Subthalamic nucleus (STN) deep brain stimulation (DBS) has become an important surgical treatment of Parkinson disease, but its exact mechanism is still unclear.In this study, a 16-channel implantable microelectrode array (MEA) was prepared by micro-electromechanical system (MEMS) technique and later modified with platinum black/reduced Graphene Oxide/Nafion (Pt/RGO/Nafion) nanocomposites.Extracellular dopamine (DA) content and spike of dorsal striatum neurons were synchronously recorded before and after STN stimulation.The results showed that the dopamine content began to increase within 20 s after electrical stimulation and dropped to normal level after about 50 s, with the highest rising concentration of 1.72 μmol/L.At the same time, there was an increased spike activity of interneurons in the dopamine ascending phase, and the spike firing rate of medium spiny projection neurons (MSNs) was high when the concentration of DA was higher than the normal level.The MEA sensor can simultaneously record dopamine flux and physiological signals in situ, thus providing an ideal tool for neural information detection.

Objective: This study aims to investigate the impact of individual and family factors on anxiety and loneliness of middle school students during quarantine in the COVID-19 pandemic and to provide reference for discussing the possible effective intervention paths in the stress process of public health emergencies. Methods: A total of 11 596 students from junior and high schools in Shanghai were selected to complete the questionnaire with the stratified random cluster sampling method. Generalized Anxiety Disorder(GAD-7) and UCLA Loneliness Scale, University of California at Los Angeles(ULS-6) were used for the survey. Results: The prevalence of anxiety and loneliness were 34.78% and 52.44% respectively. The rate of anxiety and loneliness in girls (36.13%, 54.62%) was higher than that of boys (33.44%, 50.28%)(χ 2=17.03, 21.82, P<0.05). Logistic regression analysis showed that graduates (OR=1.34, 95%CI=1.18-1.52), students ranking in the middle (OR=1.25, 95%CI=1.08-1.45) or in the bottom 25% (OR=1.76, 95%CI=1.50-2.05), non only children in the family (OR=1.25, 95%CI=1.09-1.43) and low socioeconomic status (OR=1.42, 95%CI=1.23-1.65) were associated with increased risk of moderate and severe level of anxiety(P<0.05). Girls(OR=1.20, 95%CI=1.12-1.30), graduates(OR=1.13, 95%CI=1.04-1.24), non residents(OR=1.20, 95%CI=1.09-1.33), lower level of grades(OR=1.72, 95%CI=1.55-1.91) and not living with parents(OR=1.32, 95%CI=1.18-1.48) were associated with increased risk of loneliness(P<0.05). Conclusion During the quarantine period caused by the COVID-19 pandemic, negative emotions such as anxiety and loneliness among adolescents need attention, especially females, graduates, only children and students with low rankings or low socioeconomic status.

Enhanced Recovery After Surgery (ERAS) is a standardized perioperative care plan aimed at optimizing perioperative management through a series of evidence-based interventions. In recent years, guidelines related to ERAS in gynecologic oncology have been successively updated.

By using R language to deal with practical problems,we introduce two methods of obtaining time related receiver operation characteristic [ROC(t)] curves from survival data:1) nearestneighbor estimator of bivariate distribution (NNE) estimation:to obtain cumulative/dynamic ROCC/D(t) curves;2) Cox estimation:to obtain incident/dynamic ROCI/D (t) curves.The areas under the ROC(t) curves (AUC) obtained from the two methods fluctuate over time.The one obtained through NNE has bigger fluctuation than that obtained through Cox,while the mean of AUC of the two methods are similar.Time related ROC (t) can be effectively used to evaluate the diagnostic capacity of the marker in clinical trials,and help to select the best diagnostic time of the marker.According to the different scientific interests,researchers should select relevant methods for more accurate evaluation.

In recent years, the bloodstream infection rate of Gram-negative bacilli has continued to increase. Among them, drug-resistant bacteria have a higher mortality rate and longer hospital stay, especially the bloodstream infection of carbapenem-resistant Acinetobacter baumannii (CRAB). Polymyxin began to be used clinically in the 1950s and has antibacterial activity against multidrug resistant and poly drug-resistant Gram-negative bacilli. It can also be used as an effective permeation agent for the cell envelope of Gram-negative bacilli. Polymyxin is reserved for microbiologically clear drug-resistant Gram-negative bacilli infections. The World Health Organization classifies polymyxin as an antimicrobial drug with clinical significance for human infections and can be used to treat drug-resistant Acinetobacter baumannii infection. This article reviews the clinical treatment of polymyxin in bloodstream infections of drug-resistant Acinetobacter baumannii, to provide reference for clinical medication.

