Objective To explore the efficacy and safety of low-dose tirofiban in stent-assisted coil embolization(SAC)for ruptured intracranial aneurysms.Methods From April 2011 to September 2020,335 patients of ruptured intracranial aneurysms with subarachnoid hemorrhage(SAH)admitted in the First People's Hospital of Changzhou were retrospectively analyzed.All cases underwent stent-assisted coil embolization within 24-48 h and antiplatelet medications.The patients were divided into dual antibody group(89 cases)and tirofiban group(246 cases).Baseline and clinical data of all patients were collected for comparison between groups,including age,sex,hypertension,diabetes mellitus,Hunt-Hess grade at admission,modified Fisher scale score at admission,aneurysm diameter(＞5 mm,≤5 mm),aneurysm location(anterior circulation,posterior circulation),postoperative acute hydrocephalus or intraventricular hemorrhage,postoperative complete embolization rate of ruptured aneurysm.All patients with ruptured intracranial aneurysm with SAH were confirmed by emergency cerebral CT scan after admission.The Raymond grading criteria were used to evaluate the embolization effect after operation:grade Ⅰ refers to no development(complete embolization),grade Ⅱ refers to only aneurysm neck development(incomplete embolization),and grade Ⅲ refers to aneurysm body development,in which Raymond grading Ⅰ orⅡ indicates effective embolization.Tirofiban group:4.2 μg/kg tirofiban was intravenously injected after the coil was placed in the aneurysm lumen and the stent was released,followed by maintenance dose 0.07 μg/(kg·min)for 6-8 h,and aspirin 100 mg and clopidogrel 75 mg were given as sequential dual antiplatelet therapy 2 hours before the tirofiban infusion was stopped.Dual antiplatelet group:a loading dose of aspirin 300 mg and clopidogrel 300 mg was given at least 2 hours before stent implantation,and then transferred to aspirin 100 mg and clopidogrel 75 mg given on the second day after operation.All patients received aspirin(100mg/d)for 6 months and clopidogrel(75 mg/d)for 3 months after operation.The efficacy indicators,safety indicators,adverse events and other complications of the two groups were collected and compared.The efficacy indicators were the incidence of thrombotic events during operation and within 72 hours after operation.The safety indicators were the incidence of intraoperative and early postoperative intracranial hemorrhage(within 48 hours after operation),the incidence of late postoperative intracranial hemorrhage(over 48 hours after operation),and the incidence of intracranial hemorrhage related to external ventricular drainage(symptomatic and asymptomatic).The adverse event was the occurrence of drug-related thrombocytopenia.Other complications were delayed ischemic events.The modified Rankin scale(mRS)score was used to evaluate the clinical prognosis of patients at 180 days after operation.mRS score ≤2 was defined as good prognosis,mRS score＞2 was defined as poor prognosis,of which 6 was defined as death.Results(1)There were no significant differences in baseline and clinical data between the tirofiban group and the dual antibody group(all P＞0.05).(2)There was no significant difference in the proportion of patients with good outcome(75.2％[185/246]vs.74.2％[66/89],P=0.845)and death(10.2％[25/246]vs.12.4％[11/89],P=0.566)at 180 days after operation between the tirofiban group and the dual antiplatelet group.(3)There was no significant difference in the incidence of intraoperative(0.8％[2/246]vs.4.5％[4/89],P=0.075)and postoperative thrombotic events(11.0％[27/246]vs.13.5％[12/89],P=0.527)between the tirofiban group and the dual antiplatelet group.(4)Results about safety comparison between this two antiplatelet regimens showed that the incidence of early postoperative intracranial hemorrhage were lower in the tirofiban group than that in the dual antiplatelet group(2.8％[7/246]vs.10.1％[9/89],P=0.014).There were no significant differences in the symptomatic external ventricular drainage related intracranial hemorrhage(0 vs.2/15,P=0.050),incidences of intraoperative intracranial hemorrhage(1.6％vs.3.4％,P=0.580),late postoperative intracranial hemorrhage(3.3％vs.4.5％,P=0.836),and drug-related thrombocytopenia(0.4％vs.1.1％,P=0.461)between the two groups.Conclusion Low-dose tirofiban infusion in SAC for ruptured aneurysms may prevent perioperative thromboembolic events without high risk of intracranial hemorrhage.

