This study was aimed to detect and identify the promoter CpG island methylation of γ-globin gene in peripheral blood mononuclear cells from patients with β-thalassemia major and healthy adult in Guangxi province, as well as to analyze the difference of promoter methylation rate of each CpG sites between them, and then to screen the promoter CpG island main methylation sites which maybe influence γ-globin expression. The template DNA was modified by bisulfite genomic sequencing PCR; the promoter sequences of γ-globin gene were amplified by technique Touchdown PCR, and then the PCR products were cloned and sequenced for obtaining methylation status of each CpG sites in target fragments, and then the accurate methylation sites and levels were detected quantitatively. The results indicated that the 4 CpG methylation sites locating at 28, 122, 231 and 234 bp in sequences were hypermethylated. As compared with healthy adults, the DNA methylation rate of 122 and 231 bp CpG sites in patients with β-thalassemia major was obviously lower, however, methylation rates of 28 and 234 bp sites were not significantly different between patients and healthy adults. It is concluded that the methylation sites 28, 122, 231 and 234 bp of γ-globin gene promoter are found both in patients with β-thalassemia major and healthy adults. The 122 and 231 bp sites are identified preliminarily to be involved in the regulation of γ-globin expression. This study provides the experimental evidence for alleviating the clinical symptoms of β-thalassemia major and targeting gene treatment through the regulation of γ-globin.

Objective To determine the clinical value of pulsed dual-wavelength 595 and 1064 nm laser in treating superficial infantile hemangioma. Methods The treatments were conducted in 260 patients with 270 lesions. The location of the lesions were 41 cases in scalp, 88 in face and neck, 79 in trunk and 62 in arms and legs. All lesions were treated several times with 595 nm (Group 1) and/or 1064 nm (Group 4) multiplex mode until the treatment was finished. The frequency of treatment was one to six times. The interval of the treatment was four weeks. Results The total effective rate was 95.56 %, with atrophic scar (8.15 %) but without severe ulcer. No significance was found as compared Group 1 parameter with Group 4 in formation of atrophic scars (x2 = 1. 870, P>0.05). Significant difference in the incidence of atrophic scars was found among different location of lesions (x2 = 15. 743, P<0. 01) : lesion in face had the highest probability. No obvious difference was found between different location of lesion and the frequence of treatment (x2 = 21.164, P>0.05), and so did with the efficacy (x2 = 11. 597, P>0.05). The size and the thickness of lesion had significant difference in the time of treatment (x2 = 58. 171, P<0. 01 and x2 = 11. 583, P<0.05, respectively).Conclusions 595nm/1064 nm dual-wavelength laser is a safe and effective tool for treating superficial infantile hemangioma. Choice of treatment parameter in the mode depends on the features of vascular lesions.

For patients with DTC,the side effect of 131I therapy on fertility and offspring is an important issue since genital tissues are highly sensitive to radiation.Exposure to 131 I radiation may result in transient impairment of gonadal function in male patients caused by elevated levels of serum follicle stimulating hormone and luteinizing hormone,low sperm count and motility.In female patients,exposure to 131I radiation may be complicated with delay of menstruation,oligomenorrhea and transient cessation of menstrual period.Most of these symptoms may resolve within one year after 131 I therapy.A slightly earlier menopause is the only reported long-term side effect of 131I therapy on ovarian function.Currently available data do not indicate that exposure to 131I may cause permanent infertility in male patients with DTC.For female patients with DTC,131 I therapy does not affect fertility or pregnancy outcomes beyond one year.
