ObjectiveTo explore the effect and mechanism of Taishan Panshi powder (TSPSP) on inhibiting oxidative stress injury in human chorionic trophoblast cells (HTR-8/SVneo), and to uelucidate the underlying mechanism of TSPSP in the treatment of spontaneous abortion (SA). MethodsGene differential analysis of SA was performed using the Gene Expression Omnibus (GEO) database and correlated with oxidative stress. Network pharmacology was employed to screen the active components of TSPSP, and a "Chinese medicine-component-target-disease" network was constructed to predict the mechanism of action of TSPSP. For in vitro validation experiments, HTR-8/SVneo cells were divided into blank group, model group, TSPSP-containing serum 2.5%, 5%, 10% groups, and nuclear factor E2-related factor 2 (Nrf2) inhibitor group (ML385, 30 μmol·L-1). Except for the blank group, other groups were stimulated with 150 μmol·L-1 H2O2 for 3 h to establish a cell oxidative stress injury model. After successful modeling, the blank group and model group were given 10% blank serum, each TSPSP-containing serum group was treated with the corresponding concentration of drug-containing serum, and the Nrf2 inhibitor group was additionally given 30 μmol·L-1 ML385 on the basis of 10% TSPSP-containing serum. All groups of cells were continuously cultured under the above conditions for 24 h, and then samples were collected for subsequent detection. Cell viability in each group was detected by CCK-8 assay. Cell migration rate was detected by scratch test. The contents of malondialdehyde (MDA), Fe2+, and Glutathione (GSH) were detected by enzyme-linked immunosorbent assay (ELISA). Intracellular reactive oxygen species (ROS) level was detected by a fluorescent probe (DCF-DA). The protein and mRNA expression levels of Kelch-like ECH-associated protein 1 (KEAP1), Nrf2, and forkhead box protein O3 (FoxO3) in cells were detected by immunofluorescence (IF) and real-time quantitative polymerase chain reaction (Real-time PCR). The protein expression levels of KEAP1, Nrf2, FoxO3, Glutathione peroxidase 4 (GPX4), and superoxide dismutase (SOD) in cells were detected by Western blot. ResultsThe GSE76862 and GSE22490 datasets were obtained from the GEO database. Differential gene analyses showed that the KEAP1, Nrf2, and FoxO3 genes were all associated with the disease. After matching with the oxidative stress pathway, nine significantly differential pathways were identified (P<0.05), among which three contained the target genes Nrf2 and FoxO3. A total of 246 active ingredient targets of TSPSP and 2 804 SA-related targets were obtained through network pharmacology, and 154 potential action targets were obtained after taking the intersection. Topological analysis showed that targets such as KEAP1 and Nrf2 exhibited high degree values. GO and KEGG enrichment analyses indicated that the intersection targets were mainly involved in oxidative stress response, FOXO and MAPK signaling pathways, etc. In in vitro experiments, compared with the blank group, the cell viability in the model group was significantly decreased (P<0.01). Compared with the model group, the cell viability in each TSPSP-containing serum group was significantly increased (P<0.01). Compared with the 10% TSPSP-containing serum group, the cell viability in the ML385 group decreased to approximately 70% (P<0.01). Compared with the blank group, the model group showed significantly increased contents of MDA, Fe2+, and ROS, decreased GSH expression (P<0.01), significantly reduced cell migration rate (P<0.01), and increased protein and mRNA expression levels of KEAP1 and FoxO3 (P<0.01), while decreased protein and mRNA expression levels of Nrf2, GPX4, and SOD (P<0.01). Compared with the model group, each TSPSP-containing serum group showed significantly decreased contents of MDA, Fe²⁺, and ROS, increased GSH expression (P<0.01), significantly increased migration rate (P<0.01), significantly decreased protein and mRNA expression levels of KEAP1 and FoxO3 (P<0.05, P<0.01), and significantly increased protein and mRNA expression levels of Nrf2, GPX4, and SOD (P<0.05, P<0.01). Compared with the 10% TSPSP-containing serum group, the ML385 group showed reversed trends in all indicators (P<0.05, P<0.01). ConclusionTSPSP can inhibit H2O2-induced oxidative stress injury of trophoblast cells, and its mechanism of action may be related to the drug activating the KEAP1/Nrf2/FoxO3 signaling pathway.

