Role of bisphosphonates in osteoporosis caused by adult growth hormone deficiency

In recent years,growth hormone and insulin-like growth factors have become key regulators of bone metabolism and remodeling,crucial for maintaining healthy bone mass throughout life.Studies have shown that adult growth hormone deficiency leads to alterations in bone remodeling,significantly affecting bone microarchitecture and increasing fracture risk.Although recombinant human growth hormone replacement therapy can mitigate these adverse effects,improving bone density,and reduce fracture risk,its effectiveness in treating osteoporosis,especially in adults with established growth hormone deficiency,seems limited.Bisphosphonates inhibit bone resorption by targeting farnesyl pyrophosphate synthase in osteoclasts,and clinical trials have confirmed their efficacy in improving osteoporosis.Therefore,for adult growth hormone deficiency patients with osteoporosis,the use of bisphosphonates alongside growth hormone replacement therapy is recommended.

TIPE2 is Essential for Apocynin-mediated Protection against Intestinal Ischemia/Reperfusion-induced Acute Lung Injury

Intestinal ischemia/reperfusion(II/R)is a severe clinical circumstance which is frequently apparent in situations including midgut volvulus,superior mesenteric vessels closure and hemorrhagic shock.II/R not only brings about severe intestinal local damage but also leads to remote organs injury including lung,liver etc[1].Lung injury is the most common and severe complications which manifested as pulmonary susceptibility,respiratory dysfunction,and even acute respiratory distress syndrome(ARDS)[2].

Refractory autoimmune hemolytic anemia in a patient with systemic lupus erythematosus and ulcerative colitis:A case report

BACKGROUND Ulcerative colitis(UC)and systemic lupus erythematosus(SLE)are both systemic immunoreactive diseases,and their pathogenesis depends on the interaction between genes and environmental factors.There are no reports of UC with SLE in China,but six cases of SLE with UC have been reported in China.The combination of these two diseases has distinct effects on the pathogenesis of both diseases.CASE SUMMARY A female patient(30 years old)came to our hospital due to dull umbilical pain,diarrhea and mucous bloody stool in August 2018 and was diagnosed with UC.The symptoms were relieved after oral administration of mesalazine(1 g po tid)or folic acid(5 mg po qd),and the patient were fed a control diet.On June 24,2019,the patient was admitted for treatment due to anemia and tinnitus.During hospitalization,the patient had repeated low-grade fever and a progressively decreased Hb level.Blood tests revealed positive antinuclear antibody test,positive anti-dsDNA antibody,0.24 g/L C3(0.9-1.8 g/L),0.04 g/L C4(0.1-0.4 g/L),32.37 g/L immunoglobulin(8-17 g/L),and 31568.1 mg/24 h total 24-h urine protein(0-150 mg/24 h).The patient was diagnosed with SLE involving the joints,kidneys and blood system.Previously reported cases of SLE were retrieved from PubMed to characterize clinicopathological features and identify prognostic factors for SLE.CONCLUSION The patient was discharged in remission after a series of treatments,such as intravenous methylprednisolone sodium succinate,intravenous human immunoglobulin,cyclophosphamide injection,and plasma exchange.After discharge,the patient took oral prednisone acetate tablets,cyclosporine capsules,hydroxychloroquine sulfate tablets and other treatments for symptoms and was followed up regularly for 1 month,after which the patient's condition continued to improve and stabilize.

Retrospective study of effect of whole-body vibration training on balance and walking function in stroke patients

BACKGROUND Dysfunction in stroke patients has been a problem that we committed to solve and explore.Physical therapy has some effect to regain strength,balance,and coordination.However,it is not a complete cure,so we are trying to find more effective treatments.AIM To observe the effect of whole-body vibration training(WVT)on the recovery of balance and walking function in stroke patients,which could provide us some useful evidence for planning rehabilitation.METHODS The clinical data of 130 stroke participants who underwent conventional rehabilitation treatment in our hospital from January 2019 to August 2020 were retrospectively analyzed.The participants were divided into whole-body vibration training(WVT)group and non-WVT(NWVT)group according to whether they were given WVT.In the WVT group,routine rehabilitation therapy was combined with WVT by the Galileo Med L Plus vibration trainer at a frequency of 20 Hz and a vibration amplitude of 0+ACY-plusmn+ADs-5.2 mm,and in the NWVT group,routine rehabilitation therapy only was provided.The treatment course of the two groups was 4 wk.Before and after treatment,the Berg balance scale(BBS),3 m timed up-and-go test(TUGT),the maximum walking speed test(MWS),and upper limb functional reaching(FR)test were performed.RESULTS After 4 wk training,in both groups,the BBS score and the FR distance respectively increased to a certain amount(WVT=46.08±3.41 vs NWVT=40.22±3.75;WVT=20.48±2.23 vs NWVT=16.60±2.82),with P<0.05.Furthermore,in the WVT group,both BBS score and FR distance(BBS:18.32±2.18;FR:10.00±0.92)increased more than that in the NWVT group(BBS:13.29±1.66;FR:6.16±0.95),with P<0.05.Meanwhile,in both groups,the TUGT and the MWS were improved after training(WVT=32.64±3.81 vs NWVT=39.56±3.68;WVT=12.73±2.26 vs NWVT=15.04±2.27,respectively),with P<0.05.The change in the WVT group(TUGT:17.49±1.88;MWS:6.79±0.81)was greater than that in the NWVT group(TUGT:10.76±1.42;MWS:4.84±0.58),with P<0.05.CONCLUSION The WVT could effectively improve the balance and walking function in stroke patients,which may be good for improving their quality of life.

