AIM: To evaluate the effects and safety of intravitreal injection of triamcinolone acetonide ( TA ) or conbercept combined with macular laser grid photocoagulation in the treatment of macular edema secondary to retinal vein occlusion( RVO) . ·METHODS: Fifty cases ( 50 eyes ) with macular edema secondary to retinal vein occlusion were selected and assigned to 2 groups: intravitreal injection of TA or conbercept, and laser photocoagulation after 7d. Best corrected visual acuity ( BCVA ) , fundus examination, optical coherence tomography ( OCT ) and intraocular pressure ( IOP ) were examined before intravitreous injection and 14d, 1 and 3mo after laser, fundus fluorescein angiography(FFA) were examined 3mo after treatment. The postoperative results at each time point were compared with preoperative values. · RESULTS: Two kinds of treatment compared with preoperative, the BCVA all increased in various degrees. At 14d after intravitreous injection, 1 and 3mo after laser, the ratio of vision improved in TA group was 76%, 80%, 68%, conbercept group was 88%, 92%, 88%, BCVA of two groups in each period all had varying degrees of increase than preoperative. The best BCVA acquired at 1mo after treatment. The macular thickness after treatment was significantly lower than preoperative in two groups. At preoperative, 14d, 1 and 3mo after treatment, the macular thickness in TA group was 557. 5 ± 150. 9,301. 7±120. 1, 262. 7 ± 131. 2, 338. 1 ± 146. 5μm; the macular thickness in conbercept group was 569. 4 ± 135. 9, 282. 3 ± 133. 5, 259. 5 ± 116. 4, 307. 8 ± 122. 6μm. The macular thickness of the two groups were significantly different between preoperative and postoperative. · CONCLUSION: The combination of intravitreous injection of TA or conbercept with macular laser grid photocoagulation can be an effective method in the treatment of macular edema secondary to RVO, conbercept treatment is more effective and security.

ObjectiveTo observe the effects of XinShu parenteral solution (XSPS) on the activation of platelet, the activity of fibrinolysis system after intima denudation of rabbits.Methods20 male Japanese white rabbits (2.5±0.5)kg were randomly divided into the control group and XSPS group .The celiac arterial endothelium of all rabbits were denuded with balloon. Before the operation and 3d, 7d, after balloon denudation, vein blood samples were obtained from each group rabbits for measurement of α granule membrane protein of platelets(GMP-140), tissue-type plasminogen activator(t-PA) and plasminogen activator inhibitor-type Ⅰ(PAI-1).ResultsPlasma GMP-140 and PAI-1 activity obviously elevated after balloon injury, and there was a little elevation in plasma t-PA activity in control group. Activity of plasma GMP-140 in XSPS group remained bottom level after balloon injury, and there was a significant increase in plasma t-PA activity and a marked reduce in PAI-1 activity in XSPS group. There was a notable difference between group B and group C (P<0.05). ConclusionXSPS obviously inhibits platelet activation, and improves fibrinolysis activity after balloon injury.

ObjectiveTo analyze the relationship between result of hemorheology and non-pathological factors such as sex, age and life habit.Methods3483 healthy adults who had health examination were divided into different groups according to sex and age, and results of hemorheological test of them were analyzed and compared with reference values.ResultsAll hemorheological indexes of men were higher than that of women. The whole blood viscosity of female had an increasing trend along with the age increasing. However, the result of hemorheology of male showed that the index of the age of 30～49 was higher than the age of more than 50, and had a decreasing trend along with the age increasing after the age of 50. The index of high shear viscosity, low shear viscosity and hematocrit of both male and female were all higher than the reference values offered by apparatus.ConclusionEffect of non-pathological factors such as age, sex and life habit on index of hemorheology should be considered.

OBJECTIVETo analyze the correlation between olfactory bulb (OB) volume with depth of olfactory sulcus (OS) and olfactory function in patients with idiopathic rapid eye movement sleep behavior disorder (iRBD).

