ObjectiveTo explore the potential mechanism of Changji'an Formula (肠激安方) on intestinal permeability for rats with diarrhea-predominant irritable bowel syndrome (IBS-D) of liver depression and spleen deficiency syndrome by the microRNA-29b-3p (miR-29b-3p)/tumor necrosis factor receptor-associated factor 3 (TRAF3)/nuclear factor-κB (NF-κB)/myosin light chain kinase (MLCK) axis. MethodsTwenty-four 1-day-old male Sprague-Dawley (SD) suckling rats were selected, and the IBS-D rat model of liver depression and spleen deficiency syndrome was established via a three-factor method,i.e. maternal separation plus acetic acid stimulation and restraint stress, for 6 consecutive weeks. After successful modeling, the rats were randomly divided into a model group, pinaverium bromide group, low-dose and high-dose Changji'an Formula groups, with 6 rats in each group. Another 6 age-matched non-modeled SD rats were included as the control group. The low-dose and high-dose Changji'an Formula groups were given intragastric administration of Changji'an Formula solution at doses of 16.74 g/(kg·d) and 33.48 g/(kg·d), respectively; the pinaverium bromide group received intragastric administration of pinaverium bromide tablets at 0.018 g/(kg·d); and the control group was given distilled water at 10 ml/(kg·d) via intragastric gavage. The intervention was conducted once daily for 14 consecutive days. After the gavage treatment, the fecal water content of rats in each group was measured. Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum levels of intestinal permeability indicators, including D-lactic acid (D-LA), diamine oxidase (DAO), and lipopolysaccharide (LPS). Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to determine the mRNA expression levels of miR-29b-3p, TRAF3, tumor necrosis factor-α (TNF-α), p65, p50, and MLCK in colonic tissues. Western Blot analysis was employed to detect the protein expression levels of TRAF3, TNF-α, p65, phosphorylated p65 (p-p65), MLCK, myosin light chain (MLC), phosphorylated MLC (p-MLC), and tight junction proteins including junctional adhesion molecule-A (JAM-A), Occludin, and Claudin-1 in colonic tissues. ResultsCompared with the control group, the model group exhibited significantly increased fecal water content and serum levels of D-LA, DAO, and LPS, along with decreased protein expression levels of JAM-A, Occludin, and Claudin-1 in colonic tissues (P<0.05 or P<0.01). Additionally, in the model group, the mRNA expression levels of miR-29b-3p, TNF-α, p65, p50, and MLCK in colonic tissues were up-regulated, while the mRNA and protein expression levels of TRAF3 were down-regulated; the protein levels of TNF-α and MLCK, as well as the ratios of p-p65/p65 and p-MLC/MLC, significantly elevated (P<0.01). Compared with the model group, all treatment groups showed reduced fecal water content and serum levels of D-LA, DAO, and LPS, along with down-regulated mRNA expression levels of miR-29b-3p, TNF-α, p65, p50, and MLCK, and up-regulated TRAF3 mRNA expression in colonic tissues. Moreover, the pinaverium bromide group and high-dose Changji'an Formula group presented increased protein levels of Occludin, Claudin-1, and TRAF3, as well as decreased protein levels of TNF-α and MLCK, and reduced ratios of p-p65/p65 and p-MLC/MLC in colonic tissues (P<0.05 or P<0.01). Compared with the low-dose Changji'an Formula group, the high-dose group had lower fecal water content and serum levels of DAO and LPS (P<0.01). In comparison with the pinaverium bromide group, the high-dose Changji'an Formula group showed a significant decrease in serum DAO level (P<0.01). ConclusionsChangji'an Formula can reduce intestinal permeability and restore intestinal barrier function in IBS-D rats of liver depression and spleen deficiency syndrome by regulating the miR-29b-3p/TRAF3/NF-κB/MLCK axis.

