Direct compression is an ideal method for tablet preparation, but it requires the powder's high functional properties. The functional properties of the powder during compression directly affect the quality of the tablet. 15 parameters such as Py, FES-8KN, FES-12KN, FES-16KN, CR-8KN, CR-12KN, and CR-16KN were used as the characteristic variables in this paper. Unsupervised learning methods like principal component analysis, cluster analysis, and factor analysis were applied to analyze and classify the compression behavior data of 36 traditional Chinese medicine powders. The results showed that both different dimensionality reduction classification methods could effectively differentiate the compression behavior characteristics of 36 traditional Chinese medicine compound powders. The hierarchical cluster analysis results showed a better agreement with the actual compression phenomena of the powders, where group 1 was high elasticity and low compressibility, group 2 was easily compressed and hard to break, group 3 was excellent compressibility and compactibility. This study is expected to provide references and ideas for predicting the behavior of traditional Chinese medicine powders and the screening of tablet formulations.

Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.

Biomolecular condensates are formed through phase separation of biomacromolecules such as proteins and RNAs. These condensates exhibit liquid-like properties that can futher transition into more stable material states. They form complex internal structures via multivalent weak interactions, enabling precise spatiotemporal regulations. However, the use of inconsistent and non-standardized terminology has become increasingly problematic, hindering academic exchange and the dissemination of scientific knowledge. Therefore, it is necessary to discuss the terminology related to biomolecular condensates in order to clarify concepts, promote interdisciplinary cooperation, enhance research efficiency, and support the healthy development of this field.

OBJECTIVE To explore the construction of selection system for drug directory of the county-level medical community based on multi-criteria decision analysis， and provide decision-making basis for the selection of drug directory of medical community. METHODS Taking county-level medical community in Chongqing as an example，Delphi method and analytic hierarchy process were employed to construct the selection system for drug directory of the county-level medical community. Selected drugs were quantitatively scored based on the constructed index system， and the drug directory was selected according to the drug’s comprehensive score. The implementation effect of the directory was then evaluated through questionnaire surveys one year after the implementation of the directory. RESULTS The expert authority coefficients of the two rounds of consultation were＞ 0.8， with Kendall’s W values of 0.213 and 0.196， respectively （P＜0.001）. Finally， the selection system for drug directory of the medical community was determined to include five evaluation dimensions： safety， effectiveness， economy， accessibility， and innovation， along with eight evaluation indicators. In the drug directory selected according to the above method， the proportions of centrally procured drugs， medical insurance drugs， and essential drugs had all increased compared to before the selection； the comprehensive scores of chemical drugs ranged from 50.25 to 96.31 scores， and the proportion of drugs scoring between 70 and 100 scores had increased from 78.06% before selection to 85.82%. Among them， antiparasitic drugs had the highest comprehensive scores， while drugs for the digestive tract and metabolism were the most numerous. The evaluation scores of each indicator and the comprehensive scores of drugs in the drug directory after the selection process increased significantly than before selection （P＜ 0.05）. CONCLUSIONS The selection system for drug directory of the county-level medical community constructed in this study is scientific， objective and operable. This process facilitates the promotion of standardized and unified management of drugs in the medical community.

Objective To understand the situation of dental cone beam computed tomography (CBCT) quality control testing phantoms in radiation health technical service institutions in Guangdong province, analyze the differences among different phantoms, and provide a reference for dental CBCT quality control testing. Methods The testing phantoms of 49 radiation health technical service institutions were used as the research objects. The designated CBCT equipment was used for scanning and imaging. The Z-score method was used to evaluate the high-contrast resolution, low-contrast resolution, and distance measurement deviation of each phantom. Results The satisfaction rates of various items for the phantoms in 49 institutions ranged from 85.7% to 100%. The distance measurement deviations of four institutions were “suspicious”, and the high-contrast resolution of four institutions and the distance measurement deviation of one institution were “unsatisfactory”. Conclusion The overall performance of dental CBCT quality control testing phantoms in radiological health technical service institutions in Guangdong province is satisfactory. However, there are still some phantoms with poor results in items such as distance measurement deviation and high-contrast resolution. The structural design, material selection, and manufacturing process of the phantom may all affect the results of quality control testing. Therefore, appropriate phantoms, optimized exposure conditions, and suitable reconstruction algorithms should be used in CBCT quality control testing to ensure accurate and reliable measurements.

