RESUMEN
Objective:To investigate the significance of ventricular intracranial pressure monitoring in the treatment of traumatic multiple intracranial hematoma (TMIH).Methods:The clinical data of 14 TMIH patients treated with ventricular intracranial pressure monitoring from January 2016 to August 2021 in Beijing Luhe Hospital, Capital Medical University were analyzed retrospectively. The patients were followed up 6 months after injury, and the Glasgow outcome score (GOS) was assessed.Results:All the 14 patients successfully completed ventricular intracranial pressure probe placement. Among them, 8 patients recovered well after continuous monitoring of ventricular intracranial pressure and continuous cerebrospinal fluid drainage. Their ventricular intracranial pressure probe was placed for 5 to 10 (7.3 ± 2.2) d, with no intracranial infection occurred; and their GOS was 5 scores 6-month follow-up after injury. Six cases underwent craniotomy for hematoma removal due to the expansion of intracranial hematoma or aggravation of edema, and decompressive craniectomy was performed during the operation; 6-month follow-up after injury, GOS of 5 scores was in 3 cases, 4 scores in 2 cases, 3 scores in 1 case.Conclusions:The condition of TMIH patients is complex and changeable, and ventricular intracranial pressure monitoring can improve the prognosis of TMIH patients.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.

Methods The clinical data of 16 patients with large olfactory groove meningiomas who had underwent microsurgical treatment by unilateral subfrontal approach from January 2010 to December 2017 were analyzed retrospectively. Results Total removal of tumor (Simpson Ⅰ and Ⅱ grade) was achieved in 14 cases and subtotal removal of the tumor (Simpson Ⅲ) was in 2 cases. No patient died from the microsurgery. The treatment effect was satisfactory in all patients during the follow- up. Conclusions The microsurgical treatment by unilateral subfrontal approach in patients with large olfactory groove meningiomas conforms to the concept of minimal invasive surgery, which provides enough surgical space, and the effect of surgery is satisfactory. So the approach is a good choice for the removal of large olfactory groove meningiomas.

Objective To explore the application value of percutaneous dilational tracheostomy in the neurological intensive patients. Methods The clinical data of 298 neurological intensive patients treated with percutaneous dilational tracheotomy were analyzed retrospectively from June 2010 to July 2016. Results Percutaneous dilational tracheostomy was successfully performed in all of the 298 cases. The mean operation duration was (6.8 ± 2.2) minutes with a rang of 2 to 15 min. There were 1 case with tracheal tube placement difficulties, 1 case in whom the trachea spatium was strayed into, 1 case with arrhythmia, 10 cases with mild bleeding and 5 cases with moderate bleeding. No severe bleeding, subcutaneous emphysema, pneumothorax, tracheoesophageal fistula and other complications caused by the operation were found. And no death case was found. Conclusions Percutaneous dilational tracheostomy is a rapid and minimally invasive technique, which is a better choice for patients with severe neurological diseases.
