Objective To establish a prediction model for the occurrence of non-occupational carbon monoxide poisoning events in Beijing, and to provide scientific basis and theoretical support for the prevention and warning of poisoning events. Methods Based on the monitoring data of non-occupational carbon monoxide poisoning events in Beijing from 2016 to 2024, the seasonal ARIMA model and seasonal index model were established to analyze the data and predict the occurrence of events. Results Between 2016 and 2024, a total of 436 cases of non-occupational carbon monoxide poisoning were reported in Beijing, showing a downward trend. The established SARIMA model and seasonal index model were SARIMA (1,0,0) (1,1,0) 12, Yt = (-0.0339t+5.8863) × St, and the average relative errors were 65.42% and 29.19%, respectively. In terms of months, the SARIMA model had better predictive performance during April and summer (June to August), while the seasonal index model was superior in other months. By combining the two models, the predicted number of events in 2025 was as follows: 3, 2, 2, 3, 1, 5, 2, 7, 1, 1, 1, and 2. Conclusion The seasonal index model has the best prediction effect on the non-occupational carbon monoxide poisoning events in Beijing throughout the year, and the number of summer events predicted by SARIMA model is closer to the actual values. The two models can be combined to predict the trend of non-occupational carbon monoxide poisoning, which provides a scientific basis for the prevention and control of carbon monoxide poisoning in the future.

Conclusion The current evidence shows that age, male, drinking history, diabetes history, operation time, DHCA time, aortic occlusion time, cardiopulmonary bypass time, ICU stay, hospital stay, APACHEⅡ score, ventilation support time, hypoxemia and postoperative body temperature are risk factors for the postoperative delirium after surgery for Stanford type A aortic dissection. Oxygenation index, oxygen saturation, and hemoglobin number are protective factors for delirium after Stanford type A aortic dissection.

Objective:To analyze the temporal distribution characteristics of hand, foot and mouth disease (HFMD) in Beijing and provide reference evidence in HFMD prevention and control.Methods:The monthly incidence data of HFMD in Beijing from 2008 to 2023 were collected from Notifiable Disease Management Information System of the Chinese Information System of Disease Control and Prevention, and the epidemiological characteristics of HFMD were analyzed by the methods of time series seasonal decomposition graph, concentration degree, and circular distribution.The WPS office software 2019 was used to clean the data, Python software 3.12 was used to analyze and make statistical charts.Results:The monthly incidence fluctuation of HFMD in Beijing from 2008 to 2015 was higher than that from 2016 to 2022. From 2016 to 2022, the fluctuation range of monthly incidence showed a gradually decreasing trend.From 2008 to 2015, the concentration ( M) was 0.58, indicating a relatively strong seasonality; the mean angle ( α) calculated by the circular distribution method was 174.95°, and the mean angle standard deviation ( s) was 60.43°. The annual incidence peak occurred on June 27, and the incidence peak period was from April 27 to August 27. From 2016 to 2019 and 2023, the M was 0.57, indicating a relatively strong seasonality. The α was 228.05°, and s was 61.44°. The annual incidence peak occurred on August 20, and the incidence peak period was from June 18 to October 21. From 2020 to 2022, the M was 0.42, indicating a seasonality, the α was 238.27° and s was 76.35°. The annual incidence peak occurred on July 15, and the incidence peak period was from June 14 to November 14. The α of 2008-2015, 2016-2019 and 2023, and 2020-2022 were tested by the Watson-Williams method and the difference was statistically significant ( F=33 443.09, P<0.001). In 2023, the M was 0.77, indicating a strong seasonality. The incidence peak occurred on September 16, and the incidence peak period was from August 5 to October 28. Conclusions:The seasonality of HFMD in Beijing was obvious from 2008 to 2023, and the incidence peak day and peak period overall had rearward shifts. It is necessary to strengthen the comprehensive analysis of the distribution characteristics at different dimensions and the comprehensive prevention and control in key areas, places, and populations during the peak incidence period.

