Shift work, as a form of non-conventional work schedule, significantly increases the risk of vascular aging and related diseases due to circadian rhythm disruption, sleep disturbances, and unhealthy lifestyle behaviors. This review systematically summarized the mechanisms and epidemiological evidence linking shift work to vascular aging. Available studies indicated that shift work disrupts the rhythmic expression of core circadian clock genes (e.g., BMAL1, CLOCK, PER, CRY), leading to dysregulated glucose and lipid metabolism, enhanced oxidative stress, chronic inflammation, and altered diurnal blood pressure patterns, thereby directly impairing endothelial function and accelerating arterial stiffness. Sleep deprivation and fragmentation further reduce nitric oxide bioavailability and promote endothelin-1 secretion, exacerbating vascular constriction and inflammatory responses. Existing epidemiological data show that shift workers exhibit higher prevalence of hypertension, metabolic syndrome, and atherosclerosis compared with non-shift workers, accompanied by abnormal vascular function indicators such as pulse wave velocity and carotid intima-media thickness. Additionally, unhealthy dietary habits, psychological stress, and sedentary behavior in shift workers synergistically contribute to vascular aging. This review aims to provide a theoretical basis for the pathological link between shift work and vascular aging and to inform public health policy formulation and occupational health management.

Objective To investigate the mechanism by which Yangmai Tongluo formula improves microcirculation disorders induced by high homocysteine(Hcy)levels via regulation of the acid sphingomyelinase(ASM)and endoplasmic reticulum(ER)stress pathways.Methods Fifty male C57BL/6J mice were divided randomly into a control group,Hcy model group,Yangmai Tongluo formula low-/high dose groups(5.3,10.4 g/kg,respectively),and a folic acid group(0.08 g/kg).Except for the control group,microcirculation disorders were induced in all mice using drinking water containing 1.8 g/L Hcy for 6 weeks.After modeling for 2 weeks,mice were administered the corresponding treatments by gavage for 4 weeks.Serum Hey concentrations and the blood perfusion volume of the lower extremity microvessels were measured.Protein expression levels of zonula occludens ZO-1,ZO-2,intercellular adhesion molecule-1(ICAM-1),vascular cell adhesion molecule-1(VCAM-1),ASM,glucose-regulated protein 78(GRP78),and C/EBP homologous protein(CHOP)in the cardiac microvascular endothelium were analyzed using immunofluorescence.Results Serum Hcy levels were significantly increased in the Hcy model group compared with the control group(P<0.05).Yangmai Tongluo formula did not significantly reduce Hey levels compared with the Hey model group,but blood perfusion in the lower extremities was significantly increased(P<0.01)and expression levels of ZO-1 and ZO-2 in the cardiac microvascular endothelium were restored(P<0.001)in the Yangmai Tongluo formula high dose group.It also inhibited the expression of ICAM-1,VCAM-1,ASM,GRP78,and CHOP(P<0.05),with comparable effects to folic acid.Conclusions Yangmai Tongluo formula improves Hcy-induced microcirculation disorders and endothelial dysfunction by inhibiting ASM activity and alleviating ER stress,via a mechanism closely related to the regulation of endothelial inflammation and barrier stability.These result provide experimental evidence to support the use of traditional Chinese medicine to treat microvascular diseases.

Objective:To explore the safety and efficacy of intraosseous regional administration (IORA) of vancomycin for preventing infection in primary total knee arthroplasty (TKA).Methods:A total of 124 patients with knee osteoarthritis undergoing TKA between February 2024 and May 2024 at nine hospitals were enrolled. Preoperative infection prophylaxis involved either IORA (0.5 g vancomycin administered via intraosseous regional infusion before incision) or intravenous infusion (1 g vancomycin via peripheral vein). The IORA group included 15 males and 47 females with a median age of 66.5 years (range, 60.0-70.0 years), while the intravenous group included 14 males and 48 females with a median age of 66.0 years (range, 61.8-70.3 years) years. Intraoperative samples were collected including fat and synovium tissues after incision, before prosthesis placement, and after tourniquet release; distal femoral cancellous bone during femoral osteotomy; proximal tibial cancellous bone during tibial osteotomy; proximal intercondylar cancellous bone before prosthesis placement; and peripheral blood from non-infused arms at surgery initiation and after tourniquet release. Vancomycin concentrations were measured using liquid chromatography-tandem mass spectrometry. Vital sign changes were recorded from admission to 5~10 minutes post-IORA (IORA group) or post-incision (intravenous group). Follow-ups were conducted on postoperative day 1 and 3, and at 1 and 3 months, to document complications including IORA-related adverse events, periprosthetic joint infections, surgical site infections, red man syndrome, acute kidney injury, deep vein thrombosis and so on.Results:Vancomycin concentrations in bone, fat, and synovial tissue samples were significantly higher in the IORA group than in the intravenous group ( P<0.05), while vancomycin concentrations in blood samples were significantly lower in the IORA group than in the intravenous group ( P<0.05). Only 7.3%(41/558) of tissue samples in the IORA group had vancomycin concentrations below 2.0 μg/g (the minimum inhibitory concentration of vancomycin against coagulase-negative staphylococcus), compared to 59.3%(331/558) in the intravenous group (χ 2=11.285, P<0.001). In the intravenous group, 16.9%(21/124) of blood samples had vancomycin concentrations exceeding 15.0 mg/L (the threshold associated with a significantly increased risk of nephrotoxicity), while all concentrations in the IORA group were below this threshold, the difference was statistically significant (χ 2=22.943, P<0.001). There were no statistically significant difference ( P>0.05) in vital signs changes before and after vancomycin administration between the two groups. Two patients in the intravenous group experienced incision exudate, while no other related complications occurred in either group. Conclusions:Compared to the traditional intravenous infusion of 1 g vancomycin, intraosseous injection of a low dose (0.5 g) of vancomycin achieves higher local tissue concentrations in the knee joint with a lower incidence of adverse reactions and is safe for infection prophylaxis. Despite guidelines not recommending the routine use of vancomycin for preventing infection after primary TKA, intraosseous injection of 0.5 g vancomycin may be considered intraoperatively for primary TKA in the following scenarios: patients in medical institutions with a high prevalence of methicillin-resistant staphylococcus aureus (MRSA) infections, patients with potential preoperative MRSA colonization, or patients with cephalosporin allergy.
