Abstract
Objective: To summarize the clinical characteristics and prognosis of severe infant botulism and evaluate the therapeutic effect of botulinum antitoxin in the pediatric intensive care unit (PICU). Methods: The clinical data of 8 cases diagnosed with infantile botulism were retrospectively analyzed in the PICU of Beijing Children's Hospital from October 2019 to August 2023. Data of basic demographic information, clinical manifestations, laboratory tests, treatment and prognosis of each child were collected and analyzed using descriptive statistical methods. Results: Eight laboratory-confirmed cases of infant botulism were included in this study, all of which were male infants with an age of 6.0 (3.3,6.8) months. Three of the children were from Inner Mongolia Autonomous Region, 2 of them were from Hebei, and the other 3 were from Beijing, Shandong and Xinjiang Uyghur Autonomous Region, respectively. All the patients were previously healthy. In 4 of these cases, the possible cause was the ingestion of either honey and its products or sealed pickled food by the mother or child before the onset of the disease. The first symptom was poor milk intake (4 cases), followed by shallow shortness of breath (7 cases), limb weakness (7 cases) and so on. The typical signs were bilateral dilated pupils (8 cases) and decreased limb muscle strength (8 cases). The main subtype was type B (7 cases), and only 1 case was classified as type A. Six of the children were treated with antitoxin therapy for a duration of 24 (19, 49) d. Seven of them had invasive mechanical ventilation. All the patients survived upon discharge with a follow-up period of 29 d to 3 years and 8 months. Six patients had fully recovered, and 2 recently discharged patients were gradually recovering. Conclusions: For infants with suspected contact or ingestion of botulinum and presented with bilateral pupillary paralysis, muscle weakness and clear consciousness, the stool should be collected for diagnostic testing using a mouse bioassay as soon as possible. Type B was the most common type. The antitoxin treatment was effectiveness and the prognosis was well.

Abstract
With the increasing incidence of esophagogastric junction carcinoma, the application rate of proximal gastrectomy has been rising annually. There is a wide variety of methods for digestive tract reconstruction after proximal gastrectomy, and some of these reconstruction methods have been introduced relatively recently, with limited clinical experience, which led to a lack of standardization. Such a situation will inevitably result in inconsistent clinical outcomes of proximal gastrectomy with digestive tract reconstruction. To promote the standardization of digestive tract reconstruction after proximal gastrectomy, improve the clinical efficacy of proximal gastrectomy, and reduce the occurrence of postoperative complications, this article elaborates on the indications, surgical steps and technical points of the four methods after proximal gastrectomy recommended by the "Chinese consensus on digestive tract reconstruction after proximal gastrectomy (2020 edition)", such as double tract, side overlap, double flaps and gastric tube reconstruction, providing guidance for the application of digestive tract reconstruction after proximal gastrectomy.

Abstract
BACKGROUND There is no consensus on whether adjuvant chemotherapy (AC) is effective for hepatoid adenocarcinoma of the stomach (HAS). The aim of this study was to investigate the relationship between AC and the long-term prognosis of patients with HAS. METHODS The clinicopathological data of 239 patients with primary HAS who underwent radical surgery from April 1, 2004 to December 31, 2019 in 14 centers in China were retrospectively analyzed. Patients were divided into the AC group (127 patients) and the nonadjuvant chemotherapy (NAC) group (112 patients). RESULTS Kaplan‒Meier (KM) analysis showed that there were no significant differences in the 1-year3-year overall survival rate (OS) and 1-year, 3-year recurrence-free survival rate (RFS) between the AC group and the NAC group (1-year OS: 85.6% vs. 79.8%, 3-year OS: 59.8% vs. 62.4%, 1-year RFS: 69.8% vs. 74.4%, 3-year RFS: 57.2% vs. 55.9%, all P > 0.05). The subpopulation treatment effect pattern plots (STEPP) did not show treatment heterogeneity of AC in patients with HAS. The proportions of local recurrence and metastasis sites in the two groups were similar. Although the smoothed hazard curves of the NAC and AC groups crossed, the peak hazard time was later in the AC group (5.9 and 4.7 months), and the peak hazard rate was lower (0.032 and 0.038, P = 0.987). CONCLUSION The current AC regimen may not significantly improve the survival of patients with HAS after radical surgery.

Abstract
Objective: To investigate the diagnostic value of anti-Sa antibody and anti-carbonylated protein (CarP) antibody for rheumatoid arthritis (RA). Methods: A retrospective selection of 180 patients with RA who came to Qinghai Provincial People's Hospital from September 2022 to February 2023. Grouped according to the Disease Activity Score of 28 joints (DAS28), 101 of them were patients with RA in high activity (RAH group), 24 males and 77 females, aged 18-79 (53.2±12.2), and 79 patients with RA in low activity (RAL group), 23 males and 56 females, aged 24-78 (49.0±12.9).A total of 90 patients with other autoimmune diseases in the hospital in the same period were choosed as the other immune disease group, and 90 healthy physical examiners were as the healthy control group. The levels of serum anti-Sa and anti-CarP antibodies were measured by ELISA, RF by immunoscattering turbidimetry, anti-CCP by chemiluminescence, and ESR by Weil's method in four groups of patients. The area under the subject operating characteristic (ROC) curve (AUC) was applied to assess the sensitivity and specificity of each index alone or in combination for the diagnosis of RA. Results: In the RAH group, RAL group, other immune disease group, and healthy control group, the RF levels were 117.6 (61.0, 161.1), 92.7 (48.1, 92.7), 10.1 (5.3, 24.6), and 8.1 (6.0, 12.8) U/ml, anti-CCP antibody levels were 202.7 (67.1, 594.4), 212.9 (98.3, 416.2), 9.4 (6.6, 11.8), 1.9 (0.8, 4.9) U/ml, anti-Sa antibody levels were 305.3 (120.4, 614.9), 235.8 (161.6, 336.9), 123.9 (41.8, 240.5), 165.1 (71.1, 237.5) U/ml, and anti-CarP antibody levels were 11.7 (7.9, 21.6), 5.2 (3.3, 7.7), 5.1 (3.9, 6.5), and 5.8 (3.8, 7.5) mg/L, respectively, and their differences were statistically significant (all P<0.001). The level of anti-CarP antibody was higher in the RAH group than in the RAL group (P<0.001), and the difference in anti-Sa antibody was not statistically significant (P>0.05). The critical value of anti-Sa antibody at 181.45 μg/L showed a sensitivity of 67.2%, specificity of 65.6% and AUC of 0.710 (95%CI: 0.645-0.775); The sensitivity was 52.8% and the specificity was 88.9% with an AUC of 0.706 (95%CI: 0.646-0.766) at a critical value of 7.98 U/ml for the anti-CarP antibody. The AUC for the combined RF, anti-CCP antibody and anti-CarP antibody assay was 0.986 (95%CI: 0.977-0.996). Conclusion: Anti-CarP antibody is clinically significant in distinguishing active RA. RF, anti-CCP, and anti-CarP antibodies can be detected together with high AUC results, suggesting the potential for developing an improved method for diagnosing RA.

Abstract
Objective: To explore the relationship and dynamic changes between virological markers and hepatic pathological damage due to host anti-hepatitis B virus (HBV) immunity in the natural course of disease in chronic HBV infected patients. Methods: Two hundred and thirty-eight adult chronic HBV-infected patients who underwent liver biopsy from January 2016 to June 2022 in Taizhou Hospital, Zhejiang Province, were retrospectively selected. General clinical data such as age, gender, platelets, ALT, AST, albumin, HBV DNA, qHBsAg, HBeAg, and liver pathology diagnostic indexes such as the grade of liver necroinflammation and liver fibrotic stages of the patients were collected. The patients were grouped according to HBeAg status, and subgrouped according to different grades of liver necroinflammation and different HBV DNA loads. Statistical analyses were performed to compare the differences in HBV virologic marker levels between the groups, and the correlation between them and the indicators of hepatic inflammatory injury, such as ALT,AST, and the grade of liver necroinflammation in the patients. Results: The levels of HBV virological markers in HBeAg-positive patients with moderate or higher liver necroinflammatory grade (G≥2) were significantly lower than those with mild (no) liver necroinflammatory grade (G < 2) (P < 0.01); whereas the opposite trend was observed in HBeAg-negative patients, with the levels of HBV DNA, and qHBsAg in the G≥2 subgroup being significantly higher than those in the G < 2 subgroup (P < 0.01). Correspondingly, HBV DNA level and qHBsAg showed weak to moderately strong negative correlation with liver necroinflammatory grade and AST which was an indicator of hepatic inflammatory injury in HBeAg-positive patients (P < 0.05); whereas in HBeAg-negative patients, they showed weak to moderately strong positive correlation with hepatic inflammatory activity and ALT, AST (P < 0.001), in which qHBsAg showed only a weak positive correlation with patients' liver necroinflammatory grade (P = 0.003). Further subgroup analyses of HBeAg-positive patients according to whether the HBV DNA level was > 2×10(6) IU/ml showed weak to moderate negative correlations between HBV virological markers and liver necroinflammatory grade as well as ALT and AST in the subgroup of patients with HBV DNA > 2×10(6) IU/ml (P < 0.05); however, the negative correlation disappeared in patients who were still HBeAg positive and had HBV DNA ≤ 2×10(6) IU/ml. Moreover, HBV DNA and ALT, HBeAg and AST showed moderate positive correlation (P < 0.05). Conclusion: We speculate that the activation of host anti-HBV immunity can efficiently inhibit HBV replication by targeting the infected hepatocytes, but only in the early phase of disease progression in HBeAg positive patients with HBV DNA high (> 2×10(6) IU/ml).

