Abstract
Objective: To investigate the role of RNA m6A methylation in mediating cerebellar dysplasia through analyzing the phenotypes of the mouse cerebella and the expression of several key m6A regulators upon hypobaric hypoxia treatment. Methods: Five-day old C57/BL6 mice were exposed to hypobaric hypoxia for 9 days. The status of mouse cerebellar development was analyzed by comparing the body weights, brain weights and histological features. Immunostaining of cell-type-specific markers was performed to analyze the cerebellar morphology. Real-time PCR, Western blot and immunohistochemical staining were performed to detect the expression of key m6A regulators in the mouse cerebella. Results: Compared with the control, the body weights, brain weights and cerebellar volumes of hypobaric hypoxic mice were significantly reduced (P<0.01). The expression of specific markers in different cells, including NeuN (mature neuron), Calbindin-D28K (Purkinje cell) and GFAP (astrocyte), was decreased in hypobaric hypoxic mouse cerebella (P<0.01), accompanied with disorganized cellular structure. The expression of methyltransferase METTL3 was significantly down-regulated in the cerebella of hypobaric hypoxic mice (P<0.05). Conclusions: Hypobaric hypoxia stimulation causes mouse cerebellar dysplasia, with structural abnormalities in mature granular neurons, Purkinje cells and astrocytes. Expression of METTL3 is decreased in hypobaric hypoxic mice cerebellum compared with that of normobaric normoxic mice, suggesting that its mediated RNA m6A methylation may play an important role in hypobaric hypoxia-induced mouse cerebellar dysplasia.

Abstract
Objective: To investigate the clinical characteristics of 130 children with severe SARS-CoV-2 infection in Yunnan province after the relaxation of non-pharmaceutical interventions, and analyze the risk factors for mortality. Methods: This study is a retrospective case summary that analyzed the demographic data, underlying diseases, clinical diagnoses, disease outcomes, and laboratory results of 130 children with severe COVID-19 infections admitted to nine top-tier hospitals in Yunnan Province from December 2022 to March 2023. According to the prognosis, the patients were divided into survival group and death group. The clinical and laboratory data between the two groups were compared, and the risk factors of death were evaluated. The χ2 test and Mann-Whitney U test were employed to compare between groups, while Spearman correlation test and multiple Logistic regression were used to analyze the risk factors for death. The predictive value of independent risk factors was evaluated by receiver operating characteristic curve. Results: The 130 severe patients included 80 males and 50 females with an onset age of 28.0 (4.5, 79.5) months. There were 97 cases in the survival group and 33 cases in the death group with no significant differences in gender and age between the two groups (P>0.05). Twenty-five cases (19.2%) out of the 130 patients had underlying diseases, and the number with underlying diseases was significantly higher in death group than in survival group (36.4% (12/33) vs. 13.4%(13/97), χ2=8.36, P=0.004). The vaccination rate in the survival group was significantly higher than that in the death group (86.1% (31/36) vs. 7/17, χ2=9.38, P=0.002). A total of 42 cases (32.3%) of the 130 patients were detected to be infected with other pathogens, but there was no significant difference in the incidence of co-infection between the death group and the survival group (39.3%(13/33) vs. 29.9% (29/97), χ2=1.02, P>0.05). Among the 130 cases, severe respiratory cases were the most common 66 cases (50.8%), followed by neurological severe illnesses 34 cases (26.2%) and circulatory severe 13 cases (10%). Compared to the survival group, patients in the death group had a significantly higher levels of neutrophil, ferritin, procalcitonin, alanine aminotransferase, lactate dehydrogenase, creatine kinase isoenzyme, B-type natriuretic peptide, interleukin-6 and 10 (6.7 (4.0, 14.0) vs. 3.0 (1.6, 7.0)×109/L, 479 (298, 594) vs. 268 (124, 424) μg/L, 4.8 (1.7, 10.6) vs. 2.0 (1.1, 3.1) μg/L, 66 (20, 258) vs. 23 (15, 49) U/L, 464 (311, 815) vs. 304 (252, 388) g/L, 71(52, 110) vs. 24(15, 48) U/L, 484 (160, 804) vs. 154 (26, 440) ng/L, 43 (23, 102) vs. 19 (13, 27) ng/L, 216 (114, 318) vs. 86 (45, 128) ng/L, Z=-4.21, -3.67, -3.76, -3.31, -3.75, -5.74, -3.55, -4.65, -5.86, all P<0.05). The correlated indexes were performed by multivariate Logistic regression and the results showed that vaccination was a protective factor from death in severe cases (OR=0.01, 95%CI 0-0.97, P=0.049) while pediatric sequential organ failure assessment (PSOFA) (OR=3.31, 95%CI 1.47-7.47, P=0.004), neutrophil-to-lymphocyte ratio (NLR) (OR=1.56, 95%CI 1.05-2.32, P=0.029) and D dimer (OR=1.49, 95%CI 1.00-1.02, P=0.033) were independent risk factors for death (all P<0.05). The area under the curve of the three independent risk factors for predicting death were 0.86 (95%CI 0.79-0.94), 0.89 (95%CI 0.84-0.95) and 0.87 (95%CI 0.80-0.94), all P<0.001, and the cut-off values were 4.50, 3.66 and 4.69 mg/L, respectively. Conclusions: Severe SARS-CoV-2 infection can occur in children of all ages, primarily affecting the respiratory system, but can also infect the nervous system, circulatory system or other systems. Children who died had more severe inflammation, tissue damage and coagulation disorders. The elevations of PSOFA, NLR and D dimer were independent risk factors for death in severe children.

Abstract
PURPOSE To synthesise qualitative research on the parental hope experiences for children with cancer and identify the levels of parental hope experiences and psychosocial adjustment during cancer events. METHODS Five electronic databases (Cochrane Library, PubMed, Embase, Web of Science, and CINAHL) and three Chinese databases (CNKI, Wanfang, and VIP) were used to retrieve qualitative studies on the hope experiences of parents of children with cancer from inception to February 2023. The Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI) was used to assess the methodological quality of the included studies. Data were synthesised using a thematic analysis. RESULTS Four analytical themes were identified: the process and way hope exists, sources of hope, positive effects of hope, and obstacles to hope maintenance. CONCLUSIONS Maintaining hope is crucial for parents who are caring for their children with cancer. There are different sources of hope, and targeted interventions can enhance the experience of hope for parents of children with cancer. Families, healthcare providers, and society should pay more attention to the parents of children with cancer and provide them with psychological, social, and financial support to improve their level of hope and quality of care.

Abstract
OBJECTIVE The aim of this study was to investigate the value of Broncoplasma Insufflation Sign in lung ultrasound signs in assessing the efficacy of bronchoalveolar lavage in Severe mycoplasma pneumoniae pneumonia in children. METHODS Forty-seven children with Severe mycoplasma pneumoniae pneumonia were treated with medication and bronchial lavage. Laboratory and imaging results were collected, and lung ultrasonography was performed before bronchoalveolar lavage and 1, 3, and 7 days after lavage to record changes in Bronchial Insufflation Sign and changes in the extent of solid lung lesions. Factors affecting the effectiveness of bronchoalveolar lavage were analyzed using logistic regression and other factors. RESULTS Bronchial Insufflation Sign Score and the extent of lung solid lesions were the factors affecting the effectiveness of bronchoalveolar lavage treatment. The smaller the area of lung solid lesions and the higher the Bronchial Insufflation Sign Score, the more effective the results of bronchoalveolar lavage treatment were, and the difference was statistically significant, with a difference of p < 0.05. The Bronchial Insufflation Sign Score had the highest sensitivity and specificity for the prediction of the efficacy of bronchoalveolar lavage treatment in the first 7 days after the treatment. CONCLUSION Bronchial Insufflation Sign Score combined with the extent of solid lung lesions can assess the efficacy of bronchoalveolar lavage in the treatment of Severe mycoplasma pneumoniae pneumonia in children; lung ultrasound is a timely and effective means of assessing the efficacy of bronchoalveolar lavage.

Abstract
Objective: To analyze the clinical features of children with cryptogenic organizing pneumonia (COP) confirmed by pathology. Methods: The clinical manifestations, imaging, pathology, treatment and outcome data of 4 children with COP confirmed by thoracoscopic lung biopsy were retrospectively analyzed, who were hospitalized at Respiratory Department of Shenzhen Children's Hospital from January 2004 to December 2022. Results: All of the 4 patients were male, the age ranged from 1 year 3 months to 14 years. The time from onset to diagnosis was 3 months to 3 years. The follow-up duration was 6 months to 6 years. All the 4 cases had cough, 2 cases had tachypnea and wheezing, 1 case had expectoration, 1 case had chest pain, 1 case had decreased activity tolerance and weight loss. Rales in 2 cases and hypoxemia in 1 case. Pulmonary high resolution CT showed diffuse distribution, involvement of both lungs in 3 cases, and single lung combined migration in 1 case.Three cases showed ground-glass opacity, consolidation, patchy or fibrous strips, and 1 case presented air bronchogram and "reversed halo sign". All the 4 cases were performed thoracoscopic lung biopsy, and the pathological findings showed cellulose exudate or small nodules filled with granulation tissue or fibroblasts in the alveolar cavity and small airways, and 1 case was Masson corpuscle positive. Three patients achieved remission after glucocorticoid therapy. Spontaneous remission without treatment was seen in 1 patient.Two cases were followed up for 17 months and 6 years, respectively, who had excellent outcome. Conclusions: The manifestations of COP in children include cough, expectoration and chest pain. Infants and young children may have tachypnea and wheezing. The most common chest CT findings are diffuse distribution of ground-glass opacity, patchy and consolidation in both lungs. Diagnosis should depend on pathological examination. The effect of glucocorticoid therapy is good.

