ABSTRACT
Objective:To establish a multicriteria value assessment index system, so as to provide reference for hospitals access of medical consumables.Methods:In May 2021, based on the paper previously published, the expert consultation method was used to finalize the index structure, index definitions and scoring standards, along with an importance grading of the indexes. And the index weights were calculated using the analytical hierarchy process. Then the assessment scale was designed by way of multi-criteria decision analysis and mini-HTA. With the linear cutting stapler used as an example, six clinicians, three hospital administrators and the medical consumable management committee made an empirical analysis and evaluation of its general value. The coefficient of variation and Kendall coefficient of concordance were used to test the consistency of clinicians′ scores.Results:Three rounds of expert consultations finalized an index structure with 4 level-1 and 11 level-2 indexes, and on such basis a multicriteria value assessment index system for hospital access of medical consumables was established. This system comprised the clinician evaluation scale, hospital administrator evaluation scale and medical consumable management committee evaluation scale. The first two of which were used for preliminary screening, and the third for a full-scale, detailed and quantitative evaluation of those selected, hence a decision was made in the end according to the weighted sum of the three scales. This scale system was used to evaluate a foreign brand and a domestic brand of linear cutting staplers, while the former and the latter scored 90.5 and 75.4 respectively. Statistical analysis of the six clinicians found a coefficient of variation CV<0.25, and the Kendall coefficient of concordance W=0.833, proving good consistency of the evaluation criteria and results. Conclusions:The multicriteria value assessment index system proves highly scientific, comprehensive and practicable, serving a good reference for hospitals to build their value-based mechanism to select medical consumables.
ABSTRACT
Objective:To explore the protective effect of the water-soluble total flavonoids from Isodon lophanthoides var.gerardia-nus (Benth.) H.Hara on LO2 cells damage.Methods:The cytotoxicity was evaluated by MTT cell viability determination to confirm the concentration range .Hepatocyte damage model was established by H 2 O2 treatment.After the oxidative stress hepatocyte was coin-cubated with WSTF at different concentrations for various times , the protective effect of WSTF on H 2 O2-induced hepatocyte damage was evaluated by MTT cell viability determination and the content determination of ALT , AST and MDA in cell supernatant .The inhibition of WSTF against H 2 O2-induced LO2 cells apoptosis was evaluated by the quantitative determination of Rhodamine 123 fluorescence and intracellular ROS.Results:The LO2 cells injured by 0.3 mmol· L-1 H2 O2 treatment for 4 h were used as the hepatocyte damage model.The concentration range of WSTF was 0.0312-0.125 mg· ml-1.WSTF could inhibit H2O2-induced injury in LO2 cells and obviously reduce ALT, AST and MDA.Moreover, WSTF could reverse mitochondrial membrane potential depolarization and decrease the amount of intracellular ROS .Conclusion:WSTF exhibits notable protective and curative effects on hepatocyte damage in vitro.
ABSTRACT
Objective To evaluate the association between vitamin D (VD) and vascular endothelial injury in hypertensive patients.Methods Ninety nine patients with hypertension and 126 healthy subjects (control group) from the same community in Nanjing were recruited in the study.The serum levels of fasting blood glucose (GLU),total cholesterol (TC),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG) were measured.Serum 25-hydroxy vitamin D (25-OH-D) and nitric oxide (NO) levels were determined by enzyme-linked immunosorbent assay.The level of plasma endothelial microparticles was measured by flow cytometry.The data were statistically analyzed with SPSS version 19.O.Results The serum 25-(OH)-D [(55.22 ± 11.92) nmol/L vs.(64.17 ± 21.52) nmol/L,t =-3.71],vitamin D binding protein (VDBP) [(257.32 ±141.31) ng/mlvs.(314.21±124.13) ng/ml,t=-3.21],NO levels [(39.35±13.33)μmol/L vs.(43.42 ± 11.83) μmol/L,t =-2.42] in hypertension group were significantly lower than those in control group.And the circulating endothelial cell particles (4.95 ± 1.78 vs.2.84 ± 2.07,t =8.05) in hypertension group was significantly higher than that in control group.In hypertensive patients,the circulating endothelial cell particles in VD deficiency group was significantly higher than that in low VD group and normal VD group [(6.42 ± 1.25)％ vs.(4.6 ± 1.68)％,(3.15 ±0.90)％,F =15.08].And the serum NO level in VD deficiency group was significantly lower than that in other two groups [(36.57 ± 10.52) μmol/L vs.(39.77 ± 13.01) μmol/L,(46.26 ± 25.90) mol/L,F =1.20].Multiple linear regression analysis showed that low serum 25 (OH) D(B =-0.189,SE =0.033,β =0.509,t =-5.72) and gender (B =-0.682,SE =0.351,β =-0.182,t =-2.054) were the risk factors of vascular endothelial injury.Conclusion The serum vitamin D levels in hypertensive patients is decreased,and vitamin D deficiency may be a risk factor for endothelial injury in hypertension.
