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.

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.

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.

Efficacy and safety of Lianhuaqingwen capsules in high-risk common type COVID-19 pneumonia:A multicenter retrospective study

Objective:To evaluate the clinical safety and efficacy of Lianhuaqingwen(LHQW)capsules in patients with high-risk common type COVID-19 pneumonia.Methods:A retrospective multicenter study on 383 high-risk common type COVID-19 pneumonia cases was conducted.Patients were categorized as the standard treatment(SDT)group(n=168)and the LHQW+SDT group(n=215).The primary endpoint was the rate of symptom(fever,fatigue,coughing)recovery and the secondary endpoints included the time to symptom recovery,the proportion of patients with improvement in chest CT images,the proportion of patients with clinical cure,the timing and rate of negative conversion of SARS-CoV-2 RNA assay.Results:The recovery rate was significantly higher in the LHQW+SDT group as compared with the SDT group(89.7%vs.72.0%,P<0.01).The combined use of LHQW+SDT also showed shorter time for symptom recovery,as well as shorter time for individual symptom of fever,fatigue and coughing recovery than use of SDT alone.A higher proportion of patients in the LHQW+SDT group with improvements in chest CT images and clinical cure(77.7%vs.57.1%,P<0.01)but the proportion of patients deteriorating to severe cases(1%vs.25%,P<0.01)in this group was significant lower than those in the SDT group.No significant difference in negative conversion rate of viral assay results was observed(76.8%vs.75.0%,P>0.05).No serious adverse events were reported.Conclusions:LHQW capsules could be recommended to ameliorate clinical symptoms and reduce the rate of deteriorating to severe cases for high-risk common type COVID-19 pneumonia.

LipoCol Forte capsules reduce the risk of liver cancer:A propensity score-matched,nationwide,population-based cohort study

BACKGROUND Liver cancer is among the top five most common cancers globally. Lipid-lowering drugs such as statins can lower the risk of liver cancer, but may also cause liver damage. LipoCol Forte capsules(LFC), a red yeast rice product, have demonstrated significant antihypercholesterolemic effects and a good safety profile in clinical studies.AIM To evaluate whether LFC lowers the risk of liver cancer in adults in this propensity score-matched, nationwide, population-based cohort study.METHODS We used data from Taiwan’s National Health Insurance Research Database, which includes electronic medical records for up to 99.99% of Taiwan’s population. LFC users and LFC non-users were matched 1:1 by propensity scores between January 2010 and December 2017. All had followup data for at least 1 year. Statistical analyses compared demographic distributions including sex, age, comorbidities, and prescribed medications. Cox regression analyses estimated adjusted hazard ratios(aHRs) after adjusting for potential confounders.RESULTS We enrolled 33231 LFC users and 33231 non-LFC users(controls). No significant differences between the study cohorts were identified regarding comorbidities and medications [standardized mean difference(SMD) < 0.05]. At follow-up, the overall incidence of liver cancer was significantly lower in the LFC cohort compared with controls [aHR 0.91;95% confidence interval(CI): 0.86-0.95;P < 0.001]. The risk of liver cancer was significantly reduced in both females(aHR 0.87;95%CI: 0.8-0.94;P < 0.001) and males(aHR 0.93;95%CI: 0.87-0.98;P < 0.01) in the LFC cohort compared with their counterparts in the non-LFC cohort. The antitumor protective effects applied to patients with comorbidities(including hypertension, ischemic stroke, diabetes mellitus, hyperlipidemia, hepatitis B infection and hepatitis C infection). Those using LFC for more than 84 drug days had a 0.64-fold lower risk of liver cancer compared with controls(P < 0.001). Compared with controls, the risk of developing liver cancer in the LFC cohort progressively decreased over time;the lowest incidence of liver cancer occurred in LFC users followed-up for more than 6 years(27.44 vs 31.49 per 1,000 person-years;aHR 0.75;95%CI: 0.68-0.82;P < 0.001).CONCLUSION This retrospective cohort study indicates that LFC has a significantly protective effect on lowering the risk of liver cancer, in a dose-dependent and time-dependent manner.

