目的:分析髋关节结核的DR平片及MRI表现。方法收集我院近年来经手术病理证实或经临床治疗观察确诊的15例髋关节结核患者,均行DR平片检查,其中6例行M RI检查。回顾性分析髋关节结核的平片及M RI表现。结果骨性髋关节结核2例,滑膜型髋关节结核3例,全髋关节结核10例。结论 D R平片是筛选病变最简单、最经济的主要手段;MRI能够发现早期微小病变的显示,特别是对关节滑膜、软骨、软骨下骨及关节囊的显示较DR平片及CT 更清晰,对病变的早期诊断及术前病灶部位和范围的显示具有重要的价值。  相似文献

目的探讨孟鲁司特钠对慢性阻塞性肺疾病急性加重期(AECOPD)患者血清白细胞介素-13(IL-13)、肿瘤坏死因子-α(TNF-α)水平及肺功能的影响。方法将100例AECOPD患者按入院的先后顺序分为研究组和对照组,每组50例。2组均采用常规治疗。在此基础上,研究组加用孟鲁司特钠片治疗。分别检测2组治疗前、治疗14d后血清IL-13、TNF-α水平及肺功能指标[肺活量(FVC)、最大呼气峰流速(PEF)、第1秒用力呼气容积(FEV1)和第1秒用力呼气容积占用力肺活量之比(FEV1/FVC)比值]的变化。结果与对照组比较,研究组治疗14d后血清IL-13、TNF-α水平均明显降低,FVC、PEF、FEV1及FEV1/FVC比值则均明显升高(均P<0.05)。结论孟鲁司特钠治疗AECOPD能够明显改善患者的肺功能,降低患者的体内炎症因子水平。 更多还原  相似文献

Objective To introduce inhaled inactivated-mycobacterium phlei on prevention and treatment of moderate bronchial asthma to observe the clinical effect. Method This study was a prospective and controlled study. The patients diagnosed with asthma in our out-patient from March 2009 to December 2010 were collected, who met the following conditions were included in the study: age≥ 14 years; met the criteria of moderate chronic persistent bronchial asthma in Global Initiative for Asthma (GINA) in 2008; suspended receiving systemic corticosteroids, Montelukast, ketotifen and other anti-inflammatory and anti-allergic drugs in one month; no significant respiratory tract infections; and other serious illnesses or abnormalities known.A total of 100 patients with asthma were selected, including 37 males and 63 females, age (32.11 ± 12.95 )years. The patients were randomly(random number) divided into two groups: A group(treatment group; 16males and 34 females, age 33.56 ± 14.23 years) and B group (control group; 21 males and 29 females,age 30.66 ± 11.50 years); 50 in each group. No significant difference was noted between the two groups on age and gender composition. The patients in A group were treated with inhaled inactivated-mycobacterium phlei F. U. 36 Injection 1.72 μg/mL × 2 that adding 3 mL normal saline, once a day for 5 days. The patients in B group were treated with salmeterol xinafoate and fluticasone propionate powder for inhalation (50/100 μg), twice daily for sustainable use. The patients in the two groups were observed for one month. During this course, the patients in the two groups could inhale the salbutamol sulphate aerosol as need to relieve symptoms. And the number of using was recorded. Pulmonary function test and asthma provocative test were carried out on the Day O, 6 and 31. ACT scores were measured before and after the treatment. Results On Day 6 and 31 after treatment, the negative conversion rates of asthma provocative test of the patients in A group were 82% and 78% respectively, B group were 84% and 90% respectively. Provocative test of the patients in the two groups were negative conversion significantly before and after treatment. There was no significant difference between the two groups by chi-square test (P > 0. 05 ). Completely random designed data was analyzed by analysis of variance. The analysis showed that the accumulated doses of methacholine of the patients in the two group increased significantly ( P < 0. 05 ), but no difference between the two groups.There was a improvement trend on forced expiratory volume in one second( FEV1 )of the patients in A group after treatment, but no difference. FEV1 of the patients in B group increased significantly higher ( P <0.05), which was significantly higher than A group on the 31th day (P <0. 05); Peak expiratory flow (PEF) of the patients in the two group increased significantly on Day 6 and 31 after treatment (P <0.05 ).On Day 31, B group was significantly higher than A group ( P < 0. 05 ); Scores of asthma control test (ACT)of the patients in the two group were significantly increased, and the number of using of salbutamol sulfate aerosol was significantly reduced (P <0.01 ). B group was obvious than group A (P <0.05 ). During treatment, there were only two adverse reaction cases of transient low fever; most obvious was on the third day.Conclusions Inhaled inactivated-mycobacterium phlei would inhibit the airway hyperresponsiveness of the patients with moderate bronchial asthma in short time, improve the symptoms, reduce the acute exacerbation, and reduce the use of rescue medication, which has the roles of prevention and treatment of moderate asthma in a certain period of time.  相似文献

目的:探讨改良下斜肌切断术治疗伴下斜肌功能亢进的 V 型斜视的疗效。方法对68例(106眼)伴下斜肌功能亢进的 V 型斜视行改良下斜肌切除联合水平直肌后退及(或)缩短术,术后观察评价下斜肌功能、眼位及双眼单视功能。结果术后100眼(94.3%)下斜肌功能亢进消失、6眼(5.6%)下斜肌亢进、无下斜肌功能不足者。术前水平斜视角平均64.5△,术后9.2△,术前垂直斜视角平均15.8△,术后随访为2.2△,平均降低13.6△。术前7例(12.5%)有双眼单视功能,术后47例(73.5%)有不同程度的双眼单视功能。结论改良下斜肌切断术是伴下斜肌功能亢进的 V 型斜视的有效术式。  相似文献

目的检测有危险因素者BRCA1第11外显子的突变率。方法38例有危险因素者,年龄29-71岁,有乳腺癌及卵巢癌家族史18例,其中3例本人患乳腺癌;有其他恶性肿瘤家族史者17例;有良性病变者8例,其中1例本人患宫颈癌。25例无危险因素者为对照组。受检者抽取外周血进行DNA提取,经PCR扩增后测序,与NCBI基因库比对。结果1例乳腺良性病变伴宫颈癌者检出4个碱基的缺失突变。危险因素组与对照组另检出6个相同位点的突变,其中5个位点在危险因素组和对照组突变率分别为65.8%和36.0%,两组间存在显著差异(P〈0.05)。结论发生于性器官的恶性肿瘤可能有共同的突变位点,危险因素组突变率显著高于对照组,提示家族性乳腺癌可能与更常见的、低外显率基因变异的综合作用有关。  相似文献
