The remodeling and reparative process post myocardial infarction (MI) can be divided into three phases:the inflammatory phase,the proliferative phase and the stable phase.The inflammatory immune response plays an important part in the process of cardiac remodeling.First of all,the initiation of inflammatory response relies on the activation of innate immunity with a group of pro-inflammatory cytokines,chemokines and adhesion molecules.These molecules lead to the infiltration of the infarct area with neutrophils and mononuclear cells,further clearing the wound from dead cardiomyocytes and matrix debris.After resolution of inflammatory response,reparative cells and cytokines infiltrate into the heart and promote the differentiation and growth of myofibroblasts and endothelial cells,contributing to wound contraction as well as producing fiber tissue to form a scar.Moreover,overactive immune responses could accentuate infarct injury and dilative remodeling while deficiency of inflammation leads to insufficient repair,which highlights the dual function of the immune response in myocardial injury and repair post MI.Also the intense immune response along with fibrosis in non-infarct area is also closely associated with adverse remodeling.Thus,targeting specific factors in the inflammatory reaction may hold promise in patients with MI.

Objective To evaluate the influence of tracheal intubation guided with light wand on hemodynamics in patients with obstructive sleep apnea syndrome.Methods Seventy-four patients with obstructive sleep apnea syndrome were randomly divided into light wand group (n =37) and laryngoscope group (n =37).The time to successful intubation,rate of successful intubation,changes of heart rate (HR),systolic blood pressure (SBP),diastolic blood pressure (DBP) and complications were compared in two groups.Results The time to successful intubation of light wand group was significantly shorter than that of laryngoscope group,while the rate of successful intubation in light wand group was significantly higher than that in laryngoscope group (P＜0.05).The HR,SBP and DBP at T1 were significantly lower than those at T0 in two groups (P＜0.05).The HR,SBP and DBP in two groups at T2,T3 were significantly higher than those at T1 (P＜0.05),and those indexes of light wand group were significantly lower than laryngoscope group at T2 and T3 (P＜0.05).The incidence rates of complications in light wand group were significantly lower than those in laryngoscope group (P＜0.05).Conclusion With the advantage of higher success rate,shorter time to successful intubation,more stable hemodynamics and fewer complications,tracheal intubation guided with light wand is worthy of popularization and application in clinical.

Small intestinal submucosa has been applied in a variety of areas of basic and clinical study with its Characteristics of anti-infective and Low immunogenicity and so on.However,it is common to find the shrinkage and other problems in some tissue repair,and affects the functional recovery of repaired tissue to a certain extent.Thus,it is still a question to be resolved that how to avoid the shrinkage and other adverse effects after tissue repair.This paper provides a reliable basis for further correct understanding of the SIS's capacity of tissue repair by reviewing and summarying its characteristics and present situation of tissue repair,especially put forwarding the shrinkage problem.

Objective The oligomeric and polymeric proanthocyanidins in different fractions from Hippophae rhamnoides seeds were investigated. Methods The monomeric and oligomeric fractions were analyzed by HPLC/ESI-MASS detection. The polymeric proanthocyanidins were fractionated by Sephadex LH-20 column chromatography and their chemical constructures were studied by acid-catalysed degradation in the presence of benzyl mercaptan. Results Four monomers were identified as catechin, epicatechin, gallocatechin, and epigallocatechin. Eight dimers including three dimeric procyanidins and one dimeric prodelphinidin, and four mixed dimers were detected and their structures were partly elucidated by the detection of the pseudomolecular ion and main ion fragmentations. The results also showed that polymers to be highly heterogenous with catechin, epicatechin, gallocatechin, and epigallocatechin all being components of both the extension and the terminal units. The extension units were mainly gallocatechin, whereas the terminal units were mainly gallocatechin and epigallocatechin for all fractions. The proanthocyanidins with a mean degree of polymerization (mDP) of 9.1, 13.2 and 17.0 represented the three major polymeric fractions. Conclusion Proanthocyanidins of H. rhamnoides seeds, predominantly being of prodelphinidin-type, are remarkably different from that of grape seeds.

It provides a new approach to treat myelodysplastic syndromes when decitabine comes out.In order to improve the understanding of the role of decitabine and to provide a reference for the clinical treatment of middle-risk and high-risk myelodysplastic syndromes,this article mianly summarized drug combination,prognostic molecular markers,and reviewed the mechanism of action,main medication regimen in recent 5 years for the treatment of middle-risk and high-risk myelodysplastic syndromes with decitabine.

Objective To explore the impact of maximal movement on the stabilization of the four corner arthrodesis.Methods Flexion,extension,ulnar deviation and radial deviation movements were simulated on the wrists of 21 fresh cadaver fore-arm specimens.Maximal movements were performed in each of the four directions. Firstly,anteroposterior view and lateral view photos were taken before and after movement in each direction.Sec- ondly,capito-lunate angle,radio-lunate angle,captio-lunate posteroantefior angle,the height and width of the syzygium were measured before and after movement in each direction.The wrist before each kind of movement was used as the control for itself after the movement in the test.Results Compared with the control data,the differ- ences in capito-lunate angle,radio-lunate angle and the height of the syzygium were statistical significant before and after movement in the direction of flexion 40?and extension 30?(P＜0.05).Moreover,the differences in the captio-lunate posteroanterior angle and the width of the syzygium were also statistical significant before and after movement in radial deviation 15?and ulnar deviation 20?(P＜0.01).Maximal movements at other positions had little impact on the stability of the arthrodesis.Conclusion It is safe to perform high intensity movements to the four-comer syzygium when the range of motion is not beyond flexion 40?,extension 30?,ulnar deviation 20?and radial deviation 15?.Cireumduction should be avoided.

Nowadays more and more attention has been paid to the problems about housing and health in China. Some investigations showed that people spent almost fourteen hours in their homes every day so the houses become the major places of daily activities. It is very important to solve the problems of what is the relation between the housing and health and how the housing influences the health of the people living in it. In the present paper the author summarized the overseas and domestic researches on the housing and health and pointed out that the research on housing and health in China is just in the preliminary phase.

Objective To study the effect of Naotongliting capsule (NLC) on hemorheology and platelet aggregation in blood stasis rats. Method The rat model of blood stasis was established with adrenaline subcutaneous injection in combination with ice-water socking. Aspirin and Yangjiao capsule were selected as contrast medicine to observe the effect of NLC on whole blood viscosity, plasma viscosity, haematocrit, fibrin and platelet aggregation in blood stasis rats. Result NLC could reduce hemorheology and platelet aggregation in blood stasis rats. Conclusion NLC is helpful to adjust hemorheology and plateiet aggregation in blood stasis rats, indicating its good effect of activating blood circulation to remove blood stasis.
