ObjectiveTo explore the mechanism by which Banxia Xiexin Tang （BXT） regulates the advanced glycation end products （AGE）/receptor for advanced glycation end products （RAGE） signaling pathway to reduce neuroinflammatory responses and ameliorate cognitive dysfunction in the rat model of vascular dementia （VD）. MethodsThe components of BXT were detected by ultra performance liquid chromatography-quadrupole -orbitrap-tandem mass spectrometry（UPLC-Q-Orbitrap-MS/MS）， and the core components and key action pathways were screened out by network pharmacology and molecular docking. Sixty SPF-grade male SD rats were randomly allocated into the sham and modeling groups by the random number table method. The VD model was replicated by the modified bilateral occlusion of the common carotid arteries （2-VO） method. The successfully modeled rats were randomly allocated into the model， low-， medium-， and high-dose （3.748 5， 7.497， 14.994 g·kg^-1） BXT （BXT-L， BXT-M， and BXT-H）， and nimodipine （NMP， 0.002 7 g·kg^-1） groups according to the random number table method. The rats in the drug intervention groups were administrated with corresponding drugs by gavage， and the sham and model groups received the same amount of normal saline for 14 consecutive days. The Morris water maze， Y-maze， and new object recognition experiments were conducted to evaluate the cognitive dysfunction of rats. Hematoxylin-eosin （HE） staining was used to evaluate the histopathological changes of the hippocampal tissue in rats. The mRNA levels of AGE， RAGE， and phosphorylated nuclear factor-kappa B p65 （p-NF-κB p65） in the hippocampal tissue of rats were determined by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The expression of related proteins in the AGE/RAGE pathway in the hippocampal tissue of rats was determined by Western blot and immunohistochemistry （IHC）. The levels of neurotransmitters and inflammatory mediators in the rat serum were measured by enzyme-linked immunosorbent assay （ELISA）. ResultsThe chemical components of BXT were detected by UPLC-Q-Orbitrap-MS/MS. Network pharmacology and molecular docking identified the AGE/RAGE pathway as the key pathway. The results of the water maze， Y maze， and novel object recognition tests showed that compared with the sham group， the model group demonstrated prolonged successful latency and decreases in number of platform crossings， alternation rate， number of entries into the new arm， preference index， and discrimination index （P0.01）. Compared with the model group， the BXT-H and BXT-M groups showed shortened successful latency （P0.01） and increases in number of platform crossings （P0.05）， alternation rate （P0.01）， number of entries into the new arm （P0.05）， preference index （P0.01）， and discrimination index （P0.01）. HE results showed that compared with the sham group， the cells of model rats were loosely and disorderly arranged， and the nuclei were condensed. Compared with the model group， the pathological changes of the hippocampus in the BXT group were mitigated. Real-time PCR results showed that compared with the sham group， the model group presented up-regulated mRNA levels of AGE， RAGE， and p-NF-κB p65 in the hippocampus （P0.01）， and compared with the model group， the BXT-H and BXT-M groups showcased down-regulated mRNA levels of AGE， RAGE， and p-NF-κB p65 （P0.01）. Western blot results showed that compared with the sham group， the model group presented up-regulated expression of AGE， RAGE， p-NF-κB p65， and tumor necrosis factor-α （TNF-α） （P0.05）， and compared with the model group， the BXT-H group presented down-regulated expression of AGE， RAGE， p-NF-κB p65， and TNF-α （P0.05）. IHC results showed that compared with the sham group， the model group had increased expression of RAGE （P0.01）， and compared with the model group， the BXT-H and BXT-M groups had reduced expression of RAGE （P0.01）. ELISA results showed that compared with the sham group， the model group exhibited elevated levels of TNF-α and Interleukin-1β （IL-1β） and declined levels of acetylcholine （ACh） and dopamine （DA） in the serum （P0.01）. Compared with the model group， the BXT-L， BXT-M， and BXT-H groups showed lowered levels of TNF-α and IL-1β in the serum （P0.05） and elevated levels of ACh and DA （P0.05）. ConclusionBXT may ameliorate cognitive dysfunction in the rat model of VD by down-regulating the AGE/RAGE signaling pathway， reducing neuroinflammatory responses， and regulating neurotransmitter levels.

