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.

Objective To explore the expression and activation of nuclear transcription factor ?B(NF ?B) in human breast cancer (BC), and the relationship between the activity of NF ?B and malignant potential of BC.

Objective To study the features of anatomical delamination of the posterior renal fascia in CT images.Methods Clinical datas and CT images of 85 patients with acute pancreatitis were collected,the anatomical delamination features of the adult posterior renal fascia were observed and recorded.Results (1) 23 cases showed anatomical delamination of the left posterior renal fascia, 9 cases showed anatomical delamination of the right posterior renal fascia, and 8 cases showed anatomical delamination of bilateral posterior renal fascia.(2) The features of anatomical delamination of the posterior renal fascia were detected in the whole posterior renal fascia or in the lateral part of the posterior renal fascia.Anatomical delamination was detected in the whole left posterior renal fascia in 6 cases, and was detected in the lateral part of the left posterior renal fascia in 17 cases.Anatomical delamination was detected in the whole right posterior renal fascia in 4 cases and in the lateral part of the right posterior renal fascia in 5 cases.Anatomical delamination of the whole part in the bilateral posterior renal fascia were detected in 4 cases and pure delamination of the lateral part in the both sides were 4 cases.Conclusion CT images can show the anatomical delamination of the posterior renal fascia which has two types.The anatomical delamination of bilateral posterior renal fascia is not always the same.

In order to explore the effects of Panax notoginoside (PNS) on the expression of transforming growth factor β1 (TGF-β1) and Smad-7 in renal tissues of diabetes, a rat model of diabetic nephropathy was set up by intravenous injection of streptozotocin (STZ). Wistar rats were randomly divided into normal group, diabetic control group, group treated by PNS at low-dosage (PL), group treated by PNS at high-dosage (PH) and group treated by catopril (C), respectively. Fasting blood glucose (FBG), renal index, endogenous creatinine clearance rate (C(Cr)) and urinary albumin (UAlb) in 24 h were examined after 6 weeks. Meanwhile, the expressions of TGF-β1 and Smad7 in renal tissues were immunohistochemically dectected. At the end of the sixth week, FBG, renal index, C(cr), UAlb were all elevated significantly in control group (P<0.01). The expression of TGF-β1 protein was increased while Smad7 protein decreased in renal tissue (P<0.01). However, the treatment with PNS reversed the aforementioned changes in renal tissues of diabetic rats. These results indicate that PNS possess a protective effect on the kidney of diabetic rats and it might protect kidney by inhibiting the expression of TGF-β1 protein and enhancing the expression of Smad7 protein.

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.

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.
