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 explore the effect of transcranial direct current stimulation(tDCS)based on music therapy on insomnia. Methods From July,2023 to April,2024,70 patients with insomnia in the Fourth Affiliated Hospital of Soochow Univer-sity were randomly divided into control group(n=35)and observation group(n=35).Both groups accepted mu-sic therapy;moreover,the observation group accepted tDCS,and the control group accepted sham tDCS,for four weeks.They were assessed with Pittsburgh Sleep Quality Index(PSQI)total score and sub-score,Hamilton De-pression Scale 17-item(HAMD-17),Hamilton Anxiety Scale(HAMA),Chinese version of Stress Perception Scale(CPSS);and the relative power of resting-state electroencephalography(EEG)and mean blood flow veloci-ty(Vm)of each cerebral artery with transcranial Doppler were measured before and after treatment. Results Five cases dropped down in the control group,and four in the observation group.PSQI total score and sub-score,HAMD-17 score,HAMA score and CPSS score(|t|>3.503,P<0.01)in the observation group decreased after treatment,and were less in the observation group than in the control group(|t|>2.304,P<0.05),except sleep duration,sleep efficiency and CPSS scores.The relative power of δ and θ increased in the observation group,and decreased in α,β and γ(|t|>6.468,P<0.001),and were better in the observation group than in the control group(|t|>2.395,P<0.05).The Vm of each artery increased in the observation group(|t|>4.624,P<0.001),and were more in the observation group than in the control group(|t|>2.147,P<0.05). Conclusion tDCS based on music therapy may further improve sleep quality and EEG activity,increase cerebral blood flow velocity,and reduce adverse emotions in insomnia patients.

Objective:To observe any effect of repetitive transcranial magnetic stimulation (rTMS) on sleep disorders among children with cerebral palsy (CP).Methods:A total of 102 children with CP and disordered sleep were randomly divided into an experimental group and a control group, each of 51. All were given routine rehabilitation and sleep health education, but the experimental group additionally received rTMS for two weeks. The polysomnography (PSG) results of the two groups were recorded and analyzed.Results:The PSG parameters had improved greatly in both groups after the treatment. The percentage of N2 sleep (depth of sleep during light sleep) in the severe cerebral palsy group and of N3 sleep (depth of sleep during deep sleep) in the moderate cerebral palsy group had increased significantly more than in the mild cerebral palsy group, on average. After the intervention the percentages of N2 and N3 in those with mixed cerebral palsy and of N3 in those with involuntary motor cerebral palsy had increased significantly more than in those with spastic cerebral palsy, on average.Conclusion:rTMS treatment can improve the sleep disorders of children with cerebral palsy, especially N2 sleep among children with moderate to severe cerebral palsy, N3 sleep in cases of mixed or dyskinetic CP.

Objective:To document the clinical features of children with cerebral palsy (CP) using magnetic resonance imaging (MRI).Methods:The gross motor functioning of 325 children diagnosed as having CP was graded using the gross motor function classification system (GMFCS). The GMFCS grades were correlated with MRI results in univariate and multivariate logistic regression analyses. The significance of any relationship between the MRI results and co-morbidities was tested using chi-squared tests.Results:Cerebral dysplasia, cerebroventricular enlargement, periventricular leukomalacia (PVL), abnormal signals in the thalami, and morphological changes after hypoxic ischemic encephalopathy were all found to be significantly correlated with GMFCS grading. Moreover, the chi-squared tests indicated that PVL children, children with thinning of the corpus callosum and/or abnormal signals in the thalami were significantly more likely to have visual, auditory or speech impairment complications and/or mental retardation.Conclusions:The findings from MRI correlate well with types of CP, GMFCS grades and co-morbidities among CP children. MRI can be an effective tool for early diagnosis and prognosis of CP in children, indicating needs for clinical rehabilitation.

ObjectiveTo explore the state of misdiagnosis, missed diagnosis and excesseive diagnosis related to cerebral palsy(CP).Methods389 cases were retrospectively analyzed who were misdiagnosed, missed or escessively diagnosed related to CP as the first diagnosis in the inpatient and outpatient department from July 1999 to March 2010.ResultsAmong 389 cases, 156 cases were missed or misdiagnosed as nutritional disease, and 118 cases of other diseases were misdiagnosed as CP, while 115 cases who were normal children was excessively diagnosed as CP. The false diagnosis had relativity with children's age: doctors are more prone to make misdiagonsis when the children's age are smaller, while 293 cases were misdiagnosed before 12 months old (75.3%); 102 cases (65.4%) were misdiagnosed or missed as other diseases before September, 2004, while 87 cases (75.7%) were excessively diagnosed as CP after September, 2004. Frequency of misdiagnosis as CP reduced from 2004, and the proportion dropped from 55.9% to 44.1%.ConclusionIt is very important to master the diagnostic standard of CP. Both sides of the question are important, one side is to make early diagnosis and early treatment in order to achieve the best effect of rehabilitation, and the other side is to prevent misdiagnosis and excessive diagnosis which woud delay illness, or waste medical resources, increase the financial and psychological burden.

ObjectiveTo investigate the effects of functional point injection on upper limbs disorder in cerebral palsy infants. Methods120 cases were divided into 2 groups and each with 60 cases. The treatment group was given rehabilitation and functional point injection (injecting VitB1>, VitB12 in the acu-points selected at the disorder muscles) and the control group was given rehabilitation alone. All the cases were assessed with Peabody Developmental Motor Scale Fine Motor (PDMS-FM) and Modified Ashworth Scale (MAS). ResultsThe scores of both PDMS-FM and MAS improved in the treatment group compared with the control group (P<0.05). ConclusionFunctional point injection can improve the recovery of upper limbs disorder in cerebral palsy infants.
