Objective To investigate the mRNA expression of ciliary n eurotrophic factor on the retina during injury and repair of optic nerves in rat s. Methods Thirty-five healthy SD rats were randomly divided into 3 groups: 5 in the control group, 15 in the simply transected optic nerve g roup and 15 in the optic nerve-sciatic nerve anastomosis group. The simply tran sected and optic nerve-sciatic nerve anastomosed models were set up, and the re tinal tissues of all of the rats were taken out after 3, 7 and 14 days, respecti vely; and the mRNA expression of CNTF in the 3 groups were observed by semi-qua ntitative reversal transcription-polymerase chain reaction method. Res ults A minimum expression of CNTF mRNA was found in the reti nae of the control group, and the increased rates of expression were found in th e retinae of the simple transection of optic nerve group with the increase rate of 100%, 594%, and 485% on the 3rd, 7th, and 14th day respectively after the ope ration, while in optic nerve-sciatic nerve anastomosis group, the increase rate s were found to be 258%, 752% and 515% on the 3rd, 7th, and 14th day respectivel y after the operation. Conclusion Retinal neurons can respond to axonal reaction of retinal ganglion cells by up-regulate endogenous CNTF aft er the injury of the optic nerves, which may provide a theoretic base for the application of the exogenous CNTF.

soda lime). It took significant less time to reach the peak CO concentration with baralyme than with the other two CO2 absorbents. The temperature of top canister went up faster than that of the bottom one with soda lime; whereas with baralyme the temperature of the bottom canister went up faster. Conclusion In a simulated closed circuit the risk of CO poisoning was higher with baralyme than with soda lime. But KOH-free soda lime which still contains NaOH, such as sofnolime, may produce more CO than standard soda lime.

HERG/IKr plays an important role in repolarization of cardiac action potential. In pathological condition such as cardiac ischemia, congestive heart failure and myocardial hypertrophy, the density and kinetic properties of HERG/IKr will change. This review is about modulation of HERG/IKr in pathological condition and effect of traditional chinese medicine on HERG/IKr.

The isolated working heart of guinea pig perfused with Tyrode's solution could work normally for at least 60 min. It was shown that berbamine ( BA ) could depress the function of isolated working heart of guinea pig in dose-dependent manner. BA 3 mol/L could decrease the left ventricular pressure, aortic pressure, -dP/dtmax, aortic blood flow and coronary blood flow, and increase left ventricular end-diastolic pressure. BA 100 mol/L could result in the ventricular asystole, however, no obvious influence the contraction of atrium.It was also demonstrated that BA could antagonise the arrhythmias induced by the adrenaline in isolated working heart of guinea Pig.

Objective To investigate the methods and effects of different flaps for repair of high energy injury-induced soft tissue wound of the heel.Methods From January 2002 to June 2012,the patients including 12 males and 9 females aged 18-57 years (mean,32 years) underwent heel soft tissue defect reconstruction.Causes of injury were traffic injury in 11 case and mechanical injury in 10 cases.Dimension of soft tissue defect ranged from 5 cm × 3 cm to 8 cm × 6 cm.Soft-tissue defect was repaired with sural neurovascular flaps at the posterolateral heel in 9 cases (Group A),with posterior tibial artery flaps at the posterolateral heel in 5 cases (Group B),and with medial plantar flaps at the loading area of heel in 7 cases (Group C).Sensory recovery and two point discrimination motion of the ankle joint were observed and compared among groups 12 month after operation.Heel pain was observed during weight bearing and joint activity was evaluated using the visual analogue scale (VAS).Results All the flaps survived,except for one with epidermal necrosis over the distal part,which healed after partial changing medication.Duration of follow-up was 12-24 months.There were no differences in the appearance,texture and contour between the flaps and recipient sites.Flaps showed no ulcer in the weight-bearing area and recovered their protective sense.Patients could walk normally after surgery.At postoperative 1 year,sensory recovery rate of the flaps in Groups A,B and C was 0,20% and 100% respectively (P <0.01).Appearance of the heel in all groups recovered to almost normal.Cases that could start nil weight-bearing exercise without pain accounted for 8 (89%) in Group A,4 (80%) in Group B,and 6 (86%) in Group C (P > 0.05).While heel pain existed in weight-bearing exercise.Difference in VAS was significant among the three groups (P < 0.05),but ankle range of motion was not (P >0.05).Conclusion Medial plantar flaps are suitable for tissue defect of 5-8 cm in length but sural neurovascular flaps and posterior tibial artery flaps should be considered for over 8 cm defect in order to elevate survival rate of the flaps and reconstruct limb function.

