ABSTRACT

Objective:To analyze the relationship between reticular macular disease (RMD) and chronic kidney disease (CKD) by estimated glomerular filtration rate (eGFR).Methods:A cross-sectional study was conducted.Thirty-six consecutive patients (71 eyes) with subretinal drusenoid deposits in at least one eye in optical coherence tomography (OCT) images were enrolled as the RMD group, and 29 consecutive patients (50 eyes) with age-related macular degeneration (AMD) in at least one eye were identified as the non-RMD group at the First Affiliated Hospital of Guangzhou Medical University from February to September 2019.In the same period, 32 healthy volunteers (64 eyes) without eye disease were included as the healthy control group.Serum was collected to calculate the estimated creatinine clearance (eCcr) and the eGFR.The choroidal thickness of macular fovea and the flow density of choroidal capillary layer were measured by OCT.The related factors of RMD and the correlation between CKD and RMD were analyzed by multiple logistic regression analysis.The relationship between eGFR and choroidal capillary blood flow density and foveal choroidal thickness in RMD patients was analyzed by Pearson linear correlation analysis.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of the First Affiliated Hospital of Guangzhou Medical University (No.2022-50)Results:The eGFR value of the RMD group was (66.40±27.58)ml/(min·1.73 m 2), which was significantly lower than (84.40±20.91)ml/(min·1.73 m 2) of the non-RMD group and (87.64±22.32)ml/(min·1.73 m 2) of the healthy control group (both at P<0.01). eGFR was significantly correlated with the occurrence of RMD ([odds ratio, OR]=0.973, 95%[confidence interval, CI]: 0.954-0.992, P=0.005). Subgroup analysis showed that this correlation was significant in the CKD stage (eGFR<60 ml/[min·1.73 m 2]) ( OR=6.482, 95% CI: 1.543-27.236, P=0.011). The choroidal thickness of the macular fovea in the RMD group was significantly lower than that of the non-RMD grup and healthy control group (both at P<0.01). In the RMD group, no significant correlation was found between the choroidal thickness of the macular fovea and eGFR ( r=0.138, P>0.05), and the flow density of choroidal capillary layer was moderately positively correlated with eGFR ( r=0.457, P<0.05). Conclusions:There is a correlation between the occurrence of CKD and RMD, which may be due to the confounding effect of the systemic microcirculation disorder.

ABSTRACT

Objective:To investigate the value of high-flow oxygen therapy after weaning in successful extubation of critically ill patients with mechanical ventilation.Methods:A retrospective study was conducted. The weaned patients who were older than 18 years old and underwent mechanical ventilation for the first time due to cerebrovascular accidents, surgical operations, cardiovascular diseases, and pneumonia admitted to the department of critical care medicine of Zhejiang Hospital from January 2018 to June 2020 were enrolled. Among the patients, 40 cases received high-flow oxygen therapy after weaning, and 37 cases received Venturi combined with the humidifier. The patient's gender, age, primary disease, severity score, duration of mechanical ventilation before weaning, heart rate (HR), blood pressure, pulse oxygen saturation (SpO 2) at 0, 6, 12, 18, and 24 hours after weaning, and pH value, arterial partial pressure of oxygen (PaO 2), arterial partial pressure of carbon dioxide (PaCO 2) at 6, 12, 18, and 24 hours after weaning, the rate of performing mechanical ventilation after weaning, extubation time after weaning, and the rate of reintubation after extubation for 72 hours were collected. Results:There was no significant difference in baseline data such as gender, age, primary disease, severity score, and duration of mechanical ventilation before weaning between the two groups. After weaning, the vital signs of the two groups were stable, and there was no significant difference in HR, systolic blood pressure (SBP), diastolic blood pressure (DBP) or SpO 2 at each time point between the two groups. After weaning, the pH of arterial blood gas analysis in the two groups and the fluctuations of PaO 2 and PaCO 2 in the high-flow group were not obvious. In the Venturi group, PaO 2 gradually decreased after weaning, PaCO 2 increased significantly at 12 hours, and slowly decreased after 12 hours. The PaO 2 from 6 hours and PaCO 2 from 12 hours in the high-flow group were significantly lower than those in the Venturi group, and continued to 24 hours [PaO 2 (mmHg, 1 mmHg≈0.133 kPa): 112.34±38.25 vs. 156.76±68.44 at 6 hours, 110.92±38.66 vs. 150.64±59.07 at 12 hours, 111.12±36.77 vs. 141.30±39.05 at 18 hours, 110.82±39.37 vs. 139.65±41.50 at 24 hours; PaCO 2 (mmHg): 41.30±7.51 vs. 47.42±7.54 at 12 hours, 40.97±6.98 vs. 45.83±8.63 at 18 hours, 40.10±7.06 vs. 46.14±9.15 at 24 hours, all P < 0.01]. The rate of performed mechanical ventilation after weaning and the rate of reintubation after extubation for 72 hours in the high-flow group were significantly lower than those in the Venturi group [17.5% (7/40) vs. 40.5% (15/37), 6.2% (2/32) vs. 31.8% (7/22), both P < 0.05], and the extubation time after weaning was significantly shorter than that in the Venturi group (hours: 22.43±11.72 vs. 28.07±10.42, P < 0.05). Conclusion:Using high-flow oxygen therapy to the extubation process of critically ill mechanical ventilation patients can reduce the incidence of carbon dioxide retention and the rate of performed mechanical ventilation after weaning, shorten the extubation time after weaning, and reduce the rate of reintubation after extubation for 72 hours.

