Altered synaptic currents,mitophagy,mitochondrial dynamics in Alzheimer's disease models and therapeutic potential of Dengzhan Shengmai capsules intervention

Emerging research suggests a potential association of progression of Alzheimer's disease(AD)with alterations in synaptic currents and mitochondrial dynamics.However,the specific associations between these pathological changes remain unclear.In this study,we utilized Aβ42-induced AD rats and primary neural cells as in vivo and in vitro models.The investigations included behavioural tests,brain magnetic resonance imaging(MRI),liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)analysis,Nissl staining,thioflavin-S staining,enzyme-linked immunosorbent assay,Golgi-Cox staining,transmission electron microscopy(TEM),immunofluorescence staining,proteomics,adenosine triphosphate(ATP)detection,mitochondrial membrane potential(MMP)and reactive oxygen species(ROS)assessment,mitochondrial morphology analysis,electrophysiological studies,Western blotting,and molecular docking.The results revealed changes in synaptic currents,mitophagy,and mitochondrial dynamics in the AD models.Remarkably,intervention with Dengzhan Shengmai(DZSM)capsules emerged as a pivotal element in this investigation.Aβ42-induced synaptic dysfunction was significantly mitigated by DZSM intervention,which notably amplified the frequency and amplitude of synaptic transmission.The cognitive impairment observed in AD rats was ameliorated and accompanied by robust protection against structural damage in key brain regions,including the hippocampal CA3,primary cingular cortex,prelimbic system,and dysgranular insular cortex.DZSM intervention led to increased IDE levels,augmented long-term potential(LTP)amplitude,and enhanced dendritic spine density and length.Moreover,DZSM intervention led to favourable changes in mitochondrial parameters,including ROS expression,MMP and ATP contents,and mitochondrial morphology.In conclusion,our findings delved into the realm of altered synaptic currents,mitophagy,and mitochondrial dynamics in AD,concurrently highlighting the therapeutic potential of DZSM intervention.

Capsule endoscopy and panendoscopy:A journey to the future of gastrointestinal endoscopy

In 2000,the small bowel capsule revolutionized the management of patients with small bowel disorders.Currently,the technological development achieved by the new models of double-headed endoscopic capsules,as miniaturized devices to evaluate the small bowel and colon[pan-intestinal capsule endoscopy(PCE)],makes this non-invasive procedure a disruptive concept for the management of patients with digestive disorders.This technology is expected to identify which patients will require conventional invasive endoscopic procedures(colonoscopy or balloon-assisted enteroscopy),based on the lesions detected by the capsule,i.e.,those with an indication for biopsies or endoscopic treatment.The use of PCE in patients with inflammatory bowel diseases,namely Crohn’s disease,as well as in patients with iron deficiency anaemia and/or overt gastrointestinal(GI)bleeding,after a non-diagnostic upper endoscopy(esophagogastroduodenoscopy),enables an effective,safe and comfortable way to identify patients with relevant lesions,who should undergo subsequent invasive endoscopic procedures.The recent development of magnetically controlled capsule endoscopy to evaluate the upper GI tract,is a further step towards the possibility of an entirely non-invasive assessment of all the segments of the digestive tract,from mouth-to-anus,meeting the expectations of the early developers of capsule endoscopy.

Integrated assessment of yield,nitrogen use efficiency and ecosystem economic benefits of use of controlled-release and common urea in ratoon rice production

