Objective To investigate the effects of different ventilation strategies on intraocular pressure (IOP) and intracranial pressure in patients undergoing spinal surgery in the prone position under general anesthesia. Methods Seventy-two patients undergoing prone spinal surgery under general anesthesia between November, 2022 and June, 2023 were equally randomized into two groups to receive routine ventilation (with Vt of 8mL/kg, Fr of 12-15/min, and etCO2 maintained at 35-40 mmHg) or small tidal volume hyperventilation (Vt of 6 mL/kg, Fr of18-20/min, and etCO2 maintained at 30-35 mmHg) during the surgery. IOP of both eyes (measured with a handheld tonometer), optic nerve sheath diameter (ONSD;measured at 3 mm behind the eyeball with bedside real-time ultrasound), circulatory and respiratory parameters of the patients were recorded before anesthesia (T0), immediately after anesthesia induction (T1), immediately after prone positioning (T2), at 2 h during operation (T3), immediately after supine positioning after surgery (T4) and 30 min after the operation (T5). Results Compared with those at T1, IOP and ONSD in both groups increased significantly at T3 and T4 (P<0.05). IOP was significantly lower in hyperventilation group than in routine ventilation group at T3 and T4 (P<0.05), and ONSD was significantly lower in hyperventilation group at T4 (P<0.05). IOP was positively correlated with the length of operative time (r=0.779, P<0.001) and inversely with intraoperative etCO2 at T3 (r=-0.248, P<0.001) and T4 (r=-0.251, P<0.001). ONSD was correlated only with operation time (r=0.561, P<0.05) and not with IOP (r=0.178, P>0.05 at T3;r=0.165, P>0.05 at T4). Conclusion Small tidal volume hyperventilation can relieve the increase of IOP and ONSD during prone spinal surgery under general anesthesia.

Objective To analyze the relationship between plasma mitochondrial DNA(mtDNA),macrophage inflammatory protein-1α(MIP1α)and monocyte chemotactic protein 1(MCP-1)in vastus lateralis tissues and postoperative muscle atrophy,recovery of hip function in patients with hip fractures.Methods A total of 86 patients with hip fractures and 43 patients with coxitis in Jinan Eighth People's Hospital were enrolled as hip fracture group and coxitis group between October 2020 and October 2022,respectively.The lateral muscle tissues were collected as samples during surgery.The level of plasma mtDNA was detected by real-time fluorescence quantitative polymerase chain reaction.Before surgery,levels of serum interleukin-6(IL-6)and tumor necrosis factor α(TNF-α)were detected by enzyme-linked immunosorbent assay.Before surgery,cross-sectional areas of types Ⅰ and Ⅱ vastus lateralis fibers were detected by immunofluorescence method.Before surgery,expression levels of MIP1α and MCP-1 proteins in lateral muscle tissues were detected by Western blot.All patients with hip fracture were effectively followed up for 6 months after surgery.At 3 and 6 months after surgery,total lean mass(TLM)and unaffected limb lean mass(ULLM)were detected by DXA.Results The level of plasma mtDNA in hip fracture group was higher than that in coxitis group before surgery[(4.12±0.53)vs(2.37±0.36),P＜0.05],levels of serum IL-6 and TNF-α were higher than those in coxitis group[(34.68±6.14)pg/ml,(21.54±4.12)pg/ml vs(12.74±3.06)pg/ml,(10.81±2.71)pg/ml,P＜0.05],cross-sectional areas of types Ⅰ and Ⅱ vastus lateralis fibers were smaller than those in coxitis group[(4321.45±441.36)μm2,(2384.38±247.11)μm2 vs(5417.63±553.27)μm2,(3569.24±368.22)μm2,P＜0.05],and expression levels of MIP1α and MCP-1 proteins were higher than those in coxitis group[(2.34±0.25),(2.47±0.28)vs(1.18±0.15),(1.95±0.23),P＜0.05].In patients with hip fracture after 6 months of follow-up,there were 53 cases with good prognosis and 33 cases with poor prognosis.The level of plasma mtDNA in poor prognosis group was higher than that in good prognosis group before surgery[(4.53±0.52)vs(3.87±0.44),P＜0.05],levels of serum IL-6 and TNF-α were higher than those in good prognosis group[(35.97±5.32)pg/ml,(20.74±4.27)pg/ml vs(33.51±5.16)pg/ml,(22.83±4.33)pg/ml,P＜0.05],cross-sectional areas of types Ⅰ and Ⅱ vastus lateralis fibers were smaller than those in good prognosis group[(4174.26±434.60)μm2,(2309.56±246.18)μm2 vs(4394.42±450.12)μm2,(2430.97±250.72)μm2,P＜0.05],and expression levels of MIP1α and MCP-1 proteins were higher than those in good prognosis group[(2.47±0.28),(1.95±0.23)vs(2.26±0.24),(1.82±0.21),P＜0.05].TLM and ULLM at 6 months after surgery were lower than those at 3 months after surgery in good prognosis group and poor prognosis group(P＜0.05).At 3 and 6 months after surgery,there was no significant different in TLM or ULLM between good prognosis group and poor prognosis group(P＞0.05).Conclusion Traumatic stress injury will increase level of plasma mtDNA in patients with hip fracture,which will induce the increase of systemic inflammatory indexes(serum IL-6,TNF-α)and inflammatory factors(MCP-1,MIP1α)levels,aggravate muscle atrophy and cause postoperative decline of hip function.

