ObjectiveTo analyze the changes in infectious disease reporting timeliness before and after the implementation of the National Infectious Disease Intelligent Surveillance and Early Warning Pre-position Software (hereinafter referred to as “the pre-position software”) at Baoding Maternal and Child Health Hospital, and to evaluate its effectiveness in shortening reporting time and improving reporting timeliness. MethodsCase data of infectious diseases submitted by Baoding Maternal and Child Health Hospital to the National Disease Prevention and Control System during January to July 2024 (pre-implementation) and January to July 2025 (post-implementation) were selected. Overall differences in reporting timeliness between the two periods were compared, and stratified comparative analyses were performed by month, weekdays versus weekends/holidays, disease type, and population characteristics. ResultsBefore and after the implementation of the pre-position software, the hospital reported 623 and 587 infectious disease cases, respectively. Among the total 1 210 cases, 49.26% (596/1 210) had a reporting timeliness of <10 h. The highest number of reported cases fell into the 1 to <5 h range, accounting for 31.24% (378/1 210). There was a statistically significant difference in the composition of reported cases by reporting timeliness for infectious diseases in the hospital before and after the use of the pre-position software (χ²=27.38, P<0.001). Compared with January to July 2024, the median reporting timeliness in January to July 2025 was shortened by 3.77 h, and the difference was statistically significant (Z=-3.50, P<0.001). In April (the fourth month after implementation), the median reporting timeliness was shortened by 9.00 h (Z=-3.17, P=0.002). On non-working days (Saturdays and Sundays), it was shortened by 7.64 h (Z=-5.69, P<0.001), and on public holidays, it was shortened by 7.21 h (Z=-3.71, P<0.001). For class C infectious diseases, the median time was shortened by 3.49 h (Z=-3.05, P=0.002). For scattered children, it was shortened by 4.95 h (Z=-3.78, P<0.001). All differences were statistically significant. ConclusionAfter the implementation of the pre-position software, the reporting timeliness for infectious diseases at Baoding Maternal and Child Health Hospital is shortened, with particularly notable reductions observed in April, on non-working days, for Class C infectious diseases, and for scattered children, indicating the reporting timeliness is improved. This study provides empirical references for the promotion and application of this software in medical institutions.

BACKGROUND: Asthma, one of the most widespread chronic respiratory diseases, has placed a considerable economic and social stress on China. This study examines the burden of asthma in China from 1990 to 2021 and forecasts future trends, providing guidance for establishing focused preventive and regulatory strategies. METHODS: Utilizing data from the Global Burden of Disease Database 2021, the analysis of trends in asthma burden was conducted for China from 1990 to 2021. Key indicators such as incidence, prevalence, mortality, and disability-adjusted life years (DALYs) were analysed. The investigation applied the estimated annual percentage change (EAPC), average annual percentage change (AAPC), and age-period-cohort model (APCM) to evaluate these trends. Furthermore, predictions for incidence and mortality in 2035 were generated using the Bayesian APCM and the Nordpred model. RESULTS: In 2021, there were 25,015,668 prevalent asthma cases in China, alongside 3,934,875 new cases and 26,233 deaths. The age-standardized incidence rate and age-standardized death rate for 2021 were 364.17 (95% uncertainty interval [95% UI]: 283.22-494.1) per 100,000 population and 1.47 (95% UI: 1.15-1.79) per 100,000 population, respectively. The age-standardized rates (ASRs) for incidence were detected to be elevated in the 0-4 years age group, and the prevalence was significantly higher in the 5-9 years age group compared to other cohorts. ASR for incidence and prevalence of asthma in China were lower than that in the global average. Between 1990 and 2021, the ASR of incidence, prevalence, mortality, and DALYs demonstrated a downward trajectory, with EAPC values of -1.17, -1.57, -4.69, and -2.98, respectively. People aged 0-9 years and over 60 years experienced a disproportionately higher disease burden. Projections indicate that the ASRs for incidence will continue to rise, whereas the death will continue to decline by 2035. CONCLUSIONS Between 1990 and 2021, a general reduction in the asthma burden in China was observed. However, the burden remains particularly high among people aged 0-9 years and over 60 years, underscoring the need for targeted interventions and policies to address the ongoing challenges of asthma.

Objective:To evaluate the effect of Bu-Zhong-Yi-Qi-Tang (BZYQT) combined with low molecular weight heparin (LMWH) on lower limb deep vein thrombosis (DVT) after fracture fixation in aged rabbits.Methods:Thirty-two elderly New Zealand rabbits of either sex, aged 36 months, weighing 3.5-4.0 kg, were divided into 4 groups ( n=8 each) using the random number table method: control group (C group), fracture fixation group (F group), low molecular weight heparin group (L group) and BZYQT combined with LMWH group (BL group). A model of fixation surgery for right femoral shaft fracture was established in anesthetized rabbits in F, L and BL groups. Starting from postoperative day 1, BL group received BZYQT at 3.6 ml/kg via gavage, F and L groups received normal saline at 3.6 ml/kg via gavage, L and BL groups received subcutaneous injection of LMWH at 200 IU/kg, and all the administrations were performed daily at 08: 00 for 7 consecutive days. On postoperative day 7, ultrasound examination was performed to assess lower limb DVT. Blood samples were collected from the marginal ear vein for determination of the serum concentrations of cortisol (COR), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and endothelin-1 (ET-1) by enzyme-linked immunosorbent assay. Femoral vein specimens were obtained under anesthesia for microscopic examination of the pathological changes of the femoral vein lumen and endothelial tissues (by HE staining) and of the morphology of vascular endothelial cells (by the transmission electron microscopy). Results:Compared with C group, the concentrations of serum COR, TNF-α, IL-6 and ET-1 were significantly increased in F, L and BL groups, and the incidence of lower limb DVT within 7 days after surgery was significantly increased in F and L groups ( P<0.05). Compared with F group, the incidence of lower limb DVT within 7 days after surgery was significantly decreased in L and BL groups, and the concentrations of serum COR, TNF-α, IL-6 and ET-1 were significantly decreased ( P<0.05), and the pathological damage was significantly reduced in BL group. Compared with L group, the incidence of lower limb DVT and concentration of IL-6 were significantly decreased ( P<0.05), and pathological damage was significantly alleviated in BL group. Conclusions:BZYQT combined with LMWH can prevent the occurrence of lower limb DVT after fracture fixation in aged rabbits.

