BACKGROUND: Meningeal metastasis (MM) is a form of malignant metastasis where tumor cells spread from the primary site to the pia mater, dura mater, arachnoid, subarachnoid space, and other cerebrospinal fluid compartments. Lung cancer is one of the most common malignant tumor types with MM. MM not only signifies that the lung cancer has progressed to an advanced stage but also leads to a range of severe clinical symptoms due to meningeal involvement. Currently, the risk factors associated with the development of MM are not fully elucidated. The aim of this study was to investigate the risk factors for MM in patients with lung adenocarcinoma (LUAD) who underwent non-surgical interventions, in order to identify LUAD patients at high risk for MM. METHODS: This retrospective study analyzed the clinical data of patients diagnosed with LUAD at the First Affiliated Hospital of Zhengzhou University from January 2020 to July 2024. Missing data were imputed using multiple imputation methods, and risk factors were identified through LASSO, univariate, and multivariate Logistic regression analyses. RESULTS: A total of 170 patients with LUAD were included in this study and divided into two groups: 87 patients with MM and 83 patients without MM. Univariate and multivariate Logistic regression analyses revealed that younger age at diagnosis (P=0.004), presence of the epidermal growth factor receptor (EGFR) L858R gene mutation (P=0.008), and concurrent liver metastasis at baseline (P=0.004) were independent risk factors for developing MM in LUAD patients who did not undergo surgical intervention. Conversely, higher baseline globulin levels (P=0.039) and the presence of the anaplastic lymphoma kinase (ALK) gene mutation (P=0.040) were associated with a reduced risk of MM development. CONCLUSIONS Age at diagnosis, EGFR L858R mutation status, ALK gene mutation status, concurrent liver metastasis, globulin levels at baseline were significantly associated with the risk of developing MM in patients with LUAD patients who did not undergo surgical intervention. For patients diagnosed at a younger age, carrying the EGFR L858R mutation, or presenting with baseline liver metastasis, early implementation of tertiary prevention strategies for MM is crucial. Regular monitoring of MM status should be conducted in these high-risk groups.

Objective To compare the reflux characteristics between reflux esophagitis (RE) patients with Los Angeles (LA) classification grade A and grades B/C based on esophageal pH-impedance monitoring results. Methods A total of 74 RE patients at Zhongshan Hospital (Xiamen Branch), Fudan University from June 2021 to June 2024 were enrolled, and were divided into the LA-A group (n＝46) and the LA-B/C group (n＝28) based on the endoscopic diagnosis results. The general clinical data, symptom questionnaire score, and esophageal 24-hour pH-impedance monitoring results were compared between the two groups. Results There were no statistically significant differences in demographic data and the response rate of acid suppression therapy between the two groups. 24-hour esophageal pH-impedance monitoring results showed that there were no statistically significant differences in upright, supine, and total reflux indices, including reflux episodes, acid exposure time (AET), AET percentage (AET%), long acid reflux episodes, longest reflux duration, and total DeMeester score between the two groups. There were no statistically significant differences in distal reflux episodes, proximal reflux episodes, and high reflux (acid, weak acid, and non-acidic reflux) episodes, mean nocturnal baseline impedance (MNBI) between the two groups. The rates of pathological reflux (AET%≥6%) in LA-A group and LA-B/C group were 67.4% and 71.4%, respectively; there were no statistically significant differences in the ratio of AET% composition and the count of impedance reflux exceeding 80 during 24 h between the two groups. Conclusions LA-A grade RE based on the endoscopic diagnosis facilitates the identification of gastroesophageal reflux disease in the Chinese population

Objective:To explore the effect of comprehensive moxibustion with Huolong cupping in patients with lung-spleen qi deficiency type allergic rhinitis.Methods:This study was a randomized controlled trial. From October 2022 to April 2023, convenience sampling was used to select 66 patients with lung-spleen qi deficiency type allergic rhinitis who visited the Otolaryngology Head and Neck Clinic of Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine as the research subject. The patients were randomly divided into an experimental group ( n=33) and a control group ( n=33). Both groups received routine oral Chinese medicine treatment. On the basis of routine treatment, the experimental group performed comprehensive moxibustion with Huolong cupping on the meridians of the Du meridian and bladder meridian. This study compared the scores of Nasal Airway Resistance (NAR), Total Nasal Symptom Score (TNSS), Visual Analogue Scale (VAS), and Chinese version of Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) between two groups of patients before and after intervention. Results:Eventually 30 patients in each of the experimental group and control group completed the study. After intervention, the NAR score of the experimental group was lower than that of the control group, and the difference was statistically significant ( P<0.05). Repeated measures analysis of variance showed that with the increase of treatment time, the TNSS, VAS, and RQLQ scores of the experimental group were lower than those of the control group with statistical differences ( P<0.05), and the time effect, inter group effect, and interaction effect were statistically significant ( P<0.05) . Conclusions:Huolong cupping comprehensive moxibustion can reduce nasal resistance, meliorate nasal symptoms and accompanying nasal symptoms, and improve the quality of life of patients.