In this study, we presented the isolation and characterization of eight novel seco-guaianolide sesquiterpenoids (1-8) and two known guaianolide derivatives (9 and 10), from the aerial part of Achillea alpina L.. Compounds 1-3 were identified as guaianolides bearing an oxygen insertion at the 2, 3 position, while compounds 4-8 belonged to a group of special 3-nor guaianolide sesquiterpenoids. The structural elucidation of 1-8, including their absolute configurations, were accomplished by a combination of spectroscopic data analysis and quantum electronic circular dichroism (ECD) calculations. To evaluate the potential antidiabetic activity of compounds 1-10, we investigated their effects on glucose consumption in palmitic acid (PA)-mediated HepG2-insulin resistance (IR) cells. Among the tested compounds, compound 7 demonstrated the most pronounced ability to reverse IR. Moreover, a mechanistic investigation revealed that compound 7 exerted its antidiabetic effect by reducing the production of the pro-inflammatory cytokine IL-1β, which was achieved through the suppression of the NLRP3 pathway.

Objective:To comprehensively evaluate the correlation between migraine and the risk of hemorrhagic stroke using Meta-analysis.Methods:The published observational studies on migraine and the risk of hemorrhagic stroke in PubMed, EMbase, Cochrane library, Chinese Biomedical Database, China Journal Full-text Database, Wanfang Database and VIP Database were retrieved by computers. The retrieval time limit was from the establishment of the databases to December 31, 2019. Two reviewers independently conducted the literature screening and data extraction, and evaluated the quality according to Newcastle Ottawa scale. Stata SE 12.1 software was used for Meta-analysis.Results:Six case-control studies and 7 cohort studies met the inclusion criteria, all of which were in English. The results of Meta-analysis showed that exposure to migraine increased the risk of hemorrhagic stroke (odds ratio [ OR] 1.47, 95% confidence interval [ CI] 1.23-1.76; P<0.001). Sensitivity analysis showed that the results were robust. Subgroup analysis showed that migraine with aura ( OR 1.38, 95% CI 1.05-1.81; P=0.019), migraine without aura ( OR 1.46, 95% CI 1.19-1.80; P<0.001), male ( OR 2.10, 95% CI 1.72-2.56; P<0.001) and female ( OR 1.53, 95% CI 1.22-1.92; P<0.001) migraine could increase the risk of hemorrhagic stroke. Conclusion:Regardless of the gender of patients and presence or absence of migraine aura, migraine can significantly increase the risk of hemorrhagic stroke.

