Inflammatory bowel disease (IBD) is a chronic, relapsing intestinal disorder driven by multiple factors including genetics, immunity, and environment, and is clinically classified into ulcerative colitis and Crohn's disease. Currently, mice and zebrafish are the primary experimental animals used in IBD research, among which zebrafish have emerged as an ideal model due to their unique advantages. Compared with rodent models, zebrafish serve as an effective and convenient model, offering advantages such as a short life cycle, robust reproductive capacity, small size, and transparent embryos. These characteristics make zebrafish highly suitable for dynamic tracking of continuous pathological progression and high-throughput drug screening. Zebrafish share over 70% genetic homology with humans, and their intestinal cellular composition and ontogeny closely resemble those of humans. Moreover, the structure and characteristics of their gut microbiota are similar to the human intestinal microbiome, providing a solid foundation for studying the relationship between gut microbiota and IBD. With advances in biotechnology, zebrafish IBD models generated by chemical induction or genetic engineering can accurately simulate the core pathological features of human IBD, such as intestinal wall thickening, inflammatory cell infiltration, and elevated expression of pro-inflammatory factors. These models have played a significant role in revealing the pathogenesis of IBD as well as the development of targeted therapeutic drugs. This article first outlines the intestinal characteristics of zebrafish and features of zebrafish IBD models, then provides an in-depth analysis of their application in IBD pathogenesis research from multiple aspects, including genetics, immunity, environment and diet, and infection. It also reviews research progress on the application of zebrafish in the development of anti-inflammatory drugs, probiotics, and traditional Chinese medicine therapies, aiming to provide researchers with references for the rational use of zebrafish models at all stages of preclinical research, to advance fundamental IBD research and accelerate breakthroughs in this field.

ObjectiveTo evaluate the clinical efficacy and safety of Baoshen prescription in the treatment of stage Ⅳ diabetic nephropathy （DN） in the patients with syndromes of Qi-Yin deficiency and kidney collateral stasis and obstruction， and to explore the mechanism of this prescription delaying the disease progression. MethodsA randomized， controlled， double-blind， multicenter clinical trial was conducted， in which 94 stage Ⅳ DN patients with syndromes of Qi-Yin deficiency and kidney collateral stasis and obstruction were randomly assigned into Baoshen prescription and control groups （47 cases）. The treatment lasted for 12 weeks. The primary efficacy indicators were mainly renal function indexes， including urine albumin-to-creatinine ratio （UACR）， 24-hour urine total protein （24 h-UTP）， serum creatinine （SCr）， and estimated glomerular filtration rate （eGFR）. The secondary efficacy indicators were metabolic memory of hyperglycemia， podocyte epithelial-to-mesenchymal transdifferentiation-related indexes， and TCM syndrome score. ResultsAfter 12 weeks of treatment， the Baoshen prescription group showed lowered levels of advanced glycation end products （lgAGEs）， connective tissue growth factor （CTGF）， type Ⅳ collagen （Col-Ⅳ）， receptor of AGEs （RAGE）， urinary fibroblast-specific protein-1 （FSP-1）， UACR， 24 h-UTP， and glycated hemoglobin （HbAlc） （P<0.05）， and an upward trend of miR-21 mRNA. The control group showed elevated levels of SCr and UREA and lowered levels of urinary FSP-1， eGFR， and HbAlc （P<0.05）. After treatment， the Baoshen prescription group had lower levels of lgAGEs， CTGF， urinary FSP-1， SCr， UACR， and 24 h-UTP and higher levels of Col-Ⅳ and eGFR than the control group （P<0.05）. In addition， the Baoshen prescription group showed statistically significant differences in SCr， eGFR， UACR， and 24 h-UTP before and after treatment （P<0.05）. ConclusionBaoshen prescription can effectively improve the renal function， reduce the urinary protein level， and alleviate clinical symptoms in stage Ⅳ DN patients with syndromes of Qi-Yin deficiency and kidney collateral stasis and obstruction. The mechanism may be related to the metabolic memory of hyperglycemia and epithelial-to-mesenchymal transdifferentiation of podocytes.

