ABSTRACT
<p><b>OBJECTIVE</b>To investigate the application and effect of minimally invasive percutaneous anterior pelvic pubic ramus screw fixation in Tile B fractures.</p><p><b>METHODS</b>A retrospective review was conducted on 56 patients with posterior pelvic ring injury combined with fractures of anterior pubic and ischiadic ramus treated between May 2010 and August 2015, including 31 males and 25 females with an average age of 36.8 years old ranging from 35 to 65 years old. Based on the Tile classification, there were 13 cases of Tile B1 type, 28 cases of Tile B2 type and 15 cases of Tile B3 type. Among them, 26 patients were treated with sacroiliac screws combined with external fixation (external fixator group) and the other 30 patients underwent sacroiliac screw fixation combined with anterior screw fixation (pubic ramus screw group). Postoperative complications, postoperative ambulation time, fracture healing, blood loss, Majeed pelvic function score and visual analogue scale(VAS) were compared between two groups.</p><p><b>RESULTS</b>Fifty-four patients were followed up from 3 to 24 months with a mean of 12 months. There were no significant difference in the peri-operative bleeding and operation time between two groups(>0.05). The postoperative activity time and fracture healing time of pubic ramus screw group were shorter than those of the external fixator group, the differences were statistically significant(<0.05). The Majeed score, VAS score of pubic ramus screw group were higher than those of the external fixator group, the differences were statistically significant(<0.05). The incidence of postoperative complications of pubic ramus screw was lower than that of the external fixator group, the difference was statistically significant (<0.05).</p><p><b>CONCLUSIONS</b>Percutaneous iliosacral screws fixation combined with the pubic ramus screw is an effective and safty treatment method to the Tile B pelvic fracture. It has advantages of early ambulation, relief of the pain and few complications.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To observe the action of Chinese herbal preparation (CHP) on the recovery of nasal sinus mucosa after endoscopic sinus surgery (ESS).</p><p><b>METHODS</b>Seventy-eight patients (140 sinus) with chronic nasosinusitis and nasal polyps, who had undergone ESS, were divided into two groups. The 40 patients (70 sinuses) in the experiment group were treated with daily nasal flushing with diluted CHP while the 38 patients (70 sinuses) in the control group were untreated. Tissues of nasal mucosa were taken out from patients' posterior walls of maxillary sinus at different time points, i. e. 2 - 3 weeks, 8 - 11 weeks and 13 - 15 weeks after ESS were observed.</p><p><b>RESULTS</b>Significant difference was shown between the two groups under endoscope at all the time points in occurrence (patient/sinus) of sticky mucus, swelling and thickened mucus, occlusion of sinus opening, bloody secretion in sinus, and adhesion, etc. (P < 0.05, P < 0.01). Light microscopic examination showed significant difference between the two groups in occurrence (patient/sinus) of squamous epithelial metaplasia and fiber tissues proliferation (P <0.05). And electron microscopic examination also showed significant difference between the two groups in occurrence (patient/sinus) of inflammatory cell infiltration, fibers decrease, disordered arrangement, microvilli and short cilia (P<0.01).</p><p><b>CONCLUSION</b>Using CHP for postoperative nasal flushing after ESS is a safe and manageable approach with effects in promoting nasal mucosa recovery.</p>