Objective: By detecting the expression of interleukin-13 (IL-13) and periostin in the airway of asthmatic patients, the pathological changes and pulmonary functions of airway tissues in asthmatic patients were evaluated, and the role of IL-13 and periostin airway remodeling in bronchial asthma was preliminarily explored. Methods: The bronchial tissues adjacent to tumor nest were obtained from 12 patients with lung cancer complicated with bronchial asthma (asthmatic group) and 12 lung cancer patients without bronchial asthma (non-asthmatic group) after lung cancer resection. Pulmonary function was measured for all subjects before surgery. Pathological changes of airway tissues and degree of airway remodeling were assessed by hematoxylin-eosin (H&E) staining, masson′s trichrome staining, and periodic acid-silver methenamine (PASM) staining of paraffin-embedded sections. The expression of IL-13 and periostin in bronchial tissues were evaluated by immunohistochemistry. Results: Values of the forced expiratory volume in 1 second of the predicted value (FEV1% pred) and FEV1/forced vital capacity (FEV1/FVC%) in asthmatic patients were significantly decreased compared with the non-asthmatic patients (P<0.05), indicating that lung function was impaired in asthmatic patients. There was more severe airway remodeling representing as thickening of basement membranes, collagen deposition, and increasing of goblet cells and fibroblasts in asthmatic patients than in non-asthmatic patients (all P<0.05). The expression of IL-13 and periostin were higher in asthmatic tissues than in non-asthmatic tissues (P<0.05). The immunohistochemical expression of IL-13 and periostin in bronchial tissues were positively correlated with the degree of airway remodeling in asthmatic patients, and the expression of IL-13 and periostin in bronchial tissues were positively correlated with each other. Conclusions The expression of IL-13 and periostin were increased in bronchial tissue in patients with asthma. They work together to promote the occurrence of airway remodeling, which eventually lead to a decline in lung function.

OBJECTIVE: The aims of the present study were to explore the occurrence of childhood trauma and importantly to determine the impacts of childhood trauma on psychosocial features in a Chinese sample of young adults. METHODS: A survey was carried out in a group of 555 university students by using Childhood Trauma Questionnaire (CTQ), Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS), Dysfunctional Attitudes Questionnaire (DAS), Eysenck Personality Questionnaire (EPQ), and Social Support Rating Scale (SSRS). The moderate-severe cut-off scores for CTQ were used to calculate the prevalence of childhood trauma, and then psychosocial features were compared between individuals with and without childhood trauma. RESULTS: A proportion of 18.6% of university students had self-reported childhood trauma exposures. Subjects with childhood trauma reported higher scores of SDS, SAS, DAS, and psychoticism and neuroticism dimensions of EPQ (t=4.311–5.551, p < 0.001); while lower scores of SSRS and extraversion dimension of EPQ (t=-4.061– -3.039, p < 0.01). Regression analyses further revealed that scores of SAS and DAS were positively (Adjusted B=0.211–0.230, p < 0.05), while scores of SSRS were negatively (Adjusted B=-0.273– -0.240, p < 0.05) associated with specific CTQ scores. CONCLUSION: Childhood trauma is still a common social and psychological problem. Individuals with childhood trauma show much more depression, anxiety, distorted cognition, personality deficits, and lower levels of social support, which may represent the social and psychological vulnerability for developing psychiatric disorders after childhood trauma experiences.

Objective To investigate the predictive value of neutrophil to lymphocyte ratio (NLR) in peripheral blood for the outcomes in patients with acute intracerebral hemorrhage.Methods Consecutive inpatients with intracerebral hemorrhage diagnosed with the head CT were entolled.The modified Rankin Scale (mRS) was used to evaluate the functional outcomes at 90 d,0-2 wvas defined as good outcome,3-6 were defined as poor outcome,and 6 was defined as death.Univariate analysis was used to compare the demographic characteristics,baseline data,imaging,and laboratory findings between the groups.Multivariate logistic regression analysis was used to determine the independent correlation between NLR and the outcomes,and receiver operating characteristics (ROC) analysis was performed to assess the predictive value of NLR for the outcomes.Results A total of 205 patients with acute intracerebral hemorrhage were enrolled in the study,107 (52.2％) had poor outcome and 57 (27.8％) died.There were significant differences in age (P=0.038),Glasgow Coma Scale (GCS) scores (P=0.001),National Institutes of Health Stroke Scale (NIHSS) scores (P =0.001),neutrophil count (P =0.005),lymphocyte count (P =0.002),NLR (P =0.001),fasting blood glucose (P =0.012),hypersensitivity C-reactive protein (P=0.002),hematoma volume (P =0.005),and proportion of bleeding into the ventricles (P =0.002) between the poor outcome group and the good outcome group.There were significant differences in age (P =0.002),previous stroke (P =0.018),GCS scores (P =0.001),NIHSS scores (P =0.001),neutrophil count (P=0.008),lymphocyte count (P=0.001),NLR (P=0.001),fasting blood glucose (P=0.016),hematoma volume (P=0.001),and proportion of bleeding into ventricle (P=0.002) between the death group and the survival group.Multivariate logistic regression analysis showed that NLR was an independent predictive factor for poor outcome (odds ratio [OR] 2.405,95％ confidence interval [CI] 1.613-3.587;P=0.001) and death (OR 2.268,95％ CI 1.532-3.358;P =0.001) after adjusting for confounders.The ROC curve analysis showed that NLR had a higher predictive value for poor outcome at 90 d (area under the ROC curve 0.703,95％ CI 0.632-0.774;P ＜ 0.001).When the cutoff value was 2.3,the sensitivity and specificity were 61.7％ and 72.4％,respectively.NLR also had a predictive value for death within 90 d (area under the ROC curve 0.706,95％ CI 0.629-0.786;P =0.003).When the cutoff value was 2.2,the sensitivity and specificity were 63.2％ and 72.6％,respectively.Conclusion NLR may have certain predict value for outcomes in patients with acute intracerebral hemorrhage.

