ObjectiveTo explore the interaction and competitive binding of Homo sapiens long intergenic non-protein-coding RNA 1134 (LINC01134) to CCCTC-binding factor CTCF, affecting the transcription of cyclin-dependent kinase inhibitor (p21) and influencing the proliferation of A549 cells, in order to investigate the possible mechanism of Astragali Radix and Hedyotis diffusa (A-H) in inhibiting A549 proliferation by regulating this axis. MethodsRNA-binding protein immunoprecipitation (RIP) assays were conducted to examine the interaction between LINC01134 and CTCF, and chromatin immunoprecipitation (ChIP) assays were used to study the effect of LINC01134 overexpression on the interaction between CTCF and p21. Stable A549 cell lines (oe-NC and oe-LINC01134) were established using lentiviral transfection, and each group was treated with 10% A-H drug-containing serum. Real-time PCR and Western blot analyses were performed to detect the effects of A-H on the expression of LINC01134, CTCF, and p21 in A549 cells. Cell counting kit-8 (CCK-8) and colony formation assays were used to assess the effects of A-H on A549 cell proliferation via LINC01134. Flow cytometry was employed to evaluate the effects of A-H on the A549 cell cycle through LINC01134, and Western blot was used to detect changes in cell cycle proteins. ResultsCompared with the IgG group, the oe-CTCF group showed a significantly increased abundance of LINC01134 aggregates (P0.01). Compared with the oe-Vector group, p21 abundance in CTCF complexes was significantly reduced in the oe-LINC01134 group (P0.01). Compared with the 10% blank + oe-LINC01134 group, the 10% A-H + oe-LINC01134 group reversed the expression of LINC01134 and p21 (P0.05), but had no significant regulatory effect on CTCF. Compared with the 10% blank + oe-LINC01134 group, the 10% A-H + oe-LINC01134 group reversed cell viability at 72 h (P0.05), inhibited malignant proliferation (P0.05), and reversed the proportions of cells in the G0/G1 and S phases (P0.01). Furthermore, compared with the 10% blank + oe-LINC01134 group, the 10% A-H + oe-LINC01134 group reversed the expression of Cyclin D1, CDK4, Cyclin E, CDK2, phosphorylated retinoblastoma protein (p-Rb), and E2F transcription factor 3 (E2F3) (P0.01). ConclusionA-H regulates the LINC01134-CTCF-p21 axis to block the G1/S phase transition of A549 cell cycle, accelerate cellular senescence, and inhibit malignant proliferation.

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome). MethodsThrough a multi-center randomized controlled methodology design,confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals,such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days,and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale (CARIFS) and the incidence of complications,severe cases, and critical cases. Follow-up observation was conducted on the day of enrollment,48 hours after medication,72 hours after medication, and (6+1) d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group (90 cases) or the control group (90 cases). All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was (5.29±1.25) d,and that in the control group was (5.40±1.68) d,without a statistically significant difference. After five days of intervention,52 cases in the experimental group and 51 cases in the control group converted to negative,without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention,there were statistically significant differences between the experimental group and the control group in three dimensions, including headache,muscle soreness, and the need for extra care (P<0.05). On the (6+1) days after the intervention,the differences in both the experimental group and the control group were statistically significant in 10 dimensions, including sore throat,bad sleep,uncomfortable feeling,poor spirit and fatigue,crying more than usual,the need for extra care,symptom,function,influence on parents,and total score (P<0.05). The comparison results within the group in the dimensional scores of symptom, function, and influence on parents,as well as the CARIFS total score showed that with the delay of follow-up time,scores of both groups decreased significantly,with a statistically significant difference (P<0.01). Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention,the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up,the mean score of the experimental group was lower than that of the control group,with no statistically significant difference. In terms of the incidence of complications,severe cases, and critical cases, there were no complications,severe cases, and critical cases in the two groups,without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome) are not inferior to Oseltamivir Phosphate granules, and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children (heat accumulation in the lung and stomach syndrome).

ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza, and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter, prospective, non-randomized, parallel, controlled trial was conducted from October 2021 to May 2022 in five hospitals, including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness (ILI) cases were collected, and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention, they were assigned to the observation group (108 cases) or the control group (108 cases). Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine (TCM) symptom score scale for influenza, influenza-related emergency (outpatient) visit rate, influenza hospitalization rate, and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled, with 108 in the observation group and 108 in the control group. Primary outcomes: (1) Incidence of ILI: The incidence was 12.0% (13/108) in the observation group and 23.1% (25/108) in the control group, with the observation group showing a significantly lower incidence (χ2=4.6, P<0.05). (2) Influenza confirmation rate: 3.7% (4/108) in the observation group and 4.6% (5/108) in the control group, with no statistically significant difference. Secondary outcomes: (1) TCM symptom score scale: after onset, nasal congestion and runny nose scores differed significantly between the two groups (P<0.05), while other symptoms such as fever, sore throat, and cough showed no significant differences. (2) Influenza-related emergency (outpatient) visit rate: 84.6% (11 cases) in the observation group and 96.0% (24 cases) in the control group, with no significant difference. (3) Time to onset after exposure: The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group, with a statistically significant difference (P<0.05). ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions, Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

Spinal surgical site infection (SSI), especially deep SSI after internal fixation is difficult in treatment, with long course of disease and poor prognosis. At present, there are many controversies in the diagnosis and treatment of spinal SSI, with unsatisfactory overall efficacy of its diagnosis and treatment. Besides, no diagnosis and treatment guideline based on evidence-based medicine has been in existence. To this end, the Spinal Infection Group of the Orthopedic Branch of the Chinese Medical Doctor Association and the Spinal Infection Group of the Spinal Surgery Branch of the Chinese Rehabilitation Medicine Association jointly organized relevant experts to formulate Evidence-based clinical guideline for the diagnosis and treatment of surgical site infection in spinal trauma ( version 2024) based on an evidence-based approach. A total of 10 recommendations were proposed on the diagnosis and treatment of spinal SSI, so as to provide a clinical reference for the diagnosis and treatment of spinal SSI.

Objective To investigate the anti-estrogenic activity of bisphenol A and its substitutes, and to analyze the relevant mechanisms. Methods Bisphenol A and its three most widely used substitutes (bisphenol S, bisphenol F and bisphenol AF) were selected as the docking ligand molecules, and estradiol was used as the control ligand molecule. The ligand molecules docking was simulated with estrogen receptor (ER) α and ERβ using AutoDock software. Results Bisphenol A forms a hydrogen bond with ERα at the His474 residue and with ERβ via three hydrogen bonds at Leu260, His428, and Asn431 residues. Similar to bisphenol A, bisphenol S, bisphenol F, bisphenol AF and estradiol primarily interact with ERα and ERβ through hydrophobic interactions and hydrogen bonds, but with varying optimal binding sites and affinities. The binding forces of the optimal binding sites for bisphenol A, bisphenol F, bisphenol AF, bisphenol S and estradiol with ERα were -4.15, -4.19, -2.73, -4.62 and -5.37 kcal/mol, respectively, and with ERβ were -3.76, -3.91, -2.86, -3.93, and -4.98 kcal/mol, respectively. The affinity ranking for two ERs with these five molecules from high to low was estradiol > bisphenol S> bisphenol F> bisphenol A > bisphenol AF. Conclusion The affinity between bisphenol compounds with ERα and ERβ is mainly based on the hydrophobic interaction with non-polar residues of the receptor and hydrogen bonding with key residues. Bisphenol S, bisphenol F and bisphenol AF showed similar or even stronger endocrine disrupting effects than bisphenol A.
