?ln recent years, the number of patients with diabetes increase rapidly. Diabetic retinopathy ( DR ) , one of the complications of diabetes, is also the important aspect of current and future prevention of blindness in our country. Now, more and more scholar have noticed the important role of immune inflammation in the pathogenesis of diabetic retinopathy. ln this article, we reviewed the role of interleukin-6 ( lL-6 ) in diabetic retinopathy.

Objective Research the correlation between expression of MMP-2 in colorectal cancer and patho- logical factors,or biological behaviors in colorectal cancer.Methods The expression of MMP-2 in 68 cases with col- orectal cancer were detected by immunohistochemical staining.Results The expression of MMP-2 in colorectal can- cer was not correlated with tumor region and histologic type,but related with depth of tumor invasion and metasta- sis.The frequency of positive cases in patients with colorectal cancer with of lymph,node metastasis was significantly higher than that in patients without lymph node metastasis(P

Sphingosine kinase 1 (SphK1) plays critical roles in cell biological functions. Here we investigated the effects of SphK1 inhibitor SKI II on hepatoma HepG2 cell cycle progression and invasion. Cell survival was determined by SRB assay, cell cycle progression was assayed by flow cytometry, the ability of cell invasion was measured by Matrigel-Transwell assay and protein expression was detected by Western blotting. The results showed that SKI II markedly inhibited HepG2 cell survival in a dose-dependent manner, induced G1 phase arrest in HepG2 cell and inhibited cell invasion. SKI II markedly decreased the expressions of G1-phase-related proteins CDK2, CDK4 and Cdc2 and the levels of cell invasion-associated proteins MMP2 and MMP9. The results showed that SKI II inhibited cell cycle progression and cell invasion, implying SphK1 as a potential target for hepatoma treatment.

To evaluate the regulating effect of Buyang Huanwu decoction and its simple prescription (Naojian tablet) on CDK4/Cyclin D1 expression in hippocampus tissues of rats with cerebral ischemia, SD rats were divided into the sham-operation group, the model group, the Buyang Huanwu decoction group (ig, 3.15 g · kg⁻¹) and the simple prescription group (ig, 2.41 g · kg⁻¹). Each group was further divided into five subgroups based on time points after the administration, i. e. 1 d, 3 d, 7 d, 14 d and 28 d, respectively. CDK4/Cyclin D1 expressions of the group at different time points were examined by using immunohistochemistry and real-time qPCR. According to the results, the cerebral ischemia model group showed higher CDK4/Cyclin D1 expression than the sham-operation groups (P < 0.05), suggesting that the cell cycle signal pathway would be activated by the cerebral ischemic injury. Both Buyang Huanwu decoction and simple prescription groups showed significantly lower cyclin expression than the model group at 3 d, 7 d, 14 d, 28 d (P < 0.05), indicating both Buyang Huanwu decoction and its simple prescription could play the neuroprotective effect through the cell cycle signal pathway.

Objective To explore the pulmonary function,DVH and radiation pneumonitis after three-dimensional conformal radiation treatment ofⅢphase non-small-cell lung cancer.Methods 71 pa- tients (male 52,female 19,median age 63,KPS≥80) were evaluated by pulmonary function tests before radiotherapy and in M1 and M3 after radiotherapy respectively.After 3 months of follow-up time,it reviewed the appearance and grade of radiation pneumonitis.Then V_(20),V_(30) and MLD were worked out from dose vol- ume histogram.Results All patients completed radiotherapy,and total dose was 66-70 Gy.FVC (L), FEV1 (L) and CLCO were (2.58?0.65) L,(1.85?0.58) L and (15.15?4.65)ml/(min)before radio- therapy,with (2.96?0.76) L,(2.13?0.65) L and (14.71?3.92) ml/(min) in Ml after radiotherapy, with (2.65?0.61) L,(1.92?0.52) L and (13.15?3.71)ml/(min)in M3 after radiotherapy.The ac- cidence of radiation pneumonitis was 30%,moderate and severe radiation pneumonitis was 7%.With V_(20), V_(30) and MLD increasing,the grade of radiation pneumonitis was increasing.V_(20),V_(30) and MLD were related to the change in CLCO value among before,M1 and M3 after radiotherapy,and the correlation coefficient was more than 0.2.Conclusions There is a relationship in the pulmonary function,DVH and radiation pneu- monitis surely.The change in C_LCO value between before radiotherapy and M1 after radiotherapy could pre- dict the radiation pneumonitis.V_(20),V_(30) and MLD are not only correlated to radiation pneumonitis evidently but the change in FEV_1 and C_LCO after radiotherapy.
