Objective:To examine the occurrence of seizures and perioperative risk factors in children after obtaining cardiopulmonary bypass (CPB).Methods:Electroencephalograph (EEG) and cerebral oxygen saturation (ScO 2) were monitored in 87 patients (aged 3 days-110 months, with the median at 4.4 months) and they were admitted to the Cardiac Intensive Care Unit (CICU) from May 2018 to April 2019, with 77 patients for 72 h after CPB and 10 cases with clinical seizures after CICU discharge for 8-180 h. Clinical data were recorded every 4 hours, including blood pressure, central venous pressure (CVP), temperature, arterial blood gases, lactate, doses of Dopamine, Milrinone, and Adrenalin, and daily C-reaction protein (CRP) and N-terminal pro-brain natriuretic peptide(NT-proBNP). Demographic data, the Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery(STAT) mortality classification and clinical outcomes (duration of mechanical ventilation, CICU and hospital stay, and death) were recorded. Results:Seizures occurred in 24 patients (27.6%) within 48 h after CPB.EEG seizures appeared in 7 patients, both EEG and clinical seizures in 7 patients, and clinical seizures in 10 patients.Three patients developed epilepsy.There were 2 hospital deaths and both had EEG seizures.Patients with seizures had higher STAT categories, longer operative time and worse clinical outcomes (all P<0.05). Univariate regression revealed that the occurrence of seizures was positively related to adrenalin, temperature, lactate level (all P<0.01), blood pressure, CVP (all P<0.05) and CRP ( P<0.1), and negatively correlated with arterial carbon dioxide tension[ pa(CO 2)], ScO 2 and dose of Milrinone (all P<0.05). In multivariate regression, only dose of Adrenalin ( P<0.001) and lactate level ( P<0.01) remained significant. Conclusions:The incidence of seizures was high in children after CPB.Numerous perioperative factors that were related to seizures were identified.The most significant risk factors were higher dose of adrenaline and lactate level.Studies on neurological injury after CPB are urgently needed in China in order to reduce brain injury and improve neurodevelopmental outcomes.

Campylobacter is a major cause of food-borne gastroenteritis worldwide. While mortality is low when people was infected with Campylobacter, morbidity imparted by post-infectious sequelae such as Guillain-Barré syndrome and irritable bowel syndrome is significantly noteworthy. Although fluoroquinolones and macrolides were the first line drug for the treatment of Campylobacter infections, there is a tough challenge in clinical treatment with high antimicrobial resistant rate and multi antimicrobial resistance arise. Based on the latest literature acquired in this work, we have chosen five classes of antibiotics always used in clinical, and discussed antibiotic resistance mechanisms and transmission of Campylobacter, in order to provide proper therapy both in the veterinary and human populations, and support basis data for the development of new drugs.

Objective:To optimize the clinical nursing pathway, service program and evaluation parameters of percutaneous coronary intervention(PCI), for references for the cost accounting and compensation mechanism of nursing program in public hospitals.Methods:After literature analysis and group discussion, the initial templates were constructed for the PCI clinical nursing pathway, nursing service projects, and their evaluation parameters. 15 experts were consulted by two rounds of Delphi method to optimize PCI nursing path, nursing service items and their evaluation parameters (basic labor consumption, basic time consumption, technical difficulty and risk degree).Results:Two rounds of Delphi method finally determined the PCI clinical nursing path and 27 nursing service items, and adjusted the evaluation parameters of 10 nursing service items. The new projects for PCI clinical nursing services included adjustment and review of dual antiplatelet therapy plans, postoperative rehabilitation nursing, and key project verification. The three nursing service projects with the highest level of technical difficulty and risk were intravenous blood transfusion, gastric catheterization, and gastrointestinal decompression. The two items with the highest importance assigned were high pump assisted arterial/venous infusion (blood) and invasive continuous arterial blood pressure monitoring.Conclusions:The PCI clinical nursing pathway and nursing service project constructed in this study could closely integrate with clinical practice, highlight the integrated nursing service model, and reflect the labor value of nurses.

