ObjectiveTo investigate the effect of Yishen Tongluo prescription (YSTLP) on apoptosis of renal tubular epithelial cells and explore the mechanism based on endoplasmic reticulum stress pathway of protein kinase R-like endoplasmic reticulum kinase (PERK)/activating transcription factor 4 (ATF4)/transcription factor C/EBP homologous protein (CHOP). MethodThe db/db mice were randomly divided into model group, valsartan group (10 mg·kg-1), and low, middle, high-dose YSTLP groups (1, 2.5, 5 g·kg-1). Samples were collected after eight weeks of drug intervention. In addition, db/m mice in the same litter served as the control group. Human renal tubular epithelial cells (HK-2) were cultured in vitro and divided into the control group, advanced glycated end-product (AGE) group, and AGE + low, middle, and high-dose YSTLP groups (100, 200, 400 mg·L-1). TdT-mediated dUTP nick end labeling (TUNEL) staining was used to detect the apoptosis rate of HK-2 cells. Methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay was conducted to detect the viability of HK-2 cells. Calcium fluorescence probe staining and luciferase reporter gene method were adopted to detect the luciferase activity of folded protein response element (UPRE) and endoplasmic reticulum stress. Immunohistochemical (IHC) analysis was carried out to measure the protein expressions of phosphorylated PKR (p-PERK), CHOP, and ATF4. Real-time polymerase chain reaction (Real-time PCR) was used to measure the mRNA expression levels of CHOP and X-box binding protein 1 (XBP1) in mouse kidney and HK-2 cells. Western blot was used to detect the protein expression level of p-PERK, PERK, CHOP, ATF4, B-cell lymphoma-2 (Bcl-2), Bcl-2 associated X protein (Bax), and cleaved Caspase-3 in mouse kidney and HK-2 cells. ResultIn the cellular assay, HK-2 cell viability was significantly reduced, and the apoptosis rate was elevated in the AGE group compared with the control group (P<0.01). The mRNA and protein expression levels of apoptosis-related factor Bcl-2 were significantly reduced (P<0.01), and those of Bax were significantly increased (P<0.01). The protein expression level of cleaved Caspase-3 was significantly increased (P<0.01). Compared with the AGE group, YSTLP administration treatment resulted in elevated cell viability and reduced apoptosis rate (P<0.01). The mRNA and protein expression levels of Bcl-2 were significantly elevated in a time- and dose-dependent manner (P<0.01), and those of Bax were significantly reduced in a time- and dose-dependent manner. The protein expression level of cleaved Caspase-3 was significantly reduced in a time- and dose-dependent manner (P<0.01). The intracellular Ca2+ imbalance and UPRE luciferase fluorescence intensity were increased in the AGE group compared with the control group (P<0.01). The mRNA levels of endoplasmic reticulum stress-related factors CHOP and XBP1 were significantly increased (P<0.01), and the protein expression levels of p-PERK, CHOP, and ATF4 were significantly increased (P<0.05). Compared with the AGE group, YSTLP effectively improved intracellular Ca2+ imbalance in HK-2 cells and decreased UPRE luciferase fluorescence intensity in a dose-dependent manner (P<0.01). It reduced the mRNA levels of endoplasmic reticulum stress-related factors CHOP and XBP1 (P<0.01) and the protein expression levels of intracellular p-PERK, CHOP, and ATF4 in a dose- and time-dependent manner (P<0.01). In animal experiments, the protein expression level of Bcl-2 was significantly reduced(P<0.01), and that of cleaved Caspase-3 and Bax was significantly increased in the model group compared with the control group (P<0.05). The protein expression level of Bcl-2 was dose-dependently elevated, and that of cleaved Caspase-3 and Bax was dose-dependently decreased in the YSTLP groups compared with the model group (P<0.01). Compared with the control group, the mRNA expression levels of CHOP and XBP1 were significantly elevated in the model group (P<0.05, P<0.01), and the protein expression levels of p-PERK, CHOP, and ATF4 were significantly increased (P<0.05). Compared with the model group, YSTLP significantly decreased the mRNA expression levels of CHOP and XBP1 (P<0.01) and the protein expression levels of p-PERK, CHOP, and ATF4 (P<0.01). ConclusionYSTLP can effectively inhibit endoplasmic reticulum stress and improve apoptosis of renal tubular epithelial cells, and its mechanism may be related to the regulation of the PERK/AFT4/CHOP pathway.