Objective To analyze the effect of releasing the lower pulmonary ligament on right residual lung expansion after right upper lobe resection under different body mass index (BMI) levels. Methods The clinical data of patients who underwent thoracoscopic right upper lobe resection in the First Affiliated Hospital with Nanjing Medical University from 2021 to 2022 were retrospectively analyzed. Patients were divided into a group A (17 kg/m2<BMI≤23 kg/m2), a group B (23 kg/m2<BMI≤29 kg/m2) and a group C (BMI>29 kg/m2) according to BMI. The presence of residual cavity was judged by chest X-ray at 7-10 days after operation, the degree of compensation change of the right main bronchus angle was measured, and the changes in lung volume were determined by CT three-dimensional reconstruction. Results A total of 157 patients who underwent thoracoscopic right upper lobe resection were included, including 71 males and 86 females, with an average age of (59.7±11.2) years. There were 50 patients in the group A, 75 patients in the group B, and 32 patients in the group C. In the group A, compared with those without releasing the lower pulmonary ligament, patients with releasing had a lower incidence of postoperative residual cavity (P=0.016), greater changes in bronchus angle (P<0.001), and smaller changes in lung volume (P<0.001). In the group B and C, there was no significant effect of releasing the lower pulmonary ligament on postoperative residual cavity, bronchus angle, and lung volume changes (P>0.05). Conclusion For patients with thin and long body shape and low BMI, releasing the lower pulmonary ligament is helpful to promote the expansion of the residual lung after right upper lobe resection and reduce the occurrence of postoperative residual cavity in patients.

Objective Magnetoreception, the remarkable ability of diverse animals to sense and utilize the geomagnetic field for orientation and navigation, remains a molecularly unresolved mystery in sensory biology. The putative magnetoreceptor (MagR, previously known as IscA1) is a highly conserved iron-sulfur protein implicated in both magnetoreception and iron metabolism; however, the functional diversity among its cross-species homologs remains poorly understood. Cellular morphology is a key genetically determined trait that can be altered through genetic or environmental modifications—a process known as cell morphology engineering. Constructing engineered cells with specific morphological features and magnetic sensitivity to achieve remote, non-invasive magnetic modulation represents a crucial goal in this field with significant application potential. Therefore, this study aims to systematically investigate the effects of MagR heterologous expression on bacterial morphology and magnetic sensing capabilities, screen for MagR-based magnetically sensitive morphology engineering pathways, and reveal the underlying molecular mechanisms. Methods We systematically screened 28 MagR homologous genes from diverse prokaryotic and animal taxa to evaluate their expression and corresponding phenotypic effects in Escherichia coli (E. coli). To compare the differential magnetic responses among bacteria expressing various recombinant MagR proteins, we utilized high-throughput automated bright-field microscopic imaging and scanning electron microscopy (SEM). Furthermore, comprehensive biochemical and biophysical characterizations of iron and iron-sulfur cluster binding were performed using Ferrozine colorimetric assays, electron paramagnetic resonance (EPR) spectroscopy, ultraviolet-visible (UV-Vis) absorption, and circular dichroism (CD) spectroscopy. Additionally, 100 mT static magnetic field (SMF) exposure experiments were conducted to assess magnetically tunable phenotypes, while the intrinsic magnetic properties of purified MagR proteins were directly measured using a superconducting quantum interference device (SQUID) magnetometer. Results Our results demonstrated that the heterologous expression of MagR homologs induced varying degrees of bacterial filamentation. From this comprehensive screen, two distinct morphological patterns were identified: hydra (Hydra vulgaris) MagR (hyMagR) promoted uniform cell elongation and filamentation, exhibiting robust magnetic sensitivity manifested as significantly enhanced filamentation under the 100 mT SMF. In contrast, pigeon (Columba livia) MagR (clMagR) induced only low-frequency, extreme filamentation (sporadically exceeding 80 μm) with a relatively weaker magnetic morphological response. Mechanistically, our data unambiguously proved that these phenotypic differences are primarily driven by distinct iron redox preferences rather than total cellular iron accumulation. Specifically, hyMagR preferentially binds ferrous iron (Fe2+), whereas clMagR favors ferric iron (Fe3+) and forms more stable iron-sulfur clusters. Intriguingly, although SQUID magnetometry showed that purified clMagR exhibited approximately five-fold higher mass magnetic susceptibility than hyMagR, its cellular magnetic response was weaker. We hypothesize that the Fe2+-preferred intracellular environment associated with hyMagR overexpression primes the cell for enhanced generation of reactive oxygen species (ROS) via the Fenton reaction. Exposure to an SMF synergizes with this primed redox state, triggering the bacterial SOS response and upregulating cell division inhibitors to efficiently induce uniform filamentation. Conclusion Our findings identify the Fe2+/Fe3+ redox state as a critical determinant of MagR-mediated morphological remodeling and magnetic responsiveness. This discovery suggests a potential strategy for engineering magnetically responsive cellular systems for synthetic biology applications, and provides a plausible framework, which potentially combines intrinsic protein magnetism with redox-state modulation, for further investigating the evolutionary mechanisms of MagR-mediated magnetoreception.

