Objective] Discuss the“five seasonal organs”theory of The Inner Canon of Huangdi, especially the seasonal issues of the spleen and preliminarily speculate the formation period. [Methods]By means of literature and historiography methods, information before The Inner Canon of Huangdi would be gathered, especially“The Book of Rites·on Order”,“Guanzi·Seasons”,“Annals by Lv·Twelve Ji”and so on. On this basis, we can discuss the different perspectives of “five seasonal organs”theory and the seasonal issues of the spleen of The Inner Canon of Huangdi, and preliminarily speculate the theory’s origin, evolution, and formation. [Results]“Six periods connected to six internal organs”theory is more concerned with the meaning of anatomy, although it is early view of the“seasonal organs”theory, but six or twelve has its specific cultural origins;“Eight wind connected to eight internal organs”theory is affected by Zhou Yi;“four periods connected to four internal organs”theory couldn’t explain attribution of the“soil”and its role, it belongs to the early stages of Qi argumentation of the“seasonal organs”theory after the introduction of the Five Elements Theory;“five periods connected to five internal organs”theory reflected the tight integration with the theory of five elements and balanced attachment features; the theory which has the most theoretical and clinical meaning is“four periods connected to five internal organs”theory. [Conclusion] The different perspectives of“five seasonal organs”theory and the seasonal issues of the spleen of The Inner Canon of Huangdi are results of a number of philosophical thoughts absorbed by different doctors, but through analysis of the relevant literature, the core ideas can be briefly summarized, it can be generalized that the spleen is located in the center, connected at any time, behalf of governance after each season ’s eighteen days.

Caveolae are cholesterol-rich pits on the surface of cell membrane,and participate in various physiological processes.Caveolin-1 is an important membrane protein constituting caveolae.It exerts biological effects through binding a variety of signaling proteins.In the pathophysiological processes of cerebrovascular disease,caveolin-1 participates in maintaining the integrity of blood-brain barrier and stability of atherosclerotic plaques,and has regulating the release of inflammatory mediators and neuroprotection.This article reviews the associated advances in research on the correlation between caveolin-1 and cerebrovascular disease in order to provide a new idea for clinical therapy.

Eisenmenger syndrome (ES) was considered as a surgical contraindication in the past time. Only a few patients got lung transplantations or heart-lung transplantations due to lack of donors. Most of the patients had to choose conservative treatment to prolong their survival time. Recently, some clinical trials indicated targeted therapies in pulmonary arterial hypertension (PAH) were effective for the treatment of ES. This article reviewed the recent advances in this area.

To evaluate security of influenza virus vaccines by analysis of adverse reaction to influenza virus vaccine,especially the relationship between Guillain Barr? syndrome and influenza vaccines.

We investigated whether platelet-activating factor (PAF) mediates endotoxin-induced changes of lipoperoxidation, lysosomal enzyme release and increased extravascular lung water content in dogs using a specific PAF receptor antagonist, SRI 63-441. Endotoxin infusion caused an increase in serum malonyldialdehyde (MDA) from baseline (100%) to 130.04?14.00% and 169.16?32.49% and ?-glucuronidase (?-g) activity to 191.05?86.71% and 242.54?49.09% at 3 and 6h, respectively. The bronchoalveolar lavage fluid (BALF) ?-g activity, lung MDA and extravascular lung water also significantly increased (P

Perception, affection and consciousness are basic psychological functions of human being. Affection is the subjective reflection of different kinds of objects. The foundation of human being's thinking is constituted by the three basic functions. Affective computing is an effective tool of revealing the affectiveness of human being in order to understand the world. Our research of affective computing focused on the relation, the generation and the influent factors among different affections. In this paper, the affective mechanism, the basic theory of affective computing, is studied, the method of acquiring and recognition of affective information is discussed, and the application of affective computing is summarized as well, in order to attract more researchers into this working area.

