OBJECTIVE To provide a scientific basis for the quality evaluation and clinical application of Qingwen hufei granules. METHODS Fourteen batches of Qingwen hufei granules were used as samples to establish high-performance liquid chromatography (HPLC) fingerprints using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (2012 Edition). The chromatographic peaks were identified and the similarity was evaluated. Cluster analysis (CA), principal component analysis (PCA), and orthogonal partial least squares-discriminant analysis (OPLS-DA) were used to conduct chemical pattern recognition analysis on the 14 batches of samples. Meanwhile, the contents of neochlorogenic acid (NGA), chlorogenic acid (CHA), cryptochlorogenic acid (CGA), forsythoside A (FTA), 3,5-O-dicaffeoylquinic acid (3,5-O- DA), 4,5-O-dicaffeoylquinic acid (4,5-O-DA), and angoroside C (AGC) in the samples were determined by HPLC. RESULTS The methodological investigation results of both the fingerprint and the content determination complied with the relevant requirements. Fourteen common peaks were indicated in the HPLC fingerprints of the 14 batches of samples, and 7 of them were identified [NGA (peak 2), CHA (peak 3), CGA (peak 5), FTA (peak 11), 3,5-O-DA (peak 12), 4,5-O-DA (peak 13), and AGC (peak 14)]; the similarity of each sample was greater than 0.94. The results of CA and PCA showed that the samples could be classified into 3 categories; the results of OPLS-DA indicated that peak 4 (unknown), peak 11 (FTA), peak 8 (unknown), peak 9 (unknown), and peak 1 (unknown) were the differential components. The content ranges of NGA, CHA, CGA, 3,5-O-DA, FTA, 4,5-O-DA and AGC in the 14 batches of samples were 0.210 4-0.458 7, 0.269 1-0.506 3, 0.228 1-0.461 1, 0.443 9-1.044 6, 0.066 7-0.155 7, 0.062 8-0.143 8, and 0.057 4-0.105 7 mg/g, respectively. CONCLUSIONS The HPLC fingerprint and multi-component content determination methods established in this study are efficient and reliable, and can be used for the quality evaluation of Qingwen hufei granules.

OBJECTIVE To predict and validate the mechanisms of Chaiqi yigan granules (CQYG) improving hepatocellular carcinoma (HCC). METHODS The signaling pathways of CQYG intervention in HCC were predicted using network pharmacology. A mice model of transplanted hepatocellular carcinoma was established by injecting H22 hepatoma cells into the axilla. Successfully modeled mice were randomly divided into model group (normal saline), sorafenib group (positive control, 50 mg/kg), and CQYG low-, medium- and high-dose groups (24.83, 49.66, 99.32 g/kg), with 10 mice in each group. Mice in each group were administered the corresponding drug solution or normal saline intragastrically, once a day, for 14 consecutive days. After last administration, pathological morphological changes in the tumor tissues of mice were observed in each group. Immunohistochemical staining was performed to detect the expression of the nuclear proliferation antigen Ki-67 in tumor tissues of mice. Western blot assay was used to measure the expression of proteins related to epithelial-mesenchymal transition (EMT) [N-cadherin, E-cadherin, Vimentin, matrix metalloproteinase 7 (MMP7)] and the mitogen-activated protein kinase (MAPK) signaling pathway [p38 MAPK, phosphorylated p38 MAPK, c-Jun N-terminal kinase (JNK), phosphorylated JNK, extracellular regulated protein kinase 1/2 (ERK1/2), phosphorylated ERK1/2] in tumor tissue of mice. RESULTS Network pharmacology analysis revealed that metabolic pathways, pathways in cancer, and the MAPK signaling pathway were key signaling pathways through which CQYG exert their anti-hepatocellular carcinoma effects. In animal experiments, the tumor tissues of mice in the model group exhibited dense tumor cells and vigorous growth. Compared with model group, CQYG high-dose group showed a decreased density of tumor cells in the tumor tissues of mice. Moreover, the expression levels of Ki-67, N-cadherin, MMP7 and Vimentin proteins, along with the phosphorylation levels of ERK1/2 and JNK proteins, were all significantly reduced ( P <0.05). The expression level of E-cadherin protein was significantly increased ( P <0.05), the phosphorylation level of p38 MAPK protein was increased, the difference was not statistically significant ( P >0.05). CONCLUSIONS CQYG can inhibit EMT by regulating the MAPK signaling pathway, thereby suppressing tumor cell invasion and metastasis and ultimately exerting a therapeutic effect in improving HCC.

