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 investigate the optimal angle of bedhead elevation during logrolling of patients with severe stroke supported by continuous enteral nutrition via gastric tube administration, and to provide a basis for safe infusion of enteral nutrition in clinical practice.Methods:This study was a prospective study, and the repeated measurement method was used. A total of 154 patients with severe stroke who were admitted to the Neurology Intensive Care Unit of the the 960th Hospital of the Joint Logistic Support Force of the Chinese People′s Liberation Army and treated with continuous enteral nutrition support from January to October 2023 were selected as the study participants by convenience sampling method. The times and duration of cardia reflux in 5 min were observed under ultrasound when the bedhead elevation angle during logrolling of the study participants was 30°, 20°, 10°, and 0°, respectively, and the incidence of reflux and aspiration during the observation period were recorded.Results:A total of 148 patients were eventually included. Among them, 81 were males and 67 were females, aged 38-80 (65.79 ± 10.96) years. There were no significant differences in the incidence of reflux [18.24% (27/148) vs. 12.16% (18/148)] and aspiration [4.05% (6/148) vs. 1.35% (2/148)] when the angle of bedhead elevation during logrolling of patients with continuous enteral nutrition via gastric tube administration was 10° and 20° (all P>0.05). Nevertheless, compared with the incidence of reflux [37.16% (55/148)] and aspiration [(10.81% (16/148)] at the bedhead elevation angle of 0°, those measured at 10° or 20° were significantly different ( χ2 values were 4.91-24.89, all P<0.05). Conclusions:For patients with severe stroke supported by continuous enteral nutrition, bedhead elevation angle of 10° can not only prevent aspiration caused by gastric reflux, but also conform to the labor-saving principle during logrolling, which is the recommended angle of logrolling for patients with severe neurological diseases supported by continuous enteral nutrition.

Objective:To analyze the relationship between health belief and the stages of parental decision-making on childhood 13-valent pneumococcal conjugate vaccine (PCV13) immunization in China.Methods:Cross-sectional multistage survey sampling method was used to select study subjects. The study subjects were parents who were aged 20-45 years and had one and more children ≤5 years old in three cities in China. A self-administered questionnaire designed based on health belief model was used to collect the information. Multinomial logistic regression analysis was used to assess the relationships between perceived susceptibility, perceived severity of illness, perceived effect of PCV13 and stages of parental decision-making on childhood PCV13 immunization.Results:A total of 1 716 valid questionnaires were returned (89.33%). The average age of the study subjects was (35.33±4.95) years, and 79.60% of them were women. In the study subjects, 48.31% had in action, 21.79% were in contemplation and 29.90% were in pre-contemplation. The multinominal logistic regression analysis indicated that high perceived susceptibility ( OR=0.14, 95% CI:0.09-0.22; OR=0.54, 95% CI:0.39-0.76), high perceived severity of illness ( OR=0.55, 95% CI:0.42-0.73), and high perceived effect of PCV13 ( OR=0.27, 95% CI:0.18-0.40; OR=0.51, 95% CI:0.32-0.81) were significantly lower in those who were in contemplation or pre-compared with those who had in action. For study subjects with low perceived susceptibility, high perceived effect of PCV13 might decrease the probabilities of contemplation ( OR=0.53, 95% CI:0.32-0.87) and pre-contemplation ( OR=0.27, 95% CI:0.18-0.41). For those with high perceived susceptibility, perceived severity of illness might decrease the probability of contemplation ( OR=0.43, 95% CI:0.23-0.82). Conclusions:Childhood PCV13 vaccination willingness and level is low in China. It is important to pay greater attention to the intervention on health belief in child parents, such as perceived effect of PCV13, perceived severity of illness, and perceived susceptibility, in health policy development and health promotion.