Objective:To evaluate the effects of several kinds of surface treatment methods on the bond strength of zirconia prosthesis,and to provide references for improving the bond strength of zirconia prosthesis.Methods:Sixty zirconia blocks(10 mm×10 mm×2 mm) were divided into 6 groups according to the surface treatment methods:sandblasting,silica coating,Z-PRIME Plus,sandblasting+Z-PRIME Plus,sandblasting+silica coating,and silica coating+Z-PRIME Plus groups.The zirconia-resin specimens were fabricated using ScotchbondTM Universal;shear bond test was performed to detect the shear bond strength after treated with water storage(37℃) for 24 h by universal mechanical testing mechine;the fracture types were observed by stereoscopic microscope.One fracture specimen was randomly chosen from each group,and the morphology of the specimen was examined under scanning electron microscope.Results:The shear bond strength of the specimen in Z-PRIME Plus group was higher than those in the other groups(P<0.05).The adhesive failure was predominantly observed in sandblasting,silica coating,sandblasting+silica coating and silica coating+Z-PRIME Plus groups.There were 4 cases of mixed failure in Z-PRIME Plus group and there were 8 cases of mixed failure in sandblasting+Z-PRIME group.No cohesive failure was observed in all the groups.The scanning electron microscope results showed that the fracture surface occurred on the resin-zirconia interface of the specimens in sandblasting group,Z-PRIME Plus group,and sandblasting+Z-PRIME Plus group.The silica-zirconia fracture of specimens occurred in silica coating group and silica coating+Z-PRIME Plus group.The silica-resin interface fracture of specimens partially occurred in sandblasting+silica coating group.Conclusion:The application of Z-PRIME Plus can significantly improve the bond strength between zirconia and resin.

Objective The aim of this study was to investigate the accuracy and reliability of linear measurements using cone beam computed tomography(CBCT) system and to provide theoretical application of CBCT in oral implantation. Methods Ten experimental models of different toothless mandibles mixed with 10% of barium sulfate were used in this study. All these mandible models were marked with gutta-percha markers to standardize the plane of the transverse cross-sections and path of measurements. The mandible models were imaged using Mayer SS-X9010D CBCT device. Measurements were taken with DCT Viewer software and compared with measurements recorded directly in the mandible models using vernier caliper. A paired sample t-test was performed to compare difference between CBCT measurement and vernier caliper measurement. Less than 0.05 were considered statistically significant. Results The differences of vertical lines between CBCT and vernier caliper were (-0.089 5±0.220 0) mm in anterior teeth area and (-0.083 0±0.190 0) mm in posterior teeth area. The differences of vertical lines between CBCT and vernier caliper were (-0.052 0 ± 0.140 0) mm in anterior teeth area and (-0.084 7 ± 0.320 0) mm in posterior teeth area. The corresponding t values were-1.784,-1.981,-1.621 and-1.684, respectively. All the P values were greater than 0.05. There was no significant difference between CBCT measurement and vernier caliper measurement. Conclusions CBCT is auseful tool to provide good accuracy and precision of linear measurement in dental implants.

Objectives To explore the effect of mibefradil, a kind of novel calcium channel antagonists, on proliferation of human pulmonary artery smooth muscle cells (HPASMCs) induced by platelet-derived growth factor (PDGF). MethodsHPASMCs were culturedin vitro, and randomly divided into control group, PDGF group, Mib group, and PDGF+Mib group. The PDGF group was stimulated by 25 ng/ml of PDGF. Mib group was intervented by 10 μmol/L of Mib. PDGF+Mib group was treated by PDGF and Mib. The reproduction rate in 48 hours and 72 hours were detected by MMT. Cell cycle was detected by lfow cytometry. The expression of proliferating cell nuclear antigen (PCNA) was observed by immunolfuorescence staining (IFS).ResultsThere were statistical differences among four groups in both 48 hours and 72 hours (P all??0.05). There were statistically differences of G0/G1 phase and S phase among four groups (P?
