Ureteral cancer associated with dermatomyositis

Dermatomyositis is a rare inflammatory myopathy that has characteristic cutaneous lesions. Although many malignancies are associated with dermatomyositis, urogenital malignancies have rarely been reported to be associated with dermatomyositis. We report here on the first case of ureteral cancer associated with dermatomyositis. A 42-year-old man presented to us with a skin rash. A clinical diagnosis of dermatomyositis was made due to the skin lesions, muscle weakness, arthralgia, the increased erythrocyte sedimentation rate and the increased creatine kinase level. The patient revealed microscopic hematuria and abnormal urine cytology during the investigation for the underlying malignancy. Retrograde pyelography demonstrated a suspicious lesion in the right mid-ureter, and the ureteroscopic biopsy revealed the urothelial carcinoma. Although an operation was recommended, the patient died of pneumonia associated with his interstitial lung disease, which is one of the poor prognostic indicators of dermatomyositis.     

超声心动图对62例房间隔缺损封堵术后心功能变化的评价

目的：应用超声心动图评价房间隔缺损(ASD)封堵术前后左、右心室功能的变化。方法：对62例成功施行经皮穿刺ASD封堵术的患者进行研究。所有患者在术前、术后1周及1个月分别进行超声心动图检查．观察心脏大小及功能的改变。结果：ASD封堵术后，左室舒张末期前后径、左室舒张末期容积、左室每搏量及左室射血分数增大，而左室收缩末期容积未见明显改变；右室舒张末期前后径、右室舒张末期容积、右室收缩末期容积、右室每搏量、右室射血分数及右室心肌工作指数均减小。结论：经皮穿刺ASD封堵治疗既可减轻右室容量负荷，改善右室功能，也可改善左室的收缩功能：超声心动图对ASD封堵前后心脏血流动力学评价及疗效的观察起了重要的作用。

Urinary 17α-hydroxyprogesterone in management of 21 -hydroxylase deficiency

Objectives: The study was designed to assess the reliability of measurement of 24-hour urinary 17α-hydroxyprogesterone (17-OHP) by radio-immunoassay (RIA) as an alternative biochemical assessment for monitoring the treatment of congenital adrenal hyperplasia (CAH) due to 21 -hydroxylase deficiency (21 -OHD) and to assess the need for sample purification by column chromatography to improve assay specificity.
Methodology: Morning serum 17-OHP was measured using RIA and 24-hour urinary pregnanetriol using gas chromatography. Twenty-four-hour urinary 17-OHP was measured in samples from 17 prepubertal patients with CAH due to 21 -OHD, and 20 normal prepubertal children as controls. In 24 urine samples, RIA of 17-OHP was performed with and without column chromatography.
Results: There was a good correlation between 24-hour urinary 17-OHP and 24-hour urinary pregnanetriol (r = 0.962, P <0.01) and between 24-hour urinary 17-OHP and morning serum 17-OHP ( r = 0.955, P <0.01). There was no significant difference in the RIA of the urine samples with and without purification by column chromatography.
Conclusions: The measurement of 24-hour urinary 17-OHP is a reliable alternative for the biochemical monitoring of 21-OHD, and RIA specificity is unaffected by omission of column chromatography.

Induction of APOBEC3G in human hepatoma cells by interferon-α stimulation

To clarify the role of APOBEC3G (A3G) in cellular defense against hepatitis B virus ( HBV), the expression of A3G in normal human liver and the regulation of the A3G expression in hep-atoma cell line (HuH-7) were investigated. Expression level of APOBEC3s mRNA in human liver was determined by RT-PCR. HuH-7 and HepG2 cells were treated with various concentrations of IFN-α(0 U/ml, 100 U/ml, 500 U/ml, 1000 U/ml)for 12 h. The mRNA levels were measured by a quantitative RT-PCR, the results were normalized relative to the specimens without IFN-αstimulation. Total protein of HuH-7 cells treated with various concentrations of IFN-αfor 48 h was subjected to Western blot analysis. For reporter gene assay, HuH-7 cells were transfected with the reporter plasmids containing IRF-E sites and its mutants with different lengths. Then the cells were treated with or without 1200 U/ml IFN-a for additional 12 h (1000 U/ml) after 24 h of transfection, and the cell lysate was prepared and assayed for luciferase activity. It was found that normal human liver expressed the mRNA of A3G. A3G mRNA expression in HuH-7 and HepG2 cells were up-regulated by IFN-αstimulation in a dose-depen-dent manner. Western blot analysis indicated that A3G protein expression was also enhanced by IFN-αstimulation. Sequence analysis showed the existence of putative sites of IFN regulatory factor element (IRF-E) in 5' region of A3G gene upstream the initiation codon. IFN-αstimulation results in 6- to 8-fold increase in luciferase activity in cells transfected with the plasmid containing IRF-E sites of the 5' upstream sequences, whereas luciferase activity did not change in cells transfected with the plasmid containing mutant IRF-E sites or without IRF-E sites. As a conclusion, A3G are expressed in normal human liver. A3G expression was up-regulated by IFN-αstimulation in hepatoma cells and could be involved in host defense mechanisms against HBV. ERF-E site in 5' region of AP0BEC3G gene upstream the initiation codon plays an important role in this process.