Cancer has become a significant global public health issue， severely impacting public health and societal development. Despite advances in tumor treatment methods in recent years and a gradual decline in cancer mortality rates， drug-related adverse reactions and drug resistance remain substantial challenges. Traditional Chinese medicine （TCM） has demonstrated significant clinical efficacy in cancer treatment and small side effects， making it widely applied in the field of oncology. Xuefu Zhuyutang， derived from Yilin Gaicuo， is known for its abilities to invigorate blood circulation， dispel blood stasis， promote Qi flow， and alleviate pain. It was specifically formulated by the esteemed WANG Qingren of the Qing dynasty for the "blood stasis syndrome in the blood mansion" and is commonly used to treat Qi stagnation and blood stasis syndrome. Clinical studies have shown that Xuefu Zhuyutang， when combined with conventional Western medications， produces significant effects in the treatment of malignant tumors such as liver cancer， lung cancer， and cervical cancer. It substantially reduces the incidence of adverse reactions following Western treatments， including radiation esophagitis， radiation encephalopathy， radiation-induced oral mucositis， and edema. Additionally， it alleviates cancer-related pain and fever， blood hypercoagulability， and associated complications such as depression and anxiety， and also mitigates chemotherapy-induced side effects like hand-foot syndrome. Basic research has demonstrated its potential anti-tumor mechanisms， including the inhibition of Wnt/β-catenin signaling pathway activation， suppression of mitogen-activated protein kinase （MAPK） pathway activation， and anti-tumor angiogenesis. Pharmacological studies have revealed that its active components inhibit tumor cell proliferation and migration， induce tumor cell apoptosis， suppress tumor angiogenesis， enhance the cytotoxicity of natural killer cells against tumors， improve the tumor microenvironment， and regulate immune function. This paper reviewed the latest research progress on Xuefu Zhuyutang in the treatment of malignant tumors from four aspects： theoretical exploration， clinical studies， mechanisms of action， and pharmacological basis， aiming to provide insights and methods for the clinical diagnosis and treatment of malignant tumors.

ObjectiveTo observe the effects of Jiangtang No. 3 prescription on inflammatory pathways and insulin resistance-related indicators in rats with type 2 diabetes mellitus （T2DM）， and to elucidate its molecular mechanism in combating diabetes. MethodsA T2DM rat model was established using a high-fat diet combined with intraperitoneal injection of streptozotocin （STZ）. Successfully modeled rats were randomly assigned to the model group， metformin group， and low-， medium-， and high-dose Jiangtang No. 3 prescription groups， and a normal group was also set. Daily gavage was administered for 8 weeks as follows： metformin at 0.1 g·kg^-1·d^-1， Jiangtang No. 3 prescription granules at 1.62， 3.24， 6.48 g·kg^-1·d^-1 for the respective dose groups， and sterile water for the normal and model groups. Rat body weight， fasting blood glucose （FBG）， oral glucose tolerance test （OGTT）， and insulin tolerance test （ITT） were measured. After drug intervention， enzyme-linked immunosorbent assay （ELISA） was used to determine serum levels of total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL）， high-density lipoprotein cholesterol （HDL）， non-esterified fatty acids （NEFA）， interleukin （IL）-1β， IL-18， and insulin （INS）. Hematoxylin-eosin （HE） staining was used to observe morphological changes in adipose tissue. Real-time quantitative PCR was used to detect the mRNA expression of Toll-like receptor 4 （TLR4）， nuclear factor-κB （NF-κB）， NOD-like receptor protein 3 （NLRP3）， Caspase-1， IL-1β， IL-18， and gasdermin D （GSDMD） in adipose tissue. Western blot was used to measure the corresponding protein expression levels. ResultsCompared with the model group， Jiangtang No. 3 prescription groups exhibited significantly increased body weight （P<0.05， P<0.01）， significantly reduced FBG （P<0.05， P<0.01）， significant reductions in TC， TG， NEFA， and LDL （P<0.05， P<0.01）， and a significant increase in HDL （P<0.01）. Serum levels of inflammatory mediators IL-1β and IL-18 were significantly decreased （P<0.01）， the homeostatic model assessment of insulin resistance （HOMA-IR） index was significantly reduced （P<0.05， P<0.01）， and adipose tissue pathology was improved. The protein expression levels of TLR4， NF-κB， NLRP3， Caspase-1， IL-1β， IL-18， and GSDMD were markedly decreased （P<0.05， P<0.01）， and the mRNA expression levels of these indicators were also significantly downregulated （P<0.05， P<0.01）. Some effects were superior to those of the positive control drug metformin， and certain indicators exhibited dose-dependent improvements. ConclusionT2DM rats display significant inflammatory responses， disordered glucose and lipid metabolism， and insulin resistance. Jiangtang No. 3 prescription effectively suppresses inflammatory mediators， improves glucose and lipid metabolism and insulin resistance， and ameliorates pathological changes in adipose tissue. Its mechanism may be related to the regulation of the TLR4/NF-κB/NLRP3 signaling pathway in visceral adipose tissue， thereby influencing downstream inflammatory mediators.