Objective To observe the effect of BaoShenTongLuo(BSTL)Decoction on diabetic kidney disease and serum inflammatory factors of DKD.Methods A total of 80 DKD patients were collected from patients of Beijing Hospital of Traditional Chinese Medicine.The patients were then randomly divided into control group and treatment group.Patients in control group were received with basic treatment.Patients in treatment group were received with BSTL decoction along with basic treatment.The treatments were lasted for 3 months.Scr,BUN,UACR,24 h proteinuria,MCP-1,TGF-β 1,CRP,IL-6 and TNF-a were detected.Clinical symptom scores of patients in two groups were calculated.Results The total effective rate of treatment group was higher than that in the control group(P<0.05).The scores of TCM symptoms were lower in the treatment group than those in the control group after treatment(P<0.01).Compared with control group,24 h proteinuria,UACR,Scr and BUN was significantly decreased in treatment group after the treatment(P<0.01).After the treatment,the level of MCP-1,TGF-β1,CRP,IL-6 and TNF-α were significantly decreased in treatment group compared with control group(P<0.01).Conclusion BSTL can significantly decrease proteinuria and improved renal function in DKD.More importantly,BSTL can significantly decrease serum inflammatory factors of DKD.

Objective:To explore the effect of decision-making aid intervention based on information shared decision-making tools in patients with lung cancer.Methods:From April 2019 to December 2020, convenience sampling was used to select 106 patients with lung cancer in the First Affiliated Hospital of Xinjiang Medical University as the research object. According to the random number table method, the patients were divided into the observation group and the control group, with 53 cases in each group. The control group conducted routine decision-making aid intervention, and the observation group added information shared decision-making tool intervention on the basis of the control group. The Decisional Conflict Scale (DCS) and the Patients Satisfaction with Participation in Medical Decision-making Scale were used to evaluate and compare the decision-making difficulty and participation satisfaction of the two groups of patients.Results:The DCS scores of observation group and control group after intervention were lower than those before intervention, and the difference was statistically significant ( P<0.05) . The DCS score of the observation group after intervention was lower than that of the control group, and the difference was statistically significant ( P<0.01) . The scores of all dimensions and total scores of the Patients Satisfaction with Participation in Medical Decision-making Scale of the observation group were higher than those of the control group, and the difference was statistically significant ( P<0.05) . Conclusions:Decision-making aid intervention can alleviate the patient's decision-making difficulty. Compared with conventional decision-making aids, cooperating with information shared decision-making tools has advantages in alleviating the difficulty of decision-making for patients with lung cancer and improving the satisfaction of decision-making participation.

Objective:Based on systematic idea of clustering methods, a novel approach for classifying prescriptions was explored in the light of the method of classifying analogous prescriptions.Methods:A total of 581 ancient prescriptions were selected from Treatment Record of Hundreds of Selected Ancient Prescriptions, and the standardized names of Traditional Chinese Medicines in these prescriptions were entered in Microsoft Excel 2007, then imported to SPSS 24.0 to generate dendrograms using the hierarchical clustering function. The classification of 581 selected ancient prescriptions was analyzed. Results:All 581 prescriptions could be classified into 86 categories through repeated clustering, the largest group has 29 prescriptions, the smallest group has 2 prescriptions, and the average group has about 6.75 prescriptions. In general, the later the intercepted group, the lower the similarity of its internal prescriptions.Conclusion:This method could realize the classification of prescriptions in the light of the method of classifying analogous prescriptions, which may help to break the original thinking bondage and further deepen the understanding of compatibility rules of prescriptions. However, its disadvantage lied in that the theoretical clues would be reduced when analyzing the compatibility rules of prescriptions and the issues of drug dosage, nature, taste and meridian categories were not specially considered.

