extract signified hepatoprotective by decreasing lipid peroxidation and upregulating SOD, CAT and GSH. The findings were well supported by histological analysis. 2-Butyl-2, 7-octadien-1-ol (-5.8) and camphor (-4.8) gave the highest docking score on the transforming growth factor-β1.ConclusionsThe ameliorative effect of L. rugosa in the rat model of hepatotoxicity could be attributed to its antioxidant potential and bioactive principles such as betulin, 5-hydroxy-6,7,4′-trimethoxyflavone (salvigenin), betulinic acid, ursolic acid, 3-octanol, acetophenone, anisylacetone, caryophyllene, cis-anethole and the compounds camphor and 2-butyl-2,7-octadien-1-ol identified from GC–MS analysis.

Hepatotoxic mechanism of diclofenac sodium on broiler chicken revealed by iTRAQ-based proteomics analysis.

BackgroundAt the therapeutic doses, diclofenac sodium (DFS) has few toxic side effects on mammals. On the other hand, DFS exhibits potent toxicity against birds and the mechanisms remain ambiguous.ObjectivesThis paper was designed to probe the toxicity of DFS exposure on the hepatic proteome of broiler chickens.MethodsTwenty 30-day-old broiler chickens were randomized evenly into two groups (n = 10). DFS was administered orally at 10 mg/kg body weight in group A, while the chickens in group B were perfused with saline as a control. Histopathological observations, serum biochemical examinations, and quantitative real-time polymerase chain reaction were performed to assess the liver injury induced by DFS. Proteomics analysis of the liver samples was conducted using isobaric tags for relative and absolute quantification (iTRAQ) technology.ResultsUltimately, 201 differentially expressed proteins (DEPs) were obtained, of which 47 were up regulated, and 154 were down regulated. The Gene Ontology classification and Kyoto Encyclopedia of Genes and Genomes pathway analysis were conducted to screen target DEPs associated with DFS hepatotoxicity. The regulatory relationships between DEPs and signaling pathways were embodied via a protein-protein interaction network. The results showed that the DEPs enriched in multiple pathways, which might be related to the hepatotoxicity of DFS, were “protein processing in endoplasmic reticulum,” “retinol metabolism,” and “glycine, serine, and threonine metabolism.”ConclusionsThe hepatotoxicity of DFS on broiler chickens might be achieved by inducing the apoptosis of hepatocytes and affecting the metabolism of retinol and purine. The present study could provide molecular insights into the hepatotoxicity of DFS on broiler chickens.

A combined metabolomics and molecular biology approach to reveal hepatic injury and underlying mechanisms after chronic l-lactate exposure in mice

This study aimed to explore whether chronic l-lactate exposure could affect the peripheral tissues of mice and to determine the underlying pathogenesis. Herein, male C57BL/6 mice were divided into control and l-lactate groups. After l-lactate treatment for eight weeks (1 g/kg), metabolic changes in liver, kidney, muscle, and serum samples were determined by 1H nuclear magnetic resonance (1H NMR)-based metabolomics. Additionally, organ function was evaluated by serum biochemical and histopathological examinations. Reactive oxygen species (ROS) levels were measured using dihydroethidium staining; levels of signals involved in lactate metabolism and ROS-related pathways were detected using western blotting or polymerase chain reaction. Apoptosis was detected by TUNEL-fluorescence staining. Metabolomic analysis revealed that l-lactate mice showed decreased levels of glutathione (GSH), taurine, ATP, and increased glucose content, compared to control mice. Furthermore, l-lactate mice presented significantly higher serum levels of alanine aminotransferase and aspartate aminotransferase and increased glycogen content in hepatic tissues, compared to control mice. l-lactate mice also had a greater number of apoptotic nuclei in the livers than controls. Moreover, l-lactate exposure reduced mRNA and protein levels of superoxide dismutase-2 and c-glutamylcysteine ligase, elevated levels of cytochrome P450 2E1 and NADPH oxidase-2, and increased the protein expressions of LDHB, Bax/Bcl-2, cleaved caspase-3, and sirtuin-1 in hepatic tissues. Together, these results indicate that chronic l-lactate exposure increases oxidative stress and apoptosis in hepatocytes via upregulation of Bax/Bcl-2 expression and the consequent mitochondrial cytochrome-C release and caspase-3 activation, which contributes to the pathogenesis of hepatic dysfunction.

Metabolic perturbations and health impact from exposure to a combination of multiple harmful Maillard reaction products on Sprague-Dawley rats

The metabolic perturbations and health impact of the co-accumulation of acrylamide, harmane, and Nε-(carboxymethyl)lysine was investigated via serum biochemical and histopathological examinations as well as metabolomic analysis.

Data Analysis of Nursing Effects in Pediatric Gastroenterology Department under High Content Image Analysis Technology.

