Asthma is a chronic inflammatory respiratory disease involving multiple cells and cellular components， characterized by recurrent episodes of wheezing， shortness of breath， chest tightness， and coughing， significantly impacting patients' quality of life. The phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway， as a crucial hub in intracellular signaling， is widely involved in the regulation of cell growth， proliferation， survival， metabolism， and a series of pathophysiological processes. Its regulatory role in the pathological progression of asthma is particularly significant， specifically in promoting airway inflammation， mediating epithelial mesenchymal transition， accelerating airway remodeling， regulating cell autophagy， inducing mucus hypersecretion， and influencing immune response balance. This study analyzed potential molecular targets of the PI3K/Akt pathway， including activators such as cysteine proteinase inhibitor 1（CST1）， found in inflammatory zone 1（FIZZ1） and free fatty acid receptor 1（FFAR1）， and inhibitors such as human β-defensin-3（hBD-3）， disintegrins， metalloproteinase 33（ADAM33） and interleukin-27（IL-27）， and initially revealed the potential molecular mechanisms of traditional Chinese medicine（TCM） in asthma intervention. Based on this， the authors systematically summarized the efficacy and specific mechanisms of TCM monomers， compounds， and external treatments for asthma by regulating the PI3K/Akt signaling pathway through literature review and analysis， aiming at establishing a robust foundation for the wide application and advanced development of TCM in asthma treatment， offering innovative insights for clinical research and drug development of asthma.

OBJECTIVE To explore the effect and mechanism of embryonic intervention with Zuogui pill on the glucose tolerance in offsprings of pregnant rats with gestational diabetes mellitus. METHODS Pregnant rats were randomly divided into blank group， model group， positive control group （insulin glargine）， Zuogui pill low-， medium- and high-dose groups （4.725， 9.45， 18.9 g/kg）. In addition to the blank group， streptozotocin was injected intraperitoneally to establish a gestational diabetes mellitus rat model. From day 6 to day 18 of pregnancy， each group was given relevant medicine and distilled water intragastrically， once a day. After 21 days of birth， the body weight and body length of offsprings were recorded， and the area under the curve （AUC） was calculated through a glucose tolerance test. After 22 days of birth， fasting blood glucose （FBG）， fasting insulin （FINS） levels in serum， insulin sensitivity index （ISI）， and homeostasis model assessment of insulin resistance （HOMA-IR） were measured， and the morphological structure of pancreatic tissue was observed. The protein spectrum of pancreatic tissue was analyzed by tandem mass tag-based proteomics， and protein and mRNA expression levels of apolipoprotein A1（ApoA1）， solute carrier family 27 member 1 （Slc27a1）， kininogen 1（Kng1） and sodium/potassium-transporting ATPase subunit alpha 2 （Atp1a2）， solute carrier family 7 member 5 （Slc7a5）， solute carrier family 3 member 2 （Slc3a2）， bile acid-coenzyme A： amino acid N- acyltransferase （Baat）， eukaryotic translation initiation factor 2 subunit gamma （Eif2s3） were detected. RESULTS Compared with the model group， the body weight， body length and ISI of offsprings in the positive control group and Zuogui pill medium-dose group were significantly increased （P＜0.05）， while the glucose tolerance and islet cell proliferation were significantly improved， and the AUC， FBG， FINS and HOMA-IR were significantly decreased （P＜0.05）. There were 88 potential target proteins for the embryonic intervention of Zuogui pill in offsprings of pregnant rats with gestational diabetes mellitus，involving multiple pathways such as peroxisome proliferator-activated receptor （PPAR）， cyclic guanosine monophosphate-protein kinase G （cGMP-PKG）， fat digestion and absorption， and bile secretion. The proteins closely related to glucose metabolism and insulin resistance mainly included ApoA1， Slc27a1， Kng1， Atp1a2， Slc7a5， Slc3a2， Baat， and Eif2s3. Among them， compared with the model group， protein and mRNA expressions of Slc7a5， Slc3a2， and Baat in the pancreatic tissues of pregnant rat offsprings in the Zuogui pill medium-dose group were significantly up-regulated （P＜0.05）； protein and mRNA expressions of ApoA1， Slc27a1， Kng1， Atp1a2 and Eif2s3 were all significantly down-regulated （P＜0.05）. CONCLUSIONS The intervention of Zuogui pill in the embryonic period on offsprings of pregnant rats with gestational diabetes mellitus can improve their blood glucose levels and pancreatic pathological morphology. The mechanism may be related to the upregulation of the expressions of Slc7a5， Slc3a2， and Baat and the down-regulation of ApoA1， Slc27a1， Kng1， Atp1a2 and Eif2s3 expressions in the PPAR， cGMP-PKG， fat digestion and absorption， and bile secretion pathways.

