Objective At present, the risk factors for cognitive impairment in epilepsy patients are not quite clear.This study was to explore the impacts of the clinical features, emotional health and quality of life (QOL) on the cognitive function of the adult patients with mild cognitive impairment (MCI).Methods Using the Montreal Cognitive Assessment (MoCA) and Mini Mental State Examination (MMSE) scales, we evaluated the cognitive functions of the 109 adult epileptics of the outpatient clinic of neurology in Jinling Hospital.We assessed their emotional health with Hamilton Depression Scale-24 (HAMD-24), estimated their QOL with Quality Of Life in Epilepsy-31 (QOLIE-31), and collected their baseline clinical data by questionnaire survey.Results There were 67 cases of MCI (61.5%) among the 109 patients.The residential area was the strongest predictor of MCI in the adult epileptics (OR=0.226, 95% CI: 0.082-0.627).Among other risk factors of post-epileptic MCI were the total scores of HAMD-24 (OR=0.770, 95% CI: 0.644-0.921) and QOLIE-31 (OR=0.712, 95% CI: 0.575-0.880), QOL (OR=1.070, 95% CI: 1.015-1.128), cognitive function (OR=1.120, 95% CI: 1.043-1.203), and social function (OR=1.103, 95% CI: 1.035-1.175).Conclusion The incidence of MCI is high in adult patients with epilepsy.The development and progression of post-epileptic MCI can be delayed by more emphasis on the evaluation of cognitive function, emotional health, and quality of life.

Objective: To observe the promoting blood circulation by removing blood stasis of Lubai Capsule(LBC)(Rhizoma Phragmitis, Radix Paeoniae Alba, Radix Saposhnikoviae, Flos Schizonepetae, etc.). Methods: Acute blood stasis rat models were established with swimming in iced water and sc adrenalin in order to observe the effect of LBC on blood rheology. Mesenteric microcirculatory disturbance rat models were also established with adrenalin in order to observe the effect of LBC. Clotting time was measured in vitro with prothrombin time(PT) and kaolin partial thromboplastin time(KPTT) kit in order to observe its effects. Results: LBC could decrease the whole blood and plasma viscosity, fibrinogen, erythrocyte sedimentation and aggregation ratio of blood platelets of rats, ease the sticky condition of blood stasis rat models and prevent from forming thrombus. It could also inhibit the constraction and slowing of blood flow of thin artery, the reducing of open capillaries and change of fluid condition caused by adrenalin and improve these phenomena. PT and KPTT could be increased obviously. Conclusion: LBC can significantly promote blood circulation by removing blood stasis, because of improving blood rheology and mesenteric microcirculatory disturbance and inhibit endogenous and exogenous coagulation system.

Objective: To explore the correlation between serum level of high molecular weight adiponectin (HMW-ADPN) and arteriosclerosis. Methods: Clinical data of 87 middle-aged and aged people living in home, who underwent health examinations in Xiangya second hospital from Jan 2011 to Dec 2011, were collected. According to carotid-femoral pulse wave velocity (cf-PWV) = 9 m/s, they were divided into group A (cf-PWV<9 m/s, n=21) and group B (cf-PWV≥9 m/s, n=66). Blood pressure, blood lipid, blood glucose etc. were measured and compared between two groups. Results: Compared with group A, there were significant rise in blood pressure, levels of low density lipoprotein cholesterol, triglyceride and total cholesterol, and significant reduction in levels of high density lipoprotein cholesterol (HDL-C), serum total ADPN and HMW-ADPN in group B, P<0.05 or <0.01. Multiple regression analysis indicated that serum HMW-ADPN (B= - 4.469，P=0.011), total ADPN ((B= - 3.965，P=0.012), HDL-C（B= - 2.077，P=0.015) and systolic blood pressure levels (B= 0.045，P=0.045) were independent predictors of cf-PWV. Conclusion: Serum high molecular weight adiponectin and total adiponectin levels may be protective factors against arteriosclerosis. Its role in predicting occurrence and development of arteriosclerosis is worthy of further study.