Abnormal brain activity in adolescents with Internet addiction who attempt suicide: an assessment using functional magnetic resonance imaging

Internet addiction is associated with an increased risk of suicidal behavior and can lead to brain dysfunction among adolescents.However,whether brain dysfunction occurs in adolescents with Internet addiction who attempt suicide remains unknown.This observational cross-sectional study enrolled 41 young Internet addicts,aged from 15 to 20 years,from the Department of Psychiatry,the First Affiliated Hospital of Chongqing Medical University,China from January to May 2018.The participants included 21 individuals who attempted suicide and 20 individuals with Internet addiction without a suicidal attempt history.Brain images in the resting state were obtained by a 3.0 T magnetic resonance imaging scanner.The results showed that activity in the gyrus frontalis inferior of the right pars triangularis and the right pars opercularis was significantly increased in the suicidal attempt group compared with the non-suicidal attempt group.In the resting state,the prefrontal lobe of adolescents who had attempted suicide because of Internet addiction exhibited functional abnormalities,which may provide a new basis for studying suicide pathogenesis in Internet addicts.The study was authorized by the Ethics Committee of Chongqing Medical University,China(approval No.2017 Scientific Research Ethics(2017-157))on December 11,2017.

Pedicle Screw Fixation with Kyphoplasty Decreases the Fracture Risk of the Treated and Adjacent Non-treated Vertebral Bodies:a Finite Element Analysis

Adjacent vertebral fractures are common in patients with osteoporotic vertebral compression fractures（OVCFs） after kyphoplasty.This finite element study was to examine whether short segment pedicle screw fixation（PSF） with kyphoplasty may decrease the fracture risk of the treated and adjacent non-treated vertebrae after kyphoplasty for OVCFs.By simulating cement augmentation with or without short segment pedicle screw fixation（PSF）,two tridimensional,anatomically detailed finite element models of the T10–L2 functional spinal junction were developed.The insertion of pedicle screws into the intact vertebra apparently decreased the stress distribution of the treated vertebra in vertical compression and other load situations.The stress distribution in the bone structures of the intact vertebra adjacent to the intact-screwed vertebra was much less than that in the one adjacent to the treated vertebra.The insertion of pedicle screws into the intact vertebra greatly decreased the maximum displacement of the cortical bones and cancellous bones of the vertebrae.Our results indicated that short segment PSF with kyphoplasty may decrease the fracture risk of the treated and adjacent non-treated vertebrae in the management of OVCFs.

Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China

Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

Adipogenesis Inhibitory Activity of Hypersampsone P from Hypericum subsessile

Adamantane polycyclic polyprenylated acylphloroglucinols(PPAPs)with caged architecture,a special class of hybrid natural products,is specifically rich in the plant family Guttiferae,especially Hypericum or Garcinia genus.Hypersampsone P is one of Adamantane PPAPs compounds extracted from Hypericum subsessile.Here we have chosen,screened ten PPAPs and identified one of them showed an activity in inhibiting of adipocytes differentiation.Particularly,the compound,hypersamp-sone P,blunted the adipocyte differentiation dose-dependently.Moreover,hypersampsone P down-regulated the expressions of several key regulators for adipogenesis,including PPARγand FABP4.The treatment of cells at the early stage of adipo-genesis by hypersampsone P induced the greatest blunting of adipocyte differentiation and the effect might be involved in the LKB1-AMPK signaling pathway.

Eight hub genes as potential biomarkers for breast cancer diagnosis and prognosis:A TCGA-based study

BACKGROUND Breast cancer(BC)is the most common malignant tumor in women.AIM To investigate BC-associated hub genes to obtain a better understanding of BC tumorigenesis.METHODS In total,1203 BC samples were downloaded from The Cancer Genome Atlas database,which included 113 normal samples and 1090 tumor samples.The limma package of R software was used to analyze the differentially expressed genes(DEGs)in tumor tissues compared with normal tissues.The cluster Profiler package was used to perform Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis of upregulated and downregulated genes.Univariate Cox regression was conducted to explore the DEGs with statistical significance.Protein-protein interaction(PPI)network analysis was employed to investigate the hub genes using the CytoHubba plug-in of Cytoscape software.Survival analyses of the hub genes were carried out using the Kaplan-Meier method.The expression level of these hub genes was validated in the Gene Expression Profiling Interactive Analysis database and Human Protein Atlas database.RESULTS A total of 1317 DEGs(fold change>2;P<0.01)were confirmed through bioinformatics analysis,which included 744 upregulated and 573 downregulated genes in BC samples.KEGG enrichment analysis indicated that the upregulated genes were mainly enriched in the cytokine-cytokine receptor interaction,cell cycle,and the p53 signaling pathway(P<0.01);and the downregulated genes were mainly enriched in the cytokine-cytokine receptor interaction,peroxisome proliferator-activated receptor signaling pathway,and AMP-activated protein kinase signaling pathway(P<0.01).CONCLUSION In view of the results of PPI analysis,which were verified by survival and expression analyses,we conclude that MAD2L1,PLK1,SAA1,CCNB1,SHCBP1,KIF4A,ANLN,and ERCC6L may act as biomarkers for the diagnosis and prognosis in BC patients.

