OBJECTIVE To investigate the improvement effect and potential mechanism of Qingxue xiaozhi jiangtang formula on insulin resistance (IR) in type 2 diabetes mellitus (T2DM) rats. METHODS T2DM rat model was established by intraperitoneal injection of 30 mg/kg streptozotocin combined with high-fat and high-sugar diet. The rats were randomly divided into normal control group, model group, Qingxue xiaozhi jiangtang formula low-dose and high-dose groups (6.525, 13.05 g/kg, calculated by raw material) and metformin group (positive control, 0.18 g/kg), with 8 rats in each group. Administration groups were given relevant medicine intragastrically; normal control group and model group were given constant volume of normal saline intragastrically, once a day, for consecutive 6 weeks. Body mass and fasting blood glucose (FBG) were determined, and oral glucose tolerance test was conducted. Serum fasting insulin (FINS) level was measured to calculate the insulin resistance index (HOMA-IR) and insulin sensitivity index (ISI). Additionally, the level of serum lipids, liver function, oxidative stress indicators and inflammatory factors were assessed. The phosphorylation levels of kinase R-like endoplasmic reticulum kinase (PERK) and forkhead box O1 (FOXO1) protein in liver tissue of rats were determined. RESULTS Compared with model group, the body weight, ISI, the levels of high-density lipoprotein cholesterol and superoxide dismutase were increased significantly in Qingxue xiaozhi jiangtang formula high-dose group and metformin group (P<0.05); FBG, blood glucose level at 120 minutes of glucose loading, area under the curve of glucose, FINS, HOMA-IR, low-density lipoprotein cholesterol, total cholesterol, triglyceride, alanine transaminase, aspartate transaminase, alkaline phosphatase, malondialdehyde, interleukin-6, tumor necrosis factor-α, and C-reactive protein levels were significantly reduced (P< Δ0.05); the pathological damage of liver tissue had significantlyimproved, and the phosphorylation levels of PERK and FOXO1 proteins in liver tissue were significantly decreased (P<0.05). CONCLUSIONS Qingxue xiaozhi jiangtang formula can regulate glucose and lipid metabolism, inflammation factor and oxidative stress levels, and alleviate insulin resistance in T2DM rats. Its mechanism of action may be related to the inhibition of the PERK/FOXO1 signaling pathway.
2.Research advances in nonconvulsive status epilepticus
Journal of Apoplexy and Nervous Diseases 2025;42(8):711-717
Nonconvulsive status epilepticus (NCSE) is a state of persistent epileptic seizure characterized by disturbance of consciousness or major neurological deficits, without obvious limb convulsions. Due to a lack of obvious clinical manifestations and the potential risk of neurological damage, current research focuses on rapid identification, accurate classification, and optimization of treatment strategies. Since there is a lack of obvious motor symptoms in NCSE, it is difficult for clinicians to quickly identify the disease through traditional signs, which poses great challenges to diagnosis, and underdiagnosis may lead to delayed treatment and poor prognosis. This article systematically reviews the epidemiological characteristics, clinical manifestations, and key diagnostic points of NCSE and discusses existing treatment regimens and prognosis, in order to provide a reference for clinical practice.