Objective Based on the nursing analysis of children aged 0∼3 in the Department of Gastroenterology, from the perspective of nursing methods and nutrition, bird's nest nursing and high-quality nursing methods were used to intervene children to help them improve their gastrointestinal conditions and sleep quality (Su-Jin, 2021). Methods A total of 2465 healthy children under 3 years were selected, with normal action and intelligence and accompanied by their parents. Among them, there were 635 children in the observation group (O group) and 355 children in the reference group (R group) in the bird's nest nursing group, 572 children in the O group and 603 children in the R group in the other high-quality nursing group. The observation group received routine nursing, while the control group received nest nursing and quality nursing. The height growth rate, weight growth rate, brain weight growth rate, blood cell routine, and serum biochemical examination results of infants aged 6 months and 3 years in the O group, image analysis technology is used to analyze and discuss the gastrointestinal imaging examination of children, so as to conduct more detailed and accurate research. Results Through the analysis and comparison of the physiological index data of 6-month-old and 3-year-old infants in the observation group and the reference group, and the satisfaction of parents, it was found that the children's physiological indexes, gastrointestinal digestion, weight gain, and brain weight gain rate through bird's nest care and high-quality care were slightly better than those in the observation group, and the parents' satisfaction was also slightly higher. Conclusion Wei et al. (2020). By creating a comfortable environment and simulating the children's growth environment under the mother's care, it is found that the bird's nest care and high-quality care programs can calm children's emotions, increase children's appetite and digestion, so as to promote children's gastrointestinal digestion and achieve the goal of healthy growth (Wei et al, 2020). Finally, the conclusion is drawn that starting from the needs of children, scientific and correct gastrointestinal care and dietary nutrition should be used to promote the healthy growth of children.

Assessment of haematological and biochemical alterations in recumbent buffaloes

ABSTRACT The present study was undertaken on adult recumbent buffaloes (n = 63), which were clustered into six groups based on the history and tentative diagnosis viz., infectious, metabolic, traumatic, abdominal dysfunction, intoxication, and musculoskeletal and nervine. An additional group of 10 adult healthy control buffaloes was also included in the study. The blood, serum, and faecal samples were collected on zero day to perform haematological, blood smear, serum biochemical, and faecal examination, respectively. Also, the similar samples were collected on 5 days post treatment (DPT) in recovered and control animals. Genomic DNA from individual blood samples was isolated and subjected to conventional polymerase chain reaction (PCR) and quantitative PCR for exploring Trypanosoma evansi and Bovine Herpes Virus-1 infections, respectively. The detailed history of recumbent buffaloes revealed the mean age as 5.53 ± 0.34 years and duration of recumbency as 2.61 ± 0.38 days. Younger animals (3.92 ± 0.31 years) having ~14 hours of recumbency period showed recovery and good prognosis. On comparison of serum biochemical parameters of recovered and non-recovered recumbent animals, Aspartate Aminotransferase (AST), creatinine phosphokinase, phosphorus, sodium, and chloride showed significant difference between them (p < 0.05); thus, indicating their suitability for being prognostic indicators. Out of 63 recumbent animals, 10 (15.87%) showed recovery from recumbency after 5 DPT. The present study recognized the alterations in haemato-biochemical parameters in recumbent buffaloes for the first time.

Demonstrative Experiment on the Favorable Effects of Static Electric Field Treatment on Vitamin D3-Induced Hypercalcemia

Simple SummaryStatic electric field (SEF) treatment by high-voltage alternating current is a traditional complementary medicine in Japan. Although it is believed that the SEF-induced electric current serves to regulate cellular or humoral responses in patients, the mechanism for SEF treatment remains poorly understood. There have been very few experimental reports on the biological action with SEF treatment. The aim of this study was to elucidate the effects of SEF treatment on vitamin D3 (Vit D3)-induced abnormalities in mice. SEF treatment improved the abnormalities in the renal function tests and the imbalance of serum electrolytes. In addition, this treatment remarkably attenuated the Vit D3-induced tissue injuries (severe tissue calcification in the kidneys, hearts, and stomachs). It was likely that the SEF treatment had some favorable effects on the metabolism of calcium. In conclusion, this study provides important evidence that SEF treatment can reduce hypercalcemia and remove calcium deposits from the renal, cardiac, and gastric tissues. SEF treatment is useful in the regulation of disorders caused by an imbalance of serum electrolytes. This study experimentally demonstrates the favorable effects of SEF treatment on Vit D3-induced hypercalcemia. For small animals, the larger the body surface area per body weight becomes, the higher the therapeutic efficacy with SEF treatment.The purpose of this study was to elucidate the effects of static electric field (SEF) treatment on vitamin D3 (Vit D3)-induced hypercalcemia and renal calcification in mice. The mice were assigned to three groups: Vit D3-treated mice, mice treated with Vit D3 and SEF (Vit D3 + SEF), and untreated mice. After the administration of Vit D3, the Vit D3 + SEF-treated mice were exposed to SEF treatment by a high-voltage alternating current over five days. Serum biochemical examinations revealed that both the creatinine and blood urea nitrogen concentrations were significantly higher in the Vit D3-treated group. Significantly, decreased Cl concentrations, and increased Ca and inorganic phosphorus concentrations, were found in the Vit D3-treated group. In the Vit D3 + SEF-treated group, these parameters returned to the levels of the untreated group. In the Vit D3-treated group, histopathological examinations showed marked multifocal calcification in the lumens of the renal tubules and the renal parenchyma. The myocardium was replaced by abundant granular mineralization (calcification), with degeneration and necrosis of the calcified fibers. The stomach showed calcification of the cardiac mucosa. SEF treatment remarkably attenuated the Vit D3-induced hypervitaminotic injuries. In conclusion, this study provides important evidence that SEF treatment can reduce hypercalcemia and remove calcium deposits from the renal, cardiac, and gastric tissues. SEF treatment is useful in the regulation of disorders caused by an imbalance of serum electrolytes.
