ABSTRACT

Objective:To evaluate the effect of eye-covering pretreatment on acute delirium in ophthalmology preschool-age children who underwent binocular and monocular surgery by general anesthesia.Methods:The 300 preschool-age children who underwent general anesthesia of elective ophthalmic surgery in the Second Affiliated Hospital, Zhejiang University School of Medicine, from August 2019 to February 2021 were selected as the research object. They were divided into control group and blindfold group with 150 cases each by random number-table. Children in the control group received regular education on cartoon animation videos before surgery; children in the blindfold group received eye-covering pretreatment on the basis of cartoon animation videos(monocular surgery with monocular cover, binocular surgery with binocular cover). The Modified Yale Preoperative Anxiety Scale (m-YPAS) , the Nursing Delirium Screening Scale(NU-DESC), the incidence rate of delirium and the score of postoperative nursing difficulty were compared between two groups.Results:The 271 cases were completed in this study, including 129 cases(monocular surgery 66 cases, binocular surgery 63 cases) in the blindfold group and 142 cases (monocular surgery 73 cases, binocular surgery 69 cases) in the control group. The preoperative m-YPAS score, the postoperative NU-DESC score, the incidence rate of acute delirium and postoperative nursing care difficulty score of monocular surgery in the blindfold group , monocular surgery was (40.28 ± 15.02) points, 1.00 (0.00, 2.00) points, 27.3%(18/66), 1.00 (1.00, 2.00) points,and binocular surgery was (41.69 ± 16.35) points, 1.00 (0.00, 2.00), 39.7%(25/63), 1.00(1.00, 2.00); in the control group, monocular surgery was (46.28 ± 15.76) points, 2.00 (1.00, 3.00) points, 67.1% (49/73), 2.00 (1.00, 3.00) points, and binocular surgery was (47.77 ± 14.82) points, 3.00 (2.00, 4.00) points, 82.6% (57/69) and 2.00 (1.50, 3.00) points respectively. The difference between the two groups was statistically significant ( t= -2.29, -2.24, Z values were -5.74 - -2.95, χ2= 32.94, 25.78, all P<0.05). The preoperative m-YPAS score, the postoperative NU-DESC score, the incidence rate of acute delirium and postoperative nursing care difficulty score of monocular surgery patients in the blindfold group had no significantly statistical difference with that of binocular surgery patient (all P>0.05) . Conclusions:Monocular/ binocular eye-covering pretreatment can effectively decrease the preoperative m-YPAS score, the postoperative NU-DESC score, incidence rate of acute delirium and the postoperative nursing care difficulty in preschool-age children who underwent general anesthesia both monocular or binocular surgery. There was no difference in the application effect of monocular or binocular surgery.

ABSTRACT

SARS-CoV-2 is an emerging viral pathogen and a major global public health challenge since December of 2019, with limited effective treatments throughout the pandemic. As part of the innate immune response to viral infection, type I interferons (IFN-I) trigger a signaling cascade that culminates in the activation of hundreds of genes, known as interferon stimulated genes (ISGs), that collectively foster an antiviral state. We report here the identification of a group of type I interferon suppressed genes, including fatty acid synthase (FASN), which are involved in lipid metabolism. Overexpression of FASN or the addition of its downstream product, palmitate, increased viral infection while knockout or knockdown of FASN reduced infection. More importantly, pharmacological inhibitors of FASN effectively blocked infections with a broad range of viruses, including SARS-CoV-2 and its variants of concern. Thus, our studies not only suggest that downregulation of metabolic genes may present an antiviral strategy by type I interferon, but they also introduce the potential for FASN inhibitors to have a therapeutic application in combating emerging infectious diseases such as COVID-19.

