ABSTRACT

Objective:To investigate the clinical value of spherical lens with 0.05 D intervals in optometry for small incision lenticule extraction (SMILE) in myopic eyes.Methods:A randomized controlled clinical study was conducted.Sixty patients (120 eyes) with low to moderate myopia and myopic astigmatism who underwent SMILE in the 989th Hospital of the PLA from June 2021 to February 2022 were enrolled.The patients were randomly divided into 0.05 D interval group (optometry with spherical lens at 0.05 D interval) and 0.25 D interval group (optometry with spherical lens at 0.25 D interval), with 30 cases (60 eyes) in each group.There was no significant difference in matched age, sphericity, cylindricity, and best corrected visual acuity (BCVA) (all at P>0.05). The preoperative monocular red-green balance, 1- and 3-month postoperative monocular red-green balance, uncorrected visual acuity and spherical equivalent of both groups were compared.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of the 989th Hospital of the PLA (No.WZLL-2021-034). Written informed consent was obtained from each subject before any medical examination. Results:The preoperative red-green balance rate in 0.05 D interval group was 95.00%(57/60), which was higher than 35.00%(21/60) in 0.25 D interval group, showing a statistically significant difference ( Wald χ2=17.642, P<0.001). The 1- and 3-month postoperative red-green balance rates in 0.05 D interval group were 63.33%(38/60) and 56.67%(34/60), which were higher than 23.33%(14/60) and 21.67%(13/60) in 0.25 D interval group respectively, showing statistically significant differences ( Wald χ2=9.137, P=0.003; Wald χ2=7.483, P=0.006). The 1- and 3-month postoperative visual acuity in 0.05 D interval group were -0.1(-0.1, -0.1) and -0.1(-0.1, -0.1), which were higher than 0.0(-0.1, 0.0) and -0.1(-0.1, 0.0) in 0.25 D interval group respectively, showing statistically significant differences ( Wald χ2=11.624, P=0.001; Wald χ2=12.841, P<0.001). The 1- and 3-month postoperative spherical equivalent were -0.07(-0.25, 0.13)D and -0.13(-0.25, 0.13)D in 0.05 D interval group, which were higher than -0.13(-0.38, 0.25)D and -0.13(-0.38, 0.25)D in 0.25 D interval group respectively, showing no statistically significant difference between the two groups ( Wald χ2=0.029, P=0.866; Wald χ2=0.189, P=0.664). Conclusions:Compared with spherical lens at 0.25 D interval, 0.05 D interval can improve the accuracy of preoperative and postoperative red-green balance rate and postoperative visual acuity in patients with low to moderate myopia who undergo SMILE.

ABSTRACT

Objective@#To understand the public health emergency response capacity in primary and secondary schools, and to explore the problems and challenges in the prevention and control of public health emergency in primary and secondary schools for specific strategies.@*Methods@#By using the stratified group sampling method, a questionnaire survey on general situation, knowledge, attitude and training, as well as public health emergencies response capacity among 2 988 teachers or leaders responsible for school emergency response in primary and secondary schools from Beijing, Chongqing and Yunnan.@*Results@#Participants varied on their positions, titles, educational background and knowledge accuracy. Higher knowledge accuracy was associated with higher educational background ( χ 2=50.73-203.36, P < 0.05 ). The implementation of regular public health emergency related programs was poorly conducted in high schools (50.0%). Urban schools (42.0%) had higher proportion of qualified health care professionals than rural schools (18.2%), and private schools (48.5%) was higher than public schools (24.7%). The primary challenges included the shortage of guidance from professionals and the lack of related testing equipment (84.91%, 74.03%).@*Conclusion@#Although the ability of emergency handling of public health emergencies in schools in the three regions is advancing with the times, there are still many deficiencies, some omissions in the mastery of knowledge. It is suggested to inerease pre service and special training of school health work CDC should strengthen technical guidance and work supervision of infectious disease management in schools.

