Objective To investigate the impact of ampelopsin(AMP)on oxygen glucose deprivation/reperfusion(OGD/R)induced neuronal damage and its mechanism,and to lay a foundation for the study of neonatal hypoxic-ischemic brain damage.Methods Neurons of newborn SD rats were isolated and cultured in vitro,and they were divided into 5 groups:control group(AMP 0 μmol/L),OGD/R group,low dose AMP group(OGD/R+AMP 20 μmol/L),high dose AMP group(OGD/R+AMP 30 μmol/L)and JAK2/STAT3 activator group(OGD/R+AMP 30 μmol/L+Coumermycin A1 10 μmol/L).CCK-8 method was used to de-tect the cell viability of different treatment groups,the lactate dehydrogenase(LDH)kit was used to detect the cell activity of LDH in the medium,flow cytometry was used to detect the apoptosis rate,enzyme-linked immunosorbent assay was used to detect the levels of interleukin-6(IL-6),interleukin-10(IL-10)and tumor necrosis factor α(TNF-α),the kit was used to detect the levels of reactive oxygen species(ROS),malondial-dehyde(MDA)and superoxide dismutase(SOD),and Western blotting was used to detect the expression of apoptosis related proteins B-cell lymphoma-2(Bcl-2),Bcl-2 associated X protein(Bax),enzymatic cleavage of cysteine containing aspartate protein hydrolase-3(C-caspase-3),tyrosine kinase 2(J AK2),phosphorylated JAK2(p-JAK2),signal transduction and transcription activating factor 3(STAT3)and phosphorylated STAT3(p-STAT3).Results Compared with the concentration of AMP of 0 μmol/L,the cell viability in con-centration of AMP of 5-30 μmol/L was not obvious different(P＞0.05),when the concentration of AMP was 40 μmol/L,the cell viability decreased obviously(P＜0.05).Compared with the control group,the cell viability,the levels of SOD fluorescence intensity,IL-10 and Bcl-2 in OGD/R group decreased obviously,the LDH activity,cell apoptosis rate,the levels of ROS,MDA,IL-6,TNF-α,Bax,C-caspase-3,p-JAK2/JAK2,and p-STAT3/STAT3 increased obviously(P＜0.05).Compared with OGD/R group,the cell viability,the levels of SOD fluorescence intensity,IL-10 and Bcl-2 in low and high dose AMP groups increased,the LDH activity,cell apoptosis rate,the levels of ROS,MDA,IL-6,TNF-α,Bax,C-caspase-3,p-JAK2/JAK2,and p-STAT3/STAT3 decreased(P＜0.05),and JAK2/STAT3 activator was able to reverse the protective effect of AMP on OGD/R induced neuronal.Conclusion AMP attenuates OGD/R induced neuronal by reducing oxidative stress and inflammatory response,and its mechanism may be related to inhibition of JAK2/STAT3 signal pathway phosphorylation.

Child safety seats have been proven to be one of the most effective tools for protecting child passengers. However, the widespread phenomenon of safety seats being "unavailable," "owned but not used," or "used incorrectly" is prevalent globally. This paper aims to summarize the obstacles to the use of child safety seats from four aspects: Individual, society, environment and policy, in order to provide a basis for follow-up comprehensive intervention to ensure the safety of children.

