Objective To compare the yield of endoscopic ultrasonography guided fine needle aspira-tion (EUS-FNA) with 3 different sample processing methods. Methods The clinical data of 118 patients, who underwent EUS-FNA performed by one physician from February 2005 to September 2008, were retrospectively analyzed. The FNA sample processing methods included liquid-based cytology, on-site cytology and smear method. The pathological diagnosis was classified as definite, suspicious malignancy, dissatisfying sampling and indefinite. Results The success rate of obtaining samples through on-site cytological procedure was 95.2% (40/42), which was significantly higher than that of conventional smear (32/47, 68%, P <0. 05), and was higher than that of liquid-based cytological method (26/29, 89. 7% ), but without significant differ-ence (P>0.05). The yield of definite diagnosis with liquid-based cytology and on-site cytology were 82.8% (24/29) and 78. 6% (33/42), respectively, which were both significantly higher than that of smear method (57. 4%, 27/47, P <0. 05). The sensitivity and accuracy of on-site cytology were higher than those of smear method and liquid-based cytology, but without significant differences (P >0. 05). Conclusion Compared with conventional smear method, an-site cytology and liquid-based cytology yield more results from EUS-FNA.

OBJECTIVETo observe the effect of sodium bicarbonate combined with ulinastatin on cholinesterase activity for patients with acute phoxim pesticide poisoning.
METHODSA total of 67 eligible patients with acute phoxim pesticide poisoning, Who were admitted to the emeryency department of hospital from March 2011 to February 2014, Acording to different treatments au patients were randomly divided into the conventional treatment group (n=34) and the sodium bicarbonate+ulinastatin group (n=35) . The conventional treatment group were given thorough gastric lavage with water, the sodium bicarbonate + ulinastatin group were given gastric lavage with 2% sodium bicarbonate solution. Both groups were given such treatments as catharsis, administration of oxygen, fluid infusion, diuresis, and antidotes such as atropine and pralidoxime methylchloride. On the basis of comprehensive treatment, people in the sodium bicarbonate+ulinastatin group were given 5% sodium bicarbonate injection and ulinastatin. The clinical effect of the two groups were compared.
RESULTSThe serum cholinesterase activity of the sodium bicarbonate+ulinastatin group was significantly higher than the conventional treatment group from the 5th day, and the difference was statistically significant (P<0.05) . The total atropine dosage, total pralidoxime methylchloride dosage and hospitalization days were better than the conventional treatment group, and the differences were statistically significant (P<0.05) . The difference in the time of atropinization between the two groups was not statistically significant (P>0.05) . The results of arterial blood pH, HCO3- of the sodium bicarbonate + ulinastatin group were higher than the conventional treatment group, and the difference of HCO3- at the 10th day was statistically significant (P<0.05) .
CONCLUSIONSSodium bicarbonate combined with ulinastatin can improve the therapeutic effect and reduce complications in the treatment of acute phoxim pesticide poisoning, and have beneficial effects on the recovery of cholinesterase activity.
