BackgroundThe prevalence, disability rate and mortality rate of cerebral small vessel disease (CSVD) are relatively high among the elderly population, imposing a heavy burden on families and society. Among the various clinical manifestations of CSVD, cognitive impairment is the most common, and it is also the most closely related neuro-psychiatric syndrome to clinical practice in psychiatry. Previous studies on CSVD-related cognitive impairment (CSVD-CI) have mostly focused on the field of imaging, while studies on non-invasive electrophysiological and cerebral hemodynamic assessments are relatively scarce. ObjectiveTo analyze the characteristics of event-related potential (ERP) and functional near-infrared spectroscopy (fNIRS) in patients with CSVD-CI, and to explore their correlations with the severity of white matter lesions, in order to provide references for the objective assessment and early identification of CSVD-CI. MethodsA total of 40 patients with CSVD who met the diagnostic criteria of the Chinese Guideline for Diagnosis and Treatment of Cerebral Small Vessel Disease (2020) and had cognitive impairment, as well as were admitted to the Affiliated Hospital of North Sichuan Medical College from December 2024 to December 2025, were enrolled as the case group. Meanwhile, 40 healthy volunteers matched for gender, age and education level were recruited as the control group. Both groups underwent assessment using the Mini-Mental State Examination (MMSE), ERP-P300 detection, and fNIRS examination. The ERP-P300 indicators, functional connectivity strength of the whole brain and cognitive-related regions of interest (ROI) in fNIRS of the two groups were compared. The severity of the patients' white matter lesions was classified as follows: the Fazekas grade I group (mild white matter lesions) and the Fazekas grades II to III group (moderate to severe white matter lesions). Spearman correlation analysis was employed to investigate the correlation between the Fazekas grading of brain white matter lesions and the latency of ERP-P300, as well as the strength of functional connectivity measured by fNIRS. ResultsThe MMSE score of the CSVD-CI group was lower than that of the control group (Z=-6.250, P<0.01), and ERP-P300 lantency was significantly longer than that of the control group (t=12.291, P<0.01). The MMSE score of the sub-group with Fazekas grade I was higher than that of the sub-groups with grades II to III (Z=-2.420, P<0.05), and showed a shorter P300 latency than that of the sub-groups with grades II to III (Z=-4.210, P<0.01). All the differences were statistically significant. The resting-state whole-brain functional connectivity strength in the CSVD-CI group was lower than that in the control group, and the difference was statistically significant (t=10.243, P<0.05). Compared with the control group, the differences in the functional connectivity strength within the left premotor cortex (PMC), right PMC, left frontopolar cortex (FPC), right FPC, left dorsolateral prefrontal cortex (DLPFC), right DLPFC, left orbitofrontal cortex (OFC), and right OFC regions in the CSVD-CI group were all statistically significant (PFDR correction<0.01). The differences in the functional connectivity strength between multiple prefrontal-related brain regions between the CSVD-CI group and the control group were all statistically significant (PFDR correction<0.01). The severity of white matter lesions in CSVD-CI patients was positively correlated with the P300 latency (rs=0.891, P<0.05), and negatively correlated with the fNIRS functional connectivity strength (rs=-0.359, P<0.05). ConclusionPatients with CSVD-CI exhibit prolonged P300 latency, as well as decreased functional connectivity strength in multiple brain regions including the whole brain and the prefrontal lobe during the resting state. Moreover, these indicators are correlated with the severity of white matter lesions.