ABSTRACT

Objective:To analysis the impact of public health emergencies on mood fluctuations of depression and the related factors in the elderly in Shanghai, in order to provide a new evidence for early psychological intervention.Methods:A cross-sectional survey was conducted among 983 elderly in the Department of Geriatrics of Xinhua Hospital Affiliated to Shanghai Jiaotong University and two communities in Changning and Hongkou Districts of Shanghai by using a self-compiled social life questionnaire and Geriatric Depression Scale(GDS-30)during corona virus disease(COVID)-19 outbreak from 1 February to 15 February 2020.The mood fluctuations of depression and the related influencing factors were analyzed by comparing the current GDS-30 scores with the scores within previous six months.Results:Of 983 questionnaires, 867 were valid.The incidence of mild fluctuations of depression was increased from 20.9%(181/867)to 27.2%(235/867)during the public health emergencies( P<0.05), with 3 cases of newly emerged severe depression.The GDS-30 scores were higher during the public health emergencies than before the emergencies(9.88±3.85 vs.7.67±3.54, P<0.05). The four risk factors inducing fluctuations of depression in the elderly were the number of coexisted chronic diseases ≥2( P=0.036), the lack of visits or communication from families( P=0.015), the family members exposing a risk to COVID-19( P<0.01), and the daily viewing of epidemic news more than 4 h( P=0.023). Linear regression analysis showed that cough, sore throat, dizziness, sleep disturbance and dyspnea were significantly related to the aggravation of depression(based on the increase of GDS-30 score)( P<0.05). Conclusions:Public health emergencies may exacerbate depression in the elderly.They are more likely to experience the aggravation of depression when they suffer from multiple chronic diseases, lack the child visits or communications, have the family members exposing a risk to COVID-19 and pay excessive attention to the epidemic.

ABSTRACT

Objective:To study the effects of cryptotanshinone on proliferation and apoptosis of human bladder carcinoma J82 cells in vitro and its mechanisms.Methods:The J82 cells were treated with cryptotanshinone of different concentrations including 0, 0.5, 1.0, 2.0, 3.0, 4.0, 5.0 and 8.0 μmol/L.After 48-hour treatment, the proliferation of J82 cells was determined by CCK-8 assay method.Flow cytometric analysis with Annexin V-FITC/PI staining was used to evaluate the apoptosis of J82 cells, and Western blotting was adopted to observe the protein expressions of p65, caspase-3, caspase-8 and caspase-9 related to proliferation and apoptosis.Results:CCK-8 results showed that the A values of 450nm-wavelength were as following: the control group (1.77±0.06), 0.5μmol/L group (1.78±0.08), 1.0μmol/L group (1.64±0.05), 2.0μmol/L group (1.48±0.12), 3.0μmol/L group (1.20±0.07), 4.0μmol/L group (0.93±0.10), 5.0μmol/L group (0.76±0.02), 8.0μmol/L group (0.05±0.01), and the A values were significantly different among the three groups ( F=329.83, P=0.00), there were statistically significant differences between any two groups except the 0.5 μmol/L group(all P<0.05). The early and total apoptosis rates were both significantly different among the three groups ( F=32.49, P=0.00; F=6.39; P=0.03), the early apoptosis rates of 3.0, 1.0μmol/L group were higher than that of the control group(all P<0.05), and the early apoptosis rate in the 3.0 μmol/L group was higher than that in the 1.0μmol/L group[(11.83±1.12)% vs.(7.01±1.84)%, t=3.73, P<0.05]. The expression of p65 protein decreased, while both the expressions of caspase-3 and caspase-9 proteins increased after treatment with cryptotanshinone. Conclusion:Cryptotanshinone can significantly inhibit proliferation and induce apoptosis of human bladder carcinoma J82 cells in vitro, probably via suppressing NF-κB signal pathway and activating mitochondrial pathway, respectively.

