Chinese Journal of Urology 2010;31(8):541-543
Objective To investigate the changes of histamine receptors in bladder before and after the treatment by sodium hyaluronate in rats of interstial cystitis (IC). Methods Twenty IC model rats were randomly divided into experimental group and control group, with 10 for each group.The bladders in experimental group were filled with sodium hyaluronate, while the rats in control group were executed at once. The bladders were dyed with HE staining, special staining and immunohistochemistry staining to count the number of mononuclear cells and mast cells and observe the changes of histamine receptors. Results In experimental group,the counts of mononuclear cells and mast cells were 12.20±2.48 and 2.90±0.87 respectively;the numbers of average optical of histamine receptor H1, H2, H3, H4 were 0.015±0.007, 0.006±0.001, 0.007±0.004, 0.061±0.026 , respectively. In control group, the counts of mononuclear cells and mast cells were 23.90±3.07 and 7.08±1.23;the numbers of average optical of histamine receptor H1, H2, H3, H4 were 0.055±0.033, 0.031±0.023, 0.033±0.017, 0.091±0.059, respectively. The differences of mononuclear cells and mast cells were significant between the 2 groups(P<0.01). The differences of average optical of histamine receptor H1, H2, H3 between the 2 group were significant (P<0.05), while the difference of histamine receptor H4 was not significant(P>0.05). Conclusion Histamine receptor H1, H2, H3 take part in the development of IC, the antagons may be used for the treament of IC.

OBJECTIVEWe used functional magnetic resonance imaging (fMRI) to explore the effects of noxious coldness and non-noxious warmth on the magnitude of cerebral cortex activation during intraoral stimulation with water.
METHODSSix male and female subjects were subjected to whole-brain fMRI during the phasic delivery of non-noxious hot (23 °C) and no- xious cold (4 °C) water intraoral stimulation. A block-design blood oxygenation level-dependent fMRI scan covering the entire brain was also carried out.
RESULTSThe activated cortical areas were as follows: left pre-/post-central gyrus, insula/operculum, anterior cingulate cortex (ACC), orbital frontal cortex (OFC), midbrain red nucleus, and thalamus. The activated cortical areas under cold condition were as follows: left occipital lobe, premotor cortex/Brodmann area (BA) 6, right motor language area BA44, lingual gyrus, parietal lobule (BA7, 40), and primary somatosensory cortex S I. Comparisons of the regional cerebral blood flow response magnitude were made among stereotactically concordant brain regions that showed significant responses under the two conditions of this study. Compared with non-noxious warmth, more regions were activated in noxious coldness, and the magnitude of activation in areas produced after non-noxious warm stimulation significantly increased. However, ACC only significantly increased the magnitude of activation under noxious coldness stimulation.
CONCLUSIONResults suggested that a similar network of regions was activated common to the perception of pain and no-pain produced by either non-noxious warmth or noxious coldness stimulation. Non-noxious warmth also activated more brain regions and significantly increased the response magnitude of cerebral-cortex activation compared with noxious coldness. Noxious coldness stimulation further significantly increased the magnitude of activation in ACC areas compared with noxious warmth.