Abstract
The identification of the electrogenerated reactive intermediates is essential for an in-depth understanding of the electroredox processes. Although various short-lived intermediates are well characterized by coupling electrochemistry with mass spectrometry (EC/MS), many electrogenerated transient species (τ < 1 μs) are still rarely captured by the currently available EC/MS approaches. Here, we present a low-delay coupling device, which was constructed by decorating a microelectrode into the front tip of a microsized ion emitter. For the first time, the in situ detection of a previously hidden intermediate, i.e., the transient nitrenium ion of carbazole (τ = 333 ns), was achieved. The electrochemical generation of indole nitrenium ion, whose half-life is estimated to be shorter compared to the carbazole nitrenium ion due to less resonance stabilization, was also confirmed by direct observation. This clog-free microelectrode/ion emitter is cheap and easy to fabricate and offers a general and powerful approach to monitoring the fast reactions of electrogenerated reactive intermediates. We believe that our integrated EC/MS approach holds substantial potential for broad applicability, particularly in probing the intricate and ultrafast electroredox processes occurring at the electrode-solution interface.

Abstract
Objective: To analyze the iodine nutrition status of children aged 8 to 10 years in Zhejiang Province from 2016 to 2021. Methods: A multi-stage stratified sampling method was used to select non-residential children aged 8 to 10 years from 90 counties in Zhejiang Province. A total of 114 103 children were included in the study from 2016 to 2021. Direct titration method and arsenic-cerium catalytic spectrophotometry were used to detect salt iodine content and urinary iodine level, respectively, to evaluate the iodine nutritional status of children. Ultrasound was used to detect thyroid volume and analyze the current prevalence of goiter in school-age children. Results: The age of 114 103 children was (9.04 ± 0.81) years old, with 50.0% of (57 083) boys. The median of iodine content M (Q1, Q3) in children's household salt was 23.00 (19.80, 25.20) mg/kg, including 17 242 non-iodized salt, 6 173 unqualified iodized salt, and 90 688 qualified iodized salt. The coverage rate of iodized salt was 84.89%, and the coverage rate of qualified iodized salt was 79.48%. The proportion of non-iodized salt increased from 11.85% in 2016 to 16.04% in 2021 (χ2trend=111.427, P<0.001). The median of urinary iodine concentration M (Q1, Q3) in children was 182.50 (121.00, 261.00) μg/L, among which the proportions of iodine deficiency, iodine suitability, iodine over suitability, and iodine excess were 17.25% (19 686 cases), 39.21% (44 745 cases), 26.85% (30 638 cases), and 16.68% (19 034 cases), respectively. The median of urinary iodine concentration in children in inland areas [M (Q1, Q3): 190.90 (128.80, 269.00) μg/L] was significantly higher than that in children in coastal areas [M (Q1, Q3): 173.00 (113.00, 250.30) μg/L] (P<0.001). From 2016 to 2021, a total of 39 134 ultrasound examinations were conducted, and 1 229 cases of thyroid enlargement were detected. The goiter rate was 3.14% (95%CI: 2.97%-3.32%). The incidence of goiter in children in coastal areas [3.45% (95%CI: 3.19%-3.72%), 641/18 604] was higher than that in children in inland areas [2.86% (95%CI: 2.64%-3.10%), 588/20 530] (P=0.001). Conclusion: From 2016 to 2021, the iodine nutrition level of children aged 8-10 years in Zhejiang Province is generally suitable, and the rate of goiter in children meets the limit of iodine deficiency disease elimination standards.

Abstract
On the basis of the mechanisms of action and characteristics of immune effects, immunity is commonly categorized into innate and adaptive immunity. Adaptive immunity is associated with the response to non-self-entities and is characterized by high specificity and memory properties. In contrast, innate immunity has traditionally been considered devoid of memory characteristics. However, an increasing number of studies have sought to challenge this conventional immunological dogma and shown that innate immune cells exhibit a more robust and rapid response to secondary stimulation, thus providing evidence of the immunological memory in innate immunity. Macrophages, which are among the most important innate immune cells, can also acquire memory phenotype that facilitates the mediation of recall responses. Macrophage memory is a relatively new concept that is revolutionizing our understanding of macrophage biology and immunological memory and could lead to a new class of vaccines and immunotherapies. In this review, we describe the characteristics and mechanisms of macrophage memory, as well as its essential roles in various diseases.

The present study aimed to investigate the current situation of internet gaming disorder (IGD) in Chinese adolescents and explore the impact of IGD-related factors on adolescent aggression. We hypothesized that IGD symptoms in adolescents would be associated with aggressive behavior and that risk factors for IGD symptoms could increase the aggressive tendencies of adolescents. To verify the above hypothesis, a cross-sectional survey of junior and senior high school students from southern, southwestern, central, and eastern China was conducted. A total of 9306 valid questionnaires were collected. The results showed that the prevalence of IGD symptoms was 1.78 % among Chinese adolescents. The adolescents in the disordered gamer group had the most severe IGD symptoms, with the highest levels of psychological distress and aggression. Interestingly, adolescents in the casual gamer group had the lowest psychological distress and aggression scores. Linear regression analysis further showed that higher levels of aggression were significantly associated with male sex, younger age, more severe psychological distress and IGD symptoms, and more violent game exposure. Our results suggested that excessive online gaming not only contributes to psychological distress in adolescents but also increases their levels of aggressive behavior. Apart from male sex and younger age, severe IGD symptoms and psychological distress are the most important predictors of the development of aggressive behavior.

Abstract
BACKGROUND Palliative care is fraught with numerous challenges when it comes to conducting practical teaching as it involves caring for people facing the complexities of end-of-life and death. Insufficient clinical practice hinders nursing students from mastering knowledge, attitude and ability of hospice care. Virtual clinical simulation has demonstrated its effectiveness as a valuable educational tool in nursing. However, there is a dearth of evidence supporting its utilization in the context of palliative care practice education. OBJECTIVE To develop a virtual clinical simulation education system and assess its impact on enhancing nursing students' knowledge, ability, and attitudes toward palliative care. DESIGN A single-group pretest-posttest design and focus group interviews were employed. SETTING The study was conducted at a medical university in southwest China. PARTICIPANTS A total of 76 third-year nursing students participated. METHODS Participants underwent a 1-hour learning session using the virtual clinical simulation education system. Pre-test and post-test evaluations were conducted to assess the participants' knowledge, ability, and attitudes toward palliative care. Survey questionnaire was administered to gauge the students' acceptance and perception of virtual clinical simulation. Focus group interviews were integrated to gain insight into students' subjective perceptions and feedback on the virtual clinical simulation. RESULTS There were notable enhancements in the students' overall scores of palliative care knowledge, ability, and attitudes after the learning session. Students positively evaluated the usefulness and usability of virtual clinical simulation. Students' feedback regarding virtual clinical simulation can be categorized into four themes: the value of virtual clinical simulation education system, its role as a complement to clinical practice teaching, the enjoyment and accessibility of learning, and the technological challenges encountered. CONCLUSION Virtual clinical simulation is an effective learning tool in palliative care practice education, which has the potential to enhance students' knowledge, ability, and attitudes toward palliative care.

Abstract
Müller cells are important glial cells in the retina, which play important roles in maintaining the stability of the retina by mechanical support, homeostasis, and physiological metabolism, as well as protecting photoreceptor cells and retinal pigment epithelial cells. The degeneration and destruction of Müller cells are often accompanied by various retinal diseases, and the function of Müller cells is changed under pathological conditions. Based on the summary of the morphology, distribution and function of Müller cells, this article analyzes the different manifestations and changes of Müller cells in different stages of macular hole and the closely related mechanisms, aiming to clarify the role of Müller cells in the formation and development of macular hole and to provide reference for the prediction of disease progression and guidance of treatment.(This article was published ahead of print on the official website of Chinese Journal of Ophthalmology on Augest 28, 2023).

