OBJECTIVE To investigate the potential mechanism by which Juanxiao decoction improves bronchial asthma （hereinafter referred to as “asthma”） based on the nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 （NLRP3） inflammasome signaling pathway. METHODS Female SD rats were randomly assigned to normal group， model group and Juanxiao decoction low-， medium- and high-dose groups （0.36， 0.72 and 1.44 g/kg， calculated based on crude drug weight）， as well as positive control group （Dexamethasone acetate tablets， 0.2 mg/kg）， with 10 rats in each group. Except for the normal group， asthma models were established in the remaining groups via intraperitoneal injection of ovalbumin combined with aluminum hydroxide， followed by nebulized inhalation of ovalbumin. On day 14 of the experiment， rats in each group received intragastric administration of the corresponding solution or normal saline， once a day， for 7 consecutive days. Following the final administration， the following parameters were measured in each group： lung function indexes （forced vital capacity， forced expiratory volume in 0.3 second， peak expiratory flow）， serum levels of inflammatory markers （interleukin-1β， interleukin- 18）， and the percentages of inflammatory cells （lymphocytes， eosinophils， neutrophils） in bronchoalveolar lavage fluid. Histopathological changes in lung tissue were observed， and the protein and mRNA expressions of nuclear factor-kappa B （NF- κB）， NLRP3 and caspase-1 in lung tissue were detected. RESULTS Compared with the normal group， pathological changes such as alveolar wall thickening and inflammatory cell infiltration were observed in rats in the model group. All pulmonary function indicators were significantly reduced in rats in the model group and the administration groups. The levels of inflammatory markers， the percentages of inflammatory cells， and the protein and mRNA expressions of NF-κB， NLRP3 and caspase-1 were significantly elevated or up-regulated （P＜0.05）. Compared with the model group， pathological changes in rats in each dosage group of Juanxiao decoction were significantly alleviated， and all quantitative indicators showed dose-dependent improvements （P＜0.05）. CONCLUSIONS Juanxiao decoction can reduce airway inflammatory responses in asthmatic rats， alleviate lung function impairment， and improve pathological changes such as inflammatory cell infiltration. Those effects may be related to the inhibition of the NLRP3 inflammasome signaling pathway.

Objective To investigate the levels of gross α and gross β activities in different water types within a 40-kilometer radius around the Zhangzhou Nuclear Power Plant prior to its operation. Methods In 2018, drinking water samples were collected from the area surrounding the nuclear power plant during both the wet and dry seasons, including source water, treated water, tap water, and well water. The gross α and gross β activity concentrations were measured using a low-background α/β counter, followed by statistical analysis. Results A total of 80 water samples from different sources around the Zhangzhou Nuclear Power Plant were collected. The average gross α and gross β activity concentrations during the wet season were (0.110 ± 0.036) Bq/L and (0.643 ± 0.028) Bq/L, respectively, while those during the dry season were (0.124 ± 0.032) Bq/L and (0.624 ± 0.026) Bq/L, respectively. There were no significant differences in the gross α and gross β activity concentrations between the wet and dry seasons for the overall sample set (P > 0.05). However, there were statistically significant differences in the gross α and gross β activity concentrations between the wet and dry seasons for source water and well water (Z_wet = −2.005, −2.123; Z_dry = −1.943, −3.090; P < 0.05). Conclusion The radioactivity levels in different water types within various ranges around the Zhangzhou Nuclear Power Plant before its operation were determined. The measured activity concentrations were at the same level as those from previous investigations in other regions of Fujian Province.

