AlM: To compare the results of 4 methods for measuring angle of exodeviation in the three types of intermittent exotropia, including when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test.
METHODS: Prospective case series study. Sixty-five patients with intermittent exotropia between June 2013 and June 2014 were enrolled in the Department of Ophthalmology, Affiliated Hospital to Qingdao University, included 37 males and 28 females with average age ( 12. 5 ± 6. 2 ) years. All the patients were measured when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test. lntermittent exotropia was divided into basic type, convergence insufficiency type and divergence excess type, which was based on the different result of between the distance and near measurements. The One-way test was applied to analyze the four methods of measuring angle of exodeviation in the three types of intermittent exotropia. LSD - t test was applied to compare the differences between each two methods in each type.
RESULTS: The distance exodeviations tested with looking at indoor distance target of 6m, looking at indoor distance target of 30m , looking at outdoor far distance target, after 1h diagnostic occlusion test were basic type (45. 4 ± 21. 0, 55. 0 ± 15. 0, 64. 68 ± 17. 7, 68. 75 ± 16. 6PD), convergence insufficiency type (33. 3 ± 14. 0, 44. 9 ± 12. 9, 43. 6±11. 8, 54. 6±11. 2PD), divergence excess type (55. 6± 17.4, 66.3±18.8, 76.9±16.4, 78.1±15.6PD). There were obviously differences between each two methods in each type ( basic type F = 9. 649, P = 0. 00; convergence insufficiency type F=6. 886, P=0. 001; divergence excess type F = 7. 989, P = 0. 00 ). Compared with looking at indoor distance target of 30m, looking at outdoor far distance target ( basic type P=0. 044, divergence excess type P = 0. 048 ) and after 1h diagnostic occlusion test (basic type P=0. 04, divergence excess type P=0. 027) had the statistical difference in the basic type and divergence excess type, and there was no obviously difference between looking at outdoor far distance target and after 1h diagnostic occlusion test ( basic type P=0. 353, divergence excess type P=0. 815). Compared with the other three measurements, 1h diagnostic occlusion test can elicit larger angle of deviation in the convergence insufficiency type.
CONCLUSlON: Both measurement with looking at outdoor far distance target and after 1h diagnostic occlusion test can elicit the larger angle of deviation in the basic type and divergence excess type; The measurement with after 1 hour diagnostic occlusion test can elicit the larger angle of deviation in the convergence insufficiency type.

OBJECTIVETo study the influence of bone marrow mesenchymal stem cells (MSCs) transplantation on hypoxic pulmonary hypertension (HPH) in rats.

METHODSSD rats MSCs were separated, cultivated, identified and labeled by the green fluorescence protein (GFP) gene virus and transplanted in vitro. Healthy male SD rats were randomly divided into four groups: Normal control group (NC group) and HPH group (eight rats respectively), HPH+ MSCs transplantation group and HPH+ VEGF+ MSCs transplantation group (twenty-four respectively). The test employed atmospheric intermittent low oxygen method to establish the rat model of pulmonary hypertension and stem cells were transferred and transplanted. The rats' mean pulmonary artery pressure (mPAP) was observed; right ventricular hypertrophy index (RVHI) was calculated; the morphological change of lung small artery in various groups of rats was observed under the microscope; the distribution of lung small artery and adenovirus transfection fluorescently labeled MSCs was observed under a fluorescent microscope after 7, 14 and 28 days when stem cell was transplanted.

RESULTSFor NC group, the mPAP (mmHg) was 15.5 +/- 1.5 after twenty-eight days while the mPAPs for HPH , MSCs and MSCs+ VEGF were 26.1 +/- 1.9, 21.6 +/- 2.7 and 20.1 +/- 2.9 respectively which were apparently higher than that of NC group (P < 0.01) and compared with HPH group (P < 0.01), which declined clearly. There was no significant difference between MSCs and MSCs+ VEGF. After twenty-eight days, RVHI for NC group was 0.28 +/- 0.02 while the RVHI for HPH, MSCs and MSCs + VEGF were 0.43 +/- 0.07, 0.34 +/- 0.03 and 0.35 +/- 0.01 respectively which was apparently higher than that of NC group (P < 0.01) but which was clearly lower than that of MSCs and MSCs+ VEGF (P < 0.05) and there was no significant difference between MSCs and MSCs + VEGF. For HPH group, pulmonary arteriole wall became apparently thicker, the lumen became significantly narrow and nearly obstructed after twenty-eight days, the endothelial cells were incomplete; compared with HPH group, pulmonary arteriole wall of MSCs group became thin, the lumen was smooth and the completeness of endothelial cells was improved. Whereas for MSCs and MSCs + VEGF, these changes were not significantly clear.

