This study focuses on the core pathology of sinew wei (痿), which is mainly characterized by the fai-lure of qi and blood to nourish the sinews. A mechanical-biological response framework is constructed with mitochondria as a key component, explaining the modern interpretation of the disease location of sinew transmitting to qi and blood pathology. Mechanical loading, as a physical stress stimulus applied to the body, manifests primarily as passive loading formed by external forces such as massage, and active loading resulting from voluntary muscle contractions, such as dao yin (导引). Mechanical loading can regulate mitochondrial function through two pathways, mechanical signal transduction and metabolic demand-driven regulation. Skeletal muscle mitochondrial dysfunction is regarded as the core microscopic basis of qi imbalance in sinew wei, highlighting the intrinsic connection between qi and mitochondrial energy metabolism, as well as between blood and microcirculatory efficiency. Accordingly, distinct regulatory patterns of mechanical loading are identified. Wei associated with qi stagnation may correspond to mitochondrial network fragmentation and can be treated by regulating qi through passive loading, such as tuina, to restore mitochondrial dynamics. In contrast, wei caused by qi deficiency is attributed to insufficient mitochondrial biogenesis and may be treated by tonifying qi through active loading, such as dao yin, to promote mitochondrial biogenesis. This framework reveals the biological differences in mitochondrial regulation induced by distinct mechanical loading modalities and provides a microscopic mechanism-based explanation for the principle of "treating the same disease with different methods" in sinew wei.

OBJECTIVE To provide a reference for anticoagulation therapy, adverse drug reaction monitoring, and individualized medication adjustment in complex cases, such as those with thrombocytopenia following bioprosthetic heart valve replacement. METHODS Clinical pharmacists participated in the pharmaceutical care of a patient with thrombocytopenia following bioprosthetic heart valve replacement. For cardiac insufficiency, the pharmacists recommended maintaining oral bisoprolol, sacubitril/valsartan, spironolactone, furosemide, and potassium chloride, with levosimendan added to enhance myocardial contractility, while monitoring blood pressure, heart rate and serum potassium levels. For thrombocytopenia, based on literature- based risk assessment, the pharmacists advised administering recombinant human interleukin-11 (rhIL-11), platelet transfusion, and employing anticoagulation therapy with nadroparin calcium bridging to warfarin, with warfarin dosage adjusted according to the international normalized ratio (INR). For rapid ventricular rate atrial fibrillation, amiodarone and digoxin were recommended. For acute liver injury, suspected to be induced by amiodarone and rhIL-11, the pharmacists suggested discontinuing the relevant drugs and treating with ademetionine 1,4-butanedisulfonate combined with polyene phosphatidylcholine for liver protection treatment. The patient received anticoagulation medication education emphasizing strict INR monitoring and close observation for bleeding or thrombotic events. RESULTS The clinicians adopted these recommendations. Following the intervention, the patient’s liver function showed significant improvement, with alanine aminotransferase decreasing to 70 U/L and aspartate aminotransferase to 42 U/L. The ventricular rate stabilized at 70-100 beats per minute, cardiac function remained stable, the INR was maintained within the target range of 1.80-2.50, and the patient was ultimately discharged with improved condition. CONCLUSIONS Through balancing anticoagulation and bleeding risks, the clinical pharmacists applied pharmaceutical expertise to assist in developing personalized anticoagulation regimens, conducted adverse drug reaction monitoring and evaluation, and optimized medication strategies, thereby effectively ensuring patient safety and therapeutic efficacy.