Background Patients with schizophrenia of Yangming Fushi syndrome experience more severe symptoms,and a substantial proportion of patients derive inadequate benefit from antipsychotics and suffer from serious adverse effects,yet few studies have been conducted on the treatment of schizophrenia of Yangming Fushi syndrome with Zengye Chengqi decoction.Objective To explore the efficacy of Zengye Chengqi decoction combined with olanzapine in the treatment of schizophrenia of Yangming Fushi syndrome,in order to provide references for the treatment of schizophrenia with the combination of traditional Chinese and western medicine.Methods A total of 60 patients attending the Second Affiliated Hospital of Xinxiang Medical College from January 2022 to August 2023 and fulfilling the International Classification of Diseases(ICD-10)diagnostic criteria for schizophrenia were enrolled,and assigned into study group(n=30)and control group(n=30)using random number table methods.All patients were treated with olanzapine,and study group was given Zengye Chengqi decoction on this basis.Treatment for both groups lasted for 4 weeks.All participants were assessed using Positive and Negative Syndrome Scale(PANSS),Montreal Cognitive Assessment(MoCA)and Event-Related Potential P300 at baseline and end of treatment.The occurrence of adverse reactions was recorded at the end of treatment.Results Study group reported a higher treatment effective rate compared with control group(χ2=9.320,P=0.002).After treatment,study group detected a significant reduction in PANSS subscales and total scores(F=10.287,8.258,8.844,20.079,P<0.01),and a notable increase in scores of delayed recall and orientation domains from MoCA(F=4.463,22.255,P<0.05 or 0.01)when compared with control group,with statistical difference.For the P3 component of event-related potential,study group produced significantly larger amplitudes than control group(F=4.247,P<0.05).The incidence rate of abnormal liver function,constipation and increased body mass index(BMI)in study group was lower than those in control group(χ2=4.320,4.463,7.200,P<0.05 or 0.01).Conclusion Zengye Chengqi decoction combined with olanzapine are found to be effective in improving the psychotic symptoms and cognitive function and alleviating the adverse reactions of patients with schizophrenia of Yangming Fushi syndrome.

The pattern differentiation method is the most representative part of the inheritance of the experience of renowned practitioners of traditional Chinese medicine,reflecting their clinical thinking characteristics. Among them,Professor LYU Renhe proposed and developed the theory of abdominal masses in the long-term diagnosis and treatment of kidney diseases. Based on his clinical experience,he formed the method of differentiation of Shenluozhengjia (tangible or intangible abdominal masses of kidney collaterals). This differentiation method is characterized by its simple and easy clinical application. Tangible or intangible abdominal masses of kidney collaterals refer to chronic kidney disease,which is based on the basic cause of kidney deficiency. External or internal pathogenic factors cannot be eliminated,and prolonged illness invades the kidney collaterals,causing pathological products,such as qi stagnation,blood stasis,phlegm dampness,heat toxin,and turbid toxin to stagnate in the kidney collaterals,resulting in damage to the kidney body and loss of kidney function. The basic pathogenesis is a deficiency of kidney qi and the formation of tangible or intangible abdominal masses of the kidney collaterals. During pattern differentiation,the type is determined by the deficiency,which is fixed,and the pattern is determined by the excess,which is constantly changing with the condition and can be combined. Furthermore,he summarized the dietary principles as having more essence and less coarseness,more milk and less meat,a phased diet,and the selection of the symptomatic diet. To inherit and improve the theory and clinical practice of the pattern differentiation theory of tangible or intangible abdominal masses of kidney collaterals,this article reviews and summarizes the unique pattern differentiation method of the kidney collateral pattern from the aspects of definition,theoretical origin,etiology and pathogenesis,differentiation and treatment,and regulation,providing a basis for forming suitable diagnosis and treatment method for clinical promotion.

