In order to establish a specific,rapid and convenient method for the detection of Campy-lobacter jejuni(C.jejuni).A set of specific primers and a probe that do not cause false positives were designed with the hipO gene of C.jejuni as the target,and the 5'ends of the downstream primers and probes were labeled with biotin and fluorescein,respectively.C.jejuni-RPA-LFD had no cross-reactivity with Klebsiella pneumoniae,Escherichia coli,Pseudomonas,Bacillus cereus,Pasteurella,Proteus mirabilis,and Salmonella typhimurium,and the optimal reaction system was 37 ℃,25 min,and its sensitivity could reach 3.93×100 copies/μL,and 1 × 102 CFU/mL of C.jejuni contaminated stool samples could be detected in the simulated detection.The C.jejuni-RPA-LFD established in this study has the advantages of good specificity,simplicity,rapidity and high sensitivity,which provides an effective way for the rapid diagnosis of C.jejuni and the con-trol of the spread of C.jejuni at the grassroots level of livestock and poultry farming.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the effect of diuretic (furosemide) therapy on kidney injury induced by melamine and cyanuric acid in rats. Methods 36 male Spragne Dawley rats were random disided into 3 groups. Group A was treated with 2mL of water daily, group B was treated with melamine and cyanuric acid ( each 100 mg/kg) daily for 4 days and then 2ml of water daily, group C was treated with the same as group B at the first 4 days and then treatment with furosemide (20mg/kg) daily. Samples of blood and 24h urine were collected to detective biochemical indexes, and kidney sections were performed on days 4 and 11 ( each end point, n = 6). The kidneys were observed with histopathology and renal crystal deposition scores were determined. Results On the 4th day, group B and group C were resulted in acute kidney injury such as oliguria [ ( 3. 39 ± 1.02 ) ml, ( 3. 20 ± 0. 86 ) ml ] and high serum creatinine [ ( 153.54 ±27. 08)μmol/L, (160. 11 ± 19. 55)μmol/L] and renal melamine cyanurate crystal were found in the renal tissues. On the 11th day, the renal crystal deposition score in the rats was reduced by 9. 52% ( P >0. 05). Compared with those of the 4th day in group B, it reduced by 63.63%( P <0.05) in group C. Urine volume were increased significantly compared with those of the 4th day( P < 0. 05 ) in group C [ from (3.20±0. 86)ml to (25.96 ±5.97)ml] and group B [ from(3. 39 ± 1.02)ml to (8. 57 ± 1.66)ml] , and Urine volume in group C was increased significantly more than that in group B ( P < 0. 05 ). The serum creatinine was obviously reduced as compared with those of the 4th day in group B and C( P <0.05), from[ (153. 54±27.08) μmol/L] to [ ( 106. 10 ±5.53) μmol/L] in group B and from [ ( 160. 11 ± 19. 55) μmol/L] to [ (67. 17 ± 12. 80 ) μmol/L] in group C, but the serum creatinine in group B was still higher than that in group A and C ( P < 0. 05). Conclusions Furosemide can attenuate the damage of acute kidney injury induced by melamine and cyanuric acid.

ObjectiveTo investigate the changes of arterial base deficits (BD) in the early stageof extensive burned patients. MethodsWe perform a retrospective review of 126 patients with a totalbody surface area (TBSA) over 30% whose resuscitations were initiated with the Ruijin formula to ob-serve the BD changes and analyze the relationship of BD and TBSA at different postburn time intervals insurvivors and deaths. ResultsWithin 48h after burn injury, the BD value improved gradually. Thedifference between survivors and nonsurvivors was significant at 4 to 8h interval after burn injury ( P <0.05). BD was correlated with TBSA strongly during 4 to 16h after burn injury ( P ≤0.05)in nonsur-vivors, but not in survivors. The incidence of the shock－ related complications in survivors was higherthan in nonsurvivors. ConclusionBD could be one of monitor index in the shock stage after severeburM injury.
