ABSTRACT
Objective:To discuss the regulatory effect of berberine(BBR)on fatty acids in the human glioma T98G cells and its effect on the cell proliferation,migration,and invasion,and to clarify its potential mechanism.Methods:The T98G cells at logarithmic growth phase were divided into control group and different concentrations(25,50,and 100 mg·L-1)of BBR groups.Cell wound healing assay was used to detect the migration rates of the cells in various groups;Transwell chamber assay was used to detect the invasion rates of the cells in various groups.The T98G cells at logarithmic growth phase were divided into control group and 100 mg·L-1 BBR group,and Mass spectrometry was used to detect the fatty acid contents in the cells in two groups.The T98G cells at logarithmic growth phase were divided into control group and different concentrations(50,100,and 150 mg·L-1)of BBR groups;Western blotting method was used to detect the expression levels of phosphatidylinositol 3-kinase(PI3K),phosphorylated PI3K(p-PI3K),protein kinase B(AKT),phosphorylated AKT(p-AKT),sterol regulatory element-binding protein 1(SREBP-1),and fatty acid synthase(FASN)in the cells in various groups.The expression of FASN was suppressed by gene silencing technology,and the T98G cells at logarithmic growth phase were divided into control group,shFASN1 group,and shFASN2 group.Western blotting method was used to detect the expression levels of FASN protein in the cells in various groups;clone formation assay was used to detect the clone formation of the cells in various groups;cell wound healing assay was used to detect the migration rates of the cells in various groups.Results:Compared with control group,the migration rates and invasion rates of the cells in different concentrations of BBR groups were decreased in a concentration-dependent manner(P<0.01),and the fatty acid content in the cells in 100 mg·L-1 BBR group was significantly decreased(P<0.01).Compared with control group,the expression levels of p-PI3K,p-AKT,SREBP-1,and FASN proteins in the cells in 150 mg·L-1 BBR group were significantly decreased(P<0.05 or P<0.01),and the expression level of SREBP-1 protein in the cells in 100 and 150 mg·L-1 BBR groups were significantly decreased(P<0.01).After suppression of FASN expression,compared with control group,the expression levels of FASN protein in the cells in shFASN1 and shFASN2 groups were significantly decreased(P<0.01),and the expression level of FASN protein in the cells in shFASN2 group was lower than that in shFASN1 group(P<0.05);compared with control group,the numbers of clone formation and migration rates of the cells in shFASN1 and shFASN2 groups were significantly decreased(P<0.01),and the migration rate of the cells in shFASN2 group was significantly lower than that in shFASN1 group(P<0.05).Conclusion:BBR interferes with fatty acid synthesis in the glioma T98G cells by reducing the expression of the PI3K/AKT/SREBP-1/FASN pathway related proteins,and decrease their migration and invasion capabilities.
ABSTRACT
Objective:To evaluate the efficacy of scalp nerve block combined with general anesthesia in optimizing anesthesia in the patients with moyamoya disease undergoing revascularization.Methods:A total of 154 patients with moyamoya disease, aged 18-64 yr, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, undergoing elective revascularization, were divided into 2 groups ( n=77 each) using a random nunber table method: scalp nerve block combined with general anesthesia group (GN group) and general anaesthesia group (G group). Anesthesia was induced with intravenous midazolam 0.05 mg/kg, sufentanil 0.5-1.0 μg/kg, rocuronium 0.6 mg/kg and etomidate 0.2-0.3 mg/kg.After the patients were tracheally intubated after anesthesia induction, ipsilateral scalp nerve block (2 ml for supraorbital nerve block, 2 ml for supratrochlear nerve block; 3 ml for auriculotemporal nerve block, 3 ml for greater occipital nerve block, 3 ml for less occipital nerve block) was performed with 0.5% ropivacaine in GN group.The equal volume of normal saline was locally injected in G group.Anesthesia was maintained by inhalation of sevoflurane and intravenous infusion of remifentanil 0.05-0.10 μg·kg -1·min -1 and cisatracurium 0.1 mg·kg -1·h -1.The consumption of intraoperative remifentanil, requirement for postoperative rescue analgesia, nausea and vomiting, length of postoperative hospital stay, and early neurological complications were recorded.The modified Rankin Scale scores were evaluated before operation, at discharge and at 6 months after operation. Results:Compared with G group, the consumption of intraoperative remifentanil and requirement for postoperative rescue analgesia were significantly decreased ( P<0.05), and no significant change was found in the incidence of postoperative nausea and vomiting, incidence of neurological complications, length of postoperative hospital stay, and modified Rankin Scale scores at each time point in GN group ( P>0.05). Conclusions:Scalp nerve block combined with general anesthesia can increase the perioperative analgesic efficacy and is helpful in achieving a low-opioid anesthesia mode when used in the patients with moyamoya disease undergoing revascularization.