Background Pyrethroid pesticides (PYRs) can cross the placental barrier to cause intrauterine fetal exposure, which may lead to developmental immunotoxicity (DIT). However, the specific effect of maternal PYR exposure during pregnancy on the cellular immune function of 1-year-old children remains unclear. Objective To explore the effect of PYRs exposure throughout the entire pregnancy on peripheral blood lymphocytes in 1-year-old children and potential sensitive window period of PYRs exposure. Methods A birth cohort was established by enrolling pregnant women in their first trimester and following them and their infants until one year of age. Ultra-high performance liquid chromatography-tandem mass spectrometry was used to detect the levels of PYRs metabolites, including 3-phenoxybenzoic acid (3PBA), 4-fluoro-3-phenoxybenzoic acid (4F3PBA), and cis-3-(2,2-dichlorovinyl)-2,2- dimethylcyclopropane carboxylic acid (cis-DBCA), in the urine of pregnant women during the first trimester (gestational weeks 6-12), the second trimester (gestational weeks 21-24), and the third trimester (gestational weeks 33-36). Peripheral blood leukocyte and lymphocyte counts were measured in children at 12 months of age using the Coulter principle combined with flow cytometry. Exposure levels of PYRs metabolites in each trimester were divided into low, moderate, and high exposure groups based on the 25th (P₂₅) and 75th (P₇₅) percentiles. Meanwhile, participants were classified as having repeated high or low exposure if their metabolite levels were > P₇₅ or <P₂₅ in at least two trimesters, respectively, while all others were categorized as having repeated moderate exposure. Generalized linear models were used to analyze the associations between trimester-specific and repeated PYRs metabolite exposure levels and the peripheral blood white blood cell (WBC) and lymphocyte counts in children aged 1 year. Results A total of 336 mother-child pairs were included in this study. For the pregnant women, the total detection rates of maternal urinary 3PBA, 4F3PBA, and cis-DBCA across the three trimesters of pregnancy were 80.5%, 100.0%, and 81.3%, respectively; and median creatinine-corrected concentrations were 0.24, 0.36, and 0.42 μg·g⁻¹, respectively. In children aged 1 year, the mean WBC and lymphocyte counts in peripheral blood were (8.9±2.0)×10⁹·L⁻¹ and (5.7±1.6)×10⁹·L⁻¹, respectively. The results of the generalized linear model analysis indicated that compared to the low exposure group, the high cis-DBCA exposure group during the third trimester of pregnancy had significantly lower peripheral blood WBC count (β=−0.87, 95%CI: −1.51, −0.23) and lymphocyte count (β=−0.64, 95%CI: −1.15, −0.13); and the repeated high-exposure group of cis-DBCA had significantly lower peripheral blood WBC count (β=−1.34, 95%CI: −2.34, −0.34) and lymphocyte count (β=−0.80, 95%CI: −1.60, −0.01) than the repeated low exposure group. Similarly, the repeated moderate-exposure group of cis-DBCA had a significantly lower peripheral blood WBC count (β=−0.83, 95%CI: −1.59, −0.07) than the repeated low exposure group. Conclusion High maternal exposure to PYRs with cis-DBCA as the major metabolite exposure is associated with decreased peripheral leukocyte and lymphocyte counts in children aged 1 year, and repeated high-level exposure throughout gestation appears to exacerbate DIT in offspring. The third trimester of pregnancy maybe a sensitive window for children's DIT induced by exposure to PYRs during pregnancy.