Objective:To observe the effects of electroacupuncture(EA)on gut microbiota and serum inflammatory factors interleukin(IL)-1β and tumor necrosis factor(TNF)-α in Crohn disease(CD)model rats. Methods:Thirty-six Sprague-Dawley rats were randomly divided into a normal control(NC)group with 10 rats and a modeling group with 26 rats.In the modeling group,the CD rat model was prepared with 2,4,6-trinitrobenzene sulfonic acid(TNBS)enema.After successful modeling,the rats were randomly divided into a CD model(CD)group,an EA group,and a Western medicine(WM)group.The NC and CD groups received no treatment;the EA group was treated with EA for 20 min each time,with 7 consecutive days'intervention;the WM group received mesalazine enteric-coated tablet solution by gavage once a day for 7 d.The changes in body mass and disease activity index(DAI)were observed.Serum IL-1β and TNF-α were determined by enzyme-linked immunosorbent assay.Hematoxylin-eosin staining was used to observe the pathological changes of colon tissues,and 16S rDNA sequencing was used to analyze the structural changes of gut microbiota. Results:Compared with the NC group,the body mass of rats in the CD group decreased(P<0.01),and the DAI score increased(P<0.01);the colon tissue structure was disordered,and many inflammatory cells were present;also,IL-1β and TNF-α increased significantly(P<0.01).As a result,the diversity of gut microbiota decreased,and the abundance of some conditional pathogenic bacteria(such as Prevotella)increased,while the abundance of beneficial bacteria(such as Lactobacillus,Rochella,and Spirillum)decreased.After the intervention,compared with the CD group,the body mass of rats in the EA group and WM group increased(P<0.01);the DAI score decreased(P<0.01),the colon tissue structure improved,and the IL-1β and TNF-α levels decreased(P<0.01);the diversity of gut microbiota increased(P<0.05),and the abundance of some conditional pathogenic bacteria decreased while the abundance of beneficial bacteria increased in the EA group;whereas the diversity of gut microbiota in the WM group was not statistically different(P>0.05). Conclusion:EA can reduce the damage of colon mucosa,regulate the imbalance of gut microbiota,and inhibit the serum inflammatory factor IL-1β and TNF-α expression in CD rats.

Objective:To investigate the value of conventional MRI and high resolution diffusion weighted imaging (DWI) for preoperative discrimination between nasopharyngeal-skull base osteomyelitis (NP-SBO) and locoregionally advanced nasopharyngeal carcinoma (LA-NPC).Methods:From January 2017 to October 2021, 27 patients of NP-SBO and 32 patients of LA-NPC were retrospectively analyzed at the Eye & ENT Hospital of Fudan University. The clinical characteristics and conventional MRI features were collected, and the apparent diffusion coefficient (ADC) values of polygonal (ADC polygonal) and small circle were measured from readout segmentation of long variable echo-trains (RESOLVE) DWI. MRI features included laterality, margin, signal intensity of T 1WI and T 2WI, enhancement degree, component, abscess, deep mucosal white line, bone invasion, lymph nodes involvement and other accompany symphtoms. The independent sample t test, χ 2 test or Fisher exact test were used to compare the features and ADC values of the NP-SBO and LA-NPC groups. The logistic regression was applied to select independent predictors in the distinguishing LA-NPC from NP-SBO. Then, the conventional MRI model, ADC model and conventional MRI in combination with ADC model were built. The area under the receiver operating characteristic curve (AUC) of models were compared using DeLong test. Results:The age, diabetic status, cranial nerve deficits, inner component, abscess, deep mucosal white line, lymph nodes involvement and ADC polygonal were significantly different between NP-SBO and LA-NPC groups ( P<0.05). The logistic regression analysis showed that ADC polygonal (OR=0.972, 95%CI 0.951-0.993, P=0.011) and abscess (OR=0.101, 95%CI 0.013-0.774, P=0.027) were the independent predictors in the discrimination of NP-SBO and LA-NPC. The AUC (95%CI) of conventional MRI model (abscess), ADC model (ADC polygonal) and combination model were 0.634 (0.499-0.756), 0.870 (0.757-0.943), and 0.925(0.829-0.979), respectively. The AUC of combination model was higher than that of conventional MRI model ( Z=4.77, P<0.001), while there was no difference between combination model and ADC model ( Z=1.87, P=0.062). The AUC of conventional MRI model was lower than that of ADC model ( Z=2.84, P=0.005). Conclusion:Conventional MRI in combination with RESOLVE DWI shows good performance in differentiating between NP-SBO and LA-NPC, especially for abscess in combination with ADC polygonal value.

