OBJECTIVE To investigate the effects and mechanism of asperuloside (Asp) on the pyroptosis of intestinal epithelial cells in rats with ulcerative colitis (UC). METHODS The male SD rats were randomly divided into Control group, model group (UC group), ASP low-dose and high-dose groups [Asp-L, Asp-H groups, Asp 35, 70 mg/(kg·d)], ASP high-dose group+AMPK inhibitor Compound C group [Asp-H+Compound C group, Asp 70 mg/(kg·d)+Compound C 0.2 mg/(kg·d)], with 12 rats in each group. Except for Control group, the other groups were injected with 50% ethanol (0.25 mL)+5% 2,4, 6- trinitrobenzene sulfonic acid solution (2 mL/kg) into the intestinal cavity to construct UC model. After modeling, the rats in each drug group were given corresponding drug solution by gavage or (and) tail vein injection, once a day, for 14 consecutive days. After the last administration, the weight of rats in each group was measured, and the length of their colons was measured; disease activity index (DAI) score and colonic mucosal damage index (CMDI) score were performed, and the serum levels of inflammatory factors (interleukin-18, -1β, -6) were detected. The pathological changes of the colon tissue were observed. The expressions of pyroptosis-related proteins [caspase-1, gasdermin D (GSDMD)] in colon tissue, and pathway-related proteins such as adenosine monophosphate-activated protein kinase (AMPK), thioredoxin-interacting protein (TXNIP), NOD-like receptor protein 3 (NLRP3) and apoptosis-associated speck-like protein containing a CARD (ASC) were all detected. RESULTS Compared with Control group, the colon tissue structure of rats in UC group was damaged, with obvious infiltration of inflammatory cells and edema. Their body weight, colon length and phosphorylation level of AMPK protein were significantly reduced or shortened; DAI and CMDI scores, serum levels of inflammatory factors, and the protein expressions of caspase-1, GSDMD, TXNIP, NLRP3 and ASC in colon tissue were increased or upregulated significantly (P<0.05). Compared with UC group, the pathological damage of colon tissue in rats was relieved in Asp-L and Asp-H groups, and all quantitative indicators were significantly improved (P<0.05); the improvement effect of Asp-H group was more significant (P<0.05). Compound C could significantly reverse the improvement effect of high-dose of Asp on the above indicators in UC rats (P<0.05). CONCLUSIONS Asp can improve inflammatory damage in colon tissue and inhibit pyroptosis of intestinal epithelial cells in UC rats, which is associated with the activation of AMPK and inhibition of TXNIP/NLRP3 signaling pathway.

Objective To study the clinical and CT findings of bronchiolar adenoma. Methods Patients diagnosed with bronchiolar adenoma confirmed by surgical pathology at Linyi People's Hospital and Yantai Yuhuangding Hospital from 2016 to 2021 were collected. Their clinical and CT imaging features were retrospectively analyzed. Results Finally, 25 patients were collected, including 6 males and 19 females, aged 32-73 (58.6±10.1) years. The immunohistochemical Ki-67 (MIB1) of all lesions was <5%. The lesions were located in the upper and middle lobe of both lungs in 9 patients, lower lobes in 16 patients, extrapulmonary zone in 22 patients, intrapulmonary middle zone in 3 patients, round in 11 patients, irregular in 14 patients, well-defined in 22 patients, pure ground-glass/mixed ground-glass nodules in 6 patients, solid nodules in 19 patients. There were 11 patients with central small cavity, 18 patients with single bronchioles sign, 19 patients without adhesion with adjacent pleura, and 24 patients without mediastinal lymph node enlargement. Conclusion Bronchiolar adenomas usually occur in the middle-aged and elderly, mostly in the lower lobe of both lungs and the distribution of the peripheral lung field, most of the patients do not have any clinical symptoms, and the postoperative prognosis is good. CT may show large nodules or masses, pure ground-glass/mixed ground-glass nodules, irregular solid nodules and central small cavities. Irregular stellate nodules, central small cavity shadow, and single bronchiolar vascular bundle connected with the lesions are relatively specific imaging findings of bronchiolar adenoma.

Objective To investigate the effect of the long non-coding RNA FGD5 antisense RNA1(lncRNA FGD5-AS1)on myocar-dial cell injury induced by high glucose levels through regulation of the miR-195-5p/Pim-1 proto-oncogene(PIM1)axis.Methods The rat myocardial cell line H9c2 and human myocardial cells were randomly allocated to the control,model,lncRNA FGD5-AS1 overex-pression,miR-195-5p inhibitor,negative control,and lncRNA FGD5-AS1 overexpression+miR-195-5p mimic groups to determine the expression of lncRNA FGD5-AS1,miR-195-5p,and PIM1.In addition,cell proliferation,apoptosis,and pro-inflammatory cytokine levels of the cells in each group were analyzed.Results Compared with the control group,the protein and mRNA expressions of lncRNA FGD5-AS1 and PIM1 and the survival and proliferation rates in H9c2 and human myocardial cells in the model group decreased(P<0.05),and the expression of miR-195-5p,apoptosis rate,and production levels of tumor necrosis factorα(TNF-α)and interleukin-6(IL-6)increased(P<0.05).Overexpression of the lncRNA FGD5-AS1 reversed these pathological changes in model group cells,whereas upregulation of miR-195-5p could weaken the effects of overexpression of lncRNA FGD5-AS1.Conclusion Overexpression of lncRNA FGD5-AS1 enhances the expression of PIM1 by downregulating miR-195-5p,thereby inhibiting high glucose-induced myocyte inflamma-tion,promoting survival and growth,and alleviating apoptotic injury.

