Objective:To explore whether metoprolol administration before emergency percutaneous coronary inter‐vention (PCI) can reduce incidence rate of reperfusion arrhythmia (RA) or not .Methods :According to random number table ,a total of 80 patients with acute anterior wall myocardial infarction (age< 75 years ,baseline heart rate >70 beats/min ,no PR interval prolongation ) were randomly and equally divided into routine treatment group (didn't receive metoprolol tartrate tablet before emergency PCI ) and metoprolol group (received metoprolol tartrate tablet 25 mg before emergency PCI ) .Incidence rate of RA after PCI was compared between two groups .Results:In metoprolol group ,a total of 32 cases received PCI and eight cases received percutaneous transluminal coronary angioplasty (PTCA);in routine treatment group ,a total of 35 case received PCI and five cases received PTCA ,suc‐cess rates of both groups were 100% .In metoprolol group , RA occurred in 4 cases ,including one case with ventric‐ular fibrillation (VF);in routine treatment group , RA occurred in 15 cases ,including four cases with VF .Inci‐dence rate of RA after emergency PCI in metoprolol group was significantly lower than that of routine treatment group (10.0% vs .37.5% ,P=0.032) .Conclusion:Metoprolol administration before emergency PCI can reduce in‐cidence rate of reperfusion arrhythmia in patients with acute myocardial infarction .

In recent years,there are many studies have reported that a small pupil syndrome appeared during routine phacoemulsification in patients with current or previous use of alpha-1 adrenergic receptor antagonists,with these clinical manifestations:an iris that appears floppy as it billows during normal irrigation and aspiration in the anterior chamber,a tendency for the iris to prolapse and progressive intraoperative miosis during surgery,which called intraoperative floppy iris syndrome This article mainly reviews the mobidity,pathogenesis,clinical features,complications,prophylaxis and treatment of the intraoperative floppy iris syndrome.

Newer retinal imaging technologies help us in understanding the pathogenesis of many retinal pathologies,such as diabetic retinopathy,age related macular degeneration,glaucoma and uveitis.Early detection of these retinal diseases can prevent the onset of progressive vision loss,and aid in the development of new treatment options.Retinal functional imager (RFI) is an unique and noninvasive functional imaging system.Unlike most of the available newer retinal imaging tools,the RFI not only shows retinal structural changes,but can directly monitor functional changes and measure hemodynamic parameters,such as retinal bloodflow velocity,oximetric state,etc.This article reviews the utility progress of RFI in various retinal diseases.

Objective To study the effects of obstructive sleep apneas on endothelial function and autonomic modulation. Methods From June 2009 to June 2011, male patients with obstructive sleep apnea hypopnea syndrome (OSAHS) were consecutively enrolled in this study. Patients with an apnea/hypopnea index (AHI) of greater than 15 and without previous treatment for OSAHS were included as Group OSAHS and obese subjects with an AHI of less than 5 were included as non-OSAHS controls (Group Control). Electrocardiography and beat-to-beat blood pressure were continuously recorded from the radial artery by applanation tonometry which was synchronized with polysomnography recording. Endothelial function was measured by arterial augmentation index (AAI). Spectral analysis of heart rate variability (HRV) and blood pressure variability (BPV) were computed for cardiac parasympathetic modulation (high frequency power, HF); sympathetic modulation (low frequency power, LF), sympathovagal balance (LF/HF power of R-R variability, LF/HF) and BPV sympathetic modulation (BPV LF) in normalized units [total power of the components/(total power-very LF power)×100]. Results Finally, 27 moderate-severe OSAHS patients and 22 non-OSAHS obese controls were recruited in the Group OSAHS and Group Control, respectively. In Group OSAHS, the age was 43.3±9.3 year-old, body mass index (BMI) was 36.8±8.7 kg/m2; in Group Control, the age was 42.9±8.6 year-old, BMI was 34.4±7.9 kg/m2; there were no significant differences in age and BMI between the Group OSAHS and Group Control (all P>0.05). The baseline AAI (12.5%±2.2% vs. 8.2%±2.1%) and BPV LF (68.3%±13.5% vs. 61.1%±11.7%) of the Group OSAHS were significantly higher than those of the Group Control (all P<0.05). And after overnight sleep, systolic BP (143.7±14.2 vs. 132.8±13.3 mm Hg), diastolic BP (87.7±7.7 vs. 78.6±5.5 mm Hg), HRV LF (69.7%±14.4% vs. 64.3%±12.1%), HRV LF/HF (3.7±2.0 vs. 2.3±1.3) and BPV LF (77.8%±15.6% vs. 68.3%±13.5%) of the Group OSAHS were significantly increased (all P<0.001), while HRV HF was significantly decreased (21.1%±9.3% vs. 27.5%±10.3%, P<0.05) from baseline.

BACKGROUND:Pelvic fractures are mostly caused by high energy trauma. With the development of imaging techniques and in-depth study of the anatomical structure of the pelvis and biomechanics, internal fixation and external fixation materials are gradual y being used in the repair of pelvic fracture. OBJECTIVE:To summarize features and applications of external fixation stent material, percutaneous screw fixation, percutaneous sacral iliac screw material for internal fixation and intramedul ary tensile screw material for internal fixation after pelvic fracture. METHODS:We retrieved Wanfang Database and PubMed for studies on the application of internal fixation material and external fixation material in pelvic fracture from 1994 to 2015. Al data were analyzed and summarized. RESULTS AND CONCLUSION:Application of pelvic external fixation materials contributed to the stability of early pelvic fractures, showed smal injury, could increase the reliability of fixation. However, the biomechanical stability of external fixation materials was lower than other internal fixation, could only be used for the early temporary fixation of unstable pelvic fractures in particular cases. Internal fixation materials can achieve anatomical reduction, accorded with the requirements of the physical mechanics of the pelvis, improve the stability of the pelvis, and have become the first choice for repair of unstable pelvic fractures. Currently used methods are percutaneous hol ow screw fixation, percutaneous fixation of the sacral iliac screw, and intramedul ary lag screw fixation. The combination of external fixation and internal fixation can effectively restore the stability of the pelvic cavity. Therefore, we should consider the location, type and stability of the fracture to select the appropriate internal fixation and external fixation materials.
