Abstract Background According to traditional Chinese medicine (TCM), drugs supplementing the vital energy, Qi, can eliminate tumors by restoring host immunity. The objective of this study is to investigate the underlying immune mechanisms of anti‐tumor activity associated with Qi‐supplementing herbs, specifically the paired use of Huangqi and Danggui. Methods Analysis of compatibility regularity was conducted to screen the combination of Qi‐supplementing TCMs. Using the MTT assay and a transplanted tumor mice model, the anti‐tumor effects of combination TCMs were investigated in vitro and in vivo. High content analysis and flow cytometry were then used to evaluate cellular immunity, followed by network pharmacology and molecular docking to dissect the significant active compounds and potential mechanisms. Finally, the anti‐tumor activity and the mechanism of the active ingredients were verified by molecular experiments. Results There is an optimal combination of Huangqi and Danggui that, administered as an aqueous extract, can activate immunity to suppress tumor and is more effective than each drug on its own in vitro and in vivo. Based on network pharmacology analysis, PIK3R1 is the core target for the anti‐tumor immunity activity of combined Huangqi and Danggui. Molecular docking analysis shows 6 components of the combined Danggui and Huangqi extract (quercetin, jaranol, isorhamnetin, kaempferol, calycosin, and suchilactone) that bind to PIK3R1. Jaranol is the most important component against breast cancer. The suchilactone/jaranol combination and, especially, the suchilactone/kaempferol combination are key for immunity enhancement and the anti‐tumor effects of the extract. Conclusions The combination of Huangqi and Danggui can activate immunity to suppress breast cancer and is more effective than the individual drugs alone.

Ischemic heart disease refers to the imbalance between the supply and demand of myocardial blood; it has various causes and results in a class of clinical diseases characterized by myocardial ischemia (MI). In recent years, the incidence of cardiovascular disease has become higher and higher, and the number of patients with ischemic heart disease has also increased year by year. Traditional treatment methods include drug therapy and surgical treatment, both of which have limitations. The former maybe develop risks of drug resistance and has more significant side effects, while the latter may damage blood vessels and risk infection. At this stage, a new cell-free treatment method needs to be explored. Many research results have shown that exosomes from different cell sources can protect the ischemic myocardium via intercellular action methods, such as promoting angiogenesis, inhibiting myocardial fibrosis, apoptosis and pyroptosis, and providing a new basis for the treatment of MI. In this review, we briefly introduce the formation and consequences of myocardial ischemia and the biology of exosomes, and then focus on the role and mechanism of exosomes from different sources in MI. We also discuss the role and mechanism of exosomes pretreated with Chinese and Western medicines on myocardial ischemia. We also discuss the potential of exosomes as diagnostic markers and therapeutic drug for MI.

Objective: Currently, coronavirus disease 2019 (COVID-19) has spread worldwide and become a global health concern. Here, we report a familial cluster of six patients infected with severe acute respiratory coronavirus 2 (SARS-CoV-2) in a northern Chinese region and share our local experience with regard the control of COVID-19. Methods: The demographic data, clinical features, laboratory examinations, and epidemiological characteristics of enrolled cases were collected and analyzed. Two family members (Cases 1 and 2) had Hubei exposure history and were admitted to the hospital with a confirmed diagnosis of COVID-19; eight familial members who had contact with them during the incubation period underwent quarantine in a hospital.We closely followed up all the family members and analyzed their clinical outcome. Results: Case 3 had negative SARS-CoV-2 reverse transcription-polymerase chain reaction (RT-PCR) results but was suspected to have COVID-19 because of radiographic abnormalities. Cases 4 and 5 developed symptomatic COVID-19. Case 6 was considered an asymptomatic carrier as his SARS-CoV-2 RT-PCR result was positive. The other four family members with close contacts to COVID-19 patients had no evidence of SARS-CoV-2 infection. Conclusions: Our findings suggest that COVID-19 has infectivity during the incubation period and preventive quarantine is effective for controlling an outbreak of COVID-19 infection.

In inter-satellite laser communication, four-quadrant detector is often used in precise tracking unit for spot location. The positioning error directly affects the angular measurement accuracy of fine tracking unit. In order to achieve the tracking precision of micro-radian magnitude, this paper studies various noise factors that affect the positioning accuracy of the detector, simplifying the analysis according to the practice of inter-satellite laser communication, and putting forward the specific calculation method of positioning error. Finally, we evaluate the influence degree of each factor through a specific example. The results show that the signal-to-noise ratio of the received signal increases with the increasing of emitting power in a certain range with reduced positioning error. However, positioning error does not decrease linearly with the increase of transmitting power. When the transmitting power increases to a certain extent, the reduction of tracking error is limited. At this time, it will be very expensive to improve the tracking precision simply by increasing the transmitting power.

