Abstract
OBJECTIVE This study aimed to investigate the effects of sex hormone imbalance on rat prostatic inflammation and fibrosis and identify the key molecules involved. METHODS Castrated Sprague-Dawley (SD) rats were treated with a constant dose of oestradiol (E2) and different doses of dihydrotestosterone (DHT) to achieve different oestrogen/androgen ratios. After 8 weeks, serum E2 and DHT concentrations, relative seminal vesicle weights, histopathological changes and inflammation were measured, collagen fiber content and oestrogen receptor (ER) and androgen receptor (AR) expression were detected, mRNA sequencing and bioinformatics analysis were performed to identify differentially expressed genes (DEGs). RESULTS The severity of inflammation in the rat dorsolateral prostate (DLP) was higher, collagen fibre content and ER expression in the rat DLP and prostatic urethra were increased and AR expression in the rat DLP was decreased in the 1:1 E2/DHT-treated group than that in the 1:10 E2/DHT-treated group. RNA-seq analysis identified 487 DEGs, and striking increases in the expression of mRNAs encoding collagen, collagen synthesis and degradation enzymes, growth factors and binding proteins, cytokines and chemokines, and cell-surface molecules were confirmed in the 1:1 E2/DHT-treated group compared to the 1:10 E2/DHT-treated group. mRNA expression of secreted phosphoprotein 1 (Spp1) and protein expression of osteopontin (OPN, encoded by Spp1) were increased in the 1:1 E2/DHT-treated group compared to the 1:10 E2/DHT-treated group, and Spp1 expression correlated positively with Mmp7, Cxcl6 and Igfn1 expression. CONCLUSIONS The imbalance in the oestrogen/androgen ratio may affect rat prostatic inflammation and fibrosis, and OPN might be involved in this process.

Abstract
Non-coding RNA appears to be involved in wound repair. Competing endogenous RNA (ceRNA) appears to be an important post-transcriptional mechanism, it means that long noncoding RNA (lncRNA) or circular RNA (circRNA) acts as a microRNA (miRNA) sponge to further regulate mRNA. However, ceRNA network related to wound repair after prostatectomy has yet been constructed. TULP is the main surgical method of prostatectomy, but there have been no reports of TULP rat models in the past. We simulated TULP on rats, and observed the whole process of wound injury and repair after operation through pathological examination of wound tissue. Next, we discovered 732 differentially expressed lncRNAs (DElncRNAs), 47 differentially expressed circRNAs (DEcircRNAs), 17 differentially expressed miRNAs (DEmiRNAs), and 1892 differentially expressed mRNAs (DEmRNAs) related to wound repair after TULP through full transcriptome microarray and bioinformatics methods, and confirmed the reliability of transcriptome data by quantitative Reverse Transcription PCR (qRT-PCR), and immunohistochemistry. Then, we constructed the lncRNA- and circRNA-associated ceRNA regulatory networks related to wound repair after TULP in rats. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses showed that molecules in these networks were mainly involved in inflammatory infiltration, cell differentiation, and intercellular interactions and involved signal pathways such as the PI3K-Akt signaling pathway. Thus, this study successfully established the TULP model in rats, revealed potentially important biomarkers and ceRNA networks after prostatectomy in rats, and provided theoretical support for the repair of post-prostatectomy wound.

Abstract
Objective The aim of the present study was to observe the effect of the stroma proportion in hyperplasia nodules on the clinical symptoms of benign prostatic hyperplasia (BPH) patients and to identify the different genes and pathways in prostatic hyperplasia nodules between patients with epithelial-dominated hyperplasia (EDH) and stromal-dominated hyperplasia (SDH) nodules. Methods Sixty-seven BPH patient samples underwent transurethral resection of the prostate (TURP) were collected and retrospectively analyzed. The differences in clinical parameters between the EDH and SDH groups were investigated. Collagen fiber percentage was assessed, and the correlation with clinical parameters was evaluated. mRNA sequencing in hyperplasia nodules of 8 BPH patients was performed, and differentially expressed genes (DEGs) between the EDH and SDH groups were screened. These DEGs were analyzed using GO, KEGG and PPI analysis. Results The results showed the IPSS was significantly higher in the SDH group than in the EDH group (p < 0.01). The collagen fiber percentage of BPH nodules was higher in the SDH group than in the EDH group (p < 0.05), and the collagen fiber percentage was positively correlated with the IPSS (r = 0.4058, p = 0.0007). A total of 172 DEGs were obtained, including 63 up-regulated genes and 109 down-regulated genes. GO and KEGG pathway enrichment analyses showed DEGs were mainly enriched in extracellular matrix structural constituents. The top 10 hub genes were associated to the components of extracellular matrix and fibrosis. Conclusion These results suggested that the symptoms of BPH patients with SDH nodules may be associated with prostate fibrosis and fibrosis may be a significant contributing factor in BPH/LUTS patients with SDH nodules.