Abstract
Aroma is an important attribute of infant formula (IF). In this study, 218 volatiles and 62 odor-active compounds were detected from IF by dynamic headspace sampling combined with comprehensive 2-dimensional gas chromatography-olfactometry-mass spectrometry. Aldehydes and ketones were determined as the most abundant odor-active compounds. Among them, the contents of pentanal and hexanal were the most abundant, while 1-octen-3-one had the highest flavor dilution factor and odor activity value in most of the IF. Sensory evaluation and electronic nose analysis showed that the skimming process, the fatty acid composition, and powdered or liquid milk base used for the production of IF may be important factors resulting in their differences in aroma profiles and compounds. These differences were assumed to be mainly ascribed to the Maillard reaction and lipid oxidation, which were largely influenced by the temperature and water activity.

Abstract
INTRODUCTION AND IMPORTANCE Neurofibromatosis Type 1 (NF1) is a rare autosomal dominant genetic disorder that affects multiple organs and systems, including the nervous system, integumentary system, and connective tissues. Spontaneous hemothorax occurs infrequently in patients with NF1 and is associated with high fatality rates. However, it is commonly overlooked or misdiagnosed. CASE PRESENTATION We present the case of a 29-year-old woman with NF1 who complained of chest pain and was detected with hemothorax on radiographic examination. No bleeding sites were identified following thrombectomy. The patient's condition deteriorated with conservative treatment over nine days, posing a potentially life-threatening risk. After a diagnostic evaluation using computerized tomography angiography (CTA) and digital subtraction angiography (DSA) of the neck vasculature, the patient was diagnosed with spontaneous rupture of the vertebral artery (VA) and subclavian artery (SuA) aneurysm. Following a multidisciplinary discussion and extensive investigations, the patient underwent successful endovascular treatment. A VIABAHN covered stent was implanted in the left SuA to overlay the emergent orifice. The endovascular treatment challenge due to the inaccessible of the proximal of left VA. To prevent retrograde flow into the VA aneurysm, the coils were used to embolize the left VA via the right vertebral artery-basilar artery (VA-BA) passage. The patient was alive at the 5-year follow-up without further complications. CLINICAL DISCUSSION The CTA examination led to the diagnosis of vascular rupture due to NF1, and endovascular treatment was performed to occlude the vascular lumen. There have been no recurrences during the five-year follow-up period. CONCLUSION Vasculopathy is the second leading cause of death in patients with NF1 after malignancy. Early diagnosis of spontaneous hemothorax in patients with NF1 is crucial, as misdiagnosis can result in missed treatment opportunities. CTA plays a vital role in preliminarily diagnosing the cause of spontaneous hemothorax, while endovascular treatment offers a new therapeutic option for such patients.

Abstract
Pulmonary hypertension (PH) is a pathophysiological condition of increased pulmonary circulation vascular resistance due to various reasons, which mainly leads to right heart dysfunction and even death, especially in critically ill patients. Although drug interventions have shown some efficacy in improving the hemodynamics of PH patients, the mortality rate remains high. Hence, the identification of new targets and treatment strategies for PH is imperative. Heparanase (HPA) is an enzyme that specifically cleaves the heparan sulfate (HS) side chains in the extracellular matrix, playing critical roles in inflammation and tumorigenesis. Recent studies have indicated a close association between HPA and PH, suggesting HPA as a potential therapeutic target. This review examines the involvement of HPA in PH pathogenesis, including its effects on endothelial cells, inflammation, and coagulation. Furthermore, HPA may serve as a biomarker for diagnosing PH, and the development of HPA inhibitors holds promise as a targeted therapy for PH treatment.

Objective: To analyze the influencing factors of futile recanalization after endovascular therapy (EVT) in acute ischemic stroke patients with large vessel occlusions (AIS-LVO). Methods: AIS-LVO patients who underwent EVT with successful recanalization between January 2019 and December 2021 in Neurovascular Center of Changhai Hospital of Naval Medical University were retrospectively selected. Modified Rankin scale (mRS) score 3 months after EVT was used as the prognostic evaluation index, and patients with mRS scores≤2 were classified as the meaningful recanalization group and mRS scores 3-6 as the futile recanalization group. The risk factors, National Institutes of Health stroke scale (NIHSS) score, Glasgow coma scale (GCS) score, Alberta Stroke Program Early CT (ASPECT) score, core infarct volume, etc. in both groups were analyzed, and the influencing factors of futile recanalization after EVT were analyzed by multivariate logistic regression. Continuous variables that do not conform to the normal distribution are represented by [M(Q1,Q3)]. Results: A total of 368 patients meeting the inclusion criteria were collected, including 228 males and 140 females, and aged 68 (61, 77) years. There are 196 patients and 172 patients in the meaningful recanalization and futile recanalization groups, respectively, with the rate of futile recanalization 3 months after EVT of 46.74% (172/368). Comparing the general information and risk factors between the two groups found that the age of patients in the futile recanalization group [71 (65, 79) years] was higher than that in the meaningful recanalization group [65 (59, 72) years]. The baseline NIHSS score [18 (14, 22)] and the rate of not achieving modified Thrombolysis in Cerebral Ischemia grade 3 (mTICI 3) reperfusion (36.1%) were higher in the futile recanalization group than those in the meaningful recanalization group [12 (7, 17) and 19.9%]. The baseline GCS score [11 (9, 13)] was lower in the futile recanalization group than that in the meaningful recanalization group [14 (11, 15)]. The core infarct volume in the futile recanalization group [28 (7, 65) ml] was larger than that in the meaningful recanalization group [6 (0, 17) ml]. The ASPECT score [7 (5, 9)] was lower in the futile recanalization group than that in the meaningful recanalization group [9 (7, 10)]. In addition, the proportion of hypertension, atrial fibrillation, general anesthesia, and symptomatic intracranial hemorrhage was higher in the futile recanalization group (all P<0.05). The time from symptom onset to puncture and from symptom onset to reperfusion was longer in the futile recanalization group (both P<0.05). There were statistically significant differences in trial of Org 10172 in acute stroke treatment (TOAST) classification and the site of occluded blood vessels between the two groups (both P<0.05). Multivariate logistic regression indicated that age ≥80 years(OR=1.935,95%CI: 1.168-3.205), baseline NIHSS score (OR=1.999,95%CI: 1.202-3.325), GCS score (OR=2.299,95%CI: 1.386-3.814), previous stroke history (OR=1.977,95%CI: 1.085-3.604), general anesthesia (OR=1.981,95%CI: 1.143-3.435), not achieving grade 3 recanalization (OR=2.846, 95%CI: 1.575-5.143), ASPECT score<6 (OR=2.616, 95%CI: 1.168-5.857), and core infarct volume>70 ml (OR=2.712, 95%CI: 1.130-6.505) were risk factors for futile recanalization. Conclusion: Age≥80 years, previous stroke history, baseline NIHSS score≥20, GCS score≤8, general anesthesia, ASPECT score<6, core infarct volume>70 ml, and failure to achieve Grade 3 recanalization are independent influencing factors for futile recanalization after endovascular therapy in AIS-LVO patients.

Abstract
Sepsis-related acute kidney injury (S-AKI) is a common and significant complication of sepsis in critically ill patients, which can often only be treated with antibiotics and medications that reduce S-AKI symptoms. The precise mechanism underlying the onset of S-AKI is still unclear, thus hindering the development of new strategies for its treatment. Therefore, it is necessary to explore the pathogenesis of S-AKI to identify biomarkers and therapeutic targets for its early diagnosis and treatment. Heparanase (HPA), the only known enzyme that cleaves the side chain of heparan sulfate, has been widely studied in relation to tumor metabolism, procoagulant activity, angiogenesis, inflammation and sepsis. It has been reported that HPA plays an important role in the progression of S-AKI. The aim of the present review was to provide an overview of the function of HPA in S-AKI and to summarize its underlying molecular mechanisms, including mediating inflammatory response, immune response, autophagy and exosome biogenesis. It is anticipated that emerging discoveries about HPA in S-AKI will support HPA as a potential biomarker and therapeutic target to combat S-AKI.

Abstract
Acute respiratory distress syndrome (ARDS) is the most common respiratory disease in ICU. Although there are many treatment and support methods, the mortality rate is still high. The main pathological feature of ARDS is the damage of pulmonary microvascular endothelium and alveolar epithelium caused by inflammatory reaction, which may lead to coagulation system disorder and pulmonary fibrosis. Heparanase (HPA) plays an significant role in inflammation, coagulation, fibrosis. It is reported that HPA degrades a large amount of HS in ARDS, leading to the damage of endothelial glycocalyx and inflammatory factors are released in large quantities. HPA can aggrandize the release of exosomes through syndecan-syntenin-Alix pathway, leading to a series of pathological reactions; at the same time, HPA can cause abnormal expression of autophagy. Therefore, we speculate that HPA promotes the occurrence and development of ARDS through exosomes and autophagy, which leads to a large amount of release of inflammatory factors, coagulation disorder and pulmonary fibrosis. This article mainly describes the mechanism of HPA on ARDS.

