Objective To study the expression status of estrogen receptor-alpha36(ER-α36)in breast cancer tissue and its rela-tionships with the occurrence,development and clinical prognosis of breast cancer.Methods 653 cases of breast cancer tissues were selected in this study.The real-time reverse transcription polymerase chain reaction(RT-PCR)and immunohistochemistry were used to detect the expression of ER-α36,estrogen receptor-alpha66 (ER-α66),progesterone receptor(PR)and human epidermal growth factor receptor-2(Her-2).The relationships between the expression of ER-α36,ER-α66,PR and Her-2 and the pathological charac-ter were analyzed.Results The expression rate of ER-α36 in all cases was 40%.The expression rate of ER-α36 in Her-2 positive tissues(63%)was significantly higher than that in the Her-2 negative group(44%,P <0.05).The expression rate of ER-α36 in ER-α66/PR/Her-2 negative tissues(66%)was significantly higher than that in the non-three-negative group(35%,P <0.05).The differences of ER-α36 expression rate between ER-α66 positive samples and negative samples or between PR positive and negative samples showed no statistical significance(P >0.05).The expression rate of ER-α36 in stage Ⅲ+Ⅳ breast cancer tissues(54%) was significantly higher than that in stage Ⅰ+Ⅱ breast cancer tissues(28%,P <0.05).The expression rate of ER-α36 in breast cancer tissues with lymph node metastasis (55%)was significantly higher than that in breast cancer tissues without lymph node me-tastasis (23%,P <0.05).Conclusion The results indicate that ER-α36 may play a very important role in the occurrence,develop-ment and lymph node metastasis of breast cancer,and be associated with the expression of Her-2,breast cancer staging and lymph node metastasis.ER-α36 is expected to become a new tumor marker and clinical diagnosis and treatment target.

ObjectiveTo explore the damage of blood vessels in carbon monoxide poisoning patients by hyperbaric oxygen, especially for damage of vein, to understand the factors aggravating inflammatory response, thus work out the homologous protective measures.MethodsFrom January 2006 to January 2008, 80 patients of carbon monoxide poisoning were selected as the observation group. Another 80 patients with other diseases were set as the control group. Two groups both accepted hyperbaric oxygen treatment. The time of angioplerosis was compared between the two groups, besides, pain reaction of the observation group was also observed.ResultsThe time of angioplerosis was significantly different between the two groups, pain sensibility intensified in the observation group compared with that before treatment.ConclusionsHyperbaric therapy is closely related with vascular inflammatory reaction of carbon monoxide poisoning patients. Protective measures should be established in order to prevent further damage of vessel, relieve pain of patients and ensure smooth progress of the treatment.
