Objective To investigate the related factors that affect the short outcome of abdominal surgery among elderly patients with acute abdomen.Methods Clinical data of 378 patients aged >60 years with acute abdo-men were retrospectively analyzed.The key factors under analysis in this study were the occurrence of major complica-tions,death from any cause within 30 days and related factors after the operation.Results The most common diagno-ses were acute appendicitis (134 cases,35.4%),biliary tract disease (96 cases,25.4%),intestinal obstruction (68 cases,20.0%)and inguinal hernia(42 cases,11.1%).The majority of patients(327cases,86.5%)underwent open surgery.12cases(23.5%)of all 51 cases underwent laparoscopic surgery were converted to open surgery.The 30 day mortality rate and rate of operation -related complications were 9.5% and 22.0%,respectively.Analysis showed that patients'age,low body mass index,open surgery and ASA grade Ⅲ or above may increase mortality(all P <0.05).Conclusion The acute abdomen in elderly patients was with much complications,operation treatment is still the first choice.The patient's older age,low body mass index,open surgery may increase the mortality rate.ASA grade higher may predict a bad prognosis.The operation of elderly patiens had a high morbidity and mortality,as general surgeon,we should pay more attention to acute abdomen in elderly patients.
5.Adipose tissue engineering construction using adipose-derived stem cells and scaffolds in breast reconstruction
Chinese Journal of Tissue Engineering Research 2018;22(14):2272-2277
BACKGROUND:The development of adipose tissue engineering has solved a series of problems and brought new ideas for breast reconstruction. OBJECTIVE:To summarize the main biological characteristics of scaffolds, seed cells and adipose grafts for adipose tissue engineering construction, as well as their application prospects in breast reconstruction. METHODS:With the key words of "scaffold, mesenchymal stem cells, adipose tissue engineering, breast reconstruction, vascularization" in Chinese and English, respectively, a retrieval of CNKI and PubMed was performed for relevant articles published from 1999 to 2017. After initial screening, the eligible articles were further detailed, analyzed and summarized. RESULTS AND CONCLUSION:Scaffold materials with low immunogenicity, especially the decellularized adipose tissue, have a unique advantage in adipogenic induction that can be used to support the regeneration of human organs and tissues. Adipose-derived stem cells can also be used as the priority for adipose tissue engineering construction, which can promote tissue development and regeneration in vivo. However, much less is known about the use of adipose tissue engineering in breast reconstruction and the implementation of long-term stable growth of the adipose tissues. Further investigations are indispensable on how to realize breast reconstruction using tissue-engineered adipose so as to construct and maintain a stable structure entity throughout the entire patient's life. Therefore, strict selection of seed cells, scaffolds and cytokines is considered pivotal in the construction of cell microenvironment.

BACKGROUND:With the development of industry and agriculture, organotin compounds have been widely used in China. Organotin compounds cause a common occupational poisoning. The toxicity of organotin was reported in animal studies; however the reports about human organotin intoxication are very rare. In this study we retrospectively analyzed the clinical manifestations of 15 organotin-poisoned patients who had been treated at our hospital from 2002 through 2007. METHODS:Fifteen patients with organotin poisoning were admitted to Sir Run Run Shaw Hospital Affiliated to Zhejiang University School of Medicine from 2002 to 2007. They were 9 males and 6 females, aged from 25 to 52 years. Clinical manifestations and Glasgow Coma Scales showed that the poisoning was mild in 4 patients, moderate in 6 and severe in 5. The severe patients were given glucocorticoid after hospitalization by intravenous guttae of 500 mg methylprednisolone for the first day, followed by 160 mg methylprednisolone per day for three days, and then 80 mg methylprednisolone per day for another three days. Potassium glutamate and sodium glutamate were intravenously dripped to reduce blood ammonia; intravenous guttae plus oral administration of potassium 9 g/day was used to correct intractable hypokalemia; sodium bicarbonate was used to correct metabolic acidosis, and sedatives were used to control spasm and twitch; mechanical ventilators were used in 4 patients with dyspnea. RESULTS:Most of the patients showed elevated level of blood ammonia, decreased level of blood potassium and metabolic acidosis, but some had demyelination changes shown by CT and MRI. Treatments included correction of metabolic acids, blood potassium and ammonia, and mechanical ventilation when necessary. For patients with injuries of the nervous system, glucocorticoids were given immediately after hospitalization. These patients showed intractable hypokalemia and metabolic acidosis during the treatment. Forteen patients recovered completely without long-term side-effect. One patient in the aphasiac stage restored the linguistic capacity during a 6-month follow-up. CONCLUSIONS:Elevated level of blood ammonia, decresed level of blood potassium, and metabolic acidosis are common in patients with organotin poisoning. Demyelination can be observed in patients with severe poisoning. The abnormalities of the patients are reversible after suitable treatments.
