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.

Type 1 diabetes mellitus is a chronic autoimmune disease caused by the destruction of pancreatic islet β cells. Pancreatic islet transplantation provides a treatment method for patients with type 1 diabetes mellitus to restore endogenous insulin secretion. However, some problems limit the widespread application of islet transplantation, such as the shortage of donors and post-transplantation rejection damage. Mesenchymal stem cell-derived exosome (MSC-Exo) has become a potential tool for islet transplantation therapy due to their immunomodulatory and tissue repair capabilities. MSC-Exo shows great promise for application, because of low immunogenicity, easily being stored and transported, and the potential as drug delivery vehicles. However, challenges such as preparation, purification, standardization and safety verification need to be overcome before converting MSC-Exo into clinical practice. Therefore, this article reviews the application and potential advantages of MSC-Exo in islet transplantation, aiming to providing more effective and safer treatment options for patients with type 1 diabetes mellitus.

Objective: To explore the safety and feasibility of the disconnection of the left renal artery preferentially during robot-assisted inferior vena cava (IVC) thrombectomy for patients with left renal cell carcinoma and tumor emboli. Methods: Clinical data of 7 patients who underwent robot-assisted IVC thrombectomy and radical nephrectomy in the First Affiliated Hospital of Zhengzhou University during Dec.2021 and Oct.2024 were retrospectively analyzed.Thrombectomy was performed first，followed by nephrectomy. The “IVC-first, kidney-last”robotic technique was developed to minimize chances of IVC thrombus. When patients in left lateral decubitus position, the left renal artery was severed from the right side through the inferior vena cava and abdominal aorta. After removal of thrombus from IVC was completed, patients changed to the right lateral position to complete radical left nephrectomy. Results: Imaging examinations revealed that the median diameter of the renal cell carcinomas was 83(46-99) mm; the median length of the inferior vena cava cancerous emboli was 49(2-91) mm.According to the Mayo classification，the cancerous emboli were gradeⅠ in 2 cases，gradeⅡ in 4 cases，and grade Ⅲ in 1 case.All surgeries were successful.The median operation time was 248(201-331) minutes，blood loss 500(200-1000) mL，and 6 cases required intraoperative blood transfusion.The median time for transition into the intensive care unit was 1(1-4) days，and drainage tube removal 6(5-12) days.Serum creatinine increased significantly in 5 cases，4 of which returned to normal after 1 week，but 1 had renal insufficiency (creatinine 166 μmol/L).Chylous fistula occurred in 1 patient，and lower extremity venous thrombosis developed in 3 patients.Pathological examinations indicated 6 cases of renal cell carcinoma and 1 case of MiT family translocation renal cell carcinoma.During the median follow-up of 17(1-35) months，5 cases were tumor-free，while 2 had lung and retroperitoneal metastases.They received targeted therapy of axitinib combined immunotheraphy and lived with tumors. Conclusion: In the left lateral position for left renal cell carcinoma with cancerous emboli，robot-assisted laparoscopic thrombectomy by crossing the inferior vena cava and abdominal aorta and disconnecting the left renal artery first is safe and feasible.

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.