Objective:To compare the correlation and consistency of central corneal thickness (CCT) measured by four different instruments, specular microscope SP-1P, IOLMaster 700, Pentacam HR and RTVue XR-OCT.Methods:A diagnostic test study was performed.A total of 50 right eyes of 50 consecutive outpatients who planned to undergo corneal refractive surgery at Hanyang Aier Eye Hospital from January to May 2022 were included.CCT was measured with the specular microscope SP-1P, IOLMaster 700, Pentacam HR and RTVue XR-OCT, respectively.The differences of CCT measurements by the four instruments were compared.The correlation and consistency between the CCT values was analyzed by Pearson linear analysis and Bland-Altman test, respectively.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Hanyang Aier Eye Hospital (No.HYEYE20221229JM).Written informed consent was obtained from each subject.Results:The mean CCT values measured by SP-1P, IOLMaster 700, Pentacam HR and RTVue XR-OCT were (522.68±30.08), (544.06±32.85), (541.00±31.75) and (528.86±31.60)μm, respectively, with a statistically significant overall difference ( F=5.09, P=0.002).CCT measurements obtained with SP-1P were lower than those obtained with IOLMaster 700 and Pentacam HR, while the IOLMaster 700 measurements were higher than those of RTVue XR-OCT, showing statistically significant differences (all at P<0.05).Pearson correlation analysis revealed significant positive correlations of CCT measurements between SP-1P and IOLMaster 700, SP-1P and Pentacam HR, SP-1P and RTVue XR-OCT, IOLMaster 700 and Pentacam HR, IOLMaster 700 and RTVue XR-OCT, Pentacam HR and RTVue XR-OCT ( r=0.988, 0.980, 0.988, 0.981, 0.982, 0.973; all at P<0.01).Bland-Altman consistency analysis showed that the 95% limits of agreement (95% LoA) for CCT measurements between SP-1P and RTVue XR-OCT, IOLMaster 700 and Pentacam HR were -16.46-6.14 and -10.56-14.48 μm, respectively, with 3(6%) and 2(4%) data points outside the 95% LoA, respectively.The mean difference lines for the CCT measurements were close to 0, indicating good consistency and clinically acceptable differences without statistical significance. Conclusions:CCT values measured with specular microscope SP-1P and RTVue XR-OCT, as well as those measured with IOLMaster and Pentacam HR, are relatively close in patients with low to moderate myopia, show good consistency and can therefore be considered interchangeable.

Migraine is one of the most prevalent and disabling neurological disease, but the current pharmacotherapies show limited efficacy and often accompanied by adverse effects. Acupuncture is a promising complementary therapy, but further clinical evidence is needed. The influence of acupuncture on migraine is not an immediate effect, and its mechanism remains unclear. This study aims to provide further clinical evidence for the anti-migraine effects of acupuncture and explore the mechanism involved. A randomized controlled trial was performed among 10 normal controls and 38 migraineurs. The migraineurs were divided into blank control, sham acupuncture, and acupuncture groups. Patients were subjected to two courses of treatment, and each treatment lasted for 5 days, with an interval of 1 day between the two courses. The effectiveness of treatment was evaluated using pain questionnaire. The functional magnetic resonance imaging (fMRI) data were analyzed for investigating brain changes induced by treatments. Blood plasma was collected for metabolomics and proteomics studies. Correlation and mediation analyses were performed to investigate the interaction between clinical, fMRI and omics changes. Results showed that acupuncture effectively relieved migraine symptoms in a way different from sham acupuncture in terms of curative effect, affected brain regions, and signaling pathways. The anti-migraine mechanism involves a complex network related to the regulation of the response to hypoxic stress, reversal of brain energy imbalance, and regulation of inflammation. The brain regions of migraineurs affected by acupuncture include the lingual gyrus, default mode network, and cerebellum. The effect of acupuncture on patients' metabolites/proteins may precede that of the brain.

