Objective To investigate the relationship between leukocyte counts and coronary artery stenosis as well as try to find the possible cause of coronary heart disease. Methods All the 220 patients underwent coronary angiography and leukocyte counts. The Gensini scoring system was used to determine the results of the coronary angiography. All patients were allocated into three groups according to the Gensini score. 74 cases with 0-3.00 score were classified into group CHD1 while 73 cases with 3.01-32.67 score were classified into group CHD2 and 73 cases with 32.68-180.00 score into group CHD3. The distribution of leukocyte counts in the three groups underwent analysis of variance and the relationship between leukocyte counts and the Gensini score was further investigated by means of multiple linear regression analysis. [WT5”HZ]Results The analysis of one way variance showed that neutrophil, monocyte and leukocyte counts were associated with the Gensini score. Multiple linear regression analysis adjusted for many risk factors for coronary heart disease showed that neutrophil counts had independent association with the Gensini score. Conclusion Neutrophil counts were independently associated with coronary artery stenosis.

HPLC fingerprint of Congrong Zonggan capsule was established in order to provide basis for quality evaluation. With acteoside as the reference, HPLC was adopted for fingerprint analysis on Congrong Zonggan capsule. The chromatographic conditions wereas follows. Waters C18 column (4.6 mm x 150 mm, 5 μm) was used, with methylalcohol-0.1% formic acid as the mobile phase for gradient elution at the flow rate of 1.0 mL x min(-1). The detection wavelength was 330 nm, and the column temperature was 30 °C. This method was highly accurate and reproducible. All of the 13 components in tested samples reached the baseline resolved peak, and 15 batches of finished products showed the similarity of above 0.95. The method was accurate and feasible and could be used as a simple and effective method to evaluate the quality of the traditional Chinese medicines.

OBJECTIVE To investigate the antibiotic resistance of Staphylococcus aureus isolates from the clinical samples from 2005 to 2007.METHODS The susceptibility tests and D-test were performed by the disk diffusion method and their results were analyzed by the software WHONET 5.4.RESULTS The rate of MRSA isolates accounted for 64.1%.The resistance rate to 12 kinds of the antimicrobial agents,such as penicillins,cephalosporins and carbapenems was 100%.The MRSA and MSSA were susceptible to linezolid and vancomycin.No isolates were resistant to vancomycin in our hospital;the positive rate of D-test was 78.7%.CONCLUSIONS MSSA is still sensible to most of the antimicrobial agents,but MRSA shows multidrug resistance.The D-test is of great clinical importance.

Zebrafish was selected as model animal, and glucocorticoid dexamethasone was used as a model compound to establish a rapid and high efficient osteopenia model. Zebrafish larvae at 4 days post fertilization (dpf) were exposed to a serial concentrations of dexamethasone solutions, and 0.5% DMSO was selected as the vehicle control group. All groups were incubated in 24-well plates (28.5 degrees C) until 9 dpf. In addition, effects of 10 micromol x L(-1) dexamethasone on preventing against osteopenia induced by etidronate disodium were also investigated. Zebrafish bones at 9 dpf were stained with alizarin red. Quantitative analysis of the stained area was performed by microscopic inspection and digital imaging methods to reflect the amount of bone mineralization. Results showed that dexamethasone group at 2.5, 10 and 25 micromol x L(-1) can decrease the staining area and the staining optical density values of zebrafish head bones when compared with the vehicle control group (0.5% DMSO), which suggested that dexamethasone can significantly reduce the zebrafish mineralized bone and the bone mineral density. Results also showed that 15 and 30 microg x mL(-1) etidronate disodium can increase the mineralized matrix of zebrafish head bone and prevent against osteopenia induced by dexamethasone. In conclusion, the study indicated that zebrafish can be an idea osteopenia model induced by dexamethasone.

Objective To evaluate the effect of ALD on podocyte apoptosis and the possible roles of Akt in ALD-induced apoptosis. Methods The cultured rat podocytes were incubated with increasing concentrations of ALD (10-9~10-5 mol/L) for variable time periods. Apoptosis was evaluated by cell nucleus staining and flow cytometry. RT-PCR was used to examine the expression of mineralocorticoid receptor (MR)and 11 Beta-hydroxysteroid dehydrogenase type 2 (11?-HSD2) mRNA in podocyte. Activation of Akt/PKB was evaluated by performing Akt kinase assay. Results ALD induced podocyte apoptosis in a dose- and time-dependent manner. The proapoptotic effect was attenuated by the presence of spironolactone (10-7mol/L). The expression of MR and 11P-HSD2 mRNA was demonstrated in the podocytes by RT-PCR. ALD also inhibited the activity of Akt in a dose-dependent manner, but the inhibitory effect was significantly ameliorated by the presence of spironolactone. The activity of Akt was negatively correlated with podocyte apoptosis. Conclusion ALD induces apoptosis in rat podocytes through the signaling mechanism by which Akt is inhibited.

BACKGROUND:Previously, serious thoracolumbar burst fractures with spinal cord injury were mainly treated by anterior surgery. The superiority of conventional posterior repair lies in strong reduction and fixation effects. However, it is difficult to fuly decompression. The anterior and central cylinders of the injured vertebra cannot receive good reconstruction. Loss of correction and internal fixation failure always appear. It remains controversial which repair method is more ideal. OBJECTIVE:To comparatively analyze the effect of posterior and anterior approaches with subtotal vertebrectomy, decompression, reconstruction of spine, and internal fixation for patients with thoracolumbar burst fractures. METHODS: The data of 42 patients with thoracolumbar burst fracture treated by anterior and posterior approaches with subtotal vertebrectomy, decompression, and reconstruction of spine from May 2006 to December 2012 was retrospectively analyzed. They were divided into two groups according to the surgical procedures: anterior approach group (n=23) and posterior approach group (n=19). They were folowed up for at least 24 months. Repair results and imaging results were compared in patients of both groups. RESULTS AND CONCLUSION:None patients in the two groups affected fixator loosing or breakage, and obtained good bone fusion. The intraoperative blood loss was more and operative time was longer in the anterior approach group than in the posterior approach group, showing significant difference (P < 0.05). The pulmonary function was significantly better in the posterior approach group than in the anterior approach group (P < 0.05). Visual Analog Scale score, Japanese Orthopaedic Association score for back pain and Frankel classification were significantly improved during final folow-up compared with pre-treatment in both groups, but no significant difference was found between groups (P > 0.05). No significant difference in the anterior vertebral height and kyphosis Cobb angle was detected before treatment, at 1 week after treatment and during final folow-up (P > 0.05). The incidence of postoperative complications was significantly higher in the anterior approach group than in the posterior approach group (P < 0.05). These findings confirm that subtotal vertebrectomy through anterior approach and posterior approach can effectively repair thoracolumbar burst fractures. However, the complications of posterior approach are less, and posterior approach has few impacts on the pulmonary function, is safe, and has good biocompatibility with the host.
