ObjectiveUlcerative colitis is a prevalent immunoinflammatory disease. Th17/Treg cell imbalance and gut microbiota dysregulation are key factors in ulcerative colitis pathogenesis. The actin cytoskeleton contributes to regulating the proliferation, differentiation, and migration of Th17 and Treg cells. Wdr63, a gene containing the WD repeat domain, participates in the structure and functional modulation of actin cytoskeleton. Recent research indicates that WDR63 may serve as a regulator of cell migration and metastasis via actin polymerization inhibition. This article aims to explore the effect of Wdr63 deletion on Th17/Treg cells and ulcerative colitis. MethodsWe constructed Wdr63-/- mice, induced colitis in mice using dextran sulfate sodium salt, collected colon tissue for histopathological staining, collected mesenteric lymph nodes for flow cytometry analysis, and collected healthy mouse feces for microbial diversity detection. ResultsCompared with wild-type colitis mice, Wdr63-/- colitis mice had a more pronounced shortening of colonic tissue, higher scores on disease activity index and histological damage index, Treg cells decreased and Th17 cells increased in colonic tissue and mesenteric lymph nodes, a lower level of anti-inflammatory cytokine IL-10, and a higher level of pro-inflammatory cytokine IL-17A. In addition, WDR63 has shown positive effects on maintaining intestinal microbiota homeostasis. It maintains the balance of Bacteroidota and Firmicutes, promoting the formation of beneficial intestinal bacteria linked to immune inflammation. ConclusionWdr63 deletion aggravates ulcerative colitis in mice, WDR63 inhibits colonic inflammation likely by regulating Th17/Treg balance and maintains intestinal microbiota homeostasis.

OBJECTIVE:Anterior cervical decompression and fusion is a classic surgical method for the treatment of degenerative cervical spondylosis.The use of nail plates increases the fusion rate and stability and indirectly leads to adjacent vertebral degeneration and postoperative dysphagia.In this paper,the clinical results and complications of ROI-CTM self-locking system and traditional cage combined with screw-plate internal fixation in the treatment of degenerative cervical spondylosis were compared by meta-analysis to provide evidence-based support for the selection of internal fixation methods in anterior cervical decompression and fusion. METHODS:CNKI,WanFang,VIP,PubMed,Cochrane Library,Web of Science,and Embase databases were searched for Chinese and English literature on the application of ROI-CTM self-locking system and fusion cage combined with screw plate internal fixation in the treatment of degenerative cervical spondylosis.The retrieval time range was from inception to July 2023.Two researchers selected the literature strictly according to the inclusion and exclusion criteria.The Cochrane bias risk tool was used to evaluate the quality of randomized controlled trials.Newcastle-Ottawa Scale was used to assess the quality of cohort studies.Meta-analysis was performed using RevMan 5.4 software.Outcome indicators included operation time,intraoperative blood loss,Japanese Orthopaedic Association score,Neck Disability Index,C2-C7 Cobb angle,fusion rate,incidence of adjacent vertebral degeneration,cage subsidence rate,and incidence of dysphagia. RESULTS:Thirteen articles were included,including eleven retrospective cohort studies and two randomized controlled trials,with 1 136 patients,569 in the ROI-C group,and 567 in the cage combined with the nail plate group.Meta-analysis results showed that the operation time(MD=-15.52,95%CI:-18.62 to-12.42,P<0.000 01)and intraoperative blood loss(MD=-24.53,95%CI:-32.46 to-16.61,P<0.000 01)in the ROI-C group and the fusion device combined with nail plate group.Postoperative adjacent segment degeneration rate(RR=0.40,95%CI:0.27-0.60,P<0.000 01)and postoperative total dysphagia rate(RR=0.18,95%CI:0.13-0.26),P<0.000 01)were statistically different.The two groups had no significant difference in Japanese Orthopaedic Association score,Neck Disability Index,C2-C7 Cobb angle,fusion rate,or cage subsidence rate(P≥0.05). CONCLUSION:Applying an ROI-CTM self-locking system and traditional cage combined with plate internal fixation in anterior cervical decompression and fusion can achieve satisfactory clinical results in treating degenerative cervical spondylosis.The operation of the ROI-CTM self-locking system is more straightforward.Compared with a cage combined with plate internal fixation,the ROI-CTM self-locking system can significantly reduce the operation time and intraoperative blood loss and has obvious advantages in reducing the incidence of postoperative dysphagia and adjacent segment degeneration.The ROI-CTM self-locking system is recommended for patients with skip cervical spondylosis and adjacent vertebral disease.However,given its possible high settlement rate,using a fusion cage combined with screw-plate internal fixation is still recommended for patients with degenerative cervical spondylosis with multiple segments and high-risk factors of fusion cage settlement,such as osteoporosis and vertebral endplate damage.

