ObjectiveTo study the therapeutic mechanism of Xihuang Wan for hyperplasia of mammary glands based on network pharmacology， molecular docking， and cell experiments. MethodsThe active ingredients and targets of Xihuang Wan were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and A Bioinformatics Annotation daTabase for Molecular mechANism of Traditional Chinese Medicine （BATMAN-TCM） and supplemented by searching against PubChem and Swiss Target Prediction. The targets of differential metabolites in tissues and urine were obtained from previous metabolomics studies through PubChem and Swiss Target Prediction. GeneCards， Online Mendelian Inheritance in Man （OMIM）， PharmGKB， Therapeutic Target Database （TTD）， Drunbank were searched for the targets of hyperplasia of mammary glands. After the common targets were obtained via Veeny2.1.0， the STRING database was used to analyze the protein-protein interactions， and Cytoscape was used for the core target analysis and visualization. Gene Ontology （GO） and the Kyoto Encyclopedia of Genes and Genomes （KEGG） were employed for enrichment analysis. Molecular docking was carried out in Autodock， and cell experiments were conducted to verify the prediction results. In the cell experiments， estradiol and progesterone （E₂+P） were used to intervene in human mammary epithelial/MCF-10A cells， and thus the MCF-10A cell proliferation model was established. The cells were then treated with Xihuang Wan-medicated serum. The cell counting kit-8 （CCK-8） was used to measure the cell proliferation， and flow cytometry was used to detect apoptosis. The mRNA and protein levels of key factors in MCF-10A cells were determined by real-time PCR and Western blot， respectively. ResultsThe results of network pharmacology showed that 90 active ingredients and 316 common targets were obtained， from which 20 core targets and 38 corresponding active ingredients were screened out. The results of GO and KEGG enrichment analyses showed that Xihuang Wan exerted effect against hyperplasia of mammary glands by regulating a variety of biological processes， which may be related to protein kinase B （Akt）-related molecular functions， estrogen signaling pathway， prolactin signaling pathway and other biological processes. The results of molecular docking showed that estrogen receptor 1 （ESR1）， serine/threonine kinase 1 （Akt1）， non-receptor tyrosine kinase （SRC）， and signal transducer and activator of transcription 3 （STAT3） all had strong binding activity with the nine active ingredients， suggesting that Xihuang Wan exert the effect through the ESR1/SRC/phosphatidylinositol 3-kinase （PI3K）/Akt signaling pathway and the Janus kinase （JAK）/STAT3 signaling pathway. The results of cell experiments showed that E₂+P intervention in MCF-10A cells promoted the proliferation of MCF-10A cells （P<0.05）， while the Xihuang Wan-medicated serum inhibited the proliferation of MCF-10A cells exposed to E₂+P （P<0.05）. Flow cytometry showed that the Xihuang Wan-medicated serum promoted the apoptosis of MCF-10A cells exposed to E₂+P （P<0.01）. The results of Real-time PCR showed that the Xihuang Wan-medicated serum down-regulated the mRNA levels of PI3K， Akt， JAK2， and STAT3 in MCF-10A cells treated with E₂+P （P<0.01）. The results of Western blot showed that the Xihuang Wan-medicated serum inhibited the expression of p-PI3K/PI3K， p-Akt/Akt， p-JAK2/JAK2， and p-STAT3/STAT3 in MCF-10A cells treated with E₂+P （P<0.05）. ConclusionXihuang Wan may exert the effect against hyperplasia of mammary glands by inhibiting the proliferation and promoting the apoptosis of MCF-10A cells， which may related to the inhibition of the activation of PI3K/Akt and JAK2/STAT3 signaling pathways.

