Objective To investigate the standardized treatment of 33 children with thalassemia and their family financial burden registered in Bao'an district, Shenzhen city, and to provide basic information for formulating health policy for the government. Methods In 2009, preliminary investigations on 39 registered families with thalassemia children were conducted by telephone, and a household survey was made to collect treatment and economic status by questionnaire on 33 children. Results Among 33 cases of thalassemia children, 21 cases(63.7%) were severe anemia, 5 cases( 15.1%) in need of care or special care, and 25 cases(75.8%) were difficult or unable to maintain standardized treatment. The average family monthly income and expenditure was (4060 ± 2002) and (4926 ± 2991) yuan, respectively. The average monthly treatment costs were (2665 ± 1872) yuan, and the average debt amounted to (64 600 ± 53 940) yuan. Fifteen families[60.0%(15/25)] would reduce the times of blood transfusions or iron transpirations when they encountered revenue deficiency. Conclusions The heavy economic burdens on families with children thalassemia result in inadequate or interrupted treatment on sick children and affect their survival and quality of life, which should be taken more attention and social care.

Background To optimize the culture method of human retinal microvascular endothelial cells is very important for the study of retinal angiogenesis disease.Human retinal microvascular endothelial cells have been successfully cultured in previous studies,but further improvement of the culture method to harvest higher yields and purity cells is still needed.Objective This study was to design a modified method to isolate and purify human retinal microvascular endothelial cells much easily and quickly,and to compare the expression of specific markers of vascular endothelial cells,factor Ⅷ and CD31/CD34 in the cells.Methods The use of human donor eyeballs was approved by the Ethic Commission of Zhongshan Ophthalmic Center of Sun Yat-sen University.The retina tissue from healthy donor was isolated and digested by the two-step digestion method with 2％ trypsin and 0.133％ collagenase Ⅳ.Human retinal microvascular endothelial cells were collected and plated in 60 mm dishes coated by 0.1％ fibronectin and cultured in endothelial cell-specialized medium supplemented with 10％ fetal bovine serum,0.3 mg/L β-endothelial cell growth factor (ECGF) and 100 ng/L sodium heparin.During the culturing,the growth situation of the cells was monitored by morphological observation,and immunohistochemical staining was performed to probe vascular endothelial cell-specific membrane protein CD31,CD34 and factor Ⅷ for identification of the cell purity.Results Human retinal microvascular endothelial cells were isolated successfully from the retina by the twostep digestion method.The primary cultured cells adhered to well 72 hours later and achieved confluence with the typical cobblestone appearance 9 to 10 days after cultured.The cells exhibited the blue nuclei and reddish cytoplasm by regular haematoxylin and eosin stain and showed a strong positive response for CD31,CD34 and factor Ⅷ by immunohistochemistry.The positive dye of CD31 and CD34 was lower than Ⅷ factor in both endothelial cells.Conclusions Modified culture method of human retinal microvascular endothelial cells can improve cell culture result and purify target cells.

Objective To measure the levels of human interleukin (IL)-32 in the serum and induced sputum of patients with chronic obstructive pulmonary disease (COPD) and investigate the possible roles of IL-32 in COPD.Methods Sixty patients with acute exacerbation of COPD ( AECOPD),60 patients with stable COPD,and 30 healthy subjects were recruited.The concentrations of IL-8,tumor necrosis factor alpha (TNF-α),and IL-32 in serum and induced sputum were measured by enzyme-linked immunosorbent assay (ELISA).The correlations among IL-32,IL-8,TNF-α,and lung functions were investigated. The data were analyzed using a statistical software package (SPSS 13.0).Variables were compared with one-way ANOVA,and correlations among variables were analyzed using Pearson's correlation coefficient or Spearman's correlation coefficient.Results The serum IL-32 level was significantly higher in AECOPD patients [(175 ± 88) ng/L] than in healthy subjects [ (59 ± 21 ) ng/L] and in stable COPD patients [ (89 ± 34) ng/L] (P ＜ 0.05) ; the serum IL-32 level was also significantly higher in stable COPD patients than in healthy subjects (P ＜ 0.05).The sputum IL-32 level was significantly higher in AECOPD patients [ ( 163 ± 117) ng/L] than in healthy subjects [ ( 75 ± 38 ) ng/L] and stable COPD patients [ ( 108 ± 63 )ng/L] (P ＜0.05); the sputum IL-32 level was also significantly higher in stable COPD patients than in healthy subjects ( P ＜ 0.05 ).The sputum IL-32 level in AECOPD patients was positively correlated with the sputum IL-8 and TNF-α levels (r =0.49 and 0.53,respectively) (P ＜0.01 ).The sputum IL-32 level in AECOPD patients was negatively correlated with FEV1 predicted values,FEV1/FVC,and PaO2 (r =-0.44to -0.33) (P ＜ 0.01 ).The serum IL-32 level in AECOPD patients was positively correlated with the serum IL-8 and TNF-o levels (r =0.45 and 0.61,respectively) (P ＜ 0.01 ).The serum IL-32 level in AECOPD patients was negatively correlated with FEV1 predicted values,FEV1/FVC,and PaO2 (r =-0.46to - 0.29) ( P ＜ 0.01 ).Conclusions IL-32 may be involved in the pathogenesis of airway inflammation in COPD.IL-32 may be a useful marker of acute exacerbation of COPD.
