Bile-processed Coptidis Rhizoma（B-pCR）， first documented in Shengji Zonglu， is a unique processed products of Coptidis Rhizoma（CR） characterized by "mutual enhancement processing" and "enhancing the cold property of cold-natured herbs". Pig bile can enhance the bitter and cold properties of CR， yielding potent effects in purging excess fire from the liver and gallbladder. The processing increases the dissolution of alkaloids such as berberine， coptisine， and palmatine， while introducing bile acids from pig bile， including taurine-type and glycine-type cholic acids. This enhances its pharmacological effects， such as antipyretic activity， regulation of glucose and lipid metabolism disorders， and intestinal absorption. Traditional processing techniques and quality standards for B-pCR are outlined in the Shanghai Traditional Chinese Medicine（TCM） Decoction Pieces Processing Standard and the Gansu TCM Processing Standard. However， incomplete specifications for critical process parameters and quality criteria significantly impact its production and clinical application. A review of research over the past two decades on the processing history， process optimization， quality evaluation， material basis， and changes in pharmacological effects and properties of B-pCR reveals that the pretreatment method and dosage of pig bile， and processing temperature are key factors influencing its quality. Furthermore， current quality standards lack specific indicators. Additionally， the enhancement of the cold property and medicinal efficacy direction of B-pCR is not only associated with changes in alkaloid groups but also depend on the synergistic effects of bile acids. This review can provide insights for improving the quality evaluation system of B-pCR.

Objective:To discuss the changes of adenosine deaminase 2(ADA2)activity in the serum of the systemic lupus erythematosus(SLE)patients,and to clarify its clinical value in the diagnosis and disease assessment of the SLE patients.Methods:According to the inclusion and exclusion criteria,69 SLE patients(SLE group)and 69 healthy controls(control group)were enrolled as study subjects.The disease activity of SLE patients was evaluated by SLE Disease Activity Index(SLEDAI).The ADA2 activity in the serum of the subjects in both groups was detected.The patients were further divided into subgroups based on the presence or absence of the following clinical symptoms:arthritis,myositis,hematuria,proteinuria,pyuria,alopecia,new rash,mucosal ulcer,pleuritis,hypocomplementemia,elevated anti-double-stranded DNA(anti-dsDNA)antibody,thrombocytopenia,and leukopenia.The differences in serum ADA2 activity between joint symptomatic group and joint asymptomatic group were analyzed.The diagnostic efficacy of serum ADA2 activity was evaluated by receiver operating characteristic(ROC)curve analysis.The correlation between ADA2 activity and disease activity in the SLE patients was analyzed by Spearman correlation analysis.Results:Compared with control group,the ADA2 activity in the serum of the patients in SLE group was significantly increased(P<0.01).The ROC analysis results showed that when the cut-off value of ADA2 activity was set at 8.5 U·L-1,the diagnostic performance was optimal,with an area under the curve(AUC)of 0.879(95%CI:0.817-0.940),the specificity was 89.86%,and the sensitivity was 75.36%.The serum ADA2 activity was positively correlated with disease activity in the SLE patients(r=0.32,P=0.007).The subgroup analysis of clinical symptoms results showed that the serum ADA2 activity in the SLE patients with symptoms was significantly higher than that in the SLE patients without symptoms(P<0.01).No significant differences were observed in serum ADA2 activity between the SLE patients with and without myositis,hematuria,proteinuria,pyuria,alopecia,new rash,mucosal ulcer,pleuritis,hypocomplementemia,elevated anti-dsDNA antibody,thrombocytopenia,or leukopenia(P>0.05).Conclusion:The serum ADA2 activity is increased in the SLE patients and can serve as a diagnostic marker for SLE.Serum ADA2 activity is positively correlated with disease activity and is associated with arthritis in the SLE patients,suggesting its potential as an indicator for disease assessment and monitoring.

