Objective To determine the expressions of transcription factor activator protein-2α (AP-2α), estrogen receptor-β (ER-β) and matrixmetalloproteinase-9 (MMP-9) in lichen planus (LP) lesions and their significance. Methods Tissue samples were resected from the lesions of 30 patients with LP and normal skin of 30 human controls. An immunohistochemical method using streptavidin-peroxidase (SP) was performed to detect the expression of ER-β and MMP-9, reverse transcription-PCR and Western blot to measure the mRNA and protein expressions of AP-2α, ER-β and MMP-9 in these specimens. Results There was a significant decrease in the mRNA expressions of AP-2α (0.488 ± 0.039 vs. 1.008 ± 0.023, P < 0.01 ) and ER-β (0.365 ± 0.032 vs. 0.998 ± 0.036, P < 0.01), together with an increase in the expression of MMP-9 (1.237 ± 0.027 vs. 0.567 ± 0.015, P< 0.01) in the LP lesions compared with the control specimens; similar results were observed for the protein expressions of AP-2α, ER-β and MMP-9. In LP lesions, the expression of AP-2α was positively correlated with that of ER-β (R = 0.89, P < 0.01), but negatively correlated with that of MMP-9 (r = -0.91, P < 0.01). Conclusions The down-regulation of ER-β expression and up-regulation of MMP-9 expression may be ascribed to the abnormal regulation of upstream target genes mediated by the decreased expression of AP-2α, which may be involved in the pathogenesis of LP.

The centrosome plays a crucial role in the maintaining of cell conformation,mitosis and chromosome seg-regation.It responds to the DNA damage and keeps the genome stability via cross-talking with the intranuclear DNA damage repair system.The apoptosis of tumor cells can be induced through inhibition of the duplication of centro-some.So the inhibitors of centrosomal proteins will be a potential anti-tumor therapy.

The vascular morphological character of the microcirculation in the nail bed of the toe have been studied with the scanning electron microscope. Three types of vascular network were identified: 1) The blood vessels at the proximal two fifth of the nail bed were parallelly arranged. 2) At the middle two fifths of the nail bed, the blood vessels interwoved with each other and formed the polygonal vascular networks. 3) At the distal one fifth of the nail bed there were only a few vascular loops running in a slanting position. These loops were connected with the vascular network from the papillary layer of the skin of the toe.

Micro positron emission computed tomography (PET) is a sort of tomography technique specifically for small animal stud-ies. It can be used to observe radionuclide labeling molecules in vivo, especially for neuronal activities noninvasively, dynamically and quan-titatively at the molecular level. MicroPET can be used for early detection of atherosclerotic plaques, measurement of cerebral blood flow, judgment of the survival status in cerebral ischemia area in animal model. It is important for the control of risk factors, disease diagnosis, dis-ease staging and evaluation of curative effect.

Microglia(MG)is recognized as the main immune effector in central nervous system injury and disease.MG can regulate the tumorigenesis and development of brain metastases tumor(BMT)by different ways.Studing the roles and mechanisms of MG in BMT will provide new insights into the prevention and treatment of BMT.

Objective:To evaluate therapeutic effect and safety of rosuvastatin on patients with hyperlipidemia com‐plicated hyperuricemia .Methods :A total of 88 patients with hyperlipidemia complicated hyperuricemia ,who were hospitalized in our hospital ,were selected ,randomly and equally divided into rosuvastatin group (10 mg/d) and atorvastatin group (20 mg/d) ,both groups were treated for eight weeks .Changes of levels of blood lipids and serum uric acid (SUA) were observed and compared between two groups before and after treatment .Results:Compared with before treatment ,after eight -week treatment ,there were significant reductions in levels of blood lipids (ex‐cept high density lipoprotein cholesterol ) and SUA in both groups , P<0.01 all;compared with atorvastatin group after treatment ,there were significant reductions in levels of total cholesterol [ (4.87 ± 0.47) mmol/L vs .(4.48 ± 0.53) mmol/L] in rosuvastatin group (P=0.04) ,and there was no significant difference in SUA level between two groups , P>0.05. There were all no more serious side effects in both groups .Conclusion:While reducing blood lipid levels ,rosuvastatin can also reduce serum uric acid level in patients with hyperlipidemia ,and it possesses good safety and tolerance .

[Objective] To guide the health preservation more scientifically and effectively through discussing relationship between natural timing and spirit-regulating, and studying the influence of lifecycle and time sequence regularity on the spirit-regulating. [Methods] The relationship of body and spirit, time property of the spirit, time sequence regularity and those lifecycle were adopted to analyse the theoretical basis and specific measures on regulating spirit based on time differentiation. [Results] Body as well as the spirit would be followed by the changes of the time sequence regularity, also at different stages of human body, the spirit changed with it accordingly. [Conclusion] TCM holds that body and spirit are unified, the lifecycle and natural timing affect human body and spirit correspondingly, so if we know the relation of the spirit and time, regulate spirit by time differentiation, which must be helpful for keeping good mind, even for health and longevity.
