ABSTRACT

Objective:To determine the prevalence of sarcopenia and explore related influencing factors of sarcopenia in maintenance hemodialysis (MHD) patients.Methods:MHD patients aged ≥18 years old and receiving therapies of ≥3 months from March 2019 to December 2019 in Blood Purification Centre of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were retrospectively enrolled in this study. General data of the patients were collected. Grip strength was measured by the Jamar dynamometer and the chair stand was measured by a chair of standard height to assess skeletal muscle strength and appendicular skeletal muscle mass was measured by dual energy X-ray absorptiometry. Baseline data between MHD patients with and without myasthenia were compared. Logistic regression analysis method was used to analyze the influencing factors for sarcopenia in MHD patients.Results:A total of 125 MHD patients were enrolled, with 68 males (54.4%), age of (59.4±14.9) years and median dialysis age of 51.0(23.5, 101.0) months. Sarcopenia was diagnosed in 39 cases (31.2%). Compared with MHD patients without sarcopenia, age, tumor necrosis factor-α, von Willebrand factor (vWF) and proportion of using α ketones were higher, and serum carbondioxide combining power (CO 2CP), prealbumin, albumin and proportion of regular exercise were lower in MHD patients with sarcopenia (all P<0.05). Multivariable logistic regression analysis results showed that low CO 2CP ( OR=0.717, 95% CI 0.576-0.892, P=0.003), high vWF ( OR=1.037, 95% CI 1.016-1.058, P<0.001) and no regular exercise ( OR=0.309, 95% CI 0.118-0.810, P=0.017) were independent influencing factors of sarcopenia in MHD patients. Conclusions:The prevalence of sarcopenia in MHD patients is high. Low CO 2CP, high vWF and no regular exercise are independent influencing factors for sarcopenia in MHD patients.

ABSTRACT

Objective To investigate the association between serum 25(OH)D3 and high sensitive C -reac-tive protein (hs-CRP),tumor necrosis factor -alpha (TNF-α),interleukin-6 (IL-6) inflammatory markers in non-obese patients with type 2 diabetes mellitus (T2DM).Methods From June 2015 to September 2015,in this cross-sectional study,120 non-obese patients with T2DM(female in 58 cases,male in 62 cases) in Taiyuan Central Hospital were selected as T2DM group,and 120 non-obese patients with T2DM and 96 healthy subjects ( control group) were recruited.The serum concentrations of glucose,HbA1c,insulin,25( OH) D3 and inflammatory markers including TNF-α,IL-6 and hs-CRP were measured.A homeostatic model of insulin resistance (HOMA-IR) was also evaluated.The clinical and biochemical characteristics of T 2DM were observed in the group of vitamin D deficien-cy group,vitamin D insufficiency group and vitamin D normal group.And the relativities were analyzed between it with hs-CRP,TNF-α,IL-6,HOMA-IR,INF,FBG,BMI,WHR,and so on.The relativities were observed between 25(OH)D3 with all the factors.Results The mean serum concentration of 25(OH)D3 in the non -obese T2DM group was (10.65 ±3.55)ng/mL,which was significantly lower than (18.44 ±5.21)ng/mL in the normal control group (t=-6.84,P =0.012).The levels of serum TNF -αand IL -6 in the T2DM group were (15.51 ± 4.87)ng/L and (18.12 ±4.13) ng/L,respectively,which were significantly higher than those in the control group [(8.99 ±2.54)ng/L,(8.89 ±2.07)ng/L](t=7.95,10.04,P=0.017,0.007).The proportions of deficiency,insufficiency and normal of vitamin D in T2DM patients were 60.83%,31.67%and 7.50%,respectively .The levels of TNF-αand IL-6 in the serum 25(OH) D3 deficiency group were significantly higher than those in the normal 25(OH)D3 group [(17.93 ±4.94)ng/L vs.(10.30 ±4.52)ng/L,F=6.897,P=0.026;(20.14 ±4.99)ng/L vs. (16.39 ±5.06)ng/L,F=10.589,P=0.017].There was a significant correlation between serum 25(OH)D3 and HOMA-IR(r=-0.041;P=0.030),TNF-α(r=-0.229;P=0.040) and IL -6 levels (r=-0.299;P=0.032),but there was no significant correlation with inflammatory factor hs -CRP and fasting blood glucose. Conclusion Vitamin D deficiency is common in patients with T2DM,and systemic chronic inflammation may also play an important role in the pathogenesis of T 2DM.This study shows that vitamin D may play an important role in the pathogenesis of insulin resistance and chronic systemic inflammatory response,an important pathogenesis of T2DM.

ABSTRACT

Objective Recent evidence has implicated Larp1,an RNA-binding protein,in cell motility and EMT therefore prompting the study of Larp1 in EOC.This project aims to examine the potential role of Larp1 in cell invasion.Methods Ovarian cancer cells SKOV-3 and OVCAR-3 were transfected with DNA constructs to overexpress Larp1 and transfect cells were used to assess the overexpression of Larp1 in cell invasion and metastasis using several functional assay.Results Larp1 overexpression in both OVCAR-3 and SKOV-3 cells appear to enhance the invasive ability of cells and the accumulation of Larp 1 in these chemoinvasive protrusions strongly suggests the potential role of Larp1 in invadopodia formation.Cell spot chemoinvasion assay demonstrated increased chemoinvasion of Larp1 overexpressing SKOV-3 and OVCAR-3 cells towards a gradient of TGF-β,EGF and bFGF.Conclusions With its potential role in EMT and cell invasion,a deeper understanding of the physiological role of Larp1 in cancer cell motility will be potentially beneficial in the diagnosis and treatments of ovarian cancer.

ABSTRACT

Objective To explore the normal range of serum uric acid in quails.Method The data were collect-ed from male and female quails of different strains in 11 experiments, and analyzed by the way of medical reference value. Result The mean value of serum uric acid of male Difake strain quails was (221.06 ±79.59)μmol/L,and the normal range was (87.32 to 382.34)μmol/L.The mean value of serum uric acid of female Difake strain quails was (189.85 ± 68.58)μmol/L, and the normal range was ( 72.72 to 369.73 )μmol/L.The mean value of serum uric acid of male Longcheng strain quails was (217.22 ±72.91)μmol/L,and the normal range was (82.92 to 360.24)μmol/L.The mean value of serum uric acid of female Longcheng strain quails was ( 197.27 ±66.84 )μmol/L, and the normal range was (95.36 to 348.73)μmol/L.The serum uric acid value of female quails was significantly lower than that of male quails. There was no significant difference in the value of serum uric acid between female and male quails from each day-age groups.Conclusions This study has established the normal ranges for serum uric acid in quails of different strains and genders.
