RESUMEN
Objective:To investigate the influencing of portal vein embolization (PVE) and PVE combined with transcatheter arterial chemoembolization (TACE) on secondary hepatectomy and prognosis of patients with initially unresectable hepatocellular carcinoma (HCC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 102 patients with initially unresectable HCC who were admitted to the Third Affiliated Hospital of Naval Medical University from October 26,2015 to December 31,2022 were collected. There were 82 males and 20 females, aged 52(range,25?73)years. Of 102 patients, 72 cases undergoing PVE combined with TACE were set as the PVE+TACE group, and 30 cases undergoing PVE were set as the PVE group. Observation indicators: (1) surgical resection rate of secondary hepatectomy and increase of future liver remnant (FLR); (2) situations of secondary hepatectomy; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the Mann-Whitney U test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and Log-Rank test was used for survival analysis. Results:(1) Surgical resection rate of secondary hepatectomy and increase of FLR. The surgical resection rate of secondary hepatectomy in the PVE+TACE group and the PVE group were 72.2%(52/72) and 53.3%(16/30), respectively, showing no significant difference between the two groups ( χ2=3.400, P>0.05). The surgical waiting time, increasing volume of FLR, growth rate of FLR in the 52 patients of PVE+TACE group receiving secon-dary hepatectomy were 20(range, 14?140)days, 140(range, 62?424)mL, 9.8(range, 1.5?26.5)mL/day, respectively. The above indicators in the 16 patients of PVE group receiving secondary hepatectomy were 16(range, 12?35)days, 160(range, 95?408)mL, 10.5(range, 1.2?28.0)mL/day, respectively. There was no significant difference in the above indicators between the 52 patients of PVE+TACE group and the 16 patients of PVE group ( Z=1.830, 1.498, 1.266, P>0.05). (2) Situations of secondary hepatectomy. The operation time, rate of tumor necrosis (>90%, 60%?90%,<60%), cases with complications ≥ grade Ⅲa in the 52 patients of PVE+TACE group receiving secondary hepatectomy were 200(range, 125?420)minutes, 8, 4, 40, 28, respectively. The above indicators in the 16 patients of PVE group receiving secondary hepatectomy were 170(range, 105?320)minutes, 0, 0, 16, 4, respectively. There were significant differences in the above indicators between the 52 patients of PVE+TACE group and the 16 patients of PVE group ( Z=2.132, ?2.093, χ2=4.087, P<0.05). (3) Follow-up. Sixty-eight patients who completed the surgery were followed up for 40(range, 10?84)months. The 1-, 3-, 5-year recurrence free survival rate in the 52 patients of PVE+TACE group receiving secondary hepatectomy were 73.0%, 53.3%, 35.4%, respectively. The above indicators in the 16 patients of PVE group were 62.5%, 37.5%, 18.8%, respectively. There was a significant difference in the recurrence free survival rate between the 52 patients of PVE+TACE group and the 16 patients of PVE group ( χ2=4.035, P<0.05). The 1-, 3-, 5-year overall survival rate in the 52 patients of PVE+TACE group receiving secondary hepatectomy were 82.5%, 61.2%, 36.6%, respectively. The above indica-tors in the 16 patients of PVE group receiving secondary hepatectomy were 68.8%, 41.7%,20.8%, respectively. There was a significant difference in the overall survival rate between the 52 patients of PVE+TACE group and the 16 patients of PVE group ( χ2=4.767, P<0.05). Conclusion:Compared with PVE, PVE+TACE as stage Ⅰ surgery can increase the surgical resection rate of secondary hepatec-tomy and the recurrence free survival rate of patients with initially unresectable HCC, prolong the long-term survival time, but not influence the growth rate of FLR.
