Objective To investigate the relationship between carotid artery intima-media thickness and renal function in patients with diabetes mellitus.Methods 424 patients of type 2 diabetes without dialysis were enrolled in a cross-sectional study.According to their artery intima-media thickness (IMT),the patients were divided into normal group and higher IMT group.All patients according to UAER or 24h urinary protein were divided into normal proteinuria group,micro-proteinuria group and clinical proteinuria group.The biochemical examination,eGFR,and atherosclerotic plaque of different groups were compared.Pearson or spearman correlation was used to analyze the relationship between eGFR,IMT and other parameters.Risk factors for eGFR decline were analyzed by binary logistic regression.Results Compared with normal group,patients in the higher IMT group were older [(63.3±10.2) year vs (52.5 ± 10.6) year,P ＜ 0.05],and underwent longer duration of diabetes [(8.9±6.7) year vs (6.2±5.7) year,P ＜ 0.05].Their level of eGFR was decreased [(75.92±28.00) ml/min vs (91.64±24.05) ml/ min,P ＜ 0.05],while plaque incidence (71.3％ vs 18.3％,x2=112.42,P ＜ 0.01) and prevalence of hypertension (56.4％ vs 29.6％,x2=27.22,P ＜ 0.01) increased.Correlation analysis showed that IMT was positively correlated with age (r=0.503,P ＜ 0.01),duration of diabetes (r=0.204,P ＜ 0.01),24 h urine protein (rs=0.175,P ＜ 0.05),plaque (rs=0.562,P ＜ 0.01),and hypertension (rs=0.193,P ＜ 0.01),but negatively correlated with eGFR (r=-0.307,P ＜ 0.01).Logistic regression analysis showed that age,serum uric acid,24 h urine protein and carotid artery intima-media thickness were independent risk factors for eGFR decline [OR=1.115,95％CI(1.053,1.165),P ＜ 0.001;OR=1.008,95％CI (1.002,1.014),P=0.006;OR=1.492,95％ CI(1.170,1.903),P=0.001;OR=1.619,95％ CI(1.121,2.339),P=0.010].Conclusion Carotid artery intima-media thickness is an independent risk factor for kidney function decline in patients of diabetes.

Objective Cellular response to estradiol is mediated both by estrogen receptor (ER) binding to estrogen response element (ERE) and by non-nuclear actions like activation of signal transduction pathways such as mitogen activated protein kinase (MAPK) pathway. However, the signal transduction of estrogen involving phosphatidylinositol 3-kinase-protein kinase B (PI3K -PKB) is not clear in endometrial carcinoma. Our purpose was to study if PI3K-PKB signaling pathway could be activated rapidly by 17?-E 2 through non-nuclear action and also, whether PI3K inhibitor, LY294002, could inhibit such non-nuclear action of 17?-E 2 in endometrial carcinoma cell line Ishikawa. Methods Levels of phosphorylated PKB(Ser473 site, p-PKB) and total PKB were examined by western blotting in Ishikawa cells after stimulation with 17?-E 2 at 1?10 -6 mol/L for different time periods and at varied doses for 30 min. Optimal time and appropriate dose for 17?-E 2 to activate PKB in Ishikawa cells were observed. Inhibitory effect of LY294002 on activation of PKB induced by 17?-E 2 was also studied. p-PKB/PKB ratio was used to indicate levels of activation of PKB. Results p-PKB/PKB at 15 min (0.533?0.029) was significantly higher than the control (0.361?0.029, P 0.05, 0.05,

Objective To investigate the expression and clinical significance of serum microRNA (miRNA) expression profiling in the occurrence and progression of diabetic nephropathy.Methods The miRNA expression profiling was detected by miRNA TaqMan Low Density Array chip from 10 patient with diabetic nephropathy,10 diabetes patients with normoalbuminuria and 10 health control.Real-time quantitative PCR was applied to verify the result of miRNA array in serum samples of 66 patients with diabetic nephropathy (36 patients with microalbuminuria,30 patients with macroalbuminuria),40 diabetes patients with normoalbuminuria and 40 health control.And the relationship of differetial expression with clinical features was analyzed.Results miR-150-5p,miR-155-5p,miR-30e-5p and miR-3196 being validated by real-time quantitative PCR differentially expressed in 3 groups of serum samples from the diabetes patients with microalbuminuria (n=36),with normoalbuminuria (n=40) and health control (n=40) (P ＜ 0.05).Serum miR-150-5p (P=0.005) and miR-155-5p (P=0.006) changed significantly between diabetes patients with microalbuminuria (n=36) and with macroalbuminuria (n=30).Compared with the diabetes patients with microalbuminuria,serum miR-150-5p and miR-155-5p increased by 2.3 and 1.5 times in macroalbuminuria group,respectively.Estimated glomerular filtration rate and urinary albumin excretion rate significantly correlated with serum miR-150-5p and miR-155-5p level.Conclusions miR-150-5p and miR-155-5p may be involved in the process of pathological mechanisms of diabetic nephropathy.Serum miR-150-5p and miR-155-5p may be regarded as potential biomarkers to diagnosis the occurrence and development of diabetic nephropathy.