[Objective] To analyze the influencing factors of repeat blood donor lapsing using a zero-inflated poisson regression model (ZIP). [Methods] The blood donation behavior of 12 498 whole blood donors from 2020 was tracked until December 31, 2023. The factors influencing the frequency of blood donations in a given year was analyzed using ZIP, and donors with 0 blood donation in that year were considered to have lapsed. The changes in relevant influencing factors associated with each blood donation were measured and modeled for analysis. [Results] The zero-inflated part of ZIP showed that the risk of lapsing of male blood donors was 2.24 times that of female blood donors (OR 95% CI:1.864-2.696, P<0.001); the risk of lapsing of the 35-44 age group and over 45 age group was respectively 40% (OR 95% CI:0.455-0.790, P<0.001) and 61%(OR 95% CI:0.268-0.578, P<0.001) lower than that of the under 25 age group; the risk of lapsing for those who have donated blood twice and ≥3 times was respectively 50% (OR 95% CI:0.405-0.609, P<0.001) and 81% (OR 95% CI:0.154-0.225, P<0.001) lower than that of first-time donors; the risk of lapsing of those with junior high or high school education was 1.2 times that of those with a college degree or higher (OR 95% CI:1.033-1.384, P<0.05); the risk of lapsing for the divorced group was 2.02 times that of the married group (OR 95% CI:1.445-2.820, P<0.001); the risk of lapsing for those with an income (Yuan) of 10 000 to 50 000, 50 000 to 100 000 and more than 100 000 was respectively 0.67 (OR 95% CI:0.552-0.818, P<0.001), 0.72 (OR 95% CI:0.591-0.884, P=0.002) and 0.67 (OR 95% CI:0.535-0.834, P<0.001) times that of those with an income (Yuan) of less than 10 000. The results of the Poisson part are consistent with the results of the zero-inflated part in terms of age and education level. [Conclusion] Blood donor lapsing is overall related to factors such as gender, age, donation frequency, education, marital status and family income. It's essential to care for those blood donors prone to lapse to retain more regular blood donors.

OBJECTIVE:The optimal non-surgical therapy for chronic ankle instability remains unclear due to the continuous introduction of novel treatment methods despite the availability of several non-surgical options for improving foot and ankle function and dynamic balance in chronic ankle instability patients.This study aims to investigate the most effective non-surgical therapy options to improve foot and ankle function and dynamic balance for patients with chronic ankle instability using a network meta-analysis. METHODS:Using"CAI,exercise,and randomized controlled trial"as search terms,a literature search of PubMed,Embase,Cochrane Library,and Web of Science databases was conducted through a computer network to collect information from the databases from their inception to March 2024 on non-surgical therapies for the treatment of chronic ankle instability randomized controlled trials on foot and ankle function or dynamic balance in patients.EndNote software was utilized for literature management.RevMan 5.4 software and Cochrane Risk of Bias Assessment Tool were used to evaluate the risk of bias of the included literature.Paired meta-analysis and network meta-analysis of the outcomes such as the Foot and Ankle Ability Measure in daily living subscale score,Foot and Ankle Ability Measure in sports activities subscale score,Star Excursion Balance Test-Anterior score,Star Excursion Balance Test-Posteromedial score,Star Excursion Balance Test-Posterolateral score and Cumberland ankle instability tool score were performed using the network commands of Stata 14.0 software.The strength of evidence rating of the outcome metrics was evaluated according to the GRADE Level of Evidence and Strength of Recommendation Grading Criteria. RESULTS:Of the 22 randomized controlled trials that met the inclusion criteria,1 study was rated as low risk,8 studies were rated as medium risk,and 13 studies were rated as high risk,enrolling a total of 952 patients and 25 treatments.(1)Network meta-analysis showed that compared with the control group,Isokinetic Strength Training,Balance Training,Balance+Stroboscopic Glasses Training,Strength Training,Joint Mobilizations Training,CrossFit Training,CrossFit Training+Self-Mobilization,Wobble Board Training,National Academy of Sport Medicine corrective exercise program,Trigger Point Dry Needling,and Neuromuscular Training had different significant enhancement effects on improving foot and ankle function and dynamic balance in patients with chronic ankle instability(P<0.05).