Objective To investigatethe significance of serum carbohydrate antigen (CA) 125,car cinoembryonic antigen (CEA),cytokeratin 19 fragment (CYFRA21-1),neuron-specific enolase (NSE),and squamous cell carcinoma antigen (SCCA) in the diagnosis of bone metastasis from lung cancer.Methods A total of 222 patients,including 91 lung cancer patients with bone metastasis (49 males,42 females,average age (60.07± 10.60) years;group A),75 lung cancerpatientswithout bone metastasis (57 males,18 females,average age (62.20± 12.63) years;group B),56 patients with benign lung diseases (34 males,22 females,average age (61.45± 10.66) years;group C) were recruited from January 2015 to January 2016.The electrochemiluminescence was applied to detect serum levels of CA125,CEA,CYFRA21-1,NSE and SCCA.Kruskal-Wallis,Wilcoxon rank sum test,x2 test and receiver operating characteristic (ROC) curve analysis were used to analyze data.Results The levels of serum CA125,CEA,CYFRA21-1,NSE in group A were higher than those in group B and C (H values:13.45-44.96,all P＜0.05);while SCCA was not significantly different among the 3 groups (H=2.56,P＞0.05).The areas under ROC curves for CA125,CEA,CYFRA21-1,NSE,SCCA were 0.667,0.702,0.602,0.664,0.440,respectively.The positive rate of serum NSE in small cell lung cancer (SCLC) patients was higher than that in non-small-cell lung cancer (NSCLC) patients (17/18 vs 32.88％ (24/73);x2=22.11,P＜0.05);CEA was highly expressed in adenocarcinoma,and SCCA was highly expressed in squamous cell carcinoma.Patients with grade Ⅲ+ Ⅳ metas tasis (n =52) had higher levels of CA 125,CEA,NSE compared to patients with Ⅰ + Ⅱ metastasis (n =39;z values:from-2.54 to-0.32,all P＜0.05).The sensitivity of combined detection of 5 tumor markers was 97.80％ (89/91),which was significantly higher than that of single tumor marker (x2 values:35.46-138.23,all P＜0.05).Conclusion Serum levels of CA125,CEA,CYFRA21-1,NSE and SCCA play a role in the diagnosis of bone metastasis from lung cancer,and the combined detection of the 5 tumor markers contribute to the early detection of bone metastases.

Objective To explore EEG characteristics and the therapeutic effect in children with electrical status epilepticus during slow sleep(ESES).Methods The eligible ESES cases in our center from 2014 to 2020 were included.The age at diagnosis of ESES,the duration of ESES,spike wave index(SWI)during wakefulness and the distribution of spike wave during the period of ESES,age at seizure onset,the clinical syndromes and the outcomes after treatment were analyzed.The ESES cases were divided into 4 groups according to the distribution of spike wave:focal ESES,unilateral ESES,bilateral asymmetric ESES,multiple foci ESES.The SWI during the awake stage were divided into 3 groups based on the different rates:≤20%,21%～49%,≥50%.The therapeutic outcomes were classified into three groups:satisfactory response,seizure control and ineffective.Results 50 cases were included,with 32 males and 18 females.The average onset age of ESES was 6 years and 7 months,and the average duration of ESES was 28 months.A significant correlation between the distribution of ESES and the thera-peutic effects was found,bilateral asymmetric ESES had a good therapeutic effects,while multiple foci ESES showed a poor therapeutic effects.The duration of ESES was significantly correlated with therapeutic effects,and the efficacy was worse when the duration was longer than 1 year.A significant relationship between the SWI during wakefulness of ESES and the therapeutic effects was detected,the patient with SWI≤20%during wakefulness had a good therapeutic effect.There was a negative correlation between the onset age of ESES and the duration of ESES and SWI index during wakefulness.There was a positive correlation between the duration of ESES and SWI index during wakefulness.Conclusion Our results suggest that onset age,distribution,duration and SWI during wake-fulness of ESES were correlated with therapeutic outcomes,The patient with SWI≤20%during wakefulness had a good therapeutic effect and have unfavorable outcomes with ESES last more than 1 year.The earlier onset of ESES,the longer duration of ESES and higher SWI during wakefulness will be showed..

Senile macular degeneration（SMD） is a degenerative disease of the macular region of the eye that causes visual impairment in older people worldwide. It is the focus and difficulty of the treatment of ophthalmic diseases at home and abroad. This paper reviewed traditional Chinese medicine （TCM） active ingredients for the treatment and prevention of SMD， and its new ocular delivery preparations. Studies have shown that many active ingredients of TCM can inhibit the progression of SMD through various ways such as anti-oxidation， solid lipid nanoparticles， microemulsions/nanoemulsions， in-situ gel， etc. However， due to the low solubility， chemical instability and difficulty in overcoming the eye barrier of most TCM active ingredients， their clinical application in the treatment of SMD is seriously hindered. New preparations， such as liposomes， solid lipid nanoparticles， microemulsion/nanoemulsion， in situ gels， have good application prospects in ocular drug delivery.