ObjectiveTo investigate the anatomical features of three-dimensional （3D） reconstruction of the hepatic pedicle based on the Laennec’s capsule， as well as its application value in the development of extra-sheath dissection/occlusion clamp and precise hepatectomy. MethodsA retrospective analysis was performed for the abdominal contrast-enhanced CT data of 100 patients without anatomical abnormalities of the hepatic pedicle in The General Hospital of Western Theater Command from January 2021 to June 2024. The Hisense CAS system combined with the 3D U-net deep learning algorithm was used for 3D reconstruction of the hepatic pedicle at the level of Laennec’s capsule， and the hepatic pedicle was measured in terms of the length， outer diameter， and angle of the main trunk and branches. An extra-sheath hepatic pedicle dissection/occlusion clamp was developed based on the above measurements， and a total of 30 patients scheduled for right hemihepatectomy were enrolled and randomly divided into device group and control group， with 15 patients in each group. The two groups were compared in terms of hepatic pedicle handling time， time of operation， intraoperative blood loss， and the incidence rate of bile duct injury. The independent-samples t test was used for comparison of continuous data between two groups， and the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsThe results of 3D reconstruction revealed four variants in the main trunk branches of the hepatic pedicle， with type Ⅰ （left-right branching） accounting for 88% （88/100）， type Ⅱ （trifurcation type） accounting for 5% （5/100）， type Ⅲ （right anterior branching） accounting for 5% （5/100）， and type Ⅳ （special type） accounting for 2% （2/100）. The outer diameter of the main hepatic pedicle was 24.10±6.16 mm， the length of the left main branch was 20.59±6.38 mm， and the length of the right main branch was 21.99±7.98 mm. Compared with the control group， the device group had significantly shorter hepatic pedicle handling time （14.10±1.30 minutes vs 17.50±2.00 minutes， t=-5.620， P=0.001） and time of operation （217.00±28.28 minutes vs 241.87±19.49 minutes， t=-2.804， P=0.009）. The device group had a significantly lower incidence rate of bile duct injury than the control group （0 vs 20%， P=0.031）. Conclusion3D reconstruction based on the Laennec’s capsule can accurately display the anatomical variations of the hepatic pedicle. The extra-sheath hepatic pedicle dissection/occlusion clamp developed based on such data can optimize the process of hepatic pedicle management and improve surgical safety， and therefore， it holds promise for clinical application.

Recent studies have identified a missense mutation in the β1-receptor (ADRB1-A187V) that exerts a pronounced impact on human sleep, with a noted decrease in protein abundance in vivo. The administration of β-blockers is frequently associated with sleep disturbances in clinical settings. In this study, we assessed the influence of various β-blockers on sleep within mouse models. Our findings indicated that β-blockers could induce varying degrees of arousal, sleep disruption, and a decrease in REMS (rapid eye movement sleep). We examined the dose-dependent effects of metoprolol and nebivolol on both sleep and cardiac functionality in both wild-type and Adrb1-A187V mutant mice. Our data suggested that, in contrast to cardiac effects, higher doses of metoprolol are required to have noted impact on sleep. No genotype effect was observed with metoprolol in terms of sleep or cardiac function. In contrast, the mutant mice demonstrated increased sensitivity to nebivolol, which exacerbated sleep fragmentation and impeded the onset of REMS. This study is expected to provide some reference for minimizing the occurrence of sleep disorders and reducing the adverse reactions of drugs to the greatest extent.