Controlled-release urea(CRU)is commonly used to improve the crop yield and nitrogen use efficiency(NUE).However,few studies have investigated the effects of CRU in the ratoon rice system.Ratoon rice is the practice of obtaining a second harvest from tillers originating from the stubble of the previously harvested main crop.In this study,a 2-year field experiment using a randomized complete block design was conducted to determine the effects of CRU on the yield,NUE,and economic benefits of ratoon rice,including the main crop,to provide a theoretical basis for fertilization of ratoon rice.The experiment included four treatments:(i)no N fertilizer(CK);(ii)traditional practice with 5 applications of urea applied at different crop growth stages by surface broadcasting(FFP);(iii)one-time basal application of CRU(BF1);and(iv)one-time basal application of CRU combined with common urea(BF2).The BF1 and BF2 treatments significantly increased the main crop yield by 17.47 and 15.99%in 2019,and by 17.91 and 16.44%in 2020,respectively,compared with FFP treatment.The BF2 treatment achieved similar yield of the ratoon crop to the FFP treatment,whereas the BF1 treatment significantly increased the yield of the ratoon crop by 14.81%in 2019 and 12.21%in 2020 compared with the FFP treatment.The BF1 and BF2 treatments significantly improved the 2-year apparent N recovery efficiency,agronomic NUE,and partial factor productivity of applied N by 11.47-16.66,27.31-44.49,and 9.23-15.60%,respectively,compared with FFP treatment.The BF1 and BF2 treatments reduced the chalky rice rate and chalkiness of main and ratoon crops relative to the FFP treatment.Furthermore,emergy analysis showed that the production efficiency of the BF treatments was higher than that of the FFP treatment.The BF treatments reduced labor input due to reduced fertilization times and improved the economic benefits of ratoon rice.Compared with the FFP treatment,the BF1 and BF2 treatments increased the net income by 14.21-16.87 and 23.76-25.96%,respectively.Overall,the one-time blending use of CRU and common urea should be encouraged to achieve high yield,high nitrogen use efficiency,and good quality of ratoon rice,which has low labor input and low apparent N loss.

Effect of Polyvinyl Alcohol in Inner Aqueous Phase on Stability of Millimeter-scale Capsules

The millimeter-scale capsules with controllable morphology,ultra-low permeability and excellent mechanical stability were fabricated by millifluidics.Viscosity of inner phase was adjusted to control the morphology and properties of the capsules.In detail,as the concentration of polyvinyl alcohol(PVA)increased from 0 to 8% in the inner phase of the capsules,the diameter of capsules decreased from 3.33 ± 0.01mm to 2.97 ± 0.01 mm,the shell thickness of capsules decreased from 0.183 ± 0.004 mm to 0.155 ± 0.003 mm.While the capsules had round shape and high sphericity.Notably,the capsules with 2% PVA in the inner phase had remarkably decreased water permeability and good morphological stability.Specifically,the end-time of water losing of the capsules was up to 49 days,while the dehydrated capsules maintained spherical appearance,and crushing force of the capsules was up to 13.73 ± 0.79 N,which ensured stability during processing and transportation.This research provides a new strategy for stable encapsulation of small molecules.

Expression Recognition Method Based on Convolutional Neural Network and Capsule Neural Network

Convolutional neural networks struggle to accurately handle changes in angles and twists in the direction of images,which affects their ability to recognize patterns based on internal feature levels. In contrast, CapsNet overcomesthese limitations by vectorizing information through increased directionality and magnitude, ensuring that spatialinformation is not overlooked. Therefore, this study proposes a novel expression recognition technique calledCAPSULE-VGG, which combines the strengths of CapsNet and convolutional neural networks. By refining andintegrating features extracted by a convolutional neural network before introducing theminto CapsNet, ourmodelenhances facial recognition capabilities. Compared to traditional neural network models, our approach offersfaster training pace, improved convergence speed, and higher accuracy rates approaching stability. Experimentalresults demonstrate that our method achieves recognition rates of 74.14% for the FER2013 expression dataset and99.85% for the CK+ expression dataset. By contrasting these findings with those obtained using conventionalexpression recognition techniques and incorporating CapsNet’s advantages, we effectively address issues associatedwith convolutional neural networks while increasing expression identification accuracy.