Objective:To investigate the effect and molecular mechanism of miR-15a-5p regulation Wnt signaling pathway in PQ-induced pulmonary fibrosis.Methods:The PQ-induced 16HBE cell model was constructed, high-throughput miRNA chip and RT-qPCR were used to screen for miR-15a-5p with significant differences. The experimental groups were as follows: NC group (normal control);no special treatment; PQ group: 50 μmol/L PQ treated cells for 72 h; miR-15a-5p group: 16HBE stable cell lines transfected with miR-15a-5p overexpressing lentivirus; miR-15a-5p+PQ group: Stable cell lines were treated with 50 μmol/L PQ for 72 h. The expression of Wnt pathway-related genes Wnt3α and β-catenin, fibroblast marker genes Collagen I, Vimentin and α SMA, epithelial marker genes Occludin and CK18 were detected by RT-qPCR and Western blot. The mice model of PQ-induced pulmonary fibrosis was constructed, and the protein expression and lung tissue injury were detected by Western blot, HE staining and immunohistochemistry. Data were expressed as mean ± standard deviation, and independent sample t-test was used to analyze the data between the two groups. Results:The expressions of Wnt3α, β-catenin, fibroblast marker genes Collagen I, Vimentin and α SMA significantly up-regulated in cell injury models ( P<0.05), the epithelial cell marker genes Occludin and CK18 significantly down-regulated ( P<0.05), overexpression of miR-15a-5p could inhibit the expression of Wnt3α and alleviated the EMT induced by PQ. In animal models, Wnt3α, β-catenin, fibroblast marker genes Collagen I, Vimentin and α SMA significantly increased ( P<0.01), the structure of lung tissue was disordered and fibrosis occurred, overexpression of miR-15a-5p inhibited the expression of Wnt3α protein ( P<0.05) and ameliorated lung tissue injury. Conclusions:miR-15a-5p ameliorates PQ-induced lung injury by modulating the Wnt3α/β-catenin signaling pathway, thereby inhibiting the development of pulmonary fibrosis.

Objective:To explore the relationship between stress coping styles and disability levels in patients with spinal cord injury (SCI) .Methods:Totally 300 SCI patients who were hospitalized in the Spinal Surgery Department of three Class Ⅲ Grade A hospitals in Anhui Province from March 2021 to February 2022 were selected by convenience sampling. Data were collected using a general information questionnaire, the Spinal Cord Lesion-related Coping Strategies Questionnaire (SCL-CSQ), and the WHO Disability Assessment Schedule (WHODAS 2.0). Spearman correlation analysis was used to examine the relationship between stress coping styles and disability levels, and multiple linear regression analysis was employed to identify factors influencing disability levels in these patients.Results:A total of 300 questionnaires were distributed, with 269 valid responses received, yielding an effective response rate of 89.67% (269/300). The total score of WHODAS 2.0 for the 269 patients was [91.00 (72.50, 104.00) ], with an item mean score of [2.53 (2.01, 2.89) ], and an average score rate of 59.86%, indicating a moderate to high level of disability. The average score rate for positive stress coping (facing, seeking support, rationalization) was 67.30%, while for negative stress coping (rejection and denial, fantasy, dependency and compromise), it was 64.48%. Negative stress coping was positively correlated with disability levels ( P<0.05), while positive stress coping was negatively correlated with disability levels ( P<0.05). Multiple linear regression analysis showed that occupation, American Spinal Injury Association classification, facing, rejection and denial, and dependency and compromise were factors influencing disability levels in SCI patients ( P<0.05), explaining 50.4% of the total variance in disability levels. Conclusions:The disability level of SCI patients is moderate to high, and stress coping style is an influencing factor. Healthcare professionals should help patients avoid controllable stressors, cultivate effective stress coping strategies, prevent helplessness, to shorten the time window for disability development, and improve patients' quality of life.

Cerebral hemorrhage accounts for about 10%-15% of all strokes, and its pathogenesis is complex. Currently, the main clinical treatment is mainly medical symptomatic treatment, including the use of antihypertensive drugs, hypoglycemic drugs, and hemostatic drugs, and surgical treatment is required in some cases, but there is still a lack of effective treatment. In recent years, traditional Chinese medicine and proprietary Chinese medicine have been widely accepted for their stable efficacy, high safety, and low cost. Rhei Radix et Rhizoma is one of the most commonly used herbal medicines for the treatment of cerebral hemorrhage. This paper summarizes the relevant literature on the treatment of cerebral hemorrhage with Rhei Radix et Rhizoma and finds that its active ingredients are mainly anthraquinones, such as emodin, Rhei Radix et Rhizoma acid, and Rhei Radix et Rhizoma phenol. The herbal formulas are Da Chengqitang, Shengdi Dahuangtang, Liangxue Tongyufang, and Naoxueshu oral liquid. The effects involve protecting the blood-brain barrier, promoting hematoma absorption, reducing inflammation levels, decreasing lactic acid accumulation at the bleeding site, and increasing the expression of brain-derived neurotrophic factors. The pathways involved include aquaporin 4 (AQP4), phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt), extracellular signal-regulated kinase 1/2 (ERK1/2), Toll-like receptor 4 (TLR4), nuclear transcription factor-κB (NF-κB), nuclear factor E2-related factor 2 (Nrf2), and Wnt3a/β-linked protein pathway. This paper summarizes the progress of clinical studies and animal experiments on the treatment of cerebral hemorrhage with active ingredients of Rhei Radix et Rhizoma and herbal compounds containing Rhei Radix et Rhizoma, so as to provide a reference for the treatment protocol of cerebral hemorrhage.

