ObjectivePolygoni Multiflori Radix is a commonly used tonic traditional Chinese medicine (TCM) in clinical practice, but liver injury has often been reported in recent years. Some related preparations containing Polygoni Multiflori Radix have been reported by the National Medical Products Administration many times for the risk of liver injury. This has caused extensive discussion on the potential toxicity of TCM in China and abroad, which has limited the clinical use of Polygoni Multiflori Radix to some extent. To understand the adverse reactions of Polygoni Multiflori Radix, the safe and rational use of Polygoni Multiflori Radix in clinical practice was discussed. MethodsThe pharmacovigilance thought of modern Chinese medicine and the TCM pharmacovigilance system framework of ''identification of poison, use of poison, anti-poison, and detoxification'' were employed to mine the relevant toxicity records, usage and dosage, processing compatibility, and contraindication of taking Polygoni Multiflori Radix in ancient books. The drug safety information of Polygoni Multiflori Radix was summarized by comparing with modern reports. ResultsA total of 74 ancient books related to Polygoni Multiflori Radix were included, suggesting that the toxicity of Polygoni Multiflori Radix was recognized in ancient times. The main chemical components of Polygoni Multiflori Radix had both efficacy and toxicity, and the adverse reactions may be related to long-term use, excessive use, and individual differences. The results showed that the toxic components of Polygoni Multiflori Radix could be reduced by peeling, steaming with black beans, and processing without iron tools. The toxic effects of Polygoni Multiflori Radix could be reduced by the compatibility of Polygoni Multiflori Radix with Poria, Psoraleae Fructus, and Cistanches Herba. ConclusionReasonable dosage, standard processing, correct compatibility, and syndrome differentiation are the key points to standardize the use of Polygoni Multiflori Radix and reduce the incidence of adverse reactions. Clinically, the toxicity classification of TCM should be strengthened, and the susceptible population should be prioritized. The detection indicators and early warning mechanisms should be improved, and precise drug dosage and course of treatment should be guaranteed. These measures can ensure the safe use of Polygoni Multiflori Radix.

BackgroundPatients with chronic schizophrenia often suffer from cognitive impairment. Traditional cognitive rehabilitation training has problems such as a single form and poor compliance, making it urgent to develop new cognitive intervention methods. ObjectiveTo explore the intervention effect of smartphone games on the cognitive function of patients with chronic schizophrenia, and to analyze the differences in cognitive function improvement between patients of different genders, in order to provide references for the cognitive function intervention of these patients. MethodsThis study was a prospective cohort study. A total of 30 patients who were hospitalized in the Psychiatry Department of Chaohu Hospital Affiliated to Anhui Medical University from March to October 2021, met the diagnostic criteria for schizophrenia as defined in the International Classification of Diseases, tenth edition (ICD-10), and had a disease duration of above 5 years, were selected as the research subjects. All patients received smartphone game intervention for 12 weeks, 5 times a week, each session lasting 1 hour, in addition to conventional antipsychotic drug treatment. At the baseline and at 3, 6, 9, and 12 weeks of the intervention, the cognitive function was evaluated using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), the Positive and Negative Syndrome Scale (PANSS) was used to assess mental symptoms, and the Problematic Mobile Gaming Questionnaire (PMGQ) was used to assess addiction symptoms. ResultsA total of 26 patients (86.67%) completed the study, including 13 females and 13 males. The time effects, group effects, and interaction effect between time and group for the immediate memory factor score of RBANS in the female group and the male group were all statistically significant (F=36.682, 5.712, 3.090, P<0.05 or 0.01), and the time effects and group effects for the verbal and delayed memory factors as well as the total score in both groups were also statistically significant (F=3.841, 6.149, 15.372, P<0.05 or 0.01). The time effects and group effects of the total score of PANSS in both groups had no statistical significance (F=2.041, 0.623, P>0.05 for both), and the interaction effect between time and group was statistically significant (F=5.728, P<0.01). The time effects, group effects, and interaction effect of the total score of PMGQ in both groups were all without statistical significance (F=2.672, 0.166, 0.642, P>0.05 for both). ConclusionSmartphone game intervention may help improve the cognitive function of patients with chronic schizophrenia (especially immediate memory, verbal function, and delayed memory), and the benefits are greater for female patients. The smartphone game intervention did not induce game addiction, but no significant improvement in psychotic symptoms was observed.