AIM:Bone morphogenetic protein 7(BMP7)reduces the expression of Yes-related protein 1(YAP1)by down-regulating Ajuba level and decreasing extracellular matrix(ECM)deposition.This study aimed to inves-tigate the influence of these factors on modifying the degree of renal fibrosis in rats with diabetic nephropathy.METH-ODS:Eighteen Sprague-Dawley(SD)rats were randomly divided into three groups:the normal control(NC)group,the diabetes mellitus(DM)group,and the DM group treated with BMP7 overexpressing adeno-associated virus(DM+rAAV-BMP7).Each group consisted of six rats.Diabetic kidney disease(DKD)was established in the DM and DM+rAAV-BMP7 groups by injecting 55 mg/kg streptozotocin(STZ)via the tail vein.NRK-52E cells were divided into three groups:the normal glucose(NG)group,the high glucose(HG)group,and the high glucose group treated with recombinant hu-man BMP7(HG+rhBMP7)group.Pathological changes in renal tissues were observed using hematoxylin and eosin(HE)and Sirius red staining.Immunohistochemical staining was performed to examine the expression sites of Ajuba and YAP1 in the renal cortex.Western blot analysis was conducted to determine the expression levels of BMP7,Ajuba,YAP1,colla-gen type Ⅲ(Col-Ⅲ),and fibronectin(FN)in the rat renal cortex and NRK-52E cells.RT-qPCR was used to measure the mRNA levels of Ajuba and YAP1 in the rat renal cortex.RESULTS:Biochemical indices revealed significantly ele-vated levels of blood glucose,serum creatinine,triglycerides,total cholesterol,and 24-hour urinary protein in the DM group compared to the NC group(P<0.05).In the DM+rAAV-BMP7 group,the levels of serum creatinine,24-hour uri-nary protein,triglycerides,and total cholesterol were lower than those in the DM group(P<0.05).Pathological staining demonstrated that the renal interstitium of the DM group exhibited inflammatory cell infiltration,fibrous tissue,collagen fi-ber deposition,disordered renal tubule arrangement,atrophy,and vacuolar degeneration,which were ameliorated in the DM+rAAV-BMP7 group.Immunohistochemistry revealed that Ajuba and YAP1 were mainly expressed in the cytoplasm and nucleus,with high expression in the cytoplasm of the DM group,which was significantly decreased in the DM+rAAV-BMP7 group.Western blot results indicated that the protein levels of FN,Col-Ⅲ,Ajuba,and YAP1 were up-regulated in the DM and the HG groups(P<0.05),but significantly down-regulated in the DM+rAAV-BMP7 group(P<0.05).RT-qP-CR results demonstrated that the mRNA levels of Ajuba and YAP1 were higher in the DM group and significantly lower in the DM+rAAV-BMP7 group(P<0.05).CONCLUSION:The overexpression of BMP7 can ameliorate renal fibrosis in rats with DKD.This effect is likely mediated by the down-regulation of Ajuba,reduction of YAP1 expression,and subse-quent inhibition of ECM deposition.

Objective:To investigate the predictive value of early thyroid function changes on the efficacy of patients with Graves′ disease (GD) after 131I therapy. Methods:Data of patients with GD (59 males, 214 females; age (37.4±11.4) years) who underwent single therapy of 131I in Tianjin Medical University General Hospital from November 2017 to January 2019 were retrospectively analyzed. Symptoms, signs and laboratory tests (serum free triiodothyronine (FT 3) and serum free thyroxine (FT 4)) of patients were observed to assess the efficacy of 131I treatment. Efficacy was divided into complete remission (CR), partial remission (PR), non-remission (NR) or relapse. The changes of thyroid function (ΔFT 3=FT 3 before treatment-FT 3 after treatment)/FT 3 before treatment×100%; ΔFT 4=FT 4 before treatment-FT 4 after treatment)/FT 4 before treatment×100%) 1 month after 131I therapy in each efficacy group and differences among them were compared by using independent-sample t test, χ2 test, one-way analysis of variance and the least significant difference t test. ROC curves were drawn to analyze the predictive values of early thyroid function changes on the efficacy of 131I treatment for GD. Logistic regression analyses were performed to identify the influencing factors for the efficacy of 131I therapy. Results:CR rate and total effective rate of 273 GD patients after single therapy of 131I were 67.03%(183/273) and 92.67%(253/273), respectively. After 1 month, CR rate of euthyroidism group ( n=95) was significantly higher than that of hyperthyroidism group ( n=178; 81.05%(77/95) vs 59.55%(106/178); χ2=4.60, P=0.032). ΔFT 3 and ΔFT 4 at the first month were statistically significant and decreased sequentially in the CR group ( n=183), PR group ( n=70), NR or relapse groups ( n=20; F values: 15.40, 12.54, both P<0.001). ROC curve analysis showed that patients with ΔFT 3≥73.64% and (or) ΔFT 4≥59.03% had a higher probability of achieving CR, with sensitivities of 84.3% and 86.7%, and specificities of 62.6% and 62.6%, respectively. Logistic regression analysis showed that 24 h radioactive iodine uptake (odds ratio ( OR)=1.095, 95% CI: 1.031-1.139), dose of 131I given per gram of thyroid tissue ( OR=1.562, 95% CI: 1.321-1.694), ΔFT 3 ( OR=1.354, 95% CI: 1.295-1.482), ΔFT 4 ( OR=1.498, 95% CI: 1.384-1.608) were factors affecting the outcome of patients with GD treated with 131I treatment (all P<0.05). Conclusion:Effects of 131I treatment can be predicted based on the change of the thyroid function at the first month after 131I treatment in patients with GD.

