ObjectiveTo observe the clinical efficacy of Tangshen Dihuang decoction in treating diabetic kidney disease (DKD) with liver-kidney Yin deficiency and blood stasis syndrome and its impact on gut microbiota. MethodsA randomized controlled clinical trial was conducted, in which 102 DKD patients with liver-kidney Yin deficiency and blood stasis syndrome were randomly assigned to the Tangshen Dihuang decoction group and the control group. Each group consisted of 51 cases, and the treatment period was 3 months. The primary efficacy indicators included urinary albumin-to-creatinine ratio (UACR), fasting blood glucose (FBG), 2-hour postprandial blood glucose (2 hPBG), glycated hemoglobin (HbA1C), serum creatinine (SCr), blood urea nitrogen (BUN), angiotensinⅡ (AngⅡ), serum cystatin C (Cys-C), urinary N-acetyl-β-D-glucosaminidase (NAG), urinary β2-microglobulin (Uβ2-MB), traditional Chinese medicine (TCM) symptom scores, and gut microbiota. ResultsAfter treatment, the total response rate in the Tangshen Dihuang decoction was 87.23% (41/47), which was higher than that (69.57%, 32/46) in the control group (Z=4.30, P<0.05). After treatment, the TCM symptom scores decreased in both groups (P<0.01) and were lower in the Tangshen Dihuang decoction group than in the control group (P<0.01). After treatment, the control group showed decreases in UACR, Uβ2-MG, AngⅡ, and FBG (P<0.05) as well as 2 hPBG and HbA1C (P<0.01), and no significant differences in BUN, Cys-C, eGFR, SCr, and NAG. The Tangshen Dihuang decoction group showed increased eGFR (P<0.05), declined levels of UACR, BUN, Cys-C, Uβ2-MB, AngⅡ, FBG, 2 hPBG, NAG, and HbA1C (P<0.01), and no significant difference in SCr. The Tangshen Dihuang decoction group had lower BUN (P<0.05), Cys-C (P<0.05), AngⅡ (P<0.05), 2 hPBG (P<0.05), Uβ2-MG (P<0.01), and NAG (P<0.01) and higher eGFR level (P<0.05) than the control group. After treatment, the control group showed declines in Shannon, Observed_species, and Chao1 indices (P<0.05). The samples from both groups showed statistically significant differences in the principal coordinates analysis (PCoA) plot based on Anosim analysis (P<0.05). After treatment, the Tangshen Dihuang decoction group showed decreased relative abundance of Actinobacteria (P<0.05). Moreover, the relative abundance of Actinobacteria was significantly lower in the Tangshen Dihuang decoction group than in the control group (P<0.05). At the genus level, the control group showed decreased relative abundance of Bifidobacterium (P<0.05), and the Tangshen Dihuang decoction group presented increased relative abundance of Bifidobacterium and Blautia_A (P<0.05). After treatment, the Tangshen Dihuang decoction group had higher relative abundance of Bifidobacterium than the control group (P<0.01). ConclusionTangshen Dihuang decoction has a significant therapeutic effect on DKD patients with liver-kidney Yin deficiency and blood stasis syndrome. It can markedly relieve clinical symptoms and reduce proteinuria and postprandial blood glucose by antagonizing the local renin-angiotensin system (RAS) and alleviating gut microbiota dysbiosis.

