ABSTRACT
Objective To explore the impact of nurse-led multidisciplinary collaborative nutrition inter-vention on the nutritional indicators in the patients with stroke.Methods A total of 100 patients with stroke admitted in this hospital from January to December 2020 were selected as the study subjects and divided into the observation group and control group by the propensity score matching,50 cases in each group.The control group was given the traditional nutrition intervention,and the observation group was given the nurse-led mul-tidisciplinary cooperative nutrition intervention.The blood,nutritional and biochemical indicators,physique monitoring indicators and nutritional risk indicators were compared between the two groups.Results The levels of total protein(TP),albumin(ALB),hemoglobin(Hb),prealbumin(PAB),body mass index(BMI),upper arm muscle circumference(AMC)and triceps skin fold thickness(TSF)on 21 d after admission in both groups were increased compared with those on 2,15 d after admission,and which on 15 d after admission were higher than those on 2 d after admission(P＜0.05),moreover the above indicators levels on 15,21 d after ad-mission in the observation group were higher than those in the control group,and the differences were statisti-cally significant(P＜0.05).Body mass index(BMI),upper arm circumference(AMC)and triceps skinfold thickness(TSF)in both groups on 21 d of admission were higher than those on 2,15 d of admission(P＜0.05).The nutritional risk screening 2002(NRS2002)score on 21 d after admission in the two groups were decreased compared with those on 2,15 d after admission,while which on 15 d after admission was decreased compared with that on 2 d after admission,moreover the NRS2002 score on 15,21 d after admission in the ob-servation group were lower than those in the control group,and the differences were statistically significant(P＜0.05).Conclusion Giving the nurse-led multidisciplinary cooperative nutrition intervention could im-prove the blood nutritional and biochemical indicators and physique monitoring indicators,and reduce the nu-tritional risk of the patients with stroke.
ABSTRACT
Objective To investigate whether the pituitary tumor transformation gene 1(PTTG 1)plays a role in colitis by regulating intestinal epithelial cells pyroptosis.Methods Ten PTTG 1 wild-type(WT)mice and Ten PTTG 1 knockout(KO)mice were randomly divided into 4 groups of 5 each,respectively PTTG1 WT control and experimental group,PTTG1 KO control and experimental group.The mice in the experimental group were given 3%dextran sodium sulfate(DSS)for 6 days to induce acute colitis,and the control group was given sterile double distilled water(ddH2O).The disease activity index of the respective group of mice was observed and recorded.Mouse colonic tissue were collected,and the expression levels of NLRP3,ASC,and GSDMD were determined by immuno-histochemistry and western blot.In HCoEpiC,PTTG1 expression was knocked down using shRNA,and the cells were subsequently treated with TNF-α to induce inflammation.Then,the expression of GSDMD was detected.Results The expression of PTTG1 was decreased in colonic mucosal tissue in mice with acute colitis(P<0.01).Compared with WT mice,the colitis was significantly aggravated in PTTG1 KO mice after 3%DSS treatment.The expression of pyroptosis-related proteins was significantly up-regulated in the colon mucosal tissues of PTTG1 KO experimental mice(P<0.05).After knocking down the expression of PTTG1 in HCoEpiC and TNF-α treatment,the expression levels of GSDMD were significantly up-regulated(P<0.05).Conclusion PTTG1 reduced pyroptosis in intestinal epithelial cells(IECs),while PTTG1 loss can enhance IEC pyroptosis,aggravating colonic inflammation.
