Objective Radiation can cause multiple damages to tissues and organs.This study aimed to explore the protec-tive effect of Ganoderma lucidum polysaccharides ( GLPs) against the 60 Co-γray radiation injury in mice and provide an experimental basis for the clinical use of GLPs. Methods One hundred mice were randomly divided into five groups of equal number: normal control, gavage control, radiation control, high-dose GLPs, and low-dose GLPs.Models of radiation injury were made in the mice by whole-body exposure to 60 Co-γrays.Three days before and after mod-eling, the animals in the high-dose and low-dose GLPs groups were given GLPs intragastrically at the dose of 100 and 50 mg/kg respec-tively, once daily for 14 days.Then the 30 day survival rate and sur-vival time of the model mice were recorded and the changes in the pe-ripheral blood index, spleen index, and serum superoxide dismutase( SOD) activity were observed. Results GLPs significantly increased the 30-day survival rate and the mean survival time of the mouse models (P<0.05), decreased the reduction of WBC count in the peripheral blood, and shortened the time of WBC restoration ( P<0.05 ) .Furthermore, GLPs obviously improved the spleen index and SOD activity of the Co-γray irradiated animals. Conclusion GLPs, with a significant anti-radiation effect, can effectively raise the survival rate of the mice exposed to a lethal dose of 60 Co-γrays, reduce radiation injury to WBC and platelets, and increase the activity of SOD in irradiated mice.

To observe the expression of N - cadherin and fibronectin in retinal pigment epithelium ( RPE) cells in vitro under high glucose conditions, furthermore, to explore the effects of high glucose on epithelial -mesenchymal transition (EMT) in RPE cells.
●METHODS: Human RPE (hRPE) cells were cultured in vitro. Containing a final concentration of 60mmol/ L glucose was used for high glucose treatment. The cells were divided into normal glucose group (5. 5mmol/ L, NG) and high glucose group (24, 48 and 72h) respectively. The expression of N - cadherin and fibronectin in hRPE cells were evaluated by immunofluorescence and real -time PCR.
●RESULTS:RPE cells became disorganized and swollen over time under high glucose conditions, especially in 72h subgroup. lmmunohistochemical analysis revealed that the expression of N - cadherin in RPE cells under high glucose conditions was decreased compared with that in the control group, while the expression of fibronectin was increased. Real - time PCR results showed that the expression of N - cadherin mRNA in high glucose group was decreased at 24h compared with that in the control group, and declined markedly at 72h ( F = 12. 252, P =0. 000). There were no significant differences between the control group and the high glucose group at 24h, while the differences between the control group and the high glucose group (48 and 72h) were significant respectively (P < 0. 05 ). Meanwhile, the expression of fibronectin mRNA in RPE cells was increased in high glucose group at 24h, and reached the peak at 72h (F = 50. 543, P = 0. 000). There were no significant differences between the control group and the high glucose group at 24h. Compared with the control group, the expression of fibronectin mRNA in hRPE cells was increased significantly in high glucose group (48 and 72h) respectively (P= 0. 000, P= 0. 000).
●CONCLUSlON: The expression of epithelium marker N-cadherin is down - regulated under high glucose conditions in hRPE cells in vitro. Meanwhile, the expression of mesenchymal maker fibronectin is induced and appeared to EMT changes. Results of this study will enrich our growing understanding in proliferative diabetic retinopathy and hopefully lead to novel insights for the pathogenesis and therapeutic treatments.

Acute lymphoblastic leukemia (ALL) is a highly heterogeneous disease. The prognosis of adolescents and adults with ALL is worse than that of children with ALL, mainly because of differences in biological characteristics. Molecular markers are of great value on risk stratification, prognosis evaluation, treatment guidance. The good news is with the deepening of studies on pathogenesis of ALL and the introduction of new technologies, novel molecular markers of prognostic relevance continue to be discovered. It was found that increased Sox4 expression was shown to correlate with accelerate leukemia progression. Unfortunately, resistance to medicine is associated with two cyclin-dependent kinase-inhibitor-2AB (CDKN2A/B) deletion.And the deletion of IKZF1 increase risk of relapse. Meanwhile, Ph-like acute lymphoblastic leukemia is characterized by a variety of genetic alterations that activate kinase or cytokine receptor signaling pathway. Identification of these molecular markers will provide important insights into the treatment strategies. This paper reviewed the advance in the Ph-positive ALL and Ph-like ALL.