Lung cancer is the leading cause of cancer-related deaths worldwide, and tumor metastasis is a key factor contributing to the mortality of most lung cancer patients. Aberrant activation of epithelial-mesenchymal transition (EMT) is a major driver of lung cancer progression and metastasis. EMT is characterized by the loss of apical-basal polarity and intercellular adhesion in highly differentiated, polarized, and organized epithelial cells, which acquire motility, migratory potential, and invasive properties. During this process, cells undergo cytoskeletal remodeling and transform into a mesenchymal phenotype, accompanied by associated changes in cellular markers. The EMT process is highly complex and is tightly regulated by intricate networks involving multiple transcription factors, post-translational controls, epigenetic modifications, and non-coding RNAs. Therefore, therapies targeting the mechanisms of malignant transformation and their associated pathways in lung cancer are of significant clinical importance. In recent years, EMT has attracted increasing attention as a potential target for cancer therapy. Chinese medicine, with its characteristics of multi-target action, low side effects, and good therapeutic efficacy, has demonstrated an important role in anticancer treatment. A series of studies have investigated the role of Chinese medicine in inhibiting EMT in lung cancer. Active ingredients of Chinese medicine, including flavonoids, glycosides, phenols, terpenoids, saccharides, and alkaloids, as well as Chinese medicine compound formulas, have shown significant regulatory effects on EMT. Their mechanisms mainly involve multiple pathways, targets, and links, including signaling pathways, exosomes, microRNAs (miRNAs), and the tumor-associated immune microenvironment. This article summarizes the mechanisms by which EMT promotes malignant tumor progression and reviews the current research on how Chinese medicine active ingredients, monomers, and compound formulas inhibit EMT and suppress lung cancer cell migration and invasion. This study is expected to provide comprehensive theoretical information for basic and translational research on lung cancer.

This study aims to describe the population and regional distribution characteristics of smoking behavior among adult twins in the China Twin Registry (CNTR), as well as the concordance rates for smoking behavior in monozygotic and dizygotic twins, and estimate the heritability. The study population included adult twins in CNTR who had smoking questionnaire data. A random-effects regression model was used to describe the distribution of smoking behavior among different subgroups based on various characteristics. The concordance of smoking behavior between different zygosity groups was calculated, and heritability was estimated. A total of 28 444 twin pairs were included in this study, with an average age of (36.6±12.0) years. Among male twins, 41.2% were current smokers, while only 1.2% of females smoked. Higher smoking rates were observed among male smokers in the 50-59 age group ( z=23.0, P<0.001), northern regions ( z=2.9, P<0.01), rural areas ( z=-5.2, P<0.001), those who were divorced/widowed ( z=3.8, P<0.001), and first-born twins ( z=-4.3, P<0.001), while lower smoking rates were found in those with higher education ( z=-16.1, P<0.001) and unmarried individuals ( z=-16.0, P<0.001). The smoking concordance rate for male monozygotic twins was 69.6%, significantly higher than the 57.3% concordance rate for dizygotic twins ( χ 2=105.0, P<0.05). The heritability of smoking behavior in male twins was estimated at 28.9% (95% CI: 24.3%-33.4%). Stratified analyses showed differences in heritability across regions and age groups: the heritability in northern regions was 32.6% (95% CI: 27.3%-38.0%), higher than the 21.0% (95% CI: 12.4%-29.5%) observed in southern regions; the highest heritability of 35.1% (95% CI: 26.3%-43.9%) was found in the 18-29 age group, with heritability decreasing with age. In conclusion, the smoking rate and influencing factors in the twin population are similar to those in the general population, with unique characteristics, such as higher smoking rates in first-born twins. Genetic factors have a significant impact on smoking behavior.

Whole-genome sequencing, serotype typing, MLST typing, population genetic structure analysis, and core-genome single nucleotide polymorphism (cgSNP) analysis were performed on 23 strains of mucoid Haemophilus influenzae collected from the Laboratory Center of Hunan Children′s Hospital from January 2021 to December 2022. Drug susceptibility tests were conducted using the automated microbial identification and susceptibility analysis system AF-600, and virulence genes and drug resistance genes were analyzed based on the whole-genome sequences. Based on the serotype typing of whole-genome sequencing, all 23 strains were Haemophilus influenzae type b (Hib). MLST analysis revealed that the 23 strains belonged to six ST types, among which 10 strains (43.5%) were ST386, 5 strains (21.7%) were ST18, and 2 strains (8.7%) were the newly discovered ST2887. Bayesian population structure analysis (BAPS) showed three distinct populations. The results of the virulence gene analysis showed that the carriage rates of genes encoding capsule-related proteins and those associated with bacterial immune regulation and inflammatory signaling pathways were all 100%. However, the ompP5 gene related to bacterial adhesion, and the hgpC and hxuA genes related to bacterial protein metabolism were all present in the newly discovered ST2887. The in vitro drug susceptibility test results of 23 strains of mucoid Hib showed that the resistance rates to ampicillin, cefuroxime, and Trimethoprim-sulfamethoxazole were 13.0%(3 strains), 13.0%(3 strains), and 87.0%(20 strains), respectively. They were sensitive to other beta-lactam drugs. All the 23 strains of mucoid Haemophilus influenzae infected children were Hib, and the main ST types were ST386 and ST18. It is very important to advocate Hib vaccination.

