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.

ObjectiveTo elucidate the underlying mechanism through which Zhuluan decoction suppresses excessive autophagy in human ovarian granulosa cells (KGN) and ameliorates premature ovarian insufficiency (POI) via the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway. MethodsThe optimal concentration of cyclophosphamide for inducing a POI model in KGN cells was identified via the cell counting kit-8 (CCK-8) assay. Subsequently, the impacts of varying concentrations of Zhuluan decoction-containing serum on the viability of the KGN cell model were assessed. After the optimal drug concentration was determined, KGN cells were categorized into the following groups: blank control (20% blank serum), model (20% blank serum + 5 μmol·L-1 cyclophosphamide), Zhuluan decoction-containing serum (20% Zhuluan decoction-containing serum + 5 μmol·L-1 cyclophosphamide), autophagy inhibitor (20% blank serum + 5 μmol·L-1 cyclophosphamide + 20 μmol·L-1 chloroquine phosphate), autophagy inhibitor + Zhuluan decoction-containing serum (20% Zhuluan decoction-containing serum + 5 μmol·L-1 cyclophosphamide + 20 μmol·L-1 chloroquine phosphate), and estradiol valerate (20% estradiol valerate-containing serum + 5 μmol·L-1 cyclophosphamide). Following 48 hours of incubation, flow cytometry was utilized to measure the apoptosis rate of KGN cells in each group. Western blotting was employed to quantify the protein levels of PI3K, phosphorylated (p)-Akt, Akt, p-mTOR, and mTOR, along with the expression levels of autophagy-related proteins such as Beclin1, autophagy-related 5 homolog (ATG5), and microtubule-associated protein 1 light chain 3 (LC3), in each group. Additionally, monodansylcadaverine (MDC) staining was performed to evaluate the extent of autophagy in each group. ResultsIncubation of KGN cells with 5 μmol·L-1 cyclophosphamide for 48 h successfully established a POI model, marked by a significant inhibition of KGN cell proliferation. Notably, the inhibitory effect of cyclophosphamide on KGN cell proliferation exhibited a positive correlation with its concentration. Zhuluan decoction-containing serum at 20% and 30% promoted cell proliferation and mitigated the inhibitory effect of cyclophosphamide on KGN cell proliferation, with comparable therapeutic efficacy observed at both concentrations. Compared with the blank control group, the model group displayed an elevated apoptosis rate (P<0.01), reduced protein levels of PI3K, p-Akt, and p-mTOR (P<0.01), increased protein levels of Beclin1, LC3, and ATG5 (P<0.01), no significant alterations in the protein levels of Akt and mTOR, and an enhanced MDC autophagy fluorescence intensity (P<0.01). In comparison to that the model group, the apoptosis rates in the blank control group, model group, Zhuluan decoction-containing serum group, autophagy inhibitor group, autophagy inhibitor + Zhuluan decoction-containing serum group, and estradiol valerate group all reduced (P<0.05, P<0.01), with the most pronounced reduction observed in the autophagy inhibitor + Zhuluan decoction-containing serum group. The protein levels of PI3K, p-Akt, and p-mTOR were higher in other groups than in the model group (P<0.05, P<0.01), being the highest in the autophagy inhibitor + Zhuluan decoctio-containing serum group (P<0.01). The protein levels of Beclin1 and ATG5 were lower in other groups than in the model group (P<0.05, P<0.01). The expression level of LC3 declined in the Zhuluan decoction-containing serum group and the estradiol valerate group (P<0.05, P<0.01), while it decreased without statistical significance in the autophagy inhibitor group and the autophagy inhibitor + Zhuluan decoction-containing serum group. ConclusionZhuluan decoction may activate the PI3K/Akt/mTOR pathway to inhibit excessive autophagy and counteract the detrimental effects of cyclophosphamide on the KGN cell model, thus managing POI.

