Objective To analyze the burden and epidemic trends of gastric cancer in China from 1990 to 2021, and to provide a scientific basis for the formulation of effective prevention and control strategies. Methods　Data from the 2021 Global Burden of Disease (GBD) database were used to extract the number of the incidence, prevalence, and death cases, as well as the disability-adjusted life years (DALY) for gastric cancer in China from 1990 to 2021. The corresponding crude rates and age-standardized rates were calculated. The Joinpoint regression model was employed to analyze the trends in the burden of gastric cancer, and a comprehensive examination was conducted from multiple dimensions including age, gender, and time. Results From 1990 to 2021, the age-standardized incidence rate (ASIR) of gastric cancer in China decreased from 48.03 per 100,000 to 29.05 per 100,000, the age-standardized prevalence rate (ASPR) decreased from 67.17 per 100,000 to 57.23 per 100,000, the age-standardized mortality rate (ASMR) decreased from 46.05 per 100,000 to 21.51 per 100,000, and the age-standardized DALY rate (ASDR) decreased from 1181.61 per 100,000 to 501.26 per 100,000. The AAPCs of ASIR, ASPR, ASMR, and ASDR were -1.61%, -0.50%, -2.44%, and -2.75%, respectively. The incidence, prevalence, mortality and DALY rates showed a trend of increasing first and then decreasing with age. Although females had higher incidence, prevalence, mortality, and DALY numbers in the older age groups, males exhibited higher crude rates across all age groups. Conclusion　The overall disease burden of gastric cancer in China showed a downward trend from 1990 to 2021, and men and middle-aged and elderly people are the key populations for prevention and control efforts.

The spectrum of biopsy-confirmed kidney disease varies with regions and periods. We describe the distribution of pathological types and epidemiological characteristics of kidney diseases in Northwest China due to regional differences in geographical environment, social economy, and dietary habits. Methods: Kidney biopsy cases from 2005 to 2020 in Xijing Hospital were retrospectively analyzed. Pathological characteristics of patients in different periods were analyzed using the t test or chi-square test. Joinpoint regression was used to analyze trends in pathological types and disease spectrum. Results: A total of 10,528 eligible patients were included. Primary glomerular disease (PGD) accounted for the majority of the cases and exhibited an obvious downward trend, whereas secondary glomerular disease (SGD) showed an obvious upward trend. Among PGD, immunoglobulin A nephropathy (IgAN) remained the most common pathological type, and the detection rate of membranous nephropathy (MN) was significantly increased. Among SGD, Henoch-Schönlein purpura nephritis (HSPN) was the most common pathological type and may present a significant characteristic of Northwest China. Diabetic nephropathy (DN) exhibited the most obvious upward trend in the whole process, whereas the fastest growth since 2012 was in hypertensive nephropathy. Conclusion: The proportion of SGD increased whereas PGD declined. IgAN remained the most common PGD, and HSPN was the most common SGD. MN and DN showed the most obvious upward trend among PGD and SGD, respectively. Changes in the spectrum of kidney disease, especially the constituent ratio of SGD, pose a great challenge to public health.

OBJECTIVE: Reduce the number of false alarms and measurement time caused by movement interference by the sync waveform of the movement. METHODS: Vital signal monitoring system based on motion sensor was developed, which collected and processed the vital signals continuously, optimized the features and results of vital signals and transmitted the vital signal results and alarms to the interface. RESULTS: The system was tested in many departments, such as digestive department, cardiology department, internal medicine department, hepatobiliary surgery department and emergency department, and the total collection time was 1 940 h. The number of false electrocardiograph (ECG) alarms decreased by 82.8%, and the proportion of correct alarms increased by 28%. The average measurement time of non-invasive blood pressure (NIBP) decreased by 16.1 s. The total number of false respiratory rate measurement decreased by 71.9%. CONCLUSIONS False alarms and measurement failures can be avoided by the vital signal monitoring system based on accelerometer to reduce the alarm fatigue in clinic.