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.

Automatic Extraction of Medical Latent Variables from ECG Signals Utilizing a Mutual Information-Based Technique and Capsular Neural Networks for Arrhythmia Detection

From a medical perspective,the 12 leads of the heart in an electrocardiogram(ECG)signal have functional dependencies with each other.Therefore,all these leads report different aspects of an arrhythmia.Their differences lie in the level of highlighting and displaying information about that arrhythmia.For example,although all leads show traces of atrial excitation,this function is more evident in lead II than in any other lead.In this article,a new model was proposed using ECG functional and structural dependencies between heart leads.In the prescreening stage,the ECG signals are segmented from the QRS point so that further analyzes can be performed on these segments in a more detailed manner.The mutual information indices were used to assess the relationship between leads.In order to calculate mutual information,the correlation between the 12 ECG leads has been calculated.The output of this step is a matrix containing all mutual information.Furthermore,to calculate the structural information of ECG signals,a capsule neural network was implemented to aid physicians in the automatic classification of cardiac arrhythmias.The architecture of this capsule neural network has been modified to perform the classification task.In the experimental results section,the proposed model was used to classify arrhythmias in ECG signals from the Chapman dataset.Numerical evaluations showed that this model has a precision of 97.02%,recall of 96.13%,F1-score of 96.57%and accuracy of 97.38%,indicating acceptable performance compared to other state-of-the-art methods.The proposed method shows an average accuracy of 2%superiority over similar works.

Treatment of 198 Cases of Thyroid Nodules with Sanying Capsule Combined with Xiaoying Patch

[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.

Helicobacter pylori infection may result in poor gastric cleanliness in magnetically controlled capsule gastroscopy examination: A singlecenter retrospective study

Objective:Magnetically controlled capsule gastroscopy(MCCG)is an effective method for screening gastric diseases;however,its performance may be affected by gastric cleanliness.We aimed to explore the correlation between Helicobacter pylori infection and the degree of gastric cleanliness in the MCCG.Methods:This retrospective study enrolled 297 participants from October 2020 to April 2024 at Sir Run Run Shaw Hospital,Zhejiang University School of Medicine.Participant characteristics,MCCG examination results,and(13)C-urea breath test(C13-UBT)results were collected.The gastric cleanliness in MCCG examinations was assessed using a gastric cleanliness score.Binary logistic regression was used to analyze the relationships among participant characteristics,H.pylori infection,and gastric cleanliness.Chi-square tests and Fisher's exact tests were used to analyze the relationships among gastric lesions,H.pylori infection,and gastric cleanliness.Results:Among the participants,24.2%had H.pylori infection,and 17.5%had poor gastric cleanliness.Hypertension(odds ratio[OR]:2.63;95%confidence interval[CI]:1.36e5.09;p?0.004)was associated with a greater likelihood of H.pylori infection.H.pylori infection(OR:3.76;95%CI:1.99e7.09;p<0.001)was an independent risk factor for poor gastric cleanliness in the MCCG.A significant disparity was noted in the prevalence of focal erosions(p<0.001),gastric ulcers(p?0.001),and positive gastric lesions(p?0.027)between the 2 groups with and without H.pylori infection.The proportion of positive gastric lesions was not significantly different between the good gastric cleanliness group and the poor gastric cleanliness group(25.7%vs.21.2%;p?0.490).Conclusion:The findings of this study revealed that H.pylori infection was associated with hypertension.H.pylori infection may lead to poor gastric cleanliness.Institutions are advised to perform C13-UBT before MCCG,and participants should be informed of the risk of poor gastric cleanliness if the results are positive.The decision to perform H.pylori eradication before MCCG should take into account patient willingness and the benefit-to-risk ratio.

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.
