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.

The Coronavirus Disease 2019 (COVID-19) pandemic has had an adverse impact on the physical and mental health of the public worldwide. In addition to illness in patients with COVID-19, isolated people and the general population have experienced mental health problems due to social distancing policies, mandatory lockdown, and other psychosocial factors, and the prevalence of depression and anxiety significantly increased during the pandemic. The purpose of this review is to elucidate the epidemiology, contributing factors, and pathogenesis of depression and anxiety. during the pandemic. These findings indicate that physicians and psychiatrists should pay more attention to and identify those with a high risk for mental problems, such as females, younger people, unmarried people, and those with a low educational level. In addition, researchers should focus on identifying the neural and neuroimmune mechanisms involved in depression and anxiety, and assess the intestinal microbiome to identify effective biomarkers. We also provide an overview of various intervention methods, including pharmacological treatment, psychological therapy, and physiotherapy, to provide a reference for different populations to guide the development of optimized intervention methods.

Objective: To analyze the epidemiological characteristics of infectious diseases at schools in Beijing from 2010 to 2020, providing evidence for the prevention and control strategies in school infectious diseases. Methods: Information on public health emergencies was collected from Public Health Emergency Reporting System (the subsystem of Chinese Disease Prevention and Control Information System) reported from 2010 to 2020. Results: A total of 146 public health emergencies and 138 public health emergencies of infectious diseases in schools were reported in Beijing from 2010 to 2020, including 4 291 cases with the rate of 2.32% and affected or exposed 185 179 cases. There were significant difference in mean annual incidence rates( χ 2=782.46, P <0.01). There were 71 events of respiratory infectious diseases and 66 events of intestinal infectious diseases, accounting for 51.45% and 47.83%, respectively. The annual incidence peaks of public health emergencies of infectious diseases were during March-June and October-December. The events mainly occurred in kindergartens and primary schools among each stage of school periods with 51 and 46 incidences respectively, which accounted for 70.29% of the total number of public health emergencies in schools. The leading infectious diseases among all the reported events in kindergartens and primary schools were hand foot mouth disease and varicella. Varicella and other infectious diarrhoeal diseases were at the top lists of infectious disease outbreaks at the secondary and university stages. Conclusion Infectious diseases events were the major type of public health emergencies at schools in Beijing from 2010 to 2020. Respiratory infectious diseases and intestinal infectious diseases were the keys to the prevention and control of public health emergencies related to school. It is necessary to strengthen the surveillance for public health emergencies especially for symptom surveillance. The prevention and control measures should be taken according to the characteristics of different age groups. At the same time, the prevention and control of school infectious diseases and the drill of the plan during peak periods need to be particularly strengthened.

Objective:To evaluate the post-marketing safety and immunogenicity of a 23-valent pneumococcal polysaccharide vaccine (PPV23).Methods:From September 2020 to June 2021, a clinical trial of single-dose PPV23 was conducted in people ≥3 years old in Centers for Disease Control and Prevention of Guizhou, Hunan and Fujian provinces. Blood samples were collects from the subjects before and 30 d after vaccination. ELISA was used to quantitatively detect IgG antibodies against capsular polysaccharides of 23 Streptococcus pneumoniae serotypes in serum samples. The adverse events (AEs) were monitored within 7 d after vaccination. Results:A total of 409 subjects were enrolled and included in safety analysis. Except for one with antibody level inversion, the other 408 participants were included in immunogenicity analysis. The levels of antibodies against the 23 Streptococcus pneumoniae serotypes were all increased after vaccination by an average of 4.24 folds. The two-fold growth rates of the antibodies ranged from 51.72% to 96.81% with a total two-fold growth rate of 78.59%. The overall rate of AEs was 27.14% (111/409). Local AEs were mainly pain, induration, redness and swollen. No serious adverse events related to vaccination occurred. Conclusions:This study preliminarily demonstrated the good immunogenicity and safety of PPV23 vaccine.

Hypothermia can have adverse effects on various systems of trauma patients, and significantly increase the mortality. All of the current rewarming equipments are contact rewarming equipment, which have the shortcomings of single function and poor effect. The medical staff of the First People's Hospital of Chenzhou designed a multi-functional infrared heating medical rewarming equipment, and obtained the National Utility Model Patent of China (ZL 2018 2 1705172.9). By integrating the infrared heating lamp tube and the air heating device and controlling them independently, the equipment can not only treat the wound by infrared alone, but also keep the wound warm by using the air heating function at low room temperature. In addition, it can also warm the patients with hypothermia separately. The device's dual functions of promoting wound healing and rewarming by infrared therapy and wind-heating are accurate. It is easy to operate with good controllability, and contributes to individualized precision treatment, which is worthy of transformation and promotion.

Objective To study the predicting value of four different scoring systems such as the acute physiology and chronichealth evaluation Ⅱ (APACHE Ⅱ) score, sequential organ failure assessment (SOFA) score, quick SOFA (qSOFA) score and systemic inflammatory response syndrome (SIRS) score for the prognosis of septic patients. Methods A retrospective analysis were conducted. Septic patients in intensive care unit (ICU) of the First People's Hospital of Chenzhou form July 1st, 2012 to June 30th, 2016 were enrolled.Patients were divided into survival group and death group according to 28-day outcome. The difference of clinic data, the worst clinical index value within 24 hours, whether mechanical ventilation performed on first day, length of stay in ICU, APACHE Ⅱ score, SOFA score, qSOFA score and SIRS score were compared between the two groups. The significant different factors of sepsis outcome in univariate analysis were analyzed by multiple logistic regression, and the ability of four scoring systems was tested by receiver operating characteristic (ROC) curve.Results 311 patients were enrolled in this study (221 survivals, 90 deaths, 28-day mortality rate 28.9%). Univariate analysis showed age, mechanical ventilation ratio, urine output, length of stay in ICU and the fastest heart beat rate (HR), the lowest systolic blood pressure (SBP), the lowest mean arterial pressure (MAP), HCO3-, minimum arterial blood oxygen partial pressure (PaO2), minimum oxygenation index (PaO2/FiO2), the maximum fraction of inspired oxygen (FiO2), Na+, the highest concentration of blood urea nitrogen (BUN), the highest concentration of serum creatinine (SCr), minimum concentration of plasma albumin (Alb), Glasgow coma score (GCS) score, APACHE Ⅱ score, SOFA score, qSOFA score, within 24 hours after diagnosis were significantly different between two groups (allP < 0.05). Multiple logistic regression showed age [odds ratio (OR) = 1.388, 95% confidence interval (95%CI) = 1.074-1.794,P = 0.012], PaO2/FiO2 (OR = 0.459, 95%CI = 0.259-0.812,P = 0.007), concentration of plasma Alb (OR = 0.523, 95%CI = 0.303-0.903,P = 0.020), GCS score (OR = 0.541, 95%CI = 0.303-0.967,P = 0.038) and SOFA scores (OR = 3.189, 95%CI = 1.813-5.610,P = 0.000) were independent risk factors for sepsis outcome. ROC curve test showed the APACHE Ⅱ score, SOFA score and qSOFA score had the ability to predict the outcome in critical ill patients with sepsis, the SOFA score of the most powerful, the area under the ROC curve (AUC) was 0.700,when the cut-off value was 7.5 points, the sensitivity was 73.3% and specificity was 58.8%.Conclusions APACHE Ⅱ score, SOFA score and qSOFA score have the predictive properties for septic patients. SOFA score is an independent prognostic risk factor of sepsis, while qSOFA score can be widely used in clinical practice as the advantage of quick evaluating.
