Diabetic nephropathy （DN） is one of the most common and severe microvascular complications of diabetes， with a complex pathogenesis involving immune inflammatory responses， oxidative stress， apoptosis， glomerulosclerosis， renal interstitial fibrosis， and other pathological processes. In recent years， numerous animal or cell model experiments have revealed that the transforming growth factor-β （TGF-β）/mothers against decapentaplegic homolog （Smad）， phosphoinositide 3-kinase （PI3K）/ protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， mitogen-activated protein kinase （MAPK）， AMP-activated protein kinase （AMPK）， nuclear factor-κB （NF-κB）， Janus kinase （JAK）/signal transducer and activator of transcription （STAT）， neurogenic locus notch homolog protein （Notch）， nuclear factor E₂-related factor 2 （Nrf2）， secretory glycoprotein （Wnt）/β-catenin， and other classical signaling pathways play important roles in the occurrence and development of DN. Traditional Chinese medicines， as natural drugs， possess characteristics such as multiple components， multiple targets， and few adverse reactions， demonstrating unique advantages in regulating the aforementioned signaling pathways and improving renal pathological changes. This review summarized recent research progress on the intervention of DN through the regulation of the aforementioned signaling pathways by single compounds and formulas of traditional Chinese medicine， focusing on their mechanisms of action in regulating immune inflammatory responses， inhibiting renal fibrosis， oxidative stress， improving metabolic disorders， and other aspects. The aim is to provide theoretical references for a deeper understanding of the modern pharmacological basis and clinical application of traditional Chinese medicine in the treatment of DN.

Objective: To evaluate the clinical efficacy of a novel autologous blood recovery device during the weaning process from extracorporeal membrane oxygenation (ECMO). Methods: A total of 16 patients who received ECMO support and underwent blood recovery during the weaning process from January 2022 to September 2024 at our hospital were included in the experimental group. In contrast, 58 patients who did not receive blood recovery during the weaning process were assigned to the control group. Transfusion components, costs, and changes in routine blood tests and coagulation functions were compared between the two groups from the day of weaning until 48 hours post-weaning. Results: Significant differences were observed in the volumes of red blood cell transfusions, plasma transfusions, and transfusion costs between the two groups from the day of weaning to 48 hours post-weaning (P<0.05). Additionally, in the experimental group, significant differences were noted in hemoglobin (Hb), platelet (Plt), and activated partial thromboplastin time (APTT) results when comparing values before and after extubation (P<0.05). Conclusion: The application of a novel autologous blood recovery device during ECMO weaning reduces patient costs, minimizes wastage of autologous blood, decreases reliance on exogenous blood transfusions, and mitigates the risks associated with allogeneic blood transfusion. This approach merits further promotion for clinical use.

In recent years,a growing body of research has demonstrated that acupuncture can be used to effectively treat a diverse range of diseases,including functional gastrointestinal disorders,cardiovascular diseases,as well as anxiety and depression,through the modulation of the paraventricular hypothalamic nucleus(PVN).Acupuncture may exert its therapeutic effect either by modulating specific neurons within the PVN,such as corticotropin releasing hormone(CRH)neurons,or by regulating the release of hormones,such as oxytocin(OXT)and vasopressin(VP),and the activity of neural circuits associated with the PVN.This review summarizes the mechanisms by which PVN is involved in acupuncture treatment,including its regulatory mechanisms in gastrointestinal diseases,cardiovascular diseases,and negative emotions and pain.Future research should be conducted to further explore the precise mechanisms by which acupuncture regulates PVN to treat diseases,focusing on clarifying the specific processes of signaling pathway transduction,and exploring the specific effects of acupunture of different acupoint combinations and stimulation frequencies and intensity on PVN.

