Objective: To investigate the distribution characteristics of ABO and Rh blood group antigen phenotypes among blood donors in the Yantai, Shandong. Methods: Blood samples from 310 180 voluntary blood donors in Yantai collected from January 2019 to December 2023 were tested for ABO and Rh blood group antigens using standard serological methods. RhD-negative samples were further typed for C, c, E, and e antigens. Population genetic analysis of blood groups was performed: allele frequencies were inferred from ABO phenotypes, and Rh allele/haplotype frequencies were estimated based on the proportion of RhD-negative donors and CcEe antigen typing, followed by Hardy-Weinberg equilibrium testing. Results: The phenotypic distribution frequency of ABO blood groups was B(32.72%)>O(28.93%)>A(27.65%)>AB(10.70%). The inferred allele frequencies were r(53.74%)>q(24.78%)>p(21.48%), consistent with Hardy-Weinberg equilibrium (P>0.05). A total of 1 872 Rh-negative donors (0.603%) were identified. The most common Rh phenotypes were ccdee (59.56%) and Ccdee (30.18%). The distribution of Rh antigen phenotypes deviated significantly from Hardy-Weinberg equilibrium (χ
=37.15, P<0.001), with the cde haplotype showing the highest frequency. There was no statistically significant difference in ABO blood group distribution between RhD-positive and RhD-negative donors (P>0.05). Conclusion: The ABO blood group distribution among voluntary blood donors in Yantai is generally stable and consistent with population genetic equilibrium, whereas the Rh antigen phenotype distribution deviates from equilibrium, indicating potential underlying genetic structural differences.

Despite breakthroughs in immunotherapy for solid tumors, significant variations in treatment efficacy persist. Up to 80% of cancer patients suffer from malnutrition, which leads to: lymphoid atrophy and reduced T-cell reserves; deficiency of substrates required for T-cell activation and expansion; concurrent inflammation hindering T-cell infiltration into tumors; and cachexia accelerating PD-1 antibody clearance. Clinical studies confirm that severe malnutrition significantly impairs immune responses and increases the risk of treatment toxicity. Therefore, implementing standardized nutritional therapy is crucial for optimizing the reserve, activation, expansion, and infiltration capacity of immune cells, thereby providing a sound immune system foundation for immunotherapy. Immunonutrition therapy, by enhancing immunonutrients such as arginine, omega-3 polyunsaturated fatty acids, and nucleotides, reduces the secretion of pro-inflammatory mediators and promotes T-cell activation and proliferation. This enhances anti-tumor immune responses, prolongs survival, and advances cancer treatment towards multimodal combination and precision approaches.

Objective To explore the risk factors of painful diabetic neuropathy (PDN) in patients with type 2 diabetes mellitus (T2DM). Methods A total of 269 patients with type 2 diabetes mellitus (T2DM) who were treated in the Department of Endocrinology at Zhangjiagang Hospital Affiliated to Soochow University from January 2020 to December 2024 were selected. The patients were divided into two groups: T2DM without PDN (n=190) and T2DM with PDN (n=79). The general characteristics and biochemical indicators of the two groups of patients were compared. Multivariate logistic regression was used to analyze the associated factors with PDN in T2DM. The receiver operating characteristic (ROC) curve was used to evaluate fasting C-peptide (FC-P), body mass index (BMI), and disease duration to predict the risk of PDN. Results Compared with the T2DM group without concurrent PDN, the T2DM group with concurrent PDN had a longer disease course, lower BMI, higher HDL-C, lower FC-P, and a higher proportion of diabetic retinopathy. The differences between the two groups were statistically significant (P<0.05). The results of multivariate logistic regression analysis showed that BMI, duration, and FC-P were associated factors of PDN. Conclusion BMI, duration and FC-P are associated factors of painful neuropathy complicated with type 2 diabetes.

Bovine piroplasmosis, caused by infections with genus of Babesia and Theileria, is a tick-borne hemoparasitic disease. Recovered cattle often become asymptomatic persistent carriers, which represent potential sources of infection, and the pathogens of some forms of bovine piroplasmosis have zoonotic potential, which greatly threatens the public health security. Currently, the etiological diagnostic approaches of bovine piroplasmosis mainly include microscopy of blood smears, PCR assay, fluorescent quantitative real-time PCR assay, and loop-mediated isothermal amplification, and serological assay mainly includes indirect fluorescent antibody assay, enzyme-linked immunosorbent assay and immunochromatographic assay. This article systematically reviews the advances in the application of etiological approaches and serological assay for diagnosis of bovine piroplasmosis, and proposes future directions in the development of bovine piroplasmosis diagnosis, so as to provide insights into effective surveillance and precision control of bovine piroplasmosis in China.