Objective:To compare minimally invasive surgery with traditional open surgery, analyze the current application status of health economic evaluations in the treatment of digestive tract cancers, such as esophageal cancer, gastric cancer, and colorectal cancer by minimally invasive surgery and provide evidence for the rational selection of clinical treatment, alleviation of disease-related economic burdens, and rational allocation of healthcare resources.Methods:By using five databases, i.e. China National Knowledge Infrastructure, Wanfang data, Chinese Biomedical Literature Database, PubMed, and Embase, a database was established to retrieve all the papers about health economic studies of minimally invasive surgery for esophageal cancer, gastric cancer, and colorectal cancer published until December 31, 2023. Literature was analyzed by using software NoteExpress 3.8, and data were processed using Excel 2021. The quality of included papers was evaluated using the CHEERS 2022 checklist, and Meta-analysis was conducted by using software Stata 17.0.Results:A total of 10 919 relevant papers were retrieved, and 59 studies were included. Only 14 studies (23.7%) used standard health economic evaluation methods. Meta-analysis results revealed no significant differences in direct medical expenditure and total expenditure between minimally invasive surgery and open surgery. However, the expenditure for minimally invasive surgery exhibited a significant increase [mean difference ( MD)=5 973.12 yuan, P<0.001], while hospital stay and indirect expenditure significantly decreased ( MD: -4.85 days and -733.79 yuan, P<0.001). In China, for gastric cancer, the direct medical expenditure of endoscopic surgery was lower than that of open surgery ( MD=-33 000.00 yuan) with no significant difference ( P<0.001). In colorectal cancer cases, the direct medical and surgical expenditures for laparoscopic surgery were higher than those for open surgery ( MD: 4 277.94 yuan and 4 267.80 yuan, P<0.001), while the indirect and total medical expenditures decreased ( MD: -768.34 yuan and -159.10 yuan). Hospital stays in patients who had minimally invasive surgery for all three types of cancer were shorter than those who had open surgery ( P<0.001). Conclusions:In the treatment of gastrointestinal cancer, compared with open surgery, minimally invasive surgery shows higher expenditure, but has advantages, such as shorter hospital stay and lower indirect expenditure, and there were no significant differences in direct medical and total expenditures between the two approaches. When conducting health economic evaluation, factors such as postoperative complications, hospital stay, and patient's economic status should be considered for their impact on total medical expenditure. It is necessary to pay attention to the application of health economic evaluations in healthcare decision-making.

Xihuang pills are a classic Chinese patent medicine following the theoretical principle of combining eliminating pathogen with reinforcing healthy qi in both local areas and the whole body， with the effects of clearing heat， detoxifying， alleviating edema， and dissipating mass. This medicine is traditionally used for treating carbuncle， furuncle， multiple abscess， carcinoma of breast， phlegm nodule， scrofula， lung abscess， and intestine abscess caused by fire depression， phlegm stasis， and heat toxin stagnation. It is used for treating malignant tumors， breast hyperplasia， herpes zoster， lymphadenitis， pelvic inflammatory disease， mastitis， vocal cord leukoplakia， and acne in modern medicine. Xihuang pills are now included in the 2020 edition of the Chinese Pharmacopoeia. The use of high-quality medicinal materials and modern technology enables full retaining of the active components in the medicinal materials. The chemical components in this medicine mainly include amino acids， terpenoids， fatty acids， fatty acid esters， phenols， bile acids， bile pigments， and volatile oils. Modern pharmacological studies have shown that a variety of active components such as bilirubin， bile acid， boswellic acid， and volatile oil in Xihuang pills interact with each other to exert anti-tumor， anti-breast hyperplasia， immunomodulatory， anti-inflammatory， and neuroendocrine-regulating effect. This paper reviews the research progress in the active components and pharmacological effects of Xihuang pills and predicts the quality markers （Q-markers） of this medicine according to the transmission， traceability， specificity， efficacy， measurability， and compound compatibility in the concept of Q-marker. It is suggested that bilirubin， bile acid， taurine， muskone， 11-carbonyl-β-boswellic acid， β-boswellic acid， 3-acetyl-11-keto-β-boswellic acid， octyl acetate， β-elemene， and myrrhone can be used as Q-markers of Xihuang pills， which can provide a basis for research on the material basis and the quality control of Xihuang pills.

The pathogenesis of bipolar disorder(BD)is unknown,and objective biomarkers with clinical guidance are lacking.Extracellular vesicles(EV)are lipid bilayer-enclosed vesicles that carry cargo from originating cells,influencing the processes of recipient cells.They are capable of crossing the blood-brain barrier and reflecting the ongoing processes in the central nervous system.Compelling data indicates that EV could mediate BD pathophysiological processes such as neurocognitive impairment,neuroinflammatory diffusion,and metabolic dysfunction.Therefore,EV has the potential to become a reliable biomarker and therapy for BD,providing new ideas for revealing the pathogenesis and clinical diagnosis and treatment of BD.

BACKGROUND: Congenital heart disease (CHD) is one of the most common congenital malformations in humans. Inconsistent results emerged in the existed studies on associations between air pollution and congenital heart disease. The purpose of this study was to evaluate the association of gestational exposure to air pollutants with congenital heart disease, and to explore the critical exposure windows for congenital heart disease. METHODS: The nested case-control study collected birth records and the following health data in Tianjin Women and Children's Health Center, China. All of the cases of congenital heart disease from 2013 to 2015 were selected matching five healthy controls for each case. Inverse distance weighting was used to estimate individual exposure based on daily air pollution data. Furthermore, the conditional logistic regression with distributed lag non-linear model was performed to identify the association between gestational exposure to air pollution and congenital heart disease. RESULTS: A total of 8,748 mother-infant pairs were entered into the analysis, of which 1,458 infants suffered from congenital heart disease. For each 10 µg/m³ increase of gestational exposure to PM_2.5, the ORs (95% confidence interval, 95%CI) ranged from 1.008 (1.001-1.016) to 1.013 (1.001-1.024) during the 1^st-2^nd gestation weeks. Similar weak but increased risks of congenital heart disease were associated with O₃ exposure during the 1^st week and SO₂ exposure during 6^th-7^th weeks in the first trimester, while no significant findings for other air pollutants. CONCLUSIONS This study highlighted that gestational exposure to PM_2.5, O₃, and SO₂ had lag effects on congenital heart disease. Our results support potential benefits for pregnancy women to the mitigation of air pollution exposure in the early stage, especially when a critical exposure time window of air pollutants may precede heart development.

