BACKGROUND@#The optimal treatment for large impacted proximal ureteral stones remains controversial. The aim of this study was to evaluate the efficacy, safety, and potential complications of mini-percutaneous nephrolithotomy (MPCNL) and retroperitoneal laparoscopic ureterolithotomy (RPLU) in the treatment of impacted proximal ureteral stones with size greater than 15 mm.@*METHODS@#A total of 268 patients with impacted proximal ureteral stones greater than 15 mm who received MPCNL or RPLU procedures were enrolled consecutively between January 2014 and January 2019. Data on surgical outcomes and complications were collected and analyzed.@*RESULTS@#Demographic and ureteral stone characteristics found between these two groups were not significantly different. The surgical success rate (139/142, 97.9% vs. 121/126, 96.0%, P = 0.595) and stone-free rate after 1 month (139/142, 97.9% vs. 119/126, 94.4%, P = 0.245) of RPLU group were marginally higher than that of the MPCNL group, but there was no significant difference. There was no significant difference in the drop of hemoglobin between the two groups (0.8 ± 0.6 vs. 0.4 ± 0. 2 g/dL, P = 0.621). The mean operative time (68.2 ± 12.5 vs. 87.2 ± 16.8 min, P = 0.041), post-operative analgesics usage (2/121, 1.7% vs. 13/139, 9.4%, P = 0.017), length of hospital stay after surgery (2.2 ± 0.6 vs. 4.8 ± 0.9 days, P < 0.001), double J stent time (3.2 ± 0.5 vs. 3.9 ± 0.8 days, P = 0.027), time of catheterization (1.1 ± 0.3 vs. 3.5 ± 0.5 days, P < 0.001), and time of drainage tube (2.3 ± 0.3 vs. 4.6 ± 0.6 days, P < 0.001) of MPCNL group were significantly shorter than that of the RPLU group. The complication rate was similar between the two groups (20/121, 16.5% vs. 31/139, 22.3%, P = 0.242).@*CONCLUSIONS@#MPCNL and RPLU have similar surgical success and stone clearance in treating impacted proximal ureteral stones greater than 15 mm, while patients undergoing MPCNL had a lower post-operative pain rate and a faster recovery.

OBJECTIVE@#To investigate the serum level of soluble transferrin receptor (sTfR) and its association with the degree of anemia in children with hemoglobin H (HbH) disease.@*METHODS@#A total of 55 children with HbH disease were enrolled as the HbH group, and 30 healthy children were enrolled as the control group. The HbH group was further divided into a deletional HbH disease group and a non-deletional HbH disease group. A retrospective analysis was performed for hematological parameters and serum sTfR level in all groups.@*RESULTS@#Of the 55 children with HbH disease, 39 had deletional HbH disease and 16 had non-deletional HbH disease. Compared with the control group, the deletional and non-deletional HbH disease groups had significantly lower hemoglobin (Hb), mean corpuscular volume (MCV), and mean corpuscular hemoglobin (MCH) and a significantly higher serum level of sTfR. Compared with the deletional HbH disease group, the non-deletional HbH disease group had significantly lower red blood cell count (RBC) and Hb level and significantly higher MCV, MCH, and serum sTfR level. In children with HbH disease, serum sTfR level was negatively correlated with RBC and Hb level (r=-0.739 and -0.667 respectively, P<0.05) and positively correlated with MCV and MCH (r=0.750 and 0.434 respectively, P<0.05).@*CONCLUSIONS@#Serum sTfR level is associated the degree of anemia in children with HbH disease, and sTfR may be a target for the treatment of HbH disease.

<p><b>OBJECTIVE</b>To explore the molecular mechanism of pain associated with chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) in the rat model of prostatic inflammation.</p><p><b>METHODS</b>Thirty-six male SD rats were equally randomized to an experimental and a control group, the former injected with 50 μl of 3% λ-carrageenan into the ventral prostate to make the model of non-bacterial prostatic inflammation, while the latter with the same volume of sterile saline solution. At 1, 2 and 4 weeks after modeling, the prostate, L6-S1 dorsal root ganglion (DRG) and spinal cord were harvested for examination of the expressions of the nerve growth factor (NGF), transient receptor potential ankyrin 1 (TRPA1), and calcitonin-gene-related peptide (CGRP) by immunohistochemistry and Western blot.</p><p><b>RESULTS</b>The expressions of NGF, TRPA1 and CGRP in the prostatic tissue were all significantly increased in the experimental group as compared with the control (P <0.05), with a gradual decrease with the prolonging of time (P <0.05). In the L6-S1 DRG and spinal cord, the expressions of NGF, TRPA1 and CGRP exhibited no significant differences between the experimental and control groups at 1 week after modeling (P >0.05) and kept at high levels in the experimental group at 2 and 4 weeks, though not significantly different from those at 1 week (P >0.05). Statistically significant differences were observed in the expressions of the three proteins in the experimental rats among different time points (P <0.05), but not between the two groups at any time point (P >0.05).</p><p><b>CONCLUSION</b>The molecular mechanism of CP/CPPS can be evaluated in the rat model of prostatic inflammation established by injecting λ-carrageenan into the prostate. TRPA1 may play an important role in connecting the upstream and down-stream pathways of CP/CPPS-associated pain.</p>