Abstract
BACKGROUND Through significant advances in the treatment of peripheral arterial occlusive disease, acute ischemia of the lower extremity is still associated with significant morbidity, limb threat and mortality. The two main causes of acute ischemia in lower extremities are arterial embolism and atherosclerotic arteries. Timely recognition and treatment of acute limb ischemia in emergency situations is essential in order to minimize the duration of ischemia.
AIM To investigate the application effect of angiojet thrombolysis in the treatment of acute lower extremity arterial embolization.
METHODS Sixty-two patients with acute lower extremity arterial embolization admitted to our hospital from May 2018 to May 2020 were selected. Among them, the observation group (twenty-eight cases) had received angiojet thrombolysis, and the control group (thirty-four cases) had received femoral artery incision and thrombectomy. After thrombus clearance, significant residual stenosis of the lumen was combined with balloon dilation and/or stent implantation. When the thrombus removal was not satisfactory, catheter-directed thrombolysis was performed. The incidence of postoperative complications, recurrence rate and recovery of the two groups were compared.
RESULTS There were no significant differences in postoperative recurrence (target vessel reconstruction rate), anklebrachial index and the incidence of postoperative complications between the two groups (P > 0.05); there were statistically significant differences in postoperative pain score and postoperative rehabilitation between the two groups (P < 0.05).
CONCLUSION The application of angiojet in the treatment of acute lower limb artery thromboembolism disease is safe and effective, minimally invasive, quicker recovery after operation, less postoperative complications, which is more suitable for the treatment of femoral popliteal arterial thromboembolism lesions. If the thrombus removal is not satisfactory, the combination of coronary artery aspiration catheter and catheterized directed thrombolysis can be used. Balloon dilation and stent implantation can be considered for obvious lumen stenosis.

Abstract
BACKGROUND Roux-en-Y (R-Y) anastomoses have been widely used in distal gastrectomy, while the incidence of Roux stasis syndrome remains common. Uncut R-Y anastomosis maintains the neuromuscular continuity, thus avoiding the ectopic pacemaker of the Roux limb and reducing the occurrence of Roux stasis. However, retrospective studies of Uncut R-Y anastomosis remain scarce and randomized controlled trials have not been reported. METHODS We conducted a randomized controlled trial to compare the surgical safety, nutritional status, and postoperative quality of life (QOL) between uncut and classic Roux-en-Y (R-Y) reconstruction patients. Patients with Stage I gastric cancer were randomly enrolled and underwent laparoscopic distal gastrectomy followed by uncut or classic R-Y reconstruction. Body mass index and blood test were used to evaluate the nutritional status. QOL was evaluated using European Organization for Research and Treatment of Cancer QOL Questionnaire (STO22) and laboratory examinations at postoperative month (POM) 3, 6, 9, and 12. Computed tomography scanning was used to evaluate the skeletal muscle index (SMI) at POM 6 and 12. Endoscopy was performed at POM 12. RESULTS Operation time, blood loss, time to recovery, complication morbidities, and overall survival were similar between the two groups. Compared with the classic R-Y group, the uncut R-Y group displayed a significantly decreased QOL at POM 9, possibly due to loop recanalization, determined to be occupied 34.2% of the uncut R-Y group. Post-exclusion of recanalization, the QOL was still higher in the classic R-Y group than in the uncut R-Y group, despite their hemoglobin and total protein levels being better than those in the classic R-Y group. Preoperative pre-albumin level and impaired fasting glycemia significantly correlated with the postoperative recanalization. CONCLUSION We found no significant benefit of uncut over classic R-Y reconstruction which challenges the superiority of the uncut R-Y reconstruction.

Abstract
BACKGROUND An accurate recurrence risk assessment system and surveillance strategy for hepatoid adenocarcinoma of the stomach (HAS) remain poorly defined. This study aimed to develop a nomogram to predict postoperative recurrence of HAS and guide individually tailored surveillance strategies. METHODS The study enrolled all patients with primary HAS who had undergone curative-intent resection at 14 institutions from 2004 to 2019. Clinicopathologic variables with statistical significance in the multivariate Cox regression were incorporated into a nomogram to build a recurrence predictive model. RESULTS The nomogram of recurrence-free survival (RFS) based on independent prognostic factors, including age, preoperative carcinoembryonic antigen, number of examined lymph nodes, perineural invasion, and lymph node ratio, achieved a C-index of 0.723 (95% confidence interval [CI], 0.674-0.772) in the whole cohort, which was significantly higher than those of the eighth American Joint Committed on Cancer (AJCC) staging system (C-index, 0.629; 95% CI, 0.573-0.685; P < 0.001). The nomogram accurately stratified patients into low-, middle-, and high-risk groups of postoperative recurrence. The postoperative recurrence risk rates for patients in the middle- and high-risk groups were respectively 3 and 10 times higher than for the low-risk group. The patients in the middle- and high-risk groups showed more recurrence and metastasis, particularly multiple site metastasis, within 36 months after the operation than those in the low-risk group (low, 2.2%; middle, 8.6%; high, 24.0%; P = 0.003). CONCLUSIONS The nomogram achieved good prediction of postoperative recurrence for the patients with HAS after radical resection. For the middle- and high-risk patients, more active surveillance and targeted examination methods should be adopted within 36 months after the operation, particularly for liver and multiple metastases.

Abstract
BACKGROUND Meeting 24-h movement guidelines for children and adolescents has been associated with improved health indicators. However, the literature examining adherence to 24-h movement guidelines among Chinese children and adolescents with intellectual disability (ID) remains lacking. This study aims to investigate the prevalence of meeting the 24-h movement guidelines and its socio-demographic correlates for this population. METHODS The sample includes 319 Chinese students with ID. Accelerometers are used to measure moderate-to-vigorous physical activity time and sleep duration. Questionnaires are adopted to measure screen time (ST) and demographic factors. Associations among socio-demographic factors, body mass index and 24-h movement are analysed by using multivariable logistic regressions. RESULTS The proportions of participants who meet none, moderate-to-vigorous physical activity, ST, sleep duration and all three recommendations are 8.15%, 33.54%, 54.23%, 75.55% and 17.55%, respectively. In general, multivariable logistic regression analysis indicates that older participants are less likely to meet the ST guidelines [odds ratio (OR): 0.931; 95% confidence interval (CI): 0.869-0.998] and more likely to meet the sleep guidelines (OR: 1.106; 95% CI: 1.016-1.204) than younger individuals. Participants with moderate ID are less likely to meet the sleep guidelines (OR: 0.345; 95% CI: 0.140-0.850) than those with profound ID. Individuals from families with middle-income (OR: 0.434; 95% CI: 0.226-0.836) and high-income (OR: 0.219; 95% CI: 0.080-0.605) levels were less likely to meet the physical activity guidelines than those from low-income families. Furthermore, participants from high-income families were less likely to meet ST (OR: 0.426; 95% CI: 0.187-0.969) and all three movement guidelines (OR: 0.083; 95% CI: 0.010-0.659) than those in the low household income groups. CONCLUSIONS Interventions that improve the health-related behaviours of children and adolescents with ID are needed, particularly those that target their increased engagement in physical activity.

Abstract
Inorganic superionic conductors possess high ionic conductivity and excellent thermal stability but their poor interfacial compatibility with lithium metal electrodes precludes application in all-solid-state lithium metal batteries1,2. Here we report a LaCl3-based lithium superionic conductor possessing excellent interfacial compatibility with lithium metal electrodes. In contrast to a Li3MCl6 (M = Y, In, Sc and Ho) electrolyte lattice3-6, the UCl3-type LaCl3 lattice has large, one-dimensional channels for rapid Li+ conduction, interconnected by La vacancies via Ta doping and resulting in a three-dimensional Li+ migration network. The optimized Li0.388Ta0.238La0.475Cl3 electrolyte exhibits Li+ conductivity of 3.02 mS cm-1 at 30 °C and a low activation energy of 0.197 eV. It also generates a gradient interfacial passivation layer to stabilize the Li metal electrode for long-term cycling of a Li-Li symmetric cell (1 mAh cm-2) for more than 5,000 h. When directly coupled with an uncoated LiNi0.5Co0.2Mn0.3O2 cathode and bare Li metal anode, the Li0.388Ta0.238La0.475Cl3 electrolyte enables a solid battery to run for more than 100 cycles with a cutoff voltage of 4.35 V and areal capacity of more than 1 mAh cm-2. We also demonstrate rapid Li+ conduction in lanthanide metal chlorides (LnCl3; Ln = La, Ce, Nd, Sm and Gd), suggesting that the LnCl3 solid electrolyte system could provide further developments in conductivity and utility.

Abstract
BACKGROUND Remnant gastric cancer (GC) is defined as GC that occurs five years or more after gastrectomy. Systematically evaluating the preoperative immune and nutritional status of patients and analyzing its prognostic impact on postoperative remnant gastric cancer (RGC) patients are crucial. A simple scoring system that combines multiple immune or nutritional indicators to identify nutritional or immune status before surgery is necessary.
AIM To evaluate the value of preoperative immune-nutritional scoring systems in predicting the prognosis of patients with RGC.
METHODS The clinical data of 54 patients with RGC were collected and analyzed retrospectively. Prognostic nutritional index (PNI), controlled nutritional status (CONUT), and Naples prognostic score (NPS) were calculated by preoperative blood indicators, including absolute lymphocyte count, lymphocyte to monocyte ratio, neutrophil to lymphocyte ratio, serum albumin, and serum total cholesterol. Patients with RGC were divided into groups according to the immune-nutritional risk. The relationship between the three preoperative immune-nutritional scores and clinical characteristics was analyzed. Cox regression and Kaplan–Meier analysis was performed to analyze the difference in overall survival (OS) rate between various immune-nutritional score groups.
RESULTS The median age of this cohort was 70.5 years (ranging from 39 to 87 years). No significant correlation was found between most pathological features and immune-nutritional status (P > 0.05). Patients with a PNI score < 45, CONUT score or NPS score ≥ 3 were considered to be at high immune-nutritional risk. The areas under the receiver operating characteristic curves of PNI, CONUT, and NPS systems for predicting postoperative survival were 0.611 [95% confidence interval (CI): 0.460–0.763; P = 0.161], 0.635 (95%CI: 0.485–0.784; P = 0.090), and 0.707 (95%CI: 0.566–0.848; P = 0.009), respectively. Cox regression analysis showed that the three immune-nutritional scoring systems were significantly correlated with OS (PNI: P = 0.002; CONUT: P = 0.039; NPS: P < 0.001). Survival analysis revealed a significant difference in OS between different immune-nutritional groups (PNI: 75 mo vs 42 mo, P = 0.001; CONUT: 69 mo vs 48 mo, P = 0.033; NPS: 77 mo vs 40 mo, P < 0.001).
CONCLUSION These preoperative immune-nutritional scores are reliable multidimensional prognostic scoring systems for predicting the prognosis of patients with RGC, in which the NPS system has relatively effective predictive performance.

