ObjectiveTo study the mechanism of compound Xishu granules (CXG) in inhibiting the proliferation of hepatocellular carcinoma cells by regulating ferroptosis. MethodsThe transplanted tumor model of human Huh7 was established with nude mice and the successfully modeled mice were randomized into model, Fufang Banmao (0.21 g·kg-1), low-dose (1.87 g·kg-1) CXG, medium-dose (3.74 g·kg-1) CXG, and high-dose (7.49 g·kg-1) CXG groups. Mice were administrated with drinking water or CXG for 28 days, and the body weight and tumor volume were measured every 4 days. Hematoxylin-eosin staining was employed to observe the histopathological changes of tumors. The cell-counting kit-8 (CCK-8) was used to examine the survival rate of Huh7 cells treated with different concentrations (0, 31.25, 62.5, 125, 250, 500, 1 000 mg·L-1) of CXG for 24 h and 48 h. CA-AM, DCFH-DA, and C11-BODIPY581/591 fluorescent probes were used to determine the intracellular levels of ferrous ion (Fe2+), reactive oxygen species (ROS), and lipid peroxide (LPO), respectively. The colorimetric method was employed to measure the levels of glutathione (GSH) and superoxide dismutase (SOD). Western blot was employed to determine the protein levels of glutathione peroxidase 4 (GPX4), transferrin receptor 1 (TFR1), and ferritin heavy chain 1 (FTH1), respectively. ResultsIn the animal experiment, compared with the model group, the drug treatment groups showed reductions in the tumor volume from day 12 (P<0.01). After treatment, the Fufang Banmao and low-, medium-, and high-dose CXG groups had lower tumor volume, relative tumor volume, and tumor weight than the model group (P<0.05), with tumor inhibition rates of 48.99%, 79.93%, 91.38%, and 97.36%, respectively. Moreover, the CXG groups had lower tumor volume and relative tumor volume (P<0.05 in all the three dose groups) and lower tumor weight (P<0.05 in medium-dose and high-dose groups) than the Fufang Banmao group. Compared with the model group, the drug treatment groups showed reduced number of tumor cells, necrotic foci with karyopyknosis, nuclear fragmentation, and nucleolysis, and the high-dose CXG group showed an increase in the proportion of interstitial fibroblasts. In the cell experiment, compared with the blank group, CXG reduced the survival rate of Huh7 cells in a dose-dependent manner after incubation for 24 h and 48 h (P<0.05). Compared with the blank group, the RSL3 group and the low-, medium-, and high-dose CXG groups showed a decrease in the relative fluorescence intensity of CA-AM and increases in the fluorescence intensity of DCFH-DA and fluorescence ratio of C11-BODIPY581/591, which indicated elevations in the levels of Fe2+ (P<0.01), ROS (P<0.05), and LPO (P<0.01), respectively. Compared with the blank group, the RSL3 and low-, medium-, and high-dose CXG groups showed lowered levels of GSH and SOD (P<0.05). In addition, the RSL3 group and the medium- and high-dose CXG groups showed down-regulated expression of GPX4 and FTH1 (P<0.05), and the low- and high-dose CXG groups presented up-regulated expression of TFR1 (P<0.05). ConclusionCXG suppresses the proliferation of hepatocellular carcinoma cells by inducing ferroptosis via downregulating the GSH-GPX4 signaling axis and increasing intracellular Fe2+and LPO levels.

