OBJECTIVENimotuzumab is a humanized monoclonal antibody targeted against epidermal growth factor receptor (EGFR). Recent clinical studies show that patients with malignant gliomas could benefit from nimotuzumab treatment. The aim of the present study was to evaluate the efficacy and side effects of nimotuzumab in combination with chemotherapy for patients with malignant gliomas.
METHODSThe patients received 200 mg of nimotuzumab infusion intravenously over 60 minutes once weekly for the first eight weeks and then once every two weeks until unacceptable toxicity or tumor progression occurred. Individualized chemotherapy was administered based on O(6)-methylguanine-DNA methyltransferase (MGMT) expression and previous chemotherapy responses in combined with nimotuzumab.
RESULTSFourteen patients received a total of 122 times of nimotuzumab ranging from 2 to 20 (median 7.5 times). Combined chemotherapy regimens included: continuous 21-day temozolomide (10 cases), standard 5-day temozolomide (2 cases), teniposide plus cisplatin (1 case), and teniposide plus nimustine (1 case). Partial response (PR) and stable disease (SD) were found in 3 patients (21.4%)and 6 patients (42.9%), respectively. Disease control rate (PR + SD) was 64.3%. The median progression-free survival (PFS) was 4 months (95%CI: 0.7 - 7.3) and PFS at 6 months was 30.6%. The most common toxicities include grade I-II neutropenia (2 cases), thrombocytopenia (2 cases), lymphopenia (1 case), nausea and vomitting (3 case) and asymptomatic transaminase increase (1 case). One patient developed grade IV neutropenia and thrombocytopenia. One patient developed nimotuzumab-related acneiform rash.
CONCLUSIONSNimotuzumab in combination with chemotherapy has moderate activity in patients with malignant gliomas and the toxicities are well tolerable, therefore, worth further investigation.

AIMTo investigate the alterations of taurine transport, and taurine transporter (TAUT) mRNA by hyperglycemia in cultured rat cardiomyocytes.
METHODS3H-taurine measured the amount of taurine uptake. TAUT mRNA consents were measured using quantitative RT-PCR.
RESULTSThe cellular uptake amounts of taurine in seven groups increased with incubation time, and near to be saturated after 5 min. The uptake amount of 10, 20, and 30 mmol/L glucose groups was obviously lower than that of the control group (P < 0.05 or P < 0.01). In 30 mmmol/L glucose, taurine release obviously was decreased, as compared with that of the control. Exposure of cells to 10, 20, and 30 mmmol/L glucose decreased taurine uptake in a concentration-dependent fashion. Exposure to hyperglycemia did not affect the Km of the TAUT, but the apparent Vmax were significantly decreased (P < 0.05). In 20 and 30 mmmol/L groups, TAUT mRNA contents of myocardial cells were significantly reduced, as compared with the control group (P < 0.05).
CONCLUSIONThe data suggests that there are dysfunction of taurine uptake and downregulation of TAUT gene expression by glucose in cultured rat cardiomyocytes.

OBJECTIVETo evaluate the clinical effects by comparing three different fixation methods: tension band, hollow lag screw and anatomical plate.
METHODSFrom January 2010 to January 2012, 82 patients with olecranon fractures who underwent surgical treatments were followed-up. All the patients were divided into three groups: tension band fixation group (group A), hollow lag screw fixation group (group B), anatomical plate fixation (group C). In group A, there were 35 patients, including 19 males and 16 females, ranging in age from 32 to 49 years old, with an average of (43.6 ± 8.7) years old, and the patients were treated with tension band fixation. According to Colton classification, there were 5 cases of type I, 3 cases of type II A,19 cases of type II B, and 8 cases of type II C in group A. Among 20 patients in group B, there were 13 males and 7 females, ranging in age from 27 to 50 years old, with an average of (41.5 ± 9.3) years old. The patients in group B were treated with hollow lag screw fixation. According to Colton classification, there were 4 cases of type I, 4 cases of type II A, and 12 cases of type II B in group B. In group C, there were 27 patients totally, including 15 males and 12 females, ranging in age from 30 to 55 years old, with an average of (38.2 ± 6.2) years old. The patients in group C were treated with anatomical plate fixation. According to Colton classification, there were 4 cases of type II B, 13 cases of type II C, and 10 cases of type II D in group C. The Fracture healing time, complications and functional recovery were retrospectively observed and recorded.
RESULTSAll the patients were followed up, and the duration ranged from 8 to 24 months, with an average of 15 months. The average healing time of patients in group C was the longest among three groups. The flexion-extension and rotation activities of elbow joint in group B and C were better than that in group C. According to Broberg & Morrey score system, the therapeutic effects of patients in group A and B were better than that of group C. In group C, 2 patients had incision infections, 6 patients complained of foreign body sensation, 1 patient got a delayed fracture healing, and 1 patient had the heterotopic ossification. There were no occurrences of incision infections in group A and B; internal fixation loosening occurred in 3 patients in group A and 2 patients in group B; delayed fracture healing occurred in 2 patients in group A and 2 patients in group B; and skin bursa formation occurred in 6 patients in group A and 1 patient in group B.
CONCLUSIONAll the three ways are effective methods for the treatment of olecranon fractures. Fixation methods should be selected depending on the type of fracture.

OBJECTIVETo evaluate medium-long term patency of below-knee bypass on patients who suffered from diabetic lower limb ischemia.
METHODSClinical and follow-up data of 51 patients was retrospectively analyzed who underwent 56 below-knee bypass because of diabetes from November 2001 to December 2006. There were 35 male and 16 female with an average age of 68 years. They endured 26 months ischemic time lag in average, and had suffered from diabetes for 11 years. All of the patients were performed bypass to below-knee (posterior tibial, anterior tibial or peroneal) arteries. Kaplan-meier method was applied. The subgroups of different operative methods and different out-flow vessels were compared by Log-rank tests.
RESULTSAn average follow-up time of 23 months was achieved, and lost-follow-up rate was 15%. The total 1- and 5-year primary patent rates were 68% and 54% respectively, secondary patent rate were 70% and 60% respectively, limb salvage rates were 69% and 65%, survival rates were 82% and 60%. One year (3 years) of patent rate(s) of operative method subgroups of femoral-popliteal-infrageniculate bypass with composite grafts, femoral/popliteal-infrageniculate bypass with artificial grafts and femoral/popliteal-infrageniculate bypass with autologous veins were 70% (50%), 33% (33%) and 70% (70%) respectively. One year (4 years) of patent rate(s) of out-flow vessel subgroups of posterior tibial artery, anterior tibial artery and peroneal artery were 65% (60%), 80% (53%) and 77% (66%) respectively. However, both subgroups did not show any statistic differences by log-rank tests.
CONCLUSIONSPartial or whole autologous veins as bypass grafts should be chosen when infrageniculate bypass is considered in diabetic patients. Considerable patent rates are acceptable no matter what kinds of out-flow vessels are chosen.