Ischemic colitis induced by a platelet-raising capsule: A case report

BACKGROUND Ischemic colitis(IC)is also known as colon ischemia and is caused by colon vascular occlusion or nonocclusion,which results in a reduced blood supply to the colon and is not significant enough to maintain the metabolic function of cells,leading to intestinal wall ischemia.Its main symptoms include abdominal pain,diarrhea,and bloody stool.In severe cases,intestinal gangrene,peritonitis,intestinal stenosis and even intestinal obstruction may occur.IC induced by long-term use of certain special drugs is relatively rare in clinical practice.This article describes the clinical diagnosis and treatment of a typical case and provides a new treatment idea for the treatment of IC.CASE SUMMARY The patient was admitted to the hospital with"abdominal pain for half a month and bloody stool with mucous and pus for 3 d"and was diagnosed with"IC".Symptomatic and supportive treatment,such as antibiotics(levofloxacin),acid inhibition and stomach protection,fluid replenishment,and intravenous nutrition,was given.The patient's colonic ulcers were considered to be related to the oral administration of platelet(PLT)-raising capsules;the patient was asked to stop PLT-raising drugs for selective review via colonoscopy,and antibiotics and mesalazine enteric-coated tablets were stopped.Under the guidance of hematology consultation,60 mg of methylprednisolone was given in combination with PLT infusion to increase the PLT.After treatment,the patient's condition stabilized,the patient’s stool turned yellow,the patient’s symptoms improved,and the patient was allowed to leave the hospital.CONCLUSION PLT-raising capsules can lead to IC,so clinicians should have a full understanding of the application of these drugs in the treatment of various causes of thrombocyt-INTRODUCTION Ischemic colitis(IC)is also known as colon ischemia(CI)and is caused by colon vascular occlusion or nonocclusion,which results in a reduced blood supply to the colon;this process is not significant enough to maintain the metabolic function of cells,leading to intestinal wall ischemia[1].Its main symptoms include abdominal pain,diarrhea,and bloody stool.In severe cases,intestinal gangrene,peritonitis,intestinal stenosis and even intestinal obstruction may occur[2,3].The pathogenesis of this disease has not been extensively studied,but increased clotting ability has been recognized as an important factor in the pathogenesis of IC[4].People older than 60 years(especially women)who suffer from certain underlying diseases,such as cardiovascular and cerebrovascular diseases,diabetes,and shock,are the most prone to colon IC.The lesions can involve any segment of the colon,among which the left half of the colon,such as the sigmoid colon,descending colon and spleen region,is the most common site of lesions.This is because the region south of the sigmoid colon is the"watershed region"of the colonic blood supply,where vascular dysplasia may easily cause ischemia.In addition,the left half of the colon is supplied by the inferior mesenteric artery,which is at an acute angle to the abdominal aorta and affects blood perfusion.The rectum is supplied by both the inferior mesenteric artery and the rectal artery,and ischemia is rare.Therefore,the IC lesions were mainly in the left colon,and most of them were of the first pass type.The disease is relatively mild and can be cured after conservative medical treatment,so the prognosis is favorable[5-7].Once ischemia improves,the patient’s condition can recover in a relatively short time,and this condition can be distin-guished from other types of enteritis[5-7],such as infectious colitis,inflammatory bowel disease,pseudomembranous enteritis,diverticulitis,colon cancer,and acute mesenteric ischemia.Clinically,ischemic colitis can be divided into gangrene and nongrene.The latter can also be subdivided into transient and chronic types.Treatment for IC usually includes fasting,gastrointestinal decompression,intravenous nutritional support,improved circulation,fluid resuscitation,empirical use of antibiotics and other symptomatic supportive treatments,and attention should be given to the treatment of the primary disease.Most patients will experience improvements in clinical symp-toms within 1 to 2 d,and patients with complications may require surgery.However,IC induced by long-term use of certain special drugs is relatively rare in clinical practice.This article describes the clinical diagnosis and treatment of a typical case and provides a new treatment idea for the treatment of ischemic colitis.

[Objectives]To observe the clinical efficacy of Sanying capsule combined with Xiaoying Patch in treating thyroid nodule(TN).[Methods]Two groups were treated similarly,with 200 cases in the control group undergoing basic treatment for 12 weeks and 198 cases in the observation group receiving Sanying capsule combined with Xiaoying patches for the same duration.The clinical symptoms,number of nodules,diameter of the largest nodule,and maximum reduction of nodules were observed before and after treatment.A control analysis was performed,and the underlying mechanisms were explored.[Results]The primary symptoms of the observation group exhibited a more favorable improvement than those of the control group.Additionally,the number of nodules decreased,the diameter of the largest nodule decreased,and the maximum reduction of nodules decreased in both groups following treatment.However,the observation group demonstrated a more pronounced improvement than the control group(P<0.05).[Conclusions]The combination of Sanying capsule and Xiaoying patch has been demonstrated to be an effective treatment for TN,with a high degree of reliability in terms of safety.

