AIM: The distribution of endothelin-1(ET-1) in uterine tube and its source were investigated in order to find out relation between endothelin-1 and function of uterine tube.METHODS: The distribution of endothelin-1 and the expression of ET-1 mRNA in the rabbits uterine tubes were studied using SABC immunohistochemistry and in situ hybridization histochemistry with digoxigenin-labelled rat ET-1 cRNA probe. RESULTS: ET-1 granules with red color were seen in the uterine tube epithelial cells and they were located mainly above the cell nucleus and under the cell surface membrane. Less ET-1 granules were seen in the myometrium of uterine tube. ET-1 mRNA positive hybridization signals with deep blue were distributed in the uterine tube epithelial cells. These signals were strong and dense. They were distributed mainly above the nucleus and near the cell surface membrane. ET-1 mRNA positive hybridization signal was not seen in the myometrium of uterine tube.CONCLUSION: Our results indicate that epithelial cells of rabbit's uterine tube epithelial cells secrete ET-1.

OBJECTIVE: To discuss whether a reduced dose of CsA was allowed yet without increase risk of rejection, and whether the incidence of CsA-related side effects be reduced while the curative effects be enhanced by combined use of Cyclosporine (CsA), prednisone and Mycophenolate Mofetil (MMF) in patients after renal transplantation. METHODS: In this comparative study, 213 renal allograft recipients receiving routine dose of CsA were compared with 176 cases receiving low dose CsA. RESULTS: The two groups showed no significant differences in renal function, incidence of rejection and human/kidney survival rate. However, the low dose CsA group showed a better total curative efficacy and significantly fewer incidences of ADRs. CONCLUSION: CsA, MMF and Pred used concomitantly in patients after renal transplantation allows for a reduced dose of CsA yet without increase the risk of acute rejection if with enough dose of MMF.

Objective To retrospectively compare the safety and local efficacy of multiple-electrode switching based radiofrequency ablation (RFA) and the conventional RFA in treating single early-stage hepatocellular carcinoma (HCC).Methods A total of 82 patients with single early-stage HCC received either RFA with a multiple-electrode switching system (n =43) or conventional RFA (n =39) as the first-line treatment.The rate of initial local complete response,major complications and local tumor progression (LTP) were compared between two groups.Results The total ablation time was significantly shorter in the switching-RFA group [(16.7 ± 3.4) mins] than in the conventional RFA group [(29.8 ± 10.4) mins] (P ＜ 0.05).The rate of initial local complete response was 100％ (43/43) in the switching-RFA group and 94.9％ (37/39) in the conventional RFA group (P ＞0.05).After a mean follow-up period of (26.4 ± 21.8)months (ranging 3.0-91.6 months),the rates of LTP in the switching-RFA group and conventional RFA group were 16.3％ (7/43) and 17.9％ (7/39),respectively.The LTP rates in two groups were 16.1％ versus 11.2％ atyear1,and20.5％ versus 20.6％ at year2 (P=0.666).Conclusions The multiple-electrode switching based RFA is safe and effective with shorter ablation time in treating single early-stage hepatocellular carcinoma.

In this study, the expressions of growth hormone secretagogue receptor type 1a (GHS-R1a) in the rat dorsal root ganglion (DRG) and nodose ganglion (NG) were investigated by using immunohistochemistry and in situ hybridization. The results clearly showed the presence of GHS-R1a mRNA and GHS-R1a-positive neurons in the rat DRG and NG. GHS-R1a was also co-localized with calcitonin gene-related peptide (CGRP) in some DRG and NG neurons, indicating the existence of subpopulations of the visceral afferents. The extrinsic primary afferent visceroceptive DRG and NG neurons from the stomach were identified by retrograde tracing fluorogold and stained for GHS-R1a and CGRP. Some neurons both positive for CGRP and GHS-Rla were labled by fluorogold. Our results not only demonstrate the expression of GHS-R1a in the vagal afferents but also provide the first and direct morphological evidence for its presence in the spinal visceral afferents, and gherin might have a modulatory role in the visceral afferent signaling.

OBJECTIVETo investigate the influence of Kudou Shencha decotion on INF-y, ICAM-1, MCP-1 levels of prostate tissue homogenate in immunity prostatitis model rats.

METHODForty Wistar male rats were divided into 5 groups randomly: Kudou Shencha decotion group with high dosage and low dosage, Qianleitai group, the model control group and normal group. The rat model of chronic nonbacterial prostatitis was established by multiple hypodermical injection of the suspension of prostatic protein purification with Freund's completed adjuvant. The level of intercellular adhesion molecule (ICAM-1), interferon gamma (INF-gamma) and monocyte chemotactic protein-1 (MCP-1) were measured by enzyme linked immunosorbent assay (ELISA).

RESULTThe content of ICAM-1 and MCP-1 in the model group was higher than that of the normal group (P < 0.05), the content of ICAM-1 was obviously decreased in Kudou Shencha decotion group with high dosage (P <0.05), the contents of MCP-1 were all obviously decreased in Kudou Shencha decotion groups and Qianlietai group. Compared with the model group, the contents of INF-gamma in all treatment groups were decreased insignificantly.

CONCLUSIONKudou Shencha decotion has the action of lowering the level of ICAM-1 and MCP-1, which may be one of the mechanisms of Kudou Shencha decotion in the therapy of chronic prostatitis.