Objective:To investigate the risk factors of early neurological deterioration (END) in patients with minor ischemic stroke caused by large vessel occlusion (LVO) and the impact of rescue endovascular thromboectomy (REVT) on clinical outcomes of patients with END at discharge.Methods:Consecutive patients with acute minor ischemic stroke caused by LVO within 24 h of onset in the Third Affiliated Hospital, Soochow University from January 2021 to March 2023 were retrospectively enrolled. Minor ischemic stroke was defined as baseline National Institute of Health Stroke Scale (NIHSS) score ≤5 at admission. END was defined as an increase of ≥4 in the NIHSS score within 24 h after the best medical management. The modified Rankin Scale was used to evaluate the clinical outcomes of patients with END at discharge. 0-2 was defined as a good outcome. Multivariate logistic regression analysis was used to identify the independent risk factors for END and the impact of REVT on clinical outcomes in patients with END. Results:A total of 75 patients with minor ischemic stroke caused by LVO were included, of which 31 (41.3%) developed END and 13 (41.9%) underwent REVT after END. Multivariate logistic regression analysis showed that internal carotid artery occlusion was an independent risk factor for END (odds ratio 4.304, 95% confidence interval 1.213-15.270; P=0.024), and REVT was an independent protective factor for good outcomes in patients with END (odds ratio 0.068, 95% confidence interval 0.006-0.774; P=0.030). Conclusions:The incidence of END is higher in patients with minor ischemic stroke caused by LVO, and internal carotid artery occlusion is an independent risk factor for the occurrence of END. Providing REVT after END may improve the clinical outcomes of patients with END at discharge.

Objective:To investigate the diagnostic value of DDIT3 immunohistochemical antibody in myxoid liposarcoma.Methods:A total of 53 patients diagnosed with myxoid liposarcoma and with DDIT3 gene rearrangement detected by fluorescence in situ hybridization (FISH) from 2010 to 2022 in Beijing Jishuitan Hospital were enrolled as the case group, and 50 patients with other tumors that needed to be differentiated from myxoid liposarcoma during the same period were enrolled as the control group. The immunochemical (IHC) expression of DDIT3 was evaluated in all cases and the specificity and sensitivity in the diagnosis of myxoid liposarcoma were calculated. The correlation between IHC DDIT3 expression and FISH detection of DDIT3 gene rearrangement was analyzed.Results:Among the 53 cases of myxoid liposarcoma, thirty-one patients were males and twenty-two were females. The patients ranged in age from 11 to 74 years, with a median age of 51 and an average age of 49.4 years. The expression rate of IHC DDIT3 expression in 53 cases of myxoid liposarcoma was 100%. No expression was found or only scattered individual cell (<10%) expression was seen in a very few cases in the. control group. There was no significant correlation between the proportion and intensity of IHC and FISH DDIT3 positive cells or the partner gene.Conclusions:The sensitivity and specificity of DDIT3 immunohistochemical antibody in the diagnosis of myxoid liposarcoma are both 100%, which are consistent with the results of FISH. It can be used as a convenient and economical diagnostic tool for myxoid liposarcoma.

Objective To explore the ability of waist circumference (WC) to predict hypertension risk in overweight and non-overweight middle school students in Suzhou. Methods The height, weight,WC and blood pressure values of 963 students from 8 middle schools in Suzhou were collected by a combination of questionnaire survey and physical examination. Logistic regression analysis was applied to explore the correlation between WC and high blood pressure in middle school students. Results Logistic regression analysis showed that before and after adjusting for confounding factors, for every 1 cm change in WC, the risk of high blood pressure increased to 1.08 (1.03-1.14) and 1.07 (1.02-1.13) for non-overweight students, and 1.05 (1.02-1.09) and 1.05 (1.01-1.08) for overweight students, respectively. Conclusion There was a positive correlation between WC and high blood pressure in both non-overweight and overweight middle school students in Suzhou. The risk of high blood pressure was higher for non-overweight students than overweight students for every 1 cm WC change. Targeted intervention measures should be taken to reduce the prevalence rates of hypertension for middle school students.
