The concept of "qi deficiency with stagnation" refers to a pathological state characterized by the depletion of primordial qi， impaired qi transformation， and the development of internal stagnation. Under the cyclic chemotherapy regimen in oncology， chemotherapy-induced myelosuppression follows a progressive pathological course from qi deficiency to increasing stagnation. This sequential evolution from mild to severe myelosuppression closely aligns with the dynamic syndrome differentiation and treatment framework of "qi deficiency with stagnation". "Qi deficiency" reflects the gradual depletion of qi， blood， and essence， while "stagnation" refers to the accumulation of phlegm， turbid dampness， and blood stasis. These two components interact reciprocally， forming a vicious cycle where deficiency leads to stagnation， and stagnation further damages the healthy qi. In the early stage of mild myelosuppression， chemotoxicity begins to accumulate in the bone marrow， leading to qi consumption， blood deficiency， yin injury， and the gradual formation of turbid phlegm and damp stagnation. In the advanced stage of severe myelosuppression， the accumulation of toxicity causes qi sinking， exhaustion of essence， and marrow depletion， along with blood stasis obstructing the collaterals. Treatment strategies should be based on syndrome differentiation， with an emphasis on assessing the severity of the condition， balancing deficiency and excess， and achieving both symptomatic relief and root cause resolution.

This study aims to delve into the influences and underlying mechanisms of Banxia Xiexin Decoction(BXD) on the proliferation, apoptosis, invasion, and migration of colon cancer cells. Firstly, the components of BXD in blood were identified by UPLC-MS/MS, and subsequently the content of these components were determined by HPLC. Then, different concentrations of BXD were used to treat both the normal intestinal epithelial cells(NCM460) and the colon cancer cells(HT29 and HCT116). The cell viability and apoptosis were examined by the cell counting kit-8(CCK-8) and flow cytometry, respectively. Western blot was employed to determine the expression of the apoptosis regulators B-cell lymphoma-2(Bcl-2) and Bcl-2-associated X(Bax). The cell wound healing assay and Transwell assay were employed to measure the cell migration and invasion, respectively. Additionally, Western blot was employed to determine the expression levels of epithelial-mesenchymal transition(EMT)-associated proteins, including epithelial cadherin(E-cadherin), neural cadherin(N-cadherin), and vimentin. The protein and mRNA levels of the factors in the poly(ADP-ribose) glycohydrolase(PARG)/poly(ADP-ribose) polymerase 1(PARP1)/nuclear factor kappa-B p65(NF-κB p65) signaling pathway were determined by Western blot and RT-qPCR, respectively. The results demonstrated that following BXD intervention, the proliferation of HT29 and HCT116 cells was significantly reduced. Furthermore, BXD promoted the apoptosis, enhanced the expression of Bcl-2, and suppressed the expression of Bax in colon cancer cells. At the same time, BXD suppressed the cell migration and invasion and augmented the expression of E-cadherin while diminishing the expression of N-cadherin and vimentin. In addition, BXD down-regulated the protein and mRNA levels of PARG, PARP1, and NF-κB p65. In conclusion, BXD may inhibit the malignant phenotypes of colon cancer cells by mediating the PARG/PARP1/NF-κB signaling pathway.

