ObjectiveTo explore the effect of the indirect laryngoscope in the young child adenoidectomy.Methods35 young children with adenoidoctomy were given the general anesthesia and the suspension of soft palateby catheter,looking straight ahead under the indirect laryngoscope,the large adenoid body was cutted and attracted.ResultsAftersurgery,both the snort and suppressed breath symptoms were improved significantly,none complication occured.ConclusionUnder the indirect laryngoscope,adenoidectomy was not only safe and effective but also easy,feasible and economical.

Objective To analyze the curative effect of blood transfusion on 100 patients undergoing liver transplantation,to efficiently enhance hemostasis and coagulation function of the patients,to lower the incidence of the operative complications,and to put forward the guideline of blood transfusion to the patients undergoing liver transplantation.Methods The volumes of red blood cells concentrates(RCCs),fresh frozen plasma(FFP),cryopreserved platelets,and cryoprecipitate transfused to the patients undergoing liver transplantation were measured before,during and after the operation respectively.The volumes of blood components transfused to the 50 patients in the former stage and 50 patients in the later stage of liver transplantation in our hospital were also measured respectively.Results The mean volume of the blood components transfused to each patient was 3 334ml.The ratios of the transfused blood volumes to 100 patients were 4.3%,53.4% and 42.3% before,during and after operation respectively.The rate of blood components transfusion was 100% and the ratio of transfused blood volumes to the patients between RCCs and FFP was 1.45:1.The mean volumes of the transfused blood and the operative complications of 50 patients in the former stage of liver transplantation of our hospital were significantly higher than those of the 50 patients in the later stage.Conclusion It is very vital in the scientific,safe and reasonable blood transfusion for the success of liver transplantation,which significantly lowers the incidence of operative complications,such as massive haemorrhage during and after operation,and thrombosis at inosculation of liver artery and portal vein.

Objective:To explore the effect of rapamycin on 1-methyl-4-phenylpyridinium iodide (MPP+ )-induced activation of Nod-like receptor protein 3 (NLRP3) inflammasome in microglia.Methods:The BV2 microglia cells were divided into control group, model group and rapamycin group.The model group and rapamycin group were treated by MPP+ to activate NLRP3 inflammasome, and rapamycin group was pretreated with rapamycin.Quantitative real-time PCR (RT-qPCR) was used to detect the mRNA levels of NLRP3, apoptosis-associated speck-like protein (ASC) and caspase-1.Immunofluorescence was used to detect the protein expression of NLRP3 and interleukin-1β (IL-1β). Western blot was carried out to assess the protein expression of NLRP3, ASC, caspase-1, beclin1 and microtubule-associated protein 1 light chain 3 (LC3).Results:The mRNA levels of NLRP3, ASC and caspase-1 in model group were higher than those in control group ( t=4.825, 3.015, 5.853, all P<0.05). The mRNA levels of NLRP3 and caspase-1 in rapamycin group were lower than those in model group ( t=2.75, 2.89, both P<0.05). In model group, the protein expressions of NLRP3 (1.54±0.22), ASC (1.02±0.13) and caspase-1 (1.42±0.30) were higher than NLRP3 (0.66±0.15), ASC (0.41±0.14) and caspase-1 (0.70±0.10) in control group ( t=5.653, 5.602, 3.964, all P<0.01), while the protein expression of beclin1 (0.28±0.09) and LC3II/LC3I ratio(0.69±0.14) were lower than beclin1 (0.60±0.11) and LC3II/LC3I (1.29±0.23) in control group ( t=4.010, 3.982, both P<0.01). The protein expressions of NLRP3 (0.80±0.18) and ASC (0.68±0.14) in rapamycin group were lower than those in model group ( t=4.413, 3.077, both P<0.05), while the protein expression of beclin1 (0.65±0.20) and LC3II/LC3I ratio(1.42±0.36) were higher than those in model group ( t=2.965, 3.278, both P<0.05). Conclusion:MPP+ activates NLRP3 inflammasome and impairs autophagic function in microglia.Rapamycin inhibits MPP+ -induced activation of NLRP3 inflammasome by restoring autophagic impairment in microglia.

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.