ObjectiveTo investigate the mechanism of Shenkang injection in delaying diabetic kidney disease by regulating endoplasmic reticulum stress and attenuating podocyte apoptosis through the Glucose regulated protein 78 （ GRP78 ） / transcription factor C / EBP homologous protein （ CHOP ） signaling pathway （GRP78/CHOP） signaling pathway. MethodsFor the animal experiment， 10 12-week-old db/m mice were selected as a normal group， and 30 12-week-old db/db mice were randomly divided into a model group， a Shenkang injection group （15.6 mL·kg^-1）， and a dapagliflozin group （1.6 mg·kg^-1）. To observe the general condition of mice， fasting blood glucose， urinary albumin/urine creatinine （ACR）， and 24 h urine protein quantification were detected in each group before drug administration. After 12 weeks of drug treatment， mice were tested for fasting blood glucose， total cholesterol （TC）， triglyceride （TG）， low-density cholesterol （LDL）， ACR， 24 h urine protein quantification， blood creatinine （SCr）， and blood urea （UREA）. Hematoxylin-eosin （HE） staining， periodic acid-Schiff （PAS） staining， and transmission electron microscopy were used to observe the pathologic morphology in renal tissue. Immunohistochemistry was used to detect the expressions of nephroprotective marker protein （Nephrin）， glucose-regulated protein 78 （GRP78）， CCAAT/enhancer-binding protein homologous protein （CHOP）， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） in renal tissue. Western blot was used to detect the expressions of GRP78， CHOP， Bcl-2， Bax， and Nephrin proteins， and Real-time polymerase chain reaction （Real-time PCR） was employed to detect the expressions of Nephrin， GRP78， CHOP， Bcl-2， and Bax mRNAs in renal tissue. ResultsBefore drug administration， compared with those in the normal group， the body mass of db/db mice was significantly increased， and blood glucose， 24 h urine protein quantification， and ACR were significantly elevated in the Shenkang injection group and Dapagliflozin group （P<0.01）. After 12 weeks of administration， compared with those in the model group， the general state of mice in the Shenkang injection group was significantly improved， and the body mass was decreased. The blood glucose was significantly reduced （P<0.01）， and blood lipids TC， TG， and LDL were significantly decreased （P<0.05， P<0.01）. The 24 h urine protein quantification and ACR were significantly decreased （P<0.05）， and SCr and UREA were significantly reduced （P<0.01）. Compared with those of the model group， the pathologic results of the Shenkang injection group showed that proliferation of mesangial cells， reduction of inflammatory cell infiltration， and alleviation of renal tubular vacuolization and podocyte damage were observed in renal tissue of mice. Electron microscopy showed that fusion of the pedicle protruding and thickening of the basement membrane were reduced. Immunohistochemistry results showed that the expressions of GRP78， CHOP， and Bax proteins were significantly reduced （P<0.01）， and the expressions of Nephrin and Bcl-2 proteins were significantly increased （P<0.01） in renal tissue of the Shenkang injection group. Western blot results showed that the expressions of Nephrin and Bcl-2 in the Shenkang injection group were significantly increased （P<0.05， P<0.01）， and the expressions of GRP78， CHOP， and Bax proteins were significantly decreased （P<0.05， P<0.01）. Real-time PCR results showed that the expressions of GRP78， CHOP， and Bax mRNAs were down regulated in the Shenkang injection group （P<0.01）， and the expressions of Nephrin and Bcl-2 mRNAs were up regulated （P<0.01）. ConclusionShenkang injection inhibits endoplasmic reticulum stress response and podocyte apoptosis by regulating the GRP78/CHOP signaling pathway， which in turn ensures the integrity of glomerular filtration barrier， reduces the occurrence of proteinuria， improves renal function， and thus delays the progression of diabetic kidney disease.

Objective To investigate the differences of cerebral vascular morphology and serum indexes between patients with vascular cognitive impairment no dementia(VCIND)and cognitively normal cerebral vascular disease.Methods A total of 100 VCIND patients hospitalized in Quzhou Hospital of Zhejiang Medical and Health Group from June 2023 to September 2024 were included in experimental group,and 100 cognitively normal patients with cerebral vascular disease hospitalized during the same period were included in control group.Cerebral artery extension and dilation,cerebrovascular stenosis,collateral circulation establishment,inflammatory factors and lipid metabolism indexes were compared between two groups by means of cerebrovascular angiography and serum examination.The relationship between the severity of cognitive impairment and the vascular lesion of different responsibility was also explored.Results The rate of cerebral artery extension and dilation,rate of vascular stenosis in experimental group were higher than those in control group,and the rate of collateral circulation establishment was lower than that in control group(P＜0.05).The levels of interleukin-6,interleukin-1 β,tumor necrosis factor-α,total cholesterol,low density lipoprotein,apolipoprotein B and lipoprotein(a)in experimental group were significantly higher than those in control group,level of high density lipoprotein was lower than that in control group(P＜0.05).In experimental group,there were 20 cases of anterior cerebral artery vascular disease,22 cases of middle cerebral artery vascular disease,26 cases of posterior cerebral artery vascular disease,32 cases of vertebrobasilar artery vascular disease.There were no significant differences in the scores of mini-mental state examination,Montreal cognitive assessment and Hachinski ischemic scale among patients with different responsible vascular diseases(P＞0.05).Conclusion Patients with cerebral artery extension and dilation,cerebral artery stenosis,no establishment of collateral circulation,inflammatory response and abnormal lipid metabolism were high-risk groups for VCIND.Such patients need early cognitive intervention to prevent VCIND occurrence.