This study aims to explore the protective effect of Chaihu Jia Longgu Muli Decoction on rats with heart failure after myocardial infarction, and to clarify its possible mechanisms, providing a new basis for basic research on the mechanism of classic Chinese medicinal formula-mediated inflammatory response in preventing and treating heart failure induced by apoptosis after myocardial infarction. A heart failure model after myocardial infarction was established in rats by coronary artery ligation. The rats were divided into sham group, model group, and low, medium, and high-dose groups of Chaihu Jia Longgu Muli Decoction, with 10 rats in each group. The low-dose, medium-dose, and high-dose groups of Chaihu Jia Longgu Muli Decoction were given 6.3, 12.6, and 25.2 g·kg~(-1) doses by gavage, respectively. The sham group and model group were given an equal volume of distilled water by gavage once daily for four consecutive weeks. Cardiac function was assessed using color Doppler echocardiography. Myocardial pathology was detected by hematoxylin-eosin(HE) staining, apoptosis was measured by TUNEL assay, and mitophagy was observed by transmission electron microscopy. The levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-1β, and N-terminal pro-B-type natriuretic peptide(NT-proBNP) in serum were detected by enzyme-linked immunosorbent assay(ELISA). The expression of apoptosis-related proteins B-cell lymphoma 2(Bcl-2), Bcl-2-associated X protein(Bax), and cleaved caspase-3 was detected by Western blot. Additionally, the expression of phosphorylated nuclear transcription factor-κB(NF-κB) p65(p-NF-κB p65)(upstream) and nuclear factor kappa B inhibitor alpha(IκBα)(downstream) in the NF-κB signaling pathway was assessed by Western blot. The results showed that compared with the sham group, left ventricular ejection fraction(LVEF) and left ventricular short axis shortening(LVFS) in the model group were significantly reduced, while left ventricular end diastolic diameter(LVEDD) and left ventricular end systolic diameter(LVESD) increased significantly. Myocardial tissue damage was severe, with widened intercellular spaces and disorganized cell arrangement. The apoptosis rate was increased, and mitochondria were enlarged with increased vacuoles. Levels of TNF-α, IL-1β, and NT-proBNP were elevated, indicating an obvious inflammatory response. The expression of pro-apoptotic factors Bax and cleaved caspase-3 increased, while the anti-apoptotic factor Bcl-2 decreased. The expression of p-NF-κB p65 was upregulated, and the expression of IκBα was downregulated. In contrast, the Chaihu Jia Longgu Muli Decoction groups showed significantly improved of LVEF, LVFS and decreased LVEDD, LVESD compared to the model group. Myocardial tissue damage was alleviated, and intercellular spaces were reduced. The apoptosis rate decreased, mitochondrial volume decreased, and the levels of TNF-α, IL-1β, and NT-proBNP were lower. The expression of pro-apoptotic factors Bax and cleaved caspase-3 decreased, while the expression of the anti-apoptotic factor Bcl-2 increased. Additionally, the expression of p-NF-κB p65 decreased, while IκBα expression increased. In summary, this experimental study shows that Chaihu Jia Longgu Muli Decoction can reduce the inflammatory response and apoptosis rate in rats with heart failure after myocardial infarction, which may be related to the regulation of the IκBα/NF-κB signaling pathway.

Monosodium urate (MSU)-induced the gouty arthritis (GA) model was used to investigate the effect of Nod-like receptor protein 3 (NLRP3) inhibitor N14 in alleviating GA. Firstly, the effect of NLRP3 inhibitor N14 on the viability of mouse monocyte macrophage J774A.1 was examined by the cell counting kit-8 (CCK-8) assay. The expression of mature interleukin 1β (IL-1β) and cysteinyl aspartate specific proteinase-1 (caspase-1) p20 in the cell supernatant and the expression of NLRP3, caspase-1 and pro-IL-1β proteins in the cell lysates was detected by Western blot for the inhibitory effect of N14 on the MSU-induced NLRP3 inflammasome activation in J774A.1 cells. Animal behavioral tests were used to detect redness, swelling, heat and pain in mice with gouty arthritis. Hematoxylin-eosin (H&E) staining revealed pathologic changes and inflammatory infiltration in foot sections. Protein expression of NLRP3, caspase-1, and pro-IL-1β in mouse hind paw tissues were assessed by Western blot. The effect of N14 on the plasma levels of alanine transaminase (ALT), aspartate transaminase (AST), creatinine (CRE), urea, and uric acid (UA) was investigated by the MSU-induced gouty arthritis model in mice. All animal experiments in this paper were approved by the Scientific Ethics Review Board of Qingdao Marine Biomedical Research Institute (grant No. E-MBWNL-2024-20). The experimental results showed that N14 did not exhibit cytotoxicity in mouse monocyte macrophage J774A.1 cells at concentrations up to 100 μmol·L^-1, and N14 effectively prevented MSU-induced activation of NLRP3 inflammasome. In the mouse gouty arthritis model, N14 significantly ameliorated the redness, swelling, heat and pain caused by GA, and down-regulated the levels of NLRP3 inflammasome-associated proteins in mouse hind paw tissues. Meanwhile, N14 appeared to be well tolerated, as it did not significantly affect various biochemical indices in mouse plasma. In conclusion, N14 effectively alleviated GA in mice by inhibiting the NLRP3 inflammasome pathway, which is important for both prevention and treatment of related diseases.

