Objective To establish the expression of membrane-bound HLA-G1-G4 isoforms in choriocarcinoma cell line JAR and to investigate its roles in NK cytotoxicity in vitro. Methods Stable expression of HLA-G1, -G2, -G3 and -G4 in JAR cells was established by gene cloning and transfection.HLA-Gtranscripts and protein expression in the transfected JAR cells was tested by RT-PCR, flow cytometry, Western blot and immunocytochemistry, respectively. High-affinity peptide KIPAQFYIL pulsing was performed to evaluate its effects on HLA-G expression. Effects of HLA-G1-G4 isoforms on NK cytotoxicity was performed with lactic dehydrogenase (LDH) releasing method. Results RT-PCR, Western blot and immunocytochemistry results showed that exogenous HLA-G1-G4 gene were successfully transfected and proteins were stably expressed in the HLA-G negative JAR cells; Flow cytometry data showed that only HLAG1, but not HLA-G2-G4 isoform was detectable in those transfected JAR cells and the peptide pulsing did not affect their expression status. However, all HLA-G1-G4 isoform expressed JAR cells could significantly decreased the NK cell cytotoxicity (P＜0.05). Conclusion HLA-G1-G4 isoform expression could dramatically inhibit NK-92 cell lysis, indicating that membrane-bound HLA-G isoforms are importantly immunotolerant and may play immune regulation roles in various physio-pathological situations.

Objective: To discuss the applied effect of high frequency repetitive transcranial magnetic stimulation combined with cognitive intervention for stroke patients with aphasia. Methods: 84 stroke patients with aphasia were divided into observation group (42 cases)and control group (42 cases). Patients of control group were treated by routine intervention of language training, while patients of observation group were treated by high frequency repetitive transcranial magnetic stimulation combined with cognitive intervention. A series of evaluated indicators, such as the language function score of Boston diagnostic aphasia examination(BDAE), the anxiety symptom score of Hamilton anxiety scale(HAMA), the quality of life and degree of satisfaction, were adopted to compare the post-treatment effect for the two groups. Results: After the treatment, there were statistical significance in the difference of understanding, retelling ability, reading ability and writing ability about BDAE scores between the two groups (t=3.572, t=4.482, t=6.238, t=3.013; P<0.05), and the HAMA scores of observation group was significant higher than those of control group (t=3.472, P<0.05). Besides, through different interventions, the series of indicators about quality of life, such as physical function, mental function, social function and material function, of observation group were higher than those of control group (t=4.513, t=3.923, t=4.473, t=4.033; P<0.05). And the satisfaction of observation group was significant higher than that of control group (x2=5.233, P<0.05). Conclusion: The clinical effect of high frequency repetitive transcranial magnetic stimulation combined with cognitive intervention for stroke patients with aphasia is favorable. And this method can increase quality of life and satisfaction for patients, and can extremely reduce medical dispute and improve the therapeutic level of hospital for stroke patients with aphasia.

Objective To investigate the associations between single nucleotide polymorphisms in the gene encoding human leukocyte antigen-G ( HLA-G) and the genetic susceptibility to high risk human papillomavirus ( HPV) type 18 infection in the subjects from Taizhou, Zhejiang province. Methods The genetic polymorphisms of HLA-G gene (14 bp In/Del and +3142C/G) in cervical samples collected from HPV 18-positive and healthy women were analyzed by PCR and gene sequencing technology. Statistical anal-ysis was performed by using SPSS version 16. 0. Chi-squared test was used to analyze the differences with HLA-G gene allele and genotype frequencies between healthy subjects and patients. Results Compared with healthy subjects, women with oncogenic HPV18 infection showed lower frequencies of -14 bp allele,-14 bp/-14 bp genotype and -14 bp/+3142C haplotype (P<0. 05). Moreover, lower frequencies of+3142C/C genotype were detected in HPV18-infected women with pathologically normal cervix (6. 3% vs 21. 1%, OR=0. 25, P<0. 05) and higher percentages of +3142G/G genotype were detected in women with CIN2/3 stage HPV18 infection as compared with those of the control group (68. 8% vs 35. 1%, OR=4. 06, P<0. 05). Conclusion The HLA-G gene 3′ UTR polymorphisms were closely associated with HPV18 in-fection and cervical intraepithelial neoplasia.