Objective To investigate the effects of femoral nerve block combined with celecoxib on postoperative analgesia in elderly patients with hip fracture. Methods Two hundreds ASA -Ⅲ patients aged 65-89 yrweighing 35-90 kg undergoing hip fracture surgery were randomly divided into 4 groups ( n = 50 each):control group (group Ⅰ ), femoral nerve block group ( group Ⅱ ), celecoxib group (group Ⅲ ) and femoral nerve block +celecoxib group (group Ⅳ ). Operations were performed under combined spinal-epidural anesthesia. Groups Ⅲand Ⅳ were given oral celecoxib 400 mg at 1 h before operation, and 200 mg at 1 and 2 days after operation twice a day. Groups Ⅰ and Ⅲ received iv injection of sufentanil 0.06 μg/kg before the patients were placed in the position, while in groups Ⅱ and Ⅳ femoral nerve block was performed using a nerve stimulation with 20 ml of 0.5%ropivacaine and 10 min later the patients were placed in the position. All the patients received postoperative patient-controlled intravenous analgesia with sufentanil to maintain visual analogue scale score ≤ 3. The condition of satisfactory analgesia and sufentanil consumption within 24, 48 and 72 h were recorded. The coagulation function was measured on the day of admission to the hospital, at 1 day before operation and at 4 days after operation. Cardiac troponin Ⅰ (cTnI) concentrations were measured before operation, at the end of operation and at 1 day after operation. Postoperative complications was observed and recorded. Results Compared with group Ⅰ , the consumption of sufentanil was significantly reduced during each period in group Ⅳ ( P < 0.01 ). Compared with group Ⅱ , the consumption of sufentanil was significantly reduced within 48 and 72 h after operation (P < 0.05), while no significant change was found within 24 h after operation in group Ⅳ ( P > 0.05). Compared with group Ⅲ , the consumption of sufentanil was significantly reduced within 24 h after operation ( P < 0.05 ), while no significant change was found within 48 and 72 h in group Ⅳ ( P > 0.05). The level of satisfactory analgesia was significantly higher in group Ⅳ than in the other three groups, and in groups Ⅱ and Ⅲ than in group Ⅰ ( P < 0.05). The 4 groups were comparable with respect to the increased rate of cTnI concentrations at the end of operation and after operation, and perioperative blood coagulation. No postoperative complications were found in the 4 groups. Conclusion Femoral nerve block combined with celecoxib can reduce postoperative opioid consumption and enhance postoperative analgesia in elderly patients with hip fracture.

AIM: Aquaporins(AQP) are very important for the water transport across cell membrane. Aquaporin 7(AQP 7) and aquaporin 8(AQP8) expressed in the rat testis, but the biophysical functions of these two aquporins in testis and the regulatory mechanism of their expression remain unclear. The aim of this study was to find out if the expression of these two aquporins was correlative with the function of testis, and if panaxadiol saponins (PDS) affected their expression. METHODS: 4 weeks, 8 weeks and 12 weeks old rats were divided into saline and PDS injection groups. Semi-quantified RT-PCR method was employed to detect aquaporin 7 and 8 gene expression: using total RNA extracted from rat testis as PCR template, then using optical scanner to measure the OD value of bands on agrose electrophoresis. OD value of target gene products was divided by which of contol gene. The ratio was identified as the quantity of target gene expression. Western blot was also employed to detect expression of these two proteins in the testis. RESULTS: ①OD value of AQP 7 mRNA products in testis of 4 weeks, 8 weeks, 12 weeks rats were 48 227, 51 536, 59 567 respectively and the ratio divided by OD value of control gene was 0.82, 0.85, 0.99; OD value of AQP 8 mRNA products in testis of 4 weeks, 8 weeks, 12 weeks rats were 23 092, 39 302, 43 316 respectively, the ratio divided by OD value of control gene was 0.39, 0.65, 0.72. Thus, AQP 7 and 8 mRNA expression increased with age. ②After PDS injection for 2 weeks. AQP 7 and 8 mRNA expression in 4 weeks old rats increased to 0.97 and 0. 72,which in control group were 0. 82 and 0. 39; the ratio decreased to 0.77 and 0.55 in 8 weeks old rats, which in control group were 0.85 and 0.65. There was no PCR product of neither aquaporins in 12 weeks old PDS injected rats, except products of control gene. ③ Western blot of AQP 7 and 8 protein showed little difference between PDS and saline injected 12 weeks old rats. CONCLUSION: ①Quantity of AQP 7 and AQP 8 expression was related to testis function of rats. ②PDS influenced the expression of AQP 7 and AQP 8 mRNA, perhaps by promoting the secretion of LH in pituitary.