Abstract
Objective: To evaluate the safety of double and a half layered esophagojejunal anastomosis in radical gastrectomy. Methods: This prospective, multi-center, single-arm study was initiated by the Affiliated Cancer Hospital of Zhengzhou University in June 2021 (CRAFT Study, NCT05282563). Participating institutions included Nanyang Central Hospital, Zhumadian Central Hospital, Luoyang Central Hospital, First Affiliated Hospital of Henan Polytechnic University, First Affiliated Hospital of Henan University, Luohe Central Hospital, the People's Hospital of Hebi, First People's Hospital of Shangqiu, Anyang Tumor Hospital, First People's Hospital of Pingdingshan, and Zhengzhou Central Hospital Affiliated to Zhengzhou University. Inclusion criteria were as follows: (1) gastric adenocarcinoma confirmed by preoperative gastroscopy;(2) preoperative imaging assessment indicated that R0 resection was feasible; (3) preoperative assessment showed no contraindications to surgery;(4) esophagojejunostomy planned during the procedure; (5) patients volunteered to participate in this study and gave their written informed consent; (6) ECOG score 0-1; and (7) ASA score I-III. Exclusion criteria were as follows: (1) history of upper abdominal surgery (except laparoscopic cholecystectomy);(2) history of gastric surgery (except endoscopic submucosal dissection and endoscopic mucosal resection); (3) pregnancy or lactation;(4) emergency surgery for gastric cancer-related complications (perforation, hemorrhage, obstruction); (5) other malignant tumors within 5 years or coexisting malignant tumors;(6) arterial embolism within 6 months, such as angina pectoris, myocardial infarction, and cerebrovascular accident; and (7) comorbidities or mental health abnormalities that could affect patients' participation in the study. Patients were eliminated from the study if: (1) radical gastrectomy could not be completed; (2) end-to-side esophagojejunal anastomosis was not performed during the procedure; or (3) esophagojejunal anastomosis reinforcement was not possible. Double and a half layered esophagojejunal anastomosis was performed as follows: (1) Open surgery: the full thickness of the anastomosis is continuously sutured, followed by embedding the seromuscular layer with barbed or 3-0 absorbable sutures. The anastomosis is sutured with an average of six to eight stitches. (2) Laparoscopic surgery: the anastomosis is strengthened by counterclockwise full-layer sutures. Once the anastomosis has been sutured to the right posterior aspect of the anastomosis, the jejunum stump is pulled to the right and the anastomosis turned over to continue to complete reinforcement of the posterior wall. The suture interval is approximately 5 mm. After completing the full-thickness suture, the anastomosis is embedded in the seromuscular layer. Relevant data of patients who had undergone radical gastrectomy in the above 12 centers from June 2021 were collected and analyzed. The primary outcome was safety (e.g., postoperative complications, and treatment). Other studied variables included details of surgery (e.g., surgery time, intraoperative bleeding), postoperative recovery (postoperative time to passing flatus and oral intake, length of hospital stay), and follow-up conditions (quality of life as assessed by Visick scores). Result: [1] From June 2021 to September 2022,457 patients were enrolled, including 355 men and 102 women of median age 60.8±10.1 years and BMI 23.7±3.2 kg/m2. The tumors were located in the upper stomach in 294 patients, mid stomach in 139; and lower stomach in 24. The surgical procedures comprised 48 proximal gastrectomies and 409 total gastrectomies. Neoadjuvant chemotherapy was administered to 85 patients. Other organs were resected in 85 patients. The maximum tumor diameter was 4.3±2.2 cm, number of excised lymph nodes 28.3±15.2, and number of positive lymph nodes five (range one to four. As to pathological stage,83 patients had Stage I disease, 128 Stage II, 237 Stage III, and nine Stage IV. [2] The studied surgery-related variables were as follows: The operation was successfully completed in all patients, 352 via a transabdominal approach, 25 via a transhiatus approach, and 80 via a transthoracoabdominal approach. The whole procedure was performed laparoscopically in 53 patients (11.6%), 189 (41.4%) underwent laparoscopic-assisted surgery, and 215 (47.0%) underwent open surgery. The median intraoperative blood loss was 200 (range, 10-1 350) mL, and the operating time 215.6±66.7 minutes. The anastomotic reinforcement time was 2 (7.3±3.9) minutes for laparoscopic-assisted surgery, 17.6±1.7 minutes for total laparoscopy, and 6.0±1.2 minutes for open surgery. [3] The studied postoperative variables were as follows: The median time to postoperative passage of flatus was 3.1±1.1 days and the postoperative gastrointestinal angiography time 6 (range, 4-13) days. The median time to postoperative oral intake was 7 (range, 2-14) days, and the postoperative hospitalization time 15.8±6.7 days. [4] The safety-related variables were as follows: In total, there were 184 (40.3%) postoperative complications. These comprised esophagojejunal anastomosis complications in 10 patients (2.2%), four (0.9%) being anastomotic leakage (including two cases of subclinical leakage and two of clinical leakage; all resolved with conservative treatment); and six patients (1.3%) with anastomotic stenosis (two who underwent endoscopic balloon dilation 21 and 46 days after surgery, the others improved after a change in diet). There was no anastomotic bleeding. Non-anastomotic complications occurred in 174 patients (38.1%). All patients attended for follow-up at least once, the median follow-up time being 10 (3-18) months. Visick grades were as follows: Class I, 89.1% (407/457); Class II, 7.9% (36/457); Class III, 2.6% (12/457); and Class IV 0.4% (2/457). Conclusion: Double and a half layered esophagojejunal anastomosis in radical gastrectomy is safe and feasible.

Abstract
Arbuscular mycorrhizal fungi (AMF) have the function of promoting water absorption for the host plant, whereas the role of easily extractable glomalin-related soil protein (GRSP), an N-linked glycoprotein secreted by AMF hyphae and spores, is unexplored for citrus plants. In this study, the effects on plant growth performance, root system characteristics, and leaf water status, along with the changes of mineral element content and relative expressions of tonoplast intrinsic protein (TIP) genes in lemon (Citrus limon L.) seedlings, were investigated under varying strengths of exogenous EE-GRSP application under potted conditions. The results showed that 1/2, 3/4, and full-strength exogenous EE-GRSP significantly promoted plant growth performance, as well as increased the biomass and root system architecture traits including root surface area, volume, taproot length, and lateral root numbers of lemon seedlings. The four different strengths of exogenous GRSP displayed differential effects on mineral element content: notably increased the content of phosphorus (P) and iron (Fe) in both leaves and roots, as well as magnesium (Mg) and zinc (Zn) content in the roots, but dramatically decreased the content of calcium (Ca) and manganese (Mn) in the roots, as well as Zn and Mn in the leaves. Exogenous EE-GRSP improved leaf water status, manifesting as decreases in leaf water potential, which was associated with the upregulated expressions of tonoplast intrinsic proteins (TIPs), including ClTIP1;1, ClTIP1;2, ClTIP1;3, ClTIP2;1, ClTIP2;2, ClTIP4;1, and ClTIP5;1 both in leaves and roots, and TIPs expressions exhibited diverse responses to EE-GRSP application. It was concluded that exogenous EE-GRSP exhibited differential responses on plant growth performance, which was related to its strength, and the effects were associated with nutrient concentration and root morphology, especially in the improvement in water status related to TIPs expressions. Therefore, EE-GRSP can be used as a biological promoter in plant cultivation, especially in citrus.

Abstract
Objective: To understand the prevalence of insufficient physical activity among adults aged ≥18 years in China and to explore the influencing factors. Methods: The China Chronic Disease and Risk Factor Surveillance was conducted in 298 counties/districts in China in 2018, covering 31 provinces (autonomous regions, municipalities). A multi-stage stratified cluster random sampling method was used to select permanent residents aged ≥18 years. A questionnaire including Global Physical Activity Questionnaire was used to collect information about the participants' demographic characteristics and physical activity through face-to-face interview. A total of 183 769 participants completed the survey. After complex data weighting, the prevalence of insufficient physical activity, occupation, transportation, and leisure-time physical activity time was analyzed. Multivariate logistic regression models were used to analyze the influencing factors related to insufficient physical activity. Results: The prevalence of insufficient physical activity among adults aged ≥18 years was 22.3% (95%CI: 20.9%-23.7%) in China in 2018, with males [24.4% (95%CI: 23.0%-25.8%)] significantly higher than females [20.2% (95%CI: 18.6%-21.8%)]. Adults aged 70 years and above [28.4% (95%CI: 26.9%-29.9%)] were significantly higher than adults in other age groups, followed by adults aged 18-29 years [26.4% (95%CI: 24.4%- 28.3%)] and 30-39 years [23.4% (95%CI: 21.5%-25.3%)], and tended to increase with increasing education and total sedentary behavior time (P<0.001). The weekly occupation, transportation, and leisure-time physical activity time appeared 958.6 (95%CI: 911.4-1 005.8) minutes, 234.5 (95%CI: 224.7- 244.2) minutes, and 88.6 (95%CI: 83.5-93.7) minutes, respectively. Multivariate logistic regression analysis showed that males, adults living in rural areas or northern China, ≥70 years, with junior high school education, an annual household income per capita <6 000 yuan and institutional/clerical/ technical occupation and longer total sedentary behavior time were related to a higher prevalence of insufficient physical activity. Conclusions: In China, over one-fifth of the adults had lower physical activity levels. Adults who are male, young adults, more educated, institutional/clerical/technical occupation, and with more extended total sedentary behavior are the populations that need to be focused on to promote physical activity-related health.

Abstract
Objective: To assess the cardiovascular health status of adults in China by using the "Life's Essential 8" score, and provide reference for the development and improvement of cardiovascular disease prevention and control policies and measures. Methods: Chronic Disease and Nutrition Surveillance was conducted in 298 counties/districts in 2015 in 31 provinces (autonomous regions, municipalities) across China, multi-stage stratified cluster random sampling was used to select 45 households in each village or neighborhood, and 20 households were further selected to conduct dietary surveys. In this study, a total of 70 093 adults aged ≥20 years who completed the dietary survey and had complete information were included, their cardiovascular health status were assessed by using the "Life's Essential 8" score, a cardiovascular health scoring standard released by the American Heart Association in 2022. All results were adjusted using complex design-based sampling weights to achieve a better estimate of the population. Results: In 2015, the overall cardiovascular health score of Chinese adults aged ≥20 years was 73.3±12.6, the score was significantly higher in women (77.9±11.6) than in men (68.7±11.8), and higher in urban area (74.5±12.8) than in rural area (71.9±12.2), the differences were significant (P<0.001). It was estimated that about 0.25% (95%CI: 0.16%-0.33%) of adults in China had cardiovascular health score of 100, and 33.0% (95%CI: 31.6%-34.3%), 63.2% (95%CI: 62.1%-64.3%), and 3.9% (95%CI: 3.5%-4.2%) of adults had high, moderate and low cardiovascular health scores, respectively. The proportion of those with high cardiovascular health scores was relatively low in men, those with low education level, those with low income, those living in rural areas, and those living in southwest China (P<0.001). Of the eight factors, diet had the lowest mean score (46.0, 95%CI: 44.7-47.3), followed by blood pressure (59.4, 95%CI: 58.2-60.6) and tobacco exposure (61.4, 95%CI: 60.6-62.2). Conclusions: The cardiovascular health status of two-thirds of adult population in China needs to be improved. Diet, tobacco exposure, and blood pressure are the factors affecting the cardiovascular health of Chinese population, to which close attention needs to be paid, and men, rural residents, and those with lower socioeconomic status are key groups in cardiovascular health promotion.