ABSTRACT
Objective:To investigate the risk factors of proteinuria in patients with hypertension in Qinghai-Tibet Plateau.Methods:From March 2019 to June 2020, prospective design was used to collect data of Qinghai-Tibet Plateau hypertension patients who were eligible for continuous enrollment in the Department of Cardiovascular Medicine in Hospital of Chengdu Office of People's Government of Tibet Autonomous Region. Questionnaire survey, physical examination and blood pressure measurement were performed on the selected patients. Fasting venous blood samples were collected for liver function test, blood lipid test, blood glucose test, and hemoglobin test, etc. Three times of morning urine samples were taken on different days, and urine protein creatinine ratio (UACR) was measured, UACR < 30 mg/g was negative for urinary protein, and UACR≥30 mg/g was positive for urinary protein. At the same time, the selected patients were examined by carotid artery color ultrasound and heart color ultrasound. The risk factors of proteinuria were analyzed.Results:A total of 588 patients with hypertension met the inclusion criteria, including 472 patients (80.3%) who received antihypertensive drug therapy, 239 patients (40.6%) had antihypertensive treatment compliance, and 252 patients (42.9%) reached the standard blood pressure after theropy. Hypertension was associated with diabetes mellitus in 150 patients (25.5%), and urinary protein was positive in 126 patients (21.4%). In univariate analysis, ethnic composition, systolic blood pressure [(138.19 ± 19.65) vs (133.16 ± 18.45) mmHg, 1 mmHg = 0.133 kPa], diastolic blood pressure [(85.80 ± 13.51) vs (83.17 ± 12.19) mmHg], uric acid [(411.79 ± 101.54) vs (379.96 ± 102.18) μmol/L], hemoglobin [(152.86 ± 30.70) vs (143.49 ± 21.15) g/L], pulmonary artery trunk width [(21.76 ± 3.94) vs (20.98 ± 3.34) mm], and ventricular septal thickness [(9.90 ± 1.70) vs (9.47 ± 1.60) mm] in the positive group ( n = 126) were significantly higher than those in the negative group ( n = 462, P < 0.01 or < 0.05). In multivariate logistic regression analysis, increased systolic blood pressure [odds ratio ( OR) = 1.015, 95% confidence interval (95% CI): 1.005 - 1.026], uric acid ( OR = 1.003, 95% CI: 1.001 - 1.005), and pulmonary artery trunk width ( OR = 1.058, 95% CI: 1.001 - 1.118) were risk factors for proteinuria; Tibetans had a decreased risk of proteinuria compared with Han ( OR = 0.505, 95% CI: 0.317 - 0.805), but increased hemoglobin had an increased risk of proteinuria compared with normal hemoglobin ( OR = 1.890, 95% CI: 1.231 - 2.903). Conclusion:In patients with hypertension at high altitude, increased hemoglobin, systolic blood pressure, uric acid, pulmonary artery trunk width, and Han nationality are risk factors for proteinuria.
