Abstract
Objective: To compare the application effect of the colonoscopy, fecal immunochemical test (FIT) and novel risk-adapted screening approach in colorectal cancer screening in Xuzhou population. Methods: From May 2018 to April 2019, 4 280 subjects aged 50-74 were recruited from Gulou district, Yunlong district and Quanshan district of Xuzhou. They were randomly assigned to the colonoscopy group (n=863), FIT group (n=1 723) and novel risk-adapted screening approach group (n=1 694) according to the ratio of 1∶2∶2. For the novel risk-adapted screening approach group, after the risk assessment, high-risk subjects were invited to undergo colonoscopy and low-risk subjects were invited to undergo FIT examination. All FIT positive subjects were invited to undergo colonoscopy. Colonoscopy participation rate [(the number of colonoscopies completed/the number of colonoscopies invited to participate)×100%], detection rate of colorectal lesions [(the number of diagnosed patients/the number of colonoscopies completed)×100%], colonoscopy resource load (the number of colonoscopies completed/the number of diagnosed advanced tumors) and FIT resource load in each group were calculated and compared. Results: The age of all subjects was (61±6) years old, including 1 816 males (42.43%). There was no statistically significant difference in the socio-demographic characteristics of the subjects in different screening groups. The colonoscopy participation rate was 22.60% (195/863) in the colonoscopy group, 57.04% (77/135) in the FIT group, and 33.94% (149/439) in the novel risk-adapted screening approach group, respectively. The colonoscopy participation rate was higher in the FIT group than in the colonoscopy group and the novel risk-adapted screening approach group (P<0.001). The colonoscopy participation rate of novel risk-adapted screening group was significantly higher than the colonoscopy group (P<0.001). The detection rates of advanced tumors were 6.67% (13/195), 9.09% (7/77) and 8.72% (13/149), respectively, and the difference was not statistically significant (P>0.05). The colonoscopy resource load (95%CI) was 15 (13-17) in the colonoscopy group, 11 (9-14) in the FIT group and 11 (10-13) in the novel risk-adapted screening approach group, respectively. Among them, the colonoscopy resource load of high-risk individuals in the novel risk-adapted screening approach group was 12 (9-15). FIT resource loads (95%CI) were 207 (196-218) and 88 (83-94) in the FIT group and the novel risk-adapted screening approach group. Conclusion: The combined application of risk-adapted screening approach and FIT may have a good application effect in colorectal cancer screening.

Abstract
Primary aldosteronism (PA) patients diagnosed with aldosterone-producing adenoma and unilateral adrenal hyperplasia are preferred for surgical treatment.The aim of the operation is to remove the hypersecretory aldosterone tissue of adrenal and to improve the prognosis.Current studies have shown that both partial adrenalectomy and total adrenalectomy can achieve clinical cure for PA, but the choice of surgical methods is still controversial. This paper discusses the efficacy and safety, postoperative changes in cortisol level, postoperative recurrence and surgical techniques of different surgical methods in the treatment of different PA subtypes, so as to find the best surgical methods for different PA subtypes and to maximize the benefits for patients.

