Modern Hospital 2015;15(5):22-24
Objective To investigate the inhibition of Sophora flavescens extract on the degree of inflammatory swelling of guinea pigs'skin with eczema, observe pathological changes and explore the effects of the anti-in-flammatory action, in order to provide experimental basis for clinical treatment.Methods Eczema models of 40 guinea pigs were set up by smearing 2, 4-dinitrochlorobenzene on their napes to cause sensitization and motivating in the inside of their right ears.All guinea pigs were randomly divided into 5 groups equally,including the model com-pared group, positive control group and high, medium, low concentration groups of sophora flavescens.After eczema skin was continuously administered drugs for 14 days, the same part with equal area of the left and right ears was taken and weighed.The difference between the left and right ears was used to evaluate the swelling degree of skin inflammation.The pathological changes were observed by making pathological slices with HE staining with the tissue blocks of right ears.Results Compared with the model group, the swelling degree of skin inflammation was significantly relieved and dermal edema and inflammatory cell infiltrating were significantly improved in the high and medi-um concentration groups of sophora flavescens (p<0.05).Compared with the positive group, the swelling degree of skin inflammation, dermal edema and inflammatory cell infiltrating were significantly alleviated in the high concentra-tion group of sophora flavescens ( p<0.05) .Conclusion Sophora flavescens extract can effectively reduce inflam-matory response of guinea pigs'skin with eczema, having a certain significance for the clinical treatment of eczema.

4.Protective effects of oxytocin on maternal aggression in stress model rats
Chinese Journal of Behavioral Medicine and Brain Science 2015;24(10):888-891
Objective To explore the effect of the different doses of oxytocin(OXT) on stress model aggressive behaviour in Wistar rats.Methods According to random number table,40 pregnant rats were divided into experimental stress groups (A, B, C) and control group(D) with 10 samples in each group.Before forced swimming test, rats in experimental groups (A, B, C)were given OXT via intraperitoneal injection with 0.3 mg/kg, 1.0 mg/kg,2.0 mg/kg;rats in group D were given equal volume of normal saline in the same way.At the 3rd day all rats were tested with maternal aggression,including mothers' following indices as total aggression times,biting times,pinning times,attack latency and duration of attack.Elevated plus maze (EPM) test was applied to analyze the behavioral changes.Results In terms of the duration of attack and attack latency,the indexes of group A and group D were significantly different from relevant data ((147.60±23.92) s and(79.70±9.88) s, P<0.05), while other indexes had no difference(P>0.05).The duration of attack and attack latency had a significant difference ((3.10±0.87) times, (13.60±5.14)times, (91.30±9.74)s and(167.20±30.02) s, P<0.01) between group B and group D except total aggression times(P>0.05).Group C and group D in given indexes had significant differences showing (6.40± 1.34) times, (15.10±4.35) times, (23.70±3.46) times, (49.80± 5.53) s and (215.60± 39.55) s (P<0.01).Group A and group B in given indexes had significant differences (P< 0.05);and group B and group C had a significant difference (P<0.01)except pinning times(P>0.05).In EPM ,the open arm entry ratio and the open arm time ratio of both group A and group D were significantly different from respective percentage (0.47±0.13) and (0.13±0.05) (P<0.01).The significant difference was found in group B and group D(P<0.01);group A and group B had a statistical difference(P<0.05);there was no difference in both groups in open arm time ratio(P>0.05).Conclusion Oxytocin potentially mediates maternal aggression by attenuating stress, and improves the intimate bonding between mother and pups,which means dose dependency of OXT in this process.
