Crohn病的CT表现

目的探讨Crohn病的CT表现特点。方法回顾性分析经病理证实的18例Crohn病的CT征象，大多数病例采用螺旋CT或多层螺旋CT扫描。结果所有病例均有节段性肠壁增厚，CT增强有7例表现为肠壁均匀增厚，缺乏层次，同时肠壁强化不明显；有11例表现为黏膜增厚和分层形成“靶征”和“双环征”，肠壁厚度多在5～10mm；有9例表现为病变段肠管周围纤维脂肪成分增多，蜂窝织炎及肠周或肠系膜血管增多增粗。有5例CT首先考虑为其他疾病，1例考虑为闭攀性肠梗阻，1例首先考虑为肠结核，2例回盲部病变怀疑为癌，1例肠穿孔形成脓肿仅诊为化脓性感染。结论cT不但能准确显示Crohn病肠壁、肠系膜及周围结构的异常，增强CT还能区分活动性与非活动性病变，有助于临床采取合理而积极的治疗方案。     

Voiding patterns in men and women with lower urinary tract symptoms combined with nocturia

AIM: We evaluated differences between men and women with lower urinary tract symptoms (LUTS) combined with nocturia. METHODS: A total of 71 age-matched female-male pairs (median 58, range 20-81 years) who had moderate to severe LUTS and nocturia of more than once per night were enrolled in this study. RESULTS: In the younger group (<50 years), the International Prostate Symptom Score (I-PSS) results of the sexes were not significantly different. However, although total I-PSS results in the elderly group (> or =50 years) were not significantly different, quality of life index scores for women were higher (P = 0.002). On frequency-volume (FV) charts, mean total daytime voided volume (DVV) was significantly higher in younger men than in younger women (P = 0.017), but the mean nocturnal polyuria index (NPi) for women was higher than that for men (P = 0.047). However, maximum DVV (P = 0.009), mean DVV (P < 0.0001), total DVV (P < 0.0001), and mean nocturnal urine volume (P = 0.009) were significantly higher in elderly men than in elderly women. However, numbers of daytime voids were not different. CONCLUSION: Elderly women with LUTS have lower functional bladder capacities than elderly men, as suggested by their smaller mean voided volumes. However, no significant differences were observed between numbers of daytime voids, which was probably due to the smaller total daytime voided volumes of elderly women. In addition, although NPi for younger women and nocturnal urine volume for elderly men was higher, no other differences were observed in terms of other night-time parameters.     

Up-regulation of urinary UPIII mRNA levels in vesicoureteral reflux patients: Potential application as a screening test for vesicoureteral reflux

OBJECTIVES: Vesicoureteral reflux (VUR) is the most common congenital urinary tract anomaly. This disease can pose a major threat to the kidneys as twenty percent of patients with endstage renal disease are reported to have VUR. Although genetic studies for uroplakin III (UPIII) have been reported recently, no study has focused on UPIII gene expression in VUR patients. We describe here the up-regulation of UPIII mRNA in exfoliated urinary cells from primary VUR patients. METHODS: A real-time RT-PCR for UPIII mRNA was performed on exfoliated urothelial cells from 18 primary VUR and 38 control samples. UPIII mRNA copies were calculated for each sample. The statistical differences were assessed by the Mann-Whitney U test. Receiver operator characteristic curves were constructed for analysis of the diagnostic values. RESULTS: UPIII mRNA was found to be up-regulated to a greater extent in VUR than in control exfoliated urinary cells (mean +/- SE: 497.0 +/- 178.5 copies vs. 69.0 +/- 10.0 copies, respectively, P < 0.001). In evaluating the measurement of urinary UPIII mRNA as a screening test for VUR, the sensitivity was 77.8% and the specificity was 76.3% by the best diagnostic cutoff point. CONCLUSIONS: This is the first report demonstrating up-regulation of UPIII in mRNA levels in VUR patients. We submit that the quantitative measurement of urinary UPIII mRNA has a potential of developing into the first non-invasive screening test for VUR.     

Pituitary abscess in a pregnant woman.

