Effects of Wuzhi capsules on tacrolimus concentration in renal transplant recipients with different CYP3A5 genotypes / 中华泌尿外科杂志

Objective:To study the effect of Wuzhi capsules on tacrolimus trough concentration in kidney transplant recipients with different CYP3A5 genotypes.Methods:From June 2015 to October 2019, 162 patients who underwent renal transplantation for the first time were retrospectively analyzed. The patients were divided into two groups, combined and uncombined, according to whether combined with Wuzhi capsules. There were 81 cases in the uncombined group (55 males and 26 females), and 81 in the combined group (62 males and 19 females). There was no significant difference between the two groups( P=0.219). The ages of the uncombined group and the combined group were (39.26±11.91) years old and (37.21±10.88) years old ( P=0.103), the weights were (62.39±11.64) kg and (66.18±13.89)kg ( P=0.298), systolic blood pressure were (147.28±20.24) mmHg and (145.00±16.42) mmHg (1 mmHg=0.133 kPa)( P=0.276), diastolic blood pressure were (92.25±13.87) mmHg and (92.20±12.53) mmHg ( P=0.886), alanine aminotransferase were (12.24±8.59) U/L and (17.06±13.11) U/L ( P=0.015), aspartate aminotransferase were (17.76±9.12) U/L and (16.57±8.37) U/L ( P=0.463), fasting blood glucose were (8.70±3.48) mmol/L and (7.18±2.74)mmol/L ( P=0.006), hemoglobin were (98.96±17.53) g/L and (101.05±18.67) g/L ( P=0.789), creatinine were (665.22±296.55) μmol/L and (797.32±279.32) μmol/L ( P=0.007), estimated glomerular filtration rate were (11.47±14.11) ml/(min·1.73m 2) and (8.85±3.71) ml/(min·1.73m 2) ( P=0.130)in the kidney transplant recipients before surgery. Among the 162 cases in this study, there were 86 cases (53.09%) of CYP3A5*1*3 genotype, 17 cases (10.49%) of CYP3A5*1*1 genotype, 59 cases (36.42%) of CYP3A5*3*3 genotype, and the minimum allele frequency of CYP3A5*1 was 37.04%. In the uncombined group, CYP3A5*1*3 genotype 39 cases (48.15%), CYP3A5*1*1 genotype 5 cases (6.17%), and CYP3A5*3*3 genotype 37 cases (45.68%). In the combined group, CYP3A5*1*3 genotype 47 cases (58.02%), CYP3A5*1*1 genotype 12 cases (14.81%), and CYP3A5*3*3 genotype 22 cases (27.16%), with statistically significant differences in the two groups ( P=0.024). The patients were treated with a triple immunosuppressive regimen (tacrolimus+ mycophenolate mofetil+ glucocorticoid) based on tacrolimus [initial dose: 0.15-0.30 mg/(kg·d)], combination of Wuzhi capsules in the combination group (11.25 mg, twice a day). The trough concentration of tacrolimus was detected by enzyme-linked immunosorbent assay, compare the difference in the trough concentration of tacrolimus between the two groups. The relationship between the effect of Wuzhi capsules and CYP3A5 gene polymorphism was compared, and compare the changes before and after the application of CYP3A5 genotype combined with Wuzhi Capsules. The influencing factors of tacrolimus trough concentration were analyzed by multiple linear regression. Results:In the combined with Wuzhi capsules, the dose corrected trough concentration (C 0/D) of tacrolimus was higher than that in patients without Wuzhi capsules, and the extent of increase was related to genotype. The C 0/D of tacrolimus in patients with CYP3A5*3*3 genotype in the combination and non-combination groups were (12.15±2.95) (ng·ml -1/0.1mg·kg -1·d -1) and (9.99±2.33) (ng·ml -1/0.1mg·kg -1·d -1) ( P=0.004), CYP3A5*1*3 genotype were (11.11±3.20) (ng·ml -1/0.1mg·kg -1·d -1) and (6.86±1.62) (ng·ml -1/0.1mg·kg -1·d -1) ( P<0.001), and there were significant difference. However, CYP3A5*1*1 genotype were(8.29±2.64) (ng·ml -1/0.1mg·kg -1·d -1) and (6.16±2.87) (ng·ml -1/0.1mg·kg -1·d -1) ( P=0.160), there was no significant difference. The tacrolimus C 0/D of the combined group before and after the Wuzhi capsule were as follows: CYP3A5*3*3 genotype: (7.18±2.33)(ng·ml -1/0.1mg·kg -1·d -1) and (13.33±3.09) (ng·ml -1/0.1mg·kg -1·d -1) ( P<0.001); CYP3A5*1*3 genotype: (5.14±2.14) (ng·ml -1/0.1mg·kg -1·d -1) and (10.61±3.20) (ng·ml -1/0.1mg·kg -1·d -1) ( P<0.001); CYP3A5*1*1 genotype: (5.17±3.75) (ng·ml -1/0.1mg·kg -1·d -1) and (8.31±2.74) (ng·ml -1/0.1mg·kg -1·d -1)( P=0.002), and the differences were statistically significant. The results of multiple linear regression showed that the combination of Wuzhi capsules (β=0.508, P<0.001) and CYP3A5 genotype(CYP3A5*1*3 and CYP3A5*3*3: β=-0.361, P<0.001; CYP3A5*1*1 and CYP3A5*3*3: β=-0.425, P<0.001)could influence the trough concentration. The sex (β=-0.100, P=0.124) and age (β=-0.003, P=0.967) of renal transplant recipients had no statistical significance to tacrolimus C 0/D. Conclusions:In the renal transplant patients, CYP3A5 genotype and combined use of Wuzhi capsules are the main factors affecting tacrolimus C 0/D. In order to achieve the expected trough concentration as soon as possible, the interaction between CYP3A5 genotypes and drug combination should be considered.