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
Benign prostatic hyperplasia (BPH) is highly prevalent among older men, impacting on their quality of life, sexual function, and genitourinary health, and has become an important global burden of disease. Transurethral plasmakinetic resection of prostate (TUPKP) is one of the foremost surgical procedures for the treatment of BPH. It has become well established in clinical practice with good efficacy and safety. In 2018, we issued the guideline "2018 Standard Edition". However much new direct evidence has now emerged and this may change some of previous recommendations. The time is ripe to develop new evidence-based guidelines, so we formed a working group of clinical experts and methodologists. The steering group members posed 31 questions relevant to the management of TUPKP for BPH covering the following areas: questions relevant to the perioperative period (preoperative, intraoperative, and postoperative) of TUPKP in the treatment of BPH, postoperative complications and the level of surgeons' surgical skill. We searched the literature for direct evidence on the management of TUPKP for BPH, and assessed its certainty generated recommendations using the grade criteria by the European Association of Urology. Recommendations were either strong or weak, or in the form of an ungraded consensus-based statement. Finally, we issued 36 statements. Among them, 23 carried strong recommendations, and 13 carried weak recommendations for the stated procedure. They covered questions relevant to the aforementioned three areas. The preoperative period for TUPKP in the treatment of BPH included indications and contraindications for TUPKP, precautions for preoperative preparation in patients with renal impairment and urinary tract infection due to urinary retention, and preoperative prophylactic use of antibiotics. Questions relevant to the intraoperative period incorporated surgical operation techniques and prevention and management of bladder explosion. The application to different populations incorporating the efficacy and safety of TUPKP in the treatment of normal volume (< 80 ml) and large-volume (≥ 80 ml) BPH compared with transurethral urethral resection prostate, transurethral plasmakinetic enucleation of prostate and open prostatectomy; the efficacy and safety of TUPKP in high-risk populations and among people taking anticoagulant (antithrombotic) drugs. Questions relevant to the postoperative period incorporated the time and speed of flushing, the time indwelling catheters are needed, principles of postoperative therapeutic use of antibiotics, follow-up time and follow-up content. Questions related to complications incorporated types of complications and their incidence, postoperative leukocyturia, the treatment measures for the perforation and extravasation of the capsule, transurethral resection syndrome, postoperative bleeding, urinary catheter blockage, bladder spasm, overactive bladder, urinary incontinence, urethral stricture, rectal injury during surgery, postoperative erectile dysfunction and retrograde ejaculation. Final questions were related to surgeons' skills when performing TUPKP for the treatment of BPH. We hope these recommendations can help support healthcare workers caring for patients having TUPKP for the treatment of BPH.

Abstract
BACKGROUND Drainage tube removal is difficult when the greater omentum becomes incarcerated in the drainage tube through the side holes. Currently, known removal methods are either ineffective or will cause additional damage to the patient in a secondary operation. Ureteroscopy and the holmium laser have been used in various surgical techniques in urology, and in theory, they are expected to be a good strategy for solving the problem of tissue incarceration.
CASE SUMMARY Four patients diagnosed with difficult removal of an abdominal drainage tube following abdominal surgery are reported. All patients underwent surgery to remove the incarcerated greater omentum in the drainage tube using a holmium laser and a ureteroscope, and a new 16-F drain was then placed in the abdominal or pelvic cavity. The efficacy of this technique was evaluated by intraoperative conditions, success rate, and operating time; safety was evaluated by perioperative conditions and the probability of postoperative complications. All four operations went smoothly, and the drains were successfully removed in all patients. The average operating time was 24.5 min. Intraoperatively, the average irrigation volume was 892.0 mL, the average drainage volume was 638.5 mL, and no bleeding or damage to surrounding tissues was observed. Postoperatively, the average drainage volume was 32.8 mL and the new drains were removed within 36 h. All patients were able to get out of bed and move around within 12 h. Their visual analogue pain scores were all below 3. The average follow-up duration was 12.5 mo and no complications such as fever or bleeding were noted.
CONCLUSION Ureteroscopic holmium laser surgery is an effective, safe and minimally invasive technique for removing drains where the greater omentum is incarcerated in the abdominal drain.