Background Prolonged vibration exposure can lead to vascular endothelial cell dysfunction and cellular injury. However, research on the association between vibration and ferroptosis in vascular endothelial cells remains insufficient. Objective To explore whether occupational vibration exposure is associated with alterations in serum markers related to ferroptosis in patients with hand-arm vibration disease (HAVD), and to further investigate, through in vitro cell experiments, whether vibration exposure may induce ferroptosis in vascular endothelial cells. Methods ①A judgmental sampling method was employed to select 50 workers with HAVD (the HAVD group), 50 vibration-exposed workers without HAVD (the vibration exposure group), and 50 non–hand-transmitted vibration-exposed workers (the control group). Serum iron levels, malondialdehyde (MDA) content, and superoxide dismutase (SOD) levels were measured using serum iron assay kits, MDA detection kits, and SOD detection kits, respectively. One-way analysis of variance and binary logistic regression analysis were performed to examine the relationships between these indicators and HAVD. ②Human umbilical vein endothelial cells (HUVEC) were divided into a vibration group and a control group. The vibration group was subjected to vibration at 120 Hz with an acceleration of 6.5 m·s−2 and further subdivided into four subgroups: 1 d 2 h, 1 d 4 h, 2 d 2 h, and 2 d 4 h. The control group was treated identically except for vibration exposure. Cellular iron (Fe2+) content and reduced glutathione (GSH) levels in HUVEC were measured using ferrous iron colorimetric assay kits and GSH colorimetric assay kits, respectively, to assess the effects of different vibration exposure schedules. Real-time quantitative polymerase chain reaction (RT-qPCR) was performed to detect the mRNA expression levels of ferroptosis-related genes, including acyl-CoA synthetase long-chain family member 4 (ACSL4), tumor suppressor protein P53 (P53), ferritin heavy chain 1 (FTH1), and glutathione peroxidase 4 (GPX4). Western blot analysis was conducted to determine the protein expression levels of ferroptosis-related markers in HUVEC. Results ①Compared with the control group, the patients in the HAVD group showed increased serum iron and MDA levels, along with decreased SOD levels (P<0.05). The logistic regression analysis indicated that elevated serum iron levels were significantly associated with an increased risk of HAVD (OR=4.034; 95%CI: 2.063, 7.887), and elevated MDA levels were also associated with an increased risk of HAVD (OR=1.523; 95%CI: 1.026, 1.936). ②Compared with the control group, increased intracellular Fe2+ content and decreased GSH content were observed in HUVECs in the 1 d 4 h and 2 d 4 h vibration subgroups (P<0.05). The RT-qPCR results showed that, compared with the control group, vibration exposures of 1 d 4 h and 2 d 4 h significantly upregulated the expression of ACSL4 and P53 (P<0.05), whereas the mRNA expression levels of GPX4 and FTH1 were downregulated in all vibration-exposed endothelial cells (P<0.05). The Western blot results revealed that, compared with the control group, the vibration exposure schedules of 1 d 2 h and 1 d 4 h significantly upregulated the protein expression levels of ACSL4 and P53 (P<0.05), while the vibration exposure schedules of 1 d 4 h, 2 d 2 h, and 2 d 4 h significantly downregulated the protein expression levels of FTH1 and GPX4 (P<0.05). Conclusion Occupational vibration exposure is associated with alterations in iron metabolism and oxidative stress status in workers with HAVD. The in vitro experiments further demonstrates that vibration stimulation induces intracellular iron accumulation and reduces antioxidant capacity in vascular endothelial cells, accompanied by dysregulated expression of ferroptosis-related molecules. These findings suggest that ferroptosis may play a role in vibration-induced vascular injury and the pathogenesis of HAVD.