The quality markers (Q-markers) of traditional Chinese medicine (TCM) have become a topic of interest in TCM research in recent years. Nonetheless, there is still no consensus on how to scientifically characterize TCM Q-markers. Our study establishes an identification method for TCM Q-markers based on the analytical hierarchy process (AHP) and the entropy weight comprehensive method. By constructing an evaluation system encompassing the target layer, the factor layer and the control layer, AHP can be used to analyze the weight of three core TCM quality attributes, including effectiveness, testability and specificity. Following that, the entropy weight method is employed to analyze the specific indicators for each attribute based on the literature and experimental data. Finally, the comprehensive weight of each index is obtained by combining the two weights, and the comprehensive weight and the specific value of each component is multiplied and summed to obtain the integrated score ranking, and thereby identify the TCM Q-markers. Taking Shaoyao Gancao decoction as an example, the analysis revealed that the top 8 components are as follows: paeoniflorin > quercetin > albiflorin > glycyrrhizic acid > naringenin > liquiritin > oxypaeoniflorin > benzoylpaeoniflorin, and can be identified as Q-markers of Shaoyao Gancao decoction. This study not only provides support for the establishment of quality standards and process quality control of TCM formulae, but also provides innovative ideas and methods for quantitative evaluation and accurate identification of TCM Q-markers.

Objective To detect the expressions of CD19 and CD20 of B-lymphocytes (CD19+B, CD20+B) and natural killer (NK) cells in the peripheral blood of epileptic children and explore their significances. Methods Four hundred and fifty-eight epileptic children, admitted to our hospital from January 2008 to December 2010, were chosen as patient group; another 52 healthy subjects were chosen as controls. The expressions of CD19+B and CD20+B and NK cells were detected by flow cytometry; their results were compared. Ninety-two epileptic children were treated with intravenous immunoglobulin (IVIG) and the effect of IVIG therapy was studied. Results The CD19+B level ([22.35±6.54]％) and CD20+B level ([21.50±8.41]％) in the epileptic children were obviously higher than those in the healthy controls ([16.86±4.02)％,[16.13±4.19]％, P＜0.05); and the level of NK cells ([9.1 1±4.90]％) in the epileptic children was significantly decreased as compared with that in the healthy controls ([14.72±4.15]％, P＜0.05). The CD19+B level ([18.26±5.03]％) and CD20+B level ([16.74±5.12]％) 6months after MG treatment were decreased significantly as compared with those before treatment ([22.74±6.25]％,[21.61±8.03]％, P＜0.05]; while the level of NK cells ([14.65±4.58]％) 6 months after IVIG treatment was increased significantly as compared with that before treatment ([9.07±4.76]％,P＜0.05). Among the 92 patients treated with IVIG, 70 enjoyed good results and 22 had non-effective resutls; The changesofCD19+Blevel ([7.99±5.34]％) and CD20+B ([8.21±5.21]％) before and after treatment in effectively treated patients by IVIG were significantly different as compared with those in ineffectively treated patients by MG ([3.78±2.76]％,[3.66±2.48]％, P＜0.05); however, the changes of level of NK cells before and after treatment showed no significant difference between effectively treated patients and ineffectively treated patients ([5.28±4.55]％,[4.53％±4.43]％, P＞0.05). Conclusion Dysfunctions of B-lymphocytes and NK cells exist in epileptic children, and MG treatment shows good effect on immune dysfunction of them. The levels of CD19-B and CD20-B can be used as monitoring indicators in the IVIG treatment of epileptic children.