ObjectiveTo prepare a rat model of heart failure after myocardial infarction by ligation of the anterior descending branch of the left coronary artery, and to observe the effect of Shenfu Yixin granules on the mitochondrial dynamics of rats with heart failure. MethodFifty SD male rats were randomly taken ten as the sham operation group and the rest as modeling group. The rat model of heart failure after myocardial infarction was prepared by ligation of anterior descending branch of left coronary artery. According to the left ventricular ejection fraction(LVEF) on the 28th day after operation, the model rats were randomly divided into the model group, Shenfu Yixin granule low-dose and high-dose groups(3.011, 15.055 g·kg-1) and sacubitril valsartan sodium group(20.83 mg·kg-1). Each administration group was gavaged daily with the corresponding dose of drug solution, while the sham operation group and model group were given the same amount of normal saline once a day for 28 days, with 6 rats in each group. Ultrasound was used to detect the cardiac function parameters, rat heart mass and body mass were weighed to calculate the cardiac mass index, enzyme linked immunosorbent assay(ELISA) was used to detect serum brain natriuretic peptide(BNP) and soluble growth stimulation expressed gene 2 protein(sST2) levels. Hematoxylin-eosin(HE) staining was used to observe the pathological morphology of the myocardium. Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) and Western blot were used to detect the mRNA and protein expression of mitochondrial fusion protein 1/2(Mfn1/2), optic atrophy protein 1(Opa1), dynamin-related protein 1(Drp1) and fission protein 1(Fis1). ResultCompared with the sham operation group, the mRNA and protein expression of LVEF, Mfn1, Mfn2, Opal in the model group decreased(P<0.05), while BNP, sST2, cardiac mass index, Drp1, Fis1 mRNA and protein levels increased(P<0.05). Compared with the model group, the expression of LVEF, Mfn1, Mfn2, Opal mRNA and protein increased in Shenfu Yixin granule high-dose and sacubitril valsartan sodium groups(P<0.05), while BNP, sST2, cardiac mass index, Drp1, Fis1 mRNA and protein levels decreased(P<0.05). Pathological observation showed that compared with the sham operation group, the model group had disordered arrangement of myocardial cells, inflammatory cell infiltration and myocardial fibrosis. Compared with the model group, the degree of inflammatory cell infiltration, myocardial or interstitial fibrosis was improved and alleviated in all administered groups. ConclusionShenfu Yixin granules can resist heart failure, reduce cardiac mass index, decrease BNP and sST2 contents, and improve cardiac function. Its mechanism may be related to the adjustment of mitochondrial dynamics.

ObjectiveTaking the oligosaccharides in Rehmanniae Radix(RR) as the research object, the content determination method based on high performance liquid chromatography-evaporative light scattering detection(HPLC-ELSD) and thin layer chromatography(TLC) identification method were established to explore the content and distribution of oligosaccharides in different RR herbs and decoction pieces. MethodA total of 10 batches of fresh and raw RR, 12 batches of RR decoction pieces and Rehmanniae Radix Praeparata(RRP) were collected. A TLC identification method for fructose, sucrose, manninotriose, raffinose and stachyose in RR was established by using silica gel G thin-layer plates with ethyl acetate-water-anhydrous formic acid-glacial acetic acid(12∶6∶5∶4) as the developing agent and 10% sulfuric acid-ethanol solution as chromogenic agent. A HPLC-ELSD was used to determine the contents of fructose, glucose, sucrose, melibiose, raffinose, manninotriose and stachyose in different RR herbs and decoction pieces. Then principal component analysis(PCA) and partial least squares-discriminant analysis(PLS-DA) were used to analyze the contents of 7 kinds of saccharides in RR herbs and decoction pieces, and the differential components were screened with the value of variable importance in the projection(VIP)>1. ResultThe results of TLC identification showed that fresh RR, raw RR and its decoction pieces showed spots of the same color on the corresponding positions with the control products of stachyose, raffinose and sucrose, while the TLC of RRP showed spots of the same color at corresponding positions to manninotriose and fructose controls. The results of methodological investigations of 7 analytes met the requirements of determination. Only glucose, sucrose, raffinose and stachyose were detected in 10 batches of fresh RR and 10 batches of raw RR herbs, the average contents of which were 0.84%, 4.62%, 2.42% and 57.90% in fresh samples, while those were 3.16%, 9.36%, 7.05% and 38.10% in raw samples, respectively. In 12 batches of RR decoction pieces, the contents of the above seven sugars(fructose, glucose, sucrose, melibiose, raffinose, manninotriose and stachyose) were 1.68%, 4.27%, 9.96%, 0.53%, 6.85%, 3.05% and 37.52%, respectively. In 12 batches of RRP, the contents of the above seven sugars were 10.62%, 11.01%, 1.25%, 3.35%, 1.12%, 28.16% and 6.39%, respectively. The results of multivariate statistical analysis showed that fresh RR, raw RR and RRP could be distinguished from each other by the contents of the 7 sugars, and the main differential components were stachyose, sucrose, raffinose and manninotriose. ConclusionIn terms of oligosaccharides, the contents and types of saccharides in different herbs and decoction pieces of RR are quite different, and the TLC identification method based on this can be used to distinguish raw RR from RRP, which can lay a foundation for improving the quality standard of RR and developing and applying oligosaccharides in different processed products of RR.