Pituitary abscess is a rare and potentially lethal condition. Pituitary abscess in a pregnant woman has not been previously described. A 38-year-old pregnant woman (34 weeks gestation) with a pituitary mass complained of a progressive headache and sudden visual impairment. She was afebrile and had no inflammatory symptoms on admission. On MRI, the preoperative diagnosis was pituitary adenoma with sphenoid sinusitis. She underwent an uncomplicated transsphenoidal procedure for removal of the pituitary mass. The next day, labor commenced and a healthy preterm baby was delivered. Pathologic examination of the intrasellar mass showed polymorphonuclear cells, debris and no tumor cells. The sellar contents were cultured and Streptococcus viridans was grown. To our knowledge this is the first case of pituitary abscess reported during pregnancy. Although the patient was pregnant, the transsphenoidal approach was safe for the mother and the fetus. Surgical drainage and antibiotic therapy are required for the definitive treatment of this condition.     

骨性AngleⅡ类2分类错正畸治疗前后硬组织的变化

目的:采用直丝弓矫治器矫治成年患者骨性AngleⅡ类2分类错牙合,以研究正畸治疗前后牙、颌硬组织变化,评价正畸矫治效果。方法:本文选择了8例AngleⅡ类2分类错牙合成年患者,男3例,女5例,年龄19~27岁,平均23.6岁。拔除双侧上颌第一双尖牙,运用直丝弓矫治器进行治疗,拍摄治疗前后X线头颅定位侧位片,进行治疗前后的X线头影测量研究。结果:治疗后SNA角减小,ANB角减小,U1-SN角增大,L1-MP角增大,U1-L1角减小。上颌切牙牙根及上颌基骨明显腭向移动,减小了上颌骨突度;下颌切牙牙冠明显唇向倾斜,代偿了下颌骨后缩。结论:骨性AngleⅡ类2分类错牙合患者经过上颌拔牙矫治后,面形有所改善,取得了理想的矫治效果。     

LHRH-PE40识别结肠癌细胞膜表面蛋白的研究

目的探讨人结肠癌细胞系Lovo及人白血病细胞系Jurket细胞膜表面蛋白能否识别LHRH-PE40及是否存在竞争性抑制。方法将结肠癌细胞系Lovo及白血病细胞系Jurket制备成细胞膜,利用125I标记的LHRH-PE40与两种细胞膜进行放射性配基分析,与LHRH进行竞争结合分析。结果人结肠癌细胞系Lovo的结合竞争符合特异性配基-受体结合、竞争;而白血病细胞系Jurket未见配基-受体特异性结合。其中LHRH-PE40与Lovo细胞的亲和力:Kd=10·6±2·33nmol/L,容量Bmax=345±7·59pmol/mg。结论LHRH是结肠癌免疫治疗的有效靶点,LHRH-PE40对过度表达LHRH受体的结肠癌具有特异性杀伤作用,而对无LHRH表达的肿瘤无杀伤作用,对于药物的临床应用有着指导意义。

Direct endovascular thrombolytic therapy for dural sinus thrombosis: infusion of alteplase.

PURPOSETo evaluate the efficacy, safety, and results of direct thrombolytic therapy in intracranial dural sinus thrombosis by infusion of alteplase (recombinant tissue plasminogen activator).METHODSNine patients were treated during a 2-year period for intracranial dural sinus thrombosis. A microcatheter was placed directly into the thrombus in the dural sinus via the transfemoral route. Thrombolysis was initiated with a rapid injection of 10 mg of alteplase over 10 minutes, followed in 3 hours by a continuous infusion of 50 mg, then a continuous infusion at 5 mg per hour until complete thrombolysis or a total dose of 100 mg per day had been reached. Repeat thrombolysis was tried the following day if complete recanalization did not occur at 100 mg per day.RESULTSSuccessful recanalization with improvement of symptoms was achieved in all cases. Time required for complete thrombolysis was between 8 and 43 hours. The total dose of alteplase ranged from 50 to 300 mg. Complications of a small intrapelvic hemorrhage and oozing at a femoral puncture site occurred in separate cases, but were not related to the amount of infused alteplase. MR venograms obtained 1 to 4 weeks after the procedure showed no evidence of reocclusion of the dural sinuses.CONCLUSIONDirect fibrinolytic therapy with alteplase is safe, fast, and effective in treating dural sinus thrombosis. However, to prevent hemorrhagic complications, further studies are required to determine its optimal dose and proper rate of administration.