OBJECTIVE: To investigate the role and underlying mechanism of human myeloid differentiation protein 2 (MD2) in the process of neuronal death induced by lipopolysaccharide (LPS) by establishing an in vitro model of sepsis-associated encephalopathy (SAE) by LPS. METHODS: Healthy C57BL/6J mice at 14-18 days of gestation were selected, and brain cortical tissue was taken from fetal mice. Neurons were stimulated with 0 (control), 1, 5 and 10 g/L of LPS for 24 hours. The release of lactate dehydrogenase (LDH) was detected and the death of neurons was observed. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of inflammatory factors interleukins (IL-6, IL-1β), in order to determine the optimal dose of LPS for establishing an in vitro neuroinflammation model of SAE. The cells were divided into blank control group and LPS group. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end-labeling (TUNEL) was used to discover apoptosis. Western blotting was used to detect the expression of the relevant protein markers activated caspase-3, necroptosis-associated protein neuronal receptor-interacting serine/threonine-protein kinase 3 (RIPK3) and phosphorylated RIPK3 (p-RIPK3). Immunofluorescence chemical staining was used to detect the expressions of p-RIPK3 and microtubule-associated protein 2 (MAP2) to evaluate the type of cell death and the degree of neuronal death. Western blotting was used to detect MD2 expression. Immunofluorescence chemical staining was performed to observe the expression and distribution of p-RIPK3 and MD2 in neurons to assess whether MD2 was involved in the inflammatory response promoting neuronal death. In addition, the cells were divided into blank control group, LPS group, and MD2 interfering peptide group (LPS+TC group), and the levels of IL-6, IL-1β and LDH were detected to evaluate whether interfering with MD2 can alleviate LPS induced neuroinflammation. RESULTS: 10 g/L LPS induced notable neuronal death, and the release of LDH in neurons stimulated with this concentration for 24 hours was significantly higher than that in the blank control group (relative release: 1.45±0.04 vs. 1.00±0.00, P < 0.01), indicating apoptosis and necroptosis occurred in neurons, and the levels of inflammatory factors IL-6 and IL-1β were remarkable increased [IL-6 (relative level): 1.94±0.04 vs. 1.00±0.00, IL-1β (relative level): 1.53±0.09 vs. 1.00±0.00, both P < 0.01]. Compared with the blank control group, the apoptosis of cells, cleaved-caspase-3 expression, the p-RIPK3/RIPK3 ratio, and p-RIPK3 expression around neurons in the LPS group were significantly increased [cleaved-caspase-3/GAPDH: 1.55±0.10 vs. 1.00±0.00, P < 0.01; p-RIPK3/RIPK3 ratio (relative value): 1.54±0.06 vs. 1.00±0.00, P < 0.05], which suggested that typical apoptosis and necroptosis apoptosis occurred in neurons in the septic environment. Furthermore, MD2 expression was significantly increased in the LPS group compared with the blank control group (MD2/GAPDH: 1.91±0.07 vs. 1.00±0.00, P < 0.01), and MD2 expression around neurons was increased, indicating that LPS-induced MD2 upregulation may play a key role in neuroinflammation and induction of neuronal death in sepsis. In addition, compared with the LPS group, the MD2-interfering peptide could reduce the expression levels of inflammatory factors IL-6 and IL-1β [IL-6 (relative level): 1.16±0.08 vs. 1.94±0.04, IL-1β (relative level): 1.15±0.05 vs. 1.75±0.09, both P < 0.01] and decrease LDH release (relative release: 1.09±0.01 vs. 1.44±0.04, P < 0.05). CONCLUSIONS LPS induced neuronal inflammatory responses via MD2, which ultimately leads to apoptosis and necroptosis. Interfering with MD2 reduces inflammation and inhibits neuronal death.

BACKGROUND: Red-cell transfusion is critical for surgery during the peri-operative period; however, the transfusion threshold remains controversial mainly owing to the diversity among patients. The patient's medical status should be evaluated before making a transfusion decision. Herein, we developed an individualized transfusion strategy using the West-China-Liu's Score based on the physiology of oxygen delivery/consumption balance and designed an open-label, multicenter, randomized clinical trial to verify whether it reduced red cell requirement as compared with that associated with restrictive and liberal strategies safely and effectively, providing valid evidence for peri-operative transfusion. METHODS: Patients aged >14 years undergoing elective non-cardiac surgery with estimated blood loss > 1000 mL or 20% blood volume and hemoglobin concentration <10 g/dL were randomly assigned to an individualized strategy, a restrictive strategy following China's guideline or a liberal strategy with a transfusion threshold of hemoglobin concentration <9.5 g/dL. We evaluated two primary outcomes: the proportion of patients who received red blood cells (superiority test) and a composite of in-hospital complications and all-cause mortality by day 30 (non-inferiority test). RESULTS: We enrolled 1182 patients: 379, 419, and 384 received individualized, restrictive, and liberal strategies, respectively. Approximately 30.6% (116/379) of patients in the individualized strategy received a red-cell transfusion, less than 62.5% (262/419) in the restrictive strategy (absolute risk difference, 31.92%; 97.5% confidence interval [CI]: 24.42-39.42%; odds ratio, 3.78%; 97.5% CI: 2.70-5.30%; P <0.001), and 89.8% (345/384) in the liberal strategy (absolute risk difference, 59.24%; 97.5% CI: 52.91-65.57%; odds ratio, 20.06; 97.5% CI: 12.74-31.57; P <0.001). No statistically significant differences were found in the composite of in-hospital complications and mortality by day 30 among the three strategies. CONCLUSION: The individualized red-cell transfusion strategy using the West-China-Liu's Score reduced red-cell transfusion without increasing in-hospital complications and mortality by day 30 when compared with restrictive and liberal strategies in elective non-cardiac surgeries.