Abstract
Objective: To investgate the effect of properative transitional zone index (TZI) on the outcome of transurethral resection of prostate (TURP). Methods: A retrospective analysis was performed on 206 patients with TURP who were admitted to our hospital from January 2016 to September 2018. All patients underwent transrectal ultrasound (TRUS) to determine the total prostate volume (TPV) and the transition zone volume (TZV). Patients were divided into two groups according to TZI (TZV/TPV) (group A: TZI<0.5, group B: TZI≥0.5). We collected data 6-months after surgery including international prostate symptom score (IPSS), quality of life score (QOL), maximum flow rate (Qmax), and postvoiding residue (PVR) to compare the difference of the postoperative outcome of two groups, while the IPSS was subdivided into voiding (IPSS-v) and storage(IPSS-s) symptoms, and the changes of IPSS, IPSS-v, IPSS-s, QOL, Qmax and PVR before and after surgery were analyzed. The treatment efficacy was determined as the changes of IPSS (post/preoperative IPSS: %IPSS), QOL (preoperative QOL-postoperative QOL: ΔQOL) and Qmax(preoperative Qmax-postoperative Qmax: ΔQmax). Pearson linear correlation analysis was employed to estimate the correlation of TZI and %IPSS, ΔQOL and ΔQmax, respectively. Results: A total of 126 patients were in Group A, and 80 patients were in group B. 1. The preoperative clinical data of the two groups were compared. There were no significant differences regarding age, IPSS, IPSS-v, IPSS-s, QOL, Qmax, and PVR between two groups (all P>0.05). However, the TPV of patients in group B (74.57±29.25) ml was significantly larger than that in group A (46.25±24.56) ml, P<0.001. While the postoperative follow-up outcomes of the two groups were compared, we found that IPSS-s (P=0.079), QOL (P=0.710), and PVR (P=0.651) were not statistically different between the two groups, but the postoperative IPSS, IPSS-v, and Qmax (8.50±5.75 vs 6.38±4.36, 4.03±3.75 vs 2.63±2.5, and (16.54±4.43) ml/s vs (18.94±4.84) ml/s, all P<0.05) were significantly different between the two groups. 2. Postoperative IPSS, IPSS-v, IPSS-s, QOL, Qmax and PVR were significantly different from those before surgery in two groups, respectively. 3. Pearson linear correlation analysis showed a significant positive correlation between TZI and ΔQmax (r=0.32, P<0.01), a weaker negative correlation between TZI and %IPSS (r=-0.22, P<0.01), and no correlation between TZI and ΔQOL (r=0.08, P=0.238). Conclusion: There may be a correlation between the outcome of TURP and TZI, and the outcome of TURP may be better in patients with TZI ≥ 0.5.

Abstract
Objective: To study the improvement of lower urinary tract symptoms and related influencing factors in patients with prostate cancer complicated with lower urinary tract symptoms after drugs endocrine therapy. Methods: The clinical data of 80 patients with prostate cancer with lower urinary tract symptoms and receiving drug endocrine therapy in Guizhou Provincial People's Hospital from March 2015 to June 2019 were analyzed retrospectively. All patients were followed up, and the mode of administration of the endocrine therapy, the time of administration, and the international prostate symptom score (IPSS2) and quality of life score (QOL2) after treatment were recorded. The improvement of IPSS score and quality of life score after endocrine therapy was observed. The correlation between variance and age, the prostate volume, PSA, tumor stage, Gleason score, symptom severity, medication mode, and medication time were analyzed by variance, chi-square test and paired sample t test. Results: The differences of QOL and IPSS before and after therapy were statistically significant (P<0.05). Chi-square test found that the effective rate of drug endocrine therapy was not related to age (χ2=0.800; P=0.371), tumor stage (χ2=0.094; P=0.759), PSA (χ2=0.651; P=0.420), prostate volume (χ2=0.216; P=0.642), Gleason score (χ2=0.157; P=0.692), symptom severity (χ2=0.457; P=0.499), medication mode (χ2=2.910; P=0.233), and medication time (χ2=4.159; P=0.385). Analysis of variance found that prostate volume and the severity of symptoms was significantly associated with improvement in lower urinary tract symptoms. Conclusions: Drug endocrine therapy can effectively improve the lower urinary tract symptoms of patients with prostate cancer, and the more severe the symptoms and prostate volumeof the patients, the more obvious the improvement of lower urinary tract symptoms. The age, tumor stage, PSA, Gleason score, time and manner of administration were not significantly correlated with improvement in lower urinary tract symptoms.

Abstract
Objective: To investigate the pathological characters of urothelial barrier in prostatic ducts of elderly male SD rats. Methods: Ten elderly male SD rats were anesthetized with chloral hydrate and then took the bladder, prostatic urethra and prostate tissues for serial pathological sections and HE staining. Immunohistochemical method was used to detect the expression of the Cytokeratin 7 (CK7), Cytokeratin 20 (CK20), Uroplakin Ⅲ (UP Ⅲ), Zonula occludens-1 (ZO-1) and Occludin in issues, and to make densitometric analysis (IA) on immunohistochemical results of each antibody. Results: HE staining observed that urothelial umbrella cells exist in the bladder, prostatic urethra and proximal prostatic duct. Immunohistochemical method showed the CK7, UPⅢ, ZO-1 and Occludin were positive in bladder, prostatic urethra and prostatic duct, while CK20 was negative. CK7 and UPⅢ were positive in the proximal prostatic duct, and negative in the bottom of the ductal acinar lumen; ZO-1 and Occludin were positive in prostatic duct. The IOD/Area values of CK7 and UP Ⅲ, in bladder, prostatic urethra, proximal prostatic duct, the middle of prostatic duct and bottom of the ductal acinar lumen, were 0.16, 0.13, 0.06, 0.05, 0.00 and 0.17, 0.16, 0.08, 0.05, 0.00(P<0.05,respectively). The expression of ZO-1 and Occludin in bladder (0.14 and 0.13) were higher than those in other tissues (0.11-0.12 and 0.09-0.10, P<0.05); the expression of ZO-1 and Occludin, which in proximal prostatic duct to the middle of prostatic duct and bottom of the ductal acinar lumen, had no significant difference (0.12-0.11 and 0.09-0.09, P>0.05). The IA values of CK20 were extremely low (0.00-0.01, P>0.05). Conclusion: Urothelial barriers partially exist in the prostatic ducts of elderly male SD rats, and with the prostatic ducts gradually extending to the bottom of acinar lumen, the urothelial barriers disappear. The results lay a foundation for further study on the repair of urinary epithelial barrier after prostatectomy.

