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.

Objective To observe the effects of tactile/motor stimulation massage on feeding outcomes and neuromotor development levels of preterm infants.Methods A total of 136 preterm hospitalized infants in the neonatal intensive care unit of a tertiary hospital in Yunnan Province from January 2024 to July 2024 were enrolled and randomly assigned to a control group and an experimental group,with 68 cases in each group.The control group received the routine care for preterm infants,while the experimental group received tactile/motor stimulation massage as an intervention in addition to the routine care.The time taken from gavage to oral feeding(d),the rate of complete oral feeding(%),the incidence of feeding intolerance(%),the weight(g),the length(cm),the head circumference(cm),neonatal behavioral neurometric score(NBNA)and Psychomotor development index(PDI)were compared between the two groups.Results The time from gavage to oral feeding in the experimental group(12.73±1.86)days was significantly shorter than that in the control group(13.66±1.68)days,and the difference was statistically significant(P<0.05);the rate of complete oral feeding in the experimental group(89.7%)was significantly higher than that in the control group(70.6%),P<0.05,and the incidence of feeding intolerance in the experimental group(8.8%)was significantly lower than that in the control group(16.2%),P<0.05;The experimental group showed superior results in weight,length,and head circumference compared to the control group(P<0.05);The neonatal behavioral neurometry score of the experimental group(36.16±1.53)was significantly higher than that of the control group(35.10±2.66),P<0.05,and the motor development index in the experimental group(76.88±6.12)was significantly higher than that in the control group(74.34±5.07),P<0.05.Conclusion Tactile/motor stimulation massage can effectively improve the feeding status and promote the neuromotor development of preterm infants.

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.

The human microbiome encompasses a diverse array of microorganisms and their functional interactions within the human body. It exhibits a vast diversity of species and complex roles across various body environments. Advanced sequencing technologies, such as 16S amplicon sequencing and metagenomic sequencing, facilitate in-depth analysis on this microbial community. Recent researches have suggested that characteristics of the human microbiome (such as diversity and composition of microbiome, involving metabolic pathways and metabolites) might be associated with the onset and progression of cardiovascular diseases. These findings provide valuable insights into the etiology of chronic diseases and might aid in the development of novel disease biomarkers and intervention strategies. This paper summarizes the designs, current status and key findings of current population-based research in this field, and introduce the future development and analyze the existing critical problems that need further investigations.

Objective:Eosinophilic esophagitis (EoE), an allergen/immune-mediated chronic disorder of the esophagus, is witnessing an incremental rise in its global incidence. However, data in China are very limited. This study aimed to clarify the characteristics of EoE in Chinese adults at our medical center.Methods:We collected information, including clinical characteristics and endoscopic findings, relative to all cases of adult patients who met the pathological diagnostic criteria for EoE at our institution from January 2019 to May 2024. Patients diagnosed with reflux esophagitis (RE) were matched in a 1∶1 ratio based on age and sex, and comparisons were made between the two groups.Results:The overall detection rate of EoE in our hospital was approximately 0.05%, with a trend increasing yearly. In total, 61 patients met the diagnostic criteria for EoE, of whom 42 (68.9%) were male. The median age was 53 years. The clinical manifestations of EoE patients were diverse, with common symptoms including dysphagia, acid reflux, and upper abdominal pain. Serological examination revealed that 23.1% (9/39) of patients had increased absolute eosinophil counts. Allergic diseases were observed in 73.8% (45/61) patients. Most patients exhibited typical mucosal changes in the esophagus during endoscopy, the median EREFS score was 3 points. The most commonly administered treatment included proton pump inhibitors, and 13 patients received steroid treatment. During a follow-up period, 42 patients (68.9%) exhibited clinical symptom improvement or pathological remission. In comparison to Western countries, patients with EoE in China typically presented with milder disease severity and a more favorable prognosis. No significant differences were observed between younger and older adult groups regarding clinical symptoms, the proportion of comorbid allergic diseases, medications, or the rate of improvement ( P for all>0.05). Additionally, patients with EoE more commonly presented with dysphagia (29.5% vs. 1.6%, χ2=15.96, P<0.001), comorbid allergic diseases (73.8% vs. 13.1%, χ2=45.67, P<0.001), increased eosinophil counts (23.1% vs. 3.3%, χ2=7.61, P<0.01), and a positive response to corticosteroids when compared to patients with RE. Conclusions:This study systematically determined the clinical characteristics of adult EoE patients in China. Compared to Western countries, patients from China typically presented with milder disease severity and a more favorable prognosis. No significant clinical manifestations or prognosis differences were observed between younger and older patients. EoE can be differentiated from RE based on symptoms, the presence of comorbid allergic diseases, and the degree of serum eosinophil infiltration. For patients suspected of EoE, endoscopic esophageal biopsy will facilitate early diagnosis.

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.