Objectives: Older antimicrobials such as fosfomycin are being considered as alternative agents in the treatment of drug-resistant organisms. However, there are limited data on the usefulness of fosfomycin against carbapenem-resistant Klebsiella pneumoniae (CRKP). This study aimed to investigate the prevalence of fosfomycin resistance and associated mechanisms in CRKP. Methods: A total of 99 clinical CRKP isolates were collected in the Second Affiliated Hospital of Wenzhou Medical University (Wenzhou, China) between January 2017 and June 2018. Fosfomycin susceptibility testing was performed by the agar dilution method. Carbapenemase and fosfomycin resistance genes were detected by PCR. Analysis of the murA, glpT, uhpT, uhpA, ptsI and cyaA genes was performed by PCR and sequencing of four fosfomycin-resistant fosA3-negative CRKP strains. Conjugation experiments were employed to determine the mobility of the fosA3 gene. Results: Of the 99 CRKP isolates, fosfomycin-non-susceptibility was detected in 48 (48.5%) isolates, among which the fosA3 gene was detected in 44. Among the four fosfomycin-resistant fosA3-negative CRKP isolates, one isolate possessed a single nucleotide insertion and deletion mutations as well as 219 nucleotide substitution mutations in murA, two isolates possessed deletion or mutation of large DNA fragments in glpT, and one isolate possessed a fragment insertion sequence in glpT. Transfection into Escherichia coli J53 via plasmid conjugation was successful for 19 (43.2%) of the 44 fosA3-positive CRKP isolates. Conclusion: The fosA3 gene is the primary mechanism of fosfomycin resistance in CRKP and can be transmitted widely by plasmid in hospitals. Mutations in murA and glpT were found in fosfomycin-resistant fosA3-negative CRKP.

Functionalization and bestowing high values upon bioactive tea polysaccharides have been focused recently. For this purpose, the immune activation effect on RAW264.7 macrophages promoted by Lu’an Guapian polysaccharide (LGP-1, 2.35 × 105 Da) was investigated firstly. LGP-1 was obtained and characterized via DEAE 52 ion exchange column, high performance liquid chromatography and atomic force microscope. Immunological assay manifested a remarkable promotion effect on macrophages. LGP-1 could significantly stimulate the phagocytosis of macrophages, promote NO generation and trigger TNF-α, IL-6, IL-1β release dose-dependently. Fluorescence labeling tests confirmed the production level of reactive oxygen species increased obviously. Western blot results demonstrated that the treated macrophages were able to increase PI3K expression and p65 nuclear translocation, indicated that LGP-1 enhanced macrophage immunity via PI3K/AKT and NF-κB signaling pathways. Moreover, TLR4 was involved in the process. These results made clear that LGP-1 could be explored as a bioactive substance applied in functional foods.

Objective To analyze the correlation between the Kellgren–Lawrence (K‐L) score of knee osteoarthritis (KOA) patients with different degrees and their urine concentration of C‐terminal telopeptide of collagen type II (CTX‐II) and interleukin‐1β (IL‐1β), and to further evaluate the diagnostic value of CTX‐II and IL‐1β during the pathological process by producing an experimental osteoarthritis (OA) model in rabbits. Methods From 1 January 2017 to 31 December 2018, a total of 34 subjects (7 mild, 9 moderate, 9 severe arthritis patients, and 9 healthy individuals) comprising 16 men and 18 women were included in this study. Patients were diagnosed according to the American College of Rheumatology (ACR) criteria. The urine of all subjects was collected to detect the concentration of CTX‐II and IL‐1β. The rabbits in the KOA group were subjected to protease (control group with saline) injection into the articular cavity of their right knees and immobilization with gypsum. We used radiological and histological examination to identify the KOA model. ELISA was applied to investigate the concentrations of CTX‐II and IL‐1β in urine and serum, and Spearman's rank correlation analysis was used to analyze the correlation. Results There was no significant difference in the mean ages and body mass index (BMI) between groups. The mean ages of mild, moderate, and severe arthritis patients and healthy individuals were 54.29 ± 5.76, 58.44 ± 6.44, 59.89 ± 6.75, and 56.67 ± 4.18 years, respectively. The mean BMI of mild, moderate, and severe arthritis patients and healthy individuals were 23.59 ± 1.56, 23.57 ± 2.06, 24.46 ± 1.64, and 23.42 ± 1.35 kg/m2, respectively. The Kellgren–Lawrence (K‐L) score was higher with the aggravation of KOA. The K‐L scores of mild, moderate, and severe KOA patients were 1.14 ± 0.38, 2.56 ± 0.53, and 3.63 ± 0.52, respectively. The KOA symptoms of patients became more severe, with not only increased K‐L scores but also elevated concentrations of CTX‐II and IL‐1β. Moreover, there was a positive correlation between CTX‐II and IL‐1β of all subjects (r = 0.974, P