Objective To investigate the impact of serine/threonine-protein kinase 1(AKT1)-mediated autophagy in hepatocellular carcinoma(HCC)cells on their sensitivity to 125I seed irradiation.Methods ① iProX database and STRING12.0 website were utilized to analyze the proteomic data of HCC before and after 125I seed irradiation to explore the differentially expressed proteins and associated functional connections.Meanwhile,The Cancer Genomics Atlas(TCGA)database was employed to analyze the relationship between AKT1 expression level and the survival of HCC patients.② Human HCC cell lines HUH7 and Hep3B were exposed to continuous irradiation from 125I radioactive seeds with an initial apparent activity of 0.8 mCi per seed for approximately 120 h,accumulating a total dose of 8 Gy,while the control cells were cultured under normal condition for 120 h.③ Autophagy inhibitor,chloroquine(CQ)and inducer,rapamycin(RAPA)were used to treat the HCC cells respectively to establish the CQ group and the RAPA group.The lentiviral transfection technique was employed to construct the HCC cells with overexpressed AKT1,namely the AKT1 group.The HCC cells treated in the same way were continuously irradiated with 125I seeds for 120 h to construct the CQ+125I group,the RAPA+125I group,and the AKT1+125I group.④The changes in microtubule-associated protein light chain 3(LC3),p62,AKT1 and p-AKT1 were detected by Western blotting.Cell immunofluorescence assay was employed to observe the expression of autophagy related proteins,such as LC3.The colony forming ability and apoptotic rate were detected with plate cloning assay and flow cytometry.Results ① Continuous irradiation with 125I seeds resulted in decreased expression of p62 and increased ratio of LC3Ⅱ/LC3Ⅰ(P＜0.05)when compared with the negative control(NC)group.Immunofluorescence assay revealed more green fluorescence spots of LC3.When compared with the 125I group,the CQ+125I group had significantly increased expression of p62(P＜0.01),decreased ratio of LC3Ⅱ/LC3Ⅰ(P＜0.01),lower apoptotic rate(P＜0.01),and more colony formations(P＜0.01).In contrast,the results in the RAPA+125I group were opposite to those of the CQ+125I group.② Analysis on the iProX database showed that the expression of AKT1 was decreased in the irradiated group,and analysis on the TCGA database indicated that high expression of AKT1 predicted a poor prognosis for HCC patients(P＜0.01).③After irradiation with 125I seeds,the expression of AKT1 at both the RNA and protein levels was decreased in the 125I group(P＜0.01).After overexpression of AKT1,the level of autophagy was decreased(P＜0.05).Irradiation of HCC cells with overexpressed AKT1 using 125I seeds could partially restore the level of autophagy.In the AKT1+125I group,the expression of AKT1,pAKT1 and p62 were all decreased,and the ratio of LC3Ⅱ/LC3Ⅰwas increased than the AKT1 group(P＜0.05).④ The apoptotic rate of the AKT1+125I group was lower than that of the 125I group(P＜0.05)and higher than that in the AKT1 group(P＜0.05).In HUH7 cells,the clonogenic ability of the AKT1+125I group was higher than that of the 125I group(P＜0.05).In Hep3B cells,the clonogenic ability of the AKT1+125I group was higher than that of the 125I group,and the clonogenic ability of the AKT1 group was higher than that of the NC group(P＜0.05).Conclusion 125I seed irradiation induce lethal autophagy in HCC cells by reducing the expression of AKT1,providing a new theoretical basis for the implantation of 125I radioactive seeds in the treatment of HCC.

This paper reports the general conditions, diagnostic and therapeutic processes, and current status of 10 patients diagnosed with HAE at the First Affiliated Hospital of Kunming Medical University between October 2022 and March 2025. Eight cases were type 1 and two were type 2. Patient ages ranged from 17 to 55 years, with a median age at diagnosis of 36 years and a median age at onset of 17 years. The median diagnostic delay was 13.5 years, with the longest delay being 40 years and the shortest 4 years. Clinical presentations were diverse, primarily involving recurrent skin and/or mucosal edema. All 10 patients presented with upper respiratory tract mucosal edema, five cases exhibited prominent gastrointestinal edema accompanied by abdominal pain and distension. By reporting the clinical characteristics of 10 confirmed cases of HAE, this paper aims to provide a reference for clinicians in their diagnosis and treatment.