ABSTRACT
BACKGROUND:Our previous studies found that adding barium sulfate could improve the mechanical and radiopaque properties of calcium phosphate cement.However,with the degradation of calcium phosphate,the remaining radiopaque agent is difficult to degrade,and the space-occupying and osteoclast effects at the implantation site affect the bone repair process.Therefore,it is necessary to develop a new biodegradable radiopaque material. OBJECTIVE:To discuss the radiopaque ability of bioactive degradable material strontium polyphosphate(SrPP)and its impact on the physicochemical properties and osteogenic effect of calcium phosphate cement. METHODS:(1)Calcium phosphate cement(CPC),starch modified calcium phosphate cement(CPS)and starch modified calcium phosphate cement(20%SrPP-CPN)containing SrPP(20%mass fraction of bone cement powder)were prepared respectively,and the physicochemical properties of the three groups of bone cements were characterized.(2)The three groups of bone cement extracts were co-cultured with rat bone marrow mesenchymal stem cells,respectively,to detect cell proliferation,energy metabolism,and osteogenic differentiation.(3)Bone defects with a diameter of 5 mm were made on each side of the top of the skull of 24 SD rats,and they were randomly divided into control group(without any intervention),CPC group,CPS group,and 20%SrPP-CPN group for intervention,with 6 rats in each group.Relevant tests were performed after 4 and 12 weeks of intervention. RESULTS AND CONCLUSION:(1)Compared with the other two groups of bone cement,20%SrPP-CPN had enhanced radiopaque ability,increased compressive strength and degradation rate,and prolonged curing time,and 20%SrPP-CPN could release Sr2+ stably during degradation.(2)CCK-8 assay showed that 20%SrPP-CPN did not affect the proliferation of bone marrow mesenchymal stem cells.Cell starvation test(serum-free culture)showed that 20%SrPP-CPN could promote the proliferation of bone marrow mesenchymal stem cells compared with the other two groups of bone cement.Compared with the other two groups of bone cements,20%SrPP-CPN increased adenosine triphosphate concentration in bone marrow mesenchymal stem cells.Alkaline phosphatase and alizarin red staining showed that 20%SrPP-CPN could promote osteogenic differentiation of bone marrow mesenchymal stem cells compared with the other two groups of bone cement.(3)In the rat skull defect experiment,Micro-CT scanning and histological observation(hematoxylin-eosin and Masson stainings)showed that bone cement in 20%SrPP-CPN group was significantly degraded compared with that in CPC and CPS groups,and a large number of new bone tissues were dispersed in degraded bone cement.Immunohistochemical staining showed that Runx2 protein expression was increased in 20%SrPP-CPN group compared with CPC group and CPS group(P＜0.01).(4)These results show that 20%SrPP-CPN has good radiopaque ability and osteogenic properties.
ABSTRACT
Objective:To explore the prognostic value of baseline 18F-FDG PET/CT metabolic parameters in locally advanced cervical cancer (LACC) after concurrent chemoradiotherapy (CCRT). Methods:From September 2015 to October 2021, the clinical data of 180 LACC patients (age: 22-76 years) who underwent 18F-FDG PET/CT before CCRT at Affiliated Cancer Hospital of Shandong First Medical University were analyzed retrospectively. The metabolic tumor volume (MTV), total lesion glycolysis (TLG), SUV max, and SUV mean were computed by using the margin threshold of 42%SUV max. The optimal threshold for predicting progression-free survival (PFS) was obtained by ROC curve analysis. The Kaplan-Meier method was applied for survival analysis, and the log-rank test was applied to compare the survival rate between groups. Multivariate Cox proportional hazard regression was used to analyze progression for PFS. Results:The median follow-up was 19.1 months, and 54 patients (30.0%, 54/180) suffered from disease progression. ROC curve analysis showed that the optimal cut-off value of MTV was 31.145 ml, with the AUC of 0.641. Para-aortic lymph node (PALN) metastasis had the highest AUC value (0.589) among the clinical factors, followed by International Federation of Gynecology and Obstetrics (FIGO) stage (0.581). The 1-year PFS rates of patients with MTV<31.145 ml ( n=88) and MTV≥31.145 ml ( n=92) were 80.68% and 59.78%, respectively ( χ2=13.72, P<0.001). Multivariate Cox analysis demonstrated that pathological type (hazard ratio ( HR)=3.075, 95% CI: 1.370-6.901, P=0.006), FIGO stage ( HR=1.955, 95% CI: 1.031-3.707, P=0.040), PALN metastasis ( HR=2.136, 95% CI: 1.202-3.796, P=0.010) and MTV ( HR=2.449, 95% CI: 1.341-4.471, P=0.004) were the significant predictors for PFS. Conclusions:Pathological type, FIGO stage, PALN metastasis and MTV are independent prognostic risk factors for PFS. MTV as the baseline 18F-FDG PET/CT metabolic parameter, can realize prognostic stratification analysis.
