Objective To investigate the role of high-mobility group box-1 (HMGB1) in the pathogenesis and the treatment of rheumatoid arthritis (RA) and the pathogenesis of TWP in treatment of RA.Methods A rat model of collagen induced arthritis (CIA) was developed and CIA rats were divided into the model group, the TWP group, the MTX group and the combination treatment group. And the tissues and blood were drawn from the rats 4 weeks later. HMGB1 expression in synovium, joint and the sera were tested by immunohistochemical stain and ELISA. Results HMGB l expression of the model in the synovium, joint and serum [(23.8±2.2) ng/ml] were remarkably higher than the control [(7.4±1.6) ng/ml] (P<0.01); HMGB1 expression of the treatment groups in synovium, joint and serum [ (13.3±3.1), (17.4±4.9), (11.7±1.5 ) ng/ml]is obviously lower than the model (P<0.01), and were higher than that of the controls(P<0.05). Conclusion HMGB1 participates in the hyperplasia of synovial membrane, cartilage and bone destruction of CIA. The molecular mechanism for the TWP and MTX in the trentment of synovitis and bone destruction of RA is correlated with the expression of HMGB1.

AIM : To investigate the effects of FFBHQH on the level of expression of caspase 3 protein of middle cerebral artery in ischemia / reperfusion model and to study its mechanisms in preventing and treating ischemic apoplexy. METHODS : The model of focal cerebral ischemia / reperfusion in rats was established with the suture occluded method. The effects of FFBHQH on the behavior obstacle of rats after MCAO/R 24, 48, and 72 h were observed, and the levels of expression of caspase 3 protein were observed by immunoassay method in rats treated with FFBHQH after the cerebral ischemia / reperfusion. RESULTS : Different degrees of behavior obstacle appeared in rats after MCAO/R 24,48,72 h, and FFBHQH reduced the behavior obstacle grade. After MCAO/R, the expression of caspase 3 protein increased obviously, but FFBHQH reduced the expression. CONCLUSION : FFBHQH can prevent and treat the ischemic apoplexy, and the mechanisms may relate to the calcium antagonism and the prevention of the apoptosis correlated gene such as caspase 3 after cerebral ischemia.

Newborn brain damage is the main cause of new-borns' death and disabilities.Current research difficulties lie in analyzing characteristics of cerebral injuries,making objective prognosis and early intervention,as well as analysis of therapeutic effects after recovery.Since subjects are not requested to complete complex tasks while doing resting state functional MRI (rs-fMRI) tests,rs-fMRI is reckoned to be suitable for neonatal brain function research.So far,most rs-fMRI reports regarding cerebral injury are for adults,with only a few have been done on neonates.Foreign research are mainly focused on new borns' brain development.If relevant rs-fMRI research can be done on newborn brain damage,it would be helpful to accurately evaluate structure and function of patients' brain tissue damage.Further research can provide more valuable information in clinics.

Objective To observe the effect of osteopontin (OPN) and integrin αtvβ3 in collageninduced arthritis (CIA) and the possible mechanism of Tripterygium wilfordii polyglycoside (TWP) in the treatment of rheumatoid arthritis (RA). Methods CIA rats model were developed and were randomly divided into the experimental group and the TWP group.And tissue samples were obtained 4 weeks later.Then the expressions of OPN and integrin αvβ3 in the synovium,synovium fluid and serum of each group were determined by immunohistochemical stain and ELISA.Variance analysis was used for data analysis.Results The concentrations of OPN of the normal controls,experimental group and the TWP group in the serum were (5.7±2.9), (7.8±6.2), (5.0±1.9) ng/ml respectively and there were significant differences between these 3 groups (F=6.74,P=0.016).The concentration of OPN (measured by mean grey value) in the synovium and cartilage of the three groups were 229±15,81±15,93±13 and 211±17,91±19,100±15 and there were significant differences between the three groups (F=52.48,P<0.01; F=18.98,P=0.01).The concentrations of protein αvβ3 (measured by mean grey value) in the synovium and cartilage were 235±16,91±16,131±14 and 198±10,99±15,113±14,respectively and there were significant differences between the three groups (F=23.03,P=0.002; F=12.04,P=0.008).The expressions of OPN and integrin αvβ3 in the synovium,synovium fluid and serum of the experimental group were markedly higher than that of the controls.The expressions of OPN and integrin αvβ3 in the synovium,synovium fluid and serum of the treatment group were obviously lower than the experimental group.Conclusion OPN and integrin αtvβ3 are involved in the hyperplasia of the synovium,cartilage and bone destruction in CIA rats.The underlying molecular mechanism that TWP is effective in treating synovitis and bone destruction of RA is possibly related to down-regulation of the expression of OPN protein and integrin αvβ3.

Huaier (Trametes robiniophila) has been widely used as an adjuvant drug for cancer treatment in China. The anti-cancer effect of Huaier extract has been confirmed in liver cancer, lung cancer, breast cancer, ovarian cancer, gastric cancer, and so on. The main mechanisms by which Huaier exerts an anti-neoplastic effect include inhibition of the growth and proliferation of cancer cells, induction of apoptosis of cancer cells, suppression of angiogenesis, inhibition of the invasion and migration of cancer cells, regulation of oncogenes and tumor suppressor genes expression, improving immunity, and reversal of drug resistance in cancer cells. In order to provide references for further study and clinical application on anti-tumor effect of Huaier, the latest research progress on anti-tumor effect of Huaier in recent years is summarized in this paper.

Objective To investigate the characteristics of cognitive development of newborn's cerebral hemispheres with event related potential (ERP). Methods Forty-five healthy full-term newborns and 11 infants of 29-60 days in the Department of Newborns, Changzhou Children's Hospital between December 2013 and October 2015 were randomly included in this study. They fulfilled all inclusion/exclusion criteria. An auditory oddball paradigm was used with frequently occurring standand tones at 1 000 Hz with 90% probability and infrequent deviant tones at 2 000 Hz with 10% probability. Waveforms were recorded at Fz, Cz, F3, F4, C3 and C4 scalp locations. And a comparative study of area and latency of N2 was done at F3, F4, C3 and C4 scalp locations in the two hemispheres. Results N2 wave of 1-28 days neonatal at C3, C4 scalp locations: area (ms·μV) was 5 193.68±2 137.45 vs 4 324.51±1 334.73, with statistically significant difference (t=2.288, P=0.025);latency (ms) was 764.27±216.60 vs 878.29±294.06, also with statistically significant difference (t=2.185, P=0.031). N2 wave of 1-28 days neonatal at F3,F4 scalp locations: area (ms·μV) was 5 739.44±2 271.03 vs 5 614.87±2 280.83, without statistically significant difference;latency (ms) was 876.20±316.02 vs 860.45±289.04, also without statistically significant difference. N2 wave of 29-60 days infants at F3, F4 scalp locations: area (ms·μV) was 7 681.35±1 723.49 vs 5 993.55±735.63, with statistically significant difference (t=2.848, P=0.011);latency (ms) was 571.60±1.2248 vs 733.40±232.73, without statistically significant difference though F3 was shorter than F4. Conclusions The newborn's auditory perception cognition in the left side of central lobe is superior to the right side. With the growth of the newborn, the left side of the frontal lobe is also superior to that of the right side. Dominant hemisphere has appeared in the neonatal period. Proper stimulation can promote the newborn's cognitive development.