ABSTRACT

ObjectiveTo explore the mechanism of Qigesan (QGS) in intervening in the migration and invasion of esophageal carcinoma TE-1 cells. MethodMicroarray technology was used to screen differentially expressed genes (DEGs) in the normal group and the QGS group, and the ontological functions and signaling pathways of DEGs were analyzed. The thiazolyl tetrazolium (MTT) assay was used to detect the effect of QGS on the viability of TE-1 cells. In the subsequent experiments for verification, a blank group, a transforming growth factor-β1 (TGF-β1) group, a TGF-β1 + QGS group, and a TGF-β1 + SB431542 group were set up. The cell morphology in each experimental group was observed by microscopy. The migration and invasion abilities of cells were detected by wound healing assay, and the mRNA expression levels of E-Cadherin, vimentin, Smad2, and Smad7 were detected by Real-time quantitative polymerase chain reaction (Real-time PCR). The protein expression of E-Cadherin, vimentin, p-Smad2/3, Smad2/3, and Smad7 was detected by Western blot. ResultThere were 1 487 DEGs between the QGS group and the blank group, including 1 080 down-regulated ones (accounting for 72.63%) and 407 up-regulated ones. The down-regulated genes were mainly involved in biological processes such as cytoskeletal protein binding, ATP binding, adenylate nucleotide binding, and adenylate ribonucleotide binding, and the involved Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways included TGF-β signaling pathway, cell cycle, extracellular matrix-receptor interaction protein, tumor pathways, and oocyte meiosis. The up-regulated genes were mainly involved in RNA binding, DNA binding, transcriptional regulator activity, transcriptional activator activity, and nucleotide binding, and the KEGG pathways involved mainly included mitogen-activated protein kinase (MAPK) signaling pathway, bladder cancer, renal cell carcinoma, cancer pathways, and p53 signaling pathway. Compared with the blank group, the inhibition rate of cell viability of TE-1 cells increased after QGS (20, 30, 40, 60, 80 mg·L-1) intervention for 12, 24, 36, 48, 60 h (P<0.05), and the inhibition rate was time- and dose-dependent. Compared with the blank group, the TGF-β1 group showed lengthened cells with fibroblast phenotype. Compared with the TGF-β1 group, the TGF-β1 + QGS group showed shortened cells with normal morphology and epithelial phenotype. The cell morphology in the TGF-β1 + SB431542 group was similar to that of the TGF-β1 + QGS group. Compared with the blank group, the TGF-β1 group showed potentiated ability of cell migration and invasion (P<0.05). Compared with the TGF-β1 group, the TGF-β1 + QGS group and the TGF-β1 + SB431542 group showed inhibited and weakened migration and invasion abilities of cells (P<0.05). However, there was no significant difference in migration and invasion abilities between the TGF-β1 + QGS group and the TGF-β1 + SB431542 group. The mRNA expression levels of vimentin and Smad2 in the TGF-β1 group were higher (P<0.05), and the mRNA expression levels of E-Cadherin and Smad7 were lower (P<0.05) than those in the blank group. Compared with the TGF-β1 group, the TGF-β1 + QGS group and the TGF-β1+ SB431542 group exhibited decreased expression levels of vimentin and Smad2 mRNA (P<0.05), and elevated expression levels of E-Cadherin and Smad7 mRNA (P<0.05). Compared with the blank group, the TGF-β1 group showed up-regulated protein expression levels of vimentin, p-Smad2/3, and Smad2/3 (P<0.05), and reduced protein expression levels of E-Cadherin and Smad7 (P<0.05). Compared with the TGF-β1 group, the TGF-β1 + QGS group and the TGF-β1 + SB431542 group displayed decreased protein expression levels of vimentin, p-Smad2/3, and Smad2/3 (P<0.05), and increased protein expression levels of E-Cadherin and Smad7 (P<0.05). ConclusionThe ethyl acetate extract of QGS inhibits the epithelial-mesenchymal transition (EMT) of TE-1 cells through the TGF-β1 pathway to reduce the migration and invasion of TE-1 cells.