Objective: To study the relationship between serum levels of insulin-like growth factor-1 (IGF-1), cystation-C (Cys-C), interleukin-6 (IL-6) and atherosclerosis in middle and old age patient with newly diagnosed type 2 diabetes mellitus (T2DM). Methods: A total of 206 patients with newly diagnosed T2DM at the age of (67.3±10.4) years were enrolled. Based on color Doppler ultrasound examination, the patients were divided into 2 groups: Control group, the patient without carotid plaque or increased intima thickening, n=105 and Experiment group, patient with carotid plaque or increased intima thickening, n=101. The general information, fasting blood glucose, 2h postprandial blood glucose, glycosylated hemoglobin, LDL-C, HDL-C, TG, TC and IGF-1, Cys-C, IL-6, hs-CRP were recorded and compared between 2 groups, BMI was calculated in all patients. Results: Compared with Control group, Experiment group had increased carotid intima-media thickness (CIMT), elevated serum levels of Cys-C, IL-6, hs-CRP and reduced IGF-1, allP<0.05. Multiple Logistic regression analysis showed that CIMT was negatively related to IGF-1 (r=-0.493,P<0.01), positively related to Cys-C, IL-6 and hs-CRP (r=0.464,r=0.219 andr=0.618, allP<0.01). Conclusion: Serum levels of Cys-C and IL-6 might be the independent risk factors for atherosclerosis occurrence in meddle and old patients with T2DM; combined detection of IGF-1, Cys-C and IL-6 could help clinical diagnosis in relevant patients.

Objective To explore the efficacy of the retrosigmoid sinus approach through the cerebellopontine angle in the treatment of pontine hemorrhage.Methods A retrospective analysis was performed on 108 patients with pontine hemorrhage in Kaifeng Central Hospital from January 2016 to June 2022.They were divided into two groups according to the treatment methods,the conservative treatment group and the craniotomy treatment group(transcerebellopontine angle sigmoid sinus posterior approach).There were 94 cases in the conservative treatment group and 14 cases in the surgical treatment group.First analysis was conducted to examined whether there are differences in gender,age,Glasgow Coma Score(GCS)on admission,bleeding volume,comorbidities and complications between the two groups.Additional analysis was performed to analyze modified Rankin(modified Rankin scale,mRS)score and mortality rate after three month follow-up in case there was no significant difference at first analysis.Results There were no statistical differences in gender,age,Glasgow Coma Score(GCS)on admission,bleeding volume,comorbidities and complications between the two groups.After 3 months of follow-up,49 patients died in the conservative treatment group and 3 patients in the craniotomy treatment group.The mortality rates of the two groups were 52.1％and 21.4％respectively(χ2=4.600,P<0.05)).There was a statistical difference in the mortality rate between the two groups,and the mortality rate of the craniotomy treatment group was significantly lower than that of the conservative group.The modified Rankin score was 4(3,5)in the conservative treatment group and 3(2,3)in the craniotomy group(Z=-2.994,P<0.01).The modified Rankin score in the craniotomy group was lower than that in conservative treatment group after 3 months.Conclusion Microsurgery through the cerebellopontine angle retrosigmoid sinus approach to treat pontine hemorrhage can significantly reduce patient mortality and improve prognosis and is an effective surgical treatment method.

