ABSTRACT

Pediatric neurogenic bladder (PNB) is defined as dysfunction of the detrusor and/or urethral sphincter due to myelodysplasia or spinal cord injury, manifesting as impaired urination or defecation, which seriously affects the patients’ quality of life. The main indication for sacral neuromodulation (SNM) is overactive bladder syndrome, which presents as refractory urinary frequency and urgency, urgency incontinence and non-obstructive urinary retention. Age more than 16 years are also recommended for this technique. Previous studies have revealed that SNM could significantly improve the outcome of refractory bladder bowel dysfunction. This paper reviews the advances of the application of SNM in the treatment of pediatric neurogenic bladder so as to provide reference for pediatricians.

ABSTRACT

Objective:To investigate the effects of hydrogen rich-saline (HRS) on intestinal mucosal barrier in rat with intestinal ischemia/reperfusion injury (IIRI).Methods:Twenty-four healthy male Sprague-Dawley rats, aged 8 weeks, were randomly divided into 3 groups (8 in each group) by random number table method: sham group, model group and HRS group.Rats in HRS group were intraperitoneally injected with HRS (10 mL/kg) at 30 min of ischemia, and the same amount of normal saline was intraperitoneally injected in model group.After 45 min of ischemia and 6 h of reperfusion, rats were sacrificed.Serum and ileum were collected for further detection.Tumor necrosis factor alpha (TNF-α), interleukin (IL)- 1β and IL-17A expression levels in serum were detected by conducting enzyme-linked immunosorbent assay (ELISA). The localization expressions of tight junction protein Occludin was detected by immunohistochemical staining (IHC), while the localization expression of tight junction protein zonula occluden-1 (ZO-1) were detected by immunofluorescence staining (IF). The protein expression of Occludin, ZO-1, and Lysozyme were detected by performing Western blot.The mRNA expression of Lysozyme and α-defensin were detected by real-time PCR (qPCR).Results:ELISA results proved that the levels of serum TNF-α and IL-1β in HRS group rats were significantly lower than those in model group [(62.02±29.97) ng/L vs.(113.40±44.58) ng/L, (21.68±0.35) ng/L vs.(28.29±3.49) ng/L], while the level of IL-17A increased [(28.18±5.28) ng/L vs. (15.10±3.60) ng/L] (all P<0.05). IHC staining: compared with model group, the expression of Occludin in HRS group was uniform and continuous, and the staining was darker.IF results: compared with model group, the fluorescence signal intensity of ZO-1 in HRS group rats significantly increased, and the distribution was clear and continuous.Wes-tern blot results: compared with model group, the expression levels of Occludin and ZO-1 proteins in HRS group rats remarkably increased (0.79±0.06 vs. 0.54±0.04, 0.91±0.11 vs. 0.51±0.13), while Lysozyme protein decreased (1.50±0.40 vs. 2.99±0.80) (all P<0.05). qPCR results revealed that the expression level of Lysozyme mRNA in HRS group rats was lower than that in model group (1.64±0.33 vs. 2.20±0.40), while α-defensin mRNA obviously increased (0.82±0.19 vs. 0.47±0.13) (all P<0.01). Conclusions:HRS protects intestinal mucosal barrier by inhibiting the expression of tight junctions and the secretion of antimicrobial peptides in rat suffering from IIRI.

ABSTRACT

Objective To evaluate the effect of Chinese herbal medicine immunomodulator on T lymphocyte immune function in peripheral blood and intestinal mucosa of immature rats with obstructive jaundice. Methods Three-weeks Wistar rats were randomly divided into four groups. (n= 12, in each): normal control group, sham operation group, obstructive jaundice (OJ) group, OJ + Chinese herbal medicine immunomodulator (OJ+ZY) group. Except for the normal control group, the others' bile duct stones were ligatured to establish rat models with obstructive jaundice. The percentage of CD4+ and CD8+ tlymphocytes and the ratio of CD4+/CD8+ in peripheral blood and intestinal mucosa of immature rats was detected by flow cytometry. Results The percentage of CD4+ cell [(36.2 ±4.2)%, (28.8±1.8)% respectively] and the ratio of CD4+/CD8+ [(1.14±0.39), (1.37±0.34)respectively] in OJ group were lower than those in normal control group [peripheral blood: CD4+(41.5±5.3)%,CD4+/CD8+(1.37±0.19); intestinal mucosa: CD4+(32.3± 2.4)%, CD4+/CD8+ (1.84+0.28) and sham operation group (peripheral blood: CD4+ (41.2±5.5)%, CD4+/CD8+ (1.45±0.27); intestinal mucosa: CD4+(31.5 ± 2.7)%, CD4+/CD8+ (1.63±0.58)] . The difference was statistical significant(P<0.05). The percentage of CD4+ cell [(42.7±6.3)%, (33.6±2.4)% respectively] and the ratio of CD4+/CD8+ [(1.56±0.46), (1.84±0.56)respectively] in OJ+ZY group, were higher than those in OJ group(P<0.05). The difference was statistical significant(P<0.05). Conclusion Chinese herbal medicine immunomodulator can increase T lymphocyte immune function in immature rats with obstructive jaundice, but has no significance in normal control group as well as sham operation group.
