Objective To determine the prognostic biomarkers and new therapeutic targets of the lung adenocarcinoma (LUAD), based on which to establish a prediction model for the survival of LUAD patients. Methods An integrative analysis was conducted on gene expression and clinicopathologic data of LUAD, which were obtained from the UCSC database. Subsequently, various methods, including screening of differentially expressed genes (DEGs), Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis and Gene Set Enrichment Analysis (GSEA), were employed to analyze the data. Cox regression and least absolute shrinkage and selection operator (LASSO) regression were used to establish an assessment model. Based on this model, we constructed a nomogram to predict the probable survival of LUAD patients at different time points (1-year, 2-year, 3-year, 5-year, and 10-year). Finally, we evaluated the predictive ability of our model using Kaplan-Meier survival curves, receiver operating characteristic (ROC) curves, and time-dependent ROC curves. The validation group further verified the prognostic value of the model. Results The different-grade pathological subtypes' DEGs were mainly enriched in biological processes such as metabolism of xenobiotics by cytochrome P450, natural killer cell-mediated cytotoxicity, antigen processing and presentation, and regulation of enzyme activity, which were closely related to tumor development. Through Cox regression and LASSO regression, we constructed a reliable prediction model consisting of a five-gene panel (MELTF, MAGEA1, FGF19, DKK4, C14ORF105). The model demonstrated excellent specificity and sensitivity in ROC curves, with an area under the curve (AUC) of 0.675. The time-dependent ROC analysis revealed AUC values of 0.893, 0.713, and 0.632 for 1-year, 3-year, and 5-year survival, respectively. The advantage of the model was also verified in the validation group. Additionally, we developed a nomogram that accurately predicted survival, as demonstrated by calibration curves and C-index. Conclusion We have developed a prognostic prediction model for LUAD consisting of five genes. This novel approach offers clinical practitioners a personalized tool for making informed decisions regarding the prognosis of their patients.

Objective:To analyze the clinical characteristics of children with head and neck rhabdomyosarcoma (RMS) and to summarize the mid-long term efficacy of Beijing Children′s Hospital Rhabdomyosarcoma 2006 (BCH-RMS-2006) regimen and China Children′s Cancer Group Rhabdomyosarcoma 2016 (CCCG-RMS-2016) regimen.Methods:A retrospective cohort study. Clinical data of 137 children with newly diagnosed head and neck RMS at Beijing Children′s Hospital, Capital Medical University from March 2013 to December 2021 were collected. Clinical characteristic of patients at disease onset and the therapeutic effects of patients treated with the BCH-RMS-2006 and CCCG-RMS-2016 regimens were compared. The treatments and outcomes of patients with recurrence were also summarized. Survival analysis was performed by Kaplan-Meier method, and Log-Rank test was used for comparison of survival rates between groups.Results:Among 137 patients, there were 80 males (58.4%) and 57 females (41.6%), the age of disease onset was 59 (34, 97) months. The primary site in the orbital, non-orbital non-parameningeal, and parameningeal area were 10 (7.3%), 47 (34.3%), and 80 (58.4%), respectively. Of all patients, 32 cases (23.4%) were treated with the BCH-RMS-2006 regimen and 105 (76.6%) cases were treated with the CCCG-RMS-2016 regimen. The follow-up time for the whole patients was 46 (20, 72) months, and the 5-year progression free survival (PFS) and overall survival (OS) rates for the whole children were (60.4±4.4)% and (69.3±4.0)%, respectively. The 5-year OS rate was higher in the CCCG-RMS-2016 group than in BCH-RMS-2006 group ((73.0±4.5)% vs. (56.6±4.4)%, χ2=4.57, P=0.029). For the parameningeal group, the 5-year OS rate was higher in the CCCG-RMS-2016 group (61 cases) than in BCH-RMS-2006 group (19 cases) ((57.3±7.6)% vs. (32.7±11.8)%, χ2=4.64, P=0.031). For the group with meningeal invasion risk factors, the 5-year OS rate was higher in the CCCG-RMS-2016 group (54 cases) than in BCH-RMS-2006 group (15 cases) ((57.7±7.7)% vs. (30.0±12.3)%, χ2=4.76, P=0.029). Among the 10 cases of orbital RMS, there was no recurrence. In the non-orbital non-parameningeal RMS group (47 cases), there were 13 (27.6%) recurrences, after re-treatment, 7 cases survived. In the parameningeal RMS group (80 cases), there were 40 (50.0%) recurrences, with only 7 cases surviving after re-treatment. Conclusions:The overall prognosis for patients with orbital and non-orbital non-parameningeal RMS is good. However, children with parameningeal RMS have a high recurrence rate, and the effectiveness of re-treatment after recurrence is poor. Compared with the BCH-RMS-2006 regimen, the CCCG-RMS-2016 regimen can improve the treatment efficacy of RMS in the meningeal region.

