Objective To evaluate the role of nicotinamide adenine dinucleotide phosphate oxidase (NADPH oxidase) in the spinal cord in the maintenance of diabetic neuropathic pain in rats.Methods Pathogenfree male Sprague-Dawley rats,aged 2 months,weighing 180-220 g,were used in the study.Diabetes mellitus was induced by intraperitoneal streptozotocin (STZ) 60mg/kg and confirmed by blood glucose ＞ 16.7 mmol/L at 72 h after STZ injection.Twenty diabetic rats were randomly allocated to diabetic neuropathic pain group (DN group,n =10) and apocynin (specific NADPH oxidase inhibitor) group (A group,n =10).Another 10 agematched normal rats served as control group (C group,n =10).Twenty-eight days after STZ injection,apyconin 5 mg/kg was injected intraperitoneally once a day for 7 consecutive days in A group.Paw withdrawal threshold to yon Frey filament stimulation (PWT) was measured before STZ injection (T1) and at 7,14,21,28 and 35 days after STZ injection (T2-6).The rats were sacrificed after PWT was measured at T6 and L4.5 segments of the spinal cord were removed for determination of NADPH oxidase subunits gp91phox and p47phox expression,MAD content and SOD activity.Results Compared with C group,PWT was significantly decreased at T3-5,gp91phox and p47phox expression was up-regulated,MAD content was increased,and SOD activity was decreased in DN and A groups.Compared with DN group,PWT was significantly increased at T6,gp91phox and p47phox expression was downregulated,MAD content was decreased,and SOD activity was increased in A group.Conclusion NADPH oxidase in the spinal cord is involved in the maintenance of diabetic neuropathic pain in rats.

Objective To explore the effect of contract learning on rehabilitation training to patients with stroke . Methods According to the random number table, 120 stroke patients were randomly divided in equal number into control group and observation group. The patients in the control group were treated with conventional nursing during hospitalization and health guidance during follow-up. The patients in the observation group were given rehabilitation training according to contracted learning during the period of hospitalization and follow-up. The time was 6 months. The quality of life was compared between the two groups of patients before and after the intervention, 1 months after discharge, 6 months after discharge. Results After six months of intervention, the 7 dimensions of quality of life, including daily life ability, hand function, mobility, strength, emotion, communication and participation in the intervention group were significantly better than those of the control group (P<0.001). The 6 dimensions of quality of life, including daily life ability, hand function, mobility, strength, emotion, and communication of the control group were significantly better than before the intervention (P<0.001). Conclusion For stroke patients, the rehabilitation training under the learning contract can improve the effect of rehabilitation training so as to improve the quality of life and the prognosis.

OBJECTIVETo study the effect of the synthetic peptide RGDSY-CTTHWGFTLC on the biological behavior of breast cancer MCF-7 cells in vitro.

METHODSMCF-7 cells were incubated with different concentrations of the synthesized peptide RGDSY-CTTHWGFTLC (RGDSY-CTT), the positive control peptide CTTHWGFTLC (CTT), or the negative control peptide STTHWGFTLS (STT) in fibronectin-coated 96-well plates for different time lengths, and the changes in cell adhesion, invasiveness, proliferation, apoptosis and cell cycle were detected using Transwell chamber assay, MTT assay, and flow cytometry.

RESULTSIncubation of the cells with 50, 100 and 200 µg/ml of RGDSY-CTT caused a significant concentration- dependent inhibition of the cell adhesion (cell adhesion rates of 85.1%, 74.1% and 63.8%, respectively) with stronger effects than CTT (P<0.05). At 100 and 200 µg/ml, RGDSY-CTT significantly inhibited the invasion (with inhibition rate of 41.8% and 63.9%, respectively) of MCF-7 cells with an effect similar to that by CTT (P>0.05). At 50, 100 and 200 µg/ml, RGDSY-CTT concentration-dependently suppressed MCF-7 cell proliferation (with cell proliferation rates of 98.8%, 82.4% and 63.0%, respectively), and this inhibitory effect was stronger than that of CTT at 100 and 200 µg/ml (P<0.05). The results of flow cytometry also demonstrated a stronger apoptosis-inducing effect of RGDSY-CTT (76.7%) than that in CTT, STT and the blank control groups (P<0.05).

CONCLUSIONSRGDSY-CTT can inhibit cell invasion, suppress adhesion and proliferation, and induce apoptosis in MCF-7 cells.
