ObjectiveTo analyze the epidemiological characteristics of 8 major respiratory pathogens in influenza-like illness (ILI) cases with acute respiratory infections at fever clinics in Huangpu District, Shanghai from 2015 to 2024, and to provide a scientific basis for the prevention and treatment of respiratory diseases. MethodsA retrospective study was conducted in Huangpu District. Individuals meeting the case definition of ILI from 2015 to 2024 was registered. Their nasopharyngeal swabs were collected for pathogen detection. A total of 8 respiratory viruses were tested, including Influenza A virus (Flu A), Influenza B virus (Flu B), adenovirus (ADV), enterovirus/human rhinovirus (EV/HRV), human parainfluenza virus (HPIV), human coronavirus (HCoV), respiratory syncytial virus (RSV), and human metapneumovirus (HMPV). ResultsFrom 2015 to 2019, a total of 344 ILI cases were tested, of which 192 out of 344 cases (55.81%) were tested positive for single respiratory pathogen. From 2023 to 2024, 1 557 ILI cases were tested, with 572 out of 1 557 cases (36.74%) being positive for single pathogen. From 2023 to 2024, the positive rate of single pathogen in ILI cases was significantly lower than that in 2015‒2019 (χ²=42.66, P<0.001). Specifically, the positive rate of Flu A (χ²=74.43, P<0.001) decreased, while that of HPIV (χ²=8.66, P=0.003) increased, both with statistically significant differences. According to the seasonal pattern, the epidemic intensity of Flu A decreased in summer, while that of HPIV increased in summer and autumn. Demographic results showed statistically significant differences in the positive rates of EV/HRV between genders (χ²=22.38, P<0.001), with males exhibiting a higher positive rate than females. No statistically significant differences were identified in the positive rates of single pathogen among different age groups (χ²=4.42, P=0.110). Nevertheless, statistically significant differences were noted when comparing the positive rates of EV/HRV, Flu A, Flu B and HPIV across different age groups (P<0.05). EV/HRV was more commonly detected in the 15‒<25 age group (10.93%), while Flu A and HPIV had the highest positive rates in the ≥60 age group (21.24% and 4.77%). Flu B had the highest positive rate in the 25‒<60 age group (11.26%). 52.63% of cases with co-infections occurred during winter, with the primary pathogens involved being EV/HRV (9 cases) and HCoV (6 cases). The most prevalent combination of co-infection was Flu A with EV/HRV. ConclusionThe prevalence of respiratory pathogens among ILI cases from 2023 to 2024 exhibited notable fluctuations compared to that from 2015 to 2019. Therefore, influenza surveillance should be strengthened, and attention should also be paid to the prevalence of respiratory pathogens such as HPIV. These findings have profound implications for future research, surveillance, vaccine planning, and public health policy making.

ObjectiveTo investigate the differences in clinical features and mortality rate between native patients with chronic liver failure （CHF） and migrated patients with CHF after treatment with double plasma molecular adsorption system （DPMAS） in high-altitude areas. MethodsA total of 63 patients with CHF who received DPMAS treatment in the intensive care unit of General Hospital of Tibet Military Command from January 2016 to December 2021 were enrolled， and according to their history of residence in high-altitude areas， they were divided into native group with 29 patients and migrated group with 34 patients. The two groups were compared in terms of baseline data and clinical features before and after DPMAS treatment. The independent-samples t test was used for comparison of normally distributed continuous data between groups， and the paired t-test was used for comparison before and after treatment within each group； the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups， and the Wilcoxon signed rank sum test was used for comparison before and after treatment within each group； the chi-square test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to plot survival curves， and the Log-rank test was used for comparison of the risk of death. ResultsCompared with the native group， the migrated group had a significantly higher proportion of Chinese Han patients （χ²=41.729， P<0.001）， and compared with the migrated group， the native group had a significantly longer duration of the most recent continuous residence in high-altitude areas （Z=3.364， P<0.001）. Compared with the native group， the migrated group had significantly higher MELD score and incidence rates of hepatic encephalopathy， hepatorenal syndrome， and gastrointestinal bleeding （Z=2.318， χ²=6.903， 5.154， and 6.262， all P<0.05）. Both groups had significant changes in platelet count （PLT）， hemoglobin count （HGB）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， albumin， total bilirubin （TBil）， direct bilirubin （DBil）， lactate dehydrogenase （LDH）， creatinine （Cr）， and international normalized ratio （INR） after DPMAS treatment （all P<0.05）. Before DPMAS treatment， compared with the native group， the migrated group had significantly higher levels of ALT， AST， TBil， DBil， LDH， Cr， BUN， and INR （all P<0.05） and a significantly lower level of HGB （P<0.05）； after DPMAS treatment， compared with the native group， the migrated group had significantly greater reductions in PLT and HGB （both P<0.05） and still significantly higher levels of ALT， AST， TBil， DBil， LDH， BUN， and INR （all P<0.05）. The 60-day mortality rate of patients after DPMAS treatment was 52.5% （95% confidence interval ［CI］： 41.7 — 63.8） in the native group and 81.3% （95%CI： 77.9 — 85.6） in the migrated group. Compared with the native group （hazard ratio ［HR］=0.47， 95%CI： 0.23 — 0.95）， the migrated group had a significant increase in the risk of death on day 60 （HR=2.14， 95%CI： 1.06 — 4.32， P=0.039）. ConclusionCompared with the native patients with CHF in high-altitude areas， migrated patients have a higher degree of liver impairment， a lower degree of improvement in liver function after DPMAS treatment， and a higher mortality rate. Clinical medical staff need to pay more attention to migrated patients with CHF， so as to improve their survival rates.

