Objective:To analyze the correlation between 24-hour urinary sodium excretion and early renal function impairment in patients with primary hypertension.Methods:This cross-sectional study included patients with primary hypertension who were admitted to the Department of Cardiology of the Chinese People′s Liberation Army General Hospital between January 2021 and October 2024. Patients were divided into low-sodium, medium-sodium, and high-sodium groups based on their 24-hour urinary sodium excretion. General clinical data were collected using the electronic medical record system. Urinary sodium, protein, and microalbumin excretion were analyzed from 24-hour urine samples. Spearman correlation analysis was used to explore the relationship between 24-hour urinary sodium excretion and urinary microalbumin excretion. A multiple linear regression model was used to further assess the independent association between these variables. Subgroup analyses were conducted based on age were performed to determine whether age influenced the relationship between urinary sodium excretion and renal function impairment.Results:A total of 1 065 patients with primary hypertension were included, with a mean age of (55.26±14.06) years, including 568(53.33%) males. The low-sodium, medium-sodium, and high-sodium groups included 223, 579, and 263 patients, respectively. The 24-hour urinary microalbumin excretion in the high-sodium group was significantly higher than in the medium-sodium and low-sodium groups, and this trend remained consistent across different age groups (all P<0.05). Spearman correlation analysis showed a positive correlation between 24-hour urinary sodium excretion and urinary microalbumin excretion ( r=0.220, P<0.001), and this relationship was observed in all age groups (all P<0.05). Multiple linear regression analysis confirmed an independent association between 24-hour urinary sodium excretion and urinary microalbumin excretion (all P<0.001), which persisted across different age groups (all P<0.05). Conclusion:In patients with primary hypertension, 24-hour urinary sodium excretion is closely associated with microalbumin excretion, suggesting a potential link to early renal function impairment.

Objective:To explore the current implementation status and challenges of family doctor contract services (FDCS) from the perspective of contracted residents.Methods:This qualitative study used purposive sampling to select contracted residents from 11 primary healthcare institutions across five cities in China. Semi-structured interviews were conducted from March to December 2024, covering topics such as awareness of contracting, service experience, health needs, service continuity, and policy recommendations. Thematic framework analysis was applied to organize, code, and summarize the data.Results:A total of 25 contracted residents were interviewed (6 men, 19 women; 11 from central urban areas, 14 from suburban or rural towns; 8 with chronic diseases). Three main themes and ten sub-themes emerged: Theme Ⅰ: Pathways to improved service accessibility (optimized chronic disease management, more efficient referrals, and improved health education). Theme Ⅱ: Structural misalignment between supply and demand (limited specialty services despite patient needs, insufficient coverage and public awareness of home-based medical care, imbalanced human resources, and service disruption due to clinician turnover). Theme Ⅲ: Challenges in service awareness and communication mechanisms (information asymmetry and public misperception regarding FDCS, perverse incentives in administrative performance evaluation, and communication barriers in building patient-doctor trust).Conclusions:While FDCS has shown progress in chronic disease management, referral coordination, and health education, structural supply-demand gaps and communication challenges continue to hinder service quality. Improvements in resource allocation and service models are needed to support high-quality development.

OBJECTIVE:
In Pakistan, traditional medicines are an important component of the medical system, with numerous varieties and great demands. However, due to the scattered resources and the lack of systematic collection and collation, adulteration of traditional Pakistani medicine (TPM) is common, which severely affects the safety of their medicinal use and the import and export trades. Therefore, it is urgent to systematically organize and unify the management of TPM and establish a set of standards and operable methods for the identification of TPM.
METHODS:
We collected and organized the information on 128 TPMs with regard to their medicinal parts, efficacy, usage, and genetic material, based on Pakistan Hamdard Pharmacopoeia of Eastern Medicine: Pharmaceutical Codex. The genetic information of TPM is summarized from national center for biotechnology information (NCBI) and global pharmacopoeia genome database (GPGD). Furthermore, we utilized bioinformatics technology to supplement the chloroplast genome (cp-genome) data of 12 TPMs. To build the web server, we used the Linux + Apache + MySQL + PHP (LAMP) system and constructed the webpage on a PHP: Hypertext Preprocessor (PHP) model view controller (MVC) framework.
RESULTS:
We constructed a new genomic database, the traditional Pakistani medicine genomic database (TPMGD). This database comprises five entries, namely homepage, medicinal species, species identification, basic local alignment search tool (BLAST), and download. Currently, TPMGD contains basic profiles of 128 TPMs and genetic information of 102 TPMs, including 140 cytochrome c oxidase subunit I (COI) sequences and 119 mitochondrial genome sequences from Bombyx mori, 1 396 internal transcribed spacer 2 (ITS2) sequences and 1 074 intergenic region (psbA-trnH) sequences specific to 92 and 83 plant species, respectively. Additionally, TPMGD includes 199 cp-genome sequences of 82 TPMs.
CONCLUSION
TPMGD is a multifunctional database that integrates species description, functional information inquiry, genetic information storage, molecular identification of TPM, etc. The database not only provides convenience for TPM information queries but also establishes the scientific basis for the medication safety, species identification, and resource protection of TPM.

