In autoimmune thrombocytopenic purpura (AITP) specific autoantibodies bind platelet GP via their Fab fragments. Both splenic CD5+ B and CD5- B cells produce platelet glycoprotein-specific antibodies. There is limited number of antigenic determinants, and the GP-specific autoantibodies are derived from a restricted number of B-cell clones in chronic AITP. Blocking co-stimulatory signals could induce platelet-specific T cell anergy. MMF could be used as a second line agent for the treatment of steroid-resistant AITP. Detection of plasma thrombopoietin levels play an important role in the differentiation of thrombocytopenic states caused by platelet destruction or due to bone marrow hypoplasia. Endogenous TPO level is also important on the differential diagnosis of ET and RT. Quinine- or heparin-dependent antibodies could induce thrombocytopenia. PCR-SSP is useful for the genotyping of the platelet-specific alloantigen HPA. Biotinylated platelets have an impaired response to agonists as evidenced by in vitro platelet aggregation tests.

BACKGROUND:Currently, what we know about exosomes is that it can be produced by a variety of cel s and transfer a variety of materials, producing subsequent function of regulation.
OBJECTIVE:To review the function of exosomes in mesenchymal stem cel differentiation, in order to provide reference for further in-depth study.
METHODS:With the key words of“exosome, mesenchymal stem cel , differentiation”in Chinese and English, respectively, a computer-based search was performed for articles published in CNKI, Medline and Embase databases from January 2001 to September 2016. After the initial screening, the reserved articles were further detailed, summarized and concluded.
RESULTS AND CONCLUSION:Exosomes are a kind of vesicles 40-100 nm in diameter, which can be secreted by a variety of cel types, containing functional products, such as functional protein, gene product, lipid and so on. As a bridge of adjacent cel s transferring functional products, exosomes are becoming an issue of concern in the microenvironment for cel interaction. In the differentiation of mesenchymal stem cel s, exosomes also play an indispensable role via pathway regulation.

BACKGROUND:Artificial valve replacement for valvular disease has good biocompatibility and hemodynamic characteristics, but there are stil many factors that affect its therapeutic effects. OBJECTIVE:To detect the level of serum Apelin-12 in the perioperative period of valve replacement in valvular disease patients with atrial fibrilation. METHODS: Sixty-two patients with valvular heart disease scheduled for artificial valve replacement were selected, including 30 patients with persistent atrial fibrilation (atrial fibrilation group) and 32 patients with sinus rhythm (sinus rhythm group). There were 33 males and 29 females, with a mean age of (55±11) years. Levels of serum Apelin-12 and makers related to inflammation and oxidative stress were detected in two groups at admission. Furthermore, the sinus rhythm group was sub-divided into postoperative atrial fibrilation (POAF) group (n=8) and non-POAF group (n=24) after valve replacement, and the above-mentioned indicators were detected and compared between these two subgroups. RESULTS AND CONCLUSION:Compared with the sinus rhythm group, the serum level of Apelin-12 was significantly lower in the atrial fibrilation group, while the levels of high-sensitivity C-reactive protein and interleukin-6 and total antioxidant capacity were significantly higher in the atrial fibrilation group (P <0.05). Correlation analysis showed that the serum level of Apelin-12 was negatively correlated with high-sensitivity C-reactive protein level and total antioxidant capacity (r=-0.265,P=0.045;r=-0.960,P <0.001), but not correlated with the interleukin-6 level (r=-0.155,P=0.230). Compared with the non-POAF group, the serum level of Apelin-12 was significantly lower in the POAF group (P< 0.05), but the left atrial diameter, high-sensitivity C-reactive protein level were higher in the POAF group (P < 0.05). Apelin-12 may take part in the occurrence and maintenance of atrial fibrilation through the regulation of inflammations and oxidative stresses. The testing of serum Apelin-12 has a certain value in predicting the occurrence of postoperative atrial fibrilation.

Objective To investigate the diagnostic value of CA125 and CA153 for the combined detection of the disease in breast cancer patients.Methods 100 cases of breast cancer patients were selected as the breast cancer group,and the same period 100 cases of benign breast lesions were selected as the benign group,100 cases of normal healthy subjects were selected as the control group.The expression levels of CA125 and CA153 in the three groups were detected.Results CA153 and CA125 levels in the breast cancer group was (78.4 ± 23.76) U/mL,(71.3 ± 24.7) U/mL; The benign group CA153 and CA125 content were (13.4 ± 3.7) U/mL,(20.6 ± 12.4) U/mL;CA153 and CA125 in the normal control group content were (0.9 ± 0.8) U/mL,(19.3 ± 11.3) U/mL; CA153 and CA125 in the breast cancer group were significantly higher than those of the benign group and the normal control group,the difference was statistically significant (F =34.15,28.42,all P ＜ 0.05) ; CA153 and CA125 alone detected in breast cancer detection rate was 31.0 ％,24.0 ％,respectively,combined detection of CA153 and CA125 in breast cancer detection rate was 66.0％,CA153 and CA125 alone detected in breast cancer detection rate was significantly lower than the combined detection CA153 and CA125 in the breast cancer detection rate (F =8.21,P ＜ 0.05).CA153 and CA125 expression of breast cancer patients after treatment than that of before treatment significantly reduced,and compare the data with statistically significant (t =21.82,22.31,all P ＜ 0.05).Conclusion The clinical detection of CA125 and CA153 united can effectively improve the diagnosis of breast cancer effect,combined detection of higher sensitivity and specificity.Meanwhile,the combined detection of breast cancer clinical monitoring also ha ssome significance,which is worthy of clinical application.

Objective To test the hypothesis that attachment of synovial cell to &?2-microglobulin modified with advanced glycation end products (ACE-?2m) would affect cell adhesion, spreading and proliferation.Methods Normal human synovial cells (type B cells) were isolated and plated in culture dishes coated with AGE-?2m or with normal extracellular matrix proteins (EMP). Adhesion was analyzed by counting the isotope-labelled cells. Spreading was tested using a light microscope and proliferation determined by 3H-TdR incorporation and counting the number of cells. Results Synovial cells adhered less effectively to AGE-?2m, ?2m and AGE-collagen than to the normal EMP (collagen and fibronectin). Cells interacting with AGE-?2m, ?2m or AGE-collagen also demonstrated less extensive spreading throughout the examined time intervals (60-120 minutes after plating), and decreased 3H-TdR incorporation and cell numbers after 72 hours of plating when compared to cells interacting with normal EMP. Conchusion AGE-?2m in amyloid may alter synovial cell behavior in situ in ways which cods contribute to the development of dialysis-related amyloidodsis(DRA).