ABSTRACT
Objective To investigate the prevalence of anxiety and depression in elderly patients with metabolic syndrome (MS) and its related factors.Methods A total of 672 subjects aged 60 or over undergoing health check-up in two Nanjing community health service centers from November 2015 to October 2016 were enrolled in the study.The basic information and the history of hyperlipidemia,hypertension and diabetes were collected by questionnaire survey;the results of physical examination and biochemical testing were documented.The prevalence of anxiety and depression were investigated by the Hospital Anxiety and Depression Scale (HADS).According to MS diagnostic criteria,the subjects were divided into MS group (n=181) and non-MS group (n=491).The HADS scores of two groups were compared and the influencing factors related to anxiety and depression were analyzed.Results The levels of systolic blood pressure (SBP),diastolic blood pressure (DBP),body mass index(BMI),levels of fasting blood glucose (FBG),triglyceride (TG),low density lipoprotein cholesterol (LDL-C) were higher and high density lipoprotein cholesterol (HDL-C) was lower in MS group than those in non-MS group (all P<0.05).The prevalence rates of anxiety and depression in MS group (30.9% and 34.8%) were significantly higher than those in non-MS group (20.2% vs.25.1%,χ2=8.655,6.288,P=0.003,0.012).Multivariate logistic regression analysis showed that obesity (BMI≥28 kg/m2),high FBG (≥7.0 mmol/L),hypertension [blood Pressure≥140/90 mmHg (1 mmHg=0.133 kPa)] were the independent risk factors for anxiety in MS patients (OR=3.987,2.827,2.375,respectively,all P<0.05);obesity (BMI≥28 kg/m2),high FBG(≥7.0 mmol/L),smoke,high TC (≥5.2 mmol/L),hypertension (≥140/90 mmHg) were the independent risk factors for depression in MS patients (OR=7.718,3.233,2.071,1.932,1.910,respectively,all P<0.05).Conclusion Elderly patients with metabolic syndrome are prone to anxiety and depression,and obesity,high FBG,hypertension and other factors are the risk factors for anxiety and depression.
ABSTRACT
Objective To investigate the correlation between serum biochemical parameters and Parkinson's disease (PD) risk in the elderly.Methods The 277 inpatients with PD as PD group in Jiangsu Province Hospital from January 2009 to December 2013 were selected,at the same time,the 277 age and gender-matched healthy persons were enrolled as control group.The levels of total cholesterol (TG),total bilirubin (TB),uric acid (UA),low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were detected and compared between the two groups.Results The levels of TG,UA,TB,HDL-C and LDL-C were significantly lower in PD group than in control group [(4.35±1.13) mmol/L vs.(4.95±0.98) mmol/L,t=6.63;(278.00± 101.89)μmol/L vs.(380.90 ± 108.28) μmol/L,t =12.44;(13.02 ± 7.56) μmol/L vs.(17.39 ± 7.30)μmol/L,t=7.09;(1.26±0.37) mmol/L vs.(1.34±0.28) mmol/L,t=3.38;(2.59±0.79) mmol/L vs.(3.17±0.91) mmol/L,t=7.42,all P＜0.05].Logistic multiple regression analysis showed that the decreased levels of TB,UA and LDL-C were independently associated with prevalence risk of PD (OR=0.940,0.991 and 0.219,all P＜0.001).The combined score of TB,UA and LDL-C was constructed by using the linear weighted method.ROC curve was drawn to select the higher diagnostic validity index among TB,UA,LDL-C and combined score.The area under the ROC curve for TB,UA,LDL-C and combined score was 0.713,0.765,0.682 and 0.809 (all P＜0.001),and the value of combined score was the highest.Conclusions The decreased levels of TB,UA and LDL-C are independently associated with PD.They possess certain clinical value in evaluating the prevalence risk of PD.
ABSTRACT
Objective:To study the expression and correlation of tumor-associated macrophages(TAM) and CCL5 in ganstric cancer.Methods:48 cases patients with completed clinical and pathological data of gastric cancer paraffin block specimens were select-ed.Cancer tissues and adjacent tissues were used as control,using SP immunohistochemical method to detect CD68 and CCL5 in gastric cancer tissues and adjacent tissues,and using the Spearman correlation statistics statistical methods for the correlation.Results:CD68 and CCL5 showed positive expression in gastric cancer tissue,significantly higher than those in the adjacent tissues(P<0.01),CD68 and CCL5 were related with gastric cancer invasion depth, lymph node metastasis, TNM stage and tumor differentiation ( P<0.001 ) . There was positive relation between the expression of CD68 and CCL5 in gastric cancer(P<0.01,r=0.759).Conclusion: CD68 and CCL5 played a driving role to the invasion and metastasis of gastric cancer occurrence,suggesting that the secretion CCL5 by TAM may promote the invasion and metastasis of gastric cancer.
ABSTRACT
Objective:To observe the changes of blood glucose,insulin and dipeptidyl peptidase-Ⅳ(DPP-Ⅳ/CD26)on type 2 diabetes mellitus in rabbits after HUCBSC( human umbilical cord blood stem cells) transplantation. Methods:18 rabbits were randomly divided into normal control group (6 rats,Group C) and diabetic model group (12 rats). After preparation model of type 2 diabetes,and 6 rats of them were treated with HUCBSC ( CD45+,CD34-) transplantation by ear vein transfusion ( Group A) ,and 6 rats were treated with PBS(Group B). All three groups of rabbits were fed for 4 weeks,and the blood glucose was monitored every day,and the level of blood insulin and DPP-IV/CD26 were measured every week. Results:The negative expression rate of CD34 in HUCBSC was 96. 5%. The positive expression rate of CD45 in HUCBSC was 100%. Compared with non transplantation group,the blood glucose and DPP-IV/CD26 in the umbilical cord blood stem cell transplantation group were gradually decreased,and insulin level was gradually increased, the difference was statistically significant (P<0. 01). Conclusion:HUCBSC were round or oval,with adherent growth,HUCBSC trans-plantation can significantly reduce blood glucose, increase insulin secretion, reduce the level of DPP-IV/CD26, the immunological phenotype of HUCBSC was CD45+,CD34-,thus providing a new theoretical basis for the clinical treatment of diabetes and its complica-tions.
