Objective To evaluate the effect of desflurane on blood flow velocity in the middle cerebral artery (VmMCA) and cerebrospinal fluid pressure (CSFP).Methods Sixty patients were randomly assigned to two groups. In group A,the anesthesia was maintained with desflurane, and in group B, with isoflurane. In either group, patients were allocated to three subgroups according to different doses(05,08,1.1MAC). CSFP was measured through a lumbar subarachnoid catheter before surgical procedures,from induction to administration of the inhalational agent for 45min.VmMCA was measured by transcranial Doppler at baseline , postintubation and administration of agent for 45min. Results As compared with baseline,CSFP increased gradually and reached to 16.90?4.01mmHg in subgroup 1.1MAC of group A (P0.05). Compared with baseline, VmMCA increased significantly at 45th min following administration of agent in subgroup 11MAC of group A(P005). In group A , a significant parallel correlation existed between the MAC levels and the values of VmMCA or CSFP (r=0.52,P

Objective To confirm whether the open-ended coaxial line is effective in detection of the differences in dielectric properties between colorectal cancer tissues and surrounding normal tissues and evaluation of the depth of tumor invasion. Methods The open-ended coaxial line system at frequencies ranging from 50 to 500 MHz in 98 freshly excised colorectal cancerous specimens obtained from the operating theatre of Zhujiang Hospital, was used to detect both the relative permittivity and conductivity on the serosal surface of the carcinoma nidus, the mucosa of the carcinoma nidus, and the mucosa of the surgical resection margin. Pathological examinations were conducted on each specimen after surgery. Results The values for relative permittivity and conductivity of the colorectal cancerous mucosa were significantly higher than those of the normal mucosa (P < 0.01). For the tumor which had invaded or penetrated the serosa (stage ≥ T3), the dielectric properties of both the cancerous serosa and mucosa were higher than the one restricted to muscularis propria or less intestine wall (stage < T3) over the measured frequency range, and there existed statistical differences at the common frequencies of 213 MHz and 426 MHz. Conclusion The open-ended coaxial line system may result in fast and effective diagnostic differentiation between cancerous and normal colorectal tissues as well as reasonable assessment of the tumor infiltration depth.

Magnetic induction hyperthermia becomes a very important tumor treatment method at present. In order to ensure a successful operation, doctors should make hyperthermia treatment planning before surgery. Based on Integration Healthcare Enterprise (IHE) framework and Digital Imaging and Communications in Medcine (DICOM) standard, we proposed and carried out a network workflow integrated with modern medical information systems for the dissemination of information in magnetic induction hyperthermia like accurate accessing patient information and radiology image data, storing processed images, sharing and verifying hyperthermia reports. The results proved that our system could not only improve the efficiency of magnetic induction hyperthermia treatment planning, but also save medical resources and reduce labor costs.