Abstract
Objective: To investigate the clinical effect and safety of long-acting pegylated interferon-α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 μg/week) in the treatment of HBeAg-positive chronic hepatitis B (CHB) patients, with standard-dose Peg-IFN-α-2a as positive control. Methods: This study was a multicenter, randomized, open-label, and positive-controlled phase III clinical trial. Eligible HBeAg-positive CHB patients were screened out and randomized to Peg-IFN-α-2b (Y shape, 40 kD) trial group and Peg-IFN-α-2a control group at a ratio of 2:1. The course of treatment was 48 weeks and the patients were followed up for 24 weeks after drug withdrawal. Plasma samples were collected at screening, baseline, and 12, 24, 36, 48, 60, and 72 weeks for centralized detection. COBAS® Ampliprep/COBAS® TaqMan® HBV Test was used to measure HBV DNA level by quantitative real-time PCR. Electrochemiluminescence immunoassay with Elecsys kit was used to measure HBV markers (HBsAg, anti-HBs, HBeAg, anti-HBe). Adverse events were recorded in detail. The primary outcome measure was HBeAg seroconversion rate after the 24-week follow-up, and non-inferiority was also tested. The difference in HBeAg seroconversion rate after treatment between the trial group and the control group and two-sided confidence interval (CI) were calculated, and non-inferiority was demonstrated if the lower limit of 95% CI was > -10%. The t-test, chi-square test, or rank sum test was used according to the types and features of data. Results: A total of 855 HBeAg-positive CHB patients were enrolled and 820 of them received treatment (538 in the trial group and 282 in the control group). The data of the full analysis set showed that HBeAg seroconversion rate at week 72 was 27.32% in the trial group and 22.70% in the control group with a rate difference of 4.63% (95% CI -1.54% to 10.80%, P = 0.1493). The data of the per-protocol set showed that HBeAg seroconversion rate at week 72 was 30.75% in the trial group and 27.14% in the control group with a rate difference of 3.61% (95% CI -3.87% to 11.09%, P = 0.3436). 95% CI met the non-inferiority criteria, and the trial group was non-inferior to the control group. The two groups had similar incidence rates of adverse events, serious adverse events, and common adverse events. Conclusion: In Peg-IFN-α regimen for HBeAg-positive CHB patients, the new drug Peg-IFN-α-2b (Y shape, 40 kD) has comparable effect and safety to the control drug Peg-IFN-α-2a.

