Objective To study the effect of curcumin on the expression of inflammatory factors in model rats with chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS) type Ⅲ.Methods The rats were randomly divided into following groups: sham-operated group(sham), CP/CPPS model group(model), curcumin 50 mg group(cur-50 mg) and curcumin 100 mg group(cur-100 mg) and p38 inhibitor group(SB203580).Drug was given to each treatment group for 12 days by intraperitoneal injection.The levels of TNF-α, p38, COX-2 mRNA was measured by Real-Time PCR.The expressions of TNF-α and COX-2 proteins were measured by immunohistochemistry.The levels of p38, p-p38 and NF-κB proteins were detected by Western blot.Results NF-κB, p-p38, TNF-α, COX-2 proteins and TNF-α, p38, COX-2 mRNA in model group were higher than those in the sham group (P<0.01);cur-100 mg group and SB203580 group could significantly relieve these change in the model group (P<0.01);COX-2 mRNA and protein in cur-100 mg group decreased more than that in SB203580 group;p-p38 was positively correlated with NF-κB in curcumin groups and SB203580 group compared with model group (P<0.01).Conclusions Curcumin can reduce the expression of inflammatory cytokines NF-κB, TNF-α, COX-2 and p-p38 in rats with CP/CPPS type Ⅲ.

Objective: To observe the synergetic effect of folic acid and genistein on apoptosis in the early stage of neuron and its possible mechanism. Methods: Cyclophosphamide was added to primary cultured neurons to induce apoptosis. Three different dosages of folic acid and genistein were used to inhibit apoptosis. The results were observed by flow cytometry and scanning electron microscopy (SEM). Results: 1.Folic acid and genistein might play a role in early stages of neuron apoptosis, and the synergetic effect was demonstrated when folic acid and genistein were administered together. 2. The membrane changes in early stages of neuron apoptosis observed by scanning electron microscope were also in agreement with the flow cytometry data. Conclusion: Genistein might reinforce the protective effect of folic acid on neural tube defects by restraining the apoptosis of the early stage of neuron.

Purpose To detect the expression of insulin-like growth factor-ⅡmRNA-binding protein 3 (IMP3) in preeclampsia (PE) placentas. Methods The levels of IMP3 expression were measured using immunohistochemistry in 8 cases of mild PE, 41 cases of se-vere PE, 6 cases of fetal growth restrict ( FGR) without PE and 22 cases of normal late trimester of pregnancy placentas. Results Compared with normal late trimester of pregnancy, the expression of IMP3 was obviously decreased in severe PE placenta ( Z =-2. 063,P<0. 05), decreased in mild PE (Z= -1. 31,P>0. 05). The expression of IMP3 in severe PE placenta was lower than that of mild PE placenta but not statistically significant (Z= -0. 233,P>0. 05). The expression of IMP3 in early onset PE placenta was lower than that of late onset PE placenta but not statistically significant(Z= -0. 108,P>0. 05). Compared with normal late tri-mester of pregnancy, the expression of IMP3 was significantly decreased in PE with FGR placenta (Z= -2. 375,P <0. 05), de-creased in FGR without PE and PE without FGR (Z= -1. 225,P>0. 05, Z= -1. 36,P>0. 05). Conclusion The results indicate that IMP3 protein expression is low in sever PE, which may be one of the pathogenesis of PE. IMP3 may be used as a marker to predict PE with FGR, and to provide a basis for the development of a novel therapeutic target in PE.

Objective To study the difference of image quality and radiation dose between different exposure modes with full-field digital mammography (FFDM).Methods The Fluke18-220mammographic phantom was exposed by FFDM system with different exposure modes at automatic exposure control ( AEC ) ,including contrast mode,standard mode and dose mode,and the exposure factors and radiation dose were recorded.The images on monitor with the best window width and window level were read by four independent radiologists.The images of specks groups,nylon fibers and masses was assessed by the four experienced readers at the criterion of American College of Radiology.Results The detection of specks groups,nylon fibers and masses were statistically different at the contrast mode and standard mode (F =41.321,P < 0.05),further at the contrast mode and dose mode.The detection of specks groups、nylon fibers and masses were not statistically different( P > 0.05 ) at standard mode and dose mode,but the radiation doses were different.The ESD at standard mode and dose mode was 4.5 and 3.15 mGy,respectively.The AGD of standard mode and dose mode was 1.18 mGy and 0.78 mGy,respectively.Conclusions The standard mode and dose mode of FFDM might be fit for most patients,especially at the dose mode.Contrast mode of FFDM should be strictly controled in use.

The nuclear factor erythroid 2 related factor 2 (Nrf2) is a key protein of endogenous antioxidant defense systems in the body. In response to oxidative stress, Nrf2 translocates to nucleus and binds to antioxidant response elements (ARE), regulating the expression of a large amounts of antioxidant genes and maintaining a proper redox balance. The pathological processes of neurodegenerative diseases are associated with generation of reactive oxygen species, which cause oxidative stress. Oxidative stress plays a cardinal role in the onset and progression of neurodegenerative diseases. Nrf2-inducer compounds can reduce oxidant stress and have shown therapeutic efficacy in many neurodegenerative disease models. How to activate the Nrf2 signaling pathway effectively has been received much attention. Here we provided an overview of specific mechanism of Nrf2-ARE pathway and the protective effects of Nrf2 in different neurodegenerative diseases, and summarized the Nrf2 activators recently in preclinical study.