Objective To evaluate the dynamic changes of T lymphocyte subsets in children with hand-foot-and-mouth disease(HFMD)and to provide new evidence for the therapy and prognosis.Methods Peripheral venous blood samples of 346 HFMD cases in acute stage who were hospitalized in Beijing Ditan Hospital from May 1,2008 to August 31,2008 were collected and T lymphocyte subsets were assayed by flow cytometer.Meanwhile,T lymphocyte subsets of 67 HFMD cases in recovery phase were also detected.The pathogens were determined by reverse transcriptionpolymerase chain reaction(RT-PCR)using pharynx swab samples from 99 cases.Different samples were compared by independent-sample t test,paired t test or variance analysis.Results The average levels of T lymphocyte subsets of HFMD children in different agc groups were all lower than reference levels of healthy children in according age groups.In severe cases.T lymphocyte(TL)/lymphocyte (L)ratio in all age groups,helper T cell(Th)/L ratio in children older than 1 year,TL,Th and Th/suppressor T cell(Ts)ratio in children of 1-2 years old were all lower than those in common eases (P＜0.05).The Th/L ratio tended to increase with the disease progression.Ratios of TL/L and Th/L in common cases were increased in recovery phase(TL/L:56.3±8.6 vs 61.1±9.1,t=2.56,P＜0.05;Th/L:30.2±7.2 vs 34.9±7.9,t=2.90,P＜0.05)and all indices of severe cases except Ts/Lratio and Th/Ts ratio increased apparently in recovery phase(P＜0.01).TL[(1.738±0.976)×10~6/Lvs(2.696±1.946)×10~6/L,t=2.17,P＜0.05],Th/L ratio(25.9±7.0 vs 30.2±7.2,t=2.34,P＜0.05),Th[(0.864±0.550)×10~6/L vs(1.459±0.879)×10~6/L,t=2.90,P＜0.01]and L[(3.352±1.458)×10~6/L vs(4.664±2.435)×10~6/L,t=2.32,P＜0.05]of severe cases in acute phase were all lower than those of common cases(P＜0.05),while those were not significantly different in recovery phase between two groups(P＞0.05).The T lymphocyte subsets of enterovirus(EV)71 positive cases were lower than EVT1 negative cases,but there was no significant difference between these two groups(P＞0.05).Conclusion T lymphocyte immune responses may be correlated with HFMD onset and progression.

Objective: To study the characteristics of QT interval dynamicity in patients with heart failure (HF) and provide reference for predicting risk of sudden death in HF patients. Methods: A total of 80 inpatients with chronic HF from our department of cardiology were selected as HF group, and another 50 healthy volunteers were enrolled as healthy control group. All subjects received 24h ambulatory electrocardiography (ECG), surface ECG and echocardiography examination. Left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), QT dispersion (QTd), index for heart rate variability-- standard deviation of normal to normal RR intervals calculated over the 24 h period (SDNN) and slope of QT/RR correlated linear were measured. Results: Compared with healthy control group, there were significant increase in LVESV [(34.0±8.3) ml vs. (90.4±15.4) ml], LVEDV [(86.0±32.2) ml vs. (150.3±30.4) ml], QTd [（35.6±8.5）ms vs.（46.6±10.4）ms], slopes of QTe /RR [(0.136±0.021) vs. (0.175±0.023)] and QTp/RR [(0.130±0.026) vs. (0.158± 0.033)], and significant decrease in LVEF [(60.6±8.4) % vs. (38.5±8.8) %], and SDNN [（140.3±53.3）ms vs.（100.4±40.3）ms] in HF group, P<0.01 all.. Conclusions: Instability of ventricular repolarization in patients with heart failure makes their QT/RR slope significantly higher than that of normal subjects.
