AIM: To investigate the abnormal conditions and change patterns of accommodative facility in patients with different refractive states before and after small incision lenticule extraction(SMILE)surgery.METHODS:A prospective clinical cohort study was conducted. A total of 59 patients(118 eyes)who underwent SMILE surgery and had visual function files established in our hospital from June to December 2023 were randomly selected, including 37 males and 22 females, aged 18-35 years(with an average age of 25.19±5.65 years). According to the preoperative spherical equivalent(SE), they were divided into two groups: the low-to-moderate myopia group(SE≥-6.00 DS)with 40 patients(80 eyes), and the high myopia group(SE<-6.00 DS)with 19 patients(38 eyes). The monocular and binocular accommodative facility before surgery and at 1 wk and 1 mo after surgery were compared, and the changes in accommodative facility before and after SMILE surgery in the two groups of patients were analyzed.RESULTS:All surgeries were completed successfully. In the low-to-moderate myopia group, 33 cases(66 eyes)completed the 1-month follow-up after surgery, with a loss to follow-up rate of 17.5%(7/40). In the high myopia group, 15 patients(30 eyes)completed the 1-month follow-up after surgery, with a loss to follow-up rate of 21.1%(4/19). After SMILE surgery, the uncorrected visual acuity and SE of both low-to-moderate myopia and high myopia were significantly improved(all P<0.05). The accommodative facility of the right eyes in all the patients at 1 mo after surgery was better than that before surgery and at 1 wk after surgery(P=0.002, 0.006), the accommodative facility of the left eyes was significantly increased at 1 mo after surgery than that at 1 wk after surgery(P=0.005), and the binocular accommodative facility at 1 mo after surgery was significantly increased compared with that before surgery(P<0.017). Furthermore, there were statistical significance in accommodative facility of the right eyes in the low-to-moderate group at 1 mo compared with that before surgery and at 1 wk after surgery(P=0.011, 0.004); it was significantly increased in the left eyes at 1 mo after surgery compared with that at 1 wk after surgery(P=0.001), and binocular accommodative facility at 1 mo after surgery was significantly better than that before surgery(P<0.001). Furthermore, there was no statistical significance in the right, left and binocular accommodative facility of patients in the high myopia group(all P>0.017).CONCLUSION: After SMILE surgery, the monocular accommodative facility shows a transient decrease and then exceeds the preoperative level at 1 mo after surgery, and the binocular accommodative facility gradually improves after surgery. SMILE surgery has a positive impact on the monocular and binocular accommodative facility in patients with low-to-moderate myopia, but has no significant impact on the accommodative facility in patients with high myopia. It is of clinical significance to strengthen the detection of monocular and binocular accommodative facility before and after SMILE surgery.

They were grouped according to the degree of myopia, including 24 cases(48 eyes)in the low myopia group(-3.00 D

ObjectiveBased on network pharmacology and transcriptomics， the mechanism of Zishen Qinggan prescription （ZSQGF） in improving glucose and lipid metabolism in type 2 diabetes （T2DM） model rats was explored. MethodBased on network pharmacology analysis of the differential genes between ZSQGF and T2DM， gene ontology（GO）analysis and Kyoto encyclopedia of genes and genomes（KEGG） analysis were conducted， and molecular docking analysis was used to verify the binding between components and targets. A T2DM rat model was established by high-fat feeding and injection of streptozotocin （STZ）. The rats were randomly divided into the control group， model group， metformin （Met， 72 mg·kg^-1） group， and ZSQGF high-， medium-， and low-dose groups （ZSQGF-H， ZSQGF-M， and ZSQGF-L， with 4.8， 2.4， and 1.2 g·kg^-1 raw drug in the solution）. The living status of rats was monitored and the levels of total cholesterol （TC）， total triglycerides （TG）， high density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， aspartate aminotransferase （AST）， and alanine aminotransferase （ALT） in rat serum were detected. The liver tissues were subjected to Hematoxylin eosin（HE） staining and oil red O staining. The differential genes were analyzed through transcriptomics， GO and KEGG analysis， and the protein-protein interaction（PPI） network was obtained to screen key targets. With network pharmacology and transcriptomics analysis results， the protein pathways were identified. The expression levels of nuclear factor-κB （NF-κB）， matrix metalloproteinase（MMP）-1 and MMP-9 proteins in liver tissues were detected by Western blot. The mRNA expression of B-cell lymphoma-2（Bcl-2） modifying factor（BMF）， nicotinamide adenine dinucleotide phosphate （NADPH） oxidase 4 （NOX4）， and fatty acid synthase（FASN） was detected by real-time polymerase chain reaction（Real-time PCR）. The expression of MMP-1 and MMP-9 in the liver was detected by immunofluorescence staining. ResultTranscriptomics and network pharmacology analysis suggested that ZSQGF may protect the liver through the glucose and lipid metabolism pathway and the inflammation pathway. Experiments showed that after 8 weeks of administration， the body weight， blood sugar， serum indicators， and pathological staining results of rats were improved. Western blot results indicated a decrease in the relative expression levels of NF-κB， MMP-1 and MMP-9 proteins in the liver. Real-time PCR results showed a decrease in the transcriptional expression of BMF， NOX4， and FASN in the ZSQGF-H group， while immunofluorescence staining results present decreased expression of MMP-1 and MMP-9 in the ZSQGF groups. ConclusionZSQGF can improve the glucose and lipid metabolism by inhibiting the expression of FASN， reducing lipid synthesis， and regulating the NF-κB signaling pathway.

The nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)inflammasome is an inflammatory protein complex, and can participate into the inflammatory response. Upon activation, these inflammasomes can lead to Caspase-1 activation, thereby inducing a cascade of inflammatory factor activation and further cell pyroptosis. Excessive activation of inflammasomes will induce the overexpression of inflammatory factors, persistently triggering immune dysregulation and inflammatory chain reactions, even causing severe damage. The recent studies have confirmed a close association between retinal diseases, such as diabetic retinopathy(DR), retinal ischemia-reperfusion injury(RIRI), and proliferative vitreoretinopathy(PVR)with immune dysregulation and inflammatory responses, which is serving as crucial factors in the progression of retinal diseases. This article reviews the NLRP3 inflammasome signaling pathway and its role in the occurrence and development of retinal diseases, in order to provide new ideas for the pathogenesis and prevention of retinal diseases.

Apoptosis inhibitor of macrophage(AIM)belongs to group B of the scavenger receptor cysteine rich-super family.AIM is a soluble protein secreted by macrophages.The expression of this protein is controlled by the liver X receptor.AIM,which is secreted by macrophages,plays important and broad roles in the immune responses of the body.It not only inhibits the apoptosis of macrophages but also participates in the regulation of macrophage polarization.In addition,studies have revealed that AIM is involved in various physiological and pathological processes,such as inflammation,obesity,atherosclerosis,and cancer.It has been used as a biological marker for the diagnosis of diseases such as tuberculosis and liver cirrhosis.Moreover,it can promote the lipolysis of adipose cells by inhibiting the activity of fatty acid synthase(FAS),playing an important role in the regulation of lipid homeostasis,lipid metabolism,and autoimmune diseases.In this paper,we review the multiple functional characteristics of AIM and its effects on inflammation,lipid metabolism,and related diseases to provide a theoretical basis for relevant medical research.

Objective:To explore the regulatory effect of Suaeda salsa on renal apoprosis inhibitor of macrophage (AIM) and macrophage polarization in diabetes kidney disease (DKD) model rats.Methods:A DKD rat model was established using a high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin (STZ). The rats were divided into model group, metformin group, and Suaeda salsa high-, medium-, and low-dosage groups using a random number table method, with 8 mice in each group. The normal group was set with 8 rats in this group. The metformin group was given 85.71 mg/kg of metformin solution by gavage, while the Suaeda salsa high-, medium-, and low-dosage groups were given 3.08, 1.54, and 0.77 g/kg of Suaeda salsa suspension by gavage (raw dosage). The normal group and model group were given equal volumes of saline by gavage, once a day, administered by gavage for 12 weeks of intervention. Fasting blood glucose (FBG) and glucose tolerance (OGTT) were measured, and the area under the curve (AUC) was calculated; the levels of glycosylated hemoglobin (HbA1c) and glycosylated serum protein (GSP) were detected; urea nitrogen (BUN), serum creatinine (SCr), and 24-hour urine protein (24 hUP) were detected; HE staining was used to observe the pathological morphology of the kidneys; Masson and PAS staining were used to observe renal tissue fibrosis; Western blot method was used for detecting AIM, CD206, CD86, TNF-α and IL-10 protein levels in renal tissue; Immunofluorescence was used to detect the average optical density values of AIM, CD206, and CD86 proteins in renal tissue.Results:Compared with the model group, the FBG, OGTT AUC, HbA1c, GSP of each dosage group of Suaeda salsa decreased ( P<0.01); the expression levels of AIM, CD206, and IL-10 proteins in renal tissue increased ( P<0.01 or P<0.05), while the expression levels of CD86 and TNF-α protein significantly decreased ( P<0.01 or P<0.05); HE, Masson, and PAS staining results showed that compared with the model group, the changes in renal microvasculature and renal fibrosis of rats in each dosage group of Suaeda salsa were improved. Conclusion:Suaeda salsa may regulate AIM, promote polarization of M2 macrophages, improve the inflammatory microenvironment of macrophages, thereby lowering blood lipids of DKD rats, and improving renal pathological damage.

