Objective To discuss the correlation of P-glycoprotein(P-gp) and lymphocyte subgroup(CD4+,CD8+) in patients with immune thrombocytopenia.Methods A total of 20 patients with immune thrombocytopenia were selected from August 2015 to September 2016 in the Eighth Hospital Affiliated to Sun Yat-sen University.According to the platelet count,all patients were divided into mild group and severe group,20 cases of health persons were selected at the same period as the healthy group,flow cytometry technique was used to detect the plasma lymphocyte subsets(CD4+,CD8+) and P-gp level of all the objects.Pearson correlation analysis was used to analyze the relationship between plasma P-gp and plasma CD4+,CD8+,CD4+ / CD8+ level,analyzed all the objects plasma platelet count,P-gp and CD4+,CD8+,CD4+ / CD8+ levels.Results Plasma CD4+,CD8+,CD4+ / CD8+ and P-gp level of severe group were significant higher than those of mild group(t=3.587,2.957,2.315,2.646,P<0.05),plasma CD4+,CD8+,CD4+ / CD8+ and P-gp level of mild group patients were significant higher than those of healthy group(t=5.479,2.921,4.536,7.750,P<0.05).Pearson correlation analysis results showed that the plasma levels of P-gp and plasma CD4+,CD8+,CD4+ / CD8+ levels were positively correlated(r=0.683,0.617,0.548,P<0.05).Conclusion Plasma CD4+,CD8+,CD4+/CD8+and P-gp level is associated with immune thrombocytopenia patients condition,plasma levels of P-gp closely links with abnormal immune function in patients with hyperthyroidism,prompting detection the level of change could help doctors to assess patients medication curative effect.

Objective To study the expression levels and its clinical significance of angiopoietin 2 (Ang-2) gene in acute lymphatic leukemia(ALL). Methods The qualitative detection method was established with SYBR Green Ⅰ by real-time fluorescent quantitative PCR, and Ang-2 mRNA was measured in 51 cases of pre-therapeutic ALL. In addition, the expression of Ang-2 gene was also analyzed in 20 cases of non-malignant hematological diseases. Results The expression of Ang-2 gene was found in all the patients, and Ang-2 expression level in ALL patients was significantly higher than that of the controls (P<0.05). No significant relationship was found between Ang-2 expression level and clinical characteristics (age, haematogloblin, WBC count, platelet count, LDH, blast cells in peripheral blood, blast cells in bone marrow). The expression level of Ang-2 have no effect on one year replase rate and survival rate in ALL. Conclusion Ang-2 expression level in ALL patients was higher than that in non-malignant hematological diseases, and there may be no relationship with clinical manifestation, treatment and prognosis.

Objective To evaluate the therapeutic effects and safety of acitretin for severe inherited keratodermas in children and adolescents. Methods Acitretin was given to 23 children and adolescents with either lamellar ichthyosis, bulbous ichthyosiform erythroderma, pityriasis rubra pillars, progressive sym- metrical erythrokeratoderma, keratitis ichthyosis deafness syndrome, generalized porokeratosis, inflammatory liner verrucous epidermal nevus, ichthyosis hystrix and non-bullous ichthyosiform erythroderma. The thera- peutic dosage was 0.67-1.07 mg/(kg?d),and maintenance dosage 0.08-0.94 mg/(kg?d).The effects on the patients' growth and development of the drug were evaluated based on the changes of body weight and height in the children. The total follow-up period was 6-35 months in an interval of 1-3 months. Results The considerable overall improvement was achieved after 1-6 months' treatment, with an overall clinical cure rate of 82.6%. Only one case responded poorly to the therapy. The excellent responses were observed in patients with bulbous ichthyosiform erythroderma, lamellar ichthyosis, and pityriasis rubra pillars, etc, and the much poor responses in ichthyosis hystrix. The most frequent adverse reaction was mild to moderate dry lips (65.2%),the next were pruritus(39.1%),skin fragility(34.8%),and dry mouth(30.4%).The less frequent adverse reactions were alopecia(13%),anorexia(8.7%),headache (4.3%) and hypoacusis (4.3%).No effects on the growth and development were found in those children during the follow up period. Conclusions The considerable overall improvement is achieved with the acitretin therapy for children and adolescents with inherited keratodermas, with only mild to moderate adverse reactions and no effects on the growth and development in the children.
