国产人α＿1型基因工程干扰素治疗慢性肝炎Ⅲ期临床试验

３９例慢性肝炎患者，其中乙型肝炎１２例，丙型肝炎２７例，接受人α＿１型基因工程干扰素治疗（ｒＨＩＦＮα＿１）。１０例丙型肝炎病人ｒＨＩＦＮα＿１每日肌注１×１０￣６Ｕ，连用９０天，１７例丙型肝炎病人和乙型肝炎ｒＨＩＦＮα＿１每日肌注３×１０￣６Ｕ，连用９０天。治疗后乙型肝炎组ＨＢｅＡｇ和ＨＢＶＤＮＡ的阴转率均为４１．６７％；丙型肝炎用１×１０￣６Ｕ／ｄ和３×１０￣６Ｕ／ｄ组ＨＣＶＲＮＡ阴转率分别为５０％和６４．７％，两个剂量组阴转率比较差异无显著性（Ｐ＞０．０５），治疗期间不良反应发生率较低，远期疗效尚待观察。     

胃癌患者胃液中5-羟色胺含量的检测及临床意义

本文应用高效液相色谱与荧光分光光度计联机法检测55例胃液内5-羟色胺的含量,共分为正常、溃疡病、萎缩性胃炎、胃癌等4个组。其结果正常组含量为48.70±49.3ng/ml,溃疡病组含量为76.26±127.06ng/ml,慢性萎缩性胃炎组含量为197.29±128.4ng/ml,胃癌组含量为191.80±124.2ng/ml。4组之间进行对比分析,正常组和溃疡病组之间差异不明显(P>0.05),而萎缩性胃炎和胃癌两组与前两组之间差异均显著(P<0.01),但萎缩性胃炎和胃癌之间未见差异(P>0.05)。这充分证明5-羟色胺(5-HT)在萎缩性胃炎和胃癌的胃液中含量是很高的。对于胃癌和慢性萎缩性胃炎的诊断及与其它慢性胃病的鉴别诊断中可能起到很重要的作用。     

Cardiovascular adaptations to transfusion/chelation therapy of homozygote sickle cell anemia

The effect of transfusion/chelation therapy on the cardiovascular adaptations to chronic anemia in pediatric and young adult patients with homozygous sickle cell disease is uncertain. This study compares left ventricular (LV) function indexes and thoracoabdominal aortic systolic and diastolic blood flow in nontransfused and transfused patients with homozygous sickle cell disease. The study population consisted of 29 nontransfused patients with homozygous sickle cell disease, ages 0.4 to 20.9 years (group 1) and 11 chronically transfused/chelated patients, ages 4.0 to 21.8 years (group 2). The mean total hemoglobin concentration in group 2 was 28% greater than that in group 1. The mean duration of transfusion/chelation therapy in group 2 was 3.7 years. The percent of predicted LV end-diastolic and end-systolic dimensions were significantly greater than the respective controls in both groups. There was no significant difference in percent of predicted LV end-diastolic dimension (group 1, 120 +/- 12%; group 2, 120 +/- 12%) or percent of predicted LV end-systolic dimension (group 1, 120 +/- 12%; group 2, 117 +/- 8) between the groups. The percent of LV shortening fraction was similar in study groups and control subjects. Aortic systolic blood flow (cc/min/m2) for group 1 (2,426 +/- 841) and 2 (2,374 +/- 1.004) were significantly greater than corresponding control values (1,683 +/- 442, 1,736 +/- 430, respectively). Aortic diastolic blood flow was significantly greater than corresponding control values for both group 1 (699 +/- 313 vs 488 +/- 212) and group 2 (1,080 +/- 607 vs 588 +/- 219).(ABSTRACT TRUNCATED AT 250 WORDS)

Fluconazole compared with ketoconazole for the treatment of Candida esophagitis in AIDS. A randomized trial.

OBJECTIVE: To determine the clinical and endoscopic response of candida esophagitis to antifungal therapy and to compare the two oral antifungal agents, fluconazole and ketoconazole. DESIGN: Multicenter, randomized, double-blind trial. SETTING: Fifteen U.S. centers including university, private practice, and county hospital settings. PATIENTS: A total of 169 patients with the acquired immunodeficiency syndrome (AIDS); odynophagia, dysphagia, or retrosternal pain; white esophageal plaques at endoscopy; and pseudohyphae on esophageal brushings or biopsies. INTERVENTION: Patients were randomly assigned to fluconazole (100 mg/d) or ketoconazole (200 mg/d). Doses were doubled at week 1 or 2 if no symptomatic improvement had occurred during the preceding week. Therapy was continued for 2 weeks after resolution of symptoms or for a maximum of 8 weeks. MEASUREMENTS: Patients were clinically evaluated weekly, and laboratory tests were done every 2 weeks. Endoscopy was repeated within 5 days after the end of therapy. RESULTS: A total of 143 patients were clinically evaluable (assessed within 7 days after therapy), and 129 patients were endoscopically evaluable (endoscopy repeated after therapy). Endoscopic cure occurred in 91% of patients treated with fluconazole and in 52% of those given ketoconazole for a difference of 39% (95% Cl, 24% to 52%; P less than 0.001). Esophageal symptoms resolved in 85% of fluconazole-treated patients and in 65% of ketoconazole-treated patients for a difference of 20% (Cl, 6% to 34%; P = 0.006). Intention-to-treat analyses also yielded statistically significant differences for the comparisons listed above. Side effects were minimal and comparable in the two groups; only one patient in each group had therapy discontinued for adverse effects that were possibly related to the study medications. CONCLUSIONS: Fluconazole is associated with significantly greater rates of endoscopic and clinical cure than ketoconazole in patients with AIDS and candida esophagitis. Both drugs appear to be safe and well tolerated.     

Adenocarcinoma in an isolated rectosigmoid bladder: case report.

We report a case of primary adenocarcinoma of the rectum 11 years after a radical operation and construction of an isolated rectosigmoid bladder for squamous cell carcinoma of the bladder. The isolated rectosigmoid bladder, which is not exposed to the fecal stream, may be associated with adenocarcinoma as in ureterosigmoidostomy.     

Treatment of ureter injuries after obstetric-gynecologic surgery]

The article presents an analysis of 21 patients with ureter injuries originated during obstetric-gynaecological operations treated in Urology Clinic in Medical Academy Poznań. Attention was particularly focused on prevention and fast diagnosis of injuries based on intra-operation examination usg, urography, and ascending pyelography. This fast diagnosis is of crucial importance for the cure.