ABSTRACT
The clinical data of a case of paroxysmal extreme pain disorder(PEPD) in Guangdong 999 Brain Hospital were retrospectively analyzed.The male patient, age of first examination was 7 months, began to have recurrent tonic accompanied by facial redness or cyanosis at 5 months after birth.The patient was diagnosed with epilepsy.The oral solution of sodium valproate and Levetiracetam were not effective.The video electroencephalogram examination displayed that, when the patient had tonic and bradycardia, the synchro electroencephalogram did not show epileptic discharge, so the patient was considered to have non-epileptic tonic.Genetic examination suggested that SCN9A gene mutation of c. 5240T >C resulted in amino acid changes: Val1747Ala.Combined with the skin changes, the patient was diagnosed as PEPD caused by SCN9A gene mutation.After the treatment with Carbamazepine, the patient′s abnormal skin changed and his-epileptic tonic disappeared, and his condition improved significantly.The early stage of PEPD can be mainly manifested as non-epileptic tonic.It is easy to be misdiagnosed as epilepsy, so the patient′s characteristic skin changes should be noticed, and genetic examination is also helpful in the diagnosis of the disease.
ABSTRACT
Objective:To evaluate the efficacy and safety of fasudil on vasospasm caused by subarachnoid hemorrhage in elderly patients.Methods:A total of 100 elderly patients with subarachnoid hemorrhage admitted to our hospital from January 2015 to May 2018 were enrolled as research objects.They were randomly divided into the Fasudil group(n=50, receiving the Rho kinase inhibitor Fasudil therapy)and the Nimodipine group(n=50, receiving Nimodipine therapy). The cerebral vasospasm and cerebral infarction lesions, the ability of daily life, clinical prognostic score, the incidence of symptomatic cerebral vasospasm and adverse reactions during treatment were evaluated and compared between the two groups.Results:After treatment, the incidences of cerebral vasospasm and cerebral infarction in Fasudil group were 2.04%(1/49)and 6.12%(3/49), respectively, which were lower than those in the Nimodipine group[12.50%(6/48)and 20.83%(10/48), respectively]( χ2=6.134 and 6.794, P=0.047 and 0.033). The scores of daily living ability was better in the Fasudil group than in the Nimodipine group(16.09±1.06 vs.22.91±1.66, t=7.721, P=0.026). The incidence of adverse reactions was lower in the Fasudil group than in the Nimodipine group(4.08% or 2/49 vs.16.7% or 8/48, χ2=6.362, P=0.040). There was no statistically significant difference in the proportion of patients with good prognosis between Fasudil group and Nimodipine group. Conclusions:Rho kinase inhibitor Fasudil can effectively prevent and improve cerebral vasospasm caused by subarachnoid hemorrhage, which is beneficial for improving the clinical prognosis and quality of life of the elderly patients with subarachnoid hemorrhage.

MethodsOne hundred elder patients(60 ～ 85 years old), AS A class Ⅰ or Ⅱ, scheduled for selective surgeries,were divided equally into 5 different doses of propofol( constant intravenous injection for 1min) groups of 0.5mg/kg( Ⅰ ) ,0. 75mg/kg( Ⅱ ) ,1.0mg/kg(Ⅲ) ,1.25mg/kg( Ⅳ)and 1.5mg/kg(Ⅴ). HR,MAP,BIS and Narcotrend were monitored before propofol injection and at 1 and 5 min after propofol injection. ResultsHR of 5 group s as similar. At 1 min after pmpofol injection, MAP decreased remarkably compared with at before in all 5 groups( t =2. 17,2.84,2.49,5.63,7.10, all p ＜ 0.05 ), which in group Ⅳ and Ⅴ decreased significantly compared with at in group Ⅰ, Ⅱ and Ⅲ(t =4.67,2.77,2.45,5.49,4.57,2. 18,all P＜0.05).At 1 min after propofol injection,BIS and NI values decreased compared with at before in all 5 groups(t =7.74,11.74,28.18,30.34,45.28, 6. 65,10.52,17.27,26.28,30. 14,allP ＜0.05) ,which in groupⅢ, Ⅳ and Ⅴ were significantly lower than those in group Ⅰ and Ⅱ (t =12.59,11.08,16.72,15.12,17.67,15.64,allP＜0.05).Dose of propofol was negatively correlated with BIS and NI value ( r =-0. 898/0. 930, P ＜ 0.01 ). ConclusionPropofol 1.0mg/kg constant injection should meet the sedation and hypnosis demand of general anesthesia in elderly patients and could not inhibit circulatory system; Bispectral Index and Narcotrend could accuratly monitor depth of anesthesia in elderly patients.