Objective To explore the risk factors for postoperative respiratory failure (RF) in patients with esophageal cancer, construct a predictive model based on the least absolute shrinkage and selection operator (LASSO)-logistic regression, and visualize the constructed model. Methods A retrospective analysis was conducted on patients with esophageal cancer who underwent surgical treatment in the Department of Thoracic Surgery, Sun Yat-sen University Cancer Center Gansu Hospital from 2020 to 2023. Patients were divided into a RF group and a non-RF (NRF) group according to whether RF occurred after surgery. Clinical data of the two groups were collected, and LASSO-logistic regression was used to optimize feature selection and construct the predictive model. The model was internally validated by repeated sampling 1000 times based on the Bootstrap method. Results A total of 217 patients were included, among which 24 were in the RF group, including 22 males and 2 females, with an average age of (63.33±9.10) years; 193 were in the NRF group, including 161 males and 32 females, with an average age of (62.14±8.44) years. LASSO-logistic regression analysis showed that the percentage of forced expiratory volume in one second/forced vital capacity (FEV1/FVC) to predicted value (FEV1/FVC%pred) [OR=0.944, 95%CI (0.897, 0.993), P=0.026], postoperative anastomotic fistula [OR=4.106, 95%CI (1.457, 11.575), P=0.008], and postoperative lung infection [OR=3.776, 95%CI (1.373, 10.388), P=0.010] were risk factors for postoperative RF in patients with esophageal cancer. Based on the above risk factors, a predictive model was constructed, with an area under the receiver operating characteristic curve of 0.819 [95%CI (0.737, 0.901)]. The Hosmer-Lemeshow test for the calibration curve showed that the model had good goodness of fit (P=0.527). The decision curve showed that the model had good clinical net benefit when the threshold probability was between 5% and 50%. Conclusion FEV1/FVC%pred, postoperative anastomotic fistula, and postoperative lung infection are risk factors for postoperative RF in patients with esophageal cancer. The predictive model constructed based on LASSO-logistic regression analysis is expected to help medical staff screen high-risk patients for early individualized intervention.

Lung cancer is the malignant tumor with the highest incidence and mortality rates globally. Current treatment methods for lung cancer primarily include surgery, chemotherapy, targeted therapy, and immunotherapy. However, the main limitations of these treatments are their side effects, the drug resistance, and the economic burden they impose. As a critical cancer pathway, the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling pathway regulates tumor occurrence and development through multiple mechanisms by influencing various downstream targets. Consequently, the JAK/STAT signaling pathway offers a promising avenue for lung cancer treatment research. Numerous studies have demonstrated that the JAK/STAT signaling pathway plays a key role in the proliferation and growth of lung cancer cells, angiogenesis, epithelial-mesenchymal transition (EMT), metabolic alterations, remodeling of the immune microenvironment, and the development of treatment resistance. Traditional Chinese medicine (TCM) has garnered increasing attention due to its minimal side effects, low economic burden, and its potential to enhance efficacy and reduce toxicity when used in conjunction with Western medicine. In addition to traditional Chinese medicine compounds, a growing number of Chinese medicine monomers have come into the spotlight because of their more targeted effects. Numerous studies investigating the regulation of the JAK/STAT signaling pathway by TCM in the treatment of lung cancer have demonstrated that TCM can inhibit the proliferation and invasion of lung cancer cells, tumor angiogenesis, and EMT, improve the inflammatory and immunosuppressive microenvironments, and enhance treatment sensitivity by intervening in the JAK/STAT signaling pathway, thereby impeding the progression of lung cancer. In recent years, the research on the regulation of this pathway by TCM in the treatment of lung cancer has been updated rapidly. However, the summary of these studies has not been updated in time. This review summarizes and reflects on the recent research findings regarding the regulation of the JAK/STAT signaling pathway by TCM to intervene in lung cancer from three aspects, introducing the JAK/STAT pathway, elaborating the mechanism of this pathway in lung cancer, and exploring the intervention of TCM in the treatment of lung cancer through this pathway, to provide more reference for the treatment of lung cancer in the future.