Detachable string magnetically controlled capsule endoscopy for the noninvasive diagnosis of esophageal diseases:A prospective,blind clinical study

BACKGROUND Traditional esophagogastroduodenoscopy(EGD),an invasive examination method,can cause discomfort and pain in patients.In contrast,magnetically controlled capsule endoscopy(MCE),a noninvasive method,is being applied for the detection of stomach and small intestinal diseases,but its application in treating esophageal diseases is not widespread.AIM To evaluate the safety and efficacy of detachable string MCE(ds-MCE)for the diagnosis of esophageal diseases.METHODS Fifty patients who had been diagnosed with esophageal diseases were pros-pectively recruited for this clinical study and underwent ds-MCE and conven-tional EGD.The primary endpoints included the sensitivity,specificity,positive predictive value,negative predictive value,and diagnostic accuracy of ds-MCE for patients with esophageal diseases.The secondary endpoints consisted of visualizing the esophageal and dentate lines,as well as the subjects'tolerance of the procedure.RESULTS Using EGD as the gold standard,the sensitivity,specificity,positive predictive value,negative predictive value,and diagnostic accuracy of ds-MCE for esophageal disease detection were 85.71%,86.21%,81.82%,89.29%,and 86%,respectively.ds-MCE was more comfortable and convenient than EGD was,with 80%of patients feeling that ds-MCE examination was very comfortable or comfortable and 50%of patients believing that detachable string v examination was very convenient.CONCLUSION This study revealed that ds-MCE has the same diagnostic effects as traditional EGD for esophageal diseases and is more comfortable and convenient than EGD,providing a novel noninvasive method for treating esophageal diseases.

Shugan Jieyu capsule effects on peripheral blood micro-124, micro- 132, and brain-derived neurotrophic factor in patients with mild to moderate depression

BACKGROUND To assess the effectiveness of Shugan Jieyu capsules on peripheral blood miR-124,miR-132,and brain-derived neurotrophic factor(BDNF)levels in patients with mild to moderate depression following coronary artery intervention[percuta-neous coronary intervention(PCI)]for coronary heart disease.Patients with mild-to-moderate depression of the liver-qi stagnation type after PCI for coronary heart disease at the 305th Hospital of the People’s Liberation Army were enrolled from June 2022 to November 2023 and randomly assigned to two groups:Experimental(treated with Shugan Jieyu capsules)and control(tr-eated with escitalopram oxalate tablets).This study compared the antidepressant effects of these treatments using 17-item Hamilton Rating Scale for Depression(HAMD-17)scores,metabolic equivalents,low-density lipoprotein cholesterol,BDNF,high-sensitivity C-reactive protein levels,miR-124 and miR-132 levels,distribution of immune-related lymphocyte subsets,and traditional Chinese me-dicine syndrome scores before and after 6 weeks of treatment.RESULTS No significant difference was observed in any index between the two groups before treatment(P>0.05).After treatment,the total efficacy rates were 93.33%and 90.00%in the experimental and control groups,respectively.Experimental group had significantly lower scores for the main and secondary syndromes compared to the control group(P<0.05).No significant difference was observed in the metabolic equivalents between the two groups be-fore and after treatment(P>0.05).The levels of low-density lipoprotein cholesterol,high-sensitivity C-reactive pro-tein,and miR-132 were significantly lower,whereas those of miR-124,BDNF,CD3+T lymphocytes,CD3+CD4+T helper lymphocytes,and CD3+CD4+/CD3+CD8+cells were significantly higher in the experimental group com-pared to the control group(P<0.05).The incidence of adverse reactions during experimental group was signi-ficantly lower than that in control group(P<0.05).CONCLUSION Shugan Jieyu capsules have good efficacy in patients with mild-to-moderate depression after PCI,and its me-chanism may contribute to the regulation of miR-124,miR-132,BDNF levels,and lymphoid immune cells.