ABSTRACT

Objective@#To understand parents attitudes towards adolescent sexual education in Baoshan City of Yunnan Province, and to explore the correlation between attitudes and their proactive behavior in adolescent sexual education, so as to provide reference for improving parents initiative in adolescent sexual health education.@*Methods@#From November to December 2022, a stratified random cluster sampling method was used to select 7 389 parents of students from 35 primary, middle, and high schools in Baoshan City of Yunnan Province for a questionnaire survey on adolescent sexual health education in parents schools. Chi-square tests were conducted to compare the attitudes of parents towards sexual health education among different groups and their proactive behavior in providing sexual health education to their children. A multivariate Logistic regression model was used to analyze the correlation between parents attitudes towards sexual education and proactive sexual health education.@*Results@#Totally 43.17% ( 3 190 ) of parents had a more open attitude towards sex education for their children, with parents of girls, parents of elementary school students, mothers, <30 years old, junior high school education, workers, service personnel, married, harmonious relationships with their children and democratic parents had a higher rate of actively providing sex education for their children ( χ 2=4.65, 401.92, 23.53 , 197.50, 38.18, 13.65, 6.54, 8.07, 32.17, 96.58, P <0.05). Parents with a more conservative attitude towards sex education and parents of boys were negatively correlated with parents actively providing adolescent sexual health education to their children ( OR =0.86, 0.38, P <0.05). Parents who were <30, 30-<40, 40-50 years old, individuals/businesses, married, divorced, had a good and decent relationship with their children were positively correlated with their parents proactive adolescent sexual health education for their children ( OR =1.50, 1.90, 1.37, 1.22, 1.60, 1.32, 1.94, 1.53, P <0.05).@*Conclusion@#A more open attitude towards adolescent sexual health education can serve as a predictive factor for proactive adolescent sexual health education. In order to increase the rate of family sexual health education, it is recommended to enhance parents awareness of their responsibility for their children s sexual health education, promote harmonious parent-child relationships between parents and children, and communicate with their children with an open attitude.

ABSTRACT

OBJECTIVE To explore the mechanism of oridon in(Ori)reversing the drug resistance of breast cancer cell MCF-7 to fulvestrant (Ful). METHODS Ful-resistant breast cancer cell strains MCF- 7/Ful were induced and constructed in vitro . The relative cell viability of MCF- 7 cells and MCF- 7/Ful cells was detected by MTT assay ,inhibitory rate of Ori to MCF- 7/Ful cells was also detected. CompuSyn software was used to analyze the synergistic effect of Ori and Ful. MCF- 7/Ful cells were randomly divided into blank control group ,Ful group (5 μmol/L),Ori group (8 μmol/L),Ful(5 μmol/L)+Ori(8 μmol/L)group. The phosphorylation of phosphatidylinositol 3 kinase(PI3K)/protein kinase B (Akt)signaling pathway related protein in each group was detected by Western blot. MCF-7/Ful cells were used to prepare drug resistance model of transplanted tumor in nude mice,and they were randomly divided into blank control group ,Ful group (80 μmol/g),Ori group (50 μmol/g),Ful(80 μmol/g)+ Ori(50 μmol/g)group. The tumor weight and tumor inhibition rate were calculated ,to verify the reversal effect of Ori and Ful in vivo. RESULTS MTT assay showed that when Ful ≥10 μmol/L,the relative cell viability of MCF- 7/Ful cells was significantly higher than that of MCF- 7 cells(P<0.05),and the drug resistance was significantly enhanced ;Ori had a significant inhibitory effect on MCF- 7/Ful cells ,the inhibition rate of Ori combined with Ful to MCF- 7/Ful cells was significantly increased (P<0.05 or P<0.01),and the effect of reversing drug resistance was significantly increased . The results of Western blot showed that compared with Ful group ,the phosphorylation levels of PI 3K and Akt protein in Ful+Ori group were significantly decreased (P<0.05 or P< 0.01). In vivo results showed that the tumor volume and mass of Ful+Ori group were significantly decreased ,and the tumor inhibition rate was (63.90±4.11)%,which was significantly higher than that of Ful group (P<0.01). CONCLUSIONS Ori can reverse drug resistance of breast cancer cell MCF- 7 to Ful , and this effect may be through regulating PI 3K/Akt signaling pathway.