Tumor drug resistance is an important problem in the failure of chemotherapy and targeted drug therapy, which is a complex process involving chromatin remodeling. SWI/SNF is one of the most studied ATP-dependent chromatin remodeling complexes in tumorigenesis, which plays an important role in the coordination of chromatin structural stability, gene expression, and post-translation modification. However, its mechanism in tumor drug resistance has not been systematically combed. SWI/SNF can be divided into 3 types according to its subunit composition: BAF, PBAF, and ncBAF. These 3 subtypes all contain two mutually exclusive ATPase catalytic subunits (SMARCA2 or SMARCA4), core subunits (SMARCC1 and SMARCD1), and regulatory subunits (ARID1A, PBRM1, and ACTB, etc.), which can control gene expression by regulating chromatin structure. The change of SWI/SNF complex subunits is one of the important factors of tumor drug resistance and progress. SMARCA4 and ARID1A are the most widely studied subunits in tumor drug resistance. Low expression of SMARCA4 can lead to the deletion of the transcription inhibitor of the BCL2L1 gene in mantle cell lymphoma, which will result in transcription up-regulation and significant resistance to the combination therapy of ibrutinib and venetoclax. Low expression of SMARCA4 and high expression of SMARCA2 can activate the FGFR1-pERK1/2 signaling pathway in ovarian high-grade serous carcinoma cells, which induces the overexpression of anti-apoptosis gene BCL2 and results in carboplatin resistance. SMARCA4 deletion can up-regulate epithelial-mesenchymal transition (EMT) by activating YAP1 gene expression in triple-negative breast cancer. It can also reduce the expression of Ca2+ channel IP3R3 in ovarian and lung cancer, resulting in the transfer of Ca2+ needed to induce apoptosis from endoplasmic reticulum to mitochondria damage. Thus, these two tumors are resistant to cisplatin. It has been found that verteporfin can overcome the drug resistance induced by SMARCA4 deletion. However, this inhibitor has not been applied in clinical practice. Therefore, it is a promising research direction to develop SWI/SNF ATPase targeted drugs with high oral bioavailability to treat patients with tumor resistance induced by low expression or deletion of SMARCA4. ARID1A deletion can activate the expression of ANXA1 protein in HER2+ breast cancer cells or down-regulate the expression of progesterone receptor B protein in endometrial cancer cells. The drug resistance of these two tumor cells to trastuzumab or progesterone is induced by activating AKT pathway. ARID1A deletion in ovarian cancer can increase the expression of MRP2 protein and make it resistant to carboplatin and paclitaxel. ARID1A deletion also can up-regulate the phosphorylation levels of EGFR, ErbB2, and RAF1 oncogene proteins.The ErbB and VEGF pathway are activated and EMT is increased. As a result, lung adenocarcinoma is resistant to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). Although great progress has been made in the research on the mechanism of SWI/SNF complex inducing tumor drug resistance, most of the research is still at the protein level. It is necessary to comprehensively and deeply explore the detailed mechanism of drug resistance from gene, transcription, protein, and metabolite levels by using multi-omics techniques, which can provide sufficient theoretical basis for the diagnosis and treatment of poor tumor prognosis caused by mutation or abnormal expression of SWI/SNF subunits in clinical practice.

ObjectiveTo evaluate the efficacy of Shuanghua drink in treating primary dysmenorrhea in the rat model and explore its mechanism of action. MethodsAn oxytocin-induced writhing mouse model was established to evaluate the analgesic effect of Shuanghua drink. Forty-eight non-pregnant female institute of cancer research (ICR) mice were randomly divided into six groups, including a blank group, a model group, an ibuprofen group (85.00 mg·kg-1), a low-dose group of Shuanghua drink (7.14 mL·kg-1), a medium-dose group of Shuanghua drink (14.28 mL·kg-1), and a high-dose group of Shuanghua drink (28.57 mL·kg-1). Each group consisted of eight mice. All treatment groups received daily intragastric administration at