Yiqi Tongluo capsule has protective effects against non-alcoholic fatty liver disease via regulating PI3K/AKT signaling

Background:Oxidative stress is one of the key elements in the progression of non-alcoholic fatty liver disease(NAFLD),and Yiqi Tongluo capsule(YTC)have a variety of physiological activities which include antioxidant.The purpose of this investigation was to discover the potential mechanisms of YTC ameliorates NAFLD.Methods:In this investigation,a high-fat diet(HFD)was adopted to establish a NAFLD mouse model.Liver samples were stained for oil red O and hematoxylin and eosin staining.The levels of total cholesterol(TC),triglyceride(TG),malondialdehyde(MDA),and superoxide dismutase(SOD)in the tissues were also detected.Network pharmacology was analyzed to filter out the key ingredients and targets of effect of YTC for the therapy of NAFLD.Subsequently,free fatty acids(FFA)was applied to induce Aml12 cells for in vitro experiments,and the cell samples were stained with oil red O and assayed for TC,TG,MDA,and SOD contents.At last,the Western blot technique was used to illuminate the pathway by which YTC plays a protective role against NAFLD.Results:Histopathological results demonstrated that YTC ameliorated tissue damage in the HFD-induced mouse model.At the same time,it also reduced the contents of TC,TG,MDA and increased the expression of SOD in the liver tissue of NAFLD mouse model.All of these findings demonstrate that YTC can play a role in the treatment of NAFLD by ameliorating oxidative stress.Network analysis of YTC ameliorates NAFLD mainly by modulating the PI3K-Akt signaling pathway.Follow-up in vitro experiments revealed that FFA caused lipid accumulation in Aml12 cells,which was dramatically reduced by YTC.Meanwhile,YTC could remarkably reduce the FFA-induced elevation of TC,TG,and MDA contents,and reverse the FFA-induced reduction of SOD contents.Western blot was verified for the PI3K-Akt signaling pathway.It was found that FFA could remarkably decrease the expression of p-PI3K,p-Akt,and p-GSK-3βproteins,which could be significantly increased after YTC treatment.Conclusions:The combination of network analysis prediction and experimental verification was used to identify the therapeutic effect of YTC on NAFLD.The protective effect was achieved by YTC through upregulation of PI3K-Akt-GSK-3βpathway.

Clinical Effect of Yinhuang Qingfei Capsules in Treatment of Asymptomatic and Mild/Common Severe Acute Respiratory Syndrome Coronavirus 2 Infection:An Analysis of 242 Cases

[Objectives]To investigate the clinical effect of Yinhuang Qingfei capsules in the treatment of asymptomatic and mild/common severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection.[Methods]A total of 362 patients with SARS-CoV-2 infection were divided into the treatment group with 242 patients and control group with 120 patients according to their treatment regimen.The patients in the control group were given standard treatment regimen and those in the treatment group were given Yinhuang Qingfei capsules in addition to the treatment in the control group.The two groups were observed in terms of average length of hospital stay,mean time for nucleic acid clearance,TCM syndrome score,and progression to severe/critical illness,and clinical outcome was compared between the two groups.[Results]There was a significant difference in the overall response rate between the treatment group and the control group[97.52%(236/242)vs 95.00%(114/120),P<0.05].Compared with the control group,the treatment group had significantly shorter length of hospital stay and time for nucleic acid clearance(P<0.05).After 7 days of treatment,both groups had a significant change in TCM syndrome score,and there was a significant difference in TCM syndrome score between the two groups(P<0.05);after 15 days of treatment,both groups had a TCM syndrome score of 0.Progression to severe/critical illness was not observed in either group.[Conclusions]Compared with the standard treatment regimen alone,standard treatment regimen combined with Yinhuang Qingfei capsules can effectively shorten the length of hospital stay and time for nucleic acid clearance and improve TCM symptoms in patients with asymptomatic and mild/common SARS-CoV-2 infection.

Study on the Efficacy of Shugan Jieyu Capsules Combined with Trazodone in Patients with Post-Stroke Depression and Insomnia

Objective:To analyze the effectiveness of applying ShuGan JieYu Capsules(SGJYC)combined with trazodone in patients with post-stroke depression(PSD)with insomnia.Methods:60 cases of PSD with insomnia patients admitted to the hospital from May 2022 to May 2023 were selected and randomly divided into a reference group(trazodone)and a research group(SGJYC combined with trazodone)of 30 cases each.Statistics were analyzed using the Hamilton Depression Rating Scale(HAM-D),Pittsburgh Sleep Quality Index(PSQI),and Activities of Daily Living(ADL)scale before treatment and 4,8,and 12 weeks after treatment.Results:Before treatment,The results of HAM-D,PSQI,and ADL scale studies in the two groups before treatment were not statistically significant(P>0.05);4,8,and 12 weeks after treatment,the results of HAM-D and PSQI studies in the research group were lower than that of the reference group,and the results of ADL scale studies were higher than that of the reference group.There was a significant difference between the groups(P<0.05).The total adverse reaction rate of the research group was lower than that of the reference group,and there was a significant difference between the groups(P<0.05).Conclusion:The combination of SGJYC and trazodone reduced depression in post-stroke patients,corrected insomnia,improved sleep quality,was safe,and had a low rate of adverse reactions.