Methods: Clinical data of 249 BPH patients received TmLRP-TT or TURP were retrospectively collected. Patients were divided into small prostate group [prostate volume (PV)<40 ml], medium prostate group (40 ml≤PV<80 ml) and large prostate group (PV ≥ 80 ml) based on transrectal ultrasound (TRUS) results. Age, PV, Prostate-specific antigen (PSA), International prostate symptom score (IPSS), Quality of life (QoL), maximum of flow rate (Q(max)) and post-void residual urine (PVR) of patients received TmLRP-TT or TURP in each group were analyzed, as well as the perioperative data including operation time, hemoglobin and serum sodium level, transfusion, postoperative length of indwelling catheter and postoperative hospital stay. Furthermore, the postoperative complication rates of patients received the two operative methods in each group up to follow-up of 6 months were compared. Results: As for baseline indicators, there were no significant differences regarding age, prostate volume, PSA, IPSS, QoL, Qmax and PVR of patients received TmLRP-TT or TURP in each group (all P>0.05). In the small prostate group, there were no significant differences with operation time, hemoglobin and serum sodium level, transfusion, postoperative length of indwelling catheter and postoperative hospital stay received TmLRP-TT or TURP (all P>0.05). For the medium prostate group, patients received TmLRP-TT underwent longer operation time [(67.4±15.1) vs (57.5±11.5) min, P<0.001], but shorter length of indwelling catheter [(1.5±0.6) vs (3.1±0.9) d, P<0.001] and postoperative hospital stay [(3.5±0.9) vs (5.6±1.0) d, P<0.001], and there were no significant differences regarding transfusion rate (3/73 vs 1/78, P=0.280), hemoglobin [(9.8±9.0) vs (12.2±9.6) g/L, P=0.107] and serum sodium decrease [(2.07±3.65) vs (2.97±3.35) mmol/L, P=0.373]. In the large prostate group, patients received TmLRP-TT also underwent longer operation time [(86.5±14.3) vs (76.7±14.6) min, P=0.022], but less hemoglobin [(11.3±13.8) vs (23.3±15.0) g/L, P=0.006] and serum sodium decrease [(2.41±2.67) vs (4.00±6.22) mmol/L, P=0.042], lower transfusion rate (5/27 vs 0/24, P=0.026), and shorter length of indwelling catheter [(1.8±0.7) vs (4.3±1.5) d, P<0.001] as well as postoperative hospital stay [(3.7±1.1) vs (6.1±1.7) d, P<0.001]. Less overall complications were encountered in the medium (38/73 vs 24/78, P=0.008) and large (26/27 vs 10/24, P<0.001) prostate group who received TmLRP-TT, which was not seen in the small prostate group (P=0.589). Conclusions: TmLRP-TT and TURP are similarly efficient for the treatment of BPH of various sizes. For BPH patients with medium and large prostate, TmLRP-TT demonstrated significant advantages in reducing the overall complications, although the operation time was slightly longer.

Abstract
Objective: To investigate the efficacy and safety of the new investigational drug pegylated interferon α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 µg/week) combined with ribavirin in the treatment of patients with genotype 1/6 chronic hepatitis C (CHC), with standard-dose Peg-IFN-α-2a combined with ribavirin as a positive control. Methods: A multicenter, randomized, open-label, and positive-controlled phase III clinical trial was performed. Eligible patients with genotype 1/6 CHC were screened out and randomly divided into Peg-IFN-α-2b(Y shape, 40kD) group and Peg-IFN-α-2a group at a ratio of 2:1. The patients in both groups were given oral ribavirin for 48 weeks in addition and then followed up for 24 weeks after drug withdrawal. Abbott Real Time HCV Genotype II was used to determine HCV genotype, and Cobas TaqMan quantitative real-time PCR was used to measure HCV RNA level at 0, 4, 12, 24, 48, and 72 weeks. Adverse events were recorded in detail. The primary efficacy endpoint was sustained virological response (SVR), and a non-inferiority test was also performed. Results: A total of 561 patients with genotype 1/6 CHC were enrolled, among whom 529 received treatment; 90.9% of these patients had genotype 1 CHC. The data of the full analysis set showed that SVR rate was 69.80% (95% CI 65.00%-74.60%) in the trial group and 74.16% (95% CI 67.73%-80.59%) in the control group (P = 0.297 0). The data of the per protocol set (PPS) showed that SVR rate was 80.63% (95% CI 76.04%-85.23%) in the trial group and 81.33% (95% CI 75.10%-87.57%) in the control group (P = 0.849 8), and the 95% CI of rate difference conformed to the non-inferiority standard. The analysis of the PPS population showed that of all subjects, 47.9% achieved rapid virologic response, with a positive predictive value of 93.8%. The incidence rate of adverse events was 96.30% in the trial group and 94.94% in the control group, and the incidence rate of serious adverse events was 5.13% in the trail group and 5.06% in the control group. Conclusion: In the regimen of Peg-IFN-α combined with ribavirin for the treatment of genotype 1/6 CHC, the new investigational drug Peg-IFN-α-2b(Y shape, 40 kD) has comparable clinical effect and safety to the control drug Peg-IFN-α-2a.

