ObjectiveTo evaluate the effects of combined bisoprolol and candesartan therapy on left ventricular hypertrophy and left heart function in in elderly patients with hypertension. MethodsFrom July 2011 to August 2012, 117 elderly inpatients or outpatients with hypertension in our hospital were randomly divided into trial group and control group. Patients in the control group received levamlodipine besylate and bisoprolol, and patients in the trial group received candesartan and bisoprolol. ResultsThere was no statistical difference between the two groups at baseline. Three months later, there was no obvious difference of the blood pressure levels between the two groups (P>0.05). The parameters of left ventricular hypertrophy and left heart function were improved at the end of follow-up in both the two groups, but the parameters of the trial group improved better than the control group (P<0.05). ConclusionIn the elderly patients with hypertension, the combined bisoprolol and candesartan or levamlodipine besylate and bisoprolol therapy can improve left ventricular hypertrophy and left heart function, and the results are better for the combination of bisoprolol and candesartan.
ObjectiveTo explore the effect of irbesartan on patients with senile hypertension complicated with paroxysmal atrial fibrillation. MethodsA total of 126 inpatients and outpatients over 60 years of age with senile hypertension complicated with paroxysmal atrial fibrillation treated in our hospital from July 2010 to August 2012 were randomized into the study group (n=63, treated with irbesartan) and the control group (n=63, treated with amlodipine besylate). Diuretics was added according to blood pressure of the patients. All the patients were followed up for 12 months. Blood pressure control situation, atrial fibrillation recurrence frequency and duration time, alteration of left atrial inner diameter were compared between the two groups. ResultsThe level of blood pressure in both groups after treatment was significantly decreased compared with baseline, and there was no statistically significant difference in the decrease of blood pressure after treatment between the two groups (P>0.05). Atrial fibrillation recurrence frequency in the study group was (5.28±1.14) times, which was significantly lower than that in the control group[(9.24±1.34) times] (P<0.01). The paroxysmal atrial fibrillation duration time in the study group was (14.3±4.8) hours, which was significantly lower than that in the control group[(21.3±4.9) hours] (P<0.01). After treatment, the left atrial inner diameter in the study group was significantly diminished compared with that before treatment (P<0.01). ConclusionFor patients with senile hypertension complicated with paroxysmal atrial fibrillation, irbesartan is effective to control blood pressure, decrease atrial fibrillation recurrence frequency and duration, and inhibit left atrioventricular remodeling.
目的 探讨血浆脑钠肽（BNP）及血清肌钙蛋白I（cTNI）含量改变在老年患者发生充血性心力衰竭时的临床意义。 方法 选择2010年7月－2012年8月住院的各种老年心脏病患者117例，根据纽约心功能分级分为4组（心功能Ⅰ级组、Ⅱ级组、Ⅲ级组、Ⅳ级组），分别检测血浆BNP、血清cTNI及心肌酶[肌酸磷酸激酶（CK）、肌酸磷酸激酶同工酶（CK-MB）]进行组间比较，同时与健康老年组进行对比。 结果 ① 老年慢性充血性心力衰竭各组（心功能Ⅱ～Ⅳ级）血浆BNP水平均高于健康对照组及心功能正常组（心功能Ⅰ级组）；且心功能Ⅳ级组BNP水平＞心功能Ⅲ级组＞心功能Ⅱ级组。各组之间比较差异有统计学意义，但心功能Ⅰ级组与健康对照组血浆BNP水平无明显差异。② 各组之间CK及CK-MB水平差异均无统计学意义。③ 充血性心力衰竭各组（心功能Ⅱ～Ⅳ级组血清cTNI水平均高于健康对照组及心功能正常组（心功能Ⅰ级组）；且心功能Ⅳ级组cTNI水平＞心功能Ⅲ级组＞心功能Ⅱ级组。各组之间比较差异有统计学意义，而心功能Ⅰ级组及健康对照组血清cTNI水平差异无统计学意义。 结论 血浆BNP水平及血清cTNI水平在老年患者发生心力衰竭时随心力衰竭程度加重而逐渐升高，两者均对慢性充血性心力衰竭的临床诊断具有重要参考意义。
Objective To introduce the research of cell transplantation for treating intervertebral disc degeneration. Methods The original articles in recent years about cell transplantation for treating intervertebral disc degeneration were extensively reviewed, and retrospective and comprehensive analysis was performed. Results Transplantation of intevertebraldisc-derived cells or BMSCs by pure cell transplantation or combined with collagen scaffold into intervertebral disc couldexpress nucleus pulposus-l ike phenotype. All the cells transplanted into intervertebral disc could increase extracellular matrix synthesis and rel ieve or even inhibit further intervertebral disc degeneration. Conclusion Cell transplantation for treating intervertebral disc degeneration may be a promising approach.
To investigate cl inical outcomes of percutaneous kyphoplasty with balloon in the treatment of severe osteoporotic thoracic vertebral compression fracture (SVCF). Methods From May 2006 to July 2007, percutaneous unilateral kyphoplasty with single balloon was performed in 7 vertebras of 6 SVCF patients, with 2 injured vertebras in 2 malesand 5 in 4 females, who were from 64 to 83 years old. The injured vertebras included 1 in T5, 2 in T8, 3 in T10 and 1 in T12 and the compression rates were 60% to 75% in 5 vertebras and gt; 75% in 2 vertebras. All the injured vertebras were old fractures and caused severe back pain, but without any neurotic symptoms and signs. The visual analogue scale (VAS) ranged from 6.5 to 9.0, 7.7 on average. The posterior vertebral walls were all intact in all patients under CT scan. The balloon was inset into the vertebra through pedicle of vertebral arch by percutaneous puncture under the guidance of C-type arm X-ray unit. The balloon was then extended to restore the vertebral body which was filled with bone cement later. The average volume of cement required was 3.5 mL (2.6 to 4.4 mL). Results The pain was alleviated or completely rel ieved after the operation. The mean vertebral body height restoration was 9.7% ±1.4% on the anterior border. Two cement leakages were found on X-ray. One month after the treatment, the VAS was from 0 to 2.45, 1.32 on average, and there was significant difference compared with preoperation (P lt; 0. 05). Three months after the treatment, the VAS was from 0 to 3, 2.13 on average, and there was no significant difference compared with 1 month after the treatment (P gt; 0.05). It was not found that the injured vertebras were compressed or deformed, and no new compressed fracture was found in consecutive vertebras. Conclusion Unilateral posterior-lateral puncture kyphoplasty with single balloon can rel ieve the pain and restore part of the vertebral height effectively with better outcomes.
【Abstract】ObjectiveTo investigate the diagnostic value of the enhancement patterns for characterizing various focal hepatic lesions （FHL）. MethodsForty-seven patients (50 lesions) were included into the study. The morphologic features and the dynamic enhancement patterns of FHL were observed in the early arterial phase, late arterial phase and portal venous phase.The degree of FHL enhancement was analyzed by calculating the contrasttonoise ratio. Results70％ of the HCCs presented “fast-filling and rapid-washout” feature; 67％ of the cholangiocarcinomas showed slight enhancement in arterial phase, and 33.3％ had delayed enhancement on portal venous phase; All hemangiomas presented peripheral nodular enhancement in arterial phase, which then demonstrating centropedal “push-on” enhancement in portal venous phase; Hepatic abscesses mainly presented a slightly enhanced rim around the lesion with fibrous septa inside and an edematous zone outside. ConclusionThe enhancement pattern and the dynamic evolution of FHL enhancement had a great diagnostic value for different FHL by using MRI 3D-VIBE sequence.