5.Report on discontinuation of tyrosine kinase inhibitor therapy and the cure of chronic myelogenous leukemia in the 54th ASH annual meeting
Journal of Leukemia & Lymphoma 2013;22(1):13-16
With the great success of imatinib mesylate(IM) and other tyrosine kinase inhibitor (TKI),chronic myelogenous leukemia (CML) is taken as a successful model of targeted therapies for human cancer.Although the emergence of TKI has greatly improved the prognosis of CML,the long-term TKI treatment may bring the problems of drug resistance,serious side effects,poor compliance,and heavy economic burden.Recently,people focus on whether patients would be cured after discontinuation of TKI treatment.Here,the progresses on discontinuation of TKI therapy in CML presented in the 54th American Society of Hematology (ASH) annual meeting were reviewed.
7.Domesitical botulinum toxin type A injection in the treatment of post-stroke patients with upper extremity spasticity
Chinese Journal of Neurology 2005;0(07):-
Objective To investigate the efficacy and safety of intramuscular injection botulinum toxin A (CBTX-A) made in China. Methods 43 post-stroke patents with upper extremity refractory spasticity were recruited in the study. The patients were randomly divided into two groups: injection combined with rehabilitation therapy (treatment group) and simple rehabilitation therapy (control group). CBTX-A was injected to the biceps brachii. The efficacy was assessed by modified Ashworth scale (MAS), range of motion (ROM),Fugl-Meyer Assessment-upper limb (FMA-upper limb) and motor-Functional Independence Measure-upper limb (mot-FIM-upper limb) at the baseline,2-week,4-week,8-week and 12- week after treatment by a physical therapist who was blind so as to which treatment they received. Results In the treatment group,85.7%(18/21) patients were benefited from the CBTX-A injection. Both groups improved on MAS,ROM,FMA-upper and mot-FIM-upper post-treatment. The score of MAS of treatment group were respectively 1.74?0.41,1.62?0.35,1.60?0.41 at weeks 2,4,8,while that of control group were respectively 2.50?0.51,2.27?0.53,2.18?0.55. The differences were significant(P0.05). After treatment,the ROM of treatment group were respectively 57.81?57.60,66.43?64.38,68.14?65.99 at 4,8, 12-week, and that of control group were respectively 27.91?30. 13,30.73?34.03, 33.73?34.50. The differences were significant (P0.05). Conclusion The result of the present study indicates CBTX-A injection combined with rehabilitation therapy decreases in local spasticity,enlarges the ROM of elbow joint. It is efficient,safe and well-tolerated. CBTX-A injection provides an additional alternative procedure for treatment of adult acquired refractory focal spasticity.
8.Effect of Ethyl Pyruvate on Expression of Caspase-3 in Hippocampus and Learning and Memory in Rats with Hypoxic Ischemic Brain Damage
Chinese Journal of Rehabilitation Theory and Practice 2016;22(4):409-412
Objective To investigate the effect of ethyl pyruvate (EP) on the expression of caspase-3 in the hippocampus and the learn-ing and memory ability in neonatal rats with hypoxic ischemic brain damage (HIBD). Methods 90 Wistar rats of 7 days old were randomly divided into sham operation group (n=15), HIBD group (n=15), EP1 group (n=15, 10 ml/kg), EP2 group (n=15, 30 mg/kg), EP3 group (n=15, 50 mg/kg) and EP4 group (n=15, 100 mg/kg). The model was established with Rice's method. 30 minutes before operation, and every 24 hours after operation, EP groups were injected with 10 ml/kg, 30 mg/kg, 50 mg/kg, 100 mg/kg EP in abdomen respectively, for 2 weeks. Af-ter treatment, the caspase-3 positive cells were observed by immunohistochemical staining, and the latency and the times crossing the target quadrant were tested by Morris water maze test. Results The caspase-3 positive cells were less in EP groups than in HIBD group (P<0.05), expect EP1 group (P>0.05), especially in EP3 group (P<0.01). The latency and the times crossing the target quadrant were better in EP groups than in HIBD group (P<0.05), expect EP1 group (P>0.05), especially in EP3 group (P<0.01). Conclusion Ethyl pyruvate can de-crease the expression of caspase-3 in hippocampus, and improve the ability of memory and learning in neonatal rats with HIBD.
