Diabetic patients with secondary sulfonylureas failure were shifted to glipizide plus glargine ( n = 20) or neutral protamine hagedorn (n =32). Sixteen weeks later, blood glucose and HbAIC were decreased and serum C peptide level increased in both groups. Hypoglycemia occurred less frequently and?-cell function was improved in glargine group.

Objective To develop an interlocking-style vascular shunt device for the treatment of distal limb ischemia resulting from vascular disconnection and defect.Methods A one-way interlocking buckle was designed with the space between the clamping teeth being 0.5 mm,which prevented the device from moving backwards and fixed the vessel and shunt tube conveniently.The interlocking buckle combined with silicone tube was used to connect the two ends of the defected vessel,which was compared with conventional method by suture ligation and silicone tube by the tests on vessel bursting pressure and tensile biomechanics.Results The vessel repaired with the developed device behaved better than that by the conventional method in the tests on vessel bursting pressure and tensile biomechanics (P＜0.05).Conclusion The vascular shunt device can be used for the treatment of distal limb ischemia resulting from vascular disconnection and defect,and thus facilitates the vascular graft in rear hospital after evacuation.

ObjectiveTo investigate the radiosensitizing effect of 3-(5'-hydroxy-2'-furyl)-1-benzyl indazole ( YC-1 ) on hypoxic human adenocarcinoma cell line A549.MethodsMTT assay was used to test the inhibitory effect of YC-1 on proliferation of A549 cells.Clonogenic assay was performed to determine the radiosensitizing effect of YC-1 on hopxic A549 cells.Single-hit multi-target model was used to plot survival curve and calculate sensitization enhancement ratio (SER).The cell cycle and apoptosis were measured by flow cytometry.ResultsThe proliferation of A549 cells was inhibited by YC-1 in a time-dose-dependent manner.In normoxic and hypoxic cells,the IC20 was 16.7 μmol/L and 39.2 μmol/L at 24 h,respectively.In the group of hypoxia plus YC-1,SERD0 and SERDq were 1.11 and 1.26,respectively.In hypoxia,YC-1combined with 2 Gy irradiation could induce cell apoptosis and prolong G2 + M phase arrest ( ( 30.17 ±1.21 )％ ∶ ( 15.44 ±0.96) ％,P =0.000; (21.56 ±0.47 )％ ∶ (6.16 ±0.16)％,P =0.000).Concinsions YC-1 could enhance the radiosensitivity of hypoxic A549 cells.

Objective To investigate the therapeutic effects of recombinant human endostatin (RHES) combined with radiotherapy on brain metastases (BM) of non-small cell lung cancer (NSCLC) and the patients suitable for this therapy.Methods Eighty patients with BM of NSCLC were randomly divided into RHES combined with radiotherapy group (combination group) and radiotherapy alone group (each group with 40 patients).The short-term effective rate,overall survival time,cerebral edema index and adverse reactions were observed and the expressions of vascular endothelial growth factor receptor 2 (VEGFR2) protein in primary lesions were detected with immunohistochemical method in all patients.Results Compared with radiotherapy alone group,brain edema was significantly relieved (t=4.9,P=0.000) and there were no marked adverse reactions in combination group.In short-term effective rate,there was no statistical significance in total population (n=80,90％ vs.75％,x2=3.11,P=0.07),but there was statistical significance in the patients with positive VEGFR2 (93％ vs.67.7％,x2=6.31,P=0.012).In overall survival time,there was no statistical significance in total population (n=80,P=0.35,95％ CI:0.25-1.30) or in the patients with positive VEGFR2 (P=0.109,95％ CI:0.40-1.34).Conclusion Compared with radiotherapy alone,RHES combined with radiotherapy can relieve brain edema in the patients with BM of NSCLC and obtain better short-term effective rate in the patients with positive VEGFR2.

Objective To investigate the effects of ozone (O3) on Wnt/β-catenin signaling pathway in the articular cartilage of rats with osteoarthritis (OA).Methods Eighteen male SPF Wistar rats,aged 3 months,weighing 200-250 g,were randomly divided into 3 groups (n =6 each) using a random number table:control group (group C),group OA,and O3 group (group O).OA was induced by injection of monosodium iodoacetate 3 mg (50 μl) into the right knee joint cavity.On 7th day after the model was established successfully,25 μg/ml O3 1 ml were injected into the knee joint cavity,once a week for 3 consecutive weeks in group O.Behavioral changes were observed after establishment of the model.At 1 day before establishment of the model,and 1,4,7,14,21 and 28 days after establishment of the model,the mechanical paw withdrawal threshold (MWT) was measured.At 28 days after establishment of the model,the total knee joint was removed and stained with haematoxylin and eosin for examination of the pathological changes of the cartilage (under light microscope) and for determination of the expression of β-catenin and matrix metalloproteinase-13 (MMP-13) in the cartilage (by immunohistochemistry).Results The signs of OA such as hind-limb motor dysfunction,knee joint swelling,or decreased joint motion,and signs of hyperalgesia such as lickings were observed after establishment of the model in rats.Compared with group C,the MWT was significantly decreased at each time point after establishment of the model,and the ex pression of β-catenin and MMP-13 in the cartilage was significantly up-regulated in the other two groups(P＜0.05).Compared with group OA,the MWT was significantly increased at 7-28 days after establishment of the model,and the expression of β-catenin and MMP-13 in the cartilage was significantly down-regulated in group O (P＜0.05).The pathological changes of the cartilage were significantly reduced in group O as compared with group OA.Conclusion The mechanism by which O3 mitigates OA is probably related to inhibition of Wnt/β-catenin signaling pathway activation in the articular cartilage in rats.

Objective To analyze CT and MR features of malignant peripheral nerve sheath tumor (MPNST)of children. Methods Sixteen patients with histologically proven MPNST were retrospectively reviewed.There were 8 male and 8 female, ages from 0.3 to 11.0 years, and median age was 2.5 years. Sixteen cases were performed with CT plain scan, and eight cases with CT enhancement scans, and three with MR examination. The imaging data were analyzed by two highly experienced doctors and obtained agreements after mutual consultation. Results Among 16 cases, 3 cases were located at neck, 5 cases at waist and back,3 cases at abdominal and pelvic, 2 cases at foot, 1 case at left clavicle, 1 case at right mediastinum, 1 case at right orbit. Fifteen cases appeared as solid masses and 1 case showed a diffuse growth. CT plain scan showed 8 cases were solid-appearing masses and 7 cases were cystic-solid mass. Enhanced CT showed enhancement of solid component was moderate to marked and gradually delayed enhanced while cystic component had no any enhancement. One was located on the left side of the neck and appeared as diffuse growth. Two cases of solid mass type appeared as hypo-intensity on T1WI and hyper-intensity on T2WI, and obviously high signal intensity of cystic component on T2WI, and with significantly heterogeneous enhanced.One case with diffuse growth appeared as hypo-intensity on T1WI and slightly hyper-intensity on T2WI, and with significantly enhanced. Sixteen cases appeared as invasive growth, 11 caseswith multiple organic metastases and recurrences, and 4 cases with neurofibromatosis type I and scoliosis.Conclusion CT and MR appearances of MPNST have certain characteristic features, and can demonstrateaggressive performance and multiple organic metastases, which is helpful for definite diagnosis and treatment plan.