Abstract
Objective: A Mendelian randomization (MR) analysis was performed to assess the relationship between tea consumption and cancer. Methods: There were 100 639 participants with the information of gene sequencing of whole genome in the China Kadoorie Biobank. After excluding those with cancer at baseline survey, a total of 100 218 participants were included in this study. The baseline information about tea consumption were analyzed, including daily tea consumption or not, cups of daily tea consumption, and grams of daily tea consumption. We used the two-stage least square method to evaluate the associations between three tea consumption variables and incidence of cancer and some subtypes, including stomach cancer, liver and intrahepatic bile ducts cancer, colorectal cancer, tracheobronchial and lung cancer, and female breast cancer. Multivariable MR and analysis only among nondrinkers were used to control the impact of alcohol consumption. Sensitivity analyses were also performed, including inverse variance weighting, weighted median, and MR-Egger. Results: We used 54, 42, and 28 SNPs to construct non-weighted genetic risk scores as instrumental variables for daily tea consumption or not, cups of daily tea consumption, and grams of daily tea consumption, respectively. During an average of (11.4±3.0) years of follow-up, 6 886 cases of cancer were recorded. After adjusting for age, age2, sex, region, array type, and the first 12 genetic principal components, there were no significant associations of three tea consumption variables with the incidence of cancer and cancer subtypes. Compared with non-daily tea drinkers, the HR (95%CI) of daily tea drinkers for cancer and some subtypes, including stomach cancer, liver and intrahepatic bile ducts cancer, colorectal cancer, tracheobronchial and lung cancer, and female breast cancer, are respectively 0.99 (0.78-1.26), 1.17 (0.58-2.36), 0.86 (0.40-1.84), 0.85 (0.42-1.73), 1.39 (0.85-2.26) and 0.63 (0.28-1.38). After controlling the impact of alcohol consumption and performing multiple sensitivity analyses, the results were similar. Conclusion: There is no causal relationship between tea consumption and risk of cancer in population in China.

Abstract
Cellulose-based dielectrics with attractive dielectric performance are promising candidates to develop eco-friendly electrostatic energy storage devices. Herein, all-cellulose composite films with superior dielectric constant were fabricated by manipulating the dissolution temperature of native cellulose, where we revealed the relationship among the hierarchical microstructure of the crystalline structure, the hydrogen bonding network, the relaxation behavior at a molecular level, and the dielectric performance of the cellulose film. The coexistence of cellulose I and cellulose II led to a weakened hydrogen bonding network and unstable C6 conformations. The increased mobility of cellulose chains in the cellulose I-amorphous interphase enhanced the dielectric relaxation strength of side groups and localized main chains. As a result, the as-prepared all-cellulose composite films exhibited a fascinating dielectric constant of as high as 13.9 at 1000 Hz. This work proposed here provides a significant step toward fundamentally understanding the dielectric relaxation of cellulose, thus developing high-performance and eco-friendly cellulose-based film capacitors.

Abstract
OBJECTIVE To explore the association between periconceptional supplementation of folic acid or multiple-micronutrients containing folic acid(MMFA) and risk of preterm delivery in women with natural conception, singleton pregnancy and vaginal delivery. METHODS A retrospective cohort study was performed based on the prenatal health care system and hospital information system of Tongzhou Maternal and Child Health Hospital of Beijing and the women who had their prenatal care in the hospital from January 2015 to December 2018 were included. The information of 16 332 women who conceived naturally, had a singleton pregnancy, and delivered vaginally was collected. Compliance scores were constructed based on the time of initiation and the frequency of taking nutritional supplements. The association between maternal periconceptional micronutrient supplementation, including pure folic acid (FA) pills or MMFA and the rate of preterm delivery was evaluated using Logistic regression models. RESULTS The preterm delivery rate (gestational week < 37 weeks) of the study population was 3.8%, and the mean (standard deviation) of gestational age was (38.98±1.37) weeks. A total of 6 174 (37.8%) women took FA during the periconceptional period, 8 646 (52.9%) women took MMFA, and 1 512 (9.3%) women did not take any nutritional supplements. The association between periconceptional supplementation of FA or MMFA and risk of preterm delivery in women was not statistically significant [adjusted odds ratio (aOR)=1.01, 95%CI: 0.74-1.37]. The associations with preterm birth were not statistically significant in further analysis by the type of nutritional supplements, time of initiation, and the frequency of supplementation. In addition, the association between the compliance score of taking supplements and the rate of preterm delivery was not statistically significant, either. CONCLUSION This study did not find an association between the risk of preterm delivery and the use of FA or MMFA during the periconcep-tional period in women with natural conception, singleton pregnancy, and vaginal delivery. In the future, multicenter studies with large-scale prospective cohort or population-based randomized controlled trials are warranted to confirm the association between taking FA or MMFA during the periconceptional period and preterm delivery among women.

Abstract
Groundwater is one of the major sources of water supply, especially in the western arid regions. However, with the deepening of the western development strategy, industrialization and urbanization have increased groundwater resource demands in Xining City. Overexploitation and utilization have led to a series of changes in the groundwater environment. Identifying the chemical evolution characteristics and formation mechanism of groundwater is crucial for preventing its deterioration and ensuring sustainable use. By combining hydrochemistry and multivariate statistical techniques, the chemical characteristics of groundwater in Xining City were analyzed, and the formation mechanism of groundwater and the influence of different factors were discussed. The results showed that there were as many as 36 chemical types of shallow groundwater in Xining City, mainly HCO3-Ca(Mg) (60.00%) and HCO3·SO4-Ca(Mg) (11.81%). There were 5-6 types of groundwater chemical types in bare land, grassland, and woodland. Groundwater chemical types in construction land and cultivated land were more complex, up to 21 types, indicating that they were strongly affected by human activities. The chemical evolution process of groundwater in the study area was mainly affected by rock weathering and leaching, evaporative crystallization, and cation exchange. The main controlling factors were water-rock interaction (contribution rate 27.56%) and industrial wastewater discharge (contribution rate 16.16%), acid-base environment (contribution rate 16.00%), excessive application of chemical fertilizers and pesticides (contribution rate 13.11%), and domestic sewage (contribution rate 8.82%). On account of the chemical characteristics of groundwater in Xining City and the influence of human activities, the management and control suggestions on the development and utilization of groundwater resources were put forward.

Abstract
Objective This study examined the prevalence of posttraumatic stress disorder (PTSD) symptoms in college students 1 month after the lockdown of Wuhan to identify possible risk factors for PTSD symptoms in a cross-sectional study. Methods Out of 10,502 who responded, 9,274 students impacted by the COVID-19 pandemic were included in our study. PTSD symptoms was evaluated by the Impact of Event Scale-revised (IES-R). Anxiety/depression symptoms were evaluated by the Kessler Psychological Distress Scale (K10). Personality traits, coping style, and social support were assessed by the Eysenck Personality Questionnaire-Revised Short Scale for Chinese (EPQ-RSC), the Simplified Coping Style Questionnaire (SCSQ), and the Social Support Rating Scale (SSRS). Logistic regression analysis was utilized to further explore risk factors for PTSD symptoms. Results More than 1 month after the COVID-19 outbreak, 13.1% of college students developed PTSD symptoms, indicating that COVID-19 associated stressful experiences were connected with PTSD symptoms. After the COVID-19 outbreak, subjects with symptomatologic PTSD symptoms were more likely to experience strained relationships with their family, to have close contact with COVID-19 patients and to drop out of college. The logistic regression model demonstrated the association factors of PTSD symptoms. Neuroticism, psychoticism and an avoidant coping style were associated with increased risk for PTSD symptoms, while an active coping style was protective against PTSD symptoms during this pandemic. Conclusion The results showed that PTSD symptoms was prevalent in Chinese college students 1 month after the COVID-19 outbreak. Effective psychological support work should be carried out accordingly.

Abstract
PURPOSE To conduct a meta-synthesis of qualitative studies on the post-traumatic growth experiences of childhood cancer survivors. METHOD Various databases, including PubMed, Cochrane Library, Web of Science, EMBASE, PsycInfo, ProQuest, Scopus, China National Knowledge Infrastructure (CNKI), Wanfang Data, China Science and Technology Journal Database (CSTJ), and China Biology Medicine (CBM) were used to retrieve qualitative studies on childhood cancer survivors who experienced post-traumatic growth. RESULTS Eight papers were included in this study, and similar fragments were combined to form eight categories, which were further combined into four synthesized findings: adjustment of cognitive system, enhancement of personal strength, improving relationships with others, resetting of life goals. CONCLUSIONS Post-traumatic growth was observed in some childhood cancer survivors. The potential resources and positive forces contributing to this growth are of great significance in the fight against cancer, in tapping into individual and social resources to help survivors grow, and in improving their survival rates and quality of life. It also provides a new perspective for healthcare providers regarding the relevant psychological interventions.