ObjectiveTo investigate the therapeutic effect of Dayuanyin on acute lung injury induced by H1N1 infection and decipher the potential mechanism. MethodThe constituents in Dayuanyin were analyzed by ultra-high performance liquid chromatography-quadrupole-exactive orbitrap mass spectrometry （UHPLC-Q-Exactive Orbitrap MS）. Forty-eight female BALB/c mice were randomized into normal， model， oseltamivir （19.5 mg·kg^-1）， and low-， medium-， and high-dose （2.73， 5.46， 10.92 g·kg^-1） Dayuanyin groups. The normal and model groups were administrated with deionized water by gavage， and the other groups were administrated with the corresponding drugs by gavage. On day 3 of drug administration， the normal group received nasal inhalation of normal saline， and the other groups were inoculated intranasally with A/RP/8/34 （H1N1） for the modeling of influenza virus infection. Mice were administrated with drugs continuously for 7 days and weighed daily. Sampling was performed 12 h after the last administration， and the lung tissue was weighed to calculate the lung index. Hematoxylin-eosin staining was performed to observe the pathological and morphological changes of the lung tissue and bronchi. The cytometric bead array （CBA） was used to measure the serum levels of interferon-gamma （IFN-γ）， C-X-C motif ligand 1 （CXCL1）， tumor necrosis factor-alpha （TNF-α）， chemokine ligand 2 （CCL2）， interleukin-12p70 （IL-12p70）， chemokine ligand 5 （CCL5）， interleukin-1β （IL-1β）， chemokine （C-X-C motif） ligand 10 （CXCL10）， granulocyte-macrophage colony-stimulating factor （GM-CSF）， interleukin-10 （IL-10）， interferon-beta （IFN-β）， interferon-alpha （IFN-α）， and interleukin-6 （IL-6）. According to the results of mass spectrometry and network pharmacology， we analyzed the mechanism of Dayuanyin in treating acute lung injury caused by H1N1. The protein levels of extracellular signal-regulated kinase 1/2 （ERK1/2）， p38 mitogen-activated protein kinase （p38 MAPK）， nuclear factor-kappa B （NF-κB）， and their phosphorylated forms were determined by Western blot. The mRNA levels of myeloid differentiation factor 88 （MyD88）， Toll-like receptor 3 （TLR3）， Toll-like receptor 7 （TLR7）， and Toll-like receptor 8 （TLR8） in the lung tissue were measured by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultA total of 57 compounds， including paeoniflorin and baicalein， were detected in Dayuanyin. Compared with the normal group， the model group showed decreased body weight （P<0.01）， lung edema and hemorrhage， increased lung index （P<0.01）， and elevated levels of IFN-γ， IL-12p70， CCL5， IL-1β， CXCL10， GM-CSF， IFN-β， and IL-6 （P<0.01）. Compared with the model group， Dayuanyin attenuated alveolar wall thickening， capillary congestion， and immune cell infiltration， reduced the alterations in body weight and lung index （P<0.01）， and down-regulated the protein levels of IFN-γ， IL-12p70， CCL5， IL-1β， CXCL10， GM-CSF， IFN-β， and IL-6 （P<0.01）. A total of 57 key genes were predicted by network pharmacological analysis， of which the MAPK signaling pathway was the main target signaling pathway. Compared with the normal group， the model group showed up-regulation in the protein levels of phosphorylation （p）-ERK1/2， p-p38 MAPK， and p-NF-κB （P<0.01） and the mRNA levels of TLR7， TLR8， MyD88， and TLR3 （P<0.05， P<0.01）. Compared with the model group， Dayuanyin lowered the phosphorylation levels of ERK1/2， p38 MAPK， and NF-κB p65 in a dose-dependent manner （P<0.01） and down-regulated the mRNA levels of TLR3， TLR7， TLR8， and MyD88 （P<0.01）. ConclusionDayuanyin can prevent and control H1N1 infection-induced acute lung injury by inhibiting the TLR/MAPK/NF-κB signaling pathway.

OBJECTIVES: Shelter hospital was an alternative way to provide large-scale medical isolation and treatment for people with mild coronavirus disease 2019 (COVID-19). Due to various reasons, patients admitted to the large shelter hospital was reported high level of psychological distress, so did the healthcare workers. This study aims to introduce a comprehensive and multifaceted psychosocial crisis intervention model. METHODS: The psychosocial crisis intervention model was provided to 200 patients and 240 healthcare workers in Wuhan Wuchang shelter hospital. Patient volunteers and organized peer support, client-centered culturally sensitive supportive care, timely delivery of scientific information about COVID-19 and its complications, mental health knowledge acquisition of non-psychiatric healthcare workers, group activities, counseling and education, virtualization of psychological intervention, consultation and liaison were exhibited respectively in the model. Pre-service survey was done in 38 patients and 49 healthcare workers using the Generalized Anxiety Disorder 7-item (GAD-7) scale, the Patient Health Questionnaire 2-item (PHQ-2) scale, and the Primary Care PTSD screen for the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (PC-PTSD-5). Forty-eight healthcare workers gave feedback after the intervention. RESULTS: The psychosocial crisis intervention model was successfully implemented by 10 mental health professionals and was well-accepted by both patients and healthcare workers in the shelter hospital. In pre-service survey, 15.8% of 38 patients were with anxiety, 55.3% were with stress, and 15.8% were with depression; 16.3% of 49 healthcare workers were with anxiety, 26.5% were with stress, and 22.4% were with depression. In post-service survey, 62.5% of 48 healthcare workers thought it was very practical, 37.5% thought more practical; 37.5% of them thought it was very helpful to relief anxiety and insomnia, and 27.1% thought much helpful; 37.5% of them thought it was very helpful to recognize patients with anxiety and insomnia, and 29.2% thought much helpful; 35.4% of them thought it was very helpful to deal with patients' anxiety and insomnia, and 37.5% thought much helpful. CONCLUSIONS Psychological crisis intervention is feasible, acceptable, and associated with positive outcomes. Future tastings of this model in larger population and different settings are warranted.