5.Advances in basic and clinical research on primary pigment dispersion syndrome
International Eye Science 2026;26(5):805-810
Primary pigment dispersion syndrome(PDS)is characterized by pigment granules released from the pigment epithelium of iris, and their deposition in anterior segment of eye, particularly in the trabecular meshwork(TM). This condition may lead to elevated intraocular pressure(IOP),which further causes optic nerve damage, and progresses to pigmentary glaucoma(PG). PDS predominantly affects young myopic individuals and shows heterogeneous clinical manifestations. It may occur sporadically or in familial inheritance. It has been reported that the pathogenic genes include those involved in melanogenesis and melanosome homeostasis(e.g., PMEL, MC1R, SLC45A2, and TYR), and genes related to ocular development and anterior segment formation(e.g., CPAMD8, GSAP, and GRM5).The pathogenesis of PDS is closely associated with posterior iris concavity and reverse pupillary block, which may change the dynamics of aqueous humor, along with persistent liberation of pigmented granules by friction of iris and zonules. Pigmented granules accumulating in the TM may cause mechanical obstruction of TM, and increase the phagocytic burden of the cells, and result in cellular dysfunction and structural damage of TM. All these changes contribute to sustained elevation of IOP and optic neuropathy. Primary management of PDS involves regular follow-up and assessment of the risk of IOP elevation. Laser peripheral iridotomy may be considered to reduce posterior iris concavity in PDS. Treatment of PG focuses on IOP control for long term, which include topical medications, laser trabeculoplasty, and filtering or drainage surgery. Development of experimental animal models harboring human pathogenic genes and exhibiting PDS phenotypes is needed to facilitate in-depth research into the pathogenesis of PDS.

ObjectiveTo explore the protective effect and underlying mechanism of Gegen Qinliantang on cognitive function in db/db mice with diabetic cognitive impairment (DCI). MethodsThirty-two 8-week-old male db/db mice were randomly assigned to the model group, dapagliflozin group (1.0 mg·kg-1·d-1), low-dose Gegen Qinliantang group (6.24 g·kg-1·d-1), and high-dose Gegen Qinliantang group (24.96 g·kg-1·d-1). Eight db/m mice served as the normal group. All mice were administered the corresponding treatment once daily by gavage for 10 consecutive weeks. Body weight and fasting blood glucose (FBG) were dynamically monitored. The Morris water maze test was used to evaluate cognitive function. Hematoxylin-eosin (HE) staining and Nissl staining were used to observe pathological changes in the hippocampus. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in hippocampal tissue. Immunofluorescence double staining was used to detect the co-expression of M1 microglial marker CD16/32 and ionized calcium-binding adapter molecule 1 (IBA1) in the hippocampus. Western blot analysis was performed to detect the protein expression of postsynaptic density protein 95 (PSD-95), synapsin (SYN), nuclear factor-κB p65 (NF-κB p65), and phosphorylated NF-κB p65 (p-NF-κB p65) in the hippocampus. ResultsCompared with the normal group, the model group showed significantly increased body weight and FBG levels (P<0.01), significantly prolonged escape latency and reduced platform crossings in the Morris water maze test (P<0.01), disordered arrangement of hippocampal neurons, nuclear pyknosis, increased neuronal necrosis, reduced Nissl bodies, decreased expression of synaptic proteins PSD-95 and SYN (P<0.01), increased CD16/32+ /IBA1+ positive rate, elevated levels of TNF-α and IL-1β, and an increased p-NF-κB p65/NF-κB p65 ratio (P<0.01). Compared with the model group, the dapagliflozin group exhibited significantly reduced FBG levels at weeks 5 and 10 (P<0.05, P<0.01) and increased body weight. The high-dose Gegen Qinliantang group showed significantly reduced FBG at week 10 (P<0.05). Escape latency was significantly reduced on days 3 and 5 of the water maze test in the dapagliflozin group and on day 5 in the high-dose Gegen Qinliantang group (P<0.05). Platform crossings were significantly increased in both the dapagliflozin group and the high-dose Gegen Qinliantang group (P<0.05). Hippocampal pathological damage was alleviated to varying degrees in the dapagliflozin group and the low- and high-dose Gegen Qinliantang groups, with significantly increased expression of PSD-95 and SYN (P<0.01). Further studies revealed that both low- and high-dose Gegen Qinliantang reduced hippocampal IL-1β levels and the CD16/32+/IBA1+ positive rate of microglia, while the high-dose group also significantly reduced hippocampal TNF-α levels and the p-NF-κB p65/NF-κB p65 (P<0.05, P<0.01). ConclusionGegen Qinliantang can improve hyperglycemia, cognitive dysfunction, and synaptic damage in DCI, inhibit M1 polarization of microglia and neuroinflammation, and its mechanism may be related to the inhibition of NF-κB activation.

