OBJECTIVETo discuss the role of early growth response factor (Egr)-1 and it's upstream signaling pathway in the development of silicosis.

METHODSThe expression and localization of Egr-1 were analyzed by immunofluorescence and in-situ hybridization. The activity of Egr-1 was observed in treated cells by using a reporter plasmid and EMSA, the activity of ERK1/2 in RAW264.7 incubated with SiO(2) by using a kinase assay, and further by using a kinase inhibitor assay to investigate the role of upstream kinase in the signal pathway of the activation of Egr-1.

RESULTSThe obvious increase of expression and transcription of Egr-1 was observed shortly after being treated by silica and its activity increased abruptly. There was an increase of the activity of ERK1/2 in RAW264.7 cells treated, which reached a peak at 30 minutes. The expression and transcription of Egr-1 decreased maniferstly after using kinase inhibitors.

CONCLUSIONEgr-1 expression can be induced by silica dioxide in RAW264.7 cells, and the ERK1/2, p38 kinases may take part in this process which suggest the pathway of SiO(2), ERK1/2, p38 and Egr-1 may play an important role in the development of silicosis.

OBJECTIVETo study the expression and location of early growth response gene-1 (Egr-1), transforming growth factor-beta(1) (TGF-beta(1)), fibronectin (FN) in silicotic rat and to discuss the role of Egr-1 in the development of silicosis.

METHODSSilicotic animal model of rat was established, and the expressions of Egr-1, TGF-beta(1), FN in various lung cells of silicotic rat were analysed by using immunohistochemical technique (SP) and the image analysis.

RESULTSThe expressions of Egr-1 in bronchial epithelial cell, pulmonary macrophage, alveolar epithelium cell and interstitial cell in lung silicotic tissue (gray values: 118.58 +/- 5.65 - 168.52 +/- 5.67) were higher than those of controls (gray values: 166.23 +/- 5.23 - 188.12 +/- 8.35) during 1 - 28 days, and the expression was mainly in nucleus; the expressions of TGF-beta(1) in these cells (gray values: 123.49 +/- 5.65 - 170.24 +/- 3.56) were also higher than those of controls (166.53 +/- 6.25 - 198.56 +/- 4.53), and the expression was mainly in cytoplasm. The expressions of FN in bronchial epithelial cell, pulmonary macrophage and alveolar epithelial cell (gray values: 150.32 +/- 6.54 - 201.54 +/- 7.38) were lower, while those in interstitial cell (gray values: 121.43 +/- 5.65 - 167.55 +/- 6.35) were higher than those of controls. The changes of TGF-beta(1) and Egr-1 expression level in bronchial epithelial cell, pulmonary macrophage, alveolar epithelium cell and interstitial cell were synchronous during the experiment (1 - 28 days). Both of them were correlated with each other (r = 0.61, P < 0.01), while the expression of FN was not correlated with Egr-1, but correlated to TGF-beta(1) in interstitial cell (r = 0.46, P < 0.01).

CONCLUSIONSilicon dioxide could up-regulate the expression of nuclear transcription factor Egr-1 in several kinds of cell in lung. The activated Egr-1 may coordinate the expression of TGF-beta(1) and FN to regulate the development of silicosis.

OBJECTIVETo analyze the radiological parameters of the conservatively in treating distal radius fracture and investigate whether the final re-displacement can be predicted after primary reduction.

METHODSFrom January 2013 to June 2014,212 patients with distal radial fracture conservatively were treated in our hospital, 107 patients of them were excluded because of their incomplete radiological parameters;the remaining 105 patients were available for radiological were assessed after injury, there were 56 male patients and 49 female patients in this study, the average age of the patients was 51 years old (ranged from 22 to 80 years). According to AO classification, there were 47 cases of type A2 and C1, and 58 cases of type A3, C2, C3. All patients were treated by closed reduction and below-elbow cast immobilization for 4 to 6 weeks. All patients were followed up for 3 to 6 months (means 4.5 months) by X-ray, all fractures were healed. Standard AP and lateral radiographic examination was conducted before reduction and after reduction and bony consolidation,the dorsal angulation and the radial angle were measured at each time point. The linear regression was used for the analysis to find out whether the final re-displacement can be predicted after primary reduction.