Objective:To explore the correlation between serum creatinine/cystatin C(Scr/CysC)ratio and sarcopenia, and search for serum markers specific to sarcopenia.Methods:A retrospective case-control study of 142 hospitalized patients in the Department of Geriatrics, Xiangya Second Hospital, Central South University from November 2020 to February 2022 were collected, including 43 sarcopenia cases and 99 non sarcopenia cases.The correlation between Scr/CysC ratio and sarcopenia was analyzed and explored.Results:The Scr/CysC ratio of 71.5±12.5 in the sarcopenia group was significantly lower than that of 81.9±15.8 in the non-sarcopenia group( t=3.823, P<0.001), and Scr/CysC was positively correlated with muscle mass and grip strength( r=0.52, 0.69, both P<0.001).The results of the analysis of receiver operating characteristic curves of the subjects showed that in male inpatients, the area under the curve(AUC)of the Scr/CysC ratio in the diagnosis of sarcopenia was 0.770(95% CI: 0.655 to 0.886, P<0.001), with a diagnostic reference value of 80.97, which gave a sensitivity of 72.2% and a specificity of 68.4%.In female inpatients the AUC was 0.621(95% CI: 0.474 to 0.768, P=0.099), with a diagnostic reference value of 65.20, giving a sensitivity of 77.8% and a specificity of 58.3%. Conclusions:The serum Scr/CysC ratio may be a serum marker for male sarcopenia patients, and sarcopenia may be considered when it is below 80.97; The diagnostic value in female sarcopenia needs further research.

Hepatitis B virus (HBV) infection can cause a series of severe liver diseases such as chronic hepatitis B, liver cirrhosis and hepatocellular carcinoma, remaining one of most serious worldwide public health problems. Autophagy is a conserved lysosome-dependent degradation pathway in eukaryotic cells and plays a critical role in host innate immune response. Multiple processes in the life cycle of HBV, including viral replication, maturation and secretion, are closely related to autophagy. Autophagy can regulate the assemble, envelopment and secretion of HBV in human hepatocytes and participate in innate and adaptive immune responses to clear HBV. HBV induces strong autophagy in human hepatocytes and escapes autophagic degradation through certain mechanisms. This review summarized the progress in autophagy and autophagic degradation regulated by HBV infection, hoping to provide a theoretical reference for further understanding the mechanism of autophagy regulated by HBV infection and developing novel strategies for anti-HBV therapy.