Glioblastoma(GBM)is a lethal cancer with limited therapeutic options.Dendritic cell(DC)-based cancer vaccines provide a promising approach for GBM treatment.Clinical studies suggest that other immu-notherapeutic agents may be combined with DC vaccines to further enhance antitumor activity.Here,we report a GBM case with combination immunotherapy consisting of DC vaccines,anti-programmed death-1(anti-PD-1)and poly I:C as well as the chemotherapeutic agent cyclophosphamide that was integrated with standard chemoradiation therapy,and the patient remained disease-free for 69 months.The patient received DC vaccines loaded with multiple forms of tumor antigens,including mRNA-tumor associated antigens(TAA),mRNA-neoantigens,and hypochlorous acid(HOCl)-oxidized tumor lysates.Furthermore,mRNA-TAAAs were modified with a novel TriVac technology that fuses TAAs with a destabilization domain and inserts TAAs into full-length lysosomal associated membrane protein-1 to enhance major histo-compatibility complex(MHC)class Ⅰ and Ⅱ antigen presentation.The treatment consisted of 42 DC cancer vaccine infusions,26 anti-PD-1 antibody nivolumab administrations and 126 poly I:C injections for DC infusions.The patient also received 28 doses of cyclophosphamide for depletion of regulatory T cells.No immunotherapy-related adverse events were observed during the treatment.Robust antitumor CD4+and CD8+T-cell responses were detected.The patient remains free of disease progression.This is the first case report on the combination of the above three agents to treat glioblastoma patients.Our results suggest that integrated combination immunotherapy is safe and feasible for long-term treatment in this patient.A large-scale trial to validate these findings is warranted.

Objective: A multicenter Chinese mainland survey was conducted to investigate the sensitization distribution characteristics of cat, dog and horse dander in patients with allergic diseases, so as to provide clinicians with epidemiological data of common animal allergens and useful information for the prevention and treatment of allergies in cats, dogs and horses. Methods: The epidemiological investigation and design was adopted. This study is based on the national epidemiological survey of allergic diseases led by the first affiliated Hospital of Guangzhou Medical University. From January to December in 2021, a total of 2 122 patients diagnosed with allergic diseases were included in the outpatient department of respiratory department/pediatrics/allergy department of 14 units such as the First Affiliated Hospital of Guangzhou Medical University, and 222 healthy subjects were included as controls from the physical examination center of the above units in the same period. All the subjects filled out the allergic disease questionnaire under the guidance of doctors, and the allergen-specific immunoglobulin E (sIgE) of cats, dogs and horses of all subjects were detected by magnetic particle chemiluminescence system. The epidemiological characteristics of three animal allergens in different diseases, ages and regions were analyzed. Chi square test was used to analyze the frequency difference between groups, t test or Mann Whitney U test was used to test the distribution difference between two groups, and one-way ANOVA or Kruskal Wallis H test was used to compare the distribution difference between multiple groups. Bar chart, Venn-plot and radar chart were drawn to show the sensitization distribution characteristics. A small number of missing values caused by subjects' omission have been excluded during the analysis. Results: The 2 122 patients with allergic diseases were 57.35% male (1 217/2 122) and 40.95% female (869/2 122), and 1.70% (36/2 122) patients had loss of gender information. The age of patients with allergic diseases was 9.0 (6.0, 28.0) years, while that of healthy controls was 29.0 (13.0, 39.0) years old, and there were 1.7% (36/2 122) and 0.9% (2/222) subjects with missing age information, respectively. The proportion of caesarean section in allergic patients was significantly higher than that in healthy controls (31.4% vs. 17.6%,χ²=16.582,P<0.001) [2.5% (54/2 122) of the patient group and 5.4% (12/222) of the control group had missing birth mode information], and the proportion of patients with allergic diseases who reported that both parents had allergic diseases was significantly higher than that of the control group (35.7% vs. 9.5%, χ²=65.171,P<0.001). Patients with allergic diseases are mainly school-age (6-12 years old) and adolescents (12-18 years old). 16.4% of patients with allergic diseases were sensitized to cat dander, 10% and 6% to dog and horse dander. The sensitization rate of cat dander in patients with rhinitis, asthma, conjunctivitis, food allergy and atopic dermatitis was the highest (16.4%-21.6%), followed by dog dander (10.2%-15.2%). The prevalence of allergic rhinitis was the highest among different animal sensitized populations. The proportion of cat, dog and horse allergens sensitized at the same time is between 10%-15%, and the proportion of any two or more animal dander sensitized at the same time is about 45%. Animal allergens are associated with respiratory allergic diseases, especially allergic rhinitis with allergic conjunctivitis. There were significant differences in the distribution of positive rates of three animal allergens in different regions, and the highest positive rate of cat dander was found in all provinces of the country. Conclusion: The sensitization rate of animal dander allergens increased significantly, and the highest was in children and adolescents. Cat dander is the most common animal allergen, followed by dog. Different animals show obvious cross or common sensitization due to their high homology.