Abstract
PURPOSE The study aimed to perform an anatomical observation on the inferomedial extension of the renal fascia (RF) to the pelvis and explore its relationship with the hypogastric nerves (HGNs). METHODS Gross anatomy was performed on 12 formalin-fixed and 12 fresh cadavers. Sectional anatomy was performed on four formalin-fixed cadavers. RESULTS Different from the traditional concept, both the anterior and posterior RF included the outer and inner layer with different inferomedial extensions. The multiple layers of RF extended downward to form a sandwich-like and compound fascia sheath with potential and expandable spaces which was named as "the urogenital-hypogastric sheath." Below the level of the origin of the inferior mesenteric artery, the bilateral urogenital-hypogastric sheath communicated with the counterpart in front of the great vessels in the midline and the superior hypogastric plexus ran into the urogenital-hypogastric sheath which carried the HGNs, ureters, and genital vessels downward to their terminations in the pelvis. In the retrorectal space, the urogenital-hypogastric sheath surrounded the fascia propria of the rectum posterolaterally as a layer of coat containing HGNs. CONCLUSION The multiple layers of RF with different extensions are the anatomical basis of the formation of the urogenital-hypogastric sheath. As a special fascial structure in the retroperitoneal space and the pelvis, emphasis on its formation and morphology may be helpful for not only unifying the controversies about the relationship between the pelvic fascia and HGNs but also improving the intraoperative preservation of the HGNs by dissecting in the correct surgical plane.

Abstract
UNLABELLED Citrate synthase (CS) is the one of the key enzymes in the citric acid cycle and an important mitochondrial autoantigen. The autoimmune responses against CS have not been studied in chronic allograft nephropathy (CAN). This study investigated the role of specific CS autoantibodies in rats bearing renal allografts affected with CAN. METHODS Fisher344 rat renal grafts were orthotopically transplanted into Lewis rats following the procedure of Kamada with our modification. Lewis-to-Lewis and Fisher344-to-Fisher344 kidney transplantations were also performed as autologous control groups (each n = 9). All the allograft recipients given cyclosporine (10 mg/kg(-1)d(-1) x 10 d) were divided into four groups (each n = 9): (1) vehicle: normal saline orally; (2) cyclosporine: 6 mg/kg(-1)d(-1); (3)FK506: 0.15 mg/kg(-1)d(-1); (4) mycophenolate mofetil (MMF): 20 mg/ kg(-1)d(-1). At 4, 8, and 12 weeks posttransplantation, the animals were sacrificed to harvest sera and renal allografts. The serum creatinine (SCr) was measured and pathological changes assessed according to Banff 97 criteria. IgM and IgG isotypes of CS antibodies were detected in all recipient sera by enzyme linked immunosorbent assays. RESULTS Both IgM and IgG isotype CS autoantibodies were observed in the sera of all the recipients before and after transplantation, but the levels of IgM CS autoantibody were obviously higher than IgG isotype in all the blood samples. It was stable not only in autologous but also in allograft groups. In both autologous groups, the SCr and IgM and IgG isotype CS autoantibodies showed no obvious change before and after transplantation, and no typical CAN occurred. The values of IgG isotype of CS autoantibody (DeltaOD) at 4, 8 and 12 weeks were stable. At 4 weeks, the values of SCr, Banff score, and IgG isotype CS autoantibody (DeltaOD) were not significantly different (P > .05) among the allograft groups. At 8 and 12 weeks, with progression of CAN in vehicle, cyclosporine and FK506 groups' values of SCr, Banff score, and IgG (DeltaOD) also increased dramatically (P = .005) in all three groups when compared with the baseline and 4 week values, but the differences among the three groups were not significant (P > .05). At 8 and 12 weeks, the MMF group suffered mild-to-moderate CAN, but the values of SCr and Banff score were significantly lower than those in the other three groups. MMF significantly inhibited the formation of IgG (DeltaOD) when compared with the other three groups (P = .02). CONCLUSION This study suggested that the IgG isotype of CS autoantibody contributes to CAN after kidney transplantation. The IgM isotype is physiological. MMF significantly inhibited the formation of IgG isotype CS autoantibody, which may be related to its effects to alleviate CAN.