Abstract
Objective: To assess the clinical characteristics and prognosis of patients with SIL-TAL1-positive T-cell acute lymphoblastic leukemia (T-ALL) . Methods: The clinical data of 19 SIL-TAL1-positive T-ALL patients admitted to the First Affiliated Hospital of Soochow University between January 2014 and February 2022 were retrospectively computed and contrasted with SIL-TAL1-negative T-ALL patients. Results: The median age of the 19 SIL-TAL1-positive T-ALL patients was 15 (7 to 41 years) , including 16 males (84.2%) . SIL-TAL1-positive T-ALL patients had younger age, higher WBC, and hemoglobin compared with SIL-TAL1-negative T-ALL patients. There was no discrepancy in gender distribution, PLT, chromosome abnormality distribution, immunophenotyping, and complete remission (CR) rate. The 3-year overall survival (OS) was 60.9% and 74.4%, respectively (HR=2.070, P=0.071) . The 3-year relapse-free survival (RFS) was 49.2% and 70.6%, respectively (HR=2.275, P=0.040) . The 3-year RFS rate of SIL-TAL1-positive T-ALL patients was considerably lower than SIL-TAL1-negative T-ALL patients. Conclusion: SIL-TAL1-positive T-ALL patients were connected to younger age, higher WBC, higher HGB, and poor outcome.

Abstract
Objective: To analyze the bronchoscopic manifestations and interventional treatment of pulmonary mucormycosis. Methods: Clinical data of patients with pulmonary mucormycosis undergoing bronchoscopy and interventional therapy in 4 tertiary general hospitals in China from May 2006 to May 2022 were retrospectively analyzed and the literature on the subject were reviewed. Results: The data of 10 patients with pathologically diagnosed pulmonary mucormycosis undergoing bronchoscopy and interventional therapy were collected, including 8 males and 2 females. The patients' age ranged from 21 to 72 (44±15) years. The underlying diseases included 6 cases of diabetes ketoacidosis, 3 cases of leukemia, 1 case after operation of lung cancer. Bronchoscopy showed that white viscous necrotic matters grew along the airway and blocked the airway in 9 cases, accompanied by airway bleeding in 3 cases, bloody secretion blocked the airway in 1 case, and bronchopulmonary cavity fistula in 2 cases. The biopsy histopathology of white necrotic matters showed that many mucor filaments were tangled together which were named mucormycelium. Among the 10 patients, 9 were treated with systemic drugs, including intravenous application of amphotericin B deoxycholate in 5 cases, intravenous application of amphotericin B liposome in 4 cases, oral posaconazole in 6 cases and intravenous injection in 1 case. Local drug therapy included aerosol inhalation of amphotericin B deoxycholate in 8 cases and local perfusion under bronchoscope in 5 cases. Bronchoscopic interventional therapy was used to remove mucormycelium in the bronchus, including cryotherapy in 8 cases, biopsy forceps in 7 cases, snare treatment in 2 cases and foreign body forceps in 2 cases. All 10 patients were clinical cured and with no death. Conclusions: Pulmonary mucormycosis is more common in immunocompromised hosts. Bronchoscopy often showed mucormycelium blocking the airway. Systemic and local drug therapy combined with bronchoscopic interventional therapy can achieve good clinical efficacy.

Abstract
Additive manufacturing (AM) is the key to creating a wide variety of 3D structures with unique and programmable functionalities. Direct ink writing is one of the widely used AM technologies with numerous printable materials. However, the extrude-based method is limited by low fabrication resolution, which is confined to printing macrostructures. Herein, a new AM strategy is reported, using a low-cost extrusion 3D printer, to create 3D microarchitectures at the macroscopic level through controlled desiccation of preprinted hydrogel scaffolds followed by infilling objective components. A printable hydrogel with a high-water content ensures maximum shrinkage (≈99.5% in volume) of the printed scaffolds to achieve high resolution. Stable covalent cross-linking and a suitable drying rate enable uniform shrinkage of the scaffolds to retain their original architectures. Particularly, this method can be adapted to produce liquid-metal-based 3D circuits and nanocomposite-based microrobots, indicating its capability to fabricate functional and complex 3D architectures with micron-level resolution from different material systems.

Abstract
Objective: To evaluate the endoscopic treatment efficacy of colorectal laterally spreading tumor (LST) and analyze the risk factors for delayed post-polypectomy bleeding (DPPB). Methods: Between January 2015 and December 2020, patients underwent colorectal endoscopic submucosal dissection (ESD) or hybrid ESD were recruited from the Second Affiliated Hospital of Zhejiang University. Complete resection rate, perforation rate, bleeding rate, operation time and lesion adhesion were compared between the ESD and hybrid ESD groups. Patients were divided into bleeding and non-bleeding groups based on the presence of DPPB. Multivariate logistic regression analysis was used to analyze the risk factors of DPPB. Results: A total of 665 patients with colorectal LST were enrolled, including 376 males and 289 females, with an average age of (57.4±0.4) years. There were 471 cases underwent ESD and 194 cases underwent hybridized ESD. There were no significant differences in gender, age, history of smoking and drinking, and prevalence of hypertension between the two groups (all P>0.05). Likewise, the rate of lesion adhesion (4.2% vs 7.7%, P=0.067), lesion complete resection (96.8% vs 93.8%, P=0.418), perforation (0.6% vs 1.0%, P=0.594), delayed bleeding (2.8% vs 2.1%, P=0.605) were not statistically significant between the two groups. Seventeen patients (2.6%) developed DPPB after endoscopic treatment. Multivariate logistic regression analysis showed that the lesion was in the rectum (OR=3.594, 95%CI: 1.237-10.443, P=0.019) and the diameter of the lesion>2 cm (OR=3.776, 95%CI: 1.411-10.106, P=0.008) were risk factors for DPPB. Conclusions: Both ESD and hybrid ESD are successful treatments for colorectal LST. Colorectal LST lesion site and lesion size>2 cm are risk factors of DPPB.

Abstract
Objective: To investigate the pathogen composition, initial anti-infectives and pathogen coverage, and trends over the last 5 years in children with septic shock in pediatric intensive care unit (PICU). Methods: The single-center retrospective study included 257 children with septic shock who were admitted to PICU of Beijing Children's Hospital, Capital Medical University from 2017 to 2021. The causitive pathogen composition, initial use of anti-infective drugs, pathogen coverage, and changes in recent years were analyzed. The children were divided into sufficient and insufficient coverage groups according to whether the pathogen were sufficiently covered by initial anti-infectives; community-and hospital-acquired groups; and with and without underlying disease groups. T test, rank-sum test and Chi-square test were used for comparison between the groups to investigate the differences in pathogen, treatment and prognosis. Results: A total of 257 septic shock children were included, with 162 males and 95 females, aged 36 (12, 117) months. The pathogen positive rate was 64.6% (166/257) and the in-hospital mortality was 27.6% (71/257). In the 208 pathogen-positive samples, bacteria was the most common (57.7%, 120/208) with G-negative bacteria predominating (55.8%, 67/120), followed by viruses (26.0%, 54/208). Nearly 99.2% (255/257) of the children were treated with antibacterial at the beginning, of whom 47.1% (121/257) were treated with carbapenems combined with vancomycin or linezolid. The proportion of 3 or more antibacterial combinations was higher in children with underlying diseases and hospital-acquired septic shock than in those without underlying disease or community-acquired septic shock (27.4% (49/179) vs. 14.1% (11/78), 29.4% (52/177) vs. 10.0% (8/80), χ2=5.35,11.56,all P<0.05). The proportion of initial combination of carbapenem and vancomycin or linezolid reduced from 52.5% (21/40) to 41.3% (19/46), and of adequate pathogen coverage increased from 40.0% (16/40) to 58.7% (27/46) in the last five years. Conclusions: The initial use of antibacterial drugs is common in children with septic shock in PICU, especially in those with hospital-acquired septic shock and underlying diseases. In recent years, antimicrobial combinations have decreased, but the pathogen coverage has improved, indicating that drug selection is more reasonable and accurate.

Abstract
Objective: To analyze the influencing factors of healthy life expectancy (HLE). Methods: Seven Chinese and English databases were used for the retrieval of related literatures published by May 7, 2022 to identify influencing factors of HLE, including diseases and injuries and their risk factors. Based on the ecological model of health determinants, this study classifies the risk factors of diseases and injuries into five levels: personal characteristics, individual behavior and lifestyle, social network, living and working conditions, and macroscopic socio-economic, cultural and environmental conditions. Contents of research area, HLE indicators, research population, influencing factors, data sources and results were extracted. The frequencies of reported documents of different HLE indicators and influencing factors of different dimensions were visualized by using evidence map, and the empirical studies of four authoritative English medical journals and Chinese core medical journals were further compared and described. Results: A total of 90 studies were selected, in which 26 were conducted in China (28.9%). Fifty-three studies are about diseases and injuries in the first dimension, and all of them have studied non-communicable diseases, accounting for the highest proportion (58.9%). There were 77 studies about the analysis on the determinants of health at five levels by an ecological model, all the studies reported multi-level results. Among them, 53 studies reported personal characteristics (58.9%), 47 studies reported individual behavior and lifestyle (52.2%), 10 studies reported social networks (11.1%), 35 studies reported living and working environment (38.9%), 8 studies reported social economy, culture status and environment condition (8.9%). The literatures about HLE published by 4 authoritative English medical journals and 21 Chinese core medical journals in recent three years were selected. Non-communicable diseases and personal characteristics were the top two most commonly studied factors of HLE, and 11 (52.3%) and 12 (57.1%) studies reported these two kinds of factors respectively. The most important factor contributing to the global disability-adjusted life years of non-communicable diseases was individual behavior and lifestyle, which was the most changeable factor. Conclusions: In recent three years, studies involving influencing factors of HLE were mainly non-communicable diseases and personal characteristics. In the future, individual behavior, lifestyle and working environment should be strengthened.

