Objective To study the relationship between rs290487,rs7903146 of transcription factor 7-Like 2 (TCF7L2) gene and post-transplantation diabetes mellitus in Han Zhejiang population.Method We genotyped two single nucleotide polymorphisms (SNPs) across the TCF7L2 gene in 90 unrelated post-transplantation type 2 diabetes mellitus (PTDM) patients,112 unrelated non-PTDM patients,and a set of post-transplantation diabetes mellitus patients (n =68).Genotyping was performed using direct sequencing SNP Genotyping Assays.The association of SNPs with post-transplantation diabetes mellitus was analyzed.Result In this study,there was statistically significant difference in the T-allele of TCF7L2.rs7903146 between PTDM group (5.1％) and non-PTDM group (1.3％) (P＜0.05).For rs7903146,the frequencies of genotype C/C,C/T (70.0％) and T/T (35.8％) was statistically significant in PTDM group (P＜0.05).For rs290487,the frequencies of genotype C/C,C/T and T/T was 14.7％,38.2％ and 47.1％ respectively in PTDM group,P＞ 0.05.The incidence of PTDM was significantly higher in patients with the CT genotype (odds ratio 18.54 [95％ CI 1.21-282.26],P =0.03).Conclusion With the current sample size,we found that the CT genotype of rs7903146 was significantly associated with post-transplantation diabetes mellitus.

ObjectiveTo explore the efficacy and safety of percutaneous antegrade stenting in the treatment of ureteral obstruction after renal transplantation.MethodsWe retrospectively reviewed 11patients with renal graft ureteral obstruction (2 cases of acute obstruction and 9 cases of chronic obstruction) from March 2009 to March 2011.The etiology of the obstruction was renal graft-ureter-bladder anastomotic stricture in 5 cases,stone obstruction in 2 cases,and undetermined in 4 cases.Renal graft and collecting system were examined by ultrasonography preoperatively to select suitable puncture position,and then ureteropyelography was performed under X-ray guidance.When the obstruction location was clear,the urology guidewire was implanted to the bladder by needle,and then guidewire was released by cystoscopy.Ureteral stent was implanted along the guidewire,and upper ureteral stents was observed under X-ray. After removal of guidewire,the stent location was confirmed once again.The renal pelvis fistula drainage lasted for 1-2 weeks,and ureteral stent to 6 months to one year.Ultrasound and renal function were tested after 1week,1month,3 months and 6 months,and then every six months.ResultsOperation was done successfully in 10 patients,and failed in one case due to a long segment of ureteral stenosis.The operating time of ureteral stent implantation was 54±27 min.Serum creatinine of patients was reduced from preoperative 326±147 to postoperative 89±49 μmol/L.During a follow-up period of 6 to 27 months,no complications occurred.ConclusionPercutaneous antegrade stenting in the treatment of ureteral obstruction after renal transplantation is safe and effective.

Objective To explore the correlation between post-transplant glomerular filtration rate (GFR) in 1 year and long-term graft survival in renal transplant patients.Methods The clinical data of 334 patients who received their cadaveric kidney transplantations between November 1994 and October 2004 were analyzed retrospectively.According to the GFR at one year after transplant operation, normal GFR group was defined as GFR more than or equal to 1.083 ml/s, while patients whose GFR less than 1.083 ml/s were fallen into abnormal GFR group.Cockeroft-Gault (C-G) formula was used to compare the difference in the renal function between the two groups.Kaplan-Meier assay was used to compare the difference in the allograft survival between the two groups in the functional renal allograft or the non-functional renal allograft.The correlativity of GFR level at the first year and the GFR level at the 5th year was analyzed.Results The GFR level at the first year after transplantation was proportional to the graft survival time of the kidney.Five and ten years after transplantation, the renal transplantation long-term survival rate in the normal renal function groups was significantly higher than in the abnormal renal function groups (P＜0.05).As compared with the GFR level at the first year after transplantation, the changes in amplitude of GFR level at the 5th year after transplantation was (0.080 ±0.248) ml/s, and the descent had a positive correlation with GFR level at the 5th year after transplantatioa Conclusion GFR level at the first year after transplantation predicts long-term renal functioa The higher of GFR level at the first year, the higher of GFR level at the 5th year.

