Objective To study the effect of ahylysantinfarctase (AF) on the growth of fetus lens epithelial cells (LECs) in vitro. Methods Fetal lens anterior capsule membranes from the eyeballs of dead fetus delivered by induced labor underwent primary cell culture with the modified method. The second or third generations of fetal LECs were used in this experiment. They were exposed to AF of six kinds of concentrations (2?10~ -4 , 4?10~ -4 , 8?10~ -4 , 16?10~ -4 , 32?10~ -4 , 64?10~ -4 u/mL). Their morphologic changes were observed with the inverted microscope and the value of absorption (A) in each well was tested by MTT assay to examine the effect of AF on the growth of the fetal LECs collected. Results In the experimental groups, especially AF groups of higher concentration, LECs exhibited inordinate shape, less kytoplasm, more cellular endoparticles, wider intercellular space and random disposition, and even adherence failure. After the cells grew in AF of different concentrations for 48h, A value in each group decreased with the increase of AF concentration, and differed significantly between all the experimental groups (P

OBJECTIVETo provide evidence for Chinese medical treatment of children with EB virus infection by exploring its clinical efficacy from multiple angles.

METHODSTotally 81 children patients were randomly assigned to the treatment group (46 cases) and the control group (35 cases). Patients in the treatment group took Chinese medical decoction, while those in the control received intravenous dripping of Ganciclovir and oral administration of pidotimod. The treatment period for the two groups was 2 weeks. Patients were followed-up till the 12th week. Clinical symptoms such as fever, lymphadenopathy and hepatosplenomegaly, as well as lab indices such as abnormal lymphocyte percentage, EB virus antibody, virus DNA load, T cell subsets, immunoglobulin, and so on were observed before and after treatment, at week 4 and 12 of follow-ups.

RESULTS(1) The total effective rate at week 2 was 95.6% in the treatment group, higher than that of the control group (94.3%), but there was no statistical difference between the two groups. (2) The time for defervescence, duration of pharyngeal hyperemia, duration of swollen tonsils was shorter in the treatment group than in the control group (P<0.05). The subsidence of lymphadenopathy, hepatomegaly, and abnormal lymphocytes was better in the treatment group than in the control group (P < 0.05). (3) The positive cases of peripheral blood hetero-lymphocyte was significantly reduced after treatment, at week 4 and 12 of follow-ups both in the treatment group and the control group (P < 0.01). The expression of IgA and IgM decreased after treatment in the two groups when compared with before treatment in the same group (P < 0.05, P < 0.01). IgG in the treatment group also obviously decreased after treatment, at week 4 and 12 of follow-ups (P < 0.05, P < 0.01), while it decreased only after treatment in the control group (P < 0.05). Activities of AST and ALT in the treatment group and the AST activity in the control group were markedly improved when compared with those before treatment (P < 0.05). Compared with the control group, the abnormal lymphocyte positive case number obviously decreased in the treatment group after treatment, at week 4 and 12 of follow-ups (P < 0.05). (4) After treatment, at week 4 and 12 of follow-ups, CD3+ and CD8+ significantly decreased; CD4+, CD4/CD8, and B cells significantly increased in the two groups, when compared with before treatment (P < 0.05). NK cells significantly increased more in the treatment group after treatment, at week 4 and 12 of follow-ups, higher than before treatment as well as the control group (P < 0.05). (5) EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the two groups after treatment, at week 4 and 12 of follow-ups (P < 0.05). Compared with the control group, EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the treatment group after treatment and at week 4 of follow-ups (P < 0.05).

CONCLUSIONSTreatment of EB virus infection by Chinese medical treatment was effective. It could promote the recovery of EB viral infection, and reduce the risk of vicious disease after EB viral infection.

PCA showed that the Atracylodis Macrocephalae Rhizoma from Panan County, Yuqian Town, Jinyun County, Xinchang County of Zhejiang Province had the best quality, from Bozhou City and Fuyang City of Anhui Province had good quality.Conclusion The established multi-index quality evaluation method based on PCA model can be applied to objectively evaluate the quality of Atracylodis Macrocephalae Rhizoma from different producing areas.

Objective To detect the changes and clinical significance of the expression of anti‐GPⅡb/Ⅲa and anti‐GPⅠb/ⅠX on anti‐secreting B cells in patient with thrombocytopenia .Methods Expression of anti‐GPⅡb/Ⅲa and anti‐GPⅠb/ⅠX specific autoantibodies in thrombocytopenia were tested with (CBA) .Results There were significantly more circulating anti‐GPⅠ b/ⅠX and anti‐GPⅡb/Ⅲa antibody‐producing B cells in primary ITP(P<0 .05) for all comparisons .For diagnosing primary ITP ,the an‐ti‐GPⅠb/ⅠX had 43% sensitivity and 89% specificity ,whereas the anti‐GPⅡ b/Ⅲ a had 86% sensitivity and 83% specificity . When two tests were combined ,the sensitivity improved to 90% without a reduction in specificity .Conclusion The assay for detec‐ting anti‐GPⅠb/ⅠX is useful for identifying patients with ITP ,but its utility for diagnosing ITP is inferior to the anti‐GPⅡb/Ⅲa assay .

Objective To analyze the clinical and pathological characteristics of thyroid nodules.Methods A retrospective analysis of the clinical data of 2843 Han patients with thyroid nodules from January 2009 to June 2011 in Henan province was performed.Results The most high-risk of thyroid nodule resided in the group aged 45-54.The main pathological manifestation was simple nodular goiter.The rate of preoperative misdiagnosis was 2.4％.22.1％ of the patients with thyroid nodules showed abnormal thyroid function,which was mainly as subclinical thyroid dysfunction.The positive rate of thyroid peroxidase antibody (TPOAb) in patients with thyroid nodule was 19.8％ while that of thyroid globulin antibody (TgAb) was 20.0％.Among all 2843 subjects,the prevalence of differentiated thyroid carcinoma (DTC) was 28.8％,and the incidence of DTC was accompanied by raised TSH levels.The prevalence of DTC exceeded 40％ in patients aged between 25 to 34 as well as more than 74 years old.The prevalence of DTC was up to 33.8％ in TgAb positive patients.There was no difference in TPOAb levels between DTC patients and non DTC patients (P =0.406),but the TgAb level in patients with DTC was significantly higher than that of non DTC patients (P =0.033).Conclusion Thyroid nodule patients aged 25-34 or older than 74 formed high-risk groups of DTC.The serum TSH level and TgAb level were positively correlated with the risk of DTC.

?Advances in genome-wide analysis have revealed that up to 90%of the human genome is transcribed.However, only approximately 1% of RNA transcripts encode proteins, and the remaining transcripts are noncoding RNAs.Noncoding RNAs can be roughly divided into small noncoding RNAs (<200nt ) and long noncoding RNAs ( LncRNAs, >200nt ). Small noncoding RNAs include microRNAs, transfer RNAs and small nucleolar RNAs, whereas the long noncoding RNAs comprise ribosomal RNA, natural antisense transcripts, etc. Although the biosynthesis and biological activities of microRNAs are well studied through bioinformatics and active biological molecules analysis, the understanding of LncRNAs on these aspects is still limited.LncRNAs play multiple roles in regulating gene transcription and translation, and epigenetics.Aberrant LncRNAs expression can occur in various pathological processes and significantly related to the pathogenesis or poor prognosis of ophthalmological diseases. In this review, we will focus on the characteristics and regulatory functions of LncRNAs that are commonly associated with ophthalmological diseases.