Objective To find out whether photobiomodulation(PBM)can mitigate cognitive dysfunction caused by chronic stress by affecting levels of adenosine triphosphate(ATP)and adenosine receptors.Methods Twenty-four C57BL/6J mice were randomly divided into a control group,a stress group,and a treatment group.Chronic unpredictable mild stress was used to establish a mouse model of stress.Six weeks into modeling,the treatment group was subjected to one week of PBM interventions.Behavioral tests were conducted to observe behavioral changes in the mice.Western blotting(WB)was used to detect the expressions of A1,A2B,and A3 adenosine receptors in the hippocampus and prefrontal cortex of mice in the three groups.Twelve C57BL/6J mice were randomly divided into a control group and an intervention group.The intervention group received a week of PBM interventions and underwent behavioral testing.WB was used to detect the expression changes of A1,A2B,and A3 adenosine receptors in the hippocampus and prefrontal cortex in both groups.Immunofluorescence assay was adopted to detect the expression of c-Fos in the hippocampus of mice in the two groups.The ATP assay kit made by Beyotime Biotechnology Co.,Ltd.was used to measure changes in ATP contents in the hippocampus and prefrontal cortex tissues of mice.Cell experiments were conducted to verify the effect of PBM on intracellular ATP contents.Results Mice in the stress group covered a similar distance to the control group,but finished far fewer platform crossings.There was no significant difference between the treatment group and the control group in the number of times of platform crossings,but compared favorably with the stress group where the levels of adenosine receptors in the hippocampus and prefrontal cortex were lower,but were increased by PBM.After PBM interventions in normal mice,platform crossings were increased significantly compared to the control group.PBM also raised adenosine receptor levels and ATP contents in the hippocampus and prefrontal cortex,and increased hippocampal c-Fos expressions.In vitro,PBM elevated intracellular ATP levels.Conclusion PBM may improve chronic stress-induced cognitive dysfunction by regulating ATP levels and adenosine receptor expressions,thereby modulating neuronal responsiveness in the hippocampus.

Objective To investigate the effect of MALAT1 expressions on cell proliferation and apoptosis in astrocytes by regulating mitogen-activated protein kinase(MAPK)/extracellular signal-regulated kinase(ERK1,2)pathway.Methods The MALAT1 gene was knocked down and over-expressed in C8-D1A cells by lentiviral and plasmid vectors,respectively.The expressions of MALAT1,cell proliferation-related markers(Ki67,MCM2,PCNA)and apoptosis-related proteins(Caspase-3,Bax,Bcl-2)were detected by quantitative real-time polymerase chain reaction(qPCR).CCK-8 assay and flow cytometry were used for cell proliferation and apoptosis in C8-D1A cells.Immunofluorescence was adopted to detect the protein expressions of Caspase-3 and Ki67.Western blotting was used to detect the protein expressions of Caspase-3,Bax,Bcl-2,ERK1/2,p-ERK1/2,p38MAPK and p-p38MAPK.Results Compared with the control group,over-expressed MALAT1 inhibited cell proliferation and induced cell apoptosis in C8-D1A cells while the knockdown of MALAT1 significantly enhanced cell proliferation and anti-apoptotic ability in C8-D1A cells.The proportion of C8-D1A cells in G0/G1-phase and G2/M-phase was higher than in the control group as evidenced by flow cytometry,but was lower in S-phase.Meanwhile,data showed that Caspase-3 was increased while p-ERK1/2 was decreased in terms of protein levels.The mRNA expressions of Ki67 and PCNA were decreased.After knockdown of MALAT1,the proportion of C8-D1A cells in S-phase was higher,but was lower in G2/M-phase.The protein expressions of Caspase-3 and Bax decreased while those of p-ERK1/2 and p-p38MAPK increased.The mRNA expressions of Ki67,MCM2 and PCNA were increased.The differences were all statistically significant(P＜0.05).Conclusion MALAT1 promotes astrocyte apoptosis and inhibits proliferation by regulating the MAPK/ERK1,2 signaling pathway.

Objective:To investigate the synergistic effects and molecular mechanisms of dihydroartemisinin(DHA) and sorafenib(SOR) in inducing ferroptosis in anaplastic thyroid cancer(ATC) cells.Methods:CCK-8 and flow cytometry assays were performed to detect the effects of DHA and SOR on the proliferation and ferroptosis of ATC cells(CAL-62). Real-time fluorescence quantitative PCR and Western blotting assays were performed to detect the expressions of ferroptosis-related genes glutathione peroxidase 4(GPX4), solute carrier family 7 member 11 gene(SCL7A11), lipoxygenase-15(LOX-15), and p53. The levels of iron death intermediate metabolites including lactate dehydrogenase(LDH), glutathione(GSH), malondialdehyde(MDA), ferrous ion(Fe 2+ ), nitric oxide(NO), and reactive oxygen species(ROS)were measured by corresponding assay kits. The corresponding inhibition of DHA and SOR on ATC in vivo was analyzed in a tumor model in nude mice. Results:Compared with the control group, DHA, SOR, and DHA+ SOR treatment significantly inhibited cell proliferation and apoptosis in a dose-dependent manner( P<0.001), with increased LDH, Fe 2+, MDA, and ROS contents and reduced GSH activity( P<0.001), which were promoted by ferrous sulfate(FeSO 4)and reversed by ferroptosis inhibitor-1. Compared with the control group and the drug monotherapy group, 15-LOX-2 and p53 expressions were upregulated in DHA+ SOR group while GPX4 and SCL7A11 expressions were decreased( P<0.001), without significant difference in 15-LOX-1 protein content. In addition, NO level was significantly increased in DHA+ SOR group( P<0.001). DHA and SOR inhibited tumor growth of ATC in vivo. Conclusion:DHA and SOR synergistically induced ferroptosis via upregulating the expression of 15-LOX-2 gene and inhibiting NO synthesis in ATC cells.