ObjectiveTo investigate the mechanism of ferroptosis mediated by long-chain acyl-CoA synthetase 4 (ACSL4) signalling pathway in rats with coronary heart disease with blood stasis syndrome and the intervention effect of Xuefu Zhuyutang. MethodsSPF male SD rats were randomly divided into normal group, sham-operation group, model group, trimetazidine group (5.4 mg·kg-1), low-, medium-, and high-dose group (3.51, 7.02,14.04 g·kg-1) of Xuefu Zhuyutang. The coronary artery left anterior descending ligation method was used to prepare a model of coronary heart disease with blood stasis syndrome, and continuous treatment for 7 d was conducted, while the sham-operation group was only threaded and not ligated. The general macroscopic symptoms of the rats were observed, and indicators such as electrocardiogram, echocardiography, and blood rheology were detected. The pathological morphology of myocardial tissue was observed by hematoxylin-eosin (HE) staining, and the changes in mitochondria in myocardial tissue were observed by transmission electron microscopy. The level of iron deposition in myocardial tissue was observed by Prussian blue staining. The levels of 12-hydroxyeicosatetraenoic acid (12-HETE) and 15-HETE were detected in serum by enzyme-linked immunosorbent assay. A biochemical colourimetric assay was used to detect the levels of Fe2+, lipid peroxidation (LPO), glutathione (GSH), and T-GSH/glutathione disulfide (GSSG) in myocardial tissue. DCFH-DA fluorescence quantitative assay was employed to detect the levels of reactive oxygen species (ROS). Western blot and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was adopted to detect the protein and mRNA expressions of glutathione peroxidase 4 (GPX4), ferritin heavy chain 1 (FTH1), ACSL4, and ly-sophosphatidylcholine acyltransferase3 (LPCAT3) in myocardial tissue. ResultsCompared with those in the normal group, the rats in the model group were poor in general macroscopic symptoms. The electrocardiogram showed widened QRS wave amplitude and increased voltage, bow-back elevation of the ST segments, elevated T waves, J-point elevation, and accelerated heart rate. Echocardiography showed a significant reduction in left ventricular ejection fraction (LVEF) and left ventricular fraction shortening (LVFS) (P<0.01). Blood rheology showed that the viscosity of the whole blood (low, medium, and high rate of shear) was significantly increased (P<0.01). HE staining showed an abnormal structure of myocardial tissue. There was a large area of myocardial necrosis and inflammatory cell infiltration and a large number of connective tissue between myocardial fibers. Transmission electron microscopy showed that the mitochondria were severely atrophy or swelling. The cristae were reduced or even broken, and the matrix was flocculent or even vacuolated. Prussian blue staining showed that there were a large number of iron-containing particles, and the iron deposition was obvious. The content of 12-HETE and 15-HETE in the serum was significantly increased (P<0.01). The content of Fe2+, LPO, and ROS in myocardial tissue was significantly increased (P<0.01). The content of GSH was significantly decreased (P<0.01), and T-GSH/GSSG was decreased (P<0.01). The protein and mRNA expressions of GPX4 and FTH1 in myocardial tissue were both significantly decreased (P<0.05, P<0.01), while those of ACSL4 and LPCAT3 increased significantly (P<0.01). Compared with the model group, the general macroscopic symptoms and electrocardiogram results of rats in low-, medium- and high-dose groups of Xuefu Zhuyutang were alleviated, and the differences in LVEF/LVFS ratios were all significantly increased (P<0.05, P<0.01). The differences in whole-blood viscosity (low, medium, and high rate of shear) were all significantly decreased (P<0.01). The results of HE staining and transmission electron microscopy showed that the morphology, structure, and mitochondria of cardiomyocytes were improved. The content of 12-HETE and 15-HETE in serum was reduced to different degrees in low-, medium-, and high-dose groups of Xuefu Zhuyutang (P<0.05, P<0.01). The content of Fe2+, LPO, and ROS was significantly reduced in the medium- and high-dose groups of Xuefu Zhuyutang (P<0.05, P<0.01), and the content of GSH and T-GSH/GSSG was significantly increased (P<0.05, P<0.01). The protein and mRNA expressions of GPX4 and FTH1 were significantly increased to varying degrees in the medium- and high-dose groups of Xuefu Zhuyutang (P<0.05, P<0.01), and ACSL4 and LPCAT3 were decreased to different degrees in the low-, medium-, and high-dose groups of Xuefu Zhuyutang (P<0.05, P<0.01). ConclusionXuefu Zhuyutang can regulate iron metabolism and anti-lipid oxidation reaction to mediate ferroptosis through the ACSL4 signalling pathway, thus exerting a protective effect on rats with coronary heart disease with blood stasis syndrome.

