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 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.

To retrospectively analyze the clinical data of 42 patients at our department with bulbar myasthenia gravis.They underwent video-assisted thoracoscopic extended thymectomy (VATET) from May 2003 to August 2010.Another 42 patients treated with medications alone were selected as controls.Compared with the control group (4.32 ± 0.23),postoperative dysphagia scores improved significantly in patients undergoing VATET(9.21 ±0.41).And so did the dysphagia assessment classification (P ＜0.05).Thus VATET could effectively and definitely relieve dysphagia in patients with bulbar myasthenia gravis.

Objective To evaluate the efficacy of Nebivolol on patients with mild or moderate essential hypertension(EH) using different methods of ambulatory blood pressure monitoring.Methods Forty-seven patients with mild or moderate EH were enrolled as our subjects after a 2-week administration of placebo.They were administrated Nebivolol (5 mg) once daily for 12 weeks.All the patients completed ambulatory blood pressure monitoring before and after taking Nebivolol for 12 weeks.The overall and individual methods were used to calculate the trough-to-peak ratio (T/P ratio) and smooth index (SI).Results (1) For all of 42 patients treated with Nebivolol (5 mg) for 12 weeks,the systolic blood pressure(SBP),diastolic blood pressure(DBP) of the whole-day,daytime and nighttime after treatment were decreased compared to before treatment (the whole day:(144.1 ± 9.8),(124.4 ± 10.4) mmHg vs.(93.2 ± 6.3),(79.2 ± 7.2) mmHg;daytime:(148.9 ± 9.7),(128.3 ± 10.5) mmHg vs.(96.8 ±6.1),(82.2 ±7.5) mmHg;nighttime:(133.9 ± 11.9),(115.9 ± 12.0) mmHg vs.(85.7 ± 8.0),(72.5 ± 7.5) mmHg),and there was significant difference (t =8.06,8.74,8.00,8.82,5.75,and 6.57 respectively; P ＜ 0.01).T/P ratios of SBP/DBP calculated by overall method were 78.4％ (17.4/22.2) and 61.2％ (9.0/14.7),but it were (79.3 ±0.4) ％ and (58.5 ±0.5) ％ by individual calculation method.(2) Among 30 patients with better effect,the SBP,DBP of the whole-day,daytime and nighttime after treatment were decreased compared to before treatment (the whole day:(143.4 ± 9.1),(127.5 ±10.7) mmHgvs.(92.6 ±6.2),(81.6±7.6) mmHg;daytime:(147.8 ±9.1),(131.0 ±10.5)mmHg vs.(95.8 ± 6.4),(84.1 ± 7.5) mmHg; nighttime:(134.7 ± 11.6),(119.6 ± 13.2) mmHg vs.(86.2 ± 7.4),(75.2 ± 8.5) mmHg),and there was significant difference(t =11.18,12.77,11.14,12.85,7.37,and 8.74 respectively,P ＜0.01).T/P ratios of SBP/DBP were 78.9％ (18.3/23.2),75.3％ (11.6/15.4) and SIof SBP/DBP were 7.4(19.5/2.6),7.1 (14.2/2.0) calculated by overall method,but T/P ratios of SBP/DBPwere (78.4 ± 0.4) ％,(74.6 ± 0.4) ％ and SI were (1.35 ± 0.73),(1.34 ± 0.54) calculated by individualmethod.Conclusion Nebivolol (5 mg once daily) can significantly reduce ambulatory blood pressure.Overall calculation method is better than individual method in terms of assessing the time of durative action and smooth effect by trough peak ratio and smooth index.
