Objective: To study the efficacy and safety of microscope assisted nasal transsphenoidal pituitary tumor resection. Methods: pituitary tumor patients in our hospital from March 2011 to May 2013 were enrolled and divided into observation group given microscope assisted nasal transsphenoidal pituitary tumor resection and control group given oral-nasal septum-sphenoid sinus pituitary tumor resection according to different operation mode. Then stress level, curative effect related index and complications were observed and compared with existing research. Results: (1) Adrenaline, noradrenaline, rennin, angiotensin Ⅱlevel and operation time, intraoperative bleeding volume, postoperative hospitalization time of observation group were lower than control group, cases of hormone levels return to normal and improve were more than control group, complication cases were less than control group. (2)compared with the existing research on nerve endoscopic surgery, operation time, intraoperative bleeding volume, postoperative hospitalization time and cases of hormone levels return to normal, improve and complications of observation group had no statistical difference. Conclusion:microscope assisted nasal transsphenoidal pituitary tumor resection is helpful to reduce surgery trauma, relieve stress condition and can achieve equal operation effect and complications.

Objective To investigate the clinical effect of basilic vein transposition arteriovenous fistula in hemodialysis patients.Methods NInety patients with maintenance hemodialysis received in the NO.180 Hospital of the Chinese People's Liberation Army from September 2011 to September 2012 were randomly divided into two groups,and each group of 45 cases.Patients in the observation were given brachial-basilica transposition arteriovenous fistula,while patients in the control group received artificial vascular graft arteriovenous fistula.The fistula maturation time,dialysis blood flow,urea removal index (Kt/V),patency rates and complications were respectively recorded.Results Compared with control group,fistula maturation time,dialysis blood flow,Kt/V and complications rates in observation group were significantly higher((14.4±3.2)weeks vs.(16.1±2.7) weeks,(291.5±33.9) ml/min vs.(252.6±29.8) ml/min,(1.6±0.2) vs.(1.3±0.3);t =4.538,3.984,4.016;P＜ 0.05).Complications (ipsilateral upper limb swelling,thrombosis,venous ectasia and arteriovenous fistula stenosis) incidence were significantly lower than those of control group (2.2％vs.13.3％,2.2％ vs.11.1％,6.6％ vs.17.8％,11.1％ vs.24.4％;x2=5.463,4.972,5.017,3.968;P ＜0.05).Patency rates of observation group in 3 months,6 months,1 year and 2 years were also significantly higher than those of control group (97.8％ vs.93.3％,91.1％ vs.84.4％,88.9％ vs.75.6％,84.4％ vs.68.9％,x2 =5.315,4.238,7.024,5.913;P＜0.05).Conclusion Basilic vein transposition arteriovenous fistula is reliable and effective for hemodialysis patients.It can achieve adequate dialysis and less complications and It is worth of clinical application.

OBJECTIVETo investigate the morphology change of stomatognathic muscles after zygomatic plasty combined with mandibular angel plasty.

METHODS3D-CT facial soft tissue measurement was performed pre-operative and at 10 days,3 months post-operatively in 59 cases with prominent malar-complex and mandibular angle. The q test (Newman-Keuls method) was used to analyze the variance.

RESULTSThe cross sectional area of masseter muscle and medial pterygoid muscle were both increased at 10 days, reduced at 3 months post-operatively (P < 0.05). The masseter muscle and medial pterygoid muscle cross sectional areas were (4.73 +/- 0.21) cm2 and (3.24 +/- 0.21) cm2 at anterior nasal spine plane, respectively; the pterygoid muscle cross-sectional area was (1.37 +/- 0.35 ) cm2 at the root of coronoid process plane, showing significant difference, when comparing with those before operation (P < 0.05). Lateral pterygoid muscle and temporal muscle had no statistical difference between the pre-and 10 days post-operatively(P > 0.05), however, the temporal muscle was reduced while the lateral pterygoid muscle was increased at 3 months post-operatively. The temporal muscle cross-sectional area was(2.35 + 0.25) cm2 at coronoid process plane; the temporal muscle and lateral pterygoid muscle cross-sectional areas were (1.00 +/- 0.16) cm2 and (3.54 +/- 0.61) cm2 at the root of coronoid process plane, which were significantly different from those before operation (P < 0.05 ).

CONCLUSIONSBecause of osteotomy, muscles attached position are changed in the short term after zygomatic plasty combined with mandibular angel plasty. Masseter muscle and medial pterygoid muscle are inevitably injuried during the operation. With the postoperative recovery, muscles have adaptive changes which reduced compared with those before operation after their reattachment. Zygomatic plasty can cause temporal muscle atrophy;while the lateral pterygoid muscle is rarely involved, the cross sectional area had no statistical difference between the pre- and 10 days post-operative, and the cross sectional area increase at 3 months post-operatively may be due to a compensational enlargement.

Objective To investigate the function of SD rats Schwann cells on the growth and differentiation of adipose-derived stem cells(ADSCs) when they are co-cultured in Transwell culture system. Methods The ADSCs harvested from SD rats were divided into 3 groups. Group A: ADSCs and Schwann cells were cultured in Transwell indirect co-culture system. Group B: ADSCs were induced by β-BME and BHA. Group C: a contrast group. The morphology of ADSCs was observed and immunohistology was pedormed. Results ADSCs of group A and group B were partly differentiated to the cells which had long neurite,and had a positive result in the NF staining, but negative in the GFAP staining. Group A shows no great difference in neurite length compared with group B(P < 0.05), and no great difference in cell quantity compared with group C (P < 0.05). Conclusion Schwann cells of SD rat have a growth supportive and neuronal differentiation inducing effect on ADSCs.

Objective:To evaluate the precision of quantitative CT (QCT) in measuring fat content of goose liver and to explore the influence of tube voltage on liver fat measurement.Methods:From January to March 2017, 22 Landes geese were selected to establish fatty liver models with overfeeding. The QCT was performed under 2 different tube voltages, 80 and 120 kV. In addition to the voltage, the other scanning parameters were the same. Three ROI were placed in the centre part of the left lobe, upper and lower half of the right lobe on the 3D reconstructed images. The volume percentage of goose liver fat (Fat% QCT) was calculated according to the formula provided by Mindways. Immediately after the QCT examinations, each goose was dissected, and the whole liver was removed. Then samples were taken in the corresponding areas of the ROI by QCT. The fat (triglyceride) content of the samples was measured by the biochemical extraction method. The Spearman correlation tests were used to determine the correlation between the QCT measurements of 80 kV and 120 kV groups and the results of biochemical extraction method. The Wilcoxon signed-rank test was performed to compare Fat% QCT between 80 kV and 120 kV groups. Bland-Altman plots were used to assess agreement between the two groups′ measurements. Results:The Fat% QCT of both 80 kV and 120 kV group positively correlated highly with biochemical extraction ( r s=0.936, P<0.001, r s=0.927, P<0.001) respectively. No statistically significant difference of Fat% QCT was detected between 80 kV and 120 kV group ( Z=-0.141, P=0.888). Bland-Altman analysis showed a small difference of Fat% QCT between the 80 kV and 120 kV group, in which mean values were 0.20%. Conclusions:Using biochemical extracted triglyceride as the reference, under the conditions of low-dose 80 kV and standard 120 kV tube voltages, QCT measurement of fat content is accurate and reliable in goose liver.
