目的脑内有淀粉样蛋白沉积的患者,其PET显像所示纹状体内11C-匹兹堡化合物B（PiB）的摄取与阿尔茨海默病（AD）的分期有关。该研究分析纹状体和大脑皮质非可置换结合力（BPND）间的关系。方法回顾性分析73例PiB-PET显像结果为阳性的认知障碍患者,其中包括34例AD、26例轻度认知功能受损、2例额颞叶退行性改变、2例帕金森病（PD）、5例路易体痴呆和4例诊断不明患者。由PiB-PET动态显像获得各患者的BPND值,对纹状体和其他部位大脑皮质BPND值的关系进行基于体素的分析。结果纹状体与额叶前部大脑皮质BPND值之间有高度相关性,其中与左侧布罗德曼（Brodmann）11区相关性最高。几乎所有高BPND值的皮质区其BPND值均与纹状体BPND值相关,枕部皮质除外,其BPND值与纹状体BPND值相关性低。结论研究结果表明纹状体和与之有功能、解剖联系的大脑皮质间在淀粉样蛋白沉积上有正相关性。淀粉样蛋白在脑内的分布并不是随机的,而是有功能和解剖上的联系的。

AIM： To investigate the role of local colonic mucosal NK receptor-positive T （NKR＋ T） cells in the regulation of intestinal inflammation, we analyzed the population and function of these cells in ulcerative colitis （UC）. METHODS： Colonic mucosal tissues were obtained from colonoscopic biopsies of the descending colon from 96 patients with UC （51 endoscopically uninflamed, 45 inflamed） and 18 normal controls. Endoscopic appearance and histologic score at the biopsied site were determined by MaLts＇ classification. A single cell suspension was prepared from each biopsy by collagenase digestion. Two NKR^＋ T cell subsets, CD56^＋（CD56^＋CD3^＋） T cells and CD161＋（CD161^＋CD3^＋） T cells, were detected by flow cytometric analysis. Intracellular cytokine analysis for anti-inflammatory cytokine interleukin-10 （IL-10） was performed by in vitro stimulation with phorbol-myristateacetate （PMA） and ionomycin. RESULTS： CD56^＋ T cells and CD161^＋ T cells are present in the normal human colon and account for 6.7% and 21.3% of all mononuclear cells, respectively. The populations of both CD56＋ T cells and CD161^＋ T cells were decreased significantly in the inflamed mucosa of UC. In contrast, the frequency of conventional T cells （CD56 CD3^＋ cells and CD161CD3^＋ cells） was similar among the patient and control groups. The populations of NKR^＋ T cells were correlated inversely with the severity of inflammation, which was classified according to the endoscopic and histologic Marts＇ criteria. Interestingly, approximately 4% of mucosal NKR＋ T cells expressing IL-10 were detected by in vitro stimulation with PMA and ***： Selective reduction in the population of colonic mucosal NKR＋T cells may contribute to the development of intestinal inflammation in UC.

A retroperitoneal hemangioma is a rare disease. We report on the diagnosis and treatment of a retroperitoneal hemangioma which had uncommonly invaded into both the pancreas and duodenum, thus requiring a pylorus preserving pancreaticoduodenectomy (PpPD). A 36-year-old man presented to our hospital with abdominal pain. An enhanced computed tomography scan without contrast enhancement revealed a 12 cm × 9 cm mass between the pancreas head and right kidney. Given the high rate of malignancy associated with retroperitoneal tumors, surgical resection was performed. Intraoperatively, the tumor was inseparable from both the duodenum and pancreas and PpPD was performed due to the invasive behavior. Although malignancy was suspected, pathological diagnosis identified the tumor as a retroperitoneal cavernous hemangioma for which surgical resection was the proper diagnostic and therapeutic procedure. Reteoperitoneal cavernous hemangioma is unique in that it is typically separated from the surrounding organs. However, clinicians need to be aware of the possibility of a case, such as this, which has invaded into the surrounding organs despite its benign etiology. From this case, we recommend that combined resection of inseparable organs should be performed if the mass has invaded into other tissues due to the hazardous nature of local recurrence. In summary, this report is the first to describe a case of retroperitoneal hemangioma that had uniquely invaded into surrounding organs and was treated with PpPD.

A 52-year-old man had bloody stools during chemo-therapy for gastric cancer. A colonoscopy revealed necrotizing ulcer-like changes. A biopsy confirmed the presence of amoebic trophozoites. Subsequently, peritonitis with intestinal perforation developed, and emergency peritoneal lavage and colostomy were performed. After surgery, endotoxin adsorption therapy was performed and metronidazole was given. Symptoms of peritonitis and colonitis resolved. However, the patient's general condition worsened with the progression of gastric cancer. The patient died 50 d after surgery. Fulminant amoebic colitis is very rarely associated with chemotherapy. Amoebic colitis should be considered in the differential diagnosis of patients who have bloody stools during chemotherapy.

The most important achievement in the Paris Agreement is to set up emission reduction target by commitment submitted by each country/ region with the form INDC. However the emission reduction target inside INDCs could not match with the emission pathway for the global to keep a global temperature rise this century well below 2 ℃ and to drive efforts to limit the temperature increase even further to 1.5 ℃ above pre- industrial levels. It is important for countries to do more than their commitment in INDCs, especially in near term. This paper looks at the near term trend for possibilities for further emission reduction compared with INDCs, and found there do have the possibility. It concludes there is space for the four countries/regions to do more than their INDCs submitted to UNFCCC, and see the light towards to a global 2 ℃ target.
