Objective:
To compare the effects of seasonal autoregressive integrated moving average (SARIMA) , seasonal autoregressive integrated moving average with exogenous regressors (SARIMAX) and long short-term memory neural network (LSTM) models in predicting the incidence of hand, foot, and mouth disease (HFMD).
Methods:
Monthly incidence data of HFMD in Kunming City from 2010 to 2019 were collected. SARIMA, SARIMAX and LSTM models were established using the monthly incidence of HFMD from 2010 to 2018 to predict the monthly incidence of HFMD from January to December 2019. The prediction performance of the three models was compared using mean squared error (MSE), root mean squared error (RMSE), mean absolute error (MAE) and mean absolute percentage error (MAPE). The optimal prediction model was selected based on the principle of minimizing MSE, RMSE, MAE and MAPE.
Results:
The HFMD cases were reported every month in Kunming City from 2010 to 2019, with the incidence fluctuating between 188.27/105 and 363.15/105. The disease exhibited a biennial high-incidence bimodal distribution. Among the four evaluation indicators for the training and testing sets, the LSTM model had the smaller values: MSE was 63.182 and 102.745, RMSE was 7.949 and 10.136, MAE was 6.535 and 7.620, and MAPE was 46.726% and 31.138%. The LSTM model performed the better, followed by the SARIMA model, while the SARIMAX model had the relatively poorest performance.
Conclusion
The LSTM model outperforms the SARIMA and SARIMAX models in predicting the incidence of HFMD.

BackgroundGraduate students frequently face life events, many of which may adversely affect their mental well-being. However, the interaction between life events and the development of depression, anxiety, and somatic symptoms remains unclear. ObjectiveTo explore the relationship between life events and the development of depressive, anxiety and somatic symptoms in graduate students, thereby informing prevention strategies for these conditions. MethodsA sample of 6 722 newly enrolled graduate students at a comprehensive university in Southwest China from September to November 2018 was selected. The assessment was conducted using the Adolescent Self-rating Life Events Checklist (ASLEC), the 7-item Generalized Anxiety Disorder scale-7 item (GAD-7), the Patient Health Questionnaire Depression Scale-9 item (PHQ-9), and the Patient Health Questionnaire-15 (PHQ-15). Network analysis was implemented by using the bootnet and qgraph packages in the R software (version 4.2.3), with centrality indices calculated to identify core and bridge symptoms within the network. ResultsThe study encompassed a total of 6 171 graduate students, representing 91.80% of the target population. The prevalence rates of anxiety, depressive, and somatic symptoms among graduate students were 12.59% (777/6 171), 16.63% (1 026/6 171), and 27.66% (1 707/6 171), respectively. Network analysis revealed that 'academic stress' was the core symptom with the highest strength and expected influence (both values=1.207), while 'feeling down, depressed, or hopeless' was the bridge symptom with the highest bridge strength and bridge expected influence (both values=0.454). There was no significant difference in global network strength and edge weight between women and men (P>0.05). ConclusionAcademic stress, emerging as the core symptom, assumes a dominant position within the symptom network and exhibits strong interactions with other negative affective states. There was no gender difference in the network structure.

BackgroundThe occurrence rate of dangerous behaviors in patients with severe mental disorders is higher than that of the general population. In China, there is limited research on the prediction of dangerous behaviors in community-dwelling patients with severe mental disorders, particularly in terms of predicting models using data mining techniques other than traditional methods. ObjectiveTo explore the influencing factors of dangerous behaviors in community-dwelling patients with severe mental disorders and testing whether the classification decision tree model is superior to the Logistic regression model. MethodsA total of 11 484 community-dwelling patients with severe mental disorders who had complete follow-up records from 2013 to 2022 were selected on December 2023. The data were divided into a training set (n=9 186) and a testing set (n=2 298) in an 8∶2 ratio. Logistic regression and classification decision trees were separately used to establish predictive models in the training set. Model discrimination and calibration were evaluated in the testing set. ResultsDuring the follow-up period, 1 115 cases (9.71%) exhibited dangerous behaviors. Logistic regression results showed that urban residence, poverty, guardianship, intellectual disability, history of dangerous behaviors, impaired insight and positive symptoms were risk factors for dangerous behaviors (OR=1.778, 1.459, 2.719, 1.483, 3.890, 1.423, 2.528, 2.124, P<0.01). Being aged ≥60 years, educated, not requiring prescribed medication and having normal social functioning were protective factors for dangerous behaviors (OR=0.594, 0.824, 0.422, 0.719, P<0.05 or 0.01). The predictive effect in the testing set showed an area under curve (AUC) of 0.729 (95% CI: 0.692~0.766), accuracy of 70.97%, sensitivity of 59.71%, and specificity of 72.05%. The classification decision tree results showed that past dangerous situations, positive symptoms, overall social functioning score, economic status, insight, household registration, disability status and age were the influencing factors for dangerous behaviors. The predictive effect in the testing set showed an AUC of 0.721 (95% CI: 0.705~0.737), accuracy of 68.28%, sensitivity of 64.46%, and specificity of 68.60%. ConclusionThe classification decision tree does not have a greater advantage over the logistic regression model in predicting the risk of dangerous behaviors in patients with severe mental disorders in the community.

