Objective To analyze the current status of dietary quality in patients with chronic atrophic gastritis (CAG), and to explore the influencing factors of dietary quality. Methods A retrospective study was conducted on 550 patients with CAG admitted to the hospital from April 2021 to April 2024. Self-made basic data questionnaire, dietary balance index (DBI), and hospital anxiety and depression scale-anxiety subscale (HADS-A) were used for investigation. Multivariate linear regression analysis was applied to analyze the influencing factors of DBI-lower bound score (LBS). Results The average score of DBI-LBS in 550 patients with CAG was (31.45±8.53) points. There were significant differences in DBI-LBS scores among CAG patients in terms of age, body mass index (BMI), Helicobacter pylori (HP) infection, marital status, drinking history, smoking history, CAG severity, HADS-A score and concurrent gastrointestinal diseases (P<0.05). Multivariate linear regression analysis of the above influencing factors indicated that BMI, smoking history, HADS-A score and CAG severity were independent influencing factors of DBI-LBS score in CAG patients (P<0.05). Conclusion The general dietary quality is not optimistic in CAG patients, showing a moderate deficiency in dietary intake. BMI, disease severity and psychological status of patients are independent factors affecting dietary quality.

[Objective] To explore the association between methyltransferase-like 3 (METTL3) and prostate cancer (PCa) prognosis, so as to establish a novel prognostic prediction model for PCa. [Methods] Public datasets and PCa tissue microarray were used to evaluate the gene and protein expressions of METTL3, the association between METTL3 and Gleason score (GS), and the ability of METTL3 to predict poor outcomes of PCa.A nomogram was constructed to quantitatively evaluate the prognosis of PCa. [Results] The gene and protein expressions of METTL3 were significantly upregulated in PCa tissues compared to normal tissues (P<0.05). Moreover, the expressions of METTL3 were significantly higher in high-risk PCa tissues (GS>7) compared to low-moderate risk PCa tissues (GS≤7) (P<0.05). Patients with elevated expressions of METTL3 exhibited poorer short-term and long-term progression-free and overall survival outcomes when compared to those with lower expressions of METTL3 (P<0.05). In addition, a risk model composed of 7 target genes regulated by METTL3 N6-methyladenine (m6A) modification was established.The 7 target genes were closely associated with the cell cycle process.The protein expression of METTL3 exhibited a significant positive correlation with the protein expression of cell cycle protein B1 (CCNB1) (r=0.30, P=0.002 5). [Conclusion] METTL3 exhibits the potential as a prognostic predictor for PCa, which may affect PCa prognosis through the regulation of the expressions of target genes closely associated with the cell cycle process via m6A modification.

This study was designed to investigate the effects of wheat grain moxibustion on the immune function of mice immunosuppressed by cyclophosphamide,and to delve into the potential mechanisms by analyzing factors related to NF-κB signaling pathway.Sixty SPF-grade ICR mice were randomly allocated into four groups:blank group,model group,traditional Chinese medicine group and wheat grain moxibustion group,with 15 mice in each group.Immunosuppression was induced in mice of the model,traditional Chinese medicine and wheat grain moxibustion groups by intraperitoneal injection of cyclophosphamide at 80 mg/kg daily for three days,while mice of the blank group received an equivalent volume of saline.The traditional Chinese medicine group was treated with oral administration of Zhēn Qí Fú Zhèng granules,and the wheat grain moxibustion group was treated with wheat grain moxibustion at"Da Zhui,"bilateral"Zu San Li,"and bilateral"San Yin Jiao"once a day for seven consecutive days.After corresponding treatment,spleens were harvested from the mice of different groups for pathological examination,and enzyme-linked immunosorbent assay(ELISA)was utilized to measure the serum levels of IL-2,IL-4,TNF-α and IFN-γ.Additionally,Western blot analysis was conducted to assess the protein expression levels of IκBα and P-IκBα in spleen tissue.Compared with the blank group,mice in the model group exhibited poorer general conditions,significantly reduced white blood cell(WBC)count(P＜0.01),extensive damage in spleen tissue,significant decreases in serum IL-4 and IL-2 concentrations,increases in TNF-α and IFN-γ levels(P＜0.01),lower level of P-IκBα protein in spleen tissue(P＜0.01),and higher level of IκBα protein(P＜0.01).These changes mentioned above were reversed in mice of both the wheat grain moxibustion group and the traditional Chinese medicine group(P＜0.01).Compared to the traditional Chinese medicine group,on the last day of treatment,the wheat grain moxibustion group showed slightly higher WBC counts(P＜0.05),better tissue repair,and lower levels of IFN-γ(P＜0.01).In conclusion,wheat grain moxibustion can affect the activity of NF-κB signaling pathway by regulating the relative expression of IκBα and P-IκBα,and then regulate the immune response of the body,thus play a role in alleviating the immunosuppression caused by cyclophosphamide.

