Clinical efficacy of Baijin pills in the treatment of generalized tonicclonic seizure epilepsy with cognitive impairment

BACKGROUND The generalized tonic-clonic seizure(GTCS)is the most usual variety of epileptic seizure.It is mainly characterized by strong body muscle rigidity,loss of consciousness,a disorder of plant neurofunction,and significant damage to cognitive function.The effect of antiepileptic drugs on cognition should also be considered.At present,there is no effective treatment for patients with epilepsy,but traditional Chinese medicine has shown a significant effect on chronic disease with fewer harmful side effects and should,therefore,be considered for the therapy means of epilepsy with cognitive dysfunction.AIM To investigate the clinical efficacy of Baijin pills for treating GTCS patients with cognitive impairment.METHODS This prospective study enrolled patients diagnosed with GTCS between January 2020 and December 2023 and separate them into two groups(experimental and control)using random number table method.The control group was treated with sodium valproate,and the experimental group was Baijin pills and sodium valproate for three months.The frequency and duration of each seizure,the Montreal Cognitive Assessment Scale(MoCA),and the Quality of Life Rating Scale(QOLIE-31)were recorded before and after treatment.RESULTS There were 85 patients included(42 in the control group and 43 in the experimental group).After treatment,the seizure frequency in the experimental group was significantly reduced(P<0.05),and seizure duration was shortened(P<0.01).The total MoCA score in the experimental group significantly increased compared to before treatment(P<0.01),and the sub-item scores,except naming and abstract generalization ability,significantly increased(P<0.05),whereas the total MoCA score in the control group significantly decreased after treatment(P<0.05).The QOLIE-31 score of the experimental group increased significantly after treatment compared to before treatment(P<0.01).CONCLUSION Baijin pills have a good clinical effect on epilepsy with cognitive dysfunction.

The potential role of Gegen Qinlian decoction in the treatment of coronavirus disease 2019 based on network pharmacology and validation of lipopolysaccharide-induced macrophages

Background:Coronavirus disease 2019(COVID-19)is caused by severe acute respiratory syndrome coronavirus 2,which has led to deaths and currently lacks an efficient treatment.Despite studies suggesting the potential of the Gegen Qinlian decoction(GQD)in preventing COVID-19,comprehensive analyses of its anti-COVID-19 potential are still lacking.Methods:GQD treatment was evaluated for its efficacy in ameliorating the early stage(24 hours)of lipopolysaccharide(LPS)-induced cytokine storm in vivo.Additionally,target genes of GQD were co-analyzed with COVID-19 signature genes to identify key ingredients and their pathways.Validation was also conducted using an LPS-induced macrophage model.Results:GQD treatment effectively ameliorated the early stage of LPS-induced cytokine storm in vivo.Key ingredients such as quercetin were found to be involved in multiple pathways,including inflammation,immunity,oxidative stress,cell proliferation,and apoptosis,through the AGE-RAGE signaling pathway and IL-17 signaling pathway.In the LPS-induced macrophage model,quercetin inhibited macrophage polarization(M1)and the secretion of inflammatory factors(IL-6,TNF-α,IL-17A).Conclusions:Our results indicate that GQD can be utilized in the treatment of cytokine storm induced by COVID-19 and has the potential to treat COVID-19 by suppressing the COVID-19 signature genes and macrophage polarization.

Value of Tongue Color Combined with Sublingual Microcirculation in Predicting the Severity of Mild to Moderate Acute Cerebral Infarction

