Aim To investigate the expression of phosphorylated JNK1/JNK2 and the protection of 11,12-EET in ischemic and reperfusion rat heart.Method The expression of JNK1/JNK2 was detected with western blot method and the changing of heart function during ischemia/reperfusion process was observed in different groups. Results The cardiac function (+dp/dt_(max)%,-dp/dt_(max)% and LVDP)of reperfusion periods(30 min) apparently decreased in ischemia/reperfusion (I/R) group contrasted with Sham group, short ischemia(SI)+I/R group and EET+I/R group,and the expression of phosphorylated JNK1/JNK2 increased in I/R group contrasted with nromal group,Sham group and EET+I/R group.Conclusion The myocardial protection of 11,12-EET ( 6.24?10~(-8) mol?L~(-1)) is able to inhibit the expression of phosphorylated JNK1/JNK2.

Objective To explore the effects of levodopa and benserazide on upper extremity function after stroke. Methods 90 cases of sub-acute stroke patients were randomly divided into rehabilitation group (n=30), treatment group (n=30) and control group (n=30). The first 2 groups were treated with conventional movement therapy. The treatment group was treated with levodopa and benserazide tablet in addition.All patients were assessed with Fugl-Meyer assessment (FMA) and Motor Assessment Scale (MAS) before and 8 weeks after treatment.Results Before treatment, there was no significant difference in the scores of FMA and MAS among 3 groups (P>0.05). After 8 weeks treatment, the scores of FMA and MAS increased in the rehabilitation group and treatment group (P<0.05), the score was higher in the treatment group than in the rehabilitation group (P<0.05). Conclusion Levodopa and benserazide can further improve the functional performance of the upper extremities of stroke patients.

AIM: In order to study the relationship of the activation of ERK and delayed cardioprotection of 11,12-EET.METHODS: A rat ischemia/reperfusion(I/R) model was replicated by ligating left anterior descending coronary artery 30 min followed by 60 min.The expression of ERK was detected with Western blotting,and the change of heart function during reperfusion was observed.RESULTS: The difference of myocardial function was prominent at (24 h) in I/R group compared with sham group,EET+I/R and EET+PD098059+I/R group.The activity of ERK at(24 h) in EET+I/R group was higher than sham group, and the activity of ERK in EET+PD098059+I/R group was lower than that in EET+(I/R) group;the expression of phosphorylated ERK1/ERK2 at(24 h) in EET+I/R group was more than that in I/R group,and the expression of phosphorylated ERK1/ERK2 in EET+PD098059+I/R group was less than EET+I/R group.CONCLUSION: 11,12-EET has a delayed cardioprotection effect,and this protection effect is involved in the activity of ERK and expression of phosphorylated ERK1/ERK2.

Objective To investigate the effects of levodopa benserazide hydrochloride combine with dl-3-butyl phthalide capsule on patient's limbs function after stroke. Methods Ninety patients with stroke were randomly divided into rehabilitation group,treatment group and control group,and 30 cases for each group. Patients in rehabilitation group were treated with exercise therapy,in treatment group were given exercise therapy and levodopa Benserazide and Dl-3-butylphthalide capsules,and in control group were given placebo treatment. Adult hemiplegic motor function score(FMA)and motor function assessment scale(MAS)were used to assess the motor function and lower extremity function before treatment and 8 weeks after treatment. Results Before treatment,FMA and MAS in rehabilitation group,treatment group and control group were(22. 6 ± 3. 6), (23. 1 ± 2. 5)and(20. 3 ± 2. 9),and(1. 6 ± 0. 6),(2. 1 ± 0. 5),(1. 7 ± 0. 9),respectively. There was no significant differences between the two groups( F = 1. 64,P > 0. 05;F = 1. 66,P > 0. 05). After 8 weeks of treatment,FMA and MAS in rehabilitation group and treatment group were(60. 6 ± 3. 5),(14. 6 ± 1. 1),and (75. 7 ± 4. 5),(17. 7 ± 4. 5),significant improved more than that before treatment(t = 1. 738,1,716,1. 732 respectively;P < 0. 05). Meanwhile,patients in the treatment group improved more than that in rehabilitation group(P < 0. 05),and they were superior to patients in control group((31. 0 ± 3. 6),(5. 5 ± 1. 1);P < 0. 05). Conclusion Benserazide combined with dl-3- butyl phthalide capsule can further improve the limbs function.

In the pathophysiology experiment teaching,by combining the teaching of prob-lem-based learning with local area network(LAN) teaching,students first carry out a simple ex-periment to ask a question on the observed phenomenon,and then put forward a hypothesis,de-sign experiments to answer questions,and implement the experiment,and finally present experi-mental results.Such experimental design teaching is not only a great way to mobilize the stu-dents’interest in scientific research and learning initiative,but also greatly enhances the effi-ciency of the experiment.Students preliminarily master the basic scientific research program and methods.

Microperimetry is a procedure to assess retinal sensitivity while fundus is examined directly.It is a psychophysical method which is rapid,safe and non-invasive.It combines analysis of function and morphology and has an eye tracking system that can improve the fixation stability of patient with eccentric fixation and fixation instable.Microperimetry is supplement to visual function,perimetry,and other visual function parameters.As deepening of research,its clinical application value in ocular fundus diseases including age-related macular degeneration,diabetic retinopathy,retinitis pigmentosa,Stargardt's disease,macular hole,rhegmatogenous retinal detachment and central serous chorioretinopathy needs to be further explored.

Objective:To explore the application effect of co management mode in the prevention of perioperative venous thromboembolism (VTE) in elderly patients with hip fractures.Methods:Using the convenient sampling method, a total of 146 elderly patients with hip fractures who were admitted to the First Affiliated Hospital of Zhengzhou University from January to December 2019 were selected as the research objects. A total of 73 patients admitted from January to June 2019 were set as the control group and they were given routine venous thrombosis risk assessment, treatment, education and so on, while 73 patients admitted from July to December 2019 were set as the experimental group and they were given management according to co-management mode. The incidence of VTE, first out-of-bed activity time, hospital stays and expenses, awareness rate of VTE-related knowledge and level of DVT health belief were compared between the two groups.Results:After implementing the co management mode, the incidence of postoperative VTE in the experimental group was lower than that in the control group ( P<0.05) . The first out-of-bed activity time and hospital days in the experimental group were shorter than those in the control group, the hospital expense was lower than that in the control group, and DVT health belief score and VTE-related knowledge score were higher than those in the control group, and the differences were statistically significant ( P<0.05) . The scores of disease susceptibility, disease severity, health behavior benefits and self-efficacy in DVT health beliefs in the experimental group were higher than those in the control group ( P<0.05) . There was no statistically significant difference in the scores of obstacle and health motivation dimensions of healthy behaviors between the two groups ( P>0.05) . Conclusions:The application of co-management mode in elderly patients with hip fractures during the perioperative period can improve DVT health beliefs of patients and improve their VTE-related knowledge mastery, shorten the hospital stay, effectively prevent the occurrence of VTE and promote rapid recovery of patients.
