Fecal microbiota transplantation:whole grain highland barley improves glucose metabolism by changing gut microbiota

Highland barley(HB)is a high-altitude cereal with rich nutritional components and potential health benefits.To clarify its hypoglycemic effect and mechanism,we investigated the effect of whole grain HB and fecal microbiota transplantation(FMT)on glucose metabolism and gut microbiota in high-fat diet and streptozotocin(HFD/STZ)-induced diabetic mice.The results showed that HB(40%)significantly decreased fasting blood glucose and the area under the glucose tolerance curve,significantly increased insulin secretion and improved insulin resistance in HFD/STZ-induced diabetic mice(P<0.05).Inflammatory factors and blood lipid indices were also significantly alleviated after 12 weeks of 40%HB intervention(P<0.05).Additionally,beneficial bacteria,such as Bifidobacterium and Akkermansia,were significantly enriched in the gut of diabetic mice after whole grain HB intervention.Meanwhile,the results of further FMT experiments verified that the fecal microbiota after the 40%HB intervention not only significantly increased the relative abundance of Bifidobacterium and Akkermansia but also effectively improved glucose metabolism and alleviated the inflammatory state in HFD/STZ-induced diabetic mice.Collectively,our study confirmed the bridge role of gut microbiota in improving glucose metabolism of whole grain HB,which could promote the development of precision nutrition.

Enhancing metformin-induced tumor metabolism destruction by glucose oxidase for triple-combination therapy

Despite decades of laboratory and clinical trials,breast cancer remains the main cause of cancer-related disease burden in women.Considering the metabolism destruction effect of metformin(Met)and cancer cell starvation induced by glucose oxidase(GOx),after their efficient delivery to tumor sites,GOx and Met may consume a large amount of glucose and produce sufficient hydrogen peroxide in situ.Herein,a pH-responsive epigallocatechin gallate(EGCG)-conjugated low-molecular-weight chitosan(LC-EGCG,LE)nanoparticle(Met–GOx/Fe@LE NPs)was constructed.The coordination between iron ions(Fe3+)and EGCG in this nanoplatform can enhance the efficacy of chemodynamic therapy via the Fenton reaction.Met–GOx/Fe@LE NPs allow GOx to retain its enzymatic activity while simultaneously improving its stability.Moreover,this pH-responsive nanoplatform presents controllable drug release behavior.An in vivo biodistribution study showed that the intracranial accumulation of GOx delivered by this nanoplatform was 3.6-fold higher than that of the free drug.The in vivo anticancer results indicated that this metabolism destruction/starvation/chemodynamic triple-combination therapy could induce increased apoptosis/death of tumor cells and reduce their proliferation.This triple-combination therapy approach is promising for efficient and targeted cancer treatment.

Improvement of glucose metabolism in middle-aged mice on a high-fat diet by whole-grain highland barley is related to low methionine levels

Methionine restriction(MR)is an effective dietary strategy to regulate energy metabolism and alleviate oxidative stress and inflammation in the body,especially in the middle-aged and elderly population.However,the high methionine content of meat products makes this dietary strategy impossible to combine with protein supplementation and MR.Highland barley(HB),a low-methionine cereal,not only provides the body with protein but also has improved glucose metabolism and antioxidant and anti-inflammatory properties.Therefore,this study evaluated the feasibility of HB as a source of methionine-restricted dietary protein and the potential mechanisms.Middle-aged C57BL/6J mice were fed a control diet(CON),a high-fat diet(HFD),a whole-grain HB high-fat diet(HBHF),or a HBHF+methionine diet(HBHFmet)for 25 weeks.The results showed that the HBHF could keep the body weight,fasting glucose,insulin,homeostasis model assessment of insulin resistance(HOMA-IR),blood lipids,inflammation,and oxidative stress of HFD mice at normal levels.Compared with the HFD groups,HBHF inhibited pancreatic cell apoptosis and improved insulin secretion while improving hepatic and skeletal muscle glucose metabolism.However,these efficacies were attenuated in HBHFmet group mice.These findings suggest that HBHF has an MR strategy.