The aim is to evaluate the effect of therapeutic communication on cervical cancer patients’ preoperative anxiety and hope level. The convenience sampling method was used to select the inpatients who will receive radical surgery for cervical cancer in the department of obstetrics and gynecology of the Second Affiliated Hospital of Xi’an Jiaotong University from November 2016 to November 2019 as the research object. 50 patients were grouped by the random number table method: 25 patients were in the intervention group, and 25 patients were in the control group. Patients in the intervention group were given therapeutic communication on the basis of routine nursing, and patients in the control group were given routine nursing. Both groups were investigated with the Self-Rating Anxiety Scale (SAS) and Herth Hope Index (HHI) on the first day of admission and the day before surgery. Before the intervention, there was no statistically significant difference between the two groups (P>0.05) . After the intervention, the anxiety level of the intervention group was lower than that of the control group (P<0.05), and the hope level was higher than that of the control group (P<0.05). It can be seen that therapeutic communication can alleviate preoperative anxiety of cervical cancer patients, improve their hope level, promote patient recovery, and ease tense medical relationship.

ObjectiveThe active ingredients, action targets, and signaling pathways of Cuscutae Semen to control premature ovarian failure were initially predicted by network pharmacology and molecular docking techniques, and an animal model of premature ovarian failure was constructed to explore the mechanism of Cuscutae Semen based on lipid and atherosclerosis signaling pathways. MethodThe effective components and corresponding targets of drugs were obtained from Traditional Chinese Medicines Systems Pharmacology Platform (TCMSP), Swiss Target Prediction, Pharmmapper, and other databases. GeneCards database was used to collect disease-related targets. Venny2.1.0 online tool was used to screen out the intersection targets of drugs and diseases, and STRING database and Cytoscape v3.7.2 software were used to construct the network diagram of "drug-component-target" and protein-protein interaction (PPI). The gene ontology (GO) and the Kyoto encyclopedia of genes and genomes (KEGG) enrichment analyses of the intersection targets were performed by running the R language script. The molecular docking technology was utilized to dock drug components with targets and visualize some of the docking results. The mice were randomly divided into a blank group, a model group, a Cuscutae Semen group, and an estradiol valerate group, and the ovarian premature failure model was prepared by chronic stress. The blank group and the model group were gavaged with the same amount of normal saline, and the Cuscutae Semen group was given a Cuscutae Semen decoction of 2.6 g·kg-1·d-1. The estradiol valerate group was given an estradiol valerate solution of 0.13 mg·kg-1·d-1. After four weeks, samples were collected, and hematoxylin-eosin (HE) staining was performed to observe the histopathological changes in the ovary. Serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), Muller's tube inhibitor/anti-Muller's tube hormone (AMH), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were determined by enzyme-linked immunosorbent assay (ELISA). The expression levels of extracellular regulatory protein kinase (ERK), nuclear transcription factor-κB p65 (NF-κB p65), nuclear transcription factor-κB suppressor α (IκBα), interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α) were measured by Western blot. ResultA total of 171 targets of Cuscutae Semen for the prevention and treatment of premature ovarian failure were screened, mainly including tumor protein p53 (TP53), protein kinase B1 (Akt1), sarcoma (SRC), tumor necrosis factor (TNF), epidermal growth factor receptor (EGFR), etc. KEGG pathway enrichment analysis predicts that Cuscutae Semen is mainly involved in lipid and atherosclerosis, TNF signaling pathway, and TP53 signaling pathway to control premature ovarian failure. The animal experiments show that compared with the premature ovarian failure model group, the Cuscutae Semen group can significantly upregulate AMH, E2, and HDL-C (P<0.05, P<0.01), significantly downregulate LH, TC, and LDL-C (P<0.01), greatly reduce IL-1β, IL-6, and TNF-α protein levels, as well as ERK, NF-κB p65, and their phosphorylation levels (P<0.01). ConclusionCuscutae Semen can regulate hormone levels and improve ovarian function through a multi-component, multi-target, and multi-pathway approach, and the mechanism may be related to the regulation of lipid and atherosclerosis signaling pathways.