RESUMEN

RESUMEN
Aim To anticipate the mechanism of zuka- mu granules (ZKMG) in the treatment of bronchial asthma, and to confirm the projected outcomes through in vivo tests via using network pharmacology and molecular docking technology. Methods The database was examined for ZKMG targets, active substances, and prospective targets for bronchial asthma. The protein protein interaction network diagram (PPI) and the medication component target network were created using ZKMG and the intersection targets of bronchial asthma. The Kyoto Encyclopedia of Genes and Genomics (KEGG) and gene ontology (GO) were used for enrichment analysis, and network pharmacology findings were used for molecular docking, ovalbumin (OVA) intraperitoneal injection was used to create a bronchial asthma model, and in vivo tests were used to confirm how ZKMG affected bronchial asthma. Results There were 176 key targets for ZKMG's treatment of bronchial asthma, most of which involved biological processes like signal transduction, negative regulation of apoptotic processes, and angiogenesis. ZKMG contained 194 potentially active components, including quercetin, kaempferol, luteolin, and other important components. Via signaling pathways such TNF, vascular endothelial growth factor A (VEGFA), cancer pathway, and MAPK, they had therapeutic effects on bronchial asthma. Conclusion Key components had strong binding activity with appropriate targets, according to molecular docking data. In vivo tests showed that ZKMG could reduce p-p38, p-ERKl/2, and p-I
RESUMEN
This study aimed to investigate the effect of Flos Farfarae (FF) fumigation on cigarette smoke-induced lung injury mice, and analyze the metabolic profile of lung tissue by metabolomics. All animal experiments were conducted under the guidance and approval of the Animal Ethics Review Committee of Shanxi University (Approval number: SXULL2019014). By using HS-GC-MS to analyze volatile components of Flos Farfarae, 23 compounds were identified. The results showed that FF fumigation improved the lung tissue morphology of cigarette smoke-induced lung injury mice, lowered the levels of interleukin 6 (IL-6) and interleukin-1β (IL-1β). The lung tissue samples were applied for metabolomic analysis based on UHPLC-QTOF MS, the results showed that 70 metabolites were changed in the lung tissue of mice after cigarette exposure, and 35 of them could be regulated, including lysophosphatidylcholine (LPC), 12-HETE, adenosine, and xanthine. These metabolites, such as LPC, 12-HETE, adenosine, and xanthine were mainly associated with the body's inflammatory response. It was observed that these metabolites are primarily involved in purine metabolism, arachidonic acid metabolism, phospholipid metabolism, and pyruvate metabolism pathways. These findings suggest that the volatile terpenoids in the FF may regulate the metabolites associated with the inflammatory response in the lung tissue, such as lysophosphatidylcholine, 12-HETE, and adenosine, which could further alleviate lung inflammation induced by cigarette smoke through the metabolic pathways of purine metabolism and others. This study proved the scientific basis of the traditional application of FF fumigation, and provided a theoretical basis for the further product development.
RESUMEN
ObjectiveThis study aims to investigate the effect of modified Baitouwengtang (MBTWD) on tumor growth and the number of tumor-associated macrophages (TAMs) in tumor tissue of MC38 cell tumor-bearing mice with colorectal cancer and explores whether MBTWD mediates the remodeling of TAM phenotype to play an immunologically antitumor effect. MethodFirstly, The C57BL/6 mouse tumor model grafted subcutaneously was established, and then model mice were classified into a model group, positive control group(3 mg·kg-1), and MBTWD groups with high and low dosages(23.43、46.86 g·kg-1), with 10 mice in each group. In addition, 10 healthy mice were set as the blank group, and the changes in body weight, tumor volume, and survival status of mice in each group were observed. Tumor tissue, spleen, and peripheral blood were collected to calculate the tumor volume change, tumor inhibition rate, and spleen mass. Hematoxylin-eosin (HE) staining was used to observe the morphological changes of tumor tissue, and an immunofluorescence assay was used to detect the expression levels of CD4, CD8, and CD206 in tumor tissues of tumor-bearing mice. The secretion levels of transforming growth factor (TGF)-β, interleukin (IL)-6, and chemokine (C-C Motif) ligand 2 (CCL2) in peripheral serum were measured by using enzyme-linked immunosorbent assay (ELISA). Secondly, a co-culture model induced by IL-4 in vitro of MC38 cells and murine monocytic macrophage RAW264.7 cells was established. Cell proliferation and activity assay (CCK-8) was used to detect the inhibitory effect of MBTWD containing serum on cell proliferation. A transwell experiment was used to detect the effect of IL-4-induced M2 macrophages on the invasion of MC38 cells. Flow cytometry was used to detect the expression of CD86 on the membrane of M2 macrophages induced by IL-4 with MBTWD containing serum. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the effect of MBTWD containing serum on the mRNA expression levels of M1 macrophage-related polarization factors CD86, nitric oxide synthase (iNOS), and IL-12, as well as M2 macrophage-related polarization factors CD206, CD163, and IL-10 after co-cultivation. Finally, the protein expression levels of colony-stimulating factor 1 receptor (CSF1R), stimulator of interferon genes (STING), and TANK binding kinase 1 (TBK1) in tumor tissues of tumor-bearing mice were detected by Western blot. ResultIn vivo experimental results show that compared with the model group, the MBTWD can significantly inhibit the tumor growth of tumor-bearing mice. Immunofluorescence experiments show that the MBTWD can increase the number of CD8+ T cell infiltration in tumor tissue of tumor-bearing mice, reduce the number of CD206+ TAMs infiltration, and down-regulate the secretion levels of cytokines IL-6, TGF-β, and CCL2 in peripheral blood of tumor-bearing mice. The results of in vitro experiments show that the MBTWD containing serum has no obvious inhibitory effect on cell proliferation, but the cell supernatant after co-cultivation with RAW264.7 cells can inhibit the proliferation activity of MC38 cells, and the invasion ability of MC38 cells is enhanced by IL-4-induced M2 macrophages. However, this effect can be inhibited in a concentration-dependent manner by the MBTWD containing serum. At the same time, the results of Real-time PCR show that the MBTWD containing serum can up-regulate the mRNA expression levels of M1 macrophage-related polarization factors CD86, iNOS, and IL-12 and down-regulate those of M2 macrophage-related polarization factors CD206, CD163, and IL-10. Flow cytometry results also confirm that the MBTWD containing serum can increase the number of repolarized CD86+ M1 macrophages, indicating that MBTWD can induce M2 macrophages to repolarized M1 macrophages to play an anti-tumor growth role. Finally, Western blot results show that MBTWD can down-regulate the expression of CSF1R protein and up-regulate that of STING and TBK1 proteins in tumor tissue of tumor-bearing mice. ConclusionMBTWD can down-regulate the infiltration number of CD206+ TAMs and increase the infiltration of CD8+ T cells, thereby playing an immunologically antitumor effect on the growth inhibition of colorectal cancer, which may be related to regulating CSF1R signaling and then activating STING/TBK1 signaling pathway to induce phenotypic remodeling of TAMs.
RESUMEN
Alkaloids are a class of naturally occurring bioactive compounds that are widely distributed in various food sources and Traditional Chinese Medicine. This study aimed to investigate the therapeutic effects and underlying mechanisms of alkaloid extract from Codonopsis Radix (ACR) in ameliorating hepatic lipid accumulation in a mouse model of non-alcoholic fatty liver disease (NAFLD) induced by a high-fat diet (HFD). The results revealed that ACR treatment effectively mitigated the abnormal weight gain and hepatic injury associated with HFD. Furthermore, ACR ameliorated the dysregulated lipid metabolism in NAFLD mice, as evidenced by reductions in serum triglyceride, total cholesterol, and low-density lipoprotein levels, accompanied by a concomitant increase in the high-density lipoprotein level. ACR treatment also demonstrated a profound anti-oxidative effect, effectively alleviating HFD-induced oxidative stress and promoting ATP production. These effects were achieved through the up-regulation of the activities of mitochondrial electron transfer chain complexes I, II, IV, and V, in addition to the activation of the AMPK/PGC-1α pathway, suggesting that ACR exhibits therapeutic potential in alleviating the HFD-induced dysregulation of mitochondrial energy metabolism. Moreover, ACR administration mitigated HFD-induced endoplasmic reticulum (ER) stress and suppressed the overexpression of ubiquitin-specific protease 14 (USP14) in NAFLD mice. In summary, the present study provides compelling evidence supporting the hepatoprotective role of ACR in alleviating lipid deposition in NAFLD by improving energy metabolism and reducing oxidative stress and ER stress. These findings warrant further investigation and merit the development of ACR as a potential therapeutic agent for NAFLD.

With the development of medical technology, tumor vaccines as a novel precise immunotherapy approach have gradually received attention in clinical applications. Against the backdrop of the global corona virus disease 2019 (COVID-19) outbreak, vaccine technology has further advanced. Depending on the types of antigens, tumor vaccines can be divided into whole-cell vaccines, peptide vaccines, messenger ribonucleic acid (mRNA) vaccines, recombinant virus vaccines, etc. Although some tumor vaccines have been marketed and achieved certain therapeutic effects, the results of tumor vaccines in clinical trials have been unsatisfactory in the past period. With the maturation of next-generation sequencing (NGS) technology and the continuous development of bioinformatics, dynamic monitoring of the entire process of tumor subpopulation development has become a reality, which has laid a solid foundation for personalized, neoantigen-centered therapeutic tumor vaccines. This article reviews the recent developments of tumor vaccines of different types, starts with lung cancer and summarizes the achievements of tumor vaccines in clinical applications, and provides an outlook for the future development of antigen-centered tumor vaccines. .

