OBJECTIVE:To compare the incidence of cerebral events in patients with ischemic cerebrovascular disease compli-cating with cerebral microbleeds(CMBs)at the last stage of antiplatelet agent use. METHODS:140 patients with ischemic cerebro-vascular disease were selected from Beijing Anzhen Hospital Affilicated to Capital Medical University during Jan. 2013-Jan. 2014, and then divided into CMBs group and non-CMBs group according to whether complicated with CMBs,with 70 cases in each group. After followed up for 1 year(regular use of aspirin 100 mg/d and/or clopidogrel 75 mg/d),the incidence of recurrent cere-bral infarction and cerebral bleeding and mortality were compared. RESUTLS:The incidence of recurrent cerebral infarction was 12.9% in CMBs group and 8.6% in non-CMBs group,without statistical significance(P=0.412);the incidence of cerebral bleed-ing was 10.0% in CMBs group and 1.4% in non-CMBs group,with statistical significance(P=0.029);the mortality of cerebro-vascular event at the last stage was 5.7% in CMBs group and 4.3% in non-CMBs group,without statistical significance (P=0.698). CONCLUSIONS:The risk of cerebral bleeding increase in patients with ischemic cerebrovascular disease complicating with CMBs after the application of antiplatelet agent. For patients with ischemic cerebrovascular disease complicating with CMBs,the application of antiplatelet agent should be based on the complete judgment and weighing of benefit and bleeding risk.

Objective:To explore the characteristics of human melanoma-specific antigen peptides by HLA-A2 restricted tumor-infiltrating lymphocytes.Methods:The HLA-A2 protein and polypeptides molecules were purified from the three tumor cell lines(624-Mel, Chap-Mel and JY) by immunoaffinity chromatography, after the peptides bound to HLA-A2 protein solution were acidified with acetic acid and boiled by high temperature, and centrifuged through an Ultra-CL filter, then the peptides extracts were fractionated by revered phase high pressure liquid chromatography(RP-HPLC). Individual fractions were assessed for their ability to reconstitute melanoma-specific epitopes by adding to the HLA-A2 Ag-procceing mutant cell, T2. The biological feature of one of three active peptides from RT-HPLC samples was performed by mass spectrometric analysis. The synthetic peptides identical to active peptide sequences were determined in the reconstitute test.Results:Three prominent peaks(P19, P25 and P31) of the fraction from 624-Mel were observed in the reconstitute test, TIL killing rate was 67% for (P31) peptide fraction. The mass spectrometric analysis of one of active peptides (P31) showed that at mass-to-charge ratio(m/z) 948 has been usually nine residues. The sequence is H+ Ala Lue Trp Lue Phe Phe Gly Val Lue OH-. The peptide synthesized comprising epitopes were verified.Conclusion:These results showed the peptides derived from active fractions were related to human melanoma-specific tumor antigen peptides recognized by HLA-A2-restriced TIL. These peptides could develop novel peptide-based an anti-tumor vaccine for immunotherapy of CTL.

Objective To summarize the distribution of departments,conditions of diagnosis and treatment of the syphilis patients in the general hospitals,and thus to improve the level of diagnosis and treatment.Methods A retrospective analysis of epidemiology and clinical data of 282 cases with syphilis in recent 5 years were conducted. Results The ratio of male to female was about 1:1.9.Female showed a high incidence in the 21 -50 years old,aver-age (41.68 ±0.96)years old,but for male in the 41 -70 years old,average (53.25 ±1.59)years old.The cases combined with other infectious diseases accounted to 22.0 % (62/282).The cases from the department of obstetrics and gynecology were the most (106 cases),followed by surgery (86 cases)and internal medicine (49 cases).Only 23 cases showed the clinical manifestations of syphilis in the 79 cases,which must be treated.The test rate of TRUST was only 39.0% (110/282).Furthermore,it was very low for the rate of treatment and standard treatment. Conclusion Syphilis is the most in department of obstetrics and gynecology in general hospital,and it is also com-mon in the surgery and internal medicine.The most prominent problems are that the non-special doctors had weak awareness for definite diagnosis of syphilis,and the low rate of treatment and standard treatment.

