AIM:To evaluate the effects of periocular injection of triamcinolone acetonide combined with dexamethasone on ocular surface function and tear dynamics in patients with thyroid-associated ophthalmopathy(TAO).METHODS: In this single-center retrospective study, 26 TAO patients(52 eyes)treated between September 2020 and September 2023 received periocular injections of triamcinolone acetonide(20 mg)and dexamethasone(2.5 mg). Clinical parameters, including clinical activity score(CAS), ocular surface disease index(OSDI), Schirmer I test(SⅠt), tear film breakup time(BUT), tear meniscus height(TMH), corneal fluorescein staining(FL), meibomian gland loss, and lipid secretion score, were assessed at baseline, 1 wk, and 1 mo post-injection.RESULTS: There were statistically significant differences in CAS, OSDI, SⅠt, BUT, TMH, FL score, and meibomian gland secretion score before and after injection in the included patients(all P<0.05). At 1 wk after injection, there were differences in CAS, OSDI, SⅠt, BUT, TMH, FL score, and meibomian gland secretion score compared with those before injection(all P<0.0167). At 1 mo after injection, there were differences in CAS, OSDI, SⅠt, BUT, TMH, FL score, and meibomian gland secretion score compared with those at 1 wk after injection(all P<0.0167). At 1 mo after injection, there were no differences in CAS, OSDI, SⅠt, BUT, TMH, FL score, and meibomian gland secretion score compared with those before injection(all P>0.05). There was a difference in meibomian gland dropout score before and after injection in the included patients(P<0.05), but pairwise comparisons showed no differences(P=0.900, 0.306). During the treatment period, 1 patient experienced transient elevation of intraocular pressure(25 mmHg), which was alleviated after control with intraocular pressure-lowering medication, and no cases of secondary glaucoma occurred.CONCLUSION: Periocular injection of triamcinolone acetonide combined with dexamethasone provides short-term improvement in ocular surface symptoms, tear film stability and secretion in TAO patients. However, efficacy diminishes over time and does not reverse structural damage. Long-term maintenance therapy is recommended.

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）.

OBJECTIVES: To investigate the mechanism by which transforming growth factor‑β (TGF‑β) regulates major histocompatibility complex class I (MHC-I) expression in hepatocellular carcinoma (HCC) cells and its role in immune evasion of HCC. METHODS: HCC cells treated with TGF‑β alone or in combination with SB-431542 (a TGF-β type I receptor inhibitor) were examined for changes in MHC-I expression using RT-qPCR and Western blotting. A RNA interference experiment was used to explore the role of miR-23a-3p/IRF1 signaling in TGF‑β‑mediated regulation of MHC-I. HCC cells with different treatments were co-cultured with human peripheral blood mononuclear cells (PBMCs), and the changes in HCC cell proliferation was assessed using CCK-8 and colony formation assays. T-cell cytotoxicity in the co-culture systems was assessed with lactate dehydrogenase (LDH) release and JC-1 mitochondrial membrane potential assays, and T-cell activation was evaluated by flow cytometric analysis of CD69 cells and ELISA for TNF-α secretion. RESULTS: TGF‑β treatment significantly suppressed MHC-I expression in HCC cells and reduced T-cell activation, leading to increased tumor cell proliferation and decreased HCC cell death in the co-culture systems. Mechanistically, TGF-β upregulated miR-23a-3p, which directly targeted IRF1 to inhibit MHC-I transcription. Overexpression of miR-23a-3p phenocopied TGF‑β‑induced suppression of IRF1 and MHC-I. CONCLUSIONS We reveal a novel immune escape mechanism of HCC, in which TGF‑β attenuates T cell-mediated antitumor immunity by suppressing MHC-I expression through the miR-23a-3p/IRF1 signaling axis.