Mild intrauterine hypoperfusion (MIUH) is a serious pathological event that affects the growth and development of fetuses and offspring. MIUH can lead to growth restriction, low birth weight, neurodevelopmental disorders, and other adverse clinical outcomes. To study the effects of MIUH on learning and memory function in offspring, a model of MIUH was established by placing a coil (length 2.5 mm, diameter 0.24 mm) on the uterine artery and ovarian uterine artery of Sprague-Dawley rats in the second trimester of pregnancy (day 17). Next, 120 mg/kg lithium chloride (the MIUH + Li group) or normal saline (the MIUH group) was injected intraperitoneally into these rats. In addition, 120 mg/kg lithium chloride (the Li group) or normal saline (the SHAM group) was injected intraperitoneally into pregnant rats without coil placement. The Morris water maze was used to detect changes in learning and memory ability in the offspring at 4 weeks after birth. In the MIUH group, the escape latency and journey length before reaching the platform were both increased, and the number of times that the platform was crossed and the activity time in the target quadrant within 90 seconds were both decreased compared with the SHAM group. Immunofluorescence double staining and western blot assays demonstrated that hippocampal nestin and Ki67 (both cell-proliferation-related proteins) expression was significantly downregulated in the MIUH group compared with the SHAM group. Furthermore, western blot assays were conducted to investigate changes in related signaling pathway proteins in the brains of offspring rats, and revealed that glycogen synthase kinase 3β (GSK3β) expression was upregulated and β-catenin expression was downregulated in the MIUH group compared with the SHAM group. In addition, compared with the MIUH group, the expression levels of p-GSK3β and β-catenin were upregulated in the MIUH + Li group. These results suggest that MIUH may affect learning and memory function in rat offspring by regulating the GSK3β signaling pathway. The experimental procedures were approved by Animal Ethics Committee of Shengjing Hospital of China Medical University (approval No. 2018PS07K) in June 2018.

AIM: To investigate the relationship between neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR)and type 2 diabetic retinopathy(DR).METHODS:A total of 200 cases with type 2 diabetes mellitus were involved. All patients were divided into three groups according to the fundus examination: diabetes mellitus(DM, n=100), non-proliferative diabetic retinopathy(NPDR, n=62)and proliferative diabetic retinopathy(PDR, n=38). 100 healthy persons were selected as the normal control group(NCG, n=100). The related indicators, such as neutrophil count, lymphocyte count and platelet count were measured. RESULTS: The value of NLR was significantly higher in PDR group patients than in NC group(1.81), DM group(1.76)and NPDR group(1.85)(PPPCONCLUSION: The value of NLR and PLR increased in the PDR group, but it is not independent risk factor for diabetic retinopathy.

Multiple congenital anomalies-hypotonia-seizures syndrome 1 (MCAHS1) caused by phosphatidylinositol-glycan biosynthesis class N (PIGN) mutations is an autosomal recessive disease involving many systems of the body, such as the urogenital, cardiovascular, gastrointestinal, and central nervous systems. Here, compound heterozygous variants NM_012327.6:c.2427-2A > G and c.963G > A in PIGN were identified in a Chinese proband with MCAHS1. The features of the MCAHS1 family proband were evaluated to understand the mechanism of the PIGN mutation leading to the occurrence of MCAHS1. Ultrasound was conducted to examine the fetus, and his clinical manifestations were evaluated. Genetic testing was performed by whole-exome sequencing and the results were verified by Sanger sequencing of the proband and his parents. Reverse transcription-polymerase chain reaction was performed, and the products were subjected to Sanger sequencing. Quantitative PCR (Q-PCR) was conducted to compare gene expression between the patient and wild-type subjects. The compound heterozygous mutation NM_012327.6:c.2427-2A > G and c.963G > A was identified by whole-exome sequencing and was confirmed by Sanger sequencing. The NM_012327.6:c.2427-2A > G mutation led to skipping of exon 26, which resulted in a low expression level of the gene, as measured by Q-PCR. These findings provided a basis for genetic counseling and reproduction guidance in this family. Phenotype-genotype correlations may be defined by an expanded array of mutations.