ABSTRACT

Huatan Jiangzhuo decoction (HJD) is a combination of six traditional Chinese medicines that were used for lipid metabolism-related disorders, but its efficacy and underlying mechanisms have not been explored by modern research strategies. This study aimed to investigate the therapeutic role of HJD in determining the transcriptome level. Hyperlipidemia model was established by feeding Sprague-Dawley rats with high-fat diet. Differentially expressed genes (DEGs) were detected by high-through transcriptome sequencing, followed by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. The total cholesterol (TC) and triglyceride (TG) levels in hyperlipidemia model rats were significantly increased, whereas high-density lipoprotein (HDL) concentration decreased when compared to normal rats, and HJD significantly downregulated TC concentrations and liver coefficient in the hyperlipidemia rats. Histology staining showed that HDJ greatly recovered the lipid accumulation in rat hepatic stellate cells and aortic arch vascular wall thickness of hyperlipidemia rats. One thousand nine hundred and thirty-six DEGs were identified in the HJD-treated hyperlipidemia rats, which were associated with various biological processes and signaling pathways such as peroxisome proliferator-activated receptors, AMP-activated Protein Kinase , and insulin signaling pathways. Quantitative reverse transcription-polymerase chain reaction further confirmed the downregulated expression of cholesterol 7-α-hydroxylase(CYP7A1), liver orphan receptor(LXRα),peroxisome proliferator-activated receptor gamma(PPARγ),andSterol Response Element-Binding Protein 1c(SREBP1c) genes in hyperlipidemia rats treated with HJD. Our data first elucidated the gene expression profile of high-fat diet-induced hyperlipidemia in rats after HJD treatment, and lipid metabolism-related genes (CYP7A1, LXRα, PPARγ, and SREBP1c) may be potentially biomarkers for HJD-alleviated hyperlipidemia.