Abstract
BACKGROUND Left cardiac myxoma (CM) is the most common benign tumor of primary cardiac tumors, but because of its special position caused by pathological physiology change, caused by the complications of the heavier, the surface is often accompanied by blood clots, once fall out, it causes peripheral vascular embolization, such as acute lower limb artery embolization, harmfulness is large, high morbidity, and easy to occur repeatedly.
CASE SUMMARY A 67-year-old male patient suddenly appeared numbness and weakness of the left lower limb and could not walk without obvious incentive. The patient was finally diagnosed as left CM complicated with acute lower limb arterial embolism after completing cardiac ultrasound, computer tomography angiography, and histopathological analysis, such as hematoxylin-eosin stain staining, immunohistochemistry and special staining including alcian blue staining and periodic acid schiff staining. Arterial thrombosis was removed successfully by femoral artery thrombectomy, postoperative numbness and weakness of the patient's left lower limb disappeared, skin temperature became warm, and dorsal foot artery pulsation was accessible. The patient was readmitted to the hospital 8 mo after discharge for left atrial mass resection, and was diagnosed as CM by postoperative histopathological examination.
CONCLUSION Although CM is rare, it may be considered as the source of embolism in patients with acute limb ischemia. Repeated loss of thrombus on the tumor and its surface may lead to repeated embolism of peripheral vessels. Cardiac ultrasound is helpful for early diagnosis. Here, we use this case report to highlight left CM as an important cause of acute limb ischemia and to report our experience in the diagnosis and treatment of lower limb arterial embolism caused by CM detachment.

Abstract
Since April 2022, severe acute hepatitis of unknown origin in children has spread to 35 countries and regions around the world, and more than 1 010 cases have been reported. Since the severe acute hepatitis of unknown origin involves a wide range of areas and has a high rate, it is critical to identify the etiology and establish effective preventive, diagnostic and therapeutic measures as soon as possible. This study discusses the possible mechanisms and countermeasures of the severe acute hepatitis of unknown origin in children. It speculates that the occurrence of the recent severe acute hepatitis might be related to adenovirus, adeno-associated virus infection, and the COVID-19 epidemic, while the difference in HLA polymorphism among different races might be related to the fact that reported cases were more common in Europe and the United States. Based on the currently available evidence, it can be preliminarily judged that the risk of large-scale outbreak of severe acute hepatitis of unknown origin in children would be low in China, but the persistent awareness and vigilance of the etiology is still needed.

Abstract
Objective: To Summarize the safety, clinical outcome and technical evolution of laparoscopic gastric cancer surgery. Methods: A retrospective cohort study was carried out. Clinical data of 3012 patients who underwent laparoscopic radical gastrectomy for gastric cancer from January 2010 to March 2022 at Department of General Surgery, the First Affiliated Hospital of Nanjing Medical University were retrospectively collected and analyzed. Case inclusion criteria were gastric malignancies confirmed by pathology, without distant metastasis by examination before operation and exploration during operation, patients undergoing laparoscopic radical gastrectomy, intact function of important organs and with complete data. Exclusion criteria were patients who underwent emergency gastric cancer resection due to gastric bleeding, perforation or obstruction, etc., tumor found to invade adjacent organs such as pancreas or transverse colon during the operation, conversion to open surgery during the operation, those who had other malignant tumors (except thyroid cancer) within 5 years, and those had severe cardiopulmonary, liver, or kidney insufficiency before surgery. Outcomes included: (1) baseline information of patients; (2) trend of the quantity of laparoscopic radical gastrectomy year by year; (3) evolution of the mode of digestive tract reconstruction; (4) periopertive outcome short-term complication was defined as complication occurring within 30 days after operation and classified accordiny to the clavien-Dindo criteria; and (5) 5-year overall survival. SPSS software was used for statistical analysis. Continuous variables that obeyed the normal distribution were expressed in the form of Mean±SD. Days of hospital stay that did not follow a normal distribution were expressed as median (Q1,Q3), and the Mann-Whiney U test was used for comparison. Discrete variables were expressed as cases (%), and chi-square test or rank sum test was used for comparison between groups. Linear regression analysis was used to analyze the relationship between the amount of surgery and the year of surgery. Kaplan-Meier method and log-rank test were used for survival analysis. Two-tailed P<0.05 was considered as statistically significant. Results: Among the 3012 cases, 2114 were male and 898 were female. The patients' average age at surgery was (61.1±10.7) years old. According to the number of cumulative cases, the patients were divided into three groups: early, intermediate and late, with 1004 patients in each group. The early group consisted of patients undergoing operation from January 2010 to October 2018, the intermediate group consisted of patients undergoing operation from October 2018 to January 2021, and the late group consisted of patients undergoing operation from January 2021 to March 2022. (1) General information: There were 691 (68.8%), 699 (69.6%) and 724 (72.1%) male patients in early, intermediate and late groups respectively; the average age increased from 56.6 years in 2010 to 62.8 years in March 2022. As for the tumor stage T1, T2, T3, T4, there were 49.0%, 14.4%, 23.9% and 12.6% in the early group; 47.5%, 12.9%, 26.9% and 12.6% in the intermediate group; 39.7%, 14.6%, 30.0%, and 15.6% in the late group, respectively. Patients with N0, N1, N2, N3a, N3b stage were 56.8%, 13.7%, 13.4%, 11.0%, and 5.0% in the early group; 55.7%, 12.9%, 12.8%, 11.6%, and 6.9% in the intermediate group; 51.0%, 16.1%, 12.8%, 12.5%, and 7.5% in the late group, respectively. (2) Year-by-year change in the number of gastric cancer operations: From 19 cases per year in 2010 to 786 per year in 2021, the annual number of gastric cancer operations was proportional to the year of operation (y=47.505x, R2=0.67). The proportion of patients with stage I disease showed a fluctuating downward trend over time, while the proportion of patients with stage III disease increased slightly, accounting for 34% until March 2022. (3) Evolution of digestive tract reconstruction methods: Except in 2010, the digestive tract reconstruction method of distal gastrectomy focused on Billroth-II+Braun anastomosis among patients undergoing laparoscopic gastric cancer surgery in other years, whose proportion had gradually increased from less than 20% in 2016 to about 70% after 2021; the gastrointestinal reconstruction methods after total gastrectomy had gradually increased in π anastomosis and overlap anastomosis since 2016, of which π anastomosis reached about 65% in 2019, and overlap anastomosis reached almost 30% in 2020; the anastomosis methods after proximal gastrectomy had been mainly double-channel anastomosis (54%) and esophagogastric anastomosis (30%) since 2016, and double-channel anastomosis accounted for up to 70% in 2019. (4) Operation time: The operation time of early, intermediate and late group was (193.3±49.8) min, (186.9±44.3) min and (206.7±51.4) min respectively. Intermediate group was significantly shorter than early group (t=3.005, P=0.003), while late group was significantly longer than early group (t=5.875, P<0.001) and intermediate group (t=9.180, P<0.001). (5) Postoperative hospital stay: The median length of hospital stay for gastric cancer patients in early, intermediate and late groups was 9 (8, 11) d, 8 (7, 10) d, and 8 (7.5, 10) d respectively. The postoperative hospital stay of intermediate group and late group was significantly shorter than that of early group (Z=-12.467, Z=-5.981, both P<0.001), but there was no significant difference between intermediate group and late group (Z=0.415,P=0.678). (6) Postoperative complication: The morbidity of short-term complication in early, intermediate and late group was 20.4% (205/1004), 16.2% (163/1004), and 16.2% (162/1004) respectively, and above morbidity of intermediate group and late group was significantly lower than that of early group (χ2=5.869, P=0.015; χ2=6.165, P=0.013), while there was no significant difference between intermediate group and late group (χ2=0.004,P=0.952). The morbidity of short-term complication of grade IIIor higher was 8.0% (80/1004), 7.6% (76/1004), and 4.9% (49/1004) in early, intermediate and late group respectively, and above morbidity of late group was significantly lower than that of early and intermediate group (χ2=7.965, P=0.005; χ2=6.219,P=0.013), while there was no significant difference between intermediate group and early group (χ2=0.111,P=0.739). (7) Survival analysis: The follow-up deadline for survival data was December 31, 2021, and the median follow-up time was 29.5 months. The overall 5-year survival rate of all the patients was 74.7%. The 5-year survival rates of stage I, II and III patients were 92.0%, 77.2%, and 40.3% respectively and 5-year survival rates of patients with stage IA, IB, IIA, IIB, IIIA, IIIB and IIIC were 93.2%, 87.8%, 81.1%, 72.7%, 46.2%, 37.1%, and 34.0% respectively. Conclusions: The number of laparoscopic gastric cancer operation in our center is increasing year by year. With the maturity of laparoscopic technology, the morbidity of complication in laparoscopic gastric cancer surgery is decreasing.

