滑轨加齿梗滴速控制器的制作与使用

一次性输液器一般采用滑动滚轮来控制液体滴速,但滚轮很容易松动,导致临床护士常须反复调节,费时、费力,而且滴速常发生较大的变化.2007年10月我们自行研制了一种滑轨加齿梗医用输液器滴速控制器,临床应用效果较好.

Objective　To investigate whether the osteocyte apoptosis exists in orbital bones and to discuss its effect on the orbital development.Methods　Seven young Newzealand white rabbits were selected as experimental animals.At two-month-old ,all rabbits were killed and then zygomas were made into paraffin and electron microscope sections after they were decalcified.Apoptosis of osteocytes was observed by light microscope and transmission electron microscopes and detected by TUNEL staining.Results　The classical apoptosis of osteocytes was found under light and transmission electron microscopes.Apoptosis of osteocytes was diffused irregularly in the zygomatic tissue.　Conclusion　Osteocyte can apoptosis and it may participate in the development of the bony orbit.

Features Associated with Recurrence of Idiopathic Orbital Inflammatory Pseudotumor

Purpose: To explore factors which lead to recurrence of idiopathic orbital inflammatory pseudotumor (IOIP).Methods: Idiopathic orbital inflammatory pseudotumor in 209 cases between Jan 1,1978 and Dec 31, 1999 in our hospital was evaluated retrospectively. The comparison of clinical and pathological parameters between patients with at least one episode of recurrence and those with no recurrence at all was performed and analyzed using logistic regression method.Results: Follow-up results (with a mean follow-up time of 3.4 years, ranging from 0.5 year to 21.0 years) showed that the recurrence rate of IOIP was 41%. Sex and proptosis were associated with the recurrence of IOIP. Male gender was more likely to relapse than female counterparts, with the male being 52% and female being 25%.The severer the proptosis is, the higher the rate of recurrence. Among the clinical subtypes of IOIP, the rate of recurrence (17%) in cases with dacryoadinitis was the lowest, followed by anterior local orbital mass (44%), posterior orbital mass (54%),myositis (75%) and diffuse subtype (100%). However, the clinical subtypes did not show significant relationship with the recurrence of IOIP.Conclusions: Male gender and severe proptosis are associated with a higher recurrent rate in patients with IOIP.

Purpose:.To describe the magnetic resonance imaging (MRI) features of orbital rhabdomyosarcoma (RMS).
Methods:.Thirty-nine patients with histopathologically con-firmed orbital RMS were retrospectively reviewed. All patients underwent orbital conventional MRI, including axial,.sagittal, and coronal T1-weighted,.T2-weighted,.and postcontrast T1-weighted sequences. The location, shape, margin, and MRI signal of the 39 lesions were reviewed..DWI in 15 patients and susceptibility weighted imaging (SWI) in 2 patients were also analyzed.
Results:.Orbital MRI was available in 39 patients and re-vealed a soft tissue mass in the orbital region in all cases..Of the 39 patients,.the primary tumor sites were limited to the orbital proper in 31 cases, while 28 cases had extraocular muscle invasion and 8 cases had extraorbital invasion..All le-sions were unilateral..Thirty-three cases were well-defined soft tissue masses and 6 cases appeared as less well-defined soft-tissue masses..Thirty-four cases showed homogeneous isoin-tense or slightly hypointense signals on T1-weighted imaging (T1WI) and hyperintense signal on T2-weighted imaging (T2WI) compared with extraocular muscles. Five cases had heterogeneous signals with focal areas of increased signal on T1WI or decreased signal on T2WI, including 1 case with hy-pointense signal on SWI..The mean apparent diffusion coeffi-cient (ADC) value of the viable part of tumors was (0.925 ± 0.09)×10-3 mm2/s. All cases showed moderate to marked en-hancement after contrast administration.
Conclusion:Several MRI features-including homogeneous isointense or slightly hypointense signal on T1WI and slightly hyperintense signal on T2WI, relative low ADC values, and moderate to marked enhancement,.extraocular muscles inva-sion, and extraorbital extensionare helpful in the diagnosis of orbital RMS.
