Résumé

Objective To compare the effectiveness of arthroscopy assisted percutaneous internal fixation and open reduction and traditional surgery tibial plateau fractures.Methods From August 2013 to April 2014, 78 patients with tibial plateau fractures according to random number table were divided into group A and group B, 39 cases in each. A group of traction using arthroscopic surgery, group B with traditional open bag reduction surgery.Results The operation time, intraoperative and postoperative bleeding less and wound lesion area was shorter and less in group A than that in group B; while the healing time and HSS score was faster and higher than that in group B. The difference was statistically significant (P 0.05); postoperative complication rate in group A was lower than that in group B, and there is significant difference (P < 0.05).Conclusion Both treatment methods can achieve good clinical results, but arthroscopically assisted treatment of tibial plateau fractures reset shorter operative time, less blood loss, healing time is shorter, less complications, but higher HSS score, etc., which reduced the suffering of patients and improved the outcome.

Résumé

<p><b>OBJECTIVE</b>To investigate the effect of salvianolic acid B (SAB) on the proliferation of human embryonic lung fibroblast MRC-5, and the secretion of procollagen I and endogenous transforming growth factor-beta1, (TGF-beta1).</p><p><b>METHODS</b>The MRC-5 cells were randomly divided into four groups as follows: the control group: cells cultured with DMEM but with no TGF-beta1, or SAB; the TGF-beta1, group: cell cultured with 10 ng/mL TGF-beta1; the SAB1 group: cell cultured with medium with 10 ng/mL TGF-beta1 and 1 pmol/L SAB; the SAB2 group: cell cultured with medium with 10 ng/mL TGF-beta1, and 10 pmol/L SAB. The proliferation of cells was assayed by MTT incorporation. The concentration of amino-terminal propeptide of type I procollagen (PINP), a marker of collagen synthesis, was measured by radioimmunoassay. The endogenous TGF-beta1, levels were measured using ELISA.</p><p><b>RESULTS</b>The optical density, procollagen I contents, and endogenous TGF-beta1, levels significantly increased when compared with those of the control group (P<0.05). Compared with the TGF-beta1, group, the optical density was obviously lowered, the procollagen I contents and endogenous TGF-beta1, levels significantly decreased in the SAB1 group and the SAB2 group, and better in the SAB2 group, showing statistical difference (P<0.05).</p><p><b>CONCLUSIONS</b>SAB could inhibit the proliferation of MRC-5 cells induced by TGF-beta1 and attenuate the roles of secreting collagen and endogenous TGF-beta1. It had the potential of postponing or delaying the progressive developing of pulmonary fibrosis.</p>

Résumé

To increase drug concentration in the head through intranasal administration, we have investigated the excised animal nasal mucosa permeability and nasal toxicity of the baicalin drug carrier systems, such as baicalin liposomes, beta-cyclodextrin inclusion compound, and phospholipid complex. A transport of baicalin drug carrier systems through nasal mucosa was simulated in diffusion chamber in vitro, and swine, caprine and rabbit nasal mucosa was used, the concentration of drug in the receptor was determined by HPLC. By taking the apparent permeability coefficients as evaluation standard, investigated the isolated animal nasal mucosa permeability of different baicalin drug systems was investigated for screening the best baicalin drug carrier system through nasal cavity administration. Toxicity of baicalin and its phospholipids complex on toad palate mucosal cilia movement and rats nasal mucosa long-term toxicity were studied in vivo. The apparent permeability coefficient of three kinds of baicalin drug carrier systems was better than that of baicalin (P < 0.05), and its lag-time was obviously shortened. At the same time, the apparent permeability coefficient of phospholipid complex was higher than those of other two drug carrier systems (P < 0.05). The results showed that the baicalin phospholipids complex nasal mucosa permeability was obviously superior to the other two drug systems. Baicalin phospholipids complex had no toxicity to ciliary movement, and had no irritation to rat nasal mucosa. The results show that baicalin phospholipid complex was the best baicalin drug carrier system, it could significantly enhance the permeability of baicalin across nasal mucosa, had no toxicity to nasal mucosa, and could be used for intranasal administration.

Résumé

<p><b>OBJECTIVE</b>To introduce diagnosis and treatment of the metacarpophalangeal joint (MPJ) locking caused by sesamoid turned-over dislocation of the thumb.</p><p><b>METHODS</b>Five cases with metacarpophalangeal joint locking were involved in the study, male 4 and female 1. The average age was 35 years old(ranging from 18 to 47 years). All the patients received manual reduction under local anaesthesia. But only three were successful, others patients were reduced by operation. Metacarpophalangeal joint locking caused by sesamoid turned-over dislocation with the volar plate and the short flexor muscle of the thumb tendon were reveded. The metacarpophalangeal joint locking was released after reduction of sesamoid turned-over dislocation of the thumb.</p><p><b>RESULTS</b>The mean follow-up time was 15 months (3-34 months). The mean range of MPJ flexion was 45 degrees (35 degrees - 60 degrees). The signs for pain and swelling were released. Satisfactory thumb opposition can be seen.</p><p><b>CONCLUSION</b>It was one of the important reasons of the metacarpophalangeal joint locking caused by sesamoid turned-over dislocation of the thumb.</p>
