ObjectiveTo investigate the association and translational mechanism between the hepatotoxicity of Xianling Gubao (XLGB) and its treatment of osteoporosis based on a zebrafish model. MethodsZebrafish were randomly selected four days after fertilization (4 dpf) and exposed to different concentrations of XLGB (0.7,0.35 mg·L-1) for 96 h. At the endpoint of the exposure, the mortality rates of zebrafish in the treatment groups of different concentrations were counted, and the "dose-toxicity" curves were plotted. The 10% sublethal concentration (LC10) was calculated. The liver area, acridine orange staining, and pathological tissue sections of transgenic zebrafish [CZ16 (gz15Tg.Tg (fabp 10a: ds Red; ela31: EGFP)] were used as indicators to confirm the hepatic damage caused by the sublethal concentration of XLGB. By using the prednisolone (PNSL)-induced osteoporosis model of zebrafish, the anti-osteoporosis activity of XLGB was evaluated by using the area of skull stained by alizarin red and the cumulative optical density value as indicators. Then, the toxicity difference of XLGB on the liver of zebrafish in healthy and osteoporotic states was compared, and the mechanism of the translational action of the toxicity of XLGB was predicted based on network pharmacology and real-time polymerase chain reaction(Real-time PCR). ResultsThe LC10 of XLGB on zebrafish (8 dpf) was 0.7 mg·L-1. Compared with the blank group, the sublethal concentration (LC10=0.7 mg·L-1, 1/2 LC10=0.35 mg·L-1) of XLGB induced an increase in the number of apoptosis of hepatocytes in a dose-dependent manner, and the tissue arrangement of the liver was disordered and loose. The vacuoles were obvious, and the fluorescence area of the liver was significantly reduced (P<0.01). Compared with the blank group, the mineralized area and cumulative optical density value of zebrafish skull in the PNSL model group were significantly reduced (P<0.01), and those in the 0.7,0.35 mg·L-1 XLGB treatment group were significantly increased compared with the model group (P<0.01). Most importantly, 0.7 mg·L-1 XLGB had no significant effect on the liver of zebrafish in the osteoporosis disease model compared with the blank group. The results of network pharmacology and real-time PCR experiments showed that the toxic transformation of XLGB might be related to the differences in the expression levels of key targets, such as tumor protein 53 (TP53), cysteine aspartic acid specific protease-3(Caspase-3), interleukin(IL)-6, and alkaline phosphatase(ALP) in different organismal states. ConclusionUnder certain conditions, XLGB has hepatotoxicity in normal zebrafish, but under osteoporotic conditions, XLGB not only exerts significant anti-osteoporosis activity but also alleviates hepatotoxicity significantly, which provides a reference for the safe clinical use of XLGB and real evidence for the theories of traditional Chinese medicine of attacking poison with poison and of treating disease with corresponding drugs without damage to the body.

Tumor drug resistance is an important problem in the failure of chemotherapy and targeted drug therapy, which is a complex process involving chromatin remodeling. SWI/SNF is one of the most studied ATP-dependent chromatin remodeling complexes in tumorigenesis, which plays an important role in the coordination of chromatin structural stability, gene expression, and post-translation modification. However, its mechanism in tumor drug resistance has not been systematically combed. SWI/SNF can be divided into 3 types according to its subunit composition: BAF, PBAF, and ncBAF. These 3 subtypes all contain two mutually exclusive ATPase catalytic subunits (SMARCA2 or SMARCA4), core subunits (SMARCC1 and SMARCD1), and regulatory subunits (ARID1A, PBRM1, and ACTB, etc.), which can control gene expression by regulating chromatin structure. The change of SWI/SNF complex subunits is one of the important factors of tumor drug resistance and progress. SMARCA4 and ARID1A are the most widely studied subunits in tumor drug resistance. Low expression of SMARCA4 can lead to the deletion of the transcription inhibitor of the BCL2L1 gene in mantle cell lymphoma, which will result in transcription up-regulation and significant resistance to the combination therapy of ibrutinib and venetoclax. Low expression of SMARCA4 and high expression of SMARCA2 can activate the FGFR1-pERK1/2 signaling pathway in ovarian high-grade serous carcinoma cells, which induces the overexpression of anti-apoptosis gene BCL2 and results in carboplatin resistance. SMARCA4 deletion can up-regulate epithelial-mesenchymal transition (EMT) by activating YAP1 gene expression in