OBJECTIVE To study the effects of Phellodendron amurense polysaccharides （PAP） on improving gouty nephropathy （GN） in rats， and to investigate its mechanism primarily by interfering the p38 mitogen-activated protein kinase （p38 MAPK）/nuclear factor-κB（NF-κB）/tumor necrosis factor-α（TNF-α）. METHODS Sixty rats were randomly divided into normal group （water）， model group （water）， allopurinol group （positive control， 20 mg/kg）， PAP high-dose， medium-dose and low-dose groups （100， 50， 25 mg/kg， by raw material） after being stratified by body weight， with 10 rats in each group. Except for the normal group， the other groups were induced to construct GN model by giving 1 500 mg/kg potassium oxazinate and 100 mg/kg adenine intragastrically for 14 days. After modeling， the rats in each group were given relevant medicine/water intragastrically， once a day， for consecutive 28 days. After the last medication， the levels of biochemical parameters related to renal function [uric acid， creatinine （Cr）， blood urea nitrogen （BUN）， xanthine oxidase （XOD）] were detected in rats， and the histopathological changes in the rat kidney were observed. The protein expressions of monocyte chemoattractant protein-1（MCP-1），TNF-α and interleukin-6（IL-6） as well as the phosphorylation levels of p38 MAPK and NF-κB p65 protein were determined in renal tissue of rats. RESULTS Compared with the normal group， the model group suffered from the dilatation of renal tubules， structural damage to glomeruli， accompanied by inflammatory infiltration and fibrosis； the contents of uric acid， Cr， BUN and XOD， the protein expressions of MCP-1，TNF-α and IL-6 and the phosphorylation levels of p38 MAPK and NF-κB p65 protein were all increased significantly （P＜0.05 or P＜0.01）. Compared with the model group， the pathological symptoms of renal tissue in rats had been improved to varying degrees in different dose groups of PAP； the contents of uric acid， Cr， BUN and XOD， protein expressions of MCP-1， TNF-α and IL-6， the phosphorylation levels of p38 MAPK and NF-κB p65 protein in PAP high-dose and PAP medium-dose groups were all decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS PAP exhibits an anti-GN effect， the mechanism of which may be associated with inhibiting the p38 MAPK/NF-κB/TNF-α signaling pathway.

As a common respiratory disease in children, asthma affects children′s physical and mental health and increases the burden on families and society.Patients with asthma can have one or more comorbidities, and these asthma comorbidities not only make the diagnosis of asthma more difficult, but also affect the control and treatment and outcome of the disease.However, asthma comorbidities are often under-recognized and poorly-managed.Therefore, it is important to improve the understanding of asthma comorbidities and to correctly identify, diagnose and treat them.Asthma in children contains a variety of comorbidities.This article reviews the research progress of epidemiology, impact on asthma and the treatment of these common comorbidities of asthma in children.

Objective:To explore the risk factors of hypotension in patients with hemodialysis-related superior vena cava diseases.Methods:This was a retrospective cohort study. The maintenance hemodialysis patients diagnosed as superior vena cava stenosis ≥50% or occlusion in West China Hospital of Sichuan University from January 1, 2019 to March 31, 2022 were selected. The patients were divided into hypotensive group and non-hypotensive group according to the occurrence of hypotension during non-dialysis period. The differences of general clinical data, cardiac ultrasound parameters and blood biochemical indexes between the two groups were compared. Multivariate logistic regression model was used to analyze the risk factors of hypotension in patients with hemodialysis-related superior vena cava lesions.Results:A total of 202 patients with hemodialysis-related superior vena cava lesions were included, of whom 84 patients (41.6%) developed hypotension during non-dialysis. Compared with the non-hypotensive group, patients in the hypotensive group had longer dialysis age ( Z=2.093, P=0.036), shorter left atrial diameter ( t=2.316, P=0.022), lower aortic valve orifice flow rate ( t=3.702, P=0.001) and serum calcium ( t=2.320, P=0.021), thicker left ventricular posterior wall ( t=3.042, P=0.003), lower proportions of hypertension history ( χ2=9.125, P=0.003), and higher proportion of residual superior vena cava ≤30% or occlusion ( χ2=8.940, P=0.003) and azygous vein opening ( χ2=11.067, P=0.001). Multivariate logistic regression analysis results showed that no history of hypertension ( OR=0.383, 95% CI 0.156-0.943, P=0.037), slow aortic valve orifice flow ( OR=0.207, 95% CI 0.062-0.695, P=0.011) and low blood calcium ( OR=0.236, 95% CI 0.066-0.841, P=0.026) were the independent influencing factors of hypotension in patients with hemodialysis-related superior vena cava diseases. Conclusions:Hemodialysis patients with severe stenosis or occlusion of the superior vena cava during non-dialysis have a higher risk of hypotension. No history of hypertension, slow aortic valve orifice flow, and low blood calcium are the independent risk factors of hypotension in patients with hemodialysis-related superior vena cava diseases.