Objective:To investigate the effects of ATG5 and ATG7 genes on the sensitivity of multiple myeloma(MM)cell line RPMI-8226 cells to ferroptosis.Methods:CRISPR/Cas9 technology was used to knock out the autophagy key genes ATG5 and ATG7 in RPMI-8226 cells.Western blot was used to identify gene knockout cells,and detect the expression changes of autophagy-related proteins P62 and LC3B.Flow cytometry was used to detect the change of sensitivity of gene knockout cells to RSL3.The content of intracellular ferrous ions and reactive oxygen species(ROS)level in gene knockout cells were detected.Results:Western blot result confirmed that ATG5 and ATG7 genes were knocked out successfully in RPMI-8226 cells.The result of flow cytometry showed that the cell viability of RPMI-8226 cells was dose-dependent on different concentrations of RSL3(r=-0.969).RSL3(10 μmol/L)was used to induce ferroptosis in cells of control group and gene knockout groups,then the cell viability in gene knockout groups were both higher than control group after 48 hours(both P＜0.001).After knocking out the ATG5 and ATG7 genes,the content of intracellular Fe2+decreased significantly compared with control group(both P＜0.01),and the ROS level also decreased(both P＜0.001).Conclusion:Knockout of ATG5 and ATG7 genes can inhibit the ferroptosis of MM cells,and LAP pathway may be involved in the regulation.

Objective:To explore the efficacy of adjuvant chemotherapy and adjuvant immunotherapy combined chemotherapy after radical cystectomy for muscle-invasive bladder cancer (MIBC) with high recurrence risk (pT 2 with positive lymph nodes, and pT 3-4a with or without positive lymph nodes). Methods:A retrospective analysis was conducted on clinical data of 217 patients with bladder cancer admitted to Tianjin Medical University Second Hospital from August 2016 to January 2022. Among them, 183 were male (84.3%) and 34 were female (15.7%), with an average age of (67.3±8.6) years old. All 217 patients underwent radical cystectomy with pelvic lymph node dissection. Based on postoperative adjuvant treatment, the patients were divided into an observation group (147 cases, 67.7%) and a treatment group (70 cases, 32.3%). The observation group and treatment group had similar demographic and pathological characteristics. The age of the observation group and treatment group was (67.4±9.0) years and (66.3±7.6) years, respectively ( P=0.14). The postoperative pathological stages T 2 with lymph node positivity were observed in 8 cases (5.4%) in the observation group and 6 cases (8.6%) in the treatment group. For stages T 3-4awith lymph node positivity, there were 34 cases (23.1%) in the observation group and 18 cases (25.7%) in the treatment group. And there were 105 cases (71.5%) in the observation group and 46 cases (65.7%) in the treatment group of stages T 3-4a without lymph node positivity, respectively( P>0.05). Tumor diameter ≥3 cm was found in 118 cases (80.3%) in the observation group and 54 cases (77.1%) in the treatment group ( P>0.05), while tumor diameter <3 cm was observed in 29 cases (19.7%) in the observation group and 16 cases (22.9%) in the treatment group ( P>0.05).In the treatment group, 36 patients (16.6%) received postoperative chemotherapy with gemcitabine (1 000 mg/m 2, days 1 and 8) and cisplatin (75 mg/m 2, days 2 to 4) (chemotherapy group), while 34 patients (15.7%) received postoperative immunotherapy with checkpoint inhibitors (intravenous infusion of sintilimab 200 mg, terlizumab 200 mg, or toripalimab 240 mg on day 1) in combination with albumin-bound paclitaxel (200 mg on day 2)(immunotherapy combined chemotherapy group). The age of the chemotherapy group and immunotherapy combined chemotherapy group was (66.8±8.4) years and (65.8±6.8) years, respectively ( P>0.05). Postoperative pathological stages T 2 with lymph node positivity were observed in 3 cases (8.3%) in the chemotherapy group and 3 cases (8.8%) in the immunotherapy combined chemotherapy group ( P>0.05). For stages T 3-4awith lymph node positivity, there were 6 cases (16.7%) in the chemotherapy group and 12 