ABSTRACT

Objective: To explore the relationship between the ideal cardiovascular health behaviors and factors and newonset heart failure. Methods: It was a prospective cohort study. People who attended the 2006-2007 physical examination of Kailuan Group Company and with complete data of cardiovascular behaviors and related factors were eligible for this study. A total of 95 167 participants who were free of valvular heart diseases, congenital heart diseases and a prior history of heart failure were included. Basic cardiovascular health score (CHS) of each participant was calculated. Participants were divided into 3 groups according to CHS. Group 1:CHS<8 (n=26 640), Group 2:8≤CHS<10 (n=35 230), Group3:CHS≥10 (n=33 297). The general clinical data and laboratory test results were collected. The outcome was defined as the first occurrence of heart failure at the end of followup(December 31, 2016). Cox regression model was used to determine the association between baseline CHS and the risk of newonset heart failure. Results: After a median followup of 10.3 years, the incidence of newonset heart failure in the group of CHS<8,8≤CHS<10,CHS≥10 were 2.7%(729/26 640), 1.8%(651/35 230) and 1.1%(360/33 297),respectively. After adjustment for age, sex, history of myocardial infarction, history of atrial fibrillation, income, alcohol consumption, education and the use of antihypertensive, cholesterol-lowering, glucose-lowering medications, compared with the group of CHS<8, the Cox regression model showed that HRs of the group of 8≤CHS<10 and CHS≥10 were 0.68 (95%CI 0.61-0.75), 0.49 (95%CI 0.43-0.55), respectively. Cox regression analysis after removing each single cardiovascular behavior or factor showed that the HR value range ability was as follows:systolic blood pressure(HR=0.78,95%CI 0.74-0.82), body mass index(HR=0.78,95%CI 0.74-0.82), fasting blood glucose (HR=0.77,95%CI 0.73-0.81), total cholesterol(HR=0.76,95%CI 0.72-0.80), physical exercise(HR=0.72,95%CI 0.69-0.76), smoking(HR=0.75,95%CI 0.71-0.79) and salt intake(HR=0.73,95%CI 0.69-0.77). Conclusion: CHS is negatively associated with the risk of newonset heart failure, and there is a dose-response relationship between the two indexes.

ABSTRACT

Objective:To analyze the epidemiological characteristics and tendency of hemorrhagic fever with renal syndrome (HFRS) in Xi'an, master its popular and development laws, and provide scientific basis for formulating targeted prevention and control measures.Methods:The retrospective method was used to collect HFRS epidemic data and demographic data from 2009 to 2018 in Xi'an. The descriptive epidemiological method was used to analyze the three distributions (time, region, population distributions) of HFRS.Results:There were 8 710 HFRS cases in Xi'an from 2009 to 2018, with an average annual incidence of 10.13/100 000 and an average annual mortality rate of 0.08/100 000; the incidence of HFRS had decreased year by year since the peak incidence in 2010 (19.46/100 000), and had rebounded in 2017 (9.14/100 000), 2018 (9.04/100 000). The time distribution of the onset of HFRS was bimonthly, with peak in autumn and winter (October to January of following year) each year, accounting for 74.08% (6 452/8 710) of the total number of cases; the peak in spring and summer (May to July) accounted for 14.33% (1 248/8 710). HFRS cases were mainly concentrated in Chang'an District (2 446 cases), Zhouzhi County (1 494 cases), Hu County (1 170 cases), and Lintong District (940 cases), accounting for 69.46% (6 050/8 710). The age of onset of HFRS cases was mainly concentrated in 15-59 years old, accounting for 74.06% (6 451/8 710); the incidence rate in males was 14.77/100 000, in females was 5.25/100 000, the difference was statistically significant between gender (χ 2=1 921.42, P < 0.05); the occupational distribution was mainly farmers, accounting for 68.38% (5 956/8 710). Conclusions:From 2009 to 2016, the HFRS epidemic situation in Xi'an has showed a downward trend, and the incidence of HFRS has rebounded in 2017-2018. Xi'an should continue to take active and effective comprehensive measures to intervene to further realize effective control of HFRS.

