Objective To investigate the screening results and factors affecting abnormal detection rates among high-risk groups of esophageal cancer and to explore effective intervention measures. Methods We investigated and collected the information on gender, education level, age, marital status, symptoms of reflux esophagitis (heartburn, acid reflux, belching, hiccup, foreign body sensation in the pharynx, and difficulty swallowing), consumption of pickled vegetables, salt use, and esophageal cancer incidence of villagers in a natural village in Wenfeng District, Anyang City, Henan Province. Changes in reflux esophagitis symptoms in the high-incidence area of esophageal cancer before and after 16 years were observed, and the relationship of such changes with esophageal cancer was analyzed. Results In 2008, 711 cases were epidemiologically investigated, including 213 cases with one of the symptoms of reflux esophagitis such as heartburn, acid reflux, belching, hiccups, foreign body sensation in the pharynx, and difficulty swallowing (sorted in accordance with the abovementioned symptoms; if there are multiple symptoms, then the former is taken); 55 cases with at least two related symptoms, among which the most symptom was heartburn in 108 cases (15.1%); followed by acid reflux, belching, etc. In 2024, the same group of people was investigated, and eight people were missing because of relocation. A total of 703 people were successfully investigated, of which 189 cases (26.8%) had one of the symptoms of reflux esophagitis, such as heartburn (sorted in accordance with relevant symptoms, if there are multiple symptoms, then the former will be selected); 167 cases (23.7%) had at least two related symptoms, among which the most symptom was heartburn in 139 cases (19.7%); followed by acid reflux. Over 16 years, among the 703 people investigated, 45 cases had esophageal cancer and they had one or more of the abovementioned symptoms. No significant differences in the reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.26); no significant differences in the composition of reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.299). Conclusion The detection rate of reflux esophagitis-related symptoms in the population in a high-risk area of esophageal cancer has not decreased in the past 16 years, and the high-risk factors still exist. Esophageal cancer is closely related to reflux esophagitis, and clinical practice can provide early diagnosis and treatment for high-risk population.

Objective:To investigate the clinical features, imaging characteristics, surgical strategies, and therapeutic outcomes of otitis media complicated with inflammatory response of local meninges.Methods:A retrospective analysis was conducted on the clinical data of 8 patients with chronic suppurative otitis media complicated with inflammatory response of local meninges, treated by the Department of Otolaryngology, Head and Neck Surgery, PLA General Hospital from 2019 to 2023. Appropriate surgical strategies were selected based on the patient′s clinical manifestations, imaging characteristics, extent of lesions, and facial nerve function. Follow-up was performed postoperatively to assess the therapeutic outcomes.Results:Among the eight patients, there were six males and two females, with an average age of (55.9±12.6) years old. The primary clinical manifestations included otorrhea, hearing loss, facial paralysis, earache, headache, and fever. All patients had a history of chronic suppurative otitis media and tympanic membrane perforation, with varying degrees and types of hearing loss. Seven patients presented with peripheral facial palsy preoperatively, with the House-Brackmann (H-B) grading scale as follows: 4 cases (4/7) in grade Ⅳ, 1 case (1/7) in grade Ⅴ, and 2 cases (2/7) in grade Ⅵ. The mean duration of otorrhea and/or hearing loss was (24.68±12.18) years, while, the average duration of severe headache, aggravated otorrhea and facial paralysis was (2.73±3.92) months. Preoperative high-resolution CT scan of the temporal bone revealed soft tissue shadow in the middle ear and mastoid process, with partial defects in the mastoid cortex. Cranial MRI T1WI showed high signal in the meninges on the affected side, with contrast-enhanced MRI indicating localized meningeal thickening. Four patients (4/8) had diabetes mellitus, and 2 patients (2/8) had a history of middle ear/mastoid surgery. All patients underwent surgical treatment, including thorough removal of lesions, adequate drainage, and facial nerve decompression. Tympanoplasty and hearing reconstruction were performed when conditions permitted. Specifically, 5 patients underwent intact canal wall radical mastoidectomy with facial nerve decompression and tympanoplasty, 2 patients underwent canal wall down mastoidectomy with facial nerve exploration decompression, and 1 patient underwent modified radical mastoidectomy. Postoperatively, patients experienced significant relief and gradual disappearance of ear and head pain. The postoperative H-B grading scale of facial nerve function was as follows: 4 cases in grade Ⅰ (4/8, including 1 case without preoperatively facial palsy), 2 cases (2/8) in grade Ⅱ, and 2 cases (2/8) in grade Ⅲ. Postoperative cranial MRI showed a significant reduction in localized meningeal thickening on the affected side.Conclusions:Patients with long-term chronic suppurative otitis media and/or cholesteatoma who suddenly presented with headache, fever, aggravated otorrhea, and facial paralysis should be suspected of having inflammatory response of local meninges. High-resolution CT of temporal bone and cranial MRI provide crucial diagnostic information. Early surgical exploration and thorough lesion removal are effective treatment methods.

