Objective To compare the results of accumulation and continuation methods in indoor radon measurement. Methods The radon concentrations in 30 households in 7 provincial capital cities of China were simultaneously measured using both accumulation and continuation methods. Results The radon concentration measured by accumulation method in 30 households ranged from 21 to 323 Bq/m³, with a median M(P₂₅, P₇₅) of 70.5 (43.8, 111). The radon concentration measured by the continuation method ranged from 16.1 to 258 Bq/m³, with a median M(P₂₅, P₇₅) of 100 (51.3, 141). The average relative percent deviation between the two measurement methods was 41.8%. There were significant differences among the measurement results at 8, 16, and 24 h by the continuation method. Pairwise comparisons showed there were statistical diffferences between 8 h and 16 h, as well as between 8 h and 24h; however, no statistical significance was found (P < 0.05), between 16 h and 24 h. Conclusion The overall continuous measurement results of the 30 households were higher than those of cumulation method. The comparison between accumulation and continuation measurement results did not show a high level of correlation (r=0.49). The continuation method is significantly affected by environmental factors, and the length of the measurement period can affect the measurement results. The selection of indoor radon measurement methods should consider the purpose, sample size, and environmental conditions.

Objective To explore the mechanism of modified Xiangsha Liujunzi Decoction in regulating apolipoproteinA-Ⅰ (apoA-Ⅰ),improving endoplasmic reticulum stress,regulating glucose and lipid metabolism,and preventing and treating dyslipidemia in mice. Methods Wild-type (WT) C57BL/6J mice were randomly divided into the WT,WT+high-fat diet(HFD),and WT+HFD+Xiangsha Liujunzi Decoction(XSLJZ) groups according to the random number table method. ApoA-Ⅰ-/-mice were randomly divided into the apoA-Ⅰ-/-,apoA-Ⅰ-/-+HFD,and apoA-Ⅰ-/-+HFD+XSLJZ groups (n=10) according to the random number table method. D12492 was used for HFD feeding to establish a hyperlipidemic mouse model. Modified XSLJZ (23.66g/kg) was administered daily by gavage from the ninth week. Serum and liver tissue were collected for testing after 4 weeks. An automatic biochemical analyzer was used to detect blood lipid levels;an enzyme-linked immunosorbent assay was used to detect serum fasting blood glucose (FBG) and insulin (INS) levels,and the INS resistance index (HOMA-IR) was calculated. Hematoxylin and eosin staining was used to observe the pathological changes in the liver. Oil red O staining was used to observe the lipid deposition in the liver. TG levels in liver tissue were detected using the microplate method. Real-time PCR was used to detect apoA-Ⅰ,glucose-regulated proteins (GRP78),sterol regulatory element binding protein-1c (SREBP-1c),acetyl CoA carboxylase 1 (ACC1),and fatty acid synthase (FASN) mRNA expression levels in liver tissue. The WES fully automated protein expression analysis system was used to detect apoA-Ⅰ,GRP78,inositol-requiring enzyme 1 (IRE1),p-IRE1,c-Jun N-terminal kinase (JNK),p-JNK,insulin receptor substrate (IRS1),p-IRS1,protein kinase B (Akt),p-Akt,SREBP-1c,ACC1,and FASN protein expression levels in liver tissue. Results Compared to the WT group,the WT+HFD group showed a significant increase in serum lipids,FBG,INS levels,and the HOMA-IR index (P<0.05). The orange-red lipid droplets in liver tissue increased,fat vacuoles were apparent,and TG levels were significantly increased. ApoA-Ⅰ mRNA and protein expression levels were significantly reduced,whereas GRP78,SREBP-1c,ACC1,and FASN mRNA expression levels were increased,GRP78,SREBP-1c,ACC1,and FASN protein levels and the IRE1,JNK,IRS1,and Akt phosphorylation degree were increased (P<0.05). The serum TG,HDL-C,LDL-C,FBG,and INS levels and the HOMA-IR index in the WT+HFD group were significantly reduced after administering modified XSLJZ (P<0.05). The orange-red lipid droplets in liver tissue were significantly reduced,fat vacuolization was alleviated,and TG levels were significantly reduced,ApoA-Ⅰ mRNA and protein expression levels were significantly increased,whereas GRP78,SREBP-1c,ACC1,and FASN mRNA expression levels were reduced,GRP78,SREBP-1c,ACC1,and FASN protein expression levels and the IRE1,JNK,IRS1,and Akt phosphorylation degree were reduced (P<0.05). Compared to the WT+HFD group,the TG,LDL-C,and FBG levels and HOMA-IR index in the serum of the apoA-Ⅰ-/-+HFD group were significantly increased,whereas the HDL-C levels were significantly decreased (P<0.05). Diffuse orange-red lipid droplets in liver tissue and a significant increase in fat vacuoles were observed. Furthermore,TG levels were significantly increased,SREBP-1c,ACC1,FASN mRNA,SREBP-1c,and ACC1 protein expression levels and IRE1,JNK,IRS1,and Akt phosphorylation levels were significantly increased (P<0.05). Compared to the WT+HFD+XSLJZ group,the apoA-Ⅰ-/-+HFD+XSLJZ group showed a significant increase in serum TG,LDL-C,FBG,and INS levels,and the HOMA-IR index,whereas HDL-C levels decreased significantly (P<0.05). The deposition of orange-red lipid droplets in liver tissue improved,and TG levels significantly decreased,GRP78,SREBP-1c,ACC1,and FASN mRNA expression levels,GRP78,SREBP-1c,and ACC1 protein levels,and IRE1,JNK,IRS1,and Akt phosphorylation levels increased (P<0.05). Conclusion Modified XSLJZ improves liver glucose and lipid metabolism disorder by regulating apoA-Ⅰ to alleviate endoplasmic reticulum stress.

