Objective To investigate the value of three-dimensional color power angio(3D-CPA)in the prenatal diagnosis of pernicious placenta previa (PPP ) with placenta increta.Methods The ultrasonographic findings of PPP with placenta increta diagnosed in our hospital by 2D-CDFI and 3D-CPA were reviewed and compared with pathologic histology examination.For each of the two imaging methods, sensitivity,specificity,positive predictive value and prenatal diagnose accordance rate were summarized. Results For 3D-CPA,sensitivity,specificity and positive predictive value were 91.1%,88.9% and 93.3%, respectively.The results of 3D-CPA were higher than those in 2D-CDFI (sensitivity 76.4%,specificity 66.7%,positive predictive value 81.5% ),and were statistically significant (P <0.05 ).The diagnose accordance rate of 3D-CPA was statistically higher than that of 2D-CDFI (90.4% vs 73.0%;P <0.05). Conclusions 3D-CPA can display abnormal vascular reconstruction between the placenta and uterine wall from various angles,and is more accurate than 2D-CDFI.3D-CPA plays an important role in the prenatal diagnosis of PPP with placenta increta.

Objective To study the clinical significance of magnetic resonance imaging in evaluation of diagnosis and treatment of tibia plateau fractures accompanying with knee joint injures.Methods From July 2000 to November 2005,52 cases of tibia plateau fractures were examined by X-ray and Magnetic resonance imaging(MRI),which could accurately diagnose the splitting and depression degree of tibia plateau fractures and the knee joint injures.Results There were 52 cases of tibia plateau fractures,including 14 cases lateral plateau fractures,11 cases medial plateau fractures,11 cases total plateau fractures,18 cases tear-off fractures of tibia.MRI could accurately display fractures accompanying with knee joint injures,including fragmentation of catilago articularis,lancination and displacement of meniscus,lancination of collateral.According to MRI displacement direction of tibia plateau fractures and areas of depression could be accurately evaluated before operations.Conclusion MRI can accurately diagnose the feature of tibia plateau fractures and knee joint injuries.And according to the scope of fractures,the best treatment methods can be chosen.

NAD +-dependent cytosolic glycerol-3-phosphate dehydrogenase in Sacch aromyces cerevisiae is one of the key enzymes in metabolic pathway of glycerol . catalysing the reduction of dihydroxyacetone phosphate to glycerol-3-phosph ate.It has two isoenzymes.To study the differences between their structures, their expression of encoding genes and their functions may help increase the understan ding of the cell response mechanism to the hyperosmotic and anoxic conditions. In this paper the research on the two isoenzymes was reviewed.

We reported perioperative nursing care of a patient with autogenous frozen ovarian pelvic transplantation after cervical cancer radical hysterectomy.Nursing priorities included:preoperative multidisciplinary assessment of the patient,including assessment of physical condition,activity of frozen frozen ovarian tissue and appropriate recovery time,autologous transplantation site,psychological status,and corresponding nursing interventions were provided.Nurses cooperated with surgeons during frozen ovarian resuscitation and other related operations.Health education and discharge guidance were provided after surgery,and the patient was informed about the importance of revisit and self-monitoring.The surgery was successful and the patient was discharged 3 days after surgery.There was no significant change in endocrine levels during revisit one month after surgery,but the patient considered symptoms of menopause had alleviated.

Objective To investigate the effect of lateral ventricle transplantation of neurotrophic factor-transfected cells derived from Glia cell line on vascular dementia in rats and gene expression of Drebrin in hippocampal region.Methods By using gene clone technique,the GDNF gene was transfected into SH-SY5Y cell lines.104 adult male Sprague-Dawley rats weighing (200± 20) gram were divided into groups:transplanted group,injected group,control group,all of which accepted operation by permanent ligation of left common carotid artery and clipping right common carotid artery repeatedly to build up model of vascular dementia,and sham operation group which accepted no ligation or clipping.6 rats from each group were decapitated on the third day,seventh day and tenth day after transplanting treatment were for fluorescence detection.The rest 20 rats in each group were used to detect learning and memory functions by Morris water maze on the third day and decapitated on the fourth day after transplanting treatment.Then GDNF level in temporal lobe were detected by enzyme-linked immunosorbent assay (ELISA),while Drebrin mRNA and protein levels in hippocampal region were detected by real time-PCR and Westernblot respectively.Results There was strong fluorescent light detected around lateral ventricle of rats in transplanted group on the third day after transplantation,which faded on the seventh day and disappeared on the tenth day.The learning and memory functions of rats in transplanted group were improved significantly.The escape latency was shorter in transplanted group than in injected group and control group [(34.89±4.15) s vs.(43.86±6.95) s,(50.89±3.66) s,both P＜0.05],while shuttle times through the third quadrant were more often in transplanted group than in injected group and control group [(11.00±1.49) vs.(9.26 ±1.38),(8.04 ± 1.12),both P＜0.05].GDNF level and Drebrin mRNA and protein levels were higher in transplanted group than in injected group and control group [GDNF:(315.71±27.43) vs.(256.26±19.90),(141.95±21.33),Drebrin mRNA:(5.54±0.35) vs.(3.10±0.33),(1.32±0.23),Drebrinprotein:(0.55±0.05) vs.(0.43±0.06),(0.26±0.06),all P＜0.05].Conclusions GDNF-transfected cells could survive in the lateral cerebral ventricle of rats for about seven days.The method for treating vascular dementia through the technique of transplanting GDNF-transfected cells is certain feasible,which has a better therapeutic effect than GDNF-injection directly into lateral cerebral ventricle.The therapeutic effect of GDNF on vascular dementia may be related to its action of regulating neural plasticity.

Osteoarthritis (OA) is the main reason of joint pain and dysfunction in the elderly in China, and its incidence is increasing year by year. In addition to the joint peripheral osteophyte formation and degeneration of articular cartilage, in?flammation, as one of the dominant pathological changes in OA, is causing more and more attention. Pro-inflammatory cyto?kines (PIC) are important mediators of inflammation. The increased level of PIC in OA can lead to systemic and local inflam?mation, results in further destruction of many kinds of tissues in joint (such as cartilage), and accelerates the development of OA. Besides, the severity of inflammation is closely related to the clinical symptoms of OA. Therefore, it is important to un?derstand the role of PIC in the pathogenesis of OA. From the perspective of the relationship between pro-inflammatory fac?tors and OA and the molecular mechanism, this article reviews the research progress in this field, which provides new con?cepts for diagnose and treatment of OA.