corresponding doses for 10 consecutive days. One hour after the final administration, 2 U of oxytocin was intraperitoneally injected per mouse. The writhing latency and number of writhing within 20 minutes were recorded. A primary dysmenorrhea rat model was established by using estradiol benzoate and oxytocin to evaluate the inhibitory effect of Shuanghua drink on the contraction of uterine smooth muscle. Forty-eight non-pregnant female Sprague-Dawley (SD) rats were divided into six groups, including a blank group, a model group, an ibuprofen group (51.00 mg·kg-1), a low-dose group of Shuanghua drink (4.28 mL·kg-1), a medium-dose group of Shuanghua drink (8.57 mL·kg-1), and a high-dose group of Shuanghua drink (17.10 mL·kg-1). Each group consisted of eight rats. Rats received subcutaneous injections of estradiol benzoate for 10 consecutive days to enhance uterine sensitivity. On the eleventh day, oxytocin (2 U/rat) was intraperitoneally administered to induce abnormal uterine contractions for establishing the primary dysmenorrhea model. All treatment groups received daily intragastric administration from the second day of modeling for 10 days. The effects of Shuanghua drink were evaluated by using parameters including uterine motility and the variation rate of uterine motility. The mechanism of action was investigated in rats with primary dysmenorrhea. The content of prostaglandin F2α (PGF2α), prostaglandin E2 (PGE2), thromboxane B2 (TXB2), prostacyclin metabolite (6-keto-PGF1α), and β-endorphin (β-EP) in uterine tissue of rats was detected by using enzyme-linked immunosorbent assay (ELISA). The changes in the content of nitric oxide (NO) and inducible nitric oxide synthase (iNOS) were analyzed via colorimetric assay. Western blot was performed to determine the content of phosphorylated inhibitor of kappa B kinase beta (p-IKKβ)/IKKβ, phosphorylated inhibitor of kappa B alpha (p-IκBα), IκBα, phosphorylated p65 (p-p65), p65, and cyclooxygenase-2 (COX-2) proteins in uterine tissue of rats. ResultsIn the oxytocin-induced writhing mouse model, the model group exhibited significantly shortened writhing latency and increased writhing frequency compared to the control group (P<0.01). Both the ibuprofen group and the high-dose group of Shuanghua drink displayed prolonged writhing latency (P<0.05), while the ibuprofen group and the low-dose, medium-dose, and high-dose groups of Shuanghua drink exhibited reduced writhing frequency (P<0.01). In the primary dysmenorrhea rat model, the uterine motility and its variation rate in the model group were significantly higher than those in the blank group (P<0.01). These parameters were markedly suppressed by ibuprofen and Shuanghua drink at all tested doses (P<0.01). For the mechanism of action, the model group showed significantly increased PGF2α/PGE2, TXB2/6-keto-PGF1α, NO, and iNOS in uterine tissue (P<0.05, P<0.01) and significantly decreased β-EP (P<0.01). These parameters were significantly attenuated in the ibuprofen group and the low-dose, medium-dose, and high-dose groups of Shuanghua drink. The PGF2α/PGE2 (P<0.01), TXB2/6-keto-PGF1α (P<0.01), NO (medium-dose group P<0.05), and iNOS (P<0.01) were reduced, and the β-EP (medium-dose group P<0.05) was up-regulated. Compared to the model group, the ibuprofen group and medium-dose group of Shuanghua drink showed significantly increased content of β-EP in the serum of rats (P<0.05). Compared to the blank group, the model group showed significantly elevated expressions of COX-2, p-IKKβ/IKKβ, p-IκBα/IκBα, and p-p65/p65 proteins (P<0.01) and significantly reduced anti-inflammatory protein IκBα (P<0.05). Compared to the model group, the ibuprofen group and the low-dose, medium-dose, and high-dose groups of Shuanghua drink showed significantly reduced expressions of COX-2 (P<0.01), p-IKKβ/IKKβ (P<0.01), p-IκBα/IκBα (P<0.05, P<0.01), and p-p65/p65(P<0.01) and up-regulated expression of IκBα protein (P<0.05, P<0.01). ConclusionShuanghua drink effectively alleviates primary dysmenorrhea through analgesia and suppression of abnormal contractions of uterine smooth muscle. Its mechanism may be mediated by reduced levels of PGF2α/PGE2, TXB2/6-keto-PGF1α, iNOS, and NO, elevated β-EP level, and inhibited COX-2/NF-κB signaling pathway.