Voluntary wheel running ameliorated the deleterious effects of high-fat diet on glucose metabolism,gut microbiota and microbial-associated metabolites

Exercise training is critical for the early prevention and treatment of obesity and diabetes mellitus.However,the mechanism with gut microbiota and fecal metabolites underlying the effects of voluntary wheel running on high-fat diet induced abnormal glucose metabolism has not been fully elaborated.C57BL/6 male mice were randomly assigned to 4 groups according to diets(fed with normal chow diet or high-fat diet)and running paradigm(housed in static cage or with voluntary running wheel).An integrative 16S rDNA sequencing and metabolites profiling was synchronously performed to characterize the effects of voluntary wheel running on gut microbiota and metabolites.It showed that voluntary wheel running prevented the detrimental effects of high-fat feeding on glucose metabolism 16S rDNA sequencing showed remarkable changes in Rikenella and Marvinbryantia genera.Metabolic profiling indicated multiple altered metabolites,which were enriched in secondary bile acid biosynthesis signaling.In conclusion,our study indicated that voluntary wheel running significantly improved glucose metabolism and counteracted the deleterious effects of high-fat feeding on body weight and glucose intolerance.We further found that voluntary wheel running could integratively program gut microbiota composition and fecal metabolites changes,and may regulate muricholic acid metabolism and secondary bile acid biosynthesis in high-fat fed mice.

Effects of exercise training on glucose metabolism indicators and inflammatory markers in obese children and adolescents:A metaanalysis

BACKGROUND Obesity in children and adolescents is a serious problem,and the efficacy of exercise therapy for these patients is controversial.AIM To assess the efficacy of exercise training on overweight and obese children based on glucose metabolism indicators and inflammatory markers.METHODS The PubMed,Web of Science,and Embase databases were searched for randomized controlled trials related to exercise training and obese children until October 2023.The meta-analysis was conducted using RevMan 5.3 software to evaluate the efficacy of exercise therapy on glucose metabolism indicators and inflammatory markers in obese children.RESULTS In total,1010 patients from 28 studies were included.Exercise therapy reduced the levels of fasting blood glucose(FBG)[standardized mean difference(SMD):-0.78;95%confidence interval(CI):-1.24 to-0.32,P=0.0008],fasting insulin(FINS)(SMD:-1.55;95%CI:-2.12 to-0.98,P<0.00001),homeostatic model assessment for insulin resistance(HOMA-IR)(SMD:-1.58;95%CI:-2.20 to-0.97,P<0.00001),interleukin-6(IL-6)(SMD:-1.31;95%CI:-2.07 to-0.55,P=0.0007),C-reactive protein(CRP)(SMD:-0.64;95%CI:-1.21 to-0.08,P=0.03),and leptin(SMD:-3.43;95%CI:-5.82 to-1.05,P=0.005)in overweight and obese children.Exercise training increased adiponectin levels(SMD:1.24;95%CI:0.30 to 2.18,P=0.01)but did not improve tumor necrosis factor-alpha(TNF-α)levels(SMD:-0.80;95%CI:-1.77 to 0.18,P=0.11).CONCLUSION In summary,exercise therapy improves glucose metabolism by reducing levels of FBG,FINS,HOMA-IR,as well as improves inflammatory status by reducing levels of IL-6,CRP,leptin,and increasing levels of adiponectin in overweight and obese children.There was no statistically significant effect between exercise training and levels of TNF-α.Additional long-term trials should be conducted to explore this therapeutic perspective and confirm these results.

Intermittent fasting boosts antitumor immunity by restricting CD11b^(+)Ly6C^(low)Ly6G^(low) cell viability through glucose metabolism in murine breast tumor model

Intermittent fasting can benefit breast cancer patients undergoing chemotherapy or immunotherapy.However,it is still uncertain how to select immunotherapy drugs to combine with intermittent fasting.Herein we observed that two cycles of fasting treatment significantly inhibited breast tumor growth and lung tissue metastasis,as well as prolonged overall survival in mice bearing 4T1 and 4T07 breast cancer.During this process,both the immunosuppressive monocytic-(M-)and granulocytic-(G-)myeloid-derived suppressor cell(MDSC)decreased,accompanied by an increase in interleukin(IL)7R^(+)and granzyme B^(+)T cells in the tumor microenvironment.Interestingly,we observed that Ly6G^(low)G-MDSC sharply decreased after fasting treatment,and the cell surface markers and protein mass spectrometry data showed potential therapeutic targets.Mechanistic investigation revealed that glucose metabolism restriction suppressed the splenic granulocytemonocyte progenitor and the generation of colony-stimulating factors and IL-6,which both contributed to the accumulation of G-MDSC.On the other hand,glucose metabolism restriction can directly induce the apoptosis of Ly6G^(low)G-MDSC,but not Ly6G^(high)subsets.In summary,these results suggest that glucose metabolism restriction induced by fasting treatment attenuates the immune-suppressive milieu and enhances the activation of CD3^(+)T cells,providing potential solutions for enhancing immune-based cancer interventions.