Abstract
OBJECTIVE Angiopoietin-1 (Ang1) and -2(Ang2) are 2 ligands for the endothelium-specific tyrosine kinase Tie2. Previous studies have shown that reciprocal regulation of Ang1, Ang2, and Tie2 plays an important role in chronic cardiac allograft vasculopathy. This study investigated the expressions of Ang1, Ang2, and Tie2 in rat renal allografts undergoing chronic allograft nephropathy (CAN). MATERIALS AND METHODS Renal transplantations following the procedure of Kamada with our modification were orthotopically performed using Fisher (F344, RT1(1v1)) rats as both donors and recipients in the autograft group. Fisher and Lewis (LEW, RT1(1)) rats were used as donors and recipients in the allograft group, respectively, which was treated with cyclosporine (CsA; 10 mg/kg/d x 10 d). At 4w, 8w, and 12 weeks posttransplantation, serum creatinine (SCr) was measured and pathologic changes assessed according to the Banff 97 criteria. The mRNA (Deltact) and protein expressions of Ang1, Ang2, and Tie2 were localized by real-time fluorescence quantitative polymerase chain reaction (PCR) and by immunohistochemistry. RESULTS The elevation in SCr and the pathologic changes in CAN were observed in all allografts at 8 and 12 weeks. The expressions of Ang1 and Ang2 were localized to epithelial cells and endothelium of the vascular bundles of the glomeruli; Tie2 was specifically expressed in endothelium of vessels both in auto- and allografts at all time points posttransplantation. At 4 weeks, the differences in mRNA expression of Ang1, Ang2, and Tie2 between the 2 groups were not significant (P > .05). Compared with autografts, the mRNA expression of Ang1 decreased significantly (P = .008 and .003 for 8 and 12 weeks, respectively), and the mRNA expressions of Ang2 and Tie2 significantly increased (P = .001/.006 and .005/.001 for 8 and 12 weeks, respectively). The changes in expression of all 3 genes showed significant correlation with the Banff score in the allografts. CONCLUSION This study suggested that the abnormal expression and reciprocal regulation of Ang1, Ang2, and Tie2 may play important roles in the development of CAN in rat renal allografts.

Abstract
AIM Epithelial-mesenchymal transformation (EMT) has been proved to be a critical event in fibrogenesis of renal allografts. This study sought to determine whether anoxia could induce EMT from tubular epithelial cells (TEC). METHODS Rat TEC-line (NRK-52E) was cultured in Dulbelco's modified Eagle's medium (DMEM) without glucose under 100% N2 for 4 hours. After 6, 12, 24, 48, and 72 hours, the expressions of connective tissue growth factor (CTGF) mRNA and protein were measured by real-time RT-PCR and Western blot, respectively. Morphologic changes and cytoskeleton remodeling were observed in NRK-52E cells under laser confocal microscopy. Immunohistochemistry and flow cytometry were used to detect expression changes of E-cadherin, alpha-smooth muscle actin (SMA), types I and IV collagen, all of which are involved in TEC, EMT. RESULTS After stimulation by anoxia, NRK-52E cells became round and enlarged with a remodeled cytoskeleton. The expressions of CTGF mRNA and protein were upregulated after 6 hours, reaching their peak at 48 hours. The expressions of types I and IV collagen, and alpha-SMA were all upregulated except for E-cadherin. CONCLUSIONS Anoxia upregulated the expression of CTGF and other EMT-associated genes in NRK-52E cells.

Abstract
OBJECTIVE Previous studies have indicated that angiopoietin-1 (Ang1) and angiopoietin-2 (Ang2) and tyrosine kinase receptor Tie2 regulate the maintenance and integrity of blood vessels and have potential anti-inflammatory properties. This study of cardiac allografts investigated whether there is a difference between rapamycin and cyclosporine A (CsA) in the ability to affect expression of Ang1, Ang2, and Tie2 in rat renal allografts with chronic allograft nephropathy (CAN). METHODS A male inbred F344 to Lewis rat renal CAN model was established via a modified Kamada procedure. The recipients were first treated with CsA, 10 mg/kg/d, for 10 days and then allocated randomly to three oral treatment groups: control; CsA, 6 mg/kg/d; and rapamycin, 0.8 mg/kg/d. At 4, 8, and 12 weeks posttransplantation, the rats were killed to harvest the renal allografts. The serum creatinine concentration (SCr) was measured, and the pathologic changes were assessed according to Banff 97 criteria. The expression of messengerRNA and proteins of Ang1, Ang2, and Tie2 was determined using real-time fluorescence quantitative polymerase chain reaction and immunohistochemistry. RESULTS The elevation of SCr and the pathologic changes of CAN were observed in the control and CsA groups at 8 and 12 weeks; the differences between the 2 groups were not significant (P > .05). The levels of SCr and Banff score in the rampamycin group were lower than those in other 2 groups (P < .01). The expression of Ang1 and Ang2 was localized to epithelial cells and endothelium of vascular bundles of glomeruli, and Tie2 was specifically expressed in the endothelium of vessels in all 3 groups. At 4 weeks, the differences in mRNA expression of Ang1, Ang2, and Tie2 between 3 groups were not significant (P > .05). In a comparison of the control and CsA groups, mRNA expression of Ang1 was increased (P < .05), and mRNA expression of Ang2 and Tie2 was decreased (P < .05) in the rapamycin group at 8 and 12 weeks. The differences between the control and CsA groups were not significant at 8 or 12 weeks (P > .05). CONCLUSIONS Our results show that compared with CsA, rapamycin modulates the expression of Ang1, Ang2, and Tie2 in rat renal allografts with CAN, which suggests that rapamycin may improve the long-term survival of renal allografts through its vasculoprotective properties.