triple-negative breast cancer. It can also reduce the expression of Ca2+ channel IP3R3 in ovarian and lung cancer, resulting in the transfer of Ca2+ needed to induce apoptosis from endoplasmic reticulum to mitochondria damage. Thus, these two tumors are resistant to cisplatin. It has been found that verteporfin can overcome the drug resistance induced by SMARCA4 deletion. However, this inhibitor has not been applied in clinical practice. Therefore, it is a promising research direction to develop SWI/SNF ATPase targeted drugs with high oral bioavailability to treat patients with tumor resistance induced by low expression or deletion of SMARCA4. ARID1A deletion can activate the expression of ANXA1 protein in HER2+ breast cancer cells or down-regulate the expression of progesterone receptor B protein in endometrial cancer cells. The drug resistance of these two tumor cells to trastuzumab or progesterone is induced by activating AKT pathway. ARID1A deletion in ovarian cancer can increase the expression of MRP2 protein and make it resistant to carboplatin and paclitaxel. ARID1A deletion also can up-regulate the phosphorylation levels of EGFR, ErbB2, and RAF1 oncogene proteins.The ErbB and VEGF pathway are activated and EMT is increased. As a result, lung adenocarcinoma is resistant to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). Although great progress has been made in the research on the mechanism of SWI/SNF complex inducing tumor drug resistance, most of the research is still at the protein level. It is necessary to comprehensively and deeply explore the detailed mechanism of drug resistance from gene, transcription, protein, and metabolite levels by using multi-omics techniques, which can provide sufficient theoretical basis for the diagnosis and treatment of poor tumor prognosis caused by mutation or abnormal expression of SWI/SNF subunits in clinical practice.

Objective:
To explore the relationship between parenting styles and depressive symptoms in adolescents with nightmare disorder, so as to provide a scientific basis for formulating effective family intervention measures and psychological counseling.
Methods:
From January 2023 to August 2024, 90 adolescents diagnosed with nightmare disorder and admitted to Hangzhou Seventh Peoples Hospital, along with 176 healthy controls from the urban areas of Hangzhou, were recruited as participants in the study. All participants were assessed using the Nightmare Experience Questionnaire (NEQ), Family Relationship Questionnaire (FRQ), and Plutchik-van Praag Selfreport Depression Scale (PVP). The ttest and Chisquare test were conducted to compare two groups. Pearson correlation and stepwise multiple linear regression were employed to explore the correlations between PVP and NEQ or FRQ. The Process model was used to testing the mediating effects among NEQ/FRQ/PVP.
Results:
The nightmare disorder group had higher scores in nightmare frequency, the four factors of NEQ (physical effect, negative emotion, meaning interpretation, horrible stimulation), and PVP than the healthy control group (24.86±18.89, 10.12±3.67, 19.01±3.51, 17.02±3.31, 15.14±3.26, 14.02±4.38; 2.34±1.04, 6.49±2.18, 17.63±4.76, 13.91±4.24, 12.40±4.49, 9.39±3.28)(t=15.79, 10.11, 2.43, 6.09, 5.14, 27.46, P<0.05). The nightmare disorder group reported significantly lower scores in FRQ general attachment and maternal encouragement than the healthy control group (7.22±2.81, 16.39±3.28) (t=-5.53, -4.95). In contrast, they exhibited significantly higher scores in maternal abuse, maternal dominance, paternal freedom release, and paternal dominance than the healthy control group (8.23±1.80, 13.11±3.73, 18.36±3.37, 12.04±3.29; 6.07±1.85, 8.48±3.80, 15.15±2.51, 9.47±3.03) (t=6.70, 8.96, 5.90, 7.04, P<0.01). The results of Pearson correlation analysis showed that, in the nightmare disorder group, the PVP score was positively correlated with negative emotion, nightmare frequency, maternal abuse, and maternal dominance score (r=0.14, 0.63, 0.26, 0.51, P<0.05). The results of multiple linear regression analysis showed that when using FRQ score to predict NEQ score, the adjusted R2 in the nightmare disorder group was 0.01-0.59. Mother abuse could prediced physical effect (β=0.33); maternal dominance significantly predicted negative emotion, horrible stimulation, and nightmare frequency (β=0.29, 0.30, 0.79); paternal freedom release could predict negative emotion (β=0.26), paternal dominance predicted both negative emotion and nightmare frequency (β=0.22, 0.45) (P<0.05). Mediation analysis further revealed that, in the nightmare disorder group, PVP scores served as a mediating variable between FRQ and NEQ.
