Objective To explore an artificial intelligence (AI)-based method for automated hand hygiene monitoring and to compare the effectiveness of three algorithms (UniFormerV2, TDN, C3D) in recognizing hand hygiene steps in surgical settings, thereby aiding hospital infection control. Methods From April to October 2024, we non-invasively collected 641 video recordings of healthcare staff performing hand hygiene at four-bay scrub sinks in two tertiary hospitals using overhead HD cameras. The dataset was annotated by five trained experts for model training and validation. Results Following training on 385 samples, internal validation (n=119) showed the C3D model achieved 81% accuracy, 87% recall, and an 83% F1-score. The TDN model achieved 93%, 91%, and 92% for the same metrics. The UniFormerV2 model outperformed both, with an accuracy, recall, and F1-score of 93%—an improvement of over 10 percentage points compared to traditional CNNs (TDN, C3D). It also achieved an 84% accuracy in external validation, demonstrating strong generalization. Conclusion The UniFormerV2 model is more accurate than CNN-based models for hand hygiene step recognition and shows robust performance in external validation. It presents a viable tool for healthcare facilities to enhance hand hygiene management, ultimately improving medical quality and patient safety.

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 PM2.5 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 PM2.5 concentration varies in different regions, so targeted measures should be formulated according to the situation in different regions.

Continuous manufacturing, as an innovative pharmaceutical production model, offers advantages such as high production efficiency and ease of control compared to traditional batch production, aligning with the future trend of drug production moving toward greater efficiency and intelligence. However, the development of continuous manufacturing technology in wet granulation has been slow. On one hand, this is closely related to its high technical complexity, substantial equipment investment costs, and stringent process control requirements. On the other hand, the long-term use of the traditional batch production model has created strong path dependence, and the lack of mature standardized processes further increases the difficulty of technological transformation. To promote the deep integration of wet granulation technology with continuous manufacturing, this review systematically outlines the current application of wet granulation in continuous manufacturing. It focuses on the development of key technologies such as online detection, process modeling, and process scale-up, with the aim of providing a reference for process innovation and application in wet granulation.

Acute lung injury(ALI) is a critical clinical condition primarily characterized by refractory hypoxemia and infiltration of inflammatory cells in lung tissue, which can progress into a more severe form known as acute respiratory distress syndrome(ARDS). Immune cells and inflammatory cytokines play important roles in the progression of the disease. Due to its unclear pathogenesis and the lack of effective clinical treatments, ALI is associated with a high mortality rate and severely affects patients' quality of life, making the search for effective therapeutic agents particularly urgent. Ginseng Radix et Rhizoma, the dried root of the perennial herb Panax ginseng from the Araliaceae family, contains active ingredients such as saponins and polysaccharides, which possess various pharmacological effects including anti-tumor activity, immune regulation, and metabolic modulation. In recent years, studies have shown that ginsenosides exhibit notable effects in reducing inflammation, ameliorating epithelial and endothelial cell injury, and providing anticoagulant action, indicating their comprehensive role in alleviating lung injury. This review summarizes the pathogenesis of ALI and the molecular mechanisms through which ginsenosides act at different stages of ALI development. The aim is to provide a scientific reference for the development of ginsenoside-based drugs targeting ALI, as well as a theoretical basis for the clinical application of Ginseng Radix et Rhizoma in the treatment of ALI.

Systemic lupus erythematosus (SLE) may lead to secondary gynecological and obstetric disorders such as decreased ovarian reserve function, menstrual abnormalities, and adverse pregnancy outcomes. Based on "bi (痹) of both body and viscera" theory, this paper proposed that the core mechanism of SLE secondary gynecological and obstetric diseases lies in the mutual transformation between "body bi" and "viscera bi", which together affect the uterus. Physiologically, uterus forms an internal-external network with the body and viscera through the meridians and blood vessels. Pathologically, when the healthy qi is deficient, nourishment of the body and viscera is impaired; when toxins and stasis accumulate, pathogenic factors disturb the uterus through the chong (冲) and ren (任) meri-dians. The resulting obstruction in the uterus can, in turn, manifest externally and aggravate damage to the body and viscera. Therefore, the pathogenesis of SLE secondary gynecological and obstetric diseases follows a dynamic trajectory of "body bi first, body bi affecting viscera, and then bi of both body and viscera". In treatment, the principle of harmonizing and balancing the healthy qi is emphasized. The main approach is to regulate the viscera, stabilize the body, and nourish the uterus, with the coordination of nourishing the viscera through the body, thereby achieving simultaneous treatment of both body and viscera. This highlights the guiding significance of the "bi of both body and viscera" theory in preventing and treating SLE secondary gynecological and obstetric diseases.