(2)Cumulative probability ranking results showed that the three treatments with the highest ranked Cumberland ankle instability tool score were Joint Mobilizations Training(88.6%)>Visual Feedback Balance Training(83.1%)>CrossFit Training+Self-Mobilization(74.8%);the three treatments with the highest ranked Star Excursion Balance Test-Anterior score were Joint Mobilizations Training(88.4%)>Isokinetic Strength Training(86.9%)>National Academy of Sport Medicine corrective exercise program(65.0%);the three treatments with the highest ranked Star Excursion Balance Test-Posteromedial score were Balance+Stroboscopic Glasses Training(87.4%)>Neuromuscular Training(74.6%)>Strength Training(68.9%);the three treatments with the highest ranked Star Excursion Balance Test-Posterolateral score were CrossFit Training+Self-Mobilization(74.6%)>Balance+Stroboscopic Glasses Training(70.0%)>Neuromuscular Training(63.7%);the three treatments with the highest ranked Foot and Ankle Ability Measure in daily living subscale score were National Academy of Sport Medicine corrective exercise program(91.9%)>Balance+Stroboscopic Glasses Training(85.6%)>Wobble Board Training(82.2%);the three treatments with the highest ranked Foot and Ankle Ability Measure in sports activities subscale score were Balance+Stroboscopic Glasses Training(93.5%)>Balance Training(86.7%)>National Academy of Sport Medicine corrective exercise program(86.4%). CONCLUSION:Non-surgical therapies can significantly improve foot and ankle function and dynamic balance in patients with chronic ankle instability.National Academy of Sport Medicine corrective exercise program had the best efficacy in improving foot and ankle daily activity function in chronic ankle instability patients;Balance+Stroboscopic Glasses Training had the best efficacy in improving foot and ankle sports function and posterior medial dynamic balance;Joint Mobilizations Training had the best efficacy in improving anterolateral dynamic balance and ankle instability condition;and CrossFit Training+Self-Mobilization had the best efficacy in improving posterior lateral dynamic balance.The strength of evidence for each outcome was low,influenced by the risk of methodological bias and risk of publication bias of the included studies.Therefore,the above conclusions need to be validated by more high-quality pilot studies.

Objective To comprehensively evaluate the multidimensional impact of the"Tianjin Experience"of Chest Pain Center(CPC)development on in-hospital mortality,optimization of treatment workflows,and regional coordination of care for patients with acute myocardial infarction(AMI),with the aim of providing scientific evidence to further improve the model and enhance AMI treatment outcomes.Methods This study analyzed data from the"Cardiovascular and Cerebrovascular Acute Events Surveillance System"maintained by the Tianjin Center for Disease Control and Prevention from 2013 to 2024.A segmented regression model was applied to assess the long-term trends in in-hospital mortality from acute myocardial infarction(AMI),with a particular focus on evaluating the impact of the chest pain center program on treatment outcomes.Additionally,supplementary analyses were conducted using surveillance data from the Tianjin Chest Pain Center Quality Control Team between 2017 and 2024.To verify the effectiveness of treatment process optimization,temporal trends in key time-based process indicators were assessed,including Door-in-Door-out(DIDO)time at non-PCI hospitals,Door-to-Wire(D-to-W)time,and First Medical Contact to Wire(FMC-to-W)to wire time.Results According to the data from the Tianjin Center for Disease Control and Prevention,the average 28-day AMI mortality rate in the overall patient population was 9.85%.Between 01/2013 and 12/2014,the mortality rate showed a significant upward trend(P<0.01),followed by a downward trend from 01/2015 to 12/2024,although the latter did not reach statistical significance(P>0.05).From 2013 to 2024,a total of 27 633 AMI cases with complete clinical records were collected from Tianjin Chest Hospital,with an average 28-day mortality rate of 4.55%.The mortality rate exhibited a decreasing trend from 01/2013 to 12/2016,with an annual percent change(APC)of-7.56(P<0.05).From 01/2017 to 12/2024,the trend stabilized,with an APC of 0.39(P>0.05).Conclusions The development of the CPC system in Tianjin significantly reduced key treatment times and improved the overall efficiency of AMI management.While population-level AMI mortality rates began to decline after 2015,the rate of improvement has slowed,indicating a continued need for optimizing the regional coordinated care system to further enhance patient outcomes.
