Hypoxic-ischemic brain damage (HIBD) is referred to a common type of cerebral damage, which is caused by injury, leading to shallow bleeding in the cortex with intact cerebral pia mater. In recent years, studies show that a various kinds of immune cells and immune cellular factors are involved in the occurrence of HIBD. CC chemokine receptor 2 (CCR2) is a representative of CC chemokine receptor, and is widely distributed in cerebral neuron, astrocyte, and microglial cells, and is the main chemo-tactic factor receptor in brain tissue. CC chemokine ligand 2 (CCL2) is a kind of basophilic protein and the ligand of CCR2, and plays an important role in inflammation. In order to provide evidence for correlational studies in HIBD, this review will introduce the biological characteristics of CCR2 and CCL2, and illustrate the relationship between the immunoreactivity and HIBD.

Objective:
To analyze the relationship between thrombin activatable fibrinolysis inhibitor ( TAFI ) and coronary heart disease ( CHD ), and to provide evidence for the prevention of CHD.
Methods:
The patients with CHD in Fushun Central Hospital in Liaoning Province were selected as the case group, the patients without CHD in the same hospital and period were selected as the control group. The demographic information and clinical examination results ( serum TAFI, lipid, glucose, etc. ) were collected to analyze the association between TAFI and CHD by logistic regression models.The multivariate logistic regression analysis was used to explore the relationship between TAFI and CHD.
Results:
There were 222 cases, including 100 cases of stable angina, 44 cases of unstable angina and 78 cases of acute myocardial infarction, and 222 controls. The median ages of cases and controls were 62 and 57 years old. The results of multivariate logistic regression analysis showed that serum TAFI>22.88 μg/mL ( P75 of controls ) was associated with the risk of CHD ( OR=1.619, 95%CI: 1.011-2.593 ), unstable angina ( OR=2.917, 95%CI: 1.433-5.939 ) and acute myocardial infarction ( OR=2.626, 95%CI: 1.007-6.847 ).
Conclusion
The high level of TAFI is related to CHD, unstable angina and acute myocardial infarction.

Cyclin-dependent kinase 5 (CDK5) is a member of cyclin-dependent kinase family, which does not directly regulate cell cycle. Through phosphorylation of target protein, CDK5 plays an irreplaceable role in the development, reparation and degeneration of neurons. Brain injury refers to the organic injury of brain tissue caused by external force hit on the head. Owing to the stress and repair system activated by our body itself after injury, various proteins and enzymes of the brain tissues are changed quantitatively, which can be used as indicators for estimating the time of injury. This review summarizes the progress on the distribution, the activity mechanism and the physiological effects of CDK5 after brain injury and its corresponding potential served as a marker for brain injury determination.

In the development of diabetic nephropathy (DN), reactive oxygen specie (ROS) over much in vivo leads to oxidative stress(OS)-related renal injuries, which are characterized by the structural and functional changes in glomerular and renal tubular cells in morphology. The regulative approaches of OS involve the several signaling pathways, in which, both p38 mitogen-activated protein kinase (MAPK) signaling pathway and adenosine monophosphate-activated protein kinase (AMPK) signaling pathway play the important roles as the target of anti-oxidants. The interventional actions of Chinese herbal compound prescriptions and the extracts of single Chinese herbal medicine (CHM) on OS in the kidney in DN include regulating the balance between ROS and antioxidants, reducing the production of AGEs, inhibiting the expression of growth factors and intervening the activity of signaling pathways.

Objective To investigate the vitamin D (VD) level and determinants among young children aged 6 to 23 months in 4 poverty-stricken ethnic minority areas of Yunnan Province. Methods Multistage stratified cluster sampling method was used. 1 255 young children aged 6-23 months from 3 to 4 towns of Jianchuan County, Yiliang County, Mojiang County and Lushui County. Questionnaires on caregivers, physical and serum 25(OH)D measure were achieved. VD level and influencing factors were described and analyzed. Results Overall VD level was 20.6(16.3,25.4) ng/ml. The proportion of VD deficiency, VD insufficiency and VD sufficiency were 7.1%, 39.2% and 53.7% respectively. The risk of VD insufficiency elevated with children’age increasing or no VD supplement (P<0.05). Hani minority can decrease the risk of VD deficiency and insufficiency (all P<0.05). Thus, the risk of VD deficiency and insufficiency in children of female, Lisu or Bai minority, or in children who had no nutritional package supplement would increase (all P<0.05). Conclusions The VD level of children aged 6-23 months in poverty-stricken ethnic minority areas of Yunnan Province was low. VD insufficiency was dominating. The intervention of VD deficiency and insufficiency may focus on the children of female, Lisu minority, Bai minority or older than 18 months. This study highlight that enhancing caregivers’ knowledge of VD nutrition, adding VD and nutritional package supplement actively are beneficial to improve VD nutrition of young children in minority poverty areas of Yunnan.
