ObjectiveTo analyze the follow-up data of colorectal cancer in the Database from Colorectal Cancer (DACCA).MethodsThe information in the Dacca database was screened, and the one whose operative date and follow-up date were not blank in the total data was selected. The follow-up data were analyzed, including length of follow-up, survival outcomes, coping styles (doctors’ attitude and reaction for follow-up), follow-up path (whether to choose out-patient, Wechat, QQ tools, phone call, text message, mobile application, face-to-face), the number of follow-up (the number of out-patient follow-up, the number of telephone follow-up, and the number of follow-up within 5 years).ResultsA total of 6 437 data items were analyzed for colorectal cancer adjuvant follow-up. ① The follow-up period of five years (2004–2015) was 56.6% (3 642/6 437), and the follow-up time was 0–201, 67 (26, 97) months. ② The highest data composition ratio of survival outcomes was “Survival” (79.7%, 4 611/5 787), and in the data with five-year follow-up period (2004–2015), the highest data composition ratio of survival outcomes was “Survival” (75.0%, 2 550/3 401), and the survival rate of the five-year follow-up period in 2008 was the highest (91.4%, 235/257). ③ The highest data composition ratio of the coping styles was the doctors’ active follow-up (76.8%, 2 121/2 762). ④ The highest data composition ratio of the follow-up path was out-patient service (90.6%, 4 236/4 676). ⑤ The highest data composition ratio of the number of out-patient follow-up was conducted by the original surgical team (100%, 4 380/4 380), the specific number was 0–130、5 (2, 10) times. The data composition ratio of telephone follow-up was 86.9% (3 808/4 380) and the specific number was 0–68、0 (0, 1) times. The highest frequency of follow-up was in the first year (89.9%, 3 044/3 386) and the specific number was 0–73、5 (3, 9) times.ConclusionBy expounding the characteristics of the colorectal cancer follow-up from colorectal cancer in DACCA, it provides some references for using big data to determine prognosis.
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.
急性肺损伤( ALI) 及急性呼吸窘迫综合征( ARDS) 是各种肺内外致病因素导致的急性呼吸衰竭, 以进行性呼吸困难和顽固性低氧血症为特征, 常继发于休克、创伤、严重感染以及大面积烧伤等疾病。病理以双肺弥漫性的渗出为特点。病情进展迅速, 预后极差, 具有很高死亡率。治疗时需要纠正缺氧, 以保证组织氧供。传统的常规机械通气( CMV) 在改善氧合、呼吸力学参数以及肺内炎症反应的同时, 导致肺损伤, 即呼吸机相关性肺损伤( VALI) 。近年认为, 采用高频振荡通气( HFOV) 代替CMV 能明显避免产生VALI, 并能改善ALI/ARDS的呼吸系统顺应性和氧合作用, 减轻肺内炎症反应和VALI, 利于急性损伤肺内塌陷和闭塞的小气道和肺泡重新开放。并且有人提出HFOV 与部分液体通气( PLV)联用( HFOV-PLV) 可进一步改善气体交换, 抑制肺组织的炎性反应, 减少肺损伤及氟碳化合物( PFCs) 用量, 稳定全身血液循环, 减少中枢神经系统( CNS) 并发症[ 1] 。
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.
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.
Objective To explore the personnel framework strategy of multi-disciplinary treatment (MDT) for colorectal cancer. Methods Combined the characteristics of large public hospital, with recognized treatment pathway in international MDT for colorectal cancer and management of medical human resource, colorectal cancer MDT project team summarized a system of multi-disciplinary treatment-working for colorectal cancer of West China Hospital (MDT-CRC-WCH) by own management mechanism and subject feature. Results Based on the main four principles——whole, match, voluntary and interactive, MDT-CRC-WCH constructed reciprocation “concentric circle” with the team of directors, coordinators, colorectal surgeons, related professors, nursing and other assistants.Conclusion With construction of multi-layers, MDT for colorectal cancer is completing MDT personnel framework and suitable layers relation. And how to construct prolong active and innovative system of MDT human resource management needed more research.
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.

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.
