Objective To study the spatial distribution of the incidence of pulmonary tuberculosis in Hubei Province and its influencing factors, so as to improve the theoretical basis for scientific development of tuberculosis prevention and control measures in the future. Methods The data of reported incidence of tuberculosis and related influencing factors in various counties and districts of Hubei Province in 2020 were collected. Global Moran's I index, hotspot analysis and geographically weighted regression (GWR) model analysis were used to calculate the spatial autocorrelation of the incidence of tuberculosis, and to analyze the influencing factors affecting the incidence rate of tuberculosis. Results There were obvious regional differences in the space distribution of the incidence rate of tuberculosis. Hot spot analysis showed positive spatial correlation and obvious clustering. The GWR model (AICc=784.251) in this study had higher AICc value compared to the ordinary least squares regression (OLS) model (AICc=804.2585). The GWR model showed that the increase in the proportion of the population aged 65 and above and the proportion of the ethnic minority population had a significant promoting effect on the increase of the incidence rate of tuberculosis, and there was significant spatial heterogeneity. The effect of PM_2.5 concentration on the incidence rate of pulmonary tuberculosis varied in different regions, and the degree of effect was also different. Conclusion The proportion of people aged 65 and above and the proportion of ethnic minorities may significantly influence the incidence of pulmonary tuberculosis. The effect of PM_2.5 concentration varies in different regions, so targeted measures should be formulated according to the situation in different regions.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

The translocator protein (TSPO) positron emission tomography (PET) can noninvasively detect neuroinflammation associated with epileptogenesis and epilepsy. This study explored the role of the TSPO-targeting radioligand [¹⁸F]F-TFQC, an m-trifluoromethyl ER176 analog, in the PET neuroimaging of epileptic rats. Initially, [¹⁸F]F-TFQC was synthesized with a radiochemical yield of 8%-10% (EOS), a radiochemical purity of over 99%, and a specific activity of 38.21 ± 1.73 MBq/nmol (EOS). After determining that [¹⁸F]F-TFQC exhibited good biochemical properties, [¹⁸F]F-TFQC PET neuroimaging was performed in epileptic rats at multiple time points in various stages of disease progression. PET imaging showed specific [¹⁸F]F-TFQC uptake in the right hippocampus (KA-injected site, i.e., epileptogenic zone), which was most pronounced at 1 week (T/NT 1.63 ± 0.21) and 1 month (T/NT 1.66 ± 0.20). The PET results were further validated using autoradiography and pathological analysis. Thus, [¹⁸F]F-TFQC can reflect the TSPO levels and localize the epileptogenic zone, thereby offering the potential for monitoring neuroinflammation and guiding anti-inflammatory treatment in patients with epilepsy.

Optical genome mapping (OGM) is a novel non-sequencing genetic analysis technology that enables high-precision analysis of structural variations across the entire genome. It possesses unique technical advantages, and its procedural simplicity makes it easy to implement. In recent years, the application efficacy of OGM technology in the analysis of genomic structural variations in hematologic malignancies has been widely validated and recognized. Increasing evidence indicates that the application of OGM technology can help improve the genetic diagnosis, prognostic stratification and treatment guidance of hematologic malignancies. This article draws upon pertinent reports from the 65th American Society of Hematology Annual Meeting to provide an overview of the progress in applying OGM technology for the precise diagnosis and treatment of hematologic malignancies.

