Objective To study the Val247Leu and Trp316Ser polymorphisms of β2-glycoprotein Ⅰ(β2GPⅠ) in systemic lupus erythematosus (SLE) patients and their associations with antiphospholipid antibodies and thrombotic complications.Methods We used DNA sequencing to detect the polymorphisms of Val247Leu and Trp316Ser in 378 SLE patients and 240 normal controls.Anti-β2GP Ⅰ antibodies and anticardiolipin (ACA) were tested by enzyme linked immunosorbent assay (ELISA).Lupus-type anticoagulants(LAC) was performed by diluted Russell's Viper Venom Test.Then the patient group was further analyzed according to APLs (Anti-β2GP Ⅰ antibody,LAC and ACA),thrombosis and obstetrical complications using Logistic regression analysis to confirm whether there are associations between β2GPⅠpolymorphism and those factors.Results For Va1247Leu,the predominant genotype was LL in healthy controls which accounted for 57.08%,while it was VL in SLE patients which accounted for 59.5% (x2=45.01,P=0.000).Frequency of VV genotype was significantly higher in patients with thrombosis,anti-β2GP Ⅰ,ACA and obstetrical complications (OR=6.79,3.75,2.12 and 3.85,respectively;P=0.000,0.001,0.044 and 0.017,respectively).Those patients with VL genotype tended to have positive anti-β2GPI,LAC,ACA,thrombosis and also obstetrical complications (OR=2.95,1.88,2.47,2.97 and 2.74,respectively;P=0.000,0.007,0.000,0.001 and 0.016,respectively) than those negative ones.The predominant genotype of Trp316Ser was TT,then TS.No correlations could be found between Trp316Ser polymorphism and APLs,neither relation to thrombosis complications.Conclusion The polymorphism of Val247Leu is significantly associated with the presence of APLs,thrombosis and obstetrical complications.Both VV and VL genotype are risk factors for the generation of APLs,occurrence of thrombosis and obstetrical complications.The VV genotype is a high risk factor for thrombosis.Trp316Ser polymorphism does not contribute to the APLs production and also have no correlations with thrombotic complication.

Objective To explore the correlation between B lymphocyte activation and CD154 expression and lupus anticoagulants (LAC) in patients with systemic lupus erythematosus (SLE). Methods Sixty newly diagnosed SLE patients (SLE group) and 32 healthy controls (control group) were involved. The expressions of CD27 and CD154 in peripheral blood were determined by flow cytometry, and the positive expression rates were computed. The LAC was determined by activated partial thromboplastin time, and the LAC ratio > 1.20 was positive. Results The positive rate of CD27, expression intensity of CD27, positive rate of CD154 and expression intensity of CD154 in SLE group were significantly higher than those in control group: 0.047 ± 0.021 vs. 0.035 ± 0.014, 0.387 ± 0.185 vs. 0.214 ± 0.091, 0.191 ± 0.108 vs. 0.101 ± 0.081 and 0.049 ± 0.018 vs. 0.022 ± 0.012, and there were statistical difference (P<0.05 or <0.01). Among patients with SLE, the LAC positive was in 28 cases, and the LAC negative was in 32 cases. The positive rate of CD27, expression intensity of CD27, positive rate of CD154 and expression intensity of CD154 in SLE patients with LAC positive were significantly higher than those in SLE patients with LAC negative: 0.055 ± 0.023 vs. 0.037 ± 0.014, 0.444 ± 0.179 vs. 0.329 ± 0.123, 0.218 ± 0.101 vs. 0.158 ± 0.044 and 0.058 ± 0.035 vs. 0.020 ± 0.009, and there were statistical differences (P<0.05). Conclusions The B lymphocyte activation and CD154 abnormal expression correlates with generation of LAC in patients with SLE. It provides a basis for the further study on intervening the generation of LAC and reducing the risk of thromboembolism.

Objective To establish the Cookie Theft Test for Chinese norms. Methods 29 normal participants and 17 patients with stroke finished the Cookie Theft Test. The language samples were analyzed in 7 different indexes which are incorrect statement (IS), dysfluencies (DF), providing structure support (PS), repetitions (RP), content units (CU), elaborations of content units (EC) and irrelevancies (IR). Besides, the total words of language samples were counted. The scores of normal participants in 8 indexes were regarded as norms. And the scores of patients in 8 indexes were used to test the validity of the norms. Results The test-retest reliability was r(IS)=0.92, r(DF)=0.89, r(PS)= 0.98, r(RP)=0.84, r(CU)=0.96, r(EC)=0.88 and r(IR)=0.99, respectively. 12 out of 17 patients were distinguished by the norms. Conclusion The norms of Cookie Theft have acceptable reliability and validity and can be applied to clinical diagnoses and scientific researches

