Objective To investigate the monocyte chemoattractant protein (MCP1) gene expression of the bladder urothelial carcinoma and its correlation with the pathogenesis of the bladder urothelial carcinoma.Methods Thirty cases of patients with the bladder urothelial carcinoma, including 20 cases of male and 10cases of female, were taken the blood and bladder tissue.In control group, 30 cases of non-cancer patients,including 20 cases of male and 10 cases of female, were taken the blood samples.ELISA method was used to detected the concentration of plasma MCP1, immunohistochemical method to investigate the expression of MCP1 in the bladder urothelial carcinoma and adjacent tissues.Real-time quantitative RT-PCR was applied to detected the expression of MCP1. Data of the two groups were comparied and the relationship between the expression of MCP1 and the clinical characteristics of the bladder urothelial carcinoma was analyzed.Results MCP1 in group of patients with the bladder urothelial carcinoma was (193.4±105.7) pg/ml, and higher than that in non-tumor group (91.8±34.6) pg/ml (t = 8.37, P <0.001).MCP1 in invasive bladder cancer was (204.3±167.5) pg/ml and superficial bladder cancer was (130.6±69.2) pg/ml (t = 2.667, P = 0.013). By immunohistochemistry, the MCP-1 positive rate in the bladder urothelial carcinoma was 70.0 % (21/30), that in adjacent cancer tissue was 43.3 % (13/30) (χ2 = 4.9, P <0.05). The positive rate of MCP1 in invasive bladder cancer in tumor group was 80.0 % (8/10) and that in superficial bladder cancer was 65.0 %(13/20).At the same time, MCP- 1 positive intensity in the bladder urothelial carcinoma was significantly higher than that in adjacent tissues. The intensity in invasive bladder cancer was higher than that in superficial ones. Total RNA and mRNA levels of MCP-1 in the bladder urothelial carcinoma were statistically differences compared with that in adjacent tissues (χ2 = 10.08, P <0.05).Conclusion The upregulation of MCP1 gene expression is likely to play an important role in the incidence and metastasis of the bladder urothelial carcinoma.

Objective To study the expression of substance P(SP) and substance P receptor(SPR) during the development of mice brains. Methods The expression of SP and SPR during the development of mice brains from embryonic day(E) 11 to postnatal day(P) 0 days was analyzed by immunohistochemical method. Results The expression of SP began at E11 and gradually increased until birth. The expression of SPR began at E11 and maintained stable expression until birth. SP mostly expressed at striatum and SPR mostly expressed at medullary raphe.Conclusion The expression of SP and SPR during the embryo brain stage may indicate that SP could be an important factor involved in the early organization and maturation of neuron.

Objective To establish a less-damage method for tracheal intubation so as to improve the quality of post-cardiac arrest syndrome.Methods Thirty rabbits wvere divided into 3 groups of 10 rabbits each according to the random number table:group A receiving direct endotracheal intubation after anesthesia,Group B separation of cervical tissue and retrograde tracheal intubation after anesthesia and Group C percutaneous retrograde tracheal intubation after anesthesia.After the intravenous injection of forskolin,cardiac arrest was induced by endotracheal tube clamping.After 5 minutes of untreated arrest,conventional cardiopulmonary resuscitation was initiated.Changes in arterial pressure,occurrence of post-resuscition syndrome and survival time were examined in all groups.Results Groups A,B and C showed 40%,60% and 80% success rate in cardiopulmonary resuscitation (P < 0.01) and animal survival time of 23.4 hours (11.6-35.8 hours),62.7 hours (29.4-88.6 hours) and 79.5 hours (40.9-118.2 hours) (P < 0.01).Conclusions Percutaneous retrograde tracheal intubation is suitable to increase cardiopulmonary resuscitation rate and survival rate in rabbits with post-cardiac arrest.The model has good stability and repeatability and can be used for study of post-cardiac arrest syndrome.

Objective To investigate the effect of lipoxin A4 LXA4) on radicular pain caused by intervertebral disc herniation.Methods Non-compressive intervertebral disc herniation was induced into forty-eight adult male Sprague-Dawley rats,and they were divided into a sham group (sham operation + 10 μl normal saline),a control group (modeled + 10 μl normal saline),an LXA4 10 ng group (modeled + 10 ng LXA4) and an LXA4 100 ng group (modeled + 100 ng LXA4),with 12 rats in each group.The normal saline (10 μl) or LXA4 (10 μl) was administered intrathecally right after the operation and on each of the three succeeding days.General behavior was observed and the 50% paw withdrawal threshold (50% PWT) was measured.On postoperative day 7 all the rats were killed and the ipsilateral lumbar (L4~) segments of their spinal dorsal horns were removed for determination of the expression of p-JNK,t-JNK,p-ERK and t-ERK proteins using western blotting.TNF-α,IL-1β and TGF-β1 expression were determined using ELISA.Results There was no significant difference in the 50%PWT of the sham group before and after surgery,but the 50% PWTs of the control group and the LXA4 10 ng group were significantly decreased after the operation compared with their values beforehand and significantly lower than the value of the sham group at all time points.Moreover,the 50% PWT of the LXA4 10 ng group on postoperative days 3 and 5 was significantly higher than the control group;as was the value of the LXA4 100 ng group on postoperative days 2,3,4,5,6 and 7.The p-JNK and p-ERK expression in the control group,the LXA4 10 ng group and the LXA4 100 ng group were all increased significantly more than in the sham group,but their expression in the LXA4 10 ng group and LXA4 100 ng group were decreased significantly more in a dose-dependent manner compared with the control group,with the LXA4 100 ng group showing the greatest decrease.There were no significant differences in t-JNK or t-ERK expression within each group.Conclusion LXA4 can alleviate radicular pain caused by non-compressive lumbar intervertebral disc herniation.The underlying mechanism involves inhibiting the activation of the ERK and JNK pathways,reducing the expression of pro-inflammatory cytokines and increasing the expression of anti-inflammatory cytokines.