Abstract
Sepsis is an acute inflammatory reaction and a cause of acute respiratory distress syndrome (ARDS). In the present study, we explored the roles and underlying mechanism of the lncRNA Nuclear enriched abundant transcript 1 (NEAT1) in ARDS. The expression levels of genes, proteins and pro-inflammatory cytokines in patients with ARDS, LPS-stimulated cells and septic mouse models were quantified using qPCR, western blotting and ELISA assays, respectively. The molecular targeting relationship was validated by conducting a dual-luciferase reporter assay. Cell proliferation was assessed using the Cell Counting Kit-8 (CCK-8) assay. The cell cycle phase was determined by flow cytometry assay. The expression levels of NEAT1 and pro-inflammatory cytokines were higher in patients with ARDS and septic models than in controls. Knockdown of NEAT1 significantly increased cell proliferation and cycle progression and prolonged mouse survival in vitro and in vivo. Mechanistically, miR-27a was identified as a downstream target of NEAT1 and directly inhibited PTEN expression. Further rescue experiments revealed that inhibition of miR-27a impeded the promoting effects of NEAT1 silence on cell proliferation and cycle progression, whereas inhibition of PTEN markedly weakened the inhibitory effects of NEAT1 overexpression on cell proliferation and cycle progression. Altogether, our study revealed that NEAT1 plays a promoting role in the progression of ARDS via the NEAT1/miR-27a/PTEN regulatory network, providing new insight into the pathologic mechanism behind ARDS.

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
On the basis of existing laparoscopic transabdominal adrenalectomy, this article described a safe and reliable surgical method for the treatment of small adrenal lesions-laparoscopic anatomical adrenalectomy (LAA), and retrospectively analyzed the clinical data of 74 patients who had undergone LAA. All patients had no signs of recurrence on imaging. LAA has high safety and feasibility, clear intraoperative anatomical layers, good spatial operability, and low postoperative complications. LAA provides a more reliable option for the treatment of small adrenal diseases.

Abstract
Benign prostatic hyperplasia (BPH) is a common disease in elderly men, and transurethral laser prostatectomy (TULP) has been widely used in the clinic to remove bladder outlet obstruction caused by BPH. Previous animal models for wound repair after prostatectomy have many limitations, and there have been no previous reports of a mouse model of TULP. Therefore, this study aimed to establish a novel mouse model of TULP. Twelve healthy adult Kunming (KM) mice received transurethral laser vaporization prostatectomy with a 200-μm thulium laser. The mice were sacrificed, and wound specimens from the prostatic urethra and bladder neck were harvested at 1 day, 3 days, 5 days, and 7 days after surgery. Hematoxylin-eosin (HE) and immunohistochemistry were applied to confirm the establishment of the mouse TULP model. One day after the surgery, urothelium expressing uroplakin (UPK) was absent in the urethral wound site, and a large number of necrotic tissues were found in the wound site. There was no UPK-positive urothelium in the wound 3 days after surgery. At 5 days after surgery, monolayer urothelium expressing UPK was found in the wound site, indicating that the re-epithelization of the wound had been completed. On the 7th day after surgery, there were multiple layers of urothelium with UPK expression, indicating that the repair was completed. It is feasible to establish a mouse TULP model by using a microcystoscope system and a 200-μm thulium laser.