ObjectiveBased on ultra performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry(UPLC-Q-Orbitrap-MS), to identify the in vivo and in vitro chemical components of total phenolic acids in Gei Herba(TPAGH), and to clarify the pharmacological effects and potential mechanisms of the effective part in promoting acute wound healing and inhibiting scar formation. MethodsUPLC-Q-Orbitrap-MS was used to identify the chemical components of TPAGH and ingredients absorbed in vivo after topical administration. A total of 120 ICR mice were randomly divided into the model group, recombinant human epidermal growth factor(rhEGF) group(4 mg·kg-1), and low, medium, and high dose groups of TPAGH(3.5, 7, 14 mg·kg-1), with 24 mice in each group. A full-thickness skin excision model was constructed, and each administration group was coated with the drug at the wound site, and the model group was treated with an equal volume of normal saline, the treatment was continued for 30 days, during which 8 mice from each group were sacrificed on days 6, 12, and 30. The healing of the wounds in the mice was observed, and histopathological changes in the skin tissues were dynamically observed by hematoxylin-eosin(HE), Masson, and Sirius red staining, and enzyme-linked immunosorbent assay(ELISA) was used to dynamically measure the contents of interleukin-6(IL-6), tumor necrosis factor-α(TNF-α), vascular endothelial growth factor A(VEGFA), matrix metalloproteinase(MMP)-3 and MMP-9 in skin tissues. Network pharmacology was used to predict the targets related to the promotion of acute wound healing and the inhibition of scar formation by TPAGH, and molecular docking of key components and targets was performed. Gene Ontology(GO) biological process analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were carried out for the related targets, so as to construct a network diagram of herbal material-compound-target-pathway-pharmacological effect-disease for further exploring its potential mechanisms. ResultsA total of 146 compounds were identified in TPAGH, including 28 phenylpropanoids, 31 tannins, 23 triterpenes, 49 flavonoids, and 15 others, and 16 prototype components were found in the serum of mice. Pharmacodynamic results showed that, compared with the model group, the TPAGH groups showed a significant increase in relative wound healing rate and relative scar inhibition rate(P<0.05), and the number of new capillaries, number of fibroblasts, number of new skin appendages, epidermal regeneration rate, collagen deposition ratio, and Ⅲ/Ⅰ collagen ratio in the tissue were significantly improved(P<0.05, 0.01), the levels of IL-6, TNF-α, MMP-3 and MMP-9 in the skin tissues were reduced to different degrees, while the level of VEGFA was increased. Network pharmacology analysis screened 10 core targets, including tumor protein 53(TP53), sarcoma receptor coactivator(SRC), protein kinase B(Akt)1, signal transducer and activator of transcription 3(STAT3), epidermal growth factor receptor(EGFR) and so on, participating in 75 signaling pathways such as advanced glycation end-products(AGE)-receptor for AGE(AGE/RAGE) signaling pathway, phosphatidylinositol 3-kinase(PI3K)/Akt signaling pathway, mitogen-activated protein kinase(MAPK) signaling pathway. Molecular docking confirmed that the key components genistein, geraniin, and casuariin had good binding ability to TP53, SRC, Akt1, STAT3 and EGFR. ConclusionThis study comprehensively reflects the chemical composition of TPAGH and the absorbed components after topical administration through UPLC-Q-Orbitrap-MS. TPAGH significantly regulates key indicators of skin healing and tissue reconstruction, thereby clarifying its role in promoting acute wound healing and inhibiting scar formation. By combining in vitro and in vivo component identification with network pharmacology, the study explores how key components may bind to targets such as TP53, Akt1 and EGFR, exerting therapeutic effects through related pathways such as immune inflammation and vascular regeneration.