Abstract
OBJECTIVE To characterize the species of invasive Pomacea snails that were discovered for the first time in Shandong Province. METHODS Pomacea snails samples were collected in the field of Jining City, Shandong Province on October 2021 for morphological identification. Pomacea snails were randomly sampled and genomic DNA was extracted from foot muscle tissues of Pomacea snails for multiplex PCR amplification. The PCR amplification product was sequenced. Then, the sequence was aligned and a phylogenetic tree was created using the software MegAlign 7.1.0. In addition, Angiostongylus cantonensis infection was detected in Pomacea snails with the lung microscopy. RESULTS A total of 104 living Pomacea snails were collected, and all were characterized as Pomacea spp. based on morphological features. Of 12 randomly selected adult Pomacea snails, multiplex PCR assay and sequencing identified eleven snails as P. canaliculata and one as P. maculata. No A. cantonensis infection was detected in 104 Pomacea snails. CONCLUSIONS This is the first report of invasive Pomacea snails in Shandong Province, where P. canaliculata and P. maculata are found.

Abstract
Phenome-wide association study (PheWAS) is a reverse genetic analysis method to identify the potential phenotypes associated with genetic variations. With the increasing availability of biomedical databases and electronic medical records (EMR), PheWAS has gradually become an effective tool to unveil the relationships between exposure and a broad range of health phenotypes. The unique advantage of this method is that it can simultaneously explore the associations of a specific exposure with a variety of disease outcomes, thus helping to reveal multiple causal relationships and the shared pathogenic mechanisms among diseases. However, PheWAS has limitations, including selecting instrumental variables and the heavy burden of various corrections. In addition, how to interpret the biological mechanisms underlying significant findings is another crucial issue of PheWAS. This review will focus on the methodology and application of PheWAS to provide meaningful suggestions and insights for future studies.

Abstract
Objective: To explore the effects of mothers' exposure to polycyclic aromatic hydrocarbons during pregnancy on their children's neurobehavioral development. Methods: In November 2009 to April 2010, a total of 221 pairs of mother-newborn pairs were recruited from two cooperative hospitals in Taiyuan, and their children were followed up at age two. High performance liquid chromatography was used to determine the level of BPDE-DNA in cord blood leukocytes. The Neonatal behavioral neurological assessment (NBNA) was used to assess the neurodevelopment of newborns, and the Gesell Development Scale was used to measure neurodevelopmental indexes of 2-year-old children. NBNA includes behavior, active and passive tone, primitive reflexes and general assessment, with a total score of 40 points. The Gesell Developmental Schedules consisted of four sub-scales: motor development, adaptive behavior development, language development and personal-social behavior development. We used mean and standard deviation to describe continuous variables with normal distribution, median (interquartile range) to describe continuous variables with skewed distribution, and frequency and proportion to describe categorical variables. Restricted cubic spline models were applied to assess the dose-response relationships between maternal prenatal polycyclic aromatic hydrocarbons exposure and children's neurobehavioral development at two years old. Generalized linear models were applied to evaluate the effect of exposure to maternal prenatal polycyclic aromatic hydrocarbons exposure on children's neurobehavioral development at 0 and two years old. Results: The NBNA score was 38.0±0.8, and the scores of 2-year-old children's motor, adaptive, language and personal-social were 111.6±15.0, 110.5±14.6, 108.8±17.2 and 111.7±14.5, respectively. After adjusting for confounding factors, there is no dose-response association between the cord blood BPDE of pregnant women and neonatal NBNA scores, but there were dose-response associations between BPDE and scores of 2-year-old children's motor, adaptive, language and personal-social. A unit increase in cord blood ln (BPDE-DNA), the score of motor, adaptive, language and personal-social of 2-year-old children decreased on average by 4.54、6.29、8.41 and 7.02 points. Conclusion: Maternal exposure to polycyclic aromatic hydrocarbons during pregnancy is associated with decreased children's neurobehavioral development at two years old.

Abstract
Laparoscopic techniques are more and more poplular in proximal gastrectomy. The traditional esophagogastric anastomosis may lead to severe reflux esophagitis after surgery, affecting patient's quality of life. In recent years, multiple methods of digestive tract reconstruction after laparoscopic proximal gastrectomy capable of resisting reflux have been applied to the clinic. Combining the results of the latest clinical studies and our clinical experience, we elaborate the views on digestive tract reconstruction after laparoscopic proximal gastrectomy. Esophagogastric anastomosis (posterior esophagogastric anastomosis, anterior esophagogastric anastomosis, gastric tube reconstruction, lateral esophagogastric anastomosis, Kamikawa anastomosis and modified Kamikawa anastomosis, etc.) and esophagojejunal anastomosis (interposition jejunum, interposition jejunum with pouch, and double-channel anastomosis, etc.) are mainly discussed. Of course, the anti-reflux mechanisms of different surgical procedures are not the same, the anti-reflux effects are variable, and the surgical difficulties under laparoscopy are also different. Therefore, how to choose a rational reconstruction method after proximal gastrectomy needs to be comprehensively considered based on patient's own situation and technical level of the surgeons.

Abstract
Objective: To understand the virulence gene and drug resistance profile of Shigella sonnei outbreak in Huainan city, and conduct pathogenic traceability analysis. Methods: Water samples and feces related to an infectious diarrhea outbreak in Huainan city in August 2020 were collected for multiple pathogen detection. Virulence gene, drug sensitivity, pulse-field gel electrophoresis and whole genome sequencing of Shigella isolates were analyzed respectively. Results: 38 strains of Shigella sonnei were detected in 56 samples of mucilage feces with a positive rate 67.86%, and all serotypes were Shigella sonnei Phase I. Three strains of Shigella sonnei were detected by fluorescence PCR in the Gram-negative (GN) bacterial enrichment solution of terminal water and well water. Virulence genes were ipaH positive (38), ipaH/ial (31) and ipaH/ial/sen positive (1), respectively. The drug resistance spectrum showed that 9 of 14 antibiotics were 100% resistant, and only imipenem, chloramphenicol, ceftazidime and ciprofloxacin were effective drugs. XbaⅠ restriction enzyme map type of 36 isolates was completely consistent, and the ST type analysis of 3 strains was ST152. Whole genome sequencing and analysis verified that the outbreak was caused by a single clonal group of strains, and revealed that the isolates of the outbreak were clustered into a large cluster with 3 Chinese strains and 1 Korean strain in the database, far away from the strains of other countries. Conclusion: The outbreak is caused by a single clone of Shigella sonnei, which are low virulence strains and have multiple drug resistance.

Abstract
In insects, metamorphosis is controlled by juvenile hormone (JH) and 20-hydroxyecdysone (20E). Krüppel homolog 1 (Kr-h1), a key JH-early inducible gene, is responsible for the suppression of metamorphosis and the regulation of the Broad-Complex (Br-C) gene, which is induced by 20E and functions as a “pupal specifier”. In this study, we identified and characterized the expression patterns and tissue distribution of DaKr-h1 and DaBr-C at various developmental stages of Dendroctonus armandi. The expression of the two genes was induced by JH analog (JHA) methoprene and 20E, and their functions were investigated by RNA interference. DaKr-h1 and DaBr-C were predominantly expressed in the heads of larvae and were significantly downregulated during the molting stage. In contrast, the DaKr-h1 transcript level was highest in the adult anterior midgut. DaBr-C was mainly expressed in female adults, with the highest transcript levels in the ovaries. In the larval and pupal stages, both JHA and 20E significantly induced DaKr-h1, but only 20E significantly induced DaBr-C, indicating the importance of hormones in metamorphosis. DaKr-h1 knockdown in larvae upregulated DaBr-C expression, resulting in precocious metamorphosis from larvae to pupae and the formation of miniature pupae. DaKr-h1 knockdown in pupae suppressed DaBr-C expression, increased emergence, caused abnormal morphology, and caused the formation of small-winged adults. These results suggest that DaKr-h1 is required for the metamorphosis of D. armandi. Our findings provide insight into the roles of DaKr-h1 and DaBr-C in JH-induced transcriptional repression and highlight DaKr-h1 as a potential target for metamorphosis suppression in D. armandi.

Abstract
Objective: To analyze the clinical characteristics and treatment of critically ill children with acute chlorine poisoning and explore the risk factors and effective strategies. Methods: This retrospective study collected the clinical data, including general state, clinical characteristics, treatment and follow-up(till 1 year and 6 months after discharge), of 6 critically ill children who were hospitalized in the Pediatric Intensive Care Unit of Beijing Children's Hospital due to acute chlorine poisoning in August 2019. Results: There were 6 children characterized by severe dyspnea in this accident, among whom 4 were boys and two girls, aged 4-12 years. When the accident occurred, they were within 5 m of the chlorine source. These patients underwent tracheal intubation and mechanical ventilation in 3.5-7.0 h after poisoning. The child who was the closest to the chlorine source (1.5 m) and took the longest time (5 min) to evacuate was the most severe one. He suffered hypoxia which could not be corrected by conventional mechanical ventilation and severe shock, then had veno-arterial extracorporeal membrane oxygenation(ECMO) treatment started 10 h after the accident. All the 6 children in this study survived. Following-up found no growth and developmental abnormality. The pulmonary function tests were normal except for one case with increased small airway resistance due to previous suspected asthma, and the lung CT, electhoencephalogram, and brain magnetic resonance imaging were all normal. Conclusions: Severe chlorine poisoning is mainly characterized by respiratory failure. Mechanical ventilation is often required within a few hours after poisoning. When conventional mechanical ventilation is ineffective, ECMO could save live. Timely treatment could improve prognosis.

