Successful recanalization of chronic total occlusion of the superior mesenteric artery by transradial approach

It is a challenge to confirm chronic mesenteric ischemia (CMI) as a cause of gastrointestinal (Gl) symptoms such as postprandial epigastric bloating,anorexia,and debilitating weight loss.Endovascular intervention for CMI has been gaining popularity because of the high morbidity associated with surgical revascularization.However,in EVI for superior mesenteric artery (SMA) occlusion,the transfemoral approach is limited by difficulty in coaxial alignment of the guiding catheter,which leads to insufficient back-up support.Herein,we report on a 58-year-old male patient with chronic total occlusion of the SMA,which was successfully revascularized by endovascular intervention via the left radial artery.Transradial endovascutar therapy may be another treatment option for the treatment of CMI.     

Morphological and pathologic changes of experimental chronic atrophic gastritis （CAG） and the regulating mechanism of protein expression in rats

INTRODUCTION In 1998 gastrointestinal pathologists reached aconsensus on the definition of chronic atrophic gas- tritis (CAG), which was described as programmed loss of gastric gland and/or replacement by intestinal glands in gastric mucosa. CAG was recognized to be closely related with development of gastric cancer and listed as precancerous lesions in this meeting (Genta, 1998). According to Correa (1992)’s cascade of gas-tric carcinogenesis, gastric cancer was believed to develop fr…     

Serum gamma glutamyl transferase (γ-GT) activity in alcoholics with liver abscess and chronic alcoholics

Gamma Glutamyl Transferase (γ-GT) is a microsomal enzyme. Its activity in serum is assayed in alcoholics with liver abscess and alcoholics without liver abscess after screening by ultrasonography. The enzyme activity in serum is increased by 334% in the patients with liver abscess compared to normal control subjects (p<0.0001), and 172% when compared to patients with chronic alcoholism without liver abscess (p<0.0001). The enzyme activity was increased by 59.3% in the serum of patients without liver abscess compared to the normal control subjects (p<0.001). Measurement of γ-GT in serum appears to be a sensitive index in the diagnosis of alcoholics with liver abscess.     

赵嘏研究述评（1980—2005）

晚唐诗人赵嘏,20世纪80年代后学界始有关注。二十年多来,学界对其生平事迹、诗歌艺术、诗集整理等皆有论述,赵嘏研究取得一定进展。另外,对敦煌残卷本《读史编年诗》的关注,成为赵嘏研究的一个亮点。但赵嘏研究整体上处于零散状态,学界投入力量有限,论家较少,有待学者们进一步发掘探索。     

Motivations to Disclose Chronic Illness in the Workplace

Managing chronic illness is not just a healthcare issue but is also relevant to workplace communication and relationships. Workers with chronic conditions are faced with the decision of if and how they should disclose the chronic condition to their supervisors and co-workers. These decisions are laden with fears of stigma or other forms of discrimination that are commonly associated with invisible identities. This study used a qualitative questionnaire and thematic analysis techniques to reveal three reasons why workers chose to (or not to) reveal their chronic condition in the work environment: facilitate continued employment, enacting values, and explaining absence or condition. Viewing the results through social exchange theory showed that employees exchange (or do not exchange) personal information for workplace accommodations.     

复方甘草甜素(美能)注射液治疗慢性乙型肝炎临床疗效观察

[目的]观察复方甘草甜素(美能)对慢性乙型肝炎的治疗作用.[方法]将病人随机分为为两组,治疗组10例,用美能40 m l/d.iv.3周后改为口服美能片75 mg,每日3次.对照组1 0例,使用甘利欣150 mg/d,VD.3周后改为口服甘利欣100 mg,每日3次.[结果]治疗组治疗后症状缓解率75%;血清ALT水平由306.70±229.33 u/L降为105.00±86.11 u/L;血清AST水平由137.90±71.44 u/L降为64.30±34.93 u/L;血清SB水平由31.80±28.90 umol/L降为16.20±3.43 umol/L.对照组治疗后症状缓解率为66.7%;血清ALT水平由208.20±160.13 u/L降为77.20±65.92 u/L;血清AST水平由92.60±61.19 u/L降为51.20±31.38 u/L;血清SB水平由20.60±5.08 umol/L降为11.70±2.06 umol/L.[结论]复方甘草甜素(美能)的临床疗效与国内同类产品(甘利欣)相仿,具有较好的保肝、降酶作用,有一定的优势.     

Clinical features of chronic hepatitis B patients with YMDD mutation after lamivudine therapy
