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.

ObjectiveBased on modern analytical techniques and a depressed mouse model established by chronic unpredictable mild stress（CUMS）， to evaluate the quality marker（Q-Marker） and pharmacodynamic difference of Baihe Dihuangtang prepared by different processes. MethodsHigh performance liquid chromatography（HPLC） was used to establish the characteristic profiles of Baihe Dihuangtang， and determine the content of Q-Marker in the samples prepared by ancient and modern processes. Seventy C57BL/6J mice were randomly divided into the normal group， model group， fluoxetine group（3 mg·kg^-1）， low and high dose groups of ancient process（6.5， 26 g·kg^-1）， and low and high dose groups of modern process（6.5， 26 g·kg^-1）， with 10 mice in each group. Except for the normal group， CUMS was used to induce depression in mice from the other groups for 28 d. After successful modeling， administration groups were given the corresponding drugs by gavage every day， and the normal and model groups were given an equal volume of pure water by gavage for 21 consecutive days. Change in body mass of mice was recorded， tail suspension test and open field test were used to evaluate the depressive behavior of mice， and enzyme-linked immunosorbent assay（ELISA） was employed to determine the contents of tumor necrosis factor-α（TNF-α）， interleukin（IL）-1β and IL-6 in serum. ResultsCharacteristic profiles of Baihe Dihuangtang prepared by the two processes were established， the similarity between the two was 0.951， and 8 characteristic peaks were recognized with the reference peak of regaloside A. The results of quantitative analysis showed that the Q-Marker content was similar in Baihe Dihuangtang prepared by ancient and modern processes. The results of pharmacodynamics showed that， compared with the normal group， the model group showed increased immobility time in the tail suspension test， reduced total movement distance in the open field test， and elevated IL-1β， IL-6 and TNF-α levels in the serum（P<0.01）. Compared with the model group， the behavioral indicators of mice in the Baihe Dihuangtang treatment group were significantly improved in terms of tail suspension time and open field exercise， and the levels of IL-1β， IL-6 and TNF-α in serum were significantly reduced（P<0.05， P<0.01）. Baihe Dihuangtang prepared by the two processes both had antidepressant effects， and the difference between the two was not statistically significant in improving depressive symptoms. ConclusionQ-Marker of Baihe Dihuangtang prepared by modern and ancient methods are equivalent in content， and the pharmacological effects are consistent， indicating that dried Lilii Bulbus can replace fresh products in the preparation of Baihe Dihuangtang. This study provides a scientific basis for the development of new drugs of Baihe Dihuangtang and a reference for its rational application and clinical use.

Glioma is the most common primary malignant tumor of the central nervous system in adults. Despite the standard treatment of surgery combined with radiotherapy and chemotherapy, the prognosis for high-grade glioma patients remains poor, highlighting the urgent need to further explore its pathogenesis and develop new therapeutic strategies. This article reviews the research progress in the field of glioma in China in 2024, covering tumorigenesis mechanisms, tumor immune microenvironment composition, advances in imaging techniques and novel imaging agents, improvements in surgical approaches, mechanisms of radio- and chemoresistance, and explorations of new therapeutic modalities. These studies provide a solid theoretical foundation for advancing clinical diagnosis and treatment of gliomas and may offer new opportunities to improve patient outcomes.

Objective: To investigate how Zuogui Jiangtang Qingzhi Formula (ZGJTQZF), a traditional Chinese medicine compound for lowering blood glucose levels and clearing lipids based on Zuogui Pill, regulates the cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING)/TANK-binding kinase 1 (TBK1) signaling pathway to improve type 2 diabetes mellitus combined with non-alcoholic fatty liver disease. Methods: According to fasting blood glucose (FBG) levels, body weight, and sex, 40 MKR mice, with half being male and the other half female, were randomly divided into four groups: blank, model, ZGJTQZF (29.6 g/kg), metformin + simvastatin ([65.0+ 2.6] mg/kg), 10 mice per group, and a normal group consisting of 10 age-matched FVB mice. Mice in all groups, except in the normal and blank groups, were fed a high-fat diet for 8 weeks to induce the disease model. Each group received daily gavage of the respective treatments for 8 weeks after successful modeling. Various parameters were measured, including FBG, liver function (alanine aminotransferase [ALT] and aspartate transaminase [AST]), and blood lipids (triglyceride [TG] and total cholesterol [TC]). Serum levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were determined using enzyme-linked immunosorbent assays. Histological liver changes were examined using transmission electron and optical microscope. cGAS, STING, and TBK1 protein and mRNA expression levels in liver tissues were detected using Western blotting and real-time PCR, respectively. Results: Compared with the normal group, the model group exhibited significant fat accumulation in hepatocytes and liver damage. Additionally, FBG, ALT, AST, serum TNF-α, IL-6, cGAS, STING and TBK1 expression levels in liver tissues were significantly elevated (P<0.05). Treatment with ZGJTQZF and metformin + simvastatin significantly improved FBG, ALT, AST, TG, TC, TNF-α, and IL-6 (P<0.01). Histologically, hepatic steatosis was notably alleviated. Expression of protein and mRNA of cGAS, STING, and TBK1 in liver tissues was significantly reduced (P<0.05). Conclusion ZGJTQZF improves lipid and glucose metabolism, mitigates liver injury, and reduces inflammatory markers in MKR mice. These effects may be mediated through the regulation of the cGAS/STING/TBK1 signaling pathway.

