ObjectiveTo observe the activation patterns and functional connectivity in the prefrontal cortex of patients with post-stroke anxiety (PSA) using functional near-infrared spectroscopy, in order to explore the underlying neural mechanism. MethodsFrom December, 2024 to September, 2025, 120 stroke patients were selected in Changzhou De'an Hospital. They were divided into PSA group (n = 60) and non-PSA group (n = 60) according to the score of Hamilton Anxiety Scale (HAMA). All patients wore an 18-channel fNIRS acquisition cap for detection. The differences in resting-state functional connectivity between the frontopolar cortex (FPC) and dorsolateral prefrontal cortex (DLPFC) were examined in both groups, as well as task-related activation in these brain regions. ResultsResting-state functional connectivity analysis revealed no statistically significant difference in network connectivity between two groups in the FPC and DLPFC regions (|t| < 1.301, P > 0.05). Task-related activation results revealed significantly reduced activation in the contralateral FPC of PSA group compared to the non-PSA group (Z = -2.063, P < 0.05). Activation levels in this region showed a negative correlation with the scores of HAMA (ρ = -0.201, P = 0.028). ConclusionActivation decreased in the contralateral frontal pole during the task state for patients with PSA, and the activation levels negatively correlates with anxiety severities.

Objective:To explore the effect of combining transcranial magnetic stimulation (rTMS) with acupuncture in the treatment of patients with vascular cognitive impairment (VCI).Methods:A total of 40 VCI patients were randomly assigned to either the control group or the experimental group ( n=20 per group) using a random number table. Both groups received routine treatment and rTMS, while the experimental group was additionally provided with acupuncture for four weeks. The rTMS was at 10Hz at 90% of the motor threshold. Before and after the treatment, both groups′ cognition was evaluated using the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE). Ability in the activities of daily living (ADL) was quantified using the modified Barthel Index (MBI). Serum levels of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) were measured using enzyme-linked immunosorbent assays. Results:Significant improvement was observed in both groups′ average MoCA, MMSE, and MBI scores, along with reductions in peripheral serum IL-6 and TNF-α levels. The experimental group exhibited significantly higher MoCA subdomain scores in the visuospatial and executive function, attention, and delayed recall subdomains, as well as a higher total MoCA score compared to the control group. The average MMSE and MBI scores were significantly higher in the experimental group than the control group, and that group′s serum IL-6 and TNF-α levels were significantly lower, on average. Pearson correlation analysis demonstrated a positive correlation between the improvements in MoCA and MMSE scores and the reductions in IL-6 and TNF-α levels in both groups.Conclusions:rTMS combined with acupuncture effectively improves cognition and ADL ability among VCI patients. The underlying mechanism may be associated with the reduction of neuroinflammatory factors IL-6 and TNF-α.

Objective:To investigate the gene expression of pulmonary metastatic papillary thyroid cancer (PTC) and its association with lung metastasis, facilitating risk assessment and personalized therapeutic strategies.Methods:A retrospective cohort study was conducted on 269 PTC patients (61 males, 208 females, age (38.9±11.9) years) treated at the Affiliated Cancer Hospital of Xiangya School of Medicine, Central South University from January 2017 to June 2020, including 60 cases with lung metastasis and 209 without. Primary tumor tissues underwent targeted next-generation sequencing (tNGS). Univariate and multivariate logistic regression analyses were performed to identify risk factors for lung metastasis, and χ2 test was used to evaluate the differences between the effective and ineffective groups of radioactive iodine (RAI) therapy. Results:In 60 PTC patients with lung metastasis, the mutation rates of B-Raf proto-oncogene, serine/threonine protein kinase (BRAF) V600E, telomerase reverse transcriptase (TERT) promoter, and rearranged in transformation (RET) fusion mutations were 28.3%(17/60), 25.0%(15/60), and 26.7%(16/60), respectively. Univariate analysis demonstrated that age≥55 years, multifocality, lateral cervical lymph node metastasis, extrathyroidal extension, BRAF V600E mutation, RET fusion, and TERT promoter mutation were significantly associated with lung metastasis in PTC ( Wald χ2 values: 4.13-31.28, all P<0.05). However, no significant statistical associations were observed between lung metastasis and gender, rat sarcoma type GTPase family (RAS) mutation, tumor protein p53 (TP53) mutation, phosphatidylinositol-4, 5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) mutation, neurotrophic tyrosine receptor kinase 1 (NTRK1) fusion, or anaplastic lymphoma kinase (ALK) fusion ( Wald χ2 values: 0.01-3.50, all P>0.05). Multivariate analysis identified TERT promoter mutation (odds ratio ( OR)=11.86, 95% CI: 3.68-38.29, P<0.001), multifocality ( OR=5.30, 95% CI: 2.41-11.69, P<0.001), extrathyroidal extension ( OR=3.98, 95% CI: 1.77-8.98, P=0.001), and lateral cervical lymph node metastasis ( OR=3.13, 95% CI: 1.28-7.68, P=0.013) as independent risk factors for lung metastasis in PTC. Conversely, BRAF V600E mutation emerged as a potential protective factor ( OR=0.09, 95% CI: 0.04-0.21, P<0.001). The proportions of BRAF V600E mutation ( χ2=20.49, P<0.001) and TERT promoter mutation ( χ2=4.91, P=0.027) were higher in the RAI ineffective group. Conclusions:BRAF V600E mutation, TERT promoter mutation and RET fusion are related gene expression in lung metastasis of PTC. Multifocality, extrathyroidal extension, lateral cervical lymph node metastasis and TERT promoter mutation are risk factors for lung metastasis of PTC (TERT is an independent molecular risk marker), while BRAF V600E mutation may be a protective factor. RAI treatment efficacy of PTC patients with lung metastasis and BRAF V600E mutation/TERT promoter mutation is worse.