ABSTRACT

Objective:To explore the underlying protective mechanism of Kaixinsan on learning, memory, and synaptic function in APP/PS1 mice. Method:Sixty APP/PS1 mice were randomly divided into a model group, a donepezil (2 mg·kg<sup>-1</sup>·d<sup>-1</sup>) group, and low- (0.7 g·kg<sup>-1</sup>·d<sup>-1</sup>), medium- (1.4 g·kg<sup>-1</sup>·d<sup>-1</sup>), and high-dose (2.8 g·kg<sup>-1</sup>·d<sup>-1</sup>) Kaixinsan groups, and the wild-type mice of the same age in the same litter were assigned to the normal group, with 12 mice in each group. After continuous intragastric administration for two months, the Morris water maze experiment was performed. The ultrastructure of hippocampal neurons was observed by transmission electron microscopy. The colorimetric assay was used to detect serum content of acetylcholine (ACh), choline acetyltransferase (ChAT), acetylcholinesterase (AChE), and levels of hippocampal reactive oxygen species (ROS), malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px). Real-time fluorescence-based quantitative polymerase chain reaction (Real- time PCR) was used to detect the mRNA expression of hippocampal brain-derived neurotrophic factor (BDNF), beta-nerve growth factor (NGFB), discs large homolog (DLG)2, DLG4, and synaptophysin (SYP). Result:Compared with the normal group, the model group showed prolonged escape latency, reduced number of crossing platforms, shortened stay in the target quadrant (<italic>P</italic><0.01), decreased number of mitochondria with different shapes and irregular arrangement, some swollen and deformed mitochondria with broken mitochondrial cristae, endolysis, and cytoplasm vacuole, and more cell debris. Additionally, the model group also displayed reduced serum levels of ACh and ChAT, increased AChE (<italic>P</italic><0.01), elevated hippocampal ROS and MDA (<italic>P</italic><0.05,<italic>P</italic><0.01), declining SOD and GSH-Px (<italic>P</italic><0.01), and diminished hippocampal BDNF, NGFB, DLG2, DLG4, and SYP mRNA levels (<italic>P</italic><0.05,<italic>P</italic><0.01). Compared with the model group, the donepezil group, and the medium- and high-dose Kaixinsan groups showed shortened escape latency, increased number of crossing platforms, prolonged stay in the target quadrant (<italic>P</italic><0.05,<italic>P</italic><0.01), improved mitochondrial damage with a regular shape (mainly oval shape), relieved mitochondrial swelling and deformation, and clear mitochondrial cristae. Furthermore, the donepezil group, and the medium- and high-dose Kaixinsan groups also exhibited increased serum ACh and ChAT levels (<italic>P</italic><0.05,<italic>P</italic><0.01), blunted AChE activity (<italic>P</italic><0.05), reduced hippocampal ROS level (<italic>P</italic><0.05,<italic>P</italic><0.01), declining MDA level (<italic>P</italic><0.05), potentiated SOD and GSH-Px activities, and up-regulated hippocampal BDNF, NGFB, DLG2, DLG4, and SYP mRNA levels (<italic>P</italic><0.05,<italic>P</italic><0.01). In the low-dose Kaixinsan group, the stay time in the target quadrant was prolonged and the expression of hippocampal SYP mRNA was elevated significantly (<italic>P</italic><0.05). There was no statistical difference in swimming speed between the groups. Conclusion:Kaixinsan can improve the learning and memory ability of APP/PS1 mice by increasing the expression of synaptic plasticity-related proteins, reducing the ultrastructural damage to hippocampal neurons, resisting oxidative stress, and regulating cholinergic neurotransmitters, thereby exerting neuroprotective effects.

ABSTRACT

OBJECTIVE:To study the effects of Plantago asiatica polysaccharide on the proliferation ,migration and invasion of breast cancer cells ,and to investigate its mechanism preliminarily. METHODS :Using human breast cancer cell MDA-MB- 231 as subjects ,MTT method was adopted to detect the effects of different concentrations of P. asiatica polysaccharide(8,16,32,64 mg/L)on the cell proliferation ability ,and survival rate of the cells was calculated. Scratch test and Transwell invasion test were used to detect the effects of different concentrations of P. asiatica polysaccharide(8,16 mg/L)on cell migration ability and invasion ability. Western blot assay was used to detect the expression of epithelial-mesenchymal transition (EMT)-related proteins [matrix metalloproteinase- 2(MMP-2),MMP-9,E-cadherin,N-cadherin,vimentin]. RESULTS :Results of MTT assay showed that survival rate of the cells in 32,64 mg/L P. asiatica polysaccharide groups were significantly lower than control group (P<0.05 or P<0.01),so that 8,16 mg/L,which did not affect the cell survival rate ,were used as the follow-up drug concentrations. Compared with control group ,relative mobility (12,24 h),relative invasion rate and relative expression of MMP- 2,MMP-9, N-cadherin and vimentin protein were decreased significantly in 8,16 mg/L P. asiatica polysaccharide groups (P<0.05 or P< 0.01),while relative expression of E-cadherin protein was increased significantly (P<0.05 or P<0.01). CONCLUSIONS :P. asiatica polysaccharide can inhibit the proliferation of breast cancer cells MDA-MB- 231,and inhibit the migration and invasion of the cells by regulating the expression of metastasis and EMT-related proteins.