OBJECTIVE To provide a reference for optimizing and promoting the quality standards of Shechuan naolitong granules. METHODS Fifteen batches of Shechuan naolitong granules were used as samples to establish HPLC fingerprints using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (2012 edition). Similarity evaluation and common peak identification were performed, and orthogonal partial least squares discriminant analysis (OPLS-DA) was used to assess quality differences among different batches and to screen quality differential components. Using salvianolic acid B(SAB) as the internal reference, quantitative analysis of multi-components by single-marker (QAMS) was developed to simultaneously determine geniposidic acid (GA), chlorogenic acid (CA), vaccarin (VA), ferulic acid (FA) and senkyunolide I (SI). The results were compared with those obtained by the external standard method. RESULTS A total of 13 common peaks were identified in the HPLC fingerprints of 15 batches of samples, and the similarities of the spectra were all above 0.96. Seven chromatographic peaks were identified as GA (peak 3), CA (peak 6), VA (peak 8), FA (peak 9), SI (peak 11), SAB(peak 12) and TA(peak 13). OPLS-DA indicated that the differential quality markers among 15 batches were peaks 5, 11 (SI), and 12 (SAB).Using SAB as the internal reference, the relative correction factors for GA, CA, VA, FA and SI were calculated as 1.058 4, 0.594 3, 0.643 3, 0.342 7 and 0.262 8, respectively. The mean content of GA, CA, VA, FA, SI and SAB across the 15 batches of samples were 0.155 0, 0.085 4, 0.140 3, 0.071 8, 0.072 7, 1.276 3 mg/g, respectively, showing no significant difference compared with the ESM (P>0.05). CONCLUSIONS The established HPLC fingerprint and QAMS are simple, efficient and economical, providing a reference for the quality control and further development of Shechuan naolitong granules.

Objective:To explore the impact of treatment duration with human urinary kallidinogenase (HUK) on the efficacy and safety of acute ischemic stroke (AIS).Methods:In this subgroup analysis of RESK study, a total of 990 AIS patients recruited from 65 centers in China between August 2015 and June 2020 were included and divided into short medication group (HUK for 8 days, n=185) or long medication group (HUK for 15 days or 21 days, n=805). The proportions of patients with modified Rankin Scale (mRS) score of 0, 0-1, 0-2 at 90 days, National Institutes of Health Stroke Scale (NIHSS) score change from baseline to 22 days, the proportions of patients with Barthel index (BI)≥95 at 90 days, and the incidences of adverse events were analyzed. Comparisons between groups were conducted using chi-square test, single factor and multivariate Logistic regression analysis, etc. Results:Multivariate regression analysis showed that the proportions of patients with 90-day mRS score of 0-2 [74.1% (137/185) vs 75.0% (604/805); OR=1.047, 95% CI 0.676-1.620, P=0.838] and 22-day NIHSS score change from baseline (4.60±2.00 vs 4.26±2.80; OR=-0.390, 95% CI -1.125-0.344, P=0.297) showed no statistically significant difference between the short medication and long medication groups; the proportions of patients with 90-day mRS score of 0-1 [48.1% (89/185) vs 59.1% (476/805); OR=0.674, 95%CI 0.463-0.983, P=0.041] and 90-day BI≥95 [43.6% (79/181) vs 55.1% (442/802); OR=0.614, 95%CI 0.420-0.897, P=0.012] were significantly lower in the short medication group than in the long medication group. There was no statistically significant difference in the incidences of adverse events between these 2 groups. Conclusions:In AIS patients, consecutive 8-day dosing of HUK improved immediate (22-day NIHSS score) and long-term outcome (90-day mRS score 0-2) and was safely tolerated. When applicable, extended duration of HUK could improve long-term disability-free rate (90-day mRS score 0-1) and quality of life (90-day BI) without increasing the risk of adverse events.