Objective To investigate the incidence and epidemiological characteristics of herpes zoster in Jinshan District, Shanghai, in 2024, and to provide a scientific basis for the development of prevention and control measures. Methods The visit information of herpes zoster cases in 2024 was collected through the outpatient diagnosis and treatment system of medical institutions in Jinshan District. Descriptive epidemiological methods were used for statistical analysis. Results In 2024, there were a total of 7 270 cases of herpes zoster in Jinshan District, including 3 398 male cases and 3 872 female cases. The incidence rate among females was higher than that among males (χ2 =125.25, P< 0.001). Cases occurred in all age groups, with an average age of 59.58 ± 15.28 years. The highest proportion of cases was in the 50-year-old group (21.99%) and the 60-year-old group (25.45%). The incidence rate increased with age (χ2 = 4 505.99, P< 0.001). The main departments for consultation were dermatology, pain clinics, and neurology. The main clinical diagnoses were herpes zoster without complications, postherpetic neuralgia, and incomplete herpes zoster. Among the cases, 3,102 patients had follow-up visits, and the number of follow-up visits increased with age. From 2020 to 2024, a total of 2,032 doses of herpes zoster vaccine were administered in the district, with the highest vaccination rate in the 50-year-old group (54.48%). Conclusion The majority of herpes zoster cases in Jinshan District are concentrated in the 50- and 60-year-old groups. The main complication is postherpetic neuralgia. The incidence rate and number of follow-up visits increase with age. The vaccination rate of herpes zoster vaccine in the entire district is relatively low. It is recommended to enhance monitoring and analysis, carry out health education for key populations (aged 50 years old and above), and promote vaccination and other preventive and control measures.

OBJECTIVE:
To observe the effect of electroacupuncture at "Sishencong" (EX-HN1) and "Fengchi" (GB20) on hippocampal neuronal ferritinophagy mediated by the nuclear receptor coactivator 4 (NCOA4)/ferritin heavy chain 1 (FTH1) signaling pathway in vascular dementia (VD) rats, and to explore the potential mechanisms of electroacupuncture for VD.
METHODS:
A total of 60 male rats of SPF grade were randomly divided into a blank group (12 rats), a sham surgery group (12 rats) and a modeling group (36 rats). In the modeling group, the modified 4-vessel occlusion method was used to establish the VD model. The 24 successfully modeled rats were randomly divided into a model group and an electroacupuncture group, with 12 rats in each group. In the electroacupuncture group, electroacupuncture was applied at left and right "Sishencong" (EX-HN1), and bilateral "Fengchi" (GB20), with continuous wave, in frequency of 2 Hz and current intensity of 1 mA, 30 min a time, once daily for 21 consecutive days. The learning and memory abilities were assessed using the Morris water maze test before modeling, after modeling and after intervention, as well as the novel object recognition test after intervention. After intervention, the neuronal morphology in the hippocampus was observed by Nissl staining; the iron deposition was observed by Prussian blue staining; the reactive oxygen species (ROS) level was detected by dihydroethidium (DHE) fluorescence staining; the levels of iron, malondialdehyde (MDA) and superoxide dismutase (SOD) in the hippocampal tissue were measured by the colorimetric assay, TBA method, and WST-1 method, respectively; the positive expression of NCOA4, FTH1 and glutathione peroxidase 4 (GPX4) was detected by immunohistochemistry; the protein expression of NCOA4, FTH1, GPX4, and the ratio of microtubule-associated protein 1 light chain 3B (LC3B) Ⅱ/Ⅰ in the hippocampus were detected by Western blot.
RESULTS:
Compared with the sham surgery group, in the model group, the escape latency was prolonged, and the number of platform crossings reduced (P<0.01), the recognition index (RI) was decreased (P<0.01); the hippocampal neurons displayed a blurred laminar structure, disorganized cellular arrangement, and the number of Nissl bodies was decreased (P<0.01); the percentage of iron deposition area in the hippocampus was increased (P<0.01); in the hippocampus, the levels of ROS, iron, MDA, and the protein expression of NCOA4, as well as the LC3B Ⅱ/Ⅰ ratio were increased (P<0.01), the SOD level, and the protein expression of FTH1 and GPX4 were decreased (P<0.01). Compared with the model group, in the electroacupuncture group, the escape latency was shortened and the number of platform crossings was increased (P<0.01), the RI was increased (P<0.01); the hippocampal neurons exhibited more regular morphology, better-organized cellular structure, and the number of Nissl bodies was increased (P<0.05); the percentage of iron deposition area in the hippocampus reduced (P<0.01); in the hippocampus, the levels of ROS, iron, MDA, and the protein expression of NCOA4, as well as the LC3B Ⅱ/Ⅰ ratio were decreased (P<0.01, P<0.05), the SOD level, and the protein expression of FTH1 and GPX4 were increased (P<0.01).
CONCLUSION
Electroacupuncture at "Sishencong" (EX-HN1) and "Fengchi" (GB20) can improve learning and memory abilities in VD rats, and its mechanism may be associated with the regulation of the hippocampal NCOA4/FTH1 signaling pathway, inhibition of ferritinophagy, and alleviation of oxidative stress damage.