ABSTRACT
Objective:To construct machine learning models based on CT imaging and clinical parameters for predicting progression-free survival (PFS) of locally advanced cervical cancer (LACC) patients after concurrent chemoradiotherapy (CCRT).Methods:Clinical data of 167 LACC patients treated with CCRT at Shandong Cancer Hospital from September 2015 to October 2021 were retrospectively analyzed. All patients were randomly divided into the training and validation cohorts according to the ratio of 7 vs. 3. Clinical features were selected by univariate and multivariate Cox proportional hazards model ( P<0.1). Radiomics models and nomograms were constructed by radiomics features which were selected by least absolute shrinkage and selection operator (LASSO) Cox regression model to predict the 1-, 3- and 5-year PFS. Combined models and nomogram models were developed by selected clinical and radiomics features. The Kaplan Meier-curve, receiver operating characteristic (ROC) curve, C-index and calibration curve were used to evaluate the model performance. Results:A total of 1 409 radiomics features were extracted based on the region of interest (ROI) in CT images. CT radiomics models showed better performance for predicting 1-, 3-and 5-year PFS than the clinical model in the training and validation cohorts. The combined model displayed the optimal performance in predicting 1-, 3-and 5-year PFS in the training cohort [area under the curve (AUC): 0.760, 0.648, 0.661, C-index: 0.740, 0.667, 0.709] and verification cohort (AUC: 0.763, 0.677, 0.648, C-index: 0.748, 0.668, 0.678).Conclusions:Combined model constructed based on CT radiomics and clinical features yield better prediction performance than that based on radiomics or clinical features alone. As an objective image analysis approach, it possesses high prediction efficiency for PFS of LACC patients after CCRT, which can provide reference for clinical decision-making.
ABSTRACT
Acute kidney injury (AKI) is an important factor for the occurrence and development of CKD. The protective effect of dihydroartemisinin on AKI and and reported mechanism have not been reported. In this study, we used two animal models including ischemia-reperfusion and UUO, as well as a high-glucose-stimulated HK-2 cell model, to evaluate the protective effect of dihydroartemisinin on premature senescence of renal tubular epithelial cells in vitro and in vivo. We demonstrated that dihydroartemisinin improved renal aging and renal injury by activating autophagy. In addition, we found that co-treatment with chloroquine, an autophagy inhibitor, abolished the anti-renal aging effect of dihydroartemisinin in vitro. These findings suggested that activation of autophagy/elimination of senescent cell might be a useful strategy to prevent AKI/UUO induced renal tubular senescence and fibrosis.

Primary lung cancer is the first malignant tumor in our country and in the world with an increasing mortality trend, which seriously endangers the human health. By digging the deep relationship between high-dimensional imaging features and pathophysiological features, radiomics can establish a predictive model to distinguish pathological types, tumor stages, distant metastases and survival, guide individualized diagnosis and treatment strategies, and improve prognosis. PET/CT has higher diagnostic accuracy and specificity by reflecting tumor tissue metabolism. This article reviews the application of PET/CT radiomics in the treatment of non-small-cell lung cancer (NSCLC).
