Vein graft (VG) failure (VGF) is associated with VG intimal hyperplasia, which is characterized by abnormal accumulation of vascular smooth muscle cells (VSMCs). Most neointimal VSMCs are derived from pre-existing VSMCs via a process of VSMC phenotypic transition, also known as dedifferentiation. There is increasing evidence to suggest that ginger or its bioactive ingredients may block VSMC dedifferentiation, exerting vasoprotective functions; however, the precise mechanisms have not been fully characterized. Therefore, we investigated the effect of ginger on VSMC phenotypic transition in VG remodeling after transplantation. Ginger significantly inhibited neointimal hyperplasia and promoted lumen (L) opening in a 3-month VG, which was primarily achieved by reducing ferroptotic stress. Ferroptotic stress is a pro-ferroptotic state. Contractile VSMCs did not die but instead gained a proliferative capacity and switched to the secretory type, forming neointima (NI) after vein transplantation. Ginger and its two main vasoprotective ingredients (6-gingerol and 6-shogaol) inhibit VSMC dedifferentiation by reducing ferroptotic stress. Network pharmacology analysis revealed that 6-gingerol inhibits ferroptotic stress by targeting P53, while 6-shogaol inhibits ferroptotic stress by targeting 5-lipoxygenase (Alox5), both promoting ferroptosis. Furthermore, both ingredients co-target peroxisome proliferator-activated receptor gamma (PPARγ), decreasing PPARγ-mediated nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 1 (Nox1) expression. Nox1 promotes intracellular reactive oxygen species (ROS) production and directly induces VSMC dedifferentiation. In addition, Nox1 is a ferroptosis-promoting gene that encourages ferroptotic stress production, indirectly leading to VSMC dedifferentiation. Ginger, a natural multi-targeted ferroptotic stress inhibitor, finely and effectively prevents VSMC phenotypic transition and protects against venous injury remodeling.

The condylar cartilage was adapted to hypoxic conditions in vivo. However, condylar cartilage cells exposed in normoxia in vitro affect the chondrocyte phenotype and cartilage matrix formation. This condition also resulted in great difficulty in chondrocyte research. Culturing chondrocyte should be simulated in in vivo hypoxia environment as much as possible. The hypoxia-inducible factor-1α (HIF-1α) demonstrates an important transcription factor of adaptive response to hypoxic conditions. HIF-1α also plays an active role in maintaining homeostasis and function of chondrocytes. This review summarized current knowledge of the HIF-1α structure, signaling pathway, and mechanism of HIF-1α in the condylar cartilage repair.

Objective To explore the appropriately operative chance , method, and perioperative management of coronary arterybypass grafting (CABG) in the patients with severe left main artery (LMA) stenosis with three-vessel-disease.Methods A total of296 patients with severe LMA stenosis with three-vessel-disease who underwent CABG surgery was analyzed retrospectively from 2003through 2013.Of them, 276 patients underwent conventional coronary artery bypass surgery on pump ( CCABG)and 20 patients underwentoff-pump CABG( OPCAB); 172 Patients was over 60 years old (58.1%)and 246 patients (83.10%) had concomitant diseasesincluding valve lesion, hypertension, diabetes, myocardial infarction, left ventricular aneurysm with septal defect , stroke, renal failure,and cancer.Left internal mammary artery use was in 281 patients (95.1%); and 32 patients were implanted intra-aortic ballonpump(IABP) perioperatively.Results There were 7 cases(2.36 %) death of postoperative low cardiac output , ventricular fibrillation,cerebral infarction, renal failure, and multiple organ failure, respectively.Postoperative complications were low cardiac output ,respiratory failure , ventricular fibrillation, cereboembolism, cardiac tampomade, renal failure, stroke, and multiple organ failure.Afterfollow-up 2 to 84 months, there was 3 death in which 2 death of cardiac factors.Conclusions CCABG was a safe and effectivemethod in patients with severe LMA stenosis with severe three -vessel-disease.Preoperative insertion of IABP can certainly avoid the po -tential operative risk factor and significantly decrease the mortality and morbidity .

Objective To investigate the pollution condition of Salmonella in food with phage. Methods Salmonella in 413 samples of food were detected by the diagnosis of Salmonella phage with biochemical and serological identification. Results 119 Salmonella were detected in 99 positive samples and the isolating rate was 24%. Conclusion The disservice of Salmonella is mainly from the meat food and eggs. The detection method of phage is fast,convenient and reliable.

Objective To explore the value of three-dimensional interactive localization of the anterior ethmoidal canals(AECs)in minimally invasive nasal surgery.Methods Thin-section three-dimensional CT images of the paranasal sinus in 80 patients(160 sides)were analyzed by using interactive localization system.The length and angulation of the AECs were recorded.The relationship between the positions of the AECs and anatomical landmarks were viewed in coronal and sagittal planes.Results The length and angulation of the AECs were(6.9?1.8)mm and(126.6?16.0)?,respectively.The distance between the anterior ethmoidal foramen and the anterior ethmoidal canal to the roof was(7.0?2.2)mm and(2.8 ? 2.0)mm,respectively.The AEC was identified as a suspending separate canal in 35.0%(56/160)sides.In the AECs plane on coronal images,the sagittal part of middle turbinate was found as 74.4%(119/160),the basal lamella of middle turbinate was 25.0%(40/160),and the superior turbinate was 0.6%(1/160).While on the sagittal planes,the position of AECs located on the basal lamella of ethmoida,on the basal lamella of middle turbinate,between the basal lamella of uncinate process and the basal lamella of ethmoida,between the basal lamella of ethmoida,and the basal lamella of middle turbinate were found in 23.8%(38/160),45.0%(72/160),1.2%(2/160)and 30.0%(48/160)of the cases,respectively.Conclusion AECs can be measured and located correctly by three-dimensional interactive system.