ObjectiveTo systematically retrieve, analyze, and summarize the basic information and clinical research evidence of Chinese patent medicines (CPMs) for endometriosis via a scoping review method. MethodsCPMs indicated for EM were identified from three major drug lists, CNKI, clinical guidelines, and textbooks. Relevant clinical studies were retrieved from eight Chinese and English databases from inception to April 1, 2025. Key data from included studies were extracted to analyze characteristics of CPMs and their clinical evidence. ResultsA total of 18 CPMs were included, among which those with blood-activating and stasis-resolving effects accounted for the highest proportion. Constituent herbs predominantly exhibited sweet, bitter, and pungent flavors, with tropism to the liver and spleen meridians. Daily treatment costs varied substantially across CPMs. The 438 included studies involved 13 CPMs, among which Guizhi Fuling capsules/pills, Sanjie Zhentong capsules, and Dan'e Fukang soft extract/granules were the most extensively studied. Randomized controlled trials (RCTs) were the predominant study design. The most common comparison was between CPMs combined with Western medicine and Western medicine alone. The largest number of studies reported a sample size of 51-100 cases. The high-frequency outcome indicators covered 10 domains, including clinical response rate, adverse reactions, female hormone levels, serum CA125 levels, and recurrence status. ConclusionMultiple oral CPMs demonstrate efficacy in EM management, yet inadequate safety profiles persist in drug labeling. The annual number of clinical studies on oral CPMs for endometriosis showed an overall increasing trend. However, clinical research has shortcomings including uneven distribution of CPMs, small sample sizes, and suboptimal methodological rigor. Future efforts should focus on updating drug indications and safety information in package inserts, conducting high-quality clinical research, and generating more robust evidence to support the clinical use of oral CPMs for EM.

ObjectiveTo enhance the genetic diagnostic yield for fetal short femur length (FL) and to evaluate the integration of whole exome sequencing (WES) with chromosomal abnormality detection in prenatal diagnosis. MethodsA total of 27 mid-to-late trimester fetuses diagnosed with short FL [FL < 5th percentile for gestational age or < -2 SD (Standard Deviation)] at the Prenatal Diagnosis And Medical Genetics Center,Shenshan Medical Center,Memorial Hospital of Sun Yat-Sen University between November 2023 and May 2025 were included. Amniotic fluid or umbilical cord blood samples were collected and subjected to chromosomal karyotyping (19cases), chromosomal microarray analysis (CMA) or low-coverage whole genome copy number variation(CNV-Seq) (27 cases), and trio-based whole exome sequencing (trio-WES) (27 cases). The pathogenicity of genetic variants were interpreted according to the American College of Medical Genetics and Genomics (ACMG) guidelines. ResultsTwenty-six genomic variants were detected in 17 of the 26 fetuses, including numerical chromosomal abnormalities (mosaic type), copy number variations (CNVs), single nucleotide variants (SNVs) and insertions-deletions (INDELs). Genomic variants detected in 11 cases could explain the short femur phenotype.The overall diagnostic rate was 11/27, with pathogenic/likely pathogenic variants explaining 9 cases and variants of uncertain significance (VUS) accounting for 1 cases. In addition Chromosomal karyotype analysis revealed chromosome mosaicism explaining 1 case. The diagnostic rate of CNV detection (CMA/CNV-seq) was 2/27, while WES achieved a diagnostic rate of 10/27, with an incremental yield of 8/27 in cases with negative or inconclusive CNV results. Pathogenic mutations involved genes such as FGFR3, SHOX, DUOX2, CLCN5, and HBA1/HBA2. ConclusionTrio-WES significantly improves the genetic diagnostic rate for fetal short femur length, particularly in cases where chromosomal analysis fails to identify a cause. Karyotyping remains valuable for detecting low-level mosaicism in large-scale chromosomal abnormalities, thereby complementing WES and CNV detection. A stepwise or parallel genetic testing strategy is recommended in prenatal diagnosis to optimize diagnostic efficiency and support clinical decision-making.