RESULTSAmong 105 patients,the significant correlations were found for the dorsal angulation between the reduction time and the end time (r = 0.82) and for the radial angulation between the reduction time and end time (r = 0.85).

CONCLUSIONThe dorsal angulation and the radial angulation after complete healing can be predicted from linear the regression functions. Due to the possibility of predicting the end result, whether the fracture should receive further conservative treatment or surgical treatment can be decided immediately.

The human basic Krüppel-like factor (hBKLF) is a newly cloned human transcription factor from the cDNA library of fetal liver. It belongs to the Krüppel-like transcription factor family. Previous expression study showed that it is a hematopoietic related factor. This study was aimed to investigate the effect of hBKLF on cell proliferation, differentiation and hemoglobin synthesis by using K562 cell line as model. The sense and antisense expression plasmids of hBKLF were constructed, and transfected into K562 cells by lipofectamine. After G418 selection for 4 weeks, the cell line with stable expression of the gene was obtained. Then the hBKLF expression level, proliferation ability, colony formation and hemoglobin production were detected by RT-PCR and Western blot, MTT method, methyl cellulose semisolid culture method and benzidine test respectively. The morphologic change of cell was observed with inverted microscope. The results showed that the sense plasmid could increase hBKLF level and antisense plasmid could decrease hBKLF expression. When hBKLF level was down-regulated, K562 cells could proliferate more quickly and synthesize more hemoglobin. But there were no differences in colony formation ability and no apparent morphologic change. It is concluded that hBKLF can inhibit hematopoietic cell proliferation and hemoglobin synthesis. It is suggested that hBKLF plays an important role in the proliferation and differentiation of hematopoietic cells.

OBJECTIVETo study the correlation between the expression of Egr-1 and NF-kappaB and the up-regulation of TNF-alpha and TGF-beta1 in macrophages after stimulation by silica in-vitro.

METHODSMacrophages were treated with antibodies against Egr-1 and NF-kappaB and antisense oligonucleotides. The level of TNF-alpha protein in the cell supernatant was then measured using enzyme-linked immunoadsorbent assay (ELISA). The expression of TGF-beta1 protein was detected by immunocytochemistry. The expression of TNF-alpha and TGF-beta1 mRNAs was also monitored by reverse transcriptase-polymerase chain reaction (RT-PCR).

RESULTSCompared with silica-stimulated macrophages untreated with antibodies, the cells treated with 10 micro g/ml of Egr-1 or NF-kappaB antibodies were associated with reduced expression of TNF-alpha and TGF-beta1 proteins and mRNAs (P < 0.05). Compared with silica-stimulated untransfected group, the antisense group was associated with obvious reduction in the expression of TNF-alpha and TGF-beta1 proteins and mRNAs (P < 0.05).

CONCLUSIONThe expression of TNF-alpha and TGF-beta1 mRNAs and proteins are associated with activation of Egr-1 and NF-kappaB in macrophages, after stimulation by silica. It is possible that the corresponding antibodies and antisense oligonucleotides may become a potential therapeutic tool in the management of silicosis in the future.

OBJECTIVECompared with Shengmai Capsule (生脉胶囊, SM), the study was conducted to evaluate the efficacy and safety of Xuefu Zhuyu Capsule (血府逐瘀胶囊, XFZY) on the symptoms and signs and health-related quality of life (HR-QOL) in the unstable angina (UA) patients with blood-stasis syndrome (BSS) after percutaneous coronary intervention (PCI).

