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.

Objective To revise the Chinese version of the National Institutes of Health-Chronic Prostatitis Symptom Index (CHN-NIH-CPSD), and evaluate its feasibility, reliability, validity and responsiveness. Methods The NIH-CPSI was translated into Chinese according to a standard methodology including forward-backward-forward technique. The CHN-NIH-CPSI was pre-tested in consecutive samples of 162 native-speaking Chinese chronic prostatitis(CP)patients. Ninety-five of 162 filled the index again on the same day and after 4-week therapy. Ninety-seven healthy men were included as evaluated. Results The recovery of the questionnaires was 100% and all the patients filled the index completely. The mean time to complete the questionnaire for the patient group was 5.2±2.4 (range 2 - 12) min. The split-half reliability was 0.82. For the overall index and each subscale, the test-retest reliability was 0.98, 0. 98, 0. 98, 0. 97, respectively(P<0.01);and the Cronbach's α coefficient was 0. 61,0. 71, 0. 59, 0. 75, respectively. The confirmatory factor analysis showed good construct validity with a goodness of fit index of 0. 85 and a x2 of 124.67(P<0. 01). Of all 162 patients, the scores of the overall index and each subscale were 23. 33±5.91. 8. 80±4.26, 5.30±2.82, 9. 23±1.90, respectively;and those of healthy controls were 1. 95±1.97, 0. 37±1.03, 0. 15±0.58, 1.42± 1.20,respectively. Of the 95 patients, the original scores were 23. 53±5.60, 9.21 ±4.04, 5.10±2.75,9.21 ±2.05, comparing with 19.47±6.36, 7.79±3.95, 3. 58±1.88, 8.11±2.50, the 4 weeks later scores. The group t-test and paired t-test showed good responsiveness. Conclusions The CHN-NIH-CPSI has high feasibility, reliability, validity and responsiveness for testing the patients with CP. It is suitable for Chinese-speaking patients and helpful for cross-cultural comparisons of men with CP in clinical and research settings.

Objective To evaluate the advantages and disadvantages of various methods for the treatment of aortic dissection involving aortic arch. Methods The clinical data of 56 patients with aortic dissection involving aortic arch were analyzed retrospectively. All the patients were treated with throacic endovascular aortic repair (TEVAR) combined with chimney technique and hybrid operation to reconstruct partial vessels of the aortic arch according to the different morphology sites of aortic disease. Results Among 56 patients, 29 cases received TEVAR combined with chimney technique of left subclavian artery, and 27 cases received TEVAR combined with hybrid operation. Six cases had typeⅠendoleak. Among them, 2 cases improved by compliant balloon dilatation, and 4 cases were not treated. There was no death in perioperative period. The patients were followed up for 3-70 (22 ± 3) months, and all the branches of the artery were unobstructed during middle and long term follow-up. Conclusions Combined endovascular treatment is a safe and effective method for aortic dissection involving the aortic arch. In the meantime, strict preoperative evaluation and suitable operation method is also important.

Objective To investigate the changes of 4 histamine receptors (H1R, H2R, H2R and H4 R)in interstitial cystitis on animal experimental models. Methods Thirty female SD rats (250-300 g) were randomly divided into 2 groups as follows: 20 in experimental group and 10 in control group. The experimental group was filled with protamine sulfate+ potassium chloride to create interstitial cystitis model, the control group was sacrificed directly. At the end of the experiment, the bladders of all these SD rats were studied by the immunohistochemistry staining and the value of their mean absorbance (-A) was calculated by IPP4.5 image analysis software. The SPSS 11.5 was used to analyze the differences between the groups. Results Four kinds of histamine receptors mainly expressed in the bladder epithelium. In the experimental group, the (-A) of H1 R was 0. 054±0.031, the of H2R was 0.032±0.021, the (-A) of H3R was 0.047±0.033 and the (-A) of H4R was 0. 149±0. 191,respectively. In the control group, the A of H1R was 0. 017±0. 011, the (-A) of H2R was 0. 018±0. 015, the (-A) of H3R was 0. 014±0. 011, the (-A) of H4R was 0. 060±0.039, respectively. In contrast,the A of H1 R, H2 R and H3R in experimental group was increased significantly(P<0.05); there was no significant change in (-A) of H4R expression(P>0.05). Conclusions H1, H2 and H3 receptors in rat model interstitial cystitis bladder epithelium have increased and it indicates H1 R, H2R and H3R may be related to interstitial cystitis. H3 R may be a new treatment target of interstitial cystitis.