Objective To understand the molecular epidemiological characteristics and hypervirulence evolution trend of ST11 carbapenem-resistant Klebsiella pneumoniae(CRKP)isolated from medical institutions in Shanghai,and provide scientific basis for formulating the prevention and control measures of drug-resistant organisms.Methods A total of 201 strains of CRKP isolated from 12 medical institutions in Shanghai from 2021 to 2022 were collected.Antimicrobial susceptibility testing and whole genome sequencing were performed.The concatenated data was used for multilocus sequencing typing(MLST),serum typing(wzi typing),as well as analysis of resistance and viru-lence genes.Results All 201 CRKP strains were multidrug-resistant organisms(MDROs).These strains were al-most completely resistant to carbapenems,cephalosporins,and quinolones.Drug resistance gene analysis showed that 93.03％of CRKP strains carried KPC gene.201 CRKP strains were divided into 6 ST types and 10 capsule wzi types,with ST11-KL64(n=104)being the dominant type,followed by ST15-KL19(n=54).52.24％(n=105)of CRKP carried rpmA/rpmA2+iucA+iutA+iroN genes.Conclusion CRKP isolated from medical institutions in Shanghai is mainly ST11-KL64 type with severe multidrug resistance,and more than half of the strains are hyper-virulent carbapenem-resistant Klebsiella pneumoniae(hv-CRKP).It is necessary to continuously strengthen the monitoring of the molecular characteristics of CRKP,so as to prevent outbreaks of healthcare-associated infection.

Ulcerative colitis （UC）， a chronic， non-specific inflammatory bowel disease with typical symptoms such as abdominal pain， diarrhea， and bloody stools， demonstrates a high relapse rate and difficulty in curing. Sishenwan， first recorded in Internal Medicine Abstract （Nei Ke Zhai Yao）， are a classic prescription for treating diarrhea caused by deficiency of the spleen and kidney Yang. The core therapeutic principle of Sishenwan is warming and tonifying the spleen and kidney， and astringing the intestine and stopping diarrhea. In recent years， Sishenwan have demonstrated distinct advantages in the clinical treatment of UC. The pathogenesis of UC involves multiple factors， including immune dysregulation and gut microbiota imbalance. Although Western medicine is effective in the short term， its side effects， high relapse rate， and resistance associated with long-term use pose substantial challenges. Sishenwan have shown excellent clinical outcomes in the treatment of UC due to deficiency of the spleen and kidney Yang. Modern clinical studies indicate that Sishenwan， used alone or in combination with Western medicine or other Chinese medicine compound prescriptions， significantly improve the clinical efficacy in treating UC due to deficiency of the spleen and kidney Yang. Sishenwan effectively alleviate core symptoms such as mucus， pus， and blood in stools， and persistent abdominal pain， reduce Mayo scores and the relapse rate， and improve patients' quality of life. Research on the material basis reveals that Sishenwan contain multiple active ingredients such as psoralen， isopsoralen， and evodiamine. Mechanism studies indicate that Sishenwan inhibit the inflammatory cascade reactions by regulating the signal network through multiple targets. Sishenwan regulate cellular immunity and restore intestinal immune homeostasis. At the microecological level， Sishenwan promote the intestinal barrier repair through the "microbiota-metabolism-immunity" axis. The current research still needs to be deepened in aspects such as the mining of specific biomarkers for syndromes and the exploration of the collaborative mechanism of traditional Chinese and Western medicine. In the future， a full-chain system covering syndrome differentiation， targeting， and monitoring needs to be constructed for promoting the paradigm transformation of Sishenwan into precision drugs. This review systematically explains the treatment mechanism of Sishenwan regarding the combination of disease and syndrome and its multi-target regulatory characteristics， providing a theoretical basis and transformation direction for the treatment of UC with integrated traditional Chinese and Western medicine.