OBJECTIVES: To investigate the potential circular RNA (circRNA)-microRNA (miRNA)-messenger RNA (mRNA) immune regulatory network in childhood allergic asthma by analyzing microarray datasets. METHODS: GEO database was used to obtain the datasets of circRNA, miRNA, and mRNA from children with allergic asthma and healthy controls. The Limma package was used to identify differentially expressed circRNA (DEcircRNA), miRNA (DEmiRNA), and mRNA (DEmRNA). ENCORI and other tools were used to predict and construct the regulatory network of endogenous RNA. The DAVID database was used to perform GO and KEGG enrichment analyses, and CIBERSORT and Pearson were used to identify genes associated with immune cell infiltration. RESULTS: A total of 130 DEcircRNAs, 40 DEmiRNAs, and 802 DEmRNAs were identified between the asthma and control groups, and a regulatory network consisting of 12 circRNAs, 7 miRNAs, and 75 mRNAs was established. The GO analysis showed that the differentially expressed genes were mainly involved in the regulation of growth and development, and the KEGG analysis showed that they were mainly involved in the mTOR signaling pathway. The CIBERSORT analysis showed that compared with the control group, the asthma group had higher percentages of CD8⁺ T cells and resting NK cells and lower percentages of resting CD4⁺ memory T cells and activated mast cells. In addition, the Pearson correlation analysis identified six key mRNAs that were positively correlated with immune cell infiltration. CONCLUSIONS The ceRNA immune regulatory network constructed in this study provides a basis for research on the mechanism of childhood allergic asthma and potential therapeutic targets.

Amorphous solid dispersion (ASD) is one of the most effective formulation approaches to enhance the water solubility and oral bioavailability of poorly water-soluble drugs. However, maintenance of physical stability of amorphous drug is one of the main challenges in the development of ASD. Crystallization is a process of nucleation and crystal growth. The nucleation is the key factor that influences the physical stability of the ASD. However, a theoretical framework to describe the way to inhibit the nucleation of amorphous drug is not yet available. We reviewed the methods and theories of nucleation for amorphous drug. Meanwhile, we also summarized the research progress on the mechanism of additives influence on nucleation and environmental factors on nucleation. This review aims to enhance the better understanding mechanism of nucleation of amorphous drug and controlling over the crystal nucleation during the ASD formulation development.

Objective To explore the efficacy and safety of recombinant human anti-severe acute respiratory syn-drome coronavirus 2(anti-SARS-CoV-2)monoclonal antibody injection(F61 injection)in the treatment of patients with coronavirus disease 2019(COVID-19)combined with renal damage.Methods Patients with COVID-19 and renal damage who visited the PLA General Hospital from January to February 2023 were selected.Subjects were randomly divided into two groups.Control group was treated with conventional anti-COVID-19 therapy,while trial group was treated with conventional anti-COVID-19 therapy combined with F61 injection.A 15-day follow-up was conducted after drug administration.Clinical symptoms,laboratory tests,electrocardiogram,and chest CT of pa-tients were performed to analyze the efficacy and safety of F61 injection.Results Twelve subjects(7 in trial group and 5 in control group)were included in study.Neither group had any clinical progression or death cases.The ave-rage time for negative conversion of nucleic acid of SARS-CoV-2 in control group and trial group were 3.2 days and 1.57 days(P=0.046),respectively.The scores of COVID-19 related target symptom in the trial group on the 3rd and 5th day after medication were both lower than those of the control group(both P＜0.05).According to the clinical staging and World Health Organization 10-point graded disease progression scale,both groups of subjects improved but didn't show statistical differences(P＞0.05).For safety,trial group didn't present any infusion-re-lated adverse event.Subjects in both groups demonstrated varying degrees of elevated blood glucose,elevated urine glucose,elevated urobilinogen,positive urine casts,and cardiac arrhythmia,but the differences were not statistica-lly significant(all P＞0.05).Conclusion F61 injection has initially demonstrated safety and clinical benefit in trea-ting patients with COVID-19 combined with renal damage.As the domestically produced drug,it has good clinical accessibility and may provide more options for clinical practice.
