0.05).Conclusions:Facial nerve excited threshold detection was a simple and effective method of conjecturing TCM syndrome and severity and prognosis of facial paralysis patients.

Objective To observe the localization and expression of hepatocyte growth factor(HGF),c-Met and Caspase-3 in pulmonary arterioles during the formation process of pulmonary arterial hypertension(PAH) induced by left to right shunt in rats,and explore the effect of HGF and c-Met in the formative process of PAH.Methods Eighty male SD rats(aged 4-5 weeks) were randomly divided into control group and shunt group(40 each).Rats in shunt group underwent right common carotid artery-external jugular vein shunt with cannulation to reproduce PAH model of left to right shunt,and animals in control group only received sham operation.Pulmonary hemodynamic and pathologic examination were performed 4,8,12 and 16 weeks after operation in both groups,while the expression of HGF,c-Met and Caspase-3 proteins in pulmonary arterioles were determined by immunohistochemisty at the above time points.Results Pulmonary artery systolic pressure(PASP),mean pulmonary arterial pressure(mPAP) and the ratio of pulmonary to systemic circulation flow(Qp/Qs) were obviously increased in rats with A-V shunt compared with controls at all time points after operation(P

Objective To study the Value of low dose CT scanning with gas-contrasted and low window level in diagnosing gastro-colon lesions.Methods 126 cases suspected with gastro-colon lesions were randomly devided into two groups,group A(69 cases) were scanned with conventional water-contrast or non-contrast and conventional expose dose,and with conventional window level,group B(57 cases) were scanned with gas-contrasted and low expose dose,and using low window level.The images were evaluated by 2 experienced radiologists,the results including doctor's self-confidence and diagnostic accurate rate in both group A and group B were compared based on the endoscopic results.Results The diagnostic self-confidence of radiologists and the accurate rate in evaluating the lesions in group B were obviously superior to group A.Conclusion CT scanning of gastro-colon with gas-contrasted,low expose dose and low window level is markedly superior to conventional one.

To observe the effect of autologous stem cell transplantation in diabetic retinopathy.
●METHODS:Totally 58 cases (116 eyes) who underwent autologous stem cell transplantation were confirmed as no diabetic retinopathy (18 eyes), mild non-proliferative diabetic retinopathy (NPDR) (41 eyes), mid-level NPDR (51 eyes); severe NPDR (6 eyes) by ophthalmoscope directly or indirectly and fluorescence fundus angiography (FFA ). Follow - up was 6 - 12mo, the changes of retinopathy were observed.
●RESULTS: The total effective rate of vision and retinopathy was 84. 4%, 76. 7%. The results of severe NPDR was statistically worse than the other groups ( P <0. 05).
●CONCLUSlON: The stable blood glucose level and improved pancreatic function after autologous stem cell transplantation might be helpful in diabetic retinopathy, the long effects need to be researched further.

Objective To evaluate the value of pre-operative 99Tcm-MIBI SPECT/CT in patients with HPT by comparing with planar 99Tcm-MIBI and ultrasound imaging. Methods A total of 57 patients (9 males, 48 females; average age: (52.9±15.5) years) were enrolled into this retrospective study. They all underwent 99Tcm-MIBI planar scintigraphy, 99Tcm-MIBI SPECT/CT and ultrasound during March to October in 2016. All patients received parathyroidectomy and the surgical pathology was considered as the gold standard. The diagnostic efficiencies were compared using χ2 test. Results A total of 86 HPT lesions were confirmed, including 47 lesions in 46 PHPT patients and 39 lesions in 11 SHPT patients. The sensitivities of SPECT/CT, planar, ultrasound and combined imaging (planar plus ultrasound) were 87.21%(75/86), 69.77%(60/86), 65.12%(56/86) and 84.88%(73/86), respectively. The overall sensitivity of SPECT/CT was significantly higher than that of individual planar imaging and that of ultrasound (χ2 values: 4.691 and 7.818, both P<0.05), but similar to that of the combined imaging (χ2=0.044, P>0.05). No significant difference was observed among the specificities of all these modalities (χ2=2.219, P>0.05). For PHPT lesions, the sensitivities of SPECT/CT, planar imaging, combined imaging and ultrasound were 9574%(45/47), 93.62%(44/47), 97.87%(46/47) and 76.60%(36/47), respectively. No statistically significant difference was found in the sensitivity of the former 3 modalities (χ2=1.044, P>0.05), but the sensitivity of ultrasound was the lowest(χ2=16.223, P<0.05). For SHPT, the sensitivities of the corresponding 4 modalities were 76.92%(30/39), 41.03%(16/39), 51.28%(20/39) and 69.23%(27/39), respectively. SPECT/CT was significantly superior to planar imaging and ultrasound(χ2 values: 10.386 and 5.571, both P<0.05), but comparable to the combined imaging(χ2=0.586, P>0.05). Only SPECT/CT could accurately localize 5 ectopic HPT lesions. Conclusion Compared to planar imaging and ultrasound, SPECT/CT has higher sensitivity for SHPT patients, and could provide precise localization for ectopic lesions, thus facilitating patient planning for minimally invasive surgery.

AlM:To compare the effect of different incision in corneal astigmatism after phacoemulsification.
METHODS: Totally 88 cases ( 122 eyes ) with pure cataract were randomly divided into two groups. Forty cases (60 eyes) were clarity corneal incision in group A, and 48 cases ( 62 eyes ) were sclera tunnel incision in group B. Mean corneal astigmatism, surgically induced astigmatism ( SlA ) , uncorrected visual acuity ( UCVA ) and best correct vision acuity ( BCVA ) were observed in pre- and post-operation at 1d;1wk;1mo.
RESULTS: The mean astigmatism had statistically significant difference between two groups at 1d; 1wk;1mo after operation(P<0. 05). The SlA had statistically significant difference at 1d ( P<0. 05 ); The SlA had no statistically significant difference between two groups at 1mo after operation (P>0. 05). UCVA≥0. 5 and BCVA≥0. 8 had statistically significant difference at 1d; 1wk ( P<0. 05) . There had no statistically significant difference at 1mo after operation (P>0. 05).
CONCLUSlON: Phacoemulsification with scleral tunnel incision remove combined intraocular lens ( lOL ) implantation has small changes to corneal astigmatism. By selecting personalized corneal incision according to the corneal topography might be more beneficial.

AlM: To investigate and evaluate the prevalence of xerophthalmia among aerospace science and technology staff and its influencing factors for the eye health guidance.
METHODS: The staff underwent physical examination in our examination center from September 2013 to June 2014 were preliminary screened, and those patients with symptoms of dry eye were investigated with questionnaires and diagnosed by basic lacrimal secretion test ( Schirmer l ) , breakup time of tear film ( BUT ) test and fluorescein ( FL) staining test .
RESULTS: There were 606 complaints of dry eye symptoms of the 1 000 premiers, distributed in random (60. 6%), and 432 employees were diagnosed (43. 2%). The positive rate of dry eye was 71. 3%. The causes of xerophthalmia, besides of gender, age, also include a variety of factors such as air-conditioner, heating, video terminals, sleep time, etc.
CONCLUSlON: Dry eye, an epidemic disease, has a variety of symptoms and complex etiology, the main causes of aerospace science and technology staff with dry eye is working environment and some local factors. We can give appropriate health guidance according to the different factors. Meanwhile the relevant series of dry eye screening should also be taken as a routine examination in ophthalmic examination.