【Objective】 To compare the clinical efficacy of robot-assisted and open surgery in the treatment of renal carcinoma with inferior vena cava cancer thrombus, and to analyze the safety and feasibility of robot-assisted radical nephrectomy. 【Methods】 Clinical data of 55 patients surgically treated for renal carcinoma with Mayo Ⅰ-Ⅲ inferior vena cava tumor thrombus during Dec.2015 and Dec.2021 were retrospectively analyzed. Based on the operation methods, the patients were divided into the robotic surgery group (n=36) and open surgery group (n=19). The perioperative data, oncological results and survival of the two groups were compared. 【Results】 All operations were successful. The median operation time was 176 (IQR:137-234) min, and grade Ⅲ and above complications occurred in 9(16.4%) cases. The robotic surgery group had lower intraoperative blood loss [300 (IQR:200-625) mL vs.1 000 (IQR:600-1 184) mL] and blood transfusion ratio [(20/36) vs. (18/19)] than the open surgery group, but higher postoperative hemoglobin level[109(98-120) g/L vs. 90(84-100) g/L]. During a median follow-up of 26 (IQR:19-39) months, 19(34.5%) patients developed new metastases and 12(21.8%) patients died. The postoperative tumor-specific survival (HR=0.39, 95%CI:0.13-1.16, P=0.090) and overall survival (HR=0.71, 95%CI:0.22-2.23,P=0.554) were not significantly different between the two groups. 【Conclusion】 There are no significant differences in the incidence of postoperative complications, tumor-specific survival and overall survival between robot-assisted and open surgery for Mayo Ⅰ-Ⅲ inferior vena cava tumor thrombus, but the intraoperative blood loss in robotic group is lower than that in the open surgery group.

The surgical parameters, perioperative complications and follow-up outcomes were compared between the two groups. 【Results】 All operations were successful. Compared with the robot group, the open group had a higher incidence of clinical symptoms (93.3% vs.44.4%, P=0.015) and larger maximum tumor diameter (124 mm vs.95 mm, P=0.021). There were no significant differences in other preoperative characteristics between the two groups. The robot group had less intraoperative blood loss (100 mL vs.800 mL, P=0.006) and lower blood transfusion rate (0% vs. 60.0%, P=0.007) than the open group. During the median follow-up of 50 (range: 25-67) months, 4 patients in the open group and 1 in the robot group developed new metastases, and 4 patients in the open group died due to advanced tumor stage. 【Conclusion】 Robot-assisted radical nephrectomy is safe in the treatment of complex and large renal tumors, and causes less intraoperative blood loss than open surgery.

Background::CD5L (CD5 molecular-like) plays an important role in lipid metabolism and immune regulation. This study aimed to investigate the roles of CD5L on liver hepatocellular carcinoma (LIHC).Methods::We analyzed the CD5L mRNA expression and its potential prognostic value based on The Cancer Genome Atlas and Gene Expression Omnibus databases. Immunohistochemical analysis was used to investigate the CD5L levels in LIHC tissues. Serum CD5L levels in LIHC were detected by enzyme-linked immunosorbent assay. Cell Counting Kit-8 (CCK-8) assay was used to investigate the effect of CD5L treatment on HepG2 and QSG-7701 cell proliferation. CD5L expression correlated genes were exhumed based on the LinkedOmics. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses for CD5L associated genes were performed. The correlation between CD5L and tumor immune infiltration was analyzed by using Tumor Immune Estimation Resource (TIMER) 2.0.Results::CD5L mRNA and protein levels were significantly decreased in LIHC tumor tissue compared with non-tumor control tissues. Moreover, serum CD5L levels were significantly lower in LIHC patients than that in healthy subjects. Gene Expression Profiling Interactive Analysis 2 and Kaplan-Meier plotter analysis showed that a high-CD5L expression was correlated with favorable overall survival in LIHC patients, except the LIHC patients with hepatitis virus. CCK-8 results showed that CD5L treatment significantly decreased HepG2 cell proliferation in a concentration-dependent manner, and CD5L treatment had no effect on the proliferation of non-tumor hepatocyte line QSG-7701. CD5L associated genes were enriched in the immune response biological process, and CD5L expression levels were positively correlated with the immune infiltrates of CD8 + T cell and M1 macrophage cells but negatively correlated with CD4 + T cells and M0 macrophage cell infiltration. Conclusions::Exogenous CD5L inhibits cell proliferation of hepatocellular carcinoma. CD5L may act as a role of prognostic marker.