ObjectiveTo investigate the role of silent information regulatory protein (SIRT6)/hypoxia-inducible factor-1α (HIF-1α) pathway in regulating the reprogramming of glucose metabolism in ulcerative colitis (UC) and the mechanism of intervention of Shaoyaotang. MethodsForty-eight c57bL/6 mice were randomly divided into a blank group, a model group, a Mesalazine group (0.42 g·kg-1), a Shaoyaotang group (31.08 g·kg-1), an inhibitor group (OSS-128167, 50 mg·kg-1), and an inhibitor + Shaoyaotang group (50 mg·kg-1 OSS-128167 + 31.08 g·kg-1 Shaoyaotang). A UC model was established by the administration of 2.5% dextran sulfate sodium (DSS) solution for mice in other groups for 7 d, except for the blank group. The mice in each group were treated with saline, Mesalazine, Shaoyaotang, inhibitor, and inhibitor + Shaoyaotang, respectively, for 7 d. The mice were necropsied 24 h after the last administration of the drug. The blood was collected from the orbital region, and colon tissue was taken. Hematoxylin-eosin (HE) staining was used to observe the pathological changes in colon tissue. Enzyme-linked immunosorbent assay (ELISA) was employed to detect serum interleukin (IL)-10, IL-17, and IL-6 levels. A biochemical method was used to detect glucose and lactate dehydrogenase A (LDHA) levels. Immunohistochemistry (IHC) was employed to detect IL-22 and transforming growth factor-β1 (TGF-β1) levels in colon tissue, and Western blot and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) were used to detect relative protein and mRNA expressions of SIRT6, HIF-1α, and LDHA. ResultsCompared with those of the blank group, disease activity index (DAI) scores of mice in the model group and inhibitor group were significantly increased (P<0.01). The length of colon tissue was significantly shortened, and colon tissue was congested and eroded. The pathohistological scores were significantly increased (P<0.01). The levels of serum inflammatory factors IL-17 and IL-6 were significantly elevated, and the levels of IL-10 were significantly decreased (P<0.01). The protein expressions of IL-22 and TGF-β1 were significantly reduced in colon tissue (P<0.01). The relative protein and mRNA expressions of SIRT6 were significantly decreased (P<0.01), and the relative protein and mRNA expressions of HIF-1α and LDHA and the contents of glucose and lactate were significantly elevated (P<0.01). The level of inflammation in the colon of the mice in the inhibitor group was more severe than that in the model group (P<0.01). Compared with the model group, the Mesalazine group, the Shaoyaotang group, and the inhibitor + Shaoyaotang group showed reduced colonic injury, significant decrease in serum IL-17 and IL-6, significant increase in IL-10 (P<0.01), significant increase in the protein expressions of IL-22 and TGF-β1 in colon tissue (P<0.01), significant increase in the protein expressions of SIRT6 and the relative mRNA expressions (P<0.01), and significant reduction in the protein expressions of HIF-1α and LDHA, the relative mRNA expressions, and the contents of glucose and lactate (P<0.01). Compared with those in the Shaoyaotang group, the serum IL-17 and IL-6 were significantly increased, and IL-10 was significantly decreased in the inhibitor + Shaoyaotang group (P<0.01). The protein expressions of IL-22 and TGF-β1 in colon tissue were significantly decreased (P<0.01). The expressions of SIRT6 protein and the relative mRNA expressions were significantly decreased (P<0.01). The protein expressions of HIF-1α and LDHA, the relative mRNA expressions, and the contents of glucose and lactate were significantly elevated (P<0.01). However, the difference between the Shaoyaotang group and the Mesalazine group was not significant. ConclusionShaoyaotang can effectively treat DSS-induced mice with UC through the SIRT6/HIF-1α pathway, and its mechanism of action may be related to the regulation of the SIRT6/HIF-1α pathway and glucose metabolism reprogramming and the inhibition of glycolysis.