The use of ARRIVE 2.0 guidelines not only enriches the details of animal experimental research reports, ensuring that information on animal experimental results is fully evaluated and utilized, but also enables readers to understand the content expressed by the author accurately and clearly, promoting the transparency and integrity of the fundamental research review process. At present, the ARRIVE 2.0 guidelines have been widely adopted by international biomedical journals. This article is a Chinese translation based on the best practices of international journals following the ARRIVE 2.0 guidelines in international journals, specifically for the complete interpretation of the ARRIVE 2.0 guidelines published in the PLoS Biology journal in 2020 (original text can be found at https://arriveguidelines.org). The fourth part of the article includes the items 1-5 of ARRIVE 2.0 Recommended 11 section, which covers "Abstract" "Background" "Objectives" "Ethical statement" and "Housing and husbandry". Its aim is to promote the full understanding and use of the ARRIVE 2.0 guidelines by domestic researchers, enhance the standardization of experimental animal research and reporting, and promote the high-quality development of experimental animal technology and comparative medicine research in China.
RESUMEN
ObjectiveEstablish an animal model of preeclampsia in goats, collect data on various physiological indicators and maternal biological characteristics of the disease model to compare with clinical feature of the disease in humans, provide reference for the prevention and treatment of preeclampsia in humans.Methods Twenty-three goats bred in Chongming district were divided into three groups: Control group, no surgical procedure was performed on animals of this group; sham group, ewes in this group underwent the sham operation on the 100±5th day of gestation, and only the uterine artery was exposed and dissociated; surgical group, a silver vascular clamp was clipped on one side of the uterine body artery of the ewe to narrow the inner diameter of the artery at the same gestation period (100±5) days. Heart rate and hindlimb blood pressure were continuously monitored in control and surgical ewes from 100 to 140 d of gestation, and blood flow data within the lateral branches of the uterine arteries of ewes in the sham group were collected using a hemodynamometer in combination with a hemodynamic probe and an animal physiological signal collector, as well as changes in blood flow within the uterine arteries in the lateral branches of the uterine arteries of the surgical group before and after placement of vascular clips in the surgical ewes. At the expected date of delivery, jugular vein blood was taken from ewes for routine blood test, creatinine, urea nitrogen, and blood ion analysis; urine was also collected from ewes in each group for analysis of urinary protein and urinary creatinine. All experimental groups were subjected to cesarean section on the 140±5th day of gestation in ewes, and then liver, kidney, uterus and placenta tissues were taken from ewes in each group and stained with HE for pathological observation. Results After 15 minutes of preeclampsia modeling surgery, blood flow volume remained stable in the vessel stenosis segment and the volume differential was relatively reduced in comparison to the control group and sham group (P<0.05,P<0.01). Compared with the control group, the ewes in the surgical group showed prenatal changes such as increased serum osmolality, decreased hemoglobin, increased blood glucose and urea nitrogen values, as well as increased levels of calcium, sodium, and chloride ions (all P<0.05) and proteinuria, with urinary creatinine and urinary protein-creatinine ratios were significantly higher than those in the control group and sham group (all P<0.05). The elastic lamina of the uterine body arteries on the operated side of the animals in the surgical group was thicker than that on the opposite side, but the structure was loose. The placenta on the operated side showed pathological changes such as cell interstitial swelling and inflammatory cell infiltration. The above physiological index characteristics were more consistent with the clinical features of human preeclampsia disease.Conclusion In this experiment, we successfully constructed a goat preeclampsia model and obtained data on relevant physiological indexes of this model, which further verified the correlation between preeclampsia disease and uterine artery lesions.
RESUMEN
Improving the reproducibility of biomedical research results is a major challenge.Researchers reporting their research process transparently and accurately can help readers evaluate the reliability of the research results and further explore the experiment by repeating it or building upon its findings. The ARRIVE 2.0 guidelines, released in 2019 by the UK National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs), provide a checklist applicable to any in vivo animal research report. These guidelines aim to improve the standardization of experimental design, implementation, and reporting, as well as the reliability, repeatability, and clinical translatability of animal experimental results. The use of ARRIVE 2.0 guidelines not only enriches the details of animal experimental research reports, ensuring that information on animal experimental results is fully evaluated and utilized, but also enables readers to understand the content expressed by the author accurately and clearly, promoting the transparency and integrity of the fundamental research review process.