OBJECTIVES:
To investigate the impact of prenatal fear stress on placental amino acid transport and emotion and cognition development in offspring rats.
METHODS:
Thirty pregnant Wistar rats were randomized equally into control and fear stress (induced using an observational foot shock model) groups. In each group, placental and serum samples were collected from 6 dams on gestational day 20, and the remaining rats delivered naturally and the offspring rats were raised under the same conditions until 8 weeks of age. Emotional and cognitive outcomes of the offspring rats were assessed with behavioral tests, and placental structure was examined using HE staining. Bioinformatics analysis was used to identify differentially expressed placental transporter genes under fear stress. The expressions of system A and system L amino acid transporters, along with other specialized transporters, were detected using qRT-PCR and Western blotting. Fetal serum amino acid concentrations were determined by HPLC. The correlations between fetal amino acid levels and behavioral outcomes of the offspring rats were analyzed.
RESULTS:
The dams with fear stress showed reduced open-field activity and increased freezing behavior with significantly decreased placental weight, fetal weight, and fetal-to-placental ratio. Bioinformatics analysis revealed 28 differentially expressed transporter genes involved mainly in amino acid transport. In the fear stress group, fetal serum amino acid levels were significantly lowered and Slc38a1, Slc43a1, Slc43a2, Slc7a8, Slc6a6, Slc1a1 and Slc6a9 mRNA and protein expressions were all downregulated. The offspring rats in fear stress group exhibited decreased novel object preference and spontaneous alternation with reduced open arm exploration and increased immobility in emotional tests. Lower early-life amino acid levels was found to correlate with impaired adult cognition.
CONCLUSIONS
Prenatal fear stress in rats impairs placental amino acid transporter expression and reduces fetal serum amino acid levels, potentially contributing to long-term cognitive deficits in the offspring rats.

Dry eye disease(DED)refers to a condition characterized by reduced stability of the tear film or an imbalance in the microenvironment of the ocular surface, resulting from abnormalities in quality, quantity and kinetics of tear. This condition leads to various ocular discomforts and even visual impairment. The pathogenesis of DED is multifactorial and current treatment mainly focuses on symptom relief and preservation of visual function. Acupuncture has shown effectiveness in treating dry eye, although its underlying mechanism remains incompletely understood. Proteomics technology offers a comprehensive and systematic approach to studying the functions, structures and interactions of proteins. Its application in DED research can provide valuable insights into the dynamic changes in protein levels associated with different etiology or the course of DED and facilitate the identification of potential biomarkers. Furthermore, proteomics can systematically explore the regulatory mechanisms underlying acupuncture treatment for DED, providing a theoretical basis for acupuncture treatment research and contributing to the understanding of its effects at a fundamental level. This paper aims to explore the potential application of proteomics in both clinical and basic research on DED. Ultimately, it strives to offer scientific and effective strategies for the diagnosis and treatment of DED and advance our knowledge of the mechanisms underlying acupuncture therapy.

Neutrophils play an immune defense role by releasing the proteases such as neutrophil elastase and myeloperoxidase to form neutrophil extracellular trap (NET) and participate in the inflammatory response of various liver diseases, but the excessive release of NET may worsen liver tissue damage and has thus become one of the risk factors for liver diseases. In recent years, studies have shown that the excessive release of NET can promote the progression of liver diseases (such as viral hepatitis, nonalcoholic steatohepatitis, and hepatic ischemia-reperfusion injury) to liver cancer, and clarifying the mechanism of action of NET is of great importance for the diagnosis and progression of liver diseases. Therefore, this article elaborates on the latest research advances in NET in liver diseases, so as to provide new insights into the diagnosis and treatment of liver diseases and the prevention of liver cancer.