ObjectiveTo investigate the inhibitory effect of Mahuang Xixin Fuzitang on the migration of dendritic cells (DCs) in mice and its underlying mechanism. MethodMouse bone marrow-derived DCs were isolated and cultured. The morphological changes of the cells at different stages were observed under a microscope, and the CD11c+ proportion was detected by flow cytometry to identify DC purity. Cells were treated with Mahuang Xixin Fuzitang (1, 2, 5, 10, 20, 40, 50, 100 g·L-1) for 24 hours, and the effect of Mahuang Xixin Fuzitang on cell proliferation was assessed using the cell counting kit-8 (CCK-8) assay to determine the appropriate concentrations for treatment. After modeling by lipopolysaccharide (LPS) induction, DCs were divided into a blank group, a model group, and Mahuang Xixin Fuzitang groups (2, 4, 8 g·L-1). The expression of surface molecules CD80, CD86, and major histocompatibility complex-Ⅱ (MHC-Ⅱ) were detected by flow cytometry. Transwell chamber assay was used to observe cell migration. The levels of chemokine C-C-primitive receptor 7 (CCR7) and chemokine C-X-C-primitive receptor 4 (CXCR4) on the cell surface were detected by enzyme-linked immunosorbent assay (ELISA). The expression of filamentous actin (F-actin) in the cell microfilament cytoskeleton was detected by immunofluorescence (IF) staining. Real-time quantitative polymerase chain reaction (Real-time PCR) was employed to determine the mRNA expression levels of Ras homolog family member A (RhoA) and Rho-associated coiled-coil containing protein kinase 1 (ROCK1). Western blot analysis was performed to detect the protein expression of RhoA and ROCK1. ResultCompared with the blank group, the model group exhibited significantly higher expression levels of CD80, CD86, and MHC-Ⅱ (P<0.01), a significantly increased number of cells migrating to the lower chamber (P<0.01), and significantly elevated levels of CCR7 and CXCR4 (P<0.05, P<0.01). Additionally, F-actin expression was significantly increased (P<0.01), and both RhoA and ROCK1 mRNA and protein expression levels were significantly higher (P<0.05, P<0.01). Compared with the model group, treatment with Mahuang Xixin Fuzitang (2, 4, 8 g·L-1) for 24 hours resulted in significantly lower expression levels of CD80, CD86, and MHC-Ⅱ (P<0.01), a significantly reduced number of cells migrating to the lower chamber (P<0.05), and significantly decreased levels of CCR7 and CXCR4 (P<0.05, P<0.01). Furthermore, F-actin expression was significantly reduced (P<0.01), and both RhoA and ROCK1 mRNA and protein expression levels were significantly decreased (P<0.05, P<0.01). ConclusionMahuang Xixin Fuzitang can inhibit the migration of DCs in mice, and its mechanism of action may be related to reducing the activity of the Rho/ROCK signaling pathway, thereby affecting changes in the cell cytoskeleton.

Objective:
To investigate the impact of temperature changes between neighboring days (TCN) on the mortality risk of respiratory diseases, so as to provide the evidence for the study of deaths from respiratory diseases caused by climate change.
Methods:
The monitoring data of deaths from respiratory diseases in Zibo City from 2015 to 2019 were collected from Shandong Provincial Management Information System for Chronic Diseases and Cause of Death Surveillance. The meteorological and air pollutant data of the same period were collected from China Meteorological Data Website and ChinaHighAirPollutants dataset. The effect of TCN on the risk of deaths from respiratory diseases was examined using a generalized additive model combined with a distributed lag non-linear model, and subgroup analyses for gender and age were conducted. The disease burden attributed to TCN at different intervals was assessed by calculating attributable fraction.
Results:
Totally 11 767 deaths from respiratory diseases were reported in Zibo City from 2015 to 2019, including 6 648 males (56.50%) and 5 119 females (43.50%). There were 1 307 deaths aged <65 years (11.11%), and 10 460 deaths aged 65 years and older (88.89%). A monotonically increasing exposure-response relationship was observed between TCN and deaths from respiratory diseases in the general population, females, and the population aged 65 years and older. The 95th percentile of TCN (P95, 3.84 ℃) reached the peak at a cumulative lagged of day 11 (RR=2.063, 95%CI: 1.261-3.376). The results of subgroup analyses showed greater impacts on females and the population aged 65 years and older, with cumulative lagged effects peaking at day 12 (RR=3.119, 95%CI: 1.476-6.589) and day 11 (RR=2.107, 95%CI: 1.260-3.523). The results of attributional risk analysis showed that next-day warming might increase the attributable risk of deaths from respiratory diseases, and next-day cooling might decrease the attributable risk.
Conclusion
Next-day warming may increase the mortality risk of respiratory diseases, and has greater impacts on females and the population aged 65 years and older.