OBJECTIVE To provide references for medical institutions’ outpatient pharmacies to increase the scanning rate, scanning efficiency and scanning accuracy of drug traceability codes.METHODS A total of 4 157 unscanned traceability code records from the first two‑week period of June 2025 were selected from the outpatient pharmacy of our hospital. Pareto chart was adopted to analyze the reasons for unscanned codes, and the Objective-Rules-Training-Check-Culture (ORTCC) model was utilized to carry out fine management. The traceability code scanning rate, pharmacists’ work efficiency (number of prescriptions dispensed per pharmacist per hour, number of drug boxes dispensed per pharmacist per hour), patients’ medication-waiting time and dispensing errors were compared among four periods: before scanning implementation (June 2024), before management intervention (June 2025), the first phase after management (September 2025), and the second phase after management (December 2025), so as to evaluate the management effects.RESULTS The traceability code scanning rates in the first phase and second phase after management were remarkably higher than those before management ( P <0.05), and the scanning rate in the second phase after management was obviously higher than that in the first phase after management ( P <0.05). Compared with the period before scanning implementation, the number of prescriptions dispensed per pharmacist per hour, the number of drug boxes dispensed per pharmacist per hour, decreased significantly and patients’ medication-waiting time prolonged markedly before management ( P <0.05). In the second phase after management, both the number of prescriptions dispensed per pharmacist per hour and the number of drug boxes dispensed per pharmacist per hour increased significantly, and patients’ medication-waiting time shortened greatly in contrast with the status before management ( P <0.05). Besides, no statistically significant differences were found in the number of drug boxes dispensed per pharmacist per hour and patients’ medication-waiting time between the second phase after management and the period before scanning implementation ( P >0.05).After the implementation of traceability-code scanning management, dispensing errors presented a gradually declining trend in each stage.CONCLUSIONS The fine management system for outpatient drug traceability codes constructed based on Pareto chart and ORTCC model can improve the traceability code scanning rate and pharmacists’ work efficiency of outpatient pharmacies, and reduce drug dispensing errors.

Objective:To investigate the efficacy and safety of endovascular therapy (EVT) for early neurological deterioration (END) in patients with minor stroke due to acute anterior circulation large vessel occlusion.Methods:Consecutive patients with mild stroke due to acute anterior circulation large vessel occlusion admitted to Mianyang Central Hospital from October 2015 to October 2023 were included retrospectively. Minor stroke was defined as a baseline National Institutes of Health Stroke Scale (NIHSS) score <6. END was defined as an increase of ≥4 in NIHSS score compared to baseline within 12 hours of onset. According to whether EVT was performed or not, they were divided into EVT group and standard medical treatment (SMT) group. At 90 days after onset, the modified Rankin Scale was used to evaluate the outcome. 0-1 was defined as excellent outcome (primary outcome measure) and 0-2 was defined as good outcome (secondary outcome measure). The safety endpoints included symptomatic intracranial hemorrhage (sICH) within 72 hours after EVT and all-cause mortality within 90 days. Multivariate logistic regression analysis was used to determine the correlation between EVT and clinical outcome. Results:A total of 164 patients with minor stroke due to acute anterior circulation large vessel occlusion were included. Eighty-four patients (51.2%) developed END, of which 52 (61.9%) underwent EVT and 32 (38.1%) received SMT; 60 patients (71.4%) had excellent outcome, and 64 (76.2%) had good outcome. There was no significant difference in demographic and baseline clinical data between the EVT group and the SMT group. The excellent outcome rate of the EVT group at 90 days after onset showed a trend higher than that of SMT group (78.8% vs. 59.4%; χ2=3.680, P=0.055), but there was no significant difference in the good outcome rate and safety endpoints between the two groups. Multivariate logistic regression analysis showed that after adjusting for confounding factors, EVT was significantly and independently associated with excellent outcome at 90 days (odds ratio 4.955, 95% confidence interval 1.331-22.284; P=0.024). Conclusion:For patients with minor stroke due to anterior circulation large vessel occlusion who experience END, EVT may improve their functional outcome without increasing the risk of sICH and mortality.