Objective To investigate the expression of neutrophil extracellular traps (NETs) and phagocytic function in the peripheral blood of patients with hepatic alveolar echinococcosis (HAE), and to examine their correlations with clinical inflamma tory indicators and liver functions. Methods A total of 50 patients with HAE admitted to Department of Hepatobiliary and Pancreatic Surgery, The Affiliated Hospital of Qinghai University from August 2022 to June 2023 were enrolled, while 50 age- and gender-matched healthy individuals from the Centre for Healthy Examinations of the hospital during the same period served as controls. The levels of NETs markers neutrophil myeloperoxidase (MPO) and neutrophil elastase (NE) were measured using enzyme-linked immunosorbent assay (ELISA). Peripheral blood neutrophils were isolated using density gradient centrifugation, stimulated in vitro using phorbol 12-myristate 13 acetate (PMA), and the levels of MPO and citrullination histone H3 (CitH3) released by neutrophils were quantified using flow cytometry. The phagocytic functions of neutrophils were examined using flow cytometry. In addition, the correlations of MPO and NE levels with clinical inflammatory indicators and liver biochemical indicators were examined using Spearman correlation analysis among HAE patients. Results The peripheral blood plasma MPO[(417.15 ± 76.08) ng/mL vs. (255.70 ± 80.84) ng/mL; t = 10.28, P < 0.05], NE[(23.16 ± 6.75) ng/mL vs. (11.92 ± 3.17) ng/mL; t = 10.65, P < 0.05]and CitH3 levels[(33.93 ± 18.93) ng/mL vs. (19.52 ± 13.89) ng/mL; t = 4.34, P < 0.05]were all significantly higher among HAE patients than among healthy controls, and a lower phagocytosis rate of neutrophils was detected among HAE patients than among healthy controls[(70.85 ± 7.32)% vs. (94.04 ± 3.90)%; t = 20.18, P < 0.05], and the ability to produce NETs by neutrophils was higher among HAE patients than among healthy controls following in vitro PMA stimulation. Pearson correlation analysis showed that the phagocytosis rate of neutrophils correlated negatively with platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), interleukin-6 (IL-6) level and C-reactive protein (CRP) level (rs = −0.515 to −0.392, all P values < 0.05), and the MPO and NE levels positively correlated with inflammatory markers NLR, PLR, CRP and IL-6 (rs = 0.333 to 0.445, all P values < 0.05) and clinical liver biochemical indicators aspartic transaminase, alanine aminotransferase, direct bilirubin and total bilirubin among HAE patients (rs = 0.290 to 0.628, all P values < 0.001). Conclusions Excessive formation of NETs is found among HAE patients, which affects the phagocytic ability of neutrophils and results in elevated levels of inflammatory indicators. NETs markers may be promising novel biomarkers for early diagnosis, monitoring, and severity assessment of liver disease.

Objective:To investigate the clinical value of multiparametric myocardial imaging using a dual-layer detector spectral CT in the non-invasive preoperative assessment of patients with coronary atherosclerotic heart disease (CHD) undergoing percutaneous coronary intervention (PCI).Methods:The clinical and imaging data of 90 patients who underwent coronary CT angiography (CCTA) with dual-layer spectral detector CT and invasive coronary angiography (ICA) within 30 days at the Affiliated Changshu Hospital of Nantong University from January 2021 to October 2022 were retrospectively analyzed. A total of 189 coronary arteries were included in the study cohort. The patients were divided into PCI ( n=44) and non-PCI groups ( n=46) according to whether they received PCI after evaluation with ICA. The diameter stenosis rate of the coronary arteries, myocardial iodine concentration (IC) and effective atomic number (Z eff) values were obtained from CCTA conventional and spectral images. The IC values and Z eff values of the myocardium in the areas with abnormal perfusion were compared with those in the areas with normal perfusion. The diagnostic performance of these parameters, as well as their combined model, was evaluated and compared using receiver operating characteristic (ROC) curve and area under the curve (AUC) in the pre-PCI assessment of patients with CHD. Results:Baseline patient data did not show statistically significant differences between the PCI and non-PCI groups (all P>0.05). There were statistically significant differences in IC values [(0.42±0.28) and (2.26±0.48) mg/ml] and Z eff values (7.39±0.33 and 8.50±0.25) between the myocardium areas with abnormal perfusion and the myocardium areas with normal perfusion in all patients (all P<0.001). The AUC for assessing whether patients with CHD need PCI treatment using myocardial IC and Z eff values were 0.865 and 0.853, respectively, which were significantly higher than assessment based only on lumen diameter stenosis rate (AUC=0.726, P<0.001). Conclusions:The IC and Z eff derived from myocardial spectral images can be used to diagnose myocardial perfusion abnormalities in patients with CHD. The spectral myocardial multi-parameters imaging shows promising potentials in pre-PCI assessment of patients with CHD, which can improve the efficiency of evaluation and may help to avoid unnecessarily invasive procedures.