METHODSFifty patients with iRBD and fifty controls were assessed with polysomnography (PSG). The results of olfactory function T & T testing, OB volume and depth of OS assessed with magnetic resonance imaging (MRI) were compared. SPSS 11.0 software was used to analyze the data.

RESULTST & T olfactory testing revealed that iRBD patients had higher scores (3.1 ± 0.5) than those in controls (0.6 ± 0.1), and the difference was significant (t = 7.913, P < 0.05). Both men and women with iRBD were affected by the same extent of olfactory loss (t = 1.015, P > 0.05). OB volume of left side in iRBD patients was (33.75 ± 4.11) mm(3), right side was (34.57 ± 4.21) mm(3), average OB volume was (33.94 ± 4.15) mm(3); OB volume of left side in controls was (51.68 ± 7.71) mm(3), right side was (52.31 ± 7.77) mm(3), average OB volume was (51.94 ± 7.74) mm(3); OB volume were lower in iRBD patients as compared to controls (t value were 9.013, 8.889 and 8.923, all P < 0.01). OS depth study revealed no statistical difference between iRBD patients and controls (t value were 0.923, 0.897 and 0.904, all P > 0.05). Olfactory discriminate threshold was negatively correlated with OB volume in iRBD patients (r = -0.61, P < 0.05), but no correlated with depth of OS (r = -0.24, P > 0.05).

CONCLUSIONSThe OB volume was lower in iRBD patients as compared to controls. The depth of OS showed no significant changes in iRBD patients. The OB volume was correlated with olfactory function, while the depth of OS was no correlated with olfactory function.

The aim of the present study was to detect the transmission rate of ultrasonic low intensity pulsed ultrasound (LIPUS) through polytetrafluoroethylene (PTFE) membrane (Thickness: 0.01 mm) and Bio-Gide collagen membrane, and to provide the basis for the barrier membrane selection on the study of LIPUS combined with guided tissue regeneration (GTR). The ultrasonic (LIPUS, frequency 1.5 MHz, pulse width 200 micros, repetition rate 1.0 kHz) transmission coefficient of the two kinds of barrier membrane were detected respectively through setting ten groups from 10 to 100mW/cm2 every other 10 mW/cm2. We found in the study that the ultrasonic transmission coefficient through 0.01 mm PTFE membrane was 78.1% to 92.%, and the ultrasonic transmission coefficient through Bio-Gide collagen membrane was 43.9% to 55.8%. The ultrasonic transmission coefficient through PTFE membrane was obviously higher than that through Bio-Gide collagen membrane. The transmission coefficient of the same barrier membrane of the ultrasonic ion was statistically different under different powers (P < 0.05). The results showed that the ultrasonic transmittance rates through both the 0.01 mm PTFE membrane and Bio-Gide collagen membrane were relatively high. We should select barrier membranes based on different experimental needs, and exercise ultrasonic transmission coefficient experiments to ensure effective power.

Objective To analyze the clinical characters in old patients undergoing coronary artery bypass grafting (CABG). Methods The clinical data of 426 patients undergoing CABG from January 2000 to April 2009 in our hospital were retrospectively analyzed. One hundred eighteen patients were 70-82 years old (older group), 308 patients were 24-69 years old (younger group). The perioperative risk factors, surgical complication and outcomes between the two groups were compared.Results The older group had higher incidences of post-operative complications than younger group.Pre-operative risk factors included the female, chronic obstructive pulmonary disease, peripheral vessel disease, New york heart association(NYHA) class Ⅳ, unstable angina requiring intravenous nitrates until arrival in the anaesthetic room, left ventricular ejection fraction ＜30%. The older group showed higher incidences of postoperative severe complication, operative mortality, and more grafts and longer time in intensive care unit (ICU), and had lower incidents of valve disease and less use of left internal mammary artery [16 patients (13. 6%) vs. 152 patients (49.4%), all P＜0. 05].Conclusions The many CABG risk factors in China are different from those in the western countries.Although the higher incidents of postoperative severe complication and higher operative mortality are found in the older patients, the recovery period after operation isn't obviously prolonged. The operative outcomes are satisfactory.
