Cervical cancer poses a major threat to public health worldwide, early diagnosis of cervical cancer can improve the survival rate of patients. The detection rate of the existing cervical cancer screening methods is not very stable, and there is no reliable non-invasive index to predict the recurrence, metastasis and prognosis of cervical cancer. We searched literaruture for cervical cancer-related diagnostic and prognostic indicators and included 20 related literature, confirming that liquid biopsy is expected to replace and supplement the existing methods of screening and testing. Circulating nucleotides are an important part of liquid bioassays, including circulating cell-free DNA (cfDNA) and circulating cell-free RNA (cfRNA), among which cfRNA is a potentially rich source of tumor biomarkers, especially in the early diagnosis of cervical cancer. It has unique specificity and great potential value in the early diagnosis.

BACKGROUND:As the rapid development of oral implantation and restoration techniques, as wel as the increasing enlargement of indications, angulated abutments have been widely used. Posterior teeth region, as the weight-loading region of occlusion, can bear great force from the implants, the assessment of angulated abutments in posterior teeth region has clinical value.
OBJECTIVE:To evaluate the short-term clinical efficacy of angulated abutments on the implant denture in posterior teeth region.
METHODS:From January 2008 to January 2013, 114 patients with 175 ITI implants in the posterior teeth region were included in this study and they al underwent single-crown restoration. The involved patients were divided into angulated abutment group and straight abutment group. Periodontal probing depth, modified plaque index, modified sulcus bleeding index and peri-implant crestal bone loss in two groups were recorded at 6 months and 2 years after restoration. Cumulative survival rate of the implant denture was calculated by life-table analysis.
RESULTS AND CONCLUSION:There was no significant difference in periodontal probing depth, modified plaque index, and modified sulcus bleeding index between two groups (P>0.05). The annual crestal bone loss showed no significant difference between two groups (P>0.05). Moreover, the 5-year cumulative survival rate with 15° and 20° abutments was 95.6%, and that with straight abutment was 96.4%. The angle of abutments has no correlation with peri-implant soft tissue and peri-implant crestal bone loss, implant restorations with 15° and 20° angulated abutments may be successful y used in the posterior region, whereas the long-term effects need further research.

BACKGROUND:Hydroxyapatite/gel nano-composite has the same mechanical strength to the natural bone, but its ability to repair bone defects and osteogenic effect need to be confirmed by further studies.
OBJECTIVE:To explore the repair effect of hydroxyapatite/gel bionic composite in skul defects of rabbits.
METHODS: The hole-like calvarium defect models were established in rabbits, and treated with hydroxyapatite/ gel composites (hydroxyapatite/gel group), autologous skul as positive control (autologous bone group) and
nothing as negative control (blank group). The repairing condition in the skul defect areas were observed and analyzed by X-ray and CT at 4, 8, 12 weeks after implantation.
RESULTS AND CONCLUSION: After 8 weeks, X-ray assessment showed that normal-like bone tissue appeared in the defect region of the autologous bone group; in the hydroxyapatite/gel group, dense bone with similar
morphology to normal bone tissue was found in the central site of defect region, and the boundary was slightly blurred. After 12 weeks, the hydroxyapatite/gel showed blurred edge compared with autologous bone, and the center of the composite was disconnected; in the blank group, a clear and regular transmitted shadow was
observed. After 12 weeks, CT examination showed that the hydroxyapatite/gel was connected tightly with the surrounding normal bone tissue. As a new bionic composite, the hydroxyapatite/gel can achieve good effect in repairing skul defects of rabbits.

Objective To investigate the impact of migration inhibitory factor (MIF) over-expression on the epithelial to mesenchymal transition in human cervical cancer SiHa cells.Methods Recombinant plasmid pEGFP-N1-MIF was transfected into SiHa cells,and then of MIF mRNA relative quantitative expression was tested by RT-PCR.The mRNA and protein expression level of E-cadherin and vimentin were detected by RT-PCR and immunocytochemistry,respectively.Results RT-PCR results showed that MIF mRNA expression quantity in experimental group was higher than that in control group cells (F =2 950.278,P < 0.01).In MIF-overexpressing SiHa cells,vimentin mRNA was increased and E-cadherin mRNA was decreased determined by RT-PCR (Fvalues were 2 135.048,1 893.563,P< 0.01).Immunocytochemistry results showed that vimentin expression quantity in experimental group cells were higher than that in control group cells,however,E-cadherin expression quantity was lower than that in control group cells (F values were 2 348.021,1 789.421,P < 0.01).Conclusions The over-expression of MIF gene can significantly up-regulate the expression of vimentin,and down-regulate the expression of E-cadherin.Consequently,MIF over-expression induces epithelial to mesenchymal transition in human cervical cancer SiHa cells.

Objective To explore the diagnostic values of dual energy lung perfusion in the diagnosis of pulmonary embolism by using dual-source CT (DSCT). Methods Thirty patients with clinically suspected pulmonary embolism underwent dual-energy scanning with dual-source CT. The scanned data were integrated into three groups including 140, 80 kV and coefficient of 0.3. According to the CT pulmonary angiography (CTPA) of the fusion data, the patients were divided into pulmonary embolism group and normal group. The thin-slice reconstruction of data was analyzed using dual-energy perfusion imaging analysis software. The lung field was divided into upper, middle and lower part to make quantitative analysis of lung tissue perfusion. Paired t-tests were used in the normal patients to compare bilateral lungs, and independent samples t-tests were applied to compare the embolism group and normal group, while minimum intensity projection images (MinIP) were utilized in the assessment of lung ventilation. Results Dual energy CT showed symmetrical homogeneous perfusion in 16 normal cases, without significant perfusion defects. Quantitative analysis showed that left and right lung perfusion were (27 ± 7) and (28 ± 8 ) HU respectively, and no significant difference was found between the two sides ( t=-1.73, P >0.05 ).Perfusion of the left upper, middle and lower lung was ( 23 ± 6), (24 ± 6), and (28 ± 8) HU respectively, while the perfusion of right upper, middle and lower lung was (26 ±8), (27 ±8), and (28 ±9) HU respectively, showing no statistical significant difference between the two sides (t=-1.91, -1.96,-1.73 ,P>0.05 ). Angiography of pulmonary embolism group(14 cases)showed filling defects in the pulmonary trunk, segments and sub-segments. Pulmonary perfusion imaging showed low perfusion or defectsin lung field that dominated by embolic vessels. Quantitative analysis showed that the perfusion of the whole lung and the middle and lower lung were (22 ±5), (22 ±8), and (21 ±8) HU in the embolism group,which were significantly different from the normal group (t=-2. 10, -2.32, -2.63, P<0.05).Minimum intensity projection images showed a good consistency of abnormal ventilation zone area and perfusion abnormalities. Conclusions Pulmonary perfusion status, especially pulmonary embolism, can be analyzed by dual energy CT scanning. It helps to early discover and precisely locate the embolism.