Objective To investigate the impact of Qizhi Jiangtang Capsule (QZJT) on renal damage in diabetic nephropathy (DN) mice via NOD like receptors family pyrin domain containing 3/caspase-1/ Gasdermin D (NLRP3/caspase-1/GSDMD) signaling pathway. Methods Mice were randomly allocated into six experimental groups: a normal control group (NC), a diabetic nephropathy model group (DN), a low-dose QZJT treatment group (L-QZJT), a high-dose QZJT treatment group (H-QZJT), a positive control group administered Shenqi Jiangtang Granules (SQJT), and an ML385 group (treated with an inhibitor of nuclear factor erythroid 2-related factor 2, Nrf2). Upon successful model induction, therapeutic interventions were commenced. Renal function impairment in the mice was evaluated through quantification of fasting blood glucose (FBG), 24-hour urinary albumin (UAlb), serum creatinine (SCr), blood urea nitrogen (BUN), and the kidney-to-body mass ratio (K/B). Renal tissue pathology was evaluated using HE and PAS staining. Serum levels of inflammatory cytokines IL-1β and IL-18 were quantified by ELISA. Levels of podocyte markers and proteins involved in relevant pathways were assessed using Western blot analysis. Results Compared with the NC group, FBG, 24 h UAlb, SCr, and BUN were increased in the DN group, and the K/B mass ratio was also increased. In contrast, compared with the DN group, FBG, 24 h UAlb, SCr, and BUN in both the low-dose (L-QZJT) and high-dose Quanzhou Jintang (H-QZJT) groups were decreased, and the K/B mass ratio was decreased as well. The therapeutic efficacy of H-QZJT was comparable to that of Shenqi Jiangtang Granules. QZJT ameliorated renal histopathological injury in DN mouse, increased the protein levels of Nephrin (a podocyte marker), and decreased the protein levels of NLRP3, apoptosis-associated speck-like protein containing CARD (ASC), pro-caspase-1, and GSDMD-N. After ML385 treatment, renal cells exhibited swelling and morphological changes, the inflammatory infiltrate area was enlarged, the protein levels of NLRP3, ASC, pro-caspase-1, and GSDMD-N were up-regulated, and the levels of IL-1β and IL-18 were increased. Conclusion QZJT may inhibit podocyte pyroptosis by acting on the Nrf2 to regulate the NLRP3/caspase-1/GSDMD pathway, thus improving renal damage in DN mouse.

Stroke is a critical health issue in China, and carotid artery stenosis and plaque play key roles in its prevalence. Despite the acknowledged significance of this condition, detailed information regarding the prevalence of carotid artery stenosis and plaque across the Chinese population has been scarce. This study analyzed data from the China Stroke High-risk Population Screening and Intervention Program for 2020-2021, focusing on 194 878 Chinese adults aged 40 years and above. It assessed the prevalence of carotid artery stenosis and plaque and identified their associated risk factors. Results revealed a standardized prevalence of 0.40% for carotid artery stenosis and 36.27% for carotid plaque. Notably, the highest rates of stenosis were observed in north and south China at 0.61%, while southwestern China exhibited the highest plaque prevalence at 43.17%. Key risk factors included older age, male gender, hypertension, diabetes, stroke, smoking, and atrial fibrillation. This study highlights significant geographical and demographic disparities in the prevalence of these conditions, underlining the urgent need for targeted interventions and policy reforms. These measures are essential for reducing the incidence of stroke and improving patient outcomes, addressing this significant health challenge in China.

ObjectiveTo evaluate the effects of Tongnaoyin on the blood-brain barrier status and neurological impairment in acute ischemic stroke (AIS) patients with the syndrome of phlegm-stasis blocking collaterals by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). MethodsA total of 63 patients diagnosed with AIS in the Jiangsu Province Hospital of Chinese Medicine from October 2022 to December 2023 were enrolled in this study. According to random number table method,the patients were assigned into a control group (32 cases) and an observation group (31 cases). The control group received conventional Western medical treatment,and the observation group took 200 mL Tongnaoyin after meals,twice a day from day 2 of admission on the basis of the treatment in the control group. After 7 days of treatment,the patients were examined by DCE-MRI. The baseline data for two groups of patients before treatment were compared. The National Institute of Health Stroke Scale (NIHSS) score and modified Rankin Scale (mRS) score were recorded before treatment and after 90 days of treatment for both groups. The rKtrans,rKep,and rVe values were obtained from the region of interest (ROI) of the infarct zone/mirror area and compared between the two groups. ResultsThere was no significant difference in the NIHSS or mRS score between the two groups before treatment. After 90 days of treatment,the NIHSS and mRS scores declined in both groups,and the observation group had lower scores than the control group (P<0.05). After treatment,the rKtrans and rVe in the observation group were lower than those in the control group (P<0.01). ConclusionCompared with conventional Western medical treatment alone,conventional Western medical treatment combined with Tongnaoyin accelerates the repair of the blood-brain barrier in AIS patients,thereby ameliorating neurological impairment after AIS to improve the prognosis.