OBJECTIVE：To explore the mechanism of Hippophae rhamnoides in the treatment of Alzheimer ’s disease （AD）， and to provide theoretic reference for further exploring the material basis. METHODS ：TCMSP，Uniprot，GeneCards database were used to screen the active components of H. rhamnoides ，targets and AD-related target gene. The “ingredients-targets-related diseases”network was constructed by Cytoscape 3.7.1 software. STRING database was adopted to construct protein interaction （PPI）network，molecular docking was conducted between the potential targets with high degree values and active components of H. rhamnoides . The gene ontology （GO）analysis and Kyoto encyclopedia of genes and genomes （KEGG）pathway enrichment analysis were performed by Clue GO for the potential target of H. rhamnoides in the treatment of AD. Totally 50 mice were randomly divided into blank group ，model group [ D-galactose 120 mg/（kg·d），AlCl3 solution 20 mg/（mL·d）]，positive drug group [oxiracetam 260 mg/（kg·d）]，seabuckthorn oil extract group [ 1.6 g/（kg·d）]，seabuckthorn polyphenols group [1.6 g/（kg·d）]，with 10 mice in each group. The mice was given relevant medicine intragastrically and modeling agent ；blank group was given constant volume of distilled water intragastrically ，once a day ，for consecutive 60 d. The learning and memory abilities were detected by Morris water maze test ；the levels of immune factors in hippocampus tissue were measured by ELISA. Pathological morphology of hippocampus tissue was observed by HE staining. The mechanism of H. rhamnoides in the treatment of AD was validated preliminarily. RESULTS ：Totally 22 active components of H. rhamnoides （quercetin，kaempferol，isorhamnetin， β-carotene，β-sitosterol） may affect biological processes such as nuclear receptor activity ，lipopolysaccharide-mediated signal pathway，and may affect 114 methabolism pathways such as IL- 17 signal transduction pathway ，TNF signal transduction pathway by regulating 147 targets such as serine/threonine kinase coding protein （AKT1），amino terminal kinase （JUN）and mitogen activated protein kinase （MAPK1）. The results of molecular docking showed that binding scores of the main active components of H. rhamnoides and the main target proteins were all above 4.25，which showed good binding activity. Results of pharmacology experiment showed that H. rhamnoides extract could shorten the escape latency of AD model mice ，increased the times of crossing platform，relieved hippocampus injury of cerebral tissue ，and decreased the contents of inflammatory factors TNF-α，IL-1β，IL-6 and IL- 17 in hippocampus of cerebral tissue. CONCLUSIONS ：The active components of H. rhamnoides can regulate multiple targets in the important pathway of AD ；animal experiments preliminarily verify that H. rhamnoides can relieve the hippocampus injury and improve the learning and memory ability of AD model mice by inhibiting the expression of inflammatory factors.

Objective To understand the current status and change trend of violence against children in China and provide evidence for the risk factor and intervention priority identifications and intervention strategy development.Methods The data of National Injury Surveillance System (NISS) from 2006 to 2015 were used to analyze the change in outpatient visit due to violence against children,injury cases' demographic characteristics,incidence of injury and clinical outcomes of injury cases.Results A total of 44 319 injury cases caused by violence against children were reported through NISS during this period.The proportion of violence related child injury cases in total child injury cases decreased year by year.In child violence cases reported in 2015,boys accounted for 81.31％,the boy to girl ratio was 2.22 ∶ 1.Violence related injuries caused by blunt strike accounted for 65.69％.The incidences of child violence were low in February and during July-August and 48.87％ of violence related injuries occurred in schools and public places,bruise accounted for 63.52％.The main injured body part caused by child violence was head (51.18％),and most violence caused injuries (82.66％)were mild,while 83.21％ of the injury cases went home after treatment.Conclusions Violence against children should not be ignored.Male students of middle/high schools are at high risk.Schools are the places where violence against children is prone to occur.Health and safety education should be strengthened to prevent the occurrence of campus violence and improve the child' s awareness of self-protection and reduce the incidence of serious violence.