ObjectiveTo investigate the role and mechanism of DNA repair regulation in the process of hepatocellular carcinoma (HCC) recurrence. MethodsHCC tissue samples were collected from the patients with recurrence within two years or the patients with a good prognosis after 5 years, and the Tandem Mass Tag-labeled quantification proteomic study was used to analyze the differentially expressed proteins enriched in the four pathways of DNA replication, mismatch repair, base excision repair, and nucleotide excision repair, and the regulatory pathways and targets that play a key role in the process of HCC recurrence were analyzed to predict the possible regulatory mechanisms. The independent samples t-test was used for comparison of continuous data between two groups; a one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsFor the eukaryotic replication complex pathway, there were significant reductions in the protein expression levels of MCM2 (P=0.018), MCM3 (P=0.047), MCM4 (P=0.014), MCM5 (P=0.008), MCM6 (P=0.006), MCM7 (P=0.007), PCNA (P=0.019), RFC4 (P=0.002), RFC5 (P<0.001), and LIG1 (P=0.042); for the nucleotide excision repair pathway, there were significant reductions in the protein expression levels of PCNA (P=0.019), RFC4 (P=0.002), RFC5 (P<0.001), and LIG1 (P=0.042); for the base excision repair pathway, there were significant reductions in the protein expression levels of PCNA (P=0.019) and LIG1 (P=0.042) in the HCC recurrence group; for the mismatch repair pathway, there were significant reductions in the protein expression levels of MSH2 (P=0.026), MSH6 (P=0.006), RFC4 (P=0.002), RFC5 (P<0.001), PCNA (P=0.019), and LIG1 (P=0.042) in recurrent HCC tissue. The differentially expressed proteins were involved in the important components of MCM complex, DNA polymerase complex, ligase LIG1, long patch base shear repair complex (long patch BER), and DNA mismatch repair protein complex. The clinical sample validation analysis of important differentially expressed proteins regulated by DNA repair showed that except for MCM6 with a trend of reduction, the recurrence group also had significant reductions in the relative protein expression levels of MCM5 (P=0.008), MCM7 (P=0.007), RCF4 (P=0.002), RCF5 (P<0.001), and MSH6 (P=0.006). ConclusionThere are significant reductions or deletions of multiple complex protein components in the process of DNA repair during HCC recurrence.

Objective:Trigeminal neuralgia(TN)is a severe chronic neuropathic pain that mainly affects the distribution area of the trigeminal nerve with limited treating efficacy.There are numerous treatments for TN,but currently the main clinical approach is to suppress pain by carbamazepine(CBZ).Brain-derived neurotrophic factor(BDNF)is closely related to chronic pain.This study aims to determine the effects of CBZ treatment on BDNF expression in both the trigeminal ganglion(TG)and serum of TN via a chronic constriction injury of the infraorbital nerve(ION-CCI)rat model. Methods:The ION-CCI models were established in male Sprague-Dawley rats and were randomly divided into a sham group,a TN group,a TN+low-dose CBZ treatment group(TN+20 mg/kg CBZ group),a TN+medium-dose CBZ treatment group(TN+40 mg/kg CBZ group),and a TN+high-dose CBZ treatment group(TN+80 mg/kg CBZ group).The mechanical pain threshold in each group of rats was measured regularly before and after surgery.The expressions of BDNF and tyrosine kinase receptor B(TrkB)mRNA in TGs of rats in different groups were determined by real-time PCR,and the expression of BDNF protein on neurons in TGs was observed by immunofluorescence.Western Blotting was used to detect the protein expression of BDNF,TrkB,extracellular regulated protein kinases(ERK),and phospho-extracellular regulated protein kinases(p-ERK)in TGs of rats in different groups.The expression of BDNF in the serum of rats in different groups was detected by enzyme-linked immunosorbent assay(ELISA). Results:The results of mechanical pain sensitivity showed that there was no significant difference in the mechanical pain threshold in the right facial sensory area of the experimental rats in each group before surgery(all P>0.05).From the 3rd day after operation,the mechanical pain threshold of rats in the TN group was significantly lower than that in the sham group(all P<0.01),and the mechanical pain threshold of rats in the TN+80 mg/kg CBZ group,the TN+40 mg/kg CBZ group,and the TN+20 CBZ mg/kg group was higher than that in the TN group(all P<0.05).The BDNF and TrkB mRNA and protein expressions in TGs of rats in the TN group were higher than those in the sham group(all P<0.05),and those in the TN+80 mg/kg CBZ group,the TN+40 mg/kg CBZ group,and the TN+20 mg/kg CBZ group were lower than the TN group(all P<0.05).The p-ERK levels in TG of rats in the TN+80 mg/kg CBZ group,the TN+40 mg/kg CBZ group,and the TN+20 mg/kg CBZ group were significantly decreased compared with the TN group(all P<0.05).The BDNF and neuron-specific nuclear protein(NeuN)were mainly co-expressed in neuron of TGs in the TN group and they were significantly higher than those in the sham group(all P<0.05).The co-labeled expressions of BDNF and NeuN in TGs of the TN+ 80 mg/kg CBZ group,the TN+40 mg/kg CBZ group,and the TN+20 mg/kg CBZ group were lower than those in the TN group(all P<0.05).The results of ELISA showed that the level of BDNF in the serum of the TN group was significantly higher than that in the sham group(P<0.05).The levels of BDNF in the TN+80 mg/kg CBZ group,the TN+40 mg/kg CBZ group,and the TN+20 mg/kg CBZ group were lower than those in the TN group(all P<0.05).Spearman correlation analysis showed that the BDNF level in serum was negatively correlated with mechanical pain threshold(r=-0.650,P<0.01). Conclusion:CBZ treatment can inhibit the expression of BDNF and TrkB in the TGs of TN rats,reduce the level of BDNF in serum of TN rats and the phosphorylation of ERK signaling pathway,so as to inhibit TN.The serum level of BDNF can be considered as an indicator for the diagnosis and prognosis of TN.