CONCLUSIONAfter MSCs transplantation, mPAP and RVHI decline sharply and lung small artery remodeling is improved which partially reverses HPH process; there is no significant difference between VEGF together with MSCs transplantation group and pure MSCs.

Objective To observe the effect of fluoxetine on the single prolonged stress model which mimic the post-traumatic stress disorder (PTSD). Methods Rats receiving single prolonged stress (SPS) (2 h restraint + 20 min FST + anaesthesized to lose consciousness with ethylether) or not were given fluoxetine or tap water for 15 days. Elevated plus maze(EPM),open-field test(OF) and morris water maze(MWM) tests were used to evaluate rats' fear response to environment,high alertness,anxiety & depression behavior,and learning and memory ability. Results In open field test, group of fluoxetine(F1 (8895. 85 ± 599. 78) mm, (40. 23 ±4. 32) s;F2 (8654.07 ±866.05)mm,(41.57 ±4.34)s, P<0.05) showed significant increase in activity times and horizontal motion distance compared with group of SPS (4678.85 ±495.33)mm, (22.15 ±3.43)s, P<0.05). In EPM experiment,group of fluoxetine(F1 (32. 62 ± 4. 57)% , (17. 58 ± 3. 23)% ; F2 (39. 75 ± 4. 46)% , (19. 74 ± 4.44) %) showed significant increase in percentage of the open-arm into the maze and percentage of the open arm pause compared with group of SPS ((23.67 ±2. 87)% ,(12.46 ±2.55)% , P<0.05). In MWM experiment,the escape latency of the SPS group increased significantly in comparison to that in sham group (P<0.01) and fluoxetine group. Fluoxetine significantly reversed the SPS-induced decrease in time spent in the target quadrant (P< 0.05). Conclusion Added fluoxetine can obviously improve rats' fear response to environment ,high alertness ,anxiety & depression behavior as well as learning and memory ability.

Objective To observe the curative effect of captopril and metoprolol in the treatment of chronic Keshan disease (CKD). Methods One hundred and ninty-five patients with CKD chosen from Juxian, Wulian, Yishui, Pingyi, Sishui and Zoucheng in Shandong Province were randomly assigned to control group, captopril group and metoprolol group according to NYHA cardiac functional grading. All cases were given diuretics, digitalis and vasodilating agents as routine treatment. On this basis, captopril and metoprolol was administered in captopril group and metoprolol group respectively. After 12 months of follow-up visit, the causes of cardiac death, hospitalization status and the changes of heart size, electrocardiogram, blood pressure and heart rate were all observed. Results It was found that the mortality of captopril group and metoprolo] group was 4.76% (3/63), 5.00% (3/60) respectively, both lower than the control group 10.61%(7/66). But this difference had no statistically significance(P=0.39). Besides, the hospitalization days of each year in captopril group and metoprolol group was respectively (19.12± 20.35) and(18.86±21.52)days, much more reduced than in the control group[(21.45±21.74)days, q=3.17, 3.38, P<0.05]. The detection rate of cardiothoracic ratio decreased in captopril group and metoprolol group [45% (27/60) and 40.4% (23/57)] After treatment showed more pronounced amelioration than the control group [18.6% (11/59), χ2=9.51,6.59, all P<0.0125], still the detection rate of cardiomegaly and invariability had no significant difference among three groups (χ2=2.50,4.75, all P>0.05). The elimination coefficient of ectopic rhythm in metoprolol group [56.5% (13/23)] was pronounced higher than the control group and captopril group [23.8% (5/21), 22.7% (5/22)], but differences had no statistically significance(P=0.0358,0.0331, all P>0.0125). Significant differences were found in systolic blood pressure(SBP), diastolic blood pressure(DBP) and heart rate(HR) in three groups prior and post-treatment(F=47.51,44.23,80.66, all P<0.01). The interaction of therapy and treatment time had influence on SBP and HR (F=3.19,37.44, all P<0.05), but had no influence on DBP(F=2.21, P> 0.05). There was no difference in SBP, DBP or HR among three groups before treatment(F=0.28,0.57,1.80, all P>0.05). After treatment, SBP and DBP in captopril group, metoprolol group and the control group[(109.0±10.9), (112.2±12.8), (114.7±13.2)mm Hg, (69.3±7.2), (72.1±9.5), (73.3±9.3)mm Hg] were all lowered compared with pre-treatment[ (117.1±13.4), (119.0±14.4), (117.6±14.1)mm Hg and (74.2±10.2), (76.3±10.8), (75.4±11.1)mm Hg, t=4.79,4.47,2.08,5.12, 4.32,2.15, all P<0.05]. HR was reduced in metoprolol group, being [(66.2±7.7), (75.9±11.5)times/min] before and after treatment(t=10.81, P<0.01), while it remained unchanged in captopril group and control group[(70.6±8.0), (72.6±10.5) times/min and (71.9±10.4), (73.8± 12.2)times/min, t=1.77,1.74, all P>0.05]. After treatment, both SBP and DBP of captopril group were significantly lower than that in the control group (q=3.52,3.56, all P<0.05); HR was reduced in metoprolol group, lower than that in captopril group and control group(q=5.44,3.73, all P<0.01). Conclusions Having a tendency of depressing mortality, captopril and metoprolol can reverse or delay myocardial remodeling and reduce admission rate in a safe,reliable and economic way, and are worth to be widely used in the treatment of chronic Keshan disease.