Glycolysis and glucose metabolism as a target for bioenergetic and neuronal protection in glaucoma

Vision is arguably our most valued sense,yet approximately 340 million people globally suffer blindness or moderate visual impairment,highlighting the need to further develop and advance treatments for ophthalmic diseases.Glaucoma refers to a group of ocular disorders united by a clinically characteristic optic neuropathy with associated retinal ganglion cell loss.

Glucose metabolism profile recorded by flash glucose monitoring system in patients with hypopituitarism during prednisone replacement

BACKGROUND Commonly used glucocorticoids replacement regimens in patients with hypopituitarism have difficulty mimicking physiological cortisol rhythms and are usually accompanied by risks of over-treatment,with adverse effects on glucose metabolism.Disorders associated with glucose metabolism are established risk factors of cardiovascular events,one of the life-threatening ramifications.AIM To investigate the glycometabolism profile in patients with hypopituitarism receiving prednisone(Pred)replacement,and to clarify the impacts of different Pred doses on glycometabolism and consequent adverse cardiovascular outcomes.METHODS Twenty patients with hypopituitarism receiving Pred replacement[patient group(PG)]and 20 normal controls(NCs)were recruited.A flash glucose monitoring system was used to record continuous glucose levels during the day,which provided information on glucose-target-rate,glucose variability(GV),period glucose level,and hypoglycemia occurrence at certain periods.Islet β-cell function was also assessed.Based on the administered Pred dose per day,the PG was then regrouped into Pred>5 mg/d and Pred≤5 mg/d subgroups.Comparative analysis was carried out between the PG and NCs.RESULTS Significantly altered glucose metabolism profiles were identified in the PG.This includes significant reductions in glucose-target-rate and nocturnal glucose level,along with elevations in GV,hypoglycemia occurrence and postprandial glucose level,when compared with those in NCs.Subgroup analysis indicated more significant glucose metabolism impairment in the Pred>5 mg/d group,including significantly decreased glucose-target-rate and nocturnal glucose level,along with increased GV,hypoglycemia occurrence,and postprandial glucose level.With regard to islet β-cell function,PG showed significant difference in homeostasis model assessment(HOMA)-β compared with that of NCs;a notable difference in HOMA-βwas identified in Pred>5 mg/d group when compared with those of NCs;as for Pred≤5 mg/d group,significant differences were found in HOMA-β,and fasting glucose/insulin ratio when compared with NCs.CONCLUSION Our results demonstrated that Pred replacement disrupted glycometabolic homeostasis in patients with hypopituitarism.A Pred dose of>5 mg/d seemed to cause more adverse effects on glycometabolism than a dose of≤5 mg/d.Comprehensive and accurate evaluation is necessary to consider a suitable Pred replacement regimen,wherein,flash glucose monitoring system is a kind of promising and reliable assessment device.The present data allows us to thoroughly examine our modern treatment standards,especially in difficult cases such as hormonal replacement mimicking delicate natural cycles,in conditions such as diabetes mellitus that are rapidly growing in worldwide prevalence.

Research progress on adaptive modifications of the gut microflora and regulation of host glucose and lipid metabolism by cold stimulation

The gut microflora is a combination of all microbes in intestine and their microenvironment,and its change can sensitively reflect the relevant response of the body to external environment and remarkably affect body's metabolism as well.Recent studies have found that cold exposure affects the body's gut microflora,which can lead to changes in the body's metabolism of glucose and lipid.This review summarizes recent research on the effects of cold exposure on gut microbes and metabolism of glucose and lipid,aiming to provide some new ideas on the approaches and measures for the prevention and treatment of diabetes and obesity.

