Objective:
To investigate the epidemiological characteristics of pertussis in Jiaxing City from 2004 to 2023 and spatio-temporal clustering characteristics from 2022 to 2023, so as to provide insights into formulation of pertussis control measures.
Methods:
Data of pertussis cases in Jiaxing City from 2004 to 2023 were collected through the Infectious Disease Report Information System of Chinese Disease Prevention and Control Information System. The epidemiological characteristics of pertussis cases in Jiaxing City from 2004 to 2023 were descriptively analyzed, and the spatio-temporal clustering characteristics from 2022 to 2023 were analyzed using spatio-temporal scanning.
Results:
A total of 478 pertussis cases were reported in Jiaxing City from 2004 to 2023, with an average annual reported incidence of 0.53/105. The reported incidence showed an upward trend from 2004 to 2023 (P<0.05), with the highest in 2022 (3.17/105). Higher incidence of pertussis was reported in June to August (149 cases, 31.17%) and November to December (112 cases, 23.43%). There was no statistically significant difference in the reported incidence between males and females (0.56/105 vs. 0.50/105, P>0.05). The cases aged under one year accounted for the highest proportion, with 199 cases (41.63%). Haining City (0.68/105), Jiashan County (0.64/105) and Tongxiang City (0.60/105) ranked the top three in the reported incidence of pertussis. Spatio-temporal scanning analysis showed that from 2022 to 2023, the primary clustering area of pertussis was centered in Daqiao Town of Nanhu District, covering 27 towns (streets) in Nanhu District, Jiashan County, Xiuzhou District and Pinghu City, and the clustering time was from November to December, 2023.
Conclusions
The reported incidence of pertussis was at a low level in Jiaxing City, but showed an upward trend from 2004 to 2023. The incidence of pertussis was higher among infants under one year of age, peaked in June to August and November to December, and was concentrated in Nanhu District and its surrounding areas.

OBJECTIVE To provide direction and reference for the adjustment of the discount rate (DR) in China’s pharmacoeconomic guidelines. METHODS Search was conducted on the official websites of the International Society for Pharmacoeconomics and Outcomes Research, health technology assessment agencies in various countries/regions, as well as relevant websites of other upper-middle-income or high-income countries/regions. The recommended DR, adjustment trends, and setting rationales in pharmacoeconomic evaluation guidelines across different countries/regions were then summarized and compared. Based on theoretical derivation and literature analysis, the effects of different DR on the incremental cost-effectiveness ratio (ICER) were examined. RESULTS & CONCLUSIONS Among the 40 included guidelines, the base-case DR ranged from 1.5% to 5%, with 5% being the most common value; the range for sensitivity analysis was 0 to 12%. Thirty-six countries/regions applied the same DR to both costs and health outcomes, while in the Netherlands, Belgium, Poland and Czech Republic, DR for costs was higher than for health outcomes. In recent years, Korea, France and Ireland had lowered their DR in response to economic changes, whereas the Netherlands and Czech Republic had raised their DR for cost. The setting of the DR was primarily based on the public project investment interest rate or referred to recommendations from internationally authoritative institutions and other relevant guidelines. The direction and magnitude of the impact of different DR on the ICER largely depended on the distribution of costs and health outcomes between the intervention and reference measure. The setting and adjustment of DR were closely associated with the economic environment. Based on international experience, the DR in China can be lowered by 0.5% to 1.5%, and localized empirical research can be conducted using internationally common estimation methods.

Ischemia-reperfusion (I/R) injury following skin flap transplantation is a critical factor leading to flap necrosis and transplant failure. Antagonizing inflammatory responses and oxidative stress are regarded as crucial targets for mitigating reperfusion injury and enhancing flap survival. In this study, caffeic acid-vanadium metal polyphenol nanoparticles (CA-V NPs) were prepared for the treatment of skin flap ischemia and reperfusion. This study was conducted using a one-step method to prepare new types of CA-V NPs with uniform sizes and stable structures. In vitro, the CA-V NPs exhibited CAT-like and SOD-like activities and could effectively scavenge ROS, generate oxygen, and alleviate oxidative stress. In the H2O2-induced cellular oxidative stress model, CA-V NPs effectively reduced ROS levels and inhibited apoptosis through the XIAP/Caspase-3 pathway. In the cellular inflammation model induced by LPS combined with IFN-γ, CA-V NPs reprogrammed macrophage polarization toward the M2 phenotype and reduced inflammatory responses by reducing the expression of the chemokines CCL4 and CXCL2. In addition, animal experiments have shown that CA-V NPs can alleviate oxidative stress in skin flap tissues, inhibit apoptosis, promote angiogenesis, and ultimately improve the survival rate of skin flaps. CA-V NPs provide a new target and strategy for the treatment of flap I/R injury.