Infectious diseases of spine (IDS) refer to a series of infectious diseases in different parts of the spine (vertebral body, intervertebral disc, appendix of vertebra, spinal canal, and adjacent paravertebral tissues) caused by various pathogenic microorganisms, accounting for about 2%~7% of systemic musculoskeletal system infections. According to the classic classification IDS can be divided into two types: specific infection and non-specific infection. IDS often has an insidious onset, atypical clinical manifestations, and less-specific imaging and laboratory tests, which causes great difficulties for the accurate diagnosis and treatment, often leading to missed diagnosis, misdiagnosis, and even mistreatment. Problems such as disordered clinical diagnosis and treatment procedures, diverse treatment methods, and non-standard medication and course of treatment still affect the prognosis of IDS. This article reviews the current research progress of the diagnosis and treatment process of IDS, in order to further standardize the diagnosis and treatment process of IDS.

AIM: To compare the consistency and feasibility of objective ocular torsion measured with GMPE module-based optical coherence tomography(OCT)and fundus color photography(FCP).METHODS: Patients were enrolled in our strabismus clinic from December 2020 to March 2021, and the objective ocular torsion of the eyes was measured by both GMPE module-based OCT and FCP on the same day. FCP was used to measure the fovea-disc angle(FDA)manually by using the Adobe Photoshop software, while the GMPE module-based OCT software positioned automatically the macula and the center of the optic disc to measure the FDA.RESULTS: Fifty-five patients were included, the FDA measured by OCT was -6.6°±4.5° in the right eye and -8.8°±4.7° in the left eye, respectively; The FDA measured by FCP was -6.6°±4.7° in the right eye and -8.4°±4.1° in the left eye, respectively, with no statistically significant difference between the results of the two methods(Pright eye=0.90, Pleft eye=0.08). In patients with exotropia, the FDA measured by OCT was -5.8°±4.9° in the right eye and -9.1°±4.5° in the left eye, respectively, the FDA measured by FCP was -5.7°±5.0° in the right eye and -8.6°±4.3° in the left eye, respectively,(Pright eye=0.75, Pleft eye=0.15). Similarly, the patients with esotropia, the FDA measured by OCT was -9.0°±7.3° in the right eye and -11.3°±3.5° in the left eye, respectively, while the FDA measured by FCP was -10.0°±7.0° in the right and -10.1°±2.8° in the left eye(Pright eye=0.21, Pleft eye=0.10), respectively. There were no significant differences between the two methods in patients with esotropia or exotropia(P>0.05). The results of both Pearson test and Bland-Altman analysis were highly correlated(rright eye=0.93, rleft eye=0.94, P<0.01). CONCLUSION: GMPE module-based OCT can be used for objective ocular torsion measurement with high reliability and reproducibility, and is a promising clinical alternative to the fundus color photographic method.