Isolation and culture of adipose-derived mesenchymal stem cells from inbreed line miniature pig of Wuzhishan and their biological characteristics / 中南大学学报(医学版)

To establish a method for isolation, culture and identification of adipose-derived mesenchymal stem cells (ASCs) from the inbreed line miniature pig of Wuzhishan (ILMW).
 Methods: A total of 100 g adipose tissues were obtained from subcutaneous tissues of neck in six-month old healthy ILMW (3 samples, male). ASCs from ILMW (ILMW-ASCs) were isolated from adipose tissues through 0.1% collagenase digestion. The cells at the 3rd, 5th, 8th, 13th passages were collected. Cell morphology, size, phenotype, cell cycle, and apoptosis were monitored. Cell differentiation was induced and cell proliferation curve was drawn.
 Results: The ILMW-ASCs, fibroblast-like or whirlpool-like, began the adherence at 36 h and entered a logarithmic phase in the 5th day. Eighty percent of them were fused in the 7th day. The average diameter and volume of ILMW-ASCs were (17.00±0.54) µm and (2.58±0.24)×10-9 L, respectively. The expressions of CD29, CD44 and CD90 were positive, and there was no significant difference between the different passages (all P>0.05). The expressions of CD45, CD8a and HLA-DR were increased with the increase in passages after the 3th passage (all P<0.05). The adipogenic induction of ILMW-ASCs was observed by positive oil red O staining, and the osteogenic induction of ILMW-ASCs was determined by positive alizarin red staining. Apoptosis and senescence occurred in the 13 passage of ILMW-ASCs, and the proportion of S phase of cell cycle was lower than that in lower passages (all P<0.05). 
 Conclusion: ILMW-ASCs are one of the best choice for porcine ASCs, which might provide a source of candidate stem cells for therapy of large animal disease models and tissue or organ repairment.