ObjectiveExploring the role of microRNA126 （miRNA126） in chronic kidney disease combined with atherosclerosis （CKD AS） by regulating the phosphatidylinositol-3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway and the mechanism of Shenshuai Xiezhuo decoction in the intervention of CKD AS rats with 5/6 nephrectomy combined with high-fat feeding. MethodA total of 60 SD rats were randomly divided into sham operation group， model group， losartan group， and low， medium， and high dose groups of Shenshuai Xiezhuo decoction. The CKD AS rat model was established by 5/6 nephrectomy combined with high-fat feeding for 10 weeks. The low， medium， and high dose groups （6.0， 12.0， 24.0 g·kg^-1·d^-1） of Shenshuai Xiezhuo decoction and the losartan group （20 mg·kg^-1·d^-1） were gavaged， and the corresponding intervention was carried out for eight weeks. Then， the rats were killed， and samples were collected for corresponding detection. Fully automated biochemical analyzers were used to detect kidney function and blood lipids in rats： blood creatinine （SCr）， blood urea nitrogen （BUN）， total cholesterol （TC）， triglyceride （TG）， and low-density lipoprotein cholesterol （LDL-C） levels. Hematoxylin-eosin （HE） and Masson staining of aortic tissue and pathological observation under a light microscope were carried out， and autophagosomes and autophagy lysosomes were observed by transmission electron microscopy. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to determine the mRNA levels of miRNA126， PI3K， Akt， and mTOR in rats， and Western blot was used to determine the protein expression levels of phosphorylated （p）-PI3K， PI3K， p-Akt， Akt， p -mTOR， mTOR， benzyl chloride 1 （Beclin-1）， and microtubule-associated protein light chain 3Ⅱ/Ⅰ （LC3Ⅱ/LC3Ⅰ）. ResultCompared with the sham operation group， the serum SCr， BUN， TC， TG， and LDL-C in the model group were significantly increased （P<0.01）. Compared with the model group， the SCr， BUN， TC， TG， and LDL-C were decreased in the losartan group and low， medium， and high dose groups of Shenshuai Xiezhuo decoction （P<0.05）. Compared with the sham operation group， thickening plaques， infiltration of mononuclear macrophages， a small number of foam cells， disordered arrangement of smooth muscle fibers in the tunica media， and increased collagen fibers were observed in the model group， and the lesions in the losartan group and Shenshuai Xiezhuo decoction groups were alleviated compared with those in the model group. Compared with the model group， the number of autophagosomes and autophagy lysosomes increased in the medium and high dose groups of Shenshuai Xiezhuo decoction. Compared with the sham operation group， the expression of miRNA126 in the aortic tissue of the model group was significantly decreased （P<0.01）， and the mRNA expressions of PI3K， Akt， and mTOR were significantly increased （P<0.01）. Compared with the model group， the expression of miRNA126 in the aortic tissue of rats in high， medium， and low dose groups of Shenshuai Xiezhuo decoction and losartan group was significantly increased （P<0.01）， while the mRNA expressions of PI3K， Akt， and mTOR were significantly decreased （P<0.01）. Compared with the sham operation group， the protein expressions of p-PI3K， PI3K， p-Akt， Akt， p-mTOR， and mTOR in the model group were significantly increased （P<0.01）， while the protein levels of Beclin-1， LC3Ⅰ， and LC3Ⅱ were significantly decreased （P<0.01）. Compared with the model group， the protein expressions of p-PI3K， PI3K， p-Akt， Akt， p-mTOR， and mTOR in the losartan group and low， medium， and high dose groups of Shenshuai Xiezhuo decoction were decreased （P<0.05）， while the protein levels of Beclin-1 and LC3Ⅱ/LC3Ⅰ were increased （P<0.05）. ConclusionThe expression of miRNA126 is decreased in the aortic tissue of CKD AS rats， and the PI3K/Akt/mTOR pathway is activated to inhibit autophagy flux. Shenshuai Xiezhuo decoction regulates the PI3K/Akt/mTOR signaling pathway through miRNA126， restores the autophagy of aortic endothelial cells， protects the damage of CKD vessels， reduces the formation of As plaques， and slows the development of cardiovascular complications.

Objective To explore the effect of the orthokeratology lenses on the control of different types of aniso-metropia in myopic children.Methods A total of 99 myopic children aged 8 to 16 years who got the orthokeratology len-ses at the Department of Ophthalmology,Heping Hospital Affiliated to Changzhi Medical College from September 2020 to November 2022 with complete data were included.These children were divided into the simple myopic anisometropia group(monocular myopia,binocular diopter difference ≥ 1.00 D,n=39)and the compound myopic anisometropia group(binoc-ular myopia,binocular diopter difference ≥ 1.00 D,n=60).The children with higher anisometropia(binocular diopter difference ≥ 2.50 D)in the two groups were set as the high anisometropia subgroup(n=18 and 29,respectively),and chil-dren with lower anisometropia(1.00 D≤ binocular diopter difference＜2.50 D)were set as the low anisometropia subgroup(n=21 and 31,respectively).In each group,eyes with a higher diopter were set as the high diopter eyes,and the contra-lateral eyes with a lower diopter were set as the low diopter eyes.Diopter,corneal topography,intraocular pressure,cor-neal endothelium and axial length of children in the two groups were examined and recorded.The changes in axial length before and after wearing orthokeratology lenses for 1 year were compared between the two groups,analyzing the correla-tion between the degree of anisometropia and changes in the binocular axial length.Results After wearing orthokeratolo-gy lenses for 1 year,children in both groups had an increase in the axial length with a lower increase in the axial length of the high diopter eyes compared to the low diopter eyes;before and 1 year after wearing orthokeratology lenses,the axial length of high diopter eyes was greater than that of the low diopter eyes in both groups,and the differences were statistical-ly significant(all P＜0.05).Both groups of children showed a decrease in the binocular axial length difference after wear-ing the orthokeratology lenses for 1 year;before and 1 year after wearing orthokeratology lenses,the binocular axial length difference of children in the simple myopic anisometropia group was greater than that in the compound myopic anisometro-pia group,and the differences were statistically significant(t=4.903 and 2.670;both P＜0.05).The changes in binocular axial length difference before and after wearing the orthokeratology lenses of children in the high anisometropia subgroup and low anisometropia subgroup of the simple myopic anisometropia group were greater than those in the high anisometro-pia subgroup and low anisometropia subgroup of the compound myopic anisometropia group,respectively,and the differ-ences were statistically significant(both P＜0.05).In the simple myopic anisometropia and compound myopic anisometro-pia groups,the degree of anisometropia was positively correlated with the binocular axial length changes before and 1 year after wearing the orthokeratology lenses(r=0.423 and 0.510,both P＜0.05).Conclusion Orthokeratology lenses can effectively reduce the difference in binocular axial length of children with myopic anisometropia,and their control effect on simple myopic anisometropia is better than that of compound myopic anisometropia.

