ABSTRACT
BACKGROUND@#The mortality rate of lung cancer meningeal metastasis is extremely high. Circulating tumor DNA (ctDNA) has been confirmed to be contain the genomic alterations present in tumors and has been used to monitor tumor progression and response to treatments. Due to the presence of blood-brain barrier and other factors, peripheral blood ctDNA cannot reflect the information of brain lesions for patients with meningeal metastases. However, cerebrospinal fluid ctDNA as a test sample can better reflect the genetic status of intracranial tumors and guide clinical targeted treatment of intracranial lesions. This study explored the feasibility of cerebrospinal fluid ctNDA for evaluating non-small cell lung cancer (NSCLC) meningeal metastasis and the potential clinical value of cerebrospinal fluid ctDNA detection in NSCLC meningeal metastasis.@*METHODS@#A total of 21 patients with NSCLC meningeal metastasis were included. Tumor genomic variation was performed on the cerebrospinal fluid and peripheral blood samples of patients by second-generation gene sequencing technology. The situation was examined, and pathological evaluation of cerebrospinal fluid cytology and head magnetic resonance imaging (MRI) enhanced examination were performed.@*RESULTS@#ctDNA was detected in the cerebrospinal fluid of 21 patients. The sensitivity of cerebrospinal fluid ctDNA detection was superior to cytology in the diagnosis of meningeal metastasis (P<0.001). The detection rate and gene mutation abundance of cerebrospinal fluid were higher than plasma (P<0.001). Cerebro-spinal fluid had a unique genetic profile. In 6 patients with dynamic detection, changes of ctDNA allele fraction occurred at the same time or earlier than clinical disease changes, which could timely monitor drug resistance mechanism and relapse trend.@*CONCLUSIONS@#The detection rate of ctDNA in cerebrospinal fluid is higher than that in cytology and imaging. The detection of ctDNA in cerebrospinal fluid can reveal the specific mutation map of meningeal metastasis lesions. The dynamic monitoring of ctDNA in cerebrospinal fluid has hint significance for clinical response of lung cancer patients.
ABSTRACT
To discuss therapeutic effect of intravenous drip of monosialic tetrahexose ganglioside (MTG) combined comprehensive rehabilitation on patients with stroke hemiplegia and its impact on neurologic impairment score (NIS).Methods : A total of 100 patients with stroke hemiplegia treated in our hospital were randomly and e‐qually divided into routine treatment group (received routine comprehensive training treatment including work ther‐apy ,exercise therapy etc .) and combined treatment group (received intravenous drip of MTG based on routine treatment group) ,both groups were continuously treated for four weeks .Limb and neurologic function ,and im‐provement of quality of life (QOL) were compared between two groups .Results : Oneight weeks after treatment , total effective rate of limb function in combined treatment group was significantly higher than that of routine treat‐ment group (94. 0% vs.76. 0%, P＝0.030) ;after one ,four and eight‐week treatment ,along with time went on , there was significant rise in Glasgow coma scale (GCS) score in two groups ,and those of combined treatment group were significantly higher than those of routine treatment group [one week :(8. 56 ± 2. 47) scores vs .(7.24 ± 2.01) scores ,four weeks :(11.26 ± 2.81) scores vs .(9.23 ± 2. 01) scores ,eight weeks :(13.28 ± 3.43) scores vs .(11. 43 ± 2.65) scores] , P＜0. 01 all ;compared with before treatment ,there were significant rise in each dimension score of QOL in two groups after eight‐week treatment ,and each dimension score of combined treatment group was sig‐nificantly higher than that of routine treatment group , P＝0. 001 all.Conclusion : Intravenous drip of MTG com‐bined comprehensive rehabilitation possesses significant therapeutic effect on patients with stroke hemiplegia .It can significantly improve limb and neurologic function state ,improve quality of life in these patients .
ABSTRACT
Objective To study relationship between length of sterna-pubis line, cervical vertebrae-coc-cyx line and stature in West of Hubei Province. Methods 400 men and women were randomly chosen. Length of sterna-pubis line, length of cervical vertebrae-coccyx line and stature in every person were mea-sured, and all data analysesd by multiple linear regression analysis. Results we have estiblished Eight quadratic equation which stature was calculated via different sex and age groups. Significant difference was observed between the length of sterna-pubis line, and cervical vertebrae-coccyx line and the stature in age group of 18-40. Yet nosignificant difference was seen over 41 and this method must be used with care. Conclusion These equations can be used to determine the stature of Chinese adults.