Conclusion
Abusive, controlling, and neglectful family upbringing styles as well as depression maybe are key factors that may contribute to the development of nightmare disorder among adolescents.

ObjectiveTo investigate the regulatory effect and potential mechanisms of isocitrate dehydrogenase 3A (IDH3A) on cardiomyocyte hypertrophy. MethodsThe expression of IDH3A in the myocardium of healthy volunteers (n=10) and patients with heart failure (HF) (n=10), and in the myocardium of mice subjected to transverse aortic constriction (TAC) surgery and sham operation, as well as in phenylephrine (PE)-induced neonatal rat ventricular cardiomyocytes (NRVCs), was assessed by real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot assay. The effect of adenovirus-mediated overexpression of IDH3A on the expression of hypertrophy-related genes in PE-induced NRVCs was also evaluated. The effect of IDH3A on NRVCs area was examined by phalloidin staining assay. A mutant of IDH3A with abolished enzymatic activity, IDH3A_D208A, was generated through site-directed mutagenesis. The impact of this IDH3A mutant on the hypertrophic phenotype, ATP and ROS levels in NRVCs was evaluated to investigate whether the regulatory role of IDH3A in cardiomyocyte hypertrophy was dependent on its enzymatic activity. The effect of exogenous α-ketoglutaric acid (AKG) on cardiomyocyte hypertrophy was also detected by Western blot and phalloidin staining assay, respectively. ResultsIDH3A was significantly decreased in the myocardium of HF patients, in the myocardium of TAC-operated mice, and in PE-induced NRVCs (P = 0.005 2,P = 0.026 6,P = 0.041 3 and P = 0.006 6, respectively). Overexpression of IDH3A markedly suppressed the expression of hypertrophy-related genes and the increase of cell size of PE-induced NRVCs (P < 0.000 1, P = 0.000 1 and P = 0.000 2, respectively). The ATP and ROS analysis indicated that IDH3A inhibited the increases of ATP and ROS levels in PE-induced NRVCs (P = 0.001 2 and P<0.000 1, respectively), whereas the enzymatically inactive IDH3A mutant lacked this effect. Exogenous AKG provision could, but overexpression of IDH3A mutant failed to suppress PE-induced NRVCs hypertrophy. ConclusionIDH3A inhibits cardiomyocyte hypertrophy via elevating AKG level, providing scientific evidence for study on IDH3A-based treatment of cardiac hypertrophy.

ObjectiveTo investigate the clinical efficacy and potential mechanism of Shengmai Jiuxin decoction in the treatment of acute decompensated heart failure (ADHF) with the traditional Chinese medicine (TCM) pattern of Qi and Yin deficiency, Yang deficiency, and blood stasis. MethodsA total of 68 patients diagnosed with ADHF of Qi and Yin deficiency, Yang deficiency, and blood stasis type were randomly assigned to an observation group (34 cases) and a control group (34 cases). Both groups received conventional Western medical treatment, while the observation group was additionally administered Shengmai Jiuxin decoction. Parameters compared before and after treatment included: TCM syndrome score, TCM syndrome efficacy, New York Heart Association (NYHA) functional classification, left ventricular ejection fraction (LVEF), N-terminal pro-B-type natriuretic peptide (NT-proBNP), six-minute walk distance (6MWD), hypoxia-inducible factor-1 alpha (HIF-1α), vascular endothelial growth factor A (VEGF-A), Caspase-3, and the number of rehospitalizations for heart failure within one month after discharge. ResultsThere were no significant differences in sex, age, vital signs, or underlying diseases between the two groups. Compared with baseline, both groups exhibited significant reductions in TCM syndrome scores, NT-proBNP, and HIF-1α levels (P<0.01), as well as significant increases in 6MWD, LVEF, VEGF-A, and Caspase-3 levels (P<0.05, P<0.01). After treatment, the observation group showed significantly greater reductions in TCM syndrome score, NT-proBNP, HIF-1α, and Caspase-3 levels compared with the control group (P<0.05) and significantly greater increases in 6MWD, TCM syndrome efficacy, and VEGF-A levels (P<0.05). No significant differences were observed between the groups in NYHA functional classification, LVEF, or the number of rehospitalizations for heart failure within one month after discharge. No drug-related adverse events were reported in either group during the treatment period. ConclusionShengmai Jiuxin decoction can improve cardiac function and clinical symptoms in patients with ADHF of Qi and Yin deficiency, Yang deficiency, and blood stasis type. Its mechanisms may be related to the regulation of the HIF-1 signaling pathway by modulating targets such as HIF-1α, VEGF-A, and Caspase-3.

