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 study the changes of Neuroendocrine immunology sensitive indicators in children with Hand-Foot-and-Mouth Disease (HFMD) and values of determining the patient′s conditions. Methods The children with HFMD were divided into three groups , the common group , severe group and risk group according to the clinical diagnosis and classification standards, meanwhile, the healthy children were enrolled as control group. Peripheral blood samples were collected from the case groups and control group , concentrations of cortisol (COR), β-endorphin (β-EP), interleukin-13 (IL-13), interferon-γ (IFN-γ), immunoglobulin (IgG, IgA, and IgM), and the relative contents of T cell subsets, B cells and NK cells were tested respectively. Results Compared with the control group, the levels of COR, β-EP, IL-13, IFN-γ and IgG, IgA, IgM all significantly increased in the three groups of HFMD. All the differences were statistically significant (P < 0.01), except the difference of IgG, and IgA between the ordinary type and the control group. Compared with the common group, the percentage of NK and B cells dramatically increased, meanwhile, compared the other two types with the control group , the percentage of T cell subsets and NK cells significantly decreased , but B cells significantly increased, and there were all significant difference (P < 0.01). Conclusions HFMD caused by EV71 infection is the result of the combined effect of changes in nervous system , immune system and endocrine system. It is extremely important to detect early the sensitive indicators in children with HFMD , such may help to find the risk cases and carry on early intervention for patients′ recovery.

Objective To determine the activities of 131I for treating differentiated thyroid carcinoma with diffuse pulmonary metastases ( DTC-DPM ) from the perspective of internal radiation dosimetry.Methods According to Medical Internal Radiation Dosimetry (MIRD) schema, the activity constraint,from which the whole bdy retention at 48 h should not exceed 2.96 GBq (2.96 GBq rule), was converted to dose-rate constraint(DRC) to lungs at 48 h ( DRCLU ·48 h ) in 131I therapy for DTC-DPM. Based on the assumption of DRCLU·48 h at 48 h in lung, the fractions of whole body activities ( F48 ), the effective half times of 131I in lungs ( TLL ) and the remainder of body ( TRB ) were 0.6-0.9, 20- 120 h, and 10- 20 h, respectively. The maximum safe activities of 131I for different human phantoms from the Organ Level Internal Dose Assessment (OLINDA) software were calculated. Results According to MIRD schema and 2.96 GBq rule, DRCLU ·48 h should not exceed 46.4 mGy/h in 131I therapy for DTC-DPM. Depending on varying F48 h,TLL and TRB, the maximum safe activities of 131I were 6.77-81.36, 5.29-56.20, 5.08-55.19 and 3.87-40. 52 GBq for the male adult, female adult, 15-year-old, and 10-year-old patients with DTC-DPM, respec tively. Conclusion Dosimetry-guided 131I therapy for DTC-DPM considers adequately the differences of 131I kinetics in individual patients and can adjust administered activities of 131I on the precondition of avoiding radiological pneumonitis and pulmonary fibrosis.

Objective To study the effects of robot-assisted therapy combined with electromyographic biofeedback (EMGBF) on upper limb function after stroke.Methods Thirty acute stroke patients were randomly divided into two groups of 15.The patients in the control group received a conventional rehabilitation program and EMGBF.The patients in the treatment group received robot-assisted therapy for 30 minutes daily,6 days a week for 3 weeks combined with EMGBF on the basis of the conventional rehabilitation program.Upper limb motor function and ability in the activities of daily living (ADL) were assessed with the Fugl-Meyer upper extremity assessment (FMA) and a functional independence measure (FIM) before treatment,at 3 weeks and 3 months after treatment.Results After treatment the FMA and FIM scores of both groups were significantly better than before treatment.At 3 weeks after treatment there was no significant difference in the average FMA scores of the two groups,but at 3 months after treatment the patients in the treatment group had significantly better scores.No significant differences in FIM scores were observed at 3 weeks or 3 months.Conclusions Robot-assisted therapy combined with EMGBF can improve upper limb motor function significantly in acute stroke patients,and more effectively than EMGBF.But no significant advantage in improvement in ADL performance was observed with Robot-assisted therapy combined with EMGBF over EMGBF.

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.