Objective:To investigate the safety and feasibility of endoscopic thyroidectomy by gasless trans subclavian approach (ETGTA) in treatment of papillary thyroid carcinoma (PTC) .Methods:The clinical data of 148 patients with PTC radical operation admitted to the Department of Thyroid and Breast Surgery, Nanjing Hospital of Traditional Chinese Medicine Affiliated to Nanjing University of Chinese Medicine from Jul. 2020 to May. 2022 were retrospectively analyzed. They were divided into subclavian approach group (53 cases) and modified miccoli group (95 cases) according to different surgical approaches. The operation time, intraoperative bleeding volume, postoperative drainage flow, postoperative drainage days, postoperative hospital stay, postoperative complications and cosmetic satisfaction were recorded in the 2 groups. Statistical software was used to analyze the results, including t test, Mann-Whitney U test, χ2 test, etc. P<0.05 was considered statistically significant. Results:There were no significant differences in age, sex ratio, maximum diameter, stage, tumor lesion or surgical method between the 2 groups ( P>0.05). The postoperative drainage days increased in the subclavian group than in the modified miccoli group (4.57±2.45 vs. 2.98±1.07) ( P<0.01), but there was no statistical difference in operation time, intraoperative blood loss, postoperative drainage, or postoperative hospital stay between the two groups ( P>0.05). The incidence of swallowing discomfort at 1 month [5.6% (3/53) vs. 18.9% (18/95), P=0.04] and 3 months [0% (0/53) vs. 7.4% (7/95) , P=0.04], anterior cervical area tightness or stiffness at 1 month [0% (0/53) vs. 11.6% (11/95), P=0.01] and 3 months [0% (0/53) vs. 8.4% (8/95), P=0.03] were less than that of the modified miccoli group, and the difference was statistically significant (4.1±0.7 vs. 2.4±0.8) ( P<0.01), and the cosmetic satisfaction of the subclavian approach was higher than that of the modified miccoli group ( P<0.01). There was no significant difference in postoperative temporary recurrent laryngeal nerve injury, postoperative 3d neck pain, postoperative hand-foot numbness or postoperative hematoma between the two groups (all P>0.05) . Conclusion:The radical resection of papillary thyroid carcinoma without inflatable subclavicular approach is safe and feasible, with few postoperative complications and better cosmetic effect, which is worth popularizing.

With the change of lifestyle,the obese population is gradually increasing,and the prevalence of type 2 diabetes mellitus(T2DM)is increasing year by year,while the age of onset is declining year by year.Diabetic retinopathy(DR),as one of the common complications of T2DM,has a serious impact on the quality of life of patients.At present,there is no way to predict and completely stop the progression of DR.Studies have shown that vitamin D supplementation can effectively alleviate DR in vitamin D deficiency patients,which is expected to become a new idea and method to predict and treat DR.This article-reviews the role of vitamin D in the occurrence and development of DR,as well as its therapeutic effect and mechanism on DR,in order to provide a basis for the application of vitamin D supplementation in the prevention and treatment of DR.

Objective:To explore the feasibility of actively screening patients with chronic obstructive pulmonary disease (COPD) among inpatients in county territory-level hospitals based on the collection of comorbidity-related diseases and questionnaire surveys.Methods:This study was a cross-sectional study. From April 1, 2023, to November 30, 2023, a total of 1 392 inpatients who met the screening criteria in county territory-level hospitals within the Western Medical Group of Baiyun District, Guangzhou, were included in the study. General information, disease data, and COPD screening data of the patients were collected. A total of 1 392 questionnaires were distributed, all of which were returned and included in the analysis. Descriptive analysis, comparative analysis, and association rule mining were conducted, including the distribution of general information, distribution of common comorbidity-related diseases in COPD, distribution of questionnaire screening and pulmonary function test results, comparison of screening results based on comorbidity-related diseases grouping, comparison of screening results based on questionnaire screening results grouping, comparison of screening results based on smoking total score grouping, and association rules between screening results and pulmonary function test results and other research data.Results:Among the 1 392 study subjects, 334 cases (24.0%) had a positive self-screening questionnaire for COPD, 44 cases (13.2%) completed pulmonary function tests, and 17 cases (38.6%) were diagnosed with COPD. The positive rate of the screening questionnaire among inpatients was lowest in surgical patients without comorbidity-related diseases and highest in male patients with single/multiple comorbidity-related diseases and symptoms of chronic respiratory system diseases. The group with multiple comorbidity-related diseases had a significantly higher positive rate in the screening questionnaire than the group with single comorbidity-related diseases and the group without comorbidity-related diseases. Only 13.2% of inpatients with a positive screening questionnaire completed pulmonary function tests, with residents covered by medical insurance with multiple comorbidity-related diseases, including cardiovascular diseases, having the lowest rate, and patients with symptoms of chronic respiratory system diseases and single comorbidity-related diseases having the highest rate.Conclusions:Based on the collection of comorbidity-related diseases and questionnaire surveys, it is feasible to actively screen COPD patients among inpatients in county territory-level hospitals. However, efforts are needed to further increase the proportion of inpatients with positive screening questionnaires undergoing pulmonary function tests.

