In situ bioimaging is a powerful tool for directly observing the localization, expression, and interactions of nucleic acids or protein targets within cells, providing essential insights into cell function and disease mechanisms. In recent years, the CRISPR/Cas9 system, a revolutionary gene-editing tool, has been applied to develop efficient in situ imaging techniques. This paper reviews recent CRISPR/Cas9-based imaging methods utilizing Cas9 protein, engineered single-guide RNA (sgRNA), and coupled fluorescent tags, and compares their application in living and fixed cells. It focuses on the specificity, signal amplification efficiency, and multi-modal imaging capabilities of these methods, with further discussion based on current research, aiming to offer a comprehensive overview of CRISPR/Cas9-based in situ bioimaging techniques, with some valuable reference and guidance for research in related fields.

Objective:To evaluate the clinical efficacy and safety of sulodexide soft capsules in treating proteinuria after renal transplantation, as well as its impact on graft function.Methods:The clinical data from 80 recipients who developed proteinuria after renal transplantation and were treated with sulodexide soft capsules during regular follow-up at the outpatient department of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from March 1, 2019, to March 1, 2023, were retrospectively analyzed. Proteinuria levels, graft function, safety-related indicators (coagulation function), and adverse events were compared before treatment and at 1, 2, 3, 6, and 12 months after treatment. Based on efficacy, recipients were divided into a satisfactory efficacy group (67 cases) and a general efficacy group (13 cases). Univariate and multivariate logistic regression analyses were conducted to stratify baseline data and explore factors influencing efficacy.Results:Among the 80 recipients, 63 (78.75%) had mild proteinuria and 17 (21.25%) had moderate proteinuria. The overall treatment response rate was 91.25% (73/80). Drug-related adverse events occurred in 12 patients (15.0%). Median urinary protein excretion at 1, 2, 3, 6, and 12 months post-treatment was 0.35 (0.20, 0.55) g/24 h, 0.30 (0.17, 0.44) g/24 h, 0.23 (0.15, 0.39) g/24 h, 0.21 (0.13, 0.32) g/24 h, and 0.15 (0.10, 0.23) g/24 h, respectively, all significantly lower than the pre-treatment level of 0.52 (0.43, 0.90) g/24 h (all P<0.001). The median urinary albumin-to-creatinine ratios at the corresponding time points were 99.15 (45.33, 201.13) μg/mg, 77.20 (43.30, 176.20) μg/mg, 57.50 (31.35, 173.75) μg/mg, 53.55 (25.90, 142.00) μg/mg, and 39.05 (20.53, 103.60) μg/mg, also significantly reduced compared to the pre-treatment value of 152.05 (71.90, 271.23) μg/mg ( P=0.012, P=0.003, P<0.001, P<0.001, P<0.001, respectively). At 12 months post-treatment, the serum creatinine level (132.86±36.86 μmol/L) showed a statistically significant improvement compared to the pre-treatment level (146.60±48.42 μmol/L) ( P=0.045). Univariate analysis indicated that satisfactory efficacy was associated with the time of proteinuria onset post-transplantation, the interval between proteinuria onset and treatment initiation, and recipient age ( HR= 1.001, 95% CI: 1.001-1.020, P=0.043; HR = 1.034, 95% CI: 1.009-1.058, P=0.006; HR=1.058, 95% CI: 1.003-1.116, P=0.040). Stratified univariate analysis revealed that proteinuria onset within 2 years post-transplantation, treatment initiation within 2 years of proteinuria onset, and age younger than 45 years were significantly associated with satisfactory efficacy ( HR=5.524, 95% CI: 1.510-20.207, P=0.010; HR= 7.800, 95% CI: 2.104-28.920, P=0.002; HR=5.972, 95% CI: 1.497-23.822, P=0.011). Multivariate analysis identified the interval between proteinuria onset and treatment initiation as an independent factor influencing satisfactory efficacy ( HR=1.025, 95% CI: 1.010-1.093, P=0.015). Conclusions:Sulodexide effectively reduces proteinuria after renal transplantation, particularly in mild-to-moderate or early-onset cases, while maintaining stable allograft function without significant adverse effects