ABSTRACT

Objective@#To investigate the impact of change of ideal cardiovascular behavior and related factors on healthy vascular aging(HVA).@*Methods@#This study was a multi-center cross-sectional survey. Six thousand three hundred and sixteen participants who underwent at least 2 healthy examinations from 2006 to 2015 at 11 hospitals, including Kailuan Hospital and so on, and examined brachial-ankle pulse wave velocity (baPWV) during 2010 and 2016, with available information about cardiovascular behavior and factors were included. The cardiovascular health score (CHS) was calculated. Basic CHS was collected from the first examination. The second CHS derived from the healthy examination in the same year of baPWV examination. Change of cardiovascular health score (ΔCHS) was calculated. Participants were defined into 5 groups according to ΔCHS, namely ΔCHS≤-2 (n=2 166), ΔCHS=-1 (n=1 284), ΔCHS=0 (n=1 187), ΔCHS=1 (n=860), and ΔCHS≥2 (n=819). Participants′ characteristics, value of baPWV and proportion of HVA were compared among different groups. Multiple logistic regression analysis was used to investigate the association between ΔCHS and HVA. The ΔCHS was recalculated and included in multiple logistic regression analysis model again after each component of the cardiovascular health metrics was removed separately in order to investigate effects of removal factors on HVA by observing changes in effect values.@*Results@#The percentage of the participants with HVA in the group of ΔCHS≤-2, ΔCHS=-1, ΔCHS=0, ΔCHS=1 and ΔCHS≥2 were 23.3%(505/2 166), 27.8%(357/1 284), 28.7%(341/1 187),31.9%(274/860) and 33.9%(278/819), respectively. After adjustment for age, sex, income, education, alcohol consumption and the basic CHS, a significant positive association between ΔCHS and proportion of participants with HVA was observed (OR=1.50, 95%CI 1.44-1.56). Multiple regression analysis after removing each single cardiovascular behavior or factor showed that the OR value decreased as follow systolic blood pressure (OR=1.04, 95%CI 1.00-1.09), fasting blood glucose (OR=1.14, 95%CI 1.09-1.18), physical exercise (OR=1.16, 95%CI 1.11-1.21), salt intake (OR=1.17, 95%CI 1.12-1.22), body mass index (OR=1.18, 95%CI 1.13-1.23), smoking(OR=1.18, 95%CI 1.13-1.23) and total cholesterol (OR=1.20, 95%CI 1.16-1.24).@*Conclusion@#The improvement of every ideal cardiovascular behavior and factor is associated with the increase of the proportion of HVA population.

ABSTRACT

Objective To investigate the correlation of short-term systolic blood pressure variability (SBPV) with esti?mated glomeruar filtration rate (eGFR) in the elderly. Methods In physical examination for the third time of kailuan group, the method of cluster sampling was used to collect randomly retired employees, age≥60 in kailuan group. The 24-hour am?bulatory blood pressure monitoring was given to these objects. Finally, 1 405 participants with integral data were recruited in?to the survey. SBPV indices were standard deviation of systolic blood pressure (SD), variability independent of the mean (VIM), maximum-minimum difference (MMD), and average real variability (ARV). Multivariate stepwise linear regression models were used to analyze the influence of short-term SBPV on eGFR. Results (1) Among 1 405 participants (67.16 ± 5.82) years, 933 individuals (66.4%) were male and 472 (33.6%) were female. (2) Study population were divided into four groups based on the 24-hour mean SBP, daytime mean SBP, night time mean SBP (group 1:mean SBP<120 mmHg, group 2:120≤mean SBP<140 mmHg, group 3:140≤mean SBP<160 mmHg, group 4:mean SBP≥160 mmHg), respectively. Values of SD, MMD and ARV, but not VIM were increased with increased mean SBP. (3) The participants were grouped according to the median SBPV with between-group comparison of the eGFR. The average eGFR levels were lower in the high 24-hour SB?PV group (SD, VIM, MMD and ARV), day-time SBPV group (SD, VIM, MMD and ARV) and night-time SBPV group (SD, MMD and ARV) than those in the low SBPV groups (P<0.05). (4) Multivariate stepwise linear regression showed that eGFR increased with 3 indices of 24-hour SBPV (SD, MMD and ARV) and 2 indices of day-time SBPV (MMD and ARV) but not for night-time SBPV (β=-0.07,-0.11,-0.07,-0.12 and-0.07, respectively). Conclusion There is a certain degree of asso?ciation between short-term SBPV indices and eGFR.

ABSTRACT

Objective: To analyze long-term therapeutic effect and safety of warfarin anticoagulant therapy of different intensity on aged patients with nonvalvular atrial fibrillation (NVAF). Methods: According to age, a total of 197 NVAF patients followed up for five years were divided into advanced aged group [n=65,≥80(85±2.09)years], aged group [n=75, 65-79(76.5±2.27) years] and middle-aged group [n=57, <65(57.4±2.18)]. All enrolled patients received long-term warfarin anticoagulant therapy, advanced aged group and aged group received low intensity anticoagulation, international normalized ratio (INR) was 1.6~2.5, while middle-aged group received standard intensity anticoagulation and the INR was 2.0~3.0. Thrombus events and incidence rates of hemorrhage etc. over five years were compared among three groups, and the safe dose range of warfarin was explored. Results: During five-year follow-up, no acute cerebral infarction occurred in three groups. The bleeding and other adverse reaction among three groups were no significant difference(P>0.05). Compared with middle-aged group, there were significant reductions in warfarin dose [(3.29±0.49) mg/d vs. (2.95±0.38) mg/d, (2.85±0.49) mg/d],INR [(2.54±0.43) vs. (2.20±0.29), (2.16±0.32)] and CHA2DS2-VASc [(3.02±0.89) score vs.( 2.64±0.77) score vs.( 2.33±0.48) score]in aged group and advanced aged group, P<0.01 all; but there were no significant difference between aged group and advanced aged group (P>0.05). There were no significant difference in incidence rates of mild hemorrhage (21.1% vs. 14.7% vs. 24.6%) and severe hemorrhage (1.8% vs. 1.3% vs. 1.5%) among middle-aged group, aged group and advanced aged group, P>0.05 all. Conclusion: When INR is closely monitored, INR controlled within 1.6~2.5, warfarin anticoagulation is safe and effective in aged patients with nonvalvular atrial fibrillation.

