OBJECTIVE:To compare the efficacy,safety,vascular endothelial growth factor(VEGF)and matrix metallopro-teinase-2 (MMP-2) of docetaxel combined with carboplatin and paclitaxel combined with cisplatin (DDP) in the treatment of ad-vanced ovarian cancer. METHODS:120 patients with advanced ovarian cancer were randomly divided into docetaxel combined with carboplatin group(60 cases)and paclitaxel combined with DDP group(60 cases). Docetaxel combined with carboplatin group received 70 mg/m2 Docetaxel injection,intravenous infusion of 1 h,d1;50 mg/m2 carboplatin injection,intravenous infusion of 1 h,d2. Paclitaxel combined with DDP group received 135 mg/m2 Paclitaxel injection,intravenous infusion of 24 h,d1;30 mg/m2 DDP for injection,intravenous infusion,d3;60 mg/m2 Paclitaxel injection (a maximum of 2.0 m2) by intraperitoneal infusion,d8. 3-week was regarded as 1 treatment course,and it lasted 6 courses. Clinical efficacy,VEGF,MMP-2,progression-free survival, overall survival before and after treatment,mortality rate within 2 years of treatment and the incidence of adverse reactions in 2 groups were compared. RESULTS:There were no significant differences in the objective response rate,disease control rate,mortal-ity rate,incidence of adverse reactions between 2 groups(P>0.05). The progression-free survival in docetaxel combined with car-boplatin group was significantly longer than paclitaxel combined with DDP group,the difference was statistically significant (P<0.05). Before treatment,there were no significant differences in VEGF and MMP-2 level between 2 groups(P>0.05). After treat-ment,VEGF and MMP-2 level in 2 groups were significantly lower than before,and VEGF at different time points and MMP-2 level after 4 weeks,8 weeks and 12 weeks of treatment in docetaxel combined with carboplatin group were lower than paclitaxel combined with DDP group,the differences were statistically significant(P<0.05). CONCLUSIONS:Docetaxel combined with car-boplatin and paclitaxel combined with DDP shows similar efficacy and safety in the treatment of advanced ovarian cancer,but docetaxel carboplatin combined with is superior to paclitaxel combined with DDP in reducing VEGF and MMP-2 and improving pro-gression-free survival.

Objective To discuss clinical efficacy of patients treated with surgical treatment for posttraumatic elbow stiffness combined with pain.Methods From January 2011 to December 2014,release treatment was performed on 32 cases of posttraumatic contracture of the elbow combined with pain by operation.There were 22 males and 10 females,at average age of 39 years(range from 18 to 65 years).25 cases of these patients with mild-to-moderate pain got a simple elbow release operation.There were 4 cases of severe pain patients complicated with elbow dislocation,after fully release the elbows,reduction was performed under the direct;Both elbow arthrolysis and dermal transplantation interval type elbow arthroplasty were performed in 3 cases of severe pain patients which had severe osteoarthritis.A total of 26 patients were installed hinged external fixator after operation for early functional exercise.Results All patients were followed up for an average time of 14 months(from 12 to 18 months).All patients were significantly improved in the range of elbow and pain symptoms.Postoperative joint function improvement:2 patients with severe stiffness improved to moderate stiffness,19 patients with moderate or severe stiffness improved to mild stiffness,and the remaining of 11 cases without stiffness,The improvement rate was 100％.Postoperative pain:6 cases of moderate or severe pain relieved for mild pain,26 patients pain disappeared,the pain relief rate was 100％.Mayo elbow performance score were evaluated before and after surgery.Preoperative score:the results were good in 6 cases,fair in 14 cases and poorin 12 cases;postoperative score:excellent in 20 cases,good in 8 cases and fair in 4 cases,the good rate is 87.5 ％.The difference between preoperation and postoperation was statistically significant (P＜0.05).Conclusion Elbow arthrolysis combined external fixation is beneficial to early functional rehabilitation and restoring the flexion and extension function of stiff elbow,at the same time,the pain caused by stale dislocation or arthritis of elbow can also get good effect.