Abstract
Background To investigate the protective effects of exogenous spermine on renal ischemia-reperfusion injury in rats. Methods (I) Different doses of spermine were injected into rats to determine the safe dose on the kidneys. Kidney toxicity was assessed by hematoxylin and eosin (HE) staining of kidney tissue and enzyme-linked immunosorbent assay (ELISA) detection of neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule 1 (KIM-1) in the venous blood. (II) A rat model of renal ischemia-reperfusion injury was established. Different doses of spermine were injected into the rats through the tail vein 30 minutes before and 3 days after the establishment of the model. Blood samples and kidney tissues were collected and renal injury was assessed via HE staining of the renal tissue, detection of apoptosis using the TUNEL assay, and detection of NGAL and KIM-1 in blood samples using ELISA. (III) Human HK-2 renal tubular epithelial cells were cultured under hypoxia/reoxygenation conditions. To evaluate the protective effects of spermine, apoptosis was assessed by flow cytometry and TUNEL assay. The mechanisms underlying the effects of spermine were studied using Western blot analyses. Results At spermine concentrations below 200 µM (2 mL/kg body weight), no significant damage to the kidney was observed by HE staining, and there was no significant difference in NGAL and KIM-1 levels between rats treated with spermine and control rats (P<0.05). At spermine doses below 200 µM, HE staining showed that the degree of renal ischemia-reperfusion injury was gradually alleviated with increasing doses of spermine. TUNEL assays demonstrated that spermine reduced the apoptosis of renal tissue, and increasing doses of spermine gradually decreased the levels of NGAL and KIM-1 in the blood compared with the control group (P<0.05). Western blot analysis revealed that spermine increased the expression of pro-caspase9, phosphorylated protein kinase B (p-Akt), hypoxia-inducible factor 1 alpha (HIF-1α), B cell lymphoma 2 (Bcl-2), and Bcl2 interacting protein 3 (BNIP3), and decreased the expression of cleaved caspase-3, Bax and cytochrome C compared to control cells. Conclusions Exogenous spermine exerted a protective effect on renal ischemia-reperfusion injury in rats by inhibiting the apoptosis of renal tubular epithelial cells.

Abstract
We conducted the present study to assess the correlation of the prostatic anatomical parameters, especially the ratio of peripheral zone thickness and transitional zone thickness, with clinical and uroflowmetry characteristics suggestive of benign prostate hyperplasia (BPH). A total of 468 consecutive patients with a detailed medical history were identified. All patients were evaluated by scoring subjective symptoms with the International Prostate Symptom Score (IPSS) and quality of life (QoL). The prostatic anatomical parameters were measured using transrectal ultrasonography, and postvoid residual urine and maximum flow rate (Qmax) values were also determined. Pearson's correlation analysis revealed that both total prostate volume (TPV; r = 0.160, P < 0.001) and transitional zone volume (TZV; r = 0.104, P = 0.016) increased with patients' age; however, no correlations were observed of TPV, TZV, transitional zone index (TZI), and transitional zone thickness (TZT) with IPSS or QoL (all P > 0.05). Peripheral to transitional zone index (PTI) was found negatively correlated with total IPSS (r = −0.113, P = 0.024), storage IPSS (r = −0.103, P = 0.041), and voiding IPSS (r = −0.123, P = 0.014). As regards the uroflowmetry characteristics, PTI (r = 0.157, P = 0.007) was indicated to be positively correlated with Qmax and negatively correlated with TZI (r = −0.119, P = 0.042) and TZT (r = −0.118, P = 0.045), but not correlated with TPV, TZV, or peripheral zone thickness (PZT) (all P > 0.05). Postvoid residual urine (PVR) had not correlated with all the prostatic anatomical variables (all P > 0.05). This is the first study that formally proposed the concept of PTI, which is an easy-to-measure prostate anatomical parameter which significantly correlates with total IPSS, storage IPSS, voiding IPSS, and Qmax, suggesting that PTI would be useful in evaluating and managing men with lower urinary tract symptoms (LUTS)/BPH. However, well-designed studies are mandatory to verify the clinical utility of PTI.