Pulmonary complications, the most common postoperative complications of lung cancer, not only affect the quality of life of the patients after surgery but also increase the prognostic risks of postoperative recurrence and metastasis, threatening the life safety. At present, a multidisciplinary model of diagnosis and rehabilitation with integrated traditional Chinese medicine (TCM) and Western medicine has been initially formed under the guidance of the concept of rapid rehabilitation post operation for lung cancer. However, the treatment that only aims at shortening hospital stay and reducing the incidence of postoperative complications does not pay enough attention to the postoperative functional rehabilitation of the lung and the impact of follow-up adjuvant therapy, which affects the completeness of rehabilitation. This paper classifies the typical postoperative symptoms and manifestations of lung cancer into five groups: Lung system, emotion, digestive tract, pain, and nerve. On this basis, this paper summarizes the three core pathogeneses of postoperative complications of lung cancer as failure of Qi to ascend and descend leading to insecurity of defensive exterior, vessel block leading to Qi stagnation and fluid retention, and lung Qi deficiency leading to spleen and kidney deficiency. Accordingly, this paper proposes the treatment principle of protecting healthy Qi and treating Qi with the core of descending-tonifying-ascending-dispersing Qi and puts forward three treatment methods. The first is replenishing Qi and consolidating exterior, and expelling phlegm and regulating lung. The second is replenishing Qi and promoting blood flow to resolve stasis and relieving pain. The third is replenishing Qi and tonifying lung, and invigorating spleen and tonifying kidney. Furthermore, this paper elaborates on the pathogenesis and treatment principles of four common postoperative complications: Lung infection, pleural effusion, atelectasis, and bronchopleural fistula. On the basis of Western medical treatment, the TCM treatment characteristics of treating symptoms in the acute phase and eradicating the root cause in the chronic phase should be played. While dispelling the pathogen, measures should be taken to protect the healthy Qi, including tonifying lung Qi, regulating spleen Qi, and replenishing kidney Qi. This study summarizes the pathogenesis and treatment strategy of common postoperative complications of lung cancer according to the principle of protecting healthy Qi and treating Qi, aiming to provide guidance for the future treatment of postoperative complications of lung cancer.

Urinary incontinence is a common complication following robot-assisted radical prostatectomy (RARP). Urethral length has been identified as a factor affecting postoperative continence recovery. In this meta-analysis, we examined the association between use of the maximal urethral length preservation (MULP) technique and postoperative urinary continence in patients undergoing RARP. We conducted a comprehensive search of PubMed, Web of Science, Embase, and the Cochrane Library up to December 31, 2023. The quality of the literature was assessed using the Newcastle-Ottawa Scale. A random-effects meta-analysis was performed to synthesize data and calculate the odds ratio (OR) from eligible studies on continence and MULP. Six studies involving 1869 patients met the eligibility criteria. MULP was positively associated with both early continence (1 month after RARP; Z = 3.62, P = 0.003, OR = 3.10, 95% confidence interval [CI]: 1.68-5.73) and late continence (12 months after RARP; Z = 2.34, P = 0.019, OR = 2.10, 95% CI: 1.13-3.90). Oncological outcomes indicated that MULP did not increase the overall positive surgical margin rate or the positive surgical margin status at the prostate apex (both P > 0.05). In conclusion, the use of the MULP technique in RARP significantly improved both early and late postoperative continence outcomes without compromising oncological outcomes.

Male factors contribute to 50% of infertility cases, with 20%-30% of cases being solely attributed to male infertility. Helicase for meiosis 1 ( HFM1 ) plays a crucial role in ensuring proper crossover formation and synapsis of homologous chromosomes during meiosis, an essential process in gametogenesis. HFM1 gene mutations are associated with male infertility, particularly in cases of non-obstructive azoospermia and severe oligozoospermia. However, the effects of intracytoplasmic sperm injection (ICSI) in HFM1 -related infertility cases remain inadequately explored. This study identified novel biallelic HFM1 variants through whole-exome sequencing (WES) in a Chinese patient with severe oligozoospermia, which was confirmed by Sanger sequencing. The pathogenicity of these variants was assessed using real-time quantitative polymerase chain reaction (RT-qPCR) and immunoblotting, which revealed a significant reduction in HFM1 mRNA and protein levels in spermatozoa compared to those in a healthy control. Transmission electron microscopy revealed morphological abnormalities in sperm cells, including defects in the head and flagellum. Despite these abnormalities, ICSI treatment resulted in a favorable fertility outcome for the patient, indicating that assisted reproductive techniques (ART) can be effective in managing HFM1 -related male infertility. These findings offer valuable insights into the management of such cases.
