OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors （DTIs） in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital （the Affiliated Hospital of UESTC）， a multidisciplinary working group was established. Through literature review and the Delphi method， clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework； systematic searches were conducted in CNKI， Medline， Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment，Development and Evaluation （GRADE） approach， and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations （each with an expert consensus rate exceeding 90%） on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection， dosing ranges， key monitoring points， and safety management strategies for parenteral DTIs in various scenarios， including the perioperative period of ventricular assist device implantation， the perioperative period of cardiac surgery， perioperative patients with lower-extremity atherosclerotic disease， the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome， the perioperative period of carotid artery stenting in patients with carotid stenosis， the perioperative period of patients with right heart thrombosis， and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition， warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus， which is formulated based on the best available evidence， provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

Migration is one of the core biological characteristics of migratory birds. The nutrient, energy, and biological flows triggered during this process can facilitate the cross-regional spread of parasites and induce changes in their community structures. This article systematically reviews the interaction between migratory birds and parasites, including the prevalence characteristics of parasites in migratory birds, the vector role of migratory birds in parasite transmission, and the potential impact of parasites on hosts, ecosystems, and humans, in order to provide theoretical support for biodiversity conservation and prevention and control of zoonosis.

Objective:To explore the molecular biological effects of Zu-san-li in the treatment of diseases. Methods:Literatures in CNKI, Wan-fang and VIP databases on acupuncture and moxibustion treatment of diseases from January 1, 1999 to April 30, 2019 were retrieved, and the target of Zu-san-li for treating diseases were obtained. The disease enrichment, GO bioprocess enrichment and KEGG pathway enrichment were performed on these targets. Results:A total of 297 articles were included, involving 196 targets. Six diseases, mainly including tumors, nervous system, cardiovascular system, digestive system and other diseases, 18 GO bioprocess related items and 10 signaling pathways, involving signaling pathways such as immunity, cytokines, and gastrin secretion, what those were enriched.Conclusions:Acupuncture at Zu-san-li can treat diseases of multiple systems, which is related to its multi-target and multi-path mechanism. The study can provide a basis for further elucidating the mechanism of action of acupuncture treatment.

Objective To explore the risk factors for postoperative hypoxemia in patients undergoing Stanford type A aortic dissection surgery.Methods The clinical data of 77 patients with Stanford type A aortic dissection surgery were analyzed retrospectively.Among the patients, 40 patients occurred hypoxemia(hypoxemia group),and 37 patients did not occur hypoxemia(non-hypoxemia group).The preoperative,intraoperative and postoperative clinical data were compared between 2 groups,and the independent risk factors for postoperative hypoxemia were analyzed by multiple Logistic regression analysis.Results The incidence of postoperative hypoxemia in patients with Stanford type A aortic dissection was 51.9% (40/77).The multiple Logistic regression analysis result showed that age (OR =1.088,95% CI 1.018-1.164,P=0.013),body mass index≥25 kg/m2(OR=6.495,95% CI 1.327-31.789,P=0.021),pericardial effusion(OR=6.384,95% CI 1.426-28.576,P=0.015),white blood cell count(OR=1.289,95% CI 1.033-1.609,P=0.024)and using recombinant human coagulationⅦa (OR = 23.757, 95% CI 2.849 - 198.085, P = 0.003) were the independent predictive factors for postoperative hypoxemia in patients with Stanford type A aortic dissection.Conclusions The postoperative hypoxemia in patients with Stanford type A aortic dissection is related with perioperative systemic inflammation, especially in obese patients who should be given anti-inflammatory treatment during perioperative period.Control of bleeding and reducing the recombinant human coagulationⅦa as far as possible can reduce the incidence of postoperative hypoxemia.

Objective To explore the clinical effect of extracorporeal shock wave lithotripsy (ESWL) for the treatment of horseshoe kidney stones.Methods A total of 42 cases of horseshoe kidney stones from March 1987 to January 2015 were enrolled.Among them,33 cases were male and 9 cases were female.Their age range was 19 to 71 years,average age was 42 years old.25 cases got left renal pelvis stone,17 cases were on the right renal pelvis side.The diameter range of stone was 0.4-3.7 cm,the average was 1.8cm.ESWL was applied to treat whole group.The prone position was used to removing calculus.The frequency of treatment was 2000-2700 times,with an average of 2500 times;the treatment voltage was 4-7KV.The gravel time of the treatment was 30-45min,the average was 35min.Results One time for ESWL was 29 cases,two times for ESWL was 8 cases,three times for ESWL was 3 cases,four times for ESWL was 2 cases.The first discharge stones time was 3 to 10 days.There was no special discomfort after operation.40 cases got hematuria after operation,which occurred in 1 to 3 days after ESWL Renal colic was in 7 cases which happened on 1-3 days after ESWL.Condusions Calculi in horseshoe kidney may be treated by ESWL.It is a safe and simple operation.The prone position may bring satisfactory effect.

Objective To evaluate clinical efficacy of extracorporeal shock wave lithotripsy (ESWL) for treating patients with double J (DJ) stent extubation difficulties.Methods A retrospective analysis were conducted from July 1999 to December 2013,total 30 cases (18 male and 12 female) were accepted the ESWL therapy for treating the DJ extubation difficult due to the stone scales surface.The average age in those patients was 46 years (range 24 to 83 years).The average duration of DJ stents indwelling was 8.3 months (range 1.5 to 36.0 months).There were 10 cases with single stone and 20 cases with multiple stones.The distribution of stone location included left kidney in 14 cases,right kidney in 6 cases,left ureter in 3 cases and right ureter in 7 cases.The ureteral stone scales around the DJ stent showed tubular distribution.The distribution of imaging characteristic included kidney stones around the DJ stent joint in 20 cases and surface coarse in 10 cases.The diameter of the stone ranged from 0.7 to 3.2 cm (mean 1.8 cm).All the 30 cases were treated by ESWL with the 2 000-3 300 times frequency (mean 2 800 times).Treatment voltage was 4-8 KV.Results Gravel time ranged from 40 to 70 min (mean 45 min).No intraoperative and postoperative complications occurred.Their DJ stents were easily extubated immediately after ESWL.One week after ESWL,all the patients reported the flushing of the stone.Conclusion ESWL is a simple,convenient and efficacy way to solve the DJ stent extubation difficulties due to the scales surface.