BACKGROUND:
Durvalumab after chemoradiotherapy (CRT) failed to bring survival benefits to patients with epidermal growth factor receptor ( EGFR ) mutations in PACIFIC study (evaluating durvalumab in patients with stage III, unresectable NSCLC who did not have disease progression after concurrent chemoradiotherapy). We aimed to explore whether locally advanced inoperable patients with EGFR mutations benefit from tyrosine kinase inhibitors (TKIs) and the optimal treatment regimen.
METHODS:
We searched the PubMed, Embase, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases from inception to December 31, 2022 and performed a meta-analysis based on a Bayesian framework, with progression-free survival (PFS) and overall survival (OS) as the primary endpoints.
RESULTS:
A total of 1156 patients were identified in 16 studies that included 6 treatment measures, including CRT, CRT followed by durvalumab (CRT-Durva), TKI monotherapy, radiotherapy combined with TKI (RT-TKI), CRT combined with TKI (CRT-TKI), and TKI combined with durvalumab (TKI-Durva). The PFS of patients treated with TKI-containing regimens was significantly longer than that of patients treated with TKI-free regimens (hazard ratio [HR] = 0.37, 95% confidence interval [CI], 0.20-0.66). The PFS of TKI monotherapy was significantly longer than that of CRT (HR = 0.66, 95% CI, 0.50-0.87) but shorter than RT-TKI (HR = 1.78, 95% CI, 1.17-2.67). Furthermore, the PFS of RT-TKI or CRT-TKI were both significantly longer than that of CRT or CRT-Durva. RT-TKI ranked first in the Bayesian ranking, with the longest OS (60.8 months, 95% CI = 37.2-84.3 months) and the longest PFS (21.5 months, 95% CI, 15.4-27.5 months) in integrated analysis.
CONCLUSIONS:
For unresectable stage III EGFR mutant NSCLC, RT and TKI are both essential. Based on the current evidence, RT-TKI brings a superior survival advantage, while CRT-TKI needs further estimation. Large randomized clinical trials are urgently needed to explore the appropriate application sequences of TKI, radiotherapy, and chemotherapy.

BACKGROUND:
Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited.
METHODS:
This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed.
RESULTS:
Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P = 0.021) and transitioning to plaque psoriasis ( P = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP.
CONCLUSIONS
The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

This study aims to explore the protective effect of Chaihu Jia Longgu Muli Decoction on rats with heart failure after myocardial infarction, and to clarify its possible mechanisms, providing a new basis for basic research on the mechanism of classic Chinese medicinal formula-mediated inflammatory response in preventing and treating heart failure induced by apoptosis after myocardial infarction. A heart failure model after myocardial infarction was established in rats by coronary artery ligation. The rats were divided into sham group, model group, and low, medium, and high-dose groups of Chaihu Jia Longgu Muli Decoction, with 10 rats in each group. The low-dose, medium-dose, and high-dose groups of Chaihu Jia Longgu Muli Decoction were given 6.3, 12.6, and 25.2 g·kg~(-1) doses by gavage, respectively. The sham group and model group were given an equal volume of distilled water by gavage once daily for four consecutive weeks. Cardiac function was assessed using color Doppler echocardiography. Myocardial pathology was detected by hematoxylin-eosin(HE) staining, apoptosis was measured by TUNEL assay, and mitophagy was observed by transmission electron microscopy. The levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-1β, and N-terminal pro-B-type natriuretic peptide(NT-proBNP) in serum were detected by enzyme-linked immunosorbent assay(ELISA). The expression of apoptosis-related proteins B-cell lymphoma 2(Bcl-2), Bcl-2-associated X protein(Bax), and cleaved caspase-3 was detected by Western blot. Additionally, the expression of phosphorylated nuclear transcription factor-κB(NF-κB) p65(p-NF-κB p65)(upstream) and nuclear factor kappa B inhibitor alpha(IκBα)(downstream) in the NF-κB signaling pathway was assessed by Western blot. The results showed that compared with the sham group, left ventricular ejection fraction(LVEF) and left ventricular short axis shortening(LVFS) in the model group were significantly reduced, while left ventricular end diastolic diameter(LVEDD) and left ventricular end systolic diameter(LVESD) increased significantly. Myocardial tissue damage was severe, with widened intercellular spaces and disorganized cell arrangement. The apoptosis rate was increased, and mitochondria were enlarged with increased vacuoles. Levels of TNF-α, IL-1β, and NT-proBNP were elevated, indicating an obvious inflammatory response. The expression of pro-apoptotic factors Bax and cleaved caspase-3 increased, while the anti-apoptotic factor Bcl-2 decreased. The expression of p-NF-κB p65 was upregulated, and the expression of IκBα was downregulated. In contrast, the Chaihu Jia Longgu Muli Decoction groups showed significantly improved of LVEF, LVFS and decreased LVEDD, LVESD compared to the model group. Myocardial tissue damage was alleviated, and intercellular spaces were reduced. The apoptosis rate decreased, mitochondrial volume decreased, and the levels of TNF-α, IL-1β, and NT-proBNP were lower. The expression of pro-apoptotic factors Bax and cleaved caspase-3 decreased, while the expression of the anti-apoptotic factor Bcl-2 increased. Additionally, the expression of p-NF-κB p65 decreased, while IκBα expression increased. In summary, this experimental study shows that Chaihu Jia Longgu Muli Decoction can reduce the inflammatory response and apoptosis rate in rats with heart failure after myocardial infarction, which may be related to the regulation of the IκBα/NF-κB signaling pathway.