ObjectiveTo explore the mechanism of Yishen Huashi granules in alleviating renal tubular epithelial cell injury and relieving diabetic kidney disease by regulating the mitogen-activated protein kinase （MAPK） signaling pathway. MethodsThe db/db mice of 12 weeks old were randomly assigned into model ， dapagliflozin （1.6 mg·kg^-1）， and Yishen Huashi granules （4.7 g·kg^-1）， and db/m mice were used as the control group. The general conditions of mice were observed， and fasting blood glucose and 24-h urinary protein and albumin-to-creatinine ratio （ACR） were measured at weeks 0 and 12 of administration. After 12 weeks of treatment， the levels of serum creatinine （SCr）， blood urea （UREA）， triglycerides （TG）， total cholesterol （TC）， and low density lipoprotein （LDL） were measured. The pathological changes in the renal tissue were observed by hematoxylin-eosin （HE） staining， Periodic acid-Schiff （PAS） staining， Mallory staining， and transmission electron microscopy. Real-time PCR was employed to determine the mRNA levels of monocyte chemotactic protein-1 （MCP-1） and CC chemokine receptor-2 （CCR2） in the renal tissue of mice. The immunohistochemical assay was employed to examine the expression of p38， phospho-p38 （p-p38）， MCP-1， and CCR2 in the renal tissue of mice. Western blotting was employed to measure the protein levels of p-p38， p38， MCP-1， and CCR2 in the renal tissue of mice.HK-2 cells cultured in vitro were grouped as follows： negative control， high glucose（30 mmol·L^-1）， Yishen Huashi granule-containing serum， and SB203580. After 48 h of cell culture in each group， RNA were extracted and the levels of MCP-1， and CCR2 mRNA were determined by Real-time PCR，proteins were extracted and the levels of p38， p-p38， MCP-1， and CCR2 were determined by Western blot. ResultsThe in vivo experiments showed that before treatment， other groups had higher body weight， blood glucose level， 24 h urinary protein， and ACR than the control group （P<0.05，P<0.01）. After 12 weeks of treatment， compared with the model group， the Yishen Huashi granules group showed improved general conditions， a decreasing trend in body weight， lowered levels of blood glucose， 24-h urinary protein， and ACR （P<0.01）， reduced SCr and UREA （P<0.01）， and declined levels of TC， TG， and LDL （P<0.05，P<0.01）. Compared with the model group， the Yishen Huashi granules group showed alleviated damage and interstitial fibrosis in the renal tissue as well as reductions in glomerular foot process fusion and basement membrane thickening. Moreover， the Yishen Huashi granules group showed down-regulated mRNA levels of MCP-1 and CCR2 （P<0.01）， reduced positive expression of p-p38， MCP-1， and CCR2 （P<0.01）， and down-regulated protein levels of p-p38/p38， MCP-1， and CCR2 （P<0.05） in the renal tissue. The cell experiment showed that compared with the high glucose group， the Yishen Huashi granule-containing serum group showcased down-regulated mRNA levels of MCP-1 and CCR2 （P<0.01） and down-regulated protein levels of p-p38/p38， MCP-1， and CCR2（P<0.05，P<0.01）. ConclusionYishen Huashi granules can regulate glucose-lipid metabolism， reduce 24 h urinary protein and ACR， improve the renal function， alleviate the renal tubule injury caused by high glucose， and protect renal tubule epithelial cells in db/db mice by reducing MCP-1/CCR2 activation via the p38 MAPK signaling pathway.