Based on literature research and Delphi method, the curative effect evaluation criteria of Traditional Chinese Medicine (TCM) edema were revised, in order to promote the standardization construction of the curative effect evaluation of edema and strengthen the research on the revision technology of TCM standards. From January 1, 1994 to July 1, 2021, the China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (Chongqing VIP), Chinese Academic Periodical Database (Wanfang Data) and Chinese Biomedical Literature Service System (SinoMed) were searched, and 221 articles were included. Then the questionnaire item pool was constructed after extracting the contents of the articles. Delphi method was used to conduct two rounds of expert questionnaire survey. And then the concentration degree and coordination degree of expert opinions were counted and analyzed to screen out the content to be revised and the indicators to be included in the revised version, so as to form the revised version of curative effect evaluation criteria of edema. A total of 32 experts participated in this study, and the positive coefficient of experts in the first round was 84.21%, and the positive coefficient of experts in the second round was 78.13%. The mean value ( Xˉ), full score ratio, rank sum, coefficient of variation ( CV), Kendall's coefficient of concordace (Kendall's W) were used to select the questionnaire items. Kendall's W of the second round of expert questionnaire survey was 0.368, P=0.000, higher than that of the first round, and 11 items were finally included in the curative effect evaluation. The CV of the included items in the second round of the questionnaire is lower than that in the first round, and Kendall's W was higher than that in the first round, and the expert opinions tend to be unified. Consensus was reached after the expert discussion meeting, and the revised version of curative effect evaluation criteria of edema has been preliminarily formed.

