This article described that the biology and medicine research is an important field in the international cooperation of science and technology.Meantime,by analysis on the achievements of the international cooperation from 2005 in Chinese Academy of Medical Sciences.it was shown that the intemational cooperation plays very important rule in promoting the research development in the biological and medical field.Also some principles of the international cooperation of science and technology were put forward in this article.

BACKGROUND:Fibrin glue has been widely used in breast surgery, but due to the limitation of cases, there are some differences in clinical effects.
OBJECTIVE:To systemicaly review the clinical effect of fibrin glue in breast surgery.
METHODS: We searched China Journal Ful-text Database (CNKI), VIP database, Wanfang Database for clinical randomized controled trials related to fibrin glue used in breast surgery published from March 2002 to March 2014. A Meta-analysis was done in included studies using Rev Man 5.2 statistical software.
RESULTS AND CONCLUSION:A total of 11 studies, with 1 043 cases, were enroled for the Meta-analysis. Meta-analysis showed that the postoperative 1-day drainage amount and total drainage amount were significantly lower in the fibrin glue group than the control group [WMD=-85.62, 95%CI(-128.86,-42.39), P=0.000 1;WMD=-167.27, 95%CI (-210.05,-124.49),P < 0.000 01]. In addition, the fibrin glue group was superior to the control group in the postoperative seroma rate [OR=0.30, 95%CI (0.21, 0.44),P< 0.000 01]. Application of fibrin glue in breast cancer surgery can significantly reduce postoperative drainage and seroma rate.

Objective:To analyze the clinical characteristics and laboratory examinations of hospitalized children with influenza, and improve medical personal awareness of severe influenza.Methods:Data of inpatients with influenza from November 2018 to February 2019 at Shenzhen Children′s Hospital was collected, and the clinical characteristics and laboratory examinations were statistical analyzed.Results:Of the 702 cases, 464(66.1%) cases were mild influenza, and 238 cases(33.9%)were severe influenza; the median age was 3.8 years, and 457(65.1%) cases were 0 to 5 years old.The number of patients with basic diseases and wheezing symptoms in the severe group was more than those in the mild group, with statistically significant differences(all P<0.05). The white blood cell count, percentage of neutrophils, neutrophils to lymphocytes ratio(NLR), C-reactive protein and procalcitonin in the severe group were higher than those in the mild group, while the percentage of lymphocytes was lower than that in the mild group(all P<0.05). Logistic multivariate regression analysis showed that underlying diseases, wheezing and NLR were risk factors for severe influenza.The area under the curve of NLR for severe influenza was 0.574, whose best cutoff value was 1.43. Conclusion:Influenza virus infection among children is mainly influenza A, and mostly affected children are under 5 years old.The blood routine of children with severe influenza mostly showes increased white blood cell, mainly neutrophils increased significantly, and increased C-reactive protein and procalcitonin.Children with underlying diseases, wheezing symptoms during the course of the disease, and elevated NLR are more likely to progress to severe cases, and NLR cannot be used as a independent predictor of severe influenza.

Thioredoxin-related protein 14 (TRP14),a new member of Trx family,is a novel disulfide reductase with conservative CPDC motif.Its structure and function are comparable to Trx,which is the representative member of Trx family.However,there are many differences.When tumor necrosis factor-α (TNF-α) induced cells to produce the active oxygen,TRP14 can change oxidatin state of dynein light chain(its substrate),act as a sensor of the intracellular redox state to regulate NF-κB signaling pathways induced by TNF-α,MAPK and apoptosis signaling pathways.

The present study was designed to investigate the effects of mifepristone on apoptosis of the decidual tissue cells and apoptotic correlated gene Fas/FasL expression in human early gestational period. The extent of DNA fragmentation of apoptotic cells were assessed by using an in situ terminal transferase reaction to label free 3′ ends of the DNA.The expression of Fas, FasL in the deciduas was examined by in situ hybridization with cDNA probe and immunohistochemical staining with polyclonal antibodies, respectively. The results showed that there were evident apoptosis in decidual tissues at about 40 days of gestation. Fas and FasL were strongly expressed in these decidual tissues. At about 50 days of gestation, there were a few apoptotic cells in the decidual tissues. Expression of Fas, FasL decreased at the same time. More apoptotic cells were observed in decidual tissues after adiministration of Mifepristone (RU486) in about 50 days of gestation. Fas, FasL mRNA and protein were up regulated after administration of Mifepristone. The results suggested that the induction of apoptosis by Mifepristone in decidual tissues might be one of the major mechanisms with regards to contraceptive and antigestational effects of mifepristone. Fas pathway might participate in the process of decidua apoptosis induced by RU486.

Objective To investigate the clinicopathological relation between the TNF-? and IgA nephropathy. Methods TNF-? levels in serum, urine and renal tissues of 50 patients with IgA nephropathy were measured, and 10 patients with minimal change nephrotic syndrome(MCNS) and 10 healthy subjects served as negative control group. Results The serum and urine levels of TNF-? in the patients with IgA nephropathy were significantly higher than those in the patients with MCNS and healthy subjects, and had a significant positive correlation with the degree of proteinuria and renal demage. TNF-? expression was mainly localized in the cytoplasm of the proximal renal tubular epithelial cells, and the interstitium with more monocyte-macrophages infiltration. Conclusion TNF-? took part in the onset of hematuria and proteinuria, was correlated with the degree of renal damage, and played an important role in the aggravation of IgA nephropathy.

Objective To investigate the quantitative abnormality of CD~+_5B lymphocytes in the bone morrow of the patients with autoimmunic hemocytopenia and its clinical significance.Methods The patients were referred to the Institute of Hematology & Blood Diseases Hospital,Chinese Academy of Medical Sciences & Peking Union Medical College.Quantities of CD~+_5B lymphocytes in the bone morrow of 14 patients with autoimmune hemolytic anemia(AIHA)or Evans syndrome,22 immunorelated pancytopenia(IRP)patients and 10 normal controls were assayed by FACS.The correlation between their clinical and laboratory parameters with CD~+_5B lymphocytes was analyzed.Results The qutantity of CD~+_5B lymphocytes were significantly higher in AIHA and Evans and IRP patients than in normal controls;there was no significant difference between AIHA、Evans syndrome and IRP patients.The qutantity of CD~+_5B lymphocytes in the bone morrow of all cytopenic patients showed negative correlation with C_3 complement.In AIHA、Evans syndrome patients,the quantity of CD~+_5 B lymphocytes in their bone morrow showed positive correlation with IBIL.In Evans syndrome patients,the quantity of CD~+_5B lymphocytes in their bone morrow showed positive correlation with PAIgG and PAIgM.The qutantity of CD~+_5B lymphocytes in the bone marrow of all cytopenic patients showed negative correlation with treatment response,but no correlation with the yields of CFU-E、 BFU-E、CFU-F and CFU-GM cultured from their bone marrow mononuclear cells in vitro.Conclusion CD~+_5B lymphocytes in the bone marrow of the patients with autoimmunic hemocytopenia significantly increase and are related to the disease severity and clinical response.It is suggested that CD~+_5B lymphocytes might have important roles in the pathogenesis of autoimmunic cytopenia.