FLT3 internal tandem duplication (ITD) mutations are common in acute myeloid leukemia and show an important significance in guiding prognostic stratification and targeted therapy. With the widespread application of high-throughput sequencing technology and the increased ability to analyze mutation sequences, it has been found that more than half of FLT3-ITD mutations are not just tandem duplications but are also accompanied by some complex situations such as the addition of non-template sequences. Recent studies have revealed the sequence characteristics, mutagenesis mechanisms and related clinical prognostic significance of FLT3 length mutations (FLT3-LM). FLT3-LM with added non-template sequences is formed by abnormally activated terminal deoxynucleotidyl transferase. These patients show different treatment responses and prognosis when treated with chemotherapy, targeted therapy, and allogeneic hematopoietic stem cell transplantation, which provides a new perspective to understand FLT3-LM mutations more accurately and provides proposals for FLT3-LM typing based on the mutagenesis mechanism. The new typing rules can better reflect the differences in biological characteristics of the disease and more accurately guide the prognostic stratification and development of individualized treatment for patients with FLT3-LM mutations.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Objective:To investigate the effect of puerarin on myocardial inflammation in rats with heart failure from the Toll-like receptor 4(TLR4)/nuclear transcription factor-κB(NF-κB)inflammatory pathway.Methods:The rat model of heart failure was established by subcutaneous injection of isoproterenol(5 mg/kg for 7 days),and was divided into model group,puerarin group,TLR4 activator group(RS09,25 μg/kg),TLR4 inhibitor group(TAK-242,0.5 mg/kg),puerarin+TLR4 activator group,with 20 rats in each group.Another 20 rats were selected as normal control group.Echocardiography was used to detect heart function;HE staining was used to observe pathological damage of myocardial tissue;TUNEL method was used to detect apoptosis of myocardial tissue cells;ELISA method was used to detect the levels of inflammatory factors IL-6,IL-1β and tumor necrosis factor-α(TNF-α)in myocardial tissue;immunohistochemical method was used to detect the expression of TLR4 and macrophage activation marker-F4/80;Western blot was used to detect the protein expressions of TLR4/NF-κB pathway,MyD88,IL-1 receptor-associated kinase(IRAK)and Galec-tin-3.Results:Compared with the normal control group,the necrosis,inflammatory infiltration and apoptosis of rat myocardial cells were severe in the model group,the heart function was decreased,the inflammatory factor release,macrophage activation,and TLR4/NF-κB pathway protein expression were increased(P<0.05).Puerarin and TLR4 inhibitors could improve the pathological damage of heart failure rats such as myocardial cell necrosis,inflammatory infiltration and apoptosis to the same extent,improve heart function,reduce inflammatory response,inhibit macrophage activation and reduce TLR4/NF-κB pathway activation(P<0.05).TLR4 activator could promote the activation of TLR4/NF-κB pathway,aggravate myocardial cell damage,apoptosis and cardiac function damage in rats with heart failure,and weaken the above-mentioned effects of puerarin(P<0.05).Conclusion:Puerarin may inhibit the activation of TLR4/NF-κB pathway,reduce myocardial inflammation,and play an anti-heart failure effect.

Objective:To assess the capability of seven reference medical laboratories to detect BCR::ABL1 p210 transcription levels and to compare the results among those laboratories.Methods:The interlaboratory comparison was carried out in two stages. The samples were prepared by the reference laboratory. The quantitative values of BCR::ABL1 p210 of the comparison samples covered 0.001%-0.01%, 0.01%-0.1%, 0.1%-1%, 1%-10% and>10% in each stage. Real-time quantitative PCR (RT-PCR) and dPCR (digital PCR) were used to examine the samples. The conversion factor (CF) was calculated and validated for each laboratory.Results:In the RT-PCR comparison, one laboratory was failed to detect BCR::ABL1 p210 in fourteen samples at the first stage. The results of the other six laboratories were qualified with the bias <±1.2 folds (-0.133-0.338) and 95% limits of agreement within ±5 folds (upper limit 0.147-0.785, lower limit -0.770--0.109), and the corresponding CF values were calculated and validated. In the dPCR comparison, one laboratory did not report results at the second stage. The results of the other six laboratories were qualified with the bias <±1.2 folds (-0.026-0.267) and 95% limits of agreement within±5 folds (upper limit 0.084-0.991, lower limit -0.669--0.135), and the corresponding CF values were calculated and validated. The samples with BCR::ABL1 p210 quantitative values of 0.01%-0.1%, 0.1%-1%, 1%-10% and >10% could be detected by both RT-PCR and qPCR. When the quantitative value of BCR::ABL1 p210 was 0.001%-0.01%, the detection rate of dPCR was higher than that of RT-PCR (85.56% vs. 68.00%).Conclusions:A good consistency is present among various laboratories. The quantitative value of BCR::ABL1 p210 is comparable among laboratories as shown by the CF value conversion. For quantitative detection of BCR::ABL1 p210 deep molecular reaction, dPCR has a higher positive detection rate and more advantages than RT-PCR. To ensure the accuracy and reproducibility of the BCR::ABL1 p210 test, it is imperative for every laboratory to enhance their daily quality control practices.