Autosomal dominant non-syndromic hearing loss (ADNSHL) has a broad phenotypic spectrum which includes bilateral, symmetrical, and high-frequency sensorineural hearing loss, that eventually progresses into hearing loss at all frequencies. Several genetic variations have been identified as causal factors underlying deafness, autosomal dominant 5 (DFNA5) gene-related hearing loss. Here, we report a novel mutation (c.991-1G > C) in DFNA5, which co-segregated with late-onset ADNSHL in a Chinese family and was identified via exome sequencing and Sanger sequencing of DNA from peripheral blood of the family members. Further sequencing of cDNA derived from peripheral blood mRNA revealed that the c.991-1G >C mutation led to the skipping of exon 8, which is a known pathogenic mechanism for DFNA5-related hearing loss.

Abstract Background In 2005, the FDA cautioned that exposure to paroxetine, a selective serotonin reuptake inhibitor (SSRI), during the first trimester of pregnancy may increase the risk of cardiac malformations. Since then, the association between maternal use of SSRIs during pregnancy and congenital malformations in infants has been the subject of much discussion and controversy. The aim of this study is to systematically review the associations between SSRIs use during early pregnancy and the risk of congenital malformations, with particular attention to the potential confounding by indication. Methods The study protocol was registered with PROSPERO (CRD42018088358). Cohort studies on congenital malformations in infants born to mothers with first-trimester exposure to SSRIs were identified via PubMed, Embase, Web of Science, and the Cochrane Library databases through 17 January 2018. Random-effects models were used to calculate summary relative risks (RRs). Results Twenty-nine cohort studies including 9,085,954 births were identified. Overall, use of SSRIs was associated with an increased risk of overall major congenital anomalies (MCAs, RR 1.11, 95% CI 1.03 to 1.19) and congenital heart defects (CHD, RR 1.24, 95% CI 1.11 to 1.37). No significantly increased risk was observed when restricted to women with a psychiatric diagnosis (MCAs, RR 1.04, 95% CI 0.95 to 1.13; CHD, RR 1.06, 95% CI 0.90 to 1.26). Similar significant associations were observed using maternal citalopram exposure (MCAs, RR 1.20, 95% CI 1.09 to 1.31; CHD, RR 1.24, 95% CI 1.02 to 1.51), fluoxetine (MCAs, RR 1.17, 95% CI 1.07 to 1.28; CHD, 1.30, 95% CI 1.12 to 1.53), and paroxetine (MCAs, RR 1.18, 95% CI 1.05 to 1.32; CHD, RR 1.17, 95% CI 0.97 to 1.41) and analyses restricted to using women with a psychiatric diagnosis were not statistically significant. Sertraline was associated with septal defects (RR 2.69, 95% CI 1.76 to 4.10), atrial septal defects (RR 2.07, 95% CI 1.26 to 3.39), and respiratory system defects (RR 2.65, 95% CI 1.32 to 5.32). Conclusions The evidence suggests a generally small risk of congenital malformations and argues against a substantial teratogenic effect of SSRIs. Caution is advisable in making decisions about whether to continue or stop treatment with SSRIs during pregnancy.

Unintended pregnancy is a global issue, with approximately 85,000,000 women around the world having unintended pregnancy annually. The contents of clinical application of women's contraceptive methods are very wide, involving multiple areas. This consensus deeply discusses the specific contraceptive needs at different statuses, combined with gynecological diseases, postabortion contraception, and postpartum family planning, ensuring the correct use of contraceptive methods under the corresponding status. The top priority of the consensus is the specific contraception consensus section for women combined with gynecological diseases because medical treatment effect as well as side effects should be weighed carefully. The consensus is to make high-efficiency and individual contraceptive strategy for different groups based on multidisciplinary (gynecology, obstetrics, and family planning) and multidimensional aspects, which can provide uniform guidance for medical and health organizations under the condition as relevant global guidance or consensus is still lacking.