Abstract: Bruton’s tyrosine kinase (BTK), a cytoplasmic tyrosine kinase, plays a central role in the activation of B cells and granulocytes, operating downstream of B cell and Fcγ receptors, and is considered an attractive target for treating autoimmune diseases. Preclinical investigations have demonstrated that inhibition of BTK activity holds promise as a potential therapeutic strategy for inflammatory immune responses such as autoimmune diseases and allergies. This review provides an overview of the mechanisms by which BTK contributes to immune-related diseases and summarizes current research on the development of BTK inhibitors for treating these conditions, aiming to offer novel insights into non-oncology applications for BTK inhibitors.

Objective:We employ different regimens of induction therapy in living donor ABO-incompatible kidney transplantation(ABOi-KT) recipients to compare their clinical outcomes during 6 months post-KT.Methods:A retrospective analysis was conducted for the relevant clinical data of 41 ABOi-KT recipients from June 2018 to September 2022.Thirteen recipients on induction therapy of anti-human T lymphocyte porcine immunoglobin(pATG)were enrolled in pATG group; 19 recipients on induction therapy of basiliximab in basiliximab group; 9 recipients on induction therapy of rabbit anti-human thymocyte immunoglobulin(rATG)in rATG group.Differences in age, gender, body mass index(BMI), dialysis modality/duration, sideness of donor kidney, frequency of blood group antibody treatment, dose of rituximab, basic blood group antibody titers of IgG/IgM, and the gender and BMI of recipient's donor were compared for three groups.Immune status was assessed by comparing absolute lymphocyte count before pre-treatment and within 6 months post-KT in recipients under different induction regimens among 3 groups by one-way analysis of variance.Transplant kidney function was assessed by comparing the levels of serum creatinine, estimated glomerular filtration rate(eGFR)and serum urea nitrogen using one-way analysis of variance.The incidence of delayed graft function(DGF), acute rejection(AR)and infection was compared among three groups.Results:Regarding baseline profiles, except for donor age pATG group[(60.23±6.10)years]versus basiliximab group[(51.95±6.97)years]was statistically significant( P=0.002), the differences in the remaining parameters were not statistically significant among three groups(all P>0.05). At Day 1/3/7/10/14 post-KT, absolute lymphocyte counts were(0.17±0.07)×10 9/L, (0.27±0.14)×10 9/L, (0.85±0.40)×10 9/L, (1.05±0.56)×10 9/L and(1.10±0.56)×10 9/L in pATG group and(0.69±0.04)×10 9/L, (0.18±0.21)×10 9/L, (0.57±0.44)×10 9/L, (0.67±0.45)×10 9/L and(0.81±0.46)×10 9/L in rATG group respectively.They were all higher than those in basiliximab group[(0.46±0.18)×10 9/L, (0.67±0.26)×10 9/L, (1.29±0.48)×10 9/L, (1.56±0.49)×10 9/L, (1.75±0.53)×10 9/L]and the differences were statistically significant(all P<0.05). No statistically significant difference existed in absolute lymphocyte count among 3 groups before pre-treatment and after Day 21 post-KT(all P>0.05). At Week 1/2/4/12/24 post-KT, the differences in serum levels of creatinine and urea nitrogen were not statistically significant( P>0.05). At Month 1/3 post-KT, eGFR was(47.24±14.51)and(49.94±14.31)ml·min -1·(1.73 2) -1 in rATG group and they were lower than(67.36±21.60)and(65.00±14.67)ml·min -1·(1.73 2) -1 in basiliximab group with a statistically significant difference( P<0.05). However, at Week 1/2/24 post-KT, no statistically significant difference existed in eGFR among 3 groups( P>0.05). In ATG, basiliximab and rATG groups, DGF(1 case, 1 case, 1 case), AR(2 cases, 2 cases, 1 case)and infection(4 cases, 7 cases, 3 cases)occurred during 6 months post-KT. Conclusions:Through a limited sample of single centers, no statistically significant difference existed in graft function recovery for ABOi-KT recipients on induction therapies of pATG, basiliximab and rATG.And DGF, AR and infections occurred in all three groups.However, there were little inter-group differences.