Intelligence encompasses various abilities, including logical reasoning, comprehension, self-awareness, learning, planning, creativity, and problem-solving. Extensive research and practical experience suggest that there are sex differences in intellectual development, with females typically maturing earlier than males. However, the key genes and molecular network mechanisms underlying these sex differences in intellectual development remain unclear. To date, Genome-Wide Association Studies (GWAS) have identified 507 genes that are significantly associated with intelligence. This study first analyzed RNA sequencing data from different stages of brain development (from BrainSpan), revealing that during the late embryonic stage, the average expression levels of intelligence-related genes are higher in males than in females, while the opposite is observed during puberty. This study further constructed interaction networks of intelligence-related genes with sex-differential expression in the brain, including the prenatal male network (HELP-M: intelligence genes with higher expression levels in prenatal males) and the pubertal female network (HELP-F: intelligence genes with higher expression levels in pubertal females). The findings indicate that the key genes in both networks are Ep300 and Ctnnb1. Specifically, Ep300 regulates the transcription of 53 genes in both HELP-M and HELP-F, while Ctnnb1 regulates the transcription of 45 genes. Ctnnb1 plays a more prominent role in HELP-M, while Ep300 is more crucial in HELP-F. Finally, this study conducted sequencing validation on rats at different developmental stages, and the results indicated that in the prefrontal cortex of female rats during adolescence, the expression levels of the intelligence genes in HELP-F, as well as key genes Ep300 and Ctnnb1, were higher than those in male rats. These genes were also involved in neurodevelopment-related biological processes. The findings reveal a sex-differentiated intelligence gene network and its key genes, which exhibit varying expression levels during the neurodevelopmental process.

The efficacy and safety of different Chinese patent medicines in the treatment of stable chronic obstructive pulmonary disease(COPD) were evaluated by network Meta-analysis. The randomized controlled trial(RCT) of Chinese patent medicines for stable COPD were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, Web of Science, EMbase, and Cochrane Library with the time interval from inception to February 2024. The quality of the included RCT was evaluated by the Cochrane's risk of bias assessment tool. RevMan 5.4 and Stata 16.0 were used to establish the risk of bias diagram and perform the network Meta-analysis. A total of 113 RCTs were included, involving 8 265 patients and 14 Chinese patent medicines. The network Meta-analysis yielded the following results based on the surface under the cumulative ranking curve(SUCRA).(1) In terms of improving the forced expiratory volume in 1 second to forced vital capacity(FEV1/FVC) ratio, the top three treatments were Jingshuibao Capsules + conventional western medicine, Yupingfeng San + conventional western medicine, and Sanzi Zhike Capsules + conventional western medicine.(2) In terms of improving the clinical efficacy, the top three treatments were Yifei Capsules + conventional western medicine, Yupingfeng Granules + conventional western medicine, and Bufei Huoxue Capsules + conventional western medicine.(3) In terms of improving the percentage of predicted FEV1(FEV1%pred), the top three treatments were Jingshuibao Capsules + conventional western medicine, Bufei Granules + conventional western medicine, and Bailing Capsules + conventional western medicine.(4) In terms of improving the distance in 6 min walking test(6MWT), the top three treatments were Jingshuibao Capsules + conventional western medicine, Bailing Capsules + conventional western medicine, and Jianpi Yifei Oral Liquid + conventional western medicine.(5) In terms of reducing the COPD assessment test(CAT), the top three treatments were Bufei Granules + conventional western medicine, Yifei Capsules + conventional western medicine, and Yifei Huoxue Granules + conventional western medicine.(6) In terms of reducing the frequency of acute exacerbation of chronic obstructive pulmonary disease(AECOPD) within 1 year, the top three treatments were Yupingfeng Capsules + conventional western medicine, Yupingfeng San + conventional western medicine, and Jianpi Yifei Oral Liquid + conventional western medicine.(7) In terms of safety, 28 RCTs have reported adverse reactions, mainly involving the digestive system, circulatory system, and nervous system. The results showed that Chinese patent medicines combined with conventional western medicine improved FEV1/FVC, FEV1%pred, clinical efficacy, and 6MWT, while reducing CAT and the frequency of AECOPD within 1 year. However, due to the limitations of the included studies and the lack of direct comparisons between different interventions, these results need further validation.