Background: and Purpose The relationships among interleukin (IL)-10 levels, anxiety, and cognitive status after stroke remain controversial. We aimed to determine the associations of serum IL-10 levels with poststroke anxiety (PSA) and poststroke cognitive impairment (PSCI). Methods: We recruited 350 patients with stroke, of whom only 151 completed a 1-month follow-up assessment. The Mini Mental State Examination (MMSE) and Hamilton Anxiety Scale (HAMA) were used to assess the cognitive status and anxiety, respectively. Serum IL-10 levels were measured within 24 hours of admission. Results: IL-10 levels were significantly lower in the PSA group than in the non-PSA group, and they were negatively associated with HAMA scores (r=-0.371, p<0.001). After adjusting for all potential confounders, IL-10 levels remained an independent predictor of PSA (odds ratio=0.471, 95% confidence interval=0.237–0.936, p=0.032). IL-10 levels were strongly correlated with behavior during interviews, psychic anxiety, and somatic anxiety. Patients without PSCI had higher IL-10 levels were higher in non-PSCI patients than in PSCI patients, and they were positively associated with MMSE scores in the bivariate correlation analysis (r=0.169, p=0.038), and also with memory capacity, naming ability, and copying capacity.However, IL-10 did not predict PSCI in the univariable or multivariable logistic regression. Conclusions Low IL-10 levels were associated with increased risks of PSA and PSCI at a 1-month follow-up after stroke. Serum IL-10 levels may therefore be helpful in predicting PSA.

Objective: To investigate the prognostic factors of children with congenital heart disease (CHD) who had undergone cardiopulmonary resuscitation (CPR) in pediatric intensive care unit (PICU) in China. Methods: From November 2017 to October 2018, this retrospective multi-center study was conducted in 11 hospitals in China. It contained data from 281 cases who had undergone CPR and all of the subjects were divided into CHD group and non-CHD group. The general condition, duration of CPR, epinephrine doses during resuscitation, recovery of spontaneous circulation (ROSC), discharge survival rate and pediatric cerebral performance category in viable children at discharge were compared. According to whether malignant arrhythmia is the direct cause of cardiopulmonary arrest or not, children in CHD and non-CHD groups were divided into 2 subgroups: arrhythmia and non-arrhythmia, and the ROSC and survival rate to discharge were compared. Data in both groups were analyzed by t-test, chi-square analysis or ANOVA, and logistic regression were used to analyze the prognostic factors for ROSC and survival to discharge after cardiac arrest (CA). Results: The incidence of CA in PICU was 3.2% (372/11 588), and the implementation rate of CPR was 75.5% (281/372). There were 144 males and 137 females with median age of 32.8 (5.6, 42.7) months in all 281 CPA cases who received CPR. CHD group had 56 cases while non-CHD had 225 cases, with the percentage of 19.9% (56/281) and 80.1% (225/281) respectively. The proportion of female in CHD group was 60.7% (34/56) which was higher than that in non-CHD group (45.8%, 103/225) (χ²=4.00, P=0.045). There were no differences in ROSC and rate of survival to discharge between the two groups (P>0.05). The ROSC rate of children with arthythmid in CHD group was 70.0% (28/40), higher than 6/16 for non-arrhythmic children (χ²=5.06, P=0.024). At discharge, the pediatric cerebral performance category scores (1-3 scores) of CHD and non-CHD child were 50.9% (26/51) and 44.9% (92/205) respectively. Logistic regression analysis indicated that the independent prognostic factors of ROSC and survival to discharge in children with CHD were CPR duration (odds ratio (OR)=0.95, 0.97; 95%CI: 0.92~0.97, 0.95~0.99; both P<0.05) and epinephrine dosage (OR=0.87 and 0.79, 95%CI: 0.76-1.00 and 0.69-0.89, respectively; both P<0.05). Conclusions: There is no difference between CHD and non-CHD children in ROSC and survival rate of survival to discharge was low. The epinephrine dosage and the duration of CPR are related to the ROSC and survival to discharge of children with CHD.