Abstract
Objective: To analyze mortality and its trend of chronic respiratory diseases (CRD) in China from 1990 to 2019. Methods: Based on the provincial results of China from the 2019 Global Burden of Disease (GBD) study, the average annual percent change (AAPC) of standardized mortality rates of different CRDs were analyzed by using Joinpoint 4.8.0.1, and the age-standardized mortality rate of CRD was calculated by using the GBD 2019 world standard population. Based on the comparative risk assessment theory of GBD, the attributable deaths due to 12 CRD risk factors were estimated, including smoking, indoor air pollution, occupational gas exposure, particulates and smog exposure, environmental particulate pollution, low temperature, passive smoking, ozone pollution, occupational exposure to silica, occupational asthma, high body mass index, high temperature and occupational exposure to asbestos. Results: From 1990 to 2019, the number of deaths and standardized mortality of chronic obstructive pulmonary disease (COPD) showed a downward trend (P<0.001). The number of COPD deaths decreased from 1 244 000 (912 000 - 1 395 000) in 1990 to 1 037 000 (889 000 - 1 266 000) in 2019. AAPC=-0.9% (95%CI: -1.5% - -0.3%), P<0.001; The standardized mortality rate decreased from 217.9/100 000 (163.3/100 000 - 242.0/100 000) in 1990 to 65.2/100 000 (55.5/100 000 - 80.1/100 000) in 2019. AAPC= -4.2% (95%CI:-5.2% - -3.2%), P<0.001. The number of deaths from asthma decreased from 40 000 (30 000 - 58 000) in 1990 to 25 000 (20 000 - 31 000) in 2019. AAPC=-2.0% (95%CI: -2.6% - -1.4%), P<0.001; The standardized mortality rate of asthma decreased from 6.4/100 000 (4.7/100 000 - 9.5/100 000) in 1990 to 1.5/100 000 (1.2/100 000 - 1.9/100 000) in 2019. AAPC=-5.1% (95%CI: -5.8% - -4.4%), P<0.001. The number of pneumoconiosis deaths decreased from 11 000 (8 000 - 14 000) in 1990 to 10 000 (8 000 - 14 000) in 2019, AAPC=-0.2%(95%CI:-0.4% - 0.1%), P=0.200; The standardized mortality rate of pneumoconiosis decreased from 1.4/100 000 (1.0/100 000 - 1.7/100 000) in 1990 to 0.5/100 000 (0.4/100 000 - 0.7/100 000) in 2019. AAPC=-3.1% (95%CI: -3.4% - -2.8%), P<0.001. The number of deaths from pulmonary interstitial diseases and pulmonary sarcoidosis increased from 3 000 (3 000 - 6 000) in 1990 to 8 000 (6 000 - 10 000) in 2019, AAPC=3.5% (95%CI: 2.7% - 4.2%), P<0.001; The corresponding standardized mortality rate changed little from 1990 to 2019, and AAPC was not statistically significant.The age-standardized mortality rates of different CRDs were higher in men than those in women. In 1990 and 2019, the mortality rates of COPD, asthma, pneumoconiosis and interstitial pulmonary disease and pulmonary sarcoidosis increased with age. In 2019, the population attributable fractions (PAFs) for smoking, environmental particulate pollution, occupational gas exposure, particulate and smog exposure, low temperature exposure and passive smoking were 71.1% (68.0% - 74.3%), 24.7% (20.1% - 30.0%), 19.3% (13.0% - 25.4%), 15.7% (13.6% - 18.3%) and 8.8% (4.5% - 13.1%) respectively in men, and the PAFs for environmental particulate pollution, smoking, low temperature exposure, occupational gas exposure, particulate and smog exposure, and passive smoking were 24.1% (19.6% - 29.3%), 21.9% (18.7% - 25.2%), 16.4% (14.0% - 19.2%), 15.6% (10.2% - 21.1%) and 14.7% (7.9% - 21.3%) respectively in women. Conclusions: During 1990-2019, the overall death level of CRD decreased significantly in China, but it is still at high level in the world. Active prevention and control measures should be taken to reduce the death level caused by CRD.

Abstract
The first-line nucleos(t)ide analogs (NAs) based antiviral drugs can effectively inhibit HBV replication and slow down the progression of chronic hepatitis B. However, about 20% of patients receiving standard NAs antiviral therapy will still develop low-level viremia (LLV). Therefore, understanding the occurrence mechanism of LLV will help to optimize antiviral treatment regimens and improve the prognosis of patients with chronic hepatitis B. This article systematically summarizes the possible mechanisms of LLV occurrence, and the important factor of NAs failure. Taking into account the unique limitations of NAs competitive inhibition of virus replication, weakening host's immune response is not enough to directly eliminate infected hepatocytes. This makes it difficult to achieve a complete virological response in some patients with the active compensatory proliferation of residual infected hepatocytes and the accompanying effective removal or dilution of covalent, closed, circular DNA (cccDNA) pools. Therefore, it is speculated that activating host immunity can eliminate infected liver cells and may be more conducive to address LLV.

Abstract
We measured the ground-state hyperfine splitting of trapped 113Cd+ ions to be 15199862855.02799(27) Hz with a fractional uncertainty of 1.8×10-14. The ions were trapped and laser-cooled in a linear quadrupole Paul trap. The fractional frequency stability was measured to be 4.2×10-13/τ, obtained from Ramsey fringes of high signal-to-noise ratios and taken over a measurement time of nearly 5 h, which is close to the short-term stability limit estimated from the Dick effect. Our result is consistent with previously reported values, but the measurement precision is four times better than the best result obtained to date.

Abstract
The aim of this study was to assess the effects of orlistat or metformin treatment on lipid and glucose metabolism, and gonadal function in obese/overweight women with polycystic ovary syndrome (PCOS). A total of 39 patients diagnosed with PCOS were randomly (digital table method) divided into orlistat treatment group (20 cases) and metformin treatment group (19 cases). Compared with those before, treatment with either orlistat or metformin significantly reduced body weight, body mass index (BMI), hip circumferences, and serum insulin levels of the PCOS patients both at the end of 3 months and 6 months (P<0.05). No significant differences could be viewed between orlistat and metformin treated subjects. Moreover, orlistat treatment significantly lowered the levels of low-density lipoprotein cholesterol, total cholesterol, fasting blood glucose, and homeostasis model assessment-insulin resistance (HOMA-IR) (P<0.05), while there were no significant changes in above parameters with metformin treatment. The improvement of menstrual cycle was observed after 6-month treatment in both groups (P<0.05). However, changes in polycystic ovarian morphology by ultrasound were only observed in orlistat treated group. In conclusion, orlistat is comparable with metformin in weight loss and improvement of insulin resistance and menstrual cycle, and is superior to metformin in improvement of lipid metabolism in overweight/obese PCOS patients.

Abstract
Tyrosinase (polyphenol oxidase) is the key enzyme of enzymatic browning in fruits and vegetables. In this research, the impact of ascorbic acid on tyrosinase and its anti-browning effect on fresh-cut Fuji apple were investigated. Ascorbic acid had a dual effect on tyrosinase with a half inhibitory concentration (IC50 ) of 13.40 ± 0.05 µM. Fluorescence assay demonstrated that ascorbic acid interacted with tyrosinase in a dynamic contaction caused by Förster's resonance energy transfer (FRET) and induced a conformational change of the enzyme. Thermodynamic analysis, copper interaction, and molecular docking further confirmed that ascorbic acid could chelate the copper ions located in active center and interact with amino acid residues of tyrosinase via hydrophobic interaction. In addition, ascorbic acid prevented the browning of fresh-cut apples by increasing APX activity and inhibiting PPO and POD activities which reduce the oxidation of total phenolics and flavonoids. PRACTICAL APPLICATIONS: The present study demonstrated that ascorbic acid had a strong inhibitory activity against tyrosinase (IC50 = 13.40 ± 0.05 µM) and anti-browning activity against fresh-cut Fuji apple. It could delay the browning degree of apple juice, increase APX activity, inhibit PPO and POD activities, and reduce the oxidation of total phenolics and flavonoids. These findings provided a basis for the feasible application of ascorbic acid on the preservation of fruits.

Abstract
To compare changes in platelet related parameters in obese patients before and after sleeve gastrectomy (SG), we retrospectively analyzed the clinical data of 31 obese patients who underwent SG in Peking Union Medical College Hospital from December 2012 to September 2020. Results showed that compared with those before surgery, platelet count (PLT) decreased significantly at 2-12 weeks of follow-up (P=0.009), while platelet distribution width (PDW), mean platelet volume (MPV), and large platelet ratio (P-LCR) increased significantly at the same periods of follow-up after operation (P<0.001). However, the levels of PDW, MPV, and P-LCR began to decrease at 16-55 weeks when compared with those at 2-12 weeks of follow-up (P<0.01). PLT was positively correlated with white blood cells and neutrophils at 2-12 weeks of follow-up and positively correlated with high sensitivity C-reactive protein at 16-55 weeks of follow-up after operation (P<0.05).