<p><b>OBJECTIVE</b>To search for an effective hormonal therapy for delaying the progression of prostate cancer to androgen-independent prostate cancer (AIPC).</p><p><b>METHODS</b>This study included 93 cases of prostate cancer confirmed by transrectal ultrasound-guided biopsy, 22 treated by bilateral orchiectomy plus bicalutamide as a continuous androgen deprivation (CAD) therapy, and the other 71 by the intermittent androgen deprivation (IAD) therapy, the latter divided into a standard IAD group (n = 29) and a modified IAD group (n = 42) to be treated by maximum androgen blockage (MAB) until the serum PSA level decreased to less than 0.2 microg/L and the medication was maintained for 3 months. Entering the intermittent period, the patients of the standard IAD group discontinued medication, while those in the modified IAD group withdrew luteinizing hormone-releasing hormone analogue (LHRH-a) but continued the use of bicalutamide. MAB was resumed in these two groups when serum PSA manifested a continuous rise and went up to 4 microg/L until prostate cancer progressed to AIPC. Comparisons were made among the CAD, standard IAD and modified IAD groups in the follow-up time, time of progression to CRPC and treatment cycles.</p><p><b>RESULTS</b>The three groups of patients were well balanced in terms of demographics, baseline characteristics and follow-up time. The median times of progression to AIPC in the CAD, standard IAD and modified IAD groups were (26.50 +/- 4.15), (30.00 +/- 7.83) and (34.93 +/- 5.08) months, respectively, with statistically significant differences between the modified IAD group and the CAD (P = 0.001) and standard IAD (P = 0.032), but not between the latter two groups (P = 0.143). Kaplan-Meier survival curves showed a significantly longer median time of progression to AIPC in the modified than in the standard IAD group (P = 0.01). The mean cycle length was (16.13 +/- 3.33) months for the standard IAD group and (19.58 +/- 4.30) months for the modified IAD group, and the time off treatment of the first cycle was (9.6 +/- 3.2) months in the former and (14.2 +/- 3.7) months in the latter, with significant difference between the two groups (P = 0.001).</p><p><b>CONCLUSION</b>Compared with CAD and standard IAD, modified IAD therapy can significantly prolong the time of progression to AIPC in patients with prostate cancer.</p>

<p><b>OBJECTIVE</b>To study association of uridine-diphosphate-glucuronosyltransferase1A1 (UGT1A1) Gly71Arg, UGT1A1 promoter TATA-box and glucose-6-phosphate dehydrogenase (G6PD) gene mutations with the occurrence of neonatal unconjugated hyperbilirubinemia.</p><p><b>METHODS</b>The TATA-box, exon 1 and exon 5 of the UGT1A1 gene and the exon 12 of G6PD gene were amplified by PCR. The products of PCR were analyzed by direct DNA sequencing. Clones for the mutations of the UGT1A1 gene and the G6PD gene were constructed in order to identify the results of the products of PCR. Seventy-two neonates with unconjugated hyperbilirubinemia (case group) and 65 healthy neonates (control group) were enrolled. The genotypes and allele frequencies of the polymorphisms of UGT1A1 Gly71Arg and UGT1A1 TATA-box were compared between the two groups. The effects of UGT1A1 Gly71Arg, UGT1A1 promoter TATA-box and G6PD gene mutations on the development of neonatal unconjugated hyperbilirubinemia were estimated using logistic regression models.</p><p><b>RESULTS</b>There were significant differences in the genotype distribution of Gly71Arg polymorphism of UGT1A1 gene between the case and control groups (P<0.01). The Arg allele frequency of the polymorphisms of UGT1A1 gene in the case group was significantly higher than in the control group (P<0.01). There were no significant differences in the genotype distribution of the UGT1A1 promoter TATA-box between the two groups (P>0.05). The OR and 95%CI values of UGT1A1 Gly71Arg, UGT1A1 TATA-box and G6PD gene mutations associated with the development of neonatal unconjugated hyperbilirubinemia were 5.468 (2.274, 12.818), 0.688 (0.266, 1.778) and 5.081 (1.070, 24.133) respectively.</p><p><b>CONCLUSIONS</b>UGT1A1 Gly71Arg and G6PD gene mutations may be involved in the development of neonatal unconjugated hyperbilirubinemia.</p>