Research progress in mechanisms for drug-resistance and recurrence in bladder cancer / 中南大学学报(医学版)

Bladder cancer is a common malignant tumor in the urinary system, and its drug-resistant recurrence has become a major problem in clinical treatment. At present, there is still a lack of molecular markers for effectively predicting bladder cancer resistance. The mechanisms for drug resistance in bladder cancer is very complicated. The common mechanisms of drug resistance include epigenetic modification, abnormal expression level, abnormal regulation of non-coding RNA, production of bladder cancer stem cells, increase of drug efflux and autophagy. The various drug resistance mechanisms of bladder cancer are not independent, but there is a certain relationship between them, which leads to the occurrence of drug resistance. Further study on the mechanisms for bladder cancer resistance is of great importance to overcome these problems.

To isolate bone marrow mesenchymal stem cells (BM-MSCs) and establish the model of chronic kidney disease (CKD) of Wuzhishan (WZS) mini-pig, and to study the repairment effect of BM-MSCs on CKD-induced renal fibrosis in vitro.
 Methods: Density gradient method was used to isolate and culture BM-MSCs. The cells were verified by morphology, phenotype, differentiation and so on. The left partial ureteral obstruction (LPUUO) was used to establish the CKD model, which was evaluated by B-ultrasound, single-photon emission computed tomography (SPECT), HE and Masson staining. The cells were divided into 3 groups, the tissue plus BM-MSCs group, the tissue group, and the BM-MSCs group, respectively. Seven days later, the supernatants were collected to observe the changes of hepatocyte growth factor (HGF) cumulative release. HE and Masson staining was used to observe the changes of renal tissue.
 Results: The isolated BM-MSCs possessed the features as follow: fibroblast-like adherent growth; positive in CD29 and CD90 expression while negative in CD45 expression; osteogenic induction and alizarin red staining were positive; alcian blue staining were positive after chondrogenic induction. Twelve weeks after the operation of LPUUO, B-ultrasound showed the thin renal cortical with pelvis effusion; SPETCT showed the left kidney delayed filling and renal impairment. The accumulation of HGF in the tissue plus BM-MSCs group was significantly higher than that in the tissue alone group at the 1st, 5th, 6th, 7th day, respectively (P<0.05). HE staining showed the different degree of renal lesions between the tissue plus BM-MSCs+CKD group and the tissue alone group, which was aggravated with the time going. Masson staining showed that the cumulative optical density of blue-stained collagen fibers in tissue plus BM-MSCs group was significantly lower than that in the tissue group at the 5th to 7th day (P<0.05).
 Conclusion: BM-MSCs from WZS mini-pig can inhibit or delay the progress of CKD-induced renal fibrosis through autocrine HGF in vitro.

Research status of Chinese medicine in diabetic nephropathy / 国际中医中药杂志

Diabetic nephropathy is one of the microvascular complications of type 2 diabetes mellitus. Recently, the modern medical researches and treatments of diabetic nephropathy have some progress, but the treatment delaying the progress of renal function is still unknown. Many clinical practices showed that the traditional Chinese medicine on this disease was effective. Thus, this paper was to summarize the traditional Chinese medicine view of etiology and pathogenesis, clinical researches, experimental researches in order provide reference for clinical treatment.

Study progress of traditional Chinese medicine treating type 2 diabetes macrovascular disease / 国际中医中药杂志

Type 2 diabetes macrovascular disease is the main cause of death in type 2 diabetes mellitus. In recent years, the modern medical research and treatment of type 2 diabetes macrovascular disease has made some progress, but the international clinical trials suggest that the current treatment can not effectively reduce the incidence of this disease. Many clinical practices show that the effect of traditional Chinese medicine on this disease is exact, so that the clinical workers on the treatment of type 2 diabetes mellitus macrovascular disease of the status quo, now from the etiology and pathogenesis,clinical research, experimental research on the literature published in recent years, to provide reference for clinical treatment.