ObjectiveTo investigate the syndrome evolution patterns, characteristics of the used herbal medicinals, and efficacy variations across different stages of rheumatoid arthritis (RA) progression. MethodsBased on the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN), 2,506 RA patients were retrospectively enrolled and categorized into <6 months group (166 cases), 6 months to <5 years group (1063 cases), 5 to <20 years group (1067 cases), and ≥20 years group (210 cases). Syndromes were differentiated before and after traditional Chinese medicine (TCM) treatment, including damp-heat obstruction, wind-damp obstruction, cold-damp obstruction, blood stasis obstructed in the collaterals, phlegm-stasis obstruction, liver-kidney insufficiency, qi and blood deficiency, and qi-yin deficiency. The syndrome evolution rate was calculated for high-frequency syndromes before and after treatment. Analysis was conducted on top 20 frequently used Chinese herbs at the first diagnosis. Clinical efficacy of the 28-joint disease activity score based on erythrocyte sedimentation rate (DAS28-ESR) and 28-joint disease activity score based on C-reactive protein (DAS28-CRP) before and after treatment were assessed. A multivariate logistic regression analysis was performed to identify factors affecting the efficacy of TCM treatment. ResultsPatients with course of disease shorter than 6 months predominantly presented with cold-dampness obstruction syndrome (49/166, 29.5%), wind-dampness obstruction syndrome (46/166, 27.7%), and dampness-heat obstruction syndrome (43/166, 25.9%). For patients with course of disease logner than 6 months and shorter than 5 years and those within 5 to 20 years, the dominant syndrome was dampness-heat obstruction syndrome (324/1063, 30.5% and 318/1067, 29.8%, respectively). In patients with disease duration ≥20 years, liver-kidney insufficiency syndrome and dampness-heat obstruction syndrome both predominated, each accounting for 25.24% (53/210). The syndromes with more than 100 cases before treatment and a syndrome evolution rate greater than 10% after treatment were dampness-heat obstruction (201/738, 27.2%), liver-kidney insufficiency (119/367, 32.4%), and phlegm-stasis obstruction syndromes (73/172, 42.4%). These were classified as high-frequency syndromes. After treatment, damp-heat obstruction syndrome and liver-kidney insufficiency syndrome primarily evolved into wind-damp obstruction syndrome, while phlegm-stasis obstruction syndrome evolved into damp-heat obstruction and cold-damp obstruction syndrome. The top two commonly used Chinese herbs across all groups were Gancao (Radix et Rhizoma Glycyrrhizae) and Baishao (Radix Paeoniae Alba). In the <6 months group and the 6 months to <5 years group, high-frequency herbs also included Fangfeng (Radix Saposhnikoviae), Duhuo (Radix Angelicae Pubescentis), Chuanxiong (Rhizoma Chuanxiong), and Qianghuo (Radix et Rhizoma Notopterygii). In the 5 to <20 years group and the ≥20 years group, the usage of Huangqi (Radix Astragali), Fuling (Poria), Niuxi (Radix Achyranthis Bidentatae), and Danggui (Radix Angelicae Sinensis) increased, while the proportion of Fangfeng and Duhuo decreased. After treatment, the DAS28-ESR and DAS28-CRP scores in all groups significantly decreased (P<0.05). There were statistically significant differences in clinical efficacy based on DAS28-ESR and DAS28-CRP across all groups (P<0.01). Multivariate logistic regression revealed significantly reduced treatment efficacy in the 6 months-5 years group (OR=0.4), 5~20 years group (OR=0.5), and ≥20 years group (OR=0.4) compared to the <6 months group. ConclusionRA syndromes follow a progression pattern from excess to deficiency, with corresponding transition in herbal usage from pathogen-eliminating to healthy qi-reinforcing approaches. TCM intervention can significantly reduce disease activity of RA, with superior efficacy in patients with disease duration shorter than 6 months.

OBJECTIVE:
To observe the efficacy and safety of 21-day venetoclax (VEN) plus azacitidine (AZA) (21-day VA) in newly diagnosed unfit acute myeloid leukemia (AML) patients in the real-world.
METHODS:
The clinical data of patients with unfit-AML who received 21-day VA regimen from December 2020 to July 2024 in our center and completed at least 1 cycle of therapeutic effect assessment was retrospectively collected to analyze the safety, efficacy and its influencing factors.
RESULTS:
A total of 59 patients were enrolled in our study, with a median age of 67(48-87) years old. After 1 cycle of therapy, the composite complete remission (cCR) rate was 74.5%, 54.2% of cases were negative for minimal residual disease (MRD). Among them, the MRD negative rate of patients with NPM1 mutation was significantly higher than that of patients without NPM1 mutation ( P =0.032). The median follow-up of patients was 19(2-38) months, the best cCR and MRD negative rates were 78% and 64.4%, respectively, the median overall survival (OS) time was 12 months, and the median progression free survival (PFS) time was 5 months. Multivariate Cox regression analysis showed less than 4 cycles of VA chemotherapy were independent risk factor for PFS and OS ( P < 0.05). After achieving remission, anemia and thrombocytopenia improved with the increase of the number of chemotherapy cycle.
CONCLUSION
In real-world, 21-day VA regimen still shows significant efficacy in the treatment of newly diagnosed unfit-AML, without adversely affecting remission rate and MRD negative rate of the first cycle.

Triple-negative breast cancer (TNBC) is a highly aggressive malignancy predominantly managed via chemotherapy. Our clinical sample analysis revealed a significant correlation between elevated CD24 expression in TNBC tumor cells and patient survival rates. We developed a novel antibody-drug conjugate (ADC), named HN03, consisting of an antibody with engineered cysteines for site-specific conjugation with a low toxic nitric oxide (NO) precursor as its payload through a novel Pt(IV)-mediated bioorthogonal self-cleavable linker. HN03 specifically targets tumor cells expressing high levels of CD24, concurrently generating cisplatin and releasing NO upon activation. HN03 also exhibited potent in vitro and in vivo antitumor activity. It significantly reduced tumor growth at various doses, prevented tumor metastasis, with markedly lower toxicity than traditional chemotherapy agents. We found that a key mechanism of its action involved inducing apoptosis and endoplasmic reticulum stress, substantially decreasing the number of M2-type macrophages. Overall, HN03 stands out as a promising therapeutic option for TNBC, offering a targeted treatment with reduced side effects and the potential for improved outcomes. Furthermore, using Pt(IV) in the linker and an NO precursor as the payload enhances the versatility of the Antibody-NO donor Conjugate (ANC), offering new avenues for the design of the next generation of ADCs.
