Purpose To explore the role of scanning laser tomography in the assessment of macular hole surgery. Methods Fifteen eyes of 14 patients with macular holes underwent scanning of their affected macular area using the Heidelberg retina tomograph (HRT). The significance of topographic changes postoperatively were determined in eleven eyes which received vitrectomy surgery. The scan field was set at 15? of the retina and the depth was set to 1.5 mm or 2.0 mm. All the measurements were taken for 3 times and the average value of the 3 measurements was used. Results The average hole area was (0.499?0.34) mm 2 and the maximal depth of the hole was (0.284?0.11) mm. Topographic difference analysis of the eleven eyes showed a significant reduction in the height of the retina after vitrectomy. The maximal depth of the hole was (0.063?0.04) mm postoperatively. Conclusion Scanning laser tomography provides an objective evaluation of the anatomic outcome of the macular hole surgery.

Objective To study the effects of cool restrain stress on the accumulation of eosinophils and expression of Th cytokines in rat nasal mucosa with allergic rhinitis model.Methods Fifty healthy female rats were randomly divided into 5 groups:control group,allergic rhinitis(AR)group,AR plus stress group,stress plus AR group and simultaneous stress-AR group.Cool restrain stress,AR model and simultaneous stress-AR were made.Nasal mucosa of septum from rats of five groups were stained routinely by haematoxylin eosin(HE)and immunohistochemistry respectively.The density of eosinophils and expression of interleukin(IL)2,IL-6 were observed by using software of image analysis systems under microscope.Results The density of eosinophiles and IL-6 in the nasal mucosa of stress-AR group were significantly higher than those in AR[(14.1 ± 3.2)for eosinophiles,and(15.3 ± 4.8)for IL-6]and were also significantly higher than those in control groups[(2.3 ±1.4)for eosinophiles,and(4.9 ±2.4)for IL-6)],and the differences reached statistical significance.(F were respectively 7.06,7.14,8.54,8.20,P were respectively＜0.05 or＜0.01),but no significant differences of the three groups(AR plus stress,stress plus AR and simultaneous stress-AR groups)were found(F were respectivel 2.90 and 3.20,P＞0.05).The expression of IL-2 in nasal mucosa of stress-AR group was significantly reduced compared with AR and control groups(F were respectively 7.27,7.32,P were respectively＜0.05 or＜0.01).But there were also no significant differences of the three groups(AR plus stress,stress plus AR and simultaneous stress-AR groups,F=3.12,P＞0.05).Conclusions The abnormal infiltration and accumulation of eosinophiles and the differences in expression of IL-2 and IL-6 which represented Th1 and Th2 cytokines in rats nasal mucosa varied in different groups.The eosinophiles and IL-6 were rarely expressed in control group and moderately expressed in AR group,but significantly expressed in cool restrain groups.The IL-2 representing Th1 cytokines were reduced in cool restrain stress gruops.All these results indicated that cool restrain stress might play a role in inducing rat allergic rhinitis.

ObjectiveTo evaluate the biomechanical stability and the clinical efficacy of the percutaneous pedicle screw fixation in the treatment of thoracolumbar fractures. Methods Twelve lumbar fracture models were made on fresh calf lumbar spine specimens to compare the stability of the 4 monoaxial screws and 4 muhiaxial screws transpedicular fixation by examining the range of motion(ROM) in flexion,extension, lateral bending, and torsion. Sixty cases of thoracolumbar fractures without neuro-deficiency were treated surgically, 11 of the minimally invasive group(monoaxial screw group) and 18 of the open surgery group(multiaxial screw group) were followed up more than 12 months. ResultsThe 4 monoaxial screws transpedicular fixation specimen exhibited a smaller ROM significantly in flexion, extension compared withthe 4 multiaxial screws transpedicular fixation specimen. The 4 monoaxial screws transpedicular fixationspecimen exhibited a significantly smaller ROM in flexion and extension than the intact specimens. TheROM in the 4 multiaxial screws transpedicular fixation specimen and the intact showed on significant differences. There were no significant differences between the two groups in the preoperative and postoperative anterior fractured vertebral height (AVH) and the Cobb's angle (CA), but there were significant differences in the AVH and the CA between preoperative and postoperative in the two groups. There were significant differences in the correction loss of the AVH between the two groups at final follow-up.ConclusionThe percutaneous pedicle screw fixation using Sextant system is a good minimally invasive surgical choice for patients with thoracolumbar fractures without neuro-deficiency, but which has a loss of the AVH and worse flexion-extension stiffness in follow-up compared with the open monoaxial screws fixation.

Objective Therapeutic hypothermia has become a standard neuroprotective treatment in term newborn infants following perinatal asphyxia,but active cooling with whole body surface or head cooling is both complex and expensive.The clinical feasibility of passive cooling in treatment of full term infants with severe asphyxia was investigated.Methods Thirty-two severe asphyxiated term newborns treated with hypothermia were analyzed,who were randomly divided into 2 groups:passive cooling group(n =17) and active cooling group(n =15).Active cooling group adopted MTRE ALLONTM-thermo regulatory systems,passive cooling group using natural cooling method.Hypothermia treatment time was 72 hours.At the end of treatment,the clinical manifestations,biochemical parameters and clinical efficacy of infants between the 2 groups were compared.Results During treatment all infants had no cardiac arrhythmia,hypoglycemia,sustained metabolic acidosis,blood-borne infections,local cold injury or bleeding.Infants in passive cooling group had a relatively wide range of rectal temperature fluctuations[average (33.47-0.71) ℃] and infants in active cooling group had a relatively narrow range of rectal temperature fluctuations[average (33.66 ± 0.29) ℃],but there was no statistically significant difference in their mean rectal temperature(t =1.941,P =0.055).One patient died in active cooling group,but there were no significant differences in suckling age,length of hospital stay,neonatal behavioral neurological assessment score,abnormal cranial ultrasound and MRI between the survivors of the two groups(all P ＞0.05).Conclusions In NICU,environmental temperature is relatively stable,passive cooling for asphyxiated newborns appears to be feasible for maintenance of hypothermia with a lower risk of adverse reactions.

Objective To detect the levels of 25-hydroxyvitamin D3 and analyse the related clinical factors in patients with chronic kidney disease (CKD).Methods Patients with CKD in our department from March 1st to July 1st were enrolled continuously.The level of 25-hydroxyvitamin D3 and intact parathyroid hormone(iPTH) were detected by electrochemiluminescence and immunochemiluminescent respectively.Serum calcium,phosphorus and albumin were measured by automatic biochemical instrument.Results 127 patients were selected and the average age was (60.9?15.3).The mean level of 25-hydroxyvitamin D3 was (12.06?6.41)?g/L.82.6% patients had vitamin D deficiency and 96.9% patients had vitamin D insufficiency.The level of 25-hydroxyvitamin had no statistics difference D3 between stage 1,2 and 3 CKD patients but was much hihger than that of stage 4 and non-haemodialysis stage 5 patients.The level of 25-hydroxyvitamin D3 was not related to serum calcium,phosphorus and iPTH,while positively related to albumin and eGFR and negatively related to serum creatinine and total cholesterol.Conclusion Vitamin D deficiency and insufficiency are frequent in CKD patients and deteriorate with the progress of kidney function impairment.The level of 25-hydroxyvitamin D3 is not related to the traditional CKD-MBD index such as serum calcium,phosphorus and iPTH.