Integration of root architecture,root nitrogen metabolism,and photosynthesis of‘Hanfu’apple trees under the cross-talk between glucose and IAA

Sugars and auxin have important effects on almost all phases of plant life cycle,which are so fundamental to plants and regulate similar processes.However,little is known about the effect of cross-talk between glucose and indole-3-acetic acid(IAA)on growth and development of apple trees.To examine the potential roles of glucose and IAA in root architecture,root nitrogen(N)metabolism and photosynthetic capacity in‘Hanfu’(Malus domestica),a total of five treatments was established:single application of glucose,IAA,and auxin polar transport inhibitor(2,3,5-triiodobenzoic acid,TIBA),combined application of glucose with TIBA and that of glucose with IAA.The combined application of glucose with IAA improved root topology system and endogenous IAA content by altering the mRNA levels of several genes involved in root growth,auxin transport and biosynthesis.Moreover,the increased N metabolism enzyme activities and levels of genes expression related to N in roots may suggest higher rates of transformation of nitrate(NO3--N)into amino acids application of glucose and IAA.Contrarily,single application of TIBA decreased the expression levels of auxin transport gene,hindered root growth and decreased endogenous IAA content.Glucose combined with TIBA application effectively attenuated TIBA-induced reductions in root topology structure,photosynthesis and N metabolism activity,and mRNA expression levels involved in auxin biosynthesis and transport.Taken together,glucose application probably changes the expression level of auxin synthesis and transport genes,and induce the allocation of endogenous IAA in root,and thus improves root architecture and N metabolism of root in soil with deficit carbon.

Characteristics of glucose and lipid metabolism and the interaction between gut microbiota and colonic mucosal immunity in pigs during cold exposure

Background Cold regions have long autumn and winter seasons and low ambient temperatures.When pigs are unable to adjust to the cold,oxidative damage and inflammation may develop.However,the differences between cold and non-cold adaptation regarding glucose and lipid metabolism,gut microbiota and colonic mucosal immunological features in pigs are unknown.This study revealed the glucose and lipid metabolic responses and the dual role of gut microbiota in pigs during cold and non-cold adaptation.Moreover,the regulatory effects of dietary glucose supplements on glucose and lipid metabolism and the colonic mucosal barrier were evaluated in cold-exposed pigs.Results Cold and non-cold-adapted models were established by Min and Yorkshire pigs.Our results exhibited that cold exposure induced glucose overconsumption in non-cold-adapted pig models(Yorkshire pigs),decreasing plasma glucose concentrations.In this case,cold exposure enhanced the ATGL and CPT-1αexpression to promote liver lipolysis and fatty acid oxidation.Meanwhile,the two probiotics(Collinsella and Bifidobacterium)depletion and the enrichment of two pathogens(Sutterella and Escherichia-Shigella)in colonic microbiota are not conducive to colonic mucosal immunity.However,glucagon-mediated hepatic glycogenolysis in cold-adapted pig models(Min pigs)maintained the stability of glucose homeostasis during cold exposure.It contributed to the gut microbiota(including the enrichment of the Rikenellaceae RC9 gut group,[Eubacterium]coprostanoligenes group and WCHB1-41)that favored cold-adapted metabolism.Conclusions The results of both models indicate that the gut microbiota during cold adaptation contributes to the protection of the colonic mucosa.During non-cold adaptation,cold-induced glucose overconsumption promotes thermogenesis through lipolysis,but interferes with the gut microbiome and colonic mucosal immunity.Furthermore,glucagon-mediated hepatic glycogenolysis contributes to glucose homeostasis during cold exposure.

Effects of vitamin D supplementation on glucose and lipid metabolism in patients with type 2 diabetes mellitus and risk factors for insulin resistance

BACKGROUND Type 2 diabetes mellitus(T2DM)is a chronic metabolic disease featured by insulin resistance(IR)and decreased insulin secretion.Currently,vitamin D deficiency is found in most patients with T2DM,but the relationship between vitamin D and IR in T2DM patients requires further investigation.AIM To explore the risk factors of IR and the effects of vitamin D supplementation on glucose and lipid metabolism in patients with T2DM.METHODS Clinical data of 162 T2DM patients treated in First Affiliated Hospital of Harbin Medical University between January 2019 and February 2022 were retrospectively analyzed.Based on the diagnostic criteria of IR,the patients were divided into a resistance group(n=100)and a non-resistance group(n=62).Subsequently,patients in the resistance group were subdivided to a conventional group(n=44)or a joint group(n=56)according to the treatment regimens.Logistic regression was carried out to analyze the risk factors of IR in T2DM patients.The changes in glucose and lipid metabolism indexes in T2DM patients with vitamin D deficiency were evaluated after the treatment.RESULTS Notable differences were observed in age and body mass index(BMI)between the resistance group and the non-resistance group(both P<0.05).The resistance group exhibited a lower 25-hydroxyvitamin D_(3)(25(OH)D_(3))level,as well as notably higher levels of 2-h postprandial blood glucose(2hPG),fasting blood glucose(FBG),and glycosylated hemoglobin(HbA1c)than the non-resistance group(all P<0.0001).Additionally,the resistance group demonstrated a higher triglyceride(TG)level but a lower high-density lipoprotein-cholesterol(HDL-C)level than the non-resistance group(all P<0.0001).The BMI,TG,HDL-C,25(OH)D_(3),2hPG,and HbA1c were found to be risk factors of IR.Moreover,the posttreatment changes in levels of 25(OH)D_(3),2hPG,FBG and HbA1c,as well as TG,total cholesterol,and HDL-C in the joint group were more significant than those in the conventional group(all P<0.05).CONCLUSION Patients with IR exhibit significant abnormalities in glucose and lipid metabolism parameters compared to the noninsulin resistant group.Logistic regression analysis revealed that 25(OH)D_(3)is an independent risk factor influencing IR.Supplementation of vitamin D has been shown to improve glucose and lipid metabolism in patients with IR and T2DM.