Objective To observe the imaging findings of embryonal tumor with multilayered rosettes(ETMR).Methods MRI(n=8)and CT(n=6)data of 8 children with pathologically confirmed ETMR were retrospectively reviewed,and the imaging findings were analyzed.Results ETMR present as masses with the maximum diameter of 32-96 mm and clear edges in all 8 cases,located supratentorially in 5 and infratentorially in 3 cases.The supratentorial ETMR were giant cystic solid masses,while the infratentorial ETMR had relatively small volumes.No peritumoral edema was noticed.Cystic solid masses were observed in 6 cases,and the cystic portion presented as low T1WI and high T2WI signals at the edge of the masses.After administration of contrast agents,mild focal uneven enhancement in the solid portion was found in 5 cases,while 1 case was not found enhancement.Among the above 6 cases,the intratumoral bleeding and empty blood vessel shadows within the masses were observed each in 5 cases,while adjacent dura mater invasion was noticed in 3 cases.Two ETMR present as solid masses with focal nodular uneven enhancement,and the enhanced area corresponded to the low signal area on apparent diffusion coefficient(ADC)image,among them,increased choline(Cho)/creatine(Cr)and decreased N-acetyl aspartate(NAA)was found in 1 case.Limited diffusion on diffusion weighted imaging(DWI)were detected in all 8 cases.Among 6 cases who underwent CT scanning,patchy or punctate calcification,corresponding to the low signal area on MRI were detected in 4 cases.Conclusion ETMR mostly present as supratentorial large solid cystic masses with clear edges,and the cystic portion often located at the edge of masses,with characteristic vascular flow voids often accompanied by intratumoral bleeding and some with calcifications but without peritumoral edema,which showed significantly limited diffusion on DWI and weakly inhomogeneous enhancement of the solid part.

Objective To explore the effects of different acupoints,different target organs,and different interventions on acupoint efficacy based on ACU&MOX-DATA platform;To illustrate and visualize whether the above factors have the characteristics of"specific effect"or"common effect"of acupoint efficacy.Methods The multi-source heterogeneous data were integrated from the original omics data and public omics data.After standardization,differential gene analysis,disease pathology network analysis,and enrichment analysis were performed using Batch Search and Stimulation Mode modules in ACU&MOX-DATA platform under the conditions of different acupoints,different target organs,and different interventions.Results Under the same disease state and the same intervention,there were differences in effects among different acupoints;under the same disease state,the same acupoint and intervention,the responses produced by different target organs were not completely consistent;under the same disease state and acupoint,there were differences in effects among different intervention measures.Conclusion Based on the analysis of ACU&MOX-DATA platform,it is preliminary clear that acupoints,target organs,and interventions are the key factors affecting acupoint efficacy.Meanwhile,the above results have indicated that there are specific or common regulatory characteristics of acupoint efficacy.Applying ACU&MOX-DATA platform to analyze and visualize the critical scientific problems in the field of acupuncture and moxibustion can provide references for deepening acupoint cognition,guiding clinical acupoint selection,and improving clinical efficacy.

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 compare the safety and clinical value of warm-water infusion or carbon dioxide(CO2)insufflation in difficult colonoscopy.Methods A collection of 150 patients from May 2021 to October 2023 who underwent unsedated and difficult colonoscopy were randomly divided into warm-water insufflation group(W group,n=50),CO2 insufflation group(C group,n=50)and air insufflation group(A group,n=50).Record the cecal insertion time,the abdominal pain score during the examination and 20 min and 1 h after the examination,the success rate of intubation,the polyps detection rate,the willingness to re-examine and the need for assistance in the three groups.Some patients were randomly selected to record partial pressure of end-tidal carbon dioxide(PetCO2)of pre-examination,the ileocecal and 20 min after the examination to understand CO2 retention in the body.Results The cecal insertion time of group A was longer than that of group W and group C,and group W was shorter than group C.The abdominal pain score of group A was higher than that of group W and group C at each time point,and the abdominal pain score during the examination was lower in the group W compared with group C.The success rate of intubation and the willingness to re-examination in the group A were lower than those in group W and group C,The above differences were statistically significant(P<0.05).However,there was no statistical difference between the the group W and group C in terms of success rate of intubation,willingness to re-examine,and abdominal pain score at 20 minutes and 1 hour after the examination(P>0.05).In the group W,significantly fewer patients required abdominal compression compared with the other two groups,and the rate of position conversion was significantly lower than that in group A(P<0.05).There was no significant difference in the detection rate of polyps among the three groups(P>0.05).In addition,PetCO2 of group C was within the normal range at all time points,and there was no statistical difference compared with the group A(P>0.05).Conclusion Compared with the air group,water or CO2 insufflation colonoscopy is safe and has a high success rate in difficult colonoscopy.It can reduce the patient's abdominal discomfort,especially water insufflation colonoscopy is more suitable for promotion in primary hospitals.
