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.

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.

Objective To evaluate and analyse the effectiveness of surgical treatment for fibrous dysplasia in proximal femur with severe varus deformity.Methods A retrospective study was performed in 21 patients (24 femora)of fibrous dysplasia who were treated in our hospital between August 2000 and May 2009.All patients had severe femoral varus deformity.The four-step procedures were performed orderlv as valgus osteotomy,lesion curettage,impacting of massive bone allograft,and fixation by femoral intramedullary nail.There were 6 patients with monostotic disease,15 with polyostotic diseases,including 12 males and 9 females with a mean age of 22.7 years(range,14-39 years).The average neck-shaft angle and femoral varus angle was 75°(range 55°-105°)and 30°(range,18°-45°),respectively.The average length of thigh shortened 3.4 cm(range,2.0-4.5 cm)compared with the contralateral thigh.Results All of the 21 patients were followed up from 21 months to 7 years with an average period of 3 years and 4 months.There were 30 osteotomy sites in 24 femurs,28 osteotomy sites showed bone union after 3-6 months from surgery.Two distal location of the double-level osteotomy showed nonunion,which received bone grafting again and got bone union after 3 months finally.The femoral mechanical alignments of the 21 patients had been recriticd.The average neck-shaft angle was 118°(range,95°-135°)postoperatively,the femoral varus angle disappeared.The average extremity lengthening was 2.8 cm(range,1.8-3.6 cm)postoperatively.There were no infection,recurrent fracture and progression of deformity.The visual analogue scales(VAS)score of 17 patients decreased to zero postoperatively from 7-10 preoperatively,and that of the other 4 patients decreased to 3-4 postoperatively from 8-10 preoperatively.The result of Harris hip functional score was excellent in 12 cases,good in 6,and fair in 3.Conclusion The valgus osteotomy can rectify varus deformity effectively.The reconstract nail of the fumer can support the stability of femur.Impacting of massive bone allograft can improve the capacity of the femur.

Objective:To study the effects of the conditioned medium (CM) from human lung adenocarcinoma cell line A549 on the viability and apoptosis of human umbilical vein endothelial cells (HUVECs) and the role of PI3K-Akt signaling pathway in the process. Methods:HUVECs were cultured with CM of A549 cells. Cell viability was detected by XTT assay. The morphological changes of HUVECs were analyzed by Hoechst 33258 staining and fluorescence microscopy. The apoptosis was detected by flow cytometry. Expression levels of total Akt and phosphorylated Akt were assessed by Western blotting. PI3K inhibitors wortmannin(WT)and Akt1 siRNA(siAkt1)were used to block PI3K-Akt signaling pathway. The mRNA transcription of Akt subtype was determined by RT-PCR.Results:A549 CM significantly increased cell viability after 24 h treatment (P=0.037) and inhibited apoptosis (P=0.001) of HUVECs. CM time-dependently activated phosphorylation of Akt. Akt was phosphorylated at 15 min after CM treatment and reached the peak at 30 min and then tended to decline. Both WT and siAkt1 blocked the effects of CM. Conclusion:The CM of A549 cells increased the survival and inhibit the apoptosis of HUVECs. Akt1 played a significant role in the process.

According to the 2010 Chinese pharmacopeia, salt processed and charcoal processed Eucommiae Cortex were pre- pared. HPLC-DAD analysis of the content of the bark and leaf of Eucommiae Cortex showed that the bark of Eucommiae Cortex mainly contained lignans such as pinoresinol glucose and iridoid including genipin, geniposide, geniposidic acid, while the leaf of Eucommiae Cortex consisted of flavonoids such as quercetin and phenolic compound such as chlorogenic acid. The content of pinoresinol diglucoside in the bark of Eucommiae Cortex was about 18 times more than that in the leaf of Eucommiae Cortex. The content of pinoresinol diglucoside in salted and charcoal processed Eucommiae Cortex decreased approximately by 30% and 85%, respectively. The content of genipin, geniposide and geniposidic acid in the bark of Eucommiae Cortex was about 3 times, 23 times, 28 times more than that in the leaf of Eucommiae Cortex.

OBJECTIVETo study the clinical effects of Fuzheng Huayu Gantang comprehensive therapeutic program (FHGP) on post-hepatitis B liver cirrhosis associated with glyco-metabolic abnormality (LCGA).

METHODSThe patients with LCGA enrolled in the randomized controlled clinical trial were assigned to 2 groups, the treated group (68 cases) and the control group (74 cases), they were treated respectively by FHGP and conventional TCM and Western medicine therapeutic program for 3 months. Indexes including fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2 h PG), fasting insulin (FINS) were detected, homeostasis model assessment insulin resistance (HOMA-IR) was calculated, and the score of syndrome was recorded before and after treatment. Then the effects on syndrome and glyco-metabolic abnormality were evaluated through statistical analysis.

RESULTSLevel of 2 h PG after treatment was lowered in both groups (P < 0.01), but significant difference was found in the pre-treatment to post-treatment decrement of FPG and HOMA-IR between the two groups (P < 0.05). The syndrome improving rate and the total effective rate on glyco-metabolic abnormality in the treated group were significantly better than those in the control group respectively (85.3% vs 64.9% , P < 0.01; 80.9% vs 62.2%, P < 0.05).

CONCLUSIONFHGP has the capability to improve the syndrome and glyco-metabolic abnormality of patients with LCGA.