Abstract
Objective: To explore the effects of porcine urinary bladder matrix (UBM) on the motility and polarization of bone marrow-derived macrophages in mice, so as to provide evidence for the rational selection of stent in clinical wound repair. Methods: The method of experimental research was used. The microstructure of porcine UBM and absorbable dressing was observed under scanning electron microscope. Polyacrylamide gel electrophoresis was used to observe the protein distribution of the two stent extracts. The primary macrophages were induced from bone marrow-derived cells isolated from six 6-8-week-old male C57BL/6J mice (mouse age, sex, and strain, the same below) and identified. Three batches of macrophages were divided into porcine UBM extract group and absorbable dressing extract group. The cells in each group were cultured with Dulbecco's modified Eagle medium/F12 medium containing the corresponding extracts. The cell migration rate was detected and calculated on 1, 3, and 7 d after scratching by scratch test. The number of migrated cells at 12 and 24 h of culture was detected by Transwell experiment. The percentages of CD206 and CD86 positive cells at 24 h of culture was detected by flow cytometer. The numbers of sample in the above cell experiments were all 3. An incision was prepared on the left and right back of twelve mice, respectively. The left incision of each mouse was included in porcine UBM group and the right incision was included in absorbable dressing group, and the corresponding stents were implanted into the incisions respectively. On post operation day (POD) 7 and 14, the number of inflammatory cells infiltrated in the stent was detected by hematoxylin-eosin staining; the number of F4/80, transforming growth factor-β1 (TGF-β1), vascular endothelial growth factor (VEGF), and matrix metalloprotein-9 (MMP-9) positive cells and type Ⅰ collagen deposition in stents were observed by immunohistochemistry; the percentages of F4/80, CD86, and CD206 positive cells were observed by immunofluorescence staining. The numbers of sample in the above animal experiments were all 6. Data were statistically analyzed with analysis of variance for factorial design, analysis of variance for repeated measurement, and independent sample t test. Results: Porcine UBM has a dense basement membrane structure on one side and porous propria containing a fibrous structures on the other. Both sides of the absorbable dressing had three-dimensional porous structure. In the molecular weight range of (50-70)×103, multiple non-type Ⅰ collagen bands appeared in the lanes of porcine UBM extract, while no obvious bands appeared in the lanes of absorbable dressing extract. It had been identified that mouse bone marrow-derived cells had been successfully induced into macrophages. The cell migration rates in porcine UBM extract group were significantly higher than those in absorbable dressing extract group on 1, 3, and 7 d after scratching (with t values of 15.31, 19.76, and 20.58, respectively, P<0.05). The numbers of migrated cells in porcine UBM extract group were significantly more than those in absorbable dressing extract group at 12 and 24 h of culture (with t values of 12.20 and 33.26, respectively, P<0.05). At 24 h of culture, the percentage of CD86 positive cells in porcine UBM extract group ((1.27±0.19)%) was significantly lower than (7.34±0.14)% in absorbable dressing extract group (t=17.03, P<0.05);the percentage of CD206 positive cells in porcine UBM extract group was (73.4±0.7)%, significantly higher than (32.2±0.5)% in absorbable dressing extract group (t=119.10, P<0.05). On POD 7 and 14, the numbers of inflammatory cells infiltrated in the stents in porcine UBM group was significantly more than those in absorbable dressing group (with t values of 6.58 and 10.70, respectively, P<0.05). On POD 7 and 14, the numbers of F4/80, TGF-β1, VEGF, and MMP-9 positive cells in the stents in porcine UBM group were significantly more than those in absorbable dressing group (with t values of 46.11, 40.69, 13.90, 14.15, 19.79, 32.93, 12.16, and 13.21, respectively, P<0.05); type Ⅰ collagen deposition in the stents in porcine UBM group was more pronounced than that in absorbable dressing group; the percentages of CD206 positive cells in the stents in porcine UBM group were significantly higher than those in absorbable dressing group (with t values of 5.05 and 4.13, respectively, P<0.05), while the percentages of CD86 positive cells were significantly lower than those in absorbable dressing group (with t values of 20.90 and 19.64, respectively, P<0.05), and more M2-type macrophages were seen in the stents in porcine UBM group and more M1-type macrophages were seen in the stents in absorbable dressing group. Conclusions: Porcine UBM can enhance macrophage motility, induce M2 polarization and paracrine function, create a microenvironment containing growth factors such as TGF-β1 and MMP-9 tissue remodeling molecules, and promote tissue regeneration and extracellular matrix remodeling in mice.

Abstract
Introduction Fear memory generalization is regarded as the core characteristic of posttraumatic stress disorder (PTSD) development. However, the mechanism that contributes to the generalization of conditioned fear memory is still unclear. The generalization is generally considered to be a mismatch that occurs during memory consolidation. Methods Foot shocks and tones were given as unconditioned stress and conditioned stress, respectively for fear conditioning training. Immunofluorescence staining, western blotting and qPCR were performed to determine the expression of different genes in amygdala of mice after fear conditioning training. Cycloheximide was used as a protein synthesis inhibitor and 2-methyl-6-phenylethynyl-pyridine was injected for mGluR5 inhibition. Results Fear conditioning using caused incremental generalization, which was clearly observed during training. The density of c-Fos+ cells or the synaptic p-NMDAR expression did not differ with stress intensities. Strong-shock fear conditioning could induce significant mGluR5 de novo synthesis in the amygdala, which was not observed in the weak-shock group. Inhibition of mGluR5 impaired fear memory generalization induced by strong-shock fear conditioning, but the generalization level induced by weak-shock training was enhanced. Discussion These results indicated that mGluR5 in the amygdala is critical to the function of inappropriate fear memory generalization and suggested that this may be a potential target for the treatment of PTSD.

Abstract
Background and Objective Cerebrovascular diseases (CVDs), particularly cerebral stroke, remain a primary cause of disability and death worldwide. Accurate diagnosis of CVDs is essential to guide therapeutic decisions and foresee the prognosis. Different CVDs have different pathological processes while they have many signs in common with some other brain diseases. Thus, differential diagnoses of strokes from other primary and secondary CVDs are especially important and challenging. Methods This review is composed mainly based on searching PubMed articles between September, 2013 and December 26, 2022 in English. Key Content and Findings Neuroimaging is a powerful tool for CVD diagnosis including cerebral angiography, ultrasound, computed tomography, and positron emission tomography as well as magnetic resonance imaging (MRI). MRI excels other imaging techniques by its features of non-invasive, diverse sequences and high spatiotemporal resolution. It can detect hemodynamic, structural alterations of intracranial arteries and metabolic status of their associated brain regions. In acute stroke, differential diagnosis of ischemic from hemorrhagic stroke and other intracranial vasculopathies is a common application of MRI. By providing information about the pathological characteristics of cerebral diseases exhibiting different degrees of behavioral alterations, cognitive impairment, motor dysfunction and other indications, MRI can differentiate strokes from other primary CVDs involving cerebral small vessels and identify vascular dementia from hyponatremia, brain tumors and other secondary or non-primary CVDs. Conclusions Recent advances in MRI technology allow clinical neuroimaging to provide unique reference for differentiating many previously inconclusive CVDs. MRI technology is worthy of full exploration while breaking its limitations in clinical applications should be considered.

Abstract
Hemophagocytic syndrome (HPS), which is currently named as hemophagocytic lymphohistiocytosis (HLH), is a hyperinflammatory syndrome characterized by persistent fever, hepatosplenomegaly, pancytopenia and hemophagocytosis found in bone marrow, liver, spleen and lymph nodes due to excessive activation of macrophages and cytotoxic T cells. Macrophage activation syndrome (MAS) is a specific form of HLH induced by autoinflammatory/autoimmune disorders which can be life-threatening and requires multiple disciplines. In order to improve clinicians' understanding of MAS and standardize the clinical diagnosis and treatment practice of MAS, the rheumatology branch of Chinese Rheumatology Association organized domestic experts to formulate the diagnosis and treatment standard, in order to improve the diagnosis and treatment level of MAS and improve the prognosis of patients.

Abstract
Photorespiration has emerged as a hotspot in the evolution of photosynthesis owing to the energy loss during the process. To ensure the physiological functions of photorespiration such as light protection, H2O2 signaling, and stress resistance, separate the photorespiration glycolic acid flow, and minimize photorespiration loss, a balance must be maintained during the construction of photorespiratory metabolic branch. In this study, glycolate oxidase (GLO) and catalase (CAT) were introduced into potato (Solanum tuberosum) chloroplasts through the expression of fusion protein. Through the examination of phenotypic characteristics, photosynthesis, anatomical structure, and enzyme activity, the efficiency of the photorespiration pathway was demonstrated. The results showed that certain transgenic lines plants had shorter plant height and deformed leaves and tubers in addition to the favorable photosynthetic phenotypes of thicker leaves and larger and denser mesophyll cells. By Diaminobenzidine (DAB) staining analysis of the leaves, the intermediate H2O2 could not be decomposed in time to cause biomass decline and malformation, and the excessive glycolate shunt formed by the overexpression of the fusion protein affected other important physiological activities. Hence, the appropriate and coordinated expression of glycolate oxidase and catalase is essential for the establishment of photorespiration pathways in chloroplasts.