Objective To evaluate the clinical effects of the treatment on chronic kidney disease 3 with dampness-heat type. Methods A retrospective cohort study recruited 103 patients with qi deficiency and dampness-heat type of CKD3. Among them,51 cases in the control group were treated with western medicine therapy. The 52 cases in the treatment group received Qingbudigui Decoction. SCr ,eGFR and 24hU-Prowere were observed after 12 months and 24 months for evaluating the clinical effects of Qingbudigui Decoction. Results After 12 and 24 months treatment,the treatment group had a significantly lower SCr and U-Pro(P < 0.01),but a higher eGFR (P<0.01,P<0.05). After 12 months and 24 months,there was no significant change in SCr,U-Pro or eGFR in the control group (P > 0.05). Conclusions Combination therapy of the Qingbudigui Decoction of the patients with qi deficiency and dampness-heat type of CKD3 could delay the kidney disease,which is superior to simple western medicine group. The mechanism may be related to the reduction of urinary protein excretion.

Purpose To investigate the prognostic value of whole-body magnetic resonance imaging (WB-MRI) for patients with multiple myeloma (MM).Materials and Methods Sixty-two newly diagnosed patients with MM confirmed by pathology during January 2010 and December 2016 were enrolled in this study.The patients were divided into five groups according to the infiltrative patterns on MRI:normal pattern,micro-nodular pattern,macronodular pattern,mixed pattern and diffuse pattern,and their overall survival were compared.Results Of all the patients,micro-nodular infiltrative pattern was found in 20 patients,macro-nodular pattern in 13 patients,mixed pattern in 7 patients and diffuse pattern in 17 patients,while 5 patients were normal.During the follow-up for a median of 39 months (ranged 30.9-47.1 months),overall survival with the mixed MM infiltrative pattern (median 17 months,95％ CI 12.6-21.3 months) was statistically shorter than those with other patterns (median 43 months,95％ CI 33.7-52.3 months;P＜0.05).Additionally,the clinical DurieSalmon (DS) and International Staging System (ISS) were applied to evaluate the stage of MM patients.DS system showed that 6 patients were at stage I,another 6 patients were at stage Ⅱ and the other 50 patients were at stage Ⅲ.While based on ISS system,15 patients were found at stage Ⅰ,22 patients were at stage Ⅱ and the rest 25 patients were at stage Ⅲ.Meanwhile,the correlation between the WB-MRI infiltrative pattems and DS system as well as ISS system had no significant correlation (P＞0.05).Conclusion Different infiltrative patterns in WB-MRI can predict the prognosis in patients with MM at the time of diagnosis.

Objective To explore the effect of recombinant human erythropoietin (rhEPO) on expression of brain-derived neurotrophic factor (BDNF) in different brain regions of aging rats. Methods Forty male SD rats were randomized equally into negative control group, D-galactose group, EPO treatment group, and positive control group. Rat models of subacute aging were established by continuous subcutaneous injection of 5%D-galactose. Immunohistochemical staining was used to analyze the variation of BDNF expressions in different brain regions of the aging rats with different treatments. Results Significant brain region-specific differences in BDNF expression were found among the rats in different groups. Compared with those in the negative control group, the numbers of BDNF-positive cells in the hippocampal CA1 region, CA3 region, dentate gyrus (DG) and frontal cortex were all decreased obviously in D-galactose group (P<0.05) but increased in both EPO group and the positive control group (P<0.05) without significant differences between the latter two groups. In the rats in the same group, the number of BDNF-positive cells varied markedly in different brain regions (P<0.05), and the expression level of BDNF was the highest in the frontal cortex followed by the hippocampal CA3 region and the dentate gyrus, and was the lowest in the hippocampal CA1 region. Conclusion Treatment with rhEPO enhances the expression of BDNF in rat neural cells, suggesting that rhEPO may protect the nervous system from aging by regulating the BDNF pathway.
