RESUMEN
AIM:To establish a nomogram model to predict the effect of serum ferritin on diabetic retinopathy and evaluate the model.METHODS:A total of 21 variables, including ferritin, were screened by univariate and multivariate regression analysis to determine the risk factors of diabetic retinopathy. A nomogram prediction model was established for evaluation and calibration.RESULTS:Ferritin, duration of diabetes, hemoglobin, urine microalbumin, regularity of medication and body mass index were included in the nomogram model. The consistency index of the prediction model with serum ferritin was 0.813(95%CI: 0.748-0.879). The calibration curves of internal and external verification showed good performance, and the probability of the threshold suggested by the decision curve was in the range 10% to 90%. The model had a high net profit value.CONCLUSIONS:Serum ferritin is an important risk factor for diabetic retinopathy. A new nomogram model, which includes body mass index, duration of diabetes, ferritin, hemoglobin, urine microalbumin and regularity of medication, has a high predictive accuracy and could provide early prediction for clinicians.
RESUMEN
Elizabethkingia anophelis is one of the most significant pathogens threatening human health.As an important opportunistic pathogen, it is prone to nosocomial infection outbreaks, and can cause neonatal meningitis, especially in prematurity, seriously affecting the safety and quality of life of children.E.anophelis has the characteristic of multi-drug resistance, which brings great challenges to clinical treatment.E.anophelis was commonly misidentified as E. meningosepticum in previous reports.In fact, E.anophelis accounts for a significant proportion of Elizabethkingia infections, which needs more attention.This article reviews the epidemiology of E. anophelis, clinical features of neonatal infection, drug sensitivity, treatment and prevention, in order to provide reference for clinical diagnosis and treatment.
RESUMEN
The two forms of brain-derived neurotrophic factor (BDNF), mature BDNF (mBDNF) and BDNF precursor (proBDNF), bind to corresponding receptors and mediate a series of biological signals, which play important roles in proliferation, survival and apoptosis. More and more studies have focused on the role of unbalanced transformation from proBDNF to mBDNF in neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease, as well as their potential as biomarkers and treatment targets. This article reviews the mechanism and therapeutic application of BDNF and proBDNF/mBDNF imbalance in the above-mentioned neurodegenerative diseases to provide new perspective and approach for the pathogenesis, early diagnosis and treatment of neurodegenerative diseases such as AD and PD.
RESUMEN
BACKGROUND@#China bears the biggest atrial fibrillation (AF) burden in the world. However, little is known about the incidence and predictors of AF. This study aimed to investigate the current incidence of AF and its electrocardiographic (ECG) predictors in general community individuals aged over 60 years in China.@*METHODS@#This was a prospective cohort study, recruiting subjects who were aged over 60 years and underwent annual health checkups from April to July 2015 in four community health centers in Songjiang District, Shanghai, China. The subjects were then followed up from 2015 to 2019 annually. Data on sociodemographic characteristics, medical history, and the resting 12-lead ECG were collected. Kaplan-Meier curve was used for showing the trends in AF incidence and calculating the predictors of AF. Associations of ECG abnormalities and AF incidence were examined using Cox proportional hazard models.@*RESULTS@#This study recruited 18,738 subjects, and 351 (1.87%) developed AF. The overall incidence rate of AF was 5.2/1000 person-years during an observation period of 67,704 person-years. Multivariable Cox regression analysis indicated age (hazard ratio [HR], 1.07; 95% confidence interval [CI]: 1.06-1.09; P < 0.001), male (HR, 1.30; 95% CI: 1.05-1.62; P = 0.018), a history of hypertension (HR, 1.55; 95% CI: 1.23-1.95; P < 0.001), a history of cardiac diseases (HR, 3.23; 95% CI: 2.34-4.45; P < 0.001), atrial premature complex (APC) (HR, 2.82; 95% CI: 2.17-3.68; P < 0.001), atrial flutter (HR, 18.68; 95% CI: 7.37-47.31; P < 0.001), junctional premature complex (JPC) (HR, 3.57; 95% CI: 1.59-8.02; P = 0.002), junctional rhythm (HR, 18.24; 95% CI: 5.83-57.07; P < 0.001), ventricular premature complex (VPC) (HR, 1.76; 95% CI: 1.13-2.75, P = 0.012), short PR interval (HR, 5.49; 95% CI: 1.36-22.19; P = 0.017), right atrial enlargement (HR, 6.22; 95% CI: 1.54-25.14; P = 0.010), and pacing rhythm (HR, 3.99; 95% CI: 1.57-10.14; P = 0.004) were independently associated with the incidence of AF.@*CONCLUSIONS@#The present incidence of AF was 5.2/1000 person-years in the studied population aged over 60 years in China. Among various ECG abnormalities, only APC, atrial flutter, JPC, junctional rhythm, short PR interval, VPC, right atrial enlargement, and pacing rhythm were independently associated with AF incidence.

Objective:To investigate the effects of insulin resistance induced by long-term high-fat diet on cognitive function and brain phosphorylated Tau protein in pR5 MAPT Tau transgenic mice.Methods:Eight-week-old female pR5 MAPT transgenic mice were divided into standard diet(STD) group (pR5 STD, n=8) and high-fat diet(HFD) group (pR5 HFD, n=8). Female wild-type C57BL/6 mice fed with STD were used as control group (WT STD, n=8). The experiment was carried out for 30 weeks until the mice were old.During the experiment, the weight of mice was measured once a week and fasting blood glucose was measured once every two weeks.Thirty weeks later, glucose tolerance test and insulin tolerance test were carried out.Forced swimming test and tail suspension test were used to evaluate the depressive behavior of mice, and elevated plus maze test was used to evaluate the anxiety behavior, Morris water maze test was used to evaluate spatial memory behavior.The levels of total Tau protein and phosphorylated Tau proteins H7-tau, p-tau-Ser396 and p-tau-Thr231 were detected by Western blot.SPSS 17.0 software was used for statistical analysis, repeated measurement ANOVA was used for the data of glucose tolerance test and insulin tolerance test, one-way ANOVA was used for multi group comparison, and LSD test was used for further pairwise comparison. Results:After 30 weeks of high-fat diet, there were significant differences in body weight and fasting blood glucose among the three groups ( F=808.31, 1 117.18, both P<0.01). The body weight of mice in pR5 HFD group ((54.35±2.52)g) was higher than those in pR5 STD group ((24.95±1.15) g) and WT STD group ((23.86±1.10) g) (both P<0.01), and the fasting blood glucose of mice in pR5 HFD group ((8.12±0.24) mmol/L) was significantly higher than those in pR5 STD group ((4.64±0.13) mmol/L) and WT STD group ((4.45±0.22) mmol/L) (both P<0.01). Glucose tolerance test showed that within 120 minutes after injection of glucose, there was a significant time and group interaction in the blood glucose value among the three groups ( F=113.30, P<0.01). After glucose injection, the peak value of blood glucose in pR5 HFD group was delayed, suggesting that glucose tolerance in pR5 HFD group was impaired.The insulin tolerance test showed that there was a significant interaction between time and group in the insulin tolerance among the three groups ( F=209.92, P<0.01). After injection of insulin, the blood glucose in pR5 HFD group decreased slowly, reaching the valley value at 60 min, and then the blood glucose increased significantly, suggesting that the sensitivity of pR5 HFD group mice to insulin decreased significantly.There were significant differences in the percentage of forced swimming immobility time and tail suspension immobility time among the three groups ( F=37.05, 59.29, both P<0.01). The two indexes of pR5 STD group and pR5 HFD group were both higher than those of WT STD group (all P<0.01), and those of pR5 HFD group were both higher than those of pR5 STD group (both P<0.01). The results of elevated plus maze showed that there were significant differences in the activity distance and time in open arm among the three groups ( F=7.82, 10.37, both P<0.05) .The activity distance ((0.40±0.21) m) and activity time ((27.38±8.80) s) of pR5 HFD group were significantly lower than those of pR5 STD group ((2.31±1.74) m, (63.56±27.52)s) (both P<0.05). The space exploration test showed that the residence time in the target quadrant of pR5 HFD group ((15.56±1.16)s) was less than that of pR5 STD group((19.18±0.64)s)( P<0.01), and the time of entering the platform area of pR5 HFD group((1.43±0.06)s) was less than that of pR5 STD group((1.66±0.12)s)( P<0.01). Western blot showed that there were significant differences in the levels of total Tau protein, H7-tau, p-tau-Ser396 and p-tau-Thr231 protein among the three groups ( F=101.50, 80.60, 55.47, 30.89, all P<0.05). Further pairwise comparison showed that the levels of the four Tau proteins showed: the levels of the proteins in pR5 STD group and pR5 HFD group were all higher than those of WT STD group (all P<0.01), and those in pR5 HFD group were all higher than those in pR5 STD group (all P<0.05). Conclusion:Long-term high fat diet causes obesity, hyperglycemia and peripheral insulin resistance, and promotes the cognitive impairment of MAPT mice, which is related to the increase of Tau protein phosphorylation in the brains of MAPT mice.
RESUMEN
Objective:To explore the features of free uroflow(FF) curve patterns in female patients with detrusor underactivity(DU) and their clinical significance.Methods:Data of 275 adult female patients with lower urinary tract symptoms(LUTS) underwent urodynamic studies(UDS) at urology center of our hospital from June 2014 to June 2016 were analyzed retrospectively. The uroflow curve patterns of patients with DU were classified and analyzed in the context of parameters of FF, cystometry (CM), and pressure-flow study(PFS). The prevalence of each abnormal uroflow curve pattern in DU patients were calculated and compared with those in non-DU patients.Results:No bell-shaped curve was found in 141 patients with DU. The abnormal curve patterns can be divided into 5 types: Type Ⅰ (bell-shaped curve with saw tooth) in 20 cases (14.2%), Type Ⅱ (box-like curve) in 34 cases (24.1%), Type Ⅲ (triangle curve with decreasing slop) in 62 cases(43.9%), Type Ⅳ (triangle curve with increasing slop) in 4 cases (4.3%), Type Ⅴ (tide-wave curve)in 19 cases (13.5%). Maximum flow rate of free uroflow(Q max.FF) of type Ⅰ [(28.4±9.7) ml/s] was significantly greater than that of type Ⅱ, Ⅲ and Ⅴ[(17.0±4.1), (15.8±5.4) and (12.9±6.4) ml/s, P<0.05]. Flow time of free uroflow(FT.FF) of type Ⅲ and Ⅴ [(43.7±17.2) and (50.1±28.9)s] were significantly longer than that of type Ⅰ and Ⅱ [(18.5±7.3)s and (27.2±9.7)s, P<0.05]. Post voided residual > 50ml was noted in 19 cases (30.6%) of type Ⅲ, 7 cases (36.8%) of type Ⅴ, 1 case (2.9%) of type Ⅱ and no one in type Ⅰ and Ⅳ. Abnormal manifestations in cystometry mainly included bladder hypersensitivity, detrusor overactivity, and stress urinary incontinence. Detrusor pressure at Q max (Pdet.Q max) of type Ⅴ [(7.4±5.0) cmH 2O] was significantly lower than that of type Ⅰ, Ⅱ, Ⅲ [(11.8±6.7), (12.0±5.3), (12.1±5.0) cmH 2O, P<0.05]. Among 134 cases of non-DU, there were type Ⅰ curves in 88 cases (65.7%), type Ⅱ curves in 4 cases (2.9%), type Ⅲ curves in 15 cases (11.2%), type Ⅳ curves in 1 cases (0.7%), type Ⅴ curves in 7 cases (5.2%). And normal bell-shaped curves in 19 cases(14.2%). The prevalence of type Ⅱ, Ⅲ and Ⅴ in DU patients was significantly higher than that in the non DU patients ( P<0.05). Conclusions:This study reveals that the characteristics of reduced detrusor contractility and duration, prolonged bladder emptying or incomplete emptying can be reflected in the patterns of free uroflow curve in female patients with DU. The abnormalities of these free uroflow curve patterns, especially type Ⅱ, Ⅲ and Ⅴ will be helpful in preliminarily screening DU in females.
RESUMEN
Objective To investigate NIMA-related kinase 2 (NEK2) expression in colorectal cancer (CRC) tissues and its effect on the proliferation, migration and invasion of HCT116 cells. Methods Synthesized siRNA targeting NEK2 was transfected into HCT116 cells by lipofectamine method. CCK8 assay, FACS, wound healing assay and Transwell assay were used to detect the effects of NEK2 knockdown on cell proliferation, cell cycle distribution, migration and invasion. Western blot was carried out to detect the expression of E-cadherin, N-cadherin, CDK4 and cyclin D1. Results The expression of NEK2 in CRC tissues was significantly higher than that in adjacent normal tissues (65.0% vs. 35.0%, χ2=14.593, P < 0.01), and its level was closely related to TNM stage, lymph node metastasis and distant metastasis (all P < 0.05). NEK2 protein and mRNA levels in CRC cell lines were also significantly higher than those in normal colorectal mucosal cells (P < 0.01). After NEK2 was knocked down by siRNA, HCT116 cells were arrested in G0/G1 cycle, while cell proliferation, invasion and migration were significantly reduced (P < 0.01). NEK2 interference in HCT-116 cells led to the upregulation of E-cadherin and downregulation of N-cadherin, CDK4 and cyclin D1 at protein levels. Conclusion The high NEK2 expression is correlated with clinicopathological characteristics of CRC patients. NEK2 knockdown by siRNA could effectively inhibit the proliferation, invasion and migration abilities of colorectal cancer cells, suggesting that NEK2 plays an important role in the occurrence and development of colorectal cancer and it can be used as a potential treatment target.

RESUMEN
Data of 643 patients who underwent endoscopic polypectomy with high-frequency electrotome in 6 hospitals of Sichuan Province between June 2020 and September 2020 were summarized. The rate of complete polypectomy and the incidence of delayed post-polypectomy bleeding (DPPB) and perforation were analyzed. DPPB occurred in 18 cases (2.80%) and postoperative perforation occurred in 1 case (0.16%). All of the 1 828 polyps were completely resected (100.0%). Univariate analysis showed that polyps′ diameter≥10 mm, long peduncle or laterally spreading tumor (LST), adenomatous polyp, endoscopic mucosal resection, mixed cutting mode 1 of electrocoagulation were significantly correlated with DPPB( P<0.05). Multivariate Logistic regression analysis revealed that polyp diameter≥10 mm ( P=0.001, OR=3.575, 95% CI: 1.175-9.955), morphology of long peduncle or LST ( P=0.004, OR=2.981, 95% CI: 1.233-14.858) were independent risk factors for DPPB. Endoscopic colorectal polypectomy with high-frequency electrotome is effective and safe. Polyps′ diameter≥10 mm, polyps with long pedicle or LST are the risk factors for DPPB.
RESUMEN
Purpose@#The goal of this study was to describe the current status of oncology nurses' behaviors toward end of life (EOL) care in China and to explore the factors associated with oncology nurses’ behaviors toward EOL care. @*Methods@#A cross-sectional design was applied and a convenience sample of 1038 oncology nurses from 22 grade A hospitals were recruited into this study. A general social demographic data questionnaire was administered, and the Chinese version of Nurses’ Behaviors of Caring for Dying Patients Scale was used to assess nurse behavior toward EOL care. The total score ranges from 40 to 200 points. Data were analyzed with SPSS 26.0 software. @*Results@#Chinese oncology nurses' average score of holistic EOL care behaviors was 2.97 ± 0.59. Oncology nurses provide physical care most (3.81 ± 0.76), followed by family care (3.02 ± 0.86), and spiritual care (2.37 ± 0.67). Multiple regression analysis showed that a higher frequency of sharing EOL care experience with colleagues, in-service palliative care education, higher level of head nurse support for EOL patient care, more cases of EOL care, higher working position, and nurse's perceived high level of support were positively associated with behavior toward EOL care. These six factors explained 16.2% of the total variance. @*Conclusions@#The results may help provide a basis for converting behavior for EOL care among oncology nurses and design interventions to better improve quality of life for EOL patients with cancer in China.
RESUMEN
Objective:To investigate the correlation between blood pressure changes within 24 h after intravenous thrombolysis and the outcome in patients with acute ischemic stroke.Methods:Patients with acute ischemic stroke treated with alteplase intravenous thrombolysis in the Department of Neurology, Anhui No. 2 Provincial People's Hospital from June 2018 to September 2020 were enrolled retrospectively. The patients who received antihypertensive therapy before and within 24 h after intravenous thrombolysis were excluded. The blood pressure before intravenous thrombolysis and the blood pressure drop within 24 h after intravenous thrombolysis were recorded. The modified Rankin Scale was used to evaluate the clinical outcome at 90 d after the onset. 0-2 was defined as good outcome, and >2 was defined as poor outcome. Multivariate logistic regression analysis was used to investigate the independent correlation between blood pressure changes within 24 h after intravenous thrombolysis and the clinical outcomes. Results:A total of 205 patients with acute ischemic stroke were enrolled, including 125 males (60.98%), 80 females (39.02%); aged 63.30±9.63 years; 124 (60.49%) had a good outcome, and 81 (39.51%) had a poor outcome. Univariate analysis showed that the proportion of diabetic patients as well as baseline systolic blood pressure, prethrombolytic blood glucose, baseline National Institutes of Health Stroke Scale score, and the incidence of symptomatic intracranial hemorrhage in the good outcome group were significantly lower than those in the poor outcome group, and the proportion of patients with small vessel occlusion and the decrease in systolic blood pressure within 24 h after thrombolytic therapy were significantly higher than those in the poor outcome group (all P<0.05). Multivariate logistic regression analysis showed that higher baseline systolic blood pressure was independently associated with the poor outcome at 90 d after intravenous thrombolysis (odds ratio 0.964, 95% confidence interval 0.942-0.987; P=0.002), and a greater decrease in systolic blood pressure within 24 h after intravenous thrombolysis was independently associated with a good outcome (odds ratio 1.134, 95% confidence interval 1.067-1.206; P<0.001). Conclusion:For patients with acute ischemic stroke who received intravenous thrombolysis, higher baseline blood pressure before intravenous thrombolysis was associated with the poor outcome, and greater decrease in systolic blood pressure within 24 h after intravenous thrombolysis was associated with the good outcome.

