Objective To analyze the change in the concentration of IL-17 and IL-10 inflammatory factors among the deadaptation personnel who returned from the plateau.Methods A total 21 healthy males were investigated who averaged 25 years in age, lived permanently in the plains (200 m), and once stayed to the plateau (Lasha) for 6 months.Their venous blood was collected at three time points:the day before ascending to the plateau(control), the second day after return to the plains(d2) and the 30th day(d30), respectively.Their serum was seperated from the whole blood and the level of IL-17A and IL-10 was detected by ELISA method.Results The concentration of IL-17A and the IL-17A/IL-10 ratio were significant increased at d2 and d30, respectively, compared with control (P<0.05).Compared with d2, IL-17A and the IL-17A/IL-10 ratio were decreased obviously at d30(P <0.05).The level of IL-10 at d2 and d30 was significantly reduced compared with control ( P <0.05), but increased at d30 compared with d2.Correlative analysis showed that there was a negative correlation in the levels of IL-10 and IL-17A between control, d2 and d30, respectively (r1=0.948, P<0.05;r2=0.969, P<0.05;r3=0.972, P<0.05).A significant negative correlation was observed in the alteration levels of IL-10 and IL-17A between the three groups(r4=-0.793, P<0.05; r5=-0.756, P<0.05). Conclusion The concentration of inflammatory factors among the plateau deadaptation patients is imbalanced, but it is gradually reduced with time.The mechanism is still not clear.

Objective:To investigate the effect in lumbar mobility and stress of the facet joint and end plate after implantation of the movable artificial lumbar spine so as to lay a biomechanical foundation for its clinical application.Methods:Total lumbar CT data of a healthy adult male were selected to construct a finite element analysis model and its effectiveness was validated (physiological group). Two groups were replicated after removing the L 3 vertebral body and adjacent discs of the model in physiological group. One group was placed with each component of the movable artificial lumbar spine to construct the non-fusion model (non-fusion group). The other group was placed with titanium cage, titanium plate and other to construct the fusion model (fusion group). The models in the three groups were loaded with 500 N axial load and 10 Nm axial load, and the torque load was used to simulate the movement in six directions: forward flexion, backward extension, left and right lateral bending, and left and right torsion. The lumbar mobility and stress peak and distribution of the proximal facet joints (J 1-2, J 4-5), L 2 inferior endplate and L4 superior endplate at the three model operating sites (L 2-3, L 3-4) and adjacent segments (L 1-2, L 4-5) under the same conditions were compared. Results:The range of motions of the surgical site in flexion, extension, left bending, right bending, left torsion and right torsion were L 2-3of 3.9°-8.7° and L 3-4 of 3.6°-8.4° in non-fusion group, significantly increased compared with fusion group (L 2-3 0.1°-0.2°, L 3-4 0.1°-0.1°) and slightly increased compared with physiological group (L 2-3 2.3°-6.0°, L 3-4 2.3°-7.1°). The range of motions of the adjacent segments in the above six directions were L 1-2 of 1.4°-4.3° and L 4-5 of 1.4°-6.0° in non-fusion group, smaller than those in fusion group (L 1-2 2.1°-6.1°, L 4-5 3.3°-8.6°) and similar to those in physiological group (L 2-3 2.3°-6.0°, L 3-4 2.3°-7.1°). The peak values of von Mises stress in the proximal facet joints were J 1-2 of 7.07-19.21 MPa and J 4-5of 6.12-12.99 MPa in non-fusion group, similar to those in physiological group (J 1-2 8.42-18.53 MPa, J 4-5 7.49-11.70 MPa) and smaller than those in fusion group (J 1-2 10.54-21.16 MPa, J 4-5 10.63-16.13 MPa). The maximum von Mises stress of the L 2 inferior endplate and L 4 superior endplate in the above six directions was 29.39-54.72 MPa and 32.31-47.87 MPa in non-fusion group, significantly increased compared with the L 2 inferior endplate (21.20-42.07 MPa), L 4 superior endplate (22.50-36.76 MPa) and L 2 inferior endplate (11.04-29.55 MPa) in fusion group and the L 4 superior endplate (13.12-21.32 MPa) in physiological group. Conclusion:Compared with the traditional fusion prostheses, the placement of the movable artificial lumbar spine can reconstruct the range of motion of the surgical site in the direction of flexion, extension, lateral bending and torsion, greatly reduce the impact on the stress of adjacent facet joints and the range of motion of adjacent segments, and theoretically reduce the incidence of prosthesis subsidence.

Cancer therapy-related cardiovascular toxicity(CTR-CVT)is gradually becoming a critical factor affecting the prognosis of cancer survivors.Vascular endothelial growth factor(VEGF)and its receptor inhibitors(VEGFIs),developed as novel anti-cancer drugs targeting VEGF,are now widely used in clinical practice.They can extend the survival period of the cancer patients and improve the prognosis of the patients.However,the hypertension induced by VEGFIs,as the most common CTR-CVT,may limit and impact their use and leads to severe cardiovascular diseases(CVD).It is essential to closely monitor blood pressure in the cancer patients treated with VEGFIs,conduct early assessments,and optimize the management to achieve the best anti-cancer efficacy and minimize the risk of CTR-CVT.This review discusses the clinical manifestations,pathogenesis,diagnosis,and treatment strategies of VEGFIs-related hypertension,in order to provide better guidances for managing and addressing VEGFIs-related hypertension for the clinicians.

Lipoprotein(a)[Lp(a)]is a highly polymorphic lipoprotein molecule composed of apolipoprotein A(apo A),apo B100,and cholesterol ester core;calcific aortic valve stenosis(CAVS)is a multifactorial valvular heart disease influenced by both environmental and genetic factors.Lp(a)is an independent risk factor for CAVS and can increase the onset risk of CAVS.Lp(a)plays an important role in the treatment of CAVS.Although surgery is currently the main clinical treatment for CAVS,with further exploration into its pathological mechanism,drug therapy targeting Lp(a)has emerged as a new method.This paper reviews studies about the structure and characteristics of Lp(a),its role in the occurrence and development of CAVS,treatment options related to hyperlipoprotein Aemia,and the studies preventing and treating CAVS by combating inflammation,and enhances the clinicians'understanding and awareness of hyperlipoprotein Aemia and provides new insights for the prevention and targeted drug therapy of CAVS.