Objective To investigate the plasma levels of C1q/tumor necrosis factor-related protein 6(CTRP6)and systemic inflammation response index(SIRI)in patients with heart failure(HF)and their clinical significance.Methods 126 HF patients admitted to the Heart Center,the First Affiliated Hospital of Shihezi University from October 2023 to September 2024 were selected and divided into heart failure with reduced ejection fraction(HFrEF)group(n=43),heart failure with mildly reduced ejection fraction(HFmrEF)group(n=45)and heart failure with preserved ejection fraction(HFpEF)group(n=38)according to left ventricular ejection fraction(LVEF)value.Non-HF patients treated at the same period were selected as the control group(n=38).Blood routine,N-terminal pro-B-type natriuretic peptide(NT-proBNP)and echocardiogram parameters were collected,SIRI and left ventricular mass index(IVMI)were calculated,plasma CTRP6 levels were detected by enzyme-linked immunosorbent assay,and the correlation between CTRP6,SIRI and LVEF,IVMI,NT-proBNP and New York Heart Association grades in HF patients was analyzed.Risk factors of HF were analyzed by Logistic regression analysis and receiver operating characteristic(ROC)curve was drawn.Results Compared with control group,HF patients showed statistically significant increases in creatinine,uric acid,estimate glomerular filtration rate,and SIRI levels,as well as a higher proportion of patients with coronary heart disease and atrial fibrillation.Conversely,CTRP6 levels were decreased,with statistical significance(P＜0.05).There were statistical differences in CTRP6,NT-proBNP,LVEF and IVMI of HF patients with different ejection fraction classification(P＜0.05).Spearman correlation analysis showed that CTRP6 level was positively correlated with LVEF and negatively correlated with LVMI in HF patients.SIRI was positively correlated with NT-proBNP and negatively correlated with LVEF.Logistic regression analysis indicates that CTRP6 is independent protective factor for HF,and a decrease in CTRP6 is an independent risk factor for HF severity.The area under ROC curve of CTRP6,SIRI and their combined diagnosis HF are 0.762,0.772 and 0.850,respectively.Conclusion The plasma CTRP6 level in HF patients is significantly decreased,and SIRI is significantly increased.Both of them have good diagnostic value for HF patients,and their combined detection can improve the diagnostic efficiency.

Neuropathic pain (NP) is a chronic and intractable pain syndrome triggered by lesions or diseases of the somatosensory nervous system. It has a high incidence in the general population and currently lacks effective treatment methods, which seriously reduces the life quality of patients. Peripheral sensitization and central sensitization are the key mechanisms for the occurrence and development of NP. A variety of immune cells are involved in the processes of peripheral sensitization and central sensitization. After peripheral nerve injury, immune cells such as macrophages, astrocytes and Schwann cells infiltrate and release chemical substances. Through regulating inflammatory reactions and ion channels, they initiate and amplify pain signals, increasing the sensitivity of nociceptors to incoming signals and forming peripheral sensitization. Immune cells in the central nervous system, represented by microglia and astrocytes, are stimulated by pro-nociceptive substances released by primary afferent nerve fibers, enhancing their excitability. Subsequently, they synthesize and release pro-inflammatory cytokines, leading to the enhancement and remodeling of neuronal connections in the spinal cord and brain, resulting in central sensitization. This article reviews the role of immune cells and peripheral sensitization and central pain sensitization, providing a theoretical basis and practical guidance for the understanding and treatment of NP.

