Objective To evaluate the safety and effectiveness of the treatment by selective β 1 receptor blockers on patients with chronic obstructive pulmonary disease (COPD).Methods Eighty cases of COPD Ⅲ (stable period) inpatient with or without coronary heart disease were collected in The Second People's Hospital of Shanghai from September 2012 to November 2013.The patients were randomly divided into testing group (Metoprolol treatment group) and control group (regular treatment group) with 40 cases for each group.Metoprolol group therapy based on the use of conventional metoprolol tablets,an initial dose of metoprolol 12.5 mg/d,titrated to the appropriate dose based on heart rate and tolerance of the morning resting heart rate of 55 to 60 times/min that reached the target dose of metoprolol continuous medication for 12 months.Blood gas analysis were recorded before and after treatment,pulmonary function,and 6 min walk test (6MWT) and were chronic lung disease Assessment Test (CAT) Rating.The control group was administrated regular treatment while the testing group added small dose of Metoprolol with titration to an appropriate dose on this basis.12 months in a row,and assessed the end stage.Results (1) After the application of selective β receptor blockers on testing group,no statistically significant difference (P＞0.05) in the values of FEV1 in anticipation value％ (testing group:(45.45 ± 4.68) ％ vs.(43.32 ± 4.84) ％;control group:(44.23 ± 4.68) ％ vs.(42.58 ±4.24)％),PaO2(testing group:(75.92± 10.78) mmHg vs.(74.86± 11.21) mmHg;control group:(70.23 ±6.45) mmHg vs.(72.36±7.28) mmHg) and PaCO2(testing group:(46.28±8.28) mmHg vs.(47.46±10.22) mmHg);control group:(44.54 ± 8.89) mmHg vs.(42.36 ± 7.45) mmHg) before and after treatment.But the 6MWD (testing group:(287 ± 23) m vs.(384± 34) m;control group:(284 ± 25) m vs.(295 ±21) m) and COPD appraisal test(CAT) (testing group:(21±7) score vs.(17±6) score);control group:(22 ±5) score vs.(20± 6) score) had improved significantly compared with that before treatment,with significant difference(t=4.903,4.784;P＜0.05).Conclusion Selective β receptor blockers have no effect on the airway resistance of COPD patients and reduction on pulmonary function.It can also increase the exercise tolerance and enhance the living quality for improving clinical prognosis.

Purpose To compare the pathological differences between cervical high-grade intraepithelial lesions (CHGIL) positive resection surgical margin after cold knife conization and total hysterectomy,and to explore how to take further clinical treatment measures.Methods The pathologic results of 74 patients with CHGIL positive surgical margin after cold knife conization and hysterectomy were analyzed retrospectively.Results There was a correlation between positive cervical incision margin and residual uterine lesion (P ＜ 0.01).Age,menopause status,gland involvement did not related to residual uterine lesions(P ＞ 0.05).There was significant correlation between the lesion-related quadrant and the residual rate of uterine lesion (P ＜ 0.01).Conclusion Cold knife conization and hysterectomy are safe and effective treatments for CHGIL.However,for the positive resection surgical margin after cold knife conization cases,hysterectomy should be carefully chosen and may choose conservative treatment or re-cone cutting.

Aim To investigate the role of mitochondrial aldehyde dehydrogenase 2 ( ALDH2) in the cardio-protection of ischemic postconditioning in isolated rat hearts. Methods Hearts isolated from male Sprague-Dawley rats were perfused on a langendorff apparatus and subjected to 30 min of regional ischemia( occlusion of left anterior descending artery) followed by 120 min reperfusion. Ischemic postconditioning was achieved by 6 cycles of 10 s reperfusion/10 s global ischemia starting at the beginning of reperfusion. The ventricular hemodynamic parameters and lactate dehydrogenase ( LDH) release during reperfusion were measured. The infarct size was measured by TTC staining method. The expressions of ALDH2,Bcl-2 and Bax at mRNA level of left anterior myocardium were detected by RT-PCR analysis. Results In contrast to ischemia and reperfusion,ischemic postconditioning improved the recovery of left ventricular developed pressure,rate pressure product during reperfusion,and reduced LDH release and infarct size. The expressions of ALDH2 mRNA level and the ratio of Bcl-2 /Bax were increased. Adminis-tration of ALDH2 antagonist cyanamide at the beginning of reperfusion attentuated the role of ischemic postconditioning. Conclusion Ischemic postconditioning plays a role in the cardioprotection partially through increasing mitochondrial ALDH2 mRNA expression.
