Objective: The purpose of this study was to investigate the associations between CYP3A4*18B and CYP3A5*3 polymorphism and cyclosporine-related liver injuries in Chinese renal transplant recipients. Methods: We genotyped 339 renal transplant recipients treated with a triple immunosuppressive regimen including cyclosporine for CYP3A4*18B and CYP3A5*3 polymorphism using the polymerase chain reaction restriction fragment length polymorphism assay. Results: The incidence of liver injury in the study population was 36.9% (125/339). At 1 month after transplantation, the trough concentration of cyclosporine (C0) in the group with CYP3A4*1/*1(GG alleles) was significantly higher than in the group with CYP3A4*18B/*1 8B(AA alleles) (p < 0.05). At 3 months after transplantation, the C0 in the group with CYP3A4*1/*1 and group with CYP3A4*1/*18B was markedly higher than in the group with CYP3A4*18B/*18B (p < 0.05). The GG genotypes of CYP3A4*18B were more common in the liver injury group compared with the control group (p < 0.05). Univariate logistic regression analysis showed that subjects carrying the GG genotypes had a 5.136- and 2.528-fold higher risk of developing cyclosporine-related liver injury than those with the AA and GA genotypes. When adjusted for sex, the risk of the CYP3A4*18B genotypes was OR = 4.969 for GG compared to AA (p = 0.030), and OR = 2.634 for GG compared to GA (p = 0.025). However, no association was observed between CYP3A5*3 polymorphisms with cyclosporine-related liver injury. Conclusions: These results suggested that the wild type of CYP3A4*18B is a risk factor for the development of cyclosporine- related liver injuries in Chinese renal transplant recipients.Correspondence to:

Aim: Neuropathic pain responds poorly to drug treatments. Partial relief is achieved in only about half of the patients. Danggui Sini decoction (DSD), an aqueous extract of Angelica sinensis, Ramulus Cinnamomi, and Radix Puerariae, has been used extensively in China to treat inflammatory and ischemic diseases. The current study examined the putative effects of DSD on neuropathic pain. Method: We used two commonly-used animal models: chronic constriction injury (CCI) and diabetic neuropathy for the study. And we examined effects of DSD on pain response, activation of microglia and astroglia in spinal dorsal horn, and expression of proinflammatory cytokines in the spinal cord. Results: Consecutive intragastric administration of DSD (25 – 100 mg/kg) for 10 days inhibited the mechanical and thermal nociceptive response induced by CCI and diabetes without interfering with the normal pain response. Meanwhile, in both models, DSD inhibited the over-expression of specific markers for microglia (Iba-1) and astroglia (GFAP) activation in the spinal dorsal horn. DSD also reduced the elevated nuclear NF-κB level and inhibited the up-regulation of proinflammatory cytokines, such as IL-6, IL-1β, and TNF-α, in the spinal cord. Conclusion: DSD can alleviate CCI and diabetes-induced neuropathic pain, and its effectiveness might be due to the inhibition of neuroinflammation in the spinal dorsal horn. The anti-inflammation effect of DSD may be related to the suppression of spinal NF-κB activation and/or cytokines expression. Correspondence to:

Aims: To evaluate the progression of transplant renal vein stenosis (TRVS) in the early post-operative period and its impact on clinical outcomes.
Materials and methods: This prospective study enrolled 23 consecutive patients with TRVS detected by contrast-enhanced ultrasound (CEUS). Duplex ultrasound (DUS) was performed on days 1, 30, and 90 after transplantation. The DUS measurements included peak velocity (PV) of stenosis and peak velocity ratio of stenosis to pre-stenosis (PV-ratio). The differences in DUS measurements across different timepoints were evaluated by linear mixed-effects model.
Results: The mean serum creatinine (SCr) levels at days 30 and 90 were 131 (range, 46 – 196) μmol/L, and 103 (range, 70 – 136) μmol/L, respectively. Two TRVS cases were caused by mural thrombi, the remaining 21 cases were free of any surgical complications. The mean TRVS-PV at days 1, 30, and 90 were 335 ± 92, 221 ± 86, and 134 ± 59 cm/s, respectively. The mean PV-ratio at days 1, 30, and 90 were 9.3 ± 5.0, 3.5 ± 1.9, and 2.0 ± 1.3, respectively. Linear mixed-effects model revealed a significant main effect of timepoint on SCr, TRVS-PV, and PV-ratio (p < 0.01 for all), exhibiting a gradually declining trend. There was no significant main effect of timepoint on arterial parameters.
Conclusion: TRVS unrelated to thrombotic causes in the early post-operative period is a transient finding not correlating with short-term outcome.Correspondence to:
