Intravesicular administration of sodium hyaluronate ameliorates the inflammation and cell proliferation of cystitis cystica et glandularis involving interleukin-6/JAK2/Stat3 signaling pathway.

Cystitis cystica et glandularis (CCEG) is a chronic cystitis that causes extreme agony in affected patients. However, there are lack of effective conservative treatments. In this study, it is evident that intravesicular sodium hyaluronate (SH) therapy significantly improved the clinical symptoms of CCEG patients and ameliorated the bladder mucosal inflammation and cell proliferation characteristics of the disease. Immunohistochemical staining showed that the staining intensities of hyaluronidase (HYAL 1/2), CD44, IL-6 and phosphorylated signal transducer and activator of transcription 3 (p-Stat3) in bladder mucosal tissue were significantly increased in CCEG patients compared with control patients and that intravesicular SH treatment suppressed these protein expression. We established a CCEG rat model by treating rats with E. coli intravesicularly, and we found that HYAL 1/2 and CD44 expression levels were significantly increased in the E. coli group compared with the NC group. Activation of the IL-6/JAK2/Stat3 pathway and the expression levels of the downstream pro-apoptotic proteins Mcl-1 and Bcl-xL were also significantly increased in the E. coli group compared with the NC group. The above changes were significantly mitigated by intravesicular SH treatment. Therefore, SH may serve as an effective therapy for CCEG by inhibiting bladder mucosal inflammation and proliferation.

[Benefit of post-circumcision application of skin wound induction gel in the treatment of phimosis in children].

OBJECTIVE: To study the effects of skin wound induction gel on the glans scabbing rate, class-A wound healing rate, and wound healing time of circumcision for phimosis in pediatric patients. METHODS: We randomly assigned 48 six to thirteen years old children with phimosis to an experimental group (n = 25) and a control group (n = 23) to be treated by circumcision. After surgery, the patients in the experimental group received application of skin wound induction gel while those in the control group received that of povidone iodine only to the glans and incision. We recorded and compared the glans scabbing rate, class-A wound healing rate, and wound healing time between the two groups of patients. RESULTS: Glans scabbing was observed in 3 cases in the experimental group and 17 cases in the control group (12.0% vs 73.9%, P < 0.01). No statistically significant differences were found in the rate of class-A wound healing between the two groups (100% vs 91.3%, P > 0.05). The wound healing time was significantly shorter in the experimental than in the control group ([10.7 ± 1.7] d vs [11.9 ± 2.1] d, P < 0.05). CONCLUSION: Post-circumcision application of skin wound induction gel to the glans and incision can effectively reduce glans secreta, alleviate inflammatory reaction, and shorten the healing time in the treatment of phimosis in children.
