The host protein SAMHD1 has been identified as the first mammalian deoxynucleoside triphosphate triphosphohydrolase (dNTPase), which blocks the infection of HIV-1 in non-cycling immune cells.SAMHD1 protein is highly expressed in human myeloid-lineage cells and resting CD4+T lymphocytes, which restricts HIV-1 replication by hydrolyzing the cellular dNTPs, thus inhibiting reverse transcription and viral complementary DNA ( cDNA) synthesis. Recent studies have revealed that SAMHD 1 plays an important role in virus whole life by promoting HIV -1 genome recombination, degenerating viral genome RNA and restricting virus transmission between cells .In this review, these progress on SAMHD1 research are summarized and the mechanisms by which SAMHD 1 mediates retroviral restriction are analyzed .

Objective: To observe the changes of Bcl-xl expression in hippocampus of the rats with the forced-swimming and the changes of Bcl-xl after poststress. Methods: The protocol was established with the forced-swimming as the chronic stress model. Open-field test was executed to measure the behaviors of the rats. Immunohistochemistry was used to observe the changes of Bcl-xl expression in the hippocampus. Results: Compared to the control group,the expression of Bcl-xl in CA3 region of the hippocampus and dendate gyrus(DG)of the rats was decreased morphologically. With the computerized image analysis, the gray degree increased significantly (P

AlM:To discuss the feasibility of microcoria optometry in screening for children ametropia. METHODS: Totally 217 school - age children were selected, included 94 first-grade students ( 6 ~ 8 years old) and 123 fourth-grade students ( 9 ~12 years old ) . Refractive diopter was measured with automatic refractor RM-8000 to evaluate the accuracy of micocoria optometry in screening ametropia.RESULTS: After cycloplegia, both the mean sphere diopter and cylinder diopter in grade one students changed significantly (P<0. 05), the mean sphere diopter in grade four students changed significantly (P<0. 05), while the mean cylinder diopter had no statistical difference ( P>0. 05 ) in grade four students. Different refractive type: before and after mydriasis spherical myopia, spherical equivalent difference was 0. 263 ± 0. 618 and 0.216±0.653D, with statistical significance (P<0.01);ln hyperopia group, spherical myopia, spherical equivalent difference was 0. 947±0. 946 and 1. 039±0. 984D, with statistical significance ( P = 0. 000 ). The lenticular difference between the two groups were not statistically different ( P > 0. 05 ). Choosing small pupil computer optometry for ≤- 1. 00D, ≥- 0. 50D child myopia or hyperopia could get more accurate value of diagnostic cutoffs, Youden index was 0. 672 and 0. 580. CONCLUSlON: Microcoria optometry can be as a effective method of screening of children with ametropia, but if for optometry, school-age children must accept mydriasis.

0.05).The 83 samples of HBV genotype B all belonged to subtype Ba,and we had not found subtype Bj.CONCLUSIONS The HBV genotypes among the children carriers of hepatitis B virus in Wenzhou mainly are the genotypes C and B.In two subtypes of genotype B mainly is the subtype Ba.

The trophoblast is fetal-derived and in direct contact with maternal tissues. The expression of the various types of MHC antigen in trophoblast cells is very important for successful pregnancy. Among nonclassical MHC class Ⅰ antigens, HLA-G is expressed specifically on cytotrophoblast cells and its expression protects the fetal from maternal immune attack. The expression of the distinct subtypes of classical MHC class Ⅰ antigen is different in different subtypes of trophoblast cells. The expression of MHC class Ⅱ antigen is inhibited in trophoblast during pregnancy. It is suggested that C Ⅱ TA plays an important role in regulation of MHC class Ⅱ gene expression.