ABSTRACT

Objective To investigate the correlation of the supine hypertension (SP) with carotid intima-media thickness (IMT) in the elderly. Methods Kailuan study is a functional community-based cardiovascular risk factor study. From June 2006, there was a physical examination every two years. In the examination, demographic data, smoking, drinking, physical exercise situation and medication situation were recorded. Levels of triglyceride, high sensitivity C-reactive protein, low density lipoprotein and other biochemical indexes were observed. Using cluster random sampling, 3 064 retired employees of 60 years of age or older were selected. A total of 2 464 subjects took part in an additional examination, including the 24-hour ambulatory blood pressure monitoring, brachial-ankle pulse wave velocity, blood pressure of different positions and urine albumin. Multiple linear regression was used to analyze the correlation between supine systolic blood pressure (SBP) and IMT. Multivariate Logistic regression was used to analyze the effect of SP on IMT. Results (1) Among 2 220 participants (67.29±6.09) years, 1 463 (65.9%) individuals were male and 757 (34.1%) were females, and the average IMT was (0.92 ± 0.18) mm. (2) There was a positive correlation between supine SBP and IMT (r=0.175, P<0.01). (3) After adjusting the confounds, supine SBP was significantly associated with IMT, with an increase of 1 SD (+20.42 mmHg, 1 mmHg=0.133 kPa) in SBP corresponding to an increase of IMT by 0.01 mm (P<0.01). (4) Multiple Logistic regression analysis showed that after adjusting for sitting SBP, age, gender and other factors, SP was still a risk factor of increased IMT (OR=1.37, 95%CI:1.03-1.80), and independent of sitting SBP. Conclusion The supine hypertension is a risk factor of increased IMT, and independent of sitting SBP.

The observation population was divided into three groups according to the third tertiles of the time systolic blood pressure variability: the first point(<9.09 mmHg (1 mmHg=0.133 kPa)), second point (≥9.09 mmHg, and <14.29 mmHg), and third point (≥14.29 mmHg). Multivariate logistic regression analysis was used to analyze the correlation between long time systolic blood pressure variability and short time systolic blood pressure.</p><p><b>RESULTS</b>(1) The participants' age were (67.0±5.7) years old (284 women). (2) The 24 hours and daytime SSD were (14.7±4.0) mmHg, (14.7±3.5) mmHg, (15.7±4.4) mmHg (P=0.010) and (14.1±4.4) mmHg, (14.2±3.5) mmHg and (15.4±4.6) mmHg (P<0.001) according to the tertiles of long time systolic blood pressure variability, respectively, nighttime SSD were (12.0±4.4) mmHg, (11.8±4.8) mmHg and (11.9±4.9) mmHg (P=0.900).

