Objective To analyze the effectiveness of conservative medical treatments for ectopic pregnancy (EP): methotrexate (MTX) + mifepristone + Ectopic Pregnancy II decoction (EP-II) vs. methotrexate + mifepristone. Methods A total of 95 patients with EP in Shenzhen Shajing Affiliated Hospital of Guangzhou Medical University from January 2009 to January 2011 were randomly divided into two groups: 45 patients in the experimental group were treated with MTX, mifepristone and EP II decoction, while the other 50 patients in the control group were treated with MTX and mifepristone. The effectiveness of the two groups was analyzed with SPSS 13.0 software. Results There were significant differences in the time of serum β-HCG return to normal (16.13±8.13 ds vs. 22.05±7.15 ds, Plt;0.05), time of EP mass absorption (30.46±7.56 ds vs. 39.99±18.26 ds, Plt;0.05) and tubal patency rate (80% vs. 75%, Plt;0.05) between the two groups. But there were no significant differences in effective rate (95.56%, 43/45 vs. 94%, 47/50, χ2=0.0809, Pgt;0.05) and side effects. Conclusion The combination of methotrexate, mifepristone and EP II decoction for ectopic pregnancy is more effective than mifepristone and methotrexate in coordinately killing the embryo, shortening the time of serum β-HCG return to normal and the time of EP mass absorption, and improving the function of oviducts.
Objective To investigate the effectiveness of posterior non-decompression surgery in the treatment of thoracolumbar fractures without neurological symptoms by comparing with the conventional posterior decompression surgery. Methods Between October 2008 and October 2015, a total of 97 patients with thoracolumbar fractures with intraspinal occupying 1/3-1/2 and without neurological symptoms were divided into the decompression surgery group (51 cases) and the non-decompression surgery group (46 cases). There was no significant difference in gender, age, cause of injury, injury segment, the thoracolumbar injury severity score (TLICS), combined injury, disease duration, and preoperative relative anterior vertebral height, kyphosis Cobb angle, intraspinal occupying percentage, visual analogue scale (VAS), Oswestry disability index (ODI), and Japanese Orthopaedic Association (JOA) score between 2 groups (P>0.05). The operation time, intraoperative blood loss volume, postoperative drainage, bed rest time, hospitalization time, and relative anterior vertebral height, kyphosis Cobb angle, intraspinal occupying percentage, and VAS score, ODI, JOA score at preoperative and postoperative 3 days and 1 year were recorded and compared. Results The operation time, intraoperative blood loss volume, and postoperative drainage in non-decompression surgery group were significantly less than those in decompression surgery group (P<0.05). There was no significant difference in the postoperative bed rest time and hospitalization time between 2 groups (P>0.05). In decompression surgery group, 4 cases had cerebrospinal fluid leakage and healed after conservative treatment. All incisions healed by first intention, and no nerve injury or infection of incision occurred. All patients were followed up 10-18 months (mean, 11.7 months). The recovery of vertebral body height was satisfactory in 2 groups, without secondary kyphosis and secondary nerve symptoms. The imaging indexes and effectiveness scores of 2 groups at 3 days and 1 year after operation were significantly improved when compared with preoperative ones (P<0.05). The intraspinal occupying percentage, VAS score, and ODI at 1 year after operation were significantly lower than those at 3 days after operation in 2 groups (P<0.05), and JOA score at 1 year after operation was significantly higher than that at 3 days after operation (P<0.05). Relative anterior vertebral height at 1 year after operation was significantly higher than that at 3 days after operation in non-decompression surgery group (P<0.05); and there was no significant difference in decompression surgery group (P>0.05). At 3 days, the intraspinal occupying percentage and JOA score in non-decompression surgery group were higher than those in decompression surgery group (P<0.05), and VAS score and ODI at 3 days in non-decompression surgery group were lower than those in decompression surgery group (P<0.05). No significant difference was found in the other indexes between 2 groups at 3 days and 1 year after operation (P>0.05). Conclusion Compared with the posterior decompression surgery, posterior non-decompression surgery has the advantages of less bleeding, less trauma, less postoperative pain, and so on. It is an ideal choice for the treatment of thoracolumbar fractures with intraspinal occupying 1/3-1/2 and without neurological symptoms under the condition of strict indication of operation.
