OBJECTIVE:To observe the clinical efficacy and safety of recombinant human endostatin (rh-endostatin) combined with Lobaplatin for injection and irinotecan injection in the treatment of advanced recurrent small cell lung cancer (SCLC). METHODS:A total of 88 patients with advanced recurrent SCLC in our hospital were divided into control group (41 cases) and observation group (47 cases) according to random number table. Control group was given Irinotecan injection+Lobaplatin for injection. Observation group was additionally given Recombinart human endostatin injection 15 mg added into 0.9%Sodium chloride injection 250 mL,ivgtt,qd,for consecutive 14 d,every 14 d. A treatment course lasted for 28 d,and both groups were treated for 2 courses. The clinical efficacy,the levels of serum carcinoembryonic antigen(CEA),the scores physical state (ECOG) and quality of life (QOL) before,after treatment were observed in the two groups,and the survival and adverse reactions of the two groups were compared. RESULTS:The total response rate of observation group was 59.6%,which was higher than 43.9% of control group,but there was no statistical significance (P>0.05). Before treatment, there was no significant difference in serum CEA levels,ECOG scores or QOL scores,between 2 groups(P>0.05);after treatment,the serum CEA levels of the two groups were significantly decreased,and the observation group was significantly lower than the control group,with statistically significant (P<0.05). In observation group,ECOG scores decreased while QOL scores increased significantly,and significantly better than the control group,with statistical significance(P<0.05). The overall survival(OS)of observation group was 16.8 months,which was significantly higher than 11.5 months of control group,with statistical significance (P<0.05). The incidence of leucopenia in observation group was significantly higher than control group;the incidence of leucopenia and abnormal liver function were significantly lower than control group,with statistical significance(P<0.05). CONCLUSIONS:Rh-endostatin injection combined with lobaplatin and irinotecan can improve serum CEA levels and the quality of living aswell as prolong the survival time.

OBJECTIVETo analyze the related factors of the infection after operation of open tibiofibula fractures.

METHODSThe clinical data of 141 patients with open tibiofibula fractures underwent surgical treatment from June 2009 to December 2012 were retrospectively analyzed. All the patients were male and aged from 18 to 61 years old with an average of 39.2 years; all the fractures were unilateral. According to Gustilo typing of fracure, 5 cases were type I, 44 cases were type II, 27 cases were type III a, 56 cases were type III b and 9 cases were type III c. These clinical data included patients' age, gender, body mass index (BMI), underlying diseases, time of operation, fracture site, fracture type, fixation method, postoperative drainage, debridement condition and so on. The postoperative infection conditions were recorded, and the correlation between above factors and infections were analyzed. Finally, the significant related variables were introduced into a Logistic regression model to evaluated their risk.

RESULTSAmong the 141 patients, 22 cases developed with infection (15.6%). The significant relative factors with infection contained fixation method, debridement condition, underlying diseases and postoperative drainage (P < 0.05). The correlativities were stepped up in order, their odds ratios value was 2.451, 3.164, 3.414, 5.117, respectively.

CONCLUSIONActive treatment for underlying diseases before operation, thorough debridement for open wound, suitable fixation method for fracture and thorough draining are effective measures in preventing postoperative infection.

OBJECTIVETo search all studies that had been published in the world with regarding to the effectiveness of the extent of intralesional curettage and wide excision for recurrence rate and complications and comparative functional outcomes in patients with giant cell tumours (GCT) of the distal radius and analyze them which were in high quality by means of Meta analysis, in order to give some evidences for the choice of method dealing with giant cell tumors GCT in surgery.

METHODSCochrane central register of controlled trials(Issue 8 2014), PubMed(1970-01-01/2013-01-01), Ovid (1970-01-01/2013- 01-01), Elsevier (1970-01-01/2013-01-01), CNKI (1970-01-01/2013-01-01) were searched. Including intralesional curettage and wide excision were performed to treat giant cell tumors (GCTs) of the distal radius in the literatures, selecting on meet eligibility in the standard literatures underwent strict quality assessment. The Meta-analysis was performed with software RevMan5.0 from the Cochrane collaboration. Additionally, the analysis checked the heterogeneity of data. The effectiveness of the extent of intralesional curettage and wide excision for recurrence rate and complication in patients with giant cell tumours of the distal radius were evaluated and Odds Ratio was calculated.

RESULTSSeven relevant articles were identified involving total 163 cases. Among them, 92 cases were intralesional curettage (PMMA, n = 54; bone graft, n = 33; no PMMA or bone grafts, n = 5) and 71 cases were wide excision. The patients in the intralesional curettage group had a higher recurrence rate [OR = 3.87, 95% CI (1.42, 10.53)],especially for Campanacci grade 3 GCTs [OR = 10.12, 95% CI (1.57, 65.27)], yet fewer major complications [OR = 0.13, 95% CI (0.04, 0.40)] than the wide excision group. The use of PMMA versus bone graft did not affect the recur- rence rate [OR = 0.96, 95% CI (0.26, 3.56)]. By selecting the system evaluation of MSTS, the VAS and dynamometer, the result showed that the intralesional curettage group was equivalent or preferable to wide excision in terms of function rehabilitation.

CONCLUSIONBased on data obtained from the limited number of studies available, intralesional curettage appears to be moreappropriate for the treatment of local lesions (Grade 1 and 2) than Grade 3 GCTs of the distal radius. Moreover, PMMA was not additionally effective as an adjuvant, the intralesional curettage group was found to be equivalent or preferable to wide excision in terms of function rehabilitation.