Objective: To describe the current status of the prevalence of co-morbid myopia and obesity among 7-18 years students in the Inner Mongolia Autonomous Region in 2021 and to analyze the moderating effect of lifestyle in this association ，so as to provide scientific basis for the establishment of the mechanism of Co-morbidity，Shared Etiology，and Shared Prevention of common diseases in children and adolescents. Methods: A total of 139 630 primary and secondary school students aged 7-18 years from Inner Mongolia Autonomous Region were selected by stratified random cluster sampling method in September,2021. Myopia was determined using distance visual acuity examination and refractive error examination, and obesity was determined according to the BMI classification criteria for overweight, obesity screening of Chinese school age children and adolescents. Used a questionnaire, healthy lifestyles were determined according to the American Heart Association s Healthy Lifestyle Score by totaling the six scores for smoking, alcohol consumption, diet, exercise, screen time, and sleep duration.The χ 2 test was used to compare the association between group differences in the co-morbidity rate of myopia and obesity. The multivariable Logistic regression model was used to explore the influencing factors of the co-morbidity of myopia and obesity, and the stratified analysis was used to analyze the moderating effect of lifestyles on the prevalence of the co-morbidity. Results: The prevalence of myopia and obesity co-morbidity among students aged 7-18 years old in the Inner Mongolia Autonmous Region in 2021 was 13.7%, higher among boys than girls ( 15.5 % vs. 11.8%), higher among those aged 10-12 years old than 7-9,13-15,and 16-18 years old (14.7%,13.7%, 13.3%, 12.0%), higher among other ethnic minorities than Han Chinese and Mongolians (15.3%, 14.0%, 12.5%), higher in urban areas than that in suburban areas(15.3%, 13.0%), and middle economic level tracts were higher than poor and good tracts (14.8%, 12.9 %, 12.6%) ( χ 2=392.37，115.73，62.80，119.02，121.60, P <0.05). Multivariable Logistic regression modeling showed that unhealthy lifestyles ( OR=1.24, 95%CI=1.19-1.29 ) and middle level of lifestyle score ( OR=1.15, 95%CI=1.10-1.19 ) students had higher prevalence of co-morbidity, and the results were statistically significant among both boys and girls, the age groups of 10- 12, 13-15, and 16-18 years old, as well as the Han and Mongolian ethnic groups (all P <0.05). Conclusion In 2021, the current situation of myopia and obesity co-morbidity and unhealthy lifestyles among primary and secondary school students in the Inner Mongolia Autonomous Region are not optimistic.

Objective:To investigate the association of urinary cadmium levels with peripheral leukocyte classification counts among middle-aged and older adults aged 40 to 89 years in selected areas of China.Methods:The research was based on the survey of the impact of soil quality of agricultural land on human health in typical areas conducted in 2019-2020. A total of 5 600 middle-aged and older adults aged 40 to 89 years were included by using a multi-stage stratified random sampling method. Baseline characteristics of the subjects were collected and physical examinations were performed. Random midstream urine was collected to measure urinary cadmium and urinary creatinine and fasting venous blood was collected to measure the leukocyte count, neutrophil count, lymphocyte count, monocyte count and eosinophil count. The linear mixed effect model was used to analyse the association of urinary cadmium levels with leukocyte classification counts, and the dose-response relationship between them was analyzed by using the restricted cubic spline (RCS) function.Results:The age of the subjects was (63.17±12.02) years; 2 851 (50.91%) were males; and the M ( Q 1, Q 3) of urinary creatinine-corrected urinary cadmium levels was 2.69 (1.52, 4.69) μg/g·creatinine. After adjusting for confounding factors, the results of linear mixed effects model analysis showed that for each 1-unit increase in urinary creatinine-corrected urinary cadmium level, the percentage change [% (95% CI)] of leukocyte count and lymphocyte count was -1.70% (-2.61%, -0.79%) and -1.57% (-2.86%, -0.26%), respectively. RCS function showed a negative linear relationship between urinary creatinine-corrected urinary cadmium levels and leukocyte counts and lymphocyte counts, respectively (all Pnon-linear>0.05). Conclusion:Urinary cadmium levels are negatively associated with leukocyte count and lymphocyte count among middle-aged and older adults aged 40 to 89 years in selected areas of China.