ABSTRACT

Dyslipidemia is a disease of lipid metabolism. At present, the prevalence of dyslipidemia in adults in China is as high as 40.40%. In the United States, there are more than 100 million individuals with abnormal low-density lipoprotein cholesterol (LDL-C), and the incidence rate is increasing year by year and showing a trend of becoming younger. Dyslipidemia is closely related to a variety of diseases such as fatty liver, atherosclerosis , hypertension, coronary heart disease, diabetes, and stroke. It has now developed into a global public health problem that seriously threatens human life and health. Modern medicine believes that its pathogenesis is complicated and is related to abnormal glucose and lipid metabolism, insulin resistance (IR) and other factors. Chinese medicine ascribes it to primary asthenia-secondary sthenia syndrome, which is closely related to the liver, spleen, and kidney. It is believed that excessive fat and grease can cause phlegm and cause many diseases. In terms of its treatment, western medicine mainly uses statin chemical synthesis preparations, with stable therapeutic effect, but many adverse reactions such as myalgia, myositis, rhabdomyolysis and acute renal injury are the main factors restricting its clinical application. Traditional Chinese medicine (TCM) has a long history, and multi-pathway, multi-target, multi-level regulation of dyslipidemia, few adverse reactions and low drug dependence are the principal advantages of TCM in treating dyslipidemia. At present, there are more and more researches on the prevention and treatment of dyslipidemia by TCM, but they are mainly focused on the observation of curative effect and the summary of prescription, and there are relatively few in-depth discussion and summary of the mechanism of TCM. Through comprehensively retrieving and collating the relevant domestic and foreign literatures in the past five years, we reviews from the perspective of effective ingredients, therapeutic pathways, and targets of action, and comprehensively introduces the latest research progress of TCM on the mechanism of regulating dyslipidemia, and put forward some suggestions for the possible research direction in the future, in order to provide new ideas and theoretical basis for TCM in clinical prevention and treatment of this disease.

ABSTRACT

Objective: To explore the clinical characteristics and prognosis of the new coronavirus 2019-nCoV patients combined with cardiovascular disease (CVD). Methods: A retrospective analysis was performed on 112 COVID-19 patients with CVD admitted to the western district of Union Hospital in Wuhan, from January 20, 2020 to February 15, 2020. They were divided into critical group (ICU, n=16) and general group (n=96) according to the severity of the disease and patients were followed up to the clinical endpoint. The observation indicators included total blood count, C-reactive protein (CRP), arterial blood gas analysis, myocardial injury markers, coagulation function, liver and kidney function, electrolyte, procalcitonin (PCT), B-type natriuretic peptide (BNP), blood lipid, pulmonary CT and pathogen detection. Results: Compared with the general group, the lymphocyte count (0.74 (0.34, 0.94)×109/L vs. 0.99 (0.71, 1.29)×109/L, P=0.03) was extremely lower in the critical group, CRP (106.98 (81.57, 135.76) mg/L vs. 34.34 (9.55,76.54) mg/L, P<0.001) and PCT (0.20 (0.15,0.48) μg/L vs. 0.11 (0.06,0.20) μg/L, P<0.001) were significantly higher in the critical group. The BMI of the critical group was significantly higher than that of the general group (25.5 (23.0, 27.5) kg/m2 vs. 22.0 (20.0, 24.0) kg/m2,P=0.003). Patients were further divided into non-survivor group (17, 15.18%) group and survivor group (95, 84.82%). Among the non-survivors, there were 88.24% (15/17) patients with BMI> 25.0 kg/m2, which was significantly higher than that of survivors (18.95% (18/95), P<0.001). Compared with the survived patients, oxygenation index (130 (102, 415) vs. 434 (410, 444), P<0.001) was significantly lower and lactic acid (1.70 (1.30, 3.00) mmol/L vs. 1.20 (1.10, 1.60) mmol/L, P<0.001) was significantly higher in the non-survivors. There was no significant difference in the proportion of ACEI/ARB medication between the critical group and the general group or between non-survivors and survivors (all P>0.05). Conclusion: COVID-19 patients combined with CVD are associated with a higher risk of mortality. Critical patients are characterized with lower lymphocyte counts. Higher BMI are more often seen in critical patients and non-survivor. ACEI/ARB use does not affect the morbidity and mortality of COVID-19 combined with CVD. Aggravating causes of death include fulminant inflammation, lactic acid accumulation and thrombotic events.