ABSTRACT

<p><b>BACKGROUND</b>Blood pressure variability (BPV) is a reliable prognostic factor for cardiovascular events. Currently there is a worldwide lack of large sample size studies in visit-to-visit BPV. Based on the Kailuan Study, we analyzed the visit-to-visit BPV of patients to investigate the range and influencing factors of BPV.</p><p><b>METHODS</b>In 11 hospitals in the Kailuan Company, 4 441 patients received routine health checkups. Physical examination measured blood pressure (BP), body height, body weight, and waist circumference, and body mass index was calculated. Blood samples were analyzed for plasma total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), fasting blood glucose (FBG), and high-sensitivity c-reactive protein (hs-CRP).</p><p><b>RESULTS</b>The effect of gender on systolic BPV was investigated. The average systolic BPV was 10.35 mmHg (1 mmHg = 0.133 kPa) overall, 10.54 mmHg in males and 10.06 mmHg in females. Multivariate Logistic regression analysis revealed that the age (RR = 1.022), systolic BP (SBP, RR = 1.007), LDL-C (RR = 1.098), and history of hypertension (RR = 1.273) were significant risk factors for higher systolic BPV. We found that aging (RR = 1.022), increased SBP (RR = 1.007), and a history of hypertension (RR = 1.394) were determinants of systolic BPV in males. The risk factors for systolic BPV of females were aging (RR = 1.017), increased SBP (RR = 1.009), increased LDL (RR = 1.136), and increased TG (RR = 1.157).</p><p><b>CONCLUSION</b>Our findings indicated that the systolic BPV is closely associated with age, SBP and history of hypertension.</p>

ABSTRACT

Objective To investigate the association between left ventricular diastolic function and arterial stiffness in patients with type 2 diabetes mellitus. Methods One hundred and two patients with type 2 diabetes( diabetic group),and 126 non-diabetic patients( control group) were selected from Jan. 2012 to Dec. 2013 in the Beijing Military General Hospital. The clinical features were recorded and free blood glucose (FBG ),blood lipids were measured. Cardio ankle vascular index( CAVI ) was measured by VS-1000 arteriosclerosis detector. Ultrasound heartbeat diagram was used to determine the left ventricular diastolic function indexes including the left atrial diameter(LAD),left ventricular early diastolicpeak velocity(E),left ventricular diastolic peak velocity(A),E/ A ratio and E peak deceleration time(EDT). Results The level of LAD,A, EDT,CAVI in diabetic patients were(39. 5 ± 5. 3)mm,(76. 6 ± 13. 5)cm/ s,(206. 6 ± 56. 3)ms,(9. 6 ± 1. 1)respectively,higher than those in control group((34. 4 ± 4. 2)mm,(71. 3 ± 13. 4)cm/ s,(185. 5 ± 34. 4)ms,(8. 5 ± 0. 9)). And E,E/ A level in diabetic group were(56. 6 ± 20. 4)cm/ s and(0. 73 ± 0. 21),significantly lower than the control group((67. 5 ± 16. 4)cm/ s and(0. 96 ± 0. 26)). The differences between the two groups were significant(P = 0. 001,0. 004,0. 002,0. 001,0. 001,0. 001). After adjusting the factors including body mass index and triglyceride,CAVI was negatively correlated with E/ A(r = - 0. 339,P< 0. 05))and positively correlated with EDT(r = 0. 314,P < 0. 05). Conclusion The diabetic patients with lower diastolic function and higher arterial stiffness,and the two factors are negatively correlation.

ABSTRACT

As a fundamental component of the host cellular cytoskeleton, actin is routinely engaged by infecting viruses. Furthermore, viruses from diverse groups, and infecting diverse hosts, have convergently evolved an array of mechanisms for manipulating the actin cytoskeleton for efifcacious infection. An ongoing chorus of research now indicates that the actin cytoskeleton is critical for viral replication at many stages of the viral life cycle, including binding, entry, nuclear localization, genomic transcription and reverse transcription, assembly, and egress/dissemination. Speciifcally, viruses subvert the force-generating and macromolecular scaffolding properties of the actin cytoskeleton to propel viral surifng, internalization, and migration within the cell. Additionally, viruses utilize the actin cytoskeleton to support and organize assembly sites, and eject budding virions for cell-to-cell transmission. It is the purpose of this review to provide an overview of current research, focusing on the various mechanisms and themes of virus-mediated actin modulation described therein.

ABSTRACT

Objective: To study therapeutic effects of simvastatin on vascular endothelial cell dysfunction in patients with coronary heart disease (CHD). Methods: According to LDL-C level, a total of 90 CHD patients were divided into simvastatin 20mg group (n=37, LDL-C≥2.5mmol/L), simvastatin 10mg group (n=35, 1.8mmol/L≤LDL-C0.05 all; Compared with routine treatment group, there were significant improvement in FMD [(6.01±0.49)% vs. (9.01±0.39)% vs. (9.01±0.47)%,P0.05 all. Conclusion: Simvastatin can increase NO concentration and improve vascular endothelial cell dysfunction in CHD patients. Its mechanism may be related with lipid-lowering effect, but independent of its lipid-lowering effect