Objective:To explore the value of tongue color combined with sublingual microcirculation in predicting the severity of mild to moderate acute cerebral infarction(ACI).Methods:From January to December 2022,90 patients with ACI were admitted to the Department of Neurology of Jiangsu Provincial Hospital of Integrated Traditional Chinese and Western Medicine.According to the NHISS score on the 5th day of admission,the patients were divided into mild group(35 cases)and moderate group(55 cases).The changes of tongue color and arterial lactate on the 5th day of admission were observed and monitored.Side-stream dark field imaging(SDF)was used to determine the total vascular density(TVD),perfused vascular density(PVD),perfused vascular ratio(PPV)and microvascular flow index(MFI).The multivariate logistic regression analysis was used to screen the risk factors for the severity of ACI,and the receiver operating characteristic curve(ROC)to evaluate their values in predicting ACI severity.Results:There was no significant difference in lactate between the two groups(P>0.05),and the frequency of red tongue in the mild group was higher,and the frequency of red tongue in the moderate group was significantly higher in the dark tongue group(P<0.05).The multivariate logistic regression analysis showed that PVD and PPV were independent risk factors for the severity of mild to moderate ACI(P<0.05).The ROC curve analysis showed that an area under the curve of 0.832 was achieved by the combination of PVD and PPV,which was larger than that of a single factor.Conclusion:Tongue color combined with sublingual microcirculation can be combined to predict the severity of mild to moderate ACI.

Retrospective study on Professor Zhongying Zhou's experience in Traditional Chinese Medicine treatment on diabetic nephropathy

OBJECTIVE:To study and analyze the etiology and pathogenesis,diagnosis and prescription for cases of diabetic nephropathy(DN) treated by Professor Zhongying Zhou(Prof.Zhou) with the help of dada mining technique,so as to inherit his clinical experience and academic thoughts.METHODS:After pretreatment of the medical record information,statistical software SPSS 13.0 was used to analyze and process the standardized data using the descriptive analysis,cluster analysis and association rules.RESULTS:Ninety-four entries derived from Traditional Chinese Medicine(TCM) four-diagnostic information were selected.Through data mining,the highest frequency was yellow-thin-greasy tongue coating,followed by dark tongue,and then by thready-slippery pulse.The main self-conscious symptoms were limb numbness,dry mouth,frequent micturition,etc.With respect to pathogenesis,the etiology related to kidney reached 73.46%.The frequency of pathological factors for deficiency,blood stasis,heat,dampness,phlegm and dryness were 137.65%,80.25%,78.40%,48.77%,21.60%,and 14.20% respectively.A total of 236 kinds of herbs were used 2913 person times,averaging 17.98 herbs per prescription.CONCLUSION:The pathological location of DN is in the kidney.The pathogenesis of the disease is deficiency in origin and excess in superficiality,the former of which include deficiency of the liver and kidney,and deficiency of both Qi and Yin.The main pathological factors are blood stasis,heat,dampness,phlegm,and dryness;and they act upon each other to form the complex pathogenesis in terms of blood stasis-heat,dampness-heat,phlegm-heat,and dryness-heat.All the above factors are always crucial in the aggravation of DN throughout the whole course of its pathological evolution.

Rat model of cholelithiasis with human gallstones implanted in cholestasis-induced virtual gallbladder

AIM:To facilitate translational research on cholelithiasis,we have developed a rat model of human gallstones by exploiting the unique biliopancreatic features of this species.METHODS:Under anesthesia,16 adult rats of equal genders underwent two times of abdominal surgery.First,their common bile duct(CBD)was ligated to cause cholestasis by total biliary obstruction(TBO).On day 0,1,3,7,14,21 and 28 after TBO,magnetic resonance imaging(MRI)was conducted to monitor the dilatation of the CBD,and blood was sampled to analyze total serum bilirubin(TSB).Secondly,on day 30,the abdomen was re-opened and gallstone(s)collected from human patients were implanted in the dilated CBD asa virtual gallbladder(VGB),which was closed by suture ligation.This rat cholelithiasis model was examined by MRI,clinical observation,microcholangiography and histology.RESULTS:All rats survived two laparotomies.After ligation,the CBD was dilated to a stable size of 4 to30 mm in diameter on day 21-28,which became a VGB.The rats initially showed signs of jaundice that diminished over time,which paralleled with the evolving TSB levels from 0.6±0.3 mg/d L before ligation,through a peak of 10.9±1.9 mg/dL on day 14,until a nearly normalized value after day 28.The dilated CBD with thickened wall allowed an incision for implantation of human gallstones of 1-10 mm in diameter.The rat cholelithiasis was proven by in vivo MRI and postmortem microcholangiography and histomorphology.CONCLUSION:A rat model cholelithiasis with human gallstones has been established,which proves feasible,safe,reliable,nontoxic and cost-effective.Given the gallstones of human origin,applications of this model may be of help in translational research such as optical detection and lysis of gallstones by systemic drug administration.

