Objective The aim of the study was to investigate the related factor of postoperative provisional paraly?sis of parasagittal meningioma in the eloquent area. Methods A retrospective review was conducted on ninety-six pa?tients with parasagittal meningioma in the eloquent area treated by surgery from May 2005 to December 2015. Accord?ing to the diagnostic criteria for postoperative provisional paralysis, patients were divided into postoperative provisional paralysis group(n=31)and non- postoperative provisional paralysis group(n=65). Univariate and multivariate logistic regression methods were used to analyze the data including age, size of tumor,preoperative epilepsy, preoperative periph?eral edema, complete the occlusion of superior sagittal sinus(SSS) by tumor, incision of SSS during surgery, drainage vein damage during surgery. Results Univariate analysis showed that there were significant differences(P<0.05)between these two groups in age(χ2=14.943,P=0.000), preoperative peripheral edema(χ2=4.435,P=0.049), the complete occlu?sion of SSS by tumor(χ2=5.248,P=0.028), incision of SSS during surgery(χ2=5.773,P=0.026), drainage vein damage during surgery(χ2=11.441,P=0.002). Multivariate analysis showed that the factors related to postoperative provisional paralysis were age(OR=8.709,P=0.028), drainage vein damage during surgery(OR=16.242,P=0.012)and complete oc?clusion of SSS by tumor(OR=0.053,P=0.025). Conclusion Age and the drainage vein damage during surgery are the risk factors of postoperative provisional paralysis and complete occlusion of SSS by tumor is the protective factor for the oc? currence of postoperative provisional paralysis.

Abnormal tumour cell adhesion is a key step in tumour metastasis, in which weakened homologous and enhanced heterologous adhesion of tumour cells is an important cause of tumour metastasis. Chronic stress can activate the sympathetic nervous system to link and regulate the homologous and heterologous adhesion of tumour cells and exacerbate tumour metastasis. Combining the understanding of traditional Chinese medicine (TCM) and Western medicine on tumour metastasis, it is believed that the mechanism of "qi constraint and stagnation, tumor toxin transmission and retention" in TCM theory is highly related to the abnormal adhesion of tumour cells triggered by chronic stress. Qi constraint and stagnation is closely related to chronic stress and its activation of the sympathetic nervous system, and transmission and retention of tumor toxin explained the mechanism of tumour metastasis due to abnormal adhesion of tumour cells from the perspective of TCM. By regulating the key link of sympathetic nervous system-tumour cell adhesion, application of the formulas of regulating qi and resolving toxin can improve chronic stress and inhibit tumour metastasis.

OBJECTIVE:
To investigate the effects of restrictive fluid management in patients with severe traumatic brain injury (sTBI).
METHODS:
Between January, 2019 and June, 2020, we randomly assigned 51 postoperative patients (stay in the ICU of no less than 7 days) with sTBI into treatment group (
RESULTS:
The cumulative fluid balance of the two groups were positive on day 1 and negative on days 3 and 7 after ICU admission; at the same time points, the patients in the treatment group had significantly greater negative fluid balance than those in the control group (
CONCLUSIONS
Restrictive fluid management can reduce cerebral edema and improve the prognosis but does not affect the 28-day mortality of patients with sTBI.
