Migraine is the most common primary headache clinically, with high disability rate and heavy burden. Functional MRI (fMRI) plays a significant role in the study of migraine. This article reviews the main advances of migraine without aura (MwoA) based on resting-state fMRI in recent years, including the exploration of the mechanism of fMRI in the occurrence and development of MwoA in terms of regional functional activities and functional network connections, as well as the research progress of the potential clinical application of fMRI in aiding diagnosis and assessing treatment effect for MwoA. At last, this article summarizes the current distresses and prospects of fMRI research on MwoA.
Objective To summarize the research progress of postmenopausal breast cancer and estrogen metabolites, which is aimed at providing the basis for early diagnosis and early treatment of postmenopausal breast cancer, at the same time, providing beneficial information for the future study. Methods In recent years, the literatures about postmenopausal breast cancer and estrogen metabolites were reviewed from the databases of WanFang, VIP, CNKI, PubMed, and so on, to make an review. Results Estrogen metabolites had a dual role for postmenopausal breast cancer, such as 2-hydroxyestrone (2-OHE1), 2-methoxyestrone1 (2-MeOE1), and 4-methoxyestrone1 (4-MeOE1) played a protective role for postmenopausal breast cancer, but 4-hydroxyestrone (4-OHE1) and 16α-hydroxyestrone (16α-OHE1) played a carcinogenic role for postmenopausal breast cancer, so it needed to be further studied. Conclusions Estrogen metabolites may be a reliable predictor for the risk of postmenopausal breast cancer, it is not only to provide clues for the mechanism of postmenopausal breast cancer, but also provide new train of thought for early diagnosis and treatment of postmenopausal breast cancer.
Objective To summarize the advancement of immune tolerance in pancreas transplantation.Methods Relevant literatures about immune tolerance in pancreas transplantation, which were published recently domestic and abroad were collected and reviewed. Results The main methods to induce immune tolerance are peripheral tolerance and central tolerance. The induction of chimerism by infusion of donor-specific bone marrow cells is the research hot spot recently. Conclusion The infusion of donor-specific bone marrow cells in combination with one or more peripheral tolerance maybe can induce immune tolerance successfully. However, it should be researched further.
ObjectiveTo unscramble personal data and its tags and structures of Database from Colorectal Cancer (DACCA) in West China Hospital.MethodThe way of words for description was used.ResultsThe definition and setting of 23 items with 18 categories for the personal data from DACCA in West China Hospital was performed. The relevant data label of each item and the structured way needed at the big data application stage were elaborated and the corrective precautions of classification items were described. The three classification items involved privacy attention were described in detailed.ConclusionsBased on description about personal data from DACCA in West China Hospital, it is provided a clinical standard and guide for analyzing of DACCA in future. It also could provide enough experience for construction of colorectal cancer database by staff from same occupation.
【摘要】 目的 观察人类免疫缺陷病毒（HIV）感染后对人体各个系统的影响，为其诊断和治疗提供经验。 方法 回顾性分析2005年1月—2010年6月于华西医院确诊为HIV感染13例患者的临床表现和相关实验室指标。 结果 13例HIV感染患者均合并其他感染，以结核病最为常见；除有T淋巴细胞异常外，多数患者可合并出现血液学异常，包括贫血、白细胞和血小板降低；生化异常，包括球蛋白升高、白蛋白降低；HIV感染患者可合并出现风湿病症状和免疫学异常。 结论 HIV感染患者临床表现复杂多样，可合并出现多种感染和风湿病症状，血液学及免疫学异常也比较常见。【Abstract】 Objective To observe the impact of human immunodeficiency virus (HIV) on each system of human body after its infection, in order to provide experiences for diagnosis and treatment of this disease. Methods The clinical manifestations and related laboratory results of 13 inpatients treated in West China Hospital of Sichuan University from January 2005 to June 2010 were reviewed retrospectively. Results The incidence of infection in these patients was 100% with tuberculosis as the most common infection. Apart from the abnormality of T lymphocytes, most patients had a change of hematology and biochemistry, including anemia, depression of leucocytes and platelets, hyperglobulinemia and hypoproteinemia; HIV-infected patients may also presented with rheumatic manifestations or abnormality in the immune system. Conclusion The clinical manifestations of patients with AIDS are complicated. Many kinds of infections and rheumatic manifestations may merge and the change in hematology and immunology is common.

Objective To explore the inhibitory mechanism of Imatinib mesylate on pulmonary fibrosis induced by bleomycin inmice. Methods A total of 120 C57BL/6 mice were randomly divided into four groups, ie. a control group, a model group, a dexamethasone group, and an Imatinib group. The model of pulmonary fibrosis was established by a single intratracheal instillation of bleomycin in the rats. Then dexamethasone or Imatinib were given intraperitoneally respectively. On day 7, 14, 21 after the treatment, 10 mice of each group were sacrificed respectively. The expressions of TGF-β1 and α-SMA in lung tissue were analyzed by immunohistochemistry. The mRNA expression of TGF-β1 was measured by RT-PCR. Results The expressions of TGF-β1 and α-SMA in lung tissue at each time point were significantly increased in the model group compared with the control group. And the expressions were obviously decreased in the dexamethasone group and the Imatinib group compared with the model group, with no significant differences between the two treatment groups. The expression of TGF-β1 was positively correlated with the α-SMA expression ( r= 0. 251, P lt;0. 05) . Conclusion The inhibitory effect of Imatinib on pulmonary fibrosis may be related to the inhibition of TGF-β1 and α-SMA expressions.
Objective To explore the whole constructive conception and organization structure strategy of multi-disciplinary team (MDT) for colorectal cancer (CRC). Methods Combined the characteristics of large public hospital, with recognized treatment pathway in MDT for CRC and the way of medical project construction, MDT for CRC project team summarized a system of MDT for CRC of West China Hospital (MDT-CRC-WCH) by own characteristics and subject feature. Results MDT for CRC summarized the 5 basic characteristics about profession, classification, interaction, optimization and fast. The project has the core competencies: system new operation types for colorectal cancer and volunteer culture. By the matrix organization structure, MDT set the main departments: database team, follow-up team, nursing team and public team. Conclusion With effective MDT whole construction and suitable organization structure, MDT will develop in long time.
Objective The article explained how to build the data system and its running strategy in the mode of multi-disciplinary team （MDT） for colorectal carcinoma. Methods It illuminated the cause of the data system building, also described the essential composition of the data system and how to support the running of the data system, and it discussed the value feedback of the data system, lastly the author proposed the prospect of the data system building. Results The data system could work normally through consultation of doctors, follow-up, clinical support and appropriate implement of construction of information flow-sheet in colorectal carcinoma MDT mode. Conclusion As the foundation of colorectal carcinoma MDT, data system could show both medical and social value through change of medical mode.