Discussion about the Treatment of Alzheimer's Disease with Yisui Fuyong Decoction Based on Synaptic Plasticity

For Alzheimer's disease(AD),the earliest symptom is memory loss,which runs throughout the disease.The mutual growth and decline of long-term potentiation(LTP)and long-term depression(LTD)in synaptic plasticity is the basic condition of learning and memory.In the early stage of AD,there is no significant change in synaptic plasticity,so the treatment should mainly focus on warming yang and replenishing qi.In the middle stage of AD,LTP is continuously damaged and reduced,and synaptic plasticity is destroyed,such as weakness of the spleen and stomach,causing stagnation of endogenous retention of phlegm in the brain,so the treatment should focus on enriching yin and tonifying yang,resolving phlegm to remove stagnation.In the late stage of AD,due to excessive deposition of amyloid and other metabolites,neurotoxins are produced and brain atrophy is aggravated,such as depression leading to stasis,phlegm and stasis binding together,long term of stasis turning to heat toxin,which invades the brain,excessive heat damages yin,then both yin and yang are damaged,finally,the brain collateral loses nutrition,so the treatment should focus on replenishing essence and reinforcing marrow,detoxifying and resolving stasis.Yisui Fuyong Decoction can replenish essence and reinforce marrow to nourish yin,warm yang and tonify qi to strengthen yang,combine phlegm resolving,stasis elimination and collateral vessels dredging,realizing the treatment effects in all three stages of synaptic plasticity.

Mitophagy and cGAS-STING crosstalk in neuroinflammation

Mitophagy,essential for mitochondrial health,selectively degrades damaged mitochondria.It is intricately linked to the cGAS-STING pathway,which is crucial for innate immunity.This pathway responds to mitochondrial DNA and is associated with cellular stress response.Our review explores the molecular details and regulatory mechanisms of mitophagy and the cGAS-STING pathway.We critically evaluate the literature demonstrating how dysfunctional mitophagy leads to neuroinflammatory conditions,primarily through the accumulation of damaged mitochondria,which activates the cGAS-STING pathway.This activation prompts the production of pro-inflammatory cytokines,exacerbating neuroinflammation.This review emphasizes the interaction between mitophagy and the cGAS-STING pathways.Effective mitophagy may suppress the cGAS-STING pathway,offering protection against neuroinflammation.Conversely,impaired mitophagy may activate the cGAS-STING pathway,leading to chronic neuroinflammation.Additionally,we explored how this interaction influences neurodegenerative disorders,suggesting a common mechanism underlying these diseases.In conclusion,there is a need for additional targeted research to unravel the complexities of mitophagy-cGAS-STING interactions and their role in neurodegeneration.This review highlights potential therapies targeting these pathways,potentially leading to new treatments for neuroinflammatory and neurodegenerative conditions.This synthesis enhances our understanding of the cellular and molecular foundations of neuroinflammation and opens new therapeutic avenues for neurodegenerative disease research.

The Therapeutic Effects of Baicalein on the Hepatopulmonary Syndrome in the Rat Model of Chronic Common Bile Duct Ligation

Background and Aims:Hepatopulmonary syndrome(HPS)is characterized by arterial oxygenation defects due to pulmonary vascular dilation in liver disease.To date,liver transplantation remains the only effective treatment for HPS.This study aimed to explore the preventative role of baicalein in HPS development.Methods:Sixty male rats were randomly assigned to three groups:sham,common bile duct ligation(CBDL),and baicalein,receiving intraperitoneal injections of baicalein(40 mg·kg1·d1,diluted in saline)for 21 days.Survival rate,liver and kidney function,and bile acid metabolism levels were evaluated.Liver and lung angiogenesis and hepatic glycogen staining were assessed,and the expression of relevant proteins was evaluated by immunohistochemistry.Results:Baicalein improved survival rates and hypoxemia in rats post-CBDL,reducing angiogenic protein levels and enhancing glucose homeostasis.Compared to the untreated group,baicalein suppressed the expression of vascular endothelial growth factor,placental growth factors,matrix metalloprotease 9 and C-X-C motif chemokine 2,and it increased the expression of glycemic regulatory proteins,including dipeptidyl peptidase-4,sirtuin 1,peroxisome proliferatoractivated receptor gamma co-activator 1,and 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3.Conclusion:Baicalein significantly improves hepatic function and hypoxia in HPS rats by attenuating pathological angiogenesis in the liver and lungs,showing promise as a treatment for HPS.