Abstract
Abstract
Background
Left ventricular remodeling (LVR) in patients with ST-segment elevation myocardial infarction (STEMI) may lead to poor prognosis in which circulating exosome miRNAs play a critical role. The aim of the present study is to identify specific exosome miRNAs for LVR in patients with STEMI.
Method
Plasma exosome miRNAs were assessed in 20 patients (90% male, mean age of 66.95±1.65 years) 3–6 months after STEMI and 24 healthy individuals (83% male, mean age of 33.2±0.93 years) by using qPCR. Of the 20 patients, 8 had post-STEMI LVR according to echocardiographic evaluation, and the others did not. Clinical biochemical data including total cholesterol, HDL-C, LDL-C, LDH and NT-pro-BNP were collected from the patients with STEMI at same time as exosome miRNAs assessment. Specific exosome miRNAs for LVR were identified by using qPCR. Correlations between the dysregulated exosome miRNAs and the clinical biochemical parameters in patients with STEMI were analyzed using spearman correlation test.
Results
Five exosome miRNAs including hsa-miR-181a-3p (p<0.05, fold change = 0.59), let-7d-3p (p=0.01, fold change = 0.51), hsa-miR-224-5p (p<0.01, fold change = 0.11), hsa-miR-23a-3p (p<0.01, fold change = 1.42) and miR-874-3p (p<0.01, fold change = 0.48) were dysregulated in the post-STEMI patients comparing with the healthy individuals. Among them, the exosome miR-181a-3p (p=0.01, fold change = 0.09) and let-7d-3p (p=0.01, fold change = 0.16) were significantly lower expressed in patients with LVR compared to those without (Figure 1). There was no significant difference in expression of the other three miRNAs between patients with and without LVR. Exosome hsa-miR-874-3p positively associated with LDH (p<0.01, r=0.50) in all the patients with STEMI. In vitro cell culture confirmed that the miR-874-3p mimics upregulated expression of apoptosis related gene BMF (p<0.05, fold change = 1.7) in cardiomyocyte. Exosome hsa-miR-23a-3p and hsa-miR-224-5p positively correlated with both HDL-C (p<0.01, r=0.61; p=0.02, r=0.50) and LDL-C (p=0.02, r=0.50; p<0.05, r=0.52) in all patients with STEMI. No correlation between the dysregulated exosome miRNAs and cholesterol or NT-ProBNP was observed (Figure 2).
Conclusions
Circulating exosome miR-181a-3p and let-7d-3p might play a potential role in LVR in patients 3–6 months after STEMI. Exosome hsa-miR-874-3p might be associated with cardiomyocyte injury. Hsa-miR-23a-3p and hsa-miR-224-5p demonstrated an activity in regulation of lipid metabolism and biosynthesis in patients with STEMI.

Abstract
OBJECTIVE To explore the relationship of the exposure to phthalate esters (PAE) and polycyclic aromatic hydrocarbons (PAH) with clinical premature delivery during early pregnancy. METHODS We conducted a baseline questionnaire survey among 821 pregnant women undergoing prenatal examination in Hubei Provincial Maternal and Child Health Care Hospital, collected their morning urine samples and followed them up to the outcomes of pregnancy. We quantitatively analyzed 10 PAE and 10 PAH metabolites in the urine samples, followed by Mann-Whitney U test, chi-square test, and logistic regression analysis. RESULTS The detection rate of the 5 factors exposed to was >80% while that of phthalic acid monobenzyl ester (MBzP) was <50% in PAEs; that of the 5 factors exposed to was >80%, that of 3-hydroxyphene (3-OHPHE) was 86.91% while that of 4-hydroxyphene (4-OHPHE) was <50% in PAHs. Logistic regression analysis showed that the risk of premature delivery was higher in the high MBzP- than in the low MBzP-exposure group (aOR = 2.26, 95% CI: 1.17-4.39). CONCLUSION High MBzP-exposure may be a risk factor for premature delivery.

Abstract
OBJECTIVE To explore the association of the 25-hydroxy vitamin D (25(OH)D) level in the serum with the early pregnancy outcome of frozen-thawed embryo transfer (FET). METHODS We selected 119 infertile women that underwent FET and detection of serum 25(OH)D in the Department of Reproductive Medicine of the General Hospital of Central Theater Command from April 2020 to December 2021. According the level of serum 25(OH)D, we divided the patients into three groups: 25(OH)D <45.0 nmol/L (n = 59), 25(OH)D 45.0-75.0 nmol/L (n= 47), and 25(OH)D ≥75.0 nmol/L but <375.0 nmol/L) (n = 13), compared the basic information and the rates of clinical pregnancy, embryo implantation and adverse pregnancy among the three groups, and investigated the factors affecting the early pregnancy outcome using binary logistic regression analysis. RESULTS No statistically significant differences were observed among the three groups in the age (≤42 yr), body mass index (BMI), endometrial thickness at the transplantation day (≥7 mm), numbers of embryos transferred and high-quality embryos transferred, or rates of clinical pregnancy, embryo implantation and adverse pregnancy (P > 0.05). Binary logistic regression analysis showed that the rate of early clinical pregnancy was significantly correlated with the level of serum 25(OH)D (OR: 1 064, P = 0.040) and the number of high-quality embryos transferred (OR: 0.495, P = 0.004), but not with the age (≤42 yr), BMI, endometrial thickness at the transplantation day (≥ 7 mm), number of embryos transferred, or the levels of E2 and progesterone at the transplantation day (P > 0.05). CONCLUSION The level of serum 25(OH)D is positively correlated with the early pregnancy outcome of FET. A high serum 25 (OH) D level can improve the outcome and can be used as a good indicator to predict the success rate of FET.

Abstract
BACKGROUND Autoimmune liver disease (AILD) has been considered a relatively uncommon disease in China, epidemiological data for AILD in patients with cirrhosis and acute decompensation (AD) is sparse.
AIM To investigate the prevalence, outcome and risk factors for AILD in cirrhotic patients complicated with AD in China.
METHODS We collected data from patients with cirrhosis and AD from two prospective, multicenter cohorts in hepatitis B virus endemic areas. Patients were regularly followed up at the end of 28-d, 90-d and 365-d, or until death or liver transplantation (LT). The primary outcome in this study was 90-d LT-free mortality. Acute-on-chronic liver failure (ACLF) was assessed on admission and during 28-d hospitalization, according to the diagnostic criteria of the European Association for the Study of the Liver (EASL). Risk factors for death were analyzed with logistic regression model.
RESULTS In patients with cirrhosis and AD, the overall prevalence of AILD was 9.3% (242/2597). Prevalence of ACLF was significantly lower in AILD cases (14%) than those with all etiology groups with cirrhosis and AD (22.8%) (P < 0.001). Among 242 enrolled AILD patients, the prevalence rates of primary biliary cirrhosis (PBC), autoimmune hepatitis (AIH) and PBC-AIH overlap syndrome (PBC/AIH) were 50.8%, 28.5% and 12.0%, respectively. In ACLF patients, the proportions of PBC, AIH and PBC/AIH were 41.2%, 29.4% and 20.6%. 28-d and 90-d mortality were 43.8% and 80.0% in AILD-related ACLF. The etiology of AILD had no significant impact on 28-d, 90-d or 365-d LT-free mortality in patients with cirrhosis and AD in both univariate and multivariate analysis. Total bilirubin (TB), hepatic encephalopathy (HE) and blood urea nitrogen (BUN) were independent risk factors for 90-d LT-free mortality in multivariate analysis. The development of ACLF during hospitalization only independently correlated to TB and international normalized ratio.
CONCLUSION AILD was not rare in hospitalized patients with cirrhosis and AD in China, among which PBC was the most common etiology. 90-d LT-free mortality were independently associated with TB, HE and BUN.

Abstract
Objective: To understand the awareness of weight and waist circumference and their influencing factors among residents aged ≥18 years in China and provide a reference for the development of relevant prevention and treatment policies and evaluation of intervention effects. Methods: We selected 298 counties (districts) from the 31 provinces (autonomous regions and municipalities) which participated in the 2018 China Chronic Disease and Risk Factor Surveillance program and included 194 779 permanent residents aged ≥18 years. To obtain the demographic characteristics of the study population, we used a multi-stage stratified whole-group random sampling method, questionnaires, and physical measurements. In this study, 179 045 people who completed the survey and had complete information on weight and waist circumference awareness were used as the study subjects. The weight awareness rate and waist circumference awareness rate were calculated by gender stratification, age, urban-rural, and education level groups. A multi-factor logistic regression model was used to analyze the influencing factors related to weight and waist circumference awareness of residents aged ≥18 years. Results: The weight awareness rate of adult residents in China in 2018 was 45.4% (95%CI: 41.9%-48.9%), higher among men [46.2% (95%CI: 42.5%-49.8%)] than women [44.6% (95%CI: 41.1%-48.2%)], and in urban areas [54.3% (95%CI: 49.3%-59.3%)]. The highest weight awareness rate appeared in residents with low BMI grouping [49.9% (95%CI: 44.3%-55.6%)], and the weight awareness rate in residents with undiagnosed central obesity, hypertension, and diabetes was higher than that of residents with diagnosed diabetes, with statistically significant differences (P<0.05). The waist circumference awareness rate of adult residents was 11.6% (95%CI: 9.7%-13.4%), higher in women [12.8% (95%CI: 10.8%-14.8%)] than in men [10.3% (95%CI: 8.6%-12.0%)], higher in urban [14.6% (95%CI: 11.7%-17.4%)] than in rural [8.3% (95%CI: 6.5%-10.2%)], and the waist circumference awareness rate was higher among residents with confirmed diabetes than those with undiagnosed diabetes, with statistically significant differences (P=0.020). The difference was statistically significant (P<0.001). The weight and waist circumference awareness rate increased with education level and annual per capita household income. Multi-factor logistic regression analysis suggested that urban, highly educated, high per capita annual household income and health check-up residents may have higher weight and waist circumference awareness rates among adult residents in China. Conclusion: Less than half of the adult residents in China know their weight status, and only about one-tenth know their waist circumference. Rural residents, those with low education levels and low annual per capita household income, and those who are obese need to be given prioritized attention. The relevant government departments should strengthen the popularization of the importance of weight and waist circumference on health and improve the awareness of our residents about their waist circumference and weight.