Effects of mixed fertilizers formed by the compounding of two targeted controlled-release nitrogen fertilizers on yield,nitrogen use efficiency,and ammonia volatilization in double-cropping rice

One-time application of mixed fertilizer formed by the compounding of two controlled-release nitrogen fertilizers(CRUs)with targeted N supply during the periods from transplantation(TS)to panicle initiation(PI)and from PI to heading(HS)is expected to synchronize the double-peak N demand of rice.However,its effects on the yield and N use efficiency(NUE)of labor-intensive double-cropping rice were unknown.Two targeted CRU(CRU_(A)and CRU_(B))were compounded in five ratios(CRU_(A):CRU_(B)=10:0,7:3,5:5,3:7,and 0:10)to form five mixed fertilizers(BBFs):BBF1-5.A field experiment was performed to investigate the characteristics of N supply in early and late seasons under different BBFs and their effects on N uptake,yield,and ammonia volatilization(AV)loss from paddy fields of double-cropping rice.Conventional high-yield fertilization(CK,three split applications of urea)and zero-N treatments were established as controls.The N supply dropped significantly with the increased compound ratio of CRU_(B)during the period from TS to PI,but increased during the period from PI to HS.With the exception of the period from TS to PI in the late rice season,the N uptake of early and late rice maintained close synchronicity with the N supply of BBFs during the double-peak periods.Excessive N supply(BBF1 and BBF2)in the late rice season during the period from TS to PI increased N loss by AV.The effect of BBF on grain yield increase varied widely between seasons,irrespective of year.Among the BBFs,the BBF2 treatment of early rice not only stabilized the spikelets per panicle but also ensured a high number of effective panicles by promoting N uptake during the period from TS to PI and a high grain-filling percentage by appropriately reducing the N supply at the later PI stage,resulting in the highest rice yield.While stabilizing the effective panicle number,the BBF4 treatment of late rice increased the number of spikelets per panicle by promoting N uptake during the period from PI to HS,resulting in the highest rice yield.The two-year average yield and apparent N recovery efficiency of the BBF2 treatment during the early rice season were 9.6 t ha 1 and 45.3%,while those of late rice in BBF4 were 9.6 t ha 1 and 43.0%,respectively.The yield and NUE indexes of BBF2 in early rice and BBF4 in late rice showed no significant difference from those of CK.The AVs of BBF2 during the early rice season and of BBF4 during the late rice season were 50.0%and 76.8%lower,respectively,than those of CK.BBF2 and BBF4 could effectively replace conventional urea split fertilization in early and late rice seasons,ensuring rice yield and NUE and reducing AV loss in paddy fields.

Effect of the capsule on deformation and densification behavior of nickel-based superalloy compact during hot isostatic pressing

The Shima yield criterion used in finite element analysis for nickel-based superalloy powder compact during hot isostatic pressing(HIP) was modified through uniaxial compression experiments. The influence of cylindrical capsule characteristics on FGH4096M superalloy powder compact deformation and densification behavior during HIP was investigated through simulations and experiments. Results revealed the simulation shrinkage prediction fitted well with the experimental shrinkage including a maximum shrinkage error of 1.5%. It was shown that the axial shrinkage was 1.7% higher than radial shrinkage for a cylindrical capsule with the size of ∮50 mm × 100 mm due to the force arm difference along the axial and radial direction of the capsule. The stress deviated from the isostatic state in the capsule led to the uneven shrinkage and non-uniform densification of the powder compact. The ratio of the maximum radial displacement to axial displacement increased from0.47 to 0.75 with the capsule thickness increasing from 2 to 4 mm. The pressure transmission is related to the capsule thickness, the capsule material performance, and physical parameters in the HIP process.