AIM: To investigate the efficacy and safety of low dose mitomycin C(MMC)to prevent haze in trans photorefractive keratectomy(TransPRK)with moderate and high myopia, and to observe the changes of corneal density.METHODS: Sixty-one patients underwent TransPRK with moderate and high myopia. Eyes were divided into research group(0.1g/L MMC for 40s)and control group(0.2g/L MMC for 40s)randomly. There were 21 patients in research group and 40 patients in control group. Cornea epithelial healing time, pain score, visual acuity, manifest refraction, haze and cornea density were analyzed.RESULTS: The epithelial healing time(0.1g/L group: 3.86±1.11d, 0.2g/L group: 4.23±1.27d)and pain score(0.1g/L group: 2.01±0.58, 0.2g/L group: 1.79±0.7)were no significant difference between two groups(P=0.667, P=0.582). It was similar in spherical equivalent at 1mo and 3mo post-operation(0.1g/L group: 0.28±0.25, 0.05±0.23D; 0.2g/L group: -0.13±0.17, 0.07±0.22D; P=0.178, P=0.490). The BCVA of control group decreased at 1mo and improved to the same level as pre-operation at 3mo(F=15.847, PF=3.038, P=0.093). There were also no significant difference in Haze between two groups post-operation(z=-0.709, P=0.479; z=-0.478, P=0.633).The change of cornea density was matched with the BCVA(0.1g/L group F=27.399, P=0.001; 0.2g/L group F=8.313, P=0.001)and it was similar between two groups. CONCLUSION: The using of low dose MMC to prevent haze in TransPRK with moderate and high myopia is safe and effective. It is therapeutic equivalence to regular dose(0.2g/L). Besides the slit lamp, we can use the corneal density to measure the corneal transparency.

Silver–Russell syndrome (SRS) is a rare, well-recognized disorder characterized by growth restriction, including intrauterine and postnatal growth. Most SRS cases are caused by hypomethylation of the paternal imprinting center 1 (IC1) in chromosome 11p15.5 and maternal uniparental disomy in chromosome 7 (UPD7). Here, we report on a Chinese family with a 4 year old male proband presenting with low birth weight, growth retardation, short stature, a narrow chin, delayed bone age, and speech delays, as a result of a rare molecular etiology. Whole-exome sequencing was conducted, and a novel de novo IGF2 splicing variant, NM_000612.4: c.157+5G > A, was identified on the paternal allele. In vitro functional analysis by RT-PCR and Sanger sequencing revealed that the variant leads to an aberrant RNA transcript lacking exon 2. Our results further confirm the IGF2 variant mediates SRS and expand the pathogenic variant and phenotypic spectrum of IGF2-mediated SRS. The results indicate that, beyond DNA methylation and UPD7 and CDKN1C variant tests, IGF2 gene screening should also be considered for SRS molecular diagnoses.

For supporting efficient host mobility and mapping identifiers onto locators,a distributed dynamic mobility mapping scheme based on cost function was proposed.In the scheme,depending on the mobility pattern and communication feature,the communication of mobile node is divided into three communication models,namely,moving update model,balanced transmission model and resolving query model.In order to minimize the total resolving cost,three mapping approach are proposed based on distributed multicast,consistent hash functions and proactive sharing respectively in the mobile domain.For each mapping approach,corresponding registration update,resolution query and packet delivery strategies are designed.Simulation results show that the scheme can achieve the minimum resolving cost,and can have low resolve latency and good adaptability for network topology dynamic changing.

Previous studies investigating the relationship between passive maternal smoking and preterm birth reveal inconsistent results. We conducted the current meta-analysis of observational studies to evaluate the relationship between passive maternal smoking and preterm birth. We identified relevant studies by searching PubMed, EMBASE, and ISI Web of Science databases. We used random-effects models to estimate summary odds ratios (SORs) and 95% confidence intervals (CIs) for aforementioned association. For the analysis, we included 24 studies that involved a total of 5607 women who experienced preterm birth. Overall, the SORs of preterm birth for women who were ever exposed to passive smoking versus women who had never been exposed to passive smoking at any place and at home were 1.20 (95%CI = 1.07-1.34,I(2) = 36.1%) and 1.16 (95%CI = 1.04-1.30,I(2) = 4.4%), respectively. When we conducted a stratified analysis according to study design, the risk estimate was slightly weaker in cohort studies (SOR = 1.10, 95%CI = 1.00-1.21,n = 16) than in cross-sectional studies (SOR = 1.47, 95%CI = 1.23-1.74,n = 5). Additionally, the associations between passive maternal smoking and preterm birth were statistically significant for studies conducted in Asia (SOR = 1.26, 95%CI = 1.05-1.52), for studies including more than 100 cases of preterm birth (SOR = 1.22, 95%CI = 1.05-1.41), and for studies adjusted for maternal age (SOR = 1.27,95%CI = 1.09-1.47), socioeconomic status and/or education (SOR = 1.28, 95%CI = 1.10-1.49), body mass index (SOR = 1.33, 95%CI = 1.04-1.71), and parity (SOR = 1.27, 95%CI = 1.13-1.43). Our findings demonstrate that passive maternal smoking is associated with an increased risk of preterm birth. Future prospective cohort studies are warranted to provide more detailed results stratified by passive maternal smoking during different trimesters of pregnancy and by different types and causes of preterm birth.

