BACKGROUND:With the development of genetic engineering and tumor molecular biology, gene therapy has acted as a new treatment mode for tumors. OBJECTIVE:To investigate the impact of gene silencing ABCE1 on growth, proliferation and migration of human cervical cancer cel s XB1702. METHODS:siRNA sequences of ABCE1 were designed and synthesized to transfect XB1702 cel s using LipofectamineTM 2000. Cel s transfected with NC siRNA carrier served as controls, and untransfected cel s acted as blank group. After RNA interference, the expression of ABCE1 mRNA and protein was detected by western blod assay;cel cycle was detected using flow cytometry;cel counting kit-8 test, scratch healing assay and cel invasion assay were used to evaluate the effects of ABCE1 silence gene on XB1702 cel proliferation, migration and invasion ability. RESULTS AND CONCLUSION:ABCE1 mRNA and protein expression in the experimental group was significantly lower than that in the control group and blank group (P<0.05). Growth rate in the experimental group was significantly slowed, cel s were arrested in G 0/G 1 phase, and the number of S-phase cel s was reduced. Compared with the control group and blank group, XB1702 cel proliferation was inhibited significantly in the experimental group, and cel migration and invasion was significantly decreased (P<0.05). These results showed that specific interference with gene expression of ABCE1 can inhibit the migration of human cervical cancer cel s XB1702, and restrain tumor cel proliferation;therefore, the siRNA sequence of ABCE1 may be an effective target for treatment of cervical cancer.

Objective To study the distribution of rifampicin,isoniazid in tissues of patients with tuberculosis wrist for the sake of providing siven guide toward operation and postoperative chemotherapy.Methods 32 patients with tuberculosis wrist,according to radiographic data,were divided into Center group(group Ⅰ)and Borderline groups(group Ⅱ).All patients received chemotherapy regimen of 3SHR(T)Z/6HR(T).After treatment for4 weeks,the patients'specimen of serum,and tuberculosis tissues(group Ⅰ)including sclerotic bone wall,sub-normal bone and tuberculosis tissues(group Ⅱ)including dissolved bone wall,sub-normal bone were obtained during operation at 1,2 hours respectively after oral medication.Then pretreatment and mensuration using HPLC method were carried out after specimen's removal.Results Concentrations of isoniazid and rifapentine in(group Ⅰ)and(group Ⅱ)sub-normal bone and dissolved bone were abeve the minimal bactericidal concentration values.Concentration of 2 drugs in(group Ⅰ)sclerotic bone wall were much lower than that in sub-normal bone and dissolved bone wall.Conclusion The concentration of 2 drugs in patients sclerotic bone wall of wrist were too lower to eliminate the mycobacterium tuberculosis,while an effective concentration for anti-tuberculosis chemotherapy should be find in sub-normal bone and dissolved bone of wrist.Thus,the sclerotic bone of wrist plays an important role in obstructing the drags penetration into tuberculosis.

Objective To explore the effects of aerobic exercise on 6-minute walk distance and serum level of omentin-1 in maintenance hemodialysis (MHD) patients. Methods A total of 89 MHD patients (MHD group) in the 5th Central Hospital of Tianjin were included in the study from December 2013 to November 2014. Patients were randomly divided into two groups:routine treatment group (n=43) and aerobic exercise treatment group (aerobic exercise group, n=46). Fifty healthy subjects were selected as normal control group. Both groups received the same hemodialysis and regular treatments, and the aerobic exercise group received 6-month interdialytic aerobic exercise, and the routine group did not take any exercise intervention. The 6-minute walk distances (6MWDs),body mass,height and blood pressure were recorded, and serum levels of omentin-1, C-reactive protein (CRP), blood routine test and biochemistry test were determined in two groups. The relationship between 6 MWDs, age, CRP, left ventricular ejection fraction (LVEF) and omentin-1 were analyzed. Results The serum levels of omentin-1 and CRP weresignificantly higher, LVEF was significantly lower, in MHD group than those of healthy control group (P<0.01). After 6 months of aerobic exercise, 6MWDs, LVEF, hemoglobin and serum level of omentin-1 were significantly increased than those before treatment in aerobic exercise group. The 6MWDs, LVEF and hemoglobin were significantly increased after treatment than routine group. The levels of CRP, fasting glucose and blood pressure were significant decreased after treatment. The levels of CRP, fasting glucose and systolic blood pressure were decreased in treatment group than those of routine group. Before treatment, 6MWDs was negatively related with age and CRP, and positively related with LVEF and serum level of omentin-1 in MHD patients (r=-0.418,-0.229, 0.252 and 0.234, P<0.05). Conclusion Aerobic exercise can significantly increase values of 6MWDs, LVEF, hemoglobin and serum level of omentin-1, and reduce values of CRP, fasting blood glucose and systolic blood pressure in MHD patients. Aerobic exercise can improve physical performance,heart function and micro inflammatory state, thereby reduce cardiovascular events and mortality risk in MHD patients.

Objective: To investigate the effects of ischemic postconditioning and controlled low-pressure reperfusion on ischemia and reperfusion-induced spinal cord injury. Methods: Spinal cord ischemia was induced by occlusion of the descending thoracic aorta combined with maintaining systemic hypotension (40 mmHg,1 mmHg=0.133 kPa) in rats. Rats were randomly divided into three groups (n = 103), namely, control group, postconditioning group (Post-con group) and low-pressure reperfusion group (LR group). Rats in control group underwent an abrupt increase to 100 mmHg in mean arterial pressure (MAP) after reperfusion. Those in the Post-con group underwent 3 cycles of 30-second reperfusion and 30-second occlusion after 30-second full reperfusion with MAP of 100 mmHg. The MAP maintained 40 mmHg for the initial 3 min of reperfusion in the animals of the LR group, then increased to 100 mmHg. The relative spinal cord blood flow (rSCBF) was monitored simultaneously during the ischemia and 30 min after reperfusion. The activities of superoxide dismutase (SOD),catalase (CAT) and myeloperoxidase (MPO) and malondialdehyde (MDA) content in lumbar spinal cord tissue were measured at 1,4,12 and 24 h after reperfusion,and the neurologic function of hind-limb was also evaluated at the same time. The samples of lumbar spinal cord were collected in all groups at the end of observation for histological examination. Results: Postconditioning and low-pressure reperfusion both improved the hyperperfusion after reperfusion. In Post-con group the activities of SOD and CAT was markedly increased 1 and 4 h after reperfusion (P<0.01) compared with control group, and no marked increase in MDA and MPO was observed. The MDA in the spinal tissue of LR group was significantly lower than that of the control group (P< 0.01), but no significant increases were observed in the activities of SOD and CAT. The MPO activity in LR group peaked from the 1st to 4th hour of reperfusion and then gradually reduced. Postconditioning and low-pressure reperfusion both improved the neurologic function during reperfusion, but behavioral scores of animals in LR group were lower than that in the Post-con group. The pathological results had a similar pattern to the behavioral scores in all 3 groups 24 h after reperfusion. Conclusion: Ischemic postconditioning and controlled low-pressure reperfusion can both attenuate ischemia and reperfusion injury in spinal cord, and the neuroprotection of ischemic postconditioning is superior to controlled low-pressure reperfusion, probably because postconditioning can enhance activities of antioxidant enzymes and decrease neutrophil accumulation.