Objective:To evaluate percutaneous mechanical thrombectomy (PMT) using Aspirex device for treating acute iliofemoral deep vein thrombosis (IFDVT).Methods:The clinical and follow-up data of 68 patients with IFDVT at our institution from Jan 2019 to Jun 2021 was retrospectively analyzed.Results:Twenty-six patients who had received PMT combined with auxiliary catheter directed thrombolysis (CDT) were included into group A, and 42 patients received CDT alone were into group B.The final thrombus clearance rates were more than 50%, and the clinical efficacy of thrombolysis was achieved. Group A associated a significant reduction in lysis duration and UK dosage and hospital days and degree of detumescence after 24 h compared with group B,and all aforementioned differences were statistically significant. Hospitalization costs in group A were more than group B. At one year follow-up, there were no significant differences between the two groups in the cumulative prevalence post-thrombotic syndrome (PTS) and the Villalta score and primary patency (92.0% vs. 90.0% , χ2=0.059, P=0.807). Conclusions:The application of PMT using the Aspirex device for acute IFDVT was safe and effective, which could accelerate the clearance of thrombus, and reduce UK dosage, lysis duration, hospital days. However, it increased the hospitalization costs.

Objective:To observe the expression changes of microRNA(miR)-122 in liver tissue of rats infected with Clonorchis sinensis and its correlation with expression level of inflammatory cytokines. Methods:Totally 24 SPF grade Wistar male rats were selected and randomly divided into a control group (100 μl physiological saline gavage), a 4-week infection group (100 Clonorchis sinensis metacercariae gavage), and an 8-week infection group (100 Clonorchis sinensis metacercariae gavage) based on body weight (100-120 g) using a random number table method, with 8 rats in each group. Starting from the third week of infection, rat feces were collected and directly smeared with physiological saline for identification of Wistar rat animal models infected with Clonorchis sinensis. After 4 and 8 weeks of infection, the rats in the 4- and 8-week infection groups were euthanized, while 4 rats in the control group were euthanized, respectively. The heart blood and left lobe liver tissue and serum samples were collected from each group of rats. Using hematoxylin-eosin (HE) staining to observe liver pathological damage under the light microscope, real-time fluorescence quantitative PCR to detect the expression level of miR-122 in liver tissue, and Luminex 200 liquid suspension chip to detect the expression levels of serum inflammatory cytokines [tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), interleukin-6 (IL-6)]. The correlation between miR-122 and inflammatory cytokines was analyzed using Pearson correlation. Results:Under the light microscope, the morphology of hepatocytes in control group was normal, and no inflammatory cell infiltration was observed. There was inflammatory cells such as lymphocyte, eosinophil and other inflammatory cell infiltration around the portal area in the 4-week infection group. The hepatocytes of the 8-week infected rats were arranged in a disordered manner, with varying degrees of swelling, loose and lightly stained cytoplasm, and some hepatocytes showed watery degeneration; additionally, bile duct dilation and thickening of the bile duct wall were observed in the liver tissue. There were statistically significant differences of liver miR-122 (1.00 ± 0.32, 2.57 ± 0.60, 3.63 ± 1.63), serum TNF-α [(0.14 ± 0.06), (0.43 ± 0.09), (0.61 ± 0.10) ng/ml], and IL-6 expression levels [(0.03 ± 0.01), (1.06 ± 0.24), (1.48 ± 0.33) ng/ml] in control group, 4- and 8-week infection groups ( F = 13.36, 69.99, 82.23, P < 0.001). There was no statistically significant difference in expression level of IL-1β between different groups ( F = 2.15, P = 0.141). The Pearson correlation analysis showed that the expression level of miR-122 was positively correlated with the expression levels of inflammatory cytokines TNF-α and IL-6 ( r = 0.67, 0.80, P < 0.001). Conclusion:Clonorchis sinensis infection can increase the expression of miR-122 in the host liver tissue, and the miR-122 is closely related to the expression levels of inflammatory cytokines TNF-α and IL-6.