OBJECTIVES:
To investigate the dynamic changes in serum microRNA-15b (miR-15b) and vascular endothelial growth factor (VEGF) in preterm infants with mild or moderate-to-severe bronchopulmonary dysplasia (BPD), as well as their value in assessing short-term neurodevelopment.
METHODS:
A retrospective analysis was conducted on the medical data of 156 preterm infants with BPD who were admitted to the neonatal intensive care unit from January 2020 to February 2023. According to the severity of BPD, they were divided into a mild group (n=88) and a moderate-to-severe group (n=68). Serum levels of miR-15b and VEGF were measured on postnatal days 1, 7, 14, and 28. Repeated measures analysis of variance was used to assess the dynamic changes in serum levels of miR-15b and VEGF. The mediating effect of VEGF between miR-15b and short-term neurological development was tested and analyzed using the stepwise regression method and the Bootstrap method. Logistic regression analysis was used to identify factors influencing adverse neurodevelopmental outcomes.
RESULTS:
In the mild group, there was a significant reduction in the serum level of miR-15b and a significant increase in VEGF over time (P<0.05), while in the moderate-to-severe group, there was a significant increase in miR-15b and a significant reduction in VEGF over time (P<0.05). Serum miR-15b and VEGF levels were important factors influencing neurodevelopmental outcomes, showing independent correlations (P<0.001). The mediating effect analysis indicated that miR-15b indirectly affected short-term neurodevelopment by inhibiting VEGF expression [indirect effect: -0.705 (95%CI: -1.178 to -0.372)], with the indirect effect accounting for 54.36% of the total effect.
CONCLUSIONS
There are different changing trends in serum levels of miR-15b and VEGF in preterm infants with mild and moderate-to-severe BPD. miR-15b primarily influences neurodevelopment through VEGF.

OBJECTIVE:
To investigate the predictive value of endothelial activation and stress index (EASIX) for the prognosis of patients with mantle cell lymphoma (MCL).
METHODS:
A retrospective analysis was conducted to assess prognosis and compare the clinical features of patients diagnosed with MCL who were admitted to the Affiliated Hospital of Xuzhou Medical University from January 2010 to June 2023, had therapeutic indications and received standard treatment.
RESULTS:
A total of 66 patients were included and divided into high EASIX group and low EASIX group, according to a cutoff value of 0.97 determined by the receiver operating characteristic (ROC) curve. Multivariate Cox regression analysis showed that prealbumin <0.2 g/L, high EASIX, and ECOG PS score ≥2 were independent risk factors influencing overall survival (OS) in MCL patients. The median OS of patients in the high and low EASIX group was 13.0 and 37.5 months, and the median progression-free survival was 8.8 and 26.0 months, respectively. The proportions of patients with ECOG PS score ≥2 and prealbumin <0.2 g/L at onset significantly increased in the high EASIX group compared to those in the low EASIX group.
CONCLUSION
At the time of initial diagnosis, EASIX can serve as an independent prognostic indicator impacting OS in patients with MCL. Furthermore, patients in the high EASIX group experience a poorer prognosis and shorter survival duration compared with those in the low EASIX group.

OBJECTIVE:
To analyze the effect of altitude on NIH-CPSI score in patients with chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS) Methods: Clinical data and the results of NIH-CPSI Questionnaire of the 321 patients with CP/CPPS at different altitudes were collected from March 2021 to March 2022. And the influence of altitudes on NIH-CPSI score of CP/CPPS was analyzed.
RESULT:
The NIH-CPSI score of patients living at an altitude of 4 300 m was significantly higher than that of patients living at an altitude of 1 500 m and 2 200 m. The CP/CPPS patients who lived in the higher altitude had more severe symptoms of pain and urination as well as lower scores of life quality (P<0.05).
CONCLUSION
NIH-CPSI score increased significantly with higher altitude, indicating more severe symptoms and decreased quality of life in CP/CPPS patients. These findings highlight the need for management strategies for specific heights in patients with CP/CPPS.