ABSTRACT
Objective:To evaluate the competence of head nurses by using the in-basket test for establishing a hierarchical training system for these nurses.Methods:A set of in-basket test was independently designed to evaluate the head nurses of a tertiary hospital in September 2021.Fourteen competency indicators, including positive initiative, coordination and communication ability, and leadership, problem solving ability, motivation, empowerment, attention to quality and order, etc, were selected to analyze the answers of the in-basket test and score their competency level. The measures were described by Mean±SD and M(IQR), and the counts were described by rates and percentages. The rank sum test and multiple linear regression were used to analyze the influencing factors of competency scoring of head nurses. Results:A total of 133 head nurses were tested, with a total competency scoring of 30.0(5.5). The highest indicators were talent cultivation 3.0(2.0), positive initiative 3.0(1.0), coordination and communication ability 3.0(1.0), while those with lower scores were empowerment 1.0(1.0) and motivation 1.5(1.5). The rank sum test analysis showed that age, position, job position character and working seniority were the influencing factors of competency score( P<0.05). The multiple linear regression analysis showed that, working seniorities of 16-20 years( β=0.583, P=0.013), 21-25 years( β=0.732, P=0.008), 26-30 years( β=0.632, P=0.026) were the influencing factors of competency score of head nurses. Conclusions:The in-basket test is practical to evaluate the competence of head nurses as a basis for their targeted training in the future.
ABSTRACT
Objective:To evaluate the value of ultrasonography in evaluating the influential factors of early insufficient flow after central venous catheter placement in dialysis patients.Methods:Three hundred and twenty seven hemodialysis patients who underwent central venous catheterization at the Affiliated Hospital of Chengde Medical College from May 2016 to June 2019 were selected. According to the catheter flow, the patients were divided into the low catheter flow group(43 cases) and the normal catheter flow group(284 cases). The distribution variance of clinical features(age, gender, blood pressure) were compared and whether some ultrasonic parameters(position of catheter tip, left ventricular ejection fraction, left atrial end-systolic diameter, left ventricular end-diastolic diameter, distance from the catheter tip to superior vena cava beyond right atrial opening) had influence on the insufficient catheter flow in the early stage between the two groups were analyzed.Results:The differences of left ventricular ejection fraction, left atrial end-systolic diameter and position of catheter tip between the two groups were statistically different( P<0.05). However, univariate and multivariate analyses showed that there were significant differences in catheter tip approaches and touches the wall of right atrium( OR=5.393, 95% CI=2.039-14.263, P=0.001), increased left atrial end-systolic diameter( OR=0.321, 95% CI=0.124-0.827, P=0.019), left ventricular ejection fraction in critical range( OR=2.953, 95% CI=1.113-7.835, P=0.030) and decreased left ventricular ejection fraction( OR=5.828, 95% CI=1.869-18.174, P=0.002) were the independent risk factors of early insufficient catheter flow. Conclusions:Insufficient catheter flow after central venous catheterization is related to catheter position, left atrial end-systolic diameter and left ventricular ejection fraction. Ultrasonography evaluation is a primary method to observe the position of the catheter tip in dialysis patients and diagnose the early insufficient catheter flow after central venous catheterization.
ABSTRACT
Objective To verify whether β-arrestin-2 inhibits autophagy by up-regulating PI3K/Akt signal to protect the liver from ischemia-reperfusion injury (IRI) in mice. Methods Twelve β-arrestin-2 knockout (KO) and twelve wild-type (WT) C57BL/6 mice were randomly divided into the KO+sham group, KO+IRI group, WT+sham group and WT+IRI group, six mice in each group. The mouse models with 70% liver IRI were established or sham operation was performed. Relevant experiments were carried out at 6 h after liver reperfusion or operation. The expression levels of apoptosis signal protein cleaved Caspase-3, proliferation signal protein Ki-67 and the PI3K/Akt signal protein p-Akt were detected by immunohistochemical staining. Results Immunohistochemical staining demonstrated that compared with the corresponding sham group, the positive cell count for cleaved Caspase-3, Ki-67 and p-Akt in liver tissues of mice was significantly increased in the KO+IRI and WT+IRI groups (all P < 0.01). Compared with the WT+IRI group, the positive cell count for cleaved Caspase-3 in liver tissues of mice was significantly increased, whereas the positive cell count forKi-67 and p-Akt was significantly decreased in the KO+IRI group (both P < 0.05). Conclusions β-arrestin-2 can mitigate the liver cell apoptosis and promote the repair of injury after IRI in mice. Moreover, β-arrestin-2 inhibits autophagy by up-regulating the PI3K/Akt signal to alleviate liver IRI in mice.
