Objective To explore scientific and accurate prediction methods for the incidence of hand, foot, and mouth disease in the post-pandemic era, and to address modeling challenges caused by abnormal fluctuations in case numbers from 2020 to 2023. Methods The seasonal index was used to pre-process the data. The traditional seasonal autoregressive integrated moving average (SARIMA) model, singular spectrum analysis (SSA)-ARIMA model, ARIMA-Long short-term memory (LSTM) model, and SSA-ARIMA-LSTM model were used to fit the incidence from 2013 to 2023, and the incidence of hand, foot and mouth disease in 2024 was predicted. The real data collected in 2024 were used as the test set to compare the prediction performance of the models. Results The fitting performance of the constructed models was as follows: the ARIMA model had MAE=107.50 and RMSE=144.53, the SSA-ARIMA model showed MAE=2.84 and RMSE=4.33, the ARIMA-LSTM model achieved MAE=99.46 and RMSE=131.59, and the SSA-ARIMA-LSTM model had MAE=96.35 and RMSE=132.13. In terms of prediction performance, the ARIMA model resulted in MAE=151.64 and RMSE=146.70, the SSA-ARIMA model demonstrated MAE=41.22 and RMSE=57.01, the ARIMA-LSTM model yielded MAE=220.75 and RMSE=257.89, and the SSA-ARIMA-LSTM model recorded MAE=58.83 and RMSE=72.06. Conclusion The SSA-ARIMA model has the best fitting degree and the highest prediction accuracy, and is suitable for predicting the incidence trend of hand, foot and mouth disease.

Journal of Apoplexy and Nervous Diseases 2025;42(2):109-114
Objective To investigate the clinical features of dyskinesia and related risk factors in female patients with Parkinson disease (PD). Methods A cross-sectional study was conducted among the female patients who met the diagnostic criteria for PD at the outpatient service of PD in Aerospace Center Hospital, and demographic data and clinical data were collected and compared between groups, including levodopa equivalent daily dose (LEDD), Unified Parkinson’s Disease Rating Scale-Ⅲ(UPDRS-Ⅲ), UPDRS-Ⅳ, scores of non-motor symptoms (cognition and depression), presence or absence of dyskinesia, and single levodopa dose (LD) during the onset of dyskinesia. A binary logistic regression analysis was used to investigate the influencing factors for dyskinesia in female patients with PD. Results A total of 146 female PD patients were enrolled, among whom 30 patients had dyskinesia, with an incidence rate of 20.5%. Compared with the non-dyskinesia group in terms of clinical features, the dyskinesia group had a significantly younger age of onset [(54.3±12.5) years vs (62.7±10.0) years, P<0.001], a significantly longer disease duration [(9.9±3.7) years vs (4.5±3.7) years, P<0.001], a significantly higher severity of disease [H-Y stage: (2.65±0.58) vs (2.35±0.83), P=0.03], a significantly longer duration of LD administration [(7.5±3.2) years vs (3.2±2.6) years, P<0.001], a significantly higher LEDD [(703.2±203.9) mg vs (442.1±226.3) mg, P<0.001], and significantly lower body weight [(54.1±8.2) kg vs (60.0±8.7) kg, P=0.001] and BMI [(20.9±3.1) kg/m2 vs (23.4±3.1) kg/m2, P<0.001]. The multivariate logistic regression analysis showed that high BMI (OR=0.770, P=0.005) was a protective factor against dyskinesia in female PD patients, while long disease duration (OR=1.304, P=0.001) and high LEDD (OR=1.003, P=0.012) were risk factors for dyskinesia. Conclusion There is a relatively high incidence rate of dyskinesia in female PD patients, which should be taken seriously in clinical practice, and high BMI is a protective factor, while long disease duration and high LEDD are risk factors for dyskinesia in female PD patients.

Although enteric glial cell (EGC) abnormal activation is reported to be involved in the pathogenesis of Parkinson's disease (PD), and inhibition of EGC gliosis alleviated gut and dopaminergic neuronal dysfunction was verified in our previous study, the potential role of gut microbiota on EGC function in PD still need to be addressed. In the present study, fecal microbiota transplantation revealed that EGC function was regulated by gut microbiota. By employing 16S rRNA and metabolomic analysis, we identified that 3-indolepropionic acid (IPA) was the most affected differential microbial metabolite that regulated EGC gliosis. The protective effects of IPA on PD were validated in rotenone-stimulated EGCs and rotenone (30 mg/kg i.g. for 4 weeks)-induced PD mice, as indicated by decreased inflammation, improved intestinal and brain barrier as well as dopaminergic neuronal function. Mechanistic study showed that IPA targeted pregnane X receptor (PXR) in EGCs, and inhibition of IL-13Rα1 involved cytokine-cytokine receptor interaction pathway, leading to inactivation of downstream JAK1-STAT6 pathway. Our data not only provided evidence that EGC gliosis was critical in spreading intestinal damage to brain, but also highlighted the potential role of microbial metabolite IPA in alleviating PD pathological damages through gut-brain axis.

Palmitoylation, an essential covalent attachment of a fatty acid (usually C16 palmitate) to cysteine residues within proteins, is crucial for regulating protein functionality and enzymatic activities. This lipid modification facilitates the anchoring of proteins to cellular membranes, dictating their subcellular distribution and influencing protein transport dynamics and intracellular positioning. Additionally, it plays a role in regulating protein degradation through the ubiquitin-proteasome system. Palmitoylation is implicated in the pathogenesis and progression of cardiovascular diseases by modulating substrates and prompting additional post-translational modifications, as well as by interacting with other molecular alterations. Moreover, an intervention strategy focusing on palmitoylation processes is anticipated to offer novel therapeutic avenues for cardiovascular pathologies and address extant challenges in clinical settings. This review consolidates current research on the role and importance of palmitoylation in cardiovascular diseases by exploring its regulatory functions, the catalyzing enzymes, and the involved substrates. It highlights recent discoveries connecting palmitoylation-targeted therapies to cardiovascular health and examines potential approaches and future challenges in cardiovascular treatment.

Objective:Differences between randomized controlled trial (RCT) results and real world study (RWS) results may not represent a true efficacy-effectiveness gap because efficacy-effectiveness gap estimates may be biased when RWS and RCT differ significantly in study design or when there is bias in RWS result estimation. Secondly, when there is an efficacy- effectiveness gap, it should not treat every patient the same way but assess the real-world factors influencing the intervention's effectiveness and identify the subgroup likely to achieve the desired effect.Methods:Six databases (PubMed, Embase, Web of Science, CNKI, Wanfang Data, and VIP) were searched up to 31 st December 2022 with detailed search strategies. A scoping review method was used to integrate and qualitatively describe the included literature inductively. Results:Ten articles were included to discuss how to use the RCT research protocol as a template to develop the corresponding RWS research protocol. Moreover, based on correctly estimating the efficacy-effectiveness gap, evaluate the intervention effect in the patient subgroup to confirm the subgroup that can achieve the expected benefit-risk ratio to bridge the efficacy-effectiveness gap.Conclusion:Using real-world data to simulate key features of randomized controlled clinical trial study design can improve the authenticity and effectiveness of study results and bridge the efficacy-effectiveness gap.