OBJECTIVE: To analyze the preservation effect and related influencing factors of human peripheral blood mononuclear cells under serum-free condition at 4 ℃. METHODS: Human peripheral blood mononuclear cells were isolated by density gradient centrifugation, and stored at 4 ℃ under different cell concentrations, supplemented with human serum albumin, and glucose. The cell viability, total cell number, viable cell number and cell phenotype were detected during preservation of 72 h. RESULTS: With the prolongation of storage time, the number of human peripheral blood mononuclear cells gradually decreased(r=0.982). Compared with the cell concentration of (5-6)×10⁶ cells/ml, the cell number decreased more slowly when the cell storage concentration was (1-2)×10⁶ cells/ml; Adding human serum albumin and glucose can effectively improve the survival rate of human peripheral blood mononuclear cells, among which 2% human serum albumin has a better preservation effect; Compared with the blank control group, the analysis results of cell subsets showed that the downward trends of NK cells and T cells were significantly slowed after adding albumin and glucose. CONCLUSION The cell density of (1-2)×10⁶/ml and 2% human serum albumin are more suitable for the preservation of PBMC, and 5% glucose can improve the preservation effect of human peripheral blood mononuclear cells at 4 ℃.

Whether in the West or the East, the connection between the ear and the rest of the body has been explored for a long time. Especially in the past century or more, the relevant theoretical and applied research on the ear has greatly promoted the development of ear therapy, and finally the concept of transcutaneous auricular vagus nerve stimulation (taVNS) has been proposed. The purpose of taVNS is to treat a disease non-invasively by applying electrical current to the cutaneous receptive field formed by the auricular branch of the vagus nerve in the outer ear. In the past two decades, taVNS has been a topic of basic, clinical, and transformation research. It has been applied as an alternative to drug treatment for a variety of diseases. Based on the rapid understanding of the application of taVNS to human health and disease, some limitations in the development of this field have also been gradually exposed. Here, we comprehensively review the origin and research status of the field.

Objective: To investigate the impact of obstructive sleep apnea (OSA) on long-term cardiovascular outcomes in patients with acute coronary syndrome (ACS). Methods: This is a single-center, prospective cohort study. Between June 2015 to January 2020, consecutive ACS patients hospitalized at Beijing Anzhen Hospital, Capital Medical University were enrolled. All patients underwent portable sleep breathing monitoring, and they were then divided into moderate/severe OSA group (apnea-hypopnea index (AHI)≥15 events/hour) and no/mild OSA group (AHI<15 events/hour). The primary endpoint was major adverse cardiac and cerebrovascular event (MACCE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, ischemia-driven revascularization and hospital admission for unstable angina or heart failure. MACCE were compared yearly by the log-rank test. Multivariable Cox regression analyses were performed to determine the independent predictors of MACCE. Results: A total of 1 927 patients with ACS were enrolled, including 1 629 males (84.5%), aged (56.4±10.5) years. Moderate/severe OSA was present in 1 014 (52.6%) patients. Compared with no/mild OSA group, moderate/severe OSA group exhibited a higher body mass index (P<0.05). Hypertension, prior PCI were more prevalent in moderate/severe OSA group (both P<0.05). The difference of ACS category between the two groups was statistically significant (P=0.021). The rate of patients who underwent PCI and the number of stents were higher in the moderate/severe OSA group. During a 5-year follow-up (median 2.9 years (IQR 1.5-3.6 years)), the cumulative incidence of MACCE was significantly higher in the moderate/severe OSA group than in the no/mild OSA group (34.0% vs. 24.0%, HR=1.346, 95%CI 1.100-1.646, log-rank P=0.004). The cumulative incidence of MACCE remained statistically higher at 4 and 5 year in the moderate/severe OSA group as compared to the no/mild OSA group (33.3% vs. 22.9%, HR=1.397, 95%CI 1.141-1.710, log-rank P=0.001; 34.0% vs. 24.0%, HR=1.341, 95%CI 1.096-1.640, log-rank P=0.004, respectively). Multivariate analysis showed that moderate/severe OSA (HR=1.312, 95%CI 1.054-1.631, P=0.015) was an independent predictor of long-term MACCE in ACS patients. Conclusions: Moderate/severe OSA is observed in more than 52% ACS patients. Moderate/severe OSA is an independent predictor of long-term MACCE.