Objective:To investigate the expressions and clinical significances of histone marks H3K9me3 and H3K27me3 in colorectal cancer.Methods:A retrospective case-control study was conducted. The clinical data of 98 patients with colorectal cancer in Shanxi Province Cancer Hospital from May 2008 to July 2017 were retrospectively analyzed, including 35 patients in the non-metastatic operation-only group, 29 patients in the synchronous hepatic oligometastasis group and 34 patients in the extensive metastasis group, and 33 patients with benign colorectal lesions who underwent colonoscopy in 2017 were selected as the control group. Immunohistochemical assay was used to detect the expressions of H3K9me3 and H3K27me3 proteins in each group, and the expressions of H3K9me3 and H3K27me3 proteins in colorectal cancer patients with different clinicopathological features were analyzed. Kaplan-Meier method was used for survival analysis and log-rank test was performed.Results:The positive expression rate of H3K9me3 protein in colorectal cancer group was 11.2% (11/98), which was lower than that in control group [60.6% (22/33)] ( χ2 = 33.33, P < 0.001); the positive expression rate of H3K27me3 protein in colorectal cancer group was 10.6% (13/98), which was lower than that in control group [97.0% (32/33)] ( χ2 = 76.70, P < 0.001). The positive expression rates of H3K9me3 protein were 60.6% (20/33), 17.1% (6/35), 10.3% (3/29) and 5.9 % (2/34) in the control group, the non-metastatic operation-only group, the synchronous hepatic oligometastasis group and the extensive metastasis group, respectively, and the difference was statistically significant ( χ2 = 26.10, P < 0.001); the positive expression rates of H3K27me3 protein were 97.0% (32/33), 14.3% (5/35), 20.7% (6/29) and 5.9% (2/34), respectively, and the difference was statistically significant ( χ2 = 44.16, P < 0.001). The positive expression rate of H3K27me3 in colorectal cancer tissues of patients with lymph node metastasis degree ≤0.2 was higher than that of patients with lymph node metastasis degree >0.2 [22.4% (11/49) vs. 4.2% (2/48), χ2 = 6.98, P = 0.008]. The median overall survival (OS) time of H3K9me3 positive and negative colorectal cancer patients was 77.0 months (95% CI: 10.6-143.3 months) and 34.0 months (95% CI: 25.5-42.5 months), respectively, and there was no significant difference in OS between the two groups ( P = 0.078). The median OS time of H3K27me3 positive and negative colorectal cancer patients was 39.0 months (95% CI: 15.3- 62.7 months) and 34.0 months (95% CI: 24.3-43.7 months), respectively, and there was no significant difference in OS between the two groups ( P = 0.524). Conclusions:The expressions of H3K9me3 and H3K27me3 in colorectal cancer tissues are lower than those in colorectal benign lesions, and gradually decrease with occurrence of liver metastasis and extensive metastasis. H3K9me3 and H3K27me3 may be potential cancer suppressor factors.

Nanomaterial-based drug sustainable release systems have been tentatively applied to bone regeneration. They, however, still face disadvantages of high toxicity, low biocompatibility, and low drug-load capacity. In view of the low toxicity and high biocompatibility of polymer nanomaterials and the excellent load capacity of hollow nanomaterials with high specific surface area, we evaluated the hollow polydopamine nanoparticles (HPDA NPs), in order to find an optimal system to effectively deliver the osteogenic drugs to improve treatment of bone defect. Data demonstrated that the HPDA NPs synthesized herein could efficiently load four types of osteogenic drugs and the drugs can effectively release from the HPDA NPs for a relatively longer time in vitro and in vivo with low toxicity and high biocompatibility. Results of qRT-PCR, ALP, and alizarin red S staining showed that drugs released from the HPDA NPs could promote osteogenic differentiation and proliferation of rat bone marrow mesenchymal stem cells (rBMSCs) in vitro. Image data from micro-CT and H&E staining showed that all four osteogenic drugs released from the HPDA NPs effectively promoted bone regeneration in the defect of tooth extraction fossa in vivo, especially tacrolimus. These results suggest that the HPDA NPs, the biodegradable hollow polymer nanoparticles with high drug load rate and sustainable release ability, have good prospect to treat the bone defect in future clinical practice.