OBJECTIVE To explore the antidepressant mechanism of Wenyang jieyu granules （WYJYG） via the NOD-like receptor thermal protein domain associated protein 3 （NLRP3）/apoptosis-associated speck-like protein containing a CARD （ASC）/Caspase-1 pathway. METHODS A rat model of depression was established by chronic unpredictable mild stress combined with single-housing for 42 consecutive days.The experiment set up blank group， model group， MCC950 （NLRP3 inflammasome inhibitor） group （10 mg/kg）， fluoxetine group （positive control，2.08 mg/kg），low-dose WYJYG（3.78 g/kg） and high-dose WYJYG group （7.56 g/kg），with 10 rats in each group. From the 22nd day of the experiment， rats in the fluoxetine group， low-dose and high-dose WYJYG groups were intragastrically administered with the corresponding drugs and intraperitoneally injected with an equal volume of normal saline. Rats in the MCC950 group were intraperitoneally injected with MCC950 at the corresponding concentration and intragastrically administered with an equal volume of distilled water. Rats in the blank group and model group were given an equal volume of distilled water by gavage and an equal volume of normal saline by intraperitoneal injection. All interventions were performed once a day for 21 consecutive days. Behavioral tests were conducted once a week. After the last administration， the contents of ASC， ionized calcium binding adaptor molecule 1 （Iba1）， interleukin-1β （IL-1β）， and IL-18 in hippocampal tissues were detected. The protein expressions of NLRP3， cluster of differentiation 68 （CD68）， Caspase-1， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein were determined， and neuronal apoptosis was observed. RESULTS After the last administration， compared with the model group， the open-field activity time was significantly prolonged （ P ＜0.05）， and the latency to feed in a novel environment was significantly shortened （ P ＜0.05） in rats of the high-dose WYJYG group. In hippocampal tissue， the contents of ASC， Iba1， IL-1β， and IL-18， as well as the protein expression levels of NLRP3， Caspase-1， and CD68， and the positive rate of neuronal apoptosis were all significantly decreased/downregulated （ P ＜0.05）. Bcl-2 protein expression was significantly upregulated （ P ＜0.05）， and the density of neuronal apoptosis-positive cells was significantly reduced （ P ＜0.05）. CONCLUSIONS WYJYG play on antidepressant role by inhibiting the NLRP3/ASC/Caspase-1 pathway， reducing microglia-mediated neuroinflammation， and inhibiting hippocampal neurons apoptosis.

AIM: To investigate the alterations in corneal aberration and relative refractive power following the reduction of back optic zone diameters(BOZD)of orthokeratology lenses.METHODS: Myopic children aged 8-12 years, deemed suitable and willing to wear orthokeratology lenses, were randomly allocated to wear lenses with a 6.0 mm BOZD or a 5.0 mm BOZD. Data collection included changes in higher-order aberrations, relative refractive power and the treatment zone diameter of the two groups after wearing lenses for 1 d, 1 wk, 1, and 3 mo. The correlation of increase in corneal higher-order aberrations with refractive power was analyzed.RESULTS: The increases in total higher-order aberrations, spherical aberrations and coma aberrations varied over time following lens wear(all P<0.001), and there were no statistically significant differences in the changes of total higher-order aberrations and coma aberrations between the two groups of patients(all P>0.05). A significant difference was observed in the increment of spherical aberrations in the 5 mm range between the two groups of patients, which varied over time(Ftime=40.179, Ptime<0.001; Fgroup=11.948, Pgroup=0.001; Finteraction=3.262, Pinteraction=0.03). A significant difference was observed in the increment of spherical aberrations in the 4 mm range between the two patient groups(Ftime=34.462, Ptime<0.001; Fgroup=13.094, Pgroup<0.001; Finteraction=1.372, Pinteraction=0.25). There was no statistically significant distinction in relative refractive power between the two groups(Fgroup=0.048, Pgroup=0.83; Finteraction=1.208, Pinteraction=0.31); however, relative refractive power changed over time(Ftime=40.030, Ptime<0.001). The difference in treatment zone diameter between the two groups was statistically significant, with changes over time(Ftime=11.212, Ptime<0.001; Fgroup=74.073, Pgroup<0.001; Finteraction=0.312, Pinteraction=0.82). The total higher-order aberrations, spherical aberrations, and coma aberrations in 4, 5 and 6 mm range showed a positive correlation with relative refractive power values(all P<0.001). Statistically significant difference was observed in the axial length between the two groups after wearing lenses for 3, 6 and 12 mo(Ftime=185.398, Ptime<0.001; Fgroup=5.618, Pgroup=0.02; Finteraction=2.315, Pinteraction=0.11).CONCLUSION: Orthokeratology lenses leaded to elevated higher-order aberrations. Orthokeratology lenses with smaller BOZD produced significantly greater spherical aberrations at 4 and 5 mm range and smaller treatment zone diameters. The corneal total higher-order aberration was positively correlated with relative refractive power. Wearing orthokeratology lenses with a smaller BOZD can cause slower axial growth and better myopia control.

Objective : To construct a human keratinocyte-forming cell line(HaCaT) with stable knockout of the G protein-coupled receptor 107(GPR107) gene, and to preliminarily investigate the effect of GPR107 deletion on the biological behaviour of HaCaT cells. Methods : Using CRISPR/Cas9 gene editing technology, HaCaT cells with knockout ofGPR107gene were constructed and monoclonal cells with GPR107 deletion were obtained by limited dilution method.