Neurodegenerative diseases are often associated with inflammatory mechanisms, where persistent or excessive inflammatory responses can lead to neuronal damage and subsequent pathological changes. In acute neurological conditions such as stroke or traumatic brain injury, inflammation is a key factor that triggers acute neuronal injury and long-term sequelae. In chronic neurodegenerative diseases, including Alzheimer's disease, cognitive dysfunction, Parkinson's disease, and multiple sclerosis, the chronic activation of inflammation is closely related to gradual degeneration of neurons. Resolvin D1 (RvD1), an endogenous pro-resolving mediator, plays a crucial role in controlling the intensity and duration of inflammation by inhibiting excessive activation of immune cells, modulating the release of pro-inflammatory cytokines, and maintaining the integrity of the blood-brain barrier. This review focuses on the mechanisms of RvD1 in mediating inflammatory damage in major neurological diseases, aiming to provide theoretical support for a deeper understanding of disease mechanism, optimized therapeutic strategies, and enhanced outcome.

Objective To predict the target and molecular mechanism of Huayu Xiaopi decoction in the intervention of Precancerous lesions of gastric cancer(PLGC)based on network pharmacology and molecular docking technology,and to conduct experimental verification.Methods A total of 60 SPF SD male rats were randomly selected as blank control,and the other rats were replicated in PLGC model.After successful modeling,the rats were randomly divided into model group,folic acid group(2 mg·kg-1·d-1),Huayu Xiaopi decoction high,medium and low dose groups(24.8,12.4,6.2 g·kg-1·d-1),which were continuously administered for 90 days.The body mass and food intake of rats at 3 h were recorded,and the gastric histopathology was observed by HE staining.Network pharmacology and molecular docking techniques were used to predict the potential targets of Huayu Xiaopi decoction in PLGC intervention,and the core targets were verified by Western blot technique.Results Compared with the blank group,the body mass and 3 h food intake of rats in the model group were significantly decreased(P<0.05),the gastric mucosa of rats was significantly thinner,the glands were significantly reduced and disordered,and the intestinal metaplasia goblet cells and a large number of inflammatory cells were visible in some areas.Compared with the model group,the body mass and 3 h food intake of rats in each administration group were improved to varying degrees.Huayu Xiaopi Decoction improved significantly in medium and high doses(P<0.05),the gastric mucosa was repaired in different degrees,the glandular arrangement tended to be orderly,and the inflammatory cells in the interstitial were gradually reduced.The results of network pharmacology and molecular docking showed that TP53,JUN and MAPK3/1(ERK1/2)were the core targets of Huayu Xiaopi decoction in the intervention of PLGC.Molecular biological detection results showed that compared with blank group,the protein phosphorylation levels of TP53,c-Jun and ERK1/2 in gastric tissue of model group were significantly increased(P<0.05).Compared with model group,the protein phosphorylation levels of TP53,c-Jun and ERK1/2 in gastric tissue of rats in all administration groups were decreased to different degrees,and significantly decreased in Huayu Xiaopi decoction high-dose and medium-dose groups(P<0.05).Conclusion Huayu Xiaopi Decoction can significantly improve the survival condition of PLGC rats and promote gastric mucosal repair,the specific mechanism of which may be related to the decrease of ERK1/2,c-Jun and TP53 protein phosphorylation levels in gastric tissue of PLGC rats,and then regulate the downstream signaling molecular response.