Abstract
AIMS Antivimentin antibody is often produced as an autoantibody after transplantation. C4d deposition, a marker of humoral immunity during transplantation, is believed to reflect alloantibodies. This study investigated the relationship between C4d deposition and humoral immunity to vimentin among rat kidneys undergoing chronic allograft nephropathy (CAN). METHODS Fisher 344 rat renal grafts were orthotopically transplanted into Lewis rats following the procedure of Kamada with our modification. All recipients were administered cyclosporine (CsA) (10 mg/kg(-1).d(-1) x 10 d) before being divided into 3 groups of oral treatments: (1) vehicle, (2) CsA (6 mg/kg(-1).d(-1)), and (3) mycophenolate mofetil (MMF; 20 mg/kg(-1).d(-1)). At 4, 8 and 12 weeks after transplantation, the rats were killed, the renal allografts harvested, and the sera collected. Serum creatinine (SCr) was measured and pathologic changes assessed according to the Banff 97 criteria. The antivimentin antibody was quantified by enzyme-linked immunosorbent assay. The deposition of C4d detected by immunofluorescence was analyzed by integrated optical density (IOD). RESULTS Antivimentin antibody was observed in sera of all transplanted rats. The level of antivimentin antibody (IgGDeltaOD) increased gradually during the development of CAN from 4 weeks. Simultaneously, C4d deposition in peritubular capillaries also progressively strengthened. There was a strong positive correlation between the content of antivimentin antibody and C4d deposition (r = 0.892; P = .000). MMF simultaneously decreased antivimentin antibody formation and C4d deposition. In contrast, CsA had no significant effect. CONCLUSIONS We demonstrated the production of antivimentin antibodies and the deposition of C4d during the development of CAN. There was a positive correlation between them. Whether humoral immunity to vimentin contributes to C4d deposition is not clear and further studies are needed to elucidate this issue.

Abstract
AIM Connective tissue growth factor (CTGF) is a highly profibrogenic molecule implicated in renal fibrogenesis. Small interfering RNA (siRNA) is an effective tool to silence gene expression. This study determined whether caudal vein injection of siRNA targeting CTGF inhibited its expression in rat kidneys in vivo, and furthermore whether it protected the kidney from renal fibrosis in chronic allograft nephropathy (CAN). METHODS Male inbred Fischer (F344, RT1(lv1)) rat renal grafts were orthotopically transplanted into Lewis (LEW, RT1(1)) rats following the procedure of Kamada with our modification. At 6 weeks, recipients were divided into siRNA, normal saline (NS), and control siRNA groups, using daily siRNA-targeting CTGF (0.1 mg/kg), or NS, or a control siRNA via caudal vein injection for 14 days. At 4, 6, and 8 weeks, we observed the pathologic changes, expression of CTGF, E-cadherin, collagen I and IV, and anti-smooth muscle actin (alpha-SMA). RESULTS Serum creatinine level, Banff score, and the expression of CTGF were significantly lower among the siRNA than the NS or the control siRNA groups at 8 weeks (P < .05). The expressions of collagen I and IV, and alpha-SMA were also significantly downregulated and E-cadherin was lost in the siRNA versus the NS and control siRNA groups at 8 weeks. CONCLUSIONS This study showed that delivery of CTGF siRNA via the caudal vein significantly inhibited expression of CTGF in rat kidneys, effectively preventing fibrosis in CAN. The results suggest that siRNA-targeting of CTGF has the potential to be a novel strategy for amelioration of CAN.