Objective To explore the expression changes of Galanin,Obestatin and Apelin-12 in the serum of Gastric Cancer(GC)patients and their correlation with Helicobacter pylori(Hp)infection.Methods 92 GC patients admitted to Tianmen First People's Hospital Affiliated to Wuhan University of Science and Technology from December 2021 to December 2023 were re-garded as the GC group,and a total of 76 age-and sex-matched non-GC(gastritis)patients were selected as control group.The 13C breath test method was used to detect Hp infection in patients.Basedon the test results,Hp infected GC patients were separat-ed into grade Ⅰ infection group(n=23),grade Ⅱ infection group(n=29)and grade Ⅲ infection group(n=26).Enzyme linked im-munosorbent assay(ELISA)was applied to detect serum levels of Galanin,Obestatin,Apelin-12 and inflammatory factors.Pear-son's method was used to analyze the correlation between serum levels of Galanin,Obestatin and Apelin-12 and Hp infection in GC patients.Receiver operating characteristic(ROC)curve was applied to evaluate the diagnostic value of serum Galanin,Obestatin and Apelin-12 for GC.Results The Hp positive rate in the GC group was greatly higher than that in the control group(39.47%vs 84.78%),and the differences was statistically significant(χ2=37.214,P<0.001).The serum Galanin level in GC group(19.69±7.23pg/ml)was lower than that in control group(32.73±12.45pg/ml),the level of Obestatin,apelin-12(40.46±11.78ng/ml,323.09±59.25ng/L)were higher those that of the control group(26.15±8.27ng/ml,264.72±40.96ng/l),and the differences were statistically significant(t=8.468,8.926,7.271,all P<0.05),and their levels were related to TNM staging and lymph node metastasis(t=2.963～12.070,all P<0.05).Comparison of serum Galanin,Obestatin and Apelin-12 levels between the non-infected group and theⅠ,ⅡandⅢ grade infection group showed statistically significant differences(F=26.594,38.245,13.545,all P<0.05).Pearson correnlation analysis showed that serum Galanin levels were negatively correlated with DOB values and TNF-α,IL-1β and IL-6 levels(r=-0.477～-0.387,all P<0.001),Obestatin and Apelin-12 levels were positively correlated with DOB values and TNF-α,IL-1β,IL-6 levels(r=0.389～0.453,all P<0.001).The AUC(95%CI)of serum Galanin,Obestatin and Apelin-12 levels for single and combined diagnosis of GC were 0.853(0.790～0.903),0.809(0.741～0.865),0.803(0.735～0.861)and 0.925(0.874～0.960),respectively.The combined diagnostic efficacy superior to the individual diagnosis of Galanin,Obestatin,and Apelin-12,and the differences were statistically significant(Z=2.237,3.719,3.913,all P<0.05).Conclusion The low expression of Galanin and high expression of Obestatin and Apelin-12 in serum of GC patients are closely related to Hp infection,and their combination has certain diagnostic value for GC.

Objective:To explore the correlation between nurses' electronic health literacy and their health education competence.Methods:A convenience sampling method was used to select nurses from 24 secondary and tertiary hospitals in Jincheng for the study from July to August 2022. The Mobile-e Health Literacy Scale and the Nurse Health Education Competence Self-assessment Scale were used to survey the subjects. Pearson correlation analysis was performed to analyze the correlation between nurses' electronic health literacy and their health education competence. Canonical correlation analysis was employed to build a standardized canonical correlation model, conduct canonical structure analysis, and canonical redundancy analysis to explore the relationship between electronic health literacy and health education competence in nurses.Results:A total of 705 questionnaires were distributed, 74 were excluded due to short response times (<120 seconds), regular responses, or incorrect fillings, leaving 631 valid questionnaires, with an effective response rate of 89.5%. The total score of the Mobile-e Health Literacy Scale for 631 nurses was (50.40±8.75), with scores of (12.69±2.41) for self-perception, (21.35±3.70) for information acquisition, and (16.36±3.29) for interaction judgment. The total score for the Nurse Health Education Competence Self-assessment Scale was (366.32±57.51), with subscale scores of (29.71±4.77) for knowledge and experience, (95.65±14.20) for comprehensive quality, and (240.97±40.85) for skills and abilities. The total score of electronic health literacy and the scores of each dimension were positively correlated with the scores of each subscale of health education competence ( P<0.01). Canonical correlation analysis identified three pairs of canonical variables, with correlation coefficients of 0.750, 0.279, and 0.067 for the first, second, and third pairs, respectively. The correlation coefficients of the first and second pairs were statistically significant ( P<0.01). Nurses' electronic health literacy was primarily determined by interaction judgment ( r=-0.982), while health education competence was primarily determined by skills and abilities ( r=-0.995) . Conclusions:There is a positive correlation between nurses' electronic health literacy and health education competence. Enhancing nurses' electronic health literacy is of significant importance for improving their health education competence.