METHODSA randomized, double-blinded, double-dummy, and placebo-controlled trial was applied. Ninety patients, diagnosed as UA and BSS after successful PCI, were enrolled and equally randomized into three groups, XFZY group, SM group, and placebo group, and administered with the corresponding medications respectively for four weeks. The clinical symptoms and signs (CSS), electrocardiography (ECG), and BSS scores were recorded and compared among groups during and after the treatment. Short-form 36 (SF-36) and Seattle Angina Questionnaire (SAQ) were applied to assess the HR-QOL in each group before and after the treatment. Safety indexes (blood routine and liver and kidney function tests) were also examined at the beginning and after the treatment.

RESULTSEighty-six patients completed the whole study. After the treatment, the total effective rates of the XFZY group in ameliorating CSS and ECG were 76.7% and 60.0%, respectively, which were obviously higher than those in SM (CSS: 53.3%; ECG: 36.7%) and the placebo (CSS: 43.3%; ECG: 30.0%) groups. After one week's treatment, BSS scores slightly decreased in each group, but no significant differences were found among three groups (P>0.05). After four weeks' treatment, BSS scores in the XFZY group decreased to a lower level compared with SM (P <0.05) and the placebo (P <0.01) groups. After the treatment, the efficacy of XFZY group in improving body pain (BP), general health (GH), vitality (VT), society functioning (SF), role emotional (RE), angina stability (AS), angina frequency (AF), and treatment satisfaction (TS) were better than those in the placebo group (P <0.05,P <0.01). Meanwhile, the dimensions of BP, GH, SF, AS, AF, and TS were better improved than those in the SM group P <0.05). No obvious adverse reaction was found during and after the treatment except one case in the XFZY group reporting of stomach discomfort.

CONCLUSIONSCompared with SM Capsule treatment, a short-term treatment with XFZY Capsule exhibits better efficacy on CSS and BSS scores, and HR-QOL in UA patients with BSS after PCI. However, its long-term efficacy and safety still needs further investigation.

OBJECTIVERecently, a new traditional Chinese medicine differentiation theory "Syndrome Element (SE)" has been raised. In this study, the main syndrome element types and their correlations with the results of coronary angiography (CAG) in patients with coronary heart disease (CHD) were investigated.

METHODSEpidemiology cross-sectional study method was employed and 324 patients with CHD were enrolled, and their syndrome element types as well as the CAG results were analyzed. The correlations among syndrome element types, Gensini score, and the number of abnormal branches were also analyzed based on the distribution characteristics of syndrome element and coronary angiography results in the 324 cases.

RESULTSAccording to their occurrence frequency in 324 CHD patients, the top eight major heart syndrome elements were Xin () blood stasis (85.8%), Xin qi deficiency (79.6%), Xin heat blockage (41.1%), Xin phlegm with turbid fluid (38.0%), Xin qi stagnation (24.7%), Xin yang deficiency (18.9%), Xin yin deficiency (17.5%) and Xin cold coagulation (4.4%), respectively, which suggested that Xin blood stasis and Xin qi deficiency were the two most common syndrome elements. Also, as coronary artery Gensini score increased, the changing trend of the syndrome element was "Xin yang deficiency with blood stasis" to "Xin phlegm obstruction with heat blockage" to "Xin yin deficiency with blood stasis" to "Xin qi deficiency with blood stasis" to "Xin cold coagulation with phlegm and turbid fluid, "Xin cold coagulation with blood stasis" to "Xin deficiency of qi, yin and yang". As the number of abnormal branches increased, the syndrome element changing trend was "simultaneous occurrence of cold and heat syndrome" to "Xin qi and yang deficiency with blood stasis" to "Xin retention of phlegm with turbid fluid" to "Xin cold coagulation in the heart meridian", "Xin deficiency of both qi and yin". The result of this study shows that Xin qi deficiency and Xin blood stasis were the major syndrome elements in patients with CHD.

CONCLUSIONAs the severity and extent of coronary artery lesion increased, there were some apparent correlations among syndrome elements, Gensini score and number of abnormal coronary artery branches.