Short-term night lighting disrupts lipid and glucose metabolism in Zebra Finches:Implication for urban stopover birds

Night lighting has been shown to affect wild animals.To date,the effects of night lighting on the metabolic homeostasis of birds that spend short time in urban environments remain unclear.Using model bird species Zebra Finch(Taeniopygia guttata),we investigated the effects of short-term night lighting on liver transcriptome,blood glucose,triglyceride,and thyroxine(T4 and T3)levels in birds exposed to two different night lighting duration periods(three days and six days).After three days of night lighting exposure,the expression of genes involved in fat synthesis in the liver was upregulated while the expression of genes involved in fatty acid oxidation and triglyceride decomposition was downregulated.There was also a reduction in blood triglyceride,glucose,and T3 concentrations.However,after six days of night lighting,the expression of genes associated with fatty acid decomposition and hyperglycemia in the liver was upregulated,while the expression of genes involved in fat synthesis was downregulated.Simultaneously,blood glucose levels and T3 concentration increased.These findings indicate that short-term exposure to night lighting can disrupt the lipid and glucose metabolism of small passerine birds,and longer stopovers in urban area with intense night lighting may cause birds to consume more lipid energy.

Fibroblast growth factor 15,induced by elevated bile acids,mediates the improvement of hepatic glucose metabolism after sleeve gastrectomy

BACKGROUND Fibroblast growth factor(FGF)15/19,which is expressed in and secreted from the distal ileum,can regulate hepatic glucose metabolism in an endocrine manner.The levels of both bile acids(BAs)and FGF15/19 are elevated after bariatric surgery.However,it is unclear whether the increase in FGF15/19 is induced by BAs.Moreover,it remains to be understood whether FGF15/19 elevations contribute to improvements in hepatic glucose metabolism after bariatric surgery.AIM To investigate the mechanism of improvement of hepatic glucose metabolism by elevated BAs after sleeve gastrectomy(SG).METHODS By calculating and comparing the changes of body weight after SG with SHAM group,we examined the weight-loss effect of SG.The oral glucose tolerance test(OGTT)test and area under the curve of OGTT curves were used to assess the anti-diabetic effects of SG.By detecting the glycogen content,expression and activity of glycogen synthase as well as the glucose-6-phosphatase(G6Pase)and phosphoenolpyruvate carboxykinase(Pepck),we evaluated the hepatic glycogen content and gluconeogenesis activity.We examined the levels of total BA(TBA)together with the farnesoid X receptor(FXR)-agonistic BA subspecies in systemic serum and portal vein at week 12 post-surgery.Then the histological expression of ileal FXR and FGF15 and hepatic FGF receptor 4(FGFR4)with its corresponding signal pathways involved in glucose metabolism were detected.RESULTS After surgery,food intake and body weight gain of SG group was decreased compare with the SHAM group.The hepatic glycogen content and glycogen synthase activity was significantly stimulated after SG,while the expression of the key enzyme for hepatic gluconeogenesis:G6Pase and Pepck,were depressed.TBA levels in serum and portal vein were both elevated after SG,the FXR-agonistic BA subspecies:Chenodeoxycholic acid(CDCA),lithocholic acid(LCA)in serum and CDCA,DCA,LCA in portal vein were all higher in SG group than that in SHAM group.Consequently,the ileal expression of FXR and FGF15 were also advanced in SG group.Moreover,the hepatic expression of FGFR4 was stimulated in SG-operated rats.As a result,the activity of its corresponding pathway for glycogen synthesis:FGFR4-Ras-extracellular signal regulated kinase pathway was stimulated,while the corresponding pathway for hepatic gluconeogenesis:FGFR4-cAMP regulatory element-binding protein-peroxisome proliferator-activated receptorγcoactivator-1αpathway was suppressed.CONCLUSION Elevated BAs after SG induced FGF15 expression in distal ileum by activating their receptor FXR.Furthermore,the promoted FGF15 partly mediated the improving effects on hepatic glucose metabolism of SG.

