RESUMEN
Objective:To investigate the application value of donor liver autologous portal venous blood rinse in orthotopic liver transplantation (OLT).Methods:The retrospective cohort study was conducted. The clinicopathological data of 35 pairs of donors and recipients who underwent OLT in the First Affiliated Hospital of University of Science and Technology of China from May 2018 to June 2019 were collected. Of the 35 donors, there were 31 males and 4 females, aged (48±9)years. Of the 35 recipients, there were 25 males and 10 females, aged (47±9)years. Of the 35 recipients, 16 recipients undergoing donor liver autologous portal venous blood rinse were allocated into the portal vein group, and 19 recipients undergoing donor liver albumin water rinse were allocated into the albumin group. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and compari-son between groups was analyzed using the t test. Measurement data of skewed distribution were represented as M(range). Count data were descried as absolute numbers, and comparison between groups was analyzed using the Fisher exact probability. Results:(1) Surgical situations. The anhepatic phase time and arterial blood Ca 2+ concentration within 5 minutes after reperfusion of the recipients were (52±12)minutes and (0.99±0.10)mmol/L in the portal vein group, versus (64±12)minutes and (1.05±0.07)mmol/L in the albumin group, showing significant differences in the above indicators between the two groups ( t=2.94, 2.22, P<0.05). The mean arterial pressure, arterial blood K +concentration and arterial blood pH within 5 minutes after reperfusion of the recipients were (70±24)mmHg (1 mmHg=0.133 kPa), (4.7±1.3)mmol/L and 7.27±0.06 in the portal vein group, versus (71±28)mmHg, (4.6±1.1)mmol/L and 7.30±0.07 in the albumin group, showing no significant difference in the above indicators between the two groups ( t=0.14, 0.30, 1.22, P>0.05). (2) Post-operative situations. Cases with post-reperfusion syndrome (PRS), cases with severe PRS of cardiac arrest, cases with primary graft nonfunction of the recipients were 6, 0, 2 in the portal vein group, versus 8, 1, 1 in the albumin group, showing no significant difference in the above indicators between the two groups ( P>0.05). Total bilirubin on postoperative day 7 of the recipients was (90±52)μmol/L in the portal vein group, versus (166±112)μmol/L in the albumin group, showing a significant difference between the two groups ( t=2.66, P<0.05). International normalized ratio on postoperative day 7, the highest alanine aminotransferase and aspartate aminotransferase within 7 days after operation of the recipients were 2.1±2.0, (1 952±2 813)IU/L and (3 944±6 673)IU/L in the portal vein group, versus 1.8±0.6, (1 023±1 014) IU/L and (2 005±2 910)IU/L in the albumin group, showing no significant difference in the above indicators between the two groups ( t=0.66, 1.23, 1.08, P>0.05). Recipients with hepatic artery complication and biliary complication were 1 and 2 in the portal vein group, versus 0 and 4 in the albumin group, showing no significant difference in the above indicators between the two groups ( P>0.05). There were 3 cases and 2 cases died during the perioperative period in the portal vein group and the albumin group, respectively. (3) Follow-up. Of the 35 recipients, 30 recipients were followed up for 534(range, 28?776)days after operation. During the follow-up, there were 3 patients with postoperative complications in the portal vein group including 2 cases died and 1 case recovered after sympto-matic treatment. There were 5 patients with postoperative complications in the albumin group including 1 case died and 4 cases recovered after symptomatic treatment. Up to the follow-up date, 11 patients in the portal vein group and 16 patients in the albumin group were in good condition. Conclusion:Rinse of the donor liver with autologous portal venous blood during liver transplantation can shorten the time of anhepatic phase, without increasing the occurrence of post-reperfusion syndrome, ischemia re-perfusion injury and biliary tract complications.
RESUMEN
Recent studies show that resveratrol is characterized with its antioxidative and anti-inflammatory effects, and plays an important role in the prevention and treatment of colorectal cancer through modulating intracellular carbohydrate and ceramide metabolism, activating tumor suppressors such as activator of transcription 3 and peroxisome proliferators-activated receptor γ, down-regulating the expression of kirsten rat sarcoma viral oncogene and inhibiting the epithelial-to-mesenchymal transition process of cancer cells.In addition,resveratrol exhibits its broad application prospects in combination therapy.

RESUMEN
Objective To investigate drug resistance mechanism of aminoglycoside-resistant Acinetobacter baumannii by detecting 16S rRNA methylase gene and three common genes of aminoglycoside-modifying enzymes in Acinetobacter baumannii infected patients at EICU. Methods The 48 Acinetobacter baumannii strains were collected,and antimicrobial susceptibility tests were performed by VITEK automicroscan. The MIC was detected by 2-fold agar dilution method,and genes were analyzed by polymerase chain reaction( PCR) . Results Among 48 strains,28 were highly resistant to aminoglycosides and 20 showed lower resistances. The 16S rRNA armA,APH(3')-I,ANT(3'')-Ia,AAC(6')-Ib genes were detected in 71. 43%,60. 71%,82. 14%, and 53. 57%of the 28 highly resistant strains,but only present in 0. 00%,0. 05%,0. 05%,and 0. 05%of the low-resistant isolates(P<0. 01). Conclusion The aminoglycoside-modifying enzymes and 16S rRNA methylase were frequently found in Acinetobacter baumannii clinical isolates,which is closely related to the high-level resistance to aminoglycoside antibiotics.
RESUMEN
Tension pneumopericardium is an uncommon complication of mechanical ventilaton. It may indeed be life-threatening for hemodynamic compromise and circulatory collapse. We present a case of tension pneumopericardium in a patient with a portable ventilator during intrahospital transport for computed tomography scan. Although timely rescue measures were performed, the patient died finally. We report the case to help us to be aware of and take precautions against this fatal condition during intrahospital patient transportation
