PURPOSE 10 cases of testicle embryonal rhabdomyosarcoma (RMS) were treated in the Cancer Hospital of Shanghai Medical University from 1971 to 1988. All cases were treated by orchiectomy followed by retroperitoneal node dissection and three of them did not have lymph node metastases. Methods 2 cases were given postoperative irradiation, 7 cases received adjuvant chemotherapy. Results The 2-. 5-year overall survival were 50% and 30% respectively. Conclusion This report analyzes the prognosis of adult testicle embryonal rhabdomyosarcoma. The treatment is a combination of surgery、 chemotherapy and radiotherapy. Intensive chemotherapy should be administered. The prognosis of RMS in adult seems to be worse than in childhood. Patients with negative lymph nodes has better outcome than those with node metastases. Retroperitoneal lymph node dissection after radical inguinal orchiectomy is unnecessary in patients without CT evidence of nodal involvement.

Objective To investigate the bid gene expression and cell death in brain after cerebral hypoxia-ischemia in neonatal rats and the effects of dexamethasone(DEX)on bid gene expression,so as to elucidate the possible mechanism of the neuroprotective effect of DEX pretreatment on rats following cerebral hypoxia-ischemia.Methods Twenty-four SD neonatal rats were divided randomly into hypoxia-ischemia brain damage(HIBD),normal,dexamethasone-pretreated and 9 g/L NaCl(NS)control group.The animal models of HIBD were made.Total RNA from ipsilateral cerebral hemisphere was extracted.Reverse transcription polymerase chain reaction(RT-PCR)was used to evaluate the level of bid gene expression after hypoxia-ischemia.Cerebral apoptosis was determined by terminal-deoxynucleotidy transferase mediated d-UTP nick end labeling(TUNEL).Results The levels of bid mRNA were higher in HIBD rats than those in normal rats.The number of positive apoptosis cells significantly increased in HIBD group(P

Objective To explore the cellular inhibitor of apoptosis protein 1(cIAP1)gene expression and Caspase-3 activity in brain after cerebral hypoxia-ischemia in neonatal rats and the influence of dexamethasone(DEX)on cIAP1 gene expression and Caspase-3 activity,so as to elucidate the possible mechanism of the neuro-protective effect of DEX pretreatment on rats following cerebral hypoxia-ischemia.Methods Twenty-four SD neonatal rats were divided randomly into hypoxic-ischemic brain damage group(HIBD group),normal group(NS group),dexamethasone-pretreated group(DEX group)and 9 g/L NaCl control group(NS group).The animal models of HIBD were made.Total RNA from ipsilateral cerebral hemisphere was extracted.Reverse transcription polymerase chain reaction(RT-PCR)was used to evaluate the level of cIAP1 gene expression after hypoxia-ischemia.Caspase-3 relative activity of brain tissue was determined by colorimetric assay.Results The levels of cIAP1 mRNA were lower in HIBD group than those in NS group.Caspase-3 relative activity significantly increased in HIBD group(P

Objective:To'synthesize BODIPY-FL-labeled phenylephrine(BODIPY-FL-PE)and deter-mine its biological activity.Methods:Condensation of BODIPY-FL(green fluorescence dye)and phe-nylephrine(?_1-adrenoceptor agonist)was performed by adding dicyclohexylcarbodiimide(DCC)in thepresence of absolute tetrahydrofuran(THF).The reaction occurred in absolutely oxygen and water condi-tion at room temperature.The crude product was separated and purified by thin-layer chromatography(TLC).The structure of BODIPY-FL-PE was characterized by TLC and mass spectrometry(MS).Itspharmabiological activity was determined by Western blot.Results:BODIPY-FL-PE,the target mole-cule,was synthesized and its structure was identified by using ultra-violet spectrometry(UV)and MS.The result of Western blot indicated that ?_1-adrenoceptor(?_1-AR)induced ERK phosphorylation wasconfirmed in both BODIPY-FL-PE and PE treated groups.Conclusion:The synthesized BODIPY-FL-PEhas pharmacological activity that could activate ?_1-AR.Visualization of AR behaviors could be achievedby tracing the trajectories of BODIPY-FL-PE labeled AR.It might be a promising tool for investigatingdynamic behaviors of AR in living cells.