Objective:The objective of this study is to investigate the effect of mild moxibustion on quality of life of patients with type 2 diabetic peripheral neuropathy(DPN).Materials and Methods:Fifty‑five patients with type 2 DPN from October 2018 to July 2019 were recruited in the present study and randomly divided into two groups:27 cases in the control group and 28 cases in the intervention group.The control group received routine treatment of hypoglycemic,hypotensive,mecobalamin nutritional nerve,while the intervention group received mild moxibustion on the basis of the control group.The course of treatment for both groups was 10 weeks.The quality of life of the two groups was assessed using short form‑36 health survey and compared with t‑test at 0.05 significance level.Results:The total score of the short form‑36 in the intervention group was higher than the control group(P<0.05);the scores of bodily pain,physical functioning(PF),general health(GH),and mental health dimensions in the intervention group increased significantly compared with the control group(P<0.05);the scores of role physical,social functioning(SF),vitality,and role‑emotional(RE)dimensions showed no between‑group difference(P>0.05).Conclusion:Mild moxibustion can effectively improve the quality of life of patients with type 2 DPN,relieve patient pain symptoms,and improve PF and GH.

Shenning II Decoction Inhibits Epithelial-Mesenchymal Transition of Renal Tubular Epithelial Cells via Regulation of Wnt/<i>β</i>-Catenin Signaling

This study was conducted to investigate the effect of Shenning II decoction on renal function, renal pathology, epithelial-to-mesenchymal transition (EMT), and Wnt/beta-catenin signaling in unilateral ureteral obstruction (UUO) renal fibrosis. Sprague-Dawley rats were randomly divided into blank control, sham-operated, UUO model (untreated), and UUO with Shenning decoction treatment (high, medium, and low dose) groups. Renal function was evaluated based on blood urea nitrogen (BUN) and serum creatinine (Scr) levels. Histopathological analysis of rat kidney tubular tissue was carried out and E-cadherin, fibronectin, vimentin, Wnt4, glycogen synthase kinase (GSK)β, low-density lipoprotein receptor-related protein (LRP)5, LRP6, β-catenin, Snail, and fibroblast-specific protein (FSP)1 expression was evaluated by immunohistochemistry, western blotting, and real-time PCR. BUN and Scr were found to be increased in UUO when compared with the sham rats (P < 0.05), but this was reversed (albeit non-significantly) in rats treated with high and medium doses of Shenning II (P > 0.05). Shenning II decoction decreased histopathological scores relative to the UUO rats (P < 0.05). Protein expression of E-cadherin was increased, whereas that of vimentin, Wnt4, β-catenin, and fibronectin was decreased in Shenning I-treated rats, when compared with the untreated UUO rats, as determined by immunohistochemistry and western blotting (P < 0.05). Wnt4, β-catenin, GSK-3β, LRP5, LRP6, Snail, and FSP1 mRNA levels were also downregulated by Shenning II decoction treatment (P < 0.05). Shenning II decoction, therefore, protects against renal fibrosis by blocking renal tubular EMT via suppression of Wnt/beta-catenin signaling.

Alterations of Cerebral Functional Connectivity in Patients with Frontal Lobe Epilepsy:A Graph Theory Study

The aim of the present study is to investigate the brain functional network changes of patients with frontal lobe epilepsy(FLE)by resting-state functional magnetic resonance imaging(rsfMRI)and graph theoretical analysis.rsfMRI is performed in 46 adult patients with FLE and 46 age matched healthy controls(HCs).A functional network is built from these subjects,and the topological properties of such network are analyzed quantitatively using graph theoretical methods.According to the results,both FLE patients and HCs exhibit prominent small world features.Compared with HCs,FLE shows a decrease in local efficiency(Eloc),clustering coefficient,nodal efficiency as well as nodal degree.Furthermore,FLE(seven)has fewer hubs than HCs(ten).The functional abnormalities in the network organization suggest functional disturbances in patients with FLE.This study helps to gain new insights into the functional disorder in patients with FLE.The networks built here can also be a set of potential biomarkers for the diagnosis,monitoring and the treatment of FLE.