Lung cancer is one of the most prevalent malignant tumors,which incidence and mortality rates increasing annually.Development of drug resistance is a primary factor contributing to treatment failure.Tumor-associated macrophages(TAMs),as key immune cells within tumor microenvironment(TME),play a significant role in the emergence and progression of drug resistance in tu-mors.TAMs can polarize into two distinct subtypes,M1 and M2,in response to diverse signaling stimuli.Research indicates that M2 TAMs are closely associated with poor prognoses in lung cancer,facilitating drug resistance through mechanisms such as promoting angiogenesis,enabling immune evasion,inducing stem cell-like characteristics in tumors,modulating relevant signaling pathways,and secreting cytokines.Traditional Chinese medicine(TCM)is characterized by its multi-target approach and minimal toxic side effects,it has been shown to enhance tumor sensitivity to drugs,slow malignant progression,and extend patient survival.This paper reviews the relationship between TAMs and lung cancer drug resistance while summarizing current research on TCM and their active components that regulate TAM activity to mitigate drug resistance in lung cancer,aiming to provide new insights for targeting TAMs in this context.

OBJECTIVE To investigate the protective effect and potential mechanism of cornuside on diabetic nephropathy （DN） model mice. METHODS Male KK-Ay mice were fed with high-fat and high-sugar diet for two weeks to reproduce the DN model. The successfully modeled mice were randomly grouped into model group， aminoguanidine group （positive control，100 mg/kg） and cornuside group （100 mg/kg）， and male C57BL/6J mice were included as normal group， with 6 mice in each group. Administration groups were given relevant medicine intragastrically， and normal group and model group were given a constant volume of normal saline intragastrically， once a day， for 8 consecutive weeks. The levels of fasting blood glucose （FBG）， 24 h urinary protein， serum interleukin-12 （IL-12）， IL-10， blood urea nitrogen （BUN） and serum creatinine （Scr） were detected； the pathological injury， fibrotic change and glomerular microstructure of renal tissue were observed； the expressions of the receptor of advanced glycation end products （RAGE）， collagen type Ⅳ （COL-Ⅳ） and inducible nitric oxide synthase （iNOS） in renal cortex were detected in each group. RESULTS Compared with normal group， the renal cortex of mice in model group showed obvious inflammatory cell infiltration and fibrotic changes； the mesangial hyperplasia of glomerulus was serious and the basement membrane had a large number of irregular dark dense deposits； the levels of FBG and 24 h urinary protein， the serum levels of IL- 12， BUN and Scr， and the expression levels of RAGE， COL-Ⅳ and iNOS in the renal cortex were significantly increased， while the serum level of IL-10 was significantly decreased （P＜0.01）. Compared with the model group， the renal pathological injuries， fibrotic changes and glomerular microstructure of mice in administration groups were improved significantly， and the above quantitative indexes were generally improved （P＜0.05 or P＜0.01）. CONCLUSIONS Cornuside has a certain protective effect on DN model mice. It can inhibit the inflammatory response， reduce urinary protein excretion， and alleviate renal fibrosis， which may be related to the inhibition of the advanced glycation end products/RAGE signaling pathway.

The nasal swab samples of swine influenza(SI)suspected pigs were collected and tested for H3 subtype swine influenza virus(SIV)positive by RT-qPCR.The positive samples were inoc-ulated into SPF chicken embryos for virus isolation.The full genome sequencing and sequence anal-ysis of the isolated H3N2 subtype SIV were conducted,and its pathogenicity was studied.The re-sults showed that a strain of SIV was successfully isolated and identified as H3N2 subtype by RT-PCR,named A/Swine/Yunnan/KM/06/2023(H3N2).The BLSAT results showed that the eight segments of SIV H3N2 KM had the highest homology with eight different strains of swine influ-enza or human influenza viruses,reaching 95.41％-97.49％.The HA and NA segments were de-rived from H3N2 subtype SIV,the NP segment was derived from H1N1 subtype human influenza virus,the M segment was derived from H1N2 subtype SIV,and all other segments were derived from H1N1 subtype SIV.The key receptor sites(190D,223V,226I,228S)of HA protein remained unchanged.The pathogenicity experiment results showed that infected piglets exhibited symptoms such as fever,sneezing,runny nose,the virus could be detoxified to the outside through the nasal cavity,and the lungs had different degrees of lesion.Immunohistochemistry(IHC)showed that the virus could replicate in the lungs.In conclusion,a strain of H3N2 subtype SIV was successfully iso-lated,and the genetic evolution,molecular characteristics and pathogenicity of the virus were stud-ied.It revealed that H3N2 subtype SIV is constantly evolving and had pathogenicity to piglets,pro-viding a reference for monitoring and preventing SIV epidemics in China,and provided a candidate strain for SI vaccine development.