Objective:To investigate the efficacy and cognitive function of 3 new antiepileptic drugs Oxcarbazepine (OXC), Lamotrigine (LTG) and Levetiracetam (LEV) in children with self-limited epilepsy with centrotemporal spikes (SeLECTS).Methods:This was a prospective study.A total of 98 children with SeLECTS who were treated in the Second Affiliated Hospital of Xinxiang Medical University from January 2014 to June 2020 were divided into OXC group, LTG group and LEV group according to the applied therapeutic drugs.Video electroencephalograph (EEG), Wechsler Intelligence Scale for Children (WISC) and event-related potentials (ERPs) of the children were collected before treatment and 48 weeks of treatment.Clinical efficacy and impact on cognitive function among the 3 groups were compared.Results:(1)Efficacy: There was no significant difference in the effective rate of seizure reduction after treatment among the 3 groups( χ2=0.808, P=0.668). There was no significant difference in EEG remission rate among the 3 groups( χ2=0.763, P=0.683). (2)Cognitive function: ①Intragroup comparison of WISC findings showed that the full scale score (FIQ) and verbal intelligence quotient (VIQ) were significantly enhanced, and the scores of comprehension, vocabulary, arithmetic, decoding and spelling subtests were more significantly enhanced in OXC group after treatment (all P<0.05). In the LTG group, FIQ, VIQ and operational intelligence quotient (PIQ) were significantly enhanced after treatment (all P<0.05), and the subtest scores of comprehension, vocabulary, arithmetic, mapping and layout were significantly enhanced (all P<0.05). In LEV group, FIQ, VIQ and PIQ were significantly enhanced after treatment (all P<0.05), especially the increase in the VIQ, and the scores of vocabulary, understanding, similarity, arithmetic, decoding and puzzle subtests were significantly enhanced (all P<0.05). Pairwise comparison of WISC findings showed that there were no significant differences in the FIQ, VIQ, PIQ and subtest scores before treatment among the 3 groups (all P>0.05). After treatment, the arithmetic and decoding scores of OXC group were significantly higher than those of LTG group (all P<0.05), which were comparable between OXC group and LEV group (all P>0.05). The PIQ and the scores of mapping and layout in LTG group were significantly higher than those of the other 2 groups (all P<0.05). The LEV group had higher scores in vocabulary, comprehension and spelling than those of the other 2 groups (all P<0.05), which had higher decoding scores than those of the LTG group (all P<0.05). No significant differences were found in decoding scores between LEV and OXC group (all P>0.05). Higher VIQ and FIQ were detected in LEV group than those of the other 2 groups (all P<0.05). ②Intragroup comparison of ERPs showed that the latency of LEV group after treatment was significantly shorter than that before treatment ( P<0.05), and there was no significant difference between the other 2 groups before and after treatment (all P>0.05). Pairwise comparison of ERPs showed that before treatment, there were no significant differences in P300 amplitude and latency among the 3 groups (all P>0.05). After treatment, the latency of LEV group was significantly shorter than that of the other 2 groups ( P<0.05), and there was no significant difference in the amplitude between the 3 groups before and after treatment ( P>0.05). Conclusions:(1)In the treatment of SeLECTS in children, OXC, LTG and LEV have reliable and equivalent effects.(2)OXC, LTG and LEV have protective effects on cognitive function in children with SeLECTS.After treatment, LEV provides the strongest protective effect on FIQ, and the protective effect on VIQ is equivalent to OXC, but better than LTG.LTG is superior in protecting spatial perception and PIQ.

ObjectiveTo investigate the status and influencing factors of medication adherence in patients with severe mental disorders in Zhengzhou， so as to provide references for the formulation of prevention and treatment measures for severe mental disorders. MethodsFrom March to June 2021， a stratified multistage cluster sampling method was applied to select 342 patients from the National Information System for Severe Mental Disorders in Zhengzhou. The general demographic data of patients were collected via self-designed questionnaire， and the medication status was investigated， then the influential factors were summarized. The differences in influential factors of medication adherence were compared between the medication adherence group and the medication non-adherence group. Thereafter， Logistic regression analysis was applied to explore the factors influencing medication adherence. ResultsA total of 320 patients were included in the final analysis， altogether 76.56% of patients （n=245） complied with medication. The differences between patients in the medication adherence group and those in the medication non-adherence group were statistically significant in terms of residence， occupation， and outpatient chronic disease reimbursement （χ²=14.015， 7.502， 13.106， P<0.05 or 0.01）. In the questionnaire of influential factors on medication adherence， there were statistically significant differences in the scores of lack of insight， stigma and drug-related factors between the two groups （Z=7.588， 2.379， 2.893， P<0.05 or 0.01）. Outpatient chronic disease reimbursement was a protective factor for medication adherence （OR=2.727， 95% CI： 1.320~5.634， P<0.01）， while rural residence （OR=0.465， 95% CI： 0.221~0.977， P<0.05） and lack of insight （OR=0.398， 95% CI： 0.286~0.553， P<0.01） were risk factors for medication adherence. ConclusionPatients with severe mental disorders in Zhengzhou have a high rate of medication adherence， moreover， the outpatient chronic disease reimbursement， lack of insight and residence may be influencing factors for medication adherence in patients with severe mental disorders.

ObjectiveTo explore the effect of flipped classroom mode in the clinical probation teaching for undergraduate mental health students， so as to expand the new mode of clinical teaching in psychiatry department. MethodsA total of 85 undergraduate psychiatric students from Xinxiang Medical University in 2016 were selected.
