Cerebral ischemia activates endogenous angiogenic factors,and increase microvessel density and form new capillaries in ischemic brain tissues.Exogenous angiogenic factors can more effectively promote angiogenesis and the establishment of collateral circulation in ischemic regions and peripherial tissues,improving local blood supply and reducing infarct size.The further study of the mechanisms and methods in promoting regional angiogenesis after cerebral ischemia will contribute to improve neurologic deficit.

Objective To measure the tapping frequency of hemiplegic unaffected forefinger and normal control's forefinger. Methods The tapping frequency of 27 left hemiplegic patients and 32 healthy controls were measured by finger oscillating frequency tester. Results The oscillation frequency of hemiplegic patients was lower than that of the healthy controls (P<0.001). Conclusion Hand function of hemiplegic patients weakened.

Laboratory teaching played the crucial part of microbiology teaching, which was benefit to improve the operational capacity, analysis and resolving ability of students. We carried out the multiplicity teaching by remodeling experiment process, designing integral test, and resolving practical issue and setting up comprehensive trail. It was proved by fact that the multiplicity teaching increased the study interesting of students, inspired their activity, initiative and creativity.

Objective To design and develop a kind of venipuncture auxiliary device to use in the absence of light condition or patients with poor vein condition, and validate its clinical effect. Methods A total of 70 patients with shock were divided into experimental group (venipuncture auxiliary device group with 37 cases) and control group (non-device group with 42 cases) by random digits table method. The one-time puncture success rate and operating time were compared between two groups. Results The one-time puncture success rate was 94.59%(35/37) in experimental group and 78.57%(33/42) in control group, and there was significant difference, χ2=4.214, P<0.05. The time of establishing a single vein passage was (73.63±29.35) s in experimental group and (107.61±45.94) s in control group, and there was significant difference, t=3.656, P<0.05. Conclusions The device is small in size, low cost, easy to carry, the screen is clear, is a rapid infusion with explore vascular equipment. It can guide nurses accurately on vascular puncture, fast, smooth and effective transfusion puncture process.

Objective To extract the color feature of tongue image.Methods The tongue image was divided into 8?8 dynamic rectangular grids. Then the color histogram of each grid was calculated. All of them composed a high-dimensional vector (we call it the original feature vector).Finally, the dimensionality of the original feature vector was reduced by using Landmark Isomap. Results Experiments on 3 594 tongue images showed that several color features of tongue image, such as the color of tongue substance, the color of tongue coat, the shades of tongue color, and so on could be extracted. Conclusion This proposed method can be used to extract the color feature of tongue image effectively.

ObjectiveTo investigate the therapeutic effects of modified constraint-induced movememt therapy(mCIMT) on upper extremity motor function of stroke patients with hemiparasis, and to compare the effects of mCIMT with those of conventional rehabilitation.MethodsThirty stroke patients with hemiparesis were divided into mCIMT group and control group (conventional rehabilitalion), 15 cases in each group. The mCIMT group received mCIMT (by shaping) in the affected extremity without restriction of movement of intact upper extremity, 6 h a day, five times a week, for two weeks while the control group was treated with traditional rehabilitation in upper-limb and hands functional exercises. Motor activity logs(MAL) score and simple test for evaluating hand function(STEF ) score were measured in two groups before treatment and 2 weeks, 1 month and 3 months after treatment.ResultsThere were improvement in MAL and STEF scores in both mCIMT group and control group 2 weeks after treatment compared with pre-treatment(P<0-01), and the scores of MAL and STEF on post-treatment 1 month and 3 months were higher than those of pre-treatment in mCIMT group (P<0-05, P<0-01), but there was no significant difference in MAL and STEF score between pre-treatment and post-treatment 1 month and 3 months in control group(P>0-05).ConclusionSignificant improvement in the affected hand function could be achieved with modified constraint-induced movement therapy in stroke patients, better than conventional rehabilitation therapy.