Objective:To analyze the immunization status of routine vaccines for children aged 0-7 years old with special health status in Tianhe District, Guangzhou City, from 2023 to 2024.Methods:From April 2023 to March 2024, 42 vaccination units in Tianhe District, Guangzhou, were organized to collect data on diseases and vaccination history of children with special health status. Vaccination rates were calculated, and multivariate logistic regression models were used to explore the impact of special health status on vaccination rates.Results:A total of 1 976 children aged 0-7 years old with special health status were included, with an average of (1.26±0.58) diseases per participant. The average number of vaccine doses administered for routine immunizations was (14.29±4.27), and the full vaccination coverage was 72.76%. The vaccination rate of 10 doses in the immunization program vaccine was less than 90.00%. The timely rate of the first dose of hepatitis B vaccine (HepB1) was 74.14%, and that of the first dose of measles vaccine (MCV1) was 63.93%. Compared with children with infectious diseases, those with neonatal diseases were more likely to miss the third dose of poliomyelitis vaccine (PV3), MCV1 and the second dose of Group A meningococcal polysaccharide vaccine (MPSV-A2). Those with neuromuscular system diseases were more likely to miss PV3, MPSV-A2 and the first dose of Japanese encephalitis vaccine, live (JE-L1). Those with congenital heart disease were more likely to miss PV3, the third dose of diphtheria tetanus-acellular pertussis vaccine (DTaP3), MCV1, MPSV-A2, and JE-L1. Those with hematological disorders were more likely to miss PV3, MCV1, MPSV-A2, and JE-L1. Those with genetic diseases were more likely to miss MPSV-A2. Those with comorbidities were more likely to miss MCV1 and MPSV-A2. Those with neonatal diseases, neuromuscular system diseases, congenital heart disease, hematopoietic system diseases, genetic diseases, or comorbidities had difficulties in completing the full vaccination process.Conclusion:Children with special health conditions have lower rates of routine immunization and timely vaccination. More measures are needed to improve vaccination rates.

Objective:To explore the value and related mechanism of preoperative serum sialic acid (SA) on evaluating microvascular invasion (MVI) in patients with intrahepatic cholangiocarcinoma (ICC).Methods:A total of 91 patients who underwent surgical resection and were pathologically diagnosed with ICC from December 2020 to September 2024 at the Oriental Hepatobiliary Surgery Hospital affiliated to the Naval Medical University were included in this retrospective analysis. The patients were divided into non-MVI (41 cases) and MVI groups (50 cases). The general data and laboratory examination indexes were collected and analyzed. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for predicting MVI. The predictive value of serum indicators for MVI was evaluated by receiver operating characteristic curves. The correlation between MVI and SA was analyzed by point-biserial correlation. ICC cells stably overexpressing β-galactoside α2, 6-sialyltransferase 1 (ST6GAL1) were generated through lentiviral transfection. ST6GAL1 protein expression and mRNA expression were detected by Western blot and quantitative real-time polymerase chain reaction, respectively. Sambucus nigra (SNA) lectin fluorescence staining was used to detect α2, 6-sialylation levels on cells. Cell migration ability was assessed by wound healing and Transwell assays, and cell proliferation was evaluated by colony formation assays.Results:Compared with the non-MVI group, patients in the MVI group exhibited significantly higher levels of fibrinogen, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, SA and 5′-nucleotidase (5′-NT) (all P<0.05). Multivariate logistic regression analysis revealed that SA ( OR=1.01,95% CI 1.01-1.02, P=0.023) was the only independent predictor for MVI. The area under curve of SA in predicting MVI was 0.757 (95% CI 0.640-0.870), sensitivity 67.65%, specificity 77.78%. SA was positively correlated with MVI ( r=0.443, P<0.001). ICC cells overexpressing ST6GAL1 were featured with increased mean fluorescence intensity of SNA lectin, and increased level of α2, 6-sialylation on the cell surface (both P<0.05). The number of colonies formed by hypersialylated ICC cells was also increased ( P<0.05), and both the migration rate and the number of migrating cells were significantly higher ( P<0.05). Conclusions:Serum SA is an independent predictor for MVI in ICC patients. Hypersialylation in ICC cells is associated with higher malignancy.