Objective To analysis the effectiveness and cost of Internet-based anticoagulation clinic versus traditional anticoagulation clinic treatment at Nanjing Drum Tower Hospital during the COVID-19 pandemic.Methods We reviewed and analyzed the clinical data of patients receiving anticoagulation management through Internet-based outpatient care and traditional outpatient care in Nanjing Drum Tower Hospital,from June 1,2020 to June 30,2021.Variability in time in therapeutic range(TTR)and international normalized ratio(INR)were calculated for enrolled patients.Patients meeting TTR≥60%and INR variability<0.65 were considered optimal anticoagulation quality.Cost-effectiveness analysis was conducted from the patients'perspective,with results expressed using the incremental cost-effectiveness ratio(ICER).Results In the"Internet-based anticoagulation outpatient care"and"traditional face-to-face anticoagulation outpatient care"groups,19 individuals(67.86%)and 67 individuals(76.14%)met the criteria for optimal anticoagulation quality,respectively.The mean TTR was(71.83±19.17)%in the Internet-based group and(71.74±23.41)%in the traditional face-to-face group,indicating similar levels of warfarin anticoagulation quality between the two groups.The ICER was calculated as 327.17 yuan,less than the per capita gross domestic product(GDP)of 2021.Conclusion During the COVID-19 pandemic,Nanjing Drum Tower Hospital's Internet-based anticoagulation outpatient care effectively complemented the government's epidemic control policies.It ensured equivalent anticoagulation outcomes and significantly reduced patients'financial burdens.This approach offers new insights and guidance for optimizing healthcare services in the post-pandemic era.
8.Interpretation of the International League Against Epilepsy/American Epilepsy Society joint report on revisiting the concept of drug-resistant epilepsy
Journal of Apoplexy and Nervous Diseases 2024;41(6):486-492
Despite the availability of novel anti-seizure medications(ASMs)in their third generation,one-third of the patients with epilepsy may progress to drug-resistant epilepsy(DRE).In 2010,the International League Against Epi-lepsy(ILAE)introduced the concept of DRE,which is still used today,and early diagnosis of DRE can facilitate timely preoperative evaluation for individuals with no response to ASMs,helping them to benefit from epilepsy surgery.Since the incidence rate of DRE remains high and there is a lack of update in related concepts,the ILAE/American Epilepsy Society(AES)Joint Translational Task Force discussed the heterogeneity,complexity,and dynamic changes of DRE manifesta-tions and mechanisms throughout the lifespan and across various species from the perspective of coordinating preclinical and clinical studies.The Joint Translational Task Force advocates the necessity of revisiting the current definition of DRE to enhance the clinical management of DRE,steer future research efforts towards DRE,and provide patients with more ef-fective and individualized treatment strategies,so as to reduce the incidence rate of DRE and improve the quality of life of patients.This article provides a concise overview and interpretation of the ILAE/AES report.

Purpose:
To understand the recurrence risk perception of stroke patients and develop a chain mediation model of recurrence risk perception and health behavior.
Methods:
A cross-sectional study and convenience sampling were used. Stroke survivors were recruited from the neurology departments of three tertiary hospitals. Their recurrence risk perception, behavioral decision-making, social support, self-efficacy, recurrence worry, and health behavior were measured by relevant tools. Data was analyzed through one-way analysis and regression analysis, and the AMOS 21.0 software was used to explore the mediating relationships between variables.
Results:
Of the 419 participants, 74.7% were aware of stroke recurrence risk. However, only 28.2% could accurately estimate their own recurrence risk. Recurrence risk perception was significantly correlated with behavioral decision-making, social support, self-efficacy, and health behavior (r = .19 ∼ .50, p < .05). Social support and recurrence risk perception could affect health behavior indirectly through self-efficacy, behavioral decision-making, and worry. Behavioral decision-making acted as a main mediator between recurrence risk perception and health behavior, while the path coefficient was .47 and .37, respectively. The chain mediation effect between recurrence risk perception and health behavior was established with a total effect value of .19 (p < .01).
Conclusion
Most stroke survivors could be aware of recurrence risk but failed to accurately estimate their individual risk. In the mediation model of recurrence risk perception and health behavior, social support seemed to be an important external factor, while self-efficacy, behavioral decision-making, and worry seemed to act as key internal factors.
