Objective:To assess the effect of localization of cerebral stroke on cardiac damages and cardiac autonomic nervous activity.Methods:ECG,plasma CK-MB level and heart rate variability(HRV) recordings were measured and analysed among 389 patients with hemispheric cerebral stroke in the acute phase and among 206 control subjects.Results:Supraventricular arrhythmias and prolonged QTc were significantly increased in groups of right insular infarction,fight putamental and frontoparietotemporal hemorrhage as compared with groups of stroke in other regions.A significantly increased rates of ST segment abnormalities were found in groups of left insular infarction,left putamental and frontoparietotemporal hemorrhage as compared with groups of stroke in other regions.Plasma CK-MB level increase was only found in insular infarction,and similarity was seen between the right and left.The measured components of HRV,ie,HF,RMSSD,and PNN50 were significantly lower,and LF/HF were significantly higher in groups of right insular infarction,right putamental and frontoparietotemporal hemorrhage in acute phase compared with groups of stroke in other regions and control group.Conclusion:The effects of hemispheric stroke on heart function and cardiac autonomic nervous activity are mainly correlated with destruction of insular or regions adjacent to the insular.

Acute ischemic stroke is characterized by high morbidity,high mortality and high disability.It seriously affects the health of middle-aged and elderly persons.Searching for the relevant factors that influence the neurological outcome in patients with acute ischemic stroke and interfering with them are one of the research hotspots in this field.Studies in recent years have shown that matrix metalloproteinase-9,neuronspecific enolase,S-100B protein,brain natriuretic peptide,copeptin,blood lipids,blood glucose and other hematological parameters may be associated with the neurological outcome in patients with acute ischemic stroke.

Owing to the advanced age,limb hemiplegia,dehydration,and vessel wall injury,stroke may be easy to cause venous thromboembolism (VTE).VTE mainly include deep vein thrombosis (DVT) and pulmonary embolism (PE).DVT refers to abnormal blood clotting in the veins and impedes venous return.The dislodgement of emboli from the vessel wall can form a thrombotic embolism,and cause PE,myocardial infarction,and stroke; it can not only prolong hospitalization,but also increase the mortality.This article reviews the incidence,risk factors,treatment,and prevention of DVT after a stroke.

Myelin-associated inhibitory factor is a major obstacle for axonal regeneration in the central nervous system, and Nogo-A is an important inhibiting factor synthesized by oligoden-drocytes. Toe expression levels of Nogo-A changed significantly in a model of ischemic cere-brovascular disease; the therapeutic measures aiming at Nogo-A and its downstream pathway can effectively enhance axonal regeneration, improve the plasticity of neural structure, and promote functional recovery. This provides a reliable theoretical basis for the development of therapeutic mode in human cerebrovascular diseases.

Brain edema is a common pathophysiological response in clinical practice.Now it is considered that aquaporin-4 (AQP4) participates in the formation and regression of brain edema,the latest research results of its structure, distribution, expression and regulation have indicated that AQP4 plays all important role in brain edema.

OBJECTIVE: The goal of this study was to study the mechanism of substance P (SP)-mediated the neural control of mast cell (MC) degranulation. METHOD: Bone marrow mast cells from mice were cultured with stem cell factor (SCF), IL-3 and IL-4 (group A) and SCF, IL-3 (group B) for four weeks. Then the cells were harvested and reserved for studies. Western Blot hybridization technique was used to detect the expression of FcεR I α and NK-1R on MCs from the two groups. Then such cells were activated with SP (0, 0. 01, 0. 10, 1. 00, 10. 00 µg/ml, respectively) for 30 min. The histamine released into the supernatant and stored in the protoplasm was quantified by enzyme linked immunosorbent assay (ELISA). And the percentage of histamine release was calculated as a percent of total histamine content. RESULT: The expressions of FcεR I α and NK-1R on these mast cells in group A were statistically higher than in group B (P<0. 05). The MCs from two groups can be actived when stimulated by SP, but the level of MC degranulation in group A was higher than group B (P<0. 05). CONCLUSION Neuropeptide may stimulate MC degranulation through immunological and non-immunological pathways. In summary, the current study provides us with better understanding of the mechanism of neuropeptide-controlled MC deranulation, and this should be helpful for the further research involved in the mechanism and treatmemt of airway hyper-reactivity.

The post-stroke depression refers to a affective disorders within 2 to 3 years after stroke in patients with stroke.Its main features are depressed mood,decreased interest,irritability,pessimism,and slow thinking,etc.Usually the symptoms will last for more than 2 weeks.It is one of the most common complications of stroke and may seriously affect the rehabilitation and quality of life of patients.Some patients even have suicidal tendency.Early intervention is very important for late neurological recovery in patients with stroke.It can not only improve cognitive function,but also reduce the morbidity and mortality.This article reviews the treatment of post-stroke depression.

In recent years , the increasing number of private medical institutions in China has not led to the re-sponding increase in medical services , capital asset scales .The competitive situation between public and private medical institutions has not yet been formed .This paper discusses the difficulties that Chinese private medical institu-tions have encountered in overseas capital inflow , in order to foster local private medical Institutions , as well as the development of private non-profit hospitals .Based on a systematic analysis of the key points in policy , suggestions were proposed in regarding with enhancement of top-level design of the policies , encouragement of the development of off-shore or on-shore small-scale private medical institutions , as well as facilitation of the productive factors flow in medical institutions'operation.The suggestions on the policies are to be referenced in decision making for a healthy development of Chinese private medical institutions .

With Jianyu (LI 15), Jianliao (TE 14) and Jianzhen (SI 9) for instance, the three acupoints used to treat shoulder bi syndrome by needle knife, and through traceability and researching constant structure, the acupoint position, insertion trace, manipulation and clinical significance of needle knife medicine were discussed. Accurate position is one of the characteristics of acupoints selection of needle knife medicine. As for the acupoints selection method, the mean of body surface localization is always used. The phanerous or palpable bone processes, muscles and tendons are taken as positioning marks; pressing areas where appear sour, numb, or distensible and other sensations is considered as the principle of press positioning. So acupoints position method is the combination of observation and palpation. Different insertion methods can effectively relieve the accretive bursae synovialis, tendon, joint capsule and the compressed nerve, so that shoulder bi syndrome is relieved.

Objective To study the effects of NEP1-40 on axon regeneration, motor function recovery of affected limbs and RhoA signal pathway in cerebral ischemia-reperfusion rats for exploring the possible mechanisms. Methods A total of 60 adult male Sprague-Dawley (SD) rats were equally divided into sham operation group (sham group), cerebral ischemia-reperfusion control group (control group), intra-lateral ventricle injection of PBS group (PBS group), and intra-lateral ventricle injection of NEP1-40 group (NEP1-40 group). The middle cerebral artery ischemia-reperfusion model (MCAI/R) was established by nylon monofilament occlusion method in rats. The changes in growth associated protein-43 (GAP-43) and RhoA expressions were determined by Western blotting technique. The motor function of affected limbs was tested by the "staircase test" of Montoya’s design. Results ① The expression of GAP-43 in NEP1-40 group was higher than that in the control and the PBS groups at 7 d and 14 d after MCAI/R, peaking at 7 d; ② The expression of RhoA in NEP1-40 group was significantly lower than that in the control and the PBS groups at each time point; ③ The results of "staircase test" in NEP1-40 group were much higher than those in the control group and the PBS groups at each time point after MCAI/R. Conclusion NEP1-40 can improve axon regeneration in cerebral ischemia-reperfusion rats and promote the recovery of motor function. The mechanism may be associated with the inhibition of RhoA signal pathway.
