Objective To monitor and modulate the coagulation disorder during operation in patients undergiong allogeneic liver transplantation. Methods PT, TT, APTT, FIB, HB, PLT count, sonoclot coagulation and platelet function were measured dynamically in 10 patients during anesthesia and operation. Results After coagulants were used, the above parameters pertaining to coagulation function were improved obviously. All of above coagulation parameters were severely abnormal in the period from 30 minutes before anesthesia to 20 minutes after portal vein recirculation. The hypocoagulability was significantly improved at the end of operation by target supplementation of prothrombin complex, fibrinogen, fresh platelets, and other coagulants, complementing large amount of fresh blood plasma. Notably, severe hemorrhage and thrombosis leading to re-operation did not happen in all the recepients. Conclusion The relationship of the local hypercoagubility at the anastomosis and the systemic hypocoagulation should be concerned to prevent coagulation and thrombosis during operation of liver transplantation.

OBJECTIVE:To probe into the status quo of the drug resistance and the medication of pseudomonas aeruginosa so as to provide references for the clinic in the controlling of pseudomonas aeruginosa infection.METHODS:The susceptive rates of the susceptibility test performed on 148 pseudomonas areuginosa infection cases confirmed in 2004 in our hospital were collected statistically and a whole range tracking statistics were conducted on the use of antibacterials.RESULTS:Pseudomonas aeruginosa had a strong drug resistance,which had a different degree of drug resistance to all antibacterials;Antibiotics like piperacillin/tazobactam,ceftazidime and carbopenem took the lead in terms of their susceptive rates,which stood at 75.68%,73.65%and 70.27%,respectively;The cross resistances of the third generation cephalosporins and the compound agents of the third generation cephalosporins and their enzyme inhibitor were serious and which kept increasing rapidly;The adoption rates for the susceptive kinds were less than 50%before the susceptibility test.CONCLUSION:An effective way to control pseudomonas aeruginosa infection is to conduct strain culture and isolation and perform susceptibility test as early as possible.

Objective:To explore the efficiency of a new scoring system of gastric cancer screening for early gastric cancer in health examination population.Methods:The risk score of gastric cancer was assessed based on the new scoring system in health examination population. A notice for further gastroscopy was sent to the medium-risk and high-risk people. Gastroscopy was performed on those who agreed to undergo the examination.Results:From January to April 2019, a total of 5 357 people in health system visited the Physical Examination Center of Shanghai Songjiang Clinical Medical College of Nanjing Medical University for health examination. Seven hundred and forty people were classified as medium- and high-risk groups by the new screening system, 576 in medium-risk group, and 164 in high-risk group. Among them, 131 cases (17.70%) came for further gastroscopy, of whom 91 (69.47%) were in the medium-risk group and 40 (30.53%) in the high-risk group. After gastroscopy, 4 cases of gastric cancer and 1 case of esophageal cancer were detected, and both were early cancer. In the medium-risk group, 2 cases (2/91, 2.20%) of early gastric cancer and 1 case (1/91, 1.10%) of early esophageal cancer were found. In the high-risk group, 2 cases (2/40, 5.00%)of early gastric cancer were found. The tumor detection rate of high-risk group (5.00%) was higher than that of medium-risk group (3.30%), but there was no significant difference ( P>0.05). Conclusion:Risk stratification with the new scoring system of gastric cancer screening can improve the detection rate of early gastric cancer.