Objective:To understand the infection status and molecular types of rhinovirus (RV) among cases of Acute Respiratory Infections (ARIs) in Luohe City, Henan Province, from 2017 to 2022.Methods:From October 2017 to June 2022, clinical and epidemiological data were collected from 2 270 cases of ARIs at Luohe Central Hospital in Henan Province. Throat swab specimens were obtained from these cases. Real-time quantitative polymerase chain reaction (qPCR) was used to screen for RV-positive specimens. Subsequently, the positive samples were subjected to nested reverse transcription polymerase chain reaction (nested RT-PCR) to amplify the full-length VP1 region. Using the MEGA software, along with 169 RV reference strains recommended by the International Committee on Taxonomy of Viruses, a phylogenetic tree was constructed to determine RV types.Results:Among the 2 270 cases of ARIs, there were 1 283 male cases (56.52%). The median age ( Q 1, Q 3) was 3 (1, 6) years, with the population under 5 years old accounting for 68.59% (1 557/2 270). RV was detected in 137 cases (6.04%), of which 68 cases (49.64%) showed co-detection with other viruses, with the most common being co-detection with enterovirus, accounting for 14.60% (20/137). The RV detection rates in the age groups of 0-4 years, 5-14 years, 15-59 years, and≥60 years were 6.42% (100/1 557), 4.69% (21/448), 3.80% (6/158), and 9.35% (10/107), respectively, with no statistically significant differences ( χ2=5.310, P=0.150). The overall detection rates of RV before (2017-2019) and during (2020-2022) the COVID-19 pandemic showed no statistically significant difference ( χ2=1.823, P=0.177). A total of 109 VP1 sequences were obtained, including 62 types. Among them, RV-A, RV-B, and RV-C had 42, 3, and 17 types respectively. Conclusion:RV is one of the predominant pathogens in ARIs cases in Luohe City, Henan Province, from 2017 to 2022. Multiple types of RV co-circulate without any apparent dominant type.

Objective:To explore the clinical value of synovial fluid calprotectin for the diagnosis of periprosthetic joint infection (PJI).Methods:Based on prospective cohort study design, a total of 82 patients suspected of PJI after hip and knee arthroplasty in the First Medical Center of the PLA General Hospital from July 2021 to June 2022 were selected. Patients were divided into infection group (PJI, n=39) and non-infection group (non-PJI, n=43) according to the diagnostic criteria proposed by the Second International Consensus Conference in 2018. The matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was used for double-blind detection of calprotectin and internal reference standard (IRS) in synovial fluid of patients. The peaks of target protein and IRS were recorded for further analysis. Mann-Whitney U test was used to compare the concentrations of S100A8 and S100A9 between the two groups, and receiver operating characteristic curve (ROC) was used to analyze the diagnostic efficacy of S100A8 and S100A9 for PJI. Results:Calprotectin was detected as monomers S100A8 and S100A9. Synovial fluid S100A8 was significantly higher in the PJI group than that in the non-PJI group [1.57 (0.48, 4.17) vs 0.00 (0.00, 0.05), Z=?7.221, P<0.05]. Synovial fluid S100A9 was also significantly higher in the PJI group than that in the non-PJI group [0.74 (0.29, 1.70) vs 0.06 (0.00, 0.10), Z=?6.255, P<0.05]. When using S100A8 and S100A9 to diagnose PJI, the sensitivity were 97.4% and 87.2%, the specificity were 86.0% and 88.4%, and the area under the ROC were 0.964 (95% CI 0.929-0.998) and 0.902 (95% CI 0.924-0.996), respectively. Conclusion:The detection of synovial fluid S100A8 and S100A9 by MALDI-TOF MS can make a satisfactory diagnosis for PJI.