Abstract
Objective: To explore the relationship between white matter lesions and clinical features and response of cerebral spinal fluid (CSF) tap test in patients with idiopathic normal pressure hydrocephalus(iNPH). Methods: Possible iNPH patients were enrolled from outpatients and inpatients in Peking Union Medical College Hospital between 2014 and 2019. All patients underwent detailed neuropsychological and walking assessments, CSF tap test, as well as head magnetic resonance imaging. The Fazekas score of white matter lesions, the fractional anisotropy (FA)and mean diffusivity (MD) values of regions of interest by means ofdiffusion tensor imaging (DTI) were compared between CSF tap test positive and negative response groups. The correlation between DTI parameters and clinical characteristics was analyzed. Results: Forty-three patients (29 male and 14 female, age range: 52-79 years] wererecruited.Compared with the negative group, patients in the positive group tended to have higher Fazekas score of periventricular white matter(U=108.00, P=0.03), higher MD value of the region near anterior horn of left lateral ventricles[(1.14±0.27)×10-9mm2/s vs (0.85±0.08) ×10-9mm2/s, P=0.003], lower FA value of the region near anterior horn of the right lateral ventricles[(0.20±0.07)vs(0.27±0.09), P=0.058], and higher MD value near the posterior horn of right lateral ventricle [(1.17±0.34)×10-9mm2/s vs (0.95±0.01)×10-9mm2/s, P=0.003]. FA and MD were significantly correlated with motor function, cognitive and functional scores, and iNPH grading scale (iNPHGS) scores(all P<0.05). Conclusions: The white matter lesions might be one of the pathogeneses of lNPH and apathological changewhich can be reversed by CSF drainage. More white matter lesions should not be the contraindication of CSF drainage surgery.

Abstract
The sensitive determination of the critical micelle concentration (CMC) of surfactants is very important for their practical application. Due to their good sensitivity and simple operation, pyrene and its derivatives have been widely used as fluorescent probes to detect the CMC. However, their virulent and poor water-soluble nature has limited their wide employment. In the present work, environmentally friendly amphiphilic carbon dots (Cdots) with dual-color emission and absolute quantum yield (PLQY) values higher than 50% have been fabricated through a solvothermal process, which could successfully serve as self-calibrative, ratiometric fluorescent probes to estimate the CMC of both non-ionic and ionic surfactants. This work not only provides a new strategy to design green ratiometric fluorescent probes for the CMC measurement of surfactants but also expands the application of Cdots in the colloidal field.

Abstract
Trophoblasts differentiate and form the placenta during pregnancy in a complex and finely orchestrated process, which is dependent on the establishment of maternal-fetal immune tolerance and the proper function of trophoblasts. Trophoblasts express HLA-C and non-classical HLA-Ib molecules (HLA-E, HLA-F, and HLA-G). Numerous studies have shown that the unique expression pattern of the HLA molecules is closely linked to the successful acceptance of allogeneic fetus by the mother during pregnancy. However, some controversies still exist concerning the exact expression and recognition patterns of HLA molecules in different trophoblast subpopulations and cell lines. Thus, we summarize three types of trophoblast subpopulations as well as the common trophoblast lineages. Then, the classification and structural characteristics of HLA molecules were elucidated. Finally, the presence of HLA-C and non-classical HLA-Ib molecules (HLA-E, HLA-F, and HLA-G) in various trophoblasts and cell lines, as well as their potential role in establishing and maintaining normal pregnancy were also discussed. Together, this review will help people comprehensively understand the complex immune interactions between maternal and fetal crosstalk during pregnancy and ultimately better understand the physiological and pathological etiologies of pregnancy.

Abstract
OBJECTIVE This study aims to analyze the clinical characteristics of pediatric acute lymphoblastic leukemia (ALL) complicated by pneumonia and the risk factors of severe cases to preliminarily construct a prediction model for ALL complicated by severe pneumonia. METHODS A retrospective analysis was carried out on the clinical data of children diagnosed with ALL complicated by pneumonia hospitalized at the Department of Pediatrics of the Affiliated Hospital of Southwest Medical University between January 2013 and December 2020. The risk factors of severe ALL complicated by pneumonia were investigated with logistic regression analysis, and the risk prediction model was constructed. RESULTS A total of 116 cases of pediatric ALL complicated by pneumonia were analyzed. There were 71 cases of mild pneumonia and 45 cases of severe pneumonia. The main clinical manifestations were cough in 112 cases and fever in 109. Pathogens were detected in 23 cases. Multiple regression factor analysis indicated that the use of hormones (OR 4.001, 95% CI: 1.505-10.632), neutropenia or agranulocytosis (OR 7.472, 95% CI: 2.710-20.602), hemoglobin (Hb) < 90 g/L (OR 3.270, 95% CI: 1.256~8.516), and C-reactive protein (CRP) >15 mg/L (OR 3.253, 95% CI: 1.209~8.751) were independent risk factors that were associated with severe pneumonia. Logistic regression was used to establish the risk prediction model of ALL with severe pneumonia. The p-value was 0.659. The area under the receiver operating characteristic curve was 0.851, and the sensitivity and specificity were 84.4 and 71.8%, respectively. CONCLUSION The development of severe pneumonia may be affected by the use of hormones, neutropenia or agranulocytosis, Hb < 90 g/L, and CRP > 15 mg/L. The prediction model based on the risk factors is effective, which can provide a reference for the clinical evaluation of acute lymphoblastic leukemia with severe pneumonia.

Abstract
Male reproductive infections are known to shape the immunological homeostasis of the testes, leading to male infertility. However, the specific pathogenesis of these changes remains poorly understood. Exosomes released in the inflammatory microenvironment are important in communication between the local microenvironment and recipient cells. Here, we aim to identify the immunomodulatory properties of inflammatory testes-derived exosomes (IT-exos) and explore their underlying mechanisms in orchitis. IT-exos were isolated using a uropathogenic Escherichia coli (UPEC)-induced orchitis model and confirmed that IT-exos promoted proinflammatory M1 activation with increasing expression of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in vitro. We further used small RNA sequencing to identify the differential miRNA profiles in exosomes and primary testicular macrophages (TMs) from normal and UPEC-infected testes, respectively, and identified that miR-155-5p was highly enriched in IT-exos and TMs from inflammatory testes. Further study of bone marrow derived macrophages (BMDMs) transfected with miR-155-5p mimic showed that macrophages polarized to proinflammatory phenotype. In addition, the mice that were administrated IT-exos showed remarkable activation of TM1-like macrophages; however, IT-exos with silencing miR-155-5p showed a decrease in proinflammatory responses. Overall, we demonstrate that miR-155-5p delivered by IT-exos plays an important role in the activation of TM1 in UPEC-induced orchitis. Our study provides a new perspective on the immunological mechanisms underlying inflammation-related male infertility.

Abstract
Programmed cell death-1 (PD-1) and T-cell immunoglobulin mucin-3 (Tim-3) are important immune checkpoint receptors that prevent an overreacted maternal immune response to fetal antigens during pregnancy. Disruption of complex immune regulation mechanisms is associated with adverse pregnancy outcomes, including preeclampsia (PE). Our recent study showed that the Tim-3 pathway was involved in the regulation of decidual macrophage polarization. Decidual macrophages polarized to the M1 phenotype may impair uterine vessel remodeling during placentation, accounting for the occurrence of PE. Co-blockade of the PD-1/Tim-3 pathway was shown to successfully control tumor growth in preclinical cancer models. However, the effects of activating both PD-1 and Tim-3 pathways as a combined intervention strategy in PE are never reported. Herein, we observed the skew of decidual macrophage polarization toward the M1 phenotype in patients with PE and lipopolysaccharide (LPS)-induced PE-like rat model. Moreover, we found that the activation of PD-1/Tim-3 pathway by using PD-L1 and Gal-9 fusion proteins could alleviate the manifestation of the LPS-induced PE-like rats and protect their offspring. Compared with the single intervention, the combination of PD-L1and Gal-9 fusion proteins exhibited obvious advantages in the relief of PE-like symptoms, trophoblast invasion, and fetal vascular development, indicating a synergistic effect of the activated PD-1/Tim-3 pathway. The in vitro study also revealed that the combined intervention using PD-L1 and Gal-9 fusion proteins inhibited the LPS-induced M1 macrophage polarization via the synergic activation of the ERK/GSK3β/β-catenin signaling pathway. Together, our findings provide the first evidence that simultaneous activation of PD-1/Tim-3 signaling pathways may have an optimal protective effect and serve as a new potential target for PE intervention.

Abstract
Background A bibliometric analysis was performed to reveal the current status of investigations in infectious diseases in patients with liver transplantation (LT) and to prioritize future research needs. Methods The present study comprehensively retrieved publications relevant to infectious diseases in LT recipients published between 2010 and 2020. The search was conducted on the Web of Science (WoS) database. A bibliometric analysis was conducted through machine learning and visualization tools, including VOSviewer, Bibliographic Item Co-Occurrence Matrix Builder, and Graphical Clustering Toolkit. Research hotspots and trends in the field were assessed, while the contributions and collaborations of countries, institutions, and authors were documented. Results A total of 691 publications were analyzed. Research output sharply increased in 2015, with a fast drop afterward. “Liver transplantation” was the most frequent keyword, with strong links to “hepatitis C virus” and “infection”. Study areas included risk factors of infectious diseases in LT recipients, pathogens causing post-transplantation infections, antibacterial therapy and prophylaxis for peritransplant infection complications, living donor LT, and pediatric LT. The efficacy and safety of direct-acting antivirals (DAAs) for hepatitis C virus (HCV) infection among liver transplant recipients has attracted recent research interest. Didier Samuel was the most productive author, while Xavier Forns was the top-cited author. Shanghai Jiao Tong University was the most productive contributor, and Gilead Sciences was the most cited organization. Moreover, the USA was the greatest contributor. Gastroenterology was the most cited journal, while Liver Transplantation was the most prolific journal. Conclusions This bibliometric analysis will better understand the research status of infectious complications in LT recipients and forecast future research trends. Priority should be given to identifying risk factors for peritransplantation infections and effective treatments against infectious complications in the coming years.