Background: In the Chinese coal industry, widespread blame avoidance behavior (BAB) greatly impacts coal mine accidents. Therefore, it is necessary to stop the BAB of coal mine managers and raise the management level of coal mine enterprises for the safe development of Chinese coal industry. Methods: Based on the semi-structured interviews and questionnaire surveys (20 middle-level managers in coal mines), this paper used the Grounded Theory and Nvivo Software qualitative research methodology to open, spindle, and selectively encode the interview data. Then, an index system of factors influencing BAB of coal mine managers was constructed. The influence degree, affected degree, centrality degree, cause degree of each influencing factor were calculated and the hierarchical model of influencing factors of BAB of coal mine managers was established by the DEMATEL-ISM method which is a decision support tool used to evaluate and analyze the interdependencies between influencing factors. Results: Index system of factors influencing BAB of coal mine managers included four levels and 12 influencing factors: individual, organizational, institutional environmental, and situational factors. The hierarchical model identified eight causal factors and four consequential factors, of which safety management (15.355), work attitude (14.380), and work group performance (14.281) in the top three of the centrality rankings are the key factors affecting the avoidance behavior of coal mine managers; A 3-level multilevel structure was constructed to reflect the interactions among the factors influencing the BAB of coal mine managers in terms of direct, indirect, and root causes, and corresponding improvement measures were proposed. Conclusion This study offers a theoretical complement and practical guidance for stopping BAB of coal mine managers.

Objective:To compare the performance of 11 glomerular filtration rate(GFR)equations in Chinese elderly hospitalized patients using dynamic renal imaging as the reference standard.Methods:The retrospective study involved patients aged 60 years and older who were admitted to Beijing Hospital between January, 2017, and January 2020.Glomerular filtration rate(GFR)was assessed through dynamic renal imaging for all participants.Estimated GFR(eGFR)was calculated using various equations based on serum creatinine and/or cystatin C levels, including All Age Spectrum(FAS), Berlin Initiative Study(BIS), Chronic Kidney Disease Epidemiology Collaboration(CKD-EPI), Modification of Diet in Renal Disease Study(MDRD), MDRD in China(MDRDc), and Xiangya..Results:A total of 691 patients, of which 383 were males, with an age range of 60 to 90 years(mean age 71.9±7.7 years), were included in the study.Among the different equations used to estimate glomerular filtration rate(GFR)in ml·min -1·1.73m -2, the smallest deviations were observed with FAScys(2.48), FAScr-cys(3.07), CKD-EPIcys(4.20), and BIScr-cys(7.42).Conversely, the most accurate estimations were found with BIScr-cys(10.38), FAScr-cys(11.94), FAScys(12.08), CKD-EPIcr-cys(13.21), and CKD-EPIcys(13.51).The highest P30 values, indicating the proportion of estimates within 30% of the true GFR, were achieved by FAScr-cys(68.97%), FAScys(68.96%), CKD-EPIcys(63.22%), and BIScr-cys(61.67%).The equations with the lowest root mean square errors were BIScr-cys(9.73), CKD-EPIcr-cys(10.98), FAScr-cys(11.27), CKD-EPIcys(11.52), and FAScys(11.53).Specifically, the FAS equation showed higher accuracy in men, while BIScr-cys and CKD-EPIcys were more accurate in women.Among patients with chronic kidney disease(CKD), the P30 values for BIScr-cys, FAScys, and FAScr-cys were 86.96%, 83.33%, and 80.95% respectively.Notably, for patients with mGFR ≥ 30 ml/min, MDRDc overestimated GFR the most, whereas for patients with mGFR<30 ml/min, Xiangya exhibited the most significant overestimation of GFR. Conclusions:Among the equations tested, BIScr-cys, FAScys, and FAScr-cys demonstrated the highest accuracy and are therefore recommended for use in Chinese elderly hospitalized patients.