The structure of intestinal tissue is complex. In vitro simulation of intestinal structure and function is important for studying intestinal development and diseases. Recently, organoids have been successfully constructed and they have come to play an important role in biomedical research. Organoids are miniaturized three-dimensional (3D) organs, derived from stem cells, which mimic the structure, cell types, and physiological functions of an organ, making them robust models for biomedical research. Intestinal organoids are 3D micro-organs derived from intestinal stem cells or pluripotent stem cells that can successfully simulate the complex structure and function of the intestine, thereby providing a valuable platform for intestinal development and disease research. In this article, we review the latest progress in the construction and application of intestinal organoids.

Cancer is a serious global health problem and a major cause of human death. Conventional cancer treatments often run the risk of impairing vital organ functions. Anticancer peptides (ACPs) are considered to be one of the most promising therapeutic agents against common human cancers due to their small sizes, high specificity, and low toxicity. Since ACP recognition is highly limited to the laboratory, expensive, and time-consuming, we proposed pLM4ACP, a model for predicting ACPs based on machine learning and protein language models. In this model, the protein language model ProtT5 was used to extract the features of ACPs, and the extracted features were input into the support vector machine (SVM) classification algorithm for optimization and performance evaluation. The model showcased significantly higher accuracy than other methods, with the overall accuracy of 0.763, F1-score of 0.767, Matthews correlation coefficient of 0.527, and area under the curve of 0.827 on the independent test set. This study constructs an efficient anticancer peptide prediction model based on protein language models, further advancing the application of artificial intelligence in the biomedical field and promoting the development of precision medicine and computational biology.

Objective To explore the short and long term efficacy of ultrasound therapy combined with muscle imbalance adjustment training in patients with adhesive capsulitis(AC) ofthe shoulder. Methods A total of 60 AC patients were divided into an observation group and a control group,both each consisting of 30 cases. The observation group underwentultrasound therapy along with muscle imbalance adjustment training,while the control group received acupuncture treatment,both for a duration of 20 days. The Visual Analogue Scale(VAS),goniom-eter for ROM,Manual Muscle Testing(MMT),Constant-Murley Shoulder Score,and modified Barthel index were used to access shoulder jointpain level,range of motion (ROM),peripheral muscle strength,shoulder joint func-tion,and daily living abilities,respectively. The Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) were utilized to evaluate the levels of anxiety and depression.All the assessments were conducted and compared between the two groups before treatment,at the end of treatment,and at 6 and 12 months after treatment. Results Both groups showed varying degrees of improvement in ROM,MMT,VAS,Constant-Murley score,modified Barthel index,and emotional status compared to pre-treatment. The observation group demonstrated superior outcomes in posterior shoulder extension strength,VAS,Constant-Murley score,modified Barthel index,HAMA,and HAMD scores at the end of treatment (P<0.05). At 6 months post-treatment,the observation group showed better shoulder joint flexion,extension,abduction,and adduction ROM,as well as muscle strength in flexion,external rotation,and internal rotation,VAS,Constant-Murley score,modified Barthel index,HAMA,and HAMD scores. At 12 months after treatment,the observation group continued to show superior outcomes in all the aforementioned indexes (P<0.05). Conclusion The combination of ultrasound therapy and muscle imbalance adjustment training can effectively reduce shoulder joint pain,improve ROM,enhance muscle strength around the shoulder joint,improve shoulder joint function,alleviate anxiety and depression,and ultimately enhance the quality of life for patients with AC.