NLRP3 Inflammasome in Relation to Glucose and Lipid Metabolism, and Insulin Resistance in Diabetes and Pre-Diabetes

Aims: To investigate the relationship among NLRP3 inflammasome, glucose and lipid metabolism, and insulin resistance (IR) in the serum of patients with diabetes and pre-diabetes. Methods: A total of 100 patients with abnormal blood glucose divided into the pre-diabetes mellitus (PDM) group (N = 46) and the type 2 diabetes mellitus (T2DM) group (N = 54). 20 normoglycemic subjects (NG, N = 20) were selected as a control group. The serum levels of glucose and lipid metabolism, IR, and the expression of NLRP3, ASC and Caspase-1 were measured. Besides, the correlations of NLRP3 inflammasome with glucose and lipid metabolism, and IR were analyzed. Results: Compared with the NG group, the levels of NLRP3, ASC, Caspase-1, FBG, HbA1C, TG, LDL-C, FINs, and HOMA-IR were higher (P β were lower (P P β were seen (P P β. Regression analysis further showed that blood glucose related indexes, FINs, and NLRP3 have made a decisive contribution to IR. Conclusions: Collectively, this evidence suggested that NLRP3 is closely related to glucose and lipid metabolism, and IR, and activated in PDM and T2DM.

Impact of inhaled and intranasal corticosteroids on glucose metabolism and diabetes mellitus:A mini review

Inhaled corticosteroids(ICS)and intranasal corticosteroids(INS)are the mainstays of treatment for chronic respiratory diseases like asthma,chronic obstructive pulmonary disease,and allergic rhinosinusitis.In addition,these localized forms of steroid therapy are generally considered to have fewer systemic side effects compared to long-term oral corticosteroids.However,concern and controversy remain over the impact of ICS and INS on the incidence and control of diabetes mellitus(DM).Given the widespread use of ICS and INS,even small individual effects on DM could lead to large consequences for the global population.Multiple large observational studies suggest that high dose ICS is associated with increased incident DM and worsened DM control,though the contribution of other risk factors is less certain.In addition,only two studies were done to investigate the association of INS and DM,with both studies demonstrating a short-term association of INS use with hyperglycemia.While more research evaluating the risk of ICS/INS for DM-related adverse events is needed,high doses of ICS/INS should be avoided when possible.The following strategies for ICS/INS dose minimization can be considered:Use of non-pharmacological measures(trigger avoidance,smoking cessation,vaccination to avoid infection),control of comorbid conditions,use of non-ICS-containing medications,intermittent rather than regular ICS dosing,and appropriate de-escalation of high ICS doses.

Glucose metabolism continuous deteriorating in male patients with human immunodeficiency virus accepted antiretroviral therapy for 156 weeks

BACKGROUND The dynamic characteristics of glucose metabolism and its risk factors in patients living with human immunodeficiency virus(PLWH)who accepted primary treatment with the efavirenz(EFV)plus lamivudine(3TC)plus tenofovir(TDF)(EFV+3TC+TDF)regimen are unclear and warrant investigation.AIM To study the long-term dynamic characteristics of glucose metabolism and its contributing factors in male PLWH who accepted primary treatment with the EFV+3TC+TDF regimen for 156 wk.METHODS This study was designed using a follow-up design.Sixty-one male treatmentnaive PLWH,including 50 cases with normal glucose tolerance and 11 cases with prediabetes,were treated with the EFV+3TC+TDF regimen for 156 wk.The glucose metabolism dynamic characteristics,the main risk factors and the differences among the three CD4+count groups were analyzed.RESULTS In treatment-naive male PLWH,regardless of whether glucose metabolism disorder was present at baseline,who accepted treatment with the EFV+3TC+TDF regimen for 156 wk,a continuous increase in the fasting plasma glucose(FPG)level,the rate of impaired fasting glucose(IFG)and the glycosylated hemoglobin(HbA1c)level were found.These changes were not due to insulin resistance but rather to significantly reduced isletβcell function,according to the homeostasis model assessment ofβcell function(HOMA-β).Moreover,the lower the baseline CD4+T-cell count was,the higher the FPG level and the lower the HOMA-βvalue.Furthermore,the main risk factors for the FPG levels were the CD3+CD8+cell count and viral load(VL),and the factors contributing to the HOMA-βvalues were the alanine aminotransferase level,VL and CD3+CD8+cell count.CONCLUSION These findings provide guidance to clinicians who are monitoring FPG levels closely and are concerned about IFG and decreased isletβcell function during antiretroviral therapy with the EFV+3TC+TDF regimen for long-term application.

