This study was aimed to reveal the roles of biological factors T3, T4 and TSH in the pathogenesis of liver-qi invasion syndrome and liver-qi depression syndrome of premenstrual syndrome (PMS) in the body. Thus, we may expound the connotation of conceptpotential stagnation ofqi and blood. Female workers of Jinan and Qingdao were selected as target groups by epidemiological cross-sectional survey. And specially trained investigators were responsible for screening patients referred to criterion on the international diagnostic standards and syndrome diagnosis of PMS. Patients' blood was taken as samples during the follicular phase (6 to 14 days), luteal phase (15 to 23 days), premenstrual phase (24 to 28 days) and the menstrual phase (1 to 5 days), respectively. Blood samples were disposed according to requirements of radioimmunoassay. Single factor analysis of variance was used in the comparison with the level of T3, T4 and TSH in menstrual blood for different time intervals of the case group and the normal group by SPSS 10.0 statistical software. The results showed that T3 levels of patients with either syndrome were significantly reduced during the premenstrual phase and the menstrual phase (P < 0.05). There were no significant changes on the level of serum T4 and TSH before and after the occurrence of the disease. Both of them were significantly increased during each phase of the menstrual cycle. It was concluded that changes of T3, T4 and TSH were one of the mechanisms in disease with liver-qi invasion syndrome and liver-qi depression syndrome. The micro change was the essence ofpotential stagnation of qi and blood, which was the body condition of this disease.

Objective Aimed at the problem that there is no curative effect standard of liver-qi invasion of premenstrual syndrome (PMS), to construct the reference standard of curative effect evaluation for the liver-qi invasion of PMS. Method Curative effect evaluation research of Jingqianping granule was designed by the principle of random, double blind, contrast and multicentre. Three hundred and fifty-six patients with liver-qi invasion of PMS were divided into two groups randomly, one was Jingqianping granule, the other was placebo. Patients were given Jingqianping granule and placebo respectively for two menstrual cycles and followed–up for three menstrual cycles. The reference standard of curative effect evaluation for the liver-qi invasion of PMS was constructed with daily rating of severity of problems form (DRSP). Result Jingqianping granule and placebo have therapeutic effect on the patients with liver-qi invasion of PMS, and Jingqianping granule was better than placebo. DRSP can be used as indexes of curative effect evaluation. Conclusion The initial establishment of the curative effect evaluation criterion of PMS liver-qi invasion provides the important foundation for profession criterion’s establishment.

Calcium/calmodulin-dependent protein kinaseⅡ (CaMKⅡ) has multiple functions, which made it play a central role in cardiovascular disease. Especially it activates numerous downstream targets in various signaling pathways that promotes vascular disease, heart failure, myocardial hypertrophy and arrhythmias. CaMKⅡcan impact calcium balance and increase calcium leak in myocardial cell via phosphorylating L type calcium channel, Ryanodine receptor (RyR 2) and phos?pholamban (PLN), and regulate ATP sensitive potassium current (IKATP) and late sodium current by affecting sodium channels and potassium channels. In addition, It can directly regulate transcription via activating the silk crack the original activated protein kinases (MAPKs) and acetylation enzyme (HDAC). These mechanisms have important roles in myocardial hypertro?phy, heart failure and arrhythmia. So we focus to demonstrating the structure and action mechanism of CaMKⅡto improve a new therapy of cardiovascular disease.

Hidden-pathogen theory is always a leading theory of febrile disease etiology from the proposal until the Ming Dynasty and it plays a critical guiding role on development and maturity of febrile disease theory. However, along with the change of times and drift of disease spectrum, this theory is facing unprecedented challenges. The gradually in-creased clinical experiences and facts have been difficult to be explained and induced using the already existed hidden-pathogen theory. Since hidden-pathogen theory has its own theoretical status and value, which cannot be lightly given up, the question of how to develop this theory in order to better reveal the pathogenesis in the guidance of diagnosis and treatment has become the focus of attention. This paper tried to proposeemotional hidden-pathogenas an example to provide a possible paradigm to develop hidden-pathogen theory and systematically expound main ideas and reasoning processes of emotional hidden-pathogen doctrine and to explore its theoretical significance and application value.