Objective To compare the dosimetric differences in the heart and its substructures between two hybrid plans for hypofractionated whole-breast radiotherapy after breast-conserving surgery in patients with early-stage left-sided breast cancer. Methods A total of 46 patients with early-stage left-sided breast cancer who underwent hypofractionated whole-breast radiotherapy were randomly selected. Two hybrid radiotherapy plans were used, including hybrid intensity-modulated radiotherapy (H_IMRT) and hybrid volumetric-modulated arc therapy (H_VMAT). The heart and its substructures were contoured, including left anterior descending (LAD), left ventricle (LV), right coronary artery (RCA), and right ventricle (RV). The heart and substructure doses, as well as monitor units, were compared between H_IMRT and H_VMAT. Results Both hybrid plans met the clinical requirements. H_IMRT significantly outperformed H_VMAT for the heart (V10, V30, and Dmean), LAD (V30, V40, Dmax and Dmean), LV (V10, V20 and Dmean), RCA (Dmax, Dmean), and RV (V5, V10, Dmean) (P < 0.001). Additionally, H_IMRT was significantly superior to H_VMAT for heart V5, LAD V20, and RV V20 (P = 0.005, 0.035 and 0.037). For LAD (V15, V40) and LV (V5, V25), H_IMRT was slightly better than H_VMAT, and the difference was not statistically significant. Conclusion Both H_IMRT and H_VMAT hybrid radiotherapy plans are suitable for hypofractionated whole-breast radiotherapy after breast-conserving surgery in patients with early-stage left-sided breast cancer. H_IMRT is slightly better than H_VMAT in dose sparing for the heart and its substructures.

ObjectiveTo investigate the mechanisms by which the combination of berberine (BBR) and baicalin (BAI) ameliorates type 2 diabetes mellitus (T2DM) due to internal accumulation of dampness-heat from the perspectives of gut microbiota and metabolomics. MethodsAntibiotics were used to induce pseudo-sterile mice. Thirty pseudo-sterile mice were randomized into a normal fecal microbiota transplantation group (n=10) and a T2DM (syndrome of internal accumulation of dampness-heat) fecal microbiota transplantation group (n=20). The mice were then administrated with suspensions of fecal microbiota from healthy volunteers and a patient with T2DM due to internal accumulation of dampness-heat by gavage, respectively. Each mouse received 200 µL suspension every other day for a total of 15 times to reshape the gut microbiota. The T2DM model mice were then assigned into a model group (n=8) and a BBR-BAI group (n=11). BBR was administrated at a dose of 200 mg·kg-1, and BAI was administrated in a ratio of BBR-BAI 10∶1 based on preliminary research findings. The administration lasted for 8 consecutive weeks. Fasting blood glucose (FBG), glycated hemoglobin (HbA1c), insulin (INS), triglycerides (TG), total cholesterol (CHOL), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels were measured to evaluate the effects of the BBR-BAI combination on glucose and lipid metabolism and liver function in T2DM mice. Hematoxylin-eosin staining was employed to observe pathological changes in the colon tissue. The expression of claudin-1, zonula occludens-1 (ZO-1), and occludin in the colon tissue was determined by Western blot. Real-time quantitative polymerase chain reaction(Real-time PCR) was employed to assess the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in the colon tissue. The fecal microbiota composition and differential metabolites were analyzed by 16S rRNA sequencing and ultra-high performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry (UPLC-Q-TOF-MS), respectively. ResultsThe