ABSTRACT

Objective:To investigate the nurses' attitude towards open visitation policy in intensive care unit (ICU) and its potential influence factors, and further to provide evidence for carrying out this policy in ICU.Methods:A self-designed, anonymous online questionnaire of "attitude of ICU nurses to open visiting system in ICU" was performed in 31 provinces, autonomous regions and municipalities in China from October to December 2019, using convenient sampling method approach. Only nurses working in ICU (including specialized ICU, but excluding the critical ward in general ward) and willing to participate in the survey were included. The survey included 35 items, including the general information of each participant, the attitude towards the implementation of the open visitation system in ICU and its potential influencing factors. Ordinal Logistic regression analysis was used to identify the significant influencing factors.Results:A total of 1 558 questionnaires were sent out and 1 546 effective questionnaires were retrieved, with a response rate of 99.2%. Overall, 32.2% of them agreed with the policy, 41.3% of them disagree with the policy and 26.5% of them were uncertain. The Ordinal Logistic regression analysis showed that the independent influencing factors of ICU nurses' attitude towards open visitation policy including the possibility of increasing healthcare-associated infection [disagree: β = 1.327, 95% confidence interval (95% CI) was 0.242 to 2.413, P = 0.017; uncertain: β = 0.697, 95% CI was 0.244 to 1.151, P = 0.003], the improvement of nurses' job satisfaction (disagree: β = -1.406, 95% CI was -1.750 to -1.062, P = 0.000; uncertain: β = -0.748, 95% CI was -1.030 to -0.466, P = 0.000), the information support for medical staffs from family members (disagree: β = -0.644, 95% CI was -1.048 to -0.240, P = 0.002; uncertain: β = -0.422, 95% CI was -0.721 to -0.124, P = 0.006), the feasibility that the family members can assist the nurses in the basic nursing for patients (uncertain: β = -0.465, 95% CI was -0.729 to -0.202, P = 0.001), reducing the time that a nurse spent on caring for the patients (uncertain: β = 0.349, 95% CI was 0.052 to 0.646, P = 0.021), improving early rehabilitation (disagree: β = -0.593, 95% CI was -1.166 to -0.019, P = 0.043), and getting psychological support for patients from family members (disagree: β = 1.293, 95% CI was 0.426 to 2.159, P = 0.003), family members' satisfaction (disagree: β = -0.981, 95% CI was -1.431 to -0.531, P = 0.000). Conclusion:ICU nurses in China have realized that open visitation policy has positive effect on patients' early rehabilitation, willing to live and satisfaction; meanwhile, this policy may need more improvement in many ways such as healthcare-associated infection control, disinfection and isolation, allocation of human resources and time spent treating and caring for patients.

ABSTRACT

OBJCTIVE@#To study the clinical effect of surgery combined with chemotherapy and radiotherapy in children with central primitive neuroectodermal tumor (cPNET), as well as the risks factors for poor prognosis.@*METHODS@#A retrospective analysis was performed for the clinical data of 42 children who were diagnosed with cPNET from June 2012 to September 2018.@*RESULTS@#The 42 children had a median overall survival (OS) time of 2.0 years and a median event-free survival (EFS) time of 1.3 years; the 1-, 3-, and 5-year OS rates were 76.2%±6.6%, 41.4%±8.7%, 37.3%±8.8% respectively, and the 1-, 3-, and 5-year EFS rates were 64.3%±7.4%, 32.7%±8.0%, 28.0%±8.1% respectively. The univariate analysis showed that there were significant differences in the OS and EFS rates among the children with different patterns of surgical resection, chemotherapy cycles, and risk grades (P<0.05), and there was also a significant difference in the OS rate between the children receiving radiotherapy and those not receiving radiotherapy (P<0.05). The multivariate Cox regression analysis showed that chemotherapy cycles and risk grade were independent influencing factors for EFS and OS rates (P<0.05). The EFS and OS rates increased with the increase in chemotherapy cycles and the reduction in risk grade.@*CONCLUSIONS@#Multimodality therapy with surgery, chemotherapy, and radiotherapy is an effective method for the treatment of cPNET in children. Early diagnosis and treatment and adherence to chemotherapy for as long as possible may improve EFS and OS rates.

ABSTRACT

Objective@#To analyze Internet behaviors of children and adolescents and their influencing factors, and to provide scientific basis for health education guidance and prevention measures.@*Methods@#A stratified cluster sampling method was used. From January to June 2019, 30 955 primary school students in 16 provinces (municipalities), from eastern, central, and western economic zones of China were selected to conduct a questionnaire survey, regarding general demographics, diet and exercise, tobacco, alcohol and sleep, Internet and electronics usage, etc.@*Results@#Among them, 43.1% of students had never been online with girls (44.7%) higher than boys (41.8%)(χ2=21.04, P<0.01); 1.3% of students reported online time for more than 4 hours a day, boys were significantly higher than girls(χ2=15.87, P<0.01); Internet addiction was detected in 2.4% of elementary school students, with boys (3.0%) higher than girls(1.7%)(χ2=331.77, P<0.01), and the trend increases with grade. With sixth grade (3.3%) were significantly higher than children from the first grade (0.8%) and other grades(χ2=163.96, P<0.01). Children’s tendency to Internet addiction was 11.9%, of which boys were 13.0% and girls were 10.6%, boys were significantly higher than girls(χ2=117.66, P<0.01). Pearson correlation analysis revealed that, after controlling gender age, boarding school, family relationship, single parents and regrouped families, smoking, drinking sugary drinks, eating fried foods, and left-behind were positively related to Intenet addiction(r=0.06, 0.07, 0.27, 0.44, 0.07, 0.11, 0.09, P<0.01), while medium and high intensity sports, effective physical education, health education in school, AIDS education and parental restrictions on TV and computer games, were negatively associated with internet addiction(r=-0.74, -0.65, -0.04, -0.05, -0.63, P<0.01).@*Conclusion@#The internet addiction of Chinese primary school students is common and increases by year. High-intensity, high-density sports, effective physical education, and health education could help prevent Internet addiction among children.

ABSTRACT

ObjectiveCardiovascular calcification is a highly common complication in patients with end stage renal disease. The aim of this study was to explore the effect of cardiac valve calcification (VC) on left ventricular function and morphology in patients with end stage renal disease by echocardiography. Methods Echocardiography results of 137 patients with end stage renal disease who underwent hemodialysis in the general hospital of the eastern theater of war from June 2013 to August 2013 were retrospectively analyzed. The morphological structure and function parameters of the left ventricle were measured by echocardiography and tissue doppler imaging to assess cardiovascular calcification. Logistic regression analysis was used to investigate the independent risk factors of cardiac valve calcification.Results VC was found in 55 patients (40.1%) in this study. The age [(52.7±11.1) vs (42.6±12.3)], low density lipoprotein [(2.7±0.8)mg/dL vs (2.2±0.6)mg/dL], cholesterol [(5.2±1.1)mg/dL vs (4.5±0.9)mg/dL] levels were higher, while serum creatinine [(10.7±2.7)mg/dL vs (13.2±8.5)mg/dL] was lower in patients with VC than patients without VC (P<0.05). Logistic regression analysis showed that the older age, longer dialysis time and higher mean value of mitral annular systolic values were the independent risk factors for VC. The morphological and structural parameters of the left ventricle of the group with VC were higher than those of the group without VC (P<0.05), while the parameters of left ventricular diastolic function of the group with VC were lower than those of the group without VC (P<0.05).ConclusionVC diagnosed by echocardiography in patients with end stage renal disease may indicate significantly higher incidence of left ventricular hypertrophy and reduction of left ventricular diastolic function in comparison to those without VC.

ABSTRACT

OBJECTIVE@#To investigate the effect of bevacizumab in the treatment of children with optic pathway glioma (OPG).@*METHODS@#A retrospective analysis was performed for the clinical data of 30 children with OPG who underwent chemotherapy. According to whether bevacizumab was used, they were divided into conventional chemotherapy (carboplatin, vincristine and etoposide) group with 12 children and combined chemotherapy (bevacizumab, carboplatin, vincristine and etoposide) group with 18 children. The children were followed up to 6 months after chemotherapy, and the two groups were compared in terms of visual acuity and tumor size before and after chemotherapy and adverse reactions during chemotherapy.@*RESULTS@#The combined chemotherapy group had a significantly higher proportion of children achieving tumor regression than the conventional chemotherapy group (P0.05). No chemotherapy-related death was observed in either group.@*CONCLUSIONS@#Bevacizumab combined with conventional chemotherapy can effectively reduce tumor size. Compared with conventional chemotherapy, such combination does not increase adverse reactions and can thus become a new direction for the treatment of OPG in children.

