Objective To investigate the relationship between stent thrombosis and obstructive sleep apnea-hypopnea syndrome (OSAHS) in patients after coronary artery stent implantation (CASI). Methods One hundred and seventeen patients were rolled after CASI, of which 29 suffering from OSAHS were enrolled into the research group, 88 patients without OSAHS were enrolled into the control group. The incidence rate of stent thrombosis between the above two groups was analyzed. Results Three patients suffered stent thrombosis in the research group, with the incidence rate of 10.3%,which was significantly higher than that in the control group, with the incidence rate of 1.10%(P = 0.047). Conclusions After CASI, patients with OSAHS had higher risk of stent thrombosis compared with patients without OSAHS. OSHAS should be considered as a risk factor for stent thrombosis.

Objective To investigate the clinical value of modified BI?RADS classification by using the coronal plane of automatic breast volume scaner. Methods The total of 201 BI?RADS 3~5 classification of breast masses were retrospectively analyzed. All masses underwent conventional ultrasound and ABVS examination. Using BI? RADS classification standard terms to describe various information of breast masses, and record the coronal image of the masses on the complete interface echo, convergence sign, angle, burr, which classified BI?RADS ultimately. Results The coronal plane of convergence sign, complete interface echo, angulation and burr were significantly different between benign and malignant tumors (P<0.0001). The sensitivity of ABVS convergent sign in diagnosing breast malignant tumors was 68.2%, specificity was 93.4% and accuracy was 82%. The conventional ultrasound combined with the coronal feature of ABVS modified by BI?RADS classification showed that 3 kinds of malignant rate reduced from 8.5%to 3.2%. The rate of malignant 4a decreased from 25.2%to 12.1%and the rate of malignant 5 increased from 94.2% to 98%. Conclusion The convergence sign of ABVS can be used as a significant independent predictor of breast malignant tumors;ultrasound combined with ABVS is helpful to improve the accuracy of ultrasound BI?RADS classification.

Objective To observe the clinical efficacy of modified Sanzi Yangqin Decoction for the treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods Totally 80 cases of OSAHS patients were randomly divided into treatment group and control group, with 40 cases in each group. Both groups received intervention of diet and life. The control group was given vitamin C, 100 mg each time, 3 times a day orally. Treatment group was given modified Sanzi Yangqin Decoction, 1 dosage per day, twice a day, orally, for 14 d. The scores of TCM symptoms, sleep apnea (AHI), lowest oxygen saturation (LSaO2) and longest apnea were observed before and after treatment. Results The overall effective rate of TCM syndrome was 90% (36/40) in the treatment group and 65% (26/40) in the control group, with statistical significance (P<0.05). Compared with before treatment, there was statistical significance in the scores of TCM symptoms, AHI, LSaO2, and longest apnea (P<0.05,P<0.01). After the treatment, compared with the control group, there was statistical significance in the scores of TCM symptoms, AHI, and LSaO2 in the treatment group (P<0.05,P<0.01). Conclusion Modified Sanzi Yangqin Decoction can effectively treat OSAHS and improve the life quality of patients.

Objective To determine the baseline echocardiographic characteristics and the time course and degree of recovery of left ventricular (LV) systolic dysfunction in patients with tachycardia-induced cardiomyopathy ( TCM ) . Methods Seven hundred and fifteen patients received radiofrequency cather ablation ( RFCA ) for tachycardiarrhymias from July 2010 to July 2013 were screened in this study. Only 33 patients with reduced left ventricular ejection fraction (LVEF) (LVEF<50% and improved≥15%) were diagnosed with tachycardia-induced cardiomyopathy and were included in the study. Patients with early improvement (over 25%increase in LVEF at 1-week follow-up compared to the baseline ) were enrolled in the improved group , and the rest patients were enrolled in the improved group. All Patients received transthoracic echocardiography for LV size and function detection at 1 week and at 3,6,12 months follow-up. Results The average baseline of the LV end-diastolic diameter, and the LVEF were (55 ± 10.7)mm and (38 ± 4.6)%, repectively. Early improvement ( over 25%increase in LVEF at 1-week follow-up compared to the baseline ) in the improved group was observed in 16 patients. Patients with early improvement had higher LVEF at 12-month follow-up compared to the patients without early improvement [(69.2± 4.2)% vs (58.1 ± 6.9)%, P < 0.001]. Conclusions RFCA is proved to be a relatively safe and effecient treatment method. Atrial fibrillation related to TCM , rhythm control is superior to the rate control. The early improvement in LVEF may potentially predict the complete reversibility of LV systolic dysfunction.
