Adielectrophoresis-basedmicrofluidicchipappliedtocellspatterningisdesignedandfabricated, and it demonstrates non-contact and batch manipulation of cells. The microfluidic chip employs a PDMS microchannel and two ITO electrodes, which are designed as astep shape. The distribution of electric field caused by the microelectrodes is simulated by finite element simulation software, COMSOL. The position of the maximum intensity of electric field is also determined. The ITO microelectrodes and the PDMS microchannel are fabricated using MEMS fabrication process. After oxygen plasma surface treatment, the PDMS microchannel and glass substrate with the ITO microelectrodes are aligned and bonded to form experimental microfluidic chip. Through DEP experiment with the varying frequencies, DEP response of yeast cells is examined, and the electric field frequency of the both positive and negative DEP responses are confirmed. The results showed that yeast cells in solution conductivity of 60 μS/cm had negative DEP movement at the frequency of 1 kHz to 10 kHz, positive DEP movement at the 500 kHz to 10 MHz, and no DEP movement at the 50 kHz. Under the condition of the sinusoidal potential of 8Vp-p and the electric field frequency of 5 MHz, the yeast cells were aligned into chains along the step edge of microelectrodes.

Objective To study the tactics, methods and relevant factors of interventional treatment for hemorrhage following biliary and pancreatic surgery.Methods Fourteen patients with hemorrhage following biliary and pancreatic surgery were treated by embolization using gelfoam pledgets, PVA granules, metal coils or otherwise by local infusion of vasopressin. Results There were 16 foci in 14 patients with 16 times of interventional treatment, including 3 times using metal coils, 6 times of PVA, 2 gelfoam pledgets, 1 with PVA plus gelfoam pledgets, and 4 of vasopressin. There was 1/16 time failure of using vasopressin due to anastomotic rupture. The successful rate reached 93.8%. Conclusions Interventional treatment is a safe and effective method for hemorrhage following biliary and pancreatic surgery. The key of success is the right selection of embolization or vasopressin infusion for target artery.

The measurement methods of respiration can be mainly divided into contact and non-contact.Contact detection methods include volumetric flowmeter,velocity flowmeter,temperature detection,displacement detection,impedance detection,wearable technology and sleep mattress,etc.Although these methods are noninvasive and mature,they all require electrodes or sensors to touch the body of human subjects,which limit the users’ freedom and are not suitable for severely bumed patients and newborns.In non-contact monitoring,the respiration is measured by using the media such as electromagnetic waves,optical media,etc,and without any electrodes or sensors to touch the body whiles the human subject keeping natural status.Non-contact detection method using infrared and biological radar has been a research focus both at home and abroad,which can be used for clinical,community and family care.

A total of 169 patients with short-duration type 2 diabetic mellitus (DM) were divided into atherosclerosis (AS) group and non-AS group according to the intima-media thickness (IMT) of three conducting arteries.The level of serum amyloid A (SAA) was assayed by ELISA.The results showed that SAA level of type 2 DM patients increased significantly, patients in AS group showed higher SAA level than that in non-AS group, and SAA level was positively correlated with age, body mass index, waist hip ratio and IMT of common carotid artery.Age, C-reactive protein and SAA level are the major risk factors for IMT of common carotid artery.

Objective To explore the relationship between prevalence of Kashin-Beck disease (KBD) and ecological environment, and to broaden the perspective of KBD etiology. Methods In 37 counties of KBD areas in Gansu Province, information about the ecological environment and implementation situation of control measures (altitude, temperature, rainfall, evapo ration, frost free period, annual sunshine hours, population density, per capita income, the proportion of staple food, returning farmland to forest, to forestry and replant crops) and X-ray detection rate of KBD of 7-12-year-old children in 2012 - 2014 was collected. Using four quantile regression method, the regression model was introduced to analyze the 11 ecological factors which related to the pathogenesis of KBD. The effect of three points on X-ray detection rate of KBD was estimated. Results The X-ray detection rate of KBD was independent of altitude, temperature, evaporation, population density, per capita income and cash crops, and was dependent of rainfall, frost free period, annual sunshine hours, the staple food purchase ratio, and returning farmland to forest and grassland. No matter where in any place numbered, the higher rainfall (measure value:0.003 3 to 0.006 4), the longer frost free period (measure value: 0.029 2 to 0.043 8), the longer annual sunshine hours (measure value:0.001 6 to 0.001 8), and the higher staple food purchase ratio (measure value:0.019 7 to 0.027 6), the higher risk of X-ray detection rate of KBD; the higher returning farmland to forest and to grassland, the lower risk of X-ray detection rate of KBD (measure value: - 0.037 2 to - 0.013 3). Conclusion The X-ray detection rate of KBD is closely related to local ecological environment.