Abstract
OBJECTIVE To evaluate the clinical application value of the bladder outlet obstruction index (BOOI) in the diagnosis of BPH. METHODS We retrospectively analyzed the urodynamic parameters and BOOI of 199 cases of BPH diagnosed from July 2016 to September 2018, which were divided into a BOO (n = 119), a suspected BOO (n = 39) and a non-BOO group (n = 41) based on the BOOI. We obtained the prostate volume (PV), IPSS, IPSS-voiding symptom score (IPSS-VS), quality of life score (QOL), maximum urinary flow rate (Qmax) and postvoid residual urine volume (PVR) from the patients, compared them among the three groups and analyzed their correlation to BOOI using Pearson's linear correlation analysis. RESULTS No statistically significant differences were observed in age (P = 0.195), PSA (P = 0.380), IPSS (P = 0.380), IPSS-VS (P = 0.380), QOL (P = 0.380), Qmax (P = 0.380) and PVR (P = 0.912) among the three groups of patients, but PV was remarkably larger in the BOO than in the suspected BOO and non-BOO groups ([58.8 ± 30.0] vs [49.8 ± 33.9] and [45.5 ± 26.0] ml, P = 0.031). Pearson's linear correlation analysis showed that BOOI was not correlated significantly to IPSS (r = -0.020, P = 0.778), IPSS-VS (r= -0.013, P = 0.853), QOL (r = -0.107, P = 0.132), Qmax (r = -0.130, P = 0.066) or PVR (r = -0.056, P = 0.433), nor obviously to PV (|r| = 0.178<0.4) though with P = 0.012. CONCLUSIONS BOOI is not significantly correlated to PV, IPSS, IPSS-VS, QOL, Qmax or PVR, and therefore BOO cannot be diagnosed exclusively with BOOI.

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.

Abstract
Objective: To compare the efficiency and safety of thulium laser resection of the prostate-tangerine technique (TmLRP-TT) and transurethral resection of the prostate (TURP) for the treatment of benign prostatic hyperplasia (BPH) of various sizes. 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
BACKGROUND Complications after a thulium laser resection of the prostate (TmLRP) are related to re-epithelialization of the prostatic urethra. Since prostate growth and development are induced by androgen, the aim of this study was to determine the role and explore the mechanism of androgen in wound healing of the prostatic urethra. METHODS Beagles that received TmLRPs were randomly distributed into a castration group, a testosterone undecanoate (TU) group, and a control group. The prostate wound was assessed once a week using a cystoscope. Histological analysis was then carried out to study the re-epithelialization of the prostatic urethra in each group. The inflammatory response in the wound tissue and urine was also investigated. RESULTS The healing of the prostatic urethra after a TmLRP was more rapid in the castration group and slower in the TU group than that in the control group. Castration accelerated re-epithelialization by promoting basal cell proliferation in the wound surface and beneath the wound and by accelerating the differentiation of basal cells into urothelial cells. Castration reduced the duration of the inflammatory phase and induced the conversion of M1 macrophages to M2 macrophages, thus accelerating the maturation of the wound. By contrast, androgen supplementation enhanced the inflammatory response and prolonged the inflammatory phase. Moreover, the anti-inflammatory phase was delayed and weakened. CONCLUSION Androgen deprivation promotes re-epithelialization of the wound, regulates the inflammatory response, and accelerates wound healing of the prostatic urethra after a TmLRP.

Abstract
The purpose of this study is to characterize the re-epithelialization of wound healing in canine prostatic urethra and to evaluate the effect of this re-epithelialization way after two-micron laser resection of the prostate (TmLRP). TmLRP and partial bladder neck mucosa were performed in 15 healthy adult male crossbred canines. Wound specimens were harvested at 3 days, and 1, 2, 3, and 4 weeks after operation, respectively. The histopathologic characteristics were observed by hematoxylin and eosin staining. The expression of cytokeratin 14 (CK14), CK5, CK18, synaptophysin (Syn), chromogranin A (CgA), uroplakin, transforming growth factor-β1(TGF-β1), and TGF-β type II receptor in prostatic urethra wound were examined by immunohistochemistry and real-time polymerase chain reaction, respectively. Van Gieson staining was performed to determine the expression of collagen fibers in prostatic urethra and bladder neck would. The results showed that the re-epithelialization of the prostatic urethra resulted from the mobilization of proliferating epithelial cells from residual prostate tissue under the wound. The proliferating cells expressed CK14, CK5, but not CK18, Syn, and CgA and re-epithelialize expressed uroplakin since 3 weeks. There were enhanced TGF-β1 and TGF-β type II receptor expression in proliferating cells and regenerated cells, which correlated with specific phases of re-epithelialization. Compared with the re-epithelialization of the bladder neck, re-epithelialization of canine prostatic urethra was faster, and the expression of collagen fibers was relatively low. In conclusion, re-epithelialization in canine prostatic urethra resulted from prostate basal cells after TmLRP and this re-epithelialization way may represent the ideal healing method from anatomic repair to functional recovery after injury.