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 evaluate the safety and effectiveness of endovascular balloon dilatation in removing incarcerated tunnel cuffed catheter (TCC) . Methods The clinical data and the imaging materials of 4 hemodialysis patients with incarcerated TCC, who received endovascular balloon dilatation at Taizhou Hospital of Zhejiang Province, China, during the period from January 2017 to March 2018, were retrospectively analyzed. After the treatment, the patient's vital signs were monitored, and the procedure-related complications such as hemopneumothorax, subcutaneous hematoma, arrhythmia, etc. were documented. Results The mean age of the 4 patients was (73.3±6.4) years. The average indwelling time of TCC was 5.5 years (4-8 years) . Successful treatment of incarcerated TCC was achieved in all 4 patients. In one patient, both 5-mm and 6-mm balloons were used to simultaneously dilate the dual cavities of TCC.Temporary arrhythmia occurred in one patient during operation. No serious postoperative complications occurred. Conclusion For the remove of long-term indwelling incarcerated TCC, endovascular balloon dilatation is minimally-invasive, safe and effective, although more researches are needed to further confirm its safety and reliability.

ABSTRACT

OBJECTIVE@#To observe the effect of Quyu Chencuo Formula (, QCF) on renal fibrosis in rats with obstructive nephropathy.@*METHODS@#Twenty-four rats were randomly divided into three groups, 4 for sham operation as the control group, 10 for unilateral ureteral obstruction (UUO) model group, and the rest 10 for QCF treating UUO model group. All rats were sacrificed under 3% pentobarbital (50 mg/kg) anesthesia on the 14th day after surgery, then the right kidney samples of rats were harvested for hematoxylin eosin (HE) staining and Masson staining to observe the renal pathological changes. Immunohistochemistry and Western blotting were used to examine the expression of transforming growth factor β1 (TGF-β1), and real-time polymerase chain reaction (RT-PCR) was employed to examine the expressions of TGF-β1, α-smooth muscle actin (α-SMA) and E-cadherin mRNA.@*RESULTS@#HE and Masson staining showed that the renal interstitial of the rats in the control group had no significant fibrotic lesion; in the model group, there were obvious interstitial fibrosis; for the QCF group, there were epithelial cell necrosis, infiltration of lymphocytes and mononuclear cells, aggravated interstitial fibrosis in varied degrees, but the pathological changes were less in the QCF group than in the model group. The immunohistochemistry and Western blotting results showed that the TGF-β1 expression was increased significantly in the model group, while decreased significantly in the QCF group (P<0.05); RT-PCR showed that the mRNA expression of α-SMA and TGF-β1 increased significantly in the model group, while both were significantly decreased in the QCF group compared with the model group (P<0.05). The mRNA expression of E-cadherin was decreased significantly in the model group, and it was significantly increased in the QCF group as compared with the model group (P<0.05).@*CONCLUSION@#QCF may improve renal fibrosis by regulating the expressions of TGF-β1, α-SMA and E-cadherin, and prevent the progress of kidney fibrosis.

