| 1 | Percutaneous endoscopic gastrostomy:Indications,technique,complications and management显示文摘Percutaneous endoscopic gastrostomy(PEG)is the preferred route of feeding and nutritional support in patients with a functional gastrointestinal system who require long-term enteral nutrition.Besides its wellknown advantages over parenteral nutrition,PEG offers superior access to the gastrointestinal system over surgical methods.Considering that nowadays PEG tube placement is one of the most common endoscopic procedures performed worldwide,knowing its indications and contraindications is of paramount importance in current medicine.PEG tubes are sometimes placed inappropriately in patients unable to tolerate adequate oral intake because of incorrect and unrealistic understanding of their indications and what they can accomplish.Broadly,the two main indications of PEG tube placement are enteral feeding and stomach decompression.On the other hand,distal enteral obstruction,severe uncorrectable coagulopathy and hemodynamic instability constitute the main absolute contraindications for PEG tube placement in hospitalized patients.Although generally considered to be a safe procedure,there is the potential for both minor and major complications.Awareness of these potential complications,as well as understanding routine aftercare of the catheter,can improve the quality of care for patients with a PEG tube.These complications can generally be classified into three major categories:endoscopic technical difficulties,PEG procedure-related complications and late complications associated with PEG tube use and wound care.In this review we describe a variety of minor and major tube-related complications as well as strategies for their management and avoidance.Different methods of percutaneous PEG tube placement into the stomach have been described in the literature with the'pull'technique being the most common method.In the last section of this review,the reader is presented with a brief discussion of these procedures,techniques and related issues.Despite the mentioned PEG tube placement complications,this procedure has gained worldwide popularity as a safe enteral access for nutrition in patients with a functional gastrointestinal system. | Ata A Rahnemai-Azar Amir A Rahnemaiazar Rozhin Naghshizadian Amparo Kurtz Daniel T Farkas | 2014 | World Journal of Gastroenterology2014，20，24： | 38 |
| 2 | Carcinoma in situ in a 7 mm gallbladder polyp: Time to change current practice?显示文摘Detection of polypoid lesions of the gallbladder is increasing in conjunction with better imaging modalities. Accepted management of these lesions depends on their size and symptomatology. Polyps that are symptomatic and/or greater than 10 mm are generally removed, while smaller, asymptomatic polyps simply monitored. Here, a case of carcinoma-in-situ is presented in a 7 mm gallbladder polyp. A 25-year-old woman, who had undergone a routine cholecystectomy, was found to have an incidental 7 mm polyp containing carcinoma in situ. She had few to no risk factors to alert to her condition. There are few reported cases of cancer transformation in gallbladder polyps smaller than 10 mm reported in the literature. The overwhelming consensus, barring significant risk factors for cancer being present, is that such lesions should be monitored until they become symptomatic or develop signs suspicious for malignancy. In our patient's case this could have led to the possibility of missing a neoplastic lesion, which could then have gone on to develop invasive cancer. As gallbladder carcinoma is an aggressive cancer, this may have led to a tragic outcome. | David Kasle Amir A Rahnemai-Azar Shahida Bibi Vinaya Gaduputi Brian F Gilchrist Daniel T Farkas | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，9： | 8 |
| 3 | Ethylene-inhibiting compound 1-MCP delays leaf senescence in cotton plants under abiotic stress conditions显示文摘Cotton(Gossypium hirsutum L.) plants produce more ethylene when subjected to abiotic stresses, such as high temperatures and drought, which result in premature leaf senescence, reduced photosynthetic efficiency, and thus decreased yield. This study was conducted to test the hypothesis that the ethylene-inhibiting compound 1-methylcyclopropene(1-MCP) treatment of cotton plants can delay leaf senescence under high temperature, drought, and the aging process in controlled environmental conditions. Potted cotton plants were exposed to 1-MCP treatment at the early square stage of development. The protective effect of 1-MCP against membrane damage was found on older compared to younger leaves, indicating 1-MCP could lower the stress level caused by aging. Application of 1-MCP resulted in reduction of lipid peroxidation, membrane leakage, soluble sugar content, and increased chlorophyll content, in contrast to the untreated plants under heat stress, suggesting that 1-MCP treatment of cotton plants may also have the potential to reduce the effect of heat stress in terms of delayed senescence. Application of 1-MCP caused reductions of lipid peroxidation, membrane leakage, and soluble sugar content, together with increases in water use efficiency(WUE), water potential, chlorophyll content, and fluorescence quantum efficiency, compared to the untreated plants under drought, suggesting that 1-MCP treatment of cotton plants may also have the ability to reduce the level of stress under drought conditions. In conclusion, 1-MCP treatment of cotton should have the potential to delay senescence under heat and drought stress, and the aging process. Additionally, 1-MCP is more effective under stress than under non-stress conditions. | CHEN Yuan J T Cothren CHEN De-hua Amir M H Ibrahim Leonardo Lombardini | 2015 | Journal of Integrative Agriculture2015，14，7： | 3 |