We summarized the epidemiological investigation results of the first case of human infection with avian influenza A(H9N2) virus in Chengdu,China,in order to provide references for dealing with similar diseases scientifically in the future.The methods of field epidemiology and laboratory testing were used to collect the H9N2 case's clinical and epidemiological data,as well as collect and test the samples of the H9N2 case and the relevant environment,so that the possible sources of infection,the epidemiological characteristics and clinical features could be analyzed.Results showed that the H9N2 case contacted with poultry within 10 days before the onset of illness and the H9N2 virus nucleic acid was detected in the patient's specimen by PCR.This case suffered from several chronic diseases for a long time,although active treatments were taken this time,she died soon after onset.Her living environment,the chicken leftovers from cooking,and surrounding poultry markets were polluted by H9 avian influenza virus.Through the investigation,we could deduce that the infection source of this case was the chicken infecting H9N2 viruses from surrounding poultry markets.This would be the first fatality associated with influenza A (H9N2) virus infections in humans.And though avian influenza A(H9N2) virus was low pathogenic,infection could cause severe symptoms or death in people with severe underlying diseases.

Objective To explore antitumor effect of 131I-Trastuzumab on human epidermal growth factor receptor(HER) 2 overexpressing breast cancer cells and investigate its possible mechanism.Methods The expression levels of HER2 of three different breast cancer cell lines (BT474,MCF-7,HCC1937) were detected with immunofluorescence.Trastuzumab was labeled with 131I using the Iodogen method and 131I-Trastuzumab was isolated with ultrafiltration membrane,then the labeling efficiency,radiochemical purity and immunoreactivity were measured.The effects of 131I,Trastuzumab and 131I-Trastuzumab on viability of BT474 cells were evaluated with cell counting kit-8 (CCK-8) assay.The levels of total Akt and phosphorylated Akt (p-Akt) were detected with Western blot analysis.One-way analysis of variance (ANOVA),ANOVA for factorial design,Bonferroni correction and Pearson correlation analysis were used for data analysis.Results The expression level of HER2 in BT474 cells was much higher than those in HCC1937 and MCF-7 cells.The labeling efficiency,radiochemical purity and immunoreactivity of 131I-Trastuzumab were (89.71± 2.93)%,(91.80±1.43)% and (58.84±3.35)% respectively.131I (4.625 GBq/L),Trastuzumab(125.0 rmg/L) and 131I-Trastuzumab(4.625 GBq/L) exhibited a dose-dependent cytotoxicity against BT474 cells (r =-0.964,-0.912,-0.618;all P<0.05).The cell viability of 131I-Trastuzumab treated gourp (34.73% ±5.03%) was significantly lower than those of 131I and Trastuzumab treated groups (64.36%± 1.51% and 58.09%±4.14%;t=10.373 and 8.180,both P<0.05),and the cell viability of control group was (100.00±4.54)%.131I-Trastuzumab shown a positive multiplicative interaction between 131I and Trastuzumab (F=9.226,P<0.05;CDI =0.929).Western blot results showed that there was no significant difference of total Akt expression among the control group,131I group,Trastuzumab group and 131I-Trastuzmab group (F=0.208,P>0.05).P-Akt expression in both Trastuzumab group and 131I-Trastuzumab group were much lower than those of control group and 131I group (t=12.524,15.984,7.347,10.807;all P<0.05),while there was no significant difference of p-Akt expression between Trastuzumab group and 131I-Trastuzumab group(t =3.460,P>0.05).Conclusions 131I-Trastuzumab may kill HER2 overexpressing breast cancer cells more effectively than Trastuzumab alone.The underlying mechanism may be attributed to that 131I-Trastuzumab may enhance the radiosensitivity by the inhibitory effect on PI3K/Akt pathway and thus exert synergistic effects with 131I.

Objective To investigate the G protein-coupled receptor kinase 2 (GRK 2) level in peripheral blood lymphocytes with cardiac func-tion in elderly patients with acute myocardial infarction. Methods This study enrolled 40 patients with acute ST-segment elevation myo-cardial infarction (STEMI) and 40 patients with unstable angina. All patients were 65 years or older. Cardiac function was evaluated by echocardiography, and the GRK 2 level in peripheral blood lymphocytes was measured. Patients with STEMI were followed up for 2 years. Results The GRK 2 level in peripheral blood lymphocytes was significantly higher in patients with STEMI than in patients with unstable angina, and was negatively correlated with left ventricular ejection fraction, cardiac output, stroke volume, and left ventricular fractional shortening. The GRK 2 level was significantly elevated in some patients with acute STEMI and poor cardiac function. Conclusions In-creased GRK 2 level in patients with acute STEMI may contribute to poor myocardial systolic function and myocardial remodeling. Meas-urement of the GRK 2 level in peripheral blood lymphocytes may assist in the evaluation of cardiac function and myocardial remodeling in elderly patients with acute STEMI.