Abstract
IMPORTANCE Few studies have examined the clinicopathological characteristics and prognoses of patients with hepatoid adenocarcinoma of the stomach (HAS). OBJECTIVE To explore the clinicopathological characteristics and prognoses of patients with HAS and develop a nomogram to predict overall survival (OS). DESIGN, SETTING, AND PARTICIPANTS This prognostic study involved a retrospective analysis of data from 315 patients who received a diagnosis of primary HAS between April 1, 2004, and December 31, 2019, at 14 centers in China. MAIN OUTCOMES AND MEASURES OS and prognostic factors. Patients were randomly assigned to a derivation cohort (n = 220) and a validation cohort (n = 95). A nomogram was developed based on independent prognostic factors identified through a multivariable Cox mixed-effects model. RESULTS Among 315 patients with HAS (mean [SD] age, 61.9 [10.2] years; 240 men [76.2%]), 137 patients had simple HAS (defined as the presence of histologically contained hepatoid differentiation areas only), and 178 patients had mixed HAS (defined as the presence of hepatoid differentiation areas plus common adenocarcinoma areas). Patients with simple HAS had a higher median preoperative α-fetoprotein level than those with mixed HAS (195.9 ng/mL vs 48.9 ng/mL, respectively; P < .001) and a higher rate of preoperative liver metastasis (23 of 137 patients [16.8%] vs 11 of 178 patients [6.2%]; P = .003). The 3-year OS rates of patients with simple vs mixed HAS were comparable (56.0% vs 60.0%; log-rank P = .98). A multivariable Cox analysis of the derivation cohort found that the presence of perineural invasion (hazard ratio [HR], 2.13; 95% CI, 1.27-3.55; P = .009), preoperative carcinoembryonic antigen levels of 5 ng/mL or greater (HR, 1.72; 95% CI, 1.08-2.74; P = .03), and pathological node category 3b (HR, 3.72; 95% CI, 1.34-10.32; P = .01) were independent risk factors for worse OS. Based on these factors, a nomogram to predict postoperative OS was developed. The concordance indices of the nomogram (derivation cohort: 0.72 [95% CI, 0.66-0.78]; validation cohort: 0.72 [95% CI, 0.63-0.81]; whole cohort: 0.71 [95% CI, 0.66-0.76]) were higher than those derived using the American Joint Committee on Cancer's AJCC Cancer Staging Manual (8th edition) pathological tumor-node-metastasis (pTNM) staging system (derivation cohort: 0.63 [95% CI, 0.57-0.69]; validation cohort: 0.65 [95% CI, 0.56-0.75]; whole cohort: 0.64 [95% CI, 0.59-0.69]) and those derived using a clinical model that included pTNM stage and receipt of adjuvant chemotherapy (derivation cohort: 0.64 [95% CI, 0.58-0.69]; validation cohort: 0.65 [95% CI, 0.56-0.75]; whole cohort: 0.64 [95% CI, 0.59-0.69]). Based on the nomogram cutoff of 10 points, the whole cohort was divided into high-risk and low-risk groups. The 3-year OS rate of patients in the high-risk group was significantly lower than that of patients in the low-risk group (29.7% vs 75.9%, respectively; log-rank P < .001), and the 3-year prognosis of high-risk and low-risk groups could be further distinguished into pTNM stage I to II (33.3% vs 80.2%; exact log-rank P = .15), stage III (34.3% vs 71.3%; log-rank P < .001), and stage IV (15.5% vs 70.3%; log-rank P = .009). CONCLUSIONS AND RELEVANCE This study found that perineural invasion, preoperative carcinoembryonic antigen levels of 5 ng/mL or greater, and pathological node category 3b were independent risk factors associated with worse OS. An individualized nomogram was developed to predict OS among patients with HAS. This nomogram had good prognostic value and may be useful as a supplement to the current American Joint Committee on Cancer TNM staging system.

Abstract
OBJECTIVE To investigate the prevalence and changing trend of Enterobius vermicularis infections among children in Shandong Province, so as to provide the scientific evidence for the adjustment and development of the enterobiasis control strategy. METHODS Soil-borne nematodiasis surveillance sites were assigned in 51 counties (districts, cities) in Shandong Province from 2016 to 2020, and the E. vermicularis infections were detected using a modified Kato-Katz technique and the cellophane tape method among children at ages of 3 to 9 years living in these surveillance sites. The epidemiological profiles of E. vermicularis-infected children were descriptively analyzed. RESULTS A total of 5 060 children at ages of 3 to 9 years were detected in 51 soil-borne nematodiasis surveillance sites in Shandong Province from 2016 to 2020, and the overall prevalence of E. vermicularis infections was 2.23%. The annual prevalence of E. vermicularis infections was 3.99% (26/651), 1.70% (14/824), 0.96% (8/837), 2.90% (45/1 552) and 1.67% (20/1 196) from 2016 to 2020, respectively, with a significant difference detected among years (χ2 = 21.455, P < 0.01). The prevalence of E. vermicularis infections was 1.25% (15/1 198), 1.85% (14/755), 3.18% (84/2 640) and 0 (0/467) among children from central, eastern, southern and northern Shandong Province (χ2 = 27.326, P < 0.01). In addition, there was no significant difference in the prevalence of E. vermicularis infections between male (1.98%, 56/2 831) and female children (2.56%, 57/2 229) (χ2 = 1.916, P > 0.05); however, there was age-specific prevalence of E. vermicularis infections among children (χ2 = 16.448, P < 0.05), with the greatest prevalence detected among children at ages of 6 years (3.18%, 25/786), and the lowest prevalence seen among children at ages of 3 years (0.75%, 6/800). CONCLUSIONS The prevalence of E. vermicularis infections remained at a medium level among children at ages of 3 to 9 years in Shandong Province from 2016 to 2020, with region-specific prevalence found across the province. An integrated strategy is required for enterobiasis control.

Abstract
Objective: To understand the distribution patterns of the place of death (PoD) among individuals with cardiovascular disease (CVD) in the provinces of China in 2018. Relationships between CVD deaths in healthcare/medical institutions and individual demographics, social-economic status (SES), the underlying cause of death, and local cultural factors were also explored. Methods: Using data from the National Cause-of-death Reporting System, we examined potential, influential factors of CVD deaths in healthcare/medical institutions through multilevel logistic regression. Results: In 2018, there were 853 832 CVD deaths in disease surveillance points in the country, with 661 625 (77.49%) home deaths and 156 441 (18.32%) occurring in healthcare and medical institutions. Factors including sex, age, nationality, marital status, education level, occupation, the underlying cause of death, criterion for diagnosis, and urban/rural residency, were significantly influential on CVD deaths in healthcare/medical institutions. Meanwhile, spatial variations were shown at factors the subnational level, with 45.39% related to factors at the individual level. Conclusion: Home was the dominant place for CVD deaths in the country, with substantial spatial variations in PoD between provinces. The probability of dying in healthcare/medical settings was comparatively higher among CVD patients with superior socioeconomic status and who lived in urban areas. Adequate information should be collected and included in further studies on exploring influential factors of PoD. Since both social factors, individual preferences, and acute and chronic CVD deaths are critical, it is necessary to enhance treatment capacity. A booming approach incorporating home/hospice care with on-site medical services might also improve the quality of end-of-life care among CVD patients in China.

Abstract
Objective: To understand the geographical variations and temporal trends of all-cause mortality rate and life expectancy in China at national and subnational levels during 2005-2018. Methods: Using data from National Cause-of-death Reporting System, China National Maternal and Child Health Surveillance System, Under-reporting Surveys, and related social determinants covariates, we estimated all-cause mortality rate and life expectancy at national and subnational levels in China during 2005-2018. We depicted the geographical variations and temporal trends between provinces on mortality rate and life expectancy. We then decomposed changes in national and subnational deaths into three explanatory components: change due to age-specific mortality rate, change due to the population structure by age, and change due to growth of the total population. Results: In 2018, it was estimated that there were 10 482 297 total deaths (95%CI: 9 723 233-11 466 875 deaths) in China, with 6 113 926 men (95%CI: 5 773 158-6 572 407 men) and 4 368 241 women (95%CI: 3 950 075-4 894 468 women). The all-cause mortality rate was 755.54 per 100 000 (95%CI: 701.49 per 100 000-825.78 per 100 000), with 861.78 per 100 000 (95%CI: 813.75 per 100 000-926.40 per 100 000) in men and 642.73 per 100 000 (95%CI: 581.20 per 100 000-720.15 per 100 000) in women, while age-standardized all-cause mortality rate was 652.27 per 100 000 (95%CI: 599.22 per 100 000-721.71 per 100 000), with 806.38 per 100 000 (95%CI: 755.10 per 100 000-874.31 per 100 000) in men and 503.37 per 100 000 (95%CI: 450.50 per 100 000-572.01 per 100 000) in women. In 2018, it was estimated that the life expectancy in the whole country was 77.15 years old (95%CI: 75.92-78.11 years old), with 74.81 (95%CI: 73.57-75.76) in men and 79.87 (95%CI: 78.61-80.91) in women. Developed areas as Shanghai, Beijing, Jiangsu, and Zhejiang owned comparatively higher life expectancy, while undeveloped areas like Tibet, Guizhou, Xinjiang, and Qinghai showed lower levels. During 2005-2018, there was a 29.87% increase in total deaths at the national level, with 27.74% in men and 31.29% in women. Changes due to age-specific mortality rate, the population structure by age, and the growth of the total population constituted -35.74%, 7.34%, and 58.28% of the total increase, respectively. Conclusions: From 2005 to 2018, the all-cause mortality rate increased while the age-standardized mortality rate decreased substantially among Chinese residents. Change due to population structure by age was the dominant driver. An upward trend of life expectancy was observed in all provinces, with marked differences between the provinces.

Abstract
Objective: To explore the potential influences and applicability of different spatial weight matrices used in analyzing spatial autocorrelation of cardiovascular disease (CVD) mortality in China. Methods: Using data from the National Cause-of-death Reporting System, we used adjacency-based Rook and Queen contiguity and distance-based K nearest neighbors/distance threshold. We then conducted global and local spatial autocorrelation analysis of CVD mortality at the county level in China, 2018. Results: All four categories and 26 types of spatial weight matrices had detected significant global and local spatial autocorrelation of CVD mortality in China. Global Moran's I statistics reached its peak when using first-order Rook (0.406), first-order Queen (0.406), K nearest neighbors including five spatial units (0.409), and distance threshold with 100 kilometers (0.358). Meanwhile, apparent local spatial autocorrelation was found in CVD mortality. Substantial disparities were observed when detecting "High-High clusters", "Low-Low clusters", "High-Low clusters" and "Low-High clusters" of CVD mortality spatial distribution by using different weight matrices. Conclusions: Using different spatial weight matrices in analyzing the spatial autocorrelation of CVD mortality, we could understand the spatial distribution characteristics of CVD mortality in-depth at the county level in China. In this way, adequate supports could also be provided on CVD premature death control and rational medical resource allocation regionally.
