This study aims to explore the mechanism of Jiaotai Pills in treating depression based on metabolomics and network pharmacology. The chemical constituents of Jiaotai Pills were identified by UHPLC-Orbitrap Exploris 480, and the targets of Jiaotai Pills and depression were retrieved from online databases. STRING and Cytoscape 3.7.2 were used to construct the protein-protein interaction network of core targets of Jiaotai Pills in treating depression and the "compound-target-pathway" network. DAVID was used for Gene Ontology(GO) function and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses of the core targets. The mouse model of depression was established with chronic unpredictable mild stress(CUMS) and treated with different doses of Jiaotai Pills. The behavioral changes and pathological changes in the hippocampus were observed. UHPLC-Orbitrap Exploris 120 was used for metabolic profiling of the serum, from which the differential metabolites and related metabolic pathways were screened. A "metabolite-reaction-enzyme-gene" network was constructed for the integrated analysis of metabolomics and network pharmacology. A total of 34 chemical components of Jiaotai Pills were identified, and 143 core targets of Jiaotai Pills in treating depression were predicted, which were mainly involved in the arginine and proline, sphingolipid, and neurotrophin metabolism signaling pathways. The results of animal experiments showed that Jiaotai Pills alleviated the depression behaviors and pathological changes in the hippocampus of the mouse model of CUMS-induced depression. In addition, Jiaotai Pills reversed the levels of 32 metabolites involved in various pathways such as arginine and proline metabolism, sphingolipid metabolism, and porphyrin metabolism in the serum of model mice. The integrated analysis showed that arginine and proline metabolism, cysteine and methionine metabolism, and porphyrin metabolism might be the key pathways in the treatment of depression with Jiaotai Pills. In conclusion, metabolomics combined with network pharmacology clarifies the antidepressant mechanism of Jiaotai Pills, which may provide a basis for the clinical application of Jiaotai Pills in treating depression.

OBJECTIVE: To assess the efficacy of Qingda Granule (QDG) in ameliorating hypertension-induced cardiac damage and investigate the underlying mechanisms involved. METHODS: Twenty spontaneously hypertensive rats (SHRs) were used to develope a hypertension-induced cardiac damage model. Another 10 Wistar Kyoto (WKY) rats were used as normotension group. Rats were administrated intragastrically QDG [0.9 g/(kg•d)] or an equivalent volume of pure water for 8 weeks. Blood pressure, histopathological changes, cardiac function, levels of oxidative stress and inflammatory response markers were measured. Furthermore, to gain insights into the potential mechanisms underlying the protective effects of QDG against hypertension-induced cardiac injury, a network pharmacology study was conducted. Predicted results were validated by Western blot, radioimmunoassay immunohistochemistry and quantitative polymerase chain reaction, respectively. RESULTS: The administration of QDG resulted in a significant decrease in blood pressure levels in SHRs (P<0.01). Histological examinations, including hematoxylin-eosin staining and Masson trichrome staining revealed that QDG effectively attenuated hypertension-induced cardiac damage. Furthermore, echocardiography demonstrated that QDG improved hypertension-associated cardiac dysfunction. Enzyme-linked immunosorbent assay and colorimetric method indicated that QDG significantly reduced oxidative stress and inflammatory response levels in both myocardial tissue and serum (P<0.01). CONCLUSIONS Both network pharmacology and experimental investigations confirmed that QDG exerted its beneficial effects in decreasing hypertension-induced cardiac damage by regulating the angiotensin converting enzyme (ACE)/angiotensin II (Ang II)/Ang II receptor type 1 axis and ACE/Ang II/Ang II receptor type 2 axis.

Loss of protein homeostasis is a hallmark of cellular senescence, and ribosome pausing plays a crucial role in the collapse of proteostasis. However, our understanding of ribosome pausing in senescent cells remains limited. In this study, we utilized ribosome profiling and G-quadruplex RNA immunoprecipitation sequencing techniques to explore the impact of RNA G-quadruplex (rG4) on the translation efficiency in senescent cells. Our results revealed a reduction in the translation efficiency of rG4-rich genes in senescent cells and demonstrated that rG4 structures within coding sequence can impede translation both in vivo and in vitro. Moreover, we observed a significant increase in the abundance of rG4 structures in senescent cells, and the stabilization of the rG4 structures further exacerbated cellular senescence. Mechanistically, the RNA helicase DHX9 functions as a key regulator of rG4 abundance, and its reduced expression in senescent cells contributing to increased ribosome pausing. Additionally, we also observed an increased abundance of rG4, an imbalance in protein homeostasis, and reduced DHX9 expression in aged mice. In summary, our findings reveal a novel biological role for rG4 and DHX9 in the regulation of translation and proteostasis, which may have implications for delaying cellular senescence and the aging process.