BACKGROUND:Polyamines play a crucial role in tissue calcification.Spermidine/spermine N1-acetyltransferase 1(SAT1),as a key rate-limiting enzyme regulating intracellular polyamine metabolism,has been associated with various pathological processes.However,its role in vascular calcification remains unclear.OBJECTIVE:To investigate the role of SAT1 in rat vascular smooth muscle cell calcification.METHODS:(1)Bioinformatics analysis:Differential expression of SAT1 in human carotid atherosclerotic plaques and their surrounding healthy carotid artery tissues were using GEO datasets.PanglaoDB database was used to analyze SAT1 expression abundance and localization across different cell types through single-cell sequencing.(2)Rat vascular smooth muscle cells were divided into three groups:a control group cultured in DMEM medium,a calcification group induced by DMEM medium containing 10 mmol/L β-glycerophosphate sodium and 3 mmol/L calcium chloride,and the 50,100 μmol/L diacetylaminotriazamidine groups treated with the SAT1 inhibitor,diacetylaminotriazamidine,in addition to the calcification medium.After 7-10 days of culture,alizarin red S staining was performed,and cellular calcium content and alkaline phosphatase activity were assessed.Western blot was used to detect the protein expression of Runt-related transcription factor 2,bone morphogenetic protein 2,alpha-smooth muscle actin,and SAT1.Immunofluorescence staining was conducted to examine the expression of Runt-related transcription factor 2 and SAT1.RESULTS AND CONCLUSION:(1)Bioinformatics analysis revealed significantly upregulated expression of SAT1 and Runt-related transcription factor 2(P<0.05)in carotid atherosclerotic plaques compared with healthy carotid tissues(P<0.05).Single-cell sequencing database analysis confirmed SAT1 expression in vascular smooth muscle cells.(2)Compared with the control group,the calcification group showed significantly increased Runt-related transcription factor 2,bone morphogenetic protein 2,SAT1,calcium content,and alkaline phosphatase activity,while alpha-smooth muscle actin expression was significantly decreased(all P<0.05).Compared with the calcification group,the 50 and 100 μmol/L diacetylaminotriazamidine groups showed significantly decreased Runt-related transcription factor 2,bone morphogenetic protein 2,calcium content,and alkaline phosphatase activity,while alpha-smooth muscle actin expression was significantly increased(all P<0.05).(3)Immunofluorescence experiments demonstrated that compared with the calcification group,the expression intensity of Runt-related transcription factor 2 was significantly reduced in the 50 and 100 μmol/L diacetylaminotriazamidine groups.Overall,SAT1 may promote vascular smooth muscle cell calcification by upregulating Runt-related transcription factor 2 expression.

Objective To investigate the effect of postoperative reduction quality in femoral neck fracture internal fixation on mechanical properties of the femoral head from the perspective of trabecular bone biomechanics.Methods From patients who underwent hip replacement surgery for femoral neck fractures,a total of 26 femoral head slice specimens were obtained.The central axis of the primary compressive trabeculae was defined as the 0° group,with the intersection point of the primary compressive trabeculae and the femoral calcar serving as the center.By rotating the specimens to simulate different reduction angles,the cut femoral head slice specimens were randomly divided into five groups:-10°,-5°,0°,5°,and 10°,representing femoral heads with varying reduction qualities.The specimens were subjected to single compression load tests and fatigue load tests.The load was set from 70 N to 1 400 N,at a frequency of 1 Hz,with 10 000 cycles.Axial stiffness,displacement,and the number of collapse cycles were measured,to compare the biomechanical properties of femoral head specimens under different reduction qualities.Results There were differences in the axial stiffness,displacement,and number of collapse cycles among the femoral head specimens in different groups.Under 800 N load,the axial stiffness of 0° group was significantly greater than that of±10° groups(P＜0.05).The axial stiffness of 0° group was also greater than that of the±5° groups,but the differences were not statistically significant(P＞0.05).The axial stiffness of±5° groups was greater than that of±10° groups(P＜0.05).0° group had a lower displacement than±5° groups and±10° groups.However,the differences in displacement between 0° group and±5° groups were not statistically significant(P＞0.05),while the differences between the 0° group and±10° groups were statistically significant(P＜0.05).The differences in displacement between±5° groups and±10° groups were also statistically significant(P＜0.05).0° group had a significantly higher number of collapse cycles than±10° groups(P＜0.05).The number of collapse cycles in 0° group was also higher than that in±5° groups,but the differences were not statistically significant(P＞0.05).The number of collapse cycles in±5° groups was significantly higher than that±10° groups(P＜0.05).Conclusions The quality of reduction after internal fixation of femoral neck fractures significantly affects the biomechanical properties of the femoral head.This study provides a scientific basis for optimizing treatment and postoperative management,aiming to improve clinical outcomes and patients' quality of life.