Objective:To build and validate a radiomics and clinical nomogram for preoperative discrimination between low- and high-grade sinonasal squamous cell carcinoma (SNSCC).Methods:From January 2017 to May 2021, 167 SNSCC patients including 78 low-grade (grade Ⅰ or Ⅱ) and 89 high-grade (grade Ⅲ) were retrospectively analyzed at the Eye & ENT Hospital of Fudan University. All patients were randomly divided into a training cohort ( n=117, 64 high-grade and 53 low-grade SNSCC) and a validation cohort ( n=50, 25 high-grade and 25 low-grade SNSCC) in a ratio of 7∶3 using a stratified sampling method. The radiomics features were extracted in contrast enhanced T 1WI with manual segmentation of lesions. The least absolute shrinkage and selection operator regression was used to reduce the dimension of the radiomics features and then the radiomics model was built to predict SNSCC histological grade in training cohort. Independent clinical predicting factors were screened using logistic regression and the clinical model was built. The clinical-radiomics model was built by the radiomics features and clinical factors in the training cohort based on logistic regression and the nomogram was drawn. The receiver operator characteristic curves were drawn to evaluate the performance of clinical model, radiomics model and nomogram. The calibration curve was used to evaluate the consistency between the nomogram prediction and the actual observation risk, and the decision curve analysis (DCA) was used to evaluate the clinical applicability of the nomogram. Results:Using logistic regression analysis, the clinical model was built by the tumor primary site (OR value 7.376, 95%CI 2.517-21.618, P<0.001) and TNM stage (OR value 10.020, 95%CI 3.654-27.472, P<0.001) and the area under the curve (AUC) in the training cohort and validation cohort were 0.798 and 0.784, sensitivity were 84.4% and 84.0%, specificity were 58.5% and 68.0%, respectively. Based on the contrast enhanced T 1WI, a total of 9 radiomics features were screened for establishing the radiomics model. The AUC of radiomics model were 0.833 (sensitivity 82.8%, specificity 73.6%) and 0.851 (sensitivity 92.0%, specificity 68.0%) in the training and validation cohorts. The nomogram based on the clinical-radiomics model predicted histological grade with the highest AUC in the training cohort (AUC 0.920, sensitivity 89.1%, specificity 83.0%) and validation cohort (AUC 0.912, sensitivity 92.0%, specificity 84.0%). The calibration curve of the nomogram was close to the ideal line in both training and validation cohorts. DCA showed that the use of nomogram with a threshold in the range of <85% in training cohort, in the range of 20%-65%, 72%-90% in validation cohort, had a greater clinical application value in predicting the SNSCC histological grade. Nomogram model had a better clinical net benefit than the clinical and radiomics models. Conclusion:Nomogram combining clinical factors (tumor primary site and TNM stage) with radiomics features obtained from contrast enhanced T 1WI has a better ability for predicting histological grade of SNSCC than clinical and radiomics models.

Objective In this study, we aimed to translate and revise the Summary of Diabetes Self-Care Activities( SDSCA) and the Confidence In Diabetes Self-care( CIDS) scales, to test the reliability and validity of the two scales in Chinese adult type 1 diabetes( T1D) patients. Methods In the first step, Chinese versions( C-SDSCA and C-CIDS) were developed conceptually equivalent to the English versions. And the investigation was conducted in 100 patients from Guangdong T1D Translational Medicine Study. 15 of them were randomly chosen to be retested 4 weeks later. Cronbach's α were used to assess reliability, and factor analysis to its validity. The relationship between scores of C-SDSCA and C-CIDS were analyzed using Spearman correlation analysis. Results The overall Cronbach's α of C-SDSCA was 0.72 and the retest reliability was 0.95( sub-scale:0.67-1.00) . 4 common factors were extracted by factor analysis, and the cumulative contribution was 87.39％. As for C-CIDS, the general Cronbach's α was 0.84 and the retest reliability was 0. 70 ( sub-scale: 0. 49-0. 86 ) . 6 common factors were extracted and the cumulative contribution was 75.41％. The score of the two scales was positively related(r=0.61, P<0.01). Conclusion The revised C-CIDS and C-SDSCA scales turn out to have good reliability and validity, and can be used as instruments to assess diabetes self-management efficacy and self-care activities of Chinese adult T1D patients.

Gastroesophageal reflux disease (GERD) is a very common disease, and the prevalence in the general population has recently increased. GERD is a chronic relapsing disease associated with motility disorders of the upper gastrointestinal tract. Several factors are implicated in GERD, including hypotensive lower esophageal sphincter, frequent transient lower esophageal sphincter relaxation, esophageal hypersensitivity, reduced resistance of the esophageal mucosa against the refluxed contents, ineffective esophageal motility, abnormal bolus transport, deficits initiating secondary peristalsis, abnormal response to multiple rapid swallowing, and hiatal hernia. One or more of these mechanisms result in the reflux of stomach contents into the esophagus, delayed clearance of the refluxate, and the development of symptoms and/or complications. New techniques, such as 24-hour pH and multichannel intraluminal impedance monitoring, multichannel intraluminal impedance and esophageal manometry, high-resolution manometry, 3-dimensional high-resolution manometry, enoscopic functional luminal imaging probe, and 24-hour dynamic esophageal manometry, provide more information on esophageal motility and have clarified the pathophysiology of GERD. Proton pump inhibitors remain the preferred pharmaceutical option to treat GERD. The ideal target of GERD treatment is to restore esophageal motility and reconstruct the anti-reflux mechanism. This review focuses on current advances in esophageal motor dysfunction in patients with GERD and the influence of these developments on GERD treatment.