Organ transplantation is an effective treatment for end-stage organ failure, but postoperative infections and rejection reactions are key factors affecting the survival of the patients. Recently, the incidence of human parvovirus B19 (B19V) infection following transplantation has increased. B19V is a non-enveloped virus that primarily infects the upper respiratory tract and exhibits significant tropism for erythroid progenitor cells in the bone marrow, leading to the lysis of erythrocytes and hematological abnormalities. After B19V viremia, it may further infect other cells, triggering inflammatory responses and tissue damage. B19V infection may lead to chronic anemia in organ transplant patients, thereby affecting the success of the transplant and the survival of the patients. Therefore, it is essential to diagnose and monitor B19V infection post-transplantation. Due to the immunosuppressive therapy following transplantation, traditional serological detection methods, such as IgM and IgG antibody tests, are often unreliable. In contrast, molecular biological detection, especially real-time fluorescent quantitative PCR technology, provides more accurate results. However, the diversity of B19V genotypes may lead to the missed detection of some genotypes. Thus, it is necessary to use different detection techniques to improve the diagnostic accuracy of B19 virus infections. Additionally, there is a need to explore more precise diagnostic methods to enhance the early identification and management of B19V infection, further improving the survival and life quality of the patients.

Objective:This study aimed to analyze the infection status of viral viruria within one year after kidney transplantation, its impact on renal allograft function, and associated risk factors.Methods:A retrospective case-control study was conducted, involving 370 patients who underwent allogeneic kidney transplantation at Renji Hospital, Shanghai Jiao Tong University School of Medicine, from January 1, 2020 to December 31, 2021. Urinary viral loads of BK virus (BKV), JC virus (JCV), cytomegalovirus (CMV), and Epstein-Barr virus (EBV) were detected using PCR fluorescent probe assays. Patients were categorized into infection and non-infection groups. Glomerular filtration rate (GFR) and tacrolimus trough concentration was measured during infections, and clinical data were collected. Univariate analysis was performed to identify risk factors for viral viruria.Results:The 1-year patient survival rate and graft survival rate were both 98.6%. The incidence rates of viral viruria were as follows: JCV (42.7%), BKV (29.7%), CMV (11.6%), and EBV (2.9%), with statistically significant differences among viruses ( P<0.001). Single viral infection accounted for 48% of cases, while co-infections were predominantly BKV+JCV (9%). JCV infection rates remained consistently high throughout the year (22.4%-28.9%), whereas BKV infections peaked at 3 months postoperatively (20.5%). Co-infection with low-load JCV (>2 000 copies/ml) and CMV (>6 000 copies/ml) led to a significant decline in GFR at 6 months post-transplantation [median difference: 16.7 ml/(min×1.73 m2), P=0.019]. Univariate analysis revealed that elevated tacrolimus trough concentration was independent risk factor for BKV (4.90 vs. 4.30 ng/ml, Z=4.29, P<0.001) and JCV infections (5.30 vs. 4.80 ng/ml, Z=4.25, P<0.001). Conclusion:High incidences of JCV and BKV infections were observed post-kidney transplantation. Co-infection with low-load JCV and CMV accelerates renal function impairment, highlighting the critical role of tacrolimus concentration management in reducing viral infection risks.