Objective:To investigate the therapeutic effect and safety of pomadomide combined with cyclophosphamide and dexamethasone (PCD) in the treatment of relapsed/refractory multiple myeloma (MM).Methods:The clinical data of 20 relapsed/refractory MM patients receiving PCD regimen in the Second People's Hospital of Lianyungang Affiliated to Bengbu Medical College from March 2021 to June 2022 were retrospectively analyzed; and 29 relapsed/refractory MM patients receiving other regimens including DECP (dexamethasone+etoposide+cyclophosphamide+cisplatin, 13 cases) and VCD (bortezomib+ cyclophosphamide+ dexamethasone, 16 cases) during the same period were treated as the control group. The efficacy and adverse effects of both groups were compared after 4 cycles of treatment.Results:After 4 cycles of treatment, the overall response rate (ORR) and the clinical benefit rate (CBR) of 20 cases in PCD group was 70.0% (14/20) and 85.0% (17/20), respectively; among 20 cases, there were 5 cases of complete response (CR), 4 cases of very good partial remission (VGPR), 5 cases of partial remission (PR), 3 cases of minimal remission (MR), 2 cases of stable disease (SD), 1 case of the progression of the disease (PD). ORR and CBR of 29 cases in the control group was 41.4% (12/29) and 65.5% (19/29), respectively; among 29 cases, there were 2 cases of CR, 3 cases of VGPR, 7 cases of PR, 7 cases of MR, 5 cases of SD, 5 cases of PD. There was a statistically significant difference in ORR of both group ( χ2 = 3.89, P = 0.048), while the difference in CBR of both group was not statistically significant ( χ2 = 2.30, P = 0.129). There were 2 patients with renal impairment achieving CR in PCD group and 1 patient with renal impairment achieving CR in the control group ( P = 0.152); 1 genetically high-risk patient achieved CR in PCD group and none of patients in the control group achieved CR, and the difference was statistically significant ( P>0.05). The common hematological adverse effects of two groups were anemia, neutropenia, thrombocytopenia; the common non-hematological adverse effects were malaise, infection and fatigue, and the differences were statistically significant (all P>0.05). The incidence of grade 3-4 infection was 25.0% (5/20) in PCD group and the disease was under the control after anti-infective therapy, and the incidence of grade 3-4 infection was 24.1% (7/29) in the control group; and the difference was not statistically significant ( P > 0.05). Conclusions:PCD regimen has good clinical efficacy and safety in treatment of relapsed/refractory MM.

Background: and Purpose To evaluate whether the thrombus enhancement sign (TES) can be used to differentiate embolic large vessel occlusion (LVO) from in situ intracranial atherosclerotic stenosis (ICAS)-related LVO in the anterior circulation of patients with acute ischemic stroke (AIS). Methods: Patients with LVO in the anterior circulation who underwent both non-contrast computed tomography (CT) and CT angiography and mechanical thrombectomy were retrospectively enrolled. Both embolic LVO (embo-LVO) and in situ ICAS-related LVO (ICAS-LVO) were confirmed by two neurointerventional radiologists after reviewing the medical and imaging data. TES was assessed to predict embo-LVO or ICAS-LVO. The associations between occlusion type and TES, along with clinical and interventional parameters, were investigated using logistic regression analysis and a receiver operating characteristic curve. Results: A total of 288 patients with AIS were included and divided into an embo-LVO group (n=235) and an ICAS-LVO group (n=53). TES was identified in 205 (71.2%) patients and was more frequently observed in those with embo-LVO, with a sensitivity of 83.8%, specificity of 84.9%, and area under the curve (AUC) of 0.844. Multivariate analysis showed that TES (odds ratio [OR], 22.2; 95% confidence interval [CI], 9.4–53.8; P<0.001) and atrial fibrillation (OR, 6.6; 95% CI, 2.8–15.8; P<0.001) were independent predictors of embolic occlusion. A predictive model that included both TES and atrial fibrillation yielded a higher diagnostic ability for embo-LVO, with an AUC of 0.899. Conclusion TES is an imaging marker with high predictive value for identifying embo- and ICAS-LVO in AIS and provides guidance for endovascular reperfusion therapy.

In China, the survival rate of liver cancer remains low while the mortality rate is high. Effectively reducing the burden of liver cancer is still a major challenge in the field of public health and chronic disease prevention in the Chinese population. Optimizing screening strategies for liver cancer remains a profound approach to secondary prevention worthy of continuous exploration. To address this pressing issue, the Bureau of Disease Control and Prevention of the National Health Commission commissioned this guideline. The National Cancer Center of China initiated the guideline development and convened a multidisciplinary expert panel and working groups. Following the World Health Organization Handbook for Guideline Development, this guideline integrated the most up-to-date evidence of liver cancer screening, China's national conditions, and existing practical experience in liver cancer screening. Evidence-based recommendations on the target population, screening technologies, surveillance strategies, and other key points across the process of liver cancer screening and surveillance management were provided. This guideline would help standardize the practice of liver cancer screening in China.