ObjectiveTo investigate the effects of different concentrations of Shaoyaotang-containing serum on lipopolysaccharide (LPS)-induced inflammation of human colorectal adenocarcinoma (Caco-2) cells by inhibiting apoptosis via activating the tumor necrosis factor (TNF) receptor superfamily member 6 (Fas)/Fas ligand (FasL) pathway. MethodsCaco-2 cells were allocated into blank, model (LPS, 10 mg·L-1), Shaoyaotang-containing serum (5%, 10%, 15%, 20%), and Fas inhibitor (KR-33493, 20 mmol·L-1) groups. Except the blank group, the other groups were stimulated with 10 mg·L-1 LPS for 24 h for the modeling of inflammation. After successful modeling, the blank, Fas inhibitor, and model groups were treated with blank serum, and the Shaoyaotang-containing serum groups were treated with the serum samples at corresponding concentrations for 24 h. The Fas inhibitor group was subjected to KR-33493 pretreatment for 1 h. Cell proliferation and viability were examined by the cell-counting kit-8 (CCK-8) method. The levels of interleukin (IL)-6, IL-1β, and TNF-α were measured by enzyme-linked immunosorbent assay. Apoptosis was detected by flow cytometry. The protein and mRNA levels of Fas, FasL, cysteinyl aspartate-specific proteinase (Caspase)-3, Caspase-9, B-cell lymphoma 2 (Bcl-2), and Bcl-2-associated X protein (Bax) were determined by Western blot and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), respectively. ResultsCompared with the blank group, the model group presented a decrease in cell survival rate (P<0.01). Compared with that in the model group, the cell survival rate showed no significant change in the 5% Shaoyaotang-containing serum group but increased in the 10%, 15%, and 20% Shaoyaotang-containing serum groups (P<0.01). Since there was no statistical difference between the 5% Shaoyaotang-containing serum group and the model group, 10%, 15%, and 20% Shaoyaotang-containing sera were selected for the follow-up study. Compared with the blank group, the model group showed risen levels of IL-6, IL-1β, and TNF-α (P<0.01), an increased apoptosis rate (P<0.01), up-regulated protein and mRNA levels of Fas, FasL, Caspase-3, Caspase-9, and Bax (P<0.01), and down-regulated protein and mRNA levels of Bcl-2 (P<0.01). Compared with the model group, the Fas inhibitor group and the 10%, 15%, and 20% Shaoyaotang-containing serum groups showed declined levels of IL-6, IL-1β, and TNF-α (P<0.01), decreased apoptosis rates (P<0.01), down-regulated protein and mRNA levels of Fas, FasL, Caspase-3, Caspase-9, and Bax (P<0.05, P<0.01), and up-regulated protein and mRNA levels of Bcl-2 (P<0.05, P<0.01). In addition, the 15% and 20% Shaoyaotang-containing serum groups had lower levels of IL-6, IL-1β, and TNF-α (P<0.05, P<0.01), lower apoptosis rates (P<0.05, P<0.01), lower protein and mRNA levels of Fas, FasL, Caspase-3, Caspase-9, and Bax (P<0.05, P<0.01), and higher protein and mRNA levels of Bcl-2 (P<0.05, P<0.01) than the 10% Shaoyaotang-containing serum group. ConclusionThe Shaoyaotang-containing serum can reduce the content of inflammatory factors in Caco-2 cells, down-regulate the protein and mRNA levels of Fas, FasL, Caspase-3, Caspase-9, and Bax, and up-regulate the protein and mRNA levels of Bcl-2 under the intervention of LPS by regulating the Fas/FasL pathway and inhibiting the apoptosis of intestinal epithelial cells in ulcerative colitis.