Objective To investigate the clinical effect of milrinone injection combined therapy in patients with cor pulmonale complicated with respiratory failure and observe the effect of milrinone on blood gas index, blood viscosity and pulmonary arterial pressure.Methods The clinical data of 100 patients with cor pulmonale complicated with respiratory failure were retrospectively analyzed from April 2014 to April 2016.Among them, 50 cases were treated with conventional oxygen therapy, diuretic, asthma and anti-infection treatment.In the control group, 50 cases were treated with milrinone injection as the treatment group.The clinical curative effect and adverse reaction were analyzed.The blood gas analysis index, blood viscosity and pulmonary arterial pressure were measured before and after the treatment.The sputum normal and cyanosis, cough, wet rales and edema time were recorded in the two groups.Results The total effective rate of the treatment group was 92.0%, which was significantly higher than that of the control group 70.0%(P <0.05).After treatment, the hemorheological indexes and blood gas analysis indexes of the two groups improved significantly, However, the improvement of the indicators of the treatment group were significantly better than the control group (P<0.05).The pulmonary arterial pressure in the treatment group was (18.36 ±7.38) mmHg, which was significantly lower than that in the control group (23.79 ±6.14) mmHg (P<0.05); After treatment, the sputum normal and cyanosis in the treatment group, cough, wet rales, edema time were significantly shorter than the control group ( P <0.05 ) .No significant adverse effects were observed in both groups during the treatment.Conclusion The use of milrinone injection comprehensive treatment of pulmonary heart disease with respiratory failure in patients with significant efficacy and safety , but also can help improve blood viscosity and blood gas analysis indicators, reduce pulmonary artery pressure, better promote the rehabilitation of patients.
RESUMEN
Objective@#To investigate the dynamic change of paraquant-induced kidney injury in rats and the protective effect of edaravone.@*Methods@#Eighty SD rats were randomly divided into 4 groups: the normal control group, paraquat poisoning group, edaravone treatment group and edaravone control group. The normal control group of 8 rats were given 1 ml of 0.9% sodium chloride through the abdominal cavity, and the same amount of fluid into the abdominal cavity after 30 minutes. The paraquat poisoning group of 24 rats were given 1 ml of paraquat solution (20 mg/kg) through the abdominal cavity to build poisoning models, and the same amount of 0.9% sodium chloride was injected into the abdominal cavity after 30 minutes. The edaravone treatment group of 24 rats were given edaravone (5 mg/kg) through the abdominal cavity after 30 minutes when the poisoning models were set up. The edaravone control group of 24 rats were given 1 ml of 0.9% sodium chloride through the abdominal cavity, and edaravone (5 mg/kg) was injected into the abdominal cavity after 30 minutes. In addition to the normal control group, the other groups processed 1 times a day to mantain 7 d. On 1, 3, 7, 21 d several rats in each group were excuted and the kidney tissue and serum samples were collected, then each pathological changes of the kidney were observed with light microscopy. Serum creatinine, KIM-1, NGAL were measured by ELISA, the expression of HSP70 protein in kidney were observed with immunohistochemical staining.@*Results@#The pathological examination reveald that the damage of kidney tissue in the paraquat group was the most serious on 3 d, and the damage was consistently alleviated in edaravone treatment group at the same time, renal fibrosisn was unseen in each group until 21 d. Compared with normal control group, there was no statistically significant in edaravone control group (P>0.05) . The KIM-1 in blood and kidney in paraquat poisoning group were markedly increased in 1 d (P<0.05) . The NGAL in blood and creatinine were markedly increased in d7 (P<0.05) . The NGAL in kidney increased over time, but had no statistically difference with the control group (P>0.05) .Compared with paraquat poisoning group, the serum creatinine, KIM-1 in blood and kidney, the KIM-1 in kidney had decreased significantly in edaravone treatment group (P<0.05) . The NGAL in kidney has no statistically significant compared with the poisoning group (P>0.05) . HSP70 expression of kidney tissue in edaravone treatment group had significantly increased in d3 compared with the paraquat poisoning group (P<0.05) .@*Conclusion@#Edaravone can prompt a significant rise of HSP70 in kidney tissue, reduce KIM-1 and NGAL levels, and play a protective role in kidney injury of acute paraquat poisoning.