Objective:To investigate the safety and short-term efficacy of yttrium-90 [ 90Y] resin microspheres transarterial radioembolization (TARE) for the treatment of initial unresectable malignant hepatic tumor. Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 10 patients with initial unresectable malignant hepatic tumor who were admitted to The First Affiliated Hospital of Army Medical University from June 2022 to June 2023 were collected. All patients were males, aged (57±4)years. Measurement data with normal distribution were represented as Mean± SD, and comparison before and after treatment within the group was conducted using the paired t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison before and after treatment within the group was conducted using the paired rank sum test. Count data were described as absolute numbers or proportions. Results:(1) Pre-treatment assessment. All 10 patients completed pre-treatment assessment, with 8 cases undergoing once of technetium 99-polymerised protein perfusion test and 2 cases under-going ≥ twice of technetium 99-polymerised protein perfusion test. The ratio of uptake of techne-tium 99-polymerised protein in tumor tissue to normal tissue, the hepatopulmonary shunting ratio and the therapeutic requirement of 90Y resin microspheres in 10 patients were 5.8±1.2, 4.8%±0.8% and (1.10±0.20)GBq, respectively. (2) Treatment strategy of 90Y resin microspheres TARE. Of the 10 patients, cases treated with whole tumor radioembolisation, radioembolisation of the main target lesion+non-target lesion radiofrequency ablation, radioembolisation of the main target lesion+non-target lesion iodine-125 particles implantation, radioembolisation of the liver lobe or liver segment were 6, 2, 1, 1, respectively. During the treatment period, one elderly case did not receive target therapy combined with immunotherapy due to intolerance, and the remaining 9 cases received target therapy combined with immunotherapy. Of the 10 patients, there were 7 cases receiving once of 90Y resin microspheres TARE, and 3 cases receiving twice of 90Y resin microspheres TARE. (3) Follow-up. All 10 patients were followed up for 4.5(range, 3.0-12.0)months. During the follow-up, none of patient had adverse event associated with 90Y resin microspheres TARE. The tumor diameter, alpha-fetoprotein (AFP), abnormal prothrombin, alanine aminotransferase (ALT), aspartate amino-transferase (AST), albumin (Alb), total bilirubin (TBiL), glutamyltransferase (GGT) of the 10 patients were 96(72,135)mm, 26(6,833)μg/L, 290(56,2 997)Au/L, (36±13)IU/L, (41+16)IU/L, (40±4)g/L, (15.3±4.1)μmol/L, (99±68)IU/L before receiving 90Y microspheres TARE. The above indicators of the 10 patients were 63(43,97)mm, 4(3,357)μg/L, 38(25, 142) Au/L, (40±16)IU/L, (51±28)IU/L, (39±4)g/L, (14.4±1.2) μmol/L, (134±93)IU/L after 90 days of receiving 90Y microspheres TARE. There were significant differences in tumor diameter and abnormal prothrombin ( Z=-2.08, -2.24, P<0.05) and there was no significant difference in AFP, ALT, AST, Alb, TBil, GGT ( Z=-1.27, t=0.63, 1.69, 1.73, 0.67, 1.30, P>0.05). During the follow-up period, 5 cases achieved clinical complete response, 4 cases achieved clinical partial remission, and 1 case experienced non-target lesion progression within 30 days after receiving 90Y resin microspheres TARE. The disease remission rate and disease control rate of the 10 patients were 9/10 and 9/10, respectively. None of patient died during follow-up period. Conclusion:90Y resin microspheres TARE for the treatment of initial unresectable malignant hepatic tumor is safe and feasible, and can achieve satisfactory short-term efficacy when combined with other treatment methods.

As the research of traditional Chinese medicine (TCM) on knee osteoarthritis (KOA) is progressing, researchers have discovered that a variety of Chinese medicines can delay the progress of KOA by regulating signaling pathways at the molecular level. The Chinese medicines and their active ingredients mentioned in this article are associated with the signaling pathways in KOA. They can regulate the levels of targeted molecules via different signaling pathways to inhibit cartilage inflammatory cytokine, apoptosis, and cartilage matrix degradation and promote chondrocyte autophagy, so as to reduce the synovial inflammatory edema and delay cartilage degeneration. This paper systematically reviews the studies about the TCM intervention of KOA. Baicalein can reduce the inflammatory cytokines and apoptosis and promote the autophagy of chondrocytes by blocking the phosphatidylinositol-3 kinase/protein kinase (PI3K/Akt) signaling pathway. Cornuside I can decrease the phosphorylation activity of Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) pathway to reduce synovial inflammation and delay cartilage matrix degeneration. Salvianolic acid A can reduce inflammation and cartilage matrix degradation by inhibiting the phosphorylation of the nuclear factor-κB (NF-κB) pathway. Emodin can reduce the activity of Wnt/β-catenin pathway to inhibit the decomposition of collagen and proteoglycan. Myristicoside can inhibit apoptosis by blocking the p38 mitogen-activated protein kinase (p38 MAPK) signaling pathway. Akebia saponin D can enhance the activity of nuclear factor E2-related factor 2/heme oxygenase 1(Nrf2/HO-1) pathway to inhibit oxidative stress in chondrocytes. The saponins in Achyranthis Bidentatae Radix reduce cartilage matrix degradation by enhancing the transforming growth factor-β (TGF-β)/Smad signaling pathway. Crocin inhibits the cartilage inflammation and apoptosis factor increase by stimulating the activity of hippo-Yes-associated protein (Hippo-YAP). Ligustrazine blocks the Notch pathway to improve the morphology and abnormality of chondrocytes. Oleanolic acid reduces the destruction and degeneration of cartilage matrix via the estrogen signaling pathway. The above summary aims to provide references for future clinical and experimental research on KOA.
