Objective: To construct an evaluation index system of cervical cancer prevention and control literacy, so as to provide an assessment tool for cervical cancer prevention and control literacy. Methods: The preliminary framework for cervical cancer prevention and control literacy was designed based on literature review. Twenty-one experts with both theoretical and practical experience in cervical cancer prevention and control were invited to participate in two rounds of Delphi consultation. The weights of indicators were determined by the percentage weighting method and product method, and the response rate, authority level, opinion concentration degree, and coordination degree of experts were evaluated. Results: Twenty-one experts participated in the consultation, including 3 males and 18 females. There were 11 experts with a doctor's degree, 7 with a master's degree and 3 with a bachelor's degree. All of them had senior professional titles and had more than 10 years of working experience. The recovery rates of the two rounds of consultations were 100.00% and 95.24%, the authority coefficients were 0.963 and 0.948, and Kendall's coefficients of concordance were 0.175 and 0.148 (both P<0.05), respectively. The final cervical cancer prevention and control literacy evaluation index system included 3 primary indicators (basic knowledge and concepts: 0.334; healthy lifestyle and behaviors: 0.338; basic skills: 0.328), 12 secondary indicators, with "capability to accurately acquire, comprehend, evaluate and apply health information" having the highest weight (0.166), and 51 tertiary indicators, with "HPV vaccination" (0.086), "consulting on relevant issues" (0.082), and "expressing personal perspectives" (0.080) having relatively higher weights. Conclusion The evaluation index system of cervical cancer prevention and control literacy serves as a valid assessment tool for women of appropriate age, providing the reference for developing targeted health education to enhance cervical cancer prevention and control literacy.

The steroid constituents in the 75% ethanol extract of Cyanotis arachnoidea and their anti-HSV-1 activities in vitro were investigated in this study. The ethyl acetate fraction of the extract was isolated and purified using silica gel, ODS, Sephadex LH-20 column chromatography, and semi-preparative HPLC. Structural identification was conducted based on spectroscopic data. Ten steroid compounds were isolated and identified, namely makisterone A 3-acetate(1), makisterone A 2-acetate(2), makisterone A(3), ajugasterone C 2-acetate(4), ajugasterone C(5), 20-hydroxyecdysone 2-acetate(6), 20-hydroxyecdysone 3-acetate(7), podecdysone C(8), rubrosterone(9), and poststerone(10). Compounds 1 and 2 are new steroid compounds. The anti-HSV-1 activities of compounds 1-10 were evaluated using the CPE inhibition method. Vero cells were used in the experiment, with acyclovir as the positive control. The results showed that compounds 9 and 10 showed anti-HSV-1 activity, with EC_(50) values of 83.11 and 103.62 μg·mL~(-1), respectively.

Glioblastoma (GBM) is the most common and aggressive malignant brain tumor in adults and is poorly controlled. Previous studies have shown that both macrophages and angiogenesis play significant roles in GBM progression, and co-targeting of CSF1R and VEGFR is likely to be an effective strategy for GBM treatment. Therefore, this study developed a novel and selective inhibitor of CSF1R and VEGFR, SYHA1813, possessing potent antitumor activity against GBM. SYHA1813 inhibited VEGFR and CSF1R kinase activities with high potency and selectivity and thus blocked the cell viability of HUVECs and macrophages and exhibited anti-angiogenetic effects both in vitro and in vivo. SYHA1813 also displayed potent in vivo antitumor activity against GBM in immune-competent and immune-deficient mouse models, including temozolomide (TMZ) insensitive tumors. Notably, SYHA1813 could penetrate the blood-brain barrier (BBB) and prolong the survival time of mice bearing intracranial GBM xenografts. Moreover, SYHA1813 treatment resulted in a synergistic antitumor efficacy in combination with the PD-1 antibody. As a clinical proof of concept, SYHA1813 achieved confirmed responses in patients with recurrent GBM in an ongoing first-in-human phase I trial. The data of this study support the rationale for an ongoing phase I clinical study (ChiCTR2100045380).

Objective: To verify effects of rs1061622 at tumor necrosis factor-α receptor II (TNF-RII) gene (TNF-RII) on post-traumatic stress disorder (PTSD) and its interactive effects with PTSD on serum lipids levels in adolescents. Methods: PTSD was measured by PTSD Checklist-Civilian Version (PCL-C) in 699 adolescent survivors at 6 months after Wenchuan earthquake in China. A polymerase chain reaction and restriction fragment length polymorphism assay were utilized for TNF-RII rs1061622 genotyping followed by verification using DNA sequencing. Serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol were tested using routine methods. Results: G (deoxyguanine) allele carriers had higher PCL-C scores than TT (deoxythymidine) homozygotes in female subjects. Female adolescents had higher PCL-C scores than male subjects in TT homozygotes. Predictors of PTSD prevalence and severity were different between G allele carriers and TT homozygotes. Subjects with PTSD had lower TG, TG/HDL-C, TC/HDL-C, and higher HDL-C than adolescents without PTSD in male G allele carriers. G allele carriers had higher TG/HDL-C and TC/HDL-C than TT homozygotes in male adolescents without PTSD, and lower TG and TG/HDL-C in male PTSD patients. G allele carriers had higher TG than TT homozygotes only in female adolescents without PTSD. Conclusion These results suggest reciprocal actions of TNF-RII rs1061622 with other factors on PTSD severity, interplays of TNF-RII rs1061622 with PTSD on serum lipid levels, and novel treatment strategies for PTSD and comorbidities of PTSD with hyperlipidemia among adolescents with different genetic backgrounds of TNF-RII rs1061622 after experiencing traumatic events.

OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

Objective:To investigate the effects of Tiaogan Lifei Decoction on the level of symptom control in patients with bronchial asthma (asthma) treated with moderate and high dosage inhaled glucocorticoids (ICS).Methods:Randomized double-blind placebo controlled prospective study was used. Totally 90 patients with asthma (liver lung disharmony, wind phlegm blocking collateral syndrome) using moderate and high dosage ICS who met the inclusion criteria from January 2020 to December 2021 in Chaoyang District Hospital of Traditional Chinese Medicine in Beijing were divided into two groups according to random number table method, with 45 cases in each group. On the basis of using the original dosage of ICS, the treatment group used Tiaogan Lifei Decoction, while the control group used Tiaogan Lifei Decoction simulant. The course of treatment was 12 weeks. TCM symptom score of both group before and after the treatment was detected; asthma control test (ACT) was used to assess the effects of asthma on the patients; St George's Hospital Respiratory Questionnaire (SGRQ) was used to assess patients' quality of life; the peak expiratory flow rate (PEF) was measured with a peak expiratory flow meter. 2 ml of venous blood was collected for eosinophil (EOS) detection, and the serum allergen specific IgE level was determined by ELISA. The adverse reactions were observed during the treatment and the clinical efficacy was evaluated.Results:During the test, 3 cases and 2 cases in the treatment group and control group lost prevention respectively. 3 cases in the treatment group and 6 cases in the control group withdrew from the trial because of the aggravation of symptoms and the need to increase the dosage of ICS. The total effective rate in the treatment group was 78.6% (33/42), and that in the control group was 55.8% (24/43), with statistical significance ( χ2=4.98, P=0.026). After treatment, the scores of daily activities, early awakening, control and total scores in the treatment group were higher than those in the control group ( t values were 1.76, 1.99, 2.00, 2.69, respectively, P<0.01 or P<0.05); after treatment, the scores of cough, chest tightness, active wheezing, upset, pharyngeal itch and total score in the treatment group were lower than those in the control group ( t values were -5.89, -6.01, -5.66, -4.27, -6.67, -9.05, respectively, P<0.01); SGRQ score in the treatment group was lower than that of the control group ( t=-7.19, P<0.01). No serious adverse reactions occurred during treatment in the two groups. Conclusion:Tiaogan Lifei Decoction is helpful to improve the symptom control level of asthma patients who are using ICS, and effectively improve the quality of life of patients with asthma of liver lung disharmony and wind phlegm obstructing collaterals syndrome.

OBJECTIVES: To study the role and mechanism of autophagy in lipopolysaccharide (LPS)-induced inflammatory response of human alveolar epithelial A549 cells. METHODS: A549 cells were stimulated with LPS to establish a cell model of inflammatory response, and were then grouped (n=3 each) by concentration (0, 1, 5, and 10 μg/mL) and time (0, 4, 8, 12, and 24 hours). The A549 cells were treated with autophagy inhibitor 3-methyladenine (3-MA) to be divided into four groups (n=3 each): control, LPS, 3-MA, and 3-MA+LPS. The A549 cells were treated with autophagy agonist rapamycin (RAPA) to be divided into four groups (n=3 each): control, LPS, RAPA, and RAPA+LPS. The A549 cells were transfected with the Toll-like receptor 4 (TLR4) overexpression plasmid to be divided into four groups (n=3 each): TLR4 overexpression control, TLR4 overexpression, TLR4 overexpression control+LPS, and TLR4 overexpression+LPS. The A549 cells were transfected with TLR4 siRNA to be divided into four groups (n=3 each): TLR4 silencing control,TLR4 silencing, TLR4 silencing control+LPS, and TLR4 silencing+LPS. CCK-8 assay was used to measure cell viability. Western blot was used to measure the protein expression levels of inflammatory indicators (NLRP3, Caspase-1, and ASC), autophagic indicators (LC3B, Beclin-1, and P62), and TLR4. RESULTS: After stimulation with 1 μg/mL LPS for 12 hours, the levels of inflammatory indicators (NLRP3, Caspase-1, and ASC), autophagic indicators (LC3B, Beclin-1, and P62), and TLR4 increased and reached the peak (P<0.05). Compared with the LPS group, the 3-MA+LPS group had reduced expression of autophagy-related proteins and increased expression of inflammation-related proteins and TLR4, while the RAPA+LPS group had increased expression of autophagy-related proteins and reduced inflammation-related proteins and TLR4 (P<0.05). The TLR4 overexpression+LPS group had reduced autophagy-related proteins and increased inflammation-related proteins compared with the TLR4 overexpression control+LPS group, and the TLR4 silencing+LPS group had increased autophagy-related proteins and reduced inflammation-related proteins compared with the TLR4 silencing control+LPS group (P<0.05). CONCLUSIONS In the LPS-induced inflammatory response of human alveolar epithelial A549 cells, autophagic flux has a certain protective effect on A549 cells. TLR4-mediated autophagic flux negatively regulates the LPS-induced inflammatory response of A549 cells.