ABSTRACT

@# Objective To investigate the relationship between interleukin 10 (IL-10) -592 (rs1800872) and -819 (rs1800871) promoter genetic polymorphisms and the susceptibility of antituberculosis drug-induced liver injury (ADLI). Methods A case-control study was conducted. Epidemiology survey data and peripheral blood samples were obtained from the patients. Two IL-10 gene polymorphisms (-592 A/C and 819 C/T) were genotyped with PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) in Chinese Han ADLI subjects (n=180) and sex matched by frequency matching in control subjects (n=180). Results No significant differences in genotypes of IL-10 -592 site and IL-10 -819 site between ADLI group and that of the control group were noticed (all P>0.05). The mutant alleles -592 C of IL-10 gene polymorphism was significantly higher in ADLI subjects compared to controls, and in dominant model, the frequency of CC+AC genotype was 1.62 higher among the cases than controls (all P<0.05). Significant difference in allele -819 C/T between the ADLI group and the control group were not found (P=0.190). The polymorphisms at -819 C/T and -592 A/C variants of IL-10 gene were found to be good linkage disequilibrium. The CC haplotype represent genetic risk factor (OR=1.37, 95% CI: 1.02-1.85) and CA haplotype represent genetic protect factor (OR=0.49, 95% CI: 0.34-0.70) for ADLI in the subjects. Conclusions The polymorphisms in IL-10 gene -592 A/C and -819 C/T are associated with ADLI.

ABSTRACT

Objective To study the effect of different doses of radiation on intestinal injury,with an attempt to find the optimal radiation dose for establishing intestinal injury models in NOD/SCID mice. Methods Forty healthy male SPF-grade NOD/SCID mice were divided randomly into four groups:blank control group and 4-,5-,6-Gy irradiatio groups,with 10 mice in each group. The irradiation rate was 1 Gy/min. The general conditions,body weight,intestinal bacterial translocation,and histopathologic changes were observed and compared. Results The survival rate was 60%,50%,and 30% in the 4-,5-,and 6-Gy groups 15 days after irradiation,and the intestinal bacterial translocation rate was 20%,50%,and 70%,respectively. The body weights in 5-Gy group (P=0.015) and 6-Gy group (P=0.011) were significantly higher than that in blank control group. The length of small intestinal villi decreased in the 4-Gy group. In the 5-Gy group,the structure of intestinal mucosa villi became wide,flat,and inverted,along with the shedding of epithelial cells,the atrophy of glands,and the damage of recess structures. In the 6-Gy group,the structure of intestinal mucosal villi was damaged,the villi were ruptured and smashed,and the recess structures were missing;meanwhile,there was a large amount of inflammatory cell infiltration between tissues,along with visible spotty bleeding and necrosis. The length of small intestine villi in the blank control group and 4-,5-,and 6-Gy groups were (361.77±22.77),(291.68±32.45),(248.03±51.09),and (195.90±26.39) μm,respectively. In particular,it was significantly shorter in 4-Gy group (P=0.005),5-Gy group (P<0.001),and 6-Gy (P<0.001) than in the blank control group,was significantly shorter in the 5-Gy group (P=0.041) and 6-Gy group (P=0.001) than in the 4-Gy group,and significantly shorter in 6-Gy group than in the 5-Gy group (P=0.020). Conclusion 5-Gy irradiation in mice models can decrease body weight,cause the damage of intestinal mucosa and the shedding of inflammatory cells,with stable survival rate and bacterial translocation rate.

ABSTRACT

Objective To observe the protective effect of hydroxysafflor yellow A(HSYA) on anoxia/reoxygenation (A/R) injury of neonatal primary cardiomyocytes, and its relationship with phosphoinositide 3-kinase/protein ki-nase B/glycogen synthase kinase 3β(PI3K/Akt/GSK3β) signaling pathway. Methods Primary cardiomyocytes of neonatal rats were isolated from the rats and incubated for 48 hours. The cells were adhered to each other and then divided into five groups:control group (Con group), anoxia/reoxygenation group (A/R group),HSYA treatment group(A/R+H group),PI3K inhibitor (LY294002)treatment group(A/R+L group)and HSYA+LY294002 treat-ment group (A/R+H+L group),then to collect the supernatant fluid of each group to measure LDH.The flow cy-tometry was used to measure the apoptotic cells. The protein levels of Bcl-2,Bax,Akt,p-Akt (Ser473),GSK3β, p-GSK3β (Ser9) were evalated by Western blot. Results A/R increased LDH release,the apoptosis rate (P<0.001),and the expression of pro-apoptotic protein Bax (P <0.001) with the decrease of anti-apoptotic protein Bcl-2,p-Akt(Ser473), p-GSK3β(Ser9)(P<0.001) as compared with the control group. HSYA treatment de-creased LDH release,the apoptosis rate (P<0.001),and the expression of Bax (P<0.001) and increase the ex-pression of Bcl-2,p-Akt(Ser473),p-GSK3β(Ser9)(P<0.001). Compared with the A/R+H group,the expres-sion of Bax was increased (P<0.001),while the expression of Bcl-2, p-Akt(Ser473), p-GSK3β(Ser9)was de-creased (P<0.001) in the A/R+H+L group. Conclusions HSYA protects rats'cardiomyocytes from anoxia/reoxy-genation injury by regulating PI3K/Akt/GSK3β signaling pathway.