Objective To explore the value of glypican-3(GPC-3)mRNA and paternally expressed 10(PEG10)mRNA in peripheral blood in diagnosis of metastasis in hepatocellular carcinoma(HCC). Methods With SYBR Green I as fluorescence signal,real-time fluorescent quantitative reverse transcription-polymerase chain reaction was employed to detect the expression of GPC-3 mRNA and PEG10 mRNA in peripheral blood from patients with HCC with metastasis(n=8),HCC without metastasis(n=12)and hepatic cirrhosis(n=11),and receiver operator characteristics curve(ROC)and specific parameters were adopted to analyse their value in predictive and exclusive diagnosis. Results The expression of GPC-3 mRNA and PEG10 mRNA in HCC with metastasis was significantly higher than that in HCC without metastasis and in hepatic cirrhosis(P<0.05),while there was no significant difference in the expression of GPC-3 mRNA and PEG10 mRNA between HCC without metastasis and hepatic cirrhosis.In single test,the sensitivities in the differential diagnosis between HCC with metastasis and HCC without metastasis were 66.7%for GPC-3 mRNA and 72.2%for PEG10 mRNA,and the specificities were 91.7%and 91.7%.respectively.The areas under ROC were 0.748 for GPC-3 mRNA and 0.812 for PEG10 mRNA.With two markers in parallel test,the sensitivity,specificity,negative likelihood and diagnostic accuracy were 90.7%,84.O%,0.11 and 83.3%,respectively.In serial test,the sensitivity,specificity,positive likelihood and diagnostic accuracy were 60.5%,98.7%,45.5 and 73.3%,respectively. Conclusion Detection of GPC-3 mRNA and PEG10 mRNA in peripheral blood may help to predict blood metastasis and extrahepatic metastasis of HCC,and PEG10 mRNA works better than GPC-3 mRNA.The serial test of GPC-3 mRNA and PEG10 mRNA is helpful to the predictive diagnosis of peripheral blood metastasis of HCC.

BACKGROUND:Culture supernatant containing myocardiocyte has been demonstrated to induce differentiation of bone marrow-derived mesenchymal stem cel s into myocardiocyte-like cel s. This may associate with some or several cytokines in the culture supernatant.
OBJECTIVE:To explore if the supernatant of myocardiocyte induces bone marrow-derived mesenchymal stem cel s to differentiate into myocardiocyte-like cel s is associated with the different cytokine content in the supernatant of myocardiocyte.
METHODS:Bone marrow-derived mesenchymal stem cel s were isolated and cultured in vitro by the whole bone marrow adherent culture. Cardiocytes were isolated and cultured by enzyme digestion. Bone marrow-derived mesenchymal stem cel s (1×108/L) and cardiocytes (1×105/L) were cultured for 72 hours and the supernatant was col ected. Hepatocyte growth factor, insulin-like growth factor 1, platelet-derived growth factor, stem cel factor, fibroblast growth factor and vascular endothelial growth factor levels in culture supernatant of bone marrow-derived mesenchymal stem cel s and cardiocytes were detected by enzyme-linked immunosorbent assay.
RESULTS AND CONCLUSION:The content of insulin-like growth factor 1, platelet-derived growth factor and fibroblast growth factor in the supernatant of cardiocytes was significantly higher in cardiocytes group compared with bone marrow-derived mesenchymal stem cel s group (P<0.01). Results indicated that insulin-like growth factor 1, platelet-derived growth factor and fibroblast growth factor in the supernatant of cardiocytes may have capability to induce bone marrow-derived mesenchymal stem cel s to differentiate into myocardiocyte-like cel s, and insulin-like growth factor 1 may serve as the main cytokine.
