Vascular hypo-reactivity plays a critical role inducing organ injury during hemorrhagic shock. 17β-estradiol (E2) can induce vasodilation to increase blood flow in various vascular beds. This study observed whether E2 restore induced by shock, and effects are associated with RhoA-Rho kinase (ROCK)-myosin light chain phosphatase (MLCP) pathway. The shock model (40 ± 2 mm Hg for 1 h, resuscitation 4 h) was established ovary intact sham operation (OVI), ovariectomized (OVX), OVX plus supplement...

To investigate the effect of mesenteric lymph drainage on spleen injury and expressions inflammatory cytokines in splenic tissue mice following hemorrhagic shock.Male C57 were randomly divided into sham shock, shock shock+drainage groups. The both groups suffered femoral artery bleeding, maintained mean arterial pressure (MAP) 40±2 mmHg for 90 min, resuscitated. And was performed group at time resuscitation. After three hours resuscitation, tissues harvested histological observation protein...

The neutrophil-to-lymphocyte ratio (NLR) is a marker of inflammation that can be obtained quickly, conveniently, and cheaply from blood samples. However, there no research to explore the effects sex age on relationship between NLR mild cognitive impairment (MCI) in community-dwelling older adults.A total 3,126 individuals aged over 60 years Shanghai were recruited for face-to-face interviews, samples collected. MCI was assessed by Mini-Mental State Examination (MMSE) Instrumental Activities...

Abstract Context Advanced glycation end products (AGEs) are a group of molecules formed through nonenzymatic reactions. These compounds associated with several age-related diseases, including sarcopenia and osteoporosis. Objective This work aimed to investigate the relationships between AGEs, osteoporosis, in community-dwelling older adults. Methods cross-sectional study included 1991 adults aged 72.37 ± 5.90 years from China. AGE levels were measured by Reader device. Bone mineral density...

Purpose Post hemorrhagic shock mesenteric lymph (PHSML) return contributes to CD4 + T cell dysfunction, which leads immune dysfunction and uncontrolled inflammatory response. Tumor necrosis factor α induced protein 8 like-2 (TIPE2) is one of the essential proteins maintain homeostasis. This study investigated role TIPE2 in regulation lymphocyte function interaction PHSML TLR2/TLR4. Methods The splenic cells were isolated from various mice (WT, TLR2 -/- , TLR4 ) by immunomagnetic beads,...

Hemorrhagic shock is associated with activation of renin-angiotensin system (RAS) and endoplasmic reticulum stress (ERS). Previous studies demonstrated that central RAS produced by various challenges sensitizes angiotensin (Ang) II-elicited hypertension ERS contributes to the development neurogenic hypertension. The present study investigated whether controlled hemorrhage could sensitize Ang brain mediate this sensitization. Results showed hemorrhaged (HEM) rats had a significantly enhanced...

Severe hemorrhage-induced acute lung injury (ALI) remains the major contributor to critical patient mortality and is associated with posthemorrhagic shock mesenteric lymph (PHSML) return. Omega-3 polyunsaturated fatty acids (ω-3 PUFAs) play overall protection on hemorrhage, but a reliable mechanism needs be identified. The aims of this study were investigate role ω-3 PUFAs in alleviating ALI whether related endotoxin contained PHSML. Mesenteric was harvested from rats subjected hemorrhagic...