BACKGROUND: Association between parity and colorectal cancer (CRC) risk has been investigated by several epidemiological studies but results are controversial, yet a comprehensive and quantitative assessment of this association has not been reported so far. METHODS: Relevant published studies of parity and CRC were identified using MEDLINE, EMBASE and Web of Science databases through end of April 2013. Two authors independently assessed eligibility and extracted data. Eleven prospective studies reported relative risk (RR) estimates and 95% confidence intervals (CIs) of CRC risk associated with parity. We pooled the RR from individual studies using fixed- or random-effects models and carried out heterogeneity and publication bias analyses. RESULTS: The summary RR for the ever parity vs. nulliparous was 0.95 (95% CI: 0.88-1.02), with no heterogeneity (Q = 9.04, P = 0.443, I (2) = 0.5%). Likewise, no significant association was yielded for the highest vs. lowest parity number (RR = 1.02, 95% CI: 0.89-1.17), with moderate heterogeneity (Q = 17.48, P = 0.094, I (2) = 37.1%). Dose-response analysis still indicated no effect of parity on CRC risk and the summary RR of per one livebirth was 0.99 (95% CI: 0.96-1.02), with moderate of heterogeneity (Q = 16.50, P

Adhesion molecules play important roles in airway hyperresponsiveness or airway inflammation. Our previous study indicated catenin alpha-like 1 (CTNNAL1), an alpha-catenin-related protein, was downregulated in asthma patients and animal model. In this study, we observed that the expression of CTNNAL1 was increased in lung tissue of the ozone-stressed Balb/c mice model and in acute ozone stressed human bronchial epithelial cells (HBEC). In order to identify the possible DNA-binding proteins regulating the transcription of CTNNAL1 gene in HBEC, we designed 8 oligo- nucleotide probes corresponding to various regions of the CTNNAL1 promoter in electrophoretic mobility shift assays (EMSA). We detected 5 putative transcription factors binding sites within CTNNAL1 promoter region that can recruit LEF-1, AP-2α and CREB respectively by EMSA and antibody supershift assay. Chromatin immunoprecipitation (ChIP) assay verified that AP-2 α and LEF-1 could be recruited to the CTNNAL1 promoter. Therefore we further analyzed the functions of putative AP-2 and LEF-1 sites within CTNNAL1 promoter by site-directed mutagenesis of those sites within pGL3/FR/luc. We observed a reduction in human CTNNAL1 promoter activity of mutants of both AP-2α and LEF-1 sites. Pre-treatment with ASOs targeting LEF-1and AP-2α yielded significant reduction of ozone-stress-induced CTNNAL1 expression. The activation of AP-2α and LEF-1, followed by CTNNAL1 expression, showed a correlation during a 16-hour time course. Our data suggest that a robust transcriptional CTNNAL1 up-regulation occurs during acute ozone-induced stress and is mediated at least in part by ozone-induced recruitments of LEF-1 and AP-2α to the human CTNNAL1 promoter.

Background: This study explores the development status, research hotspots, and frontiers of lung cancer home management through visual analysis of lung cancer home management literature, providing reference for subsequent research. Methods: The relevant literatures about home management of lung cancer included in Web of Science from 2000 to 2022 were searched by computer. CiteSpace (6.1.R3) was used to draw the research country, co-cited articles, keyword co-occurrence and time axis of co-cited clustering map of lung cancer home management literature. Results: 171 articles were included. The countries with more documents are the United States, China and Japan. The cooperation between countries is centered on the United States. The intermediary role of the United States is obvious. The co-cited articles show that the reliability and validity of the scale, aerobic exercise training and natural radon gas have an important impact on the research of home management of lung cancer. The research keywords focus on lung cancer, exercise, quality of life, etc. Conclusion: There are few researches on home management of lung cancer. In the future research, more attention should be paid to the research related to home management of lung cancer. Nurse managers need to be more aware of the new era of directing nursing care into home care. So as to improve the quality of life of lung cancer patients at home and promote their rehabilitation.
