BACKGROUND: Measuring the slope of proximal tibiofibular joint may elucidate the anatomical structure and type of proximal tibiofibular joint, and evaluate the stability of proximal tibiofibular joint. OBJECTIVE: To investigate the measurement methods and clinical significance of the joint slope by comparing the slope measurement of bilateral proximal tibiofibular joint surface on X-ray and 64-row spiral CT reconstruction.METHODS: One hundred normal adult volunteers, including 50 males and 50 females, aged 18-90 years, were photographed in double knees via internal rotation to 30°, 45° and 60°, respectively and scanned with 64-row spiral CT, tibiofibular bone (including knee joints) was reconstructed. The included angle between proximal tibiofibular articular surface and the longitudinal axis of the fibula shaft, between the proximal tibiofibular articular surface and the horizontal line, were measured using an angle square.RESULTS AND CONCLUSION: There were great variations of the data in the same proximal tibiofibular joint measured by X-ray and spiral CT. X-ray results are affected by the site of photograph position, and the slope of articular surface is estimated, so the 64-row spiral CT is an accurate and convenient method to reconstitute the slope of proximal tibiofibular joints. Spiral CT could be used to distinguish the dislocation and instability of the proximal tibiofibular joint, accordingly reduce the clinical misdiagnosis.

Objective To explore the potential of autologous dendritic cells (DC) pulsed with HLA-A201-binding peptide E613-21(KLPDLCTEL) and E786-94(TLGIVCPI)in inducing specific T cells respouse in vitro.Methods Cervical carcinoma patients with positive HLA-A201 were enrolled and their monocytes isolated and induced into dendritic cells and pulsed with HLA-A201-binding peptide E613-21 and E786-94.PBLs were primed by DCs every week for thee times.The cytokine level of supernatant of CTLs was tested by ELISA.The percentage of special CTLs was tested by flow cytometry.The specific killing effect of CTLs was tested by MTT.Results the numbers of DCs of eleven cervical carcinoma patients were (10.79±0.88) ×106(100 ml peripheral blood).CDllc+HLA-DR+(97.15±2.41)％,CD80+(84.28+5.39)％,CD83 +(85.17±5.06) ％,CD86 + (97.74+0.87) ％.Proliferation index of PBLs primed by DCs three times was 15.4± 1.5.Cytokine levels including IL-2,IL-12,IFN-γ and TNF-α were obviously higher than nonpriming PBLs[(2551.9+195.3) pg/ml,(554.9±64.0) pg/ml,(2416.9±281.7) pg/ml,(632.4 +71.1)pg/ml,respectively] (P＜0.05),but IL-10 was no significant difference between priming CTLs and nonpriming CTLs.The average percentage of special CTLs was obviously higher than control group[(6.32±1.54)％,P＜0.05].The killing effect of CTLs was obviously higher than control group(P＜0.05).Conclusion Dendritic cells pulsed with peptide E613-21 and E786-94 can induce special CTLs in vitro and stimulate CTLs secret cytokines.This will provide science basis for research of therapeutic HPV vaccine.

Objective To study the expression of PINCH and vascular endothelial growth factor C (VEGF-C) in cervical squamous cell carcinoma.Methods We detected the expression of PINCH and VEGF-C by immunohistochemistry SP in 58 cervical squamous cell carcinoma cases and 30 normal cervical epithelial tissue and analyzed their relationship to the clinical pathological features.Results The expression of PINCH and VEGF-C in 58 cervical squamous cell carcinoma(62.1％,36/58 ;67.2％,39/58 ) were higher than that in normal cervical epithelial tissue(0,0/30).The difference was significant( x2 =31.512,12.534,P ＜ 0.001 ).The expression of PINCH protein was not significantly associated with the age,tumor size and tumor differentiation grade ( P ＞ 0.05 ),but was associated with the lymph node metastasis and clinical stage ( x2 =9.090,8.236,P ＜ 0.001 ).The expression of VEGF-C had no significant correlationship with the age and tumor size( P ＞ 0.05 ) but had a correlationship with the lymph node metastasis,tumor differentiation grade and clinical stage( x2 =10.775,13.496,5.001,P ＜ 0.05 ).The expression of VEGF-C was correlated with the expression of PINCH protein( C =0.341,P ＜ 0.01 ).Conclusion It is possible that VEGF-C and PINCH take part in the development and progress of cervical squamous cell carcinoma and play an important role in the invasion and metastasis mechanism altogether.

Objective To investigate the safety and clinical response of dendritic cells (DC)vaccine loaded with HLA-A2-restricted peptides MAGE-3、 Tyr、 MART-1 and GP-100 against malignant melanoma. Methods Twenty three HLA-A2 positive patients with malignant melanoma were enrolled.Peripheral blood mononuclear cells were separated into adherent cells for induction of DC loaded with four peptides. DC vaccine was administered subcutaneously once a week in inguinal region. The immunological responses and clinical responses were evaluated. Results Dendritic cell vaccination were well tolerated in all patients and there was no toxicity observed. Serum levels of IL-2, IL-12 and IFN-γincreased significantly after first vaccination and fourth vaccination. The positive rate of DTH test was 50% (5/10), and 2 fold increase of CD8+ IFN-γ+ cells were observed in 6 of 10 patients. Stable disease was observed in 11 of 23 patients, one patient had a complete metastasis regression, four patients had 50% regression of metastasis,four patients had a minor response, and disease progressed in three patients. Conclusion DC vaccines loaded with peptides MAGE-3、 Tyr、 MART-1 and GP-100 can elicit non-specific and specific immune responses, leading disease control. DC vaccine is considered one of safe and effective treatments for malignant melanoma.