Objective:To observe the effect of point application-invigorate the spleen and kidney, circulation of blood formula (PA) combined with five-animal exercise (FAE) on improving the nutritional status for asthenia of patients with dialysis, and provide evidence for the rehabilitation treatment of dialysis patients.Methods:According to the random number table method, a total of 80 patients treated with regular dialysis at Department of Nephrology, the Affiliated Hospital of Nanjing University of Chinese Medicine from April 2020 to December 2021 were randomly divided into experimental group and control group, with 40 cases in each group. Participants in the control group received regular dialysis, basic treatment and diet nursing (RBD). Participants in the experimental group received RBD plus PA+FAE. Labaratory test results, Subjective Global Assessment scale score and Traditional Chinese medicine symptom score were measured at baseline and 12-weeks after the intervention. The Fried Frailty scale score was measured at baseline, 4, 8, and 12 weeks after the intervention.Results:The control group aged (54.08 ± 11.34) years old, 23 males, 17 females; the experimental group aged (57.38±9.89) years old, 19 males, 21 females. After 4, 8 and 12 weeks of intervention, the Fried Frailty Scale scores of the experimental group at different time points were 2 (2, 2), 1 (1, 2) and 1 (0, 1), respectively, lower than 3 (2, 4), 2 (2, 3) and 2 (2, 3) of the control group, and the differences in time effect, inter-group effect and interaction effect were statistically significant ( F=105.76, 18.38, 46.67, all P<0.01). Further pairwise comparisons within groups indicated significant differences of Fried Frailty scale scores at different time points ( Z=-2.78, -4.01, -6.08, all P<0.01). After 12-week of intervention, the results of hemoglobin, serum albumin and serum prealbumin were (107.88 ± 15.58) g/L, (39.10 ± 4.92) g/L, and (289.36 ± 72.05) mg/L in the experimental group, respectively, higher than (100.15 ± 17.62) g/L, (36.93 ± 4.72) g/L, (255.63 ± 75.35) mg/L in the control group ( t=-2.08, -2.01, -2.05, all P<0.05). Subjective Overall Assessment scale was found a significant difference between the 2 groups ( χ2=10.91, P<0.01): the number of grade A (good nutrition) and B (mild to moderate malnutrition) were 36 and 4 in the experimental group and 23 and 17 in the control group. Traditional Chinese medicine symptom score was (4.68 ± 2.50) in the experimental group, lower than (9.58 ± 4.40) in the control group ( t=6.13, P<0.01). Conclusions:Point application-invigorate the spleen and kidney and circulation of blood formula combined with five-animal exercise can effectively improve the nutritional status of dialysis patients and reduce the weakness of patients