Objective:To analyze the clinical outcomes of initial radioactive iodine 131I therapy (RIT) for patients with familial differentiated thyroid cancer (FDTC) and sporadic differentiated thyroid cancer (SDTC), along with their influencing factors. Methods:The clinical data of 120 FDTC and 480 SDTC patients who received RIT at the Department of Nuclear Medicine, Tianjin Medical University General Hospital from January 2016 to January 2022 were retrospectively analyzed. These patients, categorized into the FDTC and SDTC groups, were further divided into three subgroups based on their response to initial RIT: no evidence of disease (NED), biochemical persistence of disease (BPD), or structural/functional persistence of disease (S/FPD). For the NED subgroup, the disease-free survival (DFS) was analyzed. For the BPD and S/FPD subgroups, the progression-free survival (PFS) was investigated. Furthermore, risk factors for failure to reach the NED status were identified.Results:After initial RIT, 56 (46.7%), 50 (41.7%), 14 (11.6%) patients in the FDTC group reached the NED, BPD, and S/FPD statuses, respectively, while 284 (59.1%), 160 (33.3%), 36 (7.5%) and SDTC patients in the SDTC group were in the NED, BPD, and S/FPD statuses, respectively ( χ2 = 10.10, P = 0.013). The last follow-up revealed that 71 (59.1%), 36 (30.1%), 13 (10.8%) patients in the FDTC group were in the NED, BPD and S/FPD statuses, respectively, while 337 (70.2%), 114 (23.7%), 29 (6.1%) patients in the SDTC group reached the NED, BPD and S/FPD statuses, respectively ( χ2 = 8.99, P = 0.026). The F-NED and S-NED subgroups exhibited 5-year DFS rates of 92.4% and 97.4%, respectively, the F-BPD and S-BPD subgroups displayed 5-year PFS rates of 88.3% and 90.8%, respectively, while the F-S/FPD and S-S/FPD subgroups yielded in 5-year PFS rates of 78.2% and 79.6%, respectively. Univariate binary logistic regression analysis indicated that the maximum diameter of tumors, T stage, M stage, recurrence risk stratification, and postoperative stimulated thyroglobulin (p-sTg) were correlated with the achievement of the NED status ( χ2=6.37-13.10, P < 0.05). Multivariable binary logistic regression analysis showed that T stage and p-sTg were independent risk factors in the achievement of the NED status ( χ2=0.11-11.33, P < 0.05). Conclusions:The response to initial RIT assists in guiding the development of subsequent treatment and follow-up strategies for DTC patients. Given that the SDTC patients exhibited better outcomes than the FDTC patients, more alertness should be paid to the RIT for FDTC patients. For patients with higher p-sTg and T stage, the initial RIT dose and follow-up interval should be increased and reduced respectively as appropriate.