OBJECTIVE: To observe the effect of acupuncture at "Baihui" (GV 20), "Zhongwan" (CV 12) and "Zusanli" (ST 36) on intestinal flora in rats with stress gastric ulcer (SGU) , and to explore the mechanism of acupuncture promoting SGU recovery. METHODS: Thirty-one SPF SD rats were randomly divided into a control group (7 rats), a model control group (8 rats), an acupuncture group (8 rats) and a medication group (8 rats). The rats in the model group, acupuncture group and medication group were selected to applied the improved restraint water-immersion stress method to establish the SGU model. After modeling, the rats in the control group and model group were fixed and restrained for 20 min every day for a total of 5 days; the rats in the acupuncture group were intervented with acupuncture at "Baihui" (GV 20), "Zhongwan" (CV 12) and "Zusanli" (ST 36), once a day, 20 min each time, and twisting needle for 30 s every 5 min for a total of 5 days; the rats in the medication group were gavaged by solution of omeprazole enteric-coated tablet (200 mg/mL), 2 mL for each rat, once a day. Guth method was used to calculate the gastric mucosal damage index (GMDI), HE staining was used to observe the pathological changes of gastric mucosa, and 16SrDNA identification was used to detect the structural abundance of intestinal flora. RESULTS: Compared with the control group, the GMDI of rats in the model group was increased (<0.01), the gastric mucosal pathological changes were significant, and the intestinal flora richness index Chao1, Observed species and diversity index Shannon were all decreased (<0.05), the diversity index Simpson was increased (<0.05). Compared with the model group, the GMDI of rats in the acupuncture group and medication group was reduced (<0.01, <0.05), the gastric mucosal damage degree was reduced, and the intestinal flora richness index Chao1, Observed species and diversity index Shannon were all increased (<0.05) and the diversity index Simpson decreased (<0.05). Compared with the medication group, the GMDI of rats in the acupuncture group was reduced (<0.01), the recovery of gastric mucosal injury was better than that of the medication group. CONCLUSION Acupuncture can effectively improve gastric mucosal injury of SGU, and the mechanism may be related to increasing the diversity of intestinal flora and promoting the correction of the disordered intestinal flora.

Objective::To investigate the regulatory effect of Danggui Shaoyaosan (DSS)-containing serum on oxidative stress and inflammation in H₂O₂-induced SH-SY5Y cells. Method::Methyl thiazolyl tetrazolium(MTT) assay was used to determine the cell activity and construct the H₂O₂-induced cell damage model with the optimal time and dose. Normal group, model group and high, medium and low-dose DSS groups(2.5%, 5%, 10%) were set up. MTT method was used to detect cell activity, spectrophotometry anti-oxidation indexes of malonaldehyde (MDA), catalase (CAT) and superoxide dismutase (SOD) and glutathione (GSH). Real-time quantitative PCR (Real-time PCR) was used to detect tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) mRNA expressions. And immunofluorescence test was adopted to detect nuclear transcription factor-κB(NF-κB) p65 nuclear translocation of the DSS after the intervention. Result::After 24 h intervention with 250 μmol·L^-1 H₂O₂, SH-SY5Y cell viability was about 55%, which was the best modeling condition. After high, medium and low-dose DSS intervention on H₂O₂-damaged cell model, compared with the model group, the cell activity showed a dose-dependent increase (P<0.05), MDA was significantly reduced (P<0.05), and antioxidant indexes CAT, SOD and GSH were significantly increased (P<0.05). H₂O₂ could significantly increase SH-SY5Y cell inflammatory factor TNF-α, IL-6 and IL-1β mRNA expressions, and promote activation of cytoplasmic NF-κB and nuclear translocation. DSS-containing serum showed a dose-dependent inhibition of NF-κB p65 from nuclear, and reduced inflammatory factor levels, such as TNF-α, IL-6 and IL-1β. Conclusion::DSS-containing serum can significantly reduce the oxidative damage in H₂O₂-induced SH-SY5Y cells by improving their antioxidant status, and reduce the inflammatory response by inhibiting NF-κB signaling pathway.