ObjectiveTo investigate the protective effect and mechanism of Shaoyaotang (SYD) on the lipopolysaccharide (LPS)-induced damage of tight junction proteins in the human colorectal adenocarcinoma (Caco-2) cell model of inflammation via the Ras homolog gene family member A (RhoA)/Rho-associated coiled-coil forming protein kinase (ROCK) pathway. MethodsCaco-2 cells were grouped as follows: Blank, model (LPS, 10 mg·L-1), SYD-containing serum (10%, 15%, and 20%), and inhibitor (Fasudil, 25 μmol·L-1). After 24 hours of intervention, the cell viability in each group was examined by the cell-counting kit 8 (CCK-8) method. Enzyme-linked immunosorbent assay was employed to determine the levels of endothelin-1 (ET-1), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were employed to determine the mRNA and protein levels, respectively, of RhoA, ROCK2, claudin-5, and zonula occludens-1 (ZO-1) in cells of each group. ResultsCompared with the blank group, the model group showcased a marked reduction in the cell viability (P<0.01), elevations in the levels of ET-1, TNF-α, IL-1β, and IL-6 (P<0.01), declines in both mRNA and protein levels of ZO-1 and claudin-5 (P<0.01), and rises in mRNA and protein levels of RhoA and ROCK2 (P<0.01). Compared with the model group, the Shaoyaotang-containing serum (10%, 15%, and 20%) groups had enhanced cell viability (P<0.01), lowered levels of ET-1, TNF-α, IL-1β, and IL-6 (P<0.01), up-regulated mRNA and protein levels of ZO-1 and claudin-5 (P<0.05, P<0.01), and down-regulated mRNA and protein levels of RhoA and ROCK2 (P<0.01). Moreover, the inhibitor group and the 15% and 20% Shaoyaotang-containing serum groups had lower levels of ET-1, TNF-α, IL-1β, and IL-6 (P<0.05, P<0.01), higher mRNA and protein levels of ZO-1 and claudin-5 (P<0.05, P<0.01), and lower mRNA and protein levels of RhoA and ROCK2 (P<0.05, P<0.01) than the 10% Shaoyaotang-containing serum group. ConclusionThe Shaoyaotang-containing serum can lower the levels of LPS-induced increases in levels of inflammatory cytokines and endothelin to ameliorate the damage of tight junction proteins of the Caco-2 cell model of inflammation by regulating the expression of proteins in the RhoA/ROCK pathway.

ObjectiveTo investigate the effect of Shaoyaotang on T helper cell 17/regulatory T lymphocyte(Th17/Treg) cell balance in ulcerative colitis and decipher the intervention mechanism based on glucose metabolism reprogramming. MethodsThe mouse model of ulcerative colitis was established by the dextran sulfate sodium (DSS) method. Forty-eight C57BL/6 mice were randomly allocated into normal, model, Western drug control (mesalazine, 0.39 g·kg-1·d-1), Shaoyaotang (15.54 g·kg-1·d-1), inhibitor (2-deoxy-D-glucose, 2-DG, 100 mg·kg-1·d-1), and inhibitor (2-DG, 100 mg·kg-1·d-1) + Shaoyaotang (15.54 g·kg-1·d-1) groups. Mice were administrated with the corresponding drugs by gavage for 7 days. The general conditions and the colon injury degree were observed 24 h after the last administration. The expression of interleukin (IL)-10 and IL-17 in the colon tissue was detected by immunohistochemical staining. Western blot and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) were performed to determine the protein and mRNA levels, respectively, of hypoxia-inducing factor-1α (HIF-1α), lactate dehydrogenase (LDHA), and hexokinase 2 (HK2) in the colon tissue. Th17/Treg cell differentiation was detected by flow cytometry. Enzyme-linked immunosorbent assay was employed to measure the levels of lactic acid and glucose in the colon tissue and IL-10, IL-17, and IL-6 in the serum. ResultsCompared with the normal group, the model group showed decreases in body weight and disease activity index (DAI) (P<0.05), elevations in levels of HIF-1α, LDHA, HK2, IL-17, IL-6, Th17 cells, lactic acid, and glucose in the colon tissue (P<0.05), and declines in the levels of of IL-10 and Treg cells (P<0.05). Compared with the model group, the drug administration groups showed increases in body weight and DAI (P<0.05), declines in levels of HIF-1α, LDHA, HK2, IL-17, IL-6, Th17 cells, lactic acid, and glucose in the colon tissue (P<0.05), and rises in levels of IL-10 and Treg cells (P<0.05). Shaoyaotang+2-DG group had the most obvious effect. ConclusionShaoyaotang can relieve diarrhea and bloody stool in mice with ulcerative colitis by restoring the Th17/Treg cell balance via regulation of glucose metabolism reprogramming, thus playing a role in the treatment of ulcerative colitis.