Objective:To explore the clinical features, genetic traits and prognosis status of acute myeloid leukemia (AML) patients with TP53 mutation.Methods:A retrospective case series study was performed. Clinical data of 42 AML patients with TP53 mutation abundance of at least 10% who were admitted to the First Hospital of Jilin University from April 2018 to August 2023 were collected. Chromosomal karyotypes were detected using fluorescence in situ hybridization (FISH), and next-generation sequencing (NGS) was performed on bone marrow samples from these patients. The Kaplan-Meier method was utilized to analyze the recurrence-free survival (RFS) of 22 patients who achieved complete remission (CR) after induction therapy, as well as the overall survival (OS) of 39 patients who underwent treatment. The Cox proportional hazards model was employed to analyze the factors influencing RFS and OS. Thirty-one patients who underwent induction therapy for ≥ 2 courses were divided into the non-refractory group (22 cases) and the refractory group (9 cases) based on whether CR was achieved after induction therapy, and the clinical and genetic characteristics and prognosis of the two groups were compared.Results:Among the 42 AML patients with TP53 mutation, there were 26 males and 16 females, with a median age [ M( Q1, Q3)] of 57.0 (44.0, 63.5) years. At the initial stage, the median white blood cell count in peripheral blood was 4.06×10 9/L (2.59×10 9/L, 27.36×10 9/L), the median proportion of bone marrow primitive cells was 45.25% (29.00%, 80.63%), the proportion of primitive and immature cells in bone marrow cell immune analysis was 28.70% (12.71%, 61.48%), and the median TP53 mutation abundance was 55.48% (38.72%, 73.31%). Among the 42 patients, 23 cases (54.76%) had complex chromosomal karyotypes, with the most frequent abnormal chromosomes being chromosome 5 (47.62%, 20 cases), chromosome 7 (45.24%, 19 cases) and chromosome 17 (26.19%, 10 cases). The mutant genes with high mutation frequency were DNMT3A (19.05%, 8 cases), N/KRAS (19.05%, 8 cases), ASXL1 (16.67%, 7 cases) and NPM1 (16.67%, 7 cases). Among the 39 patients with detailed TP53 mutation data, 36 had missense mutations and 3 had frameshift mutations. In the non-refractory and refractory groups, the N/KRAS mutation rates were 13.6% (3/22) and 55.6% (5/9), respectively ( P = 0.027). The median RFS time of 22 CR patients after induction therapy was 109 d (95% CI: 57-483 d). The results of multivariate Cox regression analysis showed that complex chromosomal karyotype was an independent risk factor for RFS ( HR = 11.819, 95% CI: 1.345-103.880, P = 0.028). The median RFS time of patients without and with complex chromosomal karyotypes was 842 d (95% CI: 0-1 716 d) and 148 d (95% CI: 88-208 d), respectively, and the difference in RFS between the two groups was statistically significant ( P = 0.001). The median OS time of 39 patients receiving treatment was 151 d (95% CI: 75-227 d). The results of multivariate Cox regression analysis showed that NPM1 gene mutation was an independent protective factor for OS ( HR = 0.289, 95% CI: 0.075-1.114, P = 0.071). The median OS time of patients with and without NPM1 gene mutation was 1 562 d (95% CI: 610- 1 710 d) and 136 d (95% CI: 99-173 d), respectively, and the difference in OS between the two groups was statistically significant ( P = 0.020). Conclusions:TP53-mutant AML patients often have poor chromosomal karyotypes and genetic abnormalities, while refractory AML patients often have N/KRAS mutation. The complex chromosomal karyotype is a risk factor for RFS, while NPM1 gene mutation is a protective factor for OS.

