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.

Congenital heart disease (CHD) is a congenital malformation resulting from abnormal embryonic development of the heart and great vessels, accounting for approximately 25% of all congenital malformations. Children with CHD are often complicated by short stature. Although surgical treatment can improve their growth and development to a certain extent, some children still experience growth retardation after surgery. Recombinant human growth hormone (rhGH) is the main drug for treating short stature, but its efficacy and safety in the treatment of patients with concomitant CHD warrant further investigation. This article reports six cases of children with CHD and short stature who were treated with rhGH. Through a literature review, we summarize and discuss the therapeutic efficacy, follow-up experiences, and adverse reactions of rhGH treatment, aiming to provide references for clinicians in applying rhGH to treat patients with CHD and short stature.

BACKGROUND:Sarcopenia obesity is characterized by the coexistence of sarcopenia and obesity with a continuously increasing prevalence.Aerobic exercise can alleviate the progression of sarcopenic obesity,but the overall metabolic changes in skeletal muscle after exercise are still unclear.OBJECTIVE:To investigate the effects of exercise on various aspects of the energy metabolic pathways in the skeletal muscle of mice with sarcopenic obesity.METHODS:Male C57BL/6J mice were randomly divided into normal control(normal diet)and model(high-fat diet)groups.After 12 weeks of feeding,sarcopenic obesity model mice were screened by body mass and behavior assessments.The sarcopenia obesity mice were then divided into the sedentary and exercise groups.Mice in the exercise group were subjected to treadmill training on the basis of a high-fat diet.After 8 weeks of intervention,body mass,lipid metabolism,muscle volume of calf muscle group of the hind limb,skeletal muscle morphology,and expressions of energy metabolic pathway-related genes were detected.RESULTS AND CONCLUSION:Compared with the normal control group,the levels of triglycerides,total cholesterol,and free fatty acid in the sedentary group were significantly increased,along with significantly increased lipid droplets in skeletal muscle(P<0.05).Compared with the sedentary group,all of the above indicators in the exercise group showed a significant decreasing trend(P<0.05).Compared with the normal control group,grip strength and fatigue latency time,muscle volume,and fiber cross-sectional area were significantly decreased in the sedentary group,but the mRNA expression of Atrogin-1 and Murf-1 was elevated(P<0.05).Compared with the sedentary group,grip strength and fatigue latency time,muscle volume,and fiber cross-sectional area were significantly improved in the exercise group(P<0.05),while the mRNA expression of Atrogin-1 and Murf-1 was reduced(P<0.05).Compared with the normal control group,the mRNA expression of intramuscular transcription factors Pparα and Pgc-1α was decreased in the sedentary group(P<0.05),the mRNA expression of fatty acid synthesis-related enzymes Srebp1c and Fasn was elevated(P<0.05),and the mRNA expression of the β-oxidation system Cpt1β,Acox1,Acox3 and fatty acid metabolism Arf1 and Plin3 was decreased(P<0.05).Compared with the sedentary group,the abnormal expression of the above genes was significantly reversed in the exercise group(P<0.05).To conclude,aerobic exercise can alleviate lipid deposition and improve muscle quality and strength of sarcopenic obesity mice by regulating the expression of genes in the intramuscular energy metabolism network.

Background and aims:Studies indicate that the gut microbiota and its metabolites are involved in the progression of cardiovascular diseases,and enterohepatic circulation plays an important role in this progression.This study aims to identify potential probiotics for the treatment of unstable angina(UA)and elucidate their mechanisms of action.Methods:Initially,the gut microbiota from patients with UA and control was analyzed.To directly assess the effects of Bifidobacterium supplementation,10 patients with UA were enrolled and administered Bifidobacterium(630 mg per intake twice a day for 1 month).The fecal metagenome,serum trimethyl-amine N-oxide(TMAO)levels,and other laboratory parameters were evaluated before and after Bifido-bacterium supplementation.Results:After supplementing with Bifidobacterium for 1 month,there were statistically significant dif-ferences(P＜0.05)in TMAO,aspartate aminotransferase,total cholesterol,and low-density lipoprotein compared to before.Additionally,the abundance of Bifidobacterium longum increased significantly,although the overall abundance of Bifidobacterium did not reach statistical significance.The gut micro-biota,metabolites,and gut-liver axis are involved in the progression of UA,and potential mechanisms should be further studied.Conclusions:Metagenomic analysis demonstrated a reduced abundance of Bifidobacterium in patients with UA.Supplementation with Bifidobacterium restored gut dysbiosis and decreased circulating TMAO levels in patients with UA.This study provides evidence that Bifidobacterium may exert cardiovascular-protective effects through the gut-liver-heart axis.

OBJECTIVE: To explore the genetic basis for fetus with bilateral lateral ventriculomegaly. METHODS: Fetus umbilical cord blood and peripheral blood samples of its parents were collected. The fetus was subjected to chromosomal karyotyping, whilst the fetus and its parents were subjected to array comparative genomic hybridization (aCGH). The candidate copy number variation (CNV) were verified by qPCR, Application goldeneye DNA identification system was used to confirm the parental relationship. RESULTS: The fetus was found to have a normal karyotype. aCGH analysis indicated that it has carried a 1.16 Mb deletion at 17p13.3, which partially overlapped with the critical region of Miller-Dieker syndrome (MDS), in addition with a 1.33 Mb deletion at 17p12 region, which is associated with hereditary stress-susceptible peripheral neuropathy (HNPP). Its mother was also found to harbor the 1.33 Mb deletion at 17p12. qPCR analysis confirmed that the expression levels of genes from the 17p13.3 and 17p12 regions were about the half of that in the normal control, as well as the maternal peripheral blood sample. Parental relationship was confirmed between the fetus and its parents. Following genetic counseling, the parents has chosen to continue with the pregnancy. CONCLUSION The fetus was diagnosed with Miller-Dieker syndrome due to the de novo deletion at 17p13.3. Ventriculomegaly may be an important indicator for prenatal ultrasonography in fetuses with MDS.