Objective To assess the nutritional status in elderly patients with chronic renal insufficiency (CRI) and reveal the key factors affecting the nutritional status. Methods A total of 310 elderly patients with CRI who received hospitalization treatment and outpatient follow-up in the hospital from January 2021 to June 2024 were selected as the investigation subjects. The nutritional status of patients was evaluated by mini-nutritional assessment (MNA) questionnaire, and the nutritional status and dietary structure of patients were comprehensively evaluated by anthropometric indicators [height, weight, body mass index (BMI), upper arm circumference, calf circumference], biochemical indicators [serum albumin (ALB), prealbumin (PA), hemoglobin (Hb), transferrin (TF)] and 24-hour dietary review method. According to the investigation results of nutritional status, the patients were divided into good nutrition group (MNA score≥24 points), nutritional risk group (MNA score of 17-23.5 points) and malnutrition group (MNA score<17 points). Univariate analysis was adopted to screen the potential influencing factors of elderly CRI. Multivariate logistic regression model was applied to analyze the influencing factors of malnutrition in elderly CRI patients. Results Among the 325 questionnaires were distributed, but only 310 valid questionnaires were recovered, with an effective recovery rate of 95.38%. Investigation results revealed that among the 310 patients, 29.35% (91 cases) had good nutritional status, and 42.26% (131 cases) had nutritional risk, and 28.39% (88 cases) had malnutrition. Univariate analysis indicated that there were statistical differences in BMI, CRI staging, serum ALB, PA, Hb, TF, protein intake and total calorie intake among the good nutrition group, the nutritional risk group and the malnutrition group (P<0.05). Multivariate logistic regression analysis suggested that low BMI (OR=0.903, 95%CI: 0.867-0.941), high CRI stage (OR=1.091, 95%CI: 1.053-1.130), low serum ALB (OR=0.907, 95%CI: 0.867-0.948), PA (OR=0.918, 95%CI: 0.888-0.949), Hb (OR=0.944, 95%CI: 0.909-0.997), TF (OR=0.912, 95%CI: 0.874-0.952), insufficient protein intake (OR=0.924, 95%CI: 0.882-0.969) and insufficient total calorie intake (OR=0.938, 95%CI: 0.909-0.968) were influencing factors for malnutrition in elderly patients with CRI (all P<0.05). Drawing ROC curve of malnutrition in elderly patients with CRI according to the prediction probability of logistic regression model found that the AUC, sensitivity, specificity, 95%CI and Youden index were 0.976, 93.18%, 92.34%, 0.953-0.990 (P<0.05) and 0.855. Conclusion The incidence rate of malnutrition is high in elderly patients with CRI, and is mainly affected by factors such as low BMI, high CRI stage, low serum ALB, PA, Hb and TF levels and insufficient protein and total calorie intakes. In addition, logistic regression model has high predictive value and can provide a reference for early clinical identification of high-risk population with malnutrition among elderly patients with CRI.

Objective To analyze the current status of dietary quality in patients with chronic atrophic gastritis (CAG), and to explore the influencing factors of dietary quality. Methods A retrospective study was conducted on 550 patients with CAG admitted to the hospital from April 2021 to April 2024. Self-made basic data questionnaire, dietary balance index (DBI), and hospital anxiety and depression scale-anxiety subscale (HADS-A) were used for investigation. Multivariate linear regression analysis was applied to analyze the influencing factors of DBI-lower bound score (LBS). Results The average score of DBI-LBS in 550 patients with CAG was (31.45±8.53) points. There were significant differences in DBI-LBS scores among CAG patients in terms of age, body mass index (BMI), Helicobacter pylori (HP) infection, marital status, drinking history, smoking history, CAG severity, HADS-A score and concurrent gastrointestinal diseases (P<0.05). Multivariate linear regression analysis of the above influencing factors indicated that BMI, smoking history, HADS-A score and CAG severity were independent influencing factors of DBI-LBS score in CAG patients (P<0.05). Conclusion The general dietary quality is not optimistic in CAG patients, showing a moderate deficiency in dietary intake. BMI, disease severity and psychological status of patients are independent factors affecting dietary quality.
