Objective To construct a radiomics model for predicting hematoma enlargement in early hypertensive intracerebral hemorrhage and explore its predictive value.Methods A retrospective collection of 212 patients with hypertensive intracerebral hemorrhage within 6 h of onset,admitted to our hospital from February 2010 to August 2018,was performed.CT examination was performed within half an hour of admission.CT re-examination was performed 24 h after admission to determine whether there was hematoma enlargement.The regions of interest were delineated on the first CT,and 431 image indicators were extracted from the Matlab software.The LASSO regression model was used to screen out the most predictive imaging features,and the selected features and support vector machine classifier (SVM) were used to build the prediction model.Receiver operating characteristic (ROC) curve was used to evaluate the predicted effect of the model.Results After 24 h of admission,the incidence of hematoma enlargement was 18.9％ (40/212).Eighteen imaging ensemble features (including 4 first-order statistics features:standard deviation,kurtosis,uniformity,and variance;one shape-and size-based feature:surface to volume ratio;7 textual features:long run low grey level emphasis,inertia,correlation-angle 90,short run emphasis,correlation-all direction,long run emphasis,and inverse difference moment;6 wavelet features:autocorrelation-3,informational measure of correlation2-3,long run high gray level emphasis-4,short run high gray level emphasis-4,short run low gray level emphasis-7,and sum variance-3) were combined with SVM to establish a prediction model by LASSO regression model.The area under ROC curve was 0.928,enjoying sensitivity and specificity of 92.5％ and 83.5％,respectively.Conclusion The constructed radiomics model is helpful in predicting the expansion of hypertensive cerebral hemorrhage.

Objective To explore the effect of cerebrospinal fluid release combined with controlled decompression under intracranial pressure monitoring on prevention of intraoperative intracranial swelling in patients with acute severe craniocerebral injury. Methods According to the inclusion and exclusion criteria, 90 patients with acute severe craniocerebral injury were randomly divided into study group (48 cases) and control group (42 cases). Patients in the study group underwent ventricular intracranial pressure probe placement, and then the standard decompressive craniectomy. During the operation, cerebrospinal fluid release combined with controlled decompression under intracranial pressure monitoring was applied to prevent brain swelling. Patients in the control group underwent standard decompressive craniectomy combined with controlled decompression to prevent brain swelling. The incidence of intraoperative brain swelling and cerebral infarction within 3 d after surgery, and the mortality within 1 month after surgery were evaluated. Prognosis was evaluated by GOS score after 3 months of follow-up. Results The brain swelling rate, cerebral infarction rate, mortality within 1 month, and Glasgow Coma Scale (GOS) score at 3 months after operation in the study group were better than those in the control group with statistical significance:10.4％(5/48) vs. 28.6％(12/42), 29.2％(14/48) vs. 64.3％(27/42), 18.8％(9/48) vs. 35.7％(15/42)], (2.83 ± 1.08) scores vs.(1.83 ± 0.76) scores, P<0.05. Conclusions Cerebrospinal fluid release combined with controlled decompression under intracranial pressure monitoring can reduce the incidence of intraoperative brain swelling and improve the prognosis of patients with acute severe craniocerebral injury.

Objective To compare the effects of urapidil and sodium nitroprusside on blood pressure and prognosis in patients with hypertensive intracerebral hemorrhage. Methods One hundred and fifty patients with hypertensive intracerebral hemorrhage from January to December 2017 were divided into urapidil group and sodium nitroprusside group according to the medication, each group with 75 patients. The changes of blood pressure, heart rate, hematoma size and neurological function were compared between the two groups. Results At 10 and 30 min after treatment, the systolic blood pressure and diastolic blood pressure of patients in urapidil group were lower than those in sodium nitroprusside group (P＜0.05). At 60 min after treatment , there was no significant difference on blood pressure between the two groups (P＞0.05). At 10, 30, 60, 120 and 240 min after treatment, the heart rate of patients in urapidil group were significantly lower than those in sodium nitroprusside group (P＜0.05). At 24 and 72 h after treatment, there was no notable difference in the size of hematoma between the two groups (P＞0.05). At 1 month after treatment, the neurological scores between the two groups were significantly different: (10.1 ± 2.1) scores vs. (13.8 ± 5.9) scores, P＜0.05. Conclusions Urapidil can effectively control blood pressure in patients with hypertensive intracerebral hemorrhage. Moreover, it exerts better long-term neuroprotective effect, compared with sodium nitroprusside.

ObjectiveTo study the effects of Toddalia asiatica alcohol extract on autophagy and apoptosis of non-small cell lung cancer A549 cells， and to explore its possible mechanism. MethodA549 cells were cultured in vitro. Cell counting kit-8 （CCK-8） was used to detect the proliferation of A549 cells， and cell survival rate was calculated to screen the drug concentration. The apoptosis in each dose group and that after the use of 3-methyladenine （3-MA）， an autophagy inhibitor， were detected by flow cytometry combined with Annexin V-FITC/PI double staining. Western blot was used to detect the expression levels of apoptosis-related proteins such as B cell lymphocytoma-2（Bcl-2）， Bcl-2-associated X protein（Bax）， microtubule-associated protein 1 light chain 3 （LC3）， cleaved cysteinyl aspartate-specific protease-3 （cleaved Caspase-3）， activated poly （Adenosine diphosphate） ribonucleotide polymerase （cleaved PARP1）， PARP1， activated death activator （t-Bid）， Bid， and ubiquitin-binding protein p62 in each group and those after the use of 3-MA. ResultCompared with the conditions in the control group， the cell survival rate in 0.25 g·L^-1 group （P<0.05）， and 0.5， 1， 2， 4 g·L^-1 groups （P<0.01） was decreased after 24 h intervention. Additionally， the cell survival rate was reduced in a concentration-dependent manner at 48 h and it was less than 10% at 4 g·L^-1 （P<0.01）. Compared with the conditions in the control group， the total apoptosis rate in 0.5 g·L^-1 group was increased （P<0.05）， and the apoptosis rate in 1 and 2 g·L^-1 groups was also increased （P<0.01）. Compared with the 2 g·L^-1 group and 3-MA group， the 3-MA combined with T. asiatica alcohol extract had significantly decreased apoptosis rate （P<0.01）. Compared with the conditions in the control group， elevated expression of pro-apoptotic proteins cleaved PARP1， Bax and t-Bid in 1 and 2 g·L^-1 groups （P<0.05， P<0.01）， and reduced expression of Bid in the 2 g·L^-1 group （P<0.01） were found. Compared with the conditions in the control group， the expression of anti-apoptotic protein Bcl-2 （P<0.05， P<0.01） and the level of p62 （P<0.01） were down-regulated in 0.5， 1， 2 g·L^-1 groups， while the level of LC3 Ⅱ protein was up-regulated （P<0.01）， with certain concentration dependence. ConclusionT. asiatica alcohol extract could significantly inhibit the proliferation of A549 cells， which might be related to promoting autophagy and inducing apoptosis.