Abstract
Chronic allograft nephropathy (CAN) is a major cause of graft loss following kidney transplantation and may result from the interactions of various immune and non-immune factors. The aim of the present study was to establish an in vitro model of glomerular mesangial cell injury in order to examine the gene expression levels of indoleamine 2,3-dioxygenase (IDO), heme oxygenase-1 (HO-1) and interleukin-7 (IL-7) in mesangial cells during the healing process as well as to investigate the effects of various immunosuppressants on the expression of these genes. The HBZY-1 glomerular mesangial cell line was pre-treated in vitro with cytochalasin B for 2 h to induce reversible damage. Following the pre-treatment, the HBZY-1 cells were divided into five groups: Blank control group, cyclosporine A (CsA) group, tacrolimus (Tac) group, mycophenolate mofetil (MMF) group and rapamycin (RAPA) group. After treating the mesangial cells with each immunosuppressive drug for 6, 12 or 24 h, the mRNA and protein expression levels of IDO, HO-1 and IL-7 were examined using reverse transcription quantitative polymerase chain reaction (RT-qPCR), western blot and immunohistochemical analyses. The results showed that expression levels of HO-1 were significantly upregulated in response to treatment with CsA, FK506, RAPA and MMF, whereas the expression levels of IL-7 were markedly downregulated by treatment with the above immunosuppressants. CsA, FK506 and MMF significantly enhanced the expression levels of IDO, whereas RAPA exhibited no apparent effect on IDO. The present study may contribute to the understanding of the pathogenesis of CAN and provide novel strategies for the prevention and treatment of CAN.

Abstract
AIM To take a deeper insight into the relationship between the root of the inferior mesenteric artery (IMA) and the autonomic nerve plexuses around it by cadaveric anatomy and explore anatomical evidence of autonomic nerve preservation in high ligation of the IMA in laparoscopic surgery for colorectal cancer. METHODS Anatomical dissection was performed on 11 formalin-fixed cadavers and 12 fresh cadavers. Anatomical evidence-based autonomic nerve preservation in high ligation of the IMA was performed in 22 laparoscopic curative resections of colorectal cancer. RESULTS As the upward continuation of the presacral nerves, the bilateral trunks of SHP had close but different relationships with the root of the IMA. The right trunk of SHP ran relatively far away from the root of IMA. When the apical lymph nodes were dissected close to the root of the IMA along the fascia space in front of the anterior renal fascia, the right trunk of SHP could be kept in suit under the anterior renal fascia. The left descending branches to SHP constituted a natural and constant anatomical landmark of the relationship between the root of IMA and the left autonomic nerves. Proximal to this, the left autonomic nerves surrounded the root of the IMA. Distally, the left trunk of the SHP departed from the root of IMA under the anterior renal fascia. When high ligation of the IMA was performed distal to it, the left trunk of SHP could be preserved. The distance between the left descending branches to SHP and the origin of IMA varied widely from 1.3 cm to 2.3 cm. CONCLUSIONS The divergences of the bilateral autonomic nerve preservation around the root of the IMA may contribute to provide anatomical evidence for more precise evaluation of the optimal position of high ligation of the IMA in the future.

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
The purpose of the current ex vivo study was to compare the speed of vaporesection of human prostatic tissue with benign prostatic hyperplasia (BPH) and the depth of tissue damage using 70- and 120-W 2-µm laser devices. Fresh prostatic tissue specimens were obtained from five patients by open prostatectomy, and were divided into separate groups (70 and 120 W) based on the energy of the laser output (70 and 120 W, respectively). The vaporesection speed, coagulation zone depth and the necrotic tissue layer in the prostatic tissue were evaluated. The current result showed that the speeds (mean±s.d.) of vaporesection were 5.21 ± 0.66 and 10.39 ± 1.15 g/5 min for the 70 and 120 W groups, respectively (P=0.000). There was no difference in the depth of necrosis/coagulation (0.98 ± 0.13/0.30 ± 0.09 and 0.99 ± 0.12/0.31 ± 0.08 mm) for the 70 and 120 W groups, respectively. In conclusion, both 70- and 120-W 2-µm laser devices had superficial tissue damage during the vaporesection of human prostate tissue; moreover, the 120-W laser offers a higher vaporesection speed than the 70-W laser.

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.