Objective:To investigate the mosquito-borne viruses carried by mosquito specimens collected from Huachuan county and Huanan county in Heilongjiang province.Methods:Mosquito samples were collected locally in 2023 and processed in the laboratory. Homogenates of the mosquitoes were inoculated into cells for virus isolation, followed by molecular and bioinformatics analyses of the viral isolates.Results:In 2023, ten viral isolates were obtained from Anopheles sinensis specimens collected in Heilongjiang province, China. Among these isolates, one was identified as Culex flavivirus (CxFV), one as Menghai rhabdovirus (MRV), and eight as Nam Dinh virus (NDiV). The phylogenetic analysis showed that CxFV belongs to genotype I and is clustered with the strains isolated from Liaoning province in 2011 and Ningxia Hui autonomous Region in 2019 in the same evolutionary branch, with amino acid similarity ranging from 98.2% to 99.2% and nucleotide similarity ranging from 98.8% to 99.2%. The MRV strain belongs to the same evolutionary subclade as the strain detected in Guangdong, with both nucleotide and amino acid similarity of 98.0%. Eight NDiV isolates clustered with the South Korean isolates on the same evolutionary branch, forming an independent evolutionary sub-branch. The nucleotide similarity among these eight isolates ranged from 98.5% to 99.7%, while the amino acid similarity ranged from 98.1% to 99.7%. In comparison, when matched with other NDiV isolates from China, the nucleotide similarity of these eight isolates ranged from 94.1% to 97.8%, and the amino acid similarity ranged from 93.5% to 97.7%.Conclusions:This study represents the first isolation of CxFV, MRV, and NDiV in Heilongjiang province, China, and the findings provide fundamental data for the prevention and control of mosquito-borne viral diseases in this region.

It is well established that blood pressure plays a critical role in the onset of stroke. In recent years, the trajectory of blood pressure has emerged as a novel focus in stroke research, as it is associated with stroke incidence, recurrence, outcomes, and prognosis. Accurately identifying various blood pressure trajectories and exploring their developmental patterns are of significant importance for implementing targeted interventions aimed at reducing the burden of stroke. Consequently, this article reviews the progress of research related to the concept, indicators, and research models of blood pressure trajectories, as well as the mechanisms underlying blood pressure variation and the relationship between blood pressure trajectories and stroke, in order to provide new insights for the prevention and control of stroke.

Objective:To investigate the current status of the implementation of active health management in tumor care in community health service institutions in Shanghai.Methods:This cross-sectional study was conducted in July 2022. A questionnaire was designed based on tumor management practices according to active health principles was designed and distributed to all 247 community health service institutions in 16 administrative districts of Shanghai. Data were collected on tumor screening, establishment of health records for tumor patients, and follow-up practices.Results:Of the 247 questionnaires distributed, 239 were returned, with 228 valid responses (effective response rate: 92.3%). Of the 228 institutions, 72 (31.6%) were located in urban areas, 101 (44.3%) in suburban areas, and 55 (24.1%) in rural areas. Tumor screening was performed by 89.0% (203/228) of the institutions, mainly for colorectal, lung, liver, breast, and gastric cancers. Health records for tumor patients were established by 92.5% (211/228) of institutions. Follow-up of tumor patients was conducted by 99.1% (226/228) of institutions, with 29.6% (67/226) performing 1-2 annual follow-ups. Telephone follow-up was used by 99.1% (224/226) of institutions, while 42.5% (96/226) adjusted the frequency of follow-up based on patients′ Karnofsky Performance Status scores. Targeted health education for patients and families was provided by 84.6% (193/228) of institutions, including exercise guidance (78.8%, 152/193) and psychological support (76.2%, 147/193). No statistically significant differences were observed among urban, suburban, and rural institutions in tumor screening, health record establishment, follow-up frequency, assessment content, follow-up methods, and tumor health education and content (all P>0.05). Conclusions:The coverage of tumor screening in Shanghai′s community health service institutions remains incomplete, the quality of follow-up needs to be improved, and health education programs are not comprehensive. There were no regional differences in tumor screening, health record establishment, follow-up practices, or tumor health education among urban, suburban, and rural populations.