Differential diagnosis of gallstones by using hypericin as a fluorescent optical imaging agent

AIM: To explore the feasibility of using hypericin as an optical imaging probe with affinity for cholesterol for differential fluorescent detection of human gallstones.METHODS: Cholesterol, mixed and pigment stones from cholecystectomy patients were incubated with hypericin or solvent. After 72 h, the stones were analysed for fluorescence(365 nm) and treated with 2-propanol/dimethyl sulfoxide for high performance liquid chromatography(HPLC) analysis. Rats with virtual gallbladder containing human cholesterol, mixed or pigment gallstones(VGHG) received 5 mg/kg hypericin or solvent and VGHG rats with cholesterol stones were given different hypericin doses(5-15 mg/kg). Twelve hours later, the stones were analysed at 365 nm. Biliary excretion and metabolites of hypericin were assessed in common bile duct(CBD) cannulated rats for 9 h using fluorospectrometry, HPLC and matrixassisted laser desorption/ionization-time-of-flight mass spectrometry(MALDI-TOF MS).RESULTS: Homogeneous high fluorescence was seen on cholesterol stones either pre-incubated with hypericin or extracted from VGHG rats receiving hypericin. Mixed stones showed a dotted fluorescent pattern, whereas pigment and solvent-treated ones lacked fluorescence. HPLC showed 7.68, 6.65 and 0.08 × 10^(-3) M of cholesterol in extracts from cholesterol, mixed, and pigment gallstones, respectively. Hypericin accounted for 2.0, 0.5 and 0.2 × 10-6 M in that order. On cholesterol stones from VGHG rats receiving different hypericin doses, a positive correlation was observed between dose and fluorescence. In the bile from CBD-cannulated rats, fluorescence represented 20% of the injected dose with two peaks in 9 h. HPLC analysis revealed that hypericin conjugates reached 60% of the peak area. By MALDI-TOF MS, hypericinglucuronide was detected. CONCLUSION: This study proves the potential use of hypericin for differential fluorescent detection of human gallstones regarding their chemical composition.

Bifunctional staining for ex vivo determination of area at risk in rabbits with reperfused myocardial infarction

AIM: To develop a method for studying myocardial area at risk(AAR) in ischemic heart disease in correlation with cardiac magnetic resonance imaging(c MRI). METHODS: Nine rabbits were anesthetized, intubated and subjected to occlusion and reperfusion of the left circumflex coronary artery(LCx) to induce myocardial infarction(MI). ECG-triggered c MRI with delayed en-hancement was performed at 3.0 T. After euthanasia, the heart was excised with the LCx re-ligated. Bifunctional staining was performed by perfusing the aorta with a homemade red-iodized-oil(RIO) dye. The heart was then agar-embedded for ex vivo magnetic resonance imaging and sliced into 3 mm-sections. The AAR was defined by RIO-staining and digital radiography(DR). The perfusion density rate(PDR) was derived from DR for the AAR and normal myocardium. The MI was measured by in vivo delayed enhancement(i DE) and ex vivo delayed enhancement(e DE) c MRI. The AAR and MI were compared to validate the bifunctional straining for cardiac imaging research. Linear regression with Bland-Altman agreement, one way-ANOVA with Bonferroni's multiple comparison, and paired t tests were applied for statistics.RESULTS: All rabbits tolerated well the surgical procedure and subsequent c MRI sessions. The openchest occlusion and close-chest reperfusion of the LCx, double suture method and bifunctional staining were successfully applied in all animals. The percentage MI volumes globally(n = 6) and by slice(n = 25) were 36.59% ± 13.68% and 32.88% ± 12.38% on i DE, and 35.41% ± 12.25% and 32.40% ± 12.34% on e DE. There were no significant differences for MI determination with excellent linear regression correspondence(r global = 0.89; r slice = 0.9) between i DE and e DE. The percentage AAR volumes globally(n = 6) and by slice(n = 25) were 44.82% ± 15.18% and 40.04% ± 13.64% with RIO-staining, and 44.74% ± 15.98% and 40.48% ± 13.26% by DR showing high correlation in linear regression analysis(r global = 0.99; r slice = 1.0). The mean differences of the two AAR measurements on BlandAltman were almost zero, indicating RIO-staining and DR were essentially equivalent or inter-replaceable. The AAR was significantly larger than MI both globally and slice-by-slice(P < 0.01). After correction with the background and the blank heart without bifunctional staining(n = 3), the PDR for the AAR and normal myocardium was 32% ± 15% and 35.5% ± 35%, respectively,which is significantly different(P < 0.001), suggesting that blood perfusion to the AAR probably by collateral circulation was only less than 10% of that in the normal myocardium.CONCLUSION: The myocardial area at risk in ischemic heart disease could be accurately determined postmortem by this novel bifunctional staining, which may substantially contribute to translational cardiac imaging research.

