To study the kinetics in vivo of a Hantaan virus DNA vaccine, we constructed a fusion DNA vaccine,pEGFP/S, by cloning the S segment of Hantavirus into the vector, pEGFP-C1, which encodes Green fluorescent protein EGFP. In this report, we provide evidence that pEGFP/S was distributed and persistently expressed for more than 60 days in several organs after inoculation. Our findings suggest that the persistent immune responses induced by a Hantaan virus DNA vaccine are likely due to the plasmid pEGFP/S deposited in vivo, which acts as a booster immunization.

Objective To explore the clinical significance of the brain natriuretic peptide(BNP) in evaluating the cardiotoxicity caused by daunorubicin(DNR) through studying the changes of the plasma BNP levels in children with acute leukemia who accepted the chemotherapy with DNR.Methods Thirty-one children with acute lymphoblastic leukemia(ALL) admitted in the year of 2002-2004 underwent the chemotherapy in DVLP project.The plasma level of BNP was measured by enzyme linked immunosorbent assay(ELISA) and the left ventricular end diastolic diameter(LVEDD) by color Doppler respectively before and after the administration of DNR.Simultaneously,electrocardiography(ECG) and cardiac muscle enzymes(LDH1,CK-MB) were measured as routine.Results The plasma level of BNP increased from(3.97?2.41) ng/L to(18.25?7.63) ng/L(P

Objective To investigate the expression of CD40-CD154 co-stimulatory pathway in peripheral circulation and intestinal mucosa in patients with inflammatory bowel disease (IBD),the difference between the expression of CD40-CD154 in patients with IBD and that in healthy controls,and the correlation between CD40-CD154 levels and disease activity. Methods A total of 62 patients with Crohn's disease (CD),64 patients with ulcerative colitis (UC) and 56 healthy controls were enrolled. Enzyme-Linked Immuno Sorbent Assay (ELISA),SYBR-green real time PCR and immunohistochemical assay were respectively applied to evaluate expression of CD40-CD154 in plasma,mononuclear cells of peripheral blood and intestinal mucosa. Results Levels of CD40 (P=0. 000) and CD154 (P=0. 001) in plasma,mononuclear cells of peripheral blood and intestinal mucosa were significantly higher in patients with CD and UC than in healthy controls. However,no correlation between disease activity and CD40-CD154 expression in peripheral circulation or intestinal mucosa was detected (P ＞ 0. 05 ). Conclusion CD40-CD154 pathway activation is found in plasma,peripheral blood mononuclear cells and intestinal mucosa in patients with IBD,but is not correlated with disease activity.

OBJECTIVETo evaluate the effects of levonorgestrel-releasing intrauterine system (LNG-IUS) combined with GnRH analogue (GnRH-a) in the treatment of adenomyosis with uterine body enlargement.

METHODSTwelve women (mane age 40.3 years) with adenomyosis and uterine cavity depth over 11 cm received injections of GnRH-a every 4 weeks, and after the uterine cavity depth was reduced to below 10 cm, LNG-IUS was deployed. VAS pain score, PBAC bleeding score, uterine volume, and hemoglobin levels of the women were measured before the treatment and at 6 and 12 months after LNG-IUS placement.

RESULTSThe VAS pain score was significantly lowered at 6 and 12 month after LNG-IUS placement (P<0.05), and the PBAC bleeding score also showed significant reductions (P<0.05). The uterine volume decreased significantly at 6 and 12 months after LNG-IUS placement as compared with that before the treatment, but was significantly greater at 6 month in comparison with that at the time of LNG-IUS placement (P<0.05). Serum hemoglobin levels underwent significant increments after LNG-IUS placement (P<0.05).

CONCLUSIONLNG-IUS combined with GnRH analogue injection can be effective in the treatment of adenomyosis with dysmenorrhea and hypermenorrhea.

MicroRNAs(miRNAs) are a class of highly conserved,endogenous,small,non-coding RNAs that reg-ulate RNAi and are key regulators of tumorigenesis and development.miR-338 is abnormally expressed in most tumors. Aberrant expression of miR-338 can affect the proliferation, invasion, metastasis, angiogenesis and other physiological activities of tumor cells and play a vital role in the regulation on one or more target-genes.

ObjectiveTo explore the relationship among 25-hydroxyvitamin D,serum calcium,calcium-sensing receptor,and breast cancer. Methods The expressions of calcium-sensing receptor (CaSR) in primary breast cancer,breast benign tumors,and normal breast tissue beside tumors were determined by immunohistochemistry S-P method as well as the concentration of serum 25 (OH) D and serum calcium in breast cancer and breast benign tumors by Enzyme-linked immunosorbent assay (ELISA),Tribromoarsenazo Ⅲ method.ResultsSerum 25 (OH) D level of breast cancer was significantly lower than the breast benign tumors [ (34.13 ± 14.14) nmol/L vs (50.29 ± 25.65 ) nmol/L,t =2.870,P =0.001 ].Serum level of 25 ( OH ) D in lymph node metastasis positive patient was lower than that in negative group [ (30.8 ± 9.71 ) nmol/L vs (43.7 ± 23.59) nmol/L,t =2.467,P =0.021 ].The positive expression of CaSR in breast cancer(88.9％ )was higher than breast benign tumors(60％,x2 =6.717,P ＜ 0.01 ) and normal breast tissue beside tumors (60％,x2 =5.628,P ＜ 0.05 ).ConclusionsConcentration of serum 25 (OH)D and expression of calcium-sensing receptor in the tissues may be associated with occurrence,development and prognosis of breast cancer.

Objective To evaluate mortality associated with simultaneous bilateral or staged bilateral TKA, and better understand the risks involved in the simultaneous versus staged bilateral procedures.Methods A systematic review was conducted, following an a priori protocol, according to the methods recommended by the Cochrane Musculoskeletal Group in the Cochrane Collaboration. Eligible studies were identified in PubMed (1990-2010), OVID MEDLINE (1990-2010), and the Cochrane library, concerning postoperative complications of bilateral or staged bilateral total knee arthroplasty. All of the English-language abstracts were obtained, and retrieval words including bilateral total knee arthroplasty, staged total knee arthroplasty, and total knee arthroplasty, etc. An extensive analysis was then performed to identify articles fulfilling the inclusion criteria for the study. The details of the reported data were extracted and evaluated by two reviewers independently. Data analyses were conducted with Stata 10.0. Results Six studies met our inclusion criteria for review. The combined results showed that the prevalence of mortality[OR=2.925, 95% CI (2.352, 3.638)], mortality 30 days postoperatively[OR=5.078, 95% CI (2.192, 1 1.763)]and mortality in 70 years or older patients[OR=4.087, 95% CI (1.947, 8.582)]were statistically higher in the population that had undergone simultaneous TKA compared with staged TKA. Conclusion Compared with staged bilateral TKA, simultaneous bilateral TKA might carries a higher potential risk of postoperative mortality. Patients should be aware of this information when deciding whether to proceed with simultaneous bilateral TKA. Further well-designed and large-scale randomized controlled trials are required to confirm these findings.

Assessment mode is a bottleneck in medical education reform nowadays.Although traditional assessment tools,such as written examination,are still widely used in medical education assessments,they have obvious limitations.With the enhancement of requirements in physicians' abilities,assessments on some basic abilities of physicians are still insufficient.The United States and Europe not only focus on the curriculum reform but also the development of appropriate assessment tools,therefore,some new assessment tools are invented.These assessment tools are applicable to the formative assessment and are student-centered,being able to promote the development of education and provide new options for medical education assessments.