Ferroptosis is a form of programmed cell death characterized by overwhelmed lipid oxidation, and it has emerged as a promising strategy for cancer therapy. Enhanced ferroptosis could overcome the limitations of conventional therapeutic modalities, particularly in difficult-to-treat tumors. In this study, we developed a dual-modality therapy in nanomedicine by combining paclitaxel (PTX) chemotherapy and pyropheophorbide-a (Ppa) phototherapy. Heparin (HP) was grafted with poly(N-(2'-hydroxy) propyl methacrylamide) (pHPMA) using reversible addition-fragmentation chain transfer polymerization to form HP-pHPMA (HH), which was utilized to deliver Ppa and PTX, yielding HP-pHPMA-Ppa (HH-Ppa) and HP-pHPMA-PTX (HH-PTX), respectively. The prodrug-based combinational nanomedicine (HH-PP) was formed by co-assembly of HH-PTX and HH-Ppa. It was found that HH-PP treatment significantly disrupted lipid metabolism in triple-negative breast cancer (TNBC) cells, induced extensive lipid oxidation, and promoted ferroptosis. In vivo, HH-PP intervention achieved a tumor growth inhibition rate of 86.63% and activated adaptive immunity with an elevated CD8+ cytotoxic T cell infiltration level. This combinational nanomedicine offers a promising platform for co-delivery of multiple therapeutic agents. It exerts a promising anti-tumor effect via enhanced ferroptosis and ferroptosis-induced immune activation by disrupting lipid metabolism in TNBC cancer cells.

Approximately 30%-40% of epilepsy patients do not respond well to adequate anti-seizure medications (ASMs), a condition known as pharmacoresistant epilepsy. The management of pharmacoresistant epilepsy remains an intractable issue in the clinic. Its early prediction is important for prevention and diagnosis. However, it still lacks effective predictors and approaches. Here, a classical model of pharmacoresistant temporal lobe epilepsy (TLE) was established to screen pharmacoresistant and pharmaco-responsive individuals by applying phenytoin to amygdaloid-kindled rats. Ictal electroencephalograms (EEGs) recorded before phenytoin treatment were analyzed. Based on ictal EEGs from pharmacoresistant and pharmaco-responsive rats, a convolutional neural network predictive model was constructed to predict pharmacoresistance, and achieved 78% prediction accuracy. We further found the ictal EEGs from pharmacoresistant rats have a lower gamma-band power, which was verified in seizure EEGs from pharmacoresistant TLE patients. Prospectively, therapies targeting the subiculum in those predicted as "pharmacoresistant" individual rats significantly reduced the subsequent occurrence of pharmacoresistance. These results demonstrate a new methodology to predict whether TLE individuals become resistant to ASMs in a classic pharmacoresistant TLE model. This may be of translational importance for the precise management of pharmacoresistant TLE.

ObjectiveTo explore the possible mechanism of Bimin Formula (鼻敏方) in treating lung-spleen qi deficiency syndrome of allergic rhinitis (AR) with high mucin secretion. MethodsThirty-four SD rats were randomly divided into a blank group (8 rats), a model group (8 rats), a low-dose Bimin Formula group (8 rats), and a high-dose Bimin Formula group (10 rats). Except for the blank group, the other groups were subjected to AR lung-spleen qi deficiency rat models induced by smoking, gavage of Ginkgo biloba leaf extract, and ovalbumin. After modeling, rats in the low- and high-dose Bimin Formula groups were given Bimin Formula concentrate (concentration of 2.16 g/ml) by gavage at doses of 1.08 g/100 g and 2.16 g/100 g, respectively, while rats in the model group were given 0.5 ml/100 g of normal saline by gavage, once daily for 28 days; the blank group was not intervened. Behavioral assessments were performed after intervention. ELISA was used to detect the levels of peripheral blood total immunoglobulin E (IgE). HE staining was used to observe the pathological changes of nasal mucosa epithelium in rats, while immunohistochemistry was used to detect the expression of transmembrane protein 16A (TMEM16A) and mucin 5AC (MUC5AC) protein in nasal mucosa. Western Blot was used to detect the expression of nuclear factor kappa B (NF-κB) protein, and RT-PCR was used to detect the expression of TMEM16A, MUC5AC, and NF-κB mRNA in nasal mucosa. ResultsHE staining showed that the nasal mucosa epithelial cell structure in the blank group was intact without shedding, swelling, or necrosis; the nasal mucosa epithelial tissue of rats in the model group was thickened and partially shed, with infiltration of eosinophils and lymphocytes visible; the pathological changes in nasal mucosa tissue of rats in the high- and low-dose Bimin Formulagroups were improved, and more improvement was showen in the high-dose group. Compared with those in the blank group, the behavioral scores and peripheral blood total IgE levels of rats in the model group significantly increased, as well as the expression of TMEM16A, MUC5AC, and NF-κB proteins and mRNA in nasal mucosa (P<0.05 or P<0.01). Compared with those in the model group, the behavioral scores and peripheral blood total IgE levels of rats in the high-dose Bimin Formula group decreased, and the expression of TMEM16A, MUC5AC, and NF-κB proteins and mRNA in nasal mucosaalso decreased (P<0.05 or P<0.01); the behavioral scores and peripheral blood total IgE levels of rats in the low-dose Bimin Formula group were reduced, and the expression of TMEM16A and MUC5AC proteins and mRNA in nasal mucosa, as well as the expression of NF-κB protein decreased (P<0.05 or P<0.01), but the difference in NF-κB mRNA expression was not statistically significant (P>0.05). Compared with the low-dose Bimin Formula group, the expression of NF-κB protein in the high-dose group decreased (P<0.01). ConclusionBimin Formula may improve the symptoms and high mucus secretion of AR lung-spleen qi deficiency by regulating the TMEM16A/NF-κB/MUC5AC signaling pathway in nasalmucosa.