ABSTRACT

Objective To explore the link between the expression of long non-coding RNA(lncRNA)metastasis associated lung adenocarcinoma transcript 1(MALAT1)and IL-6/signal trans ducers and activators of transcription 3(STAT3)signaling pathway in isoniazid induced rats liver injury. Methods Fifty-six specific pathogen-free(SPF)SD rats were randomly divided into experimen?tal group(48 rats)and control group(8 rats),each with half females and half males. The rats in experimental group were given isonia?zid of 63 mg/(kg·d)for 3,7,10,14,21 and 28 d,with 8 rats at the same time point of each day. The rats in control group were giv?en distilled water by intragastric administration. Serum levels of ALT and AST were measured by automatic biochemical analyzer;SYBR green real-time polymerase chain reaction was used to test the expression level of lncRNA MALAT1 and IL-6/STAT3 mRNA in the liver. Results Liver tissue injury occurred after 7 days and worsened with the extention of administration time. Compared with the rats in the control group,the expression level of lncRNA MALAT1 and IL-6/STAT3 mRNA as well as ALT and AST showed a trend of increase(P<0.01). The expression of ALT,AST and lncRNA MALAT1 declined at different degrees on 28(P<0.05). LncRNA MALAT1 and IL-6/STAT3 mRNA expression levels were positively correlated(P<0.01). LncRNA MALAT1 and IL-6/STAT3 mRNA expression levels had a positive correlation with the contents of ALT and AST(P<0.01). Conclusion The expression level of lncRNA MALAT1 in isoniazid induced liver injury rat models showed an abnormal rising trend,and the positive detection time preceded that of ALT and AST. The mechanism may be related to the activation of IL-6/STAT3 signaling pathway.

ABSTRACT

BACKGROUND: Carotid intima media thickness (CIMT) and stiffness are taken as useful surrogate markers of atherosclerosis. In China, the number of elderly patients undergoing hemodialysis has increased year by year, with the increase of dialysis-related cardiovascular events. This study was undertaken to examine carotid stiffness in elderly hemodialysis patients by the ultrasound techniques in order to find out the possible risk factors. METHODS: From January 2006 to February 2010, a total of 87 patients (41 males and 46 females) treated with routine hemodialysis at the 97th Hospital of People's Liberation Army were enrolled in this study. The distensibility coefficient (DC) of the carotid artery was detected by Doppler ultrasonic diagnosis apparatus (Philips HBI5000, frequency 12 MHz) for evaluation of arterial stiffness. Serum albumin, total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL), triglyceride (TG), glucose, creatinine, calcium, phosphorus, and intact parathyroid hormone (iPTH) were examined with standard methods. The liner correlation and multiple stepwise regression analysis were used to find correlations between them. RESULTS: In this study, the systolic blood pressure was 153.33±25.98 mmHg, DBP 84.22± 10.39 mmHg, TC 4.39±1.05 mmol/L, TG 1.36±0.72 mmol/L, LDL 2.47±0.77 mmol/L, Cr 889.82± 207.38 mol/L, Glu 5.36±1.87 mmol/L, Ca I 2.00±2.19±0.21 mmol/L, and DC 13.39±5.32×10-3/kPa. DC was associated with age (r =-0.459, P<0.001), SBP (r =-0.527, P<0.001), and serum calcium (r =-0.273, P=0.011). The multiple stepwise regression analysis showed that SBP, age, increased serum calcium level, and diabetes were independent risk factors for decreasing DC. CONCLUSION: Systolic blood pressure, age, increased serum calcium level and diabetes in elderly hemodialysis patients are independent risk factors for increased carotid arterial stiffness.
