Objective To observe the blood circulation compensation in the involved area of the liver following ligation of the third grade branches of hepatic artery and portal vein and bile duct enclosed in Glisson’s capsule. Methods Ligation of the third grade branches of these ducts was carried out in 7 pigs. Uptake of 99mTc-EHIDA in the liver was scanned with SPECT pre-and post-operatively. Liver angiography of hepatic artery and portal vein were taken at regular interval. Corrosion casts of these ducts were made with ABS following extirpation of the liver at the end of experiment. The histological specimens were examined with electronic microscope. Results Compensatory circulation occurred between involved and noninvolved part of the liver through the sinusoids in 30-60 minutes after ligation. In the 6 weeks following the procedure, there was also blood supply in the affected region of liver, and collateral developed through hepatic aterioles and capillaries. Conclusion Liver has an ability to establish compensatory blood supply on the condition of ischema in a local region of liver.
In the management of diabetic nephropathy patients with hemodialysis, diabetes link nurse (DLN) can realize the continuity of nursing management, simplify the communication between multiple disciplines, and play multiple roles such as relieving patients’ psychology, participating in scientific research and clinical management. In this paper, by introducing the origin and development status of DLN in foreign countries, and summarizing the function and clinical contribution of DLN in the management of diabetic nephropathy hemodialysis patients. This article combines the current development status of DLN in China, to arouse the attention of clinical nursing colleagues, and provide some reference for the management of diabetic nephropathy patients with hemodialysis and the training of DLN in China.
【摘要】 目的 比較生血寧片和多糖鐵復合物膠囊兩種口服鐵劑在治療維持性血液透析患者腎性貧血中的治療效果。 方法 2008年12月-2010年6月間選擇40例維持性血液透析貧血患者，隨機分為生血寧片組和多糖鐵復合物膠囊組，每組20例，觀察期為8周。分別檢測兩組患者用藥前及用藥后4、8周時血紅蛋白、紅細胞壓積、血清鐵蛋白、轉鐵蛋白飽和度等指標情況。同時兩組患者均使用基因重組人促紅細胞生成素，按100~120 U/（kg·周），分兩次皮下注射。 結果 治療前兩組指標無明顯差異，治療后兩組患者的血紅蛋白、紅細胞壓積、血清鐵蛋白以及轉鐵蛋白飽和度較治療前均顯著上升，且兩組患者升高的幅度相比，生血寧組升高的幅度更顯著。治療結束時，兩組患者不良反應方面的差異無統計學意義。 結論 兩種口服鐵劑均能有效地糾正血液透析患者的鐵缺乏及貧血狀況；生血寧片組的作用更顯著，且還具備降低患者促紅細胞生成素使用量的作用。【Abstract】 Objective To compare the effect of Shengxuening piece and capsule polysaccharide-iron complex on anemia in hemodialysis patients. Methods A total of 40 patients with anemia in maintenance hemodialysis treated between December 2008 and June 2010 were randomly divided into Shengxuening piece group and capsule polysaccharide-iron complex group; the patients were observed for 8 weeks. Hemoglobin (Hb), hematocrit (Hct), serum ferritin (SF), transferrin saturation (TSAT) and other indicators were detected before treatment four and eight weeks after the treatment. While patients were used recombinant human erythropoietin (EPO) according to 100-120 U/(kg·week), twice subcutaneous injection. Results Before treatment, there was no significant difference between the two groups. Hb, Hct, SF and TSAT increased significantly after treatment in both of the groups and specially in the Shengxuening piece group. After the treatment, the difference in the adverse reaction between the two groups was not significant. Conclusions Both oral iron can effectively correct the hemodialysis patients with iron deficiency and anemia. However, Shengxuening has more significant role and may reduce the use of erythropoietin in patients with hemodialysis.
The early detection, diagnosis and treatment of lung cancer are the key points to reduce mortality and improve the prognosis. Detecting tumor markers in blood is a minimally-invasive, cost-effective, easy to administer and approachable test. A microsatellite consists of a tract of tenderly repeated DNA motifs that range in length from two to five nucleotides. Microsatellite alterations (MA) have been described as two types: loss of heterozygosity (LOH) and microsatellite instability (MSI). MicroRNA (miRNA) is a noncoding RNA and protein involved in regulating gene expression in the transcription level. In recent years, some miRNA markers and microsatellite alterations show significant tumor association, tissue specific and stability. Therefore, we write this review to discuss the microsatellite alterations and microRNA in blood of lung cancer.
Objective To assess the possible causes of acute pancreatitis (AP) in long term peritoneal dialysis (PD) and hemodialysis (HD) patients, and to discuss the diagnosis and treatment of AP in this kind of patients. Methods The clinical data of 9 cases of AP in PD and HD patients who were admitted in the hospital during January 1993 and January 2000 were analysed retrospectively. Results The serum levels of amylase of all the 9 cases were over three and a half times of upper limit value of healthy subjects. B mode ultrasound and CT scan examinations were useful for diagnosis of AP. Eight patients recovered very well with conservative treatment, while one patient who was diagnosed as acute severe pancreatitis and complicated with shock died. Conclusion Long term PD and HD patients are predisposing to develop AP. Diagnosis of AP in these patients primarily depends on the detection of serum amylase. Dialysis treatment is indispensable for cure of AP.
Purpose
To discuss changes of macular choriocapillaris hemodynamics in AMD.
Methods
Eighty-six eyes of 86 patients underwent ICGA,including macular drusen in 15 eyes of 15 patients,exudative AMD in 52 eyes of 52 patients,atrophic AMD in 19 eyes of 19 patients,for the observation of macular choriocapillaris perfusion.
Results
Choriocapillaris filling phase (CFP) of exudative AMD was obviously longer than that of eyes with normal, atrophic AMD and drusen groups (P＜0.05). Forty eyes had local or extensive choroidal filling deficiency and prolongation, including 24 eyes of exudative AMD, 12 eyes of atrophic AMD,and 4 eyes of drusen group.
Conclusion
CFP of macula is prolonged and choriocapillaris perfusion is abnormal in AMD and macular drusen eyes.

fter fracture of femoral neck , the head is often encountered ayascular necrosis. It was not clearwhether the causes of the necrosis was due to injury of the artery or stagnation of venous return orboth. We had observed the hmeodynamics of the blood circulation of both fermoral head of both sides in 27 cases of subcapital fracture by E. C. T. (Emission Computerized Tomography). The resultsshowed that either old, fresh, or heal fractures showed stagnation of venous return. There wasoblite...
The origin of blood supply and the features of vascular distribution of the fascia lata was obeervedby the method of microsurgical anatomy.It was found that there were 4 sources of the blood supplyfor the fascia lata. The blood vessels in the anterior supperior femoral area were from the original partof the decp femoral artery,while in the inferior part,the arteriess were from the tributary of theperforating artery. The blood vessels in the poterior superior femoral area were from both t...