Objective:To investigate the prevalence and risk factors of diabetic retinopathy (DR) in patients in Tibet.Methods:A total of 239 patients with DR who received treatment in Department of Endocrinology and Metabolism, Hospital of Chengdu Office of People's Government of Tibet Autonomous Region from December 2017 to December 2018 were included in this study. They were divided into Han nationality and Zang nationality groups according to ethnicity. The condition of DR was evaluated with nonmydriatic ocular fundus photography according to the staging criteria of the severity of retinopathy.Results:The prevalence of DR in Tibet was 18.0％. The prevalence of DR in Tibetan and Han patients with diabetes was 17.5% and 19.2%, respectively. There was no significant difference in the prevalence of DR between Tibetan and Han patients with diabetes ( χ2 = 0.10, P = 0.754). Logistic regression analysis revealed that the risk factors of developing DR in Tibet included diabetes duration ( OR = 1.14, 95% CI: 1.05-1.24, P < 0.05), insulin therapy ( OR = 2.74, 95% CI: 1.09-6.89, P < 0.05), fasting plasma glucose ( OR = 1.37, 95% CI: 1.07-1.75, P < 0.05) and hypertension ( OR = 1.98, 95% CI: 1.02-3.86, P < 0.05). Diabetes duration and fasting plasma glucose are independent risk factors of DR. However, although elevated glycated hemoglobin levels were high in Tibet, they could not be used to predict the risk for developing DR ( OR = 1.01, 95% CI: 0.82-1.25, P > 0.05). Conclusion:Hyperglycemia is an important risk factor of developing DR in Tibet. However, elevated glycated hemoglobin levels cannot be used to predict the risk of developing DR in Tibet. Findings from this study fill the gap in the research on DR prevalence and ethic difference of DR prevalence, providing scientific evidence for prevention and treatment of DR in high-altitude areas.

Sleep deprivation refers to the loss of sleep caused by self-inflicted or external factors. There is increasing evidence that pregnancy is prone to sleep deprivation, which not only disrupts maternal functions but also affects offspring′s cognitive function. This article reviews the effects of sleep deprivation during pregnancy on offspring cognition and its underlying mechanisms, in order to establish a foundation for developing scientifically sound sleep strategies during pregnancy and to provide clinical insights for improving the neurodevelopment and cognitive function of offspring.

Objective To investigate the therapeutic effect of Shugan Heluo Xingpi Decoction on CCl 4 -induced liver fibrosis in rats, and the underlying molecular mechanism. Methods Sixty male SPF Wistar rats were randomly assigned to six groups: blank control, model, positive control, high, medium or low dose groups of Shugan Heluo Xingpi Decoction ( n =10 per group). The liver fibrosis rat model was induced by an intraperitoneal injection of 40% CCl 4 oil solution. Rats in the blank control and model groups were administered 10 mL/kg normal saline by gavage, rats in the positive control group were administered 50 mg/kg silibinin meglumine by gavage, while rats in high-dose, medium-dose and low-dose groups of Shugan Heluo Xingpi Decoction were administered 12.42 g/kg, 6.21 g/kg and 3.11 g/kg (crude drug/body weight) by gavage, respectively, daily for 8 weeks. Rats was sacrificed after 8 weeks, during which the physiological status of rats in each group was dynamically monitored. Following sacrifice, serum was collected to detect HYP using alkaline hydrolysis colorimetry and the expression levels of AST, ALT, total protein (TP), and Alb using an automatic biochemical analyzer. The pathological morphological changes in the liver were detected by H & E staining and Masson staining, and the mRNA and protein levels of Wnt1, β-Catenin and Cyclin D1 were detected by RT-qPCR and Western Blot. Measurement data were compared across groups using one-way ANOVA with post-hoc LSD- t test. Results Compared with the model group, after silibinin meglumine and Shugan Heluo Xingpi Decoction intervention, the physiological status of rats was significantly improved; serum levels of HYP, ALT, AST and Glo were significantly decreased, while serum levels of TP, Alb and A/G were significantly increased (all P < 0.05). Compared with the positive control group, serum levels of ALT and AST were significantly increased (all P < 0.05), while the levels of TP, Alb and A/G were significantly decreased (all P < 0.05) in low-dose group of Shugan Heluo Xingpi Decoction. H&E staining showed mild portal vein fibrosis with a few fibrous septa and mild steatosis of hepatocytes in the positive control group, obvious portal vein fibrosis with a few fiber septum in the low dose group, a few portal vein fibrosis in the medium dose group, while no obvious abnormality in the high dose group of Shugan Heluo Xingpi Decoction. Masson staining revealed that the therapeutic effect of high dose group of Shugan Heluo Xingpi Decoction on collagen deposition was superior to silibinin meglumine and medium and low dose of Shugan Heluo Xingpi Decoction (all P < 0.05), and was generally equivalent to high dose of Shugan Heluo Xingpi Decoction. Silibinin meglumine and medium and high doses of Shugan Heluo Xingpi Decoction inhibited more significantly the mRNA and protein expression of Wnt1, β-catenin and Cyclin D1 (all P < 0.05). Conclusion Shugan Heluo Xingpi Decoction shows anti-hepatic fibrosis effect, with a greater effect at higher doses. Regulating Wnt/β-Catenin signaling pathway may be one of the underlying molecular mechanisms.