cases (35.3%) in the immunotherapy combined chemotherapy group. And there were 27 cases (75.0%) in the observation group and 19 cases (55.9%) in the treatment group of stages T 3-4a without lymph node positivity, respectively( P>0.05). Lymph node involvement was seen in 9 cases (25.0%) in the chemotherapy group and 15 cases (44.1%) in the immunotherapy combined chemotherapy group ( P>0.05). Tumor diameter ≥3 cm was found in 30 cases (83.3%) in the chemotherapy group and 10 cases (29.4%) in the immunotherapy combined chemotherapy group ( P>0.05), while tumor diameter <3 cm was observed in 6 cases (16.7%) in the chemotherapy group and 24 cases (70.6%) in the immunotherapy combined chemotherapy group ( P>0.05). Kaplan-Meier method and multivariate Cox regression test were used to analyze the overall survival (OS) at 1 and 3 years in the observation group and treatment group, as well as the disease-free survival (DFS) at 1 and 3 years in the chemotherapy group and immunotherapy combined chemotherapy group. Additionally, common adverse events were evaluated and compared between the chemotherapy group and immunotherapy combined chemotherapy group based on the criteria published by the U. S. Department of Health and Human Services. Results:The median follow-up time in this study was 18.4 (8.2, 34.7) months. The median follow-up time in the observation group and treatment group was 19.0 (8.3, 35.2) months and 17.5 (7.9, 33.2) months, respectively. The 1-year survival rate was significantly higher in the treatment group compared to the observation group (90.0% vs. 76.2%, χ2=6.92, P=0.009). Similarly, the 3-year survival rate was significantly higher in the treatment group compared to the observation group (82.9% vs. 57.8%, χ2=13.22, P<0.01). The median OS was 35.9 months in the observation group and was not reached in the treatment group, with a statistically significant difference ( HR=2.51, 95% CI 1.36-4.65, P=0.003).In the chemotherapy group and immunotherapy combined chemotherapy group, the median follow-up time was 10.7 (7.4, 22.1) months and 14.4 (6.3, 40.7) months, respectively. The 1-year disease-free survival rate was significantly higher in the immunotherapy combined chemotherapy group compared to the chemotherapy group (91.2% vs. 67.6%, χ2=4.60, P=0.032). The 3-year disease-free survival rate was significantly higher in the chemotherapy group compared to the immunotherapy combined chemotherapy group (88.2% vs. 55.6%, χ2=8.37, P=0.004). The median DFS was 27.7 months in the chemotherapy group and was not reached in the immunotherapy combined chemotherapy group, with a statistically significant difference ( HR=3.39, 95% CI 1.46-7.89, P=0.016).The treatment group had complications classified as follows: 140 cases of grade 1, 39 cases of grade 2, 8 cases of grade 3, 2 cases of grade 4, and 0 case of grade 5 adverse reactions. In the chemotherapy group and the immunotherapy combined chemotherapy group, there were both 5 cases with adverse reactions of grade 3 or higher. Specifically, in the chemotherapy group, there were 2 cases of anemia, 2 cases of decreased platelet count, and 1 case of decreased neutrophil count. In the immunotherapy combined chemotherapy group, there was 1 case of anemia, 1 case of decreased platelet count, and 2 cases of decreased neutrophil count. Additionally, there was 1 case with elevated gamma-glutamyltransferase (γ-GT) in the immunotherapy combined chemotherapy group. The incidence of adverse events of grade 3 or higher in the chemotherapy group and immunotherapy combined chemotherapy group was 13.9% and 14.7%, respectively, with no statistically significant difference( χ2=0.01, P=0.922). Conclusions:Adjuvant therapy significantly prolongs the overall survival in high risk of recurrence for MIBC patients after radical cystectomy. For patients intolerant to platinum-based chemotherapy or refusing platinum-based adjuvant chemotherapy, immunotherapy with checkpoint inhibitors combined with albumin-bound paclitaxel can be considered as an effective and well-tolerated adjuvant treatment after radical cystectomy.

OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

OBJECTIVE: To study the prognostic value of LPCAT1 in acute myeloid leukemia (AML). METHODS: TaqMan-based reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to detect relative expression of LPCAT1 in 214 newly diagnosed adult AML patients and 24 normal controls. Survival functions were estimated using the Kaplan-Meier method and were compared by the Log-rank test. A Cox proportional hazard regression model was used to identify prognostic factors. RESULTS: The expression level of LPCAT1 in adult AML was 34.37%(1.83%-392.63%), which was significantly lower than 92.81%(2.60%-325.84%) of normal controls (P<0.001). The prognostic significance of LPCAT1 was evaluated in 171 non-acute promyelocytic leukemia patients with complete clinical information and prognostic data. Survival analysis showed that the expression level of LPCAT1 had no significant effect on the prognosis of the whole cohort. However, in AML patients with FAB subtype M2 (AML-M2), the 2-year relapse-free survival (RFS) rate of patients with low LPCAT1 expression was 35.4%(95%CI: 0.107-0.601), which was significantly lower than 79.2%(95%CI: 0.627-0.957) of patients with high LPCAT1 expression (P=0.012). Multivariate analysis showed that low expression of LPCAT1 was an independent risk factor for RFS of AML-M2 patients (HR=0.355, 95%CI: 0.126-0.966, P=0.049). CONCLUSION In adult AML patients LPCAT1 shows low expression. Low LPCAT1 expression is an independent risk factor for RFS in M2-AML patients.

To understand the current quality status and rearing situation of Bombyx Batryticatus, the authors collected 102 batches of Bombyx Batryticatus from different main producing areas and five major Chinese medicine markets from 2016 to 2018, and measured the properties and quality of the silk gland, to clarify the quality status of Bombyx Batryticatus from different producing areas and markets. In addition, 35 batches of Bombyx Batryticatus from 2019 to 2022 were used to verify the silk gland after revision. Moreover, Beauveria Bassiana was inoculated in the silkworm of 4-5 instars, and standardized rearing was carried out until they die. The death rate and the quality of Bombyx Batryticatus were measured to determine the differences in Bombyx Batryticatus of different instars, and explore the rationality of the infection age of Bombyx Batryticatus in Chinese Pharmacopoeia(2020). The results revealed that in the 102 batches of Bombyx Batryticatus, the qualification rate of silk gland was low; the content of total ash far exceeded the standard; the content of beauvericin varied greatly. The qualification rate of the silk gland of the 35 batches of Bombyx Batryticatus was only 47.49%, which could be increased to 73.00% if the number of silk gland was 2 to 4. The death rate of Bombyx Batryticatus at different infection ages was quite different, with uneven quality. Generally, the yield of Bombyx Batryticatus inoculated on the first day of the fifth instar was high with good quality. Therefore, in combination with the quality and actual production of Bombyx Batryticatus, the following suggestions were proposed for revision of Bombyx Batryticatus in Chinese Pharmacopoeia(2025): The number of silk gland should be revised as 2-4 bright brown or bright black silk glands, after which, the quality of Bombyx Batryticatus could be guaranteed, and the "quality identification based on character" could also be reflected scientifically; the content determination index that the content of beauvericin shall not be less than 0.017% should be added to better control the quality of Bombyx Batryticatus; the infection age should be revised as the first day of the fifth instar to narrow the age span, which could better fit the actual production and ensure the quality of Bombyx Batryticatus.