Chemotherapy-induced peripheral neurotoxicity (CIPN) is a severe dose-limiting adverse event of chemotherapy. Presently, the mechanism underlying the induction of CIPN remains unclear, and no effective treatment is available. In this study, through metabolomics analyses, we found that nab-paclitaxel therapy markedly increased serum serotonin [5-hydroxtryptamine (5-HT)] levels in both cancer patients and mice compared to the respective controls. Furthermore, nab-paclitaxel-treated enterochromaffin (EC) cells showed increased 5-HT synthesis, and serotonin-treated Schwann cells showed damage, as indicated by the activation of CREB3L3/MMP3/FAS signaling. Venlafaxine, an inhibitor of serotonin and norepinephrine reuptake, was found to protect against nerve injury by suppressing the activation of CREB3L3/MMP3/FAS signaling in Schwann cells. Remarkably, venlafaxine was found to significantly alleviate nab-paclitaxel-induced CIPN in patients without affecting the clinical efficacy of chemotherapy. In summary, our study reveals that EC cell-derived 5-HT plays a critical role in nab-paclitaxel-related neurotoxic lesions, and venlafaxine co-administration represents a novel approach to treating chronic cumulative neurotoxicity commonly reported in nab-paclitaxel-based chemotherapy.

Objective:To evaluate the short-term and long-term outcomes of patients with locally advanced low rectal cancer who achieved clinical complete response (cCR) or near-clinical complete response (near-cCR) after neoadjuvant chemoradiotherapy (nCRT) and then underwent local excision.Methods:This was a descriptive case series study. Clinical data of patients with low rectal cancer who received neoadjuvant therapy, achieved cCR or near-cCR, underwent local excision, and had complete postoperative follow-up data were retrospectively analyzed. The study period was from May, 2015 to October, 2024, and the patients were treated at Fujian Medical University Union Hospital. Indications for local excision in this study were as follows: pathologically confirmed rectal adenocarcinoma, with the lower edge of the tumor ≤ 6 cm from the anal verge; maximum diameter of the lesion ≤ 2 cm after nCRT; no regional lymph node metastasis detected by transrectal endoscopic ultrasound (ERUS), pelvic magnetic resonance imaging (MRI), or positron emission tomography-computed tomography (PET-CT) after nCRT; MRI showing fibrosis of the primary lesion with a small amount of high signal on diffusion-weighted imaging (DWI), consistent with ymrT0-1 stage; serum carcinoembryonic antigen level within the normal range (< 5 μg/L) after nCRT; complicated with severe underlying diseases such as cardiovascular and cerebrovascular diseases and assessed as unable to tolerate radical surgery through comprehensive evaluation; and signed informed consent for local excision. The contraindications were: colonoscopic pathology indicating poorly differentiated adenocarcinoma or signet ring cell carcinoma; suspected lateral lymph node metastasis before neoadjuvant therapy; patients with residual lesions exceeding 3 cm in range after treatment. A total of 153 patients were included in this study, including 84 males and 69 females. The median age was 62 years, and the median distance from the tumor to the anal verge after neoadjuvant therapy was 4.0 cm. The short-term efficacy indicators of this study included postoperative complications of local excision and postoperative pathological results, and the long-term efficacy indicators included oncological prognosis (3-year cumulative local recurrence rate, 3-year cumulative distant metastasis rate, 3-year progression-free survival, and 3-year overall survival) and anal function at 1 year after surgery evaluated using the Low Anterior Resection Syndrome (LARS) scale where the total score is 42 points such that 0-20 points indicate no LARS, 21-29 points indicate mild LARS, and 30-42 points indicate severe LARS.Results:Postoperative pathology showed 122 cases (79.7%) of ypT0 stage, 10 cases (6.5%) of ypT1 stage, 18 cases (11.8%) of ypT2 stage, and 3 cases (2.0%) of ypT3 stage. The incidence of surgery-related complications was 42.5% (65/153), and the main complications included perianal pain (39.9%, 61/153), intestinal wall incision dehiscence (21.6%, 33/153), and intestinal wall incision infection (18.3%, 28/153). The proportion of patients who received hypofractionated radiotherapy before surgery and developed intestinal wall incision dehiscence was 65.2% (15/23), which was higher than that in the conventional long-course (13.6%, 16/118) and short-course radiotherapy groups (16.7%,2/12) (χ 2=30.55, P<0.001); of the 20 patients who received additional immunotherapy before surgery, 13 developed intestinal wall incision dehiscence was 65.0%, which was higher than that in the group without additional immunotherapy [15.0%(20/133),χ 2=25.66, P<0.001]. The median follow-up time of the entire group was 35.4 months. During the follow-up period, there were 9 cases of postoperative local recurrence, with a 3-year cumulative local recurrence rate of 7.9% and 5 cases of distant metastasis, with a 3-year cumulative distant metastasis rate of 5.0%. The 3-year progression-free survival rate was 89.0%, and the 3-year overall survival rate was 95.9%. At 1 year after surgery, 10 cases (10.5%, 10/95) had severe anal dysfunction, and the median LARS score of the entire group was 5.0 (range: 0-41.0) points. Conclusions:For patients with locally advanced low rectal cancer who achieve cCR or near-cCR after neoadjuvant therapy, local excision results in favorable oncological prognosis and anal function preservation effects; however, the incidence of complications is relatively high.