Abstract
Objective: To explore the influence of measurement sites on the diagnostic performance of coronary computed tomography angiography (CCTA) -derived instantaneous wave-free ratio (iFRCT) for coronary stenosis ischemia. Methods: A total of 44 patients, including 27 males and 17 females aged from 44 to 83 (59±90) years, who underwent coronary computed tomography angiography (CCTA) and invasive fractional flow reserve (FFR) in the Department of Radiology, Eastern Theater Command General Hospital from February 2009 to May 2018 were retrospectively collected. Based on CCTA images, iFRCT values at different locations (stenosis, proximal downstream of stenosis, 2 cm downstream of stenosis, 3 cm downstream of stenosis, and 4 cm downstream of stenosis) were calculated through fluid mechanics simulation. With invasive FFR≤0.80 as the reference standard, receiver operating characteristic (ROC) was used to analyze and evaluate the diagnostic performance of iFRCT in different sites. Bland-Altman and spearman correlation coefficient were used to analyze the consistency between iFRCT and invasive FFR. Intraclass correlation coefficient (ICC) and spearman correlation coefficient were used to test the repeatability of iFRCT. Results: iFRCT values at the proximal downstream of the stenosis (approximately 1 cm downstream of the stenosis) was superior to other measurement sites in the diagnosis of coronary ischemic specific stenosis. The threshold, area under the curve, sensitivity, specificity and accuracy of iFRCT at the stenosis were 0.91, 0.87 (95%CI:0.76~0.96), 82% (95%CI:48%~97%), 76% (95%CI:57%~88%) and 77% (95%CI: 63%~87%), respectively. Bland-Altman analysis showed that the mean differences between iFRCT and FFR at the proximal downstream of the stenosis was 0.07 (95%LoA: 0.06~0.09) and Spearman correlation coefficient was 0.53 (P<0.001). At the proximal downstream of the stenosis, the intraobserver ICC of iFRCT was 0.92 (95%CI: 0.85 ~0.95), the correlation coefficient was 0.85 (P<0.001); the interobserver ICC was 0.84 (95%CI: 0.60~0.94), correlation coefficient was 0.75 (P<0.001), demonstrating good repeatability between iFRCT and FFR. Conclusion: With the invasive FFR value as reference standard, iFRCT had a high diagnostic performance in detecting myocardial ischemia and the best measurement site was the proximal downstream of the stenosis.

Abstract
Objective: To investigate the value of spleen density in predicting the prognosis of patients with gastric cancer after radical gastrectomy. Methods: A total of 415 patients with gastric cancer who underwent radical resection in the Department of General Surgery, Affiliated Cancer Hospital of Zhengzhou University from January 2012 to December 2015 were retrospectively analyzed. Of the patients, there were 295 males and 120 femles with a median age of 59 years (range 28-83 years). The patients were divided into diffuse decreased spleen density group (DROSD) (spleen density≤43.0 HU, n=118) and non-diffuse decreased spleen density group (N-DROSD) (spleen density>43.0 HU, n=297) according to the density of spleen detected by computed tomography (CT). The receiver operating characteristic (ROC) curve was used to identify the checkpoint of spleen density in predicting the recurrence of the gastric cancer in those patients. The relationship with clinicopathological factors and prognosis in the two groups were further analyzed. Results: The optimal critical value of spleen density for predicting postoperative recurrence of gastric cancer was 43.0 HU, the area under the curve of ROC was 0.608, and the sensitivity and specificity was 84.9% and 40.4%, respectively. Spleen density was related to albumin, hemoglobin, neutrophil lymphocyte ratio (NLR) and tumor diameter in patients with gastric cancer (all P<0.05). The 5-year disease-free survival rate and 5-year disease-specific survival rate of all the patients was 45.5% and 50.1%, respectively. Univariate survival analysis showed that age, NLR, PLR, tumor location, tumor diameter, Lauren classification, TNM stage, nerve invasion, vascular invasion, DROSD and adjuvant chemotherapy were all related to the 5-year disease-free survival rate (all P<0.05); Age, NLR, tumor location, tumor diameter, Lauren classification, TNM stage, nerve invasion, vascular invasion, DROSD and adjuvant chemotherapy were all related to the 5-year disease-specific survival rate (all P<0.05). Multivariate survival analysis showed that high NLR level (HR=1.501, 95%CI: 1.136-1.984), late TNM stage (HR=2.559, 95%CI: 1.850-3.539), DROSD (HR=2.093, 95%CI: 1.571-2.788) and no adjuvant chemotherapy (HR=1.583, 95%CI: 1.204-2.083) were independent risk factor for the 5-year disease-free survival rate (all P<0.05). Late TNM stage (HR=1.938, 95%CI: 1.395-2.692), DROSD (HR=1.566, 95%CI: 1.180-2.078) and no adjuvant chemotherapy (HR=1.336, 95%CI: 1.016-1.758) were independent risk factors for the 5-year disease-free survival rate (all P<0.05). For stage Ⅰ patients, the 5-year disease-free survival rates of DROSD group and N-DROSD group was 78.6% and 83.7%, respectively; and the 5-year disease-specific survival rates was 85.7% and 89.8%, respectively (both P>0.05). For stage Ⅱ and Ⅲ patients, the 5-year disease-free survival rates of DROSD group and N-DROSD group was 15.4% and 48.8%, respectively, and the 5-year disease-specific survival rates was 17.3% and 54.0%, respectively (all P<0.001). Conclusion: As an imaging evaluation method, spleen density is a new tool, which can be used as a prognostic indicator for gastric cancer patients.

Abstract
Varicocele is one of the most important causes of male infertility, as this condition leads to a decline in sperm quality. It is generally believed that the presence of varicocele induces an increase in reactive oxygen species levels, leading to oxidative stress and sperm apoptosis; however, the specific pathogenic mechanisms affecting spermatogenesis remain elusive. Prokineticin 2 (PK2), a secretory protein, is associated with multiple biological processes, including cell migration, proliferation, and apoptosis. In the testis, PK2 is expressed in spermatocytes under normal physiological conditions. To investigate the role of PK2 in varicocele, a rat varicocele model was established to locate and quantify the expression of PK2 and its receptor, prokineticin receptor 1 (PKR1), by immunohistochemistry and quantitative real-time PCR assays (qPCR). Moreover, H2O2 was applied to mimic the oxidative stress state of varicocele through coculturing with a spermatocyte-derived cell line (GC-2) in vitro, and the apoptosis rate was detected by flow cytometry. Here, we illustrated that the expression levels of PK2 and PKR1 were upregulated in the spermatocytes of the rat model. Administration of H2O2 stimulated the overexpression of PK2 in GC-2. Transfection of recombinant pCMV-HA-PK2 into GC-2 cells promoted apoptosis by upregulating cleaved-caspase-3, caspase-8, and B cell lymphoma 2-associated X; downregulating B cell lymphoma 2; and promoting the accumulation of intracellular calcium. Overall, we revealed that the varicocele-induced oxidative stress stimulated the overexpression of PK2, leading to apoptosis of spermatocytes. Our study provides new insight into the mechanisms underlying oxidative stress-associated male infertility and suggests a novel therapeutic target for male infertility.

Abstract
Objective: To investigate the risk factors for death in children with acute necrotizing encephalopathy (ANE) in pediatric intensive care unit (PICU). Methods: This was a multicenter retrospective study. Thirty-nine children with ANE were from PICUs in 4 centers from December 1, 2014 to December 1, 2020. The 4 participating centers were Beijing Children's Hospital, Shengjing Hospital of China Medical University, Hebei Children's Hospital, and Bao'an Maternity & Child Health Hospital. Patients were divided into survival and non-survival groups by the outcome at discharge, and the differences in clinical data between the two groups were compared. Risk factors for death in children with ANE and the odds ratios (OR) were analyzed by univariable Logistic regression. Results: Thirty-nine children with ANE were included. There were 18 males and 21 females. The median onset age was 30 months. The mortality at discharge was 41% (16/39). The onset age of most patients (74%, 29/39) was younger than 4 years old. Influenza virus was the most common precursor infection (80%, 20/25). Patients with shock at PICU admission were more common in the non-survival group (12/16 vs. 17% (4/23), P=0.001). Glasgow coma score (GCS) at PICU admission was significantly lower in the non-survival group than survival group (3 (3, 6) vs. 6 (5, 7), Z=-2.598, P=0.009). The optimal cut-off value was 4. The proportion of patients with GCS ≤ 4 at PICU admission was higher in the non-survival group (10/16 vs. 22% (5/23), P=0.018). ANE severity score (ANE-SS) at PICU admission was significantly higher in the non-survival group (5 (2, 6) vs. 2 (1, 4), Z=-2.436, P=0.015). The proportion of patients with high risk ANE-SS was higher in non-survival group than the survival group (9/16 vs. 22% (5/23), P=0.043). The proportion of application of high-dose methylprednisolone (20 mg/(kg·d)) was significantly higher in survival group than non-survival group (43% (10/23) vs. 1/13, P=0.031). Univariable Logistic regression indicated that risk factors for death in children with ANE were shock (OR=14.250, 95%CI 2.985-68.018, P=0.001), GCS≤4 (OR=6.000, 95%CI 1.456-24.733, P=0.013) and high risk ANE-SS (OR=4.629, 95%CI 1.142-18.752, P=0.032) at PICU admission. Conclusions: ANE usually occurs in children under 4 years old after influenza infection. Shock, GCS≤4 and high risk ANE-SS at PICU admission were risk factors for death in children with ANE. High-dose methylprednisolone may improve the prognosis of children with ANE.