Research progress on intervention of traditional Chinese medicine on myocardial glucose and lipid metabolism in heart failure

Disorder of energy metabolism is a major pathological change in the progression of heart failure.This process leads to insufficient myocardial energy and further aggravates cardiac dysfunction.Disorders of metabolic substrate utilization,mainly glucose and fatty acids,play an important role in this process.Research over the years has shown that some traditional Chinese medicines or compound prescriptions whose main role is to replenish qi and warm yang have good effects in regulating energy metabolism disorders.It has been found that some active ingredients in traditional Chinese medicine can regulate the uptake and utilization of myocardial cell metabolic substrate,so that the metabolism of myocardial cells can be adjusted in a direction that is beneficial to the body under hypoxic conditions,increasing the overall energy supply of the myocardium and improving heart function.This article reviewed the research of traditional Chinese medicine intervention on glucose and lipid metabolism of heart failure myocardial cells,and preliminarily summarizes the law and mechanism of traditional Chinese medicine intervention in heart failure myocardial glucose and fatty acid metabolism,hoping to provide clues for energy metabolism therapy research from the perspective of traditional Chinese medicine.

Global research trends and prospects of cellular metabolism in colorectal cancer

BACKGROUND An increasing number of studies have focused on the role of cellular metabolism in the development of colorectal cancer(CRC).However,no work is currently available to synthesize the field through bibliometrics.AIM To analyze the development in the field of“glucose metabolism”(GM),“amino acid metabolism”(AM),“lipid metabolism”(LM),and“nucleotide metabolism”(NM)in CRC by visualization.METHODS Articles within the abovementioned areas of GM,AM,LM and NM in CRC,which were published from January 1,1991,to December 31,2022,are retrieved from the Web of Science Core Collection and analyzed by CiteSpace 6.2.R4 and VOSviewer 1.6.19.RESULTS The field of LM in CRC presented the largest number of annual publications and the fastest increase in the last decade compared with the other three fields.Meanwhile,China and the United States were two of the most prominent contri-butors in these four areas.In addition,Gang Wang,Wei Jia,Maria Notar-nicola,and Cornelia Ulrich ranked first in publication numbers,while Jing-Yuan Fang,Senji Hirasawa,Wei Jia,and Charles Fuchs were the most cited authors on average in these four fields,respectively.“Gut microbiota”and“epithelial-mesenchymal transition”emerged as the newest burst words in GM,“gut microbiota”was the latest outburst word in AM,“metastasis”,“tumor microenvironment”,“fatty acid metabolism”,and“metabolic reprogramming”were the up-to-date outbreaking words in LM,while“epithelial-mesenchymal transition”and“apoptosis”were the most recently occurring words in NM.CONCLUSION Research in“cellular metabolism in CRC”is all the rage at the moment,and researchers are particularly interested in exploring the mechanism to explain the metabolic alterations in CRC.Targeting metabolic vulnerability appears to be a promising direction in CRC therapy.

Progress of Alzheimer＇s disease related glucose metabolism regulating hormones and a research perspective in nootropics of herbal medicine

Alzheimer’s disease as one of the neurodegenerative diseases, its pathological mechanisms still remains unclear. There’s evidence that diabetes is associated with Alzheimer’s disease. However, the fundamental cause of diabetes is abnormal glucose metabolism. There may be an inseparable relationship between glucose metabolism regulating hormones and Alzheimer’s disease. Here, we review the studies that connect the glucose metabolism regulating hormones to Alzheimer’s disease, and that suggest the quality of Alzheimer’s patients is improved by regulating glucose metabolism.