ObjectiveTo investigate the correlation between neutrophil to lymphocyte ratio (NLR) and cerebral microbleeds (CMBs) in patients with acute ischemic stroke.MethodsThe consecutive inpatients with acute ischemic stroke were prospectively enrolled.Gradient echo-T2*-weighted imaging was used to evaluate CMBs and their quantity.Univariate analysis was used to compare the baseline data between the CMB group and the non-CMB group.Multivariable logistic regression analysis was used to identify the independent correlation between NLR and CMBs.ResultsA total of 218 patients with acute ischemic stroke were prospectively enrolled, including 66 (30.3%) with CMBs.The age (64.7±6.6 years vs.66.9±8.6 years;t=2.052, P=0.041), high sensitive C-reactive protein (7.0[2.3-13.9] mg/L vs.8.9[4.0-28.1] mg/L;Z=2.008, P=0.045) and NLR (1.9[1.4-2.9] vs.2.3[1.7-3.6];Z=2.071, P=0.038) in the non-CMB group were significantly lower than those of the CMB group.Multivariate logistic regression analysis showed that NLR (odds ratio 1.276, 95% confidence interval 1.008-1.670;P=0.045) and age (odds ratio 1.044, 95% confidence interval 1.002-1.087;P=0.040) were the independent risk factor for CMBs.Spearman correlation analysis showed that NLR was significantly positively correlated with the severity of CMBs (r=0.210, P=0.007).ConclusionsIn patients with acute ischemic stroke, NLR was associated with CMBs and their severity, suggesting that inflammatory reaction might be involved in the occurrence of CMBs.

Objective To explore the predictive value of brain lobe location of stroke lesion to development of long-term post-stroke depression(PSD)in the first-episode ischemic stroke patients for providing evidence for early intervention.Methods In the prospective study,158 patients aged 60 and over with first-episode ischemic stroke were continuously admitted into Department of Neurology of Shangqiu First People's Hospital from January 2013 to July 2013.The 2 to 3 years follow-up after stroke episode was performed in 126 cases for inquiring into correlation between brain lobe location of stroke lesion and development of PSD.The diagnosis of depression was in accordance with Mental Disorders Diagnostic and Statistical Manual 4(DSM-Ⅳ)standard,and divided into groups of stroke with depression(n=52)and stroke without depression(n=74).The degree of depression was evaluated by 17-item Hamilton Rating Scale for Depression(HAMD17).The location,number and volume of stroke lesions were determined by head MRI.The relationship between PSD and pathogenetic loci was analyzed by unconditional Logistic regression analysis.A difference in hemisphere commensalism.Results The morbidity of PSD was 41.3%(52/126),with 21.4%(27/126),12.7%(16/126),7.1%(9/126)in mild,moderate and severe PSD respectively.The frontal lobe(OR=2.824,95%CI=1.189-6.706)and the temporal lobe(OR=3.579,95%CI=1.233-10.393)cerebral infarction were correlated with the occurrence of PSD.The long-term PSD severity was more in frontal lobe than in temporal lobe(χ2=6.399,P<0.05).The average volume of cerebral infarction was larger in PSD group than in non-PSD group(t=3.271,P<0.05),and the average number of cerebral infarction loci was more in PSD group than in non-PSD group(t=3.176,P<0.05).The more severe the degree of depression according to HAMD17,the larger the average volume of cerebral infarction(F=6.280,P<0.05)and the more the average number of lesions(F=6.132,P<0.05).Conclusions The development of long-term PSD in the first-episode elderly patients is affected by the invasion site.The frontal lobe and temporal lobe infarction are independent risk factors for long-term PSD in patients with ischemic stroke,and the PSD was more severe in frontal lobe infarction than in temporal lobe infarction.