Objective To analysis the activity of transcriptional factors in endometrial cancer cell lines with different estrogen receptor subtypes. Methods The mRNA levels of estrogen receptor (ER) was detected by quantitative RT-PCR , and the activity of transcriptional factors was also analysed by 345-channel protein/DNA array in RL-952 ( the expression status of ERα and ERβ both positive), HEC-1A [ERα(±),while ERβ negative] and HEC-1B (ERα and ERβ both negative). The transcription factors of NFkBp65 and p38MAPK with different activity were tested by enzyme-linked immunosorbent assay(ELISA) to confirm the results of protein/DNA array. Results The mRNA levels of ERα in RL-952, HEC-1A and HEC-1B were (6780±282 ), ( 684±84 ) and ( 168±38 ) eopy/ng, respectively. Among 345 candidate transcriptional factors, there were 28 factors associated with ER status. Compared with RL-952 cells, 13 transcriptional activity factors were concomitandy up-regulation, while 15 concomitantly down-regulation in HEC-1A and HEC-1B cells. Transcriptional activities of TrF (1)-1, NRF-1, TCE were significantly correlated with the high-expression status of ERα mRNA ( r =0.523, P=0.037 ), while RFX123 and Ikaros were signitleanfly correlated with the low-expression status of ERα mRNA ( r=-0.312, P=0.041 ). Conclusion Transcriptional factors of TTF(1)-1, NBF-1, TCE may be associated with ER-mediated signal pathway, while RFX123 and Ikaros may be associated with non ER-mediatecl signal pathway in endometrial cancer.

Neoadjuvant chemotherapy can be safely and effectively used in locally advanced rectal cancer.

In recent years, wearable devices have seen a booming development, and the integration of wearable devices with clinical settings is an important direction in the development of wearable devices. The purpose of this study is to establish a prediction model for postoperative pulmonary complications (PPCs) by continuously monitoring respiratory physiological parameters of cardiac valve surgery patients during the preoperative 6-Minute Walk Test (6MWT) with a wearable device. By enrolling 53 patients with cardiac valve diseases in the Department of Cardiovascular Surgery, West China Hospital, Sichuan University, the grouping was based on the presence or absence of PPCs in the postoperative period. The 6MWT continuous respiratory physiological parameters collected by the SensEcho wearable device were analyzed, and the group differences in respiratory parameters and oxygen saturation parameters were calculated, and a prediction model was constructed. The results showed that continuous monitoring of respiratory physiological parameters in 6MWT using a wearable device had a better predictive trend for PPCs in cardiac valve surgery patients, providing a novel reference model for integrating wearable devices with the clinic.

In the past two decades, adult cardiac surgery has developed by leaps and bounds in both anesthetic techniques and surgical methods, whereas the incidence of postoperative pulmonary complications (PPCs) has not changed. Until now PPCs are still the most common complications after cardiac surgery, resulting in poor prognosis, significantly prolonged hospital stays and increased medical costs. With the promotion of the concept of enhanced recovery after surgery (ERAS), pre-rehabilitation has been becoming a basic therapy to prevent postoperative complications. Among them, preoperative inspiratory muscle training as a very potential intervention method has been widely and deeply studied. However, there is still no consensus about the definition and diagnostic criteria of PPCs around the world; and there is significant heterogeneity in preoperative inspiratory muscle training in the prevention of pulmonary complications after cardiac surgery in adults, which impedes its clinical application. This paper reviewed the definition, mechanism, and evaluation tools of PPCs, as well as the role, implementation plan and challenges of preoperative inspiratory muscle training in the prevention of PPCs in patients undergoing cardiac surgery, to provide reference for clinical application.

Objective    To investigate the safety and feasibility of early mobilization in critically ill patients with femoral catheters, and to provide reference for guiding clinical rehabilitation training. Methods    The literature on the safety and feasibility of early mobilization in critically ill patients with femoral catheters included in PubMed, EMbase, OVID, Springer-link, Wiley Online Library, and Web of Science up to June 2021 was searched, and relevant data were extracted for analysis. Results    Seventy-two papers were initially screened, and 12 papers that met the criteria were finally included, covering 1 056 patients, and 489 patients had femoral catheters. Patients underwent 6 495 sessions of physical therapy, and a total of 62 patients had adverse events, including 14 (2.86%, 14/489) patients with catheter-related adverse events. Conclusion    Although early mobilization in critically ill patients with femoral catheters may lead to adverse catheter-related events, the incidence is low. Therefore, the associated risks and benefits should be weighed in clinical practice, and femoral catheter is not recommended as a contraindication for early mobilization in critically ill patients.