Objective To explore the protective effect of Tea polyphenols(TP) on radiation injury in submandibular glands. Methods Sixty rats were randomly divided into radiation group(R-group) and tea polyphenols combined radiation group (TPR-group), both groups were irradiated with a single exposure of 15 Gy γ-rays delivered to the head and neck area. The rats were intragastrically administered with normal sodium or TP from 14 days before radiation to the experiment ended. On day 3, day 6 and day 30 after radiation, ten submandibular glands glands were taken from each groups. TUNEL method was used to examine the apoptosis of submandibular glands cells and immunohistochemical technique was used to detect the Bcl-2 and the Bax expression in the glands. The morphologic changes of submandibular glands were observed by transmission electron microscopy. Results Apoptosis index in the cell of submandibular glands were significant decreased on days 3, days 6 and days 30 after irradiation, compared with R-group ( F = 56.383, P ＜ 0.01 ). Expression of Bcl-2 and Bax were not significant difference between the two groups. The lesions of submandibular glands in TPR-group were lighter and the apoptosis in cell nuclear were not typical than that of R-group from electron microscope study. Conclusion TP could protect the sumandibular glands against radiation injuries and the mechanism might be realized with the anti-apoptosis in the glands cell.

OBJECTIVE: To analyze the possible effects of meteorological and environmental factors on the subjective symptoms of allergic rhinitis (AR) in children. METHOD: According to the daily subjective symptom records in AR children, the relationship between the subjective symptoms of AR in children and the meteorological environmental factors was analyzed. Mixed model was used to analyze the data. RESULT: The temperature and humidity had a negative correlation with symptoms score. Every 1 degrees C of temperature decrease was linked to 0.04 points increase in subjective symptoms scores (P < 0.01). Every 10% e in humidity decrease was linked to 0.04 points increase in subjective symptoms scores (P < 0.05). There was positive relationship between PM2.5, PM10 and symptom scores. Every 10 μg/m3 increase of PM2.5 or PM10 was linked to 0.02 (P = 0.0246) or 0.03 (P = 0.0293) points increase in subjective symptoms scores, indicating that air pollution could aggravate the symptoms of children in AR. CONCLUSION It suggested that higher temperature and higher humidity may induce lower sympotem while PM2. 5 and PM10 may induce higher sympotem in AR children.

OBJECTIVE: To investigate the impact of environment and message information for the treatment efficacy of children with allergic rhinitis (AR). METHOD: To choose 100 cases of children diagnosed with AR. The parents of children record daily symptom scores of AR of children everyday. While the doctors send the short message to the parents by using meteorological environment warning forecast technology to tell the parents the risk of AR attacks. We observe the morbidity of AR of the children and the treatment efficacy of children for 1 year. The 100 cases control group children diagnosed AR, their parents do not record daily symptom scores of AR and the doctors do not give the short message. We also observe the morbidity of AR of the control group children and the treatment efficacy of the children for 1 year. RESULT: The 100 cases intervention group children with AR, there are 11 cases refused to participate the group. We included a total 89 cases, 74 cases of children did a full year of intervention, 15 cases of children gave up. The control group 100 cases, nine cases refused to participate, 91 cases were included. The average episodes in the intervention group was 4. 67 times, the control group was 8. 12 times,--there were significant differences between the groups statistically. The execution rate on the prescribed clinic date in the intervention group visits was 91. 5%, while in the control. group, was only 67%. The compliance of parents of children to complete course of medication in the intervention group was 95. 6%, while the control group was 74.1%. Both sets of data are statistically significant differences. The children with sinusitis in intervention group was 26.97%, significantly lower than the 64.04% in the control group. The incidence in the intervention group and the control group of secretory otitis media was 8.99% and 6.60%, there was no statistically significant differences. CONCLUSION It can significantly increase the degree of attention of parents of children with AR that the parents of children record daily symptom scores of AR of children everyday, while the doctors send the short message to the parents by using meteorological environment warning forecast technology to tell the parents the risk of AR attacks. It can also improve the execution rate on the prescribed clinic date and improve compliance of parents of children to complete course of medication. It can significantly reduce seizure frequency and severity of episodes of AR, thereby improving the quality of life of children with AR, reduce the economic burden on families and society.
