Circulating tumor cells (CTCs) play pivotal roles for monitoring the tumor metastasis and prognosis.The nanotechnology provides a favourable platform for CTCs detection,and enables CTCs to be more promising for practical application.Meanwhile,the nanoscale device by virtue of nanotechnology has broad application prospects in eliminating CTCs and offers a new direction in the field of anti-cancer.

Mouse and rat models of type 2 diabetes mellitus play a key role in basic and clinical translational stud-ies.Different animal models should match the determined investigational objects and methods .In this review, the estab-lishments and diabetes-specific changes of various animal models were described , which will be helpful for better use of ani-mal models in research of diabetes mellitus .

Objective To study the changes in and correlations between the partial pressure of end-tidal carbon dioxide (PETCO2) and the coronary perfusion pressure during cardio-pulmonary resuscitation (CPR) based on the cardiac arrest dog models of ventricular fibrillation by electric shock. Methods 36 healthy dogs were evenly randomized into 3 groups including 4 minutes close-chest CPR(CCCPR) group, 4 minutes open-chest CPR(OCCPR) group, and 8 minutes OCCPR group. There were 12 dogs in each group, half male and half female. In the process of CPR, all parameters about PETCO2 and CPP were recorded. Results In the 4 minutes CCCPR group, the correlation coefficient between the CPP and the PETCO2 was 0.992 (P<0.05), which was in positive linear correlation. In the 4 minutes OCCPR group, the correlation coefficient between the CPP and the PETCO2 was 0.937 (P < 0.05), which also showed positive linear correlation. In the 8 minutes OCCPR group, the correlation coefficient between the CPP and the PETCO2 was 0.952 (P<0.05), and was also in positive linear correlation. The percentage of ROSC was 66.7(8/12) in the 4 minutes CCOPR group, 100%(12/12) in the 4 minutes OCCPR group and 58.3%(7/12) in the 8 minutes OCCPR group. There were statistical differences in CPP, PETCO2 between models with ROSC and without ROSC at 1, 2, 5, 10, 15 and 20 mins of CPR (all P<0.05). Conclusions This research shows that there is a close positive linear relationship between the coronary perfusion pressure and the PETCO2, and PETCO2 could be used to evaluate the prognosis of the CPR.

Carotid endarterectomy (CEA) can effectively treat symptomatic carotid stenosis, however, perioperative stroke is the most important complication of CEA. The microemboli generated before and after the operation are the most important reason for causing perioperative stroke. In addition, the hypoperfusion and postoperative hyperperfusion syndrome caused by intraoperative clipping of carotid artery, as well as carotid restenosis or occlusion after CEA are all the causes of perioperative stroke. As a non-invasive, real-time monitoring tool, transcranial Doppler (TCD) can be widely used in intraoperative monitoring of CEA, It is able to detect a variety of perioperative blood flow changes and the production of microemboli, and thus effectively predicts the occurrence of perioperative stroke, and decreases the risks of perioperative stroke.

Many datas show that thrombosis related events during chemotherapy in patients with cancer increase obviously.Thromboprophylaxis in patients receiving chemotherapy has been shown to not only improve the hypercoagulable states and effectively prevent thrombosis,but also have the potential antitumor effect and prolong the patients over survival.

Objective To analyze the postoperative complications of external fixator in treatment of elderly high-risk intertrochanteric fractures and its effect on length of hospital stay and on in-hospital fees.Methods The study involved 55 elderly patients with high-risk intertrochanteric fractures fixed with Orthofix external fixators from January 2009 to December 2011.There were 21 males and 34 females at age range of 70-79 years.All patients were associated with one underlying disease at least.Relationship of complications with patients' age,preoperative underlying diseases,surgery operation and postoperative care were analyzed.Results Common postoperative complications were lung infection (11％),screw channel exudation (25％),superficial pin tract infection (13％) and pain around the screws (22％).Factors for lung infection included the underlying lung disease and cerebral infarction before operation.Influential factor of screw channel exudation was the degree of damage to soft tissue intraoperatively.Influential factor of the superficial pin tract infection was postoperative care level.Average length of hospital stay was 5.17 days longer for patients who experienced complications after operation.Conclusions Common postoperative complications are influenced by preoperative occurrence of underlying lung disease as well as cerebral infarction,intraoperative damage to soft tissues and postoperative care level.Postoperative complications prolong the length of hospital stay and increase the treatment expense.

Gentisate (2,5 dihydroxybenzoate) pathway is one of three typical routes for bacterial aromatic catabolism Although it is less common than either of the extensively studied pathways through catechols, the gentisate pathway also plays an important role in bacterial aromatic catabolism This article reviews recent developments of this pathway, both in biochemistry and molecular biology

Objective Tanycytes(TAs) is a specialized eppendymal glia that locates mostly in the ventral lateral wall of the ventricle III and median eminence(ME).Due to its peculiar location and directly exposure to the cerebrospinal fluid,blood,neuroendocrine hormones and neurons,tanycytes play an important role in the brain barrier system,brain-CSF neurohumoral circuit and immune-neuroendocrine network.They maintain immature characters during the adulthood and have naturally conducted the neuroregeneration process in the adult hypothalamus of mammal animals.This research was designed to identify tanycytes(TAs) in postnatal 7 days of Wistar rats and then establish the cell model of TAs for further study.Methods Tanycytes of postnatal 7 days of Wistar rats were identified by the immunohistochemical technology using glial fibrillary acidic protein(GFAP) and vimentin(VIM),which are the intermediate filament markers of glia cells.The qualitative analysis was performed by the NADPH-d stain of nitric oxide sythenase(NOS).Primary TAs model was established by the cell culture technique and identified by the same methods as in vivo.Results Primary cultured TAs expressed VIM,GFAP and NOS which was identical with those in vivo.Conclusion Cell model of TAs from postnatal 7days of Wistar rats in vitro has been established and TAs could be used as a proper substrate for transplanting.