ABSTRACT
Objective To investigate characteristics of deceleration capacity (DC) and Tp-e/QT value in different age groups of patients with diabetic autonomic neuropathy, and to analyze their influencing factors. Methods A total of 487 subjects were enrolled in this study, and divided into three groups:patients with diabetic autonomic neuropathy (DM+CAN group,n=287), normal glucose tolerance patients with diabetic autonomic neuropathy (CAN group,n=130) and healthy controls (NC group,n=150).Then the DM+CAN group were further divided into three subgroups according to age tertiles:the lowest tertile group (35.0~47.2 years old,n=91),the middle tertile group (47.3~59.6 years old,n=116)and the highest tertile group (59.7~72.0 years old,n=80).All subjects were underwent 24-hour dynamic electrocardiogram recordings.DC and Tp-e/QT values were calculated,and then the correlation between DC and Tp-e/QT with other indicators was analyzed. Results The levels of WC,SBP,BMI,FPG,HbA1c,FIns and HOMA-IR were higher in DM+CAN group than in CAN group and in NC group (P0.05).DC increased [(2.90±0.47) vs (4.22±0.41) vs (4.97±0.35) ms],and the Tp-e/QT decreased [(0.23±0.05) vs (0.18±0.03) vs (0.12±0.02)] from the highest tertile group to the lowest tertile group,(P<0.05 or P<0.01),and the pairwise comparisons were statistically significant (P<0.05 or P<0.01).Multiple stepwise regression analysis showed that age,DM duration,WC,FPG,HbA1c,complicated with hypertension and coronary heart disease (CHD) were risk factors for DC and Tp-e/QT values (P<0.05). Conclusion Together with the increased age,DC level is reduced and Tp-e/QT value increased in patients with diabetic autonomic neuropathy.Dynamic electrocardiogram should be considered in patients with advanced age,long DM duration,high level of WC,FPG,HbA1c,and complicated with hypertension and CHD,in order to prevent the occurrence of cardiovascular events effectively.
ABSTRACT
prognosis of patients with acute upper gastrointestinal bleeding (AUGIB). Methods A total of 130 patients with AUGIB in our hospital were enrolled in this study from August 2014 to August 2016 . Three kinds of scoring systems including Rockall, Blatchford and AIMS65 were used to evaluate the risk classification of the patients. Patients were followed up for 2 months. The incidence rates of re-bleeding and death within 2 months after admission were observed. Data of prognosis in patients with AUGIB were compared between the three scoring systems in the prognosis of patients with AUGIB, including the risk classification and the prediction accuracy of re-bleeding and death. Results There were no significant differences in the re-bleeding rate and fatality rate between the groups divided by Rockall and Blatchford scoring systems ( P>0.05). According to the grouping results of AIMS65 scoring system, the re-bleeding rate of low-risk group was lower than that in high risk group (1.45%vs. 13.11%, P=0.01), but there was no significant difference in fatality rate between the two groups (P>0.05). The values of area under the curve (AUC) of predicting re-bleeding rates by using Rockall, Blatchford and AIMS65 scoring systems were 0.6258, 0.6910, and 0.7241, and the values of AUC of predicting fatality rates were 0.7031, 0.7969, and 0.7031 by using receiver operating characteristic curve (ROC) analysis. There were no significant differences between them (P>0.05). The values of AUC of predicting re-bleeding rates by using the risk grading calculation by Rockall, Blatchford and AIMS65 scoring systems were 0.6189, 0.6139 and 0.7254 (P>0.05). But the values of AUC of predicting fatality rates were 0.6211, 0.6641 and 0.7695 (P<0.01). Conclusion The operation method of AIMS65 scoring system is simple and convenient, which is applicable to a wide range of patients with AUGIB. In the prediction of re-bleeding and mortality, AIMS65 scoring system has high accuracy and stability, which is worthy of promoting in clinical application.