BBR-BAI combination lowered the FBG, HbA1c, and INS levels (P<0.05, P<0.01) and alleviated insulin resistance (P<0.01) in T2DM mice. Additionally, BBR-BAI elevated the levels of ZO-1, occludin, and claudin-1 (P<0.05, P<0.01) and down-regulated the expression levels of TNF-α, IL-1β, and IL-6 in the colon (P<0.05, P<0.01). The results of 16S rRNA sequencing showed that BBR-BAI increased the relative abundance of Ligilactobacillus, Phascolarctobacterium, and Akkermansia (P<0.05), while significantly decreasing the relative abundance of Alistipes, Odoribacter, and Colidextribacter (P<0.05). UPLC-Q-TOF-MS identified 28 differential metabolites, which were primarily involved in arachidonic acid metabolism and α-linolenic acid metabolism. ConclusionBBR-BAI can ameliorate T2DM due to internal accumulation of dampness-heat by modulating the relative abundance of various bacterial genera in the gut microbiota and the expression of fecal metabolites.

BACKGROUND:Bone relies on the close connection between blood vessels and bone cells to maintain its integrity.Bones are in a physiologically hypoxic environment.Therefore,the study of angiogenesis and osteogenesis in hypoxic environment is closer to the microenvironment in vivo. OBJECTIVE:To explore the influence of Wenshen Tongluo Zhitong(WSTLZT)formula on H-type bone microvascular endothelial cell/bone marrow mesenchymal stem cell co-culture system in hypoxia environment and its related mechanism. METHODS:Enzyme digestion method and flow sorting technique were used to isolate and identify H-type bone microvascular endothelial cells.Mouse bone marrow mesenchymal stem cells were isolated and obtained by bone marrow adhesion method.H-type bone microvascular endothelial cell/bone marrow mesenchymal stem cell hypoxic co-culture system was established using Transwell chamber and anoxic culture workstation.WSTLZT formula powder was used to intervene in each group at a mass concentration of 50 and 100 μg/mL.The angiogenic function of H-type bone microvascular endothelial cells in the co-culture system was evaluated by scratch migration test and tube formation test.The osteogenic differentiation ability of bone marrow mesenchymal stem cells in the co-cultured system was evaluated by alkaline phosphatase staining and alizarin red staining.The protein and mRNA expression changes of PDGF/PI3K/AKT signal axis related molecules in H-type bone microvascular endothelial cells in the co-cultured system were detected by Western Blotting and q-PCR,respectively. RESULTS AND CONCLUSION:(1)Compared with the normal oxygen group,the scratch mobility and new blood vessel length of H-type bone microvascular endothelial cells were significantly higher(P<0.05);the osteogenic differentiation capacity of bone marrow mesenchymal stem cells was higher(P<0.05);the expression of PDGF/PI3K/AKT axis-related molecular protein and mRNA increased(P<0.05)in the hypoxia group.(2)Compared with the hypoxia group,scratch mobility and new blood vessel length were significantly increased in the H-type bone microvascular endothelial cells(P<0.05);bone marrow mesenchymal stem cells had stronger osteogenic function(P<0.05);the expression of PDGF/PI3K/AKT axis-related molecular proteins and mRNA further increased(P<0.05)after treatment with different dose concentrations of WSTLZT formula.These findings conclude that H-type angiogenesis and osteogenesis under hypoxia may be related to the PDGF/PI3K/AKT signaling axis,and WSTLZT formula may promote H-type vasculo-dependent bone formation by activating the PDGF/PI3K/AKT signaling axis,thereby preventing and treating osteoporosis.