Potential active compounds and mechanisms of Shen-Qi-Yi-Chang granule for the treatment of colorectal cancer:an analysis of network pharmacology and molecular docking

Background:In recent years,herbal formulations have assumed an influential part in preventing and treating tumors.Shenqi Yichang granules(SQYCG)have proven effective in the adjuvant treatment of colorectal cancer(CRC),but their mechanism has not been elucidated.This study aimed to explore the potential active compounds and mechanisms of SQYCG in the treatment of CRC using network pharmacology and molecular docking.Methods:The active compounds and targets of SQYCG and the CRC genes were found using the Traditional Chinese Medicine Systems Pharmacology,DrugBank,and DisGeNET databases.The intersected targets of disease genes and drug targets were depicted using a Venn diagram.The protein-protein interaction(PPI)network of these targets was obtained by String platform and visualized using Cytoscape.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis were carried using the DAVID database to obtain the core molecular mechanism of SQYCG in CRC treatment.Molecular docking techniques were used to validate the results.Results:A total of 63 compounds and 245 targets were obtained from the herbal prescription after the screening,of which 122 targets crossed with CRC genes.PPI showed that the core regulatory targets include MAPK1,TNF,TP53,JUN,RELA,MAPK14,and MAPK 8.The GO analysis indicated regulation of drug response,apoptotic process,response to hypoxia,angiogenesis,and response to lipopolysaccharide.KEGG pathway enrichment analysis mainly involves TNF,T cell receptor,Toll-like receptor,PI3K-Akt,and MAPK signal pathway.Conclusion:Through network pharmacology,we havedemonstrated that SQYCG has multiple targets,components,and pathways in treating CRC,with anti inflammation and inhibition of cell proliferation being critical components of its mechanism.

Puerarin alleviates sleep disorders in aged mice related to repairing intestinal mucosal barrier

More and more evidence suggests that puerarin,a potential remedy for gut inflammation,may have an ameliorative effect on sleep disturbances.However,the relationship between puerarin and sleep disruption has not been extensively researched.This study aims to explore the role and mechanisms of puerarin in improving sleep disorders.We established a light-induced sleep disorder model in mice and assessed the effects of puerarin on cognitive behavior using open field and water maze tests.Pathological detection demonstrated that sleep disturbances resulted in observable damage to the liver,lung,and kidney.Puerarin reversed multi-organ damage and inflammation.Further,puerarin activated paneth cells,resulting in increased lysozyme and TGF-βproduction,and stimulating intestinal stem cell proliferation.Puerarin also effectively inhibited the expression of F4/80,iNOS,TNF-α,and IL-1βin the small intestine,while it increased Chil3,CD206,and Arg-1 levels.Moreover,puerarin treatment significantly decreased P-P65,TLR4,Bcl-xl,and cleaved caspase-3 protein levels while increasing barrier protein levels,including ZO-1,Occludin,Claudin 1 and E-cadherin suggesting a reduction in inflammation and apoptosis in the gut.Overall,puerarin diminished systemic inflammation,particularly intestinal inflammation,and enhanced intestinal barrier integrity in mice with sleep disorders.Our findings suggest a potential new therapeutic pathway for sleep disorders.