Objective:To investigate associations of cerebral perfusion impairment with early neurological deterioration (END) and poor outcome in patients with acute small subcortical infarction (SSI).Methods:Patients with SSI in the perforator artery region admitted to the Department of Neurology, Zhengzhou People's Hospital between January 2020 and November 2022 were prospectively included. END was defined as an increase of ≥2 in the total score of the National Institutes of Health Stroke Scale (NIHSS) or an increase of ≥1 in the motor function score within 72 h after admission. Poor outcome was defined as the modified Rankin Scale score of 2 at 90 d after onset. Cerebral perfusion impairment was defined according to MRI perfusion-weighted imaging parameters. The demographic, baseline clinical and imaging data were collected. Multivariate logistic regression analysis was used to determine associations of cerebral perfusion impairment and END and poor outcome in patients with SSI. Results:A total of 100 patients with SSI were enrolled, including 56 males (56.0%), and aged 69.2±5.8 years. Among them, 19 patients (19.0%) developed END, 27 (27.0%) had poor outcome, and 51 (51.0%) had significant cerebral perfusion impairment. There were statistically significant differences in high sensitivity C-reactive protein, white matter hyperintensities (WMHs) in the basal ganglia, enlarged perivascular space (EPVS) in the basal ganglia, deep cerebral microbleeds (CMBs), and cerebral perfusion impairment between the END group and the non-END group (all P<0.05). Multivariate logistic regression analysis showed that higher diastolic blood pressure (odds ratio [ OR] 1.070, 95% confidence interval [ CI] 1.003-1.141); P=0.040], deep WMHs ( OR 2.271, 95% CI 1.135-4.544; P=0.020), deep CMBs ( OR 5.047, 95% CI 1.240-20.549; P=0.024), and cerebral perfusion impairment ( OR 6.083, 95% CI 1.318-28.080; P=0.021) were independent risk factors for END in patients with SSI. There were statistically significant differences in hypersensitive C-reactive protein, NIHSS score at END, basal ganglia EPVS, END, and cerebral perfusion impairment between the poor outcome group and the good outcome group ( P<0.05). Multivariate logistic regression analysis showed that NIHSS score at END ( OR 1.485, 95% CI 1.034-2.133; P=0.032), basal ganglia EPVS ( OR 3.005, 95% CI 1.224-7.378; P=0.016), and cerebral perfusion impairment ( OR 9.234, 95% CI 1.994-42.765; P=0.004) were independent risk factors for the poor outcome at 90 d in patients with SSI, while anterior circulation infarction ( OR 0.066, 95% CI 0.013-0.334; P=0.001) was independently negatively correlated with the poor outcomes at 90 d after onset. Conclusion:Cerebral perfusion impairment is an independent risk factor for END and poor outcome at 90 d after onset in patients with SSI.

Abstract Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

Objective:To evaluate the relationship between hippocampal macrophage polarization and perioperative neurocognitive disorders in mice with tibial fractures.Methods:Forty-five clean-grade healthy male C57/BL6 mice, aged 5-7 months, were divided into 3 groups ( n=15 each) using the random number table method: control group (group C), anesthesia group (group A) and anesthesia surgery group (group AS). Group C received no treatment. Group A was anesthetized with isoflurane inhaled for 15 min. In AS group, intramedullary nail fixation of tibial fracture was performed under anesthesia through inhalation of 2% isoflurane. Morris water maze test and open field test were performed before anesthesia/on 1 day before surgery and after anesthesia/on 1, 3 and 7 days after operation. Five mice were randomly selected after the behavioral experiments were completed at each time point, and hippocampal tissues were taken after the animals were sacrificed for determination of the expression of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), IL-6, chemokine (c-c motif) ligand 12 (CCL2), CCL5, CCL8, iNOS and Arg-1 mRNA (by quantitative real-time polymerase chain reaction), expression of iNOS and Arg-1 proteins (by Western blot), and percentage of CD11b, CD45, CD86 and CD206 cells in hippcampal area (by immunofluorescence staining). Results:Compared with group C, the escape latency was significantly prolonged after operation, the number of crossing the platform was reduced after operation, the expression of TNF-ɑ, IL-6, CCL5 and CCL8 mRNA and iNOS protein and mRNA was up-regulated, the expression of Arg-1 protein and mRNA was down-regulated, the percentages of CD11b + CD45 + cells and CD11b + CD86 + cells in the hippocampus were increased, and the percentages of CD11b + CD206 + cells were decreased in AS group ( P<0.05), and no significant change was found in the parameters mentioned above in group A ( P>0.05). Compared with group A, the escape latency was significantly prolonged after surgery, the frequency of crossing the platform was reduced after surgery, the expression of iNOS mRNA was up-regulated, the percentages of CD11b + CD45 + cells and CD11b + CD86 + cells were increased, and the percentages of CD11b + CD206 + cells were decreased in AS group ( P<0.05). Conclusions:The occurrence of PND may be related to increased polarization to M1 macrophages in the hippocampus and decreased polarization to M2 macrophages in mice with tibial fracture, which further leads to central inflammatory responses.