ABSTRACT

OBJECTIVE@#To investigate the impact of Qing'e Pill (, QEP) on the cancellous bone microstructure and its effect on the level of β-catenin in a mouse model of postmenopausal osteoporosis.@*METHODS@#Ninety-six 8-week-old specific pathogen free C57BL/6 mice were randomly divided into 4 groups (24/group): sham, ovariectomised osteoporosis model, oestradiol-treated, and QEP-treated groups. Three months after surgery, the third lumbar vertebra and left femur of the animals were dissected and scanned using micro-computed tomography (micro-CT) to acquire three-dimensional (3D) parameters of their cancellous bone microstructure. The impact of ovariectomy, the effect of oestradiol and QEP intervention on cancellous bone microstructure, and the expression of β-catenin were evaluated.@*RESULTS@#The oestradioland the QEP-treated groups exhibited a significant increase in the bone volume fraction, trabecular number, trabecular thickneßs, bone surface to bone volume ratio (BS/BV), and β-catenin expression compared with those of the model group (P <0.05). In contrast, the structure model index, trabecular separation, and BS/BV were significantly decreased compared with those of the ovariectomised osteoporosis model group (P <0.05). No differences were observed in the above parameters between animals of the QEP- and oestradiol-treated groups.@*CONCLUSIONS@#The increased β-catenin expression may be the mechanism underlying QEP's improvement of the cancellous bone microstructure in ovariectomised mice. Our findings provide a scientific rationale for using QEP as a dietary supplement to prevent bone loss in postmenopausal women.

ABSTRACT

The subtype H9N2 avian influenza virus greatly threatens the Chinese poultry industry, even with annual vaccination. Waterfowl can be asymptomatically infected with the H9N2 virus. In this study, three H9N2 virus strains, designated A/Goose/Jiangsu/YZ527/2011 (H9N2, Gs/JS/YZ527/11), A/Goose/Jiangsu/SQ119/2012 (H9N2, Gs/JS/SQ119/12), and A/Goose/Jiangsu/JD564/2012 (H9N2, Gs/JS/JD564/12), were isolated from domestic geese. Molecular characterization of the three isolates showed that the Gs/JS/YZ527/11 virus is a double-reassortant virus, combining genes of A/Quail/Hong Kong/G1/97 (H9N2, G1/97)-like and A/Chicken/Shanghai/F/98 (H9N2, F/98)-like; the Gs/JS/SQ119/12 virus is a triple-reassortant virus combining genes of G1/97-like, F/98-like, and A/Duck/Shantou/163/2004 (H9N2, ST/163/04)-like. The sequences of Gs/JS/JD564/12 share high homology with those of the F/98 virus, except for the neuraminidase gene, whereas the internal genes of Gs/JS/YZ527/11 and Gs/JS/SQ119/12 are closely related to those of the H7N9 viruses. An infectivity analysis of the three isolates showed that Gs/JS/SQ119/12 and Gs/JS/YZ527/11 replicated well, with seroconversion, in geese and chickens, the Gs/JS/JD564/12 did not infect well in geese or chickens, and the F/98 virus only infected chickens, with seroconversion. Emergence of these new reassortant H9N2 avian influenza viruses indicates that these viruses can infect both chicken and goose and can produce different types of lesions in each species.

ABSTRACT

Aim To investigate the effects of intestinal infection induced by Cryptosporidium parvum on the ex-pression pattern of SSTR4 and SSTR5 subtype, and to examine the effect of octreotide on modulating short-term and long-term SSTR4 and SSTR5 subtype expres-sion in rat jejunum. Methods Five-day-old suckling Sprague-Dawley rats were orally gavaged with 105Cryp-tosporidium oocysts to establish the model of post-infec-tion irritable bowel syndrome (PI-IBS). Rats then re-ceived 50 μg·kg-1·d-1of octreotide by intraperito-neal injection from day 10 to day 17 post-infection. Animals were sacrificed on day 17,37 and 50 post-in-fection for immunohistochemical analysis and on day 14,35 and 50 for mRNA expression analysis of SSTR4 and SSTR5 subtypes. Results Immunohistological a-nalysis of jejunum tissues demonstrated that SSTR5 was mainly expressed in submucosa while a little in crypt,while SSTR4 was mainly expressed in crypt while a lit-tle in submucosa and absorptive cells. Real-time PCR analysis indicated a significant increase of SSTR4 and SSTR5 expression in the inflamed jejunum. Octreotide treatment decreased the expression of SSTR4 and SSTR5 on day 50 post-infection. Conclusions SSTR4 and SSTR5 may be involved in the inflammatory reac-tion in PI-IBS rats induced by Cryptosporidium parvu-man, which shows an increase in SSTR4 and SSTR5 mRNA expression in jejunum. Octreotide therapy in-hibits the jejunum hypersensitivity and relieve PI-IBS symptoms, which may be related to the decrease of SSTR4 and SSTR5 expression.