ObjectiveTo study the effects of Toddalia asiatica alcohol extract on autophagy and apoptosis of non-small cell lung cancer A549 cells， and to explore its possible mechanism. MethodA549 cells were cultured in vitro. Cell counting kit-8 （CCK-8） was used to detect the proliferation of A549 cells， and cell survival rate was calculated to screen the drug concentration. The apoptosis in each dose group and that after the use of 3-methyladenine （3-MA）， an autophagy inhibitor， were detected by flow cytometry combined with Annexin V-FITC/PI double staining. Western blot was used to detect the expression levels of apoptosis-related proteins such as B cell lymphocytoma-2（Bcl-2）， Bcl-2-associated X protein（Bax）， microtubule-associated protein 1 light chain 3 （LC3）， cleaved cysteinyl aspartate-specific protease-3 （cleaved Caspase-3）， activated poly （Adenosine diphosphate） ribonucleotide polymerase （cleaved PARP1）， PARP1， activated death activator （t-Bid）， Bid， and ubiquitin-binding protein p62 in each group and those after the use of 3-MA. ResultCompared with the conditions in the control group， the cell survival rate in 0.25 g·L^-1 group （P<0.05）， and 0.5， 1， 2， 4 g·L^-1 groups （P<0.01） was decreased after 24 h intervention. Additionally， the cell survival rate was reduced in a concentration-dependent manner at 48 h and it was less than 10% at 4 g·L^-1 （P<0.01）. Compared with the conditions in the control group， the total apoptosis rate in 0.5 g·L^-1 group was increased （P<0.05）， and the apoptosis rate in 1 and 2 g·L^-1 groups was also increased （P<0.01）. Compared with the 2 g·L^-1 group and 3-MA group， the 3-MA combined with T. asiatica alcohol extract had significantly decreased apoptosis rate （P<0.01）. Compared with the conditions in the control group， elevated expression of pro-apoptotic proteins cleaved PARP1， Bax and t-Bid in 1 and 2 g·L^-1 groups （P<0.05， P<0.01）， and reduced expression of Bid in the 2 g·L^-1 group （P<0.01） were found. Compared with the conditions in the control group， the expression of anti-apoptotic protein Bcl-2 （P<0.05， P<0.01） and the level of p62 （P<0.01） were down-regulated in 0.5， 1， 2 g·L^-1 groups， while the level of LC3 Ⅱ protein was up-regulated （P<0.01）， with certain concentration dependence. ConclusionT. asiatica alcohol extract could significantly inhibit the proliferation of A549 cells， which might be related to promoting autophagy and inducing apoptosis.

OBJECTIVE：To study the improvement effects of paeon iflorin（PF）on myocardial injury in type 2 diabetes mellitus（T2DM）model rats and its mechanism. METHODS ：The experiment was set up in the normal group ，model group ， positive control group （metformin 90 mg/kg），PF high-dose ，medium-dose and low-dose groups （90，60，30 mg/kg），with 8 rats in each group. Except for normal group ，other groups were given high-glucose and high-fat diet and intraperitoneal injection of streptozotocin （30 mg/kg） to induce T 2DM model. After modeling ， administration groups were given relevant medicine intragastrically，normal group and model group were given constant volume of normal saline intragastrically ，once a day ，for consecutive 4 weeks. The body weight ，fasting blood glucose and oral glucose tolerance were measured ；serum levels of glycosylated serum protein （GSP），total cholesterol （TC），triacylglycerol（TG），glutathione peroxidase （GSH-Px），superoxide dismutase（SOD），malondialdehyde（MDA），creatine kinase isoenzyme-MB （CK-MB） and troponin Ⅰ （cTn Ⅰ） were determined. The pathomorphological changes of myocardium were observed. The apoptosis index of rat cardiomyocytes was （ detected. The protein expression of B-cell lymphoma 2 （Bcl-2），Bcl-2 related X protein （Bax）and caspase- 3 in rat myocardium were detected by immunohistochemistry and Western blot. RE SULTS：Compared with normal group ，the body weight ，serum levels of GSH-Px and SOD ，protein expression of Bcl- 2 in myocardium were decreased significantly in model group（P＜0.01）；while fasting blood glucose ，area under blood glucose curve ，serum levels of biochemical indexes （GSP，TC， TG，MDA，CK-MB，cTnⅠ），cardiomyocyte apoptosis index ，protein expression of Bax and caspase- 3 in myocardium were increased significantly （P＜0.05 or P＜0.01）. The arrangement of myocardium was relatively irregular ，and some muscle fibers were broken. Compared with model group ，except for body weight ，serum levels of SOD and MDA ，the protein expression of Bax in myocardium in PF low-dose group ， above indexes of PF groups were reversed significantly （P＜0.05 or P＜0.01）. CONCLUSIONS：PF can regulate glycolipid metabolism ，enhance antioxidant ability ，inhibit cardiomyocyte apoptosis and improve myocardial injury in T 2DM model rats ；the mechanism may be associated with increasing the protein expression of Bcl- 2 and down-regulating the protein expression of Bax and caspase- 3 in myocardium.