The Ly-6 and uPAR (LU) domain-containing proteins represent a large family of cell-surface markers. In particular, mouse Ly-6A/Sca-1 is a widely used marker for various stem cells; however, its human ortholog is missing. In this study, based on a systematic survey and comparative genomic study of mouse and human LU domain-containing proteins, we identified a previously unannotated human gene encoding the candidate ortholog of mouse Ly-6A/Sca-1. This gene, hereby named LY6A, reversely overlaps with a lncRNA gene in the majority of exonic sequences. We found that LY6A is aberrantly expressed in pituitary tumors, but not in normal pituitary tissues, and may contribute to tumorigenesis. Similar to mouse Ly-6A/Sca-1, human LY6A is also upregulated by interferon, suggesting a conserved transcriptional regulatory mechanism between humans and mice. We cloned the full-length LY6A cDNA, whose encoded protein sequence, domain architecture, and exon-intron structures are all well conserved with mouse Ly-6A/Sca-1. Ectopic expression of the LY6A protein in cells demonstrates that it acts the same as mouse Ly-6A/Sca-1 in their processing and glycosylphosphatidylinositol anchoring to the cell membrane. Collectively, these studies unveil a novel human gene encoding a candidate biomarker and provide an interesting model gene for studying gene regulatory and evolutionary mechanisms.

OBJECTIVE: To analyze the characteristics of genetic variants among children with refractory epilepsy (RE). METHODS: One hundred and seventeen children with RE who had presented at the Affiliated Jinhua Hospital of Zhejiang University School of Medicine from January 1, 2018 to November 21, 2019 were selected as the study subjects. The children were divided into four groups according to their ages of onset: < 1 year old, 1 ~ 3 years old, 3 ~ 12 years old, and >= 12 years old. Clinical data and results of trio-whole exome sequencing were retrospectively analyzed. RESULTS: In total 67 males and 50 females were included. The age of onset had ranged from 4 days to 14 years old. Among the 117 patients, 33 (28.21%) had carried pathogenic or likely pathogenic variants. The detection rates for the < 1 year old, 1 ~ 3 years old and >= 3 years old groups were 53.85% (21/39), 12.00% (3/25) and 16.98% (9/53), respectively, with a significant difference among the groups (χ² = 19.202, P < 0.001). The detection rates for patients with and without comorbidities were 33.33% (12/36) and 25.93% (21/81), respectively (χ² = 0.359, P = 0.549). Among the 33 patients carrying genetic variants, 27 were single nucleotide polymorphisms (SNPs) or insertion/deletions (InDels), and 6 were copy number variations (CNVs). The most common mutant genes were PRRT2 (15.15%, 5/33) and SCN1A (12.12%, 4/33). Among children carrying genetic variants, 72.73% (8/11) had attained clinical remission after adjusting the medication according to the references. CONCLUSION 28.21% of RE patients have harbored pathogenic or likely pathogenic variants or CNVs. The detection rate is higher in those with younger age of onset. PRRT2 and SCN1A genes are more commonly involved. Adjusting medication based on the types of affected genes may facilitate improvement of the remission rate.

Ischemic stroke is a common cerebrovascular disease with high mortality and disability rates. Astrocytes, as the most abundant glial cells in the brain, have the function of maintaining the homeostasis of the central nervous system, which requires precise coupling between neurotransmission and energy metabolism. Therefore, the metabolic crosstalk between astrocytes and neurons plays an important role in the occurrence and development of ischemic stroke. On the one hand, ischemic stroke leads to neuronal excessive excitation, metabolic disorders, and even death, simultaneously promoting changes in astrocyte metabolism profile and increased heterogeneity. On the other hand, the metabolic crosstalk between astrocytes and neurons can also affect the outcome of ischemic stroke. This article reviews the role of the metabolic crosstalk between astrocytes and neurons in ischemic brain injury, and looks forward to potential research directions and treatment targets in the future, in order to provide theoretical reference for the treatment of ischemic stroke.