Objective:To explore the role and molecular mechanism of Shikonin(SKN) in inhibiting the growth of anaplastic thyroid carcinoma(ATC) cells.Methods:The effect of SKN on ferroptosis in ATC cell lines CAL-62 was detected by flow cytometry; the expression levels of NF-κB, ferroptosis-related genes glutathione peroxidase 4(GPX4) and selenoprotein thioredoxin reductase 1(TXNRD1), glucose metabolism-related genes pyruvate kinase isoform 2(PKM2) and glucose transporter protein 1(GLUT1) were detected by Western blotting; real-time fluorescence quantitative(qPCR) to detect changes in the expression levels of GPX4, PKM2 and GLUT1; reactive oxygen species(ROS) fluorescent probe to detect changes in intracellular ROS positivity; glucose and lactic acid assay kit to detect the levels of glucose, the raw material of glucose metabolism(GLU), and lactate(LD), the product of glucose metabolism; and establishment of a subcutaneous tumour model in BALB/c nude mice to analyse the inhibitory effect of SKN on ATC in vivo.Results:Compared to the control group, after SKN treatment, the protein expression levels of NF-κB, GPX4, TXNRD1, GLUT1, and PKM2 in CAL-62 cells decreased( P=0.004, P=0.012, P=0.043, P=0.001, P=0.018); the mRNA expression of GPX4, GLUT1, and PKM2 also decreased( P<0.001, P=0.029, P<0.001). Additionally, ROS production increased( P=0.041). After treatment with the ferroptosis inhibitor Liproxstatin-1(L-1), the proportion of cell death was reversed to a certain extent, and there was no statistically significant difference in cell death proportion after L-1 treatment. Intracellular ferroptosis occurred( P<0.001), with reduced levels of glutamate(GLU) uptake and lipid peroxidation(LD) generation( P<0.001). SKN inhibited ATC tumor growth in vivo( P=0.016). Conclusion:SKN promotes intracellular ferroptosis in ATC cells, inhibits glycolysis and glucose uptake, and suppresses ATC cell growth.

Objective:To investigate the mechanism of benzyl isothiocyanate(BITC) in the treatment of anaplastic thyroid cancer(ATC).Methods:Using network pharmacological analysis, key targets of BITC and ATC were screened, followed by GO and KEGG enrichment analysis. In order to validate the findings, AutoDock software was used to dock BITC and ATC key targets. BITC was applied to two ATC cell lines(8505C and CAL-62). Flow cytometry was used to analyze cell apoptosis. Autophagy inhibitors hydroxychloroquine sulfate(HCQ) and 3-methyladenine(3MA) were used in combination with BITC. Real-time quantitative PCR was conducted to detect the gene level of LC3B, while Western blotting was utilized to examine the expression of NF-κB, LC3B Ⅱ, Beclin-1, and Bcl-2. In animal experiments, a mouse tumor model was constructed using CAL-62 cells, treated with intraperitoneal injections of BITC(100 mg/kg) and normal saline respectively, administered every other day for a total of 21 days. Immunoblotting of tumor tissue was performed to detect the expression of LC3B Ⅱ, Bcl-2, Beclin-1, and NF-κB.Results:A total of 10 key targets with binding energies≤-4.0 kcal/mol were identified. KEGG analysis showed that these genes are mainly involved in NF-κB signaling pathway and apoptosis. BITC inhibited ATC cells with IC50 values of 27.56 μmol/L for 8505C and 28.30 μmol/L for CAL-62. The expression levels of NF-κB, Beclin-1, and Bcl-2 decreased, while LC3B Ⅱ and LC3B gene expression increased. Combining 3MA with BITC enhanced cell inhibition LC3B Ⅱ expression. HCQ increased LC3B Ⅱ expression without enhancing cell and viability inhibition. In the mouse tumor model, compared to the control group, the treatment group had higher LC3B Ⅱ and lower Bcl-2, Beclin-1, and NF-κB levels.Conclusion:BITC could inhibit the growth of ATC cells in vitro and in vivo, disrupt the autophagy degradation, and inhibit the NF-κB pathway.