ObjectiveTo explore the effect of Yishen Tongluo prescription on sperm DNA fragmentation index (DFI) and sperm mitochondrial membrane potential (MMP) in patients with asymptomatic idiopathic asthenospermia infertility. MethodsA total of 128 patients with asymptomatic idiopathic asthenospermia were randomly assigned to an experimental group (64 cases) and a control group (64 cases). The experimental group received Yishen Tongluo prescription, while the control group was treated with Wuzi Yanzongwan combined with L-carnitine oral solution. One treatment course lasted 12 weeks. Spouse pregnancy rate, sperm progressive motility (PR), total sperm motility (PR+NP), sperm function (sperm tail hypotonic swelling rate, sperm acrosin activity), sperm DFI, and sperm MMP were compared between the two groups before and after treatment. Adverse reactions were observed and recorded during the study, and clinical efficacy and safety were systematically evaluated. ResultsA total of 121 patients completed the study, including 61 in the experimental group and 60 in the control group. The spouse pregnancy rate in the experimental group was 14.75% (9/61), higher than that in the control group at 6.67% (4/60), though the difference was not statistically significant. Clinical efficacy in the experimental group was superior to that in the control group (P<0.05). Compared with the results before treatment, sperm PR, PR + NP, sperm tail hypotonic swelling rate, sperm acrosin activity, sperm DFI, and sperm MMP were significantly improved in both groups after treatment (P<0.05), with greater improvements in the experimental group (P<0.05). However, there was no significant change in sperm concentration in either group after treatment. During the study, no abnormal safety indicators or significant adverse reactions occurred in either group. ConclusionThe kidney-tonifying and collateral-dredging method shows good clinical efficacy in the treatment of asymptomatic idiopathic asthenospermia infertility. Yishen Tongluo prescription can improve sperm motility, increase spouse pregnancy rate, enhance sperm function, and demonstrates good safety. Its mechanism may be related to reducing sperm DFI and increasing sperm MMP.

OBJECTIVE To construct ensemble learning models for predicting high-use days of budesonide based on meteorological factors, thereby providing reference for hospital pharmacy management. METHODS Meteorological data for 2024 and outpatient budesonide usage data from the jurisdiction of Sanming Hospital of Integrated Traditional Chinese and Western Medicine were collected. High-use days were defined as the 75th percentile of outpatient budesonide usage, and a corresponding dataset was established. The prediction task was formulated as a classification problem, and three ensemble learning models were developed: Random Forest, Extreme Gradient Boosting (XGBoost), and Histogram-based Gradient Boosting Classifier. Model performance was evaluated using accuracy, precision, recall, F1-score, and log-loss. Model interpretability was analyzed using Shapley Additive Explanations (SHAP). RESULTS The Histogram-based Gradient Boosting Classifier achieved the best performance (accuracy=0.75, F1-score=0.48), followed by XGBoost (accuracy=0.74, F1-score=0.43) and Random Forest (accuracy=0.72, F1-score=0.22). SHAP results suggested that the prediction results of the last two models have the highest correction. CONCLUSIONS Ensemble learning models can effectively predict high-use days of budesonide, with the Histogram- based Gradient Boosting Classifier demonstrating the best predictive performance. Low temperature, high humidity, and low atmospheric pressure show significant positive impacts on the prediction of daily budesonide usage.

Objective:
To explore the influencing factors for implementation of weight management services in primary medical and healthcare institutions, so as to provide references for implementing sustainable services of weight management.
Methods:
From May to June 2025, Pinghu City, Zhejiang Province was selected as the survey site. Personnel responsible for weight management in primary medical and healthcare institutions were selected as the survey subjects using a combined method of purposive sampling and snowball sampling. Based on the five core domains of the consolidated framework for implementation research (CFIR), a semi-structured interview outline for weight management services in primary medical and healthcare institutions was designed. Original data was collected through face-to-face semi-structured interviews. Interview data was organized and analyzed using framework analysis. Factors affecting weight management services were quantitatively analyzed by referencing CFIR's structural rating criteria.
Results:
A total of 21 participants completed interviews, covering positions in nutrition, endocrinology, traditional Chinese medicine, general practice, maternal health, and public health. There were 9 males and 12 females. Fifteen participants (71.43%) were aged 35 years and above, 18 (85.71%) held a bachelor's degree or higher, and 15 (71.43%) were frontline medical staff. Fifteen factors affecting weight management services were identified across five domains: innovation, outer setting, inner setting, individuals, and implementation process. Six barrier factors were identified: difficulties in policy implementation, time-consuming interventions, limited incentive measures, lack of professional skills, unclear weight-loss plans and goal setting, and imperfect follow-up and evaluation mechanisms. Three neutral factors were identified: the development and refinement of policies and regulations, the implementation of weight management training, and the optimization of the referral process within integrated healthcare systems (medical alliances / communities). Six facilitating factors were identified: the relatively significant advantages of lifestyle interventions, collaboration and coordination across multiple departments, cooperative communication among different units within the institution, the inherent convenience of primary care settings, a strong sense of professional responsibility, and the establishment of multidisciplinary teams.
Conclusions
The delivery of weight management services in primary medical and healthcare institutions is influenced by a wide array of factors across multiple domains. It requires policy support, multi-department coordination, a practice-oriented training system, optimized team resource allocation, incentives, and improved professional skills of medical staff to jointly promote long-term implementation.