ObjectiveTo explore the clinical efficacy of Huangjin Shuangshen Jiawei （HJSSJW） granules in treating postoperative anxiety and depression after percutaneous coronary intervention （PCI） for coronary heart disease and the effects of this medicine on inflammatory cytokines. MethodNinety-four patients diagnosed with anxiety and depression after PCI were randomized into observation and control groups （47 cases） by the double-blind method. On the basis of conventional Western medical treatment， the observation group was treated with HJSSJW granules for 12 weeks， and the control group with the simulant of HJSSJW granules for 12 weeks. The two groups were compared in terms of Hamilton Anxiety and Depression Scales （HAMA-14， HAMD-24）， Pittsburgh Sleep Quality Inventory （PSQI）， Seattle Angina Score （SAQ）， TCM symptom scores， traditional Chinese medicine （TCM） symptom score and response rate， serum levels of hypersensitive-C reactive protein （hs-CPR）， tumor necrosis factor （TNF）-α， and interleukin （IL-6）， and incidence of major adverse cardiovascular events （MACEs） and adverse reactions. ResultAfter treatment， both groups showed declined scores of HAMA-14， HAMD-24， and PSQI （P<0.05， P<0.01） and the observation group had lower scores of HAMA-14， HAMD-24， and PSQI than the control group （P<0.01）. The scores of SAQ in both groups increased after treatment （P<0.01）， and the observation group had higher score of each dimension than the control group （P<0.05）. The TCM symptom scores decreased in both groups after treatment （P<0.01）， and they were lower in the observation group than in the control group （P<0.05）. The total response rate regarding TCM symptoms in the observation group was higher than that in the control group （χ²=9.225， P<0.01）. After treatment， the levels of hs-CPR， IL-6， and TNF-α became lowered in both groups （P<0.01）， and the observation group had lower levels of hs-CPR， IL-6， and TNF-α than the control group （P<0.05）. The incidence of MACEs in the observation group was lower than that in the control group during the 90 d of the follow-up period （χ²=4.242， P<0.05）. No adverse reactions associated with the use of HJSSJW granules were observed during the trial period. ConclusionHJSSJW granules can alleviate the bad mood， improve sleep， mitigate somatic symptoms， improve the quality of life， reduce inflammatory damage， and improve prognosis， being safe for clinical use in patients with postoperative anxiety and depression after PCI for coronary heart disease.

Objective:To introduce the application of highly selective arterial indocyanine green angiography (hereinafter referred to as highly selective arterial angiography) in the design of anterolateral thigh free flap.Methods:This study was a retrospective observational study. From November 2023 to April 2024, 29 patients with wounds in extremities which were repaired by anterolateral thigh free flaps designed under the assistance of highly selective arterial angiography and met the inclusion criteria were admitted to the Department of Hand Surgery and Department of Wound Repair Surgery of Suzhou Ruihua Orthopedic Hospital, including 26 males and 3 females, aged 16 to 71 years. The wound area after debridement ranged from 8.0 cm×4.5 cm to 27.0 cm×16.0 cm. During the surgery, highly selective arterial angiography was used to assist in flap design. The fluorescence development range of the source arteries or perforators of flaps was observed. The blood supply range of the source arteries or perforators of flaps was determined based on the fluorescence development of the skin, and the excision position of the flap was adjusted. The flap incision area ranged from 9.0 cm×6.0 cm to 29.0 cm×16.0 cm. During the surgery, the number of highly selective arterial angiography, the type of source artery of perforators for puncture, and changes in the excision position of flaps were observed and recorded. After surgery, the blood supply and survival of flaps, the healing of wounds and the survival of skin grafts in the flap donor sites, and the angiography-related complications were observed.Results:All the 32 flaps of 29 patients were successfully excised. The highly selective arterial angiography was performed 37 times, including 13 cases of puncture of the oblique branch of the lateral circumflex femoral artery, 6 cases of puncture of the descending branch, 8 cases of double puncture of the oblique and descending branches, and 2 cases of puncture of arteries from other branches. During the surgery, the excision position of 28 flaps did not change, the excision position of 3 flaps moved towards proximal extremity of the thigh, and the excision position of 1 flap moved towards distal extremity of the thigh. All the flaps survived successfully after the surgery, and there was no partial necrosis of the flaps at the proximal or distal ends. The wounds in the flap donor sites healed, and all skin grafts survived. No angiography-related complications occurred.Conclusions:Highly selective arterial angiography can be used to determine the blood supply range of the source artery and perforators of the anterolateral thigh free flaps during the surgery. It can evaluate the blood supply of flaps more intuitively and objectively. Its application in assisting flap design can avoid partial flap necrosis caused by unreasonable preoperative design to a certain extent, and it is safe and reliable.