Objective To systematically evaluate the influencing factors for antiretroviral therapy(ART)discontinuation in Chinese human immunodeficiency virus(HIV)/acquired immuno deficiency syn-drome(AIDS)patients.Methods A computer-based search was conducted in PubMed,Web of Science,Em-base,The Cochrane Library,CNKI,Wanfang,VIP,and China Biology Medicine(CBM)databases for studies on influencing factors of ART discontinuation in Chinese HIV/AIDS patients from the establishment of the databases to August 2024.Meta-analysis was performed on the included studies by using Stata16.0.Results A total of 17 studies were included.Meta-analysis showed that the following factors were associated with ART discontinuation:male gender(OR=1.301,95%CI:1.099-1.540),age≥50 years(OR=1.212,95%CI:1.109-1.324),unmarried/divorced/widowed marital status(OR=1.198,95%CI:1.060-1.354),education level was or below senior high school(OR=1.778,95%CI:1.508-2.096),infection route was in-travenous drug use(OR=2.420,95%CI:1.989-2.945),baseline CD4 cell count>500 cells/μL(OR=1.157,95%CI:1.020-1.313),tuberculosis co-infection before ART(OR=1.559,95%CI:1.398-1.739),hepatitis B co-infection before ART(OR=1.554,95%CI:1.305-1.851),AIDS-related symptoms occur be-fore ART(OR=1.245,95%CI:1.148-1.351),time from diagnosis to treatment initiation≥365 days(OR=1.449,95%CI:1.301-1.615),initial treatment regimen containing zidovudine(OR=1.573,95%CI:1.206-2.052),treatment at county-level or lower institutions(OR=1.204,95%CI:1.153-1.257),exist drug adverse reactions(OR=7.043,95%CI:3.142-15.786),and compliance education(OR=0.182,95%CI:0.094-0.352).Conclusion There are multiple factors influencing ART discontinuation in Chinese HIV/AIDS patients.Early identification of individuals at risk of discontinuation and targeted interventions are nec-essary to promote their maintenance of ART.

Objective　To analyze and study the status quo and deficiencies in the construction of talent teams at all levels of CDCs in Hainan Province and put forward countermeasures to provide a reference basis for the high-quality development of talent team construction in all levels of CDCs in Hainan Province. Methods Using field surveys and data retrieval, spatial analysis was employed to compare the overall differences in human resource status of the provincial-level CDC and CDCs in five regional areas (East, West, South, North, and Central Hainan). The coordination between human resource allocation and development strategies was analyzed. A descriptive analysis mainly utilized CDC survey questionnaires and other research forms to explore the health human resources of the province's CDCs. Results The professional and technical personnel in the provincial CDCs comprise 1 431 individuals, accounting for 82.3% (1 431/1 739) of the total number of actual employees, which falls short of the Central Institutional Reform Commission's (CIRC) mandate that technical professionals comprise at least 85% of the total workforce (CIRC Document [2014] No. 2). Among Hainan's CDC personnel, 115 individuals are recognized as high-level talents within the Hainan Free Trade Port framework. These include one Class C talent, 22 Class D talents, and 93 Class E talents. Class A, B, and C-level talents are deficient. The majority of staff at both the provincial and regional CDCs hold bachelor's degrees. There is a significant proportion of staff with associate degrees or lower qualifications, coupled with a severe shortage of highly educated personnel. Postgraduates with master’s degrees or above account for 27.8% (65/233) in the provincial CDC, indicating low educational credentials among personnel in Hainan's CDCs. The central region, characterized by slower economic and social development, faces greater challenges in attracting and retaining high-level talent. There is a scarcity of public health professionals with interdisciplinary expertise. Some public health staff lack clinical knowledge, experience, and skills in disease treatment. Furthermore, there is a need to strengthen on-site emergency response capabilities for public health emergencies. The structural ratio of senior, intermediate, and junior professional and technical positions in the provincial CDC is 40%∶45%∶15%. The position settings are limited to ranking levels without distinction by professional category, leading to a bottleneck-type competition like crossing the "one log bridge" for technical position promotions. Conclusion　Hainan Province faces significant challenges in developing its public health workforce, both in technical expertise and management capacity. Especially under the context of the closure operation of the Hainan Free Trade Port, it is necessary to continuously strengthen top-level talent design to cultivate a favorable policy, system, and cultural environment, thereby promoting the sustained and healthy development of the province's public health career.