Objective To study the expression and pathologic significance of CD147,cyclophilin A (CyPA)and cyclophilin B(CyPB)in psoriatic lesions.Methods Immunohistochemical method was ap- plied to detect the expression of CD147,CyPA and CyPB in skin specimens of 15 patients with psoriasis pustulosa(PP),20 patients with progressive psoriasis vulgaris(PPV),and 20 patients with inactive psori- asis vulgaris(IPV).Immunoreactivity intensity distribution index(IRIDI)was calculated to assess the expres- sion intensity of CD147,CyPA and CyPB.Results CD147,CyPA and CyPB were detected in all speci- mens.The IRIDI scores of CD147 and CyPA were significantly higher in keratinocytes of psoriatic lesions than in those of the control specimens(all P0.05).The IRIDI score of CyPB in T lymphocytes of PP lesions was significantly elevated than that in PPV lesions,which was in turn higher than that in IPV lesions(all P0.05).Conclusion CD147,CyPA and CyPB may play a role in the occurrence and development of psoriasis.

Objective To observe the expression change of phosphorylation glogyen synthase kinase 3β at Ser9 [p-GSK3β (Ser9)] and investigate whether GSK3β involved in the retinal ganglion cell (RGC) and optic nerve in rat ocular hypertension model.Methods Thirty health Sprague Dawley (SD) rats with normal intraocular pressure (IOP) were randomly divided into 3 groups(10 cases in each group):control group,2 weeks ocular hypertension(OHT) group and 4 weeks OHT group.The ocular hypertension model was established by using episcleral veins ligation and cauterization.5 eyes from each group were taken for frozen section at week 2 and week 4 after establishing ocular hypertension model.The number of RGC was counted with Nissl's staining.The expression and distribution of p-GSK3β (Ser9) in RGC and optic nerve were detected by immunofluorescence staining.The retinal sample of other 5 rats was harvested for detecting the expression of total glogyen synthase kinase 3 β (total GSK3β) and p-GSK3β (Ser9) by Western blot.Results There was no statistical difference in IOP before modeling among three groups (P =0.89),but there was statistical difference after modeling (P ＜0.01),compared with the control group,the increased rate of IOP in 2 weeks OHT group and 4 weeks OHT group were 59.13％ and 26.93％ (all P ＜ 0.05).The average RGC numbers of 2 weeks OHT group and 4 weeks OHT group were 120 ± 10 per eye and 86 ± 7 per eye,which were both less than the number 149 ± 12 per eye in control rats,there were statistical differences (all P ＜ 0.05).Furthermore,the number of RGC in 4 weeks OHT group was less than 2 weeks OHT group (P ＜0.01).The expression of p-GSK3 β (Ser9) in the retina and optic nerve were positive detected by immunofluorescence,and the intensity of p-GSK3β (Ser9) immunofluorescence staining in RGC and optic nerve of OHT rats were less than model control eyes.The amount of p-GSK3β (Ser9) in retina of 2 weeks OHT rats decreased 19.89％ compared with control group rats (P ＜ 0.05),and the amount of p-GSK3β (Ser9) in retina of 4 weeks OHT rats was significantly decreased 36.46％ compared with control group rats(all P ＜ 0.05).While the total GSK3β did not change(P ＞ 0.05).Conclusion The number of RGC and the expression of p-GSK3β (Ser9) in RGC and optic nerve of OHT rat eyes decreased significantly.The change expression of the p-GSK3β (Ser9) in the RGCs and optic nerve may be correlated with RGC neurodegeneration in glaucomatous disorders.

This study is to evaluate the effects of Shenmai injection on the temporal alterations of action potential (AP), early afterdepolarization (EAD) and delayed afterdepolarization (DAD) in papillary muscles. The action potentials were recorded by a glass electrode. APD at 90% repolarization (APD9 ) was measured, and spontaneous EAD and DAD were observed. The results show APD90 was significantly prolonged in model group compared with sham-operated group, whereas it was remained unchanged in Shenmai injec- tion treatment group and amiodarone group. The spontaneous EADs and DADs were frequently visible in model group. In conclusion, EAD, DAD and trigger activities increase gradually during pathological progression of rat cardiac hypertrophy, and Shenmai injection could improve the action potential change in rat cardiac hypertrophy.
