ABSTRACT
Objective To summarize the experience of prevention of biliary tract complications after liver transplantation from organ donation after citizen's death. Methods Clinical data of 88 cases undergoing liver transplantation from organ donation after citizen's death in the Affiliated Zhongshan Hospital of Sun Yat-sen University from October 2008 to December 2016 were retrospectively analyzed. Results Eighty-eight cases were eligible for the standards for organ donation after brain death plus cardiac death according to the Ⅲ national system for organ donation in China. According to the standard procedures, donor livers were successfully harvested and transplanted in 88 recipients. The biliary tract was reconstructed using the bile duct end-to-end anastomosis. The length of bile duct in the donors was shortened as possible. Slight tension should be maintained during anastomosis. Neither primary liver graft nonfunction nor rejection reaction occurred. One recipient suffered from bile leakage and recovered after drainage for 3 weeks. Two patients presented with biliary tract stenosis and mitigated after the placement of biliary tract stent. Conclusions The harvesting of donor liver should be in accordance with the standard procedures. The advantages of extracorporeal membrane oxygenation (ECMO) should be fully utilized to shorten warm and cold ischemia time as possible. Much attention should be diverted to the reconstruction of biliary tract, which contributes to decreasing the risk of biliary tract complications. Favorable clinical efficacy can be achieved in liver transplantation from organ donation after citizen's death.
ABSTRACT
Objective:To optimize the extraction process for the total alkaloids of Longzuan Tongbi Fang by central composite design and response surface method.Methods:The independent variables were the ethanol contention,solvent consumption and extraction time,and the dependent variable was the weighted overall desirability of the content of total alkaloids and kukoline.The extraction process for the total alkaloids of Longzuan Tongbi Fang was optimized by central composite design and response surface method.Results:The optimum extraction conditions were as follows:9-fold amount of solvent was used,refluxed for 130 min,extracted twice,and the ethanol concentration was 75%.Conclusion:The central composite design and response surface method used for the extraction optimization for the total alkaloids of Longzuan Tongbi Fang is very simple and highly predictive.
ABSTRACT
This study was aimed to evaluate effects of different production techniques of Shuxue Tongmai (SXTM) capsules for blood coagulation function and thrombosis formation among mice. The observation was made on the clot-ting time, bleeding time and instauration rate of collagen-adrenaline model of mice. The results showed that com-pared with SXTM II and Ⅲ production technique, the SXTM I production technique of the same dosage group can prolong the clotting time of mice significantly (P < 0.05), and increase the instauration rate of collagen-adrenaline model of mice significantly (P< 0.05). There was no significant difference on the bleeding time of mice between the SXTM I production technique of same dosage group and the saline group. It was concluded that the SXTM had an-ticoagulative and antithrombotic effects. And the SXTM I production technique receives better effects.
ABSTRACT
Objective To introduce the pattern of intestinal parasites infection in Guyana,South America.Methods Direct faecal smears were performed by using 1% Lugol′s iodine wet-mount preparations.Results The infection rate of intestinal parasites in faeces was(6.54%) in 5,200 patients.The intestinal parasites found most commonly were:Hookworm 2.33%(121/5,200);G.lamblia 1.65%(86/5,200);Ascarislumbricoides 0.75%(39/5,200);Whipworm 0.69%(36/5,200);E.histolytica 0.42%(22/5,200).Conclusions Infection rate of intestinal parasites is quite high in the citizen of Georgetown district.