Oxidative stress plays a key role in acute kidney injury (AKI). 8-Oxo-7,8-dihydroguanosine (8-oxo-Gsn) can reflect the overall level of oxidative stress in the body. The levels of urinary 8-oxo-Gsn and renal function-related indicators in 62 patients who underwent video-assisted thoracic surgery (VATS) or open-chest surgery were measured during the perioperative period. The results showed that urinary 8-oxo-Gsn increased 24 hours after surgery and decreased 48 hours after surgery as the condition improved. In 10 patients with severe complications, urinary 8-oxo-Gsn continued to rise. The level of urinary 8-oxo-Gsn in the VATS group recovered faster than that in the open-chest surgery group ( P<0.05). There was a certain correlation between the level of urinary 8-oxo-Gsn and postoperative renal injury in thoracic surgery, suggesting that RNA oxidative stress may play an important role in the pathogenesis of surgery-related AKI.

Objective To explore the effects of astaxanthin on pressure injury wounds.Methods In vitro experiment:Fibroblasts were treated with different concentrations of astaxanthin and their proliferation activity was detected by CCK-8 assay.Subsequently,fibroblasts were induced by hypoxia/reoxygenation,and the optimal concentration of astaxanthin was administered.Then the intracellular reactive oxygen species(ROS)level was detected by DHE fluorescent probes and the mRNA expression level of TNF-α,IL-1β,IL-6,IL-10,TGF-β was evaluated by RT qPCR.In vivo experiment:to construct a pressure injury model,two circular magnets were symmetrically adsorbed on both sides of the mouse skin for 5 hours everyday.Subsequently,equal amounts of physiological saline,low-dose astaxanthin(10 mg/kg),and high-dose astaxanthin(20 mg/kg)were administered by gavage in groups.Wound images were taken regularly.After 7-day treatment,wound healing rates were counted and wound tissues were collected for histopathological staining.Results In vitro,the fluorescence intensity of DHE in the astaxanthin groups were reduced dramatically.The relative mRNA expression level of TNF-α,IL-1β,IL-6 in the astaxanthin group declined,and the level of TGF-β and IL-10 mRNA increased significantly(P<0.05).In vivo,the wound healing rate and the level of TGF-β,IL-10 in high-dose astaxanthin group increased significantly.The ROS content and the level of TNF-α,IL-1β and IL-6 dropped markedly in astaxanthin groups(P<0.05).Conclusions Astaxanthin can significanlty alleviate oxidative stress,mitigate inflammation,thus exerting a protective effect on pressure injury wounds.

Objective:To investigate the clinical diagnosis, treatment, and genetic variations of neonates with congenital hyperinsulinism (CHI).Methods:The clinical data of CHI newborns admitted to the Provincial Hospital Affiliated to Shandong First Medical University from September 2018 to April 2022 were retrospectively analyzed.Results:Four cases of CHI were included, three of whom were full-term infants and all were macrosomic, while one was a premature infant. One infant was born to a mother with gestational diabetes mellitus, and 1 had a family history of hypoglycemia. All the 4 patients presented with weak response, 3 with drowsiness, 1 with hypotonia and 1 with convulsions. Cranial MRI indicated abnormal signals in the occipital lobe cortex in 1 case. Gene sequencing revealed homozygous variation c.799C>G in KCNJ11 gene for 1 case, and heterozygous variations c.4477C>T, c.3540C>G, c.683G>A and c.4536C>A in ABCC8 gene for 3 cases respectively and all these variations were identified as pathogenic mutations. Notably, the c.799C>G variant in KCNJ11 gene as well as the c.3540C>G and c.4536C>A variants in ABCC8 gene were reported for the first time. Among infants with ABCC8 gene variations, two showed no response to diazoxide treatment while one patient with KCNJ11 gene variation responded effectively. The parents of the patient with hypoglycemic brain injury gave up treatment. Three other cases were discharged from hospital after improvement and followed up to 1 year old. 2 patients had stable blood glucose after ceasing medication, and 1 patient still required intermittent oral glucose to maintain normal blood glucose level.Conclusions:CHI can lead to hypoglycemic brain injury. Clinically, infants large for gestational age or with a family history of diabetes and hypoglycemia should be monitored for blood glucose early after birth, to identify CHI as early as possible and actively treat it. Different gene variants have different therapeutic responses.