BACKGROUND: Previous studies showed that donor systemic injection of B7/CD28 costimulatory blocker cytotoxic T lymphocyte associated antigen 4 immunoglobulin (CTLA-4Ig) needed in T cell activation can markedly prolong the survival time of rat renal allografts, which, however, has limitations, such as high dose, extensive influence, poor specificity, systemic adverse reactions.OBJECTIVE: In order to improve the targeting of CTLA-4Ig, we modified the dendritic cells of donors and recipients in vitro with CTLA- 4Ig and observed the influence of two kinds of dendritic cells applied alone or together on the survival of renal allografis in rats.DESIGN, TIME AND SETTING: The randomized controlled animal experiment was performed between April 2003 and July 2004 at Laboratory of Department of Urinary Surgery, Xinqiao Hospital, the Third Military Medical University, Chongqing, China.MATERIALS: Kidney donor: inbred Brown-Norway rats, kidney recipient: inbred Lewis rats, unrelated lymphocyte donor: Wistar rats.METHODS: Bone marrow derived dendritic cells of Lewis and Brown Norway rats were modified with CTLA- 4Ig gene recombinant adenovirus in vitro. Animal models of kidney transplantation were built with Brown Norway rats as donors while Lewis rats as recipients. The modified dendritic cells were injected into Lewis rats through femoral vein 24 hours before kidney transplantation alone (group 1 (n=8), donor dendritic cells; group 2 (n=8), recipient dendritic cells) and in combination (group 3 (n=8), donor and recipient dendritic cells). While the recipients without injection were used as control (group 4 (n=6)).MAIN OUTCOME MEASURES: Survival time of renal allografts; the reaction degrees of splenocytes to donor and unrelated antigen determined by MTT method on day 20 postoperation.RESULTS: Survival time of renal allografts in group 2 was not prolonged compared with group 4 while the survival time was markedly prolonged in group 3 (P < 0.01). The response of rat splenocytes to donor antigen in group 1 and group 3 was obviously lower than that in group 4 (P < 0.01), while the response to unrelated antigen was similar to group 4.CONCLUSION: Donor dendritic cells modified with CTLA- 4Ig can significantly prolonged survival time of rat renal allografts and the administration of both donor and recipient dendritic cells modified with CTLA- 4Ig can induce a longer survival time of renal allografts. Recipient dendritic cells cannot prolong the survival time of renal allografts.

Objective To summarize the subtle anatomical structures of the normal nasal bone in mul-ti-slice spiral CT (MSCT) image through the observation of the three-dimensional images. Methods One hundred and twenty volunteers who had no nasal trauma and disease history were collected. The nasal was scanned using MSCT. Raw data was reconstructed into bone window images (slice thickness 0.6 mm, slice interval 0.5 mm), and then the images were imported into Syngo Imaging XS software to recon-struct three-dimensional images and to summarize the nasal bone ’s subtle anatomical structures. Results The subtle anatomy of normal nasal bone generally included four seams, two holes and one edge. The four seams were left and right nasal-maxillary suture, nasal-frontal seam, and internasal suture. The two holes were left and right nasal aperture. The edge of the nasal was the lower edge of the nasal bone. In addition, there was suture bone in internasal suture in some normal nose. The nasal aperture mostly was hole-like, but some nasal apertures were line shape. The nasal edge can be divided into flat type, wave-shaped type, inverted spike type, hook-shaped type and others. Conclusion The anatomy diversity and individual differences in nasal bone are large. MSCT and three-dimensional image reconstruction techniques, combined with the history of trauma could distinguish between the normal anatomy and fractures.

This study was aimed to solve the problem of overall syndrome differentiation information collection on patient’s main complain of traditional Chinese medicine (TCM) four diagnostic methods, in order to make syndrome differentiation standard of premenstrual syndrome (PMS) with liver-qi invasion pattern. The method of cluster sampling was applied in the investigation. The appropriate structural equation modeling (SEM) was established according to multi-dimension indexes of case features and TCM theories. The results of the “information acquisition form for doctor” structural equation showed that emotion dimension, body-symptom dimension, organism condition dimension load coefficients were 0.715, 0.574 and 0.904, respectively. The results of the “information acquisition form for patient” structural equation showed that emotion dimension, body-symptom dimension, organism condition dimension load coefficients were 0.705, 0.945 and 0.848, respectively. There were strong relativities among all dimensions. Combined with TCM theories, the main symptom of identified PMS with liver-qi invasion pattern was “irritable and angry”. And the secondary symptoms contained headache, breast tenderness, distention and pain of lower abdomen and stomach. The combining symptoms were insomnia, dreaminess, swelling of extremities, fatigue, inefficiency for work and housework, hard to focus the attention. It was concluded that the combination of information acquisition method from both the doctor and patient established a relative comprehensive information acquisition system. It established the syndrome differentiation standard of PMS with liver-qi invasion pattern for the first time based on epidemiologic investigation. It provided important reference for the study of PMS subtype.