Objective To investigate the effects of Triptolide on apoptosis of cultured rat mesangial cells treated by TGF-β1 and the role of Smac in this process. Methods The mesangial cells were pre-treated with different concentrations of Triptolide for 24 hours, then stimulated with TGF-β1 for 24 hours. Apoptotic cells were detected by TUNEL assay. Smac transcription level was determined by Real time-PCR analyses. Smac expression level was assessed using Western blot anal-yses. Localization of Smac was shown by confocal fluorescence microscopy. Results Compared with control group, TGF-β1 inhibited apoptosis and Smac transcription and expression in rat mesangial cells. By contrast, Triptolide promoted mesangial cells apoptosis. In Triptolide groups, Smac mRNA and protein levels were up-regulated. Additionally, in normal and TGF-β1 groups Smac protein was mainly localized in mitochondriawhile in Triptolide groupit was mainly localized in cytoplasm and nucleus with increased fluorescence intensity. Conclusion Triptolide could promote the effect that TGF-β1 inhibited apop-tosis of mesangial cells, through both up-regulation the expression of Smac and stimulating it translocation from mitochon-dria to cytoplasm and nucleus.

Objective This study is to discuss the effects of cognitive therapy on life quality of rural breast cancer patients during chemotherapy in order to offer evidence for choosing the appropriate therapeutic measures.Methods 120 rural breast cancer patients were equally divided into the intervention group and the control group at random.The usual care plus cognitive treatment was given to the patients in the intervention group for 6 months,while only the usual care after chemotherapy was given to the control group.The quality of life assessments were carried out to both groups on the 5th day during hospitalization,and the first,third and 6th month during recheck period of time,respectively.The treatment effect was observed.Results There were statistical significant difference of the total scire of life quality assessment on the 5th day,the first,third and 6th month,respectively,between the intervention group and the control one after cognitive intervention.The downtrend of total score of quality of life in the intervention group after cognitive intervention was more significant than the control group,which indicated the quality of life of the intervention group was better than the control group. Conclusions Cognitive therapy is an efficient method to enhance the quality of life of rural breast cancer patients during chemotherapy.

Objective: To systematically review the association between apolipoprotein E (APOE) gene polymorphism and cerebral infarction in Chinese Han population. Methods: The pertinent literature of the gene polymorphism and the case control studies of cerebral infarction in Chinese Han population were researched comprehensively by combined application of 5 effective retrieval approaches. The odds ratio (OR) of the genotype distribution in cerebral infarction group and control group were calculated. Results: A total of 1986 patients with cerebral infarction and controls were included in the meta-analysis. After the data were pooled, the OR values of ApoE ε2/ε3, ApoE ε3/ε3, ApoE ε2/ε4, ApoE ε3/ε4, and ApoE ε4/ε4 were 0. 59 (95% CI, 0.44-0. 79), 0. 52 (95% CI, 0. 40-0.69), 2.00 (95% CI, 1.22-3.28), 2.77 (95% CI, 1.60-4.81 ), and 4. 66 (95% CI, 1.61-13.48), respectively. Conclusions: ApoE ε2/ε4, ApoE ε3/ε4 and ApoE ε4/ε4 genotypes are the risk factors of cerebral infarction. ApoE ε2/ε3 and ApoE ε3/ε3 genotypes are the protective factors of cerebral